The Korea Coast Guard's Use of Force Against Chinese Fishing Vessels: A Note

In November 2016, the Korea Coast Guard published the “Manual for the Use of Weapons” in response to the sometimes violent resistance of Chinese fishing vessels to the law enforcement activities of the Korea Coast Guard. This article looks at this manual, the possible uses of crew-served weapons, and the international legal precedents for the use of force at sea.     

Epidemiology of Waterskiing Injuries

Coast Guard statistics indicate a national boating fatality rate of 9.6 deaths per 100,000 crafts. In 1977 in California, five fatalities and 70 serious injuries were directly attributable to waterskiing. The four cases reported here include three patients with propeller injuries, including one nearly fatal amputation. In each case basic measures for boating safety were overlooked.     

Risk factors of posttraumatic stress disorder among survivors after the 512 Wenchuan earthquake in China

This study investigated the psychological reactions of survivors of the 512 Wenchuan earthquake in China and the risk factors associated with those reactions. The Impact of Event Scale-Revised (IES-R), Type D Scale-14 (DS14), a self-developed trauma experience questionniare, and a demographic questionnaire were administered to 956 earthquake survivors (389 males and 567 females) in Mianzhu, one of the cities most affected by the earthquake. The results showed that postraumatic stress disorder (PTSD) symptoms affected 84.8% of survivors one to two months after the earthquake. Significant risk factors associated with PTSD symptoms included: (1) being female; (2) older age; (3) higher exposure to traumatic events during the earthquake; and (4) negative affect in Type-D personality.     

Levels of antibodies to microorganisms implicated in atherosclerosis and of C-reactive protein among atomic bomb survivors

Although it has been suggested that cardiovascular disease incidence is increased among atomic bomb survivors, the existence of a causal relationship between radiation exposure and atherosclerosis is unclear. Microbial infections, including those caused by Chlamydia pneumoniae, Helicobacter pylori and cytomegalovirus, have recently been implicated in atherosclerosis. Since immune function is somewhat impaired among atomic bomb survivors, their immune defense against such infections might be diminished. To investigate this possibility, we measured antibody levels to the above microorganisms in the sera of survivors. We found that the levels of IgG and IgA antibodies to Chlamydia pneumoniae decreased significantly with radiation dose, whereas the levels of IgG antibodies to Helicobacter pylori or cytomegalovirus remained unchanged. The inflammation marker C-reactive protein was significantly and positively associated with level of antibodies to Chlamydia pneumoniae only in heavily exposed (>or=1000 mGy) survivors. These results may suggest that among atomic bomb survivors, immune response to Chlamydia pneumoniae is diminished and chronic inflammatory reactions related to Chlamydia pneumoniae infection are present.     

Human reactions to the Nazi concentration camps: a summing up

With the passing of time, it becomes increasingly unlikely that major studies of concentration camp survivors will appear. Nearly forty years have gone by since the camps were liberated. Most survivors have died, and their children are approaching middle age. This paper provides a brief summary of the available data. Beginning with an account of the events leading to the Holocaust, it goes on to summarize the major types of psychological defenses employed by the prisoners, and also describes the group or social activity in the camps. The long lasting psychological, psychiatric, and medical consequences of internment are then reviewed. The paper concludes with a discussion of studies of the children of survivors.     

International dissemination of epidemic Vibrio cholerae by cargo ship ballast and other nonpotable waters.

In 1991 and 1992, toxigenic Vibrio cholerae O1, serotype Inaba, biotype El Tor, was recovered from nonpotable (ballast, bilge, and sewage) water from five cargo ships docked in ports of the U.S. Gulf of Mexico. Four of these ships had taken on ballast water in cholera-infected countries; the fifth took on ballast in a noninfected country. Isolates examined by pulsed-field gel electrophoresis were indistinguishable from the Latin American epidemic strain, C6707; however, they differed significantly from the endemic Gulf Coast strain (VRL 1984), the sixth-pandemic strain (569-B), and a V. cholerae non-O1 strain isolated from a ship arriving from a foreign port. On the basis of our findings, the Food and Drug Administration recommended that the U.S. Coast Guard issue an advisory to shipping agents and captains requesting that ballast waters be exchanged on the high seas before entry of ships into U.S. ports.     

Comorbidity trajectories in working age cancer survivors: A national study of Swedish men

BackgroundA large proportion of cancer survivors are of working age, and maintaining health is of interest both for their working and private life. However, patterns and determinants of comorbidity over time among adult cancer survivors are incompletely described. We aimed to identify distinct comorbidity trajectories and their potential determinants.MethodsIn a cohort study of Swedish men born between 1952 and 1956, men diagnosed with cancer between 2000 and 2003 (n = 878) were matched with cancer-free men (n = 4340) and followed over five years after their first year of survival. Comorbid diseases were identified using hospital diagnoses and included in the analysis using group-based trajectory modelling. The association of socioeconomic and developmental characteristics were assessed using multinomial logit models.ResultsFour distinct comorbidity trajectories were identified. As many as 84% of cancer survivors remained at very low levels of comorbidity, and the distribution of trajectories was similar among the cancer survivors and the cancer-free men. Increases in comorbidity were seen among those who had comorbid disease at baseline and among those with poor summary disease scores in adolescence. Socioeconomic characteristics and physical, cognitive and psychological function were associated with types of trajectory in unadjusted models but did not retain independent relationships with them after simultaneous adjustment.ConclusionsAmong working-age male cancer survivors, the majority remained free or had very low levels of comorbidity. Those with poorer health in adolescence and pre-existing comorbid diseases at cancer diagnosis may, however, benefit from follow-up to prevent further increases in comorbidity.     

Applicability and cost-effectiveness of the Systolic Blood Pressure Intervention Trial (SPRINT) in the Chinese population: A cost-effectiveness modeling study

BackgroundThe Systolic Blood Pressure Intervention Trial (SPRINT) showed significant reductions in death and cardiovascular disease (CVD) risk with a systolic blood pressure (SBP) goal of <120 mm Hg compared with a SBP goal of <140 mm Hg. Our study aimed to assess the applicability of SPRINT to Chinese adults. Additionally, we sought to predict the medical and economic implications of this intensive SBP treatment among those meeting SPRINT eligibility.Methods and findingsWe used nationally representative baseline data from the China Health and Retirement Longitudinal Study (CHARLS) (2011–2012) to estimate the prevalence and number of Chinese adults aged 45 years and older who meet SPRINT criteria. A validated microsimulation model was employed to project costs, clinical outcomes, and quality-adjusted life-years (QALYs) among SPRINT-eligible adults, under 2 alternative treatment strategies (SBP goal of <120 mm Hg [intensive treatment] and SBP goal of <140 mm Hg [standard treatment]). Overall, 22.2% met the SPRINT criteria, representing 116.2 (95% CI 107.5 to 124.8) million people in China. Of these, 66.4%, representing 77.2 (95% CI 69.3 to 85.0) million, were not being treated for hypertension, and 22.9%, representing 26.6 (95% CI 22.4 to 30.7) million, had a SBP between 130 and 139 mm Hg, yet were not taking antihypertensive medication. We estimated that over 5 years, compared to standard treatment, intensive treatment would reduce heart failure incidence by 0.84 (95% CI 0.42 to 1.25) million cases, reduce CVD deaths by 2.03 (95% CI 1.44 to 2.63) million cases, and save 3.84 (95% CI 1.53 to 6.34) million life-years. Estimated reductions of 0.069 (95% CI −0.28, 0.42) million myocardial infarction cases and 0.36 (95% CI −0.10, 0.82) million stroke cases were not statistically significant. Furthermore, over a lifetime, moving from standard to intensive treatment increased the mean QALYs from 9.51 to 9.87 (an increment of 0.38 [95% CI 0.13 to 0.71]), at a cost of Int$10,997 per QALY gained. Of all 1-way sensitivity analyses, high antihypertensive drug cost and lower treatment efficacy for CVD death resulted in the 2 most unfavorable results (Int$25,291 and Int$18,995 per QALY were gained, respectively). Simulation results indicated that intensive treatment could be cost-effective (82.8% probability of being below the willingness-to-pay threshold of Int$16,782 [1× GDP per capita in China in 2017]), with a lower probability in people with SBP 130–139 mm Hg (72.9%) but a higher probability among females (91.2%). Main limitations include lack of specific SPRINT eligibility information in the CHARLS survey, uncertainty about the implications of different blood pressure measurement techniques, the use of several sources of data with large reliance on findings from SPPRINT, limited information about the serious adverse event rate, and lack of information and evidence for medication effectiveness on renal disease.ConclusionsAlthough adoption of the SPRINT treatment strategy would increase the number of Chinese adults requiring SBP treatment intensification, this approach has the potential to prevent CVD events, to produce gains in life-years, and to be cost-effective under common thresholds.

Tao Chen and colleagues estimate the cost-effectiveness of intensive blood pressure intervention in Chinese populations at high risk for cardiovascular disease.     

Reassessing the Value of U.S. Coast Guard At-Sea Fishery Enforcement

The U.S. Coast Guard (USCG) is responsible for enforcing federal fisheries laws at sea. The USCG routinely reports high compliance rates and uses them as evidence that its program is successful at deterring fisheries violations. Research presented in this article indicates that high USCG-reported compliance rates vastly overestimate the actual rates and enforcement success because USCG at-sea inspections fail to detect many actual violations. Using high USCG-observed compliance rates as an indicator of successful enforcement is misleading, adversely influencing voluntary compliance with fishing regulations, and prevents fishery managers from recognizing illegal fishing as a significant problem and creating strategies for addressing it.     

Improvement in Salmonella detection in milk and dairy products: comparison between the ISO method and the Oxoid SPRINT Salmonella test

The Oxoid SPRINT Salmonella test was compared with the ISO method (ISO 6579: 1993) for the detection of Salmonella in milk and dairy products. Samples were artificially contaminated, in some cases with sublethally injured salmonellas. Experiments with raw milk, soft cheese made from heat-treated milk (mould-ripened and with smear) and soft cheese with smear made from raw milk showed no significant differences between the SPRINT and ISO methods. With dried milk products and mould-ripened soft cheese made from raw milk the reference method gave significantly more positive results. The addition of ferrioxamine E to pre-enrichment (ISO) or pre-enrichment/enrichment broth (SPRINT test) did not improve Salmonella detection.     

“We lost all we had in a second”: coping with grief and loss after a natural disaster

Natural disasters cause immense suffering among affected communities. Most occur in developing countries, which have fewer resources to respond to the resulting traumas and difficulties. As a consequence, most survivors have to rely on their own coping resources and draw from what support remains within family, social networks and the wider community to manage and deal with their losses and consequent emotional distress. Taking the 2004 Asian tsunami as an example, this article reports findings from a qualitative study designed to investigate how survivors responded in Sri Lanka, and the range of coping strategies adopted and resources mobilized. In‐depth interviews were conducted with 38 survivors purposively sampled from the Matara district of southern Sri Lanka. Survivors' accounts emphasized the importance of extended supportive networks, religious faith and practices, and cultural traditions in facilitating recovery and sustaining emotional well‐being. Government and external aid responses that promoted these, through contributing to the re‐establishment of social, cultural, and economic life, were particularly valued by participants. Recourse to professional mental health care and Western psychological interventions was limited and survivors preferred to seek help from traditional and religious healers. Our findings tentatively suggest that long‐term mental health following disaster may, in the first instance, be promoted by supporting the re‐establishment of those naturally occurring resources through which communities traditionally respond to suffering.     

Sea Control by Other Means: Norwegian Coast Guard Operations Under International Maritime Law

Abstract

This article examines the development and peacetime activities of the Norwegian Coast Guard through the lens of sea control. It argues that the creation of economic and fisheries protection zones has dramatically shaped the extent to which a smaller naval power, like Norway, has had to increase its ability to monitor and control maritime space. Although the maritime means and ends vary widely between peacetime and wartime contexts, the fundamentally contested aspect of sea use can still be discerned in the influence of international maritime law on Norwegian seapower.     

<Emphasis Type="Italic">Terebellides irinae</Emphasis> sp. n., a new species of <Emphasis Type="Italic">Terebellides</Emphasis> (Polychaeta: Terebellidae) from the Arctic Basin

A new polychaete species of the family Terebellidae, Terebellides irinae sp. n., has been described from materials collected in the Canadian Basin by the international Hidden Ocean 2005 expedition on board the US Coast Guard icebreaker (WAGB-20) Healy. The new species differs from other closely related species by its underdeveloped ventral branchial lobes that are at least two times shorter than the dorsal ones, sometimes reduced to barely noticeable cones and in that the aciculum-like neurochaetes of the 6th setigerous segment are curved at a right angle and have a thin capillaceous tip. Specimens of this polychaete worm are small, no more than 15 mm long.     

Improved bioluminescent enzyme immunoassay for the rapid detection of Salmonella in chicken meat samples

AIMS: To evaluate an improved bioluminescent enzyme immunoassay (BEIA) using biotinylated firefly luciferase for the rapid detection of Salmonella in naturally contaminated chicken meat samples. METHODS AND RESULTS: Capture agents and lipopolysaccharide (LPS) extraction reagents for Salmonella were investigated to improve the sensitivity of the BEIA. Also, the use of Oxoid SPRINT (Simple Pre-enrichment and Rapid Isolation New Technology) as a pre-enrichment and selective medium for 26-h BEIA detection of Salmonella in chicken meat samples was examined. The use of polymyxin B as a capture agent on solid support and 3-[(3-Cholamidopropyl) dimethylammonio] propanesulfonic acid (CHAPS) for extraction of the LPS facilitated sensitive detection of Salmonella. Of 120 chicken meat samples, 25 samples were positive using the improved BEIA with the SPRINT and 25 samples were positive using the SPRINT followed by the standard isolation methods. CONCLUSIONS: The improved BEIA, in which polymxin B was used as a capture agent and CHAPS was used for extraction of the antigen, had a sensitivity of 96.0% and a specificity of 98.9% for the detection of Salmonella in chicken meat. SIGNIFICANCE AND IMPACT OF THE STUDY: The improved BEIA combined with the SPRINT medium for the detection of Salmonella in chicken meat samples produced comparable results to the culture methods in 26 h.     

Biotransformation of monoaromatic and chlorinated hydrocarbons at an aviation gasoline spill site

A shallow water table aquifer under the U.S. Coast Guard Air Station at Traverse City, MI, has acclimated to the aerobic and anaerobic transformation of monoaromatic hydrocarbons (BTX) released from an aviation gasoline spill. The aquifer also exhibits reductive dechlorination of a chlorinated solvent spill adjacent to the aviation gasoline spill. The groundwater is buffered near neutrality. The aviation gasoline plume is methanogenic and the aquifer contains enough iron minerals to support significant iron solubilization. Field evidence of both aerobic and anaerobic biotransformation of monoaromatics was confirmed by laboratory studies of aquifer material obtained from the site. In the laboratory studies, the removal of the monoaromatics in the anaerobic material was rapid and compared favorably with removal in aerobic material. The kinetics of anaerobic removal of monoaromatics in the laboratory were similar to the kinetics at field scale in the aquifer. Biotransformation of the chlorinated solvents was not observed until late in the study, when daughter products from reductive dechlorination of the chlorinated solvents were identified by GC/MS.     

Associations between Work Environment and Psychological Distress after a Workplace Terror Attack: The Importance of Role Expectations,Predictability and Leader Support

Experiencing terrorism is associated with high levels of psychological distress among survivors. The aim of the present study was to examine whether work environmental factors such as role clarity and predictability, role conflicts, and leader support may protect against elevated levels of psychological distress after a workplace terrorist attack. Data from approximately 1800 ministerial employees were collected ten months after the 2011 Oslo bombing attack which targeted the Norwegian ministries. The results show that after a traumatic event, lower role conflicts, higher role clarity, higher predictability, and higher leader support were independently associated with lower psychological distress. These findings suggest that the workplace environment may be a facilitator of employees’ mental health after stressful events.     

Prevalence and Risk Factors for Depressive Reaction among Resident Survivors after the Tsunami following the Great East Japan Earthquake,March 11, 2011

Objectives

The Great East Japan Earthquake caused a gigantic tsunami which devastated coastal areas of northern Japan on 11 March 2011. Despite the large number of ‘resident survivors’ who continued to reside in their damaged houses on the second or upper floors, research on the mental health of these individuals has been limited. This study explored the prevalence of depressive reaction and risk factors for depressive reaction among these resident survivors.

Methods

A cross-sectional household health support needs screening was conducted for resident survivors in Higashi-Matsushima city, Miyagi prefecture, two to four months after the tsunami. The health interview that was conducted including mental status, assessed by the Patient Health Questionnaire-2 (PHQ-2).

Results

Of 5,454 respondents, 8.1% had depressive reaction. After adjustment by the number of weeks from the tsunami and the mortality rate at each respondent''s place of residence, depressive reaction was significantly associated with house flooding below or above the ground floor (odds ratios of 1.92, 2.36, respectively), the unavailability of gas supply (odds ratio, 1.67), being female (odds ratio, 1.47), middle aged or elderly (odds ratios of 2.41, 2.42, respectively), regular intake of psychotropic medicine(s) since before the tsunami (odds ratio, 2.53) and the presence of one to five or more than six cohabiters (odds ratios of 0.61, 0.52, respectively).

Conclusions

The results suggest a considerable psychological burden (depressive reaction) following the tsunami among resident survivors. Special supports for families with psychiatric problems need to be considered among resident survivors. Restoration of lifeline utilities and the strengthening of social ties of persons living alone may help prevent depressive reaction among resident survivors after a tsunami.     

Diet composition and foraging ecology of U.S. Pacific Coast groundfishes with applications for fisheries management

Determining the prey composition and foraging habitats of U.S. Pacific Coast groundfishes are specified management directives that have not received much scientific attention. To address this knowledge gap, we conducted a meta-analysis of the feeding ecology of 18 commercially important species and their life stages during a recent review of Pacific Coast groundfish essential fish habitat. A Major Prey Index was developed to evaluate relative importance among 47 prey taxa. Based on this metric, unidentified teleosts, euphausiids, and brachyuran crabs were the most important prey groups. When 14 generalized prey categories were used, fishes represented the dominant taxon (mean % weight or volume = 32.3) followed by shrimps (11.5), crabs (10.0), and euphausiids (9.5). PERMANOVA results indicated that species-specific differences were the primary source of dietary variability among tested variables (life stage, functional group, taxonomic group). Pacific Coast groundfishes mainly were characterized as mesopredators with estimated trophic levels ranging from 3.4 to 4.2. Foraging habitats differed significantly among functional (benthic, demersal, pelagic) and taxonomic (elasmobranch, roundfish, rockfish, flatfish) groups. Using hierarchical agglomerative cluster analysis, we identified a significantly distinct trophic guild that consumes mainly polychaetes and hard-shelled molluscs (juvenile, juvenile–adult Dover Sole; juvenile–adult English Sole) and another that specializes on euphausiids (juvenile Pacific Hake; juvenile–adult Darkblotched Rockfish). Our findings filled substantial data gaps in the trophic ecology and habitat-based management of commercially important species and can be used to inform future reviews of Pacific Coast groundfish essential fish habitat.     

Protozoa in Subsurface Sediments from Sites Contaminated with Aviation Gasoline or Jet Fuel

Numbers of protozoa in the subsurface of aviation gasoline and jet fuel spill areas at a Coast Guard base at Traverse City, Mich., were determined. Boreholes were drilled in an uncontaminated location, in contaminated but untreated parts of the fuel plumes, and in the aviation gasoline source area undergoing H₂O₂ biotreatment. Samples were taken from the unsaturated zone to depths slightly below the floating free product in the saturated zone. Protozoa were found to occur in elevated numbers in the unsaturated zone, where fuel vapors mixed with atmospheric oxygen, and below the layer of floating fuel, where uncontaminated groundwater came into contact with fuel. The same trends were noted in the biotreatment area, except that numbers of protozoa were higher. Numbers of protozoa in some contaminated areas equalled or exceeded those found in surface soil. The abundance of protozoa in the biotreatment area was high enough that it would be expected to significantly reduce the bacterial community that was degrading the fuel. Little reduction in hydraulic conductivity was observed, and no bacterial fouling of the aquifer was observed during biotreatment.     

Oxygen Release from Rice Seedlings

Oxygen release from root systems of individual rice seedlings was measured polarographically employing an oxygen monitor with a Clark electrode. The oxidizing capacity of four rice varieties was correlated with their relative yielding abilities and with their reactions to Straighthead (SH) and Mild Sulfide Disease (MSD). These data support previous findings which link SH and MSD with rice-toxic levels of soluble sulfides in Gulf Coast (U.S.A.) rice soils containing excess iron.
