Longline fishery targeting tunas and tuna-like species is known to produce a significant amount of catch not only for the target species, but also for ecologically related species like sharks, marine turtles, sea birds and marine mammals. Recognizing this seriousness, tuna related regional fisheries management organizations (t-RFMOs) have established conservation and management measures (CMMs) to reduce bycatch and/or interaction with ecosystem vulnerable species including sea turtles and are obliged to implement bycatch mitigation measures and guidelines on safe release to their member countries. Along with development and strengthening of those measures, various case studies have been conducting to verify the effectiveness of bycatch mitigation for ecologically related species. This study examines the background and progress on developing CMMs of t-RFMOs and regulation programs of the United States related to sea turtles, which have recently become one of the main issues, and reviews case studies on sea turtle bycatch mitigation measures to find out the effectiveness of reducing bycatch rate and impacts to the fisheries. In order to respond the consultation process on certification determination with the United States, it was confirmed the current status of implementation on related measures conducted by Korean tuna longline fishery based on scientific observer data and survey for captains. Even though all Korean tuna longline fleets belong to the deep-set longline fishery (100-300m), which is not subject to the obligation of those mitigation measures, they are voluntarily implementing both measures, use of circle hook and whole finfish bait, regardless of which RFMO's Convention area they operate. And the national regulatory and management programs for sea turtle bycatch prevention adopted by Republic of Korea seems to be comparable in effectiveness to that of the United Stated. However, Korea needs to take preemptive measures in establishing sustainable fisheries, including the protection of the marine ecosystem and environment, as stronger requests are anticipated to be made by the international community on this matter.

This study was done to analyze the contents of food and nutrition information in daily newspapers. Articles in four newspapers(Chosun, Donga, Hankook, Joongang Ilbo) published during November 2003 to April 2004 were monitored. In analysis, 216 articles were used. Classifying the articles by topics, cuisine/cooking $(19.4\%)$ and food/ nutrition related to diseases $(18.1\%)$ were most common. Articles regarding food sanitation or safety, obesity and diet accounted for $12.5\%$, respectively. Other topics in articles included food culture$(11.1\%)$, balanced meals/eating habits $(10.6\%)$ and functional foods $(7.9\%)$. About $77\%$ of articles were written for unspecified persons. Regarding the types of articles, news articles made up $44\%$ of monitored articles, followed by feature articles $(14.8\%)$, advertisement by articles $(12.9\%)$, serials by professionals $(11.6\%)$, and information of daily life $(8.8\%)$. Nineteen percent of articles did not have specific sources, while $20.8\%$ were based on interviews with professionals. Other sources of articles included research reports $(14.8\%)$, field reports $(12.1\%)$ and literature $(8.8\%)$. Contents analysis showed that four-fifth of articles were evaluated as 'contents and titles are consistent', 'not difficult to understand', 'contents are not exaggerated', and 'information is not overgeneralized'. Seventy-one percent of articles were evaluated positively on increasing awareness regarding food/nutrition, while $56.5\%$ were evaluated as providing practical information. The major problems in articles were 'intentional or indirect advertisements of specific items/companies' ($74.6\%$ of articles applicable), 'lacking in scientific basis/explanation' $(65.3\%)$, 'presenting unbalanced information due to focusing on specific area' $(46.7\%)$, 'unclearness of contents' $(38.4\%)$, and 'lacking in explanation of technical terms' $(35.2\%)$. To provide reliable information, stating the sources of articles clearly and supplementing the articles with scientific basis and balanced information on specific topics are needed. It is also necessary to explain the contents and technical terms clearly and to reduce the contents of intentional, indirect advertisement in nutrition-related articles.

Objectives: Excess sodium intake has been linked to obesity and obesity-related indices. However, the scientific evidence for this association is inadequate. The purpose of this study was to investigate the association between urinary sodium excretion and obesity-related indices among Korean adults. Methods: A convenience sample of 120 subjects (60 obese and 60 non-obese subjects) were recruited applying frequency matching for sex and age between two groups. Sodium intake level was assessed through 24-hour urine collection. Obesity-related metabolic risk factors, including fasting blood lipid indices, subcutaneous and visceral fat through computed tomography (CT), insulin resistance indices, blood pressure and liver enzymes were measured in all subjects. These obesity-related metabolic risk factors were compared between obese and non-obese group according to sodium excretion levels (<110 mEq/day, 110~180 mEq/day, >180 mEq/day). Results: After adjusting for age, gender, health behaviors (smoking, exercise, drinking), and energy intake, several obesity-related metabolic risk factors, including abdominal circumference, body fat percentage, subcutaneous and visceral fat, triglyceride, and systolic blood pressure were found to be significantly deteriorated as the sodium excretion level increases. In addition, multivariate adjusted-odds ratios of abdominal obesity, high blood triglyceride, and high blood pressure were found significantly higher in the highest sodium excretion group compared to the lowest group. The mean number of metabolic syndrome risk factors was also significantly greater in the highest sodium excretion group than in the lowest group. Conclusions: The current study findings suggested that high sodium intake can affect obesity and metabolic syndrome risk negatively, implying the necessity of future research on low-sodium diet intervention in relation to obesity and related health problems.

황우석 박사 연구팀의 논문조작 사건은 우리 사회에서 그동안 견고하게 이어져오던 학문 연구자와 그 연구 활동에 대한 신뢰를 크게 흔들어놓았다. 이 사건 이후에 우리의 연구자사회와 과학계는 반성 및 성찰 과정을 통해 많은 변화를 겪었다. 우리는 연구자사회가 먼저 나서서 제기된 의혹을 철저하게 규명하려는 능동적인 노력을 보여줄 때에 연구자사회에 대한 신뢰, 연구 활동에 대한 신뢰는 크게 흔들리지 않았음을 경험해왔다. 하지만 연구부정행위에 대해 소극적으로 대응하는 반대의 경우들이 아직은 더 많기에, 우리 연구자사회가 가야 할 길은 여전히 험난하다. 따라서 학문이나 학습 영역의 연구 및 학습 부정행위 사례가 불필요하게 확대 해석되는 일을 막는 것은 연구자 및 학습자 사회 내부에 정치, 경제, 사회 등 제 분야의 갖가지 이해관계들에서 벗어난 자율적인, 또한 의사결정이 합리적으로 이뤄지는 체계를 얼마나 잘 갖추고 있느냐에, 그리고 사회적 사건으로 비화하기 이전에 먼저 이런 부조리를 미리 예방하려는 세심한 체계를 얼마나 잘 갖추고 있느냐에 달려 있다. 이러한 맥락에서 필자는 사후적 차원이 아니라 사전적 차원, 즉 연구자 및 학습자의 자율적 자정 체계 마련을 위한 방법, 즉 연구 학습윤리의 규범 연구가 왜 중요한 것인지를 탐색할 것이다. 논의의 분명한 진행을 위해서는 우선 연구 학습윤리가 무엇인지를 좀 더 분명하게 규명하고 정의할 필요가 있다.(2) 그리고 이 과정에서 연구 학습윤리가 왜 규범화되어야 하는지를 살펴야 할 것이다.(3) 이어서 만일 연구 학습윤리가 규범화될 수 있는 것이라면, 그것이 왜 정당화되어야 하는지를 논증하면서,(4) 이 글을 마무리할 것이다.(5)

In this study, focus group interviews were used to investigate female university students' eating behavior, factors related to eating behavior, information sources for nutrition, and formats for nutrition education. Thirty-six students participated in one of five focus groups during December 1998 in Seoul. Focus group discussions were video, audio-taped, transcribed and analyzed by major themes. Results showed that subjects have undesirable eating behaviors, such s eating irregular meals and skipping meals. These behaviors are caused by a lack of time, habit, or for the purpose of losing weight. The students tended to have unbalanced diets and frequently ate out. They had a large amount for dinner and frequently snaked when stressed or had an empty stomach. Most of them were interested in weight control and had attempted to lose weight, but they did not participate in regular exercise. The most frequently used source for nutrition information was the mass media, but much nutrition information was based on what they learned from home economics class during middle to high school. They received more support from mothers, elder sisters, and friends for eating behaviors, such s lowering caloric intake and losing weight. In nutrition education, they wanted to learns behaviorla skills to adopt healthy behaviors, including meal planning, applying scientific weight control methods, exercise that fit into their lives, and stress management. They also mentioned that nutrition screening and assessment should be a part of nutrition education programs. As a method for nutrition education, subjects preferred an individualized approach to group education. These results provide the qualitative information for developing nutrition education programs which will be implemented for Korean University students.

Purpose: The purpose of the study was to identify the characteristics of doctoral dissertations in nursing science submitted since 2000. Method: Three-hundred and five dissertations of six schools of nursing published from 2000 to 2006 in Korea were analyzed with the categories of philosophy, method, body of knowledge, research design, and nursing domain, Result: In philosophy, 82% of all dissertations were identified as scientific realism, 15% were relativism, and 3% were practicism. Two-hundred and fifty dissertations (82%) were divided into a quantitative methodology and 55 dissertations (18%) were qualitative methodology. Specifically, 45% were experimental, 23% methodological, 13% survey and 17% qualitative designed researches. Prescriptive knowledge was created in 47% of dissertations, explanatory knowledge in 29%, and descriptive knowledge in 24%. Over 50% of all research was studied with a community-based population. In the nursing domain, dissertations of the practice domain were highest (48.2%). Conclusion: Dissertations since 2000 were markedly different from the characteristics of the previous studies (1982-1999) in the increase of situation-related, prescriptive and community-based population studies. A picture of current nursing science identified in this study may provide a future guideline for the doctoral education for nursing.

This survey was conducted to evaluate with 457 health professionals from July, 1999 to September, 1999 the awareness of and satisfaction with the nutrition labeling system in Korea and to determine a desirable labeling system. Professors of food and nutrition and nutrition researchers in the food industry had the hightest scores on awareness of the nutrition labeling system(75.6% and 73.4%, respectively), which was significantly different from each other by occupation(p < 0.01). Frequently checked labeling information were expiration date, production date, price, and company respectively. Special nutrient food producers(56.9%), dietitians(49.3%), nurses(48.1%), researchers(42.3%) answered moderately on satisfaction with nutrition information for products, which was statistically significant(p < 0.01). This suggests that health professionals were unsatisfied with the present nutrition labeling system. In nutrition focusing statements, nutrient content claims, health claims, and working periods were significantly related with nutrition focusing statements and health claims, but not with nutrient content claims : the subject who had been working for more than 10 years and less than 5 years had positive thoughts or those matters while the subjects whose working periods were between 10 and 5 years had the lowest score. The most desirable labeling units were serving size(65.1%). Ninety two percent of the subjects wanted absolute nutrient contents in food and their percentage of the KRDA. Eight nine percent of health professionals agreed that the health claims should be used only with scientific approval by the government or food research institutions. Only 4.4% of subjects were satisfied with current regulations of health claims(p < 0.001). More studies regarding labeling units, their range and nutrient reference values are needed. The opinions of health professionals in nutrition labeling system should discussed to establish a desirable nutrition labeling system.

Television news programs are becoming significant source of health information. This study aims at investigating the current state of health coverage of the prime time news program in Korea. Data were collected from KBS 9 0'clock news in the period of thirteen months. from December 1. 1998. to November 1. 1999. The data were analyzed using content analysis method. and the reliability degree was 99.7% according to the Holsti's inter-coder reliability test. The current research classified 489 health related news items into 49 sub-categories and five health categories through content analysis. Some of the basic results of this study are as follows. 1. The frequency according to health category, health maintenance promotion(57.3%) topped followed by disease prevention(23.2%), disease treatment(14.9%), life ethics(4.0%), and growth development(0.6%). 2. According to human developmental age. for the most part(80.1 %) is applicable to the entire range of human developmental age. 3. Health maintennance promotion category take top of health category by the rate of 57.3% and contain 20 sub-categories. 4. News items in the life ethics category, which had six sub-categories. occupied only four percent of the total health related news. News in the growth development category included two sub categories and occupied 0.6% of the total news items. 5. In disease prevention and disease treatment category, infectious disease(33.2%) showed the highest percentage according to the WHO's international disease classification system. Disease prevention occupied 23.2% and contained eleven sub-categories while disease treatment occupied 14.9% and included ten sub-categories. Television news coverage on health showed a wide variety of selection in terms that they are reporting various issues. This study, however, found that some news items were confusing and failing in presenting scientific evidences. It is suggested that the television coverage on health could be beneficial to most of viewers in receiving important health information and guidelines, only if they are utilizing their own sound discretion in consuming those news.

It is not clear to assume the history of dyeing by persimmon juice without an early knowledge of an accurate record. However, the beginning of persimmon dyeing in Korea is estimated to be around the $13^th$-$14^th$ century, even though there are no supporting records. On the other hand, there are definite records of persimmon dyeing in Japan from around the 17th century. Persimmon juice was originally used for fishing tools in both Korea and Japan, but upon entering the Modern Era it eventually transfigured into a dye for fabric. In Korea, persimmon-dyed fabrics were used for traditional clothing until it also became a popular choice for modern clothes in the 1990s. In Japan, persimmon juice was originally used for varnishing surfaces of household items, but it recently became a material for arts, crafts, and even apparels. The main difference between persimmon dyeing of the two countries is the presence and absence of the fermentation process. In Korea, persimmons are picked and water is immediately added to its juice to produce the dye. In contrast, Japan produces a fermented persimmon dye. As a result, in Korea the dye can not be preserved for long periods, whilst in Japan it is matured in the storage for 2-3 years. Today's pursuit of eco-friendliness and wellness has prompted an inclination towards natural material clothes. Therefore, it is necessary for both countries to push scientific research into improving the storage methods and colorfastness of persimmon-dyed products for the increase of use consumption in other areas of persimmon and arrowroot dyed fabrics, and the development of environment friendly materials.
