This study was conducted to develop detailed evaluation indicator as a way for evaluating sustainable urban ecosystem health focused on ecological urban elements from an eco-cultural point of view after the appearance of Eco-cultural City to meet various needs. And this study was also conducted to search for ways to utilize the detailed evaluation indicator like institutionalization. Eco-cultural City was defined as a city where ecological environment and cultural environment coexist and was aimed to derive applicable planning indicators in Korea. For this, FGI was executed, planning indicators were derived, and suitability was examined. The weights were calculated based on the selected indicators through AHP expert survey. After getting the result of FGI, experts reviewed the adequacy of definition from Eco-cultural City and its necessity, and the applicability of planning indicators was examined with evaluation of suitability. As a result of evaluating suitability, it was judged that 41 indicators based on an overall average of 4 areas were relatively high on suitability and also important among sectors. As for the analysis result, the priority order in multistage classification was as followed : harmony between human and environment(B) 0.349, environmental resources(A) 0.266, city environment and quality of culture(C) 0.208, and role division and citizen participation(D) 0.177.

Given the difference in research performance in various scientific fields, this study aims to weight and valuate current indicators used for evaluation of scientific productions (publications), in order to adjust these indicators in comparison to each other and make possible a more precise evaluation of scientific productions. This is a scientometrics study using documentary, evaluative, and survey techniques. The statistical population consisted of 106 top Iranian researchers, scientists, and scientific and research managers. Then their research résumé information was gathered and analyzed based on research questions. In order to compare values, the data gathered from research production performance of the population was weighted using Shannon entropy method. Also, the weights of each scientific production importance according to expert opinions (extracted from other works) was analyzed and after adjustment the final weight of each scientific production was determined. A pairwise matrix was used in order to determine the ratios. According to the results, in the area of engineering sciences, patents (0.142) in the area of science, international articles (0.074) in the area of humanities and social sciences, books (0.174), and in the area of medical sciences, international articles (0.111) had the highest weight compared to other information formats. By dividing the weights for each type of publication, the value of each scientific production compared to other scientific productions in the same field and productions of other fields was calculated. Validation of the results in the studied population resulted in very high credibility for all investigated indicators in all four fields. By using these values and normalized ratios of publication indicators it is possible to achieve precise and adjusted results, making it possible to feasibly use these results in realistic policy making.

This study compared the nutritional quality of Korean adults's consumption of lunch prepared at home, commercial places, and institutions. The one day food intake data collected via 24-hour recall in the 2001 National Health and Nutrition Survey were analyzed. Individuals with 19-64 years of age were selected (n = 5,756). Sampling weights in the Survey were used to generate nationally representative estimates. Lunch was categorized into three groups according to the place where the lunch was prepared. home, commercial places, and institutions such as schools and work places. Comparison among the three groups was made for 19-39 years old men (n = 1,387) and women (n =1,572) and 40-64 years old men (n = 1,364) and women (1,433), respectively. The lunch prepared away from home contained more calories. The lunch prepared commercially was higher in calories percentages from fat than that prepared either at home or at institutions. Across the age and gender groups, lunch prepared at home contribute a high level of sodium intake. Among individuals with 40-64 years of age, but not those with 19-39 years of age, lunch prepared commercially was as sodium dense as that prepared at home. Among individuals with 19-39 years of age, the sodium density of lunch prepared commercially was about the same as that prepared at institutional food service of which the menus were planned by dieticians. Such differences in nutritional quality among meals prepared at home, commercial places, and institutions should be considered and applied for the content development of nutrition education and policy.

This analysis was performed to investigate the relationship between nutrition and anthropometric indices using the data from a cross-sectional survey of a large national sample, '98 Korean national health and nutrition examination survey. Subjects were selected by stratified multistage probability sampling design and completed dietary questionnares including food intakes for one day by 24-hour recall method. For this analysis, 6566 subjects were selected by age(over 20 years old). For anthropometry, height, weight, and waist- and hip- circumference were measured. They were classified by body mass index(BMI, weight(Kg)/$height^2 $($m^2 $)) and waist-hip ratio(WHR, waist circumference(Cm)/hip circumference(Cm)). The nutrients intake of subjects were compared with the recommended daily allowances(RDA). Mean adequacy ratio(MAR) was calculated. Mean heights, weights, BMIs were higher in the groups with nutrient intake over 125% of RDA than the lower intake groups for most nutrients. However, Mean WHR was the highest in the groups with nutrient intake under 75% of RDA for most nutrients excluding iron intake of women aged 20-64 years. Among women aged 20-64 years, means of MAR were 0.71 for obese individuals(BMI>30), 0.72 for subjects with underweight(BMI<18.5), and 0.76 for subjects with normal weight(18.5$\leq$BMI<25). Normal subjects has statistically significantly higher MAR than those of other groups. However, among elderly people aged over 65 years, obese group had the highest MAR, 0.68. Women with abdominal obesity(WHR>0.9) had lower MAR, 0.71 than those with normal weight(MAR=0.76). From these results, obesity and abdominal obesity seems to be the results of malnutrition including both undernutrition and overnutrition rather than simple problem of excess energy intake. Obesity in elderly people needs to be handled differently from adults.

패널 자료는 자료가 축적되는 만큼 그 가치가 증대된다. 이와 동시에 장기추적에 따른 표본이탈은 자료의 신뢰성을 떨어뜨린다. 국내 외 대부분의 패널조사에서 가중값 보정을 통해 표본 이탈 문제를 해결하고 있다. 본 논문에서는 패널자료에서 차수별 응답여부에 따라 연속 응답 그룹과 비연속 응답 그룹으로 나누고, 비연속 응답 그룹에 대한 적정 가중값 산출방법을 검토하였다. 연속/비연속 응답그룹을 구분하여 비연속 응답 그룹의 응답자 특성을 반영한 복합추정 방식의 가중값 작성방법을 제안하고, 그룹의 구분 없이 작성하였던 기존의 가중값 작성방법과 새로 제안한 복합추정 방식의 가중값 산출방법의 효율성을 모의실험과 실증분석을 통해 살펴보았다. 결과적으로 새로 제안한 복합추정 방식의 가중값 산출방법은 기존 방법 보다 편향을 대폭 감소시킴을 모의실험을 통해 볼 수 있었다. 한편, 제시한 가중값 작성방법을 한국고용정보원 고령화연구패널에 적용한 결과도 제시하였다.

Objectives: The Korean National Environmental Health Survey provides representative biomonitoring data for environmental pollutants in South Korea. Over the last decade, there have been various studies published using this data. In this study, we aimed to provide information and implications by reviewing each study. Methods: We searched comprehensive electronic databases from PubMed, Google Scholar, and Naver Academic database using the key words 'Korean National Environmental Health Survey' and 'KoNEHS' through March 2021. A total of 57 studies were selected after reviewing the relevance of the data. Results: The most frequently studied pollutants were heavy metals (10), Cotinine (8), Bisphenol A (7), and Phthalates (6), in that order. In particular, Phthalates, Bisphenol A, and Parabens were often studied together (6). A decline in urinary cotinine and heavy metals in the body was shown over time among studies on exposure association. It was demonstrated that Phthalates and Bisphenol A were significantly related to obesity and diabetes from the studies of health impacts. Cross-section study design, spot urine, and insufficient health status information were mostly reported as limitations of the data. Conclusion: Since research has been focused on adults, further investigations of children and adolescents are required. In this regard, it is necessary to maintain the consistency of the data structure and provide integrated weights for all ages. In addition, it would allow the measurement of several environmental pollutants by considering subsample design. Lastly, integrated studies with multi-cycles and the health effects from co-exposure to multiple chemicals would be expected to provide important knowledge.
