With the prosperous economy, the status of diet and nutrition among the urban and rural Chinese population has been improved significantly. This paper will focuses on three main surveys in China. (1)'Food and Nutrition Surveillance System in China': Phase I focused on analysis of previous data. Phase II was a pilot survey initiated in Beijing, Hebei, Heilongjiang, Ningxia, Zhejiang, Guangzhou, and Sichuan in 1990. (2) 'The China Health and Nutrition Survey' is an ongoing longitudinal project covered 8(9) provinces in 1991,1993,1997,2000. This paper will analysis the adults aged 18 45 of 1991, 1993, 1997, and 2000. (3) Survey on the status of nutrition and health of the Chinese (2002) is an across sectional study covered 31 provinces, autonomous region and the municipalities. The data was used to analyze the status of food consumption and dietary nutrients intake of Chinese population. In the past ten years, the prevalence of malnutrition and nutrition deficiency has been continuously decreased. The consumptions of animal products, milk, and edible oil have been increased, while the dairy and legume products consumption decreased. The unbalance was showed with a downward trend in cereals, vegetables and fruits consumption and a significant increase in animal products and oil intake among urban people. Dietary pattern of some subjects went away to 'high energy density' diet. The deficiency of calcium, retinal and ascorbic acid etc, especially in the rural areas still exist. China is undergoing a remarkable, but undesirable, rapid transition towards a stage of the nutrition transition characterized by high rates of DR NCDs in a very short time. China is facing the dual challenges of nutrition deficiency and nutrition imbalance. The results can help to understand the dietary structure and the status of nutrition among Chinese people over the past years. It will provide the basis for formulating relevant state policies.

The integrative ecological approaches of chemical assessments, physical habitat modelling, and multi-metric biological health modelling were applied to Gwanpyeong Stream within Gap-Stream watersheds to evaluate environmental impacts on the constructions of residential and commercial complex. For the analysis, the surveys conducted from 45 sites of reference streams within the Gap-Stream watershed and 3 regular sites during 2009 - 2010. Physical habitat health, based on the habitat model of Qualitative Habitat Evaluation Index(QHEI) declined from the headwaters(good - fair condition) to the downstream(poor condition). Chemical water quality, based turbidity and electric conductivity(EC), was degraded toward to the downstream, and especially showed abrupt increases, compared to the values of control streams(CS). Also, concentrations of chlorophyll-a in the downstreams were greater compared to the control stream(CS), indicating an eutrophication. Biological health conditions, based on the Index of Biological Integrity(IBI) using fish assemblages, averaged 19.3 which is judged as a fair condition by the biological criteria of the Ministry of Environment, Korea. The comparisons of model metric values in sensitive species and riffle-benthic species on the Maximum Species Richness Line(MSRL) of 45 reference streams indicated a massive disturbances in all sampling locations. Also, tolerance guild and trophic guild analyses suggest that dominances of tolerant species and omnivores were evident, indicating a biological degradation by habitat disturbances and organic matter pollutions. There was no distinct longitudinal variations of IBI model values from the headwater to the downstream in spite of slight chemical and habitat health gradients among the sampling sites. Overall, integrative ecological health(IEH) scores, based on the chemical, physical, and biological parameters, were low compared to the 45 reference streams due to physical and chemical disturbances of massive constructions of the residential and commercial complex. This stream, thus showed a tendency of typical urban streams which are disturbed in the chemical water quality, habitat structures, and biological integrity. Effective stream management plans and restoration strategies are required in this urban stream for improving integrative stream health.

This study was conducted to investigate the awareness tendency of the government employees who manage forest roads about problems of forest road use and how to improve them in the future using surveys. The results show there are more silvicultural operations than harvesting operations using forest roads. The main purpose of using forest roads is to transport workers; however, the road will be used more for harvesting operations in the future. The respondents wanted to be accessibility for forest operations within 200 m from road in both present and future. For silvicultural operations 1-ton vehicle is used at present, and 5-ton vehicles are expected to be used in the future. For harvesting operations 5-ton vehicle is used at present, and 10-ton vehicles are will be used in the future. The roadway width is 3 - 4 m at present, but should be 4 - 4.5 m in the future. The longitudinal gradient of roads is 7 - 10% at present, and will be below 10% in the future. The minimum curve radius of roads is 12 - 15 m at present, and will be 15 - 20 m in the future. The results provide basic data for making future forest road policies.

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.

Purpose: The aim of this study is to identify factors of Korean female workers' childbirth plans and to establish measures to improve the childbirth plan. Methods: Study subjects were selected part in the 1st, 3rd, and 5th year surveys of the Korean Longitudinal Panel Survey of Women and Families. The selection criteria were as follows: women who had a spouse; were salaried workers currently employed for the last one month; belonged to a childbearing age; and had less than 3 children. Logistic regression analysis was conducted to investigate factors associated with childbirth plans. Results: Childbirth plans by female workers decreased each year. The analysis of associated factors revealed that age, number of children were associated factors in all years. In addition, education, satisfaction about dividing household chores with the husband, and satisfaction about working environment were associated with the lack of planning for childbirth in female workers in the 1st survey year. Satisfaction about dividing household chores with the husband, family-work conflict, and satisfaction about the potential for personal development were associated factors in the 3rd survey year. Finally, family-work conflict, satisfaction about employment stability, and satisfaction about job task at work were associated factors in the 5th survey year. Conclusion: It is important to know the measures focusing on the lack of planning for childbirth, and hence these factors can be improved by assessing in general, family, and occupational characteristics. Additionally, employer policies regarding women employees who are pregnant or have children at home need to be reviewed.

Purpose: The purpose of this study was to describe changes in positive psychological capital, organizational commitment and burnout according to work periods for new nurses. Methods: A longitudinal study was done using surveys of 91 nurses from a tertiary hospital located in Seoul, South Korea. Data were collected from these newly graduated nurses during the period from July 2018 to September 2019, three times (2 months, 4 months and 6 months after starting to work). Results: Hope of positive psychological capital decreased after 6 months of work (F=7.11, p=.001) and organizational commitment decreased after 4 months of work (F=15.30, p<.001). Factors influencing participants' burnout included the optimism of positive psychological capital and continuance of organizational commitment. These factors explained 51.3% of the variance in burnout (F=48.47, p<.001). Conclusion: Organizational support for new nurses is urgently needed. It is necessary to develop programs to strengthen the positive psychological capital of newly graduated nurses to reduce their burnout and to help their job adaptation.

Purpose: This study aimed to investigate the association of social participation and depressive symptoms with health-related quality of life (HRQoL) among older adults living in urban and rural areas. Methods: This secondary, cross-sectional study was conducted with a total of 66,765 adults aged ≥65 years (urban-26,485 and rural-40,280) who participated in the household and individual surveys of the Korea Community Health Survey 2019. Data on the main study variables including social participation, depressive symptoms, and HRQoL were collected from August 16 to October 31, 2019. Multiple linear regression was used to identify the factors affecting HRQoL in urban and rural older adults. Results: The proportion of social participation (χ²=354.69, p<.001) and the level of HRQoL (χ²=12.06, p<.001) were significantly higher in older adults living in urban area than those in rural area. However, there was no significant difference in depressive symptoms between older adults living in urban and rural areas. Multiple linear regression analysis showed that social participation and depressive symptoms were significant predictors of HRQoL in both urban and rural older adults. Conclusion: Our main finding highlights that active participation in social activities and management of depressive symptoms in older adults regardless of living arrangements are crucial to improve HRQoL in later life. Interventions to increase social participation include early assessment of depressive symptoms in the community to promote HRQoL. More longitudinal studies are needed to identify the factors associated with HRQoL between older adults living in urban and rural areas while considering neighborhood environment and living arrangements.

Objectives: This longitudinal study was done to identify the relationship of school adjustment and sponsor support or future time perspective and the differences of these 3 variables between 1st and 2nd survey of children having Didimseed account in institutional care. Methods: Participants were 25 elementary fourth to sixth grade children who are living on one facility that located in G. metropolitan area at 1st survey and 2nd survey was done at five-year intervals. Data were collected from September 2012 to September 2017 and were analyzed using t-test, paired t-test, ANOVA, post-hoc test and Pearson's correlation coefficients. Results: The level of school adjustment knowledge was not different significantly according to grade, gender and admission period at 1st survey. At 2nd survey, the level of school adjustment was different significantly according to grade only. The level of school adjustment was associated with positive future time perspective(r=.74) and negative future time perspective(r=-.54) at 1st survey, and that was associated with negative future time perspective(r=-.49) and meeting frequency of sponsor(r=-.43) at 2nd survey. There were not significantly different school adjustment and future time perspective variables between both surveys. But meeting frequency of sponsor at 2nd survey was lower significantly than that at 1st survey. Conclusions: Based on the results of this study, it would be necessary to prepare the policies that could have their positive future time perspective to increase school adjustment of institutionalized children. Also the effective strategies to increase not only Didimseed account support but emotional support through qualified meeting with sponsors should be developed.

Background: The turnover rate of nurse aides in Taiwan is high. However, the predictors of turnover behavior in the newly employed are still unclear. Objective: To examine the predictors of turnover behavior in newly employed licensed nurse aides. Methods: A longitudinal study design was used and subjects were newly employed certified nurse aides from a nurse aid training association in Taiwan. A total of five questionnaire surveys were conducted. The questionnaire was mainly used to collect information on turnover behavior, personal socioeconomic background, workplace psychosocial hazards, worker health hazards, and musculoskeletal disorders. Results: A total of 300 participants were recruited in the study. Cox regression analysis results showed that short working experience (hazard ratio [HR] = 0.21, p < 0.01), work as non-home nurse aides (HR = 0.58, p = 0.01), low monthly salary (HR = 0.68, p < 0.01), high work mental load (HR = 1.01, p = 0.01), low workplace justice (HR = 0.97, p < 0.01), high workplace violence (HR = 1.60, p < 0.01), high burnout (HR = 1.01, p = 0.04), poor mental health (HR = 1.06, p = 0.04), and high total number of musculoskeletal disorder sites (HR = 1.08, p = 0.01) contribute to a higher risk of turnover. Conclusion: The results indicated that employment period, work as a home nurse aide, monthly salary, work mental load, workplace justice, workplace violence, work-related burnout, mental health, and total number of musculoskeletal disorder sites are predictors of turnover behavior in newly employed certified nurse aides.
