  • Korean groundwater quality standards were established in 1994, and revised in 2003 and 2010. The substances for which standards have been developed are classified into two groups, general pollutants, 4, and specific pollutants, 15. The standards have been applied to household water use, agriculture, aquaculture, and industrial use. However, there is no systematic methodology for either selecting candidate substances or establishing groundwater standards. We investigated various derivation methodologies for groundwater standards used by the European Commission and 27 member states and compared their methods for determining threshold values. The European Commission presented to their member states groundwater standards for two substances and a list of required substances for derivation of threshold values along with the member states. Interestingly, they first considered national background levels and then considered other criteria for water protection, such as drinking water standards, environmental quality standards, and irrigation standards. We suggest that Korean background levels in groundwater should be included in the methodology for establishing groundwater quality standards. These results may be useful in developing a systematic methodology for establishing Korean groundwater quality standards.

  • BACKGROUND/OBJECTIVES: Folic acid supplementation before pregnancy is known to significantly reduce the risk of having a baby with neural tube defects (NTDs). Therefore, it is important for women to be aware of the effects of folic acid supplementation before pregnancy. The purpose of this study was to investigate the awareness and preconceptional use of folic acid and to assess the current knowledge about folic acid among low-income pregnant women in Korea. SUBJECTS/METHODS: A questionnaire survey was conducted in 2012. Five hundred pregnant women were selected from the waiting list for the Nutriplus program implemented in public health centers using a multistage clustered probability sampling design. Data from 439 women were analyzed after excluding ones with incomplete answers. RESULTS: Among women who responded to the questionnaire, 65.6% had heard of folic acid before pregnancy, and 26.4% reported on the preconceptional use of folic acid. Women with a university degree or higher education were more likely to be aware of folic acid and to take folic acid in the preconception period. In a multivariate logistic regression, when age, education level, household income, employment status, gravidity, parity, and folic acid awareness were included in the model, folic acid awareness was a strong predictor of preconceptional folic acid use. As of interview, 85.4% and 77.7% of women were aware of the NTD-preventive role of folic acid and the appropriate time to take folic acid, respectively. The main sources of information on folic acid were healthcare professionals (41.2%), friends and family members (31.2%), and the media (26.5%). CONCLUSIONS: Our results suggest that public health strategies are needed to increase the preconceptional use of folic acid among Korean women.

  • Objectives: This study explored the community food environmental factors affecting food purchasing using a qualitative research methodology for the elderly as well as the various food environments under their socioeconomic diversity. Methods: For the qualitative data collection, this study interviewed 20 elderly people aged 65 years or more, who participated in a public health program or lunch services operated by the senior welfare center in Seoul. Five dimensions, such as availability, physical accessibility, affordability, acceptability, and accommodation suggested in previous studies, were used to identify the community food environmental factors. Results: The elderly participants showed overall similarities to the concepts derived from existing studies on the five dimensions of food accessibility environment. In addition, other important food accessibility environmental factors that were not present in previous studies, such as acceptability for a product of domestic origin, delivery service to home, and small-packaged food sales, were derived. On the other hand, the concept of some subjects differed depending on the household income and specifically for the physical accessibility concept. This showed that the close distance factor from a grocery store at home might not apply to older adults in low-income households in Korea. Conclusions: This study found that five dimensions of the food environment suggested by previous studies could also be applied to vulnerable older adults in Korea. On the other hand, the socioeconomic characteristics of individuals and households would affect the perspectives of their local food environments differently. The findings of this study could help in the development of tools for evaluating the community food environment.

  • Journal of the Korean Society of Clothing and Textiles Vol. 19, No. 1 (199i) p. 71~79 The authors study on the traditional textile production and the formal dress through the field research concerning the folk attitude toward dress style around the Mt. Kumo area. In this area, people produced and wove hemp, cotton, and silk except ramie. Because of poor production of raw materials, they produced textiles only for self-sufficiency. Every household dealt with dyeing on a small scale. In the past, people dyed cloth natually using plants as material. Natural dyeing, however, gradually changed into chemical one since the Japanese rule. The formal dresses, which people wore on particular occasions such as the hundredth day after child's brith, the first birthday, and traditional holidays, were very meager due to poor living standards. People could not see the formal dresses with full decoration. Bride and bridegroom were the village.owned wedding dresses, and if they could not afford to, they simply put cloth on to remember the occasion. People around the Mt. Kumo area, however, provided fully-decorated shroud and ritual robes to the level of other better-off areas. It seemed to be the result of influence of deep-rooted Confucianism in Gyungbuk province. This Phenomenon could be found in the folk dress style in other regions as well as the Mt. Kumo area in Gyungbuk province.

  • This study investigates the impact of International Monetary Fund(IMF) Age on the household behavior of food consumption and analysis the related factors(demographic variables, family life style) to find out the reasonable consumer's consciousness and food market conditions. The results are as follows. 1. General life style and food life style, considered as family life style, were classified into 7 types and 9 types respectively as family life style by factor analysis. 2. The rationality of using and disposing stage on food life has increased, the rationality of the planning stage on food life has decreased since the IMF age began. But the rationality of overall food consumption has hardly changed. 3. The amount of purchasing was decreased, discount store was favorite place to buy food, and safety and freshness were major determinants in purchasing for most of food items. But this was different with food items. The various information sources were used impartially to buy food, cash was used mainly, and the degree of using the discount ticket/coupon was a little low. 4. Income level is an influential factor on the rationality of the planning and purchasing stage on food life, while environment-oriented food life style has influenced on the rationality of using and disposing stage. The purchasing amount of grain products, meats, milk products, bread and snacks, drinks, alcoholic drinks, water and convenience goods has influenced by demographic variables, eating out had been influenced by general life styles, and fruits, healthy foods, processed foodstuffs, favorite foods, vegetables seaweeds, import foods and seafood had been mainly influenced by food life style since IMF age began.

  • Public expenditures on long-term care are a matter of concern for Korea as in many other countries. The expenditure is expected to accelerate and to put pressure on public budgets, adding to that arising from insufficient retirement schemes and other forms of social spending. This study tried to foresee how much health care spending could increase in the future considering demographic and non-demographic factors as the drivers of expenditure. Previous projections of future long-term expenditure were mainly based on a given relation between spending and age structure. However, although demographic factors will surely put upward pressure on long-term care costs, other non-demographic factors, such as labor cost increase and availability of informal care, should be taken into account as well. Also, the possibility of dynamic link between health status and longevity gains needs to be considered. The model in this study is cell-base and consists of three main parts. The first part estimated the numbers of elderly people with different levels of health status by age group, gender, household type. The second part estimated the levels of long-term care services required, by attaching a probability of receiving long-term care services to each cell using from the sample from current year. The third part of the model estimated long-term care expenditure, along the demographic and non-demographic factors' change in various scenarios. Public spending on long-term care could rise from the current level of 0.2~0.3% of GDP to around 0.44~2.30% by 2040.

  • Purpose: Fatigue is a common problem in Parkinson's disease (PD), affecting 30~65% of patients with that diagnosis. Only recently has fatigue been recognized as an important clinical feature of PD. The aim of this study was to investigate the level of fatigue and related factors in patients with PD. Methods: Between March 1, and September, 30, 2010, a sample of 181 PD patients agreed to be interviewed. Results: The female patients' PFS (Parkinson Fatigue Scale) score was higher than those of the male patients. Household income and having a Job were significantly correlated with the PFS scores. Among the disease characteristics, motor fluctuations, dyskinesia and modified Hoehn and Yahr stage were significantly correlated with the PFS scores. On stepwise regression analysis, the most important factors related to the PFS scores were depression and sleep disturbance. Conclusion: Fatigue in patients with PD was associated with many factors and strongly associated with depression and sleep disturbance. Fatigue is a multidimensional construct; therefore, multidimensional strategies for relieving specific aspects of fatigue are needed.
