This study aims to explore the utilizing experience of public support service of the single mothers, who have been assessed as inability in aspect of labor. For this purpose of this study, we had in-depth interview five interviewees who had adolescent children or non-adult children. The participants were from 20s to 50s. From the outcomes of this study, we figured out that they had attempted to escape from the poor realities of life and to help the family budget through their work. However, they could not have plans to fulfill their aims, because of the unhealthy body conditions, the high working costs, the burdens for parenting or child-rearing, and the low levels of working ability. It has been shown that their parenting stresses and depressions from their hard realities have been reinforced, and those psycho-emotional pressures have been projected to connect with the inappropriate disciplines and parenting or child-rearing. And it has been reinforced through utilizing public support service. Consequently, they have become chronic through the repeated disappointment and unhealthy psycho-emotional condition. In this study, we discussed and proposed the labor policies and practical suggestions which have had a close relationship with the efficient judgement systems for work inability.

The Earned Income Tax Credit (EITC) is a policy that supports low-income households financially as well as provides an economic incentive to participate in the labor market. Thus, estimating the causal effect of the policy on the labor force participation rate of low-income households is critical for the policy evaluation. In this paper, we exploit the variation in the eligibility to the EITC and the size of the benefit over several reforms of the EITC in South Korea since 2008 and estimate the impact on the participation in the labor market. Using data from four major household surveys, we find that the results are mixed; in some samples and specifications, we find that the effect is positive and statistically significant, while it is insignificant in others. The estimated effect is more likely to be positive and significant when we restrict the sample to the period before 2014. It is an important topic of future research whether the EITC's effect gets weaker because it is extended to cover the self-employed and beneficiaries of the National Basic Livelihood Security.

최근 식생활의 서구화로 인해 기호식품의 사용량이 증가하고 설탕섭취량은 계속적인 증가를 보이고 있다. 특히, 아동들이 우리의 전통식생활에서 멀어지고 단 맛 위주의 스낵류나 과자 케일 등과 같은 기호식품의 사용으로 인한 설탕섭취량이 증가하고 있다. "식품수급표"상에 나타난 설탕공급량을 위주로 우리 국민의 설탕소비패턴과 국제간 비교를 통해 한국인들의 설탕섭취수준이 어느 정도인지를 파악하고 단맛에 대한 한국인의 기호도의 변화과정을 살펴보았다. "2001 국민건강영양조사"에서는 한국 성인 1일 1인당 약 60 g 정도의 설탕 섭취량을 보였다. 농림부의 "식품수급표"를 중심으로 살펴보면 2002년에 1인 1일당 설탕공급량이 57 g으로 나타나 미국인의 1일 설탕섭취량인 130 g 정도인 것에 비하면 아직도 적다고 볼 수 있다. 그러나 1962년에 4.8 g이었던 것을 생각하면 상당히 증가하였다. 식품수급표상에 나타난 국제 통계 비교치에서는 한국인의 1일 설탕공급량을 99g 으로 잡고 있어 실제로는 한국인들의 설탕섭취량이 상당한 수준으로 올라왔음을 짐작케 한다. ISO의 국제 비교에서는 1년 1인 소비량이 22.7kg으로 전 세계 국가 평균 소비량을 상회하고 있다. 아동의 가공식품 소비로 인한 설탕섭취량은 급속히 증가하였고, 현재 급속히 증가하고 있는 아동비만 현상과도 관련이 있다. 1995년에 행해진 초등학생들의 설탕섭취실태자료를 통해 볼 때 이미 10년 전에도 도시지역이 아닌 농촌 지역 아동의 설탕섭취량이 이미 60 g 이상을 넘어서고 있었고 급원식품에서 성인들이 주로 과일류 의존이 높았던 반면 아동들은 간식류에서의 설탕섭취가 매우 높았다. 따라서 연령별로 매우 자세한 간식 목록에 의거한 설탕섭취량 조사가 무엇보다도 필요하다. 현재 한국의 식품성분표에는 다양한 한국음식에 대한 설탕함량 Database가 없으므로 미국의 USDA Database를 기초로 한국 식품의 설탕 함량을 추론해야 하는 어려움이 있다. 따라서 다양한 한국음식의 설탕함유량에 대한 Database구축이 무엇보다도 필요하다고 보인다.

This paper analyses the Night Thermal-storage Power Service(NTPS) from the perspective of sustainability. It investigates the economic, environmental and social aspects of NTPS, thereby reveals that NTPS triggers the inefficient use of fuel, the increase of carbon dioxide emission and the increase of cross subsidy between consumers. This paper also analyses NTPS from the perspective of energy security. It investigates how NTPS makes LNG demand volatile in winter, thus threatens our energy security. According to the analysis, NTPS directly violates two basic principles of national energy policy; Sustainability and Energy Security. To solve these problems, not only the harmonized adjustment of Heating Oil Tax and Electric Power Rates is needed to curb the rapier increase of NTPS, but also another separate policy is necessary for converting the electric heating system based on NTPS into the one based on Heating Oil.

The National Basic Livelihood Security(NBLS) System implemented from October 2000 has expanded cash assistance to cover the poor who are able to work in our country. Although the cash assistance for them has positive aspects of providing basic livelihood security for all people, but many scholars have also pointed out its negative aspects such as a decrease in labor supply among the poor. In order to provide policy implications for the cash assistance program of our country as well as the US, this paper examines the impact of Temporary Assistance for Needy Families(TANF) on poverty among single mothers and their families using data from March Current Population Survey of $1991{\sim}2002$. TANF imposes strong work requirements and time limits to recipients as conditions for cash assistance, which are major sub-components of TANF. Therefore, this paper analyzes TANF by looking at work requirements and time limits separately, not by looking at TANF as a single policy. The research findings show that work requirements significantly decreased income and increased poverty among single mothers. Although time limits show income increasing effects and poverty decreasing effects, it seems further studies on time limits are needed at this point. The research findings of this paper provide important lessons for welfare to work cash assistance of our country as well as the US.

This study examines the problematic fact that most housewives are excluded from receiving the benefits of the National Pension Plan in South Korea. The National Pension Plan assigns no value to housework or household production, which in turn discourages full-time housewives from participating voluntarily in the Plan. In this article, I propose to utilize Credit Splitting and Pension Sharing in order to take into account full-time housewives' economic contribution in the National Pension Plan. In this article, I also discuss the ranges and application methods of the Credit Splitting and Pension Sharing. For this study, I have analyzed the data of 11,967 unemployed married women living with spouses published in“Research Data on Everyday Life Time Usage”by the Korea National Statistical Office in 1999. The value of the full-time housewives' labor varies depending on the methods of estimation. However, all estimated values exceed the average value assigned to the housewives by the National Pension Corporation. It is clear that full-time housewives' unpaid labor contributes a great deal to the formation of household property and wealth, which is a valid reason for Pension Sharing and Credit Splitting. This article also provides logical factors to consider in the process of Pension Sharing and Credit Splitting, which can be used for developing computerized software to determine a full-time housewives' labor value at the time of divorce or for any other purpose.

The purpose of this study is to identify physical activity levels of the basic livelihood security recipients elderly women, to investigate relation between cardiovascular disease risk factors and sacrcopenia based on the levels, and to develop physical activity programs for healthy life of the elderly. The subjects of this study were 134 old females with $71{\pm}6.67$ years old who used senior centers in K-gu. The authors used the International Physical Activity Questionnaire for investigating the physical activity levels of the elderly, measuring their physical activity levels for seven days on average and classifying them into two groups, the Low Physical Activity (n=77) and the Moderate Physical Activity (n=57) groups based on the levels. Blood pressure, waist measurement, TC, HDL-C, LDL-C, TG, Glucose, and atherogenic index (AI) were measured as the cardiovascular disease risk factors; percent body fat, appendicular skeletal muscle mass, total muscle mass, and skeletal muscle index were measured as factors related to sarcopenia. Independent samples t-Test was conducted to analyze differences on the two groups based on the physical activity levels, with ${\alpha}=.05$ the as significance level. According to the results, HDL (p=.017) were higher and AI (p=.007) was lower; percent body fat (p=.008) was lower, and ASM (p=.000), total muscle mass (p=.000), and SMI (p=.001) were higher. In conclusion, moderate intensity physical activities rather than low intensity ones may have positive effects on the cardiovascular disease risk factors and sarcopenia levels, and participation in regular physical activities with at least moderate intensity by various methods may be needed for prevention of illness and healthy life of the elderly.

지구환경문제와 에너지 수급관계를 감안할 때, 청정 및 대체에너지 연구개발은 불가피하며, 그 중에서도 태양에너지는 대표적인 대안의 하나로 인식된다. 따라서 태양에너지의 적극적인 활용에 필요한 기초자료의 마련은 필수적이다. 태양에너지의 이용 및 관련 절약 기술에 필요한 태양에너지 자원(기상)에 대한 기술자료는 최소한 30년간의 측정 자료를 필요로 한다. 이들 자료에는 시간별 수평면전 일사량, 법선면 직달일사량 및 수평면 산란일사량은 물론 시간별 평균치로 운량, 기온, 습도 등이 포함된다. 이들 자료로부터 자료의 분포, 평균 및 최고, 최저값 등과 같은 기초자료들을 선별하여 관련 시스템 설계에서 요구하는 기준을 충족하여야 하는 것이다. 그러나 우리나라의 경우, 태양에너지 자원에 대한 정밀한 측정은 1982년 이후 수평면 전일사량, 1990년 이후에서나 법선면 직달일사량에 대하여 본격적으로 이루어진 실정으로, 자료의 표준화 및 신뢰성 확보에는 여전히 상당한 시간과 노력이 요구되는 실정이다. 지속적인 측정과 더불어 요구되는 것으로 측정자료의 가공기술을 들 수 있다. 즉, 측정자료의 품질평가 및 관리 기술, 미측정 또는 불량자료의 복원 기술 및 측정 지역외 자료의 추정을 위한 보간기술 등이다. 이와 같은 기초자료 및 기술에 관한 연구개발은 보다 구체적인 적용에 앞서 필수적으로 이루어져야 할 과제이다.

Present status on the pesticides production, supply, manufacture and pests control in Korea are summarized. The data in the past several years (1971-76) are analyzed to find out the problems and solutions for the further development of plant protection and pesticide industry in Korea. Since the acreages of crop plantation and the quantities of pesticides uses are already near to the stage of plateau, pesticide formulation with imported technical grade should be modified by local synthesis with imported quality. The government pesticides management act and regulations must be modernized urgently in connection with the synthesis. formulation, tests, registration, quality control. price and supply system as well as the safety use of pesticides. Recommendation concerning acceptable daily intakes(ADI) and residue limits must be established for the strengthning pesticide safety use and plant protection activities as soon as possible. The use of fungicide-insectide mixture in dust formulation must be authorized and practiced immediately for the labor saving and one-hit cooperative mass control of rice disease and insect pests, especially. At present, serious considerations on pesticide safety use and integrated pest control are strongly urged to help the farmers, to save the industries and to keep the nature as it is required.
