The purpose of this study is to investigate the correlation among the stroke patient family's health, burden and quality of life which is based upon the comparative appreciation of the adult stroke patient's family and elderly stroke patient's family. For this purpose, data were collected from the family care-givers for two groups of stroke patients under sixty years old and over sixty years of age, admitted at K Hospital and H Hospital in Seoul. The instruments for this research are based on the tool for measuring physical health and psychological health developed by Yang, Young-hee(1992), the tool for measuring the sense of burden by Seo, Mee-hae and Oh, Ga-sil(1993), and the tool for the quality of life by Noh, Yoo-ja(1988). The sampling for this study was done from December, 2000 until February, 2001. Questionnaire data were drawn up by personal interviews aided by the staff nurses. The analysis of collected data are based on general characteristics calculated at the rate of 100 percent of the average, t-test, ANOVA(some difference on a level with p<.05 being subsquently confirmed by DMR) for Health Status, Burden, Quality of Life and Pearson Correlation to verify the hypothetical correlation among the subjects. The results of this study are as follows: 1. In the adult stroke patient family, the factors influencing the physical health proved to be age, present occupation and family-formation. Here, the factors influencing psychological health turned out to be age, matrimonial status, present occupation and family-formation. In the elderly stroke patient family, the factors influencing physical health proved to be age, gender, final academic status, matrimonial status, present occupation, and relation with the patient. Here, the factors influencing the psychological health were age, final academic status, matrimonial status, present occupation, relation with the patient and family-formation. In the former case, the influencing factors upon the burden were shown to be age, final academic status, matrimonial status, relation with the patient and family-formation. In the latter case, the influences upon the burden were age, gender, final academic status, matrimonial status, present occupation and relation with the patient. In the former case, the influences on the quality of life were gender, and economic situation. In the later case, the influencing factors on the quality of life were age, final academic status, matrimonial status, present occupation, and relation with the patient. 2. The rate of the physical condition in the former case turned out to be 2.83, and the psychological condition 2.37. The physical condition of the latter case was 2.76, and the psychological condition 2.46. The rate of the burden in the former case was 3.14, and that of the latter case was 3.04. The rate of quality of life in the former case proved to be 2.46, and that of the latter case 2.55. 3. The rate of correlation between the burden and the quality of life appeared to be the high counter-correlation (r= -.573). The rate of correlation between the psychological health and the burden of a simialr (r= -.565). The rate of correlation between the physical health and the psychological health proved to be a moderate correlation (r= .372), The rate of correlation between physical health and the burden turned out to be a low counter-correlation (r= -.276). According to this study, there proved to be a very close correlation among the stroke patient family's health, the burden and quality of life. Thus, it would be necessary to find out various nursing interventions in order to mitigate the stroke patient family's burden in the process of caring for the patients.

One of many factors that influences the profit of an enterprise is the amount of the stock in an enterprise. When the stock amounts are optimal the economic burden of the enterprise decreases which in turn results in the optimum number of employment and spatial utilization of storages. The purpose of this study is the simulation modeling of a material stock control system using DEVS models in order to get the most suitable stock amounts. The stock within an enterprise is built by the orders from outside world. The effect on the stock by the factors such as order, delivery, and production components has been analyzed based on simulation results.

본 연구는 현재 한국사회에서 급증하고 있는 조손가족의 성격과 경험의 다양성을 탐색해보는 연구의 일환으로 조손가족 조모들이 손자녀를 양육하면서 겪는 어려움(비용)과 더불어 긍정적 측면(보상)을 함께 탐색해보았다. 이에 조모의 양육 보상 및 비용 지각의 수준 차이를 살펴보며, 조모 및 손자녀 특성, 가구 특성, 정부의 지원이 조모의 보상 및 비용 지각에 미치는 영향력을 파악하였다. 또한 양육 보상-비용 지각의 유형화를 시도함과 아울러 각 유형집단이 가진 특성을 고찰하였다. 한명 이상의 18세 이하 손자녀와 동거하면서 주양육 책임을 지고 있는 조모 449명으로부터 수집한 자료를 분석한 결과, 우리나라 조손가족 조모는 양육에 대한 비용을 지각하는 것과 동시에 보상 또한 높은 수준에서 지각하는 것으로 나타났다. 양육 보상감을 종속변수로 한 위계적 다중회귀 분석 결과, 조모의 경제적 형편, 손자녀의 연령, 손자녀의 기질적 특성 등이 유의미한 영향을 미치며, 친족지위, 정부의 도구적 지원 등도 유의미한 영향력을 가지는 것으로 나타났다. 양육비용을 종속변수로 한 분석결과에서는 조모의 신체적 건강, 경제적 형편, 손자녀 수, 양육동기가 비용감에 유의미한 영향을 미치는 것으로 나타났다. 양육보상-비용 지각 수준을 기준으로 유형화 작업을 실시한 결과, 4개의 유형이 관찰되었으며 가장 많은 수의 응답자가 <보상고(高)-비용저(低)>집단에 속하는 것으로 나타났다. 이는 조손가족의 부정적 측면, 즉 높은 비용에 초점을 맞추는 기존 시각을 재검토할 필요성을 제기하는 결과라고 할 수 있으며, 조손가족 조모의 손자녀 양육경험이 다양한 양상임을 시사한다고 하겠다.

The Korean government announced a national mid-term target to reduce 30% of greenhouse gas (GHG) emissions from business-as usual (BAU) level by 2020 in a voluntary and independent manner. In this study, we examined the $CO_2$ mitigation potential and conducted an economic effect analysis of green living actions in households in Korea. We also proposed some ways to implement green life to achieve the national target. If green lifestyle takes root in households nationwide, $CO_2$ emission would be reduced to 27.3% of the emission in 2007. This would save the country about 4.93 trillion won per year and each household could save about 300,000 won per year, which accounts for about 0.5% of GDP (as of 2007). Considering the five-year plan for green growth to invest 2% of GDP in green growth every year, this would not only reduce the economic burden on households, industries and the country but also increase economic growth potential by reinvesting the saved resources into green growth. Heating and lighting would be the greatest contributor to GHG mitigation of green life in the residential sector. It means we could achieve the national goal by reducing unnecessary heating and lighting and using energy-saving electric home appliances. The implementation of green living actions would reduce a significant amount of greenhouse gas emissions, ultimately relieving the burden on businesses to reduce GHG emissions. And it is one of the most cost-effective mitigation tools in order to achieve the mid-term GHG mitigation goal.

The purpose of this study was to analyze the differences in the expenses of private education and the economic preparations for old age according to household income and consumption wants for education in mothers with school-aged children. The data used in this study were collected from 416 mothers with school-aged children aged 8 to 19 years old living in Daegu. The data analysis methods adopted for the study were two-way ANOVA and Scheff$\acute{e}$ test. The results of this study were as follows: First, there were differences in the private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of low household income, the mothers with high consumption wants for education spent more money on academic education and music, fine arts or physical education than the mother's with low consumption wants for education. On the other hand, in the group of mothers of high household income, the mothers with low consumption wants for education spent more money on academic education and spent less money on music, fine arts or physical education than the mothers with high consumption wants for education. There were no meaningful differences in the group of mothers of middle household income. Second, there were differences in the perceived burden of private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of middle household income, the mothers with low consumption wants for education perceived there was a higher burden for private education expenditure than the mothers with high consumption wants for education. Third, there were differences in the expenditure preparation for old age and the economic preparation behavior for old age according to the level of household income. The mothers with high household income spent more money on preparation for old age and did well in economic preparation behavior for old age than the mothers with middle and low household income.

The purpose of this study was to understand the meaning and nature of long term boarding care of children provided by grandparents in surrogate foster homes. Data were collected from 10 children 15 to 18 years of age by in depth interviews and observation from May 2007 to July 2007. Analysis of data was by the phenomenological analytic method of Giorgi(1970). Seven essential themes were extracted: (1) ambivalence about being labeled "family headed by a child," (2) recognition of the burden to grandparents with appreciation for their care, (3) resentment and yearning for parents, (4) economic hardship, (5) discord with grandparents, (6) maladjustment to school life, and (7) overcoming such obstacles as poor economic conditions and loneliness.

This study is to organize the frame of measuring inventory for housing quality related to mental health in foreign literature reviews. In the first step, many housing quality contents or items are extracted from empirical studies, including housing environment quality and mental health. In the next step, extracted contents and items are classified by space scope (house and neighborhood unit) and WHO housing properties (safety & security, health & sanitation, efficiency/convenience, comfort/amenity). Almost all housing properties follow the WHO standard, but some properties, sustainability and economic characteristics, do not follow the standard. These reflect on current Korean housing environment. They are energy saving and environment friendly effort, property value and economic burden, identity expression, and school district. So they need to be added to the Korean housing quality measurement related to mental health.

This article presents a new model called the periodic square wave(PSW) to describe the material flow of periodic processes involving an intermediate buffer. The material flows into and out of the intermediate buffer are assumed to be periodic square shaped. By using this model, It is proved that the classical economic lot size model with finite supply rate, the so-called EPQ model, can be applicable to the arbitrary periodic demand case. This new model relaxes the original assumption of the constant demand. It is shown, as a unique application example, that the explicit solution for determining both upstream and downstream economic lot size can be obtained with the aid of the PSW model. The PSW model provides more accurate information on analyzing the inventory and production system than the classical approach, without losing simplicity and increasing the computational burden.

Expanding product variety and high customer service provision place an enormous burden on demand forecasting and the matching of supply with demand in a supply chain. Postponement of product differentiation has been found to be powerful means to improve supply chain performance in the presence of increasing product variety. Delaying the point of product differentiation implies that the process would not commit the work-in-process into a particular finished product until a later point. This paper reviews the recent analytical models that quantify the value of delayed product differentiation. We conclude the literature review by summarizing and synthesizing the economic evaluation of the postponement and outline directions for future research.

Spinal cord injury (SCI) has a significant negative effect on the quality of life due to permanent neurologic damage and economic burden by continuous treatment and rehabilitation. However, determining the correct approach to ensure optimal clinical outcomes can be challenging and remains highly controversial. In particular, with the introduction of the concept of early decompression in brain pathology, the discussion of the timing of decompression in SCI has emerged. In addition to that, the concept of "time is spine" has been added recently, and the mortality and complications caused by SCI have been reduced by providing timely and professional treatment to patients. However, there are many difficulties in establishing international clinical guidelines for the timing of early decompression in SCI because policies for each country and medical institution differ according to the circumstances of medical infrastructure and economic conditions in the surgical treatment of SCI. Therefore, we aim to provide a current review of timing of early decompression in patient with SCI.
