Korean society is experiencing rapid changes which are certain to shape the lives of the older people and their families. So, the purpose of this study was to improve the quality of the elderly welfare service in Korea. Even though the interest about the elderly welfare in Korea is rapidly on the increase, the reality of Korean Society still leaves much to be desired, quantitatively as well as qualitatively. Pay attent to this point, now going to grasp the situation of not the handicapped elder people but the general elder people actual life condition and demand for welfare. So this study focused on the demand of not out-of home service but in-home care service. It was based on the data from by Korea National Statistical Office, having observed 6,139 elderly people. The results were as follows. They hope to get the elderly welfare services about health examination service, nursing survice, supporting service for household. That was, the most of them wanted in-home care service than out-of home care service. To ensure effective care to the elderly, it needed development and settlement of welfare service in face of their daily living. And, even though they recognized that they should cover the elderly life expenses themselves, the rate was hit that indicated their adult children as a parents supporter. This means that we should consider not only to the elder people but also to the family which contained the old people as the elderly welfare service. As a remedy, we can find the cooperation between elder welfare service at the social welfare organization and counsel, education at the family strengthen center. To improve the quality of the elderly welfare service in Korea, the elderly welfare service should focus not only on the physical and spiritual health maintenance but also active understanding living environment and growing ability to arbitrate between individual and living.

This study specifies daily behaviors that elderly residents perform in their living space and verifies the behaviors that they have difficulties in performing. The study categorized elderly people according to the level of difficulties they have when performing household activities (independence of behavior performance) and verified characteristics of the sub-behaviors and the level of difficulties of performing them in each type. For this purpose, the study conducted observation investigation on the behavior of elderly people by directly visiting houses of 52 elderly people over the age of 65. The characteristics of sub-behavior were also examined through photograph shooting and in-depth interview. In this study, behaviors of elderly people inside living space were categorized into the following nine behaviors. The study investigated the difficulties of performing these sub-behaviors according to the elderly people's level of independence by each behavior. Analyzing the difficulties of sub-behaviors according to the independence level, elderly people felt more structural problems and inconvenience in using facilities when they have lower independence level. Moving from independence to dependence, their performance of behaviors gradually became difficult, making them inevitable to use tools. At last, they came to need caregiver's help. For continuous sustenance of elderly people's independent living inside house, policy measures are required that can address the difficulties of sub-behaviors that are observed in a series of process of one's becoming dependent from independent in this study.

This study was conducted in order to investigate the factors affecting the elderly employment and especially focused on the factor of their residential areas. This paper performs binary logistic regression analysis with the micro data of 2014 Survey of Living Conditions and Welfare Needs of Older Koreans. To reveal the influence on the elderly employment, various dependent variables was used such as demographical, health, household, economic, lifelong job, living environment, and residential area characteristics. The elderly in rural areas have higher possibility of currently working than those in urban areas. Based on the results, more various and complex factors affected on the employment of the urban elderly. This suggested that differentiated policy supports were needed in the urban and rural areas.

Objectives: There are at least three conceptual models for the effects of the childhood social environment on adult health: the critical period model, the social mobility model, and the cumulative risk model. However, few studies have investigated all three different models within the same setting. This study aims to examine the impact of childhood and adulthood socioeconomic positions and intergenerational social mobility over the life course on the health in adulthood based both on the critical period model and the social mobility model. Methods: This study was conducted on 9583 adults aged between 25 and 64 years old and they were the respondents to the Korea Welfare Panel Study (2006). A multivariate logistic regression analysis was carried out, using the critical period model and the social mobility model out of the life course approaches, to look into the impact of childhood and adulthood socioeconomic positions and intergenerational social mobility on the health status in adulthood. Results: Household income and occupation out of the adulthood socioeconomic position indicators had an independent influence on the adulthood health status. The childhood socioeconomic position indicators, except for the place of childhood residence, affected the adulthood health status even after adjustment for the adulthood socioeconomic position. The effect of intergenerational social mobility was also statistically significant even after adjusting for the adulthood socioeconomic position, but it became insignificant when the childhood socioeconomic position was additionally adjusted for. Conclusions: Adulthood health is indeed affected by both the childhood and adulthood socioeconomic positions as well as intergenerational social mobility. This result shows that a life course approach needs to be adopted when dealing with health issues.

In the developing country, the transportation situation is changed very quickly and the transportation environment is not stable. So the transportation planning should be frequently made in considering the limited cost and time. And the traditional large-scale survey(household survey, roadside interview, etc.) has many Problem like the difficulty for doing it and getting mood results. Therefore the study about the method of evaluation on the traffic count based O/D matrix is Processing actively recently. Though the many study for the network in the realistic size are enacted, the study for comparing with the advantage and disadvantage of each method are few. Therefore this study mainly deals with the static method among the existing models of evaluation on the traffic count based O/D matrix(in terms of the transportation plan). Bi-level(GU) and gradient method are selected as main alternative model and analyzed their capability and validity. For testing the reliability of the models, Bi-level(GLS) and gradient method are adapted to toy network. Then we analyze the result of testing, and study the way for large network.

Recently as algae phenomenon has been intensified, the need for additional dam flushing has been raised. To establish the more rational policies concerning the dam flushing, it is necessary to evaluate the dam flushing. This paper attempts to examine households' willingness to pay (WTP) for dam flushing by using a contingent valuation (CV). Especially, unlike other CV studies which used maximum likelihood estimation (MLE), this study employed Bayesian approach. This study surveyed a randomly selected sample of 1,000 households nation-widely, and asked respondents questions in person-to-person interviews about how they would be willing to pay for the additional dam flushing. Respondents overall accepted the contingent market and were willing to contribute a significant amount (1,909.4 won), on average, per household per year. The aggregate value amounts to approximately 35.7 billion won per year.

Objectives : Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Methods : Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Results : Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Conclusions : Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

Smart grid technology can expand energy efficiency into the home by monitoring consumer energy usage in real time and communicating with household devices that respond to demands to shut off during periods of non-use, allowing individual consumers to control their electricity usage more effectively. But, the information collected on a smart grid will form a library of personal information, the mishandling of which could be highly invasive of consumer privacy. There will be major concerns if consumer-focused principles of transparency and control are not treated as essential design principles from beginning to end. In this paper, using. All-Or-Nothing Transform encryption mode for providing smart grid security, we propose efficient distributed data Management based on XOR operation. The contribution of this paper is to provide a secure algorithm that manages efficiently distributed data in the field of private data in smart grid environment.

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.
