  • The authors developed 28 needs assessment tools for integrated assessment centered on needs, which is the core element in care management for the elderly in home. Also, the authors collected the assessment data of 676 elderly persons in home from 120 centers under the Korea Association of Senior Welfare Centers by using the needs assessment tools, and finally developed needs extraction algorithm through decision tree analysis in data mining to identify their actual needs and provide social welfare service suitable for such needs. The needs extraction algorithm for 28 needs of the elderly in home are summarized in

    . The Need No. 8 "Having need of help in going out" of the decision-making model, for example, was divided into 80.3% of asking for help and 11.4% not asking for help with Appeal No. 23 as a major variable. The need increased by 87.9% when the elderly appealed for help to go out and they had a caregiver but decreased by 47.4% when they had no caregiver. When the elderly asked for help in going out, they had a caregiver, and they needed complete help in cleaning, their need of help in going out was shown as 94.2%. However, seen from their answer that they needed complete help in bathing of ADL even if they did not ask for help in going out, it was found that the need of help in going out sharply increased from 11.4% to 80.0%. On the other hand, when they needed partial help or self-supported in bathing, the potential for them to be classified as asking for help in going out was shown to be low as 7.7%. In the said decision-making model, the number of cases for parent node and child node was designated as 50 and 25, respectively, with level 5 of the maximum tree depth as stopping rule. By this, it was shown that their decision-making was found to be effective as 182.13% for the need "Having need of help in going out". The algorithm presented in this study can be useful as systematic and scientific fundamental data in assessment of needs of the elderly in home.

    • This study was carried out to investigate the factors of food service satisfaction of the elderly in Busan. The survey was conducted from September 1 to October 15, 2009 by questionnaires and data analyzed by SPSS program. Fifty point nine percent of the subjects lived alone and the source of living expenses of 70.5% of the subjects was subsidy from government. The most important reason for the elderly to participate in meal service was 'economic difficulty' and 'to meet friend'. The subjects had various chronic degenerative diseases, such as arthritis, hypertension, diabetes, osteoporosis and cardiac disease. Sixty-six point eight percent of the subjects needed diet therapy for their diseases, but 87.1% of them don't want to pay the extra fee. Thirty six point five percent of the subjects attained information about lunch program because it was 'close to home' but 20.7% was 'from public officials'. The reasons for the use of the meal service were 'economic difficulty' (40.0%), 'to meet friends' (22.6%), and 'bother to prepare meal' (16.50%). The services provided by welfare center were health care, physical exam and haircut. The score given by the subjects on the satisfaction of meal service was 3.84 on the 5-point maximum scale. Higher satisfaction on kindness of staff, satisfaction of social support and awareness of support resulted in higher satisfaction of food service. It would be effective to provide food service models that meet specific needs of the elderly according to social welfare service and social community activities.

    • This study is designed to find out the determinants of housewives' caregiving behavior to their elderly parents-in-law. For this purpose, a tentative path model, constructed with major socio-demographic variables in the caregiver's family as exogenous variables, is proposed to account for caregiver's behavior to elderly parents-in-law. The model is estimated with data collected from a probability sample of housewives in Kwangju, Korea. Estimation of the model, separately for caregiver's fathers-in-law and mothers-in-law, in terms of maximum likelihood(ML) procedures in LISREL8 reveals that housewives' educational attainment, father-in-law's age, father-in-law's health status, and family size have statistically significant causal. effects on care giving behavior to fathers-in-law, and that housewives' educational attainment, mother-in-law's age, family size, and caregiving attitude have significant causal effects on caregiving behavior to mothers-in-law. Comparison of the two estimated models indicates caregiver's educational attainment, caretaker's age, and family size are prominent determinants of caregiving behavior that can be commonly generalized to the two models. Except for these common determinants, however, a nonnegligible amount of differences is identified between the two models. The findings are discussed and interpreted with suggesting some salient theoretical and policy implications.

    • This paper has the objectives to define the concept of 'Good Care' which is the service goal we are aiming essentially for the improvement of long-term care service quality, to find out the components for 'Good Care', and to explore the conditions that create a good care. In addition, we tried to find the answer about what is the best way to measure the service quality. For this, I referred the advanced researches which explored the fundamental properties of care and tried to find the answer from the accumulated wisdom of service field through the 5-year long term care service experience. As a result of research, the good care can be defined as helping someone to be able to maintain his own life as maximum as possible with the goal to assure total quality life. The most important condition for good care is making 'a good care relationship'. Without damaging the relationship between care provider and care receiver, the individualized service focusing on the demand of care receiver based on mutual reliability, mutual respect and smooth communication should be provided. For the evaluation system, it is reasonable to set the standard according to the size of each institution for the core quality of facility service and establish the certification system of absolute standard to carry out the quantitative evaluation rather than the relative evaluation in the whole. For the part over the absolute certification standard, it is reasonable for each institution to characterize its own characteristics autonomously and carry out the qualitative evaluation for this. For the evaluation of home visit care service, it is recommended to contain the evaluation contents such as user satisfaction, satisfaction of care worker, how well the case management system of home care service center is operated etc.

    • Typically the standard optimal allocation method distributes the sample for each stratum considering survey cost. In case of varying survey cost for each survey unit, we need to consider more practical allocation method. In other words, according to characteristics of an individual unit, we consider the optimal dynamic allocation method which first selects the survey unit having maximum value of benefit cost ratio. In terms of this, the proposed allocation method is different from standard optimal allocation method which allocate samples for each stratum and selects the random sample according to each size of sample. This paper is considered the dynamic optimal allocation method for the stratified randomized response technique which surveys for sensitive characteristic of survey units such as drug abuse, abortion, alcoholic. We prove the practical usefulness of proposed method using the numerical example.

    • It will prove that with a more plausible specification of the relationship between income and the value of leisure, we can develop a more accurate model of the labor market without necessarily losing the primary merit of the received model. Moreover, with an improved understanding of labor market dynamic we can see that progressive era labor market legislation, designed to mitigate the effects of bargaining power inequality in low wage labor markets, was in fact based upon sensible economic foundations. The results of this study as follow; These low-wage dynamics present an example of a positive feedback system or "vicious circle" at work in the economy. With the revised labor supply schedule presented above, the market dynamic of the low wage sector push the wage away from the range that is consistent with a self-regulating market.

    • The aim of this study was to construct and test a structural equation model for the risk factors of metabolic syndrome in Korean adults. The structural equation model hypothesizes that eating alone and feeling depressed is a risk factor for metabolic syndrome. The data of this study were obtained from the Sixth Korea National Health and Nutrition Examination Survey which was cross-sectional data from the representative national survey. A total of 4,013 subjects replied to the survey item of lifestyle and completed the physical examinations among adults aged 19 years or older in South Korea was in 2015. The structural model in this study was composed of four latent variables: eating alone, depression, negative health behavior, and metabolic syndrome. Two variables, the rate of eating alone and depression, were exogenous variables. Negative health behavior was both a mediating variable and endogenous variable, and metabolic syndrome was the final endogenous variable. The data were analyzed using the Maximum Likelihood method and bootstrapping. The structural model was appropriate for the data based on the model fit indices. The results of this study can be summarized as follows: Eating alone is a direct risk factor of metabolic syndrome in Korean women. Depression can mediate metabolic syndrome through negative health behaviors. Negative health behavior had a direct impact on metabolic syndrome in both men and women. This study may be a guideline for interventions and strategies to reduce the incidence of metabolic syndrome in Korean adults.
