This study examines individual determinants of hospital days in community-dwelling elders by estimating a linear structural equation model based upon Andersen's behavioral model. Data were collected through a national survey of elders in Korea in 1994. The subjects for this secondary data analysis were 1687 non-institutionalized elders aged 60 years or older. Except for the effect of age and gender on family help. the predisposing components had direct effects on the enabling components. Of the effects of the enabling components. family help had a direct effect on self-evaluated health; economic status had a direct effect on chronic disease and self-evaluated health; and access had a direct effect on chronic disease. functional health status and self-evaluated health. Of the enabling components. residence and family help directly affected hospital days. Self-evaluated health revealed the greatest direct effect on hospital days followed by functional health. Overall. the effects of the predisposing components and the enabling components on hospital days were not prominent. Since the model explained only $4\%$ of the variance in hospital days. the magnitude of the effect of the need components cannot be judged in terms of equity of distribution of health services. In particular. the effect of family help in the model reveals the importance of family support in health management of elders. The implications of these analyses for improving the proposed model of hospital days were discussed.

A multiobjective analysis technique was applied for the optimum operation of pumps and reservoirs in service water transmission systems. Three major objectives were identified and assessed on the normally operating service water transmission systems. They are, 1) stability of pump operation; 2) economic point of view in minimizing the energy cost for pumping; 3) reliability in meeting the stochasticaly varying demands. The measures of these objectives were required times of pump on-offs in stability, required total energy cost in economics, and minimum required storage during the operating horizon in reliability. In order to find the best meeting solution to the decision maker, a set of non-dominated solutions which show the tradeoff relationships between the considering objectives were generated. The DM selects the best solution from this explicit tradeoff relationships using his heuristic decision rules or experience. The theory was verified by applying to the Kumi Service Water System. A combined technique of the ${\varepsilon}-constraint$ and the weighting methods was used to generate the nondominated solutions, and the dynamic programming algorithm was applied to find the optimal solution for the discretized multi-objective analysis problems.

This paper presents a method of generation rescheduling using Newton's Approach which searches the solution of the Lagrangian function. The generation fuel cost and $CO_2$ emission cost functions are used as objective function to reallocate power generation while satisfying several equality and inequality constraints. The Pareto optimum in the fuel cost and emission objectives has a number of non-dominated solutions. The economic effects are analyzed under several different conditions, and $CO_2$ emission reductions offered by the use of storage are considered. The proposed approach can explore more efficient and noninferior solutions of a Multiobjective optimization problem. The method proposed is applied to a 4-machine 6-buses system to demonstrate its effectiveness.

Current criticism regarding the "uniformity" of Korean apartments has shown not only tendencies of emotional and unscholarly criticism, but also lack of academic discourse. They tend to stay at the common-sense level and be quite subjective without supporting facts. This research began with questioning the phenomenon of seeing Korean apartments as an object of negative criticism. The research questions for this study are: 1. Of the living space of so-called apartment houses, what elements should be called uniform?; 2. How should the implications of the findings be interpreted? In this context, this study aims to reinterpret criticisms on the uniformity of apartments from a new point of view. First, literature review is done to examine characteristics of Korean apartments in the social-cultural, economic, and physical contexts. Next, existing non-academic, abstract criticisms are classified into three trends, to show that the way of understanding architectural spaces by those criticisms are limited and weighted towards visual perceptions focused only on the shape of architectural structures. Finally, it is argued that the viewpoints of space and residents' experience should be treated as important for the reinterpretation of criticisms on the uniformity. This is validated through presenting relevant cases such as changes of space uses, diversified lifestyles being accepted, and the expansion of living space.

Recently, as a method of green-development and reduction of carbon dioxide emission, increased interest has been focused on a railway. Furthermore, an intensive study has been processed on capabilities of maintenance activities, economic efficiency of maintenance on rail structure and a design of railway structure as well as the development of materials. The purpose of this paper is to develop a deteriorated model of PC Beam Bridge due to timely changes and maintenance activities. Typically, there is definite difference between maintained bridges and non-maintained bridges. As a result of proper maintenance activity, a life time of a structure can be enhanced. In this study, we will research and analyze structures with ongoing maintenance. We will also process same procedures on structures without maintenance. Therefore, we can establish the significant role in a conditional change of a structure. Based on a study, we accomplish the development of a condition-deteriorated model. To develop deteriorated model of PC Beam Bridge, We apply Marcov Theory and develop a transition probability to show the life time of bridge. This study will provide a great benefit to decision making for maintenance activities on the railway bridges for future.

Acupuncture as a therapeutic intervention has been widely used for treatment for many functional disorders, such as substances abuse and mental dysfunction. In general, acupuncture is known to be simple, economic; painless, non-traumatic, and without untoward reaction, being able to inhibit the abstinence syndrome. Although a number of studies on acupuncture have been reported, a few studies described acupuncture effect on drug addiction. Evidences suggest that substances abuses including nicotine, cocaine and alcohol are in part related to its effects on dopamine neurons in the reward pathways of the brain. The effects of acupuncture on drug addiction may be mediated through the neuronal cells within the limbic structures, which are known to be involved in rewarding properties of drug abuse. This essay reviews clinical and experimental evidences for its effectiveness on the drug addiction, and discusses a plausible explanation for the mechanism of acupuncture on substances abuse.

Objective: Low back pain is a primary of source of dysfunction and economic costs. Gluteus medius muscle co-activation and activity pattern change caused the low back pain. Active release technique (ART) is a patented, non-invasive, soft tissue treatment process that both locates and breaks down the scar tissue and adhesions. The purpose of this study was to assess the effects on chronic low back pain using ART on gluteus medius so that suggest usable treatment method for treating chronic low back pain. Design: One group pretest-posttest design. Methods: Twelve patients with chronic low back pain were participated in this study. Subjects in ART group were received 2 times a week for 3 weeks treatments with either ART on gluteus medius muscle trigger points. Outcome measures were conducted by pain intensity with a pain visual analogue scale and pressure pain threshold on gluteus medius. Results: Completion of the intervention, the visual analogue scale was decreased in ART group (p<0.05). Also pressure pain threshold was decreased in ART group (p<0.05). Conclusions: Our results suggest that the response to ART may be usable to treat low back pain. ART was presented to reduce pain level of low back in people with chronic low back pain. Further study is required to management for low back pain due to gluteus medius and more ART study.

Accounting information is essential for users. Useful information helps users to make appropriate investment-related decisions. Segment reporting disclosure plays a practical role for an investor in a business. The article data was surveyed by ordinary least squares to test the effects of corporate governance on the segment reporting disclosure. The article employed time-series data with 136 observations of the top 100 non-financial Vietnamese enterprises listed on the stock exchange in the period of 2018-2019. The research used two popular theories related to stakeholder and agency to explain the effects of factors on segment reporting disclosure. The results have identified two factors that have a positive impact on segment reporting disclosure, namely, the size of the board and the ratio of foreign members to the total number of the board. Accordingly, the managers of the top 100 Vietnamese listed enterprises should increase the number of board members as well as pay attention to the number of foreign members to contribute to improving the information disclosure on the segment reporting. It is the basis to improve the quality of information to ensure completeness and transparency. It contributes to attracting foreign investment to meet the trend of international economic integration.
