The purposes of this study were to investigate the transition of elderly's welfare service utilization and to examine the factors affecting their utilization as time passed. To solve these research questions, the behavioral model presented by Andersen and Newman(1973) was applied. Using Hallym Aging Panel data consisted of 3 waves from 2003 to 2007, autoregressive modeling and regression analysis were applied for research purposes. The results of this study were as follows; (1) The experiences of welfare service utilization were increasing gradually. The complimentary service for the aged was utilized generally, but leisure service and community service were not used in common. (2) Past experience of service affected service utilization in the following times. (3) The factors affecting older adult's service utilization were different among the types of services. Nonetheless, the factors affecting continuously during the periods were found: age as predisposing factor and area as enabling factor in the complimentary service; area and existence of spouse as enabling factor in leisure service; education as predisposing factor and service cognition as enabling factor in community service. Enabling factor has affected more consistently than other factors. The results showed that special attention should be paid to balanced regional arrangement for welfare resources and the public relation considering the elderly's intellectual level.

This study is to find out the correlation among the predisposing, enabling, and need factors in Anderson Behavioral Model using the data from Korea Medical Panel Survey conducted in the early part (April 1 - October 31) of 2008. The findings are as follows. It was found that the utilization rate of western medical service was far higher. the influential factor to choose western or oriental medical service taking western medical institutions as the reference group, the influential factor to choose oriental medical institution has significantly increased when the patient who have covered by medical insurance has one accompanied disease and their age was between 45 - 74, compared to the people less than 45 years old. It also increased when the age of the patient was between 45-54 years old, and in the event those who are not covered by medical insurance have accompanied disease and that the disease mobility period is 2-4 years. reviewing the several characteristics of the utilization of western and oriental medical services by the patient with musculoskeletal system disorders, the number of accompanied disease is an influential factor for the utilization of oriental medical services. And, disease mobility period is a significant factor for the utilization of both western and oriental medical services together, though it is not identified in this study. Therefore, it is expected that mutual cooperation between western and oriental medical services is more required for the patient with musculoskeletal system disorders as the aging society rapidly develops. In order to foster oriental medicine, it is required to specialize in competitive disease such as musculoskeletal system disorders.

Objectives: This study investigated the utilization and satisfaction of lunchbox by considering the dietary lifestyle of the consumer, in order to refine the purchasing behavior of adults with experience in using lunchboxes, and to provide basic data for efficient menu configuration and direction towards improvement. Methods: A total of 600 adults in Seoul and Gyeonggi-do answered a self-administered questionnaire designed to investigate general characteristics, utilization, menu preference, satisfaction, prospection, and improvement of lunchbox, according to the dietary lifestyle. Results: The study subjects were classified into 5 groups: 'taste seeking group', 'safety seeking group', 'health seeking group', 'economic seeking group' and 'convenience seeking group. Considering purchase value of the lunchbox, the 'taste seeking group' had a high utilization rate (35.1%) for prices less than 4,000 won (P < 0.05). Lunchboxes were mainly purchased at the lunchbox store (43.3%) and convenience store (37.7%). The important factor that contributed to purchasing a lunchbox was taste (61.3%), which was highest in the 'taste seeking group' (P < 0.01). The 'health seeking group' showed the highest preference for the low-salt diet lunchbox menu (26.0%) (P < 0.05). The satisfaction of 'health seeking groups' was lowest when considering addition of condiments (2.34%), origin of ingredient (2.59%), and provided calorie (2.81%) (P < 0.05). The overall response indicated future use of the lunchbox (69.6%) (P < 0.01); 35.8% respondents recommended the purchase of lunchbox, where convenience of purchase was the highest factor contributing to recommendation (50.2%) (P < 0.05). Conclusions: Taken together, our results indicate that taste was emphasized in every group purchasing the lunch box. Convenience of purchase was the highest factor contributing to satisfaction, which was relatively low when considering addition of condiments, nutrition and origin of ingredients. We propose that it is necessary to improve the development of various menus for increasing satisfaction by selecting the right ingredients contributing to good health of the consumer.
