Purpose: This study aimed to obtain basic data on oral health improvement by investigating the EQ-5D index according to the oral prosthesis status of elderly persons aged 65 years or older in Korea using the Seventh Korea National Health and Nutrition Examination Survey. Methods: In this study, 3,426 elderly persons aged 65 years or older were included to analyze the relationship between the dental prostheses status and EQ-5D index in the collected data. Results: Compared to the "complete denture" in oral prosthesis, EQ in case of no dental prostheses or fixed dental prostheses is comparable to removable prosthetics such as "no dental prostheses," "one fixed bridge," and "two or more fixed bridges." Removable partial denture and complete denture required for the maxillary and mandibular EQ-5D index were significantly higher in "not necessary" than in "complete denture necessary" in all the elderly persons. Conclusion: The condition of the dental prosthesis and the need for a removable partial denture and complete denture for the elderly's EQ-5D index were confirmed, and it was found that the fixed dental prostheses were more effective than the removable dental prostheses. Therefore, oral health education programs for the elderly should be developed to promote dental function and oral health maintenance.

Purpose: The purpose of this study was to explore nurses' experience of the role adaptation process and barriers in long-term care (LTC) facilities including nursing homes, daycare centers, and home visit nursing centers. Methods: After in-depth interviews with 13 nurses who were working at the LTC facilities in G province, the data were analyzed using Colaizzi's phenomenological methodology. Results: 17 themes with 6 theme clusters, and 2 categories emerged: nursing role adaptation process in the LTC (role expectation and readiness, role perception and performance, limits of role performance), and barriers to nursing role adaptation in the LTC facility (organizational, situational, and institutional-environmental barriers). Conclusion: The results showed that it is critical to establish the nurses' role in caring for the health of the elderly and maintaining the quality of care in the LTC facilities. In response to the growing demand for quality care in the LTC facilities, more institutional and environmental changes are needed to address the current barriers that prevent nurses from performing their appropriate roles.

This study was conducted to investigate the influence of laminaran from Eisenia bicyclis on serum lipid composition of rats fed high fat and cholesterol diets. Fourty male Sprague-Dawley rats weighing $70{\pm}2.5g$ of 4 weeks old were fed experimental diets for 6 weeks with high fat diet consisting of basal diet plus cholesterol (1%) and lard (10%) for the inducement of hyperlipidemia. The effect of laminaran supplements via drinking waters on serum lipid composition of rat were investigated for 5 weeks by administration of experimental diet group fed basal diet only as normal group, control group fed high fat diet, LL group fed high fat diet plus 0.25% laminaran containing water, and LH group fed high fat diet plus 0.5% laminaran containing water, respectively. As a results of experiments, it was found that LL and LH groups showed significant (p<0.05) decrease in body weight gain and liver weight as compared with control and it may caused by decreased FER. The weight of cecum and adipose tissue (EFP) of LL group showed a significantly (p<0.05) decreased patterns compared with control. It was also found that LL and LH diet groups affects the intestinal length and transit time of rat as significantly (p<0.05) increased in length of intestine and decreased in transit time. In addition, LL and LH diet groups showed a dramatic decrease in triglyceride, total and LDL-cholesterol, and significant increase in HDL-cholesterol compared with control diet group, by which results in decreased in AI. These results indicate that crude laminaran from Eisenia bicyclis has a strong hyperlipidemic and hypercholesterolemic activities in rat fed high fat and cholesterol diet.

This study was performed to investigate the performance state and improvement countermeasure of Primary Health care Posts(PHPs). The operation reports of PHPs(1996 330 PHPs, 1999 313 PHPs) located in Kyongsangbuk-Do and data collected by self-administered questionnaire survey of 280 community health practitioners(CHPs) were analyzed. The major results were as follows: Population per PHP in 1999 decreased in number compared with 1996. But population of the aged increased in number. The performance status of PHP in 1999 increased compared with 1996. A hundred forty one community health practitioners(50.4%) replied that the fiscal standing of PHP was good. Only 1.4% replied that the fiscal standing of PHP was difficult. For the degree of satisfaction in affairs, overall of community health practitioners felt proud. The degree of cooperation between PHP and public health institutions was high and the degree of cooperation of between PHP and private medical institutions was high. The degree of cooperation between PHP and Health Center was significantly different by age of CHP, the service period of CHP, and CHP's service period at present PHP. Over seventy percent of CHPs replied that they had cooperative relationship with operation council, village health workers, community organization. CHPs who drew up the paper on PHP's health activity plan were 96.4 % and only 11.4% of CHPs participated drawing up the report on the second community health plan. CHPs who grasped the blood pressure and smoking status of residents over 70% were 88.2%, 63.9% respectively and the grasp rate of blood pressure fur residents were significantly different according to age and educational level of CHP. CHPs received job education in addition continuous job education arid participated on research program in last 3 years were 27.5%, respectively. CHPs performed the return health program for residents in last 3years were 65.4%. Over 95% of CHPs replied that PHPs might be necessary and 53.9% of CHPs replied that the role of PHPs should be increased. CHPS indicated that major reasons of FHPs lockout were lack of understanding for PHP and administrative convenience, CHPs were officials in special government service governors intention of self-governing body. CHPs suggested number of population in health need such as the aged and patients with chronic disease, opinion of residents, population size, traffic situation and network in order as evaluation criteria for PHP and suggested results of health performance, degree of relationship with residents, results of medical examination anti treatment, ability for administration and affairs in order as evaluation criteria for CHP. CHPs replied that the important countermeasures for PHPs under standard were affairs improvement of PHPs and shifting of location to health weakness area in city. Over 50% of CHPs indicated that the most important thing for improvement of PHPs was affairs adjustment of CLIP. And CHPs suggested that health programs carried out in priority at PHP were management of diabetes mellitus and hypertention. home visiting health care, health care for the aged. The Affairs of BLIP should be adjusted to satisfy community health need and health programs such as management of diabetes mellitus and hypertention, home visiting health care, health care for the aged should be activated in order that PHPs become organization reflecting value system of primary health care.
