There has been a dramatic increase in public awareness regarding dementia during recent years. However, dementia remains a family affair and patients do not receive adequate care in Korea. This study aims to assist patients and their caregivers by establishing Home and Community based Long-Term Care in a city. The data collected for analysis include five main categories: dementia prevalence, limitations of daily activities of patients, burden of caregivers, the services that patient's family want to utilize, the resources that handle dementia in the community. Major findings can be summarized as follows: 1)The prevalence rate of dementia for elderly people is 13.1 per 100 persons. Alzheimer's disease amount to 38.9% of dementia patients and vascular dementia account for 36.7% of them 2)Eight out of ten patients have mild dementia. Almost all patients have normal ADL. IADL, however, shows different picture. In every items of IADL, about 60% of patients reveals some limitations. 3)The proportion of patients who had medical diagnosis is as low as 20%. Families of patients think dementia as normal aging process and medical doctors in the community do not give special concern to dementia patients. 4)Caregivers does not have proper social support. They suffer from long care time, experience large obstacles in respect of health, daily living, and social activity. 5)Health center and Community welfare center have launched some programs-consultation, home-visiting nursing, day care center, voluntary force mobilization and so on-for dementia patients. But they do not perform expected roles and functions because of lack of skilled personnels and inadequate coordination of relevant organizations for dementia care. 6)Families of dementia patients prefer home helper and home-visiting nurse to hospitalization. For the future, however, demand for institution-based long-term services will increase. We develope community dementia care model based on above findings as follows: 1)Health center execute community cardiovascular control program for the prevention of vascular dementia. 2)Refer to epidemiologic characteristics of patients and preference of family, the most urgent task for dementia care in this city is to expand and organize Home and Community based Long-Term Care. 3)For the continuous and comprehensive care, care plan for a patient must be prepared. Case management team should be builded to prepare this plan and coordinate relevant resources. 4)Special long-term care unit for dementia will be needed in a near future. This unit should have multiple functions, such as day-care center, short stay facility, training center for relevant personnels, besides long-term nursing home considering effective care of dementia and efficient operation of the facility. 5)Voluntary workers deserve their due efforts. Incentive mechanisms must be developed to activate voluntary activities.

The purposes of this research are to examine the effects of muscle relaxation to the rheumatoid arthritis patients' physiological, psychological, and social adaptation, and to verify that the technique Is an effective tool for improving the patients' adaptation. This research utilized a qusi-experimental design that compares the pre-experiment measures and the post-experiment measures. The subjects of this study were 37 out-patients who were diagnosed for rheumatoid arthritis in P university hospital and K clinic between September 12, 1993 and November 30, 1993. The experimental group consisted of patients treated on Monday, Wednesday and Friday. The control group consisted of patients treated on Tuesday, Thursday and Saturday The pre-experimental survey utilized the following tools. The physiological adaptation was measured by a graphic rating scale for pain and activity of daily living. The psychological adaptation was measured by Zung's depression scale and Rosenberg's self-esteem scale : and the social adaptation was measured by Derogatis' psychosocial adjustment scale. The experimental group received muscle relaxation treatment for 15 minutes per day for the period of 2 weeks, the control group received no treatment and had quiet time. The post-experiment measurement was carried out similar to the pre-experiment survey, SPSS $PC^+$ is used to analyze the collected data. The reliabilities of the measurement tools were examined by Cronbach's ${\alpha}$ coefficients. The homogeneities between the experimental and control groups were tested by t-test and chi-square test, hypotheses were tested by t-test. This research found that the general characteristics between the groups were statistically homogenious. The physiological, psychological, and social adaptation between the groups in the pre-experimental survey were also statistically homogenious. The results of this research can be summarized as follows : 1. Concerning the Physiological adaptation, the experimental group showed a statistically lower pain score than the control group. Thus, muscle relaxation was effective to relieve the pain of rheumatoid arthritis patients (t=-2.95, p=.006). 2. Concerning the psychological adaptation, the experimental group showed a statistically lower depression score than the control group. Thus, muscle relaxation was effective to reduce the patient's depression(t=-4.00, p=.001). 3. Concerning social adaptation, the experimental group showed a statistically higher score for the health maintenance and disease control than the control groups. Thus, muscle relaxation was effective for the health maintenance and disease control (t=2.09, p=.004). This research showed that the muscle relaxation is a nursing intervention that can promote the physiological, psychological and social adaptation of the rheumatoid arthritis patients in terms of short-term and cognitive changes. However, more fundomental changes in behavior and long-term physiology could not be found through such a short-term relaxation treatment.

This study was carried out to examine the effects of nutrition education program developed by Jincheon Public Health Center on preschool children's nutrition knowledge and dietary habits and the parents' dietary attitudes. The subjects of this study were five- and six-year-old children as well as their parents. A 5-week nutrition education program was implemented to 104 children in five day care centers, and 107 children in three day care centers were investigated as a control group. Activity tools designed for each lesson such as puzzles, food magnets, story, songs, Pierrot costume, and balls were used. Nutrition knowledge and dietary habits of children and dietary attitudes of parents were evaluated before and after education. Mean nutrition knowledge score in the education group was significantly higher than that in the control group after education (p < 0.001). Mean dietary habit score of three questions (three meals a day, eating at fixed time, eating breakfast) in the education group was also significantly higher than that in the control group after education (p < 0.01). In addition, parents in the education group showed significantly higher mean dietary attitude score than those in the control group even though they did not receive education (p < 0.001). Our nutrition education program was found to be effective in improving nutrition knowledge and dietary habits in preschool children as well as improving dietary attitudes in their parents.

The onset of pronucleus formation and DNA synthesis in porcine oocytes following the injection of porcine or murine sperm was determined in order to obtain insights into species-specific paternal factors that contribute to fertilization. After 44h in vitro maturation, spermatozoa was injected into the cytoplasm of oocytes. After injection, all oocytes were transferred to NCSU23 medium and cultured at 39'E under 5% CO2 in air. Similar frequencies of oocytes with female pronuclei were observed after injection with porcine sperm or with murine sperm. In contrast, male pronuclei formed 8 to 9 h following the injection of porcine sperm, and 6 to 8 h following the injection of murine sperm. After pronucleus formation maternally derived microtubules were assembled and appeared to move both male and female pronuclei to the oocyte center. A few porcine oocytes entered metaphase 22 h after the injection of murine sperm, but normal cell division was not observed. The mean time of onset of S-phase in male pronuclei was 9.7 h following porcine sperm injection and 7.4 h following mouse sperm injection. These results suggested that DNA synthesis was delayed in both pronuclei until the sperm chromatin fully decondensed, and the sperm nuclear decondensing activity and microtubule nucleation abilities of the male centrosome are cell cycle dependent.

Cefixime is an orally absorbed cephalosporin with a broad spectrum of activity against Gram-negative bacteria and is highly resistant to beta-lactamase degradation. The purpose of the present study was to evaluate the bioequivalence of two cefixime capsules, Suprax capsule (Dong-A Pharmaceutical Co., reference drug) and Alpha-Cefixime capsule (Alpha Pharmaceutical Co., test drug), according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty-four normal subjects, $23.5{\pm}3.72$ years in age and $68.3{\pm}8.89$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. There was one week washout period between the doses. After one capsule containing 100 mg of cefixime was orally administered, plasma was taken at predetermined time intervals and the concentrations of cefixime in plasma were determined using HPLC with UV detector. The pharmacokinetic parameters such as $AUC_{t}$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in $AUC_{t}$, $C_{max}$ and $T_{max}$ between two products were -3.91%, -2.23% and -3.18%, respectively, when calculated against the reference drug. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of $log0.8{\leq}{\delta}{\leq}log1.25$ (e.g., $log0.8786{\leq}{\delta}{\leq}log1.0523$ and $log0.8889{\leq}{\delta}{\leq}log1.0512$ for $AUC_{t}$ and $C_{max}$, respectively). The 90% confidence intervals using untransformed data was within ${\pm}20%$(e.g., $-10.37%{\leq}{\delta}{\leq}6.73%$ for $T_{max}$). All parameters met the criteria of KFDA for bioequivalence, indicating that Alpha-Cefixime capsule (Alpha Pharmaceutical Co.) is bioequivalent to Suprax capsule (Dong-A Pharmaceutical Co.).
