Defining prediction variables related to metamemory for the adults in aging process has worthwhile meaning from the perspective that the produced results can be helpful to reducing the difficulty of memorizing efforts and it can also enhance quality of life of aged. This study attempted to analysis relationship between perceived health status, depression, memory self-efficacy and meta memory for the subjects of middle age and old age adults. This study was designed by adopting descriptive correlational analysis method for the 468 middle and old age adults who are living in Seoul. Samples were selected by convenience sampling. Data collection was done over 1 month period in june 1998. The instruments used in this study were health status measuring scale including depression measuring scale, memory self efficacy measuring scale and metamemory measuring scale which were verified for reliability. Data collected were analized by using SPSS for frequency, Peason correlation, t-test and ANOVA according to the variables character and the study purposes. Results of the study were as follows. 1. Relationship between perceived health status, depression, memory self-efficacy and metamemory. Relational analyses between perceived health status, depression, memory self-efficacy and metamemory supported the hypotheses of 1st, 2nd and 3rd(p < .01). These results suggested that the aged perceived great health status then their memory self-efficacy, and metamemory showed the high scores. In the case of depression when its level became decreased metamemory was inclined to increased. Thus, it is identified that strong relationship exists between these variables. 2. Perceived health status, depression, memory self-efficacy by subject's general characteristics. Scores of perceived health status were high in the group of man compared to the group of women, and also highly educated group showed great perceived health status. Group of persons having occupation showed high score of perceived health status and low depression score. The score of memory self-efficacy and metamemory showed higher in the middle aged than the old aged. The high scores of memory self-efficacy and metamemory were found in the group of highly educated people and who have continuing education. The high scores of memory self-efficacy were found in the group of persons having their job and high metamemory scores found in the group of persons having religion. In summary, the greater perceived health status and memory self-efficacy, the more metamemory scores were likely increased and the more depression level was decreased, the more metamemory was likely increased. Also it was found that general characteristics like educational level, continuing education and religion influenced the metamemory of the aged. Therefore, prevention the aged from getting depression and activation of health promotion are needed to delay time of memory loss.

Inductively coupled plasma is commonly used for electrodeless lamp due to its ease of plasma generation. Optical characteristics significantly depend on the RF power and gas pressure of the plasma. This paper describes the measurement of luminous efficacy as a function of RF power and gas pressure with a goal of finding optimal operating conditions of the electrodeless lamp. The gas pressure was varied from 10 [mTorr] to 100 [mTorr] and the RF power was varied from 10 [W] to 120 [W]. It was found that the luminous flux tends to be decreased when argon pressure is increased, and the luminous flux is increased as RF fewer is increased. It was also found that the luminance efficacy is high when the argon pressure is low and when the RF power is low.

Objectives: The present study proposed to evaluate 1st-month and 3rd-month health status, depression, self-efficacy and medical expenses of a community-based health promotive self-management program for old Koreans. Method: Participants in the CDSMP were selected from elders in a community health center through convenient sampling. The program included a 3-hour session per week for 14 weeks. Outcomes of evaluation in the 1st month and the 3rd month included modified Self-rated Health Status Scale, Center for Epidemiologic Studies Short Depression Scale, Self-Efficacy for Managing Chronic Disease 6-item Scale, and 1-item Medical Expenses Scale. Results: Self-rate health scores increased significantly just after the intervention (16.22), in the 1st month (17.57) and in the 3rd month (19.04) (x2=32.06. p=.000); Depression scores (reversed) also increased significantly just after the intervention (6.04), in the 1st month (7.75) and in the 3rd month (8.39) ( $x^2=29.92$. p=.000); Self-efficacy score increased significantly just after intervention (12.87) but it decreased in the 1st month (12.73) and in the 3rd month (12.04). But all of the three scores were still higher than those before the intervention (8.65) ($x^2=32.42$. p=.000): Medical expense score decreased at the end of the intervention (1.57) but the cost score increased in the 1st month (2.48) and in the 3rd month (2.39) ($x^2$=7.81. p=.050). Conclusion: CDSMP is effective in increasing self-rate health and self-efficacy and in decreasing depression in the Korean elderly. However, no significant effect of the program was observed in decreasing the medical cost of the Korean elderly.

The two objectives of this study were 1) to develop an educational program based on the Self-Efficacy Theory(SET) of Bandura, and 2) to investigate the effects of the educational program on the management of menopause. The investigation process of this study was done in two phases. The first phase was to development an educational program through video tape. A telephone coaching program served as a follow-up to the educational video program and provided encouragement and support to the subjects. The second phase was the experimental stage. This experimentation was conducted to determine whether an educational program based on theory of Bandura would increase self-efficacy and management of menopause. Results : The developed video consisted of 2 parts. Part one discussed symtoms and management of menopause. Part two reflected the vicarious step-by-step success of middle-aged women's of menopause through the effective use of the 5 factors mentioned above. Telephone coaching program served as a followed to the educational video program and provided encouragement and support to the subjects. Total length of video is 32 minutes. Hypothesis stated in phase two were supported by the following result. Experimental group increased general-self-efficacy scores. Experimental group increased concrete-self-efficacy scores. Experimental group increased objective and subjective management of menopause scale.

Purpose: This study examined whether various lower extremity exercises using a Swiss ball in the standing position could improve balance, muscle strength, gait, and fall efficacy in stroke patients. Methods: Twenty-one stroke patients were randomly divided into three groups, each with seven participants. For four weeks, experimental group 1 performed various lower extremity exercises using a Swiss ball, while experimental group 2 executed the same exercises without a Swiss ball, and the control group underwent general physical therapy. The subjects' knee extensor muscle strength, balance, gait, and fall efficacy were evaluated before and after the intervention using portable muscle strength measurement, the Berg Balance Scale (BBS), G-walk, and the Korean Falls Efficacy Scale (K-FES). Results: Knee extensor strength increased significantly in all three groups after the intervention; in particular, a significant increase was seen in experimental groups 1 and 2 compared to the control group. Moreover, all three groups had significantly better BBS scores and higher cadence after the intervention; notably, experimental group 1 had better scores and increased cadence than the control group. Additionally, gait speed was significantly increased in the experimental group 1 than in the control group. The step length of the non-affected leg was also significantly higher in the same group. The K-FES score improved significantly in all three groups, but there was no significant difference between the groups. Conclusion: This study suggests that lower extremity exercises with or without a Swiss ball could be effective interventions to improve muscle strength, balance, gait, and fall efficacy in stroke patients.

This study investigated the effects of Child Care and Teaching(CCT) practice on student teachers'(N=361) perceived Efficacy for Child Care an Teaching(ECCT), including relationships between ECCT and generalized self-efficacy. Instruments were the ECCT scale, the generalized self-efficacy scale, and self-evaluation concerning CCT. Research design consisted of pre-test, CCT practices. and post-test. Results showed that ECCT scores increased after CCT practice: ECCT was related with generalized self-efficacy and to self-evaluation concerning CCT. These findings suggested that CCT experience is important to student teachers' perceived ECCT, and ECCT, in turn, is a predictor of actual CCT behavior.

We studied the effect of self-erase discharge on the luminous efficacy of ac PDPs. We observed through discharge current analysis to confirm that the selferase discharge occurred mainly between sustain cathode and address electrode, which have an influence on the luminous efficacy. The amount and timing of the self-erase discharge was varied to observe its effect on the luminous efficacy. It has been found that the luminous efficacy could be improved by the self-erase discharge when it is adjusted to occur right before the main discharge in the small gap structure. In the long gap structure, on the contrary, the luminous efficacy could be increased when the self-erase discharge is suppressed. Also, various waveforms to control self-erase discharge are suggested and tested in the panel experiments.

The study was to find whether the educational program contributed to increase of knowledge and self-efficacy of the postpartal primiparas. This study aimed at improvement of the educational effect for postpartal primiparas. The Subjects were 34 primiparas who were admitted to the obstetric ward in a University hospital from November 15th to December 9th, 1999. The Subjects were those who had no labor pain at the admission time, had no complications during labor and delivery and, gave birth to a healthy baby. They were tested on knowledge and self-efficacy two times, one at the admission time and prior to discharge. After the first test nurses in a maternity ward taught them on postpartal care. Two tools were developed by authors based on literature review. The test tool fr knowledge of postpartal car consisted of 23 items. The test tool for self-efficacy of postpartal care consisted of 16 items. Analysis of demographic data were analyzed with calculation of percentage. Score differences between the first test and the second test were analyzed with paired t-test. The Spss (Win 8.0) program was used for data analysis. The results are as follows. 1. There were not significant influencing general characteristics of primiparous to pre-educational knowledge. There were significant influencing general characteristics of primiparous to post-educational knowledge : occupation(t=13.04, p=0.00), postpartal education(t=5.51, p=0.02). 2. There were not significant influencing general characteristics of primiparous to pre-educational self-efficacy. There were significant influencing general characteristics of primiparous to post-educational self-efficacy : antenatal education(t=5.53, p=0.02) 3. Primiparas' knowledge of postpartal care increased significantly after education(t=13.04, p=0.00). 4. Primiparas' self-efficacy of postpartal care increased significantly after education(t=5.51, p=0.02). 5. Correlation between knowledge and self-efficacy was r=.360(p=0.03). We suggest follow-up studies to find whether primiparas' self-efficacy will last after discharge or not.
