Objective: The purpose of this study is to explore and analyze the way pre-service early childhood teachers think about teacher happiness through metaphor analysis. Methods: A total of 225 pre-service teachers were selected from 4-year universities in the Gyeongnam area and open questionnaires were distributed to the participants. A total of 207 out of the 225 questionnaires were selected for the study. Results: First, based on psychological well-being, positive interpersonal relationship, self-acceptance, autonomy, environmental control, and life purpose were derived. Pre-service early childhood teachers typified teacher happiness into five types: positive interpersonal relationships, self-acceptance, autonomy, environmental control, and life purpose. Second, pre-service early childhood teachers perceived teacher happiness as positive. Third, pre-service early childhood teachers perceived interpersonal relationships, self-acceptance, and purpose of life as positive, while environmental control and autonomy were perceived as negative. Conclusion/Implications: The results of this study suggest that it is necessary to improve the quality of teachers' education and to develop a program to raise positive awareness of future early childhood teachers. These study results can also be used as basic data for high quality teacher education.

The paper aims to evaluate the quality of fisheries census statistic and to provide some desirable directions and improvements for the future fisheries census, conducted by the Government. For the quality diagnosis of fisheries census statistic, specific processes of fisheries census and statistical qualities of each dimension are surveyed and evaluated by a Government's practician, two external examiners and a research group. Results show that census design, data analysis and quality control are evaluated relatively low in specific processes, and accessibility and comparability are evaluated relatively lower than relevance, accuracy, timeliness and consistency in statistical qualities. For minimizing the sampling errors, the probability proportion method should be employed in sampling methods from currently simple sampling method. In addition, fisheries census statistic is desirable to include and compare with those of different countries for consumer oriented data system.

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Training Program to decrease anxiety and depression and to increase the quality of life for kidney transplant recipients. The subjects were selected randomly among the patients who underwent renal transplant at three major transplantation hospitals in Seoul, Korea. The observed subjects in this study consisted of 56 patients who had renal transplantations between one to twelve months prior to this study. The patients did not take any regular physical exercise. This study was carried out between November, 1999 and March, 2000. The study groups were divided into 3 groups; exercise training group (n=16), self efficacy group (n=18) and control group (n=22). The exercise training group received self efficacy promotion and exercise training program for 12 weeks. The self efficacy group received self efficacy promotion education, but no exercise training was given. The control group was not offered any education. The anxiety, depression and quality of life were evaluated 3 times, before the experiment, after 8 weeks and after 12 weeks. The data were analyzed with mean, standard deviation, Chi-square test, ANOVA and $Scheff\acute{e}$ test. The results were as follows: 1. After the experiment, anxiety and depression scores of the exercise training group and self efficacy group were more significantly decreased than those of the control group (p=.05). 2. After the experiment, the quality of life score of the exercise training group and self efficacy group were more significantly increased than those of the control group (p=.05). This study showed that the Self Efficacy and Exercise Training Programs were effective. Therefore, it is expected that the Self Efficacy Promotion and Exercise Training Program could be widely applied as an effective independent nursing intervention to decrease anxiety and depression and to increase quality of life for kidney transplant recipients.

The study was conducted to evaluate the effect of chromium nanoparticle (CrNano) on growth, carcass characteristics, pork quality, and tissue chromium in finishing pigs. A total of 100 Duroc$\times$Landrace$\times$Yorkshire barrows (average initial BW of 64.78$\pm$0.83 kg) were divided into 10 pens, 10 pigs per pen. 5 pens of pigs were fed with control diet (corn-soybean meal, 1.05% Lys) and others were fed with control diet addition with 200 $\mu$g/kg Chrome (Cr) from CrNano. During the trial, all pigs were given free access to feed and water. After 35 days trial, 10 pigs from each each treatment (weight similar to average group weight, 91.34$\pm$1.31 kg for control group, and 92.26$\times$0.56 kg for CrNano treated group) were sacrificed to measure carcass characteristics, pork quality, and to collect the samples of longissimus muscle, liver, kidney and heart. The results indicated that the addition of 200 $\mu$g/kg CrNano decreased feed: gain ratio by 3.56% (p<0.05) compared to the control group. Pigs fed CrNano had 14.06% higher (p<0.05) carcass lean percentage, 19.96% (p<0.05) larger longissimus muscle area and 25.53% lower (p<0.05) carcass fat percentage, 18.22% lower (p<0.05) backfat thickness. Drip loss in chops from pigs fed CrNano was decreased by 21.48% (p<0.05) and weights of longissimus muscle and semimembranosus were increased by 16.33% (p<0.05) and 14.87% (p<0.05) respectively. In addition, supplemental CrNano resulted in 184.11% (p<0.05), 144.99% (p<0.05), 88.13% (p<0.05) and 52.60% (p<0.05) increment of Cr concentration in longissimus muscle, liver, kidney and heart, respectively. These results suggest that supplemental CrNano has beneficial effects on carcass characteristics, pork quality and individual skeletal muscle weight, increase tissue chromium concentration in selected muscle and organs.

Purpose The purpose of this study is to investigate the factors that affect the user satisfaction and continuous use intention of the improved ATCIS in the Korean Army. Design/methodology/approach Based on the various theories in relation to IT continuance, user satisfaction was identified as the main factor with regard to the continuous use intention of the improved ATCIS. In addition, computer self-efficacy, education-training, and system quality were hypothesized as antecedent variables to user satisfaction, and information security stress was set as a moderating variable for these relationships. Findings Survey results show that computer self-efficacy, education and training, and system quality had a positive effect on user satisfaction, and information security stress was found to moderate these relationships. The effects of computer self-efficacy and education-training on user satisfaction were higher in the group with low information security stress. However, the relationship between system quality and user satisfaction was higher in the group with high information security stress. User satisfaction is found to have a positive effect on the continuous use intention even with habit considered as a control variable.

The objective of this study was to investigate the effects of different amounts of pumpkin powder on the quality characteristics of hobakpyeon using physicochemical and sensory properties, as well as on its retrogradation rate during storage. As the amount of pumpkin powder increased, the following effects on the quality characteristics were observed: moisture and amylose contents decreased while protein content increased (p<0.05), and in vitro protein digestibility (IVPD) decreased (p<0.05). Levels of slowly digestible starch and resistant starch fractions increased, while the content of rapidly digestible starch decreased. The starch digestion index and rapidly available glucose content also decreased. Among the physical properties, the L-value decreased while the b-value increased (p<0.05). Texture profile analysis revealed that all textural properties except adhesiveness decreased, and presented significant differences in hardness and chewiness (p<0.05). Sensory properties such as color, flavor, and sweetness increased while others such as wetness and chewiness decreased (p<0.05). Effects on the physicochemical properties during refrigerated storage were also compared between the control and 9% hobakpyeon (9%HP). According to the results, moisture content gradually decreased in the 9%HP compared to the control. Amylose content significantly increased in 9%HP whereas no significant changes were observed in the control. In both types of hobakpyeon, IVSD decreased significantly, showing higher values in 9%HP, whereas mechanical hardness increased, showing lower values in 9%HP. The L-value decreased significantly in the 9%HP whereas no significant changes were observed in the control. In conclusion, the above results suggest that hobakpyeon with low IVSD may be obtained by the addition of 9% pumpkin powder, and also showed that pumpkin powder delayed the rate of retrogradation in 9%HP during storage.
