Recently performing arts pursue a new rootage of the collective intelligence that seeks experimental thinking and diversity in creative convergence. Understanding in this way the concept of artist's horizontal creation structure and individual communication of the public, this study tries to analyze ${\ll}God's\;Eye\;View{\gg}$, an example of convergent performing art. The result of analysis is as follows. The convergence in performing art could be approached through experiential thinking and diachronic of artists by genre, and the interpretation and its value of the result of work be shared horizontally. ${\ll}God's\;Eye\;View{\gg}$ express a dynamic communication and meaning of poetic image, and shows the experimental creation of convergence and the individual communication ability of collective intelligence as a new value of convergence.

This paper describes the purification and partial characteristics of aminopeptidase from Microccus sp. LL3 to utilize the microorganism as a potential agent for industrial application for the purpose of shortening ripening period of cheddar cheese. The optimal temperature and pH for enzyme activity were $35^{\circ}C$ and 7.0, respectively for L-leucine-p-nitroanilide as substrate. The enzyme remained stable for 10 minutes up to $50^{\circ}C$. The activity of aminopeptidase was stimulated by $Mg^{++}$ ion but strongly inhibited by $Hg^{++}$, metal complexing reagents, ethylenediaminetetraacetate (EDTA) and 1,10-phenanthroline. The enzyme was thought to be metallopeptidase. This enzyme had a broad substrate specificity, but was inactive on peptide with arginine as N-terminal amino acid. An intracellular aminopeptidase from Micrococcu sp. LL3 was purified by chromatography on DEAE-Sephacel and filtration on Sepacryl S-300. The enzyme has a molecular weight of 43,500.

The source of prescription of Jihwangeumja to treat the mental confusion due to phlegm caused by kidney 'deficiency and Yin and Yang deficiency is found in 'Hwangjesomunseonmyeongronbang $\ll$黃帝素問宣明論方$\gg$'. The source of prescription of Jihwangeum is found in 'Seongjechongnok $\ll$聖濟總錄$\gg$'. Therefore, it seems reasonable to change the prescription to 'Jihwangeum' from 'Jihwangeumja' and to change the source of prescription to 'Seongjechongnok $\ll$聖濟總錄$\gg$' from 'Hwangjesomunseonmyeongronbang $\ll$黃帝素問宣明論方$\gg$'. In addition, 'Jihwangeum' is influenced by 'Naebosan' in 'Cheongeumbang $\ll$千金方$\gg$'. Jihwangeumja gave the substantial influence on the treatment of 'Endogenous wind due to hyperactivity' of Yeopcheonsa. Jihwangeumja supplements the true Yuan, smooths the circulation of the flow inside a body and coordinates the interaction between heart and kidney so that it ultimately eliminates sputum and activates circulation inside a body. If the guideline of diagnosis is accurate, many kinds of diseases can be effectively treated through the principle of treating different disease with the same therapy. In addition, it will be also effectively used for headache after cerebral hemorrhage, trigeminal neuralgia(sore tongue), diabetes insipidus, nervous breakdown, hyperthyroidism, chronic glomerulonephritis, infertility and anemia.

The objective of this study was to determine the influence of quality grade (QG) on meat tenderness characteristics of ten major muscles from Hanwoo steers. A total of 25 Hanwoo carcasses ($5\;carcasses{\times}5\;QGs$) were selected. Intramuscular fat content, collagen content, sarcomere length, and Warner-Bratzler shear force (WBSF) of Longissimus thoracis (LT), Longissimus lumborum (LL), Psoas major (PM), Semisponals (SS), Triceps brachii (TB), Semimembranosus (SM), Gluteus medius (GM), Rectus Abdominis (RA), Superficialis flexor (SF), and Internal and external intercostal (IC) were determined. IC had the highest fat content, followed by LT, RA, LL, PM, GM, SS, SF, TB, and SM. High-fat muscles such as LT, LL, IC, RA, and PM had significantly (p<0.05) different fat contents among QGs. Collagen contents were significantly (p<0.05) different among QGs. With decreasing QG, increasing collagen content was found in muscles. There were significant (p<0.05) differences in sarcomere length among QGs of several muscles. However, no significant (p>0.05) difference in sarcomere length was found among QGs for LL, PM, or RA muscle. PM had the lowest WBSF, followed by LL, LT, RA, IC, GM, SM, SF, SS, and TB. WBSF of QG $1^{{+}{+}}$ was lower than that of QG 1 for SS, TB, and SM. All muscles of QG 1 showed lower WBSF than QG 3 except TB or IC. Results of this study suggested that differences in WBSF among these 10 muscles by QG were due to differences in collagen content and sarcomere length.

The purpose of this study was to determine the prevalence of obesity and to examine the eating habits of elementary school students in Kwangju. The study was carried out on 931 students(male : 454, female : 477) in September and October of 1996. The results are summarized as follows ; Obesity was defined as body mass index(BMI) that exceeds 20. The rate of obesity was 10.0%(male 4.7$\%$, female 5.3$\%$) in subjects. Subjects were divided into 3 groups : normal group(BMI〈20), mildly obese group(20〈BMI〈25), and moderatly obese group(25〈BMI〈30), respectively. With regard to frequency of skipping breakfast, 9.1$\%$ of normal children and 17.5$\%$ of mildly obese children and 33.3$\%$ of moderately obese children had skipping every morning(p$\ll$0.001). With regard to the regularity of meal time, 62.1$\%$ of normal children had ‘regular meals’but 58.0$\%$ of mild obese children and 50.0$\%$ of moderate obese children had‘irregular meals’(p$\ll$0.05). With regard to meal volume, obese children consumed much more meal volume than normal children(breakfast p$\ll$0.001, lunch p〈0.005, dinner p$\ll$0.001). With regard to try to lose weight, 22.9$\%$ of normal children and 55.6$\%$ of mild obese children and 83.3$\%$ of moderated obese children indicated they had attempted(p$\ll$0.001). The results of this study showed that the prevalence of obesity in elementary school students in Kwangju has a tendency to be increased. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children. (Korean J Community Nutrition 2(4) : 486-495, 1997)

This study was performed to determine the hepatoprotective effects of ethanol extract of loquat leaf (LL) on alcohol-induced liver damage in rats. Sprague-Dawley rats (n=32) were divided into the following four groups: normal group (NOR), ethanol administrated group (ET), ethanol plus LL 200 mg/kg BW/day administrated group (ET-LLL), and ethanol plus LL 400 mg/kg Bw/day administrated group (ET-LLH). Body weight gain and food intake of the ET group were significantly reduced compared to those of the ET-LLL and ET-LLH groups. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) activities elevated by ethanol administration were significantly reduced by LL administration. Serum triglyceride (TG) and total cholesterol (TC) contents and hepatic TG and TC contents of the ET group were significantly elevated compared to those of the NOR group. However, TG and TC contents in the serum and liver were significantly reduced in the ET-LLH group. Hepatic glutathione (GSH) contents of the ET-LLL and ET-LLH groups were significantly elevated, and hepatic thiobarbituric acid reactive substances (TBARS) contents were reduced compared to that of the ET group. Taken together, these results suggest that LL may have a possible protective effect on the improvement of hepatic injury by ethanol administration.

The aim of this study was to investigate the growth performance between two different crossbred strains of Korean native chickens denoted as 1E and 2E with a white semibroiler (LL) from hatch to d-84 post-hatch. A total of 450 one-day-old chicks were randomly distributed into cages which included 15 replicate cages each for 1E and 2E with 9 replicate cages for LL. A three phase feeding program was used as a starter (Day 1 - 35; crude protein [CP] 20.3%; metabolizable energy [ME] 3,059 kcal·kg^-1), grower (Day 36 - 56; CP 18.6%; ME 3,123 kcal·kg^-1) and finisher (Day 57 - 84; CP 16.7%; ME 3,187 kcal·kg^-1). The results revealed that LL had a higher (p < 0.05) BW during d-8 to d-84 compared with the other two cross breed groups. A higher (p < 0.05) ADG was observed from the LL during the entire period except from d-1 to d-14 and d-71 to d-84 when compared with 1E and 2E. Shank length did not vary (p > 0.05) between the strains, despite LL having a SL that was 2.86% higher (p < 0.05) when compared with the other strains from d-15 to d-21 post-hatch, and 1E had a SL that was 2.28% (p < 0.05) higher when compared with the other strains during the first week of the experiment.
