We tested the effects of various distillers dried grains (DDGs) in a formulated diet on growth and body composition of juvenile sea cucumber Apostichopus japonicus. DDG is a solid residue obtained by filtering an aqueous mixture of fermented rice with Aspergillus oryzae and yeasts. Six isonitrogenous and isocaloric diets (DDG0, DDG-G, DDG-C, DDG-K, DDG-W, and DDG-P) were formulated to contain 20% DDG obtained from different Makgeolli factories. Juvenile sea cucumber (average weight, $2.1{\pm}0.02$ g) were randomly distributed in eighteen 50-L rectangular plastic tanks (40 L of water each) in a seawater flow-through system at a density of 50 juveniles/tank. Three replicate groups of sea cucumber were fed each of the six experimental diets at a feeding rate of 5% body weight per day for 22 weeks. At the end of the feeding experiment, survival and weight gain of the juvenile sea cucumber were not affected by the type of dietary DDG (P > 0.05), and the proximate and amino acid compositions of the whole body were not affected by dietary DDG diets (P > 0.05). These results indicate that rice-based DDG is a potential dietary ingredient that could be used at dietary concentrations of up to 20% for growth of juvenile sea cucumber.

Juvenile dermatomyositis is a common inflammatory muscle disease of childhood, characterized by weakness in proximal muscles and specific skin rash. In case of juvenile dermatomyositis without characteristic clinical features, non-invasive imaging tools such as $^{99m}Tc$-HDP three-phase bone scan are very helpful in diagnostic workup of myopathies. We report a case of 13-year old female with juvenile dermatomyositis, in which $^{99m}Tc$-HDP three-phase bone scan was useful in diagnosis and assessing therapy response.

The content of anserine, taurine, and L-histidine was measured by HPNC in the muscle of mature(670~690g) and juvenile(80~120g) rainbow trout fatmed in Chungsun, Korea. The concentration of anserine and taurine was higher in mature rainbow trout than in juvenile, but that of L-histidine was lower in mature than in juvenile. When measured with the chemiluminescence(CL) assay, anserine and taurine showed very powerful antioxidative activity above physiological concentration rainbow trout. Taurine still showed antioxidative activity below physiological concentration, while anserine showed prooxidative activity below that. L-Histidine was prooxidative dose-dependently. In TBA method, while taurine showed very week antioxidative effect, anserine appeared very powerful antioxidant and L-histidine prooxidant at physiological concentration. There was no synergism between anserine and taurine and anserine inhibited prooxidative effect of L-histidine.

The main objective of this study was to provide anesthetic criteria of clove oil for an effective manipulation and transportation of red spotted grouper, Epinephelus akaara. When anesthesia temperature (20, 24, and $28^{\circ}C$) and concentration of clove oil (25, 50, and 75 ppm) were increased, the anesthesia and recovery time decreased and tended to be similar to each other between juvenile and adult. Also, as the temperature and concentration increased, the ratio of exposure time and recovery time between juvenile and adult were decreased. When plasma cortisol concentrations were compared for 48 h after anesthesia with 50 ppm of clove oil, both the juvenile and adult fish grew up to 12 h; however, thereafter decreased and there was no significant difference from control at 48 h.

This study is aimed to examine the effects of juvenile delinquents' self-esteem on their sociality. To this end, the study conducted a survey of 549 secondary and tertiary students (534 males and 15 females) in delinquent reformatories in four major cities such as Seoul, Busan, Daegu and Daejeon. The result showed that the self-esteem of juvenile delinquents has a significant positive effect on with leadership, autonomy and reliability. Moreover, their self-esteem at home also has a significant positive effect on autonomy. Based on these findings, the study presents implications and suggestions for future studies.

Settlement of larvae, growth, and survival of juvenile abalone (Haliotis discus hannai) were examined after feding of 5 species of benthic diatoms (Cocconeis suctellum, Navicula sp Nitzschia longissima Bacillavia paxillifera, Licmophora flabellata). All of the benthic diatoms were isolated from natural populations on plastic plates for the abalone. The settlement of larvae, shell growth, and survival rate of juvenile abalone varied by diatoms species. The highest settlement rate of larvae was $43.1\%$ with the Cocconeis suctellum diet. Daliy growth rate reached a maximum at 64.1 ${\mu}m/day$ with the Navicula sp. diet and a minimum at 22.4 ${\mu}m/day$ with the Licmophora flabellata diet. Survival rate of the juvenile abalone was highest at $62.0\%$ with the Navicula sp., Cocconeis suctellum , and Nitzschia longissima diets. Survival rate of the Juvenile abalone was significantly higher than the control group with mixed diatom population diets (P<0.05). Therefore, diatom . species composition in diets can be a controling factor for the settlement, growth, and survival rates of Juvenile abalone.

To develop a trap to prevent the catch of juvenile rockfish Sebastes inermis and bycatch, we compared the fishing characteristics of four traps with different mesh sizes (35 mm and 50 mm) and flapper connecting lines (FCL) (3 lines and 4 lines).The number of rockfish caught in trap 1 (35 mm, 4 FCL) was 200, and juvenile rockfish (15 cm or less) accounted for 49.0%. The number of rockfish caught in trap 2 (35 mm, 3 FCL) was 185, and juvenile rockfish accounted for 58.9%. The number of rockfish caught in trap 3 (50 mm, 4 FCL) was 82, and juvenile rockfish accounted for 4.9%. The number of rockfish caught in trap 4 (50 mm, 3 FCL) was 68, and juvenile rockfish accounted for 22.1%. The total catch (bycatch rate) in trap 1, trap 2, trap 3 and trap 4 was 565 (64.6%), 637(71.0%), 260 (68.5%) and 276 (75.4%), respectively. The catch per unit effort (CPUE) for juvenile rockfish in trap 1, trap 2, trap 3 and trap 4 was 0.8, 0.9, 0.0, and 0.1 individuals/trap, respectively. The CPUE of bycatch in trap 1, trap 2, trap 3 and trap 4 was 2.9, 3.6, 1.4 and 1.7 individuals/trap, respectively.

This study aim to identify preference of main and side dishes of 681 children who lived in Seoul and Gyoung-gi (Incheon) in 2007. To accomplish this, we divided the children into three age groups, an infancy group (below 6 years of age), a middle years group (between 7 and 12 years of age) and a juvenile group (above 12 years of age). Specifically, 145 children were in the infancy group (boys 68, girls 77), 300 children were in middle years group (boys 138, girls 162) and 236 children were in juveniles group (boys 131, girls 105). The average body mass index (BMI) of the parents of the respondents appeared to be normal, and the majority of the parents had bachelor degrees. Across all age groups, most fathers were office workers and most mothers were housewives. The preference for staple foods showed that the infancy group and the middle years group preferred rice the most, while the juvenile group preferred stir-fried rice the most out of 5 grain items. Evaluation of the preference for different types of noodles showed that both boys and girls from the infancy group preferred jajangmyun, while those in the middle years group and the juvenile group preferred spaghetti. For breads, both boys and girls from the infancy group had the highest preference for cake, while boys and girls in the middle years group and boys in the juvenile group preferred pizza the most, and girls from juvenile group preferred cake the most. Evaluation of the preference for soups and pot stew revealed that both boys and girls in the infancy group preferred seaweed soup, while boys from middle years group preferred seol-long-tang and girls from middle years group preferred seaweed soup. Boys and girls from the juvenile group preferred seol-long-tang the most. For hard-boiled foods and stir-fried foods, members of all age groups preferred beef boiled in soy sauce the most and hard-boiled peppers the least. Finally, comparison of the preference for roasted foods, seasoned vegetables and kimchi revealed that the infancy group preferred roasted seaweed the most and that both the middle years and juvenile group had the greatest preference for roasted galbi.
