Walleye pollock Theragra chalcogramma fisheries in Korean waters have changed dramatically during the last three decades: the highest catches occurred in 1981, followed by continuous decreases through the 1990s, ending with a complete collapse of the population in the 2000s. The major spawning ground of walleye pollock is located in North Korean waters, and some juveniles (called nogari in Korean, <300 mm) migrate to the south for feeding and growth. Since the 1960s, Korean fishermen have often caught juveniles, and the weight (metric tons) of juvenile catch was recorded from 1975-1997. However, because the walleye pollock were not aged, the population age structure was not delineated. We developed a model to estimate the number of walleye pollock of each size class based on catch statistics of adults and juveniles, the catch proportion of each size class, and length and weight information on specimens collected by Danish-seine and drift-gill-net fisheries. The model results demonstrated that the recruitment size of walleye pollock was consistently within the 200-250mm size class, and the highest number of this size class occurred in 1981, although values greatly fluctuated interannually. The number of juvenile pollock was 10.4 times higher than that of adult pollock during 1975-1997. The total yield of juvenile pollock was 0.95 million tons, which was equivalent to about 68.2% of total pollock production. The number of juvenile pollock caught during the same period, however, was 16 billion, comprising about 91.2% of the total number caught. Such high fishing pressure on juvenile pollock is considered one of the main factors causing the collapse of the pollock population.

This study was conducted to investigate the effects of different water temperatures on growth, survival, biochemical composition, and blood physiological parameters of juvenile mandarin fish Siniperca scherzeri. Feed-trained juvenile fish were subjected to four water temperatures (20, 23, 26 and 29℃) with two replicate groups. The fish were fed to apparent satiation twice daily using a formulated diet containing 55% crude protein and 6% crude lipid. After the 8-week feeding trial, survival was >96% in all groups. Weight gain and feed efficiency of fish reared at 26 and 29℃ were higher than those reared at 20℃. The protein efficiency ratio, daily feed intake, and whole body proximate composition were not affected by water temperature. These results indicate that a suitable water temperature range for optimal growth and feed efficiency of juvenile mandarin fish is 26-29℃ under these experimental conditions.

The purpose of this study was to compare the eating habit, food intake frequency and preferred food and taste of juvenile delinquents (100 numbers) and male high school students (100 numbers), using questionnaires from August to October 2004. 1) It was shown that the juvenile delinquents took more unbalanced diet (p<0.05), smoking (p<0.001) and drinking (p<0.001) than general students, while general students had more eating between meals (p<0.01). 2) The intake of food was a significant difference in white rices (p<0.01), bibimbab (p<0.001), kimbab (p<0.001), fried rice (p<0.001), ramen (p<0.001), jajangmyun (p<0.001), jambong (p<0.001), hamburger (p<0.001), pizza (p<0.001) and breads (p<0.05). The juvenile delinquents took more major food than that of general students in all the items except for white rice. It was observed, then, that the juvenile delinquents showed more intake of such subsidiary foods as bulgoki (p<0.001), roasted thin pork chops (p<0.001), grilled pork belly (p<0.001), pork cutlet (p<0.01), sweet and sour pork (p<0.001), chicken with ginseng (p<0.001), fried chicken (p<0.001), kimchi pot stew (p<0.01) and zucchini (p<0.05) than general students, with general students taking more kimchi (p<0.01) and fried or boiled soybean curd (p<0.01). The intake of dessert was a significant difference in yogurt (p<0.01), orange juice (p<0.001), cola (p<0.001), soft drinks (p<0.001), ion drinks (p<0.001), coffee (p<0.001), apple (p<0.01), banana (p<0.001), orange (p<0.001), cake (p<0.001), hot dog (p<0.001), ddokbokgi (p<0.01), mandu (p<0.001), fried fish paste (p<0.05), steamed korean sausage (p<0.001), fried foods (p<0.05), hem & sausage (p<0.001), cheese (p<0.001), ice-cream (p<0.001), candy (p<0.01), chocolate (p<0.001), mayonnaise (p<0.05), jam (p<0.01) and butter & margarine (p<0.01). Then, the juvenile delinquents were shown to entirely have more intake of all the desserts than those of general students. 3) Regarding preference of foods, it was shown that the juvenile delinquents preferred cereals (p<0.05), grilled pork belly (p<0.001), chicken with ginseng (p<0.01), anchovies and small fish (p<0.05), chicken with ginseng (p<0.05), seasoned spinach (p<0.001), seasoned zucchini (p<0.001), milk (p<0.05), coffee (p<0.001) and butter & margarine (p<0.05) while general students did egg (p<0.01), soybean sprout soup (p<0.001), boiled or fried potato (p<0.05), seasoned soybean sprout (p<0.05), boiled or fried soybean curd (p<0.01), fried foods (p<0.01) and snack (p<0.05). For their preference of tastes, hot taste (p<0.01) was higher in the juvenile delinquents. 4) Under general environments there was a change of the difference in their behaviour of pork cutlet (p<0.01) intake in accordance with other family and of milk (p<0.001) and butter & margarine (p<0.05) preference in accordance with growth in a big city between the two groups.

Pediatric rheumatologic diseases are rare systemic diseases that can involve various organs, including the kidneys. Each rheumatologic disease can exhibit characteristic renal involvement, which requires proper treatment and diagnosis. In this review, we discuss renal involvement in classic rheumatologic diseases, including juvenile idiopathic arthritis, Sjogren's syndrome, systemic sclerosis, and juvenile dermatomyositis. Reviews addressing lupus nephritis and antineutrophil cytoplasmic antibody-associated renal disease are complex and tend to cover a wide array of topics, and thus were excluded from this review.

This study aimed to identify the relationship between MBTI personality types and parent-child relationships among the juvenile delinquents non-delinquent adolescents. From the analyses of empirical data, the following tendencies were found. First, delinquent juveniles are more likely to be classified to be such MBTI types as "Extroverted," "Sensing," "Thinking," and "Judging" than non-delinquent juveniles. Second, contrary to popular belief, the juvenile delinquent group was fecund to have more positive attitudes toward their relationship with their parents than the non-delinquent juvenile group. Third, for both the non-delinquent juveniles and the delinquent juveniles, "I" and "P" preferences were related with a positive perception of the relationship with their parents. Fourth, "EJ," as a psychological temperament type, was related with a Positive relationship with parents for both groups. Fifth, the psychological function types were not significantly related with the relationship with parents. Sixth, "EP" and "IP," as psychological attitudes types, were related significantly with a positive relationship with parents. Seventh, the juveniles classified as "ESTJ" had good relationships with parents, whereas "ISTP" types, on the other hand, tended to show the most negative attitudes toward their relationship with parents. The most interesting result of this study was the finding that the "P (perceiving)" types in the non-delinquent juveniles group as well as in the juvenile delinquents group tend to have negative attitudes toward their parents.
