The future of a country is influenced by the youth. Sound fostering of the youth is important for the country's future. Because of mechanization, industrialization and urbanization of our society, many social problems, such as confusion of the sense of value, dehumanization, money worshi n.0, ppings, juvenile delinquency are increasing. For the solution of problems of juvenile crime and dehumanization, bibliotherapy should be practiced in juvenile reformatories, schools and societies. The purpose of this study is to investigate the effectiveness and value of reading. And also the characteristics, brief history, principles and procedures of bibliotherapy are examined. In addition, the book catalog suitable for bibliotherapy is considered. The results of the study are as follows. (1) In order to solve the problem of dehumanization, and the confusion of the sense of value among young adults, we should enrich and cultivate the characters of young adults through the bibliotherapy. So, bibliotherapy for the treatment of human nature of juveniles should be practiced in the juvenile reformatories, schools and societies. (2) The values of reading in the past were inspiration, information and recreation. But, in recent times, the interest in therapeutic value of reading is increasing. (3) Bibliotherapy is a kind of psychotherapy using selected reading materials. A n.0, pplication scopes of bibliotherapy are very wides, including mental medicine, alcoholic poisoning, drug addiction, juvenile delinquency, counselling and education for school life, etc. (4) The principles of bibliotherapy consist of identification, catharsis, insight and it has self therapeutic principles through the reading. The procedures of bibliotherapy is similar to any other kind of psychotherapy: the participant's statement, diagnosis, treatment, continuous recognition of remedial value. (5) The well suited reading materials for bibliotherapy are literature and biography. Literature and biography are familiar to everyone, because they describe the mentalities, emotions and life styles of human beings. (6) The standard reading lists for bibliotherapy for the proper guidance of juvenile delinquency should be prepared for the solution of developmental tasks, such as, drinking, smoking, friendship, family, love, money, marriage, pregnancy, violence, etc. Finally, Bibliotherapy should be introduced to our school settings and corrections institutions for the proper guidance and prevention of the malpractice of the youths. In addition, we should be endeavor to develop the standard reading lists for bibliotherapy and case study.

Nowdays the prison is the only correctional for juvenile delinquents not to be the second offenders in Korea. Originally the correctional education aims to let criminals go back to the society as a decent citizen after correcting them and prevent them from comminitting crimes repeatedly. Being considered to increase the second offenders in juvenile delinquency, the purpose of this study is to investigate the actual condition and problems of juvenile correctional education in Korea and to find out the solution of problems. First of all, this study examines the actual condition of the juvenile delinquency in Korea. The number of juvenile crimes has been increased from 1985 to 1995. In 1997, the current education in correctinal institutions for juvenile delinquents is inferior to that of developed countries. On the basis of this investigation, improvement plans which will be fit for the circumstances in Korea are suggested. The conclusion of this study are summarized as follows 1. Correctional institutions will be improved to accommodate the proper number of convicts. 2. Correctional officers should be qualified proffessinals who can achieve the aim of correctional education successfully. 3. In order to cultivate he social adaptability of convicts, the expansion of open prison is needed. 4. It is neccessary to classify convicts by means of moderized and scientific methods. 5. Correctinal education consist of various practical courses on jobs, After complenting these vocatinal training, the convict can obtain certificates. 6. The government has to has to plan policies that the released convicts can get jobs for living. 7. Owing to keeping prisons sanitary, it is very helpful for convicts to have thebelief that they are not abandoned by the member of their society. 8. Convicts are given opportunities to participate religious activities by their free-will. If above improvement plans are sufficiently accomplished, correctinal education will obtain good results, It is also effective to minimize the repetition of offence by ex-convicts.

The diet composition of juvenile Trachurus japonicus were studied using 195 specimens collected from 2013 (May, June, July, and September) to 2014 (May, June, and July) in the coastal waters of Geumodo, Yeosu, Korea. The size of juvenile T. japonicus ranged from 4.3 to 15.2 cm in body length (BL). Juvenile T. japonicus was carnivorous and crustaceans predators that consumes mainly consumed copepods. Its diet also included small quantities of decapods, cirripedians, nematods, chaetognathans, fishes, amphipods, cumaceans, ostracods and euphausiids. The graphical method for feeding strategy revealed that juvenile T. japonicus is an opportunistic and specialized predator on copepods, especially Corycaeus. affinis, and showed narrow niche width. Juvenile T. japonicus showed ontogenetic diet change. Small size group individuals (4.3-8.0 cm BL) mainly consumed copepods. The portion of this prey item decreased in the large size group (8.0-15.2 cm BL), and this decrease was paralleled with increased consumption of decapods.

Hydro-acoustic surveys with scientific echo sounder were carried out to estimate the total density and distribution of the juvenile cod in Jinhae bay, Korea. The surveys were conducted 4 times from May to June using 2 frequency method (38kHz and 120kHz) and beam trawl were used to investigate the species composition. Also the catch amounts of juvenile cod were compared with the cod density estimated by the hydro-acoustic method. It was confirmed that the juvenile cod was stayed in Jinhae bay in early June and There was the relationship between catch of juvenile cod and the estimated density by hydro-acoustic survey. The number of juvenile cod was consequently about 365,000 fish (CV 12.9%) in May and 113,000 fish (CV 9.2%) in May based on the hydro-acoustic data.

The postembryonic development of the Korean crayfish, Cambaroides similis (Koelbel, 1892), was described in detail and compared with those of other known species of Astacidae and American Cambaridae, and phylogenetic relationship of the genus Cambaroides was discussed. Ovigerous females of the Korean crayfishes appear in May. Durations of juvenile stages 1 and 2 are two and four weeks at 15.0 $\pm$ 0.5$^{\circ}C$, respectively. From juvenile stage 3, it leaves from its mother. It is considered that C. similis is very closely related more to the Astacidae than to the Cambaridae in the characteristics of the maxillule of juvenile stage 1 and the antenna, maxilla, pleopod, and telson of juvenile stage 2.

The relationship between dietary practices and juvenile delinquency was studied using a dietary survey. Subjects were selected from juvenile delinquents who were under the supervision of the Seoul Probation Office of the Ministry of Justice. The study group consisted of 52 male and 52 female delinquents. As a control group, 104 exemplary high school students were selected in Seoul. A questionnaire was designed to find out the subjects' general characteristics, dietary habits, lifestyle, eating behavior, food frequency, and nutrient intake using the 24-hour recall method. Compared to the exemplary students, the juvenile delinquents were significantly different in education level, family status, monthly allowance, residence status, breast fed, parents' education level, parents' concern. In dietary habits, fifty-eight percent of the juvenile delinquents ate 2 or fewer meals per day, preferred to eat with friends, and liked hot tasting foods. The juvenile delinquents consumed more ion drinks (OR = 9.26 CI: 3.83 -22.37), rameon (OR = 7.67 CI: 3.21 - 18.33), cola (OR = 6.75 CI: 2.91 - 15.69), soft drinks (OR = 6.12 CI: 2.53- 14.81), steamed korean sausage (OR = 5.34 CI:2.31 - 12.32), hamburger (OR = 5.15 CI: 1.91 - 13.87), kimbab (OR = 3.63 CI: 1.76-7.46), ddokbokgi (OR = 3.17 CI: 1.58-6.38), candy (OR = 3.08 CI: 1.41-6.73), white rice (OR = 2.59 CI: 1.19-5.64), hotdog (OR = 2.52 CI: 1.31-4.86), and less rice mixed with grains (OR = 0.02 CI: 0.01-0.05), tangerine (OR = 0.06 CI: 0.02 - 0.20), milk (OR = 0.29 CI: 0.14 - 0.60), roasted fish (OR = 0.32 CI: 0.28-0.99, anchovy (OR = 0.35 CI: 0.17 - 0.72), seaweed (OR = 0.37 CI: 0.16 - 0.83), and tofu (OR = 0.48 CI: 0.23-0.99) than the exemplary students. With respect to the juvenile delinquents, the nutrient intakes lower than 75％ of the Korean RDA were for riboflavin (75.0％) and calcium (47.9％) among the boys, and calcium (46.9％) and iron (60.4％) among the girls. To prevent juvenile delinquency, nutritional education and well-balanced school food service meals should be emphasized so as to improve the management of dietary practices.

Purpose: The purpose of this study was to compare the differences in clinical signs and symptoms, and psychological profiles of temporomandibular joint osteoarthritis (TMJ OA) between juvenile and adult patients. Methods: Two-hundred eighty-three TMJ OA patients who visited the Orofacial Pain Clinic of Seoul National University Dental Hospital were classified by juvenile (153 patients; mean age $14.2{\pm}1.7$ years, range 9-16 years) and adult (130 patients; mean age $34.0{\pm}2.8$ years, range 30-40 years) groups, and compared the clinical symptoms based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) axis I guidelines including Graded Chronic Pain (GCP) scale, mandibular range of motion, and the associated symptoms. Psychological profiles were also evaluated using the Symptom Checklist 90-Revision (SCL-90-R). Results: Juvenile patients reported lower pain intensity and a lower prevalence of headache and clenching than adult patients. Their mandibular range of motion was also higher than adult patients. Juvenile patients showed a lower percentage of patients with T-score above 50 in somatization (SOM), obsessive-compulsive (O-C), interpersonal sensitivity (I-S), and paranoid ideation (PAR) than adults. Based on the GCP scale, the percentage of the high disability group was lower in juveniles. Conclusions: Juvenile TMJ OA patients generally showed milder clinical symptoms than adults. Adult patients showed higher prevalence of psychological problems and higher disability than juvenile patients. Age should be considered in evaluation and treatment of TMJ OA patients to achieve better treatment results and understanding its pathophysiology.

Most grid sorting has been used to sort out flatfish in shrimp fisheries, while double grid systems have been tested to separate smaller shrimp. The escape of juvenile red seabream through separating panels made with steel grids or large mesh tested for masking effects in a two-species system. Fish behavior was observed in a circulating water tank. The escape rate was 20% greater with the separating codends than with the normal codend in the single-species experiments. The rates in the two-species experiments were 30% or 20% greater than the single-species rates for the normal or separating codends, respectively. The seabream retention rates in the grid separator codend decreased as rockfish retention increased, possibly due to a threat effect. Conversely, the retention rate of both species increased concurrently in the net separator, possibly due to a masking effect. The escape rates of juvenile red seabream varied by compartment in the mesh separating codend. These results suggest that grid separating codends can be used in the field as towed fishing gear to reduce juvenile catch.

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.
