The purpose of this study was to examine the correlation between Juvenile alcohol use and their criminal patterns. The data were collected through questionnaire surveys. Subjects serving for this study were 971 delinquent adolescents in Korea, sampled from 6 juvenile corrective institutions and 2 classification judging institutions, using a census method. Their age range was between 12 and 21. Data were analysed by IBM PC using SAS program. Statistical methods employed were Chi-square and frequency analysis. 1. Of 877 respondents, the number of adolescents committed criminal behaviors while the intoxicated were 230(26.2%), and 647(73.8%) were in a non-intoxicated state. 2. Adolescent under intoxication showed a higher rate of aggressive crimes and assault crimes, whereas adolescents under the non-influence of liquor tended to commit property climes and violations of criminal special law Drunken state adolescents during committing criminal behaviors used knifes, stones or fist-kicking as criminal tools, whereas drug use or without weapons in non drunken state. Most crimes have happened without any tools in both group. 3. In comparison of the alcohol user and the non-user, most alcohol-related crimes among adolescents were committed at AM 0:00 to AM 4:00 during the weekend in the dark, cloudy, and stormy-rainy day, while non-alcohol related crimes were at afternoon of weekday in the clear day. The places that the criminal activities occurred were streets, amusement places such as disco-theque, fields and their own house among alcohol users, whereas victim's house, another person's house and restaurant were chosen among non-alcohol users. 4. The victims assaulted by Juvenile offenders in both drunken and non-drunken state were mostly passer-by(65.4%), followed by their friends(25.1%). And the conditions of victims showed a significant differences between the drunken adolescents and the non-drunken adolescents. The victim's conditions assaulted by intoxicated delinquent adolescents were in quarreling or drunken state, whereas non-alcohol related crimes were directed against victims in a sleeping or irresistible state. 5. Almost over the half of delinquent adolescents perceived their delinquency as wrong behaviors. and alcohol non-user tended to more significantly perceive their criminal acts as wrong conducts. About the half of respondents answered that they committed their criminal acts in spite of having a very good Judgement while doing crimes, the author did not found a significant difference between the two groups. The reasons given for crimes were manifested as follows: it can be seen that ‘to get money for amusements’(30.4 % of all motives) were most common, followed by ‘to commit accidentally the offences’(23.8%), ‘curiosity or heroism’(18.9%). alcohol related crimes tended to be accidental and impulsively without any clear planning, while non-alcohol related crimes tended to be purposeful, directed to make money motivated by curiosity or a desire to live heroically. In Conclusions. the correlation between alcohol use and Juvenile criminal behaviors has been examined in this study. Generally, alcohol use had been found to be highly correlated with aggressive assault crimes including robbery, burglary and rape etc.

This study is to verify between Juvenile delinquents and normal juvenile groups using MBTI personality types. This study aims to know personality types on the juvenile delinquents and apply to creative school education administration. The research was performed as below: First, Measuring and descriptive statistical analysis were performed. One hundred and two subjects who were youths disposed of Seoul nambu youth alternative education center. Data were collected from July to October in 2012. Second, Questionaries assessing demographic and MBTI(Myers-Briggs Type Indicator) by Carl Jung were administered. Third, statistical analysis was done by SPSS for Window 12.0. To Verify the reliability of the measures and correlations between questionnaire items, and to find out the difference of the specific personality types, were used frequency analysis and Pearson Chi-Square. The results of this is significant personality types of juvenile delinquents are 'E', 'P', and 'SP'.
In order to standardize the juvenile abalone rearing technique, we selected sample farms by region in East, West and South coasts of Korea and Jeju island. We also have reviewed previous literature and visited farms to survey on the management of abalone juvenile production, spawning, hatching and so forth. Results of investigation are as follows: The light colors of tanks for larvae breeding are good for a frequent examination of larvae behaviour changes during the breeding period. The tank for the abalone juvenile production is a rectangular form in general and its size should amount to 3.5 m in length and 1.2 m width. It also should be built with proper drainage. The best age and size of adult for juvenile production are 3-6 years old individuals, with 9-12 cm separate burial and 125-150 g average weight. To induce spawning, the use of the exposure on air and ultraviolet ray together was the most effective. The density of larvae by plate should be 150-300 individuals and the proper stocking density was est imated and amount to 10-30 individuals. It has been shown that a correlation between water surface size($X_1$) and number of plates ($Y_1$), when producing abalone juveniles, is quite high and it is described by equation $Y_1=138.88X_1-5,736.8\;(R^2=0.9028)$. In addition, it has also been shown that a correlation between production of abalone juveniles ($Y_2$) and number of plates ($X_2$) is high and it is described by equation $Y_2=4.554X_2+12,493\;(R^2=0.8818)$. In Jindo region where a mass production of juveniles abalone has been done, it was shown, that a correlation between rearing water surface size ($X_3$) and production of juveniles abalone ($Y_3$) is very high and this relationship was described by the equation $Y_3=747.03X_2+94,359(R^2=0.9809)$. It has also been shown that a correlation between water surface size ($X_4$) and production of abalone juveniles ($Y_4$) in nationwide is high and the relationship between this variables was described by equation $Y_4=635.85X_4+99,923\;(R^2=0.9020)$.
The purpose of this study is to explore the relative influences of juvenile delinquency using variables from Hirschi's social bonding theory, Agnew's general strain theory, Gottfredson and Hirschi's self-control theory, and Akers' social learning theory. The data derived from a sample of 2,018 high school students taken from National Youth Policy Institute in 2013. Multiple OLS regression analysis indicated that social learning theory has the greatest impact on dependent variables than other theories. The results of regression analyses also explore the notion that without the social bond, general strain, and self-control variables, there is very little loss of explained variance when these variables are removed from the full equation. However, when the social learning factors are eliminated from the full equation, the change in $R^2$ is dramatic. This result supported the idea that social learning variables had the strongest effect on the juvenile delinquency of Korean adolescents. The most important implication of this study is that it is the first study to test four major theoretical models for juvenile delinquency in Korea. It also makes a number of important contributions toward the further utilization of social learning in investigating juvenile delinquency for Korean high school students.
To study the distribution of larva and juvenile of the sand eel, Ammodytes personatus in the Kangwon coastal, samples were collected by the larva net (RN 80 net) and small drag net at 60 stations from January 1996 to December. Appearance season of larva and juvenile of sand eel was appeared untill the January to June in the Kangwon-do coast, and the densities of them were high in June. Appearance phase, length frequency distribution of larva and juvenile of sand eel were distributed that the average standard length 10.0~30.0mm in the temperature range of $5.0{\sim}6.0^{\circ}C$ at the January to March, and April to June occurred the average standard length 40.0~80.0 mm in the temperature range of $7.2{\sim}12.0^{\circ}C$. It was distributed in southern part of Kangwon-do coast until the February to March 1996. And association of the sand eel migrated to the northern and middle part of Kangwon-do coast at April when surface water temperature was higher than $7.2^{\circ}C$. It was considered that the migration of the abundance larva and juvenile of sand eel in this area is mainly affected by the water temperature.
In quantitative studies of clinical signs, rock bream of adults and juveniles infected with Megalocytivirus IVS-1 isolated from rock bream (Oplegnathus fasciatus) in Korea showed average $4.49{\pm}1.13$ and $4.85{\pm}1.06$ of spleen index respectively. In challenge experiments, Megalocytivirus IVS-1 induced 100% cumulative mortality in both adult and juvenile rock bream. However we found 60% cumulative mortality in juvenile red sea bream (Pagrus major) even after 30 days of injection, which contradicted with the results of other laboratories. Interestingly, IVS-1 infected red sea bream of the same juvenile size with rock bream showed lower spleen index compared to that of rock bream. In real-time PCR, there was continuous increasing of the numbers of viral copies ($2.03{\times}10^7$ copies/mg) in the spleen of juvenile rock bream infected, which were different from those in adult rock bream showing plateau level after reaching to the peak level. Moreover, enlarged cell numbers in the infected spleen were also increased continuously in the juvenile but not in adult of rock bream, even decreased after reaching to peak level. Consequently, significant differences in clinical signs: cumulative mortality. spleen index and viral copy number were found between rock bream and red sea bream, but not between adult and juvenile rock bream. Certainly quantitative expression of clinical sign as in this study may be a way to compare the progression of megalocitiviral disease more accurately in different species or physiological conditions.
This Study investigated the differences of risk assessment tool and personality assessment inventory (PAI) by recidivism types of juvenile delinquents, the psychological factors that have a influence of juvenile behaviors. 268 incipient Juvenile criminals who had committed crime in the areas of Seoul, were categorized in the three degree of recidivism types. The result showed the significant differences among risk assessment tool, such as family functioning risk factor, school risk factor, away-from-home risk factor, delinquent risk factor, and personal risk factor. PAI scores among the recidivism type showed the significant differences on SOM, DEP, PAR, SCZ, BOR, ANT, ALC, DRG, AGG, SUI, STR, NON, DOM, and WRM. The predictor variables explained a risk assessment tool were STR, ALC, DEP, DOM and WRM in PAI scales. And the interventions and preventions about juvenile delinquents discussed in psychological aspects.
This study aims to examine the effects of art therapy on challenging behavior of schoolchildren. For this purpose, I selected one class of 4th year student of S primary school, located at Jeongeup city, Jeonlabukdo, and selected 4 study subjects through examination of K-CBCL children. juvenile behavior evaluation scale, characters, school life and K - HTP test. With regard to procedure of this study, I carried out art therapy program at the art class for 60 minutes one time a week for 4 months, a total of 17 sessions from Apr. 3, 2007 to July 24, 2007. I made this program with some modification in reference to Arts Therapy Technique (Counpia Remote Training Center, 2005), Group Art Therapy (Choi Seon Nam. Kim Gap Sook. Jeon Jong Kuk, 2007) and the Effects of Peer Group Art Activity on Sociality Skill of Offensive Children (Park Ju Yeon. Lee Byeon In, 2005). For each child, I compared and analyzed the changes in score of K-CBCL children. juvenile behavior evaluation scale, behavior by K-HTP (dynamic house-wood-human figure test) analysis and by school life(KSD) image analysis before and after treatment. I also carried out qualitative analysis on behavioral feature of each child for each session. This study obtained the following conclusions. First, child A showed positive change in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, K-HTP image test and school life. Since he was so active and wanted to obtain good evaluation from anyone that he frequently had quarrel with friends, spoke against others well and beaten others much but was changed and did not speak against others or beat. Second, child B showed clear difference in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, but no significant difference in K-HTP image test and school life. However, I observed substantial changes. While he could not speak frankly to others, felt empty in mind and was offensive in personal relations, he was changed, did not have quarrel with others or speak against others that much and improved his relationship with friends or teachers. Third, child C showed positive change in score of K-CBCL children juvenile behavior evaluation after art therapy program. In comparison of K-HTP image test and school life treatment before and after treatment, he still longed for mothers in mind but found rather stable after treatment. Fourth, child D showed positive chance in score of K-CBCL children. juvenile behavior evaluation scale after art therapy program, but almost no changes in K-HTP image test. But he depicted good relationship and socializing with other friends in school life. While he could not carry his point due to social immaturity and felt depressed, he got more confident. This result of study showed that art therapy had positive effects on correction of schoolchildren.

To suggest ecological management plans for invasion of Salix gracilistyla, stepwise environmental sieve of seed dispersal, germination, seedling and juvenile stages were investigated. About 84% of total seeds were released between May 6 and 10. Germination rates significantly declined with decrease of light intensity from 100% to 30% and 0% (p<.001), but above 60% of seeds germinated in all treatments. Difference of germination rates with 0 and 2cm water level was not significant (p = .571). With increase of elapsed time after seed dispersal, germination rates significantly decreased (p<.001), and seed viability was lost within 16 days. Considering both germination rate of seed and survival rate of seedling, survival rate of all dispersed seeds was only 5% when 8 days passed after seed dispersal. All 22-day-old seedlings (height: 1cm) died under flooding of twice level as its height. With decrease of light intensity from 100% to 30%, survival rates of seedling decreased from 90% to 33% (p<.001). In the case of 45-day-old juvenile (height: 20cm), survival rate was 70% under the water level same as its height. There was significant interactive effect of water level and light intensity on the growth of juvenile (height: p<.001, dry weight: p<.01), and survival rate of juvenile was 10% under +20cm-water level and 30%-light intensity condition. The following management plans for invasion of S. gracilistyla are recommended from these results. (1) Dry condition should be maintained at fringe of wetlands for about two weeks at seed dispersal and germination stage (early May~mid May). (2) Water level should be raised to about 5cm at fringe of wetlands for about two weeks at seedling stage (mid May~early June). (3) Water level should be raised to over 20cm at fringe of wetlands for a long time at juvenile stage. Planting trees for shading can raise management effectiveness (mid June~). (4) As water level manipulating is performed as fast as possible for controlling seedling and juvenile, management become easier and more effective.
This study was carried out to produce the grafts of Juglans sinensis by juvenile grafting method which epicotyl of newly germinated seeds were used as stocks and juvenile fresh shoots were used as scion. The results obtained were as follows ; 1. When plastic tube installed covering up seed with soil up to 6cm height for diameter increment of epicotyl, the epicotyl can be grown up to thickness of 10mm. 2. When the soft fruit branches and the soft water sprout with the terminal bud 8cm to 12cm long were used as scions, the survival rates showed 90 Percent. 3. The optimum date for making juvenile grafts was around the 20th of May, and the survival rates of grafted seedlings showed 86 percent in average. 4. The grafted seedlings showed first sprouting the 15th of June, that is 25 days after making graft, and the sprouting rate was 72 percent. 5. The height-growth of grafted seedlings finished at the end of July, and diameter growth lasted into the end of October. 6. There was positive correlation between the height of grafted seedlings and the diameter at root collar. 7. In general, it takes two years to make plantable graft seedlings from hardwood scion and stock, but the juvenile graft seedlings can be easily obtained in a year and so it seems to be economic.
