Everybody dreams of a bright future. A future career determines the direction and quality of an individual's life. Achieving positive career development is one of the most crucial tasks during adolescence. In both national and personal perspectives, the vocational identity of science-gifted students provides some important points to discuss. The purpose of this study is to examine the vocational identity of science-gifted students. Participants included 103 science-gifted students who have received an acceptance letter from a science-gifted school. The modified VISA (Vocational Identity Status Assessment) model was used to analyze the vocational identities of gifted students with 'a letter to myself in the future'. The study found that vocational identity status of the science-gifted students was determined as Foreclosed and Searching Moratorium. The science-gifted students demonstrated more Commitment than Exploration and Reconsideration. They also showed higher levels in Career Identification, In-Narrow Exploration, and Career Flexibility. In addition, they shared common orientations in vocational identity such as strong enthusiasm, challenging limits, and responsibility towards humanity. We expect that this study will contribute to the social interest of science-gifted students in the area of career education. In order for science-gifted students to nurture their full potential with a deeper awareness of education, follow-up studies have to be conducted to provide greater and ideal career education.

This study was intended to investigate actual conditions and problems relating to a variety of substance which have been used by students. A Questionnaire survey was carried out with the subject of 2411 students in an academic boys' high school, academic girls' high school, technical boys' high school and technical girls' high school in Pusan, from the 15th day to 29th day of March, 1989. The summarized results were as follows. There was not a remarkable difference in distribution of these subjects in boys' & girls' high school. The common and good health condition of subjects accounted for 90 percent or higher. 24.4 percent of them also had smoking experience, 11.6 percent of which continues to smoking. The understanding rate of these substances name other than sedative, psychostimulants and antihypnotic accounted for 90 percent or higher. The experience rate taking these substances for one year showed that anodyne, digestive and nutritive tonic accounted for 70 percent, antihypnotic for 15.6 percent, sedative for 1.4 percent, respectively, and psychostimulants for 0.5 percent. Moreover. it was shown that drugs accounted for 1.5 percent, bond for 1.4 percent, and thinner for 0.5 percent. The rate of the daily experiencers who took anodyne, digestive, nutritive tonic, sedatives, and psychostimulants and so on was 7.7 percent, 6.2 percent, 5.2 percent, 5.9 percent, and 5.0 percent respectively. This fact implied that there was a serious problem in high school students' non - narcotic abuse. The usage rate of these substances for treatment purpose showed that anodyme accounted for 90 percent or higher, and digestive for 70-80 percent, respectively, where girl students showed higher rate than one of boy students. Additionally, there was higher the usage rate for other purposes. The usage rate of drugs was highest when these students felt melancholy and curiousity. Their obtaining place appeared that these students mainly obtained these drugs, bonds and thinners from a small shop or peddler and their friend while they usually obtained other substance from the pharmacy and medical institute. The first usage time of these substances appeared during the middle school (the age of 14-15) which was the highest rate. The smoker of all subjects used remarkly large substances as compared with one of no-smoker. Particularly, it appeared that the usage of drugs was very closely related to smoking. The large number of students did not use these substances for oesrable purposes even though they understood the name of these substances. For this reason, from primasy schools it is required to teach the students dependence and harmful effects caused by these substances abuse. Moreover, it was shown that these students firstly used these substances during the middle school (the age of 14-15)due to curiosity. As a result, it is very urgent to give the students health education suitabale for prevention of these substance abuse, when considering harmful effects of these substances. And so health education for no-smoking. Finally, considering that it is very easy to obtain these substances from a small shop and pharmacy, the regulation of these substances control should be considered and completed in the future.

This study investigated the effects and relationships of various stress, school life adjustment and happiness factors among middle school and high school adolescents. The structural model group effects between boy and girl groups were also investigated. Data was employed from the 'Korean Children and Youth Well-Being Index Survey, 2018' while subjects of the analysis included 5,144 students. Based on the education statistics data, the sample was collected by probability proportional to size. Results utilizing structural equation modeling and multigroup analysis showed that first, school stress, friend stress, and look stress had significant effects on adolescent happiness. School life adjustment had positive significant effects on adolescents' happiness. Parent stress, money stress and school stress had significant effects on school life adjustment. Second, the mediating effect of school life adjustment between stress and happiness was significant with parent, school stress, and financial stress. Third, results of the multi-group analysis by level and gender showed that the structure was similar between boys and girls, with the only differences among mediating effects. Boys had significant mediating effects by school stress, and financial stress, while girls had significant mediating effects by school stress, financial stress, and parent stress. Finally, based on the results of the study, practice and policy implications were suggested to support the promotion of adolescents' happiness.

Streptomyces sampsonii KK1024 having strong chitinolytic activity was isolated from crab-shell rich soil at Muan, Jeolanamdo. The KK1024 produced chitinase, protease, gelatinase and lipase. When 50% of KK1024 culture broth was treated to juveniles and eggs of root-knot nematode, juvenile mortality at 3 days was 81.67% and egg hatch rate at 5 days was 2.00%. When $183.7{\mu}g\;mL^{-1}$ of crude enzyme produced by KK1024 was treated, juvenile mortality at 3 days was 96.00% and egg hatch rate at 5 days was 5.33%. At 1% of butanol extract from KK1024, juvenile mortality was highest with 90.00% and egg hatch rate was lowest with 0%. The comparison of the effect of KK1024 culture broth with only medium, synthetic fertilizer, and commercial nematicide on tomato growth and nematode infection was examined in pot trials. KK1024 culture broth showed lower number of egg mass and gall in plant, and population of juveniles in soil compared with only medium and synthetic fertilizer treatment, but not in commercial nematicide. However, the highest shoot weight and length was discovered in KK1024 culture broth. These results suggest that Streptomyces sampsonii KK1024 producing lytic enzymes and nematicidal compounds can be one of candidates for biocontrol agents against root-knot nematodes.

Computer programming has educational effect on improving high-level thinking abilities. However, students initially have to spend too much effort in learning the basic grammar and the usage model of programming languages, which negatively affects their eagerness in learning. To remedy this problem, we propose to apply the Scratch to a Game Developing Programming Class; Scratch is an easy-to-learn and intuitive Educational Programming Language (EPL) that helps improving the Meta-cognition and Self-efficacy of middle school students. Also we used the Demonstration-Practice instruction model with self-questioning method for activating the Meta-cognition. In summary, a game developing programming class using Scratch was shown to significantly improve the Meta-cognition of middle school students. However it was shown to insignificantly improve the Self-efficacy of girl students group.

We carried out this study for recognizing the staue of child inpatient nursing and providing child inpatient with better qualified nursing. We study this research from March 29, 93 to April 23, 93 to April 23, '93. First admission day in hospital, we ask 50 mothers of hospitalized child inpatient about the value of nursing and self-consciousness of mothers, also ask 10 nurse in charge about the satisfaction of tending child inpatient Two times-third admission day in hospital and leaving day, we inquired mothers the value of nursing of mothers by inquiry papers, each measurement was made up of five indexes. The result of research was as follow: 1. The subjects of research had following peculiarities. Average age : 2.5 years 0~ 1 years : 32.0% Baby girl : 56.0% first baby : 58.0% Experienced inpatient : 52.0% The number of hospitalization times was 1~2 times : 61. 5% The average period of hospitalization : 7 days Infected inpatient with respiratory organ disease : 40.0% The mother's average age of child inpatient : 30.5 years Mother's who finished high school : 90.9% Family that income about 600,000-700,000 won : 32.0% Mothers who belived an religion : 50.0% 2. As hospitalization time goes by, mothers gradually failed to recognize the value of nursing. 3. Self-estimated tending satisfactions have no connection with the value of nursing that mothers recognized. 4. The value of nursing was effected by mothers own personnality-salf-consciousness care, experience of hospitalization, academic background & religoin. So, we find out that the value of nursing had no connection with satisfaction of tending. Nurses must make every effort to provide child inpatient with nursing of good quality, that mothers confirm and nurses satisfy themselves. Also, we have to emphasize the importance of home and school education, because these education have a great influence upon mother s self-consciousness.
