Recently, the need for research into environmental and intrapsychic variables to promote active career preparation behavior is increasing, due to the increasing need to cultivate career preparation behavior starting from middle school. On the basis of this need, the purpose of this study is to identify the mediating effects of hope in the relationship between maternal learning involvement and career preparation behavior among middle school students. We surveyed 320 middle school students in W city, Gangwon-do, regarding these variables. We evaluated the results according to Baron and Kenny's (1986) mediating effect test procedure. The findings showed a significant positive correlation between positive maternal learning involvement, such as respecting their children's learning methods and providing academic information and advice, and the students' career preparation behavior and hope. However, the findings didn't show any significant correlation between negative maternal learning involvement, such as pressure for academic performance, and the students' career preparation and hope. Furthermore, hope was found to partially mediate the relationship between maternal positive learning involvement, including academic information and advice, and career preparation behavior, while fully mediating the relationship between career preparation behavior and respecting the students' learning methods. However, it did not have any mediating effect on the relationship between pressure for academic performance and career preparation behavior. These results highlight the important role that instilling hope in students, through respecting their learning methods and advising and providing the necessary academic information, plays in achieving a higher level of career preparation behavior.

The authors had studied the oral environmental changes by salivary salivary pH, amount, periodontal Index in patient with active pulmonary tuberculosis patients. Among the subjects, The experimental group was consisted of 100 patients (50 males and 50 females) of 20-29 years and 100 persons of control group (50 males and 50 females) of 20-29 years. The measurement of salivary amount was performed with wide mouthed plastic (2 Inches) bottle for avoidance of Ionization of SiO2 by using of glass bottle and salivary pH was checked by pH meter 27 radiometer Copenhagen. The results are as follows : 1. The slivary pH does not appear to be characteristic of tuberculous paticents. 2. The obtained salivary amount indicated no significant to the tuberculous patients as compared to the obtained supposedely wealthg individuals. 3. The Russel Index wasfound higher and there had found more periodontal involvement(3 times than normal) in the experimental group.

The Arabidopsis thaliana S-Adenosylmethionine decarboxylase (AdoMetDC) cDNA ($GenBank^{TM}$ U63633) was cloned, then the AdoMetDC protein was expressed and purified. The purified AdoMetDC was inactivated by salicylaldehyde in a pseudo first- order kinetics. The secondorder rate constant for inactivation was 126 $M^{-1}min^{-1}$ with the slope of n=0.73, suggesting that inactivation is the result of the reaction of one lysine residue in the active site of AdoMetDC. Site-specific mutagenesis was performed on the AdoMetDC to introduce mutations in conserved $lysine^{81}$ residues. These were chosen by examination of the conserved sequence and proved to be involved in enzymatic activity by chemical modification. Changing $Lys^{81}$ to alanine showed an altered optimal pH. The substrate also provided protection against inactivation by salicylaldehyde. Considering these results, we suggest that the $lysine^{81}$ residue may be involved in catalytic activity.

Previous studies have suggested that Citrus fruits might suppress the proliferation of various cancer cells. However, little is known about any specific ingredients in the extract of Citrus fruits to exert its anti-proliferative activity in cancer cells. The present study aimed to identify the active ingredients in Citrus fruits to suppress the proliferation of rat hepatocellular carcinoma cells. Among tested compounds, two polymethoxylated flavones (nobiletin and tangeritin) showed significant anti-proliferative activity whereas other compounds (synephrine, rutin, hesperidin) did not. Interestingly, nobiletin as well as tangeritin also decreased the protein amount of gluconeogenic enzymes, PEPCK and G6Pase. The possible involvement of gluconeogenic activity in the proliferation of hepatocellulacarcinoma cells are further to be investigated.

The purpose of this study was to investigate the relationship between the maternal child rearing behaviors and home environmental variables related with children's self-esteem in urban and rural community. Subjects were 435 boys and girls enrolled in grade 4, 5, 6 and their mothers from five public elementary schools in Chonan city and Naju city. The instruments for the study were coopersmith's Self Esteem Inventory Korean Maternal Behavior Inventory and questionnaire on home environmental variables. The data were analyzed by Pearson's one-way ANOVA t-test and Duncan post hoc test. The major findings were as follows: 1. Children's self esteem and 'Affection' and 'Achievement' of maternal child rearing behaviors were a positive correlation. 2. Children's self esteem of urban community was higher than that of rural community. Maternal child rearing behaviors of urban community was 'Achievement' of maternal child rearing behaviors were a positive correlation. 2. Children's self e teem of urban community was higher than that of rural community. Maternal child rearing behaviors of urban community was 'Active Involvement' and that of rural community were 'Authoritaran Control', 'Overprotection' and 'Achievement' 3. There were no differences in children's self esteem with family size. 4. There were significant differences in children's self esteem with parent's educational leveland monthly family income; the higher parent's educational level and the more monthly family income the higher children's self-esteem. 5. There were also significant differences in maternal child rearing behaviors 5. There were also significant differences in maternal child rearing behaviors with 'Achievement' by parent's age monthly family income and family size in 'Reasoning Guidance' and 'Active Involvement' by parent's educational level. in 'Authoritarian Control' and 'Overprotection' by monthly family income and in 'Reasoning Guidance' and 'Authoritarian Control' by family size.

This study empirically examined different patterns of collaborative R&D project with their key success factors(KSFs), using data from 82 projects in the Korean electronic parts industry. The patterns of R&D collaboration were categorized into 4 types by two criteria development motive(technology Push/market pull) and Project initiator (focal firm/partner). The bivariate relationships revealed that project characteristics (technological complexity, market uncertainty), management characteristics (participation in project formulation), problem solving characteristics(problem solving performance of the focal firm, users active role in problem solving, active role of university or research institute in problem solving) and success rates appear to be different among four types of collaboration. Each type of collaborative R&D projects also had different KSFs. The KSFs of type 1 (technology Push and focal firm initiation), for instance, include the strategic importance of the project, focal firms share of cost, active role of university or research institute in problem solving, while those of type 4(market pull and customer initiation) cover reliability of partner relationship, a time at partners involvement, information sharing. The findings suggest that the different contingencies brought different patterns and KSFs of collaborative R&D project, since different information, resources, and partners roles were needed to successfully implement the projects according to development motive and project initiator Finally, managerial, policy, and theoretical implications for the collaborative R&D activities in the Korean electronics parts industry were discussed, based on empirical results of this study.

The purpose of this paper is to investigate characteristics of active information and opinion giver in the interactive-public communication space of internet. More specifically, this study explores that the active information and opinion giver have the same traits with opinion leader, which are personal attributes (topic involvement and individuation), social activity, source of information and influentials, and socio-demographic attributes. The research consisted of a questionnaire, which was administered using e-mail, and 175 replies were returned. The results show that higher activity of sending information and opinion is associated with characteristics of opinion leader. First, It was found that higher activity group in sending information and opinion have higher degree of topic involvement and individuation than lower group. Second, the former is more active behavior than the latter in social activity. Third, it was examined that behaviors of sending and giving information and opinion with interpersonal communication channel was connected with those of the interactive-public communication space in internet. Also, the result of analysis with mass communication channel was found the distinction in three different kinds of magazines which is related with specific media. Finally, characteristics of socio-demography were not different between two group, with the exception of gender.

This study classified consumer personality types of the junior market and examined their clothing behaviors. The subjects were composed of 283 male and 276 female high-school-age consumers. Data were collected through questionnaires. Personality types were classified by the Myers-Briggs Type Indicator (MBTI). Data were analysed with the frequency, $X^2$, factor analysis, Cronbach's $\alpha$, ANOVA and Duncan tests using Windows SPSS 12. There was a significant difference (P<0.001) between fashion involvement and the 8 classified personality types. In fashion involvement, the extroverted feeling type was significantly higher than the other types. In brand image orientation, the extroverted thinking type was significantly higher than the other types (P<0.05). In fashion ad-orientation, the extroverted feeing type was also significantly higher than the other types. In active or passive complaining behaviors, there was no difference. In the selection criterion for clothes of color and design and style, the extroverted feeling type was also significantly higher than the other groups (P<0.05).
