Objective: This study examined the relationships between negative affect, social support, and career maturity among adolescents. Methods: The participants in this study comprised 260 $1^{th}$ junior high school students in a Seoul metropolitan area. They completed questionnaires on level of negative affect, social support, and career maturity. Data were analyzed by means of basic descriptive statistics, Pearson's correlations, and multiple and hierarchical regression analyses. Aiken and West's method was used to determine the interactive model's modality. Results: The major findings were as follows: First, negative affect was negatively correlated with social support and career maturity. Social support was positively correlated with career maturity. Second, significant interaction effects were found between negative affect and social support on career maturity; that is, for male students, significant interaction effects were found between negative affect and social support (parent support) on career maturity (career determinacy/career independence). For female students, significant interaction effects were found between negative affect and social support (peer support) on career maturity (career confidence/career readiness/career determinacy/career independence). Conclusion: These results suggest the need to intervene in relation to social support (parent support/peer support) and to improve career maturity among adolescents.

The purpose of this study was to investigate the relationships of parental attachment and self-differentiation with fear of intimacy perceived by college students. The data of the study were collected through self-administered questionnaire method with 187 male and 159 female college students. The major results of this research were as follows. First, there were significant differences in the level of attachment with parents according to parent's marital statue, living standard, and father's education level. Second, there were significant differences in the level of self-differentiation across sex, age, parent's marital statue, living standard, and parental's education level. Third, the level of attachment with parents was positively correlated with self-differentiation, indicating that the greater the level of attachment with parents, the higher the degree of self-differentiation. Fourth, fear of intimacy was negatively associated with parental attachment and self-differentiation, showing that the greater the degree of fear of intimacy, the lower the lever of attachment with parents and self-differentiation. Finally, multiple regression analysis result reported that emotional cutoff among the four self-differentiation subscales was the most powerful variable predicting the fear of intimacy. The results were shortly discussed in terms of some implications for education and counseling with college students.

Compound K is a major metabolite of ginsenoside Rb1, which has various pharmacological activities in vivo and in vitro. However, previous studies have focused on the pharmacokinetics of a single metabolite or the parent compound and have not described the pharmacokinetics of both compounds in humans. To investigate the pharmacokinetics of ginsenoside Rb1 and compound K, we performed an open-label, single-oral dose pharmacokinetic study using Korean Red Ginseng extract. We enrolled 10 healthy Korean male volunteers in this study. Serial blood samples were collected during 36 h after Korean Red Ginseng extract administration to determine plasma concentrations of ginsenoside Rb1 and compound K. The mean maximum plasma concentration of compound K was $8.35{\pm}3.19$ ng/mL, which was significantly higher than that of ginsenoside Rb1 ($3.94{\pm}1.97$ ng/mL). The half-life of compound K was 7 times shorter than that of ginsenoside Rb1. These results suggest that the pharmacokinetics, especially absorption, of compound K are not influenced by the pharmacokinetics of its parent compound, except the time to reach the maximum plasma concentration The delayed absorption of compound K support the evidence that the intestinal microflora play an important role in the transformation of ginsenoside Rb1 to compound K.

Objective: This study aimed to examine the moderating effect of elementary school students' perception of open communication with their parents in relationship to smartphone dependency and school adjustment. Methods: Participants included 300 fifth and sixth graders attending P and A elementary schools in Gyeonggi Province. Descriptive analysis, correlation analysis, and hierarchical regression analysis were performed to analyze data. The level of significance was set at p < .05 for all analyses. Results: The results of the present study are as follows: First, male students showed higher levels of smartphone dependency than female students, and students' smartphone dependency increased according to age. The students' smartphone dependency was negatively associated with their school adjustment and their perception of open communication with their parents. Second, the students' perception of open communication with their fathers was found to moderate the relationship between smartphone dependency and school adjustment. Conclusion/Implications: These findings indicate that open communication between parents and their elementary school-aged children can buffer the adverse effects of smartphone dependency on school adjustment. This study provides implications for parent education and counseling to improve parent-child communication and subsequently build strong, positive family relationships.

This research is conducted in order to analyze the student's academic performance at the secondary school level in Sindh province of Pakistan. The study was focused on the students who have passed the Matriculation level recently. The sample of size equal to 1097 secondary level students was randomly selected in a way that from each college roughly up to 150 students took part in the survey. The sample selection was further divided on gender (Male=448, Female=649) and Locale (Urban=456, Rural=641). A survey questionnaire was circulated for data collection. The statistical analysis based on Pearson's Chi-Square and Correlation models were carried out using the collected data. The conclusion was drawn from results that strongly revealed that the student's academic achievement at high school level was highly associated to their parent's educational level and socio-economic background. Therefore, it is strongly recommended that the financial condition of the population must be enhanced by taking suitable measures. The affected students should be awarded adequate financial assistance or scholarships to face such hardships of their learning career. Free laptops, learning materials, books, and stationery should also be provided.

Atractylodes japonica and Atractylodes macrocephala belongs to Atractylodes genus and theirs roots are used as 'Baek-chul'(White atractylodes rhizome) in Korea Pharmacopoeia. 'Baek-chul' widely used in traditional herbal remedies in Asia. Concurrently, the 'Baek-chul' demand enormously increased in the market due to the growing interest in favoring health benefits but it is depend on import from China. Thus we conducted breeding research to solve the problems associated with domestically cultivated 'Baek-chul' such as low productivity and low disease tolence. We crossed A. japonica (female parent) and A. macrocephala (male parent) in the greenhouse in September 2000. the next season 119 crossed line seeds were collected and germinated in the green house. Among them we selected the good lines in the same season. then conducted replicated yield trials (RYT) in 2014 to local adaptability test (LAT) in 2015-2016. The results showed that the 'AJM16' line has beneficial charactersitcs like, increased plant height, large rhizome diameter, narrow leaf width compared with a 'Sang-chul' (check cultivar) and varied flower color from A. japonica (female parent). The line 'AJM16' was also exhibited decreased anthracnose symptoms(Colletotrichum gloeosporides Penz.). Simultaneously the root yield of AJM16 was 2,409 kg per are, which was increased 130% higher yield compared to 'Sang-chul' (check cultivar) at three various regions from 2015 to 2016. Therefore, we named AJM16 as new cultivar 'Man-chul'. According the results, we have developed a new Atractylodes spp. hybrid cultivar 'Macn-chul' with high yielding and disease tolerance by National Institute of Horticulture and Herbal Science, RDA, in 2016.

The subject were 1374 adolescents of middle school in Busan(male 698, female 676). The main results were as follows : (1) General trends in the degree of parental monitoring showed that girls had more high than boys, and in the degree of family discord, boys showed more high than girls. In the degree of openness of parent-adolescent communication perceived by adolescents showed that girls had more open communication with mother than boys. Such trends in problem behaviors indicated that adolescents had the attention problem most. According to gender, girls had more problems in withdrawal, somatic complain, anxiety/depression, thought problems, attention problems, destructivity/identity, internalizing problems, total behavior problems in comparison to boys. Boys did delinquent behaviors more than girls. (2) For boys, the monthly income of their family, family discord, and the mother-adolescent communication have a significant direct effect on internalizing problems, externalizing problems and total behavior problems. Besides mother's employment and the type of family have a significant indirect effect on behavior problem. For girls, mother's employment, parental monitoring, family discord, and father-adolescent communication have a significant direct effect on internalizing problems. Mother's employment, family discord, mother-adolescent communication have a significant indirect effect on externalizing problems and total behavior problems. Bisides mother's employment, grade, the type of family, dating have a significant indirect effect on behavior problem. (3) The variables to have a significant influence on the parental monitoring showed as the monthly income of their family, dating, mother's employment, the type of family, the family discord showed as mother's employment on the parent-adolescent communication showed as the type of family. (4) Family discord was the most powerful predicator of problem behaviors of middle school students.
