To increase the mating rate of Bombus ignitus used as insect pollinator, we investigated the sexual maturity time of B. ignitus. In investigating ovary development such as the number of eggs per ovariole and spermatheca size, the time of sexual maturity of queen was 10 days after eclosion. In case of male, the number of sperm was 246 thousand at immediately after eclosion, and was highest as 480 thousand at 9 days, and tended to show a dramatic decline at 35 days (87 thousand). The more mating time, the less the number of sperm. In consideration of number of sperms, the time of sexual maturity of male was 3-15 days after eclosion. In the sexual maturity time of queen in mating, the queen was not mated at immediately after eclosion, and showed a decrease in 20 days. In terms of the rate of mating and oviposition, the favorable time for mating of queen was 9-20 days. On the other hand, the male showed 3.3% of mating at immediately after ecolosion, showed the highest of 43.3% at 6 days after eclosion, and tended to decrease in 25 days. The sexual maturity time for mating of male was 6-20 days. In summary, our results indicate that sexual maturity time of B. ignitus in reproductive organs and mating is most favorable in 9-12 days after eclosion for queen and 6-9 days for male.

Purpose: This study was conducted to identify the sexual maturation, parenting attitude, maturity fear and emotional and behavioral problems of girls in elementary school, and to examine the relation between these variables and factors that influence emotional and behavioral problems. Methods: Participants were 128 second, third and fourth year students from 3 elementary schools. Data were analyzed using t-test, ANOVA and $Scheff{\acute{e}}$ test, Pearson correlation coefficients, and stepwise multiple regression with SPSS/WIN 21.0. Results: Emotional and behavioral problems were related to eating rate, eating breakfast, frequency of late-night snacks and main communicator on pubertal development. Emotional and behavioral problems showed a positive correlation with maturity fear and father's parenting attitude (strictness) and a negative correlation with parenting attitude and father's parenting attitude (intimacy). Maturity fear, father's parenting attitude, eating breakfast, and main communicator on pubertal development had significant influence on emotional and behavioral problems of girls in elementary school. Conclusion: Findings show that for effective management of emotional and behavioral problems in elementary school girls, programs including coping with maturity fear, supportive parenting of father, diet education, and functional communication with mother on pubertal development should be developed.

Indonesian varieties were compared with Korean varieties on three different sowing times, each of which had three different nursery periods, at Suwon, Korea (126$^{\circ}$ 19'E and 37$^{\circ}$ 16'S). Indica-type varieties with exception of late-maturing ones had heading regardless of sowing time and nursery period. As the Korean varieties com-pared with those, the earlier sowing plots with shorter period of nursery gave better result in yields and yield components.

This study is conducted to analyze the difference among college students' department satisfaction, career maturity, and career stress, and to examine the influence of department satisfaction and career maturity on career stress. A survey was done among 824 college students using the scales on department satisfaction, career maturity, and career stress and the following results were found. First of all, department satisfaction, career maturity, and career stress had statistically significant differences based on students year, age, academic records, entrance motive, peer relation, and health condition. Secondly, the subfactors of department satisfaction, namely, course satisfaction, relationship satisfaction, general satisfaction, and recognition satisfaction, showed statistically significant differences according to age, gender, academic records, entrance motive, peer relation, and health condition. Thirdly, the subfactors of career maturity, namely, determinacy, participation, independence, tendency, and compromise, had statistically significant differences according to year and age. Lastly, career maturity and department satisfaction considerably influenced career stress: when department satisfaction and career maturity were lower, career stress was higher. These results indicate that department satisfaction and career maturity correlate with career stress. Therefore, in order to decrease career stress, college students who maintain a low level of department satisfaction and career maturity should receive active guidance and education.
