The effect of the instructional approach that asked students to check their problem-solving processes through a paired think-aloud problem solving after presenting molecular-level pictures and a four stage-problem solving strategy was investigated. Four high school classes (N = 191) were randomly assigned to St group (using Strategy individually), SL group (Solver Listener), St-SL group (using Strategy-Solver Listener), and control group. Although the test scores of the St-SL group on strategy performing ability were significantly higher than those of the control group, there was not significant difference for the scores in the multiple-choice algorithmic problems. Regarding the subcategories of strategy performing ability test, students' ability of understanding given of problems and deriving the proper physical quantity was improved, but their ability of setting up subgoals and reviewing their solving process was very low. The preference to the strategy of the St-SL group was more positive than that of the St group.

Starch gel electrophoresis was used to estimate genetic diversity and population structure of Pyrola fauriena H. Andr. in Korea. The percentage of polymorphic loci within enzymes was $57.1\%$. The values of genetic diversity at the species level and at the population were higher than average values for herbaceous with similar life history traits (Hes : 0.149; Hep = 0.134, respectively), whereas the extent of the population divergence was relatively low $(G_{ST}=0.082)$. $F_{IS}$, a measure of the deviation from random mating within the 12 populations, was 0.298. An indirect estimate of the number of migrants per, generation (Nm = 2.81) indicates that gene flow is moderate among Korean populations of the species. Analysis of fixation indices revealed a substantial heterozygosity deficiency in some populations and at some loci. This indicates that some populations sampled may have been substructured largely due to rhizotamous spread and decrease of population sizes.

This study set up research models and hypothesis in order to analyze those factors assuming that swift trust affects group cohesiveness, group cohesiveness affects organizational civil activities and organizational effectiveness (job satisfaction and organizational commitment) and at the same time plays as a medium for the swift trust, organizational civil activities and organizational effectiveness. Based upon these finding, variables in the ship unit are analyzed through surveys. This shows that the swift trust has statistically a meaningful and beneficial impact on group cohesiveness which has statistically a meaningful and beneficial impact on organizational civil activities and organization effectiveness. In terms of effects of crew members' the swift trust on organizational civil activities, organizational commitment, and job satisfaction, group cohesiveness has a partial medicated effect.. This paper has its significance in practically proving that the established swift trust of crew members increase group cohesiveness, the heightened group cohesiveness results in the changes of behaviors and attitudes of crew members in the seagoing vessel.

Four kinds of kalosaponins from inner bark of Kalopanax pictus Nakai as a medicinal and edible timber tree species growing in Korea was analyzed by HPLC. A considerable range of variation in the contents was observed among population. The kalosaponins contents in inner bark from each population were the highest in the Mt. Barwang (30.37 mg/g on the dry weight basis) followed by Mt. Gariwang, Hanra II, Mangun, Paltan, and Hanra II population. Growth factors that might have influenced the contents of the kalosaponins were also examined. As both analysis results of partial correlation and multiple regression, the weight of inner bark and tree age were influenced the kalosaponin O contents. The kalosaponin B contents was influenced by both the weight of inner layer bark and annual mean DBH increment. The contents of kalosaponins appeared to be closely related to the inner bark characteristics.

The purpose of this study was to find the effects of physical activity program on obese young children's body composition and basic motor skills. The physical activity program was conducted with 16 participants whose Kaup Index were higher than 20 were divided into 2 groups(experimental group and control group) for 12 weeks three times a week. Results of the study are as following. First, the physical activity program was found to improve sub-factors of body composition(weight, body fat mass, % body fat, lean body mass and total body water) in the experimental group compared to the control group. There was statistically significant difference between two groups. Second, the physical activity program was found to improve locomotor and manipulation skills of basic motor skills in the experimental group compared to the control group. There was a statistically significant difference between two groups. Based on these results, the physical activity program have positive effects on the changes in obese young children's body composition and basic motor skills.

This study focused on estimating influential factors of traffic accidents and analyzing traffic accident severity of elderly and non elderly using traffic accident data. In order to reclassify elderly and non elderly traffic accident by a statistical method from entire traffic accident data, multiple discriminant analysis was applied. Also ordered logit model was applied for analyzing traffic accident severities using traffic accident severities as an independent variable and transportation facilities, road conditions and human characteristics as dependent variables. As results of the comparison between elderly and non elderly traffic accident, the traffic accident severity was affected by the age, types of traffic accidents, human characteristics and road conditions as well. Also, transportation facilities and road conditions affected to more elderly traffic accident than non elderly. Therefore, traffic accident severity would be decreased with the improvement of transportation facilities and road conditions for the elderly.

This study investigated the relationship between social support and caregiving self-efficacy among 530 mothers of persons with intellectual disabilities in their childhood(age 3-12), adolescence(age 13-18), and adulthood(age 19-35), exploring the moderating effect of the life span affiliation of the children with disabilities. The analysis revealed that greater perception of social support predicted higher level of caregiving self-efficacy for all the mothers. However, the moderating effect was detected indicating that there were differences in the effects of social support on caregiving self-efficacy across groups. Although social support was found to have some positive effects on caregiving self-efficacy for each group of mothers of both adolescents and adults, no effects for a group of mothers of children. These findings suggested that greater emphasis be placed on the expanded provision of social support for families of persons with intellectual disabilities in their developmental stages following the childhood.

This study utilized one of Hofstede's cultural dimension, collective dimension and validated its influence on individual's change oriented organizational citizenship behavior(COCB hereafter) with mediation of emotional regulation. Previous research on Hofstede's cultural dimensions were mostly conducted at national levels. However, in this study, Yoo's CVSCALE was used to analyze collectivistic tendencies at individual levels and its influence on emotional regulation and COCB were measured. The study distributed 200 paper based self administered surveys to employees of Fortune 500 electronic company in Korea for two weeks period. Findings indicated individual's collectivistic dimension positively influenced COCB and emotional regulation mediated between collectivism and COCB. In conclusion and application, the significance of this research lies in indicating collectivistic culture's positive influence on COCB and emotional regulation as possible antecedents of Change oriented Organizational Citizenship Behavior.
