Horticultural traits and genetic relationship were evaluated for 83 melon (Cucumis melo L.) cultivars. Survey of a total of 36 characteristics for seedling, leaf, stem, flower, fruit, and seed and subsequent multiple analysis of variance (MANOVA) were conducted. Principal component analysis (PCA) showed that 8 principle components including fruit weight, fruit length, fruit diameter, cotyledon length, seed diameter, and seed length accounted for 76.3% of the total variance. Cluster analysis of the 83 melon cultivars using average linkage method resulted in 5 clusters at coefficient of 0.7. Cluster I consisted of cultivars with high values for fruit-related traits, Cluster II for soluble solid content, and Cluster V for high ripening rate. Genotyping of the 83 cultivars was conducted using 15 expressed-sequence tagged-simple sequence repeat (EST-SSR) from the Cucurbit Genomics Initiative (ICuGI) database. Analysis of genetic relatedness by UPGMA resulted in 6 clusters. Mantel test indicated that correlation between morphological and genetic distance was very low (r = -0.11).

The study was aimed to find out whether there are differences in perception toward multicultural youth's career problems according to the four stages of life cycle(adolescence, pre-marriage, family formation child rearing), and multicultural families and non-multicultural respondents. Also is was aimed to find out if there is an interactive effect on problem recognition. A nationwide survey was conducted using questionnaire on the perception of multicultural youth careers and a total of 1,338 responses were used for the final analysis. For the research purpose, a two-way MANOVA was performed. First it was found that multicultural family members had higher negative perceptions of multicultural appearances than non-multicultural family members had and the adolescents had relatively low negative perceptions of personal relationships and social life adaptation of multicultural youth. Also, as a result of examining whether there is an interaction effect on perception of career problems of multicultural adolescents between multicultural families and their life cycle stages, interaction effects existed in all aspects of family environment, career activities, education, and institutions. It has been shown that there are differences in the perception of career issues among members of multicultural families or among non-cultural families.

The purpose of this study was to examine the effect of donation expenditure details and the shift in awareness as a result of disclosure of donation expenditure details in order to promote constant donation by nonprofit organizations in the course of marketing activities. The first experiment was configured through $2{\times}2$ intergroup element design based on 2(feedback on donation expenditure details: available vs. unavailable) ${\times}$ 2(donation awareness: expenditure vs. exchange), and furthermore, MANOVA was performed. The results showed that the satisfaction with donation was higher when the donation expenditure details were disclosed(M=5.125, SD=0.437) and that the relation maintenance intention was higher(p<0.01) when the donation expenditure details were disclosed M=5.328, SD=0.459). In addition, the main effect was validated by using the bootstrapping method. The results of overall model validation showed that satisfaction & trust(=0.843, p<0.01) and satisfaction(=0.267, p<0.01) and trust(=0.691, p<0.01) had a positive(+) relationship. Based on aforesaid results, donors are expected to have greater trust if nonprofit organizations make effort to ensure transparent and detailed disclosure of information on expenditure of donations made by donors. Succeeding studies would need to investigate the effect that might vary depending on the type of feedback methods, etc.

The purpose of the study was to investigate the effects of On-Line Community Assisted Team Learning (OCATL) activities on academic achievement and team member's Shared Mental Model(SMM) subscale scores. Two studies were conducted over two semesters in different universities. The first study was aimed at examining the effects of OCATL on university students' academic achievement using pre- and post- experimental design. For this experiment, 133 university students composed of 80 male and 53 female students from 13 colleges participated. The OCATL activities included the orientation of OCATL, seminar on collaborative learning, on-line community assisted team learning with sixteen hour participation during one semester and a final report (or a term paper). To measure these students' academic achievement, their pre- and post-semester's GPA were compared. The results of paired t-test revealed a significant difference in academic achievement (p<.05). The second study was designed to compare the scores of SMM subscales of the experimental group with the OCATL activities and those of the control group without using OCATL activities. The data was collected using the scale of Shared Mental Model(SMM)-short version developed by Johnson in 2011[18]. For this study, 74 participants from 10 teams served as an experimental group and 15 teams which were not exposed to OCATL activities served as a control group. The MANOVA results showed that SMM subscores of two groups measured after the experiment were statistically significantly different: The experimental group with the OCATL activities showed high scores on general task and team knowledge, general task and communication skills, attitudes toward team and task, team dynamics and interactions, team resources and working environment, and satisfaction with the team.

The key objective of this study was to analyze sampling efficiency of various fish sampling gears for a lentic ecosystem health assessment. This survey was conducted at twelve sampling locations of Jinyang Reservoir in November, 2008 and June, 2009. Sampling gears used in the field were fyke net (FN), gill net (GN), trammel net (TN), casting net (CN), minnow trap (MT), and kick net (KN). Fishes sampled in Jinyang Reservoir were 29 species, in which tolerant species, as a proportions of the total numbers, dominated the fish community compared to the sensitive species. Overall sampling indicated that 28 species (3,567 individuals) were sampled by the CN and 15 species (3,108 individuals) were sampled by the FN along with 14 species (577 individuals) by the TN, 7 species (107 individuals) by the GN, 6 species (59 individuals) by MT, and 5 species (95 individuals) by KN, respectively. Statistical analysis (MANOVA), based on CPUE of the fishing gears showed that fish species and numbers of the CN were significantly (p < 0.05) greater than those of any other sampling gears. In contrast, sampling gear of MT and KN showed the least efficiency in our survey. This survey is a preliminary results for the tests of sampling gear's efficiency in lentic ecosystems, thus further extensive studies are required for the verification.

The purpose of this study was to compare the 5 OEs of Korean gifted elementary students and non-gifted and to find out the gender difference in gifted and non-gifted to clarify the best predictor of giftedness in gender group. The total subjects of this study were 372 Korean third, fourth, and fifth grade elementary school children. One hundred sixty six children of them belonged to a gifted group, and 206 were non-gifted group. Two hundreds one out of 372 subjects were boys and 171 were girls. The Overexcitability Questionnaire II(OEQII) used in this study was developed by Falk, Lind, Miller, Piechowski, & Silverman in 1999. The OEQ II is consisted of 50 Likert-type items, classified into five subscale: psychomotor, sensual, imaginational, intellectual, and emotional. And it was translated into Korean. It was administered in group sessions during the winter of 2008. Data were analyzed with SPSSWin 12.0. MANOVA was conducted to determine statistical differences by giftedness and by gender. The results revealed that the level of 5 OEs of gifted elementary children was higher than non-gifted(normal) children. The intellectual OE showed the most powerful explanation among the 5 forms of OEs. This study also found the gender difference within the gifted group as well as with the whole subjects. The mean scores of sensual, imaginational and emotional OEs were higher in girls than in boys. Based on the gender difference within the gifted group and the whole group, it is assumed that imaginational OE may be the best predictor of gifted girls among school-age children.

The main purposes of this study were to assess Asian travelers' perceptions of service quality provided by Korean restaurants and to identify the relationships among perceived quality, satisfaction, and behavioral intentions. The survey was administered during one-month period of January-February 2009, targeting tourists from China, Taiwan, and Japan who were visiting Korea through escorted tour packages offered by several Korean travel agencies. A total of 223 copies of the questionnaire were collected for the data analyses such as descriptive statistics, factor analysis, MANOVA, and multiple regression analysis using SPSS 12.0 program. The main results of this study were as follows: 1) The results of the gap analysis indicated that the service quality in several areas provided by the Korean restaurants did not meet the tourists' expectations; 2) The factor analysis identified four underlying dimensions of travelers' perceptions of overall service quality provided by Korean restaurants ("value and quality of foodservice", "menu choices", "service quality of employees", and "quality of surrounding area"); and 3) Through multiple regression analyses, three determinants ("value and quality of foodservice", "menu choices", and "service quality of employees") were found to have the greatest impact on tourists' satisfaction and behavioral intentions.
