The purpose of this study was to explore a causal model of mother's parenting and children's locus of control to self-control in elementary school children. The subjects were 582 children of 4th, 5th and 6th grade. The instruments were Self-Control Rating Scale for Children, Locus of Control Scale for Children and Parenting Scale. The major findings of this study were as follows. 1) Children's locus of control, mother's warmth-acceptance and permissiveness-nonintervention , mother's education level and children's sex predicted children's self-control. 23% of the variance of children's self-control was explainer by these variables. 2) Mother's warmth-acceptance had a direct and an indirect positive effect through children's locus of control on children's self-control and was the first contribution factor. Children's locus of control had a first direct effect on children's self-control. 3) Mother's permissiveness-nonintervention had a direct and an indirect negative effect through children's locus of control on children's self-control. Mother's education level had a direct and an indirect effect through children's locus of control on children's self-control. Children's sex had a direct and an indirect effect through mother's rejection-restriction on children's self-control. Mother's rejection-restriction had an indirect effect through children's locus of control on children's self-control. Family income had an indirect effect through mother's parenting on children's self-control. Father's education level had an indirect effect through mother's permissiveness-nonintervention on children's self-control.

The purpose of this study was to explore the effects of mothers' self-efficacy, parenting behaviors, and children's achievement motivation on children's self-efficacy. Subjects were 591 fifth- and sixth-graders and their mothers in Busan. Statistics and methods used for data analysis were Cronbach's alpha, Pearson's correlation, Multiple Regression, and Path Analysis. Several major findings of this study were as follows: 1) Any difference was not found by sex in children's general and total self-efficacy. Girls' social efficacy, however, was higher than boys'. 2) Achievement motivation had a direct positive effect and was the first positive contribution factor to the self-efficacy of both sexes. 3) On boys' self-efficacy, mothers' own had an indirect positive effect through achievement motivation, and their parental role efficacy had a positive effect, direct or indirect, through their affective parenting behaviors and the boys' achievement motivation; also mothers' affective parenting behaviors had an indirect positive effect through achievement motivation, and their controlling parenting had a direct negative effect. 4) On girls' self-efficacy, mothers' own had a direct positive effect, and their parental role efficacy had an indirect positive effect through their affective and controlling parenting behaviors and the girls' achievement motivation; also mothers' affective parenting behaviors had a positive effect, direct or indirect, through achievement motivation, and the controlling parenting had a negative effect, direct or indirect.

This study develops principles for determining and managing costs applicable to grants and cooperative agreements for basic research. We investigated financial management policies of funding agencies and foundations in the United States, United Kingdom, Canada, Germany, Japan and Korea. Also we surveyed opinions of researchers and research fund administrators in Korean universities. Based on our review of funding agencies and our survey, the recommended management policies for grants and cooperative agreements are as follows: (1) Cost Structure. Cost of a sponsored agreement is comprised of the allowable direct costs and allocable portion of the allowable indirect costs. Direct costs can be further divided into salaries and wages, equipment, and other direct costs. (2) Salaries and Wages. Salaries and wages applied to a grant are paid for services rendered to the project during the period of performance of the particular agreement. In order to give researchers financial incentive, researcher allowance can be paid up to 30% of his/her regular salary. (3) Equipment. Any property purchased with grants which has an acquisition cost of 5,000,000 won or more per item and a normal life expectancy of two years or more is defined as equipment. Expenditures for special purpose equipment are allowable provided the acquisition of items is necessary for the research supported by the grant. (4) Other Direct Costs. Other direct costs are comprised of travel (both domestic and foreign), materials, other costs. Other costs may not exceed 30% of total other direct costs. (5) Indirect Costs. Since there is no clear consensus on indirect costs and additional budget is necessary to support actual indirect costs, the practical policy at the moment is to give a research support expense in lieu of indirect costs. In the future, however, some form of actual indirect costs should be supported. This study develops principles for determining and managing costs applicable to grants and cooperative agreements funded by the Ministry of Science and Technology. This research can be applied to other governmental agencies to give consistency and uniformity in administration of grants and cooperative agreements.

Betung bamboo (Dendrocalamus asper) is used as a building and handicraft material in Indonesia; however, bamboo needs to be dried to increase its stability. This study aimed to evaluate the efficiency of drying bamboo using solar energy and different drying oven designs. The betung bamboo pieces were dried using a direct solar dryer (direct drying) and an indirect solar dryer (indirect drying) and then the decrease in levels that occurred based on the relative humidity (RH) and temperature values achieved in the two dryers were compared. The highest average temperature in the direct indirect drying oven compartment was 60.1 ± 13.1℃ with 19.9 ± 16.4% RH and 60.2 ± 11.9℃ with 19.5 ± 15.5% RH, respectively. The drying defect in indirect drying was lower than that in direct drying, and indirect drying had a 61.7% greater average water loss than direct drying with significant difference (95%, analysis of variance) based on water loss/compartment volume parameters. Thus, the solar drying oven can be used to air-dry bamboo (14%) for 7 d from an initial moisture content of 70%-80% in bamboo strips. The results of this research can be used for small-scale bamboo processing industries that have limited use of electrical energy with quite good results.

This study is human body measurement of 200 adult males in their 20s by both direct and indirect methods in order to reveal the representative male upper body types. Composition factors of body types were classified while the combination of direct-indirect measurement values was chosen. The following are the findings: 1) The analysis of direct-indirect measurement statistics showed the following results: 173.80cm (height), 69.87kg (weight), 95.58cm (chest girth), $24.67^{\circ}$ (right shoulder angle), and $9.34^{\circ}$ (shoulder width angle). 2) The factor analysis of the body types by direct measurement produced 5 factors: 1 (front length of upper body), 2 (front length of upper body), 3 (back length of upper body), 4 (circumference of upper body), and 5 (shoulders length). These factors accounted for 90.08%. Also, the cluster analysis of factor scores led to 3 types: 1 (33%, short, comparatively wide shoulders and full in the hips), 2 (25.1%, well-developed upper body in tall, inversed triangle), 3 (41%, average height, short upper body). 3) The body-type factor analysis by indirect measurement resulted in 6 factors with the explanation of 83.24%: 1 (rear upper bady thickness), 2 (front upper body width), 3 (front chest thickness), 4 (left-right shoulder angle), 5 (front width of protrusion distance in chest and shoulders), and 6 (neck's front-rear side angle).In addition, the cluster analysis of factor scores brought about 4 types: 1 (15%, well-developed front chest, beardless waist), 2 (23.5%, flat chest, with shoulder, drooping shoulders, strait neck), 3 (39%, with shoulder, curved back), and 4 (22.5%, narrow and thin, curved waist). 4) Among the 118 subjects (75%), 58 subjects commonly appearing in indirect measurement values group and direct measurement values group were chosen the representative body type group according to asterisk indexes. They had the highest frequency in direct type 3 and indirect type 3, whose combination represented the physical characteristics of the representative body types.

Objective: This experiment was conducted as a $3{\times}2{\times}2$ factorial design to examine the effects of particle size (mean particle size of 331, 640, or $862{\mu}m$), evaluation method (direct vs indirect method) and adaptation duration (7 or 26 days) on the energy content and the apparent total tract digestibility (ATTD) of various chemical components in wheat when fed to finishing pigs. Methods: Forty-two barrows ($Duroc{\times}Landrace{\times}Yorkshire$) with an initial body weight of $63.0{\pm}0.8kg$ were individually placed in metabolic cages and randomly allotted to 1 of 7 diets with 6 pigs fed each diet. For the indirect method, the pigs were fed either a corn-soybean meal based basal diet or diets in which 38.94% of the basal diet was substituted by wheat of the different particle sizes. In the direct method, the diets contained 97.34% wheat with the different particle sizes. For both the direct and indirect methods, the pigs were adapted to their diets for either 7 or 26 days. Results: A reduction in particle size linearly increased the digestible energy (DE) and metabolizable energy (ME) contents as well as the ATTD of gross energy, crude protein, organic matter, ether extract (EE) and acid detergent fiber (ADF) (p<0.05), and had a trend to increase the ATTD of dry matter of wheat (p = 0.084). The DE, ME contents, and ATTD of gross energy, crude protein, dry matter and organic matter were higher (p<0.05) when determined by the direct method, but the ATTD of ADF, EE, and neutral detergent fiber were higher when determined by the indirect method (p<0.05). Prolongation of the adaption duration decreased the ATTD of neutral detergent fiber (p<0.05) and had a trend to increase the ATTD of EE (p = 0.061). There were no interactions between particle size and the duration of the adaptation duration. The ATTD of EE in wheat was influenced by a trend of interaction between method and adaptation duration (p = 0.074). The ATTD of ADF and EE in wheat was influenced by an interaction between evaluation method and wheat particle size such that there were linear equations (p<0.01) about ATTD of ADF and EE when determined by the direct method but quadratic equations (p = 0.073 and p = 0.088, respectively) about ATTD of ADF and EE when determined by the indirect method. Conclusion: Decreasing particle size can improve the DE and ME contents of wheat; both of the direct and indirect methods of evaluation are suitable for evaluating the DE and ME contents of wheat with different particle sizes; and an adaptation duration of 7 d is sufficient to evaluate DE and ME contents of wheat in finishing pigs.

Objective: The purpose of the study was to examine the direct effects of parent-adolescent communication and its indirect effects through adolescent friendship quality on happiness among both middle and high school students. Methods: Participants in this study were 1,126 adolescents (667 middle school students and 459 high school students) in Seoul and Gyoung-gi Do. Data were collected through self-report questionnaires for adolescents, which included measures of parent-adolescent communication, friendship quality and happiness. Data were analyzed by t-tests, correlations, and SEM using SPSS 22.0 and Mplus 6.0. Results: For middle school students, father-adolescent communication had direct and indirect effects on happiness. However, mother-adolescent communication did not directly or indirectly affect adolescent happiness. Specifically, only father-adolescent communication had an significant indirect effect through friendship quality on adolescent happiness. For high school students, father-adolescent communication had direct effects on happiness, while mother-adolescent communication had significant indirect effects on adolescent happiness via friendship quality. Conclusion: This study underscores the importance of parent-adolescent communication and friendship quality in predicting adolescent happiness with differences in direct and indirect paths between middle and high school students. These findings emphasize the role of parent-adolescent communication and friendship quality in developing programs to improve the happiness of adolescents.

This study examined the effects of peer relationships, depression, and aggression on bullying and victimization among boys and girls. The subjects were 364 3rd grade students (boys, 218; girls, 146) and 368 6th grade students (boys, 186; girls, 182), that is, a total of 732 students from three elementary schools. Data were collected on bullying, victimization, peer relationships (mutual friendship, mutual antipathy, and peer popularity), depression, and aggression (overt aggression and relationship aggression) from July 12, 2012 to July 13, 2012. These data were analyzed by means of a chi-squared analysis, t-test, and a logistic regression analysis. The results revealed that there were differences by sex in the case of direct bullying and victimization but no differences in the case of indirect bullying and victimization. Among boys, the factors influencing direct bullying were depression and overt aggression, and the factor influencing direct/indirect victimization was depression. Among girls, the factors influencing direct bullying were mutual antipathy relations and relational aggression, the factors influencing indirect victimization were mutual antipathy relations and peer popularity, the factor influencing indirect bullying was mutual antipathy relations, and the factor influencing indirect victimization was peer popularity. The results of this study showed that the factors influencing bullying and victimization are differences in sex. Finally, the implications and methodology for developing bullying prevention education programs were discussed.
