Objective: The purpose of this study was to examine the effects of parental forgiveness and parent-child communication on school-age children's forgiveness in late childhood. Methods: A total of 231 fifth and sixth graders (122 boys and 109 girls) living in Daegu participated in the study. They responded to questionnaires regarding parental forgiveness, parent-child communication and children's forgiveness. The data were analyzed by t-tests, Pearson's correlations, and SEM using SPSS 18.0 and LISREL 9.1. Results: First, paternal forgiveness had a direct effect on children's forgiveness. Second, parental forgiveness had an indirect effect on children's forgiveness through parent-child communication. Finally, multigroup analyses revealed that paternal forgiveness had a direct effect and an indirect effect through father-child communication on boys' forgiveness, whereas maternal forgiveness had an indirect effect on girls' forgiveness through mother-child communication. Conclusion: These findings suggest that the gender of parents and children needs to be considered to explain school-age children's forgiveness. In addition, these findings have implications for future research and practice by highlighting the importance of parental forgiveness and parent-child communication in forgiveness education programs for children and parent education programs.

This study was conducted to investigate a correlation of factors that have an influence on the happiness of college students, and to investigate the effect of factors on happiness of college students by analyzing the structure of influencing factors of happiness. To this end, 430 freshmen in college were selected and tested on character, self-esteem, self-leadership, and happiness. The measurement tools used in this study were the 30 questions of Character Scale that Choi Min-Soo and Im Eun-Young(2013) developed and modified by Im Eun-Young(2015), a Self-Leadership Scale of Manz(1998) classified into behavioral strategy and cognitive strategy that Wang Ji-Seon(2011) translated and modified. a Self-Esteem Scale(SES) of Rosenberg(1986) that the researcher modified and used, and The Oxford Happiness Questionnaire of Hills and Argyle(2002) that Choi Yo-Won(2002) translated and the researcher modified. According to the research result, for correlation with happiness, self-esteem was .86, self-leadership was .74, and character was .66, and for correlation with self-leadership, character was .70, self-esteem was .66, and correlation between character and self-esteem was .57. Secondly, for direct effect on happiness, self-esteem was .62, character as .20, self-leadership was .19, and for direct effect on self-leadership, character was .49 and self-esteem was .38. Thirdly, indirect effect of character on happiness through self-leadership was .94 and indirect effect of self-esteem on happiness through self-leadership was .73. Through these research results, it was identified that character, self-esteem, and self-leadership of college students are the influencing factors on happiness, and that self-esteem is the biggest influencing factor on happiness of college students among the three variables. The results of this study suggested that university students' personality had a positive relationship with self-esteem and that university students' personality, self-esteem, and self-leadership altogether had a direct influence on happiness. Moreover, both personality and self-esteem of university students had an indirect influence on happiness through their self-leadership.

This study examined the effects of eating alone, meal type, and dietary lifestyles on healthy eating capability of one-person households. We analyzed the mediation effects of weekly frequencies of each meal type taken by one-person households between eating habits such as eating alone and dietary lifestyles of one-person households and healthy eating capability. We also analyzed data from the 2019 Food Consumption Behavior Survey using a sample of 688 one-person households. Factor analysis, latent profile analysis, structural equation model analysis was conducted; direct and indirect effects of independent variables were tested using bootstrap method. The major results were as follows. Frequency of eating alone was about 10 times a week on average; one-person households had home-made meals about 12 times a week, for restaurant meals, 4 times, for delivered/take-out food, 0.39 times, and for other types, 0.44 times. Weekly frequencies of eating alone and meal types taken by one-person households were significantly different among the different socio-demographic groups. Dietary lifestyle was classified into four classes: traditional, health ignorant, food lifestyle ignorant, and balanced. Eating alone and dietary lifestyle had a significant effect on weekly frequency of each meal type. Frequencies of eating alone, balanced dietary lifestyle, and taking home-made meals had a positive direct effect on healthy eating capability, and frequency of taking delivered or take-out food and food consumption ignorant lifestyle had a negative direct effect. Eating alone, balanced and traditional dietary lifestyles had a positive indirect effect through the meal type; however, watching Mug-bang had a negative indirect effect.

As in most industrial processes, the dynamic characteristics of an electric power system are subject to changes. Amongst those effects which cause the system to be uncertain, faults on transmission lines are considered. For the stabilization of the power system, we present an indirect adaptive control method, which is capable of tracking a sudden change in the effective reactance of a transmission line. As the plant dynamics are nonlinear, an input-output feedback linearization method equipped with nonlinear damping terms is combined with an identification algorithm which estimates the effect of a fault. The stability of the resulting adaptive nonlinear system is investigated.

Objective: The main purpose of this study was to examine the direct and indirect effects of parent-adolescent communication (through adolescent optimism) on adolescent conflict-coping styles. Methods: A total of 337 high school students participated in this study. They completed questionnaires about communications with their parents and their own optimism and conflict-coping styles. Data were analyzed using t-tests, correlations, and SEM. Results: Neither father- nor mother-adolescent communication had direct effects on adolescent conflict-coping styles. However, mother-adolescent communication had an indirect effect on conflict-coping styles, mediated by adolescent optimism. Adolescents who had open communication with mothers displayed higher levels of optimism, which led to more positive conflict-coping styles. In addition, multigroup analyses revealed that there were significant gender differences in direct and indirect effects. For boys, mother-adolescent communication directly influenced adolescent conflict-coping styles; however, father-adolescent communication did not directly or indirectly affect adolescent conflict-coping styles. For girls, neither father- nor mother-adolescent communication had direct effects on conflict-coping styles; only optimism had a significant effect on conflict-coping styles. Conclusion: The findings from this study suggest that communication with mothers and fathers have different effects on adolescents' conflict-coping styles. These findings have implications for future research and practice by emphasizing the importance of parent-adolescent communication and optimism in designing conflict-coping programs for adolescents.

An one-zone heat release analysis was applied to a 4 cylinder indirect injection diesel engine. The objective of the study is to calculate heat release accurately considering the effect of specific heat ratio. heat transfer and crevice model and to find out combustion characteristics of an indirect diesel engine considering the effect of the pressures in main and swirl chambers. Especially specific heat ratio indicating combustion characteristics is adapted. instead of that indicating matter properties, which has been used in former studies Moreover by adaption of blowby model, cylinder gas mass became accurately calculated. Therefore, with ideal gas equation, calculating cylinder gas temperature, it was found to affect heat transfer loss and heat release. Determining heat transfer constants $C_1$. $C_2$ as 0.6 respectively. the integrated gross heat release values were predicted well for the measured value at various engine speed, full load operating conditions. The curve of heat release rate was similar to SI engine rather than DI engine. That is originated from that swirl chamber reduce an instant combustion which occurs in DI engine due to ignition delay on early stage of combustion.

The purpose of this study was to examine how the career maturity of high school students was affected directly or indirectly by psychological separation from their mothers and through the mediation of self-concept. The subjects in this study were 496 juniors from regular high school in the city of Daegu, who included 243 boys and 253 girls. The measurements of this study were a career-maturity inventory, psychological separation inventory (PSI), and self-concept scale. The major findings of this study were as follows: First, career maturity had significantly positive correlation to conflictual independence from mothers for them. Second, as for the influence of psychological separation, and self-concept on career maturity, three variables, including competence self-concept, home self-concept, attitudinal independence from mothers, classroom self-concept, had significantly explanation of career maturity. Third, as a result of making a path analysis of the impact of psychological separation from mothers on career maturity through the medium of self-concept, conflictual independence gave a direct impact only, and its indirect effect was insignificant. The attitudinal independence showed both direct and indirect influences, for mothers had a significantly indirect impact only.

The exploration of the interaction effect among the components of attractiveness is impossible; therefore, this study uses an indirect estimates approach with multiple scale items that can measure the interaction effect among the components of attractiveness to solve the problem of direct estimates. Previous studies focused on intra-store type competition as their subjects; subsequently, this study dealt with intra-store type competition as well as inter-store type competition in the competing and selecting activities among fashion retailing stores with different business models (such as department stores, road brand stores, discount stores, outlets and internet shopping malls). This study suggests a generalized model for shopping attractiveness of stores and proposes a fashion retailing store type attractiveness (FaRSTA) model instead of a simple relative importance between store selection standards.

[Purpose] The combined effect of different types of post-exercise treatment has not been fully explored. We investigated the effect of combined cold water immersion (CWI) and compression garment (CG) use after maximal eccentric exercise on maximal muscle strength, indirect muscle damage markers in the blood, muscle thickness, and muscle soreness score 24 h after exercise. [Methods] Ten men performed two trials (CWI + CG and CON) in random order. In the CWI + CG trial, the subjects performed 15 min of CWI (15℃), followed by wearing of a lower-body CG for 24 h after exercise. In the CON trial, there was no post-exercise treatment. The exercise consisted of 6 × 10 maximal isokinetic (60°·s^-1) eccentric knee extensions using one lower limb. The maximal voluntary contraction (MVC) and maximal isokinetic (60°·s^-1) strength during knee extension, as well as the indirect muscle damage markers, were evaluated before exercise and 24 h after exercise. [Results] The maximal muscle strength decreased in both trials (p < 0.001), with no difference between them. The exercise-induced elevation in the myoglobin concentration tended to be lower in the CWI + CG trial than in the CON trial (p = 0.060). The difference in the MVC, maximal isokinetic strength, muscle thickness, and muscle soreness score between the trials was not significant. [Conclusion] CWI followed by wearing of a CG after maximal eccentric exercise tended to attenuate the exercise-induced elevation of indirect muscle damage markers in the blood.
