The purpose of this study was to investigate the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles. The subjects were 399 middle school students and 366 high school students in four middle schools and two high schools in metropolitan and small towns for one month from July 1, 2017. Data were analyzed through descriptive statistics, correlation analysis. Multiple regression was used to see how parent-adolescent communication styles, self esteem, and depression affect the career decision-making style. As a result, first, open communication with mothers has a statistically significant effect on the rational career decision-making style and open communication with fathers has a statistically significant effect on the intuitive career decision-making style of adolescents. Second, self-esteem of adolescents showed a positive correlation with rational career decision-making style and negative correlation with dependent career decision-making style, and depression showed a positive correlation with dependent career decision-making style. The results may help to understand the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles and be used for counseling intervention.

The purpose of this study was to investigate the relationship between college students' work hope, career attitude maturity and career decision-making self-efficacy. For this, correlation analysis, variance analysis and multiple regression analysis were conducted using 299 data collected from 8 universities in the metropolitan area, Yeongnam, Honam, Gangwon and Chungcheong provinces. As a result of correlation analysis between work hope and career variables, there was a positive correlation between r=.64 and .73 in each sub-factor. After performing a variance analysis to explore the differences in work hope between gender, grades and major fields, there were no gender and grade differences found, but there were significant differences between major fields. Also, as a result of multiple regression analysis, it was found that work hope affecting career attitude maturity was pathways, and in career decision-making self-efficacy, agency, pathways thinking, and goal were influenced. On the analysis result, the limitations and implications of this study were discussed using college students' work hope scale.

The increasing complexity of the socio-economic environments makes it less and less possible for single decision-maker to consider all relevant aspects of problem. Therefore, many organizations employ groups in decision making. In this paper, we present a multiperson decision making method using fuzzy logic with linguistic quantifier when each of group members specifies imprecise judgments possibly both on performance evaluations of alternatives with respect to the multiple criteria and on the criteria. Inexact or vague preferences have appeared in the decision making literatures with a view to relaxing the burdens of preference specifications imposed to the decision-makers and thus taking into account the vagueness of human judgments. Allowing for the types of imprecise judgments in the model, however, makes more difficult a clear selection of alternative(s) that a group wants to make. So, further interactions with the decision-makers may proceed to the extent to compensate for the initial comforts of preference specifications. These interactions may not however guarantee the selection of the best alternative to implement. To circumvent this deadlock situation, we present a procedure for obtaining a satisfying solution by the use of linguistic quantifier guided aggregation which implies fuzzy majority. This is an approach to combine a prescriptive decision method via a mathematical programming and a well-established approximate solution method to aggregate multiple objects.

The AHP methodology compares criteria, or alternatives with respect to a criterion, in a natural, pairwise mode. AHP has been applied in a wide variety of applications multi objective decision making being just one. If a group of expert with different aspect, they need some way to revise expert group. We proposed the concatenation of expert to survey the AHP pairwise question for multi-attribute decision making. In this paper, we suggest a way to revise the expert's priorities in hierarch using concept of different group opinion.

Recently, multiple criteria decision making has been well established as a practical approach to seek a satisfactory solution to a decision making problem. Goal programming is one of the most powerful MCDM tools with satisfying operational assumptions that reflect the actual decision making process in real-world situations. In this paper we propose an efficient method implemented on a microcomputer for solving linear goal programming problems. It is an iterative revised goal simplex method using the sparsity technique. We design as interactive software package for microcomputers based on this method. From some computational experiences, we can state that the revised iterative goal simplex method using the sparsity technique is the most efficient one for microcomputer for solving goal programming problems.

Wrinkle and fracture are two major defects frequently found in the sheet metal forming process. In this process there are more than one design attributes to optimize and several uncontrollable factors which cannot be ignored in determining the optimal values of design variables. Therefore, attempts to reduce defects through a traditional optimization technique are often led to failures. In this research, a new design method for reducing the wrinkle and fracture under uncontrollable factors is presented by using decision-making theory. To avoid the psychological difficulties in determining the scaling constants of the multi-attribute utility function by using the ordinary lottery questions, a pair-wise comparison procedure is adapted to avoid this problem. The effectiveness of the proposed method is illustrated through a robust design of sheet metal forming process of a side member of an automotive body.

This study examined the effects of courage on happiness and the mediating effects of the decision making ability on the relationship between courage and happiness. The courage Inventory for Young Children (Park & Lee, 2011), The Children's decision making ability Scale (Park, 2012) and the happiness Questionnaire (Kim, 2008) were administered to 220 young children (112 boys, 108 girls, 5 year of age). The collected data were analyzed by descriptive statistics, Pearson's correlation analysis, multiple regression analysis, and a sobel test using the computer program, SPSS/PC 21.0. The results were as follows. First, there were significant positive relationships among courage, decision making ability, and happiness. Second, courage was an important factor in predicting the happiness of young children, and the decision making ability had mediating effects on the relationship between courage and happiness.

The purpose of this study was to identify the influences of psychological independence(functional independence and emotional independence) and career decision-making self-efficacy(self-estimation, career goal, occupational-knowledge, and problem solving) on career maturity(preparation, objective, decisiveness, and certainty) among adolescents. The subjects were 447 students in the second grade of middle school and high school in D. The questionnaire consist of measures of psychological independence, career decision-making self-efficacy, and career maturity. The data were analysed with factor analysis, Cronbach's ${\alpha}$, t-test, ANOVA, correlation and multiple regression by using the SPSS(SPSS/WIN 19.0) program. The major results were as follows. First, adolescents' the career maturity was significantly different depending on the socio-demographic variables. Second, it was shown that middle and high school students have a statically relation, in a relation among psychological independence, career decision-making self-efficacy, and career maturity. Third, it was found that psychological independence and career decision-making self-efficacy gave statistically meaningful influence on the career maturity of adolescents. This study is significant in that it suggests a plan for improving career maturity, and provides a basic material to improve one's active role in their parents. In addition, the results of this study can be used as a fundamental reference in career development programs and career-counseling centers at schools for enhancing adolescents' career development and success.

This study examined the effects of ego-resilience, critical thinking disposition, and self leadership on the career decision-making self-efficacy among nursing students. Undergraduate nursing students (N=341) were sampled randomly from nursing departments in two cities. Data collection was conducted from May 11 to June 5, 2015. The participants completed a questionnaire assessing the ego-resilience, critical thinking disposition, self leadership, and career decision-making self-efficacy. The data were analyzed with descriptive statistics, t-tests, ANOVAs, Pearson's correlations, and multiple regression. Career decision-making self-efficacy was varied by application motivation, satisfaction with one's major, personality traits, and interpersonal relationship; Self leadership was the most influential factor predicting the career decision-making self-efficacy, followed by critical thinking disposition, and satisfaction with one's major and personality traits. Therefore, these results highlight the need to devise an appropriate program to improve self-leadership and critical thinking, which will contribute to the career-related behaviors of nursing students.

Purpose: The aim of this study was to determine whether job-seeking stress, career decision-making self-efficacy, self-esteem, and academic achievement had an influence on nursing students' happiness. Methods: The participants were 147 nursing students in D city. Data were collected with a structured questionnaire. The data were analyzed with SPSS/WIN 19.0 using ANOVA, t-test, Pearson correlation, and stepwise multiple regression. Results: Factors that had an influence on happiness included major satisfaction(highly unsatisfied ${\beta}=-.251$, p=.001), average monthly family income(between four and six million won ${\beta}=.222$, p=.002), career decision-making self-efficacy(${\beta}=.198$, p=.010), major satisfaction(satisfied ${\beta}=.196$, p=.006), and subjective health(unhealthy ${\beta}=-.167$, p=.020). These factors explained 33.5% of the variance in student happiness. Conclusion: The results of this study reveal that career decision-making self-efficacy, self-esteem, major satisfaction, and job-seeking stress were important intrinsic factors in the happiness of nursing students. Thus, it is necessary to help these students attain more self-efficacy, self-esteem, and major satisfaction rather than focusing on academic achievement in order to increase their happiness.
