The purpose of this study is to verify the mediating effect of rejection sensitivity and relationship addiction in the relationship between abandonment anxiety and psychological dating violence. For this purpose, data of 400 adult were collected and analyzed, and the structural equations were used to verify them. The measurement tools were the Abandonment Anxiety Scale, the Rejection Sensitivity Questionnaire Scale, Relationship Addiction Questionnaire-30 and Psychological Dating Violence Scale, which were the Revised Conflict Tactics Scales-2 and Appraisal of Partner Control Scale. The results of the study are as follows: First, there was a significant corelation among abandonment anxiety, rejection sensitivity, relationship addiction, and psychological dating violence. Second, there was no direct effect on the relationship between abandonment anxiety and psychological dating violence, but it had an effect on psychological dating violence by double mediating rejection sensitivity and relationship addiction. Based on these results, we confirmed the psychological path that abandonment anxiety affects psychological dating violence, and discussed the need for therapeutic intervention and educational approach in negative interpersonal patterns that are not visible.

This study aims to validate the Korean Student Career Construction Inventory, a translated measure of career adaptation responses, with Korean college students. In order to do so, this study examines the relevant factor structure, internal consistency, test-retest reliability, criterion-related validity and measurement invariance between Korean undergraduate and graduate students. An online survey was completed by 294 participants, including the questions from the translated Korean Student Career Construction Inventory, in addition to measures of career adaptability and vocational identity. One hundred twenty five among the initial participants were tested again in three months for the examination of test-retest reliability. The results supported the four-factor structure of 18 items suggested by the original measure, as well as measurement invariance. The internal consistency and test-retest reliability were adequate. The Korean Student Career Construction Inventory was positively correlated with career adaptability, unidimensional vocational identity, and the dimensions of exploration and commitment of multidimensional vocational identity, but negatively with the dimension of reconsideration. The findings indicate that the Korean Student Career Construction Inventory has psychometric properties similar to the original form and can be used for both undergraduate and graduate students.

The size of state in Korea is like Israel, this country's venture capital is ruled by government. This venture capital's character is below: the concentration on research of venturer affect positively at quality of products. This paper lies with venture capital's risk character & performance. The results show that Korean venture capitals have lager unsystematic risk than systematic risk, which implies they specialize in specific business and/or regional areas instead of diversification. The Sharpe & Jensen measures reveal that the performances of Korean venture capitals are very low relative to even the market portfolio(Kospi) and Kosdaq Venture Index. Contrary to this, Venture firm's performance according to Entrepreneurship will cause to push up stock price.

The purpose of this study was to create and validate Scale of Resilience to Burnout and Scale of Burnout Risk for social workers in medical settings. For the purpose, instrument development model, a kind of mixed methods research was used. In the first phase, six dimensions of resilience(: professional competency, accomplishment and worthwhileness, firm belief and value about their profession, good teamwork, support by their agency, and individual resources) and six dimensions of risk to burnout(: dissatisfaction with organizational condition, interpersonal stress among team members, organizational conflict, work related stress, deficiency of professionalism, and individual stress) were suggested thorough the preceding papers with qualitative approaches. The second phase involved analysis of a survey of 185 participants that appeared to validate the dimensions of the measures. The construct validity and reliability of each measure were tested. And it was founded that there were its own factors in each concept, although resilience to burnout related negatively to burnout risk. The results of this study suggest mixed methods research is useful to develop measures reflecting voices in the social work field.

A new cluster validity index is proposed that determines the optimal partition and optimal number of clusters for fuzzy partitions obtained from the fuzzy c-means algorithm. The proposed validity index exploits an overlap measure and a separation measure between clusters. The overlap measure is obtained by computing an inter-cluster overlap. The separation measure is obtained by computing a distance between fuzzy clusters. A good fuzzy partition is expected to have a low degree of overlap and a larger separation distance. Testing of the proposed index and nine previously formulated indexes on well-known data sets showed the superior effectiveness and reliability of the proposed index in comparison to other indexes.

We propose new metrics for understandability and modifiability of class inheritance structures based on the object-oriented metrics suggested by Chidamber and Kemerer. The metrics are evaluated using the results of Gursaran s experiments which validated the empirical relation of DIT(Depth of Inheritance Tree) and NOC(Number of Children) metrics of Chidamber and Kemerer.

This study examined the relationship between hostility and obsessive-compulsive symptoms to clarify the differential role of overt hostility and covert hostility on obsessive-compulsive symptoms. In addition, this study examined whether impulsivity has a moderating effect on the relationship between hostility measures and obsessive-compulsive symptoms. The Buss Durkee Hostility Inventory (BDHI), Revised Obsessive Compulsive Inventory (OCI-R), and Barratt Impulsivity Scale (BIS) were used to measure hostility, obsessive-compulsive symptoms, and impulsivity, respectively. Data were collected from 150 online university students and analyzed using the correlation and moderated multiple regression model. The result showed that overt hostility was positively correlated with obsessive thoughts; covert hostility was positively correlated with obsessive thoughts and compulsive behavior. In addition, the regression results, which set the hostility variables as the predicting variable, revealed covert hostility to increase obsessive thinking and compulsive behavior, whereas overt hostility had no significant effect on both variables. Impulsivity was found to function as a moderator in the prediction of covert hostility on obsessive thought. With the result, the implications and limitations of this study are discussed.

Bivariate measure of risk and error(BMORE) plot is originally designed to depict bivariate output data and related statistics obtained from a stochastic simulation such as sample mean, median, outliers, and a boundary of a certain percentile of simulation data. When compared to the static numbers, the plot has a big advantage in visualization that enables scholars and practitioners to understand the potential variability and risk in the simulation data. In this study, beyond just the construction of the plot to depict the variability of a certain system, we add a chance constraint to the plot and apply it for decision making such as checking the feasibility of systems, comparing performances of the systems on statistical background, and also analyzing the sensitivity of the problem parameters. In order to demonstrate an application of the plot, we employ an inventory management problem as an example. However, the techniques and algorithms suggested in this paper can be applied to any other problems comparing systems on bivariate performance measures with simulation/experiment results.

Objective：Present study investigated the relationship between mothers' self-perception and perception of children's problems. Method：Subjects were 63 children, mothers, who visited child & adolescent psychiatric clinic. Their mothers completed Minnesota Mulpiphasic Personality Inventory(MMPI) & Korean Personality Inventory for Children(KPI-C). Correlation between validity scales of mothers' MMPI and validity scales of KPI-C was analysed, and then we divided subjects into two group(High & Low Group) according to the MMPI validity scales, and compared KPI-C's validity scales by student t-test. Result：There were significant positive correlation(r=.30) between K scale of MMPI and L scale of KPI-C, significant negative correlation(r=-.32) F scale of MMPI and L scale of KPI-C. The Means of T scores did show significant difference according to MMPI F, K scales in KPI-C L scale, to MMPI L scale in KPI-C F scale. Conclusion：These results indicated that defensive mothers tend to perceive her child's problems more defensively. However mothers who exaggerate their problem more severely, do not exaggerate their children's problem. Therefore, these result suggested that we should be careful not to underestimate children's problem whose mother elevated in K scale of MMPI.

In this study, a Korean abbreviation scale to measure love and compassion toward other person was developed based on a critical review on Compassionate Love Scale(CLS; Sprecher, & Fehr, 2005). In the study 1, 12 items were selected from the original version of 21 item CLS by surveying a sample of 207 college students on the basis of several psychometric characteristics (i.e., discriminability, coefficient of factor loading, and contribution to internal consistency). In the study 2, the validity of 12 item version, ACLS (Ajou Compassionate Love Scale), was confirmed by examining the factor structure, reliability, and correlations with other related scales. The results clearly showed that ACLS not only had a sufficient psychometric properties as the CLS, but also superior to the CLS in terms of parsimoniousness. Limitations and implications for future research of ACLS were discussed.
