Skin condition is an important concern in beauty aspect. This study considered a rough skin condition analysis method that beauty industry workers can do through visual observation or skin condition images taken with smartphones. First, studies that combine subjective and objective evaluations were selected among degree papers and academic papers searched by keywords related to 'skin condition' in the Research Information Sharing Service(RISS). Among them, papers that derive correlations with visually verifiable factors were selected. Next, the relationship between factors that match subjective skin condition and objective skin measurement results and factors that can be visually identified on the skin surface was investigated. According to the study, the most suitable factor for matching subjective and objective evaluations was 'oil volume', which is significantly related to 'pore', 'skin texture' and 'erythema', which can be visually checked on the skin surface. It is believed that a rough skin condition analysis will be possible using this.

The number of variables exceeds the number of samples in microarray data. We propose a nonparametric local linear logistic classification procedure using orthogonal components for classifying high-dimensional microarray data. The proposed method is based on the local likelihood and can be applied to multi-class classification. We applied the local linear logistic classification method using PCA, PLS, and factor analysis components as new features to Leukemia data and colon data, and compare the performance of the proposed method with the conventional statistical classification procedures. The proposed method outperforms the conventional ones for each component, and PLS has shown best performance when it is embedded in the proposed method among the three orthogonal components.

The purpose of this study was to develop an empirically-based inventory of organizational innovativeness of social welfare organizations. Review of literature on innovation research and panel study resulted thirty-seven(37) pre-items for measuring organizational innovativeness. An exploratory factor analysis of the pre-items drawn from the first survey data of 178 social workers revealed seven(7)-factor structure of 31 items. The factors included leadership innovation, team work innovation, task innovation, program development innovation, program technology innovation, idea innovation. A confirmatory factor analysis using data from the second survey of 409 social workers also indicated relevance of seven(7) factor structure of the inventory. Further these seven factors showed positive and significant correlations with measures for innovation culture indicating the inventory had the criterion-related validity. Although additional work remains in methodological issues, the results presented in this paper have shown that this inventory of organizational innovativeness can be an useful tool for assessing innovativeness of social welfare organizations.

The aim of the study is to develop the Adolescent Anger Provocation Scale(AAPS) for Korean adolescents. In order to develop the scale, two research processes were conducted. First, a total of 130 items were derived from various related research. After analyzing 130 items by a research team(2 related field professors and 2 Ph.D. students), a total of 54 items reconstructed based on redundancy, cultural relevancy, and appropriateness. Second, a survey was administered among 252 Korean adolescents. After analyzing an exploratory factor analysis, 12 items of poor factor loading were deleted. Thus, seven factors and 42 items were extracted. Seven factors were as follows: (1) threat to self-esteem, (2) uncontrollable situations, (3) violation of personal property, (4) incidents associated with rejection, (5) violation of regulation or rules, (6) disrespectful treatment, (7) unfair treatment due to age. The internal consistency and convergence validity of the scale were supported. The results of confirmatory factor analysis were also reported. In addition, study limitations and recommendations of future research were discussed.

Economic factors are important in improving life satisfaction of disabled people. In addition, the impact of job satisfaction on life satisfaction has been verified. However, according to Herzberg's motivation-hygiene theory, hygiene factors such as wages only lowers dissatisfaction and does not directly affect job satisfaction. This study raises questions about Herzberg's theory and seeks to confirm through empirical analysis. Based on data from the 2017 Employment Panel Survey for the Disabled, this study seeks to answer analyzes whether hygiene factors proposed by Herzberg affect the job satisfaction of disabled people or not. Furthermore, this study proposes what regional policies are needed to enhance job satisfaction for the disabled. An analysis of structural equation model showed that hygiene factors such as working environment, interpersonal relationship and personal life directly affect the disabled worker's job satisfaction. In addition, through hierarchical linear model analysis, it was confirmed that local governments ought to provide education supports to the disabled workers in order to improve their job satisfactions.

This study is to evaluate the effectiveness of problem-solving ability by applying a team-based learning model to the classes of humanities and social science students, and to conduct a structural model analysis on the relationship between sub-factors. Team-based learning was conducted six times in six teams with 30 students in the second and third grades of the humanities and social sciences. The problem solving ability score of the target students was significantly higher after team-based learning and was statistically significant. There was no problem in normality with the latent variables, which are the sub-factors of problem solving ability, and the factor load value was statistically significant at the .001 level in the confirmatory factor analysis of the observed variables for the latent variables, which was a valid model. A good level of fitness was also shown in the verification of the fitness of the research model. As a result, it was analyzed that latent variables of cause analysis, problem clarification, planning execution, performance evaluation, and alternative development had an indirect or direct influence on each other.

The unexpected increase of violent crimes in Korea urges people to look for more dynamic explanations of criminal behavior other than sociological eugenics such as a struggle between social classes or assimilation to deviant social environment. In this study, criminal behavior is treated as personal matter according to the tradition of psychological theories of crime rather than sociological phenomenon. Furthermore, aggression is supposed to be one of the most basic dispositional characteristics of violent acts. Therefore, this study explored the relationship between aggression measured by BPAQ and criminality evaluated based on seriousness of criminal offenses. On the other hand, the cross-validity of BPAQ was also investigated since prevalence and expressive forms of violence is known to vary across cultures and even within a society. The variance analyses and causal modeling presented that BPAQ had satisfactory level of cross-validity and dispositional aggression measured by BPAQ might have causal effect on criminality of Korean offenders. Additionally, a theoretical internal structure of BPAQ had been confirmed to be reasonable by confirmatory factor analyses.
