This study integrated mother's control behavior of child's misbehavior within social domain analysis and the framework of attributional models of social cognition. The purpose of this study was to identify, compare and contrast maternal attributions and control responses according to child's age and domains of social behavior, and to investigate that mother's social cognition factors(authoritarian attitude and self competence perception) influence material inference and responses for their child's acts. Then this study was to find out whether mother's attribution would mediate their socialization techniques. For empirical research, 654 mothers with 5.6 year old and 8.9 year old children as subjects answered the structured questionnaire. The data were analyzed by frequencies, t-test, oneway ANOVA, and multiple regression. The major findings were as follows: First, according to child's two domains of misbehavior, there were differences in mothers'attribution and control behavior. Also mothers regarded older child's behavior as more dispositional cause and as more deserving of punishment than younger child's. Second, mother's authoritarian altitude of parenting, self-competence perception, and educational level were significantly related to mother's judgment. Third, the more authoritarian attitude mothers had, the more dispositional factor of children they attributed. And the lower self-competence mothers perceived. the more internal factor of child they attributed. Finally, maternal attributions and control responses are interrelated. When they attributed their children's misdeeds to internal dispositions, they respond with more stronger control behavior. The results suggested maternal social cognition mediate socialization behavior.

Purpose The purpose of this study is to build a machine learning-based customer classification model to promote customer expansion effect of the free sample promotion. Specifically, the proposed model classifies potential target customers who are expected to purchase the products included in the free sample promotion after receiving the free samples. Design/methodology/approach This study proposes to build a customer classification model for determining customers suitable for providing free samples by using various machine learning techniques such as logistic regression, multiple discriminant analysis, case-based reasoning, decision tree, artificial neural network, and support vector machine. To validate the usefulness of the proposed model, we apply it to a real-world free sample-based target marketing case of a Korean major cosmetic retail company. Findings Experimental results show that a machine learning-based customer classification model presents satisfactory accuracy ranging from 70% to 75%. In particular, support vector machine is found to be the most effective machine learning technique for free sample-based target marketing model. Our study sheds a light on customer relationship management strategies using free sample promotions.

In the design of structure the forces acting on the structure are important parameter for noise and vibration control. However, in the complex structure, the forces at the injection pomt on the structure cannot be measured directly. Thus it is necessary to find out indirect force evaluation method. In thls paper forces have been measured with in-situ vibration responses and system information. Three existing techniques of indirect force measurement, viz. direct inverse, principal component analysis and regularization have been compared. It has been shown that multi-vibration responses are essential for the precise estimation of the forces. To satisfy those cond~tions, Rotary compressor is adopted as test sample, because it is very difficult to measurc the injection forces from internal excitat~on to shell. It has also been obtained that relatively higher force IS transmitted through three welding paths to the compressor shell. It shows a good agreement between direct and indirect force evaluation wlth curvature shell and plate and is investigated the possibility of force evaluation of rotary compressor as a complex structure.

Purpose: The purpose of the study was to examine the impact of self-efficacy in the prevention of sexually transmitted diseases (STD), knowledge of and susceptibility to STD, and the role of gender in sexual autonomy. Methods: Data were collected from 267 college students using self-report questionnaires during the period from the first to the twentieth of June 2015. Data were analyzed using $x^2$ test, Fisher's exact test, t-test, Pearson correlation coefficients, simple and multiple regression techniques with the PASW/WIN 20.0 program. Mediation analysis was performed according to the Baron and Kenny method and Sobel test. Results: In male students, self-efficacy for STD prevention showed a full mediating effect in the relationship between STD susceptibility and sexual autonomy (${\beta}$=-.08, p=.370). But in female students, it had a partial mediating effect (${\beta}$=-.25, p=.001). And self-efficacy for STD prevention showed partial mediating effects in the relationship between knowledge of STD and sexual autonomy in the both male (${\beta}$=.25, p=.005) and female students (${\beta}$=.33, p<.001). Conclusion: To enhance college students' sexual autonomy, it may be useful to build effective strategies enhancing students' knowledge about and susceptibility to STD and to develop a self-efficacy promotion program for college students.

수치해법와 경험적 방법을 합성함으로써 하천수문곡선의 기저유출을 분리하는 방법을 개발하였다. 기저유출 감수곡선에 대해서는 선형화된 Boussinesq 방정식과 저유함수를 적용하였으며, 또한 강우에 의하여 지하의 대수층에 침투된 량이 하천으로 유입되는 기저유출의 추정에는 Singh과 Stall의 도식적 방법을 이용하였다. 이들에대한 시간별 연속성은 다원적인 다항식 회귀론에 의하여 근사화시켰다. 본 연구과정은 자연하천에 성공적으로 적용할 수 있었으나, 감수곡선을 위한 동차선형2단상징분계의 직접적 수치해법은 부적합한 것으로 나타났으며, 손실이 발생되는 부분침투천의 기저유량은 본 연구방법에 의하여 추정할 수 없었다.

Purpose - This study aims to investigate domestic wine consumption behavior and make future sales strategies and marketing plans. Research design, data, and methodology - To achieve the purpose of the study, the surveys were conducted targeting 350 wine customers in Jeju and Seoul. 331 responses were collected, and out of them, 21 responses were deleted because they lacked the proper information fill in. A descriptive statistical analysis was applied to the remaining 310 responses. The statistical techniques used for carrying out hypothesis-testing are EFA_(exploratory factor analysis), multiple-regression analysis, and moderating effect in SPSS 18.0. Results - The results indicate that fashion oriented, sociality aspiration and rationality seeking lifestyles had significant influence upon internal attributes. However, well-being oriented and having enjoyment oriented lifestyle had no significant influence upon internal attributes. Furthermore, all the types of lifestyles except social aspiration lifestyles had a positive influence upon external attributes, whereas internal or external attributes had positive influence on customer satisfaction. Conclusions - The consumers who experienced wine purchases think wine selection attributes differ before and after experiencing wine drinking, and it shows that the circumstantial variables as purchase situations prove to be important predicted variables in the behavior field of wine consumers. It implies appropriate wine education according to the consuming trend about wine for wine consumers are needed.
