Outsourcing enables firms to use external resources in efficient and effective manner by adopting the best practice of industry. It also helps firms improve their business process which may result in seizing or creating new business opportunity. Collaborating with outstanding BPO(business process outsourcing) providers offer a great deal of advantage that could access to new knowledge, technology, intellectual and material resources that firms do not own. This study was designed to provide in-dept understanding of key elements that may affect the attitude towards BPO of entrepreneurs using 99 samples comprised SME & Venture business owners. Specifically, this study aims to test and analyse the relationship between attitude towards BPO and 4 independent variables including cost reduction, core competence, specialized resources and quality improvement. The analysis results show that core competence, specialized resources and quality improvements have all positive relationships with the attitude towards BPO. However, exceptionally cost reduction is not associated positively with the attitude towards BPO which was against our expectation. Theoretical discussion and practical implication on the analysis results are provided.

The quantitative landslide susceptibility assessment methods can be divided into statistical approaches and geomechanical approaches based on the consideration of the triggering factors and landslide models. The geomechanical approach is considered as one of the most effective approaches since this approach proposes physical slope model and considers geomorphological and geomechanical properties of slope materials. Therefore, the geomechanical approaches has been used widely in landslide susceptibility analysis using the infinite slope model as physical slope model. However, the previous studies assumed constant groundwater level for broad study area without the consideration of rainfall intensity and hydraulic properties of soil materials. Therefore, in this study, landslide susceptibility assessment was implemented using the coupled infinite slope model with hydrologic model. For the analysis, geomechanical and hydrualic properties of slope materials and rainfall intensity were measured from the soil samples which were obtained from field investigation. For the practical application, the proposed approach was applied to Jinbu area, Gangwon-Do which was experienced large amount of landslides in July 2006. In order to compare to the proposed approach, the previous approach was used to analyze the landslide susceptibility using randomly selected groundwater level. Comparison of the results shows that the accuracy of the proposed method was improved with the consideration of the hydrologic model.

The purpose of this study was to examine the effect of the actor and partner effects of the parental sex-role attitude on the parent-child relationship by using the Actor-Partner Interdependence Model (APIM). Specifically, this study focused on the examination of the actor and partner effects of the parental sex-role attitude in married couples with immigrant women who have children under 5 years old. For the analyses, a total of 5,531 couples who participated in the National Survey on Multi-cultural Families were included and the major findings are as follows. First, the couple's sex-role attitude had a statistically significant actor effect on the parent-child relationship. Parents who were more conscious of gender equality displayed a better parent-child relationship and this effect was greater in the case of the father's attitude than the mother's. Second, the father's sex-role attitude had a statistically significant partner effect on the mother-child relationship, whereas the mother's attitude did not. Third, the couple's actor effects were greater than their partner effects and this means that the personal sex-role attitude has a greater impact on the parent-child relationship than the partners' attitude. The implication and limitations derived from these empirical-scientific database results and related studies in educational program of gender equality attitude for multi-cultural families.

The purpose of the study is to develop a questionnaire that examines unskeptical attitudes in scientific inquiry context. The questionnaire items were developed through literature research, expert review, and statistical analyses for validity and the differences in scores were identified by gender and tracks. A total of 363 high school students participated in the study. To explore the validity evidence of items, the Rasch analysis and the reliability of internal consistency were performed, and the two-way ANOVA was performed to compare the scores of the unskeptical attitudes between gender and academic track. Self-reporting and Likert-scaling 23 items were developed to measure unskeptical attitudes in scientific inquiry context. The items were developed in the sub-domain of scientific inquiry: 'questioning and hypothesis generating,' 'experiment designing,' and 'explaining and interpreting.' Second, the validity and reliability of the unskeptical were identified in a rigorous method. The validity of items were identified by multi-dimensional partial score model analysis through the Rasch model, and all 23 items were found to be fit to model. Various reliability evidences were also found to be appropriate. It was found that there were no significant differences of unskeptical attitude score between the gender and academic track except one comparison. The developed questionnaire could be used to check an unskeptical attitude in the course of scientific inquiry and to compare the effects of scientific inquiry classes.

Recently, landslide and debris-flow disasters caused by severe rain storms have frequently occurred. Many researches related to landslide susceptibility analysis and debris-flow hazard analysis have been conducted, but there are not many researches related to mobilization analysis for landslides transforming into debris-flow in slope areas. In this study, statistical analyses such as discriminant analysis and logistic regression analysis were conducted to develop a mobilization criterion using geomorphological and geological factors. Ten parameters of geomorphological and geological factors were used as independent variables, and 466 cases (228 non-mobilization cases and 238 mobilization cases) were investigated for the statistical analyses. First of all, Fisher's discriminant function was used for the mobilization criterion. It showed 91.6 percent in the accuracy of actual mobilization cases, but homogeneity condition of variance and covariance between non-mobilization and mobilization groups was not satisfied, and independent variables did not follow normal distribution, either. Second, binomial logistic analysis was conducted for the mobilization criterion. The result showed 92.3 percent in the accuracy of actual mobilization cases, and all assumptions for the logistic analysis were satisfied. Therefore, it can be concluded that the mobilization criterion for debris-flow using binomial logistic regression analysis can be effectively applied for the prediction of debris-flow hazard analysis.

This study introduced the components of apparel store, which include product and service factor to reflect the modified conception of service. The purposes of this study were to investigate the dimensions of the components of apparel store and to examine consumers' rating of importance on the components of apparel store. In addition, this study explored the effect of clothing involvement and demographic variables on importance perception. Data were collected via a questionnaire from young adult females in their twenties. The results of this study revealed five dimensions of service factor: environmental service, salesperson service, attitude and policy service related to exchange and refund, policy service related to promotion, and policy service related to convenience. Factors related to product were identified price, quality, variety, fashion, design and brand. Attitude and policy service related to exchange and refund is the most important factor that consumer perceived. Salesperson service and product quality were the second important factors. The relatively important factor in each service dimension was this : display in the environmental service, the ability of salesperson to resolve customer's complaints in the salesperson service, sales person’s courtesy in managing exchange or refund in policy service. Clothing involvement and demographic variables do affect consumers’perception on importance.

The purpose of this study was to develop and validate a mathematics anxiety scale for elementary students in South Korea. Based on the literature review, I developed two types of survey items measuring elementary students' mathematics anxiety. Teachers or students may use survey measurements selectively according to the students' participants in mathematics private institutions. In order to assess the reliability and validity of survey items, I conducted surveys with elementary students. The sample consisted of 300 elementary students in public elementary schools in Seoul. A total of 28 items were developed and examined for the internal consistence. The results showed that the proposed scale was appropriate to represent the mathematics anxiety of elementary students. The survey items of this study could be applied for assessing elementary students' mathematics anxiety regardless of their gender and age factors.

To examine the sex morph, fruiting characteristics and seed viabilities of Acer palmatum var. matsumurae (Koidz.) Makino, the flowers and seed-sets of 101 trees were collected from early April to late October 2010, and floral structure and seed viability were studied. Among investigated 101 trees, 73.3% of trees were protandrous (PA: pollen is shed before stigmas are receptive) and 26.7% were protogynous (PG: stigmas are receptive before pollen is shed). Acer palmatum var. matsumurae has heterodichogamous sexual system. Number of flowers and seed-sets per inflorescence are significantly different between sex morphs, and PA has more flowers and seed-sets per inflorescence than PG. Rates of sound seeds and decayed seeds are significantly different between sex morphs. Rates of sound seeds were 46.4% in PA, but 65.6% in PG. and rates of decayed seeds were 49.6% in PA, but 23.6% in PG. The differences of decayed seeds' rates between sex morphs might be related with the timing of pistil flower blooming and insect pests' outbreak.
