Despite the recent sharp growth in the baby product market, previous studies on preschooler clothing have centered primarily on surveys regarding body size and consumer buying behavior, with little emphasis given to consumption value in preschooler clothing. This study aimed to assess the feasibility of using standards of consumption value to examine the behavior of those who buy preschooler clothing. The research subjects were mothers of preschoolers aged 1 to 6 years. They were asked to complete a questionnaire online at major parenting blogs found on portal sites (n=346). The questionnaire contained 41 questions based on a literature review, and 25 questions having convergent and discriminant validity were analyzed. By conducting a regression analysis of standards of consumption value in preschooler clothing and their perceived value, the feasibility of the standards was assessed. The results showed that consumption value in preschooler clothing was associated with 21 questions and 8 factors. The factors measuring consumption value included vicarious satisfaction, social value, functional value, convenience, financial value, aesthetic value, uniqueness, and circumstantial value. This study is significant in that it expands the scope of research on preschooler clothing, lays the groundwork for measuring consumption value in preschooler clothing, and predicts consumer behaviors by identifying the consumption value among mothers of preschoolers.

The primary aim of this study is to develop a three dimensional finite element (FE) model to predict the axial stress-strain relationship and ultimate strength of the FRP-wrapped UHPC columns by comparing experimental results. The reliability of four selected confinement models and three design codes such as ACI-440, CSA-S806-02, and ISIS CANADA is also evaluated in terms of agreement with the experimental results. Totally 6 unconfined and 36 different types of the FRP-wrapped UHPC columns are tested under monotonic axial compression. The values of ultimate strengths of FRP-wrapped UHPC columns obtained from the experimental results are compared and verified with finite element (FE) analysis results and the design codes mentioned above. The concrete damage plasticity model (CDPM) in Abaqus is utilized to represent the confined behavior of the UHPC. The results indicate that agreement between the test results and the non-linear FE analysis results is highly satisfactory. The CSA-S806-02 design code is considered more reliable than the ACI-440 and the ISIS CANADA design codes to calculate the ultimate strength of the FRP-wrapped UHPC columns. None of the selected confinement models that are developed for FRP-wrapped low and normal strength concrete columns can safely predict the ultimate strength of FRP-wrapped UHPC columns.

The current study presents experimental and numerical results on the effect of ultrasonic vibrations on a cylindrical cup drawing of a cold rolled steel sheet(SPCC). An experimental apparatus, which can superimpose high frequency oscillations during deep drawing, was constructed by installing on the tooling ultrasonic vibration generators consisting of a piezoelectric transducer and a resonator. Conventional and vibration-assisted cylindrical deep drawing tests were conducted for various drawing ratios, and the limiting drawing ratios(LDR) for both methods were compared. To evaluate quantitatively the contribution from the ultrasonic vibrations to the reduction of friction between tools and material finite element analyses were conducted. Through a series of parametric analyses, the friction coefficients, which minimized the differences of punch load data between the experiments and simulations, were determined. The results show that the application of ultrasonic vibration effectively improves the LDR by reducing the friction between the tools and the material.

This research focuses on the analysis of factors affecting the market share of retailers in Vietnam. This research uses Smith and Chaffey's (2005) 5Ss e-marketing model for analysis, which include Sell, Serve, Speak, Save, and Sizzle. Both quantitative and qualitative methods will be used to conduct the study. The researchers collected information from customers, managers, and directors in 25 retailers in Vietnam. A survey questionnaire was delivered to 15 people in each of the retailers who are customers, managers and directors. The researcher used the SPSS 16.0 software to analyze the data collected and in-depth interviews were carried out with the purpose of testing the hypothesis as well as the overall framework of the research. Out of the 375 questionnaires delivered, 360 were returned. The means of 23 items in the survey questionnaire ranged from 3.3733 to 4.3533 representing the outcome of the descriptive analysis. Research results showed that Cronbach's Alpha coefficient of five factors affecting the market share of the retailers is sizzle, save, sell, serve and speak. This research has proposed some implications for the market share of retailers, including technology enhancement for full message delivery, ways to approach target customers, and improving product diversity.

본 연구는 게임 콘텐츠에서 맹승(盲僧) 캐릭터의 활용 가능성을 모색하고, 그 방안에 대해 제시하는 것을 목적으로 삼는다. 이를 위해 맹승에 관한 문헌 기록을 바탕으로 역사적 변천 과정을 검토하였으며, 한국 문화에서 맹승이 갖는 역사적·문화적 위상을 고찰하였다. 이를 토대로 게임 콘텐츠에서 문화원형으로서 맹승 캐릭터의 가치와 활용 가능성을 검토하고 맹승이 가지고 있는 민속문화적 특징에 따라 캐릭터 창작의 기본 구성 요소를 제안하였다. 그 구체적 내용으로는 맹승 캐릭터 디자인을 할 때 안맹(眼盲)과 개안(開眼) 요소라는 외적 특징과 문무를 겸비한 내적 특징을 결합해야한다고 보았다. 또 맹승에 관한 역사적 기록을 바탕으로 ARPG 장르 게임에서 맹승 모티브를 다루는 게임의 스토리텔링과 메커니즘에 대해 제언하였다. 이러한 연구는 문화원형으로서 맹승 활용 가능성을 모색했다는 점에서, 이를 통해 한국 게임 콘텐츠 기획 및 창작 방법에 있어 단초를 제공할 수 있을 것이다.

Box-Cox power transformation is employed for analyzing volatilities in Korean financial time series such as KOSPI, KOSDAQ index and interest rates. Statistical procedures for Box-Cox transformed ARCH models are presented. For illustration, diverse financial time series data are analyzed and appropriate power transformations are suggested for each data.
