The objective of this study was to develop evaluation criteria for forest education using the Context, Input, Process, and Product (CIPP) model. To this end, we designed a survey based on expert advice and content analysis of previous studies on the CIPP model and forest education. The survey was conducted on 393 forest education specialists, and Cronbach's α coefficient was set as 0.6 or higher to verify reliability and validity, and to determine reliability by factor. Eventually, 52 out of 57 evaluation items were extracted, and the evaluation indexes were selected through factor analysis as follows: four evaluation indexes for the context dimension, namely "Clarity of goal setting," "Developing conditions for education," "Meeting of requirements," and "Institutional drive"; three evaluation indexes for the input dimension, namely "Acquisition of education infrastructure," "Establishment of operational support," and "Adequacy of assigned manpower"; four evaluation indexes for the process dimension, which were "Adequacy of budget allocation," "Expertise of forest education instructors," "Diversity of programs," and "Public-private academic partnership"; and five evaluation indexes for the product dimension, namely "Effectiveness of perception change," "Influence over the society," "Continuity of improvement in evaluation," "Continuity of education," and "Verification of the effects of education."

The purpose of this study was to develop an assist device that could correct and support patient position during biopsy on computed tomography (CT) using 3D printing technology. The development method was conducted in the order of 3D design, 3D output, intermediate evaluation for product, final assist device evaluation. The 3D design method was conducted in the order of prior research data survey, measurement, primary modeling, 3D printing, output evaluation, and supplementary modeling. The 3D output was the 3D printer (3DWOX 2X, Sindoh, Korea) with additive manufacturing technology and the polylactic acid (PLA) materials. At this time, the optimal strength was evaluated to infill degree of product as the 3D printing factors into 20%, 40%, 60%, and 80%. The intermediate evaluation and supplementation was measured noise in the region of interest (ROI) around the beam hardening artifact on the CT images. We used 128-channel MDCT (Discovery 75 HD, GE, USA) to scan with a slice thickness of 100 kVp, 150 mA, and 2.5 mm on the 3D printing product. We compared the surrounding noise of the final 3D printing product with the beginning of it. and then the strength of it according to the degree of infill was evaluated. As a result, the surrounding noise of the final and the early devices were measured at an average of 3.3 ± 0.5 HU and 7.1 ± 0.1 HU, respectively, which significantly reduced the noise of the final 3D printing product (p<0.001). We found that the percentage of infill according to the optimal strength was found to be 60%. Finally, development of assist devices for CT biopsy will be able to minimize artifacts and provide convenience to medical staff and patients.

The purpose of this study is to investigate the influence of the suitability of the chronic regulatory focus and the advertising message type on the evaluation of the beauty product. In addition, feeling right while and individual is reading an advertisement is measured to check the mechanism making the regulatory fit effect. The experimental design was designed with the mixed design of 2(chronic regulatory focus: promotion / prevention, between group) ${\times}$ 2(advertising message type: promotion /prevention, within a group). 100 female university student subjects in their twenties in Seoul and in the metropolitan area were asked to respond to questionnaires in the study. The reliability analysis, T-test, analysis of variance(ANOVA), and analysis of covariance (ANCOVA) on the collected data were done with SPSS WIN 12.0. The results of the study are as follows. First, the regulatory fit effect that when the individual chronic regulatory fit corresponds to the advertising message focus each other in the advertising of a new beauty product, the evaluation on the product is more positive could be checked. The promotion focus message of shampoo, the promotion focus group showed more positive response than the prevention focus group and as for the prevention focus message, the prevention focus group showed more positive results than the promotion focus group so that the effect of regulatory fit appeared. Second, when the regulatory fit effect appeared in the evaluation on the new beauty product, the fit effect on the individual chronic regulatory focus and on the advertising message focus also appeared in the measurement of feeling right. Hence, feeling right could be checked by using the mechanism of the regulatory fit effect.

제품 디자인개발 과정에서 사용성과 포용성을 확보하는 것은 매우 중요하다. 이를 위한 제품의 사용성과 포용성 평가방법으로 케임브리지 대학 엔지니어링 디자인 센터의 교수인 Simon Keates와 P. John Clarkson에 의해 Exclusion Calculation이 개발된 바 있다. 그러나 실제 제품의 평가에서 Exclusion Calculation의 효용성에 대한 연구가 부족하다. 이에 본 연구는 Exclusion Calculation을 사용하여 전기다리미을 평가하는 실험을 사례 연구로 진행하여 결과의 유용성, 정확성 및 평가항목의 직관성 3가지 측면에서 장단점을 평가하여 Exclusion Calculation의 효용성을 고찰하였다. 실험 연구에서, 11명의 디자이너가 Exclusion Calculation으로 제품을 평가한 후 Exclusion Calculation중 14개 평가항목의 직관성을 평가했다. 제품 평가 결과에 따라 Exclusion Calculation 평가 결과의 유용성을 판단하고, 표준편차를 이용하여 Exclusion Calculation 평가 결과의 정확성을 분석했다. 본 연구결과 첫째, Exclusion Calculation의 평가결과는 디자이너가 제품의 물리적 특징과 관련된 사용성 문제 및 문제의 보편성을 발견하도록 도울 수 있지만, 제품 사용 논리성 측면의 문제를 발견할 수는 없다. 둘째, Exclusion Calculation 평가 척도 기준이 모호하기 때문에 평가 결과의 정확성이 낮다. 평가항목은 전체적으로 평가 판단의 난이도가 낮지만, 인지능력과 관련된 평가항목은 직관성이 약하다는 것을 알 수 있었다.

New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.

An approach to quantitative evaluation of product usability during the design and implementation phases of the product life cycle is presented. The evaluation starts by defining a set of usability characteristics, viz. physical, cognitive and affective characteristic. Each of these characteristics is assessed by a set of usability criteria, such as functionality, visual clarity, learmability, etc. The usability criterion is then evaluated by a checklist consisting of a detailed questionnaire. The fuzzy weighted-checklist method with linguistic variables is used for quantitative analysis. Also, the method for quantifying usability improve- ments in iterative design processes is considered. This analysis procides a quantit- ative measure, which reflects the degree of excellence of product usability during the design and development phases.

The purpose of this study was to make marketing strategies for Korean fashion companies that wish to enter into foreign markets. In-depth-interviews along with documentary research were performed on consumers who lived in Italy. The interviews were executed from May to December 2010. The results of research were as follows. The general image of Korea was at a high level. Therefore, the general and economical image of Korea had a significant impact on product evaluation. However, the Italian consumer had only a little understanding about the Korean fashion brand and product. This was so because the Korean fashion companies did not appear in the Italian fashion market. However, they were accustomed to using products of Samsung and LG. Therefore, the economical image of Korea is necessary to facilitate the official entrance of fashion companies in the Italian market as well as the global market.
