Smart TV is a television set with internet capabilities, computing ability, and broadcasting service that increases user interactions. Usability has been regarded as one of the most important criteria for measuring and evaluating smart TV. To evaluate smart TV from the perspective of usability, we first need to develop a measurement model by determining the major factors affecting usability, which become a measurement the evaluation criteria of the model. The objective of this paper is to suggest an AHP(Analytic Hierarchy Process) model for measuring usability of smart TV. Factors affecting usability are described from the prior research. We show how the judgment data is acquired and the usability score is computed by an numerical example.

본 연구는 연변 지역 조선족 여자 대학생을 대상으로 의복태도에 따른 의복구매동기를 조사함으로써 소비자의 심리적 특성을 밝히는데 그 목적이 있다. 2002년 5월에서 6월 사이에 300부의 설문지가 중국 연변 지역의 여자 대학생에게 배부되어 248부의 설문지가 최종적으로 분석에 사용되었다. 설문지는 5점 척도를 사용하였고, 통계처리는 SAS PC 프로그램을 이용하여 빈도, 요인분석, t-test를 하였다. 연구 결과를 요약하면 다음과 같다. 여자 대학생의 의복태도는 유행성, 유명상표지향성, 심미성, 정숙성의 네 요인으로 분류되었다. 각 요인 별로 요인의 평균값이 높은 집단과 낮은 집단으로 분류하여 의복태도에 따른 의복구매동기를 조사한 결과, 유행성${\cdot}$유명상표지향성${\cdot}$심미성${\cdot}$정숙성 네 요인 모두 각 요인 별로 평균값이 높은 집단과 낮은 두 집단 간에 유의한 차이를 나타내었다. 유행성요인에 높은 평균점수를 갖는 집단은 낮은 집단에 비해 멋진 외모나 새로운 유행을 추구하기 위해 의복을 구입하는 동기가 높았고, 미적요인에 높은 평균점수를 갖는 집단은 낮은 집단에 비해 실용적 이유보다는 사회적 모임이나 기분의 변화를 위하여 의복의 구매동기를 가졌다. 이러한 결과를 통하여 의복태도는 중국조선족소비자의 경우에도 의복구매행동을 예측하는 좋은 변수가 될 수 있으며 시장세분화를 위한 유용한 기준이 될 수 있음을 확인하였다.

Curricula relevant to labor market needs are often designed with the goals of individual employment and regional development at the forefront. This study provided information on regional scope by investigating the extent and determinants of the geographic mobility of vocational high school graduates and the effects of that mobility on first-job wage rates. Geographic mobility was defined as being employed in other provinces in which vocational schools were located. About 38% of graduates were employed in other provinces. Geographic mobility was positively related to gender and human capital such as health, course of study, vocational certificate, and job training. Mobility led to higher wage rates even after controlling for sample selection bias. The implication is that vocational high school curricula which focus excessively on provincial concerns may weaken a workforce's effectiveness.

To strengthen the competitiveness of the game industry, one needs to develope a tool for evaluation of the satisfaction level of the game users, which leads to the improvement of the quality of games and increment of the amount of game trade. In this study, we developed factors to measure the satisfaction level and estimate their distributional properties. For the purpose, using a survey data for RPG games, we discussed several aspects for normalization of score distribution for satisfaction factors and estimated their density function by use of parametric density estimation of SAS/INSIGHT. We believe that the proposed results help us to predict or estimate the satisfaction level of newly developed games as well as the current popular games.

An oriental medicinal database was used from medicinal plants for screening of anticancer agents. The prescription frequency and dosage of medicinal plats in 170 anticancer prescriptions were analyzed. From the total prescription score of each medical plant, it was found that high-scored medicinal plants have been widely studied in the previous research on the cancer treatment. Consequently, dangui, hwangui, banha, bachul, jinpy, insam, bacjakyak, deahwang, chungoong, jimo, chunnamsung, omija, hyunggae, huekchook, banggi, boclyung, osooyou were selected as raw materials for the screening of anticancer agents.

In this study, risk categorized five safety management elements(equipment and structure, evacuation, lifesaving and fire extinguishing, performance based fire safety plan, operations management) were classified in order to establish safety system of underground space. Using classified safety management elements, assessment of fire hazard was performed. After calculating the grade of evaluation categories, assessment of fire hazard was suggested. The three grades of evaluation categories are classified as to importance and four criteria of evaluation are classified as to check result based on subdivisions.

A huge amount of web documents, which are published on the Internet, provide to users not only helpful information but also harmful information such as pornography. In this paper we propose a method to detect the harmful web documents effectively. We first analyze harmful web documents, and extract factors to determine whether a given web document is harmful. Detail criteria are also described to assign a harmfulness score to each factor. Then the harmfulness score of a web document is computed by adding the harmfulness scores of all factors. If the harmfulness score of a web document is greater than a given threshold, the web document is detected as harmful. It is expected that this study could contribute to the protection of users from harmful web documents on the Internet.

We investigate the type of self-selection arising in college transfer in Korea, and then estimate the returns to additional college education gained through transfers from junior colleges to four-year colleges or universities. In this paper, we show that academic transfer is consistent with a positive selection hypothesis, in a sense that students with characteristics correlated positively to productivity are more likely to transfer to four-year colleges from junior colleges. These empirical results also meet an underlying dispersion condition. In addition, we find that the transferred would make a statistically significant return to additional college education.

Since the preexisting evaluation methods of landslide susceptibility take somehow long time to determine the slope stability based on the field survey and laboratory analysis, there are several problems to acquire immediate evaluation results in the field. In order to overcome the previously mentioned problems and incorrect evaluation results induced by some subjective evaluation criteria and methods, this study tried to develop a method of landslide susceptibility by a quantitative and objective evaluation approach based on the field survey. Therefore, this study developed an evaluation chart for landslide susceptibility on natural terrain using the AHP analysis method to predict landslide hazards on the field sites. The AHP analysis was performed by a questionnaire to several specialists who understands mechanism and influential factors of landslide. Based on the questionnaire, weighting values of criteria and alternatives to influence landslide triggering were determined by the AHP analysis. According to the scoring results of the analysed weighting values, slope angle is the most significant factor. Permeability, water contents, porosity, lithology, and elevation have the significance to the landslide susceptibility in a descending order. Based on the assigned scores of each criterion and alternatives of the criteria, an evaluation chart for landslide susceptibility was suggested. The evaluation chart makes it possible for a geologist to evaluate landslide susceptibility with a total score summed up each alternative score.

The purpose of this study is to investigate the self-directed learning readiness of university students' majored in science and engineering as life-long learners, and to analyze the relationship between self-directed learning readiness and learning style. Participants of this study are 142 students majored science and engineering in H university of Chung-nam province to participate in taking self-directed learning readiness tests and Kolb's learning style tests. The results of this study are as follows: First, the average of overall participants' self-directed learning readiness is 3.41, which is possibly regarded as 'an average' according to Guglielmino & Guglielmino (1991)'s interpretation of scores. Second, among four basic scales of participants' learning styles, the highest is found in Active Experiment (AE), the lowest is found in Abstract Conceptualization (AC). In addition, the highest thing of the four learning styles found among the participants is divergers (36.6%) and the lowest is convergers (13.4%). Finally, this study compares the high-level and low-level groups of self-directed learning readiness score with learning style. there is a statistically significant correlation between the score of self-directed learning readiness and CE, AC (p=.01). Therefore, self-directed learning readiness is related to learning style.
