By decreasing in CPU price and development of computer assembling technology, personal computer fake a good chance to accelerate its supply. Recently, as being introduced new computing technology so called multi media, teaming assist system which is based on single media such as studying book, cassette tape, video tape, or something else is rapidly being replaced by new assist education system based on multi media in which it is operated by the personal computer. In the computer assist education system, there is an evaluation module which appraise learner's study level into the next study strategy. At the view of this point, this part is very important. In this part, there are some factors like Importance, complexity, or difficulty which commonly include fuzzy factors in our surrounding. But until now, we are still out of the level to handle the evaluation module adequately among the some studies. In this study, we would like to suggest a new module that evaluate learning achievement of ICAI which have a variety of fuzzy environment. We combine Independent fuzzy environment like importance, complexity, difficulty into making total evaluation of learner's achievement. By the result, with expressing by linguistic form, this study can provide the theoretical basis in which we will be able to carry out sentence toward evaluation among elementary school.

This study aims to enhance the usability of eBook reader programs on personal computers through heuristic evaluation in order to learn users' perceptions and derive key elements for interface design. For this purpose, the traditional usability evaluation and heuristic evaluation method were studied. A total of 22 evaluators of the heuristic evaluation were taken by purposive sampling to test the interface of eBook reader on PCs. This study suggested ten heuristics that focus on improving and specializing the usability aspects of reading digital materials.

Most of established study about consumer behavior was directly connected abstract value with concrete purchase behavior, nevertheless several recognizable process is intervened between abstract concept and concept behavior. Of course researchers suggest hierarchical causality through means-end chain model. However empirical study is insufficient. And it's not certain whether the consumer's personal value affects actual evaluation about product attributes. Thus the purpose of this paper was to explore hierarchical causality of personal value, benefits sought and clothing product attributes and to suggest an alternative approach method. For the empircial study the data sets were collected through 150 female consumers living in Pusan and SAS and LISREL VIII were used for statistical analysis. As the result, hierarchical causality suggested by means-end chain model was positively substantiated. That is, benefits sought is differentiated according to personal value, and actual product attributes are indirectly influenced by personal value through benefits sought. Benefits sought are found to be key mediating variables.

The purpose of this study is to identify potentially hazardous factors which can contribute to the outbreak of food borne disease and present more practical management methods in terms of sanitary management of cooking equipment and personal hygiene. 230 Korean-style restaurants in Seoul were surveyed in the same manner on the published study-A study for the Improvement of Sanitary Condition in Korean style-restaurant in Seoul city area (I). Sanitary check-lists were developed to evaluate the sanitary status of cooking equipment and personal hygiene of employee. The sanitary condition of cooking equipment the maintenance of refrigeration, food habits and personal hygiene were assessed by the sanitary score. The sanitary condition of cooking equipment, the maintenance of refrigeration as well as food habits and personal hygiene employee was in good condition. The effective sanitation education and training for good service workers should be practice for the improvement of sanitary management of cooking equipment and personal hygiene.

Cloud computing technologies are utilized and merged in various domains. Cloud computing technology-based personal cloud service technologies provide mobility and free access by using user centered storages and smart devices such like smart phones and table PCs. Therefore, we should overcome limits on the storage by solving the capacity problems of devices to provide security services in the personal cloud environments It can be addressable to provide the convenience of various security technologies. However, there are some security threats inherited from existing cloud environments and the possibilities of information leakage when devices are lost or stolen. Therefore, we designed a framework for providing secure cloud services by adding objects, such as user authorization, access tokens, set permissions by key generation, and key management assignments, for user management in personal cloud environments. We analyzed the stability of the proposed framework in terms of irreverent use and abuse, access to insiders, and data loss or leakage. And we evaluated the proposed framework in terms of the security with access control requirements in personal cloud environments.

This paper presents a CAE(Computer Aided Engineering)system for solving electrostatic field problems by means of a small size computer such as a personal computer. The system software operated on the personal computer is composed of a CAD(Computer aided Design), electric field analysis by using FEM(Finite Element Method)and DB(Data Base)of insulating materials. In addition, we discuss an application of the system to analyzing electric field such as parallel plate electrodes with an insulation spacer, which result suggests that the visualization of electric field distribution and tolerance for insulation strength enables us to assure a simplified evaluation of the insulating design.

One of the drawbacks of GA-based structural optimization is that the fitness evaluation of a population of hundreds of individuals requiring hundreds of structural analyses at each CA generation is computational too expensive. Therefore, a parallel genetic algorithm is developed for structural optimization on a cluster of personal computers in this paper. Based on the parallel genetic algorithm, a population at every generation is partitioned into a number of sub-populations equal to the number of slave computers. Parallelism is exploited at sub-population level by allocationg each sub-population to a slave computer. Thus, fitness of a population at each generation can be concurrently evaluated on a cluster of personal computers. For implementation of the algorithm a virtual distributed computing system in a collection of personal computers connected via a 100 Mb/s Ethernet LAN. The algorithm is applied to the minimum weight design of a steel structure. The results show that the computational time requied for serial GA-based structural optimization process is drastically reduced.

We deal with the headway which effects on the performance of the PRT(Personal Rapid Transit) system and the system safety. The headway, time between passage of one vehicle and the next, is one of the important factors to assess the line capacity, which has a cue to solve the problem of the congestion in public transportation. To decide the headway there are many important factors, especially such as the failure vehicle deceleration rate, the following simple analytical equation can be made to assess the relation between the line speed and the minimum headway. In this paper we employ a numerical analysis method using a simple analytical equations for the evaluation of the minimum headway and show simple simulation results.

특정 사람에 대해 느끼는 이미지 또는 특정 사람이 가지는 이미지를 어떻게 평가하고 나타낼 수 있을까\ulcorner 본 연구에서는 사람에 대해 가지는 이미지를 표준적인 감성 어휘 척도를 활용하여 모델이 가지는 감성이미지가 무엇인지를 비교평가 할 수 있는 방법을 제시한다. 연구 대상으로는 국내 화장품 회사의 모델을 활용하였다. 4명의 모델을 전체와 부분 모습의 두가지 형태로 제시하면서 각 인물이 가진 이미지를 평가하게 하였다. Personal 감성이미지를 평가하기 위해서 사람의 특성이나 이미지를 묘사하는 형용사 쌍 103개를 이용하였다. 모델 이미지에 대한 평가 반응은 요인분석을 통해 7개의 감성 어휘 요인으로 나누어졌다. 4명의 모델들은 이 7가지 감성 이미지 요인에 따라 상호 차별적으로 나타났다. 인물 감성이미지는 감성적 어휘로 표현됨과 동시에 각 인물이 가진 고유하고 대표적인 personal image로 나타낼 수 있는가를 보여줄 수 있었다. 본 연구에서는 개발된 감성이미지 척도는 사람의 이미지를 평가하는 대표적인 감성척도로 이용될 수 있을 뿐 아니라, 특정 제품을 나타내는 모델이 일반인들에 어떤 이미지를 전달하는지 그리고 모델의 이미지와 제품이 지향하는 이미지와 얼마나 일치하는지를 평가할 수 있었다.
