  • Each electrical apparatus radiates various infrared as the condition of surface and load current. Because heat distribution of the apparatus changes as the condition, it is able to analyze the condition of the apparatus by using the distribution. However, methods having been used to measure the heat distribution cannot compare normal condition with abnormal, and the apparatus has diagnosed by intuition. This paper deal with a program that is able to analyze changed temperature distribution. The program is to analyze temperatures on pixels in selected region of interest or position and is able momently and logically to analyze condition of the apparatus. The results are able to apply to a on-line monitoring system.

  • The purpose of the study is to analyze Hollywood actresses' makeup in formative characteristics and see the transition of the change for the usage as the fundamental materials to develop the future makeup field academy with the focus focused from 1920s to 2000s when the cosmetic industry began in earnest. The content of the study is to see the transition of the change by analyzing makeup of each era in formative aspect after seeing the transition of the makeup change in the social background by classifying by 10 years from 1920s to 2000s with related literature as the center in the theoretical background. The method of the study is to analyze makeup in formative aspect with total 180 pieces of pictures selected by two experts among their photos by selecting four actresses by each era and analyze Hollywood actresses' advertisement pictures which can be called as beauty icons at that time. Analysis frame to analyze the formativeness established new classification frame based on theories of Marian L. Davis, Marilyn Revell Delong, and Kang to analyze line, shape, texture, and decoration, and researcher's analysis frame was prepared based Munsell's color circle, tone analysis of P.C.C.S color system, and Kang's makeup color name to analyze colors. The result of the study is like below. Generally 20s and 30s highlighted line of eyebrows, 40s naturalness, 50s and 60s highlighted eye makeup, and from 70s makeup was focused on health, in 80s colorful makeup was boom, and 90s and 2000s has shown characteristics focused on texture of face.

  • MDDS는 디스크 시스템의 성능을 향상시키기 위해 하이퍼큐브의 각 노드에 디스크 블록들을 분산 저장하며, 인접한 노드에서 분산 저장하고 있는 디스크 블록을 중복 저장하고 있는 디스크 시스템이다. 본 논문에서는 디스크 서비스 시간을 분석하기 위한 선행 연구로서 소스 노드에서 생성된 디스크 서비스 요구 메시지가 디스크 서비스를 제공하는 목적 노드에 수신될 때까지의 시간인 전송 시간을 분석한다. 이러한 메시지의 전송 시간을 분석하기 위해 이 메시지가 링크를 통해 전송되지 못하고 대기할 확률인 전송 대기 확률을 분석한다. 이들 메시지의 전송 대기 확률을 분석하기 위해 메시지가 각 링크에서 전송되지 못하고 대기해야 하는 시간인 전송 대기 시간을 분석한다. 또 디스크 서비스 요구 메시지의 전송을 위해 링크가 사용되는 비를 분석하며, 메시지의 전송 대기 확률, 전송 대기 시간, 메시지 전송을 위해 링크가 사용될 비를 이용하여 디스크 서비스 요구 메시지의 전송 시간을 분석한다. Abstract Mirrored Declustering Disk System(MDDS) is the disk system to enhance the performance of disk system for hypercube. In MDDS, each node stores the disk blocks using the declustering technique. And the node also duplicates the disk blocks stored in neighboring nodes. In this paper, as the leading research for analyzing the disk service time, we analyze the transmission time of the disk service request message from the source node to the destination node. To analyze the transmission time of disk service request message, we analyze the probability of blocking the message related to the disk service request. For the analysis of the blocking probability, we analyze the blocking time at the link. We also analyze the rate at which the transmission link is used for transferring the disk service requests. And we analyze the transmission time of disk service request message by using the blocking probability, the blocking time, and the usage rate of link for transmitting the message.

  • The traditional holiday, Sol which is based on a lunar calendar, falls in January orFebruary and makes it difficult to analyze time series data accurately. To analyze whetherSol raises consumer prices or not, RegARIMA models and paired t tests are used. It isfound that Sol raises consumer prices of food products significantly, but So1's effects onconsumer prices of all items are not significant.

  • Objective: The aim of this paper is to introduce a method that can measure and analyze the judgment gaps between service providers and customers. Background: It is important to understand the good service that service providers and customers are thinking. If there is judgment gap between service providers and customers, it would cause an unsatisfactory service. The judgment gap should be thoroughly investigated for a good service design. Method: Lens model is a human decision making model that was proposed by Brunswick(1952). This study indicates whether the Lens model can be applied to analyze judgment gaps between service providers and customers. As a case study, a library lending service was selected. 5 librarians and 15 customers participated in the experiment that investigates their judgments on a good service. The obtained data were analyzed by a modified lens model. Results: Cue weighting policies of consumers and service providers were similar, except that consumers gave higher weight on tangibility than service providers. Service providers and consumers had a good knowledge on the service quality, but they could not well apply the knowledge to judge it. Conclusion: The lens model may be used to analyze judgment gaps between service providers and consumers in the other service areas. The decision cues that were used in this study can be changed, depending on the characteristics of the target service. Application: The method that is proposed in this study may help to investigate and analyze both consumers' and service providers' judgments on a variety of services.

  • The purpose of this study is to analyze the causal relationship, in the perspective of Total Quality Management, among the education quality factors, which were suggested in the previous researches. Lee et al. [16] had tried to analyze the relationship among education factors, but they did not estimate the education factor using latent variable concept, which is very reasonable and efficient to represent the constructed concepts. So this study attempts to analyze the causal relationship among education quality factors, represented as latent variables used in structural equation modeling (SEM), and compared with each other. In this study, education quality factors were measured by several measures, constructed as several latent variables, and then processed with AMOS, the most efficient statistical package in the SEM area. In order to analyze the causal relationship among the education quality factors constructed as latent variables, this study designed the structural equation model with suggested factors and established several research hypotheses. This study discovered a prominent causality among the education quality factors, such as education leadership, student scholastic performance and satisfaction of education quality, which is similar to that of previous research. This outcome is really a unique Korean syndrome manifest within our educational career orientation.

  • Gosan(孤山) Yun Seon-do is a literary artist and poet, Nogudang House(綠雨堂) is an invisible space composition a ${\Box}$-type of arrangement in Jeollanam-do. The study of related architecture together with Gosan Yun Seon-do has been studied variously early, Mostly, the study of the life of Haenam Yun clan(海南尹氏) and the life of Gosan Yun Seon-do. In this study, HaeNam Yun compares the houses under the roof of the public house centered on buildings. In this study, we compare and analyze Nogudang House and Gongjae Historic House(恭齋古宅), Yun Cheol-ha's Historic House(尹哲夏古宅) in the Haenam Yun clan's house building. Analyze the characteristics of architecture and analyze changes in space usage and components and settlement process. The purpose of this study is to clarify differences in structural features and to analyze what structural characteristics maintain structural characteristics. In the comparative analysis process, architectural characteristics are used as variables and each correlation is investigated, and shape difference is analyzed by difference analysis. In addition, the architectural characteristics are analyzed by analyzing the relational factors influencing the morphological change, focusing on the results of the analysis of differences between the comparative analysis objects.
