This articles aims to analyze HOSEONGKONGSINLOK awarded to Kim Yang-bo, a eunuch, having major roles to take refuge the king Seon-jo when the Japanese invader rushed into Seoul in the time of Hideyoshi's Invasion of Korea in 1592. At that time, all meritorious retainer was to be rewarded equally by a given rules of the stipends and the gifts. But for the eunuch, differently from others, the portrait was not made to be handed down as a model. Instead one more clothes was given. This suggests that there were some differenciation of the class and the job in the evaluation of the merits. From this we can see that there might be some problems in the selection of the meritorious retainer, resulting in unfair awarding, and needing to be reevaluation from the historian. Even though somewhat worn out, this material has very important value as a historical source in terms of following viewpoint: 1) it contains all the name of the meritorious retainers at that time. 2) it suggests the social situation and affairs at that time more precisely. 3) it reveals the facts even some facts in the authentic records can be corrected.

Until now, the carriage's design has been performed by built-carriage engineers in urban railway company without the notion of railway design. Furthermore, there is no prominent change the shape of exterior and interior design between the 1970's trains and the latest one. In terms of the notion of interior space, there are a lot of differences between Oriental and Western, also region of each countries. Especially, Among Orientals, Korean is not good at utilizing the small space and react effectively as compared to Japanese. Therefore, the interior space of public transportation needs to be relatively developed to highly reasonable level in Korea. The purpose of this paper is to apply vernacular design elements for developing interior design in Korean lightrail, which is the next generation public transportation. In order to develope ideal interior design, the interior layout in carriage considers the emotional aspect as well as functional one. Also, the research of vernacular design in urban train can provide national character and traditional design and can make a success in a practical use and a visual effect. This study focused on the application of vernacular design elements for developing the design-processed model will be proposed the outline of interior layout and the shape of interior trims in the public transportation in Korea.

The single sourcing policy, in which an automobile manufacturer purchases identical or similar parts from one supplier, has an advantage of scale economy. Meanwhile, multiple sourcing policy, which allows procuring similar parts from multiple suppliers, has benefits of dispersing risks and promoting competition among suppliers. This paper analyzes the procurement policies by presenting a model of the Japanese automobile parts trade. It concludes that maturity of technology involved should be taken into account besides above-mentioned factors which have traditionally been recognized. For parts produced using evolving technologies, the single sourcing enhances purchaser’s benefits because of the scale economy in learning process. In the meantime, multiple sourcing is more beneficial to the purchaser if the parts are based on mature technologies. In either policy, if the technology involved is evolving, motivating suppliers by returning a great part of cost reduction as a reward to them may eventually increase profit for the purchaser. The conclusion supports the situation where the number of suppliers is being cut down as the trend of modularization and system deliveries of parts progresses in the auto parts industry, and suggests that returning part of benefits to parts suppliers may be encouraged from the viewpoint of auto manufacturers’ own interest.

This paper summarizes an experimental and analytical study on the seismic behavior of high strength reinforced concrete columns under cyclic loading. In total six cantilever columns with different sizes and concrete compressive strengths were tested. Three columns, small size, had a $325{\times}325$ mm cross section and the three other columns, medium size, were $520{\times}520$ mm. Concrete compressive strength was 80, 130 and 180 MPa. All specimens were designed in accordance with the Japanese design guidelines. The tests demonstrated that, for specimens made of 180 MPa concrete compressive strength, spalling of cover concrete was very brittle followed by a significant decrease in strength. Curvature was much important for the small size than for the medium size columns. Concrete compressive strength had no effect on the curvature distribution for a drift varying between -2% and +2%. However, it had an effect on the drift corresponding to the peak moment and on the equivalent viscous damping variation. Simple equations are proposed for 1) evaluating the concrete Young's modulus for high strength concrete and for 2) evaluating the moment-drift envelope curves for the medium size columns knowing that of the small size columns. Experimental moment-drift and axial strain-drift histories were well predicted using a fiber model developed by the authors.

Purpose - The study aims to show the successful application of Six Sigma in software companies for process improvement. Research design, data and methodology - A mixed methodology has been used which include both qualitative and quantitative research. In the qualitative research methodology part, a detailed and comprehensive literature study have been carried out. The literature study consists of articles, books, web materials, discussion forms and others. In the quantitative research methodology part, interviews have been conducted. Results - Six sigma is the practical application of a theoretical statistical measurement that equates to 3.4 defects per million opportunities -a position of practically zero defects for any process or service. Initially originating in Motorola Inc. in 1985 as a response to drastic quality improvement pressures from the threat of Japanese competition, it quickly gained many followers particularly G.E., Allied Signal, Ford Motor Company etc. and more recently attentions have shifted to service environments. There are still some problems and misconceptions existed about the applicability of Six Sigma in software companies. Conclusions - The paper concludes that Six Sigma can bring large benefits for software companies too. Furthermore, software companies have already started to implement Six Sigma approach, like Ericsson, Tata Consultancy Service, etc.

만족가능성 처리기는 모델 검증 및 임베디드 프로그램 검증과 같이 소프트웨어 공학의 여러 분야에서 활용되고 있다. 만족가능성 처리기를 활용하기 위해서는 주어진 문제를 처리기의 입력인 CNF 형식으로 변환해야 한다. 그러나 이 형식은 소스코드나 소프트웨어 모델보다 표현력이 낮기 때문에 최적화된 변환이 요구된다. 본 논문에서는 "n개에서 인접된 $k{\leq}n$개 선택" 문제를 CNF형식으로 변환하는 최적화된 기법을 제시한다. 제안된 방법을 다양한 일본 퍼즐에 적용한 결과 우수한 성능이 입증되었다. 우리가 알고 있는 한, 인접성에 대한 최적화된 CNF 변환 연구는 거의 없다.

Infrared channels of newly launched Japanese geostationary satellite, MTSAT-1R are compared with well calibrated MODIS/Terra infrared measurements at 3.7, 6.7, 11, 12 ${\mu}m$ bands. There are four steps in this intercalibration method: 1) data collection, 2) spectral response function correction, 3) data collocation, and 4) calculation of mean bias and conversion coefficients. In order to minimize the navigation error of MTSAT-1R, comparisons are made over the area in which the viewing angle of MTSAT-1R is less than 50$^{\circ}$. The calibration method was tested for August 2005 and within the 40$^{\circ}N$-40$^{\circ}S$, 100$^{\circ}$E-180$^{\circ}$E domain. The differences of spectral response functions were corrected through radiative transfer model simulation. Constructing collocated data differences in viewing geometry, observation time and space were taken into account. In order to avoid the radiance variation induced by cloud presence, clear-sky targets are selected as intercalibration target. The mean biases of 11, 12, 6.7, and 3.7 ${\mu}m$ bands are about -0.16, 0.36, 1.31, and -6.69 K, suggesting that accuracies of 3.7 ${\mu}m$ is questionable while other channels are comparable to MODIS

Purpose: This study was done to evaluate effectiveness of home healthcare services (HHCS) specialized for elders who received spinal surgeries. Methods: A non-equivalent control group pre-post test quasi-experimental study was performed. HHCS was developed based on the Rice model of dynamic self-determination for self-care. For data collection, a control group (n=23) and an experimental group (n=23) were selected by matching age, BMI, pain, general characteristics and type of spine surgery. Measurement tools to evaluate uncertainty and knowledge were developed by the authors. The Numeric Rating Scale (NRS) and Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were used to evaluate pain levels. Muscular strength in the legs was measured using a digital muscle tester and tape ruler. Questionnaires were used to evaluate disability in performing ADL and psychological distress levels. Results: The experimental group showed significant decrease in uncertainty (p=.028), increased knowledge (p=.038), and partially decreased pain (p=.003-.331). Partial muscle strength increased significantly (p=.021-.644). Disability in performing ADL and psychological distress in the experimental group decreased significantly compared to control group (p=.002, p=.004). Conclusion: Results indicate HHCS is an efficient home care nursing program for these elders. Further experimental studies with larger samples are required to confirm effects of HHCS.

The purpose of this study is to provide specific size data for developing a standard dress form for Korean Females between the ages of 18 and 29. Differences in sizes between dress forms used in 18-24 year-old target brands and 25-29 year-old target brands and the human body were ascertained through direct anthropometric measurements. In the 18-24 year-old target brands. 83.0-83.8cm is suitable for the bust circumference of the dress form, while in the 25-29 year-old target brands, 85.0-86.0cm is suitable. The waist circumferences of most dress forms are similar except for the Japanese C form, and there is no difference between the two groups. For hip circumference in the 18-24 year-old target brands, about 90.0cm is suitable while the 25-29 year-old target brands use additional dress forms of 91.0-92.0cm. The center front length, neck tc waist length, and front interscye breadth is 1cm shorter and the back interscye breadth is 1cm longer than indicated by the 1997 National Anthropometric Survey data.

This is paper aims to figure out the way movies and engineering have communicated and the right direction for better communication between them. Engineering no longer should be treated as playing a key role when it comes to film making. Engineering is essential in making films look real. It means that movies gain credibility from utilizing engineering, which all other types of arts also seek after. Films can be resonated better through mutual communication with engineering. The paper takes a close look at emotional aspects to figure out what the new direction of communication between movies and engineering is. People's lives shown in films and the material world that engineering represents are mingled to attain the emotional oneness between the two. This can be easily observed in Japanese movies where robots and humans have a close relationship or recent films whose theme is emotional exchange among humans and robots. This kind of contact leads us to explore newly found humans' position that was brought about in the wake of development in engineering and existential conditions that humans need to have accordingly. Artificial intelligence and neurology sectors that the engineering field is today earnestly working on are in line with it. Therefore, this article seeks to find out the meaning and value of communication between movies and engineering when establishing the fresh mankind model based on emotions and pursuit of diversity.
