This paper presents computer graphics applying the traditional Korean house(Hanok) style interior to unit-care space of Welfare Facility and proposes the possibility as interior design and construction materials. In this paper, the proposed computer graphic-based model is a single-story building that provides convenient traffic between rooms. Computer graphic-based model is presented by Auto CAD, 3D program (Sketch-UP v.8), rendering program (Podium v.2) based on the traditional Korean house and related work of unit-care welfare facility. Computer graphic-based model that combined unit-care and the traditional Korean house has the following characteristics. In each room of living space, wallpaper and flooring Korean paper(Hnaji) is considered and windows, door, furniture of traditional pattern were placed. The living room(Daechung) that is representative of the traditional Korean house and the corridor (toenmaru) are the elements to save the image of the traditional Korean house as much as possible. Especially, the corridor (toenmaru) is placed to conveniently use in nursing-care facility and home-care support facility. A public space is placed around the inside court (An-madang), while the living space (unit-care) has a sense of independence by separation. Bathroom and kitchen have a modern design for functionality than aesthetic elements.

Purpose : This study is to confirm the relation of the value orientation of the nursing unit manager and the job satisfaction and organizational commitment of the nursing unit nurse. Method : We used the systematic questionnaires as a study tool. The contents were composed of 46 questions in total such as 4 questions of general feature, 23 value-oriented questions, 10 job satisfaction questions, and 9 organizational commitment questions. The period of data collection was from August to September 2000. Result : 1) The value of flexibility was 3.82 points (${\pm}.3788$), which is above average. The values of equalitarianism was 3.37 points (${\pm}.4422$), which is above average. 2) The leadership pattern according to the value orientation perceived by the head nurses in 6 clusters has been divided into 3 patterns of change-oriented leader, task-oriented and stability-oriented leader. 3) The nurses who worked with the change-oriented leader showed higher values of job satisfaction (F=5.941, p=O.003), and affective commitment (F=5.793, p=O.003) than those who worked with the stability-oriented leader. Conclusion : As revealed in this study, we think that we have to consider that the change-oriented leader can produce higher performance of an organization than the stability-oriented leader, and write the basic data for the educational courses of leadership development or workshops etc. in order for the nursing unit managers to play their roles for the effective ward-unit management.

In today's uncertain economic environment, economic risk is inherent in making large investments on manufacturing facilities. It is, therefore, practically meaningful to divide investment over multiple periods, reducing the risk of investment. Then, the cash-flow over the entire planning horizon would comprise positive inflow and negative outflow. In this case, in general, evaluation by internal rate of return (IRR) is not feasible, because multiple IRRs are involved. This paper deals with a problem of evaluating profitability, as well as risk, of investment alternatives made in multiple times of investment over the entire horizon. Typically, an additional investment is required after the initial one, for expanding manufacturing capacity or other reasons. The paper pays attention to a unit cash-flow over two periods, decomposing the total cash-flow into a series of unit cash-flow patterns. It is easy to evaluate profitability of a unit cash-flow by using IRR. The total cash-flow can be decomposed into the series of two types of unit cash-flows: an investment type one (negative-positive) and the borrowing type one (positive-negative). This paper, therefore, proposes a method in which only the borrowing type unit cash-flow is eliminated in the series by converting total cash-flow using capital interest rate. Then, a unique IRR can be obtained and the profitability is evaluated. Thus, the paper extends the method of IRR so that it may help decision making in complicated cash-flow pattern observed in practice.

This study started with the aim of creating a parenting environment for raising children as a solution to the problem of low fertility. Communal housing is a type of housing where professional childcare environment and lives of family with children can be achieved in community space. It is an environment that supports the development of the child and life of family. However, there is no guidance system for planning such an environment. Therefore, this study aims to develop a pattern language for communal housing of families with children. The research method comes in two steps. First, the documents that provided pattern language and design guidelines about the environment of child and families with children were analyzed. Second, experts specialized in child education, women and family, environmental design were interviewed. As a result of analysis of characteristics of derived pattern language, convenience, safe feeling, comfortability in residential unit, movement, safe feeling, convenience in intermediate space convenience, safe feeling, control in community space were high. The pattern language of this study grafted the items that have proven to be important over a long period of time and the environmental design concepts for families with children in the community space. So it enabled differentiation from existing pattern language or design guidelines.

In this paper, a machine vision system for recognizing and classifying the patterns and marks engraved by die molding or laser marking on the glass panels of computer monitors is suggested and evaluated experimentally. The vision system is equipped with a neural network and an NGC pattern classifier including searching process based on normalized grayscale correlation and adaptive binarization. This system is found to be applicable even to the cases in which the segmentation of the pattern area from the background using ordinary blob coloring technique is quite difficult. The inspection process is accomplished by the use of the NGC hypothesis and ANN verification. The proposed pattern recognition system is composed of three parts: NGC matching process and the preprocessing unit for acquiring the best quality of binary image data, a neural network-based recognition algorithm, and the learning algorithm for the neural network. Another contribution of this paper is the method of generating the training patterns from only a few typical product samples in place of real images of all types of good products.

In this paper, the low cost SOA Dimming Driver which consisted of LabVIEW programming part capable of current pattern design, DAQ module for analog voltage output, and voltage to current converter has realized. The output current(possible to 3A) from the Driver was clearly constant without ripple and also showed no variance until 1mA unit for a long time operation. The proposed low cost Driver can replace the previous high cost SOA Drivers for wavelength swept lasers fully and provide the convenience and safety of auto-supplying a designed current pattern.

This study was carried out to investigate the effect of different soil moisture contents on the growth and chemical constituents of burley tobacco and on the protein pattern in tobacco leaf. Height, stem diameter, and largest leaf length of tobacco droughted from 45 to 60 days after transplanting was not recovered by rewatered amount of water supply from 60 to 75 days after transplanting, but leaf width enlarged. Dry weight per unit leaf area and total nitrogen content showed high values in low soil moisture, but total alkaloid contents were not different according to soil moisture contents. Soil moisture content didn't effect on the protein pattern of middle and upper leaves, but lower leaves showed the mild color and fewer numbers of the protein bands than those of midd1e and upper leaves.

본 논문에서는 H.264/AVC 베이스라인 프로파일을 위한 엔트로피 코딩 유닛을 제안한다. 엔트로피 코딩에서는 매크로블록 부호화를 위해 코드 테이블들을 사용한다. 이 코드 테이블에 있는 코드워드들 간에는 일정한 패턴이 존재하는데, 본 논문에서는 코드워드의 패턴을 분석하여 하드웨어 비용을 줄였다. 제안하는 엔트로피 코딩 유닛은 Exp-Golomb 유닛과 CAVLC 유닛으로 구성된다. Exp-Golomb 유닛은 하나의 유닛에서 5가지 코드타입을 처리하고, 코드 패턴을 이용하여 두 개의 덧셈기만으로 복잡한 Exp-Golomb 연산을 처리 할 수 있다. 기존의 CAVLC 유닛은 큰 사이즈의 코드 테이블을 필요로 한다. 본 논문에서는 테이블에 차분 코드워드들을 저장하여 기존 방식대비 테이블 크기를 40% 이하로 줄인다. 엔트로피 코딩 유닛은 생성된 코드워드들이 MSB에 코드값 0이 분포되는 패턴을 이용하여 쉬프터 사이즈를 대폭 줄였다.

본 논문은 상하 회전형 차동 구동부를 이용한 자기 유도 무인운반차에 대한 연구이다. 기존의 자기 유도 무인운반차는 주행 정보를 얻기 위해 자기 위치측정 센서 외에 랜드마크 및 이를 인식하기 위한 추가적인 센서가 필요하다. 또한, 일반적으로 사용되는 고정형 차동 구동부를 사용할 경우 자기 유도 무인운반차의 무게 불균형으로 인해 위치측정 오차의 증가 및 제어에 어려움이 존재하므로 2개 이상의 구동부를 필요로 한다. 이러한 단점들을 해결하기 위해 본 논문에서는 상하 회전형 차동 구동부를 이용한 자기 유도 무인운반차를 제안한다. 제안된 무인운반차는 주행 경로상에 자석의 양극으로 패턴을 구성하고 자기 위치측정 센서로 주행 정보를 획득하며, 하나의 상하 회전형 차동 구동부를 이용하여 후진 주행을 제어한다. 또한, 위치측정 오차의 감소를 위해 KF(Kalman filter)를 적용하여 무인운반차의 위치측정 정밀도를 향상시킨다. 제안된 방법의 성능을 확인하기 위하여 직접 제작한 자기 유도 무인운반차를 이용하여 실험하였다. 실험 결과, 제안된 방법의 패턴 인식 및 무인운반차의 후진 주행 성능을 확인할 수 있었으며, 기존의 방법보다 위치측정 정밀도의 RMSE가 더 감소된 것을 확인하였다.
