The purpose of this study was to find the relation between the home management behavior pattern and contribution to the family life of urban housewives and to find out variables which influence them. The samples were selected from 522 housewives with children more than one living in Seoul. The major findings were: 1) In the housewives the degree of education of resourcefulness recognition and of communication were high home management behavior pattern was relatively morphogensis. 2) Influential variables on contribution to the family were the level of education status of employment and as the home management behavior pattern was morphogensis. 3) The relative contribution of home management behavior pattern of contribution to the family was the highest among other variables ; socio-demographic and psychological variables.

This paper suggests the algorihtm which extracts the classification parameter relative to the only feature of document patterns even though they are rotated or scaled, and also classifies them. With the complex logarithmic conformal mapping, the sample of the document pattern image makes the pattern image of the complex logarithmic plane. Because the power spectrum of this plane is invariant to the rotation, and scale of the pattern image, it is used as the characteristics parameter of the patten image. By using the coherence function, this method analyzes the standard and input power spectrum. additionally, it classifies the input pattern image. Even though input image is rotated, our algorithm can classify it without reference to the rotation, and this is possible when the scale is in the range of 0.5-1.5.

The intracellular free radicals produced at different stages of cell cycle of Saccharomyces cerevisiae ATCC 24858 were investigated by means of electron spin resonance(ESR) spectroscopy. The synchronized cells by repeated starvation and refeeding revealed different ESR spectral pattern compared to that of asynchronized cells. Each spectrum centered at g=2.005, which indicates free radicals. The relative spin concentration was maximat at the end of DNA increase. The variation of the relative spin concentration at each distinct stage of the cell cycle was evaluated in relation to ascorbate concentration, L-galactonolactone oxidase activity, and ascorbate oxidase activity. The highest activities of L-galactonolactone oxidase and ascorbate oxidase were detected just before and at the maximum of relative spin concentration, respectively. And ascorbate concentration fluctuated through each stage of cell cycle with the changes of relative spin concentration, L-galactonolactone oxidase activity, and ascorbate oxidase activity. Thus it is suggested that intracellular free radicals should be related to cell cycle, interacted with ascorbate, and may play an important role in the cell cycle of Saccharomyces cerevisiae.

The purpose of the suudy was to develop a computer program for pattern mating of women's pant's. Computerization of the pattern making process was expected to provide higher accuracy and efficiency in pattern mating. The VAX-11/750 Computer and the CALCOMP PLOTTER 965 were used in this study. The procedures of the study were as follows : 1. A slacks pattern was selected. 2. The co-ordinate points were indicated relative location of all necessary in draffing. Total sixty co-ordinate points were instituted from (AX(1), AY(1)) to (AX(24), AY(24)), from (BX(1), BY(1)) to (BX(36), BY(36)). 3. A program for drafting was developed. Refer to (Table 3). 4. The procedures of drading of standard size were accomplished by using same method. The program was developed to drafting pattern for women by putting indivisual body measurement. The body measurements for stacks pattern were as follows : slacks length. Croach length. Hip length. nip circumference. waist circumference.

The Diameter at Breast Height (DBH) provides information about the volume growth of a tree. In this study, we estimated the relative growth rates of Castanea crenata and Pinus rigida as 4.07% and 3.73%, respectively. Although the difference was low, we demonstrated that the growth rate of C. crenata is slightly faster than that of P. rigida. After calculating the relative growth rate for each section, we found that the relative growth of C. crenata decreased with time. However, the relative growth rate of P. rigida showed an overall increase. The gap widths of both species showed an increasing trend. However, the gradient of the two species was different. The gradient of C. crenata was approximately 12.0, but that of P. rigida was approximately 4.7. This means that the volume growth of C. crenata was faster than that of P. rigida during 4 years. However, this was relatively a short period for measuring the volume growth pattern, and we believe that additional useful information can be obtained by conducting long-term ecological monitoring. Results of canonical correspondence analysis showed that among the climate variables, temperature was significantly related to the gap widths for both species.

The study was to analysis the dispersion of the cooling water of Kori atomic power station using thermal infrared data. The dispersion pattern of the cooling water analysis clearly on the LANDSAT TM band 6. It was changed due to tidal current, that is, the cooling water disperses north-eastern direction during the low tide and southweatern direction during the high tide. The relative temperature distribution was mapped through the density slicing method on the images.

The purpose of this study was to develop a computer program to draft princess line onepiece dress pattern. To this study, the Turbo Pascal Compiler and the Pascal language were used. The procedures of the study were as follows: 1. A basic onepiece dress pattern was drafted by the hand operation. 2. The co-ordinate points were instituted for indication of relative position of all necessary points in drafting. Total sixty-nine co-ordinte points (front: thirty-five, back: thirt-four) were instituted. 3. The two subprograms for main program were developed to solve geometric problems and to draft straight lines and curved lines of the onepiece dress pattern. 4. The program was accomplished by putting indivisual body measurement 5. Grading fo five size was given.

The development of efficient multimodal interfaces and fusion algorithms requires knowledge of usage patterns that show how people use multiple modalities. We analyzed multimodal usage patterns for TV-guide application scenarios (or tasks). In order to collect usage patterns, we implemented a multimodal usage pattern collection system having two input modalities: speech and touch-gesture. Fifty-four subjects participated in our study. Analysis of the collected usage patterns shows a positive correlation between the task type and multimodal usage patterns. In addition, we analyzed the timing between speech-utterances and their corresponding touch-gestures that shows the touch-gesture occurring time interval relative to the duration of speech utterance. We believe that, for developing efficient multimodal fusion algorithms on an application, the multimodal usage pattern analysis for the given application, similar to our work for TV guide application, have to be done in advance.

As the demand for mechatronic systems and high performance increases in the machinery industry, the importance of improving friction characteristics is emphasized. During relative movement of objects, friction and wear occur on two surfaces in contact, and various methods are being designed to increase the lifespan and energy efficiency of machines. The energy increase effect using lubricants is a well-known method. In this study, a micro-sized rectangular grid pattern was produced by applying a precise micro-pattern photo lithography process. Rectangular grid patterns of the same shape and friction behavior according to the size of the pattern were produced in convex and concave shapes, and the tribological characteristics of each were analyzed.

본 연구의 목적은 상대적 위상을 이용한 시각적 협응 패턴의 지각이 조절변수의 변화에 따라 HKB 모델(Haken, Kelso, Bunz, 1985)의 예측에 따르는지 확인해 보는 것이었다. 또한 격자무늬 배경을 이용한 부가적인 시각 정보가 협응 패턴 분별의 정확성과 안정성을 향상시키는지 알아보았다. 피험자들은 일반 배경과 격자 배경 중 하나의 그룹에 속하여 패턴 지각 연습과 패턴 분별 시험을 하였다. 피험자들은 좌우로 이동하는 두 점 사이의 상대위상으로 정의된 $0^{\circ}$, $18^{\circ}$, $36^{\circ}$, $54^{\circ}$, $72^{\circ}$, $90^{\circ}$, $108^{\circ}$, $126^{\circ}$, $144^{\circ}$, $162^{\circ}$, $180^{\circ}$ 패턴을 관찰하였다. 패턴 지각 연습은 두 점의 진동 주기 0.25 Hz에서 시행되었고, 패턴 분별 시험은 0.5 Hz, 1 Hz, 2 Hz에서 시행되었다. 패턴 분별 시험에서 얻은 분별 점수, 절대 분별 오차, 분별 안정성 자료를 통계적으로 분석하였다. 분별의 정확성과 안정성은 진동 주기가 느릴 때는 "뒤집어진 U" 모양을 띄다가 진동 주기가 빨라짐에 따라 $180^{\circ}$ 상대위상 패턴에 가까운 패턴들에서 정확성과 안정성이 감소하였다. 이러한 발견은 협응 패턴의 지각적 분별 역학이 HKB 모델을 따름을 나타낸다. 부가적 환경 정보인 격자무늬가 협응 패턴 분별의 정확성과 안정성에 도움은 되지 못하였다.
