양선옥,이근수 안성산업대학교 1995 論文集 Vol.27 No.-

본 논문에서는 핸드제스쳐 인식시스템의 성능향상을 위하여 상요자로부터의 학습정보를 얻기 위해 시스템의 일정 계획에 의한 훈련 자료의 획득과 획득된 자료로부터 제스쳐 인식 파라미터를 학습하는 학습시스템의 구조를 소개한다. 학습시스템은 사용자에게 임의의 동작을 지시하는 모델을 제시한 후, 카메라를 통해 사용자의 반응을 입력 받는 가이더, 입력된 영상을 분석하여 정확한 훈련 자료를 획득하는 해석모듈과 훈련 자료로부터 분할 요소를 학습하는 학습모듈로 구성된다. 시스템은 정확한 훈련 자료를 획득하기 위해서 해석모듈내에 계획유도프레임, 상황프레임, 해석프레임 등의 프레임 지식표현 방법을 이용한다. In this paper, we describe a learning system to acquire training data by system's plan and to learn parameters of hand-gesture recognition from them. The system consists of a guider, which provides some actions to user and captures his(or her) responds through camera, an interpreter module, which acquires exact training data, a learning module, which learns segment components from acquired data. It uses a method of frame knowledge representation to extract correct training data. It includes PlanDriver, Situation, and Interperter frame in the interpreter module.

마스크 상의 거친 표면을 정의하기 위해서 Monte-Carlo 방법이 적용되었다. 극자외선 마스크의 거친 표면 함수, 즉 power spectral density 에 의해 표현된 무작위적인 표면의 높이 변화는 상면에서의 전기장을 계산하기 위해서 재정의 되었다. Feynmann의 접근 방식과 유사한 산란에 대한 일반식을 유도하였고, 이는 결상과정에서 마스크의 단차상의 거친 측면에 의한 효과를 알아보기 위해서 적용되어졌다. 거친 표면과 완전히 편평한 표면에 대한 전기장의 위상과 진폭 변화 정도를 비교하기 위해서 다중 산람 문제 또한 여러 다른 패턴에 대하여 이 논문에서 다뤄졌다. The Monte-Carlo Method is adopted to define the roughness of the mask structure. A random surface height variation described by power spectral density for the rough surfaces of an estreme ultraviolet (EUV) mask is to be redefined to calculate the field in the image plane. A general explicit formula of the scattering, which is analogous to Feynman's approach, is derived, and it is adapted to the EUV mask structure to evaluate the effect of the surface roughness of the side wall of the mask topography on the image formation. The multiple random scattering problems are dealt with the different pattern types in order to compare field variations in phase and amplitude with the ideal flat surface.

There are several types of salts, which are classified into raw salt (Chunil salt, CS), purified salt (PS) and processed salts (Gueun salt, Bamboo salt) in Korea. Gueun salt (Gs) is made by baking CS in the ceramic vessel at 800℃. Bamboo salt (BS) is produced by baking CS, bamboo and mud in an oven at 1,300℃. In this study, effects of these salts on tumor formation, NK (natural killer) cell activity and lipid peroxidation in kidney and heart were investigated in the sarcoma-180 cell transplanted mice. Sarcoma-180 cells were transplanted subcutaneously into the left groin of Balb/c mice. Then, various kinds of salt, including 1 time heat treated KCI mixed BS-A (CS : KCI =3:7)and B (CS : KCI = 5:5), supplemented diet at concentrations of 10% were fed for 21 days from 24 hours following transplantation. The body weight decreased when 10% salt added diet was fed to the sarcoma-180 cell treated Balb/c mice. The body weights of CS, PS and treated groups were lower than their initial weights (19 ~ 20 g). Spleen and liver index were lower in the mice administered PS and GS than sarcoma-180 cell treated control group. KCI mixed BS-A and B reduced the content of malondialdehyde (MDA) in the kidney and heart that increased by the injection of sarcoma-180 cells. The feeding of PS in the diet increased the levels of MDA in the kidney and heart of sarcoma-180 treated mice compared to the control group. These results exhibited that KCI mined BS could suppress.

The purpose of this research is to compare and analyze the physical self-efficiency and physical education satisfaction due to existence of new sports physical education class, and school life adaptation. Also by systematically analyzing the relationship of cause factors, we will understand the primary affecting cause due to attending physical education. Moreover by effectiveness proof close examination of new sports in physical education, we wish to help in creating healthy leisure culture for teenagers to develop mentality and provide foundation for life-time physical education activities. In order to achieve this goal, this research tested one middle school which practices new sports physical education program and two middle schools which practices regular physical education. 3 classes from each school, total of 9 classes have been tested and 302 questionnaire papers were passed out. Out of these papers, 294 papers were valid after material arrangement, and have been final analyzed. With above research purpose and method as basis, hypothesis about the affect physical self-efficiency and physical education satisfaction of middle school students adjustmenting new sports has on school life adjustment has been verified. After doing so, the below results has been induced. First, physical self-efficacy had meaningful difference according to physical exercise experience. Second, physical education satisfaction had no meaningful difference according to physical exercise experience, but showed to have influential power. Third, School life adaptation had meaningful difference according to physical exercise experience. On the other hand, school surrounding adaptation had no meaningful difference according to physical exercise experience, thus it shows that it is not related. Fourth, physical self-efficacy showed to have difference according to recognized health status. Fifth, Physical self-efficacy of students participating in new sports education and general physical education did not have meaningful difference. Sixth, Physical education satisfaction of students participating in new sports education and general physical education did have partial differences. Seventh, School life adaptation of students participating in new sports education and general physical education did have partial affective power. Eighth, Physical self-efficacy did showed to have partial positive affect on the physical education satisfaction. Ninth, Physical education satisfaction did showed to have positive affect on school life adaptation. Lastly, in school regulation adaptation, when physical education guidance material satisfaction and physical education environment satisfaction has co-relationship, physical education guidance material satisfaction showed to have negative co-relationship, thus as physical education guidance material satisfaction increases the school regulation adaptation decreases. In addition, physical education environment adaptation has positive relationship, thus as physical education environment adaptation increases, school regulation adaptation increases. As shown, in school physical education non experienced new sports is having direct and indirect affect on student’s physical self-efficacy, physical education satisfaction, and school life adaptation. Moreover physical self-efficacy has partial affect on physical education, and physical education satisfaction has direct relationship has school life. Thus we found out that these three causes are co-related.

Solution copolymerization of Styrene(St.) with 2-Hydroxypropylacrylate(2-HPA) was carried out with Benzoylperoxide(BPO) as an initiator in toluene at 80℃ in a batch reactor. Reaction volume and reaction time were 0.3 liters, 7hours respectively. The time to reach steady state was about the six time. The monomer reactivity ratios, r1(St.) and r2(2HPS) were determined by both the Kelen-Tudos method and the Fineman-Ross method : r1(St.)=0.376(0.330), r2(2-HPA)=0.408(0.778). The activation energy of thermal decomposition was in range of 33∼55 kcal/mol.

We extract hand region by using color information, because it is an important feature for human vision to distinguish objects. Because pixel values in images are changed according to the luminance and lighting source, it is difficult to extract hand region exactly without previous knowledge. We generate a hand skin model at leaning stage, and extract hand region from images by using the model. We also use Kalman filter to consider the change of pixel values in hand skin model. Kalman filter restricts the search area for extracting hand region at next frame also.

This study was conducted to provide the basic informations necessary for tissue culture of job's tears(Coix lacryma-jobi L.). Embryos excised from matured seeds of job's tears were cultured in different medium(MS, Miller, B5 and N6) and different concentrations and combinations of growth regulators (2, 4-D, IAA, NAA, BA and Kinetin) and leaf tissue of young job's tears plant was cultured in different sucrose concentrations and pH. The heighest ratio of callus formation was obtained in MS medium, which was followed in the order of N6, B5 and Miller medium. Fresh weight of callus was 454mg in MS medium supplemented with 2, 4-D 3mg/1. No other growth regulators alone but 2, 4-D induced callus. Callus formation was better in supplemented medium with 2, 4-D alone than with 2, 4-D+BA combination. The callus formation was best in the medium supplemented with 2-3 mg/1 of 2, 4-D. Callus was not induced in any combination of growth regulators without 2, 4-D. As BA and kinetin concentrations were increased, callus formation was reduced regardless of 2, 4-D conentration in 2, 4-D, BA and Kinetic combinations. 2, 4-D+BA combination was better than 2, 4-D+Kinetic combination for calls formation. Callus formation was induced best when medium was supplemented with sucrose 2% and its fresh weight was 161mg. Although callus was induced in pH range of 4,5-7.0, the best result was obtained in pH 6.0 and the fresh weight was 156mg.

Purpose: This study was designed to examine increase in hamstring muscle extensibility with ballistic stretching, static stretching, hold- relax, and hold-relax-agonist techniques. Materials and methods: Subjects were designed randomly to passive stretching, static stretching, hold- relax, and hold-relax-agonist techniques. A total of 40 subjects, with limited hamstring flexibility (defined as 30° loss of knee extension measured with the tight held at 90° of hip flexion) were recruited for this study. Hamstring muscle extensibility was measured using the passive 90/90 test before and after the 3-weeks program. the range of knee extension was measured by Goniometer(made in USA). Data analysis were compared the flexibility within treatment period on each group after program by repeated measure 2- way ANOVA using SPSS for window Results: Difference were signification for test and for the test by-group interaction. 1. All stretch technique programs produced a greater decrease in knee extension range within treatment period on each group (p<0.05). 2. The hold-relax-agonist technique produced a greater decrease in knee extension range than did passive stretch, static stretch, and hald-relax (p<0.05). 3. passive stretching technique produced a lesser decrease in knee extension range than did other stretch technique programs (p<0.05)

Purpose: This descriptive study was done to identify the rate of repeated falls in hospitalized elders and characteristics related to the falls, as well as characteristics of fractures resulting from falls. Method: Using a check list designed by the researchers, data were collected from October 15 to October 25. 2007 in a hospital in Seoul by examining the medical records of all elders. 65 years or older who sustained fractures from falls and were admitted to the hospital during the period from July, 1, 2006 to June 30. 2007. Frequency, percentage, mean, and x² with the SPSS 12 were used to analyze the data. Result : Of the demographic characteristic, economic status, and of the physical characteristics, vision and hearing showed highly significant relationships to repeated falls (p<.05). But the other demographic, physical, and environmental characteristics were less significant. The rate of repeated fall for the elders was 37.5% and the rate of fractures as a result of falls was 61.9%. Conclusion : To prevent falls in elders and thus improve the quality of their lives, nurses should focus on physical and economic status of elders.
