The purpose of the study of multi-robot system is to realize multi-robot system easy for the control of robot system in case robot is adapted in the complicated environment of task structure. The purpose of the study of multi-robot system is to realize multi-robot system easy for the control of robot system in case robot is adapted in the complicated environment of task structure. To make real time control possible by making effective use of recognized information in this dynamic environment, suitable distribution of tasks should be made in consideration of function and role of each performing robots. In this paper, IHMA (Intelligent Hybrid Modular Architecture) of Intelligent combined control architecture which utilizes the merits of deliberative and reactive controllers will be suggested and its efficiency will be evaluated through the adaptation of control architecture to representative multi-robot system.

The specific purpose of this was to investigate if ir was feasible to design and execute garments that were multi-functional in purpose for women living in an expended world of social and occupational interaction which rerequired flexibility and convenience in their clothing appropriate to their multiple roles in society. The study was to carry out based on the selected situations(business situation-social situation and private situation-social situation) and designs deduced from the situations. The garments could permit flexibility in style through adjustable features which could be attached to, or detached from, the garment depending on the occasion and need of the wearer. As the results of the study, the characteristics of multi-functional garments were found as follows : First, the garments could bring about flexibility in garment formation through adjustable details, overlay and patch, in order to increase the multi-functional usage of the garments. Second, the style of garments could be expressed design images to meet the needs of flexibility and convenience for the various occassions. Third, the multi-functional garments could meet the needs for time and economic values for the women who play multple roles.

목적: 본 연구에서는 계면활성성분 및 함유량이 다른 콘택트렌즈 관리용액의 세척효율 및 가시광선투과율에 미치는 영향을 알아보고자 하였다. 방법: 다른 재질의 소프트렌즈(etafilcon A 및 hilafilcon B 재질)에 인공누액을 이용하여 각각 단백질을 침착시킨 후 계면활성성분 및 함유량이 다른 6종류의 다목적용액을 사용하여 세척한 후 그에 따른 세척효율 및 광투과율을 비교하였다. 결과: Etafilcon A 재질 렌즈의 경우 다목적용액으로 문지르기를 하여 세척하였을 때 세척효율은 다목적용액의 계면활성성분 농도와 표면장력에 따라 약 23~43%로 다양하게 나타났으며, 계면활성성분 이외에 과산화수소를 함유하는 다목적용액으로 세척 시 가장 높은 세척효율을 보였으나 렌즈에 잔존하는 단백질량이 많았다. 다목적용액으로 세척 후 가시광선투과율은 89.8%~90.8%으로 나타났다. Hilafilcon B 재질 렌즈에서는 인공누액에 7일간 배양하더라도 침착되는 단백질양이 매우 적어 etafilcon A 재질 렌즈의 5~10% 수준의 단백질량을 보였으며 가시광선투과율 감소도 크지 않았다. 다목적용액으로 문질러 세척하였을 경우 45.4~67.4%의 세척효율을 보였으나 etafilcon A 재질 렌즈와는 다른 세척효율 순서를 보였으며, 광투과율은 새 렌즈 수준으로 회복되었다. 결론: 이상의 결과로 소프트렌즈의 단백질 침전물의 올바른 관리를 위하여서는 다목적용액의 계면활성성분이나 원리에 대한 이해를 바탕으로 렌즈 재질과 침착된 단백질량에 따라 적절한 다목적용액을 선택하여야 하며, 제조사의 가이드라인과 상관없이 문지르기를 하여 관리하는 것이 보다 효율적임을 알 수 있었다.

Recently, many countries around the world began to show interest in safety against terrorism, fire, and natural disasters. This study aimed to propose a quantitative measurement system for emergency evacuation and safety for various kinds of terrorism and fire within high-rise multi-purpose facilities, which can measure the pedestrians' ordinary walking patterns in the concourse with the highest pedestrian volume out of all the spaces within multi-story buildings, predict pedestrians' evacuation walking lines when a sudden disaster breaks out, and analyze the gait coefficient, occupant density, and evacuation behavior time.

Purpose: The purpose of this study was to investigate the level of cultural competence, intercultural communicative competence, and multi-cultural job stress among healthcare workers and to explore factors that are related to their cultural competence. Methods: The study subjects were 142 healthcare workers at a general hospital. Data were collected using a questionnaire on cultural competence, intercultural communicative competence, and multi-cultural job stress. A t-test, ANOVA Pearson's correlation coefficient, and multiple regression analysis were conducted using SPSS. Results: Cultural competence was significantly related to the necessity of multi-cultural education, and intercultural communicative competence was significantly related to age, a vocational career, communication in foreign languages, and having multi-cultural neighbors. Moreover, multi-cultural job stress was significantly related to religion. In multiple regression results, cultural competence was found to be related to intercultural communicative competence and multi-cultural job stress. Conclusion: Healthcare workers who are set to care for multi-cultural patients should improve intercultural communicative competence and reduce multi-cultural job stress.

The purpose of this study was to evaluate the shearbond strength and resin-dentin interface of three different dentinal bonding systems in primary and permanent teeth. Thirty extracted human primary molars and premolars, which were non-carious and free of obvious defect, were selected for this study. All specimens were divided into six groups with two groups allocated for each of the three dentinal bonding system(All-bond 2, Scotchbond Multi-Purpose, Gluma bonding system). After completion of bonding composite to dentin using each tested dentin bonding system, bond strength measurement and histological observation were performed. The results are as follows: 1. All-bond 2 and Scotchbond Multi-Purpose, A good quality hybrid layer was identified, the morphology of which could be equated with the zone of H-E and Brown-Brenn staining. In Gluma bonding system, hybrid layer was very thin, and separated from the solid polymer. 2. All-bond 2 had the highest mean shearbond strength, followed by Scotchbond Multi-Purpose and Gluma bonding system in both primary and permanent teeth. There was no statistically significant difference between All-bond 2 and Scotchbond Multi-Purpose. Statistically significant difference could be found between Gluma bonding system and the other two groups(p<0.05). 3. The fracture patterns observed were mainly the mixture of adhesive failure and dentin dettachment pattern in All-bond 2 and Scotchbond Multi-Purpose while adhesive failure prevailed in Gluma bonding system.

Purpose: The purpose of this study was to identify the attitude toward multi-cultural families. Method: The Q-methodology which provides a method of analyzing the subjectivity of each item was used. Thirty nurses classified the 34 selected Q-statements into a normal distribution using a 9 point scale. The collected data was analyzed using the Quanl PC program. Result: Four types of attitudes toward multi-cultural families were identified. The first type(value-neutral acceptance) considered multi-cultural families as individual's choice so they accepted it as one type of families and they persisted that nobody can oppose or blame for it. The second type(inevitable acceptance) considered multi-cultural families as a necessary evil that can solve the problem of old bachelors' seeking marriage. The third type (NIMBY: Not in my backyard) understood various advantage of multi-cultural families but they opposed their own family's intermarriage. The fourth type(negative prejudice) considered intermarriage as trading for the benefit of each other and they had strong antipathy against multi-cultural families. Conclusion: The results of the study indicate that different approaches of educational program based on the four types of attitudes toward multi-cultural families are recommended.

Purpose: Simulation-based learning has become a powerful method to improve the quality of care and help students meet the challenges of increasingly complex clinical practice settings. The purpose of this study was to identify the learning effects using high-fidelity SimMan and multi-mode simulation. Methods: Participants in this study were 38 students who were enrolled in an intensive course for a major in nursing at R college. Collected data were analyzed using Chi-square, t-test, and independent t-test with the SPSS 18.0 for Windows Program. Results: There were no statistically significant differences in learning effects between high-fidelity SimMan and multi-mode simulation group. However, skills in clinical performance in the high-fidelity SimMan group were higher than in the multi-mode group (p=.014), communication in clinical performance in multi-mode simulation group was higher than in the high-fidelity SimMan group (p<.001). Conclusion: Multi-mode simulation with a standardized patient is an effective learning method in many ways compared to a high-fidelity simulator. These results suggest that multi-mode simulation be offered to students in nursing colleges which cannot afford to purchase a high-fidelity simulator, or offered as an alternative.
