Concerns about paid-facilities for the elderly with dementia from middle and upper class families have been discussed lately in Korea. Small-scale, home-like group homes for the elderly with dementia were developed in Sweden in the 1980, but they have not been effectively introduced in Korea where they remain a comparatively new concept. The group home, however, would provide a good alternative to Koreans who feel guilty when they have to leave their frail parents in large-scale facilities or hospitals instead of caring for them at home. The aim of this paper is, first, to define the care of the demented elderly who come from upper and middle class families in Korea and, secondly, to discuss the need for group homes to help care for them. A survey was done by questionnaire and was answered by 577 respondents who belonged to middle and upper class families living in Korea in December 2000. Methods of analysis were frequency, mean, and Chi-square. The results of this study were as follows: 1) the traditional notion that the eldest son should be burdened with the primary responsibility for a demented parent has weakened remarkably; 2) a small-scale long-term care facility was considered the most desirable living environment for the demented elderly; 3) the facilities families needed for professional hospitals for victims of dementia, senior citizen centers, large and small-scale long-term care facilities, day-care centers, and short-stay and service housing. The study also revealed that there was low awareness of the group home. The most preferred type of structure for group homes was a single-family detached house, and the most preferred management system was small-scale that could create home-like atmosphere. Additionally the respondents wanted group homes to consist of 6-8 residents with 2-4 persons per room. The results of this study strongly suggest that policy makers should encourage the development of smallscale group homes as an alternative form of housing for the elderly with dementia.

This study explores consumers' intention and attitude to a group home for the middle class elderly, which provide local communities with the small residential spaces where seniors can feel at home. Questionnaire method was performed, and 193 data were gathered in Jeonju city. The results are as follows. When respondents have a size of house (66.2-99.1 $m^2$), elderly disease or dementia, and their annuity or their spouse annuity, and when they are much old, their intentions to move into a community friendly group home for the aged is detected. The respondents and their spouse with the pension of more than 2,000,000 (KRW)/month have an intention to move to this group home. Also, they and their spouse with annuity have positive attitude to it, and these goups with the pension of more than 2,000,000 (KRW)/month have low negative attitude to it. So, house size, health condition, and annuity are variables to determine to move into it.

USN Middleware plays roles of broker between sensors and applications. It collects sensor data, decides the situation and sends the result to the applications. It is not good to decide the situation from one sensor data, because it may error data or reflect small part of all. In this paper, we propose sensor 'group' concept. Group is the primary unit to decide the situation. It consists of several sensors which were installed in the same place and had the same pre-defined condition to act. For example, all fire sensors in the room simultaneously trigger the ring when the same pre-defined temperature is recorded. Then, the all fire sensors are included to the same one sensor group. All operations of the intelligent USN middleware are based on the 'group' unit. We studied the intelligent rules of USN middleware based on the group.

In this experiment we emphasized the cooperative small group learning and the members of my group worked together to succeed and communicate their mathematics ideas freely. The researcher(teacher) became an observer and facilitator of small group interaction, paying attention to the ongoing learning process, Sometimes the researcher suggested some investigation approach(or discovery)being written by computer software or papers. In this experiment we provided 6 activities as follows : (1) changing the conditions in given problem. (2) operating the meaningful heuristics with the problem sets. (3) creating the problem situations related to understanding (4) creating the Modeling situations. (5) creating the problem related to combinatorial thinking in real world. (6) posing some real problem from real world. we could observed several conjectures First, Attitude and chility to interpret the problem setting is highly important to pose the problem effectively. Second, Generating the understanding can be a great tool to pose the problem effectively. Third, Sometimes inquiry approach represented by software or programmed book could be some motivation to enhance the posing activities. Forth, The various posing activities relate to one concept could give the students some opportunity to be adaptable and flexible in the their approach to unfamiliar problem sets.

The purpose of this research was to investigate the prevalence of peer harassment in preschool children and assess its influence on self-concept, hyperactivity, and behavioral problems. The participants were 4 and 5 year old children recruited from preschools and day care centers. Results indicated that a small group of children were identified as victims by self and teacher-reports. Negative self-concept and hyperactivity predicted self-reported victimization. In addition, hyperactivity, internalizing, and externalizing problems were significant contributors in teacher reported victimization.

Recent social and medical developments have significantly changed both the concept of death and the criteria for its pronouncement. Instead of considering. the heart as central to the determination for death, it is now prevalent to use death of the brain as adequate for death regardless of cardiac function in most western countries. But the brain death theory is not yet legally accepted despite growing public interest in our country due mainly to customary and moral reasons. Subsequently heart transplantation, which necessitates the concept of brain death, still remains a possible surgical entity in the future. As a part of endeavor the evaluate social atmosphere for the legal acceptance of the concept of brain death and the availability of potential heart donors, a four-page questionnaire on brain death and cardiac transplantation was given to the sophomore students of a medical college in Seoul[n=116, group I] and their family members[n=83, group II ]. The groups were chosen under the assumptions that they lacked sophisticated medical knowledge but had general medical interest so reliable data could be obtained. The majority of respondents in both group I and II thought that they knew the concept of brain death[group I 99.1%, group II 93.3%] and the definition of heart transplantation[group I 94%, group II 67.6%] at least to some extent, but only a small proportion of them was proven to have correct knowledge: brain death[74.4%, group II 39. 8%], heart transplantation[group I 31.9%, group II 30.1%]. Most respondents answered in the affirmative for the legal approval of brain death[group I 87.8%, group Il 97.9%]. The possibility of medical usage of brain dead organs was the biggest reason for brain death[group I 52.9%, group Il 47.9%]. Ninety-one percent of group I and 89.1 percent of group II responded that they were willing to give permission for donating the heart of brain-dead family members. Fifty-nine percent of group I and 51.9 percent of group II wanted their own heart donated. These results suggest, despite some inherent sampling limitations, that favorable responses to brain death and heart transplantation can be obtained among the general public if they are properly informed.

In order to meet stringent future emission regulations, especially to reduce Particulate Matter (PM) and NOX, stoichiometric diesel combustion technology with a piezo group-hole nozzle injector is being researched for reduction harmful emissions. A new nozzle layout, namely a group-hole nozzle, which has one group of small orifices with a wide spray included angle was investigated to improve the efficiency of stoichiometric diesel combustion. From this point of view, the group-hole nozzle suggested by Dense Co. is an attractive candidate method applicable to stoichiometric diesel combustion. The group-hole nozzle concept is to reduce the injector nozzle hole diameters without sacrificing spray penetration by closely locating two holes. Experimental studies have proven that the spray from group-hole nozzles have similar spray penetration to that of a single hole with equivalent overall nozzle hole area, but the spray drop sizes (SMD) are reduced, aiding vaporization and mixing.

In this study, we compared discourse by environments for using tools in terms of participation types, discourse types, and knowledge building processes. 24 first-year high school students were divided into six groups. They were assigned to the sharing tools environment, which used one marker and one smart device, or the individual tools environment, which used markers and smart devices individually. Students participated in small group learning using AR application based on the concept of chemical bonding. All classes were video- and audio-taped. Semi-structured interviews were conducted with six students who voluntarily agreed. The results of the study revealed that the sharing tools environment had a high proportion of one-student dominating type, while the individual tools environment had a high proportion of partly participating type and most students participating type. In the individual tools environment, the ratio of knowledge sharing and knowledge construction discourse was similar compared to the tool sharing environment, and the sub-discourse types were also diverse. In the sharing tools environment, only some students had a meaningful knowledge building process. On the other hand, in the individual tools environment, most of the group members constructed knowledge about the target concept, and had a meaningful knowledge building process. In addition, the misconceptions that appeared to some group members were corrected through small group discussions.

Small group learning is an educational approach to allow students to solve the problems and to achieve a common goal. Especially, small group learning in science education is one of the most important educational approaches and effective to ensure understanding of a topic. Small group learning consisting of three students in science education maximize student understanding and learning efficiency. However, It is reported that the effects of small group learning on achievement show different results, corresponding to different grouping methods(homogeneous/heterogeneous). This study investigated the effects of grouping method on difference of ecological niche of photosynthesis concepts. To achieve this, 1107 7th students were composed of homogeneous and heterogeneous groups classified into top, middle, and bottom levels. The photosynthesis units were divided into four categories: the photosynthesizing place, the substances of photosynthesis, required materials for the photosynthesizing, and environmental factors affecting photosynthesis. A questionnaire was composed by selecting concepts having a frequency of 4% or more based on prior studies on the change of the ecological status of photosynthesis. The questionnaire was scored in terms of relativity and understanding on each of the proposed concepts in the four categories. The result of this study is as set forth below. 1) There was an enhancement of learning the concept of science in small group classes consisting of 3 students. 2) To enhance the average upon composing of a group, it is proposed that the group should be formed homogeneously, and to reduce the deviation between the members, it is proposed that the group should be formed heterogeneously. Through this study, it is expected that specific studies verifying the difference or effect on the duplicity of results are conducted based on the composition of groups.
