본 논문에서 진행한 연구는 고속의 ARM 아키텍처 기반의 ARM11 코어를 적용한 최신 MPU인 S3C6400을 이용한 플랫폼을 구현하고 구현된 플랫폼에 OS로서 리눅스를 포팅하여 Handheld 타입의 가스 센서용 플랫폼 구현에 관한 연구이다. 무선으로 데이터를 전송받기 위하여 블루투스를 이용한 네트워크 환경을 구축하였다. QT/embedded를 사용하여 리눅스 상에서 유연한 어플리케이션 개발 환경을 구축하여 관련된 프로그램을 작성하였다. This paper focuses on the implementation of hand held typeARM11 Platform for gas sensor based on Embedded Linux OS. The S3C6400, which is ARM11 architecture based, is the key component of the ARM11 Platform, Bluetooth is adapted to consist the network for the wireless transmission of environmental data between a sensor node and hand held type ARM11 Platform. Linux is ported to the Platform, QT/embedded is used for the application development.

The purpose of this study is to examine the factors of residential satisfaction and characteristics of university dormitory by an analysis of crime anxiety and questionnaire survey. The results of this study are as follows. First, the residents" satisfaction was related to lighting and ventilation, soundproofing and privacy protection. Second, it is inferred that the perceived crime anxiety by space was high in outer space, which appeared to be an environmental factor lacking the protection of external space. An analysis of the satisfaction and importance of the residential environment revealed the need for improvements in building facilities and safety factors.

In this study, based on official statistical data, the results of research that analyzed the trend and characteristics of crime and the effects of the CPTED project were comprehensively reviewed. As a result of previous studies, CPTED for crime prevention is spreading, and the effect of CPTED is continuously being investigated. As a result of statistical data analysis, overall crimes are declining, especially theft crimes. And it was confirmed that the crime anxiety perceived by the people tended to decrease.

The purpose of this study is to analyze the perceptions and behavioral characteristics of university dormitory before and after COVID-19 and explore future implications. The results of this study are as follows: First, the satisfaction level about private space(living space) increases as the dormitory was operated as a single room after COVID-19, but the change of satisfaction level about public spaces(learning space, exercise space, etc.) is small due to the closure of those spaces. Second, in terms of behavior, learning and hobby activities have increased since COVID-19 due to increased residential times in dormitory. Thirdly, in terms of criminal safety, fear of crime has decreased significantly since COVID-19. In conclusion, based on these results, it is thought that changes of university dormitory planning in the private space where possible behavior in the shared spaces of the dormitory can be made in the future.
요부 심부근 안정화운동이 뇌졸중 환자의 몸통 안정화 및 균형에 미치는 영향

본 연구는 뇌졸중 환자를 대상으로 일반적 재활운동과 요부 심부근 안정화 운동을 적용한 실험군 14명과 일반적 재활운동을 시행한 대조군 14명을 대상으로 몸통의 안정화와 균형에 미치는 영향을 알아보는데 그 목적이 있다. 실험은 8주 동안 주 5회 1일 30분씩 진행되었다. 실험 전과 후의 측정은 몸통의 안정화 능력 평가는 몸통 손상 척도(Trunk Impairment Scale; TIS)를 사용하였으며, 균형능력평가는 기능적 뻗기 검사(Functional Reach Test; FRT), 일어나 걷기 검사(Time Up and Go test; TUG)을 측정하여 수집된 자료를 분석하였다. 두 집단의 운동 전·후 차이는 실험군에서 몸통의 안정화 능력, 기능적 뻗기, 일어나 걷기에서 유의한 것으로 나타났으며(p<.05), 두 집단 간의 비교에서 몸통의 안정화 능력, 기능적 뻗기에서 유의한 것으로 나타났다(p<.05). 따라서 요부 심부근 안정화 운동은 뇌졸중환자의 균형능력 향상에 효과적이며, 이를 바탕으로 임상에서 뇌졸중 환자의 균형능력 증진에 요부심부근 안정화 운동이 더 큰 효과를 볼 수 있을 것으로 생각한다. The purpose of this study was to investigate the effects on the stabilization and balance of the trunk in 14 experimental groups who performed general rehabilitation and lumbar deep muscle stabilization exercise in stroke patients and 14 control groups who underwent general rehabilitation exercise. The experiment was conducted 30 minutes a day five times a week for eight weeks. Before and after the test, the stabilization ability of the trunk was measured using the Trunk Impairment Scale (TIS), and the balance ability was assessment by the Functional Reach Test (FRT) and the Time Up and Go test (TUG) was measured to analyze the collected data. The difference between the two groups before and after exercise was significant in the stabilization ability of the trunk, functional reach test and time up and go test in the experimental group (p<.05). Comparison between the two groups was significant in the stabilization ability and functional reach test of the trunk (p<.05). Therefore, the lumbar deep muscle stabilization exercise is effective for improving the balance ability of stroke patients. Based on this, the lumbar deep muscle stabilization exercise will be more effective in improving the balance ability of stroke patients.

In 2004, the minimum residential criteria were enacted as part of the housing welfare policy. Since then, the area standard was raised once in 2011, but it is hard to say that the housing environment has improved due to the increase in the number of households and the diversification of housing types. Thus, this study considered the lowest residential criteria prior to the study and analyzed overseas cases.
