  • 최근 사회 환경 변화에 따라 5대 강력범죄는 전체적으로 국민 생활의 불안 원인으로 지적되고 있다. 이에 대해 많은 노력을 기울이고 있으나 위험상황에 처한 사회적 약자에 대한 정확한 위치정보의 정확도가 부족하고 현재의 영상분석 기술로는 정확한 범죄자의 인상착의 확인 및 추적이 쉽지 않는 것이 사실이다. 이를 해결하기 위해 정밀위치결정 기술 및 지원서비스와 공간정보 기반 지능형 방범 서비스 기술 개발이 중요시 되고 있다. 따라서, 공간정보 기반 기술과 타 분야 기술에 대한 분석을 통해 연계 가능성이 있는 기술 및 서비스들에 대한 지속적으로 활용될 수 있는 방안을 제시하였다. 본 연구에서는 지능형 방범 기술과 타 분야 기술 및 서비스 간 연계방안을 마련하기 위해 기존 기술과 지능형 방범 기술 동향을 분석하고 연계 시 고려할 사항을 5가지 기준으로 맞추어 이를 토대로 연계가 가능한 서비스를 검토하였으며, 최종적으로 연계 가능성이 높은 타 분야 기술 3가지를 선정 후 연계방안을 도출하였다. 객관적인 평가기준을 통해 도출된 연계 방안은 연구기간 종료 후에도 활성화 및 기술 사업화를 이룰 수 있는 발판이 될 것으로 사료된다.

  • 본 연구의 목적은 두 가지이다. 첫째, 공유 모빌리티 중 사회적 갈등이 가장 첨예한 공유택시 플랫폼을 개발·실증하는데 있다. 이를 위해 기존 택시 서비스에 대한 소비자의 인식을 중요·만족도분석(IPA)를 활용해 분석하여 플랫폼 개발을 위한 함의를 도출하였다. 중요·만족도분석(IPA)을 통해 분석한 결과 유지관리영역에는 비정상적 영업활동과 안심 서비스가 중점개선영역에는 안전한 승차감과 손쉬운 승차가 도출되었다. 개선대상영역에는 이용 요금 수준과 운전자 정보제공 등 안전성이, 과잉투자영역에는 친절한 응대와 내외부 청결도가 각각 도출되었다. 본 연구의 두 번째 목적은 공유택시 서비스 플랫폼에 대해 이용자들의 부여하는 가치를 조건부가치추정법(CVM)을 활용해 추정하는데 있다. 본 연구를 통해 개발한 공유택시 플랫폼의 실증 서비스의 가치를 추정한 결과 평균 지불용의액(WTP)은 연간 가구당 3,621원으로 나타났으며, 해당 서비스를 김해시 전역으로 확산할 경우 평균 지불용의액이 2,515원/가구당/연간으로 나타났다. 실증서비스에 대한 지불의사에 비해 김해시 전역 확산 사업에 대한 지불의사는 69.5% 수준에 그쳤다. 이는 불특정 다수에 대한 서비스 확산, 공간적 확대에 따른 서비스 질 우려 등이 복합적으로 작용한 결과이다. 지속적인 실증을 통해 데이터를 구축하고, 이를 기반으로 서비스 고도화하여 확산을 위한 로드맵을 꼼꼼하게 구축할 필요가 있음을 시사하는 대목이다.

  • The concept of parish nursing began in the late 1960s in the United States when increasing numbers of churches employed registered nurses (RNs) to provide holistic, preventive health care to the members of their congregations. Parish nursing role was developed in 1983 by Lutheran chaplain Granger Westberg, and provides care to a variety of church congregation of various denominations. The parish nurse functions as health educator, counselor, group facilitator, client advocate, and liaison to community resources. Since these activities are complementary to the population-focused practice of community health' CNSs, parish nurses either have a strong public health background or work directly with both baccalaureate-prepared public health nurses and CNSs. In a Midwest community in U.S.A., the Healthy People 2000(1991) objectives are being addressed in health ministries through a coalition between public health nurses and parish nurses. Parish nursing is in the beginning state in Korea and up untill now, there has been no research was conducted on concrete role of korean parish nurses. The main purpose of this study was to identify, classify and analyze activities of parish nurses. The other important objective of this study was to establish an effective approach and direction for parish nursing and provide a database for korean parish nursing model through analysis and' classification of the content of the nursing record which included nursing activities. This study was a descriptive survey research. The parish nurses were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were working in churches where the demonstration project developed on parish nursing. The study was done on all nursing records which were documented by parish nurses in three churches from March, 1995 to February, 1996. Namsan, Taegu Jeei and Nedang presbyterian churches in Taegu and Keimyung nursing college incooperated together for the parish nursing demonstration project. The data analysis procedure was as follows: First, a record analysis tool was developed and second, the data was collected, coded and analyzed, the classification for nursing activities was developed through a literature review, from which the basic analysis tool was produced and cotent validity review was also done. The classification of the activities of parish nurses showed 7 activitity categories. 7 activity categories consisted of visitation nursing, health check-ups, health education, referring, attending staff meetings, attending inservices and seminar, volunteers coordinating. The percentage of activities were as follows: Visitation nursing(A: 51.6%, B: 55%, C: 42.6%) Health check-ups(A: 13.5%, B: 12.1%, C: 22.3%) Health education(A: 13.5%, B: 13.2%, C: 18.2%) Referring(A: 1.4%, B: 4.2%, C: 2.4%) Attending staff meeting(A: 18.8%, B: 13.0%, C: 12.2%) Attending inservices and seminar(A: 1.5%, B: 2.2%, C: 2.1%) Volunteers coordinating(A: 0.3%, B: 0.4%, C: 0.0%) To establish and develope parish nursing delivery network in Korea, parish nurses role, activities and boundaries of practice should be continuously monitored and refined every 2 years. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members. role, activities and boundaries of practice and arrangement of the working structure, continuing education, cooperation with community resources and structuring and organizing parish nursing delivery network. Also, It is needed to develope effective nursing recording system based on the need assessment research data of various congregation members.

  • In this study, we demonstrate for the first time a bio-inspired Cell-Microsystem to manipulate and detect living cells. Cultured retinal pigment epithelial cell line (ARPE-19) was directed to grow in a pre-defined Cell-Microsystem. The three-dimensional micropillars of 5 ${\mu}{\textrm}{m}$ in height and diameter of the Cell-Microsystem were fabricated. Inhibited DNA synthesis and transformed cell morphology were observed throughout the culture period. The demonstration of manipulating and detecting living cells by the surface topography is a new approach, and it will be very useful for the future design of cell-based biosensors and bioactuators.

  • This paper discusses the application of Bayesian techniques with test data on similar products for performing the Economical Reliability Test of new one-shot device. Using the test data on similar products, reliability test required lower sample size currently being spent in order to demonstrate a target reliability with a specified confidence level. Furthermore, lower sample size reduces cost, time and various resources on reliability test. In this paper, we use similarity as calculating weight of similar products and analyze similarity between new and similar product for comparison of the essential function.

  • This study used secondary data of the Illinois Subsidized Guardianship Waiver Demonstration, Chicago Public Schools and administrative data of the Illinois Department of Child and Family Services. Multiple regression analysis was the main statistical method. Results revealed a positive effect of foster parents' expectations on educational achievement of foster children without disabilities. Among types of educational involvement, 'direct educational activities' showed a positive effect on math and 'supervision reported by children' showed a positive effect on reading achievement. Among indices of the quality of relationship: the presence of kinship ties, permanence achievement, and level of affection between foster parents and children, only level of affection had a significant positive association with both math and reading achievement.

  • Hot spot behaviors on the disk-pad contact surface during a braking operation have been analyzed for a ventilated disk brake using the finite element method. Hot spots which were studied using a coupled thermal-mechanical analysis technique are influenced by all of the mechanical, thermal, elastic and plastic processes that are involved in braking cycles, but their temperature gradients are most affected by rubbing speeds, braking forces, and design parameters between the disk and the pad. Undesirable hot spots that are generated by local thermoelastic instabilities are intended to be removed by optimized design parameters and material properties. In this study, a three-dimensional numerical method for the demonstration of hot spot behaviors has been applied to the rubbing surfaces between the disk and the pad.

  • Although salt is known to influence the performance of nitrification significantly, it has not been well reported on how salt affects ammonia-oxidizing bacterial(AOB) community compositions and dynamics in wastewater treatment bioreactors. In this study, these questions were evaluated in a full-scale bioreactor treating saline wastewater. Clone library analysis for the ammonia monooxygenase subunit A gene revealed that AOB belonging to the Nitrosomonas europaea and the N. oligotropha lineages inhabited in the bioreactor. Terminal restriction fragment length polymorphism analysis for monthly samples demonstrated a fluctuation pattern among AOB populations, although AOB within the N. europaea lineage were dominant during the test period. Correlation analysis between patterns of terminal restriction fragments and environmental variables suggested that sodium, chloride, and sulfate were less important; rather, temperature was the most significant factor affecting the AOB community in the bioreactor.
