  • This paper was concerned with the nonlinear analysis on the overall stability of H-type honeycombed composite column with rectangular concrete-filled steel tube flanges (STHCC). The nonlinear analysis was performed using ABAQUS, a commercially available finite element (FE) program. Nonlinear buckling analysis was carried out by inducing the first buckling mode shape of the hinged column to the model as the initial imperfection with imperfection amplitude value of L/1000 and importing the simplified constitutive model of steel and nonlinear constitutive model of concrete considering hoop effect. Close agreement was shown between the experimental results of 17 concrete-filled steel tube (CFST) specimens and 4 I-beams with top flanges of rectangular concrete-filled steel tube (CFSFB) specimens conducted by former researchers and the predicted results, verifying the correctness of the method of FE analysis. Then, the FE models of 30 STHCC columns were established to investigate the influences of the concrete strength grade, the nominal slenderness ratio, the hoop coefficient and the flange width on the nonlinear stability capacity of SHTCC column. It was found that the hoop coefficient and the nominal slenderness ratio affected the nonlinear stability capacity more significantly. Based on the results of parameter analysis, a formula was proposed to predict the nonlinear stability capacity of STHCC column which laid the foundation of the application of STHCC column in practical engineering.

  • 성공적인 소프트웨어 개발은 QCD에 의해 결정되며, 그 중 Quality는 Cost와 Delivery를 결정하는 핵심요소이기도 하다. 그리고 소프트웨어의 규모와 복잡도가 증가함에 따라 quality의 조기 확보의 중요성이 점차 커지고 있다. 이러한 관점에서 개발 후 결함을 찾아내고 수정하는 것보다 결함예방을 위해 더 많은 노력을 기울여야 할 것이다. 결함 예방을 위해서는 peer review, testing과 같은 결함 식별활동과 함께 기존에 발생된 defect 에 대한 분석을 통해 발생 가능한 결함의 주업을 차단하는 활동이 필요하며, 이를 위해 기존의 품질 데이타의 조직화 및 활용이 필요하다. 소프트웨어의 품질 예방을 위한 방법으로 system safety 확보를 위해 사용되고 있는 FMEA를 활용할 수 있다. SW-FMEA(Software Fault Mode Effect Analysis)는 예측을 통해 결함을 예방하는 방법으로, 기존에는 요구사항 분석 및 설계 시 많이 활용되어 왔다 이러한 SW-FMEA는 개발 활동을 통해 측정되는 정보를 활용하여, 분석, 설계, 나아가 peer review나 testing 둥 개발 및 관리 활동에 적용하여 결함예방 (defect prevention) 의 수단으로 활용 할 수 있다. 본 논문에서는 기존에 시스템 분석, 설계에 focusing된 SW-FMEA를 변형하여 product 결합뿐 아니라, 개발과정 중 발생할 수 있는 fault를 줄일 수 있는 결함 예방 model을 제안한다.

  • 침입방지시스템 솔루션은 차세대에 각광받는 보안시스템으로 국내 외 시장에서 매우 활발한 보안 분야 시장을 형성할 것으로 전망된다. 아울러 국제 시장에 진출하고자 하는 국내 업체들은 검증된 제품임을 증명하는 품질 평가를 요구하고 있으며, 일반 사용자들도 검증된 제품을 선호하고 있다. 본 연구에서는 침입방지시스템 솔루션이 갖추어야할 보안성 품질평가 항목을 도출하여 분석을 통해서 품질평가항목을 세분화하고 침입방지시스템에 대한 보안성 품질평가 모델을 구축하였다. 도출된 품질평가 모델은 침입방지 시스템의 품질을 평가하고 향상시키는데 중요한 역할을 하게 된다.

  • Purpose: The purpose of the study was to test the effectiveness of an 8 session intervention program to prevent sexually transmitted diseases (STDs) among at-risk prostitutes. Method: An experimental research design was employed. Subjects were 59 prostitutes (29 in the control group and 30 in the experimental group) who agreed to participate in this study. An STD Prevention Framework derived from Cox's Interaction Model of Client Health Behavior guided the overall intervention and the components. The intervention had 8 sessions with STD-prevention strategies and was led by Public Health Nurses. Analysis included change scores, $x^2$-test, and t-test. Result: The results revealed significant increase in feelings and skills of condom use, peer belief on condom use, condom use practice, and satisfaction with service at public health centers (PHC) on STDs knowledge and skills in the experimental group. However, newly contracted STDs were not significant statistically between groups. Conclusion: The 8 session STDs prevention program showed a effect on emotions, skills and' behaviors of condom use even with the limitation of methodological rigors because of subject-specific conditions. In the future, a capacity-building model based on collaborating networks among community-based organizations will be needed to develop in effective STDs prevention.

  • 방재자원은 재난 발생시 투입하는 인력, 물자, 장비, 시설 자원을 의미한다. 물자, 장비 자원은 평상시 내부적으로 관리되는 자원으로 신속하고, 적합한 자원을 투입하여 재난을 최소화하여야 한다. 그렇지만 현재 방재자원 관리는 시군구의 재난관리시스템과 중앙의 재난관리시스템으로 이원화되어 있으며, 정보의 갱신이 실시간으로 되어있지 않아서 적시에 적합한 자원을 투입하기에 어려운 상태이다. 본 연구에서는 시군구에 분산된 방재차원에 대한 효과적인 관리를 통하여 가시성을 확보함으로써 적시에 적합한 자원을 투입할 수 있는 모델을 제시하고 있다. 특히 적합한 자원을 신속하게 파악할 수 있게 방재자원을 분류하고, RFID 표준에 기반한 방재자원의 ID와 메타데이터 정보를 제시하고, 이를 기반으로 실시간으로 방재 차원을 관리할 수 있는 모텔을 제시하였다.

  • Background: Cancer and non-communicable diseases are a major issue not only for the developed but also developing countries. Public health and primary care nursing offer great potential for primary and secondary prevention of these diseases through community and family-based approaches. Within Thailand there are related established educational curricula but less is known about how graduate practitioners enact ideas in practice and how these can influence policy at local levels. Aim: The aim of this inquiry was to develop family nursing practice in primary care settings in the Isaan region or Northeastern Thailand and to distill what worked well into a nursing model to guide practice. Materials and Methods: An appreciative inquiry approach involving analysis of written reports, focus group discussions and individual interviews was used to synthesize what worked well for fourteen family nurses involved in primary care delivery and to build the related model. Results: Three main strategies were seen to offer a basis for optimal care delivery, namely: enacting a participatory action approach mobilizing families' social capital; using family nursing process; and implementing action strategies within communities. These were distilled into a new conceptual model. Conclusions: The model has some features in common with related community partnership models and the World Health Organization Europe Family Health Nurse model, but highlights practical strategies for family nursing enactment. The model offers a basis not only for planning and implementing family care to help prevent cancer and other diseases but also for education of nurses and health care providers working in communities. This articulation of what works in this culture also offers possible transference to different contexts internationally, with related potential to inform health and social care policies, and international development of care models.

  • As the first step of risk management, risk identification is inevitable to understand the degree of work safety. However, the safety requirements can be divided in necessary factors and additional factors. Thus, we propose a safety requirements assessment model using Kano model derived from Herzberg's two-factor theory, classifying safety requirements into ideal elements and must-be elements. The Kano model is usually applied to evaluate customer satisfaction divided into three major requirements in the fields of product development and marketing: attractive, must-be, and one-dimensional requirements. Among them, attractive requirement and must-be requirement are matched with ideal element and must-be element for safety requirement classification, respectively. The ideal element is defined as preventive safety elements to make systems more safe and the must-be element is referred to as fatal elements to be essentially eliminated in systems. Also, coefficients of safety measurement and safety prevention are developed to classify different class of safety requirements. The positioning map is finally visualized in terms of both coefficients to compare the different features. Consequently, the proposed model enables safety managers to make a decision between safety measurement and prevention.

  • The prevalence of non-communicable disease (NCD) has been continuously increasing due to population ageing, and the change in consumption and lifestyle patterns. Cancers, cerebrovascular diseases, and hypertensive diseases have been the major causes of deaths in the Republic of Korea since 1983. Numerous studies have suggested the need for a sustained comprehensive treatment tailored for individual patients and recommend the development of a systematic program to manage NCD patients to provide such care. It's necessary to develop the Korean model of the community based NCD prevention and control, consisting strategy of community movement, education for the NCD patients, and partnership the primary care clinic with public health organization to meet the needs in community people.

  • 코로나 바이러스 감염증-19(COVID-19) 펜데믹이 선포되고, 세계 각국에서 확진자와 사망자와 증가함에 따라, 전 세계가 두려움에 휩싸여 있다. 이에 본 연구에서 건강 믿음 모형(Health Belief Model)을 이론적 기반으로 소방공무원과 해양경찰공무원의 감염예방행동의 심리적 요인을 분석하였다. 두 집단 사이의 COVID-19 감염 예방 행동의 유의한 차이는 없었지만, 일반적 특성에서 지각된 질병 감염 가능성, 지각된 심각성, 지각된 효과와 COVID-19 감염 예방 행동 사이에는 유의적인 양의 상관관계를 보였다. 지각된 장애요인과는 유의미한 차이를 보이지 않았다. 이 연구는 건강 믿음 모형으로 소방공무원과 해양경찰공부원을 대상으로 한 첫 번째 분석으로 그 의의가 있고, 신종 전염병 예방 행동의 수행을 위한 기초자료로 활용될 수 있다는 점에서 큰 의의가 있다고 볼 수 있다.
