본 연구의 목적은 N시에 소재한 공공병원의 금연클리닉 프로그램을 이용한 흡연 환자(입원 및 외래 포함)를 대상으로 Prochaska와 Diclemente의 변화단계모형(Transtheoretical Model, TTM)을 적용한 금연동기단계에 따른 코칭프로그램 참여 전과 후 대상자의 흡연량, 니코틴의존도, 호기 일산화탄소 농도, 소변 코티닌의 차이를 확인하기 위함이다. 연구설계는 금연동기에 따른 코칭프로그램이 환자들의 금연에 미치는 효과를 확인하기 위해 대상자의 흡연량, 니코틴의존도, 호기 일산화탄소 농도, 소변 코티닌을 프로그램 전, 2주, 6주 후간의 차이를 비교하는 다중반복 간헐적 시계열 설계연구이다. 본 연구에서 활용된 자료는 2011년 공공보건의료프로그램 중 금연프로그램을 통해 수집된 2차 자료를 활용하였다. 코칭프로그램은 6주동안 중재가 진행되며, 첫방문, 2주째 방문, 6주째 방문에 제공되며, 12주째 금연 유지 상태를 점검한다. 연구대상자의 교육 전과 교육 후 흡연량, 니코틴 의존도, 호기 일산화탄소 농도, 소변 코티닌 차이는 카이제곱 검정과 t-test로 비교하였다. 이 연구대상자는 총 47명이며, 남자는 44명(93.62%), 여자는 3명(6.38%)으로 대부분 남자였다. 금연동기단계별 대상자 수는 실천단계가 4명(8.51%), 준비단계는 43명(91.49%)이었다. 금연동기단계에 따른 코칭프로그램 전과 후를 비교한 결과, 실천단계 집단은 대부분 프로그램 전과 후 흡연량, 니코틴의존도, '0'상태를 유지하였다. 준비단계 집단은 흡연량, 니코틴의존도, 호기 일산화탄소가 프로그램 전과 6주후 유의한 차이를 보이면 감소한 것으로 나타났다(p<.001). 환자들을 대상으로 한 병원 현장에서의 금연코칭 프로그램은 매우 효과적임을 확인할 수 있었다. 하지만, 환자들을 대상으로 한 금연프로그램은 건강한 사람들에 비해 인적 재정적 부담이 더 높다. 따라서 환자들의 금연을 위해 적극적인 인적, 재정적 지원이 있어야 할 것이다.

Purpose. Based on the comparison and analysis with those of United States, the aim of this research is to find the problems in current management, operation and future directions of emergency medical service (EMS) fund in S. Korea and to provide basic resources and appropriate measures to make a right decision in policies for EMS fund. Methods. Data from Ministry of Health and Welfare and other various sources during 1995 to 2012 were collected and analyzed. Results. From our analyses, several problems are identified in EMS fund operation. In brief, problems discerned are as follows. First, whereas the purpose and direction of EMS fund operations in United States are highlighted and focused on pre-hospital EMS system and associated infrastructures which need to be constructed, those of S. Korea are emphasized mainly on the in-hospital EMS system so far. Second, on the contrary to the fact that the EMS funds in United States are tuned to pre-hospital EMS system to provide prompt and efficient emergency care at the emergency scene of pre-hospital stage and to achieve the development, design, planning and demonstration projects for pre-hospital EMS systems, up to date, our investment of EMS funds demonstrated an excess biased inclination toward the construction of in-hospital EMS system, which is far from the realization of constructive and vital pre-hospital infrastructures. Third, while emergency medical technician is important and principal body in the management of emergency medical funds in United States, so far, no EMS funds in S. Korea existed for EMTs including the job condition, improved treatment and working environment for them. Conclusion. In conclusion, we strongly suggest that the problems pointed out must be revised and corrected. Current usage of EMS fund needs to be redirected predominatly to pre-hospital EMS system. Otherwise, unless current management and investment of emergency medical funds in S. Korea are applied and used for the vital necessities and demands of EMTs, public EMS units and private EMS units as well as related units in pre-hospital EMS system as in the cases of United States, in our consideration, they must be suspended or abolished.

산업디자인에서 디자인 대상에 대한 철저한 분석과 이해는 필수적인 선행요건이다. 그러나 디자인 프로세스에서 이러한 고려사항을 모두 충족시키고 우수한 제품을 디자인하기 위한 가이드가 되는 데이터를 얻기란 쉬운 일이 아니다. 이에 본 연구에서는 직교배열표를 이용하여 신뢰도를 높일 수 있는 산업디자인 기초모델을 제안한다. 특히 실험을 간편화하고 결과치의 유효성을 높이고자 하는 직교배열표 본래의 목적은 산업디자인 프로세스에서 충분히 달성함과 동시에, 디자인 프로세스의 동시화로 디자인 요소의 비정량적 데이터를 정량화하고 그에 대한 상호작용에 대해서 알아보았다. 이 방법은 또한 산업디자인에서 고려사항을 도출할 수 있는 방법을 제시함으로써 디자이너들이 제품개발에 있어서 더 완성도가 높은 제품을 개발할 수 있고, 데이터를 실증해 보임으로써 정확한 판단을 내리는데 도움을 줄 수 있다.

The modular apartment has been completed for the first time in Korea through the national research and development (R&D) project in December 2017, and 30 households moved in. Although conditions such as technicality and constructability have to be satisfied to adopt and spread the modular apartments in the future, economic feasibility is the most important factor among the conditions. The economic feasibility of modular apartments can be compared with that of existing reinforced concrete (RC) structure apartments. It is highly important to reduce the construction cost through standardization above all. The standardization refers to establishment of national design standards and principles, and it is important for manufacturers and building companies to comply with those standards and principles. The modular construction (MC) skill in Korea is at an early adoption stage and the MC market is not widely expanded yet. Thus, the application of the MC design, which is the basis of the standardization, has not been widely accepted. However, related R&D projects are now performing mainly by the Ministry of Land, Infrastructure, and Transport to promote modular apartments in recent years and the design standardization standard (draft) is now prepared to be notified as a result of the steady research. Furthermore, pilot complexes for demonstration purpose are under construction, starting from public rental apartments. Thus, MC method-applied public rental houses will be spread in near future. This study aims to investigate the current design status in the Ga-Yang Housing as a pilot modular complex to produce and supply more economical and efficient modular houses, and analyze the problems by comparing the design standardization standards with pre-notified design standardization standards and summarize the modifications between them thereby presenting foundational data for establishment of the design standardization in the modular business industry.

Purpose: Many people recognize the fact that women are basically poor at financial and retirement planning. A small number of scholars have explored the factors and situations that influence the level of awareness of pre-retirement women and men with regards to planning for their retirement years. In most developing countries, including Malaysia, there are more men in the younger segment of the population and more women in the older segment, since women tend to live longer than men due to having jobs of relatively lower risk, their behaviors, and activities. Research design, data and methodology: Given that it is hard to predict whether they will be healthy in old age, women may require additional resources to obtain the care and assistance that they need. The transition from career life into retirement is a long process for people to go through. Some may be able to prepare for the next stage of life, and some may not be able to prepare due to personal reasons. Planning for future retirement is important because it will affect the quality of a woman's life after a certain age. Results: Without proper planning, women may face financial instability, depression, and poor psychological well-being. However, many women are unaware of their financial status or do not know their family's financial status, such as tracking the main income, budget, and expenses, financial commitments and have no proper record of assets owned, loans owed, or updated loan balances. Conclusions: The findings of this research have led to the conclusion that pre-retiree women are likely to regard their retirement savings as sufficient without realizing that they should have at least several types of savings instead of just one, and the grave consequences of not having any savings at all for their retirement years.

In order to reduce the booming noise caused by first bending mode of a drive shaft, this paper proposes a simulation program for prediction of the bending mode frequency of any tubular shaft. This program consists of a pre-processor for modeling of geometrical shape of the drive shaft with boundary conditions of various joints, a processor for constructing of global finite element matrices using beam elements and an eigen-solver based on MATLAB program. Using this simulation program, the effective and accurate FE model far a shaft attached to vehicle can be obtained by aid of database for stiffness of each joint. Thus the resonance frequencies and mode shapes of a shaft can be calculated accurately. Because the effect of the resonance on interior noise can be verified, more improved shaft will be proposed at the early stage of design.

This paper presents sensor network based autonomous vehicle system using a proposed image processing algorithm. The proposed image processing algorithm consists of pre-processing and five-stage image processing: coordinate calculation, driving area decision, line segment calculation, steeling decision, and acceleration decision. We evaluate the performance of the proposed algorithm on both straight road and curved road. Experimental results indicate that the proposed algorithm works well for autonomous vehicles. However, control accuracy of the proposed algorithm decreases as speed is increasing.

The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. And the prefab building method is very effective because the pre- manufactured building components is simply assembled to making up buildings in the construction fields especially the sandwich panel. Architecture considerations for the integration of PV module to building envelope such as building structure, construction type, safety, regulation, maintenance etc. have been carefully refelected from the early stage of BIPV module design. Trial product of BIPV module are manufactured and sample construction details for demonstration building are purposed. Therefore, this paper intends to advanced its practical use by proposing how to get integrated PV system which can be applied to prefab building material, and how to apply it.
