Objective : To investigate the actual driving state of the stroke patients who had assessed CPAD. Methods : We conducted a follow-up survey with 48 stroke patients who had assessed CPAD. First, we reviewed the medical chart and then carried out the telephone survey. Results : Of the 48 subjects, 12 were driving and 36 were not driving. Current drivers' CPAD score, it was 54.13, was higher than non-drivers' CPAD score(p<0.05). Those who passed the CPAD were driving more than who failed(OR=8.3, 95%CI=1.931-35.558). Conclusion : The pass group of CPAD have higher chance of driving than fail group and have lower chance of car accidence than fail group. Thus we can apply the CPAD for driving cognitive evaluation tests.

Today, the need for alternative energy has increased due to the global environmental problems and energy depletion. In order to solve a global environmental matter and an energy issue simultaneously, the application of the renewable energies in building has been constantly demanded. therefore, we must develop new energy resources that are abundant and provide substitutes for fossil fuels and we must study the application method of the renewable energies in building. Among renewable energies, the solar energy(photovoltaic system) is clean, inexhaustible, and available everywhere in the world and is judged to have the application possibility in building. Daegu city has a plan of putting a photovoltaic system on large buildings. For instance, EXCO, exhibition and convention building, and dormitory in Kyungpook National University, Dongho elementary school, Osan building in Keimyung University, Young korea academy in Daegu, are on the process of having a photovoltaic system. Therefore a study on the performance of photovoltaic system is important for the system design and maintenance. this paper describes the first invest cost, and performance test of the 95kW utility-interactive photovoltaic power system.

The purpose of this study is to provide some basic information for elderly driving safety, by analyzing the current state. This study analyzed 128 survey questionnaires given to senior welfare center user in P city and evaluated Montreal Cognitive Assessment Korean Version(MoCA-K) and Neurobehavioral Cognitive Status Examination(NCSE) for checked 41 owner drivers by questionnaires. 32% of total elderly persons was owner driver, and 56.1% of elderly drivers was driving everyday. 56.1% of elderly persons was driving for 1-2hours per day. 46.3% of elderly persons was using a car for leisure activity and 31.7% of elderly drivers was experienced a car accident. As cognitive function evaluation, some elderly drivers showed scores lower than average in subcategories of cognitive functions for driving a car. So, methodical evaluation system for accurate evaluation of deficit ability and driving re-education system will be required for safety driving of elderly person. In future, a legal approach of government as driver licence management and renewal system will be required for safety driving of elderly person.

교통안전공단이 운전자 400명을 대상을 졸음운전 실태를 조사한 결과 최근 1주일간 10명 중 4명이 졸음운전을 경험했으며, 그 중 19%는 사고가 날 뻔한 '아차사고' 경험이 있는 것으로 나타났다고 밝혔다. 이에 따라 운전자들의 졸음운전을 예방하기 위한 시스템의 존재가 시급하다는 것을 알 수 있다. 이에 본 논문에서는 운전자의 졸음운전 사고를 예방하기 위한 운전 방지 기법을 제시한다.

This study has aware of the seriousness of public official. and come up with an effective counterplan about public official. This research is a study on previous research on government and officer crime. And understanding is the status about public official. It proposed ways to solve the problem Drunk driving is illegal to drive a vehicle while drunk act. Drunk driving is likely the potential to cause a traffic accident. As a result, drinking and driving is decreasing since the mid-2000s. The cause of the change is to strengthen social awareness, regulations for drunk driving. and public official was decreased. However, it did not disappear. Cause of drunk driving is wrong, such as dinners and cultural distrust of the deputy driving, drinking after misjudgment on his physical condition. public official is a bigger influence. It is a social problem. Personally great damage to organization. Therefore, this study is an analysis of international practices and domestic best practices. Officials drunk driving drunk driving prevention measures are proposed to strengthen preventive measure, it is proposed the organization of internal control measures, union officials supporting the improvement of company dinner.

포항제철소는 제품의 선적 및 하역업무를 위래 13기의 하역기를 운영 중에 있다. 제품하역기의 운전실태는 1명의 작업자가 탑승하여 제품이 놓여질 선박 내 location을 관리한다. 특히, 중량물을 다루는 만큼 안전사고 방지를 위산 고도의 주의를 요하는 작업이다. 그러나 운전실의 위치가 지상 $13\~24m$에 위치해 있어, 하방 관측을 위해 장시간 머리를 구부려야 하므로 작업피로는 물론 요통 발생 가능성이 높다. 또한, 13기 하역기의 제작사 및 제작 시기에 차이가 있어, User Interfare가 각기 다르다. 주기적으로 하역기를 바꿔 탑승하는 작업자로서는 오조작 가능성이 있어 문제점으로 지적되고 있다. 근본적으로는 이동통로 폭의 협소함에 따른 진$\cdot$출입의 문제, 전장품의 부적절한 배치에 따른 작업자 충돌 문제 등, 기본적인 인간공학적 원칙이 반영되지 않은 운전실설계로 제품하역기 작업자의 업무부하가 가중되고 있는 실정이다. 본 연구에서는 인간공학적 설계원칙을 반영하여 제품하역기 운전실을 가상환경으로 제작해보고, 3차원 인제 모형을 실제로 탑승시켜 주요 설계 제약조건의 검증을 실시하였다. 3차원 가상환경 및 인체모형의 제작은 상용 3D Tool인 3ds Max 5와 Anthropos Ergomax라는 프로그램을 이용하였다. 이와같은 방법을 통해, 실제 공사 후에 발견될 문제점에 대한 사전 도출이 가능함은 물론, 보다 인간공학적인 운전실 설계가 이뤄질 수 있었다.

2009년 부산의 한 고속도로에서 8중 추돌사고가 발생했다. 40대 남성이 운전 도중 저혈당 상태에 빠져 일어난 사고였다. 당뇨병환자라면 흔하게 저혈당을 경험하지만 그 위험에 대해서는 모르고 있는 경우가 많은 것으로 드러났다. 한독약품과 한국 노바티스에서 실시한 저혈당 인식 실태 조사결과{2010년)에 따르면 당뇨병환자 10명 중 7명 (74%)이 저혈당에 대해 잘 모르고 있는 것으로 나타났다. 또한 주의가 필요한 야간 저혈당증 및 저혈당 무감지증을 겪은 당뇨병환자도 각각 37%와 44%를 차지했다.
