  • This study proposes a third-person virtual reality content production pipeline to provide users with a new experience and presence in a new virtual reality environment. For this purpose, we first create third-person virtual reality content, which includes a story, fun factors, and game characteristic. It consists of a tutorial scene in which a user can pre-learn the proposed interface suitable for a third person different from existing virtual reality content and a content scene that achieves its purpose by using game factors based on the background story. Next, we design an interface suitable for the third-person virtual reality content. This study proposes an interface in which users can interact with a virtual environment or object by using their hand. The proposed interface consists of three steps: character movement, virtual object selection with multiple selection, and 3D menu control using virtual space. Finally, through the survey experiment, third-person virtual reality content produced based on the proposed interface was confirmed to be easily controlled while ensuring high satisfaction.

  • The purpose of this study was to examine the convergent awareness of emergency medical technicians serving as paramedics on the standard operating procedure(SOP) and their performance of it. The subjects in this study were 400 selected emergency medical technicians who were working as paramedics, and SPSS 20.0 was employed to make an analysis. The findings of the study were as follows: As for the convergent awareness of the subjects, they were best aware of the prevention of respiratory infections, and they were least aware of hand hygiene. Concerning performance, they performed best in handling treatment equipment and ensuring staff safety, and they performed least well in terms of hand hygiene. Overall, they were rated higher in awareness than in performance. Second, regarding the influence of general characteristics, there were statistically significant differences in awareness according to age, gender and injury experience, and significant differences were found in performance according to career only. The convergent awareness of the emergency medical workers was positively correlated with their performance. Given the findings of the study, it's required to improve both the Standard Operating Procedure awareness and performance of emergency medical workers who serve as paramedics, and it's expected to make it possible to boost their performance when repeated education is provided with the kind of programs that aim at improving awareness.

  • The existing effective path-length model of ITU-R has some drawbacks: The prediction error is quite large compared to domestic measurement data and it is an empirical model in which the physical characteristics of rain cells are not considered. In this paper, a theoretical model for effective path-length using the rain-cell concept was proposed and its validity was verified using the measurement data. To analyze the statistical characteristics of rain cell parameters, the weather-radar data(CAPPI) measured by Korea Meterological Administration were analyzed and the correction factor was properly introduced to fit the Chollian beacon measurement data of ETRI(Electronics and Telecommunications Research Institute). To verify the proposed effective path-length model, it was compared with the Mugunghwa No. 5 beacon data measured in Chungnam National University with the support of ADD(Agency for Defense Development). It was confirmed that the prediction results of the proposed model are in good agreement with the measurement data.

  • 세계가 일일 생활권화 됨과 더불어 국제교류가 활발해지므로써 횡문화 간호 연구는 전문직 간호(Professional Nursing)에 있어서 매우 중요한 부분을 차지하고 있음을 많은 문헌을 통해서 알 수 있다(Brink, 1976 : Leininger, 1977 : Roberston & Boyle, 1987). 횡문화 간호연구는 서로 다른 문화적 배경을 가진 사람들을 잘 이해하고 그들의 건강을 돌봄에 있어서 더욱 효과적이고, 안전한 간호를 할 수 있을 뿐만 아니라 간호이론 개발, 간호모형(Model) 개발에 있어서도 매우 중요한 역할을 한다고 믿는다. 본 연구는 1984년에서 1987년 사이에 전문적 간호연구지에 실린 10편의 횡문화 간호연구와 관련된 논문들을 발췌하여 간호지식체의 본질적인 과정인 비판적 문헌고찰을 통해 각 논문들을 비교 분석 한 것으로써, 미래의 간호연구를 위한 간호실무, 간호교육, 간호연구 방법 및 간호 행정면에서 그 적용성을 높여줄 것이다. 비판적 문헌고찰을 위한 기준은 Burns와 Grove(1987)의 방법을 참고하여 아래와 같이 선정하였다. 1. 분석대상 : 목적, 가설 진술, 문헌고찰, 표본조사, 방법론적 논점, 결과 해석 2. 이론적 틀의 유도 흑은 통합 3. 발전적인 간호수행을 위한 중요성, 적용성 및 제언 이상의 내용으로 비교 분석을 해본 결과 1984년에서 1987년 사이에 발표된 횡문화 간호에 관한 논문들의 주제는 주로 여성을 대상으로 한 건강돌봄, 자가간호, 건강신념, 수유, 임신 그리고 간호사와 소수민족 노인과의 의사소통 양상 등으로 나누어 볼 수 있었다. 이론적 틀은 주로 사회학, 정신심리학, 인류학 이론으로부터 도출되었고, 오직 두 편만이 간호 이른에 틀을 둔 것으로 나타났다. 1. 10개의 논문의 가설과 목적의 분석에 있어서 4편의 논문은 목적과 가설이 구체적으로 진술되어 있었고, 나머지 6편은 목적이 전반적으로 진술되어 있었으며 가설도 구체적이지 않았다. 이러한 제한점은 각 논문의 연구자가 문헌고찰을 충분히 하지 못하고 단지 수편의 논문만을 제시 한 데서 비롯되었다고 분석 해 볼 수 있겠다. 2. 문헌고찰 부분에서는 각각의 연구주제를 지지해줄 수 있는 문헌들이 충분히 고찰되지 못하였고, 이론적배경 또한 횡문화 이론과의 관련성이 적었다. 또한 횡 문화 연구에 기초가 되는 연구대상자의 사회 인구학적 특성과 역사적 배경은 잘 나타났으나, 이론적 연구와 경험적 연구 간에 괴리가 있었다. 3. 표본추출방법은 문화에 기반을 둔 대상자를 선정한다는 점에서 한계성 이 있었다. 4. 방법론적 이유로는 대상자와의 면담시간이 구체적으로 기술되지 않았으며, 고유한 언어를 통역하는 과정에서 의미론적 문제에 대한 고려가 부족하였다. 면접과 기록과정에서 보면 자료의 기록과정과 분류 및 분석과정이 명시되어 있지 않았다. 참여관찰과 면접방법을 사용시 이에 대한 자세한 기술이 되어 있지 않았다. 5. 연구결과의 적용 및 이에 대한 논의는 상당히 제한되어 있었는데, 수편의 연구만이 방법론 문제점과 앞으로의 연구분야에 대한 전망을 제시하였으며, 특이한 것은 어 떤 연구자도 이른 개발을 위한 적용 및 임상실무적 차원에서 간호에 대한 제언을 하지 않았다.

  • This study develops a fusion priority signal control algorithm to pass without delay in emergency events. Fusion priority signal control is method combined center control with local control. The center control method applies signal times for each signalized intersection on the emergency vehicle's route when an emergency call is received. As signals are controlled before the emergency vehicle leaves for its destination, it is possible to clear the queues at each intersection more effectively. However, since the traffic information (speed, position) of the real-time emergency vehicle is not used, the intersection arrival time predicted by center control and actual arrival time of the emergency vehicle may be different from each other. In the case, it is possible to experience a delay caused by the signal. Local control method operate priority signal use the real-time information of EV, but there is a limitation that queue elimination time can not be reflected. In this study, fusion(center+local) control algorithm is proposed to compensate the disadvantages of center and local control also maximizing its advantages. Proposed algorithm is expected to decrease delay time of EV in emergency situation.

  • This study was carried out to find out if peripheral neuropathy was resulting from exposed to pesticides in farmers. Thirty four male farmers in rural area of Chungju were selected as a study group. According to the farm type and area, the group was subdivided into two groups: the high exposed group(n=20) and the low exposed group(n=14). Nerve conduction velocity tests were done on four nerves of the dominant arm(median motor, median sensory, ulnar sensory, and ulnar motor) and three nerves of the dominant leg(peroneal motor, sural sensory, and posterior tibial motor). On the nerve conduction study, all of the results were included normal range. But comparing to reference mean values, most of results were significantly decreased(P < 0.01 by t-test). And the median motor conduction velocity and the peroneal nerve latency were significantly increased in the high exposed group than the low exposed group and reference values. But we concluded that these findings are caused by age difference not pesticide exposure. In conclusion, we cannot find any abnormality of nerve conduction velocity caused by exposure to pesticide in this study group.
