The purpose of this research was to get an alternative idea about the situation and problems of domestic pest control company We performed a questionnaire survey of 105 companies to find the situation and problems of pest control companies with and with out lincensed sanitarians. The investigation revealed the following issues and the conclusions summarized. 1. Companies with lincensed sanitarians have shown to put forth hygenic safety(62%) as first priority as to companies without sanitarians neglect hygenic safety and rank financial benefit(40%) as their priority. 2. Companies with lincensed sanitarians have directions on its use of pesticides but the companies without inspectors rely only on field experiences. 3. Companies with lincensed sanitarians are known to use the safety equipment. To the contrary, companies without sanitarians worked without the proper safety equipment safety gear. 4. Companies with sanitarians been regularly received educational Programs on chemicals used in the pest control. And then companies without did not have my other educational programs for chemicals they used.

Purpose The purpose of this paper is to observe the relative priorities of importances among IT services for Smart tourism as well as the relative priorities of importances among ways for developing the IT Services. Design/methodology/approach AHP analysis model was designed with 3 layers in order to recognize the relative importances priorities of IT services and the ways developing the IT services in Smart tourism. The factors in the top layer consist of Pre-trip IT services, During-trip IT services and Post-trip IT services. The lower factors in second layer of the Pre-trip IT services consists of Tourism information search, Online reservation and Price comparison. The lower factors of the During-trip IT services consists of Context recognition, Virtual Reality and Drone Application. The lower factors of the Post-trip IT services consists of Interactive Sharing and Tagging. The factor of third layer, the ways of developing the IT services consist of Company leading, University leading and Industry-University Collaboration. The structural questionnaire based on the AHP analysis model was designed and used to survey experts in IT and tourism areas. The collected data by the question investigation was analyzed by AHP analysis technique. Findings The importance priority of During-trip IT service was highest among in the three type IT services of tourism life cycle. The importance priority of Price comparison service was highest among IT services for Pre-trip. The importance priority of the Context recognition service was highest among IT services for During-trip. The Interactive sharing service was highest among IT services for Post-trip. It would be confirmed for the IT service development ways of Company leading to be suitable for most of the It services, such as Tourism information search, Online reservation, Price comparison, Context recognition, Virtual reality, Drone application, Interactive sharing.

주도로 차량 위주의 좌회전감응신호운영은 보행대기시간은 더 늘어날 수 있기 때문에 이는 보행자의 불편 또는 스트레스를 유발하고 있는 실정이다. 따라서 본 연구에서는 좌회전감응신호 적용 전·후의 보행대기시간과 설문조사를 통해 보행자가 느끼는 스트레스를 살펴보았으며 이를 개선하기 위하여 보행자우선 감응신호 시뮬레이션(VISSIM) 분석을 하였다. 좌회전감응신호 적용 후 보행대기시간은 비첨두시간에 37% 증가했다. 설문 결과 보행대기시간이 길어졌다가 62.1%, 그 중 78%는 그로 인하여 스트레스를 받는거로 나타났다. 한편 보행자우선 감응신호 시뮬레이션(VISSIM) 분석 결과, 차량 통행속도는 1.07km/h(2.5%)로 소폭 감소한 반면 보행 평균대기시간은 15.51초(28%) 감소하여 크게 개선되었다. 따라서 보행자우선 감응신호는 보행 대기시간을 감소시켜 보행자 스트레스를 완화할 수 있을 것으로 기대한다.

우리나라의 형사재판제도는 2008년 형사소송법이 개정되면서 공판중심주의로 커다란 전환점을 맞이하게 되었다. 배심원제도라고 할 수 있는 국민의 형사재판 참여제도가 본격화되면서 국민의 법 제도에 관한 수준이 향상되었고, 형사 재판에 참여하는 국민(배심원)들의 수준에 맞는 형사재판의 진행과 설명, 과학적인 증거의 제시를 통한 증거주의 재판이 실현되고 있는 것이다. 이에 검찰에서는 과학적 조사기법과 수사의 과학화를 위한 한 방편으로 영상녹화제도를 도입하게 되었고, 부가적인 지원절차로서 컴퓨터 속기사를 전국 검찰청에 상주시킴으로써 영상녹화를 통하여 진술된 내용의 문서화를 지원하고 있다. 이에 본 논문에서는 컴퓨터속기제도를 국내외적으로 살펴보고 우리나라에서 과학적 조사기법으로 전개되고 있는 영상녹화제도속의 컴퓨터속기의 미래를 전망 해본다. 본 논문을 통하여 검찰에서 지양하는 과학조사를 위한 영상녹화제도에서 컴퓨터 속기가 차지하는 역할과 전망을 살펴봄으로써 조사기법의 선진화를 촉진하고, 인권보호, 공개재판중심주의에서 컴퓨터속기의 중요성과 위치를 재조명할 수 있다.

PURPOSES : The purpose of this study is to suggest a specific investigation guideline to decide priority of repairing old concrete pavements that pile up substantially. METHODS : In this study, a principle of division of homogeneous sections was proposed to reflect the characteristics of the pavement reasonably in the specific investigation results. In addition, a checklist and guideline of field investigation were suggested for the old concrete pavement sections, which require inspection toward their durability and structural performance. Furthermore, the items of laboratory test necessary to the old concrete pavement were suggested based on the existing laboratory test considering characteristics of the old concrete pavement. The present condition of the old concrete pavement could be analyzed by the test results. RESULTS : A method of division of homogeneous sections suitable for the specific investigation of the old concrete pavement was suggested. The proportions of distress severity of pavement sections were compared by distress type to figure out the present state of the old concrete pavement. Scaling, durability cracking (or alkali-silica reaction), and longitudinal spalling were selected as the most severe distress types. The detailed positions of the sections were also suggested. The checklist of the specific investigation was categorized by field survey and laboratory test, and its evaluation criteria were proposed. The three types of the sections of durability cracking (or alkali-silica reaction), bridge connection, and asphalt overlay were selected as the sections of the field survey. The compressive strength, void structure, and chloride penetration depth were suggested as the items of the laboratory test. CONCLUSIONS : A fundamental level of the guideline was suggested in this study to resolve the problem of old concrete pavement. Appropriate guidelines related to the repair of the old concrete pavement should be provided by performing additional research efforts.

Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

Carbonation in RC (reinforced concrete) structure is considered as one of the most critical deteriorations in urban cities. Although RC column has one mix condition, carbonation depth is measured spatially differently due to its various environmental and internal conditions such as sound, cracked, and joint concrete. In this paper, field investigation was performed for 27 RC columns subjected to carbonation for eighteen years. Through this investigation, carbonation distribution in sound, cracked, and joint concrete were derived with crack mappings. Considering each related area and calculated PDF (probability of durability failure) of sound, cracked, and joint concrete through Monte Carlo Simulation (MCS), repairing timings for RC columns are derived based on several IPDF (intended probability of durability failure) of 1, 3, and 5%. The technique of equivalent probability including carbonation behaviors which are obtained from different conditions can provide the reasonable repairing strategy and the priority order for repairing in a given traffic service area.

Development of the economy and the growing income of people interested in the leisure and health has been focused. Past the town common wells and groundwater around the water, but health is a priority these days to solve the drinking water directly from tap water, but most people work from home, through the water purifier has been resolved. Depending on seasonal changes and personal taste of coffee, if you can enjoy a snack and water purifier is a restaurant, lounge, public areas and focusing on the rapid spread of the fire, water purifier as compared to the total number of fires increased by 0.03% per year trend on, but the washrooms fire and fire-related research data and case studies with analysis of the exact cause lack of proper preventive measures are insufficient reality. In this study, focusing on electrical energy using a water cooler to understand the structure and principles of fire, the fire revealed the mechanism is vulnerable to the consideration of factors, the exact cause of the fire investigation and the Assistant, manufacturing defects, and to contribute to fire prevention review should.
