The performance of insulators under contaminated conditions is the underlying and the most factor that determines insulation design for outdoor applications, Among the contamination factors, The sea salt is the most dangerous factor, and the salt factor have closed relation with climatic conditions, such as wind, temperature, humidity and so on, Effect of these factors to insulation system is different of each other, and need to show the correlation by multiple regression analysis techniques. In this paper, predicted and analyzed equivalent salt deposit density (ESDD) by change climatic condition through multiple regression analysis.

Recently, child safety map making education has attracted attention as a way to reduce crimes against children. In Korea, the Ministry of Gender Equality and Family organized a child safety map making education program in 2011. The program's manual was revised in 2013 and the Ministry implemented it as a project to promote the rights of women and children. Child safety map making education aims to raise a child's understanding of their neighborhood, to have voluntary control and normal consciousness as a local inhabitant, to be aware of wrong behavior and crime, and to be part of creating a safe urban environment. However, when compared to educational programs in other major developed countries, the child safety map making education program in Korea currently does not improve a child's awareness of their surroundings. In this workshop study, we proposed and ran a new program to improve children's awareness of their environment based on the active participation of children in the existing safety map educational program. The workshop was held for 4 weeks for 48 students from 5th and 6th grade at Osan Daeho Elementary School. We analyzed this new program's effects with the following results. First, an analysis of the effects of the program on children's recognition of safe and dangerous spaces revealed that their understanding of these spaces increased by 30.4% after the workshop. The safety-related factor in the mind map key concept increased from 0.94 to 4.94, indicating that the children's perception of neighborhood risk and safety factors improved. Second, the analysis of the effects of the program on the children's coping ability in dangerous situations showed that their understanding of how to deal with dangerous situations increased by 11.3%. The children's understanding of facilities they could ask for help, such as police boxes and child safety guard houses, improved by 17.9%. Third, analysis of the effects of child safety map making education on children's understanding of their neighborhood, their perception of responsibility in the neighborhood, and their neighborhood attachment showed that these levels of children's understanding of the neighborhood improved by 6.0% after the workshop.

본 연구에서는 충청북도 내 각 지자체를 대상으로 지역별 대설특성을 통한 잠재적 위험요인을 분석하였다. 분석결과, 35년 평균적설량으로 인한 잠재적 위험도는 제천시와 보은군이 가장 높았으며 35년 최대적설량을 통한 잠재적 위험요인에서는 다른 결과가 도출되는 것을 알 수 있었다. 잠재적 위험요인에 대한 지역의 빈도수를 살펴보면 가장 높은 지역은 보은군, 제천시, 괴산군, 영동군, 청주시 순으로 도출되었다. 본 연구는 일반적인 대설특성 뿐만 아니라 잠재적인 위험요인들을 도출하고 그에 대한 위험도를 제시하였다는 점에서 그 의의를 가진다. 본 연구의 결과는 향후 충청북도 각 지자체들의 제설대응체계 및 방안 마련에 기초자료로 활용할 수 있을 것이다.

본 연구에서는 디지털 미디어 과사용 여부를 측정하는 인터넷(IOS-Q), 게임(GOS-Q), 스마트폰(SOS-Q) 과사용 선별 질문지를 대규모 일반 청소년 집단을 대상으로 타당화하여, 선별검사 장면에서 활용할 수 있는 유용한 검사 도구를 제시하고자 하였다. 이를 위해 총 9,336명의 중학생(남 4,796명, 여 4,540명)을 두 개 집단으로 구분하고 확인적 요인분석과 탐색적 요인분석을 각각 실시하였으며, 타 지역에서 모집된 초등학생 4,536명(남 2,260명, 여 2,276명) 및 중학생 6,551명(남 3,013명, 여 3,538명)을 대상으로 한 번 더 확인적 요인분석을 실시하였다. 세척도 모두 네 개 하위요인으로 구분되었으며 IOS-Q는 17문항, GOS-Q는 19문항, SOS-Q는 18문항을 포함하였다. IOS-Q와 GOS-Q의 하위요인은 심리적 의존, 문제를 인식함에도 조절실패, 위험한 사용, 다른 영역에의 흥미 감소로 명명되었고, SOS-Q의 경우 위험하고 강박적인 사용, 문제를 인식함에도 조절실패, 다른 영역에의 흥미 감소, 금단/내성으로 명명되었다. 이들은 모두 행동중독이나 충동조절장애의 주요 특징들을 잘 반영하는 것으로 보이며, 내적 합치도 역시 .880-.915로 우수한 편이었다. 이어서 고위험군을 선별하기 위한 절단점을 탐색하고자 잠재프로파일분석과 ROC 분석을 실시하였고, IOS-Q 30.5점, GOS-Q 31.5점, SOS-Q는 36.5점이 최적 절단점으로 제안되었다. 끝으로 연구 의의와 한계점을 논하고 후속연구를 제언하였다.

This research is the concept of a game addiction absorbed in the game based on the review and analysis of factors that affect the characteristics of game addiction, it is appropriate to extract the purpose of factors. Game addiction factor is composed of a total of 32 questions, and a total of 356 people, to collect data through surveys. Factor analysis of the collected data to the target as a result of physical and mental problems, loss of control, tolerance, and avoidance of real world consists of three sub-factors. Factors that affect flow of tolerance and loss of control, and avoid the real world, including two sub-factors that could determine. Diagnostic game addiction factor in the reliability coefficients (Cronbach alpha) is a robust .966 aspects in the event. The game addiction scale score of 90-game addiction by category 'regular user', 90 points and 114 between the terms 'potentially dangerous user' and 13 percent of the overall. Finally, more than 115 points in the 'high-risk user' has been classified as 5% of the overall distribution of the notice that. Such factors extract game is a game addict, addicted users of the game and tend to properly evaluate and navigate game addiction-related problems early in the game addiction and found it could be used properly.

A driving simulator is a computer-controlled tool to study an interface between a driver and vehicle response by enabling the driver to participate in judging vehicle characteristics. Using the driving simulator, human factor study, vehicle system development and other research can be effectively done under controllable, reproducible and non-dangerous conditions. An Adaptive Cruise Control (ACC) system is generally regarded as a system that can be achieved in the near future without the demanding infrastructure components and technologies. ACC system is an automatic vehicle following system with no human engagement in the longitudinal vehicle direction. And the influence of the driver is substantial in developing the system. Driving characteristic is very different according to the accident riskiness, gender, age and so on. In this research, experiments have been carried out to investigate driving characteristics with the ACC system, using a driving simulator. Participants are 21 male and 19 female. Driving characteristics such as preferred headway-time, lane keeping ability, eye direction, and head movement have been observed and compared between the driving with ACC and the driving without ACC.

Recently, as value for practical use of big data is evaluated, companies and organizations that create benefit and profit are gradually increasing with application of big data. But specifical and theoretical study about possible risk factors as introduction of big data is not being conducted. Accordingly, the study extracts the possible risk factors as introduction of big data based on literature reviews and classifies according to big data processing, data collection, data storage, data analysis, analysis data visualization and application. Also, the risk factors have order of priority according to the degree of risk from the survey of experts. This study will make a chance that can avoid risks by bid data processing and preparation for risks in order of dangerous grades of risk.

Our city structure is being complicated from the development of industry and the increase in population. It makes the ground space overcrowded, so underground space is systematized for use. Because this underground space has very complicated configuration, people have difficulty in finding the route in the underground space. Therefore It is demanded to comprehend configuration of the various space structure, predict pattern of the moving and analyze induction factor of the moving. When people are in the conflagration or dangerous situation, they are in the habit of using the route which they are used to go to and from. It is needed to analyze moving pattern of the pedestrian who usually use the underground space for the sake of dealing with conflagration in the underground space. Finally, this study suggested that general characteristic, distribution, moving route of the pedestrian and factors influencing that they choose the route which the research finds out.
