최근 건설현장에서는 안전사고 예방을 위한 다양한 노력을 하고 있지만 전 산업에서 건설업 재해율은약 50%로 여전히 높은 비율을 차지하고 있다. 중대재해처벌법 시행(22년 1월 27일)과 4차산업 발달에 따른 IOT기반 안전관리 등 안전규제와 안전관리기술이 현장에 적용되고 있지만 건설현장 안전관리의 접점에 있는 실무자 및 근로자가 실효성 있게 안전관리활동을 하고 실질적으로 안전행동을 강화시키는 안전사고 예방적 안전관리가 부족한 실정이다. 본 연구에서는 건설현장에서 시행되고 있는 안전보건활동, 안전교육, 안전행동강화, 안전성과와의 구조방정식모형(SEM)을 제시하고 관계 분석하였다. 건설현장 실무자 및 근로자의 설문조사 데이터를 구조방정식에 적용하여 관계를 분석한 예측결과, 분석결과에 의해 검증된 가설이 시사하는 부분을 해석하고, 가설검증을 기반으로 외생변수로부터 안전행동강화에 도달하는 경로를 탐색하고 주요 논점을 논의한다.

영구자석을 사용한 마커가 설치된 자기장 이동 경로에서 이동 로봇의 경로 인식을 위한 위치인식 시스템이다. 저가의 홀센서를 일정 간격의 열로 배치한 센서를 설계 제작하고, 그 센서를 이용하여 측정된 마커의 자계 값을 이용하여 경로상의 위치를 인식할 수 있도록 하였다. 마커의 극성을 인식하는 새로운 방법을 제시하고, 인식된 극성을 코드화하여 경로상의 특이점들에 배치함으로써 경로 이동 중에 그 점들의 위치를 인식하도록 하였으며, 로봇은 그 위치에서 미리 정해진 행동을 하도록 프로그램 하였다. 센서들 간의 통신 방법을 논하였고, 각 센서들에서 얻어진 정보로부터 이동 로봇의 경로상의 위치인 측방향 변위 오차와 방향각 오차를 기하학적으로 산출한다.

The purpose of this study was to investigate the determinants of customers' information engagement, the behavior pattern from WOM to cooperation, and the moderator in the behavior pattern. The proposed three determinants, boundary personnel's citizenship behavior, satisfaction, and commitment were significant antecedents to WOM, but not to cooperation. The path coefficient from WOM to cooperation was significant and hereby the voluntary level of cooperation was found as a higher level of voluntary behavior than WOM. Additionally, the path from WOM to cooperation was moderated by customer involvement, as the path coefficients from WOM to cooperation varied by the level of involvement.

The market participation and development of major manufacturers of next-generation green vehicles is accelerating in recent years. The results of this study are as follows: Consumer type (personal value pursuit type, price value pursuit type) was significant difference between consumer. The results of this study were as follows: First, there was no significant difference in the characteristics of consumers (gender, age, monthly average income) and purchase intention according to age, gender and monthly average income, Image has a positive (+) impact on eco-friendly vehicles. This suggests that the development and market participation of next - generation green vehicles is accelerating and consumers 'interest is increasing, and the characteristics of environment - friendly vehicles and the government' s policy support are important factors.

This study investigates the impact of the attributes of the eco-friendly agricultural products traceability system on perceived value and behavioral intention. Empirical subjects are those who live in Seoul and Gyeonggi province, over the age of 20 and have experience of buying eco-friendly agricultural products though department stores, discount stores and specialized eco-friendly product stores. After distributing 550 copies of questionnaire from April 10th, 2013 to May 9th, 2013, 470 copies(85.5%) are used for a final statistical analysis of the survey after excluding the copies with biased opinions or missing values. The results of this study show sufficient theoretical base for future research by verifying a causal relationships between the attributes of eco-friendly agricultural products traceability system such as reliability, safety and innovation, and consumers' perceived value and behavioral intention. Therefore, producers should correctly record producing history base so that consumers can continue to use the system. The traceability system can not only satisfy consumers by enhancing transparent management and producing systems for eco-friendly products but also guarantee us to eat all products we get without worries.

경로 계획은 에이전트가 로봇이 특정 목적지에 도착할 수 있도록 에이전트가 수집한 정보를 바탕으로 경로를 설정하는 작업을 뜻한다. 부분 관측만 가능한 맵인 경우 에이전트 이동마다 새로 수집되는 정보들을 바탕으로 마르코프 의사결정 과정을 사용한 가치 반복 알고리즘이 널리 사용되지만, 제안된 가치 반복 알고리즘 사용 시 매 행동마다 모든 공간의 최적 경로를 계산하기 때문에 시간이 오래 걸리는 문제점이 있다. 이에 본 논문에서는 에이전트가 한 번에 탐색하는 범위가 제한되어 있다는 점에 착안하여 탐색 반경 내에 속하는 공간의 가치 함수 값을 미리 추정하여 효율적으로 최적의 경로를 추정하는 가치 반복 알고리즘을 제안한다.

알츠하이머병은 치매의 주요 원인 중 하나로 기억, 판단, 언어 등의 지적 기능의 감퇴뿐만 아니라 인격, 행동양상 장애 등을 동반하며 결국은 환자를 죽음에 이르게 하는 위험한 병이다. 본 연구는 뇌 백질의 비등방성을 잘 보여줄 수 있는 확산 텐서 영상 (diffusion tensor imaging; DTI) 데이터로 부터 신경섬유 경로를 생성하고, 알츠하이머병 환자와 정상인의 신경섬유 경로의 특징을 비교 분석 하였다. FSL 프로그램을 사용하여 생성한 신경섬유 경로에서 알츠하이머 환자와 정상인 집단간의 신경섬유 경로는 부피와 밝기에 커다란 차이를 보인다. 특히, 신경섬유 경로의 부피에서 현저한 차이가 있다는 점은 알츠하이머의 조기 진단에 유용하게 사용될 수 있다.

This study was conducted to propose anti-stigma strategies by verifying the social stigma on behavioral addiction under the premise that social stigma is a main obstacle to the treatment of addiction. A research model was constructed by applying the attribution affection theory and the modified attribution affection theory, which are very useful for explaining emotional and behavioral responses to the persons with mental illness. In other words, when attributing the causes of behavioral addiction to the personally controllable things such as personality, will and lifestyle, social distance can be increased by the mediate of anger. However, when attributing the causes of behavioral addiction to biological factors that can not be controlled by an individual, there can exist two pathway, one is the arising of helping behaviors by the mediate of sympathy (the attribution affection theory), and the other is the aggravation in the social distance due to rising fear (the modified attribution affection theory). In order to verify the research model, 383 adult subjects mainly in South Gyeongsang Province were randomly presented with the vignettes of gambling addiction and internet game addiction, and asked about the causes of the problems and their emotional, prejudicial, and behavioral responses to them. As a result, all pathway had statistically significant predictive effect. Therefore, in the case of attributing to personal causes, social distance increased by the mediate of anger. In the case of attributing to biological causes, both pathway had significant predictive effect, but the indirect effect of the pathway predictive of the helping behavior by the mediate of sympathy was greater. Researchers suggested that anti-stigma strategies, which emphasize that behavioral addiction is a mental health problem requiring treatment, are necessary.

In this study, factors influencing the parking policy compliance (i.e. levying a garage option on car buyers) were identified, and then, were applied to the theory of planned behavior. To find out the influence of factors and their path, the study built a parking policy compliance model using structural equation modeling. The independent variables such as attitude, subjective norm, perceived behavioral control had positive effects on the parameter describing the efforts to secure his garage, but the parameter impact on the dependent variable was not significant. In the end, the independent variables affected the dependent variable was not significant. The perceived behavioral control utilizing regulations had positive effects on the parking policy compliance behavior, but past behavior such as street parking and prowling to find a free parking space had a negative effect on parking policy compliance behavior.

The purpose of this study is to identify the optimal model to explain safety behavioral intention according to the recognition of safety communication in cabin through comparison of Planned behavioral theory and Triandis' theory of interpersonal behavior. In order to accomplish the study purpose, research model and hypothesis were established based on the previous research. As a result of the analysis, it was found that attitude and Perceived Behavioral Control had a positive effect on the safety behavioral intention. Triandis theory shows that social factors and habits have a positive impact on safety behavioral intention. In addition, A comparison of the two models confirms that both psychological processes of recognition and emotion are accompanied by the relationship between safety information awareness and safety behavioral intention.
