최근 인터넷과 스마트 폰의 발달로 사용자들 사이의 관계를 통해 다양한 정보를 생성하고 공유할 수 있는 소셜 미디어 서비스가 활발히 이용되고 있다. 특히 정보의 양이 방대해지고 신뢰할 수 없는 정보가 증가함에 따라 사용자에게 필요한 정보를 제공해 줄 수 있는 전문가 추천 기법에 대한 연구들이 진행되고 있다. 본 논문에서는 사용자의 관심 분야, 인적 관계, 응답 품질을 고려한 전문가 추천 기법을 제안한다. 사용자의 관심 분야는 사용자가 소셜 네트워크상의 활동을 분석해 최신의 사용자의 관심 분야 지수를 판단한다. 사용자의 인적 관계는 소셜 네트워크상의 같은 관심분야의 사용자만을 추출하여 인적 관계를 구축하여 인적 관계 지수를 판단한다. 사용자의 응답 품질은 사용자의 응답 속도와 응답 내용을 고려하여 응답 품질 지수를 판단한다. 마지막으로 사용자의 관심 분야, 인적 관계, 응답 품질을 합하여 사용자의 전문가 지수를 판단하고 사용자의 질의를 분석하여 질의와 전문가 그룹을 매칭하여 전문가를 추천한다. 다양한 성능평가를 통해 제안하는 기법이 기존 기법에 비해 성능이 우수함을 보인다.

이 연구는 범죄에 대응하기 위하여 경찰의 정보활동 중 휴민트에 대하여 살펴보고, 휴민트의 특성을 고려하여 인적네트워크 수준이 휴민트 활용에 미치는 영향을 파악하기 위한 연구이다. 연구의 완성을 위하여 현직경찰을 대상으로 설문조사를 실시하여 얻어진 자료로 연구를 수행하였다. 휴민트는 대인간의 접촉을 통하여 얻어지는 정보를 의미하는 것으로 무형적인 접촉을 통하여 얻어지는 정보를 의미한다. 휴민트는 전달되는 속도가 빠르고, 상대의 은밀한 의도까지 파악할 수 있으며, 접근하기 어려운 정보에 접근할 수 있고, 기계를 사용하지 않는 경우가 많기 때문에 인간의 오감을 이용한 정보획득이 가능한 장점을 가지고 있다. 휴민트는 인간관계를 바탕으로 정보를 획득하는 정보활동으로서 인간관계는 휴민트 획득의 근간이라 볼 수 있다. 따라서, 경찰관의 인간관계를 독립변수라고 할 때 인간관계를 구성하는 인간관계 수준, 인간관계의 신뢰깊이, 인간관계의 폭이 휴민트 활용에 미치는 영향을 살펴본 결과, 인간관계의 폭이 넓을수록 동향을 파악하는데 효과적으로 이용하고 있는 것으로 나타났으며, 범죄에 대응하기 위한 정보를 활용하는 경우에도 인간관계의 폭이 넓을수록 효과적인 것으로 나타났다.

According to construction of global administration environment, all over the world was ended up in infinite competition period. Because eating out company also competes with another company, it must enjoy competitive power high position to secure high position continuously, classified by formation constituent's individuation and two aspects of organic special quality by the factor. Individuation classified by formation constituent's business ability, personal relations, age factors of Information Technology, and organic special quality classifies by factor of formation culture and result that analyze eating out company's business condition competitive power reinforcement effect factor is same as following. First, was construed by company culture, personal relations, business ability period of ten days with family Restaurant, and Information Technology showed that do not influence. Competitive power reinforcement effect factor with special restaurant was construed by company culture, personal relations, business ability period of ten days, and fast food company culture and Information Technology factor with hotel restaurant company culture by competitive power reinforcement effect factor construe.

In this paper, we propose new semantic contents modeling using individual features, associative relations and visual features for efficiently supporting browsing and retrieval of video semantic contents. And we implement and design a browsing and retrieval system based on the semantic contents modeling. The browsing system supports annotation based information, keyframe based visual information, associative relations, and text based semantic information using a tree based browsing technique. The retrieval system supports text based retrieval, visual feature and associative relations according to the retrieval types of semantic contents.

In the aftermath of the COVID-19 pandemic, the importance of collective efforts in promoting health preventive behaviors is accentuated, bringing sociopolitical factors into focus. To fully capture psychological drivers of health preventive behaviors in risk situations, anchored on the Model of Risk Information Seeking and Processing (RISP; Griffin, Dunwoody, and Neuwirth 1999), in retrospect of the recent COVID-19 pandemic, we explored whether and how individuals' vaccination behaviors are predicted by RISP-related variables (information insufficiency, affective responses, perceived information gathering capacity, subjective norms) and one's political identity. Findings from a survey of 705 adult participants in the U.S. showed that the effects of one's risk information insufficiency on his or her information seeking and affective response regarding the pandemic, which is also related to their risk susceptibility perceptions. More importantly, the impact of political identity on one's perceived risk susceptibility, and its association with vaccination behaviors are also identified. The findings of this study provide valuable insights for the development of effective health communication strategies for preventive health behaviors.

Decision-makers in ecological system and social system have complex interactions and relations. Such interactions and relations are not predefined but dynamically constructed. We consider what relation-s are constructed or destroyed and how the relations change. Therefore, we focus on the formation and collapse of relations as one of the emergent phenomena of social or ecological complex phenomena. Game theory is the best way of analyzing phenomena in terms of interactions. However, it is difficult to analyze the dynamical system by game theory. Consequently, we propose Selecting Game with agents as players based on game theory. In this model, the relations among agents are not predefined but constructed by selecting subgames. As a result, we confirmed that the entire relation among agents is constructed by the agents＇ changing partial relations and that the relations dynamically change.

The typical Critical Path Method (CPM) leaves it to the construction managers to overcome two problems in developing networks. First, the construction manager needs to prepare information on the type of activities and their precedence relations in order to develop a network schedule. Second, he or she can include space information into the network schedule such as the locations where the activities take place, only with difficulty. These two problems make it difficult for an inexperienced person to create a network. The purpose of this paper is to provide construction managers with set equations of creating a network schedule for multiunit projects. A space-resource combined network creation are presented in this paper, which includes equations for generating a list of required activities, their precedence relations, and information on their location. Information on the space (location) and the resource is the required data for this method. Based on this information, this method divides a project into a number of activities so that each activity contains the information on the location where the activity takes place and the principal resource required for that activity. Precedence relations are then obtained from the sequence of space and resource. This method has the potential to reduce human efforts in scheduling activities.

Acute myocardial infarction (AMI) is one of the three emergency diseases that require urgent diagnosis and treatment in the golden hour. It is important to identify the status of the coronary artery in AMI due to the nature of disease. Therefore, multi-modal medical images, which can effectively show the status of the coronary artery, have been widely used to diagnose AMI. However, the legacy system has provided multi-modal medical images with flat and unstructured data. It has a lack of semantic information between multi-modal images, which are distributed and stored individually. If we can see the status of the coronary artery all at once by integrating the core information extracted from multi-modal medical images, the time for diagnosis and treatment will be reduced. In this paper, we analyze semantic relations between multi-modal medical images based on coronary anatomy for AMI. First, we selected a coronary arteriogram, coronary angiography, and echocardiography as the representative medical images for AMI and extracted semantic features from them, respectively. We then analyzed the semantic relations between them and defined the convergence data model for AMI. As a result, we show that the data model can present core information from multi-modal medical images and enable to diagnose through the united view of AMI intuitively.
