Social engineering attack means to get information of Social engineering attack means to get information of opponent without technical attack or to induce opponent to provide information directly. In particular, social engineering does not approach opponents through technical attacks, so it is difficult to prevent all attacks with high-tech security equipment. Each company plans employee education and social training as a countermeasure to prevent social engineering. However, it is difficult for a security officer to obtain a practical education(training) effect, and it is also difficult to measure it visually. Therefore, to measure the social engineering threat, we use the results of social engineering training result to calculate the risk by system asset and propose a attack graph based probability. The security officer uses the results of social engineering training to analyze the security threats by asset and suggests a framework for quick security response. Through the framework presented in this paper, we measure the qualitative social engineering threats, collect system asset information, and calculate the asset risk to generate probability based attack graphs. As a result, the security officer can graphically monitor the degree of vulnerability of the asset's authority system, asset information and preferences along with social engineering training results. It aims to make it practical for companies to utilize as a key indicator for establishing a systematic security strategy in the enterprise.

Evaluating infrastructure's impact on social equity is an emerging area of research in transportation construction engineering. Transportation agencies have been trying to include sustainable development. The three components of sustainable development are environmental protection, social equity, and economic development. Although social equity is one of the essential components of sustainable development, most transportation agencies do not consider this component. The research publications in this area are limited. The principal objective of this study is to synthesize existing studies related to the impact of transportation infrastructures on social equity. This study will also identify social equity indicators, the correlation between social equity and transportation infrastructures and their services, and the impact of transportation infrastructures' on social equity. In addition, this study will identify current issues of social equity and will provide some recommendations. This synthesis study revealed that transportation infrastructures impacted social equity in various ways. Some effects are positive, such as new job creation on the market. Other effects are adverse, such as diminishing socio-economic and environmental degradation. Studies also showed that the current practices evaluated infrastructures' impact on a case-by-case basis. The authors recommend adopting a multi-disciplinary holistic for assessing infrastructure's effects on social equity. The multi-disciplinary fields of study include civil engineers, construction engineers/managers, public policy researchers, environmentalists, and social scientists.

Recently, the Social Internet of Things (IoT), the follow-up of the IoT, has been studied to expand the existing IoT services, by integrating devices into the social network of people. In the Social IoT environment, humans, devices and digital contents are connected with social relationships, to guarantee the network navigability and establish levels of trustworthiness. However, this environment handles massive data, including social data of humans (e.g., profile, interest and relationship), profiles of IoT devices, and digital contents. Hence, users and service providers in the Social IoT are exposed to arbitrary data when searching for specific information. A study about the recommender system for the Social IoT environment is therefore needed, to provide the required information only. In this paper, we propose the Social correlation group based Recommender System (SRS). The SRS generates a target group, depending on the social correlation of the service requirement. To generate the target group, we have designed an architecture, and proposed a procedure of the SRS based on features of social interest similarity and principles of the Collaborative Filtering and the Content-based Recommender System. With simulation results of the target scenario, we present the possibility of the SRS to be adapted to various Social IoT services.

This research sought to investigate the relationships among self-leadership, social support and interpersonal competence of women engineering students. First, women undergraduate students' differences respecting self-leadership, social support and interpersonal competence were examined. Second, the relationships among self-leadership, social support and interpersonal competence were identified in terms of sub-factors of those three variables. Third, the effects of social support and interpersonal competence, as perceived by women undergraduate students, on self-leadership were explored. A total of 398 women undergraduate students from three universities in Korea responded to survey based on a three-variables scale. The findings were that, firstly, women engineering students scored lower in all of the three variables including self-leadership, social support and interpersonal competence, and that these major differences were statistically significant. Secondly, a positive correlation among self-leadership, social support and interpersonal competence was identified. Thirdly, it was determined that self-leadership was affected significantly by social support and interpersonal competence. The practical implications of these findings are discussed herein, with particular attention on education for promotion of self-leadership, social support and interpersonal competence.

In previous research of social dilemma, there is no extended game that the players can select one game out of some social dilemma games. We propose this kind of game as ＂Distributed Social Dilemma＂ In this game, each player tries to acquire the adaptive strategy throughout local interactions. We make use of GA as evolutionary operations. In this paper, our purpose is to examine how the game selection of players influences the evolution of cooperation in distributed social dilemma. In order to examine, we formulate distributed social dilemma by Game Theory and use agent-based simulation that each agent is regard as player

Recently, Social Commerce that provides customer with cheap deals is under the spotlight. The purpose of this study is to propose how to use social commerce on small restaurant business, which encompass almost a half of entire deals. We analyzed each element from the last transaction data of three social commerce company and survey obtained from the restaurant business. As a result, we can find that the purpose of promoting, the location of restaurant, whether is franchise or not, price and menu composition have an effect on sales of coupon. Based on these results, we proposed two step approaches to use the social commerce company. The first step is to decide whether social commerce is used or not and the second step is to define the detail content of deal including the social commerce company. We convinced that our proposed strategy is very helpful to the small restaurant which considers utilization of social commerce company.

Corporate Social Responsibility has become a hot issue for modern enterprises recently. Under this trend, companies have to focus on what they can do for society instead of on just making profits. This paper is to explore the relationship between ecological corporate social responsibility and organizational performance in the construction industry in Taiwan. 192 samples were collected from Taiwan's general contractors and analyzed using factor analysis, correlation analysis and path analysis. This study found: (1) in general, the contractors in Taiwan don't devote much to realizing ecological corporate social responsibility, and there is still much room for improvement; (2) the correlation analysis results indicated there are significant positive relationships between ecological corporate social responsibility and organizational performance; and (3) according to the path analysis results, a contractor can improve its business performance by improving its realization of corporate social responsibility.

With the exponential developments of social network, their fundamental role as a medium to spread information, ideas, and influence has gained importance. It can be expressed by the relationships and interactions within a group of individuals. Therefore, some models and researches from various domains have been in response to the influence maximization problem for the effects of "word of mouth" of new products. For example, in reality, more than two related social groups such as commercial companies and service providers exist within the same market issue. Under such a scenario, they called social adversaries competitively try to occupy their market influence against each other. To address the influence maximization (IM) problem between them, we propose a novel IM problem for social adversarial players (IM-SA) which are exploiting the social network attributes to infer the unknown adversary's network configuration. We sophisticatedly define mathematical closed form to demonstrate that the proposed scheme can have a near-optimal solution for a player.

Infrastructure development as national project suffers from social conflict which is one of main risk to be managed. Social conflicts have a negative impact on not only the social integration but also the national economy as they require enormous social costs to be solved. Against this backdrop, this study analyzes social conflict using articles published by online news media based on web-crawling and natural language processing (NLP) techniques. As an illustrative case, the Jeju Naval Base (JNB) project which is one of representative conflict case in South Korea is analyzed. Total of 21,788 articles and representative keywords are identified annually. Additionally, comparative analysis is conducted between the extracted keywords and actual events occurred during the project. The authors explain actual events in the JNB project based on the extracted words by the year. This study contributes to analyze social conflict and to extract meaningful information from unstructured data.
