In this paper, we propose an algorithm that recognizes human activity patterns using the human body's joints and the information of the joints. The proposed method extracts the object from inputted video, automatically extracts joints using the ratio of the human body, applies block-matching algorithm for each joint and gets the motion information of joints. The proposed method uses the joints to move, the directional vector of motions of joints, and the sign to represent the increase or decrease of x and y coordinates of joints as basic parameters for human recognition of activity. The proposed method was tested for 8 human activities of inputted video from a web camera and had the good result for the ration of recognition of the human activities.

Elderly welfare practitioners study on job performance systems and information security management though important information, including personal information, social services for the elderly extent of protection is insufficient. The elder welfare institution engaged in information security of whether the research was conducted to enhance information security capabilities against How does affect the information security acts as a parameter. The empirical research was conducted by latent mean analysis by gender of workers. As a result of the study, there were differences among the groups according to gender in relation to information security awareness, information security capacity enhancement, and information security behavior. There were gender differences in information security behavior. It has been found that the strengthening of information security has an important influence on information security behavior.

The purpose of this study is to empirically examine a behavior improvement of unethical information sharing through the ethics program in organization. An unethical behavior of information sharing on organization members is to be get to private interests through divulgence of company's confidential information. An unethical information-sharing of individual is the opportunist and selfish behavior for an expansion of social capital and shows a negative ripple effect in organization. When conducting the research methods, the analysis order performs the cluster, discriminant, t-test and multiple regressions. According to the study, There are differences the behavior of unethical information sharing between opportunist and non-opportunist. The opportunist member for unethical behavior improvement required the program operation both value and compliance oriented program. Non-opportunist member required only the value-oriented program. The upcoming research needs to explore both ethics program's frequency and action of a punished person.

The purpose of this study was to analyze whether tourism information is influenced by information collected through smartphone. Especially, this study investigated the behavior of tourists visiting Jeju by using the information of smartphone, and analyzed the collected data to find out the marketing implications for Jeju tourist. This study analyzed how smartphone information influenced individual 's behavior after distributing direct questionnaires to tourists. The data of total 230 tourists who visited the tour in April, 2017 were collected and analyzed. As a result of the analysis, it was statistically verified that the information of the smartphone affected the behavior of the tourist. Though this analysis, this study can contribute to the establishment of diverse management strategies using the understanding of the behavior of tourists and marketing implications by investigating the effect of smartphone information on the behavior of tourists.

호텔기업은 최고의 서비스를 주고받는 산업으로 다른 기업과의 비교우위를 위하여 우수한 인력개발을 통해 조직의 효율성을 확보하는 전략에 초점을 맞추어 왔다. 따라서 본 연구는 호텔종사원을 연구대상으로 선정하여 첫째, 관계갈등이 조직시민행동에 영향을 미칠 것이다, 둘째, 과업갈등이 조직시민 행동에 영향을 미칠 것이다. 셋째, 관계갈등과 조직시민행동과의 관계, 과업갈등과 조직시민행동과의 관계에서 셀프리더십의 조절을 살펴보았다. 자료 수집을 위한 설문조사는 서울 경기도 지역의 특급호텔 종사원을 대상으로 400명에게 설문을 실시하였다. 분석결과를 예측해보면 첫째, 관계갈등은 조직시민행동에 유의미한 관계를 미칠 것으로, 둘째 과업갈등은 조직시민행동에 유의미한 관계를 미칠 것으로, 셋째, 셀프리더십은 관계갈등과 조직시민행동간의 관계에서 조절변수의 역할을 넷째, 셀프리더십은 과업갈등과 조직시민행동에 조절효과를 미칠 것으로 판단되어 진다. 조직시민행동의 예측변인으로서 관계갈등과 과업갈등에 대하여 탐색적인 수준에서 연구가 이루어졌음에도 관계갈등과 조직시민행동 그리고 셀프리더십의 상호작용을 다룬 연구가 이루어진 것에 의미가 있다. 또한 관계갈등과 조직시민행동의 관계를 조절하고 과업갈등과 조직시민행동과의 관계를 조절할 것으로 예측되어지는데 이는 후속연구의 바탕이 될 수 있을 것이다. 이런 연구결과를 바탕으로 조직의 관리자는 관계갈등과 과업갈등을 최소화 하고 조직시민행동을 높일 수 있는 방안에 대한 다양한 자기개발 및 프로그램을 개발하고 종사원에게 제공하여 건실한 조직문화를 이루어야 하겠다.

This research attempts to identify how members of an online community collaboratively engaged with particular social information behaviors and accomplished a defined collective action. While responding to the Sewol Ferry tragedy, MissyUSA members quickly communicated and mobilized a collective action, a full-page ad campaign in The New York Times. As a follow up study, this secondary analysis quantitatively analyzes the primary data from a previous study to explore potential relationships or underlying factors among the various identified information behaviors. In this study, nineteen of the previously identified information behaviors were analyzed using exploratory factor analysis, yielding a total of eight factors. The two major factors of shared representation/collective identification and mobilizing resources verified the findings of the previous study and are in line with the findings typical of political science. The three factors of collaborative decision-making, reaction to tension, and brainstorming were factors that maximized communication and mobilization online, without any face-to-face communication or physical organization. Three emergent factors of outburst of dissent, boycott, and planning explained how members used negative emotions of anger, referential information for boycott, and incubated next collective actions. Through exploratory factor analysis, this study verifies and expands on the findings of the previous study by identifying several emergent factors that relate to the collaborative information behaviors of an online community engaged in a collective action.

인터넷이 생활의 한 부분이 되면서 인터넷 사용자가 급증함에 따라 각종 사이버 범죄의 발생 건수 역시 크게 증가하고 있다 이러한 각종 사이버 범죄에 대응함에 있어서 가장 심각한 문제 중의 하나는 해커가 어떤 기술을 이용하여, 어떠한 방식으로 해킹을 진행하는지에 대한 정보가 매우 부족하다는 것이다. 현재 해커들은 해킹에 성공하기 위해 고도의 해킹 기법과 새로운 취약점을 이용하고 있는 반면, 해킹 방지를 위해 사용되고 있는 보안 강화 시스템들은 새로운 방식을 이용하는 해킹 시도를 효율적으로 방어하지 못하고 있는 것이 현실이다. 이와 같은 문제점을 해결하기 위해 제안된 것이 해커의 행동 양식에 대한 정보를 얻기 위한 침입유도 시스템(Honeypot)이다. 그러나 기존의 침입유도 시스템은 해커의 행동 양식 파악에 전문적인 기술이 필요하여 실시간 정보분석이 용이하지 못했다. 이에 본 논문에서는 해커의 행동양식을 실시간으로 파악하고 분석하는 허니넷(Honeynet) 형태의 침입자 행동양식 파악 시스템(Honeypot)을 설계하고 개발하였다.

As the reduction of information exposure threats by organization insiders contributes to achieving information security(IS) goals, organizations are establishing strict IS policies applicable to insiders and increasing investment in IS systems. However, since IS incidents cause damage to an organization even by malicious information exposure by one person, psychological support for strengthening IS compliance behavior by insiders. This study aims to confirm how the uncertain organizational environment related to IS affects individual IS-related behavior. We surveyed insiders of organizations operating IS policies and tested the hypothesis using 440 samples. As a result, IS technology and communication uncertainty reduced IS voice behavior through IS prospective anxiety, and individuals' susceptibility to information influence moderated the relationship between IS technology, communication, and prospective anxiety and IS voice behavior. Our results suggest the necessity and direction of supplementing the uncertain IS environment in practice.

Globally, information protection of organization has become an essential management factor, and organizations continue to invest high-level resources for information security. Security threats from insiders are not decreasing. The purpose of this study is to present the antecedence factors to mitigate the role conflict that is the cause of the security avoid behavior. For the study, a survey was conducted for employees of organizations with information security policies, and structural equation modeling was conducted using a total of 383 samples for hypothesis verification. As a result of the analysis, role conflict increased avoid behavior, and goal difficulty, goal specificity, justice, and trust mitigated role conflict. In particular, justice influenced the reduction of role conflict and avoid behavior through trust. The implications were to present the causes and mitigation factors for avoid behavior of employee, and it is judged that it will help the organization to establish a security strategy.
