It is getting more intensified with the competition among participating companies for global market share in major industrial fields. The situation is accelerating especially within the top 5 market share, and these include electric vehicles, semiconductors, chemicals, and shipbuilding industries. The key to the advantage over the competition within a strategic group is which company leads the innovation in the field. On-the-ground innovation refers to job-based innovation. This paper aims to analyze job unit innovation in the structure of empowerment, LMX, and job crafting. Existing studies on job crafting have suggested a causal structure based on job design in the traditional sense, and there are not many scholars who study the causal structure using a job situational model. Therefore, this paper takes an approach from the perspective of the job situation. As a result of the study, LMX showed a moderating effect on the relationship between autonomy provision and job crafting. While, in the relationship between meaing-giving and cognitive crafting, there is no significant moderating effect shown on the relationship between autonomy provision and cognitive crafting. Therefore, the results of the analysis in this study suggest that the meaning of jobs and participation in decision-making should be managed in an integrated way in structural and design areas, not just qualitative factors such as empowerment and leadership.

본 연구는 한국인이 보이는 욕구-현실 충돌에서 나타나는 극복 노력 현상(불굴의 의지)을 한국인의 문화적 특성으로 설명하고자 하였다. 구체적으로 자신의 욕구와 현실 간의 충돌이 발생한 상황에서 개인의 주체성 정도에 따라 그 상황을 대하는 행동 양식이 달라지는지를 살펴보았다. 이를 위해 총 217명의 참여자가 온라인 실험에 참여하였고, 최종적으로 156명의 데이터가 분석되었다. 참여자는 주체성 척도에 응답한 뒤, 상충적 요소가 존재하는 의사결정 시나리오에 노출되었다. 시나리오는 집 구매와 결혼식장 계약 시나리오였고, 각 시나리오에서는 중요하게 여겨지는 두 개의 가치가 시장에서 서로 상충되도록 설정되었다. 참여자는 해당 시나리오를 읽고 각 가치에 대해 스스로가 원하는 수준을 입력하였다. 그 뒤, 시나리오 속 대리인이 참여자가 원하는 수준의 후보지를 찾지 못한 상황을 접하게 된다. 이후, 참여자는 스스로 자신이 직접 나서 추가적인 노력을 할 의향에 대해 응답하였다. 연구 결과, 참여자의 주체성 정도는 추가적인 노력 정도에 정적인 관계를 나타냈다. 또한 현실 한계를 초과하여 원하는 수준(기대 불일치)의 정도는 주체성을 통제한 상태에서 추가적인 노력 정도에 대해 비선형(역 U형)의 영향력을 나타냈다. 나아가 주체성과 기대 불일치 간의 상호작용효과가 유의하였다. 구체적으로 주체성이 낮은 개인은 기대 불일치 정도와 종속변인 간의 관계가 유의하지 않았으나, 주체성이 높은 개인은 기대 불일치 정도와 종속변인 간의 비선형 관계가 유의하였다. 연구 결과를 바탕으로 욕구-현실 충돌 장면에서의 한국인의 심리적 특성(주체성)의 역할과 기능에 대해 논하였다.

In this paper, a method to classify insider threat activity is introduced. The internal threats help detecting anomalous activity in the procedure performed by the user in an organization. When an anomalous value deviating from the overall behavior is displayed, we consider it as an inside threat for classification as an inside intimidator. To solve the situation, Markov Chain Model is employed. The Markov Chain Model shows the next state value through an arbitrary variable affected by the previous event. Similarly, the current activity can also be predicted based on the previous activity for the insider threat activity. A method was studied where the change items for such state are defined by a transition probability, and classified as detection of anomaly of the inside threat through values for a probability variable. We use the properties of the Markov chains to list the behavior of the user over time and to classify which state they belong to. Sequential data sets were generated according to the influence of n occurrences of Markov attribute and classified by machine learning algorithm. In the experiment, only 15% of the Cert: insider threat dataset was applied, and the result was 97% accuracy except for NaiveBayes. As a result of our research, it was confirmed that the Markov Chain Model can classify insider threats and can be fully utilized for user behavior classification.

The main objective of this research is to develop a model to select the optimal input service level for a distribution center - multi branch inventory distribution system. With the continuous review policy, the distribution center places an order for specific order quantity to an outside supplier, and the order quantity is replenished after a certain lead time. Also, each branch places an order for particular order quantity to the distribution center to satisfy the customer demands, and receives the replenishment after a lead time. When an out of stock condition occurs during an order cycle, a backorder is placed to the upper level to fill the unfilled demands. With these situation, variable demand and variable lead time are used for better industrial practice. Further, actual lead times with a generic lead time distribution are used in developing the control model. Under the actual lead time model, the customer service measures actually attained for the distribution center and each branch are explained as the effective customer service measures. Thus, throughout the optimal control (using computer search procedures), we can select the optimal input service levels for the distribution center and each branch to attain the effective service level for each branch which is consistent with the goal level of service for each branch. At the same time, the entire distribution system keeps minimum inventories.

This study examined the gender differences' composition affecting poverty in Busan and possible strategies for overcoming poverty. It was found that there were both common and differentiating points regarding gender in poverty situations. Poverty stricken women, tended to be older and less educated than their male counterparts. In the case of men, they were more likely to have physical disabilities than women. There were more women compared to men when regarding divorce and separation due to the death of a spouse as contributing to poverty. Women estimated that it was much easier to overcome their poverty situation as they were younger and had more income. However, there were gender differences in regard to actual re-establishment. For men, education level was the most important variable for overcoming poverty while for women; the existence of a spouse was the important variable. These results suggest that a gender sensitive approach is necessary to address and find solutions to the poverty issue. Therefore, it is hoped that this study's findings may provide valuable information and support for changes to the welfare policy.
