The purpose of this study was to investigate the effects of female applicant's facial attractiveness and feminine-masculine clothing image on job performance evaluation and hiring decision. The research design of study consisted of 3(facial attractiveness high, middle, low)${\times}$2(feminine and masculine clothing image) factorial design. The subject consisted of 243 persons whose occupation were mid-sized companies' administrator in Gwangju and Seoul City. The data were analyzed by factor analysis, Duncan test, ANOVA, t-test. The results of this study were as follows. First, three factors emerged to account for the job performance evaluation. These factors were given the titles of task performance, cooperation and self-management factors. Second, applicant's facial attractiveness exerted significant positive effect on self-management and significant negative effect on cooperation. Third, applicant's facial attractiveness exerted significant effect on hiring decision. Finally, the interaction effect of female applicant's facial attractiveness and feminine-masculine clothing image on job performance evaluation and hiring decision were not significant.

Given a fixed production process and facility capacity, the ability to respond to market fluctuations in terms of changes in production, work force, and inventory is the major task of production management. The costs involved are primarily payroll (regular and overtime), inventory carrying, and hiring and firing. The magnitude of these costs is usually a significant portion of the operating costs of the firm and consequently a small percentage saving due to astute aggregate scheduling can mean substantial absolute saving. At least three demonstrably optimal techniques have been developed for solving this aggregate scheduling problem. These three optimal are apparently LDR, PPP, and SDR. By combining these three different approaches, another optimal solution was obtained by me. I call this CDR (Combined Decision Rule). This approach appears to be useful. This approach may be generalizable to aggregate scheduling involving a short term resources.

In this paper, the employment planning model is developed which is a decision-making model for determining the optimum employment level with respect to varying net manpower requirement for each planing period such that total cost in a planning horizon is minimized. It is constructed as a nonlinear programming model and a dynamic programming model on the basis of studies in the areas of production smoothing and manpower scheduling. Costs for a planning period are categorized into regular wage cost, hiring cost, and overtime cost. The first is a linear function. The other two cost functions are of quadratic nature. The planning horizon of this planning model is intermediate range (five years) for which a fair planning accuracy can be guaranteed. The model considers learning period for each job class. It is simple and an optimum solution can be easily obtained by direct search techniques.

Purpose In order for companies to continue to grow, they should properly manage human resources, which are the core of corporate competitiveness. Employee turnover means the loss of talent in the workforce. When an employee voluntarily leaves his or her company, it will lose hiring and training cost and lead to the withdrawal of key personnel and new costs to train a new employee. From an employee's viewpoint, moving to another company is also risky because it can be time consuming and costly. Therefore, in order to reduce the social and economic costs caused by employee turnover, it is necessary to accurately predict employee turnover intention, identify the factors affecting employee turnover, and manage them appropriately in the company. Design/methodology/approach Prior studies have mainly used logistic regression and decision trees, which have explanatory power but poor predictive accuracy. In order to develop a more accurate prediction model, XGBoost is proposed as the classification technique. Then, to compensate for the lack of explainability, SHAP, one of the XAI techniques, is applied. As a result, the prediction accuracy of the proposed model is improved compared to the conventional methods such as LOGIT and Decision Trees. By applying SHAP to the proposed model, the factors affecting the overall employee turnover intention as well as a specific sample's turnover intention are identified. Findings Experimental results show that the prediction accuracy of XGBoost is superior to that of logistic regression and decision trees. Using SHAP, we find that jobseeking, annuity, eng_test, comm_temp, seti_dev, seti_money, equl_ablt, and sati_safe significantly affect overall employee turnover intention. In addition, it is confirmed that the factors affecting an individual's turnover intention are more diverse. Our research findings imply that companies should adopt a personalized approach for each employee in order to effectively prevent his or her turnover.

The purpose of this study is to figure out the current condition of local governments (Si or Gun) to implement rural development policy in the face of the central government's drive for increasing devolution. Since late 1990s or early 2000s when scope of rural policy began to expand quantitatively, there has been considerable increase in rural residents' participation into community projects as a whole. Nevertheless, there exists regional differentiation in local governments' efforts to systematically support rural development projects (CRDP: Comprehensive Rural Development Programme) and community activities by setting up intermediary organizations or hiring rural development professionals in a public office. According to this survey on local government officials, regions that have made such efforts to support rural policy at a local level, show more advanced level of institutional capacity than other regions in local decision making process for CRDP, role of strategic rural developmental plans, vitality of community actors, etc. In the era of increasing devolution, these differences can be expected to result in diverging performances of each area in regionalized rural policy. The central government needs to introduce EU's LEADER-type rural development programmes to support community acitivities by various local actors and at the same time promote local governance building for rural policy, adopting institutional rewarding system such as rural planning contract.

'트로이 목마 프로그램 (Trojan-horse program)'이란 겉으로는 유용한 일을 하는 것처럼 보이지만 사용자 모르게 악성 행위를 하는 프로그램을 의미한다. 본 논문에서는 개발자의 첨부 자료에 의거하여 트로이 목마 프로그램을 감지할 수 있는 방법을 제안한다. 이 방법에서 코드는 개발자에 의해 자원 접근 정보를 가지는 첨부자료와 함께 배포되며 사용자는 첨부 자료를 통해 코드의 악성 여부를 1차 판단한다. 이 때 정상 코드로 판명되어 수행이 허가된 코드는 수행 중에 감시 시스템에 의해 자신의 첨부자료에 위배되지 않는 다는 것을 2차로 감시 받게 된다. 이로써 알려지지 않는다는 트로이 목마 프로그램의 감지가 가능함과 동시에 기존 감시 시스템 기법들에 비해 사용자 측의 정책 설정 및 판단 부담을 줄여주는 특징을 가진다. 본 논문에서는 제안된 방식을 형식 언어로 기술하고 그 안전성도 함께 보인다.

이 글은 1990년부터 진행된 미국의 인구센서스의 변화와 향후의 전망에 대해서 2000년의 경험과 2010년의 계획을 중심으로 논의한다. 먼저, 2000년 센서스의 준비과정에서 미국 과학원학술평의회 국가통계위원회가 작성한 2000년 센서스 개선안의 내용을 통계적 추정방법 도입, 응답률 개선방안, long form 개선방안, 소수민족 집계누락, 인구센서스 대체방안, 센서스 비실시 연도 소지역통계 확보방안, 센서스 프레임 정비 등으로 살펴보고, 1998년 대법원 판결 이후 2000년 센서스에서 통계적 추정방법을 이용한 미국판 One Number Census를 추진하지 못하게 된 경위를 검토한다. 다음은 2010년 인구센서스의 핵심적 특성의 하나인 long form과 short form의 분리, 곧 short form은 전통적 센서스, 곧 전수조사와 현장실사의 원칙을 준수하는 방식으로 그대로 두고, long form을 대체하여 순환센서스로 진행되는 American Community Survey에 대해서는 그 과정과 주요 특성을 검토한다. MAF/TIGER는 인구센서스의 집계과정에서 정확성을 향상 하고자 하는 또 하나의 특성으로, 이것은 2010년 센서스에서 모바일 컴퓨터를 도입하는 하이테크 센서스를 목표로 기획된 것이었다. 이 글은 미국 센서스에서 short form과 long form의 분리가 대법원 판결로 우연히 일어난 것이 아니라는 점을 강조하기는 하지만, 미국 센서스는 2008년 현재, 인구조사국의 모바일컴퓨터 개발실패로 60만 비정규직 조사원의 고용을 불가피하게 할 것으로 예상되며, 이로 말미암아 2010년 미국 센서스의 정확성에 대한 우려감이 증대하고 있음을 지적한다.

Modern organizations, both complicated and complex, operate in an economic climate of· turbulence and rapid change. And Today's healthcare environment is changing, driven by demographic, environmental. social, political and technological forces. In actual practice, the organization usually depend on several factors such as economic state of organization, managerial strategies, a synthesis of several theories that reflect individual biases, specific circumstances, and practical realities. These rapidly changing healthcare environment and professional nursing practice need a strategy for the organizational development and goal attainment. An understanding of organizational culture could help managers enhance or expand their management strategy, thus increasing the probability of their success in the organization. Organizational culture is an abstract, yet potent managerial concept. With roots in several disciplines, several perspectives and definitions of organizational culture have emerged. The concept of organizational culture has been rapidly introduced into the academic and organizational world, with the much attention to the excellent companies that have continued rapid grow th despite the overall world economic recession in the late of 1970s. Organizational culture is the combination of the symbols, language, assumptions, and behaviors that overtly manifest an organization's norm and values. It is the taken-for-granted and shared meanings people assign to their social surroundings that can have a profound effect on an organizaitonal decision making and performance. For attaining a organizational goal and developing organization, it is necessary to put emphasis on developing organizational culture. It has to set organizational culture well understood by its members as an instrument to achieve the organizational goals. Both Manager and staff can focus and act on the values identified. Also, managers will exhibit better decision making capabilities because they are guided by perception of the organizational values. Therefore, understanding of organizational culture could give a strategy for organizational development that assist hiring personnel, orienting new comers, facilitating organizational change and promoting learning and so on. But their is few study on nursing organizational culture in Korea. Moreover they have not had a clear definition of Korean nursing organizational culture. Therefore, it is necessary to lay down definition of Korean nursing organizational culture and fine out real factor of Korean nursing culture. For defining a definition of Korean nursing organizational culture, this study assessed several definitions of organizational culture, factors of culture, types of culture, and functions of culture through book review.
