This survey was conducted with crewmen on large purse seines in order to increase satisfaction of crewmen. The degree of fulfillment of internal marketing on crewmen (internal communication, empowerment, welfare benefits, management support, and reward system), satisfaction of crewmen, turnover intention, recommendation intention and need for achievement were examined. 200 surveys were distributed and 150 surveys were returned, among which insincere responses were excluded to analyze 146 responses. The results are as follows. First, factors of internal marketing that influence satisfaction of crewmen include empowerment, welfare benefits, and reward system. Second, turnover intention was reduced and recommendation intention was increased with increasing satisfaction of crewmen. Third, while need for achievement moderated the relationship between satisfaction of crewmen and turnover intention, it did not moderate the relationship between satisfaction of crewmen and recommendation intention. In other words, stronger need of crewmen for achievement causes greater negative(-) effect of crewmen's satisfaction on turnover intention.

Fluoride (F), over a narrow concentration range, increases bone formation. Aluminum (Ai) too is biphasic in its action on bone, being mitogenic at very low levels and inhibitory at higher levels. Both F and Al are present in finished drinking water where the chemical interaction of these two agents is well characterized. F and AI, given individually, accumulate preferentially in bone. In addition. in vivo studies have shown that F causes the co-accumulation of Al in bone. Thus, it was necessary to determine the interactive effect of these two agents on bone mitogenesis. Calvaria were obtained from neonatal CD-1 mice and cultured with various concentrations of F (0.05~19 ppm) as NaF, Al (2 ppb~2 ppm) as $AlCl_3$ , or F and Al for 3 days at $37^{\circ}C$ on a rotating roller drum. Alkaline phosphatase activity in calvaria and $\beta$-glucuronidase activity in culture medium were determined as a measures of bone turnover. Alkaline phosphatase activity in calvaria was significantly increased by F (0.05~2 ppm) treatment and $\beta$-glucuronidase activity was slightly increased in the culture medium of calvaria treated with 0.3 ppm Al. The combination of 19 ppm F and 0.3 ppm Al increased alkaline phosphatase activity in calvaria, but did not affect $\beta$-glucuronidase activity, suggesting the interactive effect of fluoride and aluminum on bone turnover.

Employee turnover is one of the most important challenges facing modern organizations. It causes job experiences and skills such as distinguished faculty members in universities, rare-specialized doctors, innovative engineers, and senior administrators. HR analytics has enhanced the area of data analytics to an extent that institutions can figure out their employees' characteristics; where inaccuracy leads to incorrect decision making. This paper aims to develop a novel model that can help decision-makers to classify the problem of Employee Turnover. By using feature selection methods: Information Gain and Chi-Square, the most important four features have been extracted from the dataset. These features are over time, job level, salary, and years in the organization. As one of the important results of this research, these features should be planned carefully to keep organizations their employees as valuable assets. The proposed model based on machine learning algorithms. Classification algorithms were used to implement the model such as Decision Tree, SVM, Random Frost, Neuronal Network, and Naive Bayes. The model was trained and tested by using a dataset that consists of 1470 records and 25 features. To develop the research model, many experiments had been conducted to find the best one. Based on implementation results, the Neural Network algorithm is selected as the best one with an Accuracy of 84 percents and AUC (ROC) 74 percents. By validation mechanism, the model is acceptable and reliable to help origination decision-makers to manage their employees in a good manner.

In 2008 the total estimated failure costs in the Netherlands was estimated to be 11.4% of the industry's turnover compared to 7.7% seven years earlier. Failure costs can be the consequence of rework as a result of failure to conform to the product requirements and specifications or due to inefficient processes and bad management practices. Many construction companies however are unaware of the exact nature of these costs, their root causes or how to control them. This paper describes work carried out in the Netherlands to identify the different types of failure costs in construction and their root causes. The research described builds on previous findings by another research institution and expands it to include information collected from project cases and a survey of a number of project managers in the construction industry. The paper describes the analysis of the results from cases and the survey to identify the root causes of failure costs. Research shows, for example, that many failure costs are related to the client taking late decisions and making changes to the project requirements.

This study was conducted to identify the job stress factors of school foodservice employees and to examine the relationship between job stress and turnover intention through path analysis. Data was collected using a survey of 432 school foodservice employees in elementary and secondary schools in Masan, Kyungsangnam-do. All of the participants were female, and 165(52.9%) were over the age of 45' Additionally, 310(99.4%) of the respondents were married, while 287(92.0%) had less than a high school level of education. Furthermore, 271(86.9%) of the respondents were cooks. Overall, 107(34.3%) of the respondents had worked in the food industry for less than $5{\sim}10$ years. In addition, 208 (66.7%) respondents answered that they had 'never' changed jobs. Among job characteristics that causes job stress, job posture was the primary stress factor, followed by heavy work load and job condition. Job stress was found to be significantly correlated with turnover intention. Additionally, job position was the only moderating variable that was found to be correlated with job characteristics and job stress. Finally, the moderating variables influencing the effects of job stress on turnover intention were identified as performance confidence, job career, and job position. The results of this study will be useful for future studies conducted to evaluate the development of job environments and performance to minimize turnover and job inefficiency as a result of job stress.

외형적으로 화려하고 인기직종으로 보이는 광고모델이지만 이면에는 많은 광고모델들이 직업에 적응하지 못하고 비교적 단기간에 이직하고 있다. 이는 광고모델 에이젠시의 업무에 상당한 차질을 초래하고 그 신뢰성에 부정적 영향을 주며 매출감소로 이어지고 있다. 이에 본 연구에서는 광고모델의 전문직업적 정체성, 감정노동, 역할갈등이 이직의도에 미치는 영향을 알아보고 또한 전문직업적 정체성, 감정노동, 역할갈등과 이직의도의 관계에서 신뢰성과 매력성 그리고 윤리적환경의 조절효과를 분석하여 광고모델의 이직의도에 대한 개선책을 제시하고자 하였다. 연구결과에 따르면 역할갈등, 감정노동, 전문직업적 정체성의 순서로 광고모델의 이직의도에 영향을 미치는 것으로 나타났다. 또한 위계적 회귀분석을 사용하여 이들 독립변수들과 이직의도간의 관계에 신뢰성, 매력성, 윤리적환경을 투입하여 조절효과를 검증한 결과 신뢰성은 감정노동이 이직의도에 미치는 부정적 영향을 조절하며, 윤리적환경은 전문직업적 정체성이 낮을 경우 이직의도에 미치는 부정적 영향을 조절하는 요인으로 나타났다. 이러한 결과는 감정노동자인 광고모델에게 자기신뢰가 갖는 중요성을 부각시키고 광고모델이 태어나는 것이 아니라 전문적이고 체계적이며 바람직한 직업 환경에 의해 만들어짐을 의미한다 하겠다.

During the last two decades the idea that central bank independence and transparency helps to maintain price stability, became popular among economists and central bankers. Many countries' governments give their monetary authorities higher independence and transparency to achieve the price stability goal. However, emerging countries such as Kazakhstan, suffer from high inflation. This inflation occurs largely due to a low level of independence and transparency of central banks. This research project measures the current level of independence and transparency of central bank of Kazakhstan. Indices were used to measure central bank independence and transparency. Central bank independence was measured by two types of indices: based on central bank laws (legal independence) and based on central banks governor's turnover (TOR). Developing countries have a weak legal framework, implying that a legal independence index cannot be appropriate to use as a measures of actual independence. Therefore, by paying attention to the other two indices, we can say that the central bank of Kazakhstan has a low level of independence and transparency. This, in turn, can be one of the causes of high inflation in Kazakhstan.

Nurses are critical human resources for the hospitals. However, in Korean hospitals, human resource management practices for nurses are not well established, and nurses' turnover rates are very high. Although the causes and tasks for shortage of nurses are analyzed, suggestions for the specific ways of HRM management practices for hospital managers are rare. In this article, the management challenges for nurses are discussed, and high commitment human resources management model for nurses are suggested. And future research directions and topics are suggested.
