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.

This study concerns possible measures to prevent separatists' terrorist acts against overseas Korean businessmen. Of late, many Korean enterprises are helping a number of foreign countries develop their economy, by building factories and manning regional offices in those countries. But recent development of terrorism especially against Korean businessmen is alarming. This report discusses the need for Korean enterprises heading overseas to prepare themselves with awareness of terrorism and possible protective measures against it, besides their routine pursuance of profits; and for the government and prospective enterprises to refrain from investing in those countries having active separatist movements. If an investment has become inevitable, a careful survey of the region in conflict should be conducted and self-protective measures should be put in place through security information exchange, emergency coordination and training of personnel, etc. This study will first review the past terrorist incidents involving employees of overseas Korean enterprises, and then will focuss on seeking effective measures on the basis of the reported incidents. In carrying out the study, related literature from both home and abroad have been used along with the preliminary materials reported and known on the Internet from recent incidents. 1. The separatist movements of minority groups Lately, minority separatist groups are increasingly resorting to terrorism to draw international attention with the political aim of gaining extended self rule or independence. 2. The state of terrorism against overseas Korean enterprises and Koreans Korean enterprises are now operating businesses, and having their own personnel stationed, in 85 countries including those in South East Asia and Middle East regions. In Sri Lanka, where a Korean enterprise recently became a target of terrorist bombing, there are 75 business firms from Korea and some 700 Korean employees are stationed as of August 1996. A total of 19 different terrorist incidents have taken place against Koreans abroad since 1990. 3. Terrorism preventive measures Terrorism preventive measures are discussed in two ways: measures by the government and by the enterprises. ${\blacktriangleleft}$ Measures by the government - Possible measures at governmental level can include collection and dissemination of terrorist activity information. Emphasis should be given to the information on North Korean activities in particular. ${\blacktriangleleft}$ Measures by individual enterprises - Organizational security plan must be established by individual enterprises and there should also be an increase of security budget. A reason for reluctant effort toward positive security plan is the perception that the security budget is not immediately linked to an increment of profit gain. Ensuring safety for overseas personnel is a fundamental obligation of an enterprise. Consultation and information exchange on security plan, and an emergency support system at a threat to security must be sought after and implemented. 4. Conclusion Today's terrorism varies widely depending on reasons and causes, and its means has become increasingly informationalized and scientific as well while its method is becoming more clandestine and violent. Terrorist organizations are increasingly aiming at enterprises for acquisition of budgets needed for their activities. Korean enterprises have extended their business realm to foreign countries since 1970, exposing themselves to terrorism. Enterprises and their employees, therefore, should establish their own security measures on the one hand while the government must provide general measures, on the other, for the protection of the life and property of Korean residents abroad from terrorist attacks. In this regard, set-up of a counter terrorist organization that coordinates the efforts of government authorities in various levels in planning and executing counter terrorist measures is desired. Since 1965, when the hostile North Korea began to step up its terrorist activities against South Koreans, there have been 7 different occasions of assassination attempt on South Korean presidents and some 500 cases of various kidnappings and attempted kidnappings. North Korea, nervous over the continued economic growth and social stabilization of South Korea, is now concentrating its efforts in the destruction and deterioration of the national power of South Korea for its earlier realization of reunification by force. The possibility of North Korean terrorism can be divided into external terrorist acts and internal terrorist acts depending on the nationality of the terrorists it uses. The external terrorist acts include those committed directly by North Korean agents in South Korea and abroad and those committed by dissident Koreans, hired Korean residents, or international professionals or independent international terrorists bought or instigated by North Korea. To protect the life and property of Korean enterprises and their employees abroad from the threat of terrorism, the government's administrative support and the organizational efforts of enterprises should necessarily be directed toward the planning of proper security measures and training of employees. Also, proper actions should be taken against possible terrorist acts toward Korean business employees abroad as long as there are ongoing hostilities from minority groups against their governments.

We, in Korea, have over two hundred hypermarkets and the number is continuously increasing. We drop into a hypermarket for merchandise, which is an integral part of our life style. So, we should consider safety for employees as well as customers because hundreds of thousands of people use the hypermarket every day. In addition to this consideration, the government should also be a political support relating to accidents that occur in the hypermarket because security and safety matters are important to all of us. But even now, Our security conditions do not match our ideal goal and we take countermeasures after accident or loss. This is a result of not having a security management expert coupled with a chief executive officer that has no idea about security awareness and loss prevention. In addition, we do not have specific laws to address these matters. We also lack reasonable ideas to prevent accident and loss. Now is the right time to revamp the laws and ordinances to improve the quality of civilian life. Prevention of accidents is a needed investment for all security personnel. The best solution for businesses is prevention of accidents. This will increase profits and cost-effectiveness as well as increase customer satisfaction. The company should form a security management department for comprehensive protection of assets. The goal of security management employees should be productive and effective security management. Every employee should have responsibility in mind to prevent accidents in his or her work. In addition, The company should have a systematic organization in place and regular training sessions. The most effective security management comes from cooperation of all members. In the 21st century, we pursue a high standard of living which is a result of our cooperation against any accident and loss. Sennewald says The value of security is better measure by what does not happen rather than what does.

Purpose: The purpose of this study is to determine the influence of hospital employees' perceptions and performance expectations on IT technologies introduction and intention to use in the Fourth Industrial Revolution. Methodology: A survey was conducted on 524 employees at 42 hospitals. Pearson's correlation analysis, regression analysis, Sobel test, and structural equation were used for the analysis. Findings: The factors of technical situation (complexity, compatibility, technical readiness, and security concerns), those of environmental situation (competitive pressure and regulatory support), and organizational situation (top management support and costs) have influenced on the recognition of employees in the hospital and the performance expectations. IT technology introduction and use intention have been influenced by technical situation, organizational situation, and environmental situation in order. But security concerns and cost factors have not statistically affected. In addition, due to the perception and performance expectations of hospital employee who have a role in mediating the introduction and use intention of IT technology, the greater the perception and performance expectations of hospital employees, the higher the intention of introduction and usage of IT technology. Practical Implications: Rather than considering the position of external customers and the position of competitive hospitals, more attention is required for the perception and performance expectations of the internal members.

Being able to survive during the Covid19 pandemic is a big task for a company, as such, empowerment of employees is a must. The sample in this study was 300 employees who worked in Spas throughout Bali. The sampling technique was purposive sampling. Data analysis was using SEM and SMARTS as data processing. The results showed that green communication, namely communication that occurs between employees, superiors, and the environment, has a very good influence on the sustainability of employee performance. To become green management, a green organizational commitment that cares about the safety of employee health and the environment is an important factor as motivation in green dedication or positive employee productivity, but communication between work actors and justice is also a motivating factor. Work safety and job security for employees empower employees (which is a green line), especially for freelance work organizations so that further research in subsequent studies can make samples in a more varied industrial sector.

Negative consequences incurred from employees' non-work-related computing (NWRC) have been one of the security-related issues in information intensive organizations. While most studies have focused on the factors that motivate employees to engage in NWRC, this study examines the mediating effect of moral beliefs on the relationship between sanctions and NWRC using a moral beliefs-based model. The research model posits that the formal (i.e., punishment severity and detection certainty) and informal sanctions (subjective norms and descriptive norms) enhance employees' moral beliefs against NWRC intention. From a cross-sectional scenario-based survey involving 176 employees working at banks in Mongolia, our results indicate that moral beliefs fully mediate the relationship between detection certainty/subjective norms and NWRC intention and act as a partial mediator in the relationship between descriptive norms and NWRC. The findings from this study present empirical evidence that both informal and formal sanctions could be an effective deterrent for NWRC intention through employees' moral beliefs.

The increasing number of crimes in rapidly changing modern society is enhancing people's desire for safety. As of 2008, 2,900 private security businesses with 133,000 employees operated in the private security industry which emerged in response to growing demands from society and people. Of the employees, bodyguards (hereinafter referred to as "private security guard") accounted for about 10% or 13,000. Most private security guards were suffering from various occupational diseases. Especially as they needed to guard their clients many hours a day and worked in a standing position for a long time, private security guards often complained of low back pain. Under the pain, they were hardly expected to perform their tasks efficiently. There are several causes of low back pain. The most prevalent cause is muscle weakness and imbalance around low back. Especially because private security work often requires security guards to maintain a standing position for a long time, many of them are suffering from low back pain. This study pursued the following purposes. First, it tried to identify the pathogenesis of low back pain caused by muscle weakness and imbalance around low back. Second, it tried to provide private security guards, who can hardly have personal time at work, with an easy method to prevent and manage low back pain any time by researching an effective therapy for low back pain caused by muscle weakness and imbalance around low back.
