  • Incorporation of individual learning and forgetting behaviors within worker-task assignment models produces a mixed integer nonlinear program (MINLP) problem, which is difficult to solve as a NP hard due to its nonlinearity in the objective function. Previous studies commonly assume homogeneity among workers in workforce scheduling that takes account of learning and forgetting characteristics. This paper expands previous researches by considering heterogeneous individual learning/forgetting, and investigates the impact of worker heterogeneity in initial expertise, steady-state productivity, learning and forgetting on system performance to assist manager's decision-making in worker-task assignments without tackling complex MINLP models. In order to understand the performance implications of workforce heterogeneity, this paper examines analytically how heterogeneity in each of the four parameters of the exponential learning and forgetting (L/F) model affects system performance in three cases : consecutive assignments with no break, n breaks of s-length each, and total b break-periods occurred over T periods. The study presents the direction of change in worker performance under different assignment schedules as the variance in initial expertise, steady-state productivity, learning or forgetting increases. Thus, it implies whether having more heterogenous workforce in terms of each of four parameters in the L/F model is desired or not in different schedules from the perspective of system productivity measurement.

  • Gender equality has been expected to realize fully in the process of globalization. According to neo-liberal, which views globalization as a rational development, irrational discrimination by culture will disappear. But some feminists criticize globalization as a patriarchal phenomenon. So in this paper, the extent to which women in Korea have achieved equality with men in the workforce is assessed through an examination of the gender gap during 1993-2003. As the result, it was found that women had still lower status than men in spite of laws established to promote gender equality. Then to explore the direction for eliminating the patriarchal gaps, women in traditional Korea were reviewed. Traditionally women were oppressed by the practice of Naeoe differentiating between women and men. But on the other hand it made women to have equal status with men by maintaining their own productive area. So it was suggested that differentiation should be considered as a source of power to be adopted into women's activitism such as NGOs or international women' movement to achieve full equality in inequitable globalization.

  • According to the trend of increasingly sophisticated cyber threats, the need for technology research that can be applied to cyber security personnel management and training systems is constantly being raised not only overseas but also in Korea. Previously, the US and UK have already recognized the need and have been steadily conducting related research from the past. In the United States, by encouraging applications based on related research (NICE Cybersecurity Workforce Framework) and disclosing successful use cases to the outside, it is laying the groundwork for profiling cyber security experts. However in Korea, research on cyber security expert training and profiling is insufficient compared to other countries. Therefore, in this study, in order to create a system suitable for the domestic situation, research and analysis of cases in the United States and the United Kingdom were conducted over the past few years, and based on this, a prototype was produced for the study of profiling technology for domestic cyber security experts.

  • Purposes: This study aimed to identify the relationships among personal and organizational communication skills, occupational stress, and patient safety activity levels of two nursing workforce groups (nurses and nursing assistants) who provide integrated nursing care services. Methodology: The study design is a cross-sectional study. Seventy-one nurses and forty-three nursing assistants working in the integrated nursing care service wards participated in this study. The data were collected using a self-reported questionnaire from June to July 2021. The relationships among the variables were analyzed using the Pearson correlation coefficient. Findings: Nurses' personal communication skills (r=.294, p=.013), organizational communication skills (r=.408, p<.001), and occupational stress (r=.243, p=.041) were associated with their patient safety activities. However, nursing assistants' personal communication skills, organizational communication, and occupational stress were not correlated with their patient safety activities. Practical Implication: Patient safety activities of nurses were related to their communication skills and occupational stress, but nurse assistants were not. Therefore, nurses should encourage nursing assistants to responsibly engage in patient safety activities and supervise their works appropriately to achieve high-quality care.

  • The United Arab Emirates (UAE) has experienced tremendous economic and industrial growth in the petroleum, airline, maritime and construction sectors, especially since the discovery of oil reserves. Mass recruitment of low skilled or unskilled laborers from less-developed countries has been utilized to satisfy the manpower demands of these fast paced industrial developments. Such workforce recruitment has created an unusual populace demographic, with the total UAE population estimated at 8.3 million, composed of 950,000 Emiratis, with the remainder being multinational expatriate workers, with varying educational qualifications, work experience, religious beliefs, cultural practices, and native languages. These unique characteristics pose a challenge for health and safety professionals tasked with ensuring the UAE workforce adheres to specific occupational health and safety procedures. The paper discusses two case studies that employ a novel multimedia approach to raising health and safety awareness among a multinational workforce.

  • The turnover rate of information security professionals in Korea is over 10% and turnover into non-information security fields accounts for over 50% of all the turnovers [1]. It is not only important to recruit a new quality workforce, but also to make the current workforce perform satisfactorily, to improve their performance, and eventually to attain information security objectives. This study proposes a Markov chain model for the turnover process of information security professionals and forecasts the job duty composition of information security professionals. The results of this study can be applied to secure the justification of government policies for the promotion of information security professionals.

  • Purpose - The purpose of this study is to examine the current trends of women in management fields from an Australian perspective. With the increase of women in the workforce, this will prove to be a valuable study. Research design, data, and methodology - This paper observed past research on women in management in Australia and defined some factors on their characteristics. Comparisons between the unique characteristics of women in management in Australia compared to those in Asia or other Western countries were evaluated. Results - Our results have showed that there are an increasing number of women in the workforce in management areas in Australia, and they are steadily rising. The gradual shift of perception in society on women entering the workplace and working will continue to have a lasting effect on the number of women in careers of management. Conclusions - The perception of women being at-home moms and men working has begun to shift in the current era. With this change evident in many countries around the world, other countries will also be able to include more women into the workplace. Raising awareness of the issues women face in the management world will be beneficial for aiding future women leaders.

  • This study has been carried out to provide data for the workforce by analyzing personnel status of medical device manufacturers, level of difficulty in securing human resource, reason for difficulty in securing human resource, resignation rate, and recruitment methods. Results, medical device manufacturers are required overseas sales personnel responsible for international certification and exported, regardless of the production item. And the company is located in the metropolitan area did not facilitate a secure workforce. Medical device manufacturers have difficulties in securing personnel, regardless of the employees and sales. In particular, Class 3 production company was more difficult. The reason that it is difficult to secure the human resources is attributable to the poor working conditions of the private companies and there is a few possible employees equipped with the job competency demanded by corporate entities. With respect to the analysis on the retirement rate, the larger the company scale and the more the employee number, more difficulty is experienced in the human resource management. Therefore, for any medical device manufacturers with large organization scale, it would be critical to introduce appropriate human resource management program.
