In order to increase the productivity of the logistics center and transportation, we try to articulate the priority ranking factors of the productivity influenced by the personality of the field workers (logistics center workers) and functional workers (drivers) via the AHP technique Individual personality was studied by applying the Big 5 model of psychological factors (openness, Conscientiousness, extroversion, Agreeableness, neuroticism). In this paper, extraversion was critically analyzed as a priority factor. A trait of extroversion is a strongly active and individual personality. In this study, the field workers are logistics center workers and the functional workers are drivers. They are interactively influenced in the In & Out operation. For example, when it comes to 'up and down work' and 'inspection work', the functional workers perform 'up and down work' and 'delivery work' and the field workers perform 'inspection work'. Stressing on the respective work has an affect on work productivity. Inspection workforce has something to do with inventory management. Functional workforce affects the delivery workforce. Delivery work is positively correlated with customer satisfaction. Nevertheless, as a result of research, extrovert personality that has something to do with an energetic activity would not affect on the implementation of their operation. In addition, personal extraversion of workers and drivers in the warehouse can have a significant impact on job commitment and productivity improvement.

The majority of financial institutions are complying with the ratio of the total number of IT staff to total IT regulatory regulations, regardless of the size of the financial institutions and the scope of the information security work. The risk is spreading as a result of the information security workforce neglect their own work because of having multiple tasks. In this study, we propose a method to estimate the number of workforce needed in consideration of the size of financial companies and the characteristics of information security work, and to establish a systematic information security organization to respond more effectively to financial security accidents.

Background: The industrial revolution that took place in the United Kingdom (UK) between 1760 and 1830 led to profound social change. Occupational medicine was concerned with the diagnosis, treatment, and prevention of occupational diseases, that is, diseases directly caused by exposure to workplace hazards. A similar pattern of development has occurred globally. Methods: A review of relevant literature. Results: The international conceptualization and development of occupational health occurred during the 20th century. A new paradigm for occupational health has emerged that extends the classical focus on what might be termed "health risk management" that is, the focus on workplace hazards and risk to health to include the medical aspects of sickness absence and rehabilitation, the support and management of chronic noncommunicable diseases, and workplace health promotion. Conclusion: The future strategic direction for occupational health will be informed by a needs analysis and a consideration of where it should be positioned within future healthcare provision. What are the occupational health workforce implications of the vision for occupational health provision? New challenges and new ways of working will necessitate a review of the competence and capacity of the occupational health workforce, with implications for future workforce planning.

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.

In the United States, the Safety Rest Areas (SRAs) were introduced as highway roadside infrastructures in the early 1900s. The State Departments of Transportation (DOTs) operate/maintain their SRAs using different methods. The Washington DOT used the in-house workforce method for over 20 years, whereas some states moved to Performance-Based Contracting (PBC) from the in-house workforce to save cost primarily. Several existing studies claimed that using the PBC approach saved costs on several highway assets. Thus, the principal objective of this study is to compute and compare the unit operating/maintenance cost of SRAs using the in-house workforce method (in Washington state) with the PBC approach (in other states). The findings of this study show that the average annual cost using the PBC approach was much more than the average annual cost using the in-house workforce approach. The findings also show that in Washington state, the 'Labor Cost' category was a key expenditure, which is statistically higher than other categories. The 'Labor Cost' was followed by the 'Other Services', and then 'Materials and Supplies' and 'Equipment.' The study's findings indicated that outsourcing does not always save costs for agencies. The study findings may help transportation construction/maintenance professionals select a cost-effective approach for their future planning.

Purpose: The purpose of this study was to study the projected workforce of nephrology CNS in Korea. Method: Need models, ratio methods and expert opinion were used for projecting needs for the nephrology CNS. Result: In 2001, there are 28,046 ESRD(end stage of renal disease)patients, 304 renal replacement centers and 1695 nephrology nurses in Korea. the hemodialysis patients per hemodialysis nurse was 12. The number of nephrology CNS required to meet the demand for caring of ESRD patients in 2002, 2005 and 2020 was estimated at 616, 837 and 3105, respectively. 47 ESRD patients per nephrology CNS was revealed as a workforce standard before 2005. After 2005, It was 31 ESRD patients per nephrology CNS. Conclusion: This study founded the need to project future increments and development in supply of qualified nephrology CNS.

The purpose of this study is to analyze the current situation of farm labor and to propose directions to define government policies. First, present condition of family and employed agricultural workforce is analyzed. Second, characteristics in demand of agricultural workforce are analyzed in the consideration of distinctive types of each entity such as crop area. Third, currently existing agricultural workforce employment mechanism is researched and analyzed. Fourth, the policies and system related to agricultural labor market that have already been in practice are analyzed and tasks and direction in establishing those policies are proposed. This study will be helpful for policy makers to understand the agricultural labor markets and to build the institutional system for labor market services.

This paper develops an efficient heuristic algorithm for scheduling workforce level that can accommodate all the requested maintenance jobs. Each job has its own release and due dates as well as man-day requirement, and must be scheduled in a non-interrupted time interval, namely, without preemption. Duration of each job is not fixed, but to be determined within given specific range. The objective is to minimize workforce level to complete all the requested maintenance jobs. We show that the problem can be seen as a variant of the two-dimensional bin-packing problem with some additional constraints. A non-linear mixed integer programming model for the problem is developed, and an efficient heuristic algorithm based on bin-packing algorithms is proposed. In order to evaluate goodness of the solution obtained from the proposed algorithm, a scheme for getting a good lower bound for the optimum solution is presented and analyzed. The computational experiment shows that the proposed algorithm performs quite satisfactorily.

The purpose of this study is to propose empirically the improvement measures of labor conditions of the contingent worker. Since early 1980s, the labour market in Korea has given rise to a rapid growth in contingent worker. Last year, the number has shot over 7 million mark, with the ratio standing above the 50%. This study analyses the improvement measures of labor conditions of the contingent worker. This study present five major improvement measures of labor conditions of the contingent worker. First, It's establish of the relations between organizational flexibility of the labour market and the contingent worker. Second, It's needs to realize wages level of the contingent worker. Third, the contingent worker convert standard workforce step by step. Fourth, it's make no discrimination of the between contingent worker and standard workforce. Fifthly, the government place restrictions of the contingent worker rates.

The gamma-ray exposure doses in decontamination operation after a nuclear accident were evaluated with a consideration of various geometrical conditions and specific gamma-ray energies. The calculation domain is organized with three residence types and each form is divided into two kinds of geometrical arrangements. The position-wise air KERMA values were calculated with an assumption of evenly distributed gamma-ray source based on Monte Carlo radiation transport analysis using the MCNP code. The radioactivity is initially set to be unity to be multiplied by the deposition value measured in the actual accident condition. The workforce data set depending on the target object was determined by modifying the Fukushima report. The external exposure doses for decontamination workers were derived from the calculated KERMA values and the workforce analysis. These results can be used to efficiently determine the workforce required by the characteristics of the area and the structure to be decontaminated within the dose limits.
