  • This research investigates the rising new role of mileage system as private e-money in a exploratory study. The key research questions are "How does mileage system evolve with expansion of e-business and what are the cases for real experiences in 'money-like' mileage and their implications?" This research focuses on the proposition that mileage points created in commercial transactions as a royalty program are observed to serve a new role as payment tool. In an attempt to identify factors that determine mileage system as private money, we employ three factors: confidence, transaction cost, and monetary freedom. Also, this research proposes a direction for further research and follow-up studies to establish legal and institutional issues and the relevant architecture, all of which are essential elements to make the mileage points global money with a certain trade ratio in the near future.

  • Construction delay is one of the basic constrains to achieve the project objectives in developing countries. This study aims to find the causes and effects of construction delays in developing countries. A thorough literature review has been done following the content analysis method. The relevant literature of 28 developing countries was collected from the scholarly journals published in the period of 2006 to 2016. The different developing countries are grouped into three geographic regions, i.e. South and Southeast Asia, Middle East, and Africa. In these regions, total 53 potential causes of delay under 8 major groups are identified. Frequency and ranking of these factors have been done. The factors, delay in progress payment by owner, contractors' cash flow problem, improper planning and scheduling, poor site management, and change order by owner during construction, are acknowledged as critical causes of delay in developing countries. This study will assist both academic and professional experts providing more insight about the construction delays and project management in developing countries.

  • The production of oxygen and hydrogen from solar water splitting has been considered to be an ultimate solution for energy and environmental issues, and over the past few years, nano-sized semiconducting metal oxides alone and with graphene have been shown to have great promise for use in photocatalytic water splitting. It is challenging to find ideal materials for photoelectrochemical water splitting, and these have limited commercial applicability due to critical factors, including their physico-chemical properties, the rate of charge-carrier recombination and limited light absorption. This review article discusses these main features, and recent research progress and major factors affect the performance of the water splitting reaction. The mechanism behind these interactions in transition metal oxides and graphene based nano-structured semiconductors upon illumination has been discussed in detail, and such characteristics are relevant to the design of materials with a superior photocatalytic response towards UV and visible light.

  • Studies of epidemiological and prognostic factors are very important for oncology practice. There is a rapidly increasing amount of research and resultant knowledge in the scientific literature. This means that health professionals have major challenges in accessing relevant information and they increasingly require best available evidence to make their clinical decisions. Meta-analyses of prognostic and other epidemiological factors are very practical statistical approaches to define clinically important parameters. However, they also feature many obstacles in terms of data collection, standardization of results from multiple centers, bias, and commentary for intepretation. In this paper, the obstacles of meta-analysis are briefly reviewed, and potential problems with this statistical method are discussed.

  • Purpose - This work aims to study the existing management process and methods of statistical evaluation of personnel mobility management, and propose improvement measures. This is particularly relevant in today's market economy because proper organization of personnel movement affects the availability and effective utilization of human resources in enterprises. Hence, it influences the volume, timely execution of work, equipment efficiency, and consequently the volume of production, its cost, profit, and other economic indicators. Research design, data, and methodology - We investigate the indicators that measure staff mobility, and their dependent consequences. Further, it analyses the factors influencing high staff turnover, which is a main indicator of staff mobility. Results - Measures for staff mobility development and prevention of turnover are proposed. Micom Systems is a sample case that has developed special programs to reduce staff turnover. Conclusions - Staff mobility leads to additional costs, significant loss of working time, and increase in defects. However, the advantages of staff mobility outweigh these negative factors. The role of staff mobility in a market economy cannot be overestimated.

  • Just-In-Time production is to keep the kanban system. When production managers implement and operate successfully the system in the multi-Line, multi-stage production setting, it is very important to determine the number of kanbans in deterministic kanban system under consideration with relevant factors as well as with cost. In concrete, we discuss about following factors in kanban system and provide a model formulating the multi-objective goal programming : Demand, stock on hand in process, Inventory cost and Labor cost, Vendor's suppling capacity, Work Load. Finally we analyze several numerical examples in order to test the model and attempt to expand the model in general case.

  • Purpose: This study was to understand to the nursing theory frame contained in the traditional philosophy and western nursing theory for the theory development fit for Korean people and to identified the strategy for nursing theory development. Method: To perform this study various relevant texts-western, eastern, classical and contemporary were reviewed. Result: The metaparadigm of the nursing in western considers four major factors-Human being, Environment, Health and Nursing. In Korea, the metaparadigm of nursing considers three major factors-Universe, Human being (body, life, health, disease) and Nursing. The key strategy for establishing comprehensive nursing theory which combines both western and eastern is to study the nursing literature based on eastern and western philosophy. Theorists should study the life and culture of the specific nation in order to understand the essence of the thoughts and psychology of the patients and to investigate the phenomena, which will be the foundation of theory development. Conclusion: Western nursing theory must be utilized to provide practical framework for the development of nursing theory, and practical approach is necessary for combining western and eastern theory.

  • The purpose of this study is to investigate how three factors--designer's capability, product market strategy, and product organization--supposed to determine the design process are related to each other. These factors influence Korean knitwear companies' market performances. For this purpose, we did not only library research on relevant theories such as the transaction cost economics but also empirical research largely based on a questionnaire. The respondents of the questionnaire were 59 designers, merchandisers(MDs), and top managers of knitwear companies located in Seoul. We analyzed the collected questionnaire data by using such statistical tools as χ²-test, t-test, and one-way ANOVA. Findings of this study were as follows. While there was a significant relation between organization form and designer's capability, no significant difference in designer's capability was found between trust enhanced network and unenhanced network. No significant relation was found between organization form and product market strategy, in discordance with Carney's arguments. Also, it appeared that there was no significant relationship between knitwear companies' product market strategies and their designers' capabilities.

  • Traction has been used since ancient times in the treatment of painfull spinal conditions, but the literature on traction and its clinical effectiveness Is limited. Traction can be defined as a drawing or pulling tension applied to a body segment. Cervical traction is a technique that applies a longitudinal force of the cervical spine and associated structures. Goals of traction include reduction of radicular signs and symptoms associated with conditions such as disk protrusion, degenerative disk disease, lateral stenosis, muscle spasm, and subluxations. The various mechanical factors most relevant to cervical traction are organized and discussed. The factors presented are 1) angle of pull, 2) Traction force, 3) duration of traction, 4) neck position and clinical application, and 5) frequency of treatment. It should allow physical therapists to adjust traction protocol to match the patient's symptoms and diagnosis. The purpose of this study is to provide a comprehensive overview of the cervical traction and treatment guidelines.
