In this paper, we present the DEA (Data Envelopment Analysis) application case study to investigate the regionally distinctive telco management characteristics of the Asia-Pacific countries. This study attempts to exploit the implications of DEA for the assessments of core process capabilities of telcos. Accordingly, we extract input variables of CAPEX (capital expenditure), operating expense, marketing expense, and number of employees, each to reflect the competitiveness of the core processes such as fixed asset utilization, operation & sales efficiency, and white collar productivity. In conjunction with the input variables, the output variables are chosen as EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization), ARPU (Average Revenue per User), and number of subscribers. The computational testing results, conducted with total 37 telcos of the 12 Asia-Pacific countries, are analyzed in various ways to understand the distinctive performance characteristics across the region. The managerial implication captured from this study provides useful insight for using DEA as the international telco management purpose.

With increase in oil demand owing to economic growth in Northeast Asia, the establishment of an oil hub in Korea is recently considered by policy and academic circles. This paper aims to suggest strategic schemes on the establishment of Korea's oil hub in Northeast Asia by comparing Korea's conditions as an oil logistics hub with Singapore which has been an oil hub in East Asia until recent year. Quantitative and qualitative analysis methods were employed in order to examine the competitiveness of Korea's oil hub. This research concludes that Korea is very competitive as an oil logistics hub in Northeast Asia, but so much improvements for realizing the project are necessary such as expansion of storage facilities for oil, institutional instruments for facilitating oil logistics and trading and preparation for incentive schemes on foreign investments in oil and its related industries.

본 고에서는 실태조사를 통해 국내 홈네트워크 산업의 시장 및 수출 현황을 분석하였으며, 아울러 홈네트워크 장비산업의 경쟁력을 평가하였다. 2005년도에 국내 홈네트워크 산업의 시장규모는 전년도인 2004년도의 7,104억 원에 비해 53.3% 증가한 1조891억원에 달한 것으로 나타났다. 이중에서 홈네트워크 장비시장이 87%인 9,4701억원에 달했으며, 홈네트워크 서비스시장은 13%인 1,421억 원으로 나타났다. 수급 현황 분석결과 국내 홈네트워크산업은 아직 기대에 비해 본격적인 성장단계에 접어들지 못한 것으로 보인다. 한편 국내 통신장비산업의 경쟁력 또한 4개 장비분야 모두가 경쟁력이100점 만점 기준에 60점대에 머무는 것으로 평가되어 선진기업에 비해 낮은 것으로 나타났다. 특히 브랜드경쟁력과 유통경쟁력이 공통적으로 현저하게 낮은 것으로 나타나 기술개발뿐만 아니라 마케팅 역량 향상을 위한 업계 자체의 노력 및 정부 차원의 지원이 시급한 것으로 나타났다.

In order to improve the international competitiveness of ferrule industry, the core technology of the second stage for ferrule grinding system is under developing. A high speed (10,000RPM) and high precision spindle system(Radial Runout 0.2 micrometer) bearing more cutting torque and force is designed considering the limitation of cost and size, the effect of heat, and various work-piece materials. A CAE software for machine elements and general machine system is used for preliminary evaluation and selection of design parameters. A dedicated program for the analysis of spindle system is used for final evaluation and selection of design parameter. The process how to evaluate and select using such tools are presented.

For the domestic glasses industry to procure competitiveness in the world CA(Cellulose Acetate) frame of spectacles market, CNC machining system for CA frame including high-value added CA cutting technologies should be developed with new materials for the rim based on Cellulose and sheet manufacturing base. The spindle system of glasses frame equipment that is the core to the quality of CA frame is the key technologies to realize high-speed, high-precision so its importance is remarkably emerging. In the study, at the structural design of the high spindle system of the private equipment for CA glasses frame embedded a motor of 40,000rpm, the stability of design was analyzed and investigated through selecting lubrication structure and thermal characteristics of the spindle system.

Prevention of the disasters is the best welfare to workers and it brings the growth and stability of an enterprise, finally uplifts the national competitiveness. Because small-scale businesses do not have safety and health managers, the government provides a wide range of safety and health management supports to small-scale businesses. However despite of this government's effort, the industrial accident rate of small-scale businesses does not decline, which is mainly because the projects are not differentiated according to the risk level of individual business. Therefore, this paper aims to obtain implications concerning a plan to conduct a reliable assessment of education through a safety job assessment, and to build a framework which may improve a technical area through the AHP analysis.

RAMS is becoming increasingly important in the decision making process for the rolling stock projects in order to improve competitiveness by reducing system life cycle cost while improving reliability, availability, maintainability and safety. In order to apply and manage RAMS of rolling stock systems effectively in the operator perspective, it is essential to integrate and control RAMS systematically from the early stage of rolling stock projects. RAMS management is to implement a RAMS system into rolling stock projects in terms of a rolling stock operator, which presents the strategic directions of RAMS policy, objectives, requirements, control, analysis, measurement and improvement throughout life cycle of rolling stock projects. This article presents a new framework of RAMS management that provides an effective and efficient way for managing RAMS in rolling stock systems in the railway industry.

Transportation cost takes a major portion on logistics cost. The reduction of transportation cost is a key issue to achieve national competitiveness and logistics cost reduction. And railway must play a important role to shift from road freight transport to environment-friendly transport. There are many idle freight cars in railway freight transportation and they give rise to inefficient operation of freight car. It is well known that the main reason of idle freight cars is unbalanced demand according to direction. In this study, we analysed the current status on idle freight cars in railway at the level of daily data. This results help follow-up research to cut down idle freight cars in railway.

Objectives : This study compared Value added to personnel expenses between 12 private general hospitals and 12 regional public hospitals, based on location and size, to examine industry competitiveness in terms of management. Methods : From 2011 to 2015, the value added and value added to personnel expenses were calculated by year. and a SPSS statistical program was used to determine and influential factors between private general hospitals and regional public hospitals. Results : The total value added to personnel expenses was 26.85 percent lower than general hospitals compared to regional public hospitals. The product category most influenced by the value added to personnel expenses was Stationeries & expendables at general hospitals and Outsourcing at regional public hospitals. Conclusions : Regional public hospitals have relatively low value added to personnel expenses compared to the general hospitals. Therefore, it is necessary for hospital management to reexamine gross revenue relative to total manpower.
