In Japan, the population progresses to the extreme aging society and it is entering the phase of the population decrease while the population increase is continuing in the world. The construction market is expected to shrink accordingly, however the situation of labor shortage is expected to continue at a faster rate, because the aging of construction workers is progressing and new younger labor force cannot be secured. In order to supplement the labor shortage, it is required to progress mechanization, automation, labor saving, and efficiency improvement by utilizing the information well in each stage in a series of flow of planning, design, construction, operation, and disassembly in one building. The measures to maintain and expand the construction market by the new efficiency improvement techniques which enhance the utilization degree of building information are required. Currently, the elemental technologies which utilized BIM (Building Information Modeling) are accumulated by advancing digitization in each phase. DX (Digital transformation) in the construction industry can be achieved by the technology maturing and having a series of continuities. It is anticipated that this will evolve to a new method which is unprecedented. Present status of BIM and mechanized constructions in Taisei Construction are introduced, and future prospect is described.

본 연구에서는 국내 항행안전시스템의 개선을 위해 현재 구축이 진행되고 있는 KASS를 중심으로 구축 과정에서 예상되는 문제점을 식별하여 여기에 대한 대응 방안을 제시하고, KASS 구축 후 예상되는 국내 항행안전시스템의 개선효과를 분석하여 정리한다. KASS 구축 과정에서 해결해야 할 과제는 정서적인 측면, 기술적인 측면, 비용적인 측면, 운행 안전성 측면 등 네 가지 관점에서 존재한다. KASS가 구축되어 운영되면, 정밀접근 및 이착륙까지 항행안전시스템을 사용하지 않아도 되므로 비용 절약, 항공로 혼잡 해소를 통한 결항 및 이·착륙 지연 감소, 항공기 수용 능력 확대, 탄소배출 저감, 미래 항공수요 대처 및 항공교통 안전성 향상, 항공사고 감소 등 많은 효과를 거둘 수 있을 것으로 기대된다. 결론적으로 향후 항공수요 증가로 인해 현재보다 더욱 극심한 경쟁 시대에 돌입하게 될 것으로 예상되는데, 이러한 경쟁에서 살아남기 위해서는 하루라도 빨리 KASS의 도입이 필요하다. 본 연구의 분석 내용은 이 분야의 학술적인 연구에서 참조할 수 기반 자료가 될 수 있을 것으로 기대된다. 본 연구의 내용을 바탕으로 향후 이 분야에서 연구가 추진되어야 할 내용 중의 하나는 KASS 도입을 통한 항행안전시스템의 변화를 보다 체계적으로 예측하고, 이러한 변화에 대응하기 위한 실질적이고 유용한 방안을 제시하는 것이라고 판단된다.

This paper is to reduce implementation time of POS system by applying QFD. All the related elements are classified by the hierarchical structure into three phases: expected quality, weight and evluation. The mentioned about includes the first and second improvement, and the case study of POS system of petrol stations in Taichung. The results of this research are shown in the following. 1. the first improvement was from average 76 days/station to 48 days/station. 2. the second improvement was from average 48 days/station to 36 days/station. 3. the ratio of target achievement was $162\%$

To keep an enterprise's competitiveness on the condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously in not only in production and maintenance but also in related industrial productivity. This paper presents the study of equipment reliability improvement for rotary-machine vibration analysis. Based on these analyses, the maintenance management information system, and the machinery condition diagnosis technique are studied by using of the real-time diagnostic. Therefore, it is expected to improve the efficiency of business processes in the production and safety when we use this system.

Selection of optimal cutting conditions is important for improving productivity and implementing efficient process control in metal machining. In this study, improvement of cutting conditions in machining using end-mills is studied by using deep-layered neural networks, which comprise an input layer, output layer, and two hidden layers. System networks are designed with inputs as cutting conditions, and they output the cutting force. A pseudo-inverse network is designed that has the adjustable cutting condition as output and cutting force and other cutting conditions as input. The combination of the system network and pseudo-inverse network enables selection or improvement of cutting conditions that results in the expected cutting force.

The equipment in ships and railway vehicles are continuously exposed to vibration, and its durability is very important. Therefore, consumers require the verification of the performance of equipment via standardized tests under the given environments to improve and stabilize the performance. In this study, a durability improvement and stabilization plan was proposed, which included the exploratory vibration test, variable frequency test and endurance test for the electrical equipment according to the vibration environment. It is expected that this study results will improve the technological competitive power of the ship and railway-related manufacturers and contribute to the equipment development and export.

The DDA negotiations, in 9th multilateral trade round, has focused on nine sectors including agriculture, non-agricultural market access, and service. After August 2004, member countries have intensified negotiations in order to reduce gaps between countries perspective. So most attention of members countries has been focused on agricultural trade and non-agricultural market access. Agricultural negotiation confront tough challenges because of different positions among members countries, and are not expected to reach perfect forms of modalities. Nevertheless based on the fact that many countries nearly reached agreement on some core. Under this circumstance, Korea has to prepare more practical strategics and more effective individual commitments to minimized the agricultural market opening. The other way, some Korean agricultural products will be exported by the DDA negotiation. Recently the understanding of Third-Party Logistics and Logistics Outsourcing are receiving increased attention as means of becoming competitive in agricultural products export improvement. So this paper presents a in-depth analysis for third-party logistics and its implications for Korea agricultural product export system improvement in E-trade Era.

The purpose of this is to analyze environment of foreign direct investment and Act in Korea and to find invitation and extension of foreign direct investment into Korea. Investment incentives, simplification of investment procedures, image improvement, increased public relations and investment support services are all factors which can be enhanced in the short term to positively influence investors decision-making in where to invest. Since the enactment of the Foreign Investment Promotion Act in November of 1998, there has been a signification improvement in Korea's investment environment in terms of policies and systems. It is expected that the foreign direct investment environment in Korea will continue to improve through the improvement in political stability, labor-management relations and easing of political tensions between the North and South, in the long term, as well as through improvements in investment incentives, investment procedures and public relations activities, in the short term.

The objective of the study is to assess the water quality improvement resulted from the rearrangement of the irrigation water supply systems at Mankyeong River and Ansung Chun basin. There is a mixed type of watershed composed of urban and rural areas in the region. From the water quality analysis, showed high T-N, T-P concentration in Ansung chun and Mankyeong river caused by paddies separated widely around Ansung chun and Mankyeong river and by runoff of the pollution from the Ansung and Jeonju city. but the upstream of the river showed clean water quality, so if we use the upstream water as river maintenance water for water quality improvement, it is expected to be positive effect for rural environmental aspect.

We assess service delivery system for outpatients of general hospital(A) using service blueprint. Service blueprint for outpatients' service process currently being implemented in general hospital(A) is analysed to improve hospital services and define hospital service delivery system more accurately. In addition, comparative analysis of service blueprint between before and after improvement is conducted to find that health care services Is now more customer-oriented and hospital employees can link their duties to service delivery system. Dealing with the efficiency of health care service delivery system based on service blueprint analysis is expected to pave the way for continual service quality improvement of general hospitals in the future. The analysis of service blueprint of outpatients' service process suggested in this study is useful for setting strategies for health care service. It also helps service process design and service digitalization of other general hospitals in the future.
