지식정보사회에 있어 국가의 경쟁력은 유용한 지식과 정보가 얼마나 효율적이고 효과적으로 유통될 수 있는가에 따라 결정된다. 이에 정부는 제2차 국가GIS구축 기본계획을 수립하고 '지리정보의 전 국민 인터넷 유통 및 활용'을 목표로 국가지리정보유통망을 구축하고 있다. 그러나 각 부처별로 생산 구축한 지리정보를 유통하고자 하는 노력들이 동시에 진행되고 있어 다양한 경로로 여러 유통망에 접근해야 하는 문제가 제기되었다. 그러나 모든 시스템의 특성 및 환경에 부합하는 일원화된 연계방안을 제시하는 것은 어려운 일이다. 따라서 본 연구에서는 국가지리정보유통망과의 연계를 위해 고려해야 하는 사항이 무엇인지 연계 요소를 도출하고, 각 연계 요소별로 유형화한 연계방안을 제시하여 국가지리정보유통망과의 연계에 필요한 기준을 마련하였다.

The purpose of this study is to suggest the direction for the development of intelligent agricultural machinery technology in the Republic of Korea. For this purpose, intelligent technology of agricultural machinery was divided into autonomous agricultural machinery and tractor-implement intelligent communication technology. Then, a survey and analysis of a previous study of the Republic of Korea and foreign countries were conducted. GNSS-based autonomous driving technology is still widely used worldwide, and recently, as research on camera and LiDAR-based autonomous driving is actively progressing, autonomous driving technology is becoming more advanced. ISOBUS-based technology is being developed worldwide for intelligent control of tractor-attached implements, and major global agricultural machinery manufacturers are actively applying it to their products. However, although some ISOBUS technologies are being researched in the Republic of Korea, there are no cases of application on agricultural machinery yet. Therefore, to be globally competitive in the agricultural machinery manufacturing industry, there is an urgent need to advance autonomous driving technology and commercialize agricultural machinery using ISOBUS technology.

21세기로 접어들면서 국가발전 동력은 '지식과 정보' 중심에서 '창의성(Creativity)'이 중요시 되는 문화기반 경제 중심으로 전환되고 있다. 창의적 문화 기반 경제 시대에서 국가 경쟁력을 좌우하는 핵심역량은 '문화콘텐츠'라 볼 수 있다. 현재 우리나라에서 추진되고 있는 유비쿼터스 사업의 특징은 RFID 중심의 인프라 구축으로 치중되어 실제 서비스를 제공받는 일반 국민의 인지도가 낮은 실정이다. 따라서 본 논문에서는 유비쿼터스 기반의 기술과 '문화콘텐츠'가 결합되어 보다 쉽게 접할 수 있는 문화서비스 추진방안을 4가지 측면으로 다룬다.

Recently, the high-rise building has been constructed competitively because it is symbol of the national competitive power including the technical power. The higher buildings are getting, the more important building mechanical systems are. So, the building mechanical systems are getting developed. Among the building mechanical systems, the sanitary system is basically necessary in order to maintain the building hygienically along with convenience and safety. This study has been investigated for various cases of high-rise building plumbing system. As a result, a variety of zoning method has been applied to most skyscrapers depending on the building height in the building mechanical system. And a variety of joint have been applied to minimize the Shortening and Sway. Also, the drainage in same uses has been discharged outside of a build through the one vertical pipe line. And airing system has been used like Individual Vent Pipe Yoke Vent Pipe Stack Vent Pipe Loop Vent Pipe Relief Vent Pipe method. It is sure that this study could be used as the high-rise building design.

By development of renewable energy and more efficient facilities in an increasingly deregulated electricity market, the operation cost of distributed generation (DG) is becoming more competitive. International environmental regulations of the leaking carbon become effective to reinforce global efforts for a low-carbon paradigm. Through increased DG, operators of DG are able to supply electric power to customers who are connected directly to DG as well as loads that are connected to entire network. In this situation, a community energy system (CES) with DGs is a new participant in the energy market. DG's purchase price from the market is different from the DG's sales price to the market due to transmission service charges and other costs. Therefore, CES who owns DGs has to control the produced electric power per hourly period in order to maximize profit. Considering the international environment regulations, CE will be an important element to decide the marginal cost of generators as well as the classified fuel unit cost and unit's efficiency. This paper introduces the optimal operation of CES's DG connected to the distribution network considering CE. The purpose of optimization is to maximize the profit of CES. A Particle Swarm Optimization (PSO) will be used to solve this complicated problem. The optimal operation of DG represented in this paper would guide CES and system operators in determining the decision making criteria.

Purpose: This study aims to determine the needs of customers who use railroads as a mode of transportation and propose customer-oriented improvements in railroad technology by making connections between customer needs and railroad technology. Methods: We primarily used two methods for this study, AHP and QFD. First, AHP was used to evaluate the relative importance among the different components of railroad technology. Second, the QFD was applied to make a link between customer needs and railroad technology. Results: Railroad technology is largely divided into development, maintenance, and support. Empirical results showed the following improvement priorities in development, vehicle, system, line, signal/communication, power, and structure, in maintenance, vehicle, signal/communication, line, process, power, and structure, and in support, safety/precaution, management, environmental energy, operations/logistics, and station. Conclusion: Recognizing limitations in measuring the level of railroad technology when using the existing 'Technology Growth Model,' we used AHP and QFD to explore improvement directions for customer-oriented railroad technology. By offering customer-oriented services based on this study, railroad service providers will be able to acquire competitive advantage in the market.

The purpose of this paper look at the basis of the cultural differences of Korean and Japan by comparing the craftsmanship. Korean craftsmanship and master craftsman making traditional handcrafts and artwork would die out at a critical moment. The craftsmanship and system could not be established because of discrimination in the traditional four classes of society( scholars, farmers, artisans and tradesmen), invasions of other countries and discontinuity of tradition from modernization. On the contrast, in Japan, it was possible to establish traditional handcrafts and artworks, technique and craftsmanship with apprentice system and various social privilege and treatment even in the same traditional four classes of society ( scholars, farmers, artisans and tradesmen). It was common to pass down the family business for a hundreds of years with self respect between Japanese master craftsmen and lots of people succeed the family business will now. Japanese craftsmanship is originated from 'worship to god' Medieval Japanese believed that the thing changes human mind, artistic talent, masterpieces and faith were connected to sacred power. Therefore, master craftsmen and their works were also made by the power of god. In this context, craftsmen were protected and treated in socially and nationally. It is that the social treatments and supports in national level and their own pride and continuous training of techniques and abilities as the main driving force to maintain the craftsmanship in Japan. Korea has the sale level of competitive tradition and technique in comparison any other countries. Japanese craftsmanship study will be a critical data in the protection and maintenance of Korean traditional and technique.

In 1994, the house construction work was separated from design part to prevent incomplete work and to improve quality. During that time, the supervision in the house construction work has made a great development in the quantity phase, but there is no study case about the satisfaction degree of clients on the supervision job. This study presents the improvement schemes of the supervision job rationality, the revision of supervision system and supervisor's improved construction management ability. also, This paper aims at advancing our construction field and enhancing competitive power by seeking for solutions to problems and improving current system to a reasonable supervision in the house construction work comparing and analyzing by questionnaire in Taegu, Kyungbuk area. The further study will be needed about the whole Korean construction market.
