중국의 자판기 시장은 여전히 가능성의 영역이다. 2008년 북경 올림픽 개최를 계기로 자판기 시장의 큰 성장이 예상되고 있는 반면 자국내 산업 인프라는 제대로 갖추어져 있지 못한 상황이다. 이렇다보니 많은 자판기 관련 해외업체들이 이 시장에 관심을 가지고 시장 진출을 추진하거나 눈독을 들이고 있다. 올 7월 20일부터 22일까지 개최되는 Automatic Vending System & Equipment Exhibition 2006 전시회는 중국시장 진출에 관심을 가지고 있는 업체들에 있어 구미가 당기는 전시회이다. 전시회 참가를 통해 해당회사와 제품에 대한 현지의 반응을 살펴볼 수 있을뿐더러 전반적인 현지 시장조사도 알차게 진행을 할 수 있다. 중국시장 진출을 위한 교두보로 국내 업체도 관심을 가질 필요성이 큰 이번 전시회의 면면을 살펴보기로 하자

The rapid progress toward the 4th industrial society has led to possibilities of fire increase. It is pointed out that, though initial fire suppression is emphasized, the current legal systems do not sufficiently recognize the importance of initial fire suppression. In order to resolve this, problems of the current legal systems and regulations, as well as fire-fighting facilities to be equipped according to the size of specific fire-fighting objects, were diagnosed. Also, suggestions for improvement were provided through comparative analysis with relevant laws and technical regulations of Korea and other countries. According to fire safety standards such as NFPA, IMO, ISO, and Russian standards, automatic fire extinguishers are to be installed as per the adaptability criteria of fire extinguishers and automatic fire extinguishers. In Korea, the "Act on Fire Prevention and Installation, Maintenance, and Safety Control of Fire-fighting Systems" cover the types and scope of fire fighting facilities that include specific fire protection objects, such as electric room, power room, and substation room. This study has identified that, in case of a place with a floor area of less than $300m^2$, the installation requirement is not clearly specified. Therefore, in this study, fire extinguishing equipment and automatic fire extinguishing equipment to be added for each sub-use application are proved to have fire extinguishing performance of Class A, Class B, and Class C, respectively. In view of the fact that, in overseas standards, all space except containing such materials as Deep fire, metal fire and peroxide, can be installed with fire fighting equipment, a legal system for specifying the capacity units of fire fighting apparatus by application is, in this study, proposed.

In this paper, we suggested the integration between automatic enforcement system and UTIS(Urban Traffic Information System) base station. UTIS base station and automatic enforcement system are different in the height of installation and the type of communication network. UTIS base station is 25 meter high and communicate with center system by optical network. Whereas automatic enforcement system is 6.6 meter high and communicate with center system by rental network. For the purpose of suggesting the efficient method of integration, research was as in the following. We found that the number of integrated system was 1,628 through the present state of analysis and UTIS equipment was satisfied with the required specifications through field testing. Also we suggested the appropriate configuration of the integrated system and analyzed that the cost of the integrated system installment is 1/5 lower than that of the legacy system installment.

In this paper, authors will develop the quick and precise remote controller of automatic fire detection equipment (P-type one-class receiver) based on information communication technology (IT). The remote controller detects the fire and disaster in the building automatically and quickly and then activates the facilities to extinguish the fire and disaster, monitoring such situation in a real time through wire-wireless communication network. The proposed remote controller is applied a programmable logic device (PLD) micom. of one-chip type which is small size and lightweight and also has highly sensitive-precise reliabilities. The one-chip type PLD micom. analyzes digital signals from sensors, then activates fire extinguishing facilities for alarm and rapid suppression in a case of fire and disaster. The detected data is also transferred to a remote situation room through wire-wireless network of RS232c and bluetooth communication, and then the situation room sends an emergency alarm signal. The automatic fire detection equipment (AFDE) based on IT will minimize the life and wealth loss while prevents fire and disaster.

In this paper, I purpose one of the development methods for portable Automatic field Test Equipment(ATE) with VME form factor. Almost portable ATE have not used to standards form factor and they are connected by mechanical non-rigid general connectors and wire harnesses among the components. Furthermore, it is hard to reuse developed board. So, it decreases to reusability of developed board and it is hard to maintenance of ATE. Even those things have weakness for vibration and drop test especially in portable ATE. The XK9A1 ATE using VME form factor has environmental reliability through vibration, drop, temperature test. It consists of 5 developed board called the control board, the wire & wireless communication board, the power supply board, the load board and the mother board. It is connected by two wire harnesses between mother board and extern circular connectors. The control board send the data and address to other board though each 16-bit data and 20-bit address line. You can develop the function board what you want to using those data & address line when it comes to needing other function board.

The goal of this study is to analyze an effect of productivity elevation. For the goal, the various methods of the productivity elevation were suggested and the system improvements were conducted. The S company was established in Ban-Wol Industrial Complex, Ansan-City, Kyonggi-Do on 2007. The company was hiring 22 employees. The main manufactures were heavy duty equipment parts and the amount of sale was two billion won on 2008. Problems which the company faced were ambiguous production target management and materials loss. To solve the problems, NCT work improvement and automatic welding were induced. There were steel saving of 3,780,000won/month and man-hour saving of 144,000won/month by redesign of the steel sheet for the NCT steel job. Also, changing from handwork to automatic welding, the man-hour saving for the welding job was 320M/H and saving of 4,225,600won/month. The others of systematic improvement for productivity elevation were usage of jig and daily equipment checklist.

In this study, we deal with the system design and development of the automatic page passing machine. In order to turn pages without injury of a book or a musical note, we used an inhalation motor. Also, when we turn over pages. the successive actions of fixation and inhalation are embodied by motors which are operated by a microprocessor. In traditional products. some limited pages must be fixed into the Turning Bar in advance. On the contrary, proposed equipment is able to turn over the pages of a book without laying the groundwork. Experimental results using produced facilities are presented to demonstrate the efficacy of the proposed equipment.
