Precast Concrete apartments were main stream of domestic industrialized housing around 90's , and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel Stud and Unit Box have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the Open System basis. In this study, the design standard for Unit house will be established coping with the established preparing standard for design specifications defined by Architectural Law and Promotion Law of Housing Construction. That is for design standard of industrialized private housing on the Open System basis.

In the hazardous areas where explosive liquids, vapors and gases exist, electrical apparatus/equipment should have explosion-proof construction. The consuming of liquefied natural gas(LNG) has markedly increased in the industrial field, especially in aspect of some thermoprocessing equipment, boiler, dryer, furnace, annealer, kiln, regenerative thermal oxidizer(RTO) and so on. Because it has many merits, clean fuel, safety, no transportation/storage facility and so on. It is strongly recommend that the classification of hazards has to be decided to prevent and protect explosion which may occur in thermoprocessing equipment. In this paper, the operated thermoprocessing equipments in industrial area investigated and explosion risk assessment about LNG leakage from its facilities was performed through numerical calculation and computer simulation. Finally, we suggest the systemic/technical approach for safety assessments of thermoprocessing equipments consumed LNG fuel which are specially subjected to classification of hazardous area.

The cogeneration system has a advantage of producing electrical and thermal energy simultaneously. therefore, this system is encouragable to the business proprietor and the nation like us which has the problem of limited energy. Presently, there is a few cogeneration system for new city and industrial complex. But the building cogeneration system is dull in application because of legal limitation and poor tax support. In this paper, we simulate economic propriety of the building system under the support which is applied to industrial system. And we simulate the effect of each support item on the economic propriety in aspect of payback period.

The similar point of the 19 regional industrial clusters of Japan is that all of the clusters are not limited to an administrational district but rather covers a larger area. When a cluster covers a larger area, there is problem of acquiring responsible businesses and interactive planing. In order to overcome such a problem, private coordinating organizations have been installed and operated to connect and manage inter-activities of industries, universities, and research institutes. TAMA, a private coordinating organization, differs from other associations in a way that it does not deal with one specific field or business. TAMA rather dealswith various product-developing small to middle size companies by offering strategic support for the development of new technologies and expansion of new businesses. Product-developing small to middle size companies comparatively have their own abilities for technological development and marketing which is quite different from other subcontract companies and their relations to large corporations. In such aspect, product-developing companies are actually similar to large corporations with competitiveness in the world market.

Wind tunnel pressure tests were conducted on a 1:100 scale model of a large industrial building with solar panels mounted parallel to the flat roof. The model form was chosen to have the same aspect ratio as the Texas Tech University test building. Pressures were simultaneously measured on the roof, and on the topside and underside of the solar panel, the latter two combining to produce a nett panel pressure. For the configurations tested, varying both the lateral spacing between the panels and the height of the panels above the roof surface had little influence on the measured pressures, except at the leading edge. The orientation of the panels with respect to the wind flow and the proximity of the panels to the leading edge had a greater effect on the measured pressure distributions. The pressure coefficients are compared against the results for the roof with no panels attached. The model results with no panels attached agreed well with full-scale results from the Texas Tech test building.

This study was to identify the effect of the satisfaction of certification, the educational use of the company offering certificate, the system of confirmation of the same model and the demographic aspect on the companies to see if compulsory certification(KC certificate) has negative effects on company management. First, the satisfaction of certification could reflect positive influences on company management. Second, there is no statistical significance in the education from the company offering certificate as a result of analyzing relationships but education is required and has an effect on improving quality according to the result of frequency analysis. Last, the system to declare by identifying the same model has a difference in significance in sales account, the development of products and warranty service for products.

Due to the increasing demand for convenience and simplicity, Home Meal Replacement (HMR) has become a key trend in the food service industry. This study researched the current consumer trend and analyzed the national and international HMR product trend, aiming to find useful insights for the field. Results showed that in order to expand the HMR market demand, it is possible to consider diversifying the product category by making customized premium products, such as products for the elderly, infants, patients, and sports players, or products with enhanced nutritional fortification. From the industrial aspect, centralization through Central Kitchen (CK) and implementation of the scientific and advanced ISO and HACCP system are necessary. Lastly, to develop high value-added HMR products, it is deemed essential to utilize the so-called 'food tech', the technology which integrates core technologies of the fourth industrial revolution into the food industry.

In this paper we settle some polynomial identity which provides a family of explicit Waring decompositions of any monomial Xa00 Xa11··· Xann over a field k. This gives an upper bound for the Waring rank of a given monomial and naturally leads to an explicit Waring decomposition of any homogeneous form and, eventually, of any polynomial via (de)homogenization. Note that such decomposition is very useful in many applications dealing with polynomial computations, symmetric tensor problems and so on. We discuss some computational aspect of our result as comparing with other known methods and also present a computer implementation for potential use in the end.

Recently, in the semiconductor industry, memory device market is focusing on producing ultra-thin wafers for high integration. In the wafer manufacturing process, wafers after backgrinding and CMP process must be picked up as individual dies and subjected to be peeled off from the dicing tape. However, ultra-thin dies are vulnerable to the possibility of breakage and failure in their thickness and size. This research studies the mechanism of peeling a die with a high-aspect ratio using a thermopneumatic method instead of a die ejector with physical pins. Setting compressed air and the temperature as main factors, we determine the success of the digester using thermopneumatic system and analyze the good die to find the possibility of making mass-production equipment.

한국의 경제발전은 세계적으로 잘 알려져 있고, 또한 많은 이론화의 대상이 되어 왔다. 이에 견주어 한국발전의 공간적 차원에 대해선 그렇지 못해 왔다. 사실, 한국의 지역(산업)정책은 한국의 발전레짐을 공간적으로 업그레이드시키는 데 주효한 역할을 했다. 이 논문은 한국의 지역산업정책을 산업경제를 바탕으로 했던 구지역정책과 신지식경제를 바탕으로 하는 신지역정책으로 구분하되, 특히 후자의 성공적 작동 요인을 분석하는 데 초점을 두고 있다. 한국경제의 선진화와 더불어 직면하게 되는 새로운 지역정책의 도전을 살펴보면서 지역정책의 향후 보완과제도 함께 검토한다.
