  • BLUs are major component in LCD industry which occupies 90% or more of FPD market worldwide and BLU market is expected to be expanded continuously according to the trend of miniaturization, slimness, low power consumption and low weight. The larger the BLU market scale, the more important standardization of performance evaluation techniques to clearly prescribe the product specification. Currently the government is promoting the establishment of related laws and coincidence with international standards to cope with agreements such as WTO/TBT, but the nongovernmental standardization activities are not enough to be actualized. Furthermore, BLU related components such as CCFL, EEFL, inverter and reflector are already developed for localization to substitute imports with home products but collective standardization, national standardization, and international standardization are still not done. So, performance specifications and evaluation methods for normal fluorescent lamps or industrial lamps are being adopted and used as national standards and safety certification standards instead. Making these standards enables to prepare a chance to penetrate into global market and to promote world best products. Also, by making this collective standard, it provides chances to take part in international standardization activities, to protect domestic industries and technologies, to obtain the trend of advanced technologies, and to be predominant over other countries. That is to say, CCFL standardization helps raise 21st century national strategic technology policy and go ahead of globalization of core technologies.

  • Bird collisions with glass are a substantial source of human-caused avian mortality. It has been estimated that between 100 million and 1 billion birds die in collisions with windows every year, and bird-window collisions can have a particularly serious impact on populations because glass is dangerous for strong, healthy, breeding adults. The purpose of this study are to address the bird-window collision issue and to provide suggestions for bird-safe development by reviewing precedent studies on bird collision and analyzing bird-friendly design guidelines. Typically reflections of the sky, clouds or trees on glass, green plants in lobbies, and lights attract and confuse both migrating and resident birds. Therefore birds fatally fly into the glass because they do not recognize that reflections are false and that glass is a barrier. Many cities such as Toronto, Chicago and New York have made efforts on reducing the bird collision by encouraging the creation of environmentally conscious and bird-safe buildings. The USGBC also introduced a bird-safety credit as part of its environmental certification process, called LEED. The results of the study presented that architects and builders can help reduce or prevent bird from collisions in both new construction and existing structures with creative use of design elements. The measures to reduce bird collisions include using glass with an embedded pattern, opaque or translucent films, decals, dot patterns, awnings, louvers, and grilles. Turning off lights after midnight during the spring and fall migrations can be part of the solution as well. In order to reduce bird mortality, the most important thing is to generate awareness of the issue among designers, builders, as well as the public. Also local governments need to develop bird-friendly design guidelines and planning mechanisms to encourage bird-safe development and building operation.

  • Safety of residents could be considered and then increased when we plan, design, and operate a city. In Korea, CPTED (Crime Prevention through Environmental Design) is currently being applied to new towns. However, it is not systemized and neither efficient, for there are no constraint provisions, and the foreign cases are not specifically customized to the current situation of the country. This means, the introduction of CPTED is an indispensable fact, but there are limits to the budget aids and actual application, for there is no legal base to support it. This study, therefore, aims to find the limits from analyzing related laws and regimes, administrative regulations, and applied cases, and to deduct improvement plans based on examined foreign cases. In this Study, the supporting system of foreign CPTED related laws and regulations was analyzed around the cases of England and U.S.A, and based on that information, the present condition and limits of CPTED related laws and regulations of Korea were deducted. As a result of this study, there were no constraint provisions to apply the design guidelines to actual planning, and there were limits on backup aid and actual application due to the lacking of analyzing the relevant area. Also, an acceptable framework must be arranged by the revision of laws and ordinances to compel the system, and link it with the CPTED certification system which will revitalize the whole system.

  • Most Technological laws of Korea are almost identical to those of Japan. Electricity was not introduced to Korea until lighting ceremony in Kyong-Bok palace observed in 1887. Since Korea was annexed to Japan in 1910, Korea have applied Japanese law and regulations made by Chosun government-general. And public works were under Japan control. Korea accepted adopted the power plants of America, codes of NESC, ASME / ANSI, MEMA while Japan accepted or adopted only IEC. Our generation distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the technological standards, certification, construction and testing are in harmony internationally. The WTO / TBT agreement came in effect after 12th, April, 1979. The sections in the agreement require the members to exchange their own standards and codes for the harmonized ones by degree. The Korean distribution system has a strong resemblance to American system so that the internal engineers are confused in application of the relevant standards. IEC60364 and NEC are technologically similar but practically unconvertible because both have their different originality, that is to say Europe and USA. This paper deals with the fundamental elements of electrical safety system on review of IEC 60364 and NEC. This paper considers how engineers should apply IEC60364 and NFPA 70(NEC) based on all-the-way review of them.

  • The purposes of this study which was conducted by inquiring into some curricula for Emergency Medical Dispatchers(EMDs) are to introduce a curriculum into Korea and develop a textbook for training of the EMDs in Korea. The conclusions from this study were summarized as follows; (1) There are some professional demands in our Emergency Medical Dispatch field therefore, now it is necessary to set up an education system for the EMDs in Korea and give them a suitable name to this change. (2) Some historical turning points which are condensed from the developmental process in the USA. including "Medical Self Help" with no formal dispatch protocols, Medical Priority Dispatch System, Practice Standard, Dispatch Protocols will serve as a good reference for establishing and education system for the EMDs. (3) To effectively train the EMDs in Korea, we needed to be introduced to Emergency Medical Dispatch : National Standard of Curriculum from the U.S. Department of Transportation & the National Highway Traffic Safety Administration which is made up Basic Emergency Medical Concepts, Information Gatherin & Dispatch, Introduction to the Emergency Medical Dispatch Protocol Reference System(EMDPRS) & 32 Chief Complaint Types. (4) The introduced curriculum closely related to the medical director, the direct indirect medical control, the scope of practice in the USA, should be revised for the Emergency Medical Service System of Korea. But to reduce the developmental process & time, it is necessary to postpone the consideration on these factors until publishing a new textbook. (5) This study which gives the cornerstone about some developmental methods on textbook for EMDs will be helpful to build up an education system for EMDs such as Curriculum, EMD Certification, National Academy of Emergency Medical Dispatch to fit the Emergency Medical Service System of Korea in the future.

  • Purpose: The increase in patients requiring hemodialysis has resulted in an increase dialysis-associated infections risk. but there are no Renal Dialysis unit design standard meet specified safety and quality standards. Therefore, appropriate Establish standards and legal regulation is important for the provision of initial certification and maintenance of facility, equipment, and human resource quality. Methods: Literature survey on the design guideline and standards of Renal Dialysis unit design in Korea, U.S, Germany, Singapore, Hongkong, Dubai. Results: There are no established standards for facilities in dialysis units in Korea. To prevent infections in dialysis patients, necessary establish standards. Considering the domestic and overseas Health-care facilities standards, the major factors to be considered in the medical environment for Renal Dialysis Unit are as follows. First, planning to separate Clean areas(treatment area) from contaminated areas(medical waste storage area). Second, ensure sufficient space and minimum separation distance. Although there may be differences depending on the circumstances of individual institutions, renal dialysis unit consider the space to prevent droplet transmission. Third, secure infrastructure of infection prevention such as sufficient amount of hand hygiene sinks. Hand washing facilities for staff within the Unit should be readily available. Hand hygiene sinks should be located to prevent water from splashing into the treatment area. Fourth, Heating, ventilation and air conditioning (HVAC) system for Renal Dialysis Unit is all about providing a safer environment for patients and staff. Implications: The results of this paper can be the basic data for the design of the Renal Dialysis Units and relevant regulations.
