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.

Most of the laws and standards relevant to technology in Korea bear a resemblance to those in 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 and our public works were under Japan control we have applied Japanese laws and regulations made by Chosun government-general. Independently from Japan the power electricity accepted power plants of USA, codes of NESC, ASME / ANSI, NEMA. Our generation and distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the harmonization of technological standards, certification construction testing in the trend of world. This paper is based on WTO / TBT agreement coming in effect after 12th, April, 1979. For Korea the distribution system has a strong resemblance to American system so that unconvertible because IEC 60364 originated from Europe while NEC originated from USA. This papers deals with the fundamental elements of electrical safety system with comparing IEC 60364 with NEC. This paper considers how engineers should apply NFPA 70(NEC) and IEC based on the comparison of NEC to IEC in relation to electrical installations.

정기영,김지훈,성열문,곽동주,추영배 경성대학교 공학기술연구소 2010 공학기술연구지 Vol.16 No.-

In order to investigate the possible application of ZnO films as a transparent conducting oxide (TCO) electrode for film-typed dye sensitized solar cell(F-DSC), ZnO:Al films were prepared by RF magnetron sputtering method. The effects of gas pressure on the structural and electrical properties of ZnO films were mainly studied experimentally. F-DSC using either a ZnO:Al or indium tin oxide (ITO) electrode were also fabricated separately under the same manufacturing conditions. The electro-optical conversion efficiency and fill factor of the F-DSCs using both ZnO:Al and ITO transparent conducting electrodes were measured and compared with each other. ZnO:Al films showed the minimum resistivity of 2.6 x10^(-3)Ω-cm and a transmittance of 91.7% under the experimental conditions of doping concentration of 2 wt% of Al₂0₃ and gas pressure of 5mTorr. ITO films fabricated at 5mTorr of gas pressure also showed the minimum resistivity of 1.5x10^(-3)Ω-cm and transmittance of 92.1%. Although the electrical resistivity of ZnO:Al is higher than that of ITO, the conversion efficiency of F-DSC using ZnO:Al was comparable with that of F-DSC using ITO. The conversion efficiency of F-DSCs using ZnO:Al and ITO electrodes are about 2.8% and 2.9%, respectively.

Purpose: The purpose of this study was to provide appropriate spiritual and comprehensive nursing care for elders admitted to hospital by identifying factors that affect their quality of life, anxiety about death, and spiritual well being and by identifying correlations between these variables. Method: From April 23 to June 30, 2007, 76 patients 65 years of age or older, admitted to the Bobath Memorial Hospital were enrolled in the study. The elders were questioned about their quality of life, anxiety about death, spiritual well being, and their demographic characteristics. The data were analyzed using t-t.est. ANOVA, and coefficient with SPSS for Window version 10.1. Result: This study shows that for most of the elders, quality of life was found to be higher than average at 3.29 out of 5.00. Also, anxiety about death was found to be higher than average at 2.45 out of 4.00. However, spiritual well being was found to be lower at 2.75 out of 6.00. The study showed that as quality of life improves, anxiety about death was reduced. There was no direct relation between quality of life and spiritual well being. There was no direct relation between anxiety about death and spiritual well being. Quality of life for elders was found to be related to gender (p=0.008), economic status (p=0.019), and relationship with family (p=O.OOO). Anxiety death was affected most by job (p= 0.024) and period of hospitalization (p =0.043). Spiritual well being was affected by education(p=0.014), religion (p=O.OOO), and children (p=0.028). Conclusion: The purpose of the study was to improve nursing services for elders admitted to hospital to improve the quality of their lives and spiritual well being and to reduce anxiety about death.

목적: hNIS는 갑상선 조직 외에 다른 조직들에서도 발현된다고 알려져 있다. 유방암 세포는 그런 조직들 중에 하나이며, 그에 의한 유방암의 방사성옥소치료의 가능성이 제시되고 있다. 본 연구에서는 유방암 조직에서 hNIS의 발현정도를 알아보고, ^99mTc-MIBI 유방스캔과 hNIS의 발현 정도와의 관계를 조사하여 보았다. 대상 및 방법: 본 연구에서는 유방암으로 수술을 시행했던 56명의 환자를 대상으로 하였다. hNIS의 발현은 면역조직화학염색에 의해서 평가되었으며, 그 결과를 ^99mTc-MIBI 유방스캔의 판정 결과와 비교하였다. 결과: 전체 56명의 환자에서 hNIS의 발현율은 41.1%였다. 병리학적 진단에 의해 침윤성관상피암종이었던 49명에서의 발현율은 42.9%, 관상피내암종이었던 7명에서의 발현율은 28.6%였다. ^99mTc-MIBI 유방스캔에서 국소섭취 소견이 관찰되었던 41명에서의 hNIS의 발현율은 31.7%였다. 비정상적인 섭취 소견이 관찰되지 않았던 15명의 환자에서의 hNIS의 발현율이 의미있게 높게 관찰되었다(66.7%, p>0.05). 결론: 유방암 환자에서의 hNIS의 발현율은 그다지 높지 않았다. ^99mTc-MIBI 유방스캔에서 섭취증가 소견이 없을 때 hNIS의 발현율이 더 높았다. Purpose: Human Na^+/I- symporter (hNIS) is known to be expressed in many tissues other than thyroid gland. The breast cancer cells are one of them and the possibility of radioiodine therapy in treatment of the breast cancer may be suggested. We investigated the expression rate of hNIS and the relationship between the expression of hNIS and the finding of 99mTc-MIBI scintimammography in the breast cancer. Materials and Methods: Surgically proved 56 patients with breast cancer were the subjects of this study. The expression of hNIS were evaluated by immunohistochemistry and the results were compared to the findings of 99mTc-MIBI scintimammography. Results: Overall expression rate of hNIS was 41.1% in 56 patients. According to the pathologic diagnosis, it was 42.9% in 49 patients with invasive ductal carcinoma and 28.6% in the 7 patients with ductal carcinoma in situ. The expression rate of hNIS in the 41 cases with a focal increased uptake at he breast lesion on 99mTc-MIBI scintimammogram was 31.7%. That in the 15 cases without any abnormal uptake on the scan was significantly higher(66.7%, p<0.05). Conclusion: The expression rate of hNIS in the patients with breast cancer was not so high. The rate was higher in the patients with no increased uptake at the breast lesion on 99mTc-MIBI scintimammography. (Korean J Nucl Med 2002;36;325-32)
