전력 계통에서 계통 주파수는 부하의 변동에 따라 변화되어 연결된 발전기에 영향을 미치고 결국 계통에 커다란 지장을 초래한다. 그러므로 계통 주파수의 빠른 측정과 신속한 조속기 제어는 전력 계통의 안정성과 경제성에서 매우 중요한 부분이다. 과거의 전자기계식 주파수 계전기는 전력 소비가 크며 정확한 측정이 어려웠고, 이후 연구 개발된 디지틀 계전기는 노이즈와 왜곡의 영향을 많이 받으며, 최근에 개발된 Microprocessor 계전기는 고가의 장비에 50ms에서 수초정도의 주파수 측정시 시간상의 문제점을 가지고 있다. 본 연구에서는 주파수를 신속하고 정확하게 측정할 수 있는 개선된 알고리즘을 Matlab 프로그램에서 시뮬레이션하고 DSP6713 KIT에 프로그래밍하여 작동하였다. 임의의 전압파형을 DSP에 입력하고 동작시킴으로서 신속하게(약 30ms) 정확한 주파수를 측정하여 알고리즘의 효용성을 구현하였다.

The increase of the alternate current frequency results in increased rotational speed of the electrical motors and connected pumps. The consequence for the reactor coolant pumps is increased flow in primary coolant system. Increase of the current frequency can be initiated by the subsynchronous resonance phenomenon (SSR). This paper analyses the implications of the SSR and consequential increase of the frequency on the nuclear power plant safety. The Simulink $MATLAB^{(R)}$ model of the steam turbine and governor system and RELAP5 computer code of the pressurized water reactor are used in the analysis. The SSR results in fast increase of reactor coolant pumps speed and flow in the primary coolant system. The turbine trip value is reached in short time following SSR. The increase of flow of reactor coolant pumps results in increase of heat removal from reactor core. This results in positive reactivity insertion with reactor power increase of 0.5% before reactor trip is initiated by the turbine trip. The main parameters of the plant did not exceed the values of reactor trip set points. The pressure drop over reactor core is small discarding the possibility of core barrel lift.

The society for conservation of local historical properties in Korea originated in Japan. It was transplanted by Joseon Governor-General to represent their positions in the field of the conservations of the cultural properties. Also the society for conservation of local historic properties represented the positions of the provincial government office because the representatives of that societies were the chief of local government offices. At that time, the fundamental concept of the historical property conservations was not settled, so they accomplished the conservation activities as the necessary way for themselves.They often made a proposal about repairs for conservation of historical building and suggested a application for the national budget. And they contributed to carry out the repair works of the historical properties in the early Japanese colonial period. But they was usually used to invigorate the tourism and to publicize the regional characteristics through the historical properties. Although the societies were privately-managed as a matter of form, they were governmentally-managed as a matter of fact. It was the limits of the societies for conservation of local historical properties at that time.

Purpose - It is chaotic when doing a business without legal patterns and rules; individuals who make legal decisions without legal consideration are often protecting their interests and forgetting others. This study aims to suggest key solutions how companies can make better decision based on legal considerations through investigation comprehensive literature analysis. Research design, Data, and methodology - This research conducted qualitative textual method and a technique called 'Qualitative Comparative Analysis' (QCA) can be used to understand better why certain things change while others do not. In tough situations, QCA is a strategy for comparing several occurrences. Result - Total six considerations were founded by the QCA for better corporate decision. Based on these considerations, all stakeholders, shareholders, and every employee should nominate and vote on one person to be their leader in the organization; fair practices in choosing the governor of the organization through legal binding will bring peace and order to the company. Conclusion - It was time consuming to go through every detailed material that entails legal consideration in making corporate decision. The concept of same profile in the research is critical whereby many authors are using same concept to write their articles and books. Using pure concept from one source limits the research and gives inadequate information.

Objectives : This paper analyzes the new Majinhwiseong(麻疹彙成) manuscript discovered in Jeonju. The Majinhwiseong is a medical book specializing in measles co-authored in 1798 by Lee, Won-pung and three doctors from a middle class family. Until recently, the Handok (Korean-German) Medicine Museum copy was known to be the only existing version, but a new manuscript was recently discovered. Methods : The author, bibliography, organization, cited literature, and content of the book were studied. The contents of the Handok Museum of Medicine copy and other manuscripts were compared then reviewed. Results : 1. The book shows that middle class workers in the late 19th century were able to collaborate based on the results of their craft and form strong bonds. 2. The book was being prepared for publication in Pyeongan Gamyeong in December 1798, but failed to be published due to the sudden death of the Pyeongan-do governor. 3. For a correct understanding of this book, it is necessary to study the Handok Medicine Museum edition and the newly discovered manuscript (Jeonju edition) together. Conclusions : The two editions are of a different lineage. The Jeonju edition is overall more specific, while some parts are more detailed in the Handok edition. In conclusion, the Majinhwiseong is a book that was written by middle class doctors of late 18th century whose clinical experience was combined with Chinese medical theories. The book was specifically targeted to professional medical audiences.

Due to Japanese imperialism's invasion of Korea and the policy of exterminating national culture, many independence activists from Korean medicine participated in the Manchurian Independence Army activities and the fight for freedom. Kang Woo-kyu, who threw a bomb at the governor-General of Korea on September 2, 1919, can be cited as a leader who learned East Asian medicine. Kim Kwanje, who organized a secret organization by opening an East Asian medicine clinic in Gimhae, Gyeongsangnam-do, was involved in the struggle of the medical corps while working as a medical student. He is accused of providing a shelter by treating members of the Uiryeoldan. In 1919, the Manchurian Independence Army unit, which launched the March 1st Movement armed struggle, was established, and those who served as military doctors in various organizations can be found. Park Se-jung, who participated as an independent soldier at the age of 47, treated wounded soldiers and patients as a military doctor. A branch office was also created by raising military funds and participating in the Provisional Government of the Republic of Korea. Jang Hyong was able to raise independent military funds, campaign for the provisional government's independence petition, and lecture across the country mostly disguised as an East Asian medicine doctor, which led to several imprisonments for "fraud charges under the guise of similar medical practices".

Objectives : Daechu (Dazhui:GV14 (Governor Vessel 14))-point is located between the spinous process of the 7th cervical vertebra and that of the 1st thoracic vertebra. GV14 has been used to treat hypertension, high fever, neck pain, common cold, headache and so on. Hypertension often negatively affects the improvement of stroke patients. We investigated whether wet-cupping at GV14 had any effect of decreasing blood pressure (BP). Methods : In this study, 81 stroke patients were studied, from Oct. 2000 to Sept. 2001. They were composed of a Sample group (n=36) and Control group (n=45). The Sample group (n=36) was divided into Sample-Normal (n=9), Sample-Mild (n=7), Sample-Moderate (n=l1), and Sample-Severe group (n=9). The Control group (n=45) was divided into Control-Moderate (n=34) and Control-Severe group (n=ll). We checked blood pressure 5 times (just before treatment, then after 30,60, 90, and 120min. (2hrs.)) in each sample group and 3 times (baseline, after 30, and after 120min. (2hrs)) in the control group. Results : In a comparison of before-treatment BP and after-treatment BP in the sample group, SBP significantly decreased as time passed, while DBP slightly decreased but not significantly. In comparison of BP differences in each sample subgroup, BP slightly increased in the Sample-Normal group, but significantly decreased in the Sample-Mild, Sample-Moderate, and Sample-Severe groups. In comparison of BP differences between the sample and control groups, SBP and DBP of the sample group definitely decreased more than those of the control group, but not significantly. Conclusions : This study suggests that wet-cupping at GV14 has significant decreasing effectson blood pressure in stroke patients. Accordingly, we hope that this measure will be used more widely as an emergent treatment for increased blood pressure.

Objectives : The purpose of this study was to investigate the effect of acupuncture treatment (AT) in the tendency of increase of the need for AT for the treatment of Parkinson's disease (PD) worldwide and to investigate the advancements in AT research in Korea and the future directions of research on this topic. Methods : Until May 2017, the PubMed, Scopus, Medline, and four Korean databases were searched. The searched keywords were "Parkinson's disease", "Acupuncture", and "Intervention study". The intervention groups from all screened original studies were analyzed and the methods used to determine the effect of AT on PD were examined. Results : A total of 17 studies were grouped by country on the basis of the first author's position, of which 10 studies were conducted in China, four in the United States, two in Korea, and one in Brazil. The most common type of intervention was electroacupuncture (nine studies), followed by AT (six studies), and a combination of AT and bee venom AT (two studies). The most frequently used acupoints in AT were Baihui (GV20), Taichong (LR3), Zusanli (ST36), Sanyinjiao (SP6), and Yanglingquan (GB34). The most commonly used tool for evaluation of PD was the Unified Parkinson's Disease Rating Scale III, which assesses motor functions. Conclusion : The screened studies reported that there were no adverse effects of AT on drug therapy, and AT reduced the dose of drugs used in PD treatment. Future studies on PD treatment with AT should use the acupoints GV20, LR3, ST36, SP6, and GB34, and the meridians Gallbladder meridian and Governor Vessel. Clinical studies on PD should use CONSORT or STRICTA to ensure the quality of national studies and allow the development of new tools for the assessment of the effect of AT on PD using the above criteria.
