Objective : To clarify the features of needling method in the Zhenjiu Jiayijing, the needling depth and needling treatment time were sorted out. Method : According to the analysis, we can identify the crucial factors of the needling features. Result : Compared with the needling related content of Huangdi Neijing(黄帝内经), the historical outline of the needling development could be found and the ancient acupuncturing process was reappeared with a historical perspective. This research will provide guidance for the literature research and clinical application. Conclusion : Zhenjiu Jiayijing, also an important and valuable literature, will provide more evidence or clues for depth and treatment time of needling, which will be helpful and meaningful in clinic.

최근 가상현실을 활용한 문화유산 콘텐츠들이 활성화되고 있다. 그러나 그 대부분은 증강현실이나 가상현실을 통해 단순 복원정보나 고증정보를 제공하는 데 그치고 있다. 이글에서는 메타버스의 4가지 유형을 통해 역사교육콘텐츠 개발방안을 살펴보았다. 첫째, 가상세계의 구현을 통해 학생들이 과거 신분별 아바타를 운영해 봄으로써 당시 생활을 체험해 볼 수 있다. 둘째, 증강현실을 통해 현재 체험해 볼 수 없는 사건이나 문화유산의 현장을 경험할 수 있다. 셋째, 시간의 흐름에 따른 사회의 변화를 거울세계를 통해 확인할 수 있다. 넷째, 라이프로깅을 통해 사물의 용도와 주사용자 등 다양한 삶의 방식들을 이해할 수 있다. 이러한 4가지 유형은 사례에 따라서 상호 결합해서 적용할 수 있다. 디지털 시대 역사교육은 단순 정보 전달에 그쳐서는 안된다. 다양한 경험의 확장을 통해 역사상을 제대로 이해할 수 있도록 해야 한다.

Patchwork is a handicraft to put some certain shapes of small cloths together. Historical records of patchwork was discovered in Ancient Egypt as far back as BC 1000. Patchwork has been popular in the England and in around 13-$14^{th}$ century, European spliced little pieces of cloths for cold necessities, which made the handle of patchwork techniques gradually tend to decorative other than utility. Patchwork designs and techniques were taken across the Atlantic to North America with the early settlers in the mid-eighteenth century. In the early years of $20^{th}$ century, owing to the continuous technological advances, woman got more job opportunities that made patchwork technologies withered. Patchwork art continually evolved on the basis of historical and cultural factors to new styles, the famous Hawaiian, Stained Glass, Mola, Celtic, Victoria, Seminole and many other patchwork styles like that perfect embodied different art and cultures of different nations in different times.

Fluid-dynamic design of fluid machinery had heavily relied on empiricism and experimental observations for many years. Since 1980s, thanks to the advancements in Computational Fluid Dynamics (CFD), a variety of flow physics have been revealed. The contribution by CFD is indispensable; however, the challenge is required not only on the advancements in CFD technologies but also innovation of "design (optimization) technologies" because of the complex interactions between 3-D flow fields and the complex 3-D flow passage configurations, etc. This paper presents historical perspective on fluid machinery flow optimization in an industry with some messages for the future.

Statistical analysis of occupational accidents plays an important role in establishing measures against accidents and for evaluating safety performance in work places. This research work, numerous numbers of research work have been conducted, which attemped to verify the existence of !he concept of "accident proneness" Also researches have been developed in the fields of systems safety analysis and risk analysis to analyze the characteristics of occupational accidents. This paper presents a brief historical review of these research activities with particular emphasis on the statistical analysis of occupational accidents. Based on this review, further development needs in relation to the statistical research on the occupational accidents in the near future are discussed.discussed.

As the development of BESS(Battery Energy Storage System), the application of BESS in load frequency control is considered as effective method. So, KEPCO(Korea Electric Power Corporation) have installed about 236MW ESS for GF(Govner Free) function from 2014. In this paper, we implemented Simulink Model for KEPCO GF ESS and analyzed one year historical operation data generated by Simulink model and actually measured frequency data. The operation results were divided into action for maintaining SOC and frequency. In addition, we also analyzed cycle life of GF ESS using two ESS cycle life model. We concluded the ESS cycle life models are not appropriate, because Most of the SOC swing in operation results are below 10%.

Historical background and present status of Korean functional sericulture was reviewed. Five-year expansion projects began in 1962, and produced 41,700 tons of cocoon in 1976 and exported $271 million. However, the number of silkworm rearing households reduced to 59,800 by 1987 from 488,000 in 1976 due to rapid development of the secondary and the tertiary industries with higher labor cost. That's why functional sericulture was developed in Korea. Freeze-dried silkworm powder was found that it lowered the level of blood glucose. Nuedongchunghacho, Paecilomyces tenuipes, was cultured on silkworm larva. Odi, the fruit of mulberry trees, was studied as a new food ingredient. Mulberry tree varieties for improved Odi production were also developed.

The purpose of this study was to analyze the historical development of high-rise buildings-promoting policies in Seoul in terms of modern urban redevelopment. The results of this study were as follows; The maximum height of the buildings has been limited by National codes since 1934. But at the same time, Seoul Metropolitan government had limited the minimum building floors of roadside buildings through local regulations after the Korean War. The high-rise city had been regarded as a means of beautifying Seoul for a long time. However since the 2000s, the minimum height limit for buildings was removed from local regulations and the concept of high-rise restrictions was no longer significant as before.

This research explores the fall of pre-independence Sultanates and its continued political, economic, and cultural influence in post-colonial Indonesia. By using qualitative and historical methods, this paper compares the Sultanates of Mataram in Yogyakarta and Al-Kadrie in Pontianak, which represent different historical paths supporting the struggle for independence during the mid-20th century. Sultan Hamid II of the Al-Kadrie was a supporter of federalism whereas Sultan Hamengkubowono IX of Yogyakarta was an advocate of the republican system. Eventually, Indonesia became a Republic, and the idea of federalism was sidelined, which led to the abolition of sultanates in the rise of the = Indonesian nation-state, except for the Sultanate of Yogyakarta. After the 1998 Reform, the current development of democracy created political opportunities for the Al-Kadrie to reclaim its authority through engagement with various civic organizations. Meanwhile, the Sultanate of Yogyakarta faces internal friction because of succession concerns.

Alcoholic beverages can be viewed as repositories of historical information reflecting agricultural environment, economic and scientific level, religion, literature and art of their country. Korean Alcoholic beverages are based largely on rice, which have been developed in the following order: Takju, Cheongju and distilled spirits, Soju. They are closely related with the development of agriculture and historical levels of science and technology, and thus can be seen as symbolizing economic and political changes as well as rises and declines throughout the culture's history. The present review assessed the past and present flows of Korean alcoholic beverage culture, which has had a significant influence on the mental world of Korean people, based on literature concerning the history of food in Korea. Another focus of the study was a discussion on the future transmission and refining of Korean alcoholic beverage culture, which is undeniably informed by the Korean people's unique imagination and cultural sense.
