과민성(過敏性) 대장증후군(大腸症候群)에 대한 문헌적(文獻的) 고찰(考察)
조윤성,정종안,홍광해,정경아,Cho, Yoon-Sung,Jung, Jong-An,Hong, Gwang-Hae,Jeong, Kyoung-Ah 대한한의학방제학회 2006 大韓韓醫學方劑學會誌 Vol.14 No.2
Objective & Methods : Irritable Bowel Syndrome is occurred frequently in daily life. Nevertheless. medical treatment of the Irritable Bowel Syndrome is almost dependent on western cure, but that cure is not effective enough. So we chose the oriental medicine textbook that were dealing with the oriental concept and the treatment of Irritable Bowel Syndrome. we got these results. Results were as follows : 1. Irritable Bowel Syndrome is characterised by recurrent or chronic abdominal pain, with distension, disturbed defecation and psychic problems without organic lesions. 2. The etiology of Irritable Bowel Syndrome include stress. disharmony of liver and spleen, the coldness of spleen and kidney and the lack of qi or yin, etc. 3. The oriental treatments of Irritable Bowel Syndrome are warming spleen and kidney, easing liver and stopping diarrhea. 4. The internal medication of Irritable Bowel Syndrome was the most used 11 times Tongsayobang(痛瀉要方) and 10 times Yijungtang(理中湯). 5. The most many used herb were Atractylodjs macrocephalae rhjzoma(白朮), Gjnseng Radix (人蔘), Cjnnamomj Cortex(肉桂), Polyporus(猪笭), etc.

청영탕(淸營湯)으로 신진장애를 가진 중풍 초기 환자 치험례
조윤성,정은우,김소연,김현식,이상관,Cho, Yoon-Seong,Jung, Eun-Woo,Kim, So-Yeon,Kim, Hyun-Sik,Lee, Sang-Kwan 대한한의학방제학회 2007 大韓韓醫學方劑學會誌 Vol.15 No.2
This study is clinical report for a acute stroke patient who was improved by treatment of a herbal medication. Stroke patients often shows spirit disorder in early stage. However, the cases which applied Onbyung theory are rare. This paper aims to show that Onbyung theory can be effective to acute stroke. We diagnosed the patient as invasion of the yong system by heat(熱入營分), which showed confusion, insomnia, delirium, anxiety, reddened tongue and dry mouth with cracked lip. After administration of Chungyung-tang(淸營湯) in Wen bing Tiao (溫病條辨), the patient showed those symptoms were highly improved. Thus, we concluded that Onbyung Theory can the patient be adapted to improve the symptom of acute stroke.

Because of computational burden and complex topology of substation, a transmission overload relief using circuit-breaker switching was very complex and difficult. However, a on-line algorithm for reducing the overloads in transmission lines has made progress due to the advance of IT technology. This paper describes the methodology for alleviating the overloads in transmission lines by circuit-breaker switching. First, the severe contingency lists and substations were selected from the results of contingency analysis. Then the switch combinations are determined using circuit-breakers of the selected substation. The topology changes are limited to equipment outage, bus split, island split, bus merge and island merge. Finally, the fast screening and full analysis methods are used to analyze the overload in transmission lines. To verify the performance of the proposed methodology, we performed a comprehensive test for both test system and large-scale power systems. The results of these tests showed that the proposed methodology can accurately alleviate the overloads in transmission lines from online data and can be applied to on-line applications.

HMD의 시각적 특성이 VR콘텐츠 인게이지먼트에 미치는 영향
조윤성(Yoon Sung Cho) 한국디자인리서치학회 2023 한국디자인리서치 Vol.8 No.1
오늘날의 현존감 높은 실감미디어에 대한 사용자의 요구 경향 커지고 있다. 신산업 분야로 기대되는 가상현실 효용성은 사용자의 관심과 참여, 몰입의 상호작용 과정을 통해 발생한다. 이에 가상현실 콘텐츠의 성공 여부 판단에 사용자의 경험과 관심을 이끌어 행위를 유발하는 인게이지먼트 개념이 중요하며 효과적인 인게이지먼트 개념의 적용이 반드시 필요한 시점이다. 본 연구는 가상현실 콘텐츠의 인게이지먼트 향상을 위해 HMD의 시각적 특성 요인과 가상현실 콘텐츠의 현존감 특성, 그리고 이에 따른 미디어 인게이지먼트의 관계를 분석하여 효율적인 사용자 경험 디자인 방안을 목적으로 한다. 따라서 선행연구 고찰을 통해 각각의 특성 요인을 도출, 요인 간 관계를 설문/통계 분석을 통해 실시하였다. 그 결과 HMD의 시각적 특성이 가상현실 콘텐츠의 현존감에 높은 영향을 미친다는 것을 결론을 도출하였다. 또한 가상현실 현존감 요인 중 상호작용성 요인, 미디어의 비가시성, 그리고 사건의 현재성 요인이 몰입도와 흥미성, 주목성 등에 큰 영향을 미치는 것으로 분석되었다. 가상현실 기술은 심화되고 있는 실감 미디어 기반서비스의 경쟁 속에서 가상현실 콘텐츠의 인게이지먼트 특성 요인을 적극적으로 활용하여 다양한 미디어와 융합한 가상현실 콘텐츠 발전에 기여하기를 기대한다. There is a growing trend of user demand for highly immersive media that provides a sense of reality. The utility of virtual reality, which is expected to be a promising industry, arises from the interaction process of user interest, participation, and immersion. Therefore, the concept of engagement, which leads to user behavior by eliciting their experiences and interests, is crucial in determining the success of virtual reality content. Effective application of the concept of engagement is necessary at this point. This study aims to analyze the relationship between the visual characteristics of HMD, the sense of reality of virtual reality content, and media engagement to develop efficient user experience design strategies that enhance engagement in virtual reality content. Through a review of previous studies, we derived each characteristic factor and conducted a survey/statistical analysis of the relationships between them. As a result, we concluded that the visual characteristics of HMD have a significant impact on the sense of reality of virtual reality content. Additionally, it was analyzed that interactivity, media invisibility, and current event factors among the factors affecting the sense of reality in virtual reality have a significant impact on immersion, interest, and attention. In the competition of deepening sense of reality-based services, we expect virtual reality technology to actively utilize the engagement factors of virtual reality content and contribute to the development of virtual reality content that integrates various media.

철도 전력관제시스템을 위한 운영자 훈련용 시뮬레이터 설계에 관한 연구
조윤성(Yoon-Sung Cho) 대한전기학회 2015 전기학회논문지 Vol.64 No.11
This paper describes the design methodology of the operator training simulator for power monitor and control system in the railway system. In power system, the purpose of energy management system was to monitor, control, and analyze the performance of generation and transmission system based on H/W and S/W. Network analysis applications provide a clear picture of power system characteristics using state estimation, power flow and short circuit analysis. In this respect, the operator training system in the railway system should be equipped with the methodology of these systems. First, the proposed database structure in the railway system was introduced. Then the overall structure of operator training system based on railway analysis applications was proposed. Finally, a methodology to verify the performance of the developed applications was described.

This paper presents an implementation of the generator protective relay using Real Time Digital Simulator (RTDS) user defined component (UDC) model designed to facilitate the investigation and evaluation of protective relays. The UDC for RTDS is a convenient model that allows user to develop new component models and run them on the RTDS. The developed model has major features related to the development of six models such as distance, frequency, reverse power, volts per ㎐, over voltage, and out-of-step relays. Also, the generator relay models have been used to support and enhance power engineering education at both the undergraduate and graduate levels. The developed model functions are verified and tested by both static test and dynamic test. The simulation results show the capabilities of the developed generator relay using RTDS UDC.
