      김상엽,윤영제,최원제,Kim, Sang-Yeup,Yoon, Young-Ieoi,Choi, Won-Jye 대한고유수용성신경근촉진법학회 2010 PNF and Movement Vol.8 No.3

      Purpose : The purpose of this study was to investigate effects of kinesio taping of thigh muscle on isokinetic muscular function during closed kinetic chain exercise of lower extremity. Methods : Twenty healthy males were participated in this study. The isokinetic muscular function of closed kinetic chain were measured for peak torque, peak torque % body weight, average power, max rep tot work before and after application of kinesio taping on thigh muscles. Results : At $60^{\circ}/s$ peak force and peak force % body weight were significant increased in both extension(p<0.01) and flexion(p<0.001) after applying kinesio taping. At $180^{\circ}/s$ average power was significant increased in both extension and flexion after applying taping(p<0.001). At $240^{\circ}/s$ max rep tot work was significant increased in both extension(p<0.001) and flexion(p<0.05). Conclusion : This study suggests that application of kinesio taping on thigh muscle was more effective to improve isokinetic muscular function in closed kinetic chain exercise of lower extremity.

      Model of Volume-Delay Formula to Assess Travel Time Savings of Underground Tunnel Roads

      김상엽,최재성,이동민,장태연 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.6

      This article presents the result of conducting a working model of the Volume to Delay Formula (VDF) that will be applied toanalyze the economic feasibility of underground tunnel road projects in Seoul. Without this formula, highway engineers are unable toassess the travel time savings of the underground tunnel road projects, and this troubling situation deters a reasonable progress of thismassive plan. To deal with this problem, the research carried out a field survey study in an existing mountain tunnel to capture thecharacteristics of tunnel traffic flow and conducted a follow-up study to calibrate operational parameters of this tunnel traffic flow. The Golden Section search method was adopted in this purpose and major findings revealed that a reliable VDF could besuccessfully developed based on the analysis of existing mountain tunnel flows. It was also found that traffic volume levels estimatedwith existing VDF’s and the ones estimated with developed VDF’s were much different: a more reasonable volume level wasobserved across all highway links. We thus concluded that the developed VDF’s should be applied to assess travel time savings of theunderground tunnel road projects in Seoul. The study results can be applied successfully to six lane tunnels, but more validationefforts are required for other types of tunnels.

      『故朴榮喆氏寄贈書畵類展觀目錄』을 통해 본 다산(多山) 박영철(朴榮喆, 1879~1939)의 수장활동

      김상엽 국립문화재연구원 2011 헤리티지:역사와 과학 Vol.44 No.4

      The study of the modern art market and distribution differs in its research focus from that of traditional art history, which traces and analyzes the works of master artists, their schools and influence, in that it attempts to approach such issues as art and society, and distribution and consumption of works of art, based on new research methods and perspectives. This paper examines the life and art collection activities of Park Yeong-cheol, considered to be one of the earliest major modern Korean art collectors. He graduated from the Japanese military academy and served as both a solider of the Greater Korean Empire and a high level officer of the Japanese army. After being discharged, he served as Governor of Gangwon-do and then Hamgyeongbuk-do, and after his retirement from public office, he became a leading businessman. He is well-known as a Japanese sympathizer who approved of and advocated for the aggressive colonial policies of the Japanese empire. As a cultural enthusiast and art collector, however, Park Yeong-cheol published the most accurate edition of Yeonamjip, and donated his collection to Geyongseong University at the end of his life, thus providing the foundation for the Seoul National University Museum. All of these activities are highly commendable. His interest in growing his collection of paintings and calligraphies was largely motivated by his love of paintings and Chinese poems,but it also appears to have been the result of his active collaboration with the Japanese government's policy of trying to discover the distinct, non-western characteristics of traditional Eastern art. 근대 미술시장과 유통에 대한 연구는 명품대가 및 그 유파, 영향 등을 추적하고 분석하던 기존 미술사의 연구경향과 달리 미술과 사회, 미술품 유통과 소비 등 새로운 연구방식과 관점으로 접근하고자 하는 시도이다. 이 글에서는 한국 근대의 주요 수장가 가운데 가장 이른 시기의 수장가의 하나로 꼽히는 박영철(1879~1939)의 생애와 수장활동을 살펴보았다. 박영철은 일본 육군사관학교를 졸업한 대한제국의 군인이자 일본군의 고위 장교, 전역 이후에는 강원도 지사, 함경북도 지사 등을 지냈고, 관직 은퇴 이후에는 굴지의 기업인으로 활동하였다. 그는 일제의 침략정책에 호응하고 앞장 선 철저한 친일파로서 잘 알려져 있다. 그러나 문화애호가이자 수장가로서의 박영철은 가장 정확한『연암집』을 간행하였고, 사후에 수장품을 경성제국대학에 기증 하여 서울대학교 박물관의 기초를 마련한 점은 높이 평가할 만하다. 그의 서화수장은 한시와 서화 등을 좋아하고 즐겼던 그의 성정에 의한 바 크지만 동양의 비서구적 원천으로서 전통미술에서 고유의 특성을 찾으려 한 일본의 시책에 적극 협조한 것에 기인한 것으로 보인다.@

      한국인 신생아 음경 길이에 대한 연구

      김상엽,전재성,이상길 대한소아청소년과학회 2008 Clinical and Experimental Pediatrics (CEP) Vol.51 No.9

      Purpose:As modern society has became more open, interest in healthy internal and external growth has increased, including that pertaining to penile length in children. A micropenis is defined as one where penile length is more than 2 SD (standard deviation) below the mean, and it can be traced back to chromosome and endocrine disorders. The authors executed this study to suggest guidelines for the study of the micropenis and standard information for penile length in Korean newborns. Methods:The subjects of this study were 168 male infants between 37 and 42 weeks of gestational age, none of whom had any complications during pregnancy or birth; each had been born in Daegu Fatima Hospital between February and June 2007. Penile length was measured using conventional stretched penile length measurement (CPLM) and syringe methods. Results:Penile length was 3.02±0.25 cm (F=36.467, R2=0.180, P<0.001) when measured with CPLM, and 3.29±0.26 cm (F=9.149, R2=0.052, P<0.001) with the syringe method. There was no statistically significant difference in the penile length of newborn infants as a result of taking measurements with the two methods, and both methods showed significance at 0.631 in terms of Pearson's correlation coefficient, at the level of P=0.01. Conclusion:In this study, penile length tended to be longer when gestational age was longer, and a micropenis can be assumed to be one less than 2.5 cm using CPLM and less than 2.8 cm using the syringe method. In the case of a concealed penis, the syringe method is helpful. When a micropenis is assumed, close observation by outpatient department personnel, and additional endocrine and chromosome studies should be undertaken after sufficiently consulting the parents.

      [특별강연록] 게일(Gail) 허(Huh) 여사의 기증과 그 주변:국외문화재 환수의 의미와 과정에 대한 일고찰

      김상엽 미술사연구회 2024 미술사연구 Vol.0 No.47

      Held at the Gwangju National Museum (GNM) from September 15th to December 10th, 2023, the special exhibition entitled Paintings Loved and Cherished was a resounding success, garnering the attention of both numerous media outlets and a large body of visitors. This special exhibition was held in commemoration of the GNM receiving the donation of Huh Ryun’s Eight-Fold Landscape Screen (Sansudopalpokbyeongpung) and Pine Trees Diptych (Sonamu daeryeon); Kim Jingyu’s Plum Blossom (Mukmae) [part of Seoknong’s Album of Paintings (Seoknonghwawon)]; and Shin Myeongyeon’s Portrait of Su Shi in a Bamboo Hat and Clogs (Dongpaipgeukdo), all of which come from the personal collection of the late Mr. Huh Minsu, a Jindo-born banker. Formerly in the safekeeping of Mr. Huh’s American daughter-in-law Mrs. Gail Ellis Huh, these collected pieces came back to Korea under a donation agreement thanks to the efforts of the Overseas Cultural Heritage Foundation and its U.S. office. Mrs. Huh’s donation was made out of respect for her father-in-law and love for her late husband Huh Gyeongmo, as well as her affection for the city of Jindo and Korean culture at large. Mrs. Huh’s decision rendered possible the repatriation of priceless cultural properties, bringing a great deal of joy to Korea and touching the hearts of many people. We are now charged with the responsibility of continuing to honor and remember Mrs. Huh’s gesture of kindness and good will

      하이퍼바이저 권한의 공격자로부터 안전한 신뢰 실행 환경을 제공하기 위한 부채널 공격 실시간 탐지 기법

      김상엽,김태훈,신영주 한국정보보호학회 2024 정보보호학회논문지 Vol.34 No.5

      The recent increase in public cloud usage has led to various security issues. In response, CPU manufacturers have introduced Trusted Execution Environment (TEE) technology, allowing secure service usage even with potentially untrustworthy cloud service providers. For instance, AMD offers VM-level TEE through SEV(Secure Encrypted Virtualization). However, it has been raised that confidential information can be leaked via page fault-based side-channel attacks on VMs protected by SEV. To address this, this paper proposes a method for real-time detection of such attacks in SEV environments. Nonetheless, since attackers can have hypervisor-level privileges under the SEV threat model, realizing this is challenging. To overcome this, we propose two approaches. First, using VMPL(Virtual Machine Privileged Level) to protect the detection program from untrusted hypervisors. Second, utilizing vPMU(virtual Performance Monitoring Unit) to derive new features for detecting page side-channel attacks. The designed and implemented detection program achieved a 95.38% accuracy in detecting page fault side-channel attacks.
