Purpose: The purpose of this study was to investigate the correlation between the visual perception ability and the static dynamic balance ability in health elderly. Method: The Motor Free Visual Perception Test-Row Score(MVPT-RS) and MVPT-Process Time(MVPT-PT) were used for evaluating the visual perception abilities. Assessment of the balance ability was taken by using Good Balance System. In the assessment using Good Balance System, X, Y coordinate speed, anterior-posterior direction, medial-lateral direction and Velocity Movement(VM) in standing posture when eye open were measured as static balance abilities. Thirty-seven healthy elderly who live in Gwangyang participated in the experiment for 2 months, from October to November 2010. Results: 1. There were statistically significant differences of MVPT-RS, MVPT-PT, NSB-X, NSB-Y, NSB-VM, OLB-X, and OLB-VM based on the gender(p<0.05). 2. The negative correlations of MVPT-RS:NSB-Y(r=-0.354), MVPT-RS:OLB-X(r=-0.4), MVPT-RS: OLB-Y(r=-0.371), but positive correlations of MVPT-PT:DTB-T showed a statistical significance(r=0.45, p<0.05). 3. The positive correlations of NSB-X:NSB-Y(r=0.54), NSB-X: NSB-VM(r=0.848), NSB-Y:NSB-VM(r=0.531), OLB-X:OLB-Y(r=0.876), OLB-X:OLB-VM(r=0.872), and OLB-Y:OLB-VM(r=0.787) showed statistical significances(p<0.05). Conclusion: These results showed that the visual perception ability was correlated with some balance ability in health elderly. Especially the perception test process time(MVPT-PT) has closely related with the DTB-T. The visual perception ability is considered as a factor on the balance ability in health elderly. Further study will focus on the development of improving program of visual perception ability as an improving method of balancing ability in health elderly.

대륙관계 개폐(開閉)에 대한 일본의 주도적 역할과 함의 - 894년 일본의 고립주의 선택을 중심으로 -

장용수 ( Jang Yong-soo ) 한국유교학회 2011 유교사상문화연구 Vol.44 No.-

본 연구는 9세기 일본이 대륙으로부터 스스로 고립을 선택한 이유에 관한 것이다. 당시 견당사 파견 대사인 미치자네가 파견 취소를 청한 상소문에 따르면 당의 쇠퇴와 항해의 위험 때문이라고 한다. 본 연구는 역사적인 기록을 그대로 받아들이기보다 당시의 동아시아의 상황과 일본 내부적인 권력관계를 통해 실체적인 진실에 다가가고자 한다. 연구를 간단히 요약하면, 7세기 천황을 중심으로 한 중앙집권적인 국가의 형태를 발족시킨 일본은 얼마 지나지 않아 천황과 귀족이 대립적인 양상을 보이게 된다. 이런 천황과 헤이안 귀족의 관계는 8세기부터 경쟁이 치열해지다가 9세기 중후반에 이르러서는 귀족이 우위를 점하게 된다. 권력이 셋쇼정치(섭정)를 하던 후지와라 가문의 손에 들어가자 이에 따른 여러 가지 사회현상이 벌어지는데, 그 중에 하나가 사무역 활성화였다. 후지와라가 이전의 신라와 당나라와 행해오던 공무역을 사무역으로 전환함으로써 외국과의 무역에서 나오는 이익을 자신이 차지하려는 것이었다. 이러한 후지와라가를 중심으로 한 귀족들의 욕심이 894년 견당사 파견 중지로 상징되는 고립주의로의 전환을 초래하는 하나의 이유가 된 것으로 보인다. 따라서 일본을 고립주의의 흐름으로 몰아간 세력은 후지와라가를 중심으로 한 귀족 세력이며, 이런 흐름의 고착은 천황이 권위를 보여줄 수 있는 외교권 행사 기회를 봉쇄할 뿐만 아니라 사무역 활성화로 막대한 재물을 축적할 수 있었던 것이다. 이렇게 해서 헤이안 귀족들은 헤이안 시대의 상징인 ‘화려함’을 12세기 새로운 세력이 등장할 때까지 누릴 수 있었던 것이다. This study intends to study Japan's isolation from the Continent of Asia in the 9th century and its implications. According to historical records, Japan decided a diplomatic break with China in 894, because of the downfall of the Tang dynasty and risks of the voyage. But the historical record can not be fully trusted. This study intends to pursue the real reasons considering the various aspects, which are possibly related with the Japan's decision of the isolation policy. This study investigates the political and economic environment of the East Asia from the 8th century to 10th century, and finds that during the 9th century the international relations of East Asia had turned from political concerns into economic ones. Japan's internal power relation between the Japanese Emperor and the aristocratic class had changed. In the 9th century, the forces of aristocracy exceeded the power of the Emperor. But diplomacy was still in the hands of Emperor, even though Fujiwara family had the real power. For Fujiwara family, the diplomatic break with the Continent of Asia provided a means to contain the Emperor and gave him another advantage, which were profits from the private trade. The isolation of Japan from the Continent of Asia caused not only interruption of political relations, but also severance of the official trade, which was the traditional international trade in East Asia. Because of request of Japanese nobles for luxury items, private trade became to be flourished. And the captain of the Fujiwara family, who had the real power, controlled the private trade. He had enough reason to quit the international relationship with the Continent of Asia.

UV 경화 수지의 화학적 기계적 경화특성 분석

장용수(Yong-Soo Jang),김정근(Jeong-Keun Kim),고선호(Sun-Ho Go),곽이구(Lee-Ku Kwac) 한국기계가공학회 2020 한국기계가공학회지 Vol.19 No.6

Currently, Fiber-Reinforced Plastic (FRP) composite materials are used in many industrial fields, owing to their superior stiffness and specific strength compared to metals. However, there are issues with FRP inefficiency, due to low productivity of such materials, environmental problems they pose and long curing times needed. Trying to address these issues, research was conducted towards the development of a FRP composite material with excellent properties and short production time, introducing a curing method using a UV lamp. Four types of composite materials were prepared, cured with catalyst or UV (CZ: Catalyst + ZNT 6345, CR: Catalyst + RF 1001 MV, UVZ: Photoinitiator + ZNT 6345, and UVR: Photoinitiator + RF 1001 MV). Examination of the chemical and mechanical properties of these composites showed that UV-cured materials performed better than the catalyst-cured ones. These results indicate that the production process of FRP composite materials can be simplified by using a UV lamp for curing, resulting in composite materials with the same quality, but reduced production time by about 70% compared to currently used practices. This advancement will contribute greatly to the composite material industry.

In this study, a UV-cured GFRP molding is made using a combination of hand lay-up and resin transfer molding, and its properties are analyzed. The molded plates produced using various vacuum pressures (0mmHg, -450 mmHg, and -760 mmHg) are examined via a comparison of hand lay-up molding and resin transfer molding. Tests are conducted by processing tensile specimens (ASTM D-5083), flexural test specimens (ASTM D-790), and ILSS test specimens (ASTM D-2344) according to each ASTM standard with a molded plate. Similarly, the UV-cured GFRP molding is compared against GFRP using epoxy. It was confirmed that the mechanical strengths of all the specimens increased when the vacuum pressure was increased and when UV curing was applied. This is believed to be because as the vacuum pressure increases, the pores of the cured specimen are removed, thereby reducing defects, and the bonding force between the glass fiber and the resin is stronger than that of the epoxy resin. It is expected that if resin transfer molding methods and UV-cured resins are used for molding GFRP composites in industry, products with better mechanical properties and faster curing time will be produced.

미국 역사인류학의 추이와 동향 : 미국 인류학의 역사 수용과정을 중심으로

장용수(Jang Yong-Soo) 한국역사민속학회 2011 역사민속학 Vol.35 No.-

본 연구는 共時的 관점에 머물렀던 초기 미국인류학이 역사를 받아들이는 과정을 소개하는 데 초점을 맞추고 있다. 19세기 후반부터 진화론적 이론으로 무장한 미국인류학은 래드클리프브라운과 말리노우스키와 같은 구조기능주의자들과 현장을 중시하며 문화 상대주의를 강조한 보아스와 그의 제자들을 거치면서 '이론 만들기'를 외면하는 경향을 보일뿐만 아니라 역사적인 접근마저도 등한시하게 되었다. 20세기 중반까지도 역사는 미국인류학에서 중요하게 받아들여지지 않다가 민족지학 (Ethnohistory)과 역사인류학(Historical anthropology)의 등장으로 인간 이해에 있어서 그 중요성이 부각되었다. 즉, 인간 사회와 문화에 대한 이해에 공시적인 접근방법이 장애를 만났을 때 通時的 방법에 대한 요구가 등장한 것이다. 이에 부흥하듯, 미국인류학에서 역사적인 방법은 사회/문화에 대한 이해에 상당한 공헌을 하게 된다. 민족지학은 한 사회/문화에 대한 단편적인 이해에서 벗어나 전면적인 역사적 재건을 시도한다. 칼맥(Carmack)에 따르면, 민족지학은 역사적 방법을 적극적으로 활용하는 인류학의 한 분야로 주제에 따라 특수한 역사(specific history), 역사적 민족지(historical ethnography), 민속 역사 (folk history)로 나눌 수 있다고 한다. 방법론으로서 민족지학은 그 동안의 인류학적 결과물을 종합하는 작업을 수행한다. 미국에서의 역사인류학(Historical anthropology)은 역사사회학의 성공에 영향을 받은 측면이 있는데, 민족지학과 유사하게 인류학적 성과를 종합하지만 거시적인 관점을 보인다는 것이 민족지학이나 유럽의 역사인류학과 다른 특징이다. 민족지학과 역사인류학 모두 역사적 방법을 위주로 인간 사회/문화 이해를 확장함으로써 인간의 총제적인 이해라는 인류학의 목적에 공헌하였다. This study intends to introduce the process of taking history into the 'anthropology without history' in America. In the late 19th century, American anthropology begins with an evolutionary theory, such as that of Radcliffe-Brown and Malinowski. Boas and his students, historical particularism, have responsibility for leading American anthropologists to field work(participation and observation), neglecting theory building process. Until the mid-20th century, history had not been popular in American anthropology. The appearance of ethnohistory and historical anthropology is the result of realizing importance of history in the understanding of human beings. When a synchronic understanding of human society/culture meets with an obstacle, a diachronic method is in need. Historical method in anthropology contributes our understanding of society/culture to no small degree. Ethnohistory is a historical reconstruction of the society/culture, which has been understood partially. According to Carmack, ethnohistorians study specific history, historical ethnography and folk history, which is classified in accordance with subject matter. As a methodology, ethnohistory is a synthesis of anthropological outcomes. Historical anthropology, influenced by historical sociology, is another synthesis with a large scale perspective. Ethnohistory and historical anthropology render great services to the anthropological aims, the expansion of our understanding of society/culture.

Purpose: With the increasing numbers of foreign residents in Korea, the need for an emergency medical care system for foreign patients seems to be growing. Sometimes, a foreigner admitted to an emergency room is not treated sufficiently due to the absence of insurance, facility in the Korean language, and a guardian. The management of a foreigner with trauma in the ER is difficult due to various problems such as social and economic status. The purpose of this study was to investigate the current management status of foreigners with penetrating wounds in the emergency room. Methods: This study is an analysis of 580 patients that were diagnosed with penetrating wounds in one teaching Hospital from Jan. 1, 2008 to Dec. 31, 2008. We analyzed results according to nationality, alcohol ingestion, intentional or accidental trauma, trauma mechanism, injury severity, management time in the ER, and outcome in the ER. Results: Of the total 580 patients, 486 patients (83.8%) were native Koreans and 94 patients (16.2%) were foreigners. According to the Revised Trauma Score, the average score of native Korean patients was 7.808, and the average score of foreign patients was 7.638. Of native Korean patients, 22.6% had knife wounds while 38.3% of foreign patients did. Of native Korean patients, 17.3% experienced intentional trauma while 33.0% of the foreign patients did. Of native Korean patients, 22.5% had ingested alcohol while 49.4% of the foreigners had. Of native Korean patients, 10.5% were admitted while 7.6% of the foreign patients were. Of native Korean patients, 14.2% were discharged against medical advice (DAMA), while 18.5% of foreign patients were. Of native Korean patients, 1.2% ran away while 8.7% of the foreign patients did. Conclusion: Stabbing was the most common cause of penetrating wounds in foreigner patients in this study. Intentional trauma was more common in foreigners with penetrating wounds than in native Koreans. The severity was higher in foreigners with penetrating wounds than it was in native Koreans, and patients who ran away or were discharged against medical advice were more commonly foreigners with penetrating wounds. Social insurance or policy is needed for the management of foreigners with penetrating wounds. (J Korean Soc Traumatol 2010;23:102-106)

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.
