[PURPOSE] The purpose of this study was to determine the optimal bending stiffness of volleyball shoe soles by using energy return method as a new shoe evaluation method. [METHODS] Nine healthy male college students were recruited for this study, who had previously attended a volleyball class. The running motion at the speed of 4.0±0.4m/sec and the volleyball jumping motion were measured and analyzed by using 3D motion analysis system and a force platform. [RESULTS] The maximal flexion power at each joint was increased as the mid-sole hardness decreased. The maximal extension power was increased as the mid-sole hardness increased. The energy absorption of each joint was increased as the mid-sole hardness was decreased. The energy production was increased as the mid-sole hardness increased. [CONCLUSIONS] Our study suggests that the energy return method may be a reliable biomechanical assessment technique to determine the optimal bending stiffness of volleyball shoes. Future studies with various shoes are warranted for determining the optimal bending stiffness.

전민주,서지연 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.2

Herein, we investigated the effect of metal electrode, gold and silver, on the performance and stability of organic solar cells. Theoretically silver has a favorable position of work function than gold in our device structure which will give us higher open circuit voltage of device than the device with gold electrode. Interestingly, however, we found that there was no significant difference in performance between silver and gold, but there was a significant difference in stability. To understand the effect of metals on PV performance, we studied the morphology changes of organic active layer before/after bias with the analysis method of EIS, GIWAXS and ToF-SIMS etc.

장소의 형성 요인과 랜드스케이프 건축의 관계성 연구-C. N. Schulz의 장소 형성 요인을 중심으로-

전민주,김연정 한국공간디자인학회 2018 한국공간디자인학회논문집 Vol.13 No.1

(Background and Purpose) A factitious environment that arose on the grounds of the mechanistic thought of the Industrial Revolution era precipitated the problems that caused environmental havoc. The disregard towards nature led to the deterioration of both life and fundamental placeness. Ecological architecture emerged as a solution to this situation. This study analyzes cases of landscape architecture that contemplate the incorporation of the environmental element into ecological architecture, and makes several suggestions that could impede the loss of placeness. The present study aims to explore the relationship between the actual formation of a place—which would eventually become the foundation of the place—and the environment itself. For the latter, the analytical process was based on the elements included in Norberg-Schulz’s theory of place formation; taking into account the cosmic, romantic, classical, and complex scenes and how these relate to the principle of necessity. (Method) In this study, we focused on the arguments of academics emphasizing nature-like environments, especially those of Norberg-Schulz, for analysis. According to Norberg-Schulz, the nature belonging to the place and the man-made place are mutually complementary factors, and that the properties of nature are deemed to be of great value in the building process. This means that the factors coming from the environmental context—including nature itself—may have an impact on the formation of that specific place. (Results) From our analysis of the cases, based on an analysis standard, we are in agreement with Schulz: the actual consideration and intervention of the environment itself during the building process, is what aids in adding balance between artificial and natural place. It also conveys the sense of comfort to its visitors, while influencing the area in question both historically and culturally, and thereby assisting in shaping the uniqueness of the place. Moreover, the place that is formed through this process prompts a bond to co-exist between the place and the people, while assisting in the development of the area at the same time. (Conclusions) This research emphasizes the necessity of landscape architecture that delivers the nature-like environmental factor into the future space design field. It proves how the environment is an essential factor in the formation of the placeness concept in artificially built places. It is also evidences that considering the nature-like environment factor adds more diversity to a specific region, which is necessary in the global era and thus adds competitiveness. Consequently, this study has been able to clearly conceptualize the relationship between the natural environment and artificially created ones, and suggests predictions for the directionality of future design and design planning. That is, within that directionality, it made it evident that place formation derives from it. (연구배경 및 목적) 산업혁명 시기 기계론적 사고를 기반으로 등장했던 인위적인 건조 환경은 환경파괴와 자연에 대한 무관심 양산 같은 문제들을 야기하여 삶의 쾌적성 저하는 물론 환경을 통해 생성되던 지역 고유의 장소성을 상실시켰다. 이후 이를 해결하고자 생태건축이라는 패러다임이 대두되었는데, 본 연구는 생태건축 중 환경을 고려하는 랜드스케이프 건축 사례를 분석하여 장소성 상실에 대한 해결방안을 제시하고자 연구를 시작하였다. 이러한 목적에 따라 본 연구자는 C. N. Schulz의 장소 형성 요인 이론에 속한 우주적, 낭만적, 고전적, 복합적 경관을 기준으로 하여 사례들을 분석하는 일련의 과정을 통해 장소성의 근간이 되는 장소의 형성과 환경의 관계성 및 그 필요성을 정리하였다. (연구방법) 본 연구에서는 장소 형성 요인에 대한 이론들 중 자연과 같은 환경을 강조했던 학자들의 견해를 집중하여 살펴보았고, 특히 C. N Schulz의 이론을 중심으로 분석기준을 마련했다. Schulz의 견해에 의하면 장소의 형성 요인에 해당하는 자연과 인공장소는 서로 상호 보완적인 특성을 가지고 있으며, 건조 과정에 있어 자연과 같은 환경적 요인의 개입이 가치가 있다고 한다. 이는 자연을 포함한 환경적인 맥락에서 파생된 요인들이 장소의 형성에 영향을 미친다는 것을 증명하고 있다. (결과) 분석기준을 통해 각 사례들을 분석한 결과, 본 연구자는 Schulz의 견해처럼 건조 과정에 있어 환경에 대한 고려와 개입이 인공 장소와 자연 장소의 균형을 맞추고, 이용자들에게 쾌적성을 제공하며 나아가 역사적, 문화적 맥락에 영향을 미쳐 지역마다의 고유한 장소와 장소성을 형성하는 데에 도움을 주고 있다는 것을 알 수 있었다. 또한 이러한 과정을 통해 형성된 장소성은 궁극적으로 이용자들에게 장소에 대한 지속적인 애착심과 유대감 등을 형성하는데 도움을 주고, 장소가 소속된 지역의 활성화와 발전에도 도움을 준다는 결론을 도출했다. (결론) 본 연구는 향후 공간디자인에 있어 자연과 같은 환경적 맥락을 고려한 랜드스케이프 건축의 필요성을 강조하며, 환경이라는 요인이 인위적으로 조성된 공간에 장소성을 부여하기 위한 필수 요인이라는 것을 보여 준다. 더불어 환경을 고려하여 형성된 장소성은 글로벌 시대 속에서 지역마다의 다양성을 부여해 경쟁력을 갖출 수 있도록 지원해준다는 것을 알 수 있게 해준다. 결과적으로 본 연구는 자연 환경과 인공 장소의 관계성을 명확하게 정립하는 것을 통해 앞으로의 디자인과 설계의 방향을 제언하고, 이러한 방향 속에서 고유한 장소성이 생성된다는 것을 밝힌 데에 연구의 의의가 있다.

Background: Birt-Hogg-Dube (BHD) syndrome is a rare autosomal dominant disorder that is characterized by the presence of skin fibrofolliculomas, pulmonary cysts, and renal tumors. Clinical and radiologic features of BHD are not well defined in Korean. Methods: Clinical data was retrospectively analyzed in 10 patients (8: confirmed by sequencing for FLCN mutations, 2: clinical diagnosis) with BHD diagnosed from 2004 to 2015 at Asan Medical Center. Diagnositic criteria proposed by the European BHD consortium was used for clinical diagnosis. Results: Median follow-up was 52.7 months. Mean age was 40.4±10.9 years and female was 60.0%. All patients had pulmonary cysts, and 6 of them had history of pneumothorax. Skin fibrofolliculomas was detected in 30% and 20% had renal cancer. The average % predicted value of FVC, TLC, and DLCO was 85.6±13.0, 86.9±11.2, and 88.3±20.1 respectively. 5 of 10 patients had positive family history of BHD symptoms such as pneumothorax. High-resolution CT scans (HRCT) showed multiple and bilateral cysts in all patients and basal predominant distribution of cysts was the most common (40%), followed by diffuse (20%) and apical (10%) predomiant types. Conclusions: Our data suggests that Korean patients may have more frequent pneumothorax and lesser skin lesions compared to previous reports. Multiple, bilateral and basal predominant cysts were the most common findings on HRCT.

The purpose of this research is to investigate the identity development process of an athlete in his life history and to understand its constituent elements as well as the interaction of them. One Ssireum player from H Univ. is selected as a subject of study through Ideal Case Selection which is one of Criterion-based Selection methods. The relevant materials are collected by various means such as in-depth interview, participatory observation, documentary study. According to the general procedure of quality analysis, the data can be arranged through transcription and categorical coding process. The methods of inter-members' checking and peer debriefing are put to use in order to verify the reliability and validity of the data and to validate their trustworthiness and refinement. The results of the study are classified by the question of study as below. There are influential elements on the identity formation such as human relationship, group consciousness, role-playing, seniors' attitudes, conventional manners. The relationship between these elements and his own consciousness makes shape his identity, forming his self image directly and indirectly. As one member of an athlete club, the Ssireum player becomes separated from common students in respect of time, space, and group associates, which are determining elements of athlete's identity formation The athlete not only receives his images from without but also substitutes them with his own images and undergoes the process of refinement and accommodation. The kind of trainers, the nature of an athlete group he turns to, and the feature of the role-playing performance are all affecting the identity formation The surrounding circumstances, which include practice establishment, living environment and management of personal behavior, are integral, too. Athlete's self-realization is closely related with the surrounding cultural frame and the discrimination mechanism within it.

테니스화 개발을 위한 런닝 동작과 사이드 스텝 동작시 후족제어와 압력분포 변인 분석

전민주,곽창수 대한운동학회 2012 아시아 운동학 학술지 Vol.14 No.4

[INTRODUCTION] Running and side step are recognized as more important ones than any other motion in a tennis match. The purpose of this study was to provide preliminary data for designing tennis shoes which were effective in not only injury prevention but exercise performance by the analysis of rearfoot control motion and foot pressure distribution pattern on during running and side-step. [METHOD] The subjects of this study were 10 university male tennis players who had experienced no injuries in lower extremities in recent one year. The 3D cinematographic analysis equipment and the foot pressure distribution equipment were used to analyze running and side step motion wearing three kinds of barefoot, domestic and foreign developed tennis shoes. [RESULT] Initial pronation of achilles tendon angle(running and side), initial pronation of rearfoot angle(running) and total angular displacement achilles tendon angle(side) were appeared bigger in barefoot. Initial pronation of rearfoot angle(side), total angular displacement of rearfoot angle(side), take-off achilles tendon angle(side), Torsion angle, Compression angle(side-step excluded) were showed bigger in the domestic tennis shoe. A foreign tennis shoe showed the shortest in the length of a regional contact time, whereas domestic shoe was the longest contact time. Regional maximum force was appeared bigger inmedial region of forefoot during running, whereas medial region of whole foot during side-step. [CONCLUSION] The result of motion analysis showed that barefoot and domestic tennis shoes figured out smaller initial pronation, total pronation and compression angle. The study also pointed out that foreign tennis shoes had some problems in rearfoot control variables, but they had some better variables than domestic ones. The result of foot pressure distribution pattern of male tennis players indicates that the types of motion determine difference slightly in the peak pressure, the time of peak pressure, the length of contact time, the peak force, and the time of peak pressure, and regional impulse. [서론] 테니스 경기 시 running과 side Step 동작은 다른 동작에 비해 매우 빈번하게 나타나고 있다. 본 연구는 테니스 동작시 자주 발생하는 스텝에 대한 후족제어변인과 압력분포변인을 분석하여 상해예방과 운동수행 능력 향상을 위한 과학적인 신발 설계에 대한 기초자료를 제공하는데 있다. [방법] 본 연구의 피험자는 최근 1년 동안 하지 부위에 부상 경험이 전혀 없는 우수 대학 남자 테니스선수 10명을 대상으로 하였다. 본 연구에 동원된 실험장비는 크게 영상분석장비와 압력분포장비 두 가지이며, 분석대상 동작은 테니스 경기에서 발생빈도가 제일 높은 running 및 side Step 2가지 동작이다. 분석대상 신발은 최근에 개발된 국산 1종류, 외국산 1종류, 맨발의 총 3종류이었다. [결과] 초기 아킬레스건각의 변화량(running와 Side)과 초기 후족각(running), 아킬레스건각의 총 각변위(side)는 맨발에서 가장 크게 나타냈다. 초기 후족각(side)과 후족각의 총 각변위(side), 이지 아킬레스건간(side), torsion각, compression각(side제외)은 국산 신발에서 가장 크게 나타냈다. 외국산 신발이 부위별 접지시간의 길이를 가장 짧게 나타냈고 국산 신발이 가장 길게 나타냈다. 부위별 최대 힘은 running 시 전체적으로 전족의 내측에서 가장 크게 나타났다. Side Step시 부위별 최대 힘은 전체적으로 발의 내측이 외측보다 더 크게 나타냈다. [결론] 맨발과 국산화는 초기 회내운동의 변화량과 총 회내운동의 각변위, compression각을 제외하고 대부분 작게 나타낸 반면 외국산 신발은 국산에 비해 좋은 변인도 있지만 몇 가지 후족제어 변인에서 문제점을 나타냈다. 동작의 유형에 따라서 압력분포변인의 부위별 최대압력, 부위별 최대압력이 나타나는 시점, 접지시간의 길이, 최대 힘, 최대 힘이 나타나는 시점, 부위별 충격량 등에 약간의 차이를 나타냈다. 종합적으로 분석해보면 동작의 유형에 따라서 국산 테니스화와 외국산 테니스화 사이에는 많은 변인에서 비슷한 결과를 나타냈으나 차이를 나타내는 부분도 있었다. 훌륭한 테니스화를 개발하기 위해서는 연구결과의 차이점에 대한 원인 분석과 일반 신발개발원칙을 선택적으로 적용하여야 할 것이다.

씨름선수의 정체성 형성에 관한 생애사적 연구

The purpose of this research is to investigate the identity development process of an athlete in his life history and to understand its constituent elements as well as the interaction of them. In the study on the socialization of mountaineers and Rugby players, Donnely and Young(2001) divided the process into four stages; Pre-socialization stage, Selection and recruitment stage, Socialization stage, Acceptance and ostracism stage. One Ssireum player from H Univ. is selected as a subject of study through Ideal Case Selection which is one of Criterion-based Selection methods. The relevant materials are collected by various means such as in-depth interview, participatory observation, documentary study. According to the general procedure of quality analysis, the data can be arranged through transcription and categorical coding process. The methods of inter-members' checking and peer debriefing are put to use in order to verify the reliability and validity of the data and to validate their trustworthiness and refinement. The results of the study are classified by the question of study as below. What is the conditions of identity as a Ssireum player? Through what process does a man build up the identity? The identity formation of a Ssireum player is formed not by an individual and one-way process but by the mutual relationship between the informer and his surrounding culture, and the relationship between him and fellow members. Furthermore, the mode of change is not simple but consistent and active. The identity of a player become established by going through Pre-socialization stage, Selection and recruitment stage, Socialization stage, Acceptance and ostracism stage, respectively. Pre-socialization stage is one within which a man does not yet become a player. Therefor, this stage is less systematic and less organized than the later stages and can be said to be a germinal stage. Selection and recruitment stage is an introductory one in which a player is initiated into a certain culture by way of the encouragement of his teacher. To become a member of an athlete club is to experience the Ssireum practice other than before. Socialization stage is a phase of new role performance and new identifications. A player associates with the other members and experiences consistent athlete practices through all this phase. He adapts himself to the school life in which he determines his aim. He inherits the others experiences and skills from which he forms a new cultural history on his own. The informer of this study underwent the early three stages and their entire features is almost typical. As a senior student, he came to the fourth stage, namely, Acceptance and ostracism stage, in which he tries to escape from the uniform society of the insistent challenges. As the school, he thinks, emphasized the public relations and the actual results, he also considered the school as a means to personal success. Then, only in this last phase, he feels sorry for his stipulation in which he regards himself only as an athlete. He tries ardently to restore the spirit of the student.
