The purpose of this study was to analyze the movements of the lower extremity muscle activities during a taekwondo kick motion called 'Balbutyeo Naeryeochagi', which was administered to players to improve their posture and muscle activity. Eight professional players and Eight amateur players were recruited as the subjects. Kinematic data were collected by EMG equipment, and the rectus femoris, tibialis anterior, biceps femoris, and medial gastrocnemius were measured using this instruments. This study processed the data using the Windows SPSS Ver. 18.0 to get an independent t-test, with the setting, p<.05. During the 'Balbutyeo Naeryeochagi' kick motion, there were small and inconsistent effects on each part. Results indicated that rectus femoris, tibialis anterior between two groups showed significantly difference in P1 and P2. Biceps femoris muscle activity in P2 showed large values in amateur group, and gastrocnemius showed no significantly difference between professional and amateur player during 'Balbutyeo Naeryeochagi' kick motion.

본 연구의 목적은 특정 목적을 가진 제품들의 특성들을 파악하여 디자인 개발시 이러한 특성들을 제품 컨셉 또는 디자인 형태에 응용하고자 함이다. 이를 위해 먼저 실험 대상을 설정하였고, 실험 대상을 선택한 후 실험 대상에 관한 기초 설문과 실험 대상 이미지 분석을 실시하였다. 이후 실험 대상의 디자인과 기능적 요소를 추출하여 코딩하였다. 그리고 실험 대상의 이미지분석 후 얻은 요소와 실험 대상의 요소의 관계를 증명하였으며, 실험 대상의 특성 추출을 위한 설문을 실시하였다. 이러한 실험 프로세스를 거쳐 특정한 제품에 특성들을 추출함으로써 디자인 개발 시 소비자 니즈의 분석이 가능하며, 제품을 이해하는 기초 자료로 사용이 가능하다. 또한 디자이너가 제품을 쉽게 이해하고 디자인 개발 시 컨셉 설정에 큰 기초가 된다. 본 연구의 MP3의 경우 MP3의 이미지 분석 결과 음악성, 확장성, 휴대성, 사용성, 신체 부담감, 인터페이스, 그리고 개성으로 나타났으며, 이들과 각각 연관된 특성들을 찾았다. 이로써 MP3를 디자인할 때 중요 특성들을 제시하였다. 이러한 기초 연구를 통해 보다 효과적인 소비자 니즈 파악이 가능하고, 디자인 기초 학문 발전을 가져올 것이다.

Containers are commonly used as an effective and relatively inexpensive method for transporting goods. Unfortunately, there are often imbalances between the number of import and export containers, and some ports have a surplus of empty containers while others have a deficit. The Empty Container Simulation Game was developed to address these problems. The game is a computer role playing simulation that simulates the distribution of empty containers in order to solve empty container imbalances among ports. An optimal solution is obtained by the computer using linear programming (LP). Upon completion of the game, a player's game results are displayed along with the LP solution. The game interface was designed to provide easy access and operation. This game will serve to provide an easy understanding and planning for empty container management.

Purpose:This phenomenological study was to describe and to understand nurses' experiences of caring for woman with disability during pregnancy and childbirth. Methods: Participants were 13 nurses from 3 hospitals and 2 local clinics in J city, and were selected through snow-balling method. Data were collected two face to face, semi-structured interviews. The researcher used MP3 player and smart phone for recording as well as transcription process. As for the data analysis, Colaizzi's method was applied. Results: Nurses' experiences were structured as four theme clusters: 'Communicating between/among nurses', 'Recognizing pregnancy and childbirth of woman with disability', 'Taking care of woman with disability based on their differences' and 'Reflecting on nursing care for woman with disability'. Conclusion: It seemed that nurses' recognition to woman with disability and her pregnancy and childbirth was related their nursing care for woman with disability.

이 논문에서는 악기 연주를 전혀 못하는 사용자들에게 연주 경험을 가능하도록 해주는 연주체험 기능성 게임을 제안한다. 연주를 어렵게 만드는 선율을 사용자의 연주 제스처에 맞춰 조율해 주는 악보 조정 알고리즘을 사용함으로써 이 게임은 표준 악보에 기반을 둔 음악을 대리하여 연주한다. 이 연주는 사용자가 재현하는 제스처 기호를 에이전트가 해석함으로써 구현되는 것으로 양자 간의 이러한 상호작용을 퍼스의 커뮤니케이션 모델을 통해 이해한다.

비만유전자의 산물인 렙틴은 주로 지방세포에서 생성 분비된다. 렙틴은 뇌 시상하부에 작용하여 식이섭취량을 줄이고 에너지발산을 증가시켜 궁극적으로 체중을 감소시킨다. 따라서 렙틴 또는 렙틴 수용체의 이상은 극도의 대사증후군을 유발한다. 현재까지 렙틴에 관한 연구의 대부분은 사람을 포함한 포유류에서 수행되었다. 렙틴의 생리적 작용은 만복인자뿐만이 아니다. 본고에서는 현재까지 발표된 논문을 중심으로 닭에서 식이섭취, 면역, 지방대사, 번식과 발달, 그리고 스트레스에 관한 렙틴의작용을 검토했다.

Chorioamnionitis is an inflammation in the fetal membranes or placenta. When chorioamnionitis develops, fetal lungs are exposed to inflammatory cytokines and mediators via amniotic fluid. Because inflammation plays a pivotal role in the development of bronchopulmonary dysplasia (BPD), a chronic lung disease of prematurity, fetal lung inflammation induced by chorioamnionitis has been considered to be one of the major pathogenetic factors for BPD. Although there have been a number of studies that demonstrated the relationship between chorioamnionitis and BPD, there are still controversies on this issue. The controversies on the relationship between chorioamnionitis and BPD arise from not-unified definitions of chorioamnionitis and BPD, different study populations, and the proportion of contribution between inflammation and infectious microorganisms. The publication bias also contributes to the controversies. Clinical trials targeting chorioamnionitis or microorganisms that cause chorioamnionitis will answer on the actual relationship between chorioamnionitis and BPD and provide a novel prophylactic strategy against BPD based on that relationship.

In this study, we propose a pseudo golf club which can sense user's swing motion and virtual golf simulation system using the pseudo golf club. The proposed system is a virtual golf simulation system of a complex play type in which a player can enjoy various types of golf play according to the user's taste by providing a play mode for hitting an actual golf ball and a play mode for swinging the pseudo golf club. This virtual golf play system calculates and displays the trajectory of a golf ball by a simulator just like playing a real golf, and suggests suitable swing motion, so it helps users to learn golf easily.

Not much is known about the membrane trafficking of TRPV1, a key player in pain transduction. Rab11-FIP3, which plays a role in various intracellular transportation pathways, has been reported to interact with TRPV1. In this study, in order to examine the role of Rab11-FIP3 in the membrane trafficking of TRPV1, Rab11-FIP3 expression in dorsal root ganglion (DRG) was inhibited using a siRNA technique. Transportation of TRPV1 to membranes was found to decrease when Rab11-FIP3 expression was inhibited, consistent with the results obtained with TRPV1-transfected HEK cells. Taken together, these results indicate that Rab11-FIP3 plays a role in the membrane trafficking of TRPV1.

With the exponential developments of social network, their fundamental role as a medium to spread information, ideas, and influence has gained importance. It can be expressed by the relationships and interactions within a group of individuals. Therefore, some models and researches from various domains have been in response to the influence maximization problem for the effects of "word of mouth" of new products. For example, in reality, more than two related social groups such as commercial companies and service providers exist within the same market issue. Under such a scenario, they called social adversaries competitively try to occupy their market influence against each other. To address the influence maximization (IM) problem between them, we propose a novel IM problem for social adversarial players (IM-SA) which are exploiting the social network attributes to infer the unknown adversary's network configuration. We sophisticatedly define mathematical closed form to demonstrate that the proposed scheme can have a near-optimal solution for a player.
