The proportional pressure control valve having versatile functions and higher performance is an essential conponent in the open loop controlled rear wheel steering gear of the four wheel steering system in a passenger car. In this study, the authors suggest a new type of load pressure feedback mechanism which can make it easy to change the range of controlled pressure without changing the capacity of solenoid. The concept of suggested mechanism, composed of the pressure chamber with throttles in series, was described. The mathematical model was derived from the rear wheel steering gear consisting of a valve and a cylinder for the purpose of analyzing the valve characteristics. And the programme for computing the characteristic of the valve was developed. Experiments were performed to confirm the performance of the valve and computations were carried out to ascertain the usefulness of the developed programme. The results from computations fairly coincide with those from experiments. And the results from experiments and computations show that the performance of new valve was as good as that of the already developed one and the new valve has advantages such as the easiness of changing the range of controlled pressure and the decrease of power loss at neutral position without the decline of performance.

A 45 year-old man was admitted due to early recurrent parasagittal meningioma with malignant transformation 22 months after initial total tumor resection. The initial surgical specimen was diagnosed as meningotheliomatous meningioma which had no malignant features. Brain magnetic resonance imaging(MRI) showed a recurrent tumor located at the same area of the prior surgery. After second operation, the tumor was pathologically compatible to atypical meningioma. It is rare for a benign meningioma to recur with malignant transformation shortly after surgery. Surgeon should keep in mind that benign meningioma can transform to aggressive tumor in short term and intermittent imaging follow up is needed.

This study, through in-depth interview, tried to do eco-feministic analysis on striking of female taegwondo players within a group. Research subjects were two female players and two male players in male and female taegwondo teams. First, the meaning of striking of female taegwondo players proved to be understood differently by male and female players. It was found that males got the negative image of striking of female taegwondo players. It is impressive that in a male-dominant taegwondo group, males rather than females got the negative perceptions on striking of female taegwondo players. Second, the real cases of striking of female taegwondo players are as follows. When female players were struck not by a senior member, but by a taegwondo leader, they tended to rationalize it as ‘it was my fault’, or ‘I deserve it’. And, the striking of female taegwondo players by a senior member was analyzed with metaphor of step-by-step process of nature destruction in the ecological perspective. Third, eco-feminism of female striking in the view of Nietzsche’s thought and Faucault’s discourse explain the female ‘gender’ as ‘Ubermensch’ to overcome. That is, ‘Ubermensch’ means a new female transcendental class to ‘overcome’ current eco-feministic situation. In addition, through Faucault, ecological power is explained, and females are perceived as an existence of ‘Ubermensch’ who have to escape from power.

This study analyzed physical fitness of the three teams from the 2012 London Olympics in the sport of taekwondo, including team Spain which took the 1st place, team Korea which took the 3rd place, and team Thailand which took the 14th place, via measuring the physical fitness. In order to analyze the body composition and physical fitness of the male taekwondo athletes from the three countries, 14 types of methods of physical fitness measurement were used from the physical fitness measurement evaluation methods, with 27 male taekwondo athletes from the three countries as the subjects of study, and the results of measurement were analyzed per each country. Therefore, statistical verification of the results of measurement were carried out, and the results of the analysis offered the following conclusion. First, there were no differences in the body composition of the male taekwondo athletes from the three countries. To be specific, the analysis result of the body mass index(BMI) of the taekwondo athletes from the three countries showed no difference in the change of body mass between the athletes from Spain, Thailand and Korea and there were also no significant statistical difference between the athletes from the three countries in the height and weight analysis result. Second, the verification result related to physical fitness factor per each country, of male taekwondo athletes from the three countries, showed significant difference in the back muscle strength in the case of strength. In the case of endurance, sit-ups and half-squat jumps displayed significant statistical result. In the area of power, vertical high jump and medicine ball displayed significant result in the case of the three countries. In the result of cardiovascular endurance measurement, harvard step showed significant statistical result between the three countries.

This study aimed to analyze success factors and weakness factors among taekwondo training stadiums and thereby provide assistance in the management of taekwondo gyms based on insights gained from successful cases. The investigation methods used to achieve this research purpose included the qualitative research method of in-depth interviews and successful gyms were analyzed from various perspectives using methods such as attributes factors analysis, 4p’s marketing mix factor analysis and SWOT analysis, selected in accordance with their characteristics. The analysis of gym attributes indicated that the factors that determined success included materials and non-materials services, the degree of openness in the pedagogical approach, transparency in the management of training tuition fees secured by means of the direct participation of the trainees’ parents, the partial return of fees to trainee members, and positive facilities. The 4p’s marketing mix factor analysis found that successful gym were those that increased the satisfaction of the trainees and their parents through the systemically interrelated effects of location, program contents, fee prices, facilities and promotional advertisements. The SWOT analysis demonstrated that the educational program, gym trainee management, gym operation, prioritization of customers satisfaction and management mentality constituted the strength factors, while locational conditions, lack in martial arts aptitudes, decentralization of operations, lack in education time for trainees and lack in proper taekwondo characteristics were weakness factors. In additions, future-oriented gyms were observant of sustained interaction with regional growth to identify opportunities for gym branching and emphasized educational value for consumers, while introducing the latest educational programs to not only enhance the quality of education but also improve communication with parents, utilizing communication technologies to achieve success in their trainee recruitment efforts.

Purpose: The aim of this study was to describe the experience of teaching emergency management and cardiopulmonary resuscitation to medical students in Busan. Methods: Study participants were 59 medical students in Busan. An eight-day curriculum in the emergency management and cardiopulmonary resuscitation was developed. They completed all class sessions and two drill/practical examinations taught by our interdisciplinary team from July 21 through 30, 2003. Each class is approximately 2 hours and reading assignments are given at the end of each class. Also included are practical, table-top and team-building exercises. The participants completed self-reported questionnaires for the education. Results: About establishment and environment of the education, respondents answered with `very good were 14%. About overall theoretical lecture, respondents answered with `very helpful were lower than 40%. Especially, favorable evaluation for the medical lectures was lower than that of other lectures. Students generally enjoyed their emergency medicine experience as it is often their first opportunity to assume primary responsibility for patient care. About overall practices, respondents answered with very helpful were higher than 60%. Conclusion: The authors found that medical students prefer opportunities to hone procedural skills than to hear theoretical lectures. Also, medical students are welcome to hear theoretical lectures that consists of emergency management related contents, not academically medical contents. This curriculum should be tailored to fulfill learner s requirements.
