The purpose of this study was to compare the effects of knee joint position sense following local and general load protocols in 25 healthy male subjects. Proprioception of the knee joint was evaluated by measuring absolute angular errors at matching angles before, after and between 2 different types of load protocols. Proprioception tests(on the dominant knee) were performed in which proprioception of the passivepassive reproduced and active-active reproduced knee position was measured. Local load was provided with maximum isokinetic knee extension-flexion on the isokinetic dynamometer(Cybex), and general load was 10 minutes running on a treadmill. Peak torque(knee extension and flexion) and heart rate(beats per minute) was evaluated as an indicator of local and general fatigue during load protocols. The results were as follows: 1. For pasive-pasive reproduced knee position test, significant difference in absolute angular errors after general load protocol was detected compared with that before general load protocol(P<.05), significant difference in absolute angular errors after local load protocol was detected compared with that before local load protocol(P<.05). However, no significant difference in absolute angular errors of general load protocol was detected compared with that of local load protocol (P>.05), no significant difference in absolute angular errors of local load protocol was detected compared with that of general load protocol(P>.05). 2. For active-active reproduced knee position test, significant difference in absolute angular errors after general load protocol was detected compared with that before general load protocol(P<.05), significant difference in absolute angular errors after local load protocol was detected compared with that before local load protocol (P<.05). Also, significant difference in absolute angular errors of general load protocol was detected compared with that of local load protocol(P<.05), significant difference in absolute angular errors of local load protocol was detected compared with that of general load protocol(P<.05). 3. A significant decrease of peak torque of knee extensors and flexors was seen after local load, although heart rate was significantly increased(P<.05). No significant change of peak torque of knee extensors and flexors was seen after general load(P>.05), although heart rate was also significantly increased(P<.05). The previous study revealed that knee proprioception is significantly altered when the muscle mechanoreceptors are dysfunctional due to muscle fatigue, although the joint mechanoreceptors have no significantly effect on knee proprioception when the presence of knee muscle fatigue. However, the results of this study are different from those of the previous study in that muscle weakness of the knee could not be seen after general load. This study shows that general load may diminish motor control by the central nervous system. Proprioceptional decline without muscle weakness of knee after general load suggests a change in the proprioceptional pathway without influence from muscle mechanoreceptors.

Small and medium-sized local airports have suffered from chronic operating deficits due to many factors except for large airports in Incheon, Gimpo, Jeju and Gimhae. These small and medium-sized local airports have currently been degraded to inefficient airports handling the significantly lower airline demand than their carrying capacities. In this context, this study conducted a survey on the actual conditions of the airline demand in small and medium-sized local airports for the last 10 years after the opening of the Korea Train eXpress and investigated the causes and actual conditions of an increase and a decrease in the airline demand. In addition, it analyzed the functionality, convenience and economic feasibility, competition elements in comparison with other means of transportation, and the actual competitive conditions of local airports. It investigated facility improvements through a field visit for local airports and analyzed the performance rate of passenger demands and the use rate of terminal facilities according to a change in the airline demand. This study aimed to provide basic data in the architectural planning field, needed to establish a plan for the airport revitalization of local airports with the results of an analysis on the actual conditions of small and medium-sized local airports.

One of the most useful method for increasing combustion loading of premixed flame is to strengthen the turbulent intensity of unburned mixture. It produces an important information to a design of efficient combustion equipment that analysing microstructure of strong turbulence premixed flame. The flame structure and characteristics are depend on the turbulence of unburned mixture. Therefore, to strengthen the turbulent intensity of unburned mixture make flame scale small and accomplish efficient combustion. We measured the velocity of local flame front movements, local eddy radius and local reaction zone thickness quantitatively with increasing turbulent intensity of unburned mixture. We researched the microstructure of flame using ion currents that react sensitively in the reaction zone. Consequently, the velocity of local flame front movements is depend on the velocity of unburned mixture and local eddy scale is to be small with increasing turbulent intensity. But there is no change in local reaction zone thickness with turbulence.

This paper is intended as an investigation of the deposition characteristics and mass transport flux estimation in the Nakdong estuary. In order to understand the effects of the tidal current circulation which influenced to an estuary terrain change, the seawater circulation calculation by the use of 2D numerical model for the three cases of without riverflow, mean and flood riverflow quantity condition practiced and each sectional net-flux of water quantity between sandbars(so called, dung) estimated. It may be that an estuary terrain change due to the large scale construction and reclamation at the Nakdong estuary influence to the long-time deposition characteristics. by the revim for the old research, we know that the development of the local sandbars has been moved toward the east-side from the west-side estuary area after the construction of the Nakdong river dike, at present the strong-acted location is the Bakhap-dung of the front sea of Tadea. The seawater circulation pattern at this large scale area of tidal flat bring on a change due to the water quantity outflowing from the Nakdong river. Base on the calculated results for the section net-flux of water quantity, we see that the accumulating action very strong at the local sea around Jangjado, Bakhapdung and Tadae for the case of flood riverflow quantity condition, but at the local sea around Jinudo for the another cases. Consequently, it is emphasized that in the Nakdong estuary the main sensitive regions which influenced from the discharge of riverflow were the local sea around Jangjado, Bakhapdung, Tadae and Jinudo.

Conditions of farm crop switching are affected by several important external factors such as agricultural products import opening, policy support, and climate change. Farming environment is always changing; barriers to imports are becoming lower and lower because of FTA and others, and climate change affects a boundary line of cultivation. Those situations give farmers motivation to change crops in order to cope with them. In addition, crop switching has been done in response to the local government measures about purchase of local agricultural products according to the local food and the expansion of organic agricultural products in school meal. Even though the favorable environment toward crop switching has been created, there are not many researches or outcomes regarding crop switching. Only few studies focus on the list of decision-making in crop switching, and locally suitable crop selection is not treated. In order to utilize crop switching as a farm management strategy, the proper frame should be studied and practical researches on application possibility also need. Therefore, study on crop switching is in a timely, proactive manner because farms catch the chance of expansion of school meal by changing crops. This paper applies HERO model used for venture foundation process to crop switching process. Success factors of HERO model are comprised of Habitate, Entrepreneurship, Resource, and Opportunity, and these phased application factors are applied to crop switching process. By doing so, each phase success factor of crop switching can be uncovered. Three farm organizations supplying organic agricultural products to schools are studied in Gyeonggi province. As a result, the stabilization stage cannot be achieved because of the habitate conditions and social conditions with low risk bearing of crop switching and current school meal systems are the main problems to block the diversification of risks. In order to succeed in crop switching, constructing the habitate in local districts or in systems of school meal is more effective than supporting each farm.

The knowledge-based 21st century requires lifelong education for the development of qualification of man's life and self-development. Schools are considered a place of lifelong education due to easy access to human resources as well as facilities. Furthermore, schools need a more multi-functional openness in order to lead lifelong education of the local society. Jeju schools are in the early stages of creating multi-functional facilities to meet to the needs of the knowledge-based 21st century. In order to bring change into the local school s, this needs to be solved. therefore, the purpose of this research is to complement the elements to needed to open schools, project, management, and operation of multi-functional facilities, so that schools can play a role In lifelong education. To achieve this purpose, this research examined programs and the area of lifelong education at schools through investigating documents on the definition of local society and lifelong education, and analyzed the relationship of schools and local society, and public access of schools' facilities. The results of this study are summarized as follows; 1) Comparing to traditional middle and high school facilities, it occurs various types of plane and the area is somewhat expanded in the school with same class size, however, it needs to improve facility standards in its reality to deal with the change of future educational environment actively. 2) Spatial composition of educational facilities should functionally designed considering that the characteristics of design process mood. In facilities arrangement of middle and high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Therefore, it requires an expansion of space size and facilities for the change of school life outside class.

디지털과 정보통신을 기반으로 한 사회 환경 변화는 동시대의 정보와 문화를 자유롭게 교환하고 소비함으로 인해 지역 간의 문화의 격차를 점차 해소하고 있다. 특히 1995년 지방자치단체가 출범한 후 각지방은 중앙정부 의존 방식에서 벗어나 지역의 자원과 인력, 문화를 가지고 지역을 개발하여 자립하려는 지역 간의 무한 경쟁체제에 처해있다. 이러한 경쟁체제하에 지자체는 각각의 문화와 지역성을 내세워 다른 지역과 차별하기 위한 개발전략과 더불어 다양한 이벤트와 홍보활동을 통해 지역의 브랜드화를 추구하고 있다. 지역 간의 브랜드화와 지역의 자생적 경쟁 구도하에 광고환경도 급 변화하고 있으며 이는 광고에 있어 크리에이티브의 변화를 의미한다. 광고의 크리에이티브와 완성도는 신뢰와 호감을 유도함으로 인해 광고의 설득적 기능을 효과적으로 행하게 하는 주요한 요인이 된다. 이러한 요구에 의해 먼저 정부광고가 빠른 속도로 변화하였고 지자체광고의 변화도 이미 시작되었다. 본 연구는 이러한 변화의 시기에 TV광고 현황을 비교분석 하여 효과적인 지자체 TV광고의 크리에이티브 방향을 제시하고자 한다.

지역신문이 처한 복합적 위기 상황에 대해 지역신문발전지원특별법에 의한 공적 지원이 시행되었다. 이 법안의 제정 목적은 지역신문의 발전기반을 조성하는 것에 그치지 않고 궁극적으로 여론 다양성을 보장하여 민주주의를 실현함에 있다. 이 연구에서는 공공재로서의 성격을 가지는 지역신문에 투입된 공적 지원이 제도적 평가와 함께 지역민, 즉 수용자의 여론 다양성 보장에 영향을 미치고 있는지, 또 이러한 공적 지원으로 인해 지역신문의 공익적 가치가 증대되고 있는지 고찰하고자 한다. 이를 위해 이 연구에서는 지역신문의 정기구독자 중 시민단체의 모니터 활동 참여자를 대상으로 심층인터뷰를 진행했다. 지난 3년 동안의 기금 지원에 대한 효과는 기사를 통한 지면의 개선이 가장 컸고 신문사 사원들과 독자들에게서도 인식의 변화가 있었다는 것이다. 기사의 다양성도 증가되었으나 취재비지원에 대해서는 긍정적 평가와 부정적 평가가 공존했고, 대체로 장기적 효과에 대해서는 회의적이었다. 결국 지역의 신문 수용자는 지역신문이 질적인 개선과 함께 여론 다양성 보장을 위해 기금 지원은 필요하나 수용자적 입장에서의 여론 다양성을 보장하는가에 대한 평가를 고려하고 기금 지원의 효율성을 높일 수 있는 방안이 마련돼야 한다는 입장이라 할 수 있다. 지역신문법에 대한 수용자 관점의 평가를 알아보는 것은 매우 중요한 의미를 지니는데, 한국사회에서 언론의 역할, 특히 지역 언론의 역할과 기능에 대한 책임을 지역 수용자가 요구할 수 있다는 것은 민주주의를 성장시킬 수 있는 동력이 되기 때문이다.

Numerical simulations of photochemical air pollution (CBM: Carbon-Bond Mechanisms under a theoretical three-dimensional local wind system are carried to clarify the fundamental characteristics of the effects of local wind on photochemical air pollution. According to the AWS data of Pusan coastal area and KMA, the surface wind of Pusan during summertime showed a very remarkable land and sea breeze circulation. The ozone concentration distribution using local wind model showed that high ozone concentration zone near coastal area moved toward inland In the afternoon. This change implies a sea breeze Increases the ozone concentration, but a land breeze decreases it in Pusan coastal area.
