The Design manual for adjusting the capacity and LOS of facilities has been shared in urban railways and high-speed railway stations. However, the pattern of urban railways users and those of high-speed railway users are different from each other. For an example, the high-speed railway users tend to carry voluminous luggages and the transportation disadvantaged such as children and the elderlies. Accordingly, we see that the scale of facilities and the station itself should be constructed differently. The transfer facilities in the high-speed railway stations are classified widely into walking assisting facilities and convenient facilities. We invented the concept of PME(Pedestrian Moving Equivalent) and PWE(Pedestrian Waiting Equivalent)for the spatial calculation of those who are with wheeled luggages, back packs, and children to reflect the uniqueness of users in high-speed railway stations. These equivalents have been applied to the design of the facilities to asses the new Capacity and LOS that are users' favored.

The standard weighing raingauges have a capacity limit in measuring the amounts of precipitation. Exceptions are those using a siphon to drain the collected water during observations. To reduce the drain time of the siphon type or to overcome the hassles associated with the manual emptying of the bucket for measuring, the most of weighing gauges use a large bucket for storing of rainwater to be measured. To avoid the above-mentioned adverse requirements, we propose a paired barrel for a weighing raingauge. The paired barrel may improve the accuracy of the weighing raingauges by getting rid of their capacity limit and make the gauges smaller in size and lighter in weight than the conventional ones. We showed its proper function and the feasibility of realization by testing a prototype paired barrel.

본 연구는 중차량이 혼재하고 있는 비신호 교차로(혹은 로타리형 교차로)에서 용량분석을 실시하는 경우 중차량에 대한 용량 보정계수의 도출에 관한 것이다. 1997년과 2000년도 미국도로용량편람(Highway Capacity Manual)의 비신호 교차로의 용량분석방법에 의하면 이 경우 기초 임계간격(Base Critical Cap)과 기초 추종시간(Base Follow-up Time)에 각각 보정을 하여 실제 임계간격과 실제 추종시간을 산출한 뒤에 이를 이용하여 잠재용량(Potential Capacity)을 산출하도록 되어 있다. 그러나, 미국도로용량편람에서 제시된 이 방법을 사용하는 경우 다양한 종류의 중차량에 대한 용량보정이 매우 임의적으로 처리될 뿐만 아니라 그 부정확성으로 인하여 실제 비신호 교차로의 운영분석 및 설계를 담당하는 실무자들에게 많은 어려움을 주게 된다. 따라서 본 연구는 비신호 교차로에 대하여 미국도로용량편람에서 채택하고 있는 접근방법을 개선하여 보다 손쉬운 방법으로 용량을 보정할 수 있는 간단한 보정계수의 산정 공식을 제공하여 이 분야의 발전에 도움을 주고자 한다. 본 연구에서 제시하고 있는 중차량 용량 보정식은 비신호 교차로에 대한 미국도로용량편람의 제시된 공식과는 달리 일반 고속도로의 용량분석시에 사용되는 중차량 보정식과 유사한 형태의 것으로 유도가 되며 이 보정식의 도출과정에서 새로운 개념의 승용차 환산계수(PCU)의 산정식이 소개된다.

Purpose: This study attempts to understand the effect of stabilization exercise of biofeedback scapular on muscle activity and functional evaluation of the upper extremity in stroke patients. Methods: Patients were divided into two groups; a biofeedback scapular stabilization exercise group comprised of 8 patients and a task-oriented training group including another 8 patients, and 30-minute exercise was performed 5 times a week for 8 weeks. Electromyogram was used to measure muscular activity of lower trapezius, deltoid middle, and serratus anterior. Fugl-Meyer Assessment and Manual Function Test were used to evaluate functions of the muscles mentioned. Results: Significant difference was observed in the comparison group before and after exercise in muscular activity of lower trapezius, deltoid middle, and serratus anterior, Fugl-Meyer Assessment, and Manual Function Test. Conclusion: Therefore, we could see that biofeedback scapular stabilization exercise is more effective than task-oriented training in facilitating muscle activation and functional capacity of upper limb.

The purpose of this article was to contribute to the knowledge of physiological and pathological changes of aging skeletal muscles, and of therapic method. By aging there were changes of distribution of muscle fibers, the loss of muscle mass, the loss of the number of muscle fibers, the loss of glycolysis capacity, the decrease of the oxidative enzymes and muscle vascularization in the skeletal muscles. And as a pathological change, the exhaustive maximal exercise increased oxidative stress that led to oxidative damage which were shown to be implicated in promoting aging. The property of intensity and duration exercise is important not only in keeping human health and physical fitness from oxidative stress, but also for the maintenance of well-being and quality of life.

This study was conducted to develop the leveller suitable for power tiller which has been widely used in Korea. Field test was carried out to determine its performance in accordance with the tilt angles of blede, forward velocities , and the length of blade . The results are follows ; 1. Earth moving capacity of the standard leveller was found to be 90~95kg of soil per one swath while working at the 2nd ~4th gears of forward speed. 2. Work performance of model leveller was 2 , 3, 4 times higher than manual operation in distributing additional soil of thickness 6mm , 12 mm and 24 mm on paddyland, respectively. 3. Levelling performance of model leveller on the inclined fields was 7 ~9 times higher than manual operation.

There is no line of demarcation between the shoulder and elbow regions. Pain In the arm may originate at the shoulder with reference downwards or less often at the elbow with reference upwards. Most pains indicated by the patient at the elbow or forearm have a local origin, since at the more distal part of the upper limb the capacity for correct localization is good. Once it is clear that the elbow region is at fault, the joint and the muscles about it are tested by ten movements. 1. Four. Passive extension, flexion, pronation, supination-full range, LOM, painful, painless. 2. Four. Resisted extension, flexion, pronation, supination-strong, weak, painful, painless. 3. Two. Resisted flexion, extension at the wrist-painful, painless. The muscles that perform theses two movements arise from the humeral epicondyles and a lesion in either often causes pain felt at the elbow although the tissuse affected is not functionally a part of the elbow (i. e. Tennis elbow and Golfer's elbow).

Upright positioning of garlic cloves has been considered as an essential process for mechanical planting because positioning affects the quality and yield of garlic production. Due to the geometrical uniqueness and irregularity of garlic cloves in shape, the planting operation has been conducted by manual. Manual planting requires intensive labors and high production cost. The overall Boal of this research was to develop a garlic clove planter which maintains a garlic clone upright. Specific objective was investigating planting condition and physical properties of garlic clove. The results were summarized as fellows : Based on the survey results, a garlic clove planter should have a planting capacity of at least 140 cloves in a pyung (3.3m$^2$) with the row spacing of 140mm and hill spacing of 120mm for a productive cultivation.

This study was conducted to develop a 2 row type band furrow tiller for a walking cultivator. The tillage and weeding operations in the furrow of dry fields has been done manually or chemical herbicide has been applied. The application of herbicide induces soil pollution and manual operation requires heavy labor. This 2-row type implement was developed to substitute this manual operation and to minimize soil pollution. The developed implement was composed of power transmitting device, tilling device, frame and tail wheel. The max. plowing width and depth were 300mm and 180mm, respectively. The revolutions of the hexagonal shaft and the tillage shaft were $227{\sim}376rpm$ and $355{\sim}590rpm$, respectively. The adequate working speed was $0.50{\sim}0.83m/s$ and the field capacity was $0.17{\sim}0.28hr/10a$.

The purpose of this study is to explorer some strategies for implementing successfully the qualify management for public policy (PPQM) in local government. Researchers for reaching at the purpose reviewed a literature on QM (or TQM) and PPQM in chapter II and suggested implementing strategies of local government's PPQM in chapter III. Implement strategies of local government's PPQM have to build a framework, establish an operating system, develop a customized PPQM's manual, and develop a capacity of local government's civil servant for implementing the PPQM and then build an evaluating system on the result of the PPQM's implementation in local government.
