The purpose of this study is to proviede basic data for designing sports-brassiere by a questionnaire survey about sports-brassieres preferences and physiological wearing test. The results of the survey and the physiological wearing tests on sports-brassieres are as follow; 1. According to the survey, dissatisfied factors on the sports-brassiere are "drooping and vibrating of the breasts". Preferable factors are supporting breasts by stretch and seldom changing its position by motion. The bigger cup-size and more hemispherical-type causes more discontent than flat-type. 2. The shape of breasts is oval, on what ground, horizontal line is longer than vertical. For the cross section of bust line, shirts type.brassiere is more gently curved than cup-brassiere. 3. The feeling of wearing comfort is correlated with bust.up, shield, close adhesion. The vibration of breasts is correlated with covering urea and close adhesion, and the changing band's position by movement, close adhesion. Too much covering area or strain are in inverse correlation of the comfort. 4. The rate of prevention of vibration is 75~80% on superior sports-brassieres, which has broad covering area and excellent close adhesion. adhesion.

PURPOSE: The purpose of the study was to determine the effects of close kinetic chain resistant exercise of lower extremity on the gait with stroke patients. METHODS: The subjects were 50 patients who were diagnosed with cerebrovascular accident. They were randomly assigned either to a close kinetic chain resistant exercise of lower extremity group (study group)(n=25) or open kinetic chain resistant exercise of lower extremity exercise group (control group)(n=25). Gait abilities were measured by using Timed Up & Go (TUG) test, Functional Gait Assessment (FGA) and spatio-temporal gait variable that were velocity, cadence, stride length, double limb support by 3 axises wireless accelerometer and sway angle of center of mass by same instrument. RESULTS: Study group and control group before and after the intervention there were significantly difference in TUG, FGA, spatio-temporal gait variables and sway angle of center of mass (p<.05). There were significantly different between study group and control group for all variables at post-exercise. CONCLUSION: When all is said and done it is expected to be used as a method for the treatment and prevention in the process of rehabilitation of patients with stroke. In its final analysis when applying resistant exercise of lower extremity to stroke patients' gait, close kinetic chain is more effective than open kinetic chain.

In this paper the development of new technique based on the travelling-wave information contained in the post fault voltage and current signals has been presented. To develop fault location methods which can cope with close-up fault and zero-inception angle problems, magnitude of the backward wave has been used. The technique developed can be incorporated in a generalized algorithm for application as a high speed distance scheme. In this way some of the problems and limitations associated with travelling wave schemes are avoided. Verification of the relay operating principles is presented through digital computer numerical simulation using an electromagnetic transient program(EMTP) in conjunction with simulation of the proposed algorithms.

본 논문에서는 다수의 사람이 존재하는 입력영상에서 입술 움직임 정보를 이용한 실시간 화자의 클로즈업(close-up) 시스템을 구현한다. 칼라 CCD 카메라를 통해 입력되는 동영상에서 화자를 검출한 후 입술 움직임 정보를 이용하여 다른 한 대의 카메라로 화자를 클로즈업한다. 구현된 시스템은 얼굴색 정보와 형태 정보를 이용하여 각 사람의 얼굴 및 입술 영역을 검출한 후, 입술 영역 변화량을 이용하여 화자를 검출한다. 검출된 화자를 클로즈업하기 위하여 PTZ(Pan/Tilt/Zoom) 카메라를 사용하였으며, RS-232C 시리얼 포트를 이용하여 카메라를 제어한다. 실험결과 3인 이상의 입력 동영상에서 정확하게 화자를 검출할 수 있으며, 움직이는 화자의 얼굴 트레킹이 가능하다.

The conventional fault location algorithms based on the travelling waves have an inherent problem. In cases of the close-up faults occurring near the relaying point and of the faults having zero degree inception angle of voltage signals, the conventional algorithms can not estimate an accurate fault distance. It is because the shapes of travelling waves are near sinusoidal in those cases. A new method solving this problem is presented in this paper. An FIR(Finite Impulse response) filter which makes high frequency components prominent and makes the power frequency component and dc-offset attenuated is used. With this method, the cross-correlation peak is to be very clear when a close-up fault or a fault having near zero-degree inception angle occurs. The cross-correlation peaks can be clearly distinguished and accurate fault location is practically possible consequently. A series of simulation studies using EMTP(Electromagnetic Transients Program) show that the proposed algorithm can calculate an accurate fault distance having maximum 2% or less error.

This article studied French case, German case, and England case of rail reform in terms of the relationship between rail infrastructure operator and train operator. Among these three cases there are tie relationship between two different operators backed up by laws. In France the relation between RFF, infrastructure operator, and SNCF, train operator is set up by laws. In Germany the infrastructure operator and train operator form a Konzern and two different operators work with close cooperation. In England SRA, a government authority, plans both infrastructure development and rolling stock demand. From these case studies a conclusion results that there should be a institutional device to maintain close relationship between infrastructure operator and train operator.

Objective: An experiment was conducted to determine the effect of reduced energy density of close-up diets on metabolites, lipolysis and gluconeogenesis in cows during the transition period. Methods: Thirty-nine Holstein dry cows were blocked and assigned randomly to three groups, fed a high energy density diet (HD, 1.62 Mcal of net energy for lactation $[NE_L]/kg$ dry matter [DM]), a medium energy density diet (MD, $1.47Mcal\;NE_L/kg\;DM$), or a low energy density diet (LD, $1.30Mcal\;NE_L/kg\;DM$) prepartum; they were fed the same lactation diet to 28 days in milk (DIM). All the cows were housed in a free-stall barn and fed ad libitum. Results: The reduced energy density diets decreased the blood insulin concentration and increased nonesterified fatty acids (NEFA) concentration in the prepartum period (p<0.05). They also increased the concentrations of glucose, insulin and glucagon, and decreased the concentrations of NEFA and ${\beta}-hydroxybutyrate$ during the first 2 weeks of lactation (p<0.05). The plasma urea nitrogen concentration of both prepartum and postpartum was not affected by dietary energy density (p>0.05). The dietary energy density had no effect on mRNA abundance of insulin receptors, leptin and peroxisome proliferator-activated $receptor-{\gamma}$ in adipose tissue, and phosphoenolpyruvate carboxykinase, carnitine palmitoyltransferase-1 and peroxisome proliferator-activated $receptor-{\alpha}$ in liver during the transition period (p>0.05). The HD cows had higher mRNA abundance of hormone-sensitive lipase at 3 DIM compared with the MD cows and LD cows (p = 0.001). The mRNA abundance of hepatic pyruvate carboxy-kinase at 3 DIM tended to be increased by the reduced energy density of the close-up diets (p = 0.08). Conclusion: The reduced energy density diet prepartum was effective in controlling adipose tissue mobilization and improving the capacity of hepatic gluconeogenesis postpartum.

The platform screen door open-close mechanisms at today's subway are divided by "Radio Frequency method" and "Method at entrance perception sensor". In the case of "method at entrance perception sensor", there happen a lot of occasions of malfunctioning that may cause problems in terms of timeliness, swiftness and reliability of train operation and even ends up to train operation stop since the perceiving process is complicated and it is prone to have dust on lenses, position alteration by train vibration, and less reflection light in the case of new train. In this study, we find how to minimize possible problems in terms of maintenance during train operation period, and seek its alternatives in order not only to have no malfunction in perception but also to cause no disturbance in train operation through dealing organically when perceiving door open-close to minimize delay time.
