The numerous Korean church today embraces the technical goal of the invention building the paradigm of the new mission about the Chinese student studying abroads flowed in into the righteousness, to pay attention to the interior of a country China student studying abroads to the oversea missionary work resource voluntarily, the interior of a country. While the mission environment of Korean Chinese student studying abroads is unable to be good, the result which can be obtained through the missionary activity of the missionaries in China field church is very low. If for the missionary judgment of the Korean churches, the focus is adjusted to the Chinese student studying abroads, the long-term mission strategy which creates the social support system and so that the it has been growing in the mutually different cultural area Chinese student studying abroads can adapt well the Chinese student studying abroads to the Korean culture and college life and can minimize the culture shock because of the gospel will be established. The stress removal factor in which the student studying abroads can take the emotional psychological relaxation is grasped and the Christian culture and the faith settlement, that is the gospel, should be made. the various pattern of adjustments show as to Chinese student studying abroads’ right-foot shoot. However, that it is attached when it has to pay attention. Whether it is familiar with the various factorses including the member of the cultural area, living this success popular culture, language, and etc. or not. However, while the existing values according to the socialist identity which they have in the process of doing Korean college life and world view underwent a lot of difficulties in strange Korean cultural adaptation, the stress was experienced. In this condition, when the church community sets the mission direction and strategy, the many-sided effort for the stress relaxation according to the cultural adaptation of the Chinese student studying abroads is required. the strategic access about how approaching from the position in which the Social Support for canceling the stress required for the cultural adaptation for Korean Chinese college life is needed is required. It has the values, of the church the world view and existing paradigm so far, it is not easy to propagate the Chinese student studying abroads. The strategic access to the new paradigm which can be managed with the form of ‘the come mission’ in ‘it visits mission’ paradigm which the church and missionary group had been providing is desperately required. Therefore the mission resource in which many churches can distinguish the various obstacle according toes the Chinese student studying abroad mission and which can overcome this has to be communally created.

The purpose of this study is to examine the activity ratios of global trunk muscles and local trunk muscles in relation to adjustments in the level of task difficulty while performing stability exercises in easily applied bridging lumbar stabilization exercise. Twenty healthy subjects performed bridging lumbar stabilization exercise while the level of task difficulty was plate was used in the same posture for all the exercises. EMG was used to examine the activity ratios of the global muscles and multifidus in relation to the level of task difficulty. Moreover, the activity ratios of the multifidus muscle, the erector spinae and the gluteus maximus muscle were measured. A one-way ANOVA with repeated measures was used, and a Bonferroni correction was conducted (=.05). When the bridging lumbar stabilization exercise were performed at different difficulty levels, the activity of the multifidus muscle, which is a local muscle, was high in all three exercises. Also, compared to low intensity and intermediate intensity exercises, high intensity exercises showed more significant differences (=.05). Among all the muscles, the multifidus showed the highest activity at intermediate intensity. Based on these results, we suggest that in the case of bridging lumbar stabilization exercise, low intensity or intermediate intensity exercises are more suitable and efficient for local muscle stabilization.

Pt nanoparticle catalysts incorporated on RuO2 nanowire support were successfully synthesized and their electrochemical properties, such as methanol electro-oxidation and electrochemically active surface (EAS) area, were demonstrated for direct methanol fuel cells (DMFCs). After fabricating RuO2 nanowire support via an electrospinning method, two different types of incorporated Pt nanoparticle electrocatalysts were prepared using a precipitation method via the reaction with NaBH4 as a reducing agent. One electrocatalyst was 20 wt% Pt/RuO2, and the other was 40 wt% Pt/RuO2. The structural and electrochemical properties of the Pt nanoparticle electrocatalysts incorporated on electrospun RuO2 nanowire support were investigated using a bright field transmission electron microscopy (bright field TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry. The bright field TEM, XRD, and XPS results indicate that Pt nanoparticle electrocatalysts with sizes of approximately 2-4 nm were well incorporated on the electrospun RuO2 nanowire support with a diameter of approximately 50 nm. The cyclic voltammetry results showed that the Pt nanoparticle catalysts incorporated on the electrospun RuO2 nanowire support give superior catalytic activity in the methanol electro-oxidation and a higher electrochemically active surface (EAS) area when compared with the electrospun Pt nanowire electrocatalysts without the RuO2 nanowire support. Therefore, the Pt nanoparticle catalysts incorporated on the electrospun RuO2 nanowire support could be a promising electrode for direct methanol fuel cells (DMFCs).

The purpose of this study was to investigate the effects of a task-oriented approach on weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement in 18 chronic stroke patients. Both groups were received neurodevelopmental treatment for 30 min/day and then the experimental group (=9) followed additional a task-oriented approach (sit-to stand training with controlled environment) and the control group (=9) followed a passive range of motion exercise for 15 min/day, five days/week, for four weeks. Weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement were measured before and after four weeks of training. There was significantly improved weight-bearing distribution of the paretic leg during sit-to-stand movement in the experimental group compared with that of the control group after four weeks of training (p<.05). But electromyographic activities of the quadriceps and the tibialis anterior of the paretic leg were not significantly different (p>.05). Thus, it is necessary to apply a task-oriented approach to improve the weight-bearing distribution of the paretic leg during sit-to-stand movement in chronic stroke patients.

최근 자연공원 내 케이블카 설치에 대한 타당성 여부를 놓고 찬반 그룹 간에 논쟁이 뜨겁다. 본 연구는 인구사회학적 특성 및 방문경험과 자연과의 유대와의 관계, 자연과의 유대와 케이블카 설치로 인한 결과(사회, 경제, 생태적)에 대한 신념 및 케이블카 설치 지지도와의 관계를 조사하였다. 자료수집은 2010년도 9월 중 총 134명의 무등산도립공원 방문객을 대상으로 현지설문조사를 통해 이루어졌다. 자연과의 유대는 Mayer and Frantz(2004)의 "자연과의 유대척도"를 수정한 척도를 이용하여 측정하였다. 자연과의 유대는 요인분석 결과 2개의 요인, 즉 '상호의존적', '독립적' 요인으로 구분되었다. 응답자의 연령, 교육수준, 무등산도립공원 방문횟수 및 무등산 중봉지역 방문횟수가 높아지거나 많아질수록 자연과의 유대가 증가하였다. 자연과의 유대가 높은 응답자가 낮은 응답자에 비하여 케이블카 설치로 인한 부정적 결과에 대한 신념이 컸지만 긍정적 결과에 대한 신념과는 관계가 없었다. 자연과의 유대 수준이 높은 응답자는 낮은 응답자에 비하여 케이블카 설치에 대한 지지도가 낮게 나타났다.

As a starting material, BCP (biphasic calcium phosphate) nano powder was synthesized by a hydrothermal microwave-assisted process. A highly porous BCP scaffold was fabricated by the sponge replica method using 60 ppi (pore per inch) of polyurethane sponge. The BCP scaffold had interconnected pores ranging from 100 μm to 1000 μm, which were similar to natural cancellous bone. To realize the antibacterial property, a microwave-assisted nano Ag spot coating process was used. The morphology and distribution of nano Ag particles were different depending on the coating conditions, such as concentration of the AgNO3 solution, microwave irradiation times, etc. With an increased microwave irradiation time, the amount of coated nano Ag particles increased. The surface of the BCP scaffold was totally covered with nano Ag particles homogeneously at 20 seconds of microwave irradiation time when 0.6 g of AgNO3 was used. With an increased amount of AgNO3 and irradiation time, the size of the coated particles increased. Antibacterial activities of the solution extracted from the Ag-coated BCP scaffold were examined against gram-negative (Escherichia coli) and gram-positive bacteria (Staphylococcus aureus). When 0.6 g of AgNO3 was used for coating the Ag-coated scaffold, it showed higher antibacterial activities than that of the Ag-coated scaffold using 0.8 g of AgNO3.

Domestic SUV were evaluated for rating the ability of seat and head restraints to prevent neck injury in low speed rear-end crashes. The dynamic test criteria are divided into two groups-seat design parameters(Initial evaluation) and test dummy response parameters(Dynamic evaluation). Head restraint designs with initial geometric ratings of “acceptable" or “good" will be tested in a simulated 16 km/h rear impact to assess whether they provide effective dynamic support for the torso, neck and head. In the measurement and rating of static head restraint geometry, the initial static geometric rating of the domestic SUV cars were “good" except the A-car. In the final rating of the seat and head restraints, W-Car was “good", the other cars were “poor". The performance of dynamic test for the most part of the domestic SUV cars were “poor" and it is necessary to improve.

The aim of this study was to investigate the effect of supporting surface instability to trunk and lower extremity muscle activities during bridging exercise combined with core-stabilization exercise. Thirty young healthy adults (15 males and 15 females) voluntarily participated in this study. Each subject was asked to perform bridging exercise combined with core-stabilization exercise on three different supporting surfaces (stable ground surface, the wooden balancing board, and the air cushion). The muscle activities were measured using surface electromyography (EMG) during performing exercise. To test statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. The findings of this study are summarized as follows. (1) There were significant differences in muscle activities on internal oblique, external oblique, gluteus medius, semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius during exercise (p<.05). (2) The biceps femoris and lateral gastrocnemius showed significantly higher muscle activity on the wooden balancing board rather than on the ground, and semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius showed significantly higher muscle activity on the air cushion rather than on the ground (p<.05). Therefore, it is concluded that muscle activities in the trunk and the lower limbs during bridging exercise combined with core-stabilization exercise was affected with instability of supporting surface. Further researches are needed to investigate the long term effect of bridging exercise on muscle activity with patient group.
