The purpose of this study was to analyze the frequency and contents of horticultural activities in 696 individual activities listed in 11 teacher's guidebooks of Nuri Curriculum for 5-year-olds, and to find out the perceptions of horticultural activities in the formal curriculum. The target horticultural activities that were selected were those using natural objects like potted plants, water, wind, soil, stones, etc. as the topic or subject of activities, and those with different topics but are mentioning plants or natural objects as an example at least twice. The 150 selected horticultural activities were classified by life-based theme, activity type, activity domain, and medium. As a result of examining horticultural activities by life-based theme, there were 150 horticultural activities (21.55%): 40 in Spring, Summer, Autumn and Winter (5.75%), 34 in Animals, Plants, and Nature (4.89%), 22 in Environment and Life (3.16%), 19 in Our Country (2.73%), and nine in Our Neighborhood (1.29%), nine in Various Countries of the World (1.29%), four in Health and Safety (0.57%), four in Living tools (0.57%), four in Transportation (0.57%), three in Kindergarten and Friends (0.43%), two in Me and My Family (0.29%; χ²=130.427, p < .001). As a result of examining horticultural activities by activity type, there were 61 free choice activities (40.67%), 80 large and small group activities (53.33%), and nine outdoor play activities (6.00%), indicating that outdoor play was the fewest activity type (χ²=54.040, p < .001). The results of analyzing horticultural activities by activity domain showed that there were 25 in conversation (16.67%), 19 in science (12.50%), 14 in art (9.33%), 14 in cooking (9.33%), 10 in fairy tales (6.00%), nine in music (6.00%), eight in language (5.33%), eight in number operation (5.33%), eight in others (5.33%), six in children's plays (4.0%), six in games (4.0%), four in body and movement (2.67%), three in stacking (2.00%), three in roles (2.00%), three in rhythm (2.00%), two in children's poems (1.33%), two in field experience (1.33%) and one in outside play (0.67%; χ²=87.600, p < .001). As a result of examining the mediums used in the horticultural activities, 46 activities (30.67%) directly used plants as the mediums, 11 activities (7.33%) used soil such as stones, gravel, and earth as the mediums instead of plants, four activities (2.67%) used dry plants such as branches and dry leaves as the mediums, and 89 activities (59.33%) used videos, photos of plants, and pictures of plants as the mediums (χ²=121.307, p < .001).

20세기 이후 과학기술의 급속한 발전에 따라 인간의 자연적, 신체적 한계를 기술을 통해 극복하려는 시도가 점점 가속화된다. 트랜스휴머니즘은 이러한 인간의 기술적 시도를 적극적으로 지지하고 긍정하는 운동이다. 그러나 트랜스휴머니즘의 기술에 대한 낙관적 태도는 이를 통해 인간의 자연적 본성이 파괴되고, 인간의 가치가 심하게 훼손될 수 있다는 반대론자들의 강한 저항에 부딪히게 된다. 트랜스휴머니즘 논란의 초점은 기술이 인간에게 어떠한 의미를 갖느냐는 것이다. 그러나 트랜스휴머니즘의 정확한 이해를 위해서는 우선 기술과 인간이 한데 어우러져 있는 우리의 '생활세계'에 대한 고찰이 선행되어야 한다. 생활세계는 모든 인간의 실천적 활동의 바탕이 되면서 동시에 이의 산물을 그 자체 안에 포괄하는 개방적이고 포용적인 세계이다. 후설에 따르면 생활세계속으로 인간의 산물이 포함되는 과정은 일종의 '친숙화' 과정으로서 이를 통해 특정 이론이나 기술 등은 생활세계 속에서 우리의 삶과 조화로운 결합을 이루면서 동시에 상대화된다. 이러한 기술의 생활세계로의 편입 및 친숙화는 기술의 인간화 과정이며, 인간과 생활세계의 유한성과 조응하는 과정으로도 볼 수 있다. 이런 맥락에서 볼 때, 트랜스휴머니즘적 시도는 생활세계 속의 인간의 자연스러운 실천의 과정으로서 이에 대해 지나치게 우려할 것도 아니지만 또 과도하게 맹신해서도 안 될 것이다.

Structure-typed cultural heritage, objects of preservation are positioned as one of the very important heritage in the nation, and the preservation of prototypical structures become influential in national development and against natural disaster. For this reason, Digital Close Range Photogrammetry has recently been diversely used. Despite its popular use, the measurement has limits that make it unsuitable for photographing precise cultural heritage situated at high mountainous terrain or where people can not approach easily. These high gigantic stone statues are among the preserved structure-typed cultural heritage. In order to supplement the limits, when using the measurement, a camera tripod with +30m, a ladder truck and a shore should be equipped, which means additional equipment leads to it being a waste of cost and time. In this vein, a device was developed in detail, using a RC Helicopter installed with a CCD video camera with ease of control, safety, equipment, carrying, movement and approach, then checked image shot by a wireless modem at real time and considered the economical efficiency without re-photographing. Next, the author digitized the images of the nationally designated structure-typed cultural heritage, used materials on their restoration as the third dimension in order to construct the integrated management-information system for cultural heritage. Through the above processes, this study can provide specific information on 3D images and 3D CAD sections of structured-typed cultural heritage for both the public and specialists on the web. Moreover, it suggests the foundation to restore the damaged cultural heritage in the future by aiming for their effective management and preservation.

LNG선박에서 발생한 기화가스의 처리를 위해 지금까지는 기화가스를 보조연료로 사용하거나 연소시켰지만 선박의 대형화와 디젤엔진의 사용으로 인해 기화가스를 처리할 수 있는 방법이 제한적인 상황이 되었다. 이를 극복하기 위한 방안으로 고안된 재액화공정은 장치비용과 선박의 제한적인 에너지 공급문제 때문에 지금의 형태를 갖게 되었고 3세대 공정까지 기술발전을 이룩했지만 고효율을 위해 계속해서 연구 개발 중이다. 재액화공정의 방식은 크게 Reverse Brayton Cycle System(RBCS)과 Claude Cycle System(CCS)으로 구분된다. 이 연구에서는 두 가지 System을 분석함으로써 이상적인 피드 상태를 도출하고, 장치 설정을 변경하여 재액화 효율을 높이는데 적합한 설정을 결정하기 위해 HYSYS를 사용하였다. 도출된 경과는 고효율 재액화공정의 설계를 위한 자료로 활용이 가능하다.

An experiment was carried out for 12 weeks to study the feeding behaviour, growth and carcass characteristics of cross-bred goats. Nine bucks with an average live weight of $18.02{\pm}0.9kg$ were allocated in a completely randomized block design arrangement, consisting of three feeding regimes and three blocks. The feeding regimes consisted of 100% natural grass (Treatment A), 100% gliricidia leaf (Treatment B) and 100% ficus leaf (Treatment C). Frequency of turning-over and sniffing the feed and duration and frequency of ruminating, defaecating, and urination of goats in treatment B were longer, while duration of masticating and jaw movement of chewing one bolus was shorter than those of goats in treatments C and A (p < 0.05). Furthermore, goats in treatment B gained more live weight, consumed more feed, consumed less water and was more efficient in utilizing the feed than goats in treatments C or A (p < 0.05). The dressing percentage, carcass length and carcass fat of goats in treatment B were higher and their bone percentages were lower than those in treatments C and A (p < 0.05). There is an indication that feeding gliricidia and ficus leaves during the dry season could not only increase the body weight and improve carcass quality of the goat but also save water for household needs.

Due to increase in demand of stable and long pipelines in natural gas industry, wide range of researches are being performed on automation welding to improved welding quality with respect to weld process parameters in real time measurement. In particular, the coupling between the pipe manufacturing process and location of the weld seam, the measured size of the gap that exists in the weld position and the weld angle depending on whether the movement of molten weld. This is due to absence of controlling welding penetration position, depending on the required size of the angle of the setting. In addition, the optimum welding conditions must be considered while selecting, the correlation between these variables and the systematic correlation has not yet been identified. Therefore, in most welded pipe root-pass weld solely depends on the experience of workers in relation to secure a stable weld quality. In this study, automation welding system is implemented to select a suitable root-pass STT (Surface Tension Transfer) welding method using the optimal welding conditions. To successfully accomplish this objective, there were various welding conditions used for welding experiment to confirm that the assessment required for construction through the pipe and automatic welding process is proposed to optimize this plan.

PURPOSE: The purpose of this study was to examine the effect of visual control on gait speed and balance in patients with stroke. Static balance and gait speed were investigated with comparison and fixed direction of visual. METHODS: We included twenty-six patients with stroke. Participants were measured static balance while standing on a forceplate with one of 4 different visual direction in front, floor, non-affected side and affected side for 30 seconds. To compare of the gait speed, participants had to walk with one of fixed visual direction. And to compare of gait speed with visual dispersion, gait speed were measured with visual change in left and right, up and down direction every 5m, 2m and 1m intervals. RESULTS: The result of the static balance with fixed visual showed that the affected side and the non-affected side were shown significantly increased sway of total sway length, mediolateral distance, anteroposterior distance, average velocity(p<.05). The gait speed with fixed visual showed that affected side was significantly slower(p<.05). And the gait speed significantly increased as interval of visual dispersion decrease in the sagittal and horizontal plane(p<.05). CONCLUSION: The results from this study showed that the visual direction effected on static balance and the faster visual movement made to increase the gait speed. Therefore the rehabilitation training with visual control may be implemented for stroke patients.

The purpose of this paper is to develop waist coat designs that can be worn in the present day by researching design techniques and traditional waist coat forms shown on Korean patchworks called 'Jokakbo', which was commonly used in our traditional culture. By selecting patchwork as the primary motive in particular. The Bojaki, also known as deungguhli or baeguhli(背巨里), gives off a natural and vibrant color sensation. A new design that could be practically worn with modern clothing was developed by sufficiently reflecting this color sensation as well as the aesthetic quality of its geometric shape. On the basis of theoretical consideration of traditional cloth and vest, total of 7 points were designed and produced. These works contain diverse application of the traditional Bojaki and vest. The design of the Bojaki grants rhythmic sense to the side where diverse colors and formative patterns shown on the cloth can be seen as monotonous. The entire side opening of the traditional waistcoat can cover multiple sizes. Depending on the movement, the front and back naturally spreads. The vest can also be worn in layers or used as a cotton quilt depending on the season. And after minimal design alterations, it will be possible to wear the vest with diverse modern clothing due to its straight line and form.
