한려해상국립공원 금산 지역의 야생조류 변화를 2010년부터 2013년까지 조사하여 멸종위기야생생물, 우점종, 환경지표종을 분석하였다. 4년 동안 출현한 야생조류는 8목 21과 50종이며, 2013년도에 39종 (397개체)으로 가장 많은 종이 관찰되었다. 멸종위기야생생물은 매, 붉은배새매, 팔색조 3종이었고, 이동성 현황은 텃새가 60%, 여름철새 32%, 겨울철새 4%의 순으로 높은 비율을 나타내었다. 우점종은 박새(9.2%), 직박구리(7.7%), 곤줄박이(7.5%), 흰배지빠귀(5.9%), 붉은머리오목눈이(5.5%), 오목눈이(4.7%), 멧비둘기(4.6%), 큰부리까마귀(4.0%), 어치(3.7%)의 순이였으며, 종다양도지수(H')는 3.409였다. 환경지표종 분석에서 개체수가 증가한 종은 쇠딱다구리, 박새, 딱새, 노랑턱멧새, 흰배지빠귀 5종이었고, 개체수가 감소한 종은 직박구리 1종이었다.

PURPOSES : The purpose of this system (Rear Lighting System) is to provide illumination for the driver to operate the commercial vehicle safely after dark in highway, to increase the conspicuity of the vehicle, and especially be suggesting the finest observable improvement method, depending on color and pattern of rear lighting system of truck for midnight highway traffic. METHODS : Rear lightning system as an improving way for forward commercial vehicles lighting the securing sight from human factors and the surrounding environment in midnight driving. For this one, basic materials were collected from the data analysis about many types of problems, and filed investigation for establishing Driving Simulator. also taking statistic test to human volunteers after finding recognizable distance of them. RESULTS : As a result, color with the highest visuality is amber followed by green-red-blue as in order for all road types. Especially almost no difference is found between red and green, also when the light is turn off, recognizable distances is wide difference compared to turn on the light. One more thing about study per pattern, upper and entire lighting have similar recognizable distances, but under lighting shows short distance with difficulty securing sight from medians. And straight section shows similar recognizable distances. By finding visuality improvement method depending on color and pattern of supplement taillight, it is expected to suggest quantitative judgement standard for introducing regulation and improvement of supplement taillight. CONCLUSIONS : Night time vehicle conspicuity to the rear is provided by rear position lamps. this study is showed that the color of light ramp is not important to be safe driving, most important is to turn on the light, recognizable distances is big different compared to turn off the rear light, so when the drivng dark in highway, have to turn on the light for reducing risk.

In this study, Rebar of SD500, SD600 is applied to the designed or constructed in domestic apartment. Analyzed the variation of the rebar according to the strength of the rebar and the construction cost of the change. Reinforced volume reduction of the apartment building is less than the other. Because, A low wall of rebar reduction is more than 50% of the total. The reason for the previous, Reduction of the quantity of horizontal reinforcement does not appear and Vertical rebar reinforcement than the stress is determined by the placement of rebar in which the upper floor.

Shear test on hollow-core slabs that using board-type lightweight materials is performed. Lightweight materials are positioned in the slabs, it separate into two parts vertically. It is possible that each parts act independently and the concrete columns, in the middle of slab, can resist this action. Thus we have to check horizontal shear force on part-column connection besides vertical shear force. Also effective cross-sectional area shear force which is considered by existing study is checked.

본 연구는 국제경영과 마케팅 분야의 이론을 기반으로 하여 주요 신흥시장인 중국의 소비자 선호에 대해 이론적으로 고찰하고 실증적으로 검증하였다. 특히 기존 국제경영 분야의 연구에서 중국 소비자의 성향을 단일시하는 경향이 있었던 것과 달리, 본 연구에서는 소비자들의 지역적 특성에 의한 차이가 중국시장에 진입하는 기업들의 성과에 영향을 미치고 더 나아가 향후 전략적 의사결정에 활용될 수 있음을 시사하는 이론적 단초를 제공한다. 이러한 맥락에서, 본 논문은 중국의 자동차 시장을 선정하여 인터넷 포럼에 반영된 소형 자동차에 대한 구매의사가 있는 소비자들의 선호구조를 hedonic/utilitarian, cognitive/experiential, independent/interdependent 로 구분하여 살펴보았다. 내용분석기법 (content analysis) 으로 분석한 결과, 지역에 따라 소비자들의 선호구조와 소비성향에 현저한 차이가 있음을 알 수 있었다. 따라서 본 연구는 외국시장에 진출하는 다국적 기업의 전략수립에 있어서 현지시장과 소비자의 선호구조가 중요한 요인으로 고려되어야 함을 시사한다.

In this technology, To improves the performance of deflection of the slab reduces floor impact noise in downstairs without structural work in vulnerable to floor impact noise in Aged Apartment Houses. The finite element analysis results showed the performance improvement of slab when compared with the existing technologies and Predict the result of the excellent affordability and constructability.

In this study, Rebar of SD500, SD600 is applied to the designed or constructed in domestic underground parking. Analyzed the variation of the rebar according to the strength of the rebar and the construction cost of the change. Most of underground parking appear reduction of Rebar ratio. In this case, the load acting on the underground parking garage is large. So, Rebar placing is dominated by element's stress. Therefore, Large amounts material of slabs, beams and foundations are reduced. In case of columns and wall, Ratio of Material reduction is less than former. Because Splice and Anchorage of rebar amounts are increased and Hoop and horizontal rebar amounts are fixed. Percentage of rebar of the column and wall are 15%. So, Showed a less impact on the reduction of total material.

Strength bar has merits in workability improvement, construction time shortening and connection details to be easy. But, lap splice length tends to be longer. In this study, high strength threaded bar will be reviewed whether it is appropriate in domestic standards by KCI concrete structural criteria and propose the mechanical splice.

This research aims to develop parts for Advanced Fuel/Oil Filtering Re- circulation applicable to this kind of regulation proof engines. These parts can play a role of converting traditional air emission type crankcase into recovery type crankcase so that the engine can deal with environmental regulations, which do not allow minimal amount of toxic gas discharge. For the experiment, test method and specially made testing equipment are prepared. The results showed that Oil separation efficiency of the Cyclone type crank case oil separator was higher than one of the partition wall type in bench test and that Emission gas of the cyclone type oil separator was higher than one of the partition wall type in vehicle test.

Recently, a market of architecture is requiring buildings of long spanned structures as most buildings become taller and larger. For being long spanned structures, elements of buildings must be light. As an alternative proposal, various hollow-core slabs and flat plate salbs were developed and used frequently in the inside and outside of the country. But the study of the hollow-core slabs using deck plate and assembly of light weight is the first. In the present study, Flexural and vibration tests were performed on the hollow-core slabs using deck plate and assembly of light weight to investigate the flexural behavior and serviceability. Four test specimens were used for test parameters; one hollow-core slab with an assembly of light weight, and three hollow-core slabs with deck plate and an assembly of light weight. The test parameters also included amount of tension bar and existence of shear reinforcement. The test results showed that the hollow-core slabs with deck plate and an assembly of light weight had a crack of shear, so shear reinforcement must be conducted.

Recently, practical application of high tension bar is attempted. The main object of using high tension bar is strengthening of material property and decreasing of steel amount. If using high tension bar which is not a definite yield strength，according to strain ratio of high tension bar tensile and compressive dominate mode ciearly, there being a possibility dividing becoming difficult. Specially, Providing steel ratio of balanced destruction is very difficult. In this study, high tension bar to apply to flexural member and the behavior experiment bending after one, will consider high tension bar the application possible standard of existing.
