The research of appearance time delay of highest and lower air temperature in a day and diurnal variation of air temperature were carried out and the results are as follow; 1) In respect to diurnal variation of mean temperature. the highest temperature in a day appear at 1500LST and the lowest temperature come out at 0600LST except for autumn. Therefore, it is considered that lowest temperature is observed just before sun rising or immediately after sunset. 2) The reason of appearance time delay of highest temperature is associated with continental degree and oceanic degree. At this point, the farther it is from costal area, the later highest temperature appear. 3) Characteristics of area where the frequency of highest temperature appearance before 1200LST is more than 10 day, is close to coastal line. This is caused by a) land-sea breeze occurrence, b) clear sky under 5.4 cloudiness, c) wet and high humid atmosphere, and d) high percentage of sunshine.

Field Ion Microscopy를 이용한 Tungsten Silicide의 연구

박동수,정찬익,정승민 慶北大學校 自然科學大學 1985 自然科學論文集 Vol.3 No.-

The atomic structure of silicide layers grown on tungsten surface has been studied by a Field Ion Microscopy. Silicide atoms were vapor deposited on the tungsten tip by resistive heating. Tungsten tips were atomically cleaned by means of pulsed field evaporation. The silicide formation has been achieved by electrical resistive heating in the ultra high vacuum chamber. The optium temperature for tungsten silicide formation was found to be around 700 to 750℃ and its composition was WSi_2. The observed FIM images were composed of tetragonal cllb structure. The silicide grew independently on each W{001} plate, which was considered due to the W lattice constant of these planes matches well with that of the basal of the silicide.

연익준,박상찬 충주대학교 2006 한국교통대학교 논문집 Vol.41 No.-

Semi-dry reactor (S.D.R) system is used to evaluate the effect of spray characteristics for the removal of HCl in the flue gases, and in these experiment, the spray direction was co-current with flue gas and the two-fluid external mixing nozzle was used. And the HCl concentration of the treated flue gas was measured by the combustion gas analyzer (TMS system) on stack. In these experiment, we obtained the maximum removal efficiency of HCl in the incineration flue gas was 96% when atomization quantity of lime slurry was 600ℓ/hr and the Ca/Cl ratio was 3.36 and the slurry droplet size proved 24㎛. Also, the temperature of inlet flue gas into semi-dry reactor have to maintain over 300℃ since lower gas temperature can be caused condensing at the next bag filter.

경안천 중심으로 한 하천자연도 평가

김동찬,박익수 경희대학교 디자인연구원 2004 예술· 디자인학연구 Vol.7 No.1

The purpose of this is to evaluate Kyungan Stream Naturalness Index(S.N.I). and to find out stats, problems and opportunities of the Kyungan stream by assessment standard. Assessment standard is mainly based on physical structure of stream environment. The purpose evaluating sectors and elements are physical form and structure restoration of stream. To find out assessment standard of stream naturalness index, conceptual frame of assessment standard has been established, for which four sections, for example, longitudinal section, lateral section, stream bottom structure and water environment, have been selected. Overall stream naturalness index of the Kyungan stream has been distributed at 3rd to 4th grade, and its assessment index accounted for 3.1 to be 3rd grade, and its mode also did 3rd grade. Stream naturalness index of each section was as follows: Longitudinal section index accounted for 3.2 to be 3rd grade, and stream bottom structure index did 3.1 to be 3rd grade, and water environment did 2.6 to be 2nd grade. Analysis of assessment outcome of stream naturalness index has checked status, Problems and opportunities of corresponding stream. Assessment of stream naturalness index of the study provides useful information for restoration of close-to-nature stream, and furthermore has its meaning in checking problems and opportunities of Kyungan stream.

Today, Suwon campus face circulation and open space problem, especially the spaces in front of Gooksugun, Stadium, and Multimedia Center. In order to solve this problem, therefore we need a rational and organic landscape planning. This plan aims to offer an open spaces which is for comfortable activities as well as better campus landscape. This open space will provide a systematic relationship between individual outdoor space.

폐석재와 석분을 사용한 식생블럭 제품 개발

성찬용,류능환,연규석,윤준노,김영익,남기성,노경희,박일순 강원대학교 부설 석재복합신소재 제품연구센터 2002 석재연 논문집 Vol.7 No.-

본 연구는 폐석재와 석분을 사용하여 친환경적인 식생블럭 제품을 개발하기 위하여 폐석재의 입경과 석분의 첨가량을 각각 3종류씩 총 9종류의 식생블럭에 대하여 단위중량, 공극율, 투수량, 압축강도, 쪼갬인장강도, 휨강도, 내산성, 알카리농도에 대하여 구명하였다. 단위중량, 강도, 내산성은 골재의 입경이 작을수록 석분의 혼입량이 많을수록 크게 나타났으며, 공극율과 투수량은 작게 나타났다. 강도는 중성화 처리 유무에 따라 4∼5% 정도의 미소한 차이가 나타났다. 알카리 농도는 중성화 약품처리, 수중용출, 야외폭로 순으로 효과가 크게 나타났으며, 이는 식생블럭의 중성화 방법 선택에 매우 중요한 내용이라 할 수 있다. 또한, 식생상태는 공극율과 골재의 입경이 큰 식생블럭이 생육에 유리한 것으로 나타났다. This study was performed to develop the environment-friendly plantable block and to evaluate unit weight, void ratio, permeability, strength, acid-resistance and value of pH by the change of the grading of waste stone and the addition amount of stone dust. The unit weight, strength, acid-resistance is increased with small size of waste stone with increase of the addition amount of stone dust. But, the void ratio and permeability is decreased. The strength of neutral plantable block is decreased approximately 4-5% than that of the normal plantable block. The decreased effect of pH increased in order to neutral treatment, underwater leaching and field exposure. It is very important contents in neutral method selection of plantable block. Also, the planting state is grown rapidly with increase of the void ratio and of the waste stone size, approximately.

연익준,박상찬 忠州大學校 2005 한국교통대학교 논문집 Vol.40 No.2

This research was performed to investigate the utilization of fly ash as an adsorbent for effective disposal by recycling of fly ash generated from power plant. The adsorption characteristics of this adsorbent was also studied through the analysis of specific surface area, and removal of heavy mctal ions. The specific surface area of the adsorbent added to 10% Na_(2)SO_(4) at 800℃ was about 2.5~4.0 ㎡/g, which was 8~13 times higher than fly ash. The adsorption of activated charcoal and the manufactured adsorbent at 500 Pb^(2+) ㎎/L at pH 3 were 5.29 ㎎/g and 46.5 ㎎/g, respectively. The removal efficiency of the manufactured adsorbent was about 8.8 times as high as that of activated charcoal, but it was lower for Cu and Cd than activated charcoal.
