This study was conducted to analyze the stand structure and growth characteristics along different elevations of Pinus koraiensis natural forests located at mean elevation 1,300 m (site1), 900 m (site2) and 600 m (site3) on Mt. Seorak. Mean DBH and height of P. koraiensis were 25.4 cm and 12.3 m in site1, while that of site2 and 3 were over 40 cm and 20 m, respectively. For this reason, there was 5 times difference of single tree volume between site1 and other sites(p<0.05). Mean ringwidth increment of P. koraiensis was 1.1 mm/yr in site1, 1.5 mm/yr in site2 and 2.6 mm/yr in site3. However, recent growth of ringwidth has increased by 8.6% in site1, whereas site2 and 3 have fallen by approximately 50% over the last 10 years. These results signify that the growth and distribution of natural P. koraiensis are effected by different climatic environment along elevations.

Recently, organizations intend to adopt new information technology for acquiring relative advantages in competitive business environment. Especially, many companies have paid attention to web-based electronic commerce. But research in this area has largely been performed to the operational and technical aspects of web site. Also the World Wide Web(web) has become one of the most widely used information technologies, but research indicates that there are many firm that are still considering whether to establish a web presence. This study examines factors influencing adoption of corporate web site over time. To examine why companies adopt web site, this study regards web site as an innovation and finds out these reason through Innovation Diffusion Theory. Independent variables of this research are composed of innovation characteristics, organizational characteristics and environmental characteristics. By the result of logistic regression analysis, we find that there are significant differences between early adopters and late adopters of web site for three adoption factors : top management support, organization size, environmental uncertainty. These findings confirm the theoretical frame for adoption of corporate web site. Also this study will provide good guidelines to the companies and the vendors in shaping the strategies of IT adoption and IT diffusion respectively.

Spatial distribution characteristics, volume backscattering strength and species composition of midwater trawling catch was analyzed biological and acoustical characteristics of anchovy shoal, using a high resolution echo - sounder at the south region of East sea of Korea. 1) In the survey site A of Lat.35$^{\circ}$55'N, Long.129$^{\circ}$45'E, the anchovy shoal of small to middle size with the horizontal range of 10~25m and large size with the horizontal range of 40~50m were distributed together. However in the survey site B of Lat.35$^{\circ}$38'N, Long.129$^{\circ}$40'E, the anchovy shoal was observed to be mainly small size which about 78% of the detected shoal. Another was that the anchovy shoal with the vertical range of 2~8m occupied about 68.6% in the survey site A and that of 6~12m occupied about 42.5% in the survey site B. The mainly the site A and B were found to be 10~50m super (2), 64.5% and 20~80m super (2), 66%, respectively. 2) The volume backscattering strength in the site A and B were observed to be -44.0~ -28.0dB, respectively. In the site A, the backscattering strength of -40.0~ -30.0dB was analyzed about 41.4%. 3) Most of total anchovy shoal was concentrated in the water layer of 50~100m in depth with 15.3~18.5$^{\circ}C$, 34.0~34.3$\textperthousand$ in the survey site A and 14.2~16.4$^{\circ}C$, 34.1~34.2$\textperthousand$ in the survey site B. 4) Mean total length(TL) and body weight(BW) of anchovy in the survey site A were 9.9cm and 4.4g respectively, with TL-BW relationship of BW=0.0007T$L^3.65$super (3.85). In site B, mean total length(TL) and body weight(BW) were 11.2cm and 8.7g, with TL-BW relationship of BW=0.0023T$L^3.36$.

지진원 상수의 정밀한 결정과 지진재해의 예측에 있어서 결정적인 요인의 하나는 부지증폭 특성에 관한 상세한 정보이다. 한반도 광대역 지진관측소의 부지증폭 특성이 0.2-20 Hz 범위 내에서 주파수의 함수로 추정되었다. 한반도 남부에서 2003년부터 2008년까지 관측된 43개의 지진에 대한 총 1275개의 지진기록이 사용되었다. 지진동 모델의 역산으로부터 추정된 28개소의 관측소에 대한 부지증폭비는 수직대 수평(H/V) 스펙트럼비로부터 얻어진 증폭비와 몇몇 관측소를 제외하고는 대체로 그 값이 일치하는 것이 발견되었다. 이 연구에서 얻어진 주파수별 부지증폭 특성은 어떤 뚜렷한 공간분포를 보이지 않았다. 또한 부지증폭 특성은 기반암 종류보다는 풍화의 정도와 크게 관련이 있는 것으로 나타났다. 주파수별 부지증폭비를 참조하여 28개소의 광대역 관측소를 4개의 그룹으로 나누었고, 그룹별 특징에 대하여 본문에 서술하였다.

이류-확산 국부적 평형흡착모델(convection-dispersion local equilibrium sorption model)과 Two-site 비평형 흡착모델(non-equilibrium sorption model)을 이용하여 철(Fe)의 토양 내 흡착 및 이동특성을 살펴보았다. 회분실험에서는 철의 주입농도를 변화시키면서 시간에 따른 농도변화를 측정함으로써 철의 흡착특성을 선형흡착등온선과 Freundlich 흡착등온선으로 살펴보았으며, 칼럼실험에서는 주입유속, 유기물함량, 철의 농도를 변화시키면서 주입액과 유출액의 철의 농도를 측정하고, CXTFIT 프로그램을 이용하여 two-site 비평형 흡착 모델에 사용된 매개변수(D, R, ${\beta}$, ${\omega}$)를 구하였다. CXTFIT 프로그램에 의해 구하여진 매개변수들을 이용하여 철의 토양 내 이동특성을 살펴보았으며, 철과 같은 흡착성 물질의 이동특성은 two-site 비평형 흡착모델에 의해 예측할 수 있음을 알 수 있었다.

지진원 및 구조물과 지반상호간의 동적 특성을 보다 신뢰성 있게 분석하기 위해 지반의 증폭특성은 반드시 고려되어야 하는 요소이다. 지반증폭 특성을 분석할 때 여러 가지 방법이 제시되어 있으나 본 연구에서는 Nakamura (1989)에 의해 제시된 방법을 적용하였다. 본 방법은 얕은 지반의 상시미동의 표면파 특성을 이해하기 위해 제시되었으나. 최근 S파 및 Coda파 등에 적용되어 지반의 동적인 증폭 특성연구에 많이 이용되고 있으며 본 연구에서 S파 에너지에 적용하여 분석하였다. 최근 국내의 관측소에 관측된 23개의 규모 3.0 이상의 지진으로 부터 관측된 180 여개의 관측된 지반진동 자료를 분석하여 8개 주요 국내 지진관측소 지반의 동적인 증폭특성을 분석하였다. 각각의 지진관측소마다 저진동수, 고진동수 특성 및 관측소 고유의 우월진동수가 서로 상이하여 관측소 고유의 증폭특성을 보여주었다. 본 연구의 결과를 다른 분석방법을 적용하여 얻어진 결과와 비교하면 국내 지반의 동적 특성 및 지반분류 연구에 많은 정보를 줄 수 있다고 사료된다.

The purpose of this study is to understand a architectural characteristics of local church in Virginia, U. S. This study focuses on not only analyzing the worship and service program inherent in the site planning of local church but also introducing worship service space and chancel elements of it in the village of garden area. We surveyed five protestant churches where are located in suburban and rural area outside of Midlothian city in the early August, 2010. I surveyed church building site and worship service space of churches focused on platform design, interviewed the historical background and program of churches with ministers, and corrected annual calender and newsletter. The results of this study are as follows. First, the characteristics of site plan have a comfortable parking lots and site of churchyard(cemetery) with playground that can take an activities out of chapel. The axis of church building follows to front street. Second, worship services keep two types of traditional and comtemporary worship in order to consider of both adult and youth members. The worship hall has a balance of bilateral symmetry. Third, the form of platform is built that is able to perform a music drama and movement of sermon without only one church, GraceLand Church that church building has over fifty years, and they stick to simple traditional type of Chancel that is established by pulpit, table(altar), baptistery(only baptist church), music instruments, and so on.

To assess preliminarily the contamination potential of water resources including groundwater owing to the hydrogeological characteristics of landfill site and the potential impact to humans and animals through contamination of water resources by leachate, "Landfill Site Preliminary Assessment Model(LASPAS)" was contrived. LASPAS could help them proritization of remediation of landfil sites by the convenient and relatively simple evaluation method of landfill site features. LASPAS was designd to aliot numerical ratings to landfill site related factors undermentioned; 1) hydrogeological factors such as hydraulic conductivity of aquifer, thickness of confining layer over aquifer, topographical slope, net recharge, and subsurface containment 2) water resources contamination factors of impacts on receptors such as proximity to drinking water supply, substitutability of drinking water supply, type of use of water resources, known impact on drinking water supply, and flood potential.

Pollution characteristics of leachate and underground soul of the two landfill states were Investigated Domestic wastes were dumped In the two adjacent landfill states. Only small portion of S landifill site was filled with domestic wastes at the first stage of dumping, and most portion of the site was filled with construction wastes. However Y landfill strate was filed with mostly domestic wastes. Higher concentrations of organic pollutants including VOCs were measured In Y landfill site leachate than In S tendon site. Underground souls of the two linam states were analyzed by the two kinds of leaching methods, KEP (Korean Extraction Processl and Acid Digestion. Underground souls of the both landfill states were not polluted by leachates. Underground soils of the two were composed of firie salty material. Thus It Is fecund that fine silty soul layer of the sea shore may be used as a landfillsite.
