Ministry of Land, Transport and Maritime Affairs(MLTM) has developed an administration system for architectural information management for completing the electronic application organization of the Architectural administrative information. The main purpose of this study is to suggest legislation system improvement for activation of e-AIS(internet Architectural administration Information System). To achieve this purpose, the authors have investigated the problems of current legislation and soliciting forms for civil affairs applicable to the e-AIS. To handle the current problems of the e-AIS legislation system, legislation and various soliciting forms for civil affairs such as building permission, usage approval, temporary building report are refined. In addition, the authors have suggested possible solutions of current legislation and soliciting forms for civil affairs problems by testing various types of building permission service examples.

We studied the relationship between a civil affair occurrence of bad smell and meteorological conditions around Seongseo district for recent 2 years. The results were as follows; (1) The civil affair occurrence days of bad smell were concentrated from May to August. (2) Daily mean temperatures were mostly 20∼28$^{\circ}C$ and daily mean relative humidities were 60∼80%. (3) Wind speeds were mostly less than 2㎧(75%), and wind directions were southerly winds(50%). It was hardly occurred for relatively well-ventilated conditions in cases of wind speeds 2㎧ over. And the Lagrangian particle dispersion model were used to figure out the transport route in a civil affair occurrence days of bad smell. It was found that the south-western winds transported the bad smelling materials from Jungni-dong(the place of source) to the housing complex located along a piedmont district.

본 연구에서는 아산시의 풍기처리구역을 대상으로 건기시 하수발생량 및 농도의 시간적, 공간적 변화를 조사하였다. 또한 주중과 주말의 하수발생 특성을 알아보기 위해 조사기간내 연속측정된 하수발생량을 요일별로 나누어 각각의 하수발생특성을 조사하였다. 조사 결과 주거지역인 풍기처리구역은 상업지역과는 다르게 직장인의 퇴근 후인 저녁시간대에 하수량이 증가하였다가 점차로 감소하여 새벽녘 4시경에 최소가 되는 것으로 조사되었다. 수질농도는 하수의 피크유량이 발생하였을 때 상대적으로 높았고, 최소유량이 발생하는 새벽시간대에 가장 낮은 농도를 나타내는 것으로 조사되었다. 주중과 주말의 하수발생 특성을 보면, 상업지역의 하수발생량은 주중과 주말의 차이가 뚜렷하게 나타나지 않는 반면 주거지역의 하수발생량은 주말에 직장인들이 가정에 머무르는 시간이 많아지면서 하수량이 증가하는 것으로 조사되었다.

본 연구에서는 아산시의 모종처리구역을 대상으로 합류식 하수관거 월류수의 발생특성을 파악하고자 유량 및 오염물질 발생경향, 오염물질별 상관관계 등에 대하여 살펴보았다. 조사 결과, 강우시 월류 발생초기의 오염물질의 농도는 강우에 의한 초기세척현상(First Flush)에 의해 상당히 높게 나타났으며, 강우초기의 높은 오염물질의 농도는 강우에 의해 희석되어 일시적으로 낮아졌다가 높은 강우강도에 의하여 급격히 상승하였으며, 이후 오염물질의 농도는 유량의 감소에 따라 점차적으로 감소하는 것으로 나타났다. 또한 수질항목별 상관계수를 보면, SS와 TP의 상관계수가 가장 크게 나타났으며, COD와 TP, SS와 COD의 순으로 상관계수가 높은 것으로 나타났다.

감천의 지류인 부항천 유역에 조성될 댐 건설로 인한 인공호의 호수내 수질변화를 예측하기 위하여 WASP5 모형을 이용하였다. 모의결과 현재 수준으로 오염부하가 지속될 경우 2011, 2016, 2021년에 대하여 COD 기준으로 2.07mg/L, 1.93mg/L, 1.84mg/L로 각각 감소하는 것으로 예측되었으며 호소 수질기준 2등급 수준으로 나타났다. 따라서, 수질농도를 원하는 수준으로 낮추기 위하여 유역의 수질보존 대책이 이행되어야 하며, 수질보존 대책이 이행되었을 경우는 COD농도는 1.06mg/L로 감소하는 것으로 나타났다.

In the middle -resolution remote sensing, the Ground Sampled Distance(GSD) sensed and sampled by the detector is generally larger than the size of objects(or materials) of interest, in which case several objects are embedded in a single pixel and cannot be detected spatially. This study is intended to solve this problem of a hyperspectral data with high spectral resolution. We examined the detection algorithm, Linear Spectral Mixing Model, and also made a test on the Hyperion data. To find class Endmembers, we applied two methods, Spectral Library and Geometric Model, and compared them with each other.

Stereoscopic viewing is an efficient technique for not only computer vision but also remote sensing applications. Generally, stereo pair obtained at the same time is necessary for 3D viewing, but it is possible to synthesize a stereomate suitable for stereo view with a single image and disparity-map. There have been researches concerning the generation of the synthetic stereomate from remote sensing imagery. However it is hard to find researches concerning the restoration of occlusion in stereomate. In this paper, we generated synthetic stereomates from remote sensing images, focused on the occlusion restoration. In order to figure out proper restoration methods depending on the spatial resolution of remote sensing imagery, we tested several methods including general interpolation and inpainting technique, then evaluated the results.

We propose a novel methodology based on the multiplication function to improve the signal-to-noise ratio (SNR) for vibration detection in a phi optical time-domain reflectometer system (phi-OTDR). The extreme-mean complementary empirical mode decomposition (ECEMD) is designed to break down the original signal into a set of inherent mode functions (IMFs). The multiplication function in terms of selected IMFs is used to determine a vibration's position. By this method, the SNR of a phi-OTDR system is enhanced by several orders of magnitude. Simulations and experiments applying the method to real data prove the validity of the proposed approach.

The civil service examination system is an important part of the history of education in East Asia. In China, the civil service examination system lasted for almost 1,300 years. Through this, each dynasty was able to prevent the concentration of power to the hereditary nobles and to give competent talents an opportunity to rise to an important position in the state. In terms of medical education, in China, doctors have already been selected through tests since the Song Dynasty. However, the actual cases of medical tests currently remaining in each dynasty are very rare. This paper, firstly, examines the implementation method of the medical test during the Qing Dynasty and examines how it influenced the merit rating. and secondly, this paper examines the actual cases of the remaining Qing medical exam questions, in terms of content, related to the medical text "Uijonggeumgam (醫宗金鑑)" and was influenced by the style of the civil service examination at that time.
