This study is an architectural investigation paper which has been investigated for 5 years from 1986 about commoner's traditional houses and village in southwestern island area of Korea. Man has lived in this area form the prehistoric age. But from 13C to 14C and in 16C most of people had left this islands by external invasion (Japan) and from 17C many people have lived in real earnest. This area did not have cultural interchange easily than inland area because of geographical conditions, Therefore, so far, many traditional factors have been handed down and especially, a good many commoner's traditional houses exist. The time of builging of these houses is mainly 19C and building shape of those days remains nearly as it is. About 450 houses have been investigated for 5 years. The composition of the houses is composed of Anchae (a centeral house), Sarangchae (an attached house of anchae) and Chukganchae (It has rest room and stores barnyard manure). Somtimes, Sarangchae was ommitted according to the circumstance of the house. Generally, the form of arrangement of house is divided into two shapes; One is 'ㅡ'shape which has only Anchae and the other is 'ㄱ' shape which has Anchae and Sarangchae. In the scale of the house, Anchae averages $41m^2$ and Sarangchae averages $27m^2$.

Waterlogging and unintended lake formation become the main problem in some parts of the world. Starting from 1989, the waterlogging problem was observed in the farmland of the Jarso community of Konso Woreda adjacent to the Segen River in Ethiopia. Therefore, the objectives are determining the extent and causes of unintended lake formation using GIS/RS in addition to a preliminary field survey to mitigate the problem. The analysis of satellite images revealed that over the years invasion of the irrigable land by unwanted water had increased, as, in 1989, the size of the wetland area was about 8 Km²; in 2000 the size of the un-intended lake was only 8.23 ㎢. Alarmingly the size of the lake increased to 19.68 Km² in 2014. Silting up of Weir and changing the flow of River Segen and Human Intervention and changing the natural flow of River Yanda were the main causes of this unwanted prolonged water-logging. The ecological and social environment has been degrading as the people of the waterlogged area have been experiencing some settlement and losing their land. Another problem encountered was flooding from River Barka and invasion of the farmland. Sediment control best management practices (BMPs) i.e, Removal of sediment, providing sandbags and well-scheduled maintenance; Changing the junction point of Yanda and Segen River were suggested for the long-term and short term possible remedial measures. Gabion retaining wall on the bank of the Segen River to the face of Barka River was suggested to protect the farmland from flooding.

It follows in quality and sewage exclusion method of the investigation objective sector and the Combined Sewer Overflows which is suitable in regional characteristics and the confluence area against the rainfall initially a flow and the medulla and measurement - it analyzes the initial rainfall outflow possibility control plan which is suitable in the domestic actual condition and it proposes the monitor ring plan for the long-term flow and pollution load data accumulation. From the research which it sees the Infiltration water/Influent water and CSOs investigation it passes by the phase of hazard chain and Namwon right time 4 it does not hold reverse under selecting, Measurement it used the hazard automatic flow joint seal Sigma 910 machine and in case 15 minute interval of the I/I, it measured a flow at case 5, 15 minute standing of the CSOs. The water quality investigation for the water leakage investigation of the I/I and the sewage from the point which is identical with flow measurement during on-the-spot inspection duration against 6 items which include the BOD sampling and an analysis, when the rainfall analysis for CSOs fundamental investigation analyzed against 18 items which include the BOD sampling. Consequently, for the optimum interpretation invasion water / inflow water of the this investigation area day average the lowest flow - water quality assessment veterinarian optimum interpretation hazard average per day - lowest flow - it averages a medulla evaluation law department one lowest flow evaluation technique and it selects, it presentation collectively from here it gets, position result with base flow analysis of invasion water / inflow water.

Purpose: To determine the prognostic role of muscle area and muscle radiation attenuation in the erector spinae (ES) and multifidus (MF) muscles in patients undergoing gastrectomy. Methods: Patients with stage I-III gastric cancer undergoing gastrectomy were retrospectively enrolled in this study. Clinicopathologic characteristics were collected and analyzed. Both paraspinal muscle index of ES/MF muscles (PMI_EM) and paraspinal muscle radiation attenuation in the same muscles (PMRA_EM) were analyzed at the 3rd lumbar level using axial computed tomographic images. Cox regression analysis was applied to estimate overall survival (OS) and disease-free survival (DFS). Results: There was only a weak correlation between PMI_EM and PMRA_EM (r= 0.28). Multivariate Cox regression revealed that PMRA_EM, but not PMI_EM, was an important determinant of survival. PMRA_EM along with age, tumor-node-metastasis (TNM) stage, perineural invasion, and serum albumin level were significant determinants of both OS and DFS that constituted Model 1. Harrell's concordance index and integrated area under receiver operating characteristic curve were greater for Model 1 than for Model 2 (consisting of the same covariates as Model 1 except PMRA_EM) or Model 3 (consisting of only TNM stage). Conclusion: PMRA_EM, but not PMIEM, was an important determinant of survival. Because there was only a weak correlation between PMI_EM and PMRA_EM in this study, it was presumed that they were mutually exclusive. Model 1 consisting of age, TNM stage, perineural invasion, serum albumin level, and PMRA_EM was greater than nested models (i.e., Model 2 or Model 3) in predicting survival outcomes.

호안 보강 (armoring)은 하천, 호수 및 저수지의 호안 침식을 방지하기 위하여 일반적으로 사용하는 공학적 기법이다. 호안 보강은 육역-수역 경계부를 변경하고, 호안 근처의 지형, 수문, 퇴적물 조성 및 수질을 변화시켜서 호안 식생에 영향을 미친다. 본 연구에서는 대형 저수지인 의암호의 육역-수역 경계부에서 인위 교란이 호안 식생의 군집 구조와 분포에 미치는 영향을 파악하고자 하였다. 의암호의 호안선은 60% 이상이 콘크리트 옹벽, 사석, 돌망태로 보강되어 있었다. 탈경향대응 분석 (DCA)의 결과에 의하면 보강에 의하여 바뀌어진 호안의 식생 구조가 수생식물 우점 생태계에서 습생식물 우점 생태계로 변화하였다. 호안 보강은 육역-수역 경계부에서 점진적 연속성을 파괴하였고 외래식물의 생물침입을 초래하였다. 2010부터 2013년까지 호안 식생의 분포 면적은 수생식물은 감소하였고 습생식물은 증가하였다. 결론적으로 의암호에서 보강, 도로 건설, 휴양 등과 같은 인간 교란은 호안 식생에서 육역화, 횡단 연속성의 상실, 생물침입을 초래하였다. 그러므로 호안 생태계의 특이성을 보전하기 위하여 호안 수생식물 식생대을 확대할 수 있도록 호안 보강 구조물을 철거하거나 재조성하여야 할 것으로 생각된다.

본 연구는 화엄늪 습지보호지역에서 식생의 공간적 분포특성을 파악하고 올바른 식생학적 보전 및 복원 방안을 제시하고자 시행하였다. 식생자료는 2008년과 2013년에 Braun-Branquet의 방법을 적용하여 총 117종(미동정종 포함)의 식물종이 포함된 29개가 획득되었다. 식물군락은 총 8개로 구분되었으며, 수분조건에 따라 건생형(신갈나무-애기감둥사초군락, 산철쭉군락-전형하위군락, 참억새하위군락, 미역줄나무군락)과 습생형(진퍼리새군락-전형하위군락, 왕미꾸리꽝이하위군락, 참억새하위군락, 바늘골-끈끈이주걱군락)으로 나누어졌다. 습생입지에 발달하는 습생형은 습지보호지역 내에서 보호의 핵심 대상으로 습지의 함몰된 공간 또는 물골 주변에 주로 발달하였다. 면적은 습생형이 전체의 약 3.8%에 불과하였으며, 습지보호지역 안에서 참억새가 우점하는 건생형이 약 51.5%로 가장 넓게 분포하였다. 습지보호지역 내에 다양한 수목들이 침투해 있었다. 2008년에는 교목성 수종 8종(총 228개체)과 관목성 수종 6종(총 51개체)을 포함하여 총 14종의 침투식물들이 관찰되었으며, 2013년에는 오리나무 2개체가 생육하는 것이 확인되었다. 화엄늪의 지속적인 보전과 관리를 위해서 식생유형, 공간분포 변화 및 침투식물에 대한 지속적인 모니터링, 핵심 완충 전이지역의 구획화 관리 등을 통한 능동적이고 가변적인 설정방안 모색을 제안하였다.

In this paper, we introduced design of intelligent surveillance camera system and typical event processing scenario for urban transit. To analyze video, we studied events that frequently occur in surveillance camera system. Scenario is designed for estimation in the case of seven representative situations(designated area invasion, an object left alone, removed object in designated area, object tracking, loitering and congestion measurement) in urban transit. Our system is optimized for low hardware complexity, real time processing and scenario dependent solution.
