In order to give back-to-farm residents the stable settlement environment in the rural area, the 'community village' is desirable as the village type and its village planning guideline should be supported as well. The purpose of this study was to develop a guideline for the planning of back-to-farm community village in the living and social environmental aspects, based on the comprehensive comparative analysis about items that field survey and literature suggested. The guideline for the living environment was developed for 6 items; village structure(adequate size, lot, outer space for household), village landscape(allocation, space composition), road system and transportation(parking lot in village, placement of bus stops, village trail, public transportation, road and pedestrian system), common living facilities and common space(number, size, location & placement, plan type, planning type of common facilities), transfer space, individual housing(type, size, planning type). The guideline for the social environment was developed for 3 items; village making and establishment(resident participation type, resident participation tool, residents' construction participation) and resident education in the course of planning, resident participation(gathering resident opinion, decision making, composition of construction committee, community newsletter).

Growth of cities and an increase in population result in the development-oriented policy, urban streams to lose their natural characteristics and functions by channelization, parking lot construction, and so forth. The streams fall into urban drains, which is the current status of urban streams. Recently, the interest in the stream environment and the ecosystem has been increased, and the efforts have been made to improve the traditional maintenance program for small streams. These efforts lead to the application of the natural recovery systems. This study applied the 240-meter model reach along the Oncheon stream, which locates in Dongrae-gu, Busan city. to analyze the natural recovery system. The efficiency of each system has been analyzed and the future improvements for the systems are presented. The results show that the stream maintenance program should consider the ecological environment. thereby minimizing the environmental effects. When the changes are inevitable, the maintenance program should adopt the methods. which closely simulate the original environmental elements. or are more favorable to the ecosystem.

WAS(WAffle shape Slab system) 공법은 기존의 더블티(Double Tee Slab 이하 DTS)공법의 일부 문제점을 개선하는 것을 목적으로 개발된 와플(waffle) 형상의 프리캐스트 콘크리트 슬래브 공법이다. 그러므로 기존의 프리캐스트 공법의 장점인 건설현장의 공업화, 단순화, 시스템화, 고품질화가 가능하다. 또한 더블티 공법의 경우 발생되기 용이한 부재 또는 접합부 부분의 균열 발생을 줄여 이로 인한 유지 보수 관리 비용의 발생을 저감시킬 수 있다. 이미 선행연구를 통하여 WAS패널의 구조적인 특성과 안정성, 시공성에 대해 검증하였고 후속연구로 슬래브-슬래브 간의 접합부 구조적 특징을 파악하기 위하여 본 실험을 진행하였다. 실험결과 변수로 설정한 접합부분 너비와 충전재료는 접합성능에 큰 영향을 미치지 않으므로 조립 시 덧침콘크리트가 충분히 밀실하게 채워질 수 있는 접합너비로 설계하여 사용하면 될 것으로 판단된다.

대도시에서의 공사는 외부방향이 아닌 상부로 진행되기 때문에 현장의 벽면 움직임은 매우 중요하다. 고층 구조물은 주차장을 위한 여분의 공간 확보뿐 아니라 건물의 잠재적 침하를 줄이기 위하여 일반적으로 깊은 굴착을 수반한다. 이러한 대형 굴착은 깊은 심도에 따른 횡방향 지중압력에 견디기 위한 견고한 브레이싱 시스템을 필요로 한다. 벽체 움직임은 잠재적인 인접 구조물의 침하를 허용하기 때문에 sheetpile 이나 diaphragm wall과 같은 옹벽구조물의 변형을 예측하는 방법은 매우 중요하다. 사례들을 분석하고 측정된 벽체 변형은 경험적 도표로부터 예측된 값들과 비교되었다.

PURPOSES : In this study, the effects of when median exclusive bus lanes were applied to Daejeon trunk road (Wolpyeng crossway~Seodaejeon crossway, 6.3km) and (Daeduck Bridge 4~Kyeryong 4, 2.6km) by Microscopic Simulation VISSIM (5.0) was studied. The median exclusive bus lanes are one of the measures of transportation system manage techniques that can especially improve the efficiency of public transportation facilities. METHODS : According to the analysis of VISSIM on the Gyerong mainroad and Daedeok mainroad, when the median exclusive bus lanes were applied unlike when the roadside bus-only lanes were applied, the average travel speed of vehicles decreased but the average delay time and travel time increased. This arised from the changes in the geometric structure of the road which occurred the reduction of vehicle lane in the center of the road. RESULTS : In the case of bus, on the other hand, the average travel speed increased but the average delay time and travel time decreased. This is because the problems such as illegal parking and stopping, secondary road in out vehicle, and conflict of intersection right turn that roadside bus-only lanes occurred was solved. CONCLUSIONS : Although the introduction of median exclusive bus lanes will have a negative effect on general traffic flow due to the aggravation of travel, decrease of passenger car usage will lead to decrease of traffic volume. Therefore, smooth vehicle travel is expected.

Unlike the projects that the government has implemented recently to develop new cities under the New Deal project, Saeddeul Village projects to improve the environment of the city are gaining attention. The problem has been found to be that many of the buildings in Saeddeul Village are still not earthquake-proof by using drones to review the state of the town. It also revealed that after two years of earthquakes, Pilotis structures are the most vulnerable to earthquakes. However, it is suitable for small spaces in the city because it provides parking spaces as well as residential spaces. Accordingly, the focus should be on repair and reinforcement rather than reconstruction. In this study, a concrete-based seismic design and construction method is developed in the columns of the existing pylotis structure.

This paper proposes a method for detecting the front side of vehicles. The method can find the car side with a license plate even with complicated and cluttered backgrounds. A convolutional neural network (CNN) is used to solve the detection problem as a unified framework combining feature detection, classification, searching, and localization estimation and improve the reliability of the system with simplicity of usage. The proposed CNN structure avoids sliding window search to find the locations of vehicles and reduces the computing time to achieve real-time processing. Multiple responses of the network for vehicle position are further processed by a weighted clustering and probabilistic threshold decision method. Experiments using real images in parking lots show the reliability of the method.

To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.

Eco-village is an alternative community which applies ecological principles to the development of human ecosystem in order to achieve sustainability. Ansolgi village in Korea has been established five years ago, in 1999, by a group of environment conscious families. The author has visited and stayed in the village twice during last two years, for several days each time, and observed and surveyed the changes of physical, social, and cultural aspects of the community. They adopt more environment friendly techniques in building their houses, sewage system, roads and parking, and growing their own foods, and so on. The residents have diverse jobs, many of them outside the village as the village lacks job opportunities. The residents themselves often question the sustainability of the village and reluctant to identity Ansolgi as an eco-village. Most residents joined the community with their own images of an eco-village and find it difficult to reach consensus on what the eco-village should be like and how it should be managed and maintained. Residents wish to get government assistances and professional guidance. This paper concludes it is still very difficulty and problematic to establish an eco-village in Korea.
