본 논문에서는 교통 모니터링 시스템에 사용할 수 있는 국부 영역에서 차량 검지와 추적을 수행하는 새로운 기법을 제안하다. 차량 검지와 추적은 각 차선에 미리 설정된 영역에서만 이루어진다. 각 차선에 설정된 국부 영역을 에지 특성과 프레임 차이를 이용하여 여러 개의 분할 영역으로 나누고 분할영역의 통계적 특성과 기하학적 특성에 의해 차량, 도로, 그림자와 전조등 영역으로 분류하여 차량을 검출한다. 검출된 차량은 에지 영상의 정합에 의해 국부 영역내에서 추적하여 차량 속도, 길이, 차간 거리와 도로 점유율과 같은 교통 정보를 산출할 수 있다. 배경 영상을 사용하지 않으므로 다양한 조건에서 사용이 가능하고 다양한 기상, 시간대와 장소에서 90.16%의 높은 차량 검출의 정확도를 나타냈다. 동작 환경에서 카메라의 각도, 방향과 조리개 설정이 조정되면 아주 높은 정확도의 교통 모니터링 시스템의 핵심기술로 사용될 수 있을 것으로 기대된다.

The purpose of this study is to present a plan to distinguish 229 local governments nationwide by taking into account various characteristics such as population, employment, housing, and industry of the region for customized urban policies in the era of metropolitan areas. The National Statistical Portal (KOSIS) collected and standardized data related to population, housing, industry, and finance by region from 2000 to 2015 for the classification of regional types necessary for customized urban policies, and this was used to classify them into regional types that considered population, employment, housing and industry. The summary of the analysis results is as follows. First, as a result of the regional type classification, 10 key employment sites (4.4%), 5 employment centers (2.2%), 38 residential centers (16.6%), 20 growth areas (8.7%), 26 industrial cities (11.4%), 35 low-fertile farming and fishing villages (15.3%) and 95 stagnant areas (41.5%). Second, the Seoul metropolitan area is the most diverse type of metropolitan area in the country, with most of its core employment sites inside Seoul, residential centers inside and outside Seoul, and growth areas in the southeastern part of the country (Busan, Ulsan, and Gyeongsangnam-do) are mixed with industrial and growth areas centered around Busan, Ulsan and surrounding areas, while the rest of the local governments are found to be low-fertile farming villages or stagnant areas. Daegu (Daegu, Gyeongbuk) is an industrial city in Daegu, and the rest of the local governments are either low-density farming and fishing villages or stagnant areas. The Honam region (Gwangju and Jeolla) was found to be a low-mill farming and fishing village or stagnant area except for Gwangju, while the Chungcheong region (Daejeon, Sejong, and Chungcheong) was seen as a growth area with areas adjacent to Daejeon, Sejong, and the Seoul metropolitan area, and some industrial cities were included. Finally, the Gangwon area was mostly classified as low-density farming and fishing villages and stagnant areas.

The measurements of monochromatic line-of-sight flame emission and light transmission in the same path having small spatial resolution were performed in an axisymmetric laminar propane $C_{3}H_{8}$ diffusion flame. The light wavelengthes of 632 nm, 800nm, 900nm were used. From these measurements, local point soot radiances (by Kirchhoff's law) and absorption coefficients were reconstructed by tomography. Thus local point soot temperatures and concentrations were obtained. The reconstructed soot temperatures and concentrations of local points have no differences between the case of visible range (632 nm) and the case of infrared range (800 nm and 900 nm). In these ranges, the scattering coefficient is much lower than the absorption coefficient. Soot mean temperature over the path also matches well with local soot temperature in outer region of the flame. Temperature measurement by thermocouple with different bead diameters $(222{\mu}m and 308{\mu}m)$ was carried in the same flame. Rapid insertion technique was used and radiation effect was considered. Radiation correction in the sooting region was carried out and the corrected result was in good agreement with the local soot temperature.

Based on the application of te theory of conjugate approximations and the Loubignac's iterative method in a local region, a method to improve the stress filed in a displacement-formulated finite element solution has been proposed. The validity of the proposed method has been tested through two examples : a thick cylinder under internal pressure loading and an infinite plate with a central circular hole subjected to uniaxial tension. As a result of analysis of the examples, it was found that the stress field obtained for the local region model by the proposed method approximates well for the whole domain model. In addition, it was found that because of a significant decrease in the computing time to obtain the improved stress field, the proposed method is efficient and useful for the detailed stress analysis in local regions.

Busan is an underdeveloped region in food culture, though it has geographically convenient conditions of location to make good use of marine products from the sea and the river, a variety of grain and vegetables, and forest products. Thus, in this research, I studied the traditional and local native foods of Busan, focusing on there origins and the backgrounds of their development. There are many traditional and local native foods in Busan, Pajun, Macguli, Jaechupguk, Gupoguksoo and etc. For the development of food culture of Busan, We will keep researching its traditional and local native foods and try to form a new pattern of food culture, making the adventage of an international trading city.

국내 각 지방자치단체의 커뮤니티아이덴티티 (community identity) 프로그램은 지역 활성화를 중요한 목적으로 한다. 커뮤니티아이덴티티는 타 지자체들과 차별화 된 이미지를 확립하고 동시에 지역주민의 애향심과 소속감을 높일 수 있는 매우 효과적인 방법 중 하나이다. 커뮤니티아이덴티티 외에도 지방자치단체의 아이덴티티를 형성하는 요소로서 꽃, 새, 동물 등의 각 지자체 상징물이나 그 지역과 연고가 있는 인물, 전통, 특산물 등을 시각화한 캐릭터가 있다. 최근에는 시티브랜드와 같은 마케팅지향의 브랜드 계획, 지역이벤트 등 다양한 프로그램들을 도입하고 있다. 본 연구는 현재 도입된 국내 지방자치단체 커뮤니티아이덴티티의 시각요소 중 심벌마크, 로고타입, 색상 등의 가장 기본적인 요소와 각 지자체의 상징물, 캐릭터의 시각요소 현황을 조사 분석하였다. 그 결과 각 지방자치단체의 커뮤니티아이덴티티 및 기타 디자인요소들의 차별성이 부족하고 여러 시각 요소들 간의 일관성도 결여된 것으로 나타났다. 지방자치단체의 차별화 된 이미지 형성을 위해서는 지역이 갖고 있는 보다 특색 있고 다양한 소재 개발과 커뮤니티아이덴티티를 중심으로 여러 시각요소들의 일관성과 상호작용을 통한 시너지효과를 유도해야 할 것이다.

Background and objective: There are many theories related to the development of agrotourism, and each stakeholder has its own role and function. If it is based on organizational functions, stakeholders need to be coordinated, and the state plays a major administrative role. But in the successful case of Yeongdong County, Chungcheongbuk province, the Republic of Korea, the government played an important role in the development of tourism, which grants us another perspective on the role of the government in promotion and development agrotourism activities. Methods: This article aims to examine the development of agrotourism through a cooperative approach, by clarifying the role of the local authorities in the Yeongdong region in the management and operation of the local agrotourism activities. The qualitative research method is based on a field survey conducted in Yeongdong County in 2019. Results: The study's findings show that in situations where conflicts of interest among stakeholders are prone to occur, the development of local tourism has a limited impact on the cooperative culture, and local governments play an important role. Accordingly, the local governments must actively formulate strategies to maintain and develop traditional agricultural industries and at the same time develop agrotourism activities. The government's ability to coordinate, cooperate, and participate reasonably is a key factor for the success of the sustainable development of the tourism industry. Conclusion: Based on coordination between stakeholders and a reasonable strategic direction, Yeongdong's agrotourism is being effectively deployed. The development of Yeongdong's agrotourism industry has achieved impressive results through an effective strategy, highlighting the important role of localgovernment in the consensus of local communities and collaboration with stakeholders. The role of outstanding local governments has been clearly demonstrated, especially in promoting, establishing, and contacting different organizations to effectively deploy agrotourism in the region.

This paper presents a sole application of boundary element method to the conjugate heat transfer problem of thermally developing laminar flow in a thick walled pipe when the fluid velocities are fully developed. Due to the coupled mechanism of heat conduction in the solid region and heat convection in the fluid region, two separate solutions in the solid and fluid regions are sought to match the solid-fluid interface continuity condition. In this method, the dual reciprocity boundary element method (DRBEM) with the axial direction marching scheme is used to solve the heat convection problem and the conventional boundary element method (BEM) of axisymmetric model is applied to solve the heat conduction problem. An iterative and numerically stable BEM solution algorithm is presented, which uses the coupled interface conditions explicitly instead of uncoupled conditions. Both the local convective heat transfer coefficient at solid-fluid interface and the local mean fluid temperature are initially guessed and updated as the unknown interface thermal conditions in the iterative solution procedure. Two examples imposing uniform temperature and heat flux boundary conditions are tested in thermally developing region and compared with analytic solutions where available. The benchmark test results are shown to be in good agreement with the analytic solutions for both examples with different boundary conditions.
