본 논문에서 유교문화콘텐츠를 기반으로 도시 브랜드화 전략을 통해 도시가 활성화된 사례를 분석하고 도시 브랜드의 가치 향상과 도시의 활성화 요인을 고찰하고자 한다. 유수의 도시들이 문화자원을 통해 경쟁력을 확보하고 있으며 특히 전통문화는 차별성을 확보해주는 중요한 자산으로 그 가치가 더욱 부각되고 있다. 우리나라 문화 전반에 흐르고 있는 유교는 건축학적인 문화유산 뿐 만 아니라 예법, 문묘제례, 교육, 음식 등의 다양한 콘텐츠를 담고 있어 활용가치가 높은 문화자원이다. 그러나 대다수의 유교문화자원은 보존 및 운영에 어려움을 겪고 있으며, 무형의 자산 또한 활성화되지 못하고 방치되고 있는 실정에 있어 이를 지역의 특색에 맞게 특성화하여 도시의 브랜드화 전략에 적극적인 활용이 필요하다. 이를 위해 대표적인 유교문화도시인 안동시와 중국 산동 곡부시의 사례를 살펴봄으로서 유교문화콘텐츠를 활용한 도시브랜드 활성화 방안을 도출하고자 한다.

In this study, Allied Signal 211 SOG was used as a sacrificial material. After researching its etching properties, we adapted it to bottom-drive micrometers. SOG was superior etch rate and roughness to them of PSG or CVD-oxide and possible to low-temperature processing. Etching properties of SOG depended on the temperature and duration of its bake and cure. SOG used in the fabrication of bottom-drive micrometers showed us usefulness as a sacrificial layer and haying a least influence on machines on it in comparison with conventional sacrificial materials.

A simulation study was conducted to use city-water which is thermally regulated by unused energy as a heat source for urban dwellings. This study utilized multiple heat pump system using the city-water as a heat source and suggested a method of reducing the heat load of hot water supply. The simulation was done to calculate the energy savings at a dwelling for a year. The relation between the controlled temperature of city-water. and electric energy in all seasons was also investigated. Furthermore, it has been found that the controlled water system can lead to considerable energy savings and decrease environmental load such as sensible waste heat which otherwise would form heat islands.

In order to investigate the seroprevalence of Salmonella Pullorum in boilers reared in Daejeon area, 509 samples were collected from 10 boiler farms randomly selected from 38. The survey was carried out during 6 months from April to October in 2007. Out of 509 chickens, 35 (6.9%) were seropositive and average titer was $2^{4.8}$. The seroprevalence by district was 5.5% (5/90) in Dong-gu, 4.1 % (4/96) in Seo-gu, 7.9% (24/303) in Yuseong-gu, 10.0% (2/20) in Daedeok-gu.

This paper describes a novel multi-operand radix-2 signed-digit(SD) adder. The novel multi-operand addition algorithm can eliminate carry propagation chain by dividing the input operands into even place part and odd place part, and adding them each. The multi-operand adder with this algorithm can add six operands in parallel, and is faster than the ordinary method of SD adder binary tree. A hardware model for proposed adder is shown which is implemented by the current-mode MOSFET circuit technology. Simulations have been made by SPICE in order to verify the function of the proposed circuit.

Objectives: This study evaluated the effect of construction on ambient PM-10 in the surrounding area. Methods: Four study sites were selected from total AAQMN 11 points in Daegu city. All the four study sites were located near under or completed construction. Mean monthly PM-10 in 2007 to 2013 were analyzed. Results: Impact of residential construction on PM-10 was more obvious than industrial area. PM-10 was positively associated with number of construction near the study site. When there were 2 or 3 construction sites, PM-10 level was higher. Wind direction and the surrounding terrain affected PM-10. Conclusions: Construction has a strong influence on PM-10 in the surrounding Area. Reduce PM-10 there is the need for special construction site management. Proper management is required to minimize fugitive dust in construction sites.

The Ministry of Land, Infrastructure and Transport (MoLIT) and the Korean Automobile Testing and Research Institute (KATRI) are supporting the development of Lv.3 automated vehicle (hereinafter, AV) technology by constructing an automated driving pilot city (as known as K-City) equipped with total 5 evaluation environments (urban, motorway, suburban, community road, and autonomous parking facility) which is a test bed exclusively for AV (2017~2018). An upgrade project is in a progress to materialize harsh environments such as bad weather (rain, fog, etc.) and reproduction of communication jamming (GPS blocking, etc.) with the purpose of supporting the development of Lv.4 connected & automated vehicle (hereinafter, CAV) technology (2019~2022). We intend to proactively establish a national level standard for CAV test-bed and test road requirements, test method, etc. for establishment of a road map for the construction of the test bed which is being promoted step by step and analyze and, when required, benchmark the case of China that has announced and is utilizing it. Through this, we plan to define standardized requirements (evaluation facility, evaluation system, etc.) on the test bed for the development of Lv.4/4+ CAV technology and utilize the same for the design and construction of a test bed, establishment of a road map for the construction of a real car-based test environment related to the support for autonomous driving service substantiation, etc. through provision of an evaluation environment utilizing K-City, and the establishment of a K-City upgrade strategies, etc.

최근 지역 환경의 문화적 중요성이 증대함에 따라 지역 주민의 도시디자인에 대한 관심이 늘어나고 있다. 이러한 도시디자인을 통하여 지역 주민들의 자긍심을 고취시키고 대내외적으로 그 지역의 도시이미지를 재정립할 수 있다. 이에, 본 연구에서는 특정 도시(포항시)의 현황 및 환경적 특성 그리고 시민의 디자인 이미지 선호도를 분석하고, 이를 바탕으로 도시이미지 정체성을 구현할 수 있는 대상으로서 '가로'를 구성하는 공공시설물의 표준디자인 제안을 기본적인 목적으로 하였다. 이를 위하여 해당 도시의 24개 지역에 대한 경관이미지 및 공공시설물 설치 현황을 분석하였다. 또한 해당 도시의 일관된 이념과 사상, 이미지를 구축할 수 있는 공공시설물의 디자인 방향을 도출하기 위하여 시민들의 공공시설물에 대한 감성적 디자인 선호이미지를 조사, 분석하였다. 이러한 분석 내용을 바탕으로 총 31종의 공공시설물에 대한 디자인 가이드라인을 설정하였으며 표준디자인을 제안하였다. 이러한 결과를 통하여 매력 있는 도시이미지를 표출할 수 있는 커뮤니케이션 매체의 제공이 가능하고, 향후 포괄적인 도시 경관계획에 반영할 수 있는 자료의 제공이 가능할 것으로 기대한다.

Objectives: The purpose of this study was to compare Fast foods and Soft drinks consumption of Korean adolescents in a large city, a medium city, and a rural area. Methods: This was a descriptive comparative survey using a convenience sample of 2,261 8th and 11th grade students. The data were analyzed by X2-test and ANOVA using SPSS 10.0 statistical program. Results: For fast food consumptions, the higher in a large city than in a medium city and a rural area(p=.000). For soft drinks in a school, cafeteria or vending machines was higher in a large city and a medium city then in a rural area(p=.000). For eating snacks including cookies and popcorns was higher among students in a rural area than those in a medium city and large city(p=.008). Conclusions: 1. Overall, the health information among rural students is lower than those among other areas, as well as taking a health education course among rural students is also lower. Thus, the health inequality by regional differences should be considered. To decrease health inequality among different regions, health professionals who can systematically teach a health education course for middle and high school students and undertake students' health are needed. 2. Soft drinks sold in schools are higher in a large city and medium city than in a rural area. Therefore, there is a need of strong regulations and policies about the restriction of soft drinks sold in vending machines or school cafeterias.

This paper presents the understandings carried out for the installation of the hydrogen reservoir of the multi-gap pseudospark switch under developing for the accelerator applications. As a cold cold cathode switch, the pseudospark switch could replace the thyratron switch which has hot cathode and being used well currently in the high power field such as laser and accelerator applications. Especially in the klystron modulator, the key component is a switch which mostly defines the jitter and the instability of the modulator system. To get the less jitter and the instability, we need to find proper range of the pressure for the gas discharge inside gas switch. This could be achieved by the understanding of the characteristic of the nonevaporable getter (NEG) which is used as a hydrogen reservoir for the switch. Therefore we verified the characteristics of the NEG (St 172, Saes) and its installation in the switch. Finally we controlled the getter to find best pressure point for the pseudospark switch.
