우동명,선상,강태호 한국전통조경학회 2015 한국전통조경학회지 Vol.13 No.-

Bridges are built over rivers, gorges or other places where roads are impossible. Those which have traffic, decorative and cultural functions are usually named as garden-bridges. Mount Tai Scenic Area locates in the middle part of Shandong Province, China. It is renowned for its rich natural and cultural resources and ranks No.1 among the five most important mountains in China. It was honored as Mixed World Heritage and Global Geopark. There are decades of different bridges in the Scenic Area. Most of them have important values. Based on field survey and literature research, this paper takes the two main route (mid-climbing rout and west climbing route) as the research objects. The landscape characteristics of garden-bridge together with the surrounding environmental elements are studied. The environmental elements are classified into two categories according to their attributes and existing forms: one is natural and the other is cultural. Furthermore, The natural category includes topography, water, plant and climate etc. The cultural elements mainly consist of memorial archway(牌坊), pavilion and stone inscription etc. Their functions and effects on the garden-bridges are analyzed systematically. As a result, integrating the garden-bridge with the surrounding environmental elements as an organic group, garden-bridge landscape making techniques such as scenery inscription, view borrowing, opposite scenery, frame scenery and obstructive scenery are discussed. It puts forward to give some theoretical and practical references to the garden-bridge’s planning and design, protection and improvement in mountainous scenic areas.

우동명,장푸천,강태호 대한관광경영학회 2016 觀光硏究 Vol.31 No.4

Ancient villages are attractive places to the artists and tourists for their unique natural and cultural heritage. This research investigates the ancient villages locate in E’zhuang Town, a mountainous area in middle-Shandong Province, which are the national-renowned destination for artistic sketch and rural tourism. The research adopts methods of field survey, questionnaire and interview. 18 economic, social, ecological and cultural indexes are selected for the investigation of local residents’ perceptions and attitudes towards the development of sketch base and rural tourism industry. Based on the research, the paper explores the differences in perceptions and attitudes among local residents with different demographic features such as gender, age, education level and family income etc. The results show that the common attitude is positive which means local residents are willing to contact and be in harmony with the painters and tourists. The research will do some help to promote the formulation of policies for the related decision-makers to avoid or shorten the apathy, annoyance or even antagonism Stage.

우동명(Dong-myung Woo),김동선(Dong-seon Kim),류장렬(Jang-Ryeol Ryu) 한국정보기술학회 2019 Proceedings of KIIT Conference Vol.2019 No.6

본 연구는 초음파 센서(Ultrasonic Sensor)와 라즈베리파이(Raspberry Pi)를 사용하여 근무 중인 회사 내 노후화된 시험설비의 정확도 향상을 위한 시스템을 개발하고자 하는 목표이다. 이를 위해 라즈베리파이3, 초음파센서, 온습도 센서 등을 연결하여 시스템을 구성하였다. 또한 초음파 센서와 온습도 센서의 측정확도 향상을 위하여 자체 교정을 진행 후 보간법을 사용하였고, 온도의 변화에 따른 초음파 센서 거리 측정 오차를 줄이기 위하여 온도를 측정하여 온도에 따른 초음파 센서 거리 계산 함수를 추가하였다. 추가로 모니터링 시스템은 html로 코드를 작성하여 시험자는 운영체제 및 웹브라우저에 상관없이 모니터링이 가능하여 회사 시험실 내 어디서든 실시간으로 시험설비의 상태를 알 수 있다. 본 연구를 통해 시험자는 스로틀 위치를 정량적으로 확인할 수 있었으며, 후단팬의 사용 불가 영역을 회피하여 시험 설비의 정확도 및 안정도 향상을 도모하였다. The purpose of this study is to develop a system for improving the accuracy of the aging test equipment in the company using ultrasonic Sensors and raspberry Pi. For this purpose, the system was constructed by connecting Raspberry Pi 3, ultrasonic sensors, and temperature and humidity sensor. In order to improve the accuracy of the ultrasonic sensors and the temperature and humidity sensor, the interpolation method is used after the self calibration. In order to reduce the measurement error of the ultrasonic sensors according to the temperature change, the temperature is measured and the ultrasonic sensor distance calculation function according to temperature is added. In addition, the monitoring system writes code in html, allowing the tester to monitor the operating system and web browser regardless of the status of the test facility from anywhere in the company laboratory. Through this study, the tester was able to confirm the throttle position quantitatively and avoid the unusable area of the rear fan, thereby improving the accuracy and stability of the test equipment.

중국 산동성 중부 산간에 위치하고 있는 아장고촌은 전통 농촌마을로서 오랫동안 축적되어 온 자연과 인문환경의 특색을 잘 간직하고 있어 관광객과 예술가들이 자주 찾아가는 곳이다. 본 연구는 농촌을 대상으로 하는 사생화 활동이 관광 발전에 미치는 영향을 분석하고자 수행하였다. 연구 방법은 경제, 사회, 생태, 문화 등 마을의 관광 발전에 영향을 미치는 18 가지 지표를 선정하고 현장조사와 설문조사를 통해 사생화 활동이 마을 관광 발전에 미치는 영향에 대한 마을주민들의 인지와 태도를 분석하였다. 연구 결과 마을주민의 성별, 연령, 문화 수준, 가계소득 등 인구학적 특징의 차이에 따라 사생화 활동과 관광 발전에 대한 인지와 태도가 다르게 나타났지만 전체적으로는 긍정적으로 나타나 마을주민이 예술인 및 관광객과 조화롭게 지낼 수 있을 것으로 판단된다. 아울러 부정적인 측면으로 나타난 마을주민의 ``냉담``, ``걱정, ``반대`` 등 소극적인 태도를 효과적으로 감소시키기 위한 정책 방향 제시에 유용한 자료가 된다.

김경남,우동명,박현,Kim, Kyung-Nam,Woo, Dong-Myung,Park, Hyun 한국결정성장학회 2011 韓國結晶成長學會誌 Vol.21 No.6

본 연구는 석탄회(Fly Ash)와 점토를 이용하여 광미(tailing)의 중금속 안정화를 연구하였다. 플라이애쉬-점토-광미계의 특성은 여러 분석기기(SEM, XRD, XRF, TG-DTA, Dilatometer, UTM)를 이용하여 광미의 첨가량에 따른 물리 화학적 특성을 조사하였다. 플라이애쉬의 화학조성은 $SiO_2$가 33.01 wt%, $Al_2O_3$는 28.54 wt%, CaO가 9.97 wt%이고 이외에 $Fe_2O_3$와 알카리 성분 등을 함유하고 있으며, 강열감량은 플라이애쉬가 20.26 wt%로 나타났다. 플라이애쉬의 $SiO_2$와 $Al_2O_3$ 조성양은 점토성분이 61 wt% 이상이다. 그리고 광미의 화학조성은 $SiO_2$가 26.91 wt%, CaO가 24.25 wt%, $Fe_2O_3$는 22.97 wt%이다. 그러므로 플라이애쉬-점토-광미계에서 플라이애쉬가 점토의 원료로 대체가 가능하다. 시편의 수축은 $850^{\circ}C$ 부근에서 서서히 수축이 시작되어 $1100^{\circ}C$ 부근에서 급격하게 수축하는 것을 볼 수 있었으며 플라이애쉬의 탄화 분해 과정에 의해 영향을 받는다. 시편의 미세구조는 광미를 첨가한 시편이 치밀하였다. 열처리 온도에 따른 물리적 특성 조사를 위하여 흡수율과 압축강도를 측정하였으며 광미를 첨가한 시편의 압축강도가 높으며 약 200~420 kgf/$cm^2$로 KS L 4201의 점토 블록 기준 내에 있다. 그리고 광미의 중금속의 안정화는 소결한 후에 한국폐기물 규격내에서 안정화한 것을 알 수 있다. This research was performed to stabilize heavy metals in mine tailing using fly ash and clay. Fly ash-clay-mine tailing system were investigated using XRD (X-ray diffractometer), XRF (X-ray fluorescence spectrometer), TG-DTA, SEM (Scanning Electron Microscope), Dilatometer and UTM with various mine tailing contents (~15 wt%). The fly ash used in this research was mainly composed of $SiO_2$ (33.01 wt%), $Al_2O_3$ (28.54 wt%), $K_2O$ (3.32 wt%), $Fe_2O_3$ (1.47 wt%), CaO(9.97 wt%). $SiO_2$ and $Al_2O_3$ composition of the clay was over 61 wt%. And the mine tailing have high composition of $SiO_2$ (26.91 wt%), CaO (24.25 wt%), $Fe_2O_3$ (22.97 wt%). Therefore, it was estimated that fly ash-clay-mine tailing have enough sintering characteristics. The shrinkage of specimens started at around $850^{\circ}C$ and changed little up to $1100^{\circ}C$, but increased markedly at above $1100^{\circ}C$. The shrinkage rate is strongly related to the decarbonization amount of coal fly ash. As the result of SEM, structure of the specimens with mine tailing addition showed more close than the one without mine tailing. Compressive strength of the specimens with mine tailing was highly increased to approximately 200~420 kgf/$cm^2$, it satisfied the first grade criterion for clay brick by KS L 4201. The specification of leaching characteristics of the sintered specimens were within the Korean regulation standard.
