본 연구에서는 현재 일반적인 스마트 팩토리에서 데이터 전송에 사용하는 중앙 집중형 시스템에서 발생하는 데이터를 중앙의 센터까지 전송, 처리할 때 발셍하는 전송 지연 등의 문제 해결을 위하여 필요한 곳에 연산과 저장 장치를 도입하는 분산 컴퓨팅 패러다임 (Distributed Computing Paradigm)인 온-디바이스 (On-Device) 기반 에지 컴퓨팅 (Edge Computing) 기술과 빅데이터 분석 기술 및 활용 방법의 연구를 통하여 설비 고장 등을 예지하여 가동율을 높일 수 있는 산업현장의 설비관리에 활용되는 솔루션을 제안한다. 그러나 에지 컴퓨팅 기반의 기술이 실제 적용되더라도 네트워크 에지에서 장치의 증가는 많은 양의 데이터가 데이터 센터로 전달되어 네트워크 대역이 한계치에 이르게 되어 네트워크 기술의 향상에도 데이터 센터는 수많은 응용에서 중요한 요건이 되는 수용 가능한 전송 속도와 응답 시간을 보장하지 못하게 된다. 이와 같은 요구조건을 수용할 수 있는 일체형 하드웨어 기술과 공장관리 및 제어 기술을 적용한 설비보존 및 스마트 팩토리 산업 분야에 적용할 수 있는 연구를 통하여 생산성 증대를 지원할 수 있는 지능적 설비관리를 지원하도록 하여 추후 빅데이터에 적합한 딥러닝을 적용할 수 있는 인공지능 기반 설비 예지 보전 분석 도구로 발전할 수 있는 기반을 제공한다.

사용후핵연료 최종처분장 건설 과정에서 발생하는 굴착손상영역(EDZ)은 처분시설의 역학적 안정성 및 처분공 간격 설정 등의 설계요소로서 고려해야 할 뿐만 아니라 영역 내 투수특성은 폐쇄 후 지하수 유입량 변화에 따른 처분용기 부식 속도 및 핵종유출 등에도 막대한 영향을 미치게 된다. 따라서, 처분시설 및 관련 지하연구시설(URL)의 건설과정에서는 EDZ의 발생양상을 현장에서 정확하게 파악하고 미리 규정된 요건을 만족할 수 있도록 철저하게 관리할 수 있어야 한다. 이 논문에서는 핀란드 온칼로 시설에서의 EDZ 관련 연구사례를 검토하고 처분시설 굴착과정에서의 EDZ의 현장평가방법 및 시공품질관리 체계에 대해 검토하였다. EDZ 현장 평가를 위해서는 굴찰 갱도 주변의 교란을 유발하는 시추공 굴착이 불필요한 GPR 탐사가 가장 적합함과 온칼로 처분시설의 EDZ는 바닥부에서 두드러지게 발생하여 0~70 cm의 두께로 발생함을 확인하였다. 이들 결과는 국내 처분환경에 적합한 EDZ 관련 규제요건 개발에 유용한 정보를 제공할 수 있을 것으로 기대된다.

경주의 월성에 대한 발굴 작업 없이도 고고학적인 호기심을 충족시킬 수 있도록 비파괴 조사방법의 일환인 GPR(Ground Penetrating Radar) 탐사법을 적용하여 지하유구의 존재 상황을 조사하였다. 이는 현대고고학과 지구물리학을 접목하여 향후 발굴계획이나 고고학적 연구에 과학적이고 체계적인 접근 전기를 마련하고자 하는 의미도 있다. GPR 탐사는 석빙고 앞 및 성의 동편 끝 지역에서 실시되었으며 향후 3차원 자료처리 및 해석을 위해 조사대상지 전체에 대해 조밀한 측선을 설정하였다. 구성된 3차원 볼륨 자료를 고고학적으로 해석한 결과, 대형 건물지 7채와 담장 및 성의 출입시설, 수많은 초석들, 도로,그리고 원지 등을 추정할 수 있었다.

With the change of family type and diversify of life style, residents need various unit plan in Quality. A rate of economically productive women has increased, and generally double-income households will continuously increase in the future. So a research is requested to consider the double-income households's satisfaction for a unit plan based on their life characteristics. The purpose of this study is to find out double-income households's lifestyles, and to search and analyze users' needs for spatial composition according to their lifestyles, and then, embody spatial composition of Apartment Unit plans. The findings are as follows. (1) Housing lifestyles of users living in apartment are categorized into 5 types: seeking the way to make housework easy and comfortable, making the best use spatial composition, pursing the universalism, housework oriented, pursing the leisure. (2) The type of seeking the way to make housework easy and comfortable requests facility with home appliances and a shower bath, the type of making the best use spatial composition requests storage space and trial about new plan, the type of pursing the universalism is concerned about the protection of environment and a memorial service, the type of housework oriented wants a talk with their family and discuss some problem, and the type of pursing the leisure requests division of household with their family and likes traveling and sports.

The objective of this study is to make a comparative study of the operation performance of different type of solar collectors. A flat-plate collector, a single-glazed evacuated collector and a double-glazed evacuated collector are used in this study. These 3 type of collectors are connected in series in the order of a flat-plate collector, a single-glazed evacuated collector and a double-glazed evacuated collector. This experimental facility is a kind of a solar system with a controller, a heat exchanger, a storage tank and a circulation pump. Each collector has a different collection area(flat-plate collector-$6.00m^2$ total area/$5.61m^2$ aperture area, double-glazed evacuated collector-$6.04m^2$ total area/$4.92m^2$ aperture area, single-glazed evacuated collector-$7.65m^2$ total area/$5.61m^2$ aperture area) and its performance characteristic respectively. The experiments have been demonstrated at around $70^{\circ}C$ operating temperature(flat-plate collector inlet temperature). The thermal collecting efficiencies of each collector are obtained under the different insolation and operation condition as a result.

To do this the survey was carried out for the frequency, criticality and difficulty of each job description with 4 point scales. The subjects was 521 dietitians, who have been working over 3 years at their position. The results are following ; 1. The each duty, task and task elements are verified with survey results. 2. Duties with high frequency and criticality were menu management, purchasing, storage and stock management, operational management for cooking, system management for distribution and sanitation management. 3. Duties with middle frequency and high criticality were managing equipment and facility, food service management, human resources management and self-development. 4. Duties with low frequency and high criticality were nutritional assessment for life cycles, nutrition therapy, nutrition education and disease management. 5. For difficulty, food service area show lower than of nutrition service area.

This research was to analyze the inland signal-fire which is the main facility of military protective duty for safety of land in chosun dynasty. The results of this research were described separately as follows. 1. Five types of site plan of signal-fire were observed, which is circle, oval, rectangular, indeterminate form. The majorities were oval type. 2. Plan configuration of brazier which is separated with circle, rectangular type roughly was constructed with circle type generally. The height of brazier was about 3~4.5m. The diameter of brazier was 1.5~2.5m. Building base that protect ground moisture and infilteration of rainfall was found in 5 inland singal-fire, the height of it was about 0.3m~2.5m. 3. The heigh to protective wall remained until present was about 1m, the depth was about average 1.2m. 4. Entrance was mainly stairs or open type and average width was 1.0~1.2m. However the depth was almost observed as 1m, originally, it was estimated it has more depth. 5. The storage of inland signal-fire has rectangular dimension, several types of $1.8{\times}1.2m{\sim}5.7{\times}4.4m$, square(間) of $1{\times}1{\sim}2{\times}1$. The building material was stone and located below or near the brazier.

This study examined the general housing awareness and awareness on house sharing of college students who are present residents as well as potential residents of shared houses. To achieve this purpose, structured questionnaires were used as a survey tool to understand students' awareness on housing and opinions on house sharing including a range of space sharing, preferences on house mates, and demands on services and facilities. The survey was conducted of college students in Busan, and the data were analyzed by the PASW Statistics 18.0 program. The findings of this study are as follows: 1) The housing awareness was categorized into seven factors by factor analysis. The subjects valued 'personality factor' in the housing awareness. 2) Regarding preference of house mate type, participants preferred a person who has similar lifestyle and in the same gender. 3) As for the space sharing, the subjects didn't want to share a bathroom and shower. Also, they preferred medium or large scale dormitory layout type to small sized apartment type. 4) The most positive aspect of house sharing was 'Reduction of rental and maintenance cost'. On the other hand, 'Difference of daily life pattern' was the most negative aspect of house sharing. 5) In case of services and community spaces, they preferred 'delivery storage service' and 'coin-operated laundry facility'.

For the efficient operation and maintenance( 0 & M), irrigation facilities were graded on the basis of their indices related to the 0 & M condition and the characteristics of reservoirs managed by Farmland Improvement Association(FIA) were examined. The results obtained are summarized as follows : 1. Characteristics of reservoirs include effective storage capacity, irrigation area, basin area, height and length of bank. Each characteristic is scored by the principle component analysis method. Variables which compose one index are categorized on the basis of their unit and each variable is scored so that the score of each unit sums to 100 for each index. 2. The Optimum MAnagement System of Irrigation Facilities(OMASIF) for Pyoungtaek area was developed by connecting general data of the irrigation facilities to image data. The database system is divided into three tables; LookUp Table, Facility Table, and Image Table. Image Table is again divided into five sub-tables, Image Table, Construction Cost Table, Acreage Table, 0 & M Cost Table, and Specification Table. 3. The evaluating criteria for the 0 & M of irrigation facilities can be established using the OMASIF. Irrigation facilities evaluated as poor state by the criteria should be repaired.
