In this study, we analyzed all of the waste streams associated with household waste to provide a basis for incorporating the individual characteristics of municipalities in setting targets for waste-to-resource circulation. Toward this end, we examined how household waste is treated based on the disposal method (mixed waste disposed of in standard volumerate garbage bags, separation recyclable waste, and food waste) and the amount of residuals generated at their respective treatment facilities. The actual recycling rate or actual waste-to-energy conversion rate was calculated as the ratio of the actual amount of waste that is recycled or converted to energy against the amount of waste intake at waste treatment facilities. The conversion factor of actual recycling rates at 17 municipalities showed an average of 63.9% for public material recovery facilities (MRFs) with those for individual municipalities ranging from 50.4% to 93.2%, and an average of 93.8% for private and public food waste treatment facilities with slightly higher rates found for public facilities (70.4 ~ 100%) than private facilities (63.3 ~ 100%). The actual waste-to-energy conversion factor was 59.3% on average for combustible waste-to-energy facilities (17.2 ~ 72.3%) and 92.0% on average for biological waste-to-energy facilities (77.1 ~ 99.5%). To achieve the national target for the actual recycling rate, additional strategies for recycling or converting the residuals generated at recycling or combustible waste-to-energy facilities into resources are needed. The actual recycling and waste-to-energy conversion rates provided in this study based on a full examination of household waste streams hold valuable insights for incorporating the individual situations of municipalities in setting their targets for wasteto- resource circulation indicators and creating new strategies for improving the actual recycling rate.

본고에서는 일본에서 말하는 영유권 주장의 근거로서 죽도(독도) 활용실태에 대해 그것이 어떠한 것이었는가를 검토하고자 했다. 일본정부가 죽도(독도)의 활용실태를 주장함에, 오키섬에서 죽도(독도)로 직접 가서 어로로서 죽도(독도)를 활용한 사실을 중시하는 경향이 있다. 그러나 죽도(독도)의 활용사실을 확인할 수 있는 문헌이 처음 등장한 1640년대 이후의 문헌들을 검토해보면, 울릉도와 세트로 활용됐다고 제시되어 있다. 항해 기술의 문제로 20세기 초엽에야 이르러 비로소 오키섬에서 울릉도로 직접 왕래할 수 있었던 것이다. 죽도(독도)는 한국의 울릉도와 일본의 오키섬 사이에 존재하기 때문에 그 두 개의 큰 섬을 연결하는 동선 상에서 활용되고 있었다. 그 점에 유의한다면 죽도(독도)를 역사적으로 축적되어온 죽도(독도)의 특성을 무시하고 그 동선 상의 어느 한쪽만 갈라놓아 주장하는 것은 부적절하다는 생각이 든다.

『네 사중주』 와 기독교는 서로 밀접한 관계가 형성된다는 것은 주지의 사실이다. 이 연구는 특히 이 작품 전체의 주제를 포괄하고 있는 두 종류의 제사만이 담고 있는 독특한 특성에 대해서 고찰해 보았다. 그리고 그 의미가 네 사중주 전체에 어떻게 삼투되었는가를 조명했다. 제사가 중심을 잃은 현대인의 생활상에 대한 묘사를 나타내듯 엘리엇은 네 사중주 전체의 주제를 중심에서 이탈한 현대인들의 바른 중심 찾기로 일관하고 있다. 그 방법이 하나님과 완벽한 조화를 형성하는 것에 있다는 것이 본 연구의 결과이다.

The purpose of this study is to analyze the actual condition of the already established rural theme park, draw the weak and strong points, and come up with an efficient performance plan for Changwon Persimmon Theme Park through the benchmarking of the best overseas case. According to the analysis, it is necessary to introduce a facility and a program for family customers as a plan for promoting Changwon Persimmon Theme Park. It is required to secure safety through public operation and management, improve scalability of the facility through the establishment of multi-functional complex facility, and come up with a plan for operating a special program associated with local resources. Therefore, this study drew three activation factors: the establishment of operation and management system, the development of operation contents by facility, and the establishment of operation in each area. First, to establish the operation and management system, it is necessary to classify the organization of the theme park into the operation business area and into operation & management area by job function. Secondly, it is necessary to establish a special program in consideration of space and facility, suggest a differentiated plan for operation contents, and create a facility operation plan and program for Changwon Persimmon Theme Park. Lastly, to operate and manage Changwon Persimmon Theme Park smoothly, it is necessary to set the theme park space as open collaboration space which the local residents can share and participate in by avoiding the conventional administration-based business performance and operation. This study suggested the plan for establishing an operation and management system for Changwon Persimmon Theme Park and its operation, the establishment of a special program, a business performance strategy, and the use of internal and external spaces of the theme park.

본 연구에서는 유방촬영검사에서 사전조사 관전압과 실제조사 관전압 편차에 따른 원인분석을 유방압박 두께, 유방크기, 체질량지수와 연관하여 규명하고 개선책을 찾고자 하였다. 국민건강보험공단에서 실시하는 유방촬영 검진자 중 40세 이상 여자 377명을 대상으로 조사하였다. 유방촬영검사에서 상하방향촬영에 의한 영상을 참고하여 의료영상저장정보시스템으로 전송되어진 선량 보고서(dose report)의 파라메타 중 사전조사 관전압과 실제조사 관전압의 편차에 따른 유방압박두께, 유방크기, 체질량지수를 분석하였다. 결과로는 유방압박두께가 얇을수록, 유방크기가 작을수록, 체질량지수가 작을수록 관전압 편차가 크게 나타났다. 결론적으로 유방촬영검사에서 유방압박두께와 유방크기에 따른 관전압 설정을 하기 위해 우리나라 실정에 맞는 유방촬영기기의 최소 관전압이 재설정 되어야 할 것이며, 또한 유방압박두께가 얇은 환자나 유방크기가 작은 환자를 검사할 경우 정확한 조사조건 매뉴얼을 만들어 검사함으로서 촬영조건의 편차를 줄여 방사선피폭 경감과 좋은 영상의 화질을 만드는데 노력해야 할 것으로 사료된다.

The purpose of this research is to analysis actual condition of promoting complex industrialization and changes after promoting, and then to classify organic farmer using cluster analysis based on delineated organic farmer’s changes factors. This study also aims to investigate differences in socioeconomic characteristics and behavioral intentions among classified groups of organic farmer’s changes. Data were obtained by questionnaire. From the factor analysis, four factors were derived as “Economics”, “Public benefit”, “Environment and philosophical values” and “Establishing management and the regional bedrock”. From the cluster analysis, three cluster were derived as “group that has a positive awareness of promoting complex industry”, “group that has a negative awareness of promoting complex industry” and “unstable management and a regional base”. And the three classifications were significantly different in the satisfaction and behavioral intentions.

Drought is a reoccurring worldwide natural hazard that affects not only food production but also economics, health, and infrastructure. Drought monitoring is usually performed with precipitation-based indices without consideration of the actual state and amount of the land surface properties. A drought index based on the actual evapotranspiration can overcome these shortcomings. The severity of a drought can be quantified by making a spatial map. The procedure for estimating actual evapotranspiration is costly and complicated, and requires land surface information. The possibility of utilizing drone-driven remotely sensed data for actual evapotranspiration estimation was analyzed in this study. A drone collected data was used to calculate the normalized difference vegetation index (NDVI) and soil-adjusted vegetation index (SAVI). The spatial resolution was 10 m with a grid of 404 x 395. The collected data were applied and parameterized to an actual evapotranspiration estimation. The result shows that drone-based data is useful for estimating actual evapotranspiration and the corresponding drought indices.

Recycled aggregate is not used the structures due to the negative perception of the quality. Using only recycled aggregate concrete structures to improve these recognition were constructed to evaluate the mechanical properties and durability. The result is determined to be applicable to 100% recycled aggregate concrete in the structure.

In this study, the recycling processes of construction and demolition waste (C&D waste) were analyzed, and its national recycling rate was determined using material flow analysis (MFA). Available statistical data provided by Ministry of Environment and Korea Environment Corporation were used for the MFA study. The collected data were carefully examined and validated by field investigations. System boundary for MFA covered from waste generation from construction sites to final disposal in 2013. The field investigation showed that recycled aggregate is produced through mechanical shredding, separation, and screening processes of C&D waste. The production efficiency (or process yield) was estimated to be approximately 81.2% on average. The foreign materials in the waste accounted for 18.8% by weight. The separated impurities were sent to recycling facilities, incineration facilities, or landfill sites, depending on the physicochemical characteristics. Efficiency of recycling facilities and the statistical data were integrated to estimate the national actual recycling rate, which turned out to be 87.7% in 2013. Approximately 49.1% of the construction-related waste was recycled as recycled aggregate for concrete production and road base layer for asphalt pavement. Based on the result of MFA, there is 9.8% difference between the actual recycling rate in this study and reported recycling rate by national statistics. In the future, more various C&D waste treatment and disposal facilities, along with aggregate recycling facility, should be investigated to verify the actual recycling rate determined by this study. Statistical accuracy should be further refined through additional field investigations. Our findings can be applicable to development of recycling policies and best management practices for C&D waste streams.

This study is intended to prepare an revitalization plan of region where rural development project is completed through an analysis of the actual condition of facility operation and maintenance in the region where the project is completed. The results of survey of actual condition of facility operation in the region where rural development project was completed showed that the facilities were not self-sufficient in terms of operation and maintenance cost. Therefore, a prerequisite to the revitalization of region where the project is completed is to prepare an alternative plan for increasing the efficiency and applicability of currently already prepared facilities. Second, a project operation organization system should be streamlined and the competency of operation personnel should continue to be strengthened. Third, it is necessary to prepare a support system and establish cooperation networks for increasing the extensibility of project and continuing to induce community revitalization in the region where the project is completed in the future.

We estimated the orbit of the Communication, Ocean and Meteorological Satellite (COMS), a Geostationary Earth Orbit (GEO) satellite, through data from actual optical observations using telescopes at the Sobaeksan Optical Astronomy Observatory (SOAO) of the Korea Astronomy and Space Science Institute (KASI), Optical Wide field Patrol (OWL) at KASI, and the Chungbuk National University Observatory (CNUO) from August 1, 2014, to January 13, 2015. The astrometric data of the satellite were extracted from the World Coordinate System (WCS) in the obtained images, and geometrically distorted errors were corrected. To handle the optically observed data, corrections were made for the observation time, light-travel time delay, shutter speed delay, and aberration. For final product, the sequential filter within the Orbit Determination Tool Kit (ODTK) was used for orbit estimation based on the results of optical observation. In addition, a comparative analysis was conducted between the precise orbit from the ephemeris of the COMS maintained by the satellite operator and the results of orbit estimation using optical observation. The orbits estimated in simulation agree with those estimated with actual optical observation data. The error in the results using optical observation data decreased with increasing number of observatories. Our results are useful for optimizing observation data for orbit estimation.

건축물들의 화재와 안전사고 등의 철저한 관리와 불특정 다수인들의 피해를 예방하기 위하여 주요 시설물에 대한 점검, 유지, 관리교육 등 기존 건축시설물의 관리현황들을 조사ㆍ분석하였다. 그 결과는 1. 조직적인 측면에서 시설관리자들의 자발적인 재난예방과 재난수습의 원활한 추진을 위해서는 높은 통솔력과 지휘감독권이 절실히 요구된다. 그것은 시설관리자에게 실질적인 예산의 편성 및 운용을 할 수 있는 권한을 주고 또한 실무자에게도 맡은 부분에 관하여 책임과 권한을 주는 제도적 장치도 필요하다. 2. 인력적 측면에서 시설물의 관리자 대부분은 30대와 40대가 대다수를 차지하고 있고, 실무자는 30대(48％)에서 40대(24％)로 가면서 절반으로 줄어들었다. 관리자 및 실무자의 경력에 있어서도 7～10년 미만과 15～20년 미만의 분포가 낮은 것은 건축물의 시설관리의 전문 인력이 부족한 현상으로 실무자들이 현장에 남아서 정년을 맞을 수 있는 대책이 필요하다. 3. 시설관리자 및 실무자들의 근무 조건에서 시설관리자나 실무자 대다수는 근무형태가 불규칙한 근로 조건(71%)에서 근무하고, 급여의 조건도 미비하며 근무환경 역시 열악하였다. 따라서 이의 개선이 필요하며 현실적인 급여 등의 개선도 중요할 것이다. 4. 시설관리의 측면에서 시설물 관리자의 74%가 두 가지 이상의 시설관리업무를 수행하고 있고, 또한 넓은 관리면적을 담당하고 있었다. 이렇듯 시설물의 안전이나 충실한 관리 점검을 위해서도 관리자나 실무자들의 잡무 등은 줄여야 할 것으로 사료된다. 5. 교육의 측면에서 시설관리자들은 법정교육에 대해 89%가 상당한 도움이 된다고 하였다. 그러나 교육의 내용을 살펴보면 이론위주의 교육이 83％로 대부분을 차지하며, 시설관리현장에 바로 적용할 수 있는 실무위주의 교육은 17％밖에 되지 않아 아쉽다고 하였다. 이렇듯 실무교육시간의 확대가 필요하다.

본 연구의 목적은 교육용 치과 엑스선 발생장치를 설치 및 가동 중인 전국 치위생(학)과를 대상으로 방사선 작업종사자의 방사선 안전 관리 실태를 설문 조사하고 이를 체계적으로 추이 분석하여 교육용 치과 엑스선 발생장치의 안전한 이용 기반을 확립하기 위한 기초 자료로 제공하고자 하였다. 이를 위하여 교육용 치과 엑스선 발생장치의 방사선 안전 관리와 관계되는 원자력 관계 법령 및 국내 방사선 안전성 평가 및 규제 기술 개발 현황에 대한 용역 보고서를 참고하여 포괄적인 문헌 조사를 하였으며 이를 토대로 응답자의 일반적 특성, 방사선안전관리자의 위상, 방사선 안전관리 현황과 지식 및 의식 수준에 대한 설문지를 작성하였다. 본 연구는 국내 교육기관 내 방사선안전관리자와 교육용 치과 엑스선 발생장치를 운전 가능한 학사 및 실습 조교, 전임 교원 224명을 대상으로 설문 조사를 시행하여 설문 응답 누락 및 불충분한 응답을 제외한 95부를 회수하여 분석 자료로 이용하였다. 분석 방법은 일반적 특성 및 방사선안전관리자의 위상은 빈도와 백분율을 구하였으며 방사선 안전 관리 현황과 지식 및 의식 수준은 빈도 분석과 설문 문항별 연관성 분석을 위한 χ2 검정(chi-square test)과 수준간 연관성을 구하기 위한 피어슨 상관분석(Pearson correlation analysis)을 하였다. 결과적으로 교육용 치과 엑스선 발생장치의 운영은 대부분 대학 이상의 사회적 교육 수준이 높고 치위생학을 전공한 20대에서 40대의 여성이 담당하고 있었으며 남성과 비교하여 방사선 안전 관리에 대한 의식 수준이 높게 나타났으며 통계적으로 유의한 선형적 관계를 보였다(χ2 >5, 0.1<r<0.3, p<0.05). 또한 국가 기술 면허의 보유는 치과위생사가 55.4%로 가장 많았으나 방사성동위원소 취급자 일반 면허자(28.2%) 또는 방사선사 면허자(16.4%)와 비교하여 방사선 안전 관리에 대한 의식 및 지식 수준이 낮게 나타났으며 통계적으로 유의하게 뚜렷한 선형적 관계를 보였다(χ2 >5, 0.3<r<0.7, p<0.01). 특히 업무 경력이 증가할수록 방사선 안전 관리에 대한 지식은 높게 나타났으나 의식 수준은 감소하는 것으로 분석되었다(χ2 >5, 0.3<r<0.7, p<0.01). 따라서 방사선 안전 관리에 대한 전문적 지식 체계의 확립과 국내 외 방사선 안전 관리 체계를 포괄적으로 이해할 수 있는 제도화된 개선책 마련이 시급할 것으로 판단되었으며 교육용 치과 엑스선 발생장치의 사용에 따른 방사선작업종사자와 주변 일반인의 방사선 위해로부터 방어를 위한 체계적인 방사선 안전 관리 지침서의 개발이 필요하다고 판단되었다.

The objectives of this research was to evaluate the anaerobic digestibility of waste activated sludge (herein after WAS)and waste beverages (herein after WB) in beverages manufacturing industry using actual plant under various conditions.In this study, anaerobic digestion with WAS and WB were evaluated according to different operating conditions. As thebasis operating conditions for anaerobic digestion, the reaction temperature was controlled at 35 and hydraulic retentiontime 30 days.
