The era of today's day is that the era of the black gold age is now approaching the era of the blue gold age. As the importance of water increases, support and policies for the water industry are presented. The water industry is a public service industry but it faces the problem for unbalanced supply between users. One of solutions for solving the problem at hand is the privatization of the public service and it is the most sensitive and focused subject to the issue. Korea is also coming up for the privatization of the water industry. So, one of the privatization operations based on the privatization of the current waterworks law is management contract by the specialized organization and it is in progress to enhance the efficiency of public services. Therefore, this study aims at finding out the local water supply services' efficiency by K-Water using DEA(Data Envelopment Analysis), and productivity analysis by malmquist index on 18 organizations of the implementation of local water supply management contract using the date from 2012 to 2014. According to the result of the DEA, 10 of the 18 organizations were the most efficient during 3 years and malmquist index for analysing the productivity was decreasing. That is because of the leakage ratio and utilization ratio of the raw water and both of them are significant to productivity. As a result, this study differs from the previous studies by analysing efficiency and productivity using DEA and malmquist index to the solution for the problem faced by current water industry.

The direct metal laser sintering (DMLS) technique would be promising for the full-arch implant-supported restorations due to reduced cost and manufacturing time without potential human errors and casting defects. The aims of this case report were to describe the successful outcome of an implant-supported fixed dental prosthesis in the edentulous maxilla by using the DMLS technology and computer-aided design and computer-aided manufacturing (CAD/CAM) monolithic zirconia crowns, and to describe its clinical implications. A healthy 51-year-old Korean woman visited Seoul National University Dental Hospital and she was in need of a rehabilitation of her entire maxilla due to severe tooth mobility. In this case, all maxillary teeth were extracted and an implant-supported fixed dental prosthesis was fabricated that involved a cobalt-chromium (Co-Cr) framework with the DMLS technique and CAD/CAM monolithic zirconia crowns. Six months after delivery, no distinct mechanical and biological complications were detected and the prosthesis exhibited satisfactory esthetics and function. In this case report, with the DMLS system, the three-dimensional printed prosthesis was created without additional manual tooling and thus, reliable accuracy and passive fit were obtained. 직접식 금속 레이저 소결 방식 시스템은 기공 오차 및 주조 결함 없이 제작 비용 및 제조 시간 단축을 장점으로 전악 임플란트 지지 고정성 보철물 제작에 유용하다. 본 증례에서는 직접식 금속 레이저 소결 방식과 치과용 캐드캠으로 제작된 단일구조 지르코니아 크라운을 사용하여 무치악 상악에서 임플란트 지지 고정성 치과 보철물의 성공적인 결과를 보고하고 임상적 의의를 평가하였다. 51세의 건강한 중년 여성이 상악 전 치아의 동요도를 주소로 서울대학교 치과병원에 내원하였다. 모든 상악 치아 발치 후 직접식 금속 레이저 소결 기술 및 캐드캠 단일구조 지르코니아 크라운을 사용하여 코발트-크롬 프레임을 포함하는 임플란트 지지 고정성 치과 보철물을 제작하였다. 최종 수복물 장착 6개월 후, 기계적 및 생물학적 합병증은 발견되지 않았고 보철물은 기능 및 심미적으로 만족스러운 결과를 보였다. 직접식 금속 레이저 소결 시스템을 이용하여 추가적인 기공 작업 없이 임플란트 지지 고정성 보철물을 제작하여 제조 시간을 단축하고 신뢰할 수 있는 정확도와 적합성을 얻었다.

When considering the long-term safety assessment of spent-nuclear fuel management, americium is one of the most radio-toxic actinides. Although spectroscopic methods are widely used for the study of actinide chemistry, application of those methods to americium chemistry has been limited. Herein, we purified $^{241}Am$ to obtain a highly pure stock solution required for spectroscopic studies. Quantitative and qualitative analyses of purified $^{241}Am$ were carried out using liquid scintillation counting, and gamma and alpha radiation spectrometry. Highly sensitive absorption spectrometry coupled with a liquid waveguide capillary cell and time-resolved laser fluorescence spectroscopy were employed for the study of Am(III) hydrolysis and oxalate (Ox) complexation. $Am^{3+}$ ions under acidic conditions exhibit maximum absorbance at 503 nm, with a molar absorption coefficient of $424{\pm}8cm^{-1}{\cdot}M^{-1}$. $Am(OH)_3(s)$ colloidal particles formed under near neutral pH conditions were identified by monitoring the absorbance at around 506-507 nm. The formation of ${Am(Ox)_3}^{3-}$ was detected by red-shifts of the absorption and luminescence spectra of 4 and 5 nm, respectively. In addition, considerable enhancements of the luminescence intensities were observed. The luminescence lifetime of ${Am(Ox)_3}^{3-}$ increased from 23 to 56 ns, which indicates that approximately six water molecules are replaced by carboxylate ligands in the inner-sphere of the Am(III). These results suggest that ${Am(Ox)_3}^{3-}$ is formed through the bidentate coordination of the oxalate ligands.

Solid papillary carcinoma of the breast is a distinctive form of intraductal papillary carcinoma frequently associated with both mucinous carcinoma and infiltrating ductal carcinoma, not otherwise specific. To our knowledge, this case is the first description of the cytologic aspects of solid papillary carcinoma of the breast in the Korean literature. We experienced a case of solid papillary carcinoma of the right breast diagnosed by fine needle aspiration cytology(FNAC) in a 70-year-old female. FNAC from the right breast showed high cellularity consisting of mostly tight clusters of tumor cells and a few scattered tumor cells. The nuclei were monotonously round to oval in shape with inconspicuous nucleoli. The cytoplasm was abundant and finely granular. Scant amount of mucinous material was present on the background. The diagnosis was confirmed histologically and immunohistochemically.

Cluster analysis with meteorological data allows to segment meteorological region based on meteorological characteristics. By the way, meteorological observed data are not adequate for cluster analysis because meteorological stations which observe the data are located not uniformly. Therefore the clustering of meteorological observed data cannot reflect the climate characteristic of South Korea properly. The clustering of $5km{\times}5km$ gridded data derived from a numerical model, on the other hand, reflect it evenly. In this study, we analyzed long-term grid data for temperatures and precipitation using cluster analysis. Due to the monthly difference of climate characteristics, clustering was performed by month. As the result of K-Means cluster analysis is so sensitive to initial values, we used initial values with Ward method which is hierarchical cluster analysis method. Based on clustering of gridded data, cluster of meteorological stations were determined. As a result, clustering of meteorological stations in South Korea has been made spatio-temporal segmentation. 기상자료를 이용한 군집분석은 기상 특성에 근거한 기상 지역의 세분화를 가능하게 하고 군집을 이루는 지형별 기상 특성의 파악을 용이하게 한다. 이때 기상관측자료를 이용한 군집분석은 관측지점의 밀도가 다르기 때문에 우리나라의 기상특성이 고르게 반영되지 못할 수 있다. 반면 수치모델 격자자료는 $5km{\times}5km$ 간격으로 조밀하고 고른 자료의 생산이 가능하므로 우리나라의 기상 특성을 고르게 반영할 수 있다. 본 연구에서는 기온과 강수량의 수치모델 격자자료를 이용하여 군집분석을 수행하고, 그 결과를 바탕으로 기상관측지점에 대한 군집을 결정하였다. 기상 특성이 월별로 상이할 수 있기 때문에 군집분석은 월별로 수행하였으며, K-Means 군집분석 방법의 단점을 보완하고자 계층적 군집분석 방법인 Ward 방법과 결합하여 적용하였다. 그 결과 우리나라 기상관측지점들에 대해 시 공간적으로 세분화된 군집화가 이루어졌다.

Ganglioneuroma is a well-differentiated, benign tumor of the sympathetic nervous system. These tumors belong to a family of neoplasm that exhibit a wide range of differentiation, with neuroblastoma at one end and ganglioneuroma at the other. Because it share morphologic features with other both benign and malignant neural tumors, accurate preoperative diagnosis is often difficult. Nonetheless, it is critical for proper management. Fine needle aspiration cytology (FNAC) in the diagnosis of the ganglioneuroma has been a little documented. We describe a case of mediastinal ganglioneuroma in a 33-month-old girl. The diagnosis was suggested on FNAC and was confirmed by histopathologic examination later.

Synovial sarcoma is a rare soft tissue tumor accounting for 5-10% of soft tissue sarcomas. Most arise in the extremities and trunk, and a small proportion occur in the abdominal wall, head and neck legion, and mediastinum. It manifests different phenotypic subtypes that render their cytologic evaluation challenging. Moreover, cytomorphologic description of the epithelial component of synovial sarcoma is rare in Korea. We report a case of biphasic synovial sarcoma on the right lower extremity in a 49-year-old woman diagnosed by fine needle aspiration cytology. The aspirate was moderately cellular and composed of a mixture of tissue fragments and dissociated cells with bland chromatin, inconspicuous nucleoli, and oval to spindle-shaped cytoplasm. Mitosis was rare. A monolayer sheet of epithelial component was seen. The cells in this monolayer sheet had more abundant distinct cytoplasm, round nuclei, and prominent micronucleoli. Histologic examination showed a biphasic pattern consisting of mostly sarcomatous stroma and a few small glandular areas at the periphery of the tumor.

상관적분 기법의 프랙탈 차원 추정을 통한 기후관측소 밀도 분석에 관한 연구

김희경,이영섭,Kim, Hee-Kyung,Lee, Yung-Seop 한국데이터정보과학회 2013 한국데이터정보과학회지 Vol.24 No.1

현재 세계기상기구에 등록되어 있는 우리나라 기후관측소는 11개 지점이다. 11개 지점의 분포를 보면 지리적으로 균일하지 못하고 대부분이 해안에 위치하는 편중된 분포를 보이고 있다. 따라서 기후관측소 자료를 바탕으로 하는 전국 기후자료 생산 및 특성 산출을 위해서는 관측소 밀도에 관한 분석을 통해 기후자료 분포에 대한 균형도의 측정이 필요하다. 본 연구에서는 상관적분 기법을 이용한 프랙탈 차원의 추정을 통해 우리나라 기후관측소 밀도를 측정하였다. 상관적분 기법 적용시 회귀분석을 통하여 추정된 회귀계수로 프랙탈 차원을 추정한다. 추정된 프랙탈 차원을 이용해 전국의 기상관서들 중 지리적으로 기후관측소 구성의 균형도를 가장 높여 줄 수 있는 기후관측소 후보지점을 선정하였다. 이 때 후보지점을 순차적으로 선택하는 방식과 조합의 형태로 여러 후보지점을 한 번에 선택하는 방식으로 각각 최적의 후보지점들을 선택하였다. Currently we have 11 climatological stations registered in World Meteorological Organization. Geographically, these stations are unevenly distributed in Korea and are mainly located on seaside. Therefore station's density analysis should be performed to produce the high-quality climatological data. Using the correlation integral method, the density of climatological stations can be measured by the estimation of fractal dimension. In this study, new climatological stations having the higher fractal dimension were selected. Sequential or simultaneous selection method were carried out until 3 new stations were selected based on the fractal dimension.
