뉴욕공공도서관(The New York Public Library)은 전문분야로 특화된 대학원 수준의 4개의 연구도서관과 85개의 지역분관을 가리키는 복합관의 총칭이다. 뉴욕시는 인구 800만의 5개의 행정구역으로 이루어지는데, 뉴욕공공도서관은 맨해튼, 브롱크스, 스태튼섬의 3개지구 330만명을 서비스 대상으로 하고, 나머지 2개 지구를 브루클린공공도서관, 퀸즈공공도서관이 관할한다. 연간 예산은 2억8천만달러에 달하며, 2003년의 통계에 따르면 방문이용자가 150만명, 홈페이지 이용자도 1,000만명에 이른다고 한다. 놀라운 것은 운영이나 규모면에서 세계 제일로 손꼽히면서도 공립(公立)이 아니라 비영리민간단체(NPO)가 운영하는 공공(公共) 도서관이라는 것이다. 뉴욕공공도서관은 설립부터 독지가들이 기부 등을 통해 도서관 활동에 깊이 관여하면서 행정과의 독특한 협력관계를 발전시켜왔다. 이러한 전통에 의거한 퍼블릭 프라이빗 파트너십(Public Private Partnership)은 뉴욕공공도서관의 핵심으로 보다 풍부한 서비스의 제공을 가능하게 하였다. 이에 본 연구는 우리나라와 달리 예산확보를 위한 경비가 일정부분 상정되고 있는 뉴욕공공도서관의 자금조달 비즈니스 모델에 대한분석에 중점을 두었다.

남해안의 중부에 위치한 삼천포 근해의 진주만과 자란만 등은 경남 사천군, 남해군 및 고성군에 접해있으며, 만 주변에는 여러 개의 섬이 산재해 있는 반폐쇄적인 만이다. 진주만의 안쪽에는 사천만이 위치해 있으며, 윗쪽은 남강의 하류 지역이다. 일반적으로 동물성 부유생물은 식물성 부유생물에 의해 합성된 유기에너지를 어류와 같은 더 높은 영양 단계로 전달하는 일차 소비자의 역할을 담당하며, 동물성 부유생물의 분포는 다양한 해양 생태 환경에 영향을 받는다. 동물성 부유생물은 피식과 종간 경쟁같은 생물적인 요인(Parsons et al., 1984)뿐만 아니라, 유영 능력이 미약하기 때문에 수온, 염분같은 물리적인 특성에 의해서도 영향을 받는다(Barlow, 1955; Lance, 1963).

A breeding pair of the Black-faced Spoonbill Platalea minor was firstly recorded on Chilsando Islands, Younggwang, Jeollanamdo Province in 1991. Since the mid 2000s, breeding population on the breeding sites has gradually increased. This study was conducted to identify breeding status and nest site characteristics of the species from May to August, 2013 on Chilsando Islands. We recorded number of nests, length and width of the nest base, slope around the nests, nest materials, distances from the nearest nest, presence of nest cover and nesting area. In 2013 breeding season, 25 of 49 nests produced at least one successful fledging. A total of 55 youngs were successfully fledged and number of fledging per nest was 2.20 individuals. Nesting area was $77.8m^2$ and $93.4m^2$ for Sansando and Yuksando Islet, respectively. Soil and soil mixed with tree root were preferred for substrate of nest base over rock and Brassica napus was dominantly selected as nest materials by Black-faced Spoonbills. Nest characteristics of 22 nests in Sasando and Yuksando Islet varied $49.59{\pm}6.53cm$(mean${\pm}$SD) for length of nest base, $41.00{\pm}5.82cm$ for width of nest base, $20.85{\pm}9.96^{\circ}$ for slope above the nest, $34.09{\pm}17.75^{\circ}$ for slope below the nest and $130.82{\pm}84.17cm$ for distances from the nearest nest. Fifteen pairs (68.2%) occupied where nest cover existed. Nest cover were located in front of the nest for 5 pairs, back of the nest for 9 pairs and both front and back of the nest for 1 pair.

The following study was conducted to determine the optimal location in terms of efficiency for solar energy facilities, and to propose a policy implications for the orientation of the installments. 92 cases in Jeollanam-do Province were selected. A regression analysis was performed between the average electricity generation time as the dependent variable, and the facility, weather and site conditions as the independent variables. As a result, 5 variables were deemed significant. Larger site areas, closer proximity to rivers, islands, oceans, etc., least south-oriented, higher average wind speed, and facilities in agricultural land use and natural environment conservation land use had the highest efficiency. This study minimized the possibility of secure databases and errors following facility types, and was limited in the number of sites studied, since this was only conducted in Jeollanam-do Province. Nevertheless, these conclusions still offer important policy implications for determining the most optimal location for solar energy facilities.

Based on the DGPS radio wave measurement in the coast of the yellow-sea, south-sea and east-sea, the DGPS service regions in the korean coastal ferry route are analyzed in this paper. The impact of obstacles on the propagation due to the archipelago and island regions are measured and analyzed in the point of service region. The ocean-based DGPS reference stations provide the wide DGPS ocean service regions with signal strength more than $40dB{\mu}V/m$ and signal-to-noise ratio more than 10 dB. Based on the overlapping of the service regions between the DGPS reference stations, the DGPS services with good quality are provided in the coastal ferry route segments. In case of regions where the propagation obstacles are scattered, the increasingly good service can be provided under conditions of output power reinforcement and antenna efficiency enhancement.

This study is to analyse Korean map inserted in the "Gwandong Gwanseo-jido(關東 關西地圖)" which is reserved in the Gyujanggak Archives as the mother edition of Korean Map("朝鮮圖") in Kangxi Atlas made in Qing dynasty. Map in Gyujanggak is very similar to the Korean map in the Kangxi atlas in terms of shape of southern part of Korean peninsula, boundary of provinces. Especially over 80% of place names on two maps are coincident and over 90% of islands names are identical. It is revealed that map in the Gyujanggak Archive is the most similar map to the Kangxi Atlas in Korea. This map was produced in 1729~1736 which is late compared to the Kangxi Atlas. This difference of production period shows that mother editon of map in Gyujanggak is the base map of Korean Map in Kangxi atlas. The similarity and differences between those maps show the process of edition of geography in the produce the Kangxi atlas. And map in Gyujanggak shows that production of new type of Korean whole map was began in the late $17^{th}$ century.

This study was carried out to define the characteristics of the identified ground-dwelling invertebrate communities at Nari basin and Tonggumi area in Ulleungdo Island, designated as a nationally important agricultural heritage. The habitat types were divided into the following categories: crop land, forest, and ecotone, and the soil-dwelling invertebrates were collected according to habitat type. The ground-dwelling invertebrates were collected using a pitfall trap, and a self-organizing map (SOM) was applied to the invertebrates dataset to define the characteristics in invertebrates distribution. The SOM clearly classified the relevant information into four clusters, and extracted ecological information from the invertebrates dataset. The cluster II was composed of invertebrate communities which are collected in the Tonggumi area. The Tonggumi area is where mountainous areas were developed for agricultural purposes, which has geographical features commonly observed in Ulleungdo Island. It is noted that the cluster II has different characteristics as compared other clusters. The results of this study are expected to be used for the preservation of agricultural environment and maintenance of biodiversity by providing basic data, on the biotope of Ulleungdo Island designated as a nationally important agricultural heritage and information on the characteristics of the applicable ground-dwelling invertebrate communities.

The purpose of this study is to investigate the potential water condition of Honam region according to water budget analysis. For this purpose, the eight regions (Suncheon, Gwangju, Jhangheung, Damyang, Mokpo, Yosu, Huksando, Namwon) are selected as study area. The result is as follows. (1) The water surplus indicating the potential water condition is ordered as Yosu, Sunchon, Changhung, Namwon, Damyang, Huksando, Kwangju, Mokpo. So the potential water condition of Kwangju and Mokpo is worst among study regions. (2) The high water surplus region is corresponded to high precipitation and low actual evapotranspiration legions. (3) The potential water condition is to agree with several facts about the water resource condition of Honam region. For example, large scale dam of Honam region has been constructed for Kwangju and Mokpo city. This fact indicates that the potential water condition calculated by water budget analysis is corresponded to actual water resource condition. (4) Consequently, the water budget analysis is effective method for investigating the actual water condition and establishing the water resource management of specific regions.

The gold-silver deposits in the Casado district were formed in the sheeted and stockwork quartz veins which fill the fault fractures in volcanic rocks. K-Ar dating of alteration sericite (about 70 Ma) indicates a Late Cretaceous age for ore mineralization. These veins are composed of quartz, adularia, carbonate, and minor of pyrite, sphalerite, chalcopyrite, galena, Ag-sulfosalts (argentite, pearceite, Ag-As-Sb-S system), and electrum. These veins are characterized by chalcedonic, comb, crustiform and feathery textures. Based on the hydrothermally altered mineral assemblages, regional alteration zoning associated with mineralization in the Gasado district is defined as four zones; advanced argillic (kaolin mineral-alunite-quartz), argillic (kaolin mineral-quartz), phyllic (quartz-sericite-pyrite) and propylitic (chlorite-carbonate-quartz-feldspar-pyroxene) zone. Phyllic and propylitic zones is distributed over the study area. However, advanced argillic zone is restricted to the shallow surface of the Lighthouse vein. Compositions of electrum ranges from 14.6 to 53.7 atomic % Au, and the depositional condition for mineralization are estimated in terms of both temperature and sulfur fugacity: T=245。$~285^{\circ}C$, logf $s_2$=$10^{-10}$ ~ $10^{-12}$ Fluid inclusion and stable isotope data show that the auriferous fluids were mixed with cool and dilute (158。~253$^{\circ}C$ and 0.9~3.4 equiv. wt. % NaCl) meteoric water ($\delta^{18}$ $O_{water}$=-10.1~8.0$\textperthousand$, $\delta$D=-68~64$\textperthousand$). These results harmonize with the hot-spring type of the low-sulfidation epithermal deposit model, and strongly suggest that Au-Ag mineralization in the Gasado district was formed in low-sulfidation alteration type environment at near paleo-surface.

To enhance the grade and recovery rate of the gold/silver ores which yield at Philippine Mankayan mine, we studied the characteristics which are the geologic and mineralogical features of gold and silver ore, the liberation by crushing and grinding, the separation by sieving and shaking table. Gold/silver ore is composed of the sulfide minerals like pyrite, sphalerite, galena; and the gangue minerals which is quartz, clay. Gold/silver element are mainly contained in a sulfide minerals like pyrite, sphalerite and galena. To increase the liberation rate of sulfide minerals containing gold/silver element, the gold/silver ore has to be grounded under $100{\mu}m$ very finely because the crystal size of sulfide minerals is distributed from $1{\mu}m$ to $100{\mu}m$. The liberation rate of gold/silver ore increases to 92% when the particle size ($d_{90}$) of ore is grounded below $100{\mu}m$ by jaw crusher $\to$ cone crusher $\to$ rod mill by steps. The grade and recovery of sulfide minerals could not be enhanced by sieving separation because those crystal size is distributed homogeneously below $100{\mu}m$. But, when we separated the sieved ore using shaking table, the gold and silver grade increased to 40 ppm and 140 ppm, respectively. Then the recovery rate of gold reach almost 100% but that of silver is no more that 50%.
