To study vegetational structure of the Korean warm temperate region fifty two plots were surveyed in evergreen broad-leaved forests of southern islands. The vegetational structures among sites were dissimilar in virtue of geographical isolation and artificial disturbance. The surveyed plots were generally classified into three groups; the first, the group in which plant succession has proceeded naturally, the second, the group which was disturbed and managed for a long time, the third, the group which was afforested and has been succeeded into evergreen broad-leaved forest. The species with constancy over 80% in fifty two plots were Machilus thunbergii, Eurya japonica, Trachelospermum asiaticum var. intermidium, Cinnamomum japonicum, and Ligustrum japonicum. The community of Lozoste lancifolia, which is assumed to be a climax community of the Korean warm temperate region, remains in Chudo and Aedo. The secondary succession of seashore forest which were disturbed in the past will be done into Castanopsis cuspidata var. sieboldii

최근 기상이변의 영향으로 강우량의 변화가 심해지고 있으며 지역별 계절별로 그 편차가 커지고 있다. 이는 수자원 이용의 측면에서 개발과 이용 및 관리에 많은 어려움을 주고 있으며 향후 변화하는 수자원 이용량에 대응하기 위해서는 변화하는 강우에 대한 지표수 및 지하수 등의 수자원확보량 분석이 필요하다. 지표수의 경우 기후변화에 의한 영양에 대하여 많은 연구들이 이루어 지고 있으나 지하수는 많은 곳에서 이용되고 일부 도서 및 해안지역에서는 유일한 수자원 공급책으로 이용되고 있음에도 불구하고 이에 대한 연구가 미흡한 실정이다. 따라서 본 연구에서는 부산광역시 수영구를 포함하는 광역 지하수유역에 47년간의 강우량 자료를 10%, 20% 증감시켜 지하수함양량을 산정하고 강우량 증감에 따른 변화 특성을 분석하였다. 대상지역의 지하수함양량은 실제 강우 시에는 1970년에 408.9mm로 가장 크게 나타났고 1988년에 73.8mm로 가장 작게 나타났으며 평균 215.4mm로 나타났다. 강우 10% 증가 시에는 1972년에 466.4mm로 가장 크게 나타났고 1988년에 97.8mm로 가장 작게 나타났으며 평균 248.5mm로 나타났다. 강우 20% 증가 시에는 1970년에 512.0mm로 가장 크게 나타났고 1988년에 115.1mm로 가장 작게 나타났으며 평균 280.8mm로 나타났다. 강우 10% 감소 시에는 1970년에 358.6mm로 가장 크게 나타났고 1988년에 57.7mm로 가장 적게 나타났으며 평균 182.0mm로 나타났다. 강우 20% 감소 시에는 1970년에 308.9mm로 가장 크게 나타났고 1988년에 42.0mm로 가장 작게 나타났으며 평균 149.4mm로 나타났다. 실제 강우량에 대비한 10%와 20% 강우 증감시의 지하수함양량 변화율을 살펴보면 강우 10% 증감 시는 약 1~3%의 변화율을 보였으며 강우 20% 증감 시는 약 3~6%의 변화율을 보였다. 또한 모든 강우 증감 상태에서 전체적으로 변화율이 감소하는 추세를 나타냈으며 도시화가 급격하게 이루어진 1985년을 기준으로 이후 변화율이 큰 폭으로 감소하는 것을 알 수 있었다.

This research provides an empirical analysis of the academic libraries' operating performance in Seoul, Korea. This study aims to find the key variables and the impacts of each variables on the operating performance of the academic library to attain competitiveness and long-term conditions for enhancing customer satisfaction. Specifically, this research focuses on the library's circulation service performance. The author try to analyze the relationship between the characteristics of the library (space, number of employees, number of books, budget) and the circulation performance. Korea Libraries Association have published yearly-book on the Korean library's circumstances and statistics. Yearly-book contains the data about the spaces, number of books, number of workers, the library's budget scales and other unique elements. This study finds that the circulation performance of books is positively related with the size of physical space, number of books holdings, and budgets (hypothesis 1, 3 and 4 accepted). This study demonstrate that the characteristic elements of academic library can be influential factor of the library performance.

Cost Estimate for alternative in design phase of construction become criterion for profitability and feasibility analysis of projects. Initial design phase performed schematic estimate based on similar data in the past. The quantity take-off according to estimators experience and calculation method are occurred different or missing. IT (Information Technology) technology evolution has been promoting BIM technology in construction. It is changing the paradigm of planning, design, construction and maintenance phase throughout the construction project. A number of studies have been attempted to apply BIM technology in the construction. In this paper, we propose schematic estimation framework linking standard format IFC (Industry Foundation Classes) and estimate related knowledge. As a result, it performs a cost prediction for decision-making in the design phase, and expected to overcome the limitations of previous studies. In addition, it is possible actively coping with changes.

Acquisition processes in public libraries, especially as influenced by policies and regulations both in national and regional levels have not been in the main area of concerns in the research of library and information science. While the area of collection management has yet been one of the major issues in this filed, public library book-purchasing in the major factor to achieve effective library collections. This study concentrated on the policies and regulations that attempts to normalize and control the acquisition process in public libraries. This research analyzed and investigated (1) various policies and regulations regarding the library collection as public procurement, (2) legitimacy of decision between normal price procurement and discounted price contract under the current policy on normal retail price of books, (3) budget allocation, (4) policies on library acquisition processes. Suggestions are also added for the efficient collection building in public libraries.

In order to understand the trends of collaborative research in the field of Library and Information Science (LIS) in Korea, this study analyzed bibliometric data and keywords of 5,383 Journal papers by 195 Korean LIS professors from 2000 to 2017 as well as the author credit allocation formulas of 26 Korean university research evaluation criteria. Examination of university research evaluation criteria revealed co-authors' credit level to be generally much lower than that of single authors, which in turn reduces the relative value of collaborative research. As a result, recent journals publish more co-authored papers than single author papers both domestically and internationally. The study also found collaborative research to be less prevalent in private universities than national universities and least prevalent in associate professors among professors. Furthermore, keyword analysis of study data revealed the emerging topics of both domestic and international collaborative research to be those that reflect social phenomena as well as those that relate to information science employing new technologies.
