This paper analyzes the duration of the construction document (CD) phase of 42 large public building projects delivered by the total solution service of Public Procurement Services in Korea from 2009 to 2014. The quality of construction documents significantly affects the quality of construction and facility management. Thus, securing appropriate time for the CD phase during project planning is important for the quality of a project. Currently, the duration of the CD phase is planned based on the construction costs of a project following a notice of the Ministry of Land, Infrastructure and Transport. However, our analysis results showed that the correlation between the actual duration of the CD phase and construction costs is very weak. The actual CD phase takes 1.33-1.79 times longer than the planned duration. The practitioners who were interviewed, were already aware that the correlation between the duration of the CD phase and the construction costs is weak. They identified the complexity of the project, the extent of the design changes, project type, client characteristics, and others as more influential factors on the CD phase than the construction costs. To improve the quality of CDs, a new guideline for determining an adequate CD phase duration should be studied and developed.

This study analyzed the status of the naturalized plants in islands in Jeollanamdo from an island biogeographic perspective. As a result of a floristic analysis at 47 inhabited islands and 194 uninhabited islands, 30 families and 134 species naturalized plants are reported. The most commonly occurring naturalized plant from 141 islands was Rumex crispus. The average number of naturalized plants by islands is 20.6 species (${\pm}14.22$) at the inhabited islands and 3.7 species (${\pm}3.89$) at the uninhabited islands. Presence of fifty nine naturalized species at Geumodo in Yeosu-si is the largest in number. The naturalization ratio, which is the ratio of naturalized plants to native plants, is 7.66% (${\pm}3.96$) in the inhabitable islands and 4.97% (${\pm}3.70$) in the uninhabitable islands. The naturalization ratio among islands of the West Sea in Jeollanam-do is 5.92% (${\pm}4.49$), and it is higher than 4.96% (${\pm}2.15$) in islands in the South Sea. Especially, the naturalization ratio at the inhabitable islands, i.e., 8.39% (${\pm}4.37$) at the islands of the West Sea is higher than 5.80% (${\pm}1.41$) at islands in the South Sea. The naturalization ratio of naturalized plants at the islands shows positive correlation with the size of the island (r=0.412, p<0.01), but the correlations with distance from the mainland and altitude above sea level are not significant. Eight ecosystem disturbing species designated by law are reported, and each species shows distinct distributional ranges. The regional differences in the number of naturalized plant species seem to be a result of the complex reflection of natural and human environmental factors, such as the degree of traffic between mainland and islands, degree of cultivation activities, along with the physical environmental differences. Since islands have limited habitats and resources, islands could be more vulnerable to the incoming species from outside, and environmental changes than mainland. Therefore, continuous monitoring and management against the naturalized plants in islands are needed.

지금까지 빗물에 대한 일반인들의 인식은 모두 치수에 중심을 두어왔다. 즉, 빗물은 내리자마자 곧바로 하수도를 통해 방류수역으로 신속하게 배제해야한다 것에만 관심을 두어 왔던 것이다. 이러한 문제점을 해결하기 위해 빗물을 버리고 배제하기보다 필요한 곳에서 집수하여 활용하거나 적절히 침투 또는 저류하여 물을 효과적으로 제어 관리해야할 필요성이 대두되고 있다. 안정적인 수자원 확보 및 공급에 대한 사회적 요구가 증가됨에 따라 대체방안으로서의 빗물이용관리가 제기되고 있으며, 이는 도시화 및 인구의 도서집중, 경제활동의 고도화 등 물 사용량이 증대되는 생활방식에 따라 물 공급 중단에 따른 피해 잠재성이 증가되고 있음을 의미하기도 한다. 본 과제에서는 이러한 필요성을 감안하여 대체수자원으로서의 빗물을 이용한 수자원 확보방안에 대해 연구하고, 스마트 워터그리드 관점에서의 빗물이용방안을 제시하여 그 적용성을 평가하고자 한다. 본 연구를 수행하기 위해서는 기존 대체수자원의 확보기술을 조사하고, 이를 바탕으로 다양한 수원을 통한 수자원 확보방안을 제시하고, 이 중 빗물을 이용한 수자원 확보방안에 대하여 스마트워터그리드 관점에서의 적용성을 평가하였다. 스마트워터그리드 내에서의 빗물이용을 통한 대체수자원 적용성 평가는 도서지역의 제한급수 등 물 부족 문제 해결을 위한 방안과 산간 농업지역에서의 물부족으로 인한 농작물 생산활동의 저하문제를 해결하기 위한 방안을 제시하였다. 또한 수자원확보를 위한 적정 빗물이용법 도출을 위해 최근 물 관리 패러다임의 변화를 고려한 정책사업으로의 접근, 중앙정부와 지방정부의 노력, 정부-민간 협동체계 구축을 위한 지역전문가의 활동방법 등을 제시하고자 한다. 본 연구의 결과 스마트워터그리드 체계구축을 위한 여러 요소기술 중 다중수원을 통한 용수확보 방안에서 빗물(우수)을 이용한 대체수자원 확보방안을 정립하고, 이를 이용하여 도서지역에서의 제한급수문제 해결방안과 산간 농업지역에서의 농업용수 확보방안을 제시할 수 있을 것이다.

The purpose of this study was to analyze the food service management practices and productivity in 49 elementary schools in the Daegu and Gyeongsangbuk-do areas. Survey questionnaires were used to obtain a variety of quantitative and qualitative information, including general food service management and productivity, on elementary school food service systems. Descriptive analysis, $\div$2-test, t-test and one-way ANOVA analysis were used as the statistical methods in this study. Eighteen elementary schools were located in urban areas, 13 in provincial areas and 18 in isolated areas. The average number of meals was 565.1, with a significant difference (p＝0.001) between the areas. The average cost per a meal was 1151.0 Won, with a significant difference (p＝0.001) between the areas. The productivity Index (meal/hour) was 13.5, with a significant difference (p＝0.001) between the areas. There was a significant positive correlation of the productivity Index between the total number of meal, the number of employees, the total food cost, meals per employee and the employee's working period. There was a significant negative correlation between the productivity Index and the number of side dishes, the lost per meal, the labor cost per meal and the employee's job satisfaction degree index (JDI).

This study attempt to suggest a policy for the effect of using in the public libraries by the verification that are different between groups by their using patterns and types of book collections. by using patterns and system of desired-book for user. by using patterns and system of desired-book for user. The questionnaire is distributed to the delivery lending library's user and librarian in public libraries. The summary of results are as follows 1 The Circulation period of public library is one month per every delivery lending library. 2. The Circulation volume of public library is '100-200' books per every times. 3. There are significant differences by their using patterns and types of book collections. 4. There are significant differences by their using patterns and system of desired-book for user. 5. There are significant differences by their using patterns and placement of book collections. Their results show that library is most effective place of book collection services. 6. Circulation services must carry out only in the sphere of jurisdiction 7. A Lost books must set up treatment basis of natural reduction ratio 8. The Interference factors of delivery lending library are lacks of human power, lost books and negative attitute of user in order 9. The Effects of using a delivery lending library are a positive attitute and specialty of top management, the optimum of budget and the effect of deposit system 10. Natural reduction ratio of lost books appropriates 0.5-0.6% of total loaned books

This study analyzes trends in research topics and related terms in the field of library science in North Korea. To this end, subject fields in library and information science (LIS) in South Korea, which corresponds to that of the North, were divided into seven subject categories and 25 detailed subject areas. In addition, 136 research articles published in two North Korean journals were reclassified and analyzed according to South Korea's detailed subject areas. The detailed topic area in the field of LIS is based on the criteria for posting papers of three major academic journals in the field of LIS in South Korea. The two academic journals in North Korea that were the subject of this study were "Kim Il-Seong University Journal (Language Literature)" (2008-2018) and "Reference Materials for Librarians" (2016-2017). This study not only informs South Korean researchers the trends of interest in North Korea's recent library and library science, but can also be the starting point for academic exchanges between researchers in South and North Korean libraries and related fields in the future.
