미얀마 Indo-Burma 지역은 13,500종의 식물종이 분포하고 있는 생물다양성 핫스팟이다. 북부 산악지역에서 남부의 망그로브 지역에 이르는 다양한 특성의 생태계로 구성되어있다. 그러나, 풍부한 생물 다양성은 인간에 의해 인위적인 간섭, 개발, 모노크림 재배와 같은 지속적인 삼림 벌채로 위협 받고 있다. Dprovidedc와 Krupnick (2018년)은 123과 472종의 미얀마 약용식물을 학명, 영명, 미얀마 식물명 그리고 미얀마 현지에서 쓰이고 있는 약용식물의 활용 및 보존 상태를 종합적으로 정리했다. 이 중 약 13%가 보존 상태에 대한 평가를 받았으며 IUCN의 멸종 위기 종 목록(IUCN2017)에 등재되었다. 비록, 전국에 다양한 식물 및 생물 다양성이 분포되어 있지만, 미얀마는 여전히 지속 가능한 관리와 사용을 위한 인적자원과 시설이 부족하다. 국립수목원(KNA)은 2013년부터 미얀마 천연자원환경보전부(MINISTRY OF NATURAL RESOURCES AND ENVIRONMENTAL CONSERVATION, MONREC)와 미얀마 산림과학원(Forest Research Institute, FRI)과 함께 미얀마 보호지역 및 Saggaing 지역 내 식물 다양성 보존을 위한 공동 현장조사, 연구 및 출판 등의 협력사업을 진행하고 있다. 또한 국립수목원(KNA)는 약용으로 가치가 있는 미얀마 식물 생체를 수집, 현지외 보전 중이며 이중 65과 326종의 식물 생체를 국립수목원(KNA)에 있는 열대식물자원연구센터에 보존과 교육 목적으로 전시 중이다. 이 기증은 미얀마에서 식물생체를 국외로 반출한 첫 번째 사례이며 국립수목원(KNA)은 2008년 독일에서 열대식물을 기증받은 사례 다음으로 두 번째로 외국 정부의 공식적인 대량 식물 도입 사례이다. 도입한 식물 중 Santalum album L. 과 Amorphopallus paeoniifolius (Dennst.) Nicolson. 은 IUCN Red List of Threated Spiences (IUCN2017)에 취약(Vulnerable, VU), 관심필요(Least Concern, LC)로 분류되어 있다. 국립수목원 (KNA)는 2019년 6월 17일 개최된 "2019 아태지역 산림주간 및 28차 아태지역 산림위원회"에 참가하여 미얀마 도입식물 전시회를 개최 하였고, 국내 최초로 Amorphopallus paeoniifolius (Dennst.) Nicolson.의 Leaf Cycle을 타임랩스 촬영하여 국립수목원 웹진(10월 호) 과 YouTube에 연구성과를 홍보하고 있다. 또한 국립수목원 열대식물자원연구센터는 2,700여종의 미얀마, 라오스 등 무한한 가치를 지닌 열대식물의 수집 보전으로 기초 응용 연구기반을 구축하여 국민들에게 열대식물의 중요성과 잠재적인 자원가치를 알리는 역할을 하고 있다.

In recent years, public bicycle systems are widely spread over the world according to the development of ICT technology. Since the public bicycle systems in large cities need to secure both publicity and convenience for citizens, analysis of various their issues from introduction to operation is required. In addition, it is also necessary to prepare for various scenarios for coexistence with the PM business, which is recently in the spotlight as a last mile means and normally managed privately. This paper introduces modeling and simulation for efficient operations of public bicycle systems. In particular, the proposed method was developed in a form that can be easily used in other cities by modeling the general structure and behavior of the public bicycle system, and it was developed to facilitate modification and expansion of the future model with a component-based model configuration. This paper provides a case study of the propose method, which is the public bicycle simulation in Sejong City. The simulation results were derived by applying the data from the public bicycle system of Sejong City, and they were verified with the associated real data of Sejong City. Using the verified model, it is expected that it can be used as a tool to design and analyze various services on the public bicycle systems, which were especially suitable for Sejong City.

This study examines the policies currently announced in the "3rd Comprehensive Library Development Plan" in relation to the discovery of individuals' potential in libraries and analyzes the current status of the tasks promoted and executed by central administrative agencies and municipal and provincial libraries based on these policies. Based on the analysis results, this study presents the methods for libraries to play their role in discovering the potential of individuals in the future. According to the results of this study, due to the poor performance of libraries resulting from reduced in-person events because of library closures and the promotion of non-contact services such as humanities classes and cultural programs in response to COVID-19, it is necessary to establish systems to support emergency management and non-contact programs in response to COVID-19, as well as increase the budget for extending reading culture projects for underprivileged regions and people. In addition, it is necessary to discover quality long-term, non-contact programs, provide infrastructure for non-contact program operation, and develop guidelines. Second, it is observed that communication- and discussion-type social reading programs need to be promptly converted into and operated as online classes. Third, the study results confirm that it is necessary to prepare measures to reinforce external cooperation, such as improving the convenience of and accessibility to information use for users, conducting seminars between domestic and foreign councils, promoting one-stop data sharing systems, executing data digitalization, expanding library infrastructure in preparation for the post-COVID-19 era, and promoting public relations activities.

Korean construction companies first advanced to the international markets in 1960's and so far have brought more than 4,900 projects which account for 193 billion dollars approximately. With the large increase of national employment and income being followed by the achievement, Korea's construction industry has made an enormous contribution to the improvement of domestic economy for the last 40 years. However, recently the increased risk in international markets as well as the sharpening competition with foreign companies promising in terms of advanced technologies and low labor cost have been driving Korean construction away from the market shares. According to ENR (Engineering News Record, 1994~2003), it is revealed that 15.1% of top 225 global contractors are suffering from loss in international construction markets. This phenomenon is largely due to the highly uncertain characteristics of international projects, which are inherently exposed to various and complicated risky situations. Furthermore, especially for Korean construction companies, it is often the case that the failure in an international construction project cannot be offset by even a sufficient number of successful domestic achievements. Therefore, not only the selective screening among the nominated projects which have strong possibility of collapse but the systematic strategies for controlling potential risk factors are also considered indispensable in international construction portfolio management. The purpose of this study is to first analyze the causal relationships of the profit-influencing variables and the project success, and develop the profitability forecasting model in international construction projects.

The dynamics of suspended sediment (SS) in forested catchments vary depending upon human or natural disturbances, including land use change, forestry activity, forest fires, and landslides. Understanding the dynamics of SS originating from the potential sources within a forested catchment is crucial for establishing an effective water quality management strategy. Therefore, to suggest a systematic method for interpreting SS dynamics, we evaluated the performance and applicability of ten methods for calculating the hysteresis index based on observed hydrological data and two calculation models (Lawler's method and Lloyd's method) with five sampling intervals (50th, 25th, 10th, 5th, and 1st percentiles). Our results showed that Lloyd's method, which used a sampling interval at the 1st percentile, had the largest number of analyzable runoff events and exhibited the best performance. The results of this study can contribute to quantifying the hysteresis in the relationship between discharge and SS and provide useful information for interpreting SS dynamics.

Objectives: This study was conducted to compare the present community health practitioners(CHPs)'s operating activities with their activity in 1989. Methods: Data were obtained two hundred seventy eight CHPs by self-administered questionnaire regarding duty traits, job satisfaction, and others. Results: The number of CHPs was 255 in 1989 and 224 in 2000. Age of CHPs in 2000 was much higher than that in 1989, and married women was 64.9% in 1989 and 95.9% in 2000. Both the primary duty of CHPs in 1989 and that in 2000 was medical service, and others(maternal health, infant health, family planning, and tuberculosis management, etc) are decreased in 2000, and community health service was added to duty of CHPs in 2000. 55% of CHPs in 1989 satisfied with their job, whereas about 80% of CHPs in 2000 satisfied with their job. The CHPs perceived that their primary necessary duty among requisite duty are medical practice(57.7%), health education(31.4%), and community health service(10.9%), in contrast, unnecessary duty are family planning(68.8%), tuberculosis management(11.1%), infant health(6.3%) maternal health(5.6%). Conclusions: These results suggest that there are such alteration of job satisfaction, needs and obstacles in duty traits of CHFs. These trend of duty traits are major issues to be caught for the health service in primary health post.

During more than 20 years of practice, Civil Aviation Law has experienced three times of amendments since it was enacted in 1995. But these revisions are limited to the technical level. The problems and limitations have become increasingly prominent in its implementation. Firstly, the civil aviation law is the result of interests game among several departments and some legal issues was left behind and the regulation was very vague as a result. Secondly, the process of aviation legislation is the process that the country has undergone profound changes and social transformation. The 20 years is long enough for the society to undergo tremendous changes and 1995 version of civil aviation law does not keep pace of development of economy. There was a serious lag between reality and the law. In order to actively promote the development of the aviation industry and overcome implementation issues of the Civil Aviation Law, Civil Aviation Administration of China (CAAC) initiated modification procedure the law and published new draft of Civil Aviation Law in August 2016. The spirit of this modification is to learn and absorb new achievements of domestic and foreign legislation and the International Convention on civil aviation. Furthermore, the purpose of the revision is to provide favorable policy for the development of civil aviation industry and improve aviation safety and supervision, strengthen and protection of consumer rights and interests, to enhance the safety of civil aviation activities, and promote the development of general aviation. This revision concerned to the 78 articles which are revised or deleted and 24 articles added. The highlights of the draft include but not limited to the enhancement of security management, clarification of the main responsibility for production safety. And also it added the provisions related to the construction of effective tracking capability of public air transport enterprises and license system on the transport of dangerous goods. Compared with the existing civil aviation law, the draft has made a great improvements. But there are several deficiencies and limitations in the drafts. These problems need to be supplemented and perfected through further amendments in near future.

The Yellow sea, as described in article 123 of UNCLOS, is semi-enclosed sea surrounded by the Republic of Korea, the People's Republic of China and North Korea. In addition, the Yellow Sea is one of the 66 large marine ecosystems as it contains large amounts of marine resources. According to article 194 of UNCLOS, states should be aware of rights and duties with respect to the protection and preservation of the marine environment to be engaged with countries directly as regional entity or indirectly. Therefore, the legal blank is urgent in terms of trans-boundary environmental pollutant issues. The UNDP has conducted a project called Yellow Sea Large Marine Ecosystem (YSLME) which has reached the 2^nd phase. The project has some notable achievements, namely performing joint activities on analysis of diagnostic trans-boundary issues in collaboration with China and South Korea, developing a strategic action plan based on TDA, and establishing regional strategic action plan. However, on the other hand, the project could not reflect the full participation of North Korea as a state party. As a result, the project has a limitation on effective implementation of RSAP. Therefore, this study focuses on the suggestion of a legally-binding trilateral treaty as a blue print for the next, 3^rd phase of the project. By analyzing the best practice of the Wadden Sea Trilateral Treaty case, the study verifies the validity of legislative measures on establishing and managing a legally-binding trilateral YSLME Commission. By suggesting a three phase treaty, incorporating a joint declaration by establishing the commission, the signing of the treaty, and formulating an umbrella convention and implementation arrangement, the study expects to guarantee the consistency and sustainability of the trilateral treaty regardless of political issues pertaining to North Korea.
