  • DOS 환경하에서 개발된 기존의 대부분의 응용프로그램들은 ASCII 형식의 파일을 직접 읽고 씀으로써 외부 세계와 정보를 교환한다. 수많은 단위 모듈로 이루어지는 종합적인 패키지는 모듈 각자의 입출력뿐아니라 모듈 사이의 빈번한 자료교환을 수행하여야 하므로, 모듈의 수가 증가할수록 ASCII 파일을 통한 입출력은 비효율적이고 정확성도 결여된다. 본 논문에서는 용용프로그램이 필요로 하는 모든 정보를 데이터베이스에 저장하고, 패키지의 각 모듈이 데이터베이스와 직접 정보를 교환할 수 있는 인터페이스를 설계하고 이를 실제 구현하는 과정을 보이고 있다. 개발된 인터페이스를 기존의 프로펠러 설계-해석 시스템에 적용하여 데이터베이스와의 정보교류가 원활히 수행되고 있음을 보였다. 이상을 Unix 환경하의 워크스테이션이 아닌 Windows95 환경하의 개인용/휴대용 컴퓨터에서 구현함으로써 프로펠러의 설계-해석을 시간적 공간적 제약없이 수행할 수 있음을 보였다.

  • Purpose - This paper empirically explores the RCA of electrical equipment trade between China and Korea from the perspective of gross trade and value-added trade. The goal of this paper is to scan the electrical equipment's RCA, the decomposition of gross exports, and the impacts of an exerted shock. Design/methodology - We applied the domestic value-added method in measuring the RCA, which could be more accurate than traditional RCA since it excludes foreign value-added. Based on the research purpose, this paper follows the framework of Koopman, Wang, and Wei (2014)-as extended by Wang, Wei, and Zhu (2018). It extracts the data from the 2019 Multi-regional Input-Output (MRIO) databases compiled by the Asian Development Bank in January 2021. Findings - After rigorous examination, the main findings are as follows: First, the electrical equipment sector maintains a consistent comparative advantage in either assessing method. Second, China exports more gross goods of electrical equipment to the world than South Korea does, but there is a trade deficit with Korea. Third, South Korea and P.R. China are the most significant bilateral partners of foreign value-added sourcing. Finally, it is surprising that there is a shock on electrical equipment; the partner's service, as well as manufacturing sectors, would be affected. Originality/value - This paper explores the revealed comparative advantage between Korea and China from traditional gross export and value-added perspectives. Second, we apply the information from the 2019 MRIO database compiled by the Asian Development Bank in January 2021, reflecting the current situation. Third, this paper analyzes the electrical equipment and the impacts on other parties' sectors. Finally, we carry out the subjects that deserve to be investigated in the future.

  • This study aims to assess MEE(management effectiveness evaluations) on PAs(protected areas) for forest genetic resources which play an important role in biodiversity conservation, and then to suggest better ways to manage PAs for forest genetic resources. This study applies same indicators of the MEE on PAs as the ones described in the prior study(Ryu et al. 2011). The indicators applied are composed of five elements, thirty-two indicators which all would be grouped into one element by each traits. Overall indicators belonging to the element of output and outcome are comparatively low. Especially the ones related to the change of biodiversity, degree of ecosystem health, variation of civil complaint and visitor satisfaction are ranked mostly low. The element of input shows the low rank on the number of staff and budget. The score of indicators related to the identification of the threats of PAs and local communities' supports turn out to be low in the element of Context. The element of process, however, has scored low on Staff management, Education/Awareness programs and Governance, while the law enforcement, management regulation and capacity to prevent forest disasters have made relatively high score. Meanwhile, all indicators in the element of planning have scored relatively high as compared to the indicators belonged to other elements. This study suggests to strengthen a few constructive proposals, such as facilitating efficient management framework for PAs, developing local community cooperation program, establishing survey, research and monitoring system, and registering PAs to the WDPA(World Database on Protected Areas) according to the IUCN categories.
