In this paper we introduce a new style multiparadigm language named Argos which applies a compositional approach [20] to multiparadigm programming. Argos is a superset of the Java, and its grammar has an extension point which allows other languages to be used in Argos programs. Therefore, Argos can support object-oriented programming and multiparadigm programming by enabling each method in a class to be implemented with one of the Java, C, Prolog, Python, and XML languages. Since Argos allows the existing languages to be used, it has advantages such as easiness of learning and high reusability. The Argos compiler is implemented according to the delegating compiler object (DCO) model[28,29]. The compiler partitions a program Into several parts according to the languages used in methods and delivers the parts the languages' processors which compile the parts.

The purpose of this study is to investigate the distributive property of organic pollutants in effluents of argo/industrial wastewater treatment plants in Jeonnam using simultaneous analysis method of 310 chemicals. The numerous organic pollutants were detected in four sampling sites and the major chemicals were pesticides, CH type chemicals such as polycyclic compounds, CHO type chemicals such as phthalates, and CHO(N) type chemical such as aromatic amines. Moreover, 17 kinds of endocrine disrupters which include diethylptbalate were detected in each sampling sites. TU (Toxic unit) indicated cytotoxicity of samples using XTT assay, it appeared highly at A point(27.2) and D point(24.4). Also, the results from the correlation between total concentration of pollutants and TU did not correspond to the results of chemical and biological analysis.

한국천문연구원은 우주측지용 레이저 추적 시스템 개발 사업 중 현재 이동형 시스템(ARGO-M) 1기를 개발 중에 있으며, 2009년 5월에 시스템 개념 설계 검토(SDR) 회의를 수행하였고 현재는 예비 설계 단계를 진행 중이다. ARGO-M을 구성하는 5개의 서브시스템 중 하나인 운영시스템은 레이저 관측에 필요한 각종 서브시스템을 제어하고 환경을 종합 판단 후 이를 관측에 반영하며, 실제 관측을 통해 획득한 데이터를 통합 처리 및 전송하는 역할을 담당하고 있다. 현재 본격적인 예비 설계 수행 단계에 있는 운영시스템은 우선적으로 핵심이 되는 소프트웨어의 설계를 위해 오스트리아의 Graz에 위치한 IWF(Institut fur Weltraumforschung) 소속 SLR(Satellite Laser Ranging) 관측소를 2009년도에 방문하여 운영 전반에 관련한 소프트웨어의 로직분석 작업을 수행하였다. Graz 운영시스템 중 소프트웨어관련 시스템은 크게 KHz급 반복율을 가진 레이저를 사용하여 위성까지의 거리 측정에 해당되는 실시간 시스템과 실시간 측정을 통해 저장된 관측 원시 자료를 이후 분석을 수행하는 비 실시간(Non-real time) 시스템으로 나눌 수 있다. 이 중에서 비 실시간 시스템은 원시 자료 분석을 통해 시간 및 거리 바이어스 적용, 노이즈 제거 등의 후처리 과정과 다양한 통계 분석 그리고 SLR시스템의 최종 산출물인 정규점(Normal Point) 생성 등을 수행한다. 이번 소프트웨어 분석 연구를 통해 얻어진 주요 알고리즘과 다양한 다이어그램을 포함한 결과물은 ARGO-M 운영시스템에 최적화하도록 소프트웨어 재구성 및 개발에 반영할 예정이다.

Drift data from 17 Argo profiling floats in the East Sea are used to understand the mean flow and its variability in the upper portion of the East Sea Proper Water (UESPW) (around 800 m). The flow penetrates into the Ulleung basin (UB) through two paths: an extension of the southward flowing of the North Korean Cold Water along the east coast of Korea and between Ulleung Island and Dok island. Flows at 800 m are observed in the range of from 0.2 to 4.29 cms-1 and the variability in the north of the UB is larger than that in the south of the UB. In the UB, cyclonic flows from 0.3 to 1.6 cms-1 are observed with the bottom topography. We found that the mean kinetic energy (MKE) and the mean eddy kinetic energy (EKE) are 1.3 and 2.1 cm2s-2 respectively.

Long-term, continuous, and real-time ocean monitoring has been undertaken in order to evaluate various oceanographic phenomena and processes in the East/Japan Sea. Recent technical advances combined with our concerted efforts have allowed us to establish a real-time monitoring system and to accumulate considerable knowledge on what has been taking place in water properties, current systems, and circulation in the East Sea. We have obtained information on volume transport across the Korea Strait through cable voltage measurements and continuous temperature and salinity profile data from ARGO floats placed throughout entire East Sea since 1997. These ARGO float data have been utilized to estimate deep current, inertial kinetic energy, and changes in water mass, especially in the northern East Sea. We have also developed the East Sea Real-time Ocean Buoy (ESROB) in coastal regions and made continual improvements till it has evolved into the most up-to-date and effective monitoring system as a result of remarkable technical progress in data communication systems. Atmospheric and oceanic measurements by ESROB have contributed to the recognition of coastal wind variability, current fluctuations, and internal waves near and off the eastern coast of Korea. Long-tenn current meter moorings have been in operation since 1996 between Ulleungdo and Dokdo to monitor the interbasin deep water exchanges between the Japanese and Ulleung Basins. In addition, remotely sensed satellite data could facilitate the investigation of atmospheric and oceanic surface conditions such as sea surface temperature (SST), sea surface height, near-surface winds, oceanic color, surface roughness, and so on. These satellite data revealed surface frontal structures with a fairly good spatial resolution, seasonal cycle of SST, atmospheric wind forcing, geostrophic current anomalies, and biogeochemical processes associated with physical forcing and processes. Since the East Sea has been recognized as a natural laboratory for global oceanic changes and a clue to abrupt climate change, we aim at constructing a 4-D continuous real-time monitoring system, over a decade at least, using the most advanced techniques to understand a variety of oceanic processes in the East Sea.
