Advanced Life Support Systems (ALSS) are being studied to support human life during long-duration space missions. ALSS can be categorized into four subsystems: Crew, Biomass Production, Food Processing and Nutrition, Waste Processing and Resource Recovery. The System Studies and Modeling (SSM) team of New Jersey-NASA Specialized Center of Research and Training (NJ-NSCORT) has facilitated and conducted analyses of ALSS to address systems level issues. The underlying concept of the SSM work is to enable the effective utilization of information to aid in planning, analysis, design, management, and operation of ALSS and their components. Analytical tools and computer models for ALSS analyses have been developed and implemented for value-added information processing. The results of analyses have been delivered through the Internet for effective communication within the advanced life support (ALS) community. Several modeling paradigms have been explored by developing tools for use in systems analysis. They include object-oriented approach for top-level models, procedural approach for process-level models, and application of commercially available modeling tools such as MATLAB$\^$(R)//Simulink$\^$(R)/. Every paradigm has its particular applicability for the purpose of modeling work. An overview is presented of the systems studies and modeling work conducted by the NJ-NSCORT SSM team in its efforts to provide systems analysis capabilities to the ALS community. The experience gained and the analytical tools developed from this work can be extended to solving problems encountered in general agriculture.

본 연구에서는 하부구조적 결함을 갖는 전력계통의 정태 안전성 평가를 고려한 무효전력 제어 문제를 해결하기 위하여 A-team(Asynchronous team) 이론을 이용한 접근법을 제시한다. QVC는 무효전력 발전량, 전압치, 선로조류 및 다른 무효전력장치에 대한 제약조건하에서 최적의 전압을 유지하는 문제로써, 해의 정확도를 크게 해치지 않는 범위내에서 혼합정수계획법(MILP) 문제로 수식화 하였다. 안전성 평가는 계통의 모니터링을 통하여 얻어진 현재의 자료를 평가하여 상대적 강인성을 추정하는 것으로 교류 전력조류법에 기반을 둔 결정론적인 방법에 의해 계통안전성, 특히 전압안전성을 평가하였으며, 이진치 대신에 다수의 이산치를 제공하는 안전성 계량을 사용하였다. 계통의 효율적 운전을 목적으로 위의 두 문제를 통합하여 풀 수 있도록 A-team으로 명명된 새로운 조직기법을 도입하였다. A-team은 자치적(autonomous)이고, 병렬적으로(in parallel) 동작하고, 비동기적으로(asynchronously) 정보교환을 하는 agent들을 위 한 일종의 조직법으로 다수의 프로그램 (computer-based multi agent)을 이 용한 운용시스템의 구성에 적합한 방법으로 알려져 있다. 이 A-team을 이용한 방법은 실계통에 적용하기 위한 초기단계에 머무르고 있으나 대형계통의 여러 복잡한 문제를 해결할 수 있는 가능성을 갖고 있다.

Background: The resource-based relative value scale has been applied to Korean medicine services as part of the National Health Insurance, yet the proper scoring method for physician's work needs to be developed. Objectives: To measure physician's work for Korean medicine services using Analytical Hierarchy Process(AHP) and to compare results abstracted by AHP with those by Magnitude Estimation method. Methods: We developed the AHP questionnaires for Korean Medicine services and administered it to 12 Korean medicine insurance experts. Weighted scores were calculated and were converted into physician's work scores. Results: In AHP measurement, the physician's work scores for acupuncture activities, especially special acupunctures, far increased, while those for diagnosis and basic consultations decreased. Variations in the scores enlarged. Conclusions: As an alternative, AHP method can be considered for measuring the physician's work for Korean medicine services with careful management of scoring variation.

Abstract Griseofulvin has been used as an antifungal antibiotic for the treatment of mycotic diseases of humans and veterinary animals. The purpose of this work was to identify a griseofulvin-producing endophytic fungus from Abies holophylla and evaluate its in vivo antifungal activity against plant pathogenic fungi. Based on nuclear ribosomal ITS1-5.8SITS2 sequence analysis, the fungus was identified and labeled as Xylaria sp. F0010. Two antifungal substances were purified from liquid cultures of Xylaria sp. F0010, and their chemical identities were determined to be griseofulvin and dechlorogriseofulvin through mass and NMR spectral analyses. Compared to dechlorogriseofulvin, griseofulvin showed high in vivo and in vitro antifungal activity, and effectively controlled the development of rice blast (Magnaporthe grisea), rice sheath blight (Corticium sasaki), wheat leaf rust (Puccinia recondita), and barley powdery mildew (Blumeria graminis f. sp. hordei), at doses of 50 to 150 ${\mu}$g/ml, depending on the disease. This is the first report on the production of griseofulvin and dechlorogriseofulvin by Xylaria species.

팀의 규모에 관한 연구 결과 전문가들은 일반적으로 업무를 수행하는데 규모가 작은 팀이 큰 팀 보다 좋다는데 동의하고 있다. 또한, 항상 최소한의 실질적인 팀 규모를 구성하는데 목표로 하고 있다. 그러나 "작은"이 얼마를 의미하는지가 문제가 된다. 본 논문에서는 프로젝트 인도율과 인도속도와 같은 생산성 측도를 도입하여 이상적인 팀 규모를 결정하였다 300개 프로젝트를 대상으로 데이터 집합을 2개의 서브 그룹인 개발 프로젝트와 유지보수 프로젝트로 분류하였다. 실험결과 가장 성공적인 프로젝트는 최대 5명으로 수행하는 경우였으나, 본 논문은 실제 개발 된 프로젝트들을 대상으로 생산성-기반 이론을 접목시켜 이상적인 팀 규모를 판단하는 지침을 제공한다. 지침을 제공한다.

This study aims to investigate the Healthy Family Support Centers'(HFSCs) operational patterns and their programs by surveying 46 HFSC employees in order to prepare for the massive increase of the number of HFSCs nationwide. This study might contribute to not only rebuilding the HFSCs' operational strategies but suggesting visible ideas for the HFSCs' programs. Results were as followed: First, most HFSCs consisted of several teams, i.e., educational team, counseling team and cultural team. However, the number of employees in each team was different from one regional community to another. The most difficult task in the HFSCs' operation was publicity work. Citing the issue of system delivery difficulties, HFSC employees insisted that budgetary deficit was the most difficult obstacle in running the HFSCs. Second was in regards to the programs that each team was planning, performing, and evaluating for each program. The HFSCs' programs were mostly structured around family difficulties or problems that arise according to the family life cycle. Based on these study results, more unified and specialized programs for HFSCs should be developed. In order to achieve this related studies should continue to conducted.

Recently, various type of nanomaterials such as nanorod, nanowire, nanotube and their core/shell nanostructures have attracted much attention in photocatalyst due to their unique properties. Among them, Type-II core/shell heterostructures have extensively studied because it has exhibited improved electrical and optical properties against their single-component nanostructure. Such structures are expected to offer high absorption efficiency and fast charge transport due to their stepwised energetic combination and large internal surface area. Thus, it has been considered as potential candidates for high efficient photocatalytic activity. In this work, we introduce a novel chemical conversion process to synthesize Type-II ZnO/ZnSe core/shell heterostructures. A plausible conversion mechanism to ZnO/ZnSe core/shell heterostructres was proposed based on SEM, XRD, TEM and XPS analysis. The ZnO/ZnSe heterostructures exhibited excellent photocatalytic activity toward the decomposition of RhB dye compared to the ZnO nanorod arrays due to enhanced light absorption and the type-II cascade band structure.
