본 연구의 목적은 사회적기업의 미션 분석을 통해 사회적기업이 추구하는 사회적 목적을 탐색하여 사회적 문제에 대한 사회적기업의 인식을 파악하고, 이를 바탕으로 한국 사회적경제의 시대적 사명에 대해 재고하는 것이다. 이를 위해 사회적기업 자율공시자료를 수집하여 LDA 토픽모델링과 사회네트워크분석 방법을 사용하여 미션 토픽 7개를 추출하고 핵심 키워드를 중심으로 네트워크를 도출하였다. 분석결과, 사회적기업의 사회적 목적은 크게 세 가지로 '사회적 기업이 달성하고자 하는 사회적 목적', '목적을 달성하기 위한 활동 내용', '목적을 달성하기 위한 운영 방법'으로 나타났다. 본 연구는 사회적기업의 미션 분석을 통해 사회적기업의 경제적 가치 실현뿐만 아니라 사회적경제 관점에서 사회적 목적 수립 및 실천의 중요성을 강조하였다는 것에 의의가 있다.

KAISTSAT-4 is to be launched in August 2003 into an orbit at 800 km altitude with the intended mission shared between astrophysics and space physics. The primary objective of its astrophysics mission is to provide spectral sky survey data of hot Galactic plasmas in the far-ultraviolet wavelength range. Far-Ultraviolet Imaging Spectrograph (FIMS) is sensitive to emission line fluxes in 900 - 1175 $\AA$ and 1335 - 1750 $\AA$. (omitted)

다기능 선박조종시뮬레이터(Full-mission Shiphandling Simulator)를 이용한 사고분석 방법은 먼저 사고관련 정보기록을 수집하여 이에 맞는 항만/해역의 데이터베이스를 만들고 이를 바탕으로 사고 선박의 제원, 사진 및 기타정보를 토대로 일반적인 변수 값 기관 특성정보, Hydrodynamic 특성 변경과 선박의 외형에 따라 선박의 데이터베이스를 만들고, 시험운항을 통한 수치를 보정한다. 그리고 이 데이터베이스를 기초로 하여 시뮬레이션 시나리오를 만들어서 사고 당시를 재연하면서 그때, 그때의 상황의 자료를 수집하여 분석하게 된다.

Multiple cohorts (e.g., current students and graduates) were formed to collect information on the entire educational process from admission to graduation regarding students' educational performances at Kosin University College of Medicine. Data that had already been collected and analyzed by different committees for different purposes were grouped into a more systematic and comprehensive system called the cohort system, enabling the necessary data to be collected promptly and analyzed in accordance with the purpose of providing meaningful information in each area of the educational process. Therefore, comprehensive cohort data that can be used for mission statement revision, curriculum development and improvement, student counseling, and student selection were established and utilized. The cohort data were collected from performance evaluation indicators including self-evaluation surveys, evaluation tools for learning outcomes, academic achievement, results of the Korean Medical Licensing Examination, and career placement. Based on the results obtained by analyzing cohort data, a comprehensive cohort report has been published. The data analyzed through the cohort were reported to each committee and used in various ways. Currently, however, only some data have been analyzed and used. In the future, after complete data collection, the cohort data can be used as meaningful basic data for achieving the institution's mission and educational goals, developing and improving the curriculum, counseling students, and selecting students through the analysis of learning performance data from student admission to graduation and after graduation.

The STEP Cube Lab (Cube Laboratory for Space Technology Experimental Projects) is a 1U cube satellite developed by the Space Technology Synthesis Laboratory of Chosun University to be launched in 2015. Its mission objective is twofold: to determine which of the fundamental space technologies researched at domestic universities, will be potential candidates for use in future space missions and to verify the effectiveness of the technologies by investigating mission data obtained from on-orbit operation of the cube satellite. In this paper, a structural design concept based on the 1U standard to achieve the mission objective is introduced. The validity of the design has been demonstrated by quasi-static analysis and modal analysis. In addition, a non-explosive separation device triggered by burn wire heating, which is one of the main mission payloads is introduced.

In this paper we carried out a design study for an unmanned Mars missionsuitable for Republic of Korea. The mission will use a KSLV series launch system,which is to place a one tonne payload into the LEO. We calculated the velocityincrements(AV) required for departure from Earth and insertion into the orbitaround Mars based on the mission opportunity data provided by NASA. Two typesof Mars modules - entry type and orbiter type - were considered in this studyWe calculated the mass of TPS(therma1 protection system) for the entry tvpe Marsmodule based on the heat transfer rate and heat load from the Mars atmosphere tothe surface of the TPS. The heat transfer rate and heat load were obtained throughan entry trajectory calculation. For the orbiter type Mars module, we calcuIated themass breakdown of the additional spacecraft which is to insert the Mars moduleinto the orbit around Mars. Other mass items were determined by proportioningfrom the existing Mars modules. This paper finally proposes the payload capacitiesfor each types of Mars modules.

일반적으로 무인항공기는 비행 전에 계획된 비행항로나 운용자의 실시간 통제에 따라 임무를 수행한다. 성공적으로 임무를 완수하려면 무인항공기와 지상통신장비 간의 통신 가시선 분석 등이 필수적으로 요구된다. 본 논문은 무인항공기의 안전한 비행을 위해 지상통제장비가 임무계획 단계와 임무통제 단계에서 수행하는 여러 가지 분석 기법들을 제안한다. 제안된 기법들은 대부분의 무인항공기 체계에 적용될 수 있다.

The microwave instruments are used many areas of the space remote sensing and space science applications. The imaging radar of synthetic aperture radar (SAR) is well known microwave radar sensor for earth surface and ocean research. Unlike radar, microwave radiometer is passive instrument and it measures the emission energy of target, i.e. brightness temperature BT, from earth surface and atmosphere. From measured BT, the geophysical data like cloud liquid water, water vapor, sea surface temperature, surface permittivity can be retrieved. In this paper, the radiometer characteristics, system configuration and principle of BT measurement are described. Also the radiometer instruments TRMM, GPM, SMOS for earth climate, and ocean salinity research are introduce. As first korean microwave payload on STSAT-2, the DREAM (Dual-channels Radiometer for Earth and Atmosphere Monitoring) is described the mission, system configuration and operation plan for life time of two years. The main issues of DREAM unlike other spaceborne radiometers, will be addressed. The calibration is the one of main issues of DREAM mission and how it contribute on the space borne radiometer. In conclusion, the radiometer instrument to space science application will be considered.
