This study investigated contents of mission statements for Strategic Management of hospitals in Korea and Japan. For the study, 44 tertiary care hospitals in korea, which were accredited by the Ministry of Health and Welfare, were selected. And 83 special functioning hospitals in Japan, which were approved by the Minister of Health, Labour and Welfare, were included. Both quantitative and qualitative analyses were conducted by classifying 5 components of the mission statement; market, service, philosophy, image, contribution. Findings from this study are as follow. First, hospitals in Korea emphasized image(93.2%) and philosophy(81.8%) components in their mission statements, whereas hospitals in Japan highlighted components of service(89.2%) and market(72.3%). In detail, mission statements of Korean tertiary care hospitals describe the components of hospital's image (93.2%), philosophy(81.8%), contribution(56.8%), market(22.7%) and service (18.2%) in order. On the other hand, mission statements of Japanese special functioning hospitals describe hospital's service(89.2%), market(72.3%), contribution(61.4%), image (49.4%) and philosophy(34.9%), respectively. Second, as results of Content analysis, there were some differences in mission statements of hospitals between two countries, and it is mainly from the divergences of standards for recognition of medical institutions, environmental factors, and different ways of mission statement description. For strategic hospital management, carrying out innovative restructuring organization or promoting of research and training for medical development is considered as a desirable approach. However, clear description of mission statement is more important and it is required for effective control and managing organization. And then the mission should be communicated within an organization so all internal members understand it and put their efforts to achieve the mission of organization. In conclusion, it is recommended that a leader and senior managers should re-evaluate its mission statement whether it reflects characteristics of an organization. In addition, a mission statement should be created or improved based on critical decision, as well as it should be clearly shared within an organization in order to become a future oriented organizations.

전투기의 개념설계 과정에서는 기준형상 도출을 위해 비교분석연구가 반복된다. 반복적인 비교분석연구가 자동화되면 효율적으로 기준형상을 도출할 수 있다. 본 연구에서는 비교분석연구의 자동화를 위한 성능해석 프로그램을 개발했다. 프로그램은 형상생성모듈과 중량예측모듈, 임무성능 해석모듈로 구성된다. 형상생성모듈을 사용하여 3D CAD 모델 생성이 가능하며 중량예측모듈에서는 경험식을 사용하여 중량을 예측한다. 임의의 임무형상에 대한 임무성능 해석이 가능하며 최적화 기법을 사용하여 최적 임무성능 계산이 가능하다. 개발된 프로그램의 검증을 진행하여 개념설계 단계에 적용 가능함을 확인했다.

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.

This paper describes link analysis on the processed data, HRIT (High Rate Information Transmission) and LRIT (Low Rate Information Transmission), for the preliminary design of interface between COMS (Communication, Ocean and Meteorological Satellite) and ground station. At the MODAC (MeteorologicaVOcean Data Application Center), the processed data are transmitted to user station via COMS with normalization and calibration by pre-processing of MI (Meteorological Imager) data. Due to consider satellite as radio relay, overall analysis containing uplink and downlink is needed. Specific link parameters can be obtained with using the outcomes of SRR (System Requirement Review) which was held on 13-14 June 2005, in Toulouse. From the relation between overall link margin and output power of HPA (High Power Amplifier) of MODAC, it is shown that even though the minimum power related with COMS receiving power range is transmitted at MODAC, the obtained link margin of HRIT could be above 3 dB at user station which antenna elevation angle is 10 degree.

The current study designs the mission orbit of the lunar CubeSat spacecraft to measure the lunar local magnetic anomaly. To perform this mission, the CubeSat will impact the lunar surface over the Reiner Gamma swirl on the Moon. Orbit analyses are conducted comprising ${\Delta}V$ and error propagation analysis for the CubeSat mission orbit. First, three possible orbit scenarios are presented in terms of the CubeSat's impacting trajectories. For each scenario, it is important to achieve mission objectives with a minimum ${\Delta}V$ since the CubeSat is limited in size and cost. Therefore, the ${\Delta}V$ needed for the CubeSat to maneuver from the initial orbit toward the impacting trajectory is analyzed for each orbit scenario. In addition, error propagation analysis is performed for each scenario to evaluate how initial errors, such as position error, velocity error, and maneuver error, that occur when the CubeSat is separated from the lunar orbiter, eventually affect the final impact position. As a result, the current study adopts a CubeSat release from the circular orbit at 100 km altitude and an impact slope of $15^{\circ}$, among the possible impacting scenarios. For this scenario, the required ${\Delta}V$ is calculated as the result of the ${\Delta}V$ analysis. It can be used to practically make an estimate of this specific mission's fuel budget. In addition, the current study suggests error constraints for ${\Delta}V$ for the mission.

In this paper, the preliminary transfer orbit analysis results for the COMS mission were presented. As the first step of transfer orbit analysis, the preliminary analyses of LAE burn strategy, geometrical visibility, and launch window were performed. For the analysis process, all launcher nominates were divided into three groups according to the declination of LAE thrust angle. So, the three launch cases were assigned as the representative launcher of each group, respectively. They are Ariane-5, Atlas summer and winter launch cases. And all analyses were performed at the representative launcher of each group. One nominal and three back-up plans were considered for the establishment of LAE burn strategy. And for geometrical visibility analysis, four TT&C ground stations were considered. Finally, the preliminary launch window analysis was performed about the duration of one year from the first day of September 2008. The analysis results show that the all launch cases comply with the transfer orbit operation requirements.

A method of multiple transport-aircraft mission modeling is proposed in order to improve the efficiency of evaluating and optimizing pre-mission plans. To deal with the challenge of multiple transport-aircraft missions, the object-oriented modeling method is utilized. The elements of the mission are decomposed into objects and businesses, And the major mission objects and their important properties are summarized. A complex mission can be broken down into basic business modules such as the ground section and flight section. The business models of loading and fueling services in the ground section are described. The business model of the flight section is composed of an air route and flight profile with the flight equation and the fuel consumption model. The logical relationship of objects and business modules is introduced. The architecture of the simulation system, which includes a database, computation module, graphical user interface (GUI) module, and a result analysis module, is established. A sample case that includes two different plans is provided to verify the model's ability to achieve multi-aircraft composite mission simulation.

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.
