Purpose: The purpose of the study was to examine mission statements and their elements and to investigate correlations between mission statements and organizational performance. Methods: The current research was a descriptive study based on the examination of mission statements of 353 hospitals that posted mission statements on their webpage and 92 hospitals that made their income statements public. Results: The most common mission element was 'identification of principal services', which accounted for 92.6%. Mission statements of hospitals included the average of 4.82 mission elements out of 9, and the objective of medical quality improvement was 0.81 among 6 objectives of IOM (Institute of Medicine). Net profit of hospitals with mission statements that have above average number of mission elements were significantly higher (t=2.71, p=.008) than those of other hospitals. Net profit was significantly correlated with mission statements (r=.26, p<.001), and mission elements (r=.29, p<.001). Conclusion: The results of the study empirically reveal that mission statements in the hospital affect organizational performance. That is, better organizational performance is shown for hospitals with better, more diversified, and more firmly stated mission statements which include identification of target customers, identification of principal services, contribution to society as a non-profit organization, and concern for employees.

A general purpose aircraft mission performance analysis program has been developed. The program can be used in design mode or in analysis mode. Fuel weight for a given mission profile can be estimated when the design mode is chosen, while mission time or mission range for a given fuel can be estimated when the analysis mode is chosen. The mission analysis program is written with JAVA and includes GUI(Graphic User Interface) for users' conveniences. With a proper combination of databases for propulsion, aerodynamics and weight, the program can be configured to compute the performance of any type of aircraft. The program is validated by comparing its results with the results of a well known performance analysis program by ADD(Agency for Defense Development).

In this report, a specialization plan for wearable robots by mission profile was investigated and analyzed to derive an application plan. The final goal of this study was to derive the operating requirements of wearable robots according to specialized plans, and to conduct a specialized study on wearable robots by mission profile through investigation/analysis of specialized plans for each mission profile. In the study, 1) Research on technology trends related to military wearable robots such as patents and papers, 2) Research/analysis of mission profiles to characterize wearable robots, 3) Analysis of wearable robot specialization plans according to mission profiles, and 4) Requirements for wearable robot operation were derived. In the first time of the study, a survey on technology trends related to wearable robots for soldiers such as patents and papers was completed, and a military consultative body was conducted to derive measures to characterize wearable robots. In addition, a survey was conducted on mission profiles, and the second time study derived Key Performance Parameters (KPP) for operational performance, core performance, and system performance based on scenarios by mission profile. However, it is revealed that the KPP derived from the research results was not covered in this paper because it was judged that more in-depth research was needed prior to disclosure. In order to prepare for future battlefield situations and increase the usability of wearable robots, this study was conducted to characterize wearable robots by considering the characteristics of soldiers' equipment according to mission profiles and to characterize wearable robots by mission profile.

본 연구에서는 협업기반의 임무 수행 시 유·무인전투기 각각의 역할을 도출하고 복합 운용방안을 제시하기 위한 임무 적합도 평가 방법론을 제시하였다. 유·무인전투기 복합운용을 위한 대표 임무로 SEAD 임무를 선정하고 기체 성능, 장비성능 그리고 자율성 수준을 고려한 성능평가표를 작성하여 유인전투기와 무인전투기의 성능을 비교하였다. SEAD의 세부 임무절차를 구분하여 성능평가표의 항목과 결합된 임무적합도 평가지표를 설계하고, 전문가 설문을 통해 임무적합도를 평가하였다. 평가결과를 통해 세부 임무의 위험성과 중요도에 따라 무인기와 유인기의 적정 역할을 설정할 수 있었고, 이를 바탕으로 조종사의 임무부담을 줄이도록 임무, 통제권, 유·무인전투기의 임무 및 기동을 반영한 시간 기반의 임무계획을 수립할 수 있었다.

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.

모자이크 전장 환경에서는 다수의 무인기가 동적 상황에 따라 자율적으로 임무를 할당하고 이를 수행할 수 있어야 하므로, 임무 자율화 시스템이 무인기에 반드시 탑재되어야 한다. UxAS (unmanned x-systems autonomy service)는 미 공군 연구소에서 개발한 무인 플랫폼에 탑재 가능한 임무 자율화 시스템으로, 다양한 모듈 형태의 서비스로 구성되어 기능 확장이 용이한 구조를 가지고 있다. 이러한 UxAS에 기반한 임무 할당 및 경로 재계획을 수행하는 임무 자율화 소프트웨어를 개발하고, 해당 소프트웨어의 성능을 검증하고 성능 평가 지표에 따라 개발한 소프트웨어를 평가하는 기법에 대해 본 논문을 통해 제시하였다.

Functional analysis of air transport mission is conducted to establish the performance requirements of the commercial transport designs. The analysis process begins by making a top-down analysis to the aircraft system level mission functions. Correctly interpreting the top-level performance requirements is the first step in designing and building an aircraft system. Each function and sub-function is allocated and examined to the aircraft level and flight operations phase to optimize the system performance and design requirements, such that these lower-level requirements can be traced back to the top-level requirements they are designed to fulfill. Special attention is given to making sure all interfaces, both internal and external, are addressed. The results are also in good resources of functional hazard assessment involved in certification processes.

In M&S, radar model is a software module to identify position data of simulation objects. In this paper, we propose a radar performance model for simulations of air defenses. The previous radar simulations are complicated and difficult to model and implement since radar systems in real world themselves require a lot of considerations and computation time. Moreover, the previous radar simulations completely depended on radar equations in academic fields; therefore, there are differences between data from radar equations and data from real world in mission level analyses. In order to solve these problems, we firstly define functionality of radar systems for air defense. Then, we design and implement the radar performance model that is a simple model and deals with being independent from the radar equations in engineering levels of M&S. With our radar performance model, we focus on analyses of missions in our missile model and being operated in measured data in real world in order to make sure of reliability of our mission analysis as much as it is possible. In this paper, we have conducted case studies, and we identified the practicality of our radar performance model.

The naval unmanned surface vehicle (USV) conducts the surveillance operations, based on the mission plan set by the user. For setting the mission planning, the user needs to analyze the suitability of the operation for the mission planning. In this paper, we proposed a simulation program that estimates the probability of detecting targets of the mission planning in the analysis. In the simulation analysis, we design the USV's maneuvering characteristics, radar detection operational performance equipped on the USV, and targets infiltrating into surveillance area in the simulation experiment scenario. Based on the simulation results, we evaluated the mission planning suitability and find a mission planning solution recursively.

Since its launching on 21 December 1999, the Korea Multi-Purpose Satellite-I (KOMPSAT-I) has been successfully operated by the Mission Control Element (MCE), which was developed by the ETRI. Most of the major functions of the MCE have been successfully demonstrated and verified during the three years of the mission life of the satellite. This paper presents the operational performances of the various functions in MAPS. We show the performance and analysis of orbit determinations using ground-based tracking data and GPS navigation solutions. We present four instances of the orbit maneuvers that guided the spacecraft form injection orbit into the nominal on-orbit. We include the ground-based attitude determination using telemetry data and the attitude maneuvers for imaging mission. The event prediction, mission scheduling, and command planning functions in MAPS subsequently generate the spacecraft mission operations and command plan. The fuel accounting and the realtime ground track display also support the spacecraft mission operations.
