It is important to predict and measure the combat effectiveness (CE) of weapons system in battlefield for acquiring efficient weapon system. Moreover, quantitative calculation of weapon effectiveness under complicated and uncertain battlefield environment is also difficult based on the future network centric warfare. Many papers used the term of combat effectiveness and tried to study a lot of related issues about it. However, there is no paper dealing with the classification of study issue about CE and what will happen in this study field. In this paper, we proposed how to classify the study issue about CE and forecast future direction of this study field. Conceptually, CE is nothing but the assessment results to measure the ability of a military weapon system to accomplish its objective. We believe that it is an appropriate time to review the literature extensively on CE analysis because the research interests and the papers of CE are rapidly growing in these days. This paper reviewed many CE analysis papers, classified them according to their research content and the research methodology applied. Additionally, a comprehensive list of future research areas is also given.

This study intended to test the structure of the latent factor of an effectiveness scale and the stability of invariance across groups of students' classifications (gender and levels of education). In the large, non-clinical sample (850), students completed the effectiveness scale. The (CFA) confirmatory factor analysis was used to investigate the factor-structure of the measure, and multiple-group confirmatory factor analysis (MGCFA) model was used to test the stability of invariance across groups of students' classifications. The findings of the CFA indicated support for the original four-factor model. Additional analyses of the MGCFA method support the measurement (configural, metric and strong) invariant and practical invariant components of this model. There was an invariant across gender. There was partially invariant across groups of levels of education. The scale exists in groups of levels of education assess the same concepts of, excluding Items 15 and 10. Given that this study is the first investigation for the structure of the effectiveness scale.

The main purpose of the research is to examine impact of organizational justice and perceived organizational support on effectiveness of crime control in police organizations. This research employs a survey questionnaire to measure organizational justice, perceived organizational support, and effectiveness of crime control. The number of subject of the study is 285 police officers working in Daegu metropolitan city and some cities of Gyeongsangbuk-do province. The study employs regression analysis to analyze the effect of organizational justice and perceived organizational support on police performance. As the result of analysis, the effect of organizational justice on effectiveness of crime control is statistically significant at the level 0.01, perceived organizational support at the level 0.05. The key finding of this study is that in the performance-based management system, the reciprocal relationships between managers and individual officers with organizational justice and perceived organizational support play an important role in building a sustainable growth system in the police.

According to Korea Standard Association (KSA-0013) storage facilities are so broadly defined that one cannot easily understand the area and contents of storage facilities. Generally speaking warehouse represents storage facilities which links two nodes in various logistics activities, and storage facilities should contain other facilities like mechanization equipment, automation equipment, information equipment, etc. This study is to show the direction of the evaluation method on the effectiveness of standardized storage facilities. The storage facilities treated in this research are not only storage facilities like warehouse but also storage supporting facilities like mechanization equipment, automation equipment, information equipment, etc. The method for evaluating the effectiveness of standardized storage facilities is to developing some measure of effectiveness (MOE) which represents the entire standardized effectiveness of storage related facilities. This study has originality in that the method for evaluation of standardized storage facilities has not been developed up to now.

In this study, a tracer gas technique was used to measure ventilation effectiveness in a thermal environmental chamber simulating an under-floor air conditioning system. A tracer gas of $SF_6$ was injected in a supply duct using step-up and step-down methods. Local mean ages and room mean ages were calculated from the measured concentrations under isothermal and cooling conditions with and without diffusers. Ventilation effectiveness is found to be higher in cooling ventilation operations than in isothermal operations. Results also show that ventilation effectiveness is not significantly affected by a diffuser.

The control effectiveness and disturbance suppressibility are mainly governed by a left eigenstructure of a system. In this paper, a control algorithm which uses an output feedback eigenstructure assignment scheme is proposed in order that a desired closed-loop system has the specified degree of controllability and/or degree of disturbance suppressibility. To do this, a modal and a gross disturbance suppressibility measures are proposed. A modified version of Hamdan and Nayfeh's modal controllability measure is also presented. The validity and usefulness of the proposed measures and the controller design algorithm are illustrated by designing a controller for a third-order system as an example.

Mine countermeasure missions(MCMs) may induce the loss of human and ship because of the covert of mine. In recent years, unmanned underwater vehicles(UUVs) have emerged as viable technical solution for conductimg underwater search, surveillance, and clearance operations in support of mine countermeasure missions because of her autonomy and long time endurance capability. This paper introduces a technical approach to mine countermeasure mission effectiveness analysis and presents some simulation-based analysis results for engineering of the UUV system definition which could be support analysis of alternatives for system definition and design.

Recently, there has been growing interest in the financial and economic effectiveness of service quality and customer satisfaction. It means that the final goal of customer satisfaction is the maximization with firms' financial performance, enterprise could survive through the creation of continuous financial performance. Companies are working in various ways to identify the direct relationship of service quality and customer satisfaction with financial and economic effectiveness in order to justify and validate customer satisfaction management. In this study, the influence of customer satisfaction on the financial performance is examined. Also, we have analyzed customer satisfaction by comparing financial outcome of each industry Customer satisfaction index, the key non-financial performance measure has significant association with firms' financial performance index. Moreover, high customer satisfaction has a competitive advantage, so it can be the key success factor of firm's financial performance improvement.

In this paper, the result of study on the effectiveness of anti-submarine defense plan according to the disposition of surface ships has been proposed. The surface ship carries a hull mounted sonar(HMS) as a underwater sensor and a torpedo acoustic counter measure(TACM) as a soft-kill weapon against torpedo attacks from the enemy. Nowadays these underwater systems have been combined into a integrated anti-submarine warfare combat system. And in the real anti-submarine operation environment, several surface ships cooperate for executing ASW plans. Considering these ASW systems and the ASW environment, the models of underwater systems mounted on an surface ship and the a general model of anti-submarine defense plan are proposed. And we designed a scenario for conducting simulations to evaluate the ASW plan according to the variation of the range and the relative angle between surface ships and a capital ship. The simulation results show the effectiveness of ASW plan depends on the formation of surface ships and a capital ship.
