Today, the importance of test and evaluation of defense systems is increasing day by day. In performing efficient defense systems test works, process improvement based on quantitative management is essential. The purpose of this paper is to present the results of process improvement for the defense systems test works of the test organization based on quantitative management activities. As a methodology to confirm process improvement performance, the 'MPM(Managing Performance and Measurement)' practice area of the CMMI model was applied. The quantitative management model for defense systems test works was developed so that it could be practically applied not only to the entire test organization but also to the organization at the department level that actually performs the test work. Finally, the application cases of the quantitative management model for defense system test works and the results of process improvement were described.

As indoor air quality directly affects health and comforts of the residents, researchers from different countries have continued to explore criteria by which indoor air quality can be indicated in a scientific and quantitative manner over the past several decades. However, there are many possibilities that can deteriorate indoor air quality. Due to the uncertainty of influence factors, it is quite difficult to develop a correct evaluation model and quantitative method. Furthermore, the effects from the indoor air pollutants have different levels, leading to the difficulties to apply the regular standard. This study aims to propose evaluation criteria by using the FD-AHP analysis. Obtained findings will be beneficial to construct apartment buildings, commercial buildings and others health performance evaluation framework.

Even though B2B EC is becoming popular, there have been not so much studies about performance evaluation methodology for B2B systems. In this paper, after analyzing buyer-carts systematically focusing on the buyer's interactional efforts on the typical buying processes of each buyer-cart, we propose a quantitative performance evaluation model. For this, we categorize buyer-carts in B2B EC as s-cart, i-cart, and b-cart depending upon its residing sites: seller, intermediary, and buyer sites. And after proposing the desired features of buyer-carts in B2B EC as identification, collection, trashing, ordering, payment, tracking, recording, purchasing decision support, and transmission of records to e-procurement systems, we derive a performance evaluation model by calculating detail sub-processes from the desired features' viewpoints. By setting variables from a survey on the actual condition of using buyer-carts in companies in Korea, we try to evaluate the performance of buyer-carts in B2B EC. In this paper, we suggest a new methodology of performance evaluation for B2B systems, and show that the b-cart platform is more efficient than other buyer-carts especially in B2B EC.

Variety of companies which carry out R&D projects supported by government are proposing quantitative evaluation index business plans. However, Many companies have difficulties in aspects of selecting quantitative evaluation index and in some cases they have troubles to get results from selecting unsuitable evaluation index. First of all, both methods of gathering the data to be analyzed and the products which are tested by the accredited testing institutes classifying by industrial sectors are classified as the quantitative evaluation index selected by the company according to the eight quality characteristics of ISO/IEC 25023 Standard. Secondly, based on the results of the quantitative evaluation indexes classified into eight quality characteristics of the ISO/IEC 25023 standard, the tendency of the quality characteristics of the quantitative evaluation indexes selected mainly by the companies will be understandable. It is hopefully expected that this research will be helpful to select a quantitative evaluation index to evaluate the quality of software products.

Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

In this paper, we suggest a quantitative management scheme to accomplish effective weapon systems test and evaluation service(T&E). The Capability Maturity Model Integration(CMMI) process model has been introduced and applied for that purpose by the 8th directorate, Agency for Defense Development(ADD). Although a CMMI process model was developed focusing on the software development, systematic approaching scheme in the CMMI process model can be utilized for the quantitative management implementation of a weapon systems T&E service. To manage a T&E service quantitatively, at first, organizational performance objectives and sub processes are established, and then each performance indicators and performance base lines are followed.

This study aims to propose the ways to improve the research performance evaluation to support the establishment of a sound research culture. For the study, we analyzed the cases of domestic and foreign research performance evaluation, and a survey and an interview were conducted for faculty and research performance evaluation officials, respectively. In the study, the direction of establishing the principle of research performance evaluation, the method of categorizing the type of research performance, the method and procedure of research performance evaluation, and necessary documents were proposed. First, eight principles were suggested to be considered in evaluating research achievements to ensure the validity, reliability, and transparency of the evaluation while supplementing the limitations of quantitative evaluation. Second, the main types of research achievements were categorized into journal articles, books, and presentations at academic conferences. Third, as a research achievement evaluation method, a hybrid evaluation using quantitative and qualitative and multiple measurement indicators was proposed. Fourth, a total of 11 steps (required 7 steps) were presented as a procedure for research achievement evaluation. Fifth, publications, evaluation documents, and committee chair's reports were proposed as major documents for research achievement evaluation. The research achievement evaluation improvement plan presented in this study should be flexibly applied in consideration of the characteristics of the academic and research fields and universities.

The strategy for the management of earthquakes is shifting from post recovery to prevention; therefore, seismic performance management requires quantitative predictions of damage and the establishment of strategies for initial responses to earthquakes. Currently, seismic performance evaluation for seismic management in Korea consists of two stages: preliminary evaluation and detailed evaluation. Also, the priority of seismic performance management is determined in accordance with the preliminary evaluation. As a deterministic method, preliminary evaluation quantifies the physical condition and socio-economic importance of a facility by various predetermined indices, and the priority is decided by the relative value of the indices; however, with the deterministic method it is difficult to consider any uncertainty related to the return-year, epicenter, and propagation of seismic energy. Also this method cannot support tasks such as quantitative socio-economic damage and the provision of data for initial responses to earthquakes. Moreover, indirect damage is often greater than direct damage; therefore, a method to quantify damage is needed to enhance accuracy. In this paper, a Seismic Risk Assessment is used to quantify the cost of damage of road facilities in Pohang city and to support decision making.

Recently, the entertainment programs with vocal skills assessment through the broadcasting and cable broadcasting have become very popular. But, in spite of higher popularity, present performance evaluation methods including musical sympathy of the pop singers and plain performers in broadcastings are absolutely dependent on the subjective feelings of audience assessors who evaluate the musical sympathy in these programs. For solving this problem, quantitative methods instead of subjective methods in the entertainment industries for evaluating pop singer's performance and musical sympathy are taken as important issues and social demands. For this, in this paper, we propose a visual and quantitative evaluation method by applying ICT technologies that can be evaluated in all areas of musical sympathy as well as a singer's assessment.
