  • Human resource management (HRM) deals with essentially complex human phenomena and multiple interactive relationships. Thus, the use of quantitative data to research and understand HRM is necessarily limited. Although important qualitative issues in HRM research are often central to supporting or creating a firm's competitive advantage, they are frequently neglected. Research into HRM is increasingly difficult and complicated, therefore, it is very difficult to research through strict quantitative methods. This paper's focus is to develop an effective idea for applying qualitative research approaches to HRM studies. A justification of a qualitative approach is considered as being a superior means for researching HRM issues. The underlying foundation of this paper is that new problems are confronted HRM research, therefore, qualitative research methods will be necessary. It is suggested that quantitative analysis in understanding and explaining firm's HRM is not sufficient and a qualitative may provide the indepth insight into HR researches.

  • When compared to land territorial claims, maritime claims have not attracted as much attention from the public as well as the academia. However, after the ICOW (Issue Correlates of War) data was published and was expanded to include maritime and river claims, there have been many quantitative studies that analyze maritime claims or separate different types of territorial claims to explain various mechanisms over different types of territorial claims. These quantitative studies have provided valuable explanations about the onset and the management of maritime claims. This research tries to review these quantitative research. Most studies about maritime claims, especially regarding the management of claims, analyze maritime claims based on two different levels of factors. First, from the perspective of systemic level, several studies focus on the role of international institutions and systemic level of democracy to explain the management of maritime claims. Second, at the dyadic level, many studies explain how the issue salience, past experience, the presence of resources, joint democracy, and relative power influence the occurrence of peaceful settlement attempts or conflictual behaviors over maritime claims. Based on the review of these literature, this research tries to identify several factors to explain the Dokdo issue and to encourage peaceful settlement attempts over the Dokdo issue.

  • For the development of a better product which fits to the target user population, physical workloads such as reach and visibility are evaluated using digital human simulation in the early stage of product development; however, ergonomic workload assessment mainly relies on visual observation of reach envelopes and view cones generated in a 3D graphic environment. The present study developed a quantitative assessment method of physical workload in a digital environment and applied to the evaluation of a Korean utility helicopter (KUH) cockpit design. The proposed assessment method quantified physical workloads for the target user population by applying a 3-step process and identified design features requiring improvement based on the quantified workload evaluation. The scores of physical workloads were quantified in terms of posture, reach, visibility, and clearance, and 5-point scales were defined for the evaluation measures by referring to existing studies. The postures of digital humanoids for a given task were estimated to have the minimal score of postural workload by finding all feasible postures that satisfy task constraints such as a contact between the tip of the index finger and a target point. The proposed assessment method was applied to evaluate the KUH cockpit design in the preliminary design stage and identified design features requiring improvement. The proposed assessment method can be utilized to ergonomic evaluation of product designs using digital human simulation.

  • In this paper, we introduce PMS's main function and main effect which implemented medium and large scale software development project site, and we propose importance and improvement nacessity of PMS implementation. PMS's main functions are developed based on best practices which CMMI model and PMBOK. Also, each PMS has specialized unique function according to it's target industry area or related I.T solutions which has infra dependency. The effectiveness of PMS implementation on project site is seperated two types, one is qualitative effect, the other quantitative effect. Representative qualitative effects are improvement of enterprise's image and competency. Also representative quantitative effect is reduction of project management cost as a financial effect. As far as project size is increase, PMS's needs and necessariness will be increase, so we need to improve PMS;s function according to project management's global trend and software customer's requisition.

  • Multimedia service whose use is rapidly increasing supports effective services to convert and transmit multimedia data based on network speed, noise circumstance, terminal computation, and type of contents for satisfying QoS. For supporting information protection of multimedia service, it offers middle level of singular security service or security mechanism which is based on policy of service provider, depending on present terminal computation and type of contents. It can support security mechanism for more effective multimedia service, if we study security of application layer and network layer for supporting multimedia service. In this paper, we propose Multimedia security framework reflected on quantitative analysis of the WLAN(Wireless Local Area Network) mesh network security using the utility function in the level of the sorority, violation and addictive compensation model.

  • This study was performed to develop a method for quantitative analysis obtaining the amount of calcium carbonate minerals formed when Ca salts biomimetically reacted with carbon dioxide. There were two methods compared; 1) volumetric calcimeter method that determining the amount of released carbon dioxide after calcium carbonate minerals were acidified by 4N HCl and 2) Thermogravimetry-Differential Thermal Analysis (TG-DTA) adopting differential decomposition temperature breaking-up the structural link within calcium carbonate minerals. The comparisons were made by batch experiment (i.e., biocalcification process) along with control (i.e., nominal concentration of $CaCO_3$ prepared). For the control, TG-DTA took a minor root mean square deviation (RMSD) of 1.1~5.9 mg, whereas volumetric calcimeter exposed a greater RMSD of 28.3 mg. For the biocalcification, the amount of $CaCO_3$ was more precisely obtained for TG-DTA rather than that of volumetric calcimeter. It was decided that TG-DTA was more successfully used for quantitative analysis to observe the amount of calcium carbonate minerals derived from biocalcification.
