  • This paper describes the development process for vibration and acoustic characteristics of a balanced armature speaker. The design parameters were chosen in consideration of the influence of the bending stiffness of balanced armature which is the form of a cantilever structure in the speaker. For study of the performance of the speaker according to the design parameters, in the first step, we analyzed the characteristics of the velocity of the diaphragm to the electrical input. Next step, acoustic characteristics were analyzed by structural-acoustic coupled analysis. And the reliability of the analysis was verified by comparing the result of analysis with test results. Finally, we proposed a design method for implementing an enhanced balanced armature speakers through analysis method.

  • Purpose: The purpose of this study was to analyze key performance indicators using a balanced scorecard in the nursing department of hospitals, and to find useful suggestions for future research. Methods: Before starting the literature search clear inclusion and exclusion criteria were determined. After that, were viewed 41 studies from the RISS, KISS, National assembly library, and NDSLDB. Data were collected on October 17, 2013. Researchers developed an analytic framework for the literature review using a balanced score card development process and construction steps of previous studies. This framework had 10 steps related to the balanced score card development process. Results: A total of 10 studies met the inclusion and exclusion criteria. We identified 234 key performance indicators for the nursing department. The average number was 6.6 in finance perspective, 8.6 in perspective, 11.9 in internal process perspective, and 6.2 in learning and growth perspective. We found that 173 indicators had been cited only once. 61 indicators were cited over twice. Further, 8 indicators employed different perspectives on different studies. Conclusion: The results of the present study summarize useful information on recent trends on key performance indicators using a balanced score card in the nursing department of hospitals. These results will help develop key performance indicators and provide directions for future research.

  • This paper defines measurement index items and weight of the index for the purpose of developing a performance measurement index that balancedly measures performance of B2B electronic commerce. The deductive research is used for the development of measurement index items and Analytic Hierarchy Process(AHP) method for the development of weight of the index. This paper has four performance measurement perspectives-finance, partners, business process and human resources, which based the existing researches of balanced performance measurement. This researchers developed eleven second level criteria and twenty-six indexes under four perspectives through the deductive method and expert interviews, weighted on the perspectives, criteria and indexes in accordance with the forms of e-marketplace-vertical and horizontal. As a result, the most important indexes are the maintenance of partners and the efficiency of operation process in the vertical e-marketplace. In the horizontal e-marketplace, the collection of partners, development and prediction processes are more important than other indexes.

  • Since the 2000s, China has been trying to develop the mid- and western regions and reduce regional disparity between the eastern region and the others by construction of the eight HSR corridors known as 4+4. The high-speed railway is known to have a positive impact on regional economic development by improving accessibility between regions. However, some studies point out that the high-speed railways could worsen regional imbalances. The purpose of this study is to examine the impact of the high-speed railway on regional economic growth and balanced development in China, using the beta-convergence model. In particular, we focused on how the effects of high-speed trains on regional economic development varied depending on the level of development. The analysis was conducted centering on the Shanghai-Chengdu line which is connecting eastern, central and western regions with different levels of development.

  • The study aims to analyze the theoretical background of the economic growth and sustainable development; systematization of scientists view on monitoring and economic and innovative evaluation, analysis and diagnosis of factors affecting these processes. Rating characteristics of the level of innovative resources development obtained based on the comparative analysis of Kazakhstan regions. Calculations were done based on official statistics during 2010 and 2015-2017. Based on obtained data there has been grading of the country regions and their ratings were determined by the level of development of innovative resources. This research identifies areas and mechanisms to ensure balanced sustainable development of the national economy. The findings suggest that sustainable development of the state is affected by the innovative activity of the regions, the sustainable development of which is ensured by innovative enterprises. Transition to the model of sustainable territorial development involves the formation of such conditions and the use of mechanisms under which the natural base of this development is not destroyed, the environment suitable for human existence is preserved and reproduced. The findings of this research support for pursuing a national policy of reducing regional imbalances, and promoting a more balanced and sustainable development of the whole country.

  • Korea experienced rapid urbanization due to high growth of economy. As people left the country and gathered in the city, the size of city has been expanded, resulting in unbalanced development of the land. In addition, it appears in diverse aspects from nationwide phenomenon to the local development in each city unit. In particular, it even tends to become social problems in the metropolitan cities. As a solution for it, this study conducts theoretical consideration on sustainability in the aspect of balanced urban development and suggests measures through analysis on Siheung-city. The result is as follows. First of all, comprehensive approach is required based on sustainability. It is required to derive balanced city development by expanding it to the social, cultural and economic aspects. Second, integrated management policy is required for the original city along with new development. It should be considered together with diverse social and physical aspects. Third, approach from the aspect of city planning is required through consideration on flat city expansion and connection with city space structural. Fourth, in order to foster balanced urban development, it is needed to grope for solutions for imbalanced urban development through the participation of diverse groups such as local residents, private enterprisers, and the non-profit civic groups of the local community along with the mediation among persons interested. And continuous support of administrative authorities should be obtained to create such environment.

  • As a project appraisal tool, the preliminary feasibility study (PFS) has contributed to enhancing the efficiency of public investment decision-making in the Republic of Korea over the last two decades. To overcome the limitations of the efficiency-oriented cost-benefit analysis, the PFS accommodates equity concerns among regions, namely balanced regional development (BRD) analysis. This study attempts to gauge the contributions of BRD analysis to PFS results. Specifically, it addresses how effectively policy efforts to promote decision-making have been implemented in the PFS stage while also considering the balance between equity and efficiency in terms of the trade-off between them, the degree to which they influence the results, and whether the consideration of equity is in fact actually reflected in seriously underdeveloped regions as intended. The study finds that the PFS results over the last two decades have been largely in line with the background and policy objectives. Based on the findings of the study, needs for institutional improvement are suggested, including enhancements in the analysis of regional economic ripple effects and taking into account the psychological factors pertaining to the evaluators in the overall judgment.
