This paper aims to examine the use of the Balanced Scorecard in a not-for-profit organization (the Korea Shipping Association). The KSA has begun using the Balanced Scorecard paradigm in its strategic planning process. In this paper an overview is presented of the basic concepts of the Balanced Scorecard including the financial perspective, customer perspective, internal process perspective, and learning and growth perspective. The accounting system and its pros and cons of the KSA are then surveyed in terms of its performance evaluation. The application of the Balanced Scorecard approach to the KSA is discussed in detail. Implications in using the Balanced Scorecard are discussed. Finally, conclusions regarding the use of the Balanced Scorecard in a not-for-profit organization are presented. Through this paper, the comprehensive understanding of the performance evaluation for not-for-profit organizations as the KSA would be promoted.

Zero-difference balanced (ZDB) functions can be applied to many areas like optimal constant composition codes, optimal frequency hopping sequences etc. Moreover, it has been shown that the image set of some ZDB functions is a regular partial difference set, and hence provides strongly regular graphs. Besides, perfect nonlinear functions are zero-difference balanced functions. However, the converse is not true in general. In this paper, we use the decomposition of cyclotomic polynomials into irreducible factors over 𝔽_p, where p is an odd prime to generalize some recent results on ZDB functions. Also we extend a result introduced by Claude et al. [3] regarding zero-difference-p-balanced functions over 𝔽_pⁿ. Eventually, we use these results to construct some optimal constant composition codes.

Most of Korean survey institutions adopt quota sampling for telephone surveys based on region, gender and age-band. In weekdays, it is well blown that there exist substantial differences in day time in-house rate by individual's socio-demographic attributes. So, quota sampling may induce systematic respondent selection bias. To solve the problem, we propose "time-balanced quota sampling" in which interviewer's call time-band is added as an quota variable. Furthermore, we propose "time-balanced quasi-quota sampling" which is derived by partially relaxing evening time quotas in time-balanced quota sampling. We compare the conventional and the newly proposed quota sampling schemes by drawing Monte Carlo samples from the hypothetical population for which the Korea 2004 time use survey data is assumed.

Many Swedish health care organizations have during the last decade started implementing the Balanced Scorecard (BSC) as a systematic way of following-up and analyzing their activities. However, the knowledge of its use and contribution in a health care context is insufficient. Based on a multiple case study the authors explore the use of the BSC in the Swedish health care services. The authors conclude that the concept in a health care context is used as a quality management tool that make new demands on management. In addition, the authors bring out important factors for a long-term use of the BSC.

A new method is developed for estimating the mean of a population which has a linear trend. The suggested estimator is based on the balanced systematic sampling method and the concept of interpolation and extrapolation. The efficiency of the proposed method is compared with that of conventional methods.

This study discusses Korean speech database that has been designed and constructed for common use, especially focusing on designing a list of words or sentences that covers various phonological environments. As the results, PBW(Phonetically Balanced words) and PBS(Phonetically Balanced Sentences) was selected from balanced text corpus using maximum entropy method. And, implemented workbench for spoken language data acquisition is presented in this paper. The workbench consists of grapheme to phoneme converter, utterance list selection module, speech data editing module, multi-layer labelling module, and phoneme context search module.

This study investigates the impact levels of determinants on the Balanced Scorecard application in evaluating the performance of tourism firms in Hanoi. The tourism industry not only promotes economic development, but also contributes to expanding cultural exchanges and improving people's knowledge. However, Vietnam's tourism industry is under fierce competitive pressure, with the participation of foreign enterprises, with large amount of capital, high professionalism and wide network. The rivalry is happening aggressively on many aspects such as products and human resources. Therefore, tourism firms are in urgent needs of having effective methods to evaluate its performance in order to improve business and development efficiency. This study uses data of tourism firms in Hanoi during 2018-2019. The data used for analysis and regression consists of 135 observations. We use Cronbach's Alpha, EFA and regression model to learn the effect of different variables on the Balanced scorecard application in evaluating the performance. The results show that two determinants, including internal factors of tourism firms (IF) and external factors of tourism firms (EF) had positive relationships with the Balanced scorecard application in evaluating the performance. Based on the findings, recommendations are given for improving the Balanced scorecard application in evaluating the performance of tourism firms in Hanoi.

PURPOSES : This paper aims at the implementation of a balanced scorecard that can be widely applied to modern business management for use in the public road management sector. METHODS : This study applied the newly developed LOS-based balanced scorecard system instead of a traditional Key Performance Index (KPI) for better decision making in asset management planning. As an evaluation technique, a" hierarchical alignment and cascading method" is also suggested. Finally, the suggested system has been empirically applied to a regional government. RESULTS : To provide stable and sustainable road services, the balanced scorecard informs the regional government of needed improvements in its asset management plans regarding budget optimization, structural management, the development of inner-business processes, and human resources. CONCLUSIONS : An LOS-based balanced scorecard for managing road services and organizations in a quantitative manner has been successfully developed and tested through a field study. The developed scorecard is a timely topic and a useful analytical tool for coping with the new phases of an aging infrastructure, tighter budgets, and demand for greater public accountability.

Constrained Bayesian estimates overcome the over shrinkness toward the mean which usual Bayes and empirical Bayes estimates produce by matching first and second empirical moments; subsequently, a constrained Bayes estimate is recommended to use in case the research objective is to produce a histogram of the estimates considering the location and dispersion. The well-known squared error loss function exclusively emphasizes the precision of estimation and may lead to biased estimators. Thus, the balanced loss function is suggested to reflect both goodness of fit and precision of estimation. In insurance pricing, the accurate location estimates of risk and also dispersion estimates of each risk group should be considered under proper loss function. In this paper, by applying these two ideas, the benefit of the constrained Bayes estimates and balanced loss function will be discussed; in addition, application effectiveness will be proved through an analysis of real insurance accident data.

Sensors have limited resources in sensor networks, so efficient use of energy is important. Representative clustering methods, LEACH, LEACHC, TEEN generally use direct transmission methods from cluster headers to the sink node to pass collected data. However, the communication distance of the sensor nodes at low cost and at low power is not long, it requires a data transfer through the multi-hop to transmit data to the sink node. In the existing cluster-based sensor network studies, cluster process and route selection process are performed separately in order to configure the routing path to the sink node. In this paper, in order to use the energy of the sensor nodes that have limited resources efficiently, a cluster-based multi-hop routing protocol which merges the clustering process and routing process is proposed. And the proposed method complements the problem of uneven cluster creation that may occur in probabilistic cluster methods and increases the energy efficiency of whole sensor nodes.
