Nowadays, the administration is strongly driving self-innovation including public sector to solve problems continuously pointed out as issues of public sector such as the low management achievement, the low productivity and costliness structure, the low ability coping with market changes and ineffectiveness in managing organization. The core of such renovation is the systematic performance management. Provincial public enterprises are also required to furnish system that can measure management results accurately and make payment according to measured results under autonomous management system to raise management efficiency and strengthen competitive power. In this paper, we design framework for measuring management results of provincial public enterprises based on Balanced Scorecard and show the example applied to Gwangiu Metropolitan City Environmental Installations Corp (GEIC).

This paper suggests a dynamic balanced scorecard (DBSC) model employing the concept of system dynamics (SD), which could overcome the limitations inherent in the conventional balanced scorecard (BSC) and facilitate strategic learning process in organizations. The BSC has been a successful framework for measuring an organization＇s performance in various Perspectives through translating an organization＇s vision and strategy into an interrelated set of key performance indicators and specific actions. The BSC, while having significant strengths over traditional performance measurement methods, however, has its own limitations, due to its static nature, such as overlooking two-way causation between performance Indicators and neglecting the impact of delayed feedback flowing from the adoption of new strategies or policy changes. To overcome these limitations, we employs SD, a methodology for understanding complex systems where dynamic feedback among the interrelated system components significantly impact on the system outcomes. The SD simulation model in the form of DBSC we suggest in this paper would serve as a useful strategic learning tool for facilitating an organization＇s communication process through various scenario analyses as well as predicting the dynamic behavior pattern of their key performance measures over a future time frame. For the demonstration purpose, we apply the DBSC model to Korea Coal Corporation (KoCoal ) BSC case.

The purpose of this study was to determine differences in perception of weight management, balanced food intake, knowledge of obesity, and nutrition knowledge in university students. The average weight and height of male subjects were $175.0{\pm}5.7cm$ and $69.1{\pm}11.8kg$, whereas those of female subjects were $161.7{\pm}5.0cm$ and $51.7{\pm}6.9kg$, respectively. Average scores for balanced food intake were not significantly different between male and female students. The total number of correct answers for obesity knowledge was not significantly different according to gender, but four responses related with losing weight showed higher perception scores in females compared to males (p<0.05). The total number of correct answers for nutrition knowledge was not significantly different between males and females. The average BMI of male and female subjects were $22.5{\pm}3.44$ and $19.7{\pm}2.21$, respectively, ranged in normality. Self-evaluation of body shape was mostly in the normal or standard range in both males and females, but females showed a higher perception rate of chubby or fat than males. The percentages of interest in weight management was 36.0% in males and 50.8% in females, with higher interest in female subjects (p<0.01).

Purpose: The orthogonality and trace optimal properties are desirable for constructing designs of experiments. This article focuses on the determination of the sizes of experiments for the balanced trace optimal resolution-V fractional factorial designs for 2-level factorial designs, which have near-orthogonal properties. Methods: In this paper, first we introduce the trace optimal $2^t$ fractional factorial designs for $4{\leq}t{\leq}7$, by exploiting the partially balanced array for various cases of experimental sizes. Moreover some orthogonality criteria are also suggested with which the degree of the orthogonality of the designs can be evaluated. And we appraise the orthogonal properties of the introduced designs from various aspects. Results: We evaluate the orthogonal properties for the various experimental sizes of the balanced trace optimal resolution-V fractional factorial designs of the 2-level factorials in which each factor has two levels. And the near-orthogonal 2-level balanced trace optimal resolution-V fractional factorial designs are suggested, which have adequate sizes of experiments. Conclusion: We can construct the trace optimal $2^t$ fractional factorial designs for $4{\leq}t{\leq}7$ by exploiting the results suggested in this paper, which have near-orthogonal property and appropriate experimental sizes. The suggested designs can be employed usefully especially when we intend to analyze both the main effects and two factor interactions of the 2-level factorial experiments.

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.

By the way, in light of the knowledge, even public institutions are paying much attention to the management of IT assets for achieving organizational goals. Recently, some public institutions adopt balanced scorecard for enhancing efficiency in operations and management of total administrations. To be interested, some key performance indicators(KPI) of the balanced scorecard reflect the three aspects of IT assets and their possible outcomes. The main focus of this study is to investigate whether there is positive effects of IT asset management through balanced scorecard at public institutions. Specifically, we selected and classified KPIs into different categories depending on three aspects of IT assets, internal process change, and organizational outcomes. To address relationships of KPIs among the categories, we specified each category and developed as a variable respectively. A middle-sized city provided us with 138 KPIs for the development of scales.

Many companies are struggling with the issue of performance measurement because a generally accepted framework does not exist. The Balanced Scorecard is designed to help firms that have historically overemphasized short-term financial performance. In this article, we discuss the interrelation between supply relationship and BSC. The Balanced Scorecard to measure quality performance with respect to supply relationship is suggested. Based on the survey of 84 venture firms, the validity of the measurement tool is tested statistically. Consequently, it was found that the suggested items have validity to measure supply relationship quality performance

Irrigation water has been mainly used for paddy rice. Irrigated paddy land tends to be recently converted to land for green house, farm house, and rural-industrial complex. Consequently, demand of water for crops, domestic & industrial, rural recreations, small-scaled hydropower, livestocks, and environment in the rural area, so called rural water, is rapidly increasing. In order to supply rural water, water in the existing irrigation reservoir could be enlarged by repairment of irrigation canal and reinforcement of irrigation reservoir, and be saved by the operation rule curve, utilization of dead water, and balanced storage management.
