As traditional ways of evaluation prove to be ineffective in evaluating the effect of interactive multimedia physical education (PE) teaching, this study develops a new evaluation model based on the simulated annealing algorithm. After the evaluation subjects and the principle of the evaluation system are determined, different subjects are well chosen to constitute the evaluation system and given the weight. The backpropagation neural network has been improved through the simulated annealing algorithm, whose improvement indicates the completion of the evaluation model. Simulation results show that the evaluation model is highly efficient. Compared with traditional evaluation models, the proposed one enhances students' performance in PE classes by 50%.

In order to evaluate the cost effectiveness of seismic isolation for bridges in low and moderate seismic region, a method of calculation minimum life-cycle cost of seismic-isolated bridges under specific acceleration level and soil condition is developed. Input ground motion is modeled as spectral density function compatible with response spectrum for combination of acceleration coefficient and site coefficient. Failure probability is calculated by spectrum analysis based on random vibration theories to simplify repetitive calculations in the minimization procedure. Ductility of piers and its effects on cost effectiveness are considered by stochastic linearization method. Cost function and cost effectiveness index are defined by taking into consideration the characteristics of seismic isolated bridges. Limit states for calculation of failure probability are defined on superstructure, isolator and pier, respectively. The results of example design and analysis show that seismic isolation is more cost-effective in low and moderate seismic region than in high seismic region.

This study has uncovered some important relationships among employees perceptions of distributive justice and procedural justice and organizational commitment and job satisfaction and organizational effectiveness. The present study attempts, first, to identify the perceived justice in promotion and transfer, performance evaluation, pay raise, job allocation and job fire. Second, to determine the relative importance of DJ(distributive justice) and PJ(procedural justice). Add to that two's justice's impact organizational committment, job satisfaction and to examine relationships of organizational committment, job satisfaction. Third, to examine relationships of organizational committment, job satisfaction and organizational effectiveness. The research is the identification of a modest but significant relationship between the two justice and organizational commitment and job satisfaction and organizational effectiveness. The result make it clear that employee find that right personnel management of fairness.

This study analyzes the contents of low birthrate measures by the government and their effectiveness. The discussion on the measures being promoted by the government is conducted by considering the analysis on the cause of low birthrates, introduction of overseas policies and government policy propositions, etc. The evaluation on effectiveness is conducted by considering the recognition of the policies by women who are the subject of childbirth and preceding studies. Low birth rates are not the problem of an individual anymore, but a task that the whole of society has to resolve. The comprehensive measures should be made including the elements that influence birth rate such as reducing the cost of raising a child, creating a favorable environment in society and worksite, and improving the nurturing environment, etc.

Since 2000 fry releasing programs in Korea have significantly expanded in order to support the commercial fishing industry through recruitment enhancement of targeted species. Here we investigate the economic effectiveness of the Olive flounder (Paralichthys olivaceus) fry releasing program in Korean waters. The market survey method was used in our analyses. Results show that the B/C ratio, as an indicator of economic evaluation, is 2.56 in the East Sea region, 9.45 in the South Sea region, and 1.34 in the West Sea region, which indicates that the fry releasing program is economically feasible but the economic effectiveness varies from region to region.

'우리나라 공공도서관에 대한 평가지표 연구'의 후속 연구인 본 논문은 공공도서관의 효과성 지표와 차원(요인)을 설정하는 것을 목표로 하고 있다. 설문지 조사를 위해 전국 공공도서관 중 175 개관을 표본으로 서정하고, 도서관 관계자 집단들에게 자신이 근무하는 도서관의 성과를 평가하도록 하였다. 설문지 결과는 요인 분석(factor analysis) 방법으로 11개의 효과성 차원으로 추출되었는데, 이 차원들은 조직효과성의 일반적인 4가지 모델에 적합한 것으로 판명되었다.

This study is aimed to analyze economic effectiveness of the sea cucumber seed releasing program in Gyeongsangbuk-do region. Based on the surveyed data, the production value of released sea cucumber and the seed releasing program cost are estimated and compared to determine the economic validity of the sea cucumber seed releasing program. Results show that the B/C ratio, as an indicator of economic evaluation, is 2.0, indicating that the sea cucumber seed releasing program in Gyeongsangbuk-do region would be economically feasible under the current production and market conditions. Sensitivity analyses of main variables indicate that the economic effectiveness can be increased when the recapture rate would be increased and the seed price of sea cucumber would be decreased.

This study suggests the effectiveness of an "extended" power system evaluation methodology based on LCA and energy input-output analysis techniques. This "extended" evaluation methodology is designed to incorporate total energy system costs through fuel cycle and external costs, including CO$_2$abatement cost. As an empirical test, we applied the methodology to orimulsion-fired power generation technology and found that orimulsion could be considered as in attractive base-load power generation fuel in terms of economic and environmental aspects, compared to conventional coal-fired power plant.

Due to the pressure of opening electric power market, the transmission system reliability evaluation is being more important. This paper presents a reliability evaluation method for a specific area using the elastic power system frequency decline characteristic. The practicality and effectiveness of this methodology is illustrated by a case study.

This paper presents an evaluation criteria of an information system availability for guaranteeing availability (service target level) from the perspective of the SLA contract and its technical point of view. In order to verify the effectiveness for information system failure and availability guarantee measures, three cases were examined. In summary, the failure time was reduced by 32% ~ 62% after applying the availability guarantee measure, verifying the excellence in the evaluation of an information system availability.
