The demand of elderly care facilities due to aging population has been increased and the trend of developed countries implies the necessity of innovate approach for elderly care in Korea. The purpose of this research is to evaluate the flexible elderly housing alternative which has been introduced showing adaptability and small scale. This elderly housing alternative was designed to fulfill the condition of residential facilities for various aging phases from the independent elderly to dependent elderly. The workshop method was used for pre-evaluation of the flexible elderly housing alternative from the viewpoint of administrators, care givers and the elderly. The pre-evaluation is to estimate the facility before finalizing the design so that it facilitates more effective and suitable plan by reducing the trial and error beforehand, unlike the post-evaluation. Major responses of plans were positive and the needs for improvement about some concerns were revealed. Thus, relevant aspects of architectural drawings were amended according to workshop participants' needs and features that require to be reflected during further planning procedures were also improved. The result of this research will develop the flexible elderly housing alternative and contribute to foster environment for the elderly as well.

A total of 1,367 first lactation records of daughters of 81 sires, having 5 or more progeny were used to evaluate sires by 3 different methods viz., least squares (LS), best linear unbiased prediction (BLUP) and derivative free restricted maximum likelihood (DFREML) method. The highest and lowest overall average breeding value of sires for first lactation 305 days or less milk yield was obtained by BLUP (1,520.72 kg) and LS method (1,502.22 kg), respectively. The accuracy, efficiency and stability of different sire evaluation methods were compared to judge their effectiveness. The error variance of DFREML method was lowest ($191,112kg^2$) and its coefficient of determination of fitting the model was highest (33.39%) revealing that this method of sire evaluation was most efficient and accurate as compared to other methods. However, the BLUP method was most stable amongst all the methods having coefficient of variation (%) very near to unadjusted data (18.72% versus 19.89%). The higher rank correlations (0.7979 to 0.9568) between different sire evaluation methods indicated that there was higher degree of similarity of ranking sires by different methods ranging from about 80 to 96 percent. However, the DFREML method seemed to be the most effective sire evaluation method as compared to other methods for the present set of data.

A nuclear power plant is composed of a number of primary components. Maintaining the integrity of these components is one of the most critical issues in nuclear industry. In order to maintain the integrity of these primary components, a complicated procedure is required including regular in-service inspection, failure assessment, fracture mechanics analysis, etc. Also, experts in different fields have to co-operate to resolve the integrity issues on the basis of inspection results. This integrity evaluation process usually takes long, and thus, is detrimental for the plant productivity. Therefore, an effective safety evaluation system is essential to manage the integrity issues on a nuclear power plant. In this paper, a web-based fatigue life evaluation system for primary components in nuclear power plant is proposed. This system provides engineering knowledge-based information and concurrent and collaborative working environment through internet, and thus, is expected to raise the efficiency of integrity evaluation procedures on primary components of a nuclear power plant.

This study developed effective assay method of pharmaceutical quality control was developed by near-infrared spectroscopy (NIRS). The calibration equation model of assay was developed by 2nd deriviative PLS(Partial Least Squares) regression method with NIRS over the wavelength range from 1100 to 1400nm using diazepam tablets (2mg, 5mg). Although diazepam tablets are made by 5-different manufacture, they have similar formulation. When the correlation was compared with values by NIRS and HPLC, the R-2s and standard error of calibration (SEC) for 2mg were 0.9300 and 0.98%, the R-2s and SEC for 5mg were 0.9165 and 0.63%. The validation of the calibration equation model yield that the R-2s and standard error of prediction (SEP) for 2mg were 0.9611 and 0.995%, the R-2s and SEP for 5mg were 0.9114 and 0.842%. The method was validated on assay method for diazepam tablets by the calibration equation.

With the advent of the 4th Industrial Revolution, the importance of solving problems through computing has been emphasized, and software education to improve computational thinking as a core competency has been designated as an essential subject. In order for education for computational thinking to be effective, appropriate tools for evaluating computational thinking must be supported. While studies on computational thinking have been conducted in the meantime, there have been no systematic studies on such evaluation-related studies. This study analyzed the related studies on the computational thinking assessment conducted in Korea and analyzed the previous research of the evaluation tools, evaluation criteria, and evaluation methods. Based on this, the implications for the study of computational thinking evaluation method were suggested.

Purpose: This paper provides a method to identify cost-effective standards by analyzing the relationships between certified company and standards. It also aims to provide a evaluation model to establish a certification portfolio strategy of institutions. Methods: By analysing the networks of certified company and certification standards, this paper developed an evaluation model of standards. The evaluation model uses an index(Certificated Standard Evaluation Index; CSEI) to assess the value of standards. Results: To verify the applicability of the evaluation model, the proposed model and the CSEL index have been applied to certification standards of Korean Standard Association. The results show that the evaluation model can effectively identify potential customers and thereby establish a certification portfolio strategy. Conclusion: The main contribution of this study is a provision of a new approach to certification portfolio strategy by evaluating the value of standards. The proposed model is expected to provide implications for the certification portfolio strategy.

The purpose of this study was to develop criteria for evaluating final reports of free inquiry activity and to apply developed evaluation criteria to free inquiry activity reports. 323 inquiry reports submitted to internal contests in the elementary schools as well as 189 award-winning ones from the inquiry competition for students in Seoul were collected. Nine categories and 18 sub-categories of evaluation criteria were derived by collecting reports analysis, literature reviews and interviews with 15 elementary school teachers. Criteria for each sub-category were organized into three steps and 12 elementary school teachers assigned scores for each sub-category, which were averaged. 132 including both award-winning and general reports were evaluated based on the developed evaluation criteria. The content validity and the reliability across scorers were significant. Furthermore, award-winning and general reports were significantly distinguished by the developed criteria in terms of all sub-category scores. The developed evaluation criteria will be an effective tool to asses student's free inquiry activity.
