  • The purpose of this study was to propose a framework and system for an advanced evaluation scale for the Multicultural Family Support Center and its services. For this study, we used the Meta-Evaluation method, which is also known as an 'evaluation of the evaluation.' The data were collected from 134 surveys of individuals working in the Multicultural Family Support Center. The questionnaire consisted of two parts: a) general opinions regarding the present evaluation scale; and b) concrete opinions about the details of the scale. The results indicated several problems and issues for improvement. In light of these results, we suggest that not only do the detailed scales have to be modified to incorporate workers' opinions, but also that the management of the evaluation system itself has to be improved in order to achieve more effective evaluation procedures.

  • For a stability design of steel frames, AISC-LRFD specification recommend to use Alignment Chart and story-based methods in order to determine an effective budding length. Recently, elastic buckling analysis, which is the method that calculate the effective length of members using eigenvalue of the overall structure, has been widely used in practical design of steel frames because this method can be performed effectively and automatically by computers. However, it can in some cases lead to unexpectedly large effective length in column having small axial forces. Therefore, this paper propose a method using elastic buckling analysis, which estimate a proper effective buckling length for all members having a small axial force. For verification of proposed method, it is compared with system based approach and stiffness distribution factor method. As a result, proposed method can rationally solve a problem in some case of column having small axial force. Also, adoption range for proposed method is established.

  • A method of calculating the excess Helmholtz free energy from the average of the bent effective acceptance ratio for two-center-Lennard-Jones liquids has been presented. The bent effective acceptance ratio has been newly composed from the acceptan ce ratio for the potential energy difference between a configuration in the Metropolis Monte Carlo procedure and random virtual configuration generated by the separate parallel Monte Carlo procedure and the Boltzmann factor for half the potential energy difference. The excess Helmholtz free energy was calculated directly from the average of the bent effective acceptance ratio through a single Metropolis Monte Carlo run. Because the separate parallel Monte Carlo procedure was used, this method can be applied to molecular dynamics simulations. For two-center-Lennard-Jones liquids, the average of the bent effective acceptance ratio gave better results than use of the modified effective acceptance ratio in the previous work.

  • Since behaviors of loose, dense, silty sands vary under seismic loading, understanding the liquefaction mechanism of sandy soils continues to be an important challenges of geotechnical earthquake engineering. In this study, 36 deformation controlled cyclic simple shear tests were performed and the liquefaction potential of the sands was investigated using three different relative densities (40, 55, 70%), four different effective stresses (25, 50, 100, 150 kPa) and three different shear strain amplitudes (2, 3.5, 5%) by using energy based approach. Experiments revealed the relationship between per unit volume dissipated energy with effective stress, relative density and shear strain. The dissipate energy per unit volume was much less affected by shear strain than effective stress and relative density. In other words, the dissipated energy is strongly dependent on relative density and effective stress. These results show that the dissipated energy per unit volume is very useful and may contain the non-uniform loading conditions of the earthquake spectrum. When multiple regression analysis is performed on experiment results, a relationship is proposed that gives liquefaction energy of sandy soils depending on relative density and effective stress parameters.

  • Among various methods to build the construction safety, the consecutive improvement by the measuring and evaluating safety management capabilities for the construction participants such as an owner, a contractor, and a supervisor (construction project manager) can be the effective one. Thus, an effective evaluation and grading criteria to provide performance index for the implementation of safety management activities should be necessary. In this regards, the purpose of this study is to verify the adequacy by offering a competency evaluation system for the supervisor's safety capability and by applying the system to some construction sites. The proposed evaluation system was developed on the basis of the principles of safety management & accident prevention, basic elements of safety and health management system, and safety evaluation cases at home and abroad. The trial evaluation showed that the safety management of the construction site is mainly carried out by the contractor and the supervisor's awareness for the safety management is low on the whole. Especially, it is urgent to improve the support system from the supervisor headquarter and to place the dedicated safety management person in the field.

  • Assuming that different spatial types involves the change of observation time to acquire the spatial information, this study intended to analyze the observation time by interior space types and derive the proper time for spatial evaluation. Coming to the study method, in order to analyze the characteristics of observation time in the image evaluation of interior space by types, it looked into the observation time chosen by the testees during evaluation. The findings of this study are as follows: First, the observation time differed by genders and spatial types: men's average time was longest for modern (93.3 sec.) and natural (89.4 sec.) spaces; women's average time was longest for classic space (110.7 sec.), which was the shortest for men. Second, the intensity of observation time zone differed by spatial types: this finding can imply that different design types require different establishment of observation time for evaluation even if the spatial elements are the same. Third, analyzing the distribution of time zones chosen by most testees showed that men's observation time zones were more intensely distributed than those of women. Fourthly, the observation lime for general space could be derived from the gender-based comparison that excluded the difference by types, but considering that different design types lead to different observation time, it could be seen as proper for evaluation of interior space to establish the difference of observation time by spatial types. Finally, Analysis showed the highest preference to the time '(3)'. However, obtaining information presented is the most highly effective time is '(6). Thus, the preferred time zone is different and effective, according to the results of the analysis.

  • Information Technology represents substantial financial investment for government organization. However, it seems that the real goal of IT investment, which is to make government more efficient, effective, and responsible through IT systems, has not been seriously aware of in the government organizations. As a result, despite of large investment in IT over many years, substantial benefits accrued to the work, such as process innovation and work efficiency, have not actually occurred. In this paper, it is argued that, since IT benefits will not be realized without any effective benefits realization efforts, it is needed in IT evaluation to put more emphasis on the efforts. Therefore, it is suggested that appropriate IT evaluation can possibly work as a guideline for deriving the desired benefits through the IT investment. In this study, some of the well known approaches were reviewed about what IT evaluation and IT benefits realization efforts should be. Current evaluation method was analyzed from the perspective of benefits realization. On the basis of the analysis, this study leads to suggestions that improve the current ways of evaluating IT performance, helping government focus on realizing practical IT benefits at work.

  • The main purpose of this study was to comprehensively evaluate the local agenda 21 of Daegu City based on the evaluation model and propose important measures to solve its problems and improve the limitations. As a whole, the evaluation result of the local agenda 21 of Daegu City showed very low score, only 151 points out of 500 points and revealed it was below the level in all three domains of making process, designed content, and evaluation of implementation. The making process got only score below the half in all large indicators of under-standing, driving, and rationality. This unsystematic and irrational process inevitably resulted in ambiguous and proclamatory content mainly expressing willingness to do. This fact means that the local agenda 21 of Daegu City has not served as the comprehensive local environmental plan containing visions, policies, ends and means. It did not suggest evaluation system and institutionalization of evaluation. These results of evaluation suggested that the existing local agenda 21 of Daegu City was neither useful nor effective and thus the totally new local agenda 21 should be prepared. Finally, important measures in making process, designed content and evaluation of implementation were proposed for the remaking.
