Safe, fast, efficient and effective railway is a main factor of economic development level of every country. This paper uses the DEA method to evaluate and compare the efficiency of 12 Regions of RAI. In addition, we introduce the reference(s) unit(s) for every inefficient region, and determine the amount of input decrease and/or output increase need to become them efficient. Findings indicate that in 2006, 4 regions of 12 are in Constant Return to Scale (CRS) status and 7 of them in Variable Return to Scale (VRS), and the average efficiency is 0.730 and 0.888, respectively. In other words, RAI works 27 percent under its capacity. More over results indicate that Hormozgan, Khorasan, Tehran and Isfahan Regions have the most efficiency respectively. The results show that the 8 regions, have been working in Increaser Return to Scale and 4 reminder Regions in Decrease Return to Scale. According to this results, we submit the suitable suggestion for improve the efficiency of the inefficient regions.

This study evaluates the effectiveness of smartphone detox program for smartphone addiction among university students. To reduce the rate of smartphone addiction and its negative effects on physical, mental and social wellness, a six-session program was applied to sixteen participants who voluntarily completed the entire program and responded to pre-post survey. Smartphone Addiction Proneness Scale (SAPS) was used for smartphone addiction assessment with Mental Health Scale, Positive Psychological Capital Scale for mental wellness and Self-Management Scale for physical and social wellness. Results received after the program indicated that, smartphone addiction and mental health scores decreased significantly while the average scores of self-management and positive psychological capital increased respectively. Furthermore, the rate of high-risk group decreased, and the participants, affirmed in their self-evaluation report that excessive use of smartphone negatively affects their body, mind and interpersonal relationship. Thus, smartphone detox program is effective in reducing smartphone addiction and improving the students' wellness.

The purpose of study was to develop and validate Korean Sleep Scale A which can be easily administrated by nurses for a wide range of adult subjects. Dimensions of sleep concept were derived by literature review. Previously developed sleep sclaes were also analyzed in order to develop scale items. The Korean sleep scale A was structured as a 15 item, 4 point likert type scale. The Scale was tested an 298 female and male adult subjects after pilottest and content validation. The results showed reliability by internal consistency of Cronbach's α=.75 Construct validity was tested by factor analysis and known group technique. Factor analysis showed 4 factors-sleep pattern, sleep evaluation, sleep result, and cause of sleep disturbance. These four factors explained 55.9% of total variance. Correlations between factors ranged from .15-.32. There was correlation among Korean Sleep ScaleA score, Verran and Snyder-Halpern(VSH) Sleep Scale score, and sleep satisfaction scale score, r=.71(p=.00), r=.51(p=.03), respectively, These study results partially support reliability, construct validity, and criterion related validity of Korean Sleep Scale A. Further validation study is required with other subjects and other settings.

The purpose of this study was to develop the evaluation scales that can access hierarchically the lifelong education field training program based on relevant stakeholders. To fulfill this purpose, both qualitative and quantitative research methods were applied. First of all, four groups of stakeholders were selected such as trainees, professors, field instructors, and program inspectors. The in-depth interviews with 13 experts in the field were conducted, and as a result, the scale with hierarchy of evaluation area, evaluation section, and evaluation item for each stakeholder was developed. In order to verify the content validity of the evaluation scales, delphi surveys for each stakeholder were conducted, using 35 expert panels. After delphi survey, the scale was applied to 90 trainees, 22 professors, and 31 field instructors. SPSS program was used to analyze the descriptive statistics, validity, and reliability. Finally, the evaluation scale of the trainer was identified as 8 evaluation areas, 14 evaluation sections and 51 evaluation items. And the professor's scale consisted of 6 areas, 10 sections and 40 items. The field instructor's scale was determined as 3 areas, 7 sections and 31 items, and the program inspector's evaluation scale was confirmed as 7 areas, 15 sections, and 32 items.

In complex industrial world, many companies make every effort to analyze their competition capability through various performance evaluation tools to cope with rapidly changing business environment. Among evaluation tools the balanced scorecard (BSC), put forward by Kaplan and Norton in 1992, is a strategic performance management tool for measuring whether the smaller-scale operational activities of a company are aligned with its larger-scale objectives in terms of vision and strategy. The BSC tool offers a comparative advantage over others to evaluate the objective achievement of a company by linking its strategic objectives with operational KPI. In this paper, we introduce a case that the BSC performance evaluation system was implemented based on product data management and applied it to the business process. Specially, we shows a implementation procedure to derive discipline-specific topics and key performance metrics.

To evaluate the value of a preserved tree as rural landscape resource, the growth environment and health condition was investigated, and the image evaluation was implemented on land~ape architectural major undergraduate students for zelkova trees in Yesan-gun. The image evaluation results of zelkova trees were as followings; 1) Typical image of preserved tree examined by Semantic Differential Scale were 'Old', 'Big', and 'Good'. 2) The 'big' image of zelkova tree and the height of tree, the width of tree crown, the breast girth of tree, the root girth of tree, the external formation of tree, and the health of tree bark is mutually related. Especially, the correlation between the 'big' and the external formation and the width of tree crown is high. 3) Typical image of preserved tree examined by Likert Scale were 'Natural', 'Green', 'Peaceful', and 'Rural'. 4) The preservation necessity for preserved tree was highly related with the state of ground, and the management necessity for preserved tree was highly related with contamination level and the state of ground. The appropriate management plan for preserved tree are proposed to improve the quality of rural landscape(basis of these results).

Recently, need for the development of the quantification of subjective evaluation is growing for the production of high-touch and high-tech textile products. In this study, Fuzzy theory is utilized for the evaluation of the wear comfort of the various blouses. Result of a new evaluation method and factor scores, validity of the new evalution technique adopted fuzzy theory was crosschecked with the results of fator analysis and factor scores. As results, fuzzy theory was proved to be adequate methodology to objectify the subjective evaluation of the adequacy of clothing which is worn. When DUNCAN'S multiple comparion among median of the fuzzy composite score were compared with the results of factor score, the sensitivity of the test methods tends to increase. Therefore, it is suggested that fuzzy weighted checklist is an alternative evaluation scale for the subjective comparison of the textile products. In addition, individual median of fuzzy composite score value should be treated by statistical for the sensitive analysis of subjective evalution.
