  • The purpose of this study is to investigate validation of the Recovery Assessment Scale(RAS) for Korean Version using Rasch analysis. This study included 60 patients who had chronic schizophrenia and were aged 18 or older. The data were analysed using a Rasch analysis to investigate whether the persons and items fit, the distribution of item difficulty and the appropriateness of the rating scale. 1 out of 60 subjects were found to not fit. 3 out of 24 items were also found to be misfit. The misfitted items was 'I believe that I can meet my current personal goals','Even when I don't care about myself, other people do. ','Coping with my mental illness is no longer the main focus of my life.'. Of the appropriate items, the most difficult was 'I can handle what happens in my life' and the easiest was 'Something good will eventually happen'. The RAS rating scale was shown to be appropriate for patients who had chronic schizophrenia. The item separation reliability was .70, and the person separation reliability was .94. Further studies are needed to investigate validity and criterion cut-off score for many patients with chronic mental illess.

  • The importance of selection methods of secondary school teachers have gathered attention due to their enormous influence on the pre-service education programs. However, scholars and practitioners are skeptical about the effectiveness of the measures, especially under the condition of teacher oversupply found in South Korea and China. Based on this problem statement, this study seeks to compare the secondary teacher employment methods of the two countries to better understand the situations as well as to draw implications for improvement. We reach the following conclusions through comparative analyses. First, the reforms of the teacher employment system in both countries have been triggered by the quantitative supply concerns not by the qualitative concerns. Second, both countries require teaching license as a precondition of employment, while their quality assurance measures for the license reveal critical limitations. Third, both countries have attempted to improve selection methods; nevertheless, oversupply of prospective teachers makes objectivity and fairness more important than the appropriateness. Based on the conclusions, policy implications focusing on the quality-oriented approach are suggested in order to employ effective secondary teachers who can contribute to the quality improvement of school education.

  • This study aims to investigate the context of materials in literature textbooks and the awareness about the educational value of classical literature, as part of an interest in literature education phenomena. This study accepts the premise that textbooks affect the practice of classical literature education and, in particular, materials in textbooks are chosen according to the intentions, demands, and perspectives of education in specific social conditions. I divided the educational value of classical literature into two categories, classical and literary value, and investigated the actual conditions and context of materials of literature textbooks based on the 2009 revised curriculum and the 2011 revised curriculum. Classical literature is generally alienated and excluded; contemporary literature materials are mostly included and organized in the domains of 'the role of literature', 'reception and production of literature' and 'literature and life.' In addition, the tendency to heighten classical value and diminish literary value is deepening. In order to solve the problem that classical literature is only included as the product of the past, changes must be made not just to the curriculum, which are external changes, but to the awareness of the essence of classical literature, which are internal changes. Above all, generality as 'literature' and the sense of distance about space and time as 'classic' should be connected to various relationships which respond to problematic situations and the demands of learners. Based on the relationships, we can expect a rich diversity of contexts and aspects of included classical literature. In addition, an extension of the width and scope of included classical literature is anticipated. The reduction of workload, the advent of the concept of capability and the dissolution of traditional literature concepts are the changes of external environment, which is continuously requiring renewed investigation into classical literature beyond simple appropriateness.

  • The purpose of this study was to evaluate the effect of parenting stress on marital conflict in dual earner couples with children in early childhood. Actor and Partner Interdependence Model (APIM) was conducted in order to identify how parenting stress affect husband and wife, respectively and how this make the actor effect as well as the partner effect regarding the marital conflict. The research was conducted with 629 married couples from the forth wave of the Panel Study of Korean Children (PSKC) data. In order to examine the relationships between the variables and to evaluate the appropriateness of the research model, structural equation model was used. The results showed that the parenting stress had significant positive effect on the marital conflict. The partner effect of parenting stress was significantly positive. This result implies that the mutual dependence in dual earner couple's marital conflict and parenting stress should be considered in the process of intervention. In other words, to improve the effectiveness of intervention, practitioners should treat couples together rather than being focused on individuals.

  • What is particularly noteworthy from Korean and foreign railway tunnel disaster prevention standards is that for the sake of rapid evacuation, more stringent standards for provision of evacuation passages, which require high cost, are being applied. Korean standards stipulate that passage installation should be determined in accordance with the level of risk through a QRA analysis of each tunnel with 1km or longer length. As, however, detailed application criteria as fire occurrence probability, fire occurrence scenario, size of fires and evaluation criteria for level of social risk are not available, additional costs may be incurred due to excessive design. Thus, standards of an appropriate level need to be established. With this backdrop, this study selects detailed application conditions of a reasonable and appropriate level through a study and analysis of relevant documents and analyzes the maximum length of tunnels to which the application of evacuation passages, or the application major evacuation promotion facilities, can be relaxed, together with a QRA analysis of model tunnels (for high speed rail) with different tunnel lengths. In addition, the QRA results on tunnels, including those on the Honam high-speed rail, and analysis results for the model tunnels, are compiled, ; the ultimate results are compared with Korean and other countries' standards related to evacuation promotion facilities, As a result, The appropriateness of application standards are reviewed. These results are expected to be utilized as basic material for establishing a reasonable disaster prevention plan that will consider safety and economies.

  • Precipitation is one of a major causes of landslides by rising of pore water pressure, which leads to fluctuations of soil strength and stress. For this reason, precipitation is the most frequently used to determine the landslide thresholds. However, using only precipitation has limitations in predicting and estimating slope stability quantitatively for reducing false alarm events. On the other hand, Soil Moisture (SM) has been used for calculating slope stability in many studies since it is directly related to pore water pressure than precipitation. Therefore, this study attempted to evaluate the appropriateness of applying soil moisture in determining the landslide threshold. First, the reactivity of soil saturation level to precipitation was identified through time-series analysis. The precipitation threshold was calculated using daily precipitation (Pdaily) and the Antecedent Precipitation Index (API), and the hydrological threshold was calculated using daily precipitation and soil saturation level. Using a contingency table, these two thresholds were assessed qualitatively. In results, compared to Pdaily only threshold, Goesan showed an improvement of 75% (Pdaily + API) and 42% (Pdaily + SM) and Changsu showed an improvement of 33% (Pdaily + API) and 44% (Pdaily + SM), respectively. Both API and SM effectively enhanced the Critical Success Index (CSI) and reduced the False Alarm Rate (FAR). In the future, studies such as calculating rainfall intensity required to cause/trigger landslides through soil saturation level or estimating rainfall resistance according to the soil saturation level are expected to contribute to improving landslide prediction accuracy.

  • A quantitative risk assessment method for quantitatively evaluating the fire risk in designing a road tunnel disaster prevention facilities has been introduced to evaluate the appropriateness of a disaster prevention facility in a large tunnel through which all vehicle types pass. However, since the quantitative risk assessment method of the developed can be applied only to the large sectional area tunnels (large tunnels), it is necessary to develop a quantitative risk assessment method for road tunnels passing only small cars which has recently been constructed or planned. In this study, fire accidents scenarios and quantitative risk assesment method for small road tunnels through small cars only which is based on the methods for existing road tunnels (large tunnels). And the risk according to the distance between cross passage is evaluated. As a result, in order to satisfy the societal risk assessment criteria, the distance of the appropriate distance between cross passages was estimated to be 200 m, and the effect of the ventilation system of the large port exhaust ventilation system was quantitatively analyzed by comparing the longitudinal ventilation system.

  • The purpose of this study is to validate scale of deteminants for watching Korean traditional music performances to activate the market by procuring and increasing Korean traditional music performance consumers that exhibit generally low preference in the performance market. Accordingly, FGI was conducted on seven employees and professionals in the arts and cultural sector and then open survey results were categorized into eight factors and a total of sixty-five items using the KJ method to find the viewing decision factors per consumer type of Korean traditional music performances. Afterwards, a six-factor and thirty-five items were extracted after conducting an exploratory factor analysis and confirmatory factor analysis was conducted to verify the structural appropriateness, and then the feasibility of the composition of Korean traditional music performance viewing decision factor scale was verified. Results of the analysis showed that first, for general Korean adults making decisions to view Korean traditional music performances, there was positive impact in the order of interest-creating factors, fame and talent factors, emotional and information factors, creativity factors, reasonable price factors, and social relation factors. Second, the general tendency of decision factors to view Korean traditional music performances showed relatively high levels in reasonable price factors and interest-creating factors among the Korean traditional music performance viewing decision factors, while emotional and information factors were found to be relatively low.

  • This study was conducted to investigate and analyze the designation status of the Local Wildlife Conservation Ordinance for the conservation and management of wild fauna and flora, and to elucidate the problems and improvement directions. We compared and analyzed the provisions of the wildlife conservation ordinance of 17 regional local governments. After that,the designation status of Wildlife Protected by City/Do was investigated and the appropriateness was confirmed based on guidelines and laws. The ordinances related to wildlife were enacted in all municipalities, and provisions such as selection criteria, protection measures, and act limitations were commonly reflected. The provisions were varied depending on the characteristics of each local government, including details of flag species, the addition of species in the restoration promotion plan as criteria for selection and provision of protection and restoration of habitats. Since 2006, when the wildlife protected by City/Do designation and protection guidelines have been established, the protected wildlife have increased sharply, and there has been newly designated regional local government within the past one or two years. However, in some local government, protected wildlife has been designated for more than 10 years, and there are many that do not meet the selection criteria. Therefore, more scientific and objective selection criteria and methods should be constructed for the selection of species suitable for the purpose of the Wildlife protected by City/Do.

  • The purpose of this study was to verify the construct validity of the Sensory Profile for children with congenital cerebral palsy. Parents of 87 children(the ages of 3 to 10) with congenital cerebral palsy participated in this study. The data were analyzed through Winstep version 3.81 using the Rasch model to examine the uni-dimensionality of the fit of each item, the distribution of difficulty of each item, and the reliability and appropriateness of the rating scale. Based on a Rasch analysis, four out of the 87 children were considered to be inappropriate participants, and 15 item of the Sensory Profile was determined to be an inappropriate item. The items of high-level difficulty are needed as new items of the Korean Sensory Profile. The rating scale of three categories were appropriate than those of the five categories. The person and item separation reliability of three categories was above 0.90, which is a relatively excellent value. Finally, it will be need to verify of validity for Korean version of Sensory Profile, to develop new item of a high level of difficulty and convert into three point rating scale.
