  • This research was carried out in order to develop and validate the Korean Version of Working Relationship Scale for Mentally Disabled Persons, which measures the working relationship between a mentally disabled person and his or her case manager. The first step taken to develop this scale was to construct sample items for the Working Relationship Scale using literature research and three focus group interviews of mentally disabled persons who use local mental health services. Secondly, mentally disabled people were surveyed with these sample items and two professors from the department of social work who specialize in mental health social work and two licensed mental health social workers working in the community mental health field reviewed these sample items to select and compile a final version of the scale. Lastly, the scale's reliability and validity was verified through an empirical study of 569 mentally disabled persons who surveyed the final selection of items. An explanatory factor analysis showed that the sample items can be grouped into three factors. Factor 1 is 'Professional Contribution Factor,' which is related to the professional practice of the case manager; Factor 2 is 'Negative Working Relationship Factor'; and Factor 3 is 'Emotional Bond Factor,' which measures the intimacy between the case manager and the mentally disabled person. A confirmatory analysis of the three-factor format that was discovered in the explanatory factor analysis was carried out with the rest of the randomly divided data, which showed that the model demonstrated a goodness-of-fit. The convergence validity between similar concepts appeared to be appropriate as well. Based on these results, the Korean Version of Working Relationship Scale for Mentally Disabled Persons consisting of a final 33 items is developed and proposed and its implications in social work are discussed.

  • The flow of non-rotation atmosphere with uniform stratification and wind past an isolated three dimensional topography obstacle is investigated with three-dimensional hydrostatic and non- hydrostatic numerical model. The characteristic of turbulence created the back of topography obstacle is usually defined by Froude number which is the function of upstream wind speed, the height of topography obstacle, and atmospheric stability. Turbulence tends to be formed more easily at the non-hydrostatic model than hydrostatic model. Especially, the difference between flow patterns of two models generated by isolated obstacle is more clear under low Froude number. The difference of flow patterns can be only seen at relatively low altitude, but at high altitude the patterns of two models are almost same. In this research, wind velocity in the parameters related with Froude number have great sensitivity at responsibility of numerical models. and slop of obstacle is also important factor at the flow pattern regardless of the species of numerical model

  • The objective of this study was to develop evaluation criteria for forest education using the Context, Input, Process, and Product (CIPP) model. To this end, we designed a survey based on expert advice and content analysis of previous studies on the CIPP model and forest education. The survey was conducted on 393 forest education specialists, and Cronbach's α coefficient was set as 0.6 or higher to verify reliability and validity, and to determine reliability by factor. Eventually, 52 out of 57 evaluation items were extracted, and the evaluation indexes were selected through factor analysis as follows: four evaluation indexes for the context dimension, namely "Clarity of goal setting," "Developing conditions for education," "Meeting of requirements," and "Institutional drive"; three evaluation indexes for the input dimension, namely "Acquisition of education infrastructure," "Establishment of operational support," and "Adequacy of assigned manpower"; four evaluation indexes for the process dimension, which were "Adequacy of budget allocation," "Expertise of forest education instructors," "Diversity of programs," and "Public-private academic partnership"; and five evaluation indexes for the product dimension, namely "Effectiveness of perception change," "Influence over the society," "Continuity of improvement in evaluation," "Continuity of education," and "Verification of the effects of education."

  • Despite the importance of and the vast empirical research attention devoted to commitment in channel relationships, several unresolved issues remain. First, although the term commitment is often measured as a single trait, measuring commitment as a single dimension, is problematic for the epistemological depth and methodological sophistication of the instrument. Second, consumer research has seldom considered the complex nature of commitment in consumer markets. This study hypothesized that the multidimensionality of commitment can be separately identified and that the multidimensional factors-LY(Loyalty), ID(Identity), INT(Internalization)-interact differently from those in inter-fun relationships. A conceptualization of commitment holds LY as a central mediator between ID and INT in this study. The data was collected from 491 retail consumers. For the measurement model test, the three-factor model was selected as representing the underlying factor structure in the sample data and the multidimensionality of commitment was confirmed. The conceptualized model, holding LY as a mediator of ID and INT, performed better than the competing model with INT as mediator of ID and LY. The results provide a theoretical contribution in furthering the research on relationship marketing with consumers by suggesting that the consumer commitment structure be presented differently from the organizational commitment.

  • Purpose: This study was conducted to evaluate the validity and reliability of the Korean version of the Sexuality Attitudes and Beliefs Survey (SABS) and to assess SABS for Korean nurses. Methods: The Korean version of SABS was developed through forward-backward translation techniques. Internal consistency reliability and construct validity using confirmatory factor analysis were conducted using PASW+ PC Win (18.0) and AMOS (18.0). Data were collected from 567 nurses who worked in one of six general hospitals across the country. Results: The Korean version of SABS showed a reliable internal consistency with Cronbach's ${\alpha}$ of subscales ranging from .59 to .73. Factor loadings of the 10 items of three subscales ranged from .38 to .83. The three subscales model were validated by confirmatory factor analysis (GFI>.97, RMSEA<.05). Sexuality attitudes and beliefs for Korean nurses were more negative than that of European or American nurses. The SABS scores for Korean nurses were significantly different according to age, marriage, education, clinical experiences, and feeling about sexuality. Conclusion: The Korean version of SABS has satisfactory construct validity and reliability to measure Korean nurses' attitudes and belief toward sexuality. Education is essential to enhance importance and self-efficacy and to relieve barriers to addressing patients' sexuality.

  • This experiment Was carried out under two points of view, from May 1st to the end of 1973. One was the comparative determination of the activation factor of Lead dioxide by kinds in measuring of Sulfur oxides concentration by $PbO_2$ cylinder method, and the other was the comparison that result with the record of auto analyzer. Five measuring sites were selected out of Seoul City. Three kinds of Lead dioxide made in Japan (B,C and D) were compared with Standard $PbO_2$ (A for use in Determination of Sulphur in the atmosphere, purity 99% up) made in British Institution, and monthly measuring was conducted at every sampling site. The recording by auto analyzer (Beckman Model 906-A $SO_2$ Analyzer) was conducted once or twice a month for 24 hours at each sampling site during the same period. And some significant results were obtained. 1. In comparative experiments to determine the activation degree of three kinds of Lead dioxide (B,C and D), the obtained correction factor of B reagent was 1.09, 1.16 in C and 1.30 in D against Standard $PbO_2$ (A). Therefore, it should be in need of standardization or clear statement about the reagents for use, in determination sulfur oxides by $PbO_2$ cylinder method. 2. Generally, the concentration of Sulfur dioxide by wilkins' convertion method from $SO_3$ showed about 20-30% higher than those by Auto analyzer.

  • Party is an important communication method in the 21st century and this tendency is not exceptional in Korea. With this noteworthy phenomenon, this study summarized the concept and history of party first, and then analysed "belief - attitude - behavioral intention" model based on the one-dimensional attitude theory. The variables included in this research were western culture familiarity as belief factor, three variables evaluating the party culture(i.e., non-popularity of party, marketability of party, sociability of party) as attitude factor, and dress code receptiveness as behavioral intention factor. The samples of this study were 498 women in twenties and thirties from metropolitan areas in South Korea. SPSS 12.0 and AMOS 4.0 packages were used for statistical analysis. The results of this research are as follows: First, western culture familiarity had a significant effect on attitude toward party culture. Specifically, western culture familiarity negatively influenced the non-popularity dimension of party and positively influenced the marketability and sociability dimension of party. Second, attitude toward party culture significantly influenced the dress code receptiveness. Consecutively, all of three dimensions about attitude toward party culture positively influenced the dress code receptiveness. Managerial implications were provided.

  • We propose the crack growth rate equation which will model fatigue crack growth rate behavior such that constant stress amplitude fatigue crack growth behavior can be predicted. Constant stress amplitude fatigue tests are conducted for four materials under three stress ratios of R=0.2, R=0.4 and R=0.6. Materials which have different mechanical properties i.e. stainless steel, low carbon steel, medium carbon steel and aluminum alloy are used. Through constant stress amplitude fatigue test by using unloading elastic compliance method, it is confirmed that crack closure is a close relationship with fatigue crack propagation. We describe simply fatigue crack propagation behavior as a function of the effective stress intensity factor range ($\Delta$ $K_{eff}$=U .$\Delta$K) for all three regions (threshold region, stable region). The fatigue crack growth rate equation is given by da / dN=A($\Delta$ $K_{eff}$­$\Delta$ $K_{o}$ )$^{m}$ / ($\Delta$ $K_{eff}$­$\Delta$K) Where, A and m are material constants, and $\Delta$ $K_{o}$ is stress intensity factor range at low $\Delta$K region. $K_{cf}$ is critical fatigue stress intensity factor.actor.

  • The behavior prediction of PAHs in Jinhae Bay using a three-dimensional ecological model(EMT-3D) was examined. A three-dimensional ecological model(EMT-3D) was applied to the simulation of PAHs behaviors in Jinhae Bay of Korea. The computed results of simulation were in good agreement with the observed values. The result of sensitivity analysis showed that photolysis coefficient and extinction coefficient were important factors in the variation of dissolved PAHs, and POC partition coefficient was important factor in the variation of PAHs in particulate organic matter. In the case of PAHs in phytoplankton, bioconcentration factor of plankton was the most significant and the most effective in all. In simulations of 30%, 50% and 80% reduction in total loads of PAHs, the concentrations of dissolved PAHs were shown to be lower than 24 ng/L, 20 ng/L and 16 ng/L, respectively.

  • Most traffic information that drivers receive while driving are stored in their short-term memory and disappear within a few seconds. Contemporary modeling approaches using a dummy variable can't fully explain this phenomenon. As such, this study proposes to use utility functions of real-time in-vehicle traffic safety information (IVTSI), analyzing its safety impacts based on empirical data from an on-site driving experiment at signalized intersection approach with a limited visibility. For this, a driving stability evaluation model is developed based on driver's driving speed choice, applying an ordered probit model. To estimate the specified utility functions, the model simultaneously accounts for various factors, such as traffic operation, geometry, road environment, and driver's characteristics. The results show three significant facts. First, a normal density function (exponential function) is appropriate to explain the utility of IVTSI proposed under study over time. Second, the IVTSI remains in driver's short-term memory for up to nearly 22 second after provision, decreasing over time. Three, IVTSI provision appears more important than the geometry factor but less than the traffic operation factor.
