Objective : The purpose of this study was to develop an assessment tool to measure Korean occupational balance. Methods : From March 2017 to July 2019, preliminary questionnaire was prepared through analysis of previous research and expert focus meeting, and preliminary questions were selected through the Delphi survey. In order to verify the validity of the items, Rash analysis was conducted to analyze the persons and items fitness, the distribution of item difficulty, separation reliability, and the appropriateness of the rating scale. Results : Among 141 subjects, 9 (6.38%) in time use and 11 (7.80%) in the occupation area were inappropriate subjects. As a result of analyzing the appropriateness of the items except for the inappropriate subjects, the 3 items were judged as ineligible items, but 1 item of the occupation characteristics was finally deleted based on the theoretical and clinical grounds. In the analysis of the scale, 4 points were more appropriate than the 5 point scale, and the separation reliability was .86~.94. Finally, 3 categories (time use, occupation area, occupation characteristics) and 18 items were selected. Conclusion : The occupational balance assessment tool was selected three categories and 18 questions finally, three categories and 18 questions, and was developed on a four-point Likert scale. Further research needs to prove the concurrent validity of the K-OBA and to analyze the factors that influence the occupational balance.

Objectives: To evaluate the learning achievement and satisfaction levels for the Field Epidemiology Specialist Training Program (FESTP), on infectious disease control between March 19 and October 31, 2002. Methods : The FESTP was designed as a set of 84 hours curricula including lectures, discussions, self-studies, and field practicals, and organized both centrally and locally by the Division of Communicable Disease Control of the National Institute of Health and 11 universities. Before and after the program, a questionnaire survey on the educational need (49 items) and satisfaction (15 items) was conducted on 484 trainees, who were responsible for communicable disease control and immunization at 242 regional health centers. The data were analyzed with paired t-tests for comparison of the educational needs between the pre and post scores. Results : The average score for satisfaction was 3.06 out of 5.0; with relatively higher scores for sincerity (4.10) and professionalism (4.01) of the tutors, adequacy (3.54) and clearness (3.51) of the evaluation criteria, usefulness (3.54) and fitness (3.52) of the contents, but with relatively lower satisfaction for schedule (2.96) and self-studies (2.91). The average for requirement for education improved, as shown by the decrease from 2.72 to 2.22 (p<.0001) with the biggest decrease in the outbreak investigation from 2.60 to 2.08. Conclusion : The FESTP was evaluated as being effective, the trainees showed moderate satisfaction and decrease educational needs. However, the actual schedules and self-studies should be rearranged to improve the satisfaction level.

Purpose: The aim of this study was to evaluate the quality of the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency intensive care unit (ICU) in consultation with intervention radiologists and surgeons. Methods: This was a retrospective observational study conducted in an emergency ICU of a tertiary referral hospital. We enrolled consecutive patients who had been admitted to our emergency ICU with major trauma from March 2007 to September 2010. We collected data with respect to demographic findings, mechanisms of injury, the trauma and injury severity score (TRISS), emergency surgery, angiographic intervention, and 6-month mortality. Then, we compared the observed and predicted survivals of the patients. The Hosmer-Lemeshow test and calibration plots by using 10 groups, one for each decile, of predicted mortality were used to evaluate the fitness of TRISS. P-values of greater than 0.05 represent a fair calibration. Results: Among 116 patients, 12 (10.34%) were dead within 6 months after admission to the ICU, and 29 (25.00%) and 38 (32.80%) patients received emergency surgery and angiographic intervention, respectively. The mean injury severity score and revised trauma score were $36.97{\pm}17.73$ and $7.84{\pm}6.75$, respectively. The observed survival and the predicted survival of the TRISS were 89.66% (95% confidence interval [CI]: 84.03~95.28%) and 69.85% (95% CI: 63.80~75.91%), respectively. The calibration plots showed that the observed survival of our patients was consistently higher than the predicted survival of the TRISS ($p$ <0.001). Conclusion: The observed survival for the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency ICU in consultation with intervention radiologists and surgeons, was higher than the predicted survival of the TRISS.

Nowadays, the third-party logistics is getting special attention as one of the most useful ways to perform the logistics management effectively. In this current trend, however, there are many firms which carry out the logistics activities by themselves and strengthen the competitiveness. In respect of contingency theory, the firms' logistics management types should depend on their logistics environment and characteristics, and then the logistics performances vary with this suitability. In this context, this study analyzed empirically the difference of the logistics performances due to the fitness between their logistics characteristics and the management types. According to the finding, the study showed that the third-party logistics is more suitable when the importance and weight of logistics operation and the weight of their export are greater respectively, and the self-logistics is more suitable when the logistics cost is higher. Futhermore, the study indicated that the firms whose relationship between the characteristics and the management types is fit in their logistics are better than the others in the outcome of logistics cost reduction and the effectiveness of logistics operation.

The purpose of this study was to analyze the effects of name attractiveness on self-efficacy and emotional awareness in adult men and women. The subjects of this study were 300 males and females in their 10s and 30s living in the metropolitan area. However, 250 copies, excluding missing questionnaires during the collection process and incomplete questionnaires, were used for the analysis. As a result of analyzing the difference in name attractiveness according to factors, the lower the age group and the lower the academic level, the more dissatisfied they were with their names. Besides, the regression analysis conducted to verify the effect of name attractiveness on self-efficacy showed that the model's fitness was R²=.382 and the model's explanatory power was somewhat inferior, but β=.322, t-value 9.276, p<.001 were shown to be statistically significant, so name attraction directly affects self-efficacy. And the results of the regression analysis conducted to verify the effect of name attractiveness on emotionality turned out to be R²=.412. The regression analysis, which controls demographic variables such as gender, age, and academic level, was statistically significant as β=.326, t-value 6.408, p<.001. In other words, the name attractiveness affects emotional awareness. There is no empirical study that the name attractiveness can improve happiness or the quality of life, but it seems often among athletes that names are enhanced by the past.

This study intends to analyze the value of school forests, one type of urban forest. For this purpose, four attributes of school forests were investigated, considering ecological, educational, social and economic values using a conjoint model as the stated preference. Based on literature reviews, the levels of the four attributes were selected, and a questionnaire survey was given to 279 urban residents divided into 2 groups: those impacted by school forests and those not. The study results suggest that the most important attribute of school forests is economic value, and next is ecological, social and educational value according to the part-worth model. The fitness level of the model is 0.900(total group) which is very significant. As for the economic value, free and 1,000 won are more critical factors than the other 2 levels, 5,000 won and 10,000 won and air pollution purification and making the school landscape are more critical factors than small habitats and microclimate factors. In addition, regarding the social value related to residents' leisure activities，the utility of nature observation is higher than walking and exercising. Finally, for educational value, understanding nature's importance is more critical than the emotions and learning of students. The estimated WTP per household/month is 3,580 won, the group related to school forestsis 3,650 won and the non-related group is 3,540 won. Based on these results, the estimated total economic value of all households per year is 6,820 hundred million won. The group related to school forests is 6,970 hundred million won and the non-related group is 6,750 hundred million won.

This paper proposes a new design method of neuro-FLC by the Lamarckian co-adaptation scheme that incorporates the backpropagation learning into the GA evolution in an attempt to find optimal design parameters (fuzzy rule base and membership functions) of application-specific FLC. The design parameters are determined by evolution and learning in a way that the evolution performs the global search and makes inter-FLC parameter adjustments in order to obtain both the optimal rule base having high covering value and small number of useful fuzzy rules and the optimal membership functions having small approximation error and good control performance while the learning performs the local search and makes intra-FLC parameter adjustments by interacting each FLC with its environment. The proposed co-adaptive design method produces better approximation ability because it includes the backpropagation learning in every generation of GA evolution, shows better control performance because the used COG defuzzifier computes the crisp value accurately, and requires small workspace because the optimization procedure of fuzzy rule base and membership functions is performed concurrently by an integrated fitness function on the same fuzzy partition. Simulation results show that the Lamarckian co-adapted FLC produces the most superior one among the differently generated FLCs in all aspects such as the number of fuzzy rules, the approximation ability, and the control performance.
