This study utilizes the fuzzy logic and genetic algorithm to improve the existing incident detection models by addressing the problems associated with "crisp" thresholds and model transferability (applicability). The model's major components were designed to be a set of the fuzzy inference engines, and for the self-adaptation capability the genetic algorithm was introduced in optimization(or training) of the fuzzy membership functions. This approach is often called "the hybrid of fuzzy-genetic algorithm" The model performance was tested and found to be compatible with that of the existing well-recognized models in terms of performance measures such as detection rate, false alarm rate, and detection time. This study was not an effort for simple improvement of the model performance, but an experimental attempt to incorporate new characteristics essential for the incident detection model to be universally applicable for various roadway and traffic conditions. The study results prove that the initial objective of the study was satisfied, and suggest a direction that the future research work in this area must follow.

PURPOSES : The purpose of this study is to validate the design criteria of the concrete modular road system, which is a new semi-bridge-type concept road, through a comparison of numerical analysis results and actual loading test results under static axial loads. METHODS : To design the semi-bridge-type modular road, both the bridge design code and the concrete structural design code were adopted. The standard truck load (KL-510) was applied as the major traffic vehicle for the design loading condition. The dimension of the modular slab was designed in consideration of self-weight, axial load, environmental load, and combined loads, with ultimate limit state coefficients. The ANSYS APDL (2010) program was used for case studies of center and edge loading, and the analysis results were compared with the actual mock-up test results. RESULTS : A full-scale mock-up test was successfully conducted. The maximum longitudinal steel strains were measured as about 35 and 83.5 micro-strain (within elastic range) at center and edge loading locations, respectively, under a 100 kN dual-wheel loading condition by accelerating pavement tester. CONCLUSIONS : Based on the results of the comparison between the numerical analysis and the full-scale test, the maximum converted stress range at the edge location is 32~51% of the required standard flexural strength under the two times over-weight loading condition. In the case of edge loading, the maximum converted stresses from the Westergaard equation, the ANSYS APDL analysis, and the mock-up test are 1.95, 1.7, and 2.3 times of that of the center loading case, respectively. The primary reason for this difference is related to the assumption of the boundary conditions of the vertical connection between the slab module and the crossbeam module. Even though more research is required to fully define the boundary conditions, the proposed design criteria for the concrete modular road finally seems to be reasonable.

Although women's economic participation has been increasing in Korea, the utilization of educated women's labor is still low. Therefore, vocational training programs for women are both important and necessary. This study examines the vocational training programs for women offered by the three largest vocational training centers in Jeju: the Woman Resources Development Center, the Jeju Women's Development Center, and the Seogwipo City Women's Cultural Center. This study also analyzes the students' satisfaction with these vocational training programs and identifies the related variables that cause differences in their levels of satisfaction. The sample includes 397 respondents who were surveyed from June 23 to September 12, 2008. Moreover, the data are analyzed by conducting a one-way ANOVA, t-test, and Duncan's Multiple Range(DMR)test. The major results of the study are as follows. First, the vocational training programs in Jeju consist of lectures that cover various subjects. The programs mainly focus on work that offers relatively low wages and requires few skills, and the duration of the programs is short. Second, the original goal of the programs does not meet the needs of women who are seeking employment. The participants respond that they want more appropriate programs that are designed by considering their need for employment, support them in finding a job, and re-educate them. Third, most of the participants are satisfied with their vocational training experiences, and their satisfaction with the instructors is especially high. The differences in their levels of satisfaction are caused by economic characteristics such as the location of the student's residence, home ownership, and the level of life. The results of this study suggest that there is a need to separate vocational/employment training from general education for women. Moreover, the vocational training programs for women should be more specialized according to the different needs of each group.

Self-sufficiency ratio of food crops in Korea is estimated under $20{\%}$ in 2010 because total food consumption including feed will be increased. but food grain production will be decreased. It is necessary to maintain the optimum level of food self-sufficiency rate to secure national food demand/supply balance and non-trade and multiple function of agriculture in Korea. It will be possible to produce more food grains having the acceptable quality if the appropriate policy and cropping techniques are developed and practised in future. Breeding for high yielding varieties should be the first target to raise the production potential of food crops . Number of varieties developed during last 30 years is counted as 353 in food crops. New varieties developed in 1990s showed the higher yield potential and the improved agronomic characteristics compared with 1970s and 1980s varieties. But number of varieties planted on the farmer's field over $5{\%}$ of national planting area is less than one third of total varieties developed Breeding efforts to maintain planting area of main food crops should be focussed on consumer's demand and farmer's need. They are the best quality variety in each field of crop utilization, the newly designed variety adapting to changes of natural, rural and cropping environment, and the higher yielding variety. It is also needed to develop new quality crop varieties for inducing more consumption of crop grain produced in Korea for direct food or processing. Development of barley varieties for animal feed. high income soybean varieties, high quality wheat variety. and super yielding rice and barley varieties are also needed to keep or maximize national food production potential. In order to establish the appropriate cropping technique for domestic food security, the strong and continuous interest and financial support on crop breeding are required, and the inter-disciplinary and inter-institutionary researches should be strengthened for successful crop breeding.

For decades medical educators have continually emphasized medical professionalism, which is reflective response to the challenges of a rapidly changing medical environment. This study aimed to review the experience of implementing medical professionalism education at Yonsei University College of Medicine (YUCM). YUCM introduced a new curriculum in 2004 designed by Curriculum Development Project 2004 (CDP2004), a project that was launched in 2001. CDP2004 reorganized lectures as organ-based integrated lectures, introduced an introductory course for clinical medicine and medical humanities courses for premedical and medical students. Problem-based learning (PBL), elective courses, and self-study sessions in the afternoon were implemented in order to equip students with a self-directed learning attitude as medical professionals. Professors were asked by the CDP2004 curriculum to spend more time on student education and to adopt new teaching methods. Experiences of the CDP2004 curriculum reveals 1) difficulty of motivating professors to be PBL tutors 2) students' dissatisfaction with the medical humanities course (major critique was that the course was impractical and unrealistic), and 3) students' optimistic understanding about their future role as medical professionals in influencing and helping people in spite of their perception of the general medical environment not as promising. To foster professionalism, the following are necessary in our experiences: 1) faculty development of medical humanities and medical professionalism, 2) establishment of an environment throughout the whole institution to support medical professionalism education and to integrate the concept into praxis, 3) emphasis on the fact that medical professionalism education is not contradictory to biophysical medical education.

Background : Despite favorable effects of guidelines on patient care, guidelines often fail to achieve their objectives. Poorly implemented medical practice guidelines can produce only weak effects on the process of health care delivery. Therefore, we performed this study to investigate barriers related development of clinical practice guidelines. Methods : Cardiopulmonary resuscitation was selected as a target problem. Self questionnaires about management of cardiopulmonary resuscitation were developed by a researcher with advisory 8 experts. The questionnaires were designed as a unstructured methods. The data were collected from March 1 to May 31, 1999. A total 50 death case admitted inpatient to Inha University Hospital were subjected to evaluate the development and application of clinical practice guidelines for cardiopulmonary resuscitation. The data were examined by frequency, t-test with SPSS. Result : The article reviewed several common barriers that might limit successful implementation of guidelines in clinical practice, as illustrated by evaluating recommendations for cardiopulmonary resuscitation clinical practice guidelines. Some major problems with guidelines were characterized as follows (1) ethical problem : euthanasia, (2) occurrence on various emergency event and setting, (3) non-medical problems (4) unreliable of medical record etc. Conclusion : Careful analysis of guideline attributes, anticipated effect on medical care, and organizational factors revealed several barriers to successful guideline implementation that should be addressed in the design of future guideline-based interventions.

Most rail system related simulations currently used are designed to simulate only one discipline system. This obviously assunes the other discipline system are running regularly not being affected by the system being simulated. In this paper a multi discipline simulator is proposed and its design concept is presented.A multi discipline simulator is the simultor in which major subsystems with different technical discipline are simulated simultaneously. The advantage of the simulator is in that it makes it possible to analyze the systems behavior while other discipline system vary. With this we can identify the possible to analyze the systems ehavior find their solutions. A proto type simulator has bee developed using object oriented programming. Object concept was judged best suitable to model the various multi-discipline self-controlling railway subsystems. It was applied to the target system, which is under development by the Korea Railroad Research institute. The test results show it is very useful in design verification. It could also be a good tool in research and development work to make to improe the system.

The purpose of this study was to investigate the relationship of family resilience, gratitude, and child-rearing attitude and to identify predicting factors of family resilience among mothers of young children. A correlative research design was be used for this study with self-administered questionnaires. The subjects were 248 mothers of young children from kindergarten located in Jeonnam and Gwangju provinces in Korea. Data were collected between May to June, 2013. Descriptive statistics, Pearson's correlation coefficient, and multiple regressions with PASW Statistics 18 (SPSS 18.0) program were used for data analysis. The major findings are summarized as follows: (1) Family resilience was closely related to gratitude and four types of child-rearing attitudes. Gratitude was closely related to four types of child-rearing attitudes. And rejective attitude had significantly negative relations family resilience and gratitude. (2) The significant factors affecting family resilience were mother's education level, gratitude, affective attitude, rejective attitude, autonomous attitude and controlling attitude which explained 63% of the variance. The results indicate that gratitude and child-rearing attitude were significant factors associated with family resilience among mothers of young children. In order to increase the family resilience among mothers of young children, family programs that deal with both gratitude and child-rearing attitude should be designed.
