Purpose: The aim of this study is to present the basic data for qualitative improvement of emergency care for emergency patient by paramedic in fire station by understanding the level of awareness and practice in prehospital and transfer step, and understanding the level of emergency care and improvement of clinical knowledge through hospital clinical training. Methods: The researchers explained the objective for 143 persons who completed hospital clinical training from June 2nd, 2006 to October 23rd, 2009 among paramedic in fire station. The questionnaire in this research consisted of 80 questions. In the reliability for the awareness of emergency patient assessment, cronbach's $\alpha$ was 0.95, and in the reliability for emergency care fulfillment, cronbach's $\alpha$ was 0.93. reliability for clinical knowledge improvement is cronbach's $\alpha=.95$, and reliability for emergency care fulfillment is cronbach's $\alpha=.82$. Collected data was analyzed through SPSS 18.0 statistics program for frequency, percentage, average, standard deviation, Paired t-test, t-test, Correlation Coefficient, and internal consistency reliability was analyzed by cronbach's $\alpha$. Results: 1) The paramedic awareness and practice difference for emergency patient is statistically signification for general patient assessment(t=14.159, p=.000), trauma patient assessment(t=11.288, p=.000), internal medicine patient assessment(t=10.898, p=.000), and it shows the level of practice is lower than the level of awareness. 2) The paramedic difference between the level of awareness and practice according to whether or not they have clinical career is not signification on awareness(t=3.119, p=.125), and is high on practice(t=3.119, p=.002). 3) The correlation between paramedic awareness and the level of practice shows positive correlation(r=.61, p=.000). The higher the awareness of emergency patient assessment is, the higher the level of practice is. 4) The difference between paramedic clinical knowledge improvement and the level of emergency care practice is statistically significant(t=3.351, p=.001). 5) 89.6%(128 persons) of paramedic replied hospital clinical training experiences are helpful for field activity. 92.3%(133 persons) replied they apply well for clinical knowledge learned during hospital clinical training and emergency care skills in the field. Conclusion: Paramedic in fire station must evaluate the patient's initial assessment and activate the transfer system to the emergency department. It is necessary to develop and implement the effective education program continuously. The education program should systemize currently operated hospital clinical training. emergency disease and symptoms emergency care method, and practice mainly skill education should be progressed. In the prehospital and transfer management, high quality of medical assessment is required to the emergency medical service system. Medical direction from the doctors can feedback the paramedic continuously and continuing education must be provided to the paramedic in fire station.

Purpose: The aim of the study was to assess and identify gender differences in factors associated with prevalence, awareness, and treatment of osteoporosis. Methods: Data for 3,071 men and 3,635 women ($age{\qeq}50$) from the Korea National Health and Nutrition Examination Survey 2008~2011 were included. Osteoporosis was defined by World Health Organization T-score criteria. Impact factors and odds ratios were analysed by gender using multivariate logistic regression. Results: Osteoporosis prevalence rates were 7.0% in men and 40.1% in women. Osteopenia rates were 45.5% and 46.0% respectively. Among respondents with osteoporosis, 7.6% men and 37.8% women were aware of their diagnosis. Also 5.7% men with osteoporosis and 22.8% women were treated. Higher prevalence was found among respondents who were older, at lower socioeconomic levels, with lower body mass index and shorter height in both genders, and among women with fracture history, and non-hormonal replacement therapy. Awareness and treatment rates for the risk groups were similar compared to the low risk controls for both genders. Fracture history increased awareness and treatment rates independently for both genders. Women with perceived poor health status and health screening had increased awareness and treatment rates, but not men. Conclusion: Results indicate that postmenopausal women have a higher prevalence of osteoporosis than men and awareness and treatment rates were higher than for men. Despite gender difference in prevalence, osteoporosis was underdiagnosed and undertreated for both genders. Specialized public education and routine health screenings according to gender could be effective strategies to increase osteoporosis awareness and treatment.

This study examined differences in body mass index (BMI), self-esteem, sociocultural attitude toward appearance, and diet awareness between genders as well as the effect of BMI, self-esteem, and sociocultural attitude toward appearance on diet awareness. This study surveyed adults between the ages of 20 and 29 who lived in Daegu and Uijeongbu from November $17^{th}$ to December $14^{th}$ 2014. Data collected from 258 respondents were analyzed using descriptive statistics, t-test, regression analysis, and ${\chi}^2$ test. The study results showed that the respondents could be divided into three groups (underweight group, standard weight group, and overweight group) by BMI and a large percentage of respondents were in the standard weight group. The percentage of standard weight females was higher than standard weight males. There were significant differences in BMI, sociocultural attitude toward appearance (such as self-awareness), and diet awareness between genders; however, there was no difference in self-esteem. Men also had a higher BMI than women; however, women were more self-aware of sociocultural standards for appearance, desired a slim body and wanted educational information on diet. BMI and sociocultural attitude toward appearance had positive effects on diet awareness. Self-awareness was a strong predictor of diet awareness and self-esteem had no significant effect on diet awareness.

This study conducted a comparative analysis of awareness level of review standards, continuing education, and awareness about the need for speciality and educational courses in order to improve quality of Korean health insurance review work and to present directions for policies of personnel development and continuing education to smoothly perform hospital's insurance claim work and Agency's review work. The analysis unit of the study is individuals, and survey was conducted among hospital's claim officers and Agency' review officers by distributing questionnaires. The major results of the study are as follows: First, it is found that hospital's claim officers and Agency's review officers have conflicting awareness about review standards; more Agency's review officers think that current review standards are universal and reasonable, while more hospital's claim officers believe that they need to be revised. Especially, hospital's claim officers replied that it is possible that review results can differ according to government's policies. Second, there is no significant difference between the two groups in the opinion that there are individual differences in awareness level of review standard. In particular, both groups share the opinion that review results can differ according to officer's interpretation of review standards. Third, Both review officer groups feel the need for further training and continuing education. Fourth, there is no difference between the two groups in the opinion that both groups members should be educated in review related educational institutions. However, while 81.5% of Agency's review officers the education should be offered at the Agency, only 45.2% of hospital's claim officers agreed to it. Fifth, both review personnel do not show any difference in awareness of needed experience to successfully perform review work; both groups replied that three to four years experience is necessary to smoothly perform claim work and review work. This study was tried in order to search for directions to improve Korean insurance review work in quality rather than to explore characteristics themselves of individual factors. In this sense, this study presupposed an intention that the educational subjects for further training and continuing education for the two groups should be the same in order to narrow the awareness gap between hospital's claim officers and Agency's review officers. Thus, this study suggests that it is desirable to offer beginner courses at junior colleges or in undergraduate courses and advanced courses in professional graduate school for six to twelve months. In that a comparison of awareness level of hospital's claim officers and Agency's review officers who are actually in practice should precede appropriate presentation of directions for the qualitative improvement of insurance review work in Korea, the significance of this study lies in comparatively analyzing the awareness level of hospital's claim officers and Agency's review officers and in presenting the establishment of future further training and continuing education.

This study investigated whether there are differences between Korean-English bilingual and Korean monolingual children on phonological awareness skills. Participants were 11 Korean-English bilingual children and 12 Korean monolingual children. The children's ages ranged between 6 and 7 years. The results were as follows. First, the bilingual children significantly outperformed monolingual children on overall phonological awareness tasks. The bilinguals performed significantly higher than monolinguals on all three types of phonological awareness tasks (segmentation, deletion, and blending). Second, there was a significant difference between the groups with respect to phonological units of the tasks. The bilinguals performed significantly better than monolinguals on the phonemic unit tasks, but two groups did not differ significantly on syllabic unit tasks. There was an interaction effect between unit size(syllables and phonemes) and group (bilinguals and monolinguals). Third, there were correlations for both bilingual and monolingual children between overall phonological awareness skills and word recognition skills.
