  • The purpose of this study was to examine the satisfaction level of dental hygiene students with the general education courses of the dental hygiene curriculums and their awareness of the curriculums in a bid to seek ways of improving the general education curriculums. The subjects in this study were 265 sophomores in four different colleges located in the cities of S, L and K. A self-administered survey was carried out, and the findings of the study were as follows: In terms of satisfaction level with the general education courses, they got 2.54, which was a low score. To be specific, they expressed the most satisfaction with the duplication of the courses (2.63%), followed by appropriateness (2.61%) and teaching methods (2.60%). As for links between general characteristics and satisfaction with the general education courses, the students who were more satisfied with their major were more gratified with the general education courses, and the gap between them and the others was statistically significant (p<.001). The students didn't think that the general education courses they were taking were conducive to character building. Concerning connections between general characteristics and view of the general education courses, the students who were better contented with their major took a more favorable view of the general education courses, and the gap between them and the others was statistically significant (p<.05). In relation to expectations for the general education courses, they asked for efficient teaching methods, competent lecturers and the kinds of general education courses that could step up self-development. Therefore the general education curriculums should discreetly be reviewed to ensure the successful and diverse implementation of the curriculums.

  • The purpose of this study is to find out the difference in circadian rhythm and level of fatigue between ER and General Ward Nurse. This study was done through analyzing body temperature, heart rate and major electrolytes such as $Na^+$ and $K^+$ concentration on urinalysis, which are related to factors of circadian rhythm and level of fatigue. The subjects, 17 nurses from Emergency Room and 25 nurses from general ward, were selected from a General Hospital in Taegu City on August 8 to 23, 1998. And the data were analyzed by proportion, t-test, chi-square and Pearson's Correlation, ANCOVA, using SAS program. The results of this study were shown as follows: First, The difference of Maximal and minimal heart rate was significant between ER group and general ward group. However, body temperature difference wasn't notable. Second, Urine $Na^+$ concentration on urinalysis was lower and $K^+$ concentration on urinalysis was higher in ER group than general ward group significantly. Third, Fatigue level was higher in ER group than general ward group significantly. Fourth, through urine concentration, significant relations in circadian rhythm of ER nurse group and general ward group and their fatigue level were found. Urine $Na^+$ concentration on urinalysis of ER nurse was significant related with their fatigue level. In conclusion, the effect of fatigue on circadian rhythm is greater in ER group than general ward group during night shift. This study could be a help in improvement of nurse's health and understanding the effect of fatigue on health.

  • Background: Despite the majority of papillary thyroid microcarcinoma (PTMC) patients having an excellent prognosis, cervical lymph node metastases are common. The purpose of this study was to investigate the incidence and the predictive risk factors for occult central compartment lymph node metastasis (CLNM) in PTMC patients. Materials and Methods: 178 patients with clinically node-negative (cN0) PTMC undergoing prophylactic central compartment neck dissection in our hospital from January 2008 to Jun 2010 were enrolled. The relationship between CLNM and the clinical and pathological factors such as gender, age, tumor size, tumor number, tumor location, extracapsular spread (ECS), and coexistance of chronic lymphocytic thyroiditis was analyzed. Results: Occult CLNM was observed in 41% (73/178) of PTMC patients. Multivariate analysis showed that male gender, tumor size (${\geq}6mm$) and ECS were independent variables predictive of CLNM in PTMC patients. Conclusions: Male gender, tumor size (${\geq}6mm$) and ECS were risk factors of CLNM. We recommend a prophylactic central lymph node dissection (CLND) should be considered in PTMC patients with such risk factors.

  • The goals of this study were to investigate depression and oral health-related quality of life in the military and public and to identify the factors affecting depression. The respondents were 278 soldiers and 228 general people of similar ages. An independent t-test was used to examine the differences between the two groups in the oral health impact profile and Self-rating Depression Scale. A multivariate logistic regression analysis was performed to examine the factors associated with depression in soldiers and the public. The depression level was significantly higher in the general population than in the military personnel (p<0.001). In contrast, the oral health-related quality of life was better in the general population than in the military, but without a statistical significance (p=0.056). Among soldiers, the military rank was the only factor associated with depression, showing a gradient based on the rank. In the general population, the type of work displayed significant associations with depression. As there are some limitations to investigating the factors affecting depression, comparative analyses of the general population groups with similar soldier groups are rare. This study encourages future investigations of the advancements in mental health and improvement programs for oral health in each group.

  • Purpose: The purpose of this study was to investigate the extent and the nature of biological nursing science education for clinical nurses in general hospital. Methods: Five advanced general hospitals located in Seoul and Gyeonggi province were conveniently sampled. Contents of education for nurses conducted by the hospital nursing department from January 1 to December 31 of 2015 were collected. Contents of education included biological nursing science and the scope of inclusion and time of assignment were analyzed. Results: A total of 271 cases of nursing education data were collected and 223 cases were analyzed after excluding 48 cases whose contents were not confirmed. Biological nursing science was included in the contents of education for 117 cases (52.5%), but not for 106 cases (47.5%). Regarding the frequency of the biological nursing science education contents, 'pathophysiology'was the most frequently included (n= 286), followed by 'structure and function of the human body' (n= 191), 'mechanisms and effects of drugs' (n= 114) and 'clinical microbiology' (n= 43). Conclusion: Results of this study confirmed that the education for clinical nurses included a lot of biological nursing science related contents. These results can be used as basis for the development of curriculum and training course for nurses.

  • The educational policy of a nation should be based on the results of nation-wide studies and their analyses. This study is the third one in a series of research on "development of improvement plan and monitoring system for secondary school science", focusing on the three major areas, such as students' achievements, science instruction and conditions for science education in vocational high schools. In general, the results showed that science achievements in vocational high schools were significantly lower than those of general high schools. While the achievement level in physics was lower by one percent, the achievement levels in chemistry and biology were significantly lower by more than 5 percents. In the case of scientific inquiry, the results showed much lower scores compared to those of general high schools. Concerning the inquiry abilities, most of the students did not possess the formal operational thinking skills such as controlling variables and combinatorial thinking. The ability of experimental skills seemed to be closely related to the students' majors. Students in industrial arts schools could measure electric resistance very well, while students in agricultural high school students failed completely. In the area of students' attitude toward science, the greater part of the students had the experiences of using scientific equipments (68.6 %), experimentation (54.3 %), and extracurricular science activities (56.9 %). They also showed positive attitude towards the nature of science (59.8%). The results of the survey on science instruction and school conditions for science education showed the needs for improvement In general, the priority of science education in vocational high schools was very low compared to their major subjects. The teachers as well as students thought science text books nor to be difficult These responses and the low achievement levels seemed to be contradictory to each other. The facilities for science experiments were better equipped and installed to general high schools. However. the lack of budget was a major problem for performing experiments uning the facilities. Therefore. science education in vocational high school have many things to be improved For the improvement of science education in vocational high schools, financial support as well as the intention for the improvement must be the essential factors.

  • In this paper, we study a class of Finsler metrics called general (${\alpha},{\beta}$)-metrics, which are defined by a Riemannian metric ${\alpha}$ and a 1-form ${\beta}$. We show that every general (${\alpha},{\beta}$)-metric with isotropic Berwald curvature is either a Berwald metric or a Randers metric. Moreover, a lot of new isotropic Berwald general (${\alpha},{\beta}$)-metrics are constructed explicitly.

  • General (${\alpha},{\beta}$)-metrics form a rich class of Finsler metrics. They include many important Finsler metrics, such as Randers metrics, square metrics and spherically symmetric metrics. In this paper, we find equations which are necessary and sufficient conditions for such Finsler metric to be locally projectively flat. By solving these equations, we obtain all of locally projectively flat general (${\alpha},{\beta}$)-metrics under certain condition. Finally, we manufacture explicitly new locally projectively flat Finsler metrics.
