To clarify the therapeutic effect of aquapuncture therapy on bovine foot rot, the experimental cattle were divided into control (conventional treatment), aquapuncture and combined treatment groups. Each group was composed of 6 Holstein cows with bovine foot rot. In the present study, the change in grade of lameness, total leukocyte counts, N/L. ratio, mean recovery rates (days) and histopathological changes of interdigital tissue before and after treatment were evaluated. The grade of lameness was decreased by treatment in each group, with the decreasing in order of combined > aquapuncture > control group. In change of total peripheral blood leukocyte counts, the tendency of decrease was found. Significances were detected on 9th day (P < 0.05) in control, on 6th day (P < 0.01) in aquapuncture group, and on 3rd (P < 0.05) and 6th day (P < 0.05) in combined group, respectively. In addition, significances were detected on 3rd and 6th day in aquapuncture, and on 3rd day in combined group by comparison with that of control, respectively. N/L ratio was decreased by therapy in each group with the decreasing in order of combined > aquapuncture ) control group. Significances were detected on 6th day (P < 0.01) between aquapuncture and combined groups. The mean recovery rates(days) were rapid with the decreasing in order of combined > acuapuncture > control group. In histopathological findings of interdigital tissue, the findings of inflammation and hemorrhage were not observed after treatment in each group. In conclusion, it was thought that aquapuncture and combined therapy was very effective on treatment of bovine foot rot.

Aims: The study aimed to compare treatment compliance and nutritional outcomes in nasopharyngeal carcinoma (NPC) patients during chemoradiation. Methods: Clinical information of patients with NPC that underwent chemoradiation during 2004-2009 were retrieved from the hospital database and retrospectively reviewed. Patients were categorised into a prophylactic percutaneous endoscopic gastrostomy (PPEG) group and a non-PPEG group. Clinical information including treatment compliance, weight, haematological and renal toxicity was compared. Results: A total of 219 patients were reviewed and categorised into PPEG (n=77) and non-PPEG (n=142). Significant differences in absolute percentage weight loss between groups were found from the $3^{rd}$ cycle of chemotherapy. There were 24.2, 20.3 and 24.8% in the third, the fourth and the fifth cycles of chemotherapy, respectively. Migration of grade 2 to grade 3 weight loss was obviously seen in the $3^{rd}$ cycle as well. A significant difference of grade 3 or more hypokalemia was found with values of 14.3% and 50% in the PPEG and non-PPEG groups, respectively. Other toxicity parameters and treatment compliance were not different between the groups. Conclusions: Use of PPEG resulted in decreased severe weight loss, reduced migration from grade 2 to grade 3 weight loss and reduced hypokalaemia. However, benefits in treatment compliance could not be detected. So consideration of PPEG in NPC patients requires care.

While internet and cellular phones are very attractive to adolescents, they cause a lot of problems because of adolescent's addiction to internet and cellular phones. The purpose of this study is to investigate relations among overuse of internet and cellular phone and academic achievement with middle school students according to their sex and grade. For this purpose, the survey consist of 44-item, self-administered paper-and-pencil questionnaire from 444 two middle schools students located in Busan. Also, their academic achievements were used for statistical data processing. As a result, firstly, middle school students did not tend to be so seriously addicted to the internet and cellular phones. The internet was used more by male students and cellular phones by female students, and the more male and female students used the internet, the higher they tended to use the cellular phones. There was a negative correlation between the tendency of internet use and academic achievement, but there were no significant differences between genders. In terms of the tendency of using cellular phones and academic achievement, there were no correlations among male students, but there was a negative correlation in female counterparts. Secondly, in terms of grade, the 2nd-grade students had a higher tendency to use both of them than the 1st- and 3rd-grade counterparts. The tendency of using the internet and cellular phones, in each grade had significantly static correlation and the higher they tended to use the internet, the lower they had academic achievement the 3rd-grade. On the other hand, the tendency of using cellular phones, only 2nd-grade students had low academic achievement.

The subjects were 3rd grade elementary school students in Ulsan area (total 1,349; 734 males and 615 females). The skipping breakfast group were 215 students, 15.4% of total subjects. Major reasons for skipping breakfast were 'have no time' 27.8%, 'no appetite' 26.9%, 'over sleeping' 14.9%. Females and eating breakfast group had better dietary habits than males and skipping breakfast group. The scores of nutrition knowledge of females were higher than those of males. The dietary behaviors scores of eating breakfast group were higher than those of skipping the breakfast categories. Our results showed that these difference by sex and skipping breakfast in dietary habits, nutrition knowledges, dietary behaviors should be considered in developing of nutrition education program for low-grade elementary school students.

In this study, the researchers analyzed the 2015 revised 3rd~6th grade Korean mathematics textbooks from the aspects of social justice in mathematics education. For this study, the researchers constructed a textbook analysis framework for social justice subjects, which categorized by social issues, economy education, democratic education, personality education, safety education, environmental education, and career education. As a result, the 2015 revised elementary mathematics textbooks were reflected the subject matter of social justice in the order of social issues, economic education and democratic education, personality education and environmental education, safety education and career education. Also, the subject of social justice appears in all 3rd~6th grade mathematics textbooks, but it is not explicitly dealt with by combining it with mathematical content. The researchers suggested that mathematics lessons should be developed including social justice issues aligned with elementary mathematics contents.

The purpose of this study is to examine how well students can acquire scientific knowledge from the process and activity presented in the textbook. This is achieved by analysing of comparison on the material area in the 6th and 7th national curriculums' 3rd and 4th grade science textbooks. The method of this study is to analyse the contents, teacher's instruction and illustrations of the textbooks in the material area in both 6th and 7th national curriculum's 3rd and 4th grade science textbooks. Following is the result of the study. First, compared to the 6th national curriculum's content. 7th national curriculum is composed by phenomenon and activity focused. This considers student's developmental stages and abilities of concentration so one topic in the textbook is divided into 16 small contents. Therefore the textbook content of the 7th curriculum seems to have desirable changes. Secondly, teacher's instruction in the textbook of the 7th curriculum has impartial distribution in part Ⅰ and part Ⅱ according to Homey's analysis. This shows that some problems of writing textbooks that were pointed in the 6th curriculum have been improved. Thirdly, the content of the textbook emphasizes inquiry process as the 6th curriculum did. The 7th curriculum, however, more deeply deals with expecting and inferring. Finally, the analysis of illustration shows that the proportion of motive induction is high. This is also desirable approach to give students more interests in studying science.

Objective : Cerebral vasospasm is a common and potentially devastating complication of aneurysmal subarachnoid hemorrhage (aSAH). Inflammatory processes seem to play a major role in the pathogenesis of vasospasm. C-reactive protein (CRP) constitutes a highly sensitive inflammatory marker. Elevation of serum CRP levels has been demonstrated in patients with aSAH. The purpose of the current study was to evaluate the possible relationship between CRP levels in the serum and transcranial Doppler (TCD) and the development of vasospasm in patients with aSAH. Methods : A total of 61 adult patients in whom aSAH was diagnosed were included in the study from November 2008 to May 2011. The patients' demographics, Hunt and Hess grade, Fisher grade, CT scans, digital subtraction angiography studies, and daily neurological examinations were recorded. Serial serum CRP measurements were obtained on days 1, 3, 5, 7, 9, 11 and 13 and TCD was measured on days 3, 5, 7, 9, 11 and 13. All patients underwent either surgical or endovascular treatment within 24 hours of their hemorrhagic attacks. Results : Serum CRP levels peaked on the 3rd postoperative day. There were significant differences between the vasospasm group and the non-vasospasm group on the 1st, 3rd and 5th day. There were significant differences between the vasospasm group and the non-vasospasm group on the 3rd day in the mean middle cerebral artery velocities on TCD. Conclusion : Patients with high levels of CRP on the 1st postoperative day and high velocity of mean TCD on the 3rd postoperative day may require closer observation to monitor for the development of vasospasm.
