Purpose : Our goals were to determine the frequency of headaches and backaches occurring as a side effect following lumbar puncture in children, and to investigate various factors that might influence the frequency of headaches and backaches. Methods : From October 2004 to February 2006, we enrolled 148 patients aged 2 to 15 years who received diagnostic lumbar puncture at the Presbyterian Medical Center, Chonju, Korea. Patient data were collected for age, sex, number of puncture attempts, volume of cerebrospinal fluid(CSF), bevel orientation of puncture needle, cell count in CSF, periods of absolute bed rest, and the frequency and duration of headaches and backaches. Results : Headaches occurred in 8 patients and backaches occurred in 40 patients. Headaches were found both to occur significantly more frequently in patients over age 10 and to last longer when the bevel orientation of the puncture needle was inserted toward the cranium rather than laterally. Backaches lasted longer in males than in females. The other factors evaluated showed no relationship at all to the frequency and duration of headaches and backaches. Conclusion : Following lumbar puncture, headaches were common in patients over age 10, and lasted longer when the bevel orientation was toward the cranium. Backaches lasted longer in males than in females. In light of these findings, we recommend taking special care when performing lumbar puncture for CSF examination in patients over age 10.

치아는 성별과 연령의 추정은 물론 혈형 검사와 유전자 검사까지 가능하게 하는 중요한 법의치과학적 자료이다 대부분 치아를 이용한 연구는 핵 DNA가 들어있는 치수에서의 연구로 치수내에는 풍부한 혈액 및 세포가 분포해 있어 핵 DNA가 다량 함유되어 있다. 그러나 순수 상아질에는 핵이 없고 따라서 핵 DNA도 없는 것으로 알려졌지만 치수내에 존재하는 핵 DNA가 상아세관을 통하여 상아질내로 침투할 가능성이 있고 실제 근관치료가 되어 있는 무수치를 감정하게 되는 경우도 있다. 본 연구에서는 이러한 치아중에서도 근관치료를 받은 무수치에서 개인식별에 활용되는 유전자가 검출되는지 여부를 확인하고자 하였다. 40개의 근관치료된 치아상아질에서 DNA출 추출하고 중합효소반응을 이용하여 증폭절편다형(Amp-FLPs)을 실시하고 X-Y homologous amelogenin gene과 STR 유전좌위 F13A01, LPL를 검색하여 다음과 같은 결과를 얻었다. 1. 40개의 근관치료된 치아중 19개에서 DNA가 추출되었다. 2. X-Y homologous amelogenin gene 검색으로 40개의 근관치료된 치아에서 21의 남자 치아중 5개, 19개의 여자치아중 7개 등 모두 12개 치아에서 성별검사가 가능하였다. 3. F13A01 유전자는 43개의 근관치료된 치아중 6개의 치아에서 검색되었으며, 4개의 대립유전자 및 5개의 유전자형을 관찰하였다. 4. LPL_유전자는 40개의 근관치료된 치아중 7개의 치아에서 검색되었으며, 3개의 대립유전자 및 3개의 유건자형을 관찰하였다. 이상의 결과를 종합하여 볼 때 근관치료된 치아상아질에서 중합효소반응을 이용한 성별검사 및 STR 유전자위의 검색은 일부 치아에서만 가능하였으나, 근관치료된 치아들도 개인식별을 위한 법의치과학적 자료로서 유용할 것으로 사료된다.

The purpose of this study is to investigate engineering students' attitude toward convergence and relevance with engineering education accreditation, gender, and academic year and attitude toward convergence. To be specific, fist, we examined whether the instrument for measuring attitudes toward convergence were reliable and valid for engineering students. Second, we compared levels of attitudes toward convergence in terms of engineering education accreditation, gender and academic year. Third, latent classes, which were distinguished in terms of attitudes toward convergence, were identified. Participants were 2076 engineering students. By using factor analysis and Rasch analysis, validity and reliability of instrument measuring attitudes toward convergence were confirmed. The differences in attitude toward convergence in terms of engineering education accreditation experience, gender, and academic year were examined by independent t-test and ANOVA. There were significant differences in attitude towards convergence in terms of engineering education accreditation, gender, and academic year. Students who experience engineering education accreditation program and male and high academic year have higher levels of attitude toward convergence than others. Lastly latent class analysis (LCA) was conducted to identify subgroups underlying engineering students in terms of attitude toward convergence and five latent classes were identified. In addition, the chi-square results showed that there were significant relationships between identified latent classes and engineering education accreditation, gender, and academic year. Based on these results, engineering education considering students' characteristics and diversity in attitude toward convergence were discussed.

The purpose of the study was to investigate the gender differences of anaerobic capabilities between anaerobic capacity(AC) from Wingate test and anaerobic work capacity(AWC) from critical power test in untrained male and female adults. Both tests were carried out to 12 male and 13 female subjects on a Monark cycle ergometer. The results of this study demonstrated that men were higher than women in AC for the Wingate test, but no gender difference(J/kg) in AWC for the Critical Power test. There was a significant relationship between AC(J/kg) and AWC(J/kg) in women(r=0.61, p<0.05), but no significant relationship in men(r=-0.32, p>0.05). ANCOVA analyses using $VO_{2max}$ and body weight as covariates had significant influence on the AWC gender difference. The study provides preliminary data on gender differences of anaerobic capabilities.

Thyroid nodules are an endocrine disease often found in clinical practice, and patients with thyroid nodules found by chance have rapidly increased alongside development of thyroid ultrasound techniques for health examination purposes. This study analyzes the subjects' general characteristics, thyroid ultrasounds, and fine needle aspiration cytology in order to find out the relationship between male and female thyroid nodules and thyroid cancer frequency. An ultrasound examination of the thyroid was performed for 32,973 individuals who visited the K Hospital of Health Examination. Subjects have no history of thyroid disease and are 20 years old or over. Data of general characteristics, diabetes) was collected by a written survey completed by the subject, and the ultrasound of the thyroid(thyroid nodules existence, size, number) and FNAC was used to find out the malignancy rate. Frequency of patients with thyroid nodule was 4,611(26.1%) in men and 5,341(34.9%) in women between 32,973 individuals. Women's prevalence rate is significantly higher than men, and the prevalence rate significantly increased with age in men and women(p < 0.05). The prevalence of multiple nodules was significantly higher in women(43.5%) than in men(35.6%), and significantly increased with age in men and women(p < 0.05). The fine needle aspiration cytology was performed in 692(men 342, women 350) subjects who showed signs of malignancy through ultrasound. Prevalence of malignancy of the nodules was higher in men(33.3%) than in women(29.4%) although it is not statistically significant. It is known that thyroid nodule prevalence in women is much higher than in men. But this study shows the men's prevalence rate was not too low compared with women, and the men showed a rather higher malignancy rate in nodules than women. It is considered that the role of thyroid ultrasound is both important in men and women.
