Objectives : We investigated the possibility of cervical spine misalignment caused by Scalenus anticus syndrome to find out the Scalenus anticus syndrome could effect misalignment of cervical spine. Methods : 18 patients with Scalenus anticus syndrome who attended Dept. of Oriental Rehabilitation Medicine, College of Oriental Medicine, Dong-guk University from 20th June to 10th September 2006, were involved in the investigation. After researching misalignment through neutrality lateral, flexion lateral, extension lateral x-ray examination views, we measured difference of length of cervical spine misalignment. We analyzed the difference of length of cervical spine misalignment, and the relationship among the neutrality lateral, flexion lateral and extension lateral position. Results : Lateral flexion and lateral extension position were shown higher frequency than neutrality position in cervical spine misalignment. We got the statistical significance in the difference of length of cervical spine misalignment by position changes, it showed that C3, C4 vertebra bodies in lateral neutrality position, C2, C3, C4, C5 vertebra bodies in flexion lateral position, C3-5 vertebra bodies in extension lateral position. Conclusions : It was considered that scalenus anticus syndrome could increase cervical spine misalignment which could be a factor of making in cervical spine disease.

강훈,박상희,이동훈 충북대학교 의과대학 충북대학교 의학연구소 2008 忠北醫大學術誌 Vol.18 No.1

Purpose: Acute pain can be abolished by intravenous administration of ketamine in doses insufficient to induce anesthesia. Therefore we designed this study to see if this subanesthetic dosage of ketamine administered epidurally with patient-controlled analgesia (PCA) after abdominal surgery can also provide sufficient analgesic effect on postoperative pain. Materials and Methods: 20 consecutive patients were allocated randomly to receive either ketamine (n=10) or placebo (n=10) for pain relief after surgery. At 30 minutes before the end of surgery patients were attached to an PCA infusor programmed to epidurally deliver same amount of placebo or ketamine 3-5 mg/h (72-120 mg/day) in combination with background PCA regimen composed of bupivacaine, morphine, fentanyl etc for 48 hours postoperatively. Patients were evaluated for pain on ten-point Verbal Analogue Scale (VAS) and nausea on a four-point scale at 30 minutes, and 1, 6, 12, 24 hours after surgery. Results: The pain score in the placebo group is not significantly higher than in ketamine group postoperatively. While the pain scores in the two groups were very similar, throughout the 24 hours period, the incidence of nausea/emesis was also similarly low in both groups. Conclusion: It was found that a fixed rate epidural infusions of ketamine (3-5 mg/h) are ineffective in controlling pain after surgery. 연구목적: 강력한 진통작용를 나타내는 케타민은 마취농도 이하의 용량을 정맥투여함으로써 수술 후 통증같은 급성 통증을 치료할 수 있다. 저자들은 이와 같은 마취농도 이하의 저용량을 경막외에 투여하는 경우도 급성통증에 비슷한 효과가 있는지 알아보고자 본 연구를 시행하였다. 대상 및 방법: 연구 대상 환자는 충북대학교병원 수술실에서 복부에 정규 외과 수술을 받은 후 48시간 이상 자가통증조절(Patient-Controlled Analgesia)을 이용하여 통증치료를 받은 성인 남녀 환자들이며 환자들은 무작위로 ketamine군(n=10)과 위약 대조군(placebo, n=10)의 두 군으로 나누고 수술 종료 30분 전에 미리 준비한 patient-controlled analgesia에 ketamine (3-5 mg/h) 혹은 placebo를 섞어서 투여하기 시작하였다. 수술 후 회복실 또는 병실에서 필요한 경우 급성통증을 예방하기 위하여 ketorolac 30 mg을 정맥 투여하였다. 환자의 통증과 부작용에 대한 평가는 회복실에서 그리고 수술 후 1, 6, 12, 24 시간에 시행하였다. 결과: 두 군 간에 인구학적 차이는 없었으며 수술 직 후 회복실에서 통증의 정도는 두 군 간에 유의한 차이가 없었으며 오심 및 구토 등의 부작용도 의미 있는 차이를 보여주지 않았다. 결론: 마취농도 이하의 저용량의 ketamine (3-5 mg/h)을 경막외에 투여하는 경우 의미있는 진통효과를 보여주지 못하였다.

LTCC적층형 대역통과필터의 공정 및 특성 최적화 연구

강동헌,차훈주 수원대학교 산업기술연구소 2003 산업기술연구소논문집 Vol.18 No.-

Multi-layered ceramic chip bandpass filter for 2.4 GHz ISM band was fabricated by using LTCC (Low Temperature Co-fired Ceramics) technology, and related processing parameters such as lamination condition, sintering temperature, time and electrode condition were investigated in terms of filters characteristics. The BPF consists of coupled stripline resonators and coupling capacitors. The sintering shrinkages was affected substantially by lamination pressure and sintering temperature. And insertion loss with inner conductor thickness has been discussed and realized. Insertion losses in the passband were less than 2 dB and the attenuation more than 25 dB at 2.1 GHz. The frequency response characteristics of the chip BPF is well acceptable for bluetooth application.

This study was aimed to suggest to better treatment method of jaw cyst that the maximum diameter was wider than 3cm, using different treatment and clinical and radiographic result. We divided the 60 patients into three groups, group A(20 patients) were treated with cyst enucleation and Decalcified Freeze-Dried Allogeneic Bone(DFDB) graft, group B(20 patients) were treated with cyst enucleation and autogenous bone graft, group C(20 patients) were treated with only cyst enucleation. Each group was evaluated with panramic radiograph and clinical sign & symptom at pre-op and post-op(immediate, 6, 12, 24, 36 month). Bone density was evaluated with disital densitometer. The result was as follows : 1. Post-Op infection was higher in group C(4 pts.) than in group A(1 pt.) and B(1 pt.) 2. Post-Op gingival recession was higher in group C(3 Pts.) than in group A(1 pt.) and B(1 pt.) 3. Anatomic distortion was higher in group C(3 Pt.) than in group A(1 Pt.), and B(1 pt.) 4. reoperation was done in two patients who were in group C 5. There were donor site morbidity in two patients 6. there was no significant difference between group A and B in their bony density in their follow up period(p>0.05). 7. There were significant differences between group A, B and group C in their bony density until post-op 24 months but a little differences at post-op 36 months(P<0.01)

The purpose of this study was to define teachers' learning motivation strategies and students' responses by analyzing science classes and interviews. The subjects were first grade and sixth grade teachers and students of an elementary school. The analysis tools are based on Keller's ARCS theory. The differences of teachers' motivation strategies were analyzed by grades and teachers' and students' backgrounds. The interviewers were composed of three teachers and three students of first grade, and three teachers and three students of sixth grade. The data were collected by recording of the classes using tape recorders, video cameras, and notebooks written by researchers. The results are as follows. First, teachers had their own styles of teaching strategies in their classes. Especially teachers' teaching backgrounds affected on the teachers' instructional strategies. The teachers who had long teaching experiences of lower grade students used to show a lot of attention strategies. While the teachers with long teaching experiences of higher grade students used to show few learning motivation strategies. Especially, sixth grade teachers used to show fewer confidence strategies than first grade teachers. Second, all of the teachers used to show few satisfaction strategies commonly in all the classes observed. Third, the students' recognition of the motivation strategies were not different according to their conceptions or activities of the classes. Commonly first grade students focused on the attention strategies, while sixth grade students focused on negative motivation strategies. Fourth, the teachers who believed that students need detail guidance and control recognized the needs of satisfaction strategies by students' autononmous activities after observing video tapes of other teachers' classes.

To determine the recovery time from noise-induced temporary threshold shift(TTS), a prospective field study was conducted at three worksites where workers are known to be exposed high level of noise. Subjects were selected according to answers on a questionnaire which inquired about otological history and previous noise exposure, including avocational, military and occupational exposures. After excluding employee with past otologic problems, recent exposure to high level noise, and under medications, total 92 employees participated in the study. Among 92 participants, complete consecutive audiometric examinations were carried out at 0∼2 hours, 5∼7 hours, 14∼16 hours after worktime noise exposure on 26 participants wearing hearing protectors and 22 participants wearing no protective devices. The difference between the hearing level 0∼2 hours after noise exposure and 5∼7 hours is statistically significant by paired t-test(p<0.01). The median recovery times calculated from the data of 22 participants wearing no protective hearing devices are 15.6 hours at 4000Hz, and 7.7 hours, 10.3 hours, 8.4 hours at 1000Hz, 2000Hz and 8000Hz respectively. These data suggest that when measuring the pure tone audiometry for noise exposed workers, at least 16 hours noise-free interval is required.
