This study developed hair stream-based haircutting techniques and investigated the level of consumers’ satisfaction with them. Then, the study results found the followings: First, divide the head into triangular sections according to the direction of hair stream under the principle of celestial sphere based on the median and temporal lines, focusing on the G·P of the hair stream in three levels(X, Y and Z) without tensioning in a direction toward the parallel of latitude. Second, after dividing each section in a direction toward the line of longitude, it is parted into more than one triangle. Third, the hair in each parting is divided along the direction of hair stream. Fourth, based on the hair line around the ears, the length and design of haircut are determined. Depending on the division of hair stream, hair is cut using the moving design line method. For the objective classification of hair-stream haircut, customers’ satisfaction with hair-stream haircut was analyzed. As a result, a very high satisfaction level(4.92 scores) was observed. The mean was pretty same by age without significant difference: 4.97 in a group of age 40s or below; 4.86 in a group of age 50s; 4.94 in a group of age 60s or older. In terms of the mean frequency of haircut as well, no big difference was found: 4.91 in one month or below; 4.92 in at least two months. As the frequency of hair-stream haircut increased, in addition, customers’ satisfaction with hair-stream haircut was high. In addition, they showed a strong intention to have a hair-stream haircut again or recommend it to others. Moreover, as their satisfaction with hair-stream haircut increased, they were more willing to have a hair-stream haircut again and recommend it to others. Considering the results above, compared to conventional haircut techniques, hair stream-based haircut is simpler and looks more natural and lighter. Therefore, it is perceived as a new haircut technique. Because it is still very new to many hairdressers, however, it should be continuously taught to them.

The electronic property of graphene was investigated by hydrazine treatment. Hydrazine (N2H4) highly increases electron concentrations and up-shifts Fermi level of graphene based on significant shift of Dirac point to the negative gate voltage. We have observed contact resistance and channel length dependent mobility of graphene in the back-gated device after hydrazine monohydrate treatment and continuously monitored electrical characteristics under Nitrogen or air exposure. The contact resistance increases with hydrazine-treated and subsequent Nitrogen-exposed devices and reduces down in successive Air-exposed device to the similar level of pristine one. The channel conductance curve as a function of gate voltage in hole conduction regime keeps analogous value and shape even after Nitrogen/Air exposure specially whereas, in electron conduction regime change rate of conductance along with the level of conductance with gate voltage are decreased. Hydrazine could be utielized as the highly effective donor without degradation of mobility but the stability issue to be solved for future application.

The anatomy of the human epidural space was demonstrated in 8 patients by computed tomography (CT) examinations performed after epidural injection of water soluble radiographic contrast material into the L3-4 epidural space via Tuohy needle. The examinations showed the posterior epidural space to be divided by the plica mediana dorsalis and an additional transverse connective tissue plane. The compartmentalized nature of the space may be, at times, responsible for entrapment and coiling of epidural catheters, despite the satisfactory technical performance of catheterization for epidural anesthesia. All patients demonstrated a great amount of fatty tissue within the junction of the posterior midline epidural connective tissue structures, producing a triangular-shaped structure which might be an impediment to catheterization. The posterior epidural space is more easily filled with contrast media than the anterior epidural space. We also measured the depth of epidural space. The posterior epidural space was 2-6 mm deeper than the anterior epidural space. At the thoracic spine, the depth of the posterior epidural space was about 1-2 mm and the anterior space was under 1 mm or revealed trace. At the lumbar region, the depth of the posterior epidural space was about 4-7 mm. Air bubbles were noticed in the epidural space, especially around intervertebral foramen; therefore, it was suggested that the air bubbles can produce incomplete analgesia along the nerve roots.

It is a known fact that the increase of intraocular pressure results from the action of succinylcholine, endotracheal stimulation to carina, bucking and coughing etc during the induction arid recovery periods. Efforts have been made by several inveatigators to prevent intraocular hypertension by giving trimetaphan, inderal or curare. However, their effects were not remarkable. In this study, lidocaine 1mg/kg was administered intravenously to selected patients 2-3 minutes before induction ; followed by regular induction with pentothal, succinylcholine and intubation. Intraocular pressures were measured at the pre-induction and post-intutation time, and every 30 minutes until the early recovery period, thereafter. The result of this study showed that the post-intubational increase of intraocular pressure was prevented in 86.7% of the lidocaine pretreated cases. The increase of post-extuba-tional intraocular pressure was also reduced significantly in the lidocaine pretreated group as well. We came to the conclusion that lidocaine pretreatment technic can be used effectively to prevent intraocular hypertension caused by induction and extubation in clinical practice.

목적: 본 연구는 임신 시 비정상 자궁경부 세포진 검사의 임상적 중요성과 이들의 추적 관찰을 위한 세포진 검사와 질확대경검사의 효용성을 평가하기 위해 시행되었다. 방법: 2002년 1월부터 2007년 12월까지 ASCUS 이상의 비정상 자궁경부 세포진 검사의 결과로 질확대경 클리닉에 전원되어진 임산부들을 후향적으로 분석하였다. 첫 질확대경검사는 임신 제 1 삼분기 말에 시행되었다. 남은 임신 기간 동안 1~2회 그리고 산후 6~8주에 자궁경부 세포진 검사와 질확대경검사가 반복 시행되었다. 질확대경검사상 이상소견을 보이면 질확대경하 조준 생검이 시행되었다. 침윤의 증거가 없다면 임신 중에는 어떠한 침습적 시술도 시행치 않았고 지속적 CIN2 이상의 병변은 산후에 치료되었다. 산후 진단 결과를 최종 산전진단명 및 초기 세포학적 진단과 비교하였다. 결과: 5년 동안 103명의 임산부가 질확대경검사 클리닉에 의뢰되었다. 산전에 침윤성 자궁경부암은 보이지 않았다. 53명의 환자가 산후 확진을 위해 추적 관찰되었고 이중 CIN2이상의 병변을 가지는 17명의 환자가 치료되었다. 2례의 미세침윤성 펀평상피세포암, 1예의 침윤성 샘상피암이 산후에 진단되었다. 처음 세포학적 진단상 ASCUS 소견을 보인 33명군에서는 7례의 CIN2, 3 병변과 3례의 침윤성 암이 진단되었다. 11 LSIL군에서는 1례의 CIN3 병변을 보인 반면 모든 HSIL 환자는 CIN3 병변을 보였다. 임신 중 CIN2, 3로 진단되어진 16명에서는 산후 2례의 미세침윤성 편평상피세포암이 진단되었다. 결론: 임신 시 자궁경부 세포진 검사장 ASCUS 소견을 보인 환자는CIN2, 3 그리고 암으로의 진행 가능성이 30%이다. LSIL은 85%에서 정상소견을 보였고 HSIL군은 100% CIN3였다. 산전 CIN2, 3가 미세침윤성 편평상피세포암으로 진행될 위험성은 12.5% 이나 조준 생검상 침윤 소견이 보이지 않으면 세포학적 검사와 질확대경 검사에 의한 추적 관찰 그리고 보전적인 관리는 합리적인 치료 방법이다. Purpose: This study was performed to evaluate the clinical significance of abnormal cervical cytology in pregnancy and the effectiveness of cytologic and colposcopic surveillance of these women. Methods: A retrospective analysis was conducted in pregnant women referred to the colposcopic clinic with abnormal cervical cytologic results above ASCUS between Jan. 2002 and Dec. 2007. The Initial colposcopy was performed at the end of 1st trimester. Cervical cytology and colposcopy were repeated once or twice during remaining period of pregnancy and at postpartum 6~8 weeks. Colposcopy directed cervical biopsies were taken in case of colposcopic abnormalities. Without evidence of invasion, no invasive procedure was attempted during pregnancy. Above CIN2 patients were treated postnatally. The postpartum diagnoses were compared to the worst antepartum impressions and initial cytologies. Results: One hundred three pregnant women were referred to colposcopic clinic for 5 years. There was no invasive cervical cancer antenatally. After delivery, 53 patients were followed up and 17 patients above CIN2 lesions treated. Two microinvasive squamous cell carcinoma and 1 invasive adenocarcinoma were found postnatally. In 33 initial ASCUS cytologies, there were 7 CIN2,3 lesions and 3 invasive cancers. One CIN3 was found in 13 LSIL cytologies. All 7 HSIL patients had CIN3 lesions. There were 2 microinvasive cancers postnatally in 17 antenatal CIN2,3 patients. Conclusion: ASCUS cervical cytologic results in pregnancy have 30% possibility of CIN2,3 and cancer. LSIL results are normal in 85% and HSIL group 100% CIN3. Even though there is 12.5% risk of microinvasion in antenatal CIN2,3 lesions, noninvasive conservative management is reasonable.
