Comparison of Epidural Ropivacaine and Bupivacaine in Patients Undergoing Lower Extremity Surgery Chul-Jun Mun, M.D., Sang-Gon Lee, M.D., Jong-Suk Ban, M.D. and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea Background: Ropivacaine is an amide local anesthetic structurally related to bupivacaine. A ran-domized, double-blind study was performed to compare the clinical effectiveness of ropivacaine and bupivacaine in patients undergoing lower-extremity surgery. Methods: Forty-nine patients (ASA Ⅰ-Ⅱ) were randomized to receive 15 ml of 0.5% ropivacaine or bupivacaine. Twenty patients received 15 ml of ropivacaine and 20 patients received 15 ml of bupiva-caine at the L3,4 or L4,5 interspace. Parameters measured were the onset time, duration and spread of sensory block, the onset time, duration and degree of motor block, the quality of anesthesia and the heart rate and blood pressure profile during the block onset. Results: Demographic characteristics were similar among the groups. Seven patients were excluded from the study due to technical failure of the block, two patients were excluded due to insufficient data. The onset and duration of analgesia at T10 dermatome (mean ?? SD) was 18.9 ?? 7.0 minutes and 187.5 ?? 34.6 minutes respectively for ropivacaine, and was 15.2 ?? 8.8 minutes and 187.8 ?? 40.0 minutes respectively for bupivacaine. Maximum block height (mean ?? SD) was T6.5 ?? 2.0 for ropivacaine and T6.4 ?? 2.0 for bupivacaine. The incidence of complete motor block (Bromage scale 3) was low in the ropivacaine group, being 3/20 for ropivacaine and 12.20 for bupivacaine. Conclusions: The sensory blockade profile of ropivacaine, administered epidurally, is similar to that obtained with an equal dose of bupivacaine. However motor blockade with ropivacaine is less intense, less frequent, and of shorter duration than with bupivacaine. (Korean J Anesthesiol 2001; 41: 434~438)

이상우,정대업,이수열,차상곤,심명석 대한건축학회 2003 대한건축학회논문집 Vol.19 No.4

This study aims at providing useful data for the design of underground stations through an extensive survey of acoustic properties in underground stations in Seoul. In order to improve the sound efficiency at the underground station, sound characteristics in the space of the underground station were studied. Architectural features of underground stations located in Seoul were examined by visiting every site and analyzing drawings. The distinction in architectural features of this study resulted in the line-side section, the shape of under-platform section and ceiling material. Number of underground stations was selected and categorized based on architectural features, such as line-side section, the shape of platform section and ceiling material. Each selected station was revisited and the noise levels were measured and compared with the architectural features. The study found that the Sum-Sik type is more efficient than the one of the Sang-Dae-Sik type, which can be used for subway stations. The semi-circular section for the railway-side seems to contribute on the attenuation of noise transmitting from trains to the platform. In addition, the aluminum absorbing panel, net luber and zinc plate (panel 40% and net 60%) as ceiling meterial are more efficient than the horizontal aluminum spendral panel, vertical aluminum spendral panel with line and zinc plate (panel 40% and net 60%), respectively.

Lee, Gun Sang,Lee, Myung Ki,Kim, Woo Jae,Kim, Ho Sang,Kim, Jeong Ho,Kim, Yun-Suk The Korean Neurosurgical Society 2017 Journal of Korean neurosurgical society Vol.60 No.1

Objective : We assessed the surgical results of bipolar release in 31 adult patients with uncorrected congenital muscular torticollis (CMT) and more than 12 months of follow-up. Methods : Thirty-one patients underwent a bipolar release of the sternocleidomastoid muscle (SCM) and were retrospectively analyzed. The mean follow-up period was 14.9 months (range, 12-30). The mean age at time of surgery was 30.3 years (range, 20-54). Patients were evaluated with a modified Lee's scoring system, cervicomandibular angle (CMA) measurement, and a global satisfaction rating scale using patient self-reporting. Results : The modified Lee's scoring system indicated excellent results in 4 (12.9%) patients, good in 18 (58.1%), and fair in 9 (29.0%) at the last follow-up after surgery. The improvements in neck movement and head tilt were statistically significant (p<0.05). The preoperative mean CMA was $15.4^{\circ}$ (range, 5.4-29.0), which was reduced to a mean of CMA of $6.3^{\circ}$ (range, 0-25) after surgery (p<0.05). The global satisfaction rating scale was 93.7% (range, 90-100). A transient sensory deficit on the ipsilateral lower ear lobe was noted in three cases. No significant permanent complications occurred. Conclusion : Bipolar release of the SCM is a safe and reliable technique for the treatment of CMT in adults.

The Role of Multiple Mediating Effects of SNS Channel between Perceived Quality and Revisit Intention in Coffee Concept Shops

Lee,Jee Eun,Lee,Sang Suk 한국상품학회 2021 商品學硏究 Vol.39 No.5

The purpose of this study is to examine the relationship between the perceived quality and revisit intention of the use of SNS, and then verifies the mediating role of the SNS channel between them. To achieve the purpose of this study, a total of 350 questionnaires were distributed at various coffee concept shops in the Korean metropolitan area (Seoul / Gyeonggi), including global / domestic brands. After removing the response with the missing information, the sample was 320 (91.4%). A structural equation model using AMOS 20.0 tested the hypotheses. Hypotheses are tested and confirmed by analyzing Korean coffee concept shops and the results have shown that information sharing and interaction of SNS play an important role in understanding perceived quality and revisit intention. Moreover, this study empirically verifies that when customers recognize the quality of products, including service and experience quality, they use SNS channels to visit the coffee shop again. The result of the study supported that information sharing and interactivity of SNS played critical roles in understanding perceived qualities and revisit intention. We empirically provide evidence that product quality of perceived qualities has direct positive in fluence on SNS channel and revisit intention. In addition, information sharing and interactivity of SNS channel has indirect significant impacts on intent to revisit. The result of research has shown that product quality had crucial impact on SNSs channel than service or experience quality. The study also shows that increasing the quality level of a product has a positive relationship with social media channels, which in turn can have a positive effect on information sharing and interactions. This study empirically examines that when customers perceive a product quality including service and experience quality, it induces them to use SNS channel, which eventually make them to revisit the store.

이난영,이선숙,이창섭,이상호 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.1

석회화 치성낭은 상악 전치부에 호발하는 발육성 치성낭이나 조직학적 소견이 다양하고 따라서 분류 체계도 다양하다. 악골 내에서 느리게 진행되는 무통성 종창이 일반적이며 24-30%에서 매복치 및 치아종과 연관되어 나타난다. 피복 상피에 나타나는 유령세포는 결합 조직에 노출되어 석회화 조직을 형성한다. 이 증례는 14세 여아의 상악 견치부에 발생한 치아종을 동반한 석회화 치성낭으로, 매복된 상악 좌측 견치 치관 주위로 경계가 명확한 방사선 투과성 병소와 다발성의 방사선 불투과성 석회화 물질이 혼재된 병소였다. 조직병리학적으로 중층 편평상피로 이장되어잇고 상피 내에 유령세포가 관찰되었다. 석회화된 물질은 복합 치아종의 소견을 보여 Preatorius의 조직학적 분류에 의한 석회화 치성낭 Type IB로 진단되었다. 병소의 적출 및 병소에 이환된 견치 발치를 시행하였다. 현재 염증 소견이 관찰되어 병소에 이환된 상악 좌측 제1소구치는 치수치료를 시행하였으며 환아 및 보호자가 포괄적인 교정 치료를 원하여 현재 공간 유지 장치를 장착 중이다. The calcifying odontogenic cyst(COC) predominantly affected Maxillary anterior segment and it is developmental cyst. But COC showed diverse terminology or classification, clinicopathologic features as well as its biologic behavior. COC usually presents as slowly enlarging but otherwise symptomless swelling. Association with impacted teeth and odontoma is described in 24~30%. The epithelial lining of COC(ghost cell) appears to have ability to induce the formation of dental tissues in the asjcents connective tissue wall. This case is a COC associated with a odontoma involving an impacted left maxillary canine in 14-year old female child. Radiographic examination revealed a well-demarcated radiolucent lesion partially occupied by a radiopaque mass, involving the left canine. The histologic sections showed cystic cavity lined with ameloblastic epithelium containing ghost cell masses with regular and irregular shape odontoma. The final pathologic diagnosis was calcifying odontogenic cyst with odontoma(Type IB by Preatorius). Enucleation and elimination of the included tooth were performed. Now endodontic treatment was preformed on the 1st premolar of the upper left jaw, which had a lesion. And the patient and their parents want to have the orthodontic treatment performed and would like to keep the space maintainer.

박상철,이동환,신상만,이상주,박준수,최석민,안재억 순천향대학교 1992 논문집 Vol.15 No.2

Using the infrared interactance(NIR method), the percentage body fat in 1,401 Korean children, aged 6-18years, was evaluated for normal and standard values. Correlation of percentage of body fat with age, weight, height, overweight(%), Kaup index and Rohrer index was also analyzed. The following results were obtained ; 1) In all the subject, weight and height showed standard growth(50-90 percentile) compared to growth data of korean children. 2) The percentage of body fat was decreased with increasing age and was measured higher in female than male. 3) The percentage of body fat was decreased with increasing height in both sex. 4) The percentage of body fat correlated negatively with age, heght, weight in both sex. In boys, the Rohrer index appeared to have a significant positive correlation with the percentage of body fat. (r=0.52454) In girls, the overweight(%) appeared to have a significant positive correlation with percentage of body fat. (r=0.56994) The Kaup index had no correlation with the percentage of body fat. This NIR method is safe, non-invasive, rapid, easy to use, and may be useful predict percentage of body fat, especially in the mass screening.

저자들은 67세 남자 환자에서 위부분절제술 시행 후 cisplatin와 etoposide의 복합항암화학요법을 실시한 위신경내분비암 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. The existence of gastric neuroendocrine carcinomas had been scarcely recognized. When present, the correct diagnosis is seldom made before surgery. The recognition of these tumors can be problematic for the pathologist. Some of these tumors have "small cell" appearance by light microscopic examination, but others only be called "poorly differentiated carcinoma". But tremendous advances in immunohistochemistry in the last 15 years have yielded powerful tools to the pathologist in diagnosing these tumors. We experienced a case of neuroendocrine carcinoma of the stomach. The patient was a 67-year-old male and visited our hospital with epigastric pain. Subtotally resected stomach showed 3.5×4×5cm sized ulcerated tumor that was located at lesser curvature. Final diagnosis was neuroendocrine carcinoma, which stained positively for synaptophysin immunohistochemically. Herein, we report a case of neuroendocrine carcinoma of stomach and review the literature.

Phosphorus Removal in Pilot Plant Using Biofilm Filter Process from Farm Wastewater

Shin, Sung-Euy,Choi, Du-Bok,Lee, Choon-Boem,Cha, Wol-Suk The Korean Society for Biotechnology and Bioengine 2006 Biotechnology and Bioprocess Engineering Vol.11 No.4

Various environmental conditions affecting total phosphorus removal from farm wastewater in a biofilm filter process were investigated using loess balls and Chromobacterium LEE-38 at a pilot plant. When Chromobacterium LEE-38 was used, the removal efficiency of total phosphorous was approximately 10- or 5-fold higher than that of Acinetobacter CHA-2-14 or Acinetobacter CHA-4-5, respectively. When a loess ball of $11{\sim}14mm$ manufactured at a $960^{\circ}C$ calcining temperature was used, the removal efficiency of total phosphorous was 90.0%. When 70% of the volume fraction was used, the maximum efficiency of total phosphorus removal was 93.1%. Notably, when the initial pH was in the range of 6.0 to 8.0, the maximum removal efficiency of total phosphorus was obtained after 30 days. When the operating temperature was in the range of 30 to $55^{\circ}C$, the maximum removal efficiencies of total phosphorus, 95.6 to 94.6%, were obtained. On the other hand, at operating temperatures below $20^{\circ}C$ or above $40^{\circ}C$, the removal efficiency of total phosphorous decreased. Among the various processes, biofilm filter process A gave the highest removal efficiency of 96.4%. Pilot tests of total phosphorus removal using farm wastewater from the biofilm filter process A were carried out for 60 days under optimal conditions. When Acinetobacter sp. Lee-11 was used, the average removal efficiency in the p-adsorption area was only 32.5%, and the removal efficiencies of chemical oxygen demand (COD) and biological oxygen demand (BOD) were 56.7 and 62.5%, respectively. On the other hand, when Chromobacterium LEE-38 was used, the average removal efficiency was 95.1%, and the removal efficiencies of COD and BOD were 91.3 and 93.2%, respectively.

Chemical Lumbar Sympathetic Block: Comparison of One- Versus Two-needle Techniques Chul-Jun Mun, M.D., Kyu-Jong Lee, M.D., Sang-Gon Lee, M.D., Jong-Il Kim, M.D.^* Jong-Suk Ban, M.D., and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea ^*Kim Jong Il Pain Clinic, Daegu, Korea Background: It was frequently noticed in the course of performing a two-needle sympathectomy, that satisfactory spread of contrast solution could be produced by injection through only one of the needles. This led to a closer examination of the merits of single-needle technique. Methods: Forty patients were randomized into two groups. Patients in the single-needle group (n = 20) were injected at the second or third lumbar sympathetic ganglia, while patients in the two-needle group (n = 20) were injected at the second and thired lumbar sympathetic ganglia. Lumbar sympathetic blocks were performed using 3 ml of alcohol and the spread of injectate was verified with C-arm fluoroscopy. The indicators of a successful sympathetic block are increasing skin temperature, decreasing pain, and anhidrosis in the distal extremity. Results: The duration of anhidrosis was 12.2 ?? 2.6 months (mean ?? SD) in the single-needle group versus 13.6 ?? 3.6 months (mean << SD) in the two-needle group. Conclusions: As these results were not significantly different from those obtained in patients having considered to be effective for a neurolytic ;i,bar sympathectomy.
