        김성구,황성준,김민경,김창성,이덕연,이용근,조규성,채중규,김종관,최성호,Kim,,Sung-Koo,Hwang,,Sung-Joon,Kim,,Min-Kyoung,Kim,,Chang-Sung,Lee,,Doug-Youn,Lee,,Yong-Keun,Cho,,Kyoo-Sung,Chai,,Jung-Kiu,Kim,,Chong-Kwan,Choi,,Seong-Ho 대한치주과학회 2003 Journal of Periodontal & Implant Science Vol.33 No.4

        The goal of periodontal treatment is regeneration of the periodontium. Bone graft and absorbable PLA/PGA membrane have been used for this purpose. In this study, 4${\times}$4mm 1-wall intrabony defects were surgically created bilaterally in the mandible of five male beagles. The control group went through a conventional flap operation, while the experimental group I was treated with absorbable PLA/PGA membranes only, group II was treated with absorbable membrane and calcium phosphate. The results are the following : 1. The defect height was 4.82${\pm}$0.45mm in the control group, 4.93${\pm}$0.79mm in the experimental I group, and 4.92${\pm}$0.62mm in the experimental II group. There was no statistically significant difference among 3 groups(P <0.05). 2. The amount of junctional epithelium migration was 30.90${\pm}$9.92% of the defect height in the control group, 39.16${\pm}$7.51% in the experimental I group, and 38.68${\pm}$12.22% in the experimental II group. There was no statistically significant difference among 3 groups(P <0.05). 3. The amount of connective tissue adhesion was 36.38${\pm}$9.03% in the control group, 14.73${\pm}$3.93% in experimental I group, and 27.87${\pm}$9.70% experimental II group. Experimental group I was a statistically significantly different from control group(P <0.05). 4. The amount of new cementum regeneration was 32.92${\pm}$10.51%, 50.04${\pm}$7.61%, and 39.62${\pm}$12.14% for the control, experimental I, and experimental II group respectively. Experimental group I was a statistically significantly different from control group(P<0.05). 5. The amount of new alveolar bone regeneration was 27.24${\pm}$7.49%, 40.75${\pm}$8.03%, and 36.47${\pm}$15.11% for the control, experimental I, and experimental II group respectively. Experimental group I was a statistically significantly different from control group(P <0.05). The results suggest that the use of PLA/PGA membrane in 1-wall intrabony defect of beagle dogs may promote periodontal regeneration. Further studies are required to determine their regeneration effects.

        체육진흥투표권사업에 적용가능한 뉴미디어에 관한 연구

        김종(Kim Chong), 김성훈(Kim Sung-Hun) 한국체육과학회 2008 한국체육과학회지 Vol.17 No.4

        The purposes of this study were to examine the distribution channels of Sportstoto and service industry in other countries and suggest some distribution channels applicable to Korea's Sportstoto. The research findings were as follows: In Europe, they had a large number of ticket issuing machines and reinforced the Internet service. Some of the European nations including France were about to launch a variety of Sportstoto products through IPTV. Developing various kinds of Sportstoto products for customers through new media-based distribution channels like the case of Europe will be effective in breaking up the concentration of bets and preventing the spread of the gambling spirit. There were four new distribution channels applicable to Sportstoto, and they include mobile, IPTV, WIBRO, and an ad hoc network.

        스포츠토토 유통채널 현황분석 및 개선방안 탐색

        김종(Kim Chong), 김성훈(Kim Sung-Hun) 한국체육과학회 2009 한국체육과학회지 Vol.18 No.2

        This study set out to analyze the distribution channels of Sportstoto through literature study and sales analysis, investigate the customer perceptions of introducing a new distribution channel, and suggest desirable directions for the future distribution channels of Sportstoto. By adopting judgmental sampling, which is one of the nonprobability sampling methods, the investigator sampled the customers of Sportstoto. Total 1,008 questionnaires were used in final analysis. The analysis of Sportstoto distribution channels and the survey led to the following results: first, the channel captain was offline stores, which accounted for over 80% of total sales and had the biggest influences on the distribution. Most of the offline stores sold Sportstoto along with other lottos. And 50% or more of the offline stores were concentrated in Seoul and Gyeonggi Province in terms of the number and sales. Secondly, the official sales site on the Internet provided information about the sales schedule and urgent changes in a rapid manner. Notices were essential since the consumers of Sportstoto tended to participate in bets based on their analysis of their matches. And finally, a new distribution channel should adopt an ideal model of one source-multi use, which modifies the same service contents of sales and game information according to the channel characteristics. Thus it's necessary to make use of channel characteristics on the official online sales site, "Betman," based on the sales and information services.

        임상연구 : 두부 외회전이 우측 내경정맥과 경동맥의 해부학적 위치관계에 미치는 영향

        김순임 ( Soon Im Kim ), 강제현 ( Je Hyun Kang ), 백영희 ( Young Hee Baek ), 김상호 ( Sang Ho Kim ), 옥시영 ( Si Young Ok ), 김선종 ( Sun Chong Kim ) 대한마취과학회 2008 Korean Journal of Anesthesiology Vol.55 No.5

        Background: The purpose of this study was to evaluate the effect of head rotation on the anatomical relationship of the right internal jugular vein (RIJV) and the carotid artery (CA) with using ultrasound images in Korean patients. Methods: We investigated 117 patients (age range: 16-87 years old) who were placed in the supine position, but not in the Trendelenburg position. An ultrasound probe was placed on the right neck at the apex of the triangle formed by the head of the sternocleidomastoid muscle and the clavicle, and it was directed toward the ipsilateral nipple at a 30 degree angle to the coronal plane. For each head rotation (0, 30, 60 degrees), we measured the horizontal diameter of the RIJV and CA, and the percentage of overlap of the CA and the RIJV with using an ultrasound system. Results: The mean RIJV diameter was 18.4±4.3 mm and the mean CA diameter was 7.5±1.2 mm at the neutral head position. Following head rotation, the percentage overlap of the CA and RIJV increased significantly (0°: 32.7%, 30°: 45.4%, 60°: 57.0%) (P<0.05). The percentage overlap of the CA and RIJV in the neutral head position increased more in the patients with a BMI over 25. However, age did not have any effect on the percentage of overlap. Conclusions: Head rotation toward the contralateral side increases the percentage of overlap of the CA and RIJV. To decrease the risk of CA puncture, rotate the head from the neutral position as little as possible when performing RIJV catheterization. (Korean J Anesthesiol 2008;55:538~42)

      • 절제 불가능한 4기 위암에서 예방적 위 공장 우회술의 의의

        김환수,김종석,김종한,목영재,박성수,박성흠,장유진,김승주,Kim,,Hwan-Soo,Kim,,Chong-Suk,Kim,,Jong-Han,Mok,,Young-Jae,Park,,Sung-Soo,Park,,Seong-Heum,Jang,,You-Jin,Kim,,Seung-Joo 대한위암학회 2009 대한위암학회지 Vol.9 No.4

        목적: 진행성 위암 중 수술 소견에서 복강 내 원격전이가 존재하거나 주위 장기에 침윤이 심하여 절제가 불가능한 경우에 위 배출구 폐색을 동반하지 않더라도 예방적 위공장 우회술을 시행하는 경우가 있어, 단순 개복술 시행과 비교하여 그 의의를 알고자 하였다. 대상 및 방법: 1984년부터 2007년까지 고려대학교 의료원에서 수술을 시행 받은 진행성 위암 환자 중 위 배출구 폐색이 없고 절제 불가능한 4기 위암 환자 167예를 대상으로, 후향적 방법을 이용하여 임상병리학적 특성 및 치료성적, 그리고 예후 인자 분석을 시행하였다. 결과: 위 공장 우회술을 시행과 단순 개복술 시행을 비교한 결과, 나이, 성별, 간 전이 여부, 술 후 재원일, 재입원 횟수에서는 유의한 차이를 없었지만, 병소의 위치(P$\leq$0.014), 복막 파종(P=0.001)에서는 유의한 차이를 보였다. 예후 인자 분석에서는 위 공장 우회술을 시행한 군의 생존기간이 1~35.7개월(6.3개월), 시행하지 않은 군이 1~33.4개월(median 4.3개월)로 유의한 차이가 있었으며(P=0.031), 복막전이가 있는 경우 1~31.0개월(median 3.4개월), 없는 경우 1~33.3개월(median 5.8개월)로 유의한 차이를 보였다(P<0.001). 다변량 분석을 통한 독립적 예후 인자로는 복막 전이 여부만이 의미가 있었다(P=0.002). 결론: 절제 불가능한 4기 위암 환자에서 폐색 증상이 없는 경우, 예방적 위 공장 우회술은 생존기간의 연장에서 큰 의의를 가지지 못하는 것으로 생각한다. Purpose: The aim of this study was to evaluate the significance of palliative gastrojejunostomy for treating patients with unresectable stage IV gastric cancer, and as compared with laparotomy for treating patients with incurable gastric cancer. Materials and Methods: We retrospectively studied 167 patients who could not undergo resection without obstruction at Korea University Hospital from 1984 to 2007. They were classified into two groups, one that underwent palliative gastrojejnostomy (the bypass group, n=62) and one that underwent explo-laparotomy (the O&C group, n=105), and the clinical data and operative outcomes were compared according to the groups. Results: For the clinical characteristics, there were no differences of age, gender and liver metastasis between the bypass group and the explo-laparotomy group, but there was a significant different for the presence of peritoneal metastasis (P=0.001). There was no difference between two groups for the postoperative mortality and morbidity. For the postoperative outcomes, the duration of the hospital stay (29.25 vs 16.67) and the frequency of re-admission were not different, but the median overall survival (4.3 months vs. 3.4 months, respectively) was significantly different. By multivariate analysis, the presence of peritoneal metastasis was identified as the independent prognostic factor for incurable gastric cancer. Conclusion: A prophylactic bypass procedure is not effective for improving the quality of life and prolonging the life expectancy of unresectable stage IV gastric cancer patients without obstruction.

        임상연구 : 소아에서 사시 교정 수술 후 Ondansetron과 Dexamethasone의 병용투여가 구토 예방에 미치는 효과

        김순임 ( Soon Im Kim ), 이정석 ( Jeong Seok Lee ), 김수현 ( Soo Hyun Kim ), 옥시영 ( Si Young Ok ), 김선종 ( Sun Chong Kim ) 대한마취과학회 2006 Korean Journal of Anesthesiology Vol.51 No.3

        Background: Postoperative vomiting (POV) is a common complication after pediatric strabismus surgery. The aim of this study was to evaluate the prophylactic antiemetic effects of a combination of ondansetron with dexamethasone after strabismus surgery in children. Methods: In this prospective, randomized, double-blind, placebo-controlled study, 126 healthy children, aged 3-10 years, who underwent strabismus surgery under general anesthesia using sevoflurane were examined. The patients were divided randomly into three groups: Patients who received 100μg/kg ondansetron with 100 μg/kg dexamethasone (OD group, n = 42); 100μg/kg ondansetron (O group, n = 42); and saline as placebo (P group, n = 42) after the induction of anesthesia. The incidence of vomiting, the patient`s distress due to vomiting, the need for rescue antiemetics and parental satisfaction during the first 24 h after surgery were evaluated. Results: The incidence of vomiting in group OD (5%) and group O (17%) during the first 24 h after surgery were significantly lower than in group P (40%) (P < 0.001, P < 0.05, respectively). The level of distress of the patients in group OD during the first 6 h after surgery was significantly lower than in group P (P < 0.05). The parents in group OD were more satisfied than those in group P (P < 0.05). However, the incidence of vomiting, patient`s distress, need for rescue antiemetics, and parental satisfaction were comparable between groups OD and group D. Conclusions: A combination of ondansetron with dexamethasone and ondansetron alone were equally effective in preventing vomiting after strabismus surgery in children. However the combination of ondansetron with dexamerhasone, but not ondamsetrone alone, is more effective in reducing the level of patient`s distress and incresing the level of parental satisfaction than the placebo.

        Two multigene families, high-cysteine A(HcA) and high-cysteine B(HcB), are located within 140 kb region of chorion locus in Bombyx mori. Each family consists of 15 members and one of each members are transcribed in pairs. We report isolation and characterization of HcA and HcB genes of the wild type silkmoth, Bombyx mandarina. In this study, we examined 6 repeating units out of 15 HcA genes and 6 units of 15 HcB genes of B. mori and B. mandarina, respectively, and found that the arrangements and expression units of these are dramatically different. In addition, we found that most of the sequence variations were located within the C-variable region. These results suggest that the likely mechanism of concerted evolution is gene conversion-like event in HcA/HcB gene pairs.
