목적: 버찌씨 수술은 복압성 요실금 수술에 효과적인 수술로 여겨져 왔다. 요실금의 원인이 내인성 요도 괄약근의 결손소견 없이 요도의 과운동성으로 인한 경우 버찌씨 수술이 일반적으로 추천되어진다. 본 연구에서는 복강경 버찌씨 수술에서 최씨 훅의 유용성에 대해 알아보고자 하였다. 연구방법: 2000년 10월부터 2005년 3월까지 본원에서 복강경 버찌씨 수술을 시행받은 47명의 환자를 대상으로 하였다. 27명은 고전적 복강경 버찌씨 수술을 시행하였고 20명은 내골반 근막을 Cooper 인대를 부착하는데 유용한 본원에서 고안한 최씨 훅을 이용하여 복강경 버찌씨 수술을 시행하였다. 결과: 고전적 복강경 버찌씨 수술을 시행한 군과 최씨 훅을 이용한 복강경 버찌씨 수술을 시행한 군의 평균 나이, 분만력, 폐경률, BMI는 두 군간에 통계학적으로 유의한 차이를 보이지 않았다 (p>0.05). 수술 시간은 고전적 복강경 버찌씨 수술은 90.52±15.32분, 최씨 훅을 이용한 복강경 버찌씨 수술은 38.50±10.14분으로 최씨 훅을 이용한 경우 수술시간이 통계적으로 유의하게 짧았다 (p<0.05). 두 군간에 재발률 및 합병증 발생은 통계적 유의성을 보이지 않았다 (p>0.05). 결론: 본 연구에서 본원에서 고안한 최씨 훅을 이용하여 복강경 버찌씨 수술을 시행한 결과 수술 시간을 단축시킬 수 있었으며 수술 효과는 기존 방법과 동일하게 관찰되었다. 이에 최씨 훅은 복강경 버찌씨 수술에서 사용할 때 집도자의 봉합 과정을 단순화시켜 수술 시간을 단축시키므로 복강경 버찌씨 수술에 용이한 기구이다. Objective: Burch operation has been effective method for the treatment of stress incontinence. Burch operation is a well-accepted procedure for treating stress urinary incontinence secondary to urethral hypermobility without intrinsic sphincter deficiency and is the reference standard with which other procedures are compared. This study is to evaluate the effectiveness of the Choi`s hook in laparoscopic Burch operation. Methods: This study included 47 patients who had undergone laparoscopic Burch operation from October 2000 through March 2005. Of these 47 patients, 27 patients underwent traditional laparoscopic Burch operation (Group 1) and 20 patients underwent laparoscopic Burch operation with Choi`s Hook on anchoring the endopelvic fascia to the Cooper`s ligament (Group 2). Results: The mean age of patients of Group 1 was 55.6±9.37 years of age and that of Group 2 was 56.0±5.93 years of age. There is no difference in the mean age of patients (P>0.05). The mean operating time was 90.5±15.32 minutes for Group 1 and 38.5±10.14 minute for Group 2. The mean operating time was shorter in Group 2 than Group 1 (P<0.05). There was no difference in recurrence rate and complication rate between Group 1 and Group 2 (P>0.05). Conclusion: We performed laparoscopic Burch operation with the Choi`s Hook on anchoring the endopelvic fascia to the Cooper`s ligament. When we compared traditional laparoscopic Burch operation with laparoscopic Burch operation with Choi`s Hook, we could shorten the operation time using the Choi`s Hook.

Recently, there has been an increase in the demand for the machining of high-hardness materials using diamond electro-deposition tools. However, a systematic analysis of these tools in terms of machinability has not been performed yet. In this study, a tool design optimization is performed to improve the machinability of diamond electro-deposition drills in drilling SiC ceramic materials. Each drill is analyzed using FEM analysis and the results are compared with the corresponding experimental results. Additionally, the particle drop rate and surface roughness of the machined surface are analyzed for each drill. Consequently, we discover that the most important aspect in drilling using a diamond electro-deposition drill is the proper discharge of the machined chip. Furthermore, we determine the optimal drill shape for the improvement of machinability.

저자들은 71예의 자궁경부종양을 대상으로 E-cadherin, β-catenin 발현 정도 및 분포 양상을 임상병기, 환자의 나이, 종양의 진행정도 및 림프절 전이여부와 관련있는지 알아보고자 하였다. 연구 방법 : 자궁 경부 편평상피 종양 중 심한 이형성증 3예, 상피내암 22예, 미세침윤성 암 10예, 침윤성암 36예 총 71예의 조직절편을 면역조직화학염색을 하여 E-cadherin, β-catenin의 염색 정도와 분포 양상을 조사하여 자궁경부암의 조직학적 분화정도, 임상 병기와 관련이 있는지 분석하였다. 결과 : E-cadherin은 71예 중 54예에서 (76.1%), β-catenin은 71예 중 53예에서 (74.6%) 변이성 발현을 보였다. E-cadherin과 (p<0.005) β-catenin의 (p<0.005) 비정상 발현은 종양의 진행, 임상병기와 관련 있었다. 결론 : E-cadherin, β-catenin의 비정상 발현이 자궁경부 편평상피 종양의 조직학적 분화, 임상병기와 관련 있는 것으로 보아 E-cadherin, β-catenin이 편평상피 종양의 조직학적 분화와 종양의 진행에 관여할 것으로 추정된다. Objective : The objective of this study was to determine relationship between alteration of expression of E-cadherin, β-catenin and tumor progression, clinical stage, lymph node metastasis, age of patients with uterine cervical cancer. Methods : The authors evaluated the immunohistochemical expression pattern of E-cadherin and β-catenin in relationship with tumor stage and clinicopathologic parameters in 71 cervical neoplasia including 36 cases of squamous cell carcinoma (SCC), 10 cases of microinvasive SCC, 22 cases of squamous cell carcinoma in situ, and 3 cases of severe dysplasia. Results : There were aberrant expression in 76.1% of E-cadherin (54 of 71) and 74.6% of β-catenin (53 of 71) in the cervical cancer. There was positive correlation of aberrant expression of E-cadherin with tumor progression and clinical stage (<0.005). There was positive correlation of aberrant expression of β-catenin with tumor progression and clinical stage (<0.005). Conclusion : These results suggest that degree or the pattern of E-cadherin, β-catenin, and E-cadherin/β-catenin complex may be related to histologic grade and clinical stage of uterine cervical cancer.

There has been a recent increase in the use of diamond tools with the increase in the use of high hardness materials. In this study, the machinability of high hardness ceramic materials was evaluated using an electro-deposited diamond drill. Specifically, the machinability of four types of drills was analyzed by changing the drill shape and electro-deposition method of the diamond particles to address the limitations of commonly used diamond drills. In addition to varying the cutting speed and feed rate, the cutting torque, diamond particle fall-out rate, and roughness of the machined surfaces were compared and analyzed. The results of this study will be helpful in tool design and setting the appropriate machining conditions to improve the machinability of high hardness ceramics using electrodeposited diamond tools.

A rate com;lication of hysterectomy is complete prolapse and inversion of vagina. This can occur whether the hysterectomy was abdominal or vaginal and cystocele and/or enterocele is often associated with this condition. Traditionally, prolapse has been treated by surgery, the types of operation for prolapse are generally but not always, carried out through the vaginal rather than through the abdominal surgical route. We experienced five cases who had repair of posthysterectomy vaginal vault prolapse by transabdominal sacral colpopexy and report with brief review of literatures.

코칭(훈련)의 New Paradigm - 통합기능훈련

최상준(Sang-Joon Choi) 한국코칭능력개발원 2008 Coach Vol.24 No.2

The goal of coaching and training is to acquire function, pragmatic function in particular. Pragmatic function refers to the ability to create movement as desired. This function is the result of the coordination and interdependent harmony existing in whole body systems, including the nervous, vestibular, vascular, and musculoskeletal systems. The Integrated Functional Training (IFT) program not only integrates OKCE and CKCE, but also it trains all elements including muscular strength, flexibility, endurance, agility, proprioception, stability, cardiopulmonary function, and coordination, multiphasically at the same time. As IFT is integrative, progressive, creative, safe, fun and not restricted by time and space, it applies to everyone. Patients to everyday people, amateurs to specialists, people of all ages, and athletes from all sports can enjoy its benefits. IFT, which pursues the acquisition of pragmatic function, provides a new paradigm for coaching and training fit for the 21st century, and it will produce revolutionary changes in the fitness industry.
