광봉 각도에 따른 초회 삽관 성공률의 비교

김민균 대한마취통증의학회 2007 Anesthesia and pain medicine Vol.2 No.4

Background: It has been recommended that lightwand tracheal intubation be used for cases in which there is difficult airway management. Transillumination of the soft tissue of the neck by the lightwand can lead to successful intubation; however, this depends on skin color, obesity, head position, angle and the bent length of the lightwand. The goal of this study was to compare the success rates of intubation on the first attempt and complications of lightwand orotracheal intubation that occurred when using the lightwand at angles of 60o and 90o. Methods: One hundred forty eight patients of ASA physical status 1 or 2 were enrolled in this study. Patients in whom intubation had previously been difficult as well as patients who had the potential for difficult intubation were excluded from this study. Patients were randomly assigned to one of two groups: The lightwand bent in 60o (LW60) group and the lightwand bent in 90¡o (LW90) group. Anesthesia was performed using propofol (2 mg/kg), fentanyl (1μg/kg) and rocuronium (0.9 mg/kg), and lightwand orotracheal intubation was attempted 2 minutes after the induction of anesthesia. The success rates of intubation, the number of attempts and their duration, as well as hemodynamic changes, resistance to the tube and complications that occurred during the procedure were recorded. Results: In the LW90 group, resistance to the tube during lightwand intubation occurred in a significant number of patients (P < 0.05), however, there were no significant differences observed between the two groups with regard to the intubation success rates on the first attempt, the duration of intubation, hemodynamic changes and complications. Conclusions: Their were no significant differences observed between intubation success rates on first attempt and complications when using a lightwand bent to 60¡o or 90o in patients without any previously known airway abnormalities.

Longstanding, unrecognized staghorn stones remain a major cause of morbidity in the form of pain, infection, and functional impairment of the affected kidney. Squamous cell carcinoma of the upper urinary tract is associated with stone disease and chronic infection, but the association with transitional cell carcinoma (TCC) has not been proven. We report a case of a 73-year-old man presenting with right flank pain with episodes of total gross hematuria for 1 year. An abdominopelvic computed tomography scan showed decreased parenchymal enhancement and staghorn stones in the right renal pelvis and multiple tiny calyceal stones with severe hydronephrosis. The patient underwent a simple nephrectomy. Histopathologic analysis revealed staghorn stones combined with high- grade papillary TCC of the renal pelvis. The tumor was extended into the peripelvic fat and renal parenchyme (pT3NoMo).

벼 색소체 형질전환을 이용한 글리포세이트 저항성 유전자 cp4-epsps의 발현

김민균,강경수 한국식물생명공학회 2006 JOURNAL OF PLANT BIOTECHNOLOGY Vol.33 No.2

Heteroplasmic rice plastid transformant was generated using suspension cells as bombardment materials. PCR analyses confirmed incorporation of aadA and cp4-epsps genes into the rice plastid genome by homologous recombination events via the flanking sequences of the trnI and trnA. Transplastomic calli were actively proliferated when cultured on AAM2 medium supplemented with various concentrations (500-3000 mg/L) of streptomycin in dark condition, and transplastomic suspension cells showed resistance to nonselective herbicide, glyphosate. Through ‘agarose pie selection’ method, heteroplastomic calli, containing considerably high level of transplastome and expressing the CP4 EPSPS protein, were obtained. They were further regenerated to green shoots with healthy roots.

Purpose: Penile fracture is a rare but serious urological condition. Immediate surgical repair is widely accepted as the treatment of choice in penile fracture. The aim of this study is to investigate the long-term outcome of immediate surgical treatment of penile fracture. Materials and Methods: This is a retrospective study of 12 men with penile fracture who were treated in the Department of Urology, Sanggyepaik Hospital, Seoul, Korea from January 2000 to June 2005. Diagnosis was made clinically and was confirmed by cavernosography in all our patients. All patients underwent immediate surgical repair, within two days after trauma, using a degloving incision. The long term results of the immediate surgical repair were evaluated using questionnaire on outpatient department visiting or telephoning. Results: The median patient age was 43 years (range, 18 to 57 years). The median follow-up was 32 months (range, 14 to 60 months). Of these patients, 8 (66.7%) patients were injured during sexual intercourse, whereas 4 (33.3%) patients were injured during masturbation. All patients were treated by immediate surgery. All patients reported satisfactory, painless erectile function; two developed penile curvature and one had a penile nodule. Conclusions: Immediate surgical repair of penile fracture is effective, restores erectile function, and the incidence of complications is low.

건축용 내화 단열재 개발을 위한 제주도 현무암 석분 슬러지 화학조성에 대한 연구

The basalt fiber is expected to become a trend for industrial fibers as they have better properties of heat-resistant, non-combustion, absorbent, soundproof, moistureproof, lightweight, corrosion resistant, and high strength properties. Also, the fiber is found to be non-toxic and harmless to the human body. Therefore, in this study, we analyzed the chemical and mineral compositions of powdered sludge of basalt produced at seven sites on Jeju Island for the development of fire resistance insulating material for a building. The results showed that the basalt stone sludge is made from only sodium calcium aluminum silicate and ferridioside components unlike the basalt rock.

Arachnoid Cyst in Oculomotor Cistern

김민균,최현석,전신수,정소령,안국진,김범수 대한영상의학회 2013 Korean Journal of Radiology Vol.14 No.5

Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

Investigating a Role of Strategic Sourcing and Organizaiotnal Culture on Mitigating Risk in Supply Chain

김민균,채상미 인하대학교 정석물류통상연구원 2014 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.12 No.2

The main objective of this study is to investigate an impact of organizational cultureon supply chain risk and strategic sourcing. It also examines the relationship betweenorganizational culture and strategic sourcing. By collecting 159 survey responses fromsupply, executives and managers of U.S. manufacturing firms, it provides empiricalevidence that organizational culture and strategic sourcing mitigate supply chain risks. Organizational culture also makes a positive impact on the implementation of strategicsourcing. This study emphasizes the importance of cultural impacts to supply executivesand managers in supply chain risk management.
