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.

Trauma is one of the most common causes of death. Recently, injury severity score(ISS) is widely used to evaluate and classify the patients with multiple injury. Trauma score(TS) was developed as a means of providing rapid accurate assessment of the injured patient. Authors conducted a review of trauma patients who visited the emergency department of YongDong Severance Hospital from September 1992 to August 1993. ISS and TS were collected from comprehensive initial evaluation. The results were as follows : 1) The subjects were 10.2%(2,666 patients) of total 26,202 emergency patients. 2) Male to female ratio was 2.1 : 1. The age distribution was highest under 10 year(24.9%). The mean ISS was 3.5, and the mean ISS increased with ago. 3. Analysis of injury mechanism showed high incidence of traffic accident(35.3%), blunt trauma 25.7%, fall 24.2%, stabbing 10.7%, and others 4.3% in order. 4. The 8.0% of patients were admitted after initial management and their mean Iss was 12.6 mean TS was 15.5. 5. Among admitted traffic accident patients, the mean ISS of passenger T.A., pedestrian T.A. and driver T.A. were 19.0 ±9.9, 14.4 ±10.6, and 11.3 ±7.7 respectively. 6. Among 42 mortality cases, 25 patients were D.O.A. and 17 were expired. The mean ISS of D.O.A. Patients was 30.0; the mean Iss and mean Iss and mean TS of expired patients were 28.3 and 11.8 respectively. 7. The most common cause of death was head trauma(66.7%). 8. By comparing the ISS and TS of admitted and expired patients, mortality occurred above 16 point of ISS. The mortality increased with increasing ISS, but it was influenced by the trauma site and the severity of the particular injury site. Mortality also occurred below 15 point of TS, the mortality increased inversely with TS, and the mortality with TS, and the mortality was high below 13 point (above 40%).

정신분열병 환자의 반응시간

최형식,정범석,김한규,송현주,이재원,김창윤 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.5

연구배경: 주의력은 인지적인 정보처리과정(information processing)의 가장 기본적인 단계이다. 반응시간 (reaction time)은 주의력을 가장 잘 반영하는 검사 중 하나로서, 자극이 제시된 후 반응이 시작되기까지 반응 여부를 결정하는데 걸리는 시간인 판단 시간(decision time)과 반응이 시작되면서 목표에 도달할 때까지 시간인 운동시간(motor time)으로 나누어 볼 수 있다. 기존의 연구결과로는, 정신분열병 환자군에서 반응시간의 수행이 떨어져 있다는 보고는 많이 되어왔으나 차이가 없다는 보고도 있으며, 판단시간과 운동시간 중 어느 부분에 장애가 있는지 명확하지 않다. 또한 반응시간 측정값은 질병의 진단적 유형(diagnostic subtype), 증상, 경과 등의 영향을 받으며 개체간의 변동(inter-individual variation)이 크고, 같은 피험자라도 측정시점이 다를 때마다 차이를 보이는 개체내 변동(intra-individual variation)이 커서 검사결과마다 차이를 보이고 있는 상태이다. 목적: 환자군은 개체간 변동이 크고 다른 임상적 요소에 의해 영향받는 점을 고려하여, 임상적으로 안정적인 경과에 있는 정신분열병 환자만을 대상으로 정상인 군과 반응시간의 차이를 비교하고자 하였다. 또한 반응시간을 판단시간과 운동시간으로 나누어 측정하여 각각을 비교분석 하고자 하였고, 개체내 변동이 큰점을 고려하여 25회 반복 측정을 실시하고 이에 따른 변동의 경향성을 조사하고자 하였다. 방법: DSM-Ⅳ에 의해 '정신분열병'으로 진단된 환자로서, 급성기 이후 항정신병약물을 유지하고 있으며BPRS(brief psychiatric rating scale) 30점 이하의 임상적으로 안정적인 상태가 3개월 이상 유지된10명이 환자군으로 포함되었고, 정상인은 자원자 10명이 포함되었다. 검사도구는 비엔나 테스트 시스템 반응유닛(Reation Unit) 파라미터 S8을 이용하였다. 총 6가지의 자극이 무작위로 1측정시기(session) 당 총 32회 주어지고, 피험자는 이중 특정 자극에 8번만 반응하도록 되어 있다. 시작 전 1회 연습 후 총 25측정시기를 5분 간격으로 반복하였다. 반응 시간을 판단시간과 운동시간의 합으로 정의하고 세 가지 모두 컴퓨터를 이용하여 자동 측정되었다. 반응·판단·운동 시간의 비교에는 반복 측정을 고려한 분산분석(repeated measures analysis of variance)을 사용하였다. 결과: 환자군은 정상인에 비하여 유의하게 반응시간의 수행속도가 저하되어 있었다(p<0.01). 판단시간과 운동시간으로 나누어 볼 때, 환자군에서 판단시간이 유의하게 느렸고(p<0.01), 운동시간은 수행저하의 경향을 보였으나 통계적으로 유의하지는 않았다. 25회 반복측정시 양군 모두 측정시기에 따른 유의한 변화를 보였고(p<0.01), 환자군의 반응시간은 개체간의 차이뿐 아니라 개체내 변동이 큰 경향을 보였다. 옳게 반응한 횟수(correct response)는 환자군에서 저하되는 경향을 보였으나 통계적으로 유의하지는 않았다. 고찰: 정신분열병 환자군에서 판단시간이 유의하게 저하된 것은, 반응시간의 저하가 운동요소 보다는 인지적 요소에 의한 것임을 시사하는 것으로, 정보처리과정의 기본적인 단계인 주의력 장애를 보여주는 것으로 생각된다. 비교적 안정적이고 임상적인 특성이 동일한 환자군에서도 반응시간이 대조군에 비해 큰 개체간 차이와 개체내 변동성의 경향을 보였으며, 이는 단순한 측정오차라기 보다는 정신분열병 환자군의 인지기능의 특성을 반영하는 것으로 생각된다. 중심단어:정신분열병·반응시간·판단시간·운동시간·개체간 변동·개체내 변동. The reaction time(RT) has been known to reflect attention that controls the flow of information processing. Extensive research has demonstrated cognitive impairment in schizophr-enia subjects using RT taske. However, little work has been done examining the relative contribution of DT(decision time) and MT(motor time) to slowed RT in schizophrenics. Also, recent investigators have observed that schizophrenic patients exhibit larger intra-individual variability in RT than do normal comparison subjects. The purpose of this study, using multi-stimulus convergent RT task, was to explore the speed of RT, relative contribution of decision time(DT) and motor time(MT) to slowed RT, overall sequential profile in 25 repeated-time measurements in 10 schizophrenic out-patients and 10 normal control subjects. Overall reaction time and decision time were slower in schizophrenic subjects than in normal controls. The motor time was not shown to be significantly different between the two groups with 0.05 significance level, although there was some trend indicating schizophrenic subjects were slower consistently in repreated measurements over time. These results suggested that the slower reaction time in schizophrenic subjects was mostly determined by cognitive component, decision time rather than motor time. Sequential profile of repeated measurements showed greater intraindividual and interindividual variations in schizphrenics than in normal controls. These results indicate that high variabilities are not merely measurement errors but characteristic of schizophrenic psychopathology. KEY WORDS: Schizophrenia·Reaction time·Decision time·Motor time·Inter-individual variation·Intra-individual variation.

We can say Shamanism is the Korean religious Phenominon from ancient times. In addition, foreign religions had been brought in Korea and they had intermixed on the substructure of shamanism and then a new folk religion has been formed. We, human beings, who have blessed that we remove evil, call happiness, treat a desease, invoke a good harvest, invoke having a son and the dead enter into paradise from old times, have been relied upon the ritual of shamanism for our existential problem, but the Mu-dang(Gut: which is a ritual performed by a shaman) of traditional folk customs is now gradually going out of sight and even the historical meaning and function are becoming forgotten. In Chonnam district, Sam-sol-yang Gut in which a shaman puts on a mask like a ghost-face, sings and performs a dramatic Gut(or, a dramatic ritual), was widely prevalent, but it is difficult to see the unique Mu-gut(or, shamanistic ritual) in these days. By good luck have we found that Sam-sol-yang Gut remaining only in Sunchon district is being performed by a hereditary shaman. This is the shaman who has been inherited since six generations and has a Dang-Gol Pan in Sunchon district. Sam-sol-yang Gut is a hereditary shaman song type and a Mu-gut which prays for the healing of a mental patient by the help of god. We think this Gut becomes good data in examining the shamanistic religions and its chant and the story about god are the works which drives away devils and have a lyric structure. The purpose of this paper is to supply the classical literature and the folklore and the like with several shamanistic data and is to study the interpretation of the shaman song, its rhythm and the structure of the ritual and the god's response and peculiarity of the Mu-gut so as to examine the original thoughts and trace the meaning to its origin as we should have carried into the fieldwork of Sam-sol-yang Gut. And also the result of this study is very helpful to the ontological interpretation of Korean shamanism and in addition is more meaningful in arranging the transmissive data which are going away.

광촉매 산화반응에서 촉매의 비표면적과 기공 크기가 활성에 미치는 영향

오송택,최재석,이한수,이호인 한국공업화학회 2003 응용화학 Vol.7 No.2

Mesoporous TiO₂was prepared using esterification between poly ethylene glycol(PEG) and acetic acid, and was applied to the photocatalystic decomposition of 2-isopropyl-6-methyl-4-pyrimidinol (IMP), cyanide ion, and rhodamine B (RB) in order to study the effect of surface area and pore size on the activity. When catalysts had similar specific surface areas, the activity of photocatalytic decomposition of IMP was proportional to the pore size due to more facile diffusion into the pore. However, in case of cyanide which size is much smaller than the pore size of TiO₂the activity was proportional to the specific surface area, while a very large size molecule of RB caused low activity due to difficulty in diffusion into the pore.

The diffuse sclerosing variant (DSV) is a rare malignant tumour that accounts for 0.7-5.3% of all papillary thyroid cancers. DSV tends to occur at a younger age and has a higher incidence of cervical lymph node metastases, compared with papillary thyroid carcinoma. A 62-year-old female patient diagnosed thyroid nodule with diffuse and mild increased 18F-deoxy-glucose (FDG) on FDG positron emission tomography (PET)-computed tomogram (CT) scan. The ultrasound images showed typical findings of DSV such as diffusely enlarged thyroid lobes and diffusely scattered microcalcification. We performed this patient ultrasonography guided fine needle aspiration and cytologic analysis revealed papillary carcinoma. Total thyroidectomy with central compartment node dissection and lateral lymph node dissection was performed and finally diagnosed DVS. The authors report this case with literature review.

TiO_2 was prepared through esterification between polyethlene glycol(PEG)and actic acid, and was applied to the photocatalytic decomposition of 2-isopropy1-6-nrthy1-4-pyrimidinol. Photocatalytic activity was increased with the increase of pore size which was produced by prmoving PEG diring calcination When excess amout of H_2O was added the catalytic removing PEG during calcination When excess amout of H_2O was added, the catalytic activtiy and pore size dercased as a result of direct hydrolsis vetween titanium precursor and water added. When the amount of PEG increased, esterification occurred more but the activity and the surface area of TiO_2 were derased, esterification because of agglomeration among PEG molecules.

Abstract - This paper presents a fault location algorithm when there are parallel circuits in power system networks. In transmission networks, a fault location method using the distribution factor of fault currents is introduced and in distribution networks a method using direct 3-phase circuit analysis is developed, because the distribution networks are unbalanced. The effect of parallel circuits in fault location is studied in this paper. The effect is important for the range of protecting zones of distance relay in transmission networks and fault location in distribution networks. The result of developed fault location algorithm shows high accuracy in the simulation that using the EMTP.
