Objectives : Lumbar radiculopathy is a common disease in oriental rehabilitation medicine. It can be diagnosed by physical examination, plain X-ray, Myelography, CT, MRI, EMG etc. But those methods are not useful in observing the clinical procedure. Objectvie evaluating the clinical procedure is very important in treatment of lumbar radiculopathy. Mehthods : We studied the clinical efficacy of thermography in lumbar radiculopathy during conservative managements. We studied 36 patients with lumbar radiculopathy convinced by MRI. The had low back pain and radiating pain on one side. Thermography had taken before an after 4 weeks treatments, and compared with clinical procedure Results and conclusions : Thermography is not pertinent as a primary diagnostic method in lumbar radiculopathy, but useful in observing the clinical procedure. And it can be recommended as a objective evaluation for lumbar radiculopathy.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

One of the recent procedures, the slip line field theory is adopted to find out the exact blank profile for deep drawing square and rectangular cups with a uniform height. The uniformity of drawn cup heights with ideal blanks by this theory is compared with that from other blanks. Drawing forces and thickness distributions are also described experimentally. From this approach, the use of ideal blanks could be suggested to obtain the deeper and the better square and rectangular cups with uniform heights which reduce the trimming allowance to a minimum.

Film dosimetry as a part of patient specific intensity modulated radiation therapy quality assurance (IMRT QA) has been accomplished to develop the new optimization method of film isocenter offset and to suggest the new quantitative criteria for film doimetry after optimization. Five patients with head and neck cancers were measured in IMRT dosimetry by film method. Optimization method with the local minimum was developed to adjust the film isocenter offset error, which is the biggest part of systemic errors. The mean ratios were 5.33% and 7.09% for 5mm and 1 mm resolution dose data optimization respectively.

LPE법으로 작성한 Bi₂-xSr₂Ca₁+xCu₂O 막(film)의 초전도특성에 관한 연구

신재수 대전대학교 기초과학연구소 1998 自然科學 Vol.9 No.1

LPE법으로 Bi₂-x??Sr₂Ca₁+x??Cu₂O??(x??=0, 0.05, 0.1, 0.2) 막(film)을 작성하여 XPS 측정과 EPMA 측정을 통하여 각 layer에 있어서 원자의 분포상태와 초전도특성을 조사하였다. 작성한 막(film)은 c-축으로 강하게 배향되었으며, x??(융액조성비)의 증가에 따라 c-축의 길이는 단조로이 증가하였고, 임계온도 Tc??는 x??=0.1 부근에서 최고치를 나타내고 있었다. Bi와 Ca의 상호치환에 따라 구조적 변화는 SrO-layer에서 크게 나타나고, Ca-layer에서는 거의 변화가 없이 일정함을 알 수 있었다. Bi의 조성비의 변화는 SrO-layer에 영향을 주며, 이에 따라 초전도 특성도 변화함을 알 수 있었다. X-ray photoelectron spectroscopy(XPS) measurements were performed on the Bi₂Sr₂CaCu₂O?? system prepared by the LPE method using melts with compositions Bi : Sr : Ca : Cu = (2-χ₁) : 2 : (1+χ₁) : 2(χ₁=0, 0.05, 0.1, 0.2). The peak decompositions of Sr3d and Ca2p XPS spectra, together with the EPMA results, elucidated the occupanies of Bi, Sr and Ca atoms on the BiO-, SrO- and Ca-layers. The dependence of the superconducting critical temperature Tc?? and the lattice paramaeter c are explained by the changes of the excess oxygens in the BiO-layer.

In the active sonar development, the reverberation is one of the major factors to be overcome like the clutter in the rader development. Unfortunately real reverberation data in various cases cannot be achieved so easily as real clutter data can be and there is a trend to build a simulator before a complex sonar system is developed. In the sonar simulator, the synthesized reverberation signal is necessary. In this paper we propose an algorithm to simulate the reverberation for the moving active sonar to use it in a simulator, and show some simulated results.

申載熙,卞種秀,朴準奉 慶北大學校 齒科大學 1986 慶北齒大論文集 Vol.3 No.1

butyl cyanoacrylate가 一般的인 縫合絲에 比해 齒 剝離搔爬術後 齒周辯膜의 治癒에 미치는 影響을 糾明하고자 5마리의 雜種犬 ( 6∼8kg )을 利用, 이들의 上下顎 左右 犬齒에 該當하는 頰側 附着齒 에 齒 剝離搔爬術을 施行하고 上記 2가지 方法을 區分하여 樂劑의 塗布 및 縫合을 施行한 後 定한 날에 實驗動物을 儀牲시켜 組織學的 檢鏡을 통해 이를 觀察하여 다음과 같이 結果를 얻었다. 組織學的 所見에서 初期에는 實驗部가 對照部에 比해 下部組織에 淨腫性 纖維素綱과 炎症細胞浸潤이 微弱하였고, 裂溝上皮細胞의 被服과 纖維性 骨膜의 形成이 迅速하였으며 纖維性 結締組織에 의한 齒周 膜과 齒面과의 癒合도 빨리 일어났다. releasing incision 部位에서도 實驗部가 炎症細胞浸潤이 보다 적었고, 肉茅組織의 形成이 迅速히 일어났으며 그 量도 적었다. 그러나 組織學的 觀察의 全 過程을 통해 3週에서는 治癒程度에 있어서 兩者間의 差異가 없었고, 4週에서도 兩者間의 治癒程道에 대한 差異를 觀察할 수 없었다. This is study was made in order to determine the histological changes associated with healing following the use of cyanoacrylates and silk sutures in canine areas where periodontal flap procedures had been carried out. In this experiment 5 adult mongrel dogs were used. The cyanoacrylate on the right side and black silk suture on the left buccal side of maxilla and mandibular canine area, were applied for the fixation of the flap after the periodontal flap surgery. On the experimental days, the experimental areas were examined clinically and sacrificed. Thereafter histological secimens were made following the useal methods and examined with light microscope. The results were as follows : In the histologic observations, the experimental areas as compared with the controls ; There was weak inflammatory cell infiltration and less edematous fibrin mesh formation at the substructure of the flap. The sulcus epithelial cell covering and formation of the fibrous periosteum was made rapidly. The union of periodontal flap and tooth surface by fibrous connective tissue was also made rapidly at the experimental areas. At the areas of the releasing incision less inflammatory cell infiltration and rapidity and small amount of granulation tissue formation were found. But through the entire procedure of the histologic observations, there was little difference in the degree of healing between the two in the 3rd week and it was also impossible to find the difference of healing between the two in the 4 th week.

신재학,이중정,이경수,사공준,김창윤,정종학 大韓産業醫學會 1995 대한직업환경의학회지 Vol.7 No.1

지속적인 주야간 교대작업이 심혈관계 질환의 위험요인에 미치는 영향을 평가하고, 심혈관계 질환의 위험요인들 중 교대작업에 의해 민감하게 영향을 받는 요인들을 조사하고, 교대작업에 참여한 기간과 위험요인들과의 관계를 평가하기 위하여 울산시에 있는 모 자동차공장 생산직 근로자를 대상으로 1993년 4월 20일부터 2개월간에 걸쳐 단면조사를 시행하였다. 교대작업은 하루 2교대로 이루어지며 야간작업조와 주간작업조는 1주일 주기로 순환되었다. 근무기간 1년이상 80%이상을 교대작업에 참여했던 근로자 420명을 교대작업군으로, 교대작업에 참여한 경험이 전혀 없는 생산직 근로자 88명을 대조군으로 하여 연령, 성별, 최종 학력, 현 산업장에서의 근속기간, 입사전 경력, 현재 작업부서, 작업내용 및 직급을 자기기입식 설문지를 통하여 조사하였다. 교대작업에 관해서는 조사당시의 교대작업에 참여여부, 교대작업의 주기와 규칙성 여부, 입사후 지금까지 교대작업에 참여한 기간을 조사하였다. 심혈관계 질환의 위험요인들로서 혈압, 콜레스테롤치, 중성지방, apolipoprotein A-1과 B 등을 측정하였다. 위험요인들의 단순비교에 있어서는 수축기혈압은 교대작업군과 대조군이 각각 122.4±11.9mmHg, 120.0±11.4mmHg로 교대작업군에서 다소 높았고 이완기혈압도 각각 76.5±9.3mmHg, 75.9±9.1mmHg로서 교대작업군에서 다소 높았으나 유의한 차이는 없었다. 콜레스테롤치와 중성지방도 교대작업군에서 다소 높았으나 통계적으로 유의하지 않았다. Apolipoprotein B는 교대작업자가 101.8±19.9mg/dl로서 대조군의 94.2±26.5mg/dl에 비해 다소 높게 나타났으며 통계적으로도 경계역 유의성을 보였으나(p=0.057), apolipoprotein A-1은 apolipoprotein B에 비해 개인적인 변이가 크고 두 군간의 차이를 인정할 수 없었다. Apolipoprotein B와 apolipoprotein A-1의 비는 교대작업군이 0.73±0.20으로 대조군에 비해 높게 나타났다(p<0.05). 비체중은 두 군 모두 약 22로서 유의한 차이를 보이지 않았으나, 1주일 동안 규칙적인 운동을 하는 횟수는 대조군이 1.27±1.5회에 비해 교대작업자가 0.76±1.1회로서 유의하게 적었다(p<0.01). A형 행동양상을 가지는 비율은 교대작업자에서 58.8%로 주간작업자의 51.1%에 비해 다소 높았으나 통계적으로 유의하지는 않았다. 심혈관계 질환의 주된 위험인자들을 종속변수로 하고 교대작업과 다른 위험인자들을 독립변수로한 다중회귀분석에서는 수축기혈압을 종속변수로 채택하였을 때 가변수 교대작업은 회귀계수 2.668로서 수축기혈압을 증가시키는 것으로 나타났으며 (p=0.059), 비체중도 경계역 유의성을 보였다(p=0.053). 이완기혈압에 대한 다중회귀분석에서는 가변수인 교대작업이 유의한 영향을 미치지 않은 것으로 나타났으며, 비체중이 유의한 변수였다(p<0.01). 콜레스테롤치를 종속변수로 하여 실시한 다중회귀분석의 결과는 연령 및 비체중이 증가할수록 콜레스테롤치가 증가하는 경향을 보였으며 가변수인 교대작업이 콜레스테롤치를 증가시키나 통계적으로 유의하지는 않았다. 중성지방에 대한 다중회귀분석에서는 가변수 교대작업이 중성지방을 증가시키는 것으로 나타났으나 통계적으로 유의하지는 않았다. Apolipoprotein A-1의 경우 가변수 교대작업은 apolipoprotein A-1의 수준을 감소시키는 경향을 보였으나 통계적으로 유의하지는 않았다. 그 밖의 다른 변수들 중 apolipoprotein A-1의 수준에 영향을 미치는 변수는 없었다. Apolipoprotein B를 종속변수로한 다중회귀분석에서는 가변수 교대작업은 apolipoprotein B의 수준을 증가시키는 경향을 보였으나 통계적으로 유의하지는 않았다. Apolipoprotein B와 apolipoprotein A-1의 비를 종속변수로 한 다중회귀분석에서는 가변수 교대작업이 apolipoprotein B/Apo A-1을 증가시키는 변수였으며 통계적으로도 유의하였다(p<0.05). 교대작업군을 교대작업에 참여한 기간이 5년 미만인 군과 5년 이상인 군으로 나누어 비교하였을 때 콜레스테롤치, apolipoprotein B 및 Apo B/Apo A-1가 5년 미만의 교대작업군에 비해 5년 이상인 군이 유의하게 높게 나타났다(p<0.05). 교대작업기간이 위험요인에 미치는 영향을 보기 위해 가변수로 교대작업기간을 독립변수로 투입하여 다중회귀분석을 실시하였다. 콜레스테롤치를 종속변수로 한 다중회귀분석에서는 교대작업의 기간이 길수록 유의하게 증가하는 경향을 보였으며(p<0.05), apolipoprotein B도 교대작업의 기간이 길수록 다소 증가하는 경향을 보였으나 통계적으로 유의하지는 않았다. An investigation of effects of shift work on cardiovascular risk factors has been carried out on workers of a motor company in Ulsan, for 2 months from 20 April to 20 June, 1993. This cross-sectional survey was designed to compare the shift workers(n=420) with day workers(n=88). The study subjects were drawn from workers who were employed in twelve hour shift system. A control group who never experienced shift work was drawn from different sections of the factory. Each worker completed a medical and occupational questionnaire, and cardiovascular risk factors such as blood pressure, total cholesterol, triglyceride, apolipoprotein A-1 and B were measured. In univariate analysis, apolipoprotein B and the ratio of apolipoprotein B to apolipoprotein A-1 increased in shift workers. In multiple regression analysis for the systolic blood pressure, shift work was significant independent variable(p=0.059). In multiple regression analysis for the cholesterol, age and body mass index were significant independent variables(p<0.01), but shift work was not a statistically significant independent variable. In multiple regression analysis for the ratio of apolipoprotein B to apolipoprotein A-1, shift work was significant independent variable(p<0.05). Shift workers who have engaged in shift work more than 5 years have an excess of total cholesterol, apolipoprotein B and ratio of apolipoprotein B to apolipoprotein A-1 than those who have engaged in shift work less than 5 years (p<0.05). In multiple regression analysis for the cholesterol, duration of shift work was a significant independent variable(p=0.012). In multiple regression analysis for the apolipoprotein B and ratio of apolipoprotein B to apolipoprotein A-1, duration of shift work was not a significant independent variable.

Bi_2Sr_(2-x)Ca_(1+x)+xCu_2O_(8+d)계 산화물의 초전도 특성 및 XPS 측정

신재수,오승호,장충근 충남대학교 자연과학연구소 1992 忠南科學硏究誌 Vol.19 No.2

We have elucidated the distribution of the Sr and Ca atoms in the Bi_2 Sr_(2-x) Ca_(1+x) Cu_2O_(8+d) system (0≤x≤0.8) by X-ray photoelectron spectroscopy (XPS). The carrier concentration and the superconducting temperature Tc have a maximum at x=0.2 and then monotonously decrease with increasing x. From the XPS measurements, the Sr3d and Ca2p spectra are found to be decomposed into two states. We have clarified the occupation of the Sr and Ca atoms in the Sr- and Ca-layers and found that he deficiency in the Sr-layer have a great influence on superconductivity.

신용섭,윤석화,손수창,이원형,이정은,황원재,김만수,김영주,김혜자,최세진 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.
