Rhabdomyolysis may be defined as a clinical and laboratory syndrome which releases muscle cell contents into the plasma, such as creatine phosphokinase, due to skeletal muscle injuries. It can be the result of many diverse causes including muscle disease, ischemia, genetic disorder, metabolic disorder, infectious disease, drugs, comatose state, trauma or vigorous exercise that can lead to acute renal failure as a complication. Since first reported in 1941, rhabdomyolysis-induced acute renal failure has been documented many times, and the major causes of this disease are carbon monoxide poisoning, snake bites, and etc in Korea Reports of acute renal failure after exercise-related rhabdomyolysis with myoglobinemia are rare. We report a case of acute renal failure caused by exercise-related rhabdomyolysis in a 20 year old man.

Purpose: The purpose of this study was to compare the efficacy of heparin flushing and normal saline flushing in maintaining patency of central venous catheters(CVCs), and to investigate relative risk factors of CVCs' occlusion. Method: A total of 159 patients who had been inserted with CVCs were included in the department of hemato-oncology of S hospital. The heparin group consisted of 74 patients with 10u/ml diluted heparin flushing from 23 November 2004 to 15 January 2005, and the normal saline group consisted of 85 patients with 0.9% normal saline flushing from 19 January to 31 March of 2005. Result: The heparin group was significantly different from the normal saline group in CVCs' occlusion. The normal saline group offered a much longer survival duration of CVCs' patency than the heparin group. Potential bleeding signs (PT, aPTT) had no significant differences. In multivariate analysis, 0.9% normal saline (hazard ratio 0.50), chemo port (hazard ratio 3.38), and no administration of TPN (hazard ratio 0.25) were the significant factors for occlusion of CVCs. Conclusion: For maintaining the patency of CVCs, 0.9% normal saline flushing are expected to be effective in reducing drug incompatibilities, lessening the bleeding tendency and improving cost effectiveness .

The purpose of the present study was to demonstrate the important role of music in the treatment programme for autistic children, through a review of the literature. It has been shown that autistic children who do not generally respond to verbal communication respond to music which is partially non-verbal. The followings were suggested in the study: 1. Music has the soothing effect on the emotionally disturbed children. , 2. Autistic children generally positively respond to music. Therefore, music can be used as a reinforcer in teaching. 3. Music in a rondo form can be applied to teach various skills activities. Teaching sign language for the children through the Orff's schulwerk method was introduced as an example. and, 4. Music may be utilized to decrease stereotyped behaviors of autistic children. Thus, the rhythmic body movements of autistic children (stereotypes) may be expressed in a music session as a form of dance or physical exercise to the extend that the children get the similar effect of jogging which is known to have decremental effect on the behaviors.

A Moving-Belt Type Electrostatic Precipitator (MBEP) proposed by one of authers has been improved by introducing systematic control concept for the diesel soot particulates from diesel engine exhaust. The proto type MBEP was designed without helping of any precharger or precoagulator of the soot particles, and so it is too large for equipping to the vehicles. The improved one is designed as a systematic control device consisted of a precharger and a MBEP. This systematization makes it possible miniaturizing the size of MBEP without any drop of its collection performance by enhancing the corona field intensity and current density in the collection space concurrently obtained by reducing the interelectrode spacing of corona electrode to collection electrode. As a result, the collection efficiency of present MBEP system, which is reduced by ca. 1/2 in volume to the proto type MBEP, amounts to 82% at the gas velocity of 1.0m/s (this nearly equals to the gas exhaust of a 2000 cc diesel powered vehicle) and gas temperature of ca. 50℃ for the simulated soot particles ranged in size from 0.005μm (mass median diam is 1.0 μm). The collection efficiency of the improved MBEP system of 82% is higher enough to the US EPA regulation limit of 70% of the year of 1985 for the diesel powered light-duty trucks and passenger cars.

Since the reports on the effect of stimulants in controlling motor restlessness, inattention and distractibility, efforts have been made to elucidate the mechanism of action of the stimulants, and pathophysiology of the attention deficit hyperactivity disorder. This review has attempted to summarize biological findings on attention deficit hyperactivity disorder, from the fields of neuropharmacology and neuroanatomy. Most of the studies demonstrated that catecholamine function and its modulation are very probably involved at some level in the pathogenesis and treatment of this disorder. Reports on several neuroanatomical lesions also have implications for the catelcholamine hypothesis of the disorder. Further studies focusing on the response to stimulants and physiological studies using brain imaging technology will provide more comprehensive model of the pathophysiology of the attention deficit hyperactivity disorder.

CAD/CAM 세라믹 인레이로 수복한 치아의 응력분포에 관한 유한요소법적 연구

송보경,엄정문 대한치과보존학회 2001 Restorative Dentistry & Endodontics Vol.26 No.6

When restoring a tooth, the dentist tries to choose the ideal material for existing situation. One criterion that is considered is its suitability for restoring coronal strength. As more tooth structure is removed, the cusps are weakened and susceptible to fracture. Further, this increased deformation may cause the formation of intermittent gaps at the margin between the hard tissue and the restoration, facilitating marginal leakage. The improvements in ceramic materials now make it possible for alternatives to amalgams, composites, and cast metal to be offered for posterior teeth. Of the materials used, ceramics most closely approximates the properties of enamel. The introduction of computer-aided design/computer-aided manufacture(CAD/CAM) systems to restorative dentistry represents a major technological breakthrough. It is possible to design and fabricate ceramic restorations at a single appointment. Additionally, CAD/CAM systems eliminate certain errors and inaccuracies that are inherent to the indirect method and provide an esthetic restoration. The aim of this investigation was to study the loading characteristics of CAD/CAM ceramic inlay and to compare the stress distribution and displacement associated with different designs of cavity(the isthmus width and cavity depth) . A human maxillary left first premolar was prepared with standard mesio-occlusal cavity preparation, as recommended by the manufacturer. Ceramic Inlay was fabricated with CEREC 2 CAD/CIM equipment and cemented into the prepared cavity. Three dimensional model was made by the serial photographic method. The cavity width was varied 1/3, 1/2 and 1/3 of intercuspal distance between buccal and lingual cusp tip. The cavity depth was varied 1.5mm and 2.3mm. So six models were constructed to simulate six conditions. A point load of 500N was applied vertically onto the first node of the lingual slope from the buccal cusp tip. The stress distribution and displacement were solved using ANSYS finite element program(Swanson Analysis System) . The results were as follows ; 1.The displacement occurred buccal, distal and cervical direction from the buccal cusp. In case of the deep cavity, the displacement decreased and with the increase of the cavity width, it increased. 2.In ceramic inlay, the stress decreased in the deep cavity and it increased with the increase of the cavity width. The stress in composite resin cement was less than in ceramic inlay, therefore the stress propagation was blocked by composite resin cement. 3.As the width of cavity increased, the stress spread and increased at the buccal cavosurface margin, so the possibility of crack increased. In case of the deep cavity, the stress decreased at the distal margin of cavity. 4.With the increase of cavity width and depth, the stress on the facio-pulpal line angle increased. In case of narrow cavity width, stress increased on the facio-gingival line angle. Therefore the possibility of crack increased. 5.In case of the shallow cavity, the direction of crack was cervico-lingual on the facio-pulpal line angle. In case of the deep cavity, the direction of crack was cervico-buccal on the facio-pulpal line angle and move vertically with the increase of the cavity width. Key words : Finite element stress analysis, CAD/CAM ceramic inlay, Cavity width, Cavity depth, Stress, Displacement

주의력결핍 과잉행동장애 아동의 주의집중력의 특성 : 시각 및 청각 TOVA와 지능검사 결과를 중심으로

최보문,이방락 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.5

연구목적: 주의집중력의 장애를 주 호소로 내원한 임상 아동들 중에서 주의력 결핍 과잉행동 장애로 진단된 아동과 기타 임상집단 아동의 주의력이 지능지수와 시각및 청가 TOVA에서 어떻게 나타나는지 알아보고자 본 연구를 시도하였다. 방법: 주의집중력의 장애를 주 호소로 내원한 47명의 환아중, 주의력결핍 과잉행동 장애로 진단된 24명의 아동과 그 외의 질환으로 진단된 23명의 아동을 대상으로 하였다. 두 대상 집단의 지능검사를 변인으로 하여 시각및 청각 TOVA의 결과를 비교하였다. 결과: ADHD 집단의 아동은 non-ADHD 아동과 비교하여 볼 때 전체 지능지수, 언어성 및 동작성 지능에서 모두 낮았으며, 공통성과 어휘를 제외한 전 소항목에서 특히 의의있게 낮은 것으로 나타났다. 진단 상태에 따른 TOVA결과에서, ADHA 아동의 79.1%가 시각 TOVA에 의하여, 100%가 청각 TOVA에 의하여 장애가 있다고 해석되었다. 시각 및 청각 TOVA가 ADHD와 non-ADHD를 정확하게 진단해낸 비율은 시각-TOVA의 경우 67.8%, 청각-TOVA의 경우 60.8%이었다. 시각 TOVA 중 오경보 오류 변인에서 ADHD 아동이 총 시간당 의의있게 수행이 저하되어 있었으며 특히 전반 1/2 에서 더 수행이 떨어지는 것으로 나타났다. 청각 TOVA에서는 ADHD아동의 누락오류 변인의 후반 1/2 및 총 시간당 수행에서 모두 수행이 떨어지는 것으로 나타났다. 결론: 주의집중력의 장애를 호소하는 임상 아동 중에서 주의력 결핍 과잉행동장애로 진단된 아동은 다른 임상진단 아동에 비하여, 지능검사상 기호쓰기, 숫자, 이해의 소항목에서 의의있게 수행이 저하되어 있었고, TOVA에서는 시각TOVA의 오경보 오류 변인의 전반 1/2 및 총시간에서, 청각 TOVA의 경우 누락 오류변인의 후반 1/2 및 총시간에서 수행이 저하되어 있었다. 지능검사 결과상의 세가지 항목과 시각 및 청각 TOVA의 누락오류변인이 충동조절 능력을 반영한다고 할 때, ADHD 아동은 임상집단 아동에 비하여 충동조절의 장애가 뚜렷한 것임을 시사하고 있다. 중심단어:주의집중력·TOVA-청각·충동통제. Objectives: The purpose of the study was to evaluate how the visual and auditory TOVA along with the IQ scores can differentiate the attentional deficit, both in children with ADHD only and in children with clinical diagnoses other than ADHD. Method: Forty seven children were divided into two groups, who were diagnosed as ADHD only and non-ADHD. One child & adolescent psychiatrist and one clinical psy-chologist were involved in the diagnostic process. Psychological tests battery including TOVA-visual and auditory was applied to all children. The raw data from the results was analyzed statisically by ANCOVA. Results: ADHD children were significantly scored lower in total IQ scores, as well as in all the subscores of IQ tests except similarities and vocabulary, though all of the children were classified within normal limit in terms of total IQ scores. Among the subscores of the IQ tests, the scores of arithmatic, digit span and coding were more significantly lower in ADHD children were significantly more impaired in performance in the variables of commission for the first half & total with visual TOVA, in the variables of commission for the second half & total with auditory TOVA. Conclusion: The ADHD children could be differentiated by the variables of both com-mission and variability of auditory TOVA. Assuming that the subscores of arithmatic, digit span and coding in the IQ test, as well as the variables of commission and variability of auditory TOVA reflect the ability of impulse control, the results suggest that the ADHD children would be more impaired in impulse-control than the children diagnosed other than ADHD. KEY WORDS: ADHD·TOVA-auditory·Impulse-control.
