It is often not certain whether the focal defect of renal cortex of Tc-99m Dimercaptosuccinic acid(DMSA) renal scan in patients with acute pyelonephritis means the cortical scar by previous inflammation or recent active inflammatory lesion. Gallium-67 citrate(Ga-67) also has been known to be accumulated at the active inflammatory lesion. In order to evaluate the usefulness of the Ga67 and Tc-99m DMSA renal scan in patients with acute pyelonephritis, we reviewed the results of both study and clinical findings. Nintecn patients with typical clinical findings of acute pyelonephritis and admitted to our institute from Jan. 1998 to Nov. 1998 were included in this study. Tc-99m DMSA and Ga-67 scan were performed mean 3.3 and 7.3 days after admission. Eleven of 19 patients (57.9%) showed abnormally increased focal renal uptake on the Gallium-67 citrate scan and 14 of 19 patients(73.7%) had a cortical defect on the kidneys in Tc-99m DMSA scan. Seven(36.8%) patients had an abnormality in both study. Seven(36.8%) patients had an abnormality only in Tc-99m DMSA scan and 4 (21.1%) patients had an abnormality only in Ga-67 scan. Of 7 patients who had an abnormality on both scan, 5 patients had. an abnormality at same region in both scan and 2 patients had an abnormality at the different sites on the kidneys. With the above results, we speculate that Ga-67 scan and Tc-99m DMSA scan play a complementary role in the patients with upper urinary tract infection.

Digital media was realized by two-dimensional design backup. But, digital medium decides form of architecture, and act as a design tool that can expand area of thinking. With such social change, investigate for digital architecture. And, wish to analyze design process of digital architecture and search the characteristics. Through comparison of digital and analogue, clear up that the digital world had complex and ambivalent attribute. Define digital design process as "Digital continuum" with characteristic of digital architecture and divided in 3-steps of concept - development - representation. Analyzed digital design process of Frank O, Ghery, Peter Eisenman and Greg Lynn on th assumption division. As a result, design concept is starting from three-dimensional thinking instead of existent two-dimensional thinking. And because general work of process was gone by digital media, "mass costomization" was possible. Also, it gave architect new role, Differ with former days, select various variables, should tuning and cording, and emphasize role as coordinator who must select the result. Digital is summoning very radical and epoch-making change in architecture. At center of these change, digital design process asks architect complex thinking and creative concept.

Diagram is applied and transformed in various ways. And it is indicated of the modern society that possess the characteristics of complex and non-conclusive by the architecture as a media. So, in this study searched the architectural design process of MVRDV how using the diagram in their work, and through their work find out the way that combined diagrams and the special quality of their project and constructed an architecture. As a result, we could get some spacial quality of diagram. 1) Diagram enables ambivalent analysis in various side, not analyze project institutively and uniformly. 2) It offers potential order and boundary as express factors that is not detected directly. 3) It specified the potential topology through the relations between individual -individual, individual-entire. 4) Diagram open the relations between architectural thought, process and result, and reduce the gaps of the theory, practice and criticism. 5) And have a possibility of the media that can multiplication thought. This study limited in MVRDV's architecture work and searched characteristic of diagram. But in future it is necessary to study about the method of using diagram and potential possibility of diagrams.

TiO_2-loaded mesoporous materials were prepared by sol-gel method. Mesoporous materials suppressed the phase transformation of TiO_2 from anatase to rutile and increased the bandgap of TiO_2 which was explained in terms of the quantum size effect. Several kinds of nano-sized TiO_2 with particle sizes of 5∼20 nm, were obtained through the removal of the mesoporous materials by etching in 2 M NaOH or the calcination under air condition. They showed good activites in the photocatalytic oxidation of 2-isopropyl-6-methyl-4-pyrimidinol.

This study will provide early effective intervention strategy through a predicting behavioral intention or behaviors of hypertension patients, and improve the compliance via early removal of barriers. Study subjects are new case of hypertension with above stage 2 by JNC-Ⅵ from first community survey including blood pressure measurement, sociodemographic questionnaires and physical examination in study region. Second survey was applied to the new case of hypertension(541 persons) for estimation of behavioral intention. Subject of this survey was 383 persons. Follow-up survey performed about 5 months later after regular telephone visiting by trained nurse previously. Final study subjects were 222 persons with above stage 2 hypertension by JNC-Ⅵ criteria. This results were as follows ; 1. State of hypertension management 18.9% of subjects managed with drug medication, 19.7% with exercise, 29.8% with quitting or reducing of smoking, 37.0% with quitting or reducing of alcohol. 2. Sociodemographic factors Drug medication was higher in old age, lower education level, and rural residents. Its difference is statistically significant. In gender difference, female was higher than male. In aspect of life style modification management, exercise rate was higher in male, high educational level, 5th and 4th decade age group, but it was not statistically significant. Reducing or quitting of smoking was higher in male, rural area residents, above high school educational level, but was not significant with the exception of habitation area. 3. Life style modification It was revealed statistically significant that male and rural area residents were higher in life style modification. In education level, contrary to the intention for life style modification, the lower education level is, the higher life style modification occurs. 4. Factors associated with intention The former or abstinence smoker and alcohol drinker revealed higher intention score than current in intention for life style modification. And the other variables were not statistically significant.

어린이의 치과치료시 약물에 의한 진정요법 사용에 대한 실태조사

안소연,최병재,곽지윤,강정완,이제호 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

진정요법은 소아치과에서 사용하는 보상, 속박, 체계적 탈감작법(말-시범-시행), 친밀감 같은 통상의 방법으로는 환자의 반응이 개선되지 않아 일반적인 치과치료가 불가능할 때 사용하는 행동조절법이다. 최근 국내에서도 진정요법을 이용하는 사례가 증가하는 추세이나 그 기준이나 방법들에 대한 연구는 매우 부족한 상태이다. 미국소아치과학회의 진정요법에 관한 기준이 있기는 하지만 국내의 상황이 미국과 다르므로 한국에서의 연구가 필요하다. 이에 저자는 국내에 거주하고 있는 소아치과의사들을 대상으로 국내 소아치과에서의 진정요법 현황에 대한 실태를 조사, 그 결과를 정리하여 향후 소아치과 임상에서의 진정요법에 대한 임상 기준을 정하는데 기여하고자 국내에 거주하고 있는 대한소아치과학회 회원 573명을 대상으로 진정요법 사용 실태에 관한 설문지를 발송하여 이 중 회신을 한 220명의 설문을 분석하여 다음의 결과를 얻었다. 1. 응답자의 약 66%가 진정요법을 사용하고 있다고 답했다. 진정요법에 관한 이전 연구 결과와 비교해 볼 때, 국내 소아치과에서 진정요법의 사용빈도가 증가하였다. 2. 진정요법으로 치료를 결정 하게 된 요인은 행동조절, 치료내용과 양, 보호자의 요구, 내원횟수, 전신질환의 순서이었다. 3. 진정요법으로 치료받는 환자의 연령은 만 3세가 가장 많았고, 만 4-5세, 만 2세 미만, 만 6-10세, 만 10세 이상의 순서로 조사되었다. 4. 진정요법 시 chloral hydrate는 60-70mg/kg, hydroxyzine은 10-40mg/kg(25mg/kg)을 사용하고 있었고, 경구 투여가 가장 선호하는 약물투여 경로였다. 5. 진정요법 시 사용하는 환자감시 방법은 피부나 손톱색 둥의 관찰을 포함한 환자 평가와 맥박 산소측정기(pulse oximeter)를 통한 환자감시를 선호하는 것으로 조사되었다. 6. 진정요법을 사용하고 있다고 응답한 사람의 약 56%에서 심폐소생술 교육을 받은 것으로 조사되었다. Sometimes the dentists encounter a child who can not be treated with traditional behavior management techniques (for example, reward, restraint, Tell-Show-Do, familialization). In such a case, the dentists use sedation technique. Recently, in Korea, the use of sedation by pediatric dentists is increased. But, the guideline and survey of sedation is very insufficient. Now, we need a survey of sedation practice in Korea. We carried out research on the actual condition about sedation with a questionaire to pediatric dentists in Korea. Followings are the conclusions 1. Sixty six percent of pediatric dentists use sedative agents in their practice. In this study, using sedation shows an increase as compared with the past. 2. Determinative factors of using sedation were orderly behavior management, number of visiting, guidian's opinion, amount of treatment, general condition. 3. Distribution of ages in patients sedated with agents was orderly 3 years, 4-5 years, under 2 years, 6-10 years, more than 10 years. 4. Particular sedative drugs were chloral hydrate 60-70mg/kg, hydroxyzine 10-40mg/kg(25mg/kg), and oral route was the most favorable route. 5. Observation of skin and nail color, pulse oximeter were the most frequently utillized monitoring method during sedation. 6. Only fifty six percent of pediatric dentists complete the cardiopulmonary resuscitation course.

하악 제1대구치 이소맹출의 치험례

소정원,이광희,라지영,안소연,김윤희,반재혁 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.1

Ectopic eruption is caused by an abnormal direction of eruptive path, most common in maxillary first molar, mandibular lateral incisor, and maxillary canine, and sometimes mandibular first molar. Ectopic eruption of first molar leads to abnormal root resorption of second deciduous molar, which, if left untreated, could cause premature loss of second deciduous molar; mesial tilting and rotation of first permanent molar; lack of space for eruption of second premolar; and occlusal problems. Therefore early treatment is advised when diagnosed as ectopic eruption. Treatment of ectopic eruption in the first permanent molar involves providing proper guidance for the direction of eruption using interproximal wedging and distal tipping methods while preserving second deciduous molar. This case report shows satisfactory results of the ectopic eruption of mandibular first molars in young patients who were treated with Humphrey appliance and Halterman appliance. 이소맹출은 치아가 비정상적인 위치로 맹출하는 경우를 말하며, 주로 상악 제1대구치, 하악 측절치, 상악 견치에서 발생하며 하악 제1대구치에서는 드물게 발생한다. 제1대구치의 이소맹출은 흔히 제2유구치의 비정상적인 치근흡수를 야기하며, 이를 방치하게 되면 제2유구치의 조기상실, 제1대구치의 근심경사 및 회전, 제2소구치의 맹출 공간 부족 및 교합문제 등을 야기하게 되므로 이소맹출로 진단될 경우 조기 치료가 추천된다. 이소맹출은 대개 통상적인 방사선검사를 통해 발견되나, 간혹 제2유구치의 치근흡수가 심할 경우 치수가 감염되어 동통을 야기하는 경우도 있다. 이소맹출의 치료는 제2유구치를 보존하면서 제1대구치의 맹출 방향을 바로 잡아 주는 것으로 크게 치간이개(interproximal wedging)와 원심경사이동(distal tipping)을 이용한 방법을 사용한다. 본 증례들은 하악 제1대구치의 이소맹출을 보이는 환아들로, Humphrey appliance와 Halterman appliance를 이용하여 양호한 치료 결과를 얻었기에 보고하는 바이다.

통합기관으로의 전이과정에서 장애유아가 갖추어야 할 중요 기술과 선결 요건들에 대한 분석 : 유아교사의 인식을 중심으로 Based on recognition of early childhood teachers

조윤경,이소현 국립특수교육원 2002 특수교육연구 Vol.9 No.2

유아특수교육의 주요 목적 중에 하나인 학령기 특수교육 의뢰의 최소화를 위해서 장애유아의 조기 통합이 강조되고 있다. 장애유아와 그 가족들이 가정 혹은 유아특수교육기관에서 통합기관으로 전이하는 과정에서 그들의 사전 준비와 원활한 전이를 위한 정보를 제공하기 위해서 전국 218명의 유아교사들에게 장애유아가 유아교육 기관에 통합하고 옮겨오는 전이 과정에서 필요한 중요 기술들이 무엇인지, 그리고 기술들의 발달과 함께 전이와 관련해서 고려해야 할 요소들은 어떤 내용인지에 대한 설문을 시행하였다. 설문 결과 유아교사들은 학급적용 기술과 사회성 기술을 인지 기술 보다 통합기관으로서의 성공적인 전이를 위해서 더 중요한 기술들로 인식하고 있었다. 통합 전이 시에 가장 선행되어야 하는 요건으로 유아교사 자신의 전문적 능력 향상과 통합에 대한 긍정적 인식 및 지원교사 체계의 확립 등이 제시되었다. 이러한 결과들에 대한 추후 대처 방안이 논의되었다. To minimize the referral of special education in school ages, the importance of early integration for young children with disabilities was suggested. This study was implemented to provide early childhood special teachers and families of young children with disabilities with the information to accomplish the successful transition to regular preschool program. Questionaries to know what the critical skills to transit from early childhood special education to early childhood education and the prerequisite elements to facilitate successful transition were carried out by 218 early childhood teachers who would take the major instructional role in integrated program. The results showed that early childhood teachers rated classroom-adaptive and social skills more important than cognitive skills. And they thought that it was tasks to solve immediately-the promoting their ability as educational professionals, developing positive perception about integration, and establishing the supportive personnel system. Based on these results, future suggestions were discussed.
