We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

Purpose : To find the cause of root curvature by use of panoramic and lateral cephalometric radiograph. Materials and Methods : Twenty six 1st graders whose mandibular 1st molars just emerged into the mouth were selected. Panoramic and lateral cephalometric radiograph were taken at grade 1 and 6, longitudinally. In cephalometric radio graph, mandibular plane angle, ramus-occlusal plane angle, gonial angle, and gonion-gnathion distance (Go-Gn distance) were measured. In panoramic radio graph, elongated root length and root angle were measured by means of digital subtraction radiography. Occlusal plane-tooth axis angle was measured, too. Pearson correlations were used to evaluate the relationships between root curvature and elongated length and longitudinal variations of all variables. Multiple regression equation using related variables was computed. Results : The Pearson correlation coefficient between curved angle and longitudinal variations of occlusal plane-tooth axis angle and ramus-occlusal plane angle was 0.350 and 0.401, respectively (p<0.05). There was no significant correlation between elongated root length and longitudinal variations of all variables. The resulting regression equation was Y=10.209+0.208X_(1)+0.745X_(2) (Y: root angle, X_(1): variation of occlusal plane-tooth axis angle, X_(2): variation of ramus-occlusal plane angle). Conclusion: It was suspected that the reasons of root curvature were change of tooth axis caused by contact with 2nd deciduous tooth and amount of mesial and superior movement related to change of occlusal plane.

Hypereosinophilic syndrome is characterized by persistent blood eosinophilia of 1,500/ul or more in the absence of known causes and multiorgan dysfunction by eosinophil-related tissue damage. In Korea, some cases of hypereosinophilic syndrome with hepatic involvement have been described with prolonged benign clinical courses. Most of them were diffuse or multifocal lesions in imaging studies, and a few case presenting as a single mass has been described. Here we report a case of hypereosinophilic syndrome with hepatic involvement in a 65-year-old man who presented with multifocal mass lesions. By abdominal US and CT scan, multiple, ill-defined nodules were detected in throughout the liver. Liver biopsy revealed severe eosinophilic hepatitis, suggestive of hypereosinophilic syndrome. Hepatic mass lesions improved after steroid administration for several weeks.

Purpose : To compare the size of the masseter and lateral pterygoid muscle between the affected and the unaffected side of the patients who have the chief complaints of the mandibular asymmetry. Materials and Methods : Twenty two patients (male: 4, female: 18, average age: 21.3 year-old) were radiographed using posterior-anterior (P-A) cephalography and computed tomography (CT). On P-A cephalography, the degree of deviation was determined by the distance from the mentum to the vertical reference line through the crista galli and the anterior nasal spine. On the scanned tracing papers of the maximum cross-sectional area of the masseter and lateral pterygoid muscle using axial CT images, the pixel number was measured. The ratio of the affected : unaffected sides were obtained. For the masseter and lateral pterygoid muscle, the relationship between the muscular volume and degree of skeletal hypoplasia was studied. Results : The half cases showed no skeletal asymmetry. The lateral pterygoid muscle of the affected side was larger significantly than unaffected side (p<0.05). However, there was no significant difference between two sides in the cases of skeletal asymmetry. There was only significant difference in the cases without skeletal asymmetry (p<0.05). Conclusions : To some extent, the slight mandibular hypoplasia could affect the growth of some masticatory muscles.

Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.

Since our coutry has in sufficient natural resources, and water covers about 70% of the earth's surface, we must take advantage of our country being a peninsula, and internationalize by marine transportation. However, fuel costs are high, because fossil fuel deposits are limited and oil producting countries are closely banded together. Also, fuel emissions pollute the air throughout the world. Pollution levels for specific gases include 2% for CO2, 4% for SOx, and 7% for NOx. By the way, nuclear power is suitable as a high output power source due to its low cost and its use for powering ships is profitable because of its light weight and small volume. Also, it is most suitable as a power source in water, because it can be used for long term operations, and because oxygen is not necessary for combustion. In the future, if the safety of the marine reactor is made sure by its simplicity and technical development for automation. nuclear power will prove to be the means for future growth in marine transportation. It call be used to power vessels used as ice breakers, and can also be used for deep sea operations, especially submarines used for investigation and resource development. Therefore, I want to study the characteristics of the marine reactor compared with the power reactor, because marine reactor can be used in narrow space and are affected by ocean states. The contents I want to study are as follows. (1) Passive high safety (2) Suitability for various loads (3) Pursuit of small size

Purpose: The purpose of this study was to calculate the size and CT number of both normal parotid and submandibular gland, and evaluate their relation to sex, age and obesity using computed tomography. Materials and Methods: The computed tomography was performed parallel to the Frankfurt plane in 46 subjects with healthy salivary gland. The subjects were divided into the three groups(young, middle, old) according to their ages. The size of salivary gland was determined as maximum cross-sectional area and the CT number of salivary gland was determined as the mean CT number of three ROI's. The body mass index was calculated from weight and height. Results: The mean maximum cross-sectional area was 7.79(±1.25) ㎠ on parotid gland and 4.12(±0.83) ㎠ on submandibular gland. The mean CT number was -4.43(±23.87) HU on parotid gland and 50.01(±15.63) HU on submandibular gland. There was decreasing pattern of the maximum cross-sectional area of submandibular gland and the CT number of both parotid and submandibular gland according to age(p<0.50). As the body mass index increased, the maximum cross-sectional area of parotid gland increased and CT number of both parotid and submandibular gland decreased(p<0.05). The maximum cross-sectional area of submandibular gland in male was larger than that in female(p<0.05). As the maximum cross-sectional area and CT number of left salivary gland increased, those of right gland increased(p<0.05). Conclusion: Intra-individual differences in salivary gland size and CT number is considered in the age and individual obesity.(J Korean Oral Maxillofac Radiol 1999:29:207-219)

인터넷 신문의 그래픽 인터페이스 구조에 관한 연구 : 신문사 레이아웃 중심으로 centering on the newspaper companies' layouts

최진선,장순석 동덕여자대학교 디자인연구소 2002 디자인포럼21 Vol.5 No.-

본 논문에서는 정보전달매체로서의 효율성에 초점을 맞춰 인터넷 신문에 대한 디자인 기준들을 제안하고 이에 따른 주요 인터넷 신문 디자인에 대한 비교 분석을 함으로써 현 인터넷 신문 디자인의 문제점 및 개선되어야 할 방향을 모색하는데 목적이 있다. 인터넷 신문은 그래픽을 정보전달의 표현수단으로 사용하는 GUI이다. 매체가 다르다고 해서 그래픽 디자인의 기준이 변하는 것이 아니며, 새로운 인터페이스의 차이점을 파악하고 이에 가장 적합한 방식으로 정보를 시각화시켜 전달함으로써 정보이용의 효율성을 극대화시켜야 한다. 특히 시각디자인 적인 면에서의 사용자 인터페이스 측면에서 정보전달이 용이한지에 중점을 두었는데, 이러한 기준으로 현재 운영되고 있는 국내?외 인터넷 신문들의 디자인을 분석해 본 결과, 국내의 온라인 신문 사이트들은 대부분 몇 가지 공통된 특징을 가지고 있었다. 엄청난 정보의 제공을 위해서 공간의 구성을 비효율적으로 할 뿐만 아니라 배너 광고 등의 부수적인 요소에 현란한 플래시 기법을 사용함으로써 독이성을 떨어뜨려 사용자의 입장을 충분히 배려한 편안한 컨텐츠의 구성이 아쉬웠다. 또한 각 신문마다 오프라인에서 갖고 있는 자신들의 특성을 염두에 두지 않고 천편일률적인 구조로 사이트를 운영하고 있다는 점이다. 물론 구성에서 약간의 차이는 있지만, 디자인적인 조정이 미흡하다는 것이다. 인터넷 신문 디자인은 화려한 그래픽의 제작에 대한 것이 아니라, 사용자의 입장에서 효율적인 네비게이션을 고려하여 인터페이스 요소들을 이해하고 보다 적합하게 제시하는 것이다. 계속적으로 성장하고 변모하고 있는 인터넷 신문 디자인을 위해서 현 인터넷 신문 디자인을 분석하고 개선점을 파악하는 것은 의의가 있는 것으로 앞으로의 인터넷 신문 디자인 방향 모색에 도움이 될 것이다. The purposes of this study is to propose the criteria to design internet newspapers that are focused on their efficiencies as information transferring media, to compare and analyze the major internet newspapers' designs, to identify the problems of current internet newspapers' designs, and to explore the direction for their improvements. An internet newspaper is a GUI(Graphic User Interface) which uses graphic as a tool to express the transferred informations. No matter what is the selected medium, the criteria of graphic design are not changed. And, it is necessary to maximize the efficiency of using information by understanding the difference of new interface and by visualizing and transferring in the most appropriate manners to it. Particularly, this study focused on whether information can be easily transferred in the aspect of visual design of user interface. The designs of domestic and foreign internet newspapers were analyzed by these criteria. It was found that most domestic online newspaper sites had several common characteristics. They organized spaces inefficiently to provide enormous informations. They used dizzy flash techniques on the incidental elements such as banner advertisement, which hampered easy reading. The researcher felt the lack of comfortable contents organization in which users could be cared. Additionally, it was found that all the researched newspaper companies operated monotonously structured web sites without thinking their own characteristics. Although there were some difference of organization, they lacked adjustments in design. In the design of internet newspaper, it is required not to produce splendid graphics but to understand and provide interface which is appropriate to users with consideration of efficient navigation. It is significant to analyze the designs of internet newspapers and to identify the required improvements for the continuously growing and changing internet newspapers' designs. It will be helpful to explore the future direction of internet newspapers' design.

이 연구는 교사교육의 국제화를 지향하는 사범대학 특성화 프로그램 개발을 위한 기초 조사 차원에서 2007학년도 1학기에 146명의 사범대학 학생들을 대상으로 전공 영어 강의에 대한 인식과 만족도 등에 대해 설문조사의 방법으로 이루어졌다. 학생들의 영어 능력에 대한 자기 평가 결과, 대부분의 학생들이 자신의 영어 능력이 영어 강의 수강에 부족하고, 영어 강의에 대한 심리적 부담이 크다는 반응을 나타냈다. 또 영어 강의가 한국어 강의에 비해 전공 지식을 쌓는 데 도움이 되었다는 반응은 이공계를 중심으로 한 기존의 연구 결과보다 상대적으로 낮게 나타나는데, 이는 사범대학 영어 강의의 운영과 관련하여 좀 더 다양하고도 효과적인 방안이 고려되어야 함을 시사한다. 영어 강의 수강 시 어려움을 묻는 질문에서 과제 발표하기, 질문하기, 보고서 작성하기의 순으로 어려움을 호소하고 있는데, 이 역시 영어 강의를 위해서는 전반적인 영어 표현 및 이해 능력 향상 이 전제되어야 하며 무엇보다도 말하기, 듣기의 구어 능력 신장이 우선되어야 함을 재확인해 준다. 영어 강의 개선안에 대한 의견으로는 평가 방법의 다양성 및 융통성 확대, 영어 강의 수강을 돕는 전공 교재의 개발, 영어 강의 내에서의 교수-학생 상호 작용 증대, 국제교류의 기회 확대 등의 순으로 높은 반응을 보였다. 이는 향후 사범대학 영어 강의와 관련한 프로그램 개발에 시사하는 바가 크다. 즉, 영어 강의 평가를 결과 중심의 평가뿐만 아니라 과정평가와 수행평가에 초점을 두고, 영어 표현이 어려운 복잡한 사고 과정이 요구되는 경우 제한적으로 국문 반응을 허용하는 방안도 고려할 만하다. 또한 학습자들에게 좀 더 상세화된 강의 교재를 제공하고, 온·오프라인을 모두 활용하여 교수와 학생의 상호작용을 활성화할 수 있는 방안을 적극적으로 탐색할 필요가 있다. 아울러 학생들이 실질적인 국제교류가 가능하도록 다양한 교류 방안 함께 구체적인 강좌 개설도 요구된다.
