Objectives: To assess macular function after vitrectomy and membrane removal in eyes with idiopathic epiretinal membrane by means of multifocal electroretinogram (mfERG). Methods: Visual acuity, macular thickness measured by optical coherence tomography (OCT), and mfERG recordings were achieved for 14 eyes of 14 patients with idiopathic epiretinal membrane. All exams were performed before epiretinal membrane surgery and 1, 3, and 6 months after surgery. The average retinal response density and implicit time of each local response were estimated as anatomic macular areas corresponding roughly to 5 rings. Preoperative and postoperative responses of visual acuity, macular thickness, and mfERG were compared. The correlations of the change of retinal response density, visual acuity, and macular thickness were analyzed. Results: There were no significant changes in amplitude and implicit time measured by mfERG before and after the surgery (p>O.05). There were no significant correlations between the changes of amplitude and implicit time and visual acuity and macular thickness. Conclusion: Changes in mfERG recordings were not useful for predicting clinical prognosis after epiretinal membrane surgery.

Purpose : To investigate the shape and size of normal sella turcica on cephalometric radiograms. Materials and Methods : Cephalometric radiograms of 200 orthodontic patients of age ranging 6-42 years were examined. All subjects were divided into 5 groups by age, the dimensional change of sella turcica was examined according to age, and the configurations of sella turcica floor, tuberculum sella, and anterior and posterior clinoid process were also observed. Results : The contours of sella turcica floor were flat type in 54% and concave type in 46%. The contours of tuberculum sella were right angle type in 55% and obtuse angle type in 44%; Acute angle type and plane type were very rare comprising 0.5%, 0.5% each. The configurations of anterior clinoid process were point type in 80% and round type In 20% of cases, and those of posterior clinoid processes were point type in 60% and round type in 40% of cases. The dimensional change of sella turcica according to age range had significantly positive linear trend to sella turcica length, height, and width until 25 years. After 26 years, no significant increase was found in sella turcica dimension. Especially, the sella turcica length had more proportional increase than that of sella turcica height and width. Conclusion : The results of this study revealed that the configuration of normal sella turcica was variable and the dimensional change of normal sella turcica had a linear tendency with age until 26 years.(Korean J Oral Maxillofac Radiol 2001;31:43-9)

최성욱,오진호,김승호 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.3

Background. According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug for the treatment of paroxysmal supraventricular tachycardia(PSVT). But adenosine is not used frequently in our country, despite currently proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment for PSVT. Materials and Methods. We prospectively reviewed charts of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The first group was given 6mg of adenosine initially , and another 12mg was given within 5minutes if first dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10minutes. The results were analyzed by Chi-square test and student- t method Results. In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two groups in frequency of side effects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. Conclusion. Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand sdenosine, as a safe and effective first line drug for PSVT.

The spontaneous ignition characteristics according to particle size of granulated activated carbon were observed at a constant ambient temperature. As the results of the experiments at the same sample size, the ignition induction time increased as the sample vessel size increased and the critical spontaneous ignition temperature decreased as the sample vessel size increased. As the sample particle size increased, the critical spontaneous ignition temperature decreased. Apparent activation energy of the sample calculated from the Frank-Kamentskii's thermal ignition theory was 37.73 ㎉/㏖.

본 연구는 행정 영역에 있어서 조직문화를 포함한 행정문학연구에 대한 다양한 접근과 연구주제들을 탐색해 보는데 조그마한 토대를 제공해 보고자 하는 목적을 가지고 첫째, 조직문화에 대한 개념적·유형적 다양성과 그에 따른 연구접근법들을 소개 및 고찰해 보고, 둘째, 이러한 고찰을 토대로 공공행정 영역에서 조직문화를 연구할 때 고려해야 할 쟁점들을 논의해 보았다. 먼저 기존 문헌에 대한 고찰로써 조직문화가 갖는 개념적 다양성과 문화적 차원에 따른 조직문화유형들을 보았고 연구접근법으로써 인식론상 '변수'로 문화를 취급하는 기능주의와 '은유'로 문화를 보는 해석(상징)주의를 살펴보고 이 둘 간의 대조 영역을 통해 구체적인 비교를 해 보았다. 그리고 최근 추세인 포스트모더니즘적 연구경향을 보았다. 마지막으로, 이러한 기존 문헌에 대한 고찰결과 도출되는 조직문화연구 영역의 쟁점으로 연구자의 문화개념에 대한 가정문제, 분석단위 및 문화 수준에 대한 가정문제, 조직문화유형론에 대한 과신문제, 연구접근법의 선택문제 등에 대해 논의하였다. This study aims at exploring the various approaches and research themes in relation to organizational culture in the field of public administration. For this purpose, first, several theoretical typologies are reviewed which summarize the various differences in the culture concept. Second, it's classified into three approaches generally acceptable in analyzing organizational culture : Functionalism in that culture is seen as one variable among several others ; Interpretivism or Symbolism, the view that organizations are culture as opposed to the functionalist notion that organizations have culture, in that the culture concept works as a root metaphor for understanding the human constructs and expressions in organizations; Post-modernistic trend in that ambiguity or fragmentation is emphasized. Finally, based on the above theoretical review, cultural debates and issues at the empirical level are discussed, which need to consider on the public sphere. Here are researcher's assumption of culture concept, a level or a unit of analysis, the overconfidence to cultural scales, and the selection of analytical framework are debated.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

For quantitative predictions of the metastable features and the compact expression of phase equilibria encountered in the extractive metallurgy of cadmium and zine, the calculations of stable and metastable equilibrium diagrams of the Cd-Zn system are made using the four parameter subregular solution model. Parameters of the thermodynamic functions are derived from the phase diagram data of "Bulletin of Alloy Phase Diagrams" and the enthalpy data of Wittig and Kleppa. Stable equilibrium diagram and thermodynamic quantities re-calculated from the optimized parameters agree with all the experimental data within the errors. Such metastable phase equilibria as the chemical spinodals, the locus of compositions and temperature where the Gibbs energies of the liquid and solid are equal(To), the metastable extensions of the solidus and liquidus curves, and metastable miscibility gaps. Excellent agreement of the calculated solvus boundary data with the experimental data is believed to provide a correct expectation of the metastable phase equilibria.

청소년의 속어 사용과 자아개념과의 관계

최성욱,강동철 木浦大學校 敎育硏究所 2004 교육연구 Vol.16/17 No.-

본 연구는 목포지역의 청소년을 대상으로 속어사용과 자아개념과의 관계를 밝혀보고자 하는데 그 목적이 있다. 일반적으로 청소년들이 사용하는 말은 오락적이고 해학적인 성격을 띠고 있는 것도 있지만, 매우 폭력적이고 저속한 속어의 성격을 띠고 있는 말이 많다. 이것은 학생들의 생각이 거칠어지고 저속해져 가고 있음을 나타내는 것으로 인성지도 면에서 보더라도 매우 심각한 형편이다. 언격은 인격이라는 말이 있는데 말을 들어보면 그 사람의 인격과 성격을 알 수 있고 심리 상태를 알 수 있다. 사람의 말은 전인격의 반영이기 때문에 우리는 말의 교육을 통하여 사고방식을 훈련하고 나아가서는 인격을 도야하는 데까지 이르러야 할 것이다. 본 논문을 통하여 청소년들의 언어실태를 파악하고 어떻게 지도할 것인지를 살펴보고자 한다. The aim of this report is to survey the interrelationship between adolescent's usage of slang and self-concept in Mok-po. Followings are the hypotheses of this report. First, how do boys' and girls' usage of slang emerge? Second, how does their self-concept emerge? Third, what is the relationship between adolescent's usage of slang and self-concept? To solve these hypotheses, I observed 248 male pupils in high school, and 222 female pupils in high school. Followings are the results. First, boys use slang more than girls. In particular, frequency related with sex was high. Second, there was no distinctive difference between boys and girls in self-concept. Third, other factors are not meaningful except social self-concept in between usage of slang and self-concept(p<.05). In contrast, there is no distinctive relationship among moral self-concept, personal one, domestic one and educational one. In this report, first, we can observe that adolescence's usage of slang is related with sex. This indicates that boys are interested in sex. Second, self-esteem between boys and girls is little different. This indicates a sense of value isn't much different between them. Finally, social self-concept which is only meaningful between usage of slang and self-concept indicates adolescence's psychological state is negative against social system and not to perceive it.
