Fracture of the tibial shaft is the most common among the long bone fractures, and it is difficult to treat because of a high incidence of delayed union, nonunion and malunion. Interlocking Intramedullary mailing is considered to be valuable method in treating long bone fracture such as tibial fracture these days because it enables rigid fixation, early joint motion exercise and weight bearing. Between April 1993 and March 1997, we treated 63 cases of tibia fractures with interlocking intramedullary nailing. The results were as follows: 1. Among the 63 cases, 51 cases were closed fractures and 12 cases were open fractures. 2. Static interlocking nailing was done in all cases and dynamization was done in 7 cases in postoperative 13 weeks. 3. Average union time was 19.9 weeks, 19 weeks with closed tibia fracture and 2.4 weeks with open tibia fracture. According to fracture site, 22 weeks with proximal tibia fracture, 19.2 weeks with mid-tibia fracture and 21.4 weeks with distal tibia fracture. According to the Winquist-Hansen classification, Type I was 19.8 weeks, Type Ⅱ was 20.4 weeks, Type Ⅲ was 22 weeks and Type Ⅳ was 26 weeks. 4. Weight bearing was started at the time of subsidence of pain and tenderness of the fracture site, 11.5 weeks with closed fracture and 12.3 weeks with open fracture. 5. According to the functional result of Klemm and Borner, 44 cases were excellent, 9 cases were good, 7 cases were fair and 3 cases were poor.

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.

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.

본 연구의 목적은 표면처리가 기존의 레진과 새로운 레진 사이의 전단결합강도에 미치는 영향을 평가하는 것이다. 준비된 레진 시편을 6군으로 임의로 배분하여 각각의 표면처리를 한 후 수리용 레진을 축조하였다. 일주일간 보관 후 전단결합강도를 측정하였고 일원분산 분석법으로 통계처리하여 다음과 같은 결과를 얻었다. 1. 3군과 4군(air abrasion)은 1군(산부식)에 비해 전단결합강도가 유의하게 높게 나타났다(p<0.005). 5군과 6군(diamond bur)은 1군(산부식)에 비해 높은 전단결합강도를 나타냈으나 통계적으로 유의하지 않았다(p<0.005). 2. 2군(자가부식 접착제)은 1군(산부식)에 비해 전단결합강도가 낮게 나타났으나 유의한 차이는 없었다(p<0.005). 3. 3군(air abrasion)과 4군(air abrasion +산부식)에서 전단결합강도의 차이는 유의하지 않았다(p<0.005). 4. 5군(diamond bur)과 6군(diamond bur+산부식)에서 전단결합강도의 차이는 유의하지 않았다(p<0.005). 결론적으로,복합레진의 수리 시 air abrasion으로 표면처리를 했을 때의 결합강도가 가장 높았고,산부식 방법과 처리여부는 수리강도에 유의한 영향을 미치지 않았다. The purpose of this study was to evaluate the effect of surface treatment on the shear bond strength between new and old composite resin. The prepared resin specimens were separated 6 groups, and each group then received a different surface treatment. Then the repair material was added. Shear bond strengths for repair were measured after 7 days and the results were analyzed by using one way ANOVA. The results were as follows ; 1. Group 3, 4(air abrasion) showed significantly higher shear bond strength than Group l (phosphoric acid)(p<0.05). Group 5, 6(diamond bur) showed higher bond strength than Group l(phosphoric acid) but not significantly different(p<0.05). 2. Group 2(self-etching adhesive) showed lower shear bond strength than Group 1 (phosphoric acid) but not significantly different (p<0.05). 3. There was no statistically significant difference between Group 3 (air abrasion) and Group 4(air abrasion + etching). 4. There was no statistically significant difference between Group 5(diamond bur) and Group 6(diamond bur+etching). In conclusion, the surface treatment with air abrasion resulted in higher repair bond strength than other methods. Repair bond strength was not significantly affected by acid etching.

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.

Many studies have been attempted to overcome the problems of paclitaxel related to the extremely low aqueous solubility of paclitaxel and the unexpected side-effects caused by Cremophor® EL in a commerical paclitaxel formulation. Taxol®. In order to formulate a new delivery system suitable for intravenous administration without toxic excipients, in this study, paclitaxel was incorporated into solid lipid nanoparticles (Px-SLN) by hot homogenization technique using a microfluidizer. Particle size and zeta potential were measured by a Zetasizer. In vitro drug release experiment was performed by a dialysis diffusion method. Each Px-SLN or Taxol® was intravenously administered to the male Sprague-Dawley rats at a dose of 5㎎/㎏ as paclitaxel. Blood samples were deproteinated with acetonitrile and assayed for paclitaxel by the validated HPLC/MS/MS method. Mean particle size and zeta potential were measured as 72.1 nm(<Polydispersity 0.3) and -41.5 mV, respectively. The content of paclitaxel in SLN was 1.42 ㎎/ml and the drug loading efficiency was 71.2±4.3%. The AUC_(t) of Px-SLN was 3.4-fold greater than that of Taxol^(?). The Px-SLN might be a promising candidate for an alternative formulation for the parenteral delivery of paclitaxel.

Objectives : This study was designed to evaluate the relationship between quality of life (QOL) and psycho-socio-spiritual characteristics in male patients with alcohol dependence. Methods : The sample consisted of 109 men with alcohol dependence defined by DSM-IV criteria. We assessed QOL by the WHO QOL assessment instrument-BREF (WHOQOL) and SmithKline Beecham QOL (SBQOL). Sociodemographic and alcohol related data were collected, and 7 questionnaires were administered : MAST, BDI, STAI, Drinker Inventory of Consequences (DrInC), Scale of Social Support (SSS), Religious Beliefs and Behaviors (RBB) and Spiritual Well-being Scale (SWBS). The correlations between each QOL score and other variables were examined, and stepwise multiple regression analysis was performed. Results : The WHOQOL score positively correlated with education level, SSS (support) and RBB and negatively correlated with MAST, DrInC, BDI, STAI (trait) and SSS (conflict) scores. In stepwise regression analysis, the scores on the STAl and BDI contributed to the score on the WHOOOL. The SBQOL score correlated with the income level, and negatively correlated with BDI and STAI score. STAI score was a weak predictor of SBQOL score. Conclusion : The significant predictors of QOL in patients with alcohol dependence were psychological factors such as anxiety and depression.
