The purpose of this study was to compare the shaping time of two shaping methods and the leakage of three different obturation techniques. Ninty three canaled human molar teeth were used. which were randomly divided into two groups of forty teeth each and ten control teeth. After working length determination. the one group was prepared crowndown technique using rotary root canal instruments of GT rotary files .12/20, .10/20, .08/20 and .06/20 taper(Maillefer Instrument SA. Switzerland). The other group was instrumented with Gates Gildden burs(#1, #2 and #3) to coronal preparation and GT rotary files .08/20 and .06/20 taper to apical preparation. Shaping time was measured. After root canals were instrumented, they were divided to three subgroups and obturated as follows: Subgroup 1, obturated with single cone method : Subgroup 2, obturated with lateral condensation : Subgroup 3, obturated with continuous wave technique. Three subgroups were obturated using non-standardized gutta-percha cone(Diadent, Korea, 06 or .08 taper) and AH-26(Dentsply DeTrey, Germany) as a root canal cement. Ten unobturated teeth served as positive and negative controls. After immersion in 2% methylene blue solution for 1 month, the teeth were washed during 24h. The teeth were determineralized in 10% nitric aciid and dehydrated by immersion in 80, 90 and 100% ethyl alcohol. The teeth were finally cleared and stored in 100% methylsalicylate, and apical dye penetration was evaluated under stereomicroscope(Leica M420, LC, U.S.A) at (×) 8.75 magnification. Liner measurement of dye penetration was assessed with the use of digitalized image analysing system (analySIS, GmbH, Germany), The data were analysed statistically using independent T-test and Two-way ANOVA and Tukey test. The result were as follows: 1. In canal prepared with GT^Trotary file, shaphing time taked more than the group of using Gates Gildden drill to coronal preparation without statistical significant (p>0.05). 2. The group of single cone obturation using canal preparation of GT^TM rotary files showed significantly more apical leakage than those of lateral condensation and continuous wave technique regardless of shaping method (p<0.05). 3. The group of single cone obturation using canal preparation of GT^TM rotary files and Gates Gildden drill showed significantly more apical leakage than those of continuous wave technique regardless of shaping method (p<0.05). 4. Regardless of shaping method. The group of continuous wave obturation showed less apical leakage than those of lateral condensation without statistical significance (p>0.05). 5. The group of single cone obturation using canal preparation of GT^TM rotary files and Gates Gildden drill showed more apical leakage than the group of lateral condensation using sane shaping method without statistical significance (p>0.05).

Torsades de pointes is a form of polymorphic ventricular tachycardia that is associated with prolongation of the QT interval, characterized by QRS complexes of progressively changing amplitude and contour that seem to revolve around the isoelectric line. The most common cause of Torsades de pointes induced by antiarrhythmic agents, occupying in certain drugs or toxin, electrolyte disturbance, congenital QT prolongation syndrome. Cardiotoxicity terfenadine, in overdose a widely used, nonsedating antihistamine, has been reported. Case after administration of terfenadine and ketoconazole causing syncope and torsades de pointes have been reported in recommended dose. We report a case of QT prolongation with torsades de pointes after therapeutic administration of terfenadine, a long acting histamine H1 receptor antagonist, together with ketoconazole, an antifungal preparation. The patient is a 43-year-old female, who experienced palpitation, dizziness and syncopal episoders after coadministration of terfenadine and ketoconazole, for a fungal infection of the skin. The ECG showing typical episodes of torsades de pointes with QT prolongation. Magnesium sulfate was given, torsades de pointes did not recur. The patient was discharged with improved condition.

The prevalence rate of Social Phobia (Social anxiety disorder) varies among cultures and patient populations. Possible reasons for this differences are that the expression of social anxiety may differ according to cultures. It has been suggested that offensive type of social phobia (which is similar with taijin kyofusho ; a kind of culture-bound syndrome in DSM-Ⅳ) exist in east-asian countries, especially Korea and Japan, and it shares many common aspect with the western concept of social phobia. It is important to consider cultural influences of social phobia and understand various clinical presentations of this disorder. In this paper, the authors reviewed current diagnostic classification of diverse social phobia subtype and relationship among subtypes and also suggested the offensive type as a subtype of social phobia.

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.

Idiopathic thrombocytopenic purpura is a disease characterized by thrombocytopenia in peripheral blood with positive anti-platelet antibody titer, no splenomegaly, the presence of megakarocyte. The causes of idiopathic thrombocytopenic purpura were usually related to autoimmune disease, infection and drugs. A 46-years-old man was admitted for evaluation of abdominal mass. He has many cafe-au-lait spots and nodules in almost skin for 30 years. Several years ago, he palpated mass in Lt. inguinal area. hIe has known the abdominal mass after checking abdomen CT in local clinic and visited our hospital for evaluation of abdominal mass. At admission, laboratory tests showed hemoglobin 12.5 g/dL, hematocrit 38.4 %, WBC 5,460 /㎣ (neutrophil 64.5%, lymphocyte 21.7%, monocyte 4.1%, eosinophil 5.4%), reticulocyte 0.7%, Platelet 52,000 /㎣, total protein 6.51 g/dL, albumin 3.80 g/dL, alkaline pohsphatase 161 IU/L, AST 110.7 IU/L, ALT 64.9 IU/L, total bilirubin 0.44 ㎎/dL, BUN 18.4 ㎎/dL, creatinine 0.79 ㎎/dL. Peripheral blood smear showed normocytic normochromic anemia, thrombocytopenia. Bone marrow aspiration smear showed normoplastic myeloid and erythroid precursor. The bone marrow biopsy section shows normocellular marrow (35%) for his age and mildly increasing myeloid cell lineage. We have experienced a case of idiopathic thrombocytopenic purpura in a patient being in neurofibromatosis and therefore reporting it with documentary records. 저자들은 신경섬유종증 환자에서 특별한 원인을 발견할 수 없었음에도 특발성 혈소판 감소증이 발생한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

본 연구는 신입간호학생들의 직업선호도와 간호직업에 대한 평가를 알아보고자 조사되었다. 자료수집은 2018년 6월에서 10월까지 두 개 대학에서 편의표출로 시행되었다. 본 연구 결과, 간호학과 신입생들의 직업선호도 평가에서 ‘높은 임금’이 선호되었으며, 간호직업에 대한 평가에서는 ‘남을 도울 수 있는 직업’이 가장 높은 평가 점수를 보였다. 직업선호도와 간호직업 평가에서 모두 가장 낮은 점수를 보인 항목은 ‘창조하고 새로 만드는 것을 할 수 있는 직업’이었다. 간호학생과 학생들이 직업에 대한 이해를 충분히 할 수 있도록 다양한 탐색 방안을 마련하는 것이 필요하다 The purpose of this study was to investigate the occupational preference and evaluation of nursing job on new nursing students. Data collection was conducted at the two universities from June to October 2018 by convenience sampling. As a result, 'high wage' was preferred in the occupational preference. In the evaluation of nursing job, it was evaluated as 'job that can help others'. The lowest score item of both job preference and nursing job evaluation was 'job to create and to make new'. It is necessary to provide diverse approaches for nursing students to understand their profession.

The purpose of this study was to investigate motivation for major selection, major satisfaction and professionalism among nursing students. Data collection was conducted at the two universities from August to September 2019 by convenience sampling. As a result, personal motivation in major selection was positively correlated with major satisfaction and professionalism (r=0.703, p<0.001; r=0.379, p<0.001). In addition, major satisfaction scores and professional occupation scores were higher in the group with high personal motivation(t=5.955, p<0.001; t=2.903, p=0.004). Motivation for major selection can affect major satisfaction and professionalism. Therefore, it is necessary for students before major selection to have sufficient opportunities to search for majors. 본 연구는 간호학생들의 전공선택동기와 전공만족도, 전문직관에 대해 알아보고자 조사되었다. 자료수집은 2019년 8월에서 9월까지 두 개 대학에서 편의표출로 시행되었다. 본 연구 결과, 전공선택동기에서 개인적 동기는 전공만족도와 전문직업관과 양의 상관관계를 보였다(r=0.703, p<0.001; r=0.379, p<0.001). 또한 개인적 동기가 높은 집단에서 전공만족도 점수와 전문직업관 점수가 높게 나타났다(t=5.955, p<0.001; t=2.903, p=0.004). 전공선택동기는 전공만족도와 전문직관에 영향을 미칠 수 있다. 따라서 전공 선택전 학생들이 충분한 전공탐색의 기회를 가지는 것이 필요하다.
