Seo, Mi-Young,Kim, Hee-Seung,Kim, Ik-Jin The Korean Ceramic Society 2006 한국세라믹학회지 Vol.43 No.8

The effects of $Cr_2O_3$ on the microstructural evolution and mechanical properties of $Al_2O_3$ polycrystalline were investigated. The microstructure of $Al_2O_3-Cr_2O_3$ composites (ruby) was carefully controlled in order to obtain dense and fine-grained ceramics, thereby improving their properties and reliability with respect to numerous applications related to semiconductor bonding technology. Ruby composites were produced by Ceramic Injection Molding (CIM) technology. Room temperature strength, hardness, Young's modulus and toughness were determined, as well as surface strengthening induced by thermal treatment and production of a fine-grained homogenous microstructure.

Necrotizing pancreatitis develops in about 10-20% of patients with acute pancreatitis, and pancreatic abscesses develop in 3% of them. The mortality of pancreatic abscess has been reported up to 40% in one study. Recently, there are several reports that show good results with n on-surgical therapy, such as percutaneous drainage and endoscopic drainage, but if the non-surgical drainage fails, surgical therapy are recommended. However, there is no definite therapeutic method which is suggested yet so far after the failure of the surgical drainage. So we report the case in which we experienced successful treatment of pancreatic abscess by endoscopic removal of necrotic tissue through the gastrocystostomy, after the failure of the surgical debridement and internal drainage through gastrocystostomy.

본 연구는 유치원 기본과정과 방과후과정에 따른 만3세 유아의 대인문제해결능력과 친사회적 행동에 어떤 차이가 있는지를 알아보는데 연구의 목적을 두었다. 연구대상은 전북에 소재한 유치원에 재원 중인 만3세 유아 201명으로 유치원 운영시간에 따라 기본과정 유아 93명, 방과후과정 108명이다. 연구도구는 전정연(2002)이 수정보완하여 제작한 대인문제해결사고 검사도구와 김영옥(2003)의 친사회적행동 검사 도구를 간편형 척도로 재구성한 서소정(2006)의 검사도구를 사용하였다. 자료분석은 SPSS 21버전을 사용하여 연구대상의 일반적인 배경의 빈도와 백분율을 산출 후, t-test를 실시하였다. 본 연구결과는 다음과 같다. 첫째, 대인문제해결능력은 기본과정 유아들이 방과후과정 유아들보다 높은 것으로 나타났고, 하위영역의 결과예측 사고능력에서 기본과정 유아들이 방과후과정 유아들보다 높게 나타났다. 둘째, 친사회적 행동은 교육과정에 따라 유의미한 차이가 나타나지 않았으나, 기본과정 유아들이 방과후과정 유아들보다 친사회적 행동 중 감정이입과 조절하기를 많이 하는 것으로 나타났다. The purpose of this study is to indicate if there are any differences between interpersonal problem solving abilities and prosocial behavior of 3-year-old children based on basic education course and after-school course. The subjects of this study are 201 3-year-old kindergarten children from Jeonbuk, 93 children from basic education course and 108 after-school course based on operating hours. Interpersonal problem solving ability test method by Jeong-Yeon Jeon(2002) and the simplified reconstructed test method by So-Jeong Seo(2006) modified from prosocial behavior test method originally created by Young-Ok Kim(2003) were used. SPSS version 21 were used to analyze by calculating frequency on general background of the subjects and percentage, and then t-test was performed. The results are as follows. First, the basic education course infants have higher interpersonal problem-solving skills than the after-school course children, also the basic education course infants have indicated higher subregion predicted thinking level than the after-school course children. Second, prosocial behavior did not appear significant differences depending on the courses, however the basic education course children showed having a lot more inner-empathy and emotion control among prosocial behaviors than children of after-school course.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

본 연구는 브라켓 간접부착술식시 치면과 레진 베이스의 간격 및 접착제에 따른 전단결합강도를 비교함으로써 브라켓 간접부착의 접착제로서 호제(paste)형 레진 병용의 타당성 여부를 평가해보고자 시행되었다. 소의 하악 중절치 120개를 실험재료로 하여 대조군의 경우 접착제로 실런트만을 사용하는 반면 실험군의 경우 실런트와 호제형 레진을 병용하여, 치면과 레진 베이스 간의 간격이 0.0, 0.2, 또는 0.4 mm가 되도록 접착한 다음 만능물성 시험기를 이용하여 각 시편의 전단결합강도를 측정하고 비교하여 다음의 결과를 얻었다. 1.치면과 레진 베이스 간의 간격이 멀어질수록 두 군 모두에서 전단결합강도가 감소하는 것으로 나타났다. 2.치면과 레진 베이스 간의 간격이 0.0 mm인 경우 양 군 간의 전단결합강도의 차이는 나타나지 않았다. 3.치면과 레진 베이스 간의 간격이 0.2, 0.4 mm인 경우 실런트와 함께 호제형 레진을 병용한 경우의 전단결합강도가 실런트만 사용한 경우에 비하여 통계적으로 유의하게 높게 나타났다. 이상의 연구결과는 브라켓 간접부착술식시 치면과 레진 베이스 간의 간격이 의심될 경우 브라켓 간접부착의 접착제로서 실런트만 단독 사용하는 것보다 호제형 레진을 병용하는 것이 유리함을 시사하였다. (주요 단어 : 간접부착술식, 전단결합강도, 레진베이스, 접착제) The purpose of this study was to evaluate the feasibility of the combined use of paste resin with sealant as an adhesive of the indirect bonding. The resin bases made of light-cured resin were bonded to the bovine incisors at a distance of 0.0, 0.2 or 0.4 mm using the sealant only or the mixture of sealant and paste resin. Bond strength of each group was measured using universal testing machine. The results were as follows : 1.The bond strength was reduced in both groups as the distance between enamel surface and resin base increased. 2.The bond strength showed no statistical difference between two groups in case the distance between enamel surface and resin base was 0.0 mm. 3.In case the distance between enamel surface and resin base was 0.2 or 0.4 mm, the sealant with paste resin group showed significantly higher bond strength than the sealant only group. The results of the present study indicate that the use of paste resin with sealant may be desirable as an adhesive in indirect bonding, particularly in case a gap is suspected between enamel surface and resin base. ※Key words : Indirect bonding, Bond strength, Adhesive, Resin base
