Purpose: The purpose of this research was to evaluate the shear bond strength between zirconia core and veneer ceramic after surface treatment. Material and methods: Zirconia cores(N=40, n=10, $10mm{\times}10mm{\times}3mm$) were fabricated according to the manufacturers' instructions and ultrasonically cleaned. The veneering ceramics(thickness 3 mm) were built and fired onto the zirconia core materials. Four groups of specimens with different surface treatment were prepared. Group I: without any pre-treatment, Group II: treated with sandblasting, Group III: treated with liner, Group IV: treated with sandblasting and liner. The shear bond strength was tested in a universal testing machine. Data were compared with an ANOVA and $Scheff{\acute{e}}$ post hoc test(P=.05). Results: The shear bond strength of group VI was significantly higher than the other groups. Conclusion: Both mechanically and chemically treated simultaneously on zirconia core surface influenced the shear bond strength between the core and veneering ceramic in all-ceramic systems.

The area of this study consists of extrusive rocks and intrusive rocks which formed by igneous activity of 1ate cretaceous. Extrusive rocks are andesitic rhyolite, tuffeous rocks and rhyolite, whereas intrusive rocks are WeoIchulsan granite, quartz porphyry, felsite, breccia and dykes, which intruded above extrusive rocks. Metal ore deposits developed in this area are diseminated sulfide deposits distributed within prophylite and gold bearing quartz vein developed within andesitic rhyolite and rhyolite. Mineralization can be separated into three stages (Ⅰ,Ⅱ and Ⅲ). Each stage of minerals is pyrite, sphalerite in stage Ⅰ and pyrite, sphalerite, chalcopyrite, galena in stage Ⅱ and pyrite, arsenopyrite, sphalerite, chalcopyite, galena, pyrrhotite, etc. and minor electrum and alterated minerals, covellite, goethite, etc., in stage Ⅲ. Associated igneous rock influenced in mineralization of these deposits can be assumed the quartz porphyry. Classification of CIPW norm analysis of rocks distributed in this area is as follows; The variation trends of AFM triangular diagrams and the Differentiation Index (norm, Q+Or+Ab) versus oxides diagrams are similar to the Bulgugsa igneous rocks. Si0_2 versus Na_2O+K_2O diagram belongs to calc-alkali series. Homogenization temperature of fluid inclusions ranges from 110℃ to 140℃ of epithermal and from 160℃ to 300℃ of mesothermal and the size of fluid inclusions ranges from 0.0lmm to 0.15mm.

최미선,이주희,송지훈,임용철 대한신경집중치료학회 2017 대한신경집중치료학회지 Vol.10 No.2

"Background: The purpose of this study was to survey the anatomical angiographic finding of the aneurysm and identify parameters associated with visual recovery of the patients with Terson syndrome (TS). Methods: This retrospective study was conducted on 494 patients with aneurysmal subarachnoid hemorrhage (SAH) from 2008 to 2015. Radiologists independently reviewed findings on computed tomography scans and cerebral digital subtraction angiography. Ophthalmologists conducted ophthalmological examinations for patients who had no communication problem. The degree of visual acuity recovery (DVAR) was measured based on the visual acuity difference between the initial and sixth-month follow-up. Favorable visual recovery was defined as DVAR >0.4. Results: A total of 494 patients diagnosed with aneurysmal SAH were given admission to a single institute, of whom 171 received ophthalmological examinations. Of the total, 40 patients were diagnosed with TS and 54 eyeballs were affected by vitreous or retinal hemorrhage. In the multivariable analysis, male sex (odds ratio [OR] 9.530; 95% confidence interval [CI] 1.824-49.801), favorable Glasgow coma scale (GCS) (≥13 points) (OR 8.073; 95% CI 1.226-53.148), and anterior orientation of aneurysm (OR 5.006; 95% CI 1.842-29.751) were identified as independent factors predicting favorable visual recovery after adjusting covariables. Conclusions: TS was identified in 23.4% of patients with aneurysmal SAH. Male sex, favorable GCS at admission, and anterior orientation of the aneurysm were identified as prognostic factors for favorable visual recovery. It is proposed that positive ophthalmologic consultation and treatment can be helpful in improving vision and quality of life of TS patients. "

유방 미세석회화 조직검사에서 X선 유도 하 조직검사와 초음파 유도 하 조직검사의 유용성

최미선,송종남 한국방사선학회 2016 한국방사선학회 논문지 Vol.10 No.3

유방암에 관한 사회적인 관심이 증가되고 있는 가운데 진단의 가장 기본이 되는 검사는 유방 X선 촬영 과 유방 초음파 검사이다. 특히 유방 미세석회화는 조직학적 진단을 필요로 하며 유방 미세석회화 조직검사를 시행하고 있다. 이에 미세석회화 진단에 기본이 되는 X선 유도 하 조직검사(needle localized open biop sy)와 초음파 유도 하 조직검사(sono guided core needle biopsy)를 분석하여 평가하고자 한다. 유방 미세석회화를 주소로 내원한 환자에서 확대 촬영을 시행한 241예를 대상으로 X선 유도 하 조직검 사(needle localized open biopsy)와 초음파 유도 하 조직검사(sono guided core needle biopsy)의 연령대 별 분 포와 병소의 위치를 분석하고 확대촬영 시행 후 이루어진 검사를 분류해서 X선 유도 하 조직검사와 초음 파 유도 하 조직검사의 빈도를 분석하고 악성과 양성의 결과를 확인 하였다. 그 결과 X선 유도 하 조직검 사(needle localized open biopsy)가 64예(26.6%)로 초음파 유도 하 조직검사(sono guided core needle biopsy) 1 2예(4.9%)에 비해 5.4배 높은 것으로 나타났다. 초음파 장비의 발달과 입체정위 흡입법(stereotactic vacuum-assisted biopsy)등의 발달로 미세석회화의 조직 학적 진단방법이 다양해지고 있지만, 각각 검사의 특성과 한계점을 고려해 볼 때 X선 유도 하 조직검사(ne edle localized open biopsy)가 유방 미세석회화 병변에서는 정확한 조직학적 진단을 제공한다고 사료된다. Social interest in breast cancer has increased. The most basic exams for diagnosis include breast X-ray and breast ultrasound. In particular, breast microcalcification requires histological diagnosis, and breast microcalcification biopsy is commonly performed. Therefore, this study aimed to analyze and assess X-ray guided biopsy (needle localized open biopsy) and ultrasound guided biopsy (sono guided core needle biopsy), which are basics in diagnosis of microcalcification. Targeting 241 cases in which magnification mammography was performed for patients who visited the hospital due to breast microcalcification, age distribution and the location of lesions were analyzed in X-ray guided biopsy and ultrasound guided biopsy. By classifying exams performed after magnification mammography, the frequencies of X-ray guided biopsy and ultrasound guided biopsy were analyzed, and malignant and benign results were confirmed. The results showed that 64 cases(26.6%) were X-ray guided biopsy, which was 5.4 times higher than 12 cases(4.9%) of ultrasound guided biopsy. Due to development of ultrasound equipments, stereotactic vacuum-assisted biopsy, etc. the methods of histological diagnosis of microcalcification have become diverse, but when considering characteristics and limitations of each exam, X-ray guided biopsy is thought to be most accurate and useful.

As many companies are performing brand management as a marketing strategy to establish long-term relationships with their customers, consumers decide the actual purchasing behavior by understanding the brand attributes of the relevant company based on an evaluation standard of the products. This paper provides the basic data for improving the competitiveness of the coffee shop market continuously, and analyzes the influential relationships between each variable by limiting the brand attributes of the coffee shop and the price fairness factor that would be expected to affect the consumers' purchasing behavior as the cause variables. The results showed that the-out of brand attribute factors of the coffee shop, the brand awareness and perceived quality had significant effects on the price fairness while the influence of the shop image on the price fairness was not verified. In addition, all the brand awareness, shop image, and perceived quality had significant effects on the purchasing behavior while the statistical significance between price fairness and purchasing behavior was verified. The rationality of the price presented by the coffee shop could be judged depending on the quality perceived by the consumers. Similarly, once consumers classified the propriety of price and then perceived that a suitable price had been set up regarding the quality and service provided by the coffee shop, it was highly possible for them to include it in their actual purchasing behavior, despite the higher price than other brands'. Further research on the psychological variables affecting the purchasing behavior by securing more diverse consumers to understand their purchasing behavior for a wide range of research subjects and the generalization of research results, will provide useful data for establishing marketing measures necessary to form strong relationships between consumers and brand in the currently-saturated coffee shop market.

최미선 인문사회 21 2020 인문사회 21 Vol.11 No.3

This study investigates the changes of aggressiveness of a 15 years old female adolescent with severe disruptive behavior through art psychotherapy with 38 sessions. The BDHI and KHTP were applied to examine degrees of changes in disruptive behavior and aggression. The results were as follows: aggression was reduced from T score 80. to 58 on BDHI. And angry emotion and defiant behavior were reduced and receptive warm relation-oriented attitudes were increased on KHTP and mothers reports. The results suggest that psychotherapy rather than hard discipline or punishment might be more effective on the changes of intrapsychic structure and behavior problems. 본 연구는 파괴적 행등을 보이는 15세 청소년에게 총 38회에 걸친 미술심리치료를 시행하고, 공격성과 일상생활 행동의 변화를 조사 확인한 사례연구이다. 공격성의 변화를 관찰하기 위해서 BDHI 공격성 척도, KHTP 투사 그림검사를 적용하였다. 일상생활 행동은 부모의 보고 및 연구자의 직접 관찰 방법을 적용하였다. 연구결과, BDHI 상의 T점수척도에서 사전검사 .80, 사후검사 .58로 현격한 공격성 감소를 보였다. KHTP 상의 변화에서도 인정감, 자신감, 우호적 태도의 증진이 현저하게 들어 났다. 가정과 학교 등 일상생활 행동에서도 파괴적 공격적 행동의 현저한 감소와 교우관계에서 여러 형태의 친사회적 행동이 증가하였음을 확인할 수 있었다. 본 연구를 통해서 심한 파괴적 행동을 보이는 청소년일지라도 미술심리치료를 적용하여 조기에 치료적 개입을 한다면, 적응적이고 건강한 성장 발달을 이루도록 효과적으로 도와줄 수 있다는 임상적 결론을 얻었다.
