스카른 Zn-Pb-Cu 복합광석을 구성하는 주요 구성 광물의 정량분석을 목적으로, 마이크로 포커스 X-ray 단층촬영 장비를 이용한 스카른 복합광석의 3차원 비파괴검사를 수행하였다. X-ray 단층화상의 화상결함을 감소시키고자 제안된 화상보정법을 이용하여 화상들을 보정한 후에 3차원으로 재구성하였다. 주사전자현미경(SEM)에 의한 표면분석과 보정된 X-ray 단층화상을 비교하여 주요광물에 대한 CT 값의 범위를 결정하였다. 재구성화상 내 전체 광물의 체적비율을 분석한 결과, 황화광물 20.5%, 맥석광물 79.5%로 평가되었다. X-ray 3차원 단층화상 정량분석법은 광석 내 유용광물의 부존 형상과 회수율 분석에 유용하게 적용될 것으로 기대된다. A micro-focus X-ray computed tomography (CT) was employed to determine quantitative phase analysis of skarn Zn-Pb-Cu ore by nondestructive visualization of the internal mineral distribution of a skarn ore. The micro CT images of the ore were calibrated to remove beam hardening artifacts, and compared with its scanning electron microscope (SEM) images to set the threshold of CT number range covering sulfide ore minerals. The volume ratio of sulfide and gangue minerals was calculated 20.5% and 79.5%, respectively. The quantitative 3D X-ray CT could be applied to analyse the distribution of economic minerals and their recovery.

To examine the effects of story retelling on middle school students’ speaking ability and learning attitudes, this study used ESPT Teens, the questionnaires, and the self-assessments of 120 first-year boys in a middle school. The results are as follows. Firstly, a statistically significant difference did emerge between the control and the experiment group on students’ speaking ability as well as between pre-test and post-test of the experimental group. There was also difference in fluency, comprehension, and accuracy as the rubric of speaking ability between pre-test and post-test of self-assessment. Secondly, while in the low level group of ESPT Teens there was difference in all parts of the rubric of speaking ability between the control and the experimental group, in the high group there was also difference except pronunciation. In the low and the high group of experimental group, there was significant difference in all parts of the rubric of speaking ability. While in the low level group of the self-assessment there was difference except pronunciation, in the high level group there was no difference in pronunciation and accuracy. Lastly, the story retelling had a positive effect on the students’ self-directed ability and confidence between the experimental and the control group, but it did on the experimental group students’ self-directed ability, interest, and confidence. This study suggested that English teachers should use as many story retelling activities as they could with various English storybooks, and that they should correct the errors of the pronunciation during the discussion at the end of each class.

The marine benthic algal flora and biomass of Chuja Island, southern coast of Korea, was investigated. The collections of intertidal marine algae were made at two sites, Yecho of Hachujado and Hupo of Sangchujado, from October 2006 to July 2007. A total of 162 species, including 15 green, 47 brown and 100 red algae, were identified in this study. The occurrence of species according to season was abundant during spring to summer and less in autumn. The vertical distribution of intertidal zone in Chujado was characterized by Gloiopeltis spp., Myelophycus simplex, Ishige okamurae, Chondrus ocellatus, Grateloupia elliptica, Hizikia fusiformis and Sargassum spp. The average biomass of macroalgae was measured as 400 g wet wt m$^{-2}$. The dominant species based on the biomass were Sargassum yezoense, S. coreanum and Hizikia fusiformis. ESG II (ecological state group) as an opportunistic species, including sheet form, filamentous form, and coarsely branched form, occurred 85.8% in the intertidal seaweeds. These results provide a baseline for future monitoring studies in the Chuja Island.

다문화가족의 가정폭력에 관한 연구

박애란(Park Ae Ran),정미희(Jeong Mi Hee),김정애(Kim Jeong Ae),체첵델게르(Tsetsegdelger) 한국인권사회복지학회 2018 인권복지연구 Vol.20 No.1

한국은 2000년대 초부터 결혼이민자가 증가하면서 다문화가족이라고 하는 새로운 가족형태가 형성되었고 다문화가족은 점차 증가하고 있는 추세이다. 이러한 다문화가족의 증가와 함께 다양한 사회문제가 발생되고 있는데 그 중결혼이주여성과 관련하여 제기되고 있는 가정폭력의 문제는 인권이나 복지차원에서 중요하게 다뤄져야 할 필요가 있다. 정부에서는 다문화가족의 가정폭력 문제와 관련하여 다양한 정책들을 제시하고는 있지만 주로 결혼이주여성을 한국 사회에 잘 적응시키고 많은 외국인들을 한국 사회에 유입시키는데 중점을 두고 있어서 그 실효성이 부족한 상황이다. 이에 본 연구에서는 건강한 다문화가족의 정착을 위하여 다문화가족의 가정폭력 현황과 실태를 살펴보았으며 그 대안으로 국제결혼 대상자에 대한 상담 및 교육 실시, 국제결혼 중개업체의 관리감독 강화, 결혼이민자들의 자조모임 활성화, 부부교육 및 부모교육 지원, 다문화가족지원센터의 상담 강화, 지방자치단체의 다문화가족의 가정폭력피해자에 대한 지원의 의무화, 다문화가족의 가정폭력피해자에 대한 주거지원 사업, 가정폭력 근절을 위한 사회분위기 조성 등을 제시하였다. In Korea, since the beginning of the 2000s, the number of marriage immigrants has increased, and a new family type called a multicultural family has been formed and the number of multicultural families is gradually increasing.  As the number of multicultural families increases, various social problems are occurring. Domestic violence, which is raised in relation to married immigrant women, needs to be dealt with in terms of human rights and welfare. Although the government presents various policies related to the domestic violence problem of multicultural families, the government mainly focuses on adapting married immigrant women to Korean society and introducing many foreigners into Korean society. The purpose of this study is to investigate the status and actual condition of domestic violence of multicultural families in order to establish a healthy multicultural family and to provide consultation and education on international marriage victims, strengthen management supervision of international marriage brokers, Support for parents education, support for multicultural family support centers, mandatory support for victims of domestic violence by localgovernments in multicultural families, housing support projects for victims of domestic violence by multicultural families, And the creation of a social atmosphere.

Objectives : The purpose of the study is to investigate the self awareness of oral health, dental calculus and gingivitis according to smoking in soldiers. Methods : A self-reported questionnaire was filled out by 601 soldiers in Jeonnam military unit from April 7 to 23, 2013. The screening for oral examination was performed in the soldiers. The data were analyzed for frequency analysis and chi-square test by using SPSS 21.0 program. Results : The self awareness of smoking on oral health accounted for 27.0% in good status in nonsmokers, 23.5% of the past smokers answered good, and 16.5% of the smokers answered good. Approximately, 68.7% had dental calculus(p<0.05). The smokers tended to have more gingivitis than the nonsmokers and the past smokers(p<0.05). Conclusions : Smokers had low level of self awareness of oral health than the nonsmokers and the past smokers.

Metaplastic carcinomas of the breast comprise a heterogeneous group of neoplasms that are regarded as a ductal carcinoma that undergos metaplasia into a nonglandular growth pattern. Metaplastic carcinoma is uncommon, accounting for fewer than 5% of breast carcinomas. It has a poorer prognosis than most other breast malignancies. We report the mammographic and sonographic findings in a 52-year-old woman of pathologically proven metaplastic carcinoma.

성인에서 발생한 원발성 종격동 T세포 림프아구성 림프종 : 증례보고

이운하,정미희,정경순 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.4

림프아구성 림프종은 고등급 악성종양으로서 적절한 치료를 하지 않을시 빠르게 치명적인 경과로 진행한다. 원발성 종격동 림프종은 대부분 호지킨 림프종, 큰 B 세포 림프종(large B cell lymphoma), 림프모구 림프종(lymphoblastic lymphoma)이다. 원발성 T 세포 림프아구성 림프종은 성인에서 드문 형태의 종격동 림프종이며 영상학적 보고는 드물다. 이에 저자들은 성인에서 원발성으로 종격동에 발생한 T세포 기원의 림프아구성 림프종 1예를 경험하였기에 보고하고자 한다. Lymphoblastic lymphoma is high-grade malignancy and rapidly fatal course without appropriate treatment. It is well known as a highly malignant tumor in children, but is rare in adults. Radiologic report of lymphoblastic lymphoma is rare. We report here on a case of a primary mediastinal precursor T-cell lymphoblastic lymphoma in a 46-year-old woman.
