[논문]지반앵커의 인발저항 특성에 따른 인장 · 압축 복합 시스템 개발

임종철,염호형,권정근 釜山大學校生産技術硏究所 2008 生産技術硏究所論文集 Vol.67 No.-

앵커는 그라우트(grout)의 지지방식에 따라 인장형,압축형, 복합형으로 나누어지며,현재 인장형 앵커의 단점을 보완한 압축형 앵커가 주로 적용되고 있다. 그러나 압축형 앵커는 구속압이 적은 토사지반에 긴장 정착시 그라우트(grout)체가 인발되거나 파괴되는 약점을 가지고 있어 이런 약점을 개선시켜 토사 지반에도 사용 가능한 앵커개발이 필요하다. 본 연구에서는 인장형 및 압축형 앵커의 장점을 동시에 가지며, 특히 토사 및 풍화토에서도 앵커의 소요 인발력을 발휘할 수 있는 복합형 앵커를 개발하였다. 풍화토지반에서의 인발실험 결과 앵커체가 압축변형률과 인장변형률이 발생하는 복합적인 인발저항기구를 보였으며,압축형 앵커에 비해 소성변형이 적게 발생되어 탄성거동에 있어 복합형 앵커가 유리하게 나타났다.

Mouth breathing gives direct irritation to gingival tissue and increases gingivitis by increasing debris deposite. Generally, it is reported that gingivitis increases at puberty and it is mainly caused by microbial change and hormonal imbalance. This study included generalized gingivitis accompanying mouth breathing and localized gingival hypertrophy. This 11 years old female patient had no past medical history but she had menarchy a year ago. As a treatment, primarily eliminated the cause of mouth breathing and conducted tooth brushing instruction, scaling, and gingivectomy which resulted good.

러시아 한국학 진흥을 위한 전문 교재의 필요성과 개발의 방향 : 언어학과 문학 교재를 중심으로

김형규,장호종 中韓人文科學硏究會 2008 한중인문학연구 Vol.24 No.-

러시아 한국어교육 및 한국학은 학문 내적, 외적인 기반이 취약해 최근 증가 추세에 있는 한국학의 수요를 체계적으로 수용하지 못하고 있어 국내 한국학계와의 긴밀한 상호협조가 절실한 실정이다. 동기와 목적, 그리고 주체를 포함한 전반적인 환경이 달라졌음에도 불구하고 러시아 한국어교육은 취업을 중심으로 한 실용적인 목적에 치중되어 장기적인 차원에서 러시아 한국학의 전문성을 제고하기 어렵다. 따라서 양적으로 증가한 한국어교육 및 한국학 강좌의 많은 부분을 비전문 인력에 의존하고 있는 상황이 반복되고 있으며, 교재 개발이나 교육과정 또한 주로 일회적이고 산발적으로 차원에서 이루어지고 있다. 장기적인 차원에서 러시아 한국학의 전문성을 제고할 수 있는 실질적인 교류 협력 과정을 통해 러시아 한국학의 질적인 전환을 뒷받침하고 이를 통해 러시아 한국학의 내적 기반을 강화하는 데 기여하기 위해 한국학 전문 교재의 개발이 필요하다. 한국학 전문 교재는 회화 습득이라는 초보적, 실용적 목적을 넘어서 의사소통 능력을 고급화하고 한국문화에 대한 이해를 심화시키는 방향으로 발전시킬 수 있어야 하며, 한국문학, 역사, 사회, 경제 등을 전공하는 한국 전문가 양성의 토대를 확대하는데 기여해야 할 것이다. 또한 러시아 한국학의 질적인 전환을 위해서는 체계적이고 장기적인 계획을 바탕으로 한 실질적인 협력 관계를 구축해야 할 필요가 있다. 그리고 이러한 협력 관계는 러시아 한국학 자체의 전문성을 강화하는, 러시아 한국학의 체질을 개선하여 연구 및 교육 시스템을 안정적으로 구축하는 방향으로 이루어져야 한다. 이를 위하여 러시아 현지의 문화적 특성 및 교육환경을 반영할 수 있도록 러시아와 한국 학자 및 교육기관과의 실질적인 협력 시스템을 구축하여 한국학의 전문적 지식을 체계적으로 구성하는 것이 시급하다. Enhancing academic foundation of Koreanology overseas as well as meeting various demands of Korean language education require organic cooperation with Koreanology field in Korea. Specific situations in each region and accomplishments by each sector should be harmoniously communicated for stable and long-term development of Koreanology overseas and ultimately for promoting recognition of Koreanology throughout the world. Attention and effort from domestic Koreanology field are much needed considering demand of Koreanology and Korean language are increasing among countries with relatively weak academic foundation. Russia also has weak academic foundation on which demand of Koreanology is not systematically managed; therefore close mutual cooperation with Koreanology field in Korea is needed. Koreanology in Russia focuses more on practical purposes in which Korean language education is for job opportunities, despite the change in overall environment including objects, goals and core of Koreanology; therefore it is hard to consider specificity of Koreanology in Russia from long-term perspective. This situation led to growing dependency on non-professionals for major part of increasing Korean language education courses and Koreanology classes and majority of teaching material developments and education processes are not continuous and consistent but sporadic. In long-term perspective, development of specialized teaching materials for Koreanology is needed to enhance the internal foundation of Koreanology in Russia through practical cooperation process and change in quality of Koreanology for specificity of Koreanology in Russia. Specialized teaching materials for Koreanology should help with more sophisticated communication skills beyond beginner level communication skill and practical purposes; promote further understanding on Korean culture; and contribute to expanding foundation to train experts of Korea in Korean literature, history, society and economy. In addition, practical cooperation based on systematic long-term plan is needed to change the quality of Koreanology in Russia. Such cooperative relationship should be able to enhance specificity of Koreanology in Russia, improve the quality of Koreanology and establish stable research and education system within Russia. Practical cooperative system among scholars and educational organizations in Russia and Korea should be established to systematically organize specialized knowledge of Koreanology.

This study is to investigate the psychological characteristics of children suffering from hematologic cancer patients and to compare them with those of their siblings as control according to age groups. We also examined the psychopathology of their patents and family environment, Forthis reason, 1) We examined the difference in age groups(children vs adolescents) using the self-report psychological questionnaire for anxiety and depression. 2) We examined the difference of the study group by age variable using the child behavior checklist for parents. 3) We examined the difference of the result reported by adolescents and by the parents. 4) We also examined the psychopathology of the parents using self-reports for parents. So 22 leukemic outpatients(10 children and 12 adolescents) in their maintenance chemotherapy phase for acute lymphocytic leukemia or lymphoma have completed the psychiatric interviews and the self-reports. For the self-reports, we have used Children's Depression Inventory(CDI), revised Children's Manifest Anxiety Scale(RCMAS), State-trait Anxiety Inventory for Children(STAIC) for all age groups and in additon the Youth Self Report(YSR) for adolescents. To evaluate the children's problem behavior, Child behavior checklists(CBCL) were filled up by their parents. And 36 parents performed Symptomcheck List-90-Revison(SCL-90-R), Beck Depression Inventory(BDI). We concluded that the child hematologic cancer patients have the tendency to express no prominent depression or anxiety and no age effect when self-reports such as CDI, RCMAS, STAIC were administered. And the siblings showed no significant difference compared to cancer patients. However, when CBCL was administered to by the parents, there were high scores in the childhood leukemic patients and the adolescent sibling controls group comparing to the other groups and such trend was more prominent in the leukemic patients group(p<0.05). also when the YSR and CBCL were compared, the YSR showed high scores in the both adolescent leukemic patients(p<0.01) and sibling controls group(p<0.05). Therefore we can suggest that the leukemic patients have the tendency to repress their own symptoms as they grow older. the patents are relatively well adapted when there are leukemic patients in their family.

김형권,이은학,우호환,김종석,이덕출 (사단법인)韓國火災 ·消防學會 1996 한국화재소방학회논문지 Vol.10 No.3

The Polyimide thin films based on PMDA and 4,4'-DDE were fabricated by VDPM, and their heat resistance characteristics were invastigated by TGA(Thermogaravimetry Analyzer). It was found that deposition rate decreased with increasing substrate temperature and the thin films were not fabricated over the substrate temperature of 70℃. T_TG of 5% weight loss temperature is 565℃, 397℃ and 210℃ at the substrate temperature of 20℃, 40℃ and 70℃, respectively. It is realized that the endurace temperature for 20,000 hour of thin films fabricated at 20℃ and 40℃ is 230℃ and 200℃, respectively.

Computer Graphics에 의한 3성분계 Wilson, NRTL 및 UNIQUAC 방식을 이용한 VLE 추정방식의 비교

신형섭,박종철 慶熙大學校 1988 論文集 Vol.17 No.-

The purpose of this study is to estimate VLE by means of the Wilson, NRTL, UNIQUAC equations and to compare with these three methods for two ternary systems: ethanol-benzene-cyclohexane, cyclohexanone-cyclohexanol-phenol, by the computer graphic technology. The temperatures and compositions of two systems were estimated by means of three TPTT equations. Isothermal lines of these two ternary systems were graphically illustrated from these estimated values and the reported experimental values. As a result of the analysis of the parameters and computer graphics, these parameter pairs changing with respect to the temperature and composition of the solutions. From the result of plotting the parameter pairs, A_12, vs, A_21, a locus contour between two parameters is observed, therefore numerous number of roots to satisfy these TPTT equations are found. These phenomena is nearly identical with the previously reported results that there are some correlation between these parameter pairs.

이계형,김종철 전남대학교 치과대학 1995 전남치대논문집 Vol.7 No.1

The purpose of this study was to compare and evaluate the upper airway structure between the snorers and asymptomatic control subjects depending on the positional change. Lateral cephalograms in the upright and supine position were taken in 25 female snorers and 20 female asymptomatic control subjects. The length and the area of the soft palate, tongue and airway were measured and evaluated statistically. The results obtained were as follows : 1. The snorers showed longer and higher tongue, narrower and longer airway, inferiorly positioned hyoid bone, longer and broader soft palate and narrower hypopharynx than the control subjects both in the upright and supine position. In addition, the snorers showed broader tongue area and narrower oropharynx area than the control subjects in supine position. 2. Depending on the positional change from upright to supine position, the controls and the snorers showed decreased airway length and superior positioned the hyoid bone. In addition, the snorers showed decreased tongue length and height, airway length and thickness and oropharynx area, but increased tongue area and soft palate area.
