The purpose of this study was to examine the difference of lateral cephalometric charateristics between dental protrusion and crowding individuals and to find out the possible etiologic factors of each malocclusion. Twenty nine dental protrusion and twenty two crowding individuals were selected from the 4,500 patient records. The tooth size was measured from central incisor to first molar using diagonstic study cast and was compared between two groups. After tracing the lateral cephalometric radiographs, measurements for skeletal factor, hyoid bone position, and incisal position were identified. The means and standard deviations of the measurement of each group were calculated and compared between two groups. Through the comparison of the measurement between two groups, following results were obtained 1. As a result of comparing the tooth size of dental protrusion group with that of crowding group, there was no significant difference between two groups. 2. In the comparison of skeletal measurements, S-N, A'-Ptm', SNA, ANB, and facial convexity of protrusion group showed greater value than crowding group. 3. The measurements of hy-PP and hy-MP showing vertical position of hyoid bone were smaller in protrusion group than those in crowding group. 4. The measurement of hy'-Go showing anteroposterior position of hyoid bone was larger in protrusion group than that in crowding group. The results of the present study showed that dental protrusion inidviduals had the tendency of maxillary protrusion and antero-superior position of the hyoid bone compared to crowding individuals, and these features could be explained as possible etiologic factors of dental protrusion or crowding malocclusion.

This research has an purpose of enhancing the design capabilities of the body painting motivated with the drawings by applying the represented patterns and colors of the works into body painting designs and creating them. Since the body painting is so similar with the drawings but a cubic canvas so-called as the body is given, delicate planning is prerequisite for the design process. More than anything else, picking the very drawings that are matched up with various patterns and beautiful colors should be made in order to proceed with creative design conceptualization. Among a wide range of the drawings that meets the requirements, a series entitled as Sun Rise-Faith, Hope, and Love was chosen. One of the research methods was to make an advisory consultation with a painter, Dong-kwon Shin by interview, collect 745 paintings of series of the Sun Rise - Faith, Hope, and Love, categorized and analyzed their patterns into 8 types. In addition, after selecting desirable colors that can be utilized for body-painting, we produced the image scale as well as tone map by utilizing solid coated of custom functions equipped by the color picker throughout Adobe Photoshop CS program and changing the transcription method into the pantone method. After that, based on the desirable patterns and colors for body-painting, image map is produced. Throughout this, a design proposal is documented and the body painting work is fully completed. In this way, the examples of analyzing methods represented by the patterns and colors were indicated, and they will be much helpful to get used to the threedimensional sense through applying the features of surface-level work into a cubic body.

연구배경: 당뇨병환자들에서 우울증의 유병률이 높고 이는 환자들이 생활 개선 요법을 적절히 수행하는데 지장을 주어 혈당 조절을 악화시키거나 합병증의 발생을 증가시킬 수 있다. 본 연구에서는 두 가지 설문 조사를 통해 우리나라 당뇨병환자들의 우울증의 빈도 및 자가 관리 정도에 관해 조사하고자 하였다. 방법: 2008년 7월에서 2008년 12월 사이에 제2형 당뇨병 치료를 위해 성모병원 외래를 방문한 환자들을 대상으로 Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS)와 Summary of Diabetes Self-Care Activities (SDSCA)를 이용하여 이들의 우울증 여부와 식사 조절, 운동, 혈당 체크, 발 관리, 금연 등의 자가 관리 수행 정도를 조사하였다. 또한 당뇨병의 유병 기간, 만성 합병증, HbA1c, 총 콜레스테롤, 중성지방, 고밀도 지단백 콜레스테롤, 저밀도 지단백 콜레스테롤을 측정하였다. 위의 결과들을 토대로 당뇨병환자들의 우울증 빈도 및 우울증과 자가 관리, 우울증과 혈당 조절 정도와의 관계를 Two-tailed t tests, chi-square analysis, Pearson`s correlation coefficient 방법으로 조사하였다. 통계적 유의수준은 0.05 미만으로 정의하였다. 결과: 총 191명의 환자들이 설문 조사를 완료 하였고 이중 39명(20.4%)의 환자가 주요 우울 장애에 이환되어 있는 것으로 나타났다. 그러나 우울증이 있는 환자 39명 중 6명(15.3%)만이 이에 대해 전문가의 진단 또는 치료를 받은 기왕력이 있었다. 우울증이 없는 군과 있는 군 사이의 자가 관리 정도를 비교해 보았을 때 적절한 식사 요법과(평균점수: 18.54 vs 15.94, P=0.046) 자가 혈당 측정은(평균점수: 4.05 vs 2.69, P=0.047) 우울증이 있는 환자군에서 통계적으로 유의하게 그 수행 정도가 떨어졌다. 그러나 규칙적 운동, 매일의 발 관리, 금연 여부 등은 두 환자군 사이에 의미있는 차이를 나타내지 않았다. 당화혈색소, 총 콜레스테롤이나 중성지방, 고밀도 지단백 콜레스테롤, 저밀도 지단백 콜레스테롤 수치도 우울증이 있는 군과 없는 군 사이에 통계적으로 유의한 차이를 나타내지는 않았다. 결론: 당뇨병이 있는 환자들은 건강한 성인에 비해서 우울증이 동반되는 경우가 더 흔하며 이들 중 상당수가 적절히 진단되지 않고 있다. 우울증이 있는 당뇨병환자들은 식사 조절이나 혈당 체크와 같은 자가 관리의 수행 정도가 우울증이 없는 당뇨병환자에 비해 낮으며 따라서 당뇨병환자들의 우울증 동반 여부에 대해 적절히 진단하고 치료하는 것이 필요하다. Background: Depression is known to be a risk factor for type 2 diabetes mellitus. Conversely, diabetes is also a risk factor for depression, and patients with diabetes have nearly twice the risk of comorbid depression as the general population. Depression in patients with diabetes may cause poor clinical outcomes through lower adherence to self-care activities such as exercise, diet control, and glucose monitoring. Furthermore, diabetic patients with depression are more likely to suffer from microvascular or macrovascular complications. We explored the prevalence of major depressive disorder in Korean diabetic patients and its impact on self-care activities and glucose control. Methods: We surveyed depressive symptoms and self-care activities in 191 type 2 diabetic patients from the outpatient clinic of the St. Mary`s hospital. Two questionnaires were used for assessment, the Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS) and the Summary of Diabetes Self-Care Activities (SDSCA). Results: Of the 191 respondents who completed questionnaires, 39 (20.4%) patients were categorized as having major depressive disorder. Among the depressed patients, only six (15.3%) had been previously evaluated and managed for their psychiatric problems. The incidence of depression was significantly higher in female diabetic patients compared to patients without depression (74.4% vs. 45.4%, P<0.001). Patients with depression showed significantly poorer diet control (18.5 vs. 15.9, P=0.046) and less glucose monitoring (4.1 vs. 2.7, P=0.047). However, there were no differences in exercise, foot care, or smoking status between the two groups. Additionally, metabolic parameters such as HbA1C and lipid profile were not significantly different between the two groups. Conclusion: Many diabetic patients are suffering from depression and exhibit poorer self-care activities than patients without depression. Identifying and managing depressed diabetic patients may help improve their self-care activities. (Korean Diabetes J 33:432-438, 2009)

Microstructural changes in grain interior and grain boundary by formation of metastable and stable phases related to age-hardening in an Au-Cu-Ag-Pd alloy

Cho, Su-Yoen,Lee, Gwang-Young,Jeong, Ji-In,Kwon, Yong Hoon,Kim, Hyung-Il,Seol, Hyo-Joung Cambridge University Press (Materials Research Soc 2013 Journal of materials research Vol.28 No.9

<▼1><B>Abstract</B><P/></▼1><▼2><P>The hardness changes caused by formation of the metastable and stable phases were examined and correlated with the microstructural changes in grain interior and grain boundary during aging at 350 °C to clarify the age-hardening and softening mechanism of a low-gold Au-Cu-Ag-Pd dental alloy. Aging in this context refers to the time-delay that occurs wherein such alloys are kept at elevated temperatures for periods upto many hours to allow precipitation or ordering to take place. During the period of increasing hardness, the matrix was separated into the Ag-rich α1 and AuCu I phases through the metastable phases, forming block-like structure. The apparent hardening was attributed primarily to lattice strain due to the tetragonality of AuCu I′ [the primer (′) here indicates a metastable phase; likewise (I) and (I′) indicate stable AuCu I and metastable AuCu I′ phases, respectively] and AuCu I phases along the <I>c</I>-axis, secondarily to the coherency or semicoherency strain between the metastable α1′ and AuCu I′ phases and between the α0 and AuCu I phases along the <I>a</I>-axis. The apparent softening was caused primarily by growth and coarsening of the lamellar structure in the grain boundaries, secondarily by coarsening of the block-like structure in the grain interior.</P></▼2>

예비유아교사의 정서지능 및 자아탄력성이 교수효능감에 미치는 영향

김수연(Kim, Su-Yoen) 한국어린이미디어학회 2020 어린이미디어연구 Vol.19 No.4

본 연구는 예비유아교사의 정서지능과 자아탄력성이 교수효능감에 미치는 영향을 분석하는데 목적이 있다. 이를 위해 유아교육과 3학년 재학생 202명을 대상으로 교수효능감, 정서지능, 자아탄력성에 대한 설문조사를 실시하였다. 본 자료는 SPSS WIN 24.0을 이용하여 Pearson 적률상관과 단계적 중다회귀분석을 통해 검증하였다. 그 결과, 예비유아교사의 교수효능감과 정서지능, 자아탄력성은 정적상관이 있는 것으로 나타났다. 또한 정서지능은 교수효능감을 가장 크게 영향을 미치는 예측변인으로 나타났으며, 자아탄력성은 추가적 예측변인으로 나타났다. 하위영역별로는 교수효능감을 예측하는 가장 강력한 변인으로 자아탄력성의 감정통제가 나타났고, 그 다음으로 정서지능의 자기정서인식, 정서조절, 자아탄력성의 긍정적 미래지향성 순으로 영향을 미치는 추가적 예측변인으로 밝혀졌다. 이러한 결과는 예비유아교사의 교수효능감을 효과적으로 증진시키기 위해서 개인차원의 정서관리를 기반으로 하여 자아탄력성을 증진시킬 수 있어야 함을 시사한다. The purpose of this study was to analyze the effects of pre-service early childhood teacher s emotional intelligence and the ego-resilience on teaching efficacy. For this purpose, we conducted a self-reporting questionnaire survey with 202 third year undergraduate students who were in early childhood education in Seoul and Gyeonggido to investigate their emotional intelligence, ego-resilience and teaching efficacy. The research data were analysis using Pearson correlation and step-wise multi regression in SPSS 24.0 program. Results showed a positive correlation among teaching efficacy, emotional intelligence and ego-resilience. Additionally, the results indicated that emotional intelligence was the predictor variable that has the most significant relative effect on the teaching efficacy, and ego-resilience was an additionally predictor variable of the teaching efficacy. Moreover, the results of this study indicated that the ‘emotional control’ significantly predicts teaching efficacy in the subarea. Additionally, the following predictor variables were found: ‘emotional recognition’, ‘emotional regulation’, and ‘positive future orientation’. The results suggest that in order to enhance the teaching efficacy of pre-service early childhood teachers, it is necessary to improve ego-resilience and emotional intelligence.
