        In this study, 24 curved resin blocks were prepared by one of the following four methods: 1) Conventional technique using K-flexo files 2) Step-back technique using K-flexo files 3) Crown-down technique using K-flexo files 4) Canal Master instrumentation using Canal Master Resin blocks were sectioned, photographed, and evaluated the mean centering ratio and the mean area of dentin removed before and after the instrumentation. The results were as follows: 1) the mean centering ratio 1. In the level 1 and level 3, there was no significant difference in the mean centering ratio. 2. In the level 2, Step-back technique showed the worst mean centering ratio among the tested groups ( p<0.001 ) and there was no significant difference between the other three groups. 3. In the level 4, Canal Master instrumentation and Step-back technique showed better mean centering ratio than the other two techniques ( p<0.001 ) and there was no significant difference between the two techniques. 2) the mean area of dentin removed 1. In the level 1 and level 3, there was no significant difference in the mean area of dentin removed. 3. In the level 2, Canal Master instrumentation removed less dentin than the other three techniques ( P<0.01 ). 4. In the level 4, Crown-down technique removed less dentin than the other three techniques ( P<0.05).

      • 질병과 수술이 성인환자의 신체상에 미치는 영향에 관한 연구

        박미희,이정희 중앙대학교 의과대학 의과학연구소 1983 中央醫大誌 Vol.8 No.3

        A study was undertaken to determine the influence of the disease or operation on the body image of adult. Body image, as a means of body to itself, would be changed continuously by growth, disease, accident or environmental factors. In adults Body Image is threatened by disease and operation, and changed the established characteristics, or leads to loss of self-esteen. Therefore, this study was to compare the importance of body parts with change of body image due to disease or operation between normal adults and patients. In this study, samples are 119 patients admissioned into medical, surgical wards of C University Hospital, H University Hospital and 126 Normal adults. The tool used in this study is made by itself for measurement of body image, it is base upon the body Cathexis Scale by Secord and Jourard, Semantic Differential Scale by Osgood and Free word thinking method. Data gathering was performed from April 1, 1983 to April 30, 1983. and when data analysis mean, standard deviation, t-test and spearman's rank correlation were used. Results of the study are as follows: 1. Hypothesis(1) is selected that "The patients' group has more negative body image than Normal Asults' Grou.(BC Scale: t=2.84 P<0.01, SD Scale: t=6.71 P<0.001) 2. Hypothesis(2) is selected that "Medical patients' group has more negative body image than normal adults' group"(BC Scale: t= 1. 81 p<0. 1, SD Scale: 5. 61 p<0. 001) 3. Hypothesis(3) is selected that "Surgical patients' group has more negative body image than normal adults' group." (BC Scale: t=2.65 p<0. O5, SD Scale: t=5.37 p<0. 001) 4. Hypothesis (4) is not selected that "Surgical patients' group has more negative body image than medical patients group."(BC Scale: t= -0.47 P>0.05, SD Scale: t= -1.07 P>0.05) 5. Hypothesis(5) is not selected that "In patients, the group with pain has more negative body image than the group without pain."(BC Scale: t= -1.38 P>0.05, SD Scale: t=-1.07 P>0.05) 6. Hypothesis(6) is selected that "In normal, adults, the group with pain has the negative body image than the group without pain. "(BC Scale: t= -1.25 p<0.05. SD Scale: t= -2.55 p<0.05) 7. Hypothesis (7) is selected that "In total group, the group with fain has the negative body image than the group without pain,"(BC Scale: t= -1. 93 p<0. 1, SD Scale: t= -2. 19 p<0.05) 8. Hypothesis (8) is not selected that "In patients, the group with admission experience has the negative body image than the group without admission experience,"(BC Scale: t =-0.30 p>0.05, SD Scale: t= 1.03 p>0.05) 9. Hypothesis(9) is not selected that "In normal adults, the group with admission experience has the negative body image than the group without admission experience. " (BC Scale: t= -1. 19 P>0. 05, SD Scale: t= -0. 96 p>0.05) 10. Hypothesis (10) is not selected that "in total group the group with admission experience has the negative body image than the group without admission experience."(BC Scale: t= -0.97 P>0.05,SD Scale: t=0.52 p>0.05) 11. Hypothesis(11) is selected that "In patients, female has the negative body image that male."(BC Scale: t=2.06 p<0.05) 12. Hypothesis(12) is selected that "In normal adult, female has the negative body image than male."(BC Scale: t=2.57p<0.05) 13. Hypothesis(13) is selected that "In total group, female has more negative body image than male". (BC Scale: t =2.60 P<0. 0l) 14. Hypothesis(14) is selected that "Body part, which tested by free word thinking method, is not influenced by disease and operation" (r= 0.9528 r=0.9515 p<0. 001) It is concluded that disease and operation lead to change the negative body image in adults, but the priority of importance of all parts of body is not effected by (disease and operation.

        처리특성에 따른 주관적 감각인식의 차이

        박미희,김경미,Park, Mi-Hee,Kim, Kyeong-Mi 대한감각통합치료학회 2007 대한감각통합치료학회지 Vol.5 No.1

        Objective: This study was to provide a standard for the evaluation of The Korean version of Adolescent/Adult Sensory Profile(K-ASP) for University students and to investigate the difference of the subjective sense recognition regarding the characteristics of sensory processing. Method: The subjects consisted of 84 University students. A researcher examined subjective sense recognition and K-ASP for subjects. Visual Analog Scale used to evaluate subjective sense recognition and K-ASP was utilized to evaluate the characteristics of sensory processing. Results: 1. The average scores and standard deviation of K-ASP were $32.93{\pm}7.88$ for low registration group, $39.39{\pm}6.55$ for sensory seeking group, $38.94{\pm}9.13$ for sensory sensitivity group, and $34.24{\pm}7.85$ for sensory avoiding group. 2. The correlation between the total score on an each quadrant and the subjective sense recognition are -.27 for low registration group, .11 for sensory seeking group, .09 for sensory sensitivity group and .12 for sensory avoiding group. It showed the statistically significant correlation between the total score of low registration and the subjective sense recognition group(p<.05). 3. The average scores and standard deviation of the subjective sense recognition were $5.22{\pm}1.56$ for high threshold and $7.28{\pm}1.70$ for low threshold. The subjective sense recognition according to the characteristics of sensory processing showed the statistically significant difference. Conclusions: This study supports the theory that there is the difference of sensory recognition according to each individual and we found that people with difficulties of sensory processing acknowledge their characteristics of sensory processing well. Evaluation of sensory processing ability through interview or questionnaire supports the fact which it is reliable.

        Blood Cyst of Subvalvular Apparatus of the Mitral Valve in an Adult

        박미희,정수연,윤호중,진정연,이종환,정해억 한국심초음파학회 2012 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.20 No.3

        Blood cysts of the heart are rare benign tumors, usually involving the cardiac valves. They are found mainly in the first month of life and in children; and are rarely seen in adults. Here, we report a case of a blood cyst on the subvalvular apparatus of the mitral valve, which was incidentally discovered during chest computed tomography in a 47-year-old man. To the best of our knowledge, this is the first reported case of blood cyst of the heart in an adult in Korea.

        The pleckstrin homology domain of phospholipase D1 accelerates EGFR endocytosis by increasing the expression of the Rab5 effector, rabaptin-5

        박미희,최강열,민도식 생화학분자생물학회 2015 Experimental and molecular medicine Vol.47 No.-

        Endocytosis is differentially regulated by hypoxia-inducible factor-1α (HIF-1α) and phospholipase D (PLD). However, the relationship between HIF-1α and PLD in endocytosis is unknown. HIF-1α is degraded through the prolyl hydroxylase (PHD)/von Hippel–Lindau (VHL) ubiquitination pathway in an oxygen-dependent manner. Here, we show that PLD1 recovers the decrease in epidermal growth factor receptor (EGFR) endocytosis induced by HIF-1α independent of lipase activity via the Rab5-mediated endosome fusion pathway. EGF-induced interaction of PLD1 with HIF-1α, PHD and VHL may contribute to EGFR endocytosis. The pleckstrin homology domain (PH) of PLD1 itself promotes degradation of HIF-1α, then accelerates EGFR endocytosis via upregulation of rabaptin-5 and suppresses tumor progression. These findings reveal a novel role of the PLD1-PH domain as a positive regulator of endocytosis and provide a link between PLD1 and HIF-1α in the EGFR endocytosis pathway.

        사회통합전형 입학생의 학업성취도 변화에 관한 탐색적 연구

        박미희,홍백의 한국교육사회학회 2010 교육사회학연구 Vol.20 No.3

        One of the major features of Korean educational policies over the last twenty years, has been to develop specialized admission programs for recruiting students with various social and demographic backgrounds. In this context, many universities have developed admission programs for socially disadvantaged groups, such as students in rural areas, in poverty and from occupational high schools. To ensure that students successfully adapt to their academic life, it is necessary to find out how the academic performance of the students change over the period of attendance and what the obstacles are to their learning. This study compared the changes in academic performance of these groups with that of their counterpart and suggested several policy measures to implement in order to overcome the obstacles and improve their academic performances. The results show that while the GPAs of students in rural areas and from occupation high schools are very low at the initial stage, they sharply increase and become higher than that of any other group at graduation. In addition, the FGI suggested that the more disadvantaged students ask their university to provide various financial supports, basic foreign language programs and staffs for various mentor programs. 본 연구는 지난 20년간 대입정책의 다양화ㆍ특성화 경향으로 인해 도입ㆍ확대되고 있는 사회통합전형 입학생의 학업성취도 및 학업성취 저해요인에 대해 알려진 바가 거의 없다는 문제의식 하에, 이들의 학업성취도가 어떤 변화양상을 보이는지 밝혀내고 이들의 학업수행을 저해하는 요인을 파악해 대학차원의 지원방안을 제안하기 위해 수행되었다. 이를 위해 먼저 이들의 학업성취도 변화경향을 사회통합전형 세부유형별로 구분하여 구체적으로 살펴보고, 표적집단 면접(FGI)을 통해 이들이 학업수행과정에서 겪고 있는 어려움과 학업성취저해요인을 파악하였다. 사회통합전형 입학생의 학업성취도 변화경향을 분석한 결과, 전체적인 평점평균은 일반전형 입학생이 가장 높은 것으로 나타났고, 사회기여자와 특수교육대상자전형 입학생의 평점평균이 다소 떨어지는 것으로 나타났다. 그러나 농어촌전형과 전문계고교전형 입학생의 경우 첫 학기의 성적은 매우 낮았으나 성적이 지속적으로 상승하는 경향을 보였으며, 4학년 졸업시에는 일반전형 학생의 평점평균보다 오히려 높은 것으로 나타났다. 사회통합전형 입학생의 FGI 분석결과, 참여자들은 영어와 전공기초지식에서 본인의 능력이 떨어진다고 인식하고 있는 것으로 나타났다. 이들의 학업능력이 저조한 이유는 열등감, 사교육 혜택부재, 경제적 여건마련으로 인한 공부시간의 부족 등으로 조사되었다. 이것은 참여자의 사회경제적 배경이 결국 대학에서의 학업성취도에까지 영향을 미치고 있는 것을 의미하며, 성공적 대학생활을 위해서는 기회의 평등 이상의 지원이 필요함을 시사한다. 본 연구에서는 사회통합전형 입학생의 성공적 대학생활을 위한 대학차원의 지원방안으로 재정 지원, 입학전후의 학업지원, 학교생활 적응을 위한 멘토링 지원, 사회통합전형 입학생 지원을 위한 전담인력 배치 및 부처 간 협조체계 구축, 기숙사 우선배정 등의 각종 복지 혜택 등을 제안하였다.

        COHEN의 합치도의 두 가지 역설을 해결하기 위한 새로운 합치도의 제안

        박미희,박용규,Park, Mi-Hee,Park, Yong-Gyu 한국통계학회 2007 응용통계연구 Vol.20 No.1

        두 평정자가 있는 이차원 분류표에서 우연에 의한 합치 비율을 보정한 Cohen의 합치도($\kappa$)는 문제점이 있는 측도로 알려져 있다. $\kappa$는 평정자의 분류 비율(주변확률)에 매우 민감하고, 합치도로서의 조건도 만족하지 못한다. 그러나 $\kappa$를 비롯한 기존 합치도들은 주변확률이 0.5에 가까울 때 안정되며 비슷한 값을 갖는다. 본 연구에서는 이차원 분류표의 불균형적 주변분포를 보정함으로써 $\kappa$의 역설을 해결하는 새로운 합치도 H를 제안한다. 또한 예제를 통해 기존의 합치도들과 제안된 합치도를 비교한다. In a $2\times2$ table showing binary agreement between two raters, it is known that Cohen's $\kappa$, a chance-corrected measure of agreement, has two paradoxes. $\kappa$ is substantially sensitive to raters' classification probabilities(marginal probabilities) and does not satisfy conditions as a chance-corrected measure of agreement. However, $\kappa$ and other established measures have a reasonable and similar value when each marginal distribution is close to 0.5. The objectives of this paper are to present a new measure of agreement, H, which resolves paradoxes of $\kappa$ by adjusting unbalanced marginal distributions and to compare the proposed measure with established measures through some examples.
