박혜숙(Hye Sook Park) 한국교육심리학회 2013 敎育心理硏究 Vol.27 No.2

본 연구에서는 Rasch 측정모형을 사용하여 다문화 수용성 척도를 타당화하였다. 이전의 연구(박혜숙, 원미순, 2010)를 바탕으로 다문화 수용성을 인지, 정의, 행동 측면에서 문항표본을 확대하고 전국의 4년제 대학생을 대상으로 설문을 실시하였다. 다문화 수용성 척도에 대하여 인지(n=14), 정의(n=12), 행동 측면(n=13)을 나타내는 39개의 문항을 개발하고, 개발한 도구에 대하여 Messick(1989)이 제시한 타당화 관련 4가지 측면(내용, 실제, 내적구조, 일반화)에 근거해서 Rasch 측정모형을 이용하여 타당화 작업을 실시하였다. 분석 결과, 문항 및 피험자의 신뢰도는 상당히 양호아였고, 내용타당도 관련하여 문항이 적절함을 보여주었다. 문항과 피험자를 한 로짓선상에서 비교하여 볼 때, 대체적으로 상위수준의 문항이 더 포함되어야 함을 보여주었다. 표준화 잔차를 사용한 Rasch 모형의 주성분 분석결과, 단일차원이 아님을 보여주었다. Conquest프로그램을 이용한 단일차원 Rasch 모형과 다차원 Rasch 모형 분석 결과. 다차원으로 보는 것이 더 적절한 것으로 나타났다. 유사한 내용의 문항들이 각각의 차원으로 이루어진 점도 있어서, 다문화 수용성은 내용영역에 따라 다른 반응이 가능하다는 점을 보여주고 있다. 이는 교육현장에서는 영역에 따른 프로그램운영의 필요성을 제시한다. 남녀 성차에 따른 문항 간에 있어서 차별기능문항이 존재하는지를 검증한 결과, 문항에 따른 차별기능문항이 나타났다. 추후 부적합한 피험자에 대하여 추가분석이 요구된다. This study was designed to validate a multicultural receptivity scale using the Rasch measurement model. Based on Park&Won`s instrument (2010), more comprehensive items (n=39) that reflect cognitive (n=14), emotional (n=12), and behavioral aspects (n=13) of multicultural receptivity were constructed and administered to students attending four-year universities, located in different parts of Korea. In validation processes. Messick`s (1989) ideas of content-, substantive-, construct-, and generalizability-related validity were applied to the product of a typical, unidimensional Rasch measurement model. Results showed that item and person reliabilities and content-related validity are high. However, when person and items are put on the same logit scale, mort items that capture upper level of ability need to be included. In additional, principal component analysis using Rasch standard residuals did not support the evidence of unidimensionality. Comparing both unidimensional and multidimensional Rasch models using Conquest program, the data supports the existence of multidimensionality. Groups of items formed multiple separate factors (dimensions), which indicates students responses to multicultural receptivity depends on characteristics of item content. This also suggests the possibility of implementing an area-specific multicultural education program. Additionally, several gender-related DIF were also identified. Further investigation may be needed to determine why some data did not fit the model.

박혜숙,Park, Hye-Sook 대한안면통증구강내과학회 2013 Journal of Oral Medicine and Pain Vol.38 No.1

구강점막질환과 성격유형과의 관련성을 규명하고자 경기도 지역 대학에 재학중인 학생 393명(평균연령 $21.2{\pm}3.1$세, 남자 184명, 여자 209명)을 대상으로 MBTI 검사와 설문조사를 실시하여 다음과 같은 결과를 얻었다. 1. 미각이상(p<0.05)과 구강 건조증(p<0.01)은 외향성(E)보다 내향성(I)에서 높은 빈도를 보였다. 2. 헤르페스성 구내염, 재발성 아프타성 궤양, 설염, 미각이상, 구강 작열감 증후군, 구강 건조증은 직관형(N)보다 감각형(S)에서 빈도가 높은 경향을 보였다. 3. 16가지 성격유형 중 NF를 포함하는 유형은 구강점막질환 증상 발생빈도가 높은 경향을 보였다. 4. 구강점막질환 증상 발생 시 대처 방법에 있어서는 저절로 낫기를 기다리며 그냥 둔다는 응답이 가장 많았으며(p<.0001), 이 응답자 중 헤르페스성 구내염(p<0.01)과 미각이상(p<0.05) 경험자의 경우 내향성(I)이 외향성(E)보다 많았다. 5. 성격이 예민한 편이거나 신경질적인 경우가 구강점막질환 증상 발생빈도가 높은 경향을 보였다. 따라서 구강점막질환 치료시 환자의 개별적인 성격 유형에 맞는 지침을 개발하는 것이 필요하리라 사료된다. The purpose of this study is to investigate the relationship between personality type and symptoms of oral mucosa disease. 393 college students completed the MBTI(Myers-Briggs Type Indicator) and a questionnaire and collected data were analyzed by SAS 9.2 program. The obtained results were as follows : 1. Dysgeusia(p<0.05) and xerostomia(p<0.01) occurred significantly more frequently in I type than E type. 2. Herpetic stomatitis, recurrent aphthous ulcer, glossitis, dysgeusia, burning mouth syndrome and xerostomia seemed to occur more frequently in S type than in N type. 3. Most symptoms of oral mucosa disease seemed to occur the most frequently in the type including NF among 16 types of personality of MBTI. 4. Most subjects had negative attitude in curing their symptoms of oral mucosa disease(p<.0001). Significantly more subjects with I type than E type had negative attitude in curing herpetic stomatitis(p<0.01) and dysgeusia(p<0.05). 5. Most symptoms of oral mucosa disease appeared to occur the most frequently in nervous or sensitive subjects. Therefore a guideline for the individual cure of oral mucosa diseases meeting personality type is necessary.

The purpose of this study was to evaluate the effect of specific head positions on the mandibular rotational torque movements in maximum mouth opening, protrusion and lateral excursion. Thirty dental students without any sign or symptom of temporomandibular disorders(TMDs) were included as a control group and 90 patients with TMDs were selected and examined by routine diagnostic procedure for TMDs including radiographs and were classified into 3 subgroups : disc displacement with reduction, disc displacement without reduction, and degenerative joint disease. Mandibular rotational torque movements were observed in four head postures: upright head posture(NHP), upward head posture(UHP), downward head posture(DHP), and forward head posture(FHP). For UHP, the head was inclined 30 degrees upward: for DHP, the head was inclined 30 degrees downward: for FHP, the head was positioned 4cm forward. These positions were adjusted with the use of cervical range-of-motion instrumentation(CROM, Performance Attainment Inc., St. Paul, U.S.A.). Mandibular rotational torque movements were monitored with the Rotate program of BioPAK system (Bioresearch Inc., WI, U.S.A.). The rotational torque movements in frontal and horizontal plane during mandibular border movement were recorded with two parameters: frontal rotational torque angle and horizontal rotational torque angle. The data obtained was analyzed by the SAS/Stat program. The obtained results were as follows : 1. The control group showed significantly larger mandibular rotational angles in UHP than those in DHP and FHP during maximum mouth opening in both frontal and horizontal planes. Disc displacement with reduction group showed significantly larger mandibular rotational angles in DHP and FHP than those in NHP during lateral excursion to the affected and non-affected sides in both frontal and horizontal planes(p<0.05). 2. Disc displacement without reduction group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening as well as lateral excursion to the affected and non-affected sides in both frontal and horizontal planes. Degenerative joint disease group showed significantly larger mandibular rotational angles in FHP than those in any other head postures during maximum mouth opening, protrusion and lateral excursion in both frontal and horizontal planes(p<0.05). 3. In NHP, mandibular rotational angle of the control group was significantly larger than that of any other patient subgroups. Mandibular rotational angle of disc displacement with reduction group was significantly larger than that of disc displacement without reduction group during maximum mouth opening in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group or degenerative joint disease group during maximum mouth opening in the horizontal plane(p<0.05). 4. In NHP, mandibular rotational angles of disc displacement without reduction group were significantly larger than those of the control group or disc displacement with reduction group during lateral excursion to the affected side in both frontal and horizontal planes. Mandibular rotational angle of disc displacement without reduction group was significantly smaller than that of the control group during lateral excursion to the non-affected side in frontal plane. Mandibular rotational angle of disc displacement without reduction group was significantly larger than that of disc displacement with reduction group during lateral excursion to the non-affected side in the horizontal plane(p<0.05). 5. In NHP, mandibular rotational angle of the control group was significantly smaller than that of disc displacement with reduction group or disc displacement without reduction group during protrusion in the frontal plane. Mandibular rotational angle of disc displacement without reduction group was signifi

This study was performed for the comparison of the therapeutic efficiency between 6-month (2HERZ/4HER) and 9-month (9HER) short-course chemotherapy under the programe conditions for pulmonary tuberculosis in terms of sputum AFB negative conversion rate, remedial interruption rate and cost effectiveness analysis. Two hundreds and ninty three patients treated with 9HER and 641 treated with 2HERZ/4HER had been discharged from 22 health centers in Seoul from May 1, 1993 to April 30, 1994. Seven hundreds and seventeen was subsequently analysed excluding 217 patients due to remedial interruption. The results : 1. Bacteriological negative conversion rate in 9HER regimen and 2HERZ/4HER regimen was 97.8% and 96.4% respectively(p>0.05). But the early treatment period, negative conversion rate in 2HERZ/4HER regimen was very higher than in 9HER regimen(p<0.01). 2. Remedial interruption rate for 9HER regimen and 2HERZ/4HER regimen was 34.1% and 13.6% respectively. The primary reason for the interruption was transfering to other clinics and this interruption was high within 3months. 3. Cost effectiveness for 2HERZ/4HER regimen was higher than 9HER regimen. The difference cost effectiveness ratio was 2.33 at the first sputum test and 1.69 at the last sputum test.

평균 유선선량 측정방법의 표준화 및 유방 두께, 실질양상과의 상관관계 분석

박혜숙,김희중,이창래,조효민,유아람,Park, Hye-Suk,Kim, Hee-Joung,Lee, Chang-Lae,Cho, Hyo-Min,Yu, A-Ram 한국의학물리학회 2009 의학물리 Vol.20 No.1

유방암은 우리나라 여성에게 발생하는 암 중에서 발병률이 높은 암이다. 따라서 유방자가진단, 임상적 검사, 유방 X선촬영 등과 같은 유방암 초기 검출검사는 중요하다. 이들 중 유방 X선촬영은 무자각증상 시기에 유방암 초기 검출을 위해 40대 이상의 여성들에게 매년마다 시행하기를 권고하고 있다. 그러나 유방의 유선조직은 방사선 민감성 조직이다. 이에 유방 X선촬영장치의 평가 중 평균 유선선량 측정은 매우 중요한 부분이 된다. 평균 유선선량의 직접측정은 어렵기 때문에 incident air kerma 측정, 적절한 변환계수 등을 적용하여 계산하게 된다. 따라서 본 연구의 첫 번째 목적은 평균 유선선량의 측정 방법의 표준화이다. 두 번째는 몬테칼로 시뮬레이션을 이용하여 평균 유선선량과 유방 실질양상 및 두께와 의 상관관계를 분석하고자 했다. 본 연구 결과, IAEA 가이드라인(CoP)에 따라 평균 유선선량 측정방법을 제시하였다. 전반적으로 우리나라는 유방촬영 시 받는 평균 유선선량이 식품의약품안전청 및 한국의료영상품질관리원에서 제시하는 3mGy 이하로 측정되었다. 측정된 평균 유선선량과 시뮬레이션된 평균 유선선량은 각각 1.7과 1.6 mGy로 큰 차이를 보이지 않았다. 시뮬레이션된 평균 유선선량은 주로 유방의 유선조직의 비율에 따라 의존한다. 유방의 glandularity 증가에 따라 낮은 에너지의 광자의 흡수가 증가하여 평균 유선선량도 증가하였다. 또한 유방의 두께가 두꺼울수록 평균 유선선량은 증가하였다. 결과적으로, 본 연구는 유방촬영의 진단 참고준위 확립을 위한 기초자료로 활용될 것이다. Breast cancer is the most common form of cancer among korean woman. Therefore, the early detection activities of breast cancer such as breast self-examinations, clinical breast examinations, mammography are important. A yearly mammography examination has been recommended for women aged 40 and older for the early detection of breast cancer in asymptomatic periods. However, the glandular tissue of breast is the most radiation-sensitive tissue, and the determination of average glandular dose (AGD) forms an important part of the quality control of the mammographic systems. Because of the difficulty of estimating AGD directly, it is often estimated from the measurements of the incident air kerma and by applying the appropriate conversion factors. The primary objective of this study was to standardize the method of measuring AGD. The secondary objective was to evaluate the relationships between AGD per various composition and thickness of the breast using Monte Carlo simulations. As a result, we standardized the method of measuring AGD according to International Atomic Energy Agency (IAEA) guidelines (CoP: an international code of practice). Overall, AGD for mammographic practice in Korea was less than 3.0 mGy recommended by the Korea Food and Drug Adminstration (KFDA) protocol, and Korean Institute for Accreditation of Medical Image (KIAMI). The measured and simulated AGD for a given condition were calculated as 1.7 and 1.6 mGy, respectively. For the AGDs obtained, there was no significant difference between them. The simulated AGD was dependent on the fraction of glandular tissue of the breast. The AGD increases with increasing of the breast glandularity due to increasing absorption of low energy photons. The AGD also increases as a function of breast thickness. In conclusion, the results of this study could be used as a baseline to establish a reference level of radiation dose in mammography.

치기공과 교육과정에서 다루어지는 보철 및 교정 치과기공물 제작 방법을 습득하기 위한 실습과목은 기능적인 영역이 강조되고 있으므로 학습자의 능력과 개인차를 충분히 고려하여 학습자의 다양한 요구에 부응할 수 있는 교수 학습모형이 필요하다. 이에 저자는 교수 1인이 다수의 학습자들을 대상으로 동시에 실습을 진행해 가는 상황에 대처할 수 있는 교수 학습법을 개발하였다. 시각적 효과에 익숙해져 있는 신세대 학생들의 특성을 고려하여 반복학습이 가능한 동영상을 활용한 온라인 실습교육과 오프라인 실습교육을 혼합한 단계적 모델링(Layers of Modeling)의 교수 학습모형을 시도하였다. 실습과정을 설명하는 동영상을 실습 일 주일 전에 e-클래스에 올려 예습하고 오도록 하고, 수업시간 교수자가 직접 실습과정을 시연하였다. 또한 전 주의 실기성적에 따라 실습실 내 학생들의 좌석배정을 하여 학업성취수준이 높은 학생과 낮은 학생을 짝지어 앉게 하여 개별실습 단계에서 동료지도법이 적용되도록 하여 학업성취수준이 낮은 학생에게 즉각적이고 개별적인 피드백이 자주 제공되도록 하였다. 수업 중에는 실습지침서에 실습결과물에 대한 자가평가를 하여 교수자의 점검을 받도록 하고 수업 후에는 동영상에서의 실습결과물과 비교, 분석하여 반성적 사고를 하도록 하였다. 그 결과 이러한 교수 학습모형은 학습자간 학업성취도의 격차를 좁히는 문제에 있어 해결의 가능성을 보여주어 학업성취도 향상에 긍정적인 영향을 주었다고 볼 수 있다. Let me introduce a teaching method to improve practice capacity in dental laboratary work. I applied theories of layers of modeling and reflection constituting cognitive apprenticeship and peer tutoring to my class. At internet uploading a file showing a practice procedure a week before the class of a course, I let students preview it. During the class I demonstrated the practice procedure in front of students. A superior student and an inferior student paired according to the previous practice grade and a feedback between a peer tutor and a peer tutee was activated. Late in the class, a student self-evaluated his own practice result and had a check of a professor. Finally he compared his own practice result with that in the file uploaded at internet and reflected. This teaching method led to improvement in students' satisfaction and efficiency of learning.

한국어의 음절말 내파음의 후두조절 -화이비스코프 및 근전도에 의한 관찰-

박혜숙,Park, Hea-Suk 대한후두음성언어의학회 2005 대한후두음성언어의학회지 Vol.16 No.1

It is known that Korean stop consonants in syllable-initial position are of three types : lax, aspirated and forced (or unaspirated). In syllable-final position, however, these three different types are merged to a single type with the same place of articulation, although the original three-way distinction is preserved in Korean orthographic (Hangul) system. Thus the syllable-final stops are phonetically realized as voiceless "applosives" which are characterized by the absence of oral release. The aim of the present study is to investigate the laryngeal adjustments for these syllable-final stops in various phonological conditions by using fiberscope, and, is to further investigate electromyographically the laryngeal adjustments for Korean stops both in the syllable-initial and final positions in various phonological conditions. The results can be summarized as follows : 1. In the case of syllable-initial stops, the glottal widths in each three types of the Korean stops during the articulatory closure are clearly different. And the pattern of thyroarytenoid(VOC) activity appeared to characterize the three different types of Korean stops. 2. The basic laryngeal feature of the Korean syllable-final applosives is characterized by a small degree of glottal opening which begins at or slightly after the oral closure. 3. In the case, syllable-final stop followed by the copula "ita", the syllable- final stop is pronounced as the stop consonant at the initial position of the following syllable containing the vowel[i], the underlying features of three-way distinction for the stops in the Korean orthographic(Hangul) system being manifested at the laryngeal adjustment. 4. In the case of the final applosives followed by the initial stops and fricatives, the laryngeal feature of the final applosives appears to be assimilated by that of the following consonant irrespective of the difference in the place of articulation, as far as the glottal abduction/adduction is concerned. It is clearly demonstrated in the case of syllable-initial stop that thyoarytenoid(VOC) activity is suppressed for the production of the stop consonants in question, the degree of which is slightest for the forced type and most marked for the aspirated type, while it is moderate for the lax type.
