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.

Recently, the number of obese people have been increasing due to westernized diets and increased sedentary activity. In particular, obese adolescent have been newly recognized as having significant health problems. This study focuses on determining the gender difference of obese adolescents through implementation of a structured questionnaire on general characteristics, attitudes toward dieting, eating habits and emotional depression due to obesity. Data collection was carried out by 291 students in attendance at 3 high schools in Pusan from 11. 2. 1998 to 11. 30. 1998. The targets were 148 boys and 143 girls who were judged as obese in the school's physical check-up. The test of reliability of this research was calculated by chronbach's α. Data analysis was managed by computer and statistics by SPSS/WIN. The results of the survey are as follows: 1. For the questionnaire regarding attitudes toward dieting which include 28 items, 10 out of 28 items (about 36%)showed gender difference. 2. For the questionnaire regarding eating habits which include 17 items, 5 out of 17 items (about 30%)showed gender difference. 3.For the questionnaire regarding emotional depression about obesity, 30.6% of boys and 27.3% girls answered but no statistical significance. The results of this survey indicated that this study will be important as a good guideline for treating obese adolescents. It is hoped that much more research on gender difference in obese adolescents will be implemented in the future. In addition, the development of effective treatments for obesity should be based on the gender of the adolescent.

유효검출양자효율과 선량을 이용한 소아 흉부 X-선 영상의 기술적인 인자에 관한 조사

The purpose of this study was to investigate the effect of various technical parameters for the dose optimization in pediatric chest radiological examinations by evaluating effective dose and effective detective quantum efficiency (eDQE) including the scatter radiation from the object, the blur caused by the focal spot, geometric magnification and detector characteristics. For the tube voltages ranging from 40 to 90 kVp in 10 kVp increments at the FDD of 100, 110, 120, 150, 180 cm, the eDQE was evaluated at the same effective dose. The results showed that the eDQE was largest at 60 kVp when compares the eDQE at different tube voltage. Especially, the eDQE was considerably higher without the use of an anti-scatter grid on equivalent effective dose. This indicates that the reducing the scatter radiation did not compensate for the loss of absorbed effective photons in the grid. When the grid is not used the eDQE increased with increasing FDD because of the greater effective modulation transfer function (eMTF). However, most of major hospitals in Korea employed a short FDD of 100 cm with an anti-scatter grid for the chest radiological examination of a 15 month old infant. As a result, the entrance surface air kerma (ESAK) values for the hospitals of this survey exceeded the Korean DRL (diagnostic reference level) of $100{\mu}Gy$. Therefore, appropriate technical parameters should be established to perform pediatric chest examinations on children of different ages. The results of this study may serve as a baseline to establish detailed reference level of pediatric dose for different ages. 본 연구에서는 피사체에 의한 산란, 초점에 의한 흐림, 기하학적 확대도 그리고 검출기의 특성이 반영된 유효검출양자효율(effective detective quantum efficiency, eDQE)과 유효선량을 평가하여 소아 흉부 X선 촬영 시 선량의 최적화를 위한 조사조건의 영향을 평가하였다. 100, 110, 120, 150, 180 cm의 FDD (focus-to-detector distance)일 때 관전압을 40 kVp에서 90 kVp까지 10 kVp씩 증가시켜가며 동일한 유효선량일 때 eDQE를 평가하였다. 그 결과 eDQE는 다른 관전압과 비교 시60 kVp에서 가장 높은 값을 보였다. 특히, 동일한 유효선량일 때 그리드가 없을 경우 상대적으로 매우 높은 eDQE를 나타냈다. 이는 그리드에 의한 산란선의 감소가 그리드에서 흡수된 유효 광자의 손실을 보상하지 못하기 때문이다. 그리드 가 없을 경우 FDD가 증가할수록 향상된 유효변조전달함수(effective modulation transfer function, eMTF)로 인하여 eDQE는 증가하였다. 국내 대형병원들의 대부분은 15개월 소아의 흉부 X선 촬영 시 그리드와 함께 100 cm의 짧은 FDD를 사용하고 있다. 그 결과 대부분의 경우는 국내 환자선량권고량(diagnostic reference level, DRL) $100{\mu}Gy$을 초과하였다. 이는 5세 소아 흉부 X선 촬영 시 150 cm에서 180 cm 사이의 긴 FDD를 사용하지만, 15개월을 모사하고 있는 표준 소아팬텀의 흉부 X선 촬영의 경우 100 cm의 짧은 FDD를 사용했기 때문이다. 따라서, 나이에 따른 소아의 흉부 X선 촬영을 시행하기 위한 적절한 조사조건이 확립되어야 한다. 본 연구 결과는 나이에 따른 소아 선량의 권고량을 설립하는데 기초자료로 활용될 수 있을 것이다.

배경 및 목적 : 한국 구개열환자에게는 된소리 자음(농음0의 구음산출의 난도가 높다는 것은 임상적으로 잘 알려져 있다. 그러므로 본 연구에서는 한국 구개열 환자에게 있어서 난도가 높은 농음의 산출 메커니즘의 기본적 요소를 규명하므로서 언어치료의 새로운 방법모색에 기여하고져 하였다. 연구방법; 비강자음에 후속된 3종의 어두 파열자음 산출시의 구개범거근의 근활동 양상의 차이를 비교검토하므로서 농음의 산출특성을 검색하고져 하였다. 관찰기록 방법은 근전도는 유구침금전극(hooked wire electrodes)을 구강내로부터 경점막적으로 유도하였다. 연구결과 : 격음과 농음의 파열자음에서 평음보다 높은 구개범거근의 근활동이 관찰되었으나 격음과 농음 사이에선 유의미적인 차이는 보이지 않았다. 결 론 : 금후의 과제로는 피험자를 늘려 재확인을 하는 일, 및 농음과 격음의 변별요소에 관해 더욱 검토할 필요가 있는 것이 시사되었다.

폐결핵 재발 환자의 약제 감수성과 재발 간격에 관한 단면 연구 - 서울시 일부 보건소 등록 환자를 중심으로

박혜숙,하은희,위자형,강지용,Park, Hye-Sook,Ha, Eun-Hee,Wie, Cha-Hyung,Kang, Ji-Yong 대한예방의학회 1996 Journal of Preventive Medicine and Public Health Vol.29 No.1

The purpose of this study was examine the general characteristics of relapsed pulmonary tuberculous patients (i.e. age, sex, weight, occupation, previous forms of treatment, drug sensitivity, and the frequency of relapse) in order to improve future treatments of tuberculosis as well as to perpetuate health education. The data was obtained from the medical records of 186 relapsed pulmonary tuberculosis patients who were registered for treatment at various public health offices in Seoul during the year of 1994. The major findings obtained from the study were as follows; 1) The male to female ratio of relapsed pulmonary tuberculous patients was about 7:3, more specifically 23.7% of the men and 30.9% of the women were between 20 and 29 years of age. 2) Comparing initial less aggravated states to relapsed states, patients with minimal X-ray findings later proved moderately advanced X-ray findings. Furthermore, patients with negative sputum AFB findings later proved positive sputum AFB findings. 3) Of the 186 patients studied, 91.9% suffered, relapse and 8.1% suffered 2 or more relapses. Of the patients who suffered at least 1 relapse, 54.8% received short-term treatment, 26.9% received long-term treatment, and 18.3% received treatment of an unknown during their initial tuberculosis treatment periods. 4) fifty five point four percent of the patients had no reaction to the drug treatment(not available), 25.9% of the patients had sensitive reaction to the drug treatment, 18.7% of the patients had resistant reaction to the- drug treatment. Drug resistance was higher in patients that exhibited positive X-ray findings as well as in patients that exhibited positive sputum AFB findings. furthermore, patients receiving treatment of an unknown nature(35.5%) exhibited higher drug resistance than those receiving short-term treatment(13.6%) and long-term treatment(17.0%). 5) Of the 160 patients who suffered relapses, 8.8% suffered a relapse within 1 year after treatment and 91.2% suffered a relapse at least 1 year after treatment. Furthermore, our study showed that women, under 30, who received short-term treatment and encounterd complications during their primary treatment suffered relapses faster than any other groups studied. In addition, minimal X-ray findings and sputum AFB findings were not correlated to the time relapse occured. Therefore, the seater efforts are needed to prevent relapsed pulmonary tuberculosis.
