MCNP 코드를 사용하여 IAEA에서 권고하고 있는 물팬톰과 미국내 선량계 성능시험 프로그램에서 규정하고 있는 PMMA 팬톰내 0.07mm 및 10mm 깊이에서의 환산인자 H(d)/Ka을 계산하였다. 계산은 팬톰의 한면에 수직으로 입사하는 단일에너지 광자의 확장정열빔에 대해 수행하였다. 결과는 팬톰내에서 정의되는 선량당량으로 선량계를 교정할 때 환산인지로 사용될 수 있다. MCNP code was used to calculate conversion factor H(d)/Ka at the depths of 0.07 and 10mm within a water phantom recommended by IAEA and within a PMMA phantom required by the US dosimeter proficiency testing programmes. The calculations were performed for an expanded parrallel beam of monoenergetic photons of perpendicular incidence on one faces of the phantom. The results can be used as conversion factor in calibrating individual dosemeters in terms of the dose equivalent quantities defined directly in the phantom.

The purpose of this study was (1) to determine the prevalence of some causes by which dental occlusion might be affected, (2) to determine the prevalence of malocclusion, and types of molar, vertical incisor and horizontal incisor relationships, and (3) to examine the sex difference in the prevalence ratios, and (4) to determine the between-examiner differences in assessing types of dental occlusion. The material consisted of 1281 males and 811 females, total 2091 persons, aged 17 to 21 years. Two examiners who were graduate students in the orthodontic course, examined independently dental occlusion of the material. Before calculating the statistics, the subjects consisted of 156 males and 164 females, total 320 persons, having any one or more causes suspected to affect dental occlusion, was eliminated. Then the remained subjects, 1124 males and 647 females, total 1771 persons, were assessed. The results were as follows 1. The prevalence of some causes by which dental occlusion might be affected was 15.32 percent. The missing rate of any one or more first molars was 8.85 percent, that of any one or more teeth positioned anterior to the first molar was 3.83 per cent. The prevalence of crossbite of the first molar was 0.48 per cent, that of retained primary teeth was 0.77 percent, and that of orthodontic treatment was 0.43 per cent. 2. The rate of between-examiner difference was 12.53 per cent in assessing the types of molar relationship, 18.86 percent in assessing the types of horizontal incisor relationship, and 26.37 percent in assessing the types of horizontal incisor relationship. 3. There was no sex difference in the prevalence ratios of the types of molar relationship. The prevalence of Class 1 molar relationship was 80.91 percent, that of Class Ⅱ was 5.03, that of Class Ⅱ subdivision was 4.01, percent, that of Class Ⅲ was 5.99 percent and that of Class Ⅲ subdivision was 4.07 percent. 4. In the prevalence of the types of horizontal incisor relationship, there were no sex differences except that of Class Ⅱ division 2. The prevalence of Class 1 horizontal incisor relationship was 73.12 percent, that of Class Ⅱ division 1 was 12.03 percent, that of Class Ⅱ division 2 was 6.58 percent in male and 4.33 percent in female, and that of Class Ⅲ was 9.09 percent. 5. In the prevalence of the types of vertical incisor relationship, there were no sex differences except that of deep bite, The prevalence of open bite was 2.20 per cent, that of edge-to-edge bite was 9.15 percent, that of normal bite was 76.34 percent, and that of deep bite was 14.15 percent in male and 9.12 percent in female. 6. There was no sex difference in the prevalence of malocclusion the prevalence of malocclusion was 82.67 percent and that of normal occlusion was 17.33 percent. 7. There was a tendency that when Class 1 molar relationship changed to Class Ⅱ, incisor relationships were to be larger overjet or upright upper incisors and deep bite, but when that changed to Class Ⅲ molar relationship, these were to be cross bite and openbite.

In this paper, we propose a watermarking algorithm of multiresolution watermarking based on wavelet transform for digital images. Watermark insertion is add to pseudo random sequences to the wavelet coefficients at the high and middle frequency band of the discrete wavelet transform. Instead of previous method, proposed multiresolution watermark decoder that allows efficient identification of the embedded a bank of watermarking key without prior notice of it. Proposed detection method aims at ensuring the maximum exactitude in the detection of the owner identification key and, minimizing the number of false positive detection.

This paper presents an efficient technique for digital watermark robustness against filtering and scaling attack. It inserted the watermark in low frequency portion of the wavelet-transformed image and it uses from communication the interleaving method in the proposed method it applied. The Interleaving method orders a data bit row at schedule unit the rearrange. With that result in instantaneous noise when the part bit in data bit row center is lost, it the recover it does as a role. And in order watermark to do the coefficient values of low frequency domain from in transformed domain of 4 portion of original image it does and every the pixel the linearly it does and bit it expands. Experimental results demonstrate the high robustness of the method to such image degradations as Lowpass filtering, Median filtering and Rescaling transform.

목 적 : 근로자 건강증진을 위한 사업장 건강증진 사업 프로그램 기획실에 건강 위험요인을 평가하고 근로자 특성에 4따른 행동변화단계를 조사하여 행동 변화단계에 따른 성공적인 근로자 건강증진전력을 위한 기초자료를 제공하고자 본 연구를 진행하였다. 방 법 : 경인지역이 중소 기업 제조업체 근로자 282명을 대상으로 설문조사를 수행하였으며, 일반적 특성에 대한 조사, 건강위험평가, 위험요인에 대한 행동변화단계를 조사하였다. 결 과 : 건강위험평가에서 흡연자는 남자 근로자에 서 65.7 %, 규칙적인 운동을 하지 않는 남자 근로자는 70.5 %, 여자 근로자는 86.1 %이었고 음주는 남자 근로자의 78.6 %, 여자 근로자인 50 %이었고 과음은 남자 근로자의 29.5 %, 여자 근로자의 11.1 %이었다. 건강한 생활습관으로의 행동변화단계로 계획전단계, 계획 단계, 실천단계, 유지단계 등 4개의 단계로 보면 근로자에서의 금연에 대하여 각각 40.5 %, 23.7 %, 12.1 % 및 23.7 %, 운동에 대하여는 18.4 %, 37.6 %, 17.7 % 및 26.3 %, 음주하였던 사람중 절주에 대하여는 20.9 %, 15.4 %, 10.0 % 및 53.7 %이었다. 흡연을 하는 보건관리자의 행동단계가 일반근로자 보다 유의하게 많았다. 운동에 대해서는 근로자중 50세 이상과 생산직 근로자에서 계획전단계가 다른 근로자보다 유의하게 많았다. 결 론 : 이상의 결과로 대부분의 근로자가 금연을 제외하고는 건강한 생활습관으로의 행동변화를 원하는 것을 알 수 있었으며 근로자의 특성에 따라 행동 변화단계가 다르므로 이를 고려한 다양한 건강증진 프로그램을 개발함으로써 참여율 및 성공율을 높일 수 있으리라 사료된다. Objectives : This research attempts to investigate the relationship between health risk factors and workers' behavioral changes based on individual worker's characteristics to allow the development of more effective health promotion programs in businesses places. Methods : A questionnaire survey was conducted with 282 workers employed in small to medium sized enterprises in the Kyong-in area of Korea. The questionnaire was composed of general characteristics, a health risk assessment and an evaluation of the stage of behavior change for health promotion strategy in the workplace. Results : The health risk assessment revealed that 65.7 % of male workers smoke, 70.5% of male workers do not exercise on a regular basis, 86.1 % of female workers do not exercise at all, and 78.6 % of male workers and 50 % of female workers drink alcohol. In addition, the survey identified that 29.5% of male workers are addicted to excessive drinking, as are 11.1% of female workers. Based on the four stages of behavioral changes that lead to health, the pre-contemplation stage, contemplation stage, action stage, and maintenance stage, 40.5 %, 23.7 %, 12.1 % and 23.7 % of workers are in these stages, respectively, with regards to quitting smoking. As for regular exercises, 18.4 %, 37.6 %, 17.7 %, and 26.3 % of workers belong to each stage, respectively. As for moderation in drinking, 20.9 %, 15.4 %, 10.0 %, and 53.7 % are in each stage, respectively. The rate of health managers in the active stage of quitting smoking is significantly higher than that of general workers. Among the workers who do not exercise on a regular basis, workers over 50 years-old and blue color workers are more common in the precontemplation stage than any other worker groups. Conclusions : The results of this study suggest that the stages of behavioral change vary with worker characteristics. An awareness of the effects of the high risk factors is essectial for promoting workers' attendance in health promotion programs.

正常및 異常分娩中 母體와 臍帶血漿의 β-endorphin 및 ACTH値의 變動에 關한 硏究

鄭求烈,李揆玩,李珉載,洪性鳳 고려대학교 의과대학 1987 고려대 의대 잡지 Vol.24 No.1

β-endorphin and adrenocorticotrophic hormone (ACTH) are derived from the same precursor protein and they have been implicated as the modulators of pain during the labor process. To investigate their possible role during labor this study was undertaken to determine the levels of β-endorphin and ACTH during labor and delivery in healthy term pregnant women and their neonates after delivery. β-endorphin and ACTH were measured by radioimmunoassay in 22 spontaneous labors, 14 elective cesarean sections and 7 emergency cesarean sections during early and late labor, and after delivery. The results obtained are as follows: 1. In cases of spontaneous vaginal delivery and emergency cesarean section, maternal plasma β-endorphin and ACTH levels were significantly increased during late labor and remained and continuously elevated during the first postpartum hour. 2. In cases of elective cesarean sections, maternal mean plasma levels of β-endorphin and ACTH were significantly lower than levels in spontaneous vaginal deliveries and emergency cesarean sections. 3. There was a significant correlation between meternal plasma β-endorphin and ACTH levels during labor. 4. Umbilical arterial β-endorphin levels in newborn infants after spontaneous vaginal delivery and emergency cesarean section were significantly higher than levels in infants born by elective cesarean section, but only spontaneous vaginal deliveries showed higher umbilical arterial ACTH levels in newborn infants than infants born by elective cesarean section. 5. There was no relationship between meternal and umbilical cord plasma β-endorphin and ACTH. There was not significant correlation between umblical cord plasma β-endorphin and ACTH levels, and fetal weight and placental weight. 6. There was no correlation betwen umbilical arterial pH and Apgar score by mode of delivery, but statistical significance was found to exist in the umbilical arterial pH of emergency cesarean sections and elective cesarean sections. Present studies suggest that β-endorphin and ACTH are significantly increased during late labor due to stress and pain, and hypoxia may be important physiologic stiumuli controlling the release of β-endorphin and ACTH in the human fetus.
