In this study, radiation doses of major organs in various postures in lower extremity teleography were measured and compared to investigate the utility of the test methods. Ten adult males who underwent lower extremity teleography at a tube voltage of 73 kVp, tube current of 32 mAs, and SID of 180 cm. Using rando phantom, glass dosimeter was attached to the eye lens, thyroid gland, and genital gland to measure the radiation dose in each area 5 times in each anteroposterior posture and posteroanterior posture. The results were compared and analyzed through Paired T-test. The images from the anteroposterior posture and posteroanterior posture were evaluated through the blind test on a scale of 5. As a result, the posteroanterior method could reduce the dose than the anteroposterior posture method: less dose for the eye lens by 6%, thyroid gland by 6%, and genital gland by 26%. Since there was no significant difference in image evaluation, the posteroanterior posture is considered better than the anteroposterior posture in lower extremity teleography.

The purpose of this study was to analyze the direct measurement data of 40-59 year old middle-aged men from Size Korea's 7th anthropometric survey, and to identify the body shape characteristics and to type the body shape of middle-aged men. Through this, this study aimed to provide basic data necessary for the clothing patterns of middle-aged men with excellent fit. The data was SPSS Ver. 24.0 program analysis. Factors extracted six including body horizontal, vertical, shoulder, waist front length, leg thickness, and shoulder deflections. The body shape of middle-aged men was classified into three types. Type 1 had a thin body circumference, a narrow width, a low height, a short waist front length, and a thin ankle and calf. Type 2 had a high body height, a long waist front length, a normal circumference and width, a thick ankle, a calf, and a sagging shoulder. Type 3 had a large body circumference, a wide body, a wide shoulder, and a long waist front length. A prominent feature of the changes in body shape of middle-aged men is the increase in the circumference and thickness items due to abdominal protrusion and fat accumulation. Therefore, pattern design according to these physical characteristics is considered to be necessary.

본 연구는 3D레이저 스캔 방식으로 계측된 인체 데이터를 대상으로 하여 인체의 여러 동작들에 대한 애니메이션 모듈 구현을 목표로 하였다. 이를 위하여 애니메이션 회전을 위한 기준점인 인체의 골격 기준점을 추출하고 추출된 기준점을 이용하여 골격을 잡고 각 골격에 따른 계층트리를 구성하였다. 구성된 계층트리의 골격에 해당되는 오브젝트 정점들을 골격과 연결하고 주어진 애니메이션 3차원 정점들에 행동 패턴을 적용하여 스캔데이터에 애니메이션을 구현하였다.

In the field of pediatric dentistry, comparison and analysis of cephalogram values of children are important fir evaluation of growth and development, and are essential to evaluate the craniofacial form and growth pattern for early diagnosis of malocclusion. For this, cephalographic norm values are important, but not many studies on the primary dentition exist. To compare the past norm values of normal occlusion in the primary dentition with current norms, preschool children, 4 to 5 years of age, with normal occlusion in the primary dentition who visited our hospital were examined. Among these children, 46 children with normal facial form and developmental status were chosen for evaluation of cephalogram values. The following results were as follows: 1. For skeletal values, the angular values showed no significant differences between males and females, and the linear values were generally greater in males than females. 2. SNA was $81.3^{\circ}$, SNB was $76.6^{\circ}$ and ANB difference was $4.7^{\circ}$. 3. The ratio for Mandibular body length to Anterior cranial base length was 0.9 : 1 for both male and female and the ratio for posterior facial height to anterior facial height was 61.4 % for male, 62.0 % for female. 4. For dental values, IMPA was $84.2^{\circ}$ and UA to SN was $90.8^{\circ}$. 5. The upper lip to Ricketts esthetic line was positioned 2.6 mm anteriorly, and the lower lip to Ricketts esthetic line was positioned 2.5 mm anteriorly.
