This study tried to suggest a drafting method to draft tight fit torso patterns suitable for adult males with a sway back somatotype and a bend forward somatotype by setting and distributing the ease through the completion of the somatic surface pattern using the 3D body surface segment method. It was intended to be presented as a drafting method. As for the research method, the suitability of the somatic surface patterns and the tight fit torso patterns were confirmed by the evaluation of virtual wear, and the patterns were modified and supplemented. The research results are as follows. In the first evaluation of the tight fit torso patterns, the average, for 55 evaluation items, was 3.92 points for the sway back somatotype and 3.89 points for the bend forward somatotype. In the second evaluation, the bend forward somatotype was 4.51 points and the sway back somatotype was 4.62 points. The chest circumference ease amount for the bend forward somatotype and the sway back somatotype are 6.5% (6.8 cm) and 7% (6.8 cm) of the chest circumference, respectively, and the distribution of the front and back ease is the same at 4:6 (2.72 cm:4.08 cm). The waist circumference ease amount is 6.5% (5.8cm) and 6.5% (5.6 cm) of the waist circumference dimensions, and the distribution of the front and backease are 5:5 (1.45 cm: 1.45 cm) and 4:6 (2.24 cm: 3.36 cm), respectively. The completed tight fit torso patterns were converted into institutional formulas and presented as a drafting method.

During the past few years it has been proposed that lithium clearance can be used as a reliable measure for the outflow of tubular fluid from the proximal tubule. This study was aimed to characterize the inflow dependent reabsorption of Na in renal tubule beyond the proximal tubule. For this purpose, lithium clearance was used as a measure for the inflow from the proximal tubule and the changes in reabsorption fraction of Na and water were determined in rabbits. Rabbits were pretreated with hypotonic saline solutions for an hour (50 mM/L NaCl, 20 ml/hr/kg). And then a hypertonic solution of 500 mM/L NaCl (20 ml/kg) was administered intraperitoneally in conjunction with a bolus of LiCl solution (2 mM/kg, i.v.) for conditioning the $C_{Li}$ and urine flow rate. To rule out the effect of $Li^+$ on tubular functions, a bolus of NaCl solution (2 mM/kg, i.v.) was administered. Fifteen, thirty, and sixty minutes after injection of hypertonic saline arterial blood and urine samples were taken. Urinary and plasma concentrations as well as urinary output of $Li^+,\;Na^+\;and\;K^+$ were measured. From these $C_{Li},\;C_{Na}$ and the reabsorption fraction of Na and water $(Fr_{Na}\;&\;FrH_2O)$ were calculated. These results were compared with those from control groups in which the same amount of isotonic saline (145 mM/L NaCl) and of 15% dextran solution were administered in the same way as that in experimental group. Followings are the results obtained. 1) The plasma concentration of $Na^+$ in rabbits injected with hypertonic saline reached the peak value after 15 min and thereafter no significant change was observed. Hematocrit values did not show any change, while urinary excretion of $Na^+$ increased markedly during the first 15 min and decreased thereafter. These results were not affected by an injection of a small amount of LiCl. 2) The clearances of $Li^+,\;Na^+\;and\;K^+$ in rabbits injected with hypertonic saline and LiCl solution decreased. 3) In spite of the variation in $C_{Li},\;Fr_{Na}$ did not show any significant change while $FrH_2O$ increased gradually. 4) $C_{Li}$ decreased also in rabbits received isotonic saline. $Fr_{Na}$ tended to be higher than that in hypertonic saline group, while $FrH_2O\;and\;Fr_{Na}$ did not associated with the decrease in $C_{Li}$. 5) $C_{Li}$ of the rabbits received dextran solution fluctuated persistently and $Fr_{Na}\;and\;FrH_2O$ did not change in along with $C_{Li}$ although $Fr_{Na}$ had a tendency to be higher than that in hypertonic saline group. 6) From the above results it was concluded that: (a) In rabbits with normal body store of $Na^+$, the $Fr_{Na}$ of renal tubule beyond proximal tubule. calculated from $C_{Li}$ as a measure of inflow from proximal tubule is constant in spite of variations in $C_{Li}$. (b) The $FrH_2O$ calculated from $C_{Li}$ is dependent largely upon ADH rather than inflow from proximal tubule. (c) When there is a decrease in plasma $Na^+$ concentration or ineffective body fluid. $Li^+$ reabsorption may occur in the thick segnent of Henle's loop and hence the determination of $Fr_{Na}$ and $FrH_2O$ will not be easy one, but $Fr_{Na}$ is constant under the same experimental conditions.

목적 : 현재 PET/CT에서 CT의 역할은 단순히 감쇠 보정만을 위한 도구에서 진단을 위한 도구로 그 역할이 발전해 가고 있다. 따라서 양질의 CT 영상을 얻기 위한 정맥 조영제의 사용과 고선량의 CT 촬영이 요구되고 있으며 최근 조영제가 감쇠 보정한 PET 영상에 크게 영향을 미치지 않는다는 보고가 나오고 있다. 이에 본 연구에서는 고선량 CT에서 정맥 조영제의 사용이 감쇠 보정에 미치는 영향을 알아보았다. 대상 및 방법 : 총 13명의 환자에게 PET/CT 검사를 시행하였다. $^{18}F$-FDG를 주사하고 1시간 후에 촬영하였고, 첫 번째로 조영제의 사용 없이 CT(NECT-120 kVp, 130 mAs)를 촬영하고 이어서 바로 조영제를 사용하여 CT(CECT)를 촬영한 후 PET을 시행하였다. 각 환자마다 NECT와 CECT에 의해 각각 보정된 PET 영상에서 10곳의 신체 부위(병변이 없는 폐첨부, 폐기저부, 상행대동맥, 간의 상부 및 하부, 비장, 척추, 대퇴골두, 장요근과 10번 척추와 척추 인접 근육) 에서 HU와 maxSUV 값을 구하였고, 종양과 임파선 병변의 값도 함께 측정하였다. 결과: 조영제를 사용하였을 때 국소적으로 섭취가 증가된 곳은 관찰되지 않았다. 총 130개의 정상 조직의 maxSUV값을 측정하여 비교하였을 때, 조영제를 사용한 군과 사용하지 않은 군의 평균 maxSUV 값은 각각 $1.1{\pm}0.5,\;1.0{\pm}0.5$이고 두 군 사이에 p<0.001로 통계적으로 유의한 차이를 보였다. 정상 조직에 대해 Bland-Altman 분석을 시행하였을 때 일치의 한계 범위는 $0.1{\pm}0.3$ 이었다. 10개의 대상 영역 중 폐첨부, 폐하부, 상행대동맥, 간의 상부와 하부, 비장에서 maxSUV 값이 두군에서 유의한 차이(p<0.05)가 있었다. 총 39개 병변의 maxSUV 값을 측정하여 비교하였을 때, 조영제를 사용한 군과 사용하지 않은 군의 평균 maxSUV값은 각각 $4.7{\pm}2.0,\;4.4{\pm}2.0$이고 두 군 사이에 p<0.001로 통계적으로 유의한 차이를 보였다. 병변에 대해 Bland-Altman 분석을 시행하였을 때 일치의 한계 범위는 $0.4{\pm}0.8$ 이었다. 결론: 조영제로 인해 maxSUV의 값은 증가되었으나 정상 조직과 병변에서 일치의 한계 범위가 매우 좁았다. 따라서 진단용 고선량 CT를 이용한 PET/CT 촬영 시에 조영제의 사용이 임상 상황에서 판독에 큰 영향을 미치지 않는 것으로 생각된다.

본 연구는 철봉운동에서 기본이 되는 동작인 몸펴 한번 뒤돌아 내리기 동작을 단계적으로 분석한 후, 이를 토대로 하여 현재 시합상황 중 가장 널리 사용되는 응용동작인 몸펴 두 번 뒤돌아 내리기 동작과 몸펴 두 번 뒤돌며 한번 비틀어 내리기 동작의 운동학적 분석을 수행하여 개개분절 간의 상호작용을 해부학적 3차원 각운동과 각속도로 설명하고 이해할 수 있는 운동학적 자료를 제시하는데 있다. 피험자들은 현재 K대학교에 재학중이며 대학 대표선수인 남자 기계체조 선수 7명을 선정하였으며, 연구에 사용된 인체의 모델은 Zatsiorsky와 Seluyanov(1983, 1985)이 사용한 16개의 분절로 이루어진 인체의 모델을 사용하였다. 신체무게중심이 이동방향을 설명할 수 있는 투사각도 및 투사속도는 공중동작의 회전수가 증가할수록 신체무게중심이 투사되는 각도가 증가되며, 이렇게 증가된 신체무게중심의 투사각도는 신체무게중심의 최고점을 증가시키는 경향을 보였다. 3차원 투사속도를 살펴본 결과 Z방향(수직방향)은 공중돌기 회전수가 증가할수록 증가하는 경향이 나타났으나, 운동진행 방향인 Y방향 속도와 좌우측 기울기를 설명할 수 있는 X방향 속도에서는 의미 있는 차이를 보이지 않았다. 철봉 내리기 공중동작에서의 신체분절 및 각도 변화도 중요하지만 각운동량을 만들어내기 위한 동작준비구간의 각도 변화가 더욱더 중요하다고 할 수 있다. 즉, 상체가 철봉 아래 봉과 수직될 때부터 릴리즈 순간까지의 각도 변화에 주목해야 하는 데, 회전수가 증가할수록, 어깨관절 각도와 엉덩관절 각도 변화가 두드러지게 나타나 준비구간의 추기기 동작(Whip swing)의 주된 관절로 작용을 한다. 관성좌표계에 대한 상체의 움직임을 나타내는 3차원 방향의 각도 즉, 뒤돌기(somersault)각도, 틀기(twist)각도 그리고 기울기(tilt)각도로 설명이 되는데, 본 연구의 결과 릴리즈시 뒤돌기 각은 세가지 내리기 동작 유형에 따라 평균 57,7도, 38.8도 그리고 39.7도로 나타났으며, 기울기 각은 평균 -1.5도, -5.4도 그리고 -8.4도로 유의한 차이를 보이고 있으며, 틀기각도는 평균 13.4도, 10.6도 그리고 23.3도로 몸펴 두번 뒤돌며 한번 비틀어 내리기 경우 가장 큰 수치를 나타냈다.

본 연구는 세계적인 선수를 대상으로 남자 기계체조 도마 종목에서 로페즈 기술을 수행했을 때 성공 동작과 실패 동작에 따라 운동학적 차이를 비교 분석하였다. 연구대상은 올림픽 금메달리스트 YHS 선수(나이: 27세, 신장: 160cm, 체중: 53kg중)이였고, 14대의 적외선 고속카메라를 이용하여 도마 동작을 촬영하였다. 원하는 동작 자료획득과 분석을 위해 19mm 반사 마커 26개를 해부학적 주요지점에 부착시켰고, 15개 분절 신체모델을 사용하여 운동학적 변인 계산을 실시하였다. 분석 결과 첫째, 구름판 접촉구간에서 성공 동작의 소요시간이 실패 동작보다 길었으며, 성공 동작은 슬관절의 가동범위를 실패 동작보다 크게 하였다. 둘째, 제1비약에서 성공 동작과 실패 동작의 소요시간은 동일하였다. 성공 동작은 실패 동작보다 짧은 수평이동을 했으며, 높은 수직위치와 도마 착지각을 보였다. 셋째, 도마 접촉구간에서 성공 동작의 소요시간이 실패 동작보다 짧았다. 성공 동작은 도마접촉 순간에 실패 동작보다 좌측 견관절각을 크게 하였다. 넷째, 제2비약에서는 성공 동작의 소요시간이 실패 동작보다 길었으며, 긴 수평이동을 나타냈다. 성공 동작은 도마이륙 순간 우측 견관절각을 크게 하였고, 비틀기 각속도는 빨랐다. 종합하면 YHS 선수가 안정적인 로페즈 기술을 구사하기 위해서는 도마접촉 순간에 높은 자세로 진입하여 도마이륙 순간에서는 우측 견관절각을 크게하여 빠른 비틀기 각속도를 만들어야 한다. 최대높이와 착지 순간에서는 좌·우견관절각을 작게하여 관성모멘트를 줄이고 신체중심을 낮춰야 할 필요가 있다.

Objective : Balloon kyphoplasty can effectively relieve the symptomatic pain and correct the segmental deformity of osteoporotic vertebral compression fractures. While many articles have reported on the effectiveness of the procedure, there has not been any research on the factors affecting the deformity correction. Here, we evaluated both the relationship between postoperative pain relief and restoration of the vertebral height, and segmental kyphosis, as well as the various factors affecting segmental deformity correction after balloon kyphoplasty. Methods : Between January 2004 and December 2006, 137 patients (158 vertebral levels) underwent balloon kyphoplasty. We analyzed various factors such as the age and sex of the patient, preoperative compression ratio, kyphotic angle of compressed segment, injected PMMA volume, configuration of compression, preoperative bone mineral density (BMD) score, time interval between onset of symptom and the procedure, visual analogue scale (VAS) score for pain rating and surgery-related complications. Results : The mean postoperative VAS score improvement was $4.93{\pm}0.17$. The mean postoperative height restoration rate was $17.8{\pm}1.57%$ and the kyphotic angle reduction was $1.94{\pm}0.38^{\circ}$. However, there were no significant statistical correlations among VAS score improvement, height restoration rate, and kyphotic angle reduction. Among the various factors, the configuration of the compressed vertebral body (p=0.002) was related to the height restoration rate and the direction of the compression (p=0.006) was related with the kyphotic angle reduction. The preoperative compression ratio (p=0.023, p=0.006) and injected PMMA volume (p<0.001, p=0.035) affected both the height restoration and kyphotic angle reduction. Only the preoperative compression ratio was found to be as an independent affecting factor (95% CI : 1.064-5.068). Conclusion : The two major benefits of balloon kyphoplasty are immediate pain relief and local deformity correction, but segmental deformity correction achieved by balloon kyphoplasty does not result in additional pain relief. Among the factors that were shown to affect the segmental deformity correction, configuration of the compressed vertebral body, direction of the most compressed area, and preoperative compression ratio were not modifiable. However, careful preoperative consideration about the modifiable factor, the PMMA volume to inject, may contribute to the dynamic correction of the segmental deformity.

For this study, self-completion survey for 149 implant patients of dental clinics and hospitals in Seoul and Kyunggi areahas been executed in order to provide basic data for increasing patient satisfaction level by effective consultation and various information for the patients who want dental implantation. The conclusion of the study is like below. 1. In terms of demographics of the study, sample size of female patients(n=85) was more than that of male patients(n=64) and patients in their 50s were major age group. When it comes to the educational level, university graduates were 85 and high school graduates were 44. And 132 were married and 6 were single. In the income level, monthly income between KRW 2~4 million was major group(n=59). 2. In the study, patients' most concern was complication or adverse events(n=41), and price(n=39) & annual dental check-up(n=49) were following it. And 80 patients responded that dental health is the most valuable(n=80) and whole body health was following(n=37). In terms of knowledge on dental implant, 100 patients responded 'know just a little', 31 and 13 answered 'generally know' and 'well know' each. 3. As a result of analyzing implant patients' satisfaction level by segment, general satisfaction rate was highest as 4.20, social satisfaction rate was 4.20, psychological function was 4.06 and masticatory function was 3.90. 4. Based on the result of comparing patient satisfaction level by general characters of dental implant patient, chewing function was the highest in the age group of 60s with score of 4.21 and in terms of social function, the group with over KRW 8 million of monthly income showed highest score with 4.54. When it comes to the psychological function, patients in their 70s showed highest satisfaction level with 4.52. In the end, patients in their 70s showed highest score with 4.81 in the overall satisfaction and it was also statistically significant. 5. In the overall satisfaction level by interest in dental health, appearance showed highest score with 4.57 and it was also significantly higher than that of whole body. In the variance by dental knowledge, 'well know' group showed highest score with 4.58, and that of 'just a little' group was 4.33. That means there are correlations between dental knowledge and satisfaction level. 6. As a result of analyzing correlations amongst variances of the study, there were strong positive correlations among them. And there were very significantly positive correlations especially between social and psychological function and between psychological and overall satisfaction level. In conclusion, higher psychological function has strong relations with both social function and overall satisfaction level(p<.001).

It is well known that diabetes mellitus is associated with metabolic derangements, such as hyper-glycemia, ketosis, glycosuria, and also widespread alterations in the blood vessels, kidneys, eyes, peripheral nerves and heart. It is also recognized that healing of skin wound is delayed in diabetics. In bone, according to Aegerter, osteopenia develops in diabetes mellitus and it is chiefly ascribed to overutilization of protein. Shim claims that total blood flow to the entire skeletal system is approximately 4 to 8 percent of resting cardiac output and blood supply to the skeletal system would be decreased on account of secondary arteriosclerotic changes in the diabetics. An adequate blood supply is an essential factor in the healing process of fracture, and disturbed blood flow, either local or systemic, will invariably delay union of the fragments or the fragments from being fused. As the author has encountered several cases of diabetics in whom healing of fracture was delayed or incomplete, this experimental study was undertaken to elucidate the effects of hyperglycemia and diabetes mellitus on the healing process of fracture. In this experiment adult albino rabbits, weighing about 2 kg. were used and divided into 6 groups. The femur of each animal was fractured surgically, and then the healing process of fracture was periodically checked by radiography at an interval of one week for a period of 6 weeks. Thereafter, all the rabbits were killed to obtain tissue preparation of the femur. The experimental groups were as follows; 1) Control group: Six rabbits sustained a surgical fracture to the femur, without being given any other treatment or drug. 2) Alloxan-treated group: For inducing diabetes, alloxan was given intravenously to 17 rabbits in various dose as follows; to 7 of them 40 mg/kg, to 6 rabbits 80 mg/kg and to 4 rabbits 120 mg/kg of body weight, respectively. 3) Insulin-treated group: Protamine-zinc insulin was injected subcutaneously to each of 6 rabbits in a daily dose of 1 unit per kilogram of body weight. 4) Group treated with insulin after alloxan: Four rabbits were given 80 mg of alloxan once and than 1 unit of insulin per kilogram of body weight daily. Another 5 rabbits were injected 1 unit of insulin per kg of body weight daily following administration of alloxan in a dose of 120 mg/kg. 5) Homotransplantation group: Following intravenous injection of alloxan in a dose of 120 mg/kg, 10 rabbits underwent homotransplantation of a short bone segment to the femur. Five of them were subsequently given 1 unit/kg of insulin daily. 6) Sugar-treated group: six rabbits were fed $15{\sim}20$ gm of sugar daily throughout the period of experiment. The results obtained are summarized as follows; 1. Blood sugar level and damage to the pancreatic islet increased proportionately when alloxan was given to the rabbits in various doses. No appreciable change could be observed in the islets when the blood sugar level was altered by either oral administration of sugar or subcutaneous injection of insulin. 2. Comparing with the control group, healing of fracture was delayed in the alloxan-treated group, while callus formation and periosteal reaction were shown to be more prominent in this group and subsequently, the ultimate osseous tissue formed at the fracture site was significantly smaller in amount and less compact. These findings were more marked as the amount of alloxan increased. 3. Administration of insulin prevented the delay in healing process of fracture in the rabbits with alloxan-induced hyperglycemia. In this case, the course and progression of fracture healing were almost similar to those of control group. 4. Union between the host bone and the fragment transplanted from other rabbit of the same species was more delayed in the group treated with alloxan alone than in the group to which insulin was administered after development of alloxan-induced diabetes. In both groups periosteal new bone developed from the ends of the host bone, above and below the transplanted fragment, and directly fused with failure of periosteal callus to bridge the adjacent ends of the host bone and the transplanted fragment. 5. The healing process of fracture was not inhibited by alteration in blood sugar level when the blood sugar was abnormally increased by excessive sugar intake or lowered by administration of insulin alone. The healing of fracture in these groups progressed similarly as in the control group. In brief summary, it appears that the healing process of fracture would be definitely disturbed in diabetic state brought about by damage to the pancreatic islet. As such an inhibition could be overcome with insulin, it seems that insulin plays an important role in healing of fracture, but alteration in blood sugar level alone does not modify healing process of fracture to significant degree.
