DEXA, as the standard areal bone mineral density (aBMD) measurement method, often shows an insuficient correlation between aBMDs of the measured bones and referring bones and is inaccurate due to the mass effect. In contrast, quantitative computer tomography (QCT), as a volumetric BMD (vBMD) measurement method, is being advanced so that it uses less radiation before, owing to improved CT device and computer imaging technology. Because dual-energy CTs can modulate the image signals showing tumor or specific chemicals as well as the ability to measure vBMD, they are expanding their application. For pre-checking vBMD of surgeon-specific bone volume at implantation candidate sites, a finite element creation-based local vBMD measurement technique was developed. The local vBMD measurement function for surgeon-specific shape volumes will be added to clinical imaging systems.

본 연구는 폐경전 성인여성들의 골격상태를 알아보고 신체계측 및 식이섭취실태가 골밀도에 미치는 영향을 평가하기 위해서 성인여성 61명을 대상으로 신체계측을 실시하고 24시간 회상법으로 영양소 및 주요 식품군의 식품섭취실태를 조사하고 DEXA를 사용하여 요추와 대퇴부 3부위의 골밀도를 측정하였다. 1) 대상자들의 평균 연령은 37세였으며, 평균 신장과 체중은 158.17cm, 54.55kg였으며, 평균 BMI와 WHR은 21.82, 0.78로 대상자들의 비만도는 정상이었다. 2) 평균 골밀도는 요추(L24) 1.04 g/$\textrm{cm}^2$, 대퇴경부 0.76g/$\textrm{cm}^2$, 대퇴전자부 0.66g/$\textrm{cm}^2$, 와드삼각부 0.69g/$\textrm{cm}^2$이었다. 3) T-score로 판정시 요추(L24)의 경우 골다공증군 3.28%, 골감소증군 14.75%, 대퇴경부의 경우 골다공증군 9.84%, 골감소증군 52.46%, 대퇴전자부의 경우 골다공증군 1.64%, 골감소증군 34.43%, 와드삼각부의 경우 골다공증군 6.56%, 골감소증군 45.90%였다. 4) 영양소중 칼슘(78.75%), 철분(69.75%) 및 비타민 A(92.17%) 영양소의 1일 평균 섭취량은 영양권장량보다 낮은 수준이었다. 5) 신체계측 및 영양소섭취량과 골밀도와의 상관관계분석에서 신체계측에서 체중(p < 0.05), 엉덩이둘레(p < 0.01), 제지방함량(p < 0.05), 총수분함량(p < 0.05)이 높을수록 요추골밀도가 유의하게 높았으나, 영양소섭취량은 골밀도와 유의한 상관성을 보이지 않았다. 6) 주요 식품군의 식품섭취실태와 골밀도와의 상관관계분석에서 버섯군의 식품섭취횟수(p < 0.05, p < 0.05)가 많을수록 요추(L3, L24)의 골밀도가 각각 유의하게 높았으며, 유지류군의 섭취식품수(p < 0.05)가 많을수록 와드삼각부의 골밀도가 유의하게 높았으나 곡류군의 섭취식품수(P < 0.01, p < 0.05, p < 0.05)가 많을수록 대퇴부 3부위 (대퇴경부, 대퇴전자부 및 와드삼각부)의 골밀도가 각각 유의하게 낮은 것으로 나타났다. 이상의 결과에서 폐경전 성인여성의 경우 요추보다는 대퇴부 3부위의 경우 골다공증이나 골감소증의 비율이 상대적으로 높았으며, 특히 대퇴경부에 있어서 골다공증이나 골감소증의 비율이 가장 높았음을 알 수 있다. 또한 요추와 대퇴부 3부위의 골밀도는 영양소섭취량과 유의한 상관관계를 보이지 않았으나 체중, 엉덩이둘레 등의 신체계측요인과 곡류군, 버섯군 및 유지류군 등의 주요 식품군의 식품섭취실태와 밀접한 상관관계를 보이고 있음을 알 수 있다. 따라서 성인여성에 있어서 골밀도손실을 예방하기 위해 평상시 적절한 체중유지와 아울러 식생활지침에 있어서 주요식품군별로 적절한 섭취식품의 수, 섭취량 및 섭취빈도에 대한 영양교육이 필요한 것으로 생각된다.

We measured the body composition, including bone mineral density (BMD) and food resource availability using dual energy X-ray absorptiometry and the carbon and nitrogen stable isotope ratios of body condition of 4 anuran species(Hyla japonica, Glandirana rugosa, Pelophylax nigromaculatus, Lithobates catesbeianus) in South Korea. Additionally, the carbon and nitrogen stable isotope ratios were employed to determine the food resource availability of anurans. We figured out the relationship between the body composition, including BMDs and food resource availability. The body composition and BMDs did not differ between male and female while there was difference among the species. Food resource availability and BMDs were the highest in L. catesbeianus, the lowest in H. japonica. BMDs tended to increase with higher food resource availability. Body composition and BMDs, which represent the body condition of an individual, can be used as an ecological indicator to assess the stability of the habitat of anurans.

This study sought to reduce the risk of fractures in elite youth taekwondo athletes to find out the relationship between bone mineral density which are used as indicators of early diagnosis of osteoporosis and cardiorespiratory functional capacity which is an indicator of performance and sports injury the harmful to athletes. The Pearson product-moment correlation was performed to investigate the correlation between bone mineral density, cardiorespiratory functional capacity, and sports injury. The bone mineral density and cardiorespiratory functional capacity, sports injury were examined the relationship using the Simple Linear Regression. The bone mineral density were correlated with the ventilation (r=.388), and VO2max (r=.478). Bone mineral density was correlated with sports injury (r=-.292). When the bone mineral density increased by .002 and .006, the ventilation (p=.001) and VO2max (p=.006) increased by about 1. In addition, when the bone mineral density decline by .016, the sports injury increased by about 1. Improving athletes' bone mineral density can prevent sports injury, and it can be used as a sports injury prevention program in the future.

목적 : 본 연구는 척수손상환자들 중 신체활동 정도가 급격하게 차이 나는 운동 선수군과 비선수군의 일상생활동작과 골밀도를 비교 분석하는데 그 목적이 있다. 방법 : 본 연구를 위해 20명(선수 10명, 비선수 10명)의 SCI 환자가 실험에 참가하였다. 골밀도 측정을 위해 이중에너지 방사선골밀도 측정기(Lunar Prodigy, GE Healthcare. England)를 이용하여 종골부위(calcaneus)의 골밀도를 측정하였다. 척수손상환자의 일상 생활 기능을 측정하기 위해 자조관리(self care), 호흡과 괄약근 조절 (respiration and sphincter management task), 이동(transfer)의 세 영역으로 나누어진 SCIM II(Spinal Cord Injury Measurement II)을 이용하였다. 척수손상환자들 중 운동 선수군과 비운동 선수군의 일상생활 동작과 골밀도를 비교 하기 위해 SPSS 14.0 통계 프로그램의 independent t-test를 이용하여 통계분석을 실시하였고 일상생활 동작과 골밀도의 상관관계는 Pearson correlation을 실시하였다. 유의수준은 ${\alpha}$=.05로 통계처리 하였다. 결과 : 검사 결과 선수군이 비선수군보다 통계적으로 유의하게 큰 SCIM 점수와 T-score를 보여주었다. 결론 : 일상생활동작을 측정하기 위하여 SCIM II(SpinalCordIndependenceMeasureII) 척도를 사용하였는데 선수군이 비선수군에 비해 유의하게 높은 SCIM II 총점을 나타내어 운동을 통한 훈련이 척수손상환자의 기능적 활동을 향상시킬 수 있다고 사료된다. 그리고 골밀도 측정 결과 선수군이 비선수군에 비해 통계적으로 유의하게 높은 골밀도를 나타내었다. 이 역시 강도 높은 훈련이 척수손상환자에게 나타날 수 있는 신체구성을 강화시켜줄 수 있을 것으로 사료된다. 운동을 통한 재활 중에서 그 강도가 높을수록 신체의 구성적, 기능적 측면 뿐 아니라 신경의 가소성 측면에서도 증가를 기대해 볼 수 있을 것으로 판단된다.

We studied the relationship between prediction parameters and bone mineral density for pre-and-post menopausal women. We measured BMI%Fat by BIA, blood pressure and lipid profiles for 483 adult women who are in NPO state. SBP, TC, TG, LDL have significant statistical value in the postmenopause women group and postmenopause woman. The value of postmenopause women of these parameters are lower than premenopause woman. BMD has the most strongest relationship with LBM. The BMD and LDL level of postmenopause women have statistically negative relationship. The results show that for the premenopause cases, weight, BF, and HDL level were the major factors which affect the BMD. For postmenopause cases, however, weight, age, and LDL level turned out to be the most significant factors.

Purpose: To evaluate the correlation between BMD and life habit such as drinking. exercise smoking or physical condition such as age, sex, height, weight, body mass index(BMI). Materials and Methods: I evaluated the BMD of the femoral neck and L2-L4 spines of 321 persons who took a regular health screening in Woosuk university oriental medical hospital from February to April in 2006 by dual energy bone mineral densitometry. Results: The age of persons ranged from 20 years to 75 years(mean $45.10{\pm}11.54$) and there were 160 males and 161 females. In males, BMD of the femoral head was highest at 2nd decade, BMD of the spine was highest at 4th decade, and BMD of both femoral head and lumbar spine was lowest at 6th decade. In fenales, BMD of both femoral head and lumbar spine was highest at 4th decade and lowest at 6th decade. Among the various physical conditions, only height of persons showed significant correlation with BMD in both males and females. BMD was increased according to increasing height. In males, BMD of persons who had habit such as drinking, exercise or smoking did not show significant change statistically. But in females, drinking group showed high BMD relative to non-drinking group in both femoral head and lumbar spine. Conclusion: BMD was different according to age, sex, height and life habit. Especially aged people showed osteoporotic change progressively. More persistent effort is needed to find out the factors decreasing BMD for prevention of problems by osteoporosis.

The bone mineral density built in adolescence and college term is formed to the highest level between 25 years old and 35 years old and the formed bone mineral density is decreasing in the middle years and senescence. Decrease of the bone mineral density causes Osteopenia and an increase of dangerousness of a bone fracture which become social health problems. This research is to give guidance for the right living style by surveying the relation between the bone mineral density and college students' life. The result is like below. First of all, most objects of the research were insufficient of quantity of motion and the diet they have was consisted of instant food. It was far from the right living habit and exercise and the bone mineral density was also low. Second of all, male students showed more osteopenia than female students in this research and the smokers' bone mineral density was lower than nonsmokers, which proved that smoking in adolescence was related to the bone mineral density. Finally, the opportunistic eating and living style and the excessive diet and unequal caloric intake caused by the notion of preference for a slim person are considered to be the main reasons for the decrease of the bone mineral density.

The purpose of this study was to investigate the relation between NEAP (net rate of endogenous noncarbonic acid production) from dietary potassium and protein intakes, and bone mineral density and urinary deoxypyridinoline (DPD) in Korean women. The subjects were 276 women aged $18\sim81$, and they were asked about general characteristics and nutrient intake using 24-hr recall method. Also, their bone mineral density of spine and femoral neck were measured using DEXA. Urinary DPD analysis was done in 106 postmenopausal women. The average energy, protein and potassium intake were 1503.0 kcal, 57.7 g and 60.8 mEq, respectively. Mean NEAP [54.5$\times${protein intake (g)/potassium intake (mEq)}-10.2] was 44.6. NEAP showed a significantly negative correlation with spine bone mineral density of the subjects after controlling for confounding factors (age, height and weight) (p<0.05). The lowest quartile of protein intake had the highest spine bone mineral density after controlling for confounding factors (p<0.05). There was no significant correlation between urinary DPD and calculated NEAP. These results provided positive relation between a ratio of lower protein to higher potassium dietary intake and bone mineral density.
