감자를 포함한 오카(Oxalis tuberosa Molina), 오루코(Ullucus tuberosus Caldas), 이사뇨(Tropaeolum turosum Ruíz & Pav.)와 같은 볼리비아 전통 괴경작물들은 풍부한 영양성분을 함유하고 있으며 지역 농업 생물 다양성에 기여하고있다. 볼리비아는 오랜 기간 취약계층 굶주림 문제를 겪고 있으며최근 이상기후로 인한 전례 없는 유전적 침식의 위협을 받고있는 상황이다. 이 연구는 볼리비아 괴경식물들의 영양성분분석을 통해 식량안보 강화 및 기후변화에 능동적으로 대응하며 추후 볼리비아 감자 육종의 새로운 지표를 제시하고자 함이다. 연구는 감자를 포함한 총 21종의 볼리비아 괴경작물의 전반적인 영양성분검사를 연관성 및 변동성(correlation and variance)분석, 다변량분석(Multivariate analyses), Multitrait Genotype-Ideotype Distance Index (MGIDI)분석 통하여 주요미네랄 성분과 그 함량을 분석하였다. 분석 결과들은 볼리비아 괴경식물의 영양학적 가치를 높이고 볼리비아에 식량안보 관련 중요한 인사이트를 주며 추후볼리비아 감자 육종 분야에도 주요한 전략 지표를 제공할 것이다. Bolivian tuber species like potato (Solanum tuberosum), native potato (Solanum sp), Oca (Oxalis tuberosa Molina), Olluco (Ullucus tuberosus Caldas), and Isaño (Tropaeolum turosum Ruíz & Pav.) hold extraordinary nutritional value and cultural significance, particularly within the Andean region. This study examined the mineral composition of Bolivian tuber species as an essential step toward understanding their nutritional significance and potential contributions to addressing dietary deficiencies. The research involved detailed analysis of diverse tuber cultivars, uncovering distinct mineral profiles across species. Native potato shows high levels of nitrogen (N), potassium (K), phosphorus (P), and magnesium (Mg) levels, alongside moderate micronutrients like iron (Fe) and zinc (Zn). Commercial potatoes exhibited prominence in N, P, and K, with moderate Fe, Zn, and manganese (Mn) levels. Oca, Isaño, and Papa Lisa displayed unique mineral concentrations, offering potential nutritional benefits. Intricate correlations and significant variances among elements highlighted the diverse mineral compositions among these tuber species. Multivariate analyses emphasized distinct mineral profiles unique to each species, revealing significant compositions of isaño and papa lisa's. The Multitrait Genotype-Ideotype Distance Index (MGIDI) identified isaño jaspeado, isaño and an unnamed native potato, AXT2, as promising ideotypes due to their exceptional mineral compositions. These findings provide comprehensive insights into Bolivian tuber species' various mineral compositions, underscoring their nutritional significance and potential in targeted breeding for improved dietary support and enhanced food security.

This study examined the types of vitamin and mineral supplements sold for children in Korea and assessed the nutrient composition and the appropriateness of these products. A total of 343 vitamin and mineral supplements were identified using the search keyword “kids” on the homepage of the information portal managed by the Ministry of Food and Drug Safety. Data regarding the name, manufacturer, nutrient composition, nutrient content, and usage were obtained. Among the 343 products, 14.9% contained vitamins only, and 15.4% comprised minerals only. Thirty products (8.7% of total) were single vitamin compositions, and 48 were single mineral supplements. The most common nutrients to be found were vitamin C (70.0%) in single vitamin products, and calcium (50%) and zinc (50%) in single-mineral products. Vitamin D (64.9%) and vitamin C (56.2%) were the most frequently found, and zinc (58.9%) was the most prevalent mineral in the supplements that combined multivitamins and minerals. Although in more than 50% of the products, the suggested dosages were less than 150% of the Recommended Nutrient Intake (RNI) or the Adequate Intake for a daily dose, some of the products were found to be inappropriate for use. Amounts greater than the Tolerable Upper Intake Levels were found in 14 supplements containing zinc, 12 containing folic acid, and 9 containing magnesium. Further, 48 products consisted of vitamin C in amounts greater than 250% of RNI. The results of this investigation suggest, therefore, that parents should consult a trained dietician or should themselves have adequate knowledge about the nutrient composition of supplements and be capable of selecting the appropriate supplement for each child from the variety of vitamin and mineral products that are available at the counter

The aim of this research was to examine the correlation between body composition(weight, lean body mass, skeletal muscle mass, fat mass, BMI, %fat, WHR) and bone mineral density of combat sports athletes. Subject groups were divided into ssireum(n=10), wrestling(n=10), boxing(n=10) and taekwondo(n=10). For date analysis one-way ANOVA(LSD) and Pearson"s correlation coefficient were used. There were statistically significant differences on all variables of body composition. Weight, fat mass and %fat of ssireum group were higher than those of boxing and taekwondo groups. Lean body mass and skeletal muscle mass of ssireum were higher than those of wrestling, boxing and teakwondo groups. BMI of ssireum was higher than that of wrestling, boxing and teakwondo groups, and BMI of wrestling group was higher than boxing group. WHR of ssireum and wrestling groups were higher than that of boxing and taekwondo groups. However, T-score showed statistically no significant difference among four groups. All items of body composition were expected to significantly correlate with bone mineral density, but they showed no significant correlation in four groups. Bone mineral density of combat sports athletes were considered to be relevant to the exercise form and density, volume of exercise rather than body composition. Further studies on relation between bone mineral density and physical fitness, exercise program should be performed on various ages and lots of combat sports athletes.

Serra, A.B.,Serra, S.D.,Serra, F.B.,Domingo, I.J.,Cruz, L.C.,Fujihara, T. Asian Australasian Association of Animal Productio 1995 Animal Bioscience Vol.8 No.2

This study was conducted 1) to compare the nutrient content and mineral composition of the Philoppine indigenous sheep and goats diets when grazed in common pasture during rainy season, 2) to determine the influence of sampling methods on nutrient content and mineral composition of upland (UP) and lowland (LP) native pastures, and 3) to compare these two pasture types in terms of nutrient and mineral composition. Experiment 1 used sis esophageally fistulated animals, three each for sheep and goats. Weekly extrusa collection was done for a period of three months. Experiment 2 was conducted in UP and LP; these were sampled thrice by three methods, plucking, clipping and use of three esophageally fistulated sheep. Results of Experiment 1 indicated that the diets of sheep were greater in crude protein(CP; p < 0.01) and ether extract(EE; p < 0.05) but lower in crude fiber (CF) and acid detergent lignin (ADL; p < 0.05) than that of goat diets. All other nutrient fractions including mineral composition were not significantly different from each other. Significant findings of Experiment 2 were: CP content of UP was in the order fistulated > plucked > clipped (p < 0.05); CP content of LP was greater (p <0 .05) in fistulated and plucked samples; and ash content was greater (p < 0.05) in fistulated samples of both pastures. The CP of UP was different (p < 0.05) from each sampling method but the CP of LP and ADL of both pastures were greater (p < 0.05) in clipped samples. Most minerals either macro or microminerals were greater in fistulated samples of both pastures. Pooled data of the two pastures showed that LP had better nutrient characteristics and greater mineral composition. Based from this study, there were few differences between the diets of indigenous sheep and goats when grazed in common pasture. Also, sampling methods influenced the nutrient composition of indigenous sheep diets.

이광무(Lee, Kwang-Moo) 공주교육대학교 초등교육연구원 2019 敎育論叢 Vol.56 No.4

이 연구는 대학헬스수업이 신체구성, 골밀도와 자가건강평가에 미치는 영향을 알아보기 위해 수행되었다. 대학교 스포츠 교양강좌인 주1회 15주간‘헬스’수업을 수강한 31명의 대학생의 신체구성, 골밀도와 자가건강평가에 미치는 영향을 알아본 결과 다음과 같은 결론을 얻었다. 신체구성과 골밀도의 변화에서 유의한 변화가 없었으며, 자가건강평가 요소의 11가지 요소 중 음주, 흡연 기타 약물 사용관련 항목을 제외한 10가지의 요소에서 매우 유의한 변화를 가져왔다(p<.001). 특히, 대인관계 및 업무환경, 정신건강, 체력관리와 같은 대학교 1학년 학생들에게 필요한 요소들에서 매우 유의한 변화를 가져온 것으로 나타났다. 신체구성과 골밀도에 있어 유의한 변화가 없었다는 것은 1주일에 1회의 운동으로 체중, 체지방량, 체지방률과 같은 신체구성의 변화와 골밀도의 변화를 가져오기에는 운동시간이나 운동강도에 있어 부족한 것으로 생각된다. 운동의 횟수와 시간을 증가시켜 신체구성과 골밀도에 변화를 가져올 수 있는 운동프로그램을 실시해야 할 것이라고 생각된다. 나아가 교양 체육수업에 있어 운동 종목의 다양성과 체계적인 운동프로그램 지도를 통해 규칙적인 운동 습관과 건강한 대학생활을 할 수 있도록 하여야 할 것이다. The purpose of this study was to examine the positive effects of educational health education of university on body composition, bone mineral density and self-assessment of health. The subjects were 31 students at exercise health education classes per a week during 15 weeks. When body composition, bone mineral density and the self-assessment of health was to investigate the average of the items, we got conclusions as follows. The students in exercise health education classes(15 weeks) had not significantly difference in body composition. Second, the students in exercise health education classes had not significantly difference in bone mineral density. Third, the students in exercise health education classes had significantly difference in self-assessment of health in nutrition and weight control, disease prevention, sex and health, personal safety and violent accident prevention and consumer protection for health and healthy environment beside in drinking, smoking medicine using, and disease prevention. Overall results suggest that the exercise health education classes has not significant effects in body composition and bone mineral density. However there are changed significantly in self-assessment of health except in drinking, smoking medicine using, and disease prevention. So we need to provide systematic health education and exercise prescription to the student who to participate in physical education of the university.

최지연(Ji Yeon Choi),김종혁(Jong Hyuck Kim) 한국무용과학회 2009 한국무용과학회지 Vol.19 No.-

본 연구는 비만중년여성(신체질량지수 25이상) 30명을 대상으로 12주간 발레프로그램을 실시하여 신체구성 및 골밀도의 변화를 비교해 봄으로써 발레가 비만중년여성의 건강증진에 긍정적인 영향을 미칠 수 있는 운동형태인지 알아보고 변화상태를 분석한 결과 다음과 같은 결론을 얻었다. 첫째, 발레군에서 체중, 신체질량지구, 근육량 등에서 유의한 차이가 나타났다. 둘째, 발레군에서 요추 및 좌측대퇴골경의 골밀도 관련 변인들이 향상되었으나 통계적으로 유의한 차이가 나타나지 않았다. 이상의 결과를 토대로 12주간 발레프로그램의 규칙적 참여가 비만중년여성의 신체구성과 골밀도에 긍정적인 효과를 미치며 삶의 질을 개선하는데 의미가 있을 것으로 판단된다. 한편 추후 비만중년여성의 신체구성 및 골밀도 향상을 위한 장기간 다양한 운동 프로그램과 식이요법 등을 병행한 연구가 이루어져야 할 것으로 사료된다. The purpose of this study was to find out whether a ballet program could give positive effect to improve obese middle aged women's health by comparing the differences of body composition and bone mineral density after continuing 12 weeks ballet program. The results are as follow. First, with the differences in body composition, weight, BMI and muscle mass showed differences in ballet group, but any differences in control group. Second, with the differences in bone mineral density (BMD), lumber and BMD of left femoral neck, T-score and Z-score were increased but no statistical differences in ballet group. Also, there were no differences in control group. The results of body composition and bone mineral density through 12 weeks ballet program showed differences in only body composition. There were no difference in bone mineral density, but continuing this program can be considered as to improve the quality of life with positive effects in body composition and bone mineral density of obese elderly women. In the future, there will be needed further studies such as various long-term exercise programs and dietary treatment for obese elderly women.

성인여성의 골무기질상태와 신체구성과의 상관관계

이강구 한국웰니스학회 2012 한국웰니스학회지 Vol.7 No.3

골밀도는 주로 유전적요인, 성별, 연령, 약물, 흡연, 음주, 영양상태, 신체구성, 신체활동 등에 주로 영향을 받는다. 본 연구는 우리나라 성인 여성을 대상으로 골밀도와 신체구성간의 상관관계를 알아보고자 연구를 수행하였다. 연령은 20세에서 69세의 우리나라 성인여성 3519명을 대상으로 선정하였다. 골무기질 검사는 QDR-4500 장비를 이용하여 골밀도, 골질량, 골면적을 검사하였으며, 신체구성 검산는 Biospace-Inbody4.0. 장비를 이용하여, 신장, 체중, 신체질량지수, 복부지방률, 체지방률, 지방량, 제지방량을 검사하였다. SPSS 11.0 통계프로그램을 이용하여 모든 변수의 평균, 표준편차를 구하였다. One-Way ANOVA로 연령대간의 평균차를 비교하였으며, 사후검증은 Duncan법을 사용하였다. 단변량 회귀분석을 실시하여 회귀방정식을 구하였다. 본 연구의 결과는 다음과 같다. 골밀도는 신장, 체중, 신체질량지수, 제지방량과 정적인 상관관계를 나타났으며, 연령, 복부지방률, 체지방률과는 부적인 상관관계를 나타났다. 골밀도와 신체구성 변수에 대한 단순회귀분석 결과는 다음과 같다. 연령은 11.9%(R2=0.119), 신장은 7.6% (R2=0.076), 체중은 5.0%(R2=0.05)의 설명력을 나타내고 있으며, BMI는 0.6% (R2=0.006), WHR은 3.5% (R2=0.035), 체지방률은 0.4(R2=0.004)의 설명력을 나타내고 있다. 또한 체지방량은 0.5%(R2=0.005), 제지방량은 10.6% (R2=0.106)의 설명력을 나타내었다. 따라서 제지방량이 높은 여성에게서 골밀도가 높게 나타났으며, 골밀도가 낮은 여성은 체지방률, 복부지방률이 높게 나타났다. 골밀도가 낮은 여성은 제지방량의 감소로 근력이 낮아 근골격계 질환의 가능성이 높아질 뿐만 아니라 WHR의 지방량이 증가되어 비만과 관련된 질환의 위험도 높아질 것으로 사료된다. The bone mineral density(BMD) is influenced mainly by genetic factors, gender, age, drug, smoking, drinking, nutritional status, composition, physical activity. The major components of body composition, lean mass and fat mass, each of which is a potentially modifiable factor, may influence BMD more than total body weight alone. The muscle strength is also regarded as predictive factor to the BMD and bone fracture. The purpose of this research was to investigate the correlation between bone mineral status and body composition. The subjects consists of 3519 age of 20-69. Body compositions were measured using a Biospace-Inbody4.0. Body composition variables were age, height, weight, body mass index(BMI), waist-hip ratio(WHR), % body fat(%fat), fat mass(FM), fat free mass(FFM). BMD measurements were done by dual-energy X-ray absorptiometry(DEXA) using a QDR-4500 densitometer at the lumber spine(L1-L4). Experimental data were analysed through SPSS windows 11.0 PC+, and analysed by using multiple correlation, multiple regression and analysis of variance(ANOVA). The experimental results from this study are the following. BMD was positively correlated with height(r=0.275, p=0.000), weight(r=0.223, p=0.000), BMI(r=0.075, p=0.000) and FFM(r=0.325, p=0.000). However, was negatively correlated with age(r=-0.345, p=0.000), WHR(r=-0.186, p=0.000), %fat(r=-0.063, p=0.000). Stepwise linear regression analysis showed that height, weight, FFM, age and WHR were associated with BMD. BMD was higher in women with high FFM. BMD was lower in women with high WHR and %fat.

Kim Eui sik,Park Ju sik J-INSTITUTE 2018 International Journal of Martial Arts Vol.3 No.1

This study investigated the effects on body composition, physical fitness, and bone mineral density (BMD) of 20 elderly women aged 60 or older residing in G city, K province who participated in the Dahn-taekwondo Qigong program for the elderly for 1 hour per day, 3 times a week for 3 months. This study examined the suitability of incorporating elderly Qigong program into the exercise prescription program for the elderly with decreased phys-ical activity ability. The results showed that the Dahn-taekwondo Qigong program showed a significant decrease only in body fat percentage among the elderly women’s body composition. For the fitness factor, all the fitness factors except cardiopulmonary endurance for the normal weight group and agility and dynamic equilibrium measures for the overweight group were significantly improved. Also, it showed a significant increase in the BMD of the normal weight group. Based on the observations mentioned above, participating in Qigong program for the elderly will be suitable as a health promotion program for the elderly by improving BMD and fitness factors even though the body composition does not change so much.

박선영 ( Park Sun Young ),이경북 ( Lee Kyungbook ),최지영 ( Choi Jiyoung ),박주영 ( Park Ju Young ) 한국광물학회 2024 광물과 암석 (J.Miner.Soc.Korea) Vol.37 No.2

퇴적물 내에서 가스 하이드레이트(gas hydrate, GH) 부존 가능성을 파악하기 위해서는 획득된 코어 시료의 광물 조성을 아는 것이 필수적이다. GH 탐사를 진행하며 채취된 울릉분지 코어 시료에서 각 시료 별 488개의 X선 회절 분석(X-ray diffraction, XRD)을 활용하여 광물 조성 값을 확보하였다. 488개의 학습 자료를 기반으로 입력값을 3100개의 XRD 피크 세기로 출력값을 12개의 광물 조성으로 기계학습을 수행하였다. 488개의 데이터를 307개의 학습자료, 132개의 검증자료, 49개의 테스트 자료로 나누어 학습을 수행하였고 랜덤 포레스트(random forest, RF) 알고리즘을 활용하여 결과를 획득하였다. 학습 결과 전문가가 예측한 광물 조성과 기계학습을 통해 예측한 값의 차이인 평균 절대 오차(mean absolute error, MAE)가 1.35%로 확인되었다. 개발된 모델 성능의 개선을 위해 주성분분석(principal component analysis, PCA)을 활용하여 XRD 피크의 핵심 특징을 추출하여 입력자료의 차원을 줄여 추가적으로 기계학습을 수행한 결과 MAE 값이 최대 1.23%까지 감소하는 것을 볼 수 있었고 시간적인 측면에서 학습 효율도 향상된 것을 확인할 수 있었다. It is essential to know the mineral composition of core samples to assess the possibility of gas hydrate (GH) in sediments. During the exploration of gas hydrates (GH), mineral composition values were obtained from each core sample collected in the Ulleung Basin using X-ray diffraction (XRD). Based on this data, machine learning was performed with 3100 input values representing XRD peak intensities and 12 output values representing mineral compositions. The 488 data points were divided into 307 training samples, 132 validation samples, and 49 test samples. The random forest (RF) algorithm was utilized to obtain results. The machine learning results, compared with expert-predicted mineral compositions, revealed a Mean Absolute Error (MAE) of 1.35%. To enhance the performance of the developed model, principal component analysis (PCA) was employed to extract the key features of XRD peaks, reducing the dimensionality of input data. Subsequent machine learning with the refined data resulted in a decreased MAE, reaching a maximum of 1.23%. Additionally, the efficiency of the learning process improved over time, as confirmed from a temporal perspective.
