Background: The objective of this article is to make some analysis on the process of work and accidents occurring in slaughterhouses, evidenced in the Brazilian documentary film called Flesh and Bone. As such, it was necessary to discuss an alternative theoretical concept in relation to theories about health and safety at work. This alternative discussion focuses on the concepts of biopower and biopolitics. Methods: The use of audiovisual elements in research is not new, and there is already a branch of studies with methodological and epistemological variations. The Brazilian documentary Flesh and Bone was the basis for the research. The analysis of this documentary will be carried out from two complementary perspectives: "textual analysis" and "discourse analysis." Results: Flesh and Bone presents problems related to health and safety at work in slaughterhouses because of the constant exposure of workers to knives, saws, and other sharp instruments in the workplace. The results show that in favor of higher production levels, increased overseas market sales, and stricter quality controls, some manufacturers resort to various practices that often result in serious injuries, disposal, and health damages to workers. Conclusion: Flesh and Bone, by itself, makes this explicit in the form of denunciation based on the situation of these workers. What it does not make clear is that, in the context of biopolitics, the actions aimed at solving these problems or even reducing the negative impacts for this group of workers, are not efficient enough to change such practices.

Polyphenols may be primarily responsible for the health benefits associated with tea consumption. However, the benefits of the tea polyphenols to bone health have not been studied well. The purpose of this study was to investigate the effects of Oolong tea on bone mineral density and bone-related markers in ovariectomized rats. Sprague-Dawley female rats were randomly assigned to Sham-Control, Sham-Oolongtea, Ovx-Control, and Ovx-Oolongtea groups. Bone mineral density (BMD) and bone mineral content (BMC) were estimated by using PIXImus (GE Lunar Co, Wisconsin.) in the spine and femur. After 6 weeks of the experimental diets, body weight gain, food intake, and food efficiency ratio (FER) were significantly higher in Ovx groups than in Sham groups regardless of diet. The serum concentration of calcium, phosphorus, ALP, and calcitonin were not significantly different according to Oolong tea supplementation. There were no significant differences in urinary calcium and phosphorus excretion between all groups. The urinary DPD crosslinks value was significantly higher in the Ovx-Control group than in the Sham-Oolongtea group. Spine BMD, femur BMD, and spine BMD per body weight were significantly lower in the Ovx groups than in the Sham groups regardless of diet. In the OVX group, spine BMC per body weight, femur BMD per body weight and femur BMC per body weight were significantly higher in the Oolong tea groups than in Control groups. It was concluded that Oolong tea supplementation positively influenced bone health in ovariectomized rats.

As dental implant surgery and bone grafts were widely operated in Korean dentist, many bone substitutes are commercially available, currently. For commercially used in Korea, all bone substitutes are firstly evaluated by the Ministry of Health and Welfare (MOHW) for safety and efficacy of the product. After being priced, classified, and registration by the Health Insurance Review and Assessment Service (HIRA), the post-application management is obligatory for the manufacturer (or representative importer) to receive a certificate of Good Manufacturing Practice by Ministry of Food and Drug Safety. Currently, bone substitutes are broadly classified into C group (bone union and fracture fixation), T group (human tissue), L group (general and dental material) and non-insurance material group in MOHW notification No. 2018-248. Among them, bone substitutes classified as dental materials (L7) are divided as xenograft and alloplastic bone graft. The purpose of this paper is to analyze alloplastic bone substitutes of 37 products in MOHW notification No. 2018-248 and to evaluate the reference level based on the ISI Web of Knowledge, PubMed, EMBASE (1980-2019), Cochrane Database, and Google Scholar using the criteria of registered or trademarked product name.

Vitamin K, which is a nutritional factor, play a role in the regulation of bone metabolism. Vitamin K exists naturally in 2 forms, namely, vitamin $K_1$ (phylloquinone) in green plants and vitamin $K_2$ (menaquinone) in animals and bacteria. Vitamin $K_1$ has an effect on bone metabolism. Vitamin $K_2$ is essential for the ${\gamma}$-carboxylation of osteocalcin, a bone matrix protein containing ${\gamma}$-carboxyglutamic acid (Gla) which is synthesized in osteoblast of bone tissues. This paper is to provide the basic information of vitamin K by supplying function and biological activity of vitamin K together with vitamin K producing lactic acid bacteria and it's utilization for the dairy products production.

This study was performed to be used as basic data to preventive the osteoporosis of a rural community people, after finding out the bone mineral density and a state of health, that of exercise, body composition and basic physical strength of the rural community adult. the subject for 143 adults of a rural community, the relation between bone mineral density and a state of health, that of exercise, body measurement and basic physical strength was studied. The research results were as follows. 1. In survey subjects, the more the age increased(p<0.01) and the lower the educational level was, the lower bone mineral density was(p<0.05). 2. Bone mineral density was significantly lower in those who had chronic diseases than those who didn't (p<0.05). 3. Bone mineral density was significantly higher in those who had much weight, BMI, body fat mass, and fat-free mass than those who didn't(p<0.01). 4. Bone mineral density was significantly high in those who exercised in the past, whose basal metabolism was high, and whose muscle mass was much(p<0.05). 5. Bone mineral density was high in those who had much grasping power and a number of sit-ups and push-ups (p<0.01). 6. As a result of Multiple Regression Analysis in which BMD was a dependent variable, the more the age increased, the more the score of bone density decreased when they had chronic diseases. And the exercise of the past affected the increase of bone mineral density.

Purpose: The study investigated the relationship of health behavior with bone mineral density (BMD) for college students. Methods: A descriptive study was done using a convenient sampling of college students (n=116) enrolled in a health-related department. Height, weight, body mass index (BMI), health behaviors recognition of subjective health, smoking, drinking, exercise, food habits, intake of calcium, and family history of fracture were measured. BMD was measured at the right forearm using Hologic lunar duel-energy X-ray absorptiometry. Data were analyzed using descriptive analysis, t-test, ANOVA and multiple linear regression. Results: The prevalence of osteopenia and osteoporosis was 41.4% and 22.4%, respectively. Significant relationships were observed between BMD of right forearm and gender, BMI, subjective health recognition, drinking, and exercise (p<.05). Results of linear regression after adjusted BMD were increased concerning subjective health recognition and regular exercise (p<.05). Conclusions: Subjective health recognition and exercise carries positive effects on BMD. We recommend for college students that healthy behaviors like proper weight, smoking cessation, regular exercise, regular food habits, and health awareness are helpful to BMD.

Purpose: This study was performed to assess the relationships among bone mineral density, dietary habits, life styles and anthropometric measurements in young women. Subjects included 229 female college students in Seoul and Kyunggi province. Method: The subjects were asked about dietary habits and life styles using questionnaire. A sampel of 229 young women was assessed anthropometric measurements and bone mineral density on calcaneous using quantitative ultrasound. Result: The percentages of the osteoporosis(T-score<-2.5), osteopenia(-2.5${\leq}$T-score<-1.0), and normal(T-score${\geq}$-1.0) groups were 1.75%, 13.53% and 84.71%, respectively. Weight, soft lean mass, and BMI were positively related with T-score and Z-score. But height was negative related with SOS(Speed of sounds). Conclusion: This study confirmed that one of the most effective ways to minimize bone mineral density less in young women is to maintain an adequate body weight, soft lean mass, and BMI. And the young women were recommended do not one-side eating, daily intakes of milk products, perform daily physical exercise, and do not drink coke or soft drinks for the bone health.

Osteoporosis is a disease that often occurs in postmenopausal women. The purpose of this study was to examine the positive effects of Cheongukjang powder containing menaquinone-7 (MK-7) on bone health circulation in postmenopausal women. Fifty-six postmenopausal women were recruited into a randomised double-blind placebo-controlled trial. The participants were randomly assigned into two groups. For 12 weeks, one group received $800{\mu}g$ MK-7 in the form of Cheongukjang packs (CMK-7), and the other group received the same amount of identical-looking placebo packs containing barley meal for 12 weeks. Femoral bone mineral density (BMD), bone-specific alkaline phosphatase (ALP), deoxypyridinoline (DPD), osteocalcin (OSC), serum Ca, and serum P were measured at baseline (0 weeks) and 12 weeks. After 12 weeks in the CMK-7 group, it was found that BMD, serum Ca, and serum P had increased above the baseline (p<0.0001, p=0.0028, p<0.0001), whereas bone-specific ALP, DPD, and OSC had decreased below the baseline (p=0.0003, p<0.0001, p<0.0001). Therefore, MK-7 taken as Cheongukjang is expected to prevent osteoporosis in postmenopausal women.

This study was designed to analyze the results of bone mineral density test in oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 3,206 industrial workers who had received oriental medical examination by oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by sex, age, job class, drinking history, smoking history and exercise history. The T-scores were measured by using OSTEOPRO(BMTECH, Seoul, Korea). We analyzed the relationship between sex, age, job class, drinking history, smoking history, exercise history and the results of bone mineral density using X2-test of the SPSS Ver. 14.0. There was a positive correlation between age and osteoporosis prevalence. In job class, sales personnel were apt to have a higher prevalence of osteoporosis than factory workers and office workers. Osteoporosis rates of the drinker group showed a higher level than the non-drinker group. Bone mineral densities of non-smoker group were higher than the Smoker group. And bone mineral densities of exerciser group were higher than the non-exerciser group. They have to encourage exercise and educate the workers to quit smoking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.
