The purpose of this study was to investigate the life style, self-efficacy, and Bone Marrow Density (BMD) in osteoporosis female patients. The subjects were recruited at the four Osteoporosis Clinics. A convenience sample of 190 women completed a survey instrument which included the Osteoporosis Self-Efficacy Questionnaire, Life Style Questionnaire and demographic items. BMD of L$_4$ was measured by Dual Photon Absor photiometry. The sample ranged in age from 40 to 82 years (Mean＝60.28). Eighty-one percent were married and 14.9% were widowed. Forty-four percent lived with their spouse and children. Excercise, diet, medication, alcohol consumption, and smoking were measured to investigate the life style. Fifty-seven percent of the subjects exercised regularly. Mountain climbing, brisk walking, and free gymnastics were frequently cited excercises by the subjects in this study. Sixty percent drank one cup of milk and 34.7% had 1.13 cups of coffee in a day. Thirty-nine percent used calcium supplements, 9.5% drank alcohol, and 3.2% smoked cigarettes. Economic status and education level were related to self-efficacy. Age, economic status, and education level were related to BMD. As a life style, exercise, diet(milk, ice cream, and coffee), and medication(calcium) were associated with self-efficacy. The subjects who exercised regularly and took calcium supplements for a longer time had a higher level of self-efficacy than those who did not. Smoking and alcohol consumption had no relationship with self-efficacy. Excercise, medication(calcium), and alcohol consumption were related to BMD. The subjects who took calcium supplements for a longer time had a higher level of BMD. Alcohol consumption was not related to self-efficacy but related to BMD. The subject who drank alcohol had a higher level of BMD than those who did not drink. The amount of alcohol consumption was positively related to BMD.

Purpose: This study investigated bone mineral density and nutritional state according to consumption of milk in Korean postmenopausal women who drink coffee. Methods: Using the 2008~2009 Korean National Health & Nutrition Examination Survey data, a total of 1,373 postmenopausal females aged 50 yrs and over were analyzed after excluding those with diseases related to bone health. According to coffee and/or milk consumption, subjects were divided into four groups: coffee only, both coffee & milk, milk only, and none of the above. All data were processed after application of weighted values and adjustment of age, body mass index, physical activity, drinking, and smoking using a general linear model. For analysis of nutrient intake and bone density, data were additionally adjusted by total energy and calcium intake. Results: The coffee & milk group had more subjects younger than 65 yrs and higher education, urban residents, and higher income than any other group. The coffee only group showed somewhat similar characteristics as the none of the above group, which showed the highest percentage of subjects older than 65 and in a lower education and socio-economic state. Body weight, height, body mass index, and lean mass were the highest in coffee & milk group and lowest in the none of the above group. On the other hand, the milk only group showed the lowest values for body mass index and waist circumference, whereas percent body fat did not show any difference among the groups. The coffee and milk group showed the highest bone mineral density in the total femur and lumbar spine as well as the highest nutritional state and most food group intakes, followed by the milk only group, coffee only group, and none of the above group. In the assessment of osteoporosis based on T-score of bone mineral density, although not significant, the coffee and milk group and milk only group, which showed a better nutritional state, included more subjects with a normal bone density, whereas the none of the above group included more subjects with osteoporosis than any other group. Conclusion: Bone mineral density in postmenopausal women might not be affected by coffee drinking if their diets are accompanied by balanced food and nutrient intake including milk.

As awareness of environmental issues continues to grow, there is an escalating demand for recycling and repurposing byproducts of agricultural and food production processes and their conversion to high-value products. Coffee is the most widely consumed beverage globally; during coffee beverage processing and consumption, byproducts such as coffee silverskin (CS), spent coffee grounds (SCGs), and oil are generated. Despite containing beneficial materials such as cellulose, hemicellulose, lignin, lipids, and bioactive substances, these byproducts are typically discarded in landfills or incinerated. The utilization of CS, SCGs, and oil in the development of packaging materials holds significant potentials toward the realization of a sustainable society. To this end, considerable research efforts have been dedicated to the development of high-value materials derived from coffee byproducts, including functional fillers, polymer composites, and biodegradable polymers. Notably, CS and SCGs have been employed as functional fillers in polymer composites. Additionally, lipids extracted from SCGs have been used as plasticizers for polymers and cultured with microorganisms to produce biodegradable polymers. This review focuses on the research and development of polymer/CS and polymer/SCG composites as well as cellulose extraction and utilization from CS and SCGs and its applications, oil extraction from SCGs, and cultivation with microorganisms using extracted oil for polyhydroxyalkanoates(PHA) production.

The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

This study tried to analyze the growth background of Starbucks, a competitive company in the Korean coffee industry. Therefore, by using the STEEP analysis technique, each company's competitiveness was analyzed and the results were used to derive competitive factors. And the research results are as follows. Looking at the social aspect, economic activity has been a catalyst for women as the standard of living has increased due to economic growth. In addition, in the case of coffee culture in the past, Starbucks' response strategy, which has seen the transformation from vending machine mixed coffee culture to a consumer market that emphasizes cultural and spatial aspects, was effective. Looking at the technical aspect, the deviation has been reduced by securing uniform standardization of the taste of coffee beans at franchise stores, and the operation of a standardized operating system was possible by operating the store directly. And looking at the economic aspect, as the coffee consumption market continues to expand, the overall size of the market has also grown proportionally, creating a stable growth environment. Lastly, looking at the environmental and policy aspects, it is that the marketing strategy direction based on the policy activities as an eco-friendly company as a market leader has been the main focus of the recent policy direction emphasizing eco-friendliness.

The purpose of this study is to analyze the foods which 424(male 171, female 253) university students surveyed consumed frequently and to evaluate and the factors affecting their food consumption patterns. The survey was conducted at the beginning of nutrition courses each semester, March and September, 1998, with the questionnaire composed of general information, food, drinking and smoking habits, nutrition knowledge/attitude and food frequency questionnaire. The rates of alcohol drinking in male and female students were 89.2% and 78.1% respectively, and the rates of smoking were 68.1% and 1.6% in males and female. The nutrition knowledge score was higher in females than in males, but the nutrition attitude score was not significantly different between the male and female groups. The foods frequently consumed among students were cooked rice(14.3/week), kimchi(11.1/week), coffee(5.7/week), vegetables in soup, jjigae and jorim(3.5/week), carbonated beverages(3.3/week), cooked mixed rice(3.2/week). Ramyun and chocolate·candies·biscuits were frequently consumed, too. There were several factors influencing food consumption patterns. These were gender, regularity of mealtimes, the status of alcohol drinking and smoking, residence type and the levels of nutrition knowledge and attitude. Males ate more frequently cooked rice, coffee, carbonated beverages, ramyun, functional beverages and ham·sausage, while females ate more frequently cooked mixed rice and fruits. Those who had the habits of irregular mealtimes seemed to eat more soft drinks, instant foods and snacks. These trends were also found in the alcohol drinking and smoking groups. High level groups for nutrition knowledge of attitude score chose raw yellow green and green vegetables, cooked mixed rice, soybeans and seaweeds more frequently than the other groups. On the other hand, low level groups for nutrition knowledge or attitude score were apt to eat carbonated beverages and ramyun more frequently. Therefore, more attention should be taken to males, having habits of irregular mealtimes, alcohol drinking and smoking, and low level groups for nutrition knowledge or attitude score so as to improve their health.

Purpose: This study analyzed the dietary patterns of Central Asian immigrant workers (Mongolia, Kazakhstan, Uzbekistan, and Kyrgyzstan) living in South Korea to determine the food acculturation and how their dietary practices have changed after immigration. Methods: Self-administered questionnaires were completed by 186 Central Asian immigrant workers living in South Korea. A food frequency questionnaire (FFQ) was used to obtain information on the consumption frequency of 22 food items before and after their immigration to Korea. Results: Central Asians switched to Korean meat consumption patterns, which consume mainly pork, chicken, and beef, showing a decrease in the intake of beef and lamb and an increase in that of pork. Their consumption of Namul (cooked vegetable), Kimchi, rice, and marine products increased while that of potatoes decreased during acculturation to Korean food culture. Positive changes were observed in Mongolians' eating habits. Their meat-based diet turned into a healthy one in which nutritional balance was achieved by consuming the various food groups. Negative dietary changes were also observed; intake of instant foods and coffee increased while black and green tea consumption decreased. Intake of Namul (p < 0.01), Kimchi (p < 0.01), rice (p < 0.001), ramen (p < 0.001), pork, chicken (p < 0.01), fish (p < 0.01), seafood (p < 0.001), and coffee (p < 0.001) increased significantly in the group that responded and their health improved after moving to Korea. This result suggests that health improved among those who were well settled in Korea and ate the various food groups. Conclusion: These findings can help understand the acculturation process to Korean food culture and provide a basis for developing policies to help them adjust to Korean food culture.
