  • As a result of life-style changes, consumer's concerns of food have shifted from calories and nutrition to health and convenience. Fresh-cut products are one such new direction for fruit and vegetable consumption. In this study, the vitamin C, mineral, and pesticide contents of various fresh-cut products were analyzed. According to sensory evaluations, the key reason for a lower than expected overall acceptability of many fresh-cut products is that they are likely to have browning and can easily lose their freshness. Also, the sensory evaluation showed that shriveling, the degree of browning, softening around the cut edge, and off-flavors were the primary factors affecting the quality of fresh-cut products. As a nutritional factor of quality, vitamin C content was not practical with regard to fresh-cut lettuce because the level was very low. For product safety, residual pesticides were detected in the fresh-cut products, but the results showed that all items were under permitted levels and considered safe. In evaluation of the microbial levels of the fresh-cut market products, the levels of viable cells, mold, yeast, coliform bacteria, and enterobacteriaceae were not significantly different based on the summer and winter seasons. The levels of S. aureus and Listeria spp. in the products were higher during the summer season than the winter.

  • The purpose of this study is to form a calculation formula of the mean skin temperature on the human body in a heated room by the use of floor heating system. Korean traditional floor heating system is a long way from being defunct. The floor heating systems based on hot water have been coming into wide use mainly in the apartment house. However, it is considered that the design process and evaluation method for the floor heating systems in the standpoint of human being are not established so far. In the floor heating systems, air temperature as well as floor temperature should be considered as physical factors which affect the sensation of human body. Furthermore, extremely few studies have been performed on the sitting with legs crossed posture sedentary which is the typical dwelling life style of residents from the ancient times in Korea, while a large number of studies on the influence of the floor heating systems on the human body in standing and sitting on a chair sedentary have been carried out. Especially, it is essential to elucidate how mean skin temperature on the human body is affected by thermal conduction in the contact area between the sitting with legs crossed posture sedentary human body and floor including thermal radiation due to the combination of air temperature and floor temperature, but the studies dealt with such issues have hardly been performed. Based on the above statements, the influence of the environment condition due to the combination of air temperature and floor temperature is discussed in the present investigation through theoretical of mean skin temperature on the human body in the floor heating systems.

  • Underreporting of dietary intake is common and might distort analysis and interpretation of dietary surveys. This study was designed to investigate the degree of underreporting and characterastics of under-reporting group in Korean college female students. Dietary survey of 1-day 24-hour recall method was conducted on 379 college students in Seoul and Chonan areas. Physical activity and life style were aquired from questionnnaires. Underreporting was defined as energy intake(EI) lower than 0.9BMR(based metabolic rate), since EI<0.98BMR is statistically judged as bias in 1-day 24 hour recall. BMR was calculated from Schofield's equation. Proportion of underreporting was 18.7% and it's not so different from one of American or European women. Intake of nutrients except vitamin A by underreporting group was lower than other groups(p<0.001). Proportions of subjects with nutrient intake level less than 75% of Korean RDA were more than 80% in protein, Ca, Fe, vitamin A, riboflavin, niacin, zinc as well as energy. Dietary quality of underreporting group was also worse than other groups. Proportion of subjects less than 3 food groups among 5 food group was higher in underreporting group. The number of foods eaten by underreporting group were also less than those of other groups. BMI and body weight were the largest in underreporting group(p<0.05) and the trial of weight reduction was shown higher trend(p<0.01). Different in PAC and other characteristics between underreporting group and other group were not significant. Not only dietary quantity but also dietary quality were worse in the underreporting group. Furthermore underreporting in college female students seemed to be affected by body weight and concern for weight reduction.

  • The purpose of this study is to investigate the relationship between menopausal symptoms and spiritual well-being. In order to collect the research data, 350 questionaries were sent to the middle aged women who were 40-59 years old. During the collection period, March 20, 1977-April 20, 1977, 264 questionaries were collected. The questionnaire was prepared by using other researchers' scale, such as menopausal symptom scale by Neugarton and spiritual well-being scale by Paloutzian & Ellison. The research data were analyzed by various testable methods, such as frequency, t-test or ANOVA, and Pearson's correlation. The main results of this study were as follows ; Among the general characteristic variables, some variables have statistical significancy in explaining the difference of the menopausal symptoms. Such variables include age(F=5.17, p=0.002), years get married(F=4.23, p=0.002), number of children(F=3.08, p=0.028), income level of family(F=3.07, p=0.017), life style at leisure time(F=2.47, p=0.045). Some variables related to health condition could explain the differences of the menopausal symptoms among middle aged women. current menstruation stage(F=9.82, p=0.000), current health condition(F=9.82, p=0.000), and experience being operated in the past(F=9.82, p=0.000) are related to the menopausal symptoms. Serious menopausal symptoms which could be found in this study were 'back pain and joint pains(2.6)', nervousness(2.4), and psychosomatic symptom(1.97). Spiritual well-being inquiries could be classified into two subgroups, existential and religious. The mean score of existential well-being(3.04) was higher than that of religious well-being(2.76). Relatively higher existential well-being(3.10) was found in the women who have stable menstruation cycle. The age when the menopause began was related to spiritual well-being(F=3.29, p=0.046). The correlation between menopausal symptoms and spiritual well-being was statistically significant(r=-0.133, p=0.031). Based on the above results, nursing intervention program of menopausal symptoms is recommended in order to promote the health of middle-aged women.

  • Objective: Human milk bank is known as best alternative option for sick infants. However, only two human milk banks (HMBs) are working in Korea. In the present study, we evaluated the awareness on the HMB in female health care provider to find out the issues that would help facilitating HMB establishment in Korea. Methods: The survey questionnaire was developed by a team composed with neonatologists, obstetricians, nurses, nutritionists, and health care specialists. The survey was performed for female health care workers in Soon Chun Hyang Cheonan Hospital between March and June in 2016. Eighty-eight of 110 questionnaires were collected and the results were analyzed. Results: Most of subjects were found to have correct knowledge on the breast milk feeding. However, only 49% of subjects had awareness of the presence of HMB. Unfortunately, less than half of them could get information about HMB by official way including mass media. In addition, 76% of subjects were found not to want to use HMB. Most important reason was found as a concern on the safety of donor milk including life style of donors, infection controls, and possible nutritional loss of banked milk. Conclusion: The purpose and function of HMB was not widely educated and it seems to be one of most important reasons why women have negative concept about HMB in Korea. Thus, further study is warranted with more numbers of subjects after active public education about the HMB.

  • Objectives: To describe the distribution of social factors, lifestyle habits and anthropometric measurements according to hypertension and Type-2 diabetes. Methods: A cross-sectional study was conducted in Gaza City, Palestine that included 379 patients (20-60 years) who had hypertension and/or diabetes. Three groups of patients were involved; 106 hypertensive (HT), 109 diabetic (T2DM) and 164 hypertensive diabetics (HT + T2DM). Results: The HT + T2DM group were older and had a higher body mass index compared to HT and T2DM groups. There were 62.3% patients who were female, 49.2% were highly educated HT patients, and 49.3% patients had a low level of education and were HT + T2DM. There were 55.8% patients who lived in large families. Patients who were passive smokers or never smoked before were mostly HT + T2DM, while active smokers and past smokers had T2DM. There were 48.2% patients who were highly physically active who had HT, 40.9% whom were moderately active had T2DM, and 53.8% of patients who had a low level of activity were HT + T2DM. Multivariate linear regression showed that having a diseased mother, living in a large family, being a past or passive smoker, or never having smoked, having a low or moderate level of activity, and having HT or HT + T2DM, were significantly associated with an increased body mass index. Conclusion: Parental health/disease conditions and environmental factors (social network and lifestyle habits) played the greatest role in the development of obesity and disease.

  • Background: Non-cardiac chest pain (NCCP) is a common patient complaint imposing great costs on the healthcare system. It is associated with psychological factors such as depression. The aim of the present study is determining depression predictors in NCCP patients. Methods: The participants of this cross-sectional study were 361 NCCP patients. Patients filled out questionnaires concerning their sociodemographic, lifestyle, and clinical factors (severity of pain, type D personality, somatization, cardiac anxiety, fear of body sensations, and depression). Results: Based on multiple ordinal logistic regression, lack of physical activity (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.09-2.87), sleep quality (OR, 2.98; 95% CI, 1.15-7.69), being a smoker (OR, 1.33; 95% CI, 2.41-4.03), present pain intensity (OR, 1.08; 95% CI, 1.05-1.11), type D personality (OR, 2.43; 95% CI, 1.47-4.03), and somatization (OR, 1.22; 95% CI, 1.15-1.3) were significant predictors of depression in NCCP patients. Additionally, multiple linear regression showed that being unmarried (β = 1.51, P = 0.008), lack of physical activity (β = 1.22, P = 0.015), sleep quality (β = 2.26, P = 0.022), present pain intensity (β = 0.07, P = 0.045), type D personality (β = 1.87, P < 0.001), somatization (β = 0.45, P < 0.001), and fear of bodily sensation (β = 0.04, P = 0.032) increased significantly depression scores in NCCP patients. Conclusions: Physicians should consider the predictors of depression in NCCP patients which can lead to receiving effective psychological consultations and reducing the costs and ineffectual referrals to medical centers.

  • As the rapid pace of modern society, people's daily life is becoming tenser and busier. We need a place to relax and to release our pressure. Coffee shops therefor become one of our best choice. With the strengthening of the expansion of the localized Starbucks coffee shop, it becomes extremely urgent for other coffee shops to enhance the space environment design to become outstanding in the coffee shop market. This paper researches and compares the indoor environment design of Starbucks coffee shops in four cities in China, namely Shanghai, Suzhou, Shenzhen and Beijing and four cities in Korea, namely Busan, Seoul, Seoul and Jeju. By comparing the design characteristics and the style of the interior environment of Korea-China coffee shops, we analyze the various elements of space design and summarize the differences in the environmental design of Korea-China Starbucks coffee shops. Moreover, we propose the strategic direction for the future design and the future development of coffee shops. The survey results show that the indoor environment design of Starbucks coffee brand mainly highlights the regional cultural characteristics. Starbucks shops utilize the fashion culture elements based on the local economic and cultural characteristics, aiming at creating a characteristic coffee brand culture and promoting the vigorous development of the coffee market.
