The purpose of this study was to investigate the effect of Saengmaeg-san intake on blood lipids and arteriosclerosis index in male tennis players. Seventeen male tennis players enrolled in university were assigned to a Saengmaeg-san intake group (n=9) and a placebo control group (n=8) according to whether they took Saengmaeg-san during 4-week high-intensity tennis training. Tennis training was conducted 5 times a week for 4 weeks, and the exercise intensity was performed at 70-90% of the spare heart rate. The intake of Saengmaeg-san was 110ml at a time before breakfast, before, during, during, and after exercise, and after dinner, a total of 7 times, 770ml per day. For all data, mean and standard deviation were used. Two-way repeated measures ANOVA was used to examine the effect of time and treatment, and Pearson's Correlation was used to examine the relevance of differences in blood lipid responses after treatment. As a result of this study, the Saengmaeg-san intake group significantly improved blood lipids (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) and arteriosclerosis index, and there was a significant correlation appeared between ∆TG, ∆LDL-C, and ∆TC. As a result, the intake of Saengmaeg-san during high-intensity training of male college student tennis players can have a positive effect on blood lipids and arteriosclerosis index, suggesting that it can be an effective sports drink as an exercise supplement.

Purpose: This study was to investigate the correlation between pain, disability and quality of life among adolescents and office workers with neck and shoulder pain. Methods: Twenty-four subjects (mean age=24.92 years, SD=3.94, range=20-37) with neck and shoulder pain participated in this study. The outcome measures of the study were visual analogue scale (VAS), neck disability index (NDI), shoulder pain and disability index (SPADI), short form-36 (SF-36) for neck and shoulder pain and disability, quality of life. Pearson's correlation and Speaman's rank correlation were used to measure the association between VAS and NDI, SPADI, SF-36. Results: The VAS showed a positive correlation between weak to moderate with the NDI and SPADI, but no significantly correlated (${\rho}=0.34$, ${\rho}=0.25$). The moderate positive correlation and significant correlation were observed between NDI and SPADI (${\rho}=0.43$, p<0.05). The PCS of SF-36 was significantly negative correlated with the VAS (${\rho}=-0.24$), NDI and SPADI (${\rho}=-0.63$, ${\rho}=-0.59$, p<0.05). Conclusion: The pain and disability of neck and shoulder has closely relevance. And, the pain and disability of neck and shoulder has a negative impact on the quality of life.

Epidemiological evidence of the effects of dietary sodium, calcium, and potassium, and anthropometric indexes on blood pressure is still inconsistent. To investigate the relationship between dietary factors or anthropometric indexes and hypertension risk, we examined the association of systolic and diastolic blood pressure (SBP and DBP) with sodium, calcium, and potassium intakes and anthropometric indexes in 19~49-year-olds using data from Korean National Health and Nutrition Examination Survey (KNHANES) III. Total of 2,761 young and middle aged adults (574 aged 19~29 years and 2,187 aged 30~49 years) were selected from KNHANES III. General information, nutritional status, and anthropometric data were compared between two age groups (19~29 years old and 30~49 years old). The relevance of blood pressure and risk factors such as age, sex, body mass index (BMI), weight, waist circumference, and the intakes of sodium, potassium, and calcium was determined by multiple regression analysis. Multiple regression models showed that waist circumference, weight, and BMI were positively associated with SBP and DBP in both age groups. Sodium and potassium intakes were not associated with either SBP or DBP. Among 30~49-year-olds, calcium was inversely associated with both SBP and DBP (P = 0.012 and 0.010, respectively). Our findings suggest that encouraging calcium consumption and weight control may play an important role in the primary prevention and management of hypertension in early adulthood.

This study was conducted to compare the nutritional status, nutrient intakes, and chronic disease risks of Chinese elderly people. MNA (Mini Nutritional Assessment) developed for elderly people was used to determine their nutritional status. In this study, participants consisted of 148 urban residents aged 65 years and over residing in three cities in Shandong Province, China. Participants were 67 (45.3%) men and 81 (54.7%) women, and average age was 72.8 years. According to MNA score, 77.7% of participants were 'well nourished', 22.3% were 'at risk of malnutrition', and 2% were 'malnourished'. Nutritional status was divided into two groups by MNA score as 'well nourished' and 'malnourished', which was formed with the combination of 'at risk of malnutrition' and 'malnourished'. Compared with the well nourished group, the malnourished group was older, and physical status indicators such as weight, BMI (Body Mass Index), and calf circumference of the malnourished group were much smaller. The malnourished group had higher prevalence rates of heart disease and stomach disorders while the well nourished group had a higher rate of hypertension. There was no significant difference between the malnourished group and well nourished group in nutritional intake below Chinese DRIs (Dietary Reference Intakes) among elder males. A higher proportion of elder females showed insufficient intakes of energy, protein, vitamin A, vitamin E, and zinc in the malnourished group compared to the well nourished group. The INQ (Index of Nutrition Quality) of calcium, magnesium, zinc, iodine, and most vitamins was less than 1 in both the malnourished and well nourished groups.

Community question and answering service is one of the main sources of information and knowledge in the Web. The quality of information in question and answer documents is determined by the clarity of the question and the relevance of the answers, and the readability of a document is a key factor for evaluating the quality. This study is to measure the quality of documents used in community question and answering service. For this purpose, we compare the frequency of occurrence by vocabulary level used in community documents and measure the readability index of documents by institution of author. To measure the readability index, we used the Dale-Chall formula which is calculated by vocabulary level and sentence length. The results show that the vocabulary used in the answers is more difficult than in the questions and the sentence length is longer. The gap in readability between questions and answers is also found by writing institution. The results of this study can be used as basic data for improving online counseling services.

Objectives : In this study, we diagnosed Mibyeong group of adult by taking into Mibyeong Index consideration, and identified the correlation of a Mibyeong group with cold-heat pattern and life quality of them. Methods : The questionnaires were collected by Gallup Korea professional surveyor through face to face interviews. To analyze the differences between health and mibyeong group, we used the descriptive statistics, Pearson's correlation, ANOVA. And multinomial logistic regression was used to generate the odds ratios (ORs) and 95 % confidence interval (CI) for the differences between health and mibyeong group. Results and Conclusions : The gender composition of respondents in this study that there 545 male (49.5%) and 555 female (50.5%). The score of both cold pattern(health: $21.33{\pm}4.25$, MI 1: $22.43{\pm}4.29$, MI 2: $24.09{\pm}5.03$; post hoc test, p <0.001) and heat pattern(health: $18.4{\pm}4.01$, MI 1: $19.48{\pm}4.10$ MI 2: $19.88{\pm}4.81$; post hoc test, p <0.001) in mibyeong group is higher than the score health group. And, these result have no relevance to age. The score of both Physical component summary (PCS) and Mental component summary (MCS) in health group is higher than the score mibyeong group. Cold-heat pattern and quality of life vary significantly according to health status. This results suggest the analysis of cold-heat pattern and quality of life by health status could provide the setting of direction to promote public health depending on health status.

The relevance of the research is due to the fact that the issue of poverty is one of the most acute social problems of the beginning of the third millennium. The phenomenon of poverty is widespread in third world countries as well as it is observed in relatively developed countries. Poverty rates in Latin America are threatening. Consequently, the issue of social and economic inequality in these countries has become extremely acute. The purpose of the research: to identify the causes of poverty and social inequality and substantiate the main directions of poverty reduction in third world countries. The research methods: comparative analysis; index method; systematization; grouping; generalization. Results. The classification of the causes of poverty has been carried out and the directions of its overcoming in the countries of Latin America on groups of indicators have been defined, namely: 1) political; 2) economic; 3) demographic; 4) regional-geographical; 5) social; 6) qualification; 7) personal. Based on the Net Domestic Product indicator, a comparison of economic indicators of the studied countries has been carried out. It has been revealed that from 1990 to 2018 income inequality increased in 52 of 119 countries studied, and decreased in 57 states. Inequality has increased in the world's most populous countries, particularly China and India. In general, countries with growing inequality are home to more than two-thirds (71%) of the world's population. Trends in the distribution of income in the world have been investigated by applying the Gini index, the high level of which is observed in Latin America (Colombia 48,9%, Panama 46,1%, Chile and Mexico 45,9%). The forecast of the impact of the Covid-19 pandemic on this issue has been outlined; the ways of its impact on the economies of the countries have been studied. As a result of the study, the main directions and mechanisms of the strategy for poverty reduction and social inequality in the third world countries have been identified. The implementation of the poverty reduction strategy presented in this academic paper may have a positive impact on the economic situation of the population of Latin American countries.

Since the onset of the COVID-19 pandemic, there has been a significant shift in the lifestyle patterns of the populace across various domains. Concerns surrounding COVID-19 have emerged as pivotal catalysts of change in recreational habits with people giving a particular preference for environments with low population density and increased openness. This trend has resulted in an uptick in excursions to natural reserves, coastlines, and parks. However, during the peak of infectious outbreaks, widespread adherence to social distancing measures has precipitated a steep decline in tourist footfall across natural recreation forests, exacerbating financial deficits to a considerable extent. Thus, this research sought to compare and analyze the operational efficacy and productivity of national, public, and private natural recreation forests pre- and post-COVID-19 pandemic by utilizing non-parametric methodologies, such as data envelopment analysis and the Malmquist productivity index analysis. The objective was to identify the factors contributing to the decreases in efficiency and productivity and ultimately offer nuanced recommendations tailored to respective administrative bodies. This study's distinctive focus on the analysis of management efficiency and productivity in natural recreation forests nationwide offers significant academic and practical relevance.
