We researched the modern meanings of traditional dining table courtesy education and its correlation with the main values of contemporary personality education based on dining table courtesy education stated in the social norms texts of the Joseon dynasty. Among the social norms of the Joseon dynasty, we chose Sohak, Naehun, Dongmongsuji, Seonghakjibyo, Gyeongmongyogyeol, Jeungbosallimgyeongje, Sasojeol, and Koamgahoon for research. As a result of our research on these documents and books, the modern meanings of the courtesy education at the dining table can be summarized as follow. First, the courtesy education has table manners appropriate for the development level of early children. Second, it teaches right-handed dining manners that match the features of Korean food culture. Third, it has the self-discipline and the values of community life, sharing, solicitude, and communication. Fourth, parents and grandparents are involved in the education. Fifth, it has the core values of modern personality education: manners, filial piety, respect, solicitude, communication, cooperation, and responsibility. Future courtesy education at the dining table should include practical education programs that can consolidate the bond of sympathy between the home, school, and society, and can improve its practice; in addition, to expand the opportunities for education, proactive social support is demanded.

In this study, groundwater flow was analyzed targeting Dae-jeong watershed, which exhibited the largest variations of groundwater levels at the identical elevation points among the 16 watersheds of Jeju Island. The issues of the methods applied in practice were identified and improvement plans were suggested. This groundwater-flow estimates derived by applying hydraulic conductivity values onto zones of equal topographic ground level were found to be quite different from actual measured groundwater flow. Conversely, groundwater-flow estimates that utilized hydraulic conductivity values applied onto groundwater-level equipotential lines indicated relatively lesser divergences from actual measured groundwater flow. The reliabilities of the two approaches were assessed for 60 randomly selected points on DEM (digital elevation model) maps, The method using hydraulic conductivity values applied onto groundwater-level contours turned out to be the more reliable approach for the Dae-jeong watershed in Jeju Island.

Best linear unbiased prediction (BLUP) has been used to estimate the fixed effects and random effects of complex traits. Traditionally, genomic relationship matrix-based (GRM) and random marker-based BLUP analyses are prevalent to estimate the genetic values of complex traits. We used three methods: GRM-based prediction (G-BLUP), random marker-based prediction using an identity matrix (so-called single-nucleotide polymorphism [SNP]-BLUP), and SNP-SNP variance-covariance matrix (so-called SNP-GBLUP). We used 35,675 SNPs and R package "rrBLUP" for the BLUP analysis. The SNP-SNP relationship matrix was calculated using the GRM and Sherman-Morrison-Woodbury lemma. The SNP-GBLUP result was very similar to G-BLUP in the prediction of genetic values. However, there were many discrepancies between SNP-BLUP and the other two BLUPs. SNP-GBLUP has the merit to be able to predict genetic values through SNP effects.

Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade $plant{\acute{e}}e$ and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

China's Belt and Road Initiative (BRI) is China's contribution to the need for the world to collectively address deficits of peace, development, governance, and problems relating to climate, the environment and human health. The rise of China and the BRI do challenge the current 'rules-based global order' and the economic dominance and moral, political, economic, and cultural leadership of the United States and its allies. However, China's goal is not hegemony but a multipolar world in which common values coexist with principles of peaceful coexistence (including non-interference in the internal affairs of sovereign states). The evolution of the BRI is outlined, and the ways in which it reflects Chinese interests are summarized, including its roles in addressing natural resource dependence and excess capacity, a transition from investment promotion and factor-intensive growth to going out and industrial upgrading, going West, and the effective deployment of China's foreign exchange assets. Although China does therefore potentially gain, the BRI is designed so that partners also gain in a quest for win-win co-operation and mutual benefit. The values that underlie this approach and the call for a community with a shared future are compared with competing western values, whose roots lie in Enlightenment thought and are associated with a record of colonialism and imperialism. In this light, the article concludes with a consideration of the global implications of the BRI, the challenges it confronts and the likelihood that the unipolar moment will give way to a multipolar global development path.

In recent decades, the socio-hydrology community has developed several socio-hydrological frameworks to understand the complexity of the coupled human-water system. Although there have been efforts to relate sociology and hydrology, there still have been some insights that remain debatable. As for this study, the Value-belief-norm theory was used to represent the human behavior in order to connect the human-water system. The theoretical framework of values, beliefs and norms was developed to understand the human culture towards the environment. In addition to the theory, norms are legislation of human behavior in the society while the values are the guiding principle to motivate beliefs and norms. The overview of this study implied on developing a socio-hydrological model consisting of the four systems defined as hydrology, socio-economy, technology and institutional. The interconnectors between the four systems are the key variables and parameters representing a module namely the causal loop diagram. Moreover, water quality, size of population, infrastructure capacity and norms are the key variables to connect the four systems. The developed model will be applied to Han River to represent the coevolutionary of the dynamics of human-water systems.

The amount and type of dietary protein that effects affect bone mineral loss after menopause and different dietary patterns may influence anthropometric measurements, biochemical values, and bone metabolism. Objective : Our objective was to investigate bone metabolism and chronic disease factors in two different dietary patterns. Design: The sample consisted of 40 lacto-ove-vegetarians(LOV) and 49 omnivores aged from 47 to 85 years in good condition without any medical problems. Results : The average energy intake of LOV was 1414.0kcal and omnivores, 1403.2kcal. The difference between means was not statistically significant. The differences of means of body weight and BMI between the two groups were not significant but the systolic blood pressure of LOV group was significantly lower than omniovores(p<0.05). The values of serum cholesterol(p<0.05) and glucose(p<0.05) of LOV were signifcantly lower than that of omnivores. The serum albumin level(p<0.01) of LOV was lower than it'scounterpart but in a normal range. The intake of crude fiber(p<0.05) of LOV group was significantly higher. The urinary pH of LOV was 7.4 and that of omnivores was 6.3(p<0.001). Plant calcium(p>0.05) and plant iron(p<0.001) had positive correlations with the uninary pH but animal protein(p>0.05) and animal iron(p>0.05) had negative correlations with the urinary pH. The level of urinary biochemical marker of bone resorption, deoxypyridinoline(DPD) of LOV was significantly lower than the other group(p>0.05). The T-scores of bone mineral density for the two sites in the two groups were not significantly different. Conclusions : The DPD level and urinary pH value of LOV were more desirable for the bone metabolism that the omnivores. The diet of LOV had lower risk factors of chronic diseases than the other group.

The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, R$\ddot{o}$hrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.

The information about the physicochemical environments, the species distribution and community of the epilithic diatom cells in Pyengchang river and inflow streams of Gangwon-do were studied for assessment of biological water quality from June 2008 to October 2010. Total 112 diatom taxa were identified with 2 orders, 9 families, 26 genera, 95 species and 17 varieties. Among the total taxa identified, 13 taxa, 52 taxa and 15 taxa represented the family Achnanthaceae, Naviculaceae and Bacillariaceae, respectively. The pH values of the water was found to be neutral to alkaline due to the limestone grounds of Pyengchang river and inflow streams. The 13 taxa including Epithemia adnata, belonged to alkaline-water diatoms, and three species - Cymbella japonica, Eunotia major and Fragilaria capitellata - are known to be acidic-water species. The species, Hannaea arcus, known as a cryophilic and mountain periphyton was identified at IF2, IF3 and IF4 in low water temperature environments at high altitudes, being a dominating species in P1 and IF1. Four saproxenous species - Achnanthes convergens, Cocconeis placentula var. lineata, Cymbella turgidula and Hannaea arcus - were dominant at some sampling sites. For biological water quality assessment, IF2, IF3 and P3 showed low water quality class. The values of DAIpo and TDI were 10.6 ~ 98.0 and 13.8 ~ 94.2, respectively. Therefore, biological water quality in Pyengchang river and inflow streams was relatively desirable.
