  • The purpose of this study was to examine the research trend of nutrition for the recent 12 years from 1996 to 2007 by analyzing 734 articles published in the Korean Journal of Community Nutrition. The majority of the articles (61.4%) were classified as survey types in terms of data collection methods. Most of the subjects used in the articles were adults (28.8%), and the subject whose research has been increased at the highest rate was "patients". The most frequent keywords in the title of articles were "nutrient intake" (231times), "food service" (92times), "dietary habits" (69times), and "obesity" (69times). The keywords that have appeared more frequently with the years were "osteoporosis" (450.0%), "menopause" (350.0%) and "dietary attitudes" (208.3%). As for research interests, "nutrient intake" was dominant in the early stage of research while "disease", "dietary habits", "dietary attitudes" and "nutrition education" have increased in recent years. Some of the most common methods of nutrition assessment were "dietary intake" (41.2%), "anthropometric" (34.0%) and "biochemical test" (14.7%). The most common methods of dietary intake were "24-hours recall" (28.6%) and "dietary habits" (23.3%). The results of this study showed some biases in data collection methods, gender of the subjects, and study areas. Moreover, inconsistent terminologies, questionnaire contents, and measures were used for the researches on dietary behaviors, dietary habits, dietary attitudes, which made it difficult to compare their results for each research. Therefore, standardized research methods and terminologies need to be developed regarding dietary practices.

  • Purpose: The purpose of this study was to investigate the relationship between relative handgrip strength (HGS/BMI) and obesity (BMI above 95th percentile) in adolescents. Methods: The subjects of the study were 637 out of 701 adolescents aged 10~18 who participated in the 2018 National Health and Nutrition Survey (KNHANES), excluding those with missing values in body mass index (BMI) and handgrip strength (HGS). The relative handgrip strength (HGS/BMI) value was divided by quartile and composite sample logistic regression analysis was performed to see its relationship with obesity (BMI above 95th percentile). The collected data were analyzed using SPSS 18.0. Results: As a result of analyzing HGS according to gender-specific quartiles, age, height, and weight of male adolescents increased significantly as HGS/BMI increased (p trend<.001). In addition, as HGS/BMI increased, total cholesterol, triglycerides, and HDL cholesterol decreased significantly (p trend<.001). In the case of female adolescents, age and height increased significantly as HGS/BMI increased (p trend<.001). HGS/BMI was lower in the obese group (p=.023), while total cholesterol was higher in the obese group(BMI above 95th percentile) than in the non-obese group. As a result of the composite sample logistic regression analysis, the odds ratio (OR) decreased significantly as the quartile increased in both male and female adolescents. Conclusion: According to these results, a follow-up study is needed to confirm the factors affecting muscle strength of adolescents. In addition, this study intends to be used as basic data to conduct further research and to develop programs that can improve muscle strength and reduce obesity in adolescents.

  • Holding the longest observation data from April 1904, Busan is one of the essential points to understand the climate variability of the Korean Peninsula without missing data since implementing the modern weather observation of the South Korea. Busan is featured by coastal areas and affected by various climate factors and fluctuations. This study aims to investigate climate variability and changes in climatic variables, extremes, and several weather indexes. The statistically significant change points in daily mean rainfall intensity and temperature were found in 1964 and 1965. Based on the change point detection, 117 years were divided into two periods for daily mean rainfall intensity and temperature, respectively. In the long-term temperature analysis of Busan, the increasing trend of the daily maximum temperature during the period of 1965~2021 was larger than the daily mean temperature and the daily minimum temperature. Applying Ensemble Empirical Mode Decomposition, daily maximum temperature is largely affected by the decadal variability compared to the daily mean and minimum temperature. In addition, the trend of daily precipitation intensity from 1964~2021 shows a value of about 0.50 mm day-1, suggesting that the rainfall intensity has increased compared to the preceding period. The results in extremes analysis demonstrate that return values of both extreme temperatures and precipitation show higher values in the latter than in the former period, indicating that the intensity of the current extreme phenomenon increases. For Wet-Bulb Globe Temperature (effective humidity), increasing (decreasing) trend is significant in Busan with the second (third)-largest change among four stations.

  • BACKGROUND/OBJECTIVES: Prior studies, mostly conducted in Western countries, have suggested that the low cost of energy-dense foods is associated with an increased risk of obesity. This study aimed to investigate the association between food costs and obesity risk among Koreans who may have different food cost and dietary patterns than those of Western populations. SUBJECTS/METHODS: We used baseline data from a cohort of 45,193 men and 83,172 women aged 40-79 years (in 2006-2013). Dietary intake information was collected using a validated food frequency questionnaire. Prudent and Western dietary patterns extracted via principal component analysis. Food cost was calculated based on Korean government data and market prices. Logistic regression analyses were performed to investigate the association of daily total, prudent, and Western food cost per calorie with obesity. RESULTS: Men in the highest total food cost quintile had 15% higher odds of obesity, after adjusting for demographic characteristics and lifestyle factors (adjusted odds ratio, 1.15; 95% confidence interval, 1.08-1.22; P-trend < 0.001); however, this association was not clear in women (P-trend = 0.765). While both men and women showed positive associations between prudent food cost and obesity (P-trends < 0.001), the association between Western food cost and obesity was only significant in men (P-trend < 0.001). CONCLUSIONS: In countries in which consumption of Western foods is associated with higher food costs, higher food costs are associated with an increased risk of obesity; however, this association differs between men and women.

  • Forecasting have qualitative and quantitative methods. Quantitative one analyze macro-economic factors such as the rate of exchange, oil price, interest rate and also predict the micro-economic factors such as sales and demands. Applying various statistical methods depends on the type of data. when data has seasonality and trend, Time Series analysis is proper but when it has casual relation, Regression analysis is good for this. Time Series and Regression can be used together. This study investigate artificial neural networks which is predictive technique for casual relation and try to compare the accuracy of forecasting between regression analysis and artificial neural network.

  • This study examines research trends in the dissertations and theses on fashion illustration, as part of the necessity of the enlargement of this field into different areas and the importance of fashion research that will in the future. Currently, there are efforts to find the state of pervasive trends in thesis or that of dissertations in this area to help deter existing studies from producing mutually supplementary and constructive results. This also includes research that may have been overlapped in part or biased toward particular fields. This study is to solidify the research trend in papers and dissertations on fashion illustration in fields unexamined to suggest some of the right direction for research and development in fashion illustration. The selected data involved papers and dissertations published between 1990 and April 2009 by domestic graduate schools. To understand the research trend by item, descriptive statistics are utilized to acquire statistical data on the frequency and percentage in the creation of graphs. The findings of the study are as follows: There has been a steady increase in the rates of the theses and dissertations in this field in yearly domestic research fashion trends in illustration since 2002. In terms of the annual trend by the type of research, the number of the theses and dissertations on the production of works is larger than that of theoretical ones. This indicates that more attention should be given to theoretical research in this area. In regard to research themes and methods, many theses and dissertations were included with the production of works that showed a need to diversify the scope of research.

  • Classifying clothing fabrics into fashion images lacks research, but is necessary due to the short cycle of fashion and rapidly changing modern trends as consumers seek to satisfy various needs with an increase of online purchases. There is also a lack of research on fashion trend books which attach real fabrics. Therefore, this study aims to help the planning field by recognizing fabric sensibility related to the fabric image perceived by consumers. The data analysis results from descriptive statistics, t-test, and ANOVA using SPSS are as follows: Differences in the visual tactility evaluation related to the consumer recognized fabric images showed more significant differences in F/W seasons. The elegance image was shown as relatively thick, the avant-garde image was shown as relatively heavy, thick fabric. The feminine image was shown as relatively thin and smooth fabric, the sporty images were shown to be moist, flexible and elastic, and the mannish images were relatively rough. The romantic images were shown as relatively thin fabrics. The conclusions inferred from the visual tactile evaluation related to the fabric images recognized by consumers vary by major, so the prior information concerning fabrics and trends can affect the selection of images. The results of this study show that in order to produce clothes suitable for fashion product planning by learning about visual tactility that consumers recognize, fabrics component data displayed in fashion trend books from 2016 to 2018 are needed, so the planner can receive help when selecting the fabrics suitable for each trend.
