The purpose of this study is to investigate recognition degree and acceptability of fashion trends of new consumers who live in digital era, and to determine how these factors have influence on their use of fashion trend information. The study was conducted with 696 people from 15 to 34 years old. A self-administrated questionnaire based on the results of previous researches was developed. The data were analyzed with statistical analyses such as frequency analysis, mean, factor analysis, t-test, ANOVA, correlation and regression analysis. The results are as follows: first, new digital consumer's recognition degree (RD) of fashion trends is 7.85 on the average, given that the top of scale is 20.0, it is quite low. Of fashion trend RD, fashion item RD is the highest. The female subjects recognize fashion trends better than the male subjects. Second, fashion trend acceptance of new digital generation is classified into 5 factors: 'search acceptance', 'lead acceptance', 'follow acceptance', 'non-acceptance', and 'delay acceptance'. The female subjects show higher degree in the factors of 'search acceptance', 'lead acceptance' and 'follow acceptance' of fashion trend than the males; hence it means that the females have more positive attitudes in fashion trend acceptance than the males. Third, there are significant differences between genders in the fashion information utilization. Compared to the males, the females more use fashion information on style, fabrics and color. Concludingly, their fashion trend recognition degree and acceptance made an influence in part on their utilization of fashion information.

This study reviewed on the research trend of sources and utilization of the byproducts(Lignin) from bioethanol production process with lignocellulosic biomass such as wood, agri-processing by-products(corn fiber, sugarcane bagasse etc.) and energy crops(switch grass, poplar, Miscanthus etc.). During biochemical conversion process, only Cellulose and hemicellulosic fractions are converted into fermentable sugar, but lignin which represents the third largest fraction of lignocellulosic biomass is not convertible into fermentable sugars. It is therefore extremely important to recover and convert biomass-derived Lignin into high-value products to maintain economic competitiveness of cellulosic ethanol processes. It was introduced that lignin types and characteristics were different from various isolation methods and biomass sources. Also utilization and potentiality for market of those were discussed.

Objective: This study is performed to investigate the trend of health care (HC) utilization among cleft lip and/or palate (CL/P) during 2007-2016 by using data from the Korean National Health Insurance Service (KNHIS). Methods: The KNHIS data were reorganized to count a specific patient only once for a specific year. Cleft type (cleft lip [CL], cleft palate [CP], and cleft lip and palate [CLP]), sex, and age at HC utilization were investigated. The study period was divided into the first half (2007-2011) and the last half (2012-2016). The utilization number and rate per 1,000 population were calculated for the total population and for new-born patients. Independent t-test and one-way analysis of variance were used for statistical analyses. Results: The total CL/P population (n = 48,707) comprised 19.2% CLP, 35.5% CL, and 45.3% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 0.066 in 2007 to 0.118 in 2016. The new-born patient population (n = 7,617) comprised 18.6% CLP, 30.4% CL, and 51.0% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 1.12 in 2007 to 1.74 in 2016. An examination of the utilization number and rate among new-born patients revealed CP exhibited a female-dominant pattern (all p < 0.01), while CL and CLP exhibited a male-dominant pattern (all p < 0.01). However, utilization number showed no difference by sex and cleft type between 2007-2011 and 2012-2016. Conclusions: These results might serve as a guideline for HC utilization among patients with CL/P.

Objectives: Although Korean Medicine (KM) subsidized by the National Health Insurance (NHI) has been used for a long time, there has been no active analysis using claims data. Therefore, the purpose of this study was to examine the NHI KM utilization trend using NHI statistics and to measure the level of market concentration by year. Methods: By restructuring the contents of NHI Statistics for Pharmaceuticals for 2010-2019, the claim cases, costs, and annual growth rates of KM were demonstrated by year, sex, age group, region, therapeutic group, and KM treatment. The proportion of highly used k treatments in cost was calculated as the concentration ratio (CR) k and its trend by year was investigated. Results: In 2019, the NHI cost on KM amounted to ₩38.2 billion KRW, increasing by 11.6% per year on average in 2010-2019. Notably, KM was used more frequently among women and patients aged ≥ 65 years, and the mixed formulation accounted for 95% of the total cost of KM. The CR of the simple formulation increased rapidly, whereas that of the mixed formulation remained constant. In 2019, three simple formulation treatments- peony, licorice, and ginseng- accounted for 93.8% of the total cost for KM (CR3 = 93.8%). Conclusion: NHI KM is rapidly increasing. Investigating the CR of KM confirmed that KM prescriptions have been concentrated in small numbers over the past 10 years.

Objectives : This study aimed to analyze the structure and the trend of utilization and expenditure for Korean Medicine (KM) in Korea. Methods : Data were drawn from the 2008-2013 annual Korea Health Panel (Version 1.2.2), a national representative sample. We combined the data of household members with the data of outpatient KM service use. The volume of KM use was estimated based on the frequency of use and co-payment. Results : The KM utilization rate slightly increased in recent years, and it is presumed to be resulted from the increase of elderly population. Most KM outpatient visits were being concentrated in treating musculoskeletal diseases, and the procedures used frequently were acupuncture, moxibustion, cupping, and physical therapy. The imbalance of KM use between lower income group and higher income group was deepening. Conclusions : To expand restricted disease areas KM covered, the more herbal prescriptions should be insured and the insured form of herbal medicines need to be diversified.

Improving public awareness of wood is crucial for expanding the use of wood and establishing a wood culture. In this study, the environment and trends of the public's wood utilization were analyzed using a questionnaire survey and online text mining at a time when eco-friendly practices are gaining popularity. As a result of reducing climatic and environmental concerns and its positive physical and psychological effects, the use of wood is predicted to rise in areas intimately connected to everyday living, such as wood furniture, wooden structures, and interior materials. Nonetheless, there was a negative awareness that wood was expensive, difficult to maintain, and associated with deforestation. The correlations between wood-related search terms on major Korean portal sites were analyzed and categorized into five groups: Wooden architecture, cultural education, woodworking, wood industry, and wood policy. As a building material, wood was seen as more traditional and friendly than reinforced concrete and stone. Eighty-six percent of respondents expected to utilize wood as a building material in the future, regardless of whether the wood is domestically produced or imported. Sixty-five percent responded favorably about the effects of wood on the health of wooden home inhabitants. It is believed that both active publicity and quantifiable value analysis of human and environmental friendliness are required to increase pro-environment awareness of wood utilization.

In this paper, we reported that the global trend of cement production and utilization as raw materials and as a fuel. As we know, cement is one of the significant materials required for the construction industry. The recent trend of rising urbanization, both the cement and construction industry played a vital role. The cement industry is a major sustainable infrastructure for the countries. Currently, China producing cement half of the world's cement production. During the year 2018, Korea producing cements nearly 57.5 million metric tons. Waste materials are used as circular resources and also having tremendous benefits for cement production. Another important use of these circular resources is fuel for the cement industry. There is a large potential benefit of the cement industry, but it's creating a severe environmental threat. The cement industry contributes to the major emissions of CO2. This leads the global warming. As per the Paris agreement, the Korean government initiated the recycling policy of waste materials and also the utilization of circular resources for the prevention of limited natural resources and also the global warming effect.

Analysis of health care utilization is very important for health care policy development. Traditional studies of health care utilization were focused on measuring the level of health care utilization and on analyzing the determinants of health care utilization in the defined areas and populations. But there were some limitations in comparing the health care utilizations rates in traditional studies because so many factors were to be considered. Small area analysis is a method used to demonstrate substantial variations in health care utilization with popualtion-base use rates among similar geographic areas. This review discusses the methods, magnitude and trend of geographic variations, factors influencing small area variations, and makes suggestions for further study. Finally, the article discusses the necessity and feasibility of small area analysis in Korea.

The desire for a technology that can mechanically acquire 2D images starting with the manual method of drawing has been making possible a wide range of modern image-based technologies and applications over a period. Moreover, this trend of the utilization of image-related technology as well as image-based information is likely to continue. Naturally, as like other technology areas, the function that humans produce and utilize by using images needs to be automated by using computing-based technologies. Surprisingly, technology using images in the future will be able to discover knowledge that humans have never known before through the information-related process that enables new perception, far beyond the scope of use that human has used before. Regarding this trend, the manipulation and configuration of massively distributed image database system is strongly demanded. In this paper, we discuss image identifier production methods based on the utilization of the image hashing technique which especially puts emphasis over an entropy operator.
