A total of 100 adults were surveyed on types of favorable meat products. They tended to show much of unsatisfactory on the market products. Those unsatisfactory were mostly conceptual such as instant products, unreliable raw materials, sanitation conditions, list of unfavorable ingredients, mix of harmful additives, and etc. The results indicated that the consumers purchased the products of ham, cheese, chicken, sausages, and canned products mostly at medium-large marts(56%), department stores(22%), retail stores(19%) and others(3%). They were also concerned with the distribution date, prices, shape of packaging, and etc. The types of products and frequencies of purchasing various products were varied by time. For the purchase of products, mixed items were more favored rather than the single items.

E-cigarettes were considered safe at the early stage of market entry because they were thought not to contain harmful ingredients such as nicotine and because the smoke emitted was vapor. For this reason, the use of e-cigarettes as a safer alternative to tobacco cigarettes or as a smoking cessation aid has emerged. However, the study results on the effectiveness of e-cigarettes for smoking cessation are mixed. In response to the increased use of e-cigarettes, foreign countries have implemented various regulations, such as utilizing e-cigarettes for smoking cessation with a prescription in Australia; however, South Korea is still standing firm on recommending not to use e-cigarettes at all. Therefore, the effectiveness of e-cigarettes for smoking cessation and the regulatory trends of e-cigarette use overseas will be reviewed to discuss the future direction in South Korea needs to take.

본 연구에서는 합리적인 수질관리를 위해서 하천의 자정능력을 고려하여 안성천 유역 내 유해성분 중 ABS(음이온 계면활성제)성분에 대해서 QUAL2E모형을 이용하여 위해성평가를 실시하였다. 수질모의결과 안성천과 진위천에서 BOD, ABS의 실측치와 예측치가 비교적 잘 일치함을 보여주고 있으며, DO에 대해서는 예측값과 실측값 사이에 오차가 발생하지만 농도변화의 추이는 잘 나타내고 있었다. 위해성지수는 오염물질의 예상 노출농도(PEC)와 하천수질에 영향을 주지 않는 예상무영향농도(PNEC)를 통해 계산하였고 위해성 비를 산정하여 위해성 지수를 평가하였다. ABS가 하천의 자정작용에 미치는 영향 분석 결과는 안성천[0.0003(Bressan), 0.06(환경부기준)], 진위천[0.0002(Bressan), 0.04(환경부기준)], ABS가 하천의 수생생태계에 미치는 영향에 대한 분석 결과는 안성천[0.0667(Bressan), 0.005(환경부기준)], 진위천[0.1(Bressan), 0.0075(환경부기준)]으로 국립환경과학원고시 제2012-30호에서 제시되어 있는 위해성이 있다고 판단되는 위해성 비의 기준치 값 1보다 작아 하천의 자정능력과 하천의 수생생태계에 영향을 주지 않은 것으로 분석되었다. 본 연구에서 적용된 방법은 간단하며 현재 환경부 수질기준보다 상세히 유해성분에 대한 정보를 줄 수 있다고 판단된다.

Due to the increase in consumers' interest about well-being, interest in eco-friendly products has been increasing due to the harmful effects of various harmful substances contained in textile products and environmental issues. As a result, natural dyes of less potential risk than synthetic dyes and digital textile printing(DTP) textile products with less environmental pollution are drawing attention. However, due to the lack of evaluation criteria for DTP textile products with natural ink and the nature of many colors are stacked layer by layer for dying, the need for simultaneous analysis is emerging. To evaluate whether the natural dye is derived from natural ingredients, the biocarbon content is analyzed. However, in the case of ink made using natural dyes and DTP textile products using natural ink, it is difficult to analyze the biocarbon content due to the limitation of the presence of a small amount of dye contained therein. In this study, we were shown the possibility of natural derived verification by cross-checking the analytes of natural dyes (Persicaria tinctoria, an indigo dye; Dactylopius coccus, a light red; and Curcum longa L., i.e., turmeric) and natural ink with HPLC-MS/MS. The coefficient of determination was 0.999 or higher, the limit of quantification was 0.647-3.664 ㎍/L and a %RSD of each indicator material was less than 10. Then, the extraction amount of natural dyes for five patterned fabrics was analyzed.

Sewage facilities are positively necessary for environment improvement such as rainwater removal, sewage disposal, preservation of the qualify of water and health of the citizens in present-day. Meanwhile, a deterioration of the concrete sewer pipe is increasing rapidly due to the chemical and physical attack and especially biochemical attack that is to say biodeterioration. In this study, researches for the development of antibiotics and antimicrobial concrete were conducted to reduce biochemical corrosion of sewage concrete. First of all, desired performance, such as watertightness, antibiosis, homogeneity, workability and harmlessness, was proposed and performance of antibiotics and antimicrobial concrete were evaluated by them. And developed antimicrobial concrete was applied to actual construction field. As results of this study, dispersibility and antibiosis of liquid antibiotics superior to powdery antibiotics. Antibiosis of antimicrobial concrete was verified, and amount of elution of harmful and effective ingredients was little. In workability, setting time of antimicrobial concrete was delayed. Compressive strength and resistance to carbonation of antimicrobial concrete were more increased than ordinary concrete. Finally, as there were no problems in quality and construction progress of antimicrobial concrete produced in plant, applicability of antimicrobial concrete to actual construction field was verified.

Jookrhyuk (Bambusae Caulis in Liqamen) is one of the most important ingredients for treating Diabetes mellitus. Various aspects of quality of Jookrhyuk produced in Korea depending on carbonization process were compared. The pH Value was the highest in Jinyoungsangsa Jookrhyuk(pH 3.17) among the three different Jookrhyuk samples. Damyangsan Jookrhyuk that contains high level of total sugars(8.0 Brix, %) show incresed level of tar contents, it exhibited positive realationship between total sugar and tar contents. Concentration of methanol and phenolic compounds which are related to toxicity were the highest in Damyangsan Jookrhyuk(1.34㎎/㎖, 3.84㎎/㎖ respectively). The harmful heavy elements were not found in the evaluated Jookrhyuk samples. In coclusion, it was suggested that Bambusae Caulis in Liqamen should be further puryfied for using as main oral medicines for treating Diabetes mellitus.

The number of children wearing make-up is increasing. "Children's cosmetics" is not a legal term though it is commonly used. The purpose of this study is to analyze discussions on children's cosmetics based on news articles found on the internet. This study also identifies what products are being distributed as children's cosmetics. Keyword searches were conducted using internet portal sites. Information was extracted from news articles and Best Item 100 for children's cosmetics. The results of analyzing news articles and Best Item 100 lists are as follows : 1. There were two main discussion topics in news articles. The first topic was related to marketing(the branding and trends of children's cosmetics). The other topic was about government regulations(side effects, harmful ingredients, control, regulations, attention, proper product usage, product categorization, and the overall safety of children's cosmetics). By 2014, many articles had covered government control and regulation. However, since 2017, news articles have focused on the product categorization and the concern for overall safety has dramatically increased. 2. Three different product categories have appeared in the Best Item 100; they are cosmetics, toys, and other products. In market, consumers recognized children's cosmetics as cosmetics and also as toys. Between 2017 and 2018's Best Item, other products are dramatically down, color cosmetics and single cosmetics are on the rise, and the purchase of domestic products has increased.
