As people seek a healthy, wealthy, and quality life more than before, interests in mineral water are picking up and the consumption continues to increase accordingly. In an experiment to examine changes in the water quality after mineral water on the market was kept indoor and outdoor for four weeks, there seemed to be no problem in external appearance. Water kept in an outdoor storage contained more odor-savor than water kept in an indoor storage. Odor was not detected in 90% of the sample, and savor not in 80% of it. As for the mechanism of odor-savor generation, the elution of chemical substances from a container may be taken into consideration. In general, odor and savor have turned out to be in close correlation to each other. The average number of bacteria in the sample mineral water was $200{\pm}10CFU/mL$, and such factors as area of storage and ozone post-treatment did not cause significant effects on the reproduction of common microbes. Hence, it is thought that strict regulations on a production process and reduction of the period of circulation will contribute to customers consumption rates.

BACKGROUND/OBJECTIVES: The coronavirus disease 2019 (COVID-19) outbreak has dramatically changed nearly every aspect of our lives. Although Dietary lifestyle includes attitudes and behaviors to meet their most basic needs, but few studies have examined the pattern of changes in dietary lifestyle driven by COVID-19. This study explores changes in dietary attitudes and behaviors among Korean consumers after COVID-19. SUBJECTS/METHODS: An online survey was conducted with 549 Korean adults aged 20 and older to identify general demographics and changes in dietary attitudes and behaviors. Data were collected from Oct 12 to Oct 18, 2020. Frequency, percentage, and mean values were calculated and a K-means cluster analysis was performed to categorize consumers based on the 5S of dietary attitudes (i.e., savor-oriented, safety-oriented, sustainability-oriented, saving-oriented, and socializing-oriented). RESULTS: Findings indicate consumers considered safety, health, and freshness to be most important when choosing groceries and prepared meal such as home meal replacement and delivery food. Among the types of services, a large proportion of consumers increased their delivery and take-out services. Regarding retail channels, the increase in the use of online retailers was remarkable compared to offline retailers. Finally, consumers were classified into four segments based on changes in dietary attitudes: "most influenced," "seeking safety and sustainability," "abstaining from savor and socializing," and "least influenced." Each type of consumer exhibited statistically significant differences by sex, age, household composition, presence of disease, and perceived risk of COVID-19. CONCLUSIONS: This exploratory study provides initial insights for future research by identifying various aspects of dietary attitudes and behaviors among Korean consumers after COVID-19.

Charts for the bending moments in the closed rib orthotropic deck plate are derived, based on the method originally introduced by Pelikan and Esslinger. New charts are done for EN 1991-2 traffic load distribution schemes. The governing Huber plate equation is solved utilizing Fourier series for various bridge deck plate boundary conditions. Bending moments are given as a function of deck plate rigidities and span length between cross beams. Old diagrams according to DIN 1072, the new ones according to EN 1991-2 and FE analyses results are compared. For typical bridge orthotropic deck plates, it can be concluded that the new EN 1991-2 traffic loads produce larger mid-span bending moments when two lane schemes are used, then those of DIN 1072. For support moments, DIN 1072 gives larger values for any number of lanes, especially under span lengths of 5m. The relevant differences are up to 25%.

The Ritz method is known as very successful strategy for discretizing continuous problems, but it has never been used for solving systems of algebraic equations. The Iterated Ritz Method (IRM) is a novel iterative solver based on the discretized Ritz procedure applied at each iteration step. With an appropriate choice of coordinate vectors, the method may be efficient in linear, nonlinear and optimization problems. Additionally, some iterative methods can be explained as special cases of this approach, which helps to understand advantages and limitations of these methods and gives motivation for their improvement in sense of IRM. In this paper, some ideas for generation of efficient coordinate vectors are presented. The algorithm was developed and tested independently and then implemented into the open source program FEAP. Method has been successfully applied to displacement based (even ill-conditioned) models of structural engineering practice. With this original approach, a new iterative solution strategy has been opened.

본 연구는 선조대 이원익의 정치활동을 검토하고 정치 행위자로서 선조와 이원익간 비교를 통하여 이원익의 백성관과 정치관의 고찰을 목적으로 한다. 선조와 이원익 모두는 당시 백성들의 삶과 정치의 상황이 매우 절망적인 것을 충분하게 인식하고 있었다. 선조는 정치로부터 백성의 삶으로 접근한 반면에, 이원익은 백성의 삶으로부터 정치에 접근하였다. 전자는 정치가 요구하는 바대로 백성의 삶이 변형될 위험성과 수단화의 위험성이 있다. 후자는 백성의 삶이 정치를 결정할 수 있다. 백성들의 구체적 삶에 대한 이원익의 주목은 관념으로서 백성이 아닌 실재로서 백성의 이해에 대한 강조이다. 이원익은 백성을 지배자와 피지배자라는 이분법적 구조 속에서 인식하지 않고, 공동체 차원에서 백성과 상대(相對)한 계층들간 유기적 관계에 주목하여, 상호간 언어적 소통뿐만 아니라 정신적, 문화적, 기능적 소통 차원에서 이해하였다. 이원익은 지식중심적 질문보다 사태-현상 중심적 질문을 제기하였다. 이원익은 백성의 급선무와 그것의 해결방안의 제시에 주안하였다. 이원익의 주장에서 성리학적 주제들보다 공납, 군역, 요역, 조세 감면과 면제, 그리고 수령임명등과 같은 구체적 문제가 발견되는 이유이다. 이원익이 생각한 백성들의 살아가는 모습은 백성들이 살아갈 마음이 생기게 하고, 백성들의 힘에 여유가 생기고(관민력(寬民力)), 백성들이 자신의 삶을 즐김(낙민생(樂民生))으로서 자신의 삶에 편안해 하는 것(안민(安民))이었다. 그러나 이것이 정치가 지향할 바이지만, 이원익은 백성들의 삶이 국가의 삶을 침해하려고 한다든지, 국가가 백성을 대신해서 살아주려는 방식을 철저하게 경계하였다. 이원익에 있어서 정치의 시작처는 조정이지만 결과처는 백성이었다.

Trace metals in honey have an influence on the taste of honey along with pollens. Western bee honeys, which are mostly collected from acacia, have less than 0.1% of ash. Savor of Korean native-bee honey is thought to be due to the difference of the contents of trace metals. Korean native-bee honeys collected from Jirisan District, which is the greatest producing area of native-bee honey in Korea, showed high contents of ash. Korean native-bee honeys from the districts other than Jirisan District also showed similar results($0.44{\sim}0.83%$ of ash) to those from Jirisan District. Potassium was found to be the principal factor of high content of ash with over 85% of trace metals in ash.

<심야식당>은 서부영화와는 다른 이야기구조를 가지고 있으며 '새로운 인물의 등장->주변의 관심->추억의 음식주문->마스터와의 대화->음식의 효과->행방 묘연->결론'의 구조를 갖는다는 것을 발견했다. <심야식당>에는 여러 가지 미디어적 속성들로 가득 차 있다. 마스터는 샤먼으로서 사람들을 이어주고 연결해주며 음식으로 위로를 건넨다. 또한, 음식의 맛을 전달하는 매체가 아니라 추억을 전달하는 매체라는 점에서 음식은 본연의 메시지를 탈메시지화하고 새로운 메시지를 탈취한다. 이런 점에서 음식을 미디어로 볼 수 있다. 또한, 식당이라는 장소 역시 다양한 미디어이벤트가 펼쳐지고, 풍문의 수사학이 유통되는 공론장의 역할을 함을 확인할 수 있었다. 음식이 우리의 감각을 계발시켜주며 감각비율을 새롭게 재조정한다는 측면에서 맛사지로서의 역할도 수행한다고 할 수 있다. 이런 점에서 <심야식당>의 미디어적 속성은 마샬 맥루한의 미디어이론에 잘 부합된다고 할 수 있다.

This paper is to analyze the past and present consumption pattern of fishes aquacultured in marine waters and thus to draw the policy direction to enhance the competitiveness of marine fish aquaculture in Korea. At present, the volume of meat consumption is surveyed to be more than that of marine fish, but it is revealed that fish consumption will become more increasing in the future according to the rise of the income. The survey shows that the consumption of fish is highest in the fall, and among the various patterns of consumption, live fish, so-called susi, is surveyed to be highly dominant. It is revealed that fish is enjoyed because of the special savor, diverse nutrients, and the prevention of adult diseases. Natural fish Is revealed to be more preferred to aquacultured one due to the sticky flesh quality and the low probability of the remained after the production process antibiotics, so that it is necessary to enhance the taste quality and make a clean cultivation to capture more market demand. Consumption of high-quality fish seems to become high in more than middle class and consumption of fish are estimated to increase in the future, more than that of meat if income level of the people increases. Also, if we try to make our high-quality fish become popular among the public and competible with the imported fish from abroad, it is recommended that they must lower production price by cost reduction and try to differentiate it by taste and environmental safety, etc. It was revealed that the significant factor in demand function for fish is income and it is almost the only factor affecting that demand. Also, it was revealed that the most significant factor affecting preference of fish is income and it Is almost the only factor affecting the preference. Therefore, we can ascertain that if proper goods can be distributed, demand for and preference of fish may increase according to the increase of income in the future.
