Double-diffusive convection with vertical temperature and concentration gradients in thermally stratified fluids has been investigated experimentally using an electrochemical technique. Cupric sulfate-sulfuric acid solution confined between two horizontal copper electrodes was used. The change of thermal and solutal buoyance has no influence on the range of voltage for the limiting current. Due to Soret effect, the onset time of natural convection is delayed as the stabilizing thermal buoyancy decreases. Also, it is found that the shrinkage of the unstabilizing solutal buoyancy makes the onset of natural convection retard. Multi-layered convective phenomena do not appear because cupric sulfate-sulfuric acid solution is thermally stratified, and heat diffuses faster than cupric sulfate solution.

Main Meals of Joseon Dynasty were searched and assessed based on inherited culinary books and related datas. Major grain material of main meals was rice and buckwheat flour was widely used for some kinds of mandu and noodles. Boiled rice, gruel thin gruel and mandu were As the Additional ingredients, m iscellaneous cereals, seafoods, vegetables, potatos, meats were added to substitute of rice and improve of preference. This study reviewed for transition and progressive traces of main meals as its respective periods. Culinary Bookss of Joseon Dynasty, Eumsikdimibang, Yorock, sarlimkyungze, Wonheangeulmijungrieugwe, Eumsikbangmun, Kyuhapchongseo, Joseonmussangsinsikyorijebyup and Korean Traditional Foods were reviewed. Some of the main meals were disappeared, canged its side Foodstuffs to easily acquired foods, and also its cooking methods has been gradually modified into combinient types.

오늘날은 디지털 기술의 발달과 더불어 ‘감성의 시대’라고 불릴 만큼 ‘감성’이 시대를 읽는 주요한 코드의 하나로 주목받고 있다. 감성은 외부의 물리적 자극에 의한 감각, 지각으로 부터 인간의 내부에 야기되는 고차원적인 ‘심리적 경험의 총체’이다. 인간의 감성은 복잡한 심리구조로 이루어져 있기 때문에 예측하거나 파악하는 것이 쉽지가 않지만, 상대방을 이해하고 배려하기 위해, 그리고 상대방에게 나를 이해시키고 설득시키기 위해 필요한 커뮤니케이션의 핵심요소이다. ‘감성’을 적극 활용하여 커뮤니케이션 하는 ‘감성표현의 사회’에서는 논리적이고 이성적인 사실만으로 커뮤니케이션을 하는 것보다는, 인간의 감성과 사회적 감성코드를 파악하여 대인관계와 마케팅 등에 감성을 이용하여 커뮤니케이션 하는 ‘감성커뮤니케이션’이 핵심개념이 된다. 감성커뮤니케이션은 어떻게 이용되는지에 따라 커다란 파급력과 지배력을 갖기 때문에 현대사회에서 매우 중요하다. 감성커뮤니케이션은 논리적 판단이 아닌 감성적 판단에 기초한 미학적 커뮤니케이션이다. 이것은 사람과 사람, 사람과 환경, 기업과 소비자, 대상과 대상이 교감하는 모든 접점을 통해 수용자가 원하는 감성을 전달함으로써 서로간의 감성적 유대관계를 형성하도록 하는 모든 활동을 말한다. 감성커뮤니케이션의 힘은 사람을 움직이는 리더십뿐만 아니라 사람들의 소비 생활에도 적용되어, 소비자의 공감을 이끌어내 브랜드 이미지 제고와 제품 구매로 이어지게 만드는 브랜딩과 마케팅 영역에서도 그 빛을 발하고 있다. 특히 한국사회가 서구사회에 비해 정이 많은 사회임을 고려하면 그 어느 때보다도 감성커뮤니케이션이 지극히 중요한 주제라는 것을 알 수 있다. Nowadays, with the development of digital technology, ‘emotion’ is now in the limelight as one of the main codes for reading the era. The emotion is a high dimensional ‘totality of psychological experience’ that is caused inside of human beings by the senses and perceptions of external physical stimuli. However, Human emotion is hard to grasp or predict because of its complex psychological structure, yet it is a cornerstone of communication to understand, consider and persuade other people. In 'Society of Emotional Expression' where people actively use ‘Emotion’ to communicate, rather than communicating only by logical and rational facts, ‘Emotional communication’ which communicates by using emotions such as interpersonal relationship and marketing by identifying human emotion and social emotion code becomes a vital part. Since Emotional communication can cause a huge impact and domination power depending on how people use it, it has become very important in modern society. Emotional Communication is not logical judgment, but aesthetic communication based on emotional judgment. This refers to all types of activities that create emotional bonds by conveying the emotions that receiver wants, through all connection points-people to people, people to the environment, companies to consumers, objects to objects. The power of Emotional communication is applied not only to the leadership that affects people but also to the consumer’s consumption pattern. In that sense, Emotional communication becomes an important part in branding and marketing areas that lead consumer’s sympathy to improve brand image and increase sales revenue. In particular, considering that Korean society puts more importance on “affection” than Western society, Emotional communication is more important than ever.

The objectives of this paper are to present the heat transfer performances of the enhanced tube for the absorber in the absorption chiller. The absorption chiller is made up of four types of heat exchanger. Among these, the absorber is one of the most important heat exchanger for the heat transfer performance and price of the absorption chiller. The enhanced tubes are attached with serrated fins on the outer surface and ridges in the inner surface. The experimental results show that the overall heat transfer coefficients of the enhanced tubes are more improved than bare tubes. These enhanced tubes are good suggestion for the high performance of the absorption chiller.
