Currently, we are living in the era of digital media that puts the technologies in front which is called digital. Based on the characteristic of 'de-materialistic', human senses have been extended more than ever and there is no exception on those influences. Even though the existence of media seriously brought the identity and value of the painting into a question after the emergence of analog photos, advent of digital photos are raising the wind of new paradigms and values creation more seriously than ever. Unlike analog photos of the past which go through chemical process, true nature of digital photo goes through the digital process which is represented by 0 and 1. This didn't bring the loss of the original, but rather brought the creation of the copy which excels the original through retouching and consequently, destroyed the traditional value which is referred as an original. Like this, digital photo image has aesthetics and value of existence which is differentiated from analog photo because it has essentially different structures and characteristics with analog photo.

This study attempts to estimate the value of the water quality improvement by deriving the equilibrium price of the water pollutant emission permit for the imaginary water pollutant emission trading market. It is reasonable to say that there is already an implicit social agreement for the unit value of water pollutant, when the government set the Total Water Pollutant Loading System for the major river basin as a part of the Comprehensive Measures for Water Management, particularly for the Nakdong River Basin. Therefore, we can derive the unit value of water pollutant emission, which is already implied in the pollution allowance for each city or county by the Total Water Pollutant Loading System. Once estimated, it will be useful to the economic assessment of the water quality related projects. An imaginary water pollutant emission trading system for the Nakdong River Basin, where Total Water Pollutant Loading System is already effective, is constructed for the estimation of the equilibrium price of water pollutant permit. By estimating marginal abatement cost curve or each city or county, we can compute the equilibrium price of the permit and then it is regarded as the economic value of the water pollutant. The marginal net benefit function results from the relationship between the emission and the benefit, and then the equilibrium price of permit comes from constructing the excess demand function of the permit by using the total allowable permit of the local government entity. The equilibrium price of the permit would be estimated to be $1,409.3won/kg{\cdot}BOD$. This is within reasonable boundary compared for the permit price compared to foreign example. This permit price would be applied to calculate for the economic value of the water quality pollutants, and also be expected to use directly for the B/C analysis of the business involved with water quality change.

Reincarnation, literally means "to be made flesh again". It is a mystical belief that the soul lives again in a new body after death. In this study, both material and spiritual elements are reincarnated in the form of the formative art in our life. This is similar to the notion of transmigration of the souls in Buddhism and Taoism. The concept "reincarnation"has a functional values as it provides a new tool in the education in the field. Especially in the digital design, the concept has become an essential contents as a text. The education employed the concept has a feature of edutainment which has been considered as an innovative method of education. The edutainment stimulates students' inner motivation and interests. This eventually leads them to use their own creativity in their study and achieve their goals. The education adopting the concept of reincarnation is more than the recycling of the used materials. It presupposes the understanding of the essence as well as the philosophical value of the materials. The creativity in the Visual Arts can be achieved with these educational foundations.

This study aims to discuss the concept of upcycling as it applies to diaper recycling. Upcycling is the process of converting waste materials into new products of better quality. Through benchmarking of upcycling examples, useless objects can be transformed into valuable materials. However, current upcycling examples determine value creation related to qualitative elements, so that it is difficult to establish any quantitative strategy of upcycled products. Therefore, this study expands a B2B (Business to business) product for improving market availability and establishes a direction using both recovered pulp and mixed plastic at the same time. As a result, the upcycling method for recovered pulp and mixed plastics, is the application of a cellulose insulator. Within the near future, the high quality insulator market will grow more than three times. An upcycling strategy targeting the high quality insulator market needs to be established.

우리나라에서는 어린이 설사, 위염을 치료하고 충치를 예방할 수 있는 달걀이 지난해말 개발되어 시중에 시판되고 있다. 이러한 기능성 계란은 한국식품개발연구원과 에그바이오텍, 시트리 등 바이오 업체 중심으로 개발되어 다한영농법인, 강남농장, 에그원, 가농바이오 등 농장에서 생산하여 소비자에게 공급하고 있다. 그러나 이러한 기능성계란은 인체용으로 사용되어 왔고 가축 질병 치료제로 사용되지는 못했다. ㈜단$\cdot$바이오텍(대표 김정우)은 첨단 생물공학기술을 이용하여 동물생체에 친화적인 고품질의 신생물질(면역항체, lgY)의 생산을 산업화함으로써 동물과 사람의 치료시 화학제제 및 항생제의 장기복용 및 오$\cdot$남용으로 인해 발생되는 제반 문제점을 해결한다는 사명감을 가지고 지난해 10월 출범하여 업계의 관심이 집중되고 있다.

SiC는 wide bandgap 물질로서 그 material properties로 인하여, high tmperature, high power, high frequency영역으로의 사용이 기대되는 물질이다. 따라서 SiC에 대한 기본적인 연구와 더불어, 그 소자 제작 및 응용에의 연구가 절실한 시점이다. 이에, SiC 기본적인 소자중 하나인 Schottky diode에 대해 연구하였다. 본 논문은 Schottky contact 물질로써 현재까지 연구가 미비한 Ru을 사용하였다. Ru은 Pt 계열물질로써, 다른 metal에 비하여 열역학적으로 안정하며, 또한 그의 산소 화합물인 RuO2는 다른 oxide에 비하여 전도성 이 높은 장점을 가지고 있다. 따라서 Ru-SiC diode는 이러한 측면에서 연구할 만한 가치가 있다.

The purpose of this study was to examine fashion counterfeit purchasing behavior among female college students.497 female college students living in Seoul were surveyed for this study. For data analysis, descriptive statistics, factor analysis, and t-test were used. As the results, approximately 54% of respondents had purchased fashion counterfeits before. Among fashion counterfeit products, handbag, apparels, shoes and accessories were frequently purchased by them. For materialism instrument, three factors of materialism were found and labeled as happiness, ownership, and economic factors. Three factors of shopping values were also identified as hedonic, utilitarian, and social shopping values. There were statistically significant differences between purchasing group and non-purchasing group in terms of materialism and shopping values; that is, those who had purchased fashion counterfeits showed higher scores on materialism and hedonic and social shopping value than those who had not.

This study proposed a model for estimating the unit value of social cost for mobile emission considering local geographical and social characteristics, together with a method to evaluate the air quality value. The model was built based on benefit transfer methods, the population density, and green space ratio of each area, which are reflected through independent variables. While applying the model, the unit value of social cost for mobile emissions in both densely populated areas of Seoul and Busan was found to be 18.68 times and 10.71 times higher than the national average, respectively. It is highly expected that this study can contribute to providing more reliable guidelines to decision makers when evaluating various green transportation policies and projects.

지금 사회는 물질중심에서 정신(문화)중심의 뉴 패러다임을 맞이하고 있다. 소득수준이 향상되면서 물질뿐만 아니라 국가의 전통문화, 민간 공예, 지방 전통 등 정신적인 측면이 강조되고 있다. 따라서 본 논문은 중국 전지요소를 활용한 포스터 광고 디자인을 통해 전지 요소로서의 활용 가능성을 확대하고, 중국 전통 전지공예의 가치를 재조명하는 동시에 중국 광고 포스터 디자인의 현지화 및 세계화에 대한 가능성을 연구해 보았다.
