Printmaking is a field of fine arts and is placed on a vague boundary that is perceived as a commercial product with a popular character due to the speciality of editions. Advances of modern science and technology has developed a new technique of printmaking, and the fusion of printmaking and computer has shown the possibility of reproduction art. Reproduction printmaking has been heavily influenced by photography and extended areas, and the various forms of printing have brought about many changes and attempts by stimulating the possibilities of indirect art at various angles. As the history of printmaking and technology closely relate, the development of computer makes widespread expansion of plural artistry, technological and artistic change. A new conceptual shape can be created on the copied image simply by placing the material of the print on the smoothly flat surface expressed in digital form. The process and the result of such work show the area of unique work which is different from the value of the $\grave{a}$ la carte art or the characteristics of the material given by the print. The deprecated perception of reproducibility evaluated the value of the work in a direct sense of printmaking. It is undeniable that it is devalued by a bundle of works regardless of the value of each edition. However, the physical properties of the prints on the paper are brought up with hand drawings drawn on the canvas by hand. And it becomes an opportunity to show new aspect and change through the process of combining digital print information on paper. The diversity of media is sometimes a controversy of identity between art and technology. In the future, it should be discussed how the limit of the media which can be enjoyed in the field of art can be set as a standard.

During the Joseon period, the East Sea would be called 'Gyeonghae' due to a large number of whales. In the Republic of Korea, whaling was locally permitted in 1946. However, the number drastically dropped because the hunting of the marine mammal had already been carried out in Russia, the U.S. and Japan since 1800s. Before a moratorium on commercial whaling was introduced by the International Whaling Commission(IWC) in 1986, whale populations in the East Sea had plunged. Furthermore, Korean gray whales and fin whales weren't found anymore in that area. With the suspension, whale hunting was banned in Korea as well. Even so, accidentally caught whales have been allowed to be distributed on the market with respect for local food culture. With the establishment of Whale Museum and hosting of the 57th Annual Meeting of the International Whaling Commission(IWC) at Jangsaengpo in 2005, whale tourism was facilitated in earnest. This whale tourism has been operated by Nam-gu Office and Nam-gu City Management Corporation in Ulsan. However, the popularity of whale tourism has increased a demand for whale meat. At the same time, there has been concern over decrease in whale populations because of illegal whaling. In addition, a conflict between the use and protection of whales has caused confusion in tourism identity. Actually, there is a serious doubt on the sustainability of whale tourism due to the decade-long deficit and excessive investments. This study attempts to define a concept of whale tourism and propose a future direction for the sustainable growth and development of Korea's whale tourism industry after developing such comprehensive assessment indicators as a basic research for the introduction of sustainable whale tourism. To achieve the aim of this study, AHP(Analytic Hierarchy Process) was chosen as a main research tool and the factors were ranked by a comprehensive analysis of principal factors and detail factors. The current study showed the following results. First, ecological environment(0.430) was indicated the most important factor of whale tourism assessment indicators. Moreover, Population(0.1302), Action for Cetacean protection(0.1031), Governance(0.0898) were critical factors. On the other hand, Accommodations(0.0085), Whale meat(0.0088) were unimportant factors than others.

The researchers, who seek geological and environmental information, depend on the remote sensing and aerial photographic datum from various commercial satellites and aircraft. However, the adverse weather conditions and the expensive equipment can restrict that the researcher can collect their data anywhere and any time. To allow for better flexibility, we have developed a compact, a multi-spectral automatic Aerial photographic system(PKNU 2). This system's Multi-spectral camera can catch the visible(RGB) and infrared(NIR) bands($3032{\times}2008$ pixels) image. Visible and infrared bands images were obtained from each camera respectively and produced Color-infrared composite images to be analyzed in the purpose of the environment monitor but that was not very good data. Moreover, it has a demerit that the stereoscopic overlap area is not satisfied with 60% due to the 12s storage time of each data, while it was possible that PKNU 2 system photographed photos of great capacity. Therefore, we have been developing the advanced PKNU 2(PKNU 3) that consists of color-infrared spectral camera can photograph the visible and near infrared bands data using one sensor at once, thermal infrared camera, two of 40 G computers to store images, and MPEG board to compress and transfer data to the computer at the real time and can attach and detach itself to a helicopter. Verification and calibration of each sensor(REDLAKE MS 4000, Raytheon IRPro) were conducted before we took the aerial photographs for obtaining more valuable data. Corrections for the spectral characteristics and radial lens distortions of sensor were carried out.

The results of the study were as follows : 1. Among the students under inquiry. $10.2\%$ answered they had the experience of smoking, while $6.3\%$ said they are current smokers. 2. With regard to smokers' smoking behavior. about 90% of them smoke one or two cigarettes a day. A lot of them was their own or friends' homes to smoke. but not at specific time. Many students who smoke say they was cigarettes stored and/or picked up at home. $28.9\%$ of them have friends who know that they smoke and $27.7\%$ of them have siblings are aware they are smokers. $24.2\%$ of them said no one around them is aware of the fact they. smoke. 3. Forth grade is the most frequent year students start smoking$(23.5\%)$. Most of them had their first smoking experience at their homes out of curiosity. 4. Profile of a typical smoker would; be male; from miscellaneous religions; have very few friends: have hard time to fit in at school and he/she has a poor academic record. 5. Environmental profile of a smoker consists of: commercial area resident: single-parented; lacks attention from parents; has hard time at home; has someone who smokes within the family. 6. Regarding the experience of smoking prevention education. the rate of current smokers who have learned about smoking prevention was lower than that of who have not learned. 7. Among the non-smoking students. $81.3\%$ of them said they would keep away from smoking and $1.6\%$ of them said they would like to smoke in the future. while $17.1\%$ were undecided. Among the students who smoke. $93.7\%$ wish to quit smoking.

The study examines the present condition and prospects of venture firm accumulation center in the case of kwan-ak venture town. The survey shows most of companies have been founded since 1997. Their major items are software development and the average employees are under 10 workers. According to the questionary about the type of R&D and the level of innovation, technology innovation such as the development of new product is advanced whereas tacit innovation like inter-firm cooperation is very weak. And the source of idea and information is concentrated on the within-firms and research center As a result of the analysis of regional linkage, the dependence of production and R & D is large on kwan-ak-gu, but sales and information services have emphasis on Seoul area. In the light of the affiliation of inter-firm, they response sympathy with cooperation, but could not strengthen their commercial ties yet. At last, the policy for venture firm accumulation center must intend to make tacit measures through inventing of system instead of the simple means such as the assistance of location, finance and tax.

A theme park is not just a recreational space for leisure activities, but also a place of storytelling as collected around abstract boundaries called themes. These stories are 'a space that tells the meaning' that the visitor is looking for and the Robot Land space offers robots, humans, and nature. This study is a description of the design strategy and content of the work which was elected as a subject of the subsequent rank negotiation of the Masan Robot Land design contest for the selection of a private contractor. The focus of the plan is, first, the organizational power of each space and the delivery power of a theme for the history of revisits, which might be considered depending on whether or not the theme park has been successful in the visitor's mind. Second, it is to actively use the potential of Masan, which is not only the key hub of the mechanical industry but also has beautiful coastal resources. First, they created a space that can flexibly react depending on the user's desire and the change of form, minimizing environmental damage by using a linear metabolism that can provide an amalgam of the elemental characteristics of robots, humans, and nature as motifs. They introduced a planting plan for the admissions square, an existing forest, slope, vacation spot, the inside of a complex, and Eco Island, etc. by utilizing symbolic meaning and adjusting to the spatial characteristics of each space. In addition, they sought a detailed space by setting up zones tailored to the use and character of the subject area, having exhibitions and education about robots, vacation facilities for lodgers, various recreational and commercial facilities, and space for utopian gardens as themes. They planned Masan Robot Land to be a true cultural space that creates mental richness on the basis of not only the economical effects but also local emotion.

This study reports a numerical analysis of the internal flow characteristics of the integrated urea-SCR muffler system with the various geometries of the multi-perforated tube which is set up between the muffler inlet and in front of SCR catalysts. The multi-perforated tube is generally used to disperse uniformly the urea-water solution spray and to make better use of the SCR catalyst, resulting in the increased $NO_x$ reduction and decreased ammonia slip. The effects of the multi-perforated tube orifice area ratios on the velocity distributions in front of the SCR catalyst, which is ultimately quantified as the uniformity index, were investigated for the optimal muffler system design. The steady flow model was applied by using a general-purpose commercial software package. The air at the room temperature was used as a working fluid, instead of the exhaust gas and urea-water solution spray mixture. From the analysis results, it was clarified that the multi-perforated tube geometry sensitively affected to the formation of the bulk swirling motion inside the plenum chamber set in front of the SCR catalyst and to the uniformity index of the velocity distribution produced at the inlet of the catalyst.

Objective: The aim of this study was to investigate whether anti-M$\ddot{u}$llerian hormone (AMH) levels could be predict ovarian poor/hyper response and IVF cycle outcome. Methods: Between May 2010 and January 2011, serum AMH levels were evaluated with retrospective analysis. Three hundred seventy infertile women undergoing 461 IVF cycles between the ages of 20 and 42 were studied. We defined the poor response as the number of oocytes retrieved was equal or less than 3, and the hyper response as more than 25 oocytes retrieved. Serum AMH was measured by commercial enzymelinked immunoassay. Results: The number of oocytes retrieved was more correlated with the serum AMH level (r=0.781, $p$ <0.01) than serum FSH (r=-0.412, $p$ <0.01). The cut-off value of serum AMH levels for poor response was 1.05 ng/mL (receiver operating characteristic [ROC] curves/area under the curve [AUC], $ROC_{AUC}$=0.85, sensitivity 74%, specificity 87%). Hyper response cut-off value was 3.55 ng/mL $ROC_{AUC}$=0.91, sensitivity 94%, specificity 81%). When the study group was divided according to the serum AMH levels (low: <1.05 ng/mL, middle: 1.05 ng/mL - 3.55 ng/mL, high: >3.55 ng/mL), the groups showed no statistical differences in mature oocyte rates (71.6% vs. 76.5% vs. 74.8%) or fertilization rates (76.9% vs. 76.6% vs. 73.8%), but showed significant differences in clinical pregnancy rates (21.7% vs. 24.1% vs. 40.8%, $p$=0.017). Conclusion: The serum AMH level can be used to predict the number of oocytes retrieved in patients, distinguishing poor and high responders.

As the supply of photovoltaic (PV) increases worldwide, the cumulative installations in 2018 were 7.9 and 560 GW in Korea and the world, respectively. Typically, when the ground on commercial PV modules is installed, the area is limited; hence, new designs of PV modules are required to install additional PVs. Among the new design of PV modules, lightweight PV modules can be utilized in PV systems, such as buildings, farmlands, and floating PV. Concerning the investigation of lightweight PV modules, several studies on materials for replacing low-iron tempered glass, which comprises approximately 65% of the PV module weight, have been conducted. However, materials that are used as substitutes for glass should possess similar lightweight properties and reliability as glass. In this study, experimental tests were performed to evaluate the applicability of ethylene tetrafluoroethylene (ETFE) film with excellent resistance to water and aging as a front material of PV modules. The transmittance and ultraviolet properties of the ETFE film were determined and compared with those of glass. A 1-cell module and laboratory-scale 24-cell module were manufactured using the ETFE film and glass, and the electrical output was measured and analyzed. Furthermore, damp heat and thermal cycle tests were conducted to evaluate the reliability of the ETFE film module. Based on the experimental results, the electrical output and reliability of the ETFE film module were similar to those of the glass module, and the ETFE film could be used as the front material of PV modules.

Six commercial ginseng products, red ginseng, white ginseng I and II, red ginseng extract, white ginseng extract I and II were extracted with ethyl ether. Total fatty acid composition of the extracted free lipids was analyzed by gas liquid chromatography and digital integrator was used to measure the area of each peak. Crude lipid contents of red and white ginsengs were similiar. Those of red ginseng extract, white ginseng extract I and II were 1.10, 1.13 and 0.40%, respectively. It was found that 22 kinds of fatty acids existed in red and white ginsengs. Among them, 16 kinds of even numbered fatty acids were identified. Linoleic acid in red and white ginsengs was the most abundant. The contents of that in red ginseng, white ginseng I and II were 63.33, 45.55 and 41.06%, respectively. The next most abundant acid was palmitic acid, the contents of which were 11.30, 14.4 and 18.10% for red ginseng, white ginseng I and II, respectively. Major fatty acids for red ginseng extract and white ginseng extract I were linoleic and palmitic acids in the same order of magnitude. Linoleic and palmitic acids for red ginseng extract were 15.93 and 15.71 %, respectively, while linoleic and palmitic acids for white ginseng extract I were 21.94 and 19.15%, respectively. However, white ginseng extract II contained only 9.21% of linoleic acid and 16.13% of palmitic acid which was the major fatty acid.
