With the new millennium setting in, our society is plowing its way through more drastically changing currents than ever. Nowadays, many people believe that high tech such as the Internet, digital civilization, the IT revolution, bio-industry, and the genome project, that has brought humans material prosperity, is the right change in direction. However, the more we adopt high tech into our lives, the more we desire high touch in order to achieve a balance. In other words, we need something to act as a ballast to stabilize our minds. As such, the more high tech develops, the more individuals miss and search for tools that appeal to their emotions. Because of this, although high touch is an opposite concept to high tech, it coexists with high tech, and it is defined as "human contact of high sensitivity that stimulates the emotion of humans". High Touch, a term which originated from "High Tech, High Touch", a book written by American futurist John Naisbitt, refers to human contact that makes human life richer, forminga deep impression on individuals and providing comfort. As such, high touch, which is gaining significant attention in modern society, is a phenomenon occurring throughout politics, society, culture, art, and religion, together with high tech. Through high touch, modern people must realize how to understand and accept a modern society that is dominated by the age of technology and in which direction they should head. Under this background, this study has the following objectives: to interpret the concept of high touch in the age of high tech in association with formative art and fashion, and through various media examine the desire for expression that may stimulate emotion in modern people, which is required by the high tech-prevalent modern society. It further analyzes how high touch is reflected in modern fashion and presents the direction future fashion should head in.

Interspecific hybridization is a beneficial strategy in aquaculture. In this study, diploid hybrids were produced through interspecies hybridization of flounder Platichthys bicoloratus ♀ × starry flounder P. stellatus ♂, which became commercial within a year. These hybrids exhibited an advantage in growth ability, with female hybrids growing twice as large as males at 11 months. Furthermore, hybrid flounders exhibited faster growth rates than starry flounders and reciprocal hybrids. The average growth rate of hybrids was 1.37 and 1.18 times greater than that of starry flounder and reciprocal hybrids at 5.5 months, respectively; Additionally, feed efficiency was 1.21 and 1.10 times higher than that of the experimental groups. The experiments were conducted at five temperatures to determine the optimal fry production method. Six weeks of culture resulted in a significant temperature effect, with maximum growth at 27℃. However, over 90% of the males occurred in the groups at temperatures above 24℃. Therefore, the optimum temperatures for survival, growth, condition factor and frequency of the best-sized fingerling at 13 weeks of age were estimated at 21℃. Thus, hybrid flounders are of great potential for use in the flounder aquaculture industry.

The fluid power products are widely used in current industrial area such as automation of products and equipment assembly, high-tech machine tool, aircraft, train, and etc. As the development of industry is in progress, the development of the fluid power products is demanding and it is required in every industrial area. This research proposed a pneumatic system to evaluate displacement accuracy of the pneumatic actuator without external load and to analyze capability of integration of the valve system. The pneumatic system consisted of a combination of pneumatic actuator, four two-port valves, two three-port valves, two pressure valve, a check valve, two proximity sensors, and a program logic controller (PLC). The position controller is based on the PLC connected with the proximity sensors. The maximum air pressure applied for tests was $49.05N/cm^2$ and the displacement accuracy of a stroke was measured using a dial gauge. The supply- and discharge-side of air pressure and the length of the stroke of the pneumatic cylinder were varied The test of the position control of the pneumatic cylinder was carried out 50 times at each supply- and discharge-side air pressure of 24.53/34.34, 29.43/39.24, 34.34/44.15, and $39.24/49.05N/cm^2$ and replicated three times. The accuracy of the displacement of the pneumatic cylinder stroke increased as the supply- and discharge-side of air pressure increased with the stroke length of 133mm. Also the displacement accuracy increased as the stroke length increased with the fixed supply- and discharge-side of air pressure of the pneumatic cylinder as 34.34 and $44.15N/cm^2$, respectively. The most accurate displacement of the pneumatic cylinder was obtained at the supplyand discharge-side of air pressure of 39.24 and $49.05N/cm^2$, respectively, and strokes of 170 and 190mm.

기능성 화장품이라 함은 피부미백, 주름개선, 자외선차단 등 특정한 기능을 가지고 피부에 효과를 주는 화장품을 말했다. 그런데 2017년 이후 기능성 화장품의 품목이 확대되었다. 대한민국의 기능성 화장품 산업은 미백, 주름, 자외선 차단 제품에 머물고 새로운 기능성 제품의 개발은 미비한 상태이다. 또한 코스메슈티컬과 메디컬 화장품을 비롯한 고기능성 화장품도 아직 정립되지 않은 상태이다. 그리고 국외에 수출실적 순위는 프랑스가 가장 높았고 미국, 독일 순으로 나타났다. 프랑스는 화장품 산업 업계 1위 국가답게 바이오 공업과 기능성 소재에서 메커니즘 중심의 기능성 화장품을 강조하고 있고 미국은 럭셔리 프리미엄 제품에 수요도가 높았으며 독일은 바이오 하이테크 기술에 주목하고 있다. 이처럼 한국도 신흥 산업에 적용할 수 있는 기능성 화장품들의 새로운 소재들을 개발하고 정치와 경제가 뒷받침 되어 연구에 더 집중할 수 있는 환경이 갖춰져 다양한 기능성 화장품 산업 등을 발전시켜 나아가야 할 것이다.

The seed paper was used in farm field recently for a sound young plant. The most of seed paper are made of synthetic non-woven sheet. Therefore, it is very difficult to bio-degrade in soil and is very hard to have some special function, for example keeping herbicide and/or insecticide activity because of its lack of chemical acceptability. The purpose of this research is manufacture of seedling paper which have a function of herbicide activity from waste paper. The fiber properties from waste paper were remarkably improved by fine removal with washing and/or flotation process. The paper-making ability for seed paper was enhanced with enzyme treatment of secondary fibers. The paper for seedling must have a good bio-degradation ability in soils. The absorption amount of chemical like as dithiopyr was increased remarkably in enzyme treated base paper. The embossing treatment of base paper was very effective for seed attachment and chemicals retention. And also, the developed seed paper showed a good penetration property of young root through embossed paper.

The purpose of this study is to suggest the direction for the development of intelligent agricultural machinery technology in the Republic of Korea. For this purpose, intelligent technology of agricultural machinery was divided into autonomous agricultural machinery and tractor-implement intelligent communication technology. Then, a survey and analysis of a previous study of the Republic of Korea and foreign countries were conducted. GNSS-based autonomous driving technology is still widely used worldwide, and recently, as research on camera and LiDAR-based autonomous driving is actively progressing, autonomous driving technology is becoming more advanced. ISOBUS-based technology is being developed worldwide for intelligent control of tractor-attached implements, and major global agricultural machinery manufacturers are actively applying it to their products. However, although some ISOBUS technologies are being researched in the Republic of Korea, there are no cases of application on agricultural machinery yet. Therefore, to be globally competitive in the agricultural machinery manufacturing industry, there is an urgent need to advance autonomous driving technology and commercialize agricultural machinery using ISOBUS technology.

DNA extracted from ancient bones of Cervidae animals was examined to identify the species and to determine the phylogenetic relationships to those from extant cervids. Abundant ancient bones were excavated from Kumsung archaeological site in Jeju Island, Korea, and were identified as Cervidae animals based on morphological features of their antlers and lower mandibles. Their mitochondrial DNA (mtDNA) control region (CR) was partially sequenced and subsequently compared with those previously reported in database. The results confirmed that the ancient sequences are lineage of Cervidae. On the phylogenetic trees constructed using the sequence diversity of the CR sequences of family Cervidae, the ancient DNA sequences were found on distinct clusters. The ancient sequences were located in the subfamily Capreolinae cluster, and six ancient sequences were closely related to those of extant Korean roe deer in Jeju Island and Korean Peninsula. Consequently, the results of this study suggest that the roe deer inhabited Jeju Island in ancient times. However, there is no evidence for the existence of subfamily Cervinae, including Sika deer, while it has been described in several historical records. The results suggest that this finding could contribute to understanding of the origin and phylogenetic relationships of extant and ancient roe deer on Jeju Island.
