  • This study was carried out to investigate the difference of the content of soil chemical components and growth characteristics in five years old ginseng affected by application of manure in paddy-converted field. As all livestock manure regardless of kinds increased along with the whole soil chemical component, including the pH and EC in 2008. Change in the EC of control plot was slightly increased but not exceeded 1 ds/m over the years. However, the changes in the EC of livestock manure regardless of kinds and amounts were highly increased and irregularly exceeded 1.5 ds/m in 2012. The 5 years old ginseng root fresh weight, treatment of fertilizing pig manure compost 4 ton per 10 areas (PMC 4t on/10a) and fowl manure compost 4 ton per 10 areas (FMC 4 ton/10a), were superior to the others. But there were no difference between PMC 4 ton/10a, FMC 4 ton/10a and control. The standing crop rate 39.6%, treatment of fertilizing cattle manure compost 4 ton per 10 areas (CMC 4 ton/10a), was best in all livestock manure. However that was relatively lower than control. Physiological disorder occurrence rates of livestock manure related with leaf and root of ginseng were also higher than that of control. If excessively using non-decomposed livestock manure, It would be caused physiological disorder in many ways. It is a big problem to be producing the quality ginseng. More research is needed to find out the economic and effective fertilizer.

  • 피트모스+버미큘라이트(5:5, A), 피트모스+펄라이트(7:3, B), 코코피트+펄라이트(7:3, C), 코코피트+피트모스+펄라이트(3.5:3.5:3.0, D), 왕겨+코코피트+펄라이트(2:7:1, E), 그리고 왕겨+코코피트(3:7, F)의 6종류 상토를 혼합하여 상부 직경 10cm의 플라스틱 포트에 충전한 후 '설향' 딸기의 모주에서 발생한 런너를 고정시켜 번식시키면서 상토 물리 화학성이 자묘 생육에 미치는 영향을 구명하기 위하여 본 연구를 수행하였다. 자묘 육묘용 상토의 용기용수량과 기상률은 상토별 차이가 뚜렷하였으며 E와 F 상토는 용기용수량이 낮고 기상률이 높아 상토의 수분관리에 어려움이 있을 것으로 판단하였다. 피트모스가 혼합된 상토 A, B, 및 D의 질소농도가 높았고, 왕겨를 혼합한 상토 E와 F의 질소 및 인산 농도가 낮았다. 또한 코코피트가 혼합된 상토가 피트모스가 혼합된 상토 보다 K 농도가 월등히 높았다. A상토에서 '설향' 자묘를 재배한 결과 약 13mm에서 관부직경의 회귀선이 형성되어 가장 굵었고, F, B와 C 상토에서 육묘한 자묘도 관부 직경의 회귀선이 약 10mm 이상에서 형성되고 있어 자묘의 생육에 바람직하다고 판단하였다. '설향' 자묘의 생체중은 A 상토에서 육묘한 경우 식물체당 10g 후반에서 회귀선이 형성되었지만, C, F, D, E, 그리고 B 상토의 순으로 가벼워졌다. '설향' 자묘의 건물중도 생체중과 유사한 경향을 보였으며 A, C 및 F 상토에서 비교적 건물중 생산량이 많았고, B 상토에서 적었다. 생체중과 건물중 생산량이 많을 경우 보편적으로 식물이 건전한 생육을 하고 있음을 의미하며, 이러한 판단을 적용할 때 A, C 및 F 상토가 자묘생육을 위해 바람직하다고 판단하였다.

  • 도로공사 후 발생되는 절개지 암사면의 토양 침시방지와 조기 식생도입을 위하여 시공되는 인공배양토가 산성 지하수에 노출되었을 때 나타나는 perennial ryegrass의 생육저해 원인을 조사하였다. Perennial ryegrass가 정상적으로 자라는 지역과 피해가 발생한 지역에서 각각 채취한 인공배양토의 화확적 특성과 인공배양토 추출물들에 대한 라이그래스 생육반응에는 현저한 차이가 없었다. 그러나 인공배양토를 시공한 후 피해가 발생한 지역의 배경토양은 정상지역의 배경토양에 비해 pH가 매우 낮고(pH 3.6), 추출성 철과 알루미늄의 함량이 현저하게 높았으며, 피해지역에서 채취한 토양의 물 추출물에 대한 라이그래스의 발아 및 뿌리 생육은 심한 저해 현상을 보였다. 피해지역에서 채취한 인공배양토와 배경토양에 대한 X-ray 분석결과 각각의 시료에서 jaroslte가 발견되었으며, 이는 라이그래스 생육저해의 원인이 피해지역 인근에서 용출되는 pyrite를 함유하는 산성지하수(pH 3.3)에 기인함을 암시한다. $Al^{3+}$$Fe^{2+}$, $Fe^{3+}$ 표준용액을 이용하여 라이그래스의 뿌리생장율을 50% 수준까지 감소시키는 $EC_{50}$값을 조사한 결과, 산성지하수와 유사한 pH 환경(pH 3.3)에서 라이그래스에 대한 $Al^{3+}$$Fe^{2+}$, $Fe^{3+}$$EC_{50}$값은 자각 0.5, 0.3, 19 mM 이었다. 이러한 결과는 산성 환경하에서는 매우 낮은 $Al^{3+}$$Fe^{2+}$ 농도수준에서 조차 라이그래스의 생장이 현저히 억제될 수 있으며, 산성지하수에 포함된 pyrite에 기인하는 낮은 pH, $Al^{3+}$$Fe^{2+}$ 이온용액이 라이그래스 생장저해의 직접적인 원인임을 의미한다.

  • Sustainability has been a big issue over the whole global industry lately and is an important fashion trend that reflects the modern phase of the time. The concept of sustainable fashion includes physical fashion products made from eco-friendly or recycle materials as well as ethical value such as corporate social responsibility for environment, labor or working condition. Fashion companies of advanced countries who are aware of the geo-environmental and ethical issues found that generating profits by setting trends and pursuing external beauty can no longer be the ultimate goal of fashion companies, and started to recognize the importance of sustainable fashion as a future-oriented trend. Not only fashion industry but also governments of advanced countries have been playing a leading role to educate the people regarding the importance of sustainable fashion and making large investments to foster industry specialists in educational institution. The aim of this study is to propose sustainable fashion design education program that fits the domestic university curriculum and government-leading education program in order to set the foundation for sustainable fashion industry. Thus, this study investigates successful cases of foreign government-led sustainable fashion education that can be introduced to improve domestic sustainable fashion education. The empirical study of the research is developing 12-15 week university level education program to foster specialists in sustainable fashion. The survey carried out by the students who participated in the program shows the change of perception on sustainable fashion. Developed university level program can be spread to municipal corporation, school of continuing education, and etc. in order to derive participation and problem perception of the citizens on sustainability. Developing systemized sustainable fashion design education program would be the first step of sustainable fashion by educating students who will take the leading role in the future fashion industry. Moreover, it can strongly influence future customer education as well as a special education inducing interest on sustainability in everyday life. A follow-up study is expected to serve as a foundation for sustainable fashion to take root successfully in the fashion industry.

  • The purpose of this study is to search the spiritual root of decoration and anti-decoration culture in contemporary Japanese fashion and find the aesthetic meanings of the decoration culture inside contemporary Japanese fashion. The contents of this study are 1. surveying the historical change about the aesthetic sense of Japan. decoration culture 2. deducing the distinctive aesthetic ideology from the decoration culture 3. finding esthetically the inside meaning of 1.2. in contemporary Japanese fashion. First, the origin of decoration culture was concerned with the belief in the life after death of the Buddhism culture to represent the noble society of the Heian(평안) period and the religion of paradise after the Middle Ages. Second. this decoration culture based on two aesthetic ideologies, beautiful(염) aesthetics and lofty(숭고) aesthetics. The beautiful aesthetics implies words, such as bewitchment, elegance, dignity and brilliance which stand for the sensual pleasure and the eroticism. The lofty aesthetics that was introduced by TakeTakasi(장고) during the Heian period, had the meaning of magnificence, greatness and dignity. This could be recognized as the Confucianism ideas. Third, as the beautiful aesthetics that was the representative aesthetic ideology of the decoration culture, it was related to splendid and decorative designs, and was recognized as the beauty of brilliance and coquetry. The beauty of brilliance, as a decorative element, appeared in patterns of the traditional costume and dyeing as well as the beauty of coquetry indicated that the women's fashion in Japan had soft, feminine, and cute images, called Hawaii, by using various decorations, such as feminine details, flower patterns. ruffles. ribbons and so on. TakeTakasi's lofty aesthetics applied the beauty of exaggeration to every art form. It has influenced the form exaggeration by overlapping in traditional costumes as well as the 1970s big look and layered look in Europe fashion. Issey Miyake and Takeda Kenzo introduced the decorative play, such as transformation and a distortion, which considered refinement, bluff, and oddity of the Japanese decoration art.

  • The root of cultural and artistic diversity of modern society goes hand in hand with the appearance of new art concepts that started during the social and cultural turmoil. These concepts crossed the boundaries of traditional and universal aesthetic concepts and value criteria. Since there is a close relationship between the fashion industry and the cultural flow of its times, the purpose of this study is to investigate the influences and applications of conceptual art, which became one of the big frameworks of contemporary art on fashion. The study thus sets out to develop and analyze the collections of Hussein Chalayan and Martin Margiela, who were fashion designers that pursued conceptual and ideal values, from the perspective of conceptual art. The goal was to examine the conceptual thoughts they sought after, and to understand their expressive determinations that they pursued conceptually as well as the superficial formativeness of their works. The characteristics according to the expressive methods and conceptual intentions of conceptual art that specified concepts and ideas were as follows: readymade symbolized objects, expanded intervention, data form from process of changing and implementation, and language as visual metaphors. Then those characteristics of conceptual art were used in this study to analyze the collections of Chalayan and Margiela. As a result, both designers applied and mixed many characteristics of the expressive methods of conceptual art. In modern society, art and fashion share a cultural identity and it can be said that it is an accurate reflection of the time. They are not separate genres. Just like the unique flow of modern society that creates new concepts through mixture and infusion of different disciplines, fashion is included in the domain of art. In addition, understanding and studying other disciplines can make a huge contribution to the growth and development of fashion.

  • In South Korea, agricultural mechanization has been carried out in paddy field, but not in the upland field during recent decades. Among crops such as root vegetables, leafy vegetables from upland field, corn is used as forage for livestock as well as food for men. The corn harvester needs to be developed to replace men's labor in rural area to follow the recent needs in the farm industry. The corn harvester is comprised of three parts such as cutting part, feeding part and pick-up part. The feeding part is so long for cut corns to be delivered from the cutting part to the pick-up part. Structurally, the load from the long moment arm is likely to be big. Thus, the setup to measure the stress on the duct of the feeding part was configured with the data acquisition system. The strain gages were attached on several points that seem to be loaded a lot comparatively. The stress was measured and the measured stresses were divided by the yield stress to get the safety factor. And then, we made sure the safety factors were above 1 on the all points. In conclusion, the feeding part of the corn harvester which convey the cut corn from the cutting part from the pick-up part can be regarded to be made safe structurally.

  • Objectives : A morphological classification among Achyranthes japonica Nakai (produced in Korea), A. bidentata Blume (imported from China), and Cyathula officinalis Kuan (used in China exclusively) was made through microscopic observation. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Result : 1. Korean A. japonica Nakai has slim roots, whose diameter is $1{\sim}5\;mm$. 1) Most of its intersection is stele, which includes a lot of vascular bundles. The inside of vascular bundles shows the arrangement of $2{\sim}4$ cycles, the innermost wheel of which is divided into two parts. 2) Parts of parenchymatous cell include Crystal sand of calcium oxalate. 2. The diameter of the roots of Chinese A. bidentata Blume is $0.4{\sim}1\;cm$. 1) The xylem in the vascular bundle in the middle of its intersection is rather big, around which the inner parts of the vascular bundles are arranged in the shape of $2{\sim}4$ cycles around. The most outside part of it is small, and the middle part is gathered into $2{\sim}3$ groups. 2) Parts of parenchymatous cells include Crystal sand of calcium oxalate. 3. The roots of Chinese C. officinalis Kuan is thick, whose diameter is $0.5{\sim}3\;cm$. 1) Vascular bundle of its intersection is spotted, arranged in the shape of $4{\sim}11$ concentric circles, whose center is divided into $2{\sim}9$ groups. 2) Parenchymatous cells include crystal sand and square crystal of calcium oxalate. Conclusion : It is concluded that Achyranthes japonica Nakai, A. bidentata Blume, and C. officinalis Kuan have different shapes in both external forms and internal intersections, so that they can be easily distinguished from one another through microscopic observation.

  • 최근 이슈가 되고 있는 '빅 데이터'의 사회적 잠재성을 정부의 대국민 서비스와 연계지어, 정부의 행정서비스 혁신에 빅데이터의 사상이 기여할 수 있는 구체적 방안을 모색하였다. 특히 주민 생활공간과 정부 업무공간의 이원화가 초래한 정부 행정서비스의 본원적 한계를 행정 프로세스의 외부 확장을 통해 극복할 수 있는 방안을 제시하였다. 또한 이로부터 제기될 수밖에 없는 선결과제, 즉 주민 공간의 각종 사물데이터를 어떻게 행정 데이터 영역에 편입할 것인가에 대한 논의를 포함하였다. 이로써 행정서비스 영역에 대한 빅데이터 기반 조성이 신고와 신청에 의존하던 수동적 행정서비스를 선제적으로 바꿔내는데 어떤 역할을 할 수 있는지에 대한 시사점을 제시하였다.
