  • 콩나물 재배에서의 살수방법과 그에 따른 콩나물 생육형태와 수율변화를 비교해본 결과 다음과 같다. 1. 살수방식에 따른 콩나물의 생육에 큰 차이를 나타내었으며, 왕복살수형, 용기담수형, 고정살수형 중 고정살수형 방식(재배통 상부에 하부타공된 고정형 물통설치에 의해 샤워형태로 살수)은 살수시 일시에 물을 샤워형식으로 쏟아내려 재배통 내부의 품온저하($22^{\circ}$ 유지), 내부 gas 배출, 유기물 제거 등의 효과가 탁월하여 콩나물 생육에 있어 몸통길이 13.3 cm로 다른 형식(15.2 cm, 15.9 cm)에 비해 짧았으나, 몸통두께(2.19 mm), 수율(535%)은 높게 나타나, 외관이 양호하고 부패가 억제되어 선도가 가장 잘 유지되었으며, 또한, 콩나물 재배시 필요한 용수량의 경우는 1회 살수량이 250∼300 L/통(원료콩 투입량 50 kg/통 기준)가 가장 양호한 것으로 나타났다. 2. 고정살수형 방식은 내부 gas($\textrm{CO}_2$ 5% 이하)배출이 탁월하여 재배완료 후 콩나물의 색택향상 및 부분부패 방지효과 등을 나타내는 장점이 있었으며, 재배 6일차에 재배통 하부(바닥깔판으로부터 약 30 cm이내)의 $\textrm{CO}_2$ 농도는 4-6%, $\textrm{O}_2$ 농도는 13-14%이었다. 따라서 재배시 재배통내 적정 gas조건은 농도 10% 이상, $\textrm{CO}_2$ 농도 5% 이하로 유지되어야 할 것으로 판단되었다. 3. 살수방식에 따른 재배통내의 품온 변화에서도 고정살수형 방식(4일차, $20^{\circ}$)이 용기담수형 방식(4일차, $22^{\circ}$)보다 품온 억제가 양호하여 콩나물의 생육향상 및 부패 등을 방지하므로 건강한 콩나물 생산의 중요한 요인임을 알 수 있었다.되지 않은 부분에 대해서 안전성 확보를 위하여 더 자세한 연구가 필요하다..6%이었다.program should be prepared through the long-period of monitoring and experiment.

However, most of the cigarette companies self impose a list of ingredients to guide flavor suppliers to design flavors. Unfortunately, the number of ingredients in those lists is getting shorter every year. It is understandable that the health is not the only reason. Some cigarette companies are playing safe to protect the company from potential lawsuit, while others are just copying from their competitors. Moreover, it is obvious that it needs more assistance from casings and

  • Since WWII and the Korean War, Korean modern fashion has been americanized by claiming, displacing with, and fusing with the traits of American fashion. The purpose of this study is to observe and analyze the traits of Americanization in Korean fashion, focusing on the designs of Nora Noh fashion from the 1950s to the 1980s. Nora Noh (1928- ), one of the first Korean fashion designers, who launched the first fashion show in 1956, introduced ready-made dresses to Korean fashion industry in 1963 for the first time, and later in the 1970s and the 1980s, exported Korean-made fashions to the U.S. market. For such purpose, this study first provides the theoretical backgrounds of Americanization in Korean fashion history and then conducts a case study by analyzing photographic materials. In case of Nora Noh fashion, the traits of Americanization can be defined as functionality, popularity, and hybrid. (1)Functionality in Americanized Korean fashion was expressed through simplicity, practicality, and usefulness. Noh's "homewear" style and exported silk dresses are the examples of the functionality. (2)Popularity was shown in kitsch images of materialistic and consumer culture. It was expressed in ready-made dresses and trendy styles of mini skrits and bell-bottom pants. (3)Hybrids of various multi-culture exist in American culture and fashion. In Noh's designs, traditional materials and the print patterns inspired from traditional motifs were used to add Korean nuances in Americanized fashion.

  • Objectives : The anticancer response of three different types of water extracts of Zingiberaceae Curcuma longa L. tested for sarcoma 180. Only few studies carried out to investigate the effects of other contents of Curcuma longa L. in anticancer activities, therefore, in this study we have investigated the effects of other component then curcumin in Curcuma longa L. for anticancer a activities. Methods : Three different types of water extracts of Curcuma longa L. were prepared as follows. The sarcoma cells (S180) were maintained in Dulbecco's modified Eagle's medium (DMEM) and were seeded on 24-well cell culture cluster flat bottom with lid tissue culture treated non-pyrogenic polystyrene. The growth of sarcoma 180 was monitored for 1, 2 and 5 days. The sarcoma cells were pictured using inverted microscope and cell density was counted using hemocytometry. Results : After 5 days in the culture medium the results showed high growth of sarcoma 180 for control condition and the surface of CCP plates were fully covered with the cells. In case of medium in which the 10% of filtered water extract of Curcuma longa L. was added a very limited growth of sarcoma 180 was observed. The results were showed only small difference in cell density for two different concentrations of unfiltered water extracts of Curcuma longa L. whereasin case of filtered water extracts the control of sarcoma growth shows better result. Conclusion : The filtered water extracts showed the best result relatively to the unfiltered water extracts for two different concentrations. This indicates that the water extracts of Curcuma longa L. can have anticancer activities possibly without curcumin.

  • When analyzing forms in the human body and clothes, we conceptualize each part into a cone, sphere, and cylinder, and the esthetic characteristics of our fashion culture and esthetic fashion characteristics of Koreans are composed by expressing with universal images such as circle, square, and triangle when forms are expressed in a plane. To determine how the structural principle of shapes that are the shapes of all things and basic to geometry, i.e., circle, square, and triangle, applies to clothes that cloth our body called the small cosmos, we discussed the symbolic meaning hidden inside the structure of Korean clothes based on the basic pattern drafting method of Korean men’s traditional trousers. We drew the conclusion that Korean men's trousers composed of circles, triangles, and squares express the five elements diagram through their plane structure, are designed in circles with cones and pyramids, and are made to well express the principle of the small cosmos of our body. Moreover, when the basic pattern of Korean men’s trousers explained with the antipathy diagram is viewed to create all things while maintaining opposite and complementary relationship with Sangsang (mutually benefitting factor), it would be correct to say that the principle of the top verse the bottom is viewed as conflicting. From the structural point of view, since the philosophy of the Samsu principle (the principle of 1, 2 and 3 in which 1 represents the heaven, 2 represents the earth, and 3 represents the people) is hidden in Korean men's trousers in which Hurimalgi (the part of trousers corresponding to the waist band of Western pants) is the circle representing the heaven, Marupok is the square representing the earth, and Sapok is the triangle representing the people, we could look at deep meaning of our ancestors expressed in our clothes.

  • Jongga means a head family by only first son's line of each generation. It is our culture's root and identity. It also includes ritual for continuing filial duty. Ritual takes the main role on jongga culture to pay respects to Jongga's ancestors and roots. Therefore, ritual costume's importance can not be neglected. We will check a Po mainly for Jongga ritual costumes' types and designs to refind Jonggas identity and its meaning. In this research, areas are divided to Gyoungsang by Youngnam sect and Jeonla by Kiho sect. Geochang, Andong in Gyoungsang province and Haenam, Namwon, Youngkwang in Jeonla province where currently first sons of Jongga reside have been researched. The method is based on Books and visits on the places. Ritual costumes' types and designs are different between Gyoungsang and Jeonla. Firstly, now in Jongga, only a Dopo and a Durumagi are worn while the manner book shows a Danryoung, a Jikryoung, a Dopo and a Simu. Also costumes are variable on areas. Secondly, a Po is characterized by its sleeve and back-line's inside skirt. In a Po, Gyoungsang has a Duri sleeve and Jeonla has a Duri sleeve which has been changed from a Dunggun sleeve. While Gyoungsang has rectangle-shaped two pieces cloths and a split in a bottom, Jeonla has both a Mu with a split back and a complete split back in back-line's inside skirt. It seems that Youngnam sect's fundamentalism and Kiho sect's flexibility about culture of old political groups would have influenced on these patterns.

  • Monitoring for moisture contents of wooden post member of Un-bong confucian school was performed in 6 months and analyzed to conserve scientifically the wooden culture building and open for common people. In inner post member of the building, variation of moisture contents was very small and upper part had relatively higher moisture contents. In outer post member, moisture contents were changed according to the weather conditions and was relatively high in bottom and upper part. Southern post has lower moisture content than eastern. These results were related to air ventilation in interior, depth of eaves and orientation of the building. In the design, construction and maintenance of wooden building, characteristics of wood should be considered like moisture contents.

  • This study identifies how management theory and philosophy work in conjunction with and support one another as both are critical to understanding leadership concepts and viewing the design organization holistically in terms of organizational behavior and performance. This paper analyses data from an in-depth single-case study at management in interior design organization in Korea. Two new 'most efficient and effective way' to achieve the goals of the design organization has been launched. The first was organizational behavior and performance, and the second a needed new paradigm of management skills. Organizational culture affects organizational effectiveness in design because it can (a) provide an organization with a competitive advantage, (b) improve the way an organizational structure works, and (c) increase the motivation of designers to pursue organizational interests. Moreover, the result of research creates paradigm of thinking that how leaders in the design organization need to focus on innovative and strategic systems to gain competitive advantage and enter global markets; a key inter-organizational cooperation strategy to achieve a targeted goal.

  • Biodegradation of toluene in liquid effluent stream was carried out using biofilms of Pseudomonas putida formed on celite particles in the bubble column bioreactor. Silicon rubber tubing was installed at the bottom of the bioreactor and liquid toluene was circulated within the tubing. Toluene diffused out of the tube wall and was transferred into the culture broth where degradation by biofilms occurred. The operating variables affecting the formation of biofihns on celite particles were investigated in the bubble column bioreactor, and it was found that formation of bifilm is favored by high dilution rate and supply rate of carbon source which stimulate the growth of initially attached cells. Continuous biodegradation of toluene using biofilms was stablely conducted in the bioreactor for more than one month without any significant fluctuation, showing a removal efficiency higher than 95% at the toluene transfer rate of 1.2 g/L/h.
