The acknowledgement of the environmental ceramic arts is the starting point in establishing the environmental ceramic rts as one separate genre. This study has investigated several items for the development of environmental ceramic arts as follows; First, the methods for building up conceptions were studied. Second, it has investigated when and how Korean environmental ceramic arts had developed. Third, establishing methods and ways of it were studied. Fourth, by showing several practical examples, the methods for application of ancient classics were explained. The results from these investigations, Korean ancient classics of environmental ceramic arts are not started these days, but has accumulation of 1000 years experiences. So, I could try to define new environmental ceramic arts thanks to ancient classics which have profound background, free and progressive way of thinking. By the result of these, in this research, by introducing the definition of ancient classical environmental ceramic arts to modern ones, we can try to search the ways of linking ancient classics and the future.

This study was conducted to investigate the effects of extrusion pressure and particle size of feed ingredients on the growth performance and plasma hormone activity in juvenile olive flounder Paralichthys olivaceus. Experimental diets were prepared with extrusion pressure manipulated by screw speed [low pressure (LP), 885 rpm/min; high pressure (HP), 708 rpm/min] and different dietary particle sizes [specific surface area: small (SS), 169.9 m2/kg; large (LS), 67.4 m2/kg] in a two-level factorial design. Four experimental diets (LP+SS, LP+LS, HP+SS, and HP+LS) were randomly assigned to 12 tanks (3 replicates) stocked with 20 fish (initial weight, 57 g) per tank. After a 4-week feeding trial, the observable trends of the main effects of extrusion pressure and particle size on growth performance showed that LP and SS enhanced fish weight gain. The plasma insulin-like growth factor-I level was significantly higher in fish fed the LP+SS diet than in fish fed the HP+SS diet. These results indicate that manipulation of the physical qualities of feed through adjustment of extrusion pressure and feed ingredient particle size may influence the growth performance of juvenile olive flounder, which should be considered in feed manufacture.

코하우징 계획을 위한 주민참여 워크숍 사례 - 30~40대 주부를 대상으로 -

Resident participation plays much of a rule to the cohousing, which is organized independently and has the characteristics of community life, especially in the initial state of cohousing process. However, it is hard to realize the resident participation in proper order due to lack of a personal time, individual effort and an insufficient knowledge related with cohousing. So, it is thought that the guidance of cohousing expert and coordinator is needed to enable the residents to perform in an active attitude. The development of educational program and workshop connected with resident participation is also accompanied. In this study, to make the positive and systematic participation of cohousing residents, we established the workshop program and performed workshop with our developed program, based on preceding researches and examples. We selected the object of workshop as five housewives in thirties and forties. Workshop was consisted of six process steps. (1) Introduction and question of workshop and cohousing (2) examining and arranging the opinion (3) Master plan of cohousing village (4) Planning of common living space (5) Planning of individual living space (6) Analysis of final results and evaluation of workshop. The workshop held six times and it took about five~six hours per each meeting. Workshop participants expressed their opinion actively and attended in a positive manner in order to the design of their desired village and cohousing. During workshop process, the players established the common target of their village by means of life card, target card game. Also, based on the common target, the layout of village was planned using a collage game and card arrangement game. By workshop activity, the members started to recognize the significance of participation on the drawing board and improve their technique of communication and decision-making. Furthermore, workshop process made it possible to approach the concrete forms of their cohousing village. Especially, in the closing phase, the participant satisfaction about workshop and cohousing is increased suddenly and expressed their intention to join the real workshop related with cohousing.

The approach for supporting synchronous Ethernet in 10G EPON

조정현,안철웅,장용석 한국산업정보학회 2013 한국산업정보학회논문지 Vol.18 No.6

In recent, many countries and research institutes have been studying how to construct the high-speed subscriber access network. Task Force team of IEEE 802.3ah has accomplished the standardization of EPON which is the next generation subscriber access network. EPON doesn’t still have the bandwidth enough to support the new service(e.g various multimedia service) which demands the high bandwidth. For these new multimedia services,10G EPON is the next generation subscriber access network which expanded the up-down bandwidth range of 1G EPON 10 times in order to support demanding high bandwidth. We have proposed the model which can accommodate IEEE 802.1 AVB traffics smoothly in 10G EPON and suggesting the Intra-ONU scheduling model which makes this model operate effectively.

It is observed the characteristic of the microwave air plasma in the wide range of the operating pressure, 1 mTorr ~ 760 Torr. The microwave air plasma was generated by an AC-type microwave source manufactured with a magnetron taken from a commertial microwave oven and the input power was fixed at 370 W. Characteristics of the plasmas were observed by an injection Langmuir probe and an OES(Optical Emission Spectroscopy). The breakdown electric field is drastically changed at 500 mTorr. For < 500 mTorr, the ratio of the breakdown electric field and the pressure decreased inversely to the pressure, $5.7\times10^4$V/m-Torr.However, the ratio increased linearly as 43 V/m-Torr for the operating pressure, > 500 mTorr. The minimum breakdown electric field was observed about 12. kV/m at 500 mTorr. It corresponds that the input frequency equals to the collision frequency. The effective collision cross section of the air at this pressure was calculated as $9.23\times10^{-l6}\textrm{cm}^2$.The results of the OES measurement revealed that the main ions were composed of the oxygen, argon, and nitrogen for > 500 mTorr. In contrast, only oxygen and argon ions were dominated for < 500 mTorr. ion temperature of oxygen (O(II)) in the air was decreased from about 1.2 eV to 0.5 eV as the pressure increased. Langmuir probe data shows that the plasma density for < 500 mTorr was higher that for > 500 mTorr.

The Potential of Renal Progenitor Cells in Kidney Diseases: Preclinical Findings

조정현,김기훈,김태민 사단법인 한국동물생명공학회 2019 한국동물생명공학회지 Vol.34 No.2

The kidney is a highly complex organ, and acute or chronic renal diseases can occur with various complications such as diabetes and hypertension. So far, no target specific treatment is available in acute or chronic renal failure, necessitating the development of alternative therapeutic strategy. Recent experimental findings suggest that the renal function and structure can be restored after being treated with various sources of stem/progenitor cells. In this review, we discuss up-to-date findings of the potential of renal progenitor/stem cells in alleviating renal injuries with a focus on preclinical studies. We also review cellular mechanisms underlying the therapeutic function of these cells.

본 논문은 클립아트 이미지로부터 색상정보와 모양정보를 추출한 후에 다른 클립아트 이미지로부터 추출된 색상정보와 모양정렬 사이의 유사성을 측정하는 방법에 대해 제안한다. 클립아트 이미지의 모양정보를 표현하기 위해서, 제안된 방법은 사각형의 비율을 이용해서 외각선을 오목면과 볼록면의 비율로 표현한다. 모양의 외각선은 사각형으로 표현되고 체인 코드로 변환한다. 반면에, 색상은 HSV 색상 좌표계로 양자화된 간 색상 영역사이의 위치 정보 그리고 색상 영역사이의 크기로 표현된다. 이 색상정보는 자연 이미지보다 적은 칼라수를 가지는 클림아트를 표현하는 데 있어 보다 나은 정확성을 갖는다. 실험 결과는 모양과 색상을 표현하는 데 있어 이전에 연구되었던 방법보다 제안된 방법이 우위에 있음을 보여준다.
