  • Shoot weight of Orostachys japonicus should determine its profitability. The study was done to determine the effect of phosphorus and potassium fertilization (0, 5, 10, 20 kg $P_2O_5$ or $K_2O$ /1000 $m^2$) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 4 weeks to Nov. 16. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length, number of leaves including bracts and stem diameter were increased with increased P and K levels. Leaf and bract, floret, shoot and total dry weights showed similar response to the above morphological characters although P fertilization more increased them than K fertilization. Florets were more formed with increased P and K levels but were not flowered due to the night-break treatment, meaning that P and K fertilization had little effect on anthesis of the florets formed.

  • Social Network Service는 웹상에서 인맥관계를 강화시키고 새로운 인맥을 쌓으며 폭넓은 인적 네트워크를 형성할 수 있도록 해주는 서비스로 지금 현재 사람들끼리 빠르게 많은 정보를 공유할 수 있고, 많은 사람들을 사귈 수 있다는 점에서 각광을 받고 있다. 키넥트는 센서를 통해 사용자의 동작을 인식하는 기계로 별개의 컨트롤러 없이 사용자의 신체만을 이용하여 다양한 게임과 엔터테인먼트를 경험할 수 있기 때문에 남녀노소 모두가 쉽게 즐길 수 있다는 장점이 있다. 또한 동작인식이라는 기능 때문에 본래의 목적인 게임용이 아닌 다른 여러 분야에서 응용되어 사용되고 있다. 본 논문에서는 소셜 네트워크 서비스에서 할 수 있는 정보공유와 인맥강화를 키넥트를 이용하여 보다 동적인 소셜 네트워크 서비스를 구축하는 것을 목적으로 한다. 키넥트의 동작인식 센서와 음성인식 센서를 이용하여 소셜 네트워크 서비스 중의 하나인 페이스북의 기능을 사용할 수 있게 한다.

  • Various presowing seed treatments have been used to enhance the rates of germination and afterward seedling emergence. Seeds treated by them occasionally have not shown the same rate in indoor and field. The presowing treatments considering germination mechanism and factors affecting germination should be totally included in indoor experiments so that the results drawn could be reproduced in the field. Seed drying after the treatments and field conditions after sowing especially able to show Phytochromemediated responses related to light treatment must be determined prior to force the treatments to seeds. After set up these prerequisites to promote the rates of germination and emergence, many seed treatments proposed so far must be fixed how to be done; alone, sequential and simultaneous.

  • 최근 우리사회는 다양한 형태의 여가활동 및 생활체육에 대한 국민적 욕구와 열망과 더불어서, IoT기술발전 및 시장확대에 힘입어 다양한 스마트 자전거 제품이 등장하고 있다. 그러나 기존 제품의 경우 속도계 장치에 의한 주행기록을 분석할 수 없고, 스마트폰 앱의 경우에는 정확한 데이터 측정이 불가능하다. 이러한 문제점을 해결하기 위하여, 본 논문에서 개발한 스마트 자전거는 마그네틱 센서를 이용하여 거리, 속도, 시간 등을 측정/분석하고, 라이딩 정보를 어플리케이션에 저장하여 사용자가 라이딩 정보를 언제든 살펴볼 수 있다. 또한, 라이딩 속도에 따라서 LED의 색상이 변경되어 익스트림 라이딩 모드 및 LED제어, 스마트 자물쇠 기능 등을 제공한다.

  • For research of the wintering waterbirds we surveyed monthly from October 2000 to March 2001 on Gangjin Bay, Chollanam-do, Korea. During the study period, the waterbirds were observed 9,825 individuals and 36 species. The highest dominant species was Anaspiatyrhynchos which occupied the $48.42\%$, the one followings were Anas crecca $(10.8\%)$, Tadorna tadorna $(9.7\%)$, Anas poecilorhyncha $(9.5\%)$ and Cygnus cygnus $(4.8\%)$. A regularly observed species in every months were 3 species, Egretta garzetta, Anas pin tyrhynchos and Anas poecilorhyncha. The Cygnus cygnus of specially protected species was observed the 232 individuals maximumly in November and the 125 individuals to a minimum in December. The index of species diversity was minimum 1.24 at October and maximum 2.01 at March. This area has provided a suitable roosting and feeding place for waterbirds. The peak count of the wintering whooper swan was 232 individuals in Gangjin Bay. Therefore, We need the conservation and management of Gangjiun Bay.

  • The surface treatment technique to increase corrosion resistance is very important in mechanical components of structures. Therefore, this paper investigates the effects of shot peening on the corrosion resistance of SCM 420steel. The results show that the surface compressive residual stress largely increases, which cause the increase of corrosion resistance.
