As rapid development of new hardware control interface technology, new concepts have been being proposed and emerged. In this paper, a new approach based on leap motion system is proposed. While we employ a position information from sensor, the hand gesture recognition is suggested with the pre-defined patterns. To do this, we design a recognition algorithm with hand gesture and finger patterns. We apply the proposed scheme to 3-dimensional avatar controling and editing software tool for making animation in the cyber space as a representative application. This proposed algorithm can be used to control computer systems in medical treatment, game, education and other various areas.

화재 경보 시스템은 안드로이드, MEAN 스택을 이용한 서버와 데이터베이스, 아두이노를 이용한 장치를 통해 사용자에게 온도, 가스농도 정보와 화재 발생 유무를 알려준다. 화재 시 빠르게 대처, 대피 할 수 있고, 또한 경보를 울리도록 만들었다. 또 애플리케이션을 통해 데이터베이스 서버에 적재된 최신의 데이터 값들을 받아와 표와 그래프로 보여준다.

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.

In this paper, we first applied the chemical mechanical polishing (CMP) process to the planarization of ferroelectric film in order to obtain a good planarity of electrode/ferroelectric film interface. $Pb_{1.1}(Zr_{0.52}Ti_{0.48})O_3$ (shortly PZT) ferroelectric film was fabricated by the sol-gel method. And then, we compared the structural characteristics before and after CMP process of PZT films. Their dependence on slurry composition was also investigated. We expect that our results will be useful promise of global planarization for ferroelectric random access memories (FRAM) application in the near future.

The sunlight tracking and reflexing system can be divided into two parts. One is a sunlight tracking system and the other is a sunlight reflexing system. The sunlight tracking system detects an azimuth angie and an elevation angle of the sun using 2-axis sensor sun tracker. The sunlight reflexing system controls a reflection mirror to be reflected a sunlight at the target area after getting the azimuth angle and the elevation angle of the sun from the sunlight tracking system. We applied the fuzzy PID controller to control the reflexing mirror.

The tracking system on the moving vehicle is made up of two parts. One is a stabilizer which is flatting the system against the moving vehicle, the other is a tracker which is tracking the target. This makes use of the geometric information of the tracking target and that utilizes the dynamic information of the moving vehicle equipping the tracking system. Especially the stabilizer is very important for an ocean vehicle affected by wave, wind, and current. In this paper, the stabilizer of sun tracking system for a ship is developed.

Vitelllogenin(Vg) is a sex specific protein appearing in the blood of sexually maturing female fish as well as other oviparous vetebrates. It is synthesized in the liver in response to estradiol-l7$\beta$(E$_2$). Although E$_2$ is a main induce. of Vg synthesis, other hormonal requirements have also been reported to be important in Vg synthesis(lazier et al., 1996; Peyon et at., 1997). (omitted)

An open reading frame, designated GerGTII and located downstream of the polyketide synthase genes, has been identified as a chalcosyltransferase by sequence analysis in the dihydrochalcomycin biosynthetic gene cluster of Streptomyces sp. KCTC 0041BP. The deduced product of gerGTII is similar to several glycosyltransferases, authentic and putative, and it displays a consensus sequence motif that appears to be characteristic of a sub-group of these enzymes. Specific disruption of gerGTII within the S. sp. KCTC 0041BP genome by insertional in-frame deletion method, resulted complete abolishment of dihydrochalcomycin and got the 20-O-mycinosyl-dihydrochalconolide as intermediate product in dihydrochalcomycin biosynthesis which was confirmed by electron spray ionization-mass spectrometry and liquid chromatography-mass spectrometry. Dihydrochalcomycin also was recovered after complementation of gerGTII.

본 논문에서는 홍통거리의 신축 건물과 리모델링 건물을 통한 재생 건축의 조화의 방법에 대해 모색해 보고, 해결방안을 제시해 보도록 한다. 현재 홍통거리는 거리의 발전에 따라 오래된 건축물들을 리모델링한 건물과 신축건물들이 생겨남에 따라, 두 건물과의 조화된 모습을 찾고자 한다. 조화된 거리의 모습을 이루기 위해 거리 바닥 패턴과 일관된 시설물을 통해 거리의 형성을 해나가야겠다.
