임베디드 프로세서를 이용한 스마트 배터리 관리 시스템 구현에 대한 연구
오창록,이성원,Oh, Chang-Rok,Lee, Seong-Won 한국전기전자학회 2011 전기전자학회논문지 Vol.15 No.4
최근 휴대 가능한 스마트폰, 노트북과 같은 모바일 기기의 수요가 급격하게 늘어나고 있다. 또한 이러한 기기는 한 제품에 여러 기능을 추가하는 복합화와 대용량의 멀티미디어 기능과 같은 스마트 기능이 주류를 이루면서 더 많은 전력을 소모하게 된다. 이에 따라 기존의 속도와 성능을 향상시키기 위한 노력에서 한정된 배터리 용량을 효율적으로 사용하여 효율을 극대화 시키려는 노력으로 변화하고 있다. 본 논문에서는 임베디드 프로세서를 이용해 이벤트 드리븐 프로그래밍 방식을 사용한 배터리 관리 시스템을 제안하고 제안된 시스템이 SBS(Smart Battery Specification) v1.1을 만족 할 수 있음을 보였다. 제안하는 배터리 관리 시스템의 특징은 기존의 임베디드 시스템에서 실시간 운영체제를 이용한 배터리 관리 시스템에 비해 전체 코드 크기와, 필요한 메모리 크기를 줄 일 수 있다. 또한 Firmware 형태로 구성하여 쉽게 기존의 운영체제에 포함 할 수 있다. Recently portable mobile devices such as smart-phones and notebooks have rapidly increasing demands. Those devices consume more power because they are expected to offer more complex functionality including multimedia features. For these reasons engineering efforts are changing to focus on maximizing energy efficiency within a limited battery capacity instead of increasing computational performance. In this paper, we propose a battery management system using event driven programming technique on a embedded processor. We also show that the proposed system satisfies SBS (Smart Battery Specification) v1.1. The proposed system maintains minimum code size and memory size comparing to those of RTOSs. The proposed system can be also easily incorporated in the conventional RTOSs as a form of firmware.

Objectives : The pain was induced on upper and lower incisor of the rat based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'. Such acupoints as LI4 and ST36 were used for alleviation of upper and lower incisor pain. Methods : The digastric myogram (dEMG) was utilized for the pain measurement. Results : The ST36 acupuncture after induction of upper incisor pain was gradually decreased or increased the dEMG. The LI4 acupuncture after induction of upper incisor pain was gradually decreased the dEMG. The ST36+LI4 acupuncture after induction of upper incisor pain was gradually decreased the dEMG. We knew this thing which the ST36+LI4 acupuncture decreased the dEMG most greatly and kept long compared to ST36 acupuncture, LI4 acupuncture. Conclusions : Acupuncture treatment at the loci of not only ST36 acupuncture but LI4 acupuncture were relieved the upper incisor pain. It was well suitable to the theory 'connections of upper incisor pain with stomach meridian' that ST36 acupuncture decreased the upper incisor pain. But there was not to decrease the dEMG for the ST36 acupuncture. We are considered as tracing study continuously about ST36 acupuncture. It was not suitable to the theory 'connections of upper incisor pain with stomach meridian' that LI4 acupuncture decreased the upper incisor pain. These results was considered as the function by the characteristic of the LI4 acupoint.

Teratogenicity of triamcinolone acetonide on palatogenesis with special reference to changes of carbohydrate residues in cell surface macromolecules, which have known to play an important role in development of the secondary palate, during the process of the steroid-induced cleft palate in DDY mouse were investigated immunohistologically using lectins, such as Concanavalin A (Con A), Ricinus communis agglutinin (RCA), wheat germ agglutinin (WGA), soybean agglutinin (SBA), Dolichos biflorus agglutinin (DBA), peanut agglutinin (PNA), Pinellia ternata agglutinin (PTA) and Ulex europaeus agglutinin (UEA) by application of biotin-avidin peroxidase and benzidine substrate. Morphologically, triamcinolone changed the shape of palatal shelves to thick, short and blunt in their edges and delayed shelf elevation, consequently palatal epithelial contact itself was impossible even after shelf elevation. Con A reactivity to shelf epithelia and mesenchyme was markedly increased just prior to shelf elevation and continued until epithelial contact but rapidly decreased after fusion, whereas TA inhibited its increment prior to shelf elevation but it recovered thereafter with shelf elevation in delayed schedule. Prior to shelf elevation, reactivity with RCA and WGA were increased but decreased after elevation. while TA decreased or inhibited their reactions before shelf elevation but the reactivities were increased with/after elevation with RCA and transiently with shelf elevation with WGA. UEA, SBA, DBA, PNA and PTA showed negative reaction to the developing palatal tissues both in control and TA treated. With the results, it seems that triamcinolone inhibits synthesis of α-D-glucosyl, α-D-mannosyl, β-D-galactosyl residues and sialic acid containing macromolecules and these components could be related to not only shelf elevation and epithelial fusion but also final growth/extension of the shelves.

Objective : The purpose of this study is to establish a category for acupuncture therapy by appropriate etiological analysis and differenciation of edema. Methods : We arrange Huang Di Nei Jing and thirty four kinds of literature about edema. Results : 1. The cause of Edema is functional disorder of lung, spleen, kidney, bladder and tri-energizer by six kinds of natural factors, internal injury and loss of nutritions. 2. Edema compartmentalize into the water of five zang organs, several kinds of edema(e,g. 5, 10, 12, 24) and yang & yin edema. 3. An ultimate cause of edema pathogenesis is the disturbance of Qi function in kidney. 4. In view of the results so far achived, ‘GV26(水溝)’ is a vitally important acupoint in acupuncture treatment of edema. ‘GV26(水溝)’ and ‘CV9(水分)’ are very useful acupoints in moxibustion. 5. In the acupuncture and moxibustion treatment of yang edema, we can use acupoints as like ‘GV26(水溝)’,‘S36(足三里)’,‘B20(脾兪)’ and ‘SP9(陰陵泉)’ by purgation and reduction for expelling wind, reducing fever and eliminating dampness. In an instance of yin edema, we can use acupoints as like ‘CV9(水分)’,‘S36(足三里)’,‘CV6(氣海)’,‘B20(脾兪)’,‘B23(腎兪)’ and ‘K3(太谿)’ by reinforcement for tonifying spleen yang-middle energizer-, qi-transmission and water promoting.
