약국 자동화 관리 시스템에서 변위 센서를 이용한 약품 수량 정확도 개선
박기영,김호영,정회경,Park, Kiyoung,Kim, Hoyoung,Jung, Hoekyung 한국정보통신학회 2019 한국정보통신학회논문지 Vol.23 No.9
기존 약국 자동화 시스템에서는 약품 최초투입 시, 설비 운용 중에 수량 측정을 하지 않은 채 메모리 상에서만 수량 관리를 해왔다. 이로 인해 설비의 오류 시 운용 도중 이미 차감되어 버린 약품에 대한 수량 관리가 이루어지지 않았다. 수량 관리가 되지 않아 관리가 필요한 중요한 약품의 경우 심각한 문제를 야기하고 있다. 또한 설비 외부에 약품에 대한 잔량을 사용자에게 알려주는 부분이 없어 사용자는 해당 약품의 재고 소진 시 약품을 다시 채워 넣어야 했다. 약품의 재고 소진 시 설비는 운용을 멈추기 때문에 재가동까지의 시간과 해당 약품을 다시 채워 넣는 시간까지의 손해를 가진 채 운영되고 있다. 이에 본 논문에서는 약국 자동화 관리 시스템의 로봇에 변위 센서를 추가하여 약품들의 수량을 수시로 관리하는 시스템을 설계 및 구현하였다. In the existing pharmacy automation system, quantity control was carried out only in the memory without first measuring the quantity of the medicine and during the operation of the facility. As a result, the number of drugs that have already been deducted during operation at the time of a facility error has not been managed. Serious problems are caused by important medicines that need to be managed because of lack of quantity control. In addition, the user had to refill the drug when it was exhausted because the user could not know the amount of the drug outside the facility. When the drug was out of stock, the facility was operating with loss of time to restart and the time to replenish the drug. Thus, in this paper, we designed and applied system to control the quantity of medicines frequently by adding displacement sensors to the robot of the facility.

Objective : Recently, many studies have showed the evidences of the effect of acupuncture treatment through scientific methods. We performed electro-acupuncture on Taixi(K3) and observed the change of brain activity using fMRI. Methods : To see the effect of electro-acupuncture stimulation on Taixi(K3), the experiment was carried out on twelve healthy volunteers, using the gradient echo sequence with the 3.0T whole-body fMRI system(ISOL). After the needle insertion on K3, 2 Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 seconds' intervals. Result & Conclusions : Unilateral electro-acupuncture stimulation on K3 increased the brain activity in Brodman Area 8, 6, 9, 13, 21, 22, 38, 40, 43, 2, 5, 10, 20, 24, 32, 34, 37, 39, 41, 42. and decreased the brain activity in Brodman Area 9, 13, 38, 22, 31, 3, 6, 10, 21, 25, 29, 30. Group Averaged Brain activity induced by Unilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 10, 22, 42, 43, 44 and was decreased inn Brodman Area 6 and pyrogen test of Bee venom. Bilateral electro-acupuncture stimulation on k3 increased the brain activity in Brodman Area 22, 3, 19, 4, 13, 17, 21, 41, 42, 2, 5, 6, 7, 18, 23, 29, 30, 31, 40 and decreased the brain activity in Brodman Area 18, 6, 39, 4, 13, 2, 10, 19, 36, 40, 45, 46, 47. Group Averaged Brain activity induced by Bilateral Electro-acupuncture Stimulation on K3 was increased in Brodman Area 22, 13, 4, 3, 29, 38, 43 and was decreased in Brodman Area 18, 3, 19, 22, 39. Motor Stimulation activated Brodmann Area 6, 43, 18.
축산폐수 고도처리를 위한 미세조류 Scenedesmus acuminatus의 이용 가능성
박기영,임병란,이기세,이수구,Park, Ki-Young,Lim, Byung-Ran,Lee, Ki-Say,Lee, Soo-Koo 한국농공학회 2011 한국농공학회논문집 Vol.53 No.1
The green algae Scenedesmus acuminatus was cultured in different media: animal wastewater and an artificial culture medium in order to evaluate potential use for tertiary treatment. The experiments were conducted with air flowrate 1~2 L/min at $28{\sim}30^{\circ}C$. The nitrogen and phosphorus showed very similar removal efficiencies (68~77 % and 69~80 % for nitrogen and phosphorus respectively). The optimal fed period was estimated as three days in the semi-continuous experiment. The effects of $CO_2$ (4.5 %) injection on nutrient uptake from animal wastewater (biological treatment effluent) were compared to an air injection under the same conditions of light and photoperiod. The uptake rates of nutrient with air injection were observed 0.009 gN/gChl-a/day, 0.028 gN/gChl-a/day and T-P 0.003 gP/gChl-a/day for nitrate, total nitrogen and phosphorus respectively. The rates were enhanced by addition of $CO_2$ to 0.026 gN/gChl-a/day, 0.076 gN/gChl-a/day and T-P 0.018 gP/gChl-a/day. This study establishes that $CO_2$ addition during nutrient deprivation of microalgal cells may accelerate tertiary wastewater treatment.
