Transformer-Reuse Reconfigurable Synchronous Boost Converter with 20 mV MPPT-Input, 88% Efficiency and 37 mW Maximum Output Power

임종필,문승언,여준기 한국전자통신연구원 2016 ETRI Journal Vol.38 No.4

This paper presents a transformer-based reconfigurable synchronous boost converter. The lowest maximum power point tracking (MPPT)-input voltage and peak efficiency of the proposed boost converter, 20 mV and 88%, respectively, were achieved using a reconfigurable synchronous structure, static power loss minimization design, and efficiency boost mode change (EBMC) method. The proposed reconfigurable synchronous structure for high efficiency enables both a transformer-based self-startup mode (TSM) and an inductor-based MPPT mode (IMM) with a power PMOS switch instead of a diode. In addition, a static power loss minimization design, which was developed to reduce the leakage current of the native switch and quiescent current of the control blocks, enables a low input operation voltage. Furthermore, the proposed EBMC method is able to change the TSM into IMM with no additional time or energy loss. A prototype chip was implemented using a 0.18-μm CMOS process, and operates within an input voltage range of 9 mV to 1 V, and an output voltage range of 1 V to 3.3 V, and provides a maximum output power of 37 mW.

Lead acetate and Bojungiki-tang extract, a herbal restorative were treated p.o. 40㎎/㎏ and 500㎎/㎏ respectively and concurrently to mouse, and examined blood biochemical parameters and effects of metabolic enzymes of rats. The results obtained in this study are as follows: 1. The value of aspartate aminotrasferase(AST) of lead-treated group increased while the group of concurrent administration with BIT showed significant decrease and the value of alkaline phosphatase(ALP) of lead-treated group decreased while the group of concurrent administration with BIT showed significant increase. 2. The value of δ-aminolevulinic acid dehydratase(ALAD) of lead-treated group de creased while the group of concurrent administration with BIT showed significant in crease and the values of cytochrome p-450 in liver and kidney of lead-treated group increased while the group of concurrent administration with BIT showed significant decrease. The differences (%) of aniline hydroxylase and 2-thiobarbituric acid (TBA) of lead-treated group increased while the group of concurrent administration with BIT showed significant decrease. These results on the whole indicated that concurrent administration with BIT showed significant recovery from the toxicity of lead-treated group.

補中益氣湯이 납中毒된 흰쥐의 臟器重量에 미치는 影響

임종필,남궁동,강창수,강태욱 又石大學校 1994 論文集 Vol.16 No.-

Lead acetate and Bojungiki-tang extract, a herbal restorative were treated p. o. 40㎎/㎏ and 500㎎/㎏ respectively and concurrently to mouse, and examined variation of body weigh, accumulation of lead in organs of rats. The results obtained in this study are as follows: 1. Bojungiki-tang extract(BIT) resulted increase of body weight and the increase ratio of body weight in lead-treated group was dropped but the group of concurrent administration with BIT showed significant recovery. 2. The accumulation of lead in liver of lead-treated group increased but the group of concurrent administration with BIT showed significant decrease. 3. The ratio of liver weight/body weight of lead-treated group increased but the group of concurrent administration with BIT showed significant decrease. These results on the whole indicated that concurrent administration with BIT sowed significant recovery from the toxicity of lead-treated group.

半夏瀉心湯과 Cimetidine의 병용투여가 흰쥐의 위궤양에 미치는 영향

林鍾弼,卜鎭尤 又石大學校 1988 論文集 Vol.10 No.-

Banhasasim-tang, chinese medicine, has been used for the treatment of the gastric ulcer and cimetidine, H_2-receptor blocker, has been also used as the gastric ulcer remedy. Therefore the concurrent administration of these two drugs may increase antiulcer activities more than administrating one by one. In order to investigate antiulcer activities, some experiments were conducted. The results obtained were as follows; 1.The concurrent administration of Banhasasim-tang and cimetidine given intraperitoneally (cimetidine 50㎎/㎏+extract 300㎎/㎏ and 50㎎/㎏+500㎎/㎏), significantly inhibited Shay ulceration in rats (12 hr ligation). 2.Aspirin ulcers induced by the administration of aspirin 200㎎/㎏(p.o) to pylorus-ligated rats were inhibited by the concurrent administration of Banhassasim-tang and cimetidine. The combination of these two drugs (cimetidine 50㎎/㎏+extract 100㎎/㎏, 50㎎/㎏+300㎎/㎏ and 50㎎/㎏+500㎎/㎏) resulted in a potentiated effect on the inhibition of the ulceration. 3.Indomethacin ulcers induced by intraperitoneal injection of indomethacin 20㎎/㎏ were inhibited by the concurrent administration of Banhasasim-tang and cimetidine. The combination of these two drugs (cimetidine 50㎎/㎏+extract 100㎎/㎏. 50㎎/㎏+300㎎/㎏ and 50㎎/㎏) resulted in a potentiated effect on the inhibition of the ulceration. 4.The antiulcer actions by the concurrent administration of Banhansasim-tang and cimetidine against Indomethacin ulcers were more effective than those against Aspirin ulcers or shay ulcers.

The popularity of the Korean Wave continues to increase around the world. As an image that comes to mind when it comes to korea selected by overseas consumers, K-Pop was ranked first for five consecutive years, and the addictive chorus was selected as the reason why K-Pop is popular. Therefore, this study aims to derive the characteristics of the K-Pop idol group chorus. The research scope of this study was selected through three stages on the music portal site Melon’s historical chart, and a total of 120 subjects were analyzed. As a result of the analysis, it was confirmed that the K-Pop idol group chorus began with the first generation and proceeded with each generation, and the technique of reducing or simply repeating the transformation of a given motive was frequently used. As a result of this study, the characteristics and changes of the K-Pop idol group chorus by generation were confirmed by a method called melody development technique.

복강 내 종괴로 나타난 림프절 전이를 동반한 분화형 점막 위암 1예

In early gastric cancer, the most important prognostic factor is the presence or absence of a lymph node metastasis that is associated with the tumor size, histopathological differentiation, depth of tumor invasion and lympho-vascular invasion. A small sized differentiated mucosal cancer without a lympho-vascular invasion or histological ulceration rarely metastasizes to the lymph node. Herein, we report a case of a lymph node metastasis that is presented as an intra-abdominal mass in a 2.5 cm-sized differentiated mucosal cancer without ulceration or lympho-vascular invasion. (Korean J Gastrointest Endosc 2007;35:429-434) 조기 위암에서 림프절의 전이 여부는 환자의 예후에 가장 중요한 요인으로 림프절 전이는 종양의 크기, 분화도, 침범 깊이, 림프관과 혈관의 침범 여부 등과 연관이 있다. 즉, 크기가 작고 림프관 및 혈관을 침범하지 않은 분화형 점막암은 거의 림프절 전이를 하지 않으며, 궤양을 동반하지 않은 경우에는 종양의 크기에 상관없이 림프절 전이는 드문 것으로 알려져 있다. 최근 저자들은 궤양을 동반하지 않은 2.5 cm 크기의 점막에 국한된 분화암에서 림프관 및 혈관의 침범 없이 복강 내 종괴의 형태로 림프절 전이를 보인 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
