This study has been carried out to understand the effect of Danchisoyosangagambang (DC) on the hyperglycemic mice induced with streptozotocin(STZ). Experimental groups were made diabetic mice by intraperitoneal injection of STZ(60 mg/kg of body weight) tw ice by 24 h interval and then 120 mg/kg STZ was injected again 3 days after the earlier treatment. Control group was administered mice with 0.9 % saline(2 mL/kg), and experim ental groups were administered DC extract(DCA group, 10 mg/kg/day; DCB group, 30 mg/kg/day) after hyperglycemic induction for 6 weeks. The body weight of experimental groups was lower than control. The blood glucose concentration increased continuously, rea ching to 298.9 mg/dL after 6 weeks, however, experimental groups of the DCA and DCB groups significantly(p<0.0l) decreased in the 4, 5, and 6 weeks groups. Blood glucose tolerance test was not significant between control and experimental groups. We examined the blood transaminase activities to know the effect of herbal medicine on liver function. The GOT activities were lower in group DCB than in control. The GPT activities were lower in group DCA and DCB than in control. The content of triglyceride was significantly increased in group DCA compared to control. The SOD and catalase activities were higher in the group DCA compared to control. The results of immunohistochemical study, a few of insulin positive cells observed in the control and experimental group. These results suggest that administration of DC extract to the hyperglycemic mice decreased the blood glucose level.

Most designers of equipment, or of a workplace layout, frequently choose 5 percentile female and 95 percentile male dimensions as design limits. If the design is not an one-dimensional problem, it is difficult to choose '5 percentile female' or '95 percentile male'. Hence it is important to consider the interactions or relationships between body dimensions. This paper deals with correlation analysis, factor analysis and partial correlation analysis using data above age 20 from the national anthropometric survey in Korea, 1986. Besides, a model which represent the extremes of body size of Korean has been developed in this paper.

Residence time is defined as the time taken for a material in a system to leave the system. The residence time characteristics in shellfish aquaculture determine the dispersion of excretion from aquaculture farms, along with the supply of food by seawater exchange. In this study, we estimated the spatial distribution of average residence time in the shellfish farming area using a particle tracking model. As a result, a relatively short average residence time of about 20 days or less was calculated in most areas, but an average residence time of more than 40 days was calculated in the inner areas. Relatively long average residence times were calculated along the west coast compared to the east coast, with the longest average residence time of more than 50 days in the northwestern areas. It can be inferred that the disturbance of the benthic ecosystem caused by shellfish farms is likely to be large because of the relatively weak dispersion of excrement from shellfish farms located on the west coast, especially in the northwest region. This distribution of average residence time is important for understanding the potential effects of seawater exchange on the environmental sustainability of shellfish farms, along with the seawater circulation characteristics of Jaran Bay.

PMMA 입자의 표면에 양전하를 갖는 전해질 폴리머 PDDA와 음전하를 갖는TALH를 사용하여 $TiO_2$ 박막을 LBL 법에 의해 성공적으로 제조하였다. 수정진동자의 측정을 통해 TALH의 용액의 pH가 감소됨에 따라 TALH의 적층량이 늘어나고 PMMA의 입자 표면에 코팅된 (PDDA/TALH) 박막의 두께가 증가됨을 확인하였다. (PDDA/TALH)n의 순서에 의해 코팅된 PMMA 입자들은 bilayer 수의 변화에 따라 다양한 색 변화를 보여주었다. (PDDA/TALH) 박막의 bilayer 수(n)가 10과 20 일 경우에 $a^*$와 $b^*$의 값은 막이 코팅되지 않은 PMMA의 값보다 감소하였고 색 변화는 $a^*$, $b^*$ 색도도에서 각각 green과 blue 방향으로 이동하였다. 이후 n의 수가 30, 40으로 증가됨에 따라 $a^*$와 $b^*$의 값은 증가하였고 색의 변화는 red와 yellow 방향으로 각각 이동하였다. 최종적으로 $(PDDA/TALH)_{50}$ 박막이 코팅된 PMMA 입자들은 박막이 코팅되지 않은 PMMA 입자들과 거의 비슷한 $a^*$와 $b^*$의 값을 보여주었다. $TiO_2$ thin films consisting of positively charged poly (diallyldimethylammonium chloride) (PDDA) and negatively charged titanium (IV) bis (ammonium lactato) dihydroxide (TALH) were successfully fabricated on a poly (methyl methacrylate) (PMMA) by layer-by-layer (LBL) self-assembly method. By the measurement of quartz crystal microbalance (QCM), it was found that as the solution pH of TALH decreased, the deposition volume of TALH increased and the thickness of (PDDA/TALH) thin film coated on the surface of PMMA particles increased. The PMMA particles coated with the coating sequence of (PDDA/TALH)n showed the variation of color changes as a function of the number of bilayer. The number of bilayer (n) of (PDDA/TALH) thin films was 10 and 20, the values of $a^*$ and $b^*$ decreased from those of PMMA particles without coating films and the color changes was shifted to green and blue direction in the $a^*$, $b^*$ chromaticity diagram. And then, the number of n increased to 30 and 40, the values of $a^*$ and $b^*$ increased and the color changes was shifted to red and yellow direction, respectively. Finally the PMMA particles coated with $(PDDA/TALH)_{50}$ thin film showed a little same value of $a^*$ and $b^*$ with the PMMA particles without (PDDA/TALH) thin film.

김진호,이주용,김태완,Kim, Jin-Ho,Lee, Joo-Yong,Kim, Tae-Wan 대한토목학회 2015 대한토목학회논문집 Vol.35 No.3

지하철 역사 내 계단, 통로, 그리고 에스컬레이터 등의 보행 시설물에서 발생하는 서로 다른 방향의 보행교통류간 상충은 보행자의 편의와 이동성을 감소시킨다. 또한, 각 시설물별 지체 시간과 대기 행렬의 증가를 수반함에 따라 역사의 이용효율을 저하시키게 된다. 이러한 현상은 보행교통류간의 동선이 겹치면서 발생하는 것으로 동선을 방향에 따라 적절히 분리해줄 경우 완화될 수 있다. 하지만 우선 동선 분리의 기준과 그 방법론에 대한 정립이 선행되어야 한다 할 수 있다. 본 연구에서는 계단, 통로 그리고 에스컬레이터로 분류되는 각 시설물의 입구를 기준으로 방향별 대기 행렬과 지체시간을 도출하였다. 이 때, 시설물의 보행교통류는 양방향으로 존재하므로 지체시간은 각 방향별 유입 인원에 따라 가중 평균한 값을 활용하였다. 또한 동선 분리 시스템의 운영을 최적화하기 위해 유전 알고리즘을 활용하여 보행자의 지체시간을 최소화하였다. The conflict of opposing pedestrian traffic-flow in a subway station(made up of stair, passageway, and escalator) diminishes the convenience and mobility of its users. In addition, the station's efficiency would be negatively affected by the growth of delay and queue length in pedestrian facilities. As these phenomena have been resulted by the overlapping in pedestrian's traffic-line, the separation of it would alleviate these problems. For the criteria and methodology of separation, this paper has investigated the bi-directional queue length and delay on the entrance of each facility (stair, passageway and escalator). Since the pedestrian flow exists bidirectionally, we have used the weighted average by inflow rate for the delay value. For the optimization of the separation, the Genetic Algorithm has been utilized in order to minimize the delay.

EMR(Electronic Medical Record)이란 종이문서 방식을 사용하는 의료차트 대신에 모니터로 출력되는 형식의 의료차트를 말한다. 현재 통용되는 EMR은 전문 의료인이 전문적인 용어 써놓은 양식이기 때문에, 그 의료기록의 실제 주인인 환자는 의료인의 부가적인 설명 없이는 자신의 자세한 증세는 물론 병명조차 정확히 확인하기 힘들다. 이에 환자에게 있어 매우 시간 소모적이고 노동집약적인 과정으로 환자가 의료인을 거쳐서 자신의 의료정보를 얻는 방식보다는 환자가 직접 그 정보를 얻는 방식이 필요하다. 따라서 본 연구는 EMR이 갖는 이러한 문제를 해결하기 위해 환자가 의료인을 거치지 않고 직접 자신의 의료정보를 얻기 위한 환자 접근행 EMR 응용 시스템의 비즈니스 모델을 제시한다. EMR(Electronic Medical Record) is being broadly used in general medical institution, but it could be more efficient and convenient if patients could use it themselves. Because present EMR is the formula written by medical experts with professional words, the patient can not identify his detailed symptoms and even the name of disease. Otherwise, the patient should have many efforts for obtaining his medical records. To solve this problem, this study developed Patient-Accessible EMR system, which was founded as one of patient-centric medical services, and it shows that the patient can take his medical information without medical experts.

In this study, the higher temperature thermal property of the fly ash-blast furnace slag system Geopolymer including alumina aggregate was investigated whether that Geopolymer will be or not useful as thermal-resistant construction materials. Under every mixing conditions, the crack on the surface of hardened body was not observed up to $800^{\circ}C$ and it corresponded with fact that level of changes was not significant before and after heating process. Residual compressive strength is most high when mixing Blast-Furnace Slag ratio is 60 wt% until temperature reaches $800^{\circ}C$. The major hydrates of hardened body of Geopolymer; amorphous halo pattern between $20{\sim}35^{\circ}$ (2theta) and mullite ($3Al_2O_3{\cdot}2SiO_2$) and quartz ($SiO_2$) was found during the experiment. Amorphous halo pattern was a aluminosilicate gel generated by geopolymeric polycondensation and it was found that the halo pattern of aluminosilicate gel was preserved up to $800^{\circ}C$. The patterns of aluminosilicate gel disappeared from $1,000^{\circ}C$ and crystal phases like gehlenite, calcium silicate, calcium aluminum oxide, microcline was observed with the increase of exposure temperature. 본 연구에서는 Alumina 골재를 사용한 fly ash-blast furnace slag계 Geopolymer의 내열성 건축자재로서의 사용 가능성을 검토하기 위하여 고온조건에서의 열적 특성에 대하여 조사하였다. 모든 배합조건에서 Geopolymer 경화체의 표면 크랙은 $800^{\circ}C$까지는 관찰되지 않았으며, 이것은 열처리 전후 강도의 변화가 작은 것과 일치한다. 또한, $800^{\circ}C$까지 고로슬래그의 혼합비율이 60 wt%일 때 잔존압축강도가 가장 우수한 것으로 나타났다. Geopolymer 경화체의 주요 수화 생성물은 $20{\sim}35^{\circ}$(2theta) 범위의 비정질 halo 패턴과 원재료의 mullite($3Al_2O_3{\cdot}2SiO_2$)와 quartz($SiO_2$)가 확인되었다. 비정질 halo 패턴은 Geopolymer 축중합 반응에 의해서 생성된 aluminosilicate gel이며, $800^{\circ}C$까지는 aluminosilicate gel의 halo 패턴이 유지되고 있음을 알 수 있다. $1,000^{\circ}C$에서 aluminosilicate gel의 패턴은 사라지며 열처리온도의 증가와 함께 gehlenite, calcium silicate, calcium aluminum oxide, microcline와 같은 결정상이 관찰되었다.
