Chungbuk has various regional characteristics in terms of population composition by region, industrial facilities, and distribution of emergency medical institutions. However, there are no studies yet that have analyzed regional characteristic factors related to the occurrence characteristics of cardiac arrest patients. Therefore, this study provided basic data to establish a response system for OHCA patients suitable for the characteristics of the Chungcheongbuk-do region by analyzing the characteristics of OHCA patients and the transfer status of 119 paramedics in Chungcheongbuk-do. This study is a retrospective study that analyzed 1,188 cardiac arrest patients transferred by ambulance based on raw data from the survey on acute cardiac arrest in Chungbuk (2020). There are a total of 11 emergency medical institutions in Chungbuk-do, which are concentrated in city-level areas, so the transfer time of patients to hospitals in county-level areas was delayed. In the county-level area, the frequency of dispatch of special paramedics was relatively small, and the frequency of administration of cardiac arrest drugs to help resuscitate cardiac arrest patients was also low. In conclusion, efforts should be made to improve accessibility of emergency medical services (deployment of emergency vehicles in marginal areas, proper placement of emergency medical institutions, etc.), to promote prevention of traumatic cardiac arrest patients, and to expand the scope of work to strengthen the first aid expertise of paramedics.

This study aims to draw the basis documents for rural landscape management of Daewon-Ri through frequency analysis of landscape elements and preference analysis of rural landscape. The results are as follows. First, according to the frequency analysis of the landscape elements, a distant view is few effect characteristics in rural village landscape planning. It is acted as the landscape elements that degree of integration and skyline of the building to see more nearby than it are the most important. In addition, in the case of the establishment of the landscape management planning, the landscape elements in the close view is the most important. Second, It is thought that the scenery which natural environments and residential quarter match is the most desirable for the par of the landscape preference in the rural village. On the other hand, about the scenery of an old historic building, the residents of a city considers it as an affirmative factor of the rural village landscape, but rural village inhabitants are negative. Finally, it is thought that the excessive public designs by government sponsored enterprise are undesirable for the scene of the village.

Thick PZT films are required for the cases of micro actuators and sensors with high driving force, high breakdown voltage and high sensitivity, and so on. In this work, thick PZT films were fabricated by Sol-Gel multi-coating method. Total 8 types of samples using thick PZT films with thicknesses, about $1{\mu}m$ and $2{\mu}m$, and Pt top electrodes shapes for measuring transverse piezoelectric coefficient ($e_{31,f}$) were fabricated using MEMS processes. They were characterized by fabricated e31,f measurement system before and after poling. $e_{31,f}$ values of samples after poling were higher than before poling. Those of $2{\mu}m$ thick PZT films were also higher than $1{\mu}m$ thick PZT films. And those with long electrodes as top electrodes were also higher than shorter.

산불 진화에 사용되는 지상 주력 장비를 대상으로 수원으로부터 호스 거리 및 고도에 따른 성능을 정량화하기 위한 현장 적용 실험을 실시하였다. 대조군으로는 담수지 형태의 수원을 사용하고 수원으로부터 고도차가 40m 수준인 예비실험을 대상으로 성능값을 비교하였다. 본 현장 적용 실험에서는 산림 내 계곡지를 수원으로 하였으며, 고도차가 150m 로 예비실험의 3.75배인 지형을 선택하였다. 고도에 따른 영향이 크지 않은 예비 실험과 비교하였을 때 고도가 높아질수록 동일 거리에서 측정한 성능값은 평균 50% 이상의 감소를 나타내었다. 그러나 수평 및 수직 거리는 20% 이내 수준의 감소를 나타내어 진화에 큰 장애 요소로는 작용하지 않았으며, 펌프압력은 소형펌프의 압력 상승이 가장 큰 상승률을 나타내었다. 이와 같은 결과는 수원의 형태에 따라 용수 공급차에 기인한 것으로 안정적 용수공급 저하, 펌핑압 부하 증가, 이물질 삽입 등이 원인인 것으로 사료되며, 고도에 따른 영향 인자도 반영된 것으로 해석된다. 또한 실험을 통해 진화장비별 실제 진화대원의 적정 사용거리와 거리별 적정 소요인원을 산출할 수 있었다.

Recently, has been the subject of high interest in rural areas. However it incite the damage to rural landscape and destruction of the locality. The reason is the economic logic that potential was ignored of community. In the meantime, has thrown out the importance to restore damaged rural landscape. So, pleasant natural environment and community resources to create value. Therefore, the purpose of this research, redefine the value of the future of rural landscape that the community design and community planning is to offer basic data. The results of study are as follows; First, the landscape that all human perception through the senses, so the community planning to landscape the locality of the formation is a very important element. Second, if it build a new building would have to find space in community. So, the plan must reflect the community and the locality, If so the landscape of th community, the building will be imbibe naturally. Third, the rural area of the rural community when planning for past, present and future should be thoroughly analyzed, and for the future direction of the community will be set up. Finally, analyzing correctly past of the community to reconfigure the rural community is very important. When configure the space of rural community, if created the new space based on original characteristic of the community, the landscape will be kept in rural community.

Background: Recovery of the left atrial contractile function after the Cox-Maze procedure is related to the size of the left atrium. We have postulated that if too wide area of the atrium were isolated electrically, then the atrial contractile function would be impaired postoperatively. We have modified the Cox-Maze procedure to dissect each pair of the pulmonary veins separately instead of the conventional pulmonary vein encircling incision, and compared the atrial contractile function after each procedure. Material and Method: From February 1995 to October 1997, 55 cases of the Cox-Maze procedure were performed in mitral valvular heart disease. We excluded the cases that did not covert to sinus rhythm. The patient groups were divided according to the interpulmonary vein distance(IPVD) and the procedure performed. Group I was IPVD under 6.5 cm(n=30), group II was IPVD over 6.5cm and the conventional Cox-Maze III procedure was performed(n=16), and group III was IPVD over 6.5cm and the modified Cox-Maze procedure was performed(n=9). Result: Atrial contractile function was evaluated by the echocardiography follow-up between 6 months to 12 months. The right atrial contractile function recovered gradually, the recovery rate after long-term follow-up was 90% in group I, 81% in group II, and 100% in group III(p>0/05). In the left atrium the recovery rate was 63% in group I, 31% in group II(p=0.03), and 66% in group III(p>0.05). Conclusion: The modified Cox-Maze procedure may have beneficial effects on the recovery of the left atrial contractile function, however, there are no statistically significant values. Therefore, further evaluation of this procedure is necessary.

The objective of this study was to examinate the differences of general component, chromaticity, pH, weight, loss on baking, specific volume bulk, diameter of upper side and height, mechanical texture, DPPH radical, ABTS radical, Total amount of phenol, Monacolin-K content, sensory test on Muffin using no Red Yeast Rice and different levels (2%, 4%, 6%, 8%, 10%) of Red Yeast Rice. pH was decreased as the amount of added Red Yeast Rice increased(control 8.35, RM2% 7.93, RM4% 7.86, RM6% 7.69, RM8% 7.49, RM10% 7.30). Weight and loss on baking were showed not too different depending the amount of added Red Yeast Rice, and the baking loss were at very low point. Adhesion, cohesiveness, elasticity, viscosity, and chewiness showed no attentive differences on mechanical texture analysis. As the level of Red Yeast Rice increased, DPPH radical, ABTS radical, and Total phenol content decreased. Monacolin K were at higher point as the level of Red Yeast Rice increased. The sensory test showed Taste, Texture, and Overall acceptability gained the highest point when using 4% of Red Yeast Rice. On the sensory test, 4% of Red Yeast Rice was considered to be the best level based on Flavor and Color. The results of these tests show 4% of Red Yeast Rice is most preferred and considered to be most suited with flour and rice flour.
