박인철,이판종,양지원,김종득,최태부,Park, In-Chul,Lee, Pan-Jong,Yang, Ji-Won,Kim, Jong-Deuk,Choe, Tae-Boo 한국미생물 · 생명공학회 1994 한국미생물·생명공학회지 Vol.22 No.3
Micelle, liposome and polyethylene glycol(PEG) were employed to reduce the cell mem- brane toxicity of Amphotericin B(Amp. B). Cholesterol-sulfate which can form a mixed micelle with Amp. B molecules was found very effective for the reduction of Amp. B toxicity. 0.01% of cholesterol-sulfate could reduce the toxicity of 5X 10$^{-6}$ M Amp. B by 90%. The required concent- ration of cholesterol-sulfate for the toxicity reduction was proportionally increased with increasing Amp. B concentration. PEG was also effective on the reduction of Amp. B toxicity. 2% PEG was required for the reduction of toxicity by 50%, regardless of Amp. B concentration. The liposome system showed an effective reduction of Amp. B toxicity on RBC, maintaining the antibiotic effect on Candida albicans as free drugs. This seems to be due to the fact that liposome bilayer plays a role of buffer system between ergosterol of fungi cell membrane and cholesterol of red blood cell membrane, which leads the redistribution of Amp. B between them, as the result, the reduction of drug toxicity on cell membrane.

FBAR(Film Bulk Acoustic Resonator) 소자의 공진특성을 결정하는 가장 중요한 요소는 압전막의 압전성을 들 수 있다. FBAR 압전막으로 유력한 ZnO 압전박막은 (002)면 c-축 우선배향성(preferred orientation)의 정도에 따라서 압전성이 결정된다. 그러므로 ZnO 박막의 우선배향성에 관한 연구는 많은 연구자들의 관심사가 되어왔다. 본 논문에서는 ZnO 보조씨드충(helped seed layer)을 이용하여 ZnO 압전박막의 우선배향성에 대하여 조사하였으며, rocking curve의 표준편차$(\sigma)$ 값이 $1.15^{\circ}$인 주상형 결정립을 가진 c-축 ZnO 압전박막이 우수한 압전특성을 나타내는 것을 확인하였다. The most important factor which determines resonance characteristics of FBAR(Film Bulk Acoustic Resonator) is the piezoelectricity of piezoelectric film. The piezoelectric properties of ZnO thin films which is strong as FBAR piezoelectric film is determined by the degree of c-axis preferred orientation with (002) plan. Therefore, many researchers have been interested in the study on the preferred orientation of the piezoelectric thin film. This paper has studied the preferred orientation of ZnO piezoelectric thin films using the helped seed layer of ZnO. The result shows that the c-axis ZnO thin films with columnar grains that the value of standard $deviation(\sigma)$ of XRD rocking curve is of $\sigma=1.15^{\circ}$ have the excellent piezoelectric property.

Purpose: The purpose of this study is to analyze the problems of the home welfare services and to provide the suggestion for improvement plan of these services. Methods: A literature review was used to perform this study, which included a field study carried out in Korea. Results: The problem of the home welfare services were identified as follows, The criteria for the beneficiaries are not clear, the programs are not customized to meet beneficiaries needs, the separation of the departments and administrative organizations, and poor financial support, The improvement plans to solve these problem were recommended as follows. First, the criteria to select senile people should be modified in terms of qualitative and quantitative aspect. Second, professional customized services should be extended to the home based senile people suffering from various disease, Third, it is desirable to enhance the rehabilitation service for the aged, Fourth, it is necessary to operate integrated home welfare services, Fifth, it is necessary to solve the financial difficulties through integrated service networks, Conclusion: The ultimate goal of home welfare services for senile people may lie in protection of community or social integration Just beyond the simple welfare services.

본 논문은 차량용 스마트에어백 시스템이 탑승자의 머리 위치를 파악하여 지능적으로 에어백을 전개하도록 돕기 위한 얼굴 위치 검출 알고리즘을 제안한다. 차량용 임베디드 시스템은 한정된 자원에서 기능을 동작시키기 때문에 여러 가지 구현상 제한 조건들이 존재한다. 이러한 제한 조건들을 만족시키기 위해 알고리즘의 경량화 및 최적화 작업이 수반 되어져야한다. 제안하는 알고리즘에서는 이진화 된 오브젝트에 거리변환(Distance Transform)을 사용하여 사람의 형태학적 모양을 분석/판단한다. 그리하여 얼굴의 위치를 검출하는 방법이다. 여러 가지 배경 상황에 관계없이 사람의 형태학적 모습을 이용하므로 사람 형태 검출에 용이하다. 설계된 알고리즘은 TI사의 TMS320DM6437 EVM 보드에서 구현하였고 구현 결과 제안한 알고리즘이 IR 영상에서 높은 인식률 및 빠른 처리 속도를 보임을 확인할 수 있었다.

As people`s interest about wildlife animal increases, more wildlife animal centers are developing. In South Korea, currently 120 mammal species live, and 22 of them are designated as endangered species. It is important to protect these natural treasures and endangered species, because they are being harmed by human industrial activity. For example, road expansion and poaching have led to the destruction of wildlife animal habitats, which is increasing year by year. Nevertheless, data regarding the systematic treatment of wild animals that are in distress is lacking, and it is a reality that analysis of such data is also lacking. The Kangwon Wildlife Rescue Center investigates these types of distress experienced by mammals. By analyzing the shape of the wild animals killed or injured, the center seeks an efficient and systematic way to manage such distress. The data collected from the Wildlife Animal Center from September 2007 to August 2010 includes 195 different cases, and the animals point of rescue. There are 16 species, including 87 water deer (Hydropotes inermis), 39 raccoons (Nyctereutes procyonoides), 20 roe deer (Capreolus pygargus bedfordi), 10 goral (Nemorhaedus goral), 7 siberian weasels (Mustela sibirica), 6 otters (Lutra lutra) and etc. Within the first year (September 2007 to August 2008), the number of mammals rescued was 46. In the second year (September 2008 to August 2009), 60 animals were rescued. in the third year (September 2009 to August 2010), the Wildlife Animal Center had 89 animals. We can see that these numbers are increasing, which shows that people are interested in the well-being of these animals because they are reporting animal injuries more and more. The mains form of distress caused by humans are from car accidents 67 (34.4%). Traps, and other hunting tools used by poachers are responsible for 25 (13.0%). Also, human industrial activity thus indirectly led to the starvation 25 (13.0%). and the orphaning of young animals 37 (19.0%).

This survey aims to provide information on the pattern of distress in wild avian animals in Gangwon province. This survey is based on 315 wild avian which were rescued by the Kangwon University Wildlife Rescue Center. The data was collected at the Wildlife Animal Center from September 2007 to August 2010, and by analyzing the shape of the wild animals killed or injured, the center seeks an efficient and systematic way to manage such distress. There are 55 species found, in this study including 40 common kestrel, 34 eurasian eagles, 20 common buzzards, 20 collared scops owls, 19 oriental scops owls, 16 brown hawk owls and 160 others. These are the results of the survey: 129 (40.3%) of 315 avian birds were found between June and August. Many cases in that term were observed falling from the nest or losing their mother because of unskilled flight during the breeding season`s flight practicing process. Between November and December, 64 individual (20.3%) were found, and it`s the second largest number. The main reasons for these results were starvation and exhaustion from the winter migratory season. The results indicated that the main reason for avian distress came from the following: collision with architecture windows in 73 cases (23.2%), starvation and exhaustion in 63 cases (20.0%), collision with vehicles in 51 cases (16.2%), becoming orphaned in 69 cases (21.9%), trespassing into buildings occurred in 19 cases (6.0%), collision with electric wires in 18 cases (5.7%), poaching materials in 13 cases (4.1%), becoming entangled by fishing wire and other miscellaneous materials in 4 cases (1.3%), infection from parasites in 4 cases (1.3%), toxicosis from such toxins like agricultural chemicals in 1 case (0.3%). Overall, the purpose of this investigation was to analyze cases of avian distress in Korea`s wildlife. This study used areas, seasons and causes to understand origins of these animals distress. So that it can be utilized for organized wild avian rescue and treatment.
