趙三來,金賢泰 공주대학교 사범대학 과학교육연구소 1992 과학교육연구 Vol.23 No.1

Mallards(Anas platyrhynchos) and Green-Winged Teal(anas crecca) were studied at Kum River, Kongju, Korea, from 29, December, 1990 to 5, Janury, 1991. There was a wide difference between Mallards(Anas platyrhynchos) and Green-Winged Teal(Anas crecca) in body length but used to same Resting or Feeding area. Resting time was the major activity of mallards(43-45%) and Feeding time was the major activity of Green-Winged Teal(30-34%). Both species increased Resting time as approach of sunset but Locomotion and Comfort decreased. Locomotion(22-24% and 16-24%) and Comfort(16-21% and 14-22%) also were dominant behavioral activities of Mallards and Green-Winged Teal, respectively. Total time spent in Alert, Courtship and Agnoistics behavior was low for both species(>3%). Mallards and Green-Winged Teal rested most on sand bar in River side, while paddy fields were used most for feeding area.

This paper introduces trust measurement that is composed of trust variables and fuzzy cognitive map. The improved trust measuring method using a stratified FCM can be used to measure the level of risk involved in a specific auction transaction concerned. To reduce the auction transaction cost and time, the proposed system recommends a differentiated transaction protocol according to the risk based on trust measurement. In this system, trust measurement can also be applied for differentiated and varied auction services.

본 연구는 교통사고 장기입원 환자와 그 가족들의 재적응과 관계가 있는 심리사회적 요인들을 파악하고, 이를 바탕으로 하여 교통사고 환자들의 치료 및 재활을 돕기 위한 개선책을 제안하는 것이 주 목적이다. 연구 대상은 최소한 2개월 이상 입원 중인 교통사고 환자 56명과 그 보호자(주로 가족)들이었다. 측정 도구로는 본 연구의 목적에 맞게 제작한 면접지와 함께 간이정신진단검사(SCL-90-R),Katz적응척도(KAS)및 외성영향척도(IES)등을 사용하였다. 연구 결과를 요약하면 다음과 같다. 간이정신진단검사 결과, 상당수의 환자들이 심리적 문제(특히 공포나 불안)을 호소하고 있었다. 이러한 심리적 문제들은 신체손상집단보다 두부 및 신체손상집단에서 더 두드러지게 나타나고 있다. 환자들은 현재 상황에 대한 지각 및 가정생활에 대한 만족도, 그리고 여러 장애들에 대한 통제지각 및 예후에 대한 기대가 부정적이었고, 절망적인 태도를 보이고 있다. 특히 사회적 활동에 대한 기대가 부정적이었고, 그 다음은 신체적 손상이었다. 보호자들도 환자들과 마찬가지로 환자의 장래 적응에 대해 비관적일 뿐 아니라, 그들 스스로도 가계의 운영및 가정 생활의 만족도에서 어려움을 겪고 있었다. 기혼부부의 경우에는 교통사고 이후 성생활에서 불만을 많이 겪었다. 교통사고 환자들은 가족들에 대해서는 전반적으로 높은 지지감을 느끼고 있으나, 사고 관련기관에 대해서는 극히 부정적인 시각을 드러냈다. 응급조치의 지연과 불충분한 응급조치 등 교통사고 장기입원 환자들에 대한 치료과정에 여러 문제들이 있었다. 현재 환자들이 받고 있는 치료에 대해 갖는 주된 불만 요인으로는 "치료를 제대로 못받고 있다"는 것과, "치료의 호전이 없다'는 점 외에도 "환자의 상태에 관해 잘 이야기해 주지 않는다"는 것이 주목할만 하다. 마지막으로, 본 연구에서 밝혀진 치료과정에서의 문제점을 개선할 수 있는 몇가지 방안들을 제시하였다. Adjustment Scale, and the Impact of Event Scale. The results are as follows. (1)The percentage of inpatients who reported clinically significant psychological problem was 18.2% in the global severity index of SCL-90-R,, especially 20.0% in anxiety and 32.6% in phobic anxiety. These problems were severer in body-injured inpatients with head injury than i body-injured inpatients without head injury. (2)TA inpatients were very pessimistic and hopeless in the perception of current situations, the degree of satisfaction at family life, and the perceived control and the expectancy of prognosis of various disorders, especially difficulties in social activites and somatic injury. Likewise, their caretakers(mainly family members) not only had difficulties in home management, but also showed pessimistic attitude toward the inpatients' future adjustment and the satisfaction at family life (3)TA inpatients in general felt that their family members were highly supportive, but that the institutions concerned with TA were not supportive. Whereas they on the average perceived that their treating staff(medical doctors and nurses) were supportive, they individually expressed dissatisfaction toward them. (4)In the treatemtn processes of TA inpatients, many problems were found. As for emergency treatment, rapid and sufficient intervention had not been taken. Also, long-term TA inpatients and their treatments due to several reasons. Finally, some suggestions for improving the treatment processes described above were provided.

Heterogeneous nucleation in the polyol process for the synthesis of FeCo alloy powders

Cho, Uk Rae,Lee, Dong Gun,Ahn, Byung Hyun,Lee, Je Hyun,Koo, Bon Heun Korean Physical Society 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.64 No.10

Here, we report a polyol method to prepare monodispersed FeCo alloy particles with Pt seeds added in the production of nanoparticles. The prepared samples were characterized by using X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and magnetic measurements. Structural studies revealed that the FeCo nanoparticles had a body-centered cubic (BCC) structure. FE-SEM analysis demonstrated a sphere morphology for the FeCo alloy particles. The size of the FeCo nanoparticles could be well tuned by changing the number of Pt-seed partices in the FeCo alloy. The magnetic properties of the FeCo alloys were investigated as a function of the Pt-seed concentration and temperature. The saturation magnetization and coercivity of the FeCo nanoparticles were found to depend on the molar ratio of Fe/Co, as well as the number of Pt-seeds, and increased with increasing FeCo concentration. A higher value of the saturation magnetization, 218 emu/g, was obtained for the 0.07-M concentration of FeCo alloy. In the process of producing an FeCo alloy powder by heterogeneous nucleation, a powder having minute sizes could be produced under the experimental conditions of a Pt-seed-added temperature of 90 A degrees C and a Pt/FeCo mole ratio of 8 x 10(-5), and showed far superior properties.

Cho, Eun Sook,Jin, Byung Rae,Sohn, Hung Dae,Choi, Kwang Ho,Kim, Soung Ryul,Kang, Seok Woo,Yun, Eun Young,Kim, Sang Hyun,Kim, Keun Young,Je, Yeon Ho,Kang, Seok Kwon 한국잠사학회 1998 한국잠사곤충학회지 Vol.40 No.2

To construct transfurmed Bm5 cells, Autographa californica nuclear polyhedrosis virus(AcNPV) IE1 gene, an immediate early viral gene was firstly used in this study. AcNPV IE1 gene, which shares on 95.3% nucleotide sequence homology with Bombyx mori nuclear polyhedrosis virus (BmNPV) IE1 gene, was isolated and cloned into pBluescript. Neomycin gene from pKO-neo was inserted under the control of the IE1 promoter to yield pAcIE1-neo. The plasmid pAcIE1-neo was transfected into Bm5 or Sf9 cells, and neomycin-resistant cells were selected in TC100 medium containing 10% fetal bovine serum (FBS) and 1 mg/ml G4l8 for two weeks. Individual clones were picked and each was amplified for further characterization. The genomic DNA from neomycin-resistant cells was isolated and characterized by PCR using AcNPV IEI gene-specific primers and by Southern blot analysis using neomycin gene probe. We concluded that AcNPV IE1 gene was functional in B. mori-derived Bm5 cells as well as Spodoptera fugjprrda-derived Sf9 cells to produce stably-transformed insect cells

The present study was to assess the in vitro viability and sexing rate of bovine embryos. Blastocysts were harvested on day 7~9 day after insemination(in vitro and in vivo), and the sex of the embryos was examined using the LAMP method. Embryo cell biopsy was carried out in a $80{\mu}l$ drop $Ca^{2+}$, $Mg^{2+}$ free D-PBS and, biopsied embryos viability were evaluated after more 12 h culture in IVMD culture medium. The formation of recovered embryo to expanded and hatching stages had ensued in higher of sexed embryo in vivo than in vitro (100% vs. 89%, p<0.05), and in vitro, the rates of degeneration after sexing were significantly (p<0.05) higher in vitro than in vivo(11% vs. 0.0%). The rates of the predicted sex were female 61% vs. 56%, and male 39% vs. 44% in vivo and in vitro, respectively. The rates of survival following different biopsy methods were seen between punching and bisection method in vivo and in vitro (100% vs. 89% and 100% vs, 78% respectively). Biopsy method by punching was significantly (p<0.05) higher than bisection between produced embryos in vivo and in vitro. The present data indicate that with microblade after punching for embryo sexing results in high incidence of survivability on development after embryo biopsy. It is also suggested that LAMP-based embryo sexing suitable for field applications.

Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease characterized by dry skin with severe itching Children with AD and their caregivers report itching, scratching, associated sleep disruption, irritability, anxiety, behavior problems. Moreover, AD places a significant economic burden on the patient, family and society. So, an integrated health care service can be useful to comprehensively evaluate triggers and response to treatment, address confounding factors including psychological problems, and educate patients and family. This study was designed to evaluate the effectiveness of integrated health care service in children with AD according to quality of life and clinical symptoms scores. From July, 2011 to December, 2011 134 children were referred from local health care office to Seoul Medical Center for management of atopic dermatitis. The questionnaire developed by the ``Atopy Free Seoul`` research project in 2008 was used for quality of life (QOL) survey, and SCORing of Atopic Dermatitis (SCORAD) was done at each visit. The study targets were 134 child patients with the average age of 6.11 years who suffer from atopic dermatitis and visit the hospital 2.01 times on average. It was found that the QOL scores of patients participated in our integrated health care service was reduced by 10.43 after treatment compared before intervention (p<0.0001). In 46 children among them, SCORAD also averagely decreased by 5.78 after treatment (p<0.0001). Moreover there is positive correlation between changes in scores of QOL and SCORAD of 46 patients (r=0.46, P<0.001). This results support the need for and feasibility of integrated care for children with AD and their families.
