The experiment was conducted to test the effects of ectomycorrhizal inoculation and soil moisture regime on growth and nutrient uptake of Pinus rigida seedlings. Two-year-old seedlings inoculated with either Pisolithus tinctorius or Thelephora terrestris were used for this experiment. There were two moisture treatments and four phosphate treatment levels with three replications. Height and root collar diameter growth and dry weight increase were measured and nitrogen, phosphorous, and potassium in the tissue were analyzed three months after the initiation of phosphate and moisture regime treatment. Results are as follows; 1) Height growth of seedlings was not affected in all treatments. (mycorrhizae, fertility, moisture). 2) High moisture regime increased root collar diameter growth 2.7 .times as large as low moisture regime. 3) In low moisture regime, net production increased 26% in seedlings inoculated with Pisolithus tinctorius and increased 72% control seedlings. 4) In high moisture regime, net production of inoculated seedlings with Pisolithus tinctorius increased four times as much as that of control seedlings but increased P₂O_5 in fertility level did not affect net production. 5) In uptake of nitrogen, phosphate, and potassium, Pisolithus tinctorius - inoculated seedlings increased uptake by 1.9, 1.8, and 1.5 times, respectively, as much as control seedlings. 6) Increase in P₂O_5 fertility level enhanced the uptake of P₂O_5 in Pisolithus tinctorius - inoculated seedlings, but not affected the uptake of P₂O_5 in control seedlings. 7) Increase in P₂O_5 fertility levels enhanced the uptake of K₂O in Pisolirhus rinctorius - inoculated seedlings.

Purpose: The purpose of this study is to understand family members' experience of deciding to withdraw life-sustaining treatments for terminally-ill patients in an unconscious state. Methods: Data were collected by performing an in-depth interview with eight terminally-ill patients' family members who decided to withdraw life-sustaining treatments. Colaizzi's phenomenological method was used for data analysis. Results: Questions were classified into 12 groups and finally into five categories. The five categories were about family members' frustration with patient's condition, emotional preparation for the patient's death upon medical professionals' recommendation, patient's wishes, exhaustion due to caring and past experiences related to life-sustaining treatment. Conclusion: Using the five categories, hospice and palliative professionals could better understand family members' decision making experience of withdrawing life-sustaining treatments for terminally-ill patients. Based on that, the family members could be provided with appropriate counseling and care, which in turn could improve hospice and palliative care intervention. 목적: 본 연구의 목적은 의식 없는 말기환자 가족의 연명치료 중단 결정 경험을 이해하기 위함이다. 방법: 자료는 의 없는 말기환자의 연명치료 중단 결정을 한 8명의 가족으로부터 심층면담을 통해 수집하였다. Colaizzi의 현상학적 분석 방법이 자료 분석을 위해 사용되었다. 결과: 주제는 12개의 주제모음으로 분류되었고, 12개의 주제모음은 마침내 5개의 범주로 통합되었다. 5개의 범주는 환자상태로 인한 절망감, 의료진의 권고에 마음을 비움, 환자의 바램, 돌봄으로 인한 가족의 소진, 연명치료와 관련된 과거의 경험이었다. 결론: 다섯 개의 범주를 통하여 의식 없는 말기환자 가족의 연명치료 중단 결정 과정에서 발생할 수 있는 현상들을 이해함으로써 적절한 상담과 간호를 제공하여 보다 바람직한 호스피스 완화의료 중재가 필요하다고 본다.

트레드밀 운동이 비만 쥐의 심장근 내 항산화에 어떠한 영향을 주는지 알아보고자 흰쥐에 6주 동안 고지방 식이로 비만을 유발시킨 뒤 운동강도와 적용시간을 달리하여 트레드밀을 3주 동안 적용하였으며, 체중변화, 혈중지질성분, 조직학적 변화, 심장근 내 항산화 효소와 MCP-1(monocyte chemoattractant protein-1) 등의 변화를 연구하였다. 4주령 Sprague Dawley계 수컷 흰쥐 32마리를 사용하여 각각 일반사료를 섭취한 정상군 (normal), 비만 대조군 (control), 비만 쥐에게 고강도 분할운동을 적용한 실험군 I(Experimental I), 비만 쥐에게 중강도 지구력 운동을 적용한 실험군 II (Experimental II)로 나누었다. 실험 결과 첫째, 체중변화는 고강도 분할 운동을 적용한 실험군 I과 중강도 지구력 운동을 적용한 실험군 II는 대조군에 비해 유의한 감소가 있었다 (p<0.001). 특히, 운동을 적용한 1주에서 3주까지 유의한 차이가 있었다. 둘째, 혈중지질성분 수치는 고강도 분할 운동을 적용한 실험군 I과 중강도 지구력 운동을 적용한 실험군 II는 대조군에 비해 총콜레스테롤, 중성지방, 저밀도 지단백질의 유의한 감소, 고밀도 지단백질에서는 유의한 증가가 있었다 (p<0.001). 셋째, 심장근의 조직학적 소견은 심장근에서 아교질 형성과 평활근 섬유의 정렬 상태와 밀집도, 심장근 세포크기가 중강도 지구력 운동 적용한 실험군 II에서 정상군과 비슷한 형태인 근육들이 잘 밀집해 있는 것을 볼 수 있었다. 또한, 섬유아세포, 염증세포들의 침윤 등이 고지방 식이 유발 쥐인 대조군과 고강도 분할 운동을 적용한 실험군 I에서 가장 심하였으며, 중강도 지구력 운동을 적용한 실험군 II는 대조군에 비해 섬유아세포, 염증세포들의 침윤 등이 현저히 감소하였다. 넷째, 심장근의 항산화 효소 SOD(superoxide dismutase), CAT(catalase), GPx(glutathione peroxidase) 수치는 중강도 지구력 운동을 적용한 실험군 II와 고강도 분할 운동을 적용한 실험군 I에서 모두 유의한 증가가 있었다 (p<0.001). 다섯째, 심장근의 항산화 단백질 MCP-1 발현 수치는 고강도 분할 운동을 적용한 실험군 I과 중강도 지구력 운동을 적용한 실험군 II 모두에서 감소가 있었으며 (p<0.01), 특히, 중강도 지구력 운동을 적용한 실험군 II에서는 유의한 감소가 있었다 (p<0.001). 따라서, 중강도 지구력 운동은 고지방 식이로 유발된 비만 쥐의 심장근 내 항산화에 영향을 주어 비만 개선과 산화적 스트레스에 의한 심장근육 손상 감소 등에 효과적인 것으로 나타났다. The aims of this study was to observed an effect of antioxidative in cardiac muscle of high fat diet induced obesity rat by treadmill exercise with intensity and time. Thirty-two Sprauge-Dawley rats which were divided into four group. Normal, Control(high fat diet induced obesity rat), Experimental I(high intensity intermittent exercise in high fat diet induced obesity rat), Experimental II(moderate intensity endurance exercise in high fat diet induced obesity rat). The results of this study were as follows: 1. In change of body weight, the outcome of each group significantly difference compared with control. Also, 1 to 3 weeks significantly different compared with pre valu experimental I and II(p<0.001). 2. In change of lipid profile, the outcome of each group significantly difference compared with control(p<0.001). Difference between experimental I and II is not significantly. 3. In change of antioxidative enzymes(SOD, CAT, GPx) in myocardium, there are significant difference between control and experimental II, and also between control and experimental I(p<0.001). 4. In change of antioxidative protein MCR-1, the outcome of each group significantly difference compared with control(p<0.01). Experimental II was most significantly difference than the other group(p<0.001). The above results suggest that treadmill exercise effectively reduced in fat. It would be considered that moderate intensity endurance exercise has an effects on improved antioxidative enzyme in cardiac muscle of high fat diet induced obesity rat.

The applications developing in distributed object computing enviroments are faced with the difficulties for managing various lots of distributed objects. Also, because the most multimedia service, like video, audio, and so forth, must be satisfied itself with real-time constraints, the users also are feeling with necessary to apply real-time mechanisms to distributed multimedia services. The goal of this paper is to solve the problems for managing distributed objects, and to be easy to develop complex applications that can provide real-time services. To do this, we designed and implemented a real-time object group platform that can be placed between applications and CORBA. This platform is extended the existing object group model[13,14] added to the scheduler and timer object components for supporting real-time concept. We designed the components for platform by using James Rumbaugh object modeling technology that consists of object, function, and dynamic model. And then we described the detailed interfaces of the components by IDL, and implemented our real-time object group's platform using OrbixMT 22 which is the IONA Technologies' ORB product. Finally, we showed the execution procedures of the schduler object of each components in a real-time object group platform.

Purpose: This study is a descriptive research which is designed to investigate hospitalized patients' intent to use home care nursing according to the types of medical security. Method: This researcher surveyed 236 patients who were hospitalized at B medical center located in Busan,. Data were collected from Sep. 1 to Nov. 30, 2005 using a questionnaire survey, medical records, face-to-face interviews and observations. Collected data were analyzed in terms of frequency, percentage, mean and standard deviation through $x^2$-test and t-test under SPSS WIN 10.0 Program. Result: Out of the total subjects, 59.3% were medical aid clients and the remaining 40.7%, health insurance ones. The hospitalized period and frequency of the former group were 38.0 days and 4.0 times, respectively, while those of the latter, 37.7 and 3.4. When home care nursing clients were examined using a given classification device, it was found that out of the total 236 subjects, 205(86.9%) were needed to receive home care nursing, 121, medical aid and the other 84, health insurance. 24.0% of medical aid clients heard about home care nursing ever before, lower than 39.3% of health insurance clients. 43.8% of the former clients said cost for home care nursing was high while, 47.6% of the latter group responded expense for the nursing intervention was low. 30.6% of medical aid clients had intent to use home care nursing, lower than 47.6% of health insurance clients. 71.7% of those patients whose monthly income was 99 million won or below had no intent to use home care nursing, higher than 62.5% of those who were 100 million or over in monthly income(p<.05). 76.4% of those clients who had no nursing provider intented to use home care nursing, higher than those who had nursing provider(p<.05). Concerning contents of home care nursing, 85.1% of medical aid clients needed education, training and counseling while, 77.4% of health insurance aids wanted medication and injection. Conclusion: In conclusion, the use of home care nursing by medical aid clients should be promoted through improving conditions for home care nursing in terms of expense, family and residence and making public relations about activities and contents of the home care nursing.

Dehydrocoupling of Bis(silyl)alkylbenzenes to Network Polysilanes, Catalyzed by Group 4 Metallocene Combination

김명희,이준,무수용,김종현,고영춘,우희권,Kim, Myoung-Hee,Lee, Jun,Moo, Soo-Yong,Kim, Jong-Hyun,Ko, Young Chun,Woo, Hee-Gweon The Basic Science Institute Chosun University 2010 조선자연과학논문집 Vol.3 No.1

Bis(silyl)alkylbenzenes such as bis(1-sila-sec-butyl)benzene (1) and 2-phenyl-1,3-disilapropane (2) were synthesized in high yields by the reduction of the corresponding chlorosilanes with $LiAlH_4$ in diethyl ether. The dehydrocoupling of 1 and 2 was performed using group IV metallocene complexes generated in situ from $Cp_2MCl_2$/Red-Al and $Cp_2MCl_2$/n-BuLi (M = Ti, Hf), producing two phases of polymers. The TGA residue yields of the insoluble polymers were in the range of 64-74%. The molecular weights of the soluble polymers produced ranged from 700 to 5000 ($M_w$ vs polystyrene using GPC) and from 500 to 900 ($M_w$ vs polystyrene using GPC). The dehydropolymerization of 1 and 2 seemed to initially produce a low-molecular-weight polymer, which then underwent an extensive cross-linking reaction of backbone Si-H bonds, leading to an insoluble network polymer.
