장혜숙,김순애,김흥규,Jang Hye Sook,Kim Soon Ae,Kim Hung Kyu 한국아동간호학회 1999 Child Health Nursing Research Vol.5 No.1
This study was designed to determine the schemata and their characteristics of stress experience the subjectivity of stress experience(structure of subjectivity) would be a basic step for the effective clinical education through the stress management for characteristics of these types. Q-methodological method was used for that purpose. The research method statements were collected prior to the study through indepth interviews. For the study, 31 Q-statements were selected. There were 34 nursing students as subjects for the research. The 34 nursing students sorted the 31 statements using the principal of forced normal distribution. The principle of forced normal distribution, which has 9 scales to measure the individual opinions, was called. Q-factor analysis by using PC QUANL program supply the material. According to the outcomes of this study, there were 3 types of special opinion about the stress experience of clinical practice. The first type is called 'Influence of practical atmosphere type'. Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The second type is called 'conflict of nursing role type'. Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The third type is called 'Lack of confidence type'. Members of this type experienced stress because of a lack of confidence for their own nursing knowledge and skill. As a result, we now need further study to identify individual psychological aspects of stress for clinical practice. The findings will guide the development in effective approaches for clinical education. Finally, the result of the study will provide us the need for developing systematic and integrated practice education program for students and active involvement of clinical instructor.

This study was conducted to compare the anesthetic effects of intravenous tiletamine-zolazepam(TZ, 7mg/kg TZ), tiletamine-zolazepam-xylazine(TZX, 7mg/kg TZ and 1.1mg/kg X) and ketamine-xylazine(KX, 10mg/kg K and 1.1mg/kg X). Fifteen mixed-breed healthy dogs($3.5{\pm}1.0kg$) were randomly assigned to the three treatment groups(TZ, TZX, KX) with 5 dogs in each group. The mean surgical anesthesia time was $25.6{\pm}4.2$, $62.6{\pm}6.2$ and $21.0{\pm}3.7$ min in TZ-, TZX- and KX-anesthetized dogs, respectively. The duration of the loss of response to toe-web needle prick and to visceral pain was significantly increased in the TZX group with $40.0{\pm}15.8$ min and $44.0{\pm}5.5$ min, respectively(p<0.01). Heart rate decreased significantly below baseline in TZX and KX groups(p<0.05, p<0.01) whereas it increased above baseline in TZ group. Respiratory rate remained unchanged or increased above baseline in TZ group, but decreased significantly from 10 to 30 min in TZX(p<0.01, p<0.05) and at 10 min in KX group(p<0.05). Body temperature decreased significantly below baseline in all three groups(p<0.01, p<0.05). Hematologic(PCV, RBC, WBC) and serum chemistry values(GOT, GPT, BUN, creatinine, total protein, glucose) were monitored before anesthesia, after recovery from anesthesia and 1, 3 and 7 days postanesthesia. All hematologic values remained generally within normal ranges, and GOT, GPT, BUN, creatinine and total protein values were within normal ranges during the period. Glucose values for TZX and KX groups increased greatly after recovery from anesthesia. We conclude that tiletamine-zolazepam-xylazine provides effective surgical anesthesia in dogs and in many cases may be preferable to conventional ketamine-xylazine regimen.

본 연구는 실내에 식물을 보다 효율적으로 도입하고자 수경재배 시 첨가매질(게르마늄, 맥반석)이 관엽식물의 생장과 잎의 무기성분, 뿌리활력에 미치는 영향을 구명하기 위하여 수행되었다. 싱고니움(Syngonium podophyllum), 드라세나 산데리아나(Dracaena sanderiana), 스킨답서스(Epipremnum aureum) 및 아이비(Hedera helix)를 식물재료로 사용하였으며 토양(혼합된 상토: Sunshine Mix No. 2, USA), 수돗물, 수돗물에 게르마늄(300g), 수돗물에 맥반석(300g)을 첨가하여 정식하였다. 첨가매질에 따른 생육변화는 싱고니움의 경우 수돗물만 처리한 구에서 가장 저조하였고 게르마늄 첨가구에서 생육이 가장 좋았으며, 드라세나 산데리아나는 처리구에 따른 생장의 차이가 거의 없는 반면, 스킨답서스와 아이비의 생장도 게르마늄 첨가구에서 가장 좋았다. 특히 뿌리의 생장에서 커다란 차이를 보였는데 근장, 근수 및 근중이 게르마늄 첨가구에서 가장 좋았다. 뿌리활력은 10일 간격으로 분석하였는데 작물마다 처리구에 따라서 변화가 있었는데 싱고니움의 경우 10일째는 3처리구 다 뿌리활력이 낮아졌으나 차츰 좋아져 30일과 50일째에는 맥반석 첨가구에서 가장 좋았다. 드라세나의 경우 10일째부터 40일 째까지 게르마늄 첨가구에서 가장 좋았으나 50일째부터 뿌리활력이 나빠졌다. 그러나 60일 후에는 처리구간 큰 차이가 없었다. 식물체 잎의 무기성분 분석 결과, 게르마늄의 Ca과 Mg 함량이 맥반석 보다 높았지만 잎의 무기성분 함량에는 영향을 미치지 않는 것으로 나타났다. 이상의 결과에서 스킨답서스와 아이비는 배지재배보다 수경재배에서 생장이 좋았고, 수경재배시 수돗물에 게르마늄을 첨가하였을 때 생육이 증가하는 것으로 나타났다. This research was conducted for the purpose of investigating the influence substrates addition such as germanium or Granite porphyry gravel have on the growth of foliage, on the inorganic compositions of leaves as well as on root activity, in order to discover effective means of introducing plants to the indoors. Syngonium podophyllum, Dracaena sanderiana, Epipremnum aureum and Hedera helix were used as study subjects to which soil (mixed top-soil: Sunshine Mix No. 2, USA), tap water, tap water with germanium (300g), tap water with Granite porphyry gravel (300g) were added respectively and formulated. Studies on growth variations according to substrates addition indicate that growth of Syngonium podophyllum was most sluggish under tap water only treatment. Plant growth was most active under geranium-gravel treatment. In the case of Dracaena sanderiana, treatment of substrates addition had no meaningful influence on plant growth. However, the growth of Epipremnum aureum and Hedera helix was also shown to be most active under geranium-gravel treatment. Geranium-gravel treatment was shown to be particularly beneficial for root length, number of roots and dry weight. Root activity was analyzed on ten day intervals and there was discernable difference in the root activity of all the plants according to the varying treatments. In the case of the Syngonium podophyllum, the root activity was sluggish in all three types of treatment on the 10th day but improved gradually. On the 30th to the 50th day of the experiment, the root activity was found to be best under the Granite porphyry gravel treatment. In the case of the Dracaena sanderiana, the root activity was most active under the geranium-gravel treatment from the 10th to the 40th day but deteriorated from the 50th day. However, there was no significant different in all three treatments from the 60th day onwards. Analysis of the inorganic components of the leaves indicates that, while Ca and Mg were higher in the geranium than in the Granite porphyry gravel, they do not directly influence the content of inorganic components in the leaves. The results indicate that Epipremnum aureum and Hedera helix grow better under hydro-culture than when grown in soil and growth under hydro-culture is shown to increase when germanium is added to tap water.

Fiber-reinforced polymer reinforcement or polyurea reinforcement techniques are applied to strengthen unreinforced masonry walls (UMWs). The out-of-plane reinforcing effect of sprayed glass fiber-reinforced polyurea (GFRPU), which is a composite elastomer made of polyurea and milled glass fibers on UMW, is experimentally verified. The out-of-plane strengths and ductile behaviors based on various coating shapes are compared in this study. An empirical formula to describe the degree of reinforcement on the out-of-plane strength of the UMW is derived based on the experimental results. It is reported that the peak load-carrying capacity, ductility, and energy absorption capacity gradually improve with an increase in the strengthening degree or area. Compared with the existing masonry wall reinforcement method, the GFRPU technique is a construction method that can help improve the safety performance along with ease of construction and economic efficiency.
