  • 본 논문은 현행 환경평가 제도가 평가 대상을 규모 기준으로 규정함으로써 발생되는 비효율성을 개선하기 위해 스크리닝의 도입을 통한 환경평가 절차 효율화 방안을 제안하였다. 대상사업은 환경적 영향이 미미한 소영향 사업으로 한정하였다. 우선, 국내에서 추진되었던 절차 효율화 사례 등을 살펴보고 그 특징 및 한계점을 도출하였다. 또한 사업의 특성 및 환경적 영향을 고려하여 후속 환경평가 실시여부와 그 정도를 개별적으로 판단하는 평가 대상 선별과정인 스크리닝의 국내 도입 가능성을 검토하였다. 외국의 스크리닝 제도 및 그 시사점 분석을 통해 국내 적용 가능한 스크리닝 도입 시나리오 제시를 통해 절차 효율화를 도모하고자 하였다. 소영향 사업들에 대해 환경평가 현황 및 소영향 사업들의 특징을 분석하여 스크리닝의 도입 필요성과 가능성을 확인한 후 절차 효율화 방안을 제시하였다. 본 연구에서 제안하는 개선 방안은 소영향 사업에 대해 환경영향평가 실시를 면제하여 줄 수 있는 스크리닝 절차의 도입이다. 이는 규제완화의 효과 및 평가기간과 협의기간의 단축을 기대할 수 있다. 또한, 사업자들에게 스크리닝을 통한 평가절차 간소화 기회를 제공하여 계획 초기 단계에서부터 친환경적 계획 수립을 위해 노력하도록 유도하여 계획기간의 단축까지 기대할 수 있다. 즉, 사업자의 자율적인 노력을 도모하고 스크리닝으로 평가 절차를 생략하는 대신 저감대책 반영 여부에 대한 승인기관의 확인을 강조하여 사업자와 승인기관의 책임의식을 강화시킬 수 있는 방안이 될 수 있다.

  • AC Losses for face to face stacks of four identical coated conductors (CCs) were numerically calculated using the H-formulation combined with the E-J power law and the Kim model. The motive sample was the face to face stack of four 2 mm-wide CC tapes with 2 ${\mu}m$ thick superconducting layer of which the critical current density, $J_c$, was $2.16{\times}10^6A/cm^2$ on IBAD-MgO template, which was suggested for the mitigation of ac loss as a round shaped wire by Korea Electrotechnology Research Institute. For the calculation the cross section of the stack was simply modeled as vertically aligned 4 rectangles of superconducting (SC) layers with $E=E_o(J(x,y,t)/J_c(B))^n$ in x-y plane where $E_o$ was $10^{-6}$ V/cm, $J_c$(B) was the field dependence of current density and n was 21. The field dependence of the critical current of the sample measured in four-probe method was employed for $J_c$(B) in the equation. The model was implemented in the finite element method program by commercial software. The ac loss properties for the stacks were compared with those of single 4 cm-wide SC layers with the same critical current density or the same critical current. The constraint for the simulation was imposed in two different ways that the total current of the stack obtained by integrating J(x,y,t) over the cross sections was the same as that of the applied transport current: one is that one fourth of the external current was enforced to flow through each SC. In this case, the ac loss values for the stacks were lower than those of single wide SC layer. This mitigation of the loss is attributed to the reduction of the normal component of the magnetic field near the SC layers due to the strong expulsion of the magnetic field by the enforced transport current. On the contrary, for the other case of no such enforcement, the ac loss values were greater than those of single 4cm-wide SC layer and. In this case, the phase difference of the current flowing through the inner and the outer SC layers of the stack was observed as the transport current was increased, which was a cause of the abrupt increase of ac loss for higher transport current.

  • 소아치과 임상에 있어서 교정용 밴드는 매우 다양한 용도로 일상적으로 사용되고 있다. 그러나 교정용 밴드와 치아 사이에 시멘트가 불균일하게 분포되어 치아 법랑질 탈회나 치은염이 유발됨을 간혹 보게 된다. 본 연구는 이러한 문제를 근원적으로 차단할 수 있는 균일한 시멘트 층을 유지 한 밴드 장착방법을 모색할 목적으로 시도되었다. 발치된 상하 제 1 대구치를 복제한 치아모형에 이에 적합한 교정용 밴드를 선택하여 접착용 시멘트로 세 가지 방법으로 접착시켰다. 방법 1에서는 접착용 시멘트를 밴드 내면에만 도포하였고, 방법 2에서는 접착용 시멘트를 밴드 내면과 치아의 축면에 도포, 방법 3에서는 접착용 테이프를 밴드의 상연에 부착한 상태에서 밴드 내면에 접착용 시멘트를 도포하였다. 접착용 시멘트가 경화된 후 밴드를 치아에서 벗겨내고 내면의 시멘트 분포상태를 관찰하였다. 실험 결과, 밴드 내면에만 시멘트를 도포한 방법 1의 경우보다는 방법 2와 3의 경우에 시멘트가 더 균일하게 도포된 것으로 나타났다. 따라서 교정용 밴드를 장착하는 과정에서는 접착용 시멘트를 밴드 내면에만 도포하는 방법보다는, 치면에도 시멘트를 가하거나 잉여 시멘트의 교합면측 탈출구를 봉쇄하는 등의 방법이 균일하게 도포된 시멘트 접착을 달성하는 좋은 대안이 될 것으로 판단되었다.

  • Cardiac catheterization is a diagnostic procedure which is intrusive and anxiety provoking. Patient education and information offer have been suggested as effective nursing interventions to reduce patients' anxiety and stress. Main objectives of this study are : 1) to develop concrete objective information for patients undergoing cardiac catheterization : 2) to analyze the types of information included in the newly developed concrete objective information. The subjects of this study are 11 patients who were admitted to the CCU of a general hospital in Seoul. The subjects were provided with preparatory information about cardiac catheterization by using interview and a booklet. After the procedure, the subjects were asked to describe additional information which they suggest to be added into the booklet and the physical sensations felt during the procedure. The results of the study are summarized as follows : Most subjects were satisfied with the preparatory information that was provided by interview and the booklet before the procedure. But patients suggested several problems related to the content of the booklet. First, they reported difficulty to differentiate the terms -coronary angio gram and cardiac catheterization. Also, some patients expressed that they feared after reading the information about the incision of inguinal area. Subjects responded that the information about the direct process of the test did not reduce their anxiety and the information was not detail enough. Next, most subjects would want to know about the monitor and the sound from monitor. They said that they could not hear instructions from doctor or nurse during the procedure due to tension. Considering above response results, the need for more effective way to provide information, like visual and auditory information through video tape for giving information is suggested. Sensations related to the procedure were the smell coming from sterilization of inguinal area, stinging pain in groin when the doctor inserts a needle into artery, and the sensation of pressure and moving of vessels surrounding neck when the catheter was inserted and visualized on fluoroscopy. Besides, subject reported hot sensation and burning feeling in face and chest area, and nausea when dye is injected by hand. In the analysis of information content, there was 79% agreement on the actual units of analysis that were coded. In the analysis of type of information, procedural information was 60.4%. Concrete objective information was 28.1%. and other information was 11.5%. Agreement of the coders in categorizing the units of information was determined by using Cohen's kappa which corrects for chance agreement. Cohen's kappa was .84.

  • The purpose of this study was to construct a grounded theory as the basis for nursing intervention by describing and analysing the holistic lived experiences of clients receiving long-term hemodialysis. The subjects of this study were fifteen persons receiving regular hemodialysis regimen at artificial kindey treatment centers in two different university hospitals, and who were able to participate in conversation and were available for long and dup interviews. Eight of the subjects were male and seven were female and their ages ranged from 30's to 60's. The length of the hemodialysis experience ranged from two months to six years. The collection and analysis of data were done in accordance with the grounded theory methodology of Strauss & Corbin. The method to collect the data mainly depended. on long and deep interviews, participant observation and focused group interviews and the equipment used to collect data were a portable tape recorder and field notes. The study is summarized as follows : 1. The meaning of holistic lived experiences of clients receiving long -term hemodialysis was found to be uncertainty. which was identified as the core category. 2. The main categories following the core category were found to be shock, ambiguity, social support and quality of life. 3. Through the main category the type of behavior newly formed by clients receiving long-term hemodialysis was found to be as follows. That is to say, in the circumstances of shock caused by the identified fact and the ambiguity of hemodilysis they formed a quality of life based on social support, which was found to be a kind of chaotic phenomenon. 4. The lived experiences of clients receiving long-tern hemodialysis was found to include nine categories : emotional shock, feelings of isolation, burden, unclearness, dependency, help from others, coping strategies, maintenance of self-esteem and transitional life. 5. The intervening factors influencing each category are as follows : 1) The factors influencing 'emetional shock' were found to be set age, the level of knowledge received in advance, locus of control, the period of struggle against the disease before hemodialysis and whether any serious illness existed. 2) The factors influencing 'feelings of isolation' were found to be religion and the length of the hemodialysis experience. 3) The factors influencing 'burden' were found to be sex, economic situation, employment status and the length of the hemodialysis experience. 4) The factors influencing 'unclearness' were found to be sex, age, religion. economic situation, the length of the hemodiaysis experience, whether they had had a transfusion and whether there were any complications. 5) The factors influencing 'help from others' were found to be religion. economic situation, past experiences and whether family members lived together. 6) The factors influencing 'coping strategies' were foung to be age, level of education, experiences of illness and locus of control. 7) The factors influeruing 'maintenance of self-esteem' were found to be the length of the hemodialysis experience and self-actualization. 8) The factors influencing 'transitional life' were found to be age, religion, economic situation, employment status. locus of control. past experiences and whether there was a plan for a kidney transplant.

  • The purpose of this study was to evaluate the effects of the mandibular retractive force on the mandibular condyle of growing dog. The experimental animals were six mongrel dogs of two-month old. Their deciduous dentition were completed. Two of them was used as control group, and experimental group was composed of remaining four. Head band and chin cup were made of cotton tape, and hooks are fabricated on the chin cup and had band for closed coil. Mandibular retractive force was 100g/side and chin cap appliance was used for 14 hours/day during night. Experimental group were sacrificed at 2, 4, 6, 8 weeks from beginning of the experiment. Right TMJ was prepared for histologic study and left TMJ was examined grossly for disc, fossa, and condyle. The conclusions are: 1. Two-month old control animal showed active cartilaginous growth on the mandibular condyle, therefore showed thick proliferative and hypertrophic zones. Remodeling process in the condyle head was observed in which there were bone resorption on the anterior surface and bone apposition on the posterior surface. 2. Four-month old control animal showed marked reduction of hypertrophic zone but the condylar bone remodeling was more pronounced. 3. In experimental group, there are marked reduction of hypertrophic zone at 4 weeks from beginning of experiment, and hypertrophic zone disappeared at posterior-superior portion of condyle in 6-week experimental animal. 8 week experimental animal showed slight recovery of hypertrophic zone. 4. In experimental group, bone deposition was increased at anterior surface of condyle, and bone resorption was increased at posterior surface of condyle. 5. In control group, the glenoid fossa and surrounding bone showed mainly bone apposition. But experimental group showed bone resorption at anterior surface of articular eminence and increased bone apposition at posterior surface of postglenoid spine. 6. No marked traumatic change was seen but 4 weeks and 8 weeks experimental animal showed flattening of posterior surperior condylar surface. Bone marrow of condyle showed minute focal bleeding in 2 weeks and 4 weeks experimental animal, and congestion and depression of hematopoietic bone marrow during all experimental period.

  • The purpose of this study is to determine the effect of aromatherapy, showing how the composition handling of aromatherapy and abdominal massage treatment reaches body ingredient transformation. The subjects for this research were total 18 middle-aged females in Seoul; aroma massage group of 7 females, aroma inhalation and water bathe group of 5 females, abdominal massage group of 6 females by jojoba oil without any medical effect. This clinic trial was held from July 1, 2008 to Aug.14, 2008. I held this clinic trial under the same condition after and before this clinic. A standard tape and OLYMPIA 3.5 of S hospital were used at the body measuring for subjects after and before clinic trials. I got Average and standard deviation by data analysis by SPSS Win. Ver.14.0. I did paired t-test for the comparison of before and after, and repeated measure ANOVA for between two groups or among three groups'. The verification was held Duncan Test. The results of this study were as follows: 1. Body mass quotient (F=2.86, p= .063) and Body region (F=1.34, p= .279) among three groups showed no meaningful difference, but weight meaningful difference and aroma massage group showed the greatest difference of body measure change quantity. 2. In change quantity of abdomen girth, Waist circumference and WHR, abdomen girth (F=4.56, p= .012) and Waist circumference (F=4.37, p= .031) showed a meaningful statistical difference. The result of subsequent inspection showed that there was a meaningful difference among three groups and aroma massage group was best. 3. In Cell quantity, Body region quantity and Muscle volume, Body region quantity (F=2.76, p= .182) and Muscle volume (F=3.12, p= .054) showed no difference, but Cell quantity (F=3.79, p= .040) showed a meaningful difference. In the comparison of three groups there was no difference, but aromatherapy group showed more change quantity than any other group. According to the result of this study, the composition handling of aromatherapy and body massage was effective in the decrease of Abdominal fatness and Waist circumference, Weight and the increase of Cell quantity. so I suggest that woman use this therapy in the program of obesity management for her health improvement.
