목적: 본 연구는 요양병원 간호사의 통증관리 지식, 태도, 수행정도를 파악하여 추후 요양병원 통증관리 교육을 설계하는데 기초자료로 활용하고자 실시되었다. 방법: 본 연구는 4개 요양병원에서 근무하는 간호사 120명을 대상으로 한 횡단적 조사연구이다. 통증관리 지식과 통증관리 태도는 원래 연구도구는 Watt-Watson이 개발한 도구를 사용하였고, 통증관리 수행정도는 요양병원에서의 통증관리 가이드라인들을 근거로 연구자가 개발하여 사용하였다. 결과: 본 연구의 결과 통증관리 지식은 40점 만점 평균 26.2점이었다. 가장 많이 틀린 문항은 통증의 주관성에 대한 항목으로 '통증에 따르는 환자의 생리적, 행동적 반응을 보고 통증의 유무와 강도를 파악할 수 있다(89.2%)'였고, 56.7%는 내성의 증가는 마약성 진통제 중독을 의미한다고 생각하였다. 통증관리 태도와 실무에 관해서는, 80.2%가 통증을 자주 호소하는 환자에게 위약을 사용한다고 하였고, 위약사용은 간호사가 두 번째로 자주 사용하는 통증관리 방법이었다. 결론: 본 연구는 요양병원 간호사의 통증관리 지식이 낮고 태도가 부적절한 것으로 나타났고, 이는 통증관리 실무에 부정적 영향을 미칠 수 있다. 요양병원 간호사들에게 통증관리 교육, 특히 통증의 속성과 위약남용에 대한 교육이 시급하다. Purpose: This study investigated long-term care hospital nurses' knowledge and practice of pain management and their attitudes towards the job with an ultimate aim to provide fundamental information for development of a pain education program. Methods: A cross-sectional survey was carried out with 120 nurses from four long-term care hospitals. Nurses' knowledge of and attitudes towards pain management was measured using a tool developed by Watt-Watson. To examine their pain management practice, an instrument was developed based on the pain management guidelines used by the long-term care settings. Results: For pain management knowledge, the participants gave an average of 26.2 (${\pm}13.10$) correct answers out of 40 questions. The most frequently missed question was one about subjectivity of pain, "Patients' physiological and behavioral reactions to pain hint at the presence and intensity of pain" (89.2%), and 56.7% of the nurses believed that increasing tolerance for a narcotic analgesic means addiction. Regarding attitudes towards and practice of pain management, 80.2% of the nurses used placebos to patients who complain about pain often. Conclusion: This study revealed poor level of pain management knowledge of and attitude among long-term care hospital nurses. This might negatively affect their pain management practice. From the educational perspective, nurses should be provided with education on pain management education with emphasis on the nature of pain and misuse of placebo drugs.

In this paper, we studied about several methods of testing hypothesis of correlation, specially Approximate method, Empirical method and Bootstrap method. The Approximate method is based on the Fisher's Z-transformation and the Empirical and Bootstrap methods approximate the distribution of the sample correlation coefficient by Monte Carlo simulation and Bootstrap technique, respectively. In order to compare how good these tests are, we computed powers under various alternatives. Consequently, we see that the Approximate test performs very well even if in small sample and all tests have almost the same power in large sample.

본 연구에서는 고체추진기관의 2차원 축대칭 FSI 해석에서 CSS 및 ISS 기법의 수치 안정성을 고찰하였다. 이를 위하여 CSS 및 ISS 기법을 2차원 축대칭 FSI 수치해석 알고리즘에 구현한 프로그램을 작성하고, 이를 ACM 및 BCM 고체추진기관의 복합거동 해석에 사용하였다. 해석 결과들을 비교 분석하여 ISS 기법이 고체추진기관 FSI 해석의 수치 안정성 개선에 효과적인지 검토하였다. 연구결과, ISS 기법을 적용한 FSI 해석은 시스템 시간간격이 작아질수록 수치적 수렴성을 보이며, CSS 기법과 다르게 시간이 진행되어도 수치해의 진동이 발산하지 않는 것을 확인할 수 있었다. 이를 통하여 ISS 기법을 사용하면 ACM 및 BCM의 FSI 해석에 CSS 기법을 이용할 시 나타나는 수치 불안정성을 개선할 수 있음을 확인하였다. In this paper numerical stability of CSS and ISS schemes in axisymmetric fluid-structure-burning simulation for solid rocket motors are studied. The implemented CSS and ISS algorithms for two-dimensional axisymmetric FSI problems are used to analyze ACM and BCM solid rocket motors. Numerical results from CSS and ISS schemes are compared to investigate the efficacy of ISS scheme over CSS scheme in stabilizing the numerical solution. The ACM and BCM simulation results show that ISS scheme gives stable and converged numerical solutions with appropriately small system time step size, while CSS scheme fails to converge after generating rapidly amplified oscillatory solutions. It is concluded that ISS scheme can be useful in improving the numerical stability of FSI analysis for ACM and BCM solid rocket motor simulations, which is not successfully obtained with CSS scheme.

조현주,원준연,정영규,우봉주,윤준호,황보창권,Cho, Hyun-Ju,Won, Jun-Yeon,Jeong, Young-Gyu,Woo, Bong-Ju,Yoon, Jun-Ho,Hwangbo, Chang-Kwon 한국광학회 2016 한국광학회지 Vol.27 No.4

The thickness of each layer in a multilayered system is determined by a Fourier-transform method using spectroscopic reflectance measurements. To verify this method, we first generate theoretical reflectance spectra for three layers, and these are fast-Fourier-transformed using our own Matlab program. Each peak of the Fourier-transformed delta function denotes the optical thickness of each layer, and these are transformed to physical thicknesses. The relative thickness error of the theoretical model is less than 1.0% while a layer's optical thickness is greater than 730 nm. A PI-(thin $SiO_2$)-PImultilayeredstructure produced by the bar-coating method was analyzed, and the thickness errors compared to SEM measurements. Even though this Fourier-transform method requires knowing the film order and the refractive index of each layer prior to analysis, it is a fast and nondestructive method for the analysis of multilayered structures. 분광광도계로 측정된 반사율 데이터를 활용하여 다층박막 각 층의 두께를 푸리에 변환 방법으로 결정하였다. 이를 위하여 이론적인 3층 다층박막 반사율 데이터를 생성하고 자체 작성한 Matlab 프로그램으로 델타함수의 피크 발생위치로부터 각 층의 두께를 결정하였으며, 박막의 광학적 두께가 730 nm 이상이 되는 경우 결정된 두께 오차는 1.0% 이하임을 알 수 있었다. 이 방법을 사용하여 바 코팅 방법으로 제작된 PI-(얇은 $SiO_2$)-PI 다층박막의 두께를 결정하고 그 결과를 SEM 측정결과와 비교하였다. 본 두께측정 방법은 각 층의 굴절률과 박막의 순서를 미리 인지하고 있어야 하는 단점이 있으나, 비파괴적인 방법으로 빠르게 다층 박막의 두께 분포를 결정할 수 있는 방법임을 확인하였다.

본 연구는 지구단위 차원에서 자연체험 및 휴양 가치를 평가하기 위해 객관적인 평가지표를 도출하고, 이를 토대로 체계적인 평가모형을 설정하는데 가장 큰 목적을 두었다. 우선 문헌분석 결과, 자연체험 및 휴양가치 평가를 위한 평가지표 들로는 층위구조, 포장율, 헤메로비(hemeroby) 등 총 10개의 항목이 도출되었다. 또한, 전문가 설문분석 결과, 평가지표 항목 모두가 4.4 이상으로 높은 중요도 평균값을 나타내었다. 특히 헤메로비 및 독특한 경관요소 항목은 5.8 이상으로 매우 높게 나타났다. 더불어 평가지표들을 특성별로 유형화하기 위해 요인분석을 수행한 결과, '경관구조 및 자연체험 질', '일반적 이용성', '미 시각 질' 등 총 3개의 요인으로 구분되었다. 이상과 같은 설문분석 결과를 토대로 각 요인별 가중치를 산정한 결과, '미 시각 질' 요인이 3.510으로 가장 높은 값을 보였으며, 이에 반해 '경관구조 및 자연체험 질' 요인은 3.035으로 가장 낮은 값을 나타내었다. 이들 결과를 종합적으로 분석하여 체계적인 가치평가 모형을 설정하였다. 또한, 도출된 평가모형의 타당성을 검증해 보기 위해 실 사례지를 선정하여 적용하였다. 우선 사례지의 비오톱 유형분류 결과, 비오톱 유형군은 유수지 비오톱 등 총 13개로 분류되었으며, 이에 귀속되는 비오톱 유형은 총 61개로 구분되었다. 마지막으로 기 설정된 평가모형을 적용한 비오톱 가치평가 결과, I 등급으로는 식생이 풍부한 자연형 하천, 산림과 접해 있는 소규모 수림 등 총 16개 유형으로 나타났다. 반면 II 등급은 9개 유형, III 등급은 8개 유형, IV 등급은 8개 유형, 가치가 매우 낮은 V 등급은 19개 유형으로 분석되었다. The main focus of this research is the establishment of a systemic evaluation model based on objective evaluation indices, which are drawn to assess the experiencing of nature and recreational value at the level of the district unit. First of all, as a result of a literature review, a total of 10 indices can be drawn including vegetation structure, pavement rate, and hemeroby to evaluate an assessment of natural experiences and recreational value. Also, as a result of expert survey analysis, all evaluation index items were above 4.4, which is a high importance average. Hemeroby and unique landscape factor items in particular were above 5.8, which is very high. In addition, as a result of implementing a factor analysis to classify evaluation indices according to characteristics, three factors arise: 'landscape structure and quality of natural experience', 'typical availability', and 'quality of aesthetic and visual sense.' Based on the above survey analysis results, the 'quality of aesthetic and visual sense' was the highest, at 3.510. The classification 'landscape structure and quality of natural experience' was the lowest, at 3.035. A systemic value evaluation model was established by comprehensively analyzing these results. To verify the validity of the evaluation model drawn, real sites are selected and applied. First of all, as a result of a biotope types classification of sites, biotope type groups are classified into a total of 13 including the stream biotope while its subordinate biotope types are classified into a total of 61 groups. Lastly, as a result of biotope value evaluation, which was a previously established evaluation model, there are a total of 16 types including vegetation-abundant natural rivers and small-scale woodlands near forests in grade I. There are 9 types in grade II, 8 in grade III, 8 in grade IV, 19 in the least-valuable grade V.

The purpose of study is to suggest the data on what residential choice elements have to be considered to be important when the apartments are planed in middle size cities. This study analyzed the environmental characteristics of Cheong-Ju city and compared the priority of residential choice elements by using AHP(Analytic Hierarchy Process). The results of analysis are as follows. 1) The rate of housing supply in Cheong-Ju city is low at $80.2\%$ and concentrated on small sized apartments. Furthermore, the educational and traffic facilities are very insufficient. 2) While residential choice in Cheong-Ju is heavily characterized by educational surroundings, it is less affected by economic aspects such as housing prices and the value of investments and accessibility to public transportations, distance to working places. 3) It is affected by residents' general characteristics like as sex, age, life cycle, education level, properties, home ownership, number of room and type of house they want. In conclusion, the middle size cities like Cheong-Ju need the large scale residential plans connected with educational considerations, focused on improvement in quality and outdoor space. In addition, it is recommended to make plans to satisfy the diverse needs of consumers.

In order to investigate the effects of Soyosangamibang Extract(逍遙散加味方抽出液) on antitumor effects after human cell lines(A549, hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI1640 and GIBCO etc., the extracts of its herbal medicines were orally administered for 10 or 12 days. Experimental studies were performed for measurance of antitumor effect of MMC(Mitomycin C) and lysosomal enzyme's activities using colony forming efficency, SRB assay which were regarded as a valuable method for antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows: 1. The change of colony-forming efficiency and SRB assay of Caki-1 cells, hep3B and A549 cells after exposure to the extract of Soyosangamibang extract depressed the growth of tumor cells by concentration of Soyosangamibang, 2. Antitumor activity of the ethanol extract from Soyosangamibang extract and MMC on ascites form of Ehrlich carcinoma in mice is a little improved. Especially mean survival times of the group of 200mg/kg and MMC 0.1mg/kg is improved Over 50%. 3. WhenSoyosangamibang extract and MMC are administrated together, the weight of turnor is more decreased than MMC alone. 4. The lysosomal enzyme's activities of the Soyosangarmibang extract and MMC are more significantly improved than MMC alone. According to the above results, it could be suggested that Soyosangamibang extract has indirect antitumor effect by strengthen the effect of MMC.

조현주,나정화,이현택,구지나,Cho, Hyun-Ju,Ra, Jung-Hwa,Lee, Hyun-Taek,Ku, Ji-Na 한국조경학회 2009 韓國造景學會誌 Vol.37 No.2

본 연구는 비교적 광역규모인 낙동강 약 35km를 대상으로 어느 공간이 환경친화적 친수 휴양공간으로서 개발잠재력이 큰지에 대한 적지선정의 타당성을 검토해 보고, 또한 향후 이 지역의 광역권 휴양계획 수립을 위한 기초자료 제공 및 타 지역으로의 적용가능성이란 측면에서 새로운 방법론을 모색해 보는데 그 의의를 찾을 수 있었다. 연구결과를 요약해 보면 아래와 같다. Mesh법에 의한 사례지의 격자구분 결과, 총 42개의 격자단위로 분류되었다. 또한, 평가지표의 분석결과, 총 20개로 설정되었으며, 이들은 중요도에 따라 다시 4가지의 휴양활동 유형별로 귀속되었다. 각 휴양활동 종류별 평가지표들의 중요성 정도를 분석해 본 결과, 필수요소는 물 이용을 중심으로 한 친수 위락활동공간에서 8개로 가장 많은 지표를 포함하고 있었으며, 충분요소는 정적 친수 휴양활동 공간에서 12개로 가장 많았다. 구분된 각 격자별 최소 요구조건 평가인 1차 평가를 수행한 결과, 최소요구조건을 충족시키고 있는 격자는 전체 42개 중 32개의 격자로 나타났다. 휴양활동 종류별로 최소요구조건을 충족시키는 격자는 연구대상지의 전 구간에 걸쳐 비교적 고른 분포를 나타내고 있음을 확인할 수 있었다. 구체적인 부지 평가인 2차 평가 결과, 우선 자연체험 및 경관생태학습 공간에서는 총 6개의 격자, 운동 및 레크리에이션 중심의 수변 위락활동 공간은 총 4개, 물 이용을 중심으로 한 친수 위락활동 공간으로서는 1개 격자, 마지막으로 정적 친수 휴양활동 공간에 대한 각 격자별 적합성 평가 결과에서는 총 4개의 격자가 매우 적합한 것으로 분석되었다. 그러나 본 연구에서 수행된 격자단위 평가 결과는 지형적 조건 등으로 인해 인접 격자로 확대 및 축소될 수 있다. 따라서 경계의 재조정을 통한 격자형태 및 크기의 변형을 고려한 기본계획을 수립하는 것이 보다 더 타당할 것으로 사료된다. The purpose of this study was to look into the feasibility of site suitability focused on the potential for environmentally- and water-friendly recreation area development in a wide area(Nakdong River 35km) and to study new methods for providing basic data in regard to the recreation planning over a wide area as well as in application to other sites. The results of this study are as follows. Through classification by mesh method, the site of this study was classified into 42 grids, and by means of the analysis of evaluation indicators, 20 indicators were established and sorted into 4 types of significant recreation activity. According to the results of the analysis for each recreation activity type, there were 8 essentials for water-friendly recreation activity types based on water use while water-friendly recreation types for static activity included 12 sub-essentials. As a result of the first evaluation(the minimum required evaluation) by each classified grid, 32 of the 42 total grids were implemented by the minimum requirements. These grids were usually distributed evenly through the whole site. In terms of the second evaluation(specific site evaluation) results, 6 grids were highly suitable for recreational nature experiences and landscape ecological learning, 4 grids for developing water-friendly recreation for exercise, 1 grid for building water-friendly recreation based on water use, and 4 grids for planning water-friendly recreation for static activity. The results of the grid evaluation of this study could be extended to contiguous grids or reduced. Actual planning for a water-friendly recreation area must change the grid shape or size through boundary adjustments.

In order to establish the extent of Streptococcal arthritis piglets, isolation of Streptococci from arthritic lesions of 34 piglets were undertaken from November 1987 to October 1988 in Korea. Also determined were isolation frequency of Streptococci in nasal cavity of 250 healthy sows and antibiotic susceptibilities of the isolates. Streptococci were isolated from 52.9% of 34 arthritic piglets and 20 strains isolated belonged to 4 S suis type I, 8 S suis type II, 2 Lancefield group C and 6 group E. From 28.8% of 250 healthy sows, 72 strains of Streptococci were isolated and these consisted of 9 S suis type I, 51 S suis type II and 12 group C. Streptococcal arthritis seemed to occur prominently in piglets aged 2 to 4 weeks and in male than female. No significant difference were recognized in tarsal and carpal joints as affecting site. All of 92 isolates were sensitive to ampicillin and penicillin, and all strains of S suis type I and group E Streptococcus were also sensitive to chloramphenicol and cephalothin. To cephalothin all strains of group C Streptococcus were sensitive. The 1. 7 to 100% of 92 isolates were resistant with different prevalence to colistin, erythromycin, kanamycin, tetracycline, gentamicin, chloramphenicol and cephalothin. The 92.5% of these resistant Streptococci were multiply drug-resistant strains. The drug resistant patterns most frequently encountered were Tc Cl Em Km Gm(16.3%) in quintuple pattern, Tc Cl Em Km(16.3%) in quadruple pattern, Tc Cl Em(10.9%) in triple pattern and Cl Em(14.1%) in double pattern.
