양기와 음기를 보하는 약재로 알려진 양기석과 음기석 및 연옥에 대한 의료적 활용을 파악하고, 광물학적 특성, 분광학적 및 자기적 특성을 규명하기 위하여 X선 형광분석, X-선 회절분석, 주사전자현미경, 적외선 분광분석, 핵자기 공명분석 및 감응자기력을 실시하였다. 광물성 한약으로 사용되는 양기석은 양기석으로 확인되었으뗘, 연옥은 투각섬석으로 구성되었다. 또한, 음기석은 주로 질석으로 구성되며, 소량의 카올리나이트와 할로이사이트를 함유하였다. 사슬형 규산염 중 각섬석군에 속하는 이들 연옥과 양기석은 유사한 범위의 분광학적 특성을 가지며, 연옥은 4$0^{\circ}C$에서 방사에너지가 큰 반면, 양기석은 15$0^{\circ}C$에서 방사에너지가 크다 음기석은 각섬석군의 광물보다 4$0^{\circ}C$와 15$0^{\circ}C$에서 모두 낮은 방사에너지를 나타내었다. 광물성 한약을 증류수에 20일간 침적한 후에 측정한 NMR분석에서의 선폭은 음기석, 양기석, 연옥의 순으로 감소되나, 80일이 경과한 후의 결과는 음기석, 연옥, 양기석 순으로 감소하였다. 양기석과 음기석은 가열 온도가 높아짐에 따라 감응 자기력 값이 대체적으로 증가하고, 연옥은 감소하는 경향을 나타내었다. 광물별로는 상온과 가열시 모두 음기석, 양기석, 연옥의 순으로 감소하였다.

In this paper, we study the root system of rank 2 hyperbolic Kac-Moody algebras. We give some sufficient conditions for the existence of imaginary roots of square length $-2k(k{\in}\mathbb{Z}_{>0}$. We also give several relations between the integral points on the hyperbola $\mathfrak{h}$ to show that the value of the symmetric bilinear form of any two integral points depends only on the number of integral points between them. We also give some generalizations of Binet formula and Catalan's identity.

Let g = g(A) = (equation omitted) + be a symmetrizable Kac-Moody Lie algebra of type D/sub l//sup (1) with W as its Weyl group. We construct a sequence of root spaces with certain conditions. We also find the number of terms of this sequence is less then or equal to the hight of θ, the highest root.

Purpose: The purpose of this study was to explore the experiences of female nurses who are working with the male nurse as a colleague in the clinical settings. Methods: Eleven female nurses who were working with a male nurse over six months were interviewed, and the data were analyzed by using the Giorgi's phenomenological method. Results: Six main meanings and nineteen themes emerged through this study. The six main meanings were as follows; prejudice against male nurses' roles, difficulties in establishing collaboration and trust as a peer, deficit of intimacy due to inappropriate attitude, weakening stereotypes ideas about male nurses, permissive mind of gender difference and individuality, expectations to the male nurses' contributions to nursing profession. Conclusion: These results could be utilized in the development of effective strategies to improve the male nurses' adaptation to the nursing clinical settings.

Purpose: The purpose of this study was to understand the meaning and essence of happiness by exploring and describing career nurses' lived experiences. Methods: Qualitative research was used in this study. Hospital nurses who had 3~5 years of experience in the clinical setting were interviewed and the data were analysed using Giorgi's phenomenological method. Results: Six main meanings and seventeen themes emerged. The six main meanings were as follows: self-confidence as a professional nurse, passion for self-realization, feeling of satisfaction in performance of nursing care, being grateful for working environment, emotional intimacy in interpersonal relationships, and taking delight and pleasure in leisure life. Conclusion: The results of this study provide deep understanding of happiness as positive experiences that increase job satisfaction and aid retention to the nursing profession. These results can be used in the development of effective strategies to improve and expand nurses' happiness.

Purpose: The purpose of this study was to explore the lived experiences of new graduate nurses in personal life and in clinical setting during their first year. Methods: Eleven new graduate nurses were interviewed and the data were analyzed using the Giorgi's phenomenological method. Results: The main results of this research were negative experiences such as poor nursing skills, inability to enjoy personal life, physical exhaustion and health problems, and uncertainty of nursing values. On the other hand, there were some positive aspects on their minds: adjustmental/developmental needs, sense of responsibility, receptive capability, and proficiency with their work. They gradually found themselves being endured and changing to adapt. Conclusion: Transition from students to staff nurses is a very stressful experience for new graduate nurses. It may negatively affect their personal lives as well. However they tried to keep themselves positive to overcome their difficulties. It is necessary for them to be given time, a systematic program, and a supportive environment to adapt.

In this paper, we study the Lie-generalized Fibonacci sequence and the root system of rank 2 symmetric hyperbolic Kac-Moody algebras. We derive several interesting properties of the Lie-Fibonacci sequence and relationship between them. We also give a couple of sufficient conditions for the existence of the integral points on the hyperbola $\mathfrak{h}^a:x^2-axy+y^2=1$ and $\mathfrak{h}_k:x^2-axy+y^2=-k$ ($k{\in}\mathbb{Z}_{>0}$). To list all the integral points on that hyperbola, we find the number of elements of ${\Omega}_k$.

Purpose: This study is a descriptive study to analyze the relationship between the cognitive function, body image and pain, and the influencing factors on the daily life performance of brain injured patients. Methods: The study subjects were 119 inpatients with brain injury who gave informed consent. The activities of daily living (ADLs), cognitive function, pain and body image were measured by Modified Barthel Index (K-MBI), K-MMSE (Mini-Mental State Examination), Visual Analog Scale (VAS), Semantic Differential Method (SDM), respectively. Results: ADLs was significantly associated with body image, cognitive function, and pain. Multiple regression analysis showed that paralysis, consciousness, cognitive function, and pain were significant factors influencing ADLs. Overall, approximately 48% of total variability in the ADLs could be explained by the 4 variables ($R^2=.477$, p<.001). Conclusion: To improve ADLs of brain injury patients, a deeper understanding of paralysis, consciousness, cognitive function, and pain of patients is required and active nursing invention should be conducted.

Purpose: The purpose of this study was to identify the influences of type D personality, burnout and work environment on nurses' intention to stay at the hospitals among nurses. Methods: A cross-sectional descriptive design was used. Participants were 135 nurses working at general hospitals. Data were collected using self-report questionnaires. Data were analyzed using the SPSS/WIN 23.0 program for descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and hierarchical multiple regression. Results: The score of nurses' intention to stay was 4.78. 39.3% of participants were classified as type D personality group. The scores of burnout and work environment were 2.92 and 2.39, respectively. Intention to stay was negatively correlated with burnout and positively correlated with nurse participation in hospital affairs, nursing foundations for quality of care, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy. Burnout and manager ability, leadership, and support for nurses explained 46.0% of variance of nurses' intention to stay in the hospitals. Conclusion: The results of the study indicate that nursing intervention programs for increasing intention to stay for nurses should include strategies for decreasing the burnout and increasing manager ability, leadership, and support for nurses.

본 논문은 확률적 자료연계 방법의 기본 개념과 이론적 모형을 소개하고, 실제 통계청 데이터를 사용하여 확률적 자료연계가 진행되는 과정과 원리를 보여준다. 먼저 확률적 자료연계와 결정적 자료연계와의 차이를 간단히 알아보고, 확률적 자료연계 방법론의 토대가 되는 Fellegi-Sunter 모형의 기본 구성과 관련된 모수(m-확률, u-확률), 가중치, 매치여부 판정기준에 대해 기술한다. 그리고 통계청 등록센서스와 인구총조사 자료를 이용하여 그 모형을 적용한 자료연계가 이루어지는 구체적인 과정에 대해 설명하고, 이를 통해 얻어진 연계 결과의 정확성을 살펴본다.
