Purpose: The purpose of this study was to grasp the effects of role conflicts and burnout on turnover intention and provide intervention methods to decrease turnover intention in nurses of Oriental medicine hospitals. Method: The Subjects were 103 workimg Oriental Medicine Nurses. The data were analyzed by SPSS 18.0. Result: As a result, the mean scores of turnover intention, role conflicts, and burnout were 3.31, 3.53, and 3.44, respectively. Role conflicts had no significant difference in general characteristics, while burnout showed a difference in age, marriage, a working department, a night shift, and a salary, turnover intention showed a difference only in a night shift. Turnover intention was positively correlated with role conflicts(r=.310, p<.002) and burnout(r=.326, p<.001). Role conflicts and burnout explained 20.9% of turnover intention. Conclusion: Therefore, it is necessary to specify specialized and systematical nurses of roles to decrease turnover, make efforts to reduce burnout, and provide methods to decrease turnover intention in nurses of Oriental medicine hospitals.

The purpose of this study was to investigate the effect of parenting stress and role conflict on turnover intention in hospital nurses. This study was 142 nurses working in university hospitals and two general hospitals. The analysis of the collected data was analyzed by using SPSS / WIN 23.0. The average score were parenting stress 2.50 out of 4, role conflict 2.48 out of 5, and turnover intention 2.71 out of 5. In order to analyze the factors affecting the turnover intention, multiple regression analysis was conducted using the role conflict, parenting stress, and job satisfaction. Parenting stress (β= .257 p<.001), job satisfaction (β= .242, p<.001) and role conflict(β=.161 p<.001) were resulted. The explanatory power of these factors Was 45.6%. In conclusion, the turnover intention of hospital nurses was found to be an important factor of parenting stress, role conflict, and job satisfaction. In order to lower the parenting stress and role conflicts and reduce the turnover intention of married nurses, it is necessary to reduce the parenting stress and role conflict in the hospital and home. To improving the job satisfaction of the nurses, it is necessary to improve the workplace environment and welfare.

The purpose of this study is to provide basic data for the development of pre-parent education program by grasping parent role recognition, educational needs and readiness of unmarried men and women. The subjects were 196 unmarried male and female students from K-do. Data were collected from November 1st to 20th, 2018, and analyzed using IBM SPSS WIN/21.0 to get frequency, percentage, average, standard deviation, t-test, ANOVA, sheffe-test, paired t-test, and IPA matrix. The average score of recognition of social pre-parent role was $3.41{\pm}0.27$ (out of 5 points), educational needs was $3.48{\pm}0.41$ points (out of 4 points), and educational readiness was $2.65{\pm}0.57$ points (out of 4 points). educational needs being higher than educational readiness. Through IPA matrix analysis, the area to be strengthened was 'family relation or parent role', and 'self understanding' was the area to encourage putting effort into other evaluation attributes. The area where no further effort is needed and needs improvement in the future was 'spouse selection and marriage', and 'pregnancy and childbirth' and 'child rearing' were the areas to intensively improve. Therefore, there is a need for establishing a standardized strategy in the area A, which has high degree of readiness and needs. Also, it is necessary to take strategies and countermeasures to raise the readiness of area C with low degree of readiness and needs, rather than accepting it as an unnecessary area of further effort input.

본 논문에서는 변형된 Newton-Raphson 알고리즘과 LUT(Look Up Table)를 사용하는 역제곱근 연산기를 제안한다. Newton-Raphson 부동소수점 역수 알고리즘은 일정한 횟수의 곱셈을 반복하여 역수 제곱근을 계산하는 방식이다. 변형된 Newton-Raphson 알고리즘은 하드웨어 구현에 적합하도록 변환되었으며, LUT는 오차를 줄이기 위해 개선되었다. 제안된 연산기는 LUT의 크기를 최소화하고, 순환적인 구조가 아닌 2-stage pipeline 구조를 가진다. 또한 IEEE-754 부동소수점 표준을 기초로 하는 24-bit 데이터 형식을 사용해 면적과 속도 향상에 유리하여 휴대용 기기의 멀티미디어 분야의 응용에 적합하다. 본 역제곱근 연산기는 소수점 이하 8-bit의 정확도를 가지며 VHDL을 이용하여 설계되었다. 그 크기는 $0.18{\mu}m$ CMOS 공정에서 약 4,000 gate의 크기를 보였으며 150MHz에서 동작이 가능하다.

지구 물리학이나 의공학 분야등에서 이용되왔던 전기비저항 탐사법은 관심 영역에 전류 입력을 가한 후, 그에 대한 전압 응답을 측정하여 관심 영역 내의 전기비저항 분포를 규명하는 방법으로서 역해석 문제의 범주에 포함된다. 따라서 일반적인 역해석 문제가 지니고 있는 해의 존재성, 유일성, 그리고 측정 데이터에 대한 해의 연속적 의존성이라는 기본적 문제들을 가지게된다. 이러한 역해석 문제의 해결에는 정확한 정해석 풀이법과 효율적인 역해석 방법이 요구되어진다. 본 논문에서는 정해석 방법으로 유한요소법을, 역해석 방법으로는 전체 최적점을 발견할 가능성이 높은 유전 알고리즘을 최적화 방법으로 사용하였다. 기존의 역해석 문제의 해결책으로 제시되어왔던 기울기 방법에 기반한 결정론적 최적화 알고리즘들이 지니고 있는 국소해로의 수렴, 즉 단순한 전기비저항 분포의 불연속성 확인이라는 한정된 정보의 획득을 넘어서 실제 전기비저항 분포와 가장 가까운 분포는 전체 최적점 근처에서 발견될 수 있음을 보이고자 한다. 이러한 전기비저항 분포의 역해석적인 규명을 간단한 2차원 수치해석문제를 풀어보므로서 확인해본다.

The term 'fourth industrial revolution' was mentioned at the World Economic Forum (WEF) in 2016 and has become a term representing a new industrial era based on information and communication technology (ICT). In the environment of the 4th industrial revolution, ESG management activities are becoming a very important factor in business activities. With the emergence of a new paradigm of organizational operation in the post Covid19 era, the demands for ESG (Environment, Social, Governance) investment related to the environment, social responsibility are increasing. This study examines the role that can support ESG management by utilizing the expertise of appraisers. Real estate is one of the fields of high public interest, and since most ESGs have been conducted centered on the role of private companies, the role of the expert group or the role of public corporations and public institutions is relatively insufficient. If a company or general company engaged in the real estate investment business establishes the role of the Korea Appraisers Association to revitalize ESG management using appraisers, such as ESG appraisers, when investing in real estate, it is believed that it will be possible to promote efficient and sound development of the real estate industry. It was judged that a study on a group of experts was also necessary. In addition, even if the impact of Covid-19 is excluded, it is necessary to gradually introduce an appraisal using non-face-to-face or various advanced technologies (the 4th industry). This study differs from previous studies in that it focused on the role of ESG by the Korea Association of Property Appraisers while research on the role of ESG in public institutions or expert groups is being actively conducted in recent years.

국내 대학은 연구 및 교육 기관으로서의 중요성과 함께 창업에 기여해야 할 사회적 책무를 지고 있다. 대학이 축적한 각종 지식 성과와 함께 연구와 개발 인프라를 활용하고 대학생 및 대학원생의 창의적 아이디어의 활용 가치를 높여 경제 활성화를 위한 새로운 성장 엔진을 개발해야 한다. 또한 창업연구와 창업지원 사업에 대한 사회적 요구에 맞추어 대학은 창업기능을 구조 혁신의 도구로 삼을 기회를 가지게 되었다는 점도 주목해야 한다. 본 연구는 한국 대학의 창업지원 기관의 역할 정립을 위한 학술적 지식을 되짚어 보고 창업을 중심으로 한 대학의 적극적인 창업지원단 구축 모델에 대한 논의를 담고 있다. 창업교육과 창업지원에 관한 기존의 연구와 2차 통계자료를 기반으로 창업지원 방향에 관한 시사점을 획득하고 대학 혁신을 위한 창업지원 모델인 WoW! Valley Model을 제안한다. 본 모형은 창업지원단의 역할 정립에 도움을 주고 대학 창업지원의 정책 수립의 기초를 제공할 것으로 본다. 국내외 경제 여건의 악화와 글로벌 경제 침체 속에서 창업의 사회적 중요성은 점차 커지고 있다. 이러한 상황에서 대학의 창업 활성화는 시대적 과제라 할 수 있다. 체계적인 창업 지원 정책을 대학이 주도하고 현실 학문적 성격을 강화하는 방향으로 체질을 개선하는 일이 시급하다. 본 연구는 대학의 창업지원단 활동의 새로운 모델을 제시하고 있다. 이미 국내의 많은 대학들이 창업지원을 위한 센터나 지원단을 운영하고 있으며 독자적인 체계를 갖추고 있다. 그러나 창업지원을 중심으로 대학의 기능을 재편하는 등의 혁신 체계로서의 창업지원단 운영 모델은 수립 및 시행된 경우가 드물다. 본 연구는 창업교육과 창업지원에 관한 기존의 연구 성과를 되짚어 보고 국내 대학의 창업지원을 위한 새로운 시각을 제시한다. 창업 지원단의 수립 및 운영 모형에 관한 논의가 절실한 시점에서 본 연구는 연구자와 대학 운영자 및 정책 입안자에게 의미 있는 시사점을 줄 것으로 기대한다. 한편, 본 연구는 개념적 디자인을 제시하는 수준이므로 디자인을 평가하여 새로운 지식을 얻는 등의 후속 과정을 거쳐 보완될 필요가 있다. 다중 사례 연구와 실행 연구(Action Research) 등의 실증 방법을 통해 본 연구의 후속 결과가 요구된다.

In order to determine the optimal number of monitoring points in single-track tunnel lining, this thesis compares and evaluates the results of two cases: when the tunnel lining is modeled into a simple beam form and then is applied to 1) the tunnel lining inverse analysis program, and to 2) the commercially-used program. The displacement and stress of specific tunnel lining cross-sections are determined by entering the load conditions into the commercially-used program for tunnel interpretations. In doing so, two cases were assumed: where a symmetrically-distributed load was acting upon the tunnel lining of a single-track tunnel and where an asymmetrically-distributed load was in action. By comparing the computed displacement with the stress and displacement determined by entering side numbers 3, 5, and 7 into the tunnel lining inverse analysis program, the optimal number of monitoring points is determined. From the results of the research, it can be inferred that the number of monitoring points needs to be at least 5 points, considering the efficiency of monitoring in practice and the loss-and-damage rate of tunnel monitoring.

The purpose of this study was to identify the loneliness and spiritual needs of the elderly in a certain area. The participants in this study were over 65 years, 159 elderly who attended in senior classes in Seoul. The instruments used for this study were revised UCLA 'Loneliness scale' developed by Russell, Peplau & Cutrona (1980) and translated by Kim & Kim (1989) and 'Spiritual need scale' developed by Yong (2008). The collected data were analyzed using SPSS 15.0 program, t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. The score of loneliness was 2.02/4, spiritual need was 4.51/5. The relationship between loneliness and spiritual needs showed significant negative correlation. Loneliness of the elderly who do not attend a religious attendance was high and spiritual needs were low. Spiritual needs of the elderly who are women over 80 years and living with subsidy from the government were high. Spiritual nursing interventions are needed to reduce a feeling of loneliness among the elderly who experience high degree of loneliness.
