우리나라의 중환자실 면회 시스템은 대부분 대학병원 기준 하루 2번 20분~30분의 짧은 면회시간을 가지고 있다. 중환자실의 보호자들은 매번 시간을 맞추어 면회를 해야 하며 면회 인원수에도 제약을 받고 있어 제한적인 면회 시스템을 가지고 있다. 이처럼 중환자실의 면회 시스템이 많은 제한을 가지고 있는 것은 중환자실 환자들과 병문객간의 감염 위험 요인을 최소화하기 위함이 있다. 따라서 '중환자실 면회 시스템'을 제작하여 매번 면회를 오지 못하는 상황에서도 원거리 면회를 가능하게 하며 환자와 병문객 간의 감염 위험 요인을 최소화 하여 보호자들에게 심리적인 안정감을 제공하는 것이 목적이다.

Purpose: The purpose of this study was to identify the effects of family visits upon the stress response of patients and their families, Methods: This study was the interrupted time series design, The subjects consisted of 197 patients and 197 family members in the cardiac intensive care unit of S Hospital in Bucheon. Physiological stress responses such as blood pressure, heart rates, respiration rates, and oxygen saturation were measured using HP monitors. VAS was used to measure the emotional stress. Collected data was analyzed using repeated measure ANOVA, t-test by SPSS 17.0 statistical program. Results: The family visits did not change patients' blood pressure, pulse rate, respiration rate and oxygen saturation, However the anxiety level of patients and their family members were decreased significantly during family visits. Furthermore, 30-minute family visit reduced more effectively patient's anxiety than 15-minute family visit. Conclusion: Family visits need to be used as a means of nursing intervention to ease the emotional stress of patients and their families. In addition, increasing of visiting time should be considered.

Purpose: This study aimed to understand the essence of experiences of patients and family members during flexible visiting in an intensive care unit (ICU). Methods: This is a qualitative study using interviews with open ended questions. We used Colaizzi's method of phenomenological interpretation. Results: Flexible visiting in the ICU impacted the patients and their families in various ways. The following categories were extracted from the patients' experiences with flexible visiting: 1) the opportunity to feel the presence of the family and 2) the burden of unrestricted visiting. The following categories were extracted from the families' experiences with flexible visiting: 1) psychological comfort by convenience 2) being aware of health care professionals and critical care nursing in the intensive care unit, and 3) double trouble. Conclusions: These results showed that flexible visiting in the ICU affected the patients and their families positively and negatively. Therefore, nursing staff need to design psychological and social interventions that address the needs of patients and their families.

Purpose: This study aimed to develop an untact visit service based on an application that can be utilized in the pediatric intensive care unit (PICU) during COVID-19. Methods: This study adopted the double diamond process of service design comprising the discovery, defining, and development stages. Results: We developed an untact visit service based on an application that considered the child's status, schedule, photo, and video messages, and so on. Moreover, we derived a service flow regarding the required roles and the type of flow shown between each stakeholder. Conclusion: Considering the ongoing pandemic, the untact visit service is designed to increase rapport and participation of parents, share the child's information in real-time, and provide one-stop service without increasing healthcare providers' work. It will be a useful visit service that can be applied and evaluated in various hospital settings and the PICU.

Purpose: The purpose of this study was to examine the correlation between a flexible parental visiting environment and parental stress in neonatal intensive care units (NICUs). Methods: The study participants included 60 parents of premature infants in NICUs. Structured questionnaires and interviews, as well as observations by researchers using a caregiving behavior checklist, were used to measure the flexibility of the parental visiting environment and parents' stress levels. Quantitative and qualitative data were collected concurrently and were initially analyzed as separate data sets. Data collection extended from March 11, 2018 to June 30. 2018 and the data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, and Pearson correlation coefficients. Results: There was a negative correlation (r=-.30, p=.021) between parental stress and the total number of visits in 7 days. We also found that the average duration of each visit and the number of caregiving behaviors performed by parents were positively correlated (r=.73, p<.001). Conclusion: When designing a flexible visiting environment for parents, parents should be encouraged to visit their babies. By doing so, stress can be reduced both for babies and for parents. Therefore, it is suggested that the related polices and regulations in South Korea should be changed to provide more a flexible visiting environment to promote better parent-child attachment and family adjustment.

판문점 '자유의 집' 설계경기 결과가 지난 6월 20일 공식 발표되었다. 조달청이 통일원의 '자유의 집' 개축 결정에 따라 지난 1월 설계를 공모하고 3월 29일까지 총 12개의 작품을 접수받은 결과 주.담건축(오평국)의 안이 당선작으로 선정되었으며, 주.모양건축(곽동희), 한메건축(이충기)안이 우수작으로 선정되었다. 이번 설계경기의 심사는 정명현(홍익대 심사위원장), 이선구(숭실대), 조대성(성균관대), 이호진(건국대)교수와 이준구(남북회담 사무국 실장)씨 등 5명이 맡았다. 당선된 주.담건축의 인은 자유의 집이라는 건물의 특성에 부합하도록 통일을 소망하는 의미로 두 손을 합장한 형태로 하였으며, 지붕은 강토를 수호한다는 취지로 방패연 모양을 형상화하였다. 1층에는 남측출입구와 이산가족 면회실이, 2층에는 남북통로 및 회의실, 3층에는 남북연락사무소와 다목적 예비실, 4층에는 90층 규모의 전망대가 위치할 예정이다. 오는 7월 실시설계안이 확정되면 97년쯤이면 판문점 자유의 집이 통일의 소망을 안고, 단아하고도 힘 있는 모습으로 자리잡을 것이다.

본 연구는 기업규모, 장부가치/시장가치 비율, 순이익/주가 비율, 현금흐름/주가 비율, 레버리지 등 기본적 변수를 사용하여 주식수익률에 유의적인 변수를 확인하고, 또한 Fama and French(1993) 등에 의해서 제시된 다요인모형(multi-factor model)이 한국주식시장에서 적용가능한 지를 살펴보았다. 이를 위하여 본 연구에서는 Fama and MacBeth(1973)의 횡단면회귀모형과 Black, Jensen, and Scholes (1972)의 시계열모형을 사용하였으며, 실증분석결과를 요약하면 다음과 같다. 먼저 횡단면분석결과에 의하면, 장부가치/시장가치 비율(BE/ME), 현금흐름/주가 비율(C/P) 등이 주식수익률의 횡단면적 차이를 설명할 수 있는 유의적인 변수로 나타났다. 그리고 통계적 의미에서는 1월효과가 존재한다고 보기 어려우나, 경제적 의미에서 1월효과가 존재하는 것으로 생각된다. 시계열분석결과에 의하면, 시장요인, 기업규모요인, 장부가치/시장가치요인(또는 현금흐름/주가요인) 등의 3요인에 의해서 국내 주식수익률의 공통적 변동을 잘 설명할 수 있다. 즉 국내 증권시장에서도 Fama and French(1993)의 3요인모형이 성립될 수 있는 것으로 판단된다.

Purpose: This study aimed to examine the effects of extended family visiting hours in the intensive care unit (ICU). Methods: The subjects were 168 ICU patients and their family members. Two 30-minute visits a day were allowed to the control group according to current policy, while four 30-minute visits a day were allowed to the experimental group. Patients' state anxiety was measured at the first day of ICU admission, and on the third day of ICU admission patients' anxiety and family satisfaction were measured. For the infection rate, comparison was made between the experimental and control data-collecting periods. Results: The patients' state anxiety significantly decreased in the experimental group. Family satisfaction of experimental group was significantly higher than that of control group. There was no significant difference in the infection rate. Nurses positively evaluated extension of visiting hours because it could stabilize patients, reduce the number of arrangements for additional visits, and help establish trust relationship with families. Conclusion: Extended family visiting hours in the ICU reduced patients' anxiety and improved family satisfaction but had no effect on the infection rate. Extended family visiting hours in the ICU is expected to improve the quality of critical care.

It is known that the reduced integration, modified shape function, anisoparametric and non-conforming element can reduce the error induced by stiffness locking phenomenon in the finite element analysis. In this study, we propose new anisoparametric curved beam element. The new element based on reduced minimization theory is composed of different shape functions in each displacement field. By the substitution of this modified shape function, the unmatched coefficient that cause stiffness locking in the constraint energy is eliminated. To confirm the availability of this new model, we performed numerical tests for a simple model. As a result of numerical test, the undulate stress patterns are disappeared in static analysis, and displacements and stresses are close to exact solution. Not only in the static analysis but also in the eigen analysis of free vibrated curved beam model, this element shows successful convergent results.
