Purpose: Since the large hospitals are one of the most intensive energy users among building types in Korea, it is important to investigate and apply appropriate energy conservation measures. There are many researches on energy conservation measures for HVAC system in hospitals, but only few useful guidelines for envelope design variables were existed. The building envelope is one of the important factors to building energy consumption and patients' comfort. The purpose of this study is to suggest the most influential envelope design variables for each end-use energy demand. Methods: 100 samples were generated by LHS(Latin Hypercube Sampling) method. After energy performance simulation, global sensitivity analysis was performed by the regression method. DesignBuilder, Simlab 2.2 and JEPlus were used in this process. Results: The most influencing variables are SHGC, SHGC and VT for heating, cooling, and lighting, respectively. However, the most influencing variable for total energy demand is WWR(Window to Wall Ratio). The analysis was conducted based on the coefficient of variance results. Implications: The six envelop design variables were ranked according to the end-use energy demand.

This study was designed to figure out patient safety culture of medical institutions and try to utilize the study results as basic data for analyzing doctor's awareness of patient safety culture. To this end, questionnaire survey was conducted from August 1st to September 5th, 2011, targeting doctors working at senior general hospitals located in G city, and 194 questionnaires were utilized for final analysis. The research results are as follows. First, there was a difference in awareness of deployment of staffs depending on gender, age, term of service in the hospital, contact with patients and working hours per week in relationship between subjects, wards and hospital safety culture, and organizational learning and teamwork in the ward turned out to be significant in accordance with working hours per week, and all sub-areas of the ward safety culture by departments. Second, feedback about the malpractice, communication, report on malpractice frequency and overall safety awareness were found to be significant by departments in relationship of subjects, medical incident reporting system, patient safety evaluation and overall level of consciousness, and the overall safety awareness showed significant results according to contact with patients and working hours per week. Third, there was a positive corelation in sub-areas of the ward and hospital safety culture awareness, overall recognition and patient safety evaluation, and a positive corelation with medical incident reporting system was found in all areas except for attitude of managers/immediate supervisors and that of hospital executives. Fourth, sub-areas of patient safety culture which has a effect on patient safety showed significant results in organizational learning, openness of communication, overall safety awareness, systematic cooperation between departments, feedback/communication and non-punitive response. In conclusion, to increase the level of the ward and hospital patient safety culture of doctors and implement medical incident reporting system faithfully, it is necessary to activate teamwork through organizational learning in the ward based on the adequate staffing and working hours, promote open communication between departments and provide feedback on medical malpractice, thereby establishing a cooperative system by departments and active support of hospital executives for patient safet.

The Daehan Uiwon (Historic Site No. 248) in which the predecessor of Seoul National University Hospital is a crucial medical institution that built in the Korean Empire period. One of them, East 1 Affiliated Ward that attached to Daehan Uiwon was built with concrete foundation in 1908 and extended two times in 1935 and 1954. As a result of material scientific analysis for concrete foundation, all of the foundation is composed of mortar and stone aggregates, however, the mixing proportions between the aggregate and the mortar were confirmed to be different with construction periods. To determine the mixing proportion, and physical properties by ultrasonic velocity and rebound hardness, the concrete foundations by construction period were obtained. In result, 1954's mixing proportion of concrete between mortar and stone aggregate indicated the highest ratio of aggregates with 1 : 35, mean value of ultrasonic velocity and unconfined compressive strength were calculated with 450 m/s and 18.92 MPa in 1954's constructions that is the lowest values compared with other times. As a result, the difference characteristics of physical properties by construction periods are possible interpreted with porosities and mixing ratios of stone aggregates.

Most large-sized and tall-risen general hospitals of today fairly depend on in-patient wards in designing hospital styles. The core planning for the efficient movements of various people in the words should take into account the sustainable connections between/among the floors, as well as hospital structures and mechanical functions. This study sampled for the study 19 hospital in-patient wards and investigated their flat-core styles. It was found out that hospital structures are changing from symmetrical styles of triangles, quadrangles and rectangles through bending, configuring, transforming to efficient new styles. Symmetrically quadrangled flat-styles are made of multi-cores spread with main an sub-cores. In contrast, symmetrically triangled flat-styles place the open place in the middle in order to prevent from its deepening, and widened the depth line through changing the outdoor top point. Non-symmetrical rectangles minimized the depth value to maintain the recent styles used in the wards, and tended to prefer the transformed styles of quadrangles. The double-corridors easily transshaped from mono corridors reveals the triangled, W-shaped, or Y-shaped figures. The site area ratio of the cores is 11.95% in average. The number of beds which one elevator covers is 66.51 beds in average, and the size of site area which one elevator covers 216.68m. Most cores on the base floor clustered around the average value, with more than 1000 beds shoes 12.83%, does 12.93%, does 14.64%, does 14.58%, which says that the core ratio increases according to hospital beds.

Purpose: The purpose of this study was to identify factors influencing nurses' performance of care in COVID-19 wards. Methods: The participants were 132 nurses who worked in COVID-19 wards at three hospitals, and were recruited from April 1 to May 31, 2021. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with SPSS/WIN 24.0 program. Results: Nursing performance was significantly and positively correlated with ethical sensitivity (r = .75, p < .001), nursing professionalism (r = .67, p < .001), and social support (r = .67, p < .001). Nursing professionalism was positively correlated with ethical sensitivity (r = .64, p < .001) and social support (r = .55, p < .001). Multiple regression analysis for nursing performance revealed that the most significant factor was ethical sensitivity (β = .47, p < .001). Ethical sensitivity, nursing professionalism, and social support explained 66.0% of total variance in nursing performance. Conclusion: Ethical sensitiviy, nursing professionalism, and social support significantly influence nurses' performace of care in COVID-19 wards. It suggests that intervention programs should be directed at improving nurses' ethical sensitivity, bolstering social support, and enhancing nursing professionalism.

Background and objective: The Seoul National University Bundang Hospital (SNUBH) implemented ward-based clinical pharmacy system with designated pharmacists in 10 general wards. Designated pharmacists conduct inpatient medication review, medication intervention, and medication consultation, and provide drug information for health care providers. This study aimed to evaluate the clinical pharmacy services and to examine the perception and expectations of health care providers on the services provided by the designated pharmacists in general wards. Methods: A survey was constructed to include questions on the health care providers' recognition, satisfaction, and perceived needs of designated pharmacists. We determined the frequency and type of interventions of ward pharmacist and their acceptance rate through a retrospective observational study using electronic medical records. Results: A total of 59 health care providers responded the questionnaire and 79.7% of the respondents reported moderate to high levels of satisfaction. Satisfaction with the services was positively associated with clinical interventions and nutrition support team (81.4%). Of 59 respondents, 88.1% agreed that preventing drug-related problems by designated pharmacists' activities were effective. The most common interventions included inadequate dosage (27.4%), omission and additional prescription (14.6%) and inadequate drug form (9.6%). The acceptance rate of intervention was 91.5%, and 151 potentially serious risks and 523 significant risks were prevented by the intervention. Conclusion: Positive results were confirmed in the awareness, satisfaction, and perceived needs of the health care providers for designated pharmacists. Expansion of the ward-based clinical pharmacy system with designated pharmacists to other wards may be considered.

By considering manufacture and economic factor, the steel pipes have been employed for water supply pipeline with large diameter. The standard to decide a thickness of pipe was provided by the waterworks standard (Ministry of Construction & Transportation, 1992) in South Korea. However, there was no the systematic standard to confirm a thickness of pipe in it. Thus, it should be able to apply to unsuitable the Stewart formula for the buried pipe to design for an optimum thickness of pipe. In order to meet revised the waterworks standard (The Ministry of Environment, 1997), it has been considered both the ground condition and all of the stresses to compute a thickness of pipe. As a results, a method is suggested to determine thickness of pipe after comparing and validating the obtained results with the established results from the Stewart formula.
