As a descriptive survey, this study was attempted to get basic data necessary to recognize the factors that disturb the therapeutic atmosphere of hospital wards as perceived by nurses and hospitalized patients, to identify differences between the perceptions of the nurses and of patients. The subjects, 159 patients in Pusan National Hospital and 68 nurses working there were sampled between March 18 and April 13, 1996. The tool used to measure the disturbing factors was an amended form of the one developed by Kim, Mae Ja(1983). The differences between each subject's score for each factor were analyzed using means & SD. and the highest 3 items above the mean score for each factor were collected and compared. The results are described below : 1. Subject's perception of main disturbing factors : patients reported that the main factors were 'loss of role & economic trouble', 'the prognosis of disease', 'the change of daily life' but nurses replied that the main factors were' the prognosis of disease', 'the communication trouble with the medical team & interpersonal relationships'. 'The change of daily life' was not a perceved factor by nurses, but ranked third by the patients. 2. Subject's perception degree of each disturbing factor : (1) among the items related to interpersonal relationship. the patient group reported that the worst disturbance was dur to severely ill patients in the same room' but the nurse group regarded 'greed to monopolize wheelchairs or other supplies' as the worst disturbance. (2) among the items related to physical factors. the patient group regarded 'limitations to wash their body, physical pain and limitations in physical activity' as the worst disturbance, but the nurse group regarded' physical pain', and 'limitations to activity or change of appearance' as the worst disturbance. (3) among the items related to the change of daily activity, the patient group regarded 'the boredom of hospitalization or infavorable diet' as the worst disturbance, but the nurse group regarded 'too much noise or unclean room' as the worst disturbance. (4) among the items related to the communication trouble with medical team, the patient group regarded 'the ignorance of their disease due to poor information. the inability to understand the language of the medical team or the difficulty in seeing physician in time' as the worst disturbance, but the nurse group regarded 'the inability to trust physicians and physician's poor attention to patients' as the worst disturbance.

This study aimed to identify the mediating effect of nurse's communication on the relationship between nursing needs and nursing satisfaction in hospital patients. After IRB approval, this study was performed by administering questionnaires to 180 university hospital patients between April and June, 2017. Collected data were analyzed with SPSS 22.0. The average score of nurse's communication, nursing needs, and nursing satisfaction were $3.88{\pm}0.52$, $3.96{\pm}0.55$, and $3.74{\pm}0.59$ out of 5, respectively. There were significant differences in educational and therapeutic needs versus satisfaction. As for nurse's communication and nursing satisfaction, there were significant differences by patient's room. There were positive correlations among nurse's communication and nursing needs (r=.286, p<.001) as well as nurse's communication and nursing satisfaction (r=.524, p<.001), In addition, there were positive correlations between nursing needs and satisfaction (r=.488, p<.001). Nursing communication had a partial mediating effect between nursing needs and satisfaction, which showed significance in Sobel's test (Z=2.450, p=.014). Therefore, it is suggested that a continuous program for strengthening communication of hospital nurses is needed.

This study suggested a method for prediction of residual chlorine and THMs in water distribution system by measurement of residual chlorine, THMs, and other parameters, estimation of chlorine decay coefficients and THM formation coefficients, and simulation of water qualities using pipe network analysis. Bulk decay coefficients of parallel first-order were obtained by bottle tests, and pipe wall decay coefficients of first-order were estimated through evaluation of 5 models, which showed the lowest values of 0.03 for MAE(mean absolute error) and 0.037 MAE in comparison with the observed in field. And bottle tests were conducted to model first-order reaction of THM formation by nonlinear least square regression and the resultant coefficients were compared with the observed in field. As a result, the coefficients of determination$(R^2)$ for the observed and the predicted values were 0.98 in September and 0.82 in November, and the formation of THMs was predicted by modeling.

Purpose: All acts which are enforced from the radioactive iodine therapeutic team is a in its own way principle and provision. Therefore unification of all acts can not be appropriately. We will make the standard coherence. Materials & Methods: From 5 November, 2007 to 17 November 2007, we conducted a questionnaire survey of the nuclear medicine manager of 30 hospitals. The contents of a questionnaire is medical treatment section, patient management, prosecuting attorney section, waste management and safety supervision in about the patient and a questionnaire was drawn up in the method which selects an item. Results: 30 hospital agencies are operating purely for I-131 high dose ablation therapy. Diagnostic study and daily schedule had the difference of some. The most of education for the patients took charge of doctor and nurse. The satisfaction of education was evaluated as the high thing. The safety supervision of waste management accomplishment and Safety supervision the patient and the worker observed on the basis of atomic energy law. Conclusion: Specific standards with sufficient amount of information and practical contents should have been presented through the following data. However, it seems to be lacking in many aspects. Nevertheless, respondents rated 70.9%, which is relatively high, on the value of clinical utilization, and I am very thankful for the evaluation. For many years from now, it may seem necessary for a lot of research on the specific matters based on these data to be conducted.

Purpose: It is important to plan the ward module at a time when the size of beds, the floor area, and the construction budget are all set prior to the hospital design. In this context this study aims (1) to derive various factors affecting the ward module, and (2) to analyze the appropriate room module according to the type. Methods: Design factors related to hospital modules are derived through precedential studies, and the types of ward elevation are classified by reviewing the drawings of 18 case hospitals. And the detailed dimensions and area of the derived elements are analyzed. Results: The X-axis modules of the ward are switched to long span structural columns of 9.9 m, 12.6 m and 13.2 m, but the ward modules still represent 6.6 m. The Y-axis module of the ward shows a dimension of 9 to 9.9m in the process of changing a multi-person room into a four-person room. Type A of curtain wall with columns located on the wall of the room and type B of curtain wall located in the center of the room are analyzed due to their variations. The square window type, which forms the elevation of the square window by exposing the columns to the elevation, and the outframe type, which protrudes from the structural columns and beams, have elevation designs limited. There are, however, no obstacles to the interior space of the hospital room, so the wall composition and furniture arrangement are expected to be free. The ward area of Curtain Wall Type A, which can secure an effective area of 5.9m*5.0m, are 52.1m². The Curtain Wall Type A, Square window type, and the outframe type are 49.8m². Implications: As part of the hospital standard module plan for economical and reasonable hospital building planning, a type was proposed in this study in conjunction with the external design. It is hoped that it be a base for standard module research linked together to the Central Treatment department, Outpatient department and underground parking lot.

This study was carried out to evaluate the effects of disinfection using environmental disinfectant after having assessed the extent of contamination through microbial culture testing and the Adenosine Triphosphate Bioluminescence method among the environmental management evaluation methods used for the environment in the hospital ward of patients infected by multidrug-resistant organisms. This study was conducted with the patient wards isolated due to multidrug-resistant organisms as the environmental surface. Specimens were collected from five locations including infusion pumps, IV poles, bedside cabinets, bed railings, keyboards, and blood pressure measurement cuffs. ATP and microbial culture testing were executed prior to, immediately after, and five minutes post-disinfection. According to the result contamination of the infusion pumps was statistically significantly reduced after disinfection. In addition, the bacteria before and after disinfection reduced in IV pole, bed railing, and keyboard. That is, regular environmental surface disinfection can provide safer environments to patients against infection. Therefore, it is necessary to establish guidelines including disinfection methods and intervals for environmental surfaces by evaluating the persistence of disinfectants at various institutions in the future.

In this study, the radiation dose rate was measured by time and distance and evaluated whether radiation dose rate was suitable for domestic and international discharge criteria. In addition, the radiation dose emitted from the patient was measured with a glass dosimeter to evaluate the exposure dose if the caregiver stays in the isolated ward by placing a humanoid phantom instead of the caregiver at a distance of 1 m from the patient, on the second day of treatment. After 23 hours of isolation, the radiation dose rates at a distance of 1 m were 20.54 ± 6.21 µSv/h at 2.96 GBq administration and 27.94 ± 12.33 µSv/h at 3.70 GBq administration. The radiation dose rates at a distance of 1 m were 25.90 ± 2.21 µSv/h when 2.96 GBq was administered and 34.22 ± 10.06 µSv/h when 3.70 GBq was administered after 18 hours of isolation. However, if the isolation period is short may cause unnecessary radiation exposure to the third person. The reading of the attached dosimeter from the morning of the second day of treatment until removal was 0.01 to 0.95 mSv, which is a surface dose determined by the International Commission on Radiation Units and Measurements. And the depth dose was 0.01 to 0.99 mSv. On the second day of treatment, even if the patient caregivers stayed in the isolation ward, the exposure dose of the patient family did not exceed the effective dose limit of 5 mSv recommended by the ICRP and NCRP.

ln this paper, flowfields inside the various rooms have been investigated. A storage room, a liv-ingroom with a kitchen in an apartment, and a hospital room are considered in the present calculations. In all cases, it was found that the average of air change rate is. similar to that of perfect mixing assumption and the location of air purifier has little effects on the average air change rate. Detailed local air concentrations show that there are regions where air is not quite purified because of non-uniform circulation of air flow. The location of air purifier has great effects on this behavior.

난청은 가장 흔한 선천성 장애이다. 이 질병의 발생 빈도는 신생아 1000명 출생 당 $1{\sim}3$명 정도로 상당히 높다. 이러한 청력 장애가 조기에 발견된다면 수술적인 치료 등으로 예방할 수 있으나 그렇지 못할 경우 언어와 학습장애를 초래하게 된다. 이런 관점을 근거로 신생아를 대상으로 한 선천성 난청의 선별검사는 큰 의미를 가지며 난청환자의 조기발견을 위한 노력이 필수적이라 할 수 있다. 기존의 수동 청력검사 시스템은 신생아 청력 평가시 검사자의 주관성에 의존하게 되므로, 청성뇌간 반응의 뇌파분석이 잘못될 가능성이 커진다. 따라서 본 연구에서는 청력 역치를 자동으로 판독하여 결과를 나오도록 개발하고자 하였으며, 또한 기존 제품들과는 차별화하여 휴대용으로 개발하여 차폐실이 아닌 일반 병실에서도 검사가 가능하도록 함에 따라 유소아의 청각 장애를 극복시키는데 기여하고자 하였다.
