Many of hotel customers obtain information from hotel websites to find the best alternative. One of the crucial information for the choice is spatial/visual information of hotel rooms. However, hotel website provides photographs only showing representative room features that may not be sufficient to give a full understanding of hotel room to customers. HMD-based 3D virtual environments (HVE) created by 3D camera could improve customers' experiences of hotel rooms by providing full virtual tours of hotel rooms. However, to the best of our knowledge, whether HVE can adequately provide similar customers' perception on spatial/visual information remains unproven as physical hotel rooms. The present study thus aims to verify how similar and reliable information on physical hotel room HVE provides to hotel customers in comparison with hotel website with 2D photograph and display-based 3D virtual environment. For this purpose, this study conducted a comparative experiment to investigate perception of three environments. As a result, the study found that HVE is more effective to provide spatial/visual information as similar as an actual hotel room. In addition, HVE increases customers' perceptions towards the reliability of information, the quality of hotel room and intention to book.

The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

Purpose: This study aimed to examine the occupational injuries experienced by operating room nurses and investigate the relationship between these injuries and safety climate. Methods: The study involved 198 operating room nurses working in general and tertiary hospitals with more than 300 beds. Results: Among the four sub-factors of occupational injuries experienced by operating room nurses, risks due to ergonomic hazards were the most prevalent and those due to physical hazards were the least. The scores related to occupational injury showed a significantly negative correlation with the safety climate. Conclusions: The findings indicate that higher operating room nurses' awareness of the safety climate is associated with lower rates of occupational injury. Therefore, organizational efforts and interventions are imperative to improve the safety climate within hospitals. Additionally, in order to investigate the safety of operating room nurses more in-depth, it is necessary to expand not only the sample size but also the geographic scope.

This study was to design the clean room garment which fits for a body and adjusts well to the action. We examined the body's changes in action through a body measurment and made a sample of the clean room garment to which had adapted the body's changes in action and evaluated the function and the appearance compared with the existing the clean room garment. The followings were summery of the results : 1. Back intersyce breadth decreased, trunk length increased and the other parts were not change. At a posture of raising hands($M_3$) in comparison with an upright posture($M_0$). Back intersyce breadth, hip length and knee length increased and the other parts were a little change. At a bowing posture($M_2$) in comparison with an upright posture($M_0$). Back hip girth, knee length, hip length and leg length increased and the other parts were not change. At a working posture on a chair($M_1$) in comparison with an upright posture($M_0$). 2. The overall clean room garment was made increasing on the changes of part of a body through measuring and body measurement. 3. From the test of the function, it became known that the devised clean room garment was superior to the existing one in the parts of neck, shoulder, armpit and elbow at a working posture on a chair($M_1$), in the parts of neck, shoulder, and armpit at a bowing posture($M_2$), and the armpit at a posture of raising hands($M_3$). The appearance was better on the whole. 4. From the examination of photographs, the waist line of the devised clean room garment was not so much pulled up as that of the existing one on moving. And when sitting down on a chair, the waist line of the existing one was pulled down while that of the devised one had no change. As above, we investigated the actual conditions of wearing the clean room garment and measured the body's changes according the various actions. So we applied these results to the devised clean room garment but we couldn't research the clean mom effect of it owing to not obtaining the measuring instrument. The aspect of ergonomics liked the feeling of wearing and fitted to the action must be given consideration to the clean room garment, and simultaneously the dust-resistant effect must be taken into consideration in order to improve the quality of the goods. Therefore, we think it should be continued the research on the dust-resistant effect, material, washing method, quality control, and size along with the aspect of ergonomics.

Deproteinization has been recognized as a prerequisite for amino acid analysis of plasma samples. For plasma stored at room temperature, delaying deproteinization for 30, 60 or 120 minutes did not result in significant changes in the mean CV (coefficient of variation), which ranged from 4.4 to 5.6%. However the mean CV of aspartic acid, ${\alpha}$-aminoadipic acid, alanine and lysine was about 10%. When the plasma was stored frozen at -20${^{\circ}C}$, the CV was increased at 0 and 120 minutes after thawing, to 12.4% (range, 4.1 to 35.3%) and 8.0% (2.5 to 30.7%), respectively. The concentrations in plasma during storage at room temperature of all the amino acids analyzed showed significant changes. In plasma stored for 30 minutes at room temperature, 17 amino acids increased in concentrations and two decreased. Extending this period to 60 or 120 minutes increased the instability as compare to the reference group. Storing plasma at -20${^{\circ}C}$ for 2 weeks resulted in significantly greater changes in the amino acid concentrations than at room temperature. On extending the storage time at room temperature, after thawing, to 30, 60, and 120 minutes, 21, 20, and all 22 amino acids respectively changed significantly (p<0.01). The present study indicates that methodological errors occur in the concentrations determined for all amino acids when plasma is left at room temperature. The storage of frozen non-deproteinized plasma accompanied more significant changes in most amino acid concentrations and thus should be avoided. Deproteinization should be performed as soon as possible after plasma collection.

Methods : This study selected 271 workers of 119 briefing room at National Emergency Management Agency and fire stations, metropolitan cities and provinces to examine the influences of job stress of 119 briefing room workers on depression. and as a result of analysis, the following conclusions. Results : 1) The whole average of job stress measure was 3.30. The highest area was interpersonal relationship factor as 3.41, 'job characteristic factor' as 3.36 and communication factor' as 3.01. 2) Total score of whole items of depression was 11.88 and showed slight depression level. 3) There was static correlation between job stress and depression(r=44.7, p= .000). There were statistically significant static correlations between job stress factor and depression(r= .388, p= .000), interpersonal relationship factor and depression(r= .471, p= .000), and communication factor and depression(r= .386, p= .000). 4) There was statistically significant difference in the influence of job stress on depression(B=8.575, p< .001). Influence of job stress on depression was explained as $R^2=.200$. When job stress factors as independent variables were input, interpersonal relationship factor(B=5.062, p< .001) had the greatest influence on depression and there was no statistically significant difference in communication factor(B=2.490, p< .05). Conclusions : It is considered that development of the various programs including program for getting rid of job stress of 119 briefing room workers and counseling program will be needed. particularly, factors such as human relationships and communication in the area of job stress must be the first priority.

Background : This study was attempted to provide a basic information necessary for the development of measures evaluating perceived discomfort of the patients under local anesthesia and the developments of nursing intervention and nursing standard. Method : The study subjects were a convenience sample of 100 surgical patients under local anesthesia. The researcher visited the patients directly and explained the purpose of the study to them. Then they were asked to fill out questionnaires which were developed and structured by the researcher, under their prior permission. Out patient's data were collected at recovery room after operation. Results : Factor analysis on measures evaluating the patients under local anesthesia showed that the measures consisted of eight factors including "explanation", "humane treatment", "motion limitation", "pain", "no togetherness", "waiting", "the environment of operating room", and "unkindness". When analyzing each of the factors regarding their degree of contribution to perceived discomfort, it was found that "waiting" was highest in terms of the degree. According to general chara-cteristics of the sampled patients, the factor of "explanation" contributed to perceived discomfort more in male patients than female ones. Regarding parts of medical examination, the patients of otorhinolaryngology felt perceived discomfort most because of the factor of "pain". Conclusion : To relieve perceived discomfort the patients under local anesthesia require providing individually systematized nursing services which can reduce perceived discomfort according to each of the factors. In doing so, an unlimited attention and much effort should be given to realize CQI reaching the dimension of increase in comfort as well as decrease perceived discomfort.

With 106 detached houses where the aged people live alone, this study was conducted to perform a location survey of their residential environment. The result of this study is summarized as follows: While the surveyed houses' safety, sanitation and convenience appeared to be positive, with respect to the conditions of location, 73％ of the surveyed houses did not meet the requirement for comfort. The average area of each space indicated that the bedding room was 12.05$m^2$, the living room 14.71$m^2$, the kitchen 9.06$m^2$, the bathing room 4.05$m^2$, and the rest room 2.59$m^2$. Then, 93.3％ of the bedding rooms had the doorsill. Also, 97.2％ of the surveyed houses had retrievable space. The form of their living room door showed a hinged door(54.5％) and a sliding door(45.5％) which were similar with each other. The finished material was that wood accounted for 42.6％ which was highest. The cooking table form of kitchen was mainly "\ulcorner"-shaped(49.5％) and "\ulcorner"-shaped(48.5％) which were highest, and their average height appeared to be 815mm. The fuel used for kitchen was that gas accounted for 93.3％, while 95.2％ of the surveyed houses was not equipped with any gas-warning device. 75.5％ had an integrated type of bath room and toilet. In addition, the stepped difference between the bath room and other space was that 70.8％ had the difference, but they had no a satisfactory sliding-prevention device(Not for 91.6％) or heating system(Not for 92.9％).stem(Not for 92.9％).
