This study attempts to propose ways to optimize and improve the period of hospitalization for the radioiodine treatment by calculating the dose rate of patients treated with high-dose radioiodine by distance and time slot. As a result, 24 hours after the patient was treated with 100 mCi high-dose iodine, the dose rate was attenuated to $1,035{\mu}Sv/hr$ at the navel, to $109{\mu}Sv/hr$ at 50 cm, and to $33{\mu}Sv/hr$ at 100 cm. 24 hours after the patient was treated with 150 mCi high-dose iodine, the dose rate was attenuated to $637{\mu}Sv/hr$ at the navel, to $100{\mu}Sv/hr$ at 50 cm, and to $40{\mu}Sv/hr$ at 100 cm. 24 hours after the patient was treated with 180 mCi high-dose iodine, the dose rate was attenuated to $1,251{\mu}Sv/hr$ at the navel, $140{\mu}Sv/hr$ at 50 cm, and to $56{\mu}Sv/hr$ at 100 cm. In light of the current criterion for discharge recommended by the US Nuclear Regulatory Commission being $70.4{\mu}Sv/hr$, the present study indicates earlier discharge is feasible by applying a new scheme. This suggests that the proposed scheme in this study will help to solve the problem of shortage of treatment beds with the increasing trend of patients with thyroid cancer taken into consideration.

This study explored the method of determining the appropriate size of the workforce according to the assessment of the workload of medical technologists (also called medical and clinical laboratory technologists, and medical and clinical laboratory scientists) in order to present a standard production model for the appropriate manpower in blood collection rooms. The eleven university hospitals selected for this study had between 600 and 2,000 beds. The 14-steps standard blood collection time was 4 minutes and 8 seconds for the outpatients aged between 20 to 60 years old (57%) except for children and the elderly (43%). Assuming that there were 8 hours per day for mechanically collecting blood, the maximum number of blood donations by one clinical laboratory scientist was analyzed to be 100 cases. In conclusion, it is appropriate to have fewer than 100 cases of daily blood collection by a medical technologist engaged in blood collection. Since the proper number of blood collection workers (100% of blood collection work)=the number of annual working days/(one day's work hours/time per case)×the number of working days per year, then the proper number of blood collection workers (one day's work hours)=the number of working days per year/100×the number of working days).

Mobile X-ray generators are used not in the radiation area but in open space, which causes the exposure of secondary radiation to the healthcare professionals, patients, guardians, etc., regardless of their intentions. This study aimed to investigate the shielding effect of the developed radiation restrictor to block the secondary radiation scattered during the use of mobile X-ray generator. Upon setting the condition of mobile X-ray generator with chest AP, spatial doses were measured by the existence of human equivalent phantom and radiation restrictor, and measured by the existences of phantom and radiation restrictor at the same length of 100 cm. Measurements were taken at intervals of 10 cm every $30^{\circ}$ from $-90^{\circ}$ (head direction) to $+90^{\circ}$ (body direction). Upon the study results, spatial doses in all direction were increased by 45% on average when using phantom in the same condition, however, they were decreased by 64% on average when using the developed radiation restrictor. The dose at 100 cm from the center of X-ray was $3.0{\pm}0.08{\mu}Gy$ without phantom and was increased by 40% with $4.2{\pm}0.08{\mu}Gy$ after phantom usage. The dose when using phantom and the developed radiation restrictor was $1.4{\pm}0.08{\mu}Gy$, which was decreased by 66% compared to the case without using them. Therefore, it is considered the scattered radiation can be shielded at 100-150 cm, the regulation of the distance between beds, effectively with the developed radiation restrictor when using mobile X-ray generators, which can lower the radiation exposure to the people nearby including healthcare professionals and patients.

This study was carried out to collect basic information on the knowledge and attributes and behavior related to the prevention of breast cancer of a Sample Seoul women. Similar studies had dealt with samples of tumor clinic patients and their families and with non-professional hospital welters. The sample for this study was drawn by women out patients from eight centrally located general hospitals, in Seoul where the number of annual out patients exceeded 100,000, and the number of beds exceeded 100. The interview schedule consisted 33 questions related to knowledge, attitude, and behavior related to prevention of breast cancer. It was modified from the previous on cancer studies. The investigator interviewed 665 women over 20 years of age, from those who visited these eight hospitals from 24, June to 20, August 1975. More than half of the respondents were housewives and primarily in the 20 to 29 ages group. They had a mean level of 3.562 pregnancies and 1,986 children. 33.4% were high-school graduates, 32.2% had a monthly family income in the 50,000 to 100,000 won range. 75% of the respondents had heard about breast cancer through mass media or personal media, but the majority of respondents did not have an accurate understanding of it. This varied according to educational, economical income and occupations. The primary reason given for maintaining distance from a patient with breast cancer was not because of cancer but simply because person was a patient. 74.7% of the respondents thought that early cancer of the breast could be cured with early treatment. Only 5.3% of the respondents had ever had a physical examination and only 6.3% practised self examination of the breast.

Antibacterial activities of 33 antibiotics against Pseudomonas tolaasii causing the brown blotch disease on the edible mushroom Pleurotus ostreatus, were tested in vitro for the control of the disease. Tetracyclin, kanamycin, kasugamycin, and streptomycin showed strong antibacterial activity against P. tolaasii, having the minimal inhibitory concentration of 10, 10, 100 and 200ppm, respectively. These antibiotics showed similar control value of 72.9, 71.2, 68.1 and 62.7%, respectively when applied on the artificially infected mushroom beds. Mushroom yields in the tetracycline treated boxes were increased about 31.8% comparing to the control ones. Mycelial growth of P. ostreatus on the PDA supplemented with streptomycin and kanamycin were not affected, but were inhibited 10~20% and 40% with tetracyclin and kasugamycin treatment, respectively.

Sangdong scheelite deposit is confirmed to have been formed by replacement of limestone beds by metasomatic mineralization. Mineralogical zonal distribution and filling temperatures are related with order of its formation and tungsten mineralization. The first formed garnet-pyroxene zone, left in the margins of the ore body, shows the highest filling temperature of fluid inclusions in pyroxene, averaging $420^{\circ}C$. The central part of the ore body, mainly composed of quartz-mica-scheelite, shows higher fi11ing temperatures of fluid inclusions in quartz, than hornblende-quartz-scheelite zone surrounding the quartz-mica-scheelite zone, averaging $240^{\circ}C$. The distribution of highter filling temperatures above average temperature is applicable to the richest part of scheelite distribution. Generally scheelite shows higher filling temperature by about 20 to $100^{\circ}C$ than quartz in a given sample. The crystallization temperature of the main phase of scheelite deposition is $311^{\circ}C$ at the pressure of 230 to 500 bars at Sangdong area. Gas-rich inclusions in the pyroxene are homogenized into either gas or liquid phase or into both phases in a given crystal of the pyroxene, which suggests boiling at the formation of skarn.

Purpose: The purpose of this study was to identify the relationship between gender role conflict for men in nursing, job satisfaction, and turnover intention. Methods: The study data were collected between August 1 and September 1, 2015 from 225 men in nursing currently working in 36 Korean general hospitals, each with ${\geq}100$ beds. Frequency and percentages were analyzed, and Pearson correlation coefficient, t-test, ANOVA, and Duncan's test were used. Results: There was no significant difference in gender role conflict based on the general characteristics of the men. In contrast, significant differences in gender role conflict were found in association with the following job-related characteristics: work experience at the present hospital, work department, work unit, and type of work. A significant negative correlation was detected between male gender role conflict and job satisfaction, a positive correlation was found between male gender role conflict and turnover intention. Conclusion: In order to increase job satisfaction and decrease the turnover intention of men in nursing, measures to reduce gender role conflict are needed.
