Medical radiation offers significant benefits in diagnosing and treating patients, but it also generates unnecessary radiation exposure to those nearby. Accordingly, the objective of the present study was to analyze spatial dose rate according to types of radiation source term in multi-bed hospital rooms occupied by patients and general public. MCNPX was used for geometric simulation of multi-bed hospital rooms and radiation source terms, while the radiation source terms were established as whole body bone scan patients and imaging using a portable X-ray generator. The results of simulation on whole body bone scan patients showed $3.46{\mu}Sv/hr$ to another patient position, while experimental results on imaging using a portable X-ray generator showed $1.47{\times}10^{-8}{\mu}Sv/irradiation$ to another patient position in chest imaging and $2.97{\times}10^{-8}{\mu}Sv/irradiation$ to another patient position in abdomen imaging. Multi-bed hospital room, unnecessary radiation generated in the surrounding patients, while legal regulations and systematic measures are needed for radiation exposure in multi-bed hospital rooms that are currently lacking in Korea.

Dolomedes spiders of the family Pisauridae are one of free wandering spiders with semi-aquatic habitation. They do not build web for prey-hunting but build a nursery web for spiderlings. This paper describes the fine structure of the silkspinning spigots of the fishing spider Dolomedes sulfureus revealed by the field emission scanning electron microscope (FESEM). The fishing spider Dolomedes sulfureus possesses only three types of silk glands which connected through the typical spinning tubes on the spinnerets. The silk spigots of this spider were identified as three groups: ampullates, pyriforms and aciniforms. Two pairs of major ampullate glands send secretory ductules to the anterior spinnerets, and another two pairs (or $1{\sim}2$ pairs in males) of minor ampullate glands supply the middle spinnerets. In addition, the pyriform glands feed silk into the anterior spinnerets ($62{\sim}68$ pairs in females and $45{\sim}50$ pairs in males), and the aciniforms send ductules to the middle ($33{\sim}40$ pairs in females and $18{\sim}25$ pairs in males) and the posterior spinnerets ($42{\sim}50$ pairs in females and $24{\sim}28$ pairs in males). Among these, the ampullate one is the most predominate gland in both sexes.

Our study was carried out to suggest the way of improving the accessibility of medical service through identifying the factors that make patients be hospitalized in non-residential area not in their residential area. The subjects were 523,782 inpatients of the 2005 Patient Survey data. The 2004 Hospital Evaluation data, the 2005 census data which were obtained from the Korean National Statistics Office, and the 2006 Survey on National Healthcare Resources data were used. The data were analyzed using descriptive statistics, chi-square test and logistic regression in a SAS program. The most important factor was quality level of care of local hospitals. In the possibility of being hospitalized in non-residential areas, the region with the score of more than 9.5 per 100,000 people in the hospital evaluation was 8.3 times more than the region with the score of less than 9.5. However patients is hospitalized in the area with the hospitals with above 910 beds per 100,000 people more than in the area with the hospitals with less than 910 beds by 2.0 times. For the accessibility of medical services, government policy should focus on improving the quality of care in local hospitals not on increasing and distributing health care resources.

The purpose of the study was to present basic data of curriculum of PACS (Picture Archiving and Communication System) and to propose improved directions. To research clinical PACS education needs, radiological technologist who related on PACS was surveyed in 12 (55%) of capital area, 6 (27%) of middle area and 4 (18%) of southern area of Korea and for the medical institutes, 8 (36%) of over 1000 beds, 10 (45%) of 500 to 1000 beds and 4 (19%) of less 500 beds. And, to research the status of university education the survey was conducted in 6 of capital area, 6 of middle area and 6 of southern area. As a result, 95.5% of respondents in radiological technologist group thought that giving precede education for PACS and enlarging state-exam would be necessary. In university group, 78% of respondents answered that PACS was equipped and, 82% of them answered that it is very important to study PACS as major. Many universities, however, did not standardize major title and contents so a study about them needs to be followed up.

This research grasped the difference of between the daily medical expenses and the medical expenses reduction rate also the cause of change. In the centre, it was conducted in order to offer the necessary basic data to a recuperation pay management solution's establishment. This research surveyed across the country's urban region 50-general hospital's the infective enteritis disease for a year. Then it was conducted the average daily medical expenses and the average medical expenses reduction rate as a distinguishable survey that is a hospitalization and an outpatient the result is followed. The inpatient daily medical expenses correlated with the total number of medical institution personnel, and the outpatient daily medical expenses correlated with the number of beds.. Inpatient medical expense reduction rate was correlated with number of beds and the total number of medical institution personnel. The interaction between medical institution information and daily medical expenses was found to have a positive (+) effect on the total number of medical institution personnel, as well as the numbers of inpatients vs. outpatient. This research about the medical expense reduction rate and daily medical expense help medical institution's efficient, rational decision making and it will be an important basis of a priority recuperation pay's policy.

This study aimed to determine the management and environmental factors affecting medical expense reduction. For analysis, medical expenses were divided into hospitalization expenses and outpatient treatment expenses, and the rate of medical expense reduction was classified into initial and final reduction rates. Data were collected through a direct survey among 205 directors of independent health insurance review departments of hospital-level medical institutions in Korea. The results of the study are discussed below: In the analysis, differences in the initial and final reduction rates of hospitalization expenses and outpatient treatment expenses were compared. The results showed that, in hospitalization expenses, the initial and final reduction rates were both significantly affected by the following management factors: number of beds, number of departments, number of personnel reviewing health insurance cases, and total number of employees. Further, in outpatient treatment expenses, the initial and final reduction rates were both affected significantly by the following management factors: management of medical records, number of beds, number of departments, number of personnel reviewing health insurance, and total number of employees. The management factors significantly affecting both the initial and final reduction rates were higher number of beds for hospitalization expenses and electronic medical record management for outpatient treatment expenses. The environmental factors significantly affecting both the initial and final reduction rates of hospitalization expenses were a highly cooperative work environment, better implementation of indicator management systems, and overtime pay. Better implementation of indicator management system and a committee for handling medical expenses had significant effects on the initial reduction rate for outpatient treatment expenses. A highly cooperative work environment, better implementation of indicator management system, and overtime pay had significant effects on the final reduction rate for outpatient treatment expenses.

Objectives: The purpose of this study is to estimate the needs of long-term care in S-city Gyeonggi-do according to ADL and IADL. Methods: We surveyed to investigate the needs of 397 study samples which had been selected by stratified randomized sampling, 2.7% in each Dong of S-city. We estimated the disability of elderly by using standards based on ADL and IADL of OECD and Korea Institute for Health and Social Affairs. Results and Conclusions: According to standards of OECD, the elderly with severe disability were 4,712(31.2%). According to standards of Korea Institute for Health and Social Affairs, the severe disabled elderly with helper were 3,776(24.9%) and the severe disabled elderly without helper 2,130(14.1%) So We concluded that the long-term care beds estimated by need were from 2,130 to 4,712. To estimate the long-term care beds, we have to consider together physical, mental, nutrition, and cognition status, existence of helper, helper characteristics, and emotional relationship between elderly and helper. But we considered only disability grades of physical states and existence of helper in this study. So it will be useful to conduct study to consider these other factors in future. At the same time this study is of value to estimate objectively long-term care needs based on physical needs in one region.
