Objectives The purpose of this study was to revitalize pediatric emergency care in oriental medical hospital. Methods The study was composed of 281 pediatric patients who visited emergency room of the ${\bigcirc}{\bigcirc}$ university oriental hospital, from March 2006 to February 2007. Results The age distribution showed that 1 to 3 year's patients(40.6%) are the most New pediatric patients(59.1%) were more than who received medical treatment in this place. The seasonal distribution of between month's section and the 24 solar terms's section made no differences and pediatric patients who visited in emergency room was most in spring, least in autumn. Moreover the changes of season's patients were more than others. Pediatric patients who visited during the weekends and holidays(50.9%) were more than during the weekdays(49.1%). Systemic division of the major problems were the digestive symptoms(44.5%) and nervous symptoms(30.6%), respiratory symptoms(12.5%), musculoskeletal symptoms(5.3%), dermatological symptoms(1.8%), cardiovascular symptoms(0.7%) and others(4.6%) followed. The time interval between arrival and onset : within 6 hours were the most(54.5%). Pediatric patients who had digestive, nervous, musculoskeletal diseases within 6 hours were the most, but in the case of patients who had respiratory diseases, most of them were visited within 48 hours. Acting and herb-med treatment(77.9%) were the most in medical treatments. Pediatric patients(69.0%) who didn't revisit in this hospital after treatment in emergency room were more than who revisited(29.9%). Conclusions Pediatric patients who visited in emergency room of oriental medical hospital were most not acute form of a serious diseases, patients most visited in disease prefer to oriental medicine; such as dyspepsia, convulsions, crying, ankle sprain.

Objectives: This study aims at decreasing spatial dose rate through work improvement whilst spatial dose rate is the cause of increasing personal exposure dose which occurs in the process of handling radioisotope. Methods: From February 2013 until July 2013, divided into "before" and "after" the improvement, spatial dose rate in laboratory of nuclear medicine was measured in gamma image room, PET/CT-1 image room, and PET/CT-2 image room as its locations. The measurement time was 08:00, 12:00 and 17:00, and SPSS 21.0 USA was opted for its statistical analysis. Result: The spatial dose rate at distribution worktable, injection table, the entrance to the distribution room, and radioisotope storage box, which had showed high spatial dose rate, decreased by more than 43.7% a monthly average. The distribution worktable, that had showed the highest spatial dose rate in PET/CT-1 image room, dropped the rate to 42.3% as of July. The injection table and distribution worktable in the PET/CT-2 image room also showed the decline of spatial dose rate to 89% and 64.4%, respectively. Conclusion: By improving distribution process and introducing proper radiation shielding material, we were able to drop the spatial dose rate substantially at distribution worktable, injection table, and nuclide storage box. However, taking into account of steadily increasing amount of radioisotope used, strengthening radiation related regulations, and safe utilization of radioisotope, the process of system improvement needs to be maintained through continuous monitoring.

In order to see the effects of talker sidetone on a talker's speech level quantitatively when he converses with others on a telephone, we reviewed the measuring algorithm of speech level and assessed variation of speech level due to that of sidetone masking rating(STMR). We measured room noise effects on speech level, when STMR values were changed, as well. If we consider the effects of talker sidetone and room noise on speech level, the results of experiments suggest that a talker continuously tries to keep the psychological loudness of his own speech, heard by himeself via a telephone handset, at the constant and comfortable level by controlling his speaking level according as STMR value and room noise are change. That is, because the amount of his speech masked by his talker sidetone and room noise is different when STMR value and room noise are changed, we can see the tendency that he controls his speaking level in order to keep the perceived psychological loudness of his own speech to be constant.

The purpose of this study is getting information for making a plan of immigrant workers in Korea. As a first step to suggest plans for immigrant workers who have multi-cultural background, this study investigated to the domestic living of Koreans(ChoSun-Tribe) of Gillim province in China. For this, usage of domestic space questionnaire were used. Results of the research were as follows. 1. The most popular LDK type was the one which kitchen was separated from living room and dining room. Most of them thought that kitchen and living room have to be separated. 2. There was no plan for laundry room specially and most houses have a washing machine in the bathroom. Most houses didn't install a bathtub in the bathroom and they didn't think that it was indispensable. 3. It was estimated that they used a living room as a multi-purpose room for the family but used a master bedroom for its own purpose. 4. They used a table and chair for meals normally but they took meals sitting on the floor with a large family or guest. 5.All of them took off the shoes inside of the house for hygienic reason. There was no plan for the space to take on-off shoes in most houses and they just put the mat on the floor for it. 6. Modified Ondol system which use water pipe under the floor was popular in apartment while most detached houses had traditional Ondol system. The satisfaction about Ondol system was very high compared to other ones and also Ondol system was the most desirable one for ChoSun-Tribe.
