This study was conducted to investigate and to improve the actual condition of food service for patients in hospitals. For this purpose, questionnaires were distributed to 283 patients admitted to a university hospital and three general hospitals between January 27 and February 15, 1997. The department participated in the study included internal medicine, surgery, obstetrics, orthopedics and so forth. For meal time, 61.1$\%$ of patients wanted to eat breakfast at 8 am, 55.8$\%$ lunch at noon, and 73.5$\%$ dinner at 6 pm. The patients complained about unsatisfactory hospital food itself by 37.8$\%$, about insufficient food amount by 19.6$\%$, about menu with no choice by 41.2$\%$ and about low variety of the meals by 32.7$\%$. Sixty two point nine percent of the subjects enjoyed snacks between meals because of poor appetite at meal time(46.1$\%$), delayed food service(39.9$\%$) and others(11.2$\%$). The types of diet were mainly regular ones(58.6$\%$) with some high protein(12.4%) and diabetic sensitive ones(7.1$\%$). As eating place, the patient's prefered bed(51.9$\%$), room-table(27.2$\%$) and dining room(17.7$\%$). Fifty-five percent of them also wanted hospital foods available to their caring relatives.

일시 출입자로 분류된 핵의학과 출입 환경미화원은 주기적으로 타과와 업무순환을 하고, 또한 작업 시간과 환경 등의 변화가 많기 때문에 관리하기에 어려운 점이 있으며 따라서 이들의 분류를 명확히 할 필요가 있다. 이에 본 논문에서는 핵의학과에서 근무하는 환경미화원의 피폭 상황을 분석하여 일시 출입자로 분류된 조건의 타당성에 대하여 검토해 보고 작업 환경의 변화 및 근무 시간의 조절이 필요한가를 알아보았다. 우선 먼저 PET실과 혈액 검사실에서 근무하는 환경미화원과 감마 카메라실에서 근무하는 환경 미화원 2명을 대상으로 한 달간 근무 시간 중에 OSL을 각각 착용시켜 개인 피폭 선량을 측정하였다. 둘째로 survey meter를 이용하여 두 명의 환경미화원의 작업 환경, 근무 형태에 따라 시간대 별로 핵의학과 내 14개 구역을 선정, 총 10회 공간 선량률을 측정한 결과 이들의 피폭 선량은 연간 1mSv를 초과하지 않았으며, survey meter를 이용하여 조사한 결과 또한 연간 1 mSv를 초과하지 않을 것으로 추정되지만 그 수치가 1 mSv에 근접하였다. 따라서 일시 출입자로써의 분류를 좀 더 명확히 하기 위해서는 PET 안정실과 같은 피폭이 상대적으로 많은 구역에서의 노출 확률을 줄이기 위하여 이들에게 방사선 관리 구역내 교육을 실시하고, 또한 근무시간 및 근무 형태를 적절히 변경한다면 이들의 피폭 선량은 확연히 줄어들 것으로 사료된다.

An eipdural hematoma in an infant is a very rare entity. We report a case of an acute traumatic intracranial epidural hematoma that developed with a lucid interval in a 4-month-old infant after a fall down from a bed. The infant was admitted at the emergency room. The child had initially cried and may have had a decreased level of consciouseness due to brain injury, but then returned to normal level of consciousness for several hours prior to admission. However, the infant had vomited twice after taking milk and then was lethargic. The brain CT revealed a lentiform-shaped huge hematoma on the right parietal area with a midline shift of 8 mm. An osteoplastic craniotomy was performed, and the intracranial epidural hematoma was totally removed. Postoperatively, the infant recovered well and was dischaged.

The purpose of this study were to investigate the bed climate and the physiological responses in sleep on the traditional Korean floor heating system called Ondol. Ondol has been the most widely used heating system in Korea, yet there has been a no systematic studies examined its environmental effects on human body. Experimental room was constructed to match the typical thermal environment of Ondol. (floor surface temperature; $32\~33^{\circ}C$, air temperature; $22.5{\pm}1.0^{\circ}C$, relative humidity; $64.0{\pm}4.0\%$RH, air velocity; 0.25 m/sec.) Three different combinations of bedclothes were chosen for the experiment based on the study results showing that they were the most widely used types in Korea. Type 1 was the combination of a cotton-padded mattress with a cotton-padded Korean style blanket. Type 2 was a cotton-padded mattress with a cotton-guilted Korean style blanket. Type 3 was a cotton-padded matless with a polyacryl blanket. Thermal resistance of each of these combina-tions in the bedclothes was measured using thermal manikin. Two adult female was chosen for the seven hour sleeping experiment which was known to be the average sleeping hours of Korean adult female. The bed climate was measured with the temperature under the mattress, the surface temper-ature of the mattress, and the air temperature and the relative humidity of the space between the mattress and blanket. The skin temperature, rectal temperature of the subjects and the bed climate were measured eight times, one hour before the experiment and every hour during the experiment. The weight loss and the subjective sensation were measured for the each subjects before and after the experiment. The procedure was repeated twice with two subjects and three types of bedclothes, yielding twelve combinations of results. The results were as follows; 1. With the surface temperature of $32\~33^{\circ}C$ of Ondol, air temperature was $22.5{\pm}1.0^{\circ}C$ with $64.0{\pm}4.0\%$ RH. The bed climates were $39.2{\pm}40.8^{\circ}C$ under the mattress, $35.3\~36.2^{\circ}C$ on the mattress, and $26.9\~32.0^{\circ}C$ with $56.0\~71.3\%$ RH between the mattress and the blanket. 2. Mean skim temperature during sleep was 34.2"C with local skin temperature of $34.0\~35.5^{\circ}C$. The skin temperatures of abdomen, thigh, foot were higher than the other parts of the body. 3. The skin temperature of chest, thigh, leg and back varied significantly according to the combinations of bedclothes. With the cotton-padded blanket, the skin temperature was the highest, while with the cotton-guilted blanket showed lowest. 4. Examining the relationship between the mean skin temperature and the local skin temper-ature, the chest temperature showed the highest correlation with the former. Therefore, the chest temperature can be recommended to represent the skin temperature in measuring the bed climate. 5. The subjective bed climates were $39.0\~40.4^{\circ}C$ under the mattress, $35.2\~35.9^{\circ}C$ on the mattress, $29.8\~31.6^{\circ}C$ with $56.8\~68.4\%$ RH between the mattress and blanket. In sum, from this experiment we not only obtained the reliable value of bed climates on Ondol, but also showed that the bed climates and the physiological responses were affected differently according to the materials of bed clothes.

The performance of fluidized-bed reactor with Photomedia, immobilized TiO$_2$ onto the porous ceramic ball using a sol-gel method has been studied in this work. A simple model substrate, dilute Rhodamine B (RhB), was decolorized at room temperature. For the purpose of comparison, the slurry reactor and the Inner Wall Coated Reactor (IWCR) were used. The aim of this work was to develop the photocatalytic fluidized bed reactor (PFBR) through contrasting the photodegradability of various reactors such as the TiO$_2$slurry reactor, the inner-wall coated reactor (IWCR). In this study, the RhB was decolorized in three types of reactor. Even though the reaction rate constant of PFBR was lower than that of slurry reactor, PFBR had the advantages of preventing the wash-out of photocatalyst, so it can be operated continuously.

This study was performed to investigate the current status of isolation precautions of multidrug resistant organisms(MDROs) in general hospitals with more than 200bed. The questionnaires were mailed from 3rd, April 2013 to 30th, April 2013. Methicillin resistant Staphylococcus aureus:(MRSA), vancomycin resistant Staphylococcus aureus:(VRSA), vancomycin resistant Enterococcus(VRE), multidrug-resistant Acinetobacter baumannii, carbapenem-resistant Enterobacteriaceae multidrug-resistant Pseudomonas aeruginosa were enrolled. MRSA(100.0%) and VRE(98.7%) were isolated respectively. VRE(97.3%) and MRSA(64.0%) were regulated strictly respectively. VRE(91.5%) and VRSA(50.7%) were isolated in a single room respectively. Hospital being located in Seoul(p<0.001), and beds(${\geq}600$)(p=0.008) were different significantly. The isolation space limitation(71.1%) was the highest difficulty. The development of refunding the costs of the extra supplies and other hygienic materials for infection control was discovered as the most urgent strategy.
