유통과정에서 균질한 저온을 유지하는 것은 식품의 유통기한을 결정하는 가장 중요한 요소 중 하나인 미생물 증식을 억제하는 핵심 기술이다. 신선수산물의 전과정에서 정확하고 적절한 온도관리가 보장되었을 때 높은 품질의 신선 제품을 소비자에게 공급할 수 있다. 이 논문은 슈퍼칠링 신선수산식품의 상업성을 확인하기 위하여 포장된 신선 광어(Paralichthys Olivaceus) 의 유통기한을 연구한 것이다. 유통기한 측정을 위하여 중량, 대장균 등 세균수, pH, 관능검사, 색상, 휘발성 염기질소 등이 조사되었다. 연구결과, 휘발성염기질소를 기준으로 슈퍼칠링 온도(0±1℃)에서의 유통기한이 6일인데 비하여 일반 냉장온도 (8±2℃)의 경우 1일에 불과하여 슈퍼칠링 유통의 가능성을 보여주었다. 상업화 추진을 위해서는 소비자 신뢰도를 높이고 경제성을 향상시킬 수 있도록 슈퍼칠링 기법과 포장시스템에 대한 추가적인 포장방법 연구가 필요한 것으로 사료된다. Maintaining steady and low temperature during distribution process is a key technique to inhibit microbial growth, one of the most important factors in determining the shelf life. It is possible to provide high-quality fresh products to consumers only when precise and adequate temperature control is guaranteed throughout the entire distribution process for fresh seafood. This study investigated the shelf-life of packaged fresh flounder (Paralichthys Olivaceus) in order to learn the feasibility of super-chilled distribution of fresh seafood. To estimate the shelf life, weight, number of bacteria such as E. coli, pH, sensory test and volatile basic nitrogen were investigated. As a result of the study, the difference in shelf life of 6 days at the super-chilling temperature (0±1℃) and 1 day at the general refrigeration temperature (8±2℃) (based on volatile base nitrogen) showed the market possibility of super-chilling distribution. Through additional empirical studies such as packaging methods and economic feasibility, it is expected to promote commercialization of super-chilling containers and packaging system developed in the future and secure customer reliability.

N/A Background: Quality of postoperative care may be improved by management of postoperative pain. Epidural anesthesia and analgesia have several advantages over general anesthesia and parenteral analgesics in managing the postoperative pain. We retrospectively reviewed records of obstetrical patients who underwent the cesarean sections under epidural anesthesia to evaluate perioperative analgesic use, side effects, and complications. Methods: All patients received epidural anesthesia consisting of 0.25% bupivacaine, 2% lidocaine and 100 μg fentanyl, followed by epidural analgesia with 0.1% bupivacaine and 12.5 μg/ml fentanyl at rate of 2 ml/hr for 48 hours. Patients records were reviewed for: medications administered for pain relief, incidence of nausea and vomiting and pruritus, and presence of respiratory or cardiovascular depression. Results: Over 18 months, 1,054 patients' records were reviewed. Average age was 27.8 years (18-43 years). 768 patients (72.9%) received no additional drugs for the pain relief. Intramuscular analgesics, ketoprofens, were one time administered to 247 patients (23.4%), 39 patients (3.7%) received two more dosages. The time of administration was 8.3+4.3 hours postoperatively. Antiemetics, for example, low-dose droperidol, were administerd one time for 160 patients (15.2%), 5 patients (0.5%) received two or more administrations. The medication was administered 5.1+4.2 hours postoperatively. Drugs for relief of pruritus, low-dose naloxone, were administered one time for 108 patients (10.2%), 10 patients (0.9%) received 2 or more dosages. The time of administration was 6.3+4.2 hours postoperatively. None of the patients experienced cardiovascular nor respiratory (<8 breath/min) depression. Conclusions: Postoperative continuous epidural analgesia in combination with bupivacaine and fentanyl is an effective method of providing postoperative analgesia with low incidence of side effects.

Purpose: The purposes of this study were to examine sleep hygiene and sleep quality and to identify factors that influence sleep quality among community dwelling elders. Methods: A descriptive correlational study was conducted. Participants were 105 community dwelling elders from a metropolitan city. Data were collected using structured questionnaires and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression analysis. Results: Sleep hygiene of participants was generally good. Sleeping quality was somewhat poor and the most frequently mentioned sleep disturbance was waking up to use the bathroom. Sleep quality was significantly correlated with instrumental activities of daily living, depression, and sleep hygiene. Health status, sleep hygiene, and education level were statistically significant predictors of sleep quality and these three variables accounted for 26.7% ofvariance in sleep quality. Elders in good health, with good sleep hygiene and a higher education level expected a better quality of sleep than their counterparts. Conclusions: The results of this study indicate that educational interventions are needed to increase quality of sleep among community dwelling elders. Good sleep hygiene practices are necessary to increase sleep quality. Sleep promotion intervention programs for community dwelling elders should be developed and evaluated.

The majority of total ingested fluoride is obtained from dietary source and dental products in nonfluoridated areas. Since the dietary fluoride intake of Korean young children and adults is not known, a study was designed to determine the dietary fluoride intake of 2-4-year-old children and 28-39-year-old females residing in nonfluoridated Seoul. Parents of 25 young children and 23 female adults duplicated quantitatively and qualitatively all foods that the young children and females ingested during 24-hours. Homogenated food samples were ashed, and then fluoride was isolated by the hexamethyldisiloxane diffusion method during 24 hours. And fluoride ion concentration was measured with an ion-specific combination fluoride electrode. Daily fluoride intakes of female adults and young children were calculated, and estimated from standard diet table. The obtained results were as follows 1. Dietary fluoride intake of female adults was 1.260±0.366㎎/day and the intake of young children was 0.650±0.220㎎/day. 2. Mean daily dietary fluoride intake of young children was 0.046±0.016㎎/day body weight. 3. Estimated dietary fluoride intakes from standard diet table were 1.538㎎/day for female adults, 2.091㎎/day for male adults and 0.759㎎/day for young children. 4. Dietary fluoride intake of Seoul citizens was less than the recommended intake for dental caries prevention. Therefore, it is recommended that community water fluoridation be implemented in Seoul.

Background : Video-assisted thoracic surgical procedure via thoracoscopy has recently gained popularity, as it avoids a thoracotomy, reducing intraoperative blood loss, postoperative pain, respiratory dysfunction and hospital stay. However, to visualize adequately the intrathoracic structures, creation of artificial pneumothorax by carbon dioxide insufflation during thoracoscopy would cause significant hemodynamic compromise. The aim of this study was to evaluate the effect of CO2 insufflation into the pleural cavity on the hemodynamics and the arterial blood gas tension under general anesthesia. Methods : Twenty-five patients, after intubation with single lumen endotracheal tube, underwent enflurane (1∼2%) and N2O-O2 (1:1) general anesthesia. Before placement of a thoracoscope, the baseline mean arterial pressure and heart rate were obtained. Measurements were taken at 5, 10, and 20 min. after the beginning of carbon dioxide insufflation (3∼5 mmHg) and 10 min. after gas evacuation. Blood gas analyses were done before, during CO2 insufflation and after CO2 evacuation. Data were analyzed using Student t-test. Results : Positive-pressure CO2 insufflation (3∼5 mmHg) caused a decrease of mean arterial pressure (5∼7%) and an increase of airway pressure (1.5 times) and heart rate (13∼20%) throughout the gas insufflation period(p$lt;0.05). Blood gas analyses revealed no significant change. Conclusions : These results suggest that low CO2 insufflation pressures (3∼5 mmHg) may cause cardiovascular depression during thoracoscopy. Therefore careful monitorings should be done during this procedure. (Korean J Anesthesiol 1998; 34: 98∼102)
