Off-flavor in foods or raw materials have been concerned. Reduction methods of offflavor in foods such as raw materials of soybean paste, meat and fishery were studied through literature review. In order to reduce off-flavor several methods were tried such as masking or binding of off-flavor, improving cooking process, inhibiting rancidity, and inactivation of undesirable enzyme. Nutritional aspect and its safety should be considered but the approach to overcome the problem was not scientific and systematic. In this study systematic approach was accomplished and analyzed for reducing off-flavor and to improve flavor of foods and raw material. It would be useful for applying masking or binding of off-flavor, improving cooking process, inhibiting rancidity, and inactivation of undesirable enzyme for reduction of off-flavor in Korean foods as well as new product development.

Purpose: The present study purposed to compare the hand washing effect of 7.5% powidone-iodine, which is used in the operation room of C university hospital in Seoul, with that of Ethyl alcohol-CHG mixture recommended by the US Association of Operating Room Nurses (2002) and to adopt a more effective hand disinfectant. Method: In a quasi-experimental design, 48 medical staff who participated in operations during the period from November 2004 to February 2005 had hand washing using the two kinds of hand disinfectants: 7.5% povidone-iodine and the ethyl alcohol-CHG mixture. Their palms were swabbed and cultured just after hand washing and again after taking dff sterile gloves after the operation. The number of colonies from the two occasions were counted and compared. Result: The number of general bacillus increased significantly in the group using 7.5% povidone-iodine compared to that in the group using the ethyl alcohol-CHG mixture. The number of general bacillus increased signficantly in doctors compared to that in nurses. The factors affecting the increase of the number of general bacillus were disinfectants and medical personnel. The number of general bacillus was expected to increase 9.41 times with 7.5% povidone-iodine than with the ethyl alcohol-CHG mixture and 14.87 times in doctors than in nurses. Conclusion: This study shows that the ethyl alcogol-CHG mixture has a stronger hand disinfection effect than 7.5% povidone iodine. Thus we need to change the hand disinfectant used in operating rooms as soon as possible in order to minimize the infection of wounds resulting from operations.

Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

응급환자의 중증도 분류를 위한 지표의 개발 : Triage Score와 Modified Triage Score NEW METHODS TO TRIAGE ALL EMERGENCY PATIENTS

임경수,홍은석,김선만,황성오 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

Up to now, triage system for all emergent patients, which can be used fast and conviently according to their severity has not been developed yet. For the triage of trauma patient, emergency medical technicians and emergency medical doctors are commonly using R.T.S. (Revised Trauma Score). The R.T.S. consists of GCS(Glasgow coma scale), systolic blood, pressure and respiration rate per minute. But it is difficult for emergency medical technicians to calculate GCS in the prehospital because of its complexity and need for more time. Therefore we develop the Triage Score by remodelling the R.T.S. by replacing GCS with AVPU scale and systolic blood pressure that is under 49 mmHg after adding 1-49 mmHg with 0 mmHg and respiration rate per minute that is under 5/min after adding 1-5/min with 0/min. We stuied the significance and the possible triage application of Triage Score in traumatic emergency patients. For nontraumatic emergency patients, we develop the Modified Triage Score to triage the cardiovascular emergencies by adding the item of chest pain to Triage Score. A prospective study was carried out on 530 patients from March 1 to 31 1996. There were 210 trauma patients and 320 nontraumatic emergency patients and the result shows as follows. For trauma patients, there was linear correlation between R.T.S. and Triage Score(R²=0.965). Comparison analysis between high risk group (admission+death patients) and low risk group(discharge patients) of nontraumatic emergency patients by using Modified Triage Score is statistically significant(P<0,001) The cardiovascular emergencies could not categorized as urgency by Triage Score, but that was possible by application of Modified Triage Score. In conclusion, we can triage the injured patients effectively by Triage Score and the nontraumatic emergency patients including emergency cardiovascular disease can be categorized as urgency by applying the Modified Triage Score.

원관 주위의 대류 열전달에 대한 원둘레 방향의 열전도의 영향

이승홍,이억수,정은행 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.53 No.-

원관축의 수직방향으로 유체가 유동하는 경우에, 가열되는 수평 원관 주위에서 원둘레 (θ)방향으로 비대칭적으로 균일하지 않게 온도가 분포하기 때문에 원둘레 방향으로의 전도 열전달이 존재하고 비균일 대류 열전달 현상이 생긴다. 본 연구에서는 공기와 물을 작동유체로 하고 직교 유동내에 있는 수평 원관의 열전달 실험에서 국소 대류 열전달에 대한 원둘레 방향 열전도의 영향에 대하여 연구하였다. 에너지 방정식에서 유도된 무차원 수가 반경방향에 대한 원둘레 방향의 열전도의 영향을 나타내는 무차원 수로 사용되었다. 4가지 모델을 직접 전기저항 가열방식으로 가열하고, 원관 표면의 온도를 직접 측정하여 2차원 온도분포의 경계조건으로 사용하여 원관의 단면 내부에서 2차원 온도분포 T(r,θ) 를 보여준다. With uniform heat generation in a horizontal cylindrical heater placed in a cross flow boundary condition, heat flow that is conducted along the wall of the heater creates a non-isothermal surface temperature and heat flux distribution. In the present investigation, the effects of circumferential wall heat conduction on convection heat transfer is investigated for the case of forced convection around horizontal cylinder in cross flow of air and water. Non-dimensional conjugation parameter which can be deduced from the governing energy differential equation should be used to express the effect of circumferential wall conduction heat transfer. Two-dimensional temperature solutions T(r,θ) distribution is presented. The influence of circumferential wall heat conduction is demonstrated on graph of local Nusselt number.
