Objectives: Under the fee-for-service system, Korean hospitals have been suffering from the worsening profitability caused by law medical care fees. To overcome the difficulties, they have maximized the quantity of medical services and made relatively large investment in developing new medical services using high-priced medical equipment, medicines and medical supplies which were not covered by medical insurance system rather than reduced running costs. Materials and Methods: This study was made to analyze and forecast the revenue change of the department of Obstetrics and gynecology of an university hospital in Seoul, expecting the implementation of DRG system in 2000. Results: The results were as follows : 1.During the first two days of hospitalization. 41% of total medical service fee was occurred, which was thought that most of the check-ups and operations were made during this period. After two days of hospitalization, the new occurrence of medical service fee tended to reduce. 2.Out of total medical service fee, 67% of admission fee was occurred after 5 days of hospitalization. This was because medical service fees in obstetrics and gynecology department occurred during the first 5 days of hospitalization. 3.Out of fees for operation, treatment, medical supplies and blood transfusion. 71% was occurred during the first two days. 4. In case of fees for examination, 50% was occurred during the first two days. 5.A total of 53% of fees for medication and injection was occurred during the first 5 days. Conclusions: By the implementation of the DRG system, the income is forecast to increase by 800 won to 310,000 won by the disease group of obstetrics and gynecology department. To increase hospital income with the implementation of DRG system, the results of this study suggest that examinations should be done at out-patient departments before the hospitalization of patient, the discharge of patient should be noticed in advance to reduce the period of hospitalization, and admission appointment system should be implemented for the immediate operation and delivery.

Objectives:Since the order for medical treatment as outpatient has begun in Korea, there have been no requests due to the absence of specific details relating to its enforcement and lack of understanding of related specialists. We reviewed current guidelines and administrative conditions for order for medical treatment as outpatient in Korea, and examined examples of operation and related regulations of developed countries. Methods:Korean studies concerning development of the order for medical treatment as outpatient were inquired. We investigated the guidelines of other countries including U.S.A., Australia, United Kingdom and Canada. The survey of related specialists for the improvement of order for medical treatment as outpatient was performed. Results:Related specialists agreed that current order for medical treatment as outpatient needed more detailed guidelines for candidate patients, processes and management for noncompliance. Additionally, majority of the specialists suggested that candidates for order for medical treatment as outpatient should be extended for not only hospitalized patients but also patients in community. Conclusions:We reviewed detailed considerations regarding candidate recipients within current legislation, complemented post-enforcement report, management procedures, and stipulated actions for noncompliance, to be used as practical guidelines for application. More fundamental measures than complementation of guidelines, such as modification of related legislature will be needed to increase usage, and further details with reference to confidentiality of recipients and safety measures and financial support of treatment personnel will be needed.

황종현,유광원,이경행 한국산업식품공학회 2004 산업 식품공학 Vol.8 No.1

To develop a komchi with high sensory quality and storage stability, the optimum pasteurization time and temperature were investigated. Sliced kimchi with different acidity (0.3,0.5 and 0.8%) was prepared and pasteurized at 65 or 75℃, then the microbiological (number of total aerobic bacteria, lactic acid bacteria, and yeasts), physicochemical, and sensory changes were measured. The viable counts of total aerobes, lactic acid bacteria, and yeasts as well as valued of pH and acidity changed rapidly in control. However, the growth of microorpanisms was controlled by pasteurization tratments, and the changes of pH and acidity in the treated kimcji were smaller than those of control, although acidity of the samples was different at the initial state. The sensory results indicated that the overall quality of kimchi samples pasteutized at 0.3 or 0.8% acidity was relatively lower than for samples at 0.5% acidity. particularly, kimchi pasteuriaed at 65℃ were high scored in quality attributes compared to the other samples, with preserving a desirable flavor during whole storage period.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.

Obesity can be defined as a disorder of lipid metabolism and the control of this process is regulated by enzymes involved in lipid metabolic pathway. Obesity is also characterized increases in the number and size of adipocyte differentiated from fibroblastic pre-adipocytes in adipose tissue. The aim of this study was to screen ethanol extracts of 21 fruits and vegetables cultivated in Republic of Korea for identifying natural sources of lipase inhibitor and to investigate the effects of several extracts resulting in suppression of triglyceride (TG) accumulation in 3T3-L1 cells. Among the tested extracts, Diospyros kaki L. showed the highest contents of total sugar and the content of total phenolic compounds was detected 17 species while there was not detected in Ixeris dentate root and Allium fistulosum C. etc. We were screened 26 extracts of fruits and vegetables for pancreatic lipase inhibitory activity compared with orlistat. The strongest lipase inhibitory activities were shown by extract of Allium sativum L. stem, Allium sativum L. bulb, Apteryx australis, Diospyros kaki L. Malus Pumila, Perilla frutescens and Prunus mume regardless of concentrations treated. Eight extracts including Brassica juncea var. integrilolia had no effect on lipase inhibition. During the differentiation of 3T3-L1 preadipocyte to mature adipocyte, the cells were treated with carrier or 7 extracts(1, 5 and 10 ㎍/ml), which was shown to highest lipase inhibitory effects. We were quantified lipid contents secreted mature adipocytes and stained with Oil Red O. All cells treated with the Apteryx australis and Prunus mume significantly decreased TG contents than the control. These findings suggested that the screened fruit and vegetable could be a promising source as the effective and safe lipase inhibitors for isolating bioactive ingredients and developing functional foods.

A strain isolated from soil was able to produce thermostable α-amylase. The strain (KC-101) was identification as Bacillus sp. Bacillus sp. KC-101 was treated NTG(N-methyl-nitro-nitrosoguanidine). The mutant KCM-101 increased α-amylase activity and decreased pretease activity. The condition for production, purification, and properties of α-amylase were investigated. α-Amylase production was maximized when was grown on soluble starch 2.0%, yeast extract 0.5%, K2HPO4 0.1% and MnCl2 0.02% for 24hrs at 37℃, and initial pH 7.0. The enzyme production was also increased by the addition of 0.01% Triton X-100. The enzyme was purified by ultrafiltration(MW 10,000), 80% ammonium sulfate precipitation, and Sephadex G-75 gel chromatography and it's yield 15.0%, The characteristics of purified α-amylase were as follow : MW 55,000, optimal pH and temperature were 7.0 and 95℃, respectively. The enzyme was activated by Ca++ and Mn++ ion but inhibited Co++, Cu++, Hg++, and Pb++ ion. The enzyme was stable at 95℃ and it's thermostability was greatly increased by the addition of Ca++. In kinetic studies, the Km value of α-amylase for soluble starch was 0.93mg/mL.

동기적 검사점 기법에서의 쓰레기 처리 기법

이 논문은 동기적 검사점 기법에서 결함 포용을 목적으로 불안전 저장 장치(volatile storage)에 저장되는 메시지 로그과 안전 저장 장치에 저장되는 검사점의 쓰레기 처리 기법을 제안한다. 기존의 동기적 검사점 기법을 기반으로 한 결함 정보 쓰레기 처리 기법은 가장 최근의 검사점을 제외한 모든 결함 정보를 쓰레기 처리하였다. 하지만 TCP/IP와 같은 신뢰성을 갖는 동기적 검사점 기법이 가장 최근의 검사점만을 복귀 회복 기법에서 사용한다면, 불필요한 복귀(sympathetic rollback)가 발생된다. 이 논문은 동기적 검사점 기법에서 손실 메시지(lost message)를 해결하기 위해 각 프로세스가 동기화된 가장 최근의 검사점외에 검사점이나 메시지 로그를 유지해야 한다는 것을 입증했다. 또한 손실 메시지 해결을 위해 관리되어야 하는 검사점이나 메시지 로그가 쓰레기 처리되어지기 위해 필요한 조건을 새롭게 정의하며, 이 정의를 기반으로 한 검사점과 메시지 로그의 쓰레기 처리 알고리즘을 제안한다. 제시된 조건을 기반으로 한 검사점과 메시지 로그의 쓰레기 처리는 송수신 메시지에 부가된 손실 메시지 관련 프로세스 정보를 이용하므로 쓰레기 처리를 위한 부가적인 메시지를 발생시키지 않는다. 제안된 기법은 일반 메시지가 송수신되기 전까지 쓰레기 처리가 지연되는 '지연 쓰레기 처리 현상(lazy garbage collection)'을 발생시킨다. 하지만 '지연 쓰레기 처리 현상'은 분산 시스템의 일관성을 위배하지 않는다. This paper presents a garbage collection protocol for checkpoints and message logs which are saved on the stable storage or volatile storage for fault tolerancy. The previous works of garbage collections in coordinated checkpointing protocol delete all the checkpoints except for the last checkpoints on each processes. But implemented on top of reliable communication protocol like as TCP/IP, rollback recovery protocol based on only last checkpoints makes sympathetic rollback. We show that the old checkpoints or message logs except for the last checkpoints have to be preserved in order to replay the lost messages. And we define the conditions for garbage collection of checkpoints and message logs for lost messages and present the garbage collection algorithm for checkpoints and message logs in coordinated checkpointing protocol. Since the proposed algorithm uses process information for lost message piggybacked with messages, the additional messages for garbage collection is not needed. The proposed garbage collection algorithm makes 'the lazy garbage collection effect', because relying on the piggybacked checkpoint information in send/receive message. But 'the lazy garbage collection effect' does not break the consistency of the whole systems.

Jong Bum Kim,Won Yu Kang,Se Gwon Moon,Hee Jong Kim,Kyung Hwan Kim,Yeon Hwa Kim,Seung Hwan Hwang,Sun Ho Hwang,Wan Kim 전남대학교 의과학연구소 2012 전남의대학술지 Vol.48 No.1

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), one of the components of Agent Orange,has been reported to be a deadly poison despite its presence at extremely small doses. TCDD is reported to cause various kinds of cancers and other harmful effects on humans. However, a correlation between exposure to TCDD and acute coronary syndrome (ACS) is not yet proven. Thus, we examined the correlation between exposure to TCDD and ACS through an analysis of coronary angiograms from veterans of the Vietnam War. Two hundred fifty-one consecutive men undergoing coronary angiograms owing to ACS between April 2004 and May 2009 at Gwangju Veterans Hospital were analyzed. Included subjects were between 50 and 70 years of age. The patients were divided into two groups: 121 patients who had been exposed to TCDD (Group I)and 130 patients who had not been exposed to TCDD (Group II). Clinical and coronary angiographic findings were evaluated. Baseline clinical characteristics, inflammatory markers, and echocardiographic parameters were not significantly different between the two groups. The incidence of hypertension (71.1% vs. 60.0%, p=0.039) and hyperlipidemia (27.3% vs. 16.9%, p=0.038) was higher in Group I than in Group II. Total occlusion,stent length, stent use, and coronary lesion characteristics were not significantly different between the two groups. The rate of major adverse cardiovascular events (MACE) had no relationship with exposure to TCDD. Exposure to TCDD might not affect severity or the rate of MACE in persons with ACS.
