붕장어 가공부산물인 머리와 frame를 효율적으로 이용하기 위한 일련의 연구로 붕장어 부산물을 이용한 붕장어탕의 개발을 시도하였고, 아울러 이의 식품성분 특성에 대하여도 살펴보았다. 살균조건 및 가온일수에 따른 붕장어탕의 저장성 부여를 위한 최적 살균조건은 F? value=8분으로 판단되었다. 붕장어탕의 일반성분은 수분의 경우 90.7%, 조단백질의 경우 4.8%, 조지방의 경우 2.6%, 조회분의 경우 1.5%를 나타내었다. 붕장어탕의 엑스분 질소 함량은 243.1 ㎎/100 g으로 시판 추어탕의 208.0 ㎎/100 g보다 높았다. 붕장어탕의 총 아미노산 함량은 4,310 ㎎/100 g이었고, 주요 구성아미노산은 glutamic acid(637.3 ㎎/100 g, 14.8%), glycine(409.1 ㎎/100 g, 9.5%) 및 alanine(404.4 ㎎/100 g, 9.3%)등이었다. 붕장어탕은 관능적인 비린내는 거의 감지되지 않았고, 맛은 우수하였으며, 항산화능이 인정되었으나 ACE 저해능은 크게 기대할 수 없었다. For the effective use of the conger eel by-products, such as head and frame, Tang, which is the Korean-type soup, from conger eel by-products (TCEB) was developed and its food component characterization was compared with that of commercial Chueotang, loach Tang. According to the results of viable cells and coliform group of TCEB heated at 115oC for various times, the reasonable F0 value was 8 min. The proximate composition of TCEB was 90.7% for the moisture, 4.8% for the protein, 2.6% for the lipid, and 1.5% for the ash. The extractive-nitrogen content of TCEB was 243.1 ㎎/100 g, which was higher than that of commercial Chueotang, 208.0 ㎎/100 g. The total amino acid content of TCEB was 4,310 ㎎/100 g and its major amino acids were glutamic acid (637.3 ㎎/100 g, 14.8%), glycine (409.1 ㎎/100 g, 9.5%) and alanine (404.4 ㎎/100 g, 9.3%). TCEB was not felt in the sensual fish odor and its sensual taste was good. The health functional properties for health of TCEB were 1.29 as a PF (protection factor) for antioxidative activity and 39.4% for angiotensin Ⅰ converting enzyme (ACE) inhibiting activity.

This study investigated the effect of aerobic exercise training on immune cell proliferation and inflammatory cytokine production in the spleen of high fat diet-induced obese mice. C57B1J6 male mice (4 weeks aged. n20) were fed a high fat diet (45% fat) for 5 weeks so that obesity was led intentionally. Then, these obese mice were divided into 2 groups: control group (CON. n10) or exercise group (EXE, n=l0). EXE performed treadmill running for 30-60 min/day at 10-22 m/min, 0% grade, five times per week for 8 weeks. After 13 weeks, all the splenocyte was collected and Con A (Concanvalin A 10 ㎍/ml) was used to stimulate the cell proliferation. MTS and BIOPLEX assay were used for cell proliferation and cytokine production. Independent t-test was used and a p-value under 0.05 was considered as statistically significant. In the results, body weight, IL-2 and IL-6 production were significantly reduced and Splenocyte proliferation was significantly increased after 8 weeks of exercise training. These findings suggest that aerobic exercise training has a positive effect for improving the obese-induced immune dysfunction.

피부를 탄력있고 부드럽게 하는 역할은 각질층에 존재하는 수분량에 의해 좌우된다. 피부 수분량은 냉온풍, 건조환경 등 다양한 환경 변화에 의해 영향을 받음이 알려져 있으나, 개인 피부 차이에 따른 피부수분량 변화와 회복 정도에 대해서는 많은 연구가 이루어 지지 않은 실정이다. 본 연구에서는 온풍 조건하에서 피시험자들의 피부 수분 탈락 및 회복 정도를 비교 평가하여 새로운 피부 타입을 제시하고, 온풍 조건에서 저하되는 피부 수분량을 개선 시켜주는 효능 물질을 개발하고자 하였다. 온풍 환경 조성을 위해, 건강한 피험자(남: 10 명, 여: 39 명, 25 세 - 63 세)의 전완부에 온풍(30 cm, 40 ℃, 6 m/s)을 30 min 간 피부에 노출시켜, 피부 수분량의 변화를 평가하였다. 26명(남: 4 명, 여: 22 명, 평균 연령: 42.7 ± 9.4)이 온풍 노출전에 비하여 온풍 노출 후 수분량이 유의하게 감소하며, 노출 후 30 min이 지나도 회복이 되지 않았다. 온풍노출 후 수분량이 떨어지는 피험자(여: 10 명)를 대상으로 보수력이 높은 크림을 3 주간 전완부에 적용한 이후 동일 온풍 조건하에서 피부 수분량을 측정한 결과, 노출 30 min 후 피부 수분량이 온풍 노출 전 수준으로 회복됨을 확인하였다. 본 연구를 통하여 피부는 건조 조건에서 쉽게 수분을 잃어버리는 피부(탈수형 피부)가 존재하는 것을 확인하였다. 이는 앞으로 화장품 개발을 보습 기능뿐만 아니라, 이러한 환경변화에 따른 피부수분이 쉽게 빠져나가는 피부(탈수형 피부)의 특성에 맞는 제품의 효능 개발이 필요함을 보여준다. Elasticity and softness of the skin depend on the level of moisture present in the stratum corneum, which is known to be affected by various environmental changes, such as cold and hot winds and dry environments. However, not many studies have been conducted on changes in skin moisture and the degree of recovery due to individual skin differences. In the present study, we aimed to investigate the effect of warm air heating on skin hydration levels and develop moisturizing formulas to improve lowered skin hydration levels. In order to deliver warm air heating condition, heating dryer (40 ℃, 6 m/s, 30 cm apart from forearm) was applied into inner forearm of healthy subjects (male: 10, female: 39, age: 25 - 63) Among 49 subjects, 26 subjects showed significantly lowered skin hydration levels until 30 min after warm air heating exposure (lowered group). In addition, moisturizing cream with high water holding capacity was applied to forearm of 10 subjects in lowered group for 3 weeks and skin hydration levels after warm air heating were significantly improved at the levels of before application of warm air heating. From this study, we found out that there is a skin type that skin hydration levels are significantly decreased under warm air heating condition (dehydrated skin) and this dehydrated skin can be improved by moisturizing formulas with high water holding capacity.

To study the pseudocholinesterase acticity and its clinical significance in patients with acute organophosphate poisoning, Authors checked the serum cholinesterase activity in 49 normal subjects and 31 acute organophosphate poisoned patients. The results were followings. 1. The mean pseudocholinesterase activity f normal subjects was 1271 IU/L in male and 1131 IU/L in female. The total mean cholinesterase activity was 1209/ IU/L. 2. The pseudocholinesterase activity of patients were significantly reduced compare to normal. 22 patients(73%) were below 10% of normal, 6 patients(20%) were between 10-20% of normal and only 2 patients (7%) were between 20-50% of normal. 3. As a whole there was more depressed cholinesterase activity in patients with comatous and drowsy mentality, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference presented. 5. The mean arterial blood gas checked on arrival was pH 7.386, PaO?? 66mmHg, PaCO?? 38mmHg 02 Saturation 91%. There was noted no statistically significant correlation between pseudocholinesterase activity and these parameters. 6. The pseudocholinesterase activity on the 1st day of admission was 5.7% of normal and progressively increased during admission. On the 14th day of admission, the pseudocholinesterase activity was 35.5% of normal and it takes 20 days to reach 50% of normal. Authors concluded that serum cholinesterase activity of acute organonphosporus poisoned patients were markedly depressed and progressively increased during admission. As a whole the pseudocholine-sterase activity seemed to be related to the clinical findings but no statistically significant difference was found.

Recently increasing amount of efforts has been devoted to the improvement of logistics in the marine products industry. Yet, few studies have been conducted on the development of site selection models of marine products centers. This paper proposes a systematic assessment model for the decision making, which is composed of a set of evaluation criteria and an appropriate evaluation method. In choosing criteria we consider completeness and comprehensiveness to reach a right solution. For more flexibility of the model in the future, this study proposes two sets of criteria according to the size of planned centers. The Analytic Hierarchy Process (AHP) is adopted in this study, since the criteria incorporate both subjective factors and objective factors and the AHP is known effective in the situation. This study then illustrates the model application with plausible alternatives. Finally, a dependency problem in the decision criteria is discussed and the Analytic Network Process (ANP) is recommended, in the context, as a solution method.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

We extend the sue of the method of least square to develop a recursive algorithm for the design of adaptive transversal filters such that, given the least-square estimate of this vector of the filter at iteration n-1, we may compute the updated estimate of this vector at iteration n upon the arrival of new data. The RLS algorithm may be viewed as a special case of the Kalman filter. Indeed this special relationship between the RLS algorithm and the Kalman filter is considered. We begin the development of the RLS algorithm by reviewing some basic relations that pertain to the method of least squares. Then, by exploiting a relation in matrix algebra known as the matrix inversion lemma, we develop the RLS algorithm. An important feature of the RLS algorithm is that it utilizes information contained in the input data, extending back to the instant of time when the algorithm is initiated. The resulting rate of convergence is therefore typically an order of magnitude faster than the simple LMS algorithm. This improvement in performance, however, is achieved at the expensive of a large increase in computational complexity

Skeletal cryptococcosis is an uncommon infection. Cryptococcus is a common cause of meningitis and infects 7∼10% of patients with AIDS. As well as AIDS, the infection may be seen in association with leukemia, lymphoma, Hodgkin's disease, sarcoidosis, tuberculosis and diabetes, also in patients on steroid medication. But there is no case report of skeletal cryptococcosis following allogeneic hematopoietic stem cell transplantation. A 40-year-old woman was admitted to the hospital because of low back pain. She had chronic myelogenous leukemia for 2 years and underwent allogeneic hematopoietic stem cell transplantation 8 months ago. She have been treated with steroid and cyclosporine orally because of chronic graft versus host disease. On examination she was afebrile and had posterior lower lumbar tenderness. But, she had no reduced strength of low extremities. Open biopsy was underwent. Histology demonstrated budding, round-to-oval, refractile yeast-like organisms within debris. The results of a lumbar puncture were unremarkable and cerebrospinal fluid culture failed to grow bacteria and yeast. The patient was treated with amphotericin B (1 gram) and AmBisome□ (2.8 gram) over 6 weeks. Three months after cessation of therapy, the patient was doing well.(Korean J Infect Dis 33:298∼301, 2001)

This is a series of continuing research on facial bone fractures of Koreans worked by Dept. of Oral and Maxillofacial surgery, Dental College of Yonsei University, Seoul, Korea, since 1972. The study was based on a series of 630 patients with facial bone fractures treated as in patient at Yonsei Medical Center, Yonsei University, during the period of Jan. 1982 through Dec, 1987. The results obtained are as follows: 1. The ratio of Men to Women was 4.3 : 1, and admissions for facial bone fractures have been increased year after 1984. 2. The age frequency was highest in the third decade(38.3%). and fourth, second, fifth decade in orders. 3. The traffic accident was the most frequent cause of facial bone fractures(51.3%). 4. The most common location of facial bone fractures was the Mandible(35.3%), and Zygoma complex(29.8%), Nasal bone(15.0%), Maxilla(11.0%) were next in order of frequency. 5. In 291 patients of Mandible fractures, 226(77.7%) had fractures only in Mandible and 65(22.3%) had another facial bone fractures. The most frequent fracture site of mandible was the Symphysis(43.0%) and Angle(22.4%), and Simple fracture was the most frequent in type of fracture(66.9%). Intermaxillarty fixatin & Open reduction was major method of treatment(36.9%). 6. In 394 patients of Midface fractures 323(82.0%) had fractures only in Midface and 71(18.0%) had another facial bone fractures. The most frequent site of Midface fractures was zygoma complex & zygomatic arch(42.7%), and Simple fracture was the most common type of fractures. Observation(Maxilla :44.2%, Zygoma :51.0%) and Open Reduction(Maxilla :20.0%. Zygoma :23.5%) were the major method of treatment. 7. The frequency of Nasal bone fracture was about 1/5 of Midface fractures, and Closed Reduction(42.2%) was the major method of treatment. 8. The complication was reported in only 16 patients, and Malunion was the major complication. 9. Head(44.4%), Lower extrimities(14.5%) and Eye(12.3%) were injured commonly with facial bone fractures. 10. The elapsed time from injury to hospital was within 24 hours in 73.8% of patients, however 15.5% of patients arrived the hospital 72 hours after injury.
