This study was conducted to investigate the effects of the properties of sugar (20％, 30%) and starch (l5％, 20%, 25％) to Angdo on Angdo Pyun's preference, texture and color_ Textural characteristics were examined through sensory evaluation, Rheometer. Color test by Color and color difference meter. The properties through sensory evaluation were appearance, color, flavor, hardness, thickness and acceptability. With Rheometer, compression force, work ratio, adhesive work and gumminess were measured. With Color and Color difference meter, L, a ana b were measured. The results were as follows: 1. Sensory evaluation indicated that with the increase of starch addition, the Angdo Pyun maintained a worse apperance and got hardened and thickened. As the amount of suger increased, the Angdo fyun maintained better in color and flavor as well as its acceptability. 2. Rheometer measurement indicated that a compression force, work ratio, adhesive work and gumminess tended to increase, as the starch proportion increased. As the amount of sugar increased, the Angdo Pyun maintained a greater adhesive work, work ratio and gumminess. 3. Color and Color difference meter indicated that figure L ana a tended to increase and b, ΔE and ΔC decrease, as the starch proportion increased. 4. In the analysis of correlation between hardness and compression force, it was found that they are highly related. In view of the above results, it came to the conclusion that Angdo Pyun with the addition of 30％ sugar and 15％ starch could give the best result among the groups studied.

Identification of salmonellosis-infected commercial poultry flocks has become a pivotal component of efforts to reduce incidence of egg-associated transmission of S. enteritidis and S. typhimurium to humans. As a basic study for sanitary control of S. enteritidis and S. typhimurium, main food-borne pathogenic bacteria in eggs produced by domestic hens, commercial egg samples were tested for specific antibodies to whole cells of S. enteritidis and S. typhimurium and outer membrane protein(OMP) of S. typhimurium by ELISA to detect infection of S. enteritidis and S. typhimurium in various groups of hens. When the antibody titers of yolks from three commercial brand eggs were tested after diluting in the ratio from 1:100 to 1:1,600 with double dilution method, ELISA values of the specific antibodies could be shown as differences in dilution patterns by comparing with negative control egg. When the antibody titers of the yolks from two commercial brand eggs were tested after diluting in the ratio of 1:200 and 1:1,000, ELISA values of specific antibodies were different among same brand eggs. When the antibody titers of yolks from five eggs sampled randomly from twenty one commercial brand eggs were tested after diluting in the ratio of 1:1,000, ELISA value of the specific antibodies were shown generally high. ELISA values of 28.5, 30, and 28.5% of yolks from 21 brand eggs were shown low and similar to negative control egg in antibody titers to whole cells of S. enteritidis and S. typhimurium and OMP of S. typhimurium, respectively. The results demonstrated that ELISA test of egg yolk antibody could provide a highly sensitive indicator to detect contamination of S. typhimurium and S. enteritidis in poultry, and could be used effectively to reduce incidence of S. typhimurium and S. enteritidis infection in poultry.

Background : Recognition and ingestion of opsonized microorganisms by neutrophils induces the burst of oxidative metabolic activity. Products of the respiratory burst activity provide powerful oxygen dependent killing mechanism. Measurement of respiratory burst activity has been a major indicator of the functional capacity of neutrophils. We determined the respiratory burst activity of neutrophils in patients with pneumonia and observed the changes during the clinical course of pneumonia. Methods: The EDTA blood was drawn from 24 normal controls and same numbers of pneumonia patients. The respiratory burst activity(with the production of $H_2O_2$ which changes nonfluorescent DCF-DA to green fluorescent DCF) in the non-stimulated state and the stimulated state with fMLP and PMA of neutrophils was measured by flowcytometry at day 1, 3, 5, 7 and 9 of admission. Results: The respiratory burst activity of neutrophils was mildly increased by stimulation with fMLP. But there was no statistical significance between normal control and patients with pneumonia. The respiratory burst activity of neutrophils was markedly increased by stimulation with PMA in both groups. There was a significant difference in response to PMA between normal control and patients with pneumonia. The production of hydrogen peroxide from neutrophils was decreased during early course of pneumonia and it was recuperated gradually to normal level in 9 days. Conclusion : Hydrogen peroxide production from neutrophils was suppressed during early course of pneumonia and restored after treatment. It is suggested that the production of oxygen radical in response to PMA stimulation from each neutrophils is decreased rather than increased during the early course of pneumonia.

Background : There have been several studies showing that the angiotensin II and angiotensin converting enzyme(ACE) contributes to the apoptosis of alveolar epithelial cells in idiopathic interstitial pneumonia and the activation of fibroblasts during the process of pulmonary fibrosis. These results suggest that the pulmonary fibrosis can be inhibited by the angiotensin II receptor antagonist(AGIIRA). This study was performed to identify the therapeutic effect of AGIIRA in idiopathic pulmonary fibrosis(IPF). Method : Thirteen patients with IPF, who were diagnosed with an open lung biopsy(6 patients) and furfilling the ATS criteria(7 patients) between March 1999 and October 2001 at the Gachon medical center, were enrolled in this study. Of these patients, eight patients were treated with a regimen including AGIIRA(AT group), and five were treated without AGIIRA(NT group). The pulmonary function tests and dyspnea(ATS scale) were measured at diagnosis and 1 year after treatment. All the data was collected to analyze the therapeutic effect of AGIIRA on the patients with IPF. Results : The AT group contained 8 patients(M:F=4:4) and the NT group contained 5 patients(M:F=3:2). There was no significant difference in the serum angiotensin II level between the two groups($202.5{\pm}58.5$ vs $163.7{\pm}47.3pg/ml$, p>0.05). The AT group showed an upward trend in TLC(+3%), FVC(+4%), FEV1(+3%) and DLco(+2%) compared to the NT group(TLC(-14%), FVC(-3%), FEV1(-4%) except for DLco(+5%)). The dyspnea score in the AT group improved significantly but not in the NT group. Conclusion : These results suggest that the angiotensin II receptor antagonist may have an effect on stabilizing IPF.

In order to explore microleakage in class V cavity based on different kinds of several dentin adhesive and composite resin, 2 kinds of composite resin was restored and exposed after applying 4 kinds of dentin adhesives. Deposited in methylene blue solution for 4 hours and cut in parallel with tooth longitudinal axis. By observing dye penetration level of enamel and dentin margins of each restored resin following conclusion was obtained. 1. In composite resin Filtek Z350XT Universal (3M/ESPE Dental Products, USA) in enamel margin, Easy Bond (3M/ESPE Dental Products) showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2 (3M/ESPE Dental Products), Scotchbond Multi-Purpose (3M/ESPE Dental Products) and Cearfil SE Bond (Kuraray Medical Inc., Japan). In case of Filtek Z350XT Flowable (3M/ESPE Dental Products), Scotchbond Multi-Purpose showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2, Clearfil SE Bond and Easy Bond. 2. In case of Filtek Z350XT Universal in dentin margin, Easy Bond showed the lowest microleakage and this leakage was represented to be high in the order of Scotchbond Multi-Purpose, Single Bond 2 and Clearfil SE Bond. In case of Filtek Z350XT Flowable, Scotchbond Multi-Purpose and Single Bond showed the lowest microleakage and this leakage was represented to be high in the order of Clearfil SE Bond and Easy Bond. 3. In all the groups excepting S-U group (Single Bond 2+Filtek Z350XT Universal), enamel margin showed more higher microleakage than that of dentin margin. 4. There was a difference between enamel and dentin margin among each group but it was not significant statistically (p>0.05). When summarizing this result, it is considered that composite resin and dentin adhesive could be applied selectively and particularly in case of applying 1-step self-etching dentin adhesive, this method would be advantageous for manipulation convenience and shortening of operation time.

The purpose of this study was to investigate the effects of the regular Upright Body Type Excercise on posture, muscle strength of leg, lung capacity and depression of people with mental illness. The subjects of this study were recruited from B mental health center (5 years and more mental illness patients, n=19) located in P city. For the exercise group, They were carried out the Upright Body Type Excercise Program during 8 weeks (60 min/time, 3 times/week). They were randomly divided into two groups. Exercise group (n=10) and Control group (n=9). And also, they were agreed with consent forms before the experiments. Research results were as follows. Through the upper body type exercise, there was significantly difference in PEF and FEV1/FVC in the trained group. And also, there was much improved in depression level in the trained group. The change of melancholy feeling before and after the program was not statistically significant. However, because of limitations of sampling size due to the peculiarities of the program participants, in consideration of the limit of statistical validation exists clearly, intended to better understand the subjective experience of attendees, qualitative analyzing(qualitative research) was carried out in parallel. It was conducted a deep interview only person accepted among program participants, thematic analysis, subject analysis tasks to be subdivided by classifying by considering the semantic units of what participants expressed, was thus carried out. It found that the degree of melancholy feeling of mental disorders who participated in the Upright Body Typed Exercise Program was reduced. The course of the experience of change in depression appered the three subjects and six sub-themes such as "the start of the change", "interest of the program", "recognition of the need of the body’s health", "physical health promotion", "recovery of physical function", "negative change of habits (attitude)", "reduction of sense of depression", "confidence that it is possible to", "hope for the future". Therefore, upper body type exercise is much helpful in lung capacity and mental health of people with mental illness. So, this type of exercise mostly needed in the people with mental illness group than the other group for the quality of life.

1) The authors studied the effect of increasing age on the contraction and relaxation mechanism in the ureteral smooth muscle of the guinea pig. 2) Two to three week old, three month old, and two to three year old guinea pig ureters were used and the consistent amplitude of contratile responses were induced by using train stimulation. 3) After mounting the specimens in Tyrode's solution containing 2.6mM $Ca^{++}$, the ureter was stimulated, of which amplitude was initial contraction and next continuously superfused with $Ca^{++}$-free Tyrod's solution. When the contractile response stopped by electrical field stimulation, the muscle specimens was superfused with Tyrode's solution 0.25mM $Ca^{++}$ for 15min and stimulated with the same parameters. Thereafter, the contraction of $Ca^{++}$ in the solution was increased step by step up to 2.7mM. 4) The ureters of 2-3 week old guinea pigs needed less $Ca^{++}$ for the recovery of contractile response than those of three month and two to three year old did. In 2.7mM $Ca^{++}$, the ureters of 2-3 week and 3 month old guinea pigs recovered the contractile response of over 90% but those of 2-3 year old recovered the contractility of 77.2%. 5) Isoproterenol inhibited in dose dependent manner from $10^{-7}$ to $10^{-5}\;M$ ureteral contractility of both 2-3 week and 2-3 year old guinea pigs. The inhibition of the old ureter by isoproterenol was significantly less (P<0.025) than that of the younger ureter. However theophylline showed the strong inhibition independent of the function of age. 6) Dibutyryl cyclic AMP showed dose-dependent inhibition of the contraction of ureters of 2-3 week old guinea pigs but there was shown no inhibition in the old ureters. Further, the content of endogenous cyclic AMP in the two week old ureter was higher by 73% than that of 17 month old ureter. Cyclic GMP contents was not much different between two groups. 7) The ureteral smooth muscle of the younger guinea pig had more efficiency than that of the older animals in the mobilization and storage of calcium which concerned itself in the contraction and relaxation mechanism.

Twenty seven species of pufferfishes (family Tetraoaontidae) have been examined to find their generic characters based on vertebrae and pterygiophore characters of specimens collected in 20 localities along the coast of Korea from March, 1991 to March, 1994. It was divided by 3 groups based on vertebrae number as follow : the genera Lagocephalus, Pleurancanthus, Spheoides, Arothron, Chelonoeon and Canthigaster have 17$\~$19 vertebrae, genera Ephippion, Boesemanichthys and Feroxodon have 20 vertebrae, and genus Takifugu have 19$\~$25 vertebrae, The number of vertebrae ranged from 17 to 25 with the maximum of 25 in Takifugu obscurus. The modal number of vertebrae in Lagocephalus is 17 (L. lunaris), 18 (L. inermis), and 19 (L. gloveri, L. wheeleri, L. larigatus), with the lower number more specialized. Paired neural spines appear at number of the 1st$\~$5th vertebrae in Takifugu pardalis, Takifugu obscurus and at number of the 1 st$\~$4 th vertebrae in the other species and genera. All of the species of Lagocephalus and Pleurancanthus have dorsal and ventral pterygiophores processes, and flat-shaped epural, while none of the abdominal vertebrae processes complete haemal arches. The neural and haemal spines of the last few caudal vertebrae aye shorter in Pleurancanthus than in the other genera, associated with the depressed caudal peduncle. The genus Canthigaster is distinguished the first pterygiophores of the dorsal and ventral fins is always much larger than the others genera. Based on the haemal arches and spines of the abdominal vertebrae, genus Canthigaster has different characters from the other genera of the family Tetraodontidae.

The purpose of this study was to analyze health-related habits, weight control experience and body composition of 344 female students visiting nutrition counselling office. Dietary habits of the subjects were assessed by means of interview with questionnaire and nutrient intakes were evaluated by the simple dietary assessment method. Weight and height were measured to get body mass index(BMI) and waist-hip ratio and their body composition were measured by Inbody 3.0. The obtained results were as follows: 1) Among students, 14.5% were exercising on a regularly basis, of which the exercises were walking and gymnastic exercise(22.1%), jogging(14.1%), and rope-skipping(4.7%), 48.4% of students were little drinking and 30.5% were once a week and smokers were 4.1%. 2) 28.3% of students were little having breakfast and 15.1% were once or twice a week. Two third of total students were not having breakfast regularly. Also only 59.6% of students were having dinner everyday, which means many of them were even skipping dinner. The reasons why they were not having breakfast were because they don't have enough time to eat(66.0%) and for a diet(2.8%) and the reasons for skipping dinner were because they were not hungry(23.0%), for the weight loss(18.2%). It was shown that they would skip dinner rather than breakfast for a weight control. 51.6% of students were taking snack 1~2 times a day and 5.3% were having little snack. 55.4% of students were dining out once a day and 15.4% more am 2 times a day. 3) 46.7% of students were already experiencing weight control before visiting the counselling office. 78.5% of students tried on one kind of weight control method, 11.4% on two kinds, and 10.1 % on more than three kinds. The method they tried for a weight control most was the one food diet using egg, fruits and beans, which is the most popular among them, and the next were an aerobic exercise(23.6%). a diet tried by a famous entertainer (15.5%), and the fasting(14.5%). 4) The average BMI was 21.2 and the body fat rate was 28.1%. As a result of grouping BMI, 12.8% were underweight 67.6% normal weight 11.6% overweight and 8% obesity. Less than standard for the body fat rate were 0.6%, 50.6% standard, 48.5% more than standard. 49.2% of students as normal weight on a BMI were assessed the so-called "skinny obesity. 50% of consulted students situated fat intra-abdominally at the umbilical level(WHR>0.8). 5) The energy intake was 76.6$\pm$17.8% of RDA and constituent ratio of carbohydrate, fat and protein were 64.2$\pm$5.2%, 21.6$\pm$3.7% and 14.3$\pm$2.3%, respectively, which is little over of 20% of recommended ratio of fat. Protein and niacin intake were more than 90% of RDA and riboflavin and vit. C were taken more than 100% of RDA. But Fe intake was 69.4$\pm$19.3%, Ca 76.6$\pm$23.6%, which were the least constituents. There was not remarkable significance between energy intake and nutrient density based on the groups of underweight, normal weight, overweight and obesity of BMI. 6) It was shown that body fat rate had remarkably significant correlation(p<0.000) with BMI(r=0.760) and WHR(r=0.817) respectively, but body fat rate was more correlated with WHR than with BMI. There was not much significant difference between body fat rate and WHR whether they exercised or not. However. BMI was significantly higher in the exercise group because one who showed higher BMI started to exercise since they looked fat in appearance and perceived as they were fat. fat.

This study has been done in order to analyze the relationship between climacteric symptoms and the stress of life events. For the purpose of this study. objectives set up were as followings. : 1. Climacteric symptoms complained by middle aged women are studied. 2. The stress of life events experienced by middle aged women is studied. 3. The relationship between climacteric symptoms and the stress of life events is studied. 4. The relationship between climacteric symptoms and general characteristics is studied. and the relationship between the stress of life events and general characteristics is also studied. The sample size of this study was 462 cases. The subjects were middle-aged women. who were from 40 to 60 years old and resided in Seoul. Data were collected by using questionnaires which consisted of 122 questions from Jan. 1 to Feb. 7 in 1992. The questionnaires include questions about general characteristics. climacteric symptoms and life events. The measurement scales for this study were adopted from the climacteric symptoms scale developed by Chi. Sung-Ai and the measurement scale of stress related to life events devised by Lee. Pyoung Sook. The analysis of data collected was done by using SPSS-pc package. Firstly. general characteristics were analyzed by using descriptive statistical methods. Secondly. climacteric symptoms were analyzed by using descriptive statistical methods. the analysis of variance and correlation analysis. Thirdly. the stress of life events was studied by using descriptive statistical methods. the analysis of variance. and tests of independence. The results of this study are as followings. 1. General characteristics of the respondents are as followings: The average age is 49. 13. and the age group from 46 to 50 has $30.5\%$ in the respondents. Christianity is the major religion $(42.6\%)$. and the respondents with a high school diploma are $(43.1\%)$ of the respondents. $60\%$ of all respondents are housewives. and $90.5\%$ are married. The average number of children is 2.71. and the average number of family is 4.24 Monthly income of $39.1\%$ of the respondents is from l,010,000 Won to 2,000,000 Won. The premenopausal group is $4.9\%$. and $45.5\%$ of all respondents are satisfied with marrital life. $43.3\%$ of all feel happy. and $13.9\%$ feel economic frustration. $27.9\%$ of respondents are satisfied with sexual life. and $45\%$ of all report that the amount of recreational activities are more needed. 2. The average score of climacteric symptoms is 1. 8461 (The maximum score is 5.0). The symptoms complained frequently are nervousness. muscle-ache. fatigue. headache and knee-ache. Climacteric symptoms are significantly different in menopausal states. age groups. the number of children, marrital satisfaction. the feeling of life. self-reported health states and sexual satisfaction. 3. The life events occurred frequently were 'discord with husband', 'children's important exams', 'separation from husband related to works' and 'vacation'. When life events are analyzed by factors. the most frequently mentioned factor is 'marrital life'. The stress of life events is significantly different in a few general characteristics (age. the number of children, the number of family, monthly income, menopausal status, the feeling of life. self-reported health states, economic satisfaction). 4. The score of climacteric symptoms complained is significantly different according to the stress of life events (p<0.051, Especially, the difference is the widest in psychological symptoms according to the factor of 'couple. marrital life' among stressful life events. In Summary, climacteric symptoms complained by middle-aged women are related to the amount of the stress of life events. Whether life events are positive of negative is not important. Yet. climacteric symptoms and stressful life events are deeply related to general characteristics. so we can not insist strongly that one be directly related to the other.
