  • The growth process of the Chungkook-jang that occured by utilizing such traditional methods as Bacillus natto and Bacillus subtilis method has been examined. The results of the experiment in which the changing process of elements during the storage period had been measured are as follows: 1. During the growth period, concerning any change in pH, the storage period had been declined and after 18 days pH rose above 7.0. Salt content was between $5.28{\sim}6.40%$ and Bacillus subtilis fungus showed the highest titrable acidity. 2. Moisture content was between $50.94{\sim}56.74%$ and crude protein content range was $14.44{\sim}18.60%$ indicating irregularity in pattern resulting from the testing equipment groups, whereas crude fat and crude fiber tend to decrease in general. 3. During the storage, total sugar and ethyl alcohol content in all of groups tended to decrease and after 18 days Bacillus subtilis total sugar content was the lowest. 4. Amino nitrogen and water soluble nitrogen content increased with days, but no difference was found between groups. 5. Amylase and protease activity showed irregular pattern with time, but no significant difference between groups was found.

  • The patterns of fungal growth and fiber digestion under the microscope, and tile productions of fibrolytic enzyme were studied in an in vitro culture with Neocallimastix frontalis SA when either filter paper or rice straw was provided as sole energy source. Under the microscopic observation, active zoospores attachment, sporangium development and complex rhizoidal system were founded on the surface and at the edge of filter paper. After 7 days of incubation, a reduced fiber mass, a decreased fiber cohesion and a weakened fiber structure by fungal digestion were clearly observed. Similar fungal development was observed with rice straw, but fungal growth and digestion took place mostly on the damaged and exposed portion of rice straw. Although there were some differences in absolute concentration and pattern, the concentration of both cellulase and xylanase increased with incubation time with the higher activity being obtained with filter paper. Their differences were large especially after 48 and 96hr of incubation(P< 0.05). The filter paper was more good inducer of cellulolytic and xylanolytic enzymes compared with complex substrate, rice straw. These findings suggest that the filter paper is the better energy source for N frontalis than the complex substrate, and structural disintegration by physical process is able to help rumen fungal growth on the lignified roughage although anaerobic rumen fungi have mechanical and enzymatic functions for fiber digestion.

  • This study was conducted to investigate the physiological properties of various parts of skate body after fermentation by measuring compositional properties including pH and $NH_4^+$. Other functional properties, such as antibacterial activities, antioxidative activities and anticancer activities were measured. Effects of fermentation temperature (4, 10, $20^{\circ}C$) did not affect compositional properties of fermented skate. The pH of fermented skate extract at 4$^{\circ}C$ did not increase as much as that at 10 and $20^{\circ}C$, Particularly at $10^{\circ}C$, the pH increased rapidly after Day 1 and remained unchanged until another increase at Day 5. At 2$0^{\circ}C$, the pH increased rather rapidly at early stage of fermentation and reached 8.9 at Day 4. The pattern of $NH_4^+$ concentration of fermented skate extract was similar to that of pH. Particularly at $4^{\circ}C$ fermentation, $NH_4^+$ concentration was not affected by fermentation time. The concentration of $NH_4^+$. reached approximately $10.2\mug/mL$at $10^{\circ}C$ for Day 5 and $20^{\circ}C$ for Day 4-5, indicating the early stage of fermentation. According to physiological activities of hot water extracts of skate fillet and viscera as affected by fermentation time, antibacterial activity of 2% viscera extract concentration was 43.3% at Day 8, while there was no antibacterial activity from fillet extract. As for the antioxidative activity, fillet extract and viscera extract both at 2% concentration at Day 0 showed 61.2% and 54.4%, respectively. Anticancer activities were highest (52.7% for fillet extract and 58.3% for viscera extract) at $1,000 \mug/mL$ concentration at Day 8. Antibacterial activities and anticancer effects were relatively high as fermentation was progressed, while antioxidative activities were highest before fermentation started. As for the physiological activities of hot water extract from brain and cartilage, antibacterial activities were observed at 41.0% when 2% brain extract was added at 4 hours of incubation, while 35.8% with 2% cartilage extract at 14 hours of incubation. Antioxidative activities were not found in brain extract, but cartilage extract at 2% showed 25.0% of antioxidative activity, which was lower than fillet and viscera extract.

  • This study was conducted to determine chemical compounds and antioxidant in Aruncus dioicus. Further, effects of cultural practices such as the shading conditions on the general compounds, essential oils and antioxidants. The chemical compounds and antioxidant activity of edible extracts on the shading cultivation and harvesting time were measured by crude fiber, pigments, higher fatty acids, essential oils and DPPH free radical scavenging ability and activities of SOD and POD in edible shooting parts of Aruncus dioicus. The contents of crude fiber, total chlorophyll and total carotenoids in extracts of edible shooting by shading cultivation and later harvesting were higher than those of non-shading cultivation and early harvesting. Phenolic compounds such as benzoic acid were identified as the aromatic compounds in the edible extracts of Aruncus dioicus. The contents of azulene, benzaldehyde and linalool among those compounds on the cultivation conditions increased in shading cultivation. $IC_{50}$ values of DPPH free radical scavenging activities were high from 6.644 to $14.499{mu}g/m{\ell}$ in extracts of edible parts and those of edible shooting parts was high such as edible shooting cultivated by 60% shading, 30% shading and non-shading, respectively. The activity of POD and SOD in seeds was lower than that of edible shooting and that by shading cultivation was high in extracts cultivated by non-shading. POD activity of extracts on harvesting time was high in earlier harvesting but SOD activity was low. The numbers of isozyme pattern of POD and SOD in seedling showed 7 bands and 3 bands, respectively, especially, bands of POD and SOD in the first year-growing plant did not show and show a difference according to plant positions, respectively.

  • The study was carried out at W. hospital, an affiliated hospital of Y university, involved a total of 163 patients who were discharged from the hospital between May 1990 und March 199J. Data collection was twice, just prior to discharge and a minimum of three months post discharge. Thirty patients who lived within a hour travel time of the hospital received home care during the three months post discharge. Nursing diagnoses and nursing interventions For these patients were analyzed in this study. The results of the study are summarized as follows : 1. Discharge needs for the subjects of the study were analyzed using Gordon's eleven Functional categories and it was found that 48.3% of the total sample had identified nursing needs. Of these, the needs most frequently identified were in the categories of sexuality, 79.3 %, health perception, 68.2 % self concept, 62.5 %, and sleep and rest 62.5 %. Looking ut j he nursing diagnosis that were made for the 30 patients receiving home care, the following diagnoses were the most frequently given; alteration in sexual pattern 79.3%, alterations in health maintenance, 72.6%, alteration in comfort, 68.0%, depression, 64.0%, noncompliance with diet therapy, 6.3.7%, alteration in self concept, 55.6%, and alteration in sleep pattern, 53%. 2. In looking at the effects of home nursing care as demonstrated by changes in the functional categories over the three month period, it was Found that of the 11 functional categories, the need level for health perception, nutrition, activity and self concept decreased slightly over the three month period. On the average sleep patterns improved, but restfulness was slightly less and bowel elimination patterns improved but satisfaction with urinary elimination was slightly less. On the other hand, role enactment, sexuality, stress management and spirituality decreased slightly. The only results that were statistically significant at the 0.05 level were improvement. in digestion and decrease in pain. No statistically significant changes were found in ability related to ADL, the total ADL Score at discharge was $19.78{\pm}8.234, and after 3 months $19.01{\pm}8.12$. Considering that a majority of the patients were over 60 years of age and that many had brain or spinal cord injuries, the fact that their ADL ability did nor deteriorate after discharge can be interpreted as related to a positive impact by the home health care nurses. Similarly there was a slight be not statistically significant decrease in the quality of life scores between the two lest times(l47.83 at discharge and 113.02 at the three month period). Again, when the chronic nature of thee problems facing these patients is considered this maintenance of quality of life can be interpreted as a positive impact by the home health care nurses. 3. One of the home care nursing activities was diagnosis. For this activity it was found that for nine functional health categories(sexuality and spirituality excepted) there were 20 nursing diagnoses. The most frequent were noncompliance, alteration in skin integrity both actual and potential, and impaired physical mobility in that order. 4. Delivery of home health care by the home health nurses included the following nursing activities; assessment, patient education, demonstration of care activities, counselling, direct care to the patient and referrals. Direct care included changing dressings, bladder irrigations, changing Foley catheters, measurement of residual urine, perineal care, position change, back care, oral hygiene, exercise and massage of motion exercises, cleansing enemas, tracheostomy suctioning and tracheostomy care, care of dentures, applications of heat and other similar nursing activities. In conclusion almost 50% of (he sample indicated a need for continued nursing care at the time of discharge and for the patients in the sample who received home care there was a slight decrease in nursing needs but while the patients had chronic and debilitation problems there was ill decrease in ADL abilities or in quality of life. Further study needs Lo be done La increase the reliability and validity of the tool that was used to measure home health care needs. It is also recommended that study by done using a randomized sampling with a control group to compare patients who receive home care with those who do not.

  • We have found an error in the operational OMI HCHO columns, and corrected it by applying a background parameterization derived on a 4th order polynomial fit to the time series of monthly average OMI HCHO data. The corrected OMI HCHO agrees with this understanding as well as with the other sensors measurements and has no unrealistic trends. A new scientific approach, statistical analyses with EOF and SVD, was adapted to reanalyze the consistency of the corrected OMI HCHO with other satellite measurements of HCHO, CO, $NO_2$, and fire counts over Africa. The EOF and SVD analyses with MOPITT CO, OMI $NO_2$, SCIAMAHCY, and OMI HCHO show the overall spatial and temporal pattern consistent with those of biomass burning over these regions. However, some discrepancies were observed from OMI HCHO over northern equatorial Africa during the northern biomass burning seasons: The maximum HCHO was found further downwind from where maximum fire counts occur and the minimum was found in January when biomass burning is strongest. The statistical analysis revealed that the influence of biogenic activity on HCHO wasn't strong enough to cause the discrepancies, but it is caused by the error in OMI HCHO from using the wrong Air Mass Factor (AMF) associated with biomass burning aerosol. If the error is properly taken into consideration, the biomass burning is the strongest source of HCHO seasonality over the regions. This study suggested that the statistical tools are a very efficient method for evaluating satellite data.

  • Objective: The Yip1 domain family (YIPF) proteins were proposed to function in endoplasmic reticulum (ER) to Golgi transport and maintenance of the morphology of the Golgi, which were homologues of yeast Yip1p and Yif1p. YIPF3, the member 3 of YIPF family was a homolog of Yif1p. The aim of present study was to investigate the expression and regulation mechanism of porcine YIPF3. Methods: Quantitative realtime polymerase chain reaction (qPCR) was used to analyze porcine YIPF3 mRNA expression pattern in different tissues and pig kidney epithelial (PK15) cells stimulated by polyinosine-polycytidylic acid (poly [I:C]). Site-directed mutations combined with dual luciferase reporter assays and electrophoretic mobility shift assay (EMSA) were employed to reveal transcription regulation mechanism of porcine YIPF3. Results: Results showed that the mRNA of porcine YIPF3 (pYIPF3) was widely expressed with the highest levels in lymph and lung followed by spleen and liver, while weak in heart and skeletal muscle. Subcellular localization results indicated that it expressed in Golgi apparatus and plasma membranes. Upon stimulation with poly (I:C), the level of this gene was dramatically up-regulated in a time- and concentration-dependent manner. pYIPF3 core promoter region harbored three cis-acting elements which were bound by ETS proto-oncogene 2 (ETS2), zinc finger and BTB domain containing 4 (ZBTB4), and zinc finger and BTB domain containing 14 (ZBTB14), respectively. In which, ETS2 and ZBTB4 both promoted pYIPF3 transcription activity while ZBTB14 inhibited it, and these three transcription factors all played important regulation roles in tumorigenesis and apoptosis. Conclusion: The pYIPF3 mRNA expression was regulated by ETS2, ZBTB4, and ZBTB14, and its higher expression in immune organs might contribute to enhancing ER to Golgi transport of proteins, thus adapting to the immune response.

  • Beat-to-beat changes in heart period (heart period variability, HPV) are mediated by fluctuations in autonomic activity. Spectral analysis is used to quantify such fluctuations in the range of 0.15-0.40 Hz (high frequency, HF), which are influenced primarily by parasympathetic factors. These fluctuations are often referred to as RSA (respiratory sinus arrhythmia), the physiological phenomenon extracted by spectral analysis and other methods including histograms of heart rate ( HR), deviations of HR etc. Respiratory sinus arrhythmia indexing with peak-to-valley method suggested by Grossman et at., (1981) yields a simple range statistic and is quantified on breath-by-breath basis, thus being quite sensitive and less dependent on recording time as compared to spectral analysis. It is strongly recommended to use at least 1 min epoch to asses HF component of HPV and at least 2 min fer low frequency (LF) of HPV and even 5 min far valid clinical assessment. Peak-to-valley statistic is limited to RSA index only, but has its pragmatic advantages. Most important is possibility of its application far relatively small epoch analysis. We used short periods (20,30, 40 sec only) and off-line analysis of RSA using ECG and respiration curve this method of assessment and proved that this method is more practically effective. The RSA index was not so far dependent on respiration pattern differences and reflected actual vagal control of HR and were accompanied by low HR under some high stress conditions and in an aversive affective visual stimulation experiments. Another factor that might modulate cardiac chronotropic response is the interaction of sympathetic and parasympathetic inputs on sino-atrial (SA) node level, because responses to vagal influences are known to be proportional to ongoing sympathetic activity, that is so called accentuated antagonism. Since sympathetic outflow (increment of influences on SA) under negative emotions or stress was high in almost all physiological responses, vagal effects on HR could be therefore potentiated, leading to masking of output cardiac response seen in HPV, In the case of moderate sympathetic activation, on the other hand, autonomic interactions in cardiac control appear to be minimal. Thus RSA index appears to be an effective alternative method to assess and measure spectral HPV.

  • It has been reported from our department that a few agents, such as $K_2S_2O_5,\;NaHSO_3,$ nicotinamide have a marked stabilizing effect in vitro on metoclopramide which is relatively unstable compound. In order to study the effect of these stabilizers on the action of metoclopramide in vitro, the fate of this compound combined with $K_2S_2O_5,\;NaHSO_3$ and nicotinamide, respectively, was studied and furthermore, the change of the biological activity of metoclopramide due to these stabilizers was studied by using the isolated stomach strip of rat. The blood concentration of metoclopramide was measured by using Bakke's method at the various time after intravenous injection of the mixed metoclopramide solution with the stabilizers. In order to study the excretion of the drug, rabbits were anesthesized and catheterized into bladder for withdrawal of urine. After intravenous injection of the mixed metoclopramide solution, urine was collected for 5 hours and the conjugated forms of metoclopramide as well as the free form were determined by using Arita's method. In the biological study of the metoclopramide combined with stabilizers, the contractability of the isolated rat stomach strip was observed by using polygraph recorder. The results were following: 1. When metoclopramide was administered with nicotinamide as stabilizer, the blood concentration of the unchanged from and the rate of the clearance of this compound were very similar to that of metoclopramide alone. On the other hand, other stabilizers, $K_2S_2O_5\;and\;NaHSO_3$, brought about 40% decrease in blood concentration of the unchanged form at 15 min after intravenous injection however, the rate of clearance of metoclopramide with $K_2S_2O_5\;or\;NaHSO_3$ was very slow. 2. In the case of urinary excretion, the excretory pattern of the metabolites of metoclopramide with $NaHSO_3$ or nicotinamide was very similar to that of metoclopramide alone. But metodopramide plus $K_2S_2O_5$ group showed the maked depression of excretion for first 1 hour. 3. In composition of metabolites, when metoclopramide was administered with $K_2S_2O_5$ or $NaHSO_3$, the sulfonate conjugation was predominant. But the glucuronic acid conjugation was predominant in metoclopramide plus nicotinamide gronp. 4. In the experiments on the biological activity of the metoclopramide, this compound exhibited the marked contracting effect in isolatd rat stomach strip. Specially, the meetoclopramide combined with $K_2S_2O_5$ showed the strong contraction of the isolated strip, suggesting the potenciating effect of $K_2S_2O_5$ on the action of metoclopramide in the isolated strip.

  • This study aims to discover patterns of Korean women's life course in terms of their life time sequence of family roles and economic activity. Primary factors for the change and diversity of family-work role sequence are also examined. Data used in this study is the Fourth Survey of Korean Women's Economic Activity which was conducted by Korean Institute of Women Development (KIWD) in 2002. According to the main results, five distinctive patterns of life course are to be disentangled for ever married women: First, doing simultaneously family and work roles with no maternal leave (13.7%); second, reentry into labor market after maternal leave (M type, 18.6%); third, no reentry into labor market after maternal leave (latent M type, 26.9%); fourth, first job entry after child rearing (23.5%); and finally, no work experience (17.3%). The relative composition of the respective life course has changed over marriage cohorts. M type including latent M type became a dominant life pattern among married women since marriage cohorts of 1980 and later. The share of married women who begin to work first after maternal role or have no work experience has declined with recent marriage cohorts. It is also noted that the share of women with simultaneous family and work roles has increased among marital cohorts of 1990 and later. Marriage cohort differences being controlled, life patterns significantly differ by women's educational level, existence of role model of working mother at growth, women's own and husbands' gender role attitude, and family economy. Finally, some policy concerns for gender role division of family and work are raised.
