The purpose of the study was to improve the efficiency of Breath & Forced Vital Capacity(FVC) of Stroke Patients Using Record Playing Focused on Breath Training. The Training of Forced Vital Capacity(FVC) is focused on trunk muscles reinforce for Breathing. So the study tried to play Recorder for reinforcing FVC. The play included the two parts. One was for solo play, the other was play in concert base on solo play using Korea country song, Arirang. The Recorder play used abdominal breath, Pursed-lip & Paced methods. The course of play included Long Tone, Staccato, Crescendo, Decrescendo and throughout the course we tried to improve the efficiency & Quantity of breathe. Experiment performed at Social welfare institute for the old. They played & checked FVC, $FEV_1$, $FEV_1/FVC$ before & after breathe 19 times for 6 weeks using Spirovit SP-1, Schiller. After experiment we performed statical process(p<0.05) using statical Package software. The findings were as follows: Analysis for Experiment showed the numerical Value of increasing Of FVC, $FEV_1$, $FEV_1/FVC$. Increasing Percentage of Measured/Predicted FVC, $FEV_1$ (or calculated based on theory) ration was 25%, 13% and Quantity of FVC, $FEV_1$ 35%, 40%. Also $FEV_1/FVC$ Ratio(showed efficiency of breathe) raised 13%. And experiment data was confirmed by statical process. The experiment data was valuable under p<0.05. In Conclusion we think the results of experiment showed the efficiency of Music therapy for Breathe(FVC, $FEV_1$, $FEV_1/FVC$) reinforce.

This study was designed to determine the level of soybean meal (SM) that could be substituted for fish meal in the diet for Korean rockfish (Sebastes schlegeli). A control diet with white fish meal as only protein source was included, SM was substituted at levels of $5\%,\;10\%,\;15\%,\;and\;20\%$ for portions of the fish meal in the diet. Amino acids (met+lys) supplementation and two different SM particle sizes (0.5 mm and 0.25 mm) in the $20\%$ SM diet were compared. In addition, combination of $10\%$ SM, $10\%$ corn gluten meal (CGM) and $10\%$ meat and bone meal (MBM) was substituted for the fish meal in the diet. Duplicate groups of the 30 fish averaging 22.9 g were fed one of 8 isoproteic $(48\%)$and isolipidic $(7.5\%)$ experimental diets to satiation twice a day for 9 weeks. No significant differences were found among fish fed the control, substituting up to $20\%\;SM,\;20\%$ SM containing amino acids, and $10\%\;SM+10\%\;CGM+10\%$ MBM diets in weight gain, feed efficiency, daily feed intake, and protein retention (P>0.05). Feed efficiency, daily feed intake and protein retention in fish fed the diet containing $20\%$ SM with 0.5 mm particle size were not significantly different to those in fish fed the diets containing less than $20\%\;SM\;(P>0.05)$, however, weight gain was significantly lower than that of the control and $5\%\;SM\;diets\;(P<0.05)$. It is concluded that SM ran be used as a partial substitute for fish meal up to $20\%$ in the diet, and that the inclusion of SM with an adequate combination of several protein sources can replace larger amounts of fish meal in the diet.

Purpose: The purpose of this study is to investigate the effect of age in the response to long-term overnight orthokeratology (OK) lens wearing. Methods: Among volunteers, ninety-five healthy subjects who had no eye diseases and could wear OK contact lens at least for 8 hours every day were divided into three groups children, youngsters and young adults. Unaided logMAR visual acuity, refractive error, apical corneal radius, corneal asphericity and central corneal thickness were measured with different period; before and after one day, one week, two weeks, one month, three months and six months of OK lens wear. Paired student t-test, ANOVA analysis and Pearson correlation were used with a critical p value of 0.05 for statistical analysis. Results: All groups showed statistically significant (p<0.001) improvement in unaided visual acuity, a trend for flattening in the apical corneal radius, decrease in central corneal thickness and less prolate after OK lens wear. The child group showed significantly rapid change (p<0.001) in visual acuity, and apical corneal radius showed that they reached the targeted refractive change earlier compared with youngster and adult groups. The visual effect of OK lens was significantly related with the change in central corneal thickness after long-term OK lens wear, especially in child and youngster group, and central corneal thickness were highly correlated with the targeted refractive change. Conclusions: Visual acuity change is statistically correlated with the central corneal thickness change, which is highly correlated with targeted refractive change in the long-term orthokeratology and younger lens wearers showed a rapid response to OK lens wear, suggesting a reduced epithelial response with increasing age. The results found this study extends our understanding and development in the long-term orthokeratology.

Purpose : Among perinatal risk factors, neonatal seizures are one of the strongest independent discriminators of adverse outcome, representing high risks of mortality and neurologic morbidity. This study was undertaken to evaluate the neurologic outcome of neonatal status epilepticus according to underlying etiology, seizure pattern, onset time, and duration. Methods : We reviewed retrospectively 36 neonates(19 males, 17 females) with status epilepticus who were admitted to the neonatal intensive care unit, Inha Hospital between July, 1988 and June, 2003. They were evaluated with neurologic examination, laboratory data, EEG findings, and neuroimaging studies etc. Results : The mean gestational period of the patients was $37.0{\pm}3.6$ weeks and birth weight was $2.70{\pm}0.82$ kilogram. Fifty two point eight percent of the neonates were male and 66.7 percent were born at term. The most common cause of neonatal status epilepticus was hypoxic-ischemic encephalopathy. In preterm babies, intracranial hemorrhages showed an especially high frequency(P=0.034). Gestational age and birth weight did not show a correlation with neurologic complications. The incidence of neurological sequelae were significantly related to prolonged seizures lasting more than 1 hour(P=0.002). Neonates with seizures within the first 72 hours tended to be more frequent among those who developed adverse outcomes(P=0.016). Generalized tonic seizures had the worst prognosis, whereas those children who had subtle seizures had better outcomes than any other type(P<0.05). Generalized tonic seizures were primarily represented on EEG by abnormal background, whereas subtle seizure showed a significantly more normal EEG than any other seizures(P<0.05). Conclusion : Our results indicate that neonatal status epilepticus with early onsets, prolonged durations. And generalized tonic types can predict an increased risk for neurologic sequelae. So, those seizures must be perceived as medical emergencies and treated aggressively with antiepileptic drugs.

Purpose : Cholestasis is a major complication in prolonged use of TPN, especially in the neonatal period, but there are few long-term reviews examining the clinical course in premature infants. Thus, in this study, we reviewed premature infants with TPN-associated cholestasis(TPNAC) to determine the incidence, clinical courses and possible risk factors. Methods : Retrospective review of 66 premature infants less than 2,000 gm of birth weight and on TPN for more than two weeks was performed. Cholestasis was defined as a serum direct bilirubin level greater than 2.0 mg/dL. The clinical course of cholestasis was described, and perinatal risk factors were evaluated. Results : TPNAC developed in 21 out of 66 infants(31.8%). The onset was $41.7{\pm}17.4days$ after receiving TPN, and the mean duration was $33.6{\pm}23.4days$. The incidence of TPNAC was significantly correlated with birth weight, and gestational age, and duration of TPN. But, possible etiologic factors, such as incidence of perinatal asphyxia or infection, showed no remarkable differences between infants with TPNAC and those without TPNAC(control). The enteral intake in the third postnatal week was significantly smaller in infants with TPNAC than in the control infants(P=0.033). Conclusion : The enteral intake in the third postnatal week was smaller in the infants with TPNAC than in the control infants. Thus, the incidence of TPNAC may be reduced by increasing the amount of oral intake during TPN in high risk infants.

The study was compared for soil chemical and microbial properties as well as growth of the cherry tomato (Lycopersicon esculentum var. cerasiforme) plants environmentally friendly gown for 3 years and 5 years, which had been fertigated with homemade liquid fertilizer (LF) with indigenous microorganism as an additional fertilizer. Treatment included LF with indigenous microorganism for 3 years (3-year IM-LF) and for 5 years (5-year IM-LF), with an effective microorganism for 10 years (EM-LF), which had been applied with 1,000 times of dilution in the farmhouse. IM-LF and EM-LF materials had increased pH pattern for 16 weeks, in particular for increase of 1.2 for EM-LF. IM-LF material contained slightly higher EC but similar level of 0.2 dS/m to EM-LF. For a pot experiment in the greenhouse, IM-LF treatment increased root dry weight of the cherry tomato plants. In the farmhouse experiment, IM-LF treatment increased to 7.5 of soil pH and 8.4 dS/m of EC, indicating high salt accumulation. EM-LF treatment increased to 62 g/kg of soil OM, which would have affected concentrations of macro essential nutrients, including T-N in the soil. However, the optimum soil chemical levels for growth of cherry tomato plants were observed on the IM-LF plots. EM-LF treatment increased number of bacteria and actinobacteria in the soil. EM-LF treatment increased concentrations of macro essential nutrients in the plants, except for P, with similar nutrient concentrations observed between 3-year IM-LF and 5-year IM-LF-treated plants. Leaf SPAD and PS II levels decreased in the plants treated with 3-year IM-LF. EM-LF treatment increased leaf width and length, number of leaves, canopy area, plant height, and stem diameter in the mid-term stage of growth, which were not significantly different between the treatments. EM-LF treated-plants had two times higher leaf dry weight than those of values observed on the IM-LF plants, which was the opposite result observed on the number of fruit.

The purpose of this study was to investigate the effects of green tea on hepatic antioxidative defense system and recovery of muscle fatigue in rat after aerobic exercise. Male Sprague-Dawley rats weighing 150$\pm$ 10 g were randomly assigned to one normal (N) group and aerobic exercise training groups. Exercise training groups were classified into two groups: training (T) group and green tea (TG) group which were supplemented the distilled water and green tea extracts by dringking water during experimental periods, respectively. The experimental rats in exercise training groups (T and TG) ran on a treadmill 30 min/day at a speed of 28 m/min (7% incline) 5 days/week or were cage confined (Normal group) for 4 weeks. And rats were sacrificed with an overdose of pentobarbital injection just after running. Hepatic xanthine oxidase (XOD) activities were not significantly different among three groups. The activity of superoxide dismutase (SOD) in T group was no significant difference from N group, but those of TG groups were significantly increased, compared with that of T group. Hepatic glutathione peroxidase (GSHpx) activites of TG groups showed a similar tendency to that of normal group, but it was increased to 20% in TG group, compared with normal group. The reduced glutathione (GSH) contents in liver was not significantly different from that of any three group. The oxidized glutathione (GSSG) contents in T group was increased to 69%, compared with the normal group, but TG group significantly decreased, compared with the T group. The ratio of GSH/GSSG in liver of T group was lower than that of normal group, but those of TG group was a similar tendency to that of normal group. Contents of thiobarbituric acid reactive substance(TBARS) in T group was increased to 52%, compared with that of normal group but those of TG group were recovered the normal level. Contents of hepatic glycogen in T group were decreased to 23% compared with those of normal group, while that of TG group was the same as normal levels. The contents of serum lactic acid in T group were increased to 261%, compared with normal group, but those of TG group maintained the normal level by green tea supplementations. In conclusion, the effects of green tea in exercise training rats would appear to reduce peroxidation of tissue as an antioxidative defense mechanism and promote recovery of muscle fatigue.

The purpose of this study was to investigate the effect of iron supplementation on utilizations of various minerals, Ca, Mg, Na, K, Fe, Cu, Zn. Intakes, serum levels, and excretions of these minerals were analyzed and compared in rats fed diet with 100, 200, 400% of iron requirement (Fe, 2Fe, 4Fe groups) for 6 weeks. The feed intake, body weight gain and feed efficiency ratio were not significantly different among the groups. Serum Fe of 2Fe group was significantly lower than other two groups, and serum Zn of 4Fe group was highest. Mineral intakes were not significantly different among three groups. With iron supplementation, urinary excretions of Ca, Fe, Cu, Zn were elevated, but fecal excretions of minerals were not significantly different. And the daily retentions of Na and Fe were significantly elevated, but apparent absorbabilities of minerals were not significantly different. In summary, according to iron supplementation, mineral absorbabilities were not different but urinary excretions of some minerals were increased. Therefore, it could be suggested that adequate iron intake and well-balanced diet are more desirable than nutrient supplementation for mineral balance.

This experiment was carried out to analyze the effects of substrate reuse on the growth and yield of summer paprika in cyclic hydroponics. The test group was divided into a new coco slab, one year reused coco slab two year reused coco slab based on 30% nutrient solution reuse, and was performed from April 18 to November 31, 2016 for 30 weeks. As a result, plant height of early growth was that the 2 year reused slab was longer than the new slab but the final growth period was 56.58 cm shorter. First group flower position was that reused slab was shorter by 2.92 cm than the new slab and the second group flower position was 0.31 cm long. The relative internode length of early growth, when the reused slab was used, the imbalance in the late growth stage was increased compared with the use of the new slab. The number of growth nodes in the 1 and 2 year reused slab was the smallest with 27.4 nodes. However, the number of harvested nodes did not show the difference in the test group, and the ratio of harvested that the 2 year reused slab was the highest at 26.8%. The ratio of unmarketable fruit tended to increase as the growth progressed. Fresh weight was 227.7g for new slab, 219.2g for 2 year reused slab and 21.2g for 1 year reused slab. The dry weight of the new slab increased with the reuse of the slab. It was 17.13g for new slab, 18.26g for 1 year reused, and 19.28g for 2 year reused. The average water content of the entire growth period was smaller as the slab was reused, and the 1 year reused slab was about 20g less than the 2 year reused slab. This trend was steadily occurring throughout the entire growing season. Especially, the reused slab for 1 year was less than 60g after 3 groups compared to other test groups. In conclusion, If will control seriously occurrence of unmarketable fruits by weakening after medium growth in summer-cultivated paprika in EC-based recycling hydroponic cultivation with reused cocopeat substrate, It is not what I have to worry that decrease of the yield and deterioration of the quality due to the change of physical and chemical properties of the slab and the pathogenic bacteria infection.

There are several candidate genes in genetic study of alcoholism. Among them, allelic associations have been reported between MAOA CA repeat polymorphism and alcohol dependence, recently. And also, several studies have been investigated genotype-phenotype relationships between MAOA CA repeat polymorphism and clinical manifestations. The authors tried to identify differences in allelic frequency of MAOA CA repeat polymorphism between alcohol dependence and controls, and in behavioral trait and clinical characteristics according to MAOA CA repeat polymorphism. We also tried to investigate genotype-phenotype relationships between MAOA CA repeat polymorphism and behavioral trait such as aggression. We examined 49 male patients with alcohol dependence(DSM-IV) who had been admitted in Yong-In Mental Hospital from June 1st 1998 to October 31th 1998. We performed semistructured interview for demographic and clinical characteristics. Self-report questionnaire for BDHI(Buss-Durkey Hostility Inventory) was given to all subject at least 4weeks later after admission. Using polymerase chain reaction and polyacrylamide gel electrophoresis, MAOA CA repeat polymorphism were observed in 52 male controls and 49 male patients with alcohol dependence. We devided alcoholic patients into two groups according to allelic length of MAOA CA repeat polymorphism ; alcoholics with short alleles(${\leq}$119bp, N=20) and alcoholics with long alleles(${\geq}$123bp, N=29). T-test, ${\chi}^2$-test and Fisher exact probability test were used for statistical analysis. There were no significant differences in frequency of each allele and short and long alleles of MAOA CA repeat polymorphism between alcoholics and controls. But there were significant differences in clinical symptoms and behavioral trait between alcoholics with short and long alleles. In clinical symptoms, alcoholics with long alleles used alcohol more frequently during one month before admission, had much more maximum amount of beer drinking and reported withdrawal seizure more frequently than with short alleles. In contrary, alcoholics with short alleles expressed depressed mood and guilty feeling more frequently and wanted complete abstinence as a treatment goal more frequently than with long alleles. In behavioral trait, alcoholics with long alleles had higher total aggression score and showed much more self-assertive attitude(subscale of expression of aggression) than with short alleles. Allelic length of MAOA CA repeat polymorphism was correlated with self-assertive attitude and accounted for 9% of the variance of self-assertive attitude. And also, predictable variables of allelic length of MAOA CA repeat polymorphism were drinking frequency and self-assertive attitude. Our findings suggest that MAOA CA repeat polymorphism may provide some behavior modifying role especially in self-assertive attitude and indirect symptom modifying role in Korean male alcoholics.
