Purpose : To describe normal anatomy and compare the differences of external genital organs and urethra on MR imaging in pre- and postmenopausal women. Materials and Methods : A total of 19 pre- and 18 postmenopausal healthy women underwent pelvis MR imaging at 1.5 T. Two radiologists retrospectively scored and compared the image quality of female external genitalia and urethra on axial T2-weighted images (T2WI) and axial fat-suppressed contrast-enhanced T1-weighted images (FSCE-T1WI) by using Wilcoxon signed ranks test. The radiologists compared the wall thickness or size of external genital organs and urethra on FSCE-T1WI between two groups by using Student t test. Results : Image quality was better with FSCE-T1WI than with T2WI in all subjects (p < 0.05). The vestibular bulb, clitoris and labium minor were more clearly visualized on FSCE-T1WI in premenopausal subjects rather than in postmenopausal subjects (p < 0.05). The urethra had a target-like appearance with three layers in premenopausal and postmenopausal subjects. Postmenopausal subjects were observed to have significantly smaller vaginal wall thickness, urethral wall thickness and vestibular bulb width than premenopausal subjects (p < 0.05). Conclusion : The anatomy and morphologic changes of female external genital organs and urethra were well discernible on FSCE-T1WI.
Garlic sprouts can provide data on functional and food processing materials. This study compared the leaves, bulbs, and roots of garlic sprouts grown on smart farms during two growth periods (20 and 25 days). In addition, data for garlic bulbs grown in open fields were presented as reference materials. All garlic sprouts' total free sugar content decreased as the growth period increased. All plant parts' total organic acid content decreased as the growth period progressed, except for the root section. Potassium, phosphorus, and sulfur content increased during growth in all parts of the garlic sprouts. Alliin content decreased in all parts of the plant over time, whereas thiosulfinate content increased in the roots but decreased in the leaves and bulbs. Total polyphenol content increased in all parts of the plant during the growth period, except for the bulb, whereas the flavonoid content did not change significantly over time. The 2,2-diphenyl-1-picrylhydrazy (DPPH) and 2,2'-azinobis (3-ethylben-zothiazoline 6-sulfonate) (ABTS) free radical scavenging activities, as well as the superoxide dismutase (SOD)-like activity of garlic sprouts were 37.45-65.47%, 59.12-89.81%, and 89.52-98.59%, respectively. These activities tend to decrease during the growth period. Here, we showed that garlic sprouts have higher levels of functional substances and physiological activities than general garlic sprouts. It was also determined that a growth period of 20 days was suitable for garlic sprouts. Data for research on functional and food-processing materials can be obtained by analyzing garlic sprouts produced by smart farms.
This study assessed the effects of treatment with sap extract from onion residues postharvest and purslane on the quality and quantity of organic onions. At the bending stage, onions treated with the sap extract showed vigorous growth, with higher plant heights, more leaves, and longer sheath lengths than untreated onions. The onion yield was significantly increased when the plant was treated with extracted sap as compared with that of untreated plants (p<0.05). The bulb weight distribution of onions in the mixed onion and purslane treatment was also significantly increased (~300 g) as compared with that of the other treatment (p<0.05). Except for CaO and S, the mineral content of the onions produced from plants treated with the onion and purslane extract mixture was higher than those of onions in the other treatment. The hardness of onions produced from plants treated with the onion and purslane extract was significantly increased (8% and 20%, respectively) as compared with that of onions produced from plants treated with the onion extract only or no treatment (p<0.05). However, there was no significant difference in the sugar contents of the onions produced from extract-treated and nonextract-treated plants. Postharvest, the content of inorganic components (phosphate, calcium, sulfuric acid, and manganese) was higher in soil treated with the onion extract than in soil treated with the onion and purslane extract and non-treated soil. It can be concluded that residues left after onion harvests and purslane extract can be used as natural and environmentally friendly materials for the cultivation of organic onions.
This study was carried out to fortify the antimicrobial activity of yogurt by adding garlic juice to it. A raw garlic bulb was grated and heated with Glycyrrhiza uralensis to improve its antimicrobial activity and palatability. Yogurt was made with 0, 4, 8, and 12% garlic juice, and was evaluated in terms of its lactic starter growth, physico-chemical characteristics, growth inhibitory activity against Staphylococcus aureus KCCM 40510, and sensory characteristics. The garlic juice significantly increased the growth of the yogurt starter (p<0.05), which was highest with the addition of 4% garlic juice. Significant (p<0.05) inhibition of S. aureus KCCM 40510 occurred with the addition of 12% garlic juice. The preference was lowered with the addition of garlic juice, but the addition of 4% garlic juice showed no significant difference (p>0.05). To increase the antimicrobial activity of yogurt with the addition of garlic juice, further studies on the increase in the palatability of garlic juice are necessary.
Introduction : Exercise has been suggested as an important nursing strategy in which to help elderly maintain functional performance and to enhanced quality of life. Most of exercise study has been reported on fitness exercise such as walking, swimming, dance etc for health of elderly. There have been few reports about exercise on the promotion of small and fine movement of elderly. The purpose of this pilot study was to determine an effect of 6 weeks hand and finger exercise in home to improve hand muscle strength such as grip strength and finger pinch pressure. Materials and Methods Design: This pilot study was used one group pre and post-test design. Sample: Twelve elderly women above 60 years of age or older living in community were selected by convenient sampling. Procedure: Signed informed consent was obtained prior to participate in this study. The authors met elderly and taught hand and finger exercise, daily a week for 6 weeks, within 30 minutes per session. But exercise frequency and strength were not same. Instruments: Left and right grip strength were measured by Bulb Dynamometer(made in USA) and left and right pinch pressure were measured by Baseline Hydraulic Pinch Gauge(made in USA). Data analysis: Discriptive data analyses were performed on all variables. Wilcoxon matched-pairs Signed-Ranks test were used to find difference of grip strength and pinch pressure between pre and post exercise using SPSS 10.0 for Window. Results: Samples age ranged from 60 to 73, Mean age was 65.3. All were women. Ten elderly were diagnosed osteoarthritis and one had DM. After six weeks hand and finger exercise, Left and right grip strength were higher than those of before exercise(Z=-2.667, P<0.01 ; Z=-3.065, p<0.01). And left pinch pressure after hand and linger exercise were higher than that of before pinch pressure (Z=-2.315, p<0.05). But Right pinch pressure was not shown significant change(Z=-1.099, p>0.05). Conclusions: Although this study was limited by the sample size and design, the findings provide some important implications for community based exercise nursing intervention. Short term (six weeks) exercise of hand and linger is shown to be useful as nursing intervention to maintain routine daily activities such as eating, writing, grip something for elderly.
Pink root disease of onion, a known worldwide constraint upon onion production, significantly reduces crop levels in the main Korea cultivation area. In order to examine the effect of flooding on incidence of pink root disease caused by Pyrenochaeta terrestris and on onion growth and on populations of soil fungi, field experiments were conducted during two seasons, 2003/04 and 2004/05 at Onion Research Institute. Populations of soil fungi from fields were assayed on selective media. Flooding treatment was effective in reducing populations of P. terrestris, Pythium spp., and Rhizoctonia sp. in soil; fungal populations in soils flooded for 90 days were reduced to 1/2 to 1/3 of those in non-flooded soils. In nursery bed, protective activities of soils flooded for over 60 days were 93.5 to 99.2% and their pink root incidences were less than 5%, which were 1/11 to 1/18 of that in control. Increased yield of onion bulbs was associated with control of soil borne pathogenic fungi by flooding treatments. As flooding period was prolonged, bulb grade showed the tendency to increase. Soil flooding for over 60 days resulted in effective disease control, facilitated accurate planning of plant population in the field, extension of the growing-season and consequently higher yields of better quality.
This experiment investigated the characteristics of salted and fresh Chinese cabbages of different cultivars and using various cultivation methods. We measured the numbers of leaves, sizes, thicknesses, moisture contents, and firmness qualities of fresh Chinese cabbage grown in a plastic house, and outdoors. 'The bulb sizes, leaf thicknesses, and moisture contents of leaves were higher after plastic house cultivation than after growth in the field. Plastic house culture increased the growth rate of Chinese cabbage. Firmness and osmolarity showed better values after outdoor cultivation, however. The growth rates and the levels of chemical components were affected by interactions between cultivation methods and cultivars of Chinese cabbage. The salt levels of salted Chinese cabbage were 1.21.7% (w/w) after cabbages cultivated outdoors were preserved, and 0.91.2 % (w/w) after vegetables grown in a plastic house were treated. The quality properties of postharvest Chinese cabbages after salting varied with cultivation method even when the same cultivars of Chinese cabbage were used. The salt contents of salted Chinese cabbage thus varied with different cultivation methods. The results indicate that the properties of Chinese cabbage vary with the culture systems adapted.
Onion has been reported to contain various organosulfur compounds which have antibiotic and anticarcinogenic properties and flavonoid like quercetin which is a valuable natural source of antioxidants. Carbohydrates in onion constitute about 80% of dry matter, and the major non-structural carbohydrate of onion bulb is fructo-oligosaccharides, well known as fructan, followed by glucose, fructose, and sucrose. The sugar concentration is associated with dormancy and storage life of onion, occurring as decrease in glucose, fructose and fructan, particularly towards the end of storage. Forced air pre-drying for 15-20 days at room temperature is an essential procedure to reduce freezing injury and sprouting, then onion bulbs can be stored at $0^{\circ}C$ for 6 months to control sprouting and decay. Bacterial soft rot caused by $Erwinia$ and $Pseudomonas$ is the main postharvest disease when the bulbs are infected with the bacteria and stored at room temperature. Browning in sliced onion is due to oxidation of phenolic compounds by polyphenol oxidase and it can be inhibited by citric acid treatment, packing with nitrogen gas, and polyethylene film.

A patient who went through maxillectomy can have soft palate defects including oronasal fistulas and suffer from dysphagia and dysarthria due to velopharyngeal insufficiency. This defect causes the food to enter nasal cavity and creates hypernasal sound which debilitates a quality of life. An obturator can rehabilitate the substantial oral tissue defects. The maxillary obturator separates the nasopharynx from the oropharynx during speech and deglutition by closing of the defect. For edentulous obturator patient, it is difficult to obtain proper retention due to reduced peripheral sealing. Therefore, the contours of the defects must be used to maximize the retention, stability, and support. Hollow type obturator can improve physiologic function by reducing weight than the traditional obturator. This case report describes a patient with hemi-maxillectomy who recovers mastication, speech, deglutition, and appearance with a maxillary obturator using physiological border molding of the velopharyngeal area and double-processing method.

BACKGROUND: In the month of January 2018, fine dust alerts and warnings were issued 36 times for $PM_{10}$ and 81 times for PM2.5. Air quality is becoming a serious issue nation-wide. Although interest in air-purifying plants is growing due to the controversy over the risk of chemical substances of regular air-purifying solutions, industrial spread of the plants has been limited due to their efficiency in air-conditioning perspective. METHODS AND RESULTS: This study aims to propose a vegetation-based bio-filter system that can assure total indoor air volume for the efficient application of air-purifying plants. In order to evaluate the quantitative performance of the system, time-series analysis was conducted on air-conditioning performance, indoor air quality, and comfort index improvement effects in a lecture room-style laboratory with 16 persons present in the room. The system provided 4.24 ACH ventilation rate and reduced indoor temperature by $1.6^{\circ}C$ and black bulb temperature by $1.0^{\circ}C$. Relative humidity increased by 24.4% and deteriorated comfort index. However, this seemed to be offset by turbulent flow created from the operation of air blowers. While $PM_{10}$ was reduced by 39.5% to $22.11{\mu}g/m^3$, $CO_2$ increased up to 1,329ppm. It is interpreted that released $CO_2$ could not be processed because light compensation point was not reached. As for the indoor comfort index, PMV was reduced by 83.6 % and PPD was reduced by 47.0% on average, indicating that indoor space in a comfort range could be created by operating vegetation-based bio-filters. CONCLUSION: The study confirmed that the vegetation-based bio-filter system is effective in lowering indoor temperature and $PM_{10}$ and has positive effects on creating comfortable indoor space in terms of PMV and PPD.
