  • Curvularia leaf blight of creeping bentgrass (Agrostis stolonifera) putting green by caused Curvularia trifolii was observed in Hapcheon, Korea. In July to September 2014, curvularia leaf blight developed on leaf blades of creeping bentgrass as small water-soaked lesions that subsequently turned into dark-colored, necrotic spots. The spots were expanded and became gray, grayish-brown, or light brown, circular to oblong lesions with purple to dark brown borders that often were surrounded by a yellow halo. The necrotic lesions coalesced, became irregular in shape and caused tip or complete blighting of the leaves. Blighted leaf blades appeared grayish-white to tan. The fungus was identified by morphological characters and 16S rDNA sequencing as C. trifolii. Conidia of the pathogen were short, with predominantly 3-septa, straight or often curved, with end cells frequently paler than intermediate cells. Size of the 3-septate conidia in culture are $26{\sim}28{\times}11{\sim}12{\mu}m$. Pathogenicity of the fungus was proved by artificial inoculation on the host. This is the first report of C. trifolii causing leaf blight on creeping bentgrass in Korea.

  • The aim of this study was to evaluate the effect of kale (Brassica oleracea acephala) juice supplementation on serum lipid levels and phospholipid (PL) fatty acid compositions in hypercholesterolemic men. Thirty-two men with hypercholesterolemia (>200 mg/dl) were recruited among the faculty and staff at Y University after annual health examinations. The subjects consumed 150 ml of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed before and after supplementation, respectively, to ensure that the subjects maintained their usual diet and lifestyle throughout the intervention. Serum concentrations of HDL-cholesterol and the ratio of HDL-cholesterol to LDL-cholesterol were significantly increased (p<0.001) after intervention. Serum LDL-cholesterol concentration and atherogenic index were significantly reduced (p<0.001). Levels of 12:0, 14:0, $18:1{\omega}9$, $18:3{\omega}6$, and sum of monounsaturated fatty acids (MUFA) in serum pholspholipid (PL) were significantly increased, while $22:4{\omega}6$ level was significantly reduced (p<0.05). It can be speculated that kale juice, containing large amounts of antioxidant nutrients, contributes to changes of serum-PL-fatty acid compositions and the improvements of serum lipid profiles. This study demonstrates the supplementation of regular meals with kale juice may favorably affect serum lipid profiles and serum-PL fatty acid compositions and, hence, could lower the risks of coronary artery disease in men with hypercholesterolemia.

  • The purpose of this study was to analyze the effects of Hatha Yoga exercise on the body composition, serum lipids, and health-related fitness of obese middle-aged women. The subjects in the Hatha Yoga exercise group (n=9) were 18 obese middle-aged women that trained for 16 weeks and a control group (n=9). Body composition, serum lipids, and health-related fitness were measured in all of the subjects before the start of the training program and at the end of the 16 weeks. The findings of this study were as follows. Body weight, %BF, BMI, WHR, VFA, TC, TG, LDL-C, FFA, and HOMA-IR significantly decreased, whereas LBM, HDL-C, grip strength, back strength, push-ups, sit-ups, Harvard step test, and sitting trunk flexion significantly increased in the Hatha Yoga exercise group after 16 weeks. Therefore, regular and continuous Yoga exercise was effective in improving body composition, serum lipids, and health-related fitness. Consequently, Yoga exercise could be effective for preventing cardiovascular disease caused by obesity in middle-aged women.

  • When expressing Christ visually in the medieval Christian painting, the most important issue was how to express the divinity as Son of God and the humanity as attribute of human in a balanced manner. The purpose of the study is to examine both formative and symbolic characters of divinity and humanity on the Christ's body and clothes in the Medieval paintings, Transfiguration of Christ. In the paintings, Christ's body is definite evidence to show both his divinity and humanity. In connection with the body, the clothes reveal Christ's humanity and divinity as well. Through this research, the study found that the divinity and humanity on the Christ's clothes in the Transfiguration of Christ were as follows: Blue, gold, purple, white and bleaching effect are the emblem of divinity, and red and color contrast effect with a high chroma stand for humanity of Christ. In addition, unstructured wrinkles of clothes reveal Christ's divinity, on the other hand, structured drapery shows his humanity through emphasizing volume of the body. Finally, divinity of Christ is shown on the gold clavus and red clavus intensify his humanity. Medieval Christian paintings are products planned out to express Christ's dual nature. There is a significance that the paintings represent the profession of painter's faith and the dogma of the era. Furthermore, they suggest the importance of the image to deliver the abstract concepts by visualizing.

  • Purpose: To evaluate the results and prognosis of operative repair to acute rupture of achilles tend on associated sports injury. Materials and Methods: 21 cases were surgically treated and average follow-up period was 1 year and eight months. The forth decade was most common with $55\%$ and soccer was most common in sports with 5 cases. End-to-end suture of ruptured achilles tendon was performed, and paratendinous structure was wrapped sufficiently. Postoperatively. ankle was plantarflexed for 6 weeks with longleg cast. And then 2 weeks interval, short leg cast with equinous position was conversed to functional position. About 10 weeks after operation, ankle was recovered to right angle. Hooker scale was used to evaluate the results. Results: Compared to normal side, heel-floor distance of ruptures side was decreased 0.7 cm in average, and 0.8 cm was deceased after 20 times weight loaded dorsiflexion. Mid-calf circumference was deceased 0.3 cm, and active dorsiflexion and plantar flexion of ankle was decreased each 3 and 5degree. 16 cases showed ‘excellent’result and 5 cases showed ‘satisfactory’. There was no complication, such as re-rupture or infection at operation site. Conclusion: After end-to-end operative repair to achilles tendon, sufficient wrapping of paratendinous structure is efficient for healing and prevention of postoperative adhesion. And serial dorsiflex-ion cast change is considered to be a successful treatment for preventing residual equinus deformity.

  • Various types of shearing devices which may be a substitute for the conventional beams in stow nets were considered, and then tentatively named "the zonal canvas type of stow net" having the shearing device made of zonal canvas was devised. A 1/3 model of the net was made and experimented at sea. Converted to the full scale, the measured water resistance R(kg) of the net was given by $R=5.6{\times}10^{3}V^{l.5}$ or $R=3.5\frac{d}{l}{\lambda}_b{\lambda}_l\;V^{1.5}$, where V is the water velocity (m/sec), d the diameter of netting bars, l the length of the bars, ${\lambda}_b$ the stretched circumference of net mouth (m), ${\lambda}_l$ the length of net stretched. The net height kept about $83\%$ of the side rope length regardless of the variation of V and the net breadth kept a value over $90\%$ of the head rope length until V reached 1 m/sec. These results were very successful according to expectation, but the conventional netting was requested a further improvement. Therefore, the netting was newly designed to have smaller size of meshes in the vicinity of net mouth and larger hanging ratio breadthwise. With the netting a full scale net was made and experimented by a stern trawler. The experiment gave a net breadth over $95\%$ of the head rope length until V reached 1m/sec and showed no faults in the net. But the net operation by the stern trawler was ascribed an inconvenience to its narrow breadth of stern slip way.

  • Characteristics of ostrich egg shell and optimal ashing conditions for preparation of calcium lactate were investigated. Average weight, girth, and length of ostrich egg shell with membrane (OESM) were 255.17 g, 39.50 cm, and 15.20 cm, respectively. Ostrich egg shell without membrane (OES) contained 0.35% moisture, 40.98% Ca as a maior mineral, 2.43% protein, and 235.0 mg/100 g of amino acids. Optimal ashing times for preparation of white-colored ashing powder from OES were 12 hr at $700^{\circ}C$, 80 min at 80$0^{\circ}C$, and 15 min at 90$0^{\circ}C$, respectively. These ashing conditions resulted in ashing powder with yields of 54.5~54.6% and color values of 97.26 ~97.51 for $L^{*}$, -0.30~-0.34 for $a^{*}$, and 0.63~0.98 for $b^{*}$. Ashing powders, from three different particle size ranges of OES, did not show significant differences in yield.eld.d.

  • Metabolic syndrome is associated with risk of developing cardiovascular disease and type 2 diabetes, and incidence of metabolic syndrome is showing an increasing trend. Recently, coffee intake is argued to have an effect on the gut-brain axis, and it is widely recognized has being associated with many beneficial effects, including those related to metabolic imbalance. However, it is essential to understand how the dietary aspects of coffee intake and type of coffee intake affect diet and overall health. The association between coffee consumption and health is still controversial, and the average body weight of the Korean population is increasing. Therefore, this study focused on analyzing the effects of instant coffee (particularly instant coffee mix) in Korea, especially with respect to metabolic syndrome. The study was conducted on participating subject's that visited Sun-Han hospital, and instant coffee mix intakes and metabolic risk factors during the study period were examined from July 2015 to June 2016. The results showed that waist circumference (r=0.405, P=0.036) and serum triglyceride level (r=0.435, P=0.023) were positively correlated with instant coffee mix intakes. In addition, instant coffee mix intakes were significantly associated with serum triglyceride level in subjects who consumed more than 1 cup/d of coffee (P<0.05). Therefore, subjects should be careful about fat intake and be educated about the type and frequency of coffee intakes.

  • A meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. This study will find meaningful mediator variables for criterion variables that affect between pre and post in metabolic syndrome studies, on the basis of the results of a meta-analysis. We reviewed a total of 36 studies related metabolic syndrome published in Korean journals between 2000 and 2015, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study. In this meta-analysis, the path between pre and post in waist circumference showed the biggest effect size (r = .420). The second biggest effect size (r = -.402) was found the path between pre and post in high density lipoprotein cholesterol. By the way, one the smallest effect size (r = .234) was obtained the path between pre and post in diastolic blood pressure. Thus, we present the theoretical and practical implications of these results and discuss the differences between these results through a comparative analysis with previous studies.
