Purpose: This study was to investigate the effect of isometric exercise and active stretching on joint function in patient with osteoarthritis. Methods: 30(M=1, F=29) subjects with osteoarthritis were divided in three groups: control group, quadriceps isometric exercise group, and hamstring active stretching group. After 6 weeks treatment, ROM(range of motion) and LSS(lysholm scoring scale) were measured. Results: There was a significant increase in knee flexion, extension in post-treat of quadriceps isometric exercise group and hamstring active stretching group(p<0.05). There was a significant increase in LSS in post-treat of quadriceps isometric exercise group and hamstring active stretching group(p<0.05). Conclusion: This study shows that both the active stretching exercise and the quadriceps isometric exercise effectively promote the range of knee extensions for osteoarthritis patients. Also, as measuring the ROM of knee flexion and extension by exercise methods, there is significant increase from knee flexion and extension in both hamstring stretching exercise group and quadriceps isometric exercise group. The increase of the range of knee is more effective in the exercise of knee extension with hamstring stretching exercise groups. And it is found that there are some difference between the experimental group and controlled group in statistics. As it is concerned with the function of knee extension, supporting and squatting are more effective to promote the both knee extension and flexion in its range. Therefore, this shows that the hamstring stretching exercise is required in general with enforcing the quadriceps at a sickbed in the present.

This study investigated the crude protein and amino acid contents of local agricultural products widely and specifically grown in Korea, including 25 vegetables and 13 fruits. The crude protein content of vegetables and fruits ranged from 0.46 to 6.53% and 0.29 to 2.23%, respectively. Totally, 17 types of amino acids were found in most samples. The total amino acid content of vegetables and fruits ranged from 457.38 to 9,303.18 mg% and 368.82 to 3,118.75 mg%, respectively. The total amino acid contents of garlic and passion fruit was higher compared to other vagetables and fruits. The calibration curves of the standard components showed good linearity ($r^2$>0.99), except Met ($r^2=0.989$). The limits of LOD and LOQ were in the range 0.034 to $0.991{\mu}g/mL$ and 0.009 to $0.474{\mu}g/mL$, respectively. The results of the study can serve as a fundamental source of information regarding crude protein and amino acids contents in food, for diet planning.

Background: Although aortic valve repair can reduce prosthesis-related complications, rheumatic aortic regurgitation (AR) caused by leaflet restriction is a significant risk factor for recurrent AR. In this study, we evaluated the long-term results of the leaflet extension technique for rheumatic AR. Methods: Between 1995 and 2016, 33 patients underwent aortic valve repair using the leaflet extension technique with autologous pericardium for rheumatic pure AR. Twenty patients had severe AR and 9 had combined moderate or greater mitral regurgitation. Their mean age was $32.2{\pm}13.9$ years. The mean follow-up duration was $18.3{\pm}5.8$ years. Results: There were no cases of operative mortality, but postoperative complications occurred in 5 patients. Overall survival at 10 and 20 years was 93.5% and 87.1%, respectively. There were no thromboembolic cerebrovascular events, but 4 late deaths occurred, as well as a bleeding event in 1 patient who was taking warfarin. Twelve patients underwent aortic valve reoperation. The mean interval to reoperation was $13.1{\pm}6.1$ years. Freedom from reoperation at 10 and 20 years was 96.7% and 66.6%, respectively. Conclusion: The long-term results of the leaflet extension technique showed acceptable durability and a low incidence of thromboembolic events and bleeding. The leaflet extension technique may be a good option for young patients with rheumatic AR.

The ability of sunflower, bean, green perilla, and sesame to attract Metcalfa pruinosa was tested in both laboratory and field conditions. In the laboratory experiment, sunflowers showed the highest attractiveness to M. pruinosa nymphs and adults. These results were the same as those in the field experiment. Sunflowers showed the highest attractiveness among the four candidates as a trap plant for M. pruinosa, with comparable average attractiveness values for nymphs and adults to those in the laboratory. Young beans also showed high attractiveness to M. pruinosa, albeit lower than those of sunflowers. However, the attractiveness of mature beans was low. Sunflowers consistently (P < 0.05) showed significantly higher attractiveness than that of the other three plants, regardless of plant age. Thus, sunflowers would serve as a good trap plant for both the nymphs and adults of M. pruinosa.

The purpose of this study was to examine the quality characteristics of cookies made with Angelica gigas Nakai fermented by Lactobacillus paracasei. As the content of Angelica gigas Nakai fermented by L. paracasei (AFL) powder increased, the pH of the cookies decreased from 6.3 to 5.2. There was no significant difference in the moisture content depending on AFL powder content. The content of reducing sugar also increased with increasing AFL powder content. Regarding the surface color of the cookies, the L- and b-values decreased with increasing AFL powder content, whereas the a-value increased. As the AFL powder content increased, the total polyphenol content and ABTS and DPPH radical scavenging activities significantly increased. Cookies with 8% AFL powder (AC8) had the highest levels of 107.16 mg%, 38.69%, and 65.56%, respectively. The texture, adhesiveness, and cohesiveness of the cookies with various AFL powder levels were not significantly different, and hardness, springiness, gumminess, and chewiness showed no tendencies toward changes. Taken together, these results showed that when AFL powder was added to cookies, bioactivities such as antioxidant activity increased, making AFL powder a good material with high potential for use in commercially baked products.

Purpose: This study aimed to investigate the effect of changing the kilovoltage peak (kVp) on the radiographic assessment of dental caries. Materials and Methods: Seventy-five extracted posterior teeth with proximal caries or apparently sound proximal surfaces were radiographed with conventional E-speed films and a photostimulable phosphor system using 60 kVp and 70 kVp for the caries assessment. The images were evaluated by three oral radiologists and compared with the results of the stereomicroscope analysis. Results: No statistically significant difference was found between 60 kVp and 70 kVp for the caries detection, determination of caries extension into dentin, and caries severity in either the conventional or the digital images. Good to very good inter-observer and intra-observer agreements were found for both kilovoltage values on the conventional and digital images. Conclusion: Changing the kilovoltage between 60 kVp and 70 kVp had no obvious effect on the detection of proximal caries or determination of its extension or severity.

A extension of the high boost voltage-lift DC-DC converter with large conversion ratio has been proposed in this paper. The proposed extension is combined the switched-inductor cell (SL-cell) and modular voltage cell (MV-cell). The proposed structure can achieve the large voltage conversion without high duty-cycle and the low voltage of the components. Moreover, the PID controller for novel SL-MV voltage-lift DC-DC converter also introduces. This technique a good-performance output voltage can kept constant with an good transient performance when the output load is suddenly changed. In order to prove the theoretical analysis, the experimental setup has been built for the DC load of $150[{\Omega}]$ and $300[{\Omega}]$. In addition, the transient of output voltage has been tested to determine the controller. Experimental results validate the effectiveness of the theoretical analysis proving the satisfactory converter performance.

Two strains Pleurotus eryngii 'Aeryni' and 'Na' carrying superior traits of a pileus and a earliness of harvest were selected to improve previously bred strains by single crosses. New hybrid, Aeryni 3 (Aeryni10 ${\times}$ Na5) showed superiority to other hybrids in yield, fruit body shape and days for harvest. The new strain, Aeryni 3 was harvested earlier than Keunneutari No. 2 by 2~3 days, and yielded 110.5 g/bottle (850 mL) which was 108% of that of Keunneutari No. 2. The ratio of diameter of pileus and stipe was 1.8 indicating that new stain will be likely low damage rate of fruit body during a distribution, and that was better than 2.1 of Keunneutari No. 2. A sensory test of taste of the new strain showed that 84.7% of evaluation panels selected "very good" while that of Keunneutari No. 2 was 55.5%. In purchasing intent test, 86.9% of panels will buy the new stain whereas 46.8% will buy Keunneutari No. 2 implicating that the new strain will likely be more marketability than previously bred strain.

Kenaf (Hibiscus cannabinus L.) was recognized as a potential source of forage. But the domestic cultivation techniques are not set standards yet. So we tested the basic culture techniques during 2012~2013 for getting a high yield and good grade forage production system. The best seeding method for mechanized planting (corn planter used) was hill seeding with $20{\times}20cm$ seeding distance. When we treated hill seeding with $20{\times}20cm$, the yield what we could get was 13,641 kg/10a and it was 32% more than that of conventional practice hill seeding with $20{\times}30cm$ seeding distance. The proper seeding date for getting high yield was May 1. In May 1, the yield per 10a was reached 13,423 kg, and it was 30% more than that of seeding at May 30. More over the crude protein content which was important factor for determinating forage nutritive value was 12.7% and it was higher 1.8% (relatively 16.5% high) than that of May 30 seeding. The most effective herbicide for kenaf was Fluazipof-p-butyl. It's herbicidal rate was 97% and phyto-toxicity was less than 5%. Regional adaptability for Jeollabuk-Do including Imsil Gun, Kochang Gun and Sunchang Gun were identified that the stable cultivation were possible in these area with average yield 12,400 kg/10a and it was about 1.7 times as compared to corn harvest.
