Background: The purpose of this study is to investigate the effect of plantar flexor on muscle fatigue and endurance when two different sport tapes are applied. Design: Cross-sectional design. Methods: Fifty-one healthy adults were randomly assigned to dynamic taping group (n=17), kinesio taping group (n=17), and control group (n=17). The dynamic taping group used the dynamic tape. The kinesio tape group used the kinesio tape, and the control group doesn't used tape. Every group performed heel rise test and sEMG for every during pre-test and post-test. To evaluate plantar flexor endurance, the number of times was measured during the heel rise test. Results: The number of heel rises increased significantly in the post-test in dynamic taping group compared to the pre-test, and In comparison between groups, the number of heel rises significantly increased in dynamic taping group compared to kinesio taping group and control group. PEF value was significantly increased in the post-test compared to the pre-test in dynamic taping group, and there was a significant difference between the three groups according to the taping application. Conclusion: The results of this study confirmed that dynamic taping was effective in musclular fatigue and endurance on plantar flexor in healthy adults. Based on these results, it is suggested that the application of dynamic tape can be suggested as one of the intervention methods for muscle endurance and muscle fatigue.

This study presents the experimental results of $CaCO_3$ formation in sand by the Enzyme Induced Carbonate Precipitation (EICP) method. Concentration of $CaCO_3$ with elapsed reaction time is calibrated by standardized procedure by measuring $CO_2$ pressure, and it increases with time towards asymptotic value. Jumunjin sand saturated with EICP solution shows that both shear wave velocity and electrical conductivity sharply increase as the reaction starts to approach to the constant values after 50 hours of reaction time. Urease concentration of 0.5 g/L exhibits 224% higher final shear wave velocity than that of 0.1 g/L. The nucleation models hint that carbonate tends to precipitate not only at grain contacts but also at grain surfaces. Regardless of urease concentration, electrical conductivity and shear wave velocity follow the unique path. The scanning electron microscopic images and X-ray computed tomographic images validate the spatial configuration of produced $CaCO_3$ in soils. 본 연구에서는 사질토에서의 EICP에 의한 탄산칼슘 침전량을 정량적으로 평가하였다. 생성된 탄산칼슘은 염산과의 반응에 수반되는 이산화탄소 기체 압력 증분을 통해 간접적으로 측정하였으며, 이는 반응이 진행됨에 따라 특정 값으로 수렴하는 경향을 보였다. EICP 용액으로 포화된 주문진표준사의 전단파 속도 및 전기전도도값은 측정된 탄산칼슘량의 수렴시간보다 선행하여 일정한 값에 도달함을 확인하였다. 결정화 모델은 탄산칼슘이 흙 입자간 접촉점과 입자표면에서 생성됨을 나타내며, 이를 통해 최종 전단파 속도 및 최종 전기전도도에 도달하는 시간과 탄산칼슘 생성량의 수렴시간 간의 불일치가 설명 가능함을 보였다. 또한, 용액 농도 0.5g/L를 이용한 최종 전단파 속도는 0.1g/L의 것보다 224% 높은 효율을 나타내었다. 더불어 효소의 농도와 무관하게 전기전도도와 전단파 속도의 상관관계가 있음을 확인하였으며 주사전자현미경과 X-ray CT 이미지 분석을 통해 생성된 탄산칼슘의 공간적 분포를 확인하였다.

The microstructures and mechanical properties of roll-bonded STS439/Al1050/STS304 clad materials were investigated after an annealing process at various temperatures. Interfacial layer was developed at the STS439/Al1050 and Al1050/ STS304 interfaces at 550℃. STS439/Al1050/STS304 clad metals fractured suddenly in a single step and the fracture decreased with increasing annealing temperatures at 450℃. After annealing at 550℃, samples fractured in three steps with each layer fracturing independently. Interfacial layers formed at 550℃ with a high Vickers microhardness were found to be brittle. During tensile testing, periodic parallel cracks were observed at the interfacial reaction layer. Observed micro-void between Al1050 and the interfacial layer was found to weaken the Al1050/reaction layer interface, leading to the total separation between Al1050 and the reaction layer.

Achalasia is characterized by failure of the lower esophageal sphincter to relax normally during swallowing and aperistaltic movement of the esophageal body. The large majority of achalasia is idiopathic, a disorder of unknown etiology with ganglion cell degeneration of esophageal myenteric plexus. Only small proportion of achalasia is secondary induced by malignant tumors. To date, the achalasia in patiet with colon cancer has not been reported. We report a case of achalasia diagnosed before the detection of colon cancer with multiple metastasis.

우리나라 양식 넙치(Paralichthys olivaceus) 육성어와 종묘의 지역별 Kudoa septempunctata 감염 현황

송준영 ( Jun Young Song ),김민정 ( Min Jeong Kim ),최혜승 ( Hye Sung Choi ),정승희 ( Sung Hee Jung ) 한국수산과학회 2014 한국수산과학회지 Vol.47 No.5

A nationwide survey was conducted to study the rate of Kudoa septempunctata parasitization in cultured olive floun-der, Paralichthys olivaceus, in Korea in 2013. Of 1107 olive flounder sampled randomly from 89 culture farms in five different regions in Korea, K. septempunctata was detected only in Jeju, where 10 of 318 fish (3.14%) were PCR positive, with genomic concentrations of 4.67×105 to 1.48×1011 rDNA copies/g by real-time PCR. Of the ten Kudoa-positive fish, K. septempunctata spores with 5-7 polar capsules were detected only in four fish. No samples of K. septempunctata were detected in olive flounder from the other regions surveyed. Furthermore, K. septempunctata was not detected in 326 samples of olive flounder seeds sampled from 39 hatcheries in seven different regions in Korea. Therefore, the parasite infection is restricted to Jeju and K. septempunctata infection is not spread from hatcheries.

Lutein Modulates Th2 Immune Response in Ovalbumin-Induced Airway Inflammation

Lutein은 식물에서 발견되는 carotenoid 계열에 속하는 물질로 항산화 기능을 가지고 있는 것으로 널리 알려져 있지만, 호흡기 질환과 관련하여 아직까지 lutein의 효능과 작용 기작이 잘 알려져 있지 않다. Ovalbumin (OVA)으로 유도한 천식(asthma) 생쥐모델에서 lutein은 기도 과민성을 억제하였고, 기관지 폐포 세척액에서 OVA의 감작에 의하여 증가한 각종 염증성 지표들을 감소시켰다. 또한, OVA의 감작에 의하여 증가한 제2형 협조 T 세포(Th2 cell)의 증가된 반응을 약화시키는 결과를 볼 수 있었다. 본 실험에서 lutein이 ovalbumin (OVA)으로 유도한 천식 생쥐 모델에서 제 2형 협조 T세포의 싸이토카인과 유전자 발현을 조절할 수 있는 면역약리학적 기능을 할 수 있는 물질로서의 가능성이 있음을 확인할 수 있었다. The general term flavonoids is often used to categorize a family of natural compounds that are highly abundant in all higher plants, and which in recent years have attracted scientific interest as therapeutics. Lutein is a xanthophyll and one of 600 known naturally occurring carotenoids. It is found in green vegetables such as spinach and kale, and has been demonstrated to exert anti-inflammatory activities. However, its anti-allergic effect in the Th1/Th2 immune response is poorly understood. In this study, we attempt to determine whether lutein regulates inflammatory mediators in an ovalbumin (OVA)-induced murine asthma model. To address this, mice were sensitized and challenged with OVA, and then treated with lutein before the last OVA challenge. Administration of lutein significantly suppressed the OVA-induced airway hyper-responsiveness. It also resulted in a significant alleviation of the infiltration of inflammatory cells into the bronchoalveolar lavage. Additionally, lutein attenuated the increased expression of Th2 responses in OVA-challenged mice. These results demonstrate that lutein is a potent inhibitor that reduces Th2 immune responses. Furthermore, they show that the immunopharmacological function is mediated by a pathway that involves and is regulated by Th2 immune response.

1960~1980년대 제주도 관광이미지에 대한 서설적 연구

송준영(Jun-Young Song) 제주학회 2022 濟州島硏究 Vol.58 No.-

본 논문은 1960년대부터 1980대까지 발행된 관광 사진첩과 제주도 관광 안내 책자에나타난 시각 이미지에 대한 분석을 목적으로 한다. 이를 통해 제주도에 대한 시각적전형성이 만들어져 가는 과정을 살펴본다. 본 논문에서 제시한 시기는 제주도 경제와문화가 변곡점을 맞이하였는데, 정부의 주도로 제주도를 이른바 ‘동양의 하와이’라고할 만한 매력적인 관광지로 만들기 위한 관광정책이 전개되었다. 해당 시기에 제작된 관광 이미지는 제주도를 이국적인 장소로 만드는 데 성공하였다. 하지만, 제주도 관광 사진의 가장 두드러진 점은 같은 소재를 끊임없이 반복하여 사용한다는 점이다. 이러한 이미지들은 비교적 최근까지 제주도를 설명하는 데에 있어서적극적으로 사용하면서 제주도 이미지의 전형성을 형성하였다. 최종적으로 이 연구는 제주도의 관광 안내 책자와 관광 사진첩에 실린 제주도의정형화된 관광 이미지를 시기적으로 나눠 분석함으로써 관광산업이 변화함에 따라제주도에 대한 시각이 어떻게 나타나는지 드러낼 것이다. 관광을 위한 시각 자료를 넘어이미지 상호 교환의 가능성이 있는 장으로서 그 의미를 그려내는 데 목적이 있다. lbums and Jeju-do’s tourist brochures issued from 1960s to 1980s. It, therefore, examines how the visual typicality of Jeju-do has been created. The period suggested by this study was an inflection point in which the economy and culture of it were changed and the government-led tourist policy for transforming Jeju-do into a destination which is attractive enough to be called the ‘Oriental Hawaii’ was developed. The tourist image produced in the period was successful in promoting Jeju-do as an exotic island. The most prominent characteristics of such tourist photos, however, is that they continuously and repeatedly use the same material. Such images have formed the typicality of Jeju-do, as they have been actively used until a recent time in explaining Jeju-do. In conclusion, it would show how Jeju-do is visually perceived, as the tourist industry is changed, by analyzing the stereotyped tourist images of Jeju-do by each period, which are printed in Jeju-do’s tourist brochures and tourist photo albums. It aims to describe them as a field in which images can be exchanged, beyond visual materials for tourism.
