이 논문은 한국과 몽골의 산속을 ‘기자속’, ‘산전속’, ‘산후속’으로 구분해서 공통점과 차이점을 살펴본 것이다. 출산의례라고도 하는 산속은 오래 전부터 민족마다 자신들의 선조로부터 전해 내려온 출산과 관련된 의례를 담고 있는 습속이다. 각 나라 전통 사회는 그 사회의 민족적 특질, 민족성, 사회 구조, 사상 등을 반영하게 되고 있는 것으로 볼 수 있다. 한국과 몽골의 산속에 나타나는 특징은 차이를 통해 찾아 볼 수 있다. 한국의 출생의례는 절 ,지성과 같은 기자속은 물론이고, 산전속의 핵심적인 부분으로 태몽에 대한 내용이 많다. 반면에 몽골의 출생의례는 산전속에서는 임산부들이 가지는 음식과 행위와 관련된 금기어가 많으며 태어난 아이에게 이름을 지어주는 내용이 많은 편이다. 한국과 몽골은 아들을 얻으려고 하는 순수한 마음은 비슷하다. 산후속은 한국에서 아들과 딸의 상징을 구별하여 표시했는데 몽골에서 아들과 딸을 구별하지 않고 표시했다는 점이다. 육아속은 양국에서 아이를 위해 여러 행사를 중심으로 하는데 행사를 치를 때 가국의 특별한 예물이 다르고 있는 것을 볼 수 있다. 그리고 한국의 경우 육아속은 백일날 배냇머리를 자르는 의식과 출생 후 일주년을 기념하는 돌날 까지를 말한다. 이에 비해 몽골의 육아속은 출생 후 3년 후에 비로소 배냇머리를 자르는 의례를 행하기 때문에 한국에 비해 길다. 한국의 출생의례를 보면 역신을 속이기 위하여 천한 이름으로 아명을 지어주는데, 몽골의 경우도 이와 유사하게 역신을 기만하고 속여서 역신으로부터 어린 아이를 보호하기 위하여 동식물의 이름이나 혐오스럽고 이상한 이름을 지어주기도 한다. 이러한 행위는 어린 아이가 사회의 한 구성원으로 통합하기 위하여 거쳐야만 하는 통과의례의 전이 단계인데 한국과 몽골의 출생의례에서 공통적인 민속이라고 할 수 있다. 이 논문을 통해 한국과 몽골의 산속을 비교하면서 양국의 전통문화를 점검하고 한국과 몽골의 민속 문화만이 지닐 수 있는 상호간의 문화적 친영성을 확인할 수 있었다. The study analyzes common and different points of Sansok in Korea and Mongolia by classifying it into Gijasok, Sanjeonsok and Sanhusok. From the past, Sansok is a tradition that contains ancestral ritual on the lifestyle and belief of each nation. It is confirmed that Sansok in Korea and Mongolia reflected national characteristics, national identity, social structure and idea. The birth ritual in Korea has many contents on dream of the forthcoming conception of a baby as a key of Sanjeonsok as well as Gijasok like Chiseong. To the contrary, it was Sanjeonsok in Mongolia that has many taboos related to foods and behaviors of pregnant women. Both Korea and Mongolia are Gijasok having a notion of preferring a son to a daughter. As Sanhusok, in Korea the symbols of boy and girl were separated, but in Mongolia, it was not identified. Yukasok focuses on various events for children in both countries and the presents for event were different. In the birth ritual in Korea, child name was used to be devised in a humble name to protect child from Yeoksin. It was similar at Mongolia and they used to name the child in the name of animal or plant in a bizarre or horrible term. This study could find the affinity of both cultures by comparing culture of Sansok in Korea and Mongolia.

Over the years, the applications of indocyanine green (ICG) fluorescence have increased exponentially. Recently, it was introduced in parathyroid surgery. We describe a case in which a parathyroid adenoma in the upper posterior mediastinum was resected by means of ICG-guided video-assisted thoracoscopic surgery. ICG helped in intra-operative localization and demarcation of the adenoma facilitating in toto resection, thereby successfully treating primary hyperparathyroidism.
A high-throughput microfluidic assay to study neurite response to growth factor gradients

<P>Studying neurite guidance by diffusible or substrate bound gradients is challenging with current techniques. In this study, we present the design, fabrication and utility of a microfluidic device to study neurite guidance under chemogradients. Experimental and computational studies demonstrated the establishment of a steep gradient of guidance cue within 30 min and stable for up to 48 h. The gradient was found to be insensitive to external perturbations such as media change and movement of device. The effects of netrin-1 (0.1–10 µg mL<SUP>−1</SUP>) and brain pulp (0.1 µL mL<SUP>−1</SUP>) were evaluated for their chemoattractive potential on neurite turning, while slit-2 (62.5 or 250 ng mL<SUP>−1</SUP>) was studied for its chemorepellant properties. Hippocampal or dorsal root ganglion (DRG) neurons were seeded into a micro-channel and packed onto the surface of a 3D collagen gel. Neurites grew into the matrix in three dimensions, and a gradient of guidance cue was created orthogonal to the direction of neurite growth to impact guidance. The average turning angle of each neurite was measured and averaged across multiple devices cultured under similar conditions to quantify the effect of guidance cue gradient. Significant positive turning towards gradient was measured in the presence of brain pulp and netrin-1 (1 µg mL<SUP>−1</SUP>), relative to control cultures which received no external guidance cue (<I>p</I> < 0.001). Netrin-1 released from transfected fibroblasts had the most positive turning effect of all the chemoattractive cues tested (<I>p</I> < 0.001). Slit-2 exhibited strong chemorepellant characteristics on both hippocampal and DRG neurite guidance at 250 ng mL<SUP>−1</SUP> concentration. Slit-2 also showed similar behavior on DRG neuron invasion into 3D collagen gel (<I>p</I> < 0.01 relative to control cultures). Taken together, the results suggest the utility of this microfluidic device to generate stable chemogradients for studying neurobiology, cell migration and proliferation, matrix remodeling and co-cultures with other cell lines, with potential applications in cancer biology, tissue engineering and regenerative medicine.</P> <P>Graphic Abstract</P><P>We describe a three-channel microfluidic device to study the role of chemogradients on neurite outgrowth and guidance in 3D scaffolds, using experimental and computational studies. The stable chemogradients in these devices could also be used to screen potential drugs for neuron pathway regeneration under disease/ injury conditions, cell migration and cell–cell interactions. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c0lc00240b'> </P>
HOMOCLINIC ORBITS IN TRANSITIONAL PLANE COUETTE FLOW
Lustro, Julius Rhoan T.,Kawahara, Genta,van Veen, Lennaert,Shimizu, Masaki Korea Society of Computational Fluids Engineering 2015 한국전산유체공학회지 Vol.20 No.4
Recent studies on wall-bounded shear flow have emphasized the significance of the stable manifold of simple nonlinear invariant solutions to the Navier-Stokes equation in the formation of the boundary between the laminar and turbulent regions in state space. In this paper we present newly discovered homoclinic orbits of the Kawahara and Kida(2001) periodic solution in plane Couette flow. We show that as the Reynolds number decreases a pair of homoclinic orbits move closer to each other until they disappear to exhibit homoclinic tangency.
Homoclinic Orbits in Minimal Plane Couette Flow

In wall-bounded shear flow recent studies have pointed the significance of the stable manifold of nonlinear simple invariant solutions, referred to as edge states, to the Navier-Stokes equation in the formation of the laminar-turbulent boundary. Here we present homoclinic orbits of the periodic edge state found by Kawahara and Kida[1] in plane Couette flow. It is observed that these homoclinic orbits collide and disappear to exhibit homoclinic tangency as the Reynolds number decreases.
