Pervasive enhancement and required enforcement of the Internet of Things (IoTs) in a distributed massively multiplayer online architecture have effected in massive growth of Big-Data in terms of server over-load. There have been some previous works to overcome the overloading of server works. However, there are lack of considered methods, which is commonly applicable. Therefore, we propose a combing Sparse Auto-Encoder and Load-Balancing, which is ProGReGA for Big-Data of server loads. In the process of Sparse Auto-Encoder, when it comes to selection of the feature-pattern, the less relevant feature-pattern could be eliminated from Big-Data. In relation to Load-Balancing, the alleviated degradation of ProGReGA can take advantage of the less redundant feature-pattern. That means the most relevant of Big-Data representation can work. In the performance evaluation, we can find that the proposed method have become more approachable and stable.

This study examines the visitors'evaluations of tourism resources in Insa-dong, which the Seoul metropolitan government has improved recently. This study adopted the method of Importance-Performance Analysis by collecting data through questionnaires. A random sampling of visitors to Insa-dong was conducted in June and July,2001. The survey included questions on the physical and psychological components of Insa-dong's tourism resources. In the case of physical components, eight factors(ancient arts shop, art gallery, atelier, calligraphy shop, pottery arts, traditional tea house, antique shop, traditional clothes) out of thirteen were categorized as 'keeping up the good work'. None of the Physical components was shown as 'low priority'or'possible overkill'. In particular, four factors(restaurant, heritage, Korean-style house and alley, traditional cultural festival) need to be impoved most urgently in terms of visitors'satisfaction. Survey results realize them as high priority in importance but low in performance, thereby designated as, 'concentrate here'. An image of the 'street' showed to be high in importance and identical in performance, so can be categorized between'keeping up the good work'and 'concentrate here'. The results show that unusual outdoor spaces and the festivals of Insa-dong have a significant meaning to the visitors. In the case of psychological components, three factors(general atmosphere experience of unusual atmosphere, appropriateness of stroll time) out of seventeen were categorized as 'keeping up the good work'. Ore factor (shopping) was designated as 'low priority'and not found to be 'possible overkill'. Thirteen factors (various events, possibility of various activity, various flood, richness of play, new experience, education cultural inheritance, parking facilities, resting places, green spaces, meeting places, guide map and information, cleanliness of facilities/convenience) need to be improved mast urgently in terms of visitors' fulfillment. They are perceived as areas of 'concentrate here'. This confirms that attractive events are essential for the recent visitor satisfaction. Furthermore, visitors are not satisfied with its amenity and acccss in Insa-dong despite the improvements. In conclusion, positive impressions, both physical and psychological, should be maintained while factors mentioned to be lacking should be prioritized in order of necessity to improve the image of Insa-dong and solutions need to be found and implemented. The results of this study would be helpful in the planning and management of nsa-dong considering the visitors'requirements.

With the evolution of wireless sensor network (WSN) technology, the routing policy has foremost importance in the Internet of Things (IoT). A systematic routing policy is one of the primary mechanics to make certain the precise and robust transmission of wireless sensor networks in an energy-efficient manner. In an IoT environment, WSN is utilized for controlling services concerning data like, data gathering, sensing and transmission. With the advantages of IoT potentialities, the traditional routing in a WSN are augmented with decision-making in an energy efficient manner to concur finer optimization. In this paper, we study how to combine IoT-based deep learning classifier with routing called, Kriging Regressive Deep Belief Neural Learning (KR-DBNL) to propose an efficient data packet routing to cope with scalability issues and therefore ensure robust data packet transmission. The KR-DBNL method includes four layers, namely input layer, two hidden layers and one output layer for performing data transmission between source and destination sensor node. Initially, the KR-DBNL method acquires the patient data from different location. Followed by which, the input layer transmits sensor nodes to first hidden layer where analysis of energy consumption, bandwidth consumption and light intensity are made using kriging regression function to perform classification. According to classified results, sensor nodes are classified into higher performance and lower performance sensor nodes. The higher performance sensor nodes are then transmitted to second hidden layer. Here high performance sensor nodes neighbouring sensor with higher signal strength and frequency are selected and sent to the output layer where the actual data packet transmission is performed. Experimental evaluation is carried out on factors such as energy consumption, packet delivery ratio, packet loss rate and end-to-end delay with respect to number of patient data packets and sensor nodes.

Purpose: The purpose of this study was to figure out how PAP (Post-Activation Potentiation) phenomenon affects short-term performance efficiently. Methods: This study was conducted with 18 Taekwondo athletes and 16 healthy adults. By using isokinetic dynamometer, two different intervention, TDP (Top-down program) and BUP (Bottom-up program), were performed to measure isokinetic parameter; (peak torque: PT, total work: TW, average power: AP, and average torque: AT) of knee extensor for intragroup, intergroup comparison and two-way ANOVA. Results: The Taekwondo athletes group showed statistically significant differences in all isokinetic parameters PT, TW, AP, and AT after TDP (p<0.05). However, in the healthy adult group, the difference in isokinetic parameters according to the exercise sequence was not statistically significant. (p>0.05). PT and TW at TDP were statistically significant (p<0.05) when the rate of change in TDP and BUP was compared and analyzed considering the difference in physical ability between the Taekwondo athlete group and the healthy adult group. However, AP and AT were not statistically significant. Finally, when examining the interaction between the two groups and two exercise sequence according to isokinetic parameters, only TW (p<0.05) showed a statistically significant interaction, while PT (P=0.099), AP (P=0.103), and AT (P=0.096) did not. This study suggests that short-term performance can be improved through the PAP phenomenon when TDP is applied to the Taekwondo group. Conclusion: According to our result, for Taekwondo athletes, if the goal is to improve short-term performance just before the main game, we suggest a training program through TDP.

본고는 한국과 중국 전통 언어유희 가운데 하나인 재담(才談)과 상성(相聲)의 역사적 변천과 현재적 의의에 대해 살펴본 글이다. 한국의 재담과 중국 상성은 모두 웃음을 주기 위한 대표적인 언어유희이며 전통적인 공연예술이다. 재담과 상성의 기원은 우희(優戱)로 거슬러 올라갈 수 있다. 우희는 가장 전통적인 언어유희이며 우희를 전승하는 과정에서 여러 가지 공연물이 파생되었다. 그 중에서 한국 재담과 중국의 상성은 비교적 우희의 전통을 잘 이어간 공연물이라고 할 수 있다. 18세기 후반부터 한국 재담은 독립적인 공연물로써 자리를 잡았고 그 뒤로 박춘재 등 전문적인 재담 연희자들이 활발하게 활동하며 공연하였다. 20세기 초 유성기 음반을 취입하면서 재담은 주로 극장 무대와 라디오에 출연하게 되었다. 이때 재담에서 새로운 공연물인 만담이 파생되었는데 만담은 재담보다 시사를 풍자하고 세태를 비판하는 데에 중점을 두었다. 만담은 한참 동안 인기를 끌었다가 21세기에 들어와서 완전히 소멸되었다. 현재까지 한국에 전승하고 있는 재담은 가면극 같은 전통연희에만 남아 있다. 한편 한국 재담보다 조금 늦은 시기인 19세기 중후반에 구축된 중국 상성은 처음에는 천민의 비속한 기예로 여겨졌으나 20세기 초에 인기가 많아지면서 드디어 공연예술로써 무대에 오르게 되었다. 20세기 중반 상성은 개혁을 통해서 사회를 칭송하고 교과하는 내용이 주로 다루는 신상성이 형성되었으나, 신상성에는 세태를 풍자하고 해학적인 내용이 축소되어 재미가 없어졌으므로 얼마 후 인기를 잃었다. 21세기 초 상성은 만담과 똑같이 소멸될 지경에 처했지만 전통을 부흥시키려는 젊은 상성 배우들의 노력을 통해 '전통'과 '소극장'으로 회귀하자는 또 한 번의 상성 개혁이 일어났다. 전통으로 돌아온 현재의 '전통 상성'은 다시 중국 관중들의 애호와 성원을 받고 있다. 한국 재담과 중국 상성은 역사와 연행양상 면에서 비슷한 점이 많지만 현재 서로 다른 운명에 처해 있다. 두 공연물의 내용이나 형식 측면에서 공통점도 상당히 많이 발견된다. 중국 상성의 경우 전통 곡예 장르 가운데 하나로 현재까지도 중국 사람들의 사랑을 받고 있으며 중요한 전통 공연물 가운데 하나로 자리 잡고 있다. 반면, 한국에서는 독립적인 공연예술로써의 재담이 소멸되어 가고 이제는 가면극 같은 전통연희에만 재담의 모습을 엿볼 수 있다. 한국 재담과 중국 상성은 전승과정에서 유사한 변화를 겪었다는 사실, 그리고 한국 재담이 사라진 반면 중국 상성은 잘 보존되고 전승되어 있는 이유를 본고를 통해 확인할 수 있다.

The purpose of this study was to investigate the effects of different types of exercise training on neurodegeneration and cognitive function in mice with impaired glucose tolerance (IGT). Thirty-six male C57BL/6 mice were randomly assigned to the control (CO, n = 9) and impaired glucose tolerance (IGT, n = 27) groups. The IGT group consumed 45% high fat diet for 4 weeks and received 40 mg/kg of streptozotocin twice in the lower abdomen to induce IGT. After the IGT induction period, the IGT group was subdivided into IGT + sedentary (IGT, n = 9), IGT + endurance exercise (IGTE, n = 9), and IGT + resistance exercise (IGTR, n = 9). The IGTE and IGTR groups performed treadmill and ladder climbing exercises 5 times per week for 8 weeks, respectively. Fasting glucose and glycated hemoglobin (HbA1c) levels were significantly higher in IGT group than in CO, IGTE, and IGTR groups (p < 0.05). HOMA-IR was significantly higher in IGT group than CO group (p < 0.05). Hippocampal catalase (CAT) was significantly lower in IGT group than in CO group (p < 0.05), while beta-amyloid ($A{\beta}$) was significantly higher in IGT group than in CO group (p < 0.05). Hippocampal tau was significantly higher in IGT group than in CO, IGTE, and IGTR groups (p < 0.05). The Y-maze test performance for cognitive function was significantly lower in IGT group than in CO, IGTE, and IGTR groups (p <0.05). These results suggest that IGT induces neurodegeneration and negatively affects cognitive function, while regular exercise may be effective in alleviating neurodegeneration and cognitive decline regardless of exercise type.

This study examines the stage costumes of the creative musical 'Hyecho', which was performed six times in the Chung Ang Art Center hosted by Chung-Ang University's performance & media agency from December 20 to 22 in 2006. The stage costumes were made based on these basic design elements of stage costumes that were dyed : line, silhouette, material, and color. First, the creative musical 'Hyecho' presents a new form of fusion theatre, which blends Korean traditional music and dance with videos. Thereby, the musical has opened a new phase in Korea's creative performing arts. Second, in musical performances that combines dance and songs, stage costumes should be made not only to attract the audience's eyes, but also not to interrupt actors' vocalizations and movements by taking their physical features into account. Also, costumes should be made in consideration of their relationships with visual elements, including stage settings and lighting. Third, the musical features fusion-style stage costumes, which combines Hanbok, the Korean traditional costume, and Indian traditional costumes with modern costumes. For the line and silhouette, costumes show the beauty of curves through the curves of Hanbok and India's traditional costumes and also through irregular pleats of pants. Also, by using cotton materials, which is easy to dye and not readily deformed, costumes feature colors that are found in nature through a gradation dyeing technique. In doing so, it offers visual amusement to the audience by making stage costumes look like a beautiful painting. Fourth, the stage costumes of the chorus feature costumes that use lining and pleated skirts using belts, and various accessories, including necklaces that use strings in order to express evil spirits. Since there is not much time to change costumes during a performance, using such items are helpful to show the unique characteristics of actors effectively during the limited time. Also, coordinating with the lighting director allows the costume designer to make better costumes for the chorus and make the performance more dramatic. Finally, it was not necessary to wash the costumes of the chorus of the fusion musical Hyecho 2006 since it was performed only six times. However, when using dyed costumes for the long-term performance, it might cause problems such as bleaching that result from the washing of costumes and low durability that can result in the deformation of costumes. As performing arts are made in various forms and are diversified, it is needed for stage costumes to change accordingly through new attempts and various ways of expression.
