In this study, the correlation between the damage type and operating conditions of the sleepers was analyzed based on the design data and visual inspection results for the concrete sleepers of the sleeper floating track (STEDEF) that have been in operation for more than 20 years. It appeared in the form of cracks, breakages, and breaks in the concrete at the center and tie bar contact and buried areas. As a result of the numerical analysis, it was analyzed that the change in the left and right spring stiffness of the sleeper resilience pad increases the maximum stress, tensile stress, compressive stress, and displacement of the concrete sleeper, and stress concentration in the concrete at the tie bar contact area. It was proved analytically that the sleeper resilience pad can affect the damage of the concrete sleeper. Therefore, damage of concrete sleepers in the sleeper floating track in urban transit could be caused by changes in spring stiffness of sleeper resilience pads. It was reviewed that preventive maintenance such as improvement and timely replacement of sleeper resilience pads was necessary.

This study proposes a process to design and analyze stage costumes by design elements for the costumes of the Korean traditional music cantata 'I Will Rise'. This study states fundamental references to make costumes of similar performances in the future and develop costume designs based on the format of a play. The findings are as follows. First, the costume production process of 'I Will Rise' is conducted in the order of directing intentions and script analysis, costume design, miniature production, costume production, costume modification, run, and post-production. Second, an overall Korean silhouette is expressed through the creation of costumes based on the construction of Korean traditional clothing (hanbok); however, from a detail perspective, a modernistic sensitivity is expressed through the use of modern elements (wing shoulders attached to shoulders, narrow ribbons made in a string form, and wristlets and belts) not found in hanboks. Third, tie-dying is applied to the costume colors of each character to highlight the traditional and unique feeling of dye and symbolic colors that effectively represent each role used to communicate the storyline and character emotions to the audience. Fourth, materials for costumes are cotton and linen (frequently used to create the texture of a Hanbok) as the costume of each character is emphasized to the use of additional and detailed materials such as artificial leather, hemp, and silk.

An educational practice is a communicational course between educator and student with scheme and execution of studying. The communicational contents of the practical course require teaching transmission and recipient process for educator and student as a major knowledges end techniques in order to achieve student's aim. The communication of practical course consists of educators, students, and practical contents, and they also form both meaning objects and mutual relationships for constitution of the practical courses. In order to develop the effective plan for practical process, we have to understand the phenomena of meaning operations which consists in connections of the practical exercise and the meaning object. This study is to approach a phenomenal analysis as respects the meaning operations how forms of tie meaning object exert in the practical course. On the basis of this analysis, we grasp properties of the practical course into the meaning object, and in these connections, suggest the category of cognizance to put execution in the practical course by interpreting factors of the meaning operations.

In recent years, questions have arisen under several forms with respect to the need for adapting present legal order established under the Chicago Convention and relevant customary rules into newly developed environment surrounding the international air transport industry. Major feature of such trends included in opinions for modification of the present legal order might be defined as more liberalistic approach to this industry. In this respect, many scholars and lawyers in this field agree with a view that a theoretical tie between an aircraft/air liners and a register - State lies in political and strategical concern of the State so that each aircraft/air liners has been attributed a single nationality. In the context of such concern, each aircraft/air liners has been related with each register-State in the form of "genuine connection". However, present and near future development of air transport industry and its world - wide market requires some modification of such single nationality regime. Taking into account such circumstances, States as creator of present legal order are in the process of establishing new legal order where air liners with multi - nationality are capable of satisfying to such needs. As adopting a series of liberalization package for air transport industry in european continent, European Union adopts a concept of "community air carrier", by which an air space of each member State is open to each other, especially through the grant of cabotage right. A serious concern may arise in such grant because the Article 7 of the Chicago Convention prohibits such grant on an exclusive basis. While many theoretical opinions have been put forward concerning the interpretation of that article, a case of European Union shall be a good test of the range of its application. It is anticipated that future development around this issue shaH furnish us a major feature of the liberalization of international air transportation and an adaptation process of present legal order.

VR movies form a relationship with the audience in completely different ways from general movies with their screen. In VR movies, the audience becomes the camera and also the subject of the camera viewpoint, which raises a need for a frame theory unique to VR movies to examine the first person viewpoint and replace the edition of frames to deliver a narrative. In VR movies, the frames delivering a narrative are not revealed and perform the symbolic narrative function, thus being called "implicit frames." The study discussed their related theoretical backgrounds including Russian Ark made in the one shot, one cut method by Alexander Sokurov, off-screen elements, and the Fourth Wall. In VR movies, the audience gets immersed in the narrative based on their paradoxical dilemma, which means that they exist in reality but are absent on screen at the same time, and experiences hyper-reality. In VR movies, space has a couple of attributes including the blocking of eyeline to move it and telepresence to tie up presence between reality and virtuality.

The addition of switches to a distribution feeder does, in general, increase reliability by decreasing the duration of the outage of many to the customers on the feeder. To cover its service area so that feeder-level delivery reaches sufficiently close to all customers, feeders typically split their routes many times, in what is often called a lateral feeder. It is interesting to note, however, that the effectiveness of a switch is very much dependent on the types of lateral feeder. The types of lateral are classified into two types. The first is loop lateral feeder that can connect its load to an adjacent feeder through a tie line in case that a fault occurs in its feeder and it is laid out so that every feeder has complete fault backup through re-switching of its loads to other sources like a main feeder The second is the radial lateral feeder cannot connect its load to an adjacent line, no provision is made for contingency backup of feeders. There are no other circuits in the radial lateral feeder form which to restore power. In this study, we evaluate the effectiveness of a switch installation between on the radial and loop lateral feeders to increase reliability by decreasing the duration of the outage. These results can help power utility to design the switch layouts on the radial and loop lateral feeder system.

The purpose of this research therefore, was to conduct research on the actual state of manufacturers of cycle wears and the condition in wearing; to present the basic data to develop cycle wears which can lessen the trouble for the human body and an excellent feeling in wearing. For research on the actual state of manufacturers of cycle wears, three domestic companies were grasped. To inquire the condition in wearing, the method of questionnaire was used for 100 peoples consisted of male cycling professional players and ordinary peoples with the same tastes. As the result of research: The manufacturers were targeting for the professional players and men with the same tastes. They produced goods by themselves as well as in the form of subcontract, and they did not classify goods for male & female. Materials they used for cycle wears were mainly composed of jersey with spandex and nylon. The production ratio of cycle wears is shown as 80% for company A, 25% for company B, and 90% for company C. They make a pattern of cycle wears by a technical tie-up with foreign companies, or by the development of their own pattern. As the result of study on the present condition in wearing cycle wears according to each season, it was figured out that the users usually weard short-sleeved T-shirts with dividing zipper for summer upper garment, shorts most preferably for summer lower garment; long-sleeved shirts for spring and fall upper garment, and shorts with incision most preferably for spring and fall lower garment. Also, they usually weard jumpers with incision for winter upper garment, and long pants in which ankle parts of incision were tightened most preferably for winter lower garment.

Background: Small-cell lung cancer (also known as SCLC) is an aggressive form and untreated patients generally die within about 3 months. To obtain further insight into mechanism underlying malignancy with this cancer, an miRNA synergistic regulatory network was constructed and analyzed in the present study. Method: A miRNA microarray dataset was downloaded from the NCBI GEO database (GSE27435). A total of 546 miRNAs were identified to be expressed in SCLC cells. Then a miRNA synergistic network was constructed, and the included miRNAs mapped to the network. Topology analysis was also performed to analyze the properties of the synergistic network. Consequently, we could identified constitutive modules. Further, common target genes of each module were identified with CFinder. Finally, enrichment analysis was performed for target genes. Results: In this study, a miRNA synergistic network with 464 miRNAs and 2981 edges was constructed. According to the topology analysis, the topological properties between the networks constructed by LC related miRNAs and LC unrelated miRNAs were significantly different. Moreover, a module cilque0 could be identified in our network using CFinder. The module included three miRNAs (hsa-let-7c, hsa-let-7b and hsa-let-7d). In addition, several genes were found which were predicted to be common targets of cilque0. The enrichment analysis demonstrated that these target genes were enriched in MAPK signaling pathways. Conclusions: Although limitations exist in the current data, the results uncovered here are important for understanding the key roles of miRNAs in SCLC. However, further validation is required since our results were based on microarray data derived from a small sample size.

System In Package (SiP) is getting popular and momentum for the recent wearable, IoT and connectivity application apart from mobile phone. This is driven by market demands of cost competitive, lighter and smaller/thinner and higher performance. As one of many semiconducting assembly products, Leadframe product has been widely used for low cost solution, light/ small and thin form factor. But It has not been applied for SiP although Leadframe product has many advantages in cost, size and reliability performance. SiP is mostly based on laminate substrate and technically difficult on Leadframe substrate because of a limitation in SMT performance. In this paper, Leadframe based SiP product has been evaluated about key technical challenges in SMT performance and electrical shield technology. Mostly Leadframe is considered not available to apply EMI shield because of tie-bar around package edge. In order to overcome two major challenges, connection bars were deployed properly for SMT pad to pad and additional back-side etching was implemented after molding process to achieve electrical isolation from outer shield coating. This product was confirmed assembly workability as well as reliability.

This study examines the types and characteristics of women's garments excavated in the early Joseon Dynasty before 1592. The study sorts out headgear, jacket, skirt and trousers, and coats from the historical texts in the early Joseon Dynasty and excavated women's wears in the fifteenth and sixteenth centuries, and analyzes their textiles and patterns. The Joseon women's garments convey several features. They are wide across the chest and square shaped collar with virtually straight sleeves. While their breast-ties are extremely little for the size of clothes, they do not have any inner-tie. They have broad and short dongjeongs which seem to be hard to be adjusted. There are a variety of headgear. Jang-Jeogori slit down in both sides. The Jeogori after the seventeenth century transformed a more practical form of a fitting dress to an individual body in comparison with the sixteenth jeogori. It is identified that the fabrics in the early Joseon period were woven more diversely and colorfully than the late Joseon period. Most of the excavated fabrics in the sixteenth century were in silk. Materials for adornments before 1592 were not much diverse and their designs mostly contained patterns of lotus flowers, patterns of cloud and treasures with oblique lines. The colors are mainly brown, navy and green. The Joseon women's clothes were comprised of skirts with folded hem, coat with round collars, wide leg pants, Jangot, long-sleeved coat with folding collars, and quadrangular pieces of cloth in various sizes, or mu and so forth. Joseon women's clothes, like men's wears, partake of active functions in their headgears, wide leg pants, styles in short front and long back, and coat with round collars.
