'Reboot' and 'Homage' are using as creative techniques in traditional storytelling media fields such as movies or dramas, but the possibility of expanding the transmedia story world has not yet been presented. This study was written to present a new concept of transmedia story world expansion type using the 'Reboot' and 'Homage' methods. 'Reboot' and 'Homage' are typical storytelling methods of K-POP idol groups that need to develop content. I selected , , and , which have built their story world, and examined both the narrative creation section and the marketing application section. The result of the study is as follows. First, EXO is an example of a reboot case. They set the original set as 'past' and insert the new storylines. Second, BTS is an example of a character's reboot. They built a story world by paralleling 'Idol BTS' and 'Character BTS'. Third, Wanna One is an example of the original story world's homage. They reorganize the story world of and attracting the attention of the existing audience. Fourth, BTS is an example of other media homage which reinterprets the meaning of BTS characters and story world by using the meaning of classic works.

The authors carried out an experiment to investigate the responsive behavior of sea eel, Astroconger myriaster(BREVOORT) to chemical stimuli. The experimental tank was made in doughnut type by using FRP plates. The channel of tank was divided into three concentric troughs by using perforated plastic plates. The inside trough was used as influent part, the outside one as effluent part, and the middle one as the testing trough in which testing fish may be swimmable. The influent part was radially portioned into 12 sections so as to be 30 degrees of central angle. But a basin of any section in testing trough was diverged in the range of 45 degrees of central angle. The the testing trough are radially divided into eight zones. Water is supplied at the rate of 6.3l per minute from the central water tank set as high as 50cm in the center of doughnut, passed across the influent part, testing trough, effluent part and finally discharged by overflow pipes. The chemical substance to stimulate the sea eel was extracted from mackerel, shad and krill which are used as bait for fishing. The chemical substance was injected into any one of 12 hoses which supplies water from central water tank to the influent part at the rate of 2ml per minute. Sea eels used for the experiment were caught by pot in the coast of Chung-mu and accustomed to the tanks for 5 days before applying them to the experiment. The result obtained are as follows: 1. The rate of time length of sea eel's staying in the stimulated zone, as the extracts of mackerel, shad and krill were given to it, was observed as 7.9%, 30.9% and 11.4% respectively. It means that the extract from shad was the most effective of three in attracting sea eel. 2. To compare the effect of freshness of bait fish, the extracts were prepared from shad just killed, form the 24 hour-lapsed one and from the 48 hour-lasped one after killed. The rate of time length of sea eel's staying in the stimulated zone was 30.9%, 17.1% and 11.3% respectively. It means that the freshness is much effective in attracting olfactory fishes like sea eel.

Flying behavior during nighttime and control methods of fruit sucking pests were investigated in yuzu (Citrus junos) groves at Koheung area from August to November in 1999. Among the 3 kind of bulbs with different color (white, blue and yellow), white bulb attracted the most number of fruit sucking pests . The 93 percent of the moths was attracted from sunset to 24 o\`clock. Main flying time of hemipteriods in early, mid, and late October were from 22 to 04 o\`clock, sunset to 02 o\`clock and sunset to 24 o\`clock, respectively. Their flying time become earlier as the night temperature declines. For control of fruit sucking pests, attraction liquid traps, light traps (100 W) and illumination light bulb were set up in the yuzu groves (1,000 $\m^2$) from the 1 st October to the 3rd November. Attraction liquid was composed of a raw rice wine 2,000 ml+black sugar 100 g+vinegar 100 ml. When established at 3 sites per 1,000 $\m^2$ orchard, attraction liquid trap reduced the number of sucking spots on yuzu fruit to 64% and its attracting effect maintained for 3 weeks after setting-up. Three light traps per 1,000 m2 which turned on from sunset to 02 o\`clock reduced the number of sucking spots by 60% .

As animation emerged as a high value-added content business, more studies are conducted focusing on the fact that the key to the success of animation is not a story but a character. This study aims to examine the characters of , the globally loved animation, and figure out its interactive way of attracting viewers based on Spectatorship Theory, so that it can help set the nation's TV animation series to be made on the right track. To achieve this goal, it will explore various aspects including the concept of animation character, the relations between ideology and character, and the changes in design according to a social phenomenon, then based on Spectatorship Theory will analyze and suggest how the characters of fulfill the required conditions to attract viewers. In addition, it will examine the wide application of the characters of . In conclusion, unlike theatrical animation, TV animation has a characteristic that it can easily and repeatedly deliver messages to viewers over a long time, however, domestic TV animation turned out to fail to utilize the advantage. In other words, while its character has distinct individuality, it is not supported by creative and solid story line, and the character is not attractive as much as the characters of which successfully evoke sympathy from viewers. In animation, arousing sympathy from its viewers or audiences is very important, so a character that well reflects social discourse is an integral part of it. Therefore, in-depth and specialized study on animation's character is highly required for the sustainable success and growth of domestic animation.

From the four tuna purse seiners operating in the western equatorial Pacific waters 370 tuna schools were sampled on attribute of the school, fishing operation of purse seine sit and catch. The data were tabulated and subjected to the statistical tests of independency on the associated object and availability of the school, and catch per set of purse seine fishery as well. The resultant inferences are as follows. 1. Most frequent attributes of the tuna schools found on the surface are associated with sea birds, bait fishes and the flotsams. 2. In fishing operations of purse seine sets on the flotsam-associated schools, the settings were more frequently performed at dawn than in day-time. In fishing operations on the sea-birds-associated schools, the siftings were more frequent in day-time than at dawn. 3. From the flotsam-associated schools the successful sets were significantly more frequent. 4. In the fishing operations of purse seine sets, some of the flotsam-associated schools were subjected to the supplementary sets in success to the initial sets until the schools were consummated. 5. The fish-attracting effect of the flotsam is correlated with structure of the flotsam, but not with length of the flotsam. The flotsams, which tend to attract large tuna schools are the complicated-structure flotsams, i, e. driftwoods with roots or branches or with both of them, otherwise a bunch of uprooted bamboo shrubs, while a log without roots and branches tend to be an attractant inferior to the flotsam of complicated structure.

This paper presents a technology for manipulating external devices by Brain Computer Interface (BCI) system. Recently, BCI based rehabilitation and assistance system for disabled people, such as patient of Spinal Cord Injury (SCI), general paralysis, and so on, is attracting tremendous interest. Especially, electroencephalogram (EEG) signal is used to organize the BCI system by analyzing the signals, such as evoked potential. The general findings of neurophysiology support an availability of the EEG-based BCI system. We concentrate on the event-related synchronization of motor imagery EEG signal, which have an affinity with an intention for moving control of external device. To analyze the brain activity, short-time Fourier transform and particle swarm optimization are used to optimal feature selection from the preprocessed EEG signals. In our experiment, we can verify that the power spectral density correspond to range mu-rhythm(${\mu}8$~12Hz) have maximum amplitude among the raw signals and most of particles are concentrated in the corresponding region. Result shows accuracy of subject left hand 40% and right hand 38%.

Under the influence of ever-globalized world economy, Yangsan Port of Shanghai, a central hub of Chinese economy, was opened up on Dec. 1, 2005 in the expectation of heart of northeast Asian harbor logistics. It has triggered severer competitions among northeast Asian ports. In an effort to keep robust standing as a central port of northeast Asia, Korea has still built additional new ports and opened up 3 docks in Nov. 2005. Amid these changing port environments, it is foremost to take the competitive edges of new ports in advance of major rival ports in the interest of preoccupying the standing of those new ports as the central hub of northeast logistics. According to the developmental strategies of new ports can be summed up as follows: First, it is required to separate port development from marketing as a part of separating developmental entity from management/maintenance entity. Second, it is required to develop dedicated port for feeder vessels along with new ports to save more time and cost spent by shipping companies. Third, the attraction of jumbo shipping companies to port development needs differentiated countermeasures for each shipping company, and those measures should be taken in advance before jumbo shippers decide their own shipping strategies in future. Fourth, in terms of incentives for attracting jumbo shipping companies, it is required to offer the incentives to them in using new ports in connection with Busan ports. Fifth, it is critical to set up a benchmark of competitors(ports) for establishing one-stop automatic administration process system upon developing ports. Finally, it is required to prepare a plan for using rearward lands in connection with ports for more efficient use of development complex behind port.

When fisherman use the boat seine net to catch anchovy, a large noise (drum can, small drum and small gong) is used to scare the anchovy school along the wing nets, and into the bag net were they are caught. We want to know how much of an effect these s:mnds have on forceing the anchovy school towards the bag net. The underwater sounds of ancho\'y, drum can, small drum and small gong were analyzed in the labroatory. The behavioral responeses to the playback sounds of anchovy feeding and sounds of artificial instruments were also investigated. The feeding and artificial sounds of the samples were recorded by a tape recorder through a hydrophone in an anechoic aquarium. The sound intensity level was measured by means of a sound level meter in an anechoic chamber. The frequency and intensity of various sounds were analyzed with an analyzing system consisting of a ~-octave filter set, a high speed level recorder, an amplifier and an oscilloscope. The most successful recording was edited into a 9 to 10 second sound track and was repeated in a sequence of 9 to 10 second intervals. The sequence was then reproduced into an anechoic aquarium through the underwater speaker. The results of investigation are as follows; 1. The frequency of the feeding sound was 63~80Hz, and the pressure level produced was less than 32db. 2. The frequencies of the artificial sounds were 315~ 1,OOOHz, and the pressure levels were 88~95 db in the air. 3. When a hydrophone was placed 70cm below the surface with artificial sounds (drum can, small drum and small gong) produced 1 meter above the surface, the pressure level decreased about 30db. 4. The feeding sound was ineffective in attracting the anchovy, because of interference from ambient noise. 5. The artificial sounds had such a small effect on the anchovy's that they could not be used in ocean fisheries.

The Korean economy has undergone growth based on manufacturing end products. The Korean government aims to advance industry by strengthening the materials and components industry, which is attracting more attention in terms of maintaining the competitiveness of existing key industries, and fostering new industries required in the era of the Fourth Industrial Revolution. Despite this importance, there is insufficient related research on the efficient R&D of the materials and components industry. This study analyzed the R&D efficiency. In addition, exploratory research was conducted on the impact of corporate size and type of cooperation on R&D efficiency. Output variables were set to reflect economic performance and the empirical analysis revealed that overall R&D efficiency is low. Small firms were found to perform better than large firms in terms of firm-size, and the efficiency of business-university-research cooperation is worse than other types of cooperation. This study is exploratory research considering the materials and components industry, and the results provide implications for research institutions and regarding types of cooperation. This is expected to help develop polices for qualitative growth and R&D strategies for investment and allocation.

Recently, as a part of the production of spatial information by smart cities, three-dimensional reproduction of structures for reverse engineering has been attracting attention. In particular, terrestrial LiDAR is mainly used for 3D reproduction of structures, and 3D reproduction research by UAS has been actively conducted. However, both technologies produce blind spots due to the shooting angle. This study deals with vertical structures. 3D model implemented through SfM-based image analysis technology using UAS and reproducibility and effectiveness of 3D models by terrestrial LiDAR-based laser scanning are examined. In addition, two 3D models are merged and reviewed to complement the blind spot. For this purpose, UAS based image is acquired for artificial rock wall, VCP and check point are set through GNSS equipment and total station, and 3D model of structure is reproduced by using SfM based image analysis technology. In addition, Through 3D LiDAR scanning, the 3D point cloud of the structure was acquired, and the accuracy of reproduction and completeness of the 3D model based on the checkpoint were compared and reviewed with the UAS-based image analysis results. In particular, accuracy and realistic reproducibility were verified through a combination of point cloud constructed from UAS and terrestrial LiDAR. The results show that UAS - based image analysis is superior in accuracy and 3D model completeness and It is confirmed that accuracy improves with the combination of two methods. As a result of this study, it is expected that UAS and terrestrial LiDAR laser scanning combination can complement and reproduce precise three-dimensional model of vertical structure, so it can be effectively used for spatial information construction, safety diagnosis and maintenance management.
