Moderns are living within flood of web contents, animation, reflex data etc. as well as sight, product, environment design. There fore, modern consumer has much options. Designer must provide various result for consumer for this reason. And must invent new sensitivity and propose to consumer. As purpose of this MCC sensitivity palette research takes advantage of the most sensitive color, do. Because applying correct sensitivity more than when design with matter already settled, rid private prejudice, and is thing to convey design intention exactly to user. Excellent culture contents must be able to equip international color design sensitivity. MCC sensitivity palette research studies and carries on the head emotion and sensitivity language that is nationality first, and collect End arranged sensitivity adjective through data analysis and picture data analysis that is the next time research leader Munheonjeok. And distributed collected adjective equally, and arrange distributed adjective by field of each sensitivity and collect system. Do 3 colors, 4 colors color scheme in selected sensitivity adjective and completed Simheom version. Result of beta version research to color specialist and designer last digital palette through question and inquiry compose.

This study was carried out to assess adoptability and environment impacts of ultra low volume (ULV) pesticide spray solutions aerially sprayed by manned-helicopter. Uniformity of the deposited amount in paddy fields was uneven, showing $3.1{\sim}4.7$ times differences among surveyed sites. Drifting distance of aerially sprayed droplets from the target area was within 30 m in the wind direction and 20 m in the opposite direction. Most of the aerially sprayed pesticides were deposited in/on rice plants, while those in submerged paddy water and soil were relatively small. The degradation rate of the deposited pesticides was in the decreasing order of rice plants, paddy water and soil. Soil residues of pesticides in the aerially sprayed rice paddy fields after harvest ranged from non-detected to 0.201 mg/kg. However, no pesticides were detected in brown rice and rice straw. No phytotoxic symtoms were observed in rice plants and nearby non-target crops by the sprayed pesticides.

A QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) multiresidue method was developed for the simultaneous analysis of 124 pesticides in soil by LC-MS. The procedure involved liquid extraction of soil immersed with 0.2N $NH_4Cl$ by acetonitrile with 1% acetic acid, followed by anhydrous $MgSO_4$ and sodium acetate, and dispersive SPE cleanup with $MgSO_4$, primary secondary amine (PSA) and $C_{18}$. The extracts were analyzed with LC-MS/MS in ESI positive mode. Standard calibration curves were made by matrix matched standards and their correlation coefficients were higher than 0.99. Recovery studies for the validation were carried out using two type soils, loam and sandy loam, at four concentration levels (0.005, 0.01, 0.02, and 0.1 mg/kg). The recoveries of pesticides were in the range of 70-120% with < 20% RSD except 4 pesticides, Benfuracarb, Ethiofencarb, Pymetrozine, and Pyrethrin. This result indicated that the method using QuEChERS and LC-MS/MS could be applied for the simultaneous determination of pesticide residues in soils.

Opinions regarding interdisciplinary unification of medical laboratory science were analyzed by an online questionnaire distributed to 255 professors and 4,000 hospital practitioners in January of 2018. The recovery rate was 79 (30.9%) for professors and 1,368 (34.2%) for hospital practitioners. In the perception survey on the duality of interdisciplinary, both the professors and the hospital practitioners reported that they felt interdisciplinary integration is necessary. The prerequisite of four-year integration was the establishment of institute of accreditation and standardization of curriculum, and the requirements for the four-year integration were considered important for adjustment of student quota and standardization of curriculum. In the four-year integrated approach, the opinion that only universities that passed the accreditation evaluation should operate a four-year system was highest among professors and hospital practitioners. The optimum capacity of university students was less than 40 in cases of 4-year integration. In conclusion, the above results suggest that the professors and hospital practitioners realize 4-year interdisciplinary integration is necessary to produce a competent medical technologist, and the institute of accreditation, standardization of curriculum, and student quota adjustment should be presupposed for 4-year integration.

Recently, researches on DBRN(DataBase Referenced Navigation) system are being carried out to replace GNSS(Global Navigation Satellite System), as weaknesses of GNSS were found that are caused by the intentional interference and the jamming of the satellite signal. This paper describes the gravity gradient modeling and the construction of EKF(Extended Kalman Filter) based GGRN(Gravity Gradient Referenced Navigation). To analyze the performance of GGRN, fourteen flight trajectories were made for simulations over whole South Korea. During the simulations, we considered the errors in both DB(DataBase) and sensor as well as the flight altitudes. Accurate performances were found, when errors in the DB and the sensor are small and they located at lower altitude. For comparative evaluation, the traditional TRN(Terrain Referenced Navigation) was also developed and performances were analyzed relative to those from the GGRN. In fact, most of GGRN performed better in low altitude, but both of precise gravity gradient DB and gradiometer were required to obtain similar level of precisions at the high altitude. In the future, additional tests and evaluations on the GGRN need to be performed to investigate on more factors such as DB resolution, flight speed, and the update rate.

Platform screen door (PSD) installed at underground subway station has reduced the safety accident, but it may cause poor air ventilation condition due to the isolated exhaust duct in the subway tunnel area. In this study, the additional ventilation system was suggested, which can be installed at a void space (i.e., storage room under stairs) of platform in order to improve efficiency of air ventilation rate. Exhausted air from platform was directed to underneath of platform and joined with existing ventilation duct of train exhaust system (TES). One subway station in Seoul city was selected to predict the effectiveness of the suggested lower exhaust system by using the computational fluid dynamics (CFD) analysis. The predicted mean age of air was decreased by 16.5% which proves the improvement of air ventilation efficiency when the suggested lower exhaust system was applied.

KDC-1 canister for PWR spent fuels which will be used for the Korean Reference Disposal System was developed. The structural analysis of the canister was carried out as a part of the safety analysis. Two conditions, disposal condition and handling condition, were considered for the structural analysis. Three kinds of load cases, normal, abnormal and rock movement, were considered for the disposal condition. The results of the calculation showed that the safety factors from the structural analysis were greater than the design requirements. Two accident scenarios, gripper failure accident and canister drop accident, were analyzed for the handling condition. According to the gripper failure scenario analysis, the handling machine with grippers could be used even in the cases that one or two grippers failed. The maximum von Mises stress from the canister drop accident scenario was 0.762 MPa, which was negligible compared with the yield stress of nodular cast iron. The proposed KDC-1 canister for PWR spent fuels proves to be safe under the repository condition that is based upon the Korean reference disposal system according to the structural analysis for disposal condition and handling condition.

This article addresses considerations, processes of drawing concepts and design approaches in compiling a corporate brochure set in the practice of editorial design. A well-made brochure does not simply refer to listings of the current state of a company and a fantastic visualization of their visions. It necessarily involves the utilization of strategic core keywords appropriate to the industry, proper and classy metaphors that fit the target, a certain harmony between direct and indirect narratives, and bringing all of these aspects under the hat of creative and purposeful design in a single brochure. Thus, it also calls for variety and changes to captivate the eye when leafing through brochures. 1. Does the brochure reflect accurate diagnoses on the position of the market environment, the industry and their needs? 2. Does it offer solutions to given tasks, does it claim to be able to solve problems a company may have, does it satisfy their expectations, and does it cover the topics in an in-depth manner? 3. Referring to questions 1 & 2, does it address existing cases of competitors, leading players and global trends? 4. Does it have an appropriate design language that can communicate intrinsic issues and global trends as well as appropriate rhetorical visual aids that stand out?

Hallyu in East Europe has been spread since the end of the 2000s and contributed to boost the familiarity and favorability of Korea. Hallyu in East Europe started from Romania and Hungary, Korean dramas and K-Pops spread to Bulgaria. Korea and Bulgaria established a diplomatic relations in 1990; however, people of both countries do not share enough information or knowledge on each other. This study aims to understand the meaning of Hallyu and the ways of building cultural relations through Hallyu based on the cognitions and attitudes toward Korea and Korean culture in Bulgaria. It conducted the Focus Group Discussions(FGD) for 24 Sofia residents in their 20s and 30s. The FGD questions were mainly on the level of familiarity and of impacts of Hallyu in Bulgaria. The Hallyu in Bulgaria is still not so popular although Hallyu has been promoted through the diverse activities of Korean Embassy, Sofia University, Korean language institutions, and the Hallyu fans. The economic and cultural impact of the Hallyu is not yet viable in Bulgaria. In order to be recognized as one of the foreign popular culture in Bulgaria, Hallyu should be promoted with various endeavors for Bulgarian people to experience Korean culture beyond Korean drama and K-Pops based on the understanding of socio-cultural characteristics of Bulgaria. Then, Hallyu will be spread by producing Korean dramas, films, and K-pops reflected by local cultural characteristics in Bulgaria and hybridity of Korean popular culture.

In order to develop the indicators of environmental impact of pesticide, its actual usage in paddy rice was surveyed, and usage trends of individual pesticides were evaluated. The tendency of pesticide use indicated insecticide 43%, herbicide 29%, fungicide 27% and top ranking item in insecticide, herbicide and fungicide was carbofuran, molinate + pyrazosulfuran-ethyl, IBP. The usage statistics of formulation types showed GR>DP>WP>EC>FG>SP. Pesticide usage(a.i.) per hectare was 7.13kg and total usage for paddy rice was estimated at 8,387 M/T. In the result of comparison of fact-usage with pesticide consumption reported in 1998, the fitness was 94.7% for fungicide, 84.3% for insecticide, 77.8% for herbicide. The result of monitoring pesticide residue of unpolished-rice sampled from farm house of survey indicated 0.14 ppm(BPMC), 0.16 ppm(Isoprocarb), 0.17 ppm(Isoprothiolane). In case of rice straw, the residue level was 0.27 ppm(Isoprothiolane), 0.28 ppm(IBP), 0.39 ppm(Carbofuran). The residue levels of pesticides were below MRLs.
