  • From the perspectives of grammaticalization and corpus, the purpose of this study is to examine the motivation of the emergence of the split infinitives in American English and to discuss the justification of the split infinitives based on the corpus empirical data such as COHA and COCA. The formerly ungrammatical split infinitives in the form of [to + adverb + verb] are now definitely grammatical forms in Present Day English (PDE). The corpus-based data confirms the legitimacy of the split infinitives with the empirical reasons like clarifying sentences (i.e., disambiguation) or strongly focused readings. In addition, the split infinitives are natural consequences caused by the grammaticalization of an infinitival particle to and most crucially by the loss of verb movement. When verb movement to T position does not occur in infinitival clauses, the word order results in [to + AdvP + V], thus forming the split infinitives. The split infinitives are no longer a matter of discussion and will continue to increase in both formal and informal contexts as being definitely grammatical forms.

  • This study aims to understand the differences in cultural and emotional perceptions about the color image of public healthcare facilities in Romania, an Eastern European country that is relatively lacking in recognition but is gradually expanding trade. For this, color images were selected through a review of previous studies, and a questionnaire survey was constructed based on the colorimetric data by visiting 8 public healthcare facilities such as medical facilities, 4 social sports facilities, and 8 nursing facilities. An online survey was conducted on the color image of public facilities with 89 Koreans and 86 Romanians, and frequency and cross-analysis was conducted using the SPSS statistical analysis program to examine the color images of public healthcare facilities of Koreans and Romanians. The difference in perception was identified. As a result, it was found that there was a statistically significant difference in the perception of color images of public healthcare facilities between countries in vocabulary evaluation and image evaluation, and this was interpreted as different meanings for groups residing in different cultures. Therefore, it implies that cultural differences in perception should be considered when establishing an environment related to this in the future.

  • The present study aimed to evaluate the effect of radiation mutant Perilla frutescens var. crispa on bone metabolism and the inflammatory response in a monosodium iodoacetateinduced rat model of osteoarthritis. radiation mutant Perilla frutescens var. crispa was administered orally at doses of 25, 50 or 100 mg/kg/day for 2 weeks before direct injection of monosodium iodoacetate (3 mg/50 μl of 0.9% saline) into the intra-articular space of the rats' right knees. The rats subsequently received the same doses of oral radiation mutant Perilla frutescens var. crispa for another 4 weeks. It was evaluated that the treatment effects based on serum biomarkers, and morphological and histopathological analysis of the knee joints. Compared with those in control rats, the radiation mutant Perilla frutescens var. crispa treatments significantly reduced the serum levels of inflammation, bone metabolism markers (i.e., COX-2, LTB4, MMP-3, and COMP), and the amount of fibrous tissue. Otherwise, it was significantly increased the concentration of TIMP-1 and calcitonin. In addition, the radiation mutant Perilla frutescens var. crispa treatments effectively preserved the knee cartilage and synovial membrane. As a result, it indicates that radiation mutant Perilla frutescens var. crispa prevented and alleviated osteoarthritis symptoms. Thus, radiation mutant Perilla frutescens var. crispa can be used in food and drug material for the management of osteoarthritis.

  • The purpose of this study was to investigate in vitro antibacterial activities of pozzolan against super bacteria and intestinal bacteria. There were four treatment groups: 1) CON, pozzolan free control group; 2) DP0.3, microbial culture medium prepared by mixing distilled water and 0.3% of pozzolan powder; 3) DP0.5, microbial culture medium prepared by mixing distilled water and 0.5% of pozzolan powder; and 4) PE, microbial culture medium prepared with pozzolan powder extracts without adding distilled water. The count of Lacctobacillus casei was significantly higher in the DP0.3 group compared to CON (P<0.05). However, it showed no significant difference compared to other treatment groups. Numbers of Clostridium butyricum, Escherichia coli, and Salmonella typhimurium were significantly lower in pozzolanic treatment groups compared to CON (P<0.05). Clostridium butyricum and Salmonella typhimurium counts were significantly different among DP0.3, DP0.5, and PE groups (P<0.05). Counts of E. coli were also significantly between DP0.5 and PE groups (P<0.05). Counts of MRSA and VRE were significantly lower in pozzolanic treatment groups compared to CON (P<0.05). MRSA counts were significantly different among DP0.5, DP0.3 and PE groups. VRE counts were significantly higher in the order of PE > DP0.3> DP0.5> CON (P<0.05). These results suggest that pozzolan could be used as a dietary silicate supplement and a natural antibacterial agent for livestock if its antimicrobial activity against super bacteria and harmful bacteria in the intestine is confirmed.

  • This paper is to verify the effectiveness of 'Hybrid Disaster Management Strategy' that integrates 'RTM(Real-time Monitoring) based On-line' and 'UAV based Off-line' system. For landslide prone area where sensors were installed, the conventional way of risk management so far has entirely relied on RTM data collected from the field through the instrumentation devices. But it's not enough due to the limitation of'Pin-point sensor'which tend to provide with only the localized information where sensors have stayed fixed. It lacks, therefore, the whole picture to be grasped. In this paper, utilizing 'Digital Photogrammetry Software Pix4D', the possibility of inference for the deformation of ungauged area has been reviewed. For this purpose, actual measurement data from RTM were compared with the estimated value from 3D point cloud outcome by UAV, and the consequent results has shown very accurate in terms of RMSE.

  • This study attempted to derive the possibility of using wood pellet using rice husk, which is an agricultural byproduct, and tried to improve the lower calorific value of rice hulls thorough expansion technology and combustion additives. In the physical and chemical analysis of rice husk, the result was obtained that the chlorine content was 0.09%, which did not meet the wood pellet quality standard of Korea. When making rice hulls into expanded rice husk through the expansion technology, the chlorine content decreased, resulting in a product of 0.02%, which is equivalent to the wood pellet standard of Korea, and the calorific value was also increased to 4,280 kcal/kg compared to the existing 3,780 kcal/kg. To obtain a product of 5,000 kcal/kg or more, borax, hydrogen peroxide, and sodium hydroxide was used as combustion improver. However the improvement in calorific value was insufficient. After conversion to coffee oil path using coffee grounds, which is a waste resource biomass, it is mixed into an expanded rice husk, and when the product is analyzed, the coffee oil 15 wt% mixed product shows an excess of 4,949 kcal/kg. When using rice husk, an agricultural byproduct, as wood pellets, it is considered desirable to use waste resources to improve the calorific value, and according to the results of this study, when mixing coffee oil, rice husk can be sufficiently used as wooden pellets.

  • Today, banks around the world are making great efforts to adapt to the rapidly changing internal and external environment changes caused by the development of IT technology and to gain a competitive advantage in the market. In particular, in line with the rapid growth of smartphone usage, financial services are also provided in a variety of ways using Fintech, and one of the fastest growing areas is mobile simple payment. Mobile payment service is a financial service that pays the purchase price using a portable mobile device. As fintech, a convergence of financial services and information technology, it is recently used not only in financial services, but also in various industries. It is used in all fields where payment functions such as distribution are available. In the case of mobile cards, it shows that the usage rate of people in their 20s and 30s is increasing very much, so it can be said that the use of mobile payment services will continue to increase in the coming future. We know that simple payments are being used. However, it can be said that the research on the use of mobile payment services by these teenagers is somewhat incomplete. Therefore, this study investigated what factors are important for Korean teenagers to use mobile payment services. As a result, among the five hypotheses presented in this study, all hypotheses were adopted except for , which states that cash usage habits have no effect on innovation.

  • Recently, video-taping equipment such as CCTV have been seeing more use for crime prevention and general safety concerns. Since these video-taping equipment operates all throughout the day, the need for security personnel is lessened, and naturally costs incurred from managing such manpower should also decrease. However, technology currently used predominantly lacks self-sufficiency when given the task of searching for a specific object in the recorded video such as a person, and has to be done manually; current security-based video equipment is insufficient in an environment where real-time information retrieval is required. In this paper, we propose a technology that uses the latest deep-learning technology and OpenCV library to quickly search for a specific person in a video; the search is based on the clothing information that is inputted by the user and transmits the result in real time. We implemented our system to automatically recognize specific human objects in real time by using the YOLO library, whilst deep learning technology is used to classify human clothes into top/bottom clothes. Colors are also detected through the OpenCV library which are then all combined to identify the requested object. The system presented in this paper not only accurately and quickly recognizes a person object with a specific clothing, but also has a potential extensibility that can be used for other types of object recognition in a video surveillance system for various purposes.
