Background: In modern society, the number of households raising companion animals increases, and the market for veterinary medicines is expanding even more. This study aims to investigate the perception of companion animal lovers' veterinary medicines, the necessity of specific guidance by pharmacists for veterinary medicines, the role of pharmacists at veterinary pharmacies, and ways to fulfill that role. Methods: This study evaluated veterinary medicines and medication guidance through Google online questionnaire targeting pet-lovers from December 20, 2021, until January 19, 2022. The questions consist of 1) characteristics of petlovers, 2) purchase history and drug recognition of veterinary drugs, 3) use of veterinary vaccines, 4) use of diagnostic kits, and 5) guidance of veterinary medicines by local pharmacists. Results: The respondents' experience purchasing veterinary drugs was as high as 94.4%. The most purchased drug was heartworm-preventing products, and vaccination was performed mainly at veterinary clinics (veterinarians). The respondents primarily purchased veterinary medicines for companion animals at veterinary hospitals and did not know the name of the drugs which they bought. In addition, respondents expected to receive specific information on veterinary medicines from pharmacists. Conclusion: As the number of veterinary pharmacies in the community will increase with the expansion of the companion animal market, pharmacists should play their role as experts in veterinary medicines through systematic and continuous professional education.

It is important to compare and analyze digital camouflage from different countries to promote the continuous development of a camouflage combat uniform. This effort should lead to developing a camouflage pattern suitable for the domestic environment and expand its performance of night camouflage. This study investigates digital camouflage by comparing camouflage fabrics sampled from Korea and eight other countries (USA, UK, Singapore, Croatia, Colombia, and Mongolia) in terms of textile, near-infrared reflectivity of colors, and color distribution. First, the fabric construction of camouflage from Korea, UK, US, Singapore, Span, and Croatia were all characterized by derivative plain weaves, while derivative twill weaves were generally used in Croatia and Mongolia. It is assumed that derivative plain weaves are adopted to improve the tearing strength of fine yarns. However, twill weaves enhance the flexibility of coarse yarn fabrics. Next, reflectivity change was analyzed based on camouflage color. The reflectivity of a combat uniform in Korea, Colombia, Croatia, and UK increased before 780nm in the visible light range, but remained consistent from 800nm which falls under the near-infrared range. In contrast, camouflage samples in Mongolia, Span, Singapore and USA showed a gradual increase of reflectivity in the near-infrared range. Finally, the color distribution analysis of digital camouflage found that camouflage of countries with desert or woodland combat settings dominantly contained brown colors. It indicates the color pattern consideration of different geographic regions is important to determine camouflage performance. This research involves basic study that will have implications for developing patterns and colors suitable for the South Korean environment and expand its use as night camouflage that helps achieve continuous improved camouflage performance.

Changes in weed floras and development of plant resistance to herbicides seemed to be closely related with increased and repeated use of herbicides. Herbicide use increased from 5% of the total consumption of pesticide in 1950 to 45% in 1976 in world basis. About 200 herbicides have been introduced to agriculture so as to control about 206 weed species which have been recorded important to human beings. In Korea, there was about 351 times in increased use of herbicides from 1966 to 1982. Interspecific selection by herbicide is mainly responsible for changes in weed floras and resulted in varying tolerance or susceptibility to herbicides, together with the changes of agricultural practices. The present trend toward continuous cereal cultivation throughout world will lead to type of changes in weed floras favorable to therophyte which can survive under unfavorable conditions as seeds rather than the types of geophyte which can survive unfavorable seasons as buds placed below soil surface. However, geophyte such as Sagitaria pygmaea, and Scirpus jurtcoides, and Cyperus rotundus and Cynodon dactylon in temperate warm climate become severe paddy weeds, presumably because of the removal of annual weeds by herbicides. Since differential tolerance to 2,4-D was firstly reported in Agrostis stolofera, about 30 species of weeds in 18 genera are presently known to have developed resistance to triazine herbicides. Resistance of weed biotypes to triazine herbicide is not mainly due to limited absorption and translocation or to the difference in metabolism, but is the result of biochemical changes at the site of metabolic activity, such as a loss of herbicide affinity for triazine binding site in the photosystem II complex of the chloroplast membrane. Genetical study showed that plastid resistance to triazine was wholly inherited through cytoplasmic DNA in the case of Brassica campestris. Plant tissue culture method can be utilized as an alternate mean of herbicide screening and development of resistance variants to herbicides as suggested by Chaleff and Parsons. In this purpose, one should be certain that the primary target process is operational in cell culture. Further, there are a variety of obstacles in doing this type of research, particularly development of resistance source and it's regeneration because cultured cells and whole plants represent different developmental state.

Objectives : The purpose of this study was to investigate the efficacy of Abelmoschus manihot (A-M) on the facial skin by observing the changes in the skin caused by continuous use of the essence containing A-M. Methods : Fifty-one participants were enrolled, 38 were classified as experimental group and 13 were classified as control group. Before the beginning of the test, the skin condition of the participants was investigated with the facial analyzer. An essence containing A-M was provided to the experimental group, and an essence base not containing Abelmoschus manihot was provided to the control group. Participants were asked to use the product in the morning and evening after washing their face. We checked the skin change status every 2 weeks and performed the test 3 times for 6 weeks. Results : In the case of t-zone oil and pores, there was a significant decrease in the experimental group. In the case of moisture, a significant increase was observed in the control group, but the significance was significantly increased when the essence containing A-M was used. In the case of elasticity, it was found that the experimental group continued to increase with the period of use. Conclusion : It is thought that the essence containing A-M will be effective in preventing skin aging through the reduction of t-zone oil, the size of the pores, and the increase in moisture and elasticity.

A bolt manufacturing process is completed with continuous forging. Technical and economical success of each process will depend on the appropriate process design and metal mold design for each procedure. This study aims to analyze the moldings of first and second steps among the multi-step molding processes of SCM435 bolt by use of the finite element method in order to achieve the reasonable process. Since the processes of first and second steps analyzed by use of the finite element method consist of axial symmetry, the transformed configuration of material satisfy the dimensions expected in process. In addition, the uniflow line formed in material becomes smooth and consistent over the entire process. Therefore neither molding of material nor inherent defect is expected.

Although the demands for the dredging work have been increasing due to social and industrial reasons including national plan for restoration of four major rivers, environmental standards or management guidelines for the dredged river sediment are limited. The suggested environmental standard for the beneficial use of dredged river sediment consists of two levels, recyclable and concern, and includes eight contaminants such as metals and organic contaminants. The systematic approach to remediate dredged river sediment is also suggested. The system consists of both washing and stabilization processes with continuous multi particle separation. In the early stage, the sediments are separated into two particle sizes. The coarse-grained sediment over 0.075 mm, generally decontaminated with less trouble, follows normal washing steps and is sent for recycling. The fine-grained sediments under 0.075 mm are separated again at 0.025 mm. The particles bigger than this second separation point are treated in two ways, advanced washing for highly contaminated sediments and stabilization for less. The lab test results show that birnessite and apatite are most effective stabilizing agents among tested for Cd and Pb. The most fine residues, down-sized by continuous particle separation, are finally sent for disposal. The system is tested for metals in this study, but is expected to be effective for organic contaminants included in the environmental standard, such as PAH and PCE. The feasibility test on the field site will be followed.

In this paper, we analyze trends in the use of mobile forensic technology, focusing on cases where mobile forensics are used, and we predict the development of future mobile forensics technology using linear regression used in future prediction models. For the current status and outlook analysis, we extracted a total of 8 variables by analyzing 1,397 domestic and foreign mobile forensics-related cases and newspaper articles. We analyzed the prospects for each variable using the year of occurrence as an independent variable, seven variables such as text (text message usage information), communication information (cell phone communication information), Internet usage information, messenger usage information, stored files, GPS, and others as dependent variables. As a result of the analysis, among various aspects of the use of mobile devices, the use of Internet usage information, messenger usage information, and data stored in mobile devices is expected to increase. Therefore, it is expected that continuous research on technologies that can effectively extract and analyze characteristic information of mobile devices such as file systems, the Internet, and messengers will be needed As mobile devices increase performance and utilization in the future and security technology.

If continuous moving objects are managed by conventional database, it is not possible for them to store all position information changed over time in the database. Therefore, a time period of regular rate is determined and position information of moving objects are discretely stored in the system for every time period. However, if continuous moving objects are managed as discrete model, we will have problems which cannot properly answer to the query about uncertain past or future position information. To solve this problem, in this paper, we propose the method and algorithm which use the history information stored in the same database, to estimate the past or future location of moving objects. The cubic spline interpolation is used to estimate the past location and the mean movement value of the history information is used to predict the future location of moving objects. Finally, from the location estimation experimentation of using virtual trajectory and location sample, we proved that the proposed cubic spline function has less error than the linear function.

, 2007 firm by Joe Wright, deals with tragic love of Cecilia and Robbie. While the 2001 novel of the same name focuses on Briony narrative the movie is seen through romantic relationship of two lovers. However, Briony's narrative in the movie helps to accent the two's love story. The director's emphasis on the love story is unfortunately from Briony tragic story. The continuous build up of misunderstanding and irreconcilable regrets begins to materialize and explodes in the middle of the film. The director manages to use just one day and uses the same location to illustrate the background of the characters as well as build up of the plot's misunderstanding. The study will focus on the beginning of the film that enabled the beautiful love story through effect and symbolic visual expression and techniques- especially the use of mise-en-scene, camera movement, framing, and lighting and how it emphasis and use of specific color and sound.
