The purpose of this study is to examine misnomers about King Heungdeok's "Prohibition of Clothing" by comparing the writings of Jeongdukbon [正德本] and Juzabon [鑄字本], which were different versions of the original texts of "Samguksagi [三國史記]", with 11 related books written between 1948 and 2012. In addition, this study is reconsidered the terms about several clothes as well as the values of fabrics. The study has come up with the following conclusions. 1. We suggested the correction about a misnomer in the 11 books and the misnomers for fabric items appeared most frequently. The records of Jeongdukbon about some of the items were different from ones of Juzabon, especially regarding noble woman's sash were written according to the record of Juzabon in most of the related books. However, when the commonplace woman's sash was taken into consideration, we could suppose that the record of Jeongdukbon was more reliable. 2. We examined the terms for Yodae [腰帶] and Yoban. It can be inferred from the original texts that the Yodae were different in material and function compared to the Dae [帶]. In other words, the wearing position of male's metal Yodae was the waist, whereas the females wore their Dae made of fabrics on their chest. An example of this can be seen from the female clay images of Tomb Yonggang-dong [龍江洞]. Moreover, female's Yo and Ban were distinct items on the basis of documents. For this reason, we suggested that Yodae and Yoban should be separated and written in books. 3. We suggested that Ju [紬, silk tabby] might be valuable according to an result of analysis about the value of recorded fabrics. Besides, Po [布, hempcloth] presumably were used as higher quality fabric than Myeonju [綿紬, silk tabby] on some items because Po was graded on the density by each class.

A numerical simulation of unsteady axisymmetric turbulent flow was performed for a reciprocating engine including port/valve assembly. The governing equations based on a nonorthogonal coordinate formulation with Cartesian velocity components were used and discretised by the finite volume method with non-staggered variable arrangements. The modified $\kappa-\xi$. turbulence model which included the effect of compressibility was used. The results of twodimensional transient calculation for the axisymmetric configuration were compared with the experimental data. Although slightly low rms velocity was predicted compared to the experimental data, predicted velocity distributions at the valve exit and in-cylinder region showed good agreements with the experimental data. The flow at the valve exit was separated at the same valve lift position with the experimental data. Two vortices incylinder region were generated during the initial intake process. The clockwise main vortex became strong and moved upward to the top wall. The counter-clockwise second vortex became weak and stick to the upper left corner of the cylinder. After middle intake process, new vortex adjacent to upper cylinder wall appeared by the piston motion and therefore, the in-cylinder flow was formed into three vortices. The cylinder pressure just before bottom dead center of piston was higher than inlet pressure and then the reverse flow occured at the valve exit. The in-cylinder flow characteristics were strongly dependent on piston motion, but insensitive to valve motion.

The history of make-up can go back to the beginning of human being and it can’t be separated from women’s life. The change of history and women's position have given make-up different form and meanings. So make-up becomes another text which can read social·cultural specialty. This study has tried to find out make-up as women culture for women have experienced make-up in a specific situation for a long time and a suit of make-up experience from self-retrospect and made an open channel for women and this paper checked out the possibility of alternative make-up culture. This research used new audience theory of cultural studies which is used for communication study and studied active meaning-construction process and its resistance pleasure. This study saw women as independent subjects not passive victims and how make-up has been different meanings in women’s life. And what pleasure is made and how the way of resistance made constructed in the regulation of make-up.

A fully automated high performance liquid chromatography with column-switching was developed for the simultaneous determination of KR60436, a new reversible proton pump inhibitor, and its active metabolite O-Demethyl-KR60436 from rat plasma samples. Plasma sample (50$\mu$l) was directly introduced onto a Capcell Pak MF Ph-1 column ($10{\times}4$ mm I.D.) where primary separation was occurred to remove proteins and concentrate target Substances Using acetonitrile-Potassium Phosphate (PH 7, 0.1 M) (2 : 8, v/v). The drug molecules eluted from MF Ph-1 column were focused in an intermediate column ($10{\times}2$ I.D.) by the valve switching step. The substances enriched in intermediate column were eluted and separated on a Vydac 218MR53 column ($250{\times}3.2$ I.D.) using acetonitrilepotassium phosphate (pH 7, 0.02 M) (47:53, v/v) at a flow rate of 0.5 ml/min when the valve status was switched back to A position. The method showed excellent sensitivity (detection limit of 2 ng/ml) with small volume of samples ($50{\mu}$l), good precision and accuracy, and speed (total analysis time 24 min) without any loss in chromatographic efficiency. The response was linear ($r^2{\geq}0.797$) over the concentration range of 5-500 ng/ml.

Inter-specific relationships among six species and two varieties, belonging to Scrophularia (Scrophulariaceae), in Korea were re-examined based on both morphological and molecular data. Scrophularia takesimensis, a Korean endemic species, should be separated from S. grayana as an independent species based upon unique morphological characters such as non-winged stems, thickened leaves and glabrous surfaces of leaves, even though they share a lot of other features. It was found that S. grayana is distributed in Sokcho in Korea and along the coast of the East Sea north to far eastern Russia. Although some morphologies of three taxa, S. cephalantha, S. koraiensis var. velutina and S. kakudensis var. microphylla appeared to differ from each other, their ITS DNA sequence data was similar to that of S. kakudensis, suggesting that they might better be designated with the later species. The taxonomic position of S. koraiensis, only found in Korea, has been ambiguous, but ITS DNA sequence data in this study revealed that this species is distinct from S. kakudensis. Consequently, we conclude that the genus Scrophularia in Korea includes five species.

This study presents a molecular phylogenetic analysis of the harmful dinoflagellate Cochlodinium polykrikoides, by use of partial sequence of small subunit (SSU) rRNA gene from most of the major taxa(24 species) in dinoflagellates. The class Dinophyceae clade formed a strong monophyletic relationship with C. polykrikoides and several taxa. On the basis of deeper nodes, the phylogenetic relationships placed C. polykrikoides closer to the order Prorocentrales rather than to the order Gymnodiniales, which was supported by a strong bootstrap value (100%) in the analyses of Neighbor-Joining and Parsimony methods. There is strong support for C. polykrikoides being placed in the same branch as Gymnodiniaceae and being connected in a clade with Prororcentrum micans among Prorocentrales. Morphological data show that C. polykrikoides is well associated with the genus Gyrodinium; however, this species is genetically closer to Gymnodinium than to Gyrodinium. The placement of C. polykrikoides always formed an independent branch separated from other dinoflagellates. In conclusion, planktonic P. micans plays an important role as an ancestor of Gymnodinium, whereas C. polykrikoides appears to be used an intermediate position between P. micans and Gymnodinium based on evolution.

PA(postero-anterior) and AP(antero-posterior) chest projections are the most sought-after types of all kinds of projections. But if a radiological technologist puts wrong information about the position in the computer, the orientation of left and right side of an image would be reversed. In order to solve this problem, we utilized CNN(convolutional neural network) which has recently utilized a lot for studies of medical imaging technology and rule-based system. 70% of 111,622 chest images were used for training, 20% of them were used for testing and 10% of them were used for validation set in the CNN experiment. The same amount of images which were used for testing in the CNN experiment were used in rule-based system. Python 3.7 version and Tensorflow r1.14 were utilized for data environment. As a result, rule-based system had 66% accuracy on evaluating whether the orientation reversal on chest x-ray image. But the CNN had 97.9% accuracy on that. Being overcome limitations by CNN which had been shown on rule-based system and shown the high accuracy can be considered as a meaningful result. If some problems which can occur for tasks of the radiological technologist can be separated by utilizing CNN, It can contribute a lot to optimize workflow.

SMB (simulated moving bed) is a continuous chromatographic process by shifting periodically port position. Binary of mixture, Blue dextran and Orange G, was separated by SMB. These components have unique color individually, that is, Blue dextran is blue and Orange G is orange. It is easy to understand SMB process by observing the shift of color changes in SMB. These components was not adsorbed to stationary phase and isolated by difference of size exclusion factor. Mass transfer coefficient was determined by single pulse test under several flow rate conditions. Operation condition was obtained by standing wave theory and optimized for high purities in extract and raffinate streams. Experiment was performed in open loop 4 zone (2-2-2-2) SMB. There are several advantages in open loop SMB, where extract is product for high purity. It is also easy to control flow rate and monitor experimental state during operation. Experimental, extract and raffinate history is well fitted with simulation results, however, column concentration profile is a little different from simulation results. Purities were 99.5％ for extract and 98.9％ for raffinate and extract and raffinate yields were obtained as 98.9％ and 99.4％ respectively.

The implementation of vision system using CCD camera which measures the earing rate of aluminium CAN is represented in this paper. In order to optimize the input image, the object of the input image is separated and the position of the image is calibrated. In the preprocessing, the definition of image is improved by the histogram equalization, and then the edges of the input image are detected by the Robert mask. The heights of the four ears and angles of the aluminium CAN are measured manually with the digital vernier calipers in industry. It takes 30 seconds to measure manually the height of one direction of the aluminium CAN at least three times. However, when the proposed system in this paper is applied, it takes 0.02 seconds only. In conclusion, the efficiency of the proposed system is higher than that of the system used in the industry.
