Humans process aesthetic functions of objects such as form, size, color, and texture through vision, while at the same time observe them with a symbolic function by a new psychological interpretation based on their past experience. Therefore, it is more important to study and understand the thoughts and psychological influences of how humans perceive with their eyes than what humans simply look with them. With this research purpose in the background, this study will demonstrate in detail the cognitive characteristics of analog and digital images as a symbolic function with a "formative" point of view. Five hypotheses were established, which were proven through the following tests: smartphone, most frequently used in our daily lives, is simplified to a two-dimensional line drawing form, which is set to instances where the R(radius) is applied to the horizontal line of the two-dimensional form of smartphone, where Run-in-R(radius) is applied, and R(radius) rounding is applied to the edges of those shapes. The shapes were combined to form 12 pairs, which was used in a test to the test subjects. As a result, some human characteristics were observed; in specific, some helped prove objectively how humans perceived analog and digital images as psychologically stronger as a symbolic function. If people's thoughts and feelings gained through such study could be stored in database as one value and be provided to product designers, I believe it could be developed into design form as a basic emotional design that consumers desire.

The purpose of this study is to investigate the unique contrasting landscape characteristics of imperial tombs of Qing dynasty by examining the characteristics of facility layout in which location, Feng shui, and siblings are harmonized with the 12 Qing Dynasty Hwanggyeongchim. Through literature surveys, field observation and interviews, videos and drawing comparison, and inductive contrast analysis, the contrasting landscape characteristics of imperial tombs in the Qing Dynasty were analyzed by classifying them into natural environment, location, Feng shui, and formal esthetics. As a result, the characteristics of the location type and the layout plan of the Qing dynasty imperial tombs were derived from the analysis of Feng shui shape, axis extension distance along the midaxial line, the width of the ridge, the formality of the facility layout according to the difference between the height of the starting point and the end point, the leftward direction of the tomb, and the space ratio of the 'entry space' - 'ritual space' - 'burial mound space', etc. In addition, it was possible to derive the facility arrangement characteristics of tombstones through the analysis of the types and the arrangement order of tombs facilities, as well as the distribution, quantity and types of stone figures, while also revealing some contrasting characteristics different from those of the Ming Dynasty. In addition, it was confirmed that the spatial division effect through the water system and the view effect of the view from the midaxial line and the vista are the representative view effect found in the Qing Dynasty imperial tombs along with the density contrast.

This study is an image reconstruction method after cervical CT scan. According to the oblique coronal reconstruction angle, i would like to suggest the reconstruction angle that can best express neural foraminal bony stricture. The angle created by drawing a line passing through the center of the spinal cord in the midsagittal plane of the cervical spine and the uncovertebral joint was measured. A line passing through the center of the spinal cord was drawn from the neural foramen, and the angle formed with the midsagittal plane was measured and compared. At the C4-5 level, the average was 9.2°, at the C5-6 level, the average was 9.9°, and at the C6-7 level, the average was 8.4°, the neural foraminal angle was measured to be larger than the uncovertebral joint angle. There was a statistically significant difference in mean (p<0.01). Also, it was found that the angle increased toward the lower cervical vertebrae. The angle between the neural foramen of the lower cervical vertebrae (C5-6, C6-7) and the center of the spinal cord is between 55 and 60°. Here, if the oblique coronal image is reconstructed to be 90°, the degree of neural foramen stenosis can be observed well. Because it is an image reconstruction using a conventional CT scan image, it does not receive additional radiation exposure. It is of great significance in diagnosing cervical neural foramen bony stenosis.

Even though cartoons and narration comics were born from different origin, they have been called by names such as 'cartoons' or 'comics'. The reason can be found in the similarity of cartoons and narration comics. The similarity of cartoons and narration comics is the genre consisting of writing and drawing. Writing can be the format of expression and it can represent the story. Such story is present as a component of 'narration'. Sub genre of comics includes cartoons and narration comics. It includes animation in a broad range. In cases of narration comics and animation, it is thought that narration is present with continuity of time. However, in case of cartoon, because one or two cuts without continuity of writing are frequently expressed, it is being asked whether narration is present. It is easy to be reminded of epic or chanson de geste whenever you hear 'narration'. Since it deals with a biography of the character, we think the concept of 'narration' with temporality. However, narration provides a certain event in a broad range. Thus, cartoons presenting one event with the image may have the existence of narration, because description of multiple scenes of narrative comics can be implicitly represented in cartoons. As such implications leave a space, the empty space can be filled by active reasoning of recipients. However, nevertheless, it is very difficult to find studies as well as mentions of narration in cartoons. Thus, in this paper, we investigate the concept and structure of narration and demonstrate the presence of narration in cartoons. First of all, we looked at the narration theory in literature before studying narration in cartoons. The reason is that we thought the approach to the literary theory was required in order to investigate the basic elements, since cartoons are a collection of writing and drawing. We were focused on the prerequisites of narration presented in "story and discourse" of s. Chatman. If the prerequisites of narration are present, we can assume that the narration is present. The prerequisites are 'narration reasoning', 'screening', 'consistency', 'process statements' and 'stasis statement'. As s. Chatman described them as prerequisites of narration, he analyzed the narration structures of films and novels. In addition, we revealed that the narrations were present in cartoons as we identified how prerequisites of narration presented by Chatman were presented and expressed through "vocabulary of comics", "Timeframe" and "life in the line" described in "understanding comics" by Scott McCloud.

The purpose of this study was to investigate science integrated process skill of the students in science education center for the gifted. In order to do this, 'free-response test for the assessment of science process skills' developed by Yu-Hyang Kim(2013) was administered to 102 students(15 in elementary school science class, 58 in middle school science class I, and 29 in middle school science class II) who attend the program of science education center for the gifted in C university. The assessment tool measured 9 skills ; formulating inquiry questions, recognizing variables, formulating hypotheses, designing experiment, transforming data, interpreting data, drawing conclusions, formulating generalizations, and evaluating the designed experiments. As a result, the students in science education center for the gifted had relatively high scores in the area of 'formulating hypotheses' and 'recognizing variables', but they had relatively low scores in the area of 'transforming data', 'interpreting data', and 'evaluating the designed experiments'. The 2 items' percentage of correct answers were below 40% ; one is about a drawing a line graph in 'transforming data', and the other requires finding improvements of the experimental design in 'evaluation'. There was no significant difference between boys' scores and girls's one, and between the scores of students in the field of biology and those of students in the other fields(physics, chemistry, and earth science) in science integrated process skills. And there was significant difference according to the periods receiving the gifted education in 'formulating generalizations'. The teaching and learning has to focus on improving science integrated process skills in the program of science education center for the gifted and teaching and learning materials needs to be developed.

The purpose of this study was to verify (i) a consistent calibration verification for the assessment of method linearity and (ii) calibration agreement with calibration settings. We validated calibration verification through method linearity with different lot number of individual calibrators that span the working range for 9 tests except salicylate with control sample in test. We evaluated that it covered broad analyte range to assay from near zero to the top of the measuring range with 5 or 6 points every three times for 10 analytes in TDM test. Target values were plotted on X-axis with assigned or observed values on the Y-axis. Working range were as follows. Calibration verification of the measuring range (maximum to minimum values) has been validated asetaminophen 0.1 to $304.6_{\mu}g/mL$, salicylate 0 to $1005_{\mu}g/mL$, valproic acid 3.2 to $154.19_{\mu}g/mL$, digoxin 0.17 to 5.65 ng/mL, vancomycine 1.3 to $80.51_{\mu}g/mL$, carbarmazepine 0.1 to $22.3_{\mu}g/mL$, phenytonin 0.6 to $40.21_{\mu}g/mL$, theophyline 0.2 to $40.21_{\mu}g/mL$, primidone 0 to $24.07_{\mu}g/mL$, phenobarbital 0.6 to $60.0_{\mu}g/mL$. Drawing a straight line through five or six points of these data showed good linearity. We are sure that it is important to assess the calibration verification of a test method to ascertain the lowest and highest test results that are reliable.

The 13 genre paintings by Junkeun Kim in the book "Korean Games(by Stewart Culin 1858~1929)" were used to study the late $19^{th}$ century's basic costumes and Games style in Korea. The people who appear in the paintings are 26 adult males, 2 minor males, 2 adult females and 3 kisaengs. Typical men wore 'Jeogori' which had various colors and white linings with a reached hip line, and knotted with a 'go-rum' on the right side. They also wore, white colored 'Baji' with colorful sash that were knot below knee or ankle together with 'Hang-jun' or 'Daenim'. They wore 'Beoseon'. Some men wore 'Po' whose colors were blue, green, indigo, white. The general women wore 'Jeogori' in deep green and light pink, indigo, green, red, and they matched with colors for 'Kit' and, 'Go-rum', 'Kut-dong' and its 'Go-rum' was short and narrow. It was so fit and short with narrow sleeve. It had 'Dunggun-kit'(round head collar) with white 'Dong-jung' and so it fit at neck. They wore 'Chi-ma' whose color was red, light green, or light indigo. It contrasted with 'Jeogori'. The width of 'Chi-ma' was big enough. Then white inner slacks came out under the skirt. Traditional Korean games can be classified according to age and gender. Then the games can be further classified into three categories : men's games, women's games, and games for all. The games for adult are an archery practice, hunting, shovel work with a karae, making a bow, drawing Jongkung-chart, Korean chess, playing paduk, and the Korean card game. A swing is a game for women. Games for both men and women are dice play, and domino game. Games for both adult and minor males are sledge, and tightrope walking. Through genre paintings in the $19^{th}$ century, I reached a conclusion that basic costumes are similar to 'Hanbok' at the present time and the method of wearing them has not changed much. It appears that the originality of traditional costumes has been maintained.

Gwangtan-myeon, Paju-si, Gyeonggi-do was classified as a 4 grade age-class deciduous tree forest, however as a result of vegetation survey, this site was found to consist of natural forest with deciduous trees, thus causing difficulty in judging which age class it belongs to. Subsequently, the necessity of drawing up a detailed stock map plan was raised. For this reason, this research was designed to propose a mapping method for a detailed stock map plan based on a detailed survey on actual vegetation, vegetation structure, and analysis data on tree rings. The detailed analysis of actual vegetation pattern showed that there exist 22 patterns of vegetation, in which the natural forest has 11 patterns, such as Quercus mongolica forest and Q. variabilis forest, etc. while the artificial forest was found to have 6 patterns including Castanea crenata, etc. In order to verify their age-class, this research measured a tree age by collecting 42 quadrats and 89 specimen tree cores on the basis of a detailed actual vegetation map; as a result, an artificial forest and oak trees with small diameters located at low-lying areas, was categorized as 2-grade age class(covering 29.8%), and other areas were judged to be available for land use as 3-grade age-class(covering 57.6%) while the areas judged to be 4-or-more grade age-class (covering 8.8%) was impossible for land use because they are located on a steep slope ridge line on a boundary. In case a proposed site for a small-scale development is judged as a natural forest with deciduous trees as mentioned above, it is necessary that a detailed stock map plan should be drawn up through a detailed investigation into actual vegetation and analysis of plant gathering structure & specimen trees. A detailed stock map plan includes the data that makes it possible to comprehensively judge natural property, scarcity, and diversity of vegetation; thus, it is considered that a detailed stock map plan will be useful in judging the development propriety of a small-scale site.

There is a need for more accurate prediction in surgical orthodontic treatment. Video imaging is an important technology in planning orthognathic surgery and educating patients about the esthetic results after treatment. Preoperative and postoperative lateral cephalogram of 30 patients who had one piece Le Fort I osteotomy advancement and mandibular set back by bilateral intraoral vertical ramal osteotomy with or without genioplasty were used in this study. The computer generated soft tissue line drawing prediction were compared with the actual postoperative cephalograms .The results are as follows. 1. 14 variables showed Statistically significant differences from 24 variables between computer predicted profile and post operative profile 2. Most of the differences were found in the maxilla-related soft tissue landmarks. 3. The predicted results were more accurate in the groups who had small amount of mandibular set back. 4. The predicted results were more accurate in the groups who had no genioplasty. Most of these differences were within 2mm ranges. Therefore profile change prediction by video imaging could be considered clinically acceptable.
