1. Objectives This study was designed to research the relationship between Sasang Constitution and Framingham coronary risk score(FRS), 2. Methods 666 people, over 40 years old, were participated in the community-based cohort in Wonju, South Korea from July 2nd to August 30th in 2006, Sasang Constitutional Diagnosis was carried out using PSSC(Phonetic System of Sasang Constitution), face and tongue photos and a checkup list, Framingham coronary risk score(FRS) was calculated using previously studied sheets adopted from KCDC(Korea Center for Disease Control and Prevention). 3. Results The average FRS of men was 7,06 and that of female was 8,19 which was significantly higher than that of men. There were significant differences between Taeeumin and other constitutions in women, whereas no differences among male constitutions. Analyzing adjusted ORs for CHD risk intervals according to Sasang constitution, they were 0.96 in Taeeumin and 1.70 in Soyangin to Soeumin. Also 0.55 in Taeeumin and 3.39 in Soyangin to Soeumin in men, 1.96 in Taeeumin and 1.87 in Soyangin to Soeumin in women. Women had highet FRS than men and female Taeeumin group have highet FRS points and CRP than other constitutions. 4. Conclusions Regarding the positive relationship between FRS, APG and CRP, it is thought to be useful to understand APG and CRP results at the same time when calculating FRS. When it comes to prevention and screening of CHD, female Taeeumin should be more careful and female Soyangin also should have a consideration of heart disease.

Vyshyvanka, the embroidered folk costume shirt of Ukraine, originated during the early reign of the Slavs, and currently, it is also called Ukrainian embroidery. In cases of Vyshyvanka embroidery expressed in apparel elements, it is necessary to research formative characteristics for expanding the visual aspect through the diversification of techniques, but also the aspect of the psychological meaning to Ukrainians. This study aims to consider Vyshyvanka as a unique embroidery technique, and also analyze the formative characteristics expressed in apparel elements. The study of Vyshyvanka embroidery expressed in apparel elements can present meaning to understanding the Ukrainian fashion. The image materials for the analysis of Vyshyvanka design, included work photos contained in literary materials and foreign online visual materials. The results of formatively analyzing the Vyshyvanka embroidery expressed in apparel are as follows. First, the Vyshyvanka embroidery expressed in apparel elements held an incantatory meaning, protecting wearers from getting easily invaded by evil spirits. Second, the Vyshyvanka patterns utilized symbolism that implied the incantatory meaning. Third, a single color was used for the embroidery. Lastly, materials like cotton, that are easy to embroider, were mostly used. The formative characteristics of Vyshyvanka embroidery expressed in apparel elements implied the community spirit, nature worship, and folk beliefs. As an attempt to understand the Ukrainian fashion, this study is significant in the aspect of expanding, widely utilizing, and expanding the range of understanding of Ukrainian fashion. Therefore, there should be more active researches on Ukrainian fashion, so Vyshyvanka can be more widely used as a design element.

In the case of Drone Photogrammetry, the "pixel to point tool" module of Metashape, Pix4D Mapper, ContextCapture, and Global MapperGIS, which is a simple software, are widely used. Each SW has its own logic for the analysis of aerial triangulation, but from the user's point of view, it is necessary to select a SW by comparative analysis of the coordinate values of geospatial information for the result. Taking aerial photos for drone photogrammetry, surveying GCP reference points through VRS-GPS Survey, processing the acquired basic data using each SW to construct ortho image and DSM, and GCPSurvey performance and acquisition from each SW The coordinates (X,Y) of the center point of the GCP target on the Ortho-Image and the height value (EL) of the GCP point by DSM were compared. According to the "Public Surveying Work Regulations", the results of each SW are all within the margin of error. It turned out that there is no problem with the regulations no matter which SW is included within the scope.

The desire of humankind that longed for reappearance of visual makes progress within the development of linear history. The directing point at the moment was the 'eye'. Upon completion of setting the aiming point, visual image attempts reflection of main agent beyond reappearance of it and, by extension, aimed to visualize desire which was latent in the instance of main agent. It was able to experience a fantasy in paintings, photos and movies as a stage of desire, of course. Digital, however, suggested a new phasis in creating a fantasy world. This study aimed to research the fantastic nature in digital image that a fantastic image is created as a reflection of both independence and unconsciousness. As a result of research, this study revealed that digital image, as a channel that image and imaginative desire which were saved in id, is created as a perfect stage on the basis of verisimilitude, granting an experience toward realization of desire to a main agent raising id which was repressed by the ego and superego to the surface.

The vortical flow of a 65-deg flat plate delta wing with a leading edge extension(LEX) was examined through off-surface visualization, 5-hole probe and hot-film measurements. The off-surface flow visualization technique used micro water droplets generated by a home-style ultrasonic humidifier and a laser beam sheet. The angles of attack ranged from 10 to 30 degrees, and the sideslip angles ranged from 0 to -15 degrees. The Reynolds number was $1.82{\times}10^5$ for the flow visualization, and $1.76{\times}10^6$ for the 5-hole probe and hot-film measurements. The comparison of the visualization photos and the flow field measurement showed that the two results were in a good agreement for the relative position and the structure of the wing and LEX vortices, even though the flow Reynolds numbers of the two results were much different. The wing vortex and the LEX vortex coil each other while maintaining a comparable strength and identity at zero sideslip. Neither a looping of the wing vortex around the strake vortex, nor the lopsided coiling of the stronger strake and the weaker wing vortices was observed. At non-zero sideslip, the downward movement of the LEX vortex when going downstream was enhanced on the windward side, and the downward and inboard movement of the LEX vortex when going downstream was suppressed on the leeward side. The counterclockwise coiling of the wing and LEX vortices was decreased significantly on the leeward side.

The purpose of this study is to compare and analyze the perception of retro fashion and new-tro fashion using big data. TEXTOM allowed the collection of big data on the words 'retro fashion' and 'new-tro fashion', which was refined afterwards. As for the data collection period, Jan. 1, 2019 to Nov. 30, 2022 was set. A top 50 list of words were extracted from this data based on appearance frequency. The extracted words were processed through Network centrality analysis and CONCOR analysis using Ucinet 6. The results are as follows. 1) In retro fashion, the appearance frequency of 'style' was the highest, followed by 'sensibility', 'color', 'trend', 'fashion', and 'brand'. These words came up with high TF-IDF values. Network centrality analysis discovered that 'color', 'style', 'trend', 'sensibility', and 'design' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; trends, styles, looks, and photos. 2) In new-tro fashion, the appearance frequency of 'retro' was the highest, followed by 'trend', 'generation', 'style', 'brand', and 'fashion'. These words also came up with high TF-IDF values. Network centrality analysis found that 'retro', 'trend', 'generation', and 'brand' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; style, brand, clothing, and trend. 3) New-tro fashion is included in retro fashion in that it reproduces the styles of the past. However, it is taken completely differently from generation to generation. Unlike the older generations, millennials actively accept newly created clothes and brands based on the past styles. They perceive it as a fashion that reveals their own unique tastes and tastes.

Instagram is a Social Network Service(SNS) that has recently become popular among people of all ages and it makes people to construct social relations and share hobbies, daily routines, and useful information. However, since the uploaded information can be accessed by arbitrary users and it is easily shared with others, frauds, stalking, misrepresentation, impersonation, an infringement of copyright and malware distribution are reported. For this reason, it is necessary to analyze Instagram from a view of digital forensics but the research involved is very insufficient. So in this paper, We performed reverse engineering and dynamic analysis of Instagram from a view of digital forensics in the Android environment. As a result, we checked three database files that contain user behavior analysis data such as chat content, chat targets, posted photos, and cookie information. And we found the path to save 4 files and the xml file to save various data. Also we propose ways to use the above results in digital forensics.

According to the growth of the internet and the usage of software agents, the CAPTCHA that is a method for taking apart humans and computers has been widely deployed and used. As the results of many research activities, the CAPTCHA, which is spoken for a distorted image material including random text, has known to be easily breakable via artificial intelligence techniques. As one of alternatives for those text-based CAPTCHAs, methods using photos are concerned and various image-based CAPTCHAs are suggested. However, image-based CAPTCHAs still have some problems. In this paper, we discuss what are the problems in each image-based CAPTCHA and propose a new image-based CAPTCHA using image composition as the solution of those problems. Furthermore, for the secure operation of the CAPTCHA, we suggest a communication protocol that works without the virtual session and consider possible security and usability problems in the protocol.

In this paper, we design and implement a two-way search algorithm that can provide a customized service through the user with real-time two-way communication using a mobile instant messaging service. Therefore, we design and implement the automative search system which enables delivering message to each user mobile terminal from a plurality of relay mobile terminals by utilizing the mobile instant messenger, not to deliver a message from the main server to the mobile instant messenger user directly. Two-way search system using the mobile instant messenger can be immediately collect the user's response is easy to identify the orientation of each user, and thus can be provided to establish a differentiated service plan. Also, It provides a number of services(text, photos, videos, etc) in real-time information to the user by utilizing the mobile instant messenger service without the need to install a separate application. Experiment results, data processing speed of the category processing way to search for the data of the DB server from a user mobile terminal is about 7.06sec, data processing number per minute is about 13 times. The data processing speed of the instruction processing way is about 3.10sec, data processing number per minute is about 10 times. The data processing speed of the natural language processing way is about 5.13sec, per data processing number per minute is about 7 times. Therefore in category processing way, command processing way and natural language processing way, instruction processing way is the most excellent in aspect of data processing speed, otherwise in aspect of per data processing number per minute, the category processing way is the best method.

With the continued popularity of mobile devices such as smart-phones and tables, the development of the various kinds of digital contents making tools has not increased only the productivity of the digital contents, but also the demand of them rapidly. Geo-contents which means the digital contents related to location(geographic) information has enabled the user custom services. Especially, there are already some commercial location-based services that provide the user to POI (Points of Interest) with the geo-image contents such as photos tagged by the location. In the geo-video contents, there could be several related locations in the whole video, but only one representative location is used to tag a location to the video. In this paper, we have define the geo-video as a video content which has as many locations as the number of frames composing the video. We have also proposed the geo-video making tools and a viewer to create and utilize the geo-video contents. The geo-video contents proposed in this paper, are widely used in location based video contents searching services.
