  • The tendency o taking supplements as the means of promoting health status has been increasing. This research was performed to reveal the influence of nutritional knowledge and health-consciousness on taking-supplements and to reveal that of general characteristics and related factors. The data were obtained by self-administering questionnaire and study population was adults aged 18-81 years living in Soul(N=1300) The overall response rate was 70%(N=910) The results can be summarized as follows: 1) A substantial percentage(82.5%) of the subjects used some kinds of nutrient supplements Forth nine percent of respondents used both drug type supplements and food type supplements 2) The main reasons for taking supplements were ; to prevent illness and to treat illness' and ' to recover from fatigue and to give me energy' The main reason for not-taking was 'Because I am Healthy' 3) The factors influencing on taking supplements were sex marital status disease exercise recognition of knowledge and health-consciousness. When the confounders of health-conscious-ness recognition of knowledge and self-estimated score were controlled threr were significant correlations between health-consciousness and taking-supplements.

  • 문자인식 즉 OCR(Optical Character Recognition)기술은 광학적으로 인식할 수 있는 문자를 컴퓨터가 읽을 수 있도록 하는 기술을 뜻한다. 문자인식의 근간이 되는 방법은 스트링 매칭 기법이 사용되어 왔지만 한글의 경우 자음, 모음, 자음 조합으로 만 가지 유형이 넘고, 더욱이 상용한자와 영어를 섞어 쓰기 때문에 오인식되는 경우가 많다. 본 논문에서는 한글이 수직선, 수평선, 사선과 같이 방향성이 강한 선소들로 구성되어 있다는 점을 이용하여 한글의 인식률을 높이는 방법을 제안하였다.

  • The synthesis and characterization of diastereomeric dodecanucleotides, d[GATCp(S)TCGAGATC], containing recognition sequence of the XhoI restriction endonuclease with a phosphorothioate internucleotidic linkage the cleavage site are described. Rp and Sp form of diastereomerically pure dinucleoside phosphorothioates d[Cp(S)T] were presynthesized and used for the addition to the growing oligonucleotide chain as a block. The stereochemistry of dinucleoside phosphorothioate was assigned by 31P NMR spectroscopy, enzyme digestion, and reverse-phase HPLC. XhoI restriction endonuclease cut only Rp diastereomer d[GATCp(S))TCGAGATC]. The rate of hydrolysis is slower than that of the unmodified dodecamer d[GATCTCGAGATC]. The phosphorothioate nucleotide is using for determination of the stereochemical course of the XhoI catalyzed reaction.

  • Agriculture is being damaged by harmful animals such as wild boars and water deer. It need to get permission to catch a wild boar and farmers are using a lot of methods to chase harmful animals. The methods through deep learning and image processing capture harmful animals with cameras. It is difficult to analyze harmful animals that are active at night. In this case, In this case, using deep learning by image correction can achieve a higher recognition rate.

  • Since the introduction of CRT(Cathode Ray Tube) in the 1950s, display technologies have been developed continuously. Flat panel displays such as PDP(Plasma Display Panel) and LCD(Liquid Crystal Display) were commercialized in the late 1990s, and OLED(Organic Light Emitting Diodes) and Micro-LED(Micro-Light Emitting Diodes) are now being developed and are becoming widespread. In the future, we expect to develop ultra-realistic, flexible, embedded sensor displays. Ultra-realistic display can be applied to AR/VR(Augmented Reality/Virtual Reality) devices and spatial light modulators for holography. The sensor-embedded display can be applied to robots; electronic skin; and security devices, including iris recognition sensors, fingerprint recognition sensors, and tactile sensors. AR/VR technology must be developed to meet technical requirements such as viewing angle, resolution, and refresh rate. Holography requires optical modulation technology that can significantly improve resolution, viewing angle, and modulation method to enable wide-view and high-quality hologram stereoscopic images. For electronic skin, stable mass production technology, large-area arrays, and system integration technologies should be developed.

  • As interest in augmented reality has increased recently, attempts have been made to incorporate augmented reality into various fields. In implementing augmented reality, the method by which markers are used is to extract feature points of markers to recognize 3D coordinates and, in some cases, it is necessary to recognize multiple markers simultaneously. Therefore, this paper proposes optimization methods for recognising multiple markers at the same time. Unity 3D and augmented reality library Vuforia are used to implement the experimental environment. The augmented reality program produced was implemented in an application form and tested using a mobile camera. We looked for optimization methods for manufacturing markers directly and for recognizing multiple markers through changes in the experimental environment. The results of the experiment can provide a higher recognition rate in an environment where multiple marker recognition is required later.

  • In this paper, we propose an automatic attendance management system for classrooms using OpenCV and machine learning technology. When a face photograph is input at the entrance of the classroom using a general purpose camera for PC, the attendance is checked by comparing the similarity of the face of the already stored student. In this study, the prototype was implemented using the machine learning library dlib, and about 10% of the students had a recognition rate of about 70%.

  • The purpose of this study is to find out what type of skip button used in forced exposure advertising is the most positive to the users. The four types of skip buttons were produced for the experiment and tested by survey and eye tracker to reveal the effects of the skip buttons on perceived intrusion, advertising attention, attitude toward advertising, and memory consisting of recall and recognition. Out of 80 participants, 20 were randomly assigned to the specific type of skip button group. The results showed that there is no statistical difference in advertising attention, perceived intrusiveness and attitude toward advertising. However, the recall and recognition rate are the highest in the static text type and kinetic text, product image, and default follow statistically. This study has implications for using skip buttons as a major variable for inventory of TrueView advertising effects and suggests that the amount of information in the image is critical processed by users within very short time.
