Stockigt sizing test, which is readily affected by individual tester's bias as well as testing conditions in recognizing red coloration, had to be modified to improve its reliability and reproducibility. The novel testing system with the automatic recognizing program of red coloration was developed with the auxiliary equipments including an automatic liquid dispenser and a specimen shifter. The analysis program used a hue value of a droplet image in recognizing a point of time on red coloration instead of RGB values that are not similar to human perception of color. Hue was more sensitive in recognizing the red coloration of a droplet than the other two factors, Saturation and Value. During the test, the program records the time consumed up to a specific hue value of a droplet on a specimen. Differently from the conventional test, the automatic test could obtain a reliable and reproducible sizing degree with a minor error. Furthermore, the Stockigt sizing degree measured by the automatic system showed great correlations with contact angle and Hercules sizing degree. It means that such great correlations will contribute to the development of an integrated measuring system capable of predicting contact angle, surface tension, surface energy and Hercules sizing degree of paper and paperboards through the Stbckigt sizing test. It was meaningful to note that the automatic system for Stbckigt sizing test might be able to used to predict contact angle, Hercules and Cobb sizing degree, based upon the high correlation coefficients.

This study examined the factors affecting the intention of the public to share electronic medical records(EMR) based on the theory of reasoned action and the privacy calculus model. It also investigated whether the purpose of EMR sharing varies depending on personal characteristics, such as the degree of interest in health and personal medical history. According to an online survey of 145 people, altruistic enjoyment, awareness of personal information protection, recognition of legal and institutional roles, and interest in health had a positive impact on the level of EMR sharing, and trust in hospitals positively adjusted the relationship between recognition of legal and institutional roles and sharing intentions. Accordingly, we confirmed that the public recognized the role of the government and hospitals in the sharing process as necessary. The public interest benefits of sharing are critical to activating public participation in the sharing of EMR, and it is also essential to prepare guidelines that legally guarantee the security and proper use of EMR.

Objective : Recently the number of health functional food (HFF) made with Traditional Korean Medicine (TKM) herbs have been increasing. However, there was a lack of the functional and safety information on HFF. Thus, this study was performed to investigate perceptions and consumptions of the HFF in Daegu area. Method : We used the data of 'Survey in Daegu' in 2010 and analyzed characteristics of perceptions and intake conditions of HFF of 1,208 participated inhabitants. Result : Among the 1,208 respondents, 30.4% were male and 63.5% were female. Most respondents (69.3%) were between 30's and 50's decade. The recognition rate of HFF made with TKM herb appeared to 86.2%. The major route of acquiring HFF information was 'mass-media' (49.8%) ; the primary reason of using HFF was 'For health promotion and anti-aging' (69.2%). On the other hand, the recognition rate of adverse effects was 53.3%. As for intake effect, 41.5% were satisfied at HFF consumption, while 56.0% did not feel special effects through the HFF consumption. In regards to purchase place, 'HFF store' was most selected by 38.0%. 69.1% of respondents selected to TKM decoction, the reason is that it made according to TKM physician's diagnosis considered their health condition. Conclusion : HFF intake was purpose to health promotion, but HFF made with TKM was consumed without any information about that. In order that HFF be used properly to promote health, the scientific and reasonable information of HFF made with TKM herb is need for consumers.

This study is significant in explaining the eSports awareness survey and future development direction of deaf people. Therefore, 189 deaf people were selected as the population, and the following conclusions were drawn by frequency analysis and t-test using SPSS 21.0 and Excel 2016. First, 67.7 percent of the 189 deaf people recognized eSports, 61.4 percent recognized it as a new sports system, and 65.6 percent participated directly or indirectly in eSports. Second, smartphones are the most common e-sports participating devices, and most of the participating events are Kartrider, which is recommended by friends. Third, the most inconvenient part of participating in eSports was the lack of eSports programs for deaf people, and the survey on whether to recommend eSports was the most likely. Fourth, the most common reason for not recognizing eSports as a new sport is that they are not actually sports, so they are not interested in participating. Fifth, there are statistically significant differences in eSports awareness, recognition and participation of deaf people by gender.

In this paper, we propose a hybrid camera system that combines cameras with different focal lengths and LiDAR (Light Detection and Ranging) sensors to address the core components of autonomous driving perception technology, which include object recognition and distance measurement. We extract objects within the scene and generate precise location and distance information for these objects using the proposed hybrid camera system. Initially, we employ the YOLO7 algorithm, widely utilized in the field of autonomous driving due to its advantages of fast computation, high accuracy, and real-time processing, for object recognition within the scene. Subsequently, we use multi-focal cameras to create depth maps to generate object positions and distance information. To enhance distance accuracy, we integrate the 3D distance information obtained from LiDAR sensors with the generated depth maps. In this paper, we introduce not only an autonomous vehicle platform capable of more accurately perceiving its surroundings during operation based on the proposed hybrid camera system, but also provide precise 3D spatial location and distance information. We anticipate that this will improve the safety and efficiency of autonomous vehicles.

The purpose of this thesis lies on building the foundation for the further activation of trade among the Northeast Asian countries such as South Korea, Japan, China, Russia, and North Korea through an analytical comparison of their arbitration systems. Further activation of trade cannot be reached without previously building safety measures on the negotiation of exports, the control on defective imported merchandise, the returns on investments, and the stable management of businesses. Throughout this thesis an analytical comparison of these five countries' most important areas on arbitration will be carried out. These areas are the arbitration laws and organizations; the structures of the laws; scope of arbitration; form of arbitration agreement, appointment of arbitratiors, place of arbitration, hearing, court assistance in taking evidence, governing law, decision making by panel of arbitrators, form and contents of awards, effective of award, recourse against award, recognition and enforcement of awards. etc. It was found in each of the areas cases to be identical, similar or verydifferent; also, cases unable to arbitrate. This phenomenon was found to occur due to the differences in political and economic systems and perception of arbitration among these countries. Additionally, this thesis points out what should each country do for its integration. It is also suggested the organization of a common arbitration research body to continue the efforts for raising the awareness, building trust, and mutual recognition among the countries to ultimately create a common arbitration system. Lastly, it is a personal will that this thesis will serve as the starting point for in depth researches in each of the presented areas.
