The purpose of this study was to investigate the understanding of immunization and antibody test by region and age. The questionnaire was conducted for those who raised their dogs for more than two years. The survey consisted of 500 people. SNS. The results showed that the perception of the reinforcement vaccination was more prevalent than Seoul / Gyeonggi province. However, in the Seoul / Gyeonggi area, the recognition and comprehension of the antibody test was higher and the participation rate by age was the highest in the 20s. In addition, the percentage of people who knew about vaccination was much higher, and the understanding of reinforcement vaccination showed a similar rate. The results of the questionnaire showed that the importance of antibody test is more important than antibody vaccination. In the case of a large number of antibodies, the reinforcement vaccination should be performed at the appropriate time after the antibody test.

The objective of this study is to evaluate the mechanical behaviors and structural integrity of the weldment of high strength steel by using an acoustic emission (AE) techniques. Monotonic simple tension and AE tests were conducted against the 3 kinds of welded specimen. In order to analysis the effectiveness of weldability, joinability and structural integrity, we used K-means clustering method as a unsupervised learning pattern recognition algorithm for obtained multi-variate AE main data sets, such as AE counts, energy, amplitude, hits, risetime, duration, counts to peak and rms signals. Through the experimental results, the effectiveness of the proposed method is discussed.

The contact displacement sensors that are currently becoming popular in the shaking table tests are limited depending on their use environments; thus, the reality is that each equipment appears impractical considering its effectiveness and applicability. Therefore, in this study, to verify an algorithm for measuring the displacement responses of a structure using the line detection in the shaking table test, the test was conducted on a reinforced concrete frame.

Purpose – This paper aims to analyze and investigate to find out the appropriate ways to make an easy TBT of smart city. It is an important issue between Korea and China because TBT of smart city has lots of advantages in IT, S/W, IOT, and Home network. Research design, data and methodology – First, the paper made use of reviewing2nd data analysis and focused on group interview, and then compared with analysis on the international rule and system such as smart city system, technical regulation, and standard through test certification procedure and inspection. Second, this paper reviewed electric/electronic test, certification, and calibration. Third, through analyzing MRA between Korea and china, the paper focused on SDoC, Mutual Acceptance of International certification, and IECCB scheme. Results – Through the comparison and analysis, this paper found that it is important to promote multi-track agreements with the countries that need short-term promotion. Moreover, it is necessary to conclude an agreement with the leading countries in Middle East and Central America. Conclusions – Through the above the reviews and analysis, we can see the importance of promotion in FTA and MRA with the efforts to remove the obstacles and promote to make an easy TBT by MRA between Korea and China.
