Consequently , data transmission in the broadcasting network is found to be low in loss, long-distance transmission is deemed possible, and stable optical signals can be amplified using domestic equipment instead of expensive foreign equipment. The tools developed in this study provide an opportunity to reduce dependence on overseas products by allowing domestic technology, which lacks optical amplifier technology, to compete with overseas products at a low price. In the future, these tools are expected to accommodate more members from the optical communication field and be applied to various fields that use high-power light.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129309819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results confirmed that the performance limitations that occur when the existing JavaScript is used in the process of processing large-scale contents in web software are actually very large.

In line with the latest trend, the demand for the knowledge and capabilities regarding AI is increasing. In this research, we suggest directions of the education in biotechnology and AI convergence. We employ the focus group interview(FGI) and the in-depth interview(IDI) to investigate the opinions of specialists belonging to biopharmaceutical, medical and AI fields. The results are summarized as follows. The convergence education of AI and biotechnology is presently required to the biotechnology trainee. Advancing into the bio-convergence industry is currently limited to college graduates majored in biotechnology. Specialists participated in this study affirm that bio major students should attain logic and mathematics in studying AI and programming, which leads to the direction of education with the convergence of AI and biotechnology. This research confirmed the AI proficiency required for bioconvergence workers and suggested the direction of vocational education to be implemented for college students and graduates in the future.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121462708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the 1960s to the early 1990s, the German government unilaterally supported Korea, and the two countries maintained mutual exchanges from the 1990s. It has grown into a partnership to build a cooperative relationship by jointly carrying out ODA projects. Meanwhile, Korea, as a donor country, has been promoting vocational education and training support projects in various developing countries for over 40 years, starting with the Indonesian Vocational Training Center support project in 1986, but there is no case of long-term cooperation such as that between Korea and Germany. Through the study on the development of the Korea-Germany long-term cooperative relationship, we are able to understand the need to build a sustainable growth model based on the demand in the field of vocational education and training in the recipient countries.
