In this study, we optimize the discharge method using perforation by identifying the optimal perforation pattern and number. It involves forming perforations that penetrate the lithium-ion battery, resulting in complete discharge without generating wastewater containing hazardous substances. The study is conducted based on four different perforation patterns, and the optimal pattern and number are determined using temperature and residual voltage measurements. The results show that the voltage drop rate remains constant regardless of the type of perforation pattern, and the 1-row pattern exhibits superior results in terms of the heating temperature. This research contributes to the development of an eco-friendly and effective discharge method for lithium-ion batteries using perforation. Furthermore, the voltage drop experiment reveals that there is no significant improvement in the discharge time beyond the eight perforations. Consequently, the optimal number of perforations is determined to be eight.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115940022","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}

Due to the increasing importance of environmental protection, Korea enacted the ‘Resource Circulation Basic Act’ in 2020. On December 25th, 2020, the ‘Transparent PET Bottle Separate Collection Act’ went into effect in Korea, requiring that clear PET bottles be separated and disposed of in separate recycling bins after the labels are removed. However, according to a consumer survey conducted by the Korea Consumer Agency in 2021 on the separate collection of transparent PET bottles, more than 70% of consumers expressed that the removal of labels was the most inconvenient aspect. Therefore, in this study, we analyzed and compared the structure and form of PET shrink label perforation lines with eco-friendly labels introduced in the middle of transparent PET bottle labels from five selected domestic brands in Korea. As a result, we confirmed that the perforation of PET shrink labels may vary according to the structure of the perforation lines, as we found that the perforation structures of each brand were different from each other.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121334708","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 study results revealed that the characteristics of luxury brand products had a significant positive effect on the brand attitude and purchase intention. In addition, brand attitudes have a mediating effect in the effect of luxury brand product characteristics on purchase intentions. Notably, the higher the characteristics of luxury brand products such as originality, aesthetics, scarcity, and symbolism, the higher the purchase intention, and in this correlation, the consumer attitude toward the brand is further strengthened. Finally, examining the moderating effect of the consumption value of the MZ generation, the most important consumer group of luxury brand collaboration products, revealed that it had a significant moderating effect on the relationship between the brand attitude and the purchase intention. Therefore, if luxury brand companies actively utilize collaboration with other brands to provide high artistic designs, messages, or symbolic phrases desired by the times, they can eventually have a positive impact on the attitude and purchase intention of the brand perceived by MZ consumers.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125677329","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}

A survey was conducted on 198 foreign students attending University K located in Metropolitan City D. One-way analysis of variance (ANOVA) and t-test were conducted to investigate college life adaptation and interpersonal skills according to the factors of foreign students. This study identified Pearson correlation coefficients between Korean language level, part-time job time, part-time job income, interpersonal skills, and college life adaptation. In addition, multiple regression analysis established the effect of the aforementioned factors. College life adaptation and interpersonal skills showed an intermediate level, and the relationship between the Korean language level, interpersonal skills, and college life adaptation exhibited a positive correlation. Part-time job hours displayed a positive correlation. Korean language level and interpersonal skills had a positive effect on college life adaptation, but part-time job hours and income did not affect college life adaptation. This study suggests that a program that can increase the level of Korean and interpersonal skills is needed.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116788362","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}

In this study, an existing imported automatic screw dispensing device was analyzed. Air pressure consumption could be reduced by ~67% by applying design technology that decreases the number of divisions. Further, because the screw supply uses the principle of free fall by gravity, it is designed to be distributed and supplied as one part. Moreover, the working time is reduced by more than half because 12 screws can be distributed to the fastening device with one screw distribution unit. To alleviate the problem of the magazine unit, the screw is dropped immediately after being seated on the bolt knife. Consequently, the height of the driving part could be reduced by approximately one-third. Finally, static and dynamic analyses were performed to verify the suitability of the design—based on the results of analyses, the design was determined safe because the stress value was within both the yield strength range and elastic range. Furthermore, because the maximum deformation for the load condition was in the elastic section, this design could be verified as safe.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133738877","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 research subject is the K-Pop and C-Pop industries from the late 1990s to the present; , literature review and individual case analysis methods were adopted for effective analysis. The following plans for the development of the Chinese pop music industry were derived through SWOT analysis. Primarily, marketing strategies using Internet new media such as TikTok should be implemented, a “star-type” new singer training system should be established, and a service model that combines “O2O” online and offline consumption channels should be utilized. Subsequently, new singers should lead musical success through the formation of their own fandom culture with a strategy that goes beyond the existing older generation singers. The study aims to contribute theoretically and practically to the development of Chinese pop music by deriving implications for the Chinese pop music industry and presenting ways to develop Chinese pop music in a slump.","PeriodicalId":383838,"journal":{"name":"Korea Industrial Technology Convergence Society","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121862531","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}
