The survey period was from May 16 to June 30, 2019, and 1,048 responses were analyzed after excluding non-collected and inadequately completed responses. Confirmatory factor analysis and structural equation analysis were conducted using SPSS 23.0 and AMOS 24.0. Modified models were analyzed because initial models poorly fitted data. The modified confirmatory factor analysis model showed good fitness with CFI=0.953, NFI=0.945, TLI=0.925, RMSEA=0.069. Factor loading (standardized estimates) confirmed that the 15 measured variables represented latent variables well and that latent variables were correlated at a significance level of 0.001. The modified structural equation model showed good fitness with CFI=0.953, NFI=0.945, TLI=0.906, and RMSEA=0.069. The path coefficients for the 17 hypotheses were all statistically significant, and thus all the alternative hypotheses were accepted. Food hygiene recognition was found to have a significant effect on food hygiene attitude (β=0.384, p<.001), and food hygiene attitude had a significant effect on personal hygiene control (β=0.909, p<0.001). Food hygiene recognition had a weak effect on food hygiene attitude, but food hygiene attitude had a stronger effect on personal hygiene control. These results demonstrate the need for regular food hygiene education to improve food hygiene attitude because it had a greater influence on personal hygiene control than food hygiene recognition.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"11 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478664","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 subjects were 348 male workers and data collection was conducted in February 2023 using a self-administered questionnaire. The results of regression analysis verifying the mediating effect of social support in the relationship between job stress and turnover intention of the survey subjects showed that the higher the job stress, the lower the social support (F=62.17, p<0.01), and the higher the turnover intention (F=57.71, p<0.01). The effect of social support on turnover intention while controlling job stress was also statistically significant (F=46.53, p<0.01). As the job stress β value was 0.353, which was smaller than the β value of 0.508, which was not passed through the parameter, it could be concluded that social support had a mediating effect. In the Sobel test results, social support played a partial mediating role in the relationship between job stress and turnover intention (Z=-4.26, p<0.01). The above results suggest that social support for male workers in the manufacturing industry may have a mediating effect on reducing job stress related to turnover intention.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"57 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478599","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}

It is currently implemented in the U.S., Japan, and some ships of the Korean Coast Guard. Despite the advantage of improving the operation rate of a ship while reducing crew fatigue, only conceptual studies have been conducted by the Korean Navy. This study used simulations to compare the mission completion rate, shipload ratios, and crew load ratios before and after applying the crew rotation system. The target of the research was a Chungmugong Yi Sun-sin class ship, one of the main battleships of the Korean Navy, which is also assigned to many overseas missions, such as the Cheonghae unit dispatchment, and midshipmen cruise training. The application of a crew rotation system had no side effects in completing the assigned mission. In addition, the shipload and crew load ratios decreased in the number of days of mission performance by 33 days and 42-47 days, respectively. Furthermore, applying the system ensures the resting conditions for crew members and reduces crew fatigue while securing training periods to maintain stable education and training. As a result, it is expected that mission performance will be improved. On the other hand, the crew rotation system goes against the Navy's culture of the crew having a strong bond of fate with their ship. Nevertheless, the actual implementation of the system is difficult considering problems, such as ship maintenance must be transferred to a dedicated repair department on land and the extensive cost required to expand the dedicated facilities and personnel. This study is meaningful because stimulations were used to provide the framework for the quantitative results required to establish related policies in the future.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"276 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475998","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}

To this end, complex HW and SW that can increase the system processing speed and support wide frequency bandwidth are essential. In particular, with the advent of the 5G communication market, the size and complexity of SW have increased significantly because HW, which supports various frequency bands, requires SW that supports various functions. In addition, there are cases where new functions must be provided only by an SW upgrade without a HW change, making SW quality assurance more critical. In this study, only the Waterfall method was used when developing mobile communication equipment SW, as a market quality stability issue due to the nature of communication equipment, even if it took longer. On the other hand, a new Hybrid Agile-K model that can improve chronic market problems simultaneously was presented along with repetitive and gradual model presentation using the advantages of Waterfall and Agile models to change new communication protocols, such as 5G, and respond to customers' rapid market demands.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"252 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140473667","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}

This study conducted research to establish a shared system for accumulating and expanding data, aiming to secure an ample library throughout the life cycle. The research was conducted in three directions: the development of design libraries, the configuration of open properties, and the establishment of an expandable shared system. The design library, based on railway standards, analyzed the quantity and information of useful objects, resulting in the development of 741 items suitable for the design phase with a LoD 300. The properties of the libraries were configured in an open format to operate in the sharing system, providing design-specific parameters and information reflective of design details. In particular, the sharing system was established with an expandable concept, integrated with the delivery system to allow for the addition of new data, expanding the objects within the existing data bank. Initially, the facility classification system PBS was integrated with railway standard codes. Considering the WBS and ISO system to enable stepwise expansion throughout the lifecycle, a sequential numbering system was implemented in an expandable format. Designing data management properties to prevent duplication and loss of data, a database for the delivery system was developed. A program was written and implemented to enable search, sharing, and additional expansion. The scalable shared system and open design libraries will contribute to consistent information management and library augmentation throughout the design, construction, and maintenance lifecycle.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140476268","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}
