The increase in inflow causes a discharge exceeding the storage and spillway capacity of reservoirs. Discharge exceeding the capacity of the structure induces overtopping, a dominant cause of levee collapse. Various reinforcement methods were applied to increase the stability of the levee. The installation of levee reinforcement is one of the methods to increase the stability of the levee. A study on the reinforcement installation is necessary to evaluate the delay effect of collapse with respect to the reinforcement and its arrangement. In this study, physical experiments were conducted to evaluate the delay effect of collapse with respect to the reinforcement. For the experiment, a soil embankment was constructed in a water tank. A constant discharge was supplied to the embankment, and a spillway was constructed to induce overtopping. Reinforcements were placed on the levee to compare the time for collapse and reaching the collapse stage according to the reinforcement arrangement. As a result, the embankment with reinforcement required more time to collapse than that without. The optimal arrangement of reinforcement was determined by comparing the difference in the collapse depth and stage over time.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"230 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475236","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 2016, the World Health Organization reported that more than three million people die early every year due to fine dust. Korea is one of the countries with lower air quality and needs to take measures against increasing fine dust concentrations. The government has provided fine dust concentration data from all regions to solve this problem. On the other hand, it is unclear if the data currently provided reflects the \"average\" fine dust concentration in each region, and efficient management according to the new database (DB) model is required in the case of vast amounts of data. This study analyzed the concentration of fine dust by region on a monthly average basis. The paper presents a method for managing fine dust data using a new DB model. It also introduces data preprocessing techniques accordingly. Map visualization is performed using preprocessed data, and techniques are introduced. The DB model, fine dust data preprocessing technique, and visualization technique presented in this paper are expected to be useful in providing various fine dust-related services in the future.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"454 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140471332","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 focuses on improving the performance of the existing Plenum-type airflow system with a new ventilation flow research model. The new research model simplifies the shape of the airflow path compared to the existing product, reducing air turbulence during flow. Simultaneously, embossing is applied to the lower surface of the airflow path to generate a swirling motion of mixed air inside, achieving a uniform airflow velocity at each ventilation outlet. The existing product and the research model were designed, and fluid dynamics analysis was conducted to validate the performance improvement of the improved research model. Prototypes were also manufactured and subjected to performance evaluation tests. Fluid dynamics analysis showed that the average airflow velocity at the ventilation outlets was 2.88 m/s for the existing product, whereas the research model achieved an average velocity of 6.22 m/s, representing an approximate 116 % improvement in performance compared to the existing product. Furthermore, the uniformity of airflow velocity was enhanced by approximately 195 %. The performance testing results indicated that the existing product exhibited an average airflow velocity of 2.76 m/s, whereas the research model demonstrated an average velocity of 5.41 m/s, resulting in 96.01 % performance improvement.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"9 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140479091","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}

Electrical properties were imparted to cotton through a dip-and-dry process employing silver nanowires, which exhibit high electrical and thermal conductivity. The investigation examined variations in thermal and electrical characteristics based on concentration and the number of dip-and-dry cycles. As the cycle count increased and the concentration of Ag nanowires rose, a noticeable decrease in specimen resistance was observed. When an external voltage was applied, the current-voltage relation was shown to be linear indicating the structure follow the ohm’s law. Further, in line with the Joule heating mechanism, temperature increased proportionally with higher applied voltages, confirming the relationship between heating temperature and current. To assess the stability and reproducibility, voltage application and removal were repeatedly executed, which resulted in temperature deviations within ±2°C of the average temperature. Uniform heating characteristics were consistently observed, even when the specimen was heated on curved surfaces, such as a person's shoulder.","PeriodicalId":112431,"journal":{"name":"Journal of the Korea Academia-Industrial cooperation Society","volume":"96 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140476360","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}
