This study investigated when TV drama producers choose famous actor/actress based on 288 TV dramas aired in Korea from January 2014 to December 2017. We considered the length of drama, measured by the number of episodes, as a major determinant for choosing famous actor/actress, as well as the existence of originals, use of independent producing agents, and producers' fame as interacting factors between length of drama and choosing famous actor/actress. We detected that drama length had a significant effect while original dramas had an interacting effect. We interpret this result as the effect of mismanagement of drama producing. While a famous actor/actress has the potential to provide economic gains to drama producers, drama producers should be careful in choosing him/her since his/her drama guarantee should be high. This is why producers should choose a famous actor/actress when the length of the drama is short and should prefer an original drama.

Recently, firms confront to rapid environmental changes due to scientific development and demand change. Firms are trying to improve supply chain capability to react these environmental changes. Being in these improvement processes, it is important to collaborate with other partners in the supply chain. Firms have tried to outsource their in-house activity to other partners and have eliminated wasteful factors in their process and the supply chain is getting leaner. This study investigates the effect of waste factor degree on supply chain performance under external risks. Test results in this paper show that waste level has negative relationship with supply chain performance. The effect of waste level on the supply chain performance is influenced by external risk. As waste level increases, risk has moderating effect between waste level and supply chain performance. That means it is important to focus on utilization, productivity or integration properly for managing the external risk in order to improve the supply chain performance.

This study aims to analyze the current status of library automation systems and explore future directions for improvement. The study was conducted by surveying librarians at institutions participating in the KESLI and KCUE consortia to investigate the current status and satisfaction with library automation systems, and the current status and awareness of open source-based library automation systems. The study found that most automation systems currently in use in libraries were developed through outsourcing in the 2000s or 2010s, and that more than 50% of respondents were satisfied with the overall library automation system. Overall satisfaction was found to be influenced by satisfaction with the functionality, customer support services and construction and operational management of the system. Most current library automation systems are not based on open source software or cloud services, but the intention to use them in the future is high, with more than 40% of respondents saying they would use them within three years. This study is expected to serve as an important foundation for building an open source-based library automation system in the future.

As the social acceptance of artificial intelligence increases, the number of cases of applying machine learning methods to companies is also increasing. Technical factors such as accuracy and interpretability have been the main criteria for selecting machine learning methods. However, the success of implementing machine learning also affects management factors such as IT departments, operation departments, leadership, and organizational culture. Unfortunately, there are few integrated studies that understand the success factors of machine learning selection in which technical and management factors are considered together. Therefore, the purpose of this paper is to propose and empirically analyze a technology-management integrated model that combines task-tech fit, IS Success Model theory, and John Rice's algorithm selection process model to understand machine learning selection within the company. As a result of a survey of 240 companies that implemented machine learning, it was found that the higher the algorithm quality and data quality, the higher the algorithm-problem fit was perceived. It was also verified that algorithm-problem fit had a significant impact on the organization's innovation and productivity. In addition, it was confirmed that outsourcing and management support had a positive impact on the quality of the machine learning system and organizational cultural factors such as data-driven management and motivation. Data-driven management and motivation were highly perceived in companies' performance.

Haeundae Doosan We've The Zenith project is adjacent to Suyoung-bay, now it is in the process of excavation and foundation work. The main use of the tower is residence which height is 300m and 80 floor, the highest residential reinforced concrete building through the Orient. It is comprised of 3 high- rised buildings and 1 low-rised building, the basement is 230m wide and 200m length sized mass structure. The lateral resistance system is acted effectively against the lateral load and satisfactorily against the wind vibration by the 4 direction extension of the center core wall($700{\sim}800mm$ thickness) and reinforced concrete column set around the slab. Flat-plate slab system(250mm thickness) is adjusted for the slab system and it enables effective work process and shortening the working term by minimizing the ceiling height and not needing to install perimeter beam and drop panel. The strength and serviceability of the structure is able to be monitored and estimated constantly through the health monitoring system during the construction and after the construction.

The objective of this study is to propose an automated algorithm for precise cutting length of slab rebar complying with regulations such as anchorage length, standard hooks, and lapping length. This algorithm aims to improve the traditional manual quantity take-off process typically outsourced by external contractors. By providing accurate rebar quantity data at BBS(Bar Bending Schedule) level from the bidding phase, uncertainty in quantity take-off can be eliminated and reliance on out-sourcing reduced. In addition, the algorithm allows for early determination of precise quantities, enabling construction firms to preapre competitive and optimized bids, leading to increased profit margins during contract negotiations. The proposed algorithm not only streamlines redundant tasks across various processes, including estimating, budgeting, and BBS generation but also offers flexibility in handling post-contract structural drawing changes. In particular, the proposed algorithm, when combined with BIM, can solve the technical problems of using BIM in the early phases of construction, and the algorithm's formulas and shape codes that built as REVIT-based family files, can help saving time and manpower.

Microflora and contamination process of Saengshik products were investigated to ensure microbial safety of Saengshik. Food-borne pathogenic bacteria, such as Staphylococcus aureus, Bacillus cereus, and Clostridium perfringens detected mainly from grains were not removed by washing with tap water and freeze-drying. Contaminations of food-borne pathogenic bacteria occurred through raw material powder processed at other factories and during actual product manufacturing process, because detection rates of final products were higher than those of raw materials. Concentration of food-borne pathogenic bacteria increased with advancing of process after first pulverization. Dusts of powder and powder attached to machine were good media for air-borne microorganisms and caused to increase of food-borne pathogenic bacteria during process. Improvement of manufacturing process and sanitary control of machines arc necessary to ensure microbial safety of Saengshik.

In this study, we wanted to analyze the causes of food poisoning and its major occurrence in September 2018 and analyze the relevance of the HACCP certification system to report the correlation. Based on three-year food poisoning cases and causative substances data, and big data on HACCP certification companies and food poisoning frequency, Hygiene 1: 'Salmonella would have spread through school food processing medium.' Hypothesis 2: The difference in the number of food poisoning cases in the last three years as the number of HACCP certifier increases, the number of food poisoning cases will be verified and the cause of food poisoning in September 2018. Studies show that the food poisoning in September 2018 was caused by salmonella bacteria and that outsourced food provided through school meals was the cause. It was also shown that the expansion of HACCP certification did not significantly contribute to the reduction of food poisoning. Therefore, the management operation measures were proposed as a solution to prevent salmonella and to become HACCP certification that could reduce food poisoning.
