Computer architecture serves as a link between application requirements and underlying technology capabilities such as technical, mathematical, medical, and business applications' computational and storage demands are constantly increasing. Machine learning these days grown and used in many fields and it performed better than traditional computing in applications that need to be implemented by using mathematical algorithms. A mathematical algorithm requires more extensive and quicker calculations, higher computer architecture specification, and takes longer execution time. Therefore, there is a need to improve the use of computer hardware such as CPU, memory, etc. optimization has a main role to reduce the execution time and improve the utilization of computer recourses. And for the importance of execution time in implementing machine learning supervised module linear regression, in this paper we focus on optimizing machine learning algorithms, for this purpose we write a (Diabetes prediction program) and applying on it a Practical Swarm Optimization (PSO) to reduce the execution time and improve the utilization of computer resources. Finally, a massive improvement in execution time were observed.

This study investigates the interplay between transformational leadership, personality, and work stress in public organizations, focusing on public servants in Putrajaya, Kuala Lumpur. Data from 702 public servants in Putrajaya, Kuala Lumpur, out of 800 distributed questionnaires, were analyzed. Rigorous analysis employed a structural equation model (SEM) with partial least squares (PLS-SEM) methodology. Our empirical analysis challenges the conventional belief of a positive correlation between transformational leadership and work stress in public organizations, revealing no direct link between transformational leadership and increased work stress in this context. Our study highlights a significant positive correlation between personality and work stress among public servants, emphasizing the role of individual personality characteristics in shaping work-related stress levels. Finally, personality emerged as a crucial mediator in the transformational leadership-work stress relationship, indicating that transformational leadership indirectly influences work stress through its impact on personality. This underscores the importance of considering personality as a mediating factor in understanding the transformational leadership-work stress dynamic in public organizations. In summary, our research provides insights into the relationship between transformational leadership, personality, and work stress in public organizations. These findings challenge conventional assumptions, emphasize individual differences in stress levels, and underscore the mediating role of personality in addressing work stress among public servants.

Construction management performs a variety of tasks, and the buildup of the WBS and OBS is one of the core tasks. However, the practical utilization of WBS and OBS is low in the current construction management work. In this study, we conducted a survey of related experts to analyze the understanding, utilization level, application effect, and connectivity of WBS and OBS. As a result, it was identify that the standardization and linkage of WBS and OBS should be secured so that the construction manager (CMr) could apply it. Therefore, we extracted management control factors through expert in-depth interviews and workshops and conducted AHP importance analysis. Analysis results of importance shows that there is a high importance of strengthening the link between WBS and OBS and updating OBS due to changes in WBS. The results presented are not direct solutions, but are expected to provide a standard for construction managers to consider.

There has been growing social interest recently in the movement rights of people with reduced mobility. However, it simply eliminates the temporary inconvenience of walking of people with reduced mobility because it focuses only on supply of institutional facilities. Therefore, we look forward to improving movement welfare by proposing an optimized path finding algorithm for people with reduced mobility that takes into consideration physical elements affecting their movement, such as slope, steps etc. We selected Walking barrier factor by analyzing previous studies and calculated the relative importance of Walking barrier factors using an Analytic Hierarchy Process(AHP). Next, through the fuzzy system, the Walking disturbance level of link, which integrates the weights of Walking barrier factors and the attributes of each link, is derived. Then, Walking path cost that takes into consideration the ‘length’ factors is calculated and an optimized path for people with reduced mobility is searched using Dijkstra’s Algorithm. Nineteen different paths were searched and we confirmed that the derived paths are meaningful in terms of improving the mobility of people with reduced mobility by conducting a field test. We look forward to improving movement welfare by providing a navigation service using the path finding algorithm proposed in this study.

Past corporaion's network security system is single security solution, or mixed several ways, but there was inefficient system because doing not get into organic link But, constructed more strong security system by ESM enterance on. ESM uses way to integrate of each agent to manage easily various kinds security solution. That is, it is system that connect system of existent VPN, FireWall, IDS and so on configurationally depending on security policy and manage. ESM is security system that is developed more than existent security system. But, practical use of network and the development speed of technology being increasing with the mon faster speed, is heightening the level more as well as dysfunction of information crime and so on. Many improvements are required at ESM system, this research wished to make up for the weak-point in the ESM system about interior security. Studied on structure of security solution that is basis of security policy. VPN, Firewall, IDS's link that is main composition of existing security system analysis, reconstructed.

In the context of an increased demand in universities' expansion of networks between other innovation actors, this research attempts to make a comparison on university-centered SCIE knowledge networks between regions. Using regional comparison, we have looked into these networks in regards to their characteristics, the importance of regional boundaries, and the effect of the regional industrial policy. As a result of this comparative analysis, we discovered that the point universities and research universities hold high centrality in regional knowledge networks, and that the characteristics of regions are reflected into this network. For instance, the Gyeonggi province had a preeminent level of industry-academy relationship, while for Daejeon it was public research institutions and academy, and Gangwon province it was between academy between academy. As a network analysis based on journals above SCIE levels, regional boundaries were not very clear in the network structures. However, within these boundaries, the impact of regional industrial policies were proven to be stronger in the Gang-won province where the academy-academy network was most prominent. The implication of this research outcome is that for regional innovation, government should more actively implement policies that can link academic institutes' knowledge to industry by expanding knowledge networks. In addition, we emphasize on the necessity of a regionally-appropriate policy, rather than a generalized industrial policy. And fundamentally, in regards to innovation, establishing a sound industrial infrastructure for regional development and efforts to link relevant actors are required.

Technology cooperation is a necessary factor for small and medium sized firms to be survived and developed because small and medium sized firms can make economy scale and economy scope by new advanced technologies obtained from technology cooperation. Therefore, the technology cooperation of small and medium sized firms can be thought as their specific resource. Due to the importance of technology cooperation, many previous studies paid an attention on its positive effect. Unlike the related studies, this study examined the link among uncertainty of technology environment, relationship characteristics(such as degree of technology cooperation and influential strategy), and relationship tie. The empirical results are reported as follows: Firstly, uncertainty of technology environment positively affected on degree of technology cooperation. Secondly, degree of technology cooperation positively affected on uncoercive influential strategies of both own firm and partner firm. Thirdly, degree of technology cooperation and uncoercive influential strategy of own firm have positive effects on relationship tie while uncoercive influential strategy of partner firm does not. The positive effect of uncoercive influential strategy of own firm means the importance of strategic countermeasures to promote relationship tie in technology cooperation of both own firm and partner firm.
