In today's business landscape, collaboration and interoperability are crucial for organizational success and profitability. However, integrating operations across multiple organizations is challenging due to differing roles and policies in Identity and Access Management (IAM). User-centric identity (UCI) adopts a personalized approach to digital identity management, centering on the end-user for authentication and access control. It provides a decentralized system that ensures secure and customized access for each user. UCI aims to address complex security challenges by aligning access privileges with individual user requirements. This research delves into UCI's ability to streamline resource access amidst conflicting IAM roles and protocols across various organizations. The study presents a UCI-based multi-domain access control (MDAC) framework, which encompasses an ontology, a unified method for articulating access roles and policies across domains, and software services melding with UCI infrastructure. The goal is to enhance organizational resource management and decision-making by offering clear guidelines on access roles and policy management across diverse domains, ultimately boosting companies' return on investment.

Study results on the perception of organization justice and organization member behavior of private security are as below. Primarily, organization justice showed variation according to socio-demographic characteristics which include age, the period the person has stayed in the current workplace, total period of working and monthly income. As for age, in aspect of the perception of distribution justice, the 36 or older age group prevailed, and the 31 to 35 age group prevailed in the perception of procedure justice. So, perception of organization justice increased accordingly with age. According to the period the person has stayed in the current workplace category, showed high levels in the perception of distribution justice and perception of procedure justice in the $3\;{\sim}\;5$ years group. As for total period of working, both perception of distribution justice and the perception of procedure justice proved greatest in the 5 years or more group and according to monthly income, the KRW 1800,000 or more group showed high levels of perception of distribution justice and the perception of procedure justice. Secondly, organization member behavior showed variation according to sociodemographic characteristics. In organization member behavior, loyal behavior increased along with age and inter-personal relationship behavior and altruistic behavior prevailed in the age group 31-35 According to period the person has worked at the current workplace and in case of total period of working, loyal behavior, inter-personal relationship behavior and altruistic behavior proved to be high. As for monthly income, an increase in monthly income resulted in a high figure in loyal behavior, inter-personal relationship behavior and altruistic behavior. Thirdly, after regression analysis of the relationship of the perception of organization justice and organization member behavior, perception of procedure justice was analyzed to have relatively high influence. Therefore, the hypothesis presented in this study was all chosen after the regression analysis results. This shows that the enhancement of organization member behavior can be improved. by enhancing the perception of organization justice. Thus, it can be concluded that if a private guard recognizes his justice, organization member behavior can be enhanced.

Buffer solubility and protein fractionation were evaluated from the hays (timothy, alfalfa and klein) and straws (tall fescue and rice), and $In$ $vitro$ trial was conducted to examine the effect of buffer extraction on fermentation characteristics, degradability and gas ($CO_2$ and $CH_4$) production. Buffer soluble protein (SP) content and A fraction in total protein were highest in alfalfa hay as 61% and 41.77%, respectively while lowest in rice straw (42.8% and 19.78%, respectively). No difference was observed in B1 fraction among forages but B2 fraction was slightly increased in klein hay (12.34%) and tall fescue straw (10.05%) compared with other forages (6.34~8.85%). B3 fraction of tall fescue was highest as 38.49% without difference among other forages while C fraction was highest in rice straw. pH in incubation solution was higher in all forages after extraction than before extraction at 3h (P<0.01) and 6h (P<0.05), and pH from hays of timothy and alfalfa was higher than the other forages at 6h (P<0.05) and 12h (P<0.001). Regardless of extraction, ammonia-N concentration from alfalfa hay was increased at all incubation times and extraction effect was appeared only at 3h incubation time (P<0.01). Total VFA concentration from alfalfa hay was highest up to 24h incubation while those from tall fescue straw and rice straw were lowest. Buffer extraction decreased (P<0.01~P<0.001) the total VFA concentration. Acetic acid proportion was increased (P<0.001) before extraction of forages but no difference was found between forages. Propionic acid($C_3$) proportion was also increased(P<0.001) before extraction in all forages than in straws at 3h, 24h and 48h incubations, and $C_3$ from hays were mostly higher (P<0.05) than from straws. Butyric acid proportion, however, was not affected by extraction at most incubation times. Parameter 'a' regarding to the dry matter (DM) degradation was increase (P<0.001) in all forages before extraction, and was decreased (P<0.05) in tall fescue straw and rice straw compared with hays. Parameter 'b' was also increased (P<0.001) before extraction but no difference was found between forages. Effective degradability of DM (EDDM) was higher (P<0.001) before extraction in most forages except for rice straw. Buffer extraction decreased (P<0.05) all parameters (a, b, and c) regrading to the crude protein (CP) degradation but no difference was found between forages. Effective degradation of CP (EDCP) was lower (P<0.05) in straws than in hays. Parameters 'a' and 'b' regarding to the NDF degradation (P<0.01) and effective degradability of NDF (EDNDF, P<0.001) were also higher in forages before extraction than after extraction but no difference was found between forages. Buffer extraction reduced (P<0.05~P<0.001) $CO_2$ production from all the forages uo to 24h incubation and its production was greater (P<0.05~P<0.01) from hays than straws. Methane ($CH_4$) production was also greater (P<0.01~P<0.001) in all forages at all incubation times, and its production was greater (P<0.05) from hays than from straws at most incubation times. Based on the results of the current study, it can be concluded that buffer solubility and CP fractionation might be closely related with $In$ $vitro$ VFA concentration, degradability and gas ($CO_2$ and $CH_4$) production. Thus, measurement of buffer solubility and protein fractionation of forages might be useful to improve TMR availability in the ruminants.

This study was conducted to investigate the quality characteristics and antioxidant activities of jelly prepared with different amounts of aronia juice. Aronia juice was incorporated into jelly at concentrations of 3, 6, and 9%, based on the total weight of water. While the total water content of the jelly in different groups was not significantly different, the sugar content significantly increased with increasing levels of aronia juice. In the chromaticity measurements, $L^*$ and $b^*$ values decreased, whereas the $a^*$ values increased with increasing levels of aronia juice in the jelly. Further, the hardness and chewiness of jelly increased with increasing amounts of aronia juice. On the other hand, resilience, cohesiveness, and gumminess of the jelly were nearly similar for the control and samples treated with aronia juice. The total polyphenols, flavonoids, and anthocyanin contents increased proportionally with increasing levels of aronia juice. In addition, the antioxidant activity measured in terms of the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activities of the jelly extracts were significantly higher for the samples containing aronia juice compared to the control and increased proportionally with increasing concentrations of aronia juice. In the sensory evaluation, the sample containing 6% aronia juice was perceived to have the best color, taste, texture, chewiness, flavor, and overall acceptance. These results suggest that aronia juice may be a useful ingredient in jelly for improving its quality as well as sensory and antioxidant potential.

The purpose of this research is to achieve qualitative growth for private security industry as a sector of service industry to attract clients and promote the growth of the private security industry by analyzing the factors which influence the customer's service satisfaction in using the private security services. A regression analysis was conducted to determine the factors which influences the satisfaction of private security service to ultimately achieve the research purpose. In the regression analysis, the difference between corporate clients and individual clients were analyzed for the sake of providing better security services and marketing applications. As a result, the factors that influences the satisfaction of the categorized groups were very clearly signified. Both individual and corporate clients showed increase in satisfaction rate when the fear of crime decreased. This result implies that the private security firms must possess segmented strategies as well as strategies to lower the fear factors of clients. There were no differences in all satisfaction-influencing factors when the fear reduction variable was exempted among both corporate and individual clients in usage satisfaction. This result shows that clients demand varies according to the client and the security firms must react to these demands by the clients. Although private security industry possess very clear publicity, it is a profit generating industry sector therefore, like other service industry, the private security services must implement strategies to keep up with the paradigm. If the satisfaction determinants from the research results are grafted into strategies such relationship marketing and target market selection, higher service satisfaction can be achieved from the clients.
