This paper will discuss the significance of cooperation between supply chain companies and its components. In addition, it will analyze how this effects the outcome in distribution focusing on companies in the steel pipe industry. In sum, theory 1 was chosen since as a result of hierarchical regression analysis communication, IT, partnership, and success monitoring, which are all components of the supply chain cooperation, are proven to affect the absolute distribution success positively. According to the standardized beta coefficient the most important factor for distribution success is communication, followed by IT, partnership and lastly success monitoring. Moreover, according to theory 2, communication, IT, partnership and success monitoring all affect relative distribution success positively. Most important factors are communication, IT, partnership, success monitoring. Thus, since the most crucial factor in deciding both the absolute and relative distribution success is communication, steel pipe companies are advised to execute strategic use.

The aerobic respiratory chain of Vibrio alginolyticus possesses two different kinds of NADH oxidase systems, i.e., an $Na^{+}$-dependent NADH oxidase system and an $Na^{+}$-independent NADH oxidase system. When deamino-NADH, which is the only substrate for the $Na^{+}$-dependent NADH oxidase system, was used as a substrate, the maximum activities of $N^{+}$-dependent NADH: quinone oxidoreductase and $Na^{+}$-dependent NADH oxidase were obtained at about 0.06 M and 0.2 M NaCl, respectively. When NADH, which is a substrate for both $Na^{+}$-dependent and $Na^{+}$-independent NADH oxidase systems was used as a substrate, the NADH oxidase activity had a pH optimum at about 8.0. In cGntrastl when deamino-NADH was used as a substrate, the NADH oxidase activity had a pH optimum at about 9.0. On the other handle inside-out membrane vesicles prepared from the wild-type bacterium generated only a very small $\Delta$pH by the NADH oxidase system, whereas inside-out membrane vesicles prepared from Napl, which is a mutant defective in the $Na^{+}$ pump, generated $\Delta$pH to a considerable extent by the NADH oxidase system. On the basis of the results\ulcorner it was concluded that the respiratory chain-linked components of V. atginotyticus affect each other.

The amino acids found in plants play important roles in protein biosynthesis, signaling processes, and stress responses, and as components in other biosynthesis pathways. Amino acid degradation helps maintain plant cells' energy states under certain carbon starvation conditions. Branched-chain amino acid transferases (BCATs) play an essential role in the metabolism of branched-chain amino acids (BCAAs) such as isoleucine, leucine and valine. In this paper, we performed genome-wide RNA-seq analysis using CsBCAT7-overexpressing Arabidopsis plants. We observed significant changes in genes related to flowering time and genes that are germination-responsive in transgenic plants. RNA-seq and RT-qPCR analyses revealed that the expression levels of some BCAA catabolic genes were upregulated in these same transgenic plants, and that this correlated with a delay in their senescence phenotype when the plants were placed in extended darkness conditions. These results suggest a connection between BCAT and the genes implicated in BCAA catabolism.

Blending Is cheap and leads to new thermoplastics, many properties which can be predicted from those of the components. Due to the incompatibility of their components, most blends feature coarse phase morphologies with weak interfaces between the phases. Consequently the blends are brittle. Thermoplastic elastomers which have two kinds of segments in the chain have flexible(soft) and rigid(hard) segments and exhibit a unique combination of strength, flexibility, and processibility.

The purpose of this study is to explore the nature of supply chain partnership, and to find the factors influencing the supply chain partnership success. For this, relationship commitment and trust were used as the basic components of the supply chain partnership. Also we identified strategic fit, interdependence, compatibility, and communication as determinants of supply chain partnership. Based on the statistical analysis of the sample of Korean corporations, it was found that relationship commitment and trust were shown to be significant factors influencing the supply chain partnership success. In addition, the findings reveal that strategic fit, interdependence, compatibility, and communication will facilitate supply chain partnership. More specifically, strategic fit and interdependence have a significant positive influence on relationship commitment. Also, compatibility and communication have a significant positive influence on trust. There result, in short, supported the importance of supply chain partnership for the successful SCM.

Recently, research on solving problems that have introduced the concept of smart city in countries and companies around the world is in progress due to various urban problems. A smart city converges the city's ICT, connects all the city's components with a network, collects and delivers data, and consists of a supply chain composed of various IoT products and services. The increase in various cyber security threats and supply chain threats in smart cities is inevitable, in addition to establishing a framework such as supply chain security policy, authentication of each data provider and service according to data linkage and appropriate access control are required in a Zero-Trust point of view. To this end, a smart city security model has been developed for smart city security threats in Korea, but security requirements related to supply chain security and zero trust are insufficient. This paper examines overseas smart city security trends, presents international standard security requirements related to ISMS-P and supply chain security, as well as security requirements for applying zero trust related technologies to domestic smart city security models.

This study shows the operational availability(Ao) analysis of the supply chain with maintenance functions using the system dynamics simulation. The simulation uses 60 equipments which are serial systems composed by 4 major components. And every entities are connected each other by causal loops. So whole simulation executed like one organic system. Specially we consider 2 constraints, one is the number of spare parts and the other is maintenance capacity level. 2 constraints have 11 levels each so the simulation has 121(11*11) scenarios which scenario has 30 different random number seed. The simulation executed total 3,630(11*11*30) times. We analysis average Ao of total equipments by 121 scenarios and additionally the regression of the average Ao and 2 constraints. As the result, we can get the more accurate values by the system dynamics simulation than the regression to analysis complex system like the supply chain with maintenance functions.

Recently, the Malaysian government had been developing new technologies to the construction industry and one of them is the Industrialised Building System (IBS). The government urged that IBS is 100% utilized in all construction projects. It is believed that the application of IBS helps in reducing construction duration and cost, solving the problems of overflow of foreign workers in the site and improving performance and appearance of a structure. However, there are some parties like the contractor who feel reluctant to utilize this system because there are risks. They worry that their trades will be affected as IBS construct a structure using components which are manufactured in a factory and assemble on site. Therefore, this research is to find out whether IBS benefits the country's economy by focusing on the business created by investing in IBS. A comprehensive supply chain for IBS will be developed to compare with the traditional construction supply chain as to determine businesses or trades created and eliminated. This paper is looking at the theoretical framework about business opportunities due to the Government policy on embarking IBS.
