Many enterprises have implemented packaged enterprise resource planning (ERP) solutions rather than system development on the promises of feasible strategic benefits. Typical feasible benefits include adoption of global standards and processes through a proven integrated system, continuous version upgrading by vendors, and thus the easiness of system maintenance. The objectives of this research are to identify what makes a post-implementation success of ERP system and to figure out the critical issues and factors for the successful upgrade of packaged ERP systems. This case study was conducted based on five different organizations that have experienced system upgrade implementation. Success factors of ERP system upgrade include (1) clear statement of upgrade goals, (2) good coordination and communication among the implementation partners, (3) thorough management of customization and maintenance history including documentation, (4) Planning of system requirements of higher version, and (5) redefinition of role between business departments and IT department.

Indigenous innovation is the main strategy for China during 2006 - 20 period. China may hope that indigenous innovation policy will spur on industrial upgrading. The purpose of this paper is to evaluate the indigenous innovation policy. The paper begins with the background of the strategy, follows the detailed content of the national strategy, then analyzes how the strategy is implemented. We find that the package of indigenous innovation policy is constructive and efficient for a catch-up economy with clear industry targets but not good for innovation. If China want to be an innovative country, it needs to give market competition more space to incubate and eventually yield increment or disruptive innovation, even radical innovation. Chinese enterprises cannot close themselves off to the global technology system. Only open innovation can give Chinese enterprises the possibility to win in the next wave of innovation in the world and make China an innovative country.

The main objective of this study is to analytically investigate the effectiveness of different strengthening solutions in upgrading the seismic performance of existing reinforced concrete (RC) buildings in Nepal. For this, four building models with different structural configurations and detailing were considered. Three possible rehabilitation solutions were studied, namely: (a) RC shear wall, (b) steel bracing, and (c) RC jacketing for all of the studied buildings. A numerical analysis was conducted with adaptive pushover and dynamic time history analysis. Seismic performance enhancement of the studied buildings was evaluated in terms of demand capacity ratio of the RC elements, capacity curve, inter-storey drift, energy dissipation capacity and moment curvature demand of the structures. Finally, the seismic safety assessment was performed based on standard drift limits, showing that retrofitting solutions significantly improved the seismic performance of existing buildings in Nepal.

To make filler loaded conducting rubber which has the excellent electronical and physical properties, CR and NBR were mixed with magnetite$(Fe_3O_4)$. From the result of the study, vulcanization characteristics shows the upgrading curve as increase in filler concentration and CR has more torque than NBR. When elongation be higher, modulus comes to decreases. Tear strength gradually decrease after showing of the maximum point when is in the 100phr in all. Resilience is not good to cause the increase in filler concentration. In the electrical properties, conductivity becomes smaller when filler concentration is increased. The increase of voltage makes an conductivity grown, but the changed rate is weak. The influence of temperature hardly changes on increasing temperature. The morphology and the distribution for a conductivity filler through SEM were better, the more filler concentration increase, the shorter the particle interval is.

High performance sandcretes (HPS) are new concretes characterized by particles having a diameter less than 5 mm, as well as very high mechanical strength and durability. This work consists in finding solutions to make sandcretes with good physico-mechanical and durability properties for this new generation of micro-concrete. However, upgrading ordinary sandcrete into high performance sandcrete (HPS) requires a thorough study of formulation parameters (equivalent water/binder ratio, type of cement and its dosage, kind and amount of super plasticizer, and gravel/sand ratio). This research study concerns the formulation, characterization and durability, in a sulphate environment, of a high performance sandcrete (HPS), made from local materials. The obtained results show that the rheological properties of fresh concrete and mechanical strength differ with the mineralogy, density and grain size distribution of sands and silica fume used.

Kimchi industry in Korea has grown rapidly with the increasing domestic and overseas demand of Kimchi. Currently, there is an increase trend of consuming the commercial Kimchi products, although the Kimchi consumption/adult/year is decreasing (36.6 kg in 2018). The amount of commercial Kimchi consumption in 2018 was 757,000 M/T (metric ton), out of 1,892,000 M/T of the estimated total consumption, and the size of Kimchi market was estimated to be 1,398 billion wons. In 2019, 29,628 M/T of Kimchi was exported to 78 countries, and 306,047 M/T was imported, mainly from China. In the future, for the technological upgrading of Kimchi plants, a large capital investment to the production of commercial Kimchi will be required. The accelerated glocalization of Kimchi will bring a steady increase in Kimchi export. Moreover, with the development of global Kimchi culture, the values and images of Korean national brand can be greatly improved.
