Laser cladding technology was studied as a method for upgrading the present repair procedures of damaged tubes in a nuclear steam generator and Doosan subsequently developed and designed a new Laser Cladding Repair System. One of the important features of this newly developed Laser Cladding Repair System is that molten metal can be deposited on damaged tube surfaces using a laser beam and filler wire without the need to install sleeves inside the tube. Laser cladding qualification tests on the steam generator tube material, Alloy 600, were performed according to ASME Section IX.

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.

The research is intended to satisfy two interesting research purposes: one is to examine activities of both BSC adotion phase and implementation phase under carrying BSC project. The second purpose is to analyze the influence from those activities towards innovating business world. This study was conducted thru online questionnaires via online survey system during 3 months for targeting mainly on business users and consultants. The findings of the study suggest that employee's involvement, BSC information sharing, collaboration cross task related teams have major roles to operate BSC successfully. From findings, KPI choice, top-down goal allocation, budgeting allocation have strong influences on upgrading business innovations. Those businesses like to considering adoption of BSC can benefit from the findings of the research.

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.

본 연구는 현재 운영되고 있는 광역 보조기구센터의 공적급여 연계 현황을 분석하고 발전 방향을 제시하는데 목적이 있다. 이를 위해 각 보조기구센터가 공적급여 사업에서 연계하고 있는 서비스 단계 및 주요 연계 부분들을 파악하였고, 지역사회에서 실시하고 있는 수리사업의 현황과 연계 현황 그리고 각 서비스에 필요한 공급 업체 연계에 대한 현황을 조사하였다. 이를 통해 나타난 결과는 공적급여는 보조기구 정보제공 수준에서의 연계가 가장 많았다. 수리사업은 모든 센터들이 실시하지만 경 정비 수준의 수리를 일반적으로 수행하였고, 지역사회 전문 수리 업체와 연계하여 서비스를 제공하는 실정이었다. 공급 업체 연계는 지역별로 차이가 많이 나타났다. 이를 통해 전문센터에 보다 다양한 보조기구의 확충을 통한 공적급여 정보제공의 질적 향상과 지속적인 공적급여 지원 기관과의 긴밀한 교류가 필요하며, 연계의 효과성을 분석하여 정책 수립의 근거를 확보할 필요가 있다.

우리나라는 글로벌 기술경쟁력 제고를 위해 연구개발에 대한 투자를 지속적으로 증대시켜왔다. 우리나라의 GDP대비 연구개발투자비는 4.15%로 세계 1위 수준이며, 이 가운데 기업부문은 전체 투자의 78.5%를 차지하며 매우 중요한 역할을 수행하고 있다. 그러나 더 이상 양적인 투자 증대에는 한계가 존재하기에 R&D투자에 대한 질적 수준을 높여 효율성을 제고하기 위한 노력이 절실히 필요한 실정이다. 이러한 연유로 본 연구에서는 기업의 경영성과를 제고하기 위한 방안을 강구하기 위한 연구를 수행하였다. 이를 위해 그동안 학문적으로 그 중요성이 강조된 연구개발 초기 단계인 기술전략과 기술기획 역량이 기업의 성과제고에 미치는 영향요인을 실증적으로 검증하고자 하였다. 실증분석 결과, 기술전략과 기술기획 활동이 경영성과 제고에 매우 유의미한 영향을 미치는 것으로 나타났으며, 조직유연성의 경우 개별적인 요인 또한 중요하지만 기술기획 활동을 긍정적으로 조절하여 경영성과 제고에 기여함을 확인하였다. 본 연구에서는 기업의 기술혁신 활동을 실제적으로 파악하기 위해 기업연구소를 운영하고 있는 전체 기업을 대상으로 표본조사를 수행하였으며, 분석방법으로는 다중회귀분석과 분위회귀분석을 활용하였다.
