The main purpose of this study is to develop a framework of knowledge management and knowledge management systems(KMS) for retail firms. The framework of knowledge management developed in this paper is based on six components: knowledge worker, KMS, leadership of CEO, knowledge management strategy, culture, evaluation and reward systems. The knowledge management process can be divided into four stages: preparation stage, initiation stage, expansion stage and completion stage. The major activities performed to implement effective knowledge management are also identified for each stage. The knowledge base of KMS for retail firms should store three types of knowledge: knowledge for management activity, knowledge for management activity, knowledge for strategic analysis, and knowledge for problem solving. Finally, the technical characteristics of KMS are also examined in terms of information technology.

Recently, research has been actively conducted to create artificial intelligence agents that learn games through reinforcement learning. There are several factors that determine performance when the agent learns a game, but using any of the activation functions is also an important factor. This paper compares and evaluates which activation function gets the best results if the agent learns the game through reinforcement learning in the 2D racing game environment. We built the agent using a reinforcement learning algorithm and a neural network. We evaluated the activation functions in the network by switching them together. We measured the reward, the output of the advantage function, and the output of the loss function while training and testing. As a result of performance evaluation, we found out the best activation function for the agent to learn the game. The difference between the best and the worst was 35.4%.

Reinforcement learning is an area of machine learning that studies how an intelligent agent takes actions in a given environment to maximize the cumulative reward. In this paper, we propose a new MAC protocol based on the Q-learning technique of reinforcement learning to improve the performance of the IEEE 802.11 wireless LAN CSMA/CA MAC protocol. Furthermore, the operation of each access point (AP) and station is proposed. The AP adjusts the value of the contention window (CW), which is the range for determining the backoff number of the station, according to the wireless traffic load. The station improves the performance by selecting an optimal backoff number with the lowest packet collision rate and the highest transmission success rate through Q-learning within the CW value transmitted from the AP. The result of the performance evaluation through computer simulations showed that the proposed scheme has a higher throughput than that of the existing CSMA/CA scheme.

Little attention has been focussed on a precise definition and evaluation mechanism for project management risk specifically related to contractors. When bidding, contractors traditionally price risks using unsystematic approaches. The high business failure rate our industry records may indicate that the current unsystematic mechanisms contractors use for building up contingencies may be inadequate. The reluctance of some contractors to include a price for risk in their tenders when bidding for work competitively may also not be a useful approach. Here, instead, we first define the meaning of contractor contingency, and then we develop a facile quantitative technique that contractors can use to estimate a price for project risk. This model will help contractors analyse their exposure to project risks; and also help them express the risk in monetary terms for management action. When bidding for work, they can decide how to allocate contingencies strategically in a way that balances risk and reward.

Despite heightened interest in and increased urgency surrounding the adoption of green business initiatives, firms seem to suffer from a limited understanding of the prerequisites and profit potentials of green strategies. Our proposed theoretical model suggests that green purchasing asa unique firmcapability must be built on internal organizational characteristics (i.e., top management commitment to environmental management, inter-functional coordination, and performance evaluation and reward systems), and that it eventually helps a firm obtain positive financial performance. We offer some research propositions about potential causal relationships among key constructs that can be empirically tested in future research. We conclude the current study with implications for both managers and researchers.

Main research question of this study is based on situational gap between donation motivation and behaviour in non-profit organization. However, researches investigating the gap were limited. Therefore, this study examined components of psychological variables. Specially, we proposed the variables about consumer's impulsive motivation or behavior on impulse literature in donation toward non-profit organization. This study conducted a scale development to measure consumer's charity donation impulse based on non-conscious viewpoint. For the development of measurement tool for charity donation impulse, we conducted two stages of research process. First, the measurement items of charity donation impulse were developed through FGI and in-depth interview on experts. Secondly, the factor analysis was performed, and then some items were eliminated through this analysis. As a result, we found the final scale with 26 items, which were named as evaluation sensitivity charity impulse, reward sensitivity charity impulse, functional impulse, non-planning charity impulse. These results showed that the measurement items developed in this study were confirmed to be useful tools for measuring charity donation impulse.

There is an inescapable requirement in public policy to provide evidence. For the evaluation of the EU Rural Development Policy, the European Commission has designed a Common Monitoring and Evaluation Framework(CMEF). The principal objectives of evaluations are to improve decision-making, resource allocation and accountability. In Korea, howerver, the opinion-based policy by expert is still rural development evaluation system. It does not provide the objective quantitative indicators for impact of rural development project. According to this, the budget-making body (parliament, government, etc.) have questioned the effectiveness of rural development projects, rural development projects often reduced or changed. To improve the accountability of rural development policy, it is necessary to build a reliable monitoring and evaluation system based on the evidence. First, rural development evaluation indicators should be considered the multipul goal of rural development, namely economic development, social development. Second, the purpose of the evaluation is necessary to be designed for the learning rather than reward. Third, the participation by local residents should be strengthened in evaluation process. Finally, it is necessary to establish rural development monitoring and evaluation system, such as CMEF of the EU (CMEF).

This paper provides a case for the comprehensive performance management system in Public Procurement Service. Public Procurement Service set up the BSC system at the beginning of 2006 by improving and complementing the earliest performance management system and made it possible to automatically connet the performance measurement and evaluation of the departmental and person by using CSF and KPI, which result from their mission and strategic assignments. Therefore, the public service of the adminstration is able to offer better customer service, as the private corporations do, apply the incentive and disincentive policies to the personnel and reward administration and contribute to changing the administration into an organization of competition and performance compensation. The application of the BSC system enables the strengthening of the individual evaluation system in the departmental, integration of various evaluations into one, and the establishment of a monitering system of achievement rate in the objective management in the periodic results. Such a case study of Public Procurement Service will determine the course of establishment of the BSC in other public institutions and suggest many successful methods and ideas for the performance management system.

Since the organization of civil servants has been divided and stratified according to the characteristics of the bureaucracy, it is inevitable that the organization and personnel will increase when new tasks arise. Even in the process of informatization, only the processing method was brought online while leaving the existing business processing procedures as they were, so there was no reduction in manpower through informatization. In order to maintain or upgrade the current administrative services while reducing the number of civil servants, it is inevitable to use AI technology. By using data and AI to integrate the 'powers and responsibilities assigned to the officials in charge', manpower can be reduced, and the reduced costs can be reinvested in the collection, analysis, and utilization of on-site data to further promote intelligent informatization. In this study, as a way for the government's success in intelligent informatization innovation, we proposed a 'Civil Servants-AI Collaboration Platform'. This Platform based on the civil servant proposal system as a reward system and the characteristics of intelligent informatization that are different from the informatization. By establishing a 'Civil Servants-AI Collaboration Platform', the performance evaluation system of the short-term evaluation method by superiors can be improved to a data-driven always-on evaluation method, thereby alleviating the rigid hierarchy of government organizations. In addition, through the operation of Collaboration Platform, it will become common to define and solve problems using data and AI, and the intelligence informatization of government organizations will be activated.
