Along with the recent advances in quantum computers, it is anticipated that cryptographic attacks using them will make it insecure to use existing public key algorithms such as RSA and ECC. Currently, a lot of researches are underway to replace them by devising PQC (Post Quantum Cryptography) schemes. In this paper, we propose a performance enhancement method for Lizard implementation which is one of NIST PQC standardization submission. The proposed method is able to improve the performance by 7 ~ 25% for its algorithms compared to the implementation in the submission through the techniques of various implementation aspects. This study hopes that Lizard will become more competitive as a candidate for PQC standardization.

Enterprise resource planning (ERP) is widely adopted among enterprises and organizations. In recent years, researchers have become increasingly interested in factors related to ERP implementation success. In this paper, top management members, IT professionals, and end-users were interviewed in the study. The study used Hofstede's main cultural dimensions as a theoretical framework to identify cultural characteristics and their influence on ERP implementation within public organizations in Saudi Arabia. The study followed a qualitative methodology approach to carry on the study to investigate the national culture characteristics in Saudi Arabia that may influence ERP implementation success. The study found some culturally related factors that could influence success in ERP implantation projects in Saudi Arabia..

This study aims to investigate the implementation of village fund (VF) policy in Indonesia by addressing the following issues: (1) what is the VF policy; (2) factors that support and hinder policy implementation; (3) impact of policy implementation; and (4) model for implementing village fund policies that can improve community welfare. Through a descriptive qualitative-based approach, several indicators are measured, namely, the substance of implementing rules, the results of project implementation, supporting and inhibiting factors for policies, participation factors, and the impact generated by village fund policies, which include social and economic effects. The extraction of this information and indicators will lead this study to produce ideal models and propositions for quantitative confirmatory research as a future research agenda. This study was conducted in two villages (Mojomulyo and Tambakromo) in Pati District, Central Java, Indonesia. Data collection model using interviews and observations from all actors who play a role (e.g., village government, village supervisory agency, and community). The study results show that policies have been implemented by normative rules; there are several supporting and inhibiting factors both internal and external. The study results also confirm the relevance of the articulated theory and some comprehensive input to our study.

The Dynamic Safety System (DSS) is a compute. based reactor protection system that has fail-safe nature and perform dynamic self-testing. In this paper, the implementation of DSS in PLC is presented for PWR. In order to choose adequate PLC implementation model of DSS, the reliability analysis is performed. The KO-RI unit 2 Nuclear power plant is selected as the reference plant, and the verification is carried out using the KO-RI unit 2 simulator FISA-2.

This paper reports on a contingency framework for selecting the most appropriate strategy to implement the enterprise Resource Planning(ERP) system in an organization. The two dimensions of our framework are information technology level and culture level of organization. For each of the four contingencies, we recommend a desirable implementation strategy, based on scope and pace of the implementation effort. ERP implementation data from ten organizations were analyzed to validate the proposed framework.

An implementation of 6 sigma in foodservice management was introduced from 2000. However they could not achieve full advantages of 6 sigma management because of short period of implementation time, and the critical problem is employees' complaints and their oppositions. The purpose of this study is to analyze the relationship of 6 sigma and organizational commitment in the foodservice industry. In this study, we found that organizational commitment improve with the implementation of 6 sigma. 6 sigma's essential factors have influenced on the organizational commitment.

This paper describes the design and implementation of the database which is used in Personal Life Log Media system. The database contains information about media that capture personal experiences and enables the user to retrieve the media in a user friendly ways. The implementation of the database design is done by managing video data, which captures user's personal experiences, with its spatial and temporal information. The database enables the user to retrieve the video by mentioning where and/or when the video has been taken.

It is essential to develop the internetworking strategies between the OBP satellite B-ISDN and the terrestrial B-ISDN for the economical and efficient implementation of the future network infrastructure. We have considered the implementation issues of the emerging B-ISDN, especially interworking strategies of the terrestrial B-ISDN with the OBP satellite B-ISBN. We proposed interworking model between terrestrial B-ISDN and OBP satellite B-ISDN NNI signaling protocol, and describes the design and verification of the interworking protocol. For the verification, interworking protocol is modeled by Predicate/Action Net derived from Petri Net and the designed model is analyzed by reachability tree. Using Unix socket, the verified interworking protocol is implemented in two workstations and implemented interworking protocol is tested by local test method which is outstanding in error detection and recommended by ISO.
