Investment authorities are broad financial institutions that carefully manage investments on behalf of the national government using a long-term value development approach. To provide a stronger structure or framework for In-vestment Authorities to govern the distribution of funds to public and private markets, we've started research to create a blockchain-based prototype for managing and tracking numerous finances of such authorities. We have taken the case study of Oman Investment Authority (OIA) of Sultanate of Oman. Oman's wealth is held in OIA. It is an organization that oversees and utilizes the additional capital generated by oil and gas profits in public and private markets. Unlike other Omani funds, this one focus primarily on assets outside the Sultanate. The operation of the OIA entails a huge number of transactions, necessitating a high level of transparency and administration among the parties involved. Currently, OIA relies on various manuals to achieve its goals, such as the Authorities and Responsibilities manual, the In-vestment Manual, and the Code of Business Conduct, among others. In this paper, we propose a Blockchain based framework to manage the operations of OIA. Blockchain is a part of the Fourth Industrial Revolution, and it is re-shaping every industry. The main components of every blockchain are assets and participants. The funds are the major assets in the proposed study, and the participants are the various fund shareholders/recipients. The block-chain's transactions are all safe, secure, and immutable, and it's part of a trustless network. The transactions are simple to follow and verify. By replacing intermediary firms with smart contracts, blockchain-based solutions eliminate any middlemen in the fund allocation process.

정보보호는 외부 사이버공격으로부터의 보호와 더불어 내부자료 유출 위험요인을 사전에 식별하여 차단하는 것이 중요하다. 이를 위해 많은 기업과 기관에서는 자료(파일) 자체를 암호화해 외부로 유출 시 내용확인을 불가능하게 DRM(Digital Rights Management) 문서보안 솔루션과 전산장비의 USB포트 등 매체제어를 통해 데이터 유출방지를 위한 DLP(Data Loss Prevention) 솔루션을 대표적으로 운용하고 있다. 이와 같이 내부 자료유출 방지 노력이 중요한 시점에서 관리 사각지대에 놓일 수 있는 단독망 환경의 정보자산 식별과 매체제어와 같은 통제정책 운용이 요구된다. 본 연구에서는 내부 업무망에도 연결되지 않는 단독망 정보자산의 인증을 통해 해당 정보자산에 유일하게 적용되는 매체통제정책 생성-배포-적용 모델을 제시하였으며, 이를 위해 정보자산 획득 시 자동으로 등록되는 자산관리시스템 정보와 연계한 인증기법을 개발하여 정확한 정보자산 식별 및 유연한 매체통제가 가능한 시스템을 설계 및 구축하였다.

Big Data is a data analysis technology empowered by late advances in innovations and engineering. In any case, big data involves a colossal responsibility of equipment and handling assets, making reception expenses of big data innovation restrictive to little and medium estimated organizations. Cloud computing offers the guarantee of big data execution to little and medium measured organizations. Big Data preparing is performed through a programming worldview known as MapReduce. Normally, execution of the MapReduce worldview requires organized joined stockpiling and equal preparing. The computing needs of MapReduce writing computer programs are frequently past what little and medium measured business can submit. Cloud computing is on-request network admittance to computing assets, given by an external element. Normal arrangement models for cloud computing incorporate platform as a service (PaaS), software as a service (SaaS), framework as a service (IaaS), and equipment as a service (HaaS).

ISP 네트워크의 보안수준 진단과 대응방안을 수립하기 위해서는 네트워크상의 정보자산에 대한 취약점과 위협 요인을 식별하고, 피해 발생시 예상되는 손실의 정도를 산정하는 위험분석 절차가 필수적이다. 하지만, 기존의 위험분석 방법론 및 도구들은 대부분 방법론적 분석절차와 수단만을 제공하며, 개별 시스템의 취약점 및 위협요인의 변동정보를 실시간으로 반영할 수가 없다. 따라서. 본 논문에서는 네트워크 침입탐지 시스템과 취약점 분석 시스템의 탐지 정보들을 실시간으로 수집, 분석하여 네트워크 자산에 발생할 수 있는 위험의 가능성을 찾아내고, 정량적인 위험수준을 평가하는 시스템을 제안한다. 또한, 실험을 통해 시스템의 성능수준을 제시하였다.

Paying close attention to those new to an organization, whether fresh or experienced, whose primary interest is in (re)socialization, the current study intends to (1) further the concept of mentoring from a bilateral relationship to a community and culture fostered by developmental networks, (2) propose an integrated conceptual framework for organizational socialization, and (3) suggest implications for practice and future research. This study reviews, analyzes, and integrates research assets and subsequently re-conceptualizes the aggregate information as valid propositions and a conceptual framework. The findings include (1) 11 propositions regarding the relationships among network characteristics (embeddedness, diversity), developmental functions (career support, psychosocial support, and role modeling), and socialization outcomes (learning and attitudinal outcomes); and (2) an integrated conceptual framework that depicts a comprehensive mechanism through which developmental networks conduce to organizational socialization of newcomers. Implications are that developmental networking must be an individual's fundamental competency and an essential part of organizational onboarding processes, and imperative for both members' career development and innovative organizational culture. By integrating research assets on the developmental phenomenon into conceptualizations, this study furthers the concept of mentoring to organizational culture and stimulates a substantive discourse for theory-building towards organizational socialization from the developmental network perspective.

The use of the internet to facilitate commerce among companies promises vast benefits. Lots of e-marketplaces are building for several industries such as chemistry, airplane, and automobile industries. This study proposed new B2B EC business model for the shipping industry which concerns relatively massive fixed assets to be fully utilized. To be successful the proposed model gives participants to support useful information. To do this the expert system is constructed as the hybrid prediction system of neural network (NN) and memory based reasoning (MBR) with self-organizing map (SOM) and knowledge augmentaton technique using qualitative reasoning (QR). The expert system supports participants useful information coping with dynamic market environment. with this transportation companies are induced to participate in the proposed e-marketplace and helped for exchanges easily. Also participants would utilize their assets fully through B2B exchanges.

It is a common practice to use a password in order to restrict access to information, or in a general sense, to assets. Right selection of the password is necessary for protecting the assets more effectively. Password finding/cracking try outs are performed for deciding which level of protection do used or prospective passwords offer, and password cracking algorithms are generated. These algorithms are becoming more intelligent and succeed in finding more number of passwords in less tries and in a shorter duration. In this study, the performances of possible password finding algorithms are measured, and a hybrid algorithm based on the performances of different password cracking algorithms is generated, and it is demonstrated that the performance of the hybrid algorithm is superior to the base algorithms.

Blockchain is a decentralized network in which data blocks are linked. Through a decentralized peer-to-peer network, users can create shared databases, resulting in a trustworthy and aggregated database known as a blockchain that enhances reliability and security. The distributed nature of the blockchain enables data to be stored on multiple nodes, eliminating the need for a central server or platform. This disintermediation significantly reduces the transaction and administrative costs. The blockchain is particularly valuable in applications where reliability and stability are critical because it establishes an open database that ensures data integrity, making it virtually impossible to tamper with or falsify data. This study explores the diverse applications of the blockchain technology in virtual assets, such as cryptocurrency, decentralized finance, central bank digital currency, nonfungible tokens, and metaverses. In addition, it analyzes the potential prospects and developments driven by these innovative technologies.
