사물인터넷의 발달에 따라 IOT 장비의 보안 중요성도 더욱 가중되고 있다. 특히 사물인터넷의 특성 상 수십, 수백 개에 이르는 IP 카메라, 홈 IOT 장비, 다양한 측정 장비 등의 계정 관리는 시스템 관리자나 사용자들이 필수적으로 수행해야 하는 번거로운 작업이 되었다. 본 논문에서는 사물인터넷 상에 사용될 수 있는 다양한 장비들의 계정 관리를 체계적으로 설계하여 사용자에게 업무 효율을 높일 수 있는 시스템을 제안한다. 계정 관리의 주요 기능을 6 가지 기능으로 나누어 제공하고 기존의 시스템들보다 개선된 기술들을 적용하였다. 제안 시스템은 권위있는 기관의 인증 테스트를 성공적으로 통과하여 현재 실무 현장에 활용되고 있으며 향후 AI 기술을 적용한 스마트 계정 관리 시스템으로 개발 중이다.

As a corporate and a taxation account have relationships each other, one cannot be ignored by the other from concrete and excepted points of view. In reality, as they are mixed and the taxation account has been regarded as absolute, we cannot deny that the role of a pure corporate account is intruded by taxation account. Therefore, it is important that both should be adjusted in order to develop their own roles between a corporate account and a taxation account. In order to develop the both accounts soundly, we should solve the problems as follows. First, we should discriminate closing adjustment affairs from reporting adjustment ones, In the process of adjusting for taxation report. Second, the manager and the accounter need to comprehend on the origin and reality of a corporate and a taxation account and improve their capacity of accounting. Finally, as the goals which both aspects seek for are different, it is difficult to meet each other. But it will be a shortcut for enhancing the capacity of the corporate management, and developing the accounting systems of Korea, to compensate the differences each other. In conclusion, this writer suggest that the corporate accounts should be treated according to the corporate accounting principle, and taxation law has to be reformed so that taxable income may be counted based on the former assertion.

Studies in key account management (KAM) have identified the importance of cross-functional coordination in firms to effectively implement KAM. However, these studies have ignored how companies integrate KAM and other customer management (non-KAM). This paper explores coordination design between KAM units and non-KAM units by analyzing a case study through three dimensions: front-end coordination, back-end-coordination, and organizational translation at the beginning of research. The case study shows that non-KAM conditions can require a modification of the coordination design. This research performs an in-depth analysis of changes in the implementation of sales reforms for an IT-related machinery and system vendor in Japan. Data sources include interviews with KAM units and non-KAM sales units and an analysis of secondary data. This paper suggests that studying the coordination between KAM units and non-KAM units will further our understanding of internal coordination in KAM research.

In addition to enabling access, database accounts play a protective role by defending the database from external attacks. However, because only a single account is used in the database, the account becomes the subject of vulnerability attacks. This common practice is due to the lack of database support, large numbers of users, and row-based database permissions. Therefore if the logic of the application is wrong or vulnerable, there is a risk of exposing the entire database. In this paper, we propose a Least-Privilege Account Separation Model (LPASM) that serves as an information guardian to protect the database from attacks. We separate database accounts depending on the role of application services. This model can protect the database from malicious attacks and prevent damage caused by privilege escalation by an attacker. We classify the account control policies into four categories and propose detailed roles and operating plans for each account.

공용 블록체인 기반 가상 암호화폐의 이용이 증가함에 따라 암호화폐 지갑 프로그램을 통해 관리되는 블록체인 계정 정보의 안전한 관리가 요구되고 있다. 기존에 제안된 블록체인의 계정 관리를 위한 지갑 프로그램은 계정의 개인 키 관리 측면에서 높은 보안성을 가지지만 계정 복구 문자열 관리에 대해서는 낮은 보안성을 가지고 있다. 따라서, 본 논문에서는 사용자의 모바일 기기 정보와 OTP 기법을 이용한 새로운 사용자 인증법 기반의 블록체인 계정 복구 문자열의 안전한 관리 체계를 제안하여 기존 계정 복구 문자열 관리 방식의 문제점을 극복하고자 한다. 또한, 예상 행동 시나리오를 기반으로 제안된 블록체인 계정 복구 문자열 관리 체계에 대한 분석을 진행한다.

An integrated waste management approach for irradiated graphite was developed during the European Commission project 'Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste'. This included the identification of potential options for the management of irradiated graphite, taking account of storage, retrieval, treatment and disposal methods. This paper describes how these options can be assessed using multi-criteria decision analysis (MCDA) for a case study relating to a generic power reactor. Criteria have been defined to account for safety, environmental, economic and socio-political factors, including radiological impact, resource usage, economic costs and risks. The impact of each option against each criterion has been assessed using data from the project and the wider literature. A linear additive approach has been used to convert the calculated impacts to scores. To account for the relative importance of the criteria, example weightings were allocated. This application has shown that MCDA approaches can be used to support complex decisions regarding irradiated graphite management, accounting for a wide range of criteria. Use of this approach by individual countries or organisations will need to account for the specific options, scores, weightings and constraints that apply, based on their national strategies, regulatory requirements and public acceptability.

Since social network service (SNS) has been widely used as a effective way for people to connect and communication with each other, the use of corporate SNS account also has increased. However, compared to a private SNS account, only few people have a continuous relationship with their corporate SNS account because the use of corporate SNS account tends to be one-time and temporary activity whenever the users just need events and information. Given the psychological side effects of using SNS, the relative lack of empirical studies on the impacts of emotional factor in SNS prevents the deeper understanding of the intention to continuous using corporate SNS account. Therefore, this study aims to explore key determinants of the intension to continuous using the corporate SNS account from a habit and emotional perspective. To bridge research gap, we attempt to divide emotional factor into the following 5 factors based on Mehrabian and Russell model (1974): intimacy, enjoyment (positive factor), privacy concern, anxiety (negative factor), arousal (arousal factor) and (dominant factor). The basic model is proposed to explore the effects of habit and emotional factors on the intension to continuous using the corporate SNS account. We then examine how the effects of habit and emotional factors differ depending on social media types (e.g., facebook and twitter). The results indicates that habit is related to emotional factors, and each emotional factor differently influences the intension to continuous using the corporate SNS account. The results also confirm that the effects of the habit and emotional factors on the intension to continuous using the corporate SNS account differ according to social media types. This study provides practical and useful guidance and the strategic marketing insight for managers in maintaining and improving the intension to continuous using the corporate SNS account.

시스템 접근통제를 위한 솔루션은 사용자 개인을 시스템에 인증시키고자 할 때 사용된다. 이러한 유효한 사용자는 과연 바로 권한이 있는 사용자인가 하는 부분으로, 유효한 사용자의 적합성의 여부가 인증되었는지 확실하지 않다는 점이 문제이다. 예를 들어, 한 명의 개발자가 Unix 운영시스템에는 유효할 수 있지만, 권한이 없는 시스템에 대해서는 접근에 제한되어야 한다. 본 논문에서는 1개의 계정으로 여러 사용자가 사용하는 시스템운영의 문제점을 개선하기 위한 세밀한 권한 위임, 세션 감사, 관리자 계정의 정책기반 관리, 모든 권한을 갖는 관리자 계정 배급의 관리와 감사 기능을 통해 시스템 전체적인 접근 제어 방안을 연구한다.
