This paper seeks to measure the monetary value of technical development in the deep seabed manganese nodule mining by applying the compound option model (COM). The COM is appropriate for the project in terms of its decision-making structure and embedded uncertainty. The estimation results show that the deep seabed mining project has more economic potential than shown by the previously obtained results from the discounted cash flow (DCF) analysis. In addition, it is reasonable to invest in the project taking the various uncertainty factors into consideration, because the ratio of the value to the cost of the project is far higher than one. This information can be utilized in national ocean policy decision-making.

Purpose Issues related to information security have been a crucial topic of interest to researchers and practitioners in the IT/IS field. This study develops a research model based on a Structure-Conduct-Outcome (SCO) framework for the social exchange relationship between employees and organizations regarding information security. Design/methodology/approach In applying an SCO framework to information security, structure and conduct are activities imposed on employees within an organizational context; outcomes are activities that protect information security from an employee. Data were collected from 438 employees working in manufacturing and service firms currently implementing an information security policy in South Korea. Structural equation modeling (SEM) with AMOS 22.0 is used to test the validation of the measurement model and the proposed casual relationships in the research model. Findings The results demonstrate support for the relationships between predicting variables in organization structure (security policy and physical security system) and the outcome variables in organization conduct (top management support, security education program, and security visibility). Results confirm that the three variables in organization conduct had a positive effect on individual outcome (security knowledge and compliance intention).

Our study adopted ELM (Elaboration Likelihood Model) to measure the impact of central and peripheral cues on e-healthcare website behavior and its consequence on perceived loyalty of users. While most of ELM studies did not elaborate the antecedent of both central and peripheral cues, we measured the antecedents of those information processing routes to clarify how technical and quality factors (i.e. information organization, security concern, and website attractiveness) develop the nature of either central or peripheral route. We found that information organization was the main antecedent of information quality presented on the website. Second, the results revealed that website security has a positive effect on website credibility. Third, we also found that website attractiveness was positively associated with website credibility. Fourth, consistent with elaboration likelihood model, the empirical findings suggested that information quality (central cue) and website credibility (peripheral cue) were strong predictors of behavior intention to use health website. Our findings also suggested that behavior intention to use health website significantly influenced perceived loyalty.

개인정보보호법 제정 이후, 개인정보보호를 위한 정책 및 관련된 제반활동이 활발하게 진행되고 있다. 하지만, 개인 정보 유출 사고가 계속 발생하면서 국민들은 개인정보보호에 대한 부정적인 태도를 보이고 있다. 이에 본 논문은 국가 개인정보보호 정책이 국민에게 어떠한 의미로 인식되는지 확인하고자, SERVQUAL 기법을 이용하여 국민의 인식 측면에서 정책의 효과성에 대한 실증적인 분석을 시도하였다. 분석 결과, 국민들은 국가 개인정보보호 정책이 효과적이라고 인식하지만 인식 수준 자체는 낮으며, 신속성, 편의성, 책임성에 대한 정책 효과를 높게 인식하지만 효율성에 대한 효과는 낮게 인식하고 있다. 국민이 만족하는 국민 지향적 개인정보보호 정책으로의 발전을 위해서는 국민의 기대/지각 인식과 효과성 인식 수준이 낮은 사항에 초점을 둔 정책의 개선이 요구된다.

역할기반 접근제어의 중요한 특징은 그 자체가 정책 중립적이라는 데 있다. 이것은 역할기반 접근제어에는 특정한 접근제어 정책이 내포되어 있다기 보다 응용 환경에 따라 요구되는 정책을 쉽게 표현할 수 있다는 것을 의미한다. 이런 이유로 전통적인 접근제어 정책인 강제적 접근제어 정책과 임의적 접근제어 정책을 역할기반 접근제어 모델로 구성 가능함을 보이고자 하는 연구가 진행되어 왔다. 특히, 역할기반 접근제어를 이용하여 강제적 접근제어를 표현하는 연구에서는 낮은 보안등급에서 높은 보안등급으로의 단방향 정보흐름을 유지할 수 있는 두 가지 규칙인 하향 갱신금지 규칙과 상향 판독 금지 규칙을 준수할 수 있도록 역할기반 접근제어의 일부 컴포넌트(사용자, 역할, 역할 계층, 세션)들을 재구성하고 제약사항들을 추가함으로써 해결하는데 초점을 두고 있다. 그러나 이런 기존 연구들은 비밀성 보장에 초점을 두었지만 실제 일부분에서 비밀성이 보장되지 못하고 있음을 밝힌다. 추가로 권한이 없는 사용자에 의한 정보 수정을 막는 무결성이 위반되고 있음을 밝힌다. 본 논문은 강제적 접근제어 정책에서 요구하고 있는 비밀성과 무결성을 동시에 만족시키는 역할기반 접근제어 모델을 제안한다. 역할기반 접근제어의 일부 컴포넌트들을 재구성하고 추가적인 제약사항들을 제안하였다.

When evaluating the economic value of technology or business project, we need to consider the period and cost for commercialization. Since the discounted cash flow (DCF) method has limitations in that it can not consider consecutive investment or does not reflect the probabilistic property of commercialization cost, we often take it desirable to apply the concept of real options with key metrics of underlying asset value, commercialization cost, and volatility, while regarding the value of technology and investment as the opportunity value. We at this moment provide more elaborated real options model with the effective region of volatility, which reflects the uncertainty in the option pricing model (OPM).

In this paper, we propose an efficient repository model for online software education. The software education of app development consists of 7 stages: coding & debugging, submit, collaboration, review, validate, deployment, certification. Proposed repository model supports all 7 stages efficiently. In the coding & debugging stage, the students repeat coding and debugging of source. In the submit stage, the output of previous process such as source codes, project, and videos, are uploaded to repository server. In the collaboration stage, other students or experts can optimize or upgrade version of source code, project, and videos stored in the repository. In the review stage, mentors can review and send feedbacks to students. In the validate stage, the specialists validate the source code, project, and the videos. In the deployment stage, the verified source code, project, and videos are deployed. In the certification stage, the source code, project, and the videos are evaluated to issue the certificate.

The problem surrounding methods of implementing the software testing process has come under the spotlight in recent times. However, as compliance with the software testing process does not necessarily bring with it immediate economic benefits, IT companies need to pursue more aggressive efforts to improve the process, and the software industry needs to makes every effort to improve the software testing process by evaluating the Test Maturity Model integration (TMMi). Furthermore, as the software test process is only at the initial level, high-quality software cannot be guaranteed. This paper applies TMMi model to Automobile control software testing process, including test policy and strategy, test planning, test monitoring and control, test design and execution, and test environment goal. The results suggest improvement of the automobile control software testing process based on Test maturity model. As a result, this study suggest IT organization's test process improve method.

네트워크를 기반으로 하는 시스템들의 발전으로 인하여 매우 다양한 침입이 확산되고 있다. 이러한 침입을 탐지 및 대응하기 위하여 방화벽 또는 IDS와 같은 보안 솔루션들이 생겨나고 있으며 이들을 탑재한 보안시스템의 관리가 더욱 힘들어지고 있다. 더욱이 보안을 요구하는 시스템들의 환경이 다양하여 그에 적합한 보안정책을 수립하여 관리하기가 어려워지고 있다. 따라서 다양한 보안시스템의 통합관리와 각 시스템들의 침입탐지 및 대응에 대한 모델이 필요하게 되었다. 본 논문에서는 광범위한 네트워크 자원을 관리하는 PBNM구조를 개선하고 보안시스템의 침입탐지 및 대응에 적합한 새로운 모델을 제시하였다. 또한 제시된 모델을 통합보안관리시스템에 적용시킴으로써 효과적인 침입탐지 및 대응을 위한 보안 정책 모델을 기반으로 통합보안관리시스템을 설계하였다.

Government-sponsored Research Institutes(GRIs) have made a great contribution to the development of Korea's Science and Technology(S&T). However, recently GRIs are facing the challenge of many problems. For instance, absence of reasonable strategies, insufficient resources and so on. Therefore, many GRIs are being asked for solving their problems with successful strategic management. This paper suggests a strategic management model to solve their problems and to cope with the changing S&T environment. In this paper, The strategic management model for GRIs which was thoroughly considered strategic management process suggested to response the need of their change and to perform their strategic management successfully. As a case of GRIs to apply this model, in this paper, Korea Basic Science Institute(KBSI) that is part of the Korea Research Council of Fundamental Science and Technology(KRCF) was analyzed. As a result of analysis with this model which applied to KBSI, various strategies and alternatives were suggested.
