Home network is the connection and communication of several electronic and electrical devices at hone with the integration of several technologies like Ethernet, wireless, phone line and power-line at the residential gateway to the internet. This internet based home network can be accessed from any part of the world through any device by any poison via internet. Since home network is developed for comfortable and safe life of home users, the information flow to/from home network needs to be private. Hence the remote access of the home network must be secured. This paper analyses two secure tunneling methods, voluntary and compulsory for L2TP(Layer Two Tunneling Protocol) based VPN(Virtual Private Network) for secure remote access of the home network.

최근 20년간 마케팅을 비롯하여 사회과학 전반에 걸쳐 기업이론에 관하여 새로운 패러다임으로 각광을 받아온 신제도학파 접근방법은 이익극대화를 기업의 중심적 행동으로 가정하고 있는 신고전학파의 맹점을 극복하여 조직문제를 포괄적으로 다룰 수 있음을 보여주고 있다. 이 이론은 한정된 합리성, 기회주의, 자산 특수성, 지배구조, 신뢰 및 협동 등의 핵심적 개념들이 동태적 환경 하에서 활동하고 있는 기업의 경제적 행동을 분석하고 이해하는데 크게 기여하였음이 입증되고 있다. 이것은 다수의 실증적 문헌들에서 엿볼 수 있다. 그러나 신제도학파의 이론적 틀은 두 가지 면에서 주요 결점을 안고 있다. 그 하나는 이론의 정당성을 입증하기 위한 실증적 연구결과물을 무수하게 찾아볼 수 있으나, 대부분이 연구의 타당성이 결여되어 있다는 점이고, 또 하나의 결정적 결함은 신고전학파와 마찬가지로 비교정태적 접근방법을 택함으로써 역사적 관점이 도외시되고 기업의 전략개발과 구조적 변동을 이해하는데 필수적인 조직과 기술간의 동태적 상호작용의 중요성을 간과하고 있다는 점이다. 이에 따라 본고에서는 국제교역 이론가들이 제시한 기업 특유의 경쟁우위에 관한 착상과 그러한 우위가 기업 내외의 네트워크 형성을 포함하여 결집된 조직역량에서 도출된다는 견해를 거래비용이론에 접목시킴으로써 기업의 성격과 그 성장방식을 보다 설득력있게 이해할 수 있으리라는 관점을 제시하려 하였다. 이와 같이 거래비용이론과 진화론을 결합하면 신제도학파 기업이론의 결점이 보완되고 이론의 발전이 한 단계 진일보할 것으로 기대된다. 특히 마케팅 연구자들이 거래비용이론의 경우와 마찬가지로 본고에서 제시한 통합이론에 대해서도 실증적 연구를 행하면 이론개발에 크게 기여할 것으로 생각된다.

Urban space structure tends to have a significant change in accordance with maintenance of urban infrastructure such as a traffic route. For this reason, quantitative analysis has been needed to establish spatial distribution and location patterns by considering change of both road accessibility and urban infrastructure level, which can have the most pervasive influence in urban development process. Therefore, this paper aims to analyze spatio-temporal urban morphology through considering distribution patterns of road among transportation infrastructures, population, and spatial structure of metropolitan areas, focusing on Seoul where population growth and the size of urban area have been dramatically increased. For this, we firstly developed and constructed time-series GIS database by using satellite images and topographic maps of the last 70 years to analyze variables which affect urban growth and transportation. In particular, we analyzed the transform of the system of the street by Space Syntax which is able to grasp hierarchical spatial structure through visibility of space and spatial cognition in terms of accessibility. What's more, we analyzed and visualized the relationship urban morphology and road according the regions of Seoul through IPA(Importance Performance Analysis). In terms of the integration land-use and transportation, Space Syntax approach is expected to contribute to efficient urban planning through understanding the influence which various transportation phenomena has an effect on urban development patterns.

Service quality research is being conducted actively to improve customer satisfaction in various fields, but no research has been done on the service quality of small arms in the national defense. To enhance the user satisfaction and quality of small arms, this study aimed to derive the main quality attributes, measure the current level of satisfaction, and explore the elements requiring improvement. For this, a questionnaire survey based on the Kano model and SERVQUAL model was conducted on the identified service quality factors through discussions of experts involved in the production, quality assurance, and operation. All service quality factors were classified as one-dimensional elements, and an analysis of the Kano-SERVQUAL integrated approach showed that the user's expectation and dissatisfaction coefficient had a strong positive correlation with a 1% significance level, and user's perception value and satisfaction coefficient had a negative correlation with the 1% significance level. Using the Kano-SERVQUAL integrated approach, the priority service quality attributes for small arms requiring improvement among the many areas of service quality could be identified. Overall, it is expected that service-quality-level measurements can be used to improve the quality level of munitions as well as user satisfaction.

This study explored pre-service teachers' mental models about eclipse phenomena to investigate their understandings on the earth science concept needed f3r an integrated approach. We conducted in-depth interviews with two different contexts on 30 secondary and 36 primary pre-service teachers participants, and analyzed phenomenological primitives (p-prims) and facets of causal explanations about eclipses. Based on this study, we identified four different levels of mental models about eclipses. Four mental models were categorized as (1) Screening model, (2) Orbital plane model, (3) Hybrid model, and (4) Shadow cast model. Screening model is a flawed mental model, orbital plane model is an incomplete correct mental model, and shadow cast model is a scientifically correct mental model. Hybrid model, composite of two or more mental models, use multiple mental models simultaneously. Orbital plane model was the most widespread mental model in secondary pre-service teachers group, whereas screening model was used frequently in primary group. It was found that the level of mental model could be determined by the level of facet and p-prims. We confirmed context sensitivity of the mental models and perceived the necessity of integrated approaches to promote progression of mental models. Implications of our findings for enhancing pre-service science teachers' topic-specific pedagogical content knowledge (PCK) associated with eclipse phenomena are also discussed here.

Anger cause heart disease and domestic violence and recently there have been an increasing number of media reports of crimes committed because of their inability to control their anger. Anger has been reported to cause massive financial losses due to heart disease and domestic violence. Therefore, since anger raises serious social problems and social costs, it is necessary to take active intervention methods to alleviate inappropriate anger coping. A variety of methods such as cognitive and emotional approach, psycho-mechanical approach, psycho-educational approach, relaxation therapy, cognitive behavior-art therapy, and stress immunization are being explored and utilized for presenting effective anger-coping intervention alternatives. In this manner, information and communication technology is likely to be used as an effective means for this, and various researches are being conducted. The purpose of this study is to develop an anger coping service technology using ICT (Information & Communication Technology) technology as an effort to improve anger coping ability. In other words, the goal is to develop a technology that delays anger and evokes the surroundings by providing location-based services to recognize anger situations and facilitate anger. This research is about the technology which intervene directly the anger situation to resolve it using location information and introduce the base technology to realize it.

A home network is a residential local area network in which digital home appliances are connected with each other. Applying the mobile agent technology to the home network is expected to provide a new computing model. In particular, mobility and asynchronous ability of mobile agent can be used to reduce network traffic generated for managing home appliances. However, in order to apply the mobile agent concept to the home network, access control for mobile agents is necessary. In the existing home network system, there is one special server, sometimes called home server This server generally has mapping tables to be updated periodically, which describes access control lists between users' authorities and corresponding devices. In this paper, we propose a role-based access control framework with mobile agents in home networks. This framework, called Secure KAgent framework, is designed and implemented based on KAgent system. It has two main characteristics: to control access permissions based on Role-Based Access Control(RBAC) scheme and to safety assign roles to mobile agents by role tickets.

The physical access or control of records with material entities is relatively easy. However, in the case of electronic records, due to its heightened applicative aspect that allows anyone with the authority to have access over the data, it requires an appropriate standard and stability to ensure the authenticity and integrity of electronic records. This study performed functional evaluation by extracting the minimum critical items from the national functional requirements documents and standards to explore the access control function that play an important role for the standard records management system to maintain quality requirements of electronic records. Based on this checklist, it evaluates whether the standard records management system properly carries out the access control function and investigates the current condition of application to practical records management work. Records managers generally do not use access control function, which may be because they do not feel the necessity, since the application of records management system is not yet actively promoted. In order for the standard records management system to be developed to become a more active system, it requires system improvement as well as considerations for below factors: First, although the necessity of establishing access control conditions is already recognized, it requires a clear stipulation of the regulation. Second, measures must be taken to implement access control in the records management system through document security solution. Third, it requires self-reflection of records manager, who utilizes the records management system. Instead of placing all responsibility on the National Archives, which established the system, professionals must further develop the system through continuous evaluation and improvement. Finally, a general discussion is required to publicize the issue of functional improvement of records management system. Although there is a bulletin board already created for this purpose, its users are extremely limited and it only deals with current problems. A space in online as well as in offline is required to solve the fundamental problems and exchange opinions.
