  • 그 동안 프라이버시 역설 현상을 설명하기 위한 많은 노력에도 불구하고 기존 연구들은 상반된 결과들을 보고하였다. 일부 연구들은 프라이버시 염려와 자기노출 사이의 관련성을 발견한 반면, 다른 연구들은 그렇지 못했다. 본 연구는 SNS 환경에서 이러한 관련성에 영향을 미칠 잠재력이 있는 상황변수로 상호작용 프라이버시 컨트롤(주로 프렌드 리스트와 프라이버시 셋팅)의 역할을 검토한다. 이러한 이유는 사용자들이 상호작용 프라이버시 컨트롤을 사용하여 자신의 사회적 환경을 조성하기 때문에 이것의 사용정도에 따라 프라이버시 염려와 자기노출 사이의 관계가 영향을 받기 때문이다. 본 연구는 서베이 방법을 활용하였고, 위계적 다중회귀분석을 사용하여 상호작용 프라이버시 컨트롤 사용의 조절효과를 분석하였으며, 분석결과 상호작용 프라이버시 컨트롤 사용의 조절효과를 발견하였다. 따라서 상호작용 프라이버시 컨트롤의 사용은 SNS를 대상으로 프라이버시 역설 현상을 검토하는 연구에서 고려해야 하는 중요한 상황변수라고 할 수 있다.

  • 소셜미디어는 쾌락적인 속성을 갖는 정보시스템이기 때문에 소셜미디어 연구에서는 즐거움이 핵심 변수이어야 한다. 그러나 이러한 당위성에도 불구하고 소셜미디어 환경에서 즐거움에 대한 연구는 아직 초기 단계에 머물러 있고, 특히 즐거움의 선행변수에 관한 연구는 거의 이루어지지 않고 있다. 본 연구의 목적은 즐거움의 선행변수로서 상호작용 컨트롤과 즐거움 사이의 관련성을 검토하는 것이다. 이를 위해 본 연구는 자기결정이론에 근거하여 이 두 변수들 사이의 관련성에 관한 이론적 메커니즘을 수립하고 실증한다. 본 연구는 데이터 수집을 위해 서베이를 실시하였다. 연구 결과, 본 연구는 상호작용 컨트롤 사용이 관계 욕구 만족과 자율 욕구 만족에 대한 1차적 영향을 거쳐 즐거움에 영향을 미친다는 사실을 발견하였다. 본 연구는 이러한 연구 결과를 토대로 이론적, 실무적 시사점을 논의하고 연구 한계를 설명한다.

  • Recently there has been a marked increase in concern for security in computerized operations. The purposes of computer security controls are to protect against the unauthorized access to and modification of data processing resources, unauthorised access to and modification of data files and software, and the misuse of authorized activities. The controls relate to the physical security of the data processing department and of the areas within the data processing department : to the security of the data files, programs, and system software : and to the human interaction with the data files, programs, and system software. The controls that will be discussed in this paper include : I. Risk on the computer use. II. Methods of risk counter measure. III. Role of system auditing.

  • SNS 환경에서 자기노출로 인한 프라이버시 침해의 위험성이 증가함에 따라 많은 연구들이 자기노출에 영향을 미치는 요인들을 발견하고자 노력해 왔다. 본 연구는 이러한 연구흐름의 연장선상에 있으며 새로운 영향요인으로 상호작용 프라이버시 컨트롤(프렌드 리스트와 프라이버시 셋팅들)의 역할에 관심을 갖는다. 구체적으로 본 연구는 상호작용 프라이버시 컨트롤을 활용하여 개인들 사이의 상호작용을 효과적으로 통제하는 능력(상호작용 프라이버시 컨트롤의 유용성)이 자기결정이론에서 제안하는 3가지 심리적 욕구들(자율욕구, 관계욕구, 역량욕구)을 만족시키고 이어서 자기노출을 증가시킬 것이라는 논리를 이론화하고 실증한다. 데이터 분석결과, 상호작용 프라이버시 컨트롤의 유용성은 심리적 욕구 만족들에 매우 강한 영향을 미치고 사용자들이 자기노출의 정도를 높이는 주요한 원인인 것으로 밝혀졌다. 본 연구는 이러한 연구결과를 토대로 이론적, 실무적 시사점 및 향후 연구 방향에 관해 논의한다.

  • The differential settlements and rotations among footings cannot be avoided when the frame-footing-soil system is subjected to seismic/dynamic loading. Also, there may be a situation where column(s) of a building are located near adjoining property line causes eccentric loading on foundation system. The strap beams may be provided to control the rotation of the footings within permissible limits caused due to such eccentric loading. In the present work, the seismic interaction analysis of a three-bay three-storey, space frame-footing-strap beam-soil system is carried out to investigate the interaction behavior using finite element software (ANSYS). The RCC structure and their foundation are assumed to behave in linear manner while the supporting soil mass is treated as nonlinear elastic material. The seismic interaction analyses of space frame-isolated footing-soil and space frame-strap footing-soil systems are carried out to evaluate the forces in the columns. The results indicate that the bending moments of very high magnitude are induced at column bases resting on eccentric footing of frame-isolated footing-soil interaction system. However, use of strap beams controls these moments quite effectively. The soil-structure interaction effect causes significant redistribution of column forces compared to non-interaction analysis. The axial forces in the columns are distributed more uniformly when the interaction effects are considered in the analysis.

  • This study presents a methodology for simulating a unified approach that controls interaction force between tool and objective by using a synthesis method of robot interacting control law for stabilizing the transient process of motion. Root locus is used to analyze stabilization of motion deviation characteristics. Based on responses of motion deviation, contact force is derived to satisfy exponential stability and we generate control input with respect to motion trajectories and interaction force. Moreover, simulation is applied to experimental application of a Cartesian robot driven by two stepper motors, and the noise of feedback signals is considered as presence of system inaccuracies, and the unified approach of interaction force control is examined precisely.

  • Traditional tactile controls that include push buttons and rotary switches may cause significant visual and biomechanical distractions if they are located away from the driver's line of sight and hand position, for example, on the central console. Gestural controls, as an alternative to traditional controls, are natural and can reduce visual distractions; however, their types and numbers are limited and have no feedback. To overcome the problems, a driver interface combining gestures and visual feedback with a head-up display has been proposed recently. In this paper, we investigated the effect of this type of interface in terms of driving performance measures. Human-in-the-loop experiments were conducted using a driving simulator with the traditional tactile and the new gesture-based interfaces. The experimental results showed that the new interface caused less visual distractions, better gap control between ego and target vehicles, and better recognition of road conditions comparing to the traditional one.

  • This paper proposes a robot motion authoring using finger-robot interaction. The proposed method is a user friendly method that easily authors (creates and controls) robot motion according to the number of fingers. The effectiveness of the proposed motion authoring method was verified based on motion authoring simulation of an industrial robot.

  • Use cases are commonly used to represent customer requirements during systems development. In a large software development environment, finding relevant use cases from a library of past or related projects is a complex, error-prone and expensive task. This study proposes an ontological methodology to support use case retrieval in an interactive manner. The architecture of a prototype system that implements this methodology is presented. To evaluate whether the proposed approach can provide satisfactory results to users, this study develops a research model and hypotheses based on interaction theory. These hypotheses are empirically tested using a laboratory experiment which controls information filtering and perceived interaction. Our study suggests that a system which interacts with a user intelligently reduces cognitive load and increases self-efficacy and satisfaction.

  • Research in Human Computer Interface (HCI) is towards development of an application environment able to deal with interactions of both human and computers that can be more intuitive and efficient. This can be achieved by bridging the gap between the synthetic virtual environment and the natural physical environment. Thus a project called Tangible Space Initiative (TSI) has been launched by KIST. TSI is subdivided into Tangible Interface (TI) which controls 3D cyber space with user's perspective, Responsive Cyber Space (RCS) which creates and controls the virtual environment and Tangible Agent (TA) which senses and acts upon the physical interface environment on behalf of any components of TSI or the user. This paper is a brief introduction to a new generation of Human Computer Interface that bring user to a new era of interaction with computers in the future.
