본 연구는 도박중독자들의 회복과정에 대한 실체이론을 개발하기 위하여 실시하였다. '도박중독자의 회복과정은 어떠한가?'의 연구문제를 가지고, Strauss와 Corbin(1990)의 근거이론방법을 적용하여 분석하였다. 전라북도지역에 거주하는 남성 도박중독자 7명을 대상으로 심층 인터뷰하였다. 연구결과 총 97개의 개념과 28개의 하위범주 그리고 16개의 상위범주로 유목화 하였다. 회복과정의 핵심범주는 '대박의 꿈을 포기하고 자유로워지기'로 나타났다. 본 연구는 국내에서 처음으로 도박중독의 수렁에서 빠져나오는 과정과 유형 등을 밝힘으로써 도박중독자의 회복과정에 대한 실제적 이론 구축 및 정책적, 임상적 개입에 중요한 기초자료가 될 것으로 본다.

In this paper, a new driving mechanism of security robotswhich should overcome obstacles with stability even though movingin high speed is introduced. The driving mechanism has spring-based suspension and two wheels positively necessary to overcome obstacles. From the driving mechanism, it is mainly discussed how we can decrease overshoot and impulse occurred when the robot is in the process of overcoming obstacles. Finally, design parameters of the driving mechanism which guarantees stable motion while overcoming obstacles is deduced based on simulation results. Experiments are also followed to demonstrate how well the manufactured system works in its early stage of the practical use.

This paper introduces a novel obstacle-climbing robot that moves on the facade of buildings and its climbing mechanism. A winch system set on the top of the building makes the vertical motion of the robot while it climbs obstacles that protrude from the wall surface. The obstacle-climbing robot suggested in this research is composed of a main platform and three modular climbing units. Various sensors installed on each climbing unit detect the obstacles, and the robot controller coordinates the three units and the winch to climb the obstacles using the obstacle-climbing mechanism. To evaluate the performance of the developed robot prototype, a test bed, which consists of an artificial wall and an obstacle, was manufactured. The obstacle size and the time required to climb the obstacle were selected as the performance indices, and extensive experiments were carried out. As a result, it was confirmed that the obstacle-climbing robot can climb various-sized obstacles with a reasonable speed while it moves on the wall surface.

We define mathematical learning as a process of overcoming framing difference of teachers and students, two main subjects in a mathematics class. We have reached this definition to the effect that we can grasp a mathematical classroom per so and understand students' mathematical learning in the context. We could clearly understand the process in which the framing differences are overcome by analyzing mutual negotiation of informants in specific cultural models, both in its form as well as in its meaning. We review both of the direct and indirect forms of negotiation while keeping track of 'evolution of subject' in terms of content of negotiation. More specifically, we discuss direct negotiation briefly and review indirect negotiation from three distinct themes of (1) argument structure, (2) revoicing, and (3) development patterns and narrative structure of proof. In addition, we describe the content of negotiation under the title of 'Evolution of Subject.' We found that major modes of mutual negotiation are inter-reference and appropriation while the product of continued negotiation is inter-resemblance.

Various trials to overcome the limitation of current accounting which fails in synchronizing business activities and their information have failed to make satisfactory result merely showing a little saving of processing time. This is because such trials have been done within the boundary of double-entry bookkeeping system. Without consolidating business activities and their information, reformation efforts such as BPR(business process re-engineering), ABC(activity-based costing), CALS(commerce at light speed) etc to fit the business organization to the changing business environment could not be achieved. Overcoming the limitation of accounting takes precedence of any other attempt to construct the management information systems. Activity Information Accounting System(AIAS) proposes the way of overcoming the limitation of current accounting by using the new accounting methodology and unique solution to real time accounting information. AIAS produces accounting and management information directly of activity information without bookkeeping process of activity information. AIAS adopts method of transforming the details of corporation activities directly into accounting information rather than method of double-entry bookkeeping system. The purpose of this paper is to prove AIAS to be very flexible system by using flexibility concepts. Flexibilities are defined as three aspects, namely ① timeliness (rapid accounting information generations and presentations) ② easy systems modificabilities according to environment changes ③ adaptabilities to all industries.

The PID controllers which is widely used in the process industry are poorly damped when the dynamic process contains significant dead time or when there are random disturbances acting on the plant. GPC is known to be more superior than conventional self-tuning algorithm in overcoming above problem and prior choice of model order. In this paper, we propose the method which determine the parameter of PID controller from minimization of GPC criterion. The controller has emplicit scheme which is comprised of parameter estimation and PID control design. Simulation results show the performance of the proposed self-tuning PID controller.

Various organizational factors effect successful implementation of IT enabled business transformation. Among them, the most critical success factor is deemed to overcoming change management problem. Lots of studies have been made on Implementation methodologies and business process formalizations to encourage organizational members to accept new business process changes. However, the logic or process redesign still depends on qualitative problem solving techniques mostly depending on basically human intuition such as brainstorming. cause-and-effect analysis. and so on. In this paper, we focused on developing analytic framework to design to-be business process structure. which can complement qualitative problem solving procedures. With effective use of IT as an enabler, we provide algorithmic framework applicable to designing various business process changes such as process automation, business process resequencing, and more radical process integration. The framework follows dynamic programming approach in the literature, which is based on the decision making paradigm of organizations to abstract business processes as quantitative decision models. As such, our research ran fill the gap of limited development of theory based analytic methodologies for business process design, by providing objective rationale to reach the consensus among the organizational members including senior management.

본 연구는 장애아동 어머니가 겪는 편견 및 차별경험 극복과정을 분석하여 개선점을 모색하고자 한다. 이를 위해 장애아동을 양육하면서 편견 및 차별경험을 겪고 있는 장애아동 어머니 9명을 선정하여 인터뷰하였다. 자료 수집은 2018년 10월부터 11월까지 진행되었으며 반 구조화된 질문지를 활용하여 일대일 심층 면담을 하였다. 자료 분석은 수집한 자료를 근거로 현상을 기술하고 결론을 도출하는 귀납적 접근 방식인 합의적 질적 연구(Consensual Qualitative Research : CQR)방법을 통해 분석하였다. CQR 은 연구자들을 포함한 3명이상의 평정 자와 감사자로 구성된 합의 팀을 통해 연구의 전 과정에서 결과를 합의적으로 추론하게 되어 있어 연구자의 주관적인 오류를 방지하여 객관성과 일반화가 가능한 특징이 있다. 장애아동을 양육하면서 편견 및 차별경험과 극복과정을 CQR 분석한 결과 '장애아동 어머니의 편견 및 차별 경험', '장애아동 어머니의 차별 경험의 극복' 2개의 영역을 도출되었고, 그에 따른 7개의 하위영역, 28개 의 범주로 최종 구성되었다. 연구결과는 다음과 같다. 첫째, 장애아동 어머니가 장애아를 양육하면서 겪는 편견 및 차별경험은 일반아동과 장애아동을 비교하고 바라보는 사회적 시선이다. 잘못된 지각, 편견, 고정관념, 거부감으로 장애아동을 바라보기 보다는 장애아동을 이해하고 수용하는 태도로 장애아동으로 대하기를 원하는 것으로 나타났다. 둘째, 장애아동 어머니가 겪는 차별경험의 극복과정은 장애아동을 양육하면서 자신의 대한 인식의 심화 및 심리적 성장을 통해 타인에 대한 깊은 이해와 수용능력이 향상되는 것으로 나타났다. 이는 문제 상황에 대한 대처능력의 향상과 더불어 문제 상황을 바라보는 새로운 관점이 생기는 계기가 되었다. 이러한 내적 성장은 사회구성원의 편견 및 차별 등에 어려움을 겪더라도 가족 내의 결속력과 응집력이 강화되는 동기로 작동되었다. 연구의 결과를 근거로 장애아동 어머니 심리적 안녕 과 장애아동이 사회구성원으로서 건강한 생활을 할 수 있도록 실천적, 정책적 함의를 제시하였다.
