The purpose of this research is to create a preferable corporate culture under the SmartWork environment. There is growing interests in SmartWork, which can satisfy the compatible conditions of government's carbon emission restriction policy, corporate efficient expense reduction, productivity maximization, and each individual's work and a family. Due to the interests and the rapid development of IT technology, a realistic condition for SmartWork is established but the promotion without a sufficient preparation, such as legal examination and relevant systems, created much confusion and very few companies are introducing it. This paper discusses that a social agreement should be reached through adjustments among parties interested, such as government, companies, and employees, studies the WIN-WIN plan that individuals and organization can grow together, and proposes a new corporate culture under the SmartWork environment. SmartWork has more than the simple meaning of 'remote working'. SmartWork, a method of smart working, means a transition to a new paradigm that minimizes moving for work and work & human move together, and a change from a work-oriented culture to a human-oriented culture. This paper summarized the role of government and companies for the successful introduction of SmartWork, and proposed that a government level 'SmartWork Activation Executive Committee (tentative name)' with a strong promotional power would create a new culture of SmartWork and form a civilian consultative body to support SmartWork corporate culture creation & expansion in the private corporate area, in a tuning with Ministry of Public Administration & Security, Ministry of Labor, Ministry of Gender, and Communications Commission.

역량(capacity)이란 진술된 목표를 수행할 수 있는 능력을 의미하므로, 목표란 그 목표를 성취하기 위해서 요구되는 역량의 구체적 요소, 양, 질, 그리고 역량의 소재를 결정한다. 건강증진이란 문제를 파악하고 해결하기 위한, 그리고 조직이나 사람들이 그들의 목표를 성취하기 위한 응용과학으로 발전되어 왔다. 문제를 분석하고, 문제의 원인이나 결정요인들을 파악하고, 그리고 해결책을 제시하고 이를 실행하는데 있어 효과적인 방법론이 중요하다는 점도 또한 밝혀졌다. 그러므로 효과적인 건강증진의 토대가 되는 방법론은 건강을 증진을 위한 역량으로 정의될 수 있을 것이다. 목표는 매우 중요한 역할을 한다. 평균 기대수명을 향상시키는데 요구되는 능력은 생물학적인 그리고 행동적 건강위험을 감소시키는데 필요한 능력과는 다르다. 그리고 질병의 발생을 예방하고, 또는 상해를 예방하거나 모든 사람들이 좋은 건강상태를 얻고 유지하는데 동등한 기회를 갖는 환경을 조성하는 능력도 다른 특성을 지닌다. 방콕헌장은 현 단계의 건강증진을 위하여 건강에 대한 사회적 결정요인에 대한 해결책과 더불어 건강에 도움이 되는 사회적, 경제적, 그리고 물리적 환경을 조성하여 건강형평성을 달성하고자 하는 목표를 설정하고 있다. 지난 30년간 건강증진을 위한 역량에 대하여 많은 것들을 배울 수 있었다. 이러한 역량을 기르고 확대하는 것이 미래를 위한 도전과제가 되며, 비록 우리가 성취한 것이 많지는 않을지라도, 더 많은 것들이 필요하다는 점은 명백해졌다. 우리는 좀 더 야심 찬 목적을 가져야 하며, 이러한 목적달성을 위하려 좀더 의욕적인 노력을 해야 할 것이다. 전문분야로서 건강증진은 다른 사람들에 의하여 발생된 문제에 대한 대책이나 반응에만 중점을 둔 이방인으로서의 역할을 해왔다. 그러나 우리가 도전해야 할 과제는 좀 더 새롭고, 더욱 야심 찬 활동계획을 설정하고 우리가 건강해지고 건강을 유지하는데 필요한 생활환경, 작업환경, 여가환경, 영적 환경을 모든 사람들에게 제공할 수 있는 가족, 지역사회, 그리고 국가가 있는 세계를 만드는 우리사회의 능력들을 신장하는 것이다. 방콕 헌장은 건강증진을 위한 새로운 일련의 목표들을 제시하고 있다. 이제 이러한 목표를 성취할 수 있도록 역량을 기르는 것은 우리의 책임이 되었다. 이는 원하는 활동수준을 달성하기 위한 역량을 조율하고 확장시키는 것을 의미할 것이다. 구체적으로 기존의 건강증진효과성에 관한 증거들을 좀더 큰 규모의 사업으로 확대시키는 것, 공공정책을 개발하고 건강증진 상태를 평가하는 데 다양한 지역사회의 참여를 촉진시키는 능력, 언어, 인종, 성, 종교, 장애 등과 관련된 건강형평성의 문제를 파악하고 제거하는 노력, 그리고 정책결정과 인구집단의 건강과의 관련성에 대한 증거수집, 국가와 지역차원에서 사회적 의사결정 과정에의 적극적 참여, 다른 부문과의 건강증진을 위한 협력 등이 포함된다고 볼 수 있다. 본 논문은 방콕헌장을 분석함으로써 이러한 역량이란 무엇인가에 대한 본인의 의견을 제시하였다. 이러한 아이디어는 토론과 논쟁을 위하여 제시된 것이다. 명백한 것은 건강증진을 위한 역량은 전략이나 기술적인 능력 뿐 만이 아니라 정치적 능력이나 개인적인 능력도 포함된다는 점이다. 가치와 증거들이 정책이나 권력과 함께 결합되어야하며, 정치적인 논쟁 속에서 연마되어야 한다. 우리세계의 미래는 역량에 의존하기 때문이다.

This study aimed to examine conceptual discussions in transcription programs based on citizens' contribution and to discuss the operation and implications of the transcription program by investigating cases on transcribing records held in overseas archival institutions. With regard to conceptual discussions, the study identified the characteristics and significance of the transcription programs predicated on the notions of citizen archivists, participatory archives, and crowdsourcing. For case analysis, the study selected five transcription programs in the United States, the United Kingdom, and Australia, which are known to be managed successfully. The analysis was conducted following six criteria, including institution and goals, records for transcription, management of participation, infrastructure, policies and guidelines, and evaluation. The transcription programs were differentiated from community archives based on self-directed participation as the programs had a specific goal to improve access to historical records moderated by institutions. Therefore, it is necessary that strategies be built to attract the sustainable participation of the public. In this respect, the study made the following suggestions to domestic services similar to the cases. The purpose of a program needs to be described, and the topics, creators, and record types that could induce interests have to be considered when selecting transcription records. It is also important that a partnership is made with a small number of participants who made a significant contribution to the program and to provide interface and tasks for the transcription, which meet the participants' needs. In addition, it is necessary that simple and effective guidelines for transcription and policies be provided for use in transcription results, and that visible participants' contribution is recognized by applying the transcription results actively to search and access records.

This study aimed to explore the patterns of college students' dialogic argumentation in the context of nanotechnology issues, and to compare these patterns based on their idiocentrism and allocentrism. Nanotechnology represents the characteristics of socioscientific issues in that it is widely used in various fields, but at the same time, it includes the likelihood of negative effects. 33 college students who enrolled in science-related course participated in this study. Participants were divided into idiocentric groups and allocentric groups based on the INDCOL scores, and they participated in group discussions on nanotechnology. All discussions were audiotaped and analyzed using the framework of discourse clusters and schemes. Results showed that participating students engaged in dialogic argumentation with the process of exchanging of individual perspectives, exploration of different perspectives, and coordination and negotiation; specifically, they spent most of their time in exploring different values and perspectives regarding nanotechnology. Results also indicated the differences in discourse clusters and discourse schemes between idiocentric and allocentric groups. Allocentric groups more often negotiated to settle on a group decision than idiocentric groups did, and discourse schemes in their negotiation process were slightly different from the ones in idiocentric groups.

Conventional microgyroscopes of vibrating type require resonant frequency tuning of the driving and sensing modes to achieve high sensitivity. These tuning conditions depend on each fabricated microgyroscopes, even though the microgyroscopes are identically designed. A new micromachined resonator, which is applicable to microgyroscopes with self-toning characteristics, is presented. Since the laterally driven two degrees of freedom (2DOF) resonator was designed as a symmetric structure with identical stiffness in two orthogonal axes, the resonator is applicable to vibrating microgyroscopes, which do not need mode tuning. A dynamic model of the resonator was derived considering gyroscopic application. The dynamic model was evaluated by experimental comparison with fabricated resonators. The microgyroscopes were fabricated using a simple 2-mask-process of a single polysilicon layer deposited on an insulator layer. The feasibility of the resonator as a vibrating microgyroscopes with self-tuning capability is discussed. The fabricated resonators of a particular design have process-induced non-uniformities that cause different resonant frequencies. For several resonators, the standard deviations of the driving and sensing frequencies were as high as 1232Hz and 1214Hz, whereas the experimental average detuning frequency was 91.75Hz. The minimum detuned frequency was 68Hz with $0.034mVsec/^{\circ}$ sensitivity. The sensitivity of the microgyroscopes was low due to process-induced non-uniformity; the angular rate bandwidth, however, was wide. This resonator could be successfully applicable to a vibrating microgyroscopes with high sensitivity, if improvements in uniformity of the fabrication process are achieved. Further developments in improved integrated circuits are expected to lower the noise level even more.

테라헤르쯔(terahertz: THz)파는 0.1~10 THz 의 범위로 적외선과 방송파 사이에 광대역 주파수 스펙트럼을 차지하고 있으며 직진성, 투과성, 그리고 낮은 에너지 (meV)를 가지고 있어 비 파괴적이고 무해한 장점을 지니고 있다. Ti:sapphire laser와 같은 femto-pulse source 등이 많은 발전이 되어 현재 많은 연구와 발전이 이루어지고 있다. femto-pulse source를 이용한 THz 응용에서는 높은 저항, 큰 전자 이동도, 그리고 아주 짧은 전하수명의 기판을 요구하는데 저온에서 성장한 (low-temperature grown : LT) GaAs는 격자 내에 Gallium 자리에 Arsenic이 치환 하면서 AsGa antisite가 발생하여 전하수명을 짧아지는 것을 응용하여 가장 많이 이용되고 있다. 현재 THz 응용분야에서 보다 작고 가격경쟁력이 있는 광통신을 이용한 THz photomixer등이 활발히 연구 하고 있다. 광섬유 내에서 손실과 분산이 최소값을 가지는 부분이 1.55 ${\mu}m$ 부근이고 In0.53Ga0.47As 기판을 이용하였을 때 여기에 완벽하게 만족하게 된다. 하지만 LT-InGaAs 의 경우 AsGa antisite로 인하여 carrier lifetime은 짧아지지만 높은 n-type 전하밀도를 가지게 된다. 이때 Be을 doping하여 전하밀도를 보상하여 높은 저항을 유지해야 하는데 Be의 활성화를 위해서는 열처리를 필요로 한다. 하지만 열처리를 하면 carrier lifetime이 길어지기 때문에 carrier lifetime과 저항을 적절히 조율해야 한다. 이는 물질자체의 특성이기 때문에 InGaAs는 GaAs보다 낮은 amplitude와 짧은 cut-off frequency를 가진다. 본 연구에서는 보다 높은 저항을 얻기 위하여 molecular beam epitaxy를 이용하여 semi-insulating InP:Fe 기판위에 격자 정합된 InGaAs:Be/InAlAs multi quantum well (MQW)를 온도별 ($250{\sim}400^{\circ}C$), 주기별 (50~150)로 성장을 하였고 이때 InGaAs layer의 Be doping level은 $2{\times}1018\;cm^{-3}$, Ex-situ annealing은 $550^{\circ}C$에서 10분으로 고정 하였다. THz 발생 실험에서는 InGaAs/InAlAs MQW은 4000 pA로 1,000 pA를 가지는 InGaAs epilayer보다 4배 높은 전류 신호를 얻을 수 있었고 모든 샘플이 2 THz에서 cut-off frequency를 가지고 있었다. THz 검출 실험에서는 LT-InGaAs:Be epilayer LT-InGaAs:Be/InAlAs, HT-InGaAs/InAlAs 샘플이 각각 180, 9000, 12000 pA의 전류신호를 가지고 있었고 모든 샘플이 2 THz에서 cut-off frequency를 가지고 있었다. HT-InGaAs/InAlAs MQW를 이용한 검출실험에서는 InGaAs layer가 defect free이지만 LT-InGaAs:Be/ InAlAs MQW 보다 높은 전류 신호를 얻을 수 있었다. 이는 InAlAs layer가 저항만 높이는 것뿐만 아니라 carrier trapping layer로써의 역할도 하는 것으로 사료된다.

컴퓨터의 사용이 일반화됨에 따라 데이타를 생성하고 수집하는 것이 용이해졌다. 이에 따라 데이타로부터 자동적으로 유용한 지식을 얻는 기술이 필요하게 되었다. 데이타 마이닝에서 얻어진 지식은 정확성과 이해성을 충족해야 한다. 본 논문에서는 데이타 마이닝을 위하여 퍼지 결정트리에 기반한 효율적인 퍼지 규칙을 생성하는 알고리즘을 제안한다. 퍼지 결정트리는 ID3와 C4.5의 이해성과 퍼지이론의 추론과 표현력을 결합한 방법이다. 특히, 퍼지 규칙은 속성 축에 평행하게 판단 경계선을 결정하는 방법으로는 어려운 속성 축에 평행하지 않는 경계선을 갖는 패턴을 효율적으로 분류한다. 제안된 알고리즘은 첫째, 각 속성 데이타의 히스토그램 분석을 통해 적절한 소속함수를 생성한다. 둘째, 주어진 소속함수를 바탕으로 ID3와 C4.5와 유사한 방법으로 퍼지 결정트리를 생성한다. 또한, 유전자 알고리즘을 이용하여 소속함수를 조율한다. IRIS 데이타, Wisconsin breast cancer 데이타, credit screening 데이타 등 벤치마크 데이타들에 대한 실험 결과 제안된 방법이 C4.5 방법을 포함한 다른 방법보다 성능과 규칙의 이해성에서 보다 효율적임을 보인다.Abstract With an extended use of computers, we can easily generate and collect data. There is a need to acquire useful knowledge from data automatically. In data mining the acquired knowledge needs to be both accurate and comprehensible. In this paper, we propose an efficient fuzzy rule generation algorithm based on fuzzy decision tree for data mining. We combine the comprehensibility of rules generated based on decision tree such as ID3 and C4.5 and the expressive power of fuzzy sets. Particularly, fuzzy rules allow us to effectively classify patterns of non-axis-parallel decision boundaries, which are difficult to do using attribute-based classification methods.In our algorithm we first determine an appropriate set of membership functions for each attribute of data using histogram analysis. Given a set of membership functions then we construct a fuzzy decision tree in a similar way to that of ID3 and C4.5. We also apply genetic algorithm to tune the initial set of membership functions. We have experimented our algorithm with several benchmark data sets including the IRIS data, the Wisconsin breast cancer data, and the credit screening data. The experiment results show that our method is more efficient in performance and comprehensibility of rules compared with other methods including C4.5.

A girder height limitation is the critical parameter for rapid construction of bridge deck and construction space limitation especially in urban area such as high population area and high density habitats. A standard post-tensioned I-shaped concrete girder usually demands relatively higher girder height in order to retain sufficient moment arm between compression force and tensile force. To elaborate this issue, a small U-shaped section with wide flanges can be used as a possible replacement of I-shaped standard girder. This prestressed concrete box girder allows more flexible girder height adjustment rather than standard I-shaped post-tensioned girder plus additional torsion resistance benefits of closed section. A 30m-long, 1.7m-high and 3.63m-wide actual small prestressed concrete box girder is designed and a laboratory test for its static behaviors by applying 6,200kN amount of load in the form of 4-point bending test was performed. The load-deflection curve and crack patterns at different loading stage are recorded. In addition, to extracting the dynamic characteristics such as natural frequency and damping ratio of this girder, several excitation tests with artificial mechanical exciter with un-symmetric mass are carried out using operational frequency sweep-up. Nonlinear finite element analysis of this 4 point bending test under monotonic static load is investigated and discussed with aids of concrete damaged plasticity formulation using ABAQUS program.
