In this study, we pursue a new direction for system modeling by introducing the concept of granular models, which produce results in the form of information granules (such as intervals, fuzzy sets, and rough sets). We present a rationale and several key motivating arguments behind the use of granular models and discuss their underlying design processes. The development of the granular model includes optimal allocation of information granularity through optimizing the criteria of coverage and specificity. The emergence and construction of granular models of type-2 and type-n (in general) is discussed. It is shown that achieving a suitable coverage-specificity tradeoff (compromise) is essential for developing granular models.

최근 전자 태그를 이용한 응용 서비스가 활성화됨에 따라 전자 태그의 데이터 처리에 대한 연구가 광범위하게 진행되고 있다. 따라서, 다양한 전자 태그로부터 수집된 객체 정보를 효율적으로 처리하기 위해 웹상에서 널리 사용되고 있는 XML 기반의 데이터 처리를 요구하고 있다. 이를 위해 EPCIS(EPC Information Service)는 EPC 관련 데이터를 공유하기 위한 표준인터페이스를 정의하였다. 현재 EPCIS 1.0 스펙의 Core Event Type은 EPC 네트워크에서 필요한 핵심타입들만을 정의하였고 적용 분야에 따른 비즈니스 context와 관련된 타입들은 정의하고 있지 않다. EPC 네트워크를 특정 비즈니스 영역에 적용할 때, Core Event Type 외에 추가적으로 정의해야 할 정보에 대한 타입 이 필요하다. 이에 본 논문에서는 이러한 비즈니스 영역에서 자주 사용되는 재사용 가능한 객체 타입을 정의하고 있다. 이렇게 정의한 객체타입과 EPCIS Spec에서 정의한 Core Event Type을 활용하여 해운 물류분야의 객체 정보 데이터 모델에 따른 스키마를 설계하였다.

The purpose of this study were to clarify differences in information processing type in relation to the consumer knowledge and involvement of apparel and to clarify differences in demographic characteristics in relation to the information processing type of consumer. The subjects of this study were female adults who lived in Seoul, Kyunggi or Incheon areas and Quota sampling using age and residential areas was employed. Major statistical methods were Chi square test and discriminant analysis. The results were as follows: 1. Consumer knowledge was found to be significantly related to the classification of information processing type. Low knowledge group tended to process infarmation rationally but high knowledge group utilized both rational and experiential process. 2. Consumer involvement was found to be significantly related to the classification of information processing type. Low involvement group tended to process information passively. High involvement group utilized both rational and experiential process 3. Information processing type was related to consumer's demographic characteristics such as age, education level, marriage, and purchase expense of apparel

본 논문에서는 $1.62{\times}1.0{\times}0.88mm^3$ 크기의 C-type과 $1.58{\times}0.82{\times}0.94mm^3$ 크기의 H-type RF 칩 인덕터를 제작하고 그들의 고주파 특성을 비교하였다. 본 연구에서는 저손실 $Al_2O_3$ 코아 물질과 직경 $40{\mu}m$의 구리(Cu) 코일을 사용하였다. 권선수를 $2{\sim}14$회로 하여 인덕턴스(L), 품질계수(Q), 임피던스의 크기와 위상, 커패시턴스(C)를 HP4291B Impedance/Material Analyzer로 측정하였다. 10회 권선시 C-type은 55nH, H-type은 67nH, 14회 권선시 C-type은 100nH, H-type은 122nH 정도로 측정되었다. 실험 결과 H-type이 C-type보다 동일 권선수에 대하여 높은 인덕턴스와 높은 자기공진주파수(SRF)를 나타냄을 확인하였다. 또한 최대 품질계수는 두 형태가 거의 비슷한 값($55{\sim}87$)을 가짐을 관찰하였다. 따라서 H-type이 C-type보다 우수한 성질을 나타냄을 알 수 있다.

본 논문에서는 라운드 함수의 업데이트 함수로 SP 구조를 사용하고 비밀 S-box가 적용된 GFN(Generalized Feistel Networks) Type I, Type II, Type III에 대한 안전성을 분석한다. 이 환경에서 공격자는 S-box에 대한 정보를 갖지 못한다. 인테그랄 공격 기법(Integral attack) 기반의 선택 평문 공격으로 9 라운드(Type I), 6 라운드(Type II), 6라운드(Type III)에 대한 비밀 S-box 정보를 복구할 수 있다. 선택 암호문 공격으로 전환할 경우 GFN Type I의 16 라운드까지 비밀 S-box의 정보가 복구된다. 결론적으로 m비트 비밀 S-box와 $k{\times}k$ MDS 행렬이 라운드 함수로 사용된 GFN Type I, Type II, Type III에 대하여 비밀 S-box를 복구하는데 ${\frac{2^{3m}}{32k}},{\frac{2^{3m}}{24k}},{\frac{2^{3m}}{36k}}$만큼의 시간복잡도가 필요하다.

Secondary accident is common type of accident which occurs in Korean highway tunnels. Fatality rate of secondary accidents in highway tunnels is six time higher than primary accidents. Video type VMS is a new way of providing information to road users which was recently introduced by Korean government to prevent secondary accidents in highway tunnels. In this study we compared changes in driver's behavior when information is provided by Text type and Video Type VMS. In addition to analyze effects of secondary accident reduction, driving behavior was analyzed based on providing advance information by video type VMS at tunnel entrance. Analysis showed that both text type and video type VMS has similar effect on driver behavior. Video type VMS showed positive effect on driver's behavior to prevent secondary accident when information is provided 1km ahead of accident. Considering there results and the short-term memory characteristics of driver, it was determined that information should be provide at about 650m from the entrance of the tunnel. The results of this study are consistent with the requirement that VMS should be installed at least 500m ahead of tunnel and produce more accurate providing information points. 650m is also appropriate interval for providing information in tunnel to cope with an accident ahead.

The purpose of this study is to research the influence of soundscape in the preference of landscape. Specifically, standards type of communication are applied to the landscape such as positive scenery and negative scenery. The spatial image was analyzed by the variables of Kaplan\`s information process model. The level of visual preferences was measured by a type of acoustic information and visual information in the landscape, and this data was analyzed by multiple regression. The results of this study can be summarized as follows; The value of landscape preference was maximum value in Type I and minimum value in Type II from all fluent of coherence, mystery, and legibility to, except complexity, and it was not different from preference. These results clearly show the influence of sounds effecting decision of landscape preference. It was different by the type of acoustic information and visual information in landscape. The results of ANOVA among types of acoustic information were differences of mean between positive sound, no sound and negative sound from coherence, mystery, and legibility to, except complexity. These variables may be the major factors which must be considered in planning and designing as the functional basis for quantitative analysis.

Surface permanent magnet-type vernier motors with three magnet array-type rotors (parallel magnetized type, repulsion type, and Halbach type) are compared based on the pull-out torque. It was clarified that increasing the rotor radius increases the pull-out torque at a fixed three-phase alternating voltage. The mechanism for the pull-out torque increase on each magnet array type was different, when the effects of the increase were analyzed based on an induced electromotive force and a synchronous reactance. As a result, the design of the Halbach-type rotor was found to be especially effective for achieving high pull-out torque, because this array type achieves a large induced electromotive force $E_0$ and a small synchronous reactance $x_s$.

기술 발달에 따른 기존 보안정책의 한계에도 불구하고 기업은 폐쇄적 보안정책을 유지함으로써 변화에 능동적으로 대응하지 못하고 있다. 본 연구는 정보보안 정책을 3가지 유형인 규제형 정책, 권고형 정책 그리고 고지형 정책으로 분류하였다. 분류된 각 정책의 유형은 확장된 계획행동이론을 적용하여 조직 구성원의 정보보안 정책 준수행동에 주는 영향을 규명하고 보안 스트레스의 조절효과를 살펴보았다. 각 요인들 간에 영향을 미치는 관계를 분석하기 위해서는 구조방정식모델링 기법인 SmartPLS 2.0과 SPSS 21.0을 활용하였다. 연구 결과 규제형, 권고형 그리고 고지형 정보보안 정책은 조직 구성원의 정보보안정책 준수행동에 영향을 주었으며 보안 스트레스는 계획된 행동이론의 선행요인인 정보보안 순응태도와 정보보안에 대한 주관적 규범에 영향을 주었다. 본 연구를 통해 기업의 정보보안 정책에 다양한 유형이 적용될 수 있음과 보안스트레스가 구성원의 정보보안 행동에 영향을 줄 수 있음이 제시되었다.

The purpose of this study was to analyze searching value types of Internet consumer information and to identify difference of information characteristics by searching value types. The online survey was conducted by 262 netizens. We used SPSS10.0 package and statistical analysis as follows : factor analysis, cluster analysis, one-way ANOVA, and Duncan's multiple range test. The results were summarized as follows: 1) searching value types of Internet consumer information were classified into 3 types - high benefit/high risk type, middle benefit/middle risk type, high benefit/low risk type. 2)In the degree of significance for information characteristics, consumer recognized accuracy as the most important then comes variability, utility, up-to-dateness, and reliability in that order. 3) high benefit/high risk type among searching value types was evaluated the most affirmative types for Internet consumer information.
