본연구는 최신 IT 기술(인공지능, 빅데이터, 사물인터넷)이 제조업에 끼치는 영향에 대한 분석이다. 일본의 제조업을 대표하는 도요타 자동차가 2016년에 미국 실리콘 밸리에, 인공지능 기술에 관한 R&D 거점 회사를 설립했다. 미국기업은 물론, 일본에서도 최신 IT 기술에 관한 조직을 신설하는 기업이 증가하고 있다. 그러나, 구체적으로 어떻게 IT 기술을 접목시켜 경영에 활용하는가에 대해서는 사회과학적논의가 아직 불충분하다. 그래서 본연구는 최신 IT 기술이 제조업에 끼치는 영향에 관해, 서플라이 체인의 최전선인 일본의 물류기업 히타치물류가 타사와의 차별화를 위해 준비하고 있는 “스마트 로지스틱 (logistic 4.0)” 개발 사례를 통해서, 프로세스와 효과, 활용방법 등을 밝힌다. 더나아가 이러한 최신 IT 기술이 히타치물류 업무 프로세스에 미치는 영향도 분석했다. 스마트 로지스틱 (logistic 4.0)은 최신 IT 기술을 이용해, 물류기업에 있어 중점 개선사항이라고 생각되는 1) 창고ㆍ서플라이 체인의 설계와 활용, 2) 거점간 운송 최적화, 3) 창고작업 효율화, 4) 물류정보의 가시화, 5) 현장개선책에 긍정적 효과를 가져와, 결과적으로 히타치물류는 물류 서비스를 이용하는 고객들에게 스마트 로지스틱 4.0 을 활용한 제안이 가능하게 됐다. 그리고 이러한 스마트 로지스틱 (logistic 4.0) 도입은 고객에 제공하는 서비스의 진화뿐만이 아니라, 히타치물류의 기존 업무 프로세스의 변화에도 영향을 미치고 있음을 인터뷰 조사를 통해서 규명했다.

Simple formulations on circulant matrices with alternating Fibonacci

Sugi Guritman 대한수학회 2023 대한수학회논문집 Vol.38 No.2

In this article, an alternating Fibonacci sequence is defined from a second-order linear homogeneous recurrence relation with constant coefficients. Then, the determinant, inverse, and eigenvalues of the circulant matrices with entries in the first row having the formation of the sequence are formulated explicitly in a simple way. In this study, the method for deriving the formulation of the determinant and inverse is simply using traditional elementary row or column operations. For the eigenvalues, the known formulation from the case of general circulant matrices is simplified by considering the specialty of the sequence and using cyclic group properties. We also propose algorithms for the formulation to show how efficient the computations are.

Sugie Shim 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.65 No.7

Dirac coupled channel analyses are performed using the optical potential model for the highlyingexcited states that belong to the 2− gamma vibrational band for 800 MeV unpolarized protoninelastic scatterings from 20Ne. First-order vibrational collective models are used to obtain thetransition optical potentials to describe the high-lying excited vibrational collective states, andLorentz-covariant scalar and time-like vector potentials are used as direct optical potentials. Thecomplicated Dirac coupled channel equations are solved phenomenologically to reproduce the differentialcross section data by varying the optical potential and the deformation parameters andby using the minimum chi-square method. Relativistic Dirac coupled channel calculation is ableto describe the excited states of the 2− gamma vibrational band in 20Ne much better than thenonrelativistic coupled channel calculation, especially for the 2− and the 3− states of the band. The multistep excitation process via channel coupling with the 3− state is shown to be essential indescribing the excitation of the 2− state, and the pure direct transition from the ground state isdominant for the excitation of the 3− state at the 2− gamma vibrational band in 20Ne.

Practice and Evaluation of Blended Learning with Cross-Cultural Distance Learning in a Foreign Language Class: Using Mix Methods Data Analysis

( Sugie S. ),( Mitsugi M. ) 범태평양응용언어학회 2014 범태평양응용언어학회지 Vol.18 No.2

The Information and Communication Technology (ICT) utilization in Chinese as a "second" foreign language has mainly been focused on Learning Management System (LMS), digital material development, and quantitative analysis of learners`` grammatical knowledge. There has been little research that has analyzed the effectiveness of cross-cultural distance learning by the mixed methods. In this study, Chinese classes were instructed with blended learning which has three phases such as classroom teaching, Web-Based Training, and Cross-Cultural Distance Learning. This practice was based on an instructional design and a motivational design. This study aimed to explore the outcome of learning and learners`` experiences with the mixed methods. A quantitative analysis shows that Japanese students have already had high motivation from the beginning, and that learners who are anxious about communication skills have gained confidence through the interaction practices. As a qualitative analysis result, learners failed to communicate with Chinese students and felt that they lacked vocabulary, but experienced the use of Chinese in authentic contexts through the synchronous face-to-face interaction. They also improved in aggressiveness and motivation for learning Chinese. They fixed words and sentences which were learned in the classroom in the process of talking to different partners. All participants enjoyed the rare chance of interaction between young native speakers, and formed a positive impression of them.

SHAPE-SELECTIVE ISOPROPYLATION OF BIPHENYL OVER DEALUMINATED H-MORDENITES

Sugi, Y,Kim, J.H,Matsuzaki, T,Hanaoka, T,Kubota, Y,Tu, X,Matusmoto, M 전남대학교 촉매연구소 1993 촉매학술발표회 Vol.- No.10

Shape-selective alkylation using zeolitc is a useful way to introduce functional groups symmeetrically to aromatic hydrocarbons. One of important development on shape-selective catalysis achieved recently is the success in isopropylation of polynuclear aromatics, such as biphinyl and naphthalene over H-mordenite[1-5]. However, the mechanism of the catalysis related to solid acid sites and steric requirement in zeolite pores have not been fully understood. In this paper, we examine the isopropylation of biphenyland the ismerization of 4,4'-diisopropylbiphenyl over highly dealuminated H-mordenites, and discuss the mechanism of the catalysis.

Dirac Phenomenological Analyses of 1.047-GeV Proton Inelastic Scatterings from 62Ni and 64Ni

Sugie Shim 한국물리학회 2018 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.73 No.11

Unpolarized 1.047-GeV proton inelastic scatterings from the Ni isotopes 62Ni and 64Ni are analyzed phenomenologically employing an optical potential model and the first-order collective model in the relativistic Dirac coupled channel formalism. The Dirac equations are reduced to Schrodingerlike second-order differential equations, and the effective central and spin-orbit optical potentials are analyzed by considering the mass-number dependence. The multistep excitation via the 2+ state is found to be important for the 4+ state excitation in the ground state rotational band for proton inelastic scatterings from the Ni isotopes. The calculated deformation parameters for the 2+ and the 4+ states of the ground state rotational band and for the first 3 state are found to agree pretty well with those obtained from nonrelativistic calculations.

Dirac Coupled-channel Analyses of the High-lying Excited States at 22Ne(p,p0)22Ne

Sugie Shim,Moon-Won Kim 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.67 No.12

Dirac phenomenological coupled-channel analyses are performed by using an optical potential model for the high-lying excited vibrational states at 800-MeV unpolarized proton inelastic scatterings from 22Ne nucleus. Lorentz-covariant scalar and time-like vector potentials are used as direct optical potentials, and the first-order vibrational collective model is used for the transition optical potentials to describe the high-lying excited vibrational collective states. The complicated Dirac coupled-channel equations are solved phenomenologically by using a sequential iteration method by varying the optical potential and the deformation parameters. Relativistic Dirac coupled-channel calculations are able to describe the high-lying excited states of the vibrational bands in 22Ne clearly better than the nonrelativistic coupled-channel calculations. The channel-coupling effects of the multistep process for the excited states of the vibrational bands are investigated. The deformation parameters obtained from the Dirac phenomenological calculations for the high-lying vibrational excited states in 22Ne are found to agree well with those obtained from the nonrelativistic calculations using the same Woods-Saxon potential shape.

Shape - Selective Alkylation of Biphenyl Catalyzed by H-Mordenites

Sugi, Yoshihiro 한국화학공학회 2000 Korean Journal of Chemical Engineering Vol.17 No.1

Liquid phase alkylation of biphenyl was studied over large pore zeolites. Selective formation of the narrowest products, 4,4'-diisopropylbiphenyl (4,4'-DIPB), occurred only over HM among the zeolites with twelvemembered pore openings. These shape-selective catalyses are ascribed to steric restriction of transition state and to entrance of bulky substrates into the pores. The dealumination of HM enhanced catalytic activity and the selectivity of 4,4'-DIPB because of the decrease of coke-deposition, while the activity and the selectivity were low over HM with the low SiO₂/Al₂O₃ ratio. Non-regioselective catalysis occurs on external acid sites because severe cokedeposition deactivates the acid sites inside the pores by blocking pore openings. The selectivity of DIPB isomers was changed with propylene pressure and/or with reaction temperature. 4,4'-DIPB yielded selectively under high propylene pressure ($lt;0.3 MPa) at 250℃, while the selectivity of 4,4'-DIPB decreased under such low propylene pressure as 0.2 MPa. Selective formation of 4,4'-DIPB was observed at moderate temperature such as 250℃, whereas the decrease of the selectivity of 4,4'-DIPB occurred at higher temperature as 300℃. However, 4,4'-DIPB was almost exclusively isomer in the encapsulated DIPB isomers inside the pores under every pressure and temperature. These decreases of the selectivity of 4,4'-DIPB are due to the isomerization of 4,4'-DIPB on the external acid sites. The deactivation of external acid sites of HM was examined to reduce non-regioselective alkylation and isomerization. External acid sites were deactivated by calcination after impregnation of cerium on HM without the decrease in pore radii. Selectivities of 4,4'-DIPB were improved even at high temperatures in the isopropylation of biphenyl because of the suppression of non-regioselective alkylation and isomerization at the external acid sites. The selectivity of 4,4'-diethylbiphenyl (4,4'-DEBP) in the ethylation of biphenyl was much lower than that in the isopropylation. Among the DEBP isomers, 4,4'-DEBP has the highest reactivity for the ethylation to polyethylbiphenyls inside the pores, whereas the isopropylation of 4,4'-DIPB was negligibly low inside the pores. These differences are ascribed to the difference in steric restriction at the transition state composed of substrate, alkylating agent, and acid sites inside the pores.

Ryosuke Sugie KINFORMS 2018 Management Review Vol.13 No.2

In this research, externally acquired knowledge was used to study the process of forming new organizational routines. Specifically, based on Huber’s (1991) organization learning process, we analyzed the theory of knowledge absorption capacity and stickiness of information. We conducted a case study of F company, which acquired knowledge through M & A, and in the course of that process, we learned about the organization and clarified the process formed in the organizational routine of new product development. This study of organization learning was mainly simulation verified and makes a theoretical contribution to the concrete execution of analysis using actual corporate cases.
