본 연구의 목적은 인지과학의 관점에 근거하여 한국어 맛 어휘, 특히 한국어 맛 형용사의 분류 체계를 제안하는데 있다. 이때 한국어 맛 형용사의 분류는 인지과학의 분과 학문들이 수용하는 '미각'과 '향미'와 '맛'의 정의에 근거하여 이루어진다. 국내에서는 맛 어휘와 관련하여 많은 연구가 이루어져 왔다. 그래서 맛 어휘의 분류와 관련된 연구 결과물들이 꾸준히 발표되었으나, 연구자에 따라 크고 작은 차이를 보인다. 이는 연구자들이 맛 어휘를 범주화하는데 있어 객관적이고 보편적인 기준보다는 주관적이고 직관적인 기준을 적용했기 때문이다. 우리가 일상생활에서 흔히 말하는 '맛'은 미각 수용기 세포가 지각하는 감각 이상의 것을 포괄한다. 게다가 우리 인간이 지각하는 맛의 80~90%는 냄새에 좌우되어, 맛의 지각에 있어 후각의 중요성이 강조된다. 한편 음식의 식감과 색상과 온도, 음식을 먹는 주변 환경, 음식을 먹는 사람의 개인적 사회문화적 기호척도 등이 맛 지각에 큰 영향을 미친다. 먹는 것과 맛을 보는 것은 우리의 일상생활에서 중요한 부분을 차지한다. 그래서 맛 지각에 대한 언어학적 접근은 결코 간과할 수 없는 연구 영역이다. 본 연구자는 인지과학의 관점에 따른 맛 어휘의 분류가 맛 지각의 인지 메커니즘을 이해하는데 도움을 줄 수 있다는 가정에서 출발한다. 본 연구는 우리 인간의 심상어휘집에 '존재할 혹은 존재할지 모르는' 맛 어휘 낱말밭의 모습을 기하학적 모델로 형상화하고자 하는 후속 연구의 사전 작업임을 이 자리를 빌려 밝혀둔다.

This paper presents a study on the behavior of an RC bridge under near-field and far-field ground motions. For this purpose, a dynamic nonlinear finite element time history analysis has been conducted. The near-field and far-field records are chosen pairwise from the same events which are fits to the seismic design of the bridge. In order to perform an accurate seismic evaluation, the model has been analyzed under two vertical and horizontal components of ground motions. Parameters of relative displacement, residual displacement, and maximum plastic strain have been considered and compared in terms of near-field and far-field ground motions. In the following, in order to decrease the undesirable effects of near-field ground motions, a viscous damper is suggested and its effects have been studied. In this case, the results show that the near-field ground motions increase maximum relative and residual displacement respectively up to three and twice times. Significant seismic improvements were achieved by using viscous dampers on the bridge model. Somehow under the considered near-field ground motion, parameters of residual and relative displacement decrease dramatically even less than the model without damper under the far-field record of the same ground motion.

A regional wind network with complex surface conditions must be designed with sufficient space and time resolution to resolve the local circulations. In this study, the spatial variations of the wind field observed in the Seoul and Jeju regional networks were evaluated in terms of annual, seasons, and months to assess the spatial homogeneity of wind fields within the regional networks. The coherency of the wind field as a function of separation distance between stations indicated that significant coherency was sometimes not captured by the network, as inferred by low correlations between adjacent stations. A meso-velocity scale was defined in terms of the spatial variability of the wind within the network. This problem is predictably most significant with weak winds, dull prevailing wind, clear skies and significant topography. The relatively small correlations between stations imply that the wind at a given point cannot be estimated by interpolating winds from the nearest stations. For the Seoul and Jeju regional network, the meso-velocity scale has typically a same order of magnitude as the speed of the network averaged wind, revealing the large spatial variability of the Jeju network station imply topography and weather. Significant scatter in the relationship between spatial variability of the wind field and the wind speed is thought to be related to thermally-generated flows. The magnitude of the mesovelocity scale was significantly different along separation distance between stations, wind speed, intensity of prevailing wind, clear and cloudy conditions, topography. Resultant wind vectors indicate much different flow patterns along condition of contributing factors. As a result, the careful considerations on contributing factors such as prevailing wind in season, weather, and complex surface conditions with topography and land/sea contrast are required to assess the spatial variations of wind field on a regional network. The results in the spatial variation from the mesovelocity scale are useful to represent the characteristics of regional wind speed including lower surface conditions over the grid scale of large scale atmospheric model.

The bony notch on the inferior border of the mandible, anterior to the attachment of the masseter muscle, where the facial vessels commonly pass, has been called different names in the literature, e.g., premasseteric notch, antegonial notch, and notch for the facial vessels. Interestingly, various disciplines have leaned toward different names for this notch. Therefore, to aid in consistent communication among professionals, the present study aimed to analyze usage of these varied terms and make recommendations for the best terminology. Based on the adjacent anatomical structures used to name this notch, three groups were analyzed in this study, a group using masseter in the term, a group using gonion in the term, and a group using facial vessels in the term. A literature search found that the group using gonion in the term was found most in the literature. The orthodontics field used gonion in the term the most (29.0%: 31/107) followed by the oral and maxillofacial surgery field (14.0%: 15/107), the plastic surgery field (4.7%: 5/107), and the anatomy field (3.7%: 4/107). The dental field used gonion in this term the most (43.9%: 47/107) and the medical field used facial vessels in the term the most (33.3%: 6/18). Based on these results, the use of gonial terms for this notch seems to be preferred.

As the laws of physics are expressed in a manner that makes their invariance under coordinate transformations manifest, they should be written in terms of tensors. Furthermore, tensors make manifest the characteristics and behaviors of electromagnetic fields through inhomogeneous, anisotropic, and compressible media. Electromagnetic fields are expressed completely in tensor form, F^αβ, which implies both electric field ${\overrightarrow{E}}$ and magnetic field ${\overrightarrow{B}}$ rather than separately in the vector fields. This study presents the Mathematica platform that generates and transforms a second-rank antisymmetric field-strength tensor F^αβ and whiskbroom pattern in Minkowski space. The platforms enhance the capabilities of students and researchers in tensor analysis and improves comprehension of the elegant features of complete structure in physics.

An SOI LDMOS(Silicon-On-Insulator Lateral Double diffused MOSPET) with a tapered field plate is proposed and investigated in terms of the breakdown voltage and on-resistance using 2-D simulator, MEDICI. The results of conventional SOI LDMOS with a stepped field plate are reported for the comparison. Simulated breakdown voltage of the proposed LDMOS is found to be higher than that of conventional LDMOS since surface electric field can be reduced due to the field plate over the tapered oxide. On-resistance of proposed LDMOS is found to be lower than that of conventional LDMOS by 10%.

In this paper, the electric field distribution induced inside the brain during Transcranial Magnetic Stimulation(TMS) has been thoroughly investigated in terms of tissue heterogeneity and anisotropy as well as different head models. To achieve this, first, an elaborate head model consisting of seven major parts of the head has been built based on the Magnetic Resonance(MR) image data. Then the Finite Element Method(FEM) has been used to evaluate the electric field distribution under different head models or three different conductivity conditions when the head model has been exposed to a time varying magnetic field achieved by utilizing the Figure-Of-Eight(FOE) stimulation coil. The results show that the magnitude as well as the distribution of the induced field is significantly affected by the degree of geometrical asymmetry of head models and conductivity conditions with respect to the center of the FOE coil.
