본 연구는 의사소통의 관점에서 고도의 설득적 언어형식을 담은 광고콘텐츠의 암묵적 의미와 그 해석 과정을 의사소통 교육과 관련하여 논의하고 동시에 현대사회의 미디어 리터러시 교육을 위한 해석적 코드를 마련하는데 논의의 목적을 가진다. 성공적인 논의를 위해 필자는 특별한 목적을 구현하는 광고콘텐츠의 서사적 내용을 일반적인 대화행위로 가정하고, 내포된 암묵적 의미 표현에 대한 규칙성이 존재함을 새롭게 문제제기로 밝혔다. 또한 현 사회의 미디어 리터러시 교육이 올바르게 진행되기 위해선 선행연구의 의사소통의 원리로 암묵적 의미에 대한 언어적 해석을 지도할 수 없음을 밝혔다. 해결방안으로 사회 문화적 공유 지식과 인지가 필수적인 해석 코드임을 확인하였다. 확장된 논의를 위해 언어사용적인 면에서 특수한 목적을 지닌 광고미디어언어를 분석대상으로 하여 그 속에 나타난 암묵적 의미의 해석 과정을 검증하였다. 필자가 임의적으로 유형화시킨 암묵적 광고언어를 분석한 결과, 화자가 설득할 의도로 암묵화한 언어적 의미는 다양한 정보 및 인지효과에 의한 분석의 틀로 대부분 미디어 리터러시 교육으로 제공될 수 있음을 확인하였다. 즉 수용자들은 미디어 언어에 내재된 암묵적 의미를 해석해 나가는 과정 속에서 글자 그대로의 해석만을 수행하지 않아야 한다. 모국어 자료 및 자신의 배경지식, 사회문화적 관습, 일반적인 공통지식 등을 포함시켜 지도한다면 효율적인 미디어 리터러시 교육의 성과를 기대할 수 있을 것이다.

본 논문에서는 관심주파수의 파장에 비하여 매우 섬세한 구조의 해석에 있어서 기존의 FDTD보다 효율적인 해석이 가능한 ADI-FDTD의 분산오차에 대하여 연구하였다. 2-D ADI-FDTD에 적합한 분산식을 제안하였으며 기존의 분산식들과 비교하였다. 수치적인 해석을 통하여 제안된 2-D ADI-FDTD 분산식이 수치결과와 일치함을 확인하였다.

This describes a numerical method for predicting the incompressible unsteady laminar three-dimensional flows of fluid behaviour with free-surface. The elliptic differential equations governing the flows have been linearized by means of finite-difference approximations, and the resulting equations have been solved via a fully-implicit iterative method. The free-surface is defined by the motion of a set of marker particles and interface behaviour was investigated by way of a 'Lagrangian' technique. Using the GALA concept of Spalding, the conventional mass continuity equation is modified to form a volumetric or bulk-continuity equation. The use of this bulk-continuity relation allows the hydrodynamic variables to be computed over the entire flow domain including both liquid and gas regions. Thus, the free-surface boundary conditions are imposed implicitly and the problem formulation is greatly simplified. The numerical procedure is validated by comparing the predicted results of a periodic standing waves problems with analytic solutions or experimental results from the literature. The results show that this numerical method produces accurate and physically realistic predictions of three-dimensional free-surface flows.

In this paper we introduce and consider a new class of variational inequalities with four operators. This class is called the extended general mixed quasi variational inequality. We show that the extended general mixed quasi variational inequality is equivalent to the fixed point problem. We use this alternative equivalent formulation to discuss the existence of a solution of extended general mixed quasi variational inequality and also develop several iterative methods for solving extended general mixed quasi variational inequality and its variant forms. We consider the convergence analysis of the proposed iterative methods under appropriate conditions. We also introduce a new class of resolvent equation, which is called the extended general implicit resolvent equation and establish an equivalent relation between the extended general implicit resolvent equation and the extended general mixed quasi variational inequality. Some special cases are also discussed.

There are differences in preference according to the brand signal explicitness when selecting fashion luxury brand, and the purpose of this study is to verify the moderating effects of self-construal and implicit theory in relation to those preferences. This study divided the experiment design into two $2{\times}2$ mixed design studies: Study 1 and Study 2. The study 1 was composed of the following factors: brand signal explicitness(subtle vs. explicit signal) and self-construal(independent vs. interdependent self-construal). Study 2 was composed of the following factors: brand signal explicitness( subtle vs. explicit signal) and Implicit theory(entity vs. incremental theorist). Convenience sampling was conducted to find the subjects of study 1 and study 2. Study 1 analyzed data from 172 women in Seoul, Gyeonggi-do and Busan who prefer luxury brand, and study 2 used data from 138 women. The results of this study are as follows. 1) Independent self-construal primed group was shown to prefer subtle signal product to explicit signal product, whereas interdependent self-construal priming group preferred explicit signal product to subtle signal product. 2) The entity theorist to prefer explicit signal product to subtle signal product. On the other hand, the incremental theorist did not show significant difference in the preference between subtle and explicit signal products. Therefore, the results of the present study shown the importance of understanding consumers through the difference depending on consumer inclination and psychology, recommending preferred luxury brand according to the inclination of the target customers, and establishing segmented marketing strategy to captivate consumers with these various characteristics.

Causality mining in NLP is a significant area of interest, which benefits in many daily life applications, including decision making, business risk management, question answering, future event prediction, scenario generation, and information retrieval. Mining those causalities was a challenging and open problem for the prior non-statistical and statistical techniques using web sources that required hand-crafted linguistics patterns for feature engineering, which were subject to domain knowledge and required much human effort. Those studies overlooked implicit, ambiguous, and heterogeneous causality and focused on explicit causality mining. In contrast to statistical and non-statistical approaches, we present Bidirectional Encoder Representations from Transformers (BERT) integrated with Multi-level Feature Networks (MFN) for causality recognition, called BERT+MFN for causality recognition in noisy and informal web datasets without human-designed features. In our model, MFN consists of a three-column knowledge-oriented network (TC-KN), bi-LSTM, and Relation Network (RN) that mine causality information at the segment level. BERT captures semantic features at the word level. We perform experiments on Alternative Lexicalization (AltLexes) datasets. The experimental outcomes show that our model outperforms baseline causality and text mining techniques.

In this paper, we have established some common fixed point theorems for two pairs of occasionally weakly compatible hybrid maps sat-isfying a strict contractive condition in a non-archimedean fuzzy metric space. Our result extend, generalized and fuzzify several fixed point theo-rems on metric space.

In this paper a general fixed point theorem for two pairs of mappings involving altering distance is proved. This theorem generalizes Theorem 9 [5], Theorems 1, 2, 3 [6], Theorems 2.3, 2.4 [7] and other results from [11]. As applications, some results for mappings satisfying contractive conditions of integral type and ${\phi}$-contractive conditions are obtained.
