본 연구는 애니메이션 영화에서 빈번히 사용되고 있는 더빙 번역전략이 흥행에 미치는 영향을 스코포스 이론의 틀에서 실증적으로 연구 분석하였다. 한국영화진흥위원회의 2차 자료를 이용한 연구결과 더빙은 자막에 비해 매출액에 유의한 정(+)의 영향을 미쳤으며 이 영향은 성수기일 때, 연령등급이 낮을 때, 미국작품이 아닌 때 유의하게 더 높은 것으로 나타났다. 또한 연예인이 더빙에 참여했을 때 자막을 사용하거나 일반성우만이 참여한 경우보다 매출액이 유의하게 더 높은 것으로 나타났다. 이 결과는 스코포스의 이론에 기반한 번역전략인 더빙이 애니메이션의 관객을 고려할 때 자막보다 더 높은 품질의 번역이며 목표관객에 의해 더 선호되며 높은 매출로 이어진다는 것을 보여준다. 본 연구결과는 더빙의 긍정적인 영향을 사례분석에만 의존했던 기존의 연구와는 달리 실제 데이터를 이용해 실증적으로 검증하였다는 점에서 시사점이 있으며 향후 외국 애니메이션의 번역전략에 있어서도 목표관객의 특성 파악이 중요함을 시사한다.

The problem solving processes of elementary school children who are talented in science have been seldom studied. Researchers often resort to thinking aloud method to collect data of problem solving processes. The major purpose of the study is investigating high ability elementary school students' problem solving processes through the analysis of written responses to science problems in everyday context. 67 elementary students were participated Chungcheongbuk-do Elementary Science Contest held on October, 1997. The written responses of the contest participants to science problems in everyday context were analyzed in terms of problem solving processes. The findings of the research are as follows. (1) High ability elementary students use various concepts about air and water in the process of problem solving. (2) High ability elementary students use content specific problem solving strategies. (3) The problem solving processes of the high ability elementary students consist of problem representation, problem solution, and answer stages. Problem representation stage is further divided into translation and integration phases. Problem solving stage is composed of deciding relevant knowledge, strategy, and info..ins phases. (4) High ability elementary students' problem solving processes could be categorized into 11 qualitatively different groups. (5) Students failures in problem solving are explained by many phases of problem solving processes. Deciding relevant knowledge and inferring phases play major roles in problem solving. (6) The analysis of students' written responses, although has some limitations, could provide plenty of information about high ability elementary students' problem solving precesses.

Most existing wavelet-based multiplicative watermarking methods are affected by geometric attacks to a certain extent. A serious limitation of wavelet-based multiplicative watermarking is its sensitivity to rotation, scaling, and translation. In this study, we propose an image watermarking method by using dual-tree complex wavelet transform with a multi-objective optimization approach. We embed the watermark information into an image region with a high entropy value via a multiplicative strategy. The major contribution of this work is that the trade-off between imperceptibility and robustness is simply solved by using the multi-objective optimization approach, which applies the watermark error probability and an image quality metric to establish a multi-objective optimization function. In this manner, the optimal embedding factor obtained by solving the multi-objective function effectively controls watermark strength. For watermark decoding, we adopt a maximum likelihood decision criterion. Finally, we evaluate the performance of the proposed method by conducting simulations on benchmark test images. Experiment results demonstrate the imperceptibility of the proposed method and its robustness against various attacks, including additive white Gaussian noise, JPEG compression, scaling, rotation, and combined attacks.

Graphical user interface(GUI) has a very important role to interact with software users. However, designing and coding of GUI are tedious and pain taking processes. In many studies, the researchers are trying to convert GUI elements or widgets to code or describe formally their structures by help of domain knowledge of stochastic methods. In this paper, we propose the GUI elements detection approach based on object detection strategy using deep neural networks(DNN). Object detection with DNN is the approach that integrates localization and classification techniques. From the experimental result, if we selected the appropriate object detection model, the results can be used for automatic code generation from the sketch or capture images. The successful GUI elements detection can describe the objects as hierarchical structures of elements and transform their information to appropriate code by object description translator that will be studied at future.

The ongoing war between Russia and Ukraine increases concerns around the world. Russian President Vladimir Putin attacked Ukraine, with a clear aim to protect ethnic Russians from Ukraine, and further to keep Ukraine from joining NATO. However, as the war takes longer than expected, Russia is getting more isolated from the world. Given this, we analyzed editorials from the New York Times by paying attention to the newspaper's viewpoint or ideological stance to the war, under van Dijk (1998)'s ideological square within the framework of critical discourse analysis. The analysis results are as follows: first, Ukraine, the United States and the Europe were designated as the ingroup, whereas Putin was as its outgroup; second, the editorials used negative words for their outgroup presentation, highlighting the outgroup's bad properties, while the positive words for their ingroup presentations were rarely used, indicating that the editorials reinforce outgroup exclusion only; third, it was only Russian President Vladimir Putin who was in their outgroup, while Russians were depicted as scapegoats to satisfy the pleasures of the maniacal Putin. Thus, it can be concluded that with the strategy of negative exclusion, the editorials clearly show their negative ideology towards the war by using negative words for the outgroup almost six times as often as positive words for the ingroup.

문서의 제목은 문서의 내용을 가장 효율적으로 요약하여 제공해 준다. 이때 독자들이 선호하는 스타일과 언어에 따라 문서의 제목을 다르게 제공해 준다면, 독자들은 문서의 내용을 좀 더 쉽게 예측할 수 있다. 본 연구에서는 문서가 주어졌을 때 언어와 스타일에 따라 제목을 자동 생성하는'교차 언어 및 스타일 기반의 제목 생성 모델을 제안한다. 모델을 학습하기 위해서는 같은 내용을 다른 언어와 다른 스타일로 작성한 병렬데이터가 필요하다. 그러나 이러한 종류의 병렬데이터는 구축하기 매우 어렵다. 반면, 단일 언어와 단일 스타일로 구축된 제목 생성 데이터는 많으므로 본 연구에서는 제로샷(zero-shot) 학습으로 제목 생성을 수행하고자 한다. 교차 언어 및 스타일 기반의 제목 생성을 학습하기 위해 다중 언어로 사전 학습된 트랜스포머 모델에 각 언어, 스타일, 기계번역을 위한 어댑터를 추가하였다. 기계 번역용 병렬데이터를 이용하여 기계번역을 먼저 학습한 후, 동일 스타일의 제목 생성을 학습하였다. 이때, 필요한 어댑터만을 학습하고 다른 부분의 파라미터는 모두 고정시킨다. 교차 언어 및 스타일 기반의 제목을 생성할 때에는 목적 언어와 목적 스타일에 해당하는 어댑터만을 활성화시킨다. 실험 결과로는 각 모델을 따로 학습시켜 파이프라인으로 연결시킨 베이스라인에 비해 본 연구에서 제안한 제로샷 제목 생성의 성능이 크게 떨어지지 않았다. 최근 대규모 언어 모델의 등장으로 인한 자연어 생성에서의 많은 변화가 있다. 그러나 제한된 자원과 제한된 데이터만을 이용하여 자연어 생성의 성능을 개선하는 연구는 계속되어야 하며, 그런 점에서 본 연구의 의의를 모색한다.

Rehabilitation of historical unreinforced masonry (URM) buildings is a priority in many parts of the world, since those buildings are a living part of history and a testament of human achievement of the era of their construction. Many of these buildings are still operational; comprising brittle materials with no reinforcements, with spatially distributed mass and stiffness, they are not encompassed by current seismic assessment procedures that have been developed for other structural types. To facilitate the difficult task of selecting a proper rehabilitation strategy - often restricted by international treaties for non-invasiveness and reversibility of the intervention - and given the practical requirements for the buildings' intended reuse, this paper presents a practical procedure for assessment of seismic demands of URM buildings - mainly historical constructions that lack a well-defined diaphragm action. A key ingredient of the method is approximation of the spatial shape of lateral translation, ${\Phi}$, that the building assumes when subjected to a uniform field of lateral acceleration. Using ${\Phi}$ as a 3-D shape function, the dynamic response of the system is evaluated, using the concepts of SDOF approximation of continuous systems. This enables determination of the envelope of the developed deformations and the tendency for deformation and damage localization throughout the examined building for a given design earthquake scenario. Deformation demands are specified in terms of relative drift ratios referring to the in-plane and the out-of-plane seismic response of the building's structural elements. Drift ratio demands are compared with drift capacities associated with predefined performance limits. The accuracy of the introduced procedure is evaluated through (a) comparison of the response profiles with those obtained from detailed time-history dynamic analysis using a suite of ten strong ground motion records, five of which with near-field characteristics, and (b) evaluation of the performance assessment results with observations reported in reconnaissance reports of the field performance of two neoclassical torsionally-sensitive historical buildings, located in Thessaloniki, Greece, which survived a major earthquake in the past.

Purpose: Following legal reform in 2013, the annual number of asylum seekers entering South Korea has increased from 1,143 in 2012 to 5,711 in 2015. We interviewed six African refugee mothers of young children regarding their health needs and barriers to access maternal child health services. Methods: We recruited mothers who had visited a clinic for immigrants between July 2013 and August 2015. Participants were African refugee women, aged over 18 years, who had given birth in Korea within the previous 5 years and had come to Korea over a year before recruitment. Interview questions examined participants' experiences in pregnancy and childbirth and concerns regarding their child's health status. Initial data analysis involved all researchers' immersion in the entire collection of transcripts. We then noted recurrent topics and themes and identified similar issues. Results: At the time of giving birth, 5 participants were asylum seekers and one had undocumented status. The following barriers impeded their access to maternal child healthcare: socioeconomic factors (unstable social identity, low economic status, difficulty obtaining health insurance), language barriers (lack of linguistically appropriate health information, limited access to translation services), and cultural barriers (religious and cultural differences). Weak social support also hindered access to healthcare soon after migration; however, social links with the community emerged as a key coping strategy following settlement. Conclusion: We identified barriers to maternal and child healthcare and coping strategies among African refugee mothers in Korea. Future research should assess refugees' health status and improve health access and literacy among refugee mothers.

대부분의 함수형 프로그래밍 언어에서는 '위에서 아래쪽, 왼쪽에서 오른쪽 방향으로' 패턴 매칭(pattern matching)을 한다는 전략에 따라, 모호한(ambiguous) 특성을 갖는 룰의 정의를 허용하고 있다. 이 방법은 함수형 프로그래머에게 디폴트 룰을 정의할 수 있게 하는 직관적인 편리함을 제공하지만, 한편으로 모호한 룰 때문에 함수형 언어의 의미는 불명확해 질 수 있다. 좀 더 구체적으로, 함수형 언어가 갖는 대표적인 특성인 등식 추론(equational reasoning) 원리의 적용을 불가능하게 할 수 있으며, 함수형 언어를 람다 계산법으로 변환하는 데 있어서도 정형적인 방법이 아닌 임시방편적인(ad hoc) 방법에 의존할 수밖에 없게 한다. 본 연구에서는 지연(lazy) 함수형 언어의 패턴 매칭의 의미를 순수 선언적 특성을 갖는 항 개서 시스템(Term Rewriting Systems)의 분리성(separability) 이론과 연관시키고, 분리성 이론에 따라 지연 함수형 언어가 람다 계산법으로 변환될 수 있음을 보인다.

Vibration test on MAST(multi axial simulation table) system has several advantage over one-axial vibration test that could simulate 6-DOF, 3-axial translation and 3-axial moment, at the same time. Since field vibration motion can be fully represented with 6-DOF, multi-axial vibration test on vehicle component is widely conducted in technical leading companies to make sure its fatigue performance in vibration environment. On the way to fulfill the process, editing technique of obtained field data is key issue to success a reliable vibration testing with MAST system. Since the original signals are not only too large to fulfill it directly, but all of the measured data is not guarantee its convergency on generating its driving files, editing technique of the original signals are highly required to make some events that should meet the equal fatigue damage on the target component In this paper, key technique on editing a field data feasible for MAST system is described based on energy method in vibration fatigue. To explain its technique explicitly, author first introduced a process on field data acquisition of two vehicle component and then, representing events are produced to keep up with the editing strategy about a energy method. In the final chapter, a time information regarding a vibration test on MAST system is derived from the energy data which is critical information to perform a vibration test.
