Cross-lingual query expansion is usually based on the relationship among monolingual words. Bilingual comparable corpus contains relationships among bilingual words. Therefore, this paper proposes a method based on these relationships to conduct query expansion. First, the word vectors which characterize the bilingual words are trained using Chinese and Thai bilingual comparable corpus. Then, the correlation between Chinese query words and Thai words are computed based on these word vectors, followed with selecting the Thai candidate expansion terms via the correlative value. Then, multi-group Thai query expansion sentences are built by the Thai candidate expansion words based on Chinese query sentence. Finally, we can get the optimal sentence using the Chinese and Thai query expansion method, and perform the Thai query expansion. Experiment results show that the cross-lingual query expansion method we proposed can effectively improve the accuracy of Chinese and Thai cross-language information retrieval.

The purpose of this study is to examine the sociolinguistic competence of female marriage-immigrants through analyzing their free colloquial discourse. Because previous studies on female marriage-immigrants have not been performed based on the natural illocutionary data, an accurate diagnosis of their communication method will be necessary for the efficiency of the Korean education aimed at them, and for the development of their communication ability. For this study, the colloquial discourse situation from five female marriage-immigrants from China, the Philippines and Vietnam was recorded. The sociolinguistic characteristics were analyzed centering on the use of designation, respect terms, and regional words. 'Eomma' was used as a designation for their husband's mother, which means that 'intimacy' worked for the designation of their husband's mother. The respect-word classes for others were limited to the 'haeyo' form and the 'hae' one, and the reception for listeners was often discarded. In addition, the influence of regional words was found in the vocabulary and grammar, and the more proficient the Korean language, the more frequent the regional word occurrence. Based on the above result, the teaching method of Korean for the immigrants shall be suggested as follows: the teaching has to focus on respect words positively influencing the relationship with the counterpart.

해방 이후 남북한 지리 교과서는 정치체제의 차이에 기인하여 각기 상이하게 발달하였다. 본 연구는 남한의 6차 교육과정의 중학교 사회와 고등학교 한국지리 및 세계지리 교과서 그리고 북한의 1995년 발간 지리 교과서를 자료로 남북한 교과서를 비교하고 분석하였다. 분석 결과, 남한 교과서는 탐구활동을 유도하는 학습자료, 표, 그래프, 사진 등을 수록한 반면에, 북한 교과서는 단순히 주제를 설명하는 내용과 스케치 및 다이어그램이 풍부하게 수록되어 있음을 알 수 있었다. 그리고 남한의 지리교과서는 인문지리와 지시 내용을, 북한의 지리교과서는 자연지리, 경제지리, 지도 학습을 강조하고 있다. 또한 지리 용어에서 남한 교과서는 한자어와 영미식 용어를 많이 사용하는 반면에, 북한 교과서는 상대적으로 순우리말로 된 용어를 많이 사용하고 있다. 통일 후 지리교육을 대비하기 위해서는 지리 교과서의 기술 체계와 내용 및 용어의 통일을 위하여 남북한 지리학자들과 지리교육자들의 접촉이 활발해져야 할 것이다.

The purpose of this experimental study was to investigate characteristics of English vowels uttered by Korean regional dialect speakers. Ten English mono-syllabic words, and eight Korean mono-syllabic words, were uttered six times by nine female graduate students from three areas: Seoul, Yongnam and Honam. Formant frequencies were measured from sound spectrograms made by the PC Quirer. Results showed that Seoul dialect speakers uttered English vowels more similar to those uttered by English native speakers than did the other dialect speakers. In particular, Yongnam dialect speakers have articulatory problems pronouncing the back vowels(/u/, /$\upsilon$/, /c/), while Honam dialect speakers have problems pronouncing the front vowels(/i/. /I/, /$\varepsilon$/, /$\ae$/). Even though each group has different problems pronouncing English vowels, Korean speakers generally have difficulty in discriminating tense vowels(/i/ and /u/) from the lax vowels(/I/ and /$\upsilon$/). It appears that the width of Korean speakers' articulatory movements is comparatively narrower than those of native English speakers.

This study aims to analyze the regional variations in which appear during the formation process of educational community in rural villages from the perspective of regional innovation theory. The study results revealed that the activities to form an educational community of the Songak village significantly influenced the variations across the social, economic and environmental aspects beyond an innovation of public education within the region based on interrelation between schools and villages. In other words, the activities including interactions and group learnings have been actively promoted among the various relevant stakeholders, thereby resulting in a variety of positive variations such as expanded regional welfare base, activated voluntary residents community gatherings based on the unity and cooperation, broadened socioeconomic opportunities, satisfaction on educational and cultural desires, and construction of healthy ecological environment in the region. Therefore, it is thought that regional development policy suitable for each region needs to be established by embracing the fact that activities to form a village educational community entail significant implication and value as the comprehensive regional innovation activities across the entire domains in each region.

Abnormal climate caused by climate change causes enormous social and economic damage. And such damage and its impact may vary depending on the location and regional characteristics of the region and the social and economic conditions of local residents. Therefore, it is necessary to continuously monitor whether there are indicators that are weaker than other regions among the detailed indicators that constitute the risk, exposure and vulnerability of climate change risk. In this study, the concept of climate change risk was used for heatwave to determine regional inequality of climate change risk. In other words, it was judged that inequality in climate change risk occurred in regions with high risk but high exposure and low vulnerability compared to other regions. As a result of the analysis, it was found that 13 local governments in Korea experienced regional inequality in climate change risk. In order to resolve regional inequality in climate change risks, the current status of regional inequality in climate change should be checked based on the analysis proposed in this study, there is a need for an evaluation and monitoring system that can provide appropriate feedback on areas where inequality has occurred. This continuous evaluation and monitoring-based feedback system is expected to be of great help in resolving regional inequality in climate change risks.

The one of the principles described in ICH E9 is that only results obtained from pre-specified statistical methods in a protocol are regarded as confirmatory evidence. However, in multi-regional clinical trials, even when results obtained from pre-specified statistical methods in protocol are significant, it does not guarantee that the test treatment is approved by regional regulatory agencies. In other words, there is no so-called global approval, and each regional regulatory agency makes its own decision in the face of the same set of data from a multi-regional clinical trial. Under this situation, there are two natural methods a regional regulatory agency can use to estimate the treatment effect in a particular region. The first method is to use the overall treatment estimate, which is to extrapolate the overall result to the region of interest. The second method is to use regional treatment estimate. If the treatment effect is completely identical across all regions, it is obvious that the overall treatment estimator is more efficient than the regional treatment estimator. However, it is not possible to confirm statistically that the treatment effect is completely identical in all regions. Furthermore, some magnitude of regional differences within the range of clinical relevance may naturally exist for various reasons due to, for instance, intrinsic and extrinsic factors. Nevertheless, if the magnitude of regional differences is relatively small, a conventional method to estimate the treatment effect in the region of interest is to extrapolate the overall result to that region. The purpose of this paper is to investigate the effects produced by this type of extrapolation via estimations, followed by hypothesis testing of the treatment effect in the region of interest. This paper is written from the viewpoint of regional regulatory agencies.

Purpose: In the 4th industrial revolution, services that incorporate various smart technologies in the tourism sector have begun to gain popularity. Accordingly, academic discussions on smart tourism have also started to become active in various fields. Despite recent research, the definition of smart tourism is still ambiguous, and it is not easy to differentiate its scope or characteristics from traditional tourism concepts. Thus, this study aims to analyze the perception of smart tourism exposed online to identify the current point of smart tourism in Korea and present the research direction for conceptualizing smart tourism suitable for the domestic situation. Research design, data, and methodology: This study analyzes the perception of smart tourism exposed online based on 20,198 news data from portal sites over the past six years. Data on words used with smart tourism were collected from the leading portal sites Naver, Daum, and Google. Text mining techniques were applied to identify the social awareness status of smart tourism. Network analysis was used to visualize the results between words related to smart tourism, and CONCOR analysis was conducted to derive clusters formed by words having similarity. Results: As a result of keyword analysis, the frequency of words related to the development and construction of smart tourism areas was high. The analysis of the centrality of the connection between words showed that the frequency of keywords was similar, and that the words "smartphones" and "China" had relatively high connection centrality. The results of network analysis and CONCOR indicated that words were formed into eight groups including related technologies, promotion, globalization, service introduction, innovation, regional society, activation, and utilization guide. The overall results of data analysis showed that the development of smart tourism cities was a noticeable issue. Conclusions: This study is meaningful in that it clearly reflects the differences in the perception of smart tourism between online and research trends despite various efforts to develop smart tourism in Korea. In addition, this study highlights the need to understand smart tourism concepts and enhance academic discussions. It is expected that such academic discussions will contribute to improving the competitiveness of smart tourism research in Korea.

Korean economy has experienced a very rapid growth largely due to the change of the innovation system since the last half century. The recent outbreak of COVID-19 impacts the global economy as well as Korea's innovation system. In order to understand the influence of the shock to the Korean technological system, we have forecast the future of the system combining qualitative and quantitative techniques such as expert panel, cross impact analysis, and scenario planning. According to the results, we have identified 39 driving forces influencing the change of Korea's technological innovation system. Four scenarios have been suggested based on the predetermined factors and core uncertainties. In other words, uncertainties of emergence of the regions and global value chains generate four scenarios: regional growth, unstable hope, returning to the past, and regional conflicts. The 'regional growth' scenario is regarded as the most preferable, whereas the 'regional conflicts' scenario is unavoidable. In conclusion, we put forward some policy implications to boost the regional innovation system by exploiting the weakened global value chains in order to move on to the most preferable scenario away from the return to the past regime.

본 논문의 목적은 한국어 표준어와 경상 지역 방언의 한국어 모음 발음의 영어 모음 발음에 대한 영향을 연구하는데 있다. 데이터 자료는 한국인의 영어 발음 음성 코퍼스(Korean-Spoken English Corpus, K-SEC)를 활용하였다. 이중 일곱 개의 한국어 단모음이 포함된 단어와 열 개의 영어 단모음이 포함된 단어가 선정되어 분석되었다. 선정된 자료는 외국 거주 경험이 없는 성인 남성 표준어 화자와 경상 지역 방언 화자에 의해 발화되었다. 녹음된 코퍼스 자료의 포먼트 주파수는 음성 분석 프로그램인 Praat에서 제공하는 스펙트로그램을 통해 측정되었다. 녹음된 자료들은 포먼트 구역 그래프로 나타내어 분석되었다. 결과에 의하면, 한국어와 영어 모음의 발화에서 경상 지역 방언 화자가 강한 후설성을 보인 반면에 표준어 화자는 비교적 전설성이 강하게 나타났다. 또한, 표준어와 경상 지역 방언의 한국어 모음 발음 차이 (/으/, /어/)는 대치되는 영어 모음 발음(/ə/, /ʊ/)의 조음 방식에 영향을 미쳤다. 지역 방언의 사용과 무관한 한국인의 일반적인 모음 발음 특징은 영어 원어민 화자보다 조음 구역이 좁다는 것이다. 이에 한국인은 전반적으로 긴장 모음과 이완 모음을 구별하는 데 어려움이 있지만, 영어 원어민 화자는 모음 조음에 명확한 구분이 있다.
