It is important to decide processing unit in the large vocabulary speech recognition system we propose a Pseudo-Morpheme as the recognition unit to resolve the problems in the recognition systems using the phrase or the general morpheme. We implement a morphological analysis system and tagger for Pseudo-Morpheme. The speech processing system using this pseudo-morpheme can get better result than other systems using the phrase or the general morpheme. So, the quality of the whole spoken language translation system can be improved. The analysis-ratio of our implemented system is similar to the common morphological analysis systems.

현재 GPT-4와 같은 거대한 언어 모델이 기계 번역, 요약 및 대화와 같은 다양한 작업에서 압도적인 성능을 보이고 있다. 그러나 이러한 거대 언어 모델은 학습 및 적용에 상당한 계산 리소스와 도메인 특화 미세 조정이 어려운 등 몇 가지 문제를 가지고 있다. In-Context learning은 데이터셋에서 추출한 컨택스트의 정보만으로 효과적으로 작동할 수 있는 효율성을 제공하여 앞선 문제를 일부 해결했지만, 컨텍스트의 샷 개수와 순서에 민감한 문제가 존재한다. 이러한 도전 과제를 해결하기 위해, 우리는 Super In-Context Learning (SuperICL)을 활용한 새로운 방법론을 제안한다. 기존의 SuperICL은 적용한 플러그인 모델의 출력 정보를 이용하여 문맥을 새로 구성하고 이를 활용하여 거대 언어 모델이 더욱 잘 분류할 수 있도록 한다. Super In-Context Learning for Generation은 다양한 자연어 생성 작업에 효과적으로 최적화하는 방법을 제공한다. 실험을 통해 플러그인 모델을 교체하여 다양한 작업에 적응하는 가능성을 확인하고, 자연어 생성 작업에서 우수한 성능을 보여준다. BLEU 및 ROUGE 메트릭을 포함한 평가 결과에서도 성능 향상을 보여주며, 선호도 평가를 통해 모델의 효과성을 확인했다.

The Korean society has been dramatically changed in its population, with rapidly increasing number of multicultural families through international marriages. The objective is to investigate the dietary patterns as an acculturation for multicultural families in urban area. The research target was 89 marriage immigrant females in Daejeon, in whom 50.6 % was in their twenties and 49.4 % was in their thirties to forties. 39.3% of the subjects was from China and 28.1 % from Vietnam, which showed similar pattern to the ratio of marriage immigrants' homeland in Korea. As age goes higher, cultural adaptation in Korea was the integration pattern. Marriage immigrant females from Vietnam showed the highest rates of marginalization pattern as cultural adaptation. Moreover, those with longer marriage duration and with children tend to show higher rates of integration pattern. 'Food attitude', 'food diversity', and 'balance life' as eating behaviors are related with acculturation. In conclusion, the multicultural families in urban area showed integration acculturation patterns, which could be influenced by their socioeconomic factors, such as residence period and Korean language ability and food diversity as dietary patterns factors. Further study with a quantitative analysis is needed in order to understand the effect of dietary patterns on acculturation in the multicultural families.

This study aims to understand the background and characteristics of receiving Hallyu based on the cognitions and attitudes toward Korea and Korean culture in the Philippines. With the background of Business Hallyu and Cultural Hallyu between the two countries, this study conducted the Focus Group Discussion(FGI) research, literature research and analyzed the statistical resources. The economic and cultural exchanges between Korea and the Philippines have been increased by the effect of Hallyu, but the socio-cultural conflicts, such as Kopino issue, crimes related to Koreans have been also grown. Thus, the Hallyu research focused on the Philippines is necessary, and it will be a cruical variable to forecast the socio-cultural relationship between Korea and the Philippines. The FGI research recruited participants in both undergraduates in the Phillippines and the Filippino migrants in Korea. The FGI participants of each group shows the differences of cognitions, attitudes, and actions to consume Hallyu, and the participants of both groups agrees that experiences of contacting Koreans influence on understanding Korea and its culture. The FGI participants have tried to watching Korean dramas, learning Korean languages, and building relationships with Koreans in order to adjust Korean culture. In order to improve the relations between Korea and the Philipines, Hallyu needs to promote its values as the unique culture and also universal culture in the world. Korea should increase understanding of the Filippino culture to overcome cultural differences and make efforts on localize the Hallyu 3.0 in the Phillippines.

Psychological properties of learners have influence on learning behaviors in various ways. The purpose of this study was to examine how the goal orientation of learners affected the learning time distribution method. Regulatory focus and theories of intelligence were measured and manipulated in order to differentiate participants' goal-oriented state. Two variables are known to be key variables influencing learner's goal orientation, inducing the approach-avoidance strategy and mastery-performance oriented attitude. In the experiment, the control focus was divided into two groups based on the inclination test score (regulatory Focus Questionnaire, RFQ), and TOI(theory of intelligence) was temporally induced through manipulation to confirm the interaction between the two variables. Participants were able to determine the order of learning freely by learning a set of Spanish-Korean word pairs and then selecting the items they would like to re-learn. Word pairs consisted of difficult or easy items, and learners could learn the same word many times if they wanted to. In the results, promotion-incremental group showed allocating difficult word-pairs in early time.

In order to investigate variables related to the life satisfaction of women from the multi-cultural families, this study collected relevant studies and applied meta-analysis. As a result, it was found, first, their life satisfaction was between the small effect size and the moderate effect size, on the basis of the relevant variables and Cohen's standards(1992). Second, of the sub variables of their individual characteristic variable, Korean proficiency and nationality acquisition were found to be the small effect size. Third, of the sub variables of their psychological variable and multiple culture-related variable, the effect sizes of self-esteem and the receptive attitude towards multiple cultures were found to be between the moderate effect size and the large effect size. Fourth, the sub variables of their social support variable were found to be generally highly correlated with their life satisfaction. Fifth, the sub variables of daily life and spouse-related variables showed very low levels of effect size overall. This study suggested conclusions and limitations of the research based on the results of the above analyses.

Concern for patient safety underlies the need for interprofessional education (IPE). One way to measure the effectiveness of IPE is by measuring attitude change toward other healthcare professionals; however, there are currently no valid Korean tools to measure such a change in attitudes. Therefore, this study aims to develop and test a Korean version of the Interprofessional Attitudes Scale (IPAS). The original IPAS was translated into Korean according to the World Health Organization's guidelines after obtaining permission from the article's corresponding author. A total of 414 questionnaires were collected from third- and fourth-year medical and nursing students at four Korean institutions in December 2018. To analyze the validity of the Korean IPAS, exploratory and confirmatory factor analyses were conducted. Cronbach's α was used to evaluate reliability. Results from the exploratory factor analysis identified four functions: teamwork, community-centeredness, patient-centeredness, and respect for diversity. Significant cross-correlations were found among the four functions (r=0.438-0.631, p<0.001) along with overall reliability (Cronbach's α=0.929) and reliability of each subfactor (Cronbach's α=0.804-0.897). This study verified the validity and reliability of the Korean version of the IPAS, so this scale can be used in the future to measure the effectiveness of IPE in Korea.

This study was conducted to study the effect of acculturation on the permanent resident and naturalized citizens' mental health status. The Survey Data of Foreign Residents in Korea 2012 was utilized. Independent variable was the acculturation level, measured by the duration of life spent in Korea and the level of Korean proficiency. The dependent variable was the mental health outcome. Initially, acculturation showed protective effect on mental health of immigrants. But after adjustment of control variables, the effect of acculturation disappeared. This result does not converge into the general trajectory of mental health status among immigrants regarding the level of acculturation. The experience of discrimination had outstanding negative effect, which suggests policy inception point.

Speaker recognition is generally divided into speaker identification and speaker verification. Speaker recognition plays an important function in the automatic voice system, and the importance of speaker recognition technology is becoming more prominent as the recent development of portable devices, voice technology, and audio content fields continue to expand. Previous speaker recognition studies have been conducted with the goal of automatically determining who the speaker is based on voice files and improving accuracy. Speech is an important sociolinguistic subject, and it contains very useful information that reveals the speaker's attitude, conversation intention, and personality, and this can be an important clue to speaker recognition. The final ending used in the speaker's speech determines the type of sentence or has functions and information such as the speaker's intention, psychological attitude, or relationship to the listener. The use of the terminating ending has various probabilities depending on the characteristics of the speaker, so the type and distribution of the terminating ending of a specific unidentified speaker will be helpful in recognizing the speaker. However, there have been few studies that considered speech in the existing text-based speaker recognition, and if speech information is added to the speech signal-based speaker recognition technique, the accuracy of speaker recognition can be further improved. Hence, the purpose of this paper is to propose a novel method using speech style expressed as a sentence-final ending to improve the accuracy of Korean speaker recognition. To this end, a method called sentence sequencing that generates vector values by using the type and frequency of the sentence-final ending appearing in the utterance of a specific person is proposed. To evaluate the performance of the proposed method, learning and performance evaluation were conducted with a actual drama script. The method proposed in this study can be used as a means to improve the performance of Korean speech recognition service.
