본 논문의 주된 연구목적은 인구이동이 인구재분포에 미치는 영향력을 분석하기 위한 방법론적 토대를 공고히 하고, 그것을 바탕으로 우리나라 인구이동의 편향성 혹은 불균형성의 시공간적 역동성을 탐색하는 것이다. 방법론적인 측면에서, 인구이동 유효도 지수(MEI)가 순이동률(NMR)에 비해 보다 적절한 측도인 것으로 판단되었다. MEI는 NMR에 비해 측도로서의 타당도가 높으며, ‘소인구문제’로부터 상대적으로 자유롭고, 인구이동의 현재적 역동성을 파악하는데 상대적으로 유리한 것으로 평가되었다. 덧붙여 MEI는 NMR에 비해 스케일 확장성이 월등해 다중 스케일을 고려한 연구 프레임워크의 수립에 훨씬 유리한 것으로 판단되었다. MEI에 기반한 분석 프레임워크를 우리나라의 최근 25년간(1998~2022년)의 데이터에 적용하여 분석하였다. 연구 결과를 요약하면 다음과 같다. 첫째, 전역 스케일의 분석 결과, 지난 25년간 전역적 MEI 값이 대략 5~10% 안에서 변동하는 경향을 보였으며, 특정한 시계열적 패턴을 보여주었다. 둘째, 지역별 스케일 분석의 결과, MEI가 NMR에 비해 인구이동의 역동성을 파악하는데 더 적절한 도구라는 사실이 입증되었다. 셋째, 지역-특수적 스케일 분석의 결과, 특별･광역시별로 매우 독특한 인구 교환 양상의 패턴이 드러났으며, 스케일 확장성이라는 측면에서 MEI는 NMR에 비해 월등하다는 사실이 입증되었다. 넷째, 지역간 스케일의 분석 결과, 인구이동 편향성이 두드러진 플로들이 확인되었다. 본 연구에서 제시된 연구 프레임워크는 다양한 방향으로 확장될 수 있는데, 집단 개별화 연구, 다변량 기법의 적용, 보다 작은 공간단위의 연구 등이다.

Background: Technological developments have led to the creation of a mechanical device capable of providing a representative massage as a passive treatment. The use of mechanical massage offers the distinct advantage of being user-friendly and available for use at any given time. Objectives: To investigated present the outcomes of utilizing a massage bed on the range of motion (ROM) and pressure pain threshold (PPT) in patients diagnosed with chronic low back pain. Design: ABA design of a single case study. Methods: To measure the ROM of the subject's trunk flexion, extension, lateral flexion, and rotation, a tape measure and goniometer were utilized. Furthermore, PPT was measured using an electronic pressure pain meter. Baseline A and Baseline A’ periods were conducted for 5 consecutive days without intervention. Following the baseline periods, a massage bed intervention was administered for 1 hour daily for a total of 10 days during the Intervention B period. Daily assessments were performed, and the Intervention B period was conducted after the intervention. Results: The ROM effect was confirmed in trunk lateral flexion and rotation, while the PPT was effective in both L1, right L2, left L4, and left L5. Conclusion: The results of this study confirmed that the use of a massage bed improved the ROM and PPT in patients suffering from chronic back pain. Further randomized controlled trials involving a larger sample size are necessary to validate these findings.

Adopting a conversation analytic framework, this paper examined the delay and potential indeterminacy of teacher’s repetition as an other-initiated repair (OIR) strategy, which took place at the third turn of the Initiation-Response-Evaluation (IRE) sequence in one-on-one tutoring sessions. Tutor-tutee interactions for a Korean secondary student were transcribed and analyzed along with notes used in the class. Data showed that when repetition was used as an OIR strategy, it was delayed and inaccurate. The learner was sometimes unsure whether the teacher’s repetition constituted a repair initiation regarding her prior turn. Furthermore, the learner could not successfully recognize which part of the repeated phrase should be repaired. Prior studies have confirmed that repetition can promote learners’ interactions rather than simply highlighting error while also giving learners an opportunity to correct their errors themselves. However, the analysis in this paper suggests a potential risk associated with using repetition as an OIR strategy at feedback turn in instructional discourse.

In order to humanize and contextualize ESL/EFL learning, poetry writing has been suggested and considered as an effective strategy for meaningful literacy. However, there is a lack of empirical evidence for the pedagogical significance of poetry writing on language learning. To make up for the dearth of research about poetry writing, the present study explored to what extent a primary English language learner can express herself through poetry writing in an American classroom and the significance of poetry writing as meaningful literacy in ESL/EFL learning. Adopting a qualitative research approach, this small-scale case study conducted textual analyses of a young English language learner’s poetry works and in-depth interviews with her. Findings suggest that poetry writing encouraged the participant learner to express herself with her own voice, enhanced her L2 linguistic awareness, provided meaningful learning opportunities―authorship and readership―, and motivated the learner to overcome challenges as an English language learner. The present study contributes to the understanding of young English language learners’ poetry writing in the field.

The forms and demands of language learning are changing in the pandemic era. Learners no longer rely solely on a formal language curriculum. Instead, they are using various informal language learning (ILL) channels. Although informal language learning has been in the spotlight and is growing, more research on ILL is needed. In this study, ILL taking place through an online community was analyzed. Articles from the Korean learning community (r/Korean in Reddit) were collected, and the topic modeling technique, Latent Dirichlet Allocation, was conducted on the collected data. As a result, seven major topics were selected. The most common topics in all posts were issues faced by beginner learners, followed by vocabulary and sentence meanings, interest in Chinese characters and applications of Korean language skills, culture and daily life, translation, online learning materials, and Korean phonics. Through this, the interests of ILL learners and the characteristics of learners could be identified. Due to the nature of ILL, in which a formal curriculum does not exist, it was found that questions about general strategies for learning and questions that could not be solved in formal language education were most prominent. In addition, the characteristics of ILL learners who actively sought learning content and materials were also found.

모국어와 한국어를 번역하는 능력은 한국어 전공 외국인 학습자들에게 요구되는 핵심 역량이지만 지금까 지 다소 소홀하게 다루어진 경향이 있었다. 이에 본 연구는 외국인 학습자 대상 번역 수업의 내실을 기한다 는 목적에 따라 한국현대시 번역 활동의 한국어 교육적 의미를 확인하고 베트남 대학생의 번역 능력 향상을 위한 교육적 시사점을 도출한다. 번역이란 원문의 의미와 가치에 대한 폭넓은 ‘이해’를 바탕으로 번역문을 ‘집필’하는 작업으로 진행된다. 하지만 이 연구는 논의를 명확하게 하기 위하여 원문 텍스트의 이해가 번역 결과물에 주는 영향력을 확인하고 학습자가 정확하게 번역하게 도울 원문 이해 교육 내용을 도출하는 데에 초점을 맞추었다. 이 연구에서 제시한 시사점은 베트남인 학습자 80명이 <사평역에서>(곽 재구, 1983) 번역한 결과를 분석 고찰한 결과인바, 향후 대학에서 외국인 학습자 대상의 한국어 번역 강의 를 개설할 때 실질적으로 도움이 될 수업 내용을 안내할 것으로 기대한다.

Background: In order to improve the daily life of stroke patients, it is necessary to restore walking performance. Improving gait performance is one of the main goals for stroke rehabilitation. Objectives: To investigate the change in gait parameters through evaluation of one stroke patient before, during, and after wearing the weight vest. Design: A case study. Methods: This study is an ABA study design. In principle, one assessment per day (A1) was measured three times without wearing the weight vest. Intervention assessment (B) was performed 6 times while wearing the weight vest. The second baseline evaluation (A2) was measured three times with the weight vest removed again. Results: The gait speed was increased when the weight vest was removed than when the weight vest was worn. Also, gait symmetry increased when wearing the weight vest. Conclusion: Wearing the weight vest can reduce the gait asymmetry in stroke patients and increase the gait speed after wearing the weight vest.

This study aimed to determine if animal-assisted therapy could enhance language and social interactions in autistic children. It is a single case study of a 6.7-year-old child diagnosed with second-rate autism disorder with a program of twelve sessions in total, a session per week, and fifty minutes per session. The program was constructed to increase the frequency of using words and to improve interpersonal relationships through contact with peers or strangers. To do this, SCAR and E-CLAC scales went through a pretest and posttest and the changes in main behaviors observed during the twelves sessions were analyzed, obtaining the following results: First, the animal-assisted therapy program allowed the autistic child to use daily words about twice more frequently than usual. Second, the animal-assisted therapy program was effective in allowing the autistic child to improve social interactions with peers or strangers around the dog. Therefore, the animal-assisted therapy program was effective in helping the autistic child enhance language and social interactions.

In this study, when a communication wire harness is defective due to long-term operation of a vehicle with a high-speed CAN communication network, the unique ID information of each controller and the oscilloscope waveform are analyzed to find defects. As a result of the experiment, it was possible to know whether the circuit of the main wiring was disconnected by the differential voltage analysis, and it was possible to confirm whether the sub-wiring was disconnected due to the generation of saw blade waveforms in the bus idle part. In addition, the fault location could be found with controller ID information and communication circuit analysis.

This paper attempted to analyze the correlation between the risk image of the evacuees in the tunnel and the variables that affect the evacuation behavior due to the closed feeling. As to whether there is a difference in the level of recognizing the tunnel risk image according to the distribution of jobs, the null hypothesis was rejected at the significance probability of 0.002, so it can be said that the level of recognition of the tunnel risk image varies depending on the job group. In the distribution difference between gender and tunnel risk image recognition level, the significance probability was 0.012, indicating that the null hypothesis was rejected, indicating that the tunnel risk recognition distribution according to gender was different. As a result of analyzing the distribution difference between the tunnel's closed feeling and the tunnel risk perception level, the significance probability was 0.001, and the null hypothesis was rejected, indicating that there was a difference in the tunnel risk image level.

해양환경의 위험유해물질 배출규제는 주로 선박이나 해양시설 등으로부터의 오염규제에 한정되어 있기 때문에, 해안 인접 산업 시설들의 위험유해물질 배출 허용기준 및 배출 지침 수립 등의 해양배출제도의 수립 필요성이 제기되고 있다. 본 연구에서는 해양산업시 설의 위험유해물질 배출 허용기준 및 배출 지침 정보를 자세히 제공하고 있는 미국 환경보호청(US EPA)의 자료를 중심으로 허용기준 및 배출 지침 수립 등 배출 제도 체계를 소개하고 향후 국내 배출지침 적용에 대해 고찰했다.

Safety has once again emerged as a social issue due to the enforcement of the Serious Disasters Punishment Act and the occurrence of major disasters recently. As such, the safety culture related to unsafe human behavior is drawing attention as various discussions about the importance of safety and accident prevention are currently being undertaken. This study aims to determine whether changes in the level of safety culture in companies affect the accident rate. To this end, we targeted three workplaces in the same company in the domestic manufacturing industry, and 2,790 people were surveyed using DNV's Safety Will(ISRS-C version 4.0) for safety culture level diagnosis. The change in safety culture level and accident rate were compared and analyzed after carrying out safety culture level improvement activities for 5 years. As a result, the level of safety culture increased by 5.8 points, an overall improvement of 9.5%, while the total number of accidents decreased by 20%, from 5 to 4, indicating a general decreasing trend in accident occurrence. Results confirmed that the change in the level of safety culture affects the accident rate, and the improvement in the level of safety culture affects a reduction in accidents. Therefore, this study suggests that efforts to improve the level of safety culture within a company can be associated with accident reduction and accident prevention outcomes.

As the uncertainty of technology development and market needs increases due to changes in the global business environment, the interest and demand for R&D activities of individual companies are increasing. To respond to these environmental changes, technology commercialization players are paying great attention to enhancing the qualitative competitiveness of R&D. In particular, R&D companies in the marine and fishery sector face many difficulties compared to other industries. For example, the R&D environment is barren, it is challenging to secure R&D human resources, and it is facing a somewhat more difficult environment compared to other sectors, such as the difficulty in maintaining R&D continuity due to the turnover rate of researchers. In this study, based on the empirical data and patent status of private companies closely related to the R&D technology status, big data analysis, and simulation analysis methods were used to identify the relative position of individual companies' R&D capabilities and industrial perspectives. In this study, based on industrial evidence and patent applications closely related to the R&D technology status, the R&D capabilities of individual companies were evaluated using extensive data analysis and simulation analysis methods, and a statistical test was performed to analyze if there were differences in capabilities from an industrial point of view. At this time, the industries to be analyzed were based on all sectors, the maritime industry, the fisheries industry, and the maritime industry integration sector. In conclusion, it was analyzed that there was a certain level of difference in the R&D capabilities of individual companies in each industry sector, Therefore when developing a future R&D capability system, it was confirmed that it was necessary to separate the population for each industry and establish a strategy.
