The integrated environmental permit system is currently in operation online. It carries out various functions of postmanagement such as the submission of annual reports containing operations management data onto integrated management workplaces, the operation and management of emission facilities and prevention facilities, and the disclosure of information on the integrated permission. On the other hand, the integrated environmental permit system needs to perform various roles in order to stably manage and smoothly perform the permitting work. It is necessary to utilize this system to establish policies by using diverse operations management data onto integrated management workplaces collected in the integrated environmental permit system. This system can also play a role in improving the post-management system and user convenience after the permission review and approval processes. The integrated environmental permit system can be effectively used to set up the BAT-AEL because it collects all of the cross-media data and identifies the overall status of the workplace. In order to establish a post management system after the approval, it is necessary to provide performance management and performance evaluation functions as conditions of the permit after approval. In addition, a variety of support functions should be provided to enable the permission authority and the environmental expert examination agency to facilitate the review of permits. It will be necessary to provide an evaluation system and a proactive diagnostic function to determine whether permission conditions and permit emission standards will change in the future. Also, it is important to adopt an information exchange platform that can be used to collect the status data onto the workplaces; the platform can also be used as an information exchange site for technical working groups (TWG), and for collecting field experts' opinions.

The purpose of this study is to identify the difference between the current retention level and the required level of engineering students' career competency that they think they need based on their perceptions. Ultimately, the results of this study are used as basic data when designing the major/general education program and the curricular/extra-curricular career program. The task of this study is to identify the difference between the current retention level and the required level of engineering students' career competency. And based on this, it is to confirm the educational needs of engineering students for the career competency. For this purpose, literature research on career competency education in universities was reviewed in the theoretical background. Next, previous studies on career competency and sub-competence derived from career competency-related studies and detailed questions were analyzed. Based on this, an initial evaluation tool for career competency of engineering students was developed. Finally, through expert review, a career competency evaluation tool with a total of 43 items in 10 competency groups was developed. A career competency evaluation questionnaire was conducted for 197 engineering students who participated in the 2022 Engineering Education Festa, and as a result of the IPA analysis, 'global competency' was found to be the competency with the largest difference between importance and execution. Next, 'major job competency' and 'career development competency' appeared in order. Reflecting the results of this study, it is expected that mutually organic design of competency-based liberal arts curriculum and major curriculum that can cultivate global competency, major job competency, and career development capability will be carried out through learning activities and field practice.

피로는 개인의 능력을 저하되게 하여 업무 수행을 어렵게 하며, 피로가 누적되면 집중력이 저하되어 안전사고를 초래할 가능성이 증가하게 된다. 피로에 대한 자각은 주관적이나, 실제 현장에서는 피로의 수준을 정량적으로 측정할 필요가 있다. 기존 연구에서 피로 수준은 다원적 피로 척도와 같은 주관적 평가에, 생체신호 분석 등의 객관적지표를 추가하여 전문가의 판단으로 측정하는 방식이 제안되었으나, 이러한 방법은 일상생활에서 실시간으로 피로도를 평가하기 어렵다. 본 논문은 현장에서 녹음한 음성 데이터를 이용하여 실시간으로 작업자의 피로 수준을 판정하는 피로도 분류 모델에 관한 연구이다. 현장에서 수집한 음성 데이터를 이용하여 로지스틱 분류, 서포트 벡터 머신, 랜덤 포레스트 등의 기계학습 모델을 학습시킨다. 성능을 평가한 결과, 정확도가 0.677 ~ 0.758로 우수한 성능을 보여주었고, 이 중에서 로지스틱 분류가 가장 우수한 성능을 나타냈다. 실험 결과로부터 음성신호를 이용하여 피로도를 분류하는 것이 가능하다는 것을 알 수 있다.

Student research has been proposed as an educational strategy to fulfill the current requirements in basic medical education (BME) and to compatible with the self-directed development of professionalism. It is commonly accepted that the goals of student research are to develop the competencies of critical, reflective, and self-directed thinking; problem-solving; and creativity; as well as to acquire the skills necessary to search for information and analyze the literature; to cultivate the talent of mastering a specialized field through deeply intensified learning; and to establish close relationships between students and supervisors. To successfully implement student research, authorities on BME should to plan the procedure for the student research projects and allocate personal and material resources adequately in order to provide the opportunity for self-evaluation and reflection through the completion of daily records, to develop the habit of consistently evaluating one's own study, and to maintain a collegial relationship between students and supervisors by offering the proper feedbacks in a timely and consistent manner. In conclusion, despite several obstacles and difficulties in the establishment of successful student research projects, student research could provide students the motivation to develop themselves into expert academic researchers, and play a role in educating students to help solve patients' problems based on scientific evidence in the future.

This paper presents a method of using syntax and shallow semantic analysis for Vietnamese question generation (QG). Specifically, our proposed technique concentrates on investigating both the syntactic and shallow semantic structure of each sentence. The main goal of our method is to generate questions from a single sentence. These generated questions are known as factoid questions which require short, fact-based answers. In general, syntax-based analysis is one of the most popular approaches within the QG field, but it requires linguistic expert knowledge as well as a deep understanding of syntax rules in the Vietnamese language. It is thus considered a high-cost and inefficient solution due to the requirement of significant human effort to achieve qualified syntax rules. To deal with this problem, we collected the syntax rules in Vietnamese from a Vietnamese language textbook. Moreover, we also used different natural language processing (NLP) techniques to analyze Vietnamese shallow syntax and semantics for the QG task. These techniques include: sentence segmentation, word segmentation, part of speech, chunking, dependency parsing, and named entity recognition. We used human evaluation to assess the credibility of our model, which means we manually generated questions from the corpus, and then compared them with the generated questions. The empirical evidence demonstrates that our proposed technique has significant performance, in which the generated questions are very similar to those which are created by humans.
