In linguistics, stemming is the operation of reducing words to their more general form, which is called the 'stem'. Stemming is an important step in information retrieval systems, natural language processing, and text mining. Information retrieval systems are evaluated by metrics like precision and recall and the fundamental superiority of an information retrieval system over another one is measured by them. Stemmers decrease the indexed file, increase the speed of information retrieval systems, and improve the performance of these systems by boosting precision and recall. There are few Persian stemmers and most of them work based on morphological rules. In this paper we carefully study Persian stemmers, which are classified into three main classes: structural stemmers, lookup table stemmers, and statistical stemmers. We describe the algorithms of each class carefully and present the weaknesses and strengths of each Persian stemmer. We also propose some metrics to compare and evaluate each stemmer by them.

The purpose of this study was to propose ways to improve the library field practice of Department of Library and Information Science to improve the field environment and educational content, enhance students' field practice, increase efficiency, and increase students' satisfaction. To this end, a survey and interview survey were conducted on students who were going to do field training, and the results are as follows. First, students were well aware of what preparations should be made at school before going to field training. Second, students showed high awareness of their rights guarantees and requests for action in the event of problems at field training institutions. Third, students showed a high demand that field training should guarantee the minimum hourly wage. What is an issue in this regard is that policies that can satisfy both the burden of universities for continuous student guidance and evaluation, the burden of training institutions to conduct education while paying practical expenses, and the rights of students to be protected. This study was aimed at students, but it seems that realistic field practice policies should be presented from various angles as research on government ministries or university authorities is added.

This study attempted to grasp the current status of field training in the Department of Library and Information Science and the training institutions of the students of the Department of Library and Information Science and to propose a development plan based on this. To this end, a questionnaire survey and survey were conducted on the status of field practice in the Department of Library and Information Science at 4-year and 2-year colleges. As a result of the study, first, it was analyzed that field training has an effect on the employment competitive- ness and employment competency of students, and the field training environment has an effect on career decisions of students in the Department of Library and Information Science. Second, it was found that the library with the most field training was found to be a public library, and it was investigated that in order to allow students to experience various institutions and choose their career path, it was necessary to jointly discover and use field training institutes. Third, the evaluation contents or evaluators of the field training did not show a big difference by school, and it was found that most universities are evaluating the field practice using various scales. Lastly, in order to maintain the level of on-the-job training to some extent, it is necessary to develop a training manual and distribute it to each university.

The focus of this work is placed on the analysis of the mixture formation mechanism under the evaporative diesel spray of impinging and free conditions. As an experimental parameter, ambient gas density was selected. Effects of density variation of ambient gas on liquid and vapor-phase inside structure of evaporation diesel spray were investigated. Ambient gas density was changed between ${\rho}a=5.0\;kg/m^3$ and $12.3\;kg/m^3$. In the case of impinging spray, the spray spreading to the radial direction is larger due to the decrease of drag force of ambient gas in the case of the low density than that of the high density. On the other hand, in the case of free spray, in accordance with the increase in the ambient gas density, the liquid-phase length is getting short due to the increase in drag force of ambient gas. In order to examine the homogeneity of mixture consisted of vapor-phase fuel and ambient gas in the spray, image analysis was conducted with statistical thermodynamics based on the non-dimensional entropy (S) method. In the case of application of entropy analysis to diesel spray, the entropy value always increases. The entropy of higher ambient density is higher than that of lower ambient gas density during initial injection period.

The purpose of the paper is empirically to explore ‘design manner’, focusing on the designer’s knowledge boundary on the designer-user interactions in the design process. This study conducts a field study and observed designer’s interactions with actual users in a leading user-centered design firm over three months. The observations revealed how designers bring ideas about users into design without physically interacting with users during the design process. Based on Bourdieu’s theory of practice and the concept of boundary objects, this study introduces the concept of ‘design manner’, by which designers incorporate user’s ideas into the design process without actual involvement of users in the process. This paper contributes to the body of knowledge by introducing the design manner in-between designer’s and user’s knowledge boundaries and argue bridge between theoretical and actual designer-user interactions in the IS design process.

The accounting literature abounds with many studies concerning the organizational and technical aspects of the AIS to simulate progress in the business environment. However, few studies have focused on the role of individual factors in overcoming resistance to change and maximizing the value of using the system. Therefore, this study aims to shed light on user beliefs by evaluating the factors that affect the use of the AIS using a developed TAM. A total of 132 subjects participated in this study, in which the questionnaire was used as a data collection tool and AMOS was used to test the model. The results showed that subjective norm, training and experience were the most important previous factors that affect the perceptual factors represented in usefulness, ease of use and the inevitability of change, which all had an impact on the continuance intention to use the AIS among users in Algerian firms. This study shed light on the importance of assessing individual factors rather than focusing only on the ways to develop AIS or researching for new technologies and the costs of this investment because this will increase the chances of success in using the system.

본 연구는 산업현장에서의 응급의료 접근성에 영향을 미치는 구조적 요인을 규명하고, 현장 응급출동 사례를 바탕으로 개선방안을 제시하는 것을 목적으로 한다. 연구 대상은 대형 건설현장 내 저천장 협소 작업공간에서 발생한 응급출동 사례로, 해당 공간은 낮은 천장 높이, 구조물 밀집, 제한된 이동 환경의 특성을 가진다. 분석 결과, 해당 작업공간은 작업 수행에는 적합하였으나 응급상황 발생 시 구조대원의 접근성과 환자 이송을 고려한 설계는 충분히 반영되지 않은 것으로 나타났다. 주요 저해 요인으로는 저천장으로 인한 제한된 작업 자세, 안전고리 반복 체결로 인한 이동의 비연속성, 구조물에 따른 이동 경로 제한이 확인되었다. 이러한 요인은 구조대원의 접근 지연과 처치 및 이송 과정의 효율성 저하를 초래하는 것으로 나타났다. 본 연구는 작업 수행이 가능한 공간이 반드시 응급구조가 가능한 공간을 의미하지 않음을 확인하였다. 이에 따라 설계, 시스템, 기술, 제도, 운영 측면에서의 개선방안을 제시하였다. 제안된 방안은 건설현장뿐만 아니라 대규모 플랜트 현장 등 유사한 산업현장에서의 응급의료 접근성 향상에 기여할 수 있을 것으로 기대된다.

This study identifies structural factors affecting emergency medical accessibility in industrial sites and proposes improvements based on a field response case. The research focuses on a confined workspace in a large construction site, characterized by a low ceiling and dense structural obstacles. Findings reveal that while functional for tasks, the workspace was not adequately designed for emergency response. Key barriers included constrained working postures, discontinuous movement from repetitive safety hook transitions, and restricted access routes. These factors delayed responder access and hindered the efficiency of patient assessment and transport. The results emphasize that a space suitable for work does not inherently ensure effective emergency response. To address these challenges, this study proposes multi-dimensional improvements across design, system, technical, regulatory, and operational levels. These strategies are expected to enhance emergency accessibility in various industrial environments, including construction and large-scale plant facilities.

Over recent years, the study of self-regulation has replaced the study of learner strategies as it constitutes a process-oriented approach. The present study was an attempt to identify the Iranian EFL learners’ use of selfregulated vocabulary strategies (SRVS) in texts with L1 and L2 marginal glosses and those accompanied by technology-enhanced materials on the computer. The study also compared strategy use across gender, age, and field of study. There were three experimental groups in the study each of which received different type of vocabulary instruction. Experimental group 1 was taught new vocabulary items in the form of printed textual definition coupled with still pictures. Experimental group 2 was taught via marginal glosses in L1 and experimental group 3 was taught via marginal glosses in L2. All the participants were asked to fill out the self-regulating capacity in vocabulary learning scale (SRCvoc). The results of a one way ANOVA showed significant differences, and the Tukey post-hoc test showed that there was a significant difference only between the texts with still pictures and those with L1 and L2 marginal glosses. Regression analyses indicated that vocabulary strategy use was influenced by individual variables.

본 연구에서는 국가핵심기반 시설 중 식용수 분야 시설에서의 최대허용중단기간(MTPD) 산정 방안을 제시하고자 하였다. 현재 국가핵심기반 시설의 MTPD를 산정하는 방법은 중단 발생 시 시설에서 보유 하고 있는 활용 가능한 자원의 양과 복구 시간에 대한 내용이 포함되어 있으나 구체적인 기준 또는 방법론이 없는 실정이다. 국내·외 관련 선행연구 분석 및 사례연구를 분석하여 경제적 요소 중 부가가치 를 활용하여 MTPD를 판단할 수 있는 프레임워크를 확인 및 검증하였다. 해당 프레임워크 기반으로 국내 식용수 분야 시설 중 인천광역시 공촌정수장을 대상으로 추정치를 도출하여 적용 가능성을 판단 할 수 있었다. 향후 연구에서는 타 분야의 국가핵심기반 시설을 대상으로 부가가치 감소율을 파악하고 사례 연구를 통해 도출한 프레임워크를 적용하여 실제 활용 가능성에 대한 검증연구를 수행하고자 한다.

In this study, we tried to suggest a method for calculating the maximum tolerable period of disruption (MTPD) in water supply facilities among national core infrastructure facilities. Currently, the method for estimating the MTPD of national core infrastructure includes the amount of resources available and the recovery time of functions, but there is no specific standard or methodology. By analyzing previous studies and case studies, the framework for determining MTPD using added value among economic factors was confirmed and verified. Based on the framework, it was possible to determine the applicability by deriving estimates in Gongchon. Water Purification Plant in Incheon among domestic water supply facilities. In future research, we intend to conduct verification research on the possibility of actual utilization by identifying the reduction rate of added value targeting national core infrastructure in other fields and applying the framework derived through case study.

For the magnetic field analysis or design, it is important to know the behavior of the magnetic field in an interesting space. Magnetic field mapping becomes a useful tool for the study of magnetic field. In this paper, a numerical way for mapping the magnetic field within the cylindrical center volume of magnet is presented, based on the solution of the Laplace’s equation in the cylindrical coordinate system. The expression of the magnetic field can be obtained by the magnetic flux density, which measured in the mapped volume. According to the form of the expression, the measurement points are arranged with the parallel cylindrical line (PCL) method. As example, the magnetic flux density generated by an electron cyclotron resonance ion source (ECRIS) magnet and a quadrupole magnet were mapped using the PCL method, respectively. The mapping results show the PCL arrangement method is feasible and convenience to map the magnetic field within a cylindrical center volume generated by the general magnet.

As global environmental regulations intensify, the electrification of the mobility industry is accelerating, thereby increasing the demand for high-power electric propulsion systems. Among the various candidates for application, superconducting motors have attracted considerable attention owing to their potential for delivering exceptionally high-power density. In this study, we fabricated two types of GdBa2Cu3O7-δ (GdBCO) superconducting magnets and evaluated their trapped field performance using a 14T superconducting magnetization system. A single grain bulk magnet, grown by the top seeded melt growth (TSMG) method, exhibited a trapped field of 1.93T at 20K. The stacked tapes, fabricated by commercial GdBCO tapes, showed a maximum trapped field of 1.25T at 20K. While the single grain bulk magnet has an advantage in trapped field performance, the stacked tapes offer benefits in terms of simple manufacturing processes and shape flexibility. These results suggest that simultaneous improvement of trapped field performance and motor design optimization could establish superconducting motors as a core technology for nextgeneration electric propulsion systems.

This study aims at the examination of interactive relationships between globalized “local music” and a “global audience,” on the example of Chinese music as to be found on Youtube. Distribution and popularity patterns of Chinese music videos are studied, as well as their public perception. The study is an attempt of pushing forward the boundaries of both ethnomusicology and internet research in the 21st century digital age. Since systematic research approaches to global audiences from an musicological perspective have been undertaken rarely with regard to internet music, this study can be regarded as an methodological suggestion, which might be taken further and adopted into other contexts.

Although field experience learning such as school trips is emphasized at the school site through the 2015 revised curriculum, it often ends with customary events due to problems such as safety issues. Accordingly, this study attempted to explore alternatives to that. A lot of accidents, such as the Sewol ferry accident in 2014, occurred during the field experience study operation. Therefore, by analyzing the “Safe and Educational Operation Manual of Field Experience Learning such as School Trips” of the Sejong City Office of Education, we explored student safety measures that ensure the safety of field experience learning. As a result, in order to ensure the safety of field-experience learning, it is necessary to additionally allocate experts in charge of experiential learning to the (South and North) School Support Center to perform school support work. Also, field experience learning should be operated in a small-scale and tema-type to proceed safely and educationally. Finally, local governments and 17 provincial superintendents' councils should work together to develop and disseminate field experience learning programs.

This study examined the effects of transformational leadership of field commanders on fire rescue workers by dividing leadership characteristics into influence, individual consideration, and motivation. For this purpose, the survey was conducted on 4,600 firefighters across the country. The analysis of the awareness survey showed that individual caring leadership had the most impact on firefighters. Next, it was found that influence leadership and motivation leadership had the following effects. Individual caring leadership is a leadership based on humanism, such as paying attention to individual fire rescue workers and emphasizing how important the organization is to their organization. Individual caring leadership is expected to affect the self-directed structural activity capacity building and safety awareness improvement by confirming how important and important the rescue team itself is and how important it is in the rescue team.
