While the quality of machine translation is getting better and better, it is still not perfect. In this case, how the user treats the imperfect machine translation results determines whether the user achieves the purpose for using machine translation. In this process, user evaluations are a key factor. User evaluations are not objective nor accurate. User evaluations are a subjective evaluation of the user and is related to the user. Therefore, this paper attempts to analyze the relationship between the level of the user's L2 and user evaluations. This paper surveyed 69 Chinese users to understand the current status of their use of machine translation, including frequency of use, purpose of use, favorite machine translation, reasons for preferences, and satisfaction with the quality of the machine translation used. At the same time, for specific translation articles, it lets users evaluate the accuracy and fluency of machine translation articles. The survey results show that users with low L2 levels used machine translation at a higher frequency and were more inclined to evaluate machine translation from the perspective of ease of use. In addition, statistical analysis of the evaluation results found that users’ evaluation of machine translation was related to the user's own level L2. The lower the L2 level, the higher the evaluation of the adequacy and fluency of machine translation, and the higher the assessment of the overall quality of the machine translation.

Many studies have found that regardless of who the evaluator is― interpreter or the service user―content-related criteria are deemed the most important in assessing interpreting quality. However, it must be noted that service users, in most cases, do not understand the source language. Naturally, this means that service users are in a disadvantageous position to evaluate the content-related quality of interpreting as they cannot compare the contents of the target text against the source text. The purpose of this study is to investigate how the service user evaluates the content-related quality of interpreting without having access to the source text. Through the use of structural equation modeling, this study shows that service users depend on the form-related criteria and not on the delivery-related criteria to guess how well the original message was delivered content-wise. Furthermore, it is found that when the interpreter fails to maintain a constant rate of speech, the service users regard it as a sign of drop in sense consistency.

One of the authors of this study has engaged in the research of ‘Multilingual Word Translation Service based on Word Semantic Analysis’ for multicultural families since 2016. The research aimed to develop a web- and an application-based multilingual translation service which provides advanced Korean vocabulary used in school newsletters for married female immigrants. For the research, the data, consisting of word pairs, of the Multilingual Learners' Dictionary was provided by the National Institute of Korean Language. However, the Korean-Chinese pairs have not been completed yet. So, with the data for the Korean-Chinese translation dictionary transferred from the ETRI, the Korean-Chinese word translation web service started as a pilot operation. In this regard, this study presents the details of the multilingual translation web service, including the purpose, main users, and design principles. In addition, the study compares ETRI Korean-Chinese Translation Dictionary with Multilingual Learners' Dictionary in terms of structure, translation strategy, and process, and proposed ways to improve the web service.

While considerable research suggests that users' uncertainty gradually decreases, as they proceed through the information seeking process, others argue that it can arise at any stage of their information seeking process. Reflecting the latter view, this study examined user perceptions of uncertainty in the final stage of users' information seeking process, the stage of search results evaluation. Considering the significance of Web search engines for academic study, this study investigated the relevance decision stage of scholarly researchers in the field of science, who use Web search engines for their academic study. Based on the analysis of the users' uncertainty, this study provided implications to improve information systems and Web contents design.

The purpose of this study is to suggest an appropriate index for evaluating preferences of Web contents by examining the h-index and its variants. It focuses on how successfully each index represents relative user preference towards topical subjects. Based on data obtained from a popular IT blog (engadget.com), subject values of the h-index and its variants were calculated using 53 subject categories, article counts and the 'Likes' counts aggregated in each category. These values were compared through critical analysis of the indices and Spearman rank correlation analysis. A PFNet (Pathfinder Network) of subjects weighted by $h_T$ values was drawn and cluster analysis was conducted. Based on the four criteria suggested for the evaluation of Web contents, we concluded that the $h_T$-index is a relatively appropriate tool for the Web contents preference evaluation. The $h_T$-index was applied to visually represent the relative weight (topic preference by user 'Likes' count) for each subject category of the real online contents after suggesting the relative appropriateness of the $h_T$-index. Applying scientometric indicators to Web information could provide new insights into, and potential methods for, Web contents evaluation. In addition, information on the focus of users' attention would help online informants to plan more effective content strategies. The study tries to expand the application area of the h-type indices to non-academic online environments. The research procedure enables examination of the appropriateness of the index and highlights considerations for applying the indicators to Web contents.

To enhance the utilization of the traffic channels of a network (instead of allocating radio channel to an individual user), a channel or a group of channels are allocated to a user group. The idea behind this is the statistical distribution of traffic arrival rates and the service time for an individual user or a group of users. In this paper, we derive the blocking probability and throughput of a subscriber station of Worldwide Interoperability for Microwave Access (WiMAX) by considering both the connection level and packet-level traffic under a complete partition scheme. The main contribution of the paper is to incorporate the traffic shaping scheme onto the incoming turbulent traffic. Hence, we have also analyzed the impact of the drain rate of the buffer on the blocking probability and throughput.

Objective : This study aimed to investigate the item-level psychometric properties of the K-USER-P for people diagnosed with neurological disorders using Rasch analysis. Methods : The participants were 165 individuals diagnosed with neurological disorders including stroke, Spinal Cord Injury (SCI), and Traumatic Brain Injury (TBI). Rasch analyses were conducted to examine the descriptive statistics, unidimensionality, item difficulty, fit statistics, differential item functioning, precision, and ceiling and floor effects. Results : The items of the K-USER-P show good item-total correlation (r=0.40-0.81) and high factor loadings (λ=0.374-0.876), with the exception of some items in the frequency construct. Regarding the order of difficulty of evaluation items, the most difficult item was ‘work/education’ (1.10 logits) in the restrictions, and the easiest item was ‘telephone/computer’ in the restrictions (-1.23 logits). In addition, the majority of test items demonstrated a good fit to the Rasch models. The restrictions and satisfaction construct demonstrated more good precision than the frequency construct. Conclusion : The items of the restrictions and satisfaction construct in the K-USER-P showed good psychometric properties for participation assessment of individuals with neurological disorders such as stroke, SCI and TBI in South Korea.

본 연구는 재난관리자원 통합관리시스템(KRMS)의 낮은 활용률을 설명하기 위해 사용자 및 전문가 기반 평가를 활용한 사용성 분석을 수행하였다. 전문가 휴리스틱 평가는 시스템의 효과성·효율성·만족 도·인터페이스·기타 요소를 중심으로 검토되었다. 그 결과 전체 평가 항목 중 ‘충족’ 항목은 없었고, ‘부분 충족’과 ‘미충족’이 대부분을 차지하였으며, 심각도 또한, 2점(보통 수준 문제)이 가장 높은 비중을 보였다. 한편 사용자 평가는 서울시 지방공기업 재난관리 담당자를 대상으로 대표 과업 기반의 시나리오 수행 후 SUS 설문을 실시하였다. SUS 점수는 평균 24.6점으로 나타나 국제적 기준에서 ‘Not Acceptable’ 수준에 해당하였으며, 복잡한 절차, 메뉴 구조의 과분절 및 낮은 직관성 등이 주요 어려움으로 확인되었 다. 종합하면 KRMS는 정보 구조와 절차 흐름의 복잡성이 높아 실제 업무 맥락에서 사용성이 제약되는 것으로 분석되었다. 본 연구는 공공 재난관리 시스템의 사용자 경험을 체계적으로 진단한 최초의 실증적 사례로서, 향후 KRMS의 개선 방향과 정책적 시사점을 제시하는 데 기초 자료를 제공한다.

This study analyzed the usability of the Korea Disaster Management Resource Integrated Management System (KRMS) using combined user- and expert-based evaluations to explain its low utilization in practice. Expert heuristic evaluation assessed effectiveness, efficiency, satisfaction, interface quality, and related factors, and found that none of the items were rated as “met,” with most judged “partially met” or “not met.” Severity ratings indicated that level 2 (moderate problems) accounted for the largest proportion. User evaluation was conducted with disaster management practitioners from a local public enterprise in Seoul, who completed representative task scenarios and the System Usability Scale (SUS). The average SUS score was 24.6, placing KRMS in the “Not Acceptable” range in international benchmarks. Key difficulties included complex procedures, overly segmented menu structures, and low intuitiveness, suggesting that structural and procedural complexity constrains usability in real work contexts and informing future system improvement and policy considerations.

패션은 개인 취향이 구매의 첫 번째 기준으로 작용하는 분야인 만큼 개인화된 추천 서비스가 일찍이 자리를 잡았다. 특히 모바일 패션 커머스에서 구매전환을 높이는 중요한 전략으로 꼽히며 더욱 정교화 되고있다. 이로 인해 개인화 추천서비스의 사용자 경험 관해 많은 연구들이 이루어졌지만, 세부적인 소비자의 구매여정에 따라 확인한 연구는 부족한 실정이다. 본 연구는 개인화 추천서비스의 사용자 평가가 구매여정별로 차이가 있는지 살펴보고, 구매의도와 만족도에는 어떠한 영향을 미치는지 밝 히고자 하였다. 분석결과 다양성, 신뢰성, 편의성은 0.001%수준, 유용성은 0.05% 수준에서 구매여정 단계별로 유의한 차이를 보였다. 또한 만족도는 인지 및 흥미단계에서 새로움과 유용성이, 검색단계에서 신뢰성과 다양성이 높게 나타나는 등 각 단계별로 차이를 보였으며, 구매의도는 구매 후 단계를 제외하고 유용성과 신뢰성이 높은 결과를 보였다. 본 연구는 소비자의 개인화 추천 서비스에 대한 사용자 평가에 차이가 있음을 밝힘으로써 구매 여정에 따른 개인화 추천서비스 사용자 평가의 영향에 대한 이해를 높였다는 점에서 이론적 의의가 있으며, 모바일 패션커머스의 개인화 추천서비스 전략개선의 방향성을 제시했다는 실무적 의의 를 지닌다. 추후 개선안의 효과성에 대한 연구가 진행된다면 더욱 고도화된 개인화 추천서비스 전략에 기여할 수 있을 것이다.

Fashion is a field in which personal taste acts as the first criterion for purchase, and it is being refined as an important strategy to increase purchase conversion on mobile. Although related studies have been conducted, there are insufficient studies to confirm this according to the detailed purchasing journey of consumers. The purpose of this study is to examine whether the evaluation of user experience factors of personalized recommendation service differs by purchase journey, and to reveal whether it affects purchase intention and satisfaction. Variety, reliability, and convenience showed a significant difference at the level of 0.001% and usefulness at the level of 0.05%. Satisfaction levels were different for each stage, such as novelty and usefulness in the cognitive and interest stage, and high reliability and diversity in the search stage. It has theoretical significance in that it enhances the understanding of the purchase journey by revealing that there is a difference in user evaluation of the personalized recommendation service, and it has practical significance in that it suggests the direction of improvement of the personalized recommendation service strategy. If research on effectiveness is conducted in the future, it will be able to contribute to an advanced strategy.
