This paper analyzes the difficulties with the learning of sequence and series of the second-year students who participated in a year long whole class at the university level. The research was carried out at the end of students' third semester. These students were randomly selected. They were applied to one paper and pencil test containing eight task items on sequence and series. In this study, qualitative method (case study design) was used to explore students' difficulties and misunderstandings in learning sequence and series. Students' responses to the questions were divided into three categories: These were "correct", "partial correct" and "false or no responses". Students' responses to the paper and pencil test were evaluated. The results show that students had difficulties and misunderstandings in series and sequence.

Purpose: The purpose of this phenomenological study was to understand the job experiences of the medical aid client managers Method: The data were collected through an in-depth interview from twelve medical aid client managers. It was analyzed using the phenomenological method proposed by Colaizzi (1978). Their feedback was categorized into five items such as 'settlement in the unknown place,' 'exhaustion from work,' 'difficulties in dealing with people,' 'achievement of professionalism and accomplishment,' and 'vision on the new aspect.' Conclusion: Medical aid client managers played diverse roles and they had a role conflict due to unstable position amid feeling proud with new vision on their roles. The results of this study suggested that systematic development of job training programs and description on the duty are needed. Moreover, appropriate legal basis for the duty of medical aid client managers is to be established. Finally, based on this research, more acknowledgement from the Korean nursing society is needed for the new emerging professional job.

This research proposes how to enhance low customer satisfaction with health screening services caused by procedural complexity and limits of health screening. The purpose of this study is to identify sub-components of the service quality provided by general health examination centers. This is a qualitative analysis of in-depth interviews of providers and consumers of medical services. The data were primarily analyzed by affinity diagram, and the data were sorted and analyzed according to the criteria suggested by Donabedian's four components. Four types of quality factors and the health screening service quality components of 39 subordinate items were assessed. Components related to the use of IT facilities comprise a significant amount of the physical factors, and there are high demands for IT facilities among customers.

The purpose of this study was to examine the residential culture of Westerners who reside in Korea. For this study, qualitative case study methods were used. Case study data were collected from 10 households through depth-interviews and observations. Houses were sampled purposively to represent the middle-class American home in Jinhae and Jinju of Korea. This result would be helpful to create useful database for designing and remodeling future desirable housing plan for Westerners in Korea. Furthermore, this would be useful to develop checklist items for Korean immigrant's housing plan who reside in Western country.

In this study, outsourcing behaviors of shoe manufacturing companies were studied and four types of outsourcing were generated based on qualitative data collected through in-depth interviews with 21 practitioners of shoe manufacturing companies. In results, shoe manufacturers are actively adopting outsourcings in production of raw materials(RM) as well as final products(FP). However, relatively less effect is being made on outsourcing in the field of product planning, international marketing and information technology. Four types of outsourcing include shoe manufacturers focusing on: 1) domestic production of RH and FP, 2) domestic production of RM and international production of FP, 3) domestic/international production of RM and FP, and 4) international production of RH and FP. These types were differed. from their manufacturing items, product planning skills and target markets of shoe manufacturing companies.

The hazard assessment in which the potential hazard factors In the buildings are investigated and the scale of the hazard is analyzed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment of all general buildings through the examination of the suitability of assessment model by actual assessment of existing building. Also, the checklist is prepared in itemized questionnaire form for easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.

The purpose of this study is to explore how mathematics educators understand the terms having lexical ambiguity. Five terms with lexical ambiguity, leave, times, high, continuous, and convergent were selected based on literature review and recommendations of college calculus instructors. The participants consisted of four mathematics educators at a large Midwestern university. The qualitative data were collected from open-ended items in the survey. As a result of analysis, I provided participants' sentences with five terms showing their understanding of each term. The data analysis revealed that mathematics educators were not able to separate the meanings of the words such as leave and high when these words are frequently used in daily life, and the meanings in mathematics context are similar with that in daily context. Lexical ambiguity shown by mathematics educators can help mathematics teachers to understand the terms with lexical ambiguity and improve their instructions when those terms should be found in students' conversations.

In this study, a usability evaluation tool was developed for "ICANDUINO", a VR-based mobile application for maker education, and usability evaluation was conducted with a heuristic survey method for experts. The usability evaluation tool was derived through literature review and validated by two experts. It consisted of seven domains (effectiveness, efficiency, satisfaction, learnability, memorability, error, and cognitive load) and twenty-five sub-items. As a result of the usability evaluation conducted for six experts, it received the highest score in the domain of efficiency and the lowest score in the domain of error. The improvements of ICANDUINO were derived by analyzing the qualitative opinions of experts in each of the four stages (training, coding, tinkering, and testing) of making. the results of this study can be used as a guideline when evaluating the usability of a mobile app for education.

The study aimed to qualitatively examine middle school students' engagement in distance instruction during the COVID-19 pandemic. The participants comprised 119 students from a girls' middle school in Seoul, South Korea. To gain an in-depth understanding of the students' experiences, we collected their reflective journals, which included structured items about their learning engagement at three timepoints in 2020: April, July, and December. The following are the results: 10 themes and 18 concepts were derived, and they were integrated into causal conditions (sudden transition due to COVID-19), contextual condition (technology readiness, school education context), central phenomena (high level of behavioral engagement, low emotional engagement), interventional conditions (recognizing the potential of online learning, situational awareness about COVID-19 and online learning), action/interaction phenomena (development and use of self-regulated learning strategies), and consequences (changes in practices and perception towards online learning). Based on the findings, engagement patterns of the participants were classified into five types: proactive, conservative, receptive, reactive, passive learners. The present study demonstrated important findings that are essential for the improvement and development of engaging online learning strategies in the future.
