Although scholars have been using qualitative research commonly since 1990 in Korea, discussions on the criteria for the quality of qualitative research have been rare. The purpose of this paper was to analyze the trends of qualitative research methodology in Family Studies, and critically examine qualitative research articles published in the three most prominent journals in the field of family studies. The three journals were Journal of Korean Home Management Association, Journal of the Korean Home Economics Association, and Journal of Family Relations. During the period from 1998 to 2003, twenty seven published articles were identified as qualitative research articles from the three journals. Qualitative research in family studies had a wide variety of purposes, but the articles shared similar characteristics: the main goal was to understand the nature of the research participants' experiences and perspectives. The common data collection techniques were in-depth interview, journal writing, and document analysis. Also, all research articles had applied various techniques to data analysis such as grounded theory, or van Manen's method. This article also discussed the usefulness of qualitative research methodology in broadening and deepening the knowledge body in Korean Family Studies.

Missile operating at supersonic conditions experiences considerable high temperature environments that is caused by aerodynamic heating as a result of the temperature gradient through boundary layer that surrounds it. This is one of important problems to the designer due to temperature limitation of structural materials. Because prediction of aerodynamic heating on missile needs unsteady calculation according to a flight trajectory, approximate method approach is efficient at design stage. In this paper, improved aerodynamic heating analysis scheme is introduced, which calculates heat flow and temperature by simple pressure field prediction on a missile body and fin. The prediction results are compared with measured data and MINIVER codes results.

The study used 24 clothing salespersons who had turnover experiences. It used a qualitative research method, through which the following turnover motives were found. The turnover motives can be classified into two: voluntary and non-voluntary. The voluntary turnover motives include marriage, career change, wages, human relationship, family moving, study abroad, health problems, and so forth. This study finds that some salespersons made a turnover because they did not like the products and brand or they preferred another products and brand. This kind of turnover is unique in the field of clothing sales and seldom found in the motives of salesperson turnover in other fields. The non-voluntary turnover motives are caused by non-personal, circumstantial factors which include the bankruptcy of companies due to economic depression, withdrawal of salesroom from department stores due to low sales, etc. This means that the creation, rise, and fall of fashion brands are closely related to frequent turnover of clothing sale associates. As there are various motives for the salesperson turnover, so it is necessary for the clothing industry to examine and investigate the trends of its salespersons and establish an appropriate policy to cope with the matter.

Everyone wishes to live a happy life. Unfortunately, however, most people who have grown up in dysfunctional families grow up living wounded inner child' .This wounded inner child not only experiences conflicts in interpersonal relations but also exchanges wounds with others, which inflicts pain on them. Besides, they suffer from dependence and addiction, leading them to have miserable lives. This study seeks to review the definitions of the inner child and treatment methods using movies for the wounded inner child. The study found that as a field of art therapy, cinema therapy can have a positive effect on curing the emotionally wounded inner child.

Site or multi-unit (MU) risk assessment has been a major issue in the field of nuclear safety study since the Fukushima accident in 2011. There have been few methods or experiences for MU risk assessment because the Fukushima accident was the first real MU accident and before the accident, there was little expectation of the possibility that an MU accident will occur. In addition to the lack of experience of MU risk assessment, since an MU nuclear power plant site is usually very complex to analyze as a whole, it was considered that a systematic method such as probabilistic safety assessment (PSA) is difficult to apply to MU risk assessment. This paper proposes a new MU risk assessment methodology by using the conventional PSA methodology which is widely used in nuclear power plant risk assessment. The logical failure structure of a site with multiple units is suggested from the definition of site risk, and a decomposition method is applied to identify specific MU failure scenarios.

Normal Operation Safety Survey (NOSS) is a safety management tool used by air traffic control organizations to measure data related to threats and errors to proactively prevent accidents before they occur. NOSS was developed to be applied to the air traffic control field according to the concept of Line Operation Safety Audit (LOSA) conducted by airlines to reduce human errors in the cockpits. Safety management based on data is crucial for the prevention of control-related accidents, and the competency of observers for this is important for the successful implementation of NOSS. Based on LOSA implementation experiences and expert interviews, this paper introduces the international NOSS methods and discusses the key factors required for effective observation and the implementation methods and implications of NOSS observer training.

In order to improve and promote immersive learning experiences for English as a Second Language (ESL) students, the deployment of a YOLOv5 model for object identification in videos is proposed. The procedure includes collecting annotated datasets, preparing the data, and then fine-tuning a model using the YOLOv5 framework. The study's major objective is to integrate a well-trained model into ESL instruction in order to analyze the effectiveness of AI application in the field.

Wearable metaverse devices have sparked enthusiasm as innovative virtual computing user interfaces by addressing a major source of user discomfort, namely, motion-to-photon latency. This kind of latency occurs between the user motion and screen update. To enhance the realism and immersion of experiences using metaverse devices, the vergence-accommodation conflict in stereoscopic image representation must be resolved. Ongoing research aims to address current challenges by adopting vari-focal, multifocal, and light field display technologies for stereoscopic imaging. We explore current trends in research with emphasis on multifocal stereoscopic imaging. Successful metaverse visualization services require the integration of stereoscopic image rendering modules and content encoding/decoding technologies tailored to these services. Additionally, real-time video processing is essential for these modules to correctly and timely process such content and implement metaverse visualization services.

The research is centered on veteran educators in the field of early childhood education who possess more than 20 years of teaching experience and have been recognized with awards for their outstanding achievements. The selection of participants was based on specific criteria, such as the number of years of experience and recognition received from the Ministry of Education's Teaching Innovation Competition in Korea. Eight teachers who met the specified criteria were selected to participate in the study. A qualitative phenomenological research study was carried out using semi-structured interviews to gain insight into the experiences and perspectives of the participants. The study identified five main themes: cultivating interpersonal relationships, establishing interactive classroom settings, providing impactful educational methodologies, facilitating healthy habits and character education, and creating a supportive environment for teachers' well-being. The study seeks to improve comprehension of teaching methodologies and offer suggestions for professional development, teacher training, and educational policies.
