This paper presents a significant contribution to aided design by conducting an analytical examination of geometric links with the aim of establishing criteria for assessing an analogy measure of the extrinsic geometric and kinematic characteristics of the Variable Compression Ratio (VCR) engine with a Geared Mechanism (GBCM) in comparison to the existing Fixed Compression Ratio (FCR) engine with a Standard-Reciprocating Crankshaft configuration. Employing a mechanical approach grounded in projective computational methods, a parametric study has been conducted to analyze the kinematic behavior and geometric transformations of the moving links. The findings indicate that in order to ensure equivalent extrinsic behavior and maintain consistent input-output performance between both engine types, precise adjustments of intrinsic geometric parameters are necessary. Specifically, for a VCR configuration compared to an FCR configuration, regardless of compression ratio and gearwheel radius, for the same crankshaft ratios and stroke lengths, it is imperative to halve lengths of connecting rods, and crank radius. These insights underscore the importance of meticulous parameter adjustment in achieving comparable performance across different engine configurations, offering valuable implications for design optimization.

Purpose: This study was to describe and develop public health nursing. Methods: Data were collected from 19 nurses sampled from 5 public health centers. The grounded theory of Strauss and Corbin (1990) was applied. Results: As a result, 48 concepts, 23 subcategories, and 11 categories were deduced from open coding. In axial coding, casual conditions 'facing difficulties of practical administration' and 'attaching importance to health support for residents' and context condition 'assessing of residents' service needs' impacted phenomenon 'searching for efficient performing methods.' Intervening conditions 'forming of support system' and 'working with positive,' and action-interaction conditions 'improving of resident's health and medical accessibility' and 'striving for self-development' lead to consequences 'carried out promptly for field-based problem solving,' 'mastered of successful program planning methods' and 'solving the issues with existing style.' The periods of process were divided into 4 stages, confirming program-contents, probing program-method, developing program-strategies, and applying program-competencies. The core category, ‘strengthening of practical-planning work competencies' incorporated the relationship between and among all categories and explained the process. Conclusion: This study described public health nurses' performance in Korea. These findings have important implications for the practice and must be considered to develop competencies for planning and practice of public health.

Purpose This study is to phenomenologically discover key antecedents and outcomes of behavioral process of SNS users who have multiple SNS sub-accounts. Unlike previous studies that focused on user behavior in the context of a specific SNS platform, this study attempts to describe how and why individual manages their multiple sub-accounts across a variety of SNS platforms. Design/methodology/approach By applying the grounded theory methodology (GTM) to elucidate the unique behavior in SNS platforms, this study has conducted in-depth interview with 14 respondents who handle multiple accounts across the SNS platforms. As a results of analyzing the interview manuscripts, this study has extracted 47 concepts, 10 sub-categories and 6 main categories by conducting open coding, axis coding, and selective coding. Findings By analyzing interview data, this study has derived main categories such as account management, impression management, self-categorization, authority to determine the relationship, digital shadow work, and portfolio SNS accounts from qualitative interview data. This study has also conducted a process analysis that represents how main categories could be inter-related. Based on findings, this study provides a new phenomenological perspective to understand the behavioral process of SNS users' sub-account usage experience.

Purpose: South Korea has expanded its accelerated second-degree Bachelor of Science in Nursing program to resolve its supply-demand imbalance in nursing, although how these students are adapting to and performing in college after admission remains unclear. Therefore, this study aimed to conduct an in-depth exploration of how Korean accelerated second-degree Bachelor of Science nursing students interact with society and adapt to college life for establishing further supportive educational policies and programs. Methods: Participants comprised 20 South Korean accelerated second-degree Bachelor of Science in Nursing students. The data were collected via online or offline in-depth interviews and analyzed using Strauss and Corbin's grounded theory and by applying a constant comparative method to achieve theoretical saturation. Results: The core category, derived using open, axial, and selective coding, was "process of the uncharted journey toward a new dream." The participants' college adaptation processes were found to involve three phases: trial and error, adjustment, and acceptance and integration. Conclusion: These findings can be used to develop, apply, test, and improve various support programs for accelerated second-degree Bachelor of Science in Nursing students and to advance the nursing profession by nurturing a workforce with diverse academic backgrounds and faster college life adaptation.

Social capital is an important resource for Korean immigrant children's successful school life in the U.S. because most immigrants are not familiar to new language and culture. However, immigrant parents and their children have limited ability to join and create social networks freely both inside and outside school. We, the researchers of this study, adopted qualitative research method: open-ended in-depth interview, coding and analysis based on grounded theory. The result of this study reveals that Korean immigrant parents utilize their coethnic networks in getting educational information and English plays important role in educational decision-making process of the parents.

Purpose: The purpose of the study was to explore and describe the experience of Korean college students on suicide attempts. Methods: Eight students participated and data were collected through in-depth individual interviews between September, 2011 and April, 2012. Data were analyzed using Strauss and Corbin's grounded theory method. Results: Analysis showed that the central phenomenon of suicide attempt experience of college students was 'inextricable despair'. Causal conditions were 'sense of shame by failure to achieve perfect independence' and 'a big gap between reality and ideals'. Contextual conditions were 'extreme situation of being cornered' and 'excessive changes in emotions'. Intervening conditions were 'important others' and 'perspectives on the world'. Action/interaction strategies were 'temporary efforts' and 'gathering up one's mind'. Consequences were 'trauma as one's own hurt', 'conflict between life and death' and 'becoming mature'. Conclusion: The results of this study provide an in-depth understanding of the experience of college students with attempted suicide. It is necessary to develop programs to prevent suicide attempts by college students and these results can be used as a basis for program development.

It is more important than ever to have talent with innovative capacities for sustainable agriculture and rural areas, but adolescents's interest in and understanding of agriculture and rural areas is very low. Therefore, this study analyzed the experiences of participants in the Agriculture Career Exploration Activities Program. and suggests strategies to improve and revitalize agricultural education based on these findings. First, Institutions and facilities that run agricultural education programs need opportunities for self-checks. Second, it is necessary to develop various contents and its distribution channels to enable the experience related to it in daily life. Third, it is important to provide experience in the middle school curriculum, which requires the use of a system such as the Free Semester System. Fourth, education and promotion to parents and teachers is also important, as it has a direct impact on youth's perception of it.

Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.
