Background: In Japan, more than 60% of employees are reported to suffer from anxiety and stress. Consequently, Japanese society has begun to address such important issues as psychogenic disability and job-related suicide. Furthermore, given the aging of society and the surge in the number of elderly people requiring care, it is necessary to adequately and proactively support employees who care for their elderly relatives. The purpose of the present study was to investigate caregiver burden in caring for elderly relatives and work-related stress factors associated with mental health among employees. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine mental health status. Results: The proportion of participants with a high K10 score was 15% (n = 106). Having little conversation with their supervisor and/or coworkers significantly increased the risk of depression [odds ratio (OR) 1.8], as did high job overload (OR 2.7) and job dissatisfaction (OR 3.8), compared with employees who frequently conversed with their supervisor and/or coworkers. Caring for elderly relatives as a prominent characteristic of an employee was a significant risk factor for depression (OR 2.1). Conclusion: The present study demonstrated that employees who were caring for elderly relatives were significantly associated with an increased risk of depression. To prevent depressive disorders, it may be important to focus on reducing the work-caregiving role conflict, as well as enhancing employees' job control and better rewarding their efforts in the workplace.

This study was performed to explore the family support. the quality of marital relationship, and health promoting behaviors of the mature gravidas. and to validate the relationship between them. From November, 1999 to June. 2000. mature gravidas older than 35(N=82) were recruited from K University Hospital located in Seoul and Kyungki Province. Korea. Data was collected using a self-rating method and semi-structured interview. The questionnaires were: Perceived Social Support from Family developed by Procidano & Heller (1983). Quality of Marital Index by Norton (1983). and Health Promoting Life-style Profile by Walker, Sechrist, & Pender (1987), Interviews were conducted using the interview guide with open-ended questions related to health concerns and health promoting behaviors. Data was analyzed using a pc-SAS program for quantitative data. The levels of the perceived family support and the quality of marital relationship were relatively high. The relationship between perceived family support and quality of marital relationship, and health promoting life-style behaviors was statistically significant. Six themes emerged as primary concerns for the mature gravidas during childbearing: 'Concerns related to the fetal wellbeing', 'Concerns related to fetal education', 'Concerns related to the maternal physical health', 'Concerns related to the maternal emotional health', 'Concerns related to safe delivery' and 'Concerns related to child-rearing'. Nursing implications for practice include expanding prenatal assessment inventories to address the concerns and support system of mature gravidas.

An important factor in education is ensuring reliable quality of education. There are a variety of ways based on criteria to ensure the quality of education. To ensure quality management, attendance is important which is highly reliable rating at the account education of Ministry of Employment and Labor and sevice training of Health Care. In contrast, the service training of health care professionals was consisting of formal attendance management, quality of education has been raised as a problem. Recently developed USN-based attendance management system is effective. But if education is proceed at a large number of small scale in the area of education, cost, portability, systeme management, the reliability of the Trainee's attendance remained as problems to solve. To address these needs, this paper quoted low-cost attendance management system which was desighned and implemented by barcode and PC camera. As a result the actual maintenance training system showed a 98% satisfaction in terms of administrator and 95% satisfaction in terms of Trainee.

Purpose: This scoping review aimed to synthesize the characteristics and effects of interventions designed to prevent unintentional home injuries in older adults in Korea. Methods: The review was conducted following the Joanna Briggs Institute protocol. A literature search was performed for studies published between 2001 and 2022 in the DBPia, RISS, KMBase, and NDSL databases. A total of 1,620 studies were identified, and 27 studies were included in the final analysis. Data were analyzed for characteristics of the literature, intervention-related unintentional injury mechanisms, and safety areas. Results: Most selected studies utilized a quasi-experimental design and targeted elderly women. In terms of injury mechanisms, 21 of 27 studies focused on falls, 2 on fire/disaster, 3 on drugs, and 1 on food. The most common preventive intervention for falls was exercise, and its effectiveness was verified using physical safety variables. Interventions in the fire/disaster, drug, and food domains were all educational, and changes in knowledge, behavior, and attitude were verified. Conclusion: This study confirmed the effectiveness of interventions for preventing unintentional injuries in the homes of community-dwelling older adults. These findings can serve as a foundation for developing and implementing unintentional injury prevention interventions at home for community-dwelling older adults. Multidisciplinary research is needed to address multifaceted safety issues by considering the home environment and injury risk factors.

In the design of a rotor shaft, care should be taken to minimize vibration by taking into account the sources of vibration. In addition, the intensity critical speed, stability, and other related aspects of the system must be considered. especially when it is operated at a critical speed, it is important to address issues related to vibration, as an increase in the whirling response of the rotor shaft can cause damage to the shaft, destruction of the rotor parts, and detrimental abrasions on the bearings. In this thesis, the vibration characteristics of a rotor shaft are investigated through the use of the finite element method. Variations of the diameters and lengths were used to determine the effect of a rotor shaft using Beam No.188(3D linear strain beam) in ANSYS version 11.0 as a universal interpretation program for finite elements. Special care was taken to prevent excessive vibration, which can result from resonance at the initial stage, in the formulation of a dynamic design for a rotor shaft through calculations while changing the diameters and the lengths of the shaft. Moreover, the dynamic characteristics of the critical speed, total mass, D/L(diameter to length) ratio, and natural frequency were verified. Furthermore, the rotor shaft applied by bearing element was calculated and compared by using Combi No. 214(2-D spring-damper bearing).

Unmet healthcare is an important indicator to measure accessibility of healthcare services. To examine the latest status of unmet healthcare needs in South Korea, four different data which is composed of nationally representative sample of South Korean population were used; the Korea National Health and Nutrition Examination Survey (KNHANES, 2007-2020), the Community Health Survey (CHS, 2008-2020), the Korea Health Panel Survey (KHP, 2011-2018), and the Korean Welfare Panel Study (KOWEPS, 2006-2020). The proportion of individuals reporting unmet healthcare needs were 6.4% (KNHANES), 5.4% (CHS), and 12.2% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.9%, -9.1%, and -5.5%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.0% (KNHANES), 0.4% (CHS), 2.2% (KHP), and 0.4% (KOWEPS). The APC was -11.3%, -17.0%, -12.2%, and -21.2%, respectively. Overall, the low-income and the elderly population reported a higher rate of unmet health care needs. Although the overall experience rate of unmet medical care due to cost decreased over the past decade, the disparity between the lowest and highest income groups still remained in 2020. Disparity between income levels and age groups is a challenge to address in healthcare system, and these results suggest the need for adequate health coverage for the low-income and the elderly populations.

Objective: The purpose of this study was to analyze the experiences of foreign students in childcare practicum, with a specific focus on identifying the difficulties they encountered and the values they derived from their practicum experiences. The aim was to gain insights that can contribute to improving practicum support for these students. Methods: A total of 6 foreign students were selected as participants for this study using snowball sampling. The data collection period spanned from May 2021 to March 2023, during which semi-structured interviews were conducted and qualitatively analyzed. Results: Foreign students faced challenges in securing practicum placements prior to the start of their program. Communication difficulties necessitated the use of interpreters to interact with children. Additionally, documenting information in a language other than their mother tongue posed a challenge. Consequently, there was a need for tailored training support to address the specific needs of foreign students in childcare practicum. Despite these challenges, the students reported rewarding and valuable experiences during their practicum. These experiences included discovering the teaching identity in Korea, learning about desirable practices in the field, recognizing and addressing personal shortcomings, and developing a sense of vocation for the advancement of infant education in their home countries. Conclusion/Implications: If we actively listen to and provide appropriate support for the specific needs of foreign students in their childcare practicum, they have the potential to become excellent childcare teachers who can foster a harmonious and inclusive environment within our multicultural society.

In the Proxy Mobile IPv6 (PMIPv6), the data transmission performance may be degraded when the two communicating hosts are located within the same mobile domain, since all the data packet shall be delivered by way of Local Mobility Anchor (LMA). In this paper we propose an extensional scheme of PMIPv6 using binding query. In the proposed Query-based PMIPv6 (Q-PMIPv6) scheme, the Mobile Access Gateway (NAG) of Correspondent Node (CN) sends a binding query to LMA to obtain the Proxy Care-of-Address of Mobile Node (MN). Since then, CN and MN can communicate with each other by using an optimized data path. For comparison, we performed the numerical analysis and the ns-2 simulations for the proposed Q-PMIPv6 scheme and the existing PMIPv6 and PMIPv6 Localized Routing (PMIPv6-LR). From the results, we can see that the proposed scheme outperforms the existing PMIPv6 and PMIPv6-LR schemes in terms of the signaling control and data delivery costs.

Context: Genuine community participation does not denote taking part in an action planned by health care professionals in a medical or top-down approach. Further, community participation and health education on breast cancer prevention are not similar to other activities incorporated in primary health care services in Iran. Objective: To propose a model that provides a methodological tool to increase women's participation in the decision making process towards breast cancer prevention. To address this, an evaluation framework was developed that includes a typology of community participation approaches (models) in health, as well as five levels of participation in health programs proposed by Rifkin (1985&1991). Method: This model explains the community participation approaches in breast cancer prevention in Iran. In a 'medical approach', participation occurs in the form of women's adherence to mammography recommendations. As a 'health services approach', women get the benefits of a health project or participate in the available program activities related to breast cancer prevention. The model provides the five levels of participation in health programs along with the 'health services approach' and explains how to implement those levels for women's participation in available breast cancer prevention programs at the local level. Conclusion: It is hoped that a focus on the 'medical approach' (top-down) and the 'health services approach' (top-down) will bring sustainable changes in breast cancer prevention and will consequently produce the 'community development approach' (bottom-up). This could be achieved using a comprehensive approach to breast cancer prevention by combining the individual and community strategies in designing an intervention program for breast cancer prevention.

Purpose: Administering early parenteral amino acids to very low birth weight (VLBW) premature infants (birth body weight [BBW]<1,500 g) is challenging due to factors such as holidays, cost, and access to sterile compounding facilities. Using advance-prepared parenteral nutrition (PN) may address this issue and should be evaluated for its safety and potential benefits. Methods: We extracted data from medical records collected between July 2015 and August 2019. VLBW infants received PN for at least seven days and were split into two groups: the traditional group (n=30), which initially received a glucose solution and then PN on workdays, and the pre-preparation group (n=16), which received advance-prepared PN immediately upon admission to the neonatal intensive care unit. Results: The median BBWs of the traditional and pre-preparation groups were 1,180.0 vs. 1,210.0 g. In the initial two days, the pre-preparation group had a significantly higher amino acid intake (2.23 and 2.24 g/kg/d) than the traditional group (0 and 1.78 g/kg/d). The pre-preparation group exhibited greater head circumference growth ratio relative to birth (7th day: 1.21% vs. -3.57%, p=0.014; 21st day: 7.71% vs. 3.31%, p=0.017). No significant differences in metabolic tolerance were observed. Conclusion: Advanced preparation of PN can be safely implemented in VLBW preterm infants, offering advantages such as early, higher amino acid intake and improved head circumference growth within the first 21 days post-birth. This strategy may serve as a viable alternative in settings where immediate provision of sterile compounding facilities is challenging.
