Lysosomes are organelles surrounded by membranes that contain acid hydrolases; they degrade proteins, macromolecules, and lipids. According to nutrient conditions, lysosomes act as signaling hubs that regulate intracellular signaling pathways and are involved in the homeostasis of cells. Therefore, the lysosomal dysfunction occurs in various diseases, such as lysosomal storage disease, neurodegenerative diseases, and cancers. Multiple forms of stress can increase lysosomal membrane permeabilization (LMP), resulting in the induction of lysosome-mediated cell death through the release of lysosomal enzymes, including cathepsin, into the cytosol. Here we review the molecular mechanisms of LMP-mediated cell death and the enhancement of sensitivity to anticancer drugs. Induction of partial LMP increases apoptosis by releasing some cathepsins, whereas massive LMP and rupture induce non-apoptotic cell death through release of many cathepsins and generation of ROS and iron. Cancer cells have many drug-accumulating lysosomes that are more resistant to lysosome-sequestered drugs, suggesting a model of drug-induced lysosome-mediated chemoresistance. Lysosomal sequestration of hydrophobic weak base anticancer drugs can have a significant impact on their subcellular distribution. Lysosome membrane damage by LMP can overcome resistance to anticancer drugs by freeing captured hydrophobic weak base drugs from lysosomes. Therefore, LMP inducers or lysosomotropic agents can regulate lysosomal integrity and are novel strategies for cancer therapy.

The wave-propagation phenomenon in an infinite medium has been used to describe the physics in many fields of engineering and natural science. Analytical or numerical methods have been developed to obtain solutions to problems related to the wave-propagation phenomenon. Energy radiation into infinite regions must be accurately considered for accurate solutions to these problems; hence, various numerical and mechanical models as well as boundary conditions have been developed. This paper proposes a new boundary condition that can be applied to scalar-wave or horizontally-polarized shear-wave (or SH-wave) propagation problems in layered waveguides. A governing equation is obtained for the SH waves by applying finite-element discretization in the vertical direction of the waveguide and subsequently modified to derive the boundary condition for the infinite region of the waveguide. Using the orthogonality of the eigenmodes for the SH waves in a layered waveguide, the new boundary condition is shown to be equivalent to the existing root-finding absorbing boundary condition; further, the accuracy is shown to increase with the degree of the new boundary condition, and its stability can be proven. The accuracy and stability are then demonstrated by applying the proposed boundary condition to wave-propagation problems in layered waveguides.

The purpose of this study was to investigate music therapists' awareness of the music therapy national certification (MTNC). Online questionnaires were distributed to music therapists who voluntarily agreed to participate in this research and 143 completed surveys were collected for analysis. The questionnaire consisted of 37 questions (background information, awareness of the necessity for MTNC, expected effects of national certification, and qualification management). According to the collected data, music therapists reported that they were highly aware of the necessity for MTNC. The participants believed that excessive issueing of private licenses might deteriorate the quality of music therapy services and job opportunities. As alternatives to address private license-related issues, participants agreed with the establishment of national certification system. Given that participants did not have enough knowledge of MTNC and the MTNC may have both pros and cons, the results should be generalized with caution. Still, this study could provide basic information for further discussion on the establishment of MTNC.

This study aims to prevent maternal social isolation by analyzing the causes of postpartum obesity and postpartum depression and stress in Korea. Gneral characteristics of mothers as a result of the study: 91.1% (102 people) answered that they had social experience, and only 8% (9 people) answered that they had no social experience. In the question of whether to return to society, 17.9% responded that they have already returned, 54.5% did not, and 18.8% were on maternity leave. As a result of examining the level of BMI increase among mothers through chi-square test of BMI changes before and after childbirth and general characteristics, 55% experienced below-average BMI increase; 45% experienced above-average BMI increase. Those in their 30s accounted for 40.2%, and those in their 40s accounted for 57.1%. Postpartum obesity and maternal psychological status (t-test): Mothers with postpartum obesity were more hypersensitive (t = -1.997, p = 0.048) and more prone to suffer from hard breathing (t = -1.930, p = 0.056), emptiness (t = -2.673, p = 0.010), and body numbness (t = -2.315, p = 0.024) than mothers who are not suffering from not postpartum obesity. Per the results of postpartum BMI increase and maternal psychological state (t-test) analysis, mothers with an average increase in postpartum BMI were more depressed than mothers who did not. Research Results - Postpartum obesity due to pregnancy and childbirth has been identified as an important individual cause affecting mental and physical problems after childbirth. In conclusion, I also think that the government should support the management of maternal obesity and the elimination of depression through the results of this study.

This study was undertaken to examine the effects of social support, as well as avoidance coping, depression and suicidal ideation, of the elderly over 65 years, in G city. This was a descriptive survey study, enrolling 482 subjects from 9 elderly schools in G city, from October 31, 2019 to 1. Data collected were analyzed with t-test, ANOVA, Pearson's correlation coefficients and multiple regression, using the SPSS WIN 24.0 program. The average score of social support was 5.71±1.11, avoidance coping style 12.41±3.45, depression 6.33±2.77, and suicidal ideation 6.17±1.87. Suicidal ideation (r=0.292, p<0.001) positively correlated with avoidance coping, and negatively correlated with gender (r=-0.02, p=0.018), number of family (r=-0.12, p=0.008), social support (r=-0.19, p<0.001), and depression (r=-0.24, p<0.001). Results of regression indicated that gender, social support, avoidance coping style, and depression explained 12.8% of variance in suicidal ideation. Therefore, our results indicate the necessity to develop a support program that improves the social support, and addresses avoidance coping style, depression and suicidal ideation, thereby helping to reduce negative thinking amongst the community of seniors aged over 65 years.

This is an investigative study to identify the degree of post-traumatic stress and anxiety of nurses in relation to the COVID-19 pandemic, and to analyze the relationship with the nurse's belief in behavior and control that affects nursing intentions to determine their impact on the belief in behavior. The subjects of this study were nurses with experience of directly nursing COVID-19 patients at medical institutions located in Gyeonggi-do. The SPSS 22.0 version was used for the descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation coefficients and multiple regression. Post-traumatic stress of the participants in this study was found to be 24.20±20.58, anxiety 48.31±6.61, behavior beliefs -1.00±17.12, and control beliefs 3.41±11.66. According to this study, the belief in conduct is negatively correlated with post-traumatic stress (r=-4.71, p<).001) and showed a significant negative correlation with anxiety (r=-2.248, p<.05). There was no significant correlation with control beliefs (p>.05). Based on the results of this study, it is proposed to develop an appropriate psychological arbitration program for mediating post-traumatic stress in order to promote the nurse's behavior beliefs.

This study was designed to investigate the health information usage of immigrants. A questionnaire survey was conducted on 171 immigrants. Data was analyzed for descriptive statistics, chi-square test, and Fisher's exact test. The frequency of migrants' use of health information is low, and the number of respondents who use health information less than once a month is highest. There were statistically significant differences in the frequency of use of health information according to age, occupation, and those who contracted diseases. The main source of health information was the Internet, and there were differences in the sources of health information according to age and whether the Internet was used. Most of the respondents used health information for themselves, and there was a difference in the targets of using health information according having a cohabitee and the perceived health status. It was found that the majority of immigrants do not actively use health information. However, when the age increased or the immigrant was unhealthy, the use of health information increased to solve health problems. Therefore, it is important to provide health information in a variety of ways according to the characteristics of immigrants.

The purpose of the present study is to qualitatively explore childcare teachers' attitudes toward gender sensitivity education for early childhood. The study recruited 227 teachers and directors working in childcare centers around the Seoul metropolitan areas. The study utilised the interpretive science paradigm and visual methods for data collection, and thematic analysis examined the attitudes of 227 participants. Gender sensitivity education include gender flexibility and sexual orientation. Most participants showed positive attitudes toward the gender flexibility education. They regarded the gender flexibility as a topic socially accepted, suitable for early childhood development, and easy to implement. They also believed that the gender flexibility education would encourage the individuality of children. On the other hand, 53.3% of participants showed negative attitudes toward tolerance education regarding sexual orientation. Opponents expressed that an issue of sexual orientation did not reach a social consensus. They also worried that the topic is not developmentally appropriate for early childhood, and difficult to teach young children because of insufficient educational materials. At the same time, 40.5% of participants expected Korean society would embrace diverse sexual orientations in the future, and early childhood education would help young children adapted to changing contexts. This study discussed theoretical concepts of gender sensitivity, listened to childcare teachers' voices about education of gender flexibility and sexual orientation, and suggested more appropriate gender sensitivity education for early childhood.
