This descriptive investigation aims to identify a relationship between QOL, depression, and anxiety in hemodialysis patients. I conducted this research on 130 subjects aged 19 or above who have received dialysis for at least one month in the hemodialysis unit at N hospital in the city of S. However, it came to 112 as I took out those who either quit, died, or filled out a questionnaire in the incorrect manner. In regards to average points of QOL on a 100-point scale, it is 57.77, demonstrating quite low QOL. Concerning average points of depression and anxiety, it is 12.25 and 10.52, respectively, showing quite a high figure. With regard to a correlation, there is a significant correlation between the three factors in hemodialysis patients: there is a negative correlation between QOL and depression (r=-.782, p<.001); a negative correlation between QOL and anxiety (r=-.719, p<.001); and a positive correlation between depression and anxiety (r=.873, p<.001). The outcome of multiple regression analysis on factors affecting QOL shows that depression is the element influencing QOL (β=-.585). Therefore, this study is significant in providing basic data for establishing intervention strategies aiming to reduce levels of depression which has the strongest impact on QOL in the patients and for developing a nursing intervention program intending to improve their QOL.

This study was conducted for the purpose of identifying the trends of nursing research and to suggest the direction of future research in the graduate levels of the study. The data was collected from 469 abstracts of master's and doctoral rapers from three graduate schools, one in Nursing, another in Education, and the other in Public Health Graduate College. The results of the study are as follows: The number of research was increased from 102 to 286 between the 1970 s and 1980's. The most frequently employed research design was descriptive studies in the master's level, but there was some balance between descriptive and experimental studies along with some qualitative approaches in the doctoral thesis. Patients were the most often studied sample group reaching 42% of the cases, though it Was noted that there was steady shift: toward the non-ratient population. With this shifting of the study sample, the places of the study also have showed some changes moving toward community. The most widely studied area was in clinical practice. Chronic illness, preventive, and health promoting areas of studies also increased in numbers. However, most of them were at the descriptive level of phenomena and only a few were concerned with cost/effective measures of nursing intervention. The number of variables studied repeatedly more than five times was 43. They were not only physical but also psychosocial aspects which imply the efforts to incorporate the whole person in nursing discipline. However, most researches with repeated studies showed little relation to previous studies, and thus little accumulation in knowledge. There was also little evidence of linkage to nursing theory in most studies of master's level. For the doctoral rapers, 17 out of 51 rapers showed specific theories related to the researches. Based on the above findings, the following suggestions were made. Various research design should be employed including case studies, historical studies, as well as qualitative approaches. There should be more effort to establish linkage between theory and research. The areas needing more attention are Korean Nursing History, Ethics in our Culture, Cost/Effective Measures of Nursing Intervention, Concept and Thory Development, and the Strategies for the Implication of the Research Results in clinical practice.

Objective : This study compared the psychological stresses of depressed patients' families with those of schizophrenic patients' families. We investigated the influence of depressive patients' clinical features and their families' demographic characteristics on the families' depressive symptoms and stresses. Methods : Participants were 23 family members of depressed patients and 20 family members of schizophrenic patients. We measured the patients' clinical features (duration of illness, number of previous hospitalizations, and satisfaction with medication), and each family member's socioeconomic status and psychological characteristics (depressive mood, anxiety, family stress, and stress response), analyzing the data via independent t-test, chi-square test, and correlation and hierarchical multiple regression analyses. Results : The depressed patients' average clinical global impression (CGI) was significantly higher than that of the schizophrenic patients. The depressed patients' family members showed stress responses significantly higher than those of schizophrenic patients' family members. Furthermore, in depressed patients, frequency of hospitalization was positively correlated with family members' stat anxiety. For both patient types, family stress was positively correlated with the patient's severity of illness and the family's state anxiety, trait anxiety, and stress response ; socioeconomic status was positively correlated with the family's depressive symptoms ; the family's state anxiety positively correlated with the family's trait anxiety and stress response ; and the family's trait anxiety positively correlated with the family's stress response. Socioeconomic status predicted the family's depressive symptoms, and socioeconomic, illness severity and stress response predicted family stress. Conclusion : These findings suggest that both depressed patients' families and schizophrenic patients' families suffer from psychological stress. The study data also have important clinical implications, in that families of depressed patients need psychiatric intervention, as well as the patients themselves. In particular, family intervention should focus on psycho-education and stress coping strategies.

The purpose of this study was to examine the relationships among child abuse, depression, and smartphone addiction by gender. Data were gathered though questionnaires surveying 1,601 adolescents living in the Seoul and Kyeonggi areas. The results of t-tests and multiple regression analyses using structural equation modeling are as follow. First, approximately 40 percent of adolescents reported having experienced child abuse in the past year. Second, 24.5 percent of adolescents were found to be at risk of smartphone addiction. Third, child abuse was associated with depression and smartphone addiction among adolescents, and depression was found to have a mediating effect on the relationship between child abuse and smartphone addiction. Lastly, gender differences were also found: for male students, child abuse was directly related to smartphone addiction; for female adolescents, depression was found to mediate the relationship between child abuse and smartphone addiction. The results suggest different intervention strategies according to gender and a necessity of intervention to prevent child depression and smartphone addiction. The implications for social work practice were also discussed.

Anger cause heart disease and domestic violence and recently there have been an increasing number of media reports of crimes committed because of their inability to control their anger. Anger has been reported to cause massive financial losses due to heart disease and domestic violence. Therefore, since anger raises serious social problems and social costs, it is necessary to take active intervention methods to alleviate inappropriate anger coping. A variety of methods such as cognitive and emotional approach, psycho-mechanical approach, psycho-educational approach, relaxation therapy, cognitive behavior-art therapy, and stress immunization are being explored and utilized for presenting effective anger-coping intervention alternatives. In this manner, information and communication technology is likely to be used as an effective means for this, and various researches are being conducted. The purpose of this study is to develop an anger coping service technology using ICT (Information & Communication Technology) technology as an effort to improve anger coping ability. In other words, the goal is to develop a technology that delays anger and evokes the surroundings by providing location-based services to recognize anger situations and facilitate anger. This research is about the technology which intervene directly the anger situation to resolve it using location information and introduce the base technology to realize it.

Background: This literature review analyzes 25 studies on the effects of keyboard instrument-based music interventions on cognitive function in older adults. The review shows positive impacts on sensory-motor functions and cognitive domains such as working capacity, attention, and memory. Objective: The purpose of this study is to systematically examine the effects of music interventions using keyboard instruments on cognitive function in late adulthood and evaluate their effectiveness. Method: The studies were analyzed based on participants, methods, tools, interventions, and outcomes, selecting relevant articles published between 2000 and 2023 according to PRISMA guidelines. Results: The analysis showed that keyboard music interventions significantly enhanced cognitive function, particularly in areas such as auditory abilities, attention, and working memory. Pre- and post-intervention tests demonstrated that piano playing significantly improved auditory abilities, attention, working memory, hand function, and brain plasticity. Conclusion: Keyboard instrument interventions positively impact cognitive function in older adults, suggesting their potential for preventing cognitive decline and promoting brain health. This study can guide future studies on the long-term effects and development of optimal strategies.

The study aims to examine Japan's National REDD+ Strategies prepared for Post-2020 and the status of its implementation by organizations in Japan, and then to suggest the potential REDD+ countermeasures against Joint Credit Mechanism (JCM) for Republic of Korea and their implications. As for the technical limitations of the guidelines of REDD+ under the JCM, it is pointed out that forests located at the place with less potential safeguard intervention tend to be selected as the target area for a project and that, as reference emission trend changes depending on the basic year of the baseline, differences could occur among the amounts of greenhouse gas emission. In addition, it is pointed out that the result of the calculation of the displacement of emissions, or leakeage, in REDD+, can have an uncertainty, since the calculation is done by just multiplying leakage area by certain coefficients, without considering the size of the leakage area. Furthermore, the lack of implementation guideline or methodologies for a project level is also pointed out as a limitation, considering that there are only some national and sub-national monitoring guidelines at present. Finally, internationally accepted guidelines for safeguard and its sub-items needed to be prepared, as current safeguard policy only includes lists without detailed items. Such things mentioned above are all related to, and can lead to the problem of double counting of items in Nested Approach etc., as well as of the distribution of credits. Therefore, Republic of Korea should take these into consideration when implementing its REDD+ projects.

The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in selfefficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

The purpose of this study was to construct a grounded theory as the basis for nursing intervention by describing and analysing the holistic lived experiences of clients receiving long-term hemodialysis. The subjects of this study were fifteen persons receiving regular hemodialysis regimen at artificial kindey treatment centers in two different university hospitals, and who were able to participate in conversation and were available for long and dup interviews. Eight of the subjects were male and seven were female and their ages ranged from 30's to 60's. The length of the hemodialysis experience ranged from two months to six years. The collection and analysis of data were done in accordance with the grounded theory methodology of Strauss & Corbin. The method to collect the data mainly depended. on long and deep interviews, participant observation and focused group interviews and the equipment used to collect data were a portable tape recorder and field notes. The study is summarized as follows : 1. The meaning of holistic lived experiences of clients receiving long -term hemodialysis was found to be uncertainty. which was identified as the core category. 2. The main categories following the core category were found to be shock, ambiguity, social support and quality of life. 3. Through the main category the type of behavior newly formed by clients receiving long-term hemodialysis was found to be as follows. That is to say, in the circumstances of shock caused by the identified fact and the ambiguity of hemodilysis they formed a quality of life based on social support, which was found to be a kind of chaotic phenomenon. 4. The lived experiences of clients receiving long-tern hemodialysis was found to include nine categories : emotional shock, feelings of isolation, burden, unclearness, dependency, help from others, coping strategies, maintenance of self-esteem and transitional life. 5. The intervening factors influencing each category are as follows : 1) The factors influencing 'emetional shock' were found to be set age, the level of knowledge received in advance, locus of control, the period of struggle against the disease before hemodialysis and whether any serious illness existed. 2) The factors influencing 'feelings of isolation' were found to be religion and the length of the hemodialysis experience. 3) The factors influencing 'burden' were found to be sex, economic situation, employment status and the length of the hemodialysis experience. 4) The factors influencing 'unclearness' were found to be sex, age, religion. economic situation, the length of the hemodiaysis experience, whether they had had a transfusion and whether there were any complications. 5) The factors influencing 'help from others' were found to be religion. economic situation, past experiences and whether family members lived together. 6) The factors influencing 'coping strategies' were foung to be age, level of education, experiences of illness and locus of control. 7) The factors influeruing 'maintenance of self-esteem' were found to be the length of the hemodialysis experience and self-actualization. 8) The factors influencing 'transitional life' were found to be age, religion, economic situation, employment status. locus of control. past experiences and whether there was a plan for a kidney transplant.

Understanding of how teachers change instruction can help predict what kind of educational materials is supportive or appropriate. On the basis of this idea, we explored elementary teachers' PCK progression on specific topics of astronomy: planet size and distance in solar system. To identify the development of PCK over time, we utilized learning progression (LP) as a conceptual framework. The progression of teacher PCK can also be illustrated as the hypothetical pathway from novice to expert like LP. Eight 5th grade elementary teachers participated in this study. We observed participating teachers' astronomy classes with the same topic. In order to document topic-specific PCK of participating teachers, we developed an analytic protocol consisting of four categories: knowledge of curriculum, knowledge of teaching strategies, knowledge of assessment, and astronomical thinking practice. In addition, we monitored the changes in the four participating teachers' PCK for two years in order to validate the evidences of the PCK progression. Participating teachers in this study took some intervention by attending a four-week pre-meeting with the researchers to profile an adaptive instruction. Through this research, we profiled four and five different levels of PCK progressions in three knowledge components (curriculum, teaching strategies, student assessment) and one astronomical thinking practice (systems thinking), respectively. Participating teachers demonstrated various levels and pathways in each component of PCK. This study released the empirical evidences in fostering instructional scaffolding, which is appropriate to the level of PCK of science teachers on specific topic.
