The effect of individualized music on agitation for home-dwelling persons with dementia  [PDF]
Heeok Park
Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.36061

Purpose: The purpose of this study was to test the effect of individualized music on agitation for homedwelling patients with dementia. Method: One group pre-post test was used for research design and a total of 26 subjects participated in this study. Individualized music intervention was subjects’ listening to their preferred music for 30 minutes prior to peak agitation time twice a week for a total of four sessions. The subject’s agitation levels were measured for three different points: thirty minutes prior to listening to music, 30 minutes while listening to the music, and after listening to the music throughout the 4 sessions. To measure the agitation level, the modified CohenMansfield Agitation Inventory was used. A Paired ttest was used for data analysis. Results: Most subjects were female (73.1%), Caucasian (92.4%), Protestant (50%), and independent activity (53.8%). The mean of the subjects’ MMSE scores was 8.08 (8.17). The most favorite music types included country/western music (31.0%), religious music (26.9%), and big band (26.9%). Agitation level decreased while listening to the music compared to the baseline (t = 3.70, p < .001). Conclusion: The findings of this study would provide meaningful data to develop an individualized music intervention protocol to control agitation for homedwelling patients with dementia.


Difference in the Contents of Music Intervention to Control Agitation by Music Providers  [PDF]
Heeok Park
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.58077
Abstract: Purpose: The purpose of this study was to compare the contents of music intervention studies between the music therapists and non-music therapists who endeavored to control agitation in patients with dementia, and to provide meaningful ideas to improve the music interventions by music providers. Method: This study is a review study by searching CINAHL, MEDLINE, and PsychINFO for the keywords, “agitation” and “music,” which are used in the searches. Results: A total of 30 studies of music intervention (7 studies about music therapists and 23 studies about non-music therapists) were included for the review. The studies about music therapists had a more reasonable sample size, variety of music activities, and comparison groups. The studies of non-music therapists were provided by nurses, researchers, recreational therapists, and trained nursing assistants and they provided music using background music at a scheduled time for care, such as mealtimes and bathing times. Conclusions: Studies on music interventions need to have a more rigorous research design, such as randomized controlled trials for the future studies. Furthermore, there is a need for multi-disciplinary music intervention studies by music providers who have different types of educational backgrounds and clinical experiences.
Factors Affecting Verbal Agitation in Dementia Patients Living in Nursing Homes, South Korea  [PDF]
Eun Kyung Kim, Heeok Park
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.86028
The purpose of this study using secondary data analysis was to identify factors affecting verbal agitation in patients with dementia staying at nursing home. This study is a secondary analysis of an existing original quantitative data set (n = 193). A total of 166 subjects’ data were included in this current study after 27 subjects’ data were excluded from the original data because they did not appear verbal agitation. Multiple regression analyses identified hallucination (β = 0.27), total number of physiologic discomforts (β = 0.19) and pain (β = 0.17) as significant predictors of verbal agitation and these factors explained 27.8% of the variance in the model. The findings of this study showed that hallucination, total number of physiologic discomforts and pain with dementia need to be considered when intervention programs to control verbal agitation in patients with dementia were developed.
The Effects of Aroma Hand Massage on Fatigue and Sleeping among Hospice Patients  [PDF]
Heeok Park, Youngmi Chun, Sooyoung Kwak
Open Journal of Nursing (OJN) , 2016, DOI: 10.4236/ojn.2016.67054
Abstract: Purpose: The purpose of this study was the comparative effects on fatigue and sleep of aroma hand massage vs. hand massage among hospice patients in a hospital. Methods: The design of this study was a nonequivalent comparison group pretest-posttest design. This study was performed from May to December 2012 in a hospice ward. A total of 30 hospice patients in a hospice ward participated in the study (17 in an aroma massage group and 13 in a massage group). The Piper Fatigue Scale was used to measure the fatigue level. The quantity of sleep was measured using sleep hours and the quality of sleep using the Verran & Snyder-Halpern sleep scale (1987). The aroma massage group used 1:1 lavender and bergamot diluted to 1% with 100 ml jojoba carrier oil. The massage group used carrier oil without an essential oil. Each treatment was performed for 10 minutes prior to the subject’s sleeping time, once a day and for 5 days. Data were analyzed using t-test, x2-test, Fisher’s exact test and the repeated measures ANOVA with the SPSS program. Results: The increase in the fatigue and decrease in the sleep quantity were lower in the aroma hand massage compared to the only hand massage but they were not statistically significant. Conclusion: The quality of sleeping improved in the aroma hand massage group compared to the control group even though it was not significant. For the further studies, assessing and respecting the patient’s aroma preference were important considerations when providing aromatherapy and the appropriation of using 1% essential oil to dilute needs to be tested for the hospice patients in the further studies
Hospice care compliance of nurses working at a hospice ward in Korea  [PDF]
Hyun Gu Lee, Heeok Park, Young Mi Chun
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.42009

Purpose: The purpose of this study was to investigate the hospice care compliance of nurses working at a hospice ward and provide meaningful data to improve the hospice care compliances. Methods: Participants included 104 nurses working at the hospice ward of the hospital located at P and D cities. Data was collected from February to March 2012. The level of hospice care compliance was measured using Bae (2000)’s questionnaires. Data were analyzed with descriptive statistics, t-test, one-way ANOVA and Scheffè test using SPSS/WIN 18.0 program. Results: The level of hospice care compliance in hospice nurses working at a hospice ward was high (3.25 out of 4). In hospice care compliance, the physical area was highest, followed by the emotional, spiritual, and social areas. Hospice care compliance was significantly different according to age, marital status, education, religion, importance of religion, job position, job satisfaction and life satisfaction. Hospice care compliance was also significantly different according to the nurses’ experience of death, having license or certification related to hospice care and experiences related to clients’ death. Conclusions: The findings of this study showed that the level of hospice care compliance was high and the hospice care compliance in South Korea was primarily focused on physical care. Considering that spiritual needs are important needs in hospice clients, hospice nurses need to focus on those aspects more. To improve the quality of hospice care compliance in the hospice nurses, programs to increase hospice nurses’ job and life satisfaction are needed.

Effects of Band Therapy Using Music on Grasping Power, Depression, and Personal Relationships in Nursing-Home-Dwelling Elderly Individuals  [PDF]
Eun Kyung Chang, Heeok Park, Miran Jung, Hae Kyeong Lee, Jieun Park, Mijung Park, Minsuk Gang
Open Journal of Nursing (OJN) , 2016, DOI: 10.4236/ojn.2016.611092
Abstract: The current study examined the effects of band therapy using music on grasping power, depression, and personal relationships among residents of a nursing home. Thirty subjects participated in the study. The band therapy included greetings, warm-up exercises with music, singing with dance, playing instruments, closing speech, and stretching with background music. Band therapy was held for 40 minutes once per week, for a total of four sessions, in the activity room of the nursing home. Findings showed that grasping power, depression, and personal relationships were improved at posttest, but the differences were not statistically significant. A better study design to compare the effects of band therapy with the other group, and a more simple and repeated intervention for the elderly to follow without stress might be necessary.
The Finite-Element Modeling of Dynamic Motions of a Constraint Wind Turbine and the System Diagnosis for the Safety Control  [PDF]
Raiwung Park
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.512123

The aim of this paper is to present a finite element modeling of the dynamic motion of a turbine rotor and its controller design with the mass unbalance under a crack on a rotating shaft. This process is an advanced method to the mathematical description of a system including an influence of a mass unbalance and a crack on the rotor shaft. As the first step, the shaft is physically modeled with a finite element method and the dynamic mathematical model is derived by using the Hamilton principle; thus, the system is represented by various subsystems. The equation of motion of a shaft with a mass unbalance and a crack is established by adapting the local mass unbalance and stiffness change through breathing and gaping from the existence of a crack. This is a reference system for the given system. Based on a fictitious model for transient behavior induced from vibration phenomena measured at the bearings, an elementary estimator is designed for the safety control and detection of a mass unbalance on the shaft. Using the state estimator, a bank of an estimator is established to get the diagnosis and the system data for a controller.

Partially Funded Social Security and Inter-Generational Distribution  [PDF]
Hyeon Park
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.49107
Abstract: This paper introduces a parametric model of partially funded social security system and analyzes inter-generational distribution of consumption and welfare in an OLG general equilibrium. This paper specifically aims to examine the effects of transition toward more funded system on saving and capital accumulation. It is shown that an increase in intensity of fundedness increases capital accumulation unless the income effect from interest rate change outweighs other effects and negatively affects the total saving severely. By deriving closed form solutions for the variables, this paper finds that an increase in the intensity of fundedness increases saving but decreases consumption, when population growth rate is greater than the net return to capital. This paper also finds that for a partially funded system, an increase in tax rate increases public saving but reduces private saving unambiguously, while the effects on consumption and capital accumulation are not conclusive.
Fluid-Structure Interaction Analysis for Drug Transport in a Curved Stenotic Right Coronary Artery  [PDF]
Seungman Park
Journal of Biosciences and Medicines (JBM) , 2016, DOI: 10.4236/jbm.2016.45011
Abstract: A blockage of blood vessels resulting from thrombus or plaque deposit causes serious cardiovascular diseases. This study developed a computational model of blood flow and drug transport to investigate the effectiveness of drug delivery to the stenotic sites. A three-dimensional (3D) model of the curved stenotic right coronary artery (RCA) was reconstructed based on the clinical angiogram image. Then, blood flow and drug transport with the flexible RCA wall were simulated using the fluid structure interaction (FSI) analysis and compared with the rigid RCA wall. Results showed that the maximal total displacement and von Mises stress of the flexible RCA model are 2.14 mm and 92.06 kPa. In addition, the effective injecting time point for the best performance of drug delivery was found to be between 0 s and 0.15 s (i.e., the fluid acceleration region) for both rigid and flexible RCA models. However, there was no notable difference in the ratio of particle deposition to the stenotic areas between the rigid and flexible RCA models. This study will be significantly useful to the design of a drug delivery system for the treatment of the stenotic arteries by targeting drugs selectively to the stenotic sites.

Inho Park, Hyun Soon Park
Advances in Journalism and Communication (AJC) , 2014, DOI: 10.4236/ajc.2014.21001
Abstract: The study aims at developing communication strategies for the public broadcasting system according to WTP (Willingness to Pay) for the subscription fee and the audience’s perception of the public broadcasting system as a public good. A quasi-experiment was conducted for audiences who have previously watched public broadcasting channels. According to the results, those respondents who think of public broadcasting as a public good and who think that public broadcasting performs its public role well have high intention to pay the subscription fee. Respondents feel at a loss when they pay the subscription fee, and the willingness to pay the fee goes down.
