Objectives : The aim of this study is to investigate the relevant factors which determine the use of oriental healthcare services among subjects with chronic illnesses. Method : This study utilized the data from the Korean National Health and Nutrition Examination Survey in 2005. Out of all the participants of the survey, 11,665 individuals who are older than 19 years old and have one or more chronic diseases were included in this study. Results : The factors that affect utilization of oriental healthcare services were significantly associated with gender, educational level, job, personal income, the number of chronic illnesses, experiences of nontreatment or delayed treatment and admission experiences for the last one year(p<.001). Although some of these factors need further studies, the determining factors for the use of oriental healthcare services are the presence of chronic illness and the number of chronic disease. That is, the chronically ill are more likely to seek oriental healthcare services. And the more chronic diseases the clients have the higher probability of seeking oriental healthcare services was found. Conclusions : The results suggest that the national integrated care services should be established for diverse development of policy regarding the quality of care of chronic illness and cost-effectiveness.

This study was conducted to (a) investigate the frequency of Korean beverage consumption, (b) analyze the characteristics of socio-demographically classified group according to drinking frequency, (c) investigate the attitude for and awareness of Korean beverage and (d) analyze the factors which influence Korean beverage consumption. The survey was carried out by self-administered questionnaires with 2,200 subjects residing in Seoul. A total of 1,885 samples were used for analysis by using t-test, one way analysis of variance (ANOVA), Duncan's multiple comparison test, factor analysis, and analysis of covariance (ANOCOVA) with SAS computer program. Among various Korean beverage, Donggulre tea was consumed most frequently at an average of 7.4 times per month, and followed by rice beverage, Mi Su, Citron tea, Shick Hae and canned Shick Hae. Among the age groups, the group of 20s showed the lowest frequency of Korean beverage consumption exempt rice beverage. According to occupation group, middle and high school and college student groups showed a high frequency of consumption of cereal based drink such as rice beverage, Mi Su and Yulmu tea. The behavior examination aimed at learning the perceptions relevant to the choice of beverage showed that the subjects believe Korean beverage healthful and nutritious but not familiar through advertisement, not easy to buy, and not to be a habitual drink. The factors influencing the frequency of Korean beverage consumption were shown as health-related factors and habitual/practical factors.

Purpose: The purpose of this study was to investigate the factors that increase of the risk for falls in low-income elders in urban areas. Methods: The participants were elderly people registered in one of public health centers in one city. Data were collected by interviewing the elders, assessing their environmental risk factors, and surveying relevant secondary data from the public health center records. For data analysis, descriptive statistics and multiple logistic regression were performed using SPSS version 14. Results: Stroke, diabetes, visual deficits, frequency of dizziness, use of assistive devices and moderate depression were statistically significant risk factors. The comorbidity of chronic diseases with other factors including depression, visual deficit, dizziness, and use of assistive devices significantly increased the risk of falls. From multiple logistic regression analysis, statistically significant predictors of falls were found to be stroke, total environmental risk scores, comorbiditiy of diabetes with visual deficits, and with depression. Conclusion: Fall prevention interventions should be multifactorial, especially for the elders with stroke or diabetes, who were identified in this study as the high risk group for falls. A fall risk assessment tool for low-income elders should include both the intrinsic factors like depression, dizziness, and use of assistive devices, and the extrinsic factors.

Parkinson's disease (PD) is a common neurodegenerative disorder characterized by selective and progressive loss of dopaminergic neurons. Genetic and environmental risk factors are associated with this disease. The genetic factors are composed of approximately 20 genes, such as SNCA, parkin, PTEN-induced kinase1 (pink1), leucine-rich repeat kinase 2 (LRRK2), ATP13A2, MAPT, VPS35, and DJ-1, whereas the environmental factors consist of oxidative stress-induced toxins such as 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP), rotenone, and paraquat. The analyses of their functions and mechanisms have provided important insights into the disease process, which has demonstrated that these factors cause oxidative damage and mitochondrial dysfunction. The most invaluable studies have been performed using disease model organisms, such as mice, fruit flies, and worms. Among them, Drosophila melanogaster has emerged as an excellent model organism to study both environmental and genetic factors and provide insights to the pathways relevant for PD pathogenesis, facilitating development of therapeutic strategies. In this review, we have focused on the fly model organism to summarize recent progress, including pathogenesis, neuroprotective compounds, and newer approaches.

Purpose: This study aimed to investigate the risk factors for cardiac implantable electronic device (CIED)-related infections within the first post-procedural year after CIED insertion. Methods: This study included 509 adult patients undergoing CIED implantation procedures between January 1, 2011 and December 31, 2015. The data were analyzed by t-test, chi-square test, Fisher's exact test, and logistic regression analysis using SPSS/WIN 23.0. Results: Fifteen infections and 494 non-infections were examined. The CIED-related infection rate was 2.9%; patients with 14 pocket infections and one bacteremia were included in the CIED-related infection. The risk factors of CIED-related infections were the estimated glomerular filtration rate (eGFR) of ≤ 45 mL/min/1.73 m² (Odds ratio [OR]= 4.03, 95% confidence interval [CI],1.15-14.10) and taking a new oral anticoagulant (NOAC) (OR = 4.50, 95% CI 1.09-18.55). Conclusion: These results identified the CIED infection rate and risk factors of CIED-related infection. It is necessary to consider these risk factors before the CIED implantation procedure and to establish the relevant nursing interventions.

Purpose - This paper empirically investigates via a spatial lag model from the perspective of space economy to find the influencing factors of South Korea's OFDI along with 60 countries. Design/methodology - In the study of regional economic phenomena, we must first test the corresponding spatial correlation, and on this basis, complete the construction of the spatial model. For the target research object, after testing the spatial correlation, if there is spatial correlation, a spatial measurement model is needed. This paper uses the global Moran's I index for calculation. Based on the characteristics and research needs of the research object, this paper selects the spatial lag model to verify the existence of the spatial effect and factors affecting OFDI. Findings - Our results show that export scale, infrastructure, technology level, political stability, resource endowment, market size, distance and labor cost have a certain impact on Korea's OFDI, but at present the distance and market size factors are the most important influencing factors for South Korea's OFDI, The technical level and political stability have little effect on South Korea's OFDI, and are not main factors determining South Korea's OFDI. Originality/value - Through spatial measurement verification, it was found that the spatial effect has a significant impact on OFDI, along with more than 60 countries. On this basis, relevant suggestions are put forward, which have strong practical significance for South Korea's OFDI to achieve healthy and sustainable development.

Objectives: Adolescents are at risk of suicide. As suicide is a multifactorial process, risk and protective factors are relevant constructs for suicide prediction. This study explored the effects of risk and protective factors on suicidal ideation in adolescents on the island of São Miguel (Azores). Methods: A sample of 750 adolescents (male: n=358; 47.7%; mean age=14.67 years; standard deviation=1.85 years) from the island of São Miguel (Azores) completed several measures related to suicidal ideation and associated factors. Using a cross-sectional design, this study conducted descriptive, correlational, predictive, mediation, and moderation analyses. Results: Adolescents generally displayed high levels of risk and protective factors; an indicative proportion exhibited significant suicidal ideation with females presenting the greatest vulnerability. Furthermore, the results highlight that depression is the best predictor of suicidal ideation, however, the association between these variables is mediated. Conclusion: The data corroborate that the suicidal reality of adolescents in the Autonomous Region of the Azores is worrisome. Having substantiated the complexity of the suicidal context in young people in the present research, the need to continue studying risk/protective factors in this area is supported.

Objectives : This study was performed to analyze treatment outcomes of idiopathic and secondary frozen shoulder patients with clinical characteristics, as well as percentage of pain reduction, and to find out relevant factors for pain reduction in the frozen shoulders of each patient group. Methods : Data were collected from outpatients who visited the Acupuncture and Moxibustion department and treated with traditional Korean Medical treatments at a Korean Medicine Hospital from June 12, 2006 to June 30, 2015. Patients were divided into two groups; idiopathic and secondary frozen shoulder, based on imaging and medical records. Clinical characteristics (demographic characteristics, disease characteristics, treatment characteristics) and percentage pain reduction were collected. Percentage pain reduction was compared between two groups and relevant factors for pain reduction were analyzed. Results : 78 outpatients'medical records were reviewed. There was no significant difference of clinical characteristics between idiopathic and secondary frozen shoulder patients. In percentage pain reduction, there was no significant difference between the two groups. In the idiopathic frozen shoulder group, patients who had a short duration from the onset had a tendency for less pain (p<0.05). In the secondary frozen shoulder group, patients taking herbal medicine experienced significantly less pain (p<0.05). Conclusions : We could find no significant difference in percentage pain reduction with traditional Korean medicine between idiopathic and secondary frozen shoulder. Duration from the onset could be relevant in percentage pain reduction in idiopathic frozen shoulder, and taking herbal medicine could be relevant in the percentage pain reduction in secondary frozen shoulder.

본 연구에서는 초음파 검사 시 정상인을 대상으로 연령대에 따른 신장 기능 지표와 신장 크기 간의 상관관계를 분석하고자 하였다. 복부 초음파 검사를 실시한 정상인 170명(남:86명, 여:84명)을 20대, 30대, 40대, 50대 이상으로 분류하였다. 피검사자는 옆으로 누운 자세로 좌/우측 신장을 2번씩 신장 길이와 너비 그리고 단면적으로 신장 크기를 측정하였다. 이때 신장 길이는 최대 상극에서 최대 하극까지 측정하고 같은 초음파 영상에서 가장 넓은 너비를 계측하여 단면적을 구하였다. 그 외 관련인자로 체표면적, 혈중크레아티닌, 사구체여과율, MDRD (Modification of diet in renal disease), C-G (Cockcroft-Gault)를 조사하였다. 성별에 따른 연령대별로 관련인자 간의 유의한 차이 비교는 일원배치분산분석으로 실시하였다. 또한 관련인자들 간의 상관관계 분석을 시행했으며 Pearson과 Spearman correlation coefficient를 이용하였다. 이때 p 값이 0.05보다 작을 때 유의성이 있다고 정의하였다. 그 결과, 신장의 길이, 너비, 단면적 등은 사구체 여과율, C-G, MDRD와 상관관계가 있었다. 따라서 신장 초음파 검사 시 신장 길이 하나만을 측정하기보다는 관련 인자를 함께 평가한다면 신장 질환에 진단 정확도를 높일 수 있으리라 기대한다.
