Purpose: This study aims to develop the Korean version of Presenteeism Scale for Students and verify its reliability and validity. Methods: This study conducted a survey with 320 undergraduate students who are attending nursing departments at three universities. The survey was conducted twice, from June 1 to August 31, 2017. Results: The Cronbach's α of K-PSS was .70 indicating high reliability. As a result of testing the content validity of K-PSS was verified by calculating the Item level-Content Validity Index (I-CVI) of .87. The correlation between Medical Outcome Study 36-item Short Form Health Survey (SF-36) score and Work Impairment Score (WIS), Work Output Score (WOS), Hours of absenteeism (HA) was analyzed to verify the concurrent validity of K-PSS. SF-36 score was correlated with WIS, WOS, HA. To test the differentiated validity of K-PSS, a total of 38 subjects were assessed by the paired t-test. As a result, only WIS score showed a significant difference between pre-test and post-test. Conclusion: Since the reliability and validity of the K-PSS developed through this study have been verified, it is expected to be used in various studies related to the presenteeism of students.

Objective : This study aimed to investigate differences in demographic, clinical characteristics, and quality of life between panic-disorder patients with generalized anxiety disorder (PD+GAD) and without generalized anxiety disorder (PD-GAD). Methods : We examined data from 218 patients diagnosed with PD+GAD (150 patients) and PD-GAD (68patients). The following instruments were applied: Stress coping strategies, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Panic Disorder Severity Scale (PDSS), Anxiety Sensitivity Index-Revised (ASI-R), Albany Panic and Phobia Questionnaire (APPQ), NEO-neuroticism(NEO-N), Short Form health survey-36 (SF-36). Results : Compared to the PD-GAD group, the PD+GAD group had higher scores in emotion-focused coping strategies and clinical severity, such as BDI, BAI, PDSS, ASI, APPQ, and neuroticism. The PD+ GAD group showed lower scores in most scales in SF-36 status than PD-GAD group. Conclusions : This study shows that PD+GAD patients are different from PD-GAD patients in coping strategies, clinical severity and quality of life. It emphasizes the need of personalized therapy in clinical approach among patients with PD+GAD.

This study aimed to know the association between health practices(Alameda 7) and health state according to Sasang Constitution. We recruited 204 subjects whose age were between 10 and 80, excluding individuals who have physically or psychologically serious diseases, and women in pregnancy among Korean population in Traditional Korea Clinics. They were diagnosed by Sasang constitution specialists and confirmed clinically with Sasang constitution drug response with past medical records. We used the 36-Item Short Form Health Survey(SF-36) to estimate health state related with quality of life. We statistically analyzed association using SPSS 17.0K for window. According to Sasang Constitution, smoking and exercising were associated with health degree in Tae-eumin, smoking, drinking, diet and snacking in So-eumin, and past smoking, drinking, sleeping and exercising in So-yangin. These results suggest that there are different health practices for health promotion according to Sasang constitution. Therefore we have to consider the differences of Sasang constitution in health care plan.

In marine controlled-source electromagnetic (CSEM) modeling, it may be difficult to evaluate primary fields accurately using conventional linear filters because they decay very rapidly with distance. However, since there exists a closed-form solution to the Hankel transform in TM mode for a homogeneous half space, we can assess the accuracy of linear filters for evaluating the Hankel transform. As a result, only nine out of 36 source-receiver pairs show that EM fields decrease linearly in semi-log scale with an increase of source-receiver distance, while EM fields are either 0 or not reduced significantly due to an effect of the air layer. There also exist closed-form solutions for the nine pairs, and the others can be evaluated accurately with a relatively short filter. This paper proposes a method which uses closed-form solutions for TM-mode Hankel transforms and a filter with 61 coefficients for TE-mode ones.

1. Objectives: Sasang Medicine has been based on different medicine approach because people were different, so, this was a little different concept about health compared to other oriental and western medicine focused on existing Yangsaeng theory. We were announced Constitution health indicators for women, and this was follow-up study designed to identify Constitutional health indicators in men. 2. Methods: We recruited 171 men between 10 and 80, excluding individuals who have physically or psychologically serious disease among Korean population in Traditional Korea Clinics. They were diagnosed by Sasang Constitution specialists and confirmed clinically with Sasang constitution drug response with past medical records. We used CRF(Case Report Form, C-2009-002439) as measurement of physiological and pathological symptoms and SF-36 (Short Form-36) as measurement of health state. We analyzed association between physiological and pathological symptoms and health state with Two-way ANOVA. 3. Results: 23 items of 82 indicators in physiological and pathological symptoms were related to the quality of life, regardless of the constitution. There are 4 different symptoms associated with health state in men, such as regular of feces, hard to fall asleep, no problem in chest, feel heavy in chest according to Sasang Constitution. 4. Conclusions: From these Results, there are different items of physiological and pathological affected the Quality of life according to Sasang Constitution.

Objectives More than half of the elders suffer from chronic sleep disturbances. Moreover, sleep disturbances are more prevalent in patients with depressive disorder than in community dwelling elderly. In this study, we aim to estimate the risk factors of poor sleep quality and its effect on quality of life in patients with late life depression. Methods This study included 159 depressive patients aged 65 years or older who completed Pittsburgh Sleep Quality Index (PSQI). A global PSQI score of 5 or greater indicates a poor sleeper. Structural diagnostic interviews were performed using the Korean version of Mini International Neuropsychiatric Interview (MINI). Depression was evaluated by the Korean form of Geriatric Depression Scale (KGDS). Global cognition was assessed by Mini-Mental State Examination in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment packet. Quality of life was evaluated by the Korean version of Short-Form 36-Item Health Survey (SF-36). Results The frequencies of poor sleepers were 90.5% in major depressive disorder, 71.8% in minor depressive disorder, 47.1% in subsyndromal depressive disorder, and 73.0% in all types of depressive disorders. Multivariate logistic regression analysis indicated that female [odds ratio (OR) = 2.83, 95% confidence interval (CI) = 1.20-6.67] and higher KGDS score (OR = 1.13, 95% CI = 1.05-1.21) were risk factors of poor sleep quality in patients with late life depression. In the analysis of ANCOVA adjusted for age, gender, education and KGDS score, the mean scores of vitality mental health and mental component summary of SF-36 were lower in poor sleepers than in good sleepers. Conclusions Poor sleepers among patients with late life depression are very common and are associated with female and higher KGDS scores. Poor sleep quality causes a significant negative effect on mental health quality. So researchers and clinicians should be more vigilant in the evaluation and treatment of sleep disturbances in patients with late life depression.

Background and Objectives: The purpose of this study was to examine the relationship between between one's quality of life (QoL) level and the arterial stiffness estimated by the second derivative of photoplethysmogram (SDPTG) for women patients. Methods: A retrospective chart review was performed on charts of 407 women patients (38.38±11.82 years) who visited Gangdong Kyung Hee Hospital between April 1st and September 30th, 2011. Vascular aging index (VAI, (b-c-d)/a), b/a, c/a, and d/a were considered as the arterial stiffness indexes, and the Korean version of the Short-Form 36 (SF-36) were completed to estimate one's physical and mental QoL. Results: Physical and mental components of the SF-36 in older group (50, 60, and 70 years-group) were lower than those in younger group (20 and 30 years-group). Large arterial stiffness-related b/a in older group was higher that in younger group, while small arterial stiffness-related d/a in older group was lower that in younger group. Physical and mental component scores of the SF-36 had the negative correlations with VAI and b/a (r; -0.153~-0.195), while had the positive correlations with c/a and d/a (r; 0.147~0.228). Conclusions: In conclusion, this study suggests that convenient and cost-effective SDPTG test may serve as an auxiliary tool to estimate one's physical and mental QoL.

Purpose: This study examine the functioning level and quality of life (QoL) of people with non-specific neck pain and neck pain with radiculopathy using the neck disability index (NDI), functional rating index (FRI), and short form of health survey 36 (SF-36) and each of linked lCF code lists of those scales. Methods: Each item of the NDI, FRI, and SF-36 were linked conceptually to the ICF code, and the lCF code lists of those scales were produced as iNDI, iFRI, and iSF-36, respectively. Seventy-nine patients with neck pain filled the instruments and its linked ICF code lists. The subjects were divided into two groups based on the diagnosis, non-specific neck pain (Group1), and neck pain with radiculopathy (Group2). A group comparison was performed using an independent t-test. The Pearson correlation coefficient was also used to analyze the relationships between each scale and the linked ICF code list. Results: The participants in Group 2 experienced more difficulties in their daily activities than those in Group 2 when examined in NDI and FRI (p<0.05). This result was also found consistently in the ICF code lists, iNDI and iFRI (p=0.05). On the other hand, the QoL did not show a difference between groups (p=0.06). A strong correlation was observed between the instruments and linked ICF code lists: NDI and iNDI (r=0.90), FRI and iFRI (r=0.91), and SF-36 and iSF-36 (r=-0.61). Conclusion: These findings suggest that the concept of each item in NDI and FRI could be linked to the ICF codes when examining patients with neck pain, but the items of SF-36 were found to be linked and expressed in ICF.

The purpose of this study was to examine symptom experiences, sleep quality, and quality of life in asthma patients and investigate any correlation among these factors. The study was conducted on 146 asthma patients that visited the Internal Medicine Department of Allergies at a hospital in Korea from March to June, 2015. Tools that were originally developed by Oh (1999) were used to measure the symptom experience of asthma patients. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) while quality of life was measured by the Short Form 36-Items Heath Survey (SF-36). The dates were analyzed by t-test, ANOVA, Scheffe test, and Pearson's correlation coefficient using the SPSS 20.0 program. Symptom experiences of asthma patients showed a positive relation with sleep quality (r=.468, p<.001) and negative relationship with quality of life; PCS (r=-495, p<.001) and MCS (r=-.411, p<.001). The symptom experiences of an asthma patient along with sleep quality and quality of life turned out to be correlated. Therefore, this study is expected to be utilized as a basis for the development of assessment tools and arbitration programs to elucidate symptom experiences of asthma patients from various aspects and enhance their sleep quality and quality of life.

This study was conducted to evaluate the effect of forest environment and therapeutic program to the patients with major depressive disorder in antidepressant medication. The first group participated the four sessions of therapeutic program in the forest environment ("forest therapy"), the second group did in the program in a hospital environment, the third group did merely walking in the forest ("forest bath"), and the last group was controls. All the participants was diagnosed with major depressive disorder and had been taking antidepressant medication longer than 3 months. Depressive symptoms were measured by the Hamilton Rating Scales for Depression(HRSD), Montgomery-Asberg Depressin Rating Scales(MADRS), Beck Depression Inventory(BDI), and general health perception was measured by Short Form Health Survey Questionnaire(SF-36). Heart rate variability(HRV) were also examined to observe the physiological parameters before and after the program. In the results, HRSD score of forest program group was significantly lower than controls after the program. MADRS score of forest therapy group and hospital program group was also significantly lower than controls after 4 sessions of the program. The remission rate defined as below 7 points in HRSD was higher in the forest therapy group, hospital program group, forest bath group, and controls in order. These results reveals that the therapeutic program performed in forest environment may improve unremitted depressive symptoms of patients with major depressive disorder. Although not significant, the forest therapy program showed better outcome than hosptial program and forest bath.
