This paper proposes healthcare bathing system for improving the multisensory function and not washing. We designed various types of bathtub for developing bathing system. This system consists of whirlpool bathtub for multisensory stimulation, a cover of bathtub with visual-auditory stimulation function, a small size PC for main control, touch panel, digital multimedia broadcasting (DMB), color-changeable LED mood lighting system for improving visual sensibility and speaker. We investigate the effects on autonomic nervous system during bathing with healthcare bathing system for improving the multisensory functions. To analysis physiological parameter, body temperature, blood pressure, intraocular pressure and heart rate variability (HRV) were measured before, during and after bath using healthcare bathing system. Experiments were performed on partial immersion bath and the water temperature was kept $39{\pm}0.5^{\circ}C$. The body temperature and the heart rate variability of the subject were measured every 5 minutes before, during, and after the bath. In analysis of HRV, the parasympathetic nerve increased from starting bath and decreased after 15 minutes. So the subjects felt comfortable at 15 minutes after starting bath. Blood pressure decreased to 16mmHg maximumly however pulse increased. Bath using healthcare bathing system for improving the multisensory functions affects positively the circulation of the blood. From this results, it leaves something to be desired in evaluation of serviceability and physiological analysis using the healthcare bathing system, however, we expect to analyze more clearly the relationship between the serviceability of product, physiological change and sensibility by various physiological parameters.

Objective : Chronic posttraumatic stress disorder (PTSD) is defined by the coexistence of symptoms (reexperiencing, avoidance and hyperarousal), persisting for more than months or years that causes significant impairment in social occupational functioning. This study was conducted to evaluate the effects of terazosin on posttraumatic nightmares which is one of chronic PTSD symptoms. Methods : Twenty patients with chronic PTSD and severe trauma-related nightmares were treated with terazosin (3-7 mg/day) for 8 weeks. Recurrent distressing dreams item of the Clinician administered PTSD Scale (CAPS), Total CAPS score, Clinical Global Impressions-Severity Scale (CGI-S) and Clinical Global Impressions-Change Scale (CGI-C) were performed at baseline, 4-week and 8-week. Mississippi Scale for Combat-Related PTSD and Combat Exposure Scale (CES) were used to evaluate PTSD symptom pattern and degree of exposure. Results : Significant decrease in recurrent distressing dreams item, reexperiencing, avoidance and hyperarousal symptom score and total CAPS score were at 4-week and 8-week treatment compared to baseline (recurrent distressing dreams item : $2.70{\pm}1.88$ and $1.25{\pm}1.49$ ; reexperiencing, avoidance and hyperarousal symptom score : $2.30{\pm}2.49$, $1.20{\pm}1.05$, $3.10{\pm}1.68$ and $4.00{\pm}3.59$, $1.55{\pm}1.50$, $5.60{\pm}3.23$ ; total CAPS score : $8.20{\pm}6.26$ and $5.40{\pm}5.89$). There were significant correlation between dosage of terazosin and improvement of PTSD symptoms. Adverse effects such as fatigue and orthostatic hypotension were showed, which were mild and self-limited. Conclusion : These results suggest that terazosin may improve severe trauma-related nightmares and overall PTSD symptoms. Randomized controlled study with more subjects would be necessary in the future.

Along with the mood of 'Beyond GDP', it is necessary to explore how these subjective concepts such as happiness and well-being are quantified to be compared among many countries. The concept of 'Work-life balance (WLB)' is likely to be located on the boundary between the subjective and objective areas. Thus, this article aims to examine the policies related to WLB and how to change or develop those policies considering the concept of WLB and the circumstantial particularity of Korea. There are several suggestions on certain developments in the existing policies interfering WLB at three levels. First the government needs to conduct campaigns to transform traditional gender roles through active advertisement. Second, the company needs to use the long-lasting 'hierarchical organisation culture' for employee's work-life balance for regulating working hours and exhausting paid holidays and maternity or paternity leave. Finally, families should understand and support their wives' current circumstances facing the struggle between a mother and economic worker.

The effort to make the peaceful mood between South and North Korea that had started from so-called 'Sunshine Policy' of the People's Government since 1998, lasted until Rho Mu-hyun government. On the other hand, Lee Myung-bak government changed the policy toward North Korea to more practical and principle-oriented one than the previous two governments. By the shift of the policies, the industry of animation of South and North Korea has been influenced so much. The purpose of his study is to point out the crisis of the status of the animation industry of the Korean Peninsula through the change of the policies, and to propose one method of the new paradigm to the next government in order to build a turning point of South and North Korea animation exchange. First, the paradigms toward North Korea through the past governments are compared. Second, the result and situation of animation industry of South and North Korea are analyzed. Finally, by examining deducted problems, the forward policy toward North Korea and, by extension, the improvement direction and practical tasks of South and North Korea animation exchange policy are considered.

Objective : Using patterns of change in heart rate variability (HRV), we investigated the effects of stress exposure and type of anger expression on cardiovascular diseases. Methods : Eighty-nine medical students were evaluated by STAXI-K, BDI, BAI, and measured HRV. According to the scores of anger expression questions in STAXI-K, objects are comparted to three groups. Each group is compared with others on the levels of depression, anxiety and HRV. Additionally objects are divided into two groups of functional anger expression group and dysfunctional anger expression group, and each group also divided into two groups, depending on the exposure of stressful situation or not. Members who took part in the stress exposure groups, they've got a serial arithmetic process for five minutes. We surveyed patterns of HRV in 4 each groups and estimated interactions between existence of stressful situation or type of anger expression and HRV. Results : Irrespective of stress manipulation, the dysfunctional anger expression group showed a marked increase in the LF/HF ratio in comparison to the functional anger expression group. Also, under conditions of stress manipulation, the stress exposure group exhibited a relatively increased level of TP. It can't be discriminated any correlations between stress manipulation and type of anger expression. Conclusion : Both of them, exposure to the stressful situation and type of anger expression, have influence on cardiovascular diseases. By controlling anger and way of express that, it is possible to diminish the incidence of cardiovascular diseases.

This study investigated how people who became blind midway through life used music and how these uses differed according to individual factors. Sixty-one late-blind adults aged 40 to 60 years attending six welfare centers for the blind in Seoul and Gyeonggi region participated in this research. Participants were asked to complete a 25-question survey in Braille on music utilization and preference, as well as the purpose of music utilization. The response rate was 87.1%. The results were as follows. First, with regard to listening preference, they reported preferring to listen to upbeat popular music on the radio when resting at home. They liked to sing along to lyrics reminiscent of personal memories. String instruments were preferred when playing an instrument. With regard to the reason for using music, inducing mood change was found to be the biggest reason, followed by seeking enjoyment, comfort, sense of achievement, and sense of belonging. Third, for people with adventitious visual impairments, individual factors, such as gender, level of disability, and period without eyesight, did not reveal any significant differences. Last, participants were found to obtain a higher sense of belonging through music compared to those having low vision. Regarding time without eyesight, it appeared that the shorter the period, the higher the sense of belonging participants had from utilizing music, and vice versa. This study provides fundamental information for organizing an effective music program that can meet the needs and demands of people with adventitious visual impairments.

Objective : The present study had examined the psychiatric symptoms and physical health consequences for the bereaved parents of the high school students who died in the 2014 Sewol ferry accident. Methods : Forty bereaved parents participated in the study. The authors administered self-report questionnaires about the parents' health behaviors and psychiatric symptoms. The authors also conducted laboratory tests to assess the parents' physical health at 18 and 30 months after the accident. Univariate descriptive statistics were performed to report the prevalence and severity of psychiatric symptoms and health-related behaviors. Paired t-test and Mcnemar test were performed to compare the 18-and 30-month findings. Correlation analysis between psychiatric symptoms and laboratory findings were performed to find a relationship between the two variables. Results : At 30 months after the accident, most of the bereaved parents still appeared to suffer from complicated grief (97.5%), post traumatic stress disorder (80%), insomnia (77.5%) and severe depression (62.5%) based on the scores on the Inventory of Complicated Grief (ICG), the PTSD Check List-5 (PCL-5), the Insomnia Severity Index (ISI) and the Patient Health Questionnaire-9 (PHQ-9). One quarter of the bereaved parents reported high-risk drinking, and 47.5% reported increased drinking amount and frequency after the accident. In objective laboratory results, 55% of the bereaved parents were obese as defined by body mass index ${\geq}25$. The parents' mean low-density lipoprotein shows a significant increase over time (118.5 mg/dL at 18 months. vs. 132.5 mg/dL at 30 months. paired t-test t=-4.061, $$p{\leq_-}0.001$$). Total cholesterol and low-density lipoprotein at 30 months after the accident were in clinically borderline high range. In correlation analysis, triglyceride was positively correlated with ISI. Conclusion : The loss of children in the Sewol ferry accident, a disaster caused by human error, continued to have considerable impact on the victims' parents' mental and physical health 18 and 30 months after the accident. A longitudinal study following the parents' physical health would be necessary to investigate the long-term effects of this traumatic experience on physical health.

The purpose of the study is to investigate the predisposing factors of posttraumatic stress disorder (PTSD) in fire fighters in Korea and to suggest the program development and solution to the critical incident stress management (CISM) in the future. PTSD is characterized by invasion, withdrawal, negative change of cognition and mood, and hypersensitivity. Trauma memory includes explicit memory and implicit memory. The explicit memory is conscious, cognitive, and descriptive and is controlled by hippocampus. The data of explicit memory have inhibitive and narrative language structure. The implicit memory is inconscious, emotional, and remembered by the body. The implicit memory is controlled by amygdala and has inexpressive language structure. The deletion of implicit memory is the key point to trauma treatment. Critical incident stress management (CISM) is the approach for the solution of PTSD. In conclusion, the essential goal of CISM is the psychological cessation of PTSD. This study tried to suggest the education program development of PTSD.

Needs for Smart Grid development are increasing all over the world as a solution to its problem according to depletion of energy resources, climatic and environmental rapidly change and growing demand for electrical power. Especially decentralized power is attracting world's attention. In this mood a new era for a unit scale of decentralized power environment is on its way in building. However there is a problem to have to be solved in the uniformity of power quality because the amount of power generated from renewable energy resources such as wind power and solar light is very sensitive to climate fluctuation. And thus this paper tries to suggest an energy management algorithm on basis of real time monitoring for meteorological data. The proposed EMS model embodies the method for predicting the power generation by monitoring and analyzing the climatic data and controling the efficient power distribution between the renewable energy and the existing power. The ultimate goal of this paper is to provide the technological basis for achieving zero-energy house.
