Abnormal illness behavior in patients with somatoform disorders were known formed by their traditional disease concepts and somatization-prone socio-cultural factors. The authors evaluated the characteristics of abnormal illness behavior in patients with somatoform disorders(who had somatization) by using abnormal illness behavior questionnaire. Methods : 29 somatoform disorders(SD) and 57 disease controls were compared by clinical characteristics, severity of pain, state anxiety(by Spielberger's State & Trait Anxiety Inventory), depression(by Beck's Depression Inventory) and level of psychosocial stess(by DSM-III-R). The illness behavior was measured by illness Behavior Questionnaire(IBQ). Results SD group had longer period of somatic symptoms with less severity in pain. The degree of anxiety and depression were higher in SB compared with controls. However, the degree of psychosocial stress was almost same between both groups. In IBQ, SD showed higher scores in general hypochondriasis, disease conviction, and affective disturbance subscales compared to control group. Conclusion: High disease conviction and hypochondriacal nature revealed by IBQ seemed to be a role in making somatization by way of somatic focusing and hypervigilance. And those tended to lead patients visit hospital frequently and report various somatic complaints. Evaluating abnormal illness behavior in somatoform disorders would be not only helpful in understanding the natures of somatoform disorders but also useful differentiating SD with other psychiatric conditions.

This study was conducted to identify the relationship between depression and subjective/objective health status, and to examine predicting factors on depression in the elderly in Korea. This study was a secondary analysis using the data of Korea National Health and Nutrition Examination Survey(VI-1) 2007. A total of 939 data from the subjects ≥60 years who completed health-related survey were used for analysis. Data were analyzed using SAS (version 9.1) PC program. Depression was identified in the 20.3% of the older subjects. Multiple logistic regression analysis showed that women (OR=2.04), senior high school graduation (OR=0.27) and lowermiddle household income (OR=2.83) were significant associating factors(p<0.05). After adjustment for socio-demographic factors, hypertension (OR=1.93) and asthma (OR=3.32) as objective health status, and stress (OR=7.27), limited activity in daily living due to fracture or joint injury (OR=6.59) and poor self-rate health (OR=1.64) as subjective health status were found as factors predicting depression in the elderly(p<0.05). According to the type of health status, the subjects who had chronic disease or perceived poor physical health were 5.94 times more likely to have disposition to depression than the subjects who had no chronic disease or perceived good physical health (p=0.001). These findings suggest that preventive education and intervention focus on preventing and managing chronic diseases such as hypertension, asthma, fracture and joint injury should be needed to decrease depression in the elderly.

Airborne particulate matter (PM) is an environmentally hazardous pollutant that originates from various sources. PM is comprised of solid particles and liquid droplets of diverse composition and size. Hazardous chemical compositions of PM include elemental and organic carbon, organic compounds, biological compounds and metals. Upon acute and chronic PM exposure, toxic contaminants enter and accumulate within physiological systems and prompt cell structure changes accompanied with intracellular endoplasmic reticulum stress, mitochondrial dysfunction, oxidative stress, inflammation, lipid accumulation, and cell cycle arrest. Ultimately, these cellular response leads to the development of key characteristics of aging. In addition, PM internalization enhances autophagy reflux and lysosomal dysfunction, which is involved in cell aging. Previous studies have emphasized a positive association between PM and increased mortality or decreased lifespan, although these are evidenced mostly by observational studies. Direct evidence of the link between PM and aging is still limited. This review evaluates the evidence from not only observational studies but also in vitro and in vivo evidence of PM on aging progression and age-related diseases development. This evidence is based on age-associated cellular changes including endoplasmic reticulum stress, mitochondrial dysfunction, oxidative stress, inflammation, adipose accumulation, autophagy, which strengthen the association between PM exposure and aging. Understanding the underlying cellular responses under PM may allow for the development of new therapeutic targets for PM-induced aging.

Purpose: The purpose of this study was to investigate the disease-related knowledge, stress and quality of life for the patients with varicose veins. Methods: Data were collected via questionnaire from 138 patients with varicose veins in C University Hospital in Korea from November in Korea 2012 to August 2013. Results: Knowledge of the symptoms and diagnosis was the lowest. The scores from patients with disease-related knowledge tended to be low for both subjects over the age of 60 and subjects with low education (less than high school). The score for stress over complications was the highest. The level of stress is higher for women, subjects without spouses, subjects with higher severity of disease and patients who had been taking hormones in the past or are still taking hormones. The disease-related quality of life tended to be lower for women and subjects without spouses. 21% of the variance in quality of life was explained by the level of disease-related stress, disease severity and knowledge. Conclusion: Education and the management of nurses to improve disease-related knowledge for patients with varicose veins is highly recommended. Intervention, by reducing stress, is necessary to improve the quality of life for women, subjects without spouses, and subjects with higher severity of the disease.

To investigate the relationship between dental hygiene students' stress and college life satisfaction, 299 dental students and students in Gyeongnam area studied stress, stress response scale, and university life satisfaction. The results of systematic analysis according to the scale of stress response showed high values in fatigue, frustration, depression and anger. In addition, satisfaction with stress experienced negatively. Stress can give you a negative impact that can lead to serious illness. A systematic analysis using the stress response scale is expected to help reduce stress and improve college life satisfaction when the stress of college life is expected to increase maladjustment and dissatisfaction. We suggest the development and analysis of a stress response tool suitable for dental hygienists.

Technostress- a term coined by Craig Brod- refers to a modern disease of adaptation caused by an inability to cope with new technologies. Stress is a person's adaptive response to a stimulus that places excessive psychological or physical demands on that person. In a similar vein, technostress can affect a variety of side effect such as low work productivity and resistance against new technology. The purpose of this study is thus to investigate of differences of technostressors using demographic informations such as gender, age, computer use skill, and industrial types. To do this, we conducted independence t-test and analysis of variance. We found that demographic characteristics can affect the differences of technostressors. Conclusions and implications are discussed in the last section of this paper.

Purpose: This study examined the effects of Sargassum horneri extracts on palmitic acid (PA)-induced endoplasmic reticulum (ER) stress in HepG2 cells. Methods: HepG2 cells were treated with varying concentrations of S. horneri extract or PA, and the cell viability was measured by water soluble tetrazolium salts analysis. The effective induction of ER stress and the effects of S. horneri were investigated through an examination of the ER stress-related genes, such as activating transcription factor 4 (ATF4), X-box binding protein (XBP1s), C/EBP homologous protein (CHOP), and 78-kDa glucose-regulated protein (GRP78) by quantitative reverse transcription polymerase chain reaction. The expression and activation levels of unfolded protein response (UPR) associated proteins, such as inositol-requiring enzyme-1α (IRE1α), eukaryotic translation initiation factor 2 alpha submit (eIF2α), and CHOP were examined by western blot analysis. Results: The treatment with PA increased the expression of UPR associated genes significantly and induced ER stress in a 12-hour treatment. Subsequent treatment with S. horneri reduced mRNA expression of ATF4, GRP78, and XBP1s. In addition, the protein levels of phosphate (p)-IRE1α, p-elF2α, and CHOP were also reduced by a treatment with S. horneri. An analysis of sirtuin (SIRT) mRNA expression in the S. horneri and PA-treated HepG2 cells showed that S. horneri increased the levels of SIRT2, SIRT6, and SIRT7, which indicates a possible role in reducing the expression of ER stress-related genes. Conclusion: These data indicate that S. horneri can exert an inhibitory effect on ER stress caused by PA and highlight its potential as an agent for managing various ER stress-related diseases.

양계산업이 전업화 규모화되면서 산업의 전문화가 빠르게 진행되고 있다. 채란계 중추산업도 과거 자가육성에서 전문 중추육성으로 바뀌는 추세를 보이면서 중추업이 하나의 산업으로 자리 잡아 오고 있다. 최근에는 대형 농장들이 중추농장을 직접 운영하면서 중추전문 농장들의 비중이 상대적으로 줄어들고 있지만, 전체 숫자 면에서는 여전히 증가하는 추세를 보인다. 이에 발맞추어 중추장에서 육성장으로 닭을 운반하는 업체들도 하나둘 생겨나기 시작하였다. 닭들이 스트레스를 받지 않고 위생적으로 중추장에서 성계사로 이동하느냐 하는 것은 생산성과 직결되기 때문에 매우 중요한 사항으로 대두되고 있다. 특히, 계란 살충제 검출 파동과 관련하여 질병의 매개체인 닭진드기가 닭을 이동하면서 농장으로 유입될 가능성도 제기되면서 위생적으로 닭을 이동하는 것이 더욱 중요해졌다.
