Objective : The aim of this study is to identify the relationship between childhood abuse and affective symptom including resilience in patients with depression or anxiety. Methods : A total 256 outpatients diagnosed with depressive disorder or anxiety disorder according to DSM IV-TR, were evaluated with Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Parent-Child Conflict Tactics Scale (PCCTS), Connor-Davidson Resilience Scale (CD-RISC). Independent t-test, Chi-square analysis and analysis of covariance (ANCOVA) were performed to identify the demographics of patients and the relationship between affective symptoms including resilience and childhood abuse. Results : Among demographic and clinical variables, patients with childhood abuse history were significantly higher rate in patients who were living alone and unemployed. In affective symptoms, patients with childhood abuse history were significant more severe in depressive symptoms, and state anxiety score than patients without history of childhood abuse. Patients with childhood abuse history had higher score for trait anxiety and lower score for resilience than patients who had no history of childhood abuse. Conclusion : These finding suggest that history of childhood abuse might be risk factor on depressive and anxiety symptoms severity. And this might be a predictable factor of poor treatment outcome.

Background Abdominoplasty, with or without liposuction, is among the most frequently performed aesthetic procedures. Its main objective is to improve the body contour by means of excising redundant skin and fat tissue. Although abdominoplasty is considered a safe procedure with high satisfaction rates, intraoperative and postoperative complications can become a challenge for the surgical team. The aim of this article is to offer a synopsis of the most common complications arising after abdominoplasty, along with evidence-based guidelines about how to prevent and treat them. Methods A systematic MEDLINE search strategy was designed using appropriate Medical Subject Headings (MeSH) terms, and references were scanned for further relevant articles. Results According to the published case series, local complications are considerably more common than complications with systemic repercussions. Approximately 10% to 20% of patients suffer a local complication following abdominoplasty, while fewer than 1% suffer a systemic complication. Prevention and management strategies are critically discussed for complications including seroma, haematoma, infection, skin necrosis, suture extrusions, hypertrophic scars, neurological symptoms, umbilical anomalies, deep venous thrombosis and pulmonary thromboembolism, respiratory distress, and death. Conclusions The complications of abdominoplasty vary in severity and in the impact they have on the aesthetic outcomes. Recommendations for prevention and management are based on various levels of evidence, with a risk of observer bias. However, most complications can be treated appropriately following the current standards, with satisfactory results.

A special concern is paid to the risks with which small-sized water resources systems are confronted in supplying water in the far future. Taking the Gwangdong dam reservoir as a case study, the authors seek to understand demand-side and supply-side disturbances of a reservoir, which, respectively, corresponds to effects of water demand changes on the intake amount and those of climate changes on the inflow amount. In result, it is demonstrated that both disturbances in the next 50 years are almost unpredictable. Yet the projection ranges, thought of as relatively reliable information that models offer, reveal that severity and period of water shortage is very likely to change. It is therefore concluded that water resources management requires more rigorous approaches to overcoming high uncertainties. The methods and models for projecting those disturbances are selected, based on practicality and applicability. Nevertheless, they show a large usefulness, especially in dealing with data shortage and reducing the needs for expensive modeling resources.

Pollution flashover of outdoor insulators is a common risk, which affects the safe operation of overhead transmission networks. Early electrical power systems, which feature insulators made from ceramic materials have been used all over the world with good performance. At present, non-ceramic insulators are in common use, as a result of their good electrical as well as mechanical properties. The aim of this paper is to discuss and compare the flashover performance of insulators typically used in power lines, such as, porcelain, ethylene-propylene-diene-monomer (EPDM) rubber, room temperature vulcanized (RTV) and high temperature vulcanized (HTV) coated silicone rubber. The effect of various parameters, including the severity of pollution, ice accumulation, and shade profile, are considered.. From the studies reviewed it was concluded that there is a distinct difference in the flashover voltages of different types of insulators, and the silicone provides the best flashover performance of all insulating materials.

Background: Gradual loss of cytokeratin 13 (CK13) may be linked with the severity of dysplastic changes and transformation to malignancy. In this study we assessed the differential expression of CK13 in normal, hyperplastic, dysplastic and cancerous oral mucosa. Materials and Methods: A total of 93 oral biopsies were collected during the 2011-2014 period. The biopsies were characterized as normal (19), hyperplastic (21), severely dysplastic/carcinoma in situ (16) and invasive oral squamous cell carcinoma (OSCC) (37) after morphological assessment. Formalin fixed paraffin embedded sections were stained with a monoclonal antibody against CK13 using the Envision technique. Immunohistochemically stained slides were then analyzed for CK13 expression. Results: CK13 was consistently and diffusely expressed in all normal and hyperplastic tissue biopsies from oral mucosa. Severely dysplastic/carcinoma in situ biopsies showed complete loss in 50% of cases, while in the remaining 50% expression was very focal and weak. OSCC cases showed complete or near complete loss of CK13 in all cases. Few cases showed weak expression in keratin pearls only. Conclusions: This study validates the utility of CK13 IHC as a useful immunohistochemical marker in routine diagnostic practice to make distinction between non-neoplastic from dysplastic and neoplastic (malignant) oral lesions.

Purpose: This retrospective study was designed to examine the frequency of unplanned extubation, and to identify the related factors of unplanned extubation in medical intensive care unit patients. Methods: Data were collected from medical records of patients who received intubation in a medical intensive care unit. One hundred eighteen patient charts were selected for the study. The Patient Severity Classification Scale and unplanned extubation risk factors were examined. Data were analyzed with descriptive statistics, $x^2$-test, Fisher's exact test and Mann-Whitney U test. Results: The incidence of unplanned extubation was 11 (9.32%) out of 118 patients who had undergone intubation. There were statistically significant differences between the unplanned extubation and work shift ($x^2$=61.52, p=.001), ventilation mode (p=.001), number of days of ventilator application (U=366.00, p=.038) and administration of sedatives (p=.025). Conclusion: Unplanned extubation is affected by the following variables: a) whether a nurse is in night shift, b) whether ventilation is mandatory, c) duration of ventilation use and d) administration of sedatives.

Purpose: This study examined gender differences on Musculoskeletal disease (MSD) medical status, the characteristics of the approved patients in workers, and the factors affected approval. Methods: Claim data for the MSD to the Korea Worker's Compensation & Welfare Services (2011) were employed. The medical status by gender was analyzed using t-test, chi square-test and multivariate logistic regression models. Results: The number of claims for MSD has continuously increased in females but not in males since 2006. The severity measured by the care duration, surgery experience and disability grade has been substantially higher in males than in females. Age, size of company, types of occupation, work duration and the weight of materials handled daily were associated with the approval. When males were considered, the work duration, the weight of materials handled daily and parts of the body were statistically significant predictors of approval in males. In case of female, there were meaningful predictors in types of industry and parts of the body. Conclusion: These findings suggest that gender-specific risk factors of MSD should be measured and the management program for MSD should be developed.
