Detecting and assessing human-related risks is critical to improve the on-site safety condition and reduce the loss in lives, time and budget for construction industry. Recent research in neural science and psychology suggest inattentional blindness that caused by overload in working memory is the major cause of unexpected human related accidents. Due to the limitation of human mental workload, laborers are vulnerable to unexpected hazards while focusing on complicated and dangerous construction tasks. Therefore, detecting the risk perception abilities of workers could help to identify vulnerable individuals and reduce unexpected injuries. However, there are no available measurement approaches or devices capable of monitoring construction workers' mental conditions. The research proposed in this paper aims to develop such a measurement framework to evaluate hazards through monitoring electroencephalogram of labors. The research team developed a wearable safety monitoring helmet, which can collect the brain waves of users for analysis. A bispectrum approach has been developed in this paper to enrich the data source and improve accuracy.

Cerebral palsy is one of the most serious forms of disorders of the psychophysical development of children, which manifests itself in disturbances of motor functions, which are often combined with speech disorders, other complications of the formation of higher mental functions, and often with a decrease in intelligence. The article will discuss the speech disorder in children with cerebral palsy. Emphasis is placed on some important aspects, which should bear in mind, investigating the problem of specifics of speech development of children with cerebral palsy. In particular at the heart of speech disorders in the cerebral palsy is not only damage to certain structures of the brain, but also the later formation or underdevelopment of those parts of the cerebral cortex, which are of major importance in linguistic and mental activity. This is an ontogenetically young region of the cerebral cortex, which is most rapidly developing after birth (premotor, frontal, temmono-temporal). It is important to take into account, that children with cerebral palsy have disturbances of phonemic perception. Often, children do not distinguish between hearing sounds, cannot repeat component rows, allocate sounds in words. At dysarthria, there are violations of pronunciation of vowel and consonant sounds, tempo of speech, modulation of voice, breathing, phonation, as well as asynchronous breathing, alignment and articulation. As a result, we identified the main features and specifics of the speech development of children with cerebral palsy and described the conditions necessary for the full development of language. Language disturbances in children's cerebral palsy depend on the localization and severity of brain damage. Great importance in the mechanism of speech disorders has a pathology that limits the ability of movement and knowledge of the world.

The purpose of this article is to capture this situation within the changes that take place due to it, inside the Greek society where there is a great need for professional social workers who are able to work targeted and effectively with foreigners, both children and adults, who have or develop mental health problems for the very first time. Over the recent decades the increasing number of migration flows has exerted and continues to exert great pressure on the health system and on the welfare structures of Greece. The bases for the development of a rudimentary reception and integration system that still is in progress have been delayed, while there has been no happy medium, between the enormous pressure that foreigner users of this system put on, and the humanitarian obligation of a well-governed state towards all residents of the country. Straight through everyday clinical practice in the field of intercultural work, social work has the knowledge and techniques for a total management of emerging problems and at the same time provides a value system with an ethical background which approaches refugees and migrants in order to provide quality services, mostly to users of mental health services.

An electroencephalogram (EEG)-connectome processor to monitor and diagnose mental health is proposed. From 19-channel EEG signals, the proposed processor determines whether the mental state is healthy or unhealthy by extracting significant features from EEG signals and classifying them. Connectome approach is adopted for the best diagnosis accuracy, and synchronization likelihood (SL) is chosen as the connectome feature. Before computing SL, reconstruction optimizer (ReOpt) block compensates some parameters, resulting in improved accuracy. During SL calculation, a sparse matrix inscription (SMI) scheme is proposed to reduce the memory size to 1/24. From the calculated SL information, a small world feature extractor (SWFE) reduces the memory size to 1/29. Finally, using SLs or small word features, radial basis function (RBF) kernel-based support vector machine (SVM) diagnoses user's mental health condition. For RBF kernels, look-up-tables (LUTs) are used to replace the floating-point operations, decreasing the required operation by 54%. Consequently, The EEG-connectome processor improves the diagnosis accuracy from 89% to 95% in Alzheimer's disease case. The proposed processor occupies $3.8mm^2$ and consumes 1.71 mW with $0.18{\mu}m$ CMOS technology.

Background: Childbirth represents a significant transition for women, with physical and psychological sequelae. Reentry to the workplace during the postpartum period is understudied, with implications for maternal well-being and job-related outcomes. This study's aim was to examine selected pregnancy, childbirth, and return-to-work correlates of overall self-rated health within the first month of work reentry after maternity leave. Methods: Between December 2016 and January 2017, we surveyed women employed at a large, public Midwestern university who had given birth in the past five years (N = 249) to examine self-rated overall health in the first month of work reentry. Using ordinal logistic regression, we examined whether physical or psychological health problems during pregnancy, childbirth complications, length of maternity leave, and depression and anxiety at work reentry were related to overall health. Results: Women who experienced depression (odds ratio [OR] = 0.096 [95% confidence interval {CI} = 0.019 to 0.483, p = 0.004]) and anxiety (OR = 0.164, [95% CI = 0.042 to 0.635, p = 0.009]) nearly every day reported worse health at work reentry than those with no symptoms. Controlling for demographics and mental health, women who experienced medical problems during pregnancy (OR = 0.540 [95% CI = 0.311 to .935, p = 0.028]) were more likely to report poor health, while taking a longer maternity leave (OR = 14.552 [95% CI = 4.934 to 42.918, p < 0.001]) was associated with reporting better health at work reentry. Conclusion: Women who experience medical complications during pregnancy, return to the workplace too soon after birth, and experience mental health symptoms are vulnerable physically as they return to work.

Purpose: The purpose of this study was to identify the prevalence of cognitive impairment, behavioral problems, and the state of mental health for elderly Korean people who have been institutionalized. Methods: A cross-sectional, nationwide survey was performed using an anonymous questionnaire. The participants in this study were 2,521 institutionalized elderly Korean people. A proportional stratified random sampling method was employed. Results: 1) Elders admitted to subacute hospitals and long term care (LTC) facilities showed a higher level of cognitive impairment compared to elders admitted to acute care hospitals. 2) Elders confined in LTC facilities showed a higher level of behavioral problems compared to elders in acute or subacute hospitals. 3) Elders admitted to subacute hospitals and LTC facilities showed more serious mental health problems, such as depression or suicidal ideation, compared to elders in acute care hospitals. Conclusion: The results of this study indicate that the severity of cognitive-behavioral or mental health problems do not match well with type of care setting. Therefore, health personnel working with elderly people should be provided guidance on detection and management of cognitive-behavioral and mental health problems. The necessity of a decision support system for eligibility and placement in long-term care is also discussed.

In Oriental medicine, Five Mental is a concept for understanding of man's mental structure. Spirit and body is inseparable relation in Oriental Medicine. Function of spirit and body is regarded as one in Oriental Medical physiology. Spirit is the essence of a function which an organism reveal, and it is regarded in the same with life. For this reason, identification spirit with life is special feature of Oriental Medicine. In Confucianism, Li(理) refers to nature's discipline, which everything under the sun shares. It is similar to the concept of Shin(神) in a broad sense and Sung(性) is similar to that of Shin(神) in a narrow sense. Confucianism's principle is similar to Oriental medicine's, in that they classify Sung(性) into Gi-Jil-Ji-Sung(氣質之性) and Bon-Yeon-Ji-Sung(本然之性), that Sung(性) acts upon man differently according to his disposition, and that materials have an effect on Shin(神)'s action. According to mind's action, there are Human mind(人心) and Moral mind(道心). Human mind(人心) is defined as a mental action of higher degree and Moral mind(道心) is conceived as a mental action related to body. It is similar to Oriental medicine's principle in which Shin(神) is classified into Hun(魂) and Beak(魄) according to its action. Yi(意) is self-control and application, and Zhi(志) is a conscious state in which basic acts towards the object are fixed regularly. Those are similar to the concepts of Oriental medicine.
