This study was designed to identify the extent of incident shock who are in high risk of post traumatic shock stress, and analyze the related factors that affect the extent of incident shock. The subjects are 415 rescue workers from Seoul Metropolitan Fire & Disaster Headquarters, who are in high frequency of fire outbreaks and rescue mobilization. With a reliability of Cronbach's ${\alpha}$=.975, the results show invasion, avoidance, sleep disorder and emotional paralysis, dissociative symptom, hyper arousal as foremost causes respectively. Moreover, the results imply that the extent of incident shock was higher in people with more age or being married. Also, from the occupational perspective, the number of years as fire fighters, as rescue workers, mobilization and experiences at work in proportion to incident shocks has risen exponentially. It is notable that the groups who alleviate stress by consuming liquors had higher extent of incident shock. In conclusion, to deal with groups in high risk, management system and prevention care programs for incident shocks need to be introduced immediately and put into effect.

The long-term behaviors of prestressed concrete cable-stayed bridges are considerably influenced by the time dependant material characteristics such as creep and shrinkage. This study investigated the influences of the change of relative humidity by application of the CEB-FIP model and ACI model, which are generally used in the prediction of long-term behavior of concrete structures. In case of the moment of girder, CEB-FIP model predicted a bigger effect of relative humidity change than the ACI model. Furthermore, the effect was significant. Also, the long-term behaviors between these models were different each other even under the same material condition. Therefore, the prediction of the long-term behavior should be compensated after comparative analysis with the results of material tests of each construction site and between the different models.

Objective : The aim of this study is to examine the characteristics of somatic symptoms in patients with PTSD according to trauma type. Methods : The subjects of this study were 84 patients diagnosed with PTSD according to the DSM-IVTR and CAPS criteria. The subjects ranged in age from 18 to 76 years, and they were recruited from 18 hospitals across the nation. All participants were asked about their trauma history, and they all completed the Davidson Trauma Scale (DTS), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Impact of Event Scale-Revised (IES-R) and Korean-Physical Somatic Symptom Inventory (K-PSI). The items of the K-PSI were categorized into 5 groups according to organ system, and the participants were classified into 6 groups according to trauma type. We compared the results of the social demographical scale, DTS, BDI, STAI, IES-R and each recategorized subscale of the K-PSI among the six groups. Results : There were significant differences between the 6 groups in terms of the Korean-Physical Somatic Symptom Inventory scores for each organ system, except for the cardiopulmonary system, as well as the BDI scores. Post hoc analysis revealed differences between the combat-related trauma group and all other groups but not among any of the other groups. Conclusion : Our result showed that there were significant differences in the somatic symptom scores among the 6 trauma groups. However, patient age and the time elapsed since the traumatic event may have hada crucial influence on the result of this study.

Objectives : Somatic symptoms after the exposure of psychological trauma frequently developed. However, the somatic symptoms are not covered under the diagnostic criteria of posttraumatic stress disorder(PTSD) in detail, although they are often associated with social and occupational functioning and patient-doctor relationships. The aim of this article is to highlight the potential mechanisms, the common manifestations, and the treatment of the somatic symptoms. Methods : This article studied the somatic symptoms searched using academic search engines like PubMed, Scopus, Google Scholar, KoreaMed and KISS from the earliest available date of indexing to March 31, 2016. Results : The mechanism of somatic symptoms after the exposure was described as psychological and physiological aspects. Psychological mechanism consisted of psychodynamic theory, cognitive behavioral theory, and others. Physiological mechanism involved changes in neuroendocrine and immune system, autonomic nervous system and central nervous system. Somatization associated with psychological trauma manifested various health conditions on head and neck, chest, abdominal, musculoskeletal, and dermatological and immune system. Few studies described the standardization of treatment for the somatic symptoms. Conclusions : Clinicians and disaster behavioral health providers should think of the accompanying somatic symptoms during intervention of psychological trauma and PTSD. Further studies are needed on the somatic symptoms seen in psychological trauma and PTSD.

This study discussed the trends and characteristics of mental health services in the public libraries of North America. To accomplish this, this study collected its data through literature surveys, observations and interviews with librarians within the Vancouver public library system. The results show that there were many cases in which patrons asked public libraries for information on their mental health problems and the public libraries helped the patrons cope with their problems. The public libraries' assistance programs for national tragedies and natural disasters were temporary services. On the other hand, public libraries were continuously advising and guiding patrons dealing with emotional and psychological problems through the readers' advisory and information services. Specifically, public libraries were actively assisting various sensitive issues that are generated in the development of children and youths(for example, adoption, divorce and separation, remarriage, family, friendship, disabilities, death, self-esteem, emotions, bulling, violence, abuse, suicide, illness, addiction, sexual health, youth pregnancy and so on). The key role of librarians under these circumstances was to guide and recommend appropriate books and professional institutions that help solve the problems.

The purpose of this paper is to verify if safety managers must bear stress from additional tasks whenmanaging smart safety technology applications on construction sites. We conducted a survey of 133 safety managers who had experienced managing both safety management and smart safety technology applications at construction sites, and used the SPSS Statistics 25 and AMOS 22 programs to analyze the survey's logicality and the data that we collected. We found that the work burden caused by assuming additional tasks to manage smart safety technology applications affected the stress that safety managers experience when working at construction sites. The stress caused by an increased work burden led construction site safety managers to feel dissatisfied with their jobs. This finding indicates that both on the original job and on additional tasks are entirely mediated. Based on this finding, I suggest that the South Korean government should establish smart safety technology applications, thus reducing the work burden and increasing the job satisfaction for construction site safety managers.

As part of the digital era, a digital twin that simulates the weak part of a product by performing a stress test that reduces the lifespan of some expensive equipment that cannot be done in reality by accurately moving the real world to virtual reality is being actively used in the manufacturing industry. Due to the development of IoT, the digital twin, which accurately collects data collected from the real world and makes it the same in the virtual space, is mutually beneficial through accurate prediction of urban life problems such as traffic, disaster, housing, quarantine, energy, environment, and aging. Based on its action, it is positioned as a necessary tool for smart city construction. Although digital twin is widely applied to the manufacturing field, this study proposes a smart city model suitable for the 4th industrial revolution era by using it to smart cities and increasing citizens' safety, welfare, and convenience through the proposed model. In addition, when a digital twin is applied to a smart city, it is expected that more accurate prediction and analysis will be possible by real-time synchronization between the real and virtual by maintaining realism and immediacy through real-time interaction.

Intake ratio from river constitutes about 31% (8/26) that beings to "water stress country" as "Medium ~ High" with China, India, Italy, South Africa, etc. Therefore, the present study on a dam that is the most effective and direct for securing water resources has been performed. First of all, climate change scenarios were investigated and analyzed. RCP 4.5 and 8.5 with 12.5 km grid resolution presented in the IPCC (Intergovernmental Panel on Climate Change) 5th Assessment Report (AR5) were applied to study watershed using SWAT (Soil and Water Assessment Tool) and HEC-ResSim models that carried out co-operation. Based on the results of dam simulation, the reduction effects of floods and droughts were quantitatively presented. The procedures of dam projects of the USA, Japan and Korea were investigated. As a result, there are no estimating quantitative criteria, calculating methods or formulas. In the present study, therefore, indexes for selecting suitable dam site through literature investigation and analyzing dam watersheds were determined, Expert questionnaire for various indexes were performed. Based on the above mentioned investigation and expert questionnaire, a methodology assigning weight using AHP method were proposed. The function of suitable dam (FSDS) site was calibrated and verified for four medium-sized watersheds. Finally, automated model for suitable dam site was developed using FSDS and 'Model builder' of GIS tool.

The purpose of this study is to evaluate the effect of the spread of a new type of coronavirus infection (COVID-19) on the mental state in school-age children and parents focusing on the aspects of sleep disorders and depression. A questionnaire survey was conducted for 123 parents and 108 school-age children who visited Department of Pediatric Dentistry, Kyung Hee University Dental Hospital at Gangdong from April 2, 2020 through April 25, 2020, via the direct writing method. Participants were assessed with Pittsburgh Sleep Quality Index, Generalized Anxiety Disorder (GAD)-7, Center for Epidemiology Scale for Depression. Logistic regressions were used with a level of significance of 5%. The prevalence of GAD, depression, and poor sleep in parents were 34.1%, 17.1% and 44.7%, respectively. The prevalence of GAD in children was 20.4%. Logistic regression showed that stress from Emergency Alert Messages about COVID-19 was associated with GAD and depression in parents. In children, the degree of emotional change after COVID-19 was associated with GAD. This study confirmed that there was a change in the psychological status of children and guardians due to the epidemic of coronavirus disease-2019, and it would be necessary to consider their psychological status during dental treatment.
