This study demonstrates the association between total sleep duration of adolescents, and its effects on their physical and mental health. Chi-square test and the multiple logistic regression model were applied to analyze the data collected in 2018 by the Korean Youth Health Behavior Survey (n = 52,928), conducted by the Korea Centers for Disease Control & Prevention. Our analysis indicates increased suicidal ideation with insufficient total sleep duration as per the recommended amount and grade (OR: 1.17, 95% CI: 1.06-1.29, p-value: 0.00]. Especially, insufficient sleep among adolescent girls significantly increases the risk of suicidal thoughts (OR: 1.22, 95% CI: 1.06-1.41, p-value: 0.01). Sufficient sleep showed reduced risk of suicidal ideation among boys (OR: 0.83, 95% CI: 0.71-0.96, p-value: 0.02). We propose that to reduce the risk of suicide among teenagers, policy considerations are required to ensure sufficient sleep.

Purpose: Many studies have addressed a psychiatric analysis of self-injury patients who have self-injurious behavior and who have attempted suicide. Few studies on the injury characteristics of self-injury related trauma patients have been conducted. We analyzed the injury characteristics of self-injury patients. Methods: A retrospective review of the medical records extracted from the injury surveillance system of Wonju Christian Hospital for the period from August 2006 to February 2008 was conducted. Of the 121 cases extracted, 103 were included in this study. We analyzed the sex ratio, age group, place of injury, injury mechanism, location of injury, management results, injury severity, and relation with drinking. Results: One hundred three cases were included (sex ratio: 1.06), and the mean age was $33.9{\pm}14.2$ years old. Fifty-six patients (54.4%) were discharged from the emergency department (ED) on the day of injury after primary care, and 9 patients (8.7%) were discharged, because they refused treatment. Seven patients (6.8%) died. Of these, 4 patients (3.9%) died after attempted cardio-pulmonary resuscitation in the ED, 1 patient (1%) was dead on arrival, and 2 patients (1.9%) died after admission. Sixteen patients (15.5%) were admitted to the hospital, including 2 patients (1.9%) needing emergency surgery. Sixteen patients (15.5%) were transferred to other hospitals. Sixty-one cases (59.2%) involved drinking, and 31 (30.1%) did not; for 11 cases (10.7%), the involvement of drinking was unknown. The mean revised trauma score (RTS) was $11.26{\pm}2.52$, and 88 cases (85.4%) hat a RTS of 12. The mean injury severity score (ISS) was $5.80{\pm}14.56$, and 9 (8.7%) severely injured patients had scores of more than 15. Conclusion: Most self-injuries were mild traumas related to drinking and occurred at a young age. Most cases were not so severe, and the patients were discharged from the ED, but some patients needed hospitalization. Other patients had injuries so severe that they died.

The purpose of this study was to investigate the influences of adolescents on self-rated health and happiness, physical activity, and mental health according to time of smartphone use. The researcher used raw data from the Korea youth risk-behavior web-based survey(2017). A total of 64,991 adolescents were enrolled and 54,603 were analyzed in logistic regression analysis. The researcher set gender, self-rated health and happiness, physical activity, and mental health as independent variables and performed logistic regression analysis with smartphone overuse time as dependent variables. As a result, the female had a smartphone overuse of 1.49 to 1.67 times higher than male. Subjectively healthy people were 1.2 to 1.35 times more likely to use smartphones than those who did not(p<.001). People with higher physical activity were higher by 1.17 to 1.18 times than people without physical activity(p<.001). Subjective happiness did not predict smartphone usage(p>.05). People with subjective stress were higher 1.13 to 1.22 times than people without stress, and person with sadness and despair and suicide plan, 1.37 to 1.54 times, 1.17 to 1.24 times than those who did not(p<.001). Depression tended to become more serious as smartphone use increased. These investigation suggest that the self-rated health, physical activity, and mental health excluding self-rated happiness are related to overuse of smartphone.

Purpose: This study is an integrated literature review to analyze health problems and social determinants of multicultural adolescents in South Korea. Methods: An integrative review was conducted according to Whittemore & Knafl's guideline. An electronic search that included publications from 2018 to 2020 in the PubMed, EMBASE, Cochrane Library, CINAHL, RISS, and KISS databases was conducted. Of a total of 67 records that were identified, 13 finally met full inclusion criteria. Text network analysis was also conducted to identify keywords network trends using NetMiner program. Results: The health problems of multicultural adolescents were classified into mental health (depression, anxiety, suicide and acculturative stress) and health risk behaviors (smoking, risky drinking, smartphone dependence and sexual behavior). As social determinants affecting the health of multicultural adolescents, the biological factors such as gender, age, and visible minority, and the psychological factors such as acculturative stress, self-esteem, family support, and ego-resiliency were identified. The sociocultural factors were identified as family economic status, residential area, parental education level, and parents' country of birth. As a result of text network analysis, a total of 41 words were identified. Conclusion: Based on these results, mental health and health risk behaviors should be considered as interventions for health promotion of multicultural adolescents. Our findings suggest that further research should be conducted to broaden the scope of health determinants to account for the effects of the physical environment and health care system.

Depression has a negative impact on social functioning due to its high prevalence and increased suicide rate, and is a disease with a high economic burden. Depression is related to diverse brain-related phenomena, such as neuroinflammation, synaptic dysfunction, and cognitive deficit. As antidepressant drugs used in clinical trials have shown poor therapeutic effects, antidepressant drugs that show rapid efficacy urgently need to be developed. Although studies on various genes, proteins, and signaling pathways related to depression have been conducted, the pathogenesis of depression has not been clearly elucidated. Sirtuin 1 is a nicotinamide-adenine dinucleotide- (NAD+-) dependent histone deacetylase and is involved in cell differentiation, apoptosis, autophagy, and cancer metabolism. Recent genetic studies found that sirtuin 1 is a potential target gene for depression. In addition, preclinical studies reported that sirtuin 1 signaling affects depression-like behavior. In this review, we attempt to present up-to-date knowledge of depression and sirtuin 1. We describe the various roles of sirtuin 1 in the regulation of glial activation, circadian rhythm, neurogenesis, and cognitive function and the effects of its expression on depression. Further, we discuss the effect of sirtuin 1 on the impairment of neural plasticity, one of the key mechanisms of depression, and the associated mechanisms of sirtuin 1.

Mobbing is going the rounds through a society rapidly and Military is not exception. Because mobbing of military is expressed not only psychology exclusion that is mobbing pattern of adult society but also sometimes psychologic and physical mobbing, is possible to join serious military discipline like a suicide and outrageous behavior. Specially military try to protect occurrence of victims that is public service through various rules and management plan but victims is going on happen. It means importance of grasp not only current mobbing victims but also potential mobbing victims better than preparation of various rules and management plans. Therefore this paper extracts seven factors and fifty attributes that are related to this matter mobbing. Next, by using Gunwoo's Social Network Service that is made for oneself and expressing extracting factors as '1' if they are related me or not '0'. And apply similarity function(Dice's coefficient) to attributes summation included in factors to calculate similarity between the users. Third, calculate optimizing weight choosing factors included attributes by applying neural network algorithm of SPSS Clementine and propose Mobbing Value(MV) Algorithm through this total summation. Finally through this algorithm which will contribute to efficient personnel management, we can grasp mobbing victims and tentative mobbing victims.

In this study, in order to understand the social psychological characteristics of college male students majoring in beauty, PAI tests were conducted on 163 university students located in Gyeonggi-do and Chungnambuk area in 2020. First, when comparing the average scales of men who majored in beauty and men who majored in general, the major male students of beauty showed an overall high clinically recognized type compared to students who majored in beauty, and a negative impression on a valid scale (NIM) considered treatment for physical complaints (SOM), depression (DEP) and drinking problems (ALC) on a clinical scale, and a significant difference was shown on a suicide idea (SUI) scale. Secondly, in order to navigate the PAI scale that significantly predicts beauty major male students, a stepwise regression analysis was performed using 15 significant scales as search factors in comparison between beauty major male and general major male students. As a result, physical complaints (SOM) and depression (DEP) scales were extracted, which became a factor that can predict male students in beauty major. Therefore, it can be understood that the male students in the beauty major have behavior patterns that are more obsessed with and more impulsive to physical problems than the male majors. These results will provide a lot of suggestions for the selection of future male students in beauty major, selection, management, education, consultation materials, and selection of occupations after graduation.

This article is the reserch on actual condition of crime of arson which occurs in Korea and its countermeasures. The the presented problem in this article are that (1) we have generally very low rate concern about the crime of arson contrary to realistic problems of rapid increase of crime of arson (2) as such criminal motives became so diverse as to the economic or criminal purpose unlike characteristic and mental deficiency of old days, and to countermeasure these problems effectively it presentation the necessity of systemantic research. Based on analysis of reality of arson, the tendency of this arson in Korea in the ratio of increase is said to be higher than those in violence crime or general fire rate. and further its rate is far more greater than those of the U.S.A. and Japan. Arson is considered to be a method of using fire as crime and in case of presently residence to be the abject, it is a public offense crime which aqccompany fatality in human life. This is the well It now fact to all of us. And further in order to presentation to the crime of arson, strictness of criminal law (criminal law No, 164 and 169, and fire protection law No. 110 and 111) and classification of arsonist as felony are institutionary reinforced to punish with certainty of possibility, Therefore, as tendency of arson has been increased compared to other nations, it is necessary to supplement strategical policy to bring out overall concerns of the seriousness of risk and damage of arson, which have been resulted from the lack of understanding. In characteristics analysis of crime of arson, (1) It is now reveald that, in the past such crime rate appeared far more within the boundary of town or city areas in the past, presently increased rate of arsons in rural areas are far more than in the town or small city areas, thereby showing characteristics of crime of arson extending nation wide. (2) general timetable of arson shows that night more than day time rate, and reveald that is trait behavior in secrecy.(3) arsonists are usually arrested at site or by victim or report of third person(82,9%).Investigation activities or self surrenders rate only 11.2%. The time span of arrest is normally the same day of arson and at times it takes more than one year to arrest. This reveals its necessity to prepare for long period of time for arrest, (4) age rate of arson is in their thirties mostly as compared to homicide, robbery and adultery, and considerable numbers of arsons are in old age of over fifties. It reveals age rate is increased (5) Over half of the arsonists are below the junior high school (6) the rate of convicts by thier records is based on first offenders primarily and secondly more than 4 time convicts. This apparently shows necessity of effective correctional education policy for their social assimilation together with re-investigation of human education at the primary and secondary education system in thier life. The examples of motivation for arosnits, such as personal animosity, fury, monetary swindle, luscious purpose and other aims of destroying of proof, and other social resistance, violence including ways of threatening, beside the motives of individual defects, are diverse and arsonic suicide and specifically suicidal accompany together keenly manifested. When we take this fact with the criminal theory, it really reveals arsons of crime are increasing and its casualities are serious and a point as a way of suicide is the anomie theory of Durkheim and comensurate with the theory of that of Merton, Specifically in the arson of industrial complex, it is revealed that one with revolutionary motive or revolting motive would do the arsonic act. For the policy of prevention of arsons, professional research work in organizational cooperation for preventive activities is conducted in municipal or city wise functions in the name of Parson Taskforces and beside a variety of research institutes in federal government have been operating effectively to countermeasure in many fields of research. Franch and Sweden beside the U.S. set up a overall operation of fire prevention research funtions and have obtained very successful result. Japan also put their research likewise for countermeasure. In this research as a way of preventive fire policy, first, it is necessary to accomodate the legal preventitive activities for fire prevention in judicial side and as an administrative side, (1) precise statistic management of crime of arson (2) establishment of professional research functions or a corporate (3) improvement of system for cooperative structural team for investigation of fires and menpower organization of professional members. Secondly, social mentality in individual prospect, recognition of fires by arson and youth education of such effect, educational program for development and practical promotion. Thirdly, in view of environmental side, the ways of actual performance by programming with the establishment of cooperative advancement in local social function elements with administrative office, habitants, school facilities and newspapers measures (2) establishment of personal protection where weak menpowers are displayed in special fire prevention measures. These measures are presented for prevention of crime of arson. The control of crime and prevention shall be prepared as a means of self defence by the principle of self responsibility Specifically arsonists usually aims at the comparatively weak control of fire prevention is prevalent and it is therefore necessary to prepare individual facilities with their spontaneous management of fire prevention instead of public municipal funtures of local geverment. As Clifford L. Karchmer asserted instead of concerns about who would commit arson, what portion of area would be the target of the arson. It is effective to minister spontaveously the fire prevention measure in his facility with the consideration of characteristics of arson. On the other hand, it is necessary for the concerned personnel of local goverment and groups to distribute to the local society in timely manner for new information about the fire prevention, thus contribute to effective result of fire prevention result. In consideration of these factors, it is inevitable to never let coincide with the phemonemon of arsons in similar or mimic features as recognized that these could prevail just an epedemic as a strong imitational attitude. In processing of policy to encounter these problems, it is necessary to place priority of city policy to enhancement of overall concerns toward the definitive essense of crime of arson.

Objectives : The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. Methods : Parents of 946 elementary school students(age $9.54{\pm}1.72$ years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age $13.98{\pm}0.93$ years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. Results : Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). Conclusions : Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.
