In this study, we try to find out and analyze the results of reduced self-esteem and loss using text mining. Physical health is important, of course, but these days, mental health is considered more important. In order for the mind to be healthy, it is important to have self-esteem and self-confidence first. Self-esteem decreases, and if lost, it directly leads to depression. If depression is severe, the worst will lead to self-harm and suicide. However, more and more people are committing suicide these days because both ordinary people and entertainers cannot overcome depression. For this reason, the seriousness of depression and loss of self-esteem are also considered important and become an issue. Therefore, we want to collect data for a certain period of time through Naver, Instagram, and Twitter searches and extract the words of the data to anticipate and analyze the cause of loss of self-esteem, how serious the recent depression is, and what the consequences of loss of self-esteem are.

Objectives : An abrupt economic decline may widen the socioeconomic differences in health between the advantaged and disadvantaged in a society. The aim of this study was to examine whether the South Korean economic crisis of 1997-98 affected the socioeconomic inequality from all-causes and from cause-specific mortality between 1995 and 2001. Methods : Population denominators were obtained from the registration population data, with the number of death (numerators) calculated from raw death certificate data. The indicator used to assess the geographic socioeconomic position was the per capita regional tax revenue. Administrative districts (Si-Gun-Gu) were ranked according to this socioeconomic measure, and divided into equal population size quintiles on the basis of this ranking. The sex- and 5-year age-specific numbers of the population and deaths were used to compute the sex- and age-adjusted mortality rates (via direct standardization method), standardized mortality ratios (via indirect standardization methods) and relative indices of inequality (RII) (via Poisson regression). Results : Geographic inequalities from all-causes of mortality, as measured by RII, did not increase as a result of the economic crisis (from 1998-2001). This was true for both sexes and all age groups. However, the cause-specific analyses showed that socioeconomic inequalities in mortalities from external causes were affected by South Korean economic crisis. For males, the RIIs for mortalities from transport accidents and intentional self-harm increased between 1995 and 2001. For females, the RII for mortality from intentional self-harm increased during the same period. Conclusions : The South Korean economic crisis widened the geographic inequality in mortalities from major external causes. This increased inequality requires social discourse and counter policies with respect to the rising health inequalities in the South Korean society.

Due to the awareness of their rights for medical liability and the advancement of legal principles, it becomes also not hard to find those who seek damages against hospitals, doctors and nurses for the suicide committed under the protection of psychiatric institute in Korea these days. Judgements on these kinds of cases are not enough yet, so that it may be too early to try to find principles used in these cases, however it is hardly wrong to read following things from above cases. That is, to gain the case, plaintiffs should show (1) there exists an obligation of "due care"(there is a special relation between patients and hospitals), (2) the duty is violated on the basis of the applicable standard of care, (3) whatever injures or damages are sustained are proximately caused by the breach of duty and (4) the plaintiff suffers compensable damages. To specific, whether a psychiatric institute was liable for wrong death or not depends upon the patients conditions, circumstances and the extent of the danger the patients poses to himself or herself; in short, the foreseeability of self-inflicted harm(the doctor should have or could reasonably have foreseen the patient's suicide and the doctor's negligence actually caused the suicide). In this context if a patient exhibit strong suicidal tendencies, constant observation should be required. Negligence has been found not exist, however, when a patient abruptly and unexpectedly dashes from an attendant and jumps out a window or otherwise attempts to injure himself or herself. And the standard of conduct that is required to meet the obligation of "due care" is based on what the "reasonable practitioner" would do in like circumstances. The standard is not one of excellence or superior practice; it only re quires that the physician exercise that degree of skill and care that would be expected of the average qualified practitioner practicing under like circumstances. Most of these principles have been established at cases of the U.S.A and Japan. In this article you can also find the legal organizations of medical liability and medical contacts on the suicide of patients who have psychiatric diseases under Korean negligence law.

Objectives The Eum-Yang (Yin-Yang in English) temperament was shown to have clinical and structural validity with Sasang Personality Questionnaire (SPQ), however the studies of the association with behavior problems and personality structure in adolescents were not satisfactory. The purpose of this study was to examine the relationships between Eum-Yang temperament and behavior problems in Korean middle school students. Methods 122 first grader of middle school students (68 boys and 54 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and Youth Self Report (YSR). The correlations between SPQ, JTCI, and YSR subscales were investigated. And, also the differences between SPQ, JTCI, and YSR subscales among Yang (high 30% of SPQ total score) and Eum (low 30% of SPQ total score) temperament groups classified with SPQ total score were examined. Results The SPQ total score were correlated with Novelty-Seeking (r=.321) and Reward-Dependence (r=.392) in boys, and with Novelty-Seeking (r=.427) and Harm-Avoidance (r=-.444) in girls. The SPQ total score were not significantly correlated with Body Mass Index, Ponderal Index and YSR total, however significantly correlated with YSR Internalizing problems and Withdrawal/depressed subscale (r=-.242 and r=-.419) in boys and Withdrawal/depressed subscale (r=-.449) in girls. There were significant differences between Eum and Yang groups in Novelty-Seeking, Harm-Avoidance and Withdrawal/depressed as for boys and girls. Conclusions The biopsychological structure of SPQ was confirmed with middle school students. The behavioral (SPQ-B) and emotional (SPQ-E) perspectives of Eum-Yang were found to be protective and risk factors, and also correlated with Externalizing and Internalizing behavior problems, respectively. The biopsychological characteristics of Eum-Yang temperament and its relation with psychopathological symptoms in late-childhood should be carefully analyzed.

The purpose of Electronic warfare is to disturbe, neutralize, attack, and destroy the opponent's electronic warfare weapon system or equipment. Suppression of Enemy Air Defense (SEAD) mission is aimed at incapacitating, destroying, or temporarily deteriorating air defense networks such as enemy surface-to-air missiles (SAMs), which is a representative mission supported by electronic warfare. This paper develops a simulator for analyzing the effectiveness of SEAD missions under electronic warfare support using C++ language based on the DEVS (Discrete Event Systems Specification) model, the usefulness of which has been proved through case analysis with examples. The SEAD mission of the friendly forces is carried out in parallel with SSJ (Self Screening Jamming) electronic warfare under the support of SOJ (Stand Off Jamming) electronic warfare. The mission is assumed to be done after penetrating into the enemy area and firing HARM (High Speed Anti Radiation Missile). SAM response is assumed to comply mission under the degraded performance due to the electronic interference of the friendly SSJ and SOJ. The developed simulator allows various combinations of electronic warfare equipment specifications (parameters) and operational tactics (parameters or algorithms) to be input for the purpose of analysis of the effect of these combinations on the mission effectiveness.

Purpose: The COVID-19 pandemic led to significant changes in the lifestyle patterns of children and affected the patterns of pediatric injuries. This study analyzed the changing patterns of pediatric injury overall and by age groups, based on the datasets before and during the COVID-19 pandemic. Methods: This study is based on the data of patients who presented with injuries at 23 hospital emergency departments participating in the Emergency Department-based Injury In-depth Surveillance (EDIIS) conducted by the Korea Disease Control and Prevention Agency. The surveillance data was categorized by injury mechanism, location, activity, and severity. We analyzed the injury patterns of pediatric patients aged 0 to 15 years. Subgroup analysis was conducted by age group in children aged 7 to 15 years, 1 to 6 years, and <1 year. Results: When comparing the COVID-19 pandemic period to the pre-COVID-19 period, the total number of pediatric patients with injuries decreased by 38.7%, while the proportions of in-home injuries (57.9% vs. 67.9%), and minor injuries (38.9% vs. 39.7%) increased. In the 7 to 15 years group, bicycle riding injuries (50.9% vs. 65.6%) and personal mobility device injuries (2.4% vs. 4.6%) increased. The 1 to 6 years group also showed an increase in bicycle accident injuries (15.8% vs. 22.4%). In the <1 year group, injuries from falls increased (44.5% vs. 49.9%). Self-harm injuries in the 7 to 15 years group also increased (1.6% vs. 2.8%). Conclusions: During the COVID-19 pandemic period, the overall number of pediatric injuries decreased, while injuries occurring at home and during indoor activities increased. Traffic accidents involving bicycles and personal mobility devices and self-harm injuries increased in the 7 to 15 years group. In the <1 year group, the incidence of falls increased. Medical and societal preparedness is needed so that we might anticipate these changes in the patterns of pediatric injuries during future infectious disease pandemics.

Cerebral palsy, a range of non-progressive syndromes of posture and motor impairment, is a common cause of disability in childhood. Self-injurious behavior(SIB) is deliberate harm to the body without suicidal intend, often involving repetitive actions that cause tissue damage. One of the most common orofacial self-injurious behavior is chewing tongue, lip or oral mucosa. This kind of SIB in children is not common in normal children. High occurrence rates are observered in cases of syndromatic, mentally retarded children, and children with congenital disease. Various methods such as behavior modification, behavior control by drugs, body restraints, application of dental appliance, surgery and extraction of teeth have been suggested to control those self-injurious behavior. Using mouthguard as one of dental applainaces is the most conservative and appropriate method in terms of reducing oral self-injurious habits and protection of tissue. This case report describes a child with cerebral palsy who presented with self-injurious ulceration of lip and buccal mucosa. A modified mouthguard was effective in preventing self-injurious oral trauma in a child with cerebral palsy.

Purpose: This study aimed at exploring relationships among Internet addiction, smoking, and drinking and examining the effect factors on Internet addiction, smoking and drinking. Methods: By using stratified sampling, 1,529 participants representing high school students in the Kangwon province were selected. Data was analyzed by SPSS 12.0. using ${\chi}^2$, Pearson correlation coefficient and multiple regression. Results: One-fifth of the total participants were at the mild or moderate stage of Internet addiction. Regarding smoking, 22.7% of male subjects and 4.5% of female subjects were current smokers. Regarding drinking, the percentages of subjects who drank alcohol once or twice per month were 53.5% of male students and 40.7% of female students. Internet addiction positively correlated with depression, novelty seeking, harm avoidance and reward dependence, Internet addiction negatively correlated with persistence, self-directness, cooperativeness, and self-transcendence. Significant factors affecting Internet addiction were depression, gender, novelty seeking, and self-transcendence. Important factors influencing smoking were drinking, gender, school type, satisfaction with school, novelty seeking, and reward dependence. Significant factors affecting drinking were smoking, novelty seeking, school type and ages. Conclusion: This study shows the necessity of developing and implementing effective intervention programs in order to prevent adolescents from experiencing Internet addiction and health risk behaviors.

Recently, nonsuicidal self-injury (NSSI) has been increasing considerably in school counseling. According to the Youth Counseling and Welfare Development Institute, the number of counseling support for NSSI adolescent in 2018 was more than three times higher than the previous year, and the average time when NSSI behavior first appeared was 12.43 years old. As such, adolesnect NSSI continues to increase in recent years, and the age is also gradually decreasing. Nevertheless, research on the motives and characteristics of NSSI among domestic adolescents is still insufficient. This may be attributed to the difficulty of conducting research because self-injury behavior is secretly performed. However, it is also true that this reality has another limitation in the school field, which urgently requires counseling intervention and prevention of students' mental health problems. In addition, counseling for self-injury in the school scene is the biggest cause of exhaustion for counselors because they are under very great stress to cope with repeated self-harm in the dual role of counselors and teachers in school situations. Therefore, this study examines the causes and characteristics of involuntary self-injury through previous research analysis, and examines various difficulties experienced as a school counselor, as well as the effective intervention method of non suicidal self-injury in school counseling.
