This researched is an investigation about the youths runaways street life experienced, the crimes committed through the influenced living in the street by looking into the effectiveness of the youth welfare and make an observation of their direction. The survey was conducted on young people who met in the youth shelter and outreach program, and finally analyzed 259 copies. The results of the study are as follows. First, When comparing the ages of the runaway youths if not properly given a support, services and prevention after running away from home, these youth will live their life in the street until their adolescents. Second, Runaway youth shelter has been providing the needs of those runaway youth who came in the shelter. However, it needs necessary new policy and services that will augment the support in solving problems of the youths when they visit youth shelter to ask for help and support. Third, It can be seen that the flight behavior after the street life is increased. They are in a situation where they have no choice but to join the juveniles for street life. Finally, Street life Youth self-reliance, support for living expenses, housing facilities, job opportunities, technical and job skill training were highly desired by the youths. Eventually, the intervention of youth living in street life requires a multifaceted support such as housing, labor, education, and welfare.

In general, a reinforced concrete slabs are known to have a high fire resistance performance due to thermal properties of concrete materials. However, according to previous research, the thermal behavior of voided slabs is reported to be different from that of conventional RC solid slabs, and the differences seem to be caused by the air layer formed inside the voided slab. Therefore, it is difficult to estimate the temperature distribution of the voided slab under fire by using the existing methods that do not take into account the air layer inside the voided slab. In this study, a numerical analysis model was proposed to estimate the temperature distribution of voided slabs under fire, and evaluated. Heat transfer of slabs under fire is generally caused by conduction, convection and radiation, and time-dependent temperature changes of slab can be determined considering these phenomena. This study proposed a numerical method to estimate the temperature distribution of voided slabs under fire based on a finite difference method in which a cross-section of the slab is divided into a number of layers. This method is also developed to allow consideration of heat transfer through convection and radiation in air layer inside of slabs. In addition, the proposed model was also validated by comparison with the experimental results, and the results showed that the proposed model appropriately predicts the temperature distribution of voided slabs under fire.

Rapid economic development has changed the dietary habits and patterns. Especially, western style diet has increased the risk of type 2 diabetes (T2DM) in Korea. To provide more specific and appropriate diet guideline for the prevention and for the treatment of T2DM, the investigation on the characteristics of diebetic patients related to the diet needs to be done. In this study, we therefore analyzed eating behaviors, dietary attitudes, and intake of food and nutrients of normal subjects (control, n=26) and diabetic patients (case, n=18) diagnosed T2DM within one year in Daegu Gyeongbuk area. Body mass index of the patients were significantly higher than the control (p<0.05). Overeating, high fried food and low whole grain intake were revealed as risk factors for T2DM. From the food frequency questionnaire analysis, salty foods such as fermented soybean paste (Doenjang) and watery Kimch intake were associated with T2DM. Intake of vegetable lipid, ${\beta}$-carotene, calcium, copper, and vitamin K were also shown to be associated with T2DM. Taken together, these findings suggest that maintaining ideal body weight and intake the foods with low salt, fat, and refined grain in appropriate amount may help to prevent and to manage T2DM.

This research was conducted to compare the rhythm reproduction abilities between older adults with and without mild cognitive impairment (MCI) and analyze the abilities depending on the rhythm idiom. Participants between 60-85 years of age were recruited from senior community centers, dementia prevention centers, and senior welfare centers. A total of 57 participants were included in this study: 27 diagnosed with MCI and 30 healthy older adults (HOA). The experiment was conducted individually in a private room in which a participant was given random binary time rhythm idioms and instructed to reproduce the rhythmic idioms with finger tapping. Each participant's beat production was recorded with the Beat Processing Device (BPD) for iPad. BPD calculated rhythm reproduction as measured through rhythm ratio and error among beats. Results showed marginal differences between the two groups in terms of mean scores of rhythm reproduction abilities. In terms of the rhythm ratio among beats, both groups' highest rhythm reproduction rate was for <♩ ♩>, and their lowest reproduction rate was for <♩. ♪>. In conclusion, there was no significant difference in rhythm reproduction ability between the HOA and MCI groups. However, the study found an interesting result related to performance level of rhythmic idioms. This result provides therapeutic insight for formulating rhythm tasks for older adults.

This study investigated changes in the youth smoking rate and smoking cessation rates before and after a cigarette price increase in 2015. Specifically, the changes in smoking rate, smoking cessation attempt rate, selection rate and amount of smoking were investigated using primary data pertaining to Korean Youth Risk Behavior obtained from a web-based survey of youth general characteristics, mental health, subjective grade, drinking and smoking related characteristics before and after a cigarette price increase. To accomplish this, 800 middle school and high school students in 9th (2013), 10th (2014), 11th (2015) were surveyed. The current youth smoking rate was slightly decreased from 9.7% in 2013 to 9.2% in 2014, while the smoking rate in 2015 decreased significantly by 15.2% after the cigarette price increased to 7.8%. These results confirmed that increasing cigarette price is very effective at decreasing youth smoking rate, providing motivation to stop smoking and preventing smoking. The prevention of smoking and inducement to stop smoking during adolescence is very important because the majority of teenage smokers continue smoking into their adulthood. In addition to expanding a completely non-smoking area and a comprehensive ban on tobacco advertising, promotion and sponsorship should be urgently sought, and the effect can be maximized when the WHO FCTC faithfully implements the already-founded treaty.

M&S techniques are widely used as scientific means to systematically develop response plans to chemical and biological (CB) hazards. However, while the theoretical area of hazard dispersion modeling has achieved remarkable practical results, the operational analysis area to simulate CB hazard response plans is still in an early stage. This paper presents a model to simulate CB hazard response plans such as detection, protection, and decontamination. First, we present a possible way to display high-fidelity hazard dispersion in a combat simulation model, taking into account weather and terrain conditions. We then develop an improved vulnerability model of the combat simulation model, in order to simulate CB damage of combat simulation entities based on other casualty prediction techniques. In addition, we implement tactical behavior task models that simulate CB hazard response plans such as detection, reconnaissance, protection, and decontamination. Finally, we explore its feasibility by analyzing contamination detection effects by distributed CB detectors and decontamination effects according to the size of the {contaminated, decontamination} unit. We expect that the proposed model will be partially utilized in disaster prevention and simulation training area as well as analysis of combat effectiveness analysis of CB protection system and its operational concepts in the military area.

The purpose of this study is to examine the effects of social withdrawal, depression, aggression, negative parenting attitude as parental factors, friendship as school factors, academic helplessness and smartphone dependence, persistence, etc. on adolescent delinquency experiences as perceived personal factors. was carried out to understand. For this study, first year middle school students in the first year of the Korean Children and Youth Panel Survey (KCPYS 2018) were analyzed. As a result of the study, it was found that depression, aggression, social withdrawal as individual factors of adolescents, negative parenting attitude as parent factors, academic helplessness, negative friendships, smartphone dependence, persistence, etc. as school factors influence delinquent behavior of adolescents. In addition, it was found that smartphone dependence and persistence play a partial mediating role in the process of personal factors, parental factors, and school factors affecting adolescents' delinquency experiences. Based on these results, first, we need to break stereotypes about adolescents and understand the accurate understanding of adolescents' delinquent behaviors and what expectations they have. Second, practical education is required for parents and grandparents for consistent parenting attitudes and effective parenting. Third, a positive self-awareness and correct human relationship formation program should be operated in order to improve the friendship among adolescents. Finally, correct smartphone usage and counseling interventions and prevention programs to alleviate impulsivity are needed.

South Korean law strictly prohibits engagement in medical activities by non-medical practitioners. In the country, tattooing is classified as a medical practice, and non-medical practitioners who engage in it are penalized because they are unauthorized to carry out this procedure. In reality, however, people rarely seek tattooing services from medical personnel. Arguing that their freedom of job selection is violated, non-medical personnel who make a living as tattoo artists reject the characterization of the procedure as a form of medical treatment and demand the decriminalization of tattooing by non-medical practitioners. Nevertheless, tattooing can cause health- and hygiene-related dangers when it is not performed by medical professionals because it involves penetration into the skin using needles. Hence, stringent management is necessary for infection prevention. The gap between reality and the law gives rise to the need for proactive thinking about the institutionalization of tattoo practice by non-medical personnel. Policymakers should reflect on the fact that only minimal tattooing services are currently performed by medical staff while also accounting for health and safety. On this basis, this study examined tattoo-related legislation in South Korea to determine whether the procedure corresponds to medical practice and identify ways to solve problems that occur from the perspective of health care. As a response that promotes safety and reflects reality, this research proposed a three-phase approach.

Objectives: This study investigated the determinants of depression in adolescents and young adults. Methods: The present study analyzed data from the 2018 Indonesia Basic Health Survey (Riset Kesehatan Dasar; RISKESDAS). The study subjects were adolescents (15-17 years old) and young adults (18-24 years old). In total, 64 179 subjects were included. Univariable, bivariable, and multivariable logistic regression analyses were performed to determine associations between youths' characteristics, risky behavior, chronic disease, parents' health, and youths' depression. Results: The prevalence of depression was 5.1% in adolescents and 5.6% in young adults. The risk factors for depression in adolescents were being women (adjusted odds ratio [aOR], 3.53; 95% confidence interval [CI], 2.89 to 4.30; p<0.001), an ex-smoker (aOR, 2.99; 95% CI, 2.10 to 4.25; p<0.001), or a current smoker (aOR, 2.60; 95% CI, 1.97 to 3.44; p<0.001); consuming alcohol (aOR, 2.00; 95% CI, 1.33 to 3.01; p=0.001), having a chronic disease (aOR, 2.64; 95% CI, 1.41 to 4.96; p=0.002); maternal depression (aOR, 2.47; 95% CI, 1.97 to 3.09; p<0.001); and paternal depression (aOR, 2.63; 95% CI, 1.98 to 3.50; p<0.001). In young adults, the risk factors were being women (aOR, 2.23; 95% CI, 1.82 to 2.75; p<0.001) or an ex-smoker (aOR, 2.47; 95% CI, 1.67 to 3.67; p<0.001), consuming alcohol (aOR, 2.42; 95% CI, 1.89 to 3.09; p<0.001), maternal depression (aOR, 3.12; 95% CI, 2.54 to 3.84; p<0.001), and paternal depression (aOR, 2.80; 95% CI, 2.17 to 3.63; p<0.001). Conclusions: Being women, smoking, drinking alcohol, having a chronic disease, and having a parent with depression were crucial factors associated with youth depression. Mental health screening, prevention, and treatment should involve collaboration among primary healthcare, schools, universities, professionals, and families.
