연구목적 청소년의 고카페인 음료(에너지 드링크) 섭취가 급격히 증가하며 사회적인 이슈가 되고 있지만 정신과적인 영향에 대해서는 아직까지 자세히 밝혀지지 않았다. 본 연구에서는 청소년의 고카페인 음료 섭취와 우울증상, 자살생각, 자살계획 및 자살시도 간의 관계를 알아보고자 하였다. 방 법 2014년 수행된 제 10차 대한민국 청소년건강행태온라인 조사에서 자기기입식 설문을 통해 고카페인 음료섭취 유무 및 섭취 용량, 우울증상, 자살생각, 자살계획, 자살시도 경험을 평가하였다. 수집된 자료를 바탕으로 변인들의 관련성을 알아보기 위해 카이제곱 검정을 시행하였고, 우울증상과 자살생각, 자살계획, 자살시도의 위험요인을 파악하기 위해 나이, 성별, 학업성취도, 가족경제수준을 보정하여 다중 로지스틱 회귀분석을 실시하였다. 결 과 본 연구에서는 총 71,638명의 자료를 분석에 사용하였다. 최근 1주일 동안 고카페인 음료를 섭취한 적이 있는 청소년이 그렇지 않은 경우에 비해 우울증상(p<0.01), 자살생각(p<0.01), 자살계획(p<0.01), 자살시도(p<0.01) 경험이 통계적으로 유의하게 높았으며, 고카페인 음료 섭취 경험은 자살시도(O.R=1.99 ; 95% CI, 1.77-2.22)의 위험요인으로 나타났다. 청소년 카페인 일일 섭취권고량을 초과하는 고용량 섭취군이 저용량 섭취군에 비해 우울증상(p<0.01), 자살생각(p<0.01), 자살계획(p<0.01), 자살시도(p<0.01) 경험이 통계적으로 유의하게 높았으며, 고용량 카페인 섭취가 자살시도(O.R=4.05 ; 95% CI, 3.02-5.43)의 위험요인으로 확인되었다. 결 론 본 연구에서 청소년의 고카페인 음료 섭취는 우울증상, 자살생각, 자살계획, 자살시도 경험의 증가와 유의한 관련성이 있었으며, 일일섭취권고량을 초과하는 고용량 카페인 섭취는 자살 시도의 위험성을 높이는 요인임을 확인하였다. 본 연구의 결과는 고카페인 음료 섭취가 청소년의 심리적, 정신적 어려움과 관련될 수 있어 주의가 필요함을 강조한다. Objectives : Despite the increased popularity of highly caffeinated beverages, there is little research examining psychiatric adverse effects. The purpose of this study was to investigate the relationships among pattern of highly caffeinated beverage intake and depressive symptom, suicidal ideation, suicidal plan, suicidal attempt in Korean adolescents. Methods : The data was obtained from the 2014 Korean Youth's Risk Behavior Web-based Study by Korea Centers for Disease Control & Prevention. All participants conducted web-based questionnaire survey. Chisquare test and multiple logistic regression analysis were performed to determine the association among highly caffeinated beverage intake pattern, depressive symptom, suicidal ideation, suicidal plan and suicidal attempt adjusting for differences in age, gender, academic achievement, socioeconomic status. Results : A total of 71,638 participants were enrolled in this study. Depressive symptom, suicidal ideation, suicidal plan and suicidal attempt were significantly more frequent in the group with presence of highly caffeinated beverage intake within 1 week than in non-drinker group(p<0.01). Highly caffeinated beverage intake was significantly associated with suicidal attempt(OR=1.99 ; 95% CI, 1.77-2.22). In addition, depressive symptom, suicidal ideation, suicidal plan and suicidal attempt were significantly more common in the group with heavy-drinker who exceed recommended daily intake dose of caffeine than in the group with light-drinker(p<0.01). Heavy drinking of caffeinated beverage was significantly associated with suicidal attempt(OR=4.05 ; 95% CI, 3.02-5.43). Conclusions : We found that highly caffeinated beverage intake was related to more frequent depressive symptom, suicidal ideation, plan, attempt in adolescents. Also, caffeine intake which exceed recommended daily intake dose identified the predictor of suicidal attempt. Our result suggested that clinicians need to be aware of the possible psychiatric adverse effects of highly caffeinated beverage in vulnerable population including young adolescents.

Objectives: We aimed to compare the smoking behaviors in adolescents from monocultural and multicultural families and to evaluate the associations between their smoking behavior and number of suicide attempts. Methods: The data used in this study was collected from The Tenth Korea Youth Risk Behavior Web-based Survey. The differences in the sociodemographic characteristics between the adolescents in the multicultural and monocultural families were analyzed through the χ<SUP>2</SUP>-test, and a logistic regression was conducted to evaluate the relationships between the smoking behavior and number of suicide attempts of the adolescents in multicultural families. The process involved an analysis using a complex sample design. Results: There was significant difference in the weighted rates of the current smoking behavior (13.3% vs. 8.4%, p<0.001), experience of violence (6.8% vs. 2.3%, p<0.001), and number of suicide attempts (5.4% vs. 2.7%, p<0.001) between the adolescents from the multicultural and monocultural families. In both groups, the current smoking behavior was associated with the number of suicide attempts (multicultural families OR=6.5, p=0.005; monocultural families OR=1.5, p<0.001). Conclusion: Our results showed that the percentage of current smokers in the adolescents from multicultural families was higher than that in the monocultural families and that current smoking behavior is related to the number of suicide attempts in both groups, after adjustment for age, sex, socioeconomic status, academic achievement, current smoking behavior, depressive mood and experience of violence.

Objectives:Diverse psychiatric symptoms and individual traits comprise risk factors of suicide ideation. The aim of this study was to investigate whether depressive symptoms and stress-related symptoms mediate between impulsivity and suicidal ideation. Methods:A total of 445 participants completed the Barratt Impulsiveness Scale-11-Revised Korean version(KBIS-11), Scale for Suicide ideation(SSI), Center for Epidemiological Studies-Depression Scale(CES-D), and Impact Event Scale-Revised Korean version(IES-R-K) before basic military training. Structural Equation Model(SEM) was used to determine integrated relationship between impulsivity, suicide ideation, depressive symptoms and stress-related symptoms. Results:SEM showed good model fit. The direct effect was 0.107(p<0.05) between impulsivity and suicide ideation; and the indirect effect was 0.199(p<0.01) between impulsivity and suicidal ideation through depressive symptoms and stress-related symptoms. Conclusion:The present study revealed a significant mediating effect between impulsivity and suicidal ideation through depressive symptoms and stress-related symptoms. The findings indicated that comprehensive assessment of impulsivity, depressive symptoms and stress-related symptoms are needed for evaluation of suicidal ideation.

Objectives:The aim of this study was to examine the severity of family relations risk and depressive symptom of marriage immigrant women and investigate risk factors which influence family relations risk. Methods:All participants conducted self-report questionnaire survey including sociodemographic characteristics, Family Relations Problem Symptoms Scale, Patient Health Questionnaire-9(PHQ-9). Spearman correlation analysis was performed to examine the relationship between depressive symptoms and family relations problem symptoms. Also, logistic regression analysis was conducted to identify the risk factors which influence the family relations risk. Results:A total of 350 participants were enrolled in this study. There was a significant positive correlation between depressive symptom score and Family Relations Problem Symptoms Scale score(r=0.33, p<0.01). Obtaining Korean nationality(O.R=3.23, 95% CI=1.04-10.01) and depression(O.R=11.32, 95% CI=1.73-74.21) were significant predictors for increased family relations risk in marriage immigrant women. Conclusion:This study emphasizes the need for institutional support including acquisition of nationality and active management of depressive symptoms to help marriage immigrant women settle in domestic society.

Objectives:This study aimed to investigate the relationship among suicidal ideation, addictive mobile phone use and depressive symptoms in bullies who experienced school violence. Methods:The study subjects consisted of 218 adolescents in The Foundation for Preventing Youth Violence(FPYV) after school violence. The participants conducted self-report questionnaire for addictive mobile phone use, Suicidal Ideation Questionnaire-Junior(SIQ-JR) and Center for Epidemiological Studies Depression scale(CES-D). Pearson correlation, logistic regression and path analysis were performed to evaluate the relationship. Results:67 subjects(30.7%) and 46 subjects(21.1%) of total participants were regarded as having clinically significant depressive symptoms and suicidal ideation. SIQ-JR score were correlated with addictive mobile phone use score (r=0.291, p<0.001) and CES-D score(r=0.567, p<0.001). CES-D score were significant risk factor for suicidal ideation (O.R=1.12, 95% CI= 1.08-1.16). We also found that the depressive symptoms directly related to suicidal ideation(standardized coefficient=0.53, p<0.05) and addictive mobile phone use(standardized coefficient=0.38, p<0.05) in bullies of school violence using the path analysis. Conclusion:The rate of depressive symptoms and suicidal ideation are relatively high and the increased depressive symptoms are associated with addictive mobile phone use in bullies of school violence. There is need to consider bullies as a victim who need appropriate intervention in order to prevent subsequent suicide.

Objective:This study examined the effect of social support on metabolic syndrome (MetS) among elderly population in a city in Korea. Methods:A total of 352 people all over 60 years of age were analyzed from the data of the Korean Longitudinal Study on Cognitive Aging and Dementia. This study was started in 2010 and is in progress till date. We compared the documented diagnoses of MetS and Medical Outcome Study Social Support Survey at the baseline of the study and two years later. Results:315 were normal, 37 were developed after two years among subjects without MetS at baseline. When the level of social support was compared at baseline and then at the time of the reassessment two years later, the level had increased in the normal group and the level had not significantly changed for the MetS group. The findings documented at the two year mark indicate that the higher and stronger the level of social support, the lower the risk of developing MetS (odds ratio=0.053, p=0.040). Conclusion:The elderly with good social support are noted to be at lower risk in developing MetS as opposed to those with poor social support. It is apparent that adequate social support shows reduced prevalence of MetS among the elderly. Methods to identify strategies in improving social support networks are needed to expand public health resources and to better accommodate the community-based care of the elderly.

이 연구에서는 스마트 기기를 활용한 개념 적응적 개별화 학습의 효과를 개념 이해도, 개념 파지, 학업 성취도, 학습 동기, 과학 수업에 대한 즐거움, 스마트 기기를 활용한 수업에 대한 인식 측면에서 조사하였다. 서울시의 한 남녀 공학 중학교 1학년 4개 학급을 통제 집단과 처치 집단으로 배치하고, 7차시 동안 ‘분자의 운동’에 대하여 수업을 실시하였다. 이원 공변량 분석 결과, 처치 집단의 개념 검사, 개념 파지 검사, 학습 동기 검사, 과학 수업에 대한 즐거움 검사의 점수가 통제 집단에 비하여 유의미하게 높았다. 학업 성취도 검사에서는 처치 집단의 점수가 통제 집단보다 높았으나, 그 차이가 통계적으로 유의미하지 않았다. 스마트 기기를 활용한 수업에 대한 학생들의 인식도 긍정적인 것으로 나타났다. In this study, we investigated the effects of individualized learning adapted to students` conceptions using smart devices in science instruction upon students` conceptual understanding, the retention of conception, achievement, learning motivation, enjoyment of science lessons, and perception about individualized learning using smart devices. Four seventh-grade classes at a coed middle school in Seoul were assigned to a control group and a treatment group. Students were taught about molecular motions for seven class periods. Two-way ANCOVA results revealed that the scores of a conception test, the retention of the conception test, a learning motivation test, and an enjoyment of science lessons test for the treatment group were significantly higher than those for the control group. Although the score of the treatment group was higher than that of the control group in the achievement test, the difference was not statistically significant. Students` perceptions about individualized learning using smart devices were also found to be positive.

The productivity and growth pattern of Sargassum confusum (Phaeophyta, Sargassaceae) was investigated in Ohori, east coast of Korea, from March 1983 to April 1984. S. confusum shows an obvious seasonal variation of the growth by passing through the germinative, vegetative, reproductive and decaying phases for about an year. The mean length of tagged individuals shows a positive correltion with the water temperature during the growing period. The growth is depressed at less than 10℃ in February, and accelerated at above 15℃ in May. The rapid growth (1.29 ㎝/dry) occurs at 15-18℃ during May-June and the maximum length is shown at 20-21℃ in early August. Daily net production estimated by the oxygen light and dark bottle method is 11.2gC/㎡/day in June. The annual value calculated by the integration of the daily net production, growth rate and biomass is 745 gC/㎡/yr. Net production estimated from the biomass change only is 287 gC/㎡/yr. But this must be an underestimated value, because the loss of considerable biomass by shedding is not included.

Objectives:This study investigated the effects of social support and chronic medical conditions on depressive symptoms in elderly people living alone in a rural community. Methods:Sociodemographic information on 173 subjects aged 65 years or older who lived alone in a rural community and were recipients of National Basic Livelihood Security was collected and analyzed. All participants completed the Korean Form of the Geriatric Depression Scale and the Lubben Social Network Scale. Additionally, the current prevalence of chronic medical conditions that interfere with the activities of daily living was examined. Multiple logistic regression analysis was conducted to analyze the associations of social support and chronic medical conditions with depressive symptoms. Results:Social support(odds ratio: OR, 0.96; 95% confidence interval: 95% CI, 0.92-0.99) and chronic medical conditions(OR, 1.59; 95% CI, 1.23-2.05) were significantly associated with depressive symptoms in all subjects. When analyzed by gender, social support served as a protective factor against depressive symptoms in elderly men only(OR, 0.91; 95% CI, 0.83-0.99), and chronic medical conditions increased the risk of depressive symptoms in elderly women only(OR, 1.74; 95% CI, 1.26-2.40). Furthermore, osteoarthritis and lumbar pain were risk factors for depressive symptoms in all subjects(OR, 2.24; 95% CI, 1.10-4.56 and OR, 2.10; 95% CI, 1.08-4.12) and in elderly women(OR, 4.07; 95% CI, 1.68-9.84 and OR, 3.34; 95% CI, 1.47-7.57), respectively. Conclusion:This study indicates that improving the social support and managing the chronic medical conditions of elderly people living alone are important for the prevention of depression in this population. Additionally, the present results suggest that it is necessary to establish different depression-prevention strategies for elderly men and women living alone.
