본 연구는 요가수련이 우울감에 미치는 영향을 밝히고자 한 것이다. 첫째 연구는, 우울감에 미치는 요가수련의 효과를 일차적으로 검증하기 위한 전(前) 실험연구로서, 단일집단 사전-사후 비교설계(one group pretest-posttest design)에 따라 요가수련 전ㆍ후 일시적인 우울 기분(depression mood)을 비교하였다. 그 결과 요가수련 전보다 수련 후 피험자들의 우울 기분이 완화되었으며, 이 차이는 .001수준에서 통계적으로 유의하였다. 둘째 연구는, 요가수련 정도에 따른 우울증상(depression symptom)에 관한 설문 조사연구로서, 요가수련 빈도 및 기간이 2주 정도 비교적 지속적인 우울감 감소에 미치는 효과를 검증하고자 하였다. 그 결과, 수련 빈도와 기간이 증가함에 따라 우울증상이 가벼워지는 것으로 나타났으며, 수련 빈도에 따른 우울증상의 차이(F=3.17, p<.05)와 기간에 따른 우울증상의 차이(F=4.25,p<.01) 모두 통계적으로 유의미하였다. 종합적으로, 요가수련은 일시적인 우울기분(depression mood) 및 우울증상(depression symptoms)에 긍정적인 영향을 미치는 것으로 나타났으며, 따라서 요가수련이 우울감을 개선하는 데 도움을 줄 것으로 기대할 수 있다. 또한 빈도와 기간이 증가함에 따라 우울감이 낮아졌으므로, 지속적이고 장기적인 요가수련이 의미를 가지는 것으로 보인다. The purpose of this study was to analyze the effects of yoga practice on depression mood and depression symptoms. To check out participants` change of depression level, this empirical investigation assessed the effects of yoga practice on depression mood and depression symptoms as a function of frequency and period of yoga practice. A survey was conducted by using K-DACL(Depression Adjective Checklist-Korean version) and BDIⅡ(Beck Depression InventoryⅡ). There were 201 yoga participants in the survey, consisting of individuals at three yoga institutions in Seoul. Correlated samples t test(two-dependent samples t test) and one-way ANOVA were applied for assessing the effect of yoga practice on depression. The main findings indicated that the yoga practice had positive influences on depression mood and symptoms. To be specific, the results were as follows: First, the perceived level of participants` depression mood was significantly decreased after yoga practice. Second, both frequency and period of yoga practice had bearings on the reduction of depression symptoms. As a result, this study showed how important steady participation in yoga programs was.

본 연구는 머신러닝을 활용하여 급성 뇌졸중 퇴원 환자의 중증도 보정 사망 예측 모형 개발을 목적으로 시행하였다. 전국 단위의 퇴원손상심층조사 2006~2015년 자료 중 한국표준질병사인분류(Korean standard classification of disease-KCD 7)에 따라 뇌졸중 코드 I60-I63에 해당하는 대상자를 추출하여 분석하였다. 동반질환 중증도 보정 도구로는 Charlson comorbidity index(CCI), Elixhauser comorbidity index(ECI), Clinical classification software(CCS)의 3가지 도구를 사용하였고 중증도 보정 모형 예측 개발은 로지스틱회귀분석, 의사결정나무, 신경망, 서포트 벡터 머신 기법을 활용하여 비교해 보았다. 뇌졸중 환자의 동반질환으로는 ECI에서는 합병증을 동반하지 않은 고혈압(hypertension, uncomplicated)이 43.8%로, CCS에서는 본태성고혈압(essential hypertension)이 43.9%로 다른 질환에 비해 가장 월등하게 높은 것으로 나타났다. 동반질환 중중도 보정 도구를 비교해 본 결과 CCI, ECI, CCS 중 CCS가 가장 높은 AUC값으로 분석되어 가장 우수한 중증도 보정 도구인 것으로 확인되었다. 또한 CCS, 주진단, 성, 연령, 입원경로, 수술유무 변수를 포함한 중증도 보정모형 개발 AUC값은 로지스틱 회귀분석의 경우 0.808, 의사결정나무 0.785, 신경망 0.809, 서포트 벡터 머신 0.830로 분석되어 가장 우수한 예측력을 보인 것은 서포트 벡터머신 기법인 것으로 최종 확인되었고 이러한 결과는 추후 보건의료정책 수립에 활용될 수 있을 것이다. The purpose of this study was to develop a severity-adjustment model for predicting mortality in acute stroke patients using machine learning. Using the Korean National Hospital Discharge In-depth Injury Survey from 2006 to 2015, the study population with disease code I60-I63 (KCD 7) were extracted for further analysis. Three tools were used for the severity-adjustment of comorbidity: the Charlson Comorbidity Index (CCI), the Elixhauser comorbidity index (ECI), and the Clinical Classification Software (CCS). The severity-adjustment models for mortality prediction in patients with acute stroke were developed using logistic regression, decision tree, neural network, and support vector machine methods. The most common comorbid disease in stroke patients were hypertension, uncomplicated (43.8%) in the ECI, and essential hypertension (43.9%) in the CCS. Among the CCI, ECI, and CCS, CCS had the highest AUC value. CCS was confirmed as the best severity correction tool. In addition, the AUC values for variables of CCS including main diagnosis, gender, age, hospitalization route, and existence of surgery were 0.808 for the logistic regression analysis, 0.785 for the decision tree, 0.809 for the neural network and 0.830 for the support vector machine. Therefore, the best predictive power was achieved by the support vector machine technique. The results of this study can be used in the establishment of health policy in the future.

The study compared eating and physical activity related behaviors and self-esteem between healthy weight and obese children by presenting 175 primary school students in Busan City and Gyeongsang province with a self-reported questionnaire and Coopersmith`s self-esteem inventory. The questionnaire was composed of 25 items, weighted primarily by a Likert scale. The self-esteem inventory presented to the students comprised 25 Yes or No response questions to different statements. The study found obese children were more likely to think they always had to control their weight (p = 0.000), reportedly measuring their weights significantly more than the healthy weight children. Also the study found that obese children are significantly more likely than healthy weight children to go on a diet, however neither group were successful in losing weight as the duration of the diet in 79.5% of the total sample lasted no longer than one week. In comparison to healthy weight children, obese children reported that they consumed fewer snacks during the day, avoided snacking subsequent to an evening meal and exercised more frequently for as long as physically possible. Interestingly, we found no difference of reported self-esteem between groups, though the obese group were more likely to answer that their parents did not understand them (p = 0.055). Based on these findings, we concluded that the obese children who participated in the study were more aware of their body weights than the healthy weights children. It may be necessary to investigate further the relationship between self-esteem and participants` weights while considering other variables such as personality and body image.

Since the 1980`s, despite the conclusion of a number of studies in Western countries focusing upon weight maintenance there has been no similar research in Korea which takes into account the contrasts of culture and eating habits between east and west. In order to identify eating, snacking and exercise behaviors, 24 female university students who have maintained weight for at least a year were enrolled for an 11 day study. Participants were required to sign into the program and complete the questionnaire, answering questions by concerning what they ate and did everyday. After excluding unanswered questions, data over 11 days were exported into the Microsoft Excel spreadsheet, then both ANOVA and Kendall`s tau correlation were applied with SPSS. 75% of weight maintainers had normal BMI (18 - 23.5) in relation to Korean standard, and appeared to eat a main meal smaller than moderate in portion size. Only two days showed that amount of breakfast eaten negatively correlated with lunch (p < 0.05), while no correlations between amounts of lunch and dinner eaten over all study period. Compared with breakfast or lunch, dinner was usually larger in portion size, but some variables such as TV viewing, restaurant meals, number of people at dinner table seemed not correlated with amount of dinner eaten. In addition, the weight-maintainers reported they rarely consumed snacks or sweetened beverages. Unlike their western counterparts, few participants reported that they took part in regular exercise during the day, which may lead us to the conclusion that these young female weight maintainers seem to maintain their weight with eating behaviours such as ``eat small portion``, ``avoid snacking`` and ``avoid soft drinks`` rather than doing regular exercise. The study did not include a control group, and was foreshortened due to technical difficulties so it may be necessary to repeat the study while considering these two points.

Since obesity has been a crucial issue regarding children`s health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing ``key word`` searches from several web engines: ``obesity`` ‘children obesity`` ``behavior`` ``habit`` ``eating behavior or habit` ``exercise`` ``physical activity`` and ``daily behavior``. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children`s behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

코로나19 유행상황에서 청소년의 인지된 건강행태와 변화된 일상생활과의 관계

백설화(Seol-Hwa Baek),이진영(Jin-Yeong Lee) 한국산학기술학회 2023 한국산학기술학회논문지 Vol.24 No.4

본 연구는 제17차(2021년) 청소년건강행태조사 원시자료를 이용한 2차 자료 분석연구로 청소년의 인지된 건강행태가 코로나19로 인한 일상생활변화에 미치는 영향 요인을 확인하는 것이다. 수집된 자료의 분석은 SPSS/WIN 26.0 프로그램을 활용하여 빈도분석과 교차분석, 독립표본 t검정, 다중 로지스틱 회귀분석을 실시하였다. 그 결과 인지된 건강행태와 코로나19로 인한 일상생활변화와의 관계는 성별(p ≤ .001), 학교급(p ≤ .001), 주관적 건강상태(p ≤ .021), 주관적 스트레스인지(p ≤ .023), 주관적 수면 충족(p ≤ .007)이 신체활동, 음주, 흡연, 우울감에 통계적으로 유의하게 영향을 미치는 것으로 나타났다. 따라서 청소년의 코로나19로 인해 변화된 일상생활을 개선하기 위해 주관적 건강상태와 스트레스 관리 및 수면의 질 등을 고려해야 할 것이다. This is a secondary data analysis study using the raw data of the 2021 Youth Health Behavior Survey to identify the factors associated with perceived health behaviors due to alterations in the daily life of adolescents caused by COVID-19. Data were analyzed using frequency analysis, chi-square test, independent sample t-test, and multiple logistic regression analysis, and all analyses were performed using the SPSS/WIN 26.0 program. Our results showed that the changes in daily life due to COVID-19, such as physical activity, alcohol drinking, smoking, and depression, were statistically associated with gender (p ≤.001), school level (p ≤.001), subjective health status (p ≤.021), subjective stress perception (p ≤.023), and subjective sleep satisfaction (p ≤.007). This indicates the need to consider subjective health status, stress management, and sleep quality to help improve adolescents health behaviors altered due to the COVID-19 pandemic.

In order to investigate how to maintain normal weight under independent living conditions, twenty female university students were enrolled and asked to complete a questionnaire over a 10-day study period. T-test, Spearman`s correlation and multiple regression analysis were applied to describe characteristics of weight maintainers` habits on a daily basis. The results were as follows: They always comsumed small or moderate-sized meals. 2~3 co-eaters usually had dinner together at home while not watching TV. They also showed healthy eating behaviors such as no snacking, very little amounts of soft drinks, coffee and alcohol consumption. The always normal weight maintainers, however, were not physically active at all. When being with co-eater(s), they ate larger-sized dinners (β=0.585, R2=30.6), and the more co-eaters they had at the dinner table, the greater BMI they got (β=0.547, R2=29.9). As a result of this study, encouraging young adult people to exercise on a regular basis is required, even though they seem to succeed in maintaining normal weight without being active physically. Further study is necessary to investigate how co-eaters would influence the amount of food eaten. (Korean J Community Nutrition 14(3):295~305, 2009)
