Elevated high-sensitivity C reactive protein (hs-CRP) levels and metabolic syndrome are considered important predictors of cardiovascular mortality. This study examined the influence of the alcohol consumption level on the hs-CRP level and the prevalence of metabolic syndrome in South Koreans. The study subjects were 3,884 participants (${\geq}19$ years) from the KNHANES in 2015. The subjects were divided into four groups according to their alcohol consumption; None (none-alcohol consumption), Low (less than 15 g/day), Medium (15~29.9 g/day), and High (over than 30 g/day). The odds ratio for high-risk hs-CRP of men was significantly lower in the Low or Medium groups compared to the None group. In women, the odds ratio for high-risk hs-CRP was not decreased in the Low or Medium groups but was significantly higher in the High group than in the None group. Compared to nondrinkers, the prevalence of metabolic syndrome was lower in the Low group and Medium group in both men and women, whereas it was significantly higher in the High group in men only. In particular, the prevalence of low HDL-cholesterol was lower in all drinking groups. When the confounding factors were adjusted, the odds ratio for low HDL-cholesterol appeared to decline in the Low groups in both men and women. On the other hand, in the Medium group, women showed an elevated odds ratios of high blood pressure (HBP) and high fasting plasma glucose but men showed an elevated odds ratios of HBP and high triglyceride levels. The overall results suggest that low alcohol consumption is more appropriate than medium alcohol consumption. Nevertheless, more study will be needed to evaluate the appropriate alcohol consumption level.

Recently game addiction of young people has become a social issue. Therefore, many studies, mostly surveys, have been conducted to diagnose game addiction. In this paper, we suggest how to distinguish levels of addiction based on EEG. To this end, we first classify four groups by the degrees of addiction to internet games (High-risk group, Vigilance group, Normal group, Good-user group) using CSG (Comprehensive Scale for Assessing Game Behavior) and then measure their Event Related Potential(ERP) in the Go/NoGo Task. Specifically, we measure the signals of P300, N400 and N200 from the channels of the NoGo stimulus and Go stimulus. In addition, we extract distinct features from the discrete wavelet transform of the EEG signal and use these features to distinguish the degrees of addiction to internet games. The experiments in this study show that High-risk and Vigilance group exhibit lower Go-N200 amplitude of Fz channel than Normal and Good-user groups. In Go-P300 and NoGo-P300 of Fz channel, High-risk and Vigilance groups exhibit higher amplitude than Normal and Good-user group. In Go-N400 and NoGo-N400 of Pz channel, High-risk and Vigilance group exhibit lower amplitude than Normal and Good-user group. The test after the learning study of the extracted characteristics of each frequency band from the EEG signal showed 85% classification accuracy.

Objectives: Korean elderly people are known to consume diets high in carbohydrates low in vegetables compared to other age groups. This study evaluated the chronic disease risks and nutritional status in this group based on the percentage of energy from carbohydrates and the frequency of vegetable intake. Methods: Using the 2007~2009 Korean National Health Nutrition Examination Survey data, except those who were undergoing treatment for chronic disease, final 1,487 subjects aged 65 and older were divided into 4 groups: moderate carbohydrate energy ratio of 55~70% and low frequency of vegetable intake defined as less than 5 times per day (MCLV), moderate carbohydrate ratio and high frequency of vegetable intake more than 5 times (MCHV), high carbohydrate energy ratio above 70% and low frequency of vegetable intake less than 5 times (HCLV), and high carbohydrate ratio and high frequency of vegetable intake more than 5 times (HCHV). All data were analyzed after the application of weighted value, using a general linear model or logistic regression. Results: More than half of Korean elderly consumed diets with HCLV, and this group showed poor nutritional status and lower frequency of intake of most food items, but with no risk of chronic disease such as diabetes, obesity, hypertension, cardiovascular disease or anemia probably due to low intake of energy. On the contrary, MCHV group with a high percentage of energy from fat and protein showed the highest intake of energy and most nutrients, the highest frequency of intake of most of food items and a tendency of high risk of abdominal obesity, being followed by the MCLV group. Meanwhile, HCHV group showed a tendency of high risk of hypertension, followed by HCLV group with low frequency of intake of vegetables compared with the two moderate carbohydrate groups. Conclusions: The results suggested that the percentage of energy from carbohydrate and the frequency of vegetable intake affected the nutritional status, but not significantly affected the risk of chronic disease in Korean elderly. Further studies using more detailed category of % energy from carbohydrates and of type and amount of vegetables with consideration of individual energy intake level, excessive or deficient, are needed to confirm the results.

Purpose: This study was to investigate the relations and odds ratio between hs-CRP and the risk factors of metabolic syndrome according to glucose intolerance and diabetes among the residents of a rural community. Methods: The subjects include 1,968 adults aged from 40 to 70 who were divided into four groups and a diabetes group according to glucose intolerance to compare the relations and risk ratio between hs-CRP and the risk factors of metabolic syndrome. Results: The results reveal that the greater the subjects' glucose intolerance was, the higher their hs-CRP became and the more risk factors of metabolic syndrome they had. The impaired glucose tolerance group showed 1.7 times higher blood pressure than the control group. The diabetes group showed a high odds ratio with 2.3 times higher blood pressure, 2.2 times higher abdominal obesity, and 2.4 times higherW/Ht than the control group. And the odds ratio increased significantly by 1.7 times in the hs-CRP intermediate risk group and 2.5 times in the high risk group compared with the control group. Conclusion: Considering the study results, it is very important to monitor abdominal obesity, blood pressure and the intermediate and high risk group of hs-CRP in order to reduce the contraction of cardiovascular diseases.

Purpose: This study aimed to investigate the effects of various factors on smartphone addiction according to types of risk groups among middle school students. Methods: Data of 223 students were collected from February 1st to 22nd of 2020. The collected data were analyzed through t-test, χ² test, correlaton coefficients, and multiple regression analysis. The smartphone addiction scale was used to classify the participants into two groups; 18.8% (n=42) of the total respondents were categorized as the addiction risk group and 81.2% (n=181) were categorized as the general population group. Results: The factors associated with the students in the high risk group were grade (t=3.89, p=.036) and religion (F=3.79, p=.044). In the high risk group, psychological anxiety (β=.39, p=.005) and relapse of internet addiction (β=.38, p=.006) explained 46.0% of smartphone addiction, while in the normal risk group, relapse of internet addiction (β=.42, p<.001), psychological anxiety (β=.22, p=.004), tolerance of internet addiction (β=.17, p=.007), and academic stress (β=.14, p=.027) explained 51.0% of smartphone addiction. Conclusion: In order to prevent smartphone addiction in middle school students, a more specific nursing intervention is needed that can reduce psychological anxiety and relapse of internet addiction. It is clear that urgent measures need to be taken for the highly addicted students such as academic counseling.

Stow net fishery is one of the fishery with high fishing work accidents in southwestern sea of Korea. We conducted to serve as basic data for improving the healthy and safe working environment of fisher using risk assessment process (ISO45001) with fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) from 2016 to 2018. The average occurrence rate of victim in this fishery was 9.04%, 16.7 times more than such rate in all industries. In addition, the average fatality rate was found to have a very serious level management to 31.06‱, 27.7 times more than such rate in all industries. The safety hazards of stow net fishery was more likely to occur by other general industrial groups, with more severe consequences after the accident. According to 4M analysis, 58.6% of all accidents were caused by human factors, 24.0% by environmental factors, 16.0% by mechanical factors, and 1.5% by managerial factors, respectively. The occurrence frequency by accident type was the highest in 187 cases (32.2%) for struck by object, 158 cases (27.2%) for slipping, and 94 cases (16.2%) for being in contact with machinery. Severity is the highest for others such as diseases etc., in the order of being struck by object, being in contact with machinery, falling from above slipping, collapsing, bumping, and burning. Being struck by object, being in contact with machinery, and slipping are high-risk groups, falling from above others, bumping, and burning are medium-risk groups based on the risk assessment using the occurrence frequency and severity of accident. The obtained results are expected to contribute to the safe operation environment subsidy for fishing crews on the stow net fishing vessel.

Objective : The purpose of this study was to investigate the effectiveness of the mental health improvement program in Korean firefighters. Methods : A total of 502 firefighters working at Daegu, Ulsan and Gumi participated in the mental health improvement program for an 8-week period. The program included evaluation and counseling as well as psychoeducation for mental health awareness. Subjects were divided to two groups including the PTSD high risk group and PTSD non-high risk group. Results : The program resulted in a significant decrease in mean scores of depression and insomnia for all firefighters. PTSD high risk group showed a significantly higher level of depression, anxiety, and insomnia. Multiple logistic regression analysis with PTSD high risk group as a dependent variable indicated that moderate depression was a high-risk factor for PTSD in firefighters, as compared to no depression ; in addition, subthreshold and moderate insomnia was another risk factor. Conclusion : The evaluation and management of psychopathologies including depression and insomnia associated with traumatic events can be helpful to improve the mental health of firefighters.

Objectives: The objective of this study was to assess the gender differences in the relationship between alcohol use behaviors and the risk of metabolic syndrome among Korean adult population. Methods: Data from the Korean National Health and Nutrition Examination Survey (5th, 2010) was analyzed. Using the Alcohol Use Disorders Identification Test, subjects were classified into 4 groups including non-drinking, low-risk drinking, medium-level alcohol problem, and high-level alcohol problem group. Metabolic syndrome and its components were compared among the alcohol behavior groups by gender. Results: The odds ratio vs. non-drinking group for metabolic syndrome was significantly higher in male medium and high-level alcohol problem group. In female, high-level alcohol problem group showed significantly higher odds ratio for metabolic syndrome. Blood pressure and HDL-cholesterol were likely to be higher with the excessive drinking behaviors in both men and woman. Triglyceride level in men was significantly higher in the medium and high-level alcohol problem group than non-drinking group. Although fasting glucose level did not show differences among drinking groups, the odd ratios vs. non-drinking group for the hyperglycemia (${\geq}$ 100mg/dl) were significantly higher in female drinking groups. Conclusions: Problematic alcohol drinking is likely to increase the risk of metabolic syndrome in Korean adults.

Purpose: The purpose of this study was to investigate the nutritional intake status, according to the risk of diabetic complications in Type 2 diabetes patients. Methods: This was a secondary data analysis study that included 83 patients. The nutritional intake was assessed, using 24-hour dietary recall. The risk of diabetic complications was measured, using the Framingham Risk Score (FRS) and Michigan Neuropathy Screening Instrument Questionnaire (MNSIQ). The nutritional intake was analyzed using the CAN-pro 4.0 program. Data were analyzed using descriptive statistics, Chi-square test, and Independent t-test, using the SPSS WIN 26.0 program. Results: The mean FRS and MNSIQ scores for the participants was 14.46± 4.09 and 2.30± 2.22, respectively. Thirty two participants (38.6%) were in the high-risk groups for cardiovascular disease and peripheral neuropathy. The participants consumed high amounts of grain and low amounts of vegetables, fruits, and dairy products when compared to the recommended intake. However, the nutritional intake did not differ according to FRS or MNSIQ levels. Consumption of vegetables and fruits were significantly different between high and low risk groups of MNSIQ. Conclusion: It is necessary to consider the composition of dietary intake to improve the imbalanced diet in Type 2 diabetes patients and prevent diabetic complications. Type 2 diabetes patients should reduce the intake of grains and sodium, and increase vegetable intake. More deliberate future studies are needed, to investigate the relationship between food intake and the risk status for diabetic complication.
