Various characteristics of the object being lifted are known to affect the biomechanical, physiological, and psychophysical stresses. The object characteristics to be considered in the design process of lifting tasks are weight, shape, stiffness, and availability of handles and similar coupling devices. In this study, a prototype Polypropylene laminated bag with carrying handles was designed to decrease the physical stress of people who handle these bags. Physiological and psychophysical approaches as well as subjective ratings were applied to evaluate the effects of handles provided on the designed PP laminated bag. Statistical analysis showed that the VO2, heart rate, blood pressure, and Borg-RPE score for PP laminated fertilizer bag with carrying handles were significantly lower than those bags without handles. Moreover, Maximum Acceptable Lifting Endurance Time(MALET) measure, newly developed in this study, for bags with handles was significantly higher than those for bags without handles. It is thus recommended that the various types of bags and boxes be equipped with handles to reduce the musculoskeletal, physiological, psychophysical, and subjective perceived stresses.

This study was conducted to investigate the eating habits, self-perception of body image, and weight control behavior in Korean adolescents by gender. Data pertaining to 70,809 subjects(male 37,090, female 33,719) were obtained from the sixth Korea Youth Risk Behavior Web-based Survey(2010). The rate of skipping breakfast was 42.5% in male, and 45.8% in female students. The intake frequency of vegetable, milk, soda, fast food, and instant noddles was higher in male than female students. Moreover, 33% of male and 31.9% of female students considered themselves to be somewhat or very obese. Notably, 2.3% of underweight students considered themselves to be obese. Weight control measures were practiced in 44.6% of male, and 54.6% of female students. Meal restrictions were used more frequently to control weight by females, while exercise was used more by males. The perceived stress level was higher in female than male students, especially that due to appearance. Therefore, integrated and personalized high school nutrition programs according to gender should be implemented to establish proper body image perception and eating habits, as well as to develop selfesteem.

Purpose: This study was performed to identify the level of stress perceived by nurses who attend dying patients in the cancer care unit; their understanding regarding end-of-life care and related training needs. Methods: A cross-sectional descriptive study was conducted with 151 nurses stationed at the cancer care units of four general hospitals located in Seoul and Gyeonggi province in Korea. Data were collected using self-reported questionnaires and the response rate was 96%. The data were analyzed using t-test, ANOVA and Pearson's correlation analysis. SPSS 12.0 was used for data analysis. Results: Nurses experienced a high level of stress in the end-of-life care settings. Their understanding of end-of-life care was above the mid-point of the scale while their training needs for end-of-life care was relatively high. The more experienced the nurses were, the more stressed they were, particularly due to excessive workload. Nurses who served longer in the cancer unit tended to show greater needs for end-of-life care training. Conclusion: This study found nurses perform end-of-life care with a high level of stress but with insufficient understanding, and thus, showed great needs for related training. Such findings can be useful to develop an end-of-life care training program for nurses.

We surveyed 553 middle school students living in Incheon using questionnaires to compare their food behaviors and snack intake patterns according to weight groups based on BMI. Mean BMI was 20.3 for males and 19.6 for females. The rate of underweight, normalweight and overweight students was 33.3, 51.7, and 15.0%, respectively. Compared to the other two groups, the overweight students perceived their body shape more accurately (p<0.01). Regarding the reasons for skipping dinner, the most frequent answer by the underweight students was 'because of snacks', while that of the overweight students was 'to lose weight' (p<0.01). The normalweight students were found to eat a Korean traditional type breakfast more frequently than the other weight groups (p<0.05). The overweight female group was more likely to overeathabitually, whereas the normalweight and underweight groups tended to overeat when they were under stress (p<0.05). As for the amount of the snack intake, the overweight male students replied that they eat quite a lot of snacks. As a conclusion, the problems found in the underweight group were unbalanced diet and the disturbance of regular meal patterns due to inappropriate snack intake. The problems shown in the overweight group were overeating due to habit or stress, fast eating speed and large amount of snack intake.

Manufacturing workers face increased fatigue and stress due to environmental factors in workplace such as noise and vibration. Addressing this issue requires creating conducive rest spaces; however, the existing conditions of rest spaces in manufacturing workplace are subpar and lack sufficient scholarly evidence. This study investigated the effect of nature-based rest spaces on the physical and emotional recovery from fatigue on manufacturing workers. Three manufacturing complexes with nature-friendly rest spaces were selected, and 63 manufacturing workers participated in the study. The measurement tools included the Multidimensional Fatigue Scale (MFS) for fatigue levels, physiological indicators (blood pressure and heart rate), and emotional indicators (Zuckerman Inventory of Personal Reaction Scale; ZIPERS, Perceived Restorativeness Scale; PRS, Profile of Mood States; POMS and State-Trait Anxiety Inventory; STAI). The study compared recovery levels during a 7-minute rest between a space without plants and a space with natural elements. The results indicated a significant reduction in systolic and diastolic blood pressure of participants in green rest spaces compared with those in conventional rest spaces. Regarding fatigue levels, green rest spaces showed a decrease in systolic blood pressure in the middle-fatigue and high-fatigue groups. Positive feelings increased in green spaces, whereas negative emotions decreased, suggesting that short breaks in nature-friendly environments effectively promote workers' physical and emotional recovery. Furthermore, this study emphasizes the importance of green space in various work environments to promote well-being in workers.

Objectives: The purpose of this study was to identify the related factors of dental caries and periodontal disease in adolescents from Korean multicultural families, thereby helping to reduce the prevalence rate of oral disease. Methods: The subjects were 710 multicultural adolescents recruited using a web-based survey, National 2015 Korean Youth Risk Behavior, from the Korean Center for Disease Control. A multicultural family was defined in this study as one having an immigrant mother or father. Oral symptoms included dental caries and periodontal disease. Toothache was defined as a symptom of dental caries. Tender or bleeding gums were defined as symptom of periodontal disease. For statistical analysis, Statistical Package for Social Sciences (SPSS) Version 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behavior, and oral health behavior. Finally, to investigate the associations among oral disease symptoms, logistic regression analysis was performed. Results: Toothache was significantly higher in female 1.52 (95% CI; 1.45-1.60), high school 1.23 (95% CI; 1.18-1.28), women school 1.10 (95% CI; 1.05-1.16), individuals with poor economic status 1.45 (95% CI; 1.30-1.52), and participants who consumed alcohol 1.32 (95% CI; 1.27-1.37). Toothache related to perceived health status was significantly lower in the healthy group 0.69 (95% CI; 0.64-0.75), and was higher in usual stress group 1.65 (95% CI; 1.57-1.74). Gum bleeding was significantly higher in female 1.32 (95% CI; 1.27-1.37), high school 1.15 (95% CI; 1.10-1.19), and individuals with poor economic status 1.38 (95% CI; 1.27-1.50). Gum bleeding related to perceived health status was significantly lower in the healthy group 0.68 (95% CI; 0.63-0.74), and was higher in usual stress group 1.54 (95% CI; 1.46-1.62). Conclusions: Taking into account of social and economic levels, and dietary habits in the multicultural families adolescents, further education and support will be needed for oral disease prevention and early treatment.

Ten Dongs were selected according to the systematic cluster sampling in Koryong Gun, and the survey was conducted on 571 women in the age between 30-69 years. The first survey was performed for 6 days between August 27 to September 1, 1999 with the investigation rate of 60.3%, and the second survey was performed in November with the investigation rate of 91.8%. The contents of survey included demographic characteristics, health behaviors, dyspepsia symptom score, sleeping induction time and the degree of sleep satisfaction, and degree of stress in the subjects. The dyspepsia symptom score was in the average 13.4 points out of a total 44 points and was the highest in the 50-59 year-old age group with 13.9 points. The sleep induction time was in the average of 35 minutes and was the highest in the 50-59 year-old age group with 40.9 minutes; the degree of sleep satisfaction was in the average of 7.9 points and was the lowest in the 50-59 year-old age group with 7.5 points. The stress score was in the average of 18.3 points and was highest in those subjects in their 40's and 50's with 18.7 points. When the correlation among the stress score, the degree of sleep satisfaction and dyspepsia symptom score was analyzed, the results showed that he stress score and the degree of sleep satisfaction showed a significant negative correlation and that the stress score and dyspepsia symptom score showed a significant positive correlation. Also, a significant negative correlation was found between the degree of sleep satisfaction and dyspepsia symptom score. According to each age group, a significant correlation was revealed among the stress score, dyspepsia symptom score and the degree of sleep satisfaction in those subjects over 40 years of age compared to those subjects who were younger than 40 years of age. As for educational level, the correlation among the stress score, the degree of sleep satisfaction and dyspepsia symptom score was higher in those subjects with less than middle school education compared to those subjects with more than high school education. When those factors that effects on the dyspepsia symptom score were analyzed with multiple regression, the results showed that the level of stress and chronic diseases were selected as significant variables. When those factors that affected on the degree of sleep satisfaction were analyzed, the sleep induction time and presence of chronic diseases and stress were selected as significant variables. Those women in their 50's who live in rural areas showed the highest level of stress, lowest the degree of sleep satisfaction, and highest level of dyspepsia, indicating that they need stress management. Also, since stress was showed to be a significant variable effecting on dyspepsia or the degree of sleep satisfaction, it is concluded that health promotion is possible through stress management. More studies are needed in the future on coping resources that would strengthen coping against stress, and by conducting studies on stress and related factors on community people, the measures of mental health promotion need to be developed.

Objectives: This study aimed to identify factors associated with smoking relapse. Methods: The study sample was recruited among subjects who were enrolled in the smoking cessation clinic of a public health center and had succeeded in quitting smoking for at least six months. A total of 159 male subjects were followed via mail survey one year later. The independent variables in the analyses were socio-demographic characteristics, smoking history and behavior, receipt of smoking cessation aids, health behaviors and components of the health belief model (HBM). The dependent variable was smoking relapse assessed one year after quitting. Ordered logit regressions were used to identify factors associated with smoking relapse. Results: The relapse rate of the ex-smokers in our sample was 25.8%, and the occasional smoking rate was 17.0%. Univariate analyses revealed that only factors related to the HBM, such as perceived susceptibility to diseases (p<0.01), perceived severity of diseases (p<0.01), perceived health benefits of not smoking (p<0.01), perceived barriers to quitting smoking due to increasing stress and difficulty in social life (p<0.01), and self-efficacy (p<0.01) were associated with the likelihood of relapse for ex-smokers. Ordered logit analyses yielded two significant factors affecting the likelihood of relapse, the perceived barriers to quitting smoking and self-efficacy. Conclusions: Our results indicate that higher levels of barriers to quitting smoking and lower levels of self-efficacy were significantly related to risk of smoking relapse. These findings may be useful for identifying those at highest risk for relapse and choosing the optimal strategies for prevention of relapse for ex-smokers.

The purpose of the study is to analyze the relationship between the warning picture on a cigarette pack and non-smoking attempt, which is expected to contribute to the negative perception of smoking as a research subject about smoking adolescents. An online survey data of the Youth Health Behavior in 2018 has been used, and 3,722 adolescents who are currently smokers were selected for the study. For the measurement of variables, demographic sociology, health-related, and smoking-related factors have been revised, and multivariate binomial logistic regression analysis has been performed. The perception rate of cigarette warning pictures among adolescents who smoke currently is 84.7%, and among them, the attempt rate to quit smoking is 72.8%. As a result of the multivariate binomial logistic regression analysis, there is a meaningful relationship between adolescent smokers' attempts to quit smoking and whether they perceived cigarette pack warning pictures, and school grade year, academic performance, stress perception, and ease of purchasing cigarettes have been also expressed as meaningful variables. To be based on the result, it is necessary to manufacture to design a cigarette pack warning picture that can be easily recognized by smoking adolescents in the future.
