PURPOSE: This study analyzed the degree of job stress and caffeine intake in workers in industrial positions in order to determine the relationships between job stress and caffeine intake. METHODS: For this purpose, this study conducted a survey targeting 361 blue collar workers working for K manufacturing company, Gwangju. RESULTS: The total score for job stress in subjects was 72.7 ± 6.8 points/100 points. According to job stress, subjects were categorized as follows: Q1 for the group who had the least stress; Q2 for the group who had little stress; Q3 for the group who had a lot of stress, and Q4 for the group who had the most stress. As for the effects of caffeine on health, 57.1% thought that caffeine is helpful and not harmful if taken properly while 17.3% responded that less caffeine consumption is better. Daily intake of caffeine according to stress was presented as: 172.0 ± 85.3 mg in Q1, 179.0 ± 83.7 mg in Q2, 187.9 ± 81.4 mg in Q3, and 214.2 ± 147.3 mg in Q4 (p < 0.05). The percentages of caffeine consumption compared to the daily safe limit in subjects were: 43.0 ± 21.3, 44.8 ± 20.9, 47.1 ± 20.4, and 53.6 ± 36.8% in Q1, Q2, Q3, and Q4, respectively (p < 0.05). Adverse effects such as nausea or vomiting from caffeine were most common in Q4 (p < 0.05) CONCLUSION: As a result, higher stress in blue collar workers working for K manufacturing company was associated with more caffeine consumption. Groups with a lot of stress (Q4) consumed approximately 50% of daily safe limit of caffeine. Considering the results above, this study suggests that further research on more precise caffeine intake and its effects is needed.

Objectives: This paper aimed to provide an in-depth analysis of the factors influencing the dietary habits of male and female workers at a facility in Gwangju and their awareness of the same. Methods: A total of 32 workers were divided into eight groups based on work type, gender, and age, and focus group interviews (FGIs) were conducted. The FGIs included cognitive, behavioral, and environmental questionnaires based on dietary habits and the social cognitive theory. The interviews were analyzed by subject and sub-subject using audio recordings and transcriptions. Results: Male workers in the concerned company favored meat while female workers preferred vegetables, yet by and large, the preferences were irregular. Male workers living alone frequently ate ready meals and female workers often skipped meals. An analysis of the factors influencing the study subjects’ dietary habits from the cognitive, behavioral, and environmental perspectives showed that the main factors negatively affecting their dietary habits were shiftwork, living alone, and drinking. Workers were unaware of these factors and their poor eating habits. Instead, male workers complained of poor cooking skills, while female workers complained of loneliness. Workers thus appeared to need the support of nutrition education and a counseling assistant to cope with this situation. Conclusions The study identified the fact that the absence of nutrition education left the workers unaware of their poor eating habits. The workers would need counseling and support to help them build healthy dietary habits. It would also be necessary to focus on raising the workers’ cognitive awareness of dietary habits and enhancing their behavioral ability to cope with bad eating habits through nutrition education that reflects the reality of their situation.

PURPOSE: This study was conducted to investigate and analyze the association between stress from shift and non-shift work as well as the effects living habits have on eating habits in order to identify why and how workers can improve their health and form proper eating habits for higher working efficiency. METHODS: The subjects of this study were 361 workers from K manufacturing company from April 7 to 11, 2014 and they were surveyed using a questionnaire. The subjects were divided into two groups according to working pattern: shift workers (n = 216) and non-shift workers (n = 110). RESULTS: In the general characteristics, there were significant differences in age, work career, work time, marriage, monthly income, and education levels between the two groups. For healthy behaviors, significant differences in subjective health status, moderate physical activity, drinking, smoking, and sleep time were observed between shift workers and non-shift workers. For eating habits, scores of non-shift workers having a regular mealtime, balanced meal composition, and vegetable and seaweed intakes were significantly higher than those of shift workers. The sum score of dietary habits in non-shift workers was also significantly lower than that in shift workers (p < 0.05). Total job stress score did not significantly differ between the two groups. CONCLUSION: The sum of eating habit scores according to work types was 16.1 ± 0.6 in non-shift workers and 14.0 ± 0.3 in shift workers. These results suggest that it is necessary to provide food suitable to characteristics of different workers according to work type which should be provided along with daily nutrition counseling to help subjects recognize their status.

Purpose: This study examined the factors influencing Nutrition Quotient for adults (NQ-A), focusing on workers in the manufacturing industry. Methods: The participants were 738 industrial workers in Gwangju. Their dietary information was analyzed using a questionnaire of NQ-A, which consisted of 21 checklist items and the general characteristics of the subjects. The scores of NQ-A and its 4 factors (balance, moderation, diversity, and dietary behavior) were calculated according to the general characteristics of subjects. The data were analyzed using a χ2 test, t-test, correlation, and multiple regression using SPSS 21.0 program. Results: The mean NQ-A score was 45.3 for the total subjects, indicating a low grade. Non-shift workers showed significantly higher scores for balance, diversity, and moderation factors than shift workers. Forty-three (8.7%) shift workers and 123 (50.8%) non-shift workers had good NQ-A scores, whereas 453 (91.3%) shift workers and 119 (49.2%) non-shift workers required monitoring for nutrition. The significant influencing factors of NQ-A were the working pattern (p < 0.001), gender (p < 0.001), family composition (p < 0.001), age (p < 0.001), and household income (p < 0.001). As a result of multiple regression analysis, there was a significant difference in the NQ-A score for moderation (F = 141.930, p < 0.001), diversity (F = 98.998, p < 0.001), balance (F = 52.329, p < 0.001), and dietary behavior (F = 12.895, p < 0.001). As a result, shift work and gender had the greatest influence on the balance (β = −0.372, p < 0.001), diversity (β = −0.316, p < 0.001), and moderation (β = −0.507, p < 0.001) factors in NQ-A. Gender had the most influence on the dietary behavior in NQ-A. Conclusion Shift work and gender were significant factors affecting NQ-A. To manage workers' health better, it will be necessary to prepare a nutrition education program according to the type of working pattern and gender.

The breast cancer is the second most common malignancy in pregnancy after cervical cancer. Pregnancy- associated breast caner tends to show unfavorable prognosis, because it is diagnosed at more advanced stage due to delay of diagnosis and treatment. For appropriate management, collaboration with physicians and obstetricians should make precise decisions considering gestational weeks and cancer stage at the time of diagnosis in a point of view from mother and fetus. A case of successful gestation and delivery after chemotherapy in a woman with inflammatory breast cancer diagnosed in the second trimester is presented with review of literature.

OBJECTIVES: The purpose of this study was to examine the influence of self-esteem and social support on the depression stati of some clinical nurses, and propose basic data for a depression care program. METHODS: Between March 31 and April 5 at 2006, a self-reporting questionnaire survey was administered to 200 nurses at a general hospital located in Gyeonggi-do. The Beck's Depression Inventory (BDI) was used to assess the subjects'depression stati. RESULTS: The average BDI score of the clinical nurses was 8.9+/-7.5, with 59% belonging to the normal category, 28% having mild depressive symptoms, and 13% with a moderate degree of depressive symptoms. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. According to a multivariate regression analysis, a significant association was found between self-esteem and social support in relation to the depression of clinical nurses. The effect of social support was found to not be significant in cases where the self-esteem was high: however, depression was significantly influenced by social support in cases where the self-esteem was low. CONCLUSION: Self-esteem and social support were observed to influence the depression stati of clinical nurses. Therefore, it is suggested that an increase in depression management programs is required to create systematic management to maintain an atmosphere of high self-esteem and close relationships to manage the depression of clinical nurses.

This study was carried out to investigate the relationship between brain magnetic resonance imaging (MRI) and neurological findings in welders exposed to manganese fume. Thirty five welders from a bus manufacturing factory who were occupationally exposed to low dose manganese fume were examined. We collected the information on the demo graphic factors and welding careers. Laboratory investigations included blood and urine manganese concentration and blood chemistry. Brain MRI was checked, and high signal intensity of the globus pallidus was graded from 0 to 3 compared to the white matter of the frontal lobe. Neurologic examination wart carried out. The results were as follows ; 1. The mean age of workers was 48.3+/-5.7 years, mean duration of welding was 21.4 +/-5.6 Years. 2. On brain MRI, high signal intensity in the globes pallidus was observed in 27 workers (77.1%) Among them, 18 cases (66.7%) showed remarkably high signal intensity (grade 2) Mean concentration of blood manganese was higher in those with high signal intensity and correlated to the grade of high signal intensity (p=0.02) 3. On neurologic examination, no workers showed the finding of typical parkinsonism. But 11 workers (31.4%) showed subtle neurological abnormalities such as gait without associated arm movement, postural instability, intention tremor, and so on. Blood manganese concentration of neurologically abnormal group was 2.4+/-0.7 microgram/dL, which was significantly higher, compared to 1.8+/-0.7 microgram/dL of neurologically normal group (p=0.03). 4. Among 27 workers who showed high signal intensity on brain MRI, 10 workers (37%) were neurologically abnormal. Higher grade of signal intensity on globus pallidus showed higher rate of neurologic abnormality (p<0.05) Especially postural instability and gait without associated arm movement were prominent findings. These bindings suggest that high signal intensity on brain MRI might be associated with a prodromal sign of manganese intoxication. Careful neurologic examination should be tool lowed up on welders showing high signal intensity in the golbus pallidus of brain MRI.

BACKGROUND: Apoptosis protease activating factor-1 (Apaf-1), caspase-9, Bcl-2, p53, and survivin are important factors in the pathway of apoptosis, but their clinicopathologic significance remains unclear in human cutaneous melanoma. We investigated the expression of these proteins and their clinical value in human cutaneous melanocytic lesions. METHODS: We performed an immunohistochemical analysis to examine the expression and distribution of Apaf-1, caspase-9, Bcl-2, p53, and survivin in 36 cases of malignant melanoma (22 cases of primary melanoma and 14 cases of metastatic melanoma) and 41 cases of melanocytic nevus. RESULTS: The expression of p53 was significantly higher in malignant melanoma than in melanocytic nevus (p<0.01), however the expressions of Apaf-1 and caspase-9 were significantly lower in malignant melanoma compared with melanocytic nevus (p<0.01 and p=0.027, respectively). Also, there was a significant difference for Bcl-2 staining between primary melanomas and metastatic lesions (p=0.004). Nuclear staining for survivin were absent in nevus, but were positive in 14 of 36 melanomas (p<0.01). CONCLUSIONS: The altered expression of Apaf-1, caspase-9, p53, and survivin are considered to be related to malignant progression in human cutaneous melanocytic lesions. Loss of Bcl-2 can be considered as a prognostic marker of malignant melanomas.

PURPOSE: To evaluate the magnetic resonance imaging (MRI) and clinicopathological features of triple negative breast cancer, and compare them with those of non-triple negative breast cancer. MATERIALS AND METHODS: This study included 231 pathologically confirmed breast cancers from January 2007 to May 2008. We retrospectively reviewed the MRI findings according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon: mass or non-mass type, mass shape, mass margin, non-mass distribution, and enhancement pattern. Histologic type, histologic grade, and the results for epidermal growth factor receptor, p53, and Ki 67 were reviewed. RESULTS: Of 231 patients, 43(18.6%) were triple negative breast cancer. Forty triple negative breast cancers (93.0%) were mass-type lesion on MRI. A round or oval or lobular shape (p=0.006) and rim enhancement (p=0.004) were significantly more in triple negative breast cancer than non-triple negative breast cancer. In contrast, irregular shape (p=0.006) and spiculated margins (p=0.032) were significantly more in non-triple negative breast cancer. Old age (p=0.019), high histologic grade (p<0.0001), EGFR positivity (p<0.0001), p53 overexpression (p=0.038), and Ki 67 expression (<0.0001) were significantly associated with the triple negative breast cancer. CONCLUSION: MRI finding may be helpful for differentiation between triple negative and non-triple negative breast cancer.
