  • The main sources of energy consumption in warehouses are MHE(Material Handling Equipment), HVAC(Heating, Ventilating and Air Conditioning) and Lighting. Warehouses in advanced countries raise energy efficiencies with energy consumption diagnosis, technology development and systematic management and improvements for MHE, HVAC and Illuminating, etc. They have managed illuminating system, air conditioning, motor driven system, air circulation method, dock facility, layout, AS/RS, conveyor system and battery management, etc. Ansong Pyeongtaek area investigation resulted that 43.9[%] of enterprises are managing partly energy consumption source. But the data resulted with not substantial management of energy consumption but passive management for only electric bill curtailment. Therefore through survey research & visiting interviews of some companies in Ansong Pyeongtaek area, we understood the status of energy consumption source management and proposed energy efficiency methods on the basis of that results.

  • The purposes of this study were to explain consumer attitude and purchasing behavior, and coping strategy considering consumption emotions of technology and individual characteristics associated with high-tech products. The results of this study were as follows: consumer attitude was found to be somewhat favorable and a half of the respondents had some purchasing experience of high-tech products. Many consumers were more likely to perceive consumption emotion and some of coping strategies were found to be preferred to others. Then consumer attitude was found to be significantly influenced by some of the consumption emotion, while other individual characteristics were found to be insignificant. In addition, the purchasing experience was found to be significantly influenced by consumer attitude, marital status and education. Finally, each kind of consumption emotion might have a relation to several coping strategies.

  • Purpose: This study aimed to investigate the status of caffeine-containing energy drink consumption among Korean nursing students and to identify associated psychological factors. Methods: In total, 187 Korean nursing students participated in this cross-sectional study. A self-administered questionnaire was used to identify participants' general characteristics and psychosocial factors (self-esteem, academic stress, depression, and college adjustment) associated with energy drink consumption. Data were analyzed with SPSS using descriptive statistics, the $x^2$ test, the t-test, and logistic regression. Results: More than two-thirds (73.3%) of the participants had consumed energy drinks. Among the investigated psychological factors, depression appeared to most strongly influence energy drink consumption behaviors in this population. Conclusion: The consumption of caffeine-containing energy drinks was found to be common among nursing students preparing to become health care professionals; depressed nursing students were more likely to have consumed energy drinks than non-depressed students. Nursing educators should emphasize the early detection of unhealthy beverage consumption habits and provide appropriate education to enhance healthy behaviors in future health care professionals.

  • Objectives: The purpose of this study was to shed further light on the effect of modifiable health behavior risk factors on dependence in activities of daily living, defined in a multidimensional fashion. Methods: The study participants were 10,278 middle aged Americans in a longitudinal health study, the Health and Retirement Survey (HRS). A multi-stage probability sampling design incorporating the effect of population sizes (Metropolitan and non-metropolitan), ethnicity (the non- Hispanic White, the Hispanic, and the Black), and age (age 51-61) was utilized. Basic Activities of Daily Living (ADL) were measured using five activities necessary for survival (impairment in dressing, eating, bathing, sleeping, and moving across indoor spaces). Explanatory variables were four health behavior risk factors included smoking, exercise, Body Mass Index (BMI), and alcohol consumption. Results: Most participants at baseline were ADL independent (1992). 97.8% of participants were independent in all ADL's at baseline and 78.2% were married. Approximately 27.5% were current smokers at baseline, and the subjects reported moderate or heavy exercise were 74.8%. All demographic characteristics and behavioral risk factors were significantly associated with the ADL status at Wave 4 except alcohol consumption. Risk behaviors such as current smoking, sedentary life style and high BMI at Wave 1 were associated with ADL status deterioration; however, moderate alcohol consumption tended to be more related to better ADL status than abstaining at Wave 4. ADL status at Wave 1 was the strongest factor and the next was exercise and smoking affecting ADL status at Wave 4. People who were in ADL dependent at Wave 1 were 15.17 times more likely to be ADL dependent at Wave 4 than people who were in ADL independent at Wave 1. Concerning smoking cigarettes, people who kept only light exercise or sedentary life style at Wave 1 were 1.70 times more likely to be died at Wave 4 than the people who did not smoke at Wave 1. Conclusions: All demographics and health behaviors at wave 1 had consistently similar OR trends for ADL status to each other except alcohol consumption. Smoking and exercise in health behaviors, and age and gender in demographics at Wave 1 were significant factors associated with ADL group separation at Wave 4.

  • Background: The incidence and etiology of facial bone fracture differ widely according to time and geographic setting. Because of this, prevention and management of facial bone fracture requires ongoing research. This study examines the relationship between socioeconomic status and the incidence of facial bone fractures in patients who had been admitted for facial bone fractures. Methods: A retrospective study was performed for all patients admitted for facial bone fracture at the National Medical Center (Seoul, Korea) from 2010 to 2014. We sought correlations amongst age, gender, fracture type, injury mechanism, alcohol consumption, and type of medical insurance. Results: Out of the 303 patients meeting inclusion criteria, 214 (70.6%) patients were enrolled in National Health Insurance (NHI), 46 (15.2%) patients had Medical Aid, and 43 (14.2%) patients were homeless. The main causes of facial bone fractures were accidental trauma (51.4%), physical altercation (23.1%), and traffic accident (14.2%). On Pearson's chi-square test, alcohol consumption was correlated significantly with accidental trauma (p<0.05). And, the ratio of alcohol consumption leading to facial bone fractures differed significantly in the homeless group compared to the NHI group and the Medical Aid group (p<0.05). Conclusion: We found a significant inverse correlation between economic status and the incidence of facial bone fractures caused by alcohol consumption. Our findings indicate that more elaborate guidelines and prevention programs are needed for socioeconomically marginalized populations.

  • The aim of this study was to evaluate the status of consumption and consumer satisfaction of dietary fiber supplements. The survey was conducted using a self-recorded questionnaire developed to meet the purpose of this study. The characteristics of the subjects who have taken dietary fiber supplements in the past are as follows: distributions of socioeconomic variables showed that the highest-ranked group(the group that reported the highest consumption of dietary fiber supplements) was professionals with a college degree or higher degree. In addition, the highest-ranked group were the most healthy, nonsmokers and reported drinking habits of '1~2 times/week'. Regarding the health status of those surveyed, digestive disease and constipation were the most common complaints. The majority responded with 'health concerns' to the question that asked the reason for their purchase of the dietary fiber supplements. Three major places respondents could find dietary fiber supplements were 'through the internet', 'the market', 'the pharmacy' in descending order. The compositions of dietary fiber products varied. 'konjac', 'cellulose', 'psyllium husks' were the most popular components consumed by the subjects. The average duration of product consumption was less than one month. In terms of satisfaction levels(satisfaction was ranked from 1 to 5), 'taste' and 'type' scored the highest in satisfaction levels while 'price' ranked the lowest. When subjects were asked about self-awareness regarding the physiological efficacy of dietary fiber supplements, the responses were positive in 'bowel movement' and 'weight loss'. Further research is required to improve the quality of dietary fiber supplements in order to assist consumers in selecting the appropriate products.

  • Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

  • The pale, soft, exudative (PSE) syndrome lowers storage quality and consumers acceptability in the particular meat. With the increase in the consumption of parted chickens in Korean meat consumption trade, a parallel increase in the concern over the PSE status of chickens have been noticed. The present study focused on the PSE status of broiler's breast to investigate the effects of different degrees of PSE on its quality and storage characteristics. A total of 46 broiler chickens of 35 days old averaging 1,251-1,350 g were selected for the study. Breast separated and skin was removed. The breast meat was stored at $4^{\circ}C$ for 3 days and were analysed for pH, lightness, yellowness, redness, shear force, water-holding capacity (WHC), cooking loss, Thiobarbituric acid reactive substances (TBARS) and Volatile basic nitrogen (VBN) on day 1 and 3 during the storage. Increase in the degree of broilers breast PSE during storage caused fall in pH and shear force and increase in lightness, cooking loss, TBARS, VBN. Broilers breast PSE status confirms the actual pale soft and exudative nature of meat.
