Background : The goal of this study was to examine the health behaviors of nurses and provide basic information on health promotion for nurses. Materials and Methods : A self-administered questionnaire survey was completed by 340 nurses working at a university hospital in Daegu, Korea from March 6 to March 30, 2006. The questionnaire included demographic characteristics, working environment, health behaviors, self-assessed health status, and the practice of health promotion activities according to the work group(shift group vs. non-shift group). Results : There were significant differences in 'regular diet', 'drinking', 'ordinary health management', 'regular exercise', 'leisure activities', 'rest', and 'feeling of fatigue' between the two groups. The score for the practice of health promotion activities of the non-shift group was 121.9, which was higher than the 115.4 for the shift group. By field of practice of health promotion activities, there were significant differences in 'self-realization' and 'nutrition' between the two groups. Conclusion : The shift group did not appear to have enough time to take care of their health. It is therefore important to provide a working environment in which nurses are encouraged to increase their interest and efforts to maintain healthy behaviors. In addition, programs for education and training should be developed to help nurses adopt healthy life styles and enhance their self-esteem.
Background: This study examined the influence of body mass index (BMI), subjective body perception (SBP), and the differences between BMI and SBP influence on smoking among women. Methods: This study used the Korea National Health and Nutrition Examination Survey IV-2, 3 2008-2009. A urinary cotinine test was administered to 5485 women at least 19 years of age. Individuals whose cotinine level was at least 50 ng/mL were categorized as smokers. A multiple logistic regression analysis was performed to estimate the extent to which body-related variables affect female smoking. Results: Women with a lower BMI who perceived themselves to be normal or very fat were 2.09 times (1.14-3.83) more likely to smoke than women with a normal BMI and SBP. Women who were never married with a low BMI and thin SBP were 3.11 times (1.47-6.55) more likely to smoke than women with a normal BMI and SBP. Married women with a high BMI who considered themselves very fat were 0.63 times (0.43-0.94) less likely to smoke than women with a normal BMI and SBP. In contrast, divorced and widowed women with a low or normal BMI who considered themselves very fat were 26.1 times (1.35-507.3) more likely to smoke. Conclusions: Discrepancies between the objective physical condition (BMI) and the subjective body image (SBP) influence the female smoking rate. To reduce the number of female smokers, public education on the association between smoking behavior and weight issues is needed, especially among women with low BMI and distorted weight perception.
The purpose of this descriptive study was to identify the homecare needs of patients with cancer and to provide a basis of interventions. One hundred and two patients at one general hospital in Gyeongnam responded to a questionnaire developed on the basis of care needs perceived by nurses caring for hospitalized patients with cancer. The questionnaire was a Likert type 5 point scale with 56 items on five need categories ; 1) informational 2) physical care : 3) emotional care 4) socioeconomic care and 5) special care needs. Internal consistency of this questionnaire was Cronbach's $\alpha$=.9101 for total items. The data was collected from March 1st to May 31th, 1998, by two graduate nurses. In the data analysis, mean & standard deviation were calculated to identify the degree of care need of each item, and the t-test & ANOVA were done to determine the effects of patients' demographic background on their care needs. The findings are summarized as follows ; 1) The mean score of total of need items was 3.048. Of the four need categories the highest score was informational at 3.4, followed by emotional care, 3.063, physical care, 2.623, and socioeconomic care, 2.599. 2) In the informational need category there were four subcategories with 19 items. Medication and pain control had the highest score, 3.755 ; second was diet and exercise, 3.613 ; third was disease and treatment process, 3.337 ; and last was personal hygiene and infection prevention at 2.687. 3) In the physical care need category there was nine items, IV infusion for nutrition and management of treatment complication was above 3.2 points and the remaining items were in the 2.847-2.070 score ranges. 4) In the emotional care need category there were seven items. The highest need was in support for relationships with health personnel, 3.673. The need for support of religions beliefs and support for having a religion were low at about 2 points. 5) In the socioeconomic care need category there were six items. Support for medical insurance expansion and financial support were above 3 points. Legal support and support for caring of children were low in the care needs. 6) In the special care need category the there were 15 items. Informational need about immunization and informational need about effects of disease on growth and development were high, above 4.1 points. Need for decubitus care and prevention, sitz bath and incontinence care were low, below 2 points. 7) There were significant differences in degree of care need according to admission rate, education level, marital status, religion and caregiver's religion. In conclusion, homecare needs perceived by hospitalized patient's with cancer was moderate, but informational need was higher than direct care need, leading to the conclusion that the provision of sufficient information to patients with cancer at discharge is needed. Nursing interventions should be developed considering the patient's background.

Delirium is among the most common mental disorders encountered in patients with a temporary cognitive impairment such as consciousness disorder, attention disorder, and poor speech, particularly among those who are older. Delirium is distressing for patients and families, can interfere with the management of symptoms such as pain, and is associated with increased elderly mortality. The purpose of this paper is to generate useful clinical knowledge that can be used to distinguish the outcomes of patients with delirium in long-term care facilities. For this purpose, we extracted the clinical classification knowledge associated with delirium using a local covering rule acquisition approach with the rough lower approximation region. The clinical applicability of the proposed method was verified using data collected from a prospective cohort study. From the results of this study, we found six useful clinical pieces of evidence that the duration of delirium could more than 12 days. Also, we confirmed eight factors such as BMI, Charlson Comorbidity Index, hospitalization path, nutrition deficiency, infection, sleep disturbance, bed scores, and diaper use are important in distinguishing the outcomes of delirium patients. The classification performance of the proposed method was verified by comparison with three benchmarking models, ANN, SVM with RBF kernel, and Random Forest, using a statistical five-fold cross-validation method. The proposed method showed an improved average performance of 0.6% and 2.7% in both accuracy and AUC criteria when compared with the SVM model with the highest classification performance of the three models respectively.
In all mammalian species, progesterone is essential to both the preparation for, and maintenance of, pregnancy. The $20{\alpha}$-hydroxysteroid dehydrogenase ($20{\alpha}$-HSD) enzyme predominantly converts progesterone into its biologically inactive form $20{\alpha}$-hydroxyprogesterone, thereby regulating its activity. Thus, to directly assess sexual maturation in the MediKinetics $micropig^{(R)}$, we analyzed the concentration of the steroid hormones progesterone and estradiol during the estrous cycle. Our results show that the progesterone level exhibited by the analyzed $micorpig^{(R)}$ was low at the beginning of the estrous cycle, and then abruptly increased to $30.32{\pm}10.0ng/mL$ and $46.37{\pm}11.0ng/mL$ by days 9 and 11 of the cycle, respectively. It reached the highest level $55.87{\pm}3.5ng/mL$ on day 13 of the estrous cycle, before decreasing to $46.58{\pm}13.1ng/mL$ and $10.0{\pm}7.6ng/mL$ by days 15 and 17 of the cycle, respectively. In contrast, the estradiol level was shown to be highest ($27.13{\pm}11.2ng/mL$) at the initiation of the estrous cycle, after which point it decreased to $13.29{\pm}6.5ng/mL$ and $10.94{\pm}5.9ng/mL$ by days 4 and 5 of the estrous cycle, respectively. By day 17 of the estrous cycle, the estradiol level decreased to $4.13{\pm}7.6ng/mL$. We anticipate that these results will provide useful information to enable the study of human ovulation and reproductive physiology using the MediKinetics $micoripig^{(R)}$ as a model system. We recommend further investigation to elucidate the functional mechanisms underlying the regulation of sexual maturation in the MediKinetics $micropig^{(R)}$.
In this study, we compared nutrient content emphasized on labelling of processed milks with that of whole milks and evaluated how well they conform to labelling standard. A total of 98 samples (33 whole milks, 28 calcium fortified milks, 30 low-fat milks and 7 lactose hydrolyzed milks) were collected in hypermarkets in Seoul from August 28 to August 30 in 2012. Calcium, fat and lactose contents were tested in the samples. Calcium contents ranged 102.2~113.0 mg/100 mL in whole milks and 120.1~337.8 mg/100 mL in calcium fortified milks. The level of calcium contents in fortified milks ranged very broad. Accordingly, the standard of calcium contents on fortified milks will be required. Fat contents ranged 3.1~3.9 g/100 mL in whole milks and 0.1~1.9 g/100 mL in low-fat milks. The average of fats content in low-fat milks was nearly one third than whole milks. Lactose contents was ranged 4.6~5.1 g/100 mL in whole milks and not detected in lactose hydrolyzed milks. All of processed milks were suitable to processing standard and labelling standard. But nutrition claims often used on processed milk such as "High" or "Low" were not adequate to indicate the exact nutrient content, which is a cause of the confusion for milk product labelling to consumers. We need a lot of research about nutrient labelling that can deliver appropriate and understandable information to customers.
Food safety management should be based on scientific evidences. FAO and WHO presented risk analysis as one of four principles in food safety management. WTO also admits the self safety regulation only when it is made on the basis of risk assessment. Without scientific analysis, tracing and eliminating the cause of food poisoning is impossible. Research and development plays a key role to produce scientific evidences. The Korean government ran over 40 programs in 11 agencies from 2008 to 2010. However, there is no statistics on food safety R&D at present. In this research, food safety projects conducted from 2008 to 2010 are listed up by means of analysing National Science and Technology Information Service (NTIS). The analytical criteria are the name of programs, national standard classification of science and technology, and keywords. As result, Korea Food and Drug Administration, Ministry for Food, Agriculture, Forestry and Fisheries, and Rural Development Administration play major role in the food safety R&D. The portion of more than one year projects should rise up in order to achieve the data for risk assessment, which is strongly required to improve. Besides, the research should be deeper so as to publish more SCI papers. The R&D portfolio should be changed in direction to raise up the portion of biological hazards such as norovirus. In order to do so, a large number of food safety programs should be emerged. The categories of food safety management and the hygiene/quality management of the agricultural and livestock products in the national standard classification of science and technology should be emerged because they are set up reflecting agencies' interests in spite of few differences between them.
Objective : To estimate the socioeconomic costs of obesity in Korea,1998. Methods : The 1998 National Health and Nutrition Examination Survey(1998 NHNES) data was used and 10,880 persons who had taken health examinations were selected for study. Essential hypertension, NIDDM(non insulin-dependent diabetes mellitus), dyslipidemia, osteoarthritis, coronary heart disease, stroke were included as obesity related disease. The data of direct costs of obesity was obtained from the National Federation of Medical Insurance. The category of indirect costs was the loss of productivity caused by premature death and admission, time costs, traffic costs, nursing fees due to obesity. Multiple logistic regression model was developed to estimate prevalence odds ratio by obesity class adjusted demographic and socio-ecnomic factors and calculate PAF(Population Attributable Fraction) of obesity on obesity related disease. And we finally calculated the socioeconomic costs of obesity in relation to BMI with PAF. Results : The direct costs of obesity were 2,126 billion${\sim}965$ billion Won in considering out of pocket payment to uninsured services, and the indirect costs of obesity were 2,099 billion${\sim}1,086$ billion Won. Consequently, in considering out of pocket payment to uninsured services, the socioeconomic costs of obesity were 4.225 billion${\sim}2,050$ billion Won, which corresponded to about $0.094%{\sim}0.046%$ of GDP and $1.88%{\sim}0.91$ of total health care costs in Korea. Conclusions : Obesity represents a major health problem with significant economic implications for the society. This results are conservative estimates as far as all obesity related disease and all health care and indirect costs were not included due to missing information. further studies are needed to caculate socioeconomic costs of obesity more exactly.

Use of raw feedstuffs for livestock is limited by low digestibility. Recently, fermentation of feedstuffs has been highlighted as a new way to improve nutrient absorption through the production of organic acids using inoculated microorganisms, which can also play a probiotic role. However, standard procedures for feedstuff fermentation have not been clearly defined because the process is influenced by climatic variation, and an analytical standard for fermented feedstuffs is lacking. This study aimed to evaluate the microbiological and biochemical changes of feedstuffs during fermentation at temperatures corresponding to different seasons (10℃, 20℃, 30℃, and 40℃). We also investigated the effects of yeast, lactic acid bacteria (LAB), and Bacillus spp. on fermentation and determined the results of their interactions during fermentation. The viable cells were observed within 8 days in single-strain fermentation. However, when feedstuffs were inoculated with a culture of mixed strains, LAB were predominant at low temperatures (10℃ and 20℃), while Bacillus spp. was predominant at high temperatures (30℃ and 40℃). A significant drop in pH from 6.5 to 4.3 was observed when LAB was the dominant strain in the culture, which correlated with the concentrations of lactic acid. Slight ethanol production was detected above 20℃ regardless of the incubation temperature, suggesting active metabolism of yeast, despite this organism making up a marginal portion of the microbes in the mixed culture. These results suggested that fermentation temperature significantly affects microbiological profiles and biochemical parameters, such as pH and the lactic acid concentration, of fermented feedstuffs. Our data provide valuable information for the determination of industrial standards for fermented feedstuffs.
This study describes cross-contamination events that occur in animal food processing. We analyzed the number of Salmonella spp. contamination transferred from pork meat to workers' hands (wearing polyethylene gloves; PG, cotton gloves; CG, and bare hands), cutting boards and knives, and vice versa. Transfer rate of CG 38.80% was higher than that of PG 3.11% and bare hands 1.35%. In particular, when wearing CG, the transfer rate from the CG to bare hands with CG was 0.07%. Also, the range of transfer rates from the contaminated pork meat to cutting board and knife was 0.20-1.99%. In contrast, the transfer rates from the worker's hands (with PG/CG and bare hands) to cutting board, knife, and pork meat ranged from 0.0015-0.21%. There was a lower transfer rate from workers' hands than from pork meat. These findings indicate that the use of PG compared with CG could effectively reduce or prevent the cross-contamination and provide important information concerning the consecutive transfer of Salmonella spp. during food processing.
