Yam has been recognized as healthy food due to its various biological activities, such as anti-obesity, antimicrobial, anticancer and immune-stimulation activities. In this study, antibacterial activities of 800 more natural plant extracts against yam-putrefactive psychrotrophic bacterium, Pseudomonas rhodesiae YAM-12, were evaluated to select a natural preservative, which is useful to long-term storage of yam and fresh-cut production. Finally, the clove oil was selected, and applied for the production of yam fresh-cut. The 1% of clove oil treated fresh-cut showed minor color changes during 31 days storage at $4^{\circ}C$ and the microbial growth was not detected. When the artificially contaminated fresh cut by dipping with P. rhodesiae YAM-12 suspension for 3 min was treated 1% clove oil, the microbial growth was identified to $10^4$ CFU/g from $10^3$ CFU/g with minor color changes. Whereas, treatment of sterilized water, or 100 ppm NaOCl into artificially contaminated fresh cut showed severe putrefaction $(10^8\;CFU/g)$ and color changes. Considering the previous reports that clove oil has antimicrobial, antioxidation, and antithrombosis activity, the use of clove oil into the yam fresh cut will provide market safety and consumer acceptability by prevention of microbial putrefaction and its biological activity.

This study aimed to investigate the levels of Obstructive Sleep Apnea (OSA), health behavior and sleep quality and to examine the predictors of OSA in patients with ischemic cardio-cerebrovascular disease. 141 patients who were admitted to the vascular unit were recruited and surveyed using structured questionnaires. Saturation of Peripheral Oxygen (SpO2) was measured at three time points using a pulse oximeter. Data were analyzed using SPSS/WIN 20.0. The mean age of the subjects was $64.4{\pm}11.1$ years and 61% was men. The 21.3%(n=30) of the subjects were classified as high-risk for OSA by the cut point and 71.6%(n=101) had low sleep quality. OSA high-risk group showed significant difference in SpO2 in the middle of sleep (p=.006) and at the end of sleep (p=.004) compared to the low-risk group. Multiple logistic regression analysis showed that perceived frequent snoring, smoking, obesity, lack of exercise among health behavior were found as predicting factors on OSA. OSA or persistent snoring should be recognized as a cardiovascular risk factor in the cardiovascular nursing practice. In addition to early treatment of OSA, education and counseling should be provided to patients and their family for prevention of secondary recurrence.

Purpose: Recently, complementary and alternative medicine (CAM) has been increasingly used in children. Studies have shown that 34% of adults and 11% of children use CAM in the USA and Canada. The purpose of this study was to investigate the prevalence and patterns of CAM use in elementary children in Korea. Methods:From July to August 2007, parents of elementary children completed a questionnaire survey at Gwang-ju. In all, 794 questionnaires were analyzed. Results:Of the 794 respondents, 278 answered that their pupils (35%) had experienced CAM. The following types of CAM therapy were used: herbal medicine, 62.5% dietary supplements, 31.2% vitamins, 30.2% and acupuncture, 11.1%. CAM therapies were used for the following diseases: nutritional deficiency, 33.3% atopic dermatitis, 31.3% arthralgia, 31.3% allergic rhinitis, 28.8% obesity, 26.3% and asthma. The following were the motives to use CAM: prevention of diseases (33.5%), dissatisfaction with modern medicine (21.2%), and complementary therapy to modern medicine (20.5%). People gained information about CAM through neighbors (65%) and mass media (21%). Moreover, 83 parents (30%) were satisfied with CAM because of its effectiveness. Conclusion:Many parents have advocated the use of CAM in their children. However, most of them used CAM without any prescription or adequate knowledge. Further studies are required to determine the efficacy of CAM.

As chronic diseases have become more prevalent and problematic, effective cares for major chronic diseases have been a locus of the healthcare policy. In this regard, this study examines how region-specific characteristics affect the prevalence of hypertension in South Korea. To analyze, we combined a unique multi-year data set including key indicators of health conditions and health behaviors at the 237 small administrative districts. The data are collected from the Annual Community Health Survey between 2009 and 2011 by Korea Centers for Disease Control and Prevention and other government organizations. For the purpose of investigating regional variations, we estimated using Geographically Weighted Regression (GWR) and decision tree model. Our finding first suggests that using the multi-year data is more legitimate than using the single-year data for the geographical analysis of chronic diseases, because the significant annual differences are observed in most variables. We also find that the prevalence of hypertension is more likely to be positively associated with the prevalence of diabetes and obesity but to be negatively associated with population density. More importantly, noticeable geographical variations in these factors are observed according to the results from the GWR. In line with this result, additional findings from the decision tree model suggest that primary influential factors that affect the hypertension prevalence are indeed heterogeneous across regional groups. Taken as a whole, accounting for geographical variations of health conditions, health behaviors and other socioeconomic factors is very important when the regionally customized healthcare policy is implemented to mitigate the hypertension prevalence. In short, our study sheds light on possible ways to manage the chronic diseases for policy makers in the local government.

Purpose: The purpose of this study was to examine the relationship among the levels of total serum cholesterol level, blood pressure, body mass index, and lifestyle. Method: This study was designed as a descriptive correlation study. Subjects were 972 adults participated voluntarily living in GyeongNam. The height, weight, blood pressure and fasting serum cholesterol were measured. Body mass index was caculated. Information on general characteristics (age, gender, education, job, family history) and life style(cigarette, alchol, sleeping time, regular exercise, meal pattern, peppery, salty, sweetness, vegetable diet, meat diet) were collected using a questionnaire by interviewing method. Result: The mean value of total serum cholesterol was $197{\pm}36.4mg/dl$(mean; $189{\pm}36.7mg/dl$, women; $202{\pm}35.1mg/dl$). By simple analysis, the serum total cholesterol according to general characteristics features was statistically significant in age(F= 6.765, p=000) and gender (t=5.372, p=.000). Total serum cholesterol levels increased significantly with increasing BMI. The serum total cholesterol according to life style features was statistically significant in cigarette(${\chi}^2=12.12$, p=.016), exercise(${\chi}^2=6.335$, p=.042), salty taste(${\chi}^2=18.801$, p=016), vegetable diet (${\chi}^2=19.488$, p=012). The most affecting factor which total serum cholesterol factor was BMI(${\beta}=.151$, p=.000). Conclusion: The significant risk factors relating to serum total cholesterol were age, gender, BMI, smoking, and exercise. Therefore, for the reduction of serum total cholesterol level, it is recommended that nursing intervention for the prevention of obesity, change of life style should be implemented.

The aim of this study was to investigate the latent classes and predictors of chronic diseases such as hypertension, dyslipidemia, arthritis, thyroid disease, depression, atopy, allergy, and diabetes. The subjects of this study were Korean citizens who participated in the Korea National Health and Nutrition Examination Survey in 2014. Stratified cluster sampling method was used with a sample size of 7,550. Latent hierarchy analysis was applied to this data. Four classes were identified. Class 1 consisted of participants with hypertension and diabetes. Class 2 consisted of participants with atopy and allergies. Class 3 consisted of participants with dyslipidemia, arthritis, thyroid disease, and depression. Class 4 consisted of participants without any chronic diseases. In comparing Class 1 to Class 4, age, physical activity, self-management, obesity, and presence of high cholesterol were found to be significant. In comparing Class 2 to Class 4, gender, age, and education level were significant. When Class 3 was compared to Class 4, gender, age, pain and discomfort, as well as high cholesterol were found to be significant. Diabetes and hypertension should be treated as comorbid conditions, applying integrated treatments involving effective drug treatment, diet, and physical activity programs. Atopy was found to be strongly correlated with allergies. Thyroid disease was found to coexist with dyslipidemia and arthritis, along with having a strong correlation to depression. Age-appropriate preventive measures can help reduce the risk of chronic diseases.

The purpose of this study was to determine the association of the Body Shape Index (ABSI) with suicide ideation and suicide attempts by controlling the body mass index (BMI), as well as general characteristics that may affect suicide. The study has used The Sixth Korea National Health and Nutrition Examination Survey conducted by the Korea Centers for Disease Control and Prevention from 2013 to 2015. A total of 13,155 participants were studied, excluding those who had no information on variables that could affect suicidal ideations and suicidal attempts. The chi-squared test and the multivariate logistic regression analysis were performed. The results of the analysis showed that those who had obesity in BMI were more likely to commit suicide and suicide than those who were in 'standard' in BMI. In ABSI, Q3 group was more likely to commit suicide than Q1 group. The number of suicide attempt was significantly higher in the group with Q3 in ABSI than in Q1 group (3.623 times (95% CI 1.027-12.772)). The results of this study suggest that a higher ABSI compared to BMI means that it is possible to make a more extreme choice of suicide attempt rather than suicide ideation.

Background: Omega-3 long-chain (${\geq}C_{20}$) polyunsaturated fatty acids (${\omega}3$ LC-PUFA) confer important attributes to health-conscious meat consumers due to the significant role they play in brain development, prevention of coronary heart disease, obesity and hypertension. In this study, the ${\omega}3$ LC-PUFA content of raw and cooked Longissimus thoracis et lumborum (LTL) muscle from genetically divergent Australian prime lambs supplemented with dietary degummed crude canola oil (DCCO) was evaluated. Methods: Samples of LTL muscle were sourced from 24 first cross ewe and wether lambs sired by Dorset, White Suffolk and Merino rams joined to Merino dams that were assigned to supplemental regimes of degummed crude canola oil (DCCO): a control diet at 0 mL/kg DM of DCCO (DCCOC); 25 mL/kg DM of DCCO (DCCOM) and 50 mL/kg DCCO (DCCOH). Lambs were individually housed and offered 1 kg/day/head for 42 days before being slaughtered. Samples for cooked analysis were prepared to a core temperature of $70^{\circ}C$ using conductive dry-heat. Results: Within raw meats: DCCOH supplemented lambs had significantly (P < 0.05) higher concentrations of eicosapentaenoic (EPA, $20:5{\omega}3$) and EPA + docosahexaenoic (DHA, $22:6{\omega}3$) acids than those supplemented with DCCOM or DCCOC; Dorset sired lambs contained significantly (P < 0.05) more EPA and EPA + DHA than other sire breeds; diet and sire breed interactions were significant (P < 0.05) in affecting EPA and EPA + DHA concentrations. In cooked meat, ${\omega}3$ LC-PUFA concentrations in DCCOM (32 mg/100 g), DCCOH (38 mg/100 g), Dorset (36 mg/100 g), White Suffolk (32 mg/100 g), ewes (32 mg/100 g) and wethers (33 mg/100 g), all exceeded the minimum content of 30 mg/100 g of edible cooked portion of EPA + DHA for Australian defined 'source' level ${\omega}3$ LC-PUFA classification. Conclusion: These results present that combinations of dietary degummed crude canola oil, sheep genetics and culinary preparation method can be used as effective management tools to deliver nutritionally improved ${\omega}3$ LC-PUFA lamb to meat consumers.

Objectives: The purpose of this study was to investigate whether chemical exposure among workers has relevance to dyspnea using data from the $3^{rd}$ Korea Working Conditions Survey. Methods: The research subjects were 29,711 wage workers. Chemical exposures consist of four factors, (1) breathing in vapors, fumes, dust and dirt, (2) breathing in organic solvent vapors, (3) handling or touching chemicals, and (4) secondhand smoke. Multiple logistic regression analysis was performed to examine the association between chemical exposure and dyspnea in the last 12months using proc surveylogistic in SAS 9.3 statistical software excluding people who had received a diagnosis of hypertension or obesity that can affect the respiratory distress symptoms(n=27,842). Results: Chemical exposure among workers was associated with dyspnea after adjustment for demographics and job characteristics. Prevalence of dyspnea was 4.9 per 1,000 among men and 5.8 per 1,000. Compared to a total score of 0 points of chemical exposure among workers, a total score of 1, 2-3, and 4 points tended to have increased risk of dyspnea in a dose-response manner for both men (OR=1.43, 1.93, and 4.26; P-for trend=0.002) and women(OR=1.10, 2.81, and 7.70; P-for trend=0.002). Stratified analysis by duration of current job showed that the association between chemical exposure and dyspnea tended to get stronger until 15 years and then disappeared afterwards, which reflects healthy worker survivor effect. Conclusions: We observed significant association between chemical exposure and dyspnea using the data of the $3^{rd}$ Korea Working Conditions Survey. Our results warrants providing knowledge related to chemical exposure, performing prevention activities, and creating various health policies to protect workers.

The causes of stroke are presumed hypertension, atherosclerosis,. cardiac disease, diabetes mellitus and old age and risk factors of stroke are suggested hypertension, hyperlipidemia. obesity, smoking and drinking etc. Especilly, hypertension is one of the most important cause and risk factor of stroke, therfore without therapy hypertension leads to stroke. The frequence of hypertension is significantly higher in hemorrhage patients of intracranial hemorrhage and subarachnoid hemorrhage. Antihypertensive therapy has an impact not only on the primary prevention of stroke but also on stroke recurrence and the declining of stroke motality has been attributed to the widespread availability and use of antihypertensive therapy. The goals of antihypertensive therapy decrease the complications and motalitv of cardiovascular system and prevent the promoting arteriosclerosis. In this study, we observed the blood pressure change of cb-hemorrhagic patients with hypertension who were hospitalized from 1996. 3. 1 to 1997. 2 .26 in Wonkwang Oriental Hospital. These patients had no antihypertensive therapy and were supplied herb med(Jaum sikpoongtang, Chungrijagamtang, Gojinumja) in medication. Our results suggested as follows. 1. Systolic and diastolic average BP at admission is $150.71{\pm}15.61mmHg$ and $95.00{\pm}8.8mmHg$ and this is hypertension state defining WHO 2. During one week in admission, the blood pressure demostrated a marked declination by SBP 8.97mmHg and DBP 6.22mmHg. 3. During two week in admission, the declination of SBP was significant in paired t-test(p<0.05) but, the declination of DBP was non-significant in paired t-test. 4. The blood pressure during third and fourth weeks gradually declined but, non-significant in test. According to the above results, we suggested that the BP declination Was affected by $Jamyang{\cdot}Jaum$ prescriptions in acute stage of cerebral hemorrhage.
