The teaching laboratory is the central place to teach lab courses to undergraduate students. It is thus critical to evaluate how lab skills of students will be affected by the management of this lab. This study attempts to introduce the 6S concept, referring to "Seiri", "Seiton", "Seiso", "Seiketsu", "Shisuke", and "Safety", to the management of teaching laboratory, in particular, to the management of environments, safety, item deposition, reagents and consumables in the laboratory. We find that applying the "6S" management maintains a tidy lab environment, facilitates teaching the lab skills, and improves the quality of teaching, which together achieves the goal of education with the atmosphere. This study can provide a guideline for establishing and managing teaching laboratories in universities.

OBJECTIVES: This research was conducted to identify the consumers' food choice factors that affect the consumers' replacement of soft drinks with carbonated water. METHODS: The present study used secondary data from a consumer panel survey conducted by the Rural Development Administration of Korea, and the data included the panel members' purchase records based on their monthly spending receipts. The survey asked the participants about their food choice factors and their personal responsibility for their health. This survey included independent variables for the consumers' food purchase factors. As a dependent variable, two types of groups were defined. The replacement group included those people who increased their purchase of carbonated water and decreased their purchase of soft drinks. The non-replacement group included those people who did not change their purchase patterns or they increased their purchase of soft drinks and they decreased their purchase of carbonated water. Logistic regression analysis was conducted to determine the consumers' food choice factors that were associated with replacing soft drinks with carbonated water. RESULTS: The replacement group was significantly associated with (1) a younger age (OR=0.953), (2) being a housewife (OR=2.03), (3) higher income (OR=1.001) and (4) less concern about price (OR=0.819) when purchasing food. This group also showed (5) higher enjoyment (OR=1.328) when choosing food and (6) they took greater responsibly for their personal health (OR=1.233). CONCLUSIONS: This research is the first study to mainly focus on soft drinks and carbonated water. The result of this research showed that young, health-conscious consumers with a higher income and who are more interested in food have more possibilities to replace soft drinks with carbonated water. These research findings may be applied to consumers who have characteristics that are similar to the young health-conscious consumers and the results can help to suggest ways to reduce sugar intake and improve public health. However, this research has a limitation due to the application of secondary data. Therefore, a future study is needed to develop detailed survey questions about food choice factors and to extend these factors to all beverages, including soft drinks made with sugar substitutes, so as to reflect the growth of alternative industries that use artificial sweeteners or different types of sugar to make commercially available drinks.

OBJECTIVE: The aim of this study is to assess the prevalence and determinants of folic acid supplementation among women referred to community health centers. METHODS: This was a cross-sectional study conducted in 325 women referred to community health centers. The subjects were selected from 8 community health centers, using a stratified sampling technique. Data regarding demographics, socioeconomic status, obstetrics, folic acid supplementation status, and household food security status were obtained via questionnaires. The data was analyzed in SPSS v22. RESULTS: The prevalence of folic acid supplementation both before and during pregnancy was 54.5%. The results of the study showed that folic acid supplementation had a significant positive association with education level (odds ratio [OR],0 .441; 95% confidence interval [CI], 0.199–0.977; P<0.05), being employed (OR, 0.353; 95% CI, 0.148–0.840; P<0.05), and planned pregnancy (OR, 18.113; 95% CI, 7.371–44.51; P<0.001). However, other variables, including age, husband's age, husband's education and employment status, the number of prior pregnancies, economic satisfaction, and household food security, were nonsignificant factors affecting folic acid supplementation. CONCLUSION: Women with lower socioeconomic status are less likely to take folic acid supplements, and more effort should be made to increase their awareness of the importance of supplementation. Unplanned pregnancy is another strong risk factor for not supplementing with folic acid, and thus should be avoided.

PURPOSE: This study was a correlational research to examine the relationship between career plateau, career planning, social support and turnover intention experienced by nurses in the clinical nursing field. METHODS: Participants were 237 nurses working in general hospitals with 100~300 beds located in G Metropolitan City. Data were collected from September 26 to October 6, 2016, and analyzed using the SPSS/WIN 22.0 program. Descriptive statistics, independent t-test, univariate ANOVA, Scheffé test, correlation analysis, and hierarchical multiple regression analysis were conducted. RESULTS: Participants' turnover intention was positively correlated with career plateau (r=.38, p < .001), structural career plateau (r=.31, p < .001) and content plateau (r=.35, p < .001), but negatively correlated with social support (r=−.38, p < .001), supervisor support (r=−.36, p < .001), peer support (r=−.32, p < .001), and career planning (r=−.15, p=.043). Factors associated with participants' turnover intention were supervisor support (β=−.22, p=.006), structural career plateau (β=.19, p=.012), and content career plateau (β=.14, p=.047). CONCLUSION: Results suggest that structural career plateau, content career plateau, and supervisor support are related to nurses' turnover intention. To lower nurses' turnover intention, alternative ways must be developed to improve the structure of nursing organizations to address career plateau and establish an organizational culture that can be supported by supervisors.

OBJECTIVES: The Korean Food Composition Table (KFCT) was first published in 1970, and has since been updated every five years by the Rural Development Administration (RDA). This study was conducted to introduce the development strategies, features, and challenges of the 9th revision of the KFCT. METHODS: Due to the increasing demands of nutrient database users and generators, the RDA started a new research project in 2013 to improve the quantity and quality of data for the 9th revision of the KFCT. Over 1,000 food items frequently consumed in Korea were selected as key foods using the results of the Korean National Health and Nutrition Examination Survey. About 200 raw materials and processed food items were collected and analyzed every year. Target nutrients that were analyzed by collaborative labs, such as, sugars, selenium, iodine, and biotin, were increased from 22 to 43. Analytical sample handling procedures and data quality evaluation systems were also established in collaboration with 10 contracted labs. Data were evaluated for data quality according to the FAO/INFOODS, CODEX, and AOAC guidelines. RESULTS: The 9th revision contains data on 3,000 food items and up to 43 and 140 food nutrients for the printed table and the excel database file, respectively. Overall, 1,485 data items were newly added, 973 of which were provided by the RDA and 512 were cited from foreign nutrient databases. The remaining 1,515 food items were maintained as in the 8th revision. CONCLUSIONS: The KFCT provides the basic infrastructure for food and nutrition policy, research, and dietary practice in South Korea. The use of the KFCT has increased exponentially in the past few years in both public and private sectors; accordingly, increased efforts should be paid to the preparation, improvement, and maintenance of KFCT.

PURPOSE: The objective of this study was to develop a processed foods database (DB) for estimation of processed food intake in the Korean population using data from the Korea National Health and Nutrition Survey (KNHANES). METHODS: Analytical values of processed foods were collected from food composition tables of national institutions (Development Institute, Rural Development Administration), the US Department of Agriculture, and previously reported scientific journals. Missing or unavailable values were substituted, calculated, or imputed. The nutrient data covered 14 nutrients, including energy, protein, carbohydrates, fat, calcium, phosphorus, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C. The processed food DB covered a total of 4,858 food items used in the KNHANES. Each analytical value per food item was selected systematically based on the priority criteria of data sources. RESULTS: Level 0 DB was developed based on a list of 8,785 registered processed foods with recipes of ready-to-eat processed foods, one food composition table published by the national institution, and nutrition facts obtained directly from manufacturers or indirectly via web search. Level 1 DB included information of 14 nutrients, and missing or unavailable values were substituted, calculated, or imputed at level 2. Level 3 DB evaluated the newly constructed nutrient DB for processed foods using the 2013 KNHANES. Mean intakes of total food and processed food were 1,551.4 g (males 1,761.8 g, females 1,340.8 g) and 129.4 g (males 169.9 g, females 88.8 g), respectively. Processed foods contributed to nutrient intakes from 5.0% (fiber) to 12.3% (protein) in the Korean population. CONCLUSION: The newly developed nutrient DB for processed foods contributes to accurate estimation of nutrient intakes in the Korean population. Consistent and regular update and quality control of the DB is needed to obtain accurate estimation of usual intakes using data from the KNHANES.

PURPOSE: This study was conducted to evaluate the association between AR and mental health status in the general Korean adult population and to investigate the relative burden of AR on mental health using the Allergic Rhinitis and Its Impact on Asthma (ARIA) classification. METHODS: A cross-sectional study was performed by using data from 11,154 individuals, 19 years old or older in the Korean National Health and Nutrition Examination Survey 2011-2012. Univariate analysis was conducted in the healthy AR groups with weighted prevalence of demographic characteristics, socioeconomic status, and comorbid diseases. Subanalysis that classified AR severity according to the ARIA classification was carried out to evaluate the relationship of AR severity with mental health. The odds ratios (ORs) for each component representing mental health status were estimated by multiple logistic regression analysis with confounder adjustment. RESULTS: Univariate analysis with the chi-square test after adjustment for age, sex, body mass index, smoking status, alcohol use status, and exercise status, components representing mental health status showed a linear relationship with the severity of AR according to the ARIA classification. Stress, depressive mood, suicidal thoughts, and psychological consultation factors were correlated with AR after adjustment for demographic characteristics and socioeconomic status. Even after adjustment for comorbid allergic diseases, the correlation remained significant with stress, depressive mood, and psychological consultation factors (OR [95% CI]; 1.227 [1.042, 1.445], 1.368 [1.095, 1.71], 1.804 [1.096, 2.969], respectively). CONCLUSIONS: Patients with AR appear to be at higher risk of mental disorders in the general Korean adult population. Moreover, persistent or severe AR was correlated with poor mental health. Therefore, better control of AR may be conducive to better mental health, and more attention should be paid to the psychological status of AR patients.
