Background: Acute pyelonephritis (APN) is one of the most common community-acquired bacterial infections. Recent increases of antimicrobial resistance in urinary pathogens might have changed the other epidemiologic characteristics of APN. The objective of this study was to describe the current epidemiology of APN in Korea, using the entire population. Methods: From the claims database of the Health Insurance Review and Assessment Service in Korea, the patients with International Classification of Diseases, 10th Revision codes N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis during 2010-2014 were analyzed, with two or more claims during a 14-day period considered as a single episode. Results: The annual incidence rate of APN per 10,000 persons was 39.1 and was on the increase year to year (35.6 in 2010; 36.7 in 2011; 38.9 in 2012; 40.1 in 2013; 43.8 in 2014, P = 0.004). The increasing trend was observed in both inpatients (P = 0.014) and outpatients (P = 0.004); in both men (P = 0.042) and women (P = 0.003); and those aged under 55 years (P = 0.014) and 55 years or higher (P = 0.003). Eleven times more women were diagnosed and treated with APN than men (men vs. women, 6.5 vs. 71.3), and one of every 4.1 patients was hospitalized (inpatients vs. outpatients, 9.6 vs. 29.4). The recurrence rate was 15.8%, and the median duration from a sporadic episode (i.e., no episode in the preceding 12 months) to the first recurrence was 44 days. The recurrence probability increased with the number of previous recurrences. The average medical cost per inpatient episode was USD 1,144, which was 12.9 times higher than that per outpatient episode (USD 89). Conclusion: The epidemiology of APN in Korea has been changing with an increasing incidence rate.

Background: The Korea Risk Information Surveillance System (K-RISS) was developed to enable the early detection of food and drug safety-related issues. Its goal is to deliver real-time risk indicators generated from ongoing food and drug risk monitoring. However, the existing K-RISS system suffers under several limitations. Objectives: This study aims to augment K-RISS with more detailed indicators and establish a severity standard that takes into account structural changes in the daily time series of K-RISS values. Methods: First, a Delphi survey was conducted to derive the required weights. Second, a control chart, commonly used in statistical process controls, was utilized to detect outliers and establish caution, attention, and serious levels for K-RISS values. Furthermore, Bai and Perron's method was employed to determine structural changes in K-RISS time series. Results: The study incorporated 'closeness to life' and 'sustainability' indicators into K-RISS. It obtained the necessary weights through a survey of experts for integrating variables, combining indicators by data source, and aggregating sub K-RISS values. We defined caution, attention, and serious levels for both average and maximum values of daily K-RISS. Furthermore, when structural changes were detected, leading to significant variations in daily K-RISS values according to different periods, the study systematically verified these changes and derived respective severity levels for each period. Conclusions: This study enhances the existing K-RISS system and introduces more advanced indicators. K-RISS is now more comprehensively equipped to serve as a risk warning index. The study has paved the way for an objective determination of whether the food safety risk index surpasses predefined thresholds through the application of severity levels.

Objectives: The occurrence characteristics of BTEXS and phytoncides were investigated by type of urban forest. Methods: Four types of urban green space (Hongneung Forest, Mt. Chunjang, residential park, and traffic island) and Gwangneung Forest were selected. Monitoring of phytoncides and BTEXS was conducted considering the activity times of urban residents (five times per day) using a Tenax TA tube and suction pump in June 2017 (one day). Results: Phytoncide concentrations were ranked as Gwangneung Forest>Hongneung Forest>Mt. Cheonjang>traffic island>residential park. Relatively high concentrations of phytoncides were also identified in the urban forest. There was no significant difference between Gwangneung Forest and the urban forest. BTEXS concentrations were ranked as traffic island>residential park>Hongneung Forest>Gwangneung Forest>Mt. Cheonjang. Traffic island and residential park showed high levels of BTEXS depending on the inflow of vehicles. The difference in concentration by time was significant for the traffic island in particular. Pollutant levels in Hongneung Forest were as low as in Gwangneung Forest. Conclusion: The concentrations of phytoncides and BTEXS were different by types of urban green space, and the potential for health and hygiene of urban forests were able to be investigated. This study is expected to provide as basic data for the creation of urban forest spaces in the future.

This study investigates the effects of appearance-relative behaviors of adolescent female consumers on their awareness of heath harmfulness and skinny jeans purchasing behaviors and identifies the influential variables on the wearing satisfaction of skinny jeans. A survey was carried out with middle and high school female students and 386 responses were analyzed using descriptive analysis, factor analysis, a reliability test, and regression analysis. The results of this study were as follows, 1) From the results of the factor analysis on appearance-related behaviors and clothing benefits of skinny jeans for female adolescents, each of the variance assessments clearly showed factorial structures. 2) As a result of looking at the influences of appearance-relative behaviors on the clothing benefits of skinny jeans, respondents who paid more attention to their appearance tended to consider hygiene and activity comfort less important. In addition, respondents who had higher fashion concerns tended to consider aesthetic, practicability, desired trend, and activity comfort more important. 3) Respondents who had higher fashion concerns and considered activity comfort more important among skinny jeans benefits showed a higher level of satisfaction when wearing skinny jeans. However, respondents who thought aesthetic and health hygiene more important when buying skinny jeans showed a lower level of satisfaction when wearing skinny jeans. Female adolescents showed less satisfaction when wearing skinny jeans, as they perceived harmfulness about skinny jeans more.

Objectives: This study investigated the role of information and communication technology and women's empowerment in contraceptive discontinuation in Indonesia. Methods: The study used data from the 2017 Indonesia Demographic and Health Survey and monthly contraceptive calendar data. A Gompertz proportional hazards model was used for analysis. Results: The 12-month contraceptive discontinuation rate was higher among women who had used the Internet in the past year, women who were mobile phone owners, and women who reported having fully participated in household decision-making than among their counterparts. These factors significantly impacted the risk of contraceptive discontinuation in Indonesia, even after controlling for contraceptive method, age, parity, contraceptive intent, education, work status, place of residence, and wealth status. Conclusions: After adjustment for the control variables, a higher risk of contraceptive discontinuation was associated with having used the Internet in the past year, owning a mobile phone, and not participating in household decision-making. Higher contraceptive discontinuation risk was also associated with using contraceptive pills, older age, lower parity, intent of spacing births, more education, current unemployment, and rural residence, and the risk was also significantly higher for those in the lowest household wealth quintile than for those in the fourth household wealth quintile. The association of contraceptive discontinuation with the use of modern information and communication technology and relatively disempowerment in household decision-making may imply that information regarding family planning and contraception should be conveyed via social media as part of setting up an eHealth system. This must include a strong communication strategy to empower and educate women in contraceptive decision-making.

The aim of this study is to research and analyse how junior-high students, both male and female in Inchon area, are recognizing the contents of the curriculum in the subject of home economics and how effectively they are learning and applying it in their actual life. 772 students, both male and female, who started to learn the subject of home economics from the 7th grade as compulsory are the respondents, and the survey is done by using questionnaire. The result shows that after taking the course of home economics, both male and female students have got more positive view on the necessity of learning the subject. But still, on the whole, female students are more intersted and more active than males the subject in learning. As for food and nutrition part, large percentage of the respondents, both male and female, answer that it is very helpful. They tend to be on more balanced diet and when they purchase food or when they eat at restaurant they refer what they learn about nutrition at school more often than not. A number of the students are re-practicing cooking at home after they learn it at school. Also the fact in the survey shows that more and more mothers are getting active in asking their children to re-practice cooking. One of the difficulties for male students to take the course is stereo-typed thinking on the separate role of man and woman in the family. But many of them started cooking some food, even though it is very simple, and the survey shows that their interest in nutrition and health increased after they were initiated into this course.

This paper aims to explore the role of the home economics subject in helping high school students preparing for an independent aged life and to develop problem based teaching plans toward this goal. Contents related to the elderly in the high school home economics and technology 2007 and 2009 revised curricula were analyzed, and elderly-related contents in other subject areas (the 2009 revised curricula of ethics, public health, and social studies) were also comparatively analyzed to determine the identity of the home economics subject in relation to preparation for independent aging. Based on these analysis, five subjects and teaching plans were presented: the aging society and population changes, the characteristics of the elderly, individual preparation for aging, care of the elderly, and welfare services for the elderly. The ultimate objectives of the lessons were, through critical reasoning, to inquire into the causes of current problems the elderly face so that teenagers can understand aging societies and the elderly and to seek reasonable alternatives for teenagers as they prepare for successful and independent aging, increasing their problem-solving abilities in choosing the best course of action by considering the ripple effect of consequences of each of those alternatives. Suggestions on what direction elderly-related education should take in the future, and what roles teachers should take are also provided.
