Purpose: Wasting and underweight are the 2 main indicators of children's undernutrition. We aimed to estimate the prevalence of undernutrition at the national level in Iran. Methods: We performed a search for original articles published in international and Iranian databases including MEDLINE, Web of Science, Google Scholar, Scopus, CINHAL (Cumulative Index to Nursing and Allied Health Literature), Scientific Information Database, Irandoc, Iranmedex, and Magiran during January 1989-August 2017. Seven keywords, in English and Persian, including malnutrition, protein energy malnutrition, growth disorders, underweight wasting, weight loss, children below 5 years old, and children, were used to search the databases. Results: Finally, 17 articles were included in the meta-analysis, based on which the prevalence of underweight and wasting in Iranian children were estimated to be 11% and 5%, respectively. The prevalence rates of underweight among children in the central, western, southern, and northern parts of Iran and at the national level were 24%, 5%, 20%, 17%, and 6%, respectively. The prevalence rates of wasting in the central, western, southern, and northern parts of Iran and at the national level were 9%, 4%, 11%, 5%, and 4%, respectively. Conclusion: Although the prevalence of underweight and wasting in Iran was low, some parts of the country showed high prevalence. The main reason behind this difference in the prevalence of malnutrition may be due to the level of development in different regions.

Purpose: The purpose of this study is to identify effects of the variables of Health Action Process Approach (HAPA) Model on physical activity. Methods: This study has conducted a systematic literature review and meta-analysis. Sixteen articles were searched through electronic databases (PsycINFO, PubMed, CINAHL, Web of science, Science Direct, RISS, KMBASE, KoreaMed, KISS, DBpia) and additional journals from 2000 to July, 2017. To estimate the effect size (ES), the meta-analysis of the studies was performed by using Comprehensive Meta-Analysis programs. Results: The overall effect size of the variables of HAPA on physical activity was median (ES=.28). Of the core variables of HAPA model, action control (ES=.43) showed the largest effect size, followed by coping self-efficacy (ES=.31) and planning (ES=.31).Additional variables were identified as preparatory behavior (ES=.39) and past physical activity (ES=.24). Through the moderator effect analysis, the effect size was higher in the volitional phase than in the motivational phase, and higher in the healthy group than in the patient group. The higher the proportion of males and the lower the age, the larger the effect size. Conclusion: This finding shows empirical evidence that all core variables of the HAPA model are useful for predicting physical activity. We propose the use of the HAPA model to develop physical activity promotion intervention.

Purpose: The purpose of this study was to analyze the mental health and health risk behaviors of multicultural adolescents according to their mothers' native country. Methods: For this study raw data from the 11th Youth Health Behavior Online Survey (2015) was examined. Mental health and health risk behaviors for 62,985 adolescents were analyzed according to their mothers' native country. Collected data were analyzed with the SPSS program using descriptive statistics and logistic regression analysis, to which the complex sample design was applied. Results: The odds ratio of depression in multicultural adolescents compared to Korean adolescents was 44.92 (CI: 5.77-349.59) for adolescents whose mothers came from Cambodia and 3.00 (CI: 1.57-5.76) for adolescents whose mothers came from North Korea. The odds ratio of attempted suicide was 14.73 (CI: 3.09-70.22) for adolescents whose mothers came from Cambodia and 8.63 (CI: 3.45-21.62) for adolescents whose mothers came from North Korea. The odds ratio of problematic drinking in multicultural adolescents was 7.47 (CI: 1.71-32.67) for adolescents whose mothers came from Mongolia. Conclusion: Findings indicate that when planning a health promotion program for adolescents from multicultural families, a customized approach should be sought taking into account the characteristics of mothers' native country.

The recognition of the natural background radiation is important not only for radiological education but also for the promotion of people's scientific view about radiation. We made a "room" on the web showing natural background radiation as part of a VRM (Virtual Radiation Museum). The "room" shows the video images of the tracks of charged particles from natural background radiation, alpha and beta ray track from known sources using a Large Scale Diffusion Cloud Chamber. The purpose of this study is to make clear the origin of a kind of track (named A-track) which is thick and easy to recognize with the length less than several cm in the cloud chamber, and to make numerical explanation of its counting rate. The study was carried out using a Large Scale Diffusion Cloud Chamber (Phywe, Germany) installed in the Niigata Science Museum. The Model RNC (Pylon Electronics, Canada) was used as Rn-222 source. Ra-226 activity in RNC was 111.6 Bq calibrated with NIST protocol. Rn-222 gas was injected into the cloud chamber. Continuous video recording with use of Digital Handycam (SONY, Japan) was carried out for 360 min. after injection of Rn-222 gas. The number of alpha-ray track (alpha track) in the video images was analyzed. The growth and decay curve of the total activity of Rn-222 and its alpha emitting progeny were calculated and compared with the count of the alpha tracks. As a result the alpha tracks formed by Rn-222 injection resemble A-Tracks. The relationship between A-track in the cloud chamber and atmospheric Rn is discussed.

To develop a public services framework for the promotion of the public records use of the regional archives in Korea, we analyzed the previous related studies and observed the public services of the renowned overseas regional archives through the we sites. Then, the web 2.0 technology and its application to archives services have been studied. Based on the analysis, a public services framework consisting of 4 phases such as basic services, extended services I, extended services II, interactive services was developed. This framework of 4 phases is not a fixed universal system. Each of the regional archives would select the services they offer according to the budget, personnel, as well as the user community. Finally, community survey, user satisfaction evaluation, and the establishment of specific service guidelines are suggested for the advancement of the public services.

Objective: The study analyzed degrees of participation in physical activities, demographic and sociological characteristics of middle and high school students, and the relations to mental health related factors, based on "Korea youth risk behavior web-based survey." Therefore, the study can be used as preliminary data for establishing mental health promotion plans for youth and setting contents and directions of health education. Methods: The study analyzed the data, collecting from 75,066 middle and high school students, regarding their demographic and sociological characteristics, mental health, and relations to physical activities by using SPSS Win 15.0. Results: 19.1% of the students answered they had seriously contemplated suicide during the past 12 months, and 43.2% said they are usually under enormous pressure. 55.3% answered that academic achievements and the pressure from future paths are major factors of their stress. The students showed noteworthy differences in whether they think about suicide depending on whether the students live with their father or mother. The study found that the students whose parents' levels of education are low, or their academic records are low, or economic conditions are poor are more likely to think about suicide. The students tend to think more about killing themselves if they spend more time sitting to study than being engaged in physical activities, or spend little time walking. And they are more likely to think about committing suicide if they spend little time exercising, or are not engaged in physical activities on the playground or a gym in PE classes.
