Iron is an essential ingredient for all metabolism in a living body However, because of the very low content of the iron in foods, many researches have been performed about iron-fortified food additives. We developed an iron-fortified food additive using the liposome that contain ferrous sulfate and hemin. For preventing the autoxidation of the ferrous sulfate, ascorbic acid was applied. Also, to prevent the oxidation of the liposome induced by the added ferrous sulfate and/or hemin, $\alpha$ -tocopherol was additionally applied. Though the effect of the added aqueous ascorbic acid did not show the antioxidative activity on the liposome containing ferrous sulfate and/or hemin, the added $\alpha$ -tocopherol in the phospholipid bilayer could retard the oxidation of the liposome. These results support that the liposome containing ferrous sulfate, hemin and ascorbic acid with the incorporated $\alpha$ -tocopherol could be applied in the food industry as an iron-fortified additive.

To provide functional properties in fish paste, Styela plicata (Korean name: omandungi) having antioxidant and anticarcinogenic activity was added at 0, 5, 10, 15, and 20%. The fried fish pastes were investigated for color, textural properties, and sensory attributes. Fish paste containing 15% S. plicata showed the lowest values in lightness (L) and the highest values in redness (a) and yellowness (b). All test samples with 3 mm thickness had good flexibility and did not break even after folding 4 times. Fish paste containing 20% S. plicata showed the highest values in strength, hardness, and adhesiveness. In overall acceptance of sensory evaluation, fish paste containing 15% S. plicata acquired the highest score. These results support that S. plicata can be applied to fish paste products for the purpose of high quality and functionality.

Purpose: The purpose of this study was to compare the health-related quality of life of premature menopausal women with that of normal postmenopausal women and to identify factors related to quality of life in these two groups. Methods: A secondary analysis was conducted of a sample of 5,910 postmenopausal women drawn from women aged 19-79 years, using raw data from the Korea National Health and Nutrition Survey between 2014 and 2017. Quality of life was compared between premature menopausal women and normal postmenopausal women using the t-test and chi-square test, and factors related to quality of life were analyzed by multivariate logistic regression using SAS version 9.4. Results: There was no significant difference in quality of life between premature menopausal women and normal postmenopausal women. Subjective health status and symptoms of depression were identified as factors related to quality of life in women with premature menopause, while engaging in aerobic physical activity, subjective health status, stress, and symptoms of depression were found to be related to quality of life among normal postmenopausal women. Conclusion: It is necessary to support self-care measures for both premature and normal menopausal women to adapt to changes caused by menopause, and multidimensional strategies should be developed considering postmenopausal women's subjective health status and symptoms of depression to improve their quality of life.

The enzyme activities of creatine kinase (CK), its isoenzyme MB (CK-MB) and of lactate dehydrogenase isoenzyme 1 (LD-1) have been used for years in diagnosing patients with chest pain in order to differentiate patients with acute myocardial infarction (AMI) from non-AMI patients. These methods are easy to perform as automated analyses, but they are not specific for cardiac muscle damage. During the early 90's the situation changed. First, creatine kinase ME mass (CK-MB mass) replaced the measurement of CK-MB activity. Subsequently cardiac-specific proteins, troponin T (cTnT) and troponin I (cTnI) appeared and displacing LD-1 analysis. However, troponin concentrations in blood increase only from four to six hours after onset of chest pain. Therefore a rapid marker such as myoglobin, fatty acid binding protein or glycogen phosphorylase BB could be used in early diagnosis of AMI. On the other hand, CK-MB isoforms alone may also be useful in rapid diagnosis of cardiac muscle damage. Myoglobin, CK-MB mass, cTnT and cTnI are nowadays widely used in diagnosing patients with acute chest pain. Myoglobin is not cardiac-specific and therefore requires supplementation with some other analyses such as troponins to support the myoglobin value. Troponins are very highly cardiac-specific. Only the sera of some patients with severe renal failure, which requires hemodialysis, have elevated cTnT and/or cTnI without there being any evidence of cardiac damage. The latest studies have shown that elevated troponin levels in sera of hemodialysis patients point to an increased risk of future cardiac events in a similar manner to the elevated troponin values in sera of patients with unstable angina pectoris. In addition, the bedside tests for cTnT and cTnI alone- or together with myoglobin and CK-ME mass can be used instead of quantitative analyses in the diagnosis of patients with chest pain. These rapid tests are easy to perform and they do not require expensive instrumentation. For the diagnosis of patient with chest pain, routinely myoglobin and CK-ME mass measurements should be performed whenever they are requested (24 h/day) and cTnT or cTnI on admission to the hospital and then 4-6 and 12 hours later and maintained less than 10% in imprecision.

The purpose of this study was to assess the impact of childbirth on socioeconomic status changes of women. Data were collected from Korean Health Panel (2008-2015). A difference-in-differences model with propensity score matching was applied to assess the impact of childbirth on socioeconomic status changes. As a result, variables showing significant differences in the interaction terms indicating the impact of birth were the savings, economic activity, and occupational status. The impact of birth were significant in decreasing the amount of savings and negatively affecting women's economic activities, but in increasing the probability of full-time and regular employees in occupational status. Childbirth appears to have a negative impact on the home economics and socioeconomic status of women. The belief that home economies can be stabilized even after childbirth should be established, and a long-term and sustained support plan should be set up to realize this belief.

Objectives: In Indonesia, 61 million adults smoked in 2018, and 59 million were exposed to secondhand smoke at offices or restaurants in 2011. The Presidential Decree 109/2012 encouraged local governments to implement a smoke-free policy (SFP), and the city of Jayapura enacted a local bill (1/2015) to that effect in 2015. This study aimed to evaluate compliance with this bill and to explore challenges in implementing it. Methods: We conducted a mixed-methods study. Quantitatively, we assessed compliance of facilities with 6 criteria (per the bill): the presence of signage, the lack of smoking activity, the lack of sale of tobacco, the lack of tobacco advertisements, the lack of cigarette smoke, and the lack of ashtrays. We surveyed 192 facilities, including health facilities, educational facilities, places of worship, government offices, and indoor and outdoor public facilities. Qualitatively, we explored challenges in implementation by interviewing 19 informants (government officers, students, and community members). Results: The rate of compliance with all 6 criteria was 17% overall, ranging from 0% at outdoor public facilities to 50% at health facilities. Spatial patterning was absent, as shown by similar compliance rates for SFP facilities within a 1-km boundary around the provincial and city health offices compared to those outside the boundary. Implementation challenges included (1) a limited budget for enforcement, (2) a lack of support from local non-governmental organizations and universities, (3) a lack of public awareness at the facilities themselves, and (4) a lack of examples set by local leaders. Conclusions: Overall compliance was low in Jayapura due to many challenges. This information provides lessons regarding tobacco control policy in underdeveloped areas far from the central government.

Kon - Ha Thanh River basin is the largest and the most important river basin in Binh Dinh, a province in the South Central Coast of Vietnam. In the lower rivers, frequent flooding and inundation caused by heavy rains, upstream flood and or uncontrolled flood released from upstream reservoirs, are very serious, causing damage to agriculture, socio-economic activity, human livelihood, property and lives. The damage is expected to increase in the future as a result of climate change. An advanced flood warning system could provide achievable non-structural measures for reducing such damages. In this study, we applied a modelling system which intergrates a 1-D river flow model and a 2-D surface flow model for simulating hydrodynamic flows in the river system and floodplain inundation. In the model, exchange of flows between the river and surface floodplain is calculated through established links, which determine the overflow from river nodes to surface grids or vice versa. These occur due to overtopping or failure of the levee when water height surpasses levee height. A GIS based comprehensive raster database of different spatial data layers was prepared and used in the model that incorporated detailed information about urban terrain features like embankments, roads, bridges, culverts, etc. in the simulation. The model calibration and validation were made using observed data in some gauging stations and flood extents in the floodplain. This research serves as an example how advanced modelling combined with GIS data can be used to support the development of efficient strategies for flood emergency and evacuation but also for designing flood mitigation measures.

This study tried to develop Jinmal dasik using pine nuts leaf powder with antibacterial and antioxidant properties. After preparing the Jinmal dasik in proportions of 0%, 2%, 4%, 6%, and 8% by varying the ratio of pine needle powder, the moisture, color, physical properties, antioxidant properties and sensory quality were measured. Except for the 8% Jinmal dasik, the L value of chromaticity significantly decreased as the amount of pine needle powder increased (p<0.001). In addition, the value significantly decreased with increased density (p<0.001). Based on our physical properties evaluation results, the hardness, cohesiveness, and elasticity decreased significantly as the amount of pine needle powder increased (p<0.001), but adhesion and chewiness increased significantly with an increase in the amount of pine needle powder (p<0.001). Total polyphenol content was significantly increased except for the 8% Jinmal dasik (p<0.001). DPPH and ABTS also increased significantly as the amount of pine needle powder increased (p<0.001). Our sensory evaluation, showed the 2% Jinmal dasik to have the highest degree of preference, however, there was no significant difference among the proportion groups (p=0.053).

This study aims to apprehend resources that affect level of happiness according to the types of work and leisure in single-person households, and suggests measures to effectively manage. Single-person households not only have different demographic characteristics such as gender and age, but also they have different resources, so there is a need to look at them simple as an individual subject, but as a complicated system from more integrated view. Thus, this study saw the single-person household as an organism existing in a complicated environment based on examining the previous researches. This work deigned the research model by applying the human ecological point of view consistently interacting with the environment. This study suggested an hypothesis under the assumption that the resources such as leisure, infrastructure, social activity and work-life balance support system will influence the level of happiness of single-person household

The purpose of this study was to suggest qualitative improvement through various student-centered curriculum's teaching experiences focusing on physical education. For this, class diaries, memos, lesson plans, student reviews, and videos for the past four years (2017-2020) were collected and analyzed from four high schools in kyonggi-do, and six students were interviewed. The common features between each student-centered curriculum were to have many students with the purpose of entrance examination and with concern about time conflicts between class and their dinner. In contrast, the differences between each student-centered curriculum were the required level of writing lesson plan, the level of interest and role of a class supervisor, and educational expected effect of students under a given condition. In summary, pre-education experience should be required and class activity support and various evaluation methods should be also needed.
