In support of current and upcoming large-volume cosmological surveys such as the SDSS-IV eBOSS, LSST, and DESI, we present an extensive suite of high-resolution cosmological hydrodynamical simulations spanning a large range of cosmological and astrophysical parameters. We follow the evolution of gas, dark matter, neutrinos, and dark radiation, and consider several combinations of box sizes and number of particles - enhancing the resolution up to $3{\times}33283=110$ billion particles in a (100 h-1 Mpc)3 box size. We also provide 100,000 skewers for a variety of redshift slices and combination of cosmological and astrophysical parameters, useful for interpreting upcoming high-quality $Lyman-{\alpha}$ forest data. These novel simulations represent an improvement over our previous runs, and can be useful for a broader variety of cosmological and astrophysical applications, ranging from the three-dimensional modeling of the $Lyman-{\alpha}$ forest to cross-correlations between different probes, for studying the expansion history of the Universe including massive neutrinos, and for particle-physics related topics.

With research data generation on the rise, Institutional Repositories (IR) are one of the tools to manage it. However, the variety of data practices across institutions, domains, communities, etc., often requires dedicated studies in order to identify the research data management (RDM) require- ments and mapping them to IR features to support them. In this study, we investigated the data practices for a few national universities in North Macedonia, including 110 participants from different departments. The methodology we adopted to this end enabled us to derive some of the key RDM requirements for a variety of data-related activities. Finally, we mapped these requirements to 6 features that our participants asked for in an IR solution: (1) create (meta)data and documentation, (2) distribute, share, and promote data, (3) provide access control, (4) store, (5) backup, and (6) archive. This list of IR features could prove useful for any university that has not yet established an IR solution.

Ranging from a variety that a consumer to purchase and consume, and a variety with high quality and pest resistance, sustaining biological diversity as well as hiring global experts who understand breeding policy, it tightly maintains relationship with producer, consumer, and exporter to promote superior species for customized export to exporting country. By carrying out researches on cost saving and how to shorten the period of apple to cultivate, it consolidates its stance as a competent apple exporting country of apple and pear with high competetiveness. In order to compete against apple and pear of New Zealand, farmers argue that they need budget and researchers also argue that "No money, no research." Due to certain limit of governmental budget support, it is believed that it is time to fund our own way to promote apple research center. To come up with the best apple production, all of those who associates with apple such as farmers, researchers, government, exporters, and consumer should do their best to enhance the apple and pear industry.

Research related to Web-based learning (WBL) has grown exponentially in the last decade. Scholars have explored a variety of areas related to WBL, including techniques, strategies and best practices. One area of particular interest to scholars is the potential of WBL to support and facilitative collaborative learning. Despite the continued exploration, there continues to be a concern related to the theoretical foundations of WBL. The purpose of this article is to explore how different theories may be used to guide research and inform practice in online collaborative learning. We integrate the major points drawn from current research and theory from a variety of perspectives so as to gain a better understanding of how learning is enabled by asynchronous modes of online collaborative learning. We then use this understanding to identify opportunities and challenges for theory development and research in WBL.

The purpose of this study was to investigate the diet of children under the government-funded meal support program. The 143 children (67 boys and 76 girls) participated in this study among $4^{th}-6^{th}$ elementary school students receiving free lunches during the summer vacation of 2007 and living in Gwanak-gu, Seoul, Korea. The subjects consisted of four groups supported by Meal Box Delivery (n = 26), Institutional Foodservice (n = 53), Restaurant Foodservice (n = 27), or Food Delivery (n = 37). A three-day 24-hour dietary recall and a self-administered survey were conducted. In addition, the children's heights and weights were measured. The average energy intake of the children was 1,400 kcal per day, much lower than the Estimated Energy Requirements of the pertinent age groups. The results also showed inadequate intake of all examined nutrients; of particular concern was the extremely low intake of calcium. On average, the children consumed eight dishes and 25 food items per day. The children supported by Meal Box Delivery consumed more various dishes and food items than the other groups. The percentage of children preferring their current meal support method was the highest in those supported by Meal Box Delivery and the lowest in those supported by Food Delivery. We requested 15 children among the 143 children participating in the survey to draw the scene of their lunch time. The drawings of the children supported by Institutional Foodservice showed more positive scenes than the other groups, especially in terms of human aspects. In conclusion, the overall diet of children under the government-funded meal support program was nutritionally inadequate, although the magnitude of the problems tended to differ by the meal support method. The results could be utilized as basic data for policy and programs regarding the government-funded meal support program for children from low-income families.

Purpose: This study examined the relationship between acculturation stress and health promotion behaviors in the Korean Chinese elderly immigrants living in Korea, focusing on the buffering effects of social support. Methods: We included 132 completed questionnaires in the analysis. The buffering effect was examined using a hierarchical regression analysis by adding interaction terms. Results: Health promotion scores were significantly higher in the group with a higher education level, lower depressive symptom scores, and higher levels of social support. However, no statistically significant differences were found in the health promotion behaviors by gender, age, spouse, job, financial stability, subjective health status, chronic disease, regular health checkups, or acculturation stress. The hierarchical regression analysis demonstrated that social support had a buffering effect on the relationship between acculturation stress and health promotion behaviors in the Korean Chinese elderly immigrants. Specifically, the relationship between the acculturation stress stemming from the difficulties in the workplace and health promotion behaviors was attenuated by social support. Conclusion: These findings indicate that social support significantly moderates the relationship between acculturation stress and health promotion behaviors in the Korean Chinese elderly immigrants living in Korea. A variety of strategies to enhance social support should be incorporated in the health promotion programs to decrease the negative effects of acculturation stress in the Korean Chinese elderly living in Korea.
