Korean society with low fertility rate and high aging rate crisis has been tried very hard to find out alternatives to solve these social problems. These efforts resulted in increasing the development of education programs for the elderly. The education for the elderly have been development in various different academic fields. Therefore, this is the time to establish database for education programs which developed so far. The purpose of this study is to examine research trend in the field of education programs for the elderly in Korea. For this purpose, 62 education programs for the elderly which developed so far were analyzed. The results of this study were as followed. The topics of education programs for the elderly were divided into the following : a marriage enrichment programs for the elderly married couples, leisure programs, death education programs, health education programs, economic education programs, education programs for grandparents raising their grandchildren, etc. Based on the results of this analysis, the tasks of future research about education programs for the elderly were presented.

Background: Health statistics of pharmaceutical use and expenditure are essential to make and implement evidence-based pharmaceutical policy. This study aims to demonstrate the methods and results of pharmaceutical consumption and sales in 2018 according to the sources and methods given by the Organization for Economic Cooperation and Development (OECD). Methods: The medication list contains 39,346 medicines both reimbursed and non-reimbursed by the National Health Insurance in 2018. We used the therapeutic categories based on Anatomic Therapeutic Chemical Classification of World Health Organization. This study analyzed National Health Insurance claims data and supply data generated from wholesalers to health care facilities. The indicators are defined daily dose (DDD), per 1,000 inhabitants per day and US$ per capita. Results: In South Korea, the number of medications to which DDD were assigned was 18,055 and it was 45.9% of the total number of medications on the list. The consumption in anti-infective for systemic use (J) and musculo-skeletal system (M) was higher than the mean consumption among the OECD countries. The pharmaceutical sales per person in Korea was also higher than the mean sales per person across the OECD countries. Conclusion: We sought to explain the methods to produce pharmaceutical consumption and sales statistics which we had submitted annually to OECD. Considering the characteristics of pharmaceutical statistics, a direct comparison should be approached with caution. Since the growth in pharmaceutical spending has greatly increased over the past decade, we need to monitor pharmaceutical consumption and expenditure consistently.

This study aims to propose the implementation of innovative payment models in Korea in order to promote the financial sustainability of the national health insurance system by reviewing the current status of the payment system in Korea and examining other countries' experiences with various innovative payment models. Korea primarily uses a fee-for-service payment system and additionally uses various payment systems such as case payment, per diem, and pay-for-performance. However, each payment system has its limitations. Many OECD (Organization for Economic Cooperation and Development) countries have pointed out the limitations of existing payment systems and have been attempting various innovative payment models (e.g., add-on payment, bundled payment, and population-based payment). Therefore, it is essential for Korea to consider innovative payment models, such as a mixed payment model that takes into account the strengths and weaknesses of each payment system, and to design and pilot these models. This process requires stakeholders to work together to build a social consensus on the implementation of innovative payment systems and to refine legal and systematic aspects, develop an integrated health information system, and establish dedicated organizations and committees. These efforts towards innovative payment models will contribute to developing a sustainable health insurance system that ensures the public's health and well-being in Korea.

Toxicity of ocean dumping wastes(dye waste, urban sewage, food waste) were examined by observing fertilization and embryo development rates of the Sea Urchin, Strongylocentrotus nudus. Spawning was induced by injecting 1 mL of 0.5 M KCl into coelomic cavity. Males released white or cream-colored sperms and females released yellow or orange-colored eggs. Experiments were began within 30 min after the collection of both gametes. The fertilization and embryo development rates tests were performed for 10 min and 48 h after fertilization, respectively. The fertilization and embryo development rates in the control condition(not including ocean dumping wastes sludge elutriate) were greater than 90%, but markedly decreased with increasing concentrations of ocean dumping waste sludge elutriate. The fertilization and normal embryogenesis rates were significantly inhibited in all waste sludge elutriate from dye waste($EC_{50}$=5.76; $EC_{50}$=4.53), urban sewage($EC_{50}$=9.82; $EC_{50}$=9.67) and food waste($EC_{50}$=3.90; $EC_{50}$=3.27), respectively. The NOEC(>3.13%) and LOEC(3.13%) of fertiliztion and normal embryogenesis rates very similar in all waste sludge elutriate. These results suggest biological assay using the fertilization and embryo development rates of S. nudus are very useful test method for the ecological toxicity assessment of ocean dumping wastes.

Bacteroides sp. CACC 737 was isolated from a feline, and its potential probiotic properties were characterized using functional genome analysis. Whole-genome sequencing was performed using the PacBio RSII and Illumina HiSeq platforms. The complete genome of strain CACC 737 contained 4.6 Mb, with a guanine (G) + cytosine (C) content of 45.8%, six cryptic plasmids, and extracellular polysaccharide gene as unique features. The strain was beneficial to animal health when consumed as feed, for example, for ameliorating immunological dysfunctions and metabolic disorders. The genome information adds to the comprehensive understanding of Bacteroides sp. and suggests potential animal-related industrial applications for this strain.

Human exposure to nano-sized particles (NSP) has increased over the last century with anthropogenic sources, and the rapid development of nanotechnology becomes an another source of such exposure. Information regarding the safety of nanotechnology and its product, nanoparticles, is urgently needed when assuming exposure through inhalation, oral intake, and penetration across skin is ever increasing as growing nanotechnology rapidly. The recent advancement of biokinetic studies with NSP and newer epidemiologic and toxicologic studies with ultrafine particles can be the basis for the nanotoxicology. Some concepts of nanotoxicology can be known from the results of these results. Specific small size of NSP, when inhaled, facilitates deposition by difusional mechanism in all regions of the respiratory tract and uptake into cells, ranscytosis across epithelial and endothelial cells into the blood and lymph circulation to reach target sites. Translocation along axons and dendrites of neuron makes an access to CNS and ganglia. These biokinetics are dependent on NSP surface chemistry. Risk assessments of NSP include appropriate and relevant doses/concentration selections, the increase effects in the organism and the benefits of possible desirable effects. An interdisciplinary team approach is desirable for nanotoxicology research and an appropriate risk assessment.

The microalgae, Microcystis aeruginosa are able to proliferate in a wide range of freshwater ecosystem. M. aeruginosa was cultivated in 25 L and 240 L race-way reactor containing modified medium with added urea 0.2 g/L, increased $Fe^{+2}$, and decreased $Ca^{+2}$ion compared to BG11 medium. Sugar contents of M. aeruginosa grown in BG11 medium, and modified medium were 120 mg/mL and 140 mg/mL respectively. Fermentation was conducted with the extract of M. aeruginosa at $30^{\circ}C$ for 30 h, using Saccharomyces cerevisiae (Sc), Pichia stipitis (Ps), Zymomonas mobilis (Zm), and mixed-culture of these strains (Sc + Ps + Zm). Pichia stipitis (0.7%) was found to be more suitable for producing bioalcohol from M. aeruginosa extract than other strains of Saccharomyces cerevisiae (0.45%) and Zymomonas mobilis (0.61%), while mixed-cultured of these strains showed higest productivity by 1.75%. Biomass of M. aeruginosa contains the potency to be the most renewable resource for bioalcohol fermentation.

As people have paid much attention to their health along with increased interest in high quality of living, they have managed their health in organized manners. Space is a physical field which directly and indirectly interacts with human life, there is a little research on its therapeutic aspect and it is only negatively applied for development of products and alternative medicine. This study aims to identify research trends and flows targeting previous research on therapeutic approaches in domestic space design and present basic materials on space design approaches in a therapeutic view, which will be helpful in ultimate development of space design in theories and practices. As a result, it was discovered that there were only a few papers which were searched with direct key words on curative environment, which indicates that specific studies as therapeutic approaches are insufficient. When the studies were analysed according to annual publications, research on residential welfare and medical space was active, and research on design methodology, design techniques, and design plans was active, but research on psychology, behaviors, laws and institutions was relatively insufficient, which indicates studies on physical and psychological aspects of space design are necessary. In conclusion, it is suggested that further studies on therapeutic environment for direct and specific persons should be defined and classified although there have been relevant studies in various fields.

The present study aimed to examine the mediation effect of identity development between perceived parental academic achievement pressure (PPAAP) and mental health. Specifically, we examined whether the relation between PPAAP and mental health is mediated by the positive or negative aspects of identity development. Participants were 110 Korean college students. They completed online self-report questionnaires that included PPAAP, identity development, personal well-being, and depression. We found that PPAAP was negatively related to personal well-being and positively related to depression. Moreover, the relation between PPAAP and mental health was mediated only by the negative aspects of identity development. In other words, PPAAP was related to the negative aspects of identity development, which, in turn, was negatively associated with mental health. This study contributes to the literature in that it proposed identity development as a mediator between PPAAP and mental health and found that the negative, not positive, aspects of identity development mediated the relation. We suggest that institutional interventions that help develop identity can be an effective way to mitigate the negative impacts of PPAAP on mental health of children living in the highly competitive Korean society. Limitations and future research directions are also discussed.

Background: Health, safety, and well-being (HSW) at work represent important values in themselves. It seems, however, that other values can contribute to HSW. This is to some extent reflected in the scientific literature in the attention paid to values like trust or justice. However, an overview of what values are important for HSW was not available. Our central research question was: what organizational values are supportive of health, safety, and well-being at work? Methods: The literature was explored via the snowball approach to identify values and value-laden factors that support HSW. Twenty-nine factors were identified as relevant, including synonyms. In the next step, these were clustered around seven core values. Finally, these core values were structured into three main clusters. Results: The first value cluster is characterized by a positive attitude toward people and their "being"; it comprises the core values of interconnectedness, participation, and trust. The second value cluster is relevant for the organizational and individual "doing", for actions planned or undertaken, and comprises justice and responsibility. The third value cluster is relevant for "becoming" and is characterized by the alignment of personal and organizational development; it comprises the values of growth and resilience. Conclusion: The three clusters of core values identified can be regarded as "basic value assumptions" that underlie both organizational culture and prevention culture. The core values identified form a natural and perhaps necessary aspect of a prevention culture, complementary to the focus on rational and informed behavior when dealing with HSW risks.
