VR(Virtual Reality), which has drawn attention as a major area in ICT, is currently being used in various fields, including medical care, movies and architecture. Although VR technology is used in various fields, contents are mainly developed by creators where needs of users are easily left out of consideration leading to failure in forming a consensus between UI(User Interface) and UX(user experience). To identify the consumer preference and attribute level of VR game content, which is responsible for the largest proportion of VR contents, this study was designed to examine the consumers' preference properties of VR game contents through a Conjoint Analysis and derive the relative importance and weightings of each group. The study collected 166 questionnaires over a total of three months from May to July 2019, 150 of which were completed (90.4%). Statistic analysis was conducted using SPSS Ver. 25.0. The results of the study showed that the genre of the game (42.6%), number of players (24.0%), price for payment (20.3%) and game planning (13.1%) were important attributes in choosing VR games. The optimal mix of attributes was derived with new games, RPGs, multi-play and medium price (22,000 KRW). Before mentioning technology in the expectations of users who use VR game content, which is the most preferred among VR contents, this study recognized the need to have a fun and new experience through VR game content. Therefore, it is expected that this will serve as a reference for consumer behavior of VR game contents and research on VR game contents development.

Oral, cervical and breast cancers, which are either preventable and/or amenable to early detection and treatment, are the leading causes of cancer-related morbidity and mortality in India. In this paper, we describe implementation science research priorities to catalyze the prevention and control of these cancers in India. Research priorities were organized using a framework based on the implementation science literature and the World Health Organization's definition of health systems. They addressed both community-level as well as health systems-level issues. Community-level or "pull" priorities included the need to identify effective strategies to raise public awareness and understanding of cancer prevention, monitor knowledge levels, and address fear and stigma. Health systems-level or "push" and "infrastructure" priorities included dissemination of evidence-based practices, testing of point-of-care technologies for screening and diagnosis, identification of appropriate service delivery and financing models, and assessment of strategies to enhance the health workforce. Given the extent of available evidence, it is critical that cancer prevention and treatment efforts in India are accelerated. Implementation science research can generate critical insights and evidence to inform this acceleration.

Projection of cancer incidence is essential for planning cancer control actions, health care and allocation of resources. Here we project the cancer burden at the National and State level to understand the magnitude of cancer problem for the various calendar years from 2011 to 2026 at 5-yearly intervals. The age, sex and site-wise cancer incidence data along with populations covered by the registries were obtained from the report of National Cancer Registry Programme published by Indian Council of Medical Research for the period 2001-2004. Pooled age sex specific cancer incidence rates were obtained by taking weighted averages of these seventeen registries with respective registry populations as weights. The pooled incidence rates were assumed to represent the country's incidence rates. Populations of the country according to age and sex exposed to the risk of development of cancer in different calendar years were obtained from the report of Registrar General of India providing population projections for the country for the years from 2001 to 2026. Population forecasts were combined with the pooled incidence rates to estimate the projected number of cancer cases by age, sex and site of cancer at various 5-yearly periods Viz. 2011, 2016, 2021 and 2026. The projections were carried out for the various leading sites as well as for 'all sites' of cancer. In India, in 2011, nearly 1,193,000 new cancer cases were estimated; a higher load among females (603,500) than males (589,800) was noted. It is estimated that the total number of new cases in males will increased from 0.589 million in 2011 to 0.934 million by the year 2026. In females the new cases of cancer increased from 0.603 to 0.935 million. Three top most occurring cancers namely those of tobacco related cancers in both sexes, breast and cervical cancers in women account for over 50 to 60 percent of all cancers. When adjustments for increasing tobacco habits and increasing trends in many cancers are made, the estimates may further increase. The leading sites of cancers in males are lung, oesophagus, larynx, mouth, tongue and in females breast and cervix uteri. The main factors contributing to high burden of cancer over the years are increase in the population size as well as increase in proportion of elderly population, urbanization, and globalization. The cancer incidence results show an urgent need for strengthening and augmenting the existing diagnostic/treatment facilities, which are inadequate even to tackle the present load.

Dental bacteria can cause gum diseases, i.e. gingivitis and periodontitis, by inducing inflammation in human gingiva. Therefore, the most effective way to prevent and treat gum diseases is the control of the inflammatory reactions induced by dental bacteria. Almost all present dental care products contain anti-bacterial agents to eliminate dental bacteria. However, recent studies report that even heat-killed dental bacteria can induce the inflammation responses in oral cells. Therefore, the method using anti-bacterial agents should be improved for better anti-inflammatory effect and the effective natural anti-inflammatory substances need to be found. In addition, the mechanisms of gingival inflammation should be elucidated. In this study, we tried to find out the mechanism of the gingival inflammation and effective natural anti-inflammatory substances with human gingival epithelial cells and Prevotella intermedia which is well known as a typical dental bacteria inducing gingivitis and periodontitis. In results, Prevotell intermedia initiated the gingival inflammation response by stimulating gingival epithelial cells to release an inflammatory cytokine, IL-8. Furthermore, the inflammation by Prevotella intermedia is related to COX-2, AP-1, and TNF-${\alpha}$ pathways. Green tea extract could effectively suppress the inflammatory responses induced by Prevotella intermedia. We find out the effective natural substance for the improvement of gum diseases by studying the mechanism of the gingival inflammation induced by dental bacteria.

This study is a descriptive research study to identify Unmet Dementia Information Needs (UDIN) for caregivers of dementia patients at Dementia Relief Center and to understand the effectiveness of the program for workers. The subjects were 114 caregivers and 217 practitioners from dementia relief centers in 25 autonomous districts of S city from November 1, 2019 to January 31, 2020. The UDIN questionnaire is a 7-point Likert scale. The Crisis Management Questionnaire is a Likert 5-point scale consisting of 10 questions from 6 categories. As a result of the study, the proportion of depressed caregivers experiencing UDIN was 12.3times higher than those who did not (p<.001). The program effectiveness was 8.98times better than those who perceived the lack of risk management as good (p=.004), and social workers were 2.81times better than nurses (p=.091). It is necessary to conduct interactive operations to meet the needs of the community residents by listening to their diverse opinions rather than simply implementing a one-sided policy to raise the service of a dementia relief center to the highest level in a short period of time.

Total fertility rate (TFR) increased from the lowest 1.08 in 2005 to 1.13 in 2006, and a debate is made whether the increase is temporary or continuous as a result of various pro-natal policies. This study intends to explore policy implications revealed in recent fertility change using vital statistics. For this purpose, tempo-adjusted fertility rate by birth order, fertility rate by age of mother and birth order, age-specific fertility for married, and age-specific divorce rate for married are analyzed. The increase of TFR and births for 2006 is largely due to increase of first births at early thirties with slowdown of delayed first marriage and first child birth. The increase of female population (the third wave effect of baby boom) and first marriages of late twenties in 2006 and 2007 would lead to increase of fertility during 2007-2008. But further increase is uncertain because of the decrease trend of marital fertility and increase trend of never-married for twenties. TFRs for first and second births reduced rapidly, while TFRs for third and above births showed no changes, and second births were largely affected by tempo adjustment of fertility. Thus, constructing social environment for first and second births is more effective and necessary than encouraging third births. In addition, social responsibility of child care, child-women health issues due to delayed births, and the need for multi-cultural family support system are discussed.

Background: The voluntary diagnosis-related groups (DRG)-based payment system was introduced in 2002 and the government mandated participation in the DRG for all hospitals from July 2013. The main purpose of this study is to examine the independent effect of mandatory participation in DRG on various outcomes of patients. Methods: This study collected 1,809,948 inpatient DRG data from the Health Insurance Review and Assessment database which contains medical information for all patients for the period 2007 to 2014 and examined patient outcomes such as length of stay (LOS), total medical cost, spillover, and readmission rate according to hospital size. Results: LOS of patients decreased after DRGs (large hospitals: adjusted odds ratio [aOR], 0.87; 95% confidence interval [CI], 0.78-0.97; small hospitals: aOR, 0.91; 95% CI, 0.91-0.92). The total medical cost of patients increased after DRGs (large hospitals: aOR, 1.22; 95% CI, 1.14-1.30; small hospitals: aOR, 1.22; 95% CI, 1.21-1.23). The results reveals that spillover of patients increased after DRGs (large hospitals: aOR, 1.27; 95% CI, 0.70-2.33; small hospitals: aOR, 1.18; 95% CI, 1.16-1.20). Finally, we found that readmission rates of patients decreased significantly after DRGs (large hospitals: aOR, 0.28; 95% CI, 0.26-0.29; small hospitals: aOR, 0.59; 95% CI, 0.56-0.63). Conclusion: The DRG payment system compared to fee-for-service payment in South Korea may be an alternative medical price policy which can reduce the LOS. However, government need to monitor inappropriate changes such as spillover increase. Since this study also is the results based on relatively simple surgery, insurer needs to compare or review bundled payment like new DRG for expansion of various inpatient-related diseases including internal medicine.

It is important to understand the potential human health implications of exposure to environmental chemicals that may act as hormonally active agents. It is necessary to have an understanding of how pharmaceutical and personal care products and other chemicals affect the ecosystem of our planet as well as human health. Endocrine disruption is defined as the ability of a chemical contaminating the workplace or the environment to interfere with homeostasis, development, reproduction, and/or behavior in a living organism or it's offspring. Certain classes of environmentally persistent chemicals such as polychlorinated biphenyls (PCBs), dioxins, furans, and some pesticides can adversely effect the endocrine systems of aquatic life and terrestrial wildlife. Research continues to support the theory of endocrine disruption. However, endocrine disruption researches have been applied to proteomics poorly. Proteomics can be defined as the systematic analysis of proteins for their identity, quantity and function. It could increase the predictability of early drug development and identify non-invasive biomarkers of tonicity or efficacy. Proteome analysis is most commonly accomplished by the combination of two-dimensional gel electrophoresis (2D/E) and MALDI-TOF mass spectrometry (MS) sr protein chip array and SELDI-TOF MS. Proteomics have an opportunity to play an important role in resolving the question of what role endocrine disruptors play in initiating human disease. Proteomics can also play an imfortant role in the evaluation of the risk assessment and use of risk management and risk communication tools required to address public health concerns related to notions of endocrine disruptors. Understanding the need for the proteomics and possessing knowledge of the developing biomakers used to abbess endocrine activity potential will he essential components relevant to the topic of endocrine disruptors.
