As the COVID-19 crisis continues, working environments and lifestyles have been changed unexpectedly, therefore the importance of mental health in the working environments has been highlighted. When the workers' mental health deteriorates, there will be personal losses but also human resources losses caused productivity decrements of the company or the organization. Many researchers have been tried to solve these issues with the help of ICT technologies such as wearable devices. Most wearable healthcare devices have been designed to detect the physiological status of users and collect the physical activities of users, and their applications are gradually expanding. Those devices may be good candidates to prevent loss of human resources from working environments especially under the COVID-19 situation by continuously monitoring mental health status in connection with mobile devices and managing the mental health on their own by combining mental well-being with support solutions. In this paper, the development trend of mental health measurement and mental well-being support technologies is analyzed, and development prospects are examined.

The study aimed to identify major factors related to global self-rated health of the community-dwelling elderly people in rural areas. Interviews were conducted with 433 persons over 65 years of age. The socio-economic characteristics, chronic disease status, measures of functional and mental health, life satisfaction, health-related behaviors including smoking, drinking, exercise, social activity, dietary habit, and food intakes were analyzed to determine their influence on self-rated health index. Data on food intake were obtained through the 24-hour recall method. The self-rated health of rural elderly was poor or very poor as reported by 42.6% and 52.4% of the men and women, respectively. Poor self-rated health was found to be related to elderly aged $65{\sim}74$, female, absence of work, more chronic diseases, dependence on Instrumental Activity Daily Living (IADL), higher mental unhealthy days, lower current life satisfaction, less social activity, lower dietary habit scores, lower intake of total food, fruit, eggs, fishes & shell fishes, vitamin C (%RDA), and Nutrient Adequacy Ratio (NAR). The results of the multiple regression analysis showed that poor self-rated health index is significantly associated with more chronic diseases, mental unhealthy days, gastrointestinal disease, musculoskeletal disease, less social activity, and lower intake of fruits. The results also suggested that improving the nutritional status and functional ability, and reducing the burden of chronic diseases are beneficial to the self-rated health index of the elderly.

This study purpose to identifying the roles of Health Information Librarian which its role is increasing according to increase recent interest in wellness and health. In other words, this study will present the Education, careen duties and so on, which should be possed by Health Information Librarian, based on the analysis of Job Site. As as result, first, health information professional librarian's name appears very diverse, and consumer health information librarian will be appropriate name for public libraries and medical librarian will be appropriate for medical library and hospital library. Second, education experience required for health information librarian is master's degree of library and information science and bachelor's or more health related degree. Third, at least two years of health-related field experience, particularly health information service experience, is required. Forth, excellent communication skills and interpersonal skills are required, expecially higher knowledge for health-related information resources is required. Fifth, the main duties what health information librarian need to perform, are library management services, training services, research services, access to and sharing of information resources, collection management, information management, information management technology, and advocacy.

The diterpene acid 1 was isolated from the roots of Anisotome lyallii(Apiaceae/Umbelliferae). The structure of the compound was elucidated as anisotomenoic acid 1 on the basis of spectroscopic method. This compound was evaluated against p388 murine leukaemia and B16/F10 melanoma cells.

This study aimed to discover functional materials derived from resources, which can improve the troublesome symptoms of a bronchus by improving bronchial hyperresponsiveness as air pollution in Korea caused by fine dust and yellow dust is getting worse. Of natural resources grown naturally in Korea, Chrysanthemum morifolium(CM), and Scutellaria baicalensis(SB) have been used as a safe raw material for drinking or medicine for a long time, and it has been found that a combination of CS73 can improve bronchial health function in experimental animal models. Analysis of serum of animal models with asthma induced by ovalbumin (chicken egg albumin) and analysis of cytokine production in BALF (Bronchoalveolar lavage fluid) showed that inflammatory indices IL-1β, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17A, IL-17F, and IL-17E were significantly reduced and that respective production of IL-2 and IFN-γ was significantly increased in the group taking extracts from CS73 when compared with the control group. These results suggested that the combination of CS73 could be used as a natural treatment for asthma. In addition, in the animal models that the combination of CS73 significantly decreased the respective production of IgE, histamine and TSLP when compared with the control group. In experimental models, the ratio of Chrysanthemum morifolium to Scutellaria baicalensis of 7 : 3 had more excellent effect than other combined experimental groups, which suggests that the above combination can be developed as a natural treatment for asthma and is valuable as a pharmaceutical composition with an effect of improving bronchial health, capable of contributing to the public health threatened by fine dust.

The study intends to conduct an analysis of relations between efficiency of investment to human resources and the operating margin in hospitals. The analyzed results are as follows: First, it is found out that an index related to labor productivity(the monthly value added per bed, the value added ratio to gross revenue), and an index for efficiency of human resources(value added to personnel expenses), do not have a significant difference by years. Second, labor productivity, indicating the efficiency of human resources, does not have a significant difference between regions and between hospital types. But there is a significant difference according to types of establishment: private hospitals have higher labor productivity(efficiency of human resources) than corporate hospitals. The hospital size is small have significantly higher labor productivity. As a result of a follow-up check, it is found out that there is separation between a group with more than 200 beds and a group with less than 200 beds. Third, at the relations between the indices related to value-added productivity and the operating margin that the higher the value added ratio to gross revenue and the higher labor productivity, the higher the operating margin. Especially, labor productivity(value added to personnel expenses), an index for the efficiency of human resources, out of all the indices related value added productivity, has the most significant influence on the operating margin.

It has been known that health industry clusters promote economy of a nation in a macro view and make growth and development of individual firm. As a result, Korean health industry has been grown to play a role of making a high value added in Kwangkyo, Daedeok, Wonju, and Songdo. Using 156 firms locating in health industry clusters such as Kwangkyo, Daedeok, Wonju, and Songdo in increasing value added, this study investigated the structural relationships among R&D resources, R&D collaboration, policy support, and operational performance. All hypotheses, except a hypothesis for the effect R&D resources on operational performance, are reported to be statistically significant. In other words, the positive effect of R&D resources on policy support is reported. And policy support and R&D collaboration positively affect operational performance, and also the positive effect of policy support on R&D collaboration is reported. From the empirical results, we can know that policy support and R&D collaboration are the crucial factors to promote operational performance of the firms locating in Korean health industry clusters. It is important that this study has been investigated with the firms of health industry developing economy of a nation.
