Recently the study on service robots has been proliferated in many fields, and there are active developments for indoor services such as supporting for elderly people. It is important for robot to recognize objects and situations appropriately for effective and accurate service. Conventional object recognition methods have been based on the pre-defined geometric models, but they have limitations in indoor environments with uncertain situation such as the target objects are occluded by other ones. In this paper we propose a Bayesian network model to reason the probability of target objects for effective detection. We model the relationships between objects by activities, which are applied to non-static environments more flexibly. Overall structure is constructed by combining common-cause structures which are the units making relationship between objects, and it makes design process more efficient. We test the performance of two Bayesian networks for verifying the proposed Bayesian network model through experiments, resulting in accuracy of $86.5\%$ and $89.6\%$ respectively.

Depression and mental illness across all age groups, and steady increasing in suicide rate are our major social problems which cause dramatically decreasing government competitiveness. While Korean government has implemented various policies to improve mental health and prevent suicide, it faces revealing issues in progress on implementation and referral management systems. The current research examined domestic and foreign cases to understand the actual status and directivity of ICT convergence plan in terms of mental health. The United States and the United Kingdom have provided convergent ICT service, telepsychiatric care to senior citizens in rural areas, children and adolescents, socially disadvantaged class, etc. In Korea, emergency-notice devices are installed to prevent suicide for single elderly people, and diverse mobile health devices are developing to cure depression and Alzheimer's disease. ICT convergent mental health care service is needed to save socioeconomic costs and realize universal welfare for an aging society. Social consensus on sharply conflict issues, medical law and medical devices about telepsychiatry service, effectiveness studies on users' unique psychiatric characteristics by life cycle, and region-specialized strategies for the least densely populated rural regions with lower access to medical care should be considered.

This study aims to understand the research trends in visiting nursing through an analysis of 282 research papers published in Korean journals between 1993 and 2018. The number of research papers has consistently increased since 1993 while it slightly decreased in 2014-2018. Of the three types of visiting nursing in Korea, more than 50% of the studies(154, 53.5%) were conducted for hospital based home care services. For the research topics, many studies addressed visiting nursing services(40, 13.8%) and program and technology development of visiting nursing(38, 13.1%). Also, there were many quantitative studies(269, 95.4%) compared to qualitative(9, 3.2%) or mixed methods(4, 1.4%) studies. The study findings suggested the needs for further studies that develop programs for patients and strengthen competencies of visiting nurses. Also, more experimental, qualitative, or mixed methods study designs need to be applied.

The aim of this study was to investigate the association between self-rated oral health, self-rated health, and quality of life (QOL) among older population from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-1, 2016). Data of 1,866 older adults (Mean age 69.5 years) were analyzed with hierarchical logistic regression analyses with IBM SPSS 23.0. Over 87.7% of the subjects rated their oral health as fair or poor. Women and less educated participants more likely to report their perceived oral health as poor (p<.05). Older participants who rated their general health positively were more likely to rate their oral health as good (F=19.04, p<.001). Elders who had bad perceived health (OR: 2.86, 95% CI: 1.5~5.5), had carries in permanent teeth (OR: 2.68, 95% CI: 1.67~4.32) and anxiety or depression (OR: 1.45, 95% CI: 1.42~2.57) had negative oral health perception after controlling for covariates. In conclusion, perceived oral health and QOL were associated with each other in Korean older adults. Therefore, it is recommended to approach holistic strategy for improve health and quality of life in the elderly population.

This study identities various types of subjective perception of hearing-impaired persons on sign language interpretation using Q-methodology in an attempt to explore ways for developing more useful sign language interpretation services for them. For this purpose, 35 statements are extracted based on literatures and in-depth interviews and Q-classification is conducted for 20 interviewees. The results identify a common perception on the provision of sign language interpreter to frequently used institutions of hearing-impaired persons. They also derive three distinguished types of perception: seeking specialization of sign language interpretation, seeking traditional sign language interpretation services and seeking expansion and improvement of sign language interpretation services. Based on the results, the study suggests residence of sign language interpreters in public facilities, improvements of qualification system and education and training courses, specialization by field and improvement of the practice of sign language interpretation services, provision of customized services to the elderly and use of sign language interpreters reflecting the needs of the users.

Objectives : Aconiti Lateralis Preparata Radix (Aconitum Carmichaeli, AC) and Cinnamomi Cortex (Cinnamomi Cortex, CC) have been treated to elderly for kidney yang enhancement in Korean traditional medicine. In this study, the effects of water extract of AC and CC on RANKL (Receptor Activator for Nuclear Factor ${\kappa}B$ Ligand)-induced osteoclast differentiation were evaluated in culture system. Methods : MTT assay was used to evaluate the potential cytotoxicity of AC and CC extracts in bone macrophage marrows (BMMs) stimulated with M-CSF. TRAP (tartrate-resistant acid phosphatase) staining and TRAP activity were performed to know the inhibitory effect on osteoclast differentiation. The protein expression levels of nuclear factors such as activated T cell(NFAT)c1, c-Fos, MAPKs and ${\beta}$-actin in cell lysates treated with AC and CC extracts were analysed by western blotting. Results : AC, CC extracts and their co-administration inhibited significantly RANKL-induced osteoclast differentiation in BMMs in a dose dependent manner without toxicity. Each AC and CC extracts inhibited the phosphorylation of p38. Also, AC and CC extracts, respectively, inhibited the protein expression of c-Fos and NFATc1 more than Co-administration of AC and CC even if all treatments did. It was observed that RANKL-induced degradation of I-${\kappa}B$ is significantly suppressed by all treatments. Conclusions : Taken together, It was concluded that AC and CC have beneficial effect on osteoporosis by inhibition of osteoclast differentiation. Thus, Atractylodis AC and CC could be a treatment option for osteoporosis.
