Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

Background: More than 1 million cancer survivors reside in Korea. We here investigated activity limitations of cancer survivors compared to controls without a history of cancer. Materials and Methods: Using the 4th and 5th Korea National Health and Nutrition Examination Survey (2007-2012) data, we identified 1,155 adult cancer survivors. Activity limitations were defined as limitation in activities of daily living, experience of lying in a sickbed, and number of days lying in a sickbed during the last month. Descriptive analysis and multiple logistic regression compared these measures for survivors and controls by sex and age groups. Results: Approximately 29.4% of cancer survivors reported limitation in activities of daily living, 14.6% experienced lying in a sickbed, and 4.3% experienced more than 15 days lying in a sickbed during the last month. After controlling for demographic and health-related factors, cancer survivors were more likely to report activity limitation than controls. The associations were similar across sex and age groups. Conclusions: Cancer survivors have increased activity limitation compared to controls and these limitations persist across sex and age. Targeted interventions and improved management are essential for improving cancer survivor daily life.

It has been observed that the linear relationship between the logarithm of bioconcentration factor (log BCF) of highly hydrophobic chemicals and their log $K_{ow}$ breaks when log $K_{ow}$ becomes greater than 6.0. Consequently, super hydrophobic chemicals were not thought to cause baseline toxicity as a single compound. Researchers often call this phenomenon as "hydrophobicity cutoff" meaning that bioconcentration or corresponding baseline toxicity has a certain cutoff at high log $K_{ow}$ value of hydrophobic organic pollutants. The underlying assumption is that the increased molecular size with increasing hydrophobicity prohibits highly hydrophobic compounds from crossing biological membranes. However, there are debates among scientists about mechanisms and at which log $K_{ow}$ this phenomenon occurs. This paper reviews three hypotheses to explain observed "cutoff": steric effects, kinetic or physiological limitations, and chemical activity cutoff. Although the critical molecular size that makes biological membranes not permeable to hydrophobic organic chemicals is uncertain, size effects in combination with kinetic limitation would explain observed non-linearity between log BCF and log $K_{ow}$. Chemical activity of hydrophobic chemicals generally decreases with increasing melting point at their aqueous solubility. Thus, there may be a chemical activity cutoff of baseline toxicity if there is a critical chemical activity over which baseline effects can be observed.

PURPOSE: This study is a data analysis study to determine the physical health problems and reasons for disabilities and activity limitation rates that limit daily life and social activities among the elderly population aged 75 or older in Korea. METHODS: This study data was extracted from the raw data of the 7th National Health and Welfare Survey (2016-2018). The subjects of this study were 1,995 elderly people (823 men, 1,172 women) aged 75 years or older. The collected data were analyzed using frequency analysis and logistic regression analysis. RESULTS: From 2016 to 2018, the activity limitation rate among the elderly population aged 75 or older in Korea was 20.6% for men, 24.6% for women, and 23.1% overall. The three major diseases with the highest frequency of activity limitations were back and neck problems (36.5%), arthritis and rheumatism (28.7%), and knee and leg pain (14.7%). Activity limitation due to old age was found to be 13.1%, making it the fourth most frequent reason. The rate of activity limitations due to mental retardation and obesity was found to be 0%. The three major activity limitation rates were significantly related to gender. CONCLUSION: The main diseases causing activity limitations among the elderly population aged 75 or older in Korea were back and neck problems, arthritis and rheumatism, and musculoskeletal diseases such as knee and leg pain. Therefore, it is believed that it can be used as basis data for reducing the activity limitation rate of the elderly population in the aging era.

근로능력은 장애인소득보장정책과 장애인고용정책에서 정책대상자를 선정하는 핵심요인이다. 우리나라에서 사용하고 있는 근로능력평가지표인 장애등급은 의학적 손상에 기초하여 결정되는 것으로, 제대로 근로능력을 평가하지 못한다는 비판을 받고 있다. 이 연구에서는 장애등급, ICF 활동참여수준, 일상생활도움필요정도 및 자기평가건강상태의 4 근로능력평가지표들이 장애인의 취업여부에 대한 설명력을 비교함으로써 가장 적절한 평가지표를 찾아 내고자 하였다. 그 결과, ICF 활동참여수준이 장애인의 취업여부에 대한 설명력이 가장 높았으며, 이어서 일상생활도움필요정도, 장애등급, 그리고 자기평가건강상태의 순으로 나타났다. 결론적으로 장애인연금제 및 장애인고용정책 등에서 적절하게 활용할 수 있는 근로능력평가지표는 ICF 활동제한 및 참여제약 영역에 해당하는 지표들이라고 할 수 있다. 따라서 ICF 활동제한 및 참여제약 영역을 바탕으로 한 근로능력 평가지표가 장애등급보다 더 적절한 근로능력평가지표라고 할 수 있을 것이다.

The concept of a 'place' in contemporary cities has been fundamentally challenged by the social, economical changes as well as the global digital network. The complex and multi-layered contemporary everyday life blur the boundaries of the existing architectural programs. In contemporary architecture, various proposals have attempted to overcome the physical limitations. 'Activity Diagram' is one of them. Activity diagram is a diagrammatized design process In which the given program is analyzed into individual activities, then it is re-organized and finally spatialized based on the analysis. In many projects by Manuel Gausa, Ben Van Berkel and Vicente Guallart, the activity diagram is applied in various forms and they are explained with theoretical backgrounds. Based on how the given program is re-organized into assembly of activities and how diagram is applied, five analytical elements were selected to critically analyze three chosen architects' case projects. In this study, it is found that architects attempt to construct an open networked world where diverse activities are freely interconnected in spite of some fundamental limitations of activity diagrams.

PURPOSE: The objective of this study was to provide a basis for the need to apply psychological factors-based rehabilitation programs to osteoarthritis patients by understanding how the limitations on the activities of osteoarthritis patients relate to the health-related quality of life and depression. METHODS: This study assessed 1,994 osteoarthritis patients from the 7th Korea National Health and Nutrition Examination Survey (KNHANES, 2016-2018). The subjects were divided into two categories: with activity limitation and without activity limitation. A Chi-square test and logistic regression analysis were conducted. RESULTS: The EQ-5D index of subjects with activity limitation was .84 ± .16, it was .94 ± .12 in those with no activity limitation (p < .05). The diagnosis of depression was 16.8% and; 8.3% in those with and without activity limitation, respectively (p < .05). There was a significant difference in the odds ratio for each item in the EQ-5D. Moreover, the odds ratio for depression with an activity limitation was 2.171 (1.512 - 3.118) compared with no activity limitation. CONCLUSION: The activity limitation of osteoarthritis patients reduces the health-related quality of life significantly and increases the probability of depression. Therefore, the treatment of osteoarthritis patients should be approached considering the psychological conditions. Moreover, early diagnosis of depressive symptoms is needed to prevent symptom deterioration and increase the compliance with rehabilitation therapy.

The existing GOMS model overestimates the performance time of mouse activities because it describes them in a serial sequence. However, parallel movements of eye and hand(eye-hand coordination) have been dominant in mouse activities and this eye-hand coordination is the main factor for the overestimation of performance time. In this study, therefore, the revised CGOMSL model was developed to implement eye-hand coordination to the mouse activity to overcome one of the limitations of GOMS model, the lack of capability for parallel processing. The suggested revised CGOMSL model for drag activity, as an example for one of mouse activities in this study, begins visual search processing before a hand movement but ends the visual search processing with the hand movement in the same time. The results show that the revised CGOMSL model made the prediction of human performance more accurately than the existing GOMS model. In other words, one of the limitations of GOMS model, the incapability of parallel processing, could be overcome with the revised CGOMSL model so that the performance time should be more accurately predicted.

The accuracy of training-based activity recognition depends on the training procedure and the extent to which the training dataset comprehensively represents the activity and its varieties. Additionally, training incurs substantial cost and effort in the process of collecting training data. To address these limitations, we have developed a training-free activity recognition approach based on a fuzzy logic algorithm that utilizes a generic activity model and an associated activity semantic knowledge. The approach is validated through experimentation with real activity datasets. Results show that the fuzzy logic based algorithms exhibit comparable or better accuracy than other training-based approaches.
