The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

Objectives: The purpose of this study was to investigate the food, nutrient intake, and diet quality of postmenopausal women at high risk of osteoporosis (OP) and cardiovascular disease (CVD) compared with those of control subjects. Methods: A total of 1,131 post-menopausal women aged over 45 years, who took the 2010-2011 Korean National Health and Nutrition Examination Survey (KNHANES), were included for analysis. These participants were classified into the following groups: the OP group, with a risk of OP (n=135); the CVD group, with a risk of CVD (n=373); the OP+CVD group, with a risk of OP and CVD concurrently (n=218); and the control group (n=405) according to bone mineral density (BMD) and CVD risk. Anthropometric measurements, blood profiles, dietary intake, and dietary quality indices were measured and compared among the four groups. Results: Waist circumference, total body fat percentage, blood pressure, fasting plasma glucose, total cholesterol, triglyceride, and LDL-cholesterol were higher, and HDL-cholesterol and BMD were lower in the OP+CVD group than in the control group. In the food frequency questionnaire, the OP+CVD group had significantly higher frequencies of grain (except for multi-grain) and lower frequencies of fruit and dairy product. The frequency of consumption of red meat, processed meat, and carbonated beverages was higher in OP+CVD group. In nutrient density analysis, proteins and vitamin $B_2$ levels were significantly lower in the OP+CVD group than in the control group. The nutritional quality index (INQ) values of calcium were in the order of 0.63, 0.58, 0.56, and 0.55 in each group, and it was urgent to improve the dietary intake for calcium in postmenopausal women. In addition, vitamin $B_2$ was inadequately consumed by all groups. Conclusions: These results suggest that it is necessary to increase the intake of vitamin $B_2$ and calcium and decrease the frequency of intake of red meat, processed meat, and carbonated beverages in postmenopausal women with the risk of OP and CVD.

Facial motor evoked potential (FMEP) by multi-pulse transcranial electrical stimulation (mpTES) can complement free-running electromyography (EMG) and direct facial nerve stimulation to predict the functional integrity of the facial nerve during cerebello-pontine angle (CPA) tumor surgery. The purpose of this paper is to examine the standardized test methods and the usefulness of FMEP as a predictor of facial nerve function and to minimize the incidence of facial paralysis as an aftereffect of surgery. TES was delivered through electrode Mz (cathode) - M3/M4 (anode), and extracranially direct distal facial muscle excitation was excluded by the absence of single pulse response (SPR) and by longer onset latency (more than 10 ms). FMEP from the orbicularis oris (o.oris) and the mentalis muscle simultaneously can improve the accuracy and success rate compared with FMEP from the o.oris alone. Using the methods described, we can effectively predict facial nerve outcomes immediately after surgery with a reduction of more than 50% of FMEP amplitude as a warning criterion. In conclusion, along with free-running EMG and direct facial nerve stimulation, FMEP is a useful method to reduce the incidence of facial paralysis as a sequela during CPA tumor surgery.

This paper aims to evaluate the applicability of dam inflow prediction model using recurrent neural network theory. To achieve this goal, the Artificial Neural Network (ANN) model and the Elman Recurrent Neural Network(RNN) model were applied to hydro-meteorological data sets for the Soyanggang dam and the Chungju dam basin during dam operation period. For the model training, inflow, rainfall, temperature, sunshine duration, wind speed were used as input data and daily inflow of dam for 10 days were used for output data. The verification was carried out through dam inflow prediction between July, 2016 and June, 2018. The results showed that there was no significant difference in prediction performance between ANN model and the Elman RNN model in the Soyanggang dam basin but the prediction results of the Elman RNN model are comparatively superior to those of the ANN model in the Chungju dam basin. Consequently, the Elman RNN prediction performance is expected to be similar to or better than the ANN model. The prediction performance of Elman RNN was notable during the low dam inflow period. The performance of the multiple hidden layer structure of Elman RNN looks more effective in prediction than that of a single hidden layer structure.

The dam reservoir inflow prediction is utilized to ensure for water supply and prevent future droughts. In this study, we predicted the dam reservoir inflow and analyzed how seasonal weather forecasting affected the accuracy of the inflow for even multi-purpose dams. The hindcast and forecast of GloSea5 from KMA were used as input for rainfall-runoff models. TANK, ABCD, K-DRUM and PRMS models which have individual characteristics were applied to simulate inflow prediction. The dam reservoir inflow prediction was assessed for the periods of 1996~2009 and 2015~2016 for the hindcast and forecast respectively. The results of assessment showed that the inflow prediction was underestimated by comparing with the observed inflow. If rainfall-runoff models were calibrated appropriately, the characteristics of the models were not vital for accuracy of the inflow prediction. However the accuracy of seasonal weather forecasting, especially precipitation data is highly connected to the accuracy of the dam inflow prediction. It is recommended to consider underestimation of the inflow prediction when it is used for operations. Futhermore, for accuracy enhancement of the predicted dam inflow, it is more effective to focus on improving a seasonal weather forecasting rather than a rainfall-runoff model.

In the recent marine sector, the development and standardization regarding S-100, which is the universal hydrographical data model standard for development of marine space information, was progressed, and for the effectiveness of marine chart production work and the multi-purpose use of water level data in S-100, S-102(Bathymetric Surface grid) standard development and various studies of BAG formats combined with water level and uncertainty, property information is being progressed. Since the water level information that is important in the operation of the ship is provided based on S-102, the calibration method of the location information when producing S-102 is an important factor in deciding the water level. In this study, the hydrographical surveying was conducted by piloting the standardized method for the production of S-102 in Korea, and have compared the accuracy of water level information according to the GNSS post treatment calibration method. As a result of comparing the water level in 2 places in the rocky terrain of the study area, the northern water level of Namu-do was shown as DL 0.79~0.83m, the eastern water level of Daeho-do was DL 12.63~12.91m, and the horizontal position errors of the intermittent sunshine water level were confirmed to be within 1m. As a result, the intermittent sunshine water level according to the location calibration method when producing the BAG was confirmed that it was in the available range for a ship's safe voyage. However, the accuracy verification for the location of the ship when conducting hydrographical surveying was judged that there is a need for a various additional study about regional characteristics and environment factor.

The purpose of this study was to investigate the usefulness of the cognitive function test tool in the clinical or multi-life environment for the elderly and high-risk demented subjects after the development of the non-clinical dementia early diagnosis test content(Co-Wis) based on the contents of the International Clinical Data Standard(CDISC TAUG-Alzheimer's v 2.0, SDTMIG v3.3) And to verify the validity and reliability of the data. To do this, after searching for dementia diagnosis process, we developed a non-clinical dementia diagnosis content(Co-Wis) that can supplement the shortcomings of the existing paper test. We selected 30 subjects from elders who were over 60 years old and verified the validity of test and the reliability of retest among cognitive domains of the Korean MMSE-K, Seoul Neuropsychological Test(SNSB-II) and non-medication dementia diagnosis content(Co-Wis). As a result, we showed high correlation and reliability in all cognitive domains. However, the limitations of insufficient subjects and regional distribution were identified. Based on the results of the study, we discussed the necessity of supplementing and expanding further studies such as various methods of verifying validity and reliability.
