Purpose: This study aims to analyze design guidelines for hospice facilities in the US, UK, and Canada focused on design considerations and space requirements, and utilizes them as baseline data for establishing standards for Korean hospice facilities. Methods: Comparative review was carried out to investigate hospice care models, design consideration, and room sizes and requirements for design guideline of hospice facilities in United States, UK and Canada identified on electronic database and review articles, and to examine major characteristics and tendencies of hospice facilities. Results: The hospice care models characteristics in design guidelines is generally largely divided into hospital-based hospice facility, Nursing home-based hospice facility, and daycare hospice. The design considerations in hospice facilities focused on medical efficiency, flexibility, barrier-free environment, person-centered care, and stability. There is also a need for single resident room, rooms for the patient's family, and isolation room for infection control. Implications: it is recommended to establish standards for the installation and operation of required and recommended rooms and considerations when establishing the standards of hospice facilities in Korea. This Study is limited to a simple comparative analysis of the framework of guideline.

This study investigates sound, scenery, and soundscape preferences, which are sensory factors that users feel in a healing forest, comparing the difference in recovery by the soundscape. In the barrier-free, wooden walking path of the National Daegwallyeong Healing Forest, a survey site with five different conditions was selected. Users prefer water sounds the most and places with open views for scenery. For the complex sensation of soundscapes, the most preferred is a space where water sounds can be heard, and either a waterfall or an open view can be seen. A profile of mood states test was use to compare users' psychological recovery by the soundscape. It was found that users felt the most positive mood with water sounds and open views. In addition, users' preference for artificial sounds, scenery, and soundscape was the lowest. In the mood state test, it was found that the artificial soundscape incited the most negative emotions.

Smart phone based navigation applications are very useful in everyday life. Cost-effective and user friendly navigation can be provided to the user by many applications available in market. Using the Smart phone these navigation applications provide accurate navigation for outdoor locations. But providing an accurate navigation underground space such as subway station is still a challenge. It is hence more convenient and appropriate for mobility services if the visitors could simply view the guidance of the subway station on their mobile phone, wherever and whenever it is needed. This study develops a algorithm for indoor navigation with the help of Augmented Reality(AR) and QR marker code from the entrance to the train platform for users. This indoor navigation uses AR and QR maker codes for two purposes: to provide the user link to the subway station location and to provide the current guidance details to the user. This Smart phone algorithm that uses a smart phone optical tool to decode the QR marker to determine the location information and provide guidance to the AR without indoor Maps. This algorithm also provides a module to guide mobility vulnerable to the Barrier Free route to destination.

The foregut epithelium of the last instar larva in the scarab beetle, Allomyrina dichotoma was observed with electron microscopes. The foregut epithelium of the scarab beetle larva is composed of a single-layered squamous absorptive cell. The luminal surface of the epithelium is covered with cuticular intima. The free surface of the squamous cell has a irregular array of microvilli 'brush border', while cell membrans close to the basal lamina are infolded and a lot of mitochondria are concentrated in those processes. The cytoplasm in the epithelial cells is well developed nucleus, mitochondria. And the basal region of cell contains large lipid-, protein droplets and numerous glycogen granules. The basal lamina is located between the basal membrane and muscle bundle, providing barrier between the epithelium and the hemolymph. The epithelium is surround by the subepithelial space and muscles. The subepithelial space, which is composed of fibrous connective tissue is innervated by many tracheoles and axon.

This The purpose of this study is to evaluate user satisfaction with village bathhouses, selected from a two-year pilot project of common facilities for senior in rural areas from 2014 to 2015. A survey was conducted using a questionnaire to evaluate user satisfaction, and 135 questionnaires were collected from 18 common meal facilities. User satisfaction was evaluated in five categories with a five-point scale: location and spatial composition; emotions and intimacy; safety; nutrition; and maintenance and management. The results are as follows. First, when overall user satisfaction was evaluated on a five-point scale, the average score stood at 4.24 out of five points and 90.03 out of 100 points. These findings suggest that users were generally satisfied with the common meal facilities. Among five categories, scores except safety stood at four points or higher, indicating higher user satisfaction. Second, communal meal in rural areas have been carried out already but the environment for communal meal like cooking equipment, wastewater disposal, and space have been poor. However, the environment is improved through this pilot project, which has a positive effect to user satisfaction. Third, space planning for barrier-free or sanitary in storage of food containers are not adequate, which is necessary to detailed planning and concrete guideline.

Purpose: Recently, the number of severely mentally ill patients has been increasing rapidly in Korea, but there are no design guidelines for spatial planning of Korea's acute psychiatric wards. The study aims to clarify the areas and required rooms in Korea's acute psychiatric wards which are important in establishing the design guidelines for Korea's acute psychiatric wards. Methods: This study proposed a structural framework based on the results of investigating and analyzing the acute psychiatric ward guidelines in the UK, Australia, and the U.S. and the areas and the required rooms of the wards stipulated in the basic data for establishing acute psychiatric ward design guidelines in Korea. The design guidelines for overseas acute psychiatric wards are 'Adult Acute Mental Health' in the UK, 'Adult Acute Mental Health Inpatient Unit' in the Australia, and 'Specific Requirements for Mental Health Hospitals' in the United States. Results: As a result of investigating and analyzing the design guidelines for overseas acute psychiatric wards, the areas of wards applicable to acute wards in domestic psychiatric wards were access, patient, treatment, support, and employee areas. In addition, the required rooms for each area were defined around major considerations such as visibility, convenience, comfort, security, safety, patient observation, barrier-free design, and privacy protection. Implications: The results of the study will be presented as a structural framework and basic data for establishing design guidelines for Korea's acute psychiatric wards, which is still absent.

For the silicon oxide $(SiO_x)$ films prepared by using the facing target sputtering (FTS) apparatus that was manufactured to enhance the preciseness of the fabricated thin-film and sputtering yield rate by forming a higher-density plasma in the electrical discharge space for using it as a thin-film passivation system for flexible organic light emitting devices (FOLEDs). The deposition characteristics were investigated under various process conditions, such as array of the cathode magnets, oxygen concentration$(O_2/Ar+O_2)$ introduced during deposition, and variations of distance between two targets and working pressure. We report that the optimum conditions for our FTS apparatus for the deposition of the $SiO_x$ films are as follows: $d_{TS}\;and\;d_{TT}$ are 90mm and 120mm, respectively and the maximum deposition rate is obtained under a gas pressure of 2 mTorr with an oxygen concentration of 3.3%. Under this optimum conditions, it was found that the $SiO_x$ film was grown with a very high deposition rate of $250{\AA}$/min by rf-power of $4.4W/cm^2$, which was significantly enhanced as compared with a deposition rate (${\sim}55{\AA})$/min) of the conventional sputtering system. We also reported that the FTS system is a suitable method for the high speed and the low temperature deposition, the plasma free deposition, and the mass-production.

This study aims to examine the existing conditions of elderly housing facilities and to understand the characteristics and types of outdoor living environments utilized by the elderly. To achieve this, this study relied on two methods: a descriptive method of researching publications and related scholastic writings, and an empirical study that included a survey of present conditions and interviews with the elderly and their nursing care providers. Additionally, evaluation of usage patterns and physical traces were carried out in twelve cases. First, the study showed that all of the facilities, which are fixed in particular areas, had difficulty providing spatial diversity that met the needs of residences. This means that these areas lack flexibility. Activity programs were, however, carried out in a lively manner in well-equipped spaces. Second, an evaluation of outdoor living environments showed that basic facilities were more than adequate, in general. Consideration of resident's physical strength and taste, however, was evaluated as low, indicating that facilities and spaces should be considered to reflect the ages, physical capacity, diverse tastes and hobbies of the elderly, as well. Third, examining the usage patterns of outdoor living activities of residents, the purposes of using outdoor spaces of elderly housing facilities were mainly 'to take a walk' and 'to engage in simple physical exercise' and the walkway, simple sports facilities, and building entrances were highly utilized. The importance of outdoor living environments values was a mean of 4.07 and satisfaction was 4.17. This indicates that residents thought that outdoor living environments are very important and currently satisfied with them.

The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

Purpose: There are no clear criteria for slip performance in the BF certification process, so the evaluator relies on subjective judgments depending on the field situation. Physical criteria for determining the slip performance of various floor finishes are not clear. C.S.R., the only criterion currently being used to check slip performance, may raise questions about its coverage, feasibility and reliability. Method: For an analysis of domestic standards and status, KS L 1001, KS M 3510, and KS F 2375. External standards are analyzed for ADA Standard, ANSI Standard, and BS EN Standard. Analyze the test methods and evaluation criteria of O-Y-PSM, BPT, and the dynamic slip resistance test used in these criteria. It also presents an improvement plan for the rational presentation of standards. Results: To date, various kinds of test methods and measuring devices of the slip resistance coefficient have been developed, but there are not many ways to trust useful results related to user safety. Reliability and thoroughly verified test methods and criteria should be used to assess the slip performance of the floor. In order to improve the standard for the evaluation of slip performance in Korea, the existing standard should first be raised to the same level as the overseas standard, and the application of the discriminatory standard should be applied considering the characteristics and usage patterns of each space. Implication: Currently, Korean standards propose various test methods, but the proper use of test methods, scope and assessment criteria are not established, so improvement of the comprehensive standard is necessary.
