Augmented reality(AR) service as one of the representative technologies in the era of the 4th industrial revolution has gotten people's increasing attention. At this time, this study aimed to examine the determinants affecting service satisfaction of the AR-based camera application service by focusing on Naver's service. Several factors that might have influences on satisfaction of the AR-based camera application service were conceived based on the previous literature. And it was tested whether they had influences on satisfaction of the AR-based camera application service or not empirically. The responses of a sample of 312 people who had experienced using Naver's service were collected by means of an online survey and they were analyzed employing a hierarchical regression analysis. The results of this research indicated that gender as one of demographic variable, perceived interactivity, aesthetic value, trend following motivation as an extrinsic motivation and playfulness as an intrinsic motivation have significant influences on the service satisfaction of the AR-based camera application service. The results in this study have meanings since they can be used as references for AR service providers to develop more satisfactory AR services.

The purpose of this study was to look into the service quality of websites and the attributes of review information thereon as perceived by visitors thereto and to analyze the effect that the service quality of festival websites and informative usefulness of testimonials would have on the satisfaction with use, along with the effect that the satisfaction with use would have on behavioral intention. Based on the results of this study, we intended to present measures that could help strengthen the intention to spread positive word-of-mouth for festivals and to visit a festival through satisfaction with a festival's website. The festival selected to achieve the objectives of this study was the Yeongdeok Snow Crab Festival, which is one of the most renowned local food festivals in the Gyeongbuk region, having been held for 17 consecutive years, and has been selected as the top festival of Gyeongsangbuk-do for 4 consecutive years. We surveyed visitors to Yeongdeok Snow Crab Festival who had searched for information on the Yeongdeok Snow Crab Festival prior to its opening, as well as those who had participated in Yeongdeok Snow Crab Festival before. The results of this study showed that review information on a food festival website, service quality design, adequacy of substance, responsiveness to customers, and system capability were found to have a positive effect on behavioral intention through satisfaction with use. The findings suggest that it is crucial to manage the service quality of websites in order to stimulate interest in, and induce visits to, food festivals.

The Korean bottom trawl survey was conducted using a trawl designed by the National Fisheries Research and Development Institute (NFRDI). The capture efficiency and size selectivity of this trawl for snow crab Chionoecetes opilio was investigated by experimental tows. An auxiliary sampling net (underbag) was attached beneath the trawl net to capture crabs escaping under the trawl footrope. Experimental tows were made by the same vessel speed (3.4 knots) as in the bottom trawl survey, but toing time was shortened from the standard 30 min to 10 min to reduce possible trawl distortion due to the high catch rate of mud and debris in the underbag. In averaged over 17 tows conducted between 110-383 m depth, trawl efficiency of both males and females combined increased from about 10% at 20 mm (carapace width) to about 70% at 100 mm, with a width of 50% capture equal to 78 mm.

In this study, we evaluated physicochemical properties and sensory characteristics of teriyaki sauce made by using the shell, the byproduct of red snow crab. Moisture content was the highest in fried FRC and the lowest in immersed SOC- while viscosity exhibited contrary tendency. The pH was the highest in dried DRC and the lowest in untreated RAC. Chromaticity was the highest in fried FRC for L, a, and b values altogether. Such result was considered attributable to elution of astaxanthin, a fat-soluble dye protein, which affected chromaticity while it underwent pre-treatment by being fried. Salinity was the highest in fried FRC and lowest in immersed SOC. Available solid contents exhibited contrary tendency. The total free amino acid content was the highest in immersed SOC and the lowest in untreated RAC. Contents of essential amino acids and tasty amino acids, the free amino acids, were the highest in SOC, suggesting that savory taste manifested the most noticeably among specimens treated differently by varying methods. The results of preference test showed that SOC, which showed the highest free amino acid content, also showed the highest preference in terms of outwards appearance, fragrance, taste, texture, and overall items of preference. Those results suggested that the immersion of red snow crab shell increased elution of available solid content and tasty components, influencing the preference of overall taste of teriyaki sauce positively, concerning pre-treatment methods. Based on overall results of the experiment in this study, pre-treatment involving immersion would lead to production of teriyaki with excellent nutrition and sensory features in connection with the use of red snow crab shell for manufacturing teriyaki.

The purpose of this study is to investigate how the degree of distribution influences the calibration of snow and runoff in distributed hydrological models using a multi-criteria calibration method. The Hydrology Laboratory-Research Distributed Hydrologic Model (HL-RDHM) developed by NOAA-National Weather Service (NWS) is employed to estimate optimized parameter sets. We have 3 scenarios depended on the model complexity for estimating best parameter sets: Lumped, Semi-Distributed, and Fully-Distributed. For the case study, the Durango River Basin, Colorado is selected as a study basin to consider both snow and water balance components. This study basin is in the mountainous western U.S. area and consists of 108 Hydrologic Rainfall Analysis Project (HRAP) grid cells. 5 and 13 parameters of snow and water balance models are calibrated with the Multi-Objective Shuffled Complex Evolution Metropolis (MOSCEM) algorithm. Model calibration and validation are conducted on 4km HRAP grids with 5 years (2001-2005) meteorological data and observations. Through case study, we show that snow and streamflow simulations are improved with multiple criteria calibrations without considering model complexity. In particular, we confirm that semi- and fully distributed models are better performances than those of lumped model. In case of lumped model, the Root Mean Square Error (RMSE) values improve by 35% on snow average and 42% on runoff from a priori parameter set through multi-criteria calibrations. On the other hand, the RMSE values are improved by 40% and 43% for snow and runoff on semi- and fully-distributed models.

Plant phenology including flowering, leaf unfolding, and leaf coloring in a forest is important to understand the forest ecosystem. Temperature rise due to recent climate change, however, can lead to plant phenology change as well as snowfall in winter season. Therefore, accurate monitoring of forest environment changes such as plant phenology and snow cover is essential to understand the climate change effect on forest management. These changes can monitor using a digital camera system. This paper introduces the detection methods for plant phenology and snow cover at the mountain region using an unmanned camera system that is a way to monitor the change of forest environment. In this study, the Automatic Mountain Meteorology Stations (AMOS) operated by Korea Forest Service (KFS) were selected as the testbed sites in order to systematize the plant phenology and snow cover detection in complex mountain areas. Multi-directional Internet Protocol (IP) camera system that is a kind of unmanned camera was installed at AMOS located in Seoul, Pyeongchang, Geochang, and Uljin. To detect the forest plant phenology and snow cover, the Red-Green-Blue (RGB) analysis based on the IP camera imagery was developed. The results produced by using image analysis captured from IP camera showed good performance in comparison with in-situ data. This result indicates that the utilization technique of IP camera system can capture the forest environment effectively and can be applied to various forest fields such as secure safety, forest ecosystem and disaster management, forestry, etc.

Recently, the small-scale local governments of japan are enlarging and enriching the service of health, medical and welfare facilities for the elderly . Intensive arrangement of the three types of facilities is one of the effective ways especially for the small-scale local governments. The service network between facilities benefits by the intensive arrangement. Benefits include the network of the medical service, the share of care information, the share of space and equipment. It can be a notable feature in the intensive arrangement that the elderly were taken from welfare facilities (especially dayscare center) to hospital of high movement frequency quickly. Instead of EV path as possible, It is desirable to stand close between facilities of high movement frequency. For large area, the heavy snow made low daycare ratio. Therefore, it is desirable to construct a branch office at a long distance.
