This study examines consumers' multi-channel choices in the search phase and purchasing phase stage according to price sensitivity and product characteristics in order to propose a multichannel strategy. For the research, one-way ANOVA, t-test, clustering analysis, and crosstabs are used for the descriptive analysis of 317 surveys on men and women conducted in 2014. The findings are as follows. First, consumers that both experience goods and search goods rely on surrounding advice as well as a search channel regardless of price sensitivity. Second, channel selection differs by price sensitivity when it comes to purchasing phase. Consumers with high price sensitivity tend to purchase from online channels; however, consumers with low price sensitivity tend to purchase from off line channels in cases of search goods. Meanwhile, cases of experience goods have no meaningful result. Third, consumers are divided into 3 groups by the tendency of channel selection. In case of experience goods, search channel choice is aligned with purchasing channel; however, search channel choice is not aligned with purchasing channel in search goods. This study provides clear information on fashion consumers' behavior on multi-channel choices compared to ones for search goods consumers on strategic strategies for fashion companies.

The basic concept for the remodelling of the youthhostel H is to define a rest through the remodelling design. The notion of a rest can be explained better in Chinese character. '休', which means a rest, is the Chinese character that unites two different meanings, the man and the tree or the nature. The intrinsic meaning of a rest,'a man taking a rest under the tree', is applied to the design concept that implies the mutual relationship between the man, the nature and the youthhostel. The design idea for the main areas such as the lobby, the reception, the front, the multi-purposed restaurant and the functionally designed rooms targets the harmony of the aesthetic and the functionality. The diverse space experience which steers the hotel visitors to the reciprocal interrelationship, the exchange of various informations, the comfortable relaxing and the motivation makes it possible to perceive a youthhostel as a space for the various intercourse and the emotional experiences.

It is common practice to display high-quality video images on the large display among the methods of developing tourist attractions and culture in the region as experience contents differentiation is required. This paper combines the local attractions with the OLED dual layer display system and the extended image implementation and augmented interaction technique to give the experiencer a realistic space, such as directing to new experiences and beautiful sights. In this paper, we added UI layer to additional layers of images to enable users to experience sightseeing information, weather, maps, accommodation, festivals and photo materials with images. It is implemented to add fun through interlocking. We also developed transparent OLED and dual layer panel and 3-channel multi-image playback technique.

The purpose of this study is to identify the effect of verbal violence experience by employees on turnover intention and the mediating effect of customer-member exchange(CMX) and job satisfaction in local healthy family support center(HFSC). Additionally, the multi-group analysis and latent mean analysis showed varying results across working for general service and child-care service. For the purpose, study conducted a survey among all the employees at 56 local HFSC in Seoul and Gyeonggi-do Province. Of a total of questionnaires distributed, 319 were returned and analysed. The result of this study were as follows First, verbal violence experience by employees effected on CMX, CMX effected on job satisfaction, job satisfaction effected on turnover intention. Second, CMX and job satisfaction acceptance have statistically significant mediating effects between verbal violence experience and turnover intention. Third, as result of multi-group analysis, the structural relationship were no significant differences found in job position. In the latent means analysis, working for child-care service showed significantly higher latent mean values in verbal violence experience and CMX than general service. Based on the results, policy and practice implications of this study were discussed intervention with considerations given to the difference of the job position.

Purposes: This study tried to extract variables affecting patient-experience satisfaction level in hospital situation, using a multiple-regression analysis and ISA(Revised Importance-Satisfaction Analysis), and to explore variables needed to be improved. Methodology: A mobile-based online patient-experience survey was conducted in eleven general hospitals in A city. To test the validity of this test, this data was compared with the data from Health-Insturance Review and Assessment Service. Then, the standardized regression coefficients extracted from a multiple-regression analysis were used as the importance scale to be used in ISA. Finding: Taken together, the areas with the highest contribution for the in-hospital patient-experience satisfaction level were medication and treatment process and hospital environment. In conclusion, the revised ISA which can show satisfaction and importance both with simultaneously and multi-axis way would be useful in hospital improvement activities. Practical Implications: This study tried to develop a mobile-based patient-experience survey, and to extract the major variables affecting patient-satisfaction level and to identify variables need to be improved. Finally, this should help hostipals to prepare the assessment process with various improvement activities.

We analyze the effects of the sellers' strateiges on the final bid prices in internet auctions. We focus on the following three strategies of the seller adoption of the buy-price, setting the starting bid price, and adoption of 'the effective fixed price' which means that the starting bid price is set near the buy-price. In addition, the number of units sold single-unit or multi-unit, and item characteristics, such as whether the food is a search product (functional product) or an experience product (non-functional product), are also considered. We use real data on bids for 4 items from an online auction site. We find that in an auction for experience products when sold as single units, adopting the buy-price strategy raises the final bid price. We also find that in multi-unit auctions, starting the auction at 'the effective fixed price' raises the final bid price.

Hypertext Transfer Protocol (HTTP) adaptive streaming has become a new trend in video delivery. An HTTP adaptive streaming client needs to effectively estimate resource availability and demand. However, due to the bitrate of the video encoded in variable bitrate (VBR) mode, a bitrate mismatch problem occurs. With the rising demand for mobile devices, the likelihood of cases where two or more HTTP adaptive streaming clients share the same network bottleneck and competing for available bandwidth will increase. These mismatch and competition issues lead to network congestion, which adversely affects the Quality of Experience (QoE). To solve these problem, we propose a video rate adaptation scheme for the HTTP video streaming to guarantee and optimize the QoE. The proposed scheme estimates the available bandwidth according to the bitrate of each segment and also schedules the segment request time to expedite the response to the bandwidth variation. We used a multi-client simulation to prove that our scheme can effectively cope with drastic changes in the connection throughput and video bitrate.

There have been numerous accelerated aging laboratory tests for evaluating suitability of polymeric materials and devices. Aging test for materials and its full scale device has been conducted, but poor correlation of aging test such as service experience were observed. Service experience plays a key role in the utility section of composite insulators. A meaningful and reliable accelerated aging test is needed for evaluating composite insulator. During the service these insulators are subjected to aging stress such as humidity, pollution, and electrical field, and erosion and tracking of the weathershed occurs. This paper presents the criteria of reliability evaluation and evaluation facilities for 22.9 kV suspension composite insulator. We adopt the criteria of reliability evaluation consist of two test methods. One is CEA tracking wheel test for examining the tracking and erosion performance of composite insulator. The other is multi-stress aging test for examining effects of environmental factors such as UV, temperature, humidity, etc on composite insulator.

Nuclear power plant (NPP) operations with multiple objectives and devices are still performed manually by operators despite the potential for human error. These operations could be automated to reduce the burden on operators; however, classical approaches may not be suitable for these multi-objective tasks. An alternative approach is deep reinforcement learning (DRL), which has been successful in automating various complex tasks and has been applied in automation of certain operations in NPPs. But despite the recent progress, previous studies using DRL for NPP operations have limitations to handle complex multi-objective operations with multiple devices efficiently. This study proposes a novel DRL-based approach that addresses these limitations by employing a continuous action space and straightforward binary rewards supported by the adoption of a soft actor-critic and hindsight experience replay. The feasibility of the proposed approach was evaluated for controlling the pressure and volume of the reactor coolant while heating the coolant during NPP startup. The results show that the proposed approach can train the agent with a proper strategy for effectively achieving multiple objectives through the control of multiple devices. Moreover, hands-on testing results demonstrate that the trained agent is capable of handling untrained objectives, such as cooldown, with substantial success.

Purpose - This study investigated xenophobia that has been a serious social problem, and classified multi-cultural groups in Korea into married immigrant, foreign labor workers and foreign students studying in Korea to examine the effects of fixed idea on multi-cultural persons, multi-cultural education experience, multi-cultural sensitivity, good feeling on multi-cultural persons upon social distance with multi-cultural persons, and to find out counteractions and cultural capacity on the xenophobia. Research design, data, and methodology - The study classified multi-cultural persons into married women immigrant, foreign labor worker, and foreign students studying in Korea to examine the effects of their thoughts on cultural cognition. Self-administered questionnaire was used. The subject was college students in Gyeonggi, Gyeongnam and Chungcheong with industrial complexes, more married women immigrants and more foreign students studying in Korea. Results - As shown in the findings, Korean people had different emotion and preference on married immigrant or foreign students studying in Korea and foreign labor workers. Conclusions - This study investigated the effect of multi-cultural person's cultural distance upon xenophobia. Different preference to multi-cultural persons depending upon fixed idea might produce xenophobia, so that the government was demanded to establish various kinds of policies of lives to live life together with immigrant at government level.
