This study investigated the luxury supply chain management called 'See now, Buy now'. This has been a new way of controlling the supply and demand for luxury brands in the fashion industry since 2016. In this study, we explored the backgrounds and impacts of 'See now, Buy now' in the digital era. 'See now, Buy now' was launched by the fashion brand, Burberry in February 2016. It was the first luxury brand to showcase its entire collection using 'See now, Buy now' among the brands which showcase in Paris, Milan, New York, and London fashion weeks. That has not only caused many controversies in the fashion world but also generated followers. In this study, we analyzed 'See now, Buy now' in three aspects, economics, efficiency, and management strategy, and this was done through a literature survey on articles pertaining to 'See now, Buy now' and empirical surveys on Burberry's collections. Based on 'See now, Buy now', Burberry tried a new process of supply and sale. In the era of SNS, the spread of information is getting faster. The speed of SNS and changes in the fashion market combining IT and mobile technology are major changes faced by the fashion industry. 'See now, Buy now', a model of the new supply and demand in luxury fashion brands, should be noted as a new directional aspect for the future of the fashion industry. Since it was a relatively recent trend that started from the September show of Burberry in 2016, there was still a lack of academic discussion or prior research on this phenomenon. Therefore this study aimed to predict future directions by recognizing the importance of 'See now, Buy now' in the fashion industry. Also, based on this research, the significance of this study was to present a management strategy that applies 'See now, Buy now' to the future of the fashion industry in the digital era.

슈퍼컴퓨터를 대신한 NOW는 고성능 계산작업의 대안으로 대두되고 있다. 일반적인 NOW 환경은 동일 성능의 노드들이기 보다 이질적인 노드들로 구성되어 있다. NOW 환경에서의 성능은 각 노드의 계산능력, 통신시간에 좌우될 수 있고 그밖에 전체 수행시간 관점에서 작업을 분할하는 방법 또한 중요한 요소 중 하나이다. 본 논문에서는 이질적인 성능을 가진 노드들로 구성된 NOW 환경을 고려한 적응적인 브로드캐스팅 방법을 제안하고, 그 밖에 성능 향상에 영향을 미치는 요소들을 성능평가를 통한 분석을 한다. 성능평가는 이질적인 노드들로 구성된 NOW 에서 LAM/MPI를 이용하여 측정하였다.

NOW(Network of Workstations) is considered as a platform for running parallel programs by many people. One of the fundamental problems that must be addressed to achieve good performance for parallel programs on NOW is the determination of efficient job scheduling policies. Currently most research on NOW assumes that all the workstations in the NOW have the same processing power. In this paper we consider a NOW in which workstations may have different computing power. We introduce 10 classes of space sharing-based scheduling policies that can be applied to the NOW with heterogeneous computing power. We compare the performance of these scheduling policies by using the simulator which accepts synthetically generated sequential and parallel workloads and generates the response time and waiting time of parallel jobs as performance indices of various scheduling strategies. Through the experiments the case when a parallel program is partitioned heterogeneously in proportion to the computing power of workstations is shown to have better performance than when a parallel program is partitioned into parallel processes of the same size. When the owner returns to the workstation which is executing a parallel process, the policy which just lowers the priority of the parallel process shows better performance than the one which migrates the parallel process to a new idle workstation. Among the policies which use heterogeneous partitioning and process priority lowering, the adaptive policy performed best across the wide range of inter-arrival time of parallel programs but when the load imbalance among parallel processes becomes very high, the modified adaptive policy performed better.

An experimental study has been conducted to investigate the heat/mass transfer characteristics within a square film cooling hole with asymmetric inlet now condition. The asymmetric inlet now condition is achieved by making distances between side walls of the secondary now duct and the film cooling hole different; one side wall is $2D_h$ apart from the center of the film cooling hole, while the other side wall is $1.5D_h$ apart from the center of the film cooling hole. The heat/mass transfer experiments for this study have been performed using a naphthalene sublimation method and the now field has been analyzed by numerical calculation using a commercial code. Swirl now is generated at the inlet region and the heat/mass transfer pattem with the asymmetric inlet now condition is changed significantly from that with the symmetric condition. In the exit region, the effect of mainstream on the inside hole now is reduced with the asymmetric condition. The average heat/mass transfer coefficient is higher than that with the symmetric condition due to the swirl now generated by the asymmetric inlet condition.

Recently, instead of a high-cost supercomputer, there haws been widely used a NOW system that consists of low-cost PCs and workstations connected all over the network In a NOW, performance for parallel processing depends on the computation pouter of each computer and communication time. Currently, a lot of methods have been proposed in order to increase the performance of parallel processing. However, the previous results have been studied in the view of balancing work load as the computation pouter of each computer. If a computer has multiple work precesses in a NOW, we can predict a decrease of communication tire needed in message passing, Therefore, in this paper, we analyzes factors of improving the performance in the view of work precesses, and evaluates experimently an effect on total performance as the number of work processes increases. Also, we propose a new broadcasting method to be used in experiment of this paper. This paper uses the LAM/MPI for an experimental evaluation.

Many studies make us difficult for understanding the specific concept of NOW avant garde by misusing avant garde or by using the over wide-ranging concept. The purpose of this study is to define the concept of NOW avant garde fashion by analyzing its fashion and its paradigm characteristics, after considering modern avant garde fashion history. This study was used with bibliographic research as well as internet search of qualitative method for analyzing fashion show clothes since 2005 women's wear. The characteristics of NOW avant garde fashion are classified into plural deconstructivism, econonism that integrates the last avant garde factors with logical economics, and the aesthetic of Tech-Human. To conclude, the concept of NOW avant garde fashion is defined as the fashion expressing either the digital-hybrid images or the deconstructive images meaning elimination, unification or confinement, being pilled up one on another, bizarre connection, transposition, and distortion.

Not fully satisfied with the treatment of the so-called two nows in Korean by Lee & Choi (2009), this article seeks to furnish the issue with a firmer ground to base on in the relevant conversation. A close comparison between now and cikum appearing in the present perfect and present tense results in the two findings that (i) a crucial difference between the two adverbs is that Korean cikum lacks English now's ability to be identified with the reference time and (ii) further, seeming differences between them are not real but in fact due to tense and aspectual discrepancies between English and Korean. Thus, it claims, contra Lee (1976) and Park (2004), that cikum is a temporal locating adverb which invariably locates the event time of a given eventuality at the utterance time. In particular, it motivates that a past-tensed sentence with cikum should be understood as holding in the recent past mainly from pragmatic inferences rather than semantic entailments.

In the last few years, a new type of synchronous social networking services (SNSs) has emerged—social live streaming services (SLSSs). Studying SLSSs is a new and exciting research field in information science. What information behaviors do users of live streaming platforms exhibit? In our empirical study we analyzed information production behavior (i.e., broadcasting) as well as information reception behavior (watching streams and commenting on them). We conducted two quantitative investigations, namely an online survey with YouNow users (N = 123) and observations of live streams on YouNow (N = 434). YouNow is a service with video streams mostly made by adolescents for adolescents. YouNow users like to watch streams, to chat while watching, and to reward performers by using emoticons. While broadcasting, there is no anonymity (as in nearly all other WWW services). Synchronous SNSs remind us of the film The Truman Show, as anyone has the chance to consciously broadcast his or her own life real-time.
