This paper attempts to investigate the tonal implementations of English stress clash, arguing that a preceding stress shifts leftward when two lexical stresses conflict across word boundaries or that H* and L* pitch accents are alternatively manifested on the stressed syllables, establishing intonational peak and valley contours. We claim that the H*/L* alternation might be a tonal strategy to avoid stress clash, and that pitch could be solely manipulated to display a rhythmic effect with maintaining lexical stress. In the experiment, we examined two-word combinations whose boundaries involve stress clash, and divided them into two categories. One has the preceding words involving a heavy syllable ahead of stress to guarantee the place for a shifting stress and the other, a light syllable, in which case stress shift is completely prevented. We analyzed the distribution of pitch accents in the word combinations, focusing on the pitch configurations in the cases where stress should not be shifted. Results show that approximately 50% of the stimuli show stress shift in the heavy syllable combinations of the preceding words; the preceding stress is moved leftward within the word. The other 50% and the light syllable combinations show various pitch accents patterns; H* and L* alternation, deaccentuation of either stressed syllable, or L-insertion between two H* pitch accents, etc. We interpret this as a rhythmic effect of tone to avoid stress clash and suggest that a true stress clash would be confined into cases without H*/L* contours.

An understanding of store patronage behavior is a critical issue for retail managers, especially when it comes to a new kind of retail store, as it enables them to identify and target potential customers. Reflecting this managerial need, this study is focused on the fashion multi-brand shop, specifically investigating its store attributes, customers' shopping orientation, and store patronage. Accepting the shifting marketing paradigm from 4P's marketing mix to 7P's marketing mix, the 7P's marketing mix is employed in this study to measure the store attributes, including people(sales oriented and customer oriented), price, place, promotion, physical environment, process, and product. The store attributes significantly influencing patronization are found as customer oriented sales people, product, physical environment, and process. The shopping orientations of the customers, 222 female adults aged from 20s to 40s are found as ostentatious, pleasant, fashion pursuant, rational, and addictive. The consumers who are ostentatious, pleasant, and fashion pursuant are highly likely to be patronize to the fashion multi-brand shops.

Although it is well documented that patients with cochlear implant experience hearing difficulties when processing their first language, very little is known whether or not and to what extent cochlear implant patients recognize segments in a second language. This preliminary study examines how Korean learners of English identify English segments in a normal hearing and cochlear implant simulation conditions. Participants heard English vowels and consonants in the following three conditions: normal hearing condition, 12-channel noise vocoding with 0mm spectral shift, and 12-channel noise vocoding with 3mm spectral shift. Results confirmed that nonnative listeners could also retrieve spectral information from vocoded speech signal, as they recognized vowel features fairly accurately despite the vocoding. In contrast, the intelligibility of manner and place features of consonants was significantly decreased by vocoding. In addition, we found that spectral shift affected listeners' vowel recognition, probably because information regarding F1 is diminished by spectral shifting. Results suggest that patients with cochlear implant and normal hearing second language learners would experience different patterns of listening errors when processing their second language(s).

Objective : To obtain more reliable sample in stereotactic biopsy, authors adopted proton chemical shift imaging ($^1H$-CSI)-directed biopsy. Until now, proton single voxel spectroscopy($^1H$-SVS) technique has been reported as a technique using metabolic information in stereotactic biopsy. The authors performed $^1H$-CSI with a stereotactic headframe in place and evaluated the pathologic results obtained from local metabolic information through $^1H$-CSI. Methods : $^1H$ CSI-directed stereotactic biopsy was performed in four patients. $^1H$-CSI and conventional Gd-enhancement stereotactic MRI was done simultaneously after application of the stereotatic frame. After reconstruction of metabolic maps of NAA/Cr, Cho/Cr, and Lactate/Cr ratios, the focal areas of increased Cho/Cr ratios and decreased NAA/Cr ratios were selected for target sites in the MR images Results : There was no difficulty in performing $^1H$-CSI with the stereotactic headframe in place. In pathologic examinations, the samples taken in area of increased Cho/Cr ratios and decreased NAA/Cr ratios showed the features of increased cellularity, mitoses and cellular atypism, thus facilitated the diagnosis. The pathologic samples taken from the area of increased Lactate/Cr ratios showed prominent feature of necrosis. Conclusion : $^1H$-CSI was feasible with stereotactic head frame in place. The final pathologic results obtained in our samples were concordant with the local metabolic informations from $^1H$-CSI. Authors believe that $^1H$ CSI-directed stereotactic biopsy may provide us advantages in obtaining more reliable tissue specimen in stereotactic biopsy.

The purpose of this study is to aesthetically approach a game, which was popular at home, through microscopic analysis on World of Warcraft. World of Warcraft(hereunder called WOW), which improved a game method of MMORPG that had been popular conventionally at home, from several angles, is suggesting new paradigm of MMORPG game. This study aims to propose new vision on game analysis by approaching this new method from the perspective of player. For this, it divided WOW into shift method, instruction implementation method, and communication configuration method, and analyzed this, respectively, by introducing a concept of empty time, empty space, and non-place, which was borrowed from Zygmunt Bauman's "Liquid Modernity". WOW's shifting method rather extends empty time, that is, the waiting time, contrary to the conventional MMORPG, which used a method of removing. Instead of maximally reducing boring, which becomes disturbance of a game, it is what overwhelmingly enlarges time that needs to be waited, thereby being what induces a sense of time, which a player experiences daily life, to the inside of a game. WOW's instruction implementation method offers one of hugely single map instead of zone-system necessary for map loading in the discontinued form. This minutely implements even a greatly insignificant place in playing a game, thereby stirring up a sense of travel, which explores there in reality. Finally, WOW's community configuration method makes a hunting-targeted group clear, which added a concept of hunting called the raid to the existing gild system. The raid, which is a large party of being bound to the inside of Instant Dungeon, clearly gives a performance role to each of party members, thereby allowing the identity in character to be connected directly to the identity of player. Through this, the player filled the suggested 'space' with experience, thereby being able to change it into 'place' that is significant to an individual.

Within a context of rapid technological change and shifting market conditions, the education environment requires new paradigm of education delivery. In accordance of such a technological progress, distance education system, which makes the learning take place at anytime anywhere, overcoming barriers of time, or distance, is emerging as a mainstream of education delivery replacing the convectional one way delivery system from instructor to learners. This paper aims to introduce the development principle and algorithm about Instructional System Desgin(ISD) module, a part of a total solution for distance education services. It was developed on Linux, a free Unix-type operating system. Linux supports so various network protocols, sharing the network resources in a smooth way, that it is able to integrate with other operating system very easily, especially with Windows NT or Windows 2000 servers. In terms of quality, it never falls behind the windows products which are commercially available only. It is a right operating system for the such a school environment that is usually limited in budgets. The development environment of the distance education solution to which ISD module belongs is composing of Apache server for web server, lava bean based on components for ISD module, PHP, server-side scripting language, for HTML documents and MySQL for DBMS.

Mobile shopping, through the use of the smart phone, has become a very popular shopping method for consumers due to it not being limited by time or place. This research aims do the following:1)find the causes for consumers shifting to mobile shopping with the focus on fashion and beauty items; and in order to so, this research will use the TAM that was found by David et al (1989), and 2) distinguish any behavioral differences between consumer groups divided into purchasing intention of fashion and beauty items through smart phone. Path analysis was performed to verify the cause-and-effect relationship between the variables. Personal characteristics(i.e. market maven, time orientation), perceived usability, ease of use, attitude towards mobile shopping, and purchase intentions were all treated as dependant variables. The results showed that attitude towards mobile shopping was the most important variable on mobile shopping intentions. Time-oriented and Market Maven were thought to affect mobile shopping attitude and the dependent variables of purchase intention. Also, when purchasing smart phones, consumers highly valued smart phone's popularity; people with higher purchasing intention mainly used entertainment and utility apps. The following are the main reasons for not purchasing through mobile shopping: they are slower than computers, inconveniences in viewing due to small size of the screen, and security issues. The consumers used the internet as their main source of acquiring daily information. In this research, factors that affect the purchase intention were studied. However, it is difficult to firmly insist that this research correctly predicts the actual purchase intention-further studies need to be done to investigate the relationship between mobile purchase intention and actual purchase intention.

This paper relates with the robustness performance improvement of QE-MMA (Quantized Error-MMA) adaptive equalization algorithm based on the dithering in order to reduce the intersymbol interference by nonlinear distortion occurs at channel. The QE-MMA was appeared for the easiness of H/W implementation in place of multiplication to shifting in the tap coefficient updates applying the power-of-two operation to the magnitude of error signal in currently SE-MMA, it's performance were degraded by this. For improving it's performance, the proposed DQE-MMA adds the dither signal which has constant statistical characteristics in the prestage of power-of-two operation. It was confirmed by simulation that the DQE-MMA gives better robustness performance than current QE-MMA in the same channel and signal to noise ratio.

This study empirically examines how asymmetric price adjustment of the retail gas price happens differently for various oil products, such as high-grade gasoline, regular gasoline, and diesel, by employing asymmetric error correction model within weekly data set from 2010~2015. Our estimation results show that the price adjustment, across the all oil types, predicated on shifting crude oil and wholesale oil prices is asymmetric. In addition, the duration of asymmetry was shorter in high-grade gasoline case than in other oil types. This took place by rapid price adjustment of high-grade gasoline price when faced with both cost increases and decreases, in comparison with regular gasoline and diesel cases. There results were attributed by characteristics of the consumer group and a high retail-wholesale margin of high-grade gasoline.
