The purpose of this paper is to examine empirically how to balance advertising expenditure before and after launch with regard to the direction of word of mouth in the motion picture industry. The vector auto-regression model is applied to assess the dynamic impact of advertising and word of mouth on sales. Empirical data, including advertising, word of mouth, and sales (the number of entries) of 83 movies are used for analysis. The research results show that for a movie having more positive word of mouth in the pre- and post-launch periods, it is worthwhile to spend the advertising budget in the pre-launch period only and to spare it in post-launch period. However, it is worthwhile to spare the advertising budget in the pre-launch period for movies having less positive word of mouth before and after launch, and to concentrate spending in post-launch period instead. Mangers who handle products and services facing shortened lifecycles, such as games, eBooks, and digital music contents, need to check the quality of pre-launch word of mouth for their advertising budget decisions in the pre- and post-launch periods and spend more of the advertising budget in the post- (pre-) launch period if pre-launch word of mouth is negative (positive). For products and services with a shortened lifecycle, it is recommended to spend more of the advertising budget in the post- (pre-) launch period if pre-launch word of mouth is negative (positive).

Digital radio data is composed of groups which are divided into 4 blocks of 26 bits. And each block is made up of information word and check word. Check word of digital radio data that is composed ofcode word and offset word is used for group/block synchronization and error correction. In this paper, we have investigated the group/block synchronizer using offext word and shortened cyclic decoder for correcting error produced during the radio data transimission. Also, we have simulated the decoding process of the proposed decoder. From the simulation results, we have confirmed that the proposed decoder most with the required coding capcbility.

Nowadays, computer-mediated communications such as chatting and e-mail are widely used in younger generation. It has been known that the communicating words used by on-line users (so-called netizens) are quite different from those used by ordinary people. That is, the words are generally characterized by shortened, mimetic and onomatopoeic words, and the netizens also use various types of emoticon expressed like signs or symbols. This can cause some orthographic as well as cultural problems. This paper investigates some statistical data in PC-based communications, analyzes the general characteristics, and provides some explanations.

The Series RC load is connected with the word line in an attempt to select with high speed the information from the coincident current magnetie memory core. By taking the small time constant of the RC load, the cycle time of the output pulse is shortened by about 2 microseconds to 3 micro seconds. For this purpose, the analytical study are accomplished and the optimum circuit parameters are determined. Furthermore, the thermal problems occuring from the high speed switching of the magnetic memory core have been clarified.

Radio data system is a next-generation broadcasting system of digital information communication which multiplexes the digital data into the FM stereo signal in VHF/FM band and provides important and convenient service features. And radio data are composed of groups which are divided into 4 blocks with information word and check word. In this paper, radio data receiver is developed which recovers and process radio data to provide services. Then we confirm that 7dB SNR is required to be 10S0-5TBER of demodulation. Deconding process of shortened-cyclic-decoder has been simulated by computer. Also, the time-compression (by 16 times) method has been adopted for the RDS features post-processing. Via the error probability calculation, simulation and experimentation, the developed receiver system is proved to satisfy the system specification of EBU and implemented by general logic gates and analog circuits.

This research investigated whether inter-word spaces, the spaces between words, can affect the efficiency of Korean-speaking CSL(Chinese as a second language) learners in Chinese reading of Korean-speaking's ability to read Chinese. Through eye movement tracking experiments, CSL learners of different proficiency levels(beginning, intermediate, and advanced) and native Chinese readers were asked to read Chinese sentences with and without inter-word spaces. The tests analysed the participants' fixation counts and the time spent in reading each sentences and also between each words. In terms of the fixation counts and time spent between sentences, the results show that there were no significant difference in participants' fixation counts from reading sentences with and without inter-word spaces. The results also prove that reading sentences with inter-word spaces significantly shortened the reading time for both CSL learners and native Chinese readers. Even for the participants' fixation counts and time duration between each words, participants spent significantly less fixation counts and reading time while reading words with inter-word spaces. The results were more prominent and positive in tests conducted with CSL learners of lower proficiency. This research shows that inter-word spaces in Chinese texts can enhance the efficiency of chinese learners' reading ability.

This study compares the perception of English high tense and lax vowels (/i, I, u, $\mho$/) by English speakers and Korean speakers of English. The four vowels were produced in /hVd/ context by a native speaker of English, and each word's vowel duration was manipulated to range from 170ms to 290ms in 30ms increments. Two English speakers and six Korean speakers of English were asked to listen to pairs of tense and lax vowel words with manipulated vowel durations and to identify the pair by choosing either heed-hid or hid-heed for front vowels and either who'd-hood or hood-who'd for back vowels. The results show that English speakers distinguished tense vowels from lax vowels with 100% accuracy regardless of the different durations, compared to 62% accuracy for Korean speakers of English. Most errors occurred for lengthened lax vowels and shortened tense vowels. The results of this study demonstrate that Korean speakers mainly rely on vowel duration as a cue to discriminate the tense and lax vowels. The theoretical and pedagogical implications of this finding are discussed.

This study was carried out to investigate the sound distortion following the alternation of the palatal plate thickness. For this study, 2 healthy male subjects (24-year-old) were selected. Born in Seoul, they both spoke Seoul dialect. First, their sounds of /na(나)/, /da(다)/, /1a(라)/, /ja(자)/, /cha(차)/, /ta(타)/, without inserting plates were recorded, and then the sounds with palatal plates of different thickness were recorded, successively. The plate was fabricated in 3 types, each palatal thickness being 1.0mm, 2.5mm, dentoalveolar portion 2.5mm, other residual portion was 1.0mm, successively. Each type plates named B, C, D-type, in succession. Series of analysis were administered through Computer(16 bit) to analyze the sound distortions. These experiments were analyzed by the LPC (without weighting, pre-weighting, post-weighting) of the consonants, vowels portion, formant frequency of the vowels and word duration of the consonants. The findings led to the following conclusions: 1. There was no correlation of the distortion rate on the 2 informants. 2. Generally, vowels were not affected by the palatal plate thickness in the formant analysis, however, more distortion was detected in the LPC analysis, especially C, D-type plates. 3. Consonants distortion was more evident in the C, D-type plate. 4. The second formant was most disturbed and reduced in the all consonants with insertion of the palatal plate, especially C, D-type plate. 5. Word duration was shortened in the plate inserted(except /ja/, /cha/), especially C, D-type. 6. It was found that dentoalveolar, hard palatal sounds were severely distorted in plate inserted, and they were mainly affected by the dentoalveolar portion thickness. 7. There was correlation between palatal thickness and consonants quality.

A study on the upper garment of Korean women, JUORI The upper garment of Korean women. JUGORI, is an inherited mode from the ancient clothing style in the various aspects based on the particulars of Korean clothes. The ancient style of clothes is originated from KWAMDUI belonging to inhabitants of Northern Territory of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korea. And it is quite different from Chinese clothes in lineage. However, this unicque mode of clothes has been much influnced by the Chinese culture and also by the climate of Korean penynsula. The changes of the pattern of JUGORI, in a word, is a sign of shortening tendency of size. This tendency of JUGORI is remarkably seen in the shortening of length and other parts are decreased in size. The JUGORI in the ancient age was fallen below the weist of woman, which is similar to Robe, and was worn with band. However, the length of the JUGORI has been gradually shortened, and therefore, GORUM took place of the band. The shortening tendency of JUGORI is seemed to be shown its sign in the initial time of its origin, because there are some evidences that the women in Sylla Dynasty, and this tendency has been much expedited during the period of Koryu Dynasty with influences of Monggorian culture (Won Lynasty of China) The oldest sample for data of JUGORI in nowaday is one the remains of Yi Dynasty, and this sample for data provides all the particulars of the modern pattern of JUGORI. The tendency of JUGORI had been continued even in Yi Dynasty, and at the end of the Dynasty, the clothes was shortened that the women felt inconvenient wearing it in the status of the shortened JUGORI which was even hardly cover the initial time of epoch of modernization induced from the Western civilization, and after 1920s and 1930s JUGORI become a larger tendency. This is a sing of revival of practical use and rationalization of JUGORI become a shortening tendency again, and the size is similar with that of early age of Yi Dynasty. Instead of these similarities, the particulars of modern JUGORI is weighing on much emphasis on curve beauty and expression of experior beauty. The reason is that, together with westernization of clothes, JUGORI became a special pattern of clothes as a traditional Korean women wears. The very thing explaining this pattern of JUGORI is the "ARIRANG DRESS". And there are some fashion using button instead of GORUM and half sleeve JUGORI for summer use which is regarded as a part of improved aspect of life in Korea. in Korea.

SVLIW processor architectures can resolve resource collisions and data dependencies between the instructions while scheduling VLIW instructions at run-time. As a result, long NOP word instructions can be removed from the object code produced for the processor. Thus, the occurrence of cache misses on the SVLIW processor would be lesser than that on the same cache size VLIW processor. Less frequent cache misses on the SVLIW processor would incur less frequent memory access, and thus, the total execution cycles to complete an application would be shortened compared with cases on the VLIW processor. Such a feature eventually compromises effects of longer instruction pipeline stages than those of the VLIW processor. In this paper, we formulate and compare two execution cycle models of the two architectures. A simulation results show that the longer memory access cycles when cache miss occurs, the total execution cycles of SVLIW processor would be shorter than those of VLIW processor.
