Purpose - This study is to identify how the retail regulations influence customer shopping behaviours and furthermore, whether the Store Closing Act really protects independent retailers as well as traditional markets in Korea. Research design, data, and methodology - By adopting frequency analysis and factor analysis method, the research achieved research objectives. Before a field survey, the authors pre-tested the questionnaire developed, based on similar previous articles, and finalized. Amongst the 353 questionnaires distributed, 332 were returned. It means the response rate is 94.5%. Furthermore, available questionnaires are 330. Results - Rather than stimulating customers to more frequently visit public markets, the regulation has provoked new customer shopping behaviours. In other words, some consumers tend to shop in big box retailers before or after a store closing day, whereas others are likely to stop shopping. What is important is that customers do not patronise small retailers and conventional markets, thanks to the Store Closing Act. Conclusions - In order to keep retailers and public markets independent, the researchers suggest that the government should introduce new techniques without impeding the growth of a retailing sector.

This study investigates Korean listeners' perception of the English stop epenthesis between the sonorant and fricative segments. Specifically this study investigates 1) how often English epenthetic stops are perceived by native Korean listeners, given the fact that Korean does not allow consonant clusters in codas; and 2) whether perception of the epenthetic stops, which are optional phonetic variations, not phonemes, could be improved without any explicit training. 120 English non-words with a mono-syllable structure of CVC1C2, where C1=/m, n, $\eta$, 1/, and C2=/s, $\theta$, $\int$/, were given to two groups of native Korean listeners, and they were asked to detect the target stops such as [p], [t], and [k]. The number of their responses were computed to determine how often listeners succeed in recovering the string of segments produced by the native English speaker. The results of the present study show that English epenthetic stops are poorly identified by native Korean listeners with low English proficiency, even in the case where stimuli with strong acoustic cues are provided with, but perception of epenthetic stops is closely related with listeners' English proficiency, showing the possibility of the improvement of perception. It further shows that perception of epenthetic stops shows asymmetry between coronal and non-coronal consonants.

The right to live is the most valuable benefit and protection of the law. And Medical science is the study considering value of life as the top priority. As modern medical science has progressed and expanding lifespan skills have developed, the number of symptom, called a human vegetable, has been also increased. As a result, people concerns whether euthanasia should be permitted. (1) Active euthanasia is prohibited and a doctor who conduct it is punished. (2) Indirect euthanasia can be permitted unless it is against a patient's intention. (3) Permission of passive euthanasia depends on intention of a patient. In other words, when a patient accepts, a doctor respects the right of self determination of patient and irreversible situation such as brain death happens, treatment stop is permitted. Even a patient who is in the last stage of cancer has a right to die in the dignity and elegance. Solutions for ceasing medical treatment are as follows; First, establishment of 'Bioethics Committee'. Second, setting procedures to empower a court a right to decide whether medical treatment is ceased. Third, setting procedure a government to assist treatment fees. In this paper, direction for social agreement of legal policy regarding the ceasing treatment is provided.

In order to operate Internet Banking, there is a important thing to precede, That is to carry out a scheme of one-stop to let clients transact anything they want to buy and establish the preservation of public security system between existing banking networks. (of course, that should be designed handily to the clients). In this paper, the protocol which is determined between banking network and Internet to maintain the preservation of public security. In other words, each XPM(X.25 Packet Manager) is a program to manage both system security and service at each other side; manage all packets which are connected by X.25 protocol. If other condition like law and institution is improved, it will be adopted to real operation with various service. Further more, we tan construct Electronic Commerce and adopt various digital money like electronic coin or check.

The aim of this study is to develop a technique for keyword extraction in Korean-Chinese text in the modern period. We considered a Korean morphological analyzer and a particle in classical Chinese as a possible method for this study. We applied our method to the journal "Sisachongbo," employing proper-noun dictionaries and a list of stop words to extract index terms. The results show that our system achieved better performance than a Chinese morphological analyzer in terms of recall and precision. This study is the first research to develop an automatic indexing system in the traditional Korean-Chinese mixed text.

Speech characteristics of patients with cleft palates are resonance disorders, articulatory disorders and voice disorders. The purpose of this study is to find the acoustic, physiological and articulatory characteristics of cleft palate speakers. Thirteen control groups and 3 cleft palate patients participated in this experiment. Test words were composed of simple vowels and consonants imbedded in low vowel /a/, /p 'ap'i/ and /sasi/ according to the evaluation experiments. CSL, Video fluoroscopy, Fiberscope and Nasometer were used to analyze VOT, vowel formants, profiles of articulator, VP port images and nasalance. The results are as follows : (1) The nasalance of cleft palate patients in the high vowel /i/, stop sounds and fricative sounds were 60%, 34.8% and 44.1%, respectively. These values were higher than those of the control group. (2) Posterior articulatory movements /k'a/ in patients with cleft palates showed backward movement in comparison with the control group on Video Fluoroscopic images and palatograms. These results suggested that patients with cleft palate have the compensatory oral sounds to close the VP port. (3) The VOT in patients with cleft palates was longer than that of the control group.

This study examines the voice onset times (VOTs) of Korean stops produced by Korean learners of English with high language proficiency and long L2 exposure (i.e., Korean-English bilinguals) to assess whether the VOTs of their lax and aspirated stops are merging and, if so, which types of stops are being changed. Thirteen Korean speakers (six female and seven male) who had studied in the USA for more than three to ten years participated. The results show that the speakers in this study with long L2 exposure are participating in the VOT merger, in which VOTs for aspirated stops are reduced while those for lax stops are increased. In other words, change in VOT affects not only aspirated stops but also lax stops. The results indicate that L1 phonetic drift may not be primarily affected by the amount of L2 exposure, and language contact may not be the primary factor triggering a sound change in the Korean stop system. Further study is necessary focusing on the phonetic shift of the "lax" category because it may play a pivotal role in a tonogenetic-like sound change in present-day Korean.

This study examined the acoustic properties of initial stops in Korean, produced by Korean native speakers and English Korean learners. The productions of Korean native speakers were compared with those of beginners and advanced learners of Korean. Fundamental frequency(F0) and Voice Onset Time(VOT) were measured in condition of one or two syllable words, containing word-initial lenis, fortis, and aspirated stops. English Korean Learners showed that they produced stops with relatively shorter VOT and lower F0, compared with those of Korean native speakers. In case of the manner of articulation, English Korean learners have production difficulties in order of lenis stops, aspirated stops, and fortis stops. In regard to the place of articulation, English Korean learners showed production troubles in order of labial stops, velar stops, and alveolar stops. In the experiment of perception, it is hard for English Korean learners to distinguish stops of lenis and aspirated. Therefore, the results of production experiment were almost consistent with those of the perception experiment. Finally, according to both groups of proficiency, the results demonstrated that the advanced learners produce or perceive Korean stops easier than the beginners.

This study examined the production of aspirated stop consonants in Korean and English words to address how the influences differed particularly in terms of proficiency in L2 English. Voice onset times (VOTs) were measured from two American monolinguals and seven Korean speakers. The results showed that VOT patterns for both L1 and L2 stops differed according to their proficiency in L2 English. In L2 English, high proficient speakers produced VOTs that were similar to those of native speakers of English whereas low proficient speakers produced VOTs that were significantly longer than those of proficient speakers. In L1 Korean and L2 English, most of the proficient speakers produced VOTs similarly. Unlike previous findings, Korean VOTs were even shorter than English counterparts. The VOT shortening of aspirated stops in Korean was found for most of the proficient speakers. The findings of the present study suggest that cross language phonetic influences as well as the ongoing VOT shortening in Korean aspirated stops may be correlated with L2 proficiency. Since this is a pilot study with a small number of subjects for each proficiency group, further quantitative study is necessary to generalize.

Why people reduce or stop using social network services(SNS), which are regarded as a mean of relationship and communication, unlike the early trend? To explain the phenomenon, this study tries to predict psychological decision making process of users from perspectives of cognitive dissonance theory. From this perspective, this study attempted an integrative approach that reflected 'User's literacy' indicating the ability of individuals to use SNS, and 'negative mass media influence' such as media reports on side effects or the bad experiences of acquaintances, along with the 3 factors used in the SNS Prior research. This study conducted an empirical analysis by surveying 256 facebook users, and the major findings are as follows:- First, Social-overload, complexity, uncertainty and negative media influence are significantly affect dissonance on the use of SNS. Second, Dissonance on the use of SNS significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. Third, the moderating effect of User's literacy wasn't a significant. This study presents a clue to understand psychological decision making process of use of SNS and a guideline for establishing practical strategies. In addition, it is important to note that this study contributes to expansion of theoretical discussion about usage.
