This study examines how extreme negative rating reviews affect the usefulness of reviews among the factors that affect the usefulness of reviews, and analyzes how the characteristics of reviewers affect the usefulness of reviews in terms of the effects of extreme negative rating reviews on the usefulness of reviews. The results of the analysis were as follows. First, extreme negative reviews were found to have a positive effect on the usefulness of reviews, and H1 was adopted. Second, when extreme negative rating reviews affect the usefulness of reviews, we looked at the adjustment effect of reviewer reputation and found that the adjustment effect of reviewer"s reputation "friend count", "elite index" and "follower count" was statistically significant. H2-1 was chosen. Third, when extreme negative rating reviews affect the usefulness of the review, we looked at the adjustment effect of the reviewer"s expertise and found that the adjustment effect of the reviewer"s "usefulness vote" and "reviewer"s review count" was statistically significant. H2-2 has been adopted. Based on these findings, we would like to provide implications for the management and strategy of future online sales companies.

The purpose of this study is to derive each sub group through market segmentation for overseas senior tourists and to identify their characteristics of each subgroup. The market segmentation was based on motivation for tourism, behavioral characteristics and demographic characteristics which have an important influence on the selection of tourism activity for overseas senior tourists. However, since the data used in the research are measured on a nominal scale, there are limitations of using the existing method of segmentation research. Therefore, we have studied the subdivision using Mixture Model which can solve this problem. As a result of the study, we derived the total number of optimal subdivision markets with derived from the BIC value and statistically significant differences were found in each group. The results of this study are expected to contribute academically to the development of overseas senior tourism in the future and to be used as actual data in the tourism industry.

특집 2 : 개화기 및 현대국어 형성기 국어의 고찰 ; 20세기 초 유성기 음반으로 본 모음 “ㅚ, ㅟ”의 발음에 대하여

조아람 ( A Ram Jo ) 반교어문학회 2014 泮橋語文硏究 Vol.0 No.38

본고는 1920∼40년대 유성기 대중가요 음반의 음성자료를 중심으로 모음‘ㅚ, ㅟ’의 음가를 살피는데 목적이 있다. 본고에서 사용한 자료는 《신나라 레코드》에서 발매한 ‘유성기 대중가요 음반세트’의 CD 23장이다. 총 28명의 가수가 노래한 156곡 중에서 모음 ‘ㅚ’나 ‘ㅟ’를 포함한 297음절을 대상으로 진행하였다. 먼저, 모음 ‘ㅚ’의 경우 주로 /w/계 상향 이중모음으로 가장 많이 발음되었고, 나머지는 단모음 [Ø], [e], [i], [o], [y] 등으로 발음되었다. 단모음 [Ø]는 ‘ㅟ’의 단모음 [y]에 비해서는 많이 발음되었는데, 그중 대부분이 동북지역에서 발음되었다. 반면, 동남지역의 발음은 다른 지역들과 비교하여 가장 여러 가지의 발음을 하고 있다. 모음 ‘ㅚ’는 동북지역 이외의 지역에서는 이미 상향 이중모음의 발음이 절대적으로 우세한 모습을 보였으며, 드물게 단모음 [Ø]가 발음되었고, 선·후행 요소나 개인차에 따라 수의적으로 발음되는 다른 발음들을 볼 수 있었다. 모음 ‘ㅟ’ 역시 /w/계 상향 이중모음으로 가장 많이 발음되었다. 모음 ‘ㅚ’의 발음처럼 [we], [we] 등의 발음도 조금 있었는데, ‘ㅚ’와 다른 점은 하향 이중모음 [uj]의 발음이 적은 수이지만 나타난다는 것이다. 단모음으로는 [y], [i], [u], [e] 등의 발음이 나타나고, 이 중에서 단모음 [y]의 발음은 ‘ㅚ’에서 나타난 단모음 [Ø]와 비교하면 적게 나타난다. 지역적으로는 서북 동북지역에서 각각 두번씩, 서남 동남지역에서 한 번씩 나타나는 등 지역적 차이가 크지 않았다. 모음 ‘ㅚ’는 하향 이중모음([oi/oj])의 발음을 보이지 않은 반면, 모음 ‘ㅟ’는 하향 이중모음([ui])을 보이는 것으로 보아 모음 ‘ㅚ’에 비해 그 음가의 변화 속도가 더디게 이루어졌을 것으로 예상할 수 있다. The studies is to observe the phonetic value of ‘ㅚ’ and ‘ㅟ’ based on audio materials of gramophone records of pop music in the 1920s~1940s. The materials used to this thesis are the 23 compact discs (CD) which were originally recorded on gramophone records released from <Sinnara Records>. I have studied 297 syllables including vowels of ‘ㅚ’ and ‘ㅟ’ among 156 songs which a total of 28 singers sang. First of all, in the case of ‘ㅚ’, it was most pronounced as on-glides with /w/ and the rest of all was pronounced as monophthongs like [ø], [e], [i], [o], [y] etc, including [wi] pronounce like a diphthong of ‘ㅟ’. In comparison with a monophthong [y] of ‘ㅟ’, a monophthong [ø] is more pronounced and most of them were pronounced in the northeast. On the contrary, the pronunciations of the southeast had a variety of ones compared to other regions. A pronunciation of vowel ‘ㅚ’ was already dominated by pronounced on-glides with /w/ throughout the regions except the northeast. In addition, a monophthong [ø] was rarely pronounced depending on phonemes or individual differences. Next, a vowel ‘ㅟ’ was also pronounced most as on-glides with /w/. There were a few pronunciations like [we], [we], as pronounced as a vowel ‘ㅚ’, but the difference with there were pronunciation of an off-glides [uj] though there were a few. The pronunciation like [y], [i], [u], [e] etc, in monophthongs appeared and the pronunciation of [y] among them hardly appeared compared to the monophthong [ø] of ‘ㅚ’. There were not many regional differences as there were seen two times in the northwest and northeast each and one time in the southwest and southeast each. A vowel ‘ㅚ’ wasn`t pronounced as off-glides with /j/ which are [oi/oj]. On the contrary, a vowel ‘ㅟ’ was pronounced as an off-glides /j/ which is [uj]. In light of these, it is experted that a vowel ‘ㅟ’ has been made a slower rate of pronunciation variation than a vowel ‘ㅚ’.

The purpose of this study is to identify the effect of service recovery strategy on post-recovery value, post-recovery satisfaction, and positive WOM according to the type of service failure when medical service failure occurs. Based on these findings, we would like to present effective management measures from the perspective of the manager in the event of a medical service failure. Structural equations and pairwise parameter comparison method were performed for hypothesis testing. The group experiencing technical service failures was shown to have a significant positive effect on the value after recovery of the service recovery strategy (β=0.481) and effort (β=0.648). Therefore, only Hypothesis 1-1 and hypothesis 1-4 were adopted. The group experiencing procedural failure was shown to have a significant positive effect on the value of the service recovery strategy (β=0.724) after recovery. Thus, only hypothesis 1-1 was adopted. Both groups that experienced technical service failures and those that experienced procedural service failures were found to have a significant effect on their satisfaction after recovery. Furthermore, post-recover satisfaction has been shown to have a significant positive (+) effect on positive WOMs. Therefore, both Hypothesis 2 and Hypothesis 3 were adopted. As a result of analyzing the moderation effect of service failure type, service failure type had partial adjustment effect. Thus, Hypothesis 4 was adopted.

Various problems as flood, earthquake, and typhoon occurred recently due to unusual weather, and the world is making effort to fight against climate changes. Not only suppliers, but also tourists are putting effort due to the tourist industry and can reduce carbon emissions that directly cause global warming. For this reason, finding factors that can induce tourists to conduct pro-environmental behavior when traveling became an important challenge in tourism industry. For this reason, this study subdivided elements of theory of planned behavior for climate change awareness into attitude, subjective norm, perceived behavioral control, traveling manner, demographic characteristic, and destination preference. This study used the Mixture regression model to supplement limitations of an existing methodology(k-means clustering) and to find effective and rational segmental market, and intended to classify an optimal segment market by investigating an influencing relationship between planned behavior toward climate change awareness and proenvironmental behavior intention. As a result, this study deduced 4 optimal segmental markets using BIC value, and each segmental market showed a significant difference in contribution rate of theory of planned behavior about climate changes. The results of this study can induce differentiated marketing strategies based on the environmental effects of the travel industry.

현재 국내 철도 관련 무선통신 방식은 노선별로 상이하여 비효율적으로 운영되고 있다. 실제로 관제요원, 열차운전자, 현장 유지보수 요원 간 협업이 어려워 다양한 문제점이 발생하고 있으며, 상이한 철도 무선통신 시스템 간 단절 및 불통 현상, 상용망과 기존철도 무선통신시스템과의 주파수 간섭 및 혼신 등에 따른 철도 운행 중단 및 철도 사고 발생 위험이 존재하고 있다. 이에 미래 철도의 안전 확보 및 수송 효율성 향상을 위한 국가철도 통합무선망 구축 관련 연구가 크게 부각되고 있으며, 이러한 요구에 맞추어 무선통신열차제어연구단에서는 철도전용 통합무선망 연구 과제를 2012년 4월부터 진행 중에 있으며 현재는 통합무선망(LTE-R)에 대한 성능 시험을 대불선에서 2013년 5월부터 실시하고 있다. 본 논문은 국가철도 통합무선망 시험선 구축에 관련된 내용이다.
