This paper addresses a feature-based robust watermarking scheme for digital images using a local invariant features of SURF (Speeded-Up Robust Feature) descriptor. In general, the feature invariance is exploited to achieve robustness in watermarking schemes, but the leakage of information about hidden watermarks from publicly known locations and sizes of features are not considered carefully in security perspective. We propose embedding and detection methods where the watermark is bound with circular areas and inserted into extracted circular feature regions. These methods enhance the robustness since the circular watermark is inserted into the selected non-overlapping feature regions instead of entire image contents. The evaluation results for repeatability measures of SURF descriptor and robustness measures present the proposed scheme can tolerate various attacks, including signal processing and geometric distortions.

The objectives of this study are to develop a cosmetic involvement scale focusing on Korean men in their 20s and 30s, verify its validity and examine the characteristics of this group. The results of this study's analyses showed that cosmetic involvement scale could be classified into 5 factors: 'trend & interest involvement', 'prestige sensitivity involvement', 'price and value involvement', 'skin involvement,' and 'obligatory involvement'. Also the cosmetic involvement of the target group was classified into 'amusing high-involvement group', 'rational low-involvement group', and 'obligatory high-involvement group'. This study has significance in showing differences of cosmetic involvement factors by gender and proposing a cosmetic involvement scale of Korean men in their 20s and 30s, which has taken men's distinctiveness into consideration.

The development of the information on the internet brought a lot of changes in the real estate market. Because the real estate has local distinctiveness and individuality household who want to move must to visit place for housing information. But now household use internet real estate information at every decision-moving step and that is able to reduce not only the cost of real estate information but also social benefit like $CO_2$ emissions reduction effect. In this study, I analyzed the effect of $CO_2$ emissions reduction with Seoul household residential mobility data when household take informations from internet real estate site. As increasing a single family who is good at internet service, the effect of $CO_2$ reduction from the development of the Internet real estate information has more increased.

This paper presents results from speech production experiments on English, Korean, and Hindi that compare variation in the acoustic expression of dissimilar phonological laryngeal contrast in stops conditioned by prosodic prominence. Target stops are analyzed from utterance-initial, -medial, and -final positions, with a variation in contrastive focal accent, from the speech data by six male American English speakers, five male Seoul Korean speakers, and five male Delhi Hindi speakers. The results show that prosodic prominence conditions enhanced distinctiveness between contrastive segments in the three languages. The manner in which prosodic prominence and prosodic phrase structure is marked at the level of segmental variation is, however, found to be language-specific to some extent. In addition, a correlation between the size of the phonological inventory and the corresponding acoustic variation was found but the linear correlation was not strongly supported with the findings in the present study.

The study investigates the media distinctiveness between twitter and other social media and describes how product information interpretation and responsiveness by internet users can be affected by the distinctive characteristics of twitter and blog media. The characteristics include relationship formation patterns among users, channel diversity, immediateness of information communication, information flow within media, media credibility, and management cost. Specifically, we statistically tested whether these characteristics are meaningfully differentiated by users. Results also showed that users perceived product information processing level and product evaluation direction differently based on these media characteristics. The current findings can serve as a pioneering work to provide a theoretical framework for examining social media characteristics and their impacts on consumer perception. In addition, this study practically suggests that marketers and network managers need to use differentiated communication strategies for twitters as a marketing strategic option.

This study explores the influence of reference groups depending on the type (in-group versus out-group) and the size (an individual member versus a group as a whole) of reference groups. We propose a mixed conformity model, which suggests that people want to fit in with their in-group but at the same time they want to stand out within their in-group members. We found that in moderately identity-relevant product categories, people tend to diverge from individual members of their in-group while conforming to their in-group as a whole. However, in highly identity-relevant product categories, people conform to their in-group independent of the referent's size. Directions for future research are outlined in order to further establish and understand the proposed phenomenon.

In the summer of 2008, the movie Dachimawa Lee: Villain, Get on the Express to Hell is waiting for its first release. This movie is based on a short film which was tremendously popular when it was first introduced on the internet in 2000, and the director Ryu Seung Wahn is expecting a mega hit of the movie this summer. Showbox is one of the leading movie distributors in Korea. After a series of blockbuster hits such as Welcome to Dongmakgol, The Host, and The Chaser, Showbox is now in stagnation. Along with sluggish economy in Korea, most of recent movies distributed by them didn't even reach the breakeven. However, expectation on the upcoming movie, Dachimawa Lee, is higher than ever. Marketing department of Showbox has to decide what kind of media channel to choose and which marketing strategy to apply. It needs to make a decision about whether to target the so-called mania group or the general public of much bigger size. In this case study, the distinctiveness of the movie marketing and its process will be discussed. Moreover, the marketing strategies for Dachimawa Lee's success will be examined in the Showbox's point of view.

The changing of clothes in Balagtas' 1860 fictional comedy La filipina elegante y negrito amante (The Elegant Filipina and the Amorous Negrito) is used to explore the ethnic, cultural, and sartorial diversity in 19^th century colonial Philippines. But, how does plurality in men's clothing reflect the socio-economic conditions of the late Spanish colonial period? This paper focuses on the diversity in Philippine men's clothing around 1850 to 1896, taking into account the limited range of colonial archetypes in iconographic and documentary sources. Underscoring the colonial culture that shaped mentalities and tendencies, this study offers insights on how clothing was used and how it was perceived in relation to the wearer. In discussing clothing diversity, distinctiveness was articulated using the work of J.A.B. Wiselius (1875), a Dutch colonial administrator in neighboring Indonesia, who in comparing Spanish and Dutch systems of colonial governance, underscored the Filipino penchant for imitation.

In this paper, our primary focus revolves around the examination of a set of fractional stochastic models. Through our investigation, we can establish the presence of a solution and its distinctiveness. Additionally, we employ a moment-based algorithm to estimate the coefficients within these models and provide evidence that these estimations maintain their asymptotic characteristics. To support this claim, we conduct experimental studies using simulations and numerical examples.

이 연구는 한반도 지형이 가지고 있는 특수성과 일반성을 파악하여 국토 및 환경관리에 응용될 수 있는 지형관리원칙을 찾으려는 목적으로 이루어졌다. 동아시아를 대상으로 대륙규모와 국가규모, 그리고 지역규모 지형분석을 순차적으로 진행하였다. 동아시아는 복잡한 지구조적 특성을 보이지만, 대륙규모에서 뚜렷한 북동-남서 방향의 지형구조와 연결성이 나타난다. 한반도는 이러한 대륙규모의 지형특성을 따르면서도, 직각으로 교차하는 북북서-남남동 방향(낭림산맥과 태백산맥)의 지형연결성이 특징적으로 나타난다. 한반도는 국가적인 규모에서 동아시아에서 지형다양성이 가장 높은 곳 중의 하나로, 평균고도는 높지 않지만 인접한 지역에 비해 상대적으로 높은 경사도와 복잡한 지형다양성을 보인다. 한반도와 유사한 지형적 특성을 보이는 러시아의 시호테알린, 중국의 화남, 그리고 일본과 비교할 경우, 한반도는 산지와 퇴적평지의 경계가 자연스럽게 이어지는 반면, 다른 지역은 산지와 퇴적평지가 뚜렷하게 구분되는 특징을 보인다. 동아시아 지역규모에서 나타나는 지형의 특수성과 다양성에도 불구하고 산정상부에서 하천으로 이어지는 사면의 연결성은 모든 지역에서 동일하게 적용되는 지형의 일반적인 원칙이었다. 이러한 공간적인 연결성과 그와 관련된 각종 지형 및 생태현상들을 종합적으로 고려하는 것이 지속가능한 지형관리의 가장 핵심적인 요인이 될 것이다.
