Objective: The purpose of this study was to provide data on gait characteristics of K-pop professional dancers. Method: Participants were divided into four groups: male dancers (n=10, age: $28.2{\pm}3.4years$, height: $175{\pm}6cm$, weight: $68.9{\pm}5.6kg$), female dancers (n=10, age: $26.7{\pm}3.1years$, height: $162{\pm}4cm$, weight: $52.1{\pm}3.7kg$), non-dancer males (n=10, age: $25.2{\pm}2.6years$, height: $171{\pm}6cm$, weight: $66.4{\pm}5.3kg$), or non-dancer females (n=10, age: $26.2{\pm}3.0years$, height: $161{\pm}5cm$, weight: $56.4{\pm}6.7kg$). Twelve infrared cameras (Qualisys, Oqus 500, Sweden, 150 Hz.) were used to capture three-dimensional motion data. Gait motion data of professional dancers and ordinary persons were obtained. Results: K-pop dancers' dynamic stability during the female toe off event and the male heel contact event was better compared with that of ordinary persons in the front-rear direction. In addition, the results showed a significant difference in the margin of stability (MoS). However, the medial-lateral direction of both female and male dancers during heel contact and the toe off event was more stable compared with ordinary person, who exhibited an increased MoS than did the dancers. Conclusion: This study aimed to investigate the gait characteristics of K-pop professional dancers in comparison with ordinary persons using gait parameters and MoS. The stability of K-pop professional dancers' dynamic gait in the front-rear direction was better than that in the medial-lateral direction. Therefore, further studies in which the dance movements of K-pop dancers are sub-divided and analyzed will be necessary to reduce related injury.

Objectives: This study aims to discover how the spread of K-POP and the diversification of the Korean Wave affects Korea's national reputation. K-POP stars are diversifying their interactions with fandom by creating an online space to consume various products and services related to their stars and engage in fan activities. Because of this, this study aims to examine the relevance of K-POP to national reputation through a parasocial relationship with K-POP stars by fandom forming a community and utilizing media. Methods: An online survey was conducted in English using the Amazon survey company Mechanical Turk for BTS fans living in the United States. A total of 195 people's data, excluding incomplete responses, were used for the analysis. Results: It was found that BTS fans' social media participation activities themselves did not directly affect Korea's national reputation. But the mediating effect of BTS fans' parasocial relationship was found. That is, BTS fans' social media participation activities had a positive effect on their parasocial relationships with BTS which in turn had a positive effect on their national reputation. Conlusions: The use and participation of BTS fans in social media in Korea's national reputation has no significant effect on itself, but it has been found that it affects the national reputation through forming parasocial relationships. From the study results, the parasocial relationship of K-POP fans can be used as a strategic mechanism to enhance the national image and Korea's national reputation.

This thesis urges the change of the education system of popular music for globalization of K-POP in a longer point of view Korean popular music has developed not only musically but also sound quality itself. Moreover it became popular in a global scale in the name of K-POP. However, it is still limited to idol music, and numerous issues related to the lack of musical talent are emerging Even though the routine of birth and death of several idol groups and singers are still repeated. Recently, the skills of artists enhanced due to audition TV shows but still it's not enough. Under this situation, it is not appropriate to rely on audition TV shows and Entertainment Management companies for picking up talented artists. Therefore, like Classic or Traditional music, schools concentrated for popular music must be founded. If this become enabled, young students going to entertainment companies or to unqualified but expensive private institutes will disappear. Moreover, it can prevent students from lacking behind in their academic activity. In addition, a reformation should be done education colleges for raising popular music educators

This study intended to empirically verify the effect of message framing, cognitive need for closure, and type of fashion products on purchasing attitude of PB fashion products in discount stores. The design consisted of three-mixed design of 2(POP(Point of Purchase)message framing: benefit message vs. loss message) ${\times}2$(cognitive need for closure: high vs. low) ${\times}2$(PB fashion product type: utilitarian vs. hedonic). Survey of this study was conducted on 330 men and women in 20~50's in Seoul and Gyeong-gi, and a total of 287 data were analyzed. Data were analyzed with SPSS 18.0 program, and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First, it was identified that the framing type of POP message of discount store, cognitive need for closure, and PB fashion product type had significant effect on preference and purchase intention. Secondly, it was identified that consumers with both high and low cognitive need for closure had high preference level and purchase intention when they encountered the benefit message framing than the loss message framing. Thirdly, the benefit message framing was more effective than the loss message framing for hedonic PB fashion products in discount stores, but utilitarian PB fashion products did not get affected by the message framing. Fourthly, it was identified that groups with both high and low cognitive need for closure preferred hedonic PB fashion products. Lastly, it was verified that benefit message framing POP advertisement on a group with high cognitive need for closure was effective for Hedonic PB fashion products in discount stores, and utilitarian PB fashion products showed no difference in purchase intention according to the POP message framing type and cognitive need for closure.

To understand 'Moving up the charts' as a dynamic phenomenon in the K-pop entertainment industry, this study specifically analyzed the 'Moving up the charts' of 「Rollin'」 sung by 'Brave Girls'. First, the context and process related to 「Rollin'」 were described in detail, and the performance as a sound source and business were described. Subsequently, six factors were analyzed and presented as causes for 'Moving up the charts': 'Existence of specific possible triggers', 'Attractions of content itself', 'Inflow of new male fans', 'Turning weaknesses into strengths as idol', 'Psychological empathy with stories of real group' and 'Fast response and communication of agency'. Due to the influence of 'Moving up the charts', two changes were presented: 'Expansion of popularity and interest and expansion beyond songs' and 'Forming a consumer group with high purchasing power'. Through this, this study discussed the meaning, role, and possibility of 'Moving up the charts' in the K-pop entertainment industry. In the future, it will be necessary to recognize 'Moving up the charts' in the music market as a remarkable phenomenon, and to understand the importance of new idol consumer class as well as the use of related media such as YouTube.

The study examined a sentiment analysis based on Tweeter messages between contemporary pop musicians and classical music composers. Musicians of each genre were carefully selected for the sentiment analysis. Many opinion messages on Tweets that users have discussed were collected, and the messages were evaluated by using Naïve Bayes Classifier. The results demonstrated that users showed high positive sentiments for the two different genres. However, on average, the positive sentiment values for classical music composers are higher than for contemporary pop musicians. In addition, the rankings of the highest positive sentiments among contemporary pop musicians and classical music composers did not coincide with the popularity of the two different genres of musicians. This study will contribute to the study of future sentimental analysis between music and musicians.

K-Pop is powerful. Once considered to be at the periphery of global music scene, it is now reaching the whole world. Not surprisingly, the media, domestic and foreign, have scrambled to unlock the secrets of K-Pop's phenomenal growth. In doing so, they have not failed to highlight the underside of its success, such as cut-throat competition among idol-group members and the programmed member replacement by their agencies. One of the most notable characteristics in this process is called, in their business jargon, 'the graduation system'. This paper attempts to explicate this management practice unique to K-pop industry. To do so, this paper draws on Rene Girard's work on desires, particularly his notion of mimesis, violence and the scapegoat mechanism. Based on a documentary film, interactive online sites and a monograph that have chronicled how the K-pop girl group <9 Muses> have 'graduated' during their debut process, this paper applies, as its main analytical tool, the scapegoat mechanism and attempts to explore on its basis what 'the system' entails for the K-pop industry in general and the actors working within it in particular.

The variability in the phosphorus concentrations and the decomposition rates of organic phosphorus were measured in two rivers, the Youngsan River and the Sumjin River through four surveys in June, August and December of 2006 and February of 2007. Water samples were incubated for 20 days in a dark incubator and the change of forms of phosphorus (POP, DOP, DIP) were analyzed. By fitting the change to four types of models the decomposition rates of organic phosphorus were determined. The mean total organic phosphorus (TOP) decomposition rate coefficients in the Youngsan River and the Sumjin River were $0.036day^{-1}$ and $0.035day^{-1}$, respectively. In POP$\rightarrow$DIP model, the average decomposition rate coefficients in the Youngsan River and the Sumjin River were 0.049 and $0.035day^{-1}$, respectively. The average POP decomposition rate coefficients of POP$\rightarrow$DOP$\rightarrow$DIP model were $0.042day^{-1}$ and $0.038day^{-1}$ in the Youngsan River and Sumjin River respectively while the mean DOP decomposition rate coefficients were $0.255day^{-1}$ and $0.244day^{-1}$, respectively. In the Youngsan River, the mean POP$\rightarrow$DOP decomposition rate coefficient and POP$\rightarrow$DIP decomposition rate coefficient of POP$\rightarrow$DOP$\rightarrow$DIP, POP$\rightarrow$DIP model were $0.039day^{-1}$ and $0.007day^{-1}$, respectively. And in the Sumjin River, the above decomposition rate coefficients were $0.031day^{-1}$ and $0.004day^{-1}$, respectively. The decomposition rate coefficients measured in this study might be applicable for modeling of river water quality.

In the parts including a vehicle, standard and contents are different according to type of automobile. Although the parts are same, the quality and requirement all are different according to vehicle production version. Also the business is shared at each department in a production line. So if a part is changed, each team or the department must recognize information which is changed. But currently if the event can occur at like this each department, because of parts management through handwork, the unification of information is difficult. Therefore in this paper, we applied POP systems at the automobile part enterprise and constructed POP based the automobile part productive integrated management system. This system supported productive information from mechanical, equipment, worker, and products in real-time and data update also is processed automatically. When this system is introduced, work time and cost remarkably will be reduced.
