정서현(Seo-Hyun Jung),박주연(Joo-Yeun Park) 한국정보사회학회 2021 정보사회와 미디어 Vol.22 No.3
본 연구는 이용자 충족자원을 기반으로 한 적소이론을 적용하여 영화 관람 매체 간 경쟁관계를 분석하였다. 연구대상 매체는 영화관, 유료방송 VOD, 그리고 OTT이다. 구체적인 연구문제는 세 개 매체에 공통적인 이용자 충족자원을 도출하고, 충족자원을 기반으로 세 개 매체에 대한 족소폭, 적소중복, 경쟁 우위를 살펴보고자 하였다. 세 매채를 모두 이용해본 경험이 있는 일반 성인을 대상으로 설문조사를 진행하였다. 연구결과는 다음과 같다. 첫째, 세 매체의 이용자 충족자원은 최신성, 다양성, 환경적 감흥성, 경제성, 용이성, 사회성 요인으로 나타났다. 둘째, 여섯 가지 요인에 대한 세 매체의 적소폭은 전반적으로 높고 균등하게 나타나 여섯 가지 충족자원을 고루 활용하는 것으로 나타났다. 미디어 환경이 변하더라도 여러 자원의 활용을 통해 적응할 수 있는 일반형 매체임을 의미한다. 셋째, 매체 간 경쟁구조에서는 충족자원에 따라 대체적 조건이 존재하거나 대체적 관계가 나타나는 경우, 그리고 독립적 공존 관계를 이루고 있는 구조가 나타났다. 구체적으로 OTT가 모든 충족자원에 대해 유료방송 VOD를 대체할 수 있는 조건이 존재하는 관계를 보였으며, 환경적 감흥성 차원에 대해서는 영화관과 OTT가 공존하고 있는 것으로 나타났다. 또한, 경제성, 다양성, 용이성 차원은 영화관보다 OTT가 우위를 점하며 대체적 관계를 보였다. 결과를 종합하여, 전반적으로 영화 관람 매체들은 치열한 경쟁상황에 있기보다 대체의 가능성이 높은 환경임을 확인할 수 있다. 이 연구는 영화 관람 매체가 다양해지고 있는 가운데, 현시점의 매체 간 경쟁구조를 파악함에 의의가 있다. This study tried to analyze the competitive relationship between film windows by applying niche theory based on user gratification resources. The film windows are movie theaters, VOD in Pay-TV, and OTT services. Specifically, research question 1 is to derive common user-gratification resources of the three film windows. Research Question 2 is to analyze niche breadth of each window and examine niche overlap and competitive superiority between windows. An online survey was conducted on ordinary adults who have watched movies in movie theaters, pay-TV VOD, and OTT services. The analysis was conducted based on a total of 309 responses. The research results are as follows. First, six common user gratification resources were derived at the three film windows. Specifically, the factors of recency, diversity, environmental sensitivity, price(affordability), perceived ease of use, and sociality were derived Each of these factors can be interpreted as a gratification resource at the content level(recency, diversity), environmental level(environmental sensitivity, perceived ease of use), economic level(price), and motivational level(sociality). Second, niche breadth of the three windows for the six factors was generally high and equal. All three film windows used resources evenly rather than relying on specific resources. So they were classified into generalist media. This means that even if the media environment changes, they are general media than can be adapted through the use of various resources. In the relationship between movie windows, niche overlap of social resources was high. Third, it was found that movie theaters had a relatively low similarity in resource utilization with the other two windows. However, in terms of price(affordability) resource, the level of competition between movie theaters and pay-TV VOD was high. In terms of sociality, it was found that the level of competition was high in all media competition relationships. The high level of competition at the sociality suggests that all three media provide and play a role in social exchanges with others at the stage of use and after use. In particular, OTT service is classified as a personalized service compared to the other two media, but social viewing functions such as Netflix Party and Watcha Party provided by OTT may have affected it. Fourth, in the competition structure between film windows, there was no relationship in a fierce competition Specifically, it was found that for all gratification resources, OTT service has a relationship in which conditions exist to replace pay-TV VOD. Therefore, regarding movie consumption there is a possibility that OTT service will replace pay-TV VOD. Movie theaters have been studied as the dominant window for movie consumption, but this study found that OTT services are superior to movie theaters in terms of price(affordability), diversity, and perceived ease of use. If OTT services emphasize strategies such as simultaneous release of theaters, there is a possibility that the level of utilization of recency resources in movie theaters will decrease. In addition, it was found that movie theaters and OTT services coexist in terms of environmental sensitivity. This is because the environment provided by the two windows is different. Movie theaters, such as dark spaces and large screens, provide the traditional sensitivity when watching movies. On the other hand, OTT service is characterized by being able to watch movies through various screens suitable for the user’s environment. When watching a movie through OTT service, people can choose a place to watch the movie and adjust the brightness. That is, the OTT service is a window that provides an active form of sensitivity capable of setting a user environment. For this reason, it is interpreted that the two windows coexist in terms of environmental sensitivity. This study is meaningful in that it has grasped the competitive structure among film windows at this poi

본 연구는 필라테스 동작 시 폼롤러의 적용과 움직임에 따른 몸통과 하지의 근활성도 차이를 알아보는 것이 목적이다. 피험자로 남자 8명을 선정하여 필라테스 네발자세, 교각자세, 코어컨트롤 동작을 매트위에서 정적동작, 폼롤러 위에서 정적동작, 폼롤러 위에서 동적동작으로 무선배정하여 1주 간격으로 수행하였다. 각 동작의 수행 시 척추세움근, 배곧은근, 배바깥빗근, 중간볼기근, 넙다리두갈래 근과 넙다리곧은근의 근활성도를 측정하여 일원분산분석으로 분석하였다. 유의수준은 α=.05로 설정하였 다. 첫째, 네발기기 동작에서 폼롤러 동적동작에서는 배곧은근, 배바깥빗근, 중간볼기근, 넙다리두갈래근의 근활성도가 높게 나타났으며(p<.001)(p<.05), 폼롤러 정적동작에서는 넙다리곧은근의 근활성도가 높게 나타났다(p<.001). 둘째, 교각자세 동작에서 폼롤러 동적동작에서는 넙다리두갈래근의 근활성도가 높게 나타났다(p<.001). 셋째, 코어컨트롤 동작에서 폼롤러 동적 동작에서는 배곧은근, 척추세움근, 중간볼 기근의 근활성도가 높게 나타났으며(p<.001)(p<.01), 정적 동작에서는 배바깥빗근의 근활성도가 높게 나타났다(p<.05). 필라테스 운동시 근활성도를 고려하여 방법과 난이도를 적용하면 더욱더 효과적일 것이라 사료된다. The purpose of this study is to investigate the difference of muscle activity according to application of a foam roller during pilates. The 8 male subjects were selected and quadruped position, bridge, and core control movement of pilates were randomly assigned to 9 movements on a static mat motion, static foam-roller motion, and dynamic foam-roller actions. This program was conducted once at intervals of 1 week. The muscle activity of erector spinae, rectus abdominis, external oblique, gluteus medius, rectus femoris, and biceps femoris were measured and the collected data was analyzed by one-way ANOVA. First, in the quadruped, the rectus abdominis and external oblique, rectus femoris of the dynamic foam-roller actions showed higher muscle activity than the static mat motion and the static foam-roller motion(p <.001), gluteus medius muscle activity was also significantly higher (p <.05). biceps femoris were significantly higher in static foam-roller motions than in static mat-motion and dynamic foam-roller actions(p <.05). Second, biceps femoris muscle activity was highest in dynamic foam-roller actions than static mat-motion and static foam-roller motions during bridge(p <.001). Third, in the sitting core control, the rectus abdominis and gluteus medius of the dynamic foam-roller actions showed higher muscle activity than the static mat motion and the static foam-roller motion(p <.001). and activity of erector spinae muscle was also significantly higher (p <.01). external oblique were significantly higher in static mat-motion than in static foam-roller motions and dynamic foam-roller actions(p <.05). Considering the muscle activity during pilates exercise, it would be more effective to apply the method and difficulty.
Open IPTV 환경에서 재암호화 과정 없는 댁내 컨텐츠 분배를 위한 키관리 기법
정서현(Seo-Hyun Jung),노효선(Hyo-Sun Roh),이현우(Hyun-Woo Lee),이정현(Jeong-Hyun Yi),정수환(Sou-Hwan Jung) 한국컴퓨터정보학회 2010 한국컴퓨터정보학회논문지 Vol.15 No.7
Due to the advancement of IPTV technologies, open IPTV services are a step closer to becoming reality. In such service environment, users are able to enjoy IPTV services using a variety of devices available at their home domain. However, it is impossible to get such flexible services at their convenience unless each of devices is individually connected to Set-Top-Box (STB) because of Conditional Access System (CAS) or service providers otherwise allow STB to freely distribute decoded contents to every user devices attached to STB. In this paper, we propose a key management scheme for securely distributing contents from STB to multiple user devices at home domain. The proposed scheme also makes the service providers be able to control the access rights to each of user devices without installing individual STBs. It is achieved by computationally dividing a private key of RSA signature scheme into three parts and thus makes possible to distribute the contents scrambled through a underlying CAS mechanism without re-encrypting them that the existing scheme should employ. It improves significantly computation and communication complexities, maintaining it as secure as the existing schemes. Additionally, it prevents misbehaving users from illegally distributing the contents from STB to their devices available at home domain.

Root resorption of the permanent maxillary incisors can occur due to ectopic eruption of the permanent canines. Severe root resorption threatens the long-term survival of the affected incisors. The aim of the present study was to identify risk factors for root resorption of the maxillary incisors associated with impacted maxillary canines. In the present study, we retrospectively analyzed the Cone-Beam Computed Tomography (CBCT) scans of 65 children and adolescents with ectopically erupting maxillary canines (total of 88 impacted canines). Root resorption of central incisors was significantly associated with the mesiodistal position and root development of the adjacent canine. Root resorption of lateral incisors was significantly associated with sex, age, and the buccolingual and vertical position of the adjacent canine. However, enlargement of the dental follicle was not significantly associated with root resorption of adjacent incisors. Although incisor resorption is difficult to diagnose and predict, our findings suggest that changes in the dental follicles of the erupting maxillary canines do not cause resorption of the adjacent permanent incisors. CBCT should be utilized to ensure early diagnosis of impacted canines and precise evaluation of incisor root resorption.
