Many types of meniscal anomalies have been reported. The authors encountered one case of anomalous insertion of the anterior horn of the medial meniscus to the anterior horn of the lateral meniscus, which ran up along the course of the transverse ligament. This anomalous band was detected in MRI of the knee as a horizontal tear of anterior horn of the lateral meniscus but found during the operation as a anomalous insertion of the anterior horn of the medial meniscus. We report the case with a review of the literature.

Students have a hard time with a formal proof, which is one of most important part in mathematics education. They were taught the proof with algebraic visual materials using technology and specialized visual materials. But, they experienced the difficulty in justifying due to the lack of experimental recognition with the representation using technology. The specialized visual materials limited the extension of mathematics thinking of students because it worked only for the case that is fixed. In order to solve this type of problem, we made algebraic visual materials for 9th graders using technology and generalized visual materials so that students experience for themselves to help them to experience experimental justification, thus we recognized that they were improved in enhancing mathematical thinking.

Advances in IT technologies are developing VR content technologies that provide five senses information to users and interact with them. These VR content technologies are widely used by users not only for time and space limitations but also for providing immersion experiences. VR contents are contents that allow users to experience images that are played on the screen through five senses such as augmented reality, virtual reality, and holograms as well as visuals. VR games are also becoming more diverse in interfaces for the interaction of users with VR games. This study recognized the importance of the interface and analyzed the impact of the application characteristics of VR game UI on user experience and satisfaction from the user perspective. Research shows that VR game UI interacts with user experience and satisfaction. This appears to affect user experience based on how well people using VR game UI can understand and utilize the characteristics and functions of UI.

The purpose of this study is to examine the effects of negative experiences on social capital in order to see if the adverse functions of social media could be a barrier to the promotion of social capital through the use of social media. The study verified the moderating effect of perceived performance from social media and negative experiences(victim experience and offender experience) on social capital. The online survey was conducted in November 2019, and a total of 846 responses were used for the final analysis. As a result of the two-step regression analysis using the mean-centering technique first, it was found that the victim experience had no significant effect on the bridge social capital, but the perceived performance and the victim experience had negative moderating effect on the bridge social capital. Second, the victim experience showed a significant positive effect on the binding social capital, but showed a negative moderating effect with the perceived performance indicating positive influence on the binding social capital of the perceived performance could reduce through victim experience. Accordingly it is necessary to educate social media users on the cyber ethics, and regulation is required to mitigate risk factors for trust.

In this study, there is a purpose of research to secure competitiveness through the effective utilization of intangible corporate resources of founded enterprises. For this research, we conducted a survey on the way the customers who used the products of the BI center and founders less than 7 years evaluated the founded company. Schmitt's empirical element was examined as a theoretical background, and it was examined whether these empirical factors and attitudes acted as a preprocess in the decision-making process as a repurchase intention. The Result of research is as follows. First, It clearly indicated that customer experience and search experience affected the degree of re-purchase. Second, customer's experience (use experience, search experience, contact experience) were grasped with significant influence on customer's attitude. Third, we discovered that customer's attitude had mediated between customer's experience (use experience, search experience) and re-purchase. This research suggests that if we manage empirical factors well, we can increase the degree of re-purchase and cope appropriately with the limitations of small and medium enterprises.

This study was to investigate which predictors influenced the wish to undergo cosmetic surgery according to experience of cosmetic surgery in female college students. A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 254 subjects. Data was analyzed with t-test and regression. There were statistically significant differences in acceptance and social motivation of cosmetic surgery and the wish to undergo cosmetic surgery in the future between the two groups. Body area satisfaction and acceptance of cosmetic surgery were significant predictors to the wish to undergo cosmetic surgery in the non-experienced group. The significant predictor of the wish to undergo cosmetic surgery for the experienced group was acceptance of cosmetic surgery. The findings from this study suggest that there is need to different approaches to discuss or council for wish to undergo cosmetic surgery according to individual cosmetic surgery experience.

최근의 현대 건축에서는 재료의 물성과 구축성이 두드러지는 프로젝트를 많이 발견할 수 있다. 이러한 경향의 배경에는 사양한 요인들이 있을 수 있다. 그 중에서도 공간성(性)에 대한 근본적이고 회귀가 중요한 바탕이라고 할 수 있다. 피터 줌터의 건축은 현란한 조형적 효과, 표현만을 위한 기술적 장식을 사용하지 않는다. 대신 그의 건축은 장소와의 관계, 문화적 context 상에서의 맥락, 그리고 공간의 근원적인 경험을 주요한 매체로 사용한다. 그리고 이러한 특수성은 대체적으로 빛과 재료의 고유한 적용으로 나타난다. 이는 장소와 문화의 특성을 관습적인 형태나 화려한 표현으로 재현하는 것이 아니라 '공간감'의 구현으로 구축하는 방식이다. 본 논문은 피터 줌터의 건축에 나타나는 빛과 재료의 구축 방식, 그리고 공간의 경험에 대하여 살펴본다. 그의 건축 구축 방식은 일견 간단해 보일 수도 있으나 실제로는 프로젝트마다 고유한 빛과 재료의 적용과 텍토닉(tectonic)이 내재되어 있다. 본 연구의 목적은 이러한 점들을 자세히 살펴보고 그러한 구축방식이 궁극적으로 어떻게 공간의 경험과 관계를 하는지 고찰하는 것에 있다. 구체적인 사례는 Bruder Klaus Chapel과 Kolumba Museum으로 한정된다. 프로그램은 다르지만 빛을 사용하여 관람자의 공간경험과 공간인지가 어떻게 형성되는지를 다루면서 결론 맺는다.

현대 그래픽스 장치의 발전은 수년전까지 Pre-Rendered 방식을 사용해서 볼 수 있었던 영상들을 Real-Time Rendering을 통해 실시간으로 인터렉티브하게 제공하고 있다. 이러한 장치의 발전은 게임, 시뮬레이션, 미디어 아트 등의 많은 분야에서 변화를 불러 일으켰으며, 앞으로도 많은 변화를 촉진시킬 것이다. 이러한 변화 중 하나로 기존까지 실시간으로 영상을 생성하기 힘들었던 분야 중의 하나인 미술 기법들의 실시간 재생이 가능해졌다. 본 논문은 미술 기법 중 판화기법과 탁본기법을 가상의 환경에서 모사할 수 있는 어플리케이션인 Virtual Engraving과 Virtual Frottage를 제안한다. Virtual Engraving은 3차원 공간상의 가상의 물체에 대해 3차원 입출력장치와 Bump Mapping을 이용하여 조각행위에 대한 경험을 사용자에게 제공하며, Virtual Frottage는 탁본의 대상을 영상으로 받아들여 영상 처리 기법과 Pixel Shader를 통한 렌더링을 통하여 사용자에게 흥미로운 프로타주 기법의 경험을 제공한다. 두 어플리케이션 모두 시각적인 정보를 통해 사용자에게 미술 기법의 경험을 제공하며, Virtual Engraving의 경우 3차원 입출력장치를 통해 촉각적인 정보를 제공하였고 Virtual Frottage 역시 촉각 피드백을 제공할 수 있도록 연구 중이다. 이러한 미술 기법의 모사 연구는 사용자에게 보다 더 실감적인 경험뿐만 아니라 실 공간에서는 가능하지 않은 여러 효과를 제공할 수 있다.

Seeking and recognizing maritime targets are very important tasks for maritime safety. While searching for maritime targets using radar is possible, recognition is conducted without automatic identification system, radio communicator or visibility. If this recognition is not feasible, radar operator must tediously recognize maritime targets using movement features on radar base on know-how and experience. In this paper, to support the radar operator's mission of continuous observation, we propose an algorithm for automatic recognition of an unknown ship using movement features on radar and a method of detecting potential ship related accidents. We extract features from contact range, course and speed of four types of vessels and evaluate the recognition accuracy using SVM and suggest a method of detecting potential ship related accidents through the algorithm. Experimentally, the resulting recognition accuracy is found to be more than 90% and presents the possibility of detecting potential ship related accidents through the algorithm using information of MV Sewol. This method is an effective way to support operator's know-how and experience in various circumstances and assist in detecting potential ship related accidents.
