  • 독점금지법과 지적재산권 양자간에는 항상 긴장관계가 존재해 왔다. 이러한 근본적인 대립관계에도 불구하고, 양자는‘소비자 복지의 극대화’와‘창조적 활동과 공정한 경쟁의 촉진’이라는 공통된 경제적 목적을 공유하고 있다(WARD S. BOWMAN, JR.,PATENT & ANTITRUST LAW: A LEGAL & ECONOMIC APPRAISAL 1-14 (1973). 그럼 과연 독점금지법이 지적재산권자 의 권리행사를 제한할 수 있을까? 만약 그것이 가능하다면, 어떤 경우에 지적재산권의 행사가 금지되는 것인가? 이하에서는 최근의 ‘마이크로소프트(MS)의 끼워팔기(tying) 사건’과 특허권자에 의한 거래거절행위의 위법성 여부가 문제됐던 미국의‘코닥사건’을 살펴봄으로써 이러한 궁금증을 해결하고자 한다.

  • This paper proposes the linear induction motor with salient poles, transverse flux and the secondary aluminum conductor for a new type urban MAGLEV. Compared with the more usual kind of linear induction motor with longitudinal flux, TFLIM have flux paths tying transversely to the direction of motion. This shortens the magnetic circuit and produces the thrust, the attraction force and the lateral stabilization force simultaneously. Owing to these electrodynamic force, TFLIM will be usable to a new type urban MGLEV.

  • In contemporary art, soft materials are used in various forms and ways as a medium expressing contingency beyond a simple nature of materials. In the late 1960's, the appearance of soft sculpture as a refusal of the stereotyped 'Erection' characteristic of traditional sculpture served as an opportunity for more attention to soft materials. Fashion is the reflection of age, and the mirror of society, culture and arts. In other words, soft sculpture and fashion are artistic behaviors in the same context, which have neither been fixed nor erected. This study finds its significance in analyzing correlation between soft sculpture and fashion, and the importance of contingency as artistic expression means in this age when boundaries between genres are obscure, and artistic values are given to fashion. By doing so, it aims to present the direction toward which fashion should face in the future, establishing a new aesthetic consciousness with which more creative and various expressions are available in fashion as well. This study presented as its theoretical background the concept of soft sculpture affected by Marcel Duchamp among representative examples of the contingency that started to appear in art starting in the early 20th century. It also analyzed the soft sculpture appeared in 1960s and the expression methods and features of contingency appeared in fashion after late 1990s through a new approach of piling up, hanging up, and tying, three categories classified by Maurice $Fr{\acute{e}}churet$. Common features of the contingency expressed in soft sculpture and fashion were derived in the analysis, which are intensive effects of energy, values given to physical properties themselves, and esthetics of anti-form.

  • The purpose of this study is to investigate the influence of service quality factors and related ties on the repurchase intention of home shopping products and application home shopping through smart media using relation bonding according to the platform. In this study, it was confirmed that the relationship between home shopping and home shopping follows the process of establishing brand equity by mediating or partially mediating the influence relationship between specific service quality factor and repurchase intention. At this time, the mediating effect of the relationship tying is different according to the home shopping platform, but the relation of the TV + application group to the use of TV home shopping has no mediating effect. Also, according to users' usual media usage habits, service quality factors for home shopping have different influence relations on repurchase intention through relationship binding.

  • In ancient China, Su(綬) was the ornament of the full dress. It had originated from tying the jade or another thing before Jen(秦:Qin) dynasty and it tied the imperial jade seal and the chop from Han dynasty. Su of Han dynasty was different in the inscape, colour, length and density according to the grade. And the shape was the straight line. But these phenomena were changed after Han dynasty. This study showed how it changed. To studying used the comparison method of literature records, paintings and archeological relics. It mostly studied imperial Su. Su of Han dynasty of the high grade was formed by Yeok, the circle type jade and Su(Su moaned whole Su, at the same time moaned the part of Su, too). Afterward, Yeok was changed into Small Su[小綬] and Su was changed into Big Su(大綬). Originally the circle type jade was connecting Yeok to Su, but it was changed into tying Small Su only. Su of Han dynasty used the four kinds of colour, but from Su(隋: Sui) dynasty used the six kinds of colour. Originally Su was interlacing, but it was changed into the silk fabric from Song[宋] dynasty. According to using silk fabric's Su, it was likely to disappear the system distinguishing the grade by length. And it kept the method of interlacing the reticulation in the low part of silk fabric's Su. So, after using silk fabric's Su, the system of the density was not about the main body but about the reticulation. Su was been used woven with supplementary golden wefts, too. The circle type jade was chiseled the dragon and cloud from Geum[金:Jin] dynasty. These not the pattern of silk fabrics.

  • Background: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a "knot-ache". This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. Methods: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. Results: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. Conclusions: The knots of suture anchor maybe a possible etiology of the pain, which we termed a "knot-ache". Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, "knot-ache". Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

  • As the number of aged-housing has been rapidly increased, many kinds of defects and problems such as degeneration of housing environment, structural performance, and equipment performance have been appeared. The reconstruction as the way to improve the aged-housing has been used mostly because the legal process of the reconstruction is relatively easy. On the other hand, it has caused problems such as the lack of natural aggregate, the environmental damages owing to construction wastes, the loss of national resources, and the lack of the housing for rent nearby the reconstruction area. This problems limit active tying into the reconstruction business at present in the industrial and political perspective. In this context, it is required to revitalize the remodeling rather than the reconstruction. In order to reach this objective, this research aims at identifying the user-oriented performance for the housing industry and developing the new technologies. It is expected that the result of this research can contribute to more revitalize the remodeling as tying researches in terms of design, structure, equipment, and construction.
