This study aimed to analyze the consumption value and clothing pursuit benefits of genderless fashion based on gender identity. The study questionnaire was distributed to and collected from men and women in their 20s and 30s living in Seoul City and the Gyeonggi province. The collected data were analyzed by using Cronbachs α, factor analysis, K-means group classification analysis, and ANOVA. The study results were as follows. First, gender identity was categorized into three groups: the genderless group, the traditional gender rejection group, and the traditional gender acceptance group. Therefore, it is necessary to subdivide gender identity rather than acceptance and rejection of traditional gender roles. Second, an analysis of consumption value based on gender identity showed significant differences in terms of fashion value and expressive value. Therefore, it is important to establish a differentiated strategy based on the relevant gender identity group when establishing genderless fashion design or marketing strategy. Finally, the study results showed that clothing pursuit benefits based on gender identity, there was a significant difference in terms of individuality pursuit, deviation from the norm, and fashion pursuit. In particular, since the genderless phenomenon agrees with the characteristics of the MZ generation, it will be necessary to share brand information or product information through digital media or to utilize a sharing culture-that is, 'meaning out' tendency and 'flex culture' (i.e., conspicuous consumption).

Through the new round DDA(Doha Development Agenda) negotiations which started in Doha/Qatar conference in November, 2001, service industries have been included in the category of international trades. An electronic commerce cannot be exceptional in this field. The 21st century is largely recognized as the era of globalization, knowledge, and information. To make effective and competitive strategy in this century, it is essentially required to organize Network. OPEN, and FU-PLEX. That is why our government also has been promoting this field since years before, now 10,000,000 people in Korea have joined superhighway internet networks. Korea became the top internet-developed country in the world. As a side-effect of this internet spread into our life, however, there is serious problem we are now faced against. That is the outflow of private information through electronic commerce and other cyber transactions. It has caused many social problems to be rapidly on the rise these days. We are now desperately required to struggle continuously to make a solution for that. Taking the precedent case of Germany and United States which are currently recognized as high-leveled country in protection of private information, we have to come up with legal and technical measures and at the same time, to escalate the social consciousness about private information protection.

Objective : Endovascular treatment of large, wide-necked intracranial aneurysms by coil embolization is often complicated by low rates of complete occlusion and high rates of recurrence. A flow diverter device has been shown to be safe and effective for the treatment of not only large and giant unruptured aneurysms, but small and medium aneurysms. However, in Korea, its use has only recently been approved for aneurysms <10 mm. This study aims to compare the safety and efficacy of flow diversion and coil embolization for the treatment of unruptured aneurysms ≥7 mm. Methods : The participants will include patients aged between 19 and 75 years to be treated for unruptured cerebral aneurysms ≥7 mm for the first time or for recurrent aneurysms after initial endovascular coil embolization. Participants assigned to a flow diversion cohort will be treated using any of the following devices : Pipeline Flex Embolization Device with Shield Technology (Medtronic, Minneapolis, MN, USA), Surpass Evolve (Stryker Neurovascular, Fremont, CA, USA), and FRED or FRED Jr. (MicroVention, Tustin, CA, USA). Participants assigned to a coil embolization cohort will undergo traditional endovascular coiling. The primary endpoint will be complete occlusion confirmed by cerebral angiography at 12 months after treatment. Secondary safety outcomes will evaluate periprocedural and post-procedural complications for up to 12 months. Results : The trial will begin enrollment in 2022, and clinical data will be available after enrollment and follow-up. Conclusion : This article describes the aim and design of a multi-center, randomized, open-label trial to compare the safety and efficacy of flow diversion versus traditional endovascular treatment for unruptured cerebral aneurysms ≥7 mm.

Purpose : The aim of this study was to assess the efficacy and safety of recent-generation patent ductus arteriosus (PDA) closure devices applied by a new selection strategy according to the characteristics of each PDA. Methods : From February 2003 to January 2006, 138 patients underwent transcatheter closure of PDA (study group). According to the size and morphology of each ductus, a COOK Detachable Coil or 'flex' PFM Nit-Occlud was used for a small ductus (group 1, n=43); 'medium' PFM Nit-Occlud (group 2, n=49) for a moderate ductus; and an Amplatzer Duct Occluder (group 3, n=46) for a large ductus. The 83 patients who underwent transcatheter closure of PDA from February 2000 to January 2003 were defined as the comparison group. The Qp/Qs ratio, pulmonary/aorta pressure ratio, and MD of the ductus were compared. Immediate and follow-up results including residual shunts and complications were also evaluated and compared among groups. Results : In all 138 patients, complete occlusions were confirmed without major complications, while procedure failure (n=2, 2.2%), device embolization (n=1, 1.1%), and persistent residual shunt (n=4, 4.5%) were documented in the comparison group. Total complication rates were lower in the study group than in the comparison group (study group, 1.4%; comparison group, 9.0%; P<0.05). Conclusion : A novel strategy adopting the merits of various recent-generation devices for transcatheter closure of PDA provides excellent clinical results with minimal risk.

The aim of this study was to investigate the kinematics of young adults during ascent ramp climbing at different inclinations. Twenty-three subjects ascended a four step at four different inclinations(level, $8^{\circ},\;16^{\circ},\;24^{\circ}$). The 3-D kinematics was analysed by a camera-based falcon system. Groups difference was tested with one -way ANOVA and SNK test. The different kinematic patterns of ramp ascent were analysed and compared to level walking patterns. The kinematics of ramp walking could be clearly distinguished from the kinematics of level walking. In sagittal plane, Ankle joint was more dorsiflexed at initial contact and Max. dorsiflex. during stance phase with $16^{\circ},\;24^{\circ}$ inclination and more plantarflexed at toe off and Max. plantarflex. during swing phase with $24^{\circ}$(p<.001). Knee joint was more flexed at initial contact with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Hip joint was more flexed at initial contact and Max. flex. during swing phase with $16^{\circ},\;24^{\circ}$ inclination and at toe off with $24^{\circ}$(p<.001) and was more extended at Max. ext. during stance phase with $24^{\circ}$(p<.05). In frontal plane, ankle joint was more everted at Max. eversion. during stance phase with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Knee joint was more increased at Max. varus. during stance phase with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Hip joint was not differentiated with different inclinations. In horizontal plane, all joints were not differentiated with different inclinations. Conclusionally, In ascent ramp walking, the different gait pattern generally occurred at over $16^{\circ}$ on the ascending ramp in sagittal and frontal plane. These results suggest that there is a certain inclination angle or angular range where subjects do switch between a level walking and a ascent ramp walking gait pattern. This shows their motor control strategy between level and ascent ramp walking. Further studies are necessary to confirm and detect the ascent ramp gait patterns.
