  • The purpose of the study is to microscopically re-clarify the reality of renovation and conflicts that females faced within their families since the modernization period. The research method is the literature review. Families have been considered based on the formation of individual spaces for housing by husband and wife. The study will analyze changes in daily lives and housing consciousness to understand how such housing areas are transforming. The results of the study are as follows. From the perspective of symbolic interaction, in a traditional society, Korean females have been experiencing alienation and isolation in private areas in their daily lives due to family centrism and male chauvinism. Since industrialization, the female's role as the major consumer has been emphasized. Also, in terms of housing space, the symbol of family interaction was influenced more by utility, rationality, and equality than spatial hierarchy. From the perspective of the dailiness of phenomenological traditions, the modern girl's housing consciousness, which appeared during modernization under colonial rule, is considered as revolutionary from traditional society. Soon after in industrialized society, females appeared as leaders of 'sweet home'. They also became the main body to create the space for living by giving meaning to the interior of housing. Considering dailiness from the Marxist perspective, under the colonial social system, females became the subject of colonization through education, socialization, and the labor market. The modern public system presents the female as 'a wise mom and good wife' or laborer causing the colonization of her life. After industrialization, the socialization of housing and prioritization of spending caused the daily lives of females to become colonized by the consumption market.

  • In the offshore project such as semi-submersible FPU and FPSO, the free fall type life boat called TEMPSC (Totally Enclosed Motor Propelled Survival Craft) has been installed for the use of an emergency evacuation of POB (People on Board) from the topside platform. For the design of life boat arrangement for semi-submersible FPU in the initial design stage, the drop height and launch angle are required fulfill with the limitation of classification society rule and Company requirement, including type of approval as applicable when intact and damage condition of the platform. In this paper, we have been performed the numerical studies to find proper arrangement for the life boats consider drop height in various environmental conditions such as wave, wind and current. In the calculations, the contributions from static and low frequency (LF) motions are considered from the hydrodynamic and mooring analysis as well as damage angle from the intact and damage stability analysis. Also, Air-gap calculation at the life boat positions has been carried out to check the effect on the life boat arrangement. The air-gap assessment is based on the extreme air-gap method includes the effect of 1st order wave frequency (WF) motions, 2nd order low frequency roll/pitch motion, static trim/heel and set down.

  • Automatic on-line surface inspection systems have been applied for monitoring a quality of steel strip surfaces. One of the important issues in this application is the performance of on-line defect classifiers. Rule-based classification table methods which are conventionally used for this purpose have been suffered from their low performances. In this work, probabilistic neural networks and the enhanced classification tables which are newly proposed here are applied as alternative on-line classifiers to identify types of surface defects on cold rolled strips. Probabilistic neural networks have shown very excellent performance for classification of surface defects.

  • An overall responding security-centered framework is necessary required for infringement accidents, failures, and cyber threats. On the other hand, the correspondence structures of existing administrative, technical, physical security have weakness in a system responding to complex attacks because each step is performed independently. This study will recognize all internal and external users as a potentially threatening element. To perform connectivity analysis regarding an action, an intelligent convergence security framework and road map is suggested. A suggested convergence security framework was constructed to be independent of an automatic framework, such as the conventional single solution for the priority defense system of APT of the latest attack type, which makes continuous reputational attacks to achieve its goals. This study suggested the next generation convergence security framework to have preemptive responses, possibly against an APT attack, consisting of the following five hierarchical layers: domain security, domain connection, action visibility, action control, and convergence correspondence. In the domain, the connection layer suggests a security instruction and direction in the domains of administrative, physical and technical security. The domain security layer has consistency of status information among the security domain. A visibility layer of an intelligent attack action consists of data gathering, comparison and decision cycle. The action control layer is a layer that controls the visibility action. Finally, the convergence corresponding layer suggests a corresponding system of before and after an APT attack. The administrative security domain had a security design based on organization, rule, process, and paper information. The physical security domain is designed to separate into a control layer and facility according to the threats of the control impossible and control possible. Each domain action executes visible and control steps, and is designed to have flexibility regarding security environmental changes. In this study, the framework to address an APT attack and load map will be used as an infrastructure corresponding to the next generation security.

  • This study is a review of Ipsik, the decorative ornaments found on traditional Korean horsehair hats, known as Ipja, which were worn by men in the late Joseon Dynasty. In a broad sense, Ipsik are regarded as men's accessories. Therefore, although this study is limited to Ipja, it is significant in the sense that it delves into one facet of men's accessories in detail. Because the appearance of the horsehair hats was rather mundane, Ipsik and Ibyeong were added as ornaments. During the Joseon period, various types of hat ornaments existed, named Maeksu, Hosu, Gongjagu, Sangmo, Jingdori, Ijeon, Guyeongja and Ibyeong. A person's social ranking and class could be discerned by the materials used in the Ipsik he wore. Jeongja, a decorative accessory used to attach to an official's hat, was institutionalized in the sixteenth year of King Gongmin's reign(1367), during the Goryeo Dynasty, prior to the founding of China's Ming Dynasty in 1368, which indicates that Jeongja were influenced by the Yuan Dynasty. A record in Lao Chi'ta (a textbook of spoken Chinese estimated circa 1346) confirms this fact. Based on a review of literature, we learn that just as with Ongno, Jeongja were imported for use on Jeonrip, a soldier's hat. During the Ching Dynasty, Jeongja were further subdivided and more exquisitely designed. On the other hand, in the Joseon Dynasty, a rule was handed down mandating that a royal prince use gold for his jeongja, officials at third rank or above use silver, and governors, commanders in chief, and officials with the Office of Inspector General and Office of Censor General use jade. Inspectors were permitted to use crystal. Jeongja made of jade were used until the late Joseon Dynasty.

  • In the current code design, the use of a uniform internal pressure coefficient of cooling towers as internal suction cannot reflect the 3D characteristics of flow field inside the tower body with different ventilation rate of shutters. Moreover, extreme weather such as heavy rain also has a direct impact on aerodynamic force on the internal surface and changes the turbulence effect of pulsating wind. In this study, the world's tallest cooling tower under construction, which stands 210m, is taken as the research object. The algorithm for two-way coupling between wind and rain is adopted. Simulation of wind field and raindrops is performed iteratively using continuous phase and discrete phase models, respectively, under the general principles of computational fluid dynamics (CFD). Firstly, the rule of influence of 9 combinations of wind speed and rainfall intensity on the volume of wind-driven rain, additional action force of raindrops and equivalent internal pressure coefficient of the tower body is analyzed. The combination of wind velocity and rainfall intensity that is most unfavorable to the cooling tower in terms of distribution of internal pressure coefficient is identified. On this basis, the wind/rain loads, distribution of aerodynamic force and working mechanism of internal pressures of the cooling tower under the most unfavorable working condition are compared between the four ventilation rates of shutters (0%, 15%, 30% and 100%). The results show that the amount of raindrops captured by the internal surface of the tower decreases as the wind velocity increases, and increases along with the rainfall intensity and ventilation rate of the shutters. The maximum value of rain-induced pressure coefficient is 0.013. The research findings lay the basis for determining the precise values of internal surface loads of cooling tower under extreme weather conditions.

  • The way for seller to procure the goods for selling is to produce the goods at his own factory and to buy the manufactured goods from the other company. In order to produce the goods for selling the seller have to obtain the resource from the domestic company or overseas. In the middle of producing the goods to sell, seller may breach the right of a third party based on intellectual property rights. That is to say, seller may use the machine that has not itself been patented and use a process which has been patented by a third party. Seller may manufacture the goods which themselves are subject to the third party industrial property rights. Nowadays it is stressed the importance of intellectual property rights such as a patent, brand, and design. These factors consist of the core elements of the competitiveness of the goods. Many embedded software have been used in the various sector. So the disputes regarding to the intellectual property rights is gradually increasing in number. Article 42 of CISG defines the seller's delivery obligations and liabilities in respect to third party intellectual property rights and claims. It contains a special rule for this similar kind of defective in title, which tries to provide an proper solution to the complex problems caused by such rights and claims in international transactions. When seller will apply this clause to the business fields, there are several points to which seller should give attention. First, Intellectual property is general terms in intangible property rights, encompassing both copyright and industrial property. Which matter fall within the scope of intellectual property? The scope of intellectual property can be inferred from the relevant international conventions, which are based on broad international consensus. Second, Article 42 of CISG governs the relationship between the seller and the buyer, that is to say, questions of who has to bear the risk of third party intellectual property rights. The existence of such intellectual property rights, the remedies available and the question of acquiring goods free of an encumbrances in good faith are outside the scope of the CISG. The governing law regarding to the abovementioned matters is needed.

  • Research on AI is essential to build a system with collective intelligence that allows a large number of UAVs to maintain their flight while carrying out various missions. A typical approach of AI includes 'top-down' approach, which is a rule-based logic reasoning method including expert system, and 'bottom-up approach' in which overall behavior is determined through partial interaction between simple objects such as artificial neural network and Flocking Algorithm. In the same study as the existing Flocking Algorithm, individuals can not perform individual tasks. In addition, studies such as UAV formation flight can not flexibly cope with problems caused by partial flight defects. In this paper, we propose organic integration between top - down approach and bottom - up approach through multi - agent system, and suggest a flight flight algorithm which can perform flexible mission through it.
