Based on an analysis of the Japanese animation director Kamiyama Kenji's Ghost in the Shell: Stand Alone Complex series, this paper discusses two important subjects in modern technoscience-cyborg and old age. In fact, age has been an important social and political category in the modern world, along with gender, race, and class. However, age has not been a significant research topic for STS scholars. Even though many of these investigators have extensively explored the complex relationship between gender and technoscience, especially after the publication of Donna Haraway's "Cyborg Manifesto" (1991), few of them have been interested in how age is reconfigured by modern science and technology. If women, as Haraway has claimed, can have a different political and cultural outlook by becoming cyborgs, then, can we expect a similar socio-cultural transformation with regard to the interaction between cyborg and old age? Do the elderly experience lesser age discrimination through the growth of biomedicine and technoscience? Indeed, it is believed that seniors are increasingly becoming cyborgs with advancing age, since their declining bodily functions are consistently replaced and assisted by various biomedical technologies. Does this enable them to overcome ageism and age discrimination as well as their alleged physiological and mental limitations? As an answer to this question, Mike Featherstone has asserted that becoming a cyborg in old age could make the wrinkled skin a mere mask and create diverse new possibilities that were hitherto unavailable to an aging person. Based on my reading of Ghost in the Shell, however, I analyze a more complex set of problems when the senile cyborg is created through the encounter between the elderly and technoscience. I argue that while the senile cyborg could challenge traditional family ideology and nationalism it would leave ageism intact and define a new individualistic life form through a body controlled within the globalized internet and capitalist economy.

It has been only few years that various contents information subject for information processing system has been remarkably increased in online. If we say the year 2000 is the technology based year when deluge of information and data such as real time sharing, the time since after 2000 until 2011 has been a period plentiful of application based functions and solutions. Also, as the applicable range of these information process systems extends, individual information effluence has been social issues twice in 2009 and 2010. Thus now there are continuous efforts made to develop technologies to secure and protect information. However, the range problem has been extended from the illegal access from outside to the legal access from internal user and damages by agents hidden in internal information process system and client system. Therefore, this study discusses the necessity for the studies on efficiency based information security by control of access to internal information and authority setting for administrator and internal users. Based on the result of this study, it provides data that can be used from SOHO class network to large scale for information security method.

This study is a survey of collection development policies in the 40 university libraries among 42 in Korea as of 1984. The survey used a questionnaire with 36 questions concerning the basic elements of the collection development policy. The survey results revealed many problems demanding correction. The measures to correct the problems in the university libraries are as follows. 1. It is desirable that the libraries should have a collection development policy statement written and adopted for the systematic collection building. 2. It is advisable that the libraries should include a function of the materials selection among other various functions of the Library Committee for the purpose of informing administrators of the goals of the libraries and the validity of the budgetary allocation. 3. It is desirable that each library should organize the Collection Development Committee for minimizing the possibility of personal bias on the part of the individual selectors. 4. It is advisable that the primary responsibility for materials selection should be delegated as follows: for the materials for faculty research, to the faculty members; for the other collections, to the professional staff of each department; for the final review of whether or not to purchase, to the Collection Development Committee. 5. It is desirable for the purchase priority of materials to be set up in accordance with the order of 6 levels of collection development. 6. It is advisable that the libraries should, as top priority, purchase materials in direct su n.0, pport of the undergraduate and graduate academic programs, and in subject matter areas other than languages and literature, Korean materials should have not only the higher priority than the foreign language materials, but also maintain the comprehensive collection level. 7. It is desirable that the special collections should be purchased by special funds from the authority, and the special collections librarian should have the responsibility of the materials selection under the advice of the faculty members relating to the subject area. 8. It is advisable that duplicate copies should be bought only for high use items, but for reserve books, by the program enrollment, and textbooks should not be bought in general, except as su n.0, pplemental materials for course work in which they are necessary and heavily used. 9. It is reasonable that the material budget should be distributed as follows: by the ratio for distributing funds, about 60-70% for the library and 30-40% for departments; by the type of materials, about 50% for books, 40% for periodicals and 10% for other materials, or when not bought other materials, about 50-60% for books and 40-50% for periodicals. In addition, it is desirable that undergraduate class enrollment, graduate class enrollment, undergraduate majors, graduate majors, average book cost in the discipline, number of faculty, and use rate by subject should be considered as the factors for the allocation of funds by department, and special consideration should be given to newly-founded departments so the library holdings can be adequate to su n.0, pport them.

In this study, the twist angle and wing planform shapes were selected as design variables and optimized to secure the stability of the flying-wing type UAV. Flying-wing aircraft has no separated fuselage and tails, which has advantages in aerodynamic characteristics and stealth performance, but it is difficult to secure the flight stability. In this paper, the sweep back angle and twist angle were optimized to obtain the lateral stability, the static margin and wing planform shapes were optimized to improve the longitudinal stability of the flying-wing, then effect of the twist angle was confirmed by comparing the stability of the shape with the winglet and the shape with the twist angle. In the optimization formulation, focusing on improving stability, constraints were established, objective functions and design variables were set, then design variable sensitivity analysis was performed using the Sobol method. AVL was used for aerodynamic analysis and stability analysis, and SQP was used for optimization. The CFD analysis of the optimized shape and the simulation of the dynamic stability proved that the twist angle can be applied to the improvement of the lateral stability as well as the stealth performance in the flying-wing instead of the winglet.

We present a methodology to design energy-efficient data paths using FPGAs. Our methodology integrates domain specific modeling, coarse-grained performance evaluation, design space exploration, and low-level simulation to understand the tradeoffs between energy, latency, and area. The domain specific modeling technique defines a high-level model by identifying various components and parameters specific to a domain that affect the system-wide energy dissipation. A domain is a family of architectures and corresponding algorithms for a given application kernel. The high-level model also consists of functions for estimating energy, latency, and area that facilitate tradeoff analysis. Design space exploration(DSE) analyzes the design space defined by the domain and selects a set of designs. Low-level simulations are used for accurate performance estimation for the designs selected by the DSE and also for final design selection We illustrate our methodology using a family of architectures and algorithms for matrix multiplication. The designs identified by our methodology demonstrate tradeoffs among energy, latency, and area. We compare our designs with a vendor specified matrix multiplication kernel to demonstrate the effectiveness of our methodology. To illustrate the effectiveness of our methodology, we used average power density(E/AT), energy/(area x latency), as themetric for comparison. For various problem sizes, designs obtained using our methodology are on average $25\%$ superior with respect to the E/AT performance metric, compared with the state-of-the-art designs by Xilinx. We also discuss the implementation of our methodology using the MILAN framework.
An intelligent service robot is a robot that monitors its surroundings, and then provides a service to meet a user's goal. It is normally impossible for a robot to anticipate all the needs of its user and various situations in the surroundings ahead, and to prepare for all the necessary functions to cope with them. Therefore, it is required to support the self-growing capability by which robots can extend their functionality based on users' needs and external conditions. In this paper, as an enabler of the self-growing capability, we propose a method that allows a robot to select a component-composition pattern represented in an architectural form (called a sub-architecture), and to extend its functionality by obtaining a set of software components that are prescribed in the pattern. Sub-architecture is selected and instantiated not only based on the functionality required but also based on quality requirements of a user and the surrounding environment. To provide this method, we constructed a quality-attributes-in-use ontology and developed a brokering mechanism that matches quality requirements of users and surroundings against quality attributes of sub-architectures. The ontology provides the common vocabularies to represent quality requirements and attributes, and enables the semantically-based reasoning in matching and instantiating appropriate sub-architectures in supporting services to users. This ontology-based approach contributes to provide a great flexibility in extending robot functionality based on available software components, and to narrow the gap between users' Quality requirements and the Quality of the actual services provided by a robot.
As smart phones have been increasingly used to access information with bigger screens and higher resolution, smart phones have rapidly grown larger. Even Apple which had stuck to the 4-inch smart phone screen size, released 5.5-inch iPhone 6 plus. In this trend of smart phone enlargement, manufacturers have mostly incorporated one-handed modes to 5-inch or larger phones to keep the convenience of one-handed operation. But most of them provide just smaller screens and are rather complicated to set up after several menus to touch. In this study, this research examined one-handed functions of each smart phone manufacturer to understand problems in the one-handed smart-phone manipulation of web-browsing which is one of the frequent smart phone services. And by investigating smart phone users, this research found out requirements for one-handed web search operation. Based on this examination, the author of this research designed an efficient one-handed interface for mobile web-search without reducing the screen size. Then, to assess the possible usability improvement, the prototype was applied to a large 5.5-inch-screen smart phone to evaluate its performance through observation and surveys and find out manipulation satisfaction and further improvements.
PURPOSES : This study examines the performance changes of road networks according to the strength of a disaster, and proposes a method for estimating the quantitative resilience according to the road-network performance changes and damage scale. This study also selected high-influence road sections, according to disasters targeting the road network, and aimed to analyze their hazard resilience from the network aspect through a scenario analysis of the damage recovery after a disaster occurred. METHODS : The analysis was conducted targeting Sejong City in South Korea. The disaster situation was set up using the TransCAD and VISSIM traffic-simulation software. First, the study analyzed how road-network damage changed the user's travel pattern and travel time, and how it affected the complete network. Secondly, the functional aspects of the road networks were analyzed using quantitative resilience. Finally, based on the road-network performance change and resilience, priority-management road sections were selected. RESULTS : According to the analysis results, when a road section has relatively low connectivity and low traffic, its effect on the complete network is insignificant. Moreover, certain road sections with relatively high importance can suffer a performance loss from major damage, for e.g., sections where bridges, tunnels, or underground roads are located, roads where no bypasses exist or they exist far from the concerned road, including entrances and exits to suburban areas. Relatively important roads have the potential to significantly degrade the network performance when a disaster occurs. Because of the high risk of delays or isolation, they may lead to secondary damage. Thus, it is necessary to manage the roads to maintain their performance. CONCLUSIONS : As a baseline study to establish measures for traffic prevention, this study considered the performance of a road network, selected high-influence road sections within the road network, and analyzed the quantitative resilience of the road network according to scenarios. The road users' passage-pattern changes were analyzed through simulation analysis using the User Equilibrium model. Based on the analysis results, the resilience in each scenario was examined and compared. Sections where a road's performance loss had a significant influence on the network were targeted. The study results were judged to become basic research data for establishing response plans to restore the original functions and performance of the destroyed and damage road networks, and for selecting maintenance priorities.
Christian Metz, the precursor of cine-semiology, considered cinema as a language in the sense that it is a set of messages grounded in a given matter of expression, and a signifying practice characterized by specific codifications. According to Metz, film forms a structured network produced by the interweaving of cinematic codes, within which cinematic subcodes represent specific usages of the particular code. For Metz, cinematic language is a totality of cinematic codes and subcodes, and history of the cinema is the trace of the competition, incorporations and exclusions of the subcodes. He also suggested a filmic text is not just a list of codes in effect, but a process of constant displacement and deformation of codes. Following Metz' textual analysis methodology, I investigated the formal configuration of Hayao Miyazaki‘s animation, Spirited Away. It is interesting to trace the interweaving of cinematic codes in Spirited Away, i.e. codes of lighting, color, movement, and auteurism, across the animation. I focused on the first scene at the bridge to Yubaba's bathhouse, analyzing each cinematic code and its subcode applied. The first bridge scene is carefully constructed to stand out the confrontation of Chihiro (with Haku) and the bathhouse. The bathhouse is not just a building, it represents the powerful witch, Yubaba, yet to appear on the scene, and functions as an antipode to Chihiro. In each shot, every subcode within the codes of framing, direction, angle, color, lighting and movement is used to maximize the contrast between the dominant bathhouse and the feeble 10-year-old girl. In Spirited Away, the subcodes within each cinematic ode are constantly competing and displacing each other to augment the antithesis between the characters and develop the narrative. As Metz's argument that film constitutes a quasi-linguistic practice as a pluricodic medium, Spirited Away communicates with the spectators with the combination and displacement of these cinematic codes and subcodes.

This experiment was conducted to clarify the functions of supernodulating characters on seed yield determination through the comparison of agricultural traits of supernodulating soybean mutants, Sakukei4, SS2-2, and their parent cultivars, Enrei and Shinpaldalkong2. The plant dry weights of supernodulating mutants, Sakukei4 and SS2-2, were $52\%$ and $61\%$ of their wild type parents at full seed stage (R6). However, the relative growth rate (RGR) from the pod set stage (R3) to R6 of Sakukei4 was 0.022 g/g/day and that of SS2-2 was 0.016 g/g/day, which were higher than those of their parents. Nodule number and dry weight were increased in two supernodulating mutants by the R6 stage. The nitrogen concentrations of leaf, petiole and stem of Sakukei4 were higher than those of Enrei. SS2-2 showed higher nitrogen concentration in petiole than Shinpaldalkong2 had. The positive correlations were appeared between nodule dry weight, plant dry weight and pod number, in two supernodulating mutants during the period from R3 to R6 stage. Although all of the yield components and seed yield were lower in two supernodulating mutants than their parents at the stage of full maturity (R8), the harvest index was higher in supernodulating mutants. The increasing rates of pod number to stem dry weight in two supernodulating mutants showed the higher than those of two their parents at R8 stage. In conclusion, the relative growth rates during the early to the middle reproductive growth period were higher in supernodulating mutants than the wild types. This could be resulted in an increase in pod number. The increase of relative growth rate was the result of the successive supplement of nitrogen source from biological nitrogen fixation (BNF) of nodules during the middle reproductive growth period in supernodulating mutants.
