This paper examines how Japanese society produced and reproduced a distinctively gendered history and memories of the experience of WWII and colonialism in the postwar era. We argue that these gendered narratives, which were embedded in postwar debates about the Peace Constitution and comfort women, have engendered contradictions and made the historical conflicts with neighboring countries challenging to resolve. On the one hand, this deepens conflict, but on the other, it also generates stability in East Asia. After Japan's defeat in WWII, the American Occupation government created the Peace Constitution, which permanently "renounces war as a sovereign right of the nation and the threat or use of force as means of settling international disputes." The removal of the state's monopoly on violence - the symbol of masculinity - resulted in Japan's feminization. This feminization led to collective forgetting of prewar imperialism and militarism in postwar Japan. While collectively forgetting the wartime history of comfort women within these feminized narratives, the conservative movement to revise the Peace Constitution attempted to recover Japan's masculinity for a new, autonomous role in international politics, as uncertainty in East Asia increased. Ironically, however, this effort strengthened Japan's femininity because it involved forgetting Japan's masculine role in the past. This forgetting has undermined efforts to achieve masculine independence, thus reinforcing dependence on the United States. Recurrent debates about the Peace Constitution and comfort women have influenced how Japanese political elites and intellectual society have constructed distinctive social institutions, imagined foreign relations, and framed contemporary problems, as indicated in their gendered restructuring of history.

Since Chappelear developed a Fourier approximation method, considerable research efforts have been made. On the other hand, Fourier approximations are unsuitable for deep water waves. The purpose of this study is to provide a Fourier approximation suitable even for deep water waves and a numerical method to determine the Fourier coefficients and the wave properties. In addition, the convergence of the solution was tested in terms of its order. This paper presents a velocity potential satisfying the Laplace equation and the bottom boundary condition (BBC) with a truncated Fourier series. Two wave profiles were derived by applying the potential to the kinematic free surface boundary condition (KFSBC) and the dynamic free surface boundary condition (DFSBC). A set of nonlinear equations was represented to determine the Fourier coefficients, which were derived so that the two profiles are identical at specified phases. The set of equations was solved using Newton's method. This study proved that there is a limit to the series order, i.e., the maximum series order is N=12, and that there is a height limitation of this method which is slightly lower than the Michell theory. The reason why the other Fourier approximations are not suitable for deep water waves is discussed.

A sketch is an intuitive means to express information, but compared to actual images, it has the problem of being highly abstract, diverse, and sparse. Recent advances in deep learning models have made it possible to discover features that are common to images and sketches. In this paper, we summarize recent trends in sketch-based image retrieval (SBIR) but it is not limited to SBIR. Besides SBIR, we also introduce sketch-based image recognition and generation studies. Zero-shot learning enables models to recognize categories not encountered during training. Zero-shot SBIR methods are also discussed. Commonly used free-hand sketch datasets are summarized and retrieval performance based on these datasets is reported.

From the economic point of view the fishing port is the complex of installations on land, organized to serve the fishing fleet and its cargo, and is the main link in the production chain of all components of the fishing industry, with the aim of achieving the planned targets with the minimum cost. Fishing port investment decisions have had significant impact on the development aims of Korean fisheries. Fishing port investments in Korea are made mostly by public or semipublic port authorities. Such investments should be judged not purely on the basis of financial profitability but rather on the extent to which they serve the development aims of the fishing industry. This makes the economic appraisal process more complex and presents certain problems in correctly quantifying the economic costs and benefits of the fishing port projects. This study concentrates more on the theoretical economic appraisal models than on the purely financial aspects of fishing port investments and points out the difference between the two approaches. In the result, there is clearly an element of judgment as to whether or not a shadow price needs to be used in estimating economic benefits and costs. From this viewpoint, some attempts are made to provide definitions of the possible economic benefits and costs, and methods for estimating and evaluating them in Part III and IV. Especially queueing theory is applied in the calculation of economic benefits. When a project is contemplated and analysis shows it to Lave a positive NPV, one question that arises is whether it should be implemented now or delayed. In this paper, the first year rate of return method is regarded as a more concise way of solving the timing of investment, At the end of Part IV, risk analysis of fishing port investments is considered. It can be handled in a number of ways, ranging from informal judgment to complex statistical analyses involving large-scale computer models, This paper recommends that evaluators of fishing port investments use the sensitivity analysis indicating exactly how much NPV will change in response to a given change in an input variable, other things held constant. Decisions regarding the amount of capacity to provide must be made in fishing port investments. Providing too much service would involve excessive capital costs. On the other hand, not providing enough service capacity would cause the waiting line of fishing vessels to become excessively long at times. Therefore, in Part V, the optimal number of berths and berth productivity in fishing port are defined as follows: Minimize E(TC) ＝ E(WC)＋E(SC) The minimum of this function is the solution and that is the optimal number of berth and berth productivity in fishing port.

In this paper, we propose a new design method of Genetic Algorithm Processor(GAP) and Evolvable Hardware(EHW). All sorts of creature evolve its structure or shape in order to adapt itself to environments. Evolutionary Computation based on the process of natural selection not only searches the quasi-optimal solution through the evolution process, but also changes the structure to get best results. On the other hand, Genetic Algorithm(GA) is good fur finding solutions of complex optimization problems. However, it has a major drawback, which is its slow execution speed when is implemented in software of a conventional computer. Parallel processing has been one approach to overcome the speed problem of GA. In a point of view of GA, long bit string length caused the system of GA to spend much time that clear up the problem. Evolvable Hardware refers to the automation of electronic circuit design through artificial evolution, and is currently increased with the interested topic in a research domain and an engineering methodology. The studies of EHW generally use the XC6200 of Xilinx. The structure of XC6200 can configure with gate unit. Each unit has connected up, down, right and left cell. But the products can't use because had sterilized. So this paper uses Vertex-E (XCV2000E). The cell of FPGA is made up of Configuration Logic Block (CLB) and can't reconfigure with gate unit. This paper uses Vertex-E is composed of the component as cell of XC6200 cell in VertexE

This paper deals with the annulment of the ICSID(International Centre for Settlement of Investment Disputes) arbitral award. The annulment of the ICSID is characterized by the fact that it can be made possible through the special committee of ICSID only. The annulment of the ICSID was constructed on the premise that it is not an appeal procedure. However in the initial period, it was strongly criticized as it allowed new trials or duplicated many of the functions of an appeal and it broke down the boundary between the two systems. Although the trend seemed to be corrected through its 2nd and 3rd generations, it was still criticized for functioning as a new trial. It is approaching its 4th generation. On the other hand, with the activation of investment agreement arbitration based on ICSID and FTA, a certain degree of consistency is required for the ICSID arbitralaward. Also, with the emphasis on the public features of the arbitration for the investment agreement, the necessity of an appeal system is presented. The ICSID Secretariat published the "Opinion on the Appeal Procedure" in 2004 but as the system was criticized as too early due to the cost allocation problem and others, its adoption of an appeal procedure has been delayed. This paper focuses on how the currently incomplete ICSID arbitration judgment annulment system shall be used. Although it is still hardto expect the quality and consistent arbitral award annulment in the ICSID, this paper suggests that the "annulment without the actual new trial" using the restricted authority of a special commission in a creative way shall be pursued rather than just the actual new trial with or without annulment, thus going back to the original concept of the ICSID arbitral award annulment.

The purpose of this study is to attempt to diversify artistic expression through combinations of the twelve zodiac animals and origami techniques and to propose new directions for fashion design by applying these to fashion accessory bag designs. For the research method, this study researched the representative forms and characteristics of twelve zodiac animals based on the cultural background. Also, diverse cases of origami techniques were sought to apply them to the development of bags. The results are as follows. First, expressed forms of the Chinese zodiac were newly expanded by realizing the form of Chinese zodiac animals through various origami techniques. Origami work displays abstract visual effects rather than intuitive feelings or expressions of flat designs. With this, detailed realizations could be made through the characteristics and cultural implications of animals. Second, the work created in this study utilized zero-waste patterns that use origami techniques on one whole piece. During pattern production, folded parts were marked without waste and the outer fabric and lining were produced. Patterns were all symmetrical lines so most forms were expressed with squares and equilateral triangles. Third, through actual work produced using fabric instead of paper, effects that are brought about through folding are determined in diverse ways according to fabric textures or material types and thicknesses. When paper is folded, shapes are created as folded, but fabric requires the use of supportive material to create the effects of origami. Polyester and blended fabric were easy to use with high levels of function and practicality. Through such diverse production attempts, fixing methods, hand sewing, sewing machines, double-sided tape, and leather adhesive were used.

In this paper, we proposed a face recognition network which attempts to use more facial features awhile using smaller number of training sets. When combining the neural network together for face recognition, we want to use networks that use different part of the facial features. However, the network training chooses randomly where these facial features are obtained. Other hand, the judgment basis of the network model can be expressed as a saliency map through gradCAM. Therefore, in this paper, we use gradCAM to visualize where the trained face recognition model has made a observations and recognition judgments. Thus, the network combination can be constructed based on the different facial features used. Using this approach, we trained a network for small face recognition problem. In an simple toy face recognition example, the recognition network used in this paper improves the accuracy by 1.79% and reduces the equal error rate (EER) by 0.01788 compared to the conventional approach.

GPS (Global Positioning System) made by the Department of Defense in U.S.A is positioning system to use satellite and initially it has been used only for the military forces but open to civilian in about 1987. This system has widely been used for not only surveying land, but also car navigation on the street and means to build up the data of the GIS. With GPS, recently our country is accelerating to make imbeded system and also the study on imbeded system is well under way. For example, Car navigation and the construction of the Seokang bridge between Willson Arch at Han river by using DGPS were evaluated as successful model to lead accurate location with the precision of the cm. The examples of the project performance with GPS has gradually been extended to the each department organization of the local and central government. for the example, It is true that BIS(Bus Information System) is widely spreading out. In addition, the study on the Distribution Maintenance System is expected to be well in progress to take advantage of GPS based on the data base of the NGIS(National Geography Institute System) of the NGI(National Geography Institute). This paper shows that we embodied not only the large imbeded system for car and finding the location in Korean Land Corporation but also the protype of the kinematics Wrist Held which is easily portable to pedestrian, climber and marathon runner.

Recently, unmanned terminals (kiosks) have greatly increased their scope of use by allowing orders or payments to be made efficiently while replacing existing manpower. With the acceleration of digital transformation, the rate of kiosk installations has soared, making it an important task to help all age groups easily use kiosks. In this study, based on the function of the game engine and Hand Tracking technology, we developed content that can conduct kiosk education in a virtual world. The goal of this content is to help users unfamiliar with kiosks confidently cope with real-world situations by experiencing visual and auditory stress caused by waiting guests in virtual reality. To this end, two VR contents were developed. One is a simple kiosk experience content, and the other is specialized content that causes visual and auditory stress. The experiment was divided into two groups: one group experienced general VR content, while the other group experienced specialized VR content. After the experience, both groups proceeded to place orders in an actual store. Survey results showed that 85% of the experimental group and 95% of the control group were satisfied with the training. This confirms that the specialized experience described in this paper is effective for kiosk education.
