History of architecture technology is the area where further studies are the most needed in Korean architecture history. This present study deals with architectural tools and woodworking of Baekje as a first step in exploration of Korean architecture technology history especially, that of Baekje dynasty. Based on the study of real artifacts and archeological sites showing the trace of tool use, function and forms of architectural tools were classified, characteristics of tools investigated, and woodworking technology analyzed. The main tools of analysis include Square, Black Inkpot, Hatchet, Saw, Chisel, Wood Hammer, Axe, and Plane. It is assumed that architectural technology during Baekje dynasty might have leapt into the new stage thanks to the regular use of iron tools. Compared to those of previous eras, iron tools of Baekje are more elaboratedly-designed and well-defined in function. In addition, wooden architectural tools from Baekje demonstrate the superiority of its woodworking technology Historical record also shows the fact that craftsman from Baekje participated in construction of temples of Shilla and Japan. Precise assessment of Baeje architecture technology is difficult because no Baekje wooden architecture is still remaining. The facts mentioned above, however, surely prove the excellence of architecture technology of Baekje.

Reproductive and life history patterns of marine amphipods are influenced by a variety of biotic and abiotic factors. Those factors may vary on local scales or along geographic patterns and result local or geographic variations in reproduction and life history. Although many studies in life history of amphipods were carried out at various habitats, limited information on the life history and reproduction at a shallow sandy shore 〈 1 m depth is available (Bear and Moore, 1996).

The history of the Bakken Museum, the Museum of Electricity in Life, is useful to understand the universality and particularity of a local science museum. Beginning with the small collections at the medical device company, the Bakken Museum has expanded its scope and facilities by reidentifying its mission from research institute to educational center. The educational turn of the Bakken Museum has been completed with two remarkable events: the launch of the Summer Institute in 1984 and the construction of the new education facility, New Wing, in 1999. During this change, the museum staff developed unique strategies for public engagement, using the history of science and technology as an educational tool. The shift of the Bakken Museum's mission provides an excellent example of how a local museum could meet the social needs for museums to be educational centers by utilizing its history and collections.

In this paper, we present a CNN-based gesture recognition approach which reduces the memory burden of input data. Most of the neural network-based gesture recognition methods have used a sequence of frame images as input data, which cause a memory burden problem. We use a motion history image in order to define a meaningful gesture. The motion history image is a grayscale image into which the temporal motion information is collapsed by synthesizing silhouette images of a user during the period of one meaningful gesture. In this paper, we first summarize the previous traditional approaches and neural network-based approaches for gesture recognition. Then we explain the data preprocessing procedure for making the motion history image and the neural network architecture with three convolution layers for recognizing the meaningful gestures. In the experiments, we trained five types of gestures, namely those for charging power, shooting left, shooting right, kicking left, and kicking right. The accuracy of gesture recognition was measured by adjusting the number of filters in each layer in the proposed network. We use a grayscale image with 240 × 320 resolution which defines one meaningful gesture and achieved a gesture recognition accuracy of 98.24%.

In the Japanese colonial period of Korean history, appropriate conclusion often overwhelmed the historical imagination, and also pointed out that it shows a similar pattern in spite of the history detective novel genre that emerged with pointing out the limitations of modern history. Historical facts showing in , the legitimacy of independence based on nationalism, and modern civilization are well known in the historical and cultural contents of the Japanese colonial period. It is the reason why applied in historical and cultural contents, as the history as is for current desire of the public to the imaginary community(nation), and as the history which current social conflicts are reflected. History, historical facts and fiction are intermingled in the contents of history, and it is creating a new 'historical imagination'. As a matter of fact, there is only one fact of the past, but the historical imagination of historical and cultural contents is diverse as there is not one historical fact made by historians. History has not yet gone to the imagination for the future, but writing history through historical and cultural contents will create a 'history of possibilities'.

The Mechanical properties of steel in hot strip mill were associated with the alloy composition, plastic deformation, cooling history and so on. In the case of the same alloy composition and deformation conditions, cooling history on ROT (run out table) is the main factor in affecting mechanical properties of steel, especially, in carbon steel. On ROT, the steel undergoes under various kinds of cooling conditions such as radiation, convection by air, water and wetting zone. The coiling temperature (CT) of the steel is also important factor in affecting mechanical properties. But with the same CT, the mechanical properties of steel can be different because the temperature history of cooling is more important factor than CT itself. In this study, we have studied the relations between temperature history and mechanical properties of steel and then the predicted mechanical properties have compared with the measured values.

In order to study the performance of levees reinforced with steel sheet piles under high water condition, a series of model tests was conducted by simulating the high water condition before and after applying severe seismic loading history. As a result, the seepage behavior through the subsoil layers underlying the levee was not significantly affected by the seismic loading history. It was also verified that, irrespective of the seismic loading history, the sheet piles installed at the levee crest or shoulder are effective in preventing the breakage of levees caused by overflow. In addition, applicability of drainage works at the foot of the levee in preventing the seepage failure was confirmed.

With the discovery of metabolic mechanisms of alcohol fermentation and acetic acid fermentation in the 1800s and 1900s, the history of traditional vinegar became a turning point for changing to the history of science and technology. Since then, innovation in vinegar production has occurred, and the era of full-scale mass industrialization has opened. The most modern method, submerged fermentation, has improved the vinegar production process to produce much higher quality vinegar and provide vinegar with high productivity and quality uniformity. Innovative research for vinegar production is underway as various approaches have been developed to increase fermentation efficiency, reduce costs, and shorten fermentation time due to the trend of combining existing technologies and advanced technologies. Now that the development of the vinegar industry is currently focused on vinegar engineering, multidisciplinary approaches in various fields such as microbiology, chemistry, food technology, process engineering, and molecular biology are needed.

The history of architectural acoustics is a part of history of human being getting together for both politics and entertainments, is also a part of the history of nobility pursuing hearing enjoyments, is still a part history of scientists deeply understanding the concept of "just for people", and as well as is a part history ceaselessly driven by the musicians to find their real hearts through music. The history of architectural acoustics explains not only the acoustic knowledge developments in architectural design, but also the unity on contradictory of both the science and the arts, both the technology and the culture, both the sense and sense organ. The history of architectural acoustics prints the interactions between the mankind and the nature, between the mankind and themselves, between the mankind and their souls, in which course people understand their feelings more deeply and deeply. This paper discusses the brief history of architectural acoustic in China from the ancient drama stages to grand theaters in 20 century, even up to nowadays, including some most important buildings and events as well.

This study summarizes the research methods, subjects, research processes, and achievements of major researchers by analyzing previous research results on Korean food history. The goal of the current study aimed to seek the methodology and direction of 'food history research'. Literature data from 1945 to 2022 were examined. Results of excavation research on ancient food literature were divided into the following stages: the 1980s, when the foundation for 'cataloging' was laid, and the 2000s, when 'digitization' was achieved. Achievements of each period were collected, and the achievements and limitations were analyzed. Next, the research results were classified into 'Food technology history', 'Recipe change history', and 'Food culture and dietary history'. We observed that around the 2000s, anthropology and folklore research perspectives were reflected, and the research on 'history of diet' reached a turning point. Our results indicate the possibility that food history can develop as a special historical area. This could be achieved by establishing an exchange system with other disciplines and creating a systematic curriculum.
