This study, from the perspective of Learning with AI, aimed to explore the educational applicability of writing evaluation criteria generated by artificial intelligence. Specifically, it sought to systematically analyze the similarities and differences between AI-generated criteria and those developed by humans. The research questions for this study were set as follows: 1) What characteristics do the writing evaluation criteria generated by AI tools have? 2) What similarities and differences exist between the writing evaluation criteria generated by humans and AI tools? GPT and Claude were selected as representative AI tools, and they were tasked with generating writing evaluation criteria for undergraduate students. These AI-generated criteria were then compared with human-created criteria. The results showed a commonality: Both humans and AI-tools placed the highest importance on categories related to content. However, while humans evaluated based on three main categories - content, organization, and language usage - the AI tools included additional categories such as format and citations, original thinking, and overall impression. In general, human tended to include more detailed items within each evaluation category, while AI tools presented more concise items. Notably, differences were observed in language-related aspects and scoring systems, which were influenced by the AI tools being developed based on English. This study offers important insights into the development of collaborative evaluation models between humans and AI, and it explores the potential role of AI as a complementary tool in educational assessment in the future.

This is an introduction to a stochastic version of E. Cartan′s symplectic mechanics. A class of time-symmetric("Bernstein") diffusion processes is used to deform stochastically the exterior derivative of the Poincare-Cartan one-form on the extended phase space. The resulting symplectic tow-form is shown to contain the (a.e.) dynamical laws of the diffusions. This can be regarded as a geometrization of Feynman′s path integral approach to quantum theory; when Planck′s constant reduce to zero, we recover Cartan′s mechanics. The underlying strategy is the one of "Euclidean Quantum Mechanics".

Nanocrystalline silicon (nc-Si) based TFTs were developed using a conventional PECVD production system. Devices exhibit very interesting characteristics, in particular when using a bi-layer structure which reduces leakage current and improves subthreshold area. Good stability and low leakage current make these devices suitable for the fabrication of low-cost and high performance AMOLED displays.

It is shown that if $A{\geq}0$ and T are two bounded linear operators on a complex Hilbert space H satisfying the inequality $T^*\;AT{\leq}A$ and the condition $AT=A^{1/2}TA^{1/2}$, then there exists the maximum reducing subspace for A and $A^{1/2}T$ on which the equality $T^*\;AT=A$ is satisfied. We concretely express this subspace in two ways, and as applications, we derive certain decompositions for quasinormal contractions. Also, some facts concerning the quasi-isometries are obtained.

Surface mould ripened soft cheeses such as Camembert are characterized by the presence of a felt-like coating of white mycelia due to the growth of Penicillium camemberti at the surface. The presence of this mould gives these cheeses a different appearance, as well as a typical aroma and taste. It also lead to a more complex ripening than in other varieties of cheese with simple flora. Theses cheeses are becoming increasingly popular with consumer and there is an increasing demand for them.

Premixes treated with a binder, such as in the FLOMET process, exhibit better flow, reduced dusting and segregation and improved productivity and part consistency compared to conventional premixes. The binder treatment is highly suitable for high performance P/M applications which often require premixes containing very fine alloying additives and excellent die filling characteristics. With this process, various binders and lubricants can be utilized in order to make premixes with unique properties. In this paper, the characteristics and performances of bonded premixes are reported.

A wide range of data is available as too causes of large power transformers. Although the percentage of transformer component failure rates vary, all data shows that the top three failure mechanisms are Load Tap Changers (LTC), Bushings and Windings. To date, the most common methods employed to determine the health of a transformer are off line tests and online temperature monitoring, winding hotspot calculations and dissolved gas analysis.

In this paper, an effective method of stereo image reconstruction through the regularized adaptive disparity estimation is proposed. Althougth the conventional adaptive disparity estimation method can sharply improve the PSNR of a reconstructed stereo image, but some problems of overlapping between the matching windows and disallocation of the matching windows can be occurred, because the matching window size changes adaptively in accordance with the magnitude of feature values. Accordingly, in thia paper, a new regularized adaptive disparity estimation technique is proposed. That is, by regularizing the estimated disparity vector with the neughboring disparity vectors, problems of the conventional adaptive disparity estimated scheme might be solved, and also the predicted stereo image can be more effectively reconstructed. From some experiments using the CCETT'S stereo image pairs of 'Man' and 'Claude', it is analyzed that the proposed disparity estimation scheme can improve PSNRs of the reconstructed images to 10.89dB, 6.13dB for 'Man' and 1.41dB, 0.81dB for 'Claude' by comparing with those of the conventional pixel-based and adaptive estimation method, respectively.

A quest in MMORPG functions as a unit of game narrative. It is an essential part to progress game narrative and to construct player's own storyline. In addition, it makes player to expand her territory and helps with character growth by giving reward. A quest consists of four essential elements : the quest giver, the background story, the objective and the reward. A quest shows a blanch structure with two nodes which is same as Claude Bremond's elementary sequence. The sequence of each functions cannot be changed, therefore, it can be explained through a syntagma model. On the other hand, spatial disposition of quests follows a paradigm model. In order to construct a MMORPG narrative, a player connects quests into a single narrative by carrying out them.

The first attempt in architectural design theory to consider the perceptual and metaphysical dimension separately with a fully modern scientific manner, which exist in contrast to the Renaissance idea, was Claude Perrault, who emphasized the cognitive factors as an important scientific human issue in building design in 1683 in his book "Ordonnance". Even today many elaborated works to reveal the mysterious design processes based on a set of rational approaches have been introduced since the Design Method movement in 1960's. Their pioneering and challenging efforts to rationalize design process have been mostly rely on the cultural issues whether it takes a qualitative or quantitative stance. On the other hand, however, today's computer generated free form architecture seems not to be aware of those lessons learned from the past and, therefore, this study conducted an extensive research through exploring on morphological building forms with cultural issues to fill up the missing and/or lacking characteristics of today trend in building design.
