Large language models seem promising for handling reasoning problems, but their underlying solving mechanisms remain unclear. Large language models will establish a new paradigm in artificial intelligence and the society as a whole. However, a major challenge of large language models is the massive resources required for training and operation. To address this issue, researchers are actively exploring compact large language models that retain the capabilities of large language models while notably reducing the model size. These research efforts are mainly focused on improving pretraining, instruction tuning, and alignment. On the other hand, chain-of-thought prompting is a technique aimed at enhancing the reasoning ability of large language models. It provides an answer through a series of intermediate reasoning steps when given a problem. By guiding the model through a multistep problem-solving process, chain-of-thought prompting may improve the model reasoning skills. Mathematical reasoning, which is a fundamental aspect of human intelligence, has played a crucial role in advancing large language models toward human-level performance. As a result, mathematical reasoning is being widely explored in the context of large language models. This type of research extends to various domains such as geometry problem solving, tabular mathematical reasoning, visual question answering, and other areas.

The purpose of this study is to derive the factors for the general consumers to choose the store to buy seafood. Survey on 414 general consumers by questionnaires was conducted to find out the factors for them to choose the stores in the traditional market and large supermarket, and through the analysis on the results the factors for general consumers to choose large supermarkets were derived when they buy seafood and at the same time the degree of its importance was analyzed. The results of the survey showed that the general consumers chose large supermarkets to buy seafood despite the fact that they recognized the seafood prices are lower in the traditional markets than in the large supermarkets. Particularly, the results of analyzing the sixteen criteria for choosing the store in which to buy seafood were grouped into four: the 'assortment of goods and high quality', 'service', 'price and promotion' and 'convenient accessibility.' The results of examining the order of priority based on the four factors showed that the 'assortment of diverse seafood and high quality' was found to be given the first priority, followed by 'convenient accessibility' and 'prices and promotion factors', with 'service' being statistically insignificant. Based on these results, Monroe (1975)'s consumers' store choice process is summarized as follows. Before buying seafood, the consumers who use large supermarkets have the desire for buying seafood and then judge the properties of the store which they will use. In this process, consumers were satisfying their needs in large supermarkets in the criteria of 'assortment of diverse seafood and high quality', convenient accessibility', and 'prices and promotion factors' which were found to be statistically significant in this research. Accordingly, the general consumers choose to buy seafood in large supermarkets rather than in the traditional markets. The general consumers were more satisfied with using large supermarkets than using traditional markets, so after they have initially bought seafood in the large supermarkets, they habitually buy seafood in the large supermarkets without going through Monroe (1975)'s 'eight stage process for the store choice.' When such habitual store choice behavior continues for a long time, it results in becoming structural.

As the digital TV markets rapidly growing, many manufacturers introduce large size flat screen TV units. There are two different display types available to large size models which are plasma and TFT-LCD. Since both are constructed with thin large panels that are mostly fragile to even moderate mechanical shock inputs. Some large size panels are severely resonated by the acoustic sound generated TV which deteriorates video quality. Recognizing the potential problems of large displays, accurate measurement of the panels is to be an essential task for the reliable design. Measurement of mechanical properties of a thin large crystallized panel such as TFT-LCD display with traditional material testing equipments is challenging. Since TFT-LCDs are constructed with combination of brittle glass panels, polymer sheets, and liquid crystal, their properties are not only anisotropic but also usually non-linear. Accurate measurement of the properties often requires very expensive facilities. Especially when the size of the test sample is as large as 40-inch or wider, direct measurement cost is prohibitive. Even worse, machining of the large TFT-LCD to make a smaller size specimen that could be fit into a material tester is not possible because of liquid crystal leakage. A new method fer the measurement of elastic modulus of large TFT-LCD panel is presented in this article. The suggested method provides a simple, economic, and user-friendly way fer measuring the elastic modulus of large panels with considerable level of accuracy.

The main goal of this study is to investigate the free vibration analysis of a large sag catenary with application to the jumper in hybrid riser system. The equation of motion is derived by using the variational method based on the virtual work principle. The finite element method is applied to evaluate the numerical solutions. The large sag catenary is utilized as an initial configuration for vibration analysis. The nonlinearity due to the large sag curvature of static configuration is taken into account in the element stiffness matrix. The natural frequencies of large sag catenary and their corresponding mode shapes are determined by solving the eigenvalue problem. The numerical examples of a large sag catenary jumpers are presented. The influences of bending rigidity and large sag shape on the free vibration behaviors of the catenary jumper are provided. The results indicate that the increase in sag reduces the jumper natural frequencies. The corresponding mode shapes of the jumper with large sag catenary shape are comprised of normal and tangential displacements. The large sag curvature including in the element stiffness matrix increases the natural frequency especially for a case of very large sag shape. Mostly, the mode shapes of jumper are dominated by the normal displacement, however, the tangential displacement significantly occurs around the lowest point of sag. The increase in degree of inclination of the catenary tends to increase the natural frequencies.

We apply a partitioned-solution (iterative-staggered) coupling method based on a fixed Eulerian mesh with the level set function to a large-deformation fluid-structure interaction (FSI) problem where a large-deformable thin structure moves in a high-speed flow field, as an airbag does during deployment. This method combines advanced fluid and structure solvers-specifically, the constrained interpolation profile finite element method (CIP-FEM) for fluid Eulerian mesh and large-deformable structural elements for Lagrangian structural mesh. We express the large-deformable interface as a zero isosurface by the level set function, and introduce virtual nodes with level sets and structural normal velocities to generate the level set function according to the large-deformable interfacial geometry and enforce the kinematic condition at the interface. The virtual nodes are located in the direction normal to the structural mesh. It is confirmed that application of the method to unfolded airbag deployment simulation shows the adequacy of the method.

A 48-year-old man whose symptom had intermittent right chest pain and x-ray film revealed large mass on right mid lung fields was examined. A conclusive histological diagnosis of large cell neuroendocrine carcinoma was made following bilobectomy. Large cell neuroendocrine carcinoma is an uncommon pulmonary neoplasm, which is characterized by large cell size and low nuclear to cytoplasmic. This tumor shows prominent organoid nests of tumor cells with peripheral palisading and rosette-like structures. We experienced one case of large cell neuroendocrine carcinoma of lung and report it with references.

This paper presents a linear motor, which generates large thrust with a low operating rate. In industrial fields there is a need for actuators that work with a low duty cycle but generate large thrusts. An example of such a case is provided by the actuators for ejector mechanisms in electric injection molding machines. The ordinary LSM (linear synchronous motor) is unsuitable for this large-thrust and low-operating-rate usage, because of its large size and high cost. This paper contains experimental results on linear motors that can generate large thrusts for a short time, and which can be cheaply produced. The described linear motor could be contained space of $250mm \times250mm\times 250mm$ and generate a maximum thrust of about 20000 N at a current of 250 A.

실제 Cu CMP 공정이 진행되는 동안 연마입자의 응집현상을 관찰하긴 어렵다. 따라서 본 연구에서는 인위적으로 첨가한 large particle들이 공정 중에 발생하는 응집입자라 가정하고 각 공정에 따른 연마속도와 friction force를 측정하여 large particle을 첨가하지 않은 슬러리와 비교 평가해보았다. large particle을 첨가한 슬러리의 경우에 각 공정변수에 따라 연마속도와 friction force가 작아짐을 관찰하였다. 즉, 슬러리 내에 응집현상이 발생하게 된다면 large particle이 연마의 방해 인자로 나타남을 관찰 할 수 있었다.

It is very difficult to accomplish load tests of piles with large diameter constructed on the offshore area, because of requirement for large scaled loading equipment and bad testing conditions. Therefore, so far in many cases pile driving dynamic formulas have applied to quality control, and recently dynamic load test method is widely used for confirming bearing capacities of such piles. However, in cases of piles with very large diameter about 2,500mm, it is nearly impossible for regular type load test methods of piles such as static and dynamic to apply owing to very large design load. This is case studies of load tests such as modified static and dynamic load tests of piles and point load tests of rock samples for estimating rational allowable bearing capacity of very large diameter piles constructed on the marine area.

Large-scale failures resulting from natural disasters or intentional attacks are now causing serious concerns for communication network infrastructure, as the impact of large-scale network connection disruptions may cause significant costs for service providers and subscribers. In this paper, we propose a new framework for the analysis and prevention of network service disruptions in large-scale failure scenarios. We build dynamic deterministic and probabilistic models to capture the impact of regional failures as they evolve with time. A probabilistic failure model is proposed based on wave energy behaviour. Then, we develop a novel approach for preventive protection of the network in such probabilistic large-scale failure scenarios. We show that our method significantly improves uninterrupted delivery of data in the network and reduces service disruption times in large-scale regional failure scenarios.
