This study aims to explore mathematics teachers' pedagogical design capacity. For this purpose, we googled and collected 327 lesson plans for middle-school mathematics and investigated how mathematics teachers plan and design their mathematics lessons through the format and structures, objectives and mathematical tasks, anticipation for students' thinking, and assessment and technology use. The findings from the data analysis suggest as follows: a) all the lesson plans are structured in a very similar way; b) the lesson plans seem to be based on the textbooks exclusively, that is, the mathematical tasks and flow is strictly followed and kept in the lesson plans in the way the textbooks suggested; c) the lesson plans do not include any evidence of what teachers anticipate for students' thinking and would do to resolve the students' issues; and d) the lesson plans do not contain any specific plans to assess students' thinking processes and reasoning qualitatively, and not intend to use technology in order to promote effective teaching and meaningful understanding.

Recently, wireless networks require an efficient handover scheme due to increase of mobile devices. But Bluetooth has several problems to support the efficient handover, which are the additional increase of signaling traffic and long time of the initial setup processes of inquiry and paging processes. This paper suggests an efficient Soft Handover method for Bluetooth (eSoHoB), which reduces the eplased time of the inquiry and paging process and supports a soft handover using the anticipation method. This paper implements the eSoHoB using two Bluetooth hardware modules and a testbed to be able to receive streaming data while a Bluetooth terminal is moving. This paper measures handover delays and the operation of the soft handover to verify the proposed mhthod.

This study was performed to present new insights into the distinct aspects of Jehotang. Its history, significance, and effects were examined by evaluating the pertinent literature. In which the idea that Korean foods were original sources of medicine was well expressed. This study was also conducted with the anticipation that it may be useful in developing new foods and beverages based on modern science. References to the Jehotang were found in nine Korean medicine books, seven general books, and in dynastic records such as Bibyeonsa deungnok, Joseonwangjosilrok, Seungjeongwon Ilgi, etc; thus, it was likely a food since the early Korean age. Furthermore, it was discovered that in the Chosun era. Jehotang was not only drunk as a soft drink at the Royal Court in the summer, but was also used as a royal gifts to Cabinet members at the Tano festival on the fifth day of the fifth month of the lunar calendar.

In this paper, university hospitals, general hospitals/hospitals, private clinics, Chinese medicine hospitals and clinics in Seoul. Metropolitan Inchon, Kyunggi-do were probed to find out how the variables of service task factor are related to customer satisfaction, and to find out the determinants of medical service task(tangible quality, flexibility, cost, time and managerial skills), and anticipation factors, and respective items of customer satisfaction through statistical analysis. The meaning of the above mentioned findings should be carefully understood and construed due to the following problems. Because the factors why patients select hospitals were measured limitedly. it cannot show everything I intended to suggest. Especially due to the insufficient number if items. customer satisfaction variables are too limited. Reflecting the developing changes in various medical environments, hospitals could meet the objective of maintenance and prosperity only by facing the competition effectively and satisfying patients. Also hospitals should pursue patient-oriented service management. In other words, a strategic management of service task factors is needed. Based on this paper's research. a further study should be conducted continuously in order to give customers more satisfaction.

The imbalance of energy demand and supply caused by rapid industrialization around the world and the associated environmental issues require and alternative energy source with possible renewable fuels. Political instability and depletion of cruel oils are other factors that cause fluctuation of oil price. Securing a new alternative energy source for the next century became an urgent issue that our nation is confronting with. As a matter of fact, the fuel cell technology can be widely used as next generation energy regardless of regions and climate. Specially, the ability of expansion and quick installation enable one to apply it for distributed power, where the technology is already gaining remarkable attentions for the application. Particularly, leading industrialized nations are focusing on the PEM fuel dell with anticipation that this technology will find their place of applications in the vehicles and homes. In this study, demonstrate the multi physics modeling of a proton exchange membrane(PEM) fuel cell with interdigitated flow field design. The model uses current balances, mass balance(Maxwell-Stefan diffusion for reactant, water and nitrogen gas) and momentum balance(gas flow) to simulate the PEM fuel cell behavior.

Magnetic fluid seal is characterized by its simple design, low friction and being dustless. Those advantages are deduced from the fact that the sealing element is not a solid such as rubber or plastic but it is a fluid. Those are critical for application to a rotating shaft which is inserted into a vacuum chamber where high level of vacuum and cleanness are required. For the reason the magnetic fluid seal has become a standard for vacuum chambers for semiconductor and LCD processing. It should be noted that its sealing performance is sensitive to temperature. If necessary, water cooling should be considered. Thus anticipation of the temperature distribution of the magnetic fluid seal is important before applying it. In this paper an FEM analysis of the heat transfer has been executed and compared with experimental results. An overall convective heat transfer coefficient has been adopted for the analysis, which results in satisfactory consistency of the theoretical and experimental results.

In this paper, we analyze the buyer's joint pricing and lot-sizing model in a two-stage supply chain consisting of the supplier, the buyer and the customer. It is assumed that the supplier will permit a certain fixed period for settling the amount the buyer owes to him for the items supplied in order to stimulate the demand for the product. Generally, credit transactions would have a positive effect to the buyer. The availability of credit transactions from the supplier effectively reduces the cost of holding stocks for the buyer and therefore, the buyer has a lot of price options to choose his sales price for a customer in anticipation of increased the customer's demand and, as a result, it will appear to increase the buyer's inventory levels. On the other hand, in the case of decaying products in which their utility decay over time, the decaying rate with time may be expected to reduce inventory levels. In this regard, we need to analyze how much the length of credit period and the decaying rate affect the buyer's pricing and lot-sizing policy. For the analysis, we consider the situation where the customer's demand is represented as a linearly decreasing function of the buyer's sales price. From this perspective, we formulate the buyer's annual net profit and analyze the effect of the length of credit period and decaying rate of the product on the buyer's inventory policy numerically.

The purpose of this study is to show the component and anticipation factors of loyalty and word-of-mouth. Specifically, hypothesis is that trust in a salesperson will influence satisfaction with the salesperson, and the store. And the satisfactions with the salesperson and the store will influence the loyalty to the salesperson and the store. Another hypothesis is that loyalty to a salesperson and a store will influence word-of-mouth. Scale items used in this study were selected from developed scales and were adapted to conforming to the selling situation in the service setting. Factor analysis and Cronbach's alpha test were accomplished. A total of 703 samples was used to test the hypotheses. The primary method of statistical analysis to test the hypotheses was a structural equation modeling on LISREL 8.3. The results of the study are as follows: First, trust had an influence on satisfaction with a salesperson and a store. Second, the results suggested that satisfaction with the salesperson and the store influences loyalty to the salesperson and the store. Finally, loyalty to the salesperson and the store influenced word-of-mouth, as predicted.

The purpose of this study was to explore the structures of consciousness on the experiences of formation and adjustment in multicultural families. A qualitative study was designed in this article. The research participants were 10 dyads of immigrant married women and their mothers-in-law. Before the marriage, the mother-in-law's expectation about her daughter-in-law was not high, and the daughter-in-law held the same opinion of her mother-in-law. During the marriage process, the mother-in-law had difficulties in terms of physical, emotional, and material aspects. The daughter-in-law endured the wedding procedure by holding onto hope and anticipation for the future. After the marriage, the mother-in-law eventually became satisfied with her daughter-in-law, and the daughter-in-law grew to feel thankful for her new family members and expressed that she was living a happy life. Consequently, the essence of formation and adjustment in multicultural families was "obtaining precious family members through the undergoing of trial and error."

We investigated the neural representation of reward probability recognition and its neural connectivity with other regions of the brain. Using functional magnetic resonance imaging (fMRI), we used a simple guessing task with different probabilities of obtaining rewards across trials to assay local and global regions processing reward probability. The results of whole brain analysis demonstrated that lateral prefrontal cortex, inferior parietal lobe, and postcentral gyrus were activated during probability-based decision making. Specifically, the higher the expected value was, the more these regions were activated. Fronto-parietal connectivity, comprising inferior parietal regions and right lateral prefrontal cortex, conjointly engaged during high reward probability recognition compared to low reward condition, regardless of whether the reward information was extrinsically presented. Finally, the result of a regression analysis identified that cortico-subcortical connectivity was strengthened during the high reward anticipation for the subjects with higher cognitive impulsivity. Our findings demonstrate that interregional functional involvement is involved in valuation based on reward probability and that personality trait such as cognitive impulsivity plays a role in modulating the connectivity among different brain regions.
