  • On 21 August 2017, during 16:49 UT and 20:02 UT period, a total solar eclipse started. The totality shadow occurred over the United States in time between ~17:15 UT and ~18:47 UT. When the solar radiation is blocked by the moon, observations of the ionospheric parameters will be important in the space weather community. Fortunately, during this eclipse, two Swarm satellites (A and C) flied at about 445 km through lunar penumbra at local noon of United States in the upper ionosphere. In this work, we investigate the effect of the solar eclipse on electron density, slant total electron content (STEC) and electron temperature using data from Swarm mission over United States. We use calibrated measurements of plasma density and electron temperature. Our results indicate that: (1) the electron density and STEC have a significant depletion associated with the eclipse; which could be due to dominance of dissociative recombination over photoionization caused by the reduction of ionizing extreme ultraviolet (EUV) radiation during the eclipse time (2) the electron temperature decreases, compared with a reference day, by up to ~150 K; which could be due to the decrease in photoelectron heating from reduced photoionization.

  • The modern era of water quality modeling in the United States began in the 1960s. Pushed by advances in computer technology as well as environmental sciences, water quality modeling evolved through five broad periods: (1) initial model development with mainframe computers (1960s - mid 1970s), (2) model refinement and generalization with minicomputers (mid 1970s - mid 1980s), (3) model standardization and support with microcomputers (mid 1980s - mid 1990s), (4) better model access and performance with faster desktop computers running Windows and local area networks linked to the Internet (mid 1990s - early 2000s), and (5) model integration and widespread use of the Internet (early 2000s - present). Improved computer technology continues to drive improvements in water quality models, including more detailed environmental analysis (spatially and temporally), better user interfaces and GIS software, more accessibility to environmental data from on-line repositories, and more robust modeling frameworks linking hydrodynamics, water quality, watershed and atmospheric models. Driven by regulatory needs and advancing technology, water quality modeling will continue to improve to better address more complicated water bodies and pollutant types, and more complicated management questions. This manuscript describes historical trends in water quality model development in the United States, reviews current efforts, and projects promising future directions.

  • Under U.S. Antidumping law, dumping occurs when 'subject merchandise' is imported into the United States and sold at less than 'fair value'. The administration of U.S. antidumping law is shared between the U.S. Department of Commerce(USDOC) and the U.S. International Trade Commission(USITC). USDOC's task is to determine whether imports are being dumped, and if so, to estimate the margin of dumping. In determining whether an industry in the United States is materially injured or threatened with material injury, or the establishment of an industry in the United States is materially retarded, by reason of the subject imports, the USITC must first define the 'like product' and the 'domestic industry'. One of the crucial factors on antidumping measures is the interpretation's scope of the 'like product' and the 'domestic industry', leading the most controversial issues in U.S. antidumping law. The primary purpose of this paper is to examine the 'domestic industry' and 'like product' considering U.S. antidumping law. Most USITC's determinations regarding like product and industry as flexible conception have been supported by the U.S. Courts.

  • The purpose of this research starts analyzing the case with the United States and Japan and considering the plan form of educational facilities in the advanced country for the improvement of educational facilities in our counties. Japan was managing the educational system which carried out homogeneous till the first stage of the 1970s like advanced nations, such as the educational system of the industrialization age before World War II, i.e., Britain and the United States. The form of an American open school was adopted after the second half of the 1960s, trying the educational system which also globalized the educational system of Japan while the world went into the information society. In the process of the introduction, Japan did not simply imitate a huge open space in the United States. Japan selected the content of the education carefully. And, to do an original educational activity by guidance. The current classroom and multipurpose space were planned as one body. As a result, the environment of the classroom was able to do various studying patterns of individual study and the group study.

  • This paper utilized a Korean time-use survey and household expenditure survey in designing an input-output table to develop satellite accounts of household production in Korea in 1999. Additionally, the household production in Korea was compared with that in the United States, Australia, Finland, and Canada. Results of this study may be summarized as follows. First, household production in Korea represented $43\%$ of Gross Domestic Product (GDP,) compared to $63\%$ of GDP in the United States, $68\%$ in Australia, $58\%$ in Finland, and $54\%$ in Canada. Second, labor emerged as the largest input for household production in Korea, while materials and services - both intermediate goods - emerged as the second input. On the other hand, the proportion of housing among the four inputs of household production in Korea was greater than for either the United States or the other countries studied. This implies that the cost of intermediate goods and housing in Korea is more expensive than in other countries.

  • Monitoring the performance and estimating the remaining useful life of aging civil infrastructure in the United States has been identified as a major objective in the civil engineering community. Structural health monitoring has emerged as a central tool to fulfill this objective. This paper presents a review of the major structural monitoring programs that have been recently implemented in the United States, focusing on the integrity and performance assessment of large-scale structural systems. Applications where response data from a monitoring program have been used to detect and correct structural deficiencies are highlighted. These applications include (but are not limited to): i) Post-earthquake damage assessment of buildings and bridges; ii) Monitoring of cables vibration in cable-stayed bridges; iii) Evaluation of the effectiveness of technologies for retrofit and seismic protection, such as base isolation systems; and iv) Structural damage assessment of bridges after impact loads resulting from ship collisions. These and many other applications show that a structural health monitoring program is a powerful tool for structural damage and condition assessment, that can be used as part of a comprehensive decision-making process about possible actions that can be undertaken in a large-scale civil infrastructure system after potentially damaging events.

  • As the cities developed and grew into larger metropolises, land value grew and land invariably became an asset. One of very critical causalities of such widespread need for development was the urban residence that got converted into cesspools of urban slum, major crime area and rapidly degraded. Incessant population growth of these cities called for more land to build residences especially the economically affordable and safe housings were needed for the citizens of none or low-income community. However, not enough attentions have yet been given to the essential basics of human habitation that exist within metropolitan limits by social, economical and political aspects. The following paper studies and elaborates the development motivation adopted by the government to develop public housing in the United States under the technical guidance of supporters and developers from national and international communities. The paper discusses current situation of public housing in the United States with a focus on understanding the present status of public housing and physical condition of their surroundings, strategies for fund mobilization, types of local involvement and community participation, ways of continuous monitoring and maintenance, etc. thereby creating a self-sustaining and integrated management plan for public housings in the future.
