The widespread use of smart phones and smart pads has given rise to the use of eBook services based on these smart devices. Consequently, the size of eBook services has exploded both in the domestic as well as overseas market. However, the growth curve becomes flatter than before, and the adoption rate is still not high in Korea. Hence, this study explores the factors affecting the intention to use eBook services based on smart devices, and their relationships. Finally, we propose an eBook adoption model, which extends the Technology Adoption Model. An online survey was conducted to validate the research model. By applying Partial Least Squares, we found that there are strong relationships among perceived usefulness, perceived ease of use, perceived playfulness, social influence, and intention to use. In addition, we found that smart devices enjoyment positively affects the perceived playfulness of eBooks, and that personal innovativeness positively affects perceived ease of use. Our findings shed some light on how to design eBook services based on smart devices.

Reverse Osmosis (RO) desalination has gained wide and increasing acceptance around the world as a straightforward undertaking to alleviate the alarming water crisis. An enhanced monitoring of the quality of the water feeding in seawater RO (SWRO) plant through the application of an effective pretreatment option is one of the keys to the success of RO technology in desalination plants. Over the past 10 years, advances in ultrafiltration (UF) membrane technologies in application for water and wastewater treatment have prompted an impetus for using membrane pretreatment in seawater desalination plants. By integrating SWRO plant with UF pretreatment, the rate of membrane fouling can be significantly reduced and thus extend the life of RO membrane. With the growing importance and significant advances attained in UF pretreatment, this review presents an overview of UF pretreatment in SWRO plants. The advantages offered by UF as an alternative of pretreatment option are compared to the existing conventionally used technologies. The current progress made in the integration of SWRO with UF pretreatment is also highlighted. Finally, the recent advances pursued in UF technology is reviewed in order to provide an insight and hence path the way for the future development of this technology.

The Electro-optical camera subsystem as a payload of a satellite system consists of OM (optical module) and CEU(camera electronics unit), and most performances of the camera subsystem depend a lot on the CEU in which TDI CCDs(Time Delayed Integration Charge Coupled Device) take the main role of imaging by converting the light intensity into measurable voltage signal. Therefore it is required to specify and design the CEU very carefully at the early stage of development with overall specifications, design considerations, calibration definition, test methods for key performance parameters. This paper describes the overview of CEU development. It lists key requirement characteristics of CEU hardware and design considerations. It also describes what kinds of calibration are required for the CEU and defines the test and evaluation conditions in verifying requirement specifications of the CEU, which are used during acceptance test, considering the fact that CEU performance results change a lot depending on test and evaluation conditions such as operational line rate, TDI level, and light intensity level, so on.

Membrane technology has gained tremendous acceptance by industry in recent years. A long dormant period of laboratory research in academia and industry has evolved into a new era of commercial growth. The total sale of membranes is still modest compared to the major technologies, yet it is one of the fastest growing industries. This can be best illustrated by inspecting the market place. In 1990, the total sales of worldwide membranes was estimated to be approximately $ 1.6 billion with an annual increase rate of 15%. This means that the estimated total sales of membrane based industry is nearly $ 5 billion annually. Equally important evidence is an increase in research activities, as demonstrated by the explosion of publications and proliferation of membrane meetings. A number of research centers have sprung up around the world in addition to newly emerging membrane companies and membrane research groups eventually translated into some form of publication. As an example of the rapid growth in membrane research, the number of papers submitted to the Journal of Membrane Science alone was almost 2000 and the number of papers accepted was over 1300 in 1990.The worldwide membrane research expenditure in 1990 was estimated to be around $ 127 million consisting of $ 76 million(60%) by industry and $ 51 million by governments, which can be broken down to $11 million in the U.SA., $ 20 million in Japan, and $ 20 million in Europe.

In this paper, we proposed the compensation technique that overcomes the limitations of the conventional approaches through summing up the bias terms between world's codebook and individual codebook vectors of feature parameters. But, mean compensation without condition can bring higher false acceptance. Therefore, the proposed technique compensates the channel mis-match condition by weighted bias sum using nonlinear function regarding to the distortion between speech and silence. The simulation results show that the FRR (flase reject rate) is decreased 14.95% when the proposed algorithm was applied.

This study was designed to investigate the effect of Korean whole wheat flour making pan bread. Korean whole wheat flour was mixed with flour at the level of 10% (WHF10), 20% (WHF20), 30% (WHF30), 40% (WHF40) and 50% (WHF50) in order to make bread. According to mixogram, the CON (control), WHF10, WHF20, WHF30, WHF40, except WHF50 were found to be proper between 3 and 5 min. in terms of peak time. CON and WHF10 for peak value were at the level of over 60%. By increasing the ratio of Korean whole wheat flour, the pH, dough fermentation rate, volume, specific volume and moisture content were decreased, and gumminess, cohesiveness and hardness except springiness, were increased for storage days. In the crumbScan analysis, the addition of Korean whole wheat flour decreased the volume and increased the crumb fineness of pan bread. In the sensory evaluation, WHF30 showed good preference in the aspect of flavor, taste and overall acceptance, but was not significant between WHF20. CON scored the highest points in volume, specific volume, moisture content and texture, but was not significant between WHF20.

This study investigated the quality characteristics of muffins by the amount of addition of suchero (0%, 25%, 50%, 75%, 100%) as there is increasingly higher interest in functional alternative sweetener. The effects of suchero were evaluated in terms of height, volume, weight, specific volume, baking loss rate, colorimeter, and sensory evaluation. Texture and moisture contents of muffins during storage (1, 2, 3 days) were measured. As the ratio of suchero increased, the volume, specific volume, and weight increased, whereas the volume and specific volume was not significant. During storage, moisture content of muffins decreased significantly. The moisture content of the sample containing suchero was higher than S0(control group). The addition of suchero increased L value of crust and crumb decreased, whereas a value and b value increased. The muffin with 100% of suchero (S100) in test group showed the lowest hardness. According to the sensory evaluation, the muffin with 50% of suchero (S50) showed the highest score in terms of appearance, color, flavor, taste, and overall acceptance, S50 showed the best result and the optimum addition of suchero.

The purpose of this study is to provide the systematic report and analysis about Apartment VE application in Design Phase. In this study, the method of VE application is classified into foure groups-changing materials, changing a method of construction, acceptance of new technology, and use of new device. The facts found in this study can be summarized as follows. Application rate of VE is highest in building circumference parts. The main reason would be that there are many applicable factors according to locations, types of work, etc. Parking lots also show similar results with the same reason. It means there are a lot of possibility to adapt value engineering in these steps during the work. So far application of value engineering has been so limited that just small changes of process or method have been tried. One reason is the lack of challenging and the other is some characteristics of construction work which is very difficult to fix after completion. In the future, it would be more efficient to apply new technology and new device in construction work. Though these attempts have been ignored in Korea so far, there are still lots of possibilities to be developed in value engineering.

The authors compared the basic characteristics of rural woman in relation to family planning for June 1967 and June 1969 in Kyung San County, Kyungpook Province, Korea. The statistics showed that these characteristics are gradually changing. The marriage age was slightly higher than the past year and the formal education of women increased. The ideal children number, and the gravidity and mortality rates decresed. At the same time the number of induced abortions, the knowledge of family planning, and the acceptance rate of contraception increased. These phenomena seem to follow the present worldwide trend.
