This survey was conducted to investigate liberal arts college students' academic reading, to explore basic issues in their reading, and to provide how to improve their academic reading in their majors. The participants in this study were 457 students who enrolled in a college of liberal arts in a university. The study results represented as follows. Firstly, there were significant differences in vocabulary, reading comprehension, and fast-reading competence among student groups of different majors. Secondly, 66.9% of the students did not read widely in their major subjects throughout all departments. 67.7% of the students with low reading performance responded that they could complete college courses only with course textbook reading, course participation, and requirement submission. Thirdly, regarding the number of major subject books that the participants read, 82.1% of the students read less than 15 books, while 11.3% read less than a book. The students' academic reading hours during per week were less than 5 hours for 68.9% students and less than 10 hours for 13.9% respectively. Based on the results (departmental differences in reading competence, wide reading in major subject books, and liberal arts students' reading hours), liberal arts colleges need to design programs to guarantee quality and quantity in reading major subject books.

Quantities of data in the DMS (Distribution management system) or SCADA (Supervisory control and data acquisition) system is enormously large as illustrated by the usage of term flooding of data. This enormous quantity of data is transmitted to the status data or event data of the on-site apparatus in real-time. In addition, if GIS (Geographic information system) and AMR (Automatic meter reading), etc are integrated, the quantity of data to be processed in real-time increases unimaginably. Increase in the quantity of data due to addition of system or increase in the on-site facilities cannot be handled through the currently used Single Thread format of data processing technology. However, if Multi Thread technology that utilizes LF-POOL (Leader Follower -POOL) is applied in processing large quantity of data, large quantity of data can be processed in short period of time and the load on the server can be minimized. In this Study, the actual materialization and functions of LF POOL technology are examined.

The study investigates the effects of online instructional facilitator's qualities on student performance of online class activities. The study explores the roles of instructional facilitators who may influence student performance of online class activities and their academic achievement. The study employs a set of aggregated data from 1,362 subjects and 10 facilitators who participated in multiple online classes. The results of independent samples t-test reveal that the student performance in online classes has no association with facilitators' educational background or academic degree, as well as demographic characteristics, student evaluation records and instructional achievement. The results of multiple regression analysis show that the facilitator engagement has a positive relation to the enhancement of student interaction, reading discussion messages, and the quality of discussion messages in online discussions. The results of correlation analysis show that the facilitator engagement has a positive impact on both increasing the number of reading discussion messages and enhancing the quality of discussion messages. The facilitator engagement increases the quantity of reading discussion postings and enhances the quality of discussion messages, which would be a substantial contribution to student performance by facilitators. The findings suggest that student performance and academic achievement in online classes are not independent of facilitator engagement.

There is a growing concern in reducing greenhouse gas emissions all over the world. The U.K. has set 34% target reduction of emission before 2020 and 80% before 2050 compared to 1990 recently in Post Copenhagen Report on Climate Change. In practise, Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) tools have been introduced to construction industry in order to achieve this such as. However, there is clear a disconnection between costs and environmental impacts over the life cycle of a built asset when using these two tools. Besides, the changes in Information and Communication Technologies (ICTs) lead to a change in the way information is represented, in particular, information is being fed more easily and distributed more quickly to different stakeholders by the use of tool such as the Building Information Modelling (BIM), with little consideration on incorporating LCC and LCA and their maximised usage within the BIM environment. The aim of this paper is to propose the development of a model-based LCC and LCA tool in order to provide sustainable building design decisions for clients, architects and quantity surveyors, by then an optimal investment decision can be made by studying the trade-off between costs and environmental impacts. An application framework is also proposed finally as the future work that shows how the proposed model can be incorporated into the BIM environment in practise.

In order to investigate the recognition of processed foods, use of food labeling, and their influencing factors in adolescents, 277(male 125, female 152) middle school students were conveniently selected from Cheonan city, and were surveyed by self-recording questionnaire on June, 2000. Subjects' parents were also surveyed using the similar questionnaire. Food labels of all 222 processed foods collected from stores around schools, were well labeled in most items, but food additives(35.6%) and the origin of major ingredient(27.0) were not well indicated. The recognition score of processed foods was 55.0 out of a full score 100 in students and 68.5 in parents. The scores of students were positively correlated with those of their parents and with father's education years, while negatively correlated with snacking expenses. The rate of reading food labels was significantly different between students(51.3%) and their parents(89.9%). The main purposes of reading food labels, in case of students, were to check expiry date(93.7%), price(70.4%), and how to eat(46.5%) in order. While in parents, those were to check expiry date(95.6%), additives(59.0%), and manufacturer(45.8%). Similarly, the most three important items in food labels were expiry date, price, and quantity to the students, but to the parents they were expiry date, manufacturer, and ingredient. The most significant reason not to confirm food labels was because of small size and complication of labels. The students who did not read food labels had more snacking money and more frequent snacking, and showed lower recognition score of processed food, compared with the students who read food labels. In conclusion, the students did not well recognise processed foods and only a half of them read food labels at purchasing. The recognition score of processed foods, snacking moneys, and snacking frequency may be influencing factors on the reading of food labels in students. The high recognition of processed food of parents may positively affect the students' recognition, but did not affect directly the reading food labels.

The market trends of automatic meter reading associated with smart water meters were investigated. Also, recent developments and field applications of key technology for automatic meter reading associated with smart water meters were analyzed. Smart water meters have been manufactured mostly in United States and Europe and have been expanded their business to Asia. Integrated water management system combining with the additional functions such as real-time consumption metering, cost notification, water conservation, leak detection, water quality monitoring, and flow control have been operated in automatic meter reading. Both water quality and quantity data measured from smart water meters and sensors were transferred to data concentration units through neighborhood area network, and then were transferred to integrated server through wide area network. The data transfer methods were determined by comprehensively considering urban scale, density of smart water meters, power supply and network topologies. Common data collection methods such as fixed network to data concentation units, vehicles drive by, people walk by, and drone fly by have been applied. The automatic meter reading associated with smart water meters are spread throughout the world, and both water and energy savings result in saving the money and reducing the greenhouse gases emission.

Applying the S-O-R Model within an online context, a hypothesized model incorporates three review characteristics (perceived concreteness, exaggeration, and sufficient quantity of reviews) for apparel products in order to present their impact on consumer perceptions of review usefulness and consumer attitude toward and patronage intent for the online stores hosting the reviews. An online survey of Korean women (N=299) reported their experiences in purchasing apparel products online and reading apparel reviews on a regular basis. Testing of the hypothesized model showed the usefulness of reviews were determined by two review characteristics (S: perceived concreteness and sufficient quantity of reviews); however, the negative effect of exaggerated reviews were insignificant. In addition, the perceived usefulness of reviews (O-cognitive) hosted by an online store influenced online store attitude (O-affective) which subsequently led to online store patronage intent (R). This study systemically advances online retail literature by showing how the characteristics of online reviews (as a part of the online store environment) can influence attitude toward online stores and patronage intent for online stores. Long term relationships with consumers can be achieved through the building of mechanisms to enhance the perceived usefulness of reviews by employing the strategies of hosting concrete reviews and offering a sufficient quantity of reviews. This study addresses removes research gaps by testing an adapted the S-O-R Model that frames review information as an element of an online store environment using a large sample.

We live in a global village that requires a language with a genuinely global status as a means of communication. During the twentieth century, English has clearly emerged as the lingua franca owing to both past British political imperialism and the more recent superpower status of the United States. Further contributing to world domination of the English language is the fact that the computer and Internet sprang from the US. Whether you like it or not, you are destined to learn English at least to some extent in order to live in this global village. For the last two decades, one of the most mistaken ideas a number of Korean English teachers have had is that speaking and listening are the primary forms of language, while reading and writing are secondary. In fact, reading is regarded as a skill of much consequence to us since it provides us with access to a huge quantity of information on the Internet, of which at least 80% is written in English. Writing, too, deserves a great deal of attention because we are increasingly called upon to use standard English expressions. As diligent learners of English, we had better not forget the place accorded to language not only as a medium for exchange and constructing information but as a tool for thinking. So we should try to think in English to the point where we have thinking-in-English as a habit, thereby leading to increased familiarity with the language. Such familiarity entails, above all, possessing a command of English.

Corynebacterium tuberculostearicum B146, a strain derived from healthy human skin, contains a medium copy plasmid, p1B146. This plasmid was cloned and its complete nucleotide sequence determined. As a result, p1B146 was found to be 4,2 kb in size with a 53% G+C content, plus six open reading frames (ORFs) were distinguished. According to a computer-assisted alignment, two of the ORFs exhibited significant similarities to already-known common plasmid proteins, the first being the RepA gene, responsible for plasmid replication via a rolling-circle mechanism, and the second being an FtsK-like protein, the function of which remains unclear. The presence and quantity of RNA fragments in the putative ORFs were also evaluated.

The suspension of the optical pickup actuator is damped by the presence of silicone rubber damper bond at its termination. In spite of the presence of it, the actuator still exhibits a strong mechanical resonance which affects its settling time and vibrational characteristics. This resonance can cause errors in reading information from the disk, particularly in high speed CD-ROM and DVD-ROM drives. Ferrofluids are stable colloidal suspensions of sub-micron sized magnetic particles in a carrier liquid. In the actuator design, ferrofluid is applied to the surface of the magnets until the quantity is sufficient to maintain intimate contact with the bobbin/carrier assembly. The fluid is retained in the magnetic field and its viscosity provides the desired mechanical damping to the moving assembly, improving the actuators settling time and vibrational characteristics. Access time is also improved, particularly on warped or eccentric discs.
