According to recent trends of ubiquitous learning with the advent of smart devices, this study was to suggest for the successful achievement of "Smart Campus" initiatives by experiencing an instruction with smart-pads (tablet PCs) in a university. A pilot project was conducted as a part of building a Smart Campus in S university in Gyeong-gi Province in Korea for the study. The class was held in the Summer semester in 2011 with six participants. Using research methodologies such as semi-structured interviews and stimulated recall, perceived academic performances, satisfaction, and the usability of smart-pads were analysed. Main results included high perceived academic performances, satisfaction, and the usability, however, some negative responses also detected on the variables. Based on the results, it was suggested that specific instructional strategies should be developed in terms of hardware, software and humanware.

The purpose of this study is to investigate how the different types of reading instruction programs and reading methods influenced the creative ability and the self-directed learning ability, They were divided into two groups. Class A was taught to use 'The Author-Reader-Inquirer Cycle'. which concentrated on the writing-centered reading program model. Class B was taught to use 'The Literature Circles'. which concentrated on the speaking and listening-centered reading program model. After reading instruction. the creative ability and the self-directed learning ability increased. The writing-centered reading instruction was more effective than the speaking and listening-centered reading instruction. The reading instruction during the long-period was more effective than that during the short-period. The 'intensive reading' among the reading methods had a significant influence on the creative ability and the self-directed learning ability.

What is the relationship between the power of mask and the popularity of 'Umakdaejang(which means a band master in Korean)' who was one of the mask-singers in King of Masksinger? And which aspects of the contemporary Korean society were projected to this fever of Umakdaejang? This study has made efforts to answer these questions. To do this, it has examined the episodes that Umakdaejang appeared in the TV program King of Masksinger, has dealt with the origin and purpose of mask, and with the cultural meaning of the mask's concealing and revealing identity in order to understand the power of mask. Findings are as follows. Umakdaejang amplified the curiosity of his identity by displaying anonymous typicality with the mask. He also showed the resistant gestures against the forms and manners of the existing TV music programs through the way of somewhat tough, uncontrolled, and mischievous behaviors. By doing so, he exposed the desire of self-revelation. As a result, by means of its anonymity and resistance, the mask functioned as an effective apparatus being able to resist against the class polarization of the capitalist ideology. This can be viewed as the origin of the fever of Umakdaejang as well as the very power of mask itself.

By comparing and evaluating the neutron dose when running cyclotron in fixed type measuring machine and portable type measuring machine, we performed this study to see if there is any difference between the doses in both measuring devices. We performed correction 3 times for the portable type during the experiment. We measured the values 12 times for each correction, so total 36 times by using the fixed type and portable type once every 2 weeks from June 2012 to February 2014. The statistics for the portable type and fixed type for each experiment showed 0.186, 0.511, and 0.057, which are not statistically significant. Therefore, we have come to the conclusion that unless there is deviation based on the correction period of the portable type, correction of fixed type wouldn't be necessary. Also, reduction of social costs may be achieved if we install an alarm meter, which is relatively low priced compared to the high cost neutron measuring machine, when detecting higher level than the interested standard level.

This paper examines the way that the principles of coloration for Hoecha(繪次) and Sucha(繡次) were applied for shoe making in ancient China and Korea. Hoecha is the principle of drawing, and Sucha is the principle of embroidery. Hoecha and Sucha is the application principle of the five colors(五方色) from the five elements(五行: metal, wood, water, fire, and earth). Hoecha matchs a color with the opposite side color, and Sucha matchs a color with the beside color. A shoe consists of Sinul(body of shoe) and ornaments attached to it. According to the ratings of shoes, Hoecha and Sucha were differently applied for coloration of Sinul and its ornaments. In general, shoes were classified into Seok and Gu. For Seok, which was the high-ranked shoes, Hoecha was applied, while Sucha was applied to Gu, the low ranked shoe. As Hoecha was originally a principle of coloration for patterns on tops(jacket. 上衣), it was applied to the high ranked shoes i.e., Seok. Also, as Sucha was a principle of coloration for patterns on bottoms(skirt. 下裳), it was applied to the low ranked shoes i.e., Gu. Thus, black was decorated on red Seok, blue on white Seok, red on black Seok, yellow on hyeon(玄: a kind of black color) Seok, and white on blue Seok, all of which were applications of the principle of Hoecha. As the application of the principle of Hoecha to Seok was also done for red Seok for males and females in late Joseon, and red Seok for the crown prince in the period of the Korean Empire, black decorations were used for red Sinul. However, for blue Seok, worn by females in the period of the Korean Empire where Ming's systems prevailed, black decorations were used, which was an application of Sucha. Though there had been no discrimination between genders in the application of Hoecha and Sucha originally, the low ranked principle of coloration was applied to Seok for females.

The goal of this study is to look deeper into a reading education method for improving cognitive abilities of petty officer majoring students in community college level. Lack of the cognitive ability through the passing status of reading information processing highly can cause a problem for understanding information of context. Therefore, this study redefines the reading step to improve the cognitive ability. also, it sets up progress steps; material selection - learning - inspection - practice based on the cognitive abilities. To achieve those goals, there are two major ways. The first, setting up a proper reading assignment that is suitable for petty officer major students in community college level is a key step for this study. Second, the instructor leads the students to judge their own cognitive ability objectively by using a portfolio curriculum which contains a checking list of the portfolio, structuring a curriculum based on weekly achievements, self-checking, and setting up a direction of practice. The two presented ways are the most effective ways to develop students' cognitive ability based on continuous reading and checking. For the last, the study mentions a proposal for further tasks in this field of the study.

In the urban and rural complex, taxis move from downtown to rural areas for business purposes, and operate a combined surcharge system that preserves losses when they back to downtown. However, complaints related to the abolition of the compound surcharge system are increasing due to deformed operation that does not fit the purpose of the system. When the combinedsurcharge system is abolished, the taxi industry can be hit hard by the decrease in profits, and local governments are inevitable to support it. However, it is difficult to set the size of the subsidy considering the decrease of actual income. This study is to estimate the income reduction in the abolition of the combined surcharge system by scientific and objective method by analyzing the DTG data and the sales data collected from the digital driving recorder installed in the corporate taxi of the urban and rural complex area (e.g., Tongyeong city). This study is meaningful in that it used DTG data to solve the current issues in the real region and suggested the use of new DTG data.
