This paper presents an automated English scoring system designed to help non-native speakers of English, Korean-speaking learners in particular. The system is developed to help the 3rd grade students in junior high school improve their English grammar skills. Without human's efforts, the system identifies grammar errors in English sentences, provides feedback on the detected errors, and scores the sentences. Detecting grammar errors in the system requires implementing a special type of rules in addition to the rules to parse grammatical sentences. Error production rules are implemented to analyze ungrammatical sentences and recognize syntactic errors. The rules are collected from the junior high school textbooks and real student test data. By firing those rules, the errors are detected followed by setting corresponding error flags, and the system continues the parsing process without a failure. As the final step of the process, the system scores the student sentences based on the errors detected. The system is evaluated with real English test data produced by the students and the answers provided by human teachers.

Recently, YouTube's growth started drawing attention. YouTube is not only a content-consumption channel but also provides a space for consumers to express their intention. Consumers share their opinions on YouTube through comments. The study focuses on the text of global entrepreneurs' speeches and the comments in response to those speeches on YouTube. A content analysis was conducted for each speech and comment using the text mining software Leximancer. We analyzed the theme of each entrepreneurial speech and derived topics related to the propensity and characteristics of individual entrepreneurs. In the comments, we found the theme of money, work and need to be common regardless of the content of each speech. Talking into account the different lengths of text, we additionally performed a Prominence Index analysis. We derived time, future, better, best, change, life, business, and need as common keywords for speech contents and viewer comments. Users who watched an entrepreneur's speech on YouTube responded equally to the topics of life, time, future, customer needs, and positive change.

A distinctive difference of hydrocarbon in crude oil and petroleum products exists. Depending on the origin where it comes from, crude oil shows its own unique pattern which is different from petroleum products containing characteristics according to their operating process and production period. A process of mixing behavior in a tank containing residual amounts of oil draws its own pattern when analysis is conducted. The analytical process described above is named oil fingerprint method. This study investigates an effectiveness of the method for comparing data sets produced by conventional gas chromatography with mass spectrometer (GC/MS) and comprehensive two-dimensional gas chromatography (GC X GC) which is known as powerful new technology for chemical analysis.

In this study, we have assessed the fire risk of Buddhist temples located in Youngdong area by means of fire loads of components. First, we categorized the components into Buddhist temples (Dae-Ung-Jeon, Pal-Sang-Jeon), Sam-Seong-Gak (Chil-Seong-Gak, San-Sin-Gak), a Buddhist temple dormitory (Sim-Geom-Dang, Seol-Seon-Dang), Lu, Il-Ju-Mun and then carried out a field survey. Then, we examined the area of each room, types as well as quantity and dimension of combustibles. The fire loads calculated in this way were 446.96 $kg/m^2$ for Buddhist temples, 331.71 $kg/m^2$ for Sam-Seong-Gak, 164.14 $kg/m^2$ for the Buddhist temple dormitory, 463.91 $kg/m^2$ for Lu and 1042.14 $kg/m^2$ for Il-Ju-Mun, thus showing Il-Ju-Mun with the biggest fire load. We speculate that this is because construction materials were similar in size and quantity to others albeit the area of Il-Ju-Mun is smallest.

The Moon government, launched in May 2017, regards telecommunication service as part of people's welfare and is trying to save telecommunication costs. However, the direction of policy presented is assessed as symptomatic approach. This is largely attributable to the a partial improvement approach from the framework of the present mobile telecommunication industry. However if we restart from an essential point of view, the result is likely to be much better. The nation's mobile communication costs are not adequate because the government's role was not sufficient. There is a problem with the mobile phone supply chain, the subsidy payment mechanism, and the billing system. Addressing these complex issues requires the establishment of an independent system of handset distribution from telecommunication companies, ban on discriminative subsidies payment, and adoption of volume rate system. Telecommunications Business Act that defines the service charges to normalize the market might be somewhat useful, but the normal application of the Fair Trade Act is more important.

How do Korean people recognize major welfare policies of the Moon Jae-in government? Using a survey of 1,000 adults conducted in December 2018, this study examines what the public thinks about major issues related to welfare policies and what factors are related to variations in their opinions regarding the welfare policies. Results show that the public recognized the roles of government in providing welfare in a positive way. The positive opinion on expanding the coverage of National Health Insurance was the highest. Regarding the resolutions of fiscal problems of the National Pension Plan, there were substantial oppositions to reforms such as insurance premium increase, benefits cut, and increase in the age of receipt of pension benefits. Both efficiency and equality were perceived as important when government makes decision for allocating budgets. Only one-third of respondents agreed Korean government contributed to promoting the happiness of Korean people. Based on these findings, implications for developing welfare policies were discussed.

Feeding Habits of Acanthogobius flavimanus collected from the eelgrass bed in Kwangyang Bay from January to December 1994 were studied. A. flavimanus was a carnivore which consumed mainly polychaetes, crabs, shrimps, gammarid amphipods and fishes. Its diets included small quantities of ophiuroids, gastropods, bivalves, caprellid amphipods, isopods and tanaids. It showed ontogenetic changes in feeding habits. Small individuals fed mainly on polychaetes and amphipods. While the consumption of polychaetes and amphipods decreased with increasing fish sin, the consumption of shrimps, crabs and fishes increased. A. flavimanus fed diverse prey organisms in adult stage. The relative proportion of the major prey items changed with season. Although the consumption of polychaetes, shrimps and gammarid amphipods was relatively high in spring and autumn, A. flavimanus fed various prey organisms in nearly equal proportions in the other seasons.

The concept of self efficacy, originally theorized by Bandura, has been applied to a wide variety of fields including education, psychology, and business. There has been steady effort to develop relevant scales to operationalize and measure self efficacy. This article reports on the results from an analysis of Kurbanoglu's ILSES (Information Literacy Self-Efficacy Scale), the only reported such scale in the area of information literacy. Over 400 university students responded to the ILSES survey consisting of 40 items grouped in six categories. The main analysis used was factor analysis. The results show high degree of internal consistency of the items included. However, the factors derived from the study differ significantly from the factors in the original study. Overall, these factors seem to reflect the heuristic nature of students' information seeking and use patterns, favoring Internet resources and instant gratification.

This study was conducted to evaluate the dose of the space to the controller located within the mammography room conducted a research on ways to the reduction exposure to the radiation workers. Results, the dose of 6.18 mGy/year was measured when there is no difference in the hilar area of the controller position, the dose of 2.35E-11 mGy/year was measured when installing the Shielding door. In addition, when the direction of the X-ray tube anode be heading this direction controller, low average level measured was 0.30 mGy/year. Based on this study, the mammography should be considered when installing the anode and cathod directions. And, by installing the shielding door, it must be able to completely separate shooting space and control room. This is the best way radiation protection method in radiation workers.
