In high-capacity disk drives with ever-growing track density, the allowable level of position error signal (PES) is becoming smaller and smaller. In order to achieve the high TPI disk drive, it is necessary to improve the writing accuracy during the STW(servo track writing) process through the reduction of TMR sources. Among the main contributors of the NRRO(Non-Repeatable Run-out) PES, the disk vibration and the HSA(head-stack assembly) vibration is considered to be one of the most significant factors. Also the most contributors of RRO(Repeatable Run- out) come from the contributors of NRRO which is written-in at the time of STW(servo track writing) process. In this paper, the experimental test result shows that the effect of NRRO on servo written-in RRO effectively can be reduced through a STW process under low dense medium condition such as semi-vacuum.

In this study, I analyzed what rhetorical citation type students most frequently used when reinforcing logic of their opinions and arguments in research papers, and compared these rhetorical types between higher and lower Korean proficiency levels of students. These 30 student papers included the following rhetorical citation types: statistics, attribution, exemplification, statement of use, establishing connections between sources, and comparing one's own findings or interpretations with other sources. Statistics was the most frequently used rhetorical citation type. In addition, the group with the highest level of Korean proficiency used citations about 8 to 11 times in their papers, and incorporated a variety of citation types including attribution, statistics, exemplification, and statement of use. Lower level students used significantly less citations and citation types. Therefore, it is necessary to raise awareness that "citations" is an important strategy to reinforce one's own logic, teach various types of citations as important research writing strategies, and prepare a more citation-focused academic writing curriculum.

The aim of this study was to explore the use of Google Classroom as a learning management system for College English. The study targeted 34 university students. They took part in various activities, such as writing reactions to video lectures, peer-editing essays, and recording video presentations, et cetera. For the study, a t-test was conducted to evaluate the English development of the students. The two essays that each student wrote were used as the data sources. The result (t=-5.854, p=.000) indicated an improvement in their English writing proficiency. In addition, a survey was conducted to gather students' feedback regarding their perceptions towards the course. The study covered five aspects of their experience: Google Classroom, language development, Quizlet, classroom experience, and essay-writing experience. From the results, students indicated a positive response to the program. The use of Google Classroom in an online learning setting accomplishes two things; it helped the students in the development of their English proficiency, and provided activities that students find interesting, which in turn stimulates their self-learning spirit.

For a long time, traditional culture has been regarded as one of the sources of the inspiration, method and language of Chinese writing. In this article, we studied the medium- and long-term impact of a traditional Chinese culture seminar attended by college students on the output of creative writing. The seminar included traditional Chinese philosophy, history, literature, art, etc. It spanned three years (22 months) and held lectures lasting for approximately two hours once a week. The subjects of the prospective cohort study included 130 first-year college students who participated in the seminar and 130 controls. From September 2016 to June 2018, 72 lectures were held. We measured the creative writing output from the first lecture (September 2016) to December 2021 (64 months in total), including novels, essays, poems, and plays. Two indicators, the total number of words (TNW) and the quality of yield (QY), were evaluated by a 15-member panel. Although the TNW and QY of the participants and their controls were similar before the seminar, we found that the participants have higher TNW and QY than the controls after participating in the seminar. The difference in TNW became significant after month 51 (p<0.05), and the difference in QY became significant after month 46 (p<0.05). After these dates, the differences stabilized. In addition, text analysis indicates that by month 64, traditional cultural elements in the works of the participating group had a higher frequency (p<0.001). The research shows that the traditional culture seminar not only enhanced the yield of college students' creative writing but also improved the quality of their work. The traditional cultural elements enriched the works of the seminar participants.

This paper investigates the difference of writing requirements between the UCC2. and the UN convention on international sales of goods (CISG). To do it, the U.S writing requirement by statute of frauds was introduced by two sources of laws including common law and UCC${\S}$2-201. Although the U.S. statute of frauds requires some contract to be written with formalities, the way the requirement is satisfied is quite flexible in terms of its formalities. The UCC is more flexible than the common law in its formalities. The CISG does not require the sales contract to be written with any format, which is totally different from the U.S statue of frauds. Such differences between the U.S laws and CISG in writing requirement were investigated in the context of conflicts of laws.

The purpose of this study was to investigate children's(K-5) conceptions about light in Korea. The two aspect of children's conceptions about light were identified : the sources of light, the nature of vision. Data were collected from 92 children by a mixture of writing, drawing and interview, and were analysed by systematic networks. The major findings of this study were as follows : 1. Children showed an awareness of a wide variety of sources of light. The predominant sources exampled by children were primary sources. 2. Children explained vision as intentional activity of seeing Seeing. means action that move their heal or eyes to the objects. Infants(K-1) did not recognize that light are needed for vision. 3. A notable features in children's conceptions about light were context-dependent.

This paper deals with a part-specific analysis of grammatical errors in the production of the English passive in writing. The purpose of the study is dual: to explore common error types in forming the passive; and to provide plausible sources of the errors, with special attention to the role of the native language. To this end, this study obtained a large amount of data from Korean EFL university students using an essay writing task. The results show that in forming the passive sentence, errors were made in various ways and that the most common problem was the formation of the be-auxiliary, in particular, the proper use of tense and S-V agreement. Another important finding was that the global errors found in this study were not necessarily those with the greatest frequency. Also corroborated was the general claim that many factors work together to account for errors. In many cases, interlingual and intralingual factors were shown to interact with each other to explain the passive errors made by Korean students. On the basis of the results, suggestions are made for effective and well-formed use of the passive sentence.

This study was designed to compare mothers' beliefs of literacy development and home literacy environment and to explore how the children interacted with their mother during literacy activities and how they used the strategies to develop knowledge of literacy. The qualitative data was collected from multiple sources of naturalistic information and analyzed through triangulation of diverse methods including participant observations in the home, parental during literacy events, written logs kept by the mothers, the children's writing products, three emergent assessment forms, and photographs. The three preschoolers and their mothers provided different literacy experiences to support their children's emerging conventional literacy development. Child 1's mother highly valued the rich home literacy environment and the child 1's initiative interactions during literacy events. Child 3's home literacy context was very similar to her Montessori classroom's phonic approach and writing skills. Child 2 was provided with an inappropriate literacy environment at home through direct instruction and an emphasis on correct writing. All of the children were interested and attended to story. Child 1 interacted with her mother in expanded cycles as child's initiation, mother's clarification, and child's evaluation, compared with the child 2's simple cycle and the child 3's classroom-like cycle as mother's initiation, child's response, and mother's evaluation. The children and their mothers employed a number of diverse strategies to understand knowledge of literacy. Importantly parent education needs to emphasize the importance of playful one to one mother-child interaction, a functional holistic literacy environment., and strategies for expanding child's knowledge with parent as mediator.
