Interface modules design between image sensor and external components are designed by FPGA (Field Programmable Gate Array) in this paper. Generally speaking, to satisfy synchronization for the poor quality data in image, SRAM is needed. To receive synchronization signal and image signal data with pixel dimension, the proposed interface logic technique is implemented. From the proposed technique, we can obtain more clear screen by implementing with pixel dimension. Operating frequency of image sensor and that of TFT-LCD are 50MHz and 6.5MHz, respectively. Most of control logic functions are embedded in FPGA. The designed logic gate counter has 33,216 and is designed by Quartus II.

When a insulator plate is inserted to the discharge path of a space discharge gap in which the field strength is not uniform, the spark voltage under the atmospheric pressure between the electrodes decreases or rises according to the position of the insulating plate. Also it is reported that if a metallic barrier plate is inserted to the discharge path of the same space discharge gap, similar variations of spark voltage are found. Speaking briefly, mensioned above are the spark voltage characteristics when an insulator or metallic barrier is inserted to the space discharge gap. Also some experimental results, concerning to the surface creepage flash over characteristics at the case when an insulator barrier is inserted to the discharge path of a surface creepage discharge gap, were reported by Peek. But up to now there are no reports on surface flash over voltage characteristics at the case when a metallic barrier is inserted to the surface creepage gap. In this study the effects of a conducting metallic barrier inserted to the path of a surface creepage discharge gap on the flash over voltage characteristics are investigated theoretically and experimentally, and got some important results, clearing the effects of the position and width of a conducting barrier is inserted, the surface flash over voltage characteristics appear as an Inverse N or W Characteristics. Such theoretical or experimental results may have some relation not only with the effects of dry belt and snow on suspension insulators, but also with the effects of dirty zone or water drops on the surface creepage flash over voltage.

Most of the metaheuristics are made by imitating the action of the animals. In this paper, we proposed Mine Algorithm. The Mine Algorithm is a metaheuristic that imitates the action of the human being. Speaking of search, the field in which the know-how and the heuristics of the human being are melted best is the mining industry. In the Mine Algorithm we formalize the action pattern of the human being by focusing the mine business. The Mine Algorithm uses various searching techniques fluently and shows equally good performance for broad problems. That is, it has good generality. We show the improved generality of the Mine Algorithm by the comparing experiments with the conventional metaheuristics.

NAT (Network Address Translation) is an IP address modification protocol that translates private IP addresses into authentic Internet addresses. The main features of NAT are to improve network security and to save IP addresses. Generally speaking, in order to perform its functionality. NAT uses the address informaiton in the packet header. Certain application protocols, however, use the information in the packet data as well as the imformation in the packet header to perform end-to-end communication. Therefor, to support these types of application protocols, NAT should be able to perform appropriate translation of protocol information in the packet data. In this thesis, we design and implement a method which translates virtual IP information in the packet data into real IP information by using port proxy server.

Taking the issues of inequity and power between NES and NNES teachers as a starting point, this qualitative study explores the way the widespread belief of the native speaker fallacy manifests itself in one NNES teacher's teaching life and is linked to the teacher's understanding of herself as an English teacher. Guided by critical applied linguistics (Pennycook, 2001) and using Bourdieu's (1991) theorization of symbolic violence, I conducted an instrumental case study (Stake, 1995) in an ESL writing class at a US university. I collected data through classroom observations and interviews over a nine-month period and analyzed the data using the constant comparison method (Glaser and Strauss, 1967). The findings illustrate the ways the dominant ideology of the native speaker fallacy works to maintain and reproduce the status quo unequal relation between NES and NNES teachers by making all parties involved believe in the artificial sociocultural arrangements that favor NES teachers as legitimate. The findings direct our attention to the importance of critical teacher education that will enable future TESOL professionals to engage in critical reflection on diverse issues and envision transformative change. The findings, in particular, point to the need for language support for NNES teachers in TESOL teacher education.

The aims of this study are to imvestigate the changes seen in rural kitchens and the factors affecting the modernization of agrarian kitchen space in mountain areas, and to compare them with those in the plains. The major findings are as follows. 1) The kitchen space in mountain areas remained in the state of a combined style(depicting both western and traditional styles), while the kitchen space in the plains after the 1980s showed a tendency toward the western style. Generally speaking, the physical state of kitchens in mountain farmhouses, therefore, was at a low level in comparison with that of the plains. 2) The kitchen improvement projects of Sae-Ma-Eul Movement fostered a trend toward the western and combined style kitchens in the plains, but it did exert a little influence only on a part of the four mountain areas, and it resu]led in a combination of both styles. 3) Among the socio-demographic characteristics under consideratien. only the level of education achieved by the wi fe was found to be a determinant factor of the kitchen type in the mountain areas. but the level of education achieved by the husband and the family life cycle were two determinant factors in the plains. Under the category of family life style. the factors affecting the kitchen type in the mountain areas were cooking-heating fuel and the position of the refrigerator, while the main factors in p]ains were the place and the method of eating. cooking-heating fuel, the position of refrigerator, and numbers of family-memorials.

Voice complication without the laryngeal nerve injury can occur after thyroidectomy. The purpose of this study is to investigate voice changes according to extent of thyroidectomy with acoustic analysis. Thirty-five female patients with papillary thyroid carcinoma took voice evaluation at before and 1 month, and 3 months after thyroidectomy. Acoustic analysis parameters were speaking fundamental frequency(SFF), min $F_0$, max $F_0$, dynamic range $F_0$, jitter, shimmer, noise-to-harmonic ratio(NHR), and Cepstral prominence peak(CPP). Repeated-measured analysis of variance was applied. Time-related voice changes showed significant differences in all parameters except NHR. At 1 month after surgery, voice quality was worse and pitch was decreasing, but voice quality and pitch were improving at 3-month follow-up. Voice changes according to the extent of surgery were in SFF, max $F_0$, and dynamic range $F_0$. Time by surgery-related voice change existed only in min $F_0$. The result showed that the severity of voice complication depended on the extend of thyroidectomy which had a negative impact on $F_0$-related parameters. The deterioration of voice quality at 1 month after thyroidectomy may be affected by the loss of thyroid hormone in the blood. The descent of $F_0$-related parameters may be impacted by laryngeal fixation of surgical site adhesion.

This study examines the current state of English education in private kindergartens in Korea. Among 1700 kindergarten teachers surveyed for this research, 680 replied that their institutions provided English lessons for children. Analyses of the data collected from these 680 teachers showed : 1) They started to teach English not because of educational considerations but because of pressure from children's parents or kindergarten principals; 2) Most of the English teachers were part-time instructors specially recruited for English lessons. Generally, English lessons were given two or three times a week, with one session lasting for about 20 minutes. A variety of teaching methods and materials were used for the lessons given to children aged three to five. Focus of the lessons was given to listening and speaking words and sentences; 3) Most of the teachers considered the scarcity of qualified English instructors as the most serious problem for providing English education in kindergartens, and they did not want to teach English themselves. They evaluated positively the performance and role of Korean part-time English instructors. The evaluations were generally poor as to native speakers serving as kindergarten English teachers.

This study was conducted to explore the communication processes and contents between cooperating teachers and their student teachers during student teaching conferences. To reach this purpose, five research questions were generated. 15 cooperating teachers and their 15 student teachers from 9 kindergartens located in Seoul and Ilsan city participated in the study. The conferences of each dyad were tape-recorded for further analysis. "Analyzing System for Interaction of Learning" designed by Thies-Sprinthall was used to analyze the data. The research findings were as follows: First, cooperating teachers talked more than the student teacher during the conference. Second, the cooperating teachers used more directive talk than indirective talk. Third, the speaking patterns of the student teachers revealed that student teachers express their opinions frequently(55.6% of total pattern). Fourth, cooperating teachers focused their remarks more on the instructional issues(48.5%). The cooperating teachers emphasized on the operation of class(23.1%), other subject(12.3%), practical guidance(10.7%), self-assesment(5.4%) in order. Fifth, the most emphasized issue by student teachers was the instructional matters which was reported by 53.4% of the entire subjects.
