This paper presents a comparative study on the effectiveness of teaching an engineering course using English with Specific Purpose(ESP). A study was performed using student groups; one class using ESP, and one class conducted in English with an English text. The course conducted using ESP showed the greatest improvement in English writing and conversation, and the students reported a greatly increased confidence in their ability to function professionally using English. A self-assessment of each student was conducted before and after the courses. Prior to the course less than 10% in each group felt that they are able to: a) understand a textbook, b) write an email, c) generate a project report, or d) follow a lecture given in English. The survey at the end of the course showed that the ESP teaching style resulted in significant improvements in students ability and confidence with writing and speaking in English, whereas reading skills were similar for both groups. This is due to the ESP method, in which students are required to give presentations and keep journals in English. After a brief review of the ESP principles and a discussion of how they were implemented, the background data of the participants(students) are described. Finally, the end-of-semester survey highlights the efficacy of the ESP approach.

The purpose of this study was to identify general characteristics of social lifespaces in Korean family houses and to investigate the changes in the physical aspects and room functions of social lifespaces from Yi-dynasty to the present. The documentary research method was used for this study. Total of 972 out of 1,109 floor plans were analyzed for this study. The major findings were that changes of social lifespaces from Yi-dynasty to the present have been affected by natural and socio-cultural environments. The changes in the physical aspects of social lifespaces have shown from one or two social lifespaces to various single-purpose social lifespaces such as living room, family room, drawing room, and study room. In the past, the cnetral social lifespaces, Anbang(women's quarter) was larger than the living room/Daechung(wooden floor) but the living room in the present has become a central social lifespaces and larger. The room function of Anbang has changed from multi-purpose space to private space. Living room/Daechung had used as a pathway rather than a social lifespaces in the past but the living room has played many fuctional roles of family social activities in the present. The kitchen has also begun to use as a social lifespace. This is a new symptom that kitchen and dining spaces will be included as a new social lifespaces.

The specific objectives of the study were (1) to determine the preferences for three home economics curriculum designs(HECD) categorized by Majorie Brown(Technical HECD, Self Actualization HECD, and Practical Reasoning HECD), (2) to determine the differences between middle school HE teachers and high school HE teachers on each curriculum element, and (3) to determine the relationships between preferences for three HECD by curriculum elements and personal and professional characteristics of HE teachers. For these objectives, the subjects were randomly selected from HE teachers of secondary schools in the areas of Seoul, In-Cho, and Keungi. The 300 data collected by mailed survey were analyzed into frequency, percentage, Chi-square, and contingency coefficient using SAS program. The major findings were as follows: 1) the majority of HE teacher respeondents preferred the Practical Reasoning HECD about the following curriculum elements: Purpose of HE education, knowledge, subject matter, teaching method, society and culture, learner, learning atmosphere, and HE teacher's role. 2) No significant difference emerged when Chi-square was applied to determine difference between the two groups(middle and high school HE teachers) on three HECD according to each curriculum element. 3) The contingency coefficient between preferences of HE education purpose for three curriculum designs and age was 21, years of teaching was 23, between preferences of learning atmosphere of three curriculum designs and location of school was. 17. These mean that the younger and more beginning teachers perferred HE purpose of the Practical Reasoning HECD, and HE teachers working in urban area more preferred learning atmosphere of Practical Reasoning HECD.

A special purpose machine with two manipulators and quadruped crawler system is being developed to work at disaster sites where it is intended to quickly respond in the initial stages after the event. In this study, a terrain recognition module is developed so that the above special purpose machine can quickly obtain ground information to help choose its path while recognizing objects in its way, this is intended to enhance the remote driver's limited situational awareness. Terrain recognition modules were developed for two tasks (real-time path guidance, precision terrain measurements). The real-time path guidance analyzes terrain and obstacles while moving, while the precision terrain measurement feature provides more accurate terrain information by precisely measuring the ground in front of the vehicle while stationary. In this study, an air-cooled sensor protection module was developed so that the terrain recognition module can continue its vital tasks in the event of exposure to foreign substances, including scattered dust, mist and rainfall, as well as high temperatures.

In this paper, a standardized phonological rule should be embodied for all people who want to use Hangul beyond nationality. This researcher suggested a phonological process protocol in unicode for the purpose of developing a computer system-based program as one of methods to pronounce Hangul correctly. First of all, to solve a problem of standardizing Hangul pronunciation, it is necessary to develop a phonological process system. In other words, when a mobile phone or a keyboard is used, inputted strings should be changed exactly by an automatic device made according to the phonological rule. For this, a phonological process table is the most important and unicode which digitalizes Hangul is the most effective. Therefore, the purpose of this study is to complete a phonological process table, suggest an algorithm by the table, and develop a computer program pursuing correct Hangul pronunciation. For the methodology of this study, the features of unicode was used to solve a problem of coding each syllable by phonemes after strings were inputted from the phonological process program. This study suggested a protocol that sounds of inputted strings were automatically changed via recombination using a phonological process table. The ultimate purpose of the study was to help pronounce Hangul correctly according to the pronunciation rule.
