Filipino language is an Austronesian language based on numerous native languages with influences from other major languages such as English and Spanish. The Filipino alphabet is consists of 26 English alphabets, with the addition of two letters, "$\tilde{n}$" and "ng", a total of 28 letters. Filipino language expressions and sentences are still incomparable to English and Spanish even though there are numerous borrowed words from these languages. This study aims to discover the uniqueness in the Filipino language by identifying the frequencies of the letters in common words used and be able to introduce a revolutionary keypad for the Filipinos which is scientifically efficient. To compare the efficiency of the revised and the original keypad, computations using Fitts' Law, Hick-Hyman Law and KSPC were done. Results showed that the new keypad layout was more effective than the original keypad. Introducing a improvised keypad to the Filipinos is one step closer in achieving customized services and features to Filipinos in mobile computing.

Purpose: This study was performed to analyze the visiting nurses' job using Developing a curriculum (DACUM). Methods: The DACUM committee with 6 visiting nurses participated in the workshop. In this workshop, the visiting nurses role was defined and their duties and tasks were identified. After content validation via the experts, the pilot test was conducted to 78 nurses. Results: A total of 13 duties and 82 tasks were identified on the DACUM chart which represented the importance, difficulty, and frequency of tasks with alphabet A, B, and C as its higher degree. Regarding duties, 'visiting nursing for high risk group' is the highest, while the lowest was 'public welfare events'. Regarding to tasks, 'discovering a new patient' was the highest, while 'selecting patients and offering medical supplies (nutritional supplement, patch)' was the lowest one. Conclusion: The results showed that visiting nurses working in the visiting health care service center were doing more various duties and tasks than those working according to 'Act on Long-term Care Insurance for the Aged'. The results can be used to develop training programs for visiting nurses and evaluation-scale of their job performance.

When a Japanese learner in Korea tries to find Japanese dictionary, he must know the pronunciation of the target word. But it's not easy to know the pronunciation of target word from Japanese sentence. Because most of general Japanese sentence shows only HanJa(Chinese character) instead of Kana(Japanese alphabet). If the Japanese learner knows the Korean traditional pronunciation of the target word, he can input the word to electronic Japanese dictionary with the Korean pronunciation. For this solution, the dictionary service provider must convert the Japanese word to Korean pronunciation, in advance. After setting of the conversions as a additional searching process, we can find the target word through Korean pronunciation of the Japanese HanJa, This process is possible for the three reasons below, 1. Korean, Japanese and Chinese are using the nearly same HanJa. The difference is small. 2. Most Japanese learner in Korea, knows the Korean pronunciation of the HanJa. 3. The Korean pronunciation of the HanJa is nearly unique, a HanJa has a Korean pronunciation, generally.

This paper is intended as a preliminary study on phonetic and phonological differences between Polish and Korean languages. In this paper an attempt is made to examine the most conspicious difficulties encountered by Polish learners who begin to speak Korean (and in doing so, 1 would hope that it might be of help to future learners of both languages). Since the phoneme inventory and general phonetic rules for both languages are very different, teaching and learning accurate pronunciation is extremely difficult for both the Poles and Koreans without any previous phonetic training. In the case of Polish and Korean we can see how strong and persistent the influences of the mother-tongue are on the target language. As an example I would like to discuss the basic differences between Polish and Korean consonants. The most important consonantal opposition in Polish is voice-/voicelessness (f. ex.; 〔b〕 / 〔p〕, 〔g〕 / 〔k〕) while in Korean, opposition such as voice-/voicelessness is of secondary importance. Therefore Korean speakers do not perceive the difference between Polish voiced and voiceless consonants. On the other hand, Polish speakers can not distinguish Korean lenis / fortis / aspirated consonants (f. ex.; ㅂ 〔b〕 / ㅃ 〔p〕 / ㅍ〔ph〕, ㄱ 〔g〕 / ㄲ 〔k〕 / ㅋ 〔kh〕)) opposition. The other very important factor is palatalization which is of vital importance in Polish and, because of this, Polish speakers are extremely sensitive to it. In Korean palatalization is not important phonetically and Korean speakers do not distinguish between palatalized and non-palatalized consonants. The transcription used here is based on ' The principles of the International Phonetic Association and the Korean Phonetic Alphabet ' (1981) by Hyun Bok Lee.

This study has been undertaken as a basic research for automatic pattern design for baseball uniforms manufactured under custom-MTM system, propose building up of a system whereby various partial patterns are combined under an automatic design system and develop a multi-combination type pattern searching algorithm which allows development of a various designs. As a result of this, type classification based on pattern design elements includes side, open, collar, facing and panel type. Design have been divided into coarse classification ranging from level 1 to 7 according to pattern design elements, based on a design distribution chart. Out of 7 such levels, 3 major types determining design which are, more specifically, level 1 sleeve type, level 2 open type and level 3 collar type, have been taken and combined to determine a total of 12 types to be used for design classification codes. Respective name of style and patterns have been coded using alphabet and numerals. Totally, pattern searching algorithm of multi-combination type has been developed whereby combination of patterns belonging to a specific style can be retrieved automatically once that style name is designated on the automatic pattern design system.

알파벳 ${\Sigma}$로 구성된 길이가 각각 m, n인 두 문자열 X, Y가 주어졌을 때, X, Y의 확장편집거리는 동적프로그래밍을 이용하여 O(mn) 시간과 공간을 계산할 수 있다. 최근 m개의 쓰레드를 이용하여 O(m+n) 시간과 O(mn) 공간을 사용하여 X, Y의 확장편집거리를 계산하는 병렬알고리즘이 제시되었다. 본 논문에서는 GPU의 공유메모리를 활용하여 수행시간을 개선한 병렬알고리즘을 제시한다. 실험 결과, 개선된 병렬알고리즘이 기존의 병렬알고리즘보다 약 19~25배 이상 빠른 수행시간을 보였다.

Vibrotactile feedback is widely used in designing non-visual interactions on mobile phones, such as message notification, non-visual reading, and blind use. In this work, novel vibrotactile codes are presented to implement a non-visual text reading system for mobile phones. The 26 letters of the English alphabet are formed in an index table with four rows and seven columns, and each letter is mapped using the codes of vibrations. Two kinds of vibrotactile codes are designed with the actuator's on and off states and with specific lengths (short and long) assigned to each state. To improve the efficiency of tactile perception and user satisfaction, three user experiments are conducted. The first experiment explores the maximum number of continuous vibrations and minimum vibration time of the actuator's on and off states that the human can perceive. The second experiment determines the minimum interval between continuous vibrations. The vibrotactile reading system is designed and evaluated in the third experiment according to the results of the two preceding experiments. Results show that the character reading accuracy reaches 91.7% and the character reading speed is approximately 617.8 ms. Our method has better reading efficiency and is easier to learn than the traditional Braille coding method.

본 논문은 CDMA 셀룰라 역방향 접속 시스템의 성능개선을 위하여 이중직교 신호에 대한 다중심볼 검파방식을 제안하고, 이에 대한 성능해석과 컴퓨터 모의실험을 수행한다. 이 방식은 기존의 심볼단위 비동기 검파대신 복잡도를 줄인 근사 MLSE에 의해 다중심볼로 구성된 복조 데이터와 채널을 동시에 예측한다. 이 방식은 또한 주어진 심볼의 워드수 M에 대해 관측하는 다중심볼 길이 N을 적절히 선택할 때 채널의 예측이 없이도 이상적인 동기검파 방식에 근접한 오류성능을 얻게 해준다. 특히 매우 의미 있는 사항은 이 방식을 CDMA 역방향 접속 시스템에 적용할 때 요구되는 평균 비트당 신호대 잡은 전력비 ${\gamma}_{b}$를 약 1.4dB정도 줄일 수 있어 38% 정도의 용량이 증가된다.
