In order to observe the effect of mandibular orthopedic repositioning appliance (MORA) on body strength, the author measured back muscle strength with Digital Back Muscle DYNAMOMETER (TAKEI KIKI KOGYO Co., Tokyo, Japan) before MORA, 15 days after and 30 days after MORA in 12 men and then analysed them statistically. The subjects were weight-lifting athletes of Seoul Athletic High School without dysfunction of masticatory system. MORA was fabricated at 1.0-1.5rnm isotonically closed position (Myocentric Occlusion Position) from mandibular rest position (Myocentric Rest Position) using Myo-monitor (MyoTronics Research Inc., Seattle, Washington, USA) and-SVT C-II (Tokyo Shizaisha Inc., Tokyo, Japan). The results were as follows : 1. The mean of back muscle strength before MORA was 150 kg, that of 15 days after MORA was 165 kg (4.43% increase than before), and that of 30 days was 175 kg (10.76% increase than before). 2. There was a significant difference among back muscle strength before MORA, 15 days after and 30 days after MORA (P<0.01: repeated measures one-way ANOVA). 3. According to the result of determining mandibular position for MORA fabrication, mandibular rest position after relaxation with Myo-monitor was 3.2mm lower, 1.0mm posterior, and 0.5 mm left from centric occlusion. And the mean of the amount of lateral deviation was 0.7 mm.

This paper investigates how focus contributes to the phonological and phonetic realization of Japanese intonation. Pierrehumbert & Beckman (1988) pointed out that textual prominence results in the H-tone peak raising on the focused item and IP (Intonational Phrase) initiation before the focused item. Similarly Kori (1989) suggested that the F0 peaks on the words after the focused item tend to be suppressed. Although they give a general description of the characteristics of focus phenomena in Japanese intonation, they fail to explain the F0 peak interaction between H phrasal tone and lexically specified pitch accent in more-than-3-mora words whose accent locations varies from early to late. In this paper, we perform the experiment to investigate the following three points. First, we would like to look at the systematic intonational differences between focused and neutral APs; specifically, focused APs, either accented or unaccented, are compared with the neutral counterparts in terms of F0 pattern. Second, we investigate F0 patterns of a focused AP with more than 3 morae, as the accent of the word varies from early to late. Since an AP with a late accent has a H- on the second mora as well as H*+L on its accent mora, it is expected that these peaks will show systematic F0 pattern when it is focused. Our third concern is F0 patterns of a post focus AP with more than 3 morae, that is, whether a post-focus word is dephrased or just downstepped as the word accent location varies from early to late. This paper is significant in that it tries to clarify the F0 peak interaction between H-and lexical pitch accent H*+L in a variety of focus contexts in Japanese intonation.

This study is to understand the types and characteristics of wool fabrics of the Korea. It classifies the types of wool fabrics whose name can be found in the documents by their weaving methods and it researches their characteristics by type, time, usage, and pattern. In Wool fabric of the ancient age were there compound weaving fabric, such as Gyesoo. which is made with embroidery method, Gyegum, which is made with embroidery in gold threads, as well as general fabric, such as plain-weaved Gal, twill-weaved Sagal, gauze-weaved Mosa, Mora, etc. There were also various weaving methods, such pile-weaved Yung, tapestry-weaved Tabdung, or Guyoo, or Dahm, felt-weaved Jeon, etc. It was found in documents that wool fabric such as Gye, Jeon, Dahm were produced in Korea and China. In case of Korea, wool fabric was enormously developed in Koguryo, Shilla, Balhai, United Shilla. Koryo era. Particularly in Koguryo and Balhai, the stock-farming and hunting were the main parts of their occupation. In Koryo era, the weaving technique of wool fabric had made great development. The wool fabric was used not only in clothing but also in official hats, rugs. wall-tapestries, etc.

This study investigates the effect of Japanese (L1) on the production of the Korean rhythmic structure. Korean and Japanese have typologically different rhythmic structure as a syllable-timed language and mora-timed language, respectively. This rhythmic difference comes from the different phonological properties of the two languages. Due to this difference, Japanese speakers that are learning Korean may produce a different rhythm than native Korean speakers' rhythm. To investigate the influence of the native language's rhythm on the target language, we conducted an acoustic analysis using acoustic metrics such as %V, VarcoV, and VarcoS. Four Korean native speakers and ten advanced Japanese Korean learners participated in a production test. The analyzed material consisted of six Korean sentences that contained various syllable structures. The results showed that KS and JS's rhythms are different in %V as well as in VarcoV. In the case of VarcoS, significant rhythmic difference was observed in the VC and CVC syllable, in which the coda segment is nasal sound. This study allowed us to observe the influence of L1 on production of L2 rhythm.

In this paper we reproduce results on $Gr{\ddot{o}}bner$ fans of ideals following a paper by T. Mora and L. Robbiano [5], and introduce stable $Gr{\ddot{o}}bner$ fans of ideals introduced by D. Mall [4]. We make minor corrections for the clarification, simplify proofs and provide new proofs. At the end we give a description of $Gr{\ddot{o}}bner$ fans of toric ideals.

The phonetic study of English language in Japan is a matter of great importance, a problem of major concern and a. vital subject The special difficulties which the Japanese college students have in learning English lie in the field of prosodic features of English, such as, syllable, rhythm, stress, intonation, prominence, of.. These difficulties have made Japanese students' pronunciation relatively monotonous or mora(ness). In my presentation, the specific phonetic features of Japanese language first will be discussed and clarified. And then the effective teaching method of intonation to improve Japanese students' pronunciation will be suggested. Finally, the oral dialogue with intonation analysis and transcription in the class room will be demonstrated to highlight the presentation.

It is well known that Japanese prosodic structure assumes mora below the syllable tier. Syllables with V or CV structure are counted as having one morn whereas those with coda consonants /-pp, -tt, -kk, -ss, -N/ or long vowels are counted as having two morns in Japanese. This study measured the acoustic duration of these special moras ('tokusyuhaku') produced by Tokyo dialect speakers to see if they are isochronic with V or CV. It also examined the production of Korean(Seoul/Kyungsang dialect) and Chinese native speakers loaming Japanese as a second language to examine how the learners' first language influence their second language. Finally, it examined how speakers of the Akita dialect, which is blown as a syllabeme dialect in Japanese, produced them. The results showed that intra-speaker variation as well as inter-speaker variation was observed in the production by Akita dialect speakers. Production of native speakers of Chinese and Kyungsang dialect of Korean -- which have vowel length contrast in their phonological systems -- showed a similar result to Tokyo dialect speakers, which implies the influence of the learners' first language on the acquisition of the second language.

It is very important to secure the marine vessels during entire loading and off-loading operations. The environment influences on loading conditions. the western coastal area of Korea is characterized as a strong current due to a high tidal range. The tension of mooring lines varies as per the current and wave changing its magnitude during the day. A proper mooring arrangement and design of mooring line should be determined as per environment conditions. In this study, a 50,000 DWT container ship being moored is investigated numerically. The dynamic tension of mooring lines is estimated by MORA (Mooring Response Analysis) software. Environmental conditions of selected offshore terminal site are plugged as input data. The mooring line tensions are obtained for various wave frequencies per wave directions. The results demonstrate the change of tensions of lines and the allowable range of safe conditions in berthed mooring.
