It is made the speaker adaptation model by adjusting both the mean and the variance of the Gaussian state observation densities of a CDHMM to use the MAPE method. However, we can't use the MAPE method in ARHMM because the components of LPC vector are used as the feature vector of ARHMM. Therefore, in this paper, we propose a speaker adaption method of ARHMM to adapt the speaker adaptation model having one branch in each state after it is divided the input utterance, which is spoken to an adapted speaker, into states by Viterbi algorithm and then make a typical vector using modified k-means algorithm. In addition we have experimented another method in which each state is represented by several branches. If the training data is insufficient, this method is not proper to train. So we vary the number of branch in proportion to the number of frame stayed in each state, and make to absorb the characteristics of speaker's pronunciation speed and duration by using the distribution of the state duration adapted to the speaker. When testing 15-word Korean domestic name isolated word model, using the proposed method, the recognition performance was found to reduce the error rate of speaker-independent systems more than 50%.

本硏究は、約束の取り消しについての返信メ-ルの談話ストラテジ-と言語表現行爲の樣相による日本語のメ-ルの特徵及び男女別の言語行動について調べたものである。まず、開始部の場合、男子學生は約束の取り消しについて<巖き>に目的を置いている一方で、女子學生は<安心>させることによって相手の負擔を緩和させようとするストラテジ-を主に表している。卽ち、女子學生のほうが人間關係の維持のために積極的な態度を見せていると言えるだろう。 續いて、內容部の場合は、慰め行爲に注目してみると、男子學生は<激勵>だけを使用するのに對し、女子學生は<共感>と<激勵>が複合した形態を使用して積極的に慰めを表明していた。最後に、儀禮的な言語行爲をもって話を終えようとする終結部においては、男子學生が情報傳達に目的を置いて終わろうとするのに對し、女子學生は<提案>によって繼續的な關係維持を希望していることを强くアピ-ルする言語行動で終結しようとしていることがわかった。これによって、男子學生は全般的な性向において、返事に目的を置いたメ-ル形式を主に取っており、また、女子學生の場合は一貫して繼續的な關係維持を望む言語行動を取っていることが分かった。 This study examines the characteristics of Japanese letter conversation and language behavior aspects of men and women through the conversation strategies of replies(mail) and language expression aspects on the cancellation of promises. First, while a male student aims to agree to the cancellation of a promise in the opening part, a female student mainly reveals a strategy to ease the other party’s burden, and maintain human relations by setting a person at ease. Second, a male student actively expresses consolation with only encouragement, but a female student does so using the mixed type of sympathy and encouragement from the consolation standpoint in the details part. Lastly, a males student finishes with a purpose of information delivery in the closing part ending with phatic verbal acts. However, a female student closes with verbal acts strongly appealing the retention of continuous relations through a suggestion. As a result, this study reveals a male student mainly takes a letter type aiming at replying, but a female student takes verbal acts hoping to continuously maintain relations.

Asphalt overlay resurfacing techniques have been widely utilized in maintaining asphalt concrete in Korea, causing severe traffic congestions while being in construction and difference in level due to the repeated overlay. Besides on these technical difficulties, there have been financial disadvantages associated with technique, mainly because overlay method has been executed for pavements with intact foundations, which is contrary to the norm. This study is aiming to increase the expected life length of the asphalt pavement up to the endurance period, to raise the efficiency of the pavement by maximizing the social benefit and to enhance public character of the street through combining ceramics with epoxy resins, which has advantages in compatibility with the existing pavement materials, durability to abrasion and endurance. It has been expected that the adoption of new method and pavement materials to the actual work sites will develop the performance of the pavements, and to lengthen the durability of the existing materials. The other advantages of the `thin surfacing` method could be the improved adhesiveness, waterproof, corrosion-proof and bending strength.

암각화 동심원 상형의 조명

Cup and ring marks are a form of prehistoric art which occurs as a petroglyph and yet we have not found any convincing interpretations for them. Finding a singular meaning which penetrates into the numerous concentric circles and their variations all over the world is a task we are generally looking for but this in practice faces a serious shortage. In this study a method of interpretations which hires dual meanings is applied. This presupposes that a concentric circle bears two meanings; it stands, on the one hand, for a spring or a well, and on the other hand, for a big star. Considering the fact that concentric circles were used as a ritual language and these should be decoded according to the `context` reflected in the relics, this method seems to interpret them better with stars than water. It is hoped that with enough accumulations of the samples this trend would again be tested in the future.

콘크리트 구조물의 성능저하, 노후화 및 용도 변경 등으로 구조물을 해체할 경우가 증가하면서 발생되는 폐콘크리트량이 급증하고 있는 추세이지만, 거의 대부분이 단순 매립용 재료로 사용되고 있다. 우리나라와 같이 부존자원이 부족한 나라에서 폐기되는 콘크리트를 포장 콘크리트용 골재로 재활용할 경우 콘크리트용 천연골재의 부족 현상 극본, 자원절약 및 환경보존 등에 크게 기여할 것으로 기대된다. 본 연구에서는 실제 구조물에 사용된 콘크리트를 해체하면서 발생한 폐콘크리트를 파쇄하여 제조한 재생골재의 혼합율을 각각 5단계로 변화시켜 제조한 재생 골재를 포장 콘크리트용 골재로 활용하기 위하여 실시한 실험결과에 대하여 고찰하였다. Amount of demolished concretes is highly produced as dismantlement of structures to increased owing to usage alteration and deteriorated of concrete structures, but most of them have been used as material for simple reclamation. Therefore, if demolished concrete could be recycled as aggregate for concrete. it will contribute to solve the exhaustion of nature aggregate, in terms of saving resources and protecting environment, especially being want of resources in Korea. In this study it was investigated into experimental results that were carried out demolished concrete recycled aggregate gained from dismantled real structures and source concrete recycled aggregate produced according to respectively 5 steps of replacement ratio for recycling as pavement concrete aggregate.

폐광산주변 토양의 환경영향해석을 위한 수학적 접근

폐광산 인근의 토양과 광미에서 발생하는 오염원은 중금속과 강산성의 배수가 주요한 원인물질이다. 이러한 오염원들은 인근의 토양까지 오염이 확산되어 결국 사람에게 건강상 유해성을 나타낸다. 본 연구에서는 중금속 오염이 심각한 폐광산을 대상으로 이들의 관리를 최적화하기 위해 요구되는 중금속 오염수준예측을 위한 수학적 접근방법을 시도하였다. 이를 위해 폐광산으로부터의 거리와, pH 및 산화환원전위(ORP)의 경시변화를 조사하여 이들의 상관성을 방정식으로 도출하였다. 대상으로 한 폐광산에 따라 다소의 차이는 보였으나, 60일간의 실험기간동안 변화되는 pH와 ORP는 초기의 pH와 ORP를 기준으로 할 때, 변화율이 0.95~1.03의 범위로 나타났다. 이것은 초기의 pH와 ORP를 기초로 폐광산 인근의 토양에서 발생하는 중금속류의 용출정도를 예측하여 환경영향평가를 실시할 수 있음을 시사하며, 이러한 접근방법은 다른 폐광산에도 적용할 수 있으므로 제거 또는 제어 대상인 중금속류의 관리에 유용하게 사용될 것으로 기대한다. The main reason of the pollution caused by soils and tailings located at discussed mines is heavy metals and AMD(acid mine drainage). Human health is affected by these pollutants which are spreaded from the abandoned mines. In this study, we try a mathematical approach to predict the pollution level of heavy metals caused by the surrounding soils of abandoned mines. The new approach is established with the correlation between the distance and pH, ORP. The change of pH and ORP can be described by the rate of initial values to experimental values. We demonstrate a realistic possibility of the mathematical approach to assess an environmental impact from disused mines cause the rate range is 0.95 to 1.03 for 60 days. Therefore our proposed approach will be useful as a few promising method for the management of heavy metals in many mines.
