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.

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.

Purpose: The purpose of this study was to investigate the effect of whole-body vibration training on the flexibility and agility of professional soccer players. Methods: Sixteen professional soccer players participated voluntarily in the study. Subjects were allocated to two groups: the experimental group received whole-body vibration (WBV) and team training, and the control group received only team training. Team training was conducted in 15 sessions of 70 min duration over 3 weeks. WBV training was applied at 40 Hz frequency, 5 sets (1 min-training, 1 min-resting) in a squatting position. Outcomes from sit-and-reach, side-step test, burpee test, and T-test were measured before and after training. To examine pre- and post-intervention differences between the two groups, a paired t-test was used. Independent t-tests were performed to compare pre- and post-test scores and the time difference of the two groups. Results: Significant improvements in sit-and-reach and agility variables were observed in the experimental group (p < 0.05). In particular, flexibility (sit-and-reach) and agility (the side-step test and the burpee test) were significantly different between the two groups (p < 0.05). Conclusion: These findings suggest that whole-body vibration training has a positive effect on performance enhancement for professional soccer players.

상태당 가지 수를 가변시킨 ARHMM을 이용한 화자적응

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%.

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.

첨성대 수치와 역할에 대한 연구

Chumsungdae is an ancient astronomical observatory whose main role was doing 'chunmoon'. It was administrate by a royal advisory agency on state affairs. The observers observed the heaven on the observatory platform, recorded peculiar events, and watched and interpreted the signs displayed in the heaven. Chumsungdae is an stonemasonry which represents almanac principles with its peculiar shapes and the numbers of strata and stones. The numbers were thoroughly invented to match exactly the almanac constants. Chumsungdae is comprised largely of three main parts, namely the square base, the stratified cylindrical body, and the top #-shaped stonework, and the total number of stones is 404. The number of the strata (27) and the height of the cylindrical body (27 尺) stand for the days in a sidereal month (27.3 days), which implies that the motion of the Moon with respect to the stars was given more priority than to the Sun at that time of geocentricism. And the cylindrical body was thoroughly designed to consist of 365 stones, which is of course the number of days in a solar year. In addition, there are 12 strata each under and above the south entrance and this in sum makes the 24 divisions of the year. Also there is 182 stones below the 13th stratum and this represents the number of days in the winter ~ summer solstice period, and the rest 183 stones the vice versa. The #-shaped top stonework was aligned in such a way that one of the diagonals points the direction of sunrise on the winter solstice. The square base also layed with the same manner. The south entrance was built 16 degrees SE, and the upright direction of the right pillar stone coincides with the meridian circle. This was a kind of built-in standard meridian circle facilitating the observations. In a symbolic sense, Chumsungdae was thought as the tunnel reaching the heaven, where the observers wished to be enlightened with the signs and inspirations in need. With the craftsmanship and skill, the builder reinforced the stratified cylindrical body with two sets of #-shaped beam stones, piercing at a right angle at 19th ~ 20th and 25th ~ 26th strata. Likewise, by placing the double #-shaped stonework with 8 beam stones on the platform of the observatory, both the stability of the stonemasonry and a guard rail for the nightly observers were securely provided.
