  • 터널의 차수그라우팅 효과를 확인하기 위하여 영천댐 도수터널 건설공사 중에 현장 그라우팅 시험을 수행하였다. 시험은 그라우팅 시기에 따라 굴착전, 굴착후 및 콘크리트 라이닝일 설치된 이후의 압밀 그라우팅 등으로 구분하였고, 주입재료, 암종 및 지질인자, 그라우팅공의 천공방향 및 주입단계에 따른 효과를 비교하도록 계획하였다. 재료의 특성에 따른 차수효과는 포틀랜드시멘트, 마이크로시멘트, 마이크로시멘트 마이크로시멘트+규산에 비해 우레탄이 가장 뛰어났으며, 시공시기에 따라서는 라이닝후 및 굴착후에 비해 굴착전 그라우팅시 차수효과가 뛰어났다. 암종에 따라서는 화산암 및 화강암지반에 비해 퇴적암지반에서 차수효과가 낮게 나타났는데 이는 퇴적암에 발달하는 절리틈새가 적고 절리 충전물이 많아서 주입재의 침투성 저조에 기인한 것으로 사료된다. RMR값과는 직접적인 상관성이 없으나 RMR 요소 중 절리틈의 간극이 클수록 차수효과가 높게 나타났다. 천공방향은 차수효과에 영향을 미치지 않았으나 주입방법은 천공 및 주입의 단계를 세분할 수록 높은 차수 효과를 기대할 수 있다.

  • This paper studies the relation between canonical/variegated babble (CB/VB) and early speech in an infant acquiring Mandarin Chinese from 9 to 17 months. The infant was audio-and video-taped in her home almost every week. The data analyzed here come from 1,621 utterances extracted from 23 sessions ranging from 30 minutes to one hour, from age 00:09;07 to 01:05;27. The data was digitized, and segments from 23 sessions were transcribed in narrow IPA and coded for analysis. Babble was coded from age 00:09;07 to 01:00;00, and words were coded from 01:00;00 to 01:05;27, proto-words appeared at 11 months, and some babble was still present after 01:10;00. 3821 segments were counted in CB/VB utterances, plus the segments found in 899 word tokens. The data transcription was completed and checked by the author and was rechecked by two other researchers who majored in Chinese phonetics in order to ensure the reliability, we reached an agreement of 95.65%. Mandarin Chinese is phonetically very rich in consonants, especially affricates: it has aspirated and unaspirated stops in labial, alveolar, and velar places of articulation; affricates and fricatives in alveolar, retroflex, and palatal places; /f/; labial, alveolar, and velar nasals; a lateral;[h]; and labiovelar and palatal glides. In the child's pre-speech phonetic repertoire, 7 different consonants and 10 vowels were transcribed at 00:09;07. By 00:10;16, the number of phones was more than doubled (17 consonants, 25 vowels), but the rate of increase slowed after 11 months of age. The phones from babbling remained active throughout the child's early and subsequent speech. The rank order of the occurrence of the major class types for both CB and early speech was: stops, approximants, nasals, affricates, fricatives and lateral. As expected, unaspirated stops outnumbered aspirated stops, and front stops and nasals were more frequent than back sounds in both types of utterances. The fact that affricates outnumbered fricatives in the child's late babble indicates the pre-speech influence of the ambient language. The analysis of the data also showed that: 1) the phonetic characteristics of CB/VB and early meaningful speech are extremely similar. The similarities of CB/VB and speech prove that the two are deeply related; 2) The infant has demonstrated similar preferences for certain types of sounds in the two stages; 3) The infant's babbling was patterned at segmental level, and this regularity was similarly evident in the early speech of children. The three types being coronal plus front vowel; labial plus central and dorsal plus back vowel exhibited much overlap in the phonetic forms of CB/ VB and early speech. So the child's CB/ VB at this stage already shared the basic architecture, composition and representation of early speech. The evidence of similarity between CB/VB and early speech leaves no doubt that phones present in CB/VB are indeed precursors to early speech.

  • 사설시조에서는 남성화자가 여성 님에 대한 그리움과 연모의 정을 토로하는 작품들이 급증하고 이 현상은 잡가에서 극대화된다. 이런 텍스트들은 근대 이후의 시에서 '여성예찬' 혹은 '여성의 초점화'와 같은 주제가 활성화되는 내적 토대가 되며 여성에 대한 당대의 시각변화를 반영하고 있어 사설시조가 내포하는 '근대성'을 규명하는 중요한 단서가 된다. '님'에 대한 애정을 노래한 사설시조는 애정의 성격에 따라 '상사형'과 '육정형'으로 나뉠 수 있는데 사설시조에서 특별히 부각되기 시작하는 유형은 '남성 상사형' 즉 남성화자가 여성 님에 대한 그리움을 노래하는 유형이다. 남성 상사형 사설시조는, 이전의 한국 시가의 전형적 패턴이 되어 온 '여성상사형' 즉 여성화자가 남성님을 향한 그리움과 연모의 정을 표현하는 유형과는 달리 ‘여성'이 발화와 가치의 중심에 놓인다는 특징을 지닌다. '상사형' 텍스트에서 '님'은 시적 화자에게 삶의 의미를 부여하는 가치의 총체이자 발화의 중심이 되는데 '남성 상사형'은 곧, 남성만이 차지하던 '님'의 자리에 여성도 위치하게 되었음을 알려주는 징표가 된다. 본고에서는 이를 '여성의 초점화'라는 용어로 포괄하여 사설시조 및 잡가를 통해 그 구체적인 양상을 살폈으며 근대 이후의 시에서 '마돈나' '그대' '당신'으로 지칭되는 여성 님의 존재를 부각시키는 내적 토대가 된다는 것을 검토하였다.

  • This study was attempted to develope a highly reliable and valid tool which is useful to assess the Korean obese adolescents' stress and coping method. The data were collected from the total of 600 obese students from middle and high schools in Pusan. The author used a convenience sampling method. The data collection was done from March 2 to July 11, 1999. The analysis of the data was done with SPSS Win(10.0) for descriptive statistics and factor analysis. The preliminary tool was composed of 72 items(stress items: 34, coping method items: 38) with the five point Likert scale. Item analysis and inter consistency were calculated for reliability and validity through pre-test. The preliminary tool was analyzed for reliability and validity. Finally, the tool was of 65 items(stress items: 33, coping method items: 32). The results were as follows: 1. Cronbach Coefficient Alpha for the 33 items of stress was .9485 and the 32 items of coping method was .8534. 2. The factor analysis was done in order to confirm construction and the items were extracted Oblimin rotation and Maximum likelihood extraction method. 3. The factor analysis showed 6 factors in stress and 10 factors in coping method. These 6 factors of stress explained 62.4% and 10 factors of coping method explained 57.4%. 4. Six factor of stress lable were 〈outward appearance〉, 〈boyfriend/ girlfriend〉, 〈occur an outbreak of disease〉, 〈mutual relation of family〉, 〈an obese figure〉, 〈be a burden on exercise〉. 5. Ten factor of coping method lable were 〈be concerned about another affairs〉, 〈recreation activities〉, 〈self-violence〉, 〈relaxation〉, 〈hobby activities〉, 〈avoid a situation〉, 〈communication〉, 〈music〉, 〈negative behavior〉, 〈positive thinking〉. The results of using this scale in a study will contribute to design an appropriate school health management of obese students, and also it will contribute to the development of nursing research.

  • 교육훈련의 경제적 효과에 대해서 한국노동패널을 자료를 이용하여 개인별로 살펴본 결과 본고에서는 다음과 같은 결과를 얻을 수 있었다. 교육훈련의 임금효과는 근속의 두 배에 조금 미칠 정도로 크고 유의하게 나타난다. 교육훈련은 직무내용과 고용안정, 성장 가능성의 만족에 크고 유의한 양의 효과를 갖는 것으로 나타난다. 선택편의를 통제하기 위해 임금함수의 1계차분으로 추정한 교육훈련의 임금효과는 유의하지 않다. 그러나 계속근속자와 이직경험자의 샘플로 나누어 추정하면 계속근속자의 교육훈련의 임금효과는 유의하지 않으나, 이직 경험자의 교육훈련 임금효과는 크고 유의하게 나타난다. 보다 구체적으로 기업의 비용을 부담한 교육훈련의 효과를 보면 이직 경험자의 교육훈련 임금효과는 그고 유의하게 나타나나, 계속근속자의 교육훈련 임금효과는 작고 유의하지 않게 나타난다. 이는 사용자들이 재직근로자가 교육훈련을 이수한 경우 그에 따라 임금을 올려 주지 않은 결과이다. 기업이 비용부담을 하는 경우에 교육훈련으로 인한 생산성 증가만큼 임금 증가가 이루어지지 않는 것은, 결국 기업이 교육훈련 비용부담을 개별 근로자들에게 전가하고 있음을 나타낸다고 할 수 있다.

  • A 12 week growth study was carried out to investigate the supplemental effects of dietary garlic powder (GP) on growth, feed utilization and whole body composition changes of fingerling sterlet sturgeon Acipenser ruthenus (averaging weight, 5.5 g). Following a 24-h fasting, 540 fish were randomly distributed to each of 18 tanks (30 fish/tank) under a semi-recirculation freshwater system. The GP of 0.5% (GP0.5), 1% (GP1), 1.5% (GP1.5), 2% (GP2) and 3% (GP3) was added to the control diet (GP0) containing 43% protein and 16% lipid. After the feeding trial, weight gain (WG) of fish fed GP1.5, GP2 and GP3 were significantly higher (p<0.05) than those of fish fed GP0, GP0.5 and GP1. Feed efficiency and specific growth rate (SGR) showed a similar trend to WG. Protein efficiency ratio of fish fed GP1.5, GP2, and GP3 were significantly higher (p<0.05) than those of fish groups fed the other diets. A significant difference (p<0.05) was found in whole body composition (moisture, crude protein, crude lipid, ash, and fiber) of fish at the end of the experiment. Significantly higher (p<0.05) protein and lipid retention efficiencies (PRE and LRE) were also found in GP1.5, GP2, and GP3 groups. Broken-line regression model analysis and second order polynomial regression model analysis relation on the basis of SGR and WG indicated that the dietary optimal GP level could be greater than 1.77% and 1.79%, but less than 2.95% and 3.18% in fingerling sterlet sturgeon. The present study suggested that dietary GP for fingerling sterlet sturgeon could positively affect growth performance and protein retention.
