우리는 『中國語文學論集』(2003, 2004, 2008a、b)에서 중국어 부사 ‘才’와 ‘의문사’의 교육문법순서배열에 대해서 토론하였다. 분석 방법으로 보면, ‘才’는 대비분석과 난이도 가설을 사용하였고, ‘의문사’분석은 대비분석과 난이도 그리고 빈도 가설을 사용하였다. 이 분석 과정 중에 우리는 몇 가지 의문점이 생겼다. 첫째, 우리가 사용하는 이론 구조는 당대 학술계에서 인정하는 연구 방법일까. 둘째, 어떻게 분석하여야 가장 완벽한 교육문법 순서배열을 설계할 수 있을까. 셋째, 분석과정은 객관적인가. 본문은 이 세 가지 의문점 중에서 두 번째와 세 번째 논점에 대하여 새로운 연구 방법과 평가 방법을 소개하고, 이를 중국어 의문사(2008a、b) 분석에 다시 적용하고자 한다. 분석 후, 우리는 박용진(2008a、b)과 본 논문의 분석에 있어 작은 차이를 보일 뿐, 상당 부분 동일하다는 것을 발견하였다. 그렇지만, 새로운 연구 방법과 평가 방법을 접목한 본 논문은 박용진(2008a、b)의 분석보다 더욱 객관적이고 과학적이며 또 설득력을 더 하였음을 인정하지 않을 수 없다.

The spheroidal graphic cast iron was made the structure of the round type by graphite grains in the cast iron, but flaky graphite cast iron was not made it. For the first time in 1948, H. Morrogh and W.J. Willians of England found out that if the cast iron of less 0.1 per cent phosphor would be contained to add more 0.02 per cent cerium in it, it could be grained the structure of spheroidal graphite on ordinary cooling condition. At the nearly same time, A.P. Gagnebin of America found out the same structure of spheroidal graphite adding more than 0.04 per cent Magnesium in grey cast iron. Since the history was not so long, but the progress of cast iron materials has developed uniquely in the invention of this nodular cast iron. The characteristics of this cast iron became the spheroidal forms as cast condition and the mechanical properties was very excellent by reason of this spheroidal forms, then tensile streirgth, elongation, abrasion resistant and corrosion resistant etc, also the put has been increasing still more. Up to the present a study on the mixed element in S.G.C.I. has been made by many research works, but it has been a fragmentary study. Because the study effects of the other composition in S.G.C.I. was very important by nature, in this study an author already has been studied on the effects of the copper in the S.G.C.I. Then this paper deals with the effect of copper in the S.G.C.I. which results from the addition of copper that has been discussed in many aspects, the results obtained are as follows: (1) With the addition of less 1 per cent copper, the shape and size of the spheroidal graphite cast iron was not changed, but the graphite grains by adding more 3.0 per cent copper proved to be perfectly flaky. (2) The effect of copper in the spherolgraphite cast iron size numbers were not conspicuous, but it was considered to a little tendency of increase. (3) The matrix structure of the spheroidal graphite cast iron became a remarkbly pearlite form by the effect of copper, but it was not so conspicuous about spheroidal graphite.

This paper examines various problems in Buddhist research by reviewing bibliographical research from Korea, China, and Japan. It suggests controversies and differences among perspectives of future directions of Buddhist research while summarizing commonalities. Titles and publishing periods were examined, which are the basis for establishing and developing the problems that arose during the research of individual bibliographies. Bibliographic items were divided into six parts: the cover, the beginning of the book, the body of the book, the plate type, the end of the book, and the publication data. This allowed for sequential research where possible from the cover to the end of each book. In addition, investigations and estimations of unknown titles and publishing periods were studied. Publication periods were estimated and suggested methodologies provided based on color and paper type, the preface and postscript, omissions, and the carvings.

1,450-1,650℃의 온도 범위의 용융규소에 10-65% CO₂의 CO·CO₂혼합가스를 1기압 정도의 가스압력으로 주입하면 일산화규소가 발생한다. 그 반응식을 다음과 같이 추정하였다. Si(ℓ)+CO₂=SiO(g)+CO ΔF_α^0=30,840-31.76T 윗 반응에 대한 실험치와 ΔH^0_(298), ΔS^0_(298) 각 성분의 열함량으로 부터 계산한 표준자유에너지 값은 잘 일치하였다. 백색, 무정형 일산화규소분말을 900-600℃에서 응축시켜 얻을 수 있었으나, 600℃ 이하에서는 2CO=CO₂+C의 보오도아 반응에 의하여 일산화규소분말위에 0.5-1.5%탄소가 석출되었다. The liquid silicon was oxidized to silicon monoxide by 10-65% CO₂ gas in CO·CO₂gas mixture under a total pressure of about 1 atmosphere at temperatures ranging from 1,450℃ to 1,650℃. The reaction equation was estimated as follows: Si(ℓ)+CO₂=SiO(g)+CO ΔF_α^0=30,840-31.67T The standard free energy change, ΔF_α^0 for the above reaction between the experimental results and calculated data from ΔH^0_(298), ΔS^0_(298) and heat capacity of each component was closely agreed with each other. White and amorphous silicon monoxide powder was obtained by condensation at 900-600℃, but 0.5-1.5% carbon was deposited on silicon monoxide powder by the Boudouard's reaction, 2CO=CO₂+C, below 600℃.

The causes of osteolytic lesions found in radiological examinations are not quite certain. Therefore, to determine the appropriate treatment method, various approaches and analyzes are required to find the real cause. Hyperparathyroidism is one of the diseases which forms osteolytic bone lesions so-called brown tumor. A 55-year-old woman who had painful osteolytic bone lesions in both hip joint areas was diagnosed as parathyroid carcinoma after serial work-up. She underwent parathyroidectomy and follow-up imaging showed a decrease in brown tumor size and bone consolidation in the subchondral bone destruction area. Proper evaluation of osteolytic bone lesions helps to avoid unnecessary operative treatments and the first choice for the treatment of osteolytic bone lesions caused by parathyroid carcinoma is parathyroidectomy.
