A method of calculating the natural frequency corresponding to the first mode of vibration of beams and tower structures, with irregular cross-sections and with arbitrary boundary conditions was developed and reported by D. H. Kim in 1974. This method has been developed for two-dimensional problems including the laminated composite plates and was proved to be very effective for the plates with arbitrary boundary conditions and irregular sections. In this paper, the result of application of this method to the clamped composite plates with non-uniform cross-section and with attached point mass/masses is presented.

불소이온도입법에 의한 불소도포가 교정용 브라켓인접 치면의 재석회화에 미치는 영향

여러 가지 불소 이용법중 환자의 규칙적인 협조가 필요하지 않는 불소이온 도입법에 의한 불소도포를 시행하여 산부식처리된 교정용 브라켓 인접 치면의 재석회화를 유도, 탈회를 방지함으로써 전문가 불소도포에 의한 교정용 브라켓 인접치면의 치아우식증 예방효과를 보고자 교정치료를 위해 발치해야 할 소구치에 2.0% NaF를 이용하여 불소이온 도입법으로 불소도포를 한후 4주뒤 발치하여 법랑질시편을 만들어 법랑질 표면 미세경도를 측정하여 다음과 같은 결과를 얻었다. 불소도포를 하지않은 대조군에 비해 불소도포 1회, 2회군 모두에서 법랑질 표면 미세경도가 증가하였다. 브라켓 기저면에 가까울수록 법랑질 표면 미세경도가 더 작게 나타났다. 불소도포 1회군보다는 2회군에서 법랑질 표면 미세경도의 증가가 더 크게 나타났으나 통계적 유의성은 보이지 않았다. 이상에서 본 실험에 사용한 방법과 같은 불소이온도입법을 이용하여 주시적인 불소도포를 시행하면 교정장치 장착으로 인한 법랑질 탈회 및 치아우식증을 상당히 예방할 수 있을 것으로 기대된다.

The propose of this research consists in understanding how the effects of Teaching Method by Questions on the achievement ability of math study and learning attitude are in the aspect of teaching and learning procedure, compared with those of the traditional teaching way. To attain the propose, the research questions have been set up as follows: [Research Question 1] How to make a teaching plan of effective Learning by Questions? [Research Question 2] Can Learning by Questions bring about a meaningful difference between two groups (experimental group and comparative group) in the aspect of the achievement ability of math study? [Research Question 3] Can Learning by Questions change the Learning attitude of the students positively? The outcome is as follows: First, it shows that the experimental group with Learning by Questions have marked more significant difference than the comparative group in the aspect of the achievement ability of math study. That is, Learning by Questions has a positive effect on the achievement ability of math study. Second, the experimental group with Learning by Questions have brought about more positive learning attitude than the comparative group without Learning by Questions.

테두리방귀버섯(Geastrum fimbriatum)과 비단빛깔때기버섯 (Clitocybe candicans) 등 한국산 담자균류 10종의 임파아구생성 촉진 효과

As a preliminary step to develop noble immunomodulatory lectins from Korean basidiomycetes, 32 species of wild mushrooms were collected and their lectin activities were screened using hemagglutination assay. As a result, cold-water extract of 21 species including Thelephora terrestris showed agglutination activities From T. terrestrisa, partially purified lectin fractions, cTTL_(50) and cTTL_(100), were prepared by extraction with cold phosphate-buffered saline (pH 7.2), precipitation with ammonium sulfate and then dialysis Of these. cTTL_(100) was found to be a strong immunomodulating lectin in that it aggluinated BALB/c erythrocytes and sarcoma 180 tumor cells at the concentration of ≥1.95 ㎍/㎖ and ≥39 ㎍/㎖, respectively, and stimulated the peritoneal macrophages to spread at 200 ㎍/㎖.

During the period from Jan. 1983 to May 1986, 36 knees of 36 patients underwent clinical evaluation, arthrography and arthroscopy. We performed 2 total open meniscectomy, 4 partial open meniscetomy, 12 arthroscopic partial meniscectomy. In the studied group, there were 13 tears medial, 16 tears of lateral and 7 tears of discoid meniscus. Statistical analyses were as follows 1. Male was affected 6 times more than female. The meniscal tears occured in the age group between 10 and 20 years old (67%). 2. The lateral menisci were affected 1.8 times than the medial. 3. The general diagnosis of torn meniscus for the 36 knees was correct by clinical evaluation for 22 (61%), by arthrography for 25 (61%), by arthroscopy for 34 (94.5%). 4. The patients who had taken arthroscopic meniscectomy had shorter hospital stay, rapid convalescence and low postoperative complication or morbidity. 5. At mean follow up of 7.2 months, 72% were rated excellent or good result.

As an effort to find out potent antitumor immunomodulatory agents from Korean basidiomycetes, the protein-polysaccharide fractions were prepared from ten mushrooms - Boletus fuscopunctatus, Collybia dryophila, Coriolus unicolor, Crepidotus sp., Galerina fasciculata. Lycoperdon pyriforme, Marasmius maximus, Psathyrella candolleana, Russula albonigra and subjected to a flow cytometrical analysis for their in vitro lymphoblastogenic activity. Among them, P. candolleana showed the most potent lymphoblastogenic effect on the BALB/c mouse splenic lymphocytes. On subtype analysis, P. candolleana was found to exert its lymphoblastogenic effect mostly on non T cells.
