鄭宇珪,金鼎錫 慶尙大學校 1986 論文集 Vol.25 No.2

Bryophyllum 屬의 3種(B. crenatum, B. diagremontiana, B. tubiflorum)의 잎, 잎의 구슬눈 및 꽃잎에서 表皮構造와 氣孔의 發生을 顯微鏡으로 觀察한 結果는 다음과 같다. 表皮細胞는 各種과 各器官에서 공통적으로 多角形, 等値徑形 또는 伸張形이었다. 세포벽은 弓形 또는 波狀形이었다. 부세포벽은 얇고 대부분이 弓形이었다. 잎과 잎의 구슬눈에서 氣孔의 數는 얇은 잎을 가진 일반식물에서 보다 적었고 잎의 兩面에 分布하는 氣孔數의 차이도 일반식물의 잎의 양면에서 氣孔數보다 적었다. 성숙한 氣孔의 主類型은 螺旋型이었다. 氣孔의 發生學的 類型은 各種과 各器官에서 공통적으로 全中立形成螺旋型이었고, 이 類型은 孔邊母細胞의 分裂角에 따라 全中立形成平行螺旋型, 全中立形成不規則螺旋型 및 全中立形成直交螺旋型으로 細分되었다. 더물게 全中立形成不均等型, 全中立形成重四副細胞型 및 全中立形成四副細胞型(cotetra-ansio-eumesogenous)이 管東植物에서는 처음으로 觀察되었다. The epidermal structure and stomatal ontogeny on the epidermis of the leaves, epiphyllous buds and petals of Bryophyllum(B . diagremontiana, B. tubiflorum) were described. The epidermal cells were polygonal, isodiametric or elongated cells. The cells were arched or sinous. The subsidiary cell walls were thin and mostly arched. The number of stomata in the leaves and epiphyllous buds had relatively fewer stomata than thin-leaved common plants. The difference of stomatal number on two surfaces of the leaves was relatively fewer than that of common plants. The main type of mature stomata was helicocytic type. The ontogenetic type of stomata was mainly helico-eumesogenous type. This type was subdivided into three subtypes such as parahelico-eumesogenous, anomohelico-eumesogenous and diahelico-eumesogenous stomata on the base of the division angle of the guard mother cell. Rarely, aniso-eumesogenous, duplotetra-eumesogenous and tetra-eumesogenous types were found. The cotetra-aniso-eumesogenous type in the leaf of B. diagremontiana was firstly observed in the vascular plants.

In this study the relationship between Juniperus chinensis and its seven varieties-J. chinensis var. procumbens, J. chinensis var. horizontalis, J. chinensis var. sargentil, J. chinensis var. kaizuka, J. chinensis var. aureo-variegata, J. chinensis var. globosa, J. chinensis var. aureo-globosa and J. rigida were analyzed by electro-phoresis of two souble enzyme systems (isoperoxidase and isoesterase). The results obtained from this study were as follows : Juniperus chinensis var. sargentii and J. rigida in the study of isoenzymes, showed the variable banding patterns of isoperoxidase and they were considered to be reproduced mainly by allogamy. Other variants had similiar banding patterns among individuals and their main reproduction stratagies were asexual. The largest number of the isoperoxidase hands was observed in J. chinensis var. procumbens(12bands). Other variants had 7-11 bands. Juniperus chinensis var. procumbens and J. chinensis var. horizontalis shared the largest number of a common band which had the same molecular weight but also between the two sample trees. In each sample four to seven isoesterase bands were observed. The largest number of the isoenzyme common bands(6 bands) described above was identified between J. chinensis var. procumbens and J. chinensis var. horizontalis.

In this study the relationship among Juniperus chinensis and its seven varieties-J. chinensis var. procumbens, J. chinensis var. horizontalis, J. chinensis var sargentii, J. chinensis var, kaizuka, J. chinensis var. aureo-variegata, J. chinensis var. globosa, J. chinensis var. aureo-globosa-and J. rigida was studied by using the karyological methods. The results obtained from this study were as follows : In the karyotype analysis, J. chinensis, J. chinensis var. horizontalis, J. chinensis var. sargentii, J. chinensis var. globosa, J. chinensis var. aureo-globosa, and J. rigida were diploid with 2n=22, although J. chinensis var. procumbens, J. chinensis var. kaizuka and J. chinensis var. aureo-variegata were tetraploid with 2n=44. According to descending order of the total length of the chromosomes and the length of short and long arms, from the arrangement order of chromosomes and the position of centromeres, J. chinensis var. procumbens and J. chinensis var. horizontalis were categorized into the first group J. chinensis var. kaizuka and J. chinensis var. aureo-variegata were into the second group, and J. chinensis var, globosa and J. chinensis var. aureo-globosa were into the third group, respectively. Aneuploid(2n=26) in the C-band staining of J. chinensis var. aureo-variegata was identified, although it normally showed 2n=44 as karyotype. Because light was emitted from all chromatids of the samples by fluorescent light staining with DAPI, A-T rich regions would be located all over the chromatids.

'90년대 한국농구의 전개과정 연구

정우석,이동건 東亞大學校附設스포츠科學硏究所 2001 스포츠科學硏究論文集 Vol.19 No.-

The present study is a chronological analysis of the history of the Korean basketball, focused on a decade from 1991 through 2000. The development processes are examined in three main divisions of school basketball, adult basketball, and the Korean basketball in future. First, in school basketball, athletes' body height and skills have all but similarly developed in elementary schools' basketball throughout the nation. Middle and high school athletes have held a lot of competitions, where some promising players for adult basketball teams have been produced. In campus basketball, however, much progress was seen in the First League of Seoul and its vicinity universities, while the Second League of local colleges have merely regressed. Second, in adult basketball, considerable and visible progress was made owing to the birth of professional basketball teams and the KBL in the mid-1990s. This opened a new chapter in the Korean basketball history, resulting in an epoch-making stride of the overall Korean basketball, heightening the levels of participation and consciousness of the players and the basketball-concerned people, and triggering further development in sports marketing and sports administration. Last, in the world arena, the Korean basketball has failed to capture any championships (including the ABC) in the 1990s since it earned the silver medal in women's basketball in the 1984 LA Olympics. After the birth of the WKBL, however, the Korean women's representative team made another myth by standing the 4th in the 2000 Sydney Olympic Games. Therefore, the Korean basketball should hold even more regional contests for the purpose of achieving standardization or equalization among the various levels of school teams across the country. Adult teams also need to grow their athletic performance based on fair play and real sportsmanship, not on excessive commercialism. This also applies to the Korean basketball in the world stage, where pure and authentic sportsmanship is emphasized.

In this study, some of results from a study conducted on the preparation of niobium coated hematite particles to be used as a catalyst are presented.α-Fe_2O_3 (hematite) particles obtained by aging an acidic solution of ferric(Ⅲ) ions at high temperature were first prepared as core particles and synthesised by hydrolysis at high temperature with layers of amorphous niobium pentaoxide (Nb_2O_5) deposited by the hydrolysis of niobium pentachloride. The effects of varying molecular ratio of Nb/Fe (10/1, 5/1, 1/2, 1/5, 1/10) were studied. The synthesised particles were characterized for their physical and chemical properties using XRD, SEM, TPD, BET etc. The process of the surface coating showed heterocoagulation rather than surface nucleation and growth. A preliminary investigation of the acidic characterization and specific surface area of the synthesised particles showed that these particles can achieve an acidic characteristic changed and enhanced specific surface area of that of pure niobia and α-Fe_2O_3 prepared here.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.

Capsicum chinense, 재래종 및 저항성 고추 유전자원에서 역병 저항성 계통 선발

2000년도에 검정에서 역병에 살아남은 개체들로부터 채종하여 육성한 Capsicum chinense 31계통에 대하여 역병 저항성을 검정한 결과 고도의 저항성을 나타내는 것은 발견되지 않았다. 2001년도의 검정에서 역병에 살아남은 개체로부터 채종한 재래종 26계통에 대하여 다시 역병 저항성 검정을 실시한 결과 KC180, KC230, KC195, KC194에서 다수의 개체가 살아남아 저항성을 나타내었다. 그러나 KC180과 KC230은 각각 AC2258과 CM334와 혼종된 것으로 관찰되었다. KC195와 KC194는 재래종의 형질을 유지하고 있는 것으로 관찰되었다. CM334의 보존 증식과정에 자연교잡이 일어난 것으로 보여 이의 순도향상을 위하여 채종년도별로 시료를 꺼내어 역병저항성 검정을 실시한 결과 가장 오래된 1992년도 채종종자에서부터 약간의 이형주가 관찰도기 시작하여 1995년부터 2001년도까지 시간이 경과함에 따라 많이 변형되어 있는 것을 알 수 있었다. 1992년도 종자에서 이형주를 제거하고 원형의 개체로부터 자식종자를 대량으로 채종하였다. 함께 공시한 AC2258은 순수한 것으로 확인되었다. 1995년도 채종 CM334 종자에서는 비록 혼종은 되었으나 측지발생이 적은 개체들이 발견되어 이들을 개체 선발하여 역병에 저항성이며 측지발생이 적은 계통으로 육성하고 있다. A total of 31 c. chinense lines selected from 2000 screening were tested again for resistance to P. capsici but resistance was not found in the lines. A total of 26 selections from Korean land races tested 2001 spring were tested again for resistance to P. capsici. KC180, KC230, KC195 and KC194 showed moderate resistance to P. capsici. However, it was apparent on the basis of hortivultural characteristics that KC180 and KC230 had been naturally crossed with AC2258 and CM334, respectively. CM334 and AC2248 seed lots that were increased in different years were taken out and tested for resistance to improve their genetic purity because the resistant genetic resources have been showing some off-types in the population. Off-types began to be found in 1992 seed lots and the proportion and degree of the offs was increasing with time up to 2001. Plants true to the type in 1992 seed lots were selected and their inbred seeds were mass produced in a net cage in the greenhouse. AC2258 included in the experiment number of lateral branching at cotyledonary axil, although they were off from the original in the experiment together was uniform. In 1995 seed lost of CM334, plants with resistance to P. capsici and low or no number of lateral branching at cotyledonary axil, although they were off from the original CM334, were found and selection was applied to breed lines fixed in the characters.
