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.

'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.

향나무와 그 變種들의 類綠關係에 關한 核學的 硏究

鄭宇珪,孫玲杰,成敏雄,金鼎錫 慶尙大學校 기초과학연구소 1992 基礎科學硏究所報 Vol.8 No.-

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.

Bryophyllum 3種의 氣孔發生에 關한 硏究

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.

방대석,정우형 금오공과대학교 2006 論文集 Vol.27 No.-

The physical properties and melt behavior of PC/ABS blends may be significantly affected by mixing equipments and processing conditions. In this study, the physical and rheological properties of PC/ABS blends in a modular interrneshing co-rotating twin screw extruder were investigated. PC and ABS were blended by different conditions such as different compositions of PC and ABS, and the several types of screw configurations in a modular interrneshing co-rotating twin screw extruder. After extrusion, the specimens were fabricated by injection molding. Then the physical properties were measured by tensile and Izod-irrpact tests. The melt behavior was observed with the capillary rheometer. Mixing and melting behaviors in the extruder were investigated by the cooling experiment for the different screw configurations.

낭종성 부갑상선 선종과 심한 골병변을 동반한 부갑상선 기능항진증은 매우 드문 질환으로서, 저자들은 양측 고관절의 통증을 초기 주소로 내원한 환자에서 고칼슘혈증과 부갑상선 호르몬 증가, 골병변의 방사선적 소견을 통해 부갑상선 기능항진증을 진단하고, 경부 초음파와 컴퓨터 단층 촬영, 부갑상선 스캔검사 및 수술중 부갑상선 낭종액 검사 등을 통해 기능성 부갑상선 낭종의 한 종류인 낭종성 부갑상선 선종을 진단하고 수술적 제거를 통하여 정상화된 1예를 경험하였다. A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

Background: To examine the influencing factors on patients' satisfaction in the emergency department(ED) for quality assurance. Methods: Patients who visited to the ED were prospectively investigated from November 1 to December 31, 1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction. A Chi-square test and LISREL 7.0 were applied for statistical analysis. Results: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfation, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. Conclusions: The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust for doctors. Willingness for revisit and willingness for recommendation are influenced by patients' satisfation. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfactoin in the ED.
