‘Bristol Fairy’ 유래의 결실되는 아조변이체인 ‘Gyp99’의 실생계통으로 밝은 백색 겹꽃에 소화가 큰 ‘Gyp06-11’로부터 2008년 특성이 우수한 ‘Gyp08-2’ 계통을 선발하여 2009-2010년 2년 동안 특성평가 및 특성검정을 통해 ‘Dream Song’을 육성하였다. ‘Dream Song’의 초형은 직립형이고, 잎 모양은 피침형, 소화는 꽃잎수가 많고 암술이 2개인 백색겹꽃으로 꽃잎은 도란형, 꽃잎 끝 모양은 약간 둥근형, 꽃받침 모양은 컵형인 ‘Dream Song’ 고유의 특성을 가진다. 또한 소화의 일시개화성이 우수하고 절화수명이 매우 길며, 분지각이 작고 흰가루병에 강하고 총체벌레와 잎굴파리 등 충해에도 강해 재배적 가치가 높은 특성을 가진다. 준고냉지 여름절화 작형에서 ‘Dream Song’ 개화는 ‘Bristol Fairy’보다 17일 늦고 절간장과 화경장이 길었으며, 측지 분화가 많고 줄기가 굵었다. 또한 소화가 크고 야간 기온 22℃, 7일 이상의 고온조건에서도 기형화 발생이 없었다. ‘Dream Song’ is a cultivar of Gypsophila paniculata developed by the Jeollabuk-do Agricultural Research & Extension Services in 2010 for cut-flower production. This hybrid was bred from 121 seedlings collected from an open-pollinated population of ‘Gyp06-11’. It has novel morphological characteristics of upright plant type, lanceolate leaves, double florets with a few bright white-colored petals of obovate shape, truncate petal tips, and cup-shaped calyces. Furthermore ‘Dream Song’ has desirable cultivation characteristics including narrow branching angle, and moderate resistance to powdery mildew, thrips and leaf miners. Moreover it produces more primary branches, and longer internodes and flower stalks than reference cultivar ‘Bristol Fairy’ during summer cultivation in a subalpine area (500 m over the sea level). Flowering in ‘Dream Song’ is delayed by about 17 days as compared to ‘Bristol Fairy’. ‘Dream Song’ produces normal flowers with 2 pistils and an average of 10.4 stamens, with fewer malformed flowers than ‘Bristol Fairy’.

Purpose : To compare the proliferation potential of the epithelial cells between unicystic ameloblastoma (UA), dentigerous cyst (DC), and odontogenic keratocyst (OKC) and to correlate this proliferation potential with the radiographic features of these three pathoses. Materials and Methods : Immunohistochemical expression of PCNA, Ki-67, and cytokeratin as a proliferation marker were assessed for 15 cases of UA, 15 cases of DC, and 15 cases of OKC. The degree of immunochemical expression of three proliferation markers were correlated with the radiographic features, especially cortical expansion (negative and positive) and shape of border (scalloped and round). Results : Using PCNA and Ki-67, OKC showed the highest proliferation potential and UA the lowest. Statistically significant differences were found between the OKC and the UA (p.0.05). However, no statistically significant difference was present according to the radiographic features in all pathoses. Using cytokeratin, there was no significant differences of proliferation potential among three pathoses. Conclusions : OKC epithelium has the most intense proliferation potential, followed by the dentigeous cyst and then unicystic ameloblastoma. There is no significant relation between the radiographic features and the proliferation potential of epithelium of these three pathoses.

송학진,박영호,이만웅 동의공업대학 2001 論文集 Vol.27 No.1

In this study, we establish bootstrap control limits for EWMA chart by applying the bootstrap method, called resampling, which could not demand assumptions about pre-distribution when the process is skewed and/or the normality assumption is doubt. The results obtained in this study are summarized as follows : bootstrap EWMA control chart is developed for applying bootstrap method to EWMA chart, which is more sensitive to small shifts of process. With the purpose of eliminating a skewness of the resampling distribution, the bootstrap control limits are established by using a modified residual, and its performance is analyzed by ARL. It is shown that the bootstrap EWMA control chart developed in this study includes the properties of standard EWMA control chart that is sensitive to a small shift, and detects process in out of control more quickly than standard EWMA chart.

목적 : 한강성심병원에서는 2000년 3월 반코마이신내성 장구균이 처음 분리되어, 원내전파를 막기 위한 노력을 하였으나, 분리가 지속되었다. 따라서 이에 대한 좀더 자세하고 객관적인 자료를 얻기 위해 본원에서 분리된 반코마이신내성 장구균에 대한 임상분자 역학적 연구를 시행하게 되었다. 방법 : 2000년 3월부터 2001년 2월까지 한림대학교 한강성심병원에서 분리된 장구균을 대상으로 디스크 확산법, 최소발육억제 농도등의 측정을 통해 반코마이신 내성여부를 확인하였으며, 반코마이신내성 장구균을 대상으로 PFGE를 시행하여 형별 분석을 하였다. 결과 : 분리된 균주는 총 32균주로 모두 E. faecium이었다. 항생제 내성 검사 결과 모두 Van A형이었다. PFGE 결과 1a형이 8검체, 1b형이 5검체, 2a형이 4검체, 2b형이 4검체, 3a형이 2검체, 3b형이 5검체였고, 그 외 4, 5, 6형이 각각 1검체씩이었다. 총 32균주 중 56%(18/32)의 균주가 같은 시기, 같은 병실에서 동일한 PFGE 형을 보이면서 분리되었다. 결론 : 반코마이신내성 장구균의 PFGE 분석 결과 여러 종류의 반코마이신내성 장구균이 유행하였음을 알 수 있다. 그러나 같은 기간, 같은 병실에서 분리된 균주의 PFGE 형이 같은 것이 상당수 있었다. 이는 반코마이신내성 장구균의 원내 전파가 있었음을 의미한다. 따라서 반코마이신내성 장구균의 전파의 발생 및 전파 방지를 위해서는 보다 효과적인 감염관리 활동이 필요할 것으로 생각된다. Background: Vancomycin-resistant enterococci(VRE) have been a rising problem worldwide. In March 2000, VRE was first isolated from a patient in Hangang Sacred Heart hospital. Although efforts to prevent transmission of VRE were performed, isolations continued. So molecular epidemiological study of VRE was done. Method : The minimal inhibitory concentration(MIC) to vancomycin and teicoplanin, and pulsed field gel electrophoresis(PFGE) pattern of VRE isolated from March 2000 to February 2001 were evaluated. Results : 32 VRE were isolated. All of the VRE were Enterococcus faecium and showed Van A resistance phenotype. We found out that a significant number of VRE isolated during same period and in same room, were same PFGE patterns. (18 cases/ 32 isolates= 56%) Conclusion: This study demonstrated the spread of VRE of same PFGE patterns. It suggests the nosocomial spreads of VRE.

When Umbrella Arch Method is applied in construction of the first Ok-chon tunnel which have soft ground zone or fractured zone, the result as finite element analysis method, the PENTAGON-2D, is following. 1)There is little effect in bottom displacement due to side wall reinforcement, but side wall displacement decrease 50%. 2)Before reinforced by Umbrella Arch Method, rockbolt axial stress is 16 ton which exceed allowed axial stress, however after reinforced, that is about 5.5ton in up and down path, therefore rockbolt axial stress after reinforced is safe. 3)In shotcrete, compression stress decrease average 65% and shearing force and bending moment is decrease more than average 65%. hence shotcrete has great effect on ground reinforcement in side wall. 4)Umbrella Arch Method was proven as assistant method in fractured zone, but in long term stability, judging the fact that bottom displacement is slightly great, the tunnel invert is continued. Or bottom must be reinforced with reinforced with reference to field measurement data in excavation.

Purpose: An unexpected inflammatory cecal mass of uncertain etiology was encountered during surgery for presumed appendicitis. In this case, the surgeon couldn't exclude differential diagnosis which were severe appendicitis involving the cecal region, diverticular disease, other inflammatory bowel diseases, and neoplasm. Therefore, this finding leads to a therapeutic dilemma for the surgeon, when making surgical decisions during the operation. The aim of this study was to resolve this dilemma, a retrospective review was undertaken in this study. Methods: A retrospective study was performed to review the management of this problem at Soonchunhyang University Chunan Hospital for eight and half years from July 1991 to December 1999. A review of the emergency operation records identified 50 patients who had undergone ileocecal resection or right hemicolectomy for an inflammatory ileocecal mass of uncertain etiology when operated on for probable appendicitis. Results: Altogether, 39 patients underwent ileocecal resection, and 11 patients underwent right hemicolectomy. The final pathologic diagnosis was appendiceal abscess in 32 patients (63%), cecal diverticulitis in 7 patients (14%), neoplasm in 6 patients (12%), appendiceal phlegmon in 3 patients (6%), ileal tuberculosis in 1 patient (2%) and Anisakiasis in another patient (2%). The neoplasm of the 6 neoplasm patients was ascending colon cancer for 4 patients and cecal cancer for 2 patients. There was no mortality in this group. Conclusion: Although most inflammatory cecal masses are caused by benign disease, all cases in which the intraoperative diagnosis is unclear, any pathologic diagnosis including neoplasm cannot be ruled out. So this suggest ileocecal resection or right hemicolectomy to remove a possible underlying malignancy, and to decrease morbidity and mortality.

Greeting the local self-government age, local finance independece rate of local autonomy is on very poor state. So, the method of discharge a cleanest water with the least expense in sewage treatment is an important factor to supply clean water to Chung-Nam, Chung-Buk and Daejoen and to preserve a water quality of Daechong Lake. Therefore, in this study, we analysed not only a facilities outline of environment office and operating state for improvement of a water quality but also investment cost, maintenance cost, reduction method of working expenses for reduction of a budget. As a result of study, it is concluded to improve sewage pipe line of separate type and to install a flow control tank and to introduce a remove technique of T-N for the purpose of water quality improvement. Also, the relation of F/M ratio and outflow quality does not exist a regular proportional expression. But, water is the cleanest condition when the F/M ratio is 0.04. And, the most suitable injection rate of chemical material was 20㎎/ℓ for Al₂(SO₄)₃(8%) and 50㎎/ℓ(0.1%) for Polymer(0.1%). As a reduction method of operation cost, it is necessary to manage a technique support team and manage a foul water plant under township by environment office. As a result of comparison of an electric fee, a chemical cost, a by-produce recycle, and a facilities improvement, total expenses was reduced about 9% in 1996.

Plastic surgeons who frequently deal with trauma and deformity of the eyelids and orbits, need have an abundant knowledge of the accurate anatomical morphology and acceptable proportion of them. The normal value of the anatomical morphology and function of the eyelid has not yet been standardized in Korea. The authors measured anthropometry of normal Korean eyelids and statistically analysed in 2,151 individuals including 1,078 male and 1,073 female. Statistical analysis of these measurements offers valuable information about the chronological growth, size, and shape of healthy Korean eyelids. The results are as follows : 1. There was no significant statistical difference between the right and left sides in all measurements. 2. The growth of the eyelid reached the adult level at about 20 years of age and then the growth can be divided into 3 patterns, the first one slowly increased, the seconded one was a stationary, and the last one slowly decreased. 3. The following statistics were recorded for males and females. The cornea-lateral canthal distance was 7.9mm and 7.3mm, the diameter of the cornea was 13.8mm and 13.6mm cornea-medial canthal distance was 7.8mm and 7.5mm the horizontal dimension of the palpebral fissure was 29.7mm and 28.4mm, the vertical dimension of the palperbral fissure was 7.9mm and 8.0mm, the slant of the palperbral fissure was 9.5 degrees an 10.6 degrees, the intercanthal distance was 36.5mm and 37.2mm, the width of the glabella was 24.4mm,. and 24.1mm, the interpupillary distance was 66.1mm and 63.9mm, the ectocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the endocanthion-superior margin of the palpebral fissure distance was 14.9mm and 14.2mm, the height of the opened upper eyelid was 10.3mm and 10.0mm, the height of the closed upper eyelid was 18.2mm and 18.1mm, levator function by the Berke's method was 16.2mm and 15.6mm, MLD was 7.2mm and 7.1mm, and MRD1, was 2.7mm and 2.6mm respectively. 4. The vertical dimension of the palpebral fissure, slant of the palpebral fissure, and height of the double eyelid fold were greater in females than males. The intercanthal distance and width of the glabella was nearly the same in males and females and other measurements were greater in males than females. 5. A double eyelid fold was seen in about 36% of males and 50% of females. The average height of the double eyelid fold with the eye closed in 20 year old females was 5.2mm and 30 to 50 year old females was 5.5mm. The most frequent shape of the double eyelid fold was type 5. 6. The epicanthus was present in 58.1% in this series and existed in over 90% under age 10, but disappeared in about 90% of the people over 50. The most frequent shape of the epicanthus was tarsalis type.
