This study tries 'interdisciplinary research' regarding the formation process of public sphere and the modern media on the Korean society. From the process where the civil society of modern ages is formed, the public sphere was condition that pulls down the feudal system of medieval Europe and appears the civil society. The modern newspaper collected the public opinion from lower part and did play a leading role which forms public sphere in Europe. Even from Korea the literary public sphere and political public sphere were developing inside the Chosun Dynasty period from lower part since 18th century. However the opening of a port became accomplished before making the printing media which is newspaper. As a result the public sphere in Korea was accomplished a conflict-structure. This study cleared where the crisis of Korean journalism is originated by presenting a conflict-structure differently with a transplantation theory or a graft hybrid hypothesis.

Purpose: This study aimed to examine the relationships among social support(family support, medical team support), hope, anxiety, and depression in patients with hematologic cancers before they received hematopoietic stem cell transplantation (HSCT) to obtain baseline data for developing a nursing intervention. Methods: The participants were 70 adult patients expecting to receive HSCT from 5 university hospitals in Seoul, Gyeonggi-do, and Jeollanam-do regions. A cross-sectional survey was done using standardized instruments for social support (Tae's Family Support Scale and Professional Medical Support Scale), hope (Kim & Lee Hope Scale), anxiety and depression (Hospital Anxiety and Depression Scale). The data were analyzed by SPSS/WIN 19.0 program using frequency, percentage, item mean and standard deviation, t-test, ANOVA, and Pearson's correlation coefficient. Results: Hope was significantly correlated with social support (r=.40, p=.001), anxiety (r=-.40, p<.001) and depression (r=-.58, p<.001). Anxiety was correlated with depression (r=.54, p<.001). Conclusion: The findings of this study show greater social support for patients who expect to receive HSCT is significantly correlated to a higher level of hope, as well as low levels of anxiety and depression. In nursing practice, clinical nurses may develop a nursing intervention to reinforce social support and hope, as well as reduce anxiety and depression for patients preparing for HSCT.

The aim of this study was to investigate phoneme recognition in postlingually deafened adults with cochlear implantation. 21-cochlear implantee were participated. They was used cochlear implants more than 1 year. In order to measure consonant performance abilities, subjects were asked for 18 items of Korean consonants in a "aCa" condition with audition alone. The scores ranged from 11 to 86 ($60{\pm}17$)%. The consonant performance abilities correlated with implanted hearing threshold level, significantly (p<.046). This results suggest that consonant performance abilities of postlingual deafened adults cochlear implantee be important for implanted hearing. They had higher correct rates for fricatives and affricatives with distinctive frequency bands than for plosives, liquids & nasals with the same or adjacent frequency bands. All subjects had confusion patterns among the consonants of the same manner of articulation. The reason of consonant confusions was caused that they couldn't recognize different intensities and durations of consonants with the same or adjacent frequency bands.

The experiment was tried to identify culture media which was suitable for seed germination and seedling growth of wild orchids, Calanthe discolor and Habenaria radiata. When seeds of Calanthe discolor, which was treated with ultrasonics for 30 minutes, were sowed in Murashige and SKoog(MS) medium, germination was much more promoted than other treatments. Seedling of C. discolor grew more rapidly in 3g/L Hyponex and 2g/L tryptone(H$_3$T$_2$) medium and 3g/L Hyponex and 2g/L peptone(H$_3$P$_2$) medium, especially in H$_3$P$_4$ medium among those media, pseudobulb became more corpulent. Habenaria radiata, whose tubers were obtained from seedlings, were sprouted more vigorously in 3g/L Hyponex and 1g/L peptone(H$_3$P$_1$) medium and 1g/L Hyponex and 2g/L peptone(H$_1$P$_2$) medium; but multiplication of tubers, growth of daughter tubers and its corpulence were well established in 1g/L Hyponex and 2g/L peptone(H$_1$P$_2$) medium.

Chondrosarcoma is one of the most common types of primary bone sarcoma. With the exception of the mesenchymal subtype, chondrosarcomas are usually low-grade lesions and rarely show multicentricity or distant metastasis. Only rare cases of multicentric chondrosarcomas have been reported in association with Ollier's disease and Maffucci's syndrome. To our knowledge, no report has been issued of a synchronous multicentric chondrosarcoma occurrence across a joint. We experienced a 30-year-old man with a synchronous monomelic juxta-articular multicentric chondrosarcoma across a shoulder joint in the absence of pulmonary and visceral metastases. He was treated by curettage and cement filling with allograft in the acromion and wedge resection with cement filling in the proximal humerus. At the 18-month follow-up, there was no evidence of recurrence, and the patient had full range of motion without pain.

The neoplastic variant of calcifying odontogenic cyst has various designation, and its malignant counterpart has been reported as aggressive epithelial ghost cell tumor or odontogenic ghost cell carcinoma. Odontogenic ghost cell carcinoma(OGCC) is a rare carcinoma first documented in 1985. It is composed of varying sized islands of anucleated cells with homogenous, pale eosinophilic cytoplasm, so called ghost cells, were admixed with nucleated cells. We report a case of maxillary OGCC developed from odontogenic epithelial tumor in a 25-year-old man with literature review.

$23{\sim}40$세 (평균 연령 31.6세)의 자궁내막증 환자35명 (1기 7명, 2기 7명, 3기 14명, 4기 7명)을 대상으로 gonadotropin-releasing hormone agonist (Goserelin) 3.6 mg을 한달 간격으로 6개월 복부의 피하에 이식한 후 자궁내막증에 대한 치료 효과와 부작용을 알아보기 위하여 매달 호르몬 검사와 증상에 대한 설문조사를 시행하였다. 투여 1개월 후 혈청 estradiol농도는 30 pg/mL이었고 이후 치료중 $10{\sim}20$ pg/mL를 유지하였으며 투여를 중간한 1개월 후 50 pg/mL로 증가하였다. 혈청 LH농도는 치료 중 유의하게 감소하였으며 투여를 중단한 후 증가하였다. FSH는 투여 1개월 후 감소하였으나 2개월후부터 계속 치료전과 같은 농도를 유지하였다. 혈청 CA-125치는 19명중 10명에서 치료전에 35 mIU/mL이상으로 증가되었으며 치료 2개월 후부터 모두 정상으로 감소되었다. 월경곤란증은 치료 3개월째 완전히 소실되었고 성교통은 치료가 끝날 때까지 20%의 환자에서 지속되었다. 백혈구수, 혈색소, 전해질, 단백질, 빌리루빈 및 간효소는 치료 중 모두 정상이었다. 혈압과 체중도 치료전, 치료중에 변화가 없었다. 투여후 86%의 환자가 안면홍조를 63%에서 질건조증을 20%가 두통, 우울을 호소하였다. 이와 같은 부작용은 투여를 중단한 1개월 후 모두 소실되었으며 부작용 때문에 투여를 중단한 예는 없었다. 이상의 결과로 GnRH-a는 난소의 estradiol생산을 완벽하게 중단시키고 골반증상을 완하시켜 자궁 내막증 치료에 효과적이라고 사료되며 안면홍조와 같은 부작용의 빈도가 높기 때문에 향후 호르몬 보충요법을 병행하는 것이 바람직 하다고 사료된다.

Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.

Background: In patients with coronary artery disease, dysfunctional hypoperfused myocardium at rest may represent either nonviable or viable hibernating myocardium. Two-dimensional echocardiography can detect regional wall motion abnormalities resulting from myocardial ischemia by dobutamine infusion. The purpose of the present study was to identify the prediction of improvement of regional left ventricular(LV) function after surgical revascularization. Materials and methods: Sixteen patients with chronic regional LV dysfunction underwent dobutamine stress echocardiography(DSE) (dobutamine: baseline, 5, 10, 20$\mu$g/kg/min) before coronary artery bypass grafting(CABG) and underwent echocardiography at least 2 months after CABG. Results: All patients were male with mean age of 58 years ranging from 42 to 73 years. The mean LV ejection fraction was 41.8% with a range from 19% to 55%. During DSE, there were no complications, also, there were no operative morbidities or mortalities. Improvement of wall motion within the dysfunctional myocardium was found in 8(50%) of 16 patients in DSE. Among them, 6 patients(75%) showed functional recovery after CABG. Another 8 patients did not show improvement of wall motion in DSE. But among them, 3 patients(38%) showed functional recovery after CABG. 84 dysfunctional segments were found in 256 segments of 16 patients. Improvement of wall motion was found in 34 of 84 segments in DSE. Among them, 23 segments(74%) showed functional recovery after CABG. Another 53 segments did not show improvement of wall motion in DSE. But among them, 12 segments(23%) showed functional recovery after CABG. The sensitivity and specificity of DSE for the prediction of postoperative improvement of segmental wall motion were 66% and 84%, respectively. The positive and negative predictive value of DSE were 74% and 77%, respectively. In patients with chronic regional LV dysfunction, think that DSE is a good predictor of the improvement of dysfunctional segments after CABG.

Purpose: The purpose of this study is to report a result of the technique that reconstruct posterior cruciate ligament (PCL) and posterolateral corner (PLC) simultaneously using a fresh-frozen Achilles tendon allograft. Materials and Methods: Forty two patients (45 legs) underwent PCL and PLC reconstruction were included. There were 38 males and 4 females. Mean age was 39 years. Used graft was a fresh frozen Achilles tendon allograft, which was divided by two size, larger one (${\emptyset}$ 10 mm) for PCL reconstruction and smaller one (${\emptyset}$ 8 mm) for PLC reconstruction. Arthroscopic reconstruction of the PCL was performed using transtibial, single incision, and single bundle technique with 10mm fresh frozen Achilles allograft tendon first. After PCL reconstruction, reconstruction procedure for posterolateral instability was performed using modified figure of "8" technique using smaller gtaft. For clinical evaluation, range of motion, posterior drawer test, varus stress test, prone external rotation (dial) test, Lysholm score, Tegner activity scale and posterior stress radiograph were used. Mean follow up period was 25 months. Results: Preoperatively posterior drawer test was 5 cases in grade II and 40 cases in grade III posterior instability. At final follow-up 22 cases returned within normal condition, 18 cases grade I and 5 cases grade II posterior instability. Though all patients showed positive result over 10 degrees in dial and varus stress test preoperatively, but only 9 cases showed positive both test at final follow-up. The range of motion deficit over $10^{\circ}$ flexion was 3 cases. Lysholm score was improved from mean 50 preoperatively to mean 83(p<0.05) and Tegner activity scale improved from mean 2.1 preoperatively to mean 4.6(p<0.05). In posterior stress radiographs, posterior displacement was improve from mean 16mm preoperatively to 4.1mm after treatment(p<0.05). All patients had improved compared to their pre-operative status as measured by physical examination such as posterior drawer test, varus stress test, dial test. Conclusion: We had successful results by combined reconstruction of the PCL & PLC with a fresh frozen Achilles tendon allograft in patients with PCL and posterolateral rotatory instability at a time.
