The modes of narratives and communication have expanded due to social and cultural changes and technological development. Thus texts have become multimodal and media hybridities and media crossover have been increasing as well. Multimodality requires new literacy to understand and interpret those multimodal texts other than existing traditional literacy approaches. The New London Group (2000) argues that multiliteracies are needed to serve today's changing multimodal texts. Kress (2003) also argues, visual texts have been prevailing, being mingled with other modes of texts such as linguistic, audio, gestural, and spatial modes. Literary texts are not exception in this trend of multimodality. The recent renaissance of comics, in particular, the new light on graphic novels can be interpreted in this historical vein. In comparison to comics, no consensus has been made in defining graphic novels, however, many studies have been recently conducted in order to look into the potential of graphic novels in building multiliteracies. In this paper, the graphic novel as a literary genre are explored from a histocial perspective and the definition of graphic novels was attempted to be made. In the light of multiliteracies, this paper presented cases that show how graphic novels can be utilized to build multiliteracies. Lastly, the use of graphic novels for English as a foreign language was introduced as well. The author hopes that at the age of multimodality, the potential graphic novels have in language and literacy education can be taken into account by language teachers and students in expanding their territory of literacy.

Background: A number of association studies have been carried out to investigate the relationship between genetic polymorphisms in DNA repair genes and response to radiotherapy-based multimodality treatment of patients with rectal cancer. However, their conclusions were inconsistent. The objective of the present study was to assess the role of DNA repair gene genetic polymorphisms in predicting genetic biomarkers of the response in rectal cancer patients treated with neoadjuvant chemoradiation. Materials and Methods: Studies were retrieved by searching the PubMed database, Cochrane Library, Embase, and ISI Web of Knowledge. We conducted a meta-analysis to evaluate the association between genetic polymorphisms and the response in rectal cancer treated with neoadjuvant chemoradiation by checking odds ratios (ORs) and 95% confidence intervals (CIs). Results: Data were extracted from 5 clinical studies for this meta-analysis. The results showed that XRCC1 RS25487, XRCC1 RS179978, XRCC3 RS861539, ERCC1 RS11615 and ERCC2 RS13181 were not associated with the response in the radiotherapy-based multimodality treatment of patients with rectal cancer (p>0.05). Conclusions: This study shows that DNA repair gene common genetic polymorphisms are not significantly correlated with the radiotherapy-based multimodality treatment in rectal cancer patients.

Prostate cancer is the secondary most frequently diagnosed cancer in the world. Although numerous prospective randomized trial have been conducted to guide the management of patients with localized or locally advanced prostate cancer, few clinical trials targeting node-positive prostate cancer have been reported. Therefore, there are still controversies in the optimal management of node-positive prostate cancer. Recently, efficacy of multimodality treatment, including radiation therapy (RT), for such patients has been reported in several articles. The results indicate potential benefit of RT both in adjuvant therapy after prostatectomy and in definitive therapy for node-positive prostate cancer. The aim in this article was to summarize the current evidence for RT and evaluate the role in multimodality treatment for patients with node-positive prostate cancer.

Pulmonary hypertension (PH) is defined as resting mean pulmonary artery pressure ${\geq}25mmHg$ and is caused by multiple etiologies including heart, lung or other systemic diseases. Evaluation of right ventricular (RV) function in PH is very important to plan treatment and determine prognosis. However, quantification of volume and function of the RV remains difficult due to complicated RV geometry. A number of imaging tools has been utilized to diagnose PH and assess RV function. Each imaging technique including conventional echocardiography, three-dimensional echocardiography, strain echocardiography, computed tomography and cardiac magnetic resonance imaging has-advantages and limitations and can provide unique information. In this article, we provide a comprehensive review of the utility, advantages and shortcomings of the multimodality imaging used to evaluate patients with PH.

The survival rate for rhabdomyosarcoma (RMS) has significantly improved after the introduction of combined multimodality treatment. We report the 20-year treatment outcome of pediatric rhabdomyosarcoma in a single institution. The medical records of 16 patients treated for rhabdomyosarcoma between December 1986 and August 2007 at the Department of Pediatric Surgery, Seoul National University Children's Hospital, were retrospectively reviewed. Mean age at diagnosis was 7.1 years (range: 1.3 -14.2 years). Retroperitoneum was the most common primary site (n=7, 43.8 %), and embryonal type was predominant (n=11, 6 %). Before the treatment, most patients were in advanced TNM stage (stage III 50 %, IV; 25 %). The patient distribution according to the Intergroup Rhabdomyosarcoma Study Clinical Grouping System (IRS-CGS) was as follows; Group I 31.3 %, Group II 12.5 %, Group III 31.3 % and Group IV 25 %. Patients were classified into three groups according to the extent of resection of the primary tumor; complete resection (CR, n=5; 31.3 %), gross total resection (GTR, n=7; 43.8 %) and incomplete resection (IR, n=4; 25 %). Recurrence was observed in 9 patients (56.3 %) while there was no recurrence in CR patients. All patients with recurrence were identified as moderate or high-risk according to the IRS-V Risk Group. Pre-treatment TNM stage of RMS in our institution was advanced with aggressive clinical feature, however postsurgical conditions according to IRS-CGS were similar to the previous reports by IRS. This suggests that down-staging of IRS-CGS was achieved with multimodality treatment with CR or GTR. It also suggests that complete resection is the most important prognostic factor in the treatment of RMS in children. Patients classified as moderate or high-risk need close follow-up due to high recurrence rate. In case of localized recurrence, better outcome may be achieved with multimodality treatment including limited surgery.

방사선치료 계획시 다중영상의 장점들을 활용하여 종양부위 설정의 정확도를 높일 수 있는 방법들이 연구되고 있다 본 연구에서는 다중영상의 장점들을 적절히 활용하기 위해 선행되어야 하는 영상정합과 관련하여 정확도 및 실용성 측면에서 현재 가장 많이 사용되고 있는 chamfer matching 알고리즘과 mutual information maximization 알고리즘을 분석하여 정합 대상 영상들의 특성에 따라 정확도 측면에서 더 적합한 영상정합 방법을 도출하고자 하였다. 이를 위해 다중영상 획득이 가능하게 설계, 제작한 폐 팬텀을 대상으로 CT, MRI, SPECT 영상을 획득하였고, 분석대상으로 선정된 두 정합 알고리즘을 효과적으로 구현할 수 있는 프로그램을 개발하였다. 서로 다른 발현기전의 영상간 정합을 수행하여, 정합 대상 영상의 해상도 및 영상 정보 손실에 따른 정합 결과의 정확도를 분석하였다. 다중영상간 정합 결과, 두 정합 알고리즘 모두 이동거리 평균 오차 2.3 mm, 회전각도 평균 오차 $1.5^{\circ}$ 내의 결과를 보여 다중영상 정합에 있어 모두 타당성 있는 방법임을 검증할 수 있었으나, chamfer matching 방법의 경우, 낮은 해상도의 영상과 손상된 영상에서의 정합 결과는 mutual information 방법의 경우와 비교하여 상대적으로 증가된 정합 오차를 보였다. 본 연구결과, mutual information 방법은 chamfer matching 방법에서 선행되어야 하는 contour 추출과정을 필요로 하지 않고, 영상 특성에 큰 영향 없이 정확한 정합결과를 도출하여, 다중 영상간 정합 알고리즘으로 좀 더 양호한 방법임을 확인할 수 있었다.생존율은 각장 10 cm 시험구에서 98.10% 이었으며, 다른 시험구(90.95~94.76%)보다 높게 나타났다. 한편, 자연발생적으로 서식하는 원서식지와 이식지에 있어서 키조개의 성장률은 이식지가 원서식지보다 각장, 전중량, 육중량 및 패주중량이 각각 1.3배, 2.6배, 2.7배 및 4.5배씩 더 증가하였다.졌다.부의 H pylori 균체 밀도가 유의하게 감소하였다 (p<0.05). IgY정제 투여군에서 위체부의 만성 염증 활성도가 감소하는 경항을 보였다. IgY 함유 계란 투여군에서 위전정부 및 위체부의 장상피화생과 위축도는 치료전후 변화가 없었다. IgY정제 투여군의 1예에서만 치료전 위전정부에 경도의 장상피화생이 관찰되었으며 치료후 정상으로 호전되었다. 위점막 위축은 대상환자 모두에서 치료전후 변화가 없었다. 이용 가능성이 전망된다. 다소 높은 경향이었으나 유의성이 없었고, PNMTs의 발현정도는 OVX＋Oil군과 OVX＋E$_2$군 모두에서 부신 > SNC >시상하부 순으로 나타났다. PNMTs 발현에 미치는 estradiol의 효과로 SNc에서는 유의한 감소를, 부신에서는 유의한 증가를, 그리고 시상하부에서는 통계적 유의성은 없으나 증가하는 경향을 보였다. 본 연구에서는 카테콜아민 생합성 효소들의 유전자 발현의 조절에 미치는 estrogen의 영향이 세포기원이 neural crest cell인 부신 수질은 물론 뇌의 상이한 지역간에서도 조직특이적임을 관찰하였다. 이러한 결과는 각 조직에서의 estrogen 수용체 유형의 차이, 작용 모드와 각 효소 유전자 발현 사이에 중요한 상관관계가 있음을 시사한다.아 대봉광상의 광화유체에 대한 기원과 진화과정을 두 가지로 생각할 수 있다
