Background and Objectives 18F-fluorodeoxyglucose PET/CT scans can be a useful methodto detect recurrence. However, its role in locally advanced head and neck squamous cell carcinomas(HNSCCs) patients after definitive chemoradiotherapy (CRT) has not yet been determined. The current study was performed to identify the role of therapeutic response evaluation usingPET/CT after definitive CRT. Subjects and Method We conducted a retrospective review of patients with locally advancedHNSCCs, and who have undergone definitive CRT from 2009 to 2017 at a single institution. The patients were divided into two groups according to their responses to the treatment(metabolic complete remission [mCR] group or non-mCR group), assessed by PET/CT scansafter definitive CRT. Results Twenty-eight patients were consecutively enrolled. The most common primary siteof cancer was the oropharynx, followed by the oral cavity, hypopharynx, and nasal cavity. The therapeutic response assessed by PET/CT scans was mCR in 14 patients. The median progression-free survival (PFS) was not reached in the mCR group but was 13.3 months for thenon-mCR group (p=0.001). The median overall survival was significantly longer for the mCRgroup (52.5 months) than for the non-mCR group (15.2 months, p=0.002). A multivariate analysisshowed PET/CT response and high-sensitivity C-reactive protein (hsCRP) as independentprognostic factors for PFS (mCR: p=0.027; hsCRP: p=0.042) and for the overall survival(mCR: p=0.006; hsCRP: p=0.020). Conclusion PET/CT scans after definitive CRT predicted the prognosis in patients with locallyadvanced HNSCCs. CRP was a prognostic factor affecting the outcomes of treatments.
이 논문은 시각예술의 경제적 역할에 대한 개념적 틀을 제시하면서 시각예술 관련한 다양한통계 데이터베이스 구축을 통해 예술과 창조성의 상관관계를 분석하려는 하나의 시도이다. 문화예술 인프라가 특허출원, 브랜드 같은 경제성장에 더 직접적인 변수에 상당한 영향을 줄 수 있다는 결론이다. 특히 문화변수(cu1tural variables)를 조사하여 우리나라 문화예술의 국제적 위치에 대한 문제점을 지적하였다. 보다 엄밀한 추가연구가 중요하다. This is an preliminary attempt to collect various art related variables. Based on this international cross section data, it shows that art and cu1ture affects creativity related variables such as patents and brand in a positive way, Farther analysis is needed to verify this conclusion.
North is the fourth collection of poetry by Seamus Heaney, which was borne of his move to Southern Ireland. This collection of poems is about Northern Ireland viewed from a foreign perspective. This fact is very important in understanding the poems in this collection because it implies that many poems in this collection approach Northern political and cultural problems from an objective viewpoint. Seamus Heaney in North made an imaginative journey to the national memory bank in which Heaney believes the culture and history are preserved to seek the undiscovered consciousness of Ireland. Most of his journey is made of digging into the origins of words, speculating on the names of historical places, sympathizing with the mummies dug from the bog, or daydreaming about the archeological relics. Through this journey, Heaney makes sure of the fact that every national culture in Northern Europe had been mixed up with each other and had similar ‘growth rings’, and the vikings who had invaded Ireland had a connection with Heaney as one of his ancestors. The civilized violence in modern times has its origin in the violence of old fathers and it has the same repeated pattern from ancient times. North is most tragic among Heaney’s collections because it refuses to give any positive vision about the progress of history that could be found in Heaney’s previous collections. It merely shows a strong fear that we may not escape from the anxious fate that we might be condemned to repeat this violent tradition.
Eosinophilic gastroenteritis, a cluster of diseases of unknown etiology, is complex and confusing. Its incidence is so rare and characterized by eosinophilic infiltration of the gastrointestinal tract. In most cases the diagnosis can be made by careful evaluation with clinical findings, laboratory data, imaging studies. However, its diagnosis is not easy for us to know preoperatively. We describe herein 46-year-old man who was presented without any specific symptoms. The patient had encircling mass around secound portion of doudenum mimicking duodenal GIST. Pancreaticoduodenectomy was performed and histological study on the surgical resection specimen revealed eosinophilic duodenitis.
The issue of identity of a personal self or a cultural community has been one of the major themes throughout Western literature. This one has traditionally been an especially important concern for the writers of Ireland which had been colonized by England for a long time. Seamus Heaney often confessed that he had felt from the early time that he had constantly been threatened with the dissolution of the self. Like many postcolonial writers, many of his poems and proses express a sense of dividedness on both sides of self and culture. Heaney describes himself placed between English influence and native Irish experience. Around the time his first collection, Death of a Naturalist, was published, Heaney defined his few poems as revelation of the self to the self, as restoration of the culture to itself. But the self and the culture his poem revealed and restored do not show any continuous and unified inheritance or quality. His poems eventually imply that it is impossible that any culture continues to maintain the original quality, and that the self, even though preoccupied with the past, continually suffers from breaking off from its past and unstably stays confused among the memory of the past, and the experience of the present, and the perspective of the future. The connection between digging and writing is the most important aspect of Heaney’s poetic idea. But Heaney’s digging as writing a poem is poignantly paradoxical and contradictory because it is both an act that bonds the generations as well as an act that severs the living roots of the past. The act of setting darkness echoing, which is also another metaphor for writing, simultaneously involves a continuation of the past as well as a rupture within that continuation.
본 연구의 목적은 코스닥기업의 DEA효율성이 수익성을 결정하는 중요한 요소인지와 코스닥기업의 특성에 따라 그 영향력에 차이가 발생하는지를 보고자 한다. 본 연구에서 사용한 수익성변수는 ROE(자기자본순이익률)이며 1998년부터 2002년까지 5개년을 대상으로 1,178개의 표본을 사용하여 다중회귀분석을 실시하였으며, 분석결과는 다음과 같다. 첫째, 코스닥 일반기업의 경우 일부 산업에서 DEA효율치가 ROE에 유의한 양의 영향을 미치지 못하는 것으로 나타난 반면에, 코스닥 벤처기업외 경우에는 모든 산업에서 유의한 양의 영향을 미치는 것으로 나타났다. 둘째, 일반기업에 대한 DEA효율치의 회귀계수는 벤처기업보다 낮은 것으로 나타났으며, 상호작용항 계수도 모든 산업에서 유의한 양의 값을 보여 주었다. 본 연구는 코스닥 기업의 원가효율성 정보가 수익성에 유의한 양의 영향을 미친다는 것과 일반·벤처기업의 특성에 따라 원가효율성이 수익성에 미치는 영향력에 차이가 있음을 보여주었다는 면에서 큰 의의를 들 수 있다. We examine whether DEA(data envelopment analysis) efficiency has influence on ROE(return on equity) and study venture' firms differ from general firms in the influence of DEA efficiency on ROE. Using 1,178 samples selected for the 5-year period from 1998 to 2002, The research method is multiple regression. The empirical results are as follows. First, the coefficient on DEA efficiency of general firms is not all significantly positive, but the coefficient on DEA efficiency of venture's firms is significantly positive. Second, Because of the difference of age, the coefficient on DEA efficiency of venture's firms is the higher that on DEA efficiency of general firms. In sum, we can find that the coefficient on DEA efficiency of KOSDAQ firms is significantly positive and find a significant difference in the coefficient on DEA efficiency of venture's firms and general firms.
