Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

한국 언론학에서의 문화연구에 대한 메타분석과 일비판

이영주,조세훈 한국여성커뮤니케이션학회 2004 미디어, 젠더 & 문화 Vol.2 No.-

문화연구에 대한 메타분석적 연구들은 연구대상의 규정에 않은 한계를 가지고 있다.분석의 구체적인 기준과 틀이 없이 수행된 인상주의적 비평이나 '암묵적 동의' 형태의 분석의 한계는 자명하다. 메타분석과 비판을 위해서는 분석과 비판의 대상으로 삼아야 할 문화연구논문들에 대한 명확한 설정이 필요하다. 우선 이 연구는 문화연구논문들의 경계 설정의 필요성에 기초해 분석의 기준과 틀을 마련하고자 한다. 또 문화연구의 대상, 이론, 방법론, 연구구조의 지형을 정토하고, 이들이 노출하고 있는 핵심적인 문제들에 대한 발견과 비판을 수행하고자 한다. 메타분석을 위해 우선 문화연구의 전통과 경계를 설정하려는 이론적 논의들을 정토하고 정리했으며, 이를 기초로 분석대상 논문들을 선택, 분류, 평가할 수 있는 기준과 모델을 구성했다. 분석대상 논문 중 이론적 논문의 경우, 다루고 있는 이론적 주제와 기술(description)의 심층성 정도를 분석했다. 분석적 논문의 경우, 연구대상, 이론적 배경, 방법론, 연구목적, 연구의 구조 항으로 나누어 분석했다. 이 연구는 분석결과들을 토대로 문화연구에서 나타나는 '전도'의 문제를 비판하고 있다. 또 전도적 연구과정의 결과로서 발생하는 연구의 탈맥락화, '두껍게 기술하기'의 실패, 이론의 사물화와 물신화를 과거의 다른 메타분석과 비평과는 다른 관점 속에서 비판하고 있다. Most of meta analytical criticism on Cultural Studies in mass communication study field have overlooked to define what is the Cultural Studies and what makes difference between Cultural Studies and studies on cultures. As a result, they analyze and criticize cultural studies' papers in the mode of `tolerated agreement' with the lack of certain criteria and analytical frame. This paper suggests, first of all, that there needs to make clear why we should call those papers Cultural Studies. this also tries to analyze researches' subjects or themes, theoretical background, methods, research structure or process and criticize limitations found in these papers. Especially, this paper criticizes `the inversion' dominating researchers and research process. they are criticized not only due to its negative effects but due to their attributes related with the vicious circle in researches. it leads to a decontextualized study, a failure in describing thick on subjects. in addition, a mode of the inversion is based on the reification of theories and the death of rethinking or rewriting given theories.

이기창,황성규,윤철훈,오세영 명지대학교 자연과학연구소 1995 자연과학논문집 Vol.12 No.-

Fluorenyl chalcone 유도체를 합성하였고 25 ±1℃의 20% dioxane-H?O 혼합용매 중에서 자외선 분광광도법을 이용하여 pH 1.0~13.0까지의 넓은 pH범위에서 가수분해 반응속도를 측정하였다. 또한 Fluoreny chalcone 유도체의 pH변화에 따른 반응속도로 측정하고, 일반염기효과, 치환기효과 및 가수 분해 생성물 확인 등으로부터 Fluorenyl chalcone 유도체에 대한 가수분해 반응속도상수를 구하였다. 이들 유도체들은 pH와 무관한 부분과 수산화 이온농도에 비례하며, pH와 무관한 부분에서는 중성의 물분자가 첨가된다. 반응속도 상수 측정으로부터 Fluorency chalcon 유도체의 가수분해 반응은 비가역 1차 반응임을 확인하였고, 치환기효과로부터 전자유인성기에 의해 반응이 촉진되는 것을 알 수 있었다. 또한, 가수분해 최종 생성물은 확인 결과 2 ~acetyl fluorene과 벤즈알데히드였다. 이러한 실험결과를 토대로 하여 Fluorenyl chalcone 유도체에 대한 가수분해 반응 메카니즘을 제안하였다. Fluorenyl chalcone derivatives were synthesis, it was measured that hydrolysis made use of ultraviolet spectrophotometry at a wide pH 1.0 ~ 13.0 range in 20% dioxane-H?O solution, 25±1℃. On the basis of general base catalysis, substitutent effect and confirmation of hydrolysis product, it was measured the reaction rate of fluorenyl chalcone derivatives for the pH change. It maybe concluded that a part was unrelated to pH and another part was in proportion to concentration of hydroxide ion: Above pH 10.0, It was in propotion to concentration of hydroxide ion, a part having no concern with pH was added to the neutral H?O molecule. From the result of measurement the reaction rate, hydrolysis of fluorenyl chalcone derivatives confirmed to the irreversible first order through measurement the substituent effect, It was found that reaction rate was accelerated first order through measurement the substituent effect, It was found that reaction rate was accelerated by electron attracting group. Also, from the result of final product, there were 2-acetyl fluorene benzaldehyde.On the basis of these findings, Hydrolysis for the fluorenyl chalcone derivative was proposed a fitting mechanism.

Torsades de pointes is a form of polymorphic ventricular tachycardia that is associated with prolongation of the QT interval, characterized by QRS complexes of progressively changing amplitude and contour that seem to revolve around the isoelectric line. The most common cause of Torsades de pointes induced by antiarrhythmic agents, occupying in certain drugs or toxin, electrolyte disturbance, congenital QT prolongation syndrome. Cardiotoxicity terfenadine, in overdose a widely used, nonsedating antihistamine, has been reported. Case after administration of terfenadine and ketoconazole causing syncope and torsades de pointes have been reported in recommended dose. We report a case of QT prolongation with torsades de pointes after therapeutic administration of terfenadine, a long acting histamine H1 receptor antagonist, together with ketoconazole, an antifungal preparation. The patient is a 43-year-old female, who experienced palpitation, dizziness and syncopal episoders after coadministration of terfenadine and ketoconazole, for a fungal infection of the skin. The ECG showing typical episodes of torsades de pointes with QT prolongation. Magnesium sulfate was given, torsades de pointes did not recur. The patient was discharged with improved condition.

Na^(+)-MMT로부터 제조한 생분해성 전분/펙틴/몬모릴로나이트 나노복합재료의 기계적 특성, 열적 특성, 그리고 산소 투과성을 연구하였다. XRD와 TEM의 결과로부터 고분자의 삽입으로 인하여 실리케이트 층간 간격이 증가하였으며, 또한 삽입형 전분/펙틴/몬모릴로나이트 나노복합재료임을 확인하였다. 합성된 전분/펙틴/몬모릴로나이트 나노복합재료의 경우 적은 양의 MMT로부터 기계적 특성과 열적 안정성이 우수함을 보였다. 그리고 전분/펙틴/몬모릴로나이트 나노복합재료의 산소 투과성은 고분자 매트릭스에 분산되어 있는 몬모릴로나이트에 의하여 현저히 저하됨을 보여주었다. Mechanical property. thermal property. and oxygen permeability of biodegradable Pectin/Starch-montmorillonite nanocomposite, prepared with Na-MMT, have been studied X-ray diffraction and TEM experiments on polymer/silicate composite samples demonstrated that the intercalation of polymer chains leads to increase in the spacing between silicate layers. In addition, it were found that the intercalated Starch/Pectin/monotmorillonite nanocomposite were prepared. It was found that the addition of only a small amount of clay was enough to improve the thermal stability- and mechanical property of Starch/Pectin/montmorillonite nanocomposite. Oxygen permeability of Starch/Pectin/montmorillonite composite was generally lower than that of pectin/starch.

Lymphangioma는 림프관에 나타나는 양성종양으로 림프관의 증식을 특징으로 한다. 이 종양의 대부분은 출생 시에 나타나며 종양의 95%정도가 10세 이전에 나타난다. 구강 내에 발생하는 경우에는 혀에서 가장 호발하며 거설증을 야기한다. 대개 양측성으로 혀의 전방 2/3부위에 나타나며 불규칙한 회색과 핑크빛을 띤 소절형태를 보인다. 본 증례 모두에서 환아들은 출생당시 혀에 lymphangioma를 지니고 태어나 거설증을 보였으며 이로 인해 개교합과 하악과성장 양상을 나타내었다. Lymphangioma에 의한 비정상적인 혀의 비대에 의해 환아의 구강과 두개안면부의 주위조직에 대한 적응 결과로 나타난 소견을 관찰하고 관련문헌을 고찰하여 다소의 지견을 얻었기에 보고하는 바이다. Lymphangioma is a benign tumor of lymphatic vessels. The majority of cases are present at birth and 95% of the tumors aroused before the age of 10 years. Oral lymphangioma may occur at various sites but are most frequent on the anterior two thirds of the tongue, where they often result in macroglossia. The lesions present nodularity with gray and pink projections. In the present cases, all the patients who had the macroglossia combined with lymphangioma showed openbite and mandibular prognathism. The purpose of this paper was to report the dental and craniofacial findings of macroglossia combined with lymphangioma and review the pertinent literature through the cases.

한국인의 공동체의식과 식문화에 대한 소고(小考)

오세영,이헌 한국식생활문화학회 2004 韓國食生活文化學會誌 Vol.19 No.5

This study examined dietary culture in Korea regarding collectivism through literature review. Based on the evidence from the origin of lineage and traditional customs, the Koreans' traditional collectivity appeared to have been grounded upon the northen nomadic culture emphasizing sentimental collectivity and harmonized with the characteristics of southern agrarian society related to mutual support and sociability. The inseparable relationship between collectivity and food was well revealed in the occasions such as rice-planting, kimchi and jang makings in which pooled labor was common as well as the gathering of mutual aid association. In these occasions, foods were offered and shared among members. Food sharing was a main activity and almost play a central role regarding the promotion of friendly relations among each other. In sacrificial memorials, food sharing was extended not only to the live persons but also to the passing spirits. Collectivity was also disclosed in the eating or table manners of Koreans. Koreans quite literally share food at every meal since the side dishes placed centrally on the table. The taste of Korean foods is completed inside the mouth by mixing foods with various combination, which let people create their own choice of taste. Therefore, the collectivity manners at the table appeared to be harmonized with individual freedom of creating his/ her own taste of foods. The collectivity is still a very important concept in modem Korean dietary culture, as reflected by an increase of restaurants served shared dishes.
