A case of an enormous frontal sinus pyocele (accompanied with septum defect and fistula formation) with right chronic maxillary sinusitis and ethmoiditis is reported with a review of literatures. The patient was a farmer, aged 53, who complained of right exophthalmus, a swelling that occured on the superior portion of right inner canthus, rhinorrhoea and anosmia. After the Killian' s operation. procedure, the patient made an uneventful recovery. Macro, and Microscopic findings of this pyocele were as follows : 1. The pyocele was filled with a large cyst containing 50cc of thick muco-purulent secretion showed weak acid reaction. 2. It was confirmed that the septum was almost defected. 3. The microscopic examination of the purulent secretion revealed; cholesterin crystal, destroyed leucocytes, staphylococci aureus, and pneumococci. 4. Histologic examination of the wall of this pyocele revealed; the distended, catarrhal, and mu.co-periosteal lining of the sinus throughout.

In an attempt to further clarify the effect of X·irradiation on the activity of surfactant in rabbits, X-ray in dose of 900r was irradiated to the lung tissues of rabbits in vitro. Tension-area diagram of the lung extract was recorded automatically by a modified Langmuir-Wilhelmy balance with a synchronized recording system designed in this department. The surface tension of the lung extract was measured at 1,3,5,24 and 48 hours post-irradiation, and the results were compared with the non·irradiated normal group. The result$ thus obtained are summarized as follows: I The maximal surface tension, minimal surface tension, width of the tension·area diagram at the surface area of 40% in the lung extract and stability index of the normal rabbit long extract were 40.73 dynes/cm, 8.96 dynes/cm, 20.71 dynes/cm and 1.28, respectively. II. When 900r of X-ray was irradiated to the lung in vitro, 1) The maximal and minimal surface tensions did not differ noticeably from the normal at 1,3, and 5 post-irradiation hours, but the minimal surface tension increased significantly at 24 and 48 hours Post-irradiation. 2) The width of the tension area at the surface area of 40% showed a tendency of decrease throughout the experiment. 3) The stability index showed no significant change at 1,3 and 5 post-irradiation hours,but at 24 and 48 hours post-irradiation a significant decrease was observed comparing with the control. III. Activity of surfactant was significantly depressed by X·irradiation in vitro especially at 24 and 48 hours post-irradiation.

TV홈쇼핑 시장의 경쟁요인

이영철,조중환 한국유통학회 2003 유통비즈니스리뷰 Vol.3 No.-

최근 내수경기의 불황에도 불구하고 지속적인 고성장세를 보이고 있는 TV홈쇼핑 시장에 대한 산업 전체적인 측면에서 경쟁요인을 분석하였다. 그 결과로써 정부와 업계에 향후 TV 홈쇼핑 시장의 발전 방향을 제시하고 국내 유통시장의 발전추세와 구조적 특성을 파악함으로써 정책적인 제언을 하고자 한다. 이를 위해 TV홈쇼핑 시장의 경쟁요인을 외부경쟁요인과 내부경쟁요인으로 분류하였다. 구체적으로 외부경쟁요인은 업태 특징에 의한 경쟁요인과 국내ㆍ외적 유통산업 변화추세에 따른 경쟁요인으로, 내부경쟁요인은 CATV 시청자구수의 변화, 신규사업자 진출, 시장집중도, 수익률 향상 전략, SO채널확보 및 투자 인터넷쇼핑몰 운영 등으로 분류하여 분석하였다. 이러한 TV 홈쇼핑 시장의 내부ㆍ외부경쟁요인의 도출을 통해 업계에는 효율적인 전략의 일환으로 인터넷쇼핑몰의 매출비중확대, M-Commerce와 B2B 전자상거래 부분으로의 사업확대, 온라인과 오프라인의 연계방안 강구를 통한 틈새시장개발, 고객정보 확보를 통한 CRM, SCM 활용 및 개발 등을 제시하고, 정부에는 업체간 경쟁유발을 통한 소비자의 편익증대, 경쟁확대로 인한 소비자 피해최소화, 유통 인프라에 대한 투자확대 및 제도 보완 등을 정책방향으로 제시하고자 한다.

IPTV를 통한 상품 판매형 T-Commerce의 발전 모델에 관한 연구 - 정보제공 유형에 따른 성공요인을 중심으로 -

In light of the fact that the fusion concept of broadcasting and communication has been generalized and potential growth of IPTV leading such trend has been highly evaluated, the present study was intended to evaluate the measures that will boost the new retail pattern emerging in line with activated IPTV-based T-Commerce, facing up to reality that it has yet to move away from the traditional TV home shopping or Internet shopping mall pattern, and to that end, document study and survey were conducted in this study in an attempt to identify the factors for users’ preference between the independent service and interlinking service, which are sort of T-Commerce services provided depending on type of information. There are only three years to the obligation of digital broadcasting now. DCATV was expected to be activated as media which could replace the existing one-way CATV. However, as IPTV, digital TV media of new concept which adopts the concept of communication to broadcasting, is acknowledged as broadcasting and is vigorously competing with DCATV, it is rapidly growing based on the existing strong internet infra and the numbers of users. In addition, T-Commerce industry, which planned to utilize DCATV media, is expanding its investment to IPTV and tries to prepare for proper contents and broadcasting platform. It is because the conceptual basis of DCATV is not comprehensive and has its limits to adopt and realize various functions by introducing digital broadcasting in the user environment of CATV in providing a lot of channels and contents for viewers. However, in the current situation that the T-commerce is developing to the synchronized way rather than the existing independent way and the development and distribution of digital contents are needed accordingly, it can be said that both DCATV and IPTV have no problem to accept synchronized broadcasting contents and use them. However, DCATV companies are making every possible efforts to develop competitive factors to compete with the compatibility and expandability of IPTV and to build up user environment which can accept interactive broadcasting contents and provide the ease of use for views. However, the capability of IPTV to secure potential customers and viewers through the active use of internet infra can be said to be powerful. A 2-month survey of 150 respondents for positive analysis was conducted, beginning in June through August 2009 and consequently, 120 effective samples were taken which were categorized by convenience, usefulness ad accessibility based on service selected to develop the inquiries. And after defining each factor as independent variable, while the selection level between independent service and interlinking service was defined as dependent variable, the survey was conducted to identify whether and what independent variable has effect on dependent variables, making use of multiple regression analysis . As a result, the factors of interlinking service appeared to be greater than those of independent service, indicating more interest of users, and the selection was made considering more various factors. That is, the users appeared to be more interested in sense of perception, in other word, whether the useful information on products is offered, security of payment system is granted and the convenience in using remote is secured, whereas the users were less interested in independent service because of its simple service and low accessibility. So far, the level of customers’ understanding about T-Commerce is very low in Korea. The biggest difficulty in the survey for the empirical analysis was to get people understand about T-commerce. However, our customers’ receptivity and understanding about digital culture are great and rapidly grow. Therefore, for the three years left before the obligation of digital broadcasting, social understanding about the convergence of broadcasting and telecommunication should be improved, and our own broadcasti... 방송과 통신의 융합 개념이 일반화되고 그 선두주자로 IPTV의 성장 잠재력이 높이 평가되고 있는 현 시점에서 2005년 상품 판매형 T-Commerce 사업자 10개 업체를 선정한 이 후 별다른 발전 양상을 보이지 못하고 기존의 TV홈쇼핑의 형태와 인터넷 쇼핑몰 형태를 크게 벗어나지 못하고 있는 실정이다. 이에 본 연구는 신규 매체인 IPTV를 기반으로 T-Commerce 활성화를 통한 새로운 소매업태의 출현과 성장을 위한 방안을 살펴보고자 하는 측면에서 정보 제공 유형에 따른 T-Commerce의 서비스 형태인 독립형과 연동형 서비스의 시행에 대한 소비자들의 선택 요인을 알아보기 위해 문헌조사와 설문조사를 통해 연구를 수행하였다. 연구 결과 독립형 서비스 선택 영향 요인보다 연동형 서비스 선택 영향 요인이 더 많은 것으로 나타나 소비자들이 많은 관심을 가지고 있으며 보다 다양한 요인들을 고려하여 선택하는 것으로 나타났다.
