브랜드 자산과 통합커뮤니케이션, 그리고 미디어 시너지 효과
심재철 ( Sim Jae Cheol ),윤태일 ( Yun Tae Il ) 한국PR학회 2003 PR연구 Vol.7 No.1
This study defines brand equity as the differential effect of brand knowledge on consumer response to the marketing of the brand. Following Keller`s conceptualization, brand equity could be considered the added value of various consumer responses to previously unknown products based upon brand knowledge obtained through marketing efforts. Using this concept, we divide braud knowledge into two dimensions : brand awareness and brand image. Keller argues that the value of brand equity is more likely to increase when consumers are accustomed with the braud and fold some favorable, strong, and unique brand associations in their memory. Following this principle, any marketing specialist can improve brand awareness through advertising and public relations. In order to maximize the marketing influence, this study examines the basic concepts, opportunities and difficulties with media synergy effects. This study also deals with the many conceptual and methodological difficulties of media synergy effects, including the combined media use of television, radio, and newspapers.

본 논문에서는 n 차원 하이퍼큐브에서 n-1 노드의 결함을 허용하는 결함 허용 라우팅 알고리즘과 이를 위한 라우터의 구조를 제시한다. 제안된 알고리즘은 Chiu가 제안한 4개의 결함 상태를 사용하며, 원시노드와 목적 노드의 거리가 p일 때 라우팅에 사용된 경로의 길이는 p+4 이하이다. 그러나 Chiu의 알고리즘이 5개의 가상 채널을 필요로 하는 반면 제안된 알고리즘은 2개의 가상 채널과 선점 기능을 사용하여 교착 상태를 회피한다. 하드웨어의 복잡도를 비교하기 위하여 Chiu의 알고리즘과 제안된 알고리즘은 VHDL을 사용하여 합성되었으며 성능 평가를 위한 모의 실험이 수행되었다. 모의 실험 결과는 제안된 알고리즘이 2개의 가상 채널의 적은 면적으로도 처리량과 통신 지연의 면에서 대등한 성능을 갖고, 특히 결함 상태가 심한 상황에서는 보다 우월한 성능을 발휘함을 확인하였다. In this paper, we propose a fault-tolerant circuit-switched routing algorithm and the corresponding router architecture that tolerates up to n-l node faults in an n-dimensional hypercube. The algorithm uses Chiu's 4 fault states and can route a message whose path length is no greater than p+4, where p is the minimum distance from the source to the destination. While 5 virtual channels are needed in Chiu's algorithm, ours uses only 2 virtual channels. It allows preemption for the required channels to avoid deadlock if needed. For comparison, VHDL syntheses and simulation have been performed for Chiu's and our algorithm. The simulation results show that, although the proposed algorithm requires only two virtual channels, thus smaller area, it performs comparably and even better in worst cases, in terms of throughput and communication latency.

N/A Objective; This study was conducted to evaluate the effect of pregnancy on the activities of oxygen hee radical generating and scavenging system in the female rats. Material & Method; Rats weighing 200-220 gm were grouped to non-pregnant, 2nd trimester and 3rd trimester of pregnancy. The experiment was carried out following overnight fasting. Animals were anesthetized by administration of pentothal sodium, and blood was drawn via abdominal aorta. After exsanguination, the liver, kidney, heart, lung, with or without placenta tissues were excised immediately. The excised tissue was frozen in liquid nitrogen rapidly, and stored in liquid nitrogen for analysis. Results; The gain in body weight was higher in pregnant rats than in normal rats. Lipid peroxidation was not significantly different among all groups in the liver, kidney, heart, lung, and placenta tissue. Xanthine oxidase activity of the kidney in the 3rd trimester of pregnancy was lower than that of non-pregnant rats. Superoxide dismutase activity of the liver was significantly decreased in the 2nd and 3rd trimester of pegnancy compared with that of non-pregnant rats, and that of lung was also decreased than that of non-pregnant rats. Catalase activity of the kidney was decreased in the 2nd and 3rd trimester of pregnancy compared with that of non-pregnant rats. Glutathione content of the liver was markedly decreased in the 2nd and 3rd trimester of pregnancy compared with that of non-pregnant rats. Conclusion; In conclusion, these results suggest that oxygen free radical will not increase in the liver, kidney, heart, lung, and placenta during normal pregnancy, but in the cases of overproduction of oxygen free radical, the liver, kidney, and lung will have me chance of tissue damage because of decreased activity of some anti-oxidant enzymes and/or decreased amount of anti-oxidant materials.

N/A Objective: The objective of this study was to determine the relationship between the fetal doppler flow velocimetry and birth weight in low risk pregnancy population. Methods: From December 1995 to May 1996, We prospectively performed doppler study in 254 uncomplicated, term pregnant women, who visited Pohang Hospital, Dongguk University. Using pulsed color doppler, we measured umbilical artery RI, middle cerebral artery RI and middle cerebral-umbilical artery RI ratio within one week before delivery. Results: The result was that low birth weight group (below 2500gm) had very significant lationship with umbilical artery RI(P<0.01), middle cerebral artery RI(P<0.05) and middle cerebral-umbilical artery RI ratio(P<0.05), but there was no significant relationship in these blood flow indices between normal birth weight group (2501gm- 3999gm) and macrosomia group (above 4000gm). Conclusions: We concluded that application of doppler ultrasonopaphy in the assessment of fetal weight is somewhat helpful for identification of low birth weight, not for macrosomia.

목적 : Clomiphene/hMG 병합 과배란유도후 자궁강내 인공수정술에 대한 효율성을 알아보고자 하였다. 연구방법 : 1997년 7월부터 2000년 4월까지 43명의 불임환자를 대상으로 총 81주기의 과배란유도 후 자궁강내 인공수정술을 시행하였으며, 과배란유도의 방법은 월경주기 제 3일째부터 7일째까지 클로미펜을 투여하고 hMG을 제 3일째부터 격일로 투여하여 자궁강내 인공수정을 시행했다. 결과 : 시술 환자당 임신율은 39.5%(17/43)이였으며, 시술 주기당 임신율은 20.9%(17/81)였고 불임의 원인으로는 배란장애로 인한 불임이 16명으로 총 32주기였고, 자궁내막증으로 인한 불임은 4명에서 총 8주기, 일측 난관폐쇄인 경우가 2명에서 총 3주기 그리고 자궁근종인 경우가 1명으로 1주기 시행되었다. 과배란유도 후 자궁강내 인공수정술시의 각각의 임신율은 배란장애인 경우가 43.8%, 원인불명의 경우 40.0%이였고, 자궁내막증의 경우 25.0%, 일측 난관 폐쇄의 경우 50%, 자궁근종인 경우는 0%이였으며 각 주기 당 임신율은 배란장애인 경우가 21.9%, 원인불명인 경우 21.6%, 자궁내막증의 경우 12.5%, 일측 난관 폐쇄인 경우 33.3% 그리고 자궁근종의 경우 0%이었다. hCG 투여일에 시행한 질식 초음파 검사상 16mm이상인 난포수가 1개일 때 주기당 임신율은 7.9%, 2개일 때 42.3%, 3개일 때 41.7%, 4개 이상일 때 42.6%로 난포의 수가 증가함에 따라 임신율이 증가하나 2개이상인 경우 큰 차이를 보이지 않았다. 생존표분석(life table analysis)로 얻어진 누적 임신율은 1주기 21.3%, 2주기 후 36.7 %, 3주기 후70.0 %였다. 결론 : Clomiphene/hMG병합 사용한 과배란유도후 자궁강내 인공수정술은 남성 불임인자가 아닌 최소한 일측 난관이 건재한 불임 환자에서 임상적으로 유용하게 사용할 수 있는 간편하고 경제적인 불임증 치료 방법으로서 생각된다. Objectives : To determine the effect of clomiphene/hMG combined superovulation with intrauterine insemination on pregnancy outcomes. Materials and methods : Eighty-one cycles of clomiphene/hMG combined superovulation with intrauterine insemination in forty-three infertile couples were analysed retrospectively. Results : The overall pregnancy rate was 39.5% per patient and 20.9% per cycle. Each pregnancy rate of infertility due to ovulatory dysfunction, unexplained infertility and endometriosis was 43.8%, 40.0%, and 25.0% per patient respectively. Conclusions : Clomiphene/hMG superovulation with intrauterine insemination is a simple, cost effective and safe treatment modality in the management of infertility, and may improve a pregnancy rate.

Congenital intracranial teratoma is a very rare tumor. We recently experienced a case of massive congenital intracranial teratoma that discovered in a male infant of 28 weeks of gestation. A 33-year old multigravida was observed at 28 weeks gestation for
