이호섭,Lee, Ho-Seoub 대한경영정보학회 2007 경영과 정보연구 Vol.23 No.-

In the highly competitive and divers world of financial market, customer is the single most important factor to company's survival. Especially, creating a relationship with valued customers is a key to success. CRM provides the mean to retain high value customers. It takes a prospect of what customers expect. Utilizing those knowledge can help the products and service meet the customers' needs, thereby maximizing customer satisfaction and company's profit. In this report, I am going to suggest a few ways to develop successful CRM in the life insurance industry. First, CRM should innovate the way of communication to keep pace with Web 2.0 era. In other words, the customer's needs should be caught by real-time communication than traditional off-line market research. Thus, the functionality and specification of products can be decided by customer's direct choice so that the customers are able to purchase the understanding and experience of the products. Second, CRM project should consider whether the initial strategy plan can promise the stable growth of customer at the first step. When planning strategy, the project needs to identify what customer wants and how to fulfill the needs with stable growth of the customer. In addition, the CRM should be developed by realizing that customer centric benefits ultimately guarantee the growth of the organization. Third, CRM systems should enhance the organization's ability to take the customer's insight in a 360 degree view and to capture the voice of the customer directly. In order to develop the best matched product package, more precise customer segmentation should be ahead of market segmentation strategy. Forth, the biggest reward from CRM will be a customer royalty program. Many successful banks are already planning and practicing customer royalty strategy. A comprehensive analysis of customers and their behavior allow organization to identify high value potential customers' needs and determine a strategy required to meet those needs. Even life insurance companies such as Prudential Korea are developing products designed for royal customers. Fifth, understanding and managing the experience of customer called Customer Experience Management also can increase customer satisfaction. Measuring only customers' experience and adapting it to marketing strategy make products position in the gap between the customers' expectation and experience not required by market. A key component of CEM is its application across all organizational functions. At last, the direction of change and development of CRM can be defined from the conceptualization of information technology represented by Ubiquitous and Web 2.0. Instead of just managing customer information, companies should take the initiative in personalized system with customer oriented strategy. Furthermore, with the regular communication between CRM stakeholders (Sales-Marketing-IT), customer's demand should be directly reflected to enterprise strategy in real time.

This study was designed to investigate the effects of Korean Lycii Fructus water extract in Pb-administered rats. The Pb exposed rats were given 100 ppm and 200 ppm in the distilled water. Sixty male Sprague-Dawley rats weighing between 90 and 110g were blocked into 6 groups according to body weight. The control group was fed a normal diet, without lead. The experimental groups, which was fed a normal diet plus 100 ppm and 200 ppm lead, and one group received a normal diet plus Lycii Fructus water extracts. The results: the Food intake, the weight gain, and the kidney weight content in the cadmium added groups were lower than those in the Lycii Fructus water extracts group. The contents of Pb in the kidneys of the rats were determined by using ICP(lnductively Coupled Plasma Spectrophotometer). The accumulation of lead in the kidney was lower in the Lycii Fructus water extracts group. The Plasma levels of renin activity was higher in the lead administration groups, as compared with the Lycii Fructus water extracts. Plasma levels of aldosterone activity was higher in the lead administration group, as compared with Lycii Fructus water extracts. These results suggest that Lycii Fructus water extracts has a lowering effects on the accumulation of pb on kidney and it is believed that the Lycii Fructus water extracts have some protective effects on lead-induced nephrotoxicity in rats, but the mechanism of these effects was obscure.

본 논문에서는 정지궤도 위성을 운용하는 위성통신환경에서 이동형 위성단말의 송신전력제어를 위한 개루프 전력제어 알고리즘을 제안한다. 제안하는 알고리즘은 위성체로부터 전송되는 비콘 신호를 기준으로 현재 위성채널 상태가 장애물에 의해 LOS가 제한되는 상황인지, 안테나의 위성추적 오차로 인해 발생되는 손실인지 판별한다. 판별된 신호감쇄 원인을 기준으로 안테나 위성추적 오차 시는 RF 출력을 멈추며, 장애물에 의한 채널 단절이 발생될 경우는 전력제어 없이 확산을 통해 데이터 수신 확률을 향상시킨다. 제안하는 알고리즘의 성능분석을 위해 인접위성 간섭 수준과 채널 아웃티지 확률을 분석하였으며, 분석결과 제안하는 알고리즘이 더 높은 성능을 보임을 확인하였다. In this paper, we propose an open loop power control algorithm to control transmission power of the On-The-Move(OTM) Satcom terminal in GEO satellite communication environment. The proposed algorithm identifies the current channel state restricted by an obstacle or an antenna depointing loss based on the received beacon signal strength. On the basis of the determined signal attenuation causes, the OTM Satcom terminal turns off the RF output when an antenna tracking is failed. If the OTM Satcom terminal experiences a channel blockage by an obstacle, the terminal spreads the transmit data to increase data reception probability. To evaluate the performance of the proposed algorithm, we compare an adjacent satellite interference level and an outage probability. The results show the performance of the proposed algorithm is better than that of the conventional algorithm.

성·복토용으로 사용된 전로제강슬래그가 주변 토양환경에 미치는 영향

The effect of blast oxygen furnace (BOF) slag used as filling materials on the soil environment was studied using column tests that simulated the flow of the BOF slag leachate through the soil layer. The Cu, Mn, Zn, Ni, and F contents of the leachate affected soil were similar to that of the controls (i.e., soils that were not affected by the leachate). The As, Cd, and Pb contents were lower in the leachate affected soils than the controls. The changes in these contaminants contents can be attributed to the interactions between anions such as alkalinity generating anions (e.g., CO₃²⁻, HCO₃⁻, OH⁻) or calcium ions with heavy metals or F, which consequently affected the fate of heavy metals and F in the leachate affected soils. The germination and growth of Spinapis alba in the soils affected by the leachate and the controls were also similar. However, the proportion of alkalophilic bacteria in the soils affected by the leachate significantly increased, and this can be explained by the increased soil pH due to the alkaline leachate. Overall, this study shows that the alkalinity of the BOF slag leachate, rather than the presence of heavy metals and F in the leachate, needs to be considered when the BOF slag is to be reused as structural filling materials.

생약 추출물에 의한 superoxide와 hydroxyl 라디칼 소거능 검색 방법의 개선

이호섭,강대길,Lee, Ho-Sub,Kang, Dae-Gill 한국생약학회 2001 생약학회지 Vol.32 No.3

The present study was designed for the improvement of routine measurement of superoxide and hydroxyl radical scavenging activities utilized by a microplate reader. Superoxide radical scavenging activity by the ascorbic acid, which is a well-known superoxide scavenger, was determined in a dose-dependent manner. Hydroxyl radical scavenging activity by the thiourea, which is a well-known hydroxyl radical scavenger, was also well detected in a dose-dependent manner. Our results suggest that the use of microplate reader to assay the superoxide and hydroxyl radical scavenging activities improves the accuracy of data and enables the use of much smaller amounts of samples and/or reagents, with much simpler experimental procedure. Therefore, These methods appear to be suitable for screening of superoxide and hydroxyl radical scavenging activities in both the plant medicinal extracts and the isolated compounds.

Objectives : Diabetes mellitus is the leading cause for vascular complications such as atherosclerosis. The present study is to investigate whether Doinseunggi-tang (DST) improves diabetic vascular dysfunction in type II diabetes. Methods : The db/db mice were treated with high fat/high cholesterol diet and DST (200 mg/kg/day) for 8 weeks. Results : DST significantly lowered blood glucose and systolic blood pressure. In addition, DST also markedly decreased total plasma cholesterol, triglyceride, and LDL-cholesterol, whereas increased the HDL-cholesterol. Vascular relaxation of aortic rings by acetylcholine or SNP was ameliorated by DST in a dose-dependent manner. Damage of vascular intima and hypertrophic of media was improved by DST. Immunohistological study revealed that DST attenuated the increase of ICAM-1, VCAM-1, and ET-1 expression in thoracic aorta. Conclusions : Taken together, DST suppressed hyperglycemia and diabetic vascular dysfunction in type II db/db mice. The present data suggests that Doinseunggi-tang may be prevent a development of diabetic atherosclerosis.

옥수수는 세계 3대 작물 중 하나로 생산성이 높은 작물이다. 옥수수는 생육 기간이 짧아 국내 온난화 현상으로 온도가 높아진 남부지역에서는 2기작 재배가 가능하여 경쟁력이 있는 품목이다. 현재 국내에서 개발된 옥수수 수확기는 full-feed type의 트랙터 부착형 작업기로 트랙터 3점 히치부에 부착되며, 트랙터의 PTO로부터 동력을 전달받아 구동된다. 본 연구에서는 식용 옥수수(품종: Godangok)를 재배하는 필드에서 수확기를 사용하여 수확 작업 시 발생하는 실 부하 데이터를 계측하였다. 계측용 트랙터의 PTO 축에 토크 미터를 장착하여 수확 작업 시 토크와 회전속도를 계측하였다. 또한, 계측된 데이터를 이용하여 기어와 베어링에 작용하는 부하스펙트럼(load spectrum)은 하중 지속 분포(LDD: load duration distribution)방법으로 하중(load magnitude), 회전속도(speed), 시간 데이터(duration)를 도출하였고, 축과 하우징에 작용하는 부하스펙트럼은 레인플로우 카운팅(RFC: rainflow counting)방법으로 하중 진폭(load range), 평균 하중(mean load), 사이클수(no. of cycles)를 도출하였다.

클러스터 정보를 이용한 네트워크 이상상태 탐지방법

이호섭(Ho-sub Lee),박응기(Eung-ki Park),성정택(Jung-taek Seo) 한국정보보호학회 2012 정보보호학회논문지 Vol.22 No.3

최근 우리는 급격한 정보통신 기술의 발달로 큰 변화를 겼었으며, 기존의 기반 시설들 및 서비스들이 정보통신 기술과 융합되면서, 다시 한 번 환경 변화를 눈앞에 두고 있다. 정보통신의 발달은 이러한 이점들 외에도 여러 부작용을 낳고 있으며, 이러한 부작용들은 금전적 피해뿐만 아니라 국가적인 재난 상황으로 발전될 소지가 있다. 따라서 이들에 대한 탐지 및 신속한 대응이 중요하며, 이와 관련한 많은 시도가 이루어지고 있다. 이러한 예로는 침입탐지시스템이 있을 수 있다. 그러나 침입탐지시스템은 특정 트래픽이나, 파일이 악성인지 여부를 판단하는데 중점을 두고 있으며, 현재까지 변종이나 새롭게 개발된 악성 코드에 대한 탐지는 힘들다. 따라서 본 논문에서는 네트워크의 현재의 상황과 과거의 상황들을 비교하여, 현재 시점의 네트워크 모델이 정상인지 비정상인지를 판단 할 수 있는 방법에 대해 제안한다. The rapid development of information technology is making large changes in our lives today. Also the infrastructure and services are combinding with information technology which predicts another huge change in our environment. However, the development of information technology brings various types of side effects and these side effects not only cause financial loss but also can develop into a nationwide crisis. Therefore, the detection and quick reaction towards these side effects is critical and much research is being done. Intrusion detection systems can be an example of such research. However, intrusion detection systems mostly tend to focus on judging whether particular traffic or files are malicious or not. Also it is difficult for intrusion detection systems to detect newly developed malicious codes. Therefore, this paper proposes a method which determines whether the present network model is normal or abnormal by comparing it with past network situations.
