국내 프라이빗 뱅킹시장은 2000년 들어서 본격적으로 도입되기 시작했으며, 2004년 이후 주식시장이 크게 상승하면서 각광 받기 시작했다. 국내 금융기관들은 프라이빗 뱅킹을 도입하면서 각 금융기관에 맞는 차별화된 서비스를 제공하고자 노력하였지만, 브랜드 인지도 강화, 영업점과 판매상품의 차별화, 전문인력 양성 등 소프트적 노력의 다소 부족하였다. 2007년 미국을 시발로 전 세계에 금융위기가 발생하여, 프라이빗 뱅킹 시장에 큰 변화를 주고 있다. 국내 프라이빗 뱅킹 금융기관들은 지속적인 점포 확대 등 투자확대를 추구하였으나, 금융위기에 대한 슬기롭지 못한 대처로 프라이빗 뱅킹 고객들이 현금성 자산을 증대시키는 등 보수적인 포트폴리오로 전환하여 수수료 수입의 급감하여 수익성이 급격히 나빠졌다. 비밀유지를 업의 개념으로 하는 프라이빗 뱅킹 금융기관과 프라이빗 뱅킹 고객의 특성으로 금융기관 내부적으로 자료를 보유하고 관리하여 프라이빗 뱅킹 시장에 대한 연구가 진행되기 어려워서 국내 프라이빗 뱅킹에 대한 연구가 미진했던 것이 현실이다. 최근에 소매금융시장에서 많은 발전이 예상되는 PB시장에 대한 관심으로 PB시장에 대한 연구가 증가 일로에 있는 것이 다행한 일이다. 다만, PB사업은 고객과의 좋은 관계 유지가 관건인데, 이 분야에 대한 연구가 아직까지 미천한 실적을 보이고 있다. PB고객에게 서비스만족도를 높이게 되면, 큰 비용 들이지 않고 기존 PB고객의 자산증대 및 신규 PB고객을 소개받을 수 있고, 저비용 고효율의 마케팅이 가능하다. 궁극적으로는 저비용과 고수익으로 금융회사의 손익개선과 수익선 다변화에 좋은 영향을 미칠 것이다. 따라서 PB사업에서 고객만족을 통한 충성도 제고는 고객유치 자산증대, 고객기반 확보, 주변 부자소개 등으로 PB사업의 성패가 달려 있다 해도 과언이 아니다. 본 논문에서는 잘 알려지지 않은 프라이빗 뱅킹 시장에 대한 고찰과 프라이빗 뱅킹 고객 서비스 품질에 대한 이론적 연구를 진행하였다. 특히 고객 니즈와 만족을 통한 충성도 제고에 대한 끊임없는 연구가 필요한데, 고객 충성도에 긍정적 영향을 주는 고객 지향성과 서비스 만족도, 신뢰성의 중요성을 인식하고 하부요인들의 연구를 통해서 소매금융의 핵심인 프라이빗 뱅킹시장 발전에 조금이나마 이바지하고자 한다. 주제어: 프라이빗 뱅킹, 서비스품질, 서비스만족, 고객신뢰, 고객충성도 The private banking biz was introduced in the domestic financial market after 2000 that has been developing with stock market. Although domestic financial institutions have been trying to provide differentiated services to the high net worth individuals(HNWIs) based on their strengths, it turned out to need more sort-ware efforts such as improving the brand image, differentiating sales networks and developing tailor-made financial products, and educating private bankers. The financial crisis from the U.S. had a bad effect on international private baking biz after 2007, and the revenues and profits of the domestic private baking biz decreased quickly. Due to the late timing of portfolio change during the financial crisis period, while increasing investment such as opening new branches for private banking, HNWIs have been changing their portfolios from investment accounts to low profitable cash accounts. As a result, the revenues and profits of financial institutions have been falling down sequentially. Recently, some studies have been increased in private banking area because the private banking has been rapidly increasing the market share in the retail banking area. Although the studies for the private banking have been increasing, more studies are needed for studying the relationship with private banking clients, which is very important in the private banking biz. The higher service quality makes the higher satisfaction and trust that can increase asset gatherings of current clients and introduce new comers by good references of current clients. That is, financial institutions can have lower cost of marketing and more fruitful results efficiently. On this study, we reviewed prior studies of the service quality, the customer satisfaction, and the clients' loyalty. Based on the results of these studies, we derived several hypotheses to be tested through the clients interview survey. We hope this study can be helpful for the development of the private banking business. Keywords: Private Banking, Service Quality, Customer Satisfaction, Trust, Loyalty

To satisfy the increasing needs for blood transfusion it is necessary not only to find new blood donors but also to repeat the collection of blood from the same donors. It was recognized that too frequent blood donations might become detrimental to the health of the donor, above all in female donors in foreign countries where the blood program relies on voluntary donation. Unfortunately, the sources of much blood depends solely on professional donors except in a few instances in Korea. Thus, anemia of professional donors after repeated blood donation must be controlled. For this purpose, we studied hemoglobin levels and serum iron levels of professional donors, coming to Korean Red Cross Blood Service and Seoul Medical College Hospital. The data obtained in this study were as follows: (1) 6. 0% of male professional donors and 17.98% of female professional donors were disqualified owing to a low hemoglobin levels. On the other heand, only 0.8% of male voluntary donors and 10.6% of female voluntary donors were rejected. (2) 7.3% of male donors and 33.3% of female donors were rejected their donations because of low hemoglobin levels on their 5-6th visits. (3) The serum iron levels appeared to be decreased after repeated blood donations. Specially, serum iron levels of female donors decreased to 73. 6 mcg. /d. after 2-4 blood donations yearly. So, it might be recommended to limit the frequency of blood donations from female.

화학적 폐 손상시 폐 상피세포 장벽의 특성

The alveolar epithelial barrier permits only restricted passage of solutes, exemplified by a high resistance and equivalent pore properties similar to those of other tight biological barriers. These passive barrier properties may be markedly altered after insults to the lung, perhaps providing insights into the mechanisms of alveolar epithelial injury. The normally tight alveolar epithelium serves as an effective barrier against the leak of solutes from interstitial and vascular spaces into alveolar spaces, thereby helping to maintain the normal "dry" environment required for efficient gas exchange. Until recently, the majority of investigations of alveolar fluid balance relied on intact lung models. The information obtained from these intact mammalian lung studies in vivo and in vitro, if useful, can be difficult to interpret mechanistically, largely because of the anatomical complexity of the lung. For more precise information about alveolar epithelial properties, studies of isolated preparations have been done, providing useful additional approaches to underlying transport machanisms and pathways in the alveolar-capillary wall. In this review article, I introduced the methods being used for study of barrier function in addition to intact lung investigation. And I discussed the barrier properties of the alveolar epithelium relevant to alveolar fluid balance in chemically injured lung, citing the pertinent supporting experimental data where appropriate.

화학적 폐 손상시 상피세포 장벽의 특성

폐 상피세포 장벽은 다른 tight한 생체세포의 장벽에서와 마찬가지로 높은 조직저항을 보이며, 따라서 용매와 용질의 이동을 극히 제한한다. 이러한 수동적인 장벽의 특성은 폐의 여러조건에 의하여 심하게 변할 수 있으며 요즈음 폐 상피세포 손상의 장애시 그 기전이 활발하게 연구되고 있다. 정상적인 tight 한 폐 상피세포 장벽은 간질액과 혈관내로 부터 용질이 빠져 나오는 것을 막음으로써 폐의 일차적인 기본 기능인 기체교환을 하는데 있어 정상적으로 폐표면을 항상 건조하게 유지시킬 수 있는 것이다. 그러나 현재까지의 결과는 거의 모두가 작은실험 동물들의 전체 폐를 이용한 것으로 그 기전을 알기가 어렵고, 인체의 폐 상피세포에서의 물질이동에 대한 특성은 거의 알려진 바가 없다. 화학물질에 의한 인체 폐 부종의 기전을 알기 위하여 여러 실험 모델에서 얻은 결과를 통하여 추후 진단 및 그 자료 방침을 정할 수 있게 될 것으로 생각된다.

연산증폭기의 능동보상의 한 방안

李英姬,金允溟,林德奎 단국대학교 1984 論文集 Vol.18 No.-

Because the operational amplifiers have finite gain-bandwidth, sometimes they need frequency compensation. Soliman and Ismail suggested a method of active compensations. They made use of dual operational amplifiers. One of dual amplifiers is operated as a main amplifier and another is operated as a feedback element. Soliman and Ismail fixed the poles of the both amplifers the same. But the gain characteristics are not flat enough by this method. In this paper, detail analysis of their method is presented, and the reason why it has such defects is explained. A generalized method is suggested to ameliorate the gain to phase characteristics. Varying the pole location of a feedback amplifier, we were able to acquire proper gain or phase compensntion. Experimental results and computer calculations make good agreements.

Cellulose acetate electrophoretic studies of renal diseases were performed and the following results were obtained : 1) The mean values for the electrophoretic fractions of serum protein in nephrotic syndrome were 1.18±0.48gm/100㎖(28.65±8.03%), 0.25±0.19gm/100㎖(5.05±3.17%)1.46±0.57gm/100㎖(35.95±12.83%), 0.72±0.28gm/100㎖(17.32±5.39%), and 0.56±0.21gm/100㎖(13.45±4.47%), respectively, for the albumi, a₁-, a₂-, β-, and r- globulin fractions. It was found that decrensed both albumin 2.11 gm/100㎖(19a17%), and r-globulin, 0.94gm/100.㎖(7. 83%), fractions were more marked than in control groups. While α₂-globlllin fraction was markedly increased, 0.7gm/100㎖(25.37%), to compare in control group. 2) The correlation coefficient between albumin and α₂-globulin fractions in nephrotic syndrome was r= -0.84 and regression equation was y= -1.34x+74.40. 3) The A/G ratio was markedly reversed as 0.40±0.16. 4) The mean values for the electrophoretic fractions of serum proteins in nonnephrotic syndrome, i. e., acute and chronic glomerulonephritis, renal failure, pyelonephritis, and renal stones, were 2.35±0.59gm/100㎖(40.74±8.54%), 0.27±0.13gm/100㎖(4.65±1.98%), 0.78±0.25gm/100㎖(13.30±2.84%), 0.93±0.28gm/100㎖(15.75±4.33%), and 1.43±0.58gm/100㎖(24.14±8.14%), respectively, for the albumin, a₁-, a₂-, β-, and r-globulin fractions. It was found that decreased albumin and increased α₁--globulin fractions were marked than in control group. 5) In the biochemical data in nephrotic syndrome it was found that serum cholesterol was increased 2.5 times than in control group. In non-nephrotic syndrome group it was found that increased concentration of serum K and markedly increased concentration of serum creatinine(4.5 times) and BUN(3 times) were shown.

Evolution of Internal Waves Near a Turning Point in the South China Sea using SAR Imagery and Numerical Models

Duk Jin Kim,David R. Lyzenga,Woo Young Choi,Youn Soo Kim 大韓遠隔探査學會 2007 大韓遠隔探査學會誌 Vol.23 No.5

Subsurface Internal Waves (IWs) can be detected in satellite images as periodic alternating brighter/darker stripes. It is known that there are two types of IWs-depression type and elevation type-depending on the water depth in stratified oceans. In this study, we have quantitatively verified the process of converting polarity from depression waves to elevation waves using ERS-2 SAR image acquired over the northern South China Sea. We simulated the evolution of IWs near a turning point with a numerical model for internal wave propagation. The simulation results near the turning point clearly showed us not only a conversion process of IWs from depression to elevation waves, but also a similar wave pattern with the observed SAR image. We also simulated SAR intensity variation near the turning point. The upper layer currents were computed at regular intervals using the numerical model, as the IWs were passing through the turning point. Then, an integrated hydrodynamic-electromagnetic model was used for simulating SAR intensity profiles from the upper layer currents. The simulated SAR intensity profiles were compared with the observed SAR intensities.
