Park, Woon-Yong,Song, Youn-Kyung,Bae, Kyung-Ho,Kim, Yong-Suk 東亞大學校 建設技術硏究所 2005 硏究論文集 Vol.28 No.2

Currently, digital maps in the metropolitan area are supposed to be revised and renewed every two years, but it is difficulty for the renewal of current information to keep pace with the quickly changing society and so, one of the alternative methods being discussed is a digital map produced using high resolution satellites. The biggest problem in the production of digital maps using high resolution satellite images is the difficulty of production in vector resource format through edge detection of satellite images, a Raster data. In this study, topographical boundaries were detected through edge detection of the satellite image, and after vectorliezing using the screen digitizing method, the results were evaluated and compared to the digital map from the NGII(National Geographic Information Institute) for accuracy.

셈어의 발달과 분화에 관한 연구 : 아랍어를 중심으로 Centering around the Arabic Language

윤용수 부산외국어대학교 지중해연구소 2002 지중해지역연구 Vol.4 No.2

The Semitic language family has the longest recorded history of any linguistic group. The Akkadian language is first attested in cuneiform writing on clay tablets from ancient Mesopotamia (modern Iraq) from the mid-third millennium B.C. and Semitic languages continue to be spoken in the Middle East and in northeastern Africa today. But, lacking of the written materials and systematic research about Semitic languages, a study on the development and diversification of semitic languages is still the beginning stage in Korea. Also, Almost nothing have been carried a study on relationship of the ancient kingdoms to their languages in Arabic Peninsular. In this article, I deal the development and diversification of semitic languages centering around Arabic language. I expect that this research will be the Arabic historical linguistics in the Arabia Peninsula.

複素變數函數의 寫像에 對한 考察

尹榮重 大田工業高等專門學校 1971 論文集 Vol.8 No.-

Gauss achieved a great success in showing the algebric theorem, which has the epoch-making importance in the history of mathematics, by using the complex number. Cauchy, using a complex number, developed his theory of function and solved many doubtful problems in differential and integral calculus. According to the development of the projective geometry, it has been made certain that the elements of an imaginary quantity must be used in geometry, too. Therefore, it is very unnatural and inconvenient that we should think every problem in the scope of an actual number. The harmonic and integral development of mathematics is possible only in the scope of a complex number and we'd be able to clarify the deep qualities of mathematics by thinking about a function of the complex number. I dare say that the mathematics of today is that of a complex number. So widely is used a complex number in every field. Now, I'd like to think about the representation of the linear function among the qualities of a complex number.

소뇌에 발생한 과립구성 육종 : 증례보고

윤승환,변진수,홍순기,김헌주,한용표,양재승,조미연 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.8

Granulocytic sarcoma, a rare extramedullary solid tumor arising from early myeloid precursors, is capable of invading the meninges or the brain parenchyma. The tumor may occur during or after the onset of systemic myelogenous leukemia. On rare occasions, the tumor may evolve before the onset of systemic myelogenous leukemia. Children are affected more often than adults, but sex is not related. Although no definite target area of the brain can be demonstrated, there may be some predilection of the tumor for the posterior fossa. The authors report a case of 4-year-old-boy with granulocytic sarcoma occuring in the posterior fossa presenting with gait disturbance and torticollis. The patient was treated by surgical removal of the tumor, thereby avoiding the potentially lethal complication of a posterior fassa mass. This rare case is reported together a review of the literature.

윤선주,김경은,정용진 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2003 한국식품저장유통학회지 Vol.10 No.3

반응표면분석법을 이용하여 음료의 제조조건에 따른 늙은 호박의 품질 특성을 모니터링하고 음료 배합비를 설정하였다. 제조조건에 따른 음료의 색상, 향, 맛, 조직감과 전반적인 기호도를 희귀분석한 결과, R^(2)는 각각 0.7682, 0.9046, 0.9364, 0.9110, 0.8765이었고 pH, brix 그리고 점도에 대한 R^(2)는 0.9264, 0.7135, 0.9906으로 나타났으며 색상과 brix를 제외한 다른 품질에서는 5~10%이내의 수준에서 유의성이 인정되었다. 호박 음료의 품질에 대한 영향에서는 호박 추출액 함량이 가장 영향을 받았으며 다음으로 진탄검 함량 마지막으로 식초 함량인 것으로 나타났다. 호박 파우치 음료 제조의 최적 배합비 범위를 얻기 위해 유의성이 인정된 향, 맛, 조직감, 전반적인 기호도 그리고 점도 등의 contour map을 superimposing한 결과, 호박 추출액 함량 86.5~87.5%, 잔틴검 함량 0.36~0.42%, 식초 함량 9%로 예측되었다. In the present study, we investigated the optimum recipe of the pumpkin drink using old pumpkin extract. Response surface methodology (RSM) was applied to optimize and monitor the drink recipe with pumpkin extract. The polynomial equation for color, flavor, taste, mouth feel, overall palatability, pH, brix and viscometer showed 0.7682, 0.9046, 0.9364, 0.9110, 0.8456, 0.9264, 0.7135 and 0.9906 of R^(2), respectively and flavor, taste, mouth feel, overall palatability, pH and viscometer showed 5∼10% of significance level. The optimum ranges of recipe on organoleptic properties of pumpkin pouch drink were estimated on 86.5∼87.5% of the old pumpkin extract, 0.36∼0.42% of xanthan gum and 9% of vinegar.

Private Banking 분석 및 PB서비스품질에 관한 연구

원연식, 김용덕 숭실대학교 2009 숭실경영연구 Vol.1 No.1

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

이슬람의 규범과 예절

윤용수 부산외국어대학교 지중해연구소 2003 지중해지역연구 Vol.5 No.2

All of the societies in the earth have developed their own norms to keep and regulate the conduct of personal and social relations. This norms reflect the character, value and experience of the each society. Every people in the society must observed it's own rules and norms. In islamic society, it is true that many elements of islamic norms and manners still dominate various spheres of daily life. Expecially, The Quran and Hadith have influenced absolutely the muslims' life. And it is also true that the foreign elements have had a wide and increasing influences in islamic world. Therefore we can found the coexistence of the islamic elements and the foreign one in Arab-muslim society. To understand islamic society, it is natural that we have to know the above mentioned characters and muslim's way of thinking and pattern of life. In this article, I try to introduce the characters of islamic society and it's norms and manners to understand islamic world.

효소제 처리에 따른 늙은 호박의 추출 특성

윤선주,김경은,정용진 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2003 한국식품저장유통학회지 Vol.10 No.3

본 연구에서는 늙은 호박의 효소처리 조건에 따른 추출특성을 조사하였다. 그 결과, pectinase에 의한 영향에서는 효소제 처리를 한 모든 구가 대조구보다 품질 특성이 우수하였으며, 특히 0.15%(w/w) pectinase 처리구의 품질특성이 가장 높게 분석되었다. 혼합 효소제 처리에서는 pectinase와 celluase의 단독 처리구에 비해 pectinase와 celluase의 혼합효소제의 추출율이 높게 나타났다. 최적 효소제 처리조건 실정을 위한 늙은 호박의 추출조건(Ⅰ~Ⅳ)에서 추출물의 수율은 pectinase와 celluase를 혼합 처리한 구(Ⅲ)에서 86.04%로 가장 높게 나타났으며, 가용성 고형분 및 pH는 모든 처리구에서 비슷한 경향을 보였다. 환원당과 전당 함량은 각각 2.81, 4.60%로 나타난 효소제 혼합 처리구(Ⅲ)가 높았으며 total carotene은 pectinase 처리구가 5.36㎎%로 높은 함량을 나타내었다. 모든 처리구에 대한 아질산염소거능 결과는 pH6.0을 제외한 pH 1.2, 3.0, 4.0에서 소거능이 있는 것으로 나타났고 유리 아미노산 분석에서는 총 함량이 176.85, 171.89㎎%인 Ⅲ, Ⅳ 처리구가 무처리구에 비해 높은 함량으로 분석되었으며 citrulline은 Ⅰ, Ⅳ 처리구에서는 분석되지 않았으나 ⅡⅢ 처리구에서는 1.61, 1.41㎎%로 분석되었다. 이상의 결과로 늙은 호박의 추출조건으로는 무처리구보다는 효소제를 처리한 구에서 높은 수율 및 품질의 우수성이 인증되었으며 그 중 Ⅲ 처리구인 pectinase와 cellulase(0.15:0.05, %)를 혼합하여 추출함으로써 추출율 및 품질특성이 우수한 추출물을 얻을 수 있을 것으로 생각된다. In the present study, we investigated the quality characteristic of old pumpkin extract treated with enzymes. As a results, all the groups treated with pectinase were better in quality characteristic than control group and the group treated with 0.15%(w/w) pectinase was specially great. All the groups treated with simultaneous pectinase and cellulase were higher in the extraction rate than the groups treated with pectinase or cellulase. The experimental groups were divided into non-treated control(Ⅰ) and three treatment groups(Ⅱ-Ⅳ) for optimum condition of enzyme treatment. The Ⅱ and Ⅳ groups were treated with 0.15%(w/w) pectinase and 0.15%(w/w) cellulase, respectively, and Ⅲ group was treated with both 0.15%(w/w) petinase and 0.05%(w/w) cellulase. Yield for old pumpkin extract of the Ⅲ group (86.94%) was higher than that of other groups, but there were no significant difference among the groups in soluble solide content and pH of the extract. Reducing sugar and total sugar contents in the Ⅲ group were 2.81% and 4.60%, espectively. Total carotene content in the Ⅱ group (5.36㎎%) was higher than other groups. Old pumpkin extracts in all the groups showed nitrite-scavenging ability to pH 1.2, 3.0 and 4.0. Total free amino acid content in the Ⅲ group (176.7㎎%) was higher than other groups. Citrulline contents in the Ⅱ and Ⅲ groups were detected 1.66 and 1.41 ㎎%, respectively but the contents in other groups were not detected.

두부손상시 발견된 뇌혈관질환

윤승환,변진수,홍순기,김헌주,한용표 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.10

Five separate incidences of patients with cerebrovascular disease(CVD) were revealed among 555 craniocerebral traumatic victims between 1991 and 1992. The 5 cases of with cerebrovascular disease revealed included 3 aneuryms. 1 arteriovenous malformation and 1 spontaneous intracerebral hematoma caused by angiographic study. The frequent use of computerized tomographic scans in the evaluation of head-injured victims can well demonstrate an intracerebral hemmorrhage, but may not get able to direct the associated cerebrovascular disease;whereas the efficacy of angiography, on the contrary, has been losing its popularity as diagnostic armamentarium. The importance of angiographic study should be considered, if clinical signs and/or brain CT ideate the possibility of cerebrovasular disease even during the course of head injury management.
