최근까지도 중소기업의 지속성장 및 경쟁력 확보에 대한 중요함을 인식함에 따라, 정부 차원에서의 유형 자원(R&D 인력, 자금 등)에 대한 지원이 주로 투입되어 왔다. 그러나 사업지원의 적절성이나 효과성, 효율성 면에서 서로 상충되는 정책부분이 존재하여 과소 지원이나 중복 지원 등 지원체계의 비효율성 문제가 제기되어온 것도 사실이다. 정부나 기업 관점에서는 중소기업의 한정된 자원으로 인해, 외부와의 협력을 통한 기술개발 및 역량강화가 기업의 경쟁우위를 창출하는 근간이라 보고 있으며, 이를 위한 가치창출 활동을 강조하고 있다. 기업 레벨에서의 지식생태계 구축을 통해 일련의 가치사슬로부터 기업거래 관계를 분석하고 결과를 가시화할 수 있는 밸류체인 네트워크 분석이 필요한 것도 이 때문이다. 특허/제품/기업명 검색을 통해 관련 제품의 정보나 특허 보유 기업의 기술(제품) 현황 정보를 제공하는 기술기회발굴시스템(Technology Opportunity Discovery system), 기업(재무)정보와 신용정보을 열람하게 해주는 CRETOP이나 KISLINE 등은 존재하고 있으나 밸류체인 네트워크 분석기반으로 유사(경쟁)기업의 리스트나 향후 거래 가능한 잠재 거래처 정보를 제공해주는 시스템은 부재한 실정이다. 따라서, 본 고에서는 KISTI에서 개발 운영중인 기업 비즈니스 전략수립 지원 파트너인 '밸류체인 네트워크 시스템(Value Chain Network System : VCNS)'을 중심으로, 탑재된 네트워크 기반 분석모듈의 유형, 이를 지원하는 참조정보 및 데이터베이스(D/B)의 구성 로직과 시스템 활용방안을 고찰하며, 산업구조를 이해하고 기업의 신제품 개발을 위한 핵심정보가 되고 있는 지능형 밸류체인 분석 시스템의 네트워크 가시화 기능을 살펴보기로 한다. 한 기업이 다른 기업 대비 경쟁우위를 확보하기 위해서는 보유 특허 또는 현재 생산하고 있는 제품에 대한 경쟁자 식별이 필요하며, 세부 업종별 유사(경쟁)기업을 탐색하는 일은 대상기업의 사업화 경쟁력 확보에 핵심이 된다. 또한 기업간 비즈니스 활동인 거래정보는 유사 분야로 진출할 경우 잠재 거래처 정보를 제공하는 중요한 역할을 수행한다. 이러한 기업간 판매정보를 기반으로 구축된 네트워크 맵을 활용하여 기업 또는 업종 수준의 경쟁자를 식별하는 일은 밸류체인 분석의 핵심모듈로 탑재될 수 있다. 밸류체인 네트워크 시스템(VCNS)은 단순 수집된 종래의 기업정보에 밸류체인(value chain) 및 산업구조 분석개념을 접목하여 개별 기업의 시장경쟁 상황은 물론 특정 산업의 가치사슬 관계를 파악할 수 있다. 특히 업종구조 파악, 경쟁사 동향 파악, 경쟁사 분석, 판매처 및 구매처 발굴, 품목별 산업동향, 유망 품목 발굴, 신규 진입기업 발굴, VC별 핵심기업 및 품목 도출, 해당 기업별 보유 특허 파악 등 기업 레벨에서의 유용한 정보분석 툴로 활용 가능하다. 또한, 거래처 정보 및 재무데이터로부터 분석된 결과의 객관성 및 신뢰성을 기반으로, 현재 국내에서 이용 중인 15,000여개 회원기업과 연구개발서비스업 종사자, 출연(연) 및 공공기관 등에서 사업평가 정보지원, R&D 의사결정 지원 및 중 단기 수요예측 전망 등 다양한 목적(용도)에 밸류체인 네트워크 시스템을 활용할 수 있을 것으로 기대된다. 기업의 사업경쟁력 강화를 위해 정부기관 및 민간 연구개발서비스 기업을 중심으로 기술(특허) 및 시장정보가 제공되어 왔으며, 이는 특허분석(등급, 계량분석 위주) 또는 시장분석(시장보고서 기반 시장규모 및 수요예측 위주)의 형태로 지원되어 왔다. 그러나 기업이 사업화진출 단계에서 겪게 되는 애로요인의 하나인 정보부족을 해결하는데 한계가 있었으며, 특히 경쟁기업 및 거래가능 기업 후보군에 대한 탐색정보는 입수하기 어려웠다. 본 연구를 통해 제안된 네트워크맵 및 보유 데이터 기반의 실시간 밸류체인 가시화 서비스모듈이 중견 중소기업이 당면한 신규시장 진출시 경쟁기업 대비 예상점유율, (예상)매출액 수준, 어느 기업을 컨택하여 유통망(원자재/부품에 대한 공급처, 완제품/모듈에 대한 수요처)을 확보할 지에 대한 핵심정보를 제공할 수 있을 것으로 기대된다. 향후 연구에서는 대체기업(또는 대체품목) 경쟁지표의 개발과 연구주체의 참여를 통한 경쟁요인별 지표의 고도화 연구, VCNS의 성능향상을 위한 데이터마이닝 기술 및 알고리즘을 추가 반영하도록 수행하고자 한다.
본 연구는 가맹사업자의 자기효능감에 주목하여 정부가 예비가맹사업자들을 보호하기 위해 가맹본부에 다양한 규제와 정책을 사용하는 것이 최선의 방법이 아니라는 것에 관심을 두고 있다. 본 연구에서는 경로-목표이론(path-goal theory)에서 제시한 가맹본부의 리더십 행동 유형과 가맹사업자의 관계결속의 영향관계에 있어서 가맹사업자의 특성으로 자기효능감의 조절효과를 규명하고, 실증 분석한 결과 다음과 같은 연구의 시사점을 발견할 수 있었다. 첫째, 가맹본부의 리더십 행동유형이 관계결속에 긍정적 효과를 가져 온다는 사실이 확인됨으로써 가맹본부는 가맹사업자에게 맞는 리더십 행동유형을 적용할 수 있도록 하여야 한다. 둘째, 가맹사업자의 자기효능감이 관계결속에 긍정적 효과가 있을 뿐만 아니라, 리더십 행동유형과 관계결속 사이에 상당한 조절효과가 있기 때문에 가맹본부는 가맹사업자들의 개인차(individual difference) 관리가 필요하다. 셋째, 정부는 가맹본부를 규제할 것만이 아니라 가맹본부가 가맹사업자들의 특성을 확실하게 파악하고 기업의 목표달성을 위한 정당한 통제가 가능하도록 제도적 지원을 해야 할 것이다.
A costume reveals the social characteristics of the era in which it is worn, thus we can say that the history of change of the costume is the history of change of the living culture of the era. Since the Three States era, the costume structure of this country had been affected by the costume system of the China's historical dynasties in the form of the grant therefrom because of geographical conditions, which affection was conspicuous for the bureaucrat class, particularly including but not limited to the Kings' familities. Such a grant of the costume for the bureaucrat class (i.e., official uniform) was first given by the Dang-dynasty at the age of Queen Jinduck, the 28th of the Shilla-dynasty. Since then, the costume for the bureaucrats had consecutively been affected as the ages had gone from the unified Shilla, to the Koryo and to the Yi-dynasty. As the full costumes officially used by government officials (generally called "Baek Gwan") in the Yidynasty, there existed Jo-bok, Gong-bok and Sang-bok. Of such official costumes, Gong-bok was worn at the time of conducting official affairs of the dynasty, making a respectful visit for the expression of thanks or meeting diplomatic missions of foreign countries. It appears no study was made yet with regard to the Gong-bok while the studies on the Jo-bok and the Sangbok were made. Therefore, this article is, by rendering a study and research on the styles of costumes of civil servants' stone images erected at the Kings' tombs of the Yi-dynasty, to help the persons concerned understand the Gong-bok, one of the official costume for Baek Kwan of that age and further purports to specifically identify the styles and changes of the Gong-bok, worn by Baek Gwan during the Yi-dynasty, consisting of the Bok-doo (a hat, four angled and two storied with flat top), Po (gown), Dae (belt), and Hol (small and thin plate which was officially held by the government officials in hand, showing the courtesy to and writing brief memorandums before the King) and Hwa (shoes). For that purpose, I investigated by actually visiting the tombs of the Kings of the Yi-dynasty including the Geonwon-neung, the tomb of the first King Tae-jo and the You-neung, the tomb of the 27th King Soon-jong as well as the tombs of the lawful wives and concubines of various Kings, totalling 29 tombs and made reference to relevant books and records. Pursuant. to this study, of the 29 Kings' tombs the costume styles of civil servants' stone images erected at the 26 Kings' tombs are those of Gong-bok for Baek-gwan of the Yi-dynasty wearing Bok-doo as a hat and Ban-ryeong or Dan-ryenog Po as a gown with Dae, holding Hol in hand and wearing shoes. Other than those of the 26 tombs, the costume styles of the Ryu-neung, the tomb of the Moon-jo who was the first son of 23rd King Soon-jo and given the King's title after he died and of the You-neung, the tomb of the 27th King Soon-jong are those of Jobok with Yang-gwan (a sort of hat having stripes erected, which is different from the Bok-doo), and that of the Hong-neung, the tomb of the 26th King Go-jong shows an exceptional one wearing Yang-gwan and Ban-ryeong Po ; these costume styles other than Gongbok remain as the subject for further study. Gong-bok which is the costume style of civil servants' stone images of most of the Kings' tombs had not been changed in its basic structure for about 500 years of the Yi-dynasty and Koryo categorized by the class of officials pursuant to the color of Po and materials of Dae and Hol. Summary of this costume style follows: (1) Gwan-mo (hat). The Gwan-mo style of civil servants' stone images of the 26 Kings' tombs, other than Ryu-neung, Hong-neung and You-neung which have Yang-gwan, out of the 29 Kings' tombs of the Yi-dynasty reveals the Bok-doo with four angled top, having fore-part and back-part divided. Back part of the Bok-doo is double the fore-part in height. The expression of the Gak (wings of the Bokdoo) varies: the Gyo-gak Bok-doo in that the Gaks, roundly arisen to the direction of the top, are clossed each other (tombs of the Kings Tae-jong), the downward style Jeon-gak Bok-doo in that soft Gaks are hanged on the shoulders (tombs of the Kings Joong-jong and Seong-jong) and another types of Jeon-gak Bok-doo having Gaks which arearisen steeply or roundly to the direction of top and the end of which are treated in a rounded or straight line form. At the lower edge one protrusive line distinctly reveals. Exceptionally, there reveals 11 Yang-gwan (gwan having 11 stripes erected) at the Ryu-neung of the King Moon-jo, 9 Yang-gwan at the Hong-neung of the King Go-jong and 11 Yang-gwan at the You-neung of the King Soon-jong; noting that the Yang-gwan of Baek Kwan, granted by the Myeong-dynasty of the China during the Yi-dynasty, was in the shape of 5 Yang-gwan for the first Poom (class) based on the principle of "Yideung Chaegang" (gradual degrading for secondary level), the above-mentioned Yang-gwans are very contrary to the principle and I do not touch such issue in this study, leaving for further study. (2) Po (gown). (a) Git (collar). Collar style of Po was the Ban-ryeong (round collar) having small neck-line in the early stage and was changed to the Dan-ryeong (round collar having deep neck-line) in the middle of the: dynasty. In the Dan-ryeong style of the middle era (shown at the tomb of the King Young-jo); a, thin line such as bias is shown around the internal side edge and the width of collar became wide a little. It is particularly noted that the Ryu-neung established in the middle stage and the You-neung in the later stage show civil servants in Jo-bok with the the Jikryeong (straight collar) Po and in case of the Hong-neung, the Hong-neung, the tomb of the King Go-jong, civil servants, although they wear Yang-gwan, are in the Ban-ryeong Po with Hoo-soo (back embroidery) and Dae and wear shoes as used in the Jo-bok style. As I could not make clear the theoretical basis of why the civil servants' costume styles revealed, at these tombs of the Kings are different from those of other tombs, I left this issue for further study. It is also noted that all the civil servants' stone images show the shape of triangled collar which is revealed over the Godae-git of Po. This triangled collar, I believe, would be the collar of the Cheomri which was worn in the middle of the Po and the underwear, (b) Sleeve. The sleeve was in the Gwan-soo (wide sleeve) style. having the width of over 100 centimeter from the early stage to the later stage arid in the Doo-ri sleeve style having the edge slightly rounded and we can recognize that it was the long sleeve in view of block fold shaped protrusive line, expressed on the arms. At the age of the King Young-jo, the sleeve-end became slightly narrow and as a result, the lower line of the sleeve were shaped curved. We can see another shape of narrow sleeve inside the wide sleeve-end, which should be the sleeve of the Cheom-ri worn under the Gong-bok. (c) Moo. The Moo revealed on the Po of civil servants' stone images at the age of the King Sook-jong' coming to the middle era. Initially the top of the Moo was expressed flat but the Moo was gradually changed to the triangled shape with the acute top. In certain cases, top or lower part of the Moo are not reveald because of wear and tear. (d) Yeomim. Yeomim (folding) of the Po was first expressed on civil servants' stone images of the Won-neung, the tomb of the King Young-jo and we can seemore delicate expression of the Yeomim and Goreum (stripe folding and fixing the lapel of the Po) at the tomb of the Jeongseong-wanghoo, the wife of the King Young-jo, At the age of the King Soon-jo, we can see the shape of Goreum similar to a string rather than the Goreum and the upper part of the Goreum which fixes Yeomim was expressed on the right sleeve. (3) Dae. Dae fixed on the Po was placed half of the length of Po from the shoulders in the early stage. Thereafter, at the age of the King Hyeon-jong it was shown on the slightly upper part. placed around one third of the length of Po. With regard to the design of Dae, all the civil servants' stone images of the Kings' tombs other than those of the Geonwon-neung of the King Tae-jo show single or double protrusive line expressed at the edge of Dae and in the middle of such lines, cloud pattern, dangcho (a grass) pattern, chrysanthemum pattern or other various types of flowery patterns were designed. Remaining portion of the waist Dae was hanged up on the back, which was initially expressed as directed from the left to the right but thereafter expressed. without orderly fashion,. to the direction of the left from the right and vice versa, Dae was in the shape of Yaja Dae. In this regard, an issue of when or where such a disorderly fashion of the direction of the remaining portion of waist Dae was originated is also presented to be clarified. In case of the Ryuneung, Hong-neung and You-neung which have civil servants' stone images wearing exceptional costume (Jo-bok), waist Dae of the Ryu-neung and Hong-neung are designed in the mixture of dual cranes pattern, cosecutive beaded pattern and chrvsenthemum pattern and that of You-neung is designed in cloud pattern. (4) Hol. Although materials of the Hol held in hand of civil servants' stone images are not identifiable, those should be the ivory Hol as all the Baek Gwan's erected as stone images should be high class officials. In the styles, no significant changes were found, however the Hol's expressed on civil servants' stone images of the Yi-dynasty were shaped in round top and angled bottom or round top and bottom. Parcicularly, at the age of the King Young-jo the Hol was expressed in the peculiar type with four angles all cut off. (5) Hwa (shoes). As the shoes expressed on civil servants' stone images are covered with the lower edges of the Po, the styles thereof are not exactly identifiable. However, reading the statement "black leather shoes for the first class (1 Poom) to ninth class (9 Poom)," recorded in the Gyeongkook Daejon, we can believe that the shoes were worn. As the age went on, the front tips of the shoes were soared and particularly, at the Hong-neung of the King Go-jong the shoes were obviously expressed with modern sense as the country were civilized.
The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times. C-DAK 4000 (Cordis Dow) and CF IS-11 (Baxter Travenol) reused dialyzers obtained from the dialysis clinic were used in the present study. The new dialyzers exhibited a relatively flat APD, whereas saline rinsed and reused dialyzers showed considerable amount of decay. C-DAH dialyzers had a larger APD(11.70
