        朝鮮後期 逆謀事件과 宦官의 內應

        장희홍(Jang Hee-heung) 역사실학회 2006 역사와실학 Vol.29 No.-

        It was said that many of the treasonable plot concerned the eunuch took place frequently and changed the political climate in the lately Chosun Dynasty period. During the reign period between the king Kwanghaegun(光海君) to Injo(仁祖), these events got mixed with the trouble of the succession of king. The times of king Sukjong(肅宗)’ s was the political struggle years between Southerners(南人) and Westerners(西人). It was the changeful period from Gyongjong(景宗) to Yeongjo(英祖) that the Noron party(老論) came to the power and the Soron party(小論) responded to the Noron party in the meanwhile. All the before and after of the enthronement of Jeonjo(正祖), since when the Noron party took the political leadership. It seemed to me that the eunuch took part in the political change course because they was likely to look around the king nearly. They did not control the affairs of state by themselves but were needed inevitably by the ambitious court officials for the access or the turnover of political power. Those officials could remove the kings of the generation in Chosun Dynasty by killing or poisoning through the eunuch and the court lady who serviced on the king at the most closed palace. As time go by, the function of the eunuch and the court lady was changed. The eunuch played the middle part of treasonable affairs with the court lady in the reign of king Kwanghaegun and Injo Especially each case of Min Hee-gun(閔希騫) or Bae Hee-do(裵希度) was not the prime mover’s case. Each of eunuch concerned of their case was the assistant whom the prime mover entice to kill the king at Court. Either case of Park Sang-gum(朴尙儉) or Chang Sea Gil(張世相), however, was transformed into the prime mover s cases. As is remarked above, when the bureaucratic group and the maternal relative group of King continued to attempt to seize the political power, their groups formed friendly relations with the eunuch and the court lady properly for the a treasonable plot and by their needs. For this reason, the eunuch and the court lady had consider influence upon the political transformation in the latter period of Chosun Dynasty.

      • Effects of Chitosan Intake on Bone Mass, Bone Related Metabolic Markers in Ovariectomized Rats

        Jang, Ye Sun,Lee, Myoung Hee 제주관광대학 2005 論文集 Vol.11 No.-

        In the present study we examined both the etiology of bone loss induced by dietary chitosan and the preventive effect of vitamin C supplementation. Rats were OVX and maintained on one of the following diets for 4 weeks: 10% cellulose (CE), 10% chitosan (CH) and 10% chitosan with sodium ascorbate (CHVC). Vitamin C supplementation to CH caused an increase in Ca and P contents of femurs as well as BMD of L4, with a decrease in urinary Ca excretion. There was no significant difference in intestinal Ca absorption between CH and CE, whereas CH intake significantly reduced intestinal P absorption. CH caused a significant reduction in BMD and stiffness of femurs as well as fourth lumbar vertebrae (L4). The bone loss in CH rats was accompanied with an increase in urinary Ca excretion and a decrease in serum Ca as well as a significant increment in serum PTH and 1,25(OH)2D3. These results indicates that dietary chitosan with low Ca intake possibly induces the loss of bone mass by enhacing urinary Ca excretion, rather than by inhibiting Ca absorption, and that vitamin C supplementation could prevent bone loss caused by chitosan through the increment of retained Ca followed by suppression of urinary Ca excretion.

      • 군장국가산단(장항지구) 호안 설계

        권오기,고장희,남세현,김성구,Kwon. O-Gi,Ko. Jang-Hee,Nam. Se-Hyun,Kim. Seong-Goo 한국방재학회 2007 한국방재학회 학술발표대회논문집 Vol.2007 No.1

        This project is the 1st. stage for the foreshore reclamation at Jang-Hang area and its scope is to construct a seawall as outer facilities, road adjacent to the seawall and drainage gate. for the safe protections of the facilities at the reclaimed land hereafter, we adopted the mild slope rubble mound type for the seawall structure which was excellent in interrupting the wave overtopping, as a result of numerical & hydraulic model test about alternative 4 sections. For the flooding prevention of the reclaimed land, we planned the drainage system that could make the flood water level lower than the reclaimed land level. Also, we planned the eco-friendly waterfront area with 8 nature themes through the whole seawall sections.

        부동산개발이익의 배분에 관한 탐색적 연구

        최혁재(Choi, Hyuk Jae),장희순(Jang, Hee Soon) 대한부동산학회 2021 大韓不動産學會誌 Vol.39 No.1

        이 연구는 부동산개발사업의 성공에 중점 둔 금융 수요자(GP)와 사업참여에 신중하고 보수성향을 가진 금융 제공자(LP)간의 이익 배분의 합리성을 탐색하는 것이다. 다시 말해서, 부동산 개발사업의 지분 투자자간, 위험의 분배와 그에 비례한 합리적이고 바람직한 개발이익의 배분 구조를 규명하는 것이다. 이 연구는 2가지 관점에서 개발이익의 배분 구조를 분석한다. 첫째, 투자비율에 비례한 이익 배분 구조를 분석하고. 둘째, 허들을 추가한 상태하에서 발생하는 이익배분 구조를 탐색한다. 투자자 간의 투자비율에 비례한 이익 배분은 위험 기피적인 유한책임 투자자의 입장에서는 받아들이기 어려운 구조다. 또한 허들이 많아질수록 무한책임 투자자의 업무성과 향상은 추가수익의 발생으로 유인기능을 한다. 따라서, 부동산개발사업은 상당한 리스크를 수반하므로 워터폴 구조에 의한 무한책임 투자자와 유한책임 투자자의 개발이익 배분의 합리적 결정 모델을 제시한다. This study focuses on the possibility of structuring the business between the GP, which expects the success of the development project, and the LP, who is careful to participate in the project and has a conservative tendency. In other words, it iinvestigates a profit sharing structure between equity investors in a real estate development project and the distribution of risks and the corresponding reasonable and desirable development gains. This research will analyze Choi Hyuk-jae and Jang Hee-soon s existing research in 2020 from two perspectives. First, explore the profit-sharing structure proportional to the investment ratio. Second, we add four hurdles to identify a various profit-sharing structure. Distribution proportional to the investment ratio between each investor is difficult to accept for risk-averse limited liability employees. In addition, the more hurdles are introduced, the more additional promote is generated considering the performance of the general partner, which functions as an incentive design function. Therefore, in a real estate development project where significant risks are inherent, the distribution of development profit between the general partner and the limited partner under the Waterfall structure is inevitable.

      • 초광대역 원형 슬롯 패치 안테나의 최적 설계

        장준원,최경,황희용 강원대학교 정보통신연구소 2007 정보통신논문지 Vol.11 No.-

        In this paper, an ultra wideband(UWB) circular slot antenna fed by tapered microstrip line is presented. The designed antenna is composed of a tapered feed line, a circular slot and a circular patch. Important physical parameters concerned with the wideband characteristic are investigated and optimized. The operational bandwidth of the antenna is from 3.5 GHz to 13.8 GHz. The simulated and the measured data show good agreement each other.

      • 超音波根管形成方法의 根管象牙質 削除能力

        張熙鮮,曺圭澄 慶北大學校 齒科大學 1987 慶北齒大論文集 Vol.4 No.1

        The quantitative dentin-removing ability of ultrasonic synergistic system was studied to compare with conventional techniques such as hand instrumentation and Giromatic preparation. Standardized seventy-two extracted, single-rooted human teeth were divided into six groups of equal numbers. The instrmentation with number 40 for each group was done for 1 minute, as follows; Group 1:root canals were instrumented by the hand, H-file, push-pull stroke. Group 2:root canals were instrumented by the automated Giromatic, H-file, a quarter-turn push-pull motion. Group 3:root acanals were instrumented by the ultrasonics, H-file,push-pull action. Group 4:root canals were instrumented by the hand, K-reamer, push-pull stroke. Group 5:root canals were instrumented by the automated Giromatic, K-reamer, a quarter-turn push-pull motion. Group 6:root canals were instrumented by the ultrasonics, K-reamer, push-pull action. The mean weight loss on each group was statistically compared with each other by use of Student's t-test. The results were as follows: Ultrasonic techniques were significantly superior to conventional techniques, especially using of H-file. There was no statistically significant difference in ability of the hand and Giromatic techniques to remove intracanal dentin. The qroups used H-file instrumentation were more efficient than those of K-reamer in general.
