        Double-J 요관부목 유치 환자에서 시간 경과에 따른 증상의 변화

        한창희,하유신,박덕진,김수환,이용석,강성학 대한비뇨의학회 2005 Investigative and Clinical Urology Vol.46 No.11

        Purpose: This study was designed to assess the prevalence of various urinary tract symptoms and the development of tolerance over time in patients with short term, indwelling, double-J(D-J) ureteral stents using a specially designed questionnaire and a 10cm linear visual analogue scale (VAS). Materials and Methods: Fifty-nine patients(median age 46.0 years, range 18-65; 32 men and 27 women) who underwent ureteroscopic surgery for ureteral obstruction caused by benign conditions(stone or stricture) completed the study. All patients received polyurethane D-J ureteral stents (5 or 6Fr, 24 or 26cm) which were removed 19-55 days postoperatively. Urinary symptoms and pain questionnaires were obtained from each patient at postoperative 24 hours, one week, and on the day before stent removal. Tolerance to the stent was also assessed. Results: All patients reported one or more urinary symptoms. Flank and suprapubic pain were reported more often on voiding or when walking than at rest. Although urgency was reported more frequently over time, the other urinary symptoms remained unchanged. There was no significant difference between the VAS scores for 24 hours, the first week and the day before removal, either overall or when stratified by gender or type of occupation. A factorial analysis of variance analyzing the VAS score for the first week as a function of gender and type of occupation showed no significant effect. Conclusions: Almost all patients with short-term placement of indwelling D-J ureteral stent had untoward symptoms. Although the prevalence of urgency was significantly increased over time, the general tolerance remained unchanged.

      • 1.8A-GeV Ar핵-원자핵건판핵 충돌에서의 파쇄현상 연구

        金東鎬,韓昌熙 國立 昌原大學校 産業技術硏究所 1988 産技硏論文集 Vol.2 No.-

        The interaction mean free path of the 1.8A-GeV Ar in nuclear emulsion was obtained as (9±2)cm by use of the along-the-track scanning method and the average angular distributions of the secondary projectile fragments, which are compared with respect to the Kaplon's formula.

      • 英國海上保險에 있어서의 現實全損

        韓昌熙 서경대학교 1990 論文集 Vol.18 No.-

        Institute Insurance Clauses of England is used over the world, and Korean Supreme Court recognized the effectiveness of the choice of law clauses in it. Therefore we must understand the law and practice of English insurance. I have given focus in English marime insurance in this theme. A total loss in insurance law is one on account of which the assured is entitled to recover from the underwriter the whole of amount of his subscription. Actual total loss was formerly called an absolute total loss. The meaning of the expression actual total loss is reasonably clear on the face of it. It is obvious that in the case of actual total loss there is no point in a notice of abandonment, whereas the notice of abandonment is a condition precedent to the right of recovery for a constructive total loss, because there is by definition nothing to abandon and accordingly an actual total loss entitles the assured to claim from the whole amount of his subscription without giving such notice.

        AI모델을 적용한 군 경계체계 지능화 방안

        한창희,구하림,박복기 한국인터넷정보학회 2023 인터넷정보학회논문지 Vol.24 No.4

        The ROK military faces a significant challenge in its vigilance mission due to demographic problems, particularly the current aging population and population cliff. This study demonstrates the crucial role of the 4th industrial revolution and its core artificial intelligence algorithm in maximizing work efficiency within the Command&Control room by mechanizing simple tasks. To achieve a fully developed military surveillance system, we have chosen multi-object tracking (MOT) technology as an essential artificial intelligence component, aligning with our goal of an intelligent and automated surveillance system. Additionally, we have prioritized data visualization and user interface to ensure system accessibility and efficiency. These complementary elements come together to form a cohesive software application. The CCTV video data for this study was collected from the CCTV cameras installed at the 1st and 2nd main gates of the 00 unit, with the cooperation by Command&Control room. Experimental results indicate that an intelligent and automated surveillance system enables the delivery of more information to the operators in the room. However, it is important to acknowledge the limitations of the developed software system in this study. By highlighting these limitations, we can present the future direction for the development of military surveillance systems.

      • テナガエビの生殖周期に關する生理學的硏究

        韓昌希 朝鮮奬學會 1988 學術論文集 Vol.17 No.-

        甲殻類は魚類とならび水産上重要な位置を占め るにもかかわらず,生殖周期やその成立機構につ いて詳細に調べた報告は殆どなし、。生殖周期や生 殖機構を明らかにすることは成熟・産卵の人工制 御を目指す上で重要で、ある。そこで,テナ力、エビ (Macrobrachium niρρonense)を実験材料に用 い,まず生殖年周期を明らかにした上で,その成 立機構を明らかにした。さらに卵黄蛋自の精製を 行い,酵素免疫測定法(ELISA)による卵黄蛋白 前駆物質(ビテロジェニン)定量システムを確立 し,産卵周期における血中ビテロジェニンの経時 的変動を調べるとともに免疫組織化学的手法によ りその産生部位の同定を試みた。

      • 동자개, Pseudobagrus fulvidraco (Richardson)의 생식년주기

        한창희,임상구 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1

        To clarify the annual reproductive cycle of the banded catfish, Pseudobagrus fulvidraco(Richardson), the seasonal changes in histological aspect of gonad and liver were examined. The adult fish was captured from the upper stream of Young-San river, Chunnam in each month from May 1992 to June 1993. Based on the annual changes in GSI (gonadosomatic index), HSI (hepatosomatic index), CF (condition factor) and histological aspects of the gonads, the annual reproductive cycle were classified into 5 periods as follows: 1) Growing phase (from April to early May): The value of GSI increased and the size of oocytes in perinucleolus stage in oocytes increased gradually. Spermatogonia were developed actively from the epithelial tissues of seminiferous tubules. 2) Maturing phase (from May to early June): GSI levels increased rapidly in both sex. Oocytes at various developmental stages were observed. Appearance of active spermatogenesis were observed. 3) Mature and spawning phase (from June to August): High values of GSI remained static and oocytes accumulated significant quantitis of yolk globules. 4) Degenerating phase (from September to November): GSI levels decreased and ovaries were filled mostly with oocytes at the perinucleolus stage. Hepatic cells accumulated significant amounts of lipid droplets. 5) Resting period (from December to March) : Low values of GSI were kept and the size of oocytes at the perinucleolus stage did not increase. Spermatogenesis was not observed.
