The twenty-three cases of unstable Colles fracture were treated from Jan. 1994 to May 1998 at the department of orthopaedic surgery of Seoul Red Cross Hospital. Among them, the sixteen cases were treated with closed reduction with percutaneous pinning, others were treated with external fixator(Ace colles quadrilateral devices, USA). A retrospective study was made and evaluated using the Modification of Gartland and Werley's scoring system. The result of this study were as follow: 1. The ratio of male to female was 9 cases(39%) to 14 cases(61%). 2. The causes were falling down from a height 12 cases(50%), slip down 8 cases(35%) and traffic accident 3 cases(13%). 3. The reduction loss did not occur with the patients treated external fixation using Ace colles qredrilateral device, however three cases of the reduction loss have occurred with the patients using percuteneous pinning. 4. According to the Modification of Gartland and Werley's scoring system, the results of external fixation were excellent 4 cases(58%), good 1 case(14%), fair 1 case(14%) and poor 1 case(14%). and for percuteneous pinning, excellent 6 cases(38%), good 4 cases(25%), fair 2 cases(12%) and poor 4 cases(25%). 5. The complications of cases using external fixation were pin site infection 1 case and wrist stiffness 1 case, but for percutaneous pinning, reduction loss 3 cases. pin site infection 2 cases, wrist stiffness 2 cases, and decreased external rotation of forearm 3 cases.

한국 드론산업 발전을 위한 정책적 제안

황태성,강경수 국제차세대융합기술학회 2022 차세대융합기술학회논문지 Vol.6 No.10

Today, the drone industry in Korea has emerged as the core of the era as a characteristic of convergence of representative technologies in the 4th industrial era, and its use and scope are gradually expanding, and research and development are being actively carried out in various fields. However, the preparation is somewhat insufficient compared to the social action of new technology, that is, the diversity of drone use and the frequency required in many fields. For the development of the Korean drone industry, the following government policy measures should be proposed. First, drone-related education should be improved and drone academic organizations should be activated. Second, it is judged that laws and systems related to drones should be improved. Third, a review of anti-drone-related policy measures is urgently required. Fourth, policy measures should be prepared to revitalize the drone industry. 오늘날 한국의 드론산업은 4차산업 시대의 대표 기술이 융합된 분야라는 특성으로 시대의 핵심으로 부상 하면서, 그 용도와 범위가 점점 확대되고 있으며, 다양한 분야에서 적극적으로 활용하기 위한 연구・개발이 활발히 이루어지고 있다. 하지만 신기술에 대한 사회적 작용, 즉 드론활용의 다양성과 계속적으로 많은 분야에서 요구 되 어지는 빈도에 비하여 준비가 다소 부족하다. 따라서 한국드론산업의 발전을 위해서는 다음과 같은 정부의 드론산 업의 정책적 방안이 제시되어야 한다. 첫째, 드론 관련 교육의 개선과 드론 학술단체의 활성화가 이루어져야 할 것이다. 둘째. 드론과 관련된 법과 제도가 개선되어야 할 것으로 판단된다. 셋째, 안티드론 관련 정책방안의 검토 가 절실히 요구된다. 넷째, 드론산업 활성화를 위한 정책적 대책이 마련되어야 한다.

A 10-month-old intact male Scottish Fold was presented with cardiomegaly. The cat showed exerciseintolerance after birth. Radiographs showed cardiomegaly with bulging of the main pulmonary artery and dilation ofpulmonary arteries. Echocardiogram revealed abnormally arisen aortic root toward right ventricle with left-to-rightshunted perimembraneous ventricular septal defect located underneath the aortic root. Based on imaging studies, thecat was diagnosed as subaortic type of double outlet right ventricle (DORV) without concurrent abnormalities.

Freight Demand Forecasting Considering Economic Growth Factors

황태성 인하대학교 정석물류통상연구원 2017 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.15 No.2

This work proposes a methodology to project future freight demand for all commodity types that begin and end in each geographical region and the amount of freight that moves between all origin and destination pairs. Following the traditional four-step demand forecasting framework, the procedure corresponds to trip generation and trip distribution analysis for interregional freight demand. Using future economic growth factors from macroeconomic and input-output models, the amounts of freight production and attraction in each analysis zone are forecasted and taken as given. Subsequently, an iterative matrix balancing method is applied to determine the estimated freight shipment demand for all origin and destination zone pairs. The proposed algorithm is applied to generate predicted future freight demand within the United States from 2010-2050 in five-year increments based on the national freight demand data from 2007. Four different scenarios are proposed that consider variations in both global economic growth and environmental regulation. This study will assist transportation planners and decision makers in public and private sectors to assess how future freight delivery demand on the national scale considering various future global economic growth and environmental policy scenarios will affect various issues such as air quality and human health problems.

Ultrasonographic and Computed Tomographic Appearance of Spontaneous Cutaneous Fistula Resulted from Retained Surgical Gauze in a Dog

황태성,허찬,이희천 한국임상수의학회 2019 한국임상수의학회지 Vol.36 No.4

A 6-year-old, spayed female Maltese was presented with the condition of a chronic recurrent abscess formation in the left flank region. Despite the antibiotics and drainage therapy given to the dog, the lesion formed a continued serosanguineous to the point that a purulent discharge was evident. In the meantime, an abdominal ultrasound revealed the presence of a well-defined mass with a hypoechoic outer margin, and a hyperechoic inner rim in the cranial of the kidney. A fistula was noted as being present with a connection between the subcutaneous lesion of the left flank and the abdominal mass. It is emphasized that CT scans revealed the existence of a soft tissue dense mass with low attenuation area, as seen in some internal areas and also a peripheral contrast enhancement was noted within a nonenhancing central region. There was additional nonenhancing fluid found dorsal to the inflammatory tract passing under the epaxial muscles and at the peritoneum. Likewise, the tract exited the skin surface in the left flank. A tentative diagnosis of an abdominal abscess with spontaneous cutaneous fistula was made based on the ultrasonographic and CT appearances. A foreign body such as surgical gauze should always be considered a potential cause of draining tract in small animals, as was considered to be the problem in this case.

국내 운항선박 내항성능해석을 위한 우리나라 해역의 파랑특성 연구

The hull structural rule is applied to domestic voyage vessels and is almost the same as the class hull rule. The class hull rule was developed based on the North Atlantic and is also applied to small vessels with length not greater than 90m. It is more reasonable to apply wave loads developed based on South Korea to domestic voyage vessels. However, there is no information to calculate a design wave for a domestically operated ship because an analysis of the design wave conditions around South Korea has not been done yet. In this study, a design wave condition for application to domestic navigation ships was selected using a short and long-term prediction method. The wave heights corresponding to 1-year and 20-year return periods were estimated to be about 17.98m(amplitude 8.99m) and 20.68m(amplitude 10.34m). 국내 항해에 종사하는 선박의 선체구조규칙은 대부분 북대서양을 기준으로 개발된 선급 규정을 따르도록 되어있으며, 더욱이 90m 이하인 소형선박에도 이러한 가혹한 규정이 적용되고 있어 이에 대한 개정이 요구된다. 따라서 우리나라 주변만을 항행하는 선박에 대해서는 우리나라 해역을 기준으로 개발된 파랑하중을 적용할 필요가 있다. 그러나 아직까지 우리나라 해역에 대한 설계 파랑조건에 대한 분석이 이뤄지지 않아, 설계파를 산정하는데 필요한 정보가 없는 실정이다. 본 연구에서는 국내 항행선박에 적용하기 위한 설계파랑 조건을 선정하고자 하였다. 이를 위해서 파도 산포도를 바탕으로 단장기 예측을 통해 설계파를 산정하였다. 그 결과 1년과 20년에 1회 발현하는 파의 파고는 17.98 m(진폭 8.99 m), 20.68 m(진폭 10.34 m)인 것으로 산정되었다.

Acquired Portosystemic Shunts Secondary to Hepatic Microvascular Dysplasia in a Young Dog

황태성,안소연,김아름,한창희,허찬,이희천 한국임상수의학회 2020 한국임상수의학회지 Vol.37 No.2

A one year old spayed female Bichon Frise dog presented with gait abnormalities and seizure. Serum biochemical results showed elevated levels of alkaline phosphatase, alanine aminotransferase, and ammonia. Serum bile acid level was also increased to be over 30 mol/L on preprandial. Urinalysis identified the presence of ammonium urate crystal. Abdominal ultrasonography and CT revealed aberrant, tortuous, and multiple small vessels connected to the caudal vena cava between left kidney and caudal vena cava. Macroscopic specific findings associated with extrahepatic congenital portosystemic shunts (PSS) or other liver diseases were not identified. Liver biopsy was performed. Histopathologic evaluation revealed hepatic lobular hypoplasia with portal arterial duplication and vascular shunts. Based on these finding, this case was diagnosed as multiple acquired PSS secondary to hepatic microvascular dysplasia (HMD) and hepatic encephalopathy. A liver biopsy is recommended to differentiate HMD from other liver diseases and to confirm HMD when a young dog has multiple acquired PSS.
