The object of this research is to develop a simulation system for earthmoving operations in consideration of the impact of congestion in-between equipment and existing traffic flow around the site. The congestion in-between equipment and traffic flow affect work productivity. The conventional discrete event simulation, however, has limitations in simulating the flow of construction equipment. To consider the impact of congestion in-between equipment and existing traffic flow, in this paper, a multi-agent based simulation model that can realize characteristics of truck behavior more accurately to consider the impact of congestion was proposed. In this simulation model, multiple agents can identify environmental changes and adapt themselves to the new environment. This modeling approach is a better choice for this problem since it describes behavioral characteristics of each agent by sensing changes in dynamic surroundings. This study suggests a detailed system design of the multi-agent based simulation system.

The pre-assembly takes a large portion of the fabrication cost of steel bridges. In order to save the fabrication cost through the improvement of the conventional pre-assembling process, this research investigates a numerical pre-assembly simulation as an alternative to current pre-assembling process. The 3D laser scanning was utilized in site and measuring data for steel box were analyzed. The productivity of pre-assembly simulation system is compared with the conventional pre-assembling system. This paper identifies feasibility on the alternative pre-assembling process and then proposes the scheme of the pre-assembly simulation system development satisfying the current pre-assembly inspection of standards.

노후 선박의 증가로 선체 검사의 필요성이 높아지고 있다. 하지만 선체 벽면의 균열을 찾고 보수하는 작업은 위험성이 높고 효율성이 낮다. 이에 본 논문에서는 선체의 벽면에 진공 흡착하여 장애물에 부딪히지 않고 선체 벽면을 이동하면서 균열을 탐지하는 로봇을 개발하였다. 선체 균열탐지 로봇은 선체뿐만 아니라 사람이 직접 균열을 찾기 힘들거나 위험한 곳에 유용할 것이며 균열로 인한 선박 사고 발생을 줄여줄 것으로 기대된다.

Angiosarcoma is a very rare soft tissue sarcoma that originates from endothelial cells and typically has a poor prognosis. It is most commonly found in elderly white men and can occur anywhere in the body, particularly in the head, neck, and scalp. Patients who have undergone previous radiation treatment or who have chronic lymphedema also face an elevated risk of this condition. Various genetic changes are suspected to contribute to the development of angiosarcoma, and these changes have been identified as potential targets for treatment. For localized disease, wide surgical resection is often the prudent course of action. A multidisciplinary approach, which may include surgery, radiotherapy, systemic chemotherapy, or immunotherapy, is typically the most effective way to achieve favorable outcomes. In this review, we discuss the general understanding of angiosarcoma and its management, with a particular focus on the current evolving treatments for the disease.

There are few reports of the pleuropulmonary involvement of a non-typhi Salmonella infection in immunocompromised patients with AIDS, malignancy, collagen vascular diseases, extended use of corticosteroids, sickle cell disease, or diabetes. We report a case of a non-immunocompromised patient who presented with concomitant empyema and mediastinitis due to Salmonella without a comorbid disease. A 26-year-old male patient, with a history of pneumonia 5 years earlier and having lived abroad for several years, presented chronic cough and febrile sensation. Pneumonia, empyema and mediastinitis were noted in a chest CT scan and Salmonella enteritidis and ${\beta}-hemolytic$ streptococcus were identified from a culture of the pleural fluid. Initially, he was treated with cefepime, metronidazole and clarithromycin. He was cured clinically and radiographically after an 8 week treatment with antibiotics. In conclusion, this report suggests that S. enteritidis can cause empyema and mediastinitis, albeit rarely.

Recently, a large number of people are growing interested in Korean cuisine and progress Korean culture. This study inverstigated several kinds of Korean traditional alcoholic drinks and brewing methods, including ingredients in ancient culinary manuscripts "Soowoonjabbang", "Eumsikdimibang", "Onjubub", "Jusiksiui", "Uumjeabang" and "Eumsikbangmunnira" of Korean head family. Korean traditional alcoholic drinks were sorted into two groups based on characteristic (danyang ju, yiyang ju, samyang ju, sayang ju, yakyoung ju, gahyang ju, honyang juand soju) and five categories based on preconditioning methods of Korean traditional alcoholic drinks (iporrige, baeksul ki, gumung tteok, godubap, bumbuck). The most announced ancient Korean culinary manuscript is "Onjubub" (57 varieties of Korean traditional alcoholic drinks), the second largest book is "Eumsikdimibang" (49 varieties of Korean traditional alcoholic drinks), and the third highest book is "Soowoonjabbang" (40 varieties of Korean traditional alcoholic drinks). The "Uumjeabang" and "Eumsikbangmunnira" announced 21 and 15 varieties of Korean traditional alcoholic drinks in six books of ancient Korean culinary manuscripts, respectively.

최근 질병 분석 및 신약을 개발하기 위한 단백질에 대한 연구는 생명 공학의 큰 테마 중 하나이다. 질병 및 단백질 데이터를 분석하기 위한 연구는 대용량의 데이터 처리를 요구하기 때문에 과거 실험을 통해 접근하던 방식에서 벗어나 최근 IT 기술의 결합을 통해 다양한 실험 데이터를 공유하고, 연계함으로써 연구를 가속화하고 있다. 하지만 생명 공학 연구자에게 있어서 IT 지식을 기반을 둔 단백질 분석 도구를 다루는데 많은 어려움이 있다. 이러한 문제를 해결하고자, IT 연구자와 생명 공학 연구자의 협업을 통한 데이터 분석 도구를 개발이 폭넓게 시도되고 있지만, 연구자 간의 협업을 도울 수 있는 통합 인프라는 전무한 실정이다. 본 논문에서는 IT 연구자와 생명 공학 연구자의 협업을 위한 인프라로서 컴포넌트 기반의 질병 및 단백질 데이터 분석 시스템을 설계하고 구현한다.

This study was aimed to evaluate the effects of quercetin and desferrioxamine on the development of the reflux esophagitis induced surgically, on gastric secretion and on lipid peroxidation which is a marker of oxidative stress. Omeprazole was used as a positive control drug. Omeprazole significantly and dose-dependently prevented the development of reflux esophagitis, but quercetin or desferrioxamine prevented only at high dose. Omeprazole significantly and dose-dependently inhibited the gastric acid secretion (gastric volume, pH and acid output), but quercetin or desferrioxamine did not inhibit. Malonyldialdehyde content, the end product of lipid peroxidation, increased significantly after the induction of reflux esophagitis. Omeprazole prevented lipid peroxidation. Quercetin and desferrioxamine inhibited the lipid peroxidation independent of their actions on gastric secretion. This result indicates that omeprazole confirmed preventing effect of rat reflux esophagitis, but quercetin and desferrioxamine inhibited esophagitis by reduction of lipid peroxidation irrespective of gastric acid secretion.

De-icing salts applied to roads during winter enable safe driving conditions. However, these salts are eventually displaced to roadside areas at which they can negatively impact soil, vegetation, and water resources. This purpose of this study is to determine the relationship between foliar damage ratio (NY = 0-25%, SY = 26-50%, CY = 51-75%) on roadside trees (Ginko biloba) and seasonal impact of de-icing salts on soil and vegetation. Thirty roadside trees were selected at 8 m intervals between the Konkuk and Judeok intersections in Chung-ju city. The results reveal that seasonal soil acidity is relatively alkaline for foliar damage ratio of Ginko biloba was CY compared to NY. Also, electronic conductivity of each seasonal sampling was recorded as high in winter and spring, whereas the opposite trend is observed in summer. Various plants species were identified in abundance under roadside trees within NY roadside sections. These same species were observed in reduced numbers within CY sections. Strong negative correlations were identified between foliar damage ratio on roadside trees and vegetation. This relationship may be a method to use in predicting the accumulation of de-icing salt and visible injuries on roadside trees.
