현재 우리나라 신호교차로는 긴급차량에 대한 우선신호(Preemption) 제어전략을 적용하지 않고, 긴급차량의 교차로 진입 및 통과여부와 관계없이 일반적인 신호로 운영되고 있다. 본 연구에서는 국내외 긴급차량 Preemption 제어 전략을 검토하고. 이를 국내 교통상황을 대상으로 시뮬레이션을 통해 평가하여 교통상황에 따른 효과의 변동성을 분석하였다. 그리고 실제 현장자료를 기반으로 평가하여 국내 적용성 평가를 실시하였다. 분석결과 긴급차량 preemption 제어가 긴급차량의 운영에 긍정적인 영향을 주나 v/c가 증가 할 수록 이와 같은 효과는 감소하는 것으로 나타났다. 그리고 일반차량의 경우는 preemption 제어로 인하여 지체가 증가하고 통행속도가 감소하였으나 네트워크 전체적으로는 큰 차이가 없는 것으로 분석되었다. 그러므로 교통상황에 따라 개선효과의 차이는 존재하지만, preemption 제어 알고리즘을 국내에 도입한다면 사회적으로 긍정적인 효과가 있을 것으로 기대된다.

평형수처리장치는 고가이며, 현존선에는 설치시 기술적으로 고려할 사항이 많고 설치시간 또한 많이 걸린다. 더불어, 평형수관리협약이 발효되지 않은 상황에서 총회 결의로 탑재시기를 조정하였으며, 미국의 캘리포니아주 및 뉴욕주에서는 IMO D-2 규칙보다 엄격한 평형수 배출 기준을 적용하고자 하고 있으며, 그 시행시기도 협약보다 조기에 시행하고자 하고 있다. 이러한 상황에서 평형수처리장치 제조자와 선주의 이해가 상이한 부분의 고려가 필요하다. 이 연구에서는 선박 탑재시의 고려사항, 미국의 강화된 기준 및 협약의 시행시기 유예 사항을 검토하여, 앞으로 다가올 선박평형수관리협약의 발효와 미국의 강화된 기준 시행에 대비한 각 이해 당사자들의 전략을 제시하고자 한다.

이 연구는 게임중독 치료를 위한 새로운 접근으로 디지털스토리텔링을 활용한 교육 프로그램의 개발 전략을 제안하였다. 우선 디지털스토리텔링 수업을 위한 교육내용을 5가지 멀티미디어 요소로 선정하고 게임중독 치료를 위한 교육전략과 절차를 마련하였다. 5명의 게임중독 위험군 학생을 선발하여 개발된 프로그램을 적용하였고 게임중독 검사, 게임이용시간 검사, 회기별 관찰과 면담, 제안된 프로그램의 효과성 검사를 실시하였다. 검사결과, 제안된 프로그램이 게임중독 경향성의 감소에 긍정적인 효과를 가져왔고, 디지털 스토리텔링 전략의 효과 분석에서 디지털스토리텔링 과정을 통해 느끼는 몰입감, 참여와 도전, 사회적 상호작용, 성취도가 높은 것으로 나타났다. 제안된 디지털스토리텔링 프로그램은 게임중독 치료에 긍정적인 역할을 할 수 있을 것으로 기대한다.

Objective: Endometrial fibrosis, the primary pathological feature of intrauterine adhesion, may lead to disruption of endometrial tissue structure, menstrual abnormalities, infertility, and recurrent pregnancy loss. At present, no ideal therapeutic strategy exists for this fibrotic disease. Eupatilin, a major pharmacologically active flavone from Artemisia, has been previously reported to act as a potent inducer of dedifferentiation of fibrotic tissue in the liver and lung. However, the effects of eupatilin on endometrial fibrosis have not yet been investigated. In this study, we present the first report on the impact of eupatilin treatment on transforming growth factor beta (TGF-β)-induced endometrial fibrosis. Methods: The efficacy of eupatilin on TGF-β-induced endometrial fibrosis was assessed by examining changes in morphology and the expression levels of fibrosis markers using immunofluorescence staining and quantitative real-time reverse-transcription polymerase chain reaction. Results: Eupatilin treatment significantly reduced the fibrotic activity of TGF-β-induced endometrial fibrosis in Ishikawa cells, which displayed more circular shapes and formed more colonies. Additionally, the effects of eupatilin on fibrotic markers including alpha-smooth muscle actin, hypoxia-inducible factor 1 alpha, collagen type I alpha 1 chain, and matrix metalloproteinase-2, were evaluated in TGF-β-induced endometrial fibrosis. The expression of these markers was highly upregulated by TGF-β pretreatment and recovered to the levels of control cells in response to eupatilin treatment. Conclusion: Our findings suggest that suppression of TGF-β-induced signaling by eupatilin might be an effective therapeutic strategy for the treatment of endometrial fibrosis.

Objective : To study the Oriental Medicine-based strategies or therapeutics for chronic HBV infection. Methods : A chronic HBV carrier was treated with only oriental therapies. Then, serum biochemical parameters were serially chased, and change of HBV-DNA level was evaluated. Result : The biochemical indicators (AST, ALT, gamma-GTP, bilirubin) fluctuated during the treatment period. After one episode of drastic elevation of serum aminotransferase, HBV-DNA disappeared from the blood along with normalization of biochemical parameters within two years of beginning treatment. Conclusion : Oriental Medicine-based therapeutics could be an alternative strategy against chronic infection of HBV.

Since establishment some 25 year ago, AMITA Corporation has continued its attempts in meeting customer needs, in reducing costs for waste treatment. The solutions we have proposed in the past made use of our networks entailing Japan as well as the East Asian region. However, as enterprises have changed their perspective approaching environmental issues recently, as needs diversify, AMITA too has been changing its strategy to incorporate the use of Information Technology to provide consulting services. AMITA has set its goals in promoting modernization of the waste treatment industry, and optimizing the recycling market to reduce environmental impacts.

Orbital fractures have a significant portion in facial bone trauma. The important thing in treatment of orbital fractures is variable depending on the patient. Reconstruction of orbital wall demands an understanding of the anatomy and function of the orbit, including the orbital tissues, and the approacheds, materials, and methods available.

Development of antiviral resistance to lamivudine is the most important factor for the treatment failure. It is necessary to establish proper guidelines to overcome drug resistance for children with chronic hepatitis B. Primary treatment with lamivudine should be considered if patients are in immune-clearance phase and have persistently elevated ALT levels more than twice the upper limit of normal value. Before initiating the therapy, careful consideration of the patient's status is required to exclude abnormal liver function tests due to other causes. The treatment option should be carefully decided to suppress the viral replication effectively. To obtain good compliance, clinicians should educate patients and their parents. Appropriate monitoring for virologic breakthrough and genotypic resistance is important in deciding to change the treatment plan. Sequential monotherapy should be avoided and a combination of drugs in other categories is recommended. New antiviral agents, such as entecavir and tenofovir, which have high potency and high genetic barrier, are soon expected to be available for use with children.

Conversion disorder is defined as a specific and enduring sensorimotor dysfunction that contradicts known neurological or musculoskeletal pathology or physical findings. The patient with conversion symptoms unconsciously adopts these symptoms to convert their psychological stress to a physical phenomenon. Conversion disorder often involves the mimicry of organic symptoms similar to those experienced by a relative or an acquaintance. Because conversion symptoms are produced by psychological stress, specific treatment strategy and reinforcement program are needed for treatment. Treatment comprises avoiding unnecessary medical tests and removing symptoms by using graded exercises given by physical therapists. Clinical therapists must maintain a continuous and detailed follow-up to completely recover from conversion symptoms. The goal of treatment is to emphasize health rather than disease, to resolve physical symptoms, and to prevent recurrence. This study looks into the case reports of 4 patients diagnosed with conversion disorder.

Obstructive sleep apnea syndrome (OSAS) can lead to severe complications if left untreated, and therefore should be adequately diagnosed and treated, especially in airline workers. The aviation medical examiner (AME) should induce the patient to cooperate for the diagnosis and treatment of OSAS, by notifying the subject that it does not cause disqualification of the air service and that it is a disease that can be sufficiently controlled and treated by various treatment options. AME should also warn about medical complications and the possibility of serious air accident risks when untreated, and encourage the subject to receive appropriate diagnosis and steady treatment such as continuous positive airway pressure and/or surgical treatment.
