Construction companies economic to lighten the restrictions on safety education and training due to the domestic recession as long as the global downturn. With this, the Korean government restrictions, but the incidents are being sharply increased nowadays. The construction industry hazardous than any others, so, they insist to reinforce the training for incidents prevention, to be disregarded at the subcontractors of the bigger construction companies problems. According to these matters, this study hereby surveyed regarding their suggestions for the improvements of the training concepts through questionnaires below.

Construction incidents, mechanisms and causes in Geotechnical Engineering have been closely reviewed for the safety assurance during design and construction stages. The safety assurance is clearly related to the observational method in which design is reviewed during construction and contingency actions are undertaken successfully to minimise any potential failures. The observational method has been extensively applied for the construction of subways underground structures, dams and many important Civil Engineering projects in the past 20 years. But the number of serious construction incidents are growing for the past several decades. Therefore present development of observational method and improvement techniques are introduced with some case histories.

It is necessary to analyze the railway accidents and incidents for the purpose of understanding present safety state and enhancing its system. Korea National Railroad has its accident/incident reporting codes, but it is relatively not sufficient for detail classification and investigation of accident and incident compared with foreign countries. This paper suggests how to classify the railway accident/incident, and describes the analysis result for domestic recent railway accidents and incidents according to the new suggested classifying system.

Human factor represents a very challenging issue to organizations. Human factor is responsible for many cybersecurity incidents by noncompliance with the organization security policies. In this paper we conduct a comprehensive review of the literature to identify strategies to address human factor. Security awareness, training and education program is the main strategy to address human factor. Scholars have consistently argued that importance of security awareness to prevent incidents from human behavior.

Background: Implanted venous access devices or permanent central venous access systems (PCVASs) are routinely used in oncologic patients. Complications can occur during the implantation or use of such devices. We describe such complications of the PCVAS and their management. Methods: Our retrospective study included 1,460 cases in which PCVAS was implanted in the 11 years between January 2002 and January 2013, including 810 women and 650 men with an average age of 45.2 years. We used polyurethane or silicone catheters. The site of insertion and the surgical or percutaneous procedure were selected on the basis of clinical data and disease information. The subclavian and cephalic veins were our most common sites of insertion. Results: About 1,100 cases (75%) underwent surgery by training surgeons and 360 patients by expert surgeons. Perioperative incidents occurred in 33% and 12% of these patients, respectively. Incidents (28%) included technical difficulties (n=64), a subcutaneous hematoma (n=37), pneumothoraces (n=15), and an intrapleural catheter (n=1). Complications in the short and medium term were present in 14.2% of the cases. Distortion and rupture of the catheter (n=5) were noted in the costoclavicular area (pinch-off syndrome). There were 5 cases of catheter migration into the jugular vein (n=1), superior vena cava (n=1), and heart cavities (n=3). No patient died of PCVAS insertion or complication. Conclusion: PCVAS complications should be diagnosed early and treated with probable removal of this material for preventing any life-threatening outcome associated with complicated PVCAS.

교통 혼잡으로 인한 사회적 비용이 증가하면서 도로 속도를 예측하기 위한 다양한 연구들이 진행되고 있다. 도로 속도 예측의 정확도를 향상시키기 위해서는 교통 돌발 상황을 고려할 필요가 있다. 본 논문에서는 교통 돌발 상황을 고려한 도로 속도 예측 기법을 제안한다. 제안하는 기법은 연결된 도로들이 미치는 영향을 반영하기 위해서 예측 도로의 속도 데이터 뿐만 아니라 연결된 도로들의 속도 데이터도 이용한다. 또한, 돌발 상황으로 인한 혼잡을 예측하기 위해 속도의 변화량을 분석한다. 연결된 도로와 타겟 도로의 속도 데이터를 LSTM의 입력 데이터로 이용하여 1차적으로 도로 속도를 예측한다. 교통 돌발 상황으로 도로의 규칙적인 흐름이 깨지며 발생하는 예측 오차를 줄이기 위해 이벤트 가중치를 적용하여 최종적으로 도로 속도를 예측한다. 다양한 성능 평가를 통해 제안된 방법의 우수성을 입증한다.
