현 화재 감식 및 조사에서는 일반적으로 화재 조사관의 경험이나 지식으로 판단하는 사례가 있다. 그러나 PL법 및 실화책임법에 따라 국내에서도 과학적 화재조사방법론이 필요시되고 있으며 이에 따라 본 연구에서는 과학적 화재감식 및 화재조사방법론의 일환으로 FDS를 이용한 화재조사매뉴얼의 필요성에 대해서 조사하였다. 그러나 현재 FDS를 화재조사 및 감식에 무분별하게 이용하기에는 어려움이 있으며 이를 활용하기 위한 기초적 화재데이터의 수집이 필요하다고 판단된다.

Alopecia is usually presented as patchy, no scarring hair loss. It seems to be a hormonal imbalance or an immune mediated disease, whereas genetic predisposition, environmental and psychological factors may be involved in its etiology. Many treatments of alopecia disease have been widely applied, but their side effects are also well known. The purpose of this study is to demonstrate efficacy and safety of a food supplement containing medicinal plant extracts, amino acid and vitamin complex on the prevention of hair loss in human. A total of 20 subjects aged between 29-50 years with subjective hair loss complaint were recruited for this study. Each subject took 1 g/day supplement for 3 months. 5-Scale self-assessment test, hair loss count and measurement of hair thickness were conducted to evaluate the effect of supplement on the improvement of hair loss. Subjective hair loss was decreased and hair damage and thickness were improved in self-assessment test. After 3 months of supplementation, hair loss counts were decreased (P<0.05) while hair thickness was increased(P<0.001) significantly. There was no side effect observed during the study. These results suggest that the supplement consist of medicinal plant extracts, amino acid and vitamin complex might be useful for the improvement of hair loss with no significant side effects.

This study aims to determine the cause of the load resistance loss in storage racks that can be attributed to external forces such as earthquakes and to improve safety by developing reinforcement systems that can prevent load resistance loss. To this end, a static cyclic loading test was performed on pallet racks commonly used in logistics warehouses. The test results indicated that a pallet rack exposed to an external force loses more than 50% of its load resistance owing to the damage caused to column-beam joints. Three reinforcement systems were developed for preventing load resistance loss in storage racks exposed to an external force and for performing differentiated target functions: column reinforcement device, seismic damper, and viscoelastic damper. Shake table testing was performed to evaluate the earthquake response and verify the performance of these reinforcement systems. The results confirmed that, the maximum displacement, which causes the loss of load resistance and the permanent deformation of racks under external force, is reduced using the developed reinforcement devices. Thus, the appropriate selection of the developed reinforcement devices by users can help secure the safety of the storage racks.

Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.

Background: Caveolin-1 (CAV-1), encoding the structural component of cellular caveolae, is a suggested tumor suppressor gene involved in cell signalling. Aberrant promoter methylation of CAV-1 is associated with inactivation of expression. We previously observed CAV-1 mutations in breast cancers and therefore devised this study to examine the hypermethylation status of the promoter region of CAV-1 with reference to breast cancer progression and development. Methods: Hypermethylation status of CAV-1 was analyzed by methylation specific PCR. Loss of expression of the CAV-1 gene was further evaluated by semi-quantitative rt-PCR. Results: 28/130 (21.5%) breast cancer cases showed promoter hypermethylation with reduced CAV-1 expression levels when compared with adjacent normal breast tissue. CAV-1 gene hypermethylation was significantly related to menopausal status, histopathological grade and age. Conclusion: The rationale of our study is that CAV-1 gene is transcriptionally repressed in breast cancer cells due to hypermethylation. Our results reveal that promoter hypermethylation and loss of expression of the CAV-1 gene is an important alternative mechanism for inactivation of CAV-1 leading to complete gene silencing.

Video-assisted thoracic surgery (VATS) has been recommended as more optimal surgical technique than traditional thoracotomy for lobectomy in lung cancer, but it is not well defined. Here, we compared VATS and traditional thoracotomy based on clinical data. From November 2008 to November 2010, 180 patients underwent lobectomy for non-small-cell lung cancer (NSCL) identified by computerized tomography. Of them, 83 cases were performed with VATS and 97 by thoracotomy. Clinical parameters, consisting of blood loss, operating time, number of lymph node dissection, days of pleural cavity drainage, and length of stay were recorded and evaluated with t test. No significant difference was observed between the VATS and thoracotomy groups in the average intraoperative blood loss, number of lymph node dissections, and days of pleural cavity drainage. While the average operating time in the VATS group was significantly longer than that in thoracotomy group, recurrence was only present in one case, as opposed to 7 cases in the thoracotomy group In conclusion, similar therapeutic effects were demonstrated in VATS and thoracotomy for NSCL. However, VATS lobectomy was associated with fewer complications, recurrence and shorter length of stay.

본 논문에서는 SFC(Service Function Chaining) 기반 DLP(Data Loss Prevention) 솔루션을 위한 부하분산 시스템을 제안한다. SFC을 기반한 DLP 솔루션은 사용자의 데이터를 분산 처리하지 않으며, 각 DLP 서버는 할당 받은 사용자 단말에서 발생되는 모든 트래픽을 관리한다. 하지만 사용자별 트래픽 사용량이 다르기 때문에 DLP 서버의 리소스 사용량과 유휴량을 고려하지 않는 기존의 순차방식, 최소접속방식과 같은 부하분산 알고리즘을 사용 할 경우 트래픽이 균등하게 분배되지 못 하여, DLP 서버의 과부하 및 시스템 장애를 발생시킨다. 따라서 본 논문에서는 LBM(Load Balance Management) 서버를 통해 DLP 서버의 리소스 사용량을 기반으로 부하분산을 수행하는 SFC 기반 DLP 솔루션을 위한 부하분산 시스템의 아키텍처를 제안한다.
