  • Current [Guideline for Installation and Management of Sidewalks and Safety Facilities on Roads] suggests that the types of curbs should be Barrier curb ($85^{\circ}$). Although Barrier curbs ($90^{\circ}$) were not specified in the guideline. The curbs installed on the roads currently are Barrier curbs ($90^{\circ}$) which are not specified in the installation standard. Therefore, it is critical to prepare for the installation standard of curbs by researching types of curbs and driving safety. This research have assessed the driving safety throughout Full Scale Crash Test according to type of curbs (Barrier curbs ($85^{\circ}$) and Barrier curbs ($90^{\circ}$)). Barrier curbs ($90^{\circ}$) showed higher figure in Theoretical head Impact Velocity, Post-impact Head Deceleration, Vehicle Damage when Crash, Passenger's Wounds Severity, and every other items than Barrier curbs ($85^{\circ}$). Barrier curbs ($85^{\circ}$) were found to have better Occupant Safety Index. Analysis of Behavior Using Full-Scale Crash Test showed difference depending on the Impact Condition between Barrier curbs ($85^{\circ}$) and Barrier curbs ($90^{\circ}$). Generally, Barrier curbs ($85^{\circ}$) were superior than Barrier curbs ($90^{\circ}$) in terms of protecting the passengers and vehicle damages. When an impact angle increases, Acceleration of Vehicle, Variations of Speed, and Contact Relationship between Wheels and Curbs, two types of curb showed similarity. However, if an impact of an angle decreases, Barrier Curbs ($85^{\circ}$) showed excellence in Driving Safety such as Acceleration of Vehicle, Variations of Speed, and Contact Relationship between Wheels and Curbs.

  • A number of accidents relating to highly toxic hydrogen fluoride (HF) or hydrofluoric acid (HA) release have occurred over fast few decades in Korea. Thus, this study was conducted to investigate the fluoride (F) concentrations in paddy soil and brown rice from 2 different areas where the soils were exposed to HF and HA. In the first case, the HF leakage accident that occurred in 2012 affected the surrounding soils and crops and consequently, crops (rice) affected by HF were unavailable for forage even though F did not accumulate in the soil. For example, at the time of accident, F concentrations in brown rice samples were $33.0-1,395mg\;kg^{-1}$, while F concentrations in soil samples were $155-295mg\;kg^{-1}$ which were less than the Korean standard guideline values of $400mg\;kg^{-1}$. However, after a year, F concentrations in brown rice were observed below the detection limit ($1mg\;kg^{-1}$), although F concentrations in soils were similar with those in 2012. Also, large amounts of wastewater discharges containing HA occurred in 2013 and some agricultural soils exceeded the Korean standard guideline values for F ($400mg\;kg^{-1}$), but soil-plant F transfer was not observed. In conclusion, it was observed that soil to plant transfer of F is unlikely although HF and HA as gas or liquid form can cause direct damage to plants.

  • Objective: This study aimed to ascertain what should be considered in the "Guideline for Clinical Trials with Herbal Medicinal Products for Liver Cancer," by analyzing existing guidelines and clinical trials. Methods: Committee for the development of a guideline, consisting of 6 Korean medicine doctors, reviewed guidelines and clinical trials on using herbal medicine for treating liver cancer. The trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparators, outcomes, and trial design. We then compared the results of our analysis with the guidelines to identify issues we must to consider when following the "Guideline for Clinical Trials with Herbal Medicinal Products for Liver Cancer." Several guidelines for antitumor agents and clinical trials on herbal medicine were obtained from the Ministry of Food and Drug Safety homepage, etc. The search terms were as follows: "liver neoplasms"; "herbal medicine"; "medicine, Korean traditional"; and "medicine, Chinese Traditional.". Results: Ten articles were obtained from pubmed and Embase. There was no guideline for clinical trials on using herbal medicine for treating liver cancer. All the participants in the reviewed articles had primary liver cancer, and the type of intervention varied (e.g., decoction, patches, and capsules. The comparators included placebos and conventional treatments such as chemotherapy. The outcome assessment methods were tumor response, quality of life, survival, and liver function tests. Adverse events occuring during the trial were also evaluated. Conclusion: Findings were derived by reviewing existing guidelines and comparing them with clinical trials on liver cancer and herbal medicinal products. These results will be utilized in the development of the "Guideline for Clinical Trials with Herbal Medicinal Products for Liver Cancer."

  • 최근 인구 고령화에 따른 골다공증 환자의 증가 및 의료기기 시장의 성장으로 인해 엑스선골밀도측정기 시장이 커지고 있으며, 이에 따른 의료기기 허가 심사건수가 증가하고 있다. 의료기기 기술문서는 의료기기의 허가 심사 시 가장 기본이 되는 문서로 필수 제출 첨부자료 중 하나이다. 기술문서는 의료기기 관련 법령 및 고시에 그 근거를 두고 있으며, 의료기기 전반적인 항목을 기술해야하는 만큼 작성자의 전문성이 필요한 항목이다. 하지만 최근 부정확한 작성의 증가로 인한 심사자들의 업무부담이 증가되고 있어 민원 처리 효율이 저하되고 있다. 특히 엑스선골밀도측정기의 경우 식품의약품안전처 기준규격이 없어, 의료기기 제조/수입업체 등에서 시험항목을 설정하는 데 많은 어려움을 겪고 있다. 따라서 본 연구에서는 개선된 제도가 반영된, 엑스선골밀도측정기 기술문서 작성 가이드라인 개발을 위해 첫째, 개선된 제도 운영에 대한 조사, 품목별 의료기기의 제도 적용에 따른 문서 작성 방법 검토, 기 허가된 품목에 대한 허가 및 기술문서 검토를 완료하였다. 둘째, 품목별 시장현황 조사, 적용 가능한 국내 외 규격을 조사 분석하여 품목별 국제조화된 안전성 및 성능평가 시험기준 및 방법을 도출하였다. 마지막으로, 산 연 관 전문가협의체 논의를 거쳐 기술문서 작성 가이드라인(안)을 최종 도출하였다.
