Background : Constipation is can refer to bowel movements that are rare or hard for pass. Constipation is common symptom in current people and the treatment of constipation focused on the use of medicines or physical intervention. The aim of this study are investigates the effects of modified-extracts of Salicornia herbacea (S. herbacea) L. on constipation model. Methods and Results : To investigate the effect of these extracts on constipation model with Sprague-Dawley rats by loperamide administration, we orally administered various dosage of modified-extracts of S. herbacea. L. Then, we checked constipation-related parameters such as fecal number, colon weight, colonic transmit length, colon length as compared to the controls and ameliorated in a dose dependent manner. The results indicated that modified-extracts of S. herbacea. L. was ameliorated constipation in SD rat model. Conclusion : Based on the results, modified-extracts of S. herbacea L. and its many ingredients were considered to have effects on constipation.

The objective of this paper is to investigate into characteristics of the impact energy absorption of ISB panels for the case of the free boundary conditions. In order to examine into characteristics of the impact energy absorption, drop impact tests have been performed. Through the results of the impact tests, The absorbed impact energy per weight, the deformation characteristics of the ISB panels have been quantitatively examined. The experimental results of the ISB panels have been compared to that of SPFC 780 sheet. The impact energy of the tests ranges from 37.1J to 109.1J. From the results of the experiments, it has been shown that ISB panels have a high absorbed impact energy per weight about 9% in comparison with SPFC 780 sheet.

Purpose: The medical staff of the radiation exposure awareness about analyzes the factors that affect for excessive psychological anxiety and just a ploy to get proper recognition for radiation, and produced promotional material for the radiation exposure is also recognized for improvement and training, should we wish to using of as the basis for it. Materials and Methods: Mobile x-ray inspection of contacts at the intensive care unit(ICU), operating room(OR), emergency room(ER), Ward s medical team for 2 occasions questionnaire survey through. Promotional material in order to learn to read before and after the second round of the survey respondents of cognitive maps of the promotional material for only 106 read medical staff. From March until October 2011, Mobile X-ray dose related data collection, questionnaire creation, radiation dose capacity measurement, promotional materials and public relations, said a poll. The questionnaires consisted of six item on the general characteristics, recognition of radiation dose, radiation exposure state and dose management status, to the knowledge of radiation dose, protection and education of radiation dose, radiation safety management situation and status. Some questions were graded on a five point Likert scal. The average and standard deviation were calculated. Results: Primary survey for men and women respectively 27 and 241 persons and in the second survey, males and women respectively 3 and 103 persons. The business-specific distribution Wards(126), OR(115), ICU(103), ER(30). The common attribute is gender, occupations, in career, there was significant difference. Radiation dose awareness also worked to improve the PR later (p<0.05). Radiation exposure and strengthens the dose after promoting the management situation is found (p>0.05). Of protection and education and increased after seeing promotional material (p>0.05). Radiation safety management situation and increase your status after you promote the safety management are strengthened (p>0.05). Business in the operating room by radiation also recognize most, ER>Wards>ICU showed up in the order. Job experience in radiation dose awareness also showed high annual increases and unmarried women. Conclusion: Overall promotional materials because of the perception of radiation bomb and mind in the knowledge that help show the difference, promotional material through the passing of knowledge worked but did not improve the situation. Due to the lack of basic knowledge about radiation, habitual defensive actions, data deficient, the lack of interest, and promote. Therefore, hospital-wide content development and radiation for systemic education for and defense of and publicity needs to be strengthened. 목적: 의료진들의 방사선 피폭에 대한 인지도에 영향을 미치는 요인을 분석하여 방사선 피폭에 대한 과도한 심리적 불안을 해소시키고 방사선에 대한 올바른 인식을 갖도록 하기 위하여 피폭선량에 대한 홍보자료를 제작하여 방사선에 대한 인식도 개선과 교육을 위한 기초 자료로 활용하고자 하였다. 대상 및 방법: Mobile X-선 검사의 접점 부서인 중환자실, 수술실, 응급실, 병동의 의료진을 대상으로 2차에 걸쳐 설문 조사하였다. 홍보자료를 읽기 전과 후에 인식도 변화를 알아 보기 위해 2차 설문지 응답자 중 홍보자료를 읽어본 의료진 106명(42.6%)만을 대상자로 하였다. 2011년 3월부터 10월까지 X-선 피폭 관련 자료수집 및 설문지 제작, 피폭선량 측정, 홍보자료 제작 및 홍보를 하였다. 설문지는 응답자와 관련된 일반적인 특성, 방사선 피폭에 대한 인식도, 방사선의 노출 정도와 피폭관리 실태, 방사선 피폭에 대한 지식, 방사선 피폭의 예방과 교육, 방사선 안전관리 실태 및 현황 등 총 6개 항목으로 구성하였다. 결과: 1차 설문조사 대상자는 남성 27명, 여성 241명, 2차 설문조사에는 남성 3명(2.8%), 여성 103명(97.2%) 이었다. 근무지별 분포는 병동 126명(33.69%), 수술실 115명(30.75%), 중환자실 103명(27.54%), 응급실 30명(8.02%) 순이었다. 대상자의 일반적 특성은 성별, 직종, 연차에서 유의한 차이가 있었다. 방사선 피폭에 대한 인식도는 홍보 후에 개선효과가 있었다(p<0.05). 방사선의 노출 정도와 피폭관리 실태는 홍보 후에 강화하는 것으로 나타났 다(p>0.05). 방사선 피폭에 대한 지식은 홍보자료를 본 후에 증가하였다(p<0.05). 방사선 피폭의 예방과 교육은 홍보자료를 본 후에 증가하였다(p>0.05). 방사선 안전관리 실태 및현황은 홍보 후에 증가하여 안전관리를 강화하는 것으로 나타났다(p>0.05). 근무지에 따른 방사선 인식도는 수술실에서 가장 높았고, 응급실>병동>중환자실 순으로 낮게 나타났다. 업무경력에 따른 방사선 피폭에 대한 인식도는 연차가 증가할수록 높게 나타났다. 방사선 피폭에 대한 전반적인 인식도는 미혼일수록 예민하였다. 결론: 전반적으로 홍보자료로 인하여 방사선 피폭에 대한 인식도와 지식에서 유의한 차이가 있는 것으로 나타났고, 홍보자료를 통한 지식의 전달은 효과가 있었지만 실태는 개선되지 않았다. 원인은 의료진의 방사선에 대한 기본적인 지식과 자료의 부족, 습관적인 방어적 행동, 불충분한 홍보 기간, 관심의 부족으로 사료된다. 결론적으로 방사선 피폭에 대한 막연한 두려움과 공포를 줄이기 위해서는 병원차원에서 콘텐츠를 개발하여 방사선의 위해와 방어에 대한 체계적인 교육을 통한 지식과 정보 제공 및 홍보를 강화해야 한다고 생각한다.

The objective of this paper is to investigate the influence of impact conditions on the impact characteristics of the SPFC 780 sheet for the case of the free boundary conditions. In order to examine impact characteristics of the sheet, three-dimensional finite element analyses have been performed. High speed tensile tests have been carried out to obtain strain-stress relationships including the effects of the strain rate. Through the comparison of the results of FE analyses and that of impact tests, an accurate FE model has been developed. In order to reduce error range of load and displacement, the hyper-elastic model and the damping factor have been employed. From the results of FE analyses, the variation of stress and strain energy in the SPFC 780 sheet has been quantitatively examined.
