Wave propagation with high transverse deflection could affect the stability of the ball in its trajectory. For low stiffness balls similar to soccer and volleyball balls, the waves are more noticeable in comparison to other balls like ping-pong ball. On the other hand, the soccer balls are under heavy impact loads from shoots and contacting different objects in the field. The maximum recorded speed of a soccer ball after kicking is the 211 km/hr and the average maximum speed is around 112 km/hr. Therefore, in such speeds the aerodynamic forces become important which are directly related to geometrical shape of the ball. In this regard, the wave propagation in soccer ball is examined in the current study using large deformation shear deformable formulations. Classical relations of stress-strain components are taken into consideration along with minimum total energy principle. The final derived relations were solved by using harmonic differential quadrature method. The results are generally presented ion term of phase velocity as function of different influencing parameters of the materials, geometry and mass of the ball.

Background: Breast feeding is considered to be mutually beneficial for both mothers and infants, though the effect of lactation problems on development of breast lesions (whether benign or malignant) is not clear. Objectives: This study was conducted to identify possible relations between lactation problems and benign and malignant breast disease. Materials and Methods: 308 patients referred to two referral breast clinics in Tehran, the capital city of IR Iran, between January 2008 and January 2011, were recruited. They were interviewed by a standard questionnaire regarding breast feeding problems. The study population was classified in 3 major groups; breast feeding without any problem, unwillingness to breast feed according to whether mothers' preference not to feed or some breast problems like mastitis, and finally insufficient milk that caused the mothers to feed their babies with formula. Results: Recruiting binary logistic regression method, mother's unwillingness to feed her child by breast milk, and also breast problems such as mastitis and abscess during lactation period showed significant relation with both benign and malignant breast diseases (p value<0.01). Surprisingly, inadequate milk was not associated with any of these conditions. Conclusions: We concluded that lactation problems which involve normal milk drainage from the breast may play an important role in whether the mother wll subsequently develope both benign and malignant pathologies. In contrast in the situation that the production of the milk is not sufficient and there are no intentional or unintentional problems in drainage of the produced milk, future problems would not be more common.

Objectives: This study aimed to investigate the public cognition and information acquisition route for heavy metals and organic solvents in the general population in order to provide information for the development of public relations materials. Methods: The study was carried out by questionnaire from January to March 2011 by an interview with trained surveyors. There were 700 participants, divided by gender and age. A questionnaire was issued consisting of subjective and objective cognition evaluation items and questions about information acquisition route and preferred information acquisition route for six heavy metals and five organic solvents. Data were expressed as a percentage using the SPSS 23.0 software package. Result: For heavy metals, subjective and objective cognition degrees were higher in the order of lead, mercury, cadmium, and arsenic. They were higher among males than females, and in adults compared to school-age subjects. For organic solvents, both cognition degrees were high in the order of acetone, benzene, and formaldehyde. However, cognition degree by gender and age showed a complex pattern. As a response to information acquisition route, broadcast media had the highest in all ages and genders, followed by word of mouth from neighbors in elementary school children, school education or expert lectures in middle and high school students up to people in their 30s, and print media among those in their 40s to over 60s. There was no difference in the order by gender. As a response to preference for information acquisition route, broadcast media also proved the highest in all ages and genders, followed by school education or professional lectures among those in elementary school and over their 60s, and the internet in other age groups. Females preferred school education or expert lectures and word of mouth from neighbors, while males preferred the internet. In the case of the internet, the ranking was higher for preferred information acquisition route compared with the ranking for information acquisition route. Conclusions: This data on cognition degree, information acquisition route, and preferred information acquisition route according to gender and age can provide basic data for the development of educational and promotional materials for heavy metals and organic solvents exposure management.

In the present, since a five-year plan for economic development which was started in the early 60's has been successfully promoted for a quarter century, with consolidation in a department of social welfare in our country the participation. in economic society for women is more required than any other times. As a professional occupation for women is incereaing through a high-standard specialization, I think the upbringing for productive woman expert who has a strong motive of accomplishment as a developed person as well as a technical and skilful capacity which can be contributed to the growth of organization is very important. So in this study, I am evaluating the technical disposition of character of professional nurses working with hospital and also trying to supply the basic data being served to th extension of a skillful ability as a nurse, understanding the important factor related to it. The research method applied here is that we used 527 of formed questionnaires which were distributed to 7 University and General Hospitals, somewhat large in a scale, located in Seoul as an analytical material. It was performed between October 11, 1988 and October 18, 1988. An implement which was invented by Cho Moo-Sung is used after being amended and supplemented, which can measure the disposition of professional character. The formation of questionnaires of the disposition of character is 26 totally, 10 for Open-disposition, 11 for Active-disposition, 5 for wise-disposition, and it was measured. 'Ye', or 'No' through an one-half-standard and the environment of hospital organization is composed 12 questions from one point of 'Very Good' to 5 points of 'Very Bad.' Collected materials were analysed through an electronic calculation into the average value, the standard deflection, percentage, person correlative number, $X^2-test, m$ stepwise multiple regression. Summarizing the result from this research is as follows; 1. The average age of the subjective person of this investigation is 28.6 and the average career as a nurse is 6.0 years. 2. The Open-disposition that technical nurses showed is mostly half and half. 3. The Active-disposition of professional nurses was discovered affirmative largely and what they said in their questionnaires describes that they are very active answering $88.2\%$ for the disposition of self-control, $87.3\%$ for the people who think the training more seriously. 4. It was found out that the wise·disposition of technical nurse showed $90.7\%$ of 'Yes' about a new alternative of inquisitive question and we can see a progressive and profound aspect here. 5. As technical character of nurses, mutual relations between Active-disposition, Active-disposition, and wise­disposition were very profitably revealed as 0.42 in justice relations and also suggested that relations between Open-disposition, Active-disposition, and wise-disposition are 0.27 and 0.20 respectively. 6. What nurses recognize about the environment of hospital organization is reasonably acceptable while they feel very bad about rewards and punishments showing average 3.1 comparing to average 2.2 about time­control each other. Considering the prosperity of Active-disposition upon the result what I mentioned above, th possibility which is contributed to the productive improvement of hospital organization is very great and I think it can be more developed as a professional woman who has a strong motive of accomplishment, in advance.

Necessity and purpose of this study: In a large number of countries it has been founded that children′s domestic accidents are at great risk year by year In the United States, they publish detailed accident statistics at regular intervals. In Korea. there have been just a few studies on Accidents-At-Home of preschool children. But it can not be said that there have been any systematic statistics about this area. and any study accounting for the relations of home accidents and preschool: children in detail, Therefore, the purpose of this thesis was focused on the inquire of these relations so as to make a little contribution to Korean preschool children′s health and security measures. So, the detail-purposes are to study following questions and to testify following hypothesis. Prob. 1. What the types of accidents of Preschool children, where the place accidents occurred\ulcorner Prob. 2. What the cause of accidents and, the main factors of the cause\ulcorner Prob. 3. How about the number of their children. the disparity of age among their children and mother′s age in each case of accidents\ulcorner hypothesis 1. There will be differences in the density of protection of parents according to the number of their children. hypothesis 2, There will be differences in accident-types and first-aid methods according to parents socio-economic background. Method; This study employed the interviewing survey method, in which 130 preschool children ware random.sampled, who visit hospital to have medical care. These children (from 1 to 6 years olds) were selected at the emergency room of five hospitals in Seoul (Hosp: Severance, Woosok, Medical Center, Hanyang Medical College Hospital and Seoul Medical Col1age Hospital during study-period (from Aug. to Oct, 1973). Four head nurses in above Hospitals were employed as accident members for this study. Concerning research analysis, the method of hypothesis verifying is used. Conclusion: As two American experts on this subject. Dr, Raymond Neuter and Mr. Ross Mc Garland have drawn attention to "minor epidemics of accidents" that could be avoided by fairly simple measures. preschool children′s accidents could be avoided by parents fair attentions. In other words, one of the most common causes of preschool children′s accidents derived from their parent′s inattention. Therefore, one important task on this subject is to instruct the parents fairly about the children′s accidents. Many accidents could be avoided by the exorcist of a little self-discipline. Also, as much the prevention of accidents is important, as the first-aid Is Important and necessary at the case of the accidents. So, the methods of proper first-aid treatment must be emphasized, and must be taught in school, especially in girls school. And there could be other means available for prevention of accidents. Firstly, the public authorities can take legal measures. More stringent safety standards can be made enforceable by law. Building materials and equipment for domestic us: ought to meat minimum safety criteria at all times. Next the public itself has to understand the seriousness of the problem, and here the dissemination of information is of great importance. All mass media should be brought into play to promote greater public awareness of the question. At last, it will be needed to obtain more detailed epidemiological data through additional surveys and statistics after this study.

목적: 최근 의료기관평가제도는 의료의 질에 대한 병원들의 관심을 높게 하고 그것을 향상시키기 위한 활동을 활발히 전개하고 있다. 또한 추가된 항목인 환자의 위험관리에 대해서도 많은 관심을 보이고 있다. 의정부성모병원 핵의학과는 2008년도 PET/CT도입으로 시작된 부서내 리모델링은 과내 구조 및 업무 프로세스에 많은 변화를 가져왔다. 따라서 변경된 구조와 기존의 업무 처리방식은 미처 알지 못하는 위험요인을 내포하게 되었다. 그러므로 영상 검사 과정에서 발생할 수 있는 위험요인을 다각도로 찾고 분석하여, 부서의 특수한 환경에 맞는 위험관리 프로세스와 위험요인 제거업무를 포함한 개선 활동을 목적으로 한다. 실험재료 및 방법: 핵의학과의 새로워진 프로세스를 다각도로 분석하여 첫째, 위험관리 응대메뉴얼을 제작하여 교육후 실제 업무에 적용한다. 결과분석은 전년도 위험사고 발생건수와 개선활동 후 위험사고 발생건수를 비교하였다. 둘째, 위험관리 홍보동영상은 제작 후 검사전 해당 환자에게 상영하였고 그 후 자체 제작된 설문지로 해당 환자 100명에게 만족도 조사를 하였다. 셋째, 위험요소를 개선할 수 있는 시설물 참여형 개선활동을 통해서 위험요소를 제거하였다. 결과: 안전사고 발생건수는 개선활동이후 PET/CT와 감마카메라 영상 검사 모두 검사건수대비 투약오류, 낙상, 충돌 등의 안전사고가 0건으로 조사되었다. 설문조사 결과는 동영상 상영 후 검사진행과정 이해 74%, 불안감해소 81%로 "만족한다"는 결과가 조사되었다. "위험요소에 대해 주의했습니까?" 라는 물음의 경우 PET/CT는 94%, 감마카메라는 89%가 주의했다는 결과로 조사되었다. 개선활동을 통해서 핵의학과내에서의 고객위험관리를 효과적으로 수행할 수 있었다. 결론: 본 개선활동을 통하여 영상 검사 시 산재된 위험요소를 체계적으로 나열하고 분석하는 계기가 되었다. 또한 안전사고에 대처하는 방사선사의 업무방법에서도 기준이 되는 응대메뉴얼을 적용시킨다면 안전사고의 최소화와 안전사고시 체계적인 피드백이 가능함을 알 수 있었다. 위험요소를 알려주는 방법론적인 부분에서도 일상생활에서 쉽게 접할 수 있는 시청각자료로 제공 되었을 때 보다 효과적이였다. 따라서 이런 활동이 지속적이고 세부화 된 업그레이드 작업을 통해서 환자들에게 제작되어 제공된다면 핵의학 검사 이용의 안전성과 편리성에 도움을 줄 수 있으리라 생각된다.

By statistics in August, 2007, currently Korean motors registration number broke through 16 million units. The demand of motors is being increased as time goes on and the demand of parking lot within apartment complex is increased together. Therefore, it is inevitable to expand underground parking lots. Underground parking lots have relatively weaker environment than the ground and physical/psychological problems as distance far away from the main building, fear for vehicle damage and crimes, impure air, darkness and closed feeling take place. Underground parking lots also occupy a lot of area ratio within apartment complex and have a lot of effects on other facilities. Therefore, underground parking lots are neglected for all that underground parking lots have deep relations with satisfaction for public space within apartment complex. Accordingly, the purpose of the study is to make reference materials when underground parking lots are planned by grasping satisfaction of underground parking lots through inhabitants'mental survey and surveying preferential location and requirements of parking lots.
