  • Biomedical metal implants have been used clinically for replacement, restoration, or improvement of injury bodies based on high mechanical properties, but it has some risks such as the inflammatory, late thrombosis, or restenosis due to the low biocompatibility and toxicity. In various techniques of surface treatment developed to preserve these drawbacks, this study examined the electrospray coating technology with biodegradable poly (lactic-co-glycoic acid) (PLGA) on metal surface. Based on fundamental examination of electrospraying and solution parameters, the surface morphology of coated film was closely related to the boiling point of solvent, in-flight distance, and droplet size. The thickness of polymer film was linearly proportional to the emerged volume. This result exhibits that the polymeric droplets were continuously deposited on the polymer film. Therefore, the electrospray coating technology might be applied into the fabrication of single/multi-layered polymer film in nano-/micro-thickness and the control of the topology for biomedical metal implants including stents.

  • Constitutional trisomy 8 is a relatively rare aneuploidy; most identified cases are mosaic with a normal cell line. The phenotype is highly variable from apparently normal to severe disability. The proportion of abnormal cells is dramatically different between tissues and the severity of the phenotype is not directly related to the level of mosaicism. Therefore, it is very difficult to provide a definitive prognosis. We report here a case of constitutional trisomy 8 mosaicism with agenesis of the corpus callosum, congenital heart disease and micrognathia. The trisomy 8 cell line was not detected by prenatal cytogenetic study. This is the fourth reported case of constitutional trisomy 8 mosaicism in Korea.

  • This study was conducted to observe the changes in radiation exposure dose and image quality of pediatric patients according to the presence and size of the gonadal shield when using the AEC system. X-ray equipment was used to measure the radiation exposure dose in the abdominal and gonads of the pediatric phantom when no shielding body was used and when three different sizes of shielding body were used, and SNR and CNR were measured through the obtained images. As a result of the study, the radiation exposure dose to the gonads decreased in proportion to the size of the radiation shield, but the radiation exposure dose to the abdomen was rather increased, and the image quality did not change. It is recommended to use a shield with a size optimized for the age, weight, and body size of the pediatric patient so as not to be overexposed by the increased radiation due to the radiation shield due to the use of the AEC System. For this purpose, information about the pediatric patient with the nurse It is believed that exchange is necessary.

  • Objectives:The purpose of this study was to evaluate suicidal attitudes, self-image, anxiety and depression on industrial and cultural wemen's high school, and to make a comparative study between suicidal attitudes and anxiety, depression, self-image. Methods:Three hundred twenty-six student(161 persons from industrial wemem's school, 165 persons from cultural wemen's school), who were supposed to different from in psychosocial environment, entered this study. To assess the attitudes toward suicide, Suicide Opinion Questionnaire(SOQ) were done at study. To estimate anxiety, depression, and self-image, Zung' Self-rating Anxiety Scale (ZAS), K-Beck Depression Inventory(KBDI), Offer's Self Image Questionnaire(OSIQ), respectively, were executed in this study. Results:1) We extracted 5 factors after factor analysis based on SOQ results with the response of the 326 subject;ethics, religion, mental illness, acceptability, revenge. Revenge factor were stastically significant between both groups. 2) In OSIQ, family relationship factor & superior adjustment factor were stastically significant between both groups, but, both groups didn't have a significance on ZAS & KBDI. 3) According to correlative analysis between SOQ results and OSIQ, ZAS, KBDI results, ethics factor(SOQ) were converse to BS factor, ET factor, and ME factor in OSIQ. Mental illness factor(SOQ) were in proportion to PP factor(OSIQ). Acceptability factor(SOQ) were in proportion to ZAS & KBDI result. Conclusion:Our subject mostly regarded suicide as sinful ethically ,and as mental illness. But, In that there was neuropsychiatric history and suicidal idea in them, the subjects looked upon suicide as permissive. With significantly high score on ZAS & KBDI, there were more acceptable attitude toward suicide. So, We consider suicide to be used as coping strategy about more stressful event to young adolescent.

  • In Korea, exposure to stress has been accompanied by mental pain in the process of achieving many growth along with rapid development, various social problems, and the frequency of emergency hospitalization is increasing.. In the case of mentally ill patients, "unwanted hospitalization" is a problem, and police and 119 paramedics try to suppress the body of mentally ill patients, and many problems are exposed This is because the constituent requirements of the provisions of emergency hospitalization under the Mental Health and Welfare Act do not reflect reality, and each institution has a different position on one mentally ill person, and emergency hospitalization does not proceed smoothly or leads to friction between related organizations, and the safety of the mentally ill or others is not secured. Emergency hospitalization is defined as "a person who finds a person who is presumed to be mentally ill and is at high risk of harming his or her health or safety or others," and if the situation is so urgent that he or she cannot afford time to go through the hospitalization procedure to decide on his or her own hospitalization, he or she can request emergency hospitalization with the consent of a doctor and a police officer. In this case, 119 paramedics are escorted to a psychiatric institution. This provision of emergency hospitalization poses many problems in the process of transferring to psychiatric institutions. If a police officer or 119 paramedics in charge of practice use "physical force" during the emergency hospitalization process, side effects will inevitably occur, and professional negligence can be a problem. Specifically, when exercising physical force, the minimum necessary physical restraint based on laws and regulations and proportional principles is required, and the lack of the duty of care of 119 paramedics or police officers under the laws and regulations will eventually be resolved by applying other laws and regulations. Accordingly, it will be an opportunity for mentally ill patients to be transferred to psychiatric institutions in a safe environment by changing the subject of emergency hospitalization provisions under the Mental Health Welfare Act, defining and prescribing the use of physical protection guards as the enforcement regulations of the Mental Health Act, setting the duty of care for 119 paramedics and police officers, and creating an environment for transportation so that mentally ill patients can be treated safely.

  • Low energy x-rays that occur in the low tube voltage radiography of general radiography are absorbed strongly in the body and do not aid image quality enhancement. This study maintains titer in general radiography while using tube current that are proportional to density and the tube voltage 15% principle according to density to reduce patient exposure doses, and area doses and entrance surface doses were measured to compare patient exposure doses. In hand, knee, abdomen, and skull radiography, kVp was increased to 115% and mAs was decreased to 50% and kVp was decreased to 85% while mAs was increased to 200% and area doses and entrance surface doses were measured to compare relative doses. Also, 5 places in each image were set, density was measured, and Kruskal wallis H test was conducted to observe significance probabilities between groups. To fix density, kVp was increased to 115% and mAs was decreased to 50% and after measurements of mean area doses and entrance surface doses were made by each part, each decreased to 58.68% and 59.85% when standard doses were set to 100%, and each increased to 147.28% and 159.9% when kVp was decreased to 85% and mAs was increased to 200%. Comparisons of density changes showed that hand, knee, abdomen, and skull radiography all displayed significance probabilities>0.05, showing no changes in concentration. Radiography that increases kVp and lowers mAs through reasonable calculations within ranges that don't affect resolution and contrast seems to be a simple way to decrease patient exposure doses.

  • This study is to propose the improvement of security related regulations to reinforce security activity and actualize constitutionalism in the National Assembly. For the purpose, some improvements could be considered as followings; First, legislating of regulations including some articles on the scope of security activity such as order preservation at assembly hall, facility security, security agents' right and protection of personal is necessary. Second, changing the organization and command system of security management is necessary for the unification of security activity and efficiency of the job. Also clear definition of terminology on the security job is need. For the shake of above object, one officer in charge of situation management and three section such as the personal protection section, facility security section and order preservation section could be substructured under security department. Third, elimination of unnecessary article on the arrest of red handed criminal in the assembly hall and on the physical checkup of audience by security agent is need. Also legislating of regulations on the hoarding of person who could disorder is necessary. Forth, legislating of regulations on the cooperation with government branch, judicial police power, carry and use of weapon and uniform and equipment to reinforce practical efficiency of security activity. For the proper legislating of the regulations, comparition with other public organizations such as presidential security Service, police, private security could be considered.

  • The objective of this study was to derive the served distance of the senior-friendly park considering physical changes, which were estimated through a comparison experiment at an actual target site. The time to walk 500m was examined because 500m is considered the served distance of a neighborhood park and as a standard set by the city. The mean walking time of the control group (younger than 65 years) was 536 seconds, while that of the treatment group (older than 65 years) was 889 seconds, which was approximately 1.7 times longer than the control group. The results of this study also showed that the walking time of females was longer than that of males when they were older than 65 years old. The walking velocities of the control group and the treatment groups were also calculated using the mean walking time. The weight estimated by a proportional formula was 0.6. When it was applied to 500m, which is the served distance of a neighborhood park, the served distance of the senior-friendly park was estimated as 300m. Lastly, the green service excluded area was quantified by applying the 300m, the served distance of a senior-friendly park, to the Jung-gu, Daegu, which had the highest elderly population in the Daegu Metropolitan City. The results of this calculation showed that the area served by a city park was $2,425,747m^2$ and the area excluded from the city park service was $4,627,700m^2$ for senior citizens. The results also showed that, in terms of the distributive equity, the administrative districts received unequal am ounts of urban green area services.
