본 연구의 목적은 치위생학과 학생과 타 학과 학생의 결핵(Tuberculosis) 감염에 대한 지식과 태도 및 예방 행위 사이의 관계를 확인하는 것으로 하였다. 일반적 특성은 백분율을 구하였고, 결핵에 대한 지식, 태도, 예방행위의 관련성 분석은 상관관계분석을 실시하였다. 연구 결과 치위생학과 학생들의 결핵 감염에 대한 평균점수는 지식 13.56점, 태도 45.75점, 예방행위 41.75점 이었다. 타 학과 학생들의 결핵 감염에 대한 평균점수는 지식 12.93점, 태도 45.58점, 예방행위 42.01점 이었다. 두 그룹 학생들의 결핵에 대한 지식에서 예방행위에 미치는 태도의 매개효과 결과, 학생들의 결핵지식은 태도에 영향을 미치지만 예방행위에는 영향을 미치지 않고, 태도는 예방행위에 영향을 미치는 것으로 나타나 학생들의 결핵 감염에 대한 예방행위를 향상시키기 위해서는 지식과 태도의 조정이 필요할 수 있다. 본 연구는 학생들의 결핵 감염 예방을 위한 교육 프로그램에 활용될 수 있을 것이다.

Objective : The endocrine dysfunction after the operation for suprasellar arachnoid cysts is not rare. The careful operation to prevent structures can prevent this complication, but it is not enough and effective to prevent it. Authors present technical surgical considerations to prevent this complication with a review of our suprasellar arachnoid cyst patients who had postoperative endocrine dysfunction. Methods : From January 2002 to December 2009, eight patients who had suprasellar arachnoid cysts with visual impairment underwent surgery. The mean age was 57.1 years (range, 33-77). Preoperatively, their endocrine function was clinically normal, and laboratory hormonal levels were within normal ranges. Cyst fenestration was performed by craniotomy (n=6) or by a neuro-endoscopic procedure (n=2), and, simultaneously, along with a cyst wall biopsy. Results : The surgery was uneventful in all eight patients, and there were no neurological morbidities. However, in four patients, endocrine dysfunction occurred postoperatively. We compared these four patients (group A) to the other 4 patients without endocrine dysfunction (group B) with intraoperative findings and with the histopathological findings of the cyst wall biopsy. The group A patients had more abundant vasculature on the cystic wall than the group B patients according to both the intraoperative findings and the histopathological findings. Conclusion : When performing a surgical cyst wall fenestration, surgeons should try to minimize the destruction of the cystic wall vasculature and not to make the fenestration at a site that contains many vascular striae.

Even though continuous management and supervision of reinforcement of policies to safeguard accidents at workplace and work sites were implemented. Accident prevention activities such as inspection and diagnosis are urgently required to induce a preliminary investigation to identify the risk factors for each type of work, before the work task to eliminate risks at the worksites. Since safety inspections at work sites were generally conducted through visual inspections, the results of safety inspections may vary depending on the findings and proficiency of the safety officers. The results of those inspections may have loopholes to prevent potential accidents at work. Therefore, the purpose of this study was to develop a risk identification checklist that can effectively perform safety inspections to prevent accidents at work sites. This study initially analyzed the previously developed accident checklist to identify current complications and issues in safety checklists. Based on the findings of major industrial accidents over the past three years, the relationship between accident, workplace, and work type were analyzed refereeing the safety inspection standards. A risk recognition-checklist was developed to provide basic data on identifying risk factors, and inspection guidance at work sites. To prepare for potential accidents by identifying and taking countermeasures to mitigate the high risk and serious accidents at sites by the guidelines of the checklist. The developed inspection checklist has been practically used by experts at work sites to perform safety inspections, and it has been verified its suitability, and feasibility, to prevent or mitigate workplace accidents, including securing the safety and health of field workers. The role of the developed safety checklist has been considered effective at worksites.

Dental caries is the first disease to cause the pathological extraction of teeth in children. The complete prevention of dental caries is not achieved by toothbrushing alone. The use of fluoride and pit and fissure sealant is regarded as key tools to prevent dental caries. Fluoride-containing tablets or multi-vitamins and community water fluoridation can be used as systemic application techniques. Professional fluoride application, fluoride iontophoresis on teeth, fluoride mouth rinsing and fluoride-containing toothpaste can be used as local application techniques. Pit and fissure sealant is mainly used to prevent dental caries on occlusal surfaces of premolars and molars. Sweeteners not to occur dental caries has been developed to substitute sucrose. Dental erosion increases according to the high consumption of acidic soft drink or beverages. The appropriate use of fluoride and pit and fissure sealant are recommended to prevent dental caries effectively and the education is required to reduce the consumption of acidic soft drinks or beverages to decrease dental erosion.

A turnout serves to switch train from one line to another. The turnout consists of a Point which is switchs the rail to induce direction, and a Crossing which is cross over two line on the plane surface, and a Lead where is middle section in Point to Crossing. Point machine, consists of a turnout, is important facilities in railway signal, that is safety issue relates in derailment of the train. Recently, train delay and accident frequently occurred because of the turnout include in a point machine trouble of electrical and mechanical. So in order to prevent train accident the research is advanced, install of normal and reverse indication lamp in a point machine, development of adherence detector for sensing the status of adhesion between the stock rails and tongue rails etc. In this paper investigates the problem which is connected with a turnout trouble, include in a point machine, occurrence at the time of train accident, and then proposed to the safety system model in order to prevent the train accident in turnout.

The humidifier disinfectant disaster (HDD) was not a simple poisoning accident by biocides, but a singular disaster in history created by chemicals in household products. This disaster was a result of the failure of a system for the management of chemical and product safety. Since the management authority for chemical usage safety is different from those for chemical safety in products, many blind areas for chemical safety management in products still remain. The 'Act on the Registration and Evaluation, etc. of Chemical Substances (ARECS)' or the new 'Biocidal Product Act' must not only address the blind areas in the management system for chemical and product safety, but also prevent a second HDD. To prevent another HDD, an integrated registration, evaluation, and management system for chemicals and consumer products must be incorporated into the 'ARECS' as an essential part for chemical safety in consumer products.

As there are more accidents which are more serious in construction site than other industries, it needs the safety management system to be SLIM on the same time, there are still lots of difficulties to prevent those accidents exactly, so it also needs a safety supervision team to prevent the accident, unsafe operation and condition before happening, which is also called as a Man-to Man safety management method. The range of the job site in one personnel's management is very big and large, so it needs the personnel to deep watch the safety operation and prevent any unsafe/fire accidents; the personnel also should find out the unsafe points in the job site, and carefully supervise the dead angle site, then support the totally safety management POINT and realize the ZERO accident.

Recently, new variants of Ransomware are becoming a new security issue. Ransomware continues to evolve to avoid network of security solutions and extort users' information to demand Bitcoin using social engineering technique. Ransomware is damaging to users not only in Korea but also in all around the world. In this thesis, it will present research solution to prevent and cope from damage by new variants Ransomware, by studying on the types and damage cases of Ransomware that cause social problems. Ransomware which introduced in this paper, is the most issued malicious code in 2016, so it will evolve to a new and more powerful Ransomware which security officers cannot predict to gain profit. In this thesis, it proposes 4 methods to prevent the damage from the new variants of Ransomware to minimize the damage and infection from Ransomware. Most importantly, if user infected from Ransomware, it is very hard to recover. Thus, it is important that users understand the basic security rules and effort to prevent them from infection.
