STATEMENT OF PROBLEM: Implant drivers are getting popular in clinical dentistry. Unlike to implant systems with external hex connection, implant drivers directly engage the implant/abutment interface. The deformation of the implant/abutment interface can be introduced while placing an implant with its implant driver in clinical situations. PURPOSE: This study evaluated the change of rotational freedom between an implant and its abutment after application of different insertion torques. MATERIAL AND METHODS: Three kinds of internal connection implants were utilized for the current study (4.5 x 12 mm Xive, 4.3 x 11.5 mm Inplant Magicgrip, 4.3 x 12 mm Implantium MF). An EstheticBase, a 2-piece top, a Dual abutment was used for its corresponding implant system. The rotational freedom between an implant and its abutment were measured before and after applying 45, 100 Ncm insertion torque. Repeated measures ANOVA was used for statistical analysis. RESULTS: Under 45 Ncm insertion torque, the rotational freedom between an implant and its abutment was significantly increased in Xive (P = .003). However, no significant change was noted in Inplant Magicgrip and Implantium MF. Under 100 Ncm torque, both in Xive (P = .0005) and Implatium MF (P = .03) resulted in significantly increased rotational freedom between the implant and its abutment. DISCUSSION: The design of the implant/implant driver interface effectively prevented the deformation of implant/abutment interface. Little change was noted in the rotational freedom between an implant and its abutment, even though the insertion torque was far beyond clinical application. CONCLUSIONS: The implant/abutment joint of internally connecting implants were quite stable under insertion torque in clinical situation.

STATEMENT OF PROBLEM: Repeated delivery and removal of abutment cause some changes such as wear, scratch or defect of hexagonal structure. It may increase the value of rotational freedom(RF) between hexagonal structures. PURPOSE: The purpose of this study was to evaluate surface changes and rotational freedom between the external hexagon of the implant fixture and internal hexagon of abutment after repeated delivery and removal under SEM and toolmaker's microscope. MATERIALS AND METHODS: Implant systems used for this study were 3i and Avana. Seven pairs of implant fixture, abutment and abutment screws for each system were selected and all fixtures were perpendicularly mounted in liquid unsaturated polyesther with dental surveyor. Each one was embedded beneath the platform of fixture. Surfaces of hexagonal structure before repeated closing and opening of abutment were observed using SEM and rotational freedom was measured by using toolmaker's microscope. Each abutment was secured to the implant fixture by each abutment screw with recommended torque value using a digital torque controller and was repeatedly delivered and removed by 20 times respectively. After experiment, evaluation for the change of hexagonal structures and measurement of rotational freedom were performed. RESULT: The results were as follows ; 1. Wear of contact area between implant fixture and abutment was considerable in both 3i and Avana system. Scratches and defects were frequently observed at the line-angle of hexagonal structures of implant fixture and abutment. 2. In the SEM view of the external hexagon of implant fixture, the point-angle areas at the corner edge of hexagon were severely worn out in both systems. It was more notable in the case of 3i systems than in that of Avana systems. 3. In the SEM view of the internal hexagon of abutment, Gingi-Hue abutment of 3i systems showed severe wear in micro-stop contacts that were machined into the corners to prevent rotation and cemented abutment of Avana systems showed wear in both surface area adjacent to the corner mating with external hexagon of implant fixture. 4. The mean values of rotational freedom between the external hexagon of the implant fixture and internal hexagon of abutment were 0.48+/-0.04 degrees in pre-tested 3i systems and 1.18+/-0.25 degrees after test, and 1.80+/-0.04 degrees in pre-tested Avana systems and 2.61+/-0.16 degrees after test. 5. Changes of rotational freedom after test showed statistically a significant increase in both 3i and Avana systems(p<0.05, paired t-test). 6. Statistically, there was no significant difference between amount of increase in the rotational freedom of 3i systems and amount of increase in that of Avana ones(p>0.05, unpaired t-test). CONCLUSION: Conclusively, it was considered that repeated delivery and remove of abutment by 20 times would not have influence on screw joint stability. However, it caused statistically the significant change of rotational freedom in tested systems. Therefore, it is suggested that repeated delivery and remove of abutment should be minimal as possible as it could be and be done carefully. Additionally, it is suggested that the means or treatment to prevent the wear of mating components should be devised.

PURPOSE: To evaluate the performance of a newly-designed ultrasound (US)-guided puncture device. MATERIALS AND METHODS: A newly-designed US-guided puncture device was composed of a guide segment and an attachable segment. The guide segment allowed the needle to be placed in the plane of US view with a maximal degree of freedom, and the attachable segment was designed to attach to most convex US probes. Six operators punctured 144 targets in phantoms using either the new device (n = 72) or free-hand technique (n = 72). The number of required needle passages and the necessary procedure times were compared between the two groups. RESULTS: The number of required needle passages and the necessary procedure time were significantly reduced in five operators when the newly-designed US-guided puncture device was used (p < 0.05). CONCLUSION: A newly-designed US-guided puncture device, which allows for a maximal degree of freedom in needle placement and can attach to most convex US probes, showed good performance in our study.

OBJECTIVES: Nail salon owners in New York City (NYC) are required to provide their workers with gloves and it is their responsibility to maintain healthy, safe working spaces for their employees. The purpose of this study was to determine the frequency with which nail salon workers wear protective gloves. METHODS: A Freedom of Information Law request was submitted to New York Department of State's Division of Licensing Services for a full list of nail salons in Manhattan, NYC. A sample population of 800 nail salons was identified and a simple random sample (without replacement) of 30% (n=240) was selected using a random number generator. Researchers visited each nail salon from October to December of 2015, posing as a potential customer to determine if nail salon workers were wearing gloves. RESULTS: Among the 169 salons in which one or more workers was observed providing services, a total of 562 workers were observed. For 149 salons, in which one or more worker was observed providing services, none of the workers were wearing gloves. In contrast, in six of the salons observed, in which one or more workers was providing services, all of the workers (1 in 2 sites, 2 in 1 site, 3 in 2 sites, and 4 in 1 site) were wearing gloves. Almost three-quarters of the total number of workers observed (n=415, 73.8%) were not wearing gloves. CONCLUSIONS: The findings of this study indicate that, despite recent media attention and legislation, the majority of nail salon workers we observed were not wearing protective gloves when providing services.

Press freedom and worldwide internet access have opened ample opportunity for a staggering number of poor open access journals and junk publishers to emerge. Dubious publishers are abusing and camouflaging the golden open access model. In 2012, Jeffery Beall shed light on the predatory journals (as he preferred to call them) and the threat to open access scientific publication. Publishing in predatory journals is continuing to be a major threat for the development of science in developing countries. The authors of this article proposed solutions and outline a fresh perspective to help authors avoid publishing in predatory journals.

The study seeks to widen the discussion from healthcare oriented ‘health publicness’ to human security oriented ‘health publicness’. The shortcomings of previous literatures on health publicness are as follows: (1) the studies have confined the range of discussions to healthcare system, (2) lacked arguments from political perspectives, and (3) failed to provide actionable pathways to achieve the goal. Thereby, we suggest ‘health publicness’ based on the concept of human security to solve multidimensional healthcare problems. The health publicness based on human security, which aims to secure everybody's freedom from want and fear, enables not only to expand the scope of health problems that can be discussed but also to propose the procedures to achieve health publicness. More specifically, it consists of substantive and procedural health publicness. The former is about ‘health security’-protecting, maintaining, and promoting individual's health-whereas, the latter is about ‘social dialogue’ guaranteeing participation of citizens, government, employers, and worker representatives. In conclusion, this study proposes the ‘Regional Healthcare Quadripartite’ as the incarnation of health publicness involving a variety of actors within and across the healthcare system.

A press release recently reported a case in which legal decisions, regarding the stay of execution of a criminal sentence, and the extension of this stay, were made based on medical certificates, containing a definitive medical history, prepared and issued by a family doctor. Thereafter, the family doctor who prepared these medical certificates was accused of being guilty of a crime related to the preparation of a number of false medical certificates and has been subject to adjudication for this crime. Under the circumstances, having recognized that a medical certificate would be considered the significant basis for making a decision regarding the determination of damages of a civil nature and the determination of confinement in cases of a criminal nature, as well as of the stay of execution of sentences related to the restriction of physical freedom, a doctor is required to accurately describe a patient's medical status and other general facts when preparing a medical certificate, and if a doctor has cooperated with other specialists during the treatment of a specific disease, the medical certificate is required to honor and reflect such specialists' judgment. Furthermore, information regarding either a patient's previous treatment history or any complications developed in the future is to be included in a medical certificate only when these matters are directly related to the patient's current health status from a clinical perspective.

PURPOSE: This study was done to provide fundamental ontological understanding of caring and inquiring into the possibility of a caring practice in nursing based on existential phenomenology. METHODS: According to Heidegger's existential phenomenology, caring has been interpreted as a fundamental ontological basis for caring practice in nursing. Further, based on Merleau-Ponty's phenomenology, the meaning of the lived experience of illness and the way of caring practice have been described from the aspect of the existential involvement in the embodied life world. RESULTS: Heidegger's phenomenology provided ontological thinking about caring, which is understood in a basic way as the possibility of human existence and dwelling in oneself in the confrontation of the illness experience. Merleau-Ponty's phenomenology offered a meaning of human existence according to bodily intention and situated freedom in the life world. This perspective of embodiment enables nurses to understand bodily experiences of patients and recovery of their bodily capacity in responding to the situation in caring practice. CONCLUSION: Existential phenomenology gives insight into fundamental reflection for caring attitude and practice in nursing. Existential phenomenological nursing research can provide descriptions and meaning of the lived experience of illness and a way of coping with the crisis of human existence in caring practice.
