This paper suggests an input device that allows a user not only to naturally interact with education contents in virtual environment but also to sense haptic feedback according to his/her interaction. The proposed system measures a user's motion and then creates haptic feedback based on the measured position. To create haptic information in response to a user's interaction with educational contents in virtual environment, we develop a motion input device which consists of a motion controller, a haptic actuator, a wireless communication module, and a motion sensor. To measure a user's motion input, an accelerometer is used as the motion sensor. The experiment shows that the proposed system creates continuous haptic sensation without any jerky motion or vibration.

This study investigated the relationships between experiencing verbal violence and the emotional responses and coping behaviors of dental hygienists who worked in Jeonju between February 24 and March 18, 2017 to prepare strategies for managing verbal violence and establish a healthy working environment for dental hygienists. The following findings were obtained in this study. The dental hygienists primarily experienced verbal violence from patients and guardians (1.67 points). The most common verbal violence type was, "Someone treated me impolitely." The most common emotional response to verbal violence was "anger" (3.52 points). The coping style of most dental hygienists was problem-focused coping (3.28 points), followed by emotion-focused coping (2.75 points). Most hygienists with the problem-focused coping style stated that they resolve the problem through dialogue (3.51 points), while most hygienists with the emotion-focused coping style responded that they just ignore the situation (3.78 points). The relationship between experiencing verbal violence and the emotional responses and coping behaviors of dental hygienists showed a statistically significant positive correlation (p<0.05) with emotional responses and problem- and emotion-focused coping associated with experiencing verbal violence from dentists, patients, and guardians. These findings confirm the need to reduce verbal violence, control emotional responses after exposure to verbal violence, and use more problem-focused coping measures. Dental hygienists must develop interpersonal skills and communication techniques and promote professionalism in their workplace to protect themselves from verbal violence at work.

The present investigation confirms the zoonotic significance of Microspoum canis infection in five patients who had direct contact with diseased dogs and cats. Typical ringworm type lesions were mainly encountered on the exposed areas of the body. M. canis was isolated from the cutaneous lesions of man ana infected pets ; and also directly demonstrated in skin materials. However, the fungus could neither be recovered from the non-contact group nor from the saprobic environment. The isolates from man, dog, and cat showed similar gross as well as microscopic morphology. Further genetic studies so indicated that all the human and animal isolates of M. canis were(-) mating type. It is believed that transmission of zoophilic dermatophytes from animal to man occurs more commonly with direct exposure. In addition, the epidemiology and preventive measures are also discussed.

Objectives : This study examined the impact of peer's suicide on mental health of middle-school students. The aim of this study was to describe the course of posttraumatic stress and grief reaction, suicide ideation, and depression score among adolescents after exposure to peer's suicide and to examine the relationship between posttraumatic stress and other mental health scores in these subjects. Methods : Thirty seven middle school students who were exposed to the suicidal death of a peer completed self-report measures to assess levels of depression, grief reaction, post-traumatic stress, and suicide ideation at 1 month and 8 months after the peer's suicide. Results : There was no significant change in mental health scores between 1 month and 8 months. Level of posttraumatic stress after 8 months was related to acute grief response. Subjects who experienced a clinically significant level of suicidal ideation and posttraumatic stress showed more mental health problems. Conclusion : The results suggested that peer's suicide strongly impacted mental health issues of adolescents at a critical time of adolescent development. Clinicians should perform a thorough evaluation of mental health problems for youth who experienced peer's suicide and help them in management of their grief reaction.

Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

Due to development of IT, various Internet services via the non-face-to-face are increasing rapidly. In the past, the resident registration numbers (RRN) was used a mean of personal identification, but the use of RRN is prohibited by the relevant laws, and the personal identification services using alternative means are activated. According to the prohibition policy of RRN, i-PIN service appeared as an alternative means to identify a person. However, the user's knowledge-based i-PIN service continues to cause fraudulent issuance, account hijacking, and fraud attempts due to hacking accidents. Due to these problems, the usage rate of i-PIN service which performs a nationwide free personal identification service, is rapidly decreasing. Therefore, this paper proposes a technical safety enhancement method for security enhancement in the i-PIN-based personal identification service. In order to strengthen the security of i-PIN, this paper analyzes the encryption key exposure, key exchange and i-PIN authentication model problems of i-PIN and suggests countermeasures. Through the proposed paper, the i-PIN can be expected to be used more effectively as a substitution of RRN by suggesting measures to enhance the safety of personal identification information. Secured personal identification services will enable safer online non-face-to-face transactions. By securing the technical, institutional, and administrative safety of the i-PIN service, the usage rate will gradually increase.

Quantifying the solute composition of a cloud droplet (or a whole droplet) is an important task for understanding formation processes and heating/cooling rates. In this study, a combination of droplet fixation and SR-XRF microprobe analysis was used to visualize and quantify elements in a micro-scale droplet. In this study, we report the preliminary outcome of this experiment. A spherical micro-scale droplet was successfully solidified through exposure to ${\alpha}$-cyano-acrylate vapor without affecting its size or shape. An X-ray microprobe system equipped at the beam line 37XU of Super Photon ring 8 GeV (SPring-8) was applied to visualize and quantify the elemental composition in an individual micro-scale droplet. It was possible to reconstruct 2D elemental maps for the K and Cl contained in a microdroplet that was dispensed from the 10-ppm KCl standard solution. Multi-elemental peaks corresponding to X-ray energy were also successfully resolved. Further experiments to determine quantitative measures of elemental mass in individual droplets and high-resolution X-ray microtomography (i.e., 3D elemental distribution) are planned for the future.

This study is carried out in order to propose a drought risk assessment methodology. This methodology is required to deal with practical questions that a variety of stakeholder often raise in the course of discussions on mitigation measures. With a focus on the socioeconomic aspect of drought, more particularly, residents' hardship from water scarcity, it suggests basic concepts and a system of methods in order to assess hazard, exposure, vulnerability and risk. The case study shows a considerable possibility of the methodology in evaluating potential levels of damages in a certain area, in identifying the boundary of districts where risk is disproportionately concentrated, and also in understanding the underlying risk factors of those districts. The authors think that the proposed methodology is able to offer risk information in terms of socioeconomic damages, and therefore contribute to reducing information gaps that policy-makers are currently encountered with.
