Objectives: This study assessed the shape and anatomical relationship of the mental foramen (MF) to mandibular posterior teeth in an Indian sub-population. Materials and Methods: In total, 475 existing cone-beam computed tomography records exhibiting 950 MFs and including the bilateral presence of mandibular premolars and first molars were assessed. Images were evaluated 3-dimensionally to ascertain the position, shape, and anatomical proximity of MFs to mandibular teeth. The position and shape of MFs were measured and calculated. The Pythagorean theorem was used to calculate the distance between the root apex of the mandibular teeth and the MF. Results: MFs exhibited a predominantly round shape (left: 67% and right: 65%) followed by oval (left: 30% and right: 31%) in both males and females and in different age groups. The root apices of mandibular second premolars (left: 71% and right: 62%) were closest to the MF, followed by distal to the first premolars and mesial to the second premolars. The mean vertical distance between the MF and the nearest tooth apex calculated on sagittal sections was 2.20 mm on the right side and 2.32 mm on the left side; no significant difference was found according to sex or age. The distance between the apices of the teeth and the MF was ≥ 4 mm (left; 4.09 ± 1.27 mm and right; 4.01 ± 1.15 mm). Conclusions: These findings highlight the need for clinicians to be aware of the location of the MF in treatment planning and while performing non-surgical and surgical endodontic procedures.

Objectives : The aim of this study is to investigate the effect of Acupuncture and Bee-venom acupuncture for patients with chronic whiplash injury. Methods : Subjects were voluntarily recruited by newspapers and internet. Acupuncture(Eo-Hyeol Bang) and Bee-Venom Acupuncture were performed two times a week for 4 weeks. The patients' symptoms were assessed before, after 4 weeks of treatment by Visual Analogue Scale(VAS), Medical Outcome Study(MOS) 36-Item Short-Form Health Survey(SF-36) Results : VAS score was significantly improved after 4 weeks(p<0.05) compared to the pre-treatment. There were significant changes in physical functioning(PF), Social functioning(SF), role-physical(RP), role emotional(RE), mental health(MH), bodily pain(BP) score of SF-36 after 4 weeks(p<0.05), but there were no significant changes in vitality(VT), general health(GH) score of SF-36. Conclusion: This study suggests that Acupuncture(Eo-Hyeol Bang) and Bee-Venom Acupuncture can be applicable to improve symptoms in patients with chronic whiplash injury.
Traumatic brain injury, which can be caused by head trauma, can damage the brain, resulting in physical disorders, such as headache, dizziness, and nausea, as well as mental health problems, such as depression, anxiety, memory loss, and personality changes that reduce a person's quality of life. Therefore, it is important to administer the best treatment at the right time. A 57-year-old patient complained of headache and depression after intracranical hemorrhage caused by a traffic accident. These symptoms are considered to be after effects of brain trauma due to increased pressure on the brain. Herbal medicine was prescribed to release internal brain pressure and acupuncture was applied to ease frontal and occipital head muscle tension. Objective scales were conducted at baseline, and at one month, two months, and four months. It was observed that the degree of headache and depression improved after treatment. This study is meaningful in that it found that Korean medicine treatments help alleviate the after effects of traumatic brain injury.

Objectives : This study was undertaken to identify the clinical and psychological characteristics in patients of mental disability assessment following traumatic brain injury who had the finding with or without abnormal brain imaging study. Methods : A consecutive series of 59 patients were assessed in hospital from January 1994 to December 1998. Patients were divided into 2 groups based on normal or abnormal brain imaging and the two groups were compared in demographic characteristics, psychiatric symptoms, type of head injury, clinical psychological findings. There were 27 patients with abnormal findings and 32 with normal findings in brain imaging study. Results : Abnormal finding group in brain imaging study had significantly higher incidence of psychosis, decreased memory, decreased appetite, increased nihilistic idea, and intracranial hemorrhage. Also, abnormal finding group showed significantly lower level of performance on the block design subtest of K-WAIS and had significantly lower scores on F, hypochodriasis, depression, hysteria, psychopathic deviate, psychasthenia and schizophrenia subscale of the MMPI. Conclusion : The findings suggest that the patients undergone brain surgery due to intracranial hemorrage at that time of brain injury may have higher frequency of abnormal findings in brain imaging study, complain more cognitive and affective symptoms, and have lower the abstract concept formation and perceptual organization abilities.
Objectives: This study was intended to see the relationship between psychiatric consequences and injury severity following traffic accidents. Methods: We surveyed the 134 patients who were hospitalized from 1994 to 2003 at Chosun University Hospital for psychiatic disability evaluation following traffic accident. We reevaluate demographic factors from admission note. Psychiatric symptoms from mental status exam in medical records. Psychological tests(MMPI, BAI, BDI, K-WAIS) were done. Then we calculate the injury severity score and McBride's rate of disability due to diagnosis from emergency care hospital records. Their relationships were evaluated by statistical methods which were t-test and Pearson correlation analysis using SPSS-10. Results: When physical injury was not severe, suicidal attempt was more frequent and depression, hysteria, psychasthenia, psychopathic deviation subscales were high in MMPI. But when physical injury was severe, they have diffficulty in concentration, impaired orientation, and changed in IQ score. There was no relationship between physical injury severity and faking bad scales(F, Ds-r). Conclusion: We must not assume when physical injury was not severe, the severe sympomts are just faking for their benefit.
The purpose of this study was to examine the oral injury experiences of sport players in a bid to raise awareness of the gravity of problems related to oral injuries and the necessity of mouth guards geared toward preventing mental, physical and economic loss triggered by oral injuries. The subjects in this study were 290 sport players. After their oral injury experiences and use of mouth guards were checked, the following findings were given: 28.6 percent had suffered an oral injury. But just 33.8 percent received education about how to cope with an oral injury. 93.4 percent had never used a mouth guard, and only 25.9 percent felt the need for that. And just 28.3 percent had an intention to use it. felt the need for that. And just 28.3 percent had an intention to use it. Concerning the impact of gender, the female players used more mouth guards. The players didn't use mouth guards a lot regardless of oral injury experiences and education about that, and there was no change in the way they looked at mouth guards, either. The findings of the study illustrated that sport players as well as non-players weren't aware of the importance of mouth guards, though sport players were exposed to the danger of an oral injury all the time. Not only players but non-players should learn about the seriousness of an oral injury, and the necessity of oral guards should be stressed to prevent it.

Recently, nonsuicidal self-injury (NSSI) has been increasing considerably in school counseling. According to the Youth Counseling and Welfare Development Institute, the number of counseling support for NSSI adolescent in 2018 was more than three times higher than the previous year, and the average time when NSSI behavior first appeared was 12.43 years old. As such, adolesnect NSSI continues to increase in recent years, and the age is also gradually decreasing. Nevertheless, research on the motives and characteristics of NSSI among domestic adolescents is still insufficient. This may be attributed to the difficulty of conducting research because self-injury behavior is secretly performed. However, it is also true that this reality has another limitation in the school field, which urgently requires counseling intervention and prevention of students' mental health problems. In addition, counseling for self-injury in the school scene is the biggest cause of exhaustion for counselors because they are under very great stress to cope with repeated self-harm in the dual role of counselors and teachers in school situations. Therefore, this study examines the causes and characteristics of involuntary self-injury through previous research analysis, and examines various difficulties experienced as a school counselor, as well as the effective intervention method of non suicidal self-injury in school counseling.
Purpose: This study examined the socio-demographic factors, the disaster related factors, the physical health related factors and the psychological factors of older adults exposed to natural disaster and these factors may possibly cause the occurrence of PTSD. Methods: A cross-sectional study was designed using the secondary data from the 3rd Disaster Victims Panel Survey (2012-2017). The data from 1,397 disaster victims were analyzed using descriptive statistics and logistic regression analysis. Results: Compared with the younger adult disaster victims, the elderly were more likely to have symptoms of PTSD (15.0% vs. 12.1%). Factors such as the number of years since being exposed to the disaster, anxiety, depression and social adjustment were significantly associated with occurrence of PTSD for both older and younger adults. Female gender was the additional risk factors for the older adults, while marital status, income, having witnessed another person's injury or death, and having lost a home were associated with the occurrence of PTSD. Conclusion: The elderly were more likely to develop PTSD as compared with younger adults. More targeted post-disaster mental health services to the elderly with the symptoms of depressive, anxiety and impaired social adjustments, should be provided to improve their mental health.

Objective : Unclear mental state is one of the major factors contributing to diagnostic failure of occult skeletal trauma in patients with traumatic brain injury (TBI). The aim of this study was to evaluate the overlooked co-occurring skeletal trauma through whole body bone scan (WBBS) in TBI. Methods : A retrospective study of 547 TBI patients admitted between 2015 and 2017 was performed to investigate their cooccurring skeletal injuries detected by WBBS. The patients were divided into three groups based on the timing of suspecting skeletal trauma confirmed : 1) before WBBS (pre-WBBS); 2) after the routine WBBS (post-WBBS) with good mental state and no initial musculoskeletal complaints; and 3) after the routine WBBS with poor mental state (poor MS). The skeletal trauma detected by WBBS was classified into six skeletal categories : spine, upper and lower extremities, pelvis, chest wall, and clavicles. The skeletal injuries identified by WBBS were confirmed to be simple contusion or fractures by other imaging modalities such as X-ray or computed tomography (CT) scans. Of the six categorizations of skeletal trauma detected as hot uptake lesions in WBBS, the lesions of spine, upper and lower extremities were further statistically analyzed to calculate the incidence rates of actual fractures (AF) and actual surgery (AS) cases over the total number of hot uptake lesions in WBBS. Results : Of 547 patients with TBI, 112 patients (20.4 %) were presented with TBI alone. Four hundred and thirty-five patients with TBI had co-occurring skeletal injuries confirmed by WBBS. The incidences were as follows : chest wall (27.4%), spine (22.9%), lower extremities (20.2%), upper extremities (13.5%), pelvis (9.4%), and clavicles (6.3%). It is notable that relatively larger number of positive hot uptakes were observed in the groups of post-WBBS and poor MS. The percentage of post-WBBS group over the total hot uptake lesions in upper and lower extremities, and spines were 51.0%, 43.8%, and 41.7%, respectively, while their percentages of AS were 2.73%, 1.1%, and 0%, respectively. The percentages of poor MS group in the upper and lower extremities, and spines were 10.4%, 17.4%, and 7.8%, respectively, while their percentages of AS were 26.7%, 14.2%, and 11.1%, respectively. There was a statistical difference in the percentage of AS between the groups of post-WBBS and poor MS (p=0.000). Conclusion : WBBS is a potential diagnostic tool in understanding the skeletal conditions of patients with head injuries which may be undetected during the initial assessment.
Safety in sports is important because if an athlete has an accident, he may not be able to lead an everyday life for the rest of his life. The safety of sports facilities is very effective in creating people's sports activities, with the benefits of staying away from physical injury, enjoying sports, and mental peace. Everyone has the right to participate in sports and recreation and to ensure that they want a safe environment. This study prepares a very good Nickel-Cobalt -Silicon carbide (Ni/Co-SiC) nanocomposite with convenient geometry on the leg press machine rod, employing the pulse electrodeposition technique to reduce the rod's wear and increase the durability of sports equipment and control sports damages. The results showed that the Ni/Co-SiC nanocomposite formed at 2 A/dm2 shows extraordinary microhardness. The wear speed for the Ni/Co-SiC nanocomposite created at 4 A/dm2 was 15 mg/min, showing superior wear resistance. Therefore, the Ni/Co-SiC nanocomposite can reduce sports equipment's wear and decrease sports injuries. Ni-Co/SiC nanocomposite layers with various scopes of silicon carbide nanoparticles via electrodeposition in a Ni-Co plating bath, including SiC nanoparticles to be co-deposited. The form and dimensions of Silicon carbide nanoparticles are watched and selected using Scanning Electron Microscopy (SEM).
