Objective: Recent studies have shown that repetitive peripheral magnetic stimulation (rPMS) reduces pain in various conditions. This pilot study aimed to investigate the effects of rPMS depending on the pain characteristics. Method: Adult patients aged 19~85 years evaluated at our institution between September 1, 2017 and February 28, 2018 for subacute to chronic musculoskeletal pain equivalent to a numeric rating scale of 3 or higher for at least one month were enrolled. Pain scores as determined using a numeric rating scale at baseline and at the end of treatment were set as the primary outcome. Additionally, we classified the pain into nociceptive, intermediate, or neuropathic pain using the PainDETECT questionnaire and compared the responsiveness to rPMS according to the type of pain. Results: The average pain scores significantly decreased after the 2-week rPMS treatment in all enrolled subjects (p<0.001). There was no statistically significant difference in pain reduction between groups divided by PainDETECT questionnaire. Conclusion: This study suggests that rPMS could safely relieve various types of pain.

The detection of blood at a crime scene is an important process for identification and case reconstruction. However, blood may be difficult to observe with the naked eye on dark or multi-colored surfaces. Acidic hydrogen peroxide (AHP) is a recently reported blood enhancement reagent that can enhance blood with high sensitivity by increasing the exposure time of the camera. However, it has never been compared to previously known techniques on dark or multi-colored surfaces. For this purpose, the method of observation/photographing (UV and IR photography), alginate casting, leuco rhodamine 6G (LR6G), and AHP were applied to bloody impression on dark or multi-colored surfaces and the results were compared. As a result, blood treated with AHP had a higher contrast to the surfaces than UV and IR photography, and it was applicable on all surfaces, opposed to alginate casting. In addition, AHP successfully enhanced blood on dark or multi-colored surfaces, similar to LR6G.

Halitosis is primarily caused by bacterial decay. The bacteria, which originate from biofilms such as dental plaque, show abnormal proliferation due to dental caries, periodontal diseases, soft tissue infections, and tongue diseases. Most studies on halitosis have exclusively focused on gram-negative bacteria in the oral cavity rather than on general oral microorganisms including oral fungi. This study analyzed oral fungal hyphae, as well as distribution and motility of oral microorganisms, and provided basic data on the control of halitosis. Our results revealed that the greater is the number of cocci bacteria, the higher is the halitosis value, or bad breath value (BBV), suggesting that cocci have a strongly positive correlation with halitosis (r=0.379, p=0.030). Moreover, there was no significant difference in the morphology or distribution of motile bacteria and motility score, with respect to BBV. Lastly, we investigated the relationship between halitosis and oral fungal hyphae. We found that a higher BBV corresponded with a greater number of fungal hyphae and that patients with fungal hyphae scored a higher BBV. However, this result was not statistically significant. In conclusion, this study provided the preliminary data on oral microorganisms and halitosis, but further studies are needed to analyze the relationship between oral microorganisms and halitosis.

As the computerization of hospitals becomes more advanced, security issues regarding data generated from various medical devices within hospitals are gradually increasing. For example, because hospital data contains a variety of personal information, attempts to attack it have been continuously made. In order to safely protect data from external attacks, each hospital has formed an internal team to continuously monitor whether the computer network is safely protected. However, there are limits to how humans can monitor attacks that occur on networks within hospitals in real time. Recently, artificial intelligence models have shown excellent performance in detecting outliers. In this paper, an experiment was conducted to verify how well an artificial intelligence model classifies normal and abnormal data in network traffic data generated from medical devices. There are several models used for outlier detection, but among them, Random Forest and Tabnet were used. Tabnet is a deep learning algorithm related to receive and classify structured data. Two algorithms were trained using open traffic network data, and the classification accuracy of the model was measured using test data. As a result, the random forest algorithm showed a classification accuracy of 93%, and Tapnet showed a classification accuracy of 99%. Therefore, it is expected that most outliers that may occur in a hospital network can be detected using an excellent algorithm such as Tabnet.

This is a case report of complete mouth rehabilitation in a patient with generalized attrition and loss of posterior support. After analyzing the condition of the temporomandibular joint, multiple implants were placed to restore collapsed occlusion. Fixture/abutment level intraoral scanning was done instead of using conventional impression materials which entail multiple bite registration for cross-mounting. A 'jaw motion tracking'device, 'digital face-bow transfer', and 'double scan technique' which enables duplicating temporary restoration to definitive restoration were used to fabricate definitive prostheses. By using various digital techniques, complete mouth rehabilitation was done with minimal chair time in a patient with unstable occlusion.

The purpose of this study is to identify the myth(erroneous beliefs) of police, lawyers, and doctors about wife abuse. Subjects included 194 police, 81 lawyers, 164 doctors, and 222 public who lived in Taegu and kyngbuk. The major findings of the study are follows; first, subject-groups commonly have the myth about wife abuse. Second, there are no differences by sex, formal education, and marital status. Additionally significant age differences are found in police and lawyers. Third, especially they have the myth about wife abuse-e.g. battered women could avoid being battered by simply leaving their batters, their husbands can stop the abuse by attending a counseling or therapy session and by deceasing the job-stress, and they must not to divorce for their children.

This study was conducted to evaluate a forecast model designed to describe a vocational high school for runaway students. The study included 2000 adolescents from the KEEP(Korean Education and Employment Panel). A Data mining decision tree model revealed that: (1) Suicide ideation was a risk factor for running away among smokers. (2) High self-evaluation was a risk factor for running away among individuals that smoked and had no suicide ideation. (3) Drinking was predicted as a risk factor for no smokers, while family life dissatisfaction was predicted as a risk factor among non-smokers that drank. (4) Negative relationship with mother was predicted as a risk factor among non-drinking non-smoking.

This study examines the extent to which mediator variables, including hostility, paranoid, and attitude toward wife abuse, help explain the relationship between exposure to violence in family of origin while growing up and subsequent abuse against wives. SPSS 10.0 for windows is used to examine data obtained through 223 married men who live in Kwanju. The findings indicates that (a) exposure to violence in family of origin while growing up is related to all mediator variables; (b) exposure to violence in family of origin while growing up and mediator variables are associated with abuse against wife; (c) experiencing of child abuse predict perpetration of sexual abuse against wife, and witnessing of father-to-mother abuse account for more strongly perpetration of psychological and physical abuse against wife: (d) in general, exposure to violence in family of origin has more strong indirect impact on wife abuse for adult male.

Three groups of maltreated Korean children (Grades 1 through 3) drawn from Child Protective Services (CPS) agencies were compared to a control group of nonmaltreated children on academic achievement as measured by standardized tests of reading, spelling, arithmetic, and writing. Findings were that maltreated children performed significantly below their nonmaltreated children on the standardized tests, in particular in arithmetic. In first grade, maltreated children did not perform below nonmaltreated children on writing and reading, but maltreated children gradually declined in academic performance in these skills. The older, grade 3, children showed more serious academic problems than the younger children (Grades 1 and 2) on four academic skills. This suggests that early experience of child abuse have a strong affect on children's academic achievement.

This study aim to identifying important determinants of happiness from university students' view point. To identify the determinants of happiness, focus group interviews were conducted. After carrying content analysis, five main categories were identified: 'Enjoying the present(enjoy the hobby, group activities and trivial things)', 'Self-regulation not dictated by anyone', 'Pursuing self-generated personal goals(goal-oriented, process-oriented)', 'Enjoying hassle-free moment(physical comport, psychological comforts being alone), 'Forming a good relationships (wide range of relationships, quality of relationships). This result is expected to provide deep understanding of students' happiness in planning programs and policies.
