Hairy tongue is a disease caused by hypertrophy of filiform papillae on the tongue dorsum. Clinically, it occurs on the posterior 1/3 of the tongue dorsum and is rarely observed on the lateral and tip of the tongue. Several types of colored pigmentation from white to brown and black appear depending on the ingested food and the existing pigmentation inducing bacteria. Although clinically asymptomatic, patients will visit the clinic for esthetic problems and at rare intervals experience nausea, halitosis, dysgeusia and unpleasant sensation. The exact etiology is yet not known but causes such as inappropriate oral hygiene control, a shift in oral bacterium, infection, radiotherapy, use of antibacterial drugs or immunosuppressants, excessive smoking or alcohol drinking and decrease of salivary flow rate may be a factor of the disease. Clinical symptoms are quite typical and diagnosis may be made simply by observation, not necessarily biopsy. Treatment of hairy tongue is done by eliminating the etiology factors, brushing the tongue gently with a tongue cleaner and in some cases using keratolytic agent. Although it is rare to treat hairy tongue surgically, we will introduce a case successfully treated using carbondioxide laser($CO_2$ laser), after no sufficient improvement had been made by conservative treatment.

Extracorporeal Shock Wave Therapy (ESWT) is an innovative treatment in chronic musculoskeletal pain management and cardiovascular diseases. In this study, we surveyed the acoustic shock wave outputs from the domestically used focal type ESWT devices. The survey data were collected through 30 technical documents registered to the Ministry of Food and Drug Safety (MFDS), Rep. Korea. The results show that the focusing geometry varies largely, 5 mm to 65 mm in the focal length, 3 mm to 30 mm in focal width, and 4 mm to 108 mm in focal depth. The maximum positive pressure (P+) ranges from 7 MPa to 280 MPa, the focal Energy Flux Density (EFD) from 0.0035 mJ/㎟ to 35 mJ/㎟, and the energy per pulse (E) from 0.737 mJ to 80.86 mJ. All domestic PE-type (five) and one EM-type domestic devices included in the analysis of the correlation between P+ and EFD are shown to be far beyond the usual ranges and do not comply with expected correlation so that the reliability of their data was suspected. For the suspected, post-performance tests are required by a recognized testing agency. MFDS guidelines need to be revised so that the pass criteria for the shock wave acoustic outputs can be based on the clinical tests for indications.

The purpose of this study was to investigate the effects of nurses' perceived burden from work and health problems on the presentism of nurses. The study subjects were recruited from four general and tertiary hospitals in K province and D metropolitan city. A quarter of nurses had shoulder, back, and neck pain and average number of health problems was 3.62. The nurses' presenteeism score was $43.37{\pm}12.43$ points out of 100 points. There was a statistically significant relationship between nurses' perceived burden, numbers of health problems, and presenteeism. The numbers of health problems and perceived burden of nurses had significant effects on presenteeism of nurses while controlling demographic factors such as length of work experience, job position, types of hospital, and gender. These results suggested that the less burden from work and the lower number health problems could result in the lower level of presenteeism of nurses. Therefore, it is necessary to develop diverse strategies to reduce the burden of nurses and health problems at both individual and organizational levels as a way to increase productivity of hospital.

Methods: Response to questionnaires from 89 participants were evaluated using SAS and CHISQ analysis. The questionnaires included the following items: 1) the characteristics of participants; 2) the characteristics of patients; 3) the difficulties of patient care; 4) the satisfaction with the program Results: The participants consist of 33 patients (37.5%) and 56 family members (56.2%). Diagnosis included mainly stomach, lung, breast, and colon cancer. Participants of family members consisted of spouse, parent, children, daughter-in-law, and siblings (in decreasing order). The participants were interested in the medical information, nutrition, pain and symptom management, and psychosocial adaptation. They had difficulties in emotional problem, nutrition and symptom management. Even though it was a single session of group education, the level of satisfaction was high (95%). Conclusion: This research shows that even the single session of the group education for the advanced and terminal cancer patients and their family members is very helpful by giving them the necessary information. In order to develop comprehensive care-giving services, more specific informations, more opportunities to participate in such sessions and longer question-answer time is required.

Cannabis sativa L. belongs to the Cannabaceae family and is an annual herbaceous flowing plant. The plants can be classified into narcotic marijuana and nonnarcotic hemp. Different parts of C. sativa L. have been used as food, medicine, cosmetics, fiber and textile. However, the use of leaf, flower, and seed of C. sativa L was forbidden in Korea in January 1977 as a result of the Cannabis Control Act due to the narcotic properties. The plant's mature stems have limited uses for the production of fiber and sheets. Recently, various cannabinoids, terpenes and essential fatty acids were identified from C. sativa L., and their safety and useful bio-activities, such as neuroprotective, anti-inflammation, antithrombosis, antiepileptic, and antimicrobial activities, and the relief of pain, have been highlighted. Furthermore, the process of reduction of tetrahydrocannabinol, a representative narcotic compound, and the isolation of cannabidiol, a nonnarcotic active compound in C. sativa L., have been determined. These findings resulted in the legalization of C. sativa L. in Korea for medical use in December 2018 and the exclusion of C. sativa L. from the narcotic list of the UN Commission on Narcotics Drugs (UNCND) in December 2020. Therefore, developments of various high-value added products have commenced worldwide. Additionally, in 2021, the Korean government deregulated special zones based on hemp. In this study, the current status and the prospect of the hemp industry, as well as essential techniques for developing new hemp products, are provided for the activation of the Korea Green-Rush.

The current study examined the mediating effect of self-efficacy (SE) in the relationship between work ability (WA) and work satisfaction (WS) perceived by reemployed workers who have experienced industrial accidents based on social cognitive career theory (SCCT), and investigated the effect of Industrial accident sequelae and workplace relationships (WR) on these variables. The data of 976 newly employed workers were selected from the data of the Panel Study of Worker's Compensation Insurance collected in 2018. The data were analyzed by Structural Equation Modeling through SPSS and AMOS programs. It was found that WA had a positive effect on WS through SE. In addition, it was found that the level of pain, the severity of the disability, and the activities of daily living had a negative effect on WS through WA and SE sequentially. Meanwhile, it was found that the WR was affected by the activities of daily living, and had a positive effect on WS through WE. These results emphasize that it is important to provide support to manage sequelae and increase SE in order to help victims of industrial accidents return to the job market and live satisfactorily. It also suggests that SCCT is useful in explaining WS of industrially injured workers.
