Purpose: The research aimed to investigate the factors affecting cancer preventive behavior among patients with early gastric cancer (EGC) who underwent endoscopic submucosal dissection (ESD). Methods: Data were collected from 126 patients who underwent ESD for EGC and who were recruited from a single university affiliated hospital, Seoul, Korea. The data were analyzed by descriptive statistics, independent t-test, one-way ANOVA, Pearson’s correlation coefficient, and multiple regression analysis. Results: The average score of cancer preventive behavior was 66.87±10.36 out of 90. Correlations between attitude toward cancer and preventive behavior regarding cancer were positive (r=.26, p=.004). Also, the regression analyses revealed that factors affecting cancer preventive behavior included perception of cancer screening, attitude toward cancer, and age. A history of drinking alcohol on the other hand was negatively related to cancer preventive behavior. The regression analyses explained 31% of variance (F=6.50, p=.037). Conclusion These results suggest that nurses should develop a program for risk groups (people who drink alcohol regularly, are under the age of 65 and who have poor self-health care after ESD). And such a program should include interventions to improve attitudes toward cancer and perception of cancer screening, and encourage physical activity.

A 43-year-old female was admitted for a laparoscopic surgical procedure. Her past history included two uneventful general anesthesias, but anaphylactic shock due to an unknown drug occurred during her third surgery. Induction was performed with thiopental sodium, but an immediate anaphylactic reaction developed with cardiovascular collapse. We resuscitated the patient and she recovered without any complication.

Background and Objectives: This study aimed to investigate the occupational performance of Korean workers with and without hearing loss and analyze the hearing-related difficulties in the working environment. Subjects and Methods: The Amsterdam checklist for hearing and work was used for the analyses and the occupational environments of the Korean workers were investigated. Out of 129 total participants, 86 workers experienced severe to profound hearing loss and 43 had the normal hearing ability. The hearing-impaired workers were recruited from two leading vocational centers and normal-hearing workers were their colleagues. Results: The hearing-impaired workers were found to take fewer sick leaves and exhibited higher rates of permanent job statuses compared to the normal-hearing workers. Workers with hearing loss rarely detected background sound; however, they could perceive reverberation more frequently. They felt more satisfied with their careers than the normal hearing workers as they received social support and needed to put their effort into hearing for most hearing activities. Furthermore, the effort in hearing increased with the increase in job demand, job control, social support, and career satisfaction. The working hours per week increased with the increase in age, education level, job demand, job control, and social support. Different trends were observed in 9 out of 12 variables while comparing the data from the present study with that obtained from the hearing-impaired workers of the Netherlands, indicating a large difference between countries. Conclusions Although the hearing-impaired Korean workers operate diligently with good job positions, it is necessary to enhance their acoustic environment and provide them social support. Considering the cultural background of the hearing-impaired workers, the development of suitable vocational rehabilitation programs and specific questionnaires is strongly recommended worldwide.

Central serous chorioretinopathy may induce poor eyesight and serous retinal detachment. However, its exact cause has not been well established thus far. It can be associated with systemic high-dose corticosteroid treatment mainly for young and middle-aged men and may spontaneously regress or recur after withdrawal from corticosteroid. After corticosteroid administration for Behcet's disease, it is necessary to identify any ocular symptoms. Behcet's disease can lead to the development of ocular complications, such as uveitis, hypopyon, retinal vasculitis, optic neuritis, angiogenesis, secondary cataract, and glaucoma. It is possible to diagnose any of these complications via optical coherence tomography and digital indocyanine green angiography. It is easy to neglect an ocular symptom that may appear after a low-dose corticosteroid treatment as an ocular complication in patients with Behcet's disease. Thus, we report on a case concerning high-dose corticosteroid treatment with a literature review.

With a high sound quality stimulated by the electrical device and a large inclusion in medical insurance, the number of cochlear implant recipients has been rapidly increased in Korea. Today, it is not surprising that early implanted young children with congenital deafness show a similar performance to their normal hearing peers in speech perception. However, the cochlear implant users still have a trouble to enjoy music. This review study aims to introduce briefly about acoustic components that required to perceive the music and understand a relationship between cochlear implantation and temporal fine structure. For the pediatric implant users who have less experience on acoustical sound features but are much familiar with the electrically stimulated sound, perceiving the music seems to be challengeable due to the lack of temporal fine resolution related to pitch and timbre among various components of music. Four representative test batteries for evaluating the recipients' ability of the music perception were mentioned and effective auditory music trainings were discussed with analysis of related investigations. Unlike hearing aids users who usually depend on fitting algorism for better music quality, the cochlear implant users need systematic training to improve their music perception ability. In conclusion, advancement of speech processing technology which can provide accurate information about the temporal fine structure of incoming music to the recipients needs to be developed. Also, a practical application of music training should be recommended as a part of auditory training for the cochlear implant users.

Background and Objectives: Natural and synthetic speech signals effectively stimulate cortical auditory evoked potential (CAEP). This study aimed to select the speech materials for CAEP and identify CAEP waveforms according to gender of speaker (GS) and gender of listener (GL). Subjects and Methods: Two experiments including a comparison of natural and synthetic stimuli and CAEP measurement were performed of 21 young announcers and 40 young adults. Plosive /g/ and /b/ and aspirated plosive /k/ and /p/ were combined to /a/. Six bisyllables–/ga/-/ka/, /ga/-/ba/, /ga/-/pa/, /ka/-/ba/, /ka/-/pa/, and /ba/-/pa/–were formulated as tentative forwarding and backwarding orders. In the natural and synthetic stimulation mode (SM) according to GS, /ka/ and /pa/ were selected through the first experiment used for CAEP measurement. Results: The correction rate differences were largest (74%) at /ka/-/ pa/ and /pa/-/ka/; thus, they were selected as stimulation materals for CAEP measurement. The SM showed shorter latency with P2 and N1-P2 with natural stimulation and N2 with synthetic stimulation. The P2 amplitude was larger with natural stimulation. The SD showed significantly larger amplitude for P2 and N1-P2 with /pa/. The GS showed shorter latency for P2, N2, and N1-P2 and larger amplitude for N2 with female speakers. The GL showed shorter latency for N2 and N1-P2 and larger amplitude for N2 with female listeners. Conclusions Although several variables showed significance for N2, P2, and N1-P2, P1 and N1 did not show any significance for any variables. N2 and P2 of CAEP seemed affected by endogenous factors.

Purpose: The purpose of this study is to clearly classify the roles of Physician assistants and to identify obstacle factors and necessary factors for the operation of the system when they are performing the roles of Physician assistants. Methods: This is a descriptive research study to analyze the roles of Physician assistants and to understand the expected roles of Physician assistants according to each medical personnel (doctor, nurse, Physician assistants). Results: The obstacles to work are the lack of legal protection, and unclear work guidelines, and the matter necessary for the operation of the system is the legal protection. There were statistically significant differences in health collection ability, physical examination, drug response monitoring, and reporting in terms of the differences in role expectations considered by medical professionals regarding the roles of Physician assistants. Conclusion Physician assistants need to develop various educational programs and materials, cultivate the ability to perform Physician assistants, and develop an advisory role through effective problem-solving between departments and increase the quality and satisfaction of Nursing care.

Since noise-induced hearing loss (NIHL) is one of prevalent issues in the occupational settings, hearing protection device (HPD) has been widely used to reduce noise exposure levels and to prevent developing NIHL. This review study aimed to introduce several types of the HPD in terms of current trends, its variety and functions, and application. Including a brief history of the HPD, we explain its two types, i.e., passive and active functions, in the first part of main body. The passive HPD has a flat attenuation across the overall frequency range, whereas the active HPD effectively preserves communication components such as meaningful speech with low intensity stimuli while filtering out the high levels of noise. In the second part of the main body, we discuss some negative issues of hearing functions when users are wearing the HPD. In detail, the active HPD does not much degrade the hearing performance for speech detection/recognition and sound source localization compared to the passive HPD. Rather, reduced sound (or music) quality is improved with active one in general. In the final part, we mention that although various applications in the special fields such as factory, mining, army, airplane, and music have been demonstrated, the usage and awareness of HPD in occupational aspect may not follow its fast technological development. Furthermore, most people do not know about either importance or use method of HPD in the non-occupational setting. For these reasons, we conclude that hearing professionals have to access the latest trends of the HPD and to increase their knowledge on it, and thus they should provide the best HPD prescription for the public as well as employees who have to protect their ears from hazard noise impacts.
