This research investigates how a Virtual Reality (VR)-based simulation could be used to train safe operation skills for forklift operators. Forklift operation is categorized as high-risk work by many occupational health and safety regulators and authorities due to high injury and fatality rates involved with forklifts. Therefore, many safety guidelines have been developed for forklift operators. Typically, forklift operation safety training is delivered based on instructional texts or videos, which have limitations in influencing people's safety behavior. Against this background, we propose a VR-based forklift simulator that can enable safe operation skills training through a feedback system. The training program consists of several modules to teach how to perform the basic tasks of forklift operation, such as driving, loading and unloading, following the safety guidelines. The system provides instantaneous instructions and feedback regarding safe operation. This training system is based on the model of "learning-by-doing". The user can repeat the training modules as many times as necessary before being able to perform the given task without violating any safety guidelines. The last training module tests the user's acquisition of all safety skills required. The user feedback from several demonstration sessions showed the potential usefulness of the proposed training system.

Purpose: This study investigated the effects of 1 year of training on imaging diagnosis, using static ultrasonography (US) salivary gland images of Sjögren syndrome patients. Materials and Methods: This study involved 3 inexperienced radiologists with different levels of experience, who received training 1 or 2 days a week under the supervision of experienced radiologists. The training program included collecting patient histories and performing physical and imaging examinations for various maxillofacial diseases. The 3 radiologists (observers A, B, and C) evaluated 400 static US images of salivary glands twice at a 1-year interval. To compare their performance, 2 experienced radiologists evaluated the same images. Diagnostic performance was compared between the 2 evaluations using the area under the receiver operating characteristic curve (AUC). Results: Observer A, who was participating in the training program for the second year, exhibited no significant difference in AUC between the first and second evaluations, with results consistently comparable to those of experienced radiologists. After 1 year of training, observer B showed significantly higher AUCs than before training. The diagnostic performance of observer B reached the level of experienced radiologists for parotid gland assessment, but differed for submandibular gland assessment. For observer C, who did not complete the training, there was no significant difference in the AUC between the first and second evaluations, both of which showed significant differences from those of the experienced radiologists. Conclusion: These preliminary results suggest that the training program effectively helped inexperienced radiologists reach the level of experienced radiologists for US examinations.

Irradiation-induced defects and the precipitates in the wrapper material of the Indian Fast Breeder Test Reactor (FBTR), SS 316 are analyzed using the synchrotron source-based Angle Dispersive X-Ray Diffraction (ADXRD) technique with X-rays of energy 17.185 keV (wavelength ~0.72146 Å). The differences and similarities in the high displacement damage samples as a function of dpa (displacement per atom) and dpa rate in the range of 2.9 × 10^-7- 9 × 10^-7 dpa/s are studied. Ferrite and M₂₃C₆ are commonly observed in the present set of high displacement damage 40-74 dpa SS 316 samples irradiated at temperatures in the range of 400-483 ℃. Also, the dislocation density has increased as a function of the irradiation dose. The X-ray diffraction peak profile parameters quantified such as peak shift and asymmetry show that the irradiation-induced defects are sensitive to the dpa rate-irradiation temperature combinations. The increase in yield strength as a function of displacement damage is also correlated to the dislocation density.

이 연구에서는 산학일체형 도제학교의 학교 및 기업 관계자들이 독일 스위스의 도제교육 사례를 탐색할 수 있는 기관을 방문한 후, 참여자의 만족도와 인식도 변화를 분석하고자 한다. 이를 바탕으로 도제학교에 대한 이해를 제고하고 내실 있는 연수 실시를 위한 개선 방안을 마련하고자 한다. 본 연구를 통해 국외연수에 참가한 학교 관계자와 기업관계자의 국외연수 프로그램 내용과 도제교육 운영에의 도움 등 만족도는 매우 높은 것을 확인할 수 있다. 다만 도제교육 관련 기관 유형별(직업학교, 기업, 상공회의소, 수공업협회, 연구기관) 만족도 간에는 참여자의 연령별로는 차이가 없었으나 근무지역, 직위 등에 따라 만족도 간에 통계적으로 유의한 차이가 있는 것으로 나타나 분석 결과를 바탕으로 향후 방문 기관 선정 등에 반영할 필요가 있다. 학교 및 기업 관계자의 국외연수 참여에 따른 산학일체형 도제학교 운영에 대한 인식도 변화와 관련하여 학교 관계자의 경우는 연수 전보다 연수 후에 도제교육 이해, 계획, 실행, 평가 전 영역에 걸쳐 인식도가 높아졌으나 기업 관계자의 경우는 그렇지 않은 것으로 나타났다. 그러나 기업관계자도 국외연수가 도제교육을 운영에 대해서는 매우 도움이 된다고 이해하고 있으므로 향후 국외연수의 효과를 보다 높이기 위해서는 사전 연수 또는 정례협의회, 사업단별 협의회 등을 통해 도제교육에 대한 이해를 도울 수 있는 많은 정보를 제공할 필요가 있다. 그리고 우리나라와 독일, 스위스, 호주의 도제교육 실행을 위한 사회 문화적 여건의 차이가 매우 크므로 단순한 비교 분석보다는 우리나라 시스템 내에서 개선 방안을 도출할 수 있는 방향에서의 국외연수 운영이 필요하다.

The purpose of this study is to understand how to activate field training internships through former researches related to training internships. The concept of field training is the same as education of work experience. Students have experienced the skills of practical jobs in the tourism industry and could enhance acquisition of professional theories. According to domestic former researches, students who participated in hotel field practice hardly satisfied with internships due to unreasonable duties, burdens and circumstances regardless of efficiency of school curriculum. Also, they showed dissatisfaction with compensation. However, foreign studies have only focused on communication between hotels and schools. Finally, in order to activate industrial field training internships, schools and hotels have more delicate harmonization to address training internship problems. In addition, promoting field training internships must include proper incentives and must be supported by school. And also the hotel management must offer incentives to the students who are under field training internships in the hotel. From internship programs, students could get much more benefits in hotel job application.

Background As the demand for cosmetic surgery continues to rise, plastic surgery programs and the training core curriculum have evolved to reflect these changes. This study aims to evaluate the perceived quality of current cosmetic surgery training in terms of case exposure and educational methods. Methods A 16-question survey was sent to graduates who completed their training at a U.S. plastic surgery training program in 2017. The survey assessed graduates' exposure to cosmetic surgery, teaching modalities employed and their overall perceived competence. Case complexity was characterized by the minimum number of cases needed by the graduate to feel confident in performing the procedure. Results There was a 25% response rate. The majority of respondents were residents (83%, n=92) and the remaining were fellows (17%, n=18). Almost three quarters of respondents were satisfied with their cosmetic training. Respondents rated virtual training as the most effective learning modality and observing attendings' patients/cases as least effective. Perceived competence was more closely aligned with core curriculum status than case complexity, i.e. graduates feel more prepared for core cosmetic procedures despite being more technically difficult than non-core procedures. Conclusions Despite the variability in cosmetic exposure during training, most plastic surgery graduates are satisfied with their aesthetic training. Incorporation of teaching modalities, such as virtual training, can increase case exposure and allow trainees more autonomy. The recommended core curriculum is adequately training plastic surgery graduates for common procedures and more specialized procedures should be consigned to aesthetic fellowship training.

Background: Although nuclear disaster is considered rare, its effects are serious, and we must prepare a system to enable an effective response. Materials and Methods: Since 2010, we have been offering a two-day seminar to provide current nurses and radiological technologists with basic knowledge and train them in radiation emergency medicine (REM) techniques. This training offers lectures to deepen each specialty from the perspective of REM, as well as exercises on ways to handle irradiated and/or contaminated patients. Participants were expected to treat patients according to the concept of REM. Results and Discussion: All participants learn to assess and decontaminate contaminated wounds through drills. The questionnaire survey for participants indicated that participants were satisfied with this training and wanted to attend again. Conclusion: We believe that this training course will provide a valuable opportunity for medical professionals to gain knowledge and expertise in REM.

The effects of Physical exercise, gymnastics and sports on the cardiopulmonary function were studied in the middle and high school toys. The subjects were divided into 4 groups; non-training group and training group in both middle school and high school boys. In the above groups, pulmonary function studies were performed, and blood pressure and the heart rate were also checked to evaluate physical fitness during and immediately after running exercise on the tread-mill, with the speed of 5 MPH and elevation of 9% and 11.25%. The types of sports in the training group were base ball, body building, Taekwondo (Korean style boxing) and hand ball. The results obtained were as followings: 1) In the training group, cardiopulmonary function showed some tendency of the increase comparing to the non-training group. 2) The increase in cardiopulmonary function was observed according to the age became older, but the clear changes on cardiopulmonary function was not observed as the difference of the group between the training and the non-training. 3) The expiratory volume was decreased as the increase of age except 17 years of age for the value of the per kg body weight. 4) In the non-training group, the mean value of oxygen consumption under maximum work load was increased, while those in the training group was decreased. But it may be noted that oxygen consumption for the expiratory volume was increased in the training group, and that the oxygen cost in the training group was .higher than that of the non-training group. 5) The pulse pressure of the high school group during and immediately after running exercise was observed in the higher value comparing with that of the middle school group It was suggested that the changes of the pulse pressure was owing to the method of determination and that to the decrease of diastolic pressure caused by the decrease of peripheral vascular resistance up to critical closing pressure. 6) Any differences of the changes in the heart rate between the training group and non-training group was not observed during and immediately after running exercise. 7) The relative value of the expiratory volume to the heart rate was decreased in the elder age group.
