A cultural exchange program widens the horizons of students. It gives them the opportunity to associate with other societies and learn their cultures at the same time. This program also serves as a training ground where students enhance their skills, acquire learnings, and gain experiences that will help them in their future careers and make them more competitive than others. Hence, the objective of this study is to come up with an output from a set of guidelines established and gathered from the different "work and travel" experiences of the participants. This study adopted the phenomenological and was conducted in places that are relatively quiet for recording, and suitable and convenient for both the researchers and participants. The researchers gathered data through in-depth interviews of samples gathered through snowball sampling. Cellphones were used to record interviews. At the end of the thematic analysis of information, the researchers came up with three major categories which included: (1) 'having the opportunity to know the industry well and improve one's capability', 'undergoing different cultural exchange experiences for better development', and 'being able to practice intercultural immersion'. Some of the researchers' recommendations would be to institute a feedback mechanism such as personal interviews, monitoring visits, etc. and use the output, a set of guidelines, that would help the future 'work and travel' participants to prepare and anticipate the program they would undergo.

In Korea, the school foodservice program has been expanding rapidly in recent years, partly as a result of increased government support. With the growth in the number of schools offering foodservice programs, food safety and sanitation concerns have been increasing. To assist with program improvement, a situation analysis was carried out, with the focus on equipment and sanitary management of school foodservice programs under flour different management systems. A questionnaire was mailed to the foodservice directors of 234 randomly selected schools chi[h included elementary, middle and high schools at the national level. Among them, one hundred and sixty-five responses reasonably completed were used for the analysis. This study classified each school's foodservice management into one of four types : independent-conventional, independent-commissary, contract-conventional, and contract-delivery. The results show that the monitoring of employees' health and personal hygiene, and employees' sanitary education was well conducted, but that the sanitary education of the voluntary parent workers was largely ignored. Eighty-six percent of the schools had their drinking water tested for sanitation, and the results showed that more effort is needed in careful management of drinking water in order to prevent foodborne illnesses and bacillary dysentery. In general, contract management showed lower scores in foodservice equipment and their efficiency, compared with independent management. A relatively high number of schools on the contract-delivery management system employed nurses and leachers instead of dietitians and foodservice directors. The adoption of the HACCP (Hazard Analysis Critical Control Point) system was lowest in contract-conventional and contract-delivery management systems, and highest in elementary schools using the independent-conventional system.

e-Learning contents are composed of compounding multimedia data. It requires many professionals in contents development stage. The process of e-learning contents development can be seen as a collaborative work. In the perspective of a collaborative work process, the whole process of e-learning contents development would be regarded as collaborative work process for each participant as well as for whole group members. Most of collaborative works in contents development field are widely distributed. Members of work groups require workspaces for sharing information and communicating each other. In addition to workspaces, it also needs to support collaborative reflection such as planning for collaborative work and monitoring for work process. This paper is intended to develop the reflective collaborative work system for e-Learning contents development in order to support the systemic process of e-learning contents development. The reflective collaborative work system is composed of four supportive parts: work flow management, personal workspace, collaborative workspace, and collaborative reflection.

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood. This disorder, in addition to its main symptoms, creates significant difficulties in education, social performance, and personal relationships. Given the importance of rehabilitation for these patients to combat the above issues, the use of virtual reality (VR) technology is helpful. The aim of this study was to highlight the opportunities for VR in the rehabilitation of children with ADHD. This narrative review was conducted by searching for articles in scientific databases and e-Journals, using keywords including VR, children, and ADHD. Various studies have shown that VR capabilities in the rehabilitation of children with ADHD include providing flexibility in accordance with the patients' requirements; removing distractions and creating an effective and safe environment away from real-life dangers; saving time and money; increasing patients' incentives based on their interests; providing suitable tools to perform different behavioral tests and increase ecological validity; facilitating better understanding of individuals' cognitive deficits and improving them; helping therapists with accurate diagnosis, assessment, and rehabilitation; and improving working memory, executive function, and cognitive processes such as attention in these children. Rehabilitation of children with ADHD is based on behavior and physical patterns and is thus suitable for VR interventions. This technology, by simulating and providing a virtual environment for diagnosis, training, monitoring, assessment and treatment, is effective in providing optimal rehabilitation of children with ADHD.

In the present study, we developed a nuclear stethoscope interfaced with a personal computer (APPLE- II) and evaluated it's performances as compared with the gamma camera. This single-probe, ECG-gated system has been used for displaying the left ventricular time-activity curves, the peak ejection time and its rate, the peak filling time and its rate, and the R-R interval distribution. The radioactivity was measured at every 10msec around the ventricular region, where the activity curves shows the maximal peak to peak variations. The background activity was measured around the lung area showing its counts approximately 50% of the end-diastolic count with minimal variations. The average time-activity curves of 100 beats were used for analysis in the equilibrium study after intravenous injection of 15-20mCi of Tc. The ejection fractions measured by the nuclear stethoscope(Y) were compared with those measured by gamma camera(X) in 47 patients with various heart diseases. The correlation coefficient between two measurements was 0.766 with a relation of Y=1.04 x-8.48. Also, the high reproducibility was obtained for the same patient. Also, the high reproducibility was obtained for the same patient. From this study, we conclude that this device is useful for continuous monitoring in the intensive care unit, as it is portable, compact, and inexpensive.

Objectives: The aim of this case study is to verify the chemical exposure reductions for various chemicals by substituting the ingredients of raw materials in a polyurethane(PU) foaming industry. The PU foaming process was making various passenger car seats from chemicals such as toluene diisocinate(TDI), methylene bisphenyl isocyanate(MDI) and polyols. Methods: Basic process data and workers' health effects could be gathered by interviewing managers and reviewing previous exposure monitoring data. Amine, aldehyde and isocyanate chemicals were analyzed following the NIOSH-NMAM. Area sampling methods rather than personal sampling were introduced for this field investigation. Results: Two amines, triethylene diamine(TEDA) and N,N,N',N'-Tetramethyl-1,6- hexanediamine(TMHDA) were identified in raw polyol, cured PU foam and air. The average concentrations of TEDA and TMHDA showd less than 1 ppm by area sampling; however, that caused halovision among workers in PU-PAD process. Aldehydes and isocyanates were detected in the air while the concentrations were relatively low compare to occupational exposure limits. Successful raw material substitution from nonreactive amine to reactive amine could reduces air-borne amine and aldehyde levels by about 70%. Halovision had been disappeared successfully in the process. Conclusions: Several amines caused halovision among workers in PU-PAD process, especially during summer season in spite of relatively low levels. Combination of reactive amines into urethane foam could reduced vapor generation into air, which resulted in the elimination of eye troubles in the process.

Objectives: Acute methanol poisonings known to be typical occupational diseases occurring in developing countries broke out in sub-contract manufacturers in the early 2016. The present paper attempted to identify underlying causes which hide under apparent findings, and suggest alternative policies to prevent recurrence of similar intoxication Methods: We evaluated occupational health and safety characteristics of workers in micro-enterprises similar to workplaces with methanol poisoning by in depth-interview of employers, workers, and labor inspectors, and literature review. Results: The common findings of workplaces with methanol poisoning were addressed; First, the victims were illegal agency workers. Second, the workplaces were sub-contract micro-manufacturers with less than 5 employees. Investigators found that local ventilations did not work, while most of workers did not wear any proper personal respiratory protective equipment in the workplace. In addition, periodic environmental monitoring and medical check-ups were not done. However, these apparent findings do not appear to be root causes of methanol poisoning. Our in depth-analysis clarified a root cause; micro-enterprises with less than 5 employees are exempted with essential regulations of OSH Act, and employers do not know about OSH Act. Conclusions: We suggest occupational health policies to prevent recurrence of similar intoxication; First, government should introduce programs so that all employers should know about employers' responsibilities in OSH Act from the start of business. Second, even manufacturers with less than 5 employees should not be exempted with essential regulations of OSH Act. Finally, employers should take responsibilities for health and safety of all the workers including agency workers working in workplaces.

Objectives: The nutritional status of cancer patients undergoing chemotherapy is closely related to the compliance of nutrition education. However, as chemotherapy is conducted repeatedly, compliance with nutrition management is lowered, leading to malnutrition. Malnutrition is related directly to the quality of life after surgery in cancer patients. Therefore, this study examined the factors related to compliance with nutrition management during chemotherapy. Methods: In this study, five subjects with colorectal cancer undergoing adjuvant chemotherapy were interviewed in-depth using the Giorgi study method. The contents of the nutrition education visits and in-depth interviews were transcribed in the language of the subject after recording, and the appropriateness of the data was improved by reflecting the subject's actions and facial expressions. Results: After conducting the in-depth interviews for each subject, the experience of the subject's diet and adjuvant chemotherapy was drawn into two domains, six elements, and 26 sub-elements. In the cognitive domain, the patients experienced physical and psychological changes, and the need for nutrition management was recognized by analyzing the dietary causes of the diseases. In the domain of practice, a knowing-doing gap was formed, unlike the patient's will. Factors that inhibited compliance with nutritional management included digestive problems, sensory changes, loss of appetite, and social interaction stress. Conclusions: Dietary management is very important for patients receiving periodic anticancer therapy, and step-by-step training and personal monitoring based on the chemotherapy order is necessary to maintain the patient's will and social and environmental support.

This article presents strengths of Computer-Assisted Personal Interviewing(CAPI) in social surveys with complicated questionnaires, from examples of a pilot and the first year surveys of the Korean Longitudinal Study of Ageing(KLoSA). This study focuses on how to improve the quality of data by using CAPI and finds five strengths among others. First of all, CAPI can contribute to reducing response errors by structuring the logic and path of questionnaires, setting a response range, and maintaining response consistency. Second, CAPI enhances convenience of interviewing by allowing customized questions and automatic calculation and scoring. It also allows the 'help' function. Third, its random arrangement of questions prevents response order effect and/or questions order effect. Fourth, CAPI can raise the response rate by reducing item non-responses. Fifth, it makes it easy monitoring interviewing, thus helps supervising interviewers and modifying questionnaires when necessary. These merits of CAPI contribute to reducing possible errors in the process of interviewing, therefore improve the data quality.
