Probiotics are live microorganisms that confer health benefits to the host when administered in adequate amounts. Although recommendations for probiotic use should be strain-specific, many systematic reviews, including recommendations from different societies, recommend probiotic use in general, providing no relevant information for healthcare professionals regarding which probiotic to recommend for which clinical indication, at what dose, and for how long. This narrative review aimed to present the available evidence on the use of probiotics in the prevention and treatment of common gastrointestinal diseases in children, considering the strain and dose used. Furthermore, this study summarizes the evidence on the possible side effects and quality of products containing probiotics.

This study examines secondary school science teachers' use of science museums in their teaching and their perception/evaluation/utilization of the educational programs in Korean science museums. We found that teachers do not use science museums in close connection with their formal education; therefore, the students' experiences usually are minimal or are personal experiences. The main reason for this infrequent use of science museums is not because of their insignificant educational effects, but because of the lack of external and administrative support systems. Science teachers want the museums to have structured/organized programs such as science camps or experiments and a lending program which would provide experimental equipment and exhibits relevant to the school science curriculum. 90% of teachers who answered the survey wanted to participate in developing and managing the educational programs of science museums. The educational programs would be used more effectively in relation to formal science learning if the science teachers, who are science education professionals, participated in managing and planning the educational programs of science museums.

Availability, awareness and use of electronic resources provide access to authoritative, reliable, accurate and timely access to information. The use of electronic information resources (EIRs) can enable innovation in teaching and increase timeliness in research of postgraduate students which will eventual result into encouragement of the expected research-led enquiry in this digital age. The study adopted a descriptive survey design. Samples of 300 of postgraduate students within seven out 13 Faculties were randomly selected. Data were collected using questionnaire designed to elicit response from respondents and data were analyzed using descriptive statistics methods percentages, mean, and standard deviation. Results indicated that internet was ranked most available and used in the university. Low level of usage of electronic resources, in particular, full texts data bases is linked to a number of constraints: Interrupted power supply was ranked highest among other factors as speed and capacity of computers, retrieval of records with high recall and low precision, retrieving records relevant to information need, lack of knowledge of search techniques to retrieve information effectively, non possession of requisite IT skills and problems accessing the internet. The study recommended that usage of electronic resources be made compulsory, intensifying awareness campaigns concerning the availability, training on use of electronic resources and the problem of power outage be addressed.

This study aims to analyze how specific features of a mobile platform such as economic feasibility, interactivity, safety, and design are correlated with perceived ease of use and customer satisfaction, targeting those who purchase delivery food on a mobile platform dedicated to delivery services. A survey was conducted on customers who had bought delivery food on a mobile platform and the data collection was conducted from August 19, 2019 to September 18, 2019, using 300 mobile platform service users. A total of 300 copies were retrieved. 249 valid samples of 300 copies were analyzed with SPSS 23.0 and AMOS 23, and In addition, programs including SPSS and AMOS were used for the analysis of frequency, confirmatory factor, reliability and validity, correlation and structural equation model. Major findings of such analysis are as follows. First, design characteristic of a mobil platform had relevant impacts on perceived ease of use. However, economic feasibility, interactivity, and safety did not significantly affect perceived ease of use. Second, perceived ease of use had a significantly influenced on the extent of customer satisfaction. Hence, from practical and academical point of views based on the results of this analysis, this study is expected to provide directions and some practical and useful implications for a mobile platform for food delivery services.

Purpose: This study was conducted to review physiological mechanisms of internet addiction and to construct a theoretical framework for cognitive behavioral therapy for internet addicts. Methods: We searched for relevant literature in the PubMed and RISS databases using the terms "internet addiction", "internet game addiction", "internet abuser", and "online game". Only English, full-text articles published from 2000 to 2015 were included in this review of physiological indicators of internet addiction. Finally, 12 articles were selected for review. Results: The theoretical framework developed based on the review proposes that excessive internet use itself may induce physiological stress responses with an increase of stress-related hormones and neurotransmitters. Prolonged abnormal responses of these physiological features produce negative structural and functional changes in the prefrontal cortex, which is mainly involved in cognitive and executive functions. These changes may result in decreased cognitive function. As a stressor, excessive internet use leads to transforming voluntary use into involuntary, habitual use and thus promotes the development of internet addiction. Conclusion: The proposed theoretical framework encompasses cognitive processes that may contribute to the effects of internet use-induced physiological stress on internet addiction. We believe that this framework has important implications for developing cognitive behavioral strategies for internet addicts.

Objective: This study aimed to explore a veteran patients' behavior of prescribing drug use and of which influencing factors from the veteran patients' perspective through qualitative interviews. Methods: We recruited veteran patients through purposive sampling and interviewed 30 veteran patients aged 20 and over who had been taking prescription drugs. We developed and utilized an interview guide consisting of three themes for data collection. We made verbatim transcripts and analyzed data using the framework analysis. Results: Participants were aware that they had large amounts of prescribing medicines and discarded the medicines. They often used improperly by the person himself or his family or acquaintances. The factors that influenced these inefficient prescription drug usage were grouped into 'factors procuring more drugs than necessary' and 'factors being prescribed more drugs than necessary'. Anxiety about downgrading from the upper class to the lower among reward classes for veterans, and suspicion or dissatisfaction with the veteran policy caused the participants to procure more drugs than necessary. Additionally, they received too many medicines due to long-term prescriptions and lack of communication with their doctors, and poor quality of veteran health services. Conclusion: To improve the medication use behavior of veteran patients, providing information or introducing interventions for the proper medication use is not enough. Efforts should be made to improve their negative recognition over relevant policies and health care services.

The purpose of this study is to establish the management plannings for the conservation and environmentally friendly use of Korean coastal wetlands. The function, economic value, and the necessity for the conservation of coastal wetlands are described. The current management status, Korean Governmental policies for the use of coastal wetlands, and their problems are surveyed and analysed. The management plannings for the environmentally friendly use of Korean coastal wetlands is suggested as follows: (1) The coastal wetlands need to be divided into 3 different regions based on PSR(Pressure, State, Response) of OECD. (2) Each region should be managed by appropriate management plans which are suggested in Chapter IV of this paper. Finally, in order to realize these management plannings the change of Governmental system and laws are suggested as follows: (1) The change of relevant laws is required. Additionally, each region should managed by proper governmental agencies. (2) The EIA(Environmental Impact Assessment) system should be improved. (3) The participation of regional people should be guaranteed in the decision making processes of the business and other important planning regarding coastal wetlands. (4) The system which primed the ecological value of coastal wetlands should be established.
