  • This article is to investigate the possibility that project-based classes introducing mobile phones can replace the monotony of traditional classes led by teachers as well as they can encourage students to take active part in the classes to some extent. The students in groups choose a genre for their own video projects (e.g., movie, drama, news, documentary, and commercial) and produce the video contents using a mobile phone for presentation made at the end of a semester. In the sense that the students are allowed to do video-based mobile phone projects, they can work independently outside of class, where time and space are more flexible and students are free from the anxiety of speaking or acting in front of an audience. A mobile phone project consists of around five stages done both in and outside of the classroom. All of these stages can be graded independently, including genre selection, drafting of scripts, peer review and revision, rehearsals, and presentation of the video. Feedback is given to students. After the presentation, students filled out a survey questionnaire sheet devised to analyze students' responses toward preferences and level of difficulty of the project activity. Finally, proposals are made for introduction of a better mobile phone-based project classes.

  • Objectives: This article examines the diversity of healthy cities evaluation in practice and discusses the major conflicting issues in evaluating healthy cities to offer implications to academics and cities for application in their field. Methods: The author discusses issues on major topics that arose from a review of literature on selected articles from peer-reviewed journals, books and gray literature. The recently developed Korean Healthy Cities evaluation framework is used as a main source of reference. Results: Evaluating healthy cities is in itself a political process and requires multiple methodologies and diverse sources of data. Details of the evaluation process depend on the purposes and goals predetermined by the stakeholders. The Korean Healthy Cities evaluation framework applies these principles and suggests a participatory approach to evaluation, selection of indicators that provide evidence on the process of change and to use mixed evaluation methods. The involvement of stakeholders in the evaluation process can also be a useful tool to further strengthen partnerships and strategies for healthy cities. Conclusion: Cities need to engage more in evaluation activities and develop necessary skills and capacity to produce utility-driven evidence.

  • Objectives: This study aimed to analyze research trends in autism spectrum disorder (ASD) and savant syndrome and their cognitive characteristics through a systematic literature review. The objectives of this study were to establish an overview of research trends in ASD and savant syndrome, analyze the overall characteristics of individuals with ASD and savant syndrome, and examine their cognitive characteristics. Methods: For the systematic literature review, three criteria were used to select review articles: 1) literature from peer-reviewed journals, published in the past 15 years, from 2008 to 2022; 2) subjects with ASD and savant syndrome; 3) study objectives focused on the basic phenomenon and cognitive characteristics of ASD and savant syndrome. Finally, based on the selection criteria, a total of 40 articles were included. Results: Five themes and nine subthemes were derived from the analysis of 40 studies. The five main themes were as follows: 1) What is savant syndrome? 2) Demographic characteristics of savant syndrome; 3) Spectra of savant syndrome; 4) Savant syndrome and ASD; and 5) Cognitive characteristics of ASD with savant syndrome. The subthemes of the cognitive characteristics were weak central coherence, detail-focused cognitive processing, enhanced perceptual functioning, and hyper-systemizing. Conclusion: Several studies have been conducted to understand ASD and savant syndrome; however, no single theory can specify the cognitive characteristics of people with ASD and savant syndrome. Therefore, further systematic and multi-layered research on ASD and savant syndrome are required for more comprehensive results.

  • Purpose - This study aims to examine the role of contract law in mergers and acquisitions (M&A) and to examine whether or not contract law is necessary in M&A. The study also discusses how contract law can be utilized in M&A, as well as some of the problems that arise from the use of contracts in this area. Research design, data, and methodology - To minimize bias and errors, this study used only peer-reviewed articles and book excluding internet news articles, conference papers, and dissertations. For a well-organized screen and selection process, the author conducted the extraction procedure thoroughly to eliminate some duplicated resources. Result: This study indicates that complex deals carry a high risk but also have the potential to yield substantial revenue for stakeholders. Thus, contract law is essential to the success of M&A because it helps to define the (1) terms of the transaction, (2) reduces risk, (3) offers legal safeguards, and ensures that the (4) agreement is enforced. Conclusion - This study concludes that an understanding of contract law is essential to the profitable merging of two businesses. The application of contract law provides a mechanism for enforcing the agreement, which can increase the likelihood that the stipulations of the M&A will be satisfied.

  • Groundwater in the Waikatoregion is a valuable resource for agriculture, water supply, forestry and industries. The 434,000 ha study area comprises the upper Waikato River catchment from the outflow of Lake Taupo (New Zealand's largest lake) through to Lake Karapiro (a man-made hydro lake with high recreational value) (Figure 1). Water quality in the area is naturally high. However, there are indications that this quality is deteriorating as a result of land use intensification and deforestation. Compounding this concern for decision makers is the lag time between land use changes and the realisation of effects on groundwater and surface water quality. It is expected that the effects of land use changes have not yet fully manifested, and additional intensification may take decadesto fully develop, further compounding the deterioration. Consequently, Environment Waikato (EW) have proposed a programme of work to develop a groundwater model to assist managing water quality and appropriate policy development within the catchment. One of the most important and critical decisions of any modelling exercise is the choice of the modelling platform to be used. It must not inhibit future decision making and scenario exploration and needs to allow as accurate representation of reality as feasible. With this in mind, EW requested that two modelling platforms, MODFLOW/MT3DMS and FEFLOW, be assessed for their ability to deliver the long-term modelling objectives for this project. The two platforms were compared alongside various selection criteria including complexity of model set-up and development, computational burden, ease and accuracy of representing surface water-groundwater interactions, precision in predictive scenarios and ease with which the model input and output files could be interrogated. This latter criteria is essential for the thorough assessment of predictive uncertainty with third-party software, such as PEST. This paper will focus on the attributes of each modelling platform and the comparison of the two approaches against the key criteria in the selection process. Primarily due to the ease of handling and developing input files and interrogating output files, MODFLOW/MT3DMS was selected as the preferred platform. Other advantages and disadvantages of the two modelling platforms were somewhat balanced. A preliminary regional groundwater numerical model of the study area was subsequently constructed. The model simulates steady state groundwater and surface water flows using MODFLOW and transient contaminant transport with MT3DMS, focussing on nitrate nitrogen (as a conservative solute). Geological information for this project was provided by GNS Science. Professional peer review was completed by Dr. Vince Bidwell (of Lincoln Environmental).

  • The purpose of this study is to develop teaching and learning materials for the mathematics project inquiry subject. Since this subject is newly opened in the 2015 revised mathematics curriculum, there are no textbooks and materials. Hence it is required to help teachers plan lessons of the mathematics project inquiry subject. For this study, developing directions and objectives are established. Ten hours of lesson plan and teaching and learning materials are also developed for the two themes of 'big data' and 'industrial mathematics'. Suitability and validity of the developed material are verified positively from a survey of 8 teachers and 2 professionals. The detailed result findings are as follows. First, teaching and learning notes are suggested for each lesson plan. They are comprised of building inquiry plan, doing inquiry, summarizing results, and presentation. Second, driving questions of each theme are developed as "What is the big data and where is it used for ?" and "How various is the use of the industrial mathematics ?" respectively. Third, poster-types of each project product are developed. Fourth, three inquiry activity sheets and examples which are theme selection, inquiry plan, and group activity are developed. Fifth, 4 assessment sheets of self, peer, group, and teacher-use are developed.

  • I. Objectives This study was done to analyze and evaluate the attitudes of the working mothers toward the care of infants in group settings. II. Method and Procedures 1. Standardized questionnaire were sent out to look into the following: 1) the attitude of working mothers, who have infants below 4 years of age, regarding their job, care-taker and group settings. 2) the status of taking care of their infants 2. Subjects Women teachers of Seoul and Kyung Ki primary school districts, who have infants below age 4. The selection of these subjects were done by random sampling. III. Results 1. Attitudes regarding their jobs: The first reason for retaining their jobs are for financial reasons; whereas, their intents of self-actualization and contributions to society comes next. 2. The Status of Caretakers 60.7% of the care-takers are family-related members, and 38.3% are not. The educational level of caretakers are as follows, with 19.6% of the caretakers without any formal education, 44% with primary education, and 18.7% having high school education. The reasons for the dissatisfaction by the caretakers are low education, a frequent change of caretaker, and an attitude without affection. The cost of child caring is high, the main reason being the heavy expense spent on the caretakers. 3. Attitudes of care in group settings: 85.9% of the subjects responded with positive reactions for the necessity of having group-settings. The reasons given for the importance of having a group setting are early experience, social interaction with peer group and educational functioning, in addition to protective care. They desire for a family-style care which can raise infants under high quality of care.

  • Injury has now replaced disease as the biggest single cause of death in children after their first birthday. Each day child dies from preventable, unintentional injury and the medical cost of these injury is increasing remarkably. It is necessary to develope injury prevention models to explain, predict, manage, evaluate and analyze the information about accident. The purpose of this paper is, firstly, to investigate parent's actions regarding safety measures at home and secondly, to identify the influencing factors of parents' safety behaviors. The selection of such factors is guided by the theoretical framework of the Pender's Health Promotion Model. Method ; The questionnaire was developed on the basis of other investigations, through pilot testing, peer review, and review by field health workers. The questionnaire was completed by 231 mothers of young children. Data was collected between April and May 2002. Variable Use of three different domains of safety behavior, safety habits, supervision and perception of safety devices, were listed. Mothers were self reported on internal locus of control, mother & child relationships, and marital intimacy. Also the elements of the Health Promotion Model: perceived benefit, barrier, threat, and self-efficacy, were surveyed. Results & discussion The results indicate that most parents take considerable action to reduce household hazards. The constructs derived from the Model were statistically significant differences for a small part of the variables on parental behavior to reduce hazards in the home, such as age, education, economic status, self-efficacy, perceived benefit, internal locus of control. Future studies ought to include social influences, such as expectations, perceived norms, knowledge, and child-related variables, relevant to parental safety measures in their home.
