  • Today, a computational thinking course is being introduced in elementary, secondary and higher education curriculums. It is important to encourage a creative talent built on convergence of computational thinking and various major fields. However, proper analysis and evaluation of computational thinking assessment tools in higher education are currently not sufficient. In this study, we developed a rubric to evaluate computational thinking skills in university class from two perspectives: conceptual learning and practical programming training. Moreover, learning achievement and relevance between theory and practice were assessed. The proposed rubric is based on Computational Thinking Practices for assessing the higher education curriculum, and it is defined as a two-level structure which consists of four categories and eight items. The proposed rubric has been applied to a liberal art class in university, and the results were discussed to make future improvements.

  • This study aims to review the research trends concerning environmental psychology. The scope of review is limited to the papers that dealt with theoretical and case-directed investigation research about the relationship between socio-physical environments and human beings. The relationship has been investigated by diverse human reactions such as cognitive, emotional, analytical, behavioral, and comprehensive. 219 papers were reviewed in two steps. In the first step, the ratio of the papers in the field of environmental psychology to the total papers published in the Journal from 1973 to 2004 was analyzed. Second, all the 219 papers were classified by such three criteria as the type of the paper(theoretical, review, case investigation), the methodology taken, and the main theme of the paper. The main findings from the review are summarized as follows; 1. Out of the 219 papers, the number of the theoretical papers was 4 (1.8%), whereas the number of the case investigation papers was 185 (84.5%). 2. Out of the 30 review papers, the main methodology used was simple introduction (15 papers, 50%) and the main theme was research methodology (36%), whereas analytic comparison was used only in 10 papers (33%) and theory review was only found in 6 papers (20%). 3. Out of the 185 case investigation papers, experimental method was found in 34 papers (18%), whereas 99 papers used correlational method (54%). Based on the findings, it was suggested that both theoretical and case-directed research should be performed in order to enhance the state of art in environmental psychology. Theoretical research as a framework to understand the empirical findings are as important as the case-investigation research peformed by scientific experimental method.

  • In order to use analog more systematically in science class, an instructional model was designed on the basis of analogical reasoning processes (encoding, inference, mapping, application, and response) in the Sternberg's component process theory. The model has five phases (introducing target context, cue retrieval of analog context, mapping similarity and drawing target concept, application, and elaboration), and the instructional effects of using the model upon students' comprehension of science concepts and motivation level of learning were investigated. The treatment and control groups (1 class each) were selected from 8th-grade classes and taught about chemical change and chemical reaction for the period of 10 class hours. The treatment group was taught with the materials based on the model, while the control group was taught in traditional instruction without using analog. Before the instructions, modified versions of the Patterns of Adaptive Learning Survey and the Group Assessment of Logical Thinking were administered, and their scores were used as covariates for students' conceptions and motivational level of learning, respectively. Analogical reasoning ability test was also administered, and its score was used as a blocking variable. After the instructions, students' conceptions were measured by a researcher-made science conception test, and their motivational level of learning was measured by a modified version of the Instructional Materials Motivation Scale. The results indicated that the adjusted mean score of the conception test for the treatment group was significantly higher than that of the control group at .01 level of significance. No significant interaction between the instruction and the analogical reasoning ability was found. Although the motivational level of learning for the treatment group was higher than that for the control group, the difference was found to be statistically insignificant. Educational implications are discussed.

  • For the better understanding of the temporal characteristics of soil water, this study is to suggest a stochastic soil water model and to apply it for impact assessment of climate change. The loss function is divided into 3 stages for more specified comprehension of the probabilistic behavior of soil water, and especially, the soil water model considering the stochastic characteristics of precipitation is developed in order to consider the variation of climatic factors. The simulation result of soil water model confirms that the proposed soil water model can re-generate the observation properly, and it also proves that the soil water behaves with consistent cycle based on the precipitation pattern. Moreover, with the simulation results with a climate change scenario, it can be predicted that the future soil water will have higher variations than present soil water.

  • The out-of-plane response of infill walls has recently gained a growing attention and has been recognised fundamental in the damage assessment of reinforced concrete and steel framed buildings subjected to seismic loads. The observation of damage after earthquakes highlighted that out-of-plane collapse of masonry infills may occur even during seismic events of low or moderate intensity, causing both casualty risks and unfavourable situations affecting the overall structural response. Even though studies concerning the out-of-plane behaviour of infills are not as many as those focused on the in-plane response, in the last decades, a substantial number of researches have been carried out on the out-of-plane behaviour of infills. In this study, the out-of-plane response is investigated considering different aspects. First, damages observed after past earthquakes are examined, with the aim of identifying the main parameters involved and the most critical configurations. Secondly, the response recorded in about 150 experimental tests is deeply examined, focusing on the influence of geometrical characteristics, boundary conditions, prior in-plane damage, presence of reinforcing elements and openings. Finally, different theoretical capacity models and code provisions are discussed and compared, giving specific attention to those based on the arching theory. The reliability of some of these models is herein tested with reference to experimental results. The comparison between analytically predicted and experimental values allows to appreciate the extent of approximation of such methods.

  • In this study, a space-time rainfall grid field generation model based on multifractal theory was verified using nine flood events in the upstream watershed of Chungju dam in South Korea. For this purpose, KMA radar rainfall data sets were analyzed for the space-time multifractal characteristics. Simulated rainfall fields that represent the multifractal characteristics of observed rainfall field were reproduced using the space-time rainfall grid field generation model with log-Poisson distribution and three-dimension wavelet function. Simulated rainfall fields were applied to the S-RAT model as input data and compared with both observed rainfall fields and low-resolution rainfall field runoff. Error analyses using RMSE, RRMSE, MAE, SS, NPE and PTE indicated that the peak discharge increases about 20.03% and the time to peak decreases about 0.81%.

  • Recent changes in health problems as well as the health delivery system demand expanding nursing roles to improve quality care and at the same time provide cost-effective health services. Nursing leaders of the future will be expected to be excellent care givers who are well prepared as researchers and managers and administrators. The purpose of developing an ND program is to train nursing leaders for the future. The program objective are to demonstrate the role as 1) an advanced practitioner who will provide theory based practice 2) a researcher and manager The target population of the ND program is as follows : 1) Nurses with a BSN degree who are seeking to advance on the career ladder 2) Non-nursing BS, BA graduates who are seeking nursing as a second career 3) Transfer students who are mature and motived to be nursing leaders It is believed that the ND program would meet the diverse needs for potential students, for their role in nursing and the health delivery system and create a meaning and challenging position in the profession of nursing. A task force team was organized to develop the ND program and its activities are as follows; 1) Information on ND programs were collected from 3 universities and reviewed 2)An advanced education needs assessment was completed and it was found that 87.6% of the subjects responded positively about advanced degree work. 3) A tentative curriculum for an ND program was developed. It is a great challenge to develop a new program for nursing however, it is also our task and responsibility to further the development of nursing.

  • Background Achieving symmetry is a key goal in breast reconstruction. Anatomically shaped tabbed expanders are a new tool in the armamentarium of the breast reconstruction surgeon. Suture tabs allow for full control over the expander position and thus inframammary fold position, and, in theory, tabbed expanders mitigate many factors responsible for poor symmetry. The impact of a tabbed expander on breast symmetry, however, has not been formally reported. This study aims to evaluate breast symmetry following expander-implant reconstruction using tabbed and non-tabbed tissue expanders. Methods A chart review was performed of 188 consecutive expander-implant reconstructions that met the inclusion criteria of adequate follow-up data and postoperative photographs. Demographic, oncologic, postoperative complication, and photographic data was obtained for each patient. The photographic data was scored using a 4-point scale assessing breast symmetry by three blinded, independent reviewers. Results Of the 188 patients, 74 underwent reconstruction with tabbed expanders and 114 with non-tabbed expanders. The tabbed cohort had significantly higher symmetry scores than the non-tabbed cohort ($2.82/4{\pm}0.86$ vs. $2.55/4{\pm}0.92$, P=0.034). Conclusions The use of tabbed tissue expanders improves breast symmetry in tissue expander-implant-based breast reconstruction. Fixation of the expander to the chest wall allows for more precise control over its location and counteracts the day-to-day translational forces that may influence the shape and location of the expander pocket, mitigating many factors responsible for breast asymmetry.
