Purpose: The purposes of this study were to compare confidence in practice of intermittent gavage tube feeding and participants' satisfaction by three types of feedback; professor verbal feedback, professor feedback with smartphone video, and peer feedback with smartphone video. In addition, frequently failed items in the intermittent gavage tube feeding procedure were analyzed. Methods: Data were collected from a convenience sample of 78 nursing college students in November 2014. Students were randomly assigned to the control group, experimental group I (smartphone video with professor feedback) or group II (smartphone video with peer feedback). Data were analyzed using descriptive statistics including chi-square test, ANOVA, and Scheffe test with SPSS 21.0. Results: Confidence in practice of intermittent gavage tube feeding and satisfaction with feedback were highest in experimental group I that had professor feedback with smartphone video. For the procedure, the most frequently failed item was giving an explanation to patients about the purpose and the procedure of tube feeding. Conclusion: The results indicate that professor verbal feedback with smartphone video is the most benefit to the nursing students in acquiring core nursing practice skills.

The interaction of a travelling shock with the shear layer of a flat plate is studied computationally. The Euler and Navier-Stokes equations are solved numerically on quadrilateral unstructured adaptive grids. The flat plate is installed horizontally on the central axis of a shock tube. The shear layer is first created by two shock waves at different speeds splitted by a flat plate. A series of small vortices is developed as a consequence in the shear layer. The shock wave reflected at the end wall impinges the shear layer. The complicated shock dynamics in the evolution to the pseudo-steady state is represented with the morphological transformation of a planar shock into an oblique shock.

Lindsay (1994) and Basu et al (1997) show that another density-based distance called the negative exponential disparity (NED) is an excellent competitor to the Hellinger distance (HD) in generating an asymptotically fully efficient and robust estimator. Bhattacharya and Basu (1996) consider estimation of the locations of several normal populations when an order relation between them is known to be true. They empirically show that the robust HD based weighted likelihood estimators compare favorably with the M-estimators based on Huber's $\psi$ function, the Gastworth estimator, and the trimmed mean estimator. In this paper we investigate the performance of the weighted likelihood estimator based on the NED as a robust alternative relative to that based on the HD. The NED based estimator is found to be quite competitive in the settings considered by Bhattacharya and Basu.

The purpose of this study was to identify and categorize the space use characteristics of the university professor's office. The data were recorded and collected through the physical trace method. Acture Measurement. Photograph, sketch and CAD drawings were used to trace 118 professors offices at Yonse-University. The analysed features were the user characteristics, the size, characteristics of space (such as composition, layout and furniture arrangement), the appliance and the instrument characteristics. To categorize the 'space use' characteristics. 6 variables were used: 1) the territorial characteristics, 2) the spatial relationship between professor's territory and entrance, 3) the layout type of work area, 4) the spatial relationship between professor's and assistant's work area, 5) the arrangement of table, and 6) the completion of sofa set. The results of this study are expected to be used as a basis for the development of design alternatives for the most typical university professors' office.

This is an interview with Professor Kwang-Hyung Lee, founding Dean of KAIST Moon Soul Graduates School of Future Strategy and founder of the Department of Bio and Brain Engineering of the same university casting two questions about academics. The first question is what pattern is desirable in the evolution of research topics of an academics. While traditional researchers in science and engineering tend to focus on one subject in ever greater depth over time, Professor Lee's research agenda has spanned several new topics by gradually changing the content of the study: from artificial intelligence to bio and brain research, and to creativity development method, further to future study. The second question is about researchers' social responsibility. He has devoted to contributes to industry fields and the nation through academic activities as well as educating several successful business people, founding a new academic department and graduate school of future studies.

In this paper we consider the properties of group divisible designs and triangular designs which belong to linked block designs. These designs have minimum number of experiments among the same average efficiency factor Optimal complete diallel cross designs are constructed by these designs. A list is prepared of all linked block designs in the class of group divisible designs and triangular designs enumerated by Clatworthy(1773).

한반도 중부지방의 사면형성과정을 검토하기 위하여 이 지역에 광범위하게 분포하는 쥬라기의 화강암과 선캄브리아기의 편마암으로 구성된 산지 소유역에서 수문관측을 실시하였다. 화강암 유역의 면적은 0.0546$\textrm{km}^2$이며, 기복비는 0.35이다. 편마암 유역은 다소 넓어 면적은 0.0754$\textrm{km}^2$이나 기복비는 0.36으로 거의 같다. 두 유역의 사면은 모두 사림으로 피복되어 있다. 관입시험 결과에 의하면 화강암유역 토층의 층후는 20cm 이하로 얇고 도처에 기반암이 보출된다. 반면에 편마암 유역의 층후는 50cm 이상으로 상대적으로 두껍게 나타난다. 관측은 1999년 5월부터 시작하였으며, 현재도 계속되고 있다. 강우에 대한 유출방응은 편마암 유역이 화강암 유역에 비하여 신속하게 나타난다. 첨두유량과 기저유량 모두 화강암유역보다는 편마암유역에 전반적으로 높게 관측되어 편마암 유역 사면에서의 저류량이 큰 것으로 생각된다. 또한 편마암사면에서 우수의 체류시간을 반영하여 전기전도도는 편마암 유역이 화강암유역보다 2배 정도 높게 관측된다.

Fast Fourier Transformation is employed to convert the head variation of a pipeline in the time domain to the amplitude of the frequency domain. Applying method of characteristics to a pipeline provides a significant frequency range for a surge introduced from the valve modulation. Inverse Fast Fourier Transformation and a Finite Impulse Response Filter can be used to remove any possible noise existing from the significant frequency range of an unsteady condition. A filtered signal shows higher potential for the inverse calculation of leakage detection than the noise-added signal does. The respective performances of Inverse Fast Fourier Transformation and a Finite Impulse Response Filter are compared in terms of leakage detection capability. Characteristics of the frequency range for multiple leakages were investigated to validate the effectiveness of the noise control method in the frequency domain.

The problem of separation between the teaching and the practice of architectural design in Korean universities has activated this study. Comparison between two professor-architects in Italy through their various activities has been made during the period of 1991-1992 in the Istituto Universitario di Architettura di Venezia. The names of the two professor-architects are Aldo Rossi and Franco Mancuso. Their teaching activities in their architectural design class with their assistants, their background and formation of architectural theory, and two realized (and prized) works of them have been compared. The results show that there is a great difference (or oppositions) in their world-view and their attitudes towards architecture, the one as an empiricist, the other as a rationalist. But the most impressive observation must be the fact that all of them were coherent in their teaching, theory and practice, although this raises another qustion about the 'rationality' in architecture.

This study introduces and empirically test the validity of Bass model that helps demand forecasting of new game products. The application of Bass model to new game products show that Bass model predicts the demand of new game accurately. In particular, it showed very good predictability of on-line game products.
