An adult one-year-old male Eurasian beaver (Castor fiber) died of a traumatic injury to its right leg from a fall. At necropsy, fibrinopurulent exudates were observed in the thoracic cavity. Histopathologic examination showed that the pericardium, thoracic wall, pulmonary pleura and the lungs were markedly thickened due to mixtures of necrotic cellular debris, neutrophils, fibrin, red blood cells, and bacterial aggregates. Pure culture of Klebsiella (K.) pneumoniae was isolated from the thoracic exudates, pleura and heart tissues. Based on these findings, this is the first report describing pleuritis and pericarditis associated to K. pneumoniae in a beaver.

The main purpose of this study was to investigate the desiarable selection of nursing. The subjects for this study were made up of 144 R.N. in active service at H. University hospital in Seoul. This study was “Choice of nursing seale”as a tool which was MMPI questionare developed by Beaver（1953）, and was consist of the choice of nursing scals made up to 66 items. The finding of this study related to their personality and their work achievement showed very significant differences： the results of this study are： 1. There was a significance of the difference between the responses of 64 student nurses and 64 College Women in Educations Curricular to Beaver score. (p <.001) 2. There was a significance in Beaver's score between high group(above 82) and low group(below 53) according to head nurses' work achievement score (p <.05) 3. This study had relationship between the personality and the work achievement of nurses. For the reason, I suggest that we had to apply to select the appropriate nurses in Health Field as Hospitals.

In this paper, we propose regression methods based on the likelihood function. We assume Arnold-Beaver Skew Normal(ABSN) errors in a simple linear regression model. It was shown that the novel method performs better with an asymmetric data set compared to the usual regression model with the Gaussian errors. The utility of a novel method is demonstrated through simulation and real data sets.

In this paper, two new inverse regression methods are introduced. One is a distance based method, and the other is a likelihood based method. While a model is fitted by minimizing the sum of squared prediction errors of y's and x's in the classical and inverse methods, respectively. In the new distance based method, we simultaneously minimize the sum of both squared prediction errors. In the likelihood based method, we propose an inverse regression with Arnold-Beaver Skew Normal(ABSN) error distribution. Using the cross validation method with an asymmetric real data set, two new and two existing methods are studied based on the relative prediction bias(RBP) criteria.

Two varieties of alfalfa (Medicago sativa L cv. Pioneer and Beaver) and timothy (Phleum pratense L cv. Climax and Joliette), grown at different locations in Saskatchewan (Canada), were cut at three stages [1=one week before commercial cut (early bud for alfalfa; joint for timothy); 2=at commercial cut (late bud for alfalfa; pre-bloom head for timothy); 3=one week after commercial cut (early bloom for alfalfa; full head for timothy)]. The energy values of forages were determined using three approaches, including chemical (NRC 2001 formula) and biological approaches (standard in vitro and in situ assay). The objectives of this study were to determine the effects of forage variety and stage of maturity on energy values under the climate conditions of western Canada, and to investigate relationship between chemical (NRC 2001 formula) approach and biological approaches (in vitro and in situ assay) on prediction of energy values. The results showed that, in general, forage species (alfalfa vs. timothy) and cutting stage had profound impacts, but the varieties within each species (Pioneer vs. Beaver in alfalfa; Climax vs. Joliette in timothy) had minimal effects on energy values. As forage maturity increased, the energy contents behaved in a quadratic fashion, increasing at stage 2 and then significantly decreasing at stage 3. However, the prediction methods-chemical approach (NRC 2001 formula) and biological approaches (in vitro and in situ assay) had great influences on energy values. The highest predicted energy values were found by using the in situ approach, the lowest prediction value by using the NRC 2001 formula, and the intermediate values by the in vitro approach. The in situ results may be most accurate because it is closest to simulate animal condition. The energy values measured by biological approaches are not predictable by the chemical approach in this study, indicating that a refinement is needed in accurately predicting energy values.

The delta operator approach and the singular perturbation technique are introduced. The former reduces the round-off error in the numerical computation. The latter reduces computing time by decoupling the original system into the fast and slow sub-systems. The aircraft dynamics consists of the Phugoid and short-period motions whether its model is longitudinal or lateral. In this paper, an approximated solutions of lateral dynamic model of Beaver obtained by using those two methods in compared with the exact solution. For open-loop system and closed-loop system, and approximated solution gets identical to the exact solution with only one iteration and without iteration, respectively. Therefore, it is shown that implementing those approaches is very effective in the flight dynamic and control.

The purpose of this paper is to analyze the elementary school students' level of computational thinking ability by analyzing the domestic question and examination results of Beaver Challenge 2017. Based on the results of the 'Challenge' results of Beaver Challenge 2017, the achievement by element, gender, and grade of elementary school students II (elementary school 3.4) and group III (elementary school 5.6) Respectively. As a result of the analysis, the achievement by the evaluation factors showed difference within each group. In addition, there was no significant difference in achievement according to gender except for one area of group II. The achievement level of each grade was statistically significant in the group III. The results of this study are expected to provide implications for the level of students related to what can be evaluated in elementary school information education and contribute to the follow-up research.

In modern aircraft, an autopilot system is getting more important. There are not many autopilot systems applied to small aircraft. Also the autopilot system in large or medium aircraft is difficult to apply to small aircraft directly. It is necessary to make a new autopilot system for small aircraft. In this paper, we implement the small aircraft simulator with autopilot system using SIMULINK. The various modes of autopilot - such as altitude select/hold, attitude hold, heading hold, etc. - are implemented to the flight simulator and tested. We also implement the VOR mode for aircraft guidance.
