Pasteurella multocida에 대(對)한 각종성장(各種性狀) 및 균주(菌株) 상호간(相互間)의 이동(異同)에 관(關)하여는 많은 연구(硏究)가 있으나 아직까지의 문헌(文獻)에 의(依)하면 자연감염(自然感染에)에 있어서는 일반적(一般的)으로 동종동물(同種動物)에 감염(感染)한다 하여도 각종동물(各種動物)에서 분리(分離)된 Pasteurella multocida는 그 병원성(病原性)이 분리(分離)된 동물(動物)과 명확(明確)한 상관관계(相關關係)를 가지는것이 아니며 그저 생물학적(生物學的) 내지(乃至) 생화학성장(生化學性狀) 혹(或)은 면역학적성장(免疫學的性狀)에 있어서 그차이(差異)로 균형(菌型)을 분류(分類)할수 있는데 불과(不過)하다. 그런데 월지(越智)는 그의 분류(分類)에서 A형균(型菌)(조류(鳥類)에서 분리(分離)한 균주(菌株))은 가토(家兎) mouse 및 조류(鳥類)에 병원성(病原性)이 있고 타(他) 포유동물(哺乳動物)에 병원성(病原性)이 없다고 하였으며 또 B. C. D형균(型菌)(포유류(哺乳類))에서 분리(分離)한것)은 닭, 가압등(家鴨等) 조류(鳥類)에 병원성(病原性)이 없다고 하였다. 그러나 필자(筆者)는 출혈성패혈증(出血性敗血症)으로 죽은 오리 및 돈(豚) cholera와 혼합감염(混合感染)을 이르킨 돈(豚)으로부터 각각(各各) 따로 Pasteurella multocida를 분리(分離)하여 이 병균(病菌)를 가지고 각종동물(各種動物)에 접종시험(接種試驗)을 한바 상술(上述)한 월지(越智)의 견해(見解)는 부합(附合)되지 않았다. 즉 이 양주(兩株)는 돈(豚), 가토(家兎), 오리, 닭등(等)에 대(對)하여 동양(同樣)으로 강(强)한 병원성(病原性)을 가졌으며 또 양주(兩株)는 다같이 면양(緬羊)에 대(對)하여 거이 병원성(病原性)이 없고 Guinea Pig은 양주(兩株)에 대(對)한 저항성(抵抗性)이 다같이 강(强)하였다. 다시말하면 이 양주(兩株)는 조류(鳥類)나 포유류(哺乳類)에 대(對)하여 거의 동일(同一)한 병원성(病原性)이 있음을 인정(認定)하였다.

In recent years, embedded systems such as cellular phones, Portable Multimedia Player, intelligent appliance, automobile engine control are reshaping the way people live, work, and play. Thereby, services application to guarantee various requirements of users become increasingly sophisticated and complicated, such embedded computing platforms use real-time operating systems (RTOSs) with time determinism. These RTOSs must not only provide predictable services but must also be efficient and small in size. Kernel services should also be deterministic by specifying how long each service call will take to execute. Having this information allows the application designers to better plan their real-time application software so as not to miss the deadline of each task. In this paper, we present the complete generalized real-time scheduling algorithm using multi-dimensional methodology to determine the highest priority in the ready list with 2r levels of priorities in a constant time without additional memory overhead.

The discussion was started from the question about how literary linguistic expressions are reproduced in the movies. This study focuses on the cinematized version of Jelinek's "Die Klavierspielerin", the by Michael Haneke. and looking for cinematization of literary works and these aesthetic values. The original delicately describes the life of Erika who has been living under the supervision and control by her mother. The topic of the is the conflict between the controlling mother and the desires of the heroin Erika who has been living under the suppression. The world of suppression symbolized by her mother is described as closed and dark space while the world of Erika and her desires, represented by Walter is described as open and bright space. The life of Erika living under control symbolized by prison-like double doors, iron-barred window, darkness and shadow is abnormally distorted. Even the piano that must be the center of her life as a pianist is also one of the symbols of dark world of suppression.

The existing fuzzy traffic controllers construct the rule-base based on the intuitive knowledge and experience or the standard rule-base, but the rule-base constructed by the above methods has difficulty in representing exactly and detailedly the control knowledge of the export and the operator. Therefore, in this paper, we propose a method that can improve the performance of the fuzzy traffic control by designing the fuzzy traffic controller which represents the control knowledge more exactly. The proposed method so modifies the position and shape of the fuzzy membership function based on the input-output data clustering that the fuzzy traffic controller can represent the control knowledge more exactly. Our method use the rough control knowledge based on intuitive knowledge and experience as the evaluation function for clustering the input-output data. The fuzzy traffic controller designed by the our method could represent the control knowledge of the expert and the operator more exactly, and it outperformed the existing controller in terms of the number of passed vehicles and the wasted green-time.

The purpose of this study is to investigate factors related to use-diffusion of Nscreen service as well as consumers' lifestyle and media usage of Nscreen service, which is fundamentally changing both the competitive landscape for business and the daily lives of consumers. The data of 1,524 consumers used in this study were drawn from the first Korea Media Panel Study in 2012 of Korea Information Society Development Institute. This study categorized adopters depending on the usage rate of contents and the variety of media platforms they used. Consumers using various media platforms enjoyed more categories of contents provided by Nscreen services. The variety of media platforms was useful in grouping users to explain the difference between the groups in terms of lifestyle activities. Based on the factor analysis and cluster analysis based on the consumers' lifestyle to find out different characteristics of each clusters, the result elicited some implications.

Although GPGPU (General-Purpose GPU) can maximize performance by parallelizing a task with tens of thousands of threads, those threads are internally grouped into a thread block, which is a base unit for processing and resource allocation. A thread block scheduler is a specialized hardware gadget whose role is to allocate thread blocks to GPGPU processing hardware in a round-robin manner. However, round-robin is a sequential allocation policy and is not optimized for GPGPU resource utilization. In this paper, we propose a thread block scheduler model which can analyze and quantify performances for various thread block scheduling policies. Experiment results from the implemented simulator of our model show that the legacy hardware thread block scheduling does not behave well when workload becomes heavy.

Recently, non-orthogonal multiple access (NOMA) have been received considerable attention to be involved in the next generation mobile system. However, there are inherent inter-user interferences caused by the multiplexing multiple users in the same communication resource in NOMA systems. Two representative methods, the approximate white noise and random variable methods, have been adapted for the analysis of interferences in NOMA systems. In this paper, we derive the outage probabilities of an uplink NOMA system with the two analysis methods and compare the results. The numerical results of the outage probabilities versus transmitted power, distances, and power allocation are compared. We noticed that the derived functions are different each other, but the numerical results are coincident. It is shown that the two interference analysis methods can be applied to the analysis of NOMA systems.

Various imperative statements that can be represented in the way in which the product or service is used describe how or how to achieve the goals, or induce or prohibit a specific action. This study focuses on The Effects of age and type of imperative sentence (directive vs. declarative) on behavioral intention and recall. As a result of the experiment, older people who have shorter lives remaining access information in a more emotional way, so they have been rejected by directive (vs. declarative) statements that felt more negative feelings, resulting in lowered behavioral intention. Conversely, the negative feeling caused by directive statements increased salience of directive (vs. declarative) sentence for older people more, which in turn increased memory for older people. Process analysis showed that emotions when exposed to statements mediated these results. The results of this study show that in order to improve consumers' behavioral response and/or the performance of information processing, it is necessary to deeply consider their age and how to construct the statement.

Software Education will be implemented at elementary, middle and high schools starting in 2018. The goal of software education is to help students develop Computational thinking skills. Especially, using robots in software education increases student interest and helps to increase creativity. In order for software education using robots to be effective, education for teachers should be effective. The development of effective education contents for preliminary teachers can be said to be the success of software education. By the way, effective education can be said to begin with an accurate analysis of the subjects. In order to develop an effective curriculum for preliminary teachers, it is necessary to grasp the level of preliminary teachers who will carry out the software education using robots. Therefore, in this paper, we surveyed the experiences, levels and perceptions of preliminary teachers to help develop software education curriculum using robots.

Recently, it has been continually researched that the advertising regulation should be tightened since suggestive advertising in Internet affect more negatively juveniles. Most of the researches seem to overlook an important fact that the objects of the researches, suggestive advertising are different from the harmful advertising to juveniles defined by the Juvenile Protection Act because they approached with ethical perspectives, not legally. It can be judged that the suggestive advertising in the past researches are not actually harmful advertising regulated by the Act, so the suggestive advertising should be properly managed for protecting juveniles, not banned. In this context, this study suggested that more proper and reasonable advertising regulations in Internet environment for protecting juveniles, with reviewing the problems of regulation system of media product harmful to juveniles, focusing on the differences between 'suggestive' and 'harmful' advertising to juveniles by the Act.
