Object : This research was performed to investigate the protective effect of Aurantii Immaturus Fructus against ischemic damage using PC12 cells and global ischemia in gerbils. Methods : To observe the protective effect of Aurantii Immaturus Fructus on ischemia damage, viability and changes in activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase and production of malondialdehyde (MDA) were observed after treating PC12 cells with Aurantii Immaturus Fructus during ischemic insult. Gerbils were divided into three groups : a normal group, a 5-min two-vessel occlusion (2VO) group, and an Aurantii Immaturus Fructus administered after 2VO group. The CCAs were occluded by microclip for 5 minutes. Aurantii Immaturus Fructus was administered orally for 7 days after 2VO. The histological analysis was performed at 7 days after the surgery. For histological analysis, the brain tissue was stained with 1% cresyl violet solution. Results : The results showed that 1. Aurantii Immaturus Fructus had a protective effect against ischemia in the CAI area of the gerbil hippocampus 7 days after 5-minute occlusion, 2. In the hypoxia/reperfusion model using PC12 cells, the Aurantii Immaturus Fructus had a protective effect against ischemia in the dose of $0.2{\;}\mu\textrm{g}/ml,{\;}2{\;}\mu\textrm{g}/ml{\;}and{\;}20{\;}\mu\textrm{g}/ml$ 3. Aurantii Immaturus Fructus increased the activities of glutathione peroxidase and catalase, 4. The activity of superoxide dismutase (SOD) was increased by ischemic damage, which might represent self protection. This study suggests that Aurantii Immaturus Fructus has some neuroprotective effect against neuronal damage following cerebral ischemia in vivo with a widely used experimental model of cerebral ischemia in Mongolian gerbils, and it also has protective effects on a hypoxia/reperfusion cell culture model using PCq2 cells. Conclusions : Aurantii Immaturus Fructus has protective effects against ischemic brain damage at the early stage of ischemia.

The activities of teaching and learning are to try to reach the lesson object most closely in many ways. Considering that the lesson objects are to get the principle or law of a concept, to acquire the mathematical function, to master it through repeated exercises and to solve mathematical problems, we need many ways to reach such objects. Among the many ways, we can first think of one: the students will learn with curiosity and according to their own ability or advancing level in learning when teachers study and prepare necessary contents enough in advance by using computers, showing the right program to learners' needs. For example, defining definite integral by measuration by parts will help understand measuration by parts well and know the meaning of definite integral correctly, In teaching and learning by the use of this program, the educational effects are expected as follows. 1. It is thought that this program will stimulate the desire for and interest in learning because it used animation and acoustic effect. And voluntary and positive thinking activity will be shown. 2. It is expected that the conviction of formulas will be got and the concept of definite integral will be remembered firmly by showing how to measure the width of circle with the use of measuration by parts in various other ways instead of the ways used at present. 3. It is expected that students will feel the pleasure of mathematics in life when they recognize mathematical facts scattered really in our life rather than mathematical difficulties. 4. It is expected that the repeated review of programs already designed will remove the fear of incomplete parts and help review again. 5. It is certain that positive attitude in life will be formed as teacher-centered class is changed into learner-centered class and unwilling study is changed into self-oriented study. However, I think this program is insufficient for humanbeing-centered education given directly in contact with students on the ground of the variety in mathematical education and applications in many ways. And mechanically inhuman computers leave some solutions to be desired

In Oriental medicine, Five Mental is a concept for understanding of man's mental structure. Spirit and body is inseparable relation in Oriental Medicine. Function of spirit and body is regarded as one in Oriental Medical physiology. Spirit is the essence of a function which an organism reveal, and it is regarded in the same with life. For this reason, identification spirit with life is special feature of Oriental Medicine. In Confucianism, Li(理) refers to nature's discipline, which everything under the sun shares. It is similar to the concept of Shin(神) in a broad sense and Sung(性) is similar to that of Shin(神) in a narrow sense. Confucianism's principle is similar to Oriental medicine's, in that they classify Sung(性) into Gi-Jil-Ji-Sung(氣質之性) and Bon-Yeon-Ji-Sung(本然之性), that Sung(性) acts upon man differently according to his disposition, and that materials have an effect on Shin(神)'s action. According to mind's action, there are Human mind(人心) and Moral mind(道心). Human mind(人心) is defined as a mental action of higher degree and Moral mind(道心) is conceived as a mental action related to body. It is similar to Oriental medicine's principle in which Shin(神) is classified into Hun(魂) and Beak(魄) according to its action. Yi(意) is self-control and application, and Zhi(志) is a conscious state in which basic acts towards the object are fixed regularly. Those are similar to the concepts of Oriental medicine.

In contemporary philosophy, the thinking subject became the dis-constructed subject and there was not left any one center in thinking. On the contrary of this trend, the philosopher Levinas stresses 'an ethics of Otherness' that requires the subject to be responsible for the Other. For Levinas, the Other is not knowable and cannot be made into an object of the self. For Levinas, the irreducible relation, the epiphany, of the face-to-face, the encounter with another, is a privileged phenomenon in which the other person's proximity and distance are both strongly felt. The face of the Other comes toward me with its infinite moral demands while emerging out of the trace. In the movie , when Sachie encounters them, she greets them. She provides them with food and shelter to protect from the dangers of elements. With the help of Sachia, the restaurant becomes a peaceful communal place for her and the Other.

Automatic Generation Control (AGC) has functionally controlled the interchange power flow in order to suppress the dynamic oscillations of frequency and tie-line power deviations as a perturbation occurs in the interconnected multi-area power system. Furthermore, Flexible AC Transmission Systems (FACTS) can effectively assist AGC to more enhance the dynamic stability of power system. So, Static Synchronous Series Compensator (SSSC), one of the well-known FACTS devices, is here applied to accurately control and regulate the load frequency of multi-area multi-source interconnected power system. The research and efforts made in this regard have caused to introduce the Fractional Order Proportional Integral Derivative (FOPID) based SSSC, to alleviate both the most significant issues in multi-area interconnected power systems i.e., frequency and tie-line power deviations. Due to multi-objective nature of aforementioned problem, suppression of the frequency and tie-line power deviations is formularized in the form of a multi-object problem. Considering the high performance of Multi Objective Bees Algorithm (MOBA) in solution of the non-linear objectives, it has been utilized to appropriately unravel the optimization problem. To verify and validate the dynamic performance of self-defined FOPID-SSSC, it has been thoroughly evaluated in three different multi-area interconnected power systems. Meanwhile, the dynamic performance of FOPID-SSSC has been accurately compared with a conventional controller based SSSC while the power systems are affected by different Step Load Perturbations (SLPs). Eventually, the simulation results of all three power systems have transparently demonstrated the dynamic performance of FOPID-SSSC to significantly suppress the frequency and tie-line power deviations as compared to conventional controller based SSSC.

Recently there has been an increasing demand for developing a domestic software (S/W) for infrared signature generation to prevent technology leakage and match the domestic operating environment. In this study, we developed a S/W for infrared signature generation and presented its structures and functions for creating and analyzing the IR images of designated spectral bands. The proposed S/W generates IR images of an object through calculations of surface temperatures and IR signals including the self-emitted, surface reflected and path dependent radiances. Moreover, the proposed S/W includes the features of infrared threat analyses from the generated IR images including the infrared contrast radiant intensity (CRI), detection ranges or detection probability analyses, unlike the imported, commercial infrared signature generation S/W.

The view point of the library is treated as a first subject. This study is scheduled to construct, as a experimental study, the system of the Library Science. The study of this fields is called upon greatly because the trial to understand library as a socio-cultural phenomenon did not study as many times. As a result of the study, library is defined as ${\ulcorner}Structural Formation of Inquirying Behavior{\lrcorner}$. Not only technique and actual proof are possible in this study but also this definition is technical definition to indicate the main phenomenon of Librarial Behavior. This schedule represent the trial to define Library Behavior which could anticipate and fabricate when we analyze this definition First, we can find out, first of all, the researching behavior among the human behaviors and then human behavior has the condition of practice. At last, researching behavior can not have any result when it is a natural situation, it has only the meaning when it is guided by an obvious intention. The object of the library is just this human behavior. Second, Formation permits the guidance and self-control at the same-times. The answer about what we find out and practice make it possible the act of guidance. This guidance can't burden any subject but permit the people to result his own researching behaviors. He can save his activities, his own researching behaviors by the result of it. Third, The statematical means efficient performances, and them efficient performances is impossible, here is 'discoveries' of behavior itself. The system of the library is the formation of the relation between the accumulated civilizations and accumulated civilizations. As the definitions of the above mentions, library has the big abilities to the creation and succession of the civilization. As the contemporary view-points, there are some questions about the above described definition can meet it of the library. When we frame the science of library as the learning systems, we can't but the library as this definitions.

This study suggested that the concept of creative zone raised by the national interest of the 'Creation' should be extended in public libraries. The concept of creative zone in public libraries was analyzed on the basis of 'Con-creative structure ontology' by Rombach. As we understand a creator and creation as the relation of 'subject'-'object', The current concept of 'Creation' dilutes the possibility of 'Autogenese' that all beings as a subject possess. But 'Con-creative Structure' describes the process of 'Autogenese' through sharing and mutual communication of all beings. The formation process of Con-creative Structure corresponds to the philosophy of the library that supports the self-growth through communication and sharing. 'Co-working Space' is more suitable for the substantive image of Con-creativity than 'Makerspace'. Therefore, this study analyzed circumstances of creative zone in public libraries and Co-working Space in business areas and provided the conceptive and substantive modeling for Co-working Space in public libraries.

This paper proposes a computer vision and deep learning-based technique for surveillance camera system for vehicle counting as one part of parking lot management system. We applied the You Only Look Once version 2 (YOLOv2) detector and come up with a deep convolutional neural network (CNN) based on YOLOv2 with a different architecture and two models. The effectiveness of the proposed architecture is illustrated using a publicly available Udacity's self-driving-car datasets. After training and testing, our proposed architecture with new models is able to obtain 64.30% mean average precision which is a better performance compare to the original architecture (YOLOv2) that achieved only 47.89% mean average precision on the detection of car, truck, and pedestrian.

Problems of housing, healthcare, social exchanges, and lonely feelings of vulnerable social groups such as the elderly living alone in rural and fishing villages should be resolved by guaranteeing minimum residential rights and levels to restore the sense of self-esteem and social stability and to maintain the rural communities and these should be the object of social interest and support. The housing problems of rural and fishing villages should be resolved not through supply to meet demand but by beginning with providing the ways to attain mutual interaction through the program that recognizes housing as merit goods to maintain the regional communities This research examines more minutely the problems caused by poor housing conditions of rural and fishing villages and attempts to present rural and fishing village type community living home as an alternative through regeneration. The results of this research are as follows. First, the administrative support system should be built to support the community living home in its beginning, process, completion, and even post management. Second, education for reinforcing capabilities to help understand the community living home should continually conducted on the occupants, villagers, and related organizations. Third, in order to expand the community living home, research and development should be made so that the zero-energy house, the alternative energy utilizing house, etc. can be widely used. In building community living home for vulnerable social groups in rural and fishing villages, practical alternatives suitable to the regional realities should be presented and practiced so that the community living home can be built to the satisfaction of all the villagers and the occupants, and the improvement measures should be presented through constant interest and monitoring.
