In this paper, I investigate on the human nature in philosophy of Wang Yang-Ming and Buddhism from a Kantian point of view. The core argument of the philosophy of Wang Yang-Ming, Buddhism and Kant is that all human beings have the pure abilities a priori to overcome themselves, to realize their own potentialities. This is called immanent transcendence. At this time human beings can be free. Kant, Wang Yang-Ming and Buddhism claim that all human beings themselves will overcome their desires from their mind and body through the immanent transcendence, reflection and contemplation on their own. When we give up the external knowledges, throw away obsessions with the selfish desires and go back to our inside, we can see our original nature. To have an insight into this inner nature, to respect the moral law a priori, this is to overcome the ourselves, and to be a Grate Man(聖人) and a Buddha. This way is the only way to be a Grate Man and a Buddha. The main proposition of Wang Yang-Ming's philosophy is expressed 'There are no things without mind.'(心外無物) The core of Kant's transcendental philosophy is called the Copernican Revolution by himself. Copernican Revolution means the transition from the object-centered epistemology to the subject-centered epistemology. 'Innate Knowing'(良知) and 'Perform Innate Knowing'(致良知), 'All human beings have the mind of Buddha'(一切衆生悉有佛性) contain the apriority, immanence of Moral Law. In this respect, the theory of Innate Knowing in Wang Yang-Ming and mind of Buddha in Buddhism, pure Moral Law in Kant has the same structure grounded in subjectivity. Even if we have the mind of Buddha, innate Knowing, moral law a priori, the reason why we don't know our original nature is that we fall into the obsessions with selfish desires, and that we have inclination to external interests. So the moment you see our original nature, ordinary people themselves turn into a Buddha. These changes and transitions are immanent transcendence. All human beings have the ability to do this changes and transitions. Buddha does not exist outside of us, but it exists with our reflections on our human nature. Buddha can not existed without our insight into the our innate Ego. Where there is our original nature, there is a Buddha. So Buddha is called the another name of the original figure of human beings.

In recent time, archival science has been in charge of positively preserving and handling with valuable things, as well as managing established ones, However, even though several archival methodologies that manage contexts among tasks, organizations and subjects exist nowadays, there is a lack of theoretical methodology on archiving focusing on valuable things. In this sense, this article dealt with a theoretical methodology which carries out archiving valuable things and represents it based on the value of records. Also, this paper, which covers a methodology that carries out archiving and representing one focusing on the value of the one to preserve, is divided into three chapters: putting in, managing, and viewing. To begin with, in the chapter of purring in, the methodology of documentation based on a strategy to distinguish and represent the value of the valuable things were explained. In addition, the article tried to explain the definition of how the valuable things based on the value of it can be put in, and presented how to divide the one for representation into the objet and the activity so as to provide an effective approach. At the same time, as this paper took an approach to the value of the one, it proposed a way to be able to do archiving effectively by applying a representation unit which has its own value. Secondly, in the chapter of managing, representation class and metadata for managing with a representable structure was considered. Metadata categories were illustrated in order to present the class from individual records to final representation valuable things and to make representation with ease. Furthermore, in the chapter of viewing, the process of representation using theoretically archived records was explained. In fact, viewing is the descriptive domain in general, yet this paper focused on the conceptional part. As a consequence, in this paper, a series of process was considered, which starts from how the subject of representation was archived to managing it. Moreover, the process has a meaning by itself in that it gives a practical method to be applied. Finally, the paper suggested that the argumentation on representation be expanded in the field of archival science so as to present theoretical grounds in this sort of work.

Stormwater runoff containing considerable amounts of pollutants such as particulates, organics, nutrients, and heavy metals contaminate natural bodies of water. At present, best management practices (BMP) intended to reduce the volume and treat pollutants from stormwater runoff were devised to serve as cost-effective measures of stormwater management. However, improper design and lack of proper maintenance can lead to degradation of the facility, making it unable to perform its intended function. This study evaluated an infiltration trench (IT) that went through a series of maintenance operations. 41 monitored rainfall events from 2009 to 2016 were used to evaluate the pollutant removal capabilities of the IT. Assessment of the water quality and hydrological data revealed that the inflow volume was the most relative factor affecting the unit pollutant loads (UPL) entering the facility. Seasonal variations also affected the pollutant removal capabilities of the IT. During the summer season, the increased rainfall depths and runoff volumes diminished the pollutant removal efficiency (RE) of the facility due to increased volumes that washed off larger pollutant loads and caused the IT to overflow. Moreover, the system also exhibited reduced pollutant RE for the winter season due to frozen media layers and chemical-related mechanisms impacted by the low winter temperature. Maintenance operations also posed considerable effects of the performance of the IT. During the first two years of operation, the IT exhibited a decrease in pollutant RE due to aging and lack of proper maintenance. However, some events also showed reduced pollutant RE succeeding the maintenance as a result of disturbed sediments that were not removed from the geotextile. Ultimately, the presented effects of maintenance operations in relation to the pollutant RE of the system may lead to the optimization of maintenance schedules and procedures for BMP of same structure.

Purpose: According to increment of thyroid cancer recently, patients of high dose radioiodine therapy were accumulated. Taking into consideration the acceptance capability in the current facility, this study is to calculate the maximum value of high dose radioiodine therapy in patients for treatment. Materials and Methods: The amount and radioactivity of waste water discharged from high dose radioiodine therapy in patients admitted at present hospital as well as the radiation density of the air released into the atmosphere from the high dose radioiodine therapy ward were measured. When the calculated waste water's radiation and its density in the released air satisfies the standard (management standard for discharge into water supply 30 Bq/L, management standard for release into air 3 $Bq/m^3$) set by the Ministry of Education, Science and Technology, the maximum value of treatable high dose radioiodine therapy in patients was calculated. Results: When we calculated in a conservative view, the average density of radiation of waste water discharged from treating high dose radioiodine therapy one patient was 8 MBq/L and after 117 days of diminution in the water-purifier tank, it was 29.5 Bq/L. Also, the average density of radiation of waste water discharged from treating high dose radioiodine therapy two patients was 16 MBq/L and after 70 days of diminution in the water-purifier tank, it was 29.7 Bq/L. Under the same conditions, the density of radiation released into air through RI Ventilation Filter from the radioiodine therapy ward was 0.38 $Bq/m^3$. Conclusion: The maximum value of high dose radioiodine therapy in patients that can be treated within the acceptance capability was calculated and applied to the current facility, and if double rooms are managed by improving the ward structure, it would be possible to reduce the accumulated treatment waiting period for radioiodine therapy in patients.

The aim of this study was to provide basic data in managing the project that was carried out on Bulgwangcheon in a nature-friendly way to improve the conditions around the areas, which was brought to completion in 2002, based on changes in ecological characteristics. For this propose, this study examined documents related to the project, compared physical and enviromnental changes before and after the project was conducted and analyzed changes in the stream ecosystem. The result showed that in areas that effluent water was often observed, especially when it rained, the river wall was washed away and vegetation was found damaged. As for actual vegetation, this study compared planting coverage of each section of the research area and actual vegetation charts. The results indicated that Lespedeza spp., Aster koraiensis among mixed seeds that were planted in the reservoir path were almost swept away while Festuca arundinacea dominated the areas. Phragmites communis, Miscanthus sacchariflorns and Salix gracilistyla which had been planted in a small number were also almost washed out though a small number of them were left to form a colony. After examining the topography and structure of the plant community, this study found that areas where mixed seed were planted had changed into two types of vegetation: First type of area is dominated by P and R which are usually raised in apron with abundant floating particles. The second type of area is dominated by dry gramineous plant such as F and A. Areas around low flow channel where Phragmites communis, Miscanthus sacchariflorus and Salix gracilistyla planting construction method is applied was washed away with the width of low flow channel reduced. Though P, M and S formed a small community in some areas around the low flow area, they were in small number and in composition of simple plant species. Two ways were suggested in this study to manage the stream in an ecological way. First, adequate revetment construction methods should be applied by monitoring the flow of the stream as well as considering the flood control of urban streams. Second, target vegetation communities that are suitable for the environment of the stream should be chosen and be plantedconstantly with high density. At the same time, ornamental native plants shouldn't be planted as they have been and disturbing vegetation should be removed.

A subsea tunnel, being a super-sized underground structure must ensure safety at the time of earthquake, as well as at ordinary times. At the time of earthquake, in particular, of a subsea tunnel, a variety of response behaviors are induced owing to relative rigidity to the surrounding ground, or difference of displacement, so that the behavior characteristics can be hardly anticipated. The investigation aims to understand the behavior characteristics switched by earthquake of an imaginary subsea tunnel which passes through a fault zone having different physical properties from those of the surrounding ground. In order to achieve the aim, dynamic response behaviors of a subsea tunnel which passes through a fault zone were observed by means of indoor experiments. For the sake of improved earthquake resistance, a shape of subsea tunnel to which flexible segments have been applied was considered. Afterward, it is believed that a D/B can be established through 3-dimensional earthquake resistance interpretation of various grounds, on the basis of verified results from the experiments and interpretations under various conditions. The present investigation performed 1 g shaking table test in order to verify the result of 3-dimensional earthquake resistance interpretation. A model considering the similitude (1:100) of a scale-down model test was manufactured, and tests for three (3) Cases were carried out. Incident seismic wave was introduced by artificial seismic wave having both long-period and short-period earthquake properties in the horizontal direction which is rectangular to the processing direction of the tunnel, so that a fault zone was modeled. For numerical analysis, elastic modulus of the fault zone was assumed 1/5 value of the modulus of individual grounds surround the tunnel, in order to simulate a fault zone. Resultantly, reduced acceleration was confirmed with increase of physical properties of the fault zone, and the result from the shaking table test showed the same tendency as the result from 3-dimensional interpretation.

This research focuses on 'dramaturgical' performance among all the acts of a director who constructs an artistic structure. This is, specifically, the dramaturgical acts that a director comes to perform in the process of dramatizing a novel. This paper aims to suggest a new kind of approach for productive interaction between drama theory and practice, not only by documenting the process of creation but also by moulding theoretical basis on acts of a director. As you all know, creative acts in practice so far have rarely been considered as subject and purpose of academic study. Even some lucky plays and directors had to settle for fragmentary review. That's mainly because Korean theatrical circles confine the way of recording the whole process of drama in practice only to a piecemeal review of performance. As a result, there have been very few cases of observing comtemporary plays under the historical background of drama. In this regard, this paper desires to raise a question, 'is productive interaction between drama theory and creative practice possible?' and to find the answer. If what is described in this paper can have worth beyond a mere record of creative acts, it may establish theoretical grounds on interpreting the play stage of this era by reading, in the contexts of drama history, a director's dramaturgical performing acts to dramatize a novel. The researcher of this paper, as a director of a theater troupe like a human and artistic community, adapted "Crime and Punishment" by Dostoevsky into four plays. They are , , , , and completed in 2009, 2011, 2012, and 2014, respectively as an independent theatric work having no connections to each other in story. Not only because the four plays share the same novel as its origin but also because an identical system is applied to dramatization of the novel, it gives an opportunity to focus on and perceive the role of the director. During the process of dramatiztion, the director, the researcher of this paper, carried all the duties, such as selecting a text, approaching the text theoretically and academically, adapting it for drama, picking out appropriate episodes. This paper defines all these acts as dramaturgical performing acts. In this sense, this paper can also be seen as a documentary of 'acts' performed during the process of dramatization.

In the estuary where the structure such as river-mouth weir has been installed, the flow is developed very complicatedly due to river water from upstream, tide of the sea and floodgate operation. Especially, if basin outlets more than one exists in one estuary, the boundary conditions will be significantly more complex form. Saemangeum(SMG) project area in Korea is the most typical example. There are Mankyung river and Dongjin river in upstream. The water of them inflows into SMG project area. In the downstream, river flow was drained from inland to sea over the SMG sea dike through the sluice. The connecting channel was located between Mankyung and Dongjin basins. It functions not only as transportation by ship in ordinary period but also as flood sharing by sending flood flow to each other in flood period. Therefore, in order to secure the safety against flood, it is very important to understand the flood sharing capacity for connecting channel. In this study, the flood control effect was analyzed using numerical simulation. Delft3D was used to numerical simulation and simulated period was set up with neap tide, in which the maximum flood stage occurred due to poor drainage. Actually, three connecting channels were designed in land use plan of the SMG Master Plan, but they were simplified to a single channel for conciseness of analysis in this study. According to the results of numerical analysis, the water level difference between two basins was increased and the maximum flood stage at dike sluice was also upraised depending on decrease of conveyance. And the velocity induced by same water level difference was decreased when the conveyance became smaller. In certain conveyance above, there was almost no flood control effect. Therefore, if the results of this study are considered for design of connecting channel, it will be expected to draw the optimal conveyance for minimizing dredging construction cost while maximizing the flood control effect.

This paper aims to identify the structural characteristics of Okawa Syumei(大川周明), Wakamiya Unosuke(若宮卯之助) and Okakura Tensin(岡倉天心). In fact, after Okawa Syumei studied the Principles of Wakamiya Unosuke and Okakura Tensin, he derived a conclusion and wrote a book named "yeolseongjeon". This book talks about the emperor dynasty. Based on this, the theory presented by Wakamiya Unosuke and Okakura Tensin described the characteristics of the East European culture. Okakura Tensin crossed the western part and discovered that western culture is only western culture and not a universal culture. Western culture has developed from its own experience. Wakamiya Unosuke translated a book by William Knox, The spirt of the orient. They have the same point of view, but they have a different culture and they must follow their own culture. Okakura Tensin insisted that culture is dynamic and it improves by adapting different cultures of different countries. Wakamiya appealed and he opposed Tensin's studies about culture. Wakamiya's definition of culture has not changed or is fixed from the past, which still exists in the modern times. Culture must be cultivated and it must be introduced to people who have forgotten their own culture. Despite such methodological differences, the commonality between Okakura and Wakamiya is that Western civilization is nothing more than a regional culture, as the West is not a universal civilization, but as a whole, it is a regional culture. Okawa Syumei learned the Okakura and Wakamiya's theory about culture and derived a conclusion. He stated that both opinions are correct as culture can be adapted as explained by Okakura. For example, Japanese people are now adapting and embracing the culture of Chinese people and Indian people. On the other hand, he also learned Wakamiya Unosuke's theory that culture does not change. Japanese have their own culture that was created in the past or it was developed by their ancestors; for example, the emperor dynasty. Okawa Syumei learned different cultures of different countries and Japanese people are adapting those cultures, and Wakamiya stated that the emperor dynasty must be instilled and it must be universal. Japanese emperors have different cultures, especially the Meiji emperor who is willing to accept different cultures of different countries. Finally, he claimed that the emperor dynasty created a new Japanese civilization and they are now embracing the new adapted culture.

Recidivism prediction has been a subject of constant research by experts since the early 1970s. But it has become more important as committed crimes by recidivist steadily increase. Especially, in the 1990s, after the US and Canada adopted the 'Recidivism Risk Assessment Report' as a decisive criterion during trial and parole screening, research on recidivism prediction became more active. And in the same period, empirical studies on 'Recidivism Factors' were started even at Korea. Even though most recidivism prediction studies have so far focused on factors of recidivism or the accuracy of recidivism prediction, it is important to minimize the prediction misclassification cost, because recidivism prediction has an asymmetric error cost structure. In general, the cost of misrecognizing people who do not cause recidivism to cause recidivism is lower than the cost of incorrectly classifying people who would cause recidivism. Because the former increases only the additional monitoring costs, while the latter increases the amount of social, and economic costs. Therefore, in this paper, we propose an XGBoost(eXtream Gradient Boosting; XGB) based recidivism prediction model considering asymmetric error cost. In the first step of the model, XGB, being recognized as high performance ensemble method in the field of data mining, was applied. And the results of XGB were compared with various prediction models such as LOGIT(logistic regression analysis), DT(decision trees), ANN(artificial neural networks), and SVM(support vector machines). In the next step, the threshold is optimized to minimize the total misclassification cost, which is the weighted average of FNE(False Negative Error) and FPE(False Positive Error). To verify the usefulness of the model, the model was applied to a real recidivism prediction dataset. As a result, it was confirmed that the XGB model not only showed better prediction accuracy than other prediction models but also reduced the cost of misclassification most effectively.
