This study was to understand "flow" that has been very popular in the area of phenomenology and to interpret it from the perspectives of mathematics education to activate its use in mathematics education. The flow is the state in which people are so involved in an activity that nothing else seems to matter; the experience itself is so enjoyable that people will do it for the sheer sake of doing it. If anyone in society can experience with training how to get into flow, students should have chances to experience flow included in high-order thinking in order to have better fuality of life and to be confident problem solvers in the future.

This study examines the possibility of development into a place of existential human meaning and the process of formation of placeness based on the Simulacre theory of digital game space. First of all, the game space related to humans was reinterpreted into the Simulacra theory of Plato, Jean Baudrillard, and Gilles Deleuze, and typified into three simulacra of spaces. The formation process of placeness in the game space is presented by linking the simulacra of space, place theory, and the user's game experience that were reinterpreted. It is hoped that this will contribute to exploring the aspect of the placeness of digital game spaces for authentic experiences of various media.

누수는 상수도시스템 내에서 발생할 수 있는 대표적인 비정상상황 중 하나이다. 누수는 발생 직후부터 경제적으로 직접적인 영향을 미치는 것과 함께 토사 내에서 유입되는 이물질 등으로 수질적인 문제 또한 발생할 수 있다. 이와 같은 이유로 누수는 발생에 대한 신속한 인지가 요구되며 이에 따른 신속한 복구가 필요하다. 하지만 기존의 데이터 기반 누수 탐사방법은 일반적으로 누수의 유무만을 인지하기 때문에 발생한 누수에 대한 규모의 정량적인 평가가 어려우며 이는 현재의 누수탐사 방법이 누수의 규모에 따른 복구 우선순위를 고려하기에는 부적절한 방법이라는 것을 의미한다. 따라서, 본 연구에서는 다중 누수시나리오 대해 누수 여부뿐만 아니라 누수 규모, 위치 등을 식별할 수 있는 수리해석 모델 기반 누수탐사 기법을 개발하였고, 이 기법을 활용하여 정량적인 누수량을 식별하여 누수 규모에 따른 누수복구 우선순위를 선정하는 프레임워크를 개발하였다. 이때, 누수복구 우선순위 선정 시 수리학적, 경제적, 사회적 인자 등을 고려하였으며, 각 인자 별 가중치를 통해 최종 복구 우선순위를 선정하였다.

This paper proposes a methodology applying sequence tagging methodology to improve the performance of NER(Named Entity Recognition) used in QA system. In order to retrieve the correct answers stored in the database, it is necessary to switch the user's query into a language of the database such as SQL(Structured Query Language). Then, the computer can recognize the language of the user. This is the process of identifying the class or data name contained in the database. The method of retrieving the words contained in the query in the existing database and recognizing the object does not identify the homophone and the word phrases because it does not consider the context of the user's query. If there are multiple search results, all of them are returned as a result, so there can be many interpretations on the query and the time complexity for the calculation becomes large. To overcome these, this study aims to solve this problem by reflecting the contextual meaning of the query using Bidirectional LSTM-CRF. Also we tried to solve the disadvantages of the neural network model which can't identify the untrained words by using ontology knowledge based feature. Experiments were conducted on the ontology knowledge base of music domain and the performance was evaluated. In order to accurately evaluate the performance of the L-Bidirectional LSTM-CRF proposed in this study, we experimented with converting the words included in the learned query into untrained words in order to test whether the words were included in the database but correctly identified the untrained words. As a result, it was possible to recognize objects considering the context and can recognize the untrained words without re-training the L-Bidirectional LSTM-CRF mode, and it is confirmed that the performance of the object recognition as a whole is improved.

The isotropic single-hardening constitutive model has been applied to predict the behavior of soils during reorientation of principal stresses in the field. The predicted response by the model agrees well with the measured behavior for a series of torsion shear tests performed on hollow cylinder specimens of Ko consoildated clay along various stress -paths. This indicates that the soil behavior during reorientation of principal stresses can be predicted by using the model with application of simple informations given by isotropic compression tests and conventional consolidated-undxained triaxial compression tests. Isotropic elasto-plastic soil behavior has been served during primary loading from both the torsion shear tests and the predictions by the model. However, the directions of maj or principal strain increment given by the model have not coincided with the directions for tests during stress reversal, such as unloading and reloading, within isotropic yield surface for Ko consolidated stress. This indicates that kinematic hardening model instead of isotropic hardening model should be developed to predict the soil behavior during stress reversal. The experimental strain increment vectors in the work-space have been compared with the directions expected for associated and nonassociated flow rules.

Open city information model can increase the understanding of the situation, enable the effective reuse of information due to access the semantic and relational conditions of objects, and support the reliable decision-making through linking with external references. The city information model focused on terrain and buildings was implemented based on the actual data. In addition, a process for flooding simulation was proposed using hydraulic analysis data and the city information model. The deaths and damages were estimated by flooding simulation. The availabilities were examined by detailed queries and responses based on model data of the city information model, hydraulic analysis data and the estimated damages.

The purpose of this study is to understand surrogate mother aged 20-30s by knowing meaning and structure of empirical phenomena. Methods is to applied to Phenomenological and heuristic Human Becoming Methodology, and the subjects of this study are four surrogate and host mothers who were on the air of SBS program, 'surrogate mother: having a baby for infertile couples(March 8, 2005)', and phenomenological and heuristic Human Becoming Methodology of Parse is applied in this study. Results is the structure that they chose surrogate mother as best option under the economic suffering, and pregnancy and bearing separated motherhood while facing unfair negotiating relationship and accepting reality of forgettable motherhood. The conceptual integration of relationship issues were: valuing, powering and transforming with the process of revealing-concealing and enabling-limiting. Finally, discussion and practical meaning was reviewed.

An empirical study and environmental and ecological analysis were conducted on Otgol Village(a village of the Gyeongju Choi's clan in Daegu) where an enclosed pond and groves are still observed. In particular, the enclosed pond and groves and village water system were investigated from an ecological perspective. The enclosed landscape is described based on feng shui principles and the environmental and ecological significance were examined. In general, the environmental and ecological significance is very broad; however, they were analyzed in terms of the quality of life as an empirical study as follows: First, water quality was measured to investigate the improvement of continuous water system functions. In other words, water quality was measured at East Valley(resting space), West Valley(living space), the enclosed pond where the two valleys merge, and the stream that flows out of the pond. Second, the climate functions of the enclosed groves that border the village were examined. In other words, temperature was measured in two places(200m distance from the center of the groves). Third, whether or not a sound ecosystem can be sustained was investigated. In other words, landscape ecological indicators were chosen and measured. The results are as follows: First, the enclosed pond played the role of purifying water quality. While the East Valley has been popular with men for its rock walls and torrents, the West Valley has been popular with women as a living space(ex: doing the laundry). Therefore, the difference of water quality can be explained. Second, since enclosed groves are in a small village forest, they are very weak in terms of being wind proof and temperature reduction effects. Instead, they play the role of the village boundary. Third, the groves are ecologically sound considering the landscape ecological indicators and are similar to ordinary traditional rural villages. In terms of the connection of the green zone, the village groves are well connected to the village boundary wood. If the village groves are restored, in particular, they would offer a decent habitat for grove creatures. According to this study, the traditional village space was formed upon the influence of Feng Shui theories that are based on environmental and ecological principles that focus on the harmony between humans and nature. From the environmental and ecological perspective, the enclosed pond and groves are important factors in building a sustainable village. The diverse water space would help to improve water quality and increase water volume by promoting the water circulation system. In addition, the village woods would surround the village and decrease the temperature and humidity difference between winter and summer. If the groves are small and badly damaged, however, they are meaningful only in dividing the region. The overall improvement of a forestation system and botanical composition may increase the biological diversity and promote the migration of species. Otgol Village has developed an enclosed landscape to improve the village environment. In other words, a sound and refreshing living environment can be developed when the natural ecological system is well understood and properly preserved. Additionally, this traditional village planning will be the environmental and ecological method. From the perspective of environmental ecology, therefore, a traditional village is recommended.

was released in South Korea in 2002 with more than 2million audiences and had been appraised as a successful and sensational work. The work let the audiences highly evoke interest and curiosity through offering magnificent sceneries, weird and funny creatures and stimulating imagination, before having no idea about the work producted by Miyajaki Hayao, one of the greatest directors. Well-concentrated his works seem to be easy to understand but have a variety of meanings in very different ways. Expending the range of analysis of his works, for example, from its technical to cultural and philosophical etc. has an enormous amount of value of diversity such as a ray of light passing through a prism. For this reason, has been studied in many different views. This paper will analyse this animation in respect of ideas of eastern as well as western to show differences from former papers. The ideas of eastern and western seem to be not in a line, but this study will suggest that the two different ideas are not different, actually. Through plural analysis of , ask questions about what life is and what the direction is.

In Korea, the soil series derived from sedimentary rocks are classified into seven soil series of coarse loamy soil such as Dain, Danbug, Dongam, Imdong, Jeomgog, Maryeong, and Yonggog; seventeen soil series of fine loamy soil such as Angye, Anmi, Banho, Bigog, Deoggog, Dogye, Dojeon, Gamgog, Gugog, Jincheon, Maji, Mungyeong, Oggye, Samam, Yanggog, Yeongwol, and Yulgog; six soil series of fine silty soil such as Goryeong, Bonggog, Juggog, Gyeongsan, Yuga, and Yugog; and four soil series of clayey soil such as Mitan, Pyeongan, Pyeongjeon, and Uji. All thirty-four soil series have different drainage rates and topography. However, the soil texture depends on the parent rock. The buffer functions in GIS (Geographic Information System) techniques were used to calculate adjacent soil series from a soil series. The length of the adjacent soil series was adjusted because a side of the buffer area was one meter long. The cluster analysis was conducted using the CCC (Cubic Clustering Criterion) method, in which the number of clusters is calculated based on the individual soil series ratio. Soil survey has been carried out since 1964 as "The reconnaissance soil survey", and 1:5,000 detailed soil survey was completed in 1999 with a five-years plan in Korea. Today, all the soil survey information has been computerized. GIS techniques were used to establish a digital soil map; however, there have not been any studies to interpret pedogenesis using the GIS technique. In this study, the area of the adjacent soil series were obtained using the GIS technique. The area of the adjacent soil series can be calculated based on the information area. The similarities of soil originated from sedimentary rocks were estimated using the length. As a result, the distribution of grain size was different based on the types of sedimentary rocks and the location. The clusters were distinguished into limestone, sandstone, and shale. In addition, the soil derived from shale was divided into red shale and gray shale. This means that quantitative interpretation of the catena and this established method can be used to interpret the relationship between soil series.
