  • Organic light-emitting diodes (OLED) as pixels for flat panel displays are being actively pursued because of their relatively simple structure, high brightness, and self-emitting nature [1, 2]. The top-emitting diode structure is preferred because of their geometrical advantage allowing high pixel resolution [3]. To enhance the performance of TOLEDs, it is important to deposit transparent top cathode films, such as transparent conducting oxides (TCOs), which have high transparency as well as low resistance. In this work, we report on investigation of the characteristics of an indium tin oxide (ITO) cathode electrode, which was deposited on organic films by using a radio-frequency magnetron sputtering method, for use in top-emitting organic light emitting diodes (TOLED). The cathode electrode composed of a very thin layer of Mg-Ag and an overlaying ITO film. The Mg-Ag reduces the contact resistivity and plasma damage to the underlying organic layer during the ITO sputtering process. Transfer length method (TLM) patterns were defined by the standard shadow mask for measuring specific contact resistances. The spacing between the TLM pads varied from 30 to $75\;{\mu}m$. The electrical properties of ITO as a function of the deposition and annealing conditions were investigated. The surface roughness as a function of the plasma conditions was determined by Atomic Force Microscopes (AFM).

  • Device-to-Device (D2D) communication is a technology component for long-term evolution-advanced (LTE-A). In D2D communication, users in close proximity to each other can communicate directly without going through a base station; such direct communication can improve spectral efficiency. Although D2D communication brings improvement in spectral efficiency, it also causes interference to the cellular network as a result of spectrum sharing. In particularly, D2D communication can generate interference for each D2D pair when the common wireless medium in a co-located limited area is accessed. Even though the interference management for between the D2D pair and cellular networks has been proposed, the interference reducing methods have still not been fully studied for the D2D pairs. In this paper, we investigate the problem of D2D pair coexistence in which interference is considered between D2D pairs. Using a signal to interference model for a target D2D pair, we provide an analysis of the aggregated throughput of a dense D2D network. For a target D2D pair, we assume that the desired signal and interference signals obey multipath fading and shadow fading. Through analysis, we demonstrate the effect of cluster size such as the number of D2D pairs and the size of the considered area on the network performance. The analytical results are compared with computer simulations. Our work can be used for a rough guideline for controlling the system throughput in a dense D2D network environment.

  • In Christopher Marlowe's Cambridge days in the 1580s, the British forward wits were engaged in the curious pursuit of magic and occult philosophy in order to discover the mystery of things. Magic, together with judiciary astronomy, astrology, mathematics, and logic, was one of the most practical disciplines. Marlowe, Shakespeare, and Jonson demonstrate their deep interest in magic and its language of spell and charms in the light of their analogical application to the alchemical theatre. As Shakespeare says that the poet, the lover, and the madman are of the same because they give forms to airy nothing, a magical illusion is, for the three playwrights, similar to the theatrical illusion in that both magic and theatre work in and by a language and both give us sportive pleasures through the deceptio visus. However, while Jonson is rather puritanically antagonistic to the illusive language of alchemy and magic, Marlowe and Shakespeare are attracted to the rapturous nature of the absolute language of magic. Doctor Faustus' indulgence in magic stands for the Marlovian aspiration for the absolute language which allows no discrepancy between thinking and willing, conceiving and actualizing. His uses of spells, charms, anagrams, and magic books are transformed and translated in the play into an alchemical theatre. Faustus is dependant on and bound by his books of magic, as is the actor on the stage. Faustus is the poet condemned from the beginning. Though he is mistakenly thinking that it is he himself that manipulates Mephostophilis the magical agent, it is otherwise. Faustus is a shadow or an actor in the Elizabethan language. He remains a farcical figure during the twenty-four years which are given to him for his sensual dalliance. Marlowe never forgets through his farcical clowning to satirize such Catholic rituals as exorcism and benediction for their illusive theatricalism. The sports of Faustus' playacting and play-directing rise at the last hour to the height of a tragedy. Ironically Marlowe the playwright succeeds as a tragedian at the point where Faustus fails as a magician.

  • Music keeps significant influences on human mind. According to the analytical psychology, music affects the consciousness, and unconsciousness (both personal and collective). Structurally speaking, music affects the ego, shadow and self. Based on these findings, the author reviewed the life and work of Beethoven and Jung and investigated the following issues : 1) What were the developmental processes of them? 2) How did the educational processes affect their works? 3) What were the basic attitudes regarding interpersonal relationship and others? 4) What were the final psychological, social and spiritual achievements of them? Beethoven and Jung had psychologically and socially hard times during their developmental processes. However, they could achieve mature development in overcoming their difficulties. Both of them were effortful and serious book readers which could help them get wide range of perspectives on human existence and let them introspect deeply into their mind. They both could achieve the 'Concept of Gegensatzvereinigung'- that is the 'integration of two contrasting concepts into one wholeness'-. And this concept can be applied in the practical clinical settings for individuation. If psychiatrists could cease the discrimination between them and patients, they will be able to overcome subjective discrimination and prejudice against patients and accomplish objective truth. Finally they could integrate life and death into complexio oppositorum. In doing this, they have achieved eternal life.

  • The field of geospatial information is rapidly changing due to the development of sensor and data processing technology that can acquire location information. And demand is increasing in various related industries and social activities. The construction and utilization of three dimensional geospatial information that is easy to understand and easy to understand can be an essential element to improve the quality and reliability of related services. In recent years, 3D laser scanners are widely used as 3D geospatial information construction technology. However, 3D laser scanners may cause shadow areas where data acquisition is not possible when objects are large in size or complex in shape. In this study, 3D model of an object has been created by acquiring oblique images using an unmanned aerial vehicle and processing the data. The study area was selected, oblique images were acquired using an unmanned aerial vehicle, and point cloud type 3D model with 0.02 m spacing was created through data processing. The accuracy of the 3D model was 0.19m and the average was 0.11m. In the future, if accuracy is evaluated according to shooting and data processing methods, and 3D model construction and accuracy evaluation and analysis according to camera types are performed, the accuracy of the 3D model will be improved. In the point cloud type 3D model, Cross section generation, drawing of objects, and so on, it is possible to improve work efficiency of spatial information service and related work.

  • is a work of art that was composed through fluid and laminating by being passed down orally for a long time like other ancient songs. As well as, it is given a history of literature's value in the point that it is a Korea's first poetry work, it is considered it casts a long shadow to establishing traditionality of our country's poetry. Even today, has been transformed and recreated into a variety of genres because its literary subject carry the universal emotions and win the sympathy. This manuscript examines modern poetry, modern novel and modern songs that consist of changed ancient song and looks modern writers' perspective about through characteristic that each of works has and then aims checking special situation and meaning that is implicit and recognizing the value of the original. As the has been recreated as modern poetry, it shows the current chaotic situation specifically by embodying it and actively seeks expressing human character, agony and longing, etc, by excluding factor of the original mythical interpretation. Also it rouses situation of reality as detained and repressed. , recreated as modern novel, expands narrative structure and shows portrait of various characters and speaks diverse human condition about reality and suggests plan for dealing with that. Basic emotions of the original is strongly passed to modern popular song . It makes us know that universal emotions which human has across generations can touch people transcending time and space and it is a fresh discovery and possibility that reaffirms the emotion of our people. Ancient song has been studied with emphasis on resignation and grief by focusing on the subject, simply parting and death. But recently, through transformation between a wide range of genres. it carries the spirit of the times that author toward, showing realistic and specific situations. Flexibility of ancient song is expected to continue its vitality transcending generations. Ancient song is assured that it can lead various aspects through active groping in era of change with a various possibility, that the original has, through communication between genres.

  • North Korea's continuous threats and provocative behaviors have aggravated tension on the Korean peninsula particularly with the recent nuclear weapons test. South Korea's best way to cope with this situation is to maintain the balance among three policy directions: dialogue, sanctions, and deterrence. Among the three, I argue that deterrence should be prioritized. There are different sources of deterrence such as military power, economic power, and diplomatic clouts. States can build deterrence capability independently. Alternatively, they may do so through relations with other states including alliances, bilateral relations, or multilateral relations in the international community. What South Korea needs most urgently is to maintain deterrence against North Korea's local provocations through the enhancement of independent military capability particularly by addressing the asymmetric vulnerability between militaries of the South and the North. Most of all, the South Korean government should recognize the seriousness of the negative consequences that North Korea's 'Nuclear shadow strategy' would bring about for the inter-Korea relations and security situations in Northeast Asia. Based on this understanding, it should develop an 'assertive deterrence strategy' that emphasizes 'multi-purpose, multi-stage, and tailored deterrence whose main idea lies in punitive retaliation.' This deterrence strategy requires a flexible targeting policy and a variety of retaliatory measures capable of taking out all targets in North Korea. At the same time, the force structures of the army, the air force, and the navy should be improved in a way that maximizes their deterrence capability. For example, the army should work on expanding the guided missile command and the special forces command and reforming the reserve forces. The navy and the air force should increase striking capabilities including air-to-ground, ship-to-ground, and submarine-to-ground strikes to a great extent. The marine corps can enhance its deterrence capability by changing the force structure from the stationary defense-oriented one that would have to suffer some degree of troop attrition at the early stage of hostilities to the one that focuses on 'counteroffensive landing operations.' The government should continue efforts for defense reform in order to obtain these capabilities while building the 'Korean-style triad system' that consists of advanced air, ground, and surface/ subsurface weapon systems. Besides these measures, South Korea should start to acquire a minimum level of nuclear potential within the legal boundary that the international law defines. For this, South Korea should withdraw from the Nuclear Non-proliferation Treaty. Moreover, it should obtain the right to process and enrich uranium through changing the U.S.-South Korea nuclear cooperation treaty. Whether or not we should be armed with nuclear weapons should not be understood in terms of "all or nothing." We should consider an 'in-between' option as the Japanese case proves. With regard to the wartime OPCON transition, we need to re-consider the timing of the transition as an effort to demonstrate the costliness of North Korea's provocative behaviors. If impossible, South Korea should take measures to make the Strategic Alliance 2015 serve as a persisting deterrence system against North Korea. As the last point, all the following governments of South Korea should keep in mind that continuing reconciliatory efforts should always be pursued along with other security policies toward North Korea.

  • The aim of this study was to enhance the safety and care of mental health for seafarer working in passenger ship workspaces. Brightness, color values, and color distribution were investigated with issues and improvement ways identified through seafarers' interviews. Firstly, previous studies, references, current policy, regulations, and accident case studies were reviewed. Color compositions of wheelhouse and engine room of M Ship were then surveyed in the field. Color values of each space were analyzed using a colorimeter. Colormeter analysis of brightness and color measurements in the wheelhouse and engine areas indicated that ceilings, walls, and floors were generally dark, with the engine area being very dark. Regarding color, green and blue were distributed in the ceiling of the wheelhouse and engine area, while red and blue were in the walls and floors of the wheelhouse and engine area. According to interviews with seafarers currently working at engine rooms, they responded about their experience of near miss incidents due to a decrepit indoor environment, a dark working environment, slippery and bright flooring, and stairs that were not suitable for domestic users. Thus, when installing lighting in the future, the brightness of the space should be improved by distinguishing between night and day. A lighting plan considering the location of lighting, level of shadow formation and contrast, reflectance of the facility, glare, color of light, floor color plan, and material selection is needed. A facility design suitable for domestic users is also needed.

  • As the number of available satellites increases and technology advances, image information outputs are becoming increasingly diverse and a large amount of data is accumulating. In this study, we propose a change detection method for high-resolution satellite images that uses transfer learning and a deep learning network to overcome the limit caused by insufficient training data via the use of pre-trained information. The deep learning network used in this study comprises convolutional layers to extract the spatial and spectral information and convolutional long-short term memory layers to analyze the time series information. To use the learned information, the two initial convolutional layers of the change detection network are designed to use learned values from 40,000 patches of the ISPRS (International Society for Photogrammertry and Remote Sensing) dataset as initial values. In addition, 2D (2-Dimensional) and 3D (3-dimensional) kernels were used to find the optimized structure for the high-resolution satellite images. The experimental results for the KOMPSAT-3A (KOrean Multi-Purpose SATllite-3A) satellite images show that this change detection method can effectively extract changed/unchanged pixels but is less sensitive to changes due to shadow and relief displacements. In addition, the change detection accuracy of two sites was improved by using 3D kernels. This is because a 3D kernel can consider not only the spatial information but also the spectral information. This study indicates that we can effectively detect changes in high-resolution satellite images using the constructed image information and deep learning network. In future work, a pre-trained change detection network will be applied to newly obtained images to extend the scope of the application.
