In this paper, a new active noise control method was proposed to decrease a weight of car, and to increase a fuel efficiency and to provide passengers' comfort and calmness, instead of a passive noise control method such as sound absorbing and insulating materials. The proposed method is an enhanced active noise controller operating by a bidirectional control algorithm. The algorithm is simple to implement and available to analyze mathematically with nearly equivalent complexity of computation. Through simulations for engine noises of a car, the proposed controller was verified that its performances of time and frequency domain were superior to those of both feedforward and feedback controllers, and it had better capability of controlling the noises when the impulsive disturbance was flow in and the response of secondary path was varied.

This research explores the idea of digilog for fashion; it would help to conclude the uncertain mixed-phenomena and words as a neologism and find a fundamental concept that would be a reference for a lot of uncertain new words that have been occurring even this year. Furthermore, this research is aimed at analyzing how digilog has been reflected on the contemporary fashion and directing the ways towards the future of fashion. The digilog fashion design is the expression of a combination of opposite extremes, that is to say the combination of a paradoxical mix and directly-opposed elements. The outward expression of fashion design with digilog can be classified into several ways. First of all, it tends to use the elements of paradoxical expression; for example, applying high-technology to express a primitive and natural material. The analog expresses unprocessed. Secondly, using high-tech machine to express the texture of handicraft or rough embroidery. Lastly, digital printing(DTP) is applied to enlarge the several or the whole parts of a natural object or sensitivity. As a result of the analysis, the inside view of the contemporary fashion with digilog delineate followings; it is the attitude that claims to go back to the past and accepts the combination of nature and high-technology to get calmness in the rapidly changing modern world. And it is the will to fly from the utterly exhausted reality through the recurrence of the past when there used to be a lot of energies and used to live in affluence.

The purpose of this study was to examine and fully understand the transformation of female's ideal beauty through time based on word analysis. Word selection was made from the very exemplary Women's magazines : Yuhwon, Jubu-Saengwhal, and Yuhsung-Dongah. Further, in order to research the understanding of female's ideal beauty, a random research was done on 445 women, ranging from the ages 20's through 60's. From the result, a frequency analysis was performed to further analyze the meaning of ideal beauty to each sector of the age groups for different time periods : the 1980's and the 1990's. To the 20's, beauty awareness was defined by the word ‘intelligence’, however, the 1980's endorsed confidence with composure and calmness where as the 1990's preferred beauty to be defined by ‘refinement and goal oriented’. The 30's selected ‘individuality’ marked with confidence in character, but there was a shift from ‘mature intelligence’ in the 1980's to ‘professionalism’ in the 1990's. The 40'E chose mediocrity and commonness, however, likewise, a sense of ‘earnestness’ for life and family was looked upon as beautiful. For the 50's, comfort with a reserved tenure was frequently noted and for the 60's, women chose ‘health and independence’ as describing ideal beauty. The results from the research are justifiable because the articles are in a neutral perspective and are from the representative women's magazines. This research proved that the younger the age group, the more exterior beauty was considered, as opposed to the older generation who found inner beauty to be of most importance.

A breakwater is a important structure for both calmness of harbor and protection of the port facilities from waves generated from typhoons or wind. This study adopted the rubble mound breakwater, which is one of the most popular type of breakwaters in Korea. Rubble mound breakwater had been designed by considering only static condition previously. Recently, a dynamic wave-load due to waves has been also considered in designing breakwater. In design, the wave-load is assumed as an uniform load which only acts in the front slope of the breakwater. However, the assumption is not applicable in reality. In this study, therefore, a real-time wave-load acting on the breakwater instead of the uniform load is considered, and it is assumed to be acting on the seabed too. Based on the numerical analysis, it is found that there is a significant difference in the maximum settlement compared with the result predicted by the existing design method.

The current problems with the changing nature of the battlefield of the future point up the serious need for more and better research on the nature of effective military leadership. The purpose of this study was to examine effective leadership traits and behaviors of junior officers in combat situation. During times of peace, leader study battles and imagine themselves in all sorts of combat situations while at the same time, they must cope with numerous challenges and fill a variety of roles that they perceive are not battle related. This illustrates one of the fundamental paradoxes of the peacetime environment. Early studies, showing that combat leadership and noncombat leadership needed different talents, produced some clusters of traits which good combat leader were said to possess. Good combat leaders, for example, were described as possessing courage(e.g., bravery, fearlessness, daring, prowess, gallantry, guts, intrepidity, undaunted courage, fighting spirit, aggressive action), personal integrity(e.g., sincerity, flair, calmness, modesty), adaptability(e.g., flexibility, rapidity in action, speedy decision-making, clarity of thought) and so on. Behaviors found to be important in both combat and noncombat situations bore some relation to role requirements common to both situations. Behaviors important in one situation but not the other could be explained in terms of situational differences in role requirements for effective leadership. In order to achieve this purpose, a number of literature reviews were analysed. These results, though obtained in a somewhat rough and ready fashion, were useful not because they pointed to different leaders in war and in peace, but because they showed leaders the different things that were expected of them in different situations. It was also worth knowing how develop combat leadership. While these findings clearly suggest combat and noncombat differences, they do not necessarily confirm the complete study on effective leadership in combat situation. In conclusion, this study would be useful basis for further improvement on effective combat leadership and some further researches were recommended.

In this study, we tried to reveal the state of stillness of Cho Ji-Hoon's poem "Silent Night 1" as a healing modifier. The language of poem is synaptically linked to the calmness emotion of the human body, seeking a principle that leads to a state of healing. Therefore, this study was carried out for the purpose of applying the principle to literary therapy program. The silent signal embedded in the poem is encoded into the signals of the sound as it is synapsed to the human body. Encoding of auditory nerves by poem lines is like a Morse code that word and word leave in the human body. The action potential of the auditory nerve is further activated by the potential difference between the word and the word represented by the neural network, such as a Morse code, which is accessed to the human body by such a path. There is worked as amplified potential difference between the words perceived by a sound which is synapsed to the human body and by a silence which is synapsed to the human body. The phenomenon of the words approaching the human body and setting the absence of sound and amplifying the sound is because the words amplifies the Morse codes in the human neural network. At this time, the signals overlap each other. Thereby this poem is increasing the amplitude of the sound. This overlapping of auditory signals appears and amplifies the catharsis. If this Cho Ji-Hoon Poem's principle is applied to literary therapy program in the future, more effective treatment will be done.

In this paper, we propose a method of recognizing emotions using PPG sensor which measures blood flow according to emotion. From the existing PPG signal, we use a method of determining positive emotions and negative emotions in the frequency domain through PSD (Power Spectrum Density). Based on James R. Russell's two-dimensional prototype model, we classify emotions as joy, sadness, irritability, and calmness and examine their association with the magnitude of energy in the frequency domain. It is significant that this study used the same PPG sensor used in wearable devices to measure the top four kinds of emotions in the frequency domain through image experiments. Through the questionnaire, the accuracy, the immersion level according to the individual, the emotional change, and the biofeedback for the image were collected. The proposed method is expected to be various development such as commercial application service using PPG and mobile application prediction service by merging with context information of existing smart phone.
