Through Korean traditional opera (changgeuk) Medea, composer Hwang Ho-jun showed eclectic music idiom by 1) writing music (jakchang) on manuscript paper and score, 2) introducing the "song-through" format, 3) including various solo melodies, 4) maximizing the effect created by a singing narrator (dochang) with the chorus master and a mixed chorus, 5) seeking an interplay of tension and release by using both discord and chord, 6) achieving the effect of kil-bakkum, the Korean traditional method of modulation, through modulation and borrowed chord of Western music. In Medea, instrumentalists adopted suseong-banju (Korean traditional accompaniment) which does not spoil the voice of singers. Hwang adopted song for the way how singers express various hidden sides of play among song, aniri (narration) and balim (gesture) and introduced the Sung-through format in which the play is comprised entirely of song. In Medea, oral sounds expressing wail, lament, cheer, sneer and scream are often used and various solo melodies appear that fit for personalities of characters, clearly showing what bunchang (singers' singing songs divided according to characters) is all about. And discord and chord are effectively used according to the development and mood of play. Hwang also achieved successfully the effect of kil-bakkum by abandoning the traditional modulation method and boldly introducing modulation and borrowed chord of Western music.

This study is to present a draft for the formulation of uniform title for sound recordings of the Korean traditional music. The draft as the results of this study is summarized as follows: In a musical work of a type of non-composition, the popular name is put into square brackets as a uniform title of court music and folk music in the old Korean traditional music, and the composer's original title is put into square brackets as a uniform title of the new Korean traditional music, but the medium of performance and others are omitted except an identifying element. However, for the formulation of uniform title of a type of composition in an instrumental music, the descriptive form consisted of the order of 'name of one type of composition, medium of performance, serial number, opus number, key, and a descriptive word or phrase' is put into square brackets as a uniform title and the identifying elements. And in the vocal music of the old Korean traditional music, the following medium of performance is used: in vocal choruses, a type of voices; in solo voices, a type of solo voice by sex, but one of the new Korean traditional music follows the descriptive form of the western classical music.

Purpose : The purpose of this study is to check the current status of accessability to rehabilitation therapy in local areas and to review how to improve the accessability. In fact, first, it is very hard for patients to find out a local medical center with rehabilitation therapy capability. Moreover they needs to wait long time to get a treatment they need, because of lack of nearby rehabilitation centers. The best way to enhance the accessability to the rehabilitation therapy service is to allow therapists to set up rehabilitation centers in local areas on their own, physically independent from medical doctors. Basically, the current law does not prohibit therapists' own sole practice. However, it needs to be amended by inserting an explicit legal basis on the setting-up process. If it is legally permissible for the therapists to set up rehabilitation centers to perform a rehabilitation treatment with referrals from of medical doctors (though physically independent from the doctors), it would result in the increase of profits for the doctors and at the same time raise therapists' freedom of occupation, a constitutional right. Furthermore, with their own places to practice, therapists will have to compete with other therapists, that would raise the quality of their treatments, which will in turn benefit patients ultimately. A proposed bill of amendments to the Act on Medical Technicians and etc. is pending for review at the National Assembly. I look forward to vigorous discussion on the bill based on this article, and resulting in revision of the law for the benefits of patients.

Stirling engine for solar thermal power is an essential part of Dish-Stirling system which generates electricity by using direct normal irradiation and will go into commercialization in near future. For the Stirling engine used in this study is Solo 161 model the capacity of which is 10 kWe and was already used for the Dish-Stirling system of KIER in Jinhae. The receiver of Stirling engine absorbes concentrated solar radiation and transfer it to working fluid of Hydrogen. The working condition of striling engine is high temperature and high pressure to make high efficiency. Therefore the receiver should stand against high temperature of above 800 $^{\circ}C$ and high pressure of max. 150 bar with good performance of heat transfer. The receiver is composed of 78 Inconel tubes of 1/8" with thickness of 0.71 mm and two reserviors which is connected with two cylinders. In order to know the charaterristics of heat transfer of Stirling engine receiver, simulation on the heat transfer of the receiver of Solo 161 is conducted by using CFD code of Fluent. The heat flux on the receiver surface has a shape of Gaussian distribution so, it is necessary to simulate a whole receiver. However, It is difficult and time consuming to simulate the whole receiver that one tube with different heat flux conditions are considered in this study. From the simulation results, heat transfer charateristics of receiver are observed and tube wall and fluid temperature and heat transfer coefficient are obtained and compared with the calculated results from Dittus-Boelter's correlation.

This study investigated that the preference model of soloist performers for both vocal and instrumental types in terms of a stage support parameter, ST1. The test was carried out on a stage of a fan-shaped multi-purpose hall with orchestra shell. Objective measurements were carried out at 15 positions on the stage to evaluate various stage condition. The results showed that ST1 varies between -19.9 and -11.3 dB. Vocal and instrumental players participated in performance evaluation test as they played at 5 selected positions according to ST1 values. Players' preference was evaluated by 5-point rating and rank ordering method. As a result, it was found that the preference model of vocalist is different from that of instrumentalist. It was also found that the ST1 does not correlate well with the performer's preference.

In this paper, we present a vocal suppression algorithm that can enhance the quality of music signal coded using Spatial Audio Object Coding (SAOC) in Karaoke mode. The residual vocal component in the coded music signal is estimated by using a cross prediction method in which the music signal coded in Karaoke mode is used as the primary input and the vocal signal coded in Solo mode is used as a reference. However, the signals are extracted from the same downmix signal and highly correlated, so that the music signal can be severely damaged by the cross prediction. To prevent this, a psycho-acoustic disturbance rule is proposed, in which the level of disturbance to the reference input of the cross prediction filter is adapted according to the auditory masking property. Objective and subjective test were performed and the results confirm that the proposed algorithm offers improved quality.

The purpose of this research is that to study of musical performer's purchasing behavior, satisfaction and design preference, and to give the information for better performance costume market based on that result. The target for the survey is limited only for above 4th grade female students and have experienced more than three times of performances. Total 364 questionnaires are used for this research. The SPSS was used for the analysis. The results were, first, in the survey of place of purchasing, specialty shop for musical performance shop was the most. The most group for the budget that they spent was under 100,000 Won. Rational price for costume would be 150,000-300,000 Won. Most people purchase costume before 2 weeks and compare 3-4 stores mostly. There were not many complaints about being comfort for costume itself. The preference for costume was different depends on not only scale of performance but also whether solo, duet or trio or more. Also harmony with other person costume was most consideration factor when they perform duet or more. For the choice of shop factor following were considered the most important; various selections, kindness of sales persons and possibility for trying various costumes. However, locations of shop or delivery service were not important relatively. For the choice of costume factor, design color, comfort and functionality were considered the most important but price, quality and decoration were not. For 'the satisfaction after purchase costume' factor, people's opinions, best appearance on the stage and meeting image with themselves were considered the most important. Second, on the subject for 'design preference of costume based on type of performance', people chose different color of dress depends on what types of performance. In case of solo, they prefer vivid primary color; in case of trio or more, they prefer black; in case of duet, they prefer pastel tone. As for preference of sleeve design, all of them prefer non-sleeve type.

Student pilots receiving flight education are inexperienced in piloting and situation judgment skills and are greatly affected by various factors such as psychological, physical, and environmental factors. In particular, one of the most influential factors in the flight education of student pilots is the weather conditions. Unlike large aircraft used in the air transportation business, small aircraft used for flight education have a great impact on education, such as flight restrictions depending on weather conditions, psychological pressure in severe weather, and deterioration of student skills. Therefore, in this study, the meteorological characteristics of meteorological factors that have a great influence on small aircraft were analyzed. As a result of the analysis, an efficient and safe training operation method was suggested to a professional pilot aviation training organization through the adjustment of the training period for the season, the increase in aircraft operation rate, and a safe solo flight plan considering the weather.

Claude Debussy's is a solo piano piece written in 1894. However, for unknown reasons, the entire piece was not published until 1977, despite clear evidence that Debussy intended to publish it during his lifetime. Interestingly, the second movement of the three pieces comprised in the work was published independently in February 1896 through the Parisian periodical Le Grand Journal. Partly because the work was recently published, it remains relatively more unknown to pianists and music lovers than other piano solo pieces by Debussy. Thus, this article addresses in detail the compositional background of this work, focusing on why the work was not published during Debussy's lifetime. Furthermore, by analyzing this piece in detail, this article intends to discuss the stylistic characteristics of the work regarding its melody, phrase structure, harmony, and form. This survey, which would help understand the musical style embodied in this piece, aims to contribute to improving the awareness of the work.

In Korean traditional music, the frequency of Hwang-Jong tone is not known precisely, to say nothing of the temperament. So we measured the frequency of Hwang-Jong tone in solo pieces for the woodwind instruments such as daegum, piri and danso. According to the results of the measurement, the frequency of Hwang-Jong tone is about 328Hz, which is closer to the frequency of E$_3$(330Hz) than that of E$^b_3$(311Hz). This result is different from the existing theory that the frequency of Hwang-Jong tone is close to that of E$^b_3$.
