The purpose of this study is to present foundational data to promote the cultural welfare status of youth. The actual condition of the youth's cultural welfare was investigated by investigating the degree of youth's cultural welfare satisfaction and needs by regional groups. A total of 1486 questionnaires were used for the final data analysis. The analysis revealed the following results. 1. Actual conditions of adolescents cultural welfare. 1) Among various cultural activities, adolescents find leisure and social activity, artistic, mass media and video-media activities very boring and one-sided, Instead, they have greater interest in computer- and Internet-related activities, such as getting and sharing information and communication. 2) While adolescents living in urban areas benefit from well developed social infra-structure, those living in rural areas seldom take advantage of it. 3) The obstacles against cultural welfare of the youth can be categorized as: 'lack of money,' 'lack of time,' and 'lack of cultural facilities. ' In urban areas 'lack of time' becomes an issue, whereas in rural areas 'lack of money' and 'lack of cultual facilities' are important. 2. Degree of cultural welfare satisfaction of the youths. Youths generally appear either 'unsatisfied' or 'neutral' concerning their satisfaction degree about leisure and social activity parts, and art and play-activity paris. On the other hand, they appear 'neutral' concerning their satisfaction degree about computer- and Internet-related information and communication parts, and mass- and video-media activity parts. In addition, urban youths show a higher degree of satisfaction than rural youths. 3. What the youths need To improve their culture welfare status, they need a lot of supplements for cultural activity in the form of cultural infra-structure. Regarding the cultural infra-structure, rural youths need more than urban youths.

Products and/or services should be objectively verified in terms of the technological and use-conditional considerations before entering a market. Every organization or company tries to find the better procedure and method for checking the core needs of customers based on their experience in the market and looks for continuous ways to evaluate the power of products and services(PoP). They also prefer the overall evaluation of indices that could reflect various customer needs, rather than a separate evaluation index for each characteristic of the product or service. S. Ko (2008) proposes a Multi-characteristics Sigma Level(MSL) that can simultaneously evaluate many characteristics of a product or service. In this research, using MSL and a new Blue Ocean Index(BOI), an application of NPS, mobile phone field test is considered from a practical and statistical point of view.

Interpolation or super-resolution is used in order to restore degradation of image quality that appears after various transform of image. The method on subjective or objective image resolution improvement having low computation complexity has been being researched in many different ways. In this paper, image enhancement method using improved self degradation restoration(ISDR) method is proposed. The proposed method uses ISDR to estimate pixel value of missed coordinate in the process of image scaling, and combines the estimated loss information and interpolated image to generate enhanced result image. The proposed method shows that PSNR increases by 1.8dB, and subjective image quality is superior to other compared methods. The proposed method can be applied as a basis technique in variety of applications which requires image scale transform.

Based on the topographical and vegetational indicators on sediment movement of Yongcheon River, the movement occurence years were estimated. 1. The cross sectional shapes of deposits in torrential stream are stepped and even-aged forests tend to be established on each step. 2. Generally the older the forest age is, the higher the height of step from the lowest base tend to become. 3. The ages of trees indicate the year when deposition occured, and so may be useful as plant indicator to get chronological information.

If an infant with congenital hearing loss is diagnosed in good time and get proper treatment as soon as possible, treatment effect could be maximized and the social costs could be considerably reduced. For these reasons, the medical equipment to screen hearing impairment objectively is needed. The ABR(auditory brainstem response) is typical diagnostic tools for this purpose but there are drawbacks in sense that it does not have frequency specificity and shows hearing information of usually high frequency band. The ASSR(auditory steady-state response) is excellent in frequency specificity, but the rate of wrong diagnosis is slightly high. In this study, we proposed the system which can measure both the ABR and the ASSR, and can show the objective and quantitative indices(Fsp and F-test). It was designed to allow various tests without hardware modification by minimizing hardware components and by increasing software roles. The objective assessment of the developed system was evaluated by experiments with 10 normal persons.

최근의 많은 연구에서 정보기술에 대한 서비스제공 및 서비스 질(qualiy)에 대한 평가와 측정도구의 개발이 활발하게 이르어져 왔다(Pitt et al 1998) 또한 서비스 주체가 인적 요인에서 무형의 매체로 전환되고 있으며, 이러한 원인은 정보기술의 응용성에서 찾을 수 있다. 따라서 본 연구에서는 기존의 서비스 관점을 정보기술의 응용분야의 한 핵심이 될 수 있는 정보통신분야의 이동 휴대통신을 중심으로 서비스 질을 평가하여 문제점과 대안을 탐색하고자 하였다. 정보통신분야는 기간산업으로서의 역할과 그 중요성이 더욱 증대되고 있으며, 개별 기업차원에서도 정보기술 인프라는 중요한 경쟁요인이 될 수 있다. 그러나 이 분야에 대한 연구가 미흡하고 단순한 지표를 통한 비교 등의 연구 방법론에 있어서도 미비하다고 볼 수 있다. 따라서 본 연구에서는 정보통신분야의 중요성을 인식하고 초기 단계의 이동 휴대통신 분야의 핵심역량을 규명하고 향후 서비스 전략의 성공요인을 찾아내고자 하였다. 이러한 연구를 수행하기 위해 서비스만족 변수를 대리 측정도구로 이용하여 정보통신 기술 부분, 정보제공 부분, 비용우위 및 차별화 부분을 통해 계층적으로 접근하였다. 본 연구의 결과는 크게 세부분으로 요약된다. 첫째, 정보통신기술 부분에 대해 혁신적이고 안정적일 때 서비스만족도는 우수한 것으로 분석되었다. 또한 통신장비 및 부가장비의 우수성도 서비스부분에 미치는 영향력이 큰 것으로 나타났다. 둘째, 정보제공과 서비스만족과의 관계에서는 필요정보에 대한 서비스 밀착도가 높으면 서비스만족도는 높은 것으로 분석되었다. 또한 정보제공 분야의 서비스 개발력은 서비스만족도에 미치는 영향정도도 크게 작용하는 것으로 나타났다. 셋째, 차별화 및 비용우위와 서비스만족과의 관계도 매우 유의한 것으로 분석되었다. 특히, 비용 및 요금은 서비스만족도에 결정적 영향변수로 나타났으며, 광고 및 홍보부분도 만족도의 영향변수로 분석되었다. 이러한 연구결과는 향후 서비스전략에 응용될 수 있으며, 이동 휴대통신분야의 성공요인을 가시적으로 분석할 수 있다. 본 연구의 한계점은 첫째, 실제 서비스를 제공하는 서비스 주체의 객관적인 평가가 부족하였고 이러한 상횡에서 정보통신 기술 서비스 능력이 잘 반영되지 못했다는 점을 들 수 있다. 둘째, 이동 통신의 분야별 연구를 통해 비교 평가가 세부적으로 이루어지지 못했으며 연구방법상 샘플조사의 한계와 객관적인 응답자료를 확보하기가 어려웠던 점을 들 수 있다. 마지막으로 분석결과에서는 변수간의 유의성이 있는 것으로 볼 수 있지만 측정도구가 미약하며, 향후 지속적인 연구와 측정도구의 개발이 필요하다고 볼 수 있다.

Construction industry is based on receiving an order. So, it has a special feature that market and manufacture activity is formed by a user. For this reason, it has a great influence on other industry compare construction industry with other industry. Specially when build public structure as infrastructure, importance of owner is emphasized then private construction because the primary role of owner have a great effect on national finance. Inspite of that, the importance of a faculty and role of an owner and an ordering organ, it is weak that a study about objective and meaningful evaluation of the specially, common standard and ability of public ordering organ as a major user of domestic construction industry. So, this study define the evaluation sphere and an element of an ordering ability for develop an ordering ability evaluation guide which can evaluate objective ability of an ordering organ. Apply its evaluation sphere and element, judge a standard of an owner, thought the judgement, it can judge accurately of short ability and if it can make future oriented strategy, it can elevate the efficiency of an owner organization management.

The goal of the present paper is to objectify the intrinsic subjectivity of sound as a media of music by applying psycho-acoustical methodology to the analysis of a musical work. First, 18 sound samples are extracted from "Symponie Fantastique" written by Hector Berlioz, which is a piece of program music, and then the objective Zwicher's sound quality parameters such as: Loudness, Sharpness, Roughness and Fluctuation Strength are evaluated for each of these sound samples. For subjective sound quality evaluation, 9 representative sound quality adjectives are extracted on a basis of program feature of Symponie Fantastique and the first jury test is carried out by using the numeric rating method and the paired comparison method. Three sound quality adjectives, "bright", "noisy", and "realistic" are extracted from the factor analysis of the first jury test result. On a basis of the computed sound metrics and the second jury test result for the three sound quality adjectives, three sound quality indexes are developed to represent the sound qualities of "Symponie Fantastique".

In the modern society, as development innovative technology consumers could access various information. It make consumers empower in the market, and information asymmetry problem were solving more and more. In the technical information, however, there are still information asymmetry because technical information is very difficult to understand, and those are related with professional knowledge such as financial information. This study used the dataset which was collected to track Korean consumers consumption index by KCA(Korea Consumer Agency) which included consumer's problem experience at financial field. The results are followings. Firstly, consumers want to get exact and important information to decide purchase or not and comparative information in technical information area. Secondly, age is the influence variable to experience more problems in technical information section. Thirdly, consumer's subjective financial competency is major influence factor to reduce problem experience.
