Recently, web casting on the internet has been expanding in number and size. Web Casting is different from the conventional television broadcasting since it can transmit various types of information through multimedia and it also can include interaction between users and broadcasting server. User experience by interaction becomes more important. Therefore, it is needed to win over customers by supplying satisfied experience through creative and different services, especially when there are consider competitions among music casting sites. In order to know how to make customers satisfied, we have to try to inspect what real customers in the Web Sites are acting and thinking, namely 'customer experience'. The 'customer experience' means every experience what users are expecting, doing, thinking and feeling when they stay in the Web site and online. In this thesis, the evaluation Guideline for music casting websites is developed by understanding customer experience on the music casting websites. The process of understanding customer experience was implemented through user observation methods, such as web Diary, group interview, and questionnaire. As a result of the study, 67 evaluation Guidelines with weight rate in 6 categories which are searching music, listening music, music video, music broadcasting, music mailing and other contents are developed. It can be used to analyze strengths and weakness of music casting sites and to establish business strategy for the more satisfied customer experience.

Recently, deep learning encoder-based approach has been actively applied in the field of sentiment classification. However, Long Short-Term Memory network deep learning encoder, the commonly used architecture, lacks the quality of vector representation when the length of the documents is prolonged. In this study, for effective classification of the sentiment documents, we suggest the use of attention method-based deep learning encoder that generates document vector representation by weighted sum of the outputs of Long Short-Term Memory network based on importance. In addition, we propose methods to modify the attention method-based deep learning encoder to suit the sentiment classification field, which consist of a part that is to applied to window attention method and an attention weight adjustment part. In the window attention method part, the weights are obtained in the window units to effectively recognize feeling features that consist of more than one word. In the attention weight adjustment part, the learned weights are smoothened. Experimental results revealed that the performance of the proposed method outperformed Long Short-Term Memory network encoder, showing 89.67% in accuracy criteria.

The low frequency noise below 200 Hz, including inaudible infra-sound, is known to affect human physiology ; circulation, respiration, nerve, endocrine, etc. Legislation has been introduced in several countries regarding evaluation guideline and measurement method of low frequency noise. In this work, low frequency characteristics of the Seoul subway transportation system was investigated in terms of the noise level and spectrum in the interior of running passenger car and the subway station. The interior sound pressure level of the passenger car was between 60 and 105 dB in the frequency range of $1{\sim}200\;Hz$ and varied with car speed. The marked sound pressure level peak at 8 Hz, infra-sound, observed for the most of Lines is shown to correspond to the resonance frequency of passenger car. The level of station platform noise was lower than the interior noise of running car because of the lower speed at arriving/departure. The results indicated that the interior noise level of running passenger car was inside the oppressive feeling region, proposed by Ochiai, in the frequency range of $20{\sim}80\;Hz$ which makes a little concern.

The aim of this study was to provide fundamental information on the validity and credibility of the Korean geometric psychological assessment (GEOPIA) by investigating the degree of relation between the GEOPIA and the MBTI. Data was collected from 331 subjects aged 19 to 70, residing in Seoul, Gyeonggi Province, Jeolla Province, or Gyeongsang Province. Participants completed the GEOPIA and the MBTI during the period of May to September 2017. The study calculated Cronbach's ${\alpha}$ to verify the tests' validity and reliability through SPSS. For the relational analysis between the results of the tests, we conducted a one-way analysis of variance on the first group of the GEOPIA's personality types, and the Scheffe Test if significant relationship was found. The study found that the circle type was predisposed to ESFJ, the triangle type to ESTJ, the rectangle type to ISTJ, and S type to INFP. Higher scores of feeling (F) and perceiving (P) corresponded to circle and S types, thinking (T) and judging (J) for triangle and rectangle types, extroversion (E) for circle and triangle types, and introversion (I) for rectangle and S types. These confirmed the substantial relations between the GEOPIA and the MBTI.

This research analyzes the media which is simultaneously used with TV viewing, the behaviour of multiple media users, and the characteristics of TV programs under Nscreen circumstances. According to the results, TV provides stories and positions it as the main screen (84.5%, n=566), under the Nscreen circumstances. Personal media reproduces stories from TV by utilizing aspects of social media functions such as participation, open communication, community, connectivity, etc. The content is classified under three categories: 1) elicit emotion(point feeling), 2) information production, 3) participation, which is further divided into three subcategories; watch, wish, and result guarantee based on the level of interactivity. This inquiry is based upon diary survey and focus group interviews emphasized the role change of TV, specifically that TV takes a key role in generating original stories with the expansion of screen and social media. Even though users were able to watch the same TV programs at the same time and same place, the different methods of viewing: smartphone, tablet PC, web based mp3 and etc., it reproduced different stories and elicited different characteristics from its TV viewers.

At this time, the two main techniques for achieving web personalization assistant systems generally concern direct manipulation and software agents. While both direct manipulation and software agents are intended for permitting user to complete tasks rapidly, efficiently, and easily, their methodologies are different. The central debate involving these web personalization techniques originates from the amount of control that each allows to, or holds back from, the users. Direct manipulation can provide users with comprehensibel, predictable and controllable user interfaces that give them a feeling of accomplishnent and responsibility. On the other hand, the intelligent software components, the agents, can assist users with artificial intelligence by monitoring or retrieving personal histories or behaviors. In this empirical study, two web personalization assistant systems are evaluated. One of them, WebPersonalizer, is an agent based user personalization tool; the other, AntWorld, is a collaborative recommendation tool which provides direct manipulation interfaces. Through this empirical study, we have focused on two different paradigms as web personalization assistant systems : direct manipulation and software agents. Each approach has its own advantages and disadvantages. We also provide the experimental result that is worth referring for developers of electronic commerce system and suggest the methodologies for conveniently retrieving necessary information based on their personal needs.

Rapid industrialization has induced the migration of rural people to urban areas. Such migration has created enlarged the existing low income group. Residents of low income area have increased health risk owing to their poor living environment, low income. overwork and inappropriate health care. The general objective of this study was to group the pattern of medical care utilization of low income group. The specific objectives were to identify disease prevalence and medical care utilization of low income group. To meet the objectives of this study, household interview method was applied. A total of 1845 households in 5 areas such as Bongchon 5th Dong, Bongchon 2nd Dong, Sanggae 5th Dong, Sanggae 4th Dong, and Shinrim 7th Dong were visited and interviewed by field team during the period from April 19 to May 3. 1989. The major findings obtained from the information collected were as follows : The Number of room per household used was one to two rooms. The employment state of the head of household disclosed that 88.6% had a job and the remaining 11.4% were unemployed. The average monthly income was 502,770won. however, 30% of the total income was less than 300,000 won in Bongchon 5th dong area. and 34.5% in Shinrim 7th Dong area. 41.3% of households had debts, which was consisted of household expense(33.4%), income formulation(22.7%) and medical care cost(15.9%) etc. Prevalence rate of diseases during the preceding 30days before the date of the household interview was 387.7 per 1000 persons. The prevalence rate of female was higher than that of male. 8.9% of the sick persons wasn't receiving any medical treatment, and the main reasons of which were lack of economic availability(43.3%) and feeling of non treatment needed(33.7%). According to the study results it was found that the prevalence rate of chroic diseases and the disabled in low income resident areas was higher than that in the other areas. Therefore, the health status of this group should be improved through PHC approaches. In addition. in order to prevent the diseases and promote the health of those people, the health center as well as health subcenter should be strengthened.
