본 논문에서는 이산 은닉 마코프 모델(Discrete Hidden Markov Model)을 이용한 연결 음성 인식에 관한 알고리듬 및 모델 토폴로지를 제안한다. 제안된 모델은 인식률과 인식할 수 있는 어휘를 고려하여 2 음소열 및 3 음소열 모델을 사용하며, 보다 정확한 음소 간의 세그멘테이션과 알고리듬의 수행 속도를 고려하여 2 음소열에서는 첫 번째 상태와 마지막 상태를 안정 상태, 나머지 상태는 천이 상태인 4 개의 상태를 갖도록 하고, 또한 3 음소열에서는 7 개의 상태를 갖도록 하며, 여기서 7개의 상태는 3 개의 안정 상태와 4개의 천이 상태를 갖도록 개선한다. 또한, 제안된 음성 인식 알고리듬은 인식 과정 내에서 음소의 발음 구간을 검출하도록 설계한다. This paper proposes an algorithm and a model topology for the connected speech recognition using Discrete Hidden Markov Models. A proposed model uses diphone and triphone model which consider the recognition rate and recognisable vocabulary. Considering more exact inter- phoneme segmentation and execution speed of algorithm, 4 states have to exist in diphone model where the first state and the last state are keeping a steady state, the other states hold a transient state. 7 states have to exist in triphone model where 7 states are specified and improved to 3 steady states and 4 transition states. Also, the proposed speech recognition algorithm is designed to detect the inter-phoneme segmentation during the recognition processing.

This study was to investigate the ideal model of community recreation center by using qualitative research, and to interpret the inquiry for recreation center and facility of the specific residents who live in a certain district which is called Gu of Seoul. As qualitative research approach, 6 research participants were recruited by random, cluster arid convenience samplings. The age rages were from 16 to 67, and three men and three women were participated Main data collection method was accomplied by interviews, and sub-methods were used by telephone interviews, reflective journal of researchers. collected newspaper and ethnographic data for the specific district. The research conclusion has suggested two categorizations as following : First, in terms of recreation center environment, facility and recreation program were emerged. Good facility which research participants said about the ideal recreation center is consisted of thee components such as traffic condition, member fee and center space. Program was recognized by selected recreation leader and continuos participation attitude. Second, a degree of service quality is emerged as the significant factor. It depended upon the degree of free using condition and management of time schedule. Ultimately, this study pursued to suggest two considerations First, Korean society now has to think of well-being of district(Gu) residents by improvement of public recreation support. Second, it will be contributed to go up the life quality as many advanced nations do.

The purpose of this study is to analyze the phenomenon of scuba divers who visit a specific diving point as a leisure activity in terms of the concept of place attachment. Study on the place attachment has not been so popular in Korean Leisure studies so that in this study, the method of phenomenological approach had been used due to lack of literature reviews. Total five research informants had been chosen as the participants and we used the method of in-depth interview, participating observation and field note. Collected data was in process of coding, conceptualization and categorization for data analysis. Also to test the validity and credibility, the study had been tested by the method of peer de-briefing and members check. The results are as follows: Firstly, the participants would like to prefer the great atmosphere under the sea. Secondly, massive rock bed made by volcanic action is an attractive factor for research informants. Thirdly, they would enjoy the diving with safety. Lastly, they prefer the legally allowed for catching under water creatures such as shells and sea cucumber.

This study was to explore a theoretical modeling for serious leisure of running mania by using grounded theory. External stimulus as context and entering into running as casual condition made it possible to get flow toward running experience. However, constraints of running as intervening conditions were also interacted and gave bad impacts to runners. Goal and training system, enduring desire for challenge and reconstruction of `running body` as interaction played a great role in reinforcing serious running experience for running mania. This became a consequence. This study was the first trial to suggest a whole process from running motivation to serious running experience in the realm of Leisure Studies.

This study was to explore the leisure participation patterns and leisure problems in the lives of urban workers since a five-day work week has involved. It was explained as follows. Firstly, Several leisure tendancies were manifested in Korean society. Money consumption in the leisure participation became more important in participation after five-day work week. Digital environment effect in the leisure participation is increasing more. Concept of leisure changed more actively, and tendency of leisure is appearing strongly private style called as privatization. Secondly, some problems have been appeared after the five-day work week. The estrangement by economic and age differences has deepened more. Skill absence of leisure participation makes it possible to suffer the syndrome that leisure induces urban workers sickness such as fear and discord in leisure involvement. Finally, public and personal preparations are needed to solve current problems. In this respect, for example, leisure support center as a provisional name should build up, and leisure education program will fulfil extensively. In an addition, the reform of consciousness of urban dweller must be changed.
