Purpose:This phenomenological study was to describe and to understand nurses' experiences of caring for woman with disability during pregnancy and childbirth. Methods: Participants were 13 nurses from 3 hospitals and 2 local clinics in J city, and were selected through snow-balling method. Data were collected two face to face, semi-structured interviews. The researcher used MP3 player and smart phone for recording as well as transcription process. As for the data analysis, Colaizzi's method was applied. Results: Nurses' experiences were structured as four theme clusters: 'Communicating between/among nurses', 'Recognizing pregnancy and childbirth of woman with disability', 'Taking care of woman with disability based on their differences' and 'Reflecting on nursing care for woman with disability'. Conclusion: It seemed that nurses' recognition to woman with disability and her pregnancy and childbirth was related their nursing care for woman with disability.

무선인터넷 도입 2년을 맞고 있는 국내 이동통신업계 가입자 수의 폭발적인 증가, 다양한 서비스의 제공, 벤쳐들의 모바일 분야 진출러쉬, 해외진출 등 외형적으로 괄목할 만한 성장을 보이고 있다. 하지만 시장참여자들은 하나같이 소문난 잔치에 먹을 것이 없다는 입장이다. 무엇이 문제인가\ulcorner 가장 큰 이유는 무선인터넷의 외적인 성장에 비해 각 player들이 만족할 만한 수익을 거두지 못한 데서 기인한 것이다. 인기에 영합해 모방지형의 단면적인 현행의 비즈니스 모델로는 지속적인 수익창출에 한계가 있기 때문이다. 일찍이 이러한 상황을 맞이한 일본의 경우, 비즈니스모델의 복합화를 통해 수익기반을 확대하거나 아예 바꾸는 등의 노력으로 이러한 상황을 타개해 나가고 있다. 현행 국내 무선인터넷 업계의 문제점 진단과 수익구조 확대를 위한 방안을 제시하고자 한다.

컴퓨터 게임 산업이 발전함에 따라 사용자의 흥미를 측정하거나 불법 소프트웨어 구별을 위해 사용자 분석에 관한 연구가 진행 중이다. 그 예로 최근에 사용자 분석을 통하여 게임 레벨 디자인을 하거나 이를 게임 균형에 이용하는 연구들이 있다. 본 논문은 개인적인 게임 환경에서 사용자의 적절한 게임 경험을 위해 시간열 데이터 마이닝 개념을 이용하여 게임 사용자 모델 분석을 제안한다. 본 논문은 사용자가 게임을 하고 있는 동안 의미 있는 사용자 행동을 저장하고 차원감소와 SOM을 이용하여 4가지 행동 유형으로 클러스터링하고 행동 유형에 따른 사용자를 분석한다.

The purpose of this study was to analyze a change of maximal grip forces and EMG of agonists in upper extremity of 8 professional Ssirum players according to Satbar-grip patterns, to elucidate prime agonist muscles, contribution rate of each muscle, and a difference on EMG in upper extremity. one-way ANOVA(RM) performed for average and maximal values of each player after standardization and statistical significance was set as p<.05. The result includes the following: the highest grip force was A type with a statistic significance using one-way ANOVA and Duncan's comparison between A and C type. In summary the highest grip force was exerted on extension in the wrist than flexion in all grip types. Average and maximal values of biceps brachii and brachioradialis muscles were statistically significant and ones of flexor carpi ulnaris and extensor capi ulnaris were not.

This paper presents an optimized adoption of NVM for the storage system of heterogeneous applications. Our analysis shows that a bulk of I/O does not happen on a single storage partition, but it is varied significantly for different application categories. In particular, journaling I/O accounts for a dominant portion of total I/O in DB applications like OLTP, whereas swap I/O accounts for a large portion of I/O in graph visualization applications, and file I/O accounts for a large portion in web browsers and multimedia players. Based on these observations, we argue that maximizing the performance gain with NVM is not obtained by fixing it as a specific storage partition but varied widely for different applications. Specifically, for graph visualization, DB, and multimedia player applications, using NVM as a swap, a journal, and a file system partitions, respectively, performs well. Our optimized adoption of NVM improves the storage performance by 10-61%.

With the advent of mobile phone, Digital multimedia broadcasting (DMB) service is to be realized for multimedia data communication. For an acoustic part, a smaller and lighter microspeaker is also soon to be realized as an MP3 song player and a speakerphone. Sound quality in the microspeaker is becoming more important in mobile phones. It is evaluated by total harmonic distortion (THD). THD is the proportion of higher order frequencies output response to sinusoidal input signal. It is affected by uneven magnetic distribution and nonlinear response of diaphragm. In this paper, harmonic distortion is analyzed by considering magnetic and mechanical coupling effects. Simulated results of THD are compared with experimental data. Results show that THD in lower frequency range is higher due to high displace on voice coil and high mechanical response of high order frequency.

This thesis describes the development of a service system for small-sized shops which support not only music broadcasting, but editing and generating voice announcement using the TTS(Text-To-Speech) technology. The system has been developed based on web environments with an easy access whenever and wherever it is needed. The system is able to control the sound using silverlight media player based on the ASP .NET 2.0 technology without any additional application software. Use of the Ajax control allows for multiple users to get the maximum load when needed. TTS is built in the server side so that the service can be provided without user's computer. Due to convenience and usefulness of the system, the business sector can provide better service to many shops. Further additional functions such as statistical analysis will undoubtedly help shop management provide desirable services.

The purpose of this article is analyzing the ironic characteristics of MMORPG character. The MMORPG character's ironic characteristics are: inner irony which is caused by relationship between each character, outer irony which is formed by relationship between character and player. The inner irony is based on the heroic role of character and its context. The death and rebirth system of game make the outer irony. The result of analysis shows us that MMORPG is a presentational art and it can give us a profound meaning of life.

A newly developed heuristic algorithm, Harmony Search, is applied to the parameter calibration problem of the nonlinear Muskingum model. The Harmony Search could, mimicking the improvisation of music player, find better parameter values for in the nonlinear Muskingum model than five other methods including another heuristic method, genetic algorithm, in the aspect of SSQ(the sum of the square of the deviations between the observed and routed outflows) as well as in the aspects of SAD(the sum of the absolute value of the deviations), DPO(deviations of peak of routed and actual flows) and DPOT(deviatios of peak time of routed and actual outflow). Harmony Search also has the advantage that it does not require the process of asuming the initial values of desing parameters. The sensitivity analysis of Harmony Memory Considering Rate showed that relatively large values of Harmony Memory Considering Rate makes the Harmony Search converge to a better solution.

In this paper, we present a case study of a new emerging business startup involved in smart house appliances. The irreversible investment concept and real-option theory are introduced as the fundamentals of the model. By using games theory we show that the startup's actions can trigger reactions from other firms. The first part covers initial the research and development stage, while the second part covers production and commercialization. The findings of this study suggest that, given a certain amount of initial investment, an open and shared innovation may lead to hurting a firm's investment while strengthening the competitors' position in the market. However, given the sensitivity analysis, when volatility and demand grow favorably, sharing R&D investment is not a bad option for a new player to adjust its position in the market while still maintaining positive returns.
