Purpose: Music intervention has long been used in research of patients undergoing surgical operation in reducing anxiety level and improve surgical outcome. However, there are few studies that have considered a patient's music preference. We investigated the effect of the tailored music intervention which chose music according to the patient's preference on anxiety level and vital signs. Method: The subjects were 50 patients who received regional anesthesia for surgical operation at D hospital in Pohang city from April, 2006 to November, 2006. All of the subjects were randomly assigned either music group (30 subjects) or non-music group (20 subjects). As the patients arrived in the operating room, vital signs were monitored until the subjects were transferred to the recovery room, while Spielberger's STAI-KYZ questionnaires were applied twice to measure preoperative and intra-operative anxiety. The data were analyzed by 2-test, t-test, one-way ANCOVA and repeated measures ANOVA using SPSS 12.0/PC+. Results: There were no significant differences between the two groups on vital signs. All of the vital signs increased when the subjects arrived in the operating room, but decreased quickly once the operation began, regardless of the groups. However, the music group reported significantly less intra-operative anxiety, compared to the non-music group (F=15.208, p<.000), when preoperative anxiety was treated as a covariance. Conclusion: The findings support that the use of music which was chosen by patients during the surgery significantly reduced patient's intra-operative anxiety during regional anesthesia.

The study was intended to investigate the degree of satisfaction and experiences of maternity nursing practice and to examine the relationships between satisfaction and experiences. Data were collected from a college located in Inchon from April 2, 2001 to October 30, 2001. A general characteristics questionnaires, questionnaire for clinical practice satisfaction and maternity nursing clinical checklist were used to measure the satisfaction and experiences of maternity nursing practice. The subject were supposed to record their clinical experience in maternity clinical practice checklist. 153 questionnaires for satisfaction of clinical practice and 178 maternity nursing clinical practice checklists used for analysis. The data were analyzed by SPSS-PC+ program. The results of this study were as follows ; 1) The mean score of satisfaction of clinical practice was 3.34(a perfect score 5) and among the 4 categorial components from the questionnaire of satisfaction the score of 'clinical practice teaching' was high(3.85) and 'clinical practice environment(2.91)' and 'clinical practice contents(2.90)' was relatively low. 2) There was significant value between place of clinical practice and clinical practice satisfaction among 7 clinical practice hospital and the most high score of clinical practice satisfaction is 3.70 and the low score is 2.91(F=7.706, p<.001). The score of delivery room was significantly higher than the OBGY room and there was significant value among the place of clinical practice(DR : F= 6.441, p<.001, OBGY room : F=7.908, p<.001). 3) In delivery room, the frequency of observation are 2.61 day, the frequency of practice are 1.33 day and in OBGY room the frequency of observation are 1.73 day, the frequency of practice are 1.31 day for 2 week of maternity clinical practice and the most frequent practice of maternity nursing care was checking vital sign. 4) There were significant relationships between the ranking score of clinical satisfaction and clinical experiences in maternity nursing practice. Based on the results, it is suggested that the satisfaction of clinical practice was related to environment of clinical practice and it is necessary to improve environment of clinical practice and make a strategies to enhance the quality of maternity clinical experience.

실내 음향특성의 컴퓨터 씨뮬레이션 기법은 모형실험 기법과 더불어 건축물의 음향설계 분야에서 널리 사용되는 도구이다. 본 연구에서는 건축물의 음향특성을 설계단계에 예측하기 위해 영상법에 기초한 실내음향 해석 소프트웨어를 개발하였다. 개발된 소프트웨어는 건축물의 3차원 형상모델, 벽면등 반사체의 흡음특성, 음원과 수음점의 위치 등의 데이터를 입력하면, 음선의 전파경로, 수음위치에서의 반사음 패턴, 실내 음향 특성의 평가척 (음의 명료도, 잔향시간 등)을 산출하여 출력하는 기능을 지니고 있다. 기존의 씨뮬레이션 기법이 소요 장비나 비용, 시간적 제약으로 널리 실용화되기 어려웠던 점을 고려하여 PC급에서 간편하게 활용할 수 있도록 개발하였고 음선 전차경로의 그래픽 표현, 반사음 패턴의 분석등, 건축물의 음향 설계를 위한 기능을 부여하는데 중점을 두었다.

In this paper, we propose a Recently, the use of Smart phones surge in youth the youth are becoming a big addiction social problems Mobile Messenger. The prevalence of Smart phones is Mobile Messenger, access time, spatial constraints for assured. As a result, pc room, with a focus on traditional Internet addiction is to be reduced, whereas with a focus on Mobile Messenger Smartphone addiction level is rapidly on the rise. Korea information agency of Internet addiction and mobile addiction risk appeared to be well over 10 percent of the rate of 35% is gaming and mobile addiction unfolds exemplifies the seriousness of Messenger. Addiction is the individual's psychosocial problems such as negative consequences can result, causing the addiction, because it is necessary for an understanding of the mechanism. In this study, Mobile Messenger, the leading factors affecting the addiction said. Mobile Messenger is a major factor causing the addiction habit and consider the user's satisfaction. And social relations and the formation of plougastel Wu Mobile Messenger and its impact on the cause of addiction.

This paper describes the development of a tool management system of milling operations in CIM environment. The system consists of modules for tool room management, tool purchasing, tool magazine management and tool selection. The tool selection is interactively performed by the aid of the graphic icons of milling cutter. The so-called UNICODE tool coding system is also developed to unify different kinds of codes from different tool manufacturers. The system runs on IBM PC AT.

The purpose of this study supply data that can make a living room a more comfortable space by using a plan of furniture usage, that is to say more affective to human's mental and physical character. For this purpose made experiment with slide film on 39 representative descriptions. The object of this research was female university students and to analyze the data. factor analysis. One-way ANOVA and scheffe-test were used by running SPSS PC+ program. The major results are as follows. In experiment with slide film for grasping spatial effect and evaluation on the 39 representative descriptions, three dimensions(clearness. openness. variety) extracted as the result of factor analysis. Especially the result of this study - sizes of space put independent valuables and each demotion put dependent valuables - shows differences according to space’ size.

In this paper, a PC-based real-time microphone array system with small aperture is presented. The microphone array system is based on the generalized sidelobe canceler (GSC) but it employs a new adaptation mode controller (AMC). The performance of the proposed system was evaluated in the Multimedia Room modeled on an office situation. Evaluation experiments show that the proposed system can perform with stable noise suppression.

Two field test installations are discussed. In the first one a new ammonia sensor and an accurate ventilation rate sensor are combined. They are installed in the exhaust chimney in a ventilated pig house. The relative humidity and the room temperature are measured as well. In the second one, an in situ NH$_3$longrightarrowNO converter with subsequent NOx analyser is also being added for accurate ammonia measurement . In this way , the continuous measurement of the total NH$_3$emission can be obtained , the performance of the NH$_3$ sensor can be evaluated, and the ammonia reduction techniques can be tested. The outputs of measurement are fed into a data acquisition system then to a PC in the laboratory. There has been realised the first test installation with which research on the new ammonia sensor is carried out. The primary research results are presented.
