POF(Polymer optical fiber) offers advantages of lighter, inexpensive, and easier to use over GOF(glass optical fiber). Its higher transmission loss and low bandwidth, however, make it suitable only for short distance networking such as LAN. The polymer materials and its synthesis technology of low transmission loss and the broader application for flexible POF are the two of many critical areas to be investigated more. In the current study, low-noise POF modules are developed and optimized with a low noise amplifier and low cost LED of 650 nm. In order to demonstrate the dynamic characteristics of the POF module for optical communication and sensing, we have built an image transfer module, optical transmission speed measurement module, optical transceiver for RS-232, and sound-transfer module, and the signal characteristics of them are evaluated. It is found that the module can be readily used for a quick and simple measurement of optical transfer speed. With help of analog amplifier, LED, and PD, sound and image transfers through a maximum 60 m optical waveguide have been confirmed. Real-time data transfer was also demonstrated in PID control, which is thought to be valuable to industrial plant design and control.

A shooting game is all game genres that hit targets through shooting. It include a lot of genres from a flying shot of game room to a personal shooting action game. In this point, a shooting game was regarded it as the origin of all game and it was developed from the early days of game. At present we can meet it in an electronic game room or personal computer, and mobile phone etc.. The popularity of shooting game caused to take aim by simple system, interface, and speedy play. Also it was enticed everyone to enjoy it easily. A shooting games is worked from old like ways until recently and a process of playing game is intuitive than another game. Therefore it popular with a PC player as well as persons of all levels. Beginners can train this game easily through direction such as control way of object, advent way of enemy aircraft and scroll way of background. But as an usability of working and controlling game, beginners of game development can pass over a shooting sense that shout and hit basically. And after design, they will feel that cannot convey realistic effect and thrill etc.. At a result, hitting sense happens to graphic elements and sound. Therefore a measure of effect on these elements is started from analysis of good shooting game. This study was to focus on the advance effect of hitting sense in shooting game through analysis centered for 'the Beetlewing' and '1945 Plus'.

The present study examined the effects of the complexity of the 3D models on the results of acoustic simulation which is the predominant tool of the acoustical design of buildings. Also, the effects of the 3D model on the auralized sounds were investigated. In order to carry out the study, four 3D models with different levels of complexity were introduced for a real auditorium which have different numbers of surfaces in the persuit of the guidance of odeon room acoustic software. The set-up of models was also based on the level of transition order of the program. And the acoustic experiments were performed measuring room acoustic parameters including SPL, RT, C80, D50. Acoustic computer simulations were performed using four different models. Then, the results of the computer modeling were compared with the measured acoustical parameters. In addition, sound sources were recorded in the field and auralized sounds were made in convolution with the impulse source made from acoustic modeling. Then, subjective tests were undertaken using auralized sounds. As the results, it was found that the result of the acoustic simulation were closer to the real room acoustic properties when 3D model was more particularly made. For the subjective test, the listening materials were acknowledged as similar with the real sound source when more complex 3D model was used. Then, it could be concluded that the complexity of the 3D model affects the results of the acoustic modeling as well as subjective tests.

This study was conducted to identify the effect of meridian acupressure on defecation of patients with post spinal operation. The nonequivalent control group posttest only design was used. The data were obtained from 77 post spinal operative patients, 34 in the experimental 43 in control group in Y Hospital, Seoul, Korea. The neurosurgical unit A and B ward, assigned by matched sample by the name of operation such as laminectomy and posterior lumbar interbody fusion are performed. Meridian acupressure meant the method that an examiner presses response points distributed in the pass of energy vessel. In this study, meridian acupressure program was performed on as points in order of Hegue (LI-4), Zhigou (TE-6), Zusanli (S-36), Shangjuxu (S-37), Xiajuxu (S-39), Tianshu (S-25), Taichong (L-3) which was known to be related to large intestine. Data were collected from 1, July 2003 to 1, September 2003. Meridian acupressure program was carried out for 20 minutes 4 hours after operation twice daily. In order to evaluate the effect of meridian acupressure intervention, they were asked time of bowel recovery, gas passing, and defecation though questionnaire method. Data were analyzed by the SPSS/ WIN 11.0 program. The results of this study were summarized as follows; 1. Homogeneity tests of general characteristics and operation related characteristics of the experimental group and the control group were performed. General characteristics included age, sex, defecation habit, eating pattern, fluid intake, life style, activity, usage of laxative and etc. 2. Hypotheses were verification as follows; 1) Recovery of bowel sound of the experimental group who received meridian acupressure intervention was faster than that of the control group after spinal operation (t=-6.770,P=.000). 2) Time of gas passing of the experimental group who received meridian acupressure program was faster than that of the control group after spinal operation (t=-8.003, P=.000). 3) Time to defecation of the experimental group who received meridian acupressure program was faster than that of the control group after spinal operation (t=-9.026, P=.000). 4) Abdominal discomfort due to defecation of the experimental group who received meridian acupressure program was lesser than that of the control group after spinal operation (t=-3.431, P=.001). From these results, meridian acupressure intervention was effective for recovery of bowel sound, reduce time to gas passing, time to defecation and lessen abdominal discomfort due to defecation on post spinal operative patients. And therefore this intervention can probably considered on clinical practice.

Previous studies of music, user interface, and human-computer interaction have used sounds which include musical structure rather than real music. This study investigated whether real music affects objective and perceived usability. Silence, sound, and music conditions were compared in experiment 1 (kimchi refrigerator) and 2 (remote controller for air conditioner). Participants' performances of reaction time and accuracy, and the degree of subjective satisfaction were analyzed. The results showed that main effects on task performances were not different significantly; however, perceived usability of music condition was better than sound condition, which was better than silence condition. It means that musical user interface improves perceived usability while not interfering task performance. This study provides a basis of emotional and aesthetic effects of music in home appliances design, and can be applied to studies for the blind. More specific guideline for the musical user interface can be drafted if further studies consider more various tasks, context, musical structure and types for the appliances.

Statement of problem. The current trend in prosthodontics is the adoption of a conservative approach to preparing dental prostheses by minimizing the amount of sound tooth structure removal during preparation. Purpose. The major disadvantage of the adhesion bridge is the inherently poor resistance to dislodgement that its use in areas subjected to high occlusal load is limited. The purpose of this study was to compare the dislodgement resistance of $Bio-pin^{(R)}$, conventional 3-unit and adhesion bridges. Material and methods. The experimental groups were classified as follows : Group I : 3-unit bridge cemented using $Super-Bond^{(R)}$ C&B Group II : Adhesion bridge cemented using $Super-Bond^{(R)}$ C&B Group III : $Bio-pin^{(R)}$ design adhesion bridge without incorporation of $Bio-pin^{(R)}$ (cemented using $Super-Bond^{(R)}$ C&B) Group IV-1 : $Bio-pin^{(R)}$ retained adhesion bridge incorporating a single $Bio-pin^{(R)}$ (cemented using $Super-Bond^{(R)}$ C&B) Group IV-2 : $Bio-pin^{(R)}$ retained adhesion bridge incorporating a single $Bio-pin^{(R)}$ (cemented using $Panavia^{(R)}$ F) Group V : $Bio-pin^{(R)}$ retained adhesion bridge incorporating two $Bio-pins^{(R)}$ (cemented using $Super-Bond^{(R)}$ C&B) Results. The results of this study were as follows : 1. Significant differences in dislodgement resistance of the restorations were found between Group I, Group II and Group III (p<0.05). No significant differences in dislodgement resistance of the restorations were observed between Group I Group IV-1 and Group V. However, there were significant differences in dislodgement resistance between Group II and the other groups (p<0.05). 2. No significant differences in dislodgement resistance of the restorations were observed between GroupIV-1 and GroupIV-2, both of which utilized a single $Bio-pin^{(R)}$. However, significant differences were observed when Group III was compared to either GroupIV-1 or Group V (p<0.05). 3. No significant differences in dislodgement resistance relative to the type of dental cements used were found. Conclusion. From the above results, it is concluded that the dislodgement resistance of $Bio-pin^{(R)}$ bridge restorations utilizing a single $Bio-pin^{(R)}$ is similar to that of a conventional 3-unit bridge. The results also suggest that $Bio-pin^{(R)}$ bridge restorations using a single $Bio-pin^{(R)}$ are a viable alternative to the conventional 3-unit bridge when minimal removal of sound tooth structure and fulfillment of both function and esthetic aspects are considered.

1. Objectives The purpose of this study lies on the objectification of the Sasang Constitutional diagnosis. This study was analyzing the constitutional characteristic of adult men voices by PSSC-2004. 2. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 231 adult men voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 231 was composed with 5 Taeyangins, 32 Soyangins, 102 Taeumins and 92 Soeumins. The under 55 years old group was composed with 4 Taeyangins, 23 Soyangins, 83 Taeumins and 77 Soeumins. The over 55 year-old group was composed with 1 Taeyangin, 9 Soyangins, 19 Taeumins and 15 Soeumins. 3. Results 1) In total group, the Soeumin's mean value of center pitch(4)$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.034). 2) In total group, the Soeumin's group 3 APQ was significantly low compared with the others (P=0.042). 3) In under 55 year-old group, the Soeumin's center value of center pitch 4$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.025) 4) In over 55 year-old group, no statistical significance was found between the Taeyangin, Soyangin, Taeumin and Soeumin. 4. Conclusions In under 55 year-old group, Soeumin's voice showed high pitched sound (clearness) at the low frequency (1000-2000Hz). In over 55 year-old group, there is no significant differences. This fits in with that 'Soeumin's voice is 'Yu-tone' born by 'Shang-tone', very short and high.' 'Yu-tone' corresponds to 'Ra' and witch is highest among Gong, Shang, Gao, Chi and Yu. This is related with the appearance that the Soeumin's voice is weak, thin and high tone. Therefore it is supposed that Soeumin adult men's voices are thick, and there are vibrations of the ending. It is accepted one of the Soeumin's characters like as a mild tremor of limbs and deep breath caused by Soeumin's Qi-deficiency. This outcome accords with the theory that Soeumin's Qi is less than the Other constitutions.

This study was conducted to identify the effectiveness of meridian acupressure for enhancement of post operative bowel movement to the patient with absolute bed rest who having surgery under general anesthesia. This study used a qusai experimental, nonequivalent control group post test only design. This subject were 44 patients, 22 for the experimental and 22 for the control group, who were admitted at KyungHee University hospital, neurosurgical unit A and B ward, assigned by matched sample by the name of operation who having microvascular decompression and laminectomy. Date were collected from May 1, 2001 to June 30, 2001 by auscultation, self report and by using 7 point face scale. The recovery of bowel sound were measured every 4 hours until gas out for 1 minute auscultation on lower abdomen after 4 hours having surgery. The time of gas out were measured by self report, the severity of nausea were measured every 4 hours for 7 point face scale and also the degree of satisfaction of nursing care were measured after 2 days having surgery with same scale. Data were analyzed with $X^2$, t-test, repeated measures ANOVA and ANOVA. The result of this study were as follows; 1. The experimental group which were implemented with meridian acupressure showed shorter time the recovery of bowel sound after having surgery than control group(t=-5.112, p=.0001). 2. The experimental group which were implemented with meridian acupressure showed shorter time of gas after having surgery than control group(t=-4.010, p=.0001) 3. The experimental group which were implemented with meridian acupressure showed decreased level of nausea score according to time interval than control group(F=21.995, p=.0001). 4. The experimental group which were implemented with meridian acupressure showed higher the degree of satisfaction of nursing care than control group(t=-4.010, p=.0001). These finding indicate that a meridian acupressure could be a effective nursing intervention for enhancement of post operative bowel movement to the patient with absolute bed rest who having surgery under general anesthesia.
