The purpose of the present study was to investigate how 4-to 5-year-olds approach a competitive/cooperative task to obtain a resource. Sex and age differences were examined for the behavior and resource utilization of this task. The subjects were 74 same-age, mixed sex groups of 4 children each in three kindergartens in a large city. Each group of 4 children were classmates. The children were videotaped in a play situation where one child could view a cartoon movie (i. e. acquiring a resource) with the assistance of two children (one to turn the film tape and one to push the light-button), and the fourth child was a bystander. Time at each position and physical and verbal behavior constitute the data which were analyzed by ANOVA and ${\chi}^2$. The results of the time analysis showed that children cooperated quickly and were able to view the cartoon(resource utilization) for a large part of the session. High resource utilizers compared with low resource utilizers, exhibited more self-assertive and helping behaviors. Boys achieved more viewing time while girls were bystanders for a greater amount of time. Boys showed more physical and verbal behaviors during the task. Four-year-olds achieved less viewing time than 5-year-olds, indicating 4-year-olds were less effective in eliciting the help of their peers.

We studied the effects of behavior modification and aerobic exercise on body weight, degree of obesity, % body fat, triceps skinfold thickness, blood pressure and eating behavior among overweight middle school girls. 15 girls participated in the behavior modification program by joining 60-90 minute group session weekly. The aerobic exercise program was given to 13 girls 3 times per week with 60 minutes each time. The data were obtained before treatment, after 4 and 8 weeks after treatment. In analyzing the data, repeated measures ANOVA were adopted. The results were as follows ; 1. For the changes of body weight between 2 groups, body weight of behavior modification groups decreased significantly than these of aerobic exercise group at 4 and 8 weeks after treatment, 2. For the changes of degree of obesity between 2 groups, there were no significant differences over time, 3. The analysis of change of % body fat did not reveal significant differences between 2 groups over time, 4. The changes of triceps skinfold thickness were significant differences between 2 groups over time, 5. For the changes of systolic blood pressure between 2 groups, there were significant differences over time. At 4 weeks after treatment, systolic blood pressure of behavior modification group decreased significantly than these of aerobic exercise group. 6. The changes of diastolic blood pressure were significant differences between 2 groups over time.

Purpose: The Purpose of this study was to investigate the effects of the '5&6 smoking cessation program - six classes in five weeks' on the high school students' perception and smoking behavior. Methods: The data collection was done from November to December, 2006. This study was designed using nonequivalent control group pretest - posttest. Experimental group had 24 students, control group had 41 students. The '5&6 smoking cessation program' was applied to the experimental group for two hours per session during five weeks. Data analysis was done using descriptive statistics, X2-test, Fisher's exact test, Independent-samples t-test, Paired t-test, Cronbach's coefficient alpha. Results: The experimental group showed significant increase on smoking self-efficacy, stage of smoking cessation behavior change and significant decrease on daily smoking amount, dependancy of nicotine, urine cotinine level than control group. But the experimental group was not significantly changed at self-awareness, Pros. for smoking and Cons. for smoking. Conclusion: In conclusion, the results of this study showed that the 5&6 smoking cessation program, which focuses on self-awareness, is effective in adolescent's smoking cessation behaviors.

The treatment for patients with mutational dysphonia typically is useful with vegetative phonation, but has not yet been studied. This study attempts to identify the effect of $SKTCLP^{(R)}$ using throat clearing and laughing in patients with mutational dysphonia. The study, which was designed by the author, included 26 patients aged from 14 to 32 years (mean: 18.7 years) who had been diagnosed with mutational dysphonia between January 2007 and June 2010. Voice therapy for these patients included $SKTCLP^{(R)}$, ranging from two to seven sessions (mean: 3.8 sessions). Results were evaluated by videostroboscopy, perceptual evaluation of GRBAS scale, aerodynamic test, and acoustic analysis before and after therapy. Most patients could phonate with low pitch from the beginning and sustain with normal pitch sound in the last session. We had found that glottic gap reduced after therapy and anterior-posterior compression of superior laryngeal part at the first time, and these patients had complete closure of the glottis after treatment. The results of acoustic and aerodynamic measures after treatment indicated significant decreases in Fo, Jitter, Shimmer, SFF, and SPI, and increases in MPT, Psub, and vocal efficiency (p<.05). $SKTCLP^{(R)}$ may be a useful treatment method in managing mutational dysphonia. We can suggest this technique may be useful in improving the voice quality of other functional dysphonia having glottal chink or functional aphonia.

The third generation mobile communication needs to provide multimedia service with increased data rates. Thus an efficient allocation of radio and network resources is very important. This paper models the 'burst switching' as an efficient radio resource allocation scheme and the performance is compared to the circuit and packet switching. In burst switching, radio resource is allocated to a call for the duration of data bursts rather than an entire session or a single packet as in the case of circuit and packet switching. After a stream of data burst, if a packet does not arrive during timer2 value ($\tau_{2}$), the channel of physical layer is released and the call stays in suspended state. Again if a packet does not arrive for timerl value ($\tau_{1}$) in the suspended state, the upper layer is also released. Thus the two timer values to minimize the sum of access delay and queuing delay need to be determined. In this paper, we focus on the decision of $\tau_{2}$ which minimizes the access and queueing delay with the assumption that traffic arrivals follow Poison process. The simulation, however, is performed with Pareto distribution which well describes the bursty traffic. The computational results show that the delay and the packet loss probability by the burst switching is dramatically reduced compared to the packet switching.

The purpose of this study is to suggest an improved model of the library administrative organization, based on analysis and investigation of present situations of libraries in 31 local governments of Gyeonggi province. With the result of this investigation, there are few local governments in Gyeonggi province with library-related organizations. Most of them had more organized position of extraordinary session than of affiliation with each local government. Also, library policy departments were incomplete, and local governments did not configure the library operating System(central library - base library - branch library) efficiently.
