Background: The present study was conducted to determine knowledge level of technicians working in hospitals about testicular cancer (TC) and self-examination of testicles (TSE) and to determine levels of consciousness and implementation status about TSE. Materials and Methods: This cross-sectional study was conducted with technicians working in hospitals (n=243) between $2^{nd}$ January-$31^{st}$ May 2012 at private and governmental hospitals in urban Kayseri. Healthy control subjects (n=235) who were similar to technicians in terms of age, education level and income status were also included to the study. Chi-square test was used in comparison of categorical variables. Results: Technicians were significantly more aware of TC than controls, but the latter were found to have significantly more information about TSE. There was no significant difference between the two groups in terms of knowing how to do TSE and 80% of both groups were unaware this exam. Of technicians, 19.8% and of controls, 25.5% did TSE, the difference being statistically insignificant. First reason for not doing TSE was "not-knowing" among technicians (48.1%) while it was "ignorance" among controls (66.8%). Of technicians doing TSE, 37.5% did as it came to their mind while 51.7% of controls performed TSE several times in the previous year. Technicians were significantly more afraid of getting TC than controls (p=0.037). Conclusions: It was determined in the present study that rates of TSE were similar between technicians and controls. However compliance with the recommended frequency and right method was low. Consequently, public health education should be planned and applied in order to increase the knowledge of TC and TSE.

The objective of our study was to evaluate the dietary intakes and eating habit for seniors utilizing ten different social welfare centers in Seoul, Korea. The total number of subjects of this study was 543(male: 199, female: 344) of 60 years of age or older. The survey was performed through personal interview questionnaires from May 3rd to June 1st 2006. After assigning subjects to four categories based on family type, single, couple, joint family, and other, these categories were compared with the estimated total nutrient intakes and eating habit. Validity was assessed by comparison with 24-hour dietary recalls and dietary variety score(DVS). The results showed that senior in single family type was far lower than that of couple family type in terms of frequency of meal per day and intake of snacks. Dietary variety score represented that a single female with social security beneficiary showed the lowest variety score compared with other family type. The lunch meal provided by social welfare center turned out to be the most nutritious diet and had significant proportion of daily intakes in essential nutrients such as protein, iron, vitamin A, and vitamin C. Taken together, the family type was a significant factor and the accompaniment is another effector on dietary pattern in the elderly. We strongly suggest that the current lunch program in welfare center should be expanded to breakfast meal, and furthermore the small commodity program is also needed to provide the elderly with meal for social communication.

The broth solution was prepared by the mixing of an uranyl nitrate, THFA, PVA, and water. The uranium concentration of the broth solution was $0.5{\sim}0.8$ mole-U/L and the viscosity of it was $30{\sim}80cSt$. The droplets of this broth solution were farmed in air and ammonia by the vibrating nozzle with the frequency of 100 Hz at the amplitude of $100{\sim}130V$. The diameter of the droplet was about $1900{\mu}m$ from using the nozzle diameter of 1 mm. The diameter of the aged gel was about $1400{\mu}m$ after aging in ammonia solution at $60{\sim}80^{\circ}C$, and the dried gel with the diameter of about $900{\mu}m$ was obtained after drying at room temperature or partially vacuum condition. The diameter of the calcined $UO_3$ microsphere after calcination at $600^{\circ}C$ appeared about $800{\mu}m$ in air atmosphere. Although the droplets of the same sizes were formed, the calcined microspheres of different sizes were manufactured in the case of the broth solutions of the different uranium concentration. The droplets of the desired diameters were obtained by the change of the nozzle diameters and the broth flow rates.

In this paper, A duplexer module with temperature-insensitive electrical characteristics was proposed for remote wireless communication system. Duplexer modules are required to have performances of low insertion loss, high isolation between transmitted band and received band, harmonic suppression as well as high power durability in the system for transmitting guided information to missile flying a free space on the ground. The proposed duplexer module are consist of transmission bandpass filter and receiving bandpass filter which are connected to common antenna port, planar coupler for output power monitoring and low pass filter for harmonic attenuation of power amplifier and coaxial cavity resonator. The material and dimensions of the resonator are determined for minimum frequency shift by temperature variation using 3D EM simulation. The measured results of the prototype showed a good agreement with the simulation results, and it should be well applied not only for guided weapon systems but also for any other communication systems such as remote radio head.
