This study was conducted to compare the awareness, satisfaction, and usage patterns of female-consumers for food-nutrition labeling in Busan. The survey was conducted from April 15 to June 10, 2018 by questionnaire. Degree of perception of food-nutrition labeling was higher among individuals in their 30s, 40s and 50s than those in their 20s, 60s and 70s. The score of verification degree was highest among respondents in their 40s and lowest among those in their 20s and 70s. Degree of demand of individuals in their 70s was lower than that of those in their 60s. Degree of reliability of individuals in their 30s, 40s and 50s was higher than that of those in their 20s, 60s, 70s. Satisfaction degree did not differ significantly among groups. Overall the most common reason to review food labeling was 'to confirm expiry date' (30.8%). Among those in their 20s, the main reason for reviewing nutrition labeling was 'weight control', while it was 'nutrients' among those in their 30s, 40s, 50s, and 60s, and 'health improvement' among those in their 70s. Additionally, 51.3% of the subjects reported that the major reason for difficulty understanding the labeling was 'small letter, various form'. The demand for nutrient contents was highest in sodium. Age was negatively correlated with perception of food-nutrition labeling, demand, need for education and publicity, and nutrition knowledge (P<0.01), whereas it was positively correlated with dietary attitude (P<0.01). There was a strong correlation between demand for food-nutrition labeling and the need for education and publicity regarding food-nutrition labeling (r=0.546). Therefore, education materials and improvement plans based on age should be developed and implemented to inspire individuals to choose more nutritious food and develop a healthy dietary life.

The purpose of this study was to examine the correlation of chronic prostatitis with sexual dysfunction and WBC counts on expressed prostatic secretion(EPS) with symptoms of sexual dysfunction. From 2001. 9. 1 to 2002. 3. 31, chronic prostatitis patients(30 examples) treated for more than 4 weeks were compared with normal group(30 examples) about hypoactive sexual desire disorder, erectile dysfunction, orgasmic disorder and hematospermia. We investigated sexual dysfunction according to the degree of prostatitis, improvement rate of prostatitis and sexual dysfunction. Chronic prostatitis patients compared with normal group were increased significantly in decreased libido(73.3%), erectile dysfunction(51.1%), orgasmic disorder(48.7%) and hematospermia(16.7%). In WBC very many/HPF group compared with others. though sexual dysfunction was highly revealed, but there was no statistic significance. In improvement rate of prostatitis, total improvement rate was 76.7%, WBC 10-30/HPF group 77.8%, WBC many/HPF group 72.8% and WBC very many/HPF group 80%. But the medical cure effect was the highest in WBC 10-30/HPF group. In the improvement rate of sexual dysfunction, total improvement rate was 68.5%, hematospermia 100%, decreased libido 90.9%, erectile dysfunction 67.4% and orgasmic disorder 60.3%. As a result of considering the relation with improvement rate of prostatitis and sexual dysfunction, there was a statistical significance at the erectile dysfunction. orgasmic disorder. The results showed the chronic prostatitis had effects on sexual dysfunction but there was no correlation between the degree of chronic prostatitis with sexual dysfunction. It also showed that the treatment of prostatitis had effects on improvements of erectile dysfunction and orgasmic disorder.

This study was to investigate difference of patients' satisfaction degree concerned with installation of dental labs and the reason. The data for this study were collected through Self-Administered Questionnaires from 284 patients who had visited dental clinics more than two times. The results are as follows: Female respondents ratio was as twice much as male ones. And 54.2% of the respondents were found out to have completed university education. Dental clinics with dental labs scored higher than others in patients' satisfaction and recommendation willingness degree. Dental clinics without dental labs scored higher in patients' revisiting willingness degree. With simple Correlation Analyses it was found out that the most influential variable concerned with patients' general satisfaction degree was medical facility in dental clinics with dental labs, dentist ability to cure in dental clinics without dental labs. There were some discrepancies with other subordinate variables. Through Stepwise Multiful Regression Analyses it was found out that the most influential variable with patients' general satisfaction degree was dentist ability to cure in total and dental clinics without dental labs and medical facility in dental clinics with dental labs. There were also some discrepancies with other subordinate variables.

This study was carried out in order to estimate the effect of heat pump performance by use of thermal tank with 3 seperation plates which were able to divide thermal tank into 3 chambers that have different temperatures levels. For testing the effect of developed thermal tank which was installed for supplying the heat to the paprika greenhouse in Jinju city. The volume of thermal storage tank was designed for $110m^3$ which was able to cover 30% of heating capacity. The temperature difference was 3 degree Celcius between high temperature and low temperature when only heating circulation was made from heat pump to thermal tank. but 5.5 degree Celcius difference was made when heating circulation of heat pump to thermal thank and hot water supplying circulation of thermal tank to greenhouse was done simultaneously. As a result of this study showed that COP of heat pump was increased by 15% or more than that of using normal thermal tank because heat pump was able to take 3 ~ 5 degree Celcius lower thermal thank water constantly.

The ice storage system uses water for low temperature latent heat storage. However, a refrigerator capacity is increased and COP is decreased due to supercooling of water in the course of phase change from solid to liquid. This study investigates the cooling characteristics of the TMA-water clathrate compound including TMA (Tri-methyl-amine, $(CH_3)_3N)$ of $20{\sim}25wt%$ as a low temperature latent heat storage material. The results showed that the phase change temperature and the specific heat is increased and the supercooling degree is decreased as the weight concentration of TMA increased. Especially, the clathrate compound containing TMA 25wt% has the average phase change temperature of $5.8^{\circ}C$, the supercooling degree of $8.0^{\circ}C$ and the specific heat of 3.499 kJ/kgK in the cooling process. This can lead to reduction of operation time of refrigerator in low temperature latent heat storage system and efficiency improvement of refrigerator COP and overall system. Therefore, energy saving and improvement of utilization efficiency are expected.
