The system of this paper designs and implements a used trading system that is commonly used on the Internet. In order to pursue local transactions based on location, we designed the system by dividing the region in consideration of the general characteristics of used transactions that are restricted by transactions through distance and location. To do this, I used MySQL as the database engine and I used PHP, an Internet server-based scripting language, for database interworking. Due to the characteristics of secondary transactions, information security and design of each product are considered.

Primary hyperparathyroidism (PHP) is a disease in which excessive amounts of parathyroid hormone (PTH) are secreted and calcium levels in the blood increase. Hypercalcemia caused by PHP has a major influence on the peripheral nervous system and produces symptoms such as muscle cramps, paresthesia, and proximal muscle weakness. Here we report a rare case of sensory-dominant polyneuropathy caused by PHP, which improved after surgery.

Objective : This study aimed qualitative change of traditional korean medical public health programs (TKM-PHP) by the research of present condition, problems and improvement direction about TKM-PHP. Methods : Data were collected from 222 of 996 public health oriental medical doctors(PHOMD) using the structured questionnaire by e-mail. Collected data were analyzed through frequency analysis, T-test, and ANOVA using SPSS 12.0 and significant level was 0.05. Results : 59.5% of the respondents said that the TKM-PHP are not efficiently executed because there are not enough motivations to entice oriental medical doctors in charge of the programs and because PHOMD and the government officials in charge lack in relevant experiences and skills. A majority of the PHOMD recognize a need for activating the TKM-PHP but less actively participate in the programs since there is not a good rewarding system and there are neither standard manuals nor methodological guidelines for the programs. In order to activate the TKM-PHP, it is urgent to employ full-time oriental medical doctors and to continually and systematically appoint the professional manpower in charge. And it is also needed for the state to secure an adequate budget and prepare schemes for persistently train such professionals. Conclusion : Activating the TKM-PHP will lead to the development of TKM, but there are still such problems as lack of the professional manpower in charge, an excessive burden of the duties of PHOMD, lack of program manuals, and a poor system for evaluation. To solve these problems, it is advised to construct foundations for administerial supports, draw up a standard manual, prepare a system for evaluation in consideration of the characteristics of TKM, and hire professionals to ensure sustainable programs.

Purpose: The purpose of this study was to investigate the effect of oral health education on adolescents. Methods: The subjects were middle school students in a health promoting school in Gunpo, Gyeonggi Province. Before giving the students oral health instruction, their modified Patient Hygiene Performance index (PHP index) was measured using disclosing solution. Then, the students were taught the right way to brush teeth (Rolling method) and use oral hygiene devices such as dental floss, tongue cleaner and interdental brush. Their modified PHP index was re-measured three days after and seven days after the education to evaluate the effect and persistency of oral health education. of the total 116 students, 48 students who completely filled out the questionnaire and participated in the whole process, photo shooting and three times of PHP index measurement, were included in the final analysis. Results: The students' modified PHP index significantly decreased three days after the education. However, the index slightly went back up seven days after the oral health education. Conclusion: Oral health education was effective in reducing dental plaque which remained after brushing. Continuous education about and constant motivation for oral hygiene turned out to be critical to maintain the impact of oral health education. Therefore, it is necessary to develop educational contents which can constantly motivate teenagers.

Objectives: Currently, oral health of the disabled is taken care of by the social workers, not by dental hygienists, who are the oral health professional in this area. Therefore, we aim to enhance the equity of oral health for the disabled by providing the correct oral health care method to social workers residing in the welfare facility for the disabled. Methods: Four dental hygienists and four social workers were given the class I intellectual disabilities living in 'o' welfare facilities for disabled people in Songpa-gu, Seoul from April 13, 2019 to April 20, 2019. Patient Hygiene Performance(PHP) Index were measured and compared. In advance, the social workers were taught brushing (Rolling method), and the method of brushing and measuring tools were integrated. Results: Twice a total of dental hygienists and social workers practiced toothbrushing(Rolling method) for the class I intellectual disabilities who is a person to be brushed. When comparing the Patient Hygiene Performance(PHP) Index after the second round, the result shows that both the first and second dental hygienists' Patient Hygiene Performance(PHP) Index is lower. Conclusions: Comparing oral health knowledge level and Patient Hygiene Performance(PHP) index of dental hygienist and social workers, the result shows that dental hygienist has higher oral health care ability. Therefore, the dental hygienist should be placed in welfare facility for the disabled as an expert in oral health management to create an environment in which the disabled and social workers can be trained. In addition, the curriculum of the college that nurtures the dental hygienists should have a course to understand the characteristics of the disabled person in order to enhance the professionalism of dental hygienists.

The purpose of this study was to investigate the antimicrobial effects and characteristics of protamine extracted from spermary of tuna. The result of amino acids analysis showed that the contents of arginine were 46%. It was 10% lower when compared to standard protamine (SP: Asama kasei LTD, Japan). Also, there were significant difference in the contents of proline adn glycine. The average molecular weights of main protein in TP were 13,400 Da, whereas those in SP were 11,300 Da and 2,600 Da. To increase antimicrobial activities of TP, pepsin or trypsin was treated at $37^{\circ}C$. After TP was hydrolyzed with pepsin (pepsin hydrolyzed protamine: PHP) for 4hrs, the average molecular weights of the main protein were 11,300 Da and 3,900 Da, and the antimicrobial activities were significantly increased compared to TP. After TP was hydrolyzed with trypsin (trypsin hydrolyzed protamine: THP) for more than 10 min, the average molecular weights of the main protein were below 2,500 Da. PHP had higher antimicrobial effects on some gram positive bacteria (Staphylococcus aureus, Lactobacillus helveticus, Lactobacillus plantarum) than SP. However, THP had no antimicrobial activities. When TP was hydrolyzed with pepsin (PHP), its antimicrobial activities increased in the same level with those of SP, and this increase might be resulted rather from the changes of molecular weights of the main protein than from the contents of arginine in protamine.

A self-administered survey was conducted on the dental hygiene students at three different colleges located in Gyeonggi Province and South Chungcheong Province respectively from October, 2013, to the same month of 2014 to grasp their oral health management behavior, differences in plaque index according to plaque index systems and the correlation of the two. And their plaque index was measured. The findings of the study were as follows: 62.8% of the respondents replied they got a dental checkup over the past year, and 84.1% answered they received preventive dental treatment once at least or more. 80.5% replied they used a fluorine-containing dentifrice. 90.9% answered they used the rolling method to brush their teeth, and 50.0% replied it took three minutes to brush their teeth. They got a mean of 27.88 when O'leary index was used among plaque index systems. Their PHP index and PHP-M index were respectively a mean of 1.30 and a mean of 12.12. Their plaque index became lower when they spent more time brushing their teeth, and the toothbrushing time made a statistically significant difference to that (p<0.05). The factor that exerted the largest influence on plaque index was whether to brush teeth for the sake of oral health (B=-9.747, t=-3.752, p<0.001) or not. That made a statistically significant difference to it. The above-mentioned findings illustrated that more patients visited dental clinics than before to receive preventive dental treatment or to get dental checkups, and that toothbrushing time and whether to brush teeth for the sake of oral health or not were identified as the oral health management behaviors to affect plaque index.

The aim of this study was to investigate the effects of dental plaque control depending on the detergent foods. Study design was a nonequivalent control group design. Study subjects were 14 males (38.8%) and 22 females (61.1%), the age of 20.6 years old. It was conducted from March 7 to June 13, 2012. The Patient Hygiene Performance index (PHP index) was measured as a dependent variable. Detergent foods were cucumber, pear, carrot, and peach. The PHP index of detergents foods were compared using ANOVA. Paired t-test was performed. SPSS ver. 18.0 was used for the data analysis. All detergent foods which cucumber ($2.85{\pm}1.01$), pear ($2.82{\pm}0.93$), peach ($2.48{\pm}1.12$), and carrot ($2.75{\pm}0.68$) was a significant decrease in plaque index (p<0.05). However, there was no significant difference among detergent foods. Detergent foods are effective in dental plaque control. However, no difference was shown depending on the detergent foods.

The molecular weight of proteins and protein hydrolysis products (PHP) in the fractionated post-production marinating brines left after herring marination process was determined by the HPLC. The proteins and PHP retention was evaluated in the three-stage purification process with the usage of polypropylene bag ($25{\mu}m$) and ceramic membranes with the cut-off of 150 and 1 kDa. It was found that the process of marination contributes to high participation of compounds in the post-production marinating brines. Those are characterised by low molecular weight, formed as a result of protein hydrolysis. Each stage of the scavenging process was reducing the content of proteins and PHP. The lowest retention was observed in the stage at which a PP bag was used, while the highest in the UF process, with the usage of 150 kDa membrane. The total retention of proteins and PHP differed according to the type of post-production marinating brines and reached the level of 16-22%.
