This study examined the effects of response-facilitating factors(Food-related Knowledge, Response-Efficacy, and Self-Efficacy) and response-inhibiting factors(Severity, Vulnerability, and Consumer Stress) on the consumer’ behavior intention based on protection motivation theory, which explains the behavioral change to protect oneself. This study was conducted to reduce the customers’ concerns regarding food safety accidents and introduce ways to make them more interested in food safety. A sample of 225 adults over 19 years of age was collected in February 2018 through a self-administered questionnaire. The results of the cognitive mediation process of protective motivation theory showed that the consumers’ knowledge and self-efficacy which are response-facilitating factors, positively influence the behavioral intention. Severity and consumer stress were response-inhibiting factors. On the other hand, response-efficacy, which is a response-facilitating factor, and vulnerability, which is a response-inhibiting factor, did not influence the behavioral intention. Therefore, severity and consumer stress are response-inhibiting factors. The results were analyzed as a result of a behavioral change to protect oneself from food safety accidents. The applicability of the theory of protection motivation on the topic of food safety was also confirmed.

Peri-implantitis is an inflammatory lesion of the periodontium surrounding an endosseous implant, with progressive loss of the supporting peri-implant bone. The main purposes of treatment for peri-implantitis due to biological factors include addressing the inflammation and restoring a healthy but reduced periodontium around the implant, similar to the treatment of periodontitis in natural teeth. The proposed treatment protocol includes surgical treatment, mainly resective surgery, after non-surgical treatment such as oral hygiene instructions, mechanical cleansing of the fixture, and general or topical antiseptic or antibiotic application according to the extent of inflammation. In this article, we present a 6-year follow-up case showing unusual marginal bone regeneration after resective surgery and decontamination of an implant surface for the treatment of peri-implantitis and discuss the possible reasons.

STUDY DESIGN: Experimental investigation in vitro. OBJECTIVES: To evaluate the relationship between the degeneration of intervertebral disc cells, and low back pain induced by degeneration of intervertebral disc cells and increases in use of proinflammatory mediators via nicotine stimulation. SUMMARY OF LITERATURE REVIEW: Smoking is a leading cause of degeneration of intervertebral disc cells and low back pain. According to the existing literature, nicotine, one of the main ingredients in cigarettes, causes the degeneration of intervertebral disk cells including decrease of glycoprotein through generation of carboxy-hemoglobin, vasoconstriction, and disability of fibrinolysis and changes of metabolism of nucleus pulposus cells. MATERIALS AND METHODS: Annulus fibrosus of intervertebral disc and knee joint cartilage were collected from pigs; these cells were acquired by gradual enzyme decomposition. Using Trypan blue, concentration and survival rate of cells were examined; cells were inserted on alginate beads for tertiary cultivation. Nicotine was then applied at 0, 50, 100, 200 and 300 nM, respectively, and the samples were cultivated for three, six and nine days, respectively. After collecting culture fluid, it was measured for interleukin(IL)-1beta, IL-6 and IL-8 with the ELISA Test. DNA of cells used for cultivation was quantitated and the amount of the resulting proinflammatory mediator was normalized. The results were then compared with the result of same study on cartilage of porcine knee joints. RESULTS: For changes of the inflammatory mediator based on the concentration of nicotine, in nicotine stimulation with low concentration of 50 nM and the control group, there was no significant change, while transient increases of inflammatory mediator showed in nicotine stimulation with concentrations of 100, 200 nM, respectively. There was not a significant increase of IL-1beta observed in all nicotine stimulation groups; these were the same results in porcine cartilage study. The level of IL-6 in 200, 300 nM nicotine concentration showed significant increases, respectively. The level of IL-8 in high dose nicotine stimulation groups also showed significant increases of DNA on the sixth day. And in porcine cartilage study group, significant changes were observed in 200, 300 nM, but the absolute value was lower than that of annulus fibrous cells group. CONCLUSION: Inflammatory mediators such as IL-6 and IL-8 increased as the result of tertiary cultivation of annulus fibrosus cells of porcine intervertebral disk and nicotine stimulation. It is believed that the cells of the disc annulus are more sensitive than articular chondrocytes to nicotine stimulation. This may be the focus of future long-term studies effects of nicotine other inflammatory cytokines.

PURPOSE: The incidence of bronchopulmonary dysplasia(BPD) may further increase in the coming decade as advances in neonatal intensive care enable clinicians to save even smaller, younger and more critically ill infants. The purpose of this study was to evaluate risk factors and prognosis associated with BPD in premature infants. METHODS: The retrospective review on RDS infants admitted to the neonatal intensive care units at the Chonnam University Hospital was done from Jan. 1995 to July. 1997. These infants were divided into two groups, BPD group(n=25) and non-BPD group(n= 112). The incidence, risk factors and therapeutic results of BPD were analyzed. RESULTS: Infants in the BPD group had lower birth weight, gestational age, and lower 1 min Apgar score compared to that of infants in the control group. The incidence of BPD was 18.2Yo and was higher in male infants. Longer duration of oxygen, ventilatory support and higher PIP were noted in the BPD group. There were no significant differences between the two groups concerning duration of postnatal requirement of oxygen supplementation, ventilatory support, and ventilatory parameters such as FiO2 and PEEP. The incidences of PDA and pneumothorax mean fluid volume and weight loss were similar in two groups. Frequent episodes of respiratory infection occurred(31.6%) in BPD group and one patient expired during 6 to 12 month follow up. 22 infants(88%) received dexamethasone in BPD group. Side effects of dexamethasone including hypertension and hyperglycemia occurred in 59.1% and 31.8%, respectively. CONCLUSION: The overall incidence of BPD was 18.2% and the risk factors for BPD included lower birth weight and gestational age, lower Apgar score at 1 minute, longer duration of oxygen and ventilatory support with higher PIP.
