The replacement of dental restorations due to secondary caries is a continuing problem in restorative dentistry. The secondary caries can be partly prevented by using fluoride containing dental materials such as glass ionomer cement, which releases and be recharged with fluoride ion acting as a fluoride reservoir. For the purpose of investigating the behaviors of fluoride release and recharge of conventional and high viscosity glass ionomer cements, the experiment was performed on the seven specimens each from 4 kinds of materials ; 1 kind of conventional glass ionomer cement, 2 kinds of high viscosity glass ionomer cements and 1 kind of composite resin. The amount of fluoride release was measured over 7 days with pH/ion meter and fluoride specific electrode. After measuring daily fluoride release, the specimens were recharged with 2% NaF solutions for 4 minutes and measured for 3 days with recharging repeated two consecutive times. The results were as follows : 1. Significantly more fluoride was released at first day after recharge in all materials except Z-100. 2. High viscosity glass ionomer cements released more or nearly equal amount of fluoride after recharge compared with the initial release(P<0.05). 3. The fluoride release after recharge with 2% NaF solution was in order of Fuji IX, Ketac Fil, Ketac Molar, Z-100.

The present study was performed to observe the effect of phytoncide on oral normal microflora and the inhibitory effect of the surviving resident oral bacteria on Pr. intermedia. In this study, saliva from each of 20 healthy subjects was treated with 1% phytoncide from Japanese Hinoki (Chamaecyparis obtusa Sieb. et Zucc.). Surviving salivary bacteria were isolated on blood agar plates and identified by 16S rDNA sequencing. In order to select inhibitory isolates against Pr. intermedia, the isolates from the phytoncide-treated saliva were cultured with Pr. intermedia. The results were as follows: 1. Among the 200 surviving resident oral bacterium, 148(74.0%) bacterium inhibit the growth of Pr. intermedia on blood agar plates. 2. The 200 surviving resident oral bacterium were 109 Streptococcus salivarius(54.5%), 25 Streptococcus sanguinis(12.5%), 15 Streptococcus mitis(7.5%). 3. Among the 148 bacteria which inhibit Pr. intermedia, Streptococcus salivarius was 85.3%(93/109), Streptococcus sanguinis was 64.0%.(16/25), Streptococcus mitis was 54.3%(8/15), Streptococcus parasanguinis was 66.7%(6/9), and Streptococcus Alactolyticus was 100%(8/8). Taken together, among the surviving resident oral bacterium, Streptococcus salivarius, Streptococcus sanguinis, Streptococcus mitis were mainly observed to inhibit Pr. intermedia. and they may exert an additional inhibitory activity against the periodontopathic bacterium. Therefore, phytoncide can be used for preventing and ceasing the progress of periodontal disease and halitosis, and thus is expect to promote oral health.

Ship-floating object accidents can lead not only to a delay in ship's operations, but also to large scale casualties. Hence, preventive measures are required to avoid them. This study analyzed the spatiotemporal aspects of such collisions based on the data on ship-floating object accidents in sea areas in the last five years, including the collisions in South Korea's territorial seas and exclusive economic zones. We also provide basic data for related research fields. To understand the distribution of the relative density of accidents involving floating objects, the sea area under analysis was visualized as a grid and a two-dimensional histogram was generated. A multinomial logistic regression model was used to analyze the effect of variables such as time of day and season on the collisions. The spatial analysis revealed that the collision density was highest for the areas extending from Geoje Island to Tongyeong, including Jinhae Bay, and that it was high near Jeongok Port in the West Sea and the northern part of Jeju Island. The temporal analysis revealed that the collisions occurred most frequently during the day (71.4%) and in autumn. Furthermore, the likelihood of collision with floating objects was much higher for professional fishing vessels, leisure vessels, and recreational fishing vessels than for cargo vessels during the day and in autumn. The results of this analysis can be used as primary data for the arrangement of Coast Guard vessels, rigid enforcement of regulations, removal of floating objects, and preparation of countermeasures involving preliminary removal of floating objects to prevent accidents by time and season.

In this paper, we propose the basic data for cancer patient management by secondary analysis of data from the National Health and Nutrition Survey(KNHANES) to identify factors related to suicidal thinking of cancer patients over 19 years of age in Korean adults lapse of time. The data were analyzed using the IBM SPSS WIN 22.0 program in order to analyze the demographic, health, and mental characteristics of the subjects in 2009 and 2017. It was analyzed using logistic regression analysis. As a result of the study, the factors related to suicidal thinking in cancer patients were activity restriction and experience of depression in 2009(Negelkerke R²=.384), and age, marital status, activity restriction, and experience of depression in 2017(Negelkerke R²=.525). This study is meaningful in that the factors related to suicidal thoughts in cancer patients were identified according to the lapse of time, and the changes in the related factors were confirmed. Development and application of an intervention program to prevent suicide in cancer patients are necessary.

The purpose of this study is to examine the trajectory of early adolescent aggression and to assess the effects of perceived family factors on it. This study investigated the changes in aggression over time and the effects of three family factors, parental attachment, parental monitoring, and family conflict, on the changes using multilevel modeling. The data from Korea Youth Panel Survey(KYPS) of fourth graders who were followed over five years were analyzed. The results indicated that there was a significant average increase followed by a slight decrease in aggression over time; that is, the data followed a quadratic trend. Parental attachment, parental monitoring, and family conflict had significant time-independent effects on aggression, while only family conflict had a significant time-dependent effect on aggression. These results imply that family factors need to be emphasized in planning prevention and intervention programs to reduce aggression during adolescence.

Various muscular flaps are used in oral and maxillofacial reconstructive surgery for the defects caused by tumor resection and trauma or for the correction of head and neck deformities. The sternocleidomastoid(SCM) muscle may be widely used as a muscular or myocutaneous flap in these lesion. The authors used SCM muscular flap for the expected parotid defect following benign tumor related conservative parotidectomy in three cases. We expected that prevention of post-operative facial deformity, reduction of dead-space and protection of denuded facial nerve etc. is lead by SCM muscular flap. But the total SCM flap can lead to some complications such as "flat neck deformity", limitation of neck movement and overcontouring of parotid defect. Therefore, the authors used split pedicled SCM muscular flap and it lead good favorable results of post-operative functional and esthetic problems.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.
