This study was conducted to find out an appropriate means for preventing the juvenile delinquency (JD), which is supposed to be greatly realted to family environment. The data were collected through a questionnaire survey with a means of writing by themself, to 257 middle and high school students and 309 juvenile delinquents who were in confinement. The questionnaire was consisted of 27 items of juvenile delinquencies, 15 questions about personal environment in their period of childhood, 36 questions on their home atmosphere, 25 items with regard to their parental behavior to their children in the rearing of them. The extent of delinquency was calculated by summing the numbers of experienced delinquencies of the listed items. The study subjects were divided into two groups; student group (SG) and juvenile delinquent group (JDG) and the collected data were analyzed with the extent of delinquency in each group by SPSS/PC+statistical package. The extent of JD was increased as the study subjects grew older, defective families were more common, total family income was more poor, parents' educational level was lower, personal expenses were higher and the conflicts between parents were more high in JDG as compared with of SG. The differences were statistically significant. As long as the extent of delinquency is concerned, delimquent points of JDG were significantly higher as compared with that of SG in all items except one item, below the primary school item in fathers' educational level. (In order to prevent JD in our country, it is recommended that educational level and the living standared of the lower class people should be raised, the sound families which do have less conflictsshould be established as much as possible, the present educational system which is making much conflicts between parents and their offsprings should be changed so that their given temperament would be brought up to the highest level, defective families should be reduced as much as possible and adults should not do actions that are considered not to be done by youngsters and must set a good example.)

High output heart failure due to congenital arteriovenous fistula is a rare disease and is difficult to treat. A 27 year old man, suffering from dyspnea, palpitation, lower extremity edema, and abdominal distension admitted May, 1987. At admission there were continuous thrill and bruit at left supraclavicular and infraclavicular area. The heart sound was irregular and rapid, and grade IV/VI pansystolic murmur was audible at the apex. Chest PA showed marked cardiomegaly with pleural effusion and notching at superior aspect of left 2nd rib. Selective left subclavian artery angiogram showed extensive congenital arteriovenous fistula at the area of left subclavian artery and its branches. After setrial feeding artery embolization and palliative operation, the fistula size decreased much with clinical improvement.

9 cases of criss-cross heart anomaly, diagnosed by angiography from April, 1979 to Feb. 1985 at Seoul National University Hospital were reviewed. The results were as follows: 1. Of 9 cases, 6 cases were male and 3 cases werefemale and the age ranged from 2 months to 16 years of age. 2. Of 9 cases, 7 cases were concordant (D-loop) and 2cases were discordant (L-loop). segmental approaches are 2 cases of SDD(TGV) and each one case of SLD(TGV),SDD(DORV), SDL(DORV), SDD(DOLV), SLL(corrected TGV), and normal one. 3. Associated anomalies are small sized rightventricle (7 cases), especially inflow tract and sinus portion, pulmonary outflow tract obstruction(5 cases),VSD(9 cases), ASD( 7 cases), PDA(2 cases) and visceroatrial situs solitus was observed in all 9 cases but 1dextrocardia.

PURPOSE: The purpose of this study was to compare the cleansing performance of a distilled water, a diluted solution of sodium hypochlorite as a household bleaching cleanser and three alkaline peroxide cleansers in vivo plaque deposits by using scanning electron microscope. MATERIALS AND METHODS: Five individuals were selected from department of the prosthodontics in Pusan National University Hospital, and each of them was inserted with specimens for plaque accumulation in their temporary dentures for 48 hours. The specimens were removed and cleaned by each cleansing agents for 8 hours. Scanning electron micrographs were made from the specimens at a magnification of x2,000. A panel of ten persons with a dental or paradental background, but not directly involved in the study, was selected to analyze the photomicrographs to determine which denture cleanser was more effective in removing plaque. RESULTS: Diluted solution of sodium hypochlorite was the most effective at removing plaque following Polident(R), Cleadent(R)e, Bonyplus(R) and distilled water in order. But there was no significant difference of cleansing efficacy between diluted solution of sodium hypochlorite and Polident(R), Polident(R) and Cleadent(R)e, Cleadent(R)e and Bonyplus(R), respectively (P > .05). Alkaline peroxide cleansers by themselves cannot adequately remove accumulated plaque deposits, especially if the deposits are heavy. Corrosion could be seen on the surface of non-precious alloy specimens immersed in diluted solution of sodium hypochlorite. CONCLUSION: It is recommended to use of alkaline peroxide type cleansers with brushing whenever possible, since denture cleanliness is often poor due to the relative inefficiency of these cleansers.

BACKGROUND AND OBJECTIVES: The use of intraoperative facial nerve monitoring (IOFNM) improves facial nerve outcomes in acoustic neuroma surgeries, but the role of IOFNM in middle ear and mastoid surgeries is poorly defined. This study was performed to evaluate the role of IOFNM in middle ear and mastoid surgeries and to systemize IOFNM. SUBJECTS AND METHOD :We carried out a prospective study of 83 patients who undertook middle ear and mastoid surgeries with IOFNM. We checked the facial nerve dehiscence and estimated its location and length using a surgical microscope ('surgical dehiscence'). We stimulated the facial nerve with constant current, unipolar stimulation using Nerve Integrity Monitor (NIM)-2(TM) (Xomed (TM), U.S.A.) and estimated the minimal threshold of electric current making the electromusculography of facial muscle changes. RESULTS: Thirty six (43.4%) of 83 cases showed 'surgical dehiscence' and all responded to 0.7 mA or less of electrical stimulation. The most common site of 'surgical dehiscence' was middle portion of the tympanic segment. We defined the response to electrical stimulation within 0.7 mA as 'electrical dehiscence.' 'Electrical dehiscence' was presented in 63 (75.9%) cases and 82.5% of these cases responded to stimulation of 0.4 mA or less. The mean threshold of minimal electrical stimulation was 0.28 mA for tympanic segment and 0.48 mA for mastoid segment. CONCLUSION: "Electrical dehiscence" based on responses of electrical stimulation is safer than "surgical dehiscence," which is based on microscopic observation in middle ear and mastoid surgery. Based on this study, we recommend the electrical stimulation of 0.7 mA for first screening and 0.4 mA for second exploration in defining facial nerve using intraoperative NIM-2(TM) monitoring in middle ear and mastoid surgeries.

For treatment of partially edentulous patients, a treatment using implant is widely used. Treatment method using implant are implant fixed prostheses and removable partial dentures, and for patients with severe bone resorption, removable implant overdenture with the effects of aesthetic and reducing cost can be used as treatment options. Specially, prosthesis with milled-bar and attachment has the effect of being splinted between implant fixtures, higher retention and stability than conventional removable partial denture. And it has the effect of improvement of aesthetic through lip support by denture base. In this case, the patient with severe alveolar bone resorption and partial edentulous maxilla and mandible was treated by implant-assisted removable partial denture using Milled-bar and ADD-TOC attachment. The esthetic was improved by removing the clasp because of effects of additional retention by using the attachment, and reducing palatal coverage of implant-assisted removable partial denture. The clinical results were satisfactory on the aspect of aesthetic and masticatory function.
