For the purposes of augmentation of the aid for case analysis and diagnosis of malocclusion, a roentgenocephalometric study was made form 84 Korean adolescences. The Subjects consist of 42 males and 42 females aged from 17 to 20 years with normal occlusion and acceptable facial appearance. The author measured 18 angles and 14 linear distances as suggested by Jarabak. The following results were obtained. 1) Each linear measurement of the males' skull was greaten than that of the females. 2) The posterior to anterior facial height was 69.2% in the males and 67.1% in the females. 3) In the relationship of upper lip to esthetic line, the lip of females was more behind than that of males. 4) Saddle angle was 124.7。, articular angle was 148.7。, gonial angle was 119.4。 and upper and lower gonial angles were 45.1。(N-Go-a。) and 74.2。(N-Go-Me。). 5) The ratio of mandibular body to anterior cranial base was about 1:1.1. 6) The angulations of SNA。, SNB。 and SNP。 were as follows; SNA。, 80.3。, SNB。, 79.8。, SNP。, 81.1。. 7) The angle of the sella-nasion plane to the mandibular plane (SNG。Me。) was 32.0。 and that of the occlusal plane to the mandibular plane was 18.2。. 8) The angle of the maxillary central incisor to the sellanasion plane (1-SN。) was 105.6。. That of the mandibular central incisor to the mandibular plane (1-GoMe。) was 94.0。, and the interincisal angle (1 to 1。) was 127.6。. 9) The linear distance from incisal edge of upper central incisor to facial plane was 8.0mm and that of lower central incisor was 4.6mm. 10) In the relationship of the lower lip to the esthetic line, the lower lip was 0.2mm front of the esthetic line.

We tried to evaluate frequencies and severities of malocclusion of various socioeconomic areas according to growth and development. To obtain objective validity, we used Handicapping Labiolingual Deviation(HLD) suggested by Draker, Treatment Priority Index(TPI) by Grainger, Handicapped Malocclusion Assessing Record(HMAR) by American Dental Association and American Association of Orthodontist. Seoul and Kwangju were selected as an urban group, Ahnyang as an middle socioeconomic group and Hwasun near the Kwangju area as an rural group. 140 (male 63, female 73) of 5th grade in 'E' elementary school students in Seoul, 202 (male 101, female 101) of 'S' elementary school students in Kwangju, 207(male 105, female 102) of 'H' elementary school students in Hwasun, and 100(male 49, female 51) of 'M' elementary school students of in Ahnyang of all the same grade were analyzed and we obtained the results as follows ; 1. TPI, HLD, and HMAR showed high coincidence and reproducibility between different observer. (p<0.01) 2. In comparison of TPI, HLD, and HMAR according to clinical decision, there was statistically difference between each other. (p<0.01) 3. As the severity of malocclusion increases there was high correlation between TPI and HLD, and between HLD and HMAR. (p<0.05) 4. With respect to differences between areas in TPI and HLD, there was statistically difference between Ahnyang and other areas. 5. In Seoul as an urban group there was a high incidence of periodic checkup and history of orthodontic treatment than other area. 6. Mode of feeding and posture during sleeping did not affect the severity of malocclusion. As a conclusion, TPI, HLD and HMAR are so reproducible and coincident that they can be used as a guide on evaluating the frequency and severity of malocclusion and determining the priority of orthodontic treatment to determine the need and supply of orthodontic treatment. Furthermore these indices can provide objectively valid data for establishing public health problem solution.

As a part of chemical study on the bioactive metabolites from marine organisms, we have investigated cytotoxicity using brine shrimp bioassay for each solvent fractions of the marine algae(12 species), marine sponges(3 species), coelenterates(2 species), echinoderms(4 species), marine molluscs(17 species), and ascidians(2 species), respectively. As the results, chloroform extract of Stichopus japonicus (LC_50 : 274 ㎍/ml), ethyl acetate extract of Anthocidaris crassispina(LC_50 : 121 ㎍/ml), n-butanol extract of Undaria pinnatifida (LC_50 : 178 ㎍/ml), and water extract of Thais clavigera (LC_50 : 61 ㎍/ml), displayed the most significant cytotoxic activity against brine shrimp. Among the marine organisms tested, echinoderms and marine molluscs were thought to be the most active Phylums on screening of new bioactive compounds.
