To find out the antero-posterior morphology of the upper face in Angle's class III malocclusion patients, 90 patients, adults in Heilman's Dental age, were used as samples and following results were obtained after the relative comparision of antero-posterior relationship of upper facial structures between Angle's class I malocclusion patients and Angle's class III malocclusion patients and of antero-posterior size of upper facial structures to horizontal and vertical structures in each patients. 1. After comparison of the distance from PMV line to anterior margin of maxillary sinus and cheek, which determines the antero-posterior position of the upper face, upper face in Angle's class III patients are underdeveloped relative to Angle's class I patients. The distance between orbitale and anterior margin of maxillary sinus were greater in Angle's class I patients, whic implies thart the upper face in Angle's class III are depressed. 2. Antero-posterior dimension of anterior cranial base from PMV line and vertical dimension of upper face are statistically insignificant between two groups. After comparing antero-posterior position of upper face to anterior cranial base, the upper face in Angle's class Et patients are depressed antero-posteriorly in relation to anterior cranial base. Following the comparision of antero-posterior position of upper face in relation to vertical dimension of upper face, the upper face in Angle's class III patients seem to be narrow antero-posteriorly

The purpose of this study is to determine values and value changes of the four year course nursing college students. The survey was conducted against 262 students of the nursing college, from all classes (freshman, sophomre, junior and senior). This study was conducted during the period of first through 15th of December 1984 in accordance with the L.V. Gordon's“Survey of Interpersonal Values (SIV)”. The results of the study were as follows: 1. Those nursing students surveyed show that conformity (16.32) took the highest place and reconition (10.21) lowest in the general value orientation. In accordance with the Cordon's SIV, those of other woman college students indicate 14%ile-65%ile, respectively. 2. Changes in values by class indicate that freshman, sohpomore and senior students showed similar Pattern but junior students showed significantly lower than other classes. The difference should be considered on the basis of statistics (p <.05). Accordingly, the hypho-thesis 1 of this study has been supported. 3. Significant variation has been shown by each class in each factor such as support, conformity, independence and benevolence but no variation has been indicated in leadership and recognition. 4. There was difference in values between higher class (jounior and senior) students with clinical experience and starting class (freshman and sophomore) students without clinical experience. The study indicates the values of higher class. students is lower than that of starting class. students (P <.05). Therefor, the hyphothesis 2 of this study has been supported. 5. There was no significant difference in values between entering students and graduating students (p<.05), Thus, the hyphothesis 3 of this study has been rejected. The results of the finding of the study show that there is no positive influence in forming the values. for the students. Therefore, it is concluded that new strategy and special educational program should be established for formulation of the right values for the nursing college students.

The purpose of this study was three-fold: i) to investigate the degree of asymmetry in Angle's Class III malocclusion patients and normal adults; ii) to determine the nature of difference existed between two groups; and iii) to investigate the correlationship between the degree of asymmetry and ANB and overbite in Angle's Class III malocclusion patients. The subjects consisted of 25 Angle's Class III malocclusion patients and 25 normal adults and the mean ages were 22.0 and 24.5 years, respectively. Their posteroanterior and lateral cephalograms were traced and analysed with three-dimensional approach. The results were as follows: 1. Asymmetry of Angle's Class III malocclusion group was significant in all regions except cranial base. Their horizontal asymmetry was seen in mandibular angle, maxillary and mandibular 1st molar, mandibular midline and menton. Vertical asymmetry was observed in maxillary 1st molar and mandibular shape and anteroposterior asymmetry in mandibular angle. 2. Nine variables indicating asymmetry were selected and each variable had similar discriminant score. 3. There was a little correlationship between An and asymmetric variable(MSR-B6) and its correlation coefficients was 0.3564. 4. There was no significant correlationship between overbite and asymmetric variables.

In this study, we isolated 12 of Brucella (B.) spp. from cattle, which have been positive in Rose Bangal test and tube agglutination test in Gyeongbuk province in 2009. According to AMOS PCR analysis, isolated 12 strains were identified as B. abortus. Murine derived macrophage, RAW 264.7 cells, were infected with isolated 12 strains or reference strain (B. abortus 544), and bacterial internalization were characterized. According to these results, we divided the isolated strains into the following three groups: class I, lower internalization than that of B. abortus 544; class II, similar internalization to that of that of B. abortus 544; class III, higher internalization than that of B. abortus 544 within RAW 264.7 cells. Furthermore, intracellular growth, bacterial adherent assay, LAMP-1 colocalization, virulence in mice and surface protein pattern were characterized. From these results, representative strains of class III showed lower LAMP-1 colocalization, higher adherent efficiency, higher virulence in mice than those of B. abortus 544, and showed different pattern of surface proteins. These results suggest that B. abortus field strains, isolated from cattle in Korea, possess various virulence properties and higher internalization ability of field strain may have an important role for its virulence expression.

The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.

Objectives : This study aimed to examine to relevance of socioeconomic class recognition and subjective health status of injured workers. Methods : We used data collected over 3years by the Panel Study of Worker's Compensation Insurance(PSWCI; 2015). Data was analyzed using the chi-square test and logistic regression using SPSS ver. 22.0 to verify the relevance between the socioeconomic class recognition and general characteristics of injured workers. Results : First, the income groups of first class, second class and third class were analyzed as being of lower socioeconomic class status, and the income group four class and five class was analyzed as being the middle-ower the socioeconomic class status. Second, the better the subjective health status, higher the perception of socioeconomic class status, as analyzed by Model 1 using only the parameters of socioeconomic status recognition and Model 2 and Model 3 using income class and general characteristics. Conclusions : Health and industrial accident policies are needed to improve awareness of socioeconomic class status of injured workers.

Face mask is an extraoral appliance which used to protract maxilla, and can help in the correction of moderately severe class IlI malocclusions by the anterior displacement of the maxilla and maxillary dentition, and possibly restricting or changing the direction of the growth of the mandible. In three cases the results were followed. 1. Anterior crossbite was corrected 2. Maxilla & maxillary dentition were displaced forwardly. 3. Lingual tipping of the mandibular incisors, and backward & downward rotation of mandible were performed. 4. Acceptable improvement in the class III profile was performed.
