The purpose of this study was to prepare a student and education guideline by examining the college life satisfaction of students studying dental hygiene. Subjects were students going to dental hygiene-related department of three colleges in the Gwangju and Jeonnam areas. College life and life satisfaction was examined at general characteristics. The following results were obtained. 1. Subjects included 35.7% of 1st grade, 33.4% of 2nd grade, and 30.9% of 3rd grade. In the health state, average accounted for the highest percent(76.9%); in the student's associates, a little for the highest percent(76.8%); and in the participation in clubs, no participation for the highest percent(77.1%). 2. For motives to select the dental hygiene, good employment after graduation accounted for the highest percent(61.0%). The highest desired employer was a dental clinic(33.5%), and the highest desired duration was a whole life(61.0%). 3. According to the grade, satisfaction was significantly different in social recognition, major in education, professor, facilities, professor-student, career, and college development(pE0.05). 4. According to the school record, satisfaction was significantly different in social recognition, major in education, professor, professor-student, career, college development, and general life(pE0.01). 5. According to the student's associates, satisfaction was significantly different in social recognition, major in education, professor-student, and general life(pE0.01). 6. According to the participation in clubs, satisfaction was significantly different in professor, facilities, college development, and religious life(pE0.05). In conclusion, as students were in the lower grade, made good school record, had happier associates, and participated in clubs more actively, their satisfaction at college life became higher. Accordingly, professors and school authorities should strive to examine students' actual problem and discuss and resolve them in order to help their effective school life.

Mucoepidermoid carcinoma is one of the most common malignant salivary gland neoplasm. It occurs over a wide age range, and is most common in the parotid gland and usually appears as an asymptomatic swelling. Pain or facial nerve palsy may develop. Minor salivary gland tumors also typically appear as asymptomatic swellings, which are sometimes fluctuant and have blue or red color that can be mistaken clinically for a mucocele. Histopathologically the mucoepidermoid carcinoma is composed of a mixture of mucous-producing cells and squamous (epidermoid) cells. Low-grade tumors show prominent cyst formation, minimal cellular atypia, and relatively high proportion of mucous cells. Mucoepidermoid carcinoma of the minor salivary glands are treated usually by assured surgical excision. For low-grade neoplasm, only a modest margin of surrounding normal tissue may need to be removed, but high-grade or large tumors warrant wider resection. Postoperative radiation therapy also may be used for more aggressive tumors. Mucoepidermoid carcinoma of the oral minor salivary glands generally have a good prognosis, because they are mostly low-to intermediate grade tumors. We present a case of mucoepidermoid carcinoma managed with surgical enucleation and postoperative irradiation and a good clinical result with review of literatures.

The cytologic detection of endometrial carcinoma in Papanicolaou(Pap) smear according to histologic type, grade and stage was studied in 49 patients. The smears of patients who had histologically confirmed were retrospectively evaluated by the Bethesda System. The cytologic diagnosis of endometrial carcinoma was made in 61% (39/49) of patients, atypical glandular cells of undetermined significance (AGCUS) in 16% (8/49) and within normal limits in 23% (11/49). The positive rate for AGCUS and carcinoma was correlated to the histologic type, grade and stage. The cytologic grade revealed a good correlation with histologic grade, too. In conclusion, the presence of cancer cells in Pap smear suggests the tumor in high grade and high stage. Additionally, cytologic detection of AGCUS or carcinoma needs a further diagnostic evaluation. The Pap smear is a valuable method to screen for endometrial carcinoma.

Objective : To investigate the effectiveness of radiographic parameters on segmental instability in the lumbar spine using Kinetic magnetic resonance imaging (MRI). Methods : Segmental motion, defined as excessive (more than 3 mm) translational motion from flexion to extension, was investigated in 309 subjects (927 segments) using Kinetic MRI. Radiographic parameters which can help indicate segmental instability include disc degeneration (DD), facet joint osteoarthritis (FJO), and ligament flavum hypertrophy (LFH). These three radiographic parameters were simultaneously evaluated, and the combinations corresponding to significant segmental instability at each level were determined. Results : The overall incidence of segmental instability was 10.5% at L3-L4, 16.5% at L4-L5, and 7.3% at L5-S1. DD and LFH at L3-L4 and FJO and LFH at L4-L5 were individually associated with segmental instability (p<0.05). At L4-L5, the following combinations had a higher incidence of segmental instability (p<0.05) when compared to other segments : (1) Grade IV DD with grade 3 FJO, (2) Grade 2 or 3 FJO with the presence of LFH, and (3) Grade IV DD with the presence of LFH. At L5-S1, the group with Grade III disc and Grade 3 FJO had a higher incidence of segmental instability than the group with Grade I or II DD and Grade 1 FJO. Conclusion : This study showed that the presences of either Grade IV DD or grade 3 FJO with LFH at L4-L5 were good indicators for segmental instability. Therefore, using these parameters simultaneously in patients with segmental instability would be useful for determining candidacy for surgical treatment.

The vision disturbances of school-age children has been recognized as and important school health problem. The purpose of this study is to describe the current status of the visual health and to explore the related factors for the decrease in visual acuity in the elementary school age children. The study subjects were 697 children (Boys: 338, Girls: 359) of 4th to 6th grade in two school in urban area. The visual acuity data of the school health examination in 1999 and 2000 were utilized for analysis. The questionnaire for children and parents was used for survey. The findings were as follows. 1. The prevalance rate of the children with the visual acuity less than 0.7 on the left eye were 26.84％ ( Grade 4), 31.30％ (Grade 5), and 38.39％ (Grade 6). The rate on the right eye were 28.31％ (Grade4), 30.37％ (Grade 5), and 37.92％ (Grade 6). There was a significant difference in the rate of the visual acuity less than 0.7 according to grade (p<.01). 2.The rate of visual acuity decrease was 40.12％. 3. The factors related to the decrease in the visual acuity were grade, sex, genetic factor, posture, and the awareness of the visual acuity. There was more decrease in the visual acuity when the children were in higher grade (O.R= 1.06), girls (O.R=2.29). Children having parents with better vision (Father: O.R=1.26; Mother O.R= 1.25) showed better vision. On the other hand, when the children have siblings with glasses, there was more decrease in the visual acuity (O.R=2.31). Students with good posture during study (sitting on the chair) and watching TV to the lower direction showed less decrease in the visual acuity. Also, when the students know their visual acuity, the rate of decrease were lower. The variables which odds ratio were statistically significant were sex (p<.01), siblings with glasses (p <.01), and awareness of visual acuity (p<.01).
