The main purpose of this study is to present practical data for the development of the health enhancing programs for the dental hygiene students. This data is based on the investigation of the psychosomatic self-reported symptoms of the dental hygiene students. Out of the random selection of the current dental hygiene students in Gyeonggi-do and Gangwon-do districts. We conducted a survey and analyzed the collected data from 432 respondents. The results are as follows: 1. The mental appeals (19.37) were higher then the physical appeals (17.53) and of the items in psychosomatic symptoms, the point of mental instability the highest (21.85); whereas, that of mouth and anal scored the lowest (14.59). 2. In terms of the religion, statistical significance was shown among physical appeals (p<.01), mental appeals (p<.05), multiple subjective symptom (p<.01), digestive organs (p<.01), aggressiveness (p<.01), nervousness (p<.01), and eye and skin (p<.05), mental instability (p<.05). 3. Concerning the living conditions, Statistical significance was found on the items such as physical appeals (p<.05), mental appeals (p<.01), depression (p<.001), irregular and life (p<.001), multiple subjective symptom (p<.01), lie scale (p<.01) and mouth and anal (p<.05), digestive organs (p<.05). 4. As for regular health check-ups, statistical significance was shown in the following items such as mental appeals (p<.05), depression (p<.01), multiple subjective symptom (p<.05), mental instability (p<.05).

Purpose: The purpose of this study is to evaluate correlation between convergence insufficiency and concentration by evaluating attentiveness in children who have convergence insufficiency symptoms. Methods: The CISS survey and examination for the near point of convergence were conducted to 74 in children aged 12 to 13 years in order to divide them into a normal binocular vision (NBV) and a convergence insufficiency (CI) group. The attentiveness examination was used to all subjects to figure out their emotional problems, hyperactivity and impulsiveness problems, and managerial or functional problems with a 5-point scale. Correlation between convergence insufficiency-related symptoms included in CISS and attentiveness problems was analyzed. Results: there were 29 children (39.2%) in the CI group, the mean scores of CISS of the NBV and CI group were $5.91{\pm}3.69$ and $18.31{\pm}7.00$ each (p<0.001). On the survey of CISS symptoms, children in the CI group frequently expressed such symptoms as eye fatigue, loss of attentiveness, blurry vision, and forgetting the line they have been reading. In the attentiveness examination, the CI group ($74.83{\pm}9.83$) gained higher scores in problematic concentration than the NBV group ($46.80{\pm}11.30$). Convergence insufficiency had significantly positive correlation with total attentiveness (r=0.798). Conclusions: In elementary school students, it has been found that when perceived symptoms related with convergence insufficiency are more serious, problematic attentiveness gets serious, too.

The purpose of this study is to evaluate the effects of continuing work on VDT(video display terminal), therefore this study examined visual fatigue, unaided visual acuity, refractive error, accommodation and horizontal phoria of 152 subjects who did two hour long VDT work. For the ocular symptoms, the greatest number was tired eyes accounting for 45.71%. In the visual symptoms, blurred vision was the hightest rate of 80.39% and in case of systemic symptoms shoulder pain was 33.33% marked top ranking. The average of near visual acuity decresed almost 10% from 0.47 to 0.42, but refractive error increased about 0.10D to the direction of myopic shift. The amplitude of accommodation decreased approximately 0.72D from 7.46D to 6.74D. Accommodation facility was delayed from 2.27 second to 2.50 second, the amplitude of positive relative accommodation was decreased from 4.76D to 4.16D and the amplitude of negative relative accommodation was decreased from 2.46D to 2.33D. The horizontal phoria shifted to the direction of esophoria from $1.82{\Delta}$ to $3.24{\Delta}$.

A 4-year-old neutered female Pekingese dog (weighing 3.6 kg) was referred with the primary complaint of exercise intolerance with occasional syncope. Physical examination revealed irregularly irregular heart rhythm with persistent pulse deficits. The 12-lead surface ECG showed a marked sinus arrest with occasional junctional escape beats, indicating a sick sinus syndrome. Permanent transvenous cardiac pacing with a rate-responsive bipolar implantable pacemaker (VVIR type) was performed in the right ventricle. After pacemaker implantation, the clinical signs were remarkably improved. No further syncopal episodes have yet been occurred after implantation.

Lyme 질환은 미국 코넷티컷주의 라임지방에서 관절염증상을 보이는 소아과환자에게서 1975년 처음 발견되었다, 사슴, 누루, 개 등에 기생하는 진드기에 의해 전염되며, 발병초기에는 감기증상을 수반한 황소의 눈과 비슷한 붉은 반점이 생긴다. 적기에 치료하지 않으면, 관절염, 심장질환, 안면신경마비 등으로 악화될 수 있다. 본 논문의 목적은 두가지로 나누어 볼 수 있다. 먼저, 진단초기의 Lyme질환과 관련된 의료 및 기타 경제적 비용을 저렴하게 계측할 수 있는 방법론을 개발하고 그 유효성을 검증하는 것이다. 둘째로 lyme질환의 비용에 대한 여러종류의 총괄적 계측치를 제공하고 발병의 위험요인을 색출하는 것이다. 본 논문에서는 차트분석이나 임상연구 등 고가의 비용이 수반되는 분석기법 대신에 Lyme질환 다발지역에 대한 설문조사를 실시하고 그 유효성을 재설문조사를 통해서 검증하는 방법을 사용하였다. 자료분석상의 난점은 조사대상자마다 응답하지 않은 항목(Missing Value)이 다르기 때문에, 총 비용을 계산할 때 모든 항목에 응답한 조사대상자만을 사용한다면 표본의 크기가 너무 작아지는 것이었다. 이에 대한 대안으로 총비용 및 부분별 비용의 합을 계산할 때 표본의 일부가 응답하지 않은 항목에 대해서는 그 항목에 응답한 나머지 조사대상자의 응답치 평균을 대체하는 방법을 사용하였다. 통계적 분석결과, 질환의 증상시작부터 설문조사시기까지 Lyme질환과 관련된 사회적 총비용은 US$ 6400으로 추정되었다. 이중에 200가량은 환자의 보호자와 관련된 비용이고 나머지는 환자와 관련되 것이다. 총의료비용의 평균은 계산방법에 따라서 US$ 3000-4200의 범위를 보였다. 응답되지 않은 항목을 해당항목에 대한 응답치평균으로 대체하였을 때 총의료비평균은 US$ 4108이었다. 시간비용을 생산성손실에 대한 사회적 가치와 실제임금 손실의 두가지 방법에 의해 계산되었다. 실제임금손실은 생산손실의 사회적 가치의 약 30%에 불과하였다. 본 논문의 결과는 의료비용 및 비용과 생산성손실에 대한 정보가 지역보건담당자에 의한 전화설문조사에 의해 경제적이고도 일관성 있게 수집될 수 있다는 근거로 해석될 수 있다.

Purpose: This study was to find out the influence on eyes of indoor air quality in college students taking course, such as Sick-building syndrome symptoms and effects on the eye in new-built university buildings. Methods: We selected a new building in a university located in Metro Seoul and college students in a department for the study. The number of total participants was 33, to whom questionnaire surveys were conducted in advance to check individual traits (gender, age, whether to smoke, whether to wear contact lenses, or whether to drink). The first questionnaire surveys and checking of ocular symptoms to first indoor hazardous materials were conducted in October and two months later the second surveys and checking were carried out in December. The indoor air quality was measured when conducting the first questionnaire surveys and the second questionnaire surveys; especially measurements of gaseous materials such as aldehydes and VOCs in the indoor air were conducted. Results: Indoor air quality of the new building was as follows: formaldehyde level was 22.90 ${\mu}g/m^3$ in the first measurement and 16.79 ${\mu}g/m^3$ in the second measurement. In addition, most materials showed higher value in the first measurement. The level of TVOC was statistically significant (p<0.05) decreased on 448.54 ${\mu}g/m^3$ in the first and 62.55 ${\mu}g/m^3$ in the second. In clinical assessments to check ocular symptoms caused by eye irritations, dry eye syndrome was found in the first and second exposures. When comparing the first and second assessments, dry eyes deteriorated in the morning of the second attempt compared to the first one. Conclusions: In the survey of ocular symptoms and the measurement of indoor air quality, the level of formaldehyde was measured higher in the second attempt than the first; thus, it was confirmed the influence of indoor air quality in a new building upon ocular symptoms of occupants.

Purpose: Alport SD., the most common herectitary rephriris, is a renal disease with rapid progression. Deafness, ocular abnormalities and a specific EM finding may be associated in addition to a family history. We have aralyged retrospectively. Methods: We observed 12 children with Alport syndrome who were diagnosed at Dept. of pediatrics in Kyunghee Univ., College of Medicine, from Apr. 1991 until Jun. 1999. We used four criteria for diagnosis: renal disease, family history, deafness or eye abnormalities, and a specific finding in electron microscopy Results: 2 of 12 patients had all features of the four diagnostic criteria. We could not trace an exact family history in 3 patients, and 6 patients did not exhibit deafness or eye abnormality. One could not have renal biopsy because offer chronic renal failure. Other three criteria were observed in her. The ratio of male to female observed was 1:2 respectively and the mean age of initial renal symptom was 5.6 years. 9 of 12 patients had a family history of renal disease. In the audiogram and ocular examination for 11 of 12 cases, sensorineural hearing loss was observed in 6 and ocular abnormality in 2 cases. In electron microscopic finding, irregular thickness of the capillary basement membranes with lamination of lamina densa and foot process obliteration was noted in 9 of 11 and thin basement membrane with splitting and foot process obliteration was noted in the other 2. The mean period of follow-up was 3 6/12 years. And one patient developed the chronic renal failure until now and had kidney transplantation. Conclusion: For the diagnosis of Alport syndrome, the following four diagnostic criteria are very important : renal disease, family history, deafness or eye abnormalities, and a specific finding on electron microscopy. We expect that more patients can be detected through the analysis of these characteristics.

The purpose of this study was to perform a clinical test using ez NANOsence II RGP contact lenses for the effects of visual acuity and cornea on subjects with abnormal refraction status. One hundred twenty one adults (twenty nine males, ninety two females, range = 17 to 43, mean = 22.86) were recorded. The subject's history including, the symptoms from previous lens wear, were studied. The subjects were observed, both pre and post lens wear, for any symptoms and signs of change of the eye. The Visual acuity and the binocular status were tested at the far distance using the contact lens. The refraction test was performed on the naked eye using the objective method (Topcon KR-8100, Japan). The Stereopsis test was performed at the near distance after contact lens wear by the Titmus fly (Stereo Optical Co., U.S.A) and TNO (TECH, The netherlands). The contrast sensitivity diagnosis was performed at 1m distance after contact lens wear by the contrast sensitivity chart (pelli-Robertson, USA). The corneal topography was analyzed on the naked eye after lens wear by ORB scan (Bausch Lomb, U.S.A.). The ultra structure of surface on the contact lens was observed using SEM (JMS-5800, Japan). The chemical component's of the contact lens was analyzed by EDS program. The results of this study were as follows: 1. The longer of contact lens wear period, The subjects have acquired the most improved visual function. 2. Subjects had experienced few side effects wearing the contact lenses. 3. The lenses were easy to use by the subjects. 4. The longer of contact lens wear period, the power of cornea had more decrease. but the base curve of cornea had more increase and corneal astigmatism was decrease (p<0.01). Also, the thickness of corneal center was few decrease. 5. Longer periods of using the contact lens showed stereopsis and contrast sensitivity at more normal values. 6 The corneal topographical after lens wear showed most subjects with similar morphology for different wear periods. 7. The surface ultrastructure of the new and used contact lens was the similar fine shape. 8. The chemical component's of in the new and used contact appeared to have similar results. In conclusion, this study showed that the surface ultrastructure and chemical component's of the new and used contact lens are similar. In addition, the subjects had improved the quality of vision and few experienced any side effects during long periods of contact lens wear. Also they have decrease of corneal astigmatism during the long period of lens wear. Our test has showed that the chemical composition and fine structure of contact lens have related to the visual function on contact lens wearer. In this paper, we suggested that ez NANOsence II RGP contact lenses had a moderate effect for correcting vision of abnormal refraction eye.
