Objectives and methods: We investigated 17 books to study symptoms, pathology and acupuncture & moxibustion treatment of Hu-Ro(fatigue). Results and Conclusions: 1. The symptoms of Hu-Ro are the deafness, the amblyopia, the mass of sweat, the stiff joint, etc. There are also symptoms such as the fever of palm and legs, avoiding cold temperature in the afternoon, the fever during night time, the stomach fullness and diarrhea, the powerlessness of limbs, red colored urine. 3. The representing pathological mechanisms of Hu-Ro are Yang-deficiency(陽虛), Yin-deficiency(陰虛), Energy(Qi)-deficiency(氣虛), Blood(Hyul)-deficiency(血虛). The other pathological mechanisms are deficiency of Liver, Heart, Spleen, Lung, Kidney and the basic Energy. 4. The fundamental treatment of Hu-Ro is "warming on worned ones(勞者溫之), supplying on damaged ones(損者益之), strengthening the weakened ones(虛卽補之)" as basis and also supplying blood with fostering spleen(養血建脾) and droping fever with clearing the clogged(降火淸鬱). 5. The meridians that could be used in acupuncture and moxibustion treatment application of Hu-Ro are the urinary bladder meridian, the conception vessel meridian(任脈), governor channel meridian(督脈), kidney meridian(腎經), liver meridian, heart meridian, spleen meridian, lung meridian, stomach meridian, small intestine meridian, gall bladder meridian, pericardium meridian and triple-warmer meridian in order of frequently refered. 6. The meridian points that could be used in acupuncture and moxibustion treatment application of Hu-Ro are Joksamni (足三里:25times), Sinsu(腎兪:20回), Bisu(脾兪:19回), Pyesu(肺兪:18回), Qihye(氣海:17回), Gohwang(膏肓:15回), Kwanwon(關元:14回), Sameumgyo(三陰交:13回), Eumgeuk(陰郄:12回), Daechu(大樞:12回), Sinmun(神門:11回), Simsu(心兪:11回), Nyegwan(內關:10回), Jungwan(中脘:10回) in order of frequently refered.

This research was performed to screen eye health status for pre-school children (4~5 age) and establish as eye health checking system m community health center. This data was collected from 1st February, 1995 to 31st October, 1995. To screen the state of their vision, the Developed Visuual Test (D.V.T) was used for pre-school children. This is used at home by their parents and then it is also used among the kindergarten health team at Jung-gu health center in Seoul. This was done with the and of Randot and Han Choun Souk tests. The total number of children who were tested was 1441. Among the children, children aged 5 were 707, and those aged 4 were 734. The results of this study were as follows; * Description of the health status for the pre-school children. 1. The rate of children average vision in both eyes, whose was below 05 by Han Choun Souk are 7.6% (age 4) and 4.8% (age 5). 2. Only 20 4% (age 5) and 30 8% (age 4) of the pre-school children had been tested through the ophthalmic department. 3. The children with a level below 05 (Han Choun Souk test) had been tested only 43% (age 4), and 12% (age 5) 4. There was no particular difficulty in understanding the D.Y.T: 13.9% (age 4), 11.6% (age 5) of the tested children had eye problems. 5. 231 cases were trichiasis, entropin, strabismus, and amblyopia. * The different visual tests. The results of the visual tests between the two groups (parents and health teams) are similar and it shows that parents can easily test at home. * Delivery system of the D.V.T questionnaire The way children's parents received the D.V.T questionnaire were carried out by two ways By mall from the community health center. Send through the institution, for example the kindergarten school The receipt rate of this D.V.T questionnaire sent through the institution was higher than sent by mall.

Xu-lao(虛勞) is deficient disease which is weak body and spirit. It occurs many symptoms, for example lack of appetite, dizziness, involuntary emission of semen, wet dream, back and chest pain, night sweat, cough and so on. In oriental medicine, xu-lao(虛勞) is well-known disease and can be treated easily. In general, xu-lao (虛勞) patiences like to be treated by oriental medical doctors. In spite of improving food, house and clothes, xu-lao(虛勞) is on the increase by fatty foods and stress. In most of these cases, the cooperations of heart and kidney are hurted. On Fang-you-ge-bian(脈證方藥合編) which is the famous prescription book in Korea, gu-an-xin-shen-wan(古庵心腎丸) and Jiu-yuan-xin-shen-wan(究原心腎丸) are used well and have good effects in these cases. Gu-an-xin-shen-wan(古庵心腎丸) can treat white hair, palpitation, involuntary emission of semen, amblyopia, buzzing in the ears, backache and so on. Jiu-yuan-xin-shen-wan(究原心腎丸) can treat lack of appetite, dizziness, involuntary emission of semen, wet dream, back and chest pain, diseased sweat, cough, coldness of hands and feet, and so on. The symptoms of Gu-an-xin-shen-wan(古庵心腎丸) are similar with those of Jiu-yuan-xin-shen-wan(究原心腎丸). But, it is very important that Gu-an-xin-shen-wan(古庵心腎丸) can be used in cases of hot deficient disease but Jiu-yuan-xin-shen-wan(究原心腎丸) can be used in cases of cold deficient disease.

Purpose. We wanted to find out how the changes in brain function affected by the beats per minute (BPM) of music affected visual function. Methods. The subjects were 40 people in their 20s (30 men, 10 women) with no eye disease, strabismus, amblyopia and a corrected visual acuity of 1.0 or higher. Wearing headphones while excluding surrounding noise as much as possible, we played music while adjusting the beat rate at 40 BPM intervals from 80 to 200 BPM. Then, pupil size measurement, lag of accommodation test, and minus lens addition method maximum accommodation test were performed and analyzed. Results. As a result of analyzing changes in visual function according to beats per minute [BPM], it was found that although sound can be consciously affected, it does not directly affect visual function significantly in terms of accommodative lag and changes in pupil size. It was confirmed that the effect was limited to the maximum accommodation. Conclusions. In clinical practice, it is necessary to conduct a refraction test while keeping in mind that there are changes in visual function depending on the BPM of surrounding sounds.

Purpose: Stereopsis is one of primary characteristics for assessment of binocular function. The purpose of this study was to determine the possible relationship between the degree of exophoria and stereoacuity at near. Methods: 110 exophores (male n=71, female n=39, mean $age{\pm}SD=11.30{\pm}1.47$ years) without amblyopia, strabismus, and ocular and systemic pathology were studied. Subjects were also excluded if they had visual acuity poorer than 0.8 in either eye or vertical phoria greater than 1 prism diopter. Clinical tests were performed for near phorias by von Graefe technique using a Digital Refractor (CDR-3100, Huvitz, Korea) with chart (Predio CDC-4000, Huvitz, Korea), and for stereoacuity using the Titmus fly. Results: A one-way analysis of variance revealed that mean values of the stereoacuity classified according to the degrees of the exophoria were not significantly different (p>0.05). Conclusions: Based on the result of this study, it was found that there was no relationship between the degree of exophoria and stereoacuity.

To 160 persons(90 men, 70 women) who went to the national hospital of Solok-island with Hansens's disease, I tested the objective refracts test with the product of Cannon Ltd. Co. which RK-3 Auto Ref-keratometer's auto ophthalmoscope. The results were like these. Visual acuity of above 0.7 that can live without glasses was contained 44 men's eyes(24.4%) and 19 women s eyes(13.6%). These result are indicated that men have had more good visual acuity than women. Visual acuity of below 0.6 that cannot do normal life was contained 80.3% of the total patients. And amblyopia of below 0.3 and eyes which cannot be corrected were shown 44.4%(80 men's eyes and 55.7% 78 woman's eyes). Myopia was contained 119 eyes(43), hyperopia was contained 139 eyes (50.4%) and emmetropia was 6.5%. Astigmatism was shown 136 men s eyes (86.6%) and 97 women's eyes(81.5%). These results are indicated what many people accompany with astigmatism. And these ratio had some high percentages men rather than women. Direct astigmatic was contained 37 eyes (11.6%), Indirect astigmatic 81 eyes(25.3%) and Oblique Astigmatic 115 eyes(35.9%). As a of distributed result oblique astigmatic occupied best high point as 49.4% in 233 astigmatism and distributed the opposite direction as compared with normal irregular emmetropia not patient.

117 undergraduate ophthalmic optics students volunteered to participate in this study. They ranged in age from 19 to 26 years. Subject, had best corrected visual acuity of at least 1.0 in both eyes, no strabismus, no amblyopia, and no history of ocular surgery. 37 subjects are esphoria and 25 subjects are $3{\Delta}$ and less, and the rest of 12 subjects show more $4{\Delta}$. Average phoria amount is $2.96{\Delta}$ at far distance and $1.08{\Delta}$ at near distance, respectively. The variation of phoria amount in far and near distance, unchanging subjects are 3, 8 subjects are increase esophoria amount, and 26 subjects are phoria amount decreasing or appear exophoria. The reason of esophoria amount is decreasing in near distance, and the results are convergence burden decreases. At positive relative convergence, the expected value in far distance, blurred point is 7, break point is 16, and recovery point is 12. And negative relative convergence, break point is 7 and recovery point is 13, respectively. Moreover, at positive relative convergence, the expected value in near distance is blurred point is 8, break point is 7 and recovery point is 22. And negative relative convergence, blurred point is 2, break point is 8 and recovery point is 12, respectively.

Purpose: This study was performed to investigate the difference of meridional visual acuity and the loss of corrected visual acuity (VA) in order to emphasis the importance of astigmatic correction. Methods: 64 subjects (122 eyes) aged $22.75{\pm}2.36years$ participated in this study. After full correction of astigmatic refractive error, VA was measured in which the direction of the slit filter was matched with astigmatic axis and $90^{\circ}$ to the astigmatic axis. Results: 52 eyes showed no difference in VA between the two direction. However 70 eyes had difference VA between them. 14 out of 52 eyes and 24 out of 70 eyes had under 1.0 in monocular VA. The astigmatic degree was higher in the existence of VA difference between the two direction than non-existence. The difference is higher with under 1.0 monocular VA. Monocular VA is closely related to the focal line having better VA in the principal focal line. Glasses replacement period was analyzed as 6~12 months for the preservation of better VA. Conclusions: The final glasses prescription has to be given with full correction because continued under-correction for astigmatism causes meridional VA difference.

Purpose: The aim of this study was to compare binocular functions such as near point of convergence (NPC), AC/A ratios, heterophoria, accommodation, accommodation lag, positive relative accommodation (PRA), negative relative accommodation (NRA), positive relative convergence (PRC), negative relative convergence (NRC) in normal subjects and convergence insufficiency. Methods: 86 subject (male n=45, female n=41, mean $age{\pm}SD=23.27{\pm}2.85$ years) without amblyopia, strabismus, and ocular pathology were studied. Forty three patients each group were classified as normal subjects and convergence insufficiency group based on AC/A ratio and far and near phoria. Binocular function of the two groups was measured using phoropter. r. Results: The values between normal subjects and convergence insufficiency were 5.71 cm and 7.07 cm for NPC, 5.28 and 2.81 for Heterophria AC/A, 0.92 exo/3.36 exo and 2.17 exo/10.84 exo for far and near phoria, 15.49/23.30/13.30 and 13.50/20.02/9.09 for PRC, respectively. However, there were no significant differences between normal subjects and convergence insufficiency for accommodative amplitude, accommodative lag, PRA, NRA, BI vergence test, BO vergence test, NRC. Conclusions: Both groups were a significant difference for cover test, NPC, Heterophria AC/A, far and near phoria, break point of PRC, and recovery point of PRC.

Purpose: The aim of this study was to explore the effect of artificially decreased eye in normal vision on eye-hand coordination (EHC) when using the Lee-Ryan Eye-Hand Coordination Test recently reported. Methods: Eleven adults with normal vision aged $29.46{\pm}5.94$ years participated for this study where a non-dominant eye artificially induced moderate refractive amblyopic vision at near by adding a plus lens conducted EHC tasks and then did the test again under normal vision following 2 weeks. To investigate the ability of EHC, 7 tasks including individually different level of difficulty in the Lee-Ryan EHC Test were selected to compare and analyze EHC in terms of two independent variables such as time taken and the number of errors. Results: In time taken, subjects with artificially decreased vision took more time than normal vision under monocular conditions (p=0.013), while those with the decreased vision completed their tasks faster than normal vision under binocular conditions (p=0.001). In the number of errors, subjects with the decreased vision made more mistakes (p<0.001) as shown in time taken, whereas there was no difference between monocular and binocular viewing conditions in the decreased vision. Conclusions: Unlike previous EHC tests including limitations for application, deficit in EHC can be screened by the Lee-Ryan EHC Test developed based on simple computer-based system. Therefore, it is considered that further studies relevant to deficits in visual function such as amblyopia will be carried out in clinics as well as research.
