  • This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

  • Purpose : To evaluate the effects hip abductor strengthening exercise using elastic band on static balance. Methods : The subjects consisted of twenty healthy people. The subjects were divided into two group. The control group(n=10) received no exercise and/or stimulation. The elastic band strengthening exercise(E/E) group(n=10) performed hip abductor for strengthening exercise using elastic band. E/E group were accomplished during 6weeks(3day/week, 30-40min/day). All tests were completed before and after experiment. The static balance ability was measured by normal standing when eye open and close on GOOD BALANCE System, respectively. For each case, the experimental data were obtained in 3 items: mean X speed, mean Y speed and velocity moment. Results : The results of this study were as follows; 1. In E/E group, the statistically significants were shown on Y speed and velocity moment in the case of normal standing when eye open and X speed and velocity moment in the case of normal standing when eye close(p<0.05). 2. In control group, the statistically significants were not shown on all posture(p>0.05). 3. There was a statistically significant difference on the X speed and velocity moment in the case of normal standing when eye close between control group and E/E group(p<0.05). Conclusion : The above results revealed that hip abductor strengthening exercise using elastic band were partly effective for improving the static balance ability.

  • A new physiotherapy named Ciliary Muscle Training method and one successful case had been reported first for treatment of Posner-Schlossman Syndrome (PSS), also known as Glaucomatocyclitic Crisis. When a person observed a back and forth moving object, the ciliary muscle would involuntarily do sometimes tense and sometimes relaxant exercise which can relieve the tensive state of the ciliary muscle of patients suffering PSS disease. Through this period of continued treatment, this ciliary muscle training method can improve the health status of the ciliary muscle and finally achieve the purpose of curing PSS disease. In this successful case, the patient's feedback result was very good after receiving our suggested ciliary muscle training method as an attempt to treat PSS, ill right eye of this PSS patient showed normal appearance without any differences from the other normal eye, his vision test values of naked eye were both 4.9 under nearly 200 degrees of myopia. High intraocular pressure (IOP) was mitigated, measured IOP value was in the normal (≦ 21 mmHg) and comfortable state without PSS relapse until now. Therefore, ciliary muscle training method could be a potential clinical treatment approach to PSS disease.

  • This report described a severe bilateral microphthalmia in a young Holstein calf. The anomalous calf with wry tail showed normal vigor, appetite and normal body weight except for eye defect. The orbits were shallower and smaller than normal. The orbit bilaterally contained a white small mass suspected as eyeball. A spot-like remnant of eyeball (REB) was buried in the mixture of vestigial extraocular muscles and adipose tissue of the bilateral orbit. Histologically, the REB was composed of irregularly arranged elements of ocular wall such as sclera, retina and ciliary body. But any destructive changes in the central nervous systems were not detected. This case of eye defect was defined as severe bilateral microphthalmia. The cause of this ocular defect is unknown.

  • Objectives The purpose of this study was to examine the effects muscle fatigue at the knee muscles on balance during standing in healthy adults. Methods Thirty healthy adults were recruited along with their written informed consent. Subjects were randomly assigned to knee extensor group (fatigue on knee extensor, KE), and knee flexor group (fatigue on knee flexor, KF). And subjects performed exercise with each muscle group until muscle fatigue was induced. They were assessed balance ability by functional reaching test (FRT), limit of stability (LOS), and postural sway (one leg standing, normal eye open (NO), normal eye close (NC), pillow with eye open (FO), and pillow with eye close (FC)) before and after fatigue. Results There were significant group differences balance performances in FRT, anterior of limit of stability, one leg standing, and the muscle fatigue of knee muscles were decreased balance performances. The balance performance was affected by visual sense and proprioception. Conclusions These results show that the muscle fatigue of knee muscles decreased balance performance. Therefore, balance exercise program should be trained without muscle fatigue.

  • The patients with myotonic dystrophy (MD) show ocular motor abnormalities including strabismus, vergence deficits, and inaccurate or slow saccades. Two theories have been proposed to explain the oculomotor deficits in MD. The central theory attributes the defects of eye movements of MD to the involvement of the central nervous system while the muscular theory attributes to dystrophic changes of the extraocular muscles. A 58-year-old woman with MD showed selective slowing of horizontal saccades and reduced peak velocities for both horizontal canals in head impulse tests, while smooth-pursuit eye movements and vertical head impulse responses were normal. This case suggests that the extraocular muscles-as a final common pathway of the voluntary saccade and reflexive vestibular eye movements-may better explain the defective rapid eye movements observed in MD.

  • Inherited metabolic disorders (IMD) are a large group of rare disorders affecting normal biochemical pathways. The ophthalmic involvement can be very varied affecting any part of the eye, including abnormalities of cornea, lens dislocation and cataracts, retina and the optic nerve, and extraocular muscles. Eye disorders can be initial symptoms of some IMD and can be clue for diagnosis of IMD. However, eye disorders can evolve later in the natural history of an already diagnosed metabolic disorder. Awareness of IMDs is important to facilitate early diagnosis and in some cases instigate early treatment if a patient presents with eye involvement suggestive of a metabolic disorder. Ophthalmological interventions are also an important component of the multisystem holistic approach to treating patients with metabolic disorders.

  • In order to provide data of effective health education for practice of preventive health behavior for visual acuity care. The authors investgated the actual acuity and health behavior for visual acuity care. The subjects of this study were 2250 students in high school. The data were collected by questionnaire developed for the purpose of this study which has been made through references and student's health record. The results were as follows, 1) As students move up to grade, the number of students with decreased visual acuity had a tendency to increase. In cases with decreased visual acuity below 0.2 in one or both eye, the number of cases was increased in accordance with moving up to grade, especially visual acuity of right eye was more decreased than that of left eye. 2) As to proportion of the group with decreased visual acuity among the total students, among 2250 students, students with decreased visual acuity was 35.6%(800 students). According to school type, in academic school, frequency of students with decreased visual acuity in day school was higher then that in night school. In commercial school, the frequency of students who had decreased visual acuity in night school were higher than that of students in day school. 3) As to variables influencing the decreased visual activity, there was a significant different between groups with normal visual acuity and groups with subnormal in terms of awareness of visual acuity by themself, parent's visual acuity, unbalanced eating habit, distance from television, or books, posture in watching television, posture in reading, awareness of illumination in classroom. 4) As to practice of protective and preventive health behavior for visual acuity care, In group with normal visual acuity. There was good practice such as proper eating habit, proper studying habit, and health habit in its descending order, but proper illumination and regular eye test were practiced poorly. In group with subnormal visual acuity, one of the vest practice in visual acuity care was an effort to prevent eye strain. Other good practice involve tasking regular eye test, maintaining proper studing habit, in its descending order.

  • A face recognition algorithm for the user identification procedure of automatic teller machine(ATM), as an application of the still image processing techniques is proposed in this paper. In the proposed algorithm, face recognition techniques, especially, face region detection, eye and mouth detection schemes, which can distinguish abnormal faces from normal faces, are proposed. We define normal face, which is acceptable, as a face without sunglasses or a mask, and abnormal face, which is non-acceptable, as that wearing both, or either one of them. The proposed face recognition algorithm is composed of three stages: the face region detection stage, the preprocessing stage for facial feature detection and the eye and mouth detection stage. Experimental results show that the proposed algorithm can distinguish abnormal faces from normal faces accurately from restrictive sample images.

  • Purpose: The study was performed to compare the difference of non-invasive tear break-up time (NIBUT) with alignment or steep fitting of soft contact lens in normal and dry eyes. Methods: Total 40 eyes (aged 20~30 years) were classified to the normal (n=20) or dry eye group (n=20) by the diagnosis methods for dry eyes and worn soft contact lens (polymacon material) with alignment or steep fitting. NIBUTs of lens wearers were separately measured at the points of before wearing, immediately after wearing and after stabilization of tear film. Results: With alignment fitting, averaged NIBUT in the dry eye group after stabilization of tear film was not significantly different from that of the normal eye group. However, averaged NIBUTs in the normal and dry eyes had significant difference when measured immediately after lens wearing. However, the number of eyes having NIBUT less than 4.0 second was 30% higher compared to the number of normal eyes with steep fitting when measured immediately after wearing. Some shorten NIBUT in dry eyes with steep fitting was also shown after stabilization of tear film. Conclusions: These results suggest that wearing soft contact lens in dry eyes differently affect tear film compared to normal eyes. Thus, dry eyes need more advertent fitting for contact lens wearing because of unstable tear film.
