1.Postmortem Change of Adhesive Forces Between the Retina and the Retinal Pigment Epithelium.
Journal of the Korean Ophthalmological Society 1993;34(2):111-116
Adhesive forces between the retina and the retinal pigment epithelium, which is mainta ined by active mechanisms unique for living animals, deteriorates rapidly after death and leads to spontaneous retinal detachment. Change of retinal adhesiveness in rabbits after death was investigated using a new method. Retinal detachment was induced by applying various levels of aspiration power from 0 to 1OO mmHg to the vitreous cavity using a vitrectomy instrument immediately after the rabbit was killed without enucleation. And the time required for creating the retinal detachment was measured. Retinal adhesiveness deteriorated and spontaneous retinal detachment occurred 28 minutes and 35 seconds after death confirming the active adhesion between the retina and the retinal pigment epithelium before death Increase of aspiration power led to shortening of time required for creating retinal detachment. From aspiration powers of 0 to 100 mmHg, the common logarithm of time required for retinal detachment was inversely proportional to the aspiration power [IogY = 1.45215 - 0.01113X, (R2=0.99041), X: aspiration power (mmHg), Y: time required for creating retinal detachment (minutes)]. Thus, presumed time of retinal detachment could be estimated between the aspiration powers of 0 to 100 mmHg.

2.Factors Influencing Perceived Health Status and Life Satisfaction in Rural Residents.
Journal of Agricultural Medicine & Community Health 2012;37(3):145-155
OBJECTIVES: This study was performed to compare rural residents' perceived health status and life satisfaction according to their general and health related characteristics and to identify factors related to perceived health status and life satisfaction in this population. METHODS: Subjects were 1,091 adults aged 20 years or older living in Geochang Gun, South Korea. A survey was conducted from June 28 to August 25, 2009. We used the health self rating scale by Lawton et al. (1982) and the overall life satisfaction scale by Wrosch et al. (2000). The collected data were analyzed using SPSS WIN 18.0. RESULT: Sex, age, education, spouse, medical diagnosis, currently taking medication, main health maintenance behavior, alcohol consumption, frequency of alcohol consumption, exercise, family harmony, and friend relationships were significantly related to perceived health status. Age, education, spouse, main health maintenance behavior, smoking, exercise, family harmony, and friend relationships were significantly related to life satisfaction. Further, 29.3% of the variance in perceived health status could be explained by medical diagnosis, exercise, family harmony, education, currently taking medication, and friend relationships, while 11.1% of the variance in life satisfaction could be explained by family harmony, perceived health status, main health maintenance behavior, and friend relationships. CONCLUSION: Health management programs must be designed so as to incorporate the general and health related characteristics of rural residents if they aim to improve the perceived health status and life satisfaction in that population.

PURPOSE: The purpose of this study is to identity the effects of a tailored health promotion program on rural residents' self efficacy, health problems and quality of life. METHOD: Data were collected from May 13th, 2006 to July 29th, 2006. The subjects were selected at Gajo-myeon, Geochang-gun, Gyeonsangbuk-do, Korea. Forty three residents were included in the experimental group and 39 in the control group. The 12-week health promotion program was given to the experimental group. Data were analyzed by descriptive statistics, chi2-test, t-test and ANCOVA test with the SPSS/Win 12.0 program. RESULT: The experimental group showed higher scores of self efficacy and quality of life than the control group, and a lower score of health problem than the control group. CONCLUSION: From the above results, it can be concluded that the tailored health promotion program for rural residents is an effective intervention for improving their self efficacy and quality of life and reducing their health problems. Therefore, it is necessary to spread the tailored health promotion program for residents in other rural areas in Korea.

5.A Case of Multiple Intracranial Hemorrhage Associated with Enoxaparin Treatment for an Acute Myocardial Infarction after Resuscitation.
Journal of the Korean Society of Emergency Medicine 2008;19(2):211-216
We report a rare case of multiple intracerebral hemorrhage, subarachnoid hemorrhage, and intraventricular hemorrhage that developed after successful cardiopulmonary resuscitation (CPR). A 66-year-old man underwent CPR for about 10 minutes in his community hospital. At that time, his only sequela was ST depression in leads V3, and V4 with an ECG. There was no definite parenchymal lesion in the brain computed tomography (CT) scan taken in the community hospital, and the patient was transferred to Wonju christian hospital for post-resuscitation management. Upon arrival, echocardiographic findings showed akinesia of the anterior wall and anteroseptal wall together with decreased ejection fraction (34%). A cardiac enzyme assay showed a CK-MB concentration of 19.4 ng/ml and a troponin-I level of 1.66 ng/ml. He was mentally comatose and both pupils were isocoric and reflexive to light. We concluded that the cause of cardiac arrest was acute myocardial infarction (AMI), and the patient was treated with drugs including aspirin, clopidogrel, enoxaparin-sodium (1 mg/kg subcutaneous), and isosorbide dinitrate. At 10 hours after admission, a follow-up ECG showed ST elevation in lead I, aVL and all leads from V1 to V6. Right anisocoria was seen in neurologic examination at that time. A subsequent brain CT revealed multiple intracerebral hemorrhage, subarachnoid hemorrhage into all cisternal spaces, and intraventricular hemorrhage. Clotting evaluations yielded a prothrombin time (PT) of 14.6 sec., partial thromboplastin time (PTT) of 45.3 sec. and an INR of 1.32, and a hemoglobin count of 16.2 g/dL.

BACKGROUND: There are many rating scales for assessment of geriatrics. But each of these scales were not sufficient to evaluate comprehensive geriatric assessment, physical and psychologic efforts for care. METHODS: We developed new scales to comprehensive geriatric assessment for care of geriatric patients. The Geriatrics Physical Support Scale(GPSS) evaluates physical effort consists of 10 areas and the Geriatrics Global Support Scale(GGSS) evaluates general condition of patients consist of 6 areas. Eighty probable and possible AD patients received the Clinical Dementia Rating Rating Scale(CDR), Korearn version of Mini-Mental State Examination(K-MMSE), Barthel Activity of Daily Living Index(B-ADL) GPSS, GGSS. We tested internal consistency, correlation among dementia rating scales. RESULTS: The GPSS correlated to CDR -0.63(p<0.01), B-ADL -0.90(p<0.01) and the GGSS correlated to CDR -0.60(p<0.01), B-ADL -0.75(p<0.01). The internal consistency were 0.69(GGSS), 0.92(GPSS). CONCLUSION: The Geriatrics Global Support Scale evaluate general condition of patients and the Geriatrics Physical Support Scale evaluate physical efforts needed for care of geriatric patients. These scales an also brief and easy rating scales to grade degree of caregiver`s burden.

Journal of Agricultural Medicine & Community Health 2009;34(1):47-57
OBJECTIVES: The purpose of this study was to identify the health promotion behavior, health problem, perceived health status and farmers' syndrome of rural residents. METHODS: The subjects of this study were 637 adults of 19 primary health care post extracted from 1.875 primary health care post in Korea by quota sampling method. The collected data were analyzed by descriptive statistics, Pearson's correlation. RESULTS: The average score of health promotion behavior was 2.23. In the sub-scales, the highest degree of performance was 'nutrition', followed by 'spiritual growth' and the lowest degree of performance was 'physical activity'. The most prevalent health problem was ailments in 'musculoskeletal system', followed by 'fatigue', 'eyes and ears', 'cardiovascular system'. The mean score of perceived health status was 8.54. The prevalence of farmers' syndrome was 98.4%. Health promotion behavior showed a significant positive correlation health status and perceived health status showed a significant negative farmers' syndrome. CONCLUSIONS: With the above findings, rural residents' physical activity is less than urban residents', and the rural resident's score of perceived health status, musculoskeletal system and fatigue are lower than urban residents'. The farmers' syndrome of the rural people is high. A tailored health promotion program for rural community is needed to develop in the consideration of these findings.

Journal of the Korean Academy of Rehabilitation Medicine 1999;23(3):609-614
OBJECTIVE: To determine whether ankle plantar flexors stretching exercise affects functional reach in elderly men. METHOD: Twenty elderly men with an average age of 78.2 years were selected for this study. A active range of motion of ankle dorsiflexion and a functional reach (FR) distance were measured before and after ankle stretching exercise. The ankle dorsiflexion was measured by goniometer in knee extended position. The FR distance was measured in standing position. Ankle plantar flexors stretching exercises were carried out by physical therapist 4 times per week for 4 weeks. At 4 weeks after the stretching exercise, we retested the active range of motion of ankle dorsiflexion and the FR distance using the same method. RESULTS: At 4 weeks after the stretching exercise, the active range of motion of right ankle dorsiflexion was increased from 2.81 +/- 3.26degrees to 5.98 +/- 4.34degrees, and the left ankle dorsiflexion was increased from 3.15 +/- 3.77degrees to 6.35 +/- 2.45degrees. The FR distance was increased form 12.22 +/- 7.54 cm to 19.69 +/- 8.59 cm after the stretching exercise. CONCLUSION: The FR distance was significantly increased after the ankle plantar flexors stretching exercise (p<0.01). This results suggest that the ankle plantar flexors stretching excercise may be capable of increasing the FR distance in elderly.

10.Effects of Muscle Fatigue on Knee Proprioception.
Journal of the Korean Academy of Rehabilitation Medicine 1998;22(4):960-965
OBJECTIVE: To determine whether muscle fatigue affects knee joint proprioception. METHOD: Thirty healthy subjects (18 male and 12 female) with an average age of 22.1 years were selected for this study. Angular errors were measured to test propriocetive function in the knee joint. In a sitting position, the subject's dominant leg was passively positioned to the 45degrees knee flexion stimulus point for 2~4 second, while the subject concentrated on this position, the leg was passively returned to the 90o flexion position, afterward the subject was asked to duplicate the stimulus point actively. The difference, in degrees between the stimulus point and the reproduced point is an angular error. All subjects were blindfolded and underwent proprioception measurement before and after the muscle fatigue. Isokinetic exercises performed at 180 degree/sec on the Cybex Orthotron II(Cybex, a division of Lumex, Inc. USA) were used to induce the muscle fatigue. All subjects performed an isokinetic exercise with their dominant leg. Exercise was continued until 50% of the initial peak torque was reached. When the subjects were fatigued to less than 50% of the initial peak torque, the isokinetic exercises were discontinued. Then we immediately retested the proprioception using the same method. RESULTS: The mean and standard deviation of the angular error increased from 2.79+/-1.17degrees to 6.40+/-3.42degrees after muscle fatigue. CONCLUSION: The proprioception significantly decreased after the muscle fatigue(p<0.001). This result suggests that the muscle fatigue must be considered when an injured professional athlete a patient with fatigable disease is set in a rehabilitation program. Further studies are required to determine the physiological mechanisms of the role of muscle fatigue for the decreasing proprioception.
