Development of a model system for mode of action studies of SO_2 was attempted with a plant tissue. Leaf disks, 1.0㎝ diameter, cut from the lamina of lettuce leaves, were floated on the testing medium and placed in light or dark condition to investigate the discoloration pattern with various sources of SO_2. Discoloration of leaf disks tended to be more serious with higher concentrations of SO_2 and on exposure to the light. Leaf disks were more severely discolored at lower pH with constant SO_2 concentration. These discoloration patterns were highly reproducible and similar in all sources of SO_2. Spectrophotometric evidence suggested that light-mediated discoloration of leaf disks in the presence of SO_2 might occur mainly through chlorophyll α degradation.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

Growth responses of lettuce seeds germinated in aqueous solutions of SO_2 were investigated for mode of action studies of this gas. The concentration and pH of SO_2 solution greatly affected the growth of germinating seeds. Root growth was more sensitive to SO_2 than hypocotyl growth. The sensitivity of total seedling growth lay between root and hypocotyl growth. Growth inhibition of germinating seeds appeared more serious when SO_2 was added during the early stage of germination.

To find the characteristics of stroke patients and the relation between the pathway of admission and characteristics, of the patients including general characteristics, progression of disease and subjective complaints, an analysis was made from the medical record of 291 inpatients due to stroke admitted to a oriental medicine university hospital in 1997. 1. Diagnosis categories of analyzed Patients were 50 cerebral hemorrhage and cerebral infarction. 2. Sex distribution of patients showed 125 male and 165 female and age distribution showed peak 33.7% at 60-69 year old group, 26.5% at 70-79 year old group in descending order(p<05). 3. Thirty four percent of stroke patients had family history of stroke and male showed significantly higher rate of family history of than female(p<05). 4. The type of physical constitution was classified as Tea-Eum-In(太陰人) 43,6%, So-Eum-In(少陰人) 29.9%, So-Yang-In(少陽人) 26.1%, Tea-Yang-In(太陽人) 0.3% in descending order of frequency. 5. Hypertension was the preceding condition for 36.4% of cerebral hemorrhage and 42.7% of cerebral infarction. 6. Sixty nine point four percent of the patients of the patients suffered from the stroke for the first time and 25.4% for the recurred stroke. Major subjective complaints of the patients were motor disturbance, speech difficulty and headache in descending order. 7. As the institution for medical care to this admission, 138 person(47.4%) used western type hospital or clinics, 137 persons(47.1%) passed oriental medicine clinics or hospitals, 6 persons(2.1%) used both type of western medicine and oriental medicine and 10 person(3.4%) used pharmacy folk medicine. 8. As pathway of medical care for cerebral hemorrhage 71.2% of patients used western type hospital or clinic and 26.9% used oriental type of care where as for cerebral infarction 42.3% used western type and 51.5% used oriental type. 9. While admitted to this hospital within one day after occurrence of the disease used oriental type by 87.5% and western type by 14.3%, patient admitted in one week after occurrence of the disease used western type by 66.9% and oriental type by 27.1%. The above results showed that the pathway of medical care for the stroke patients was complicated and make many problems due to delay in the arrival to medical care. So effective health care delivery system for the stroke patients must be made for more efficient medical care.

Recently, special attention has been given to acid rain and its problem to environment such as acid precipitation and air pollution in East Asia. In the present study, rainwater samples were collected from Apr to Nov in 2012. The samples were chemically characterized for the assessment of emission sources. Suwon and Yeoju regions, typical agricultural areas in South Korea, were chosen for study sites. Ion composition and cation-affected neutralization were determined to evaluate the contribution of cations to the acidity of rainwater. Ion and electrical conductivity between the measured and the estimated showed high correlation. The cations observed in Suwon and Yeoju were Na<SUP>+</SUP> > NH4<SUP>+</SUP> > K<SUP>+</SUP> > Ca<SUP>2+</SUP> > Mg<SUP>2+</SUP> > H<SUP>+</SUP> and Na<SUP>+</SUP> > K<SUP>+</SUP> > NH4<SUP>+</SUP> > Ca<SUP>2+</SUP> > Mg<SUP>2+</SUP> = H<SUP>+</SUP>, respectively. The anions of all sites were SO4<SUP>2-</SUP> > NO3- > Cl<SUP>-</SUP>. While the amounts of sulfate, one of the major dissolved components of rainwater, were 77.6 and 75.6 ueq L<SUP>-1</SUP> in Suwon and Yeoju, the ones of NSS-SO4<SUP>2-</SUP> (Non-Sea Salt sulfate) were 83 and 82% in Suwon and Yeoju, respectively. The comparison of observed pH values (pHobs) with the theoretical pH values (pHthe) showed that the neutralization of rain water considerably went along during the study periods. The highest amounts of rainfall throughout the year in Suwon and Yeoju were 572.3 and 484.6 mm in July, and its corresponding nitrogen loadings in Suwon and Yeoju were 5.28 and 3.50 kg ha-1, respectively. The major ion contents for crop growth with SO4<SUP>2-</SUP>, Ca<SUP>2+</SUP>, K<SUP>+</SUP> and Mg<SUP>2+</SUP> were 51.7, 5.2, 11.8 and 1.8 kg ha<SUP>-1</SUP> in Suwon and 34.2, 4.0, 4.2 and 1.1 kg ha<SUP>-1</SUP> in Yeoju.

A structure is an assemblage of members that should be fastened. High strength bolts have been frequently used to make structural connections. When a load is applied on a line of action that does not pass through the centroid of a bolt group, there will be an eccentric shear effect on the bolt group. In this study, a fastener which consists of 6 bolts was fabricated, and a jig was designed to produce variable eccentricities. Loads were applied to the fasteners by UTM until failure, and the maximum load capacity that the fastener can sustain was measured. Together with the experiments two theoretical approaches were used to predic t the load capacity, one is the elastic analysis and the other the plastic analysis. An expression was proposed for the load versus deformation response of the bolt material, and the secant method was used to get a numerical solution for the non-linear plastic analysis. Test results showed that the load capacity of a fastener for the plastic analysis was higher than that for the elastic analysis, and the load capacity for the plastic analysis was closer to the experimental one.

Spasticity has been defined as "a motor disorder characterized by a velocity-dependent increased in tonic stretch reflexes with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex, as one components of the upper motorneuron syndrome". Spasticity is one of the common symptoms of stroke patients and frequently interferes with the motor functions such as gait, posture and activities of daily living. Therefore, its management is becoming a major issue in physical therapy. The purpose of this study was to determined the effects of reciprocal inhibition by isometric contraction of pre-tibia muscle on spasticity in hemiplegic patients through Hoffmann reflex. The subjects were consisted 45 patients who had hemiplegia due to stroke. All subjects randomly assigned to 3 group: manual reciprocal inhibition program group(manual group), neuromuscular electrical stimulation group(NMES group) and control group. The manual group received voluntary isometric contraction of pre-tibia muscle. The NMES group received neuromuscular electrical stimulation on tibialis anterior. The control group was not received any therapeutic intervention. Before and after experiments, Hoffmann reflex, M-wave and Modified Ashworth scale was measure in all patients. The data of 30 patients who complete experimental course were statistically analysed. Modified Ashworth scale were significantly decreased after experiment in manual group(p<.01). The Hmax/Mmax ratios were significantly decreased after experiment in manual group(p<.01). There were no statistical difference between pre-test and post-test with modified Ashworth scal in NMES group(p>.01). There were no statistical difference between pre-test and post-test with Hmax/Mmax ratios in NMES group(p>.01). There were no statistical difference between pre-test and post-test with modified Ashworth scale in control group(p>.01). There were no statistical difference between pre-test and post-test with Hmax/Mmax ratios in control group(p>.01). The present results revealed that reciprocal inhibition which produced by voluntary isometric contraction of pre-tibia muscle can be reduce spasticity of gastrocnemius. Therefore, reciprocal inhibition is useful improve functional activities in hemiplegic patient. Further study should be done to analyse the effects of intervention duration of reciprocal inhibition, appropriate muscle contraction, optimal time to apply the reciprocal inhibition in more long period.
