The study was performed to determine the reliability and validity of the 'Qi Blood Yin Yang Deficiency Questionnaire (Qi Blood Yin Yang DQ)' for the 100 subjects with chronic fatigue. After 100 subjects respond to the 'Qi Blood Yin Yang DQ', Korean medical doctor classified the subjects into 4 groups such as Qi deficiency group, Blood deficiency group, Yin deficiency group and Yang deficiency group. 100 subjects were retested in the same way after 3 weeks. The reliability and the validity of the questionnaire were inspected. Internal consistency of the 'Qi Blood Yin Yang DQ' was excellent (Cronbach alpha 0.916). Test-retest reliability was good (intra-class correlation coefficient 0.699). Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The 'Qi Blood Yin Yang DQ' consisted of 4 factors. The factor 1, 2, 3 and 4 showed 'Qi deficiency', 'Yin deficiency', 'Yang deficiency' and 'Blood deficiency' respectively. The 'Qi Blood Yin Yang DQ' restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.

The purpose of this study was to observe the effects of the polysaccharide(G009) obtained from liquid cultured Ganoderma lucidum IY009 on the lipidperoxidation in rat liver microsome. It is well known that the polysaccharide of G. lucidum have the hepatoprotective activity, antitumor activity etc., which was thought to have the relationship to anti-lipidperoxidation. In order to the estimate the effects of anti-lipidperoxidation of the polysaccharide obtained from G. lucidum IY009, enzymatic and nonenzymatic reaction were performed, in vitro, in rat liver microsome. In enzymatic lipid peroxidation reaction by ADP/FeCl$_3$/NADPH and $CCl_4$/NADPH, G009(1mg/ml) inhibited 77.4%, 39.4%, respectively, and the nonenzymatic reaction strongly exhibited 97.4% inhibition. And also, in enzymatic and nonenzymatic inducers treated with G009, the formation of MDA was progressively greater decreased by raising G009 concentration. These results suggest that anti-lipidperoxidation by G009 treatment may be play an important part in liver protection action.

When we see normal gait, gait cycle is seperated as stance phase and swing phase. It needs 6 determinant of gait of pelvic rotation, pelvic tilt, knee joint of stance phase, ankle and foot motion, ankle and knee motion, and pelvic movement to be accomplished. In addition, a joint and muscle action is accomplished biomechanically at the same time with its gait cycle. In oriental medicine, the relationships between chang-fu physiology and meridian physiology are summaried as follows ; ${\bullet}$ chang-fu physiology : Spleen manages the extremities. Liver manages soft tissues. Liver stores blood. Kidney stores essences. Kidney manages bones. ${\bullet}$ meridian physiology : The Leg Greater Yang Meridian and meridian soft tissues The Leg Yang-Myeong Meridian and meridian soft tissues The Leg Lesser Yang Meridian and meridian soft tissues The Leg Greater Yin Meridian and meridian soft tissues The Leg Lesser Yin Meridian and meridian soft tissues The Leg Absolute Yin Meridian and meridian soft tissues Especially, we can find out relations between in a "blood supplied feet can walk well" that explains "blood regulations and by liver nourishing effects"that is the closest concept of muscle. Abnormal gaits are due to three causes as following; first, physical defect secoud, pain third, nervous system or instability of muscle. In oriental medicine, we can know relationship in "atrophy, numbness, stroke, convulsion, muscular dystrophy of knee, rheumatoid arthritis, five causes of infantile growing defects, five causes of softening, sprain". Especially, atrophy is the most important symptom. Gait evaluation should be emphasized where a point can walk 8 feet to 10 feet considering stride width, stride length, the body weight center, stride number, flexion, extension, rotation of a joint as a standard factor. The point is we should find out something strange in a patient's side, front and back view. After that we should find out its cause as an index that we can observe abnormal findings in a joint and muscle.

Optical profile and spectral absorption of suspended solids in waters of Sanya bay was measured on August 8-14, 2003. Optical profile was taken by using MicroPro optical profile. Apparent optical indexes, vertical diffuse attenuation coefficient ($K_d$) and water leaving radiance (Lw), were calculated. $K_d$ at the blue end of the spectrum was greater than that at the red end of the spectrum in waters near Sanya River mouth, however, in waters near open sea, $K_d$ at the blue end of the spectrum was smaller than that at the red end of the spectrum. Distribution of water leaving radiance was relatively higher in waters near Sanya River mouth, but relatively weaker in near open sea water. Spectral absorption of suspended particulates was also measured. Results showed that the spectral absorption of chlorophyll a was greater in waters near Sanya river mouth, but relatively weaker in waters near open sea, which indicated higher concentration of phytoplankton in waters near Sanya river mouth. Except for water at the 5th sampling station, the ratio of spectral absorption of chlorophyll a to total suspended particulates in surface waters was greater than that in bottom waters at all stations.

The objective of this study was to examine the effect of compensatory growth nutritional regimen on mammary gland growth and lactation. One hundred twenty-two Sprague Dawley female rats (35 days of age) were randomly assigned to either a control or a stair-step compensatory nutrition (SSCN) feeding regimen or an alternating 2-2-3-3-week schedule beginning with 40% energy restriction for 2 weeks followed by re-alimentation (control diet) for 2 weeks. Pup weight gain and milk yield were improved 8% and 8 to 15%, respectively, by the SSCN regimen. The gene expression of $\beta$-casein was 2.3-fold greater in the SSCN group than in the control group during early lactation, but they were greater at all stages of the second lactation. The gene expression of insulin-like growth factor-I was 40% lower in the SSCN group than in the control group during early lactation of the second lactation, but during late lactation it was 80% greater than in the control group. The concentration of serum corticosterone tended to be higher in the SSCN group during the late stage of the first lactation. These results suggest that the stair-step compensatory nutrition regimen improves lactation performance and persistency by modulation of cell differentiation and apoptotic cell death.

The purpose of this study was to investigate the effect of martial art type and target height on the ground reaction force factors during Dollyuchagi motion. Data were collected using force plate. Five Taekwondo players and five Hapkido players were tested during Dollyuchagi motion to three different target heights(0.8, 1.2, 1.6 m). After analysis of kinetics using force plate data, maximum vertical ground reaction force was 1.62~2.44 BW, and impulse was $0.66\sim1.01 BW{\cdot}s$. Even though there was no difference for maximum ground reaction forces and impulse between Hapkido and Taekwondo, as target height was higher, impulse increased. Anterior-posterior and vertical ground reaction forces at kicking foot take-off were greater with target height, although there was no difference for medio-lateral force with target height. At impact there was significant difference for anterior-posterior ground reaction force between Hapkido and Taekwondo players. Taekwondo players' force (range, -0.23~-0.26 BW) was greater than Hapkido players's force (range, -0.08~-0.14 BW).

The electrical activities of masseter muscle were recorded on 9 subjects with unilateral fracture of mandible. The electromyographic studies were executed with 2 channel RS dynograph recorder for electromyography. The graphs were recorded in the physiologic rest position, incisal occlusion, molar occlusion, left lateral excursion, right lateral excursion, and protraction. The following conclusions were drawn; 1. In the physiologic rest position, incisal occlusion, molar occlusion, and protraction, the electrical potentials of the masseter muscle were greater in the affected side. 2. In the right lateral excursion, the electrical potentials of the masseter muscle were greater in the right side, and in the left lateral excursion, greather in the left side. There is no correlation mutually between the affected side and unaffected side.

In order to study the frost heaving characteristics of soil stabilitized with a quick lime, a cement and a briquette ash, frost heaving tests were performed with 2 kinds of soil sampled at Chonbuk-Do area. Frost heaving of no-stabilizing soil compacted with water content greater than optimum water content was increased as the frost period was increased but in case of samples with water content smaller than optimum water content, the frost period gave no affect about increase and decrease of the frost heaving. Both frost heaving of stabilizing and no-stabilizing soil with water content greater than optimum water content was decreased with the increase of the repetition number of freezing and thawing. There was no increase or decrease of frost heaving in the frost heaving test after 5 times of freezing and thawing.
