In order to correlate the number of eggs In female Enterobius vermicularis with their body length and to re-evaluate the number of eggs liberated by gravid females, a total of 203 worms were examined. Those females were removed from naturally infected orphans with mebendazole (100mg) and had been fixed in 10% formalin(Cho et al., 1981). The decent ones which were selected under dissecting microscope were unbroken, neatly fixed females without contaminated eggs on their surface. The worms were measured by their body length, softened in 0.1N NaOH solution overnight, and teased by dissecting needles. And their number of shelled eggs was measured in a counting chamber made as described by Denham et at. (1971). The results were summarized as follows: 1. The observed females, 4.10~9.90mm long, began to have shelled eggs in uterus when body length was 5.50mm or longer. 2. The percentage of females with eggs in uterus was as follows by range of body length: 25% in 5.50~5.99mm long, 53.3% in 6.00~6.49mm long, 86.7% in 6.50~6.99mm long, 95.2% in 7.00~7.49mm long and 100% in 7.50mm or longer. 3. The mean and standard deviation of egg number were as follows by the length of females: $19{\pm}50$ in 5.50~5.99mm long, $734{\pm}1,597$ in 6.00~6.49mm long, $1,473{pm}1,606$ in 6.50~6.99mm long, $1,530{\pm}2,055$ in 7.00~7.49mm long, $2,567{\pm}2,046$ in 7.50~7.99mm long, $5,598{\pm}2,470$ in 8.00~8.49mm long, $9,318{\pm}2,651$ in 8.50~8.99mm long, $10,678{\pm}2,892$ in 9.00~9.49mm long and $13,323{\pm}1,778$ in 9.50~9.90mm long. 4. The numbers of uterine eggs showed greater individual variation when the female lengths were in range of 5.5~8.0mm. When the female length was longer than 9.0mm, the egg numbers were over 10,000 in majority, and showed lesser individual variations. Above results su99ested that the e99 Production in female 5. vermicularis began in 28~32 days after infection and that in early stapes, the egg Production varied by individual worms, but in gravid females longer than 9. Qmm at last deposited 10,000 to 16,000 eggs in their uterus with the least individual variations.

This paper proposed the sizing system for womens lower clothes. The sizing system was classified according to 4 body types and 5 age groups. The size intervals of waist girth, hip girth, stature, and slacks length were 3cm, 4cm, 8cm, and 5cm respectively. Frequency distribution analyzed with waist girth, hip girth, and stature showed that the most frequent sizes were 86-100-158 in the fattest-medium length H type, 77-92-158 in the fat-short M type, 68-92-158 in the balanced-long A type, and 65-88-158 in the balanced-medium length A type. The number of the sizes for lower clothes, which had frequencies more than 4∼5%, was 33 and each size was presented with slacks length, skirt length, thigh girth, and knee girth. Also frequency distribution analyzed with waist girth, hip girth, and slacks length showed that the most frequent sizes were 86-100-90 in the fattest-medium length H type, 74-96-90 in the fat-short M type, 68-92-90 in the balanced-long A type, and 65-88-90 in the balanced-medium length A type. The sizing system classified by age group had 21 cases in the early twenties, 21 cases in the late twenties, 18 cases in the early thirties, 16 cases in the late thirties, and 8 cases in the forties. This result will contribute to clothing fitness and efficient production.

Background: We investigated association between introduction of the diagnosis-related groups (DRG) system for anal operation and length of stay. Also, we investigated how it is different among hospitals with longer length of stay and among hospitals with shorter length of stay before introduction of the DRG system. Methods: We used data from Health Insurance Review and Assessment which were national health insurance claim data. Total 13,111 cases of anal surgery cases were included which were claimed by hospitals since July 2012 to June 2014. Two-level multivariable regression was conducted to analysis the association between length of stay and characteristics of hospital and patient. Results: Before introducing DRGs, the average length of stay was 5.41 days. After introducing DRGs, average length of stay was decreased to 3.92 days. After introducing DRGs, length of stay has decreased (${\beta}=-1.0450$, p<0.0001) and it was statistically significant. Among hospitals which had short length of stay (shorter than mean of length of stay) before introducing DRGs, effect of introducing DRGs was smaller (${\beta}=-0.4282$, p<0.0001). On contrary, among hospitals which had long length of stay (longer than mean of length of stay) before introducing DRGs, effect of introducing DRGs was bigger (${\beta}=-1.8280$, p<0.0001). Conclusion: Introducing DRGs was more effective to hospitals which had long length of stay before introducing DRGs.

Carbon fiber-reinforced composite materials have been widely used in various industrial fields, but there are limits to increasing their strength and stiffness, because of the short-length fibers that are impregnated in them. In this study, a lab-scale small extruder system was developed with the capability to perform the carbon fiber impregnation and extrusion process in order to evaluate the properties of long-length carbon fiber reinforced thermoplastic composite materials molded by the LFT-D method. Specimens were made with the small extruder to press-mold long-length carbon fiber composite materials and evaluate their material properties. As a result, it was found that the carbon fiber length, press load and carbon fiber contents have a considerable influence on the strength and stiffness. Additional studies on such factors as the mixing screw design and coating of the carbon fiber are needed in order to improve the mechanical properties of carbon fiber composite materials.

PURPOSES : This study is to suggest tunnel length to spray curing compound, based on the field tests. METHODS : At first field test, length from the entrance of tunnel to wet wall was checked by visual survey. The second and third test, various sensors were installed in concrete or in tunnel, such as RH sensor, temperature sensor, portable weather station and etc.. And also, test for bleeding and retaining water of concrete were conducted to evaluate environmental effect on concrete pavement. RESULTS : The result of the field experiment for tunnel length to spray curing compound indicates that length changes depending on tunnel length, season, and location. Environmental condition of a short tunnel was not much different between location near entrance and at center of tunnel. However, in case of a medium and long tunnel, effect of outside environmental condition decreased, when location moved into tunnel center of it. CONCLUSIONS : From the testing results, it can be proposed that optimum tunnel length to spray curing compound is 60m for a medium and long tunnel, and whole length for a short tunnel.

To enhance the proliferation efficiency of Menyanthes trifoliata L. endangered species in Korea, various rhizome cuttings were tested based on cutting length and node numbers. Growth length and increased volume of rhizomes were highest on long cuttings of 10-18cm length. But relative growth length of rhizomes were higher in short cuttings of 2-4cm and medium cutting of 4-10cm length than in long cuttings. Relative increased volume of rhizomes was highest in medium cuttings. The node numbers were not contributed to the efficiency of relative growth of rhizomes. This study suggests that medium length cutting is the best practice for the proliferation of M. trifoliata.

This paper proposed the design bending moments of cantilever slabs with KL-510 load according to span length of long span decks. Their span length range is from 6.0 to 12.0 meter, and length of cantilever slabs is from 30 to 50 percent of their span length. The effects of orthotropic concrete decks, stiffness of steel girders and multiple lane loading factors (MLLF) were reflected in the design bending moments. The proposed design bending moments of cantilever slabs were compared to the design bending moments with DB-24 load.

Purpose: Leg length discrepancy causes the posture deformation, gait asymmetry, and lower back pain. The purpose of this study is to investigate the correlation among functional leg length discrepancy (FLLD), muscle activity, muscle contraction onset time and vertical ground reaction force (vGRF) during simple lifting task. Methods: Thirty-nine subjects participated in this study. FLLD was measured from the umbilicus to medial malleolus of left and right leg using a tape. The subjects performed to lift a 10 kg box from the floor to chest. The muscle activity and muscle contraction onset time of rectus abdominis, erector spinae and rectus femoris was measured using EMG system and vGRF was measured by two force plate. Pearson correlation was used to fine out the correlation among FDDL, muscle activity, muscle contraction onset time and vGRF during simple lifting task. Results: Correlation between FLLD and difference of muscle activity of short-long side was very high (r>0.9) during simple lifting task. Correlation between FLLD and difference of muscle contraction onset time of short-long side was very high (r>0.9) during simple lifting task. And correlation between FLLD and difference of vGRF of short-long side was high (r>0.7) during simple lifting task. Conclusion: This study suggests that there is high correlation between FLLD and muscle activity, muscle contraction onset time, and ground reaction force during simple lifting task. Therefore, FLLD could negatively affect the postural balance.

To clarify the relationship between the medical supply(medical persons and goods) and the use of bed, the author has made comparison among OECD 24 countries. Per Capita Bed-days can be divided into Average Length of Stay and Admission Rate, and these three variables were regressed upon both In-patient Care Beds of all medical institutions including acute somatic, psychiatric, special, nursing homes and other long-term care and Share of Total Health Employment in Total Employment. The result of regression analysis shows a statistically significant positive relationship between In-patient Care Beds and Average Length of Stay, and negative relationship between Share of Total Health Employment and Admission Rate. In addition to Ordinary Least Square(OLS) estimation, amended Bounded Influence Estimation(BIE) was also made to adjust the influence of outliers. Japan shows a very large number of In-patient Care Beds and a very low Share of Total Health Employment, and this medical situation is judged to have close relation to her long Average Length of Stay and low Admission Rate.
