Objectives: We intended to identify differences of general symptoms related to existence & nonexistence of uterine myoma. Methods: We surveyed 948 women from 35 to 45 years old who had received Korean oriental medical questionnaires about general symptom patterns and abdominal & pelvic ultrasonography at Kyung-Hee University medical center from May 2007 to October 2008. After we divided the women into two (uterine myoma or normal) groups by ultrasonography result, we compared general symptom patterns of the uterine myoma group with those of the normal group. Results: In relation to digestion pattern, appetite showed statistically significant difference between the normal and uterine myoma groups. In relation to evacuation pattern, stool frequency showed statistically significant difference between the normal and uterine myoma groups. In relation to psychologic pattern, difference in oppression in the chest & palpitation showed statistical significance between the groups. In relation to the other patterns, differences in throat discomfort & hypertonicity of nape neck showed statistical significance between the normal and uterine myoma groups (p<0.05). Conclusions: The result showed that prevalence of uterine myoma should be considered in respect to digestion pattern, evacuation pattern, and psychologic pattern. We need further study after increasing the size of the uterine myoma group and improvement of general symptom questionnaires.

The purpose of this study is to improve productivity of architectural space planning(A.S.P,) by computer system and to optimize ASP. A searching algorithm is the best way to slave optimized A.S.P. Because architectural design is too many various site situations and client's demands to specify the general solving methods. This method seek the best design case in all possibility and to be modeled as this; Seongbukgu's case that is city structure former times negative by in facilities utilization of the near street limit. But, case of Gangnamgu and Songpagu is thought that environment and utilization etc. of area life of old people are affinity with quality of life environment of old people when see that is using various area facilities using electric railway and a bus etc. actively. It is looked by the other that individual's special quality uses area facilities according to life partner's existence and nonexistence and family composition and existence and nonexistence of profession and distinction of sex. Show difference of external behavior according to public garden and market and supermarket and welfare facilities etc.'s location in dwelling environment of area and relation about facilities of area has been formed and old people and dwelling environment of area can know that is that do interaction. Environment that access about facilities may have to be easy, and can live that communicating closely with area's inhabitantses may have to consist so that old people may can run various external life.. Notions of the evaluated value is an profit(+) and expense(-) that decide design intention. To adapt real planning, 1. A raster type space cell has logical site informations. 2. To be evaluate various factor. 3. To reflect operator's design mind, they should add an extra weight on evaluated value.

The purpose of this study is to analyze the characteristics of riverbed variation due to the sediment protection weir located on the estuary of the main stream of Taehwa river using I-D finite difference model, HEC-6 model, and the followings are the results of estimating sediment transport rate, amount of scour or deposition, and accumulated amount of deposit according to before and after of the sediment protection weir removal with various flow rates in the channel. Ackers-White transport function produced the greatest sediment transport rate while Meyer-Peter showed the smallest sediment transport rate at the most down stream area of the watershed through the sediment transport rate analyses for various flow rates according to the existence or nonexistence of the sediment protection weir. Toffaleti's and Colby transport function were closest to the average value, and the difference among the results of the sediment transport functions showed up to 8～9 times. Duboy's transport function produced the greatest riverbed variation while Toffaleti's showed the smallest variation through the riverbed variation analyses according to the existence or nonexistence of the sediment protection weir. Yang's was closest to the average value, and the difference among the results of the riverbed variation analyses ranged from 1.4 times to 11 times. It is thought that a sediment transport function must be selected very carefully with respect to the criteria of sediment yield estimation because the analysis results of the sediment transport rate and riverbed variation according to flow rates showed significant differences among the sediment transport functions, and the differences of sediment transport rate and riverbed variation according to the various sediment transport functions decreased as the flow rate increased.

The purpose of this study was to examine factors contributing to financial resources interchange type and amount of the middle aged and the elderly household. For this study, the 6th KLIPS data was used, and sample size was 1,679 households including those with head of household being over the age of 50. Statistical analysis was conducted to examine frequency, percentile, mean and standard deviation, Pearson's correlation, Anova, Duncan's multiple range test and Heckman analysis First, Interchange amount of Benefits type household was significantly different according to the householder's gender, existence or nonexistence of a spouse, age, educational background, home ownership, family type and place of residence. However, interchange amount of provide- type households were significantly different according tohouseholder's gender, existence or nonexistence of a spouse, educational background, whether retired or not, and home ownership. Second, The receptive type of households and net receptive expense of households in terms of the financial resources interchanges and the findings of Heckman analyses suggest that the variables to have a significant effect on the receptive types of financial interchanges were as gender, age, education level, retired or not, and current economics. Factors having an effects on net receptive expense were age, and family type and for the number of receptive of financial resources, whether there is the receptive of financial resources, total income, total asset. Third, The supplying type of households and net supplying expense of households in terms of the financial resources interchanges, whether or not the type of financially supplying households is significant were residential area, total income, house ownership. Factor having an effect net supplying expense were age, family type, whether there is the supplying of financial resources, family satisfaction, and house ownership.

The prevalence of patent foramen ovale (PFO) in healthy persons was estimated as about $10{\sim}25%$ and was up to 40% in patients with stroke. Transesophageal echocardiography (TEE) was considered to be the most sensitive method to detect PFO and was used as the gold standard. Transcranial doppler sonography (TCD) of the middle cerebral artery (MCA) during a contrast (saline bubble) injection has recently been proposed as an alternative detecting method for PFO. In this study, we would like to know the difference between TCD value and TEE value in subjects with cryptogenic ischemic stroke. We performed TCD and TEE tests to detect PFO on 64 patients (30 women and 34 men, mean age was 59.4 years) with cryptogenic ischemic stroke. PFO prevalence through TCD was 45.3% (29 of 64 patients) and the prevalence through TEE was 34.4% (22 of 64 patients). There was no statistical significance between PFO test and TCD test (P=0.206). But TCD had a sensitivity of 90.9% (20 of 22 patients), specificity of 78.6% (33 of 42 patients), positive predictive value of 69.0% (20 of 29 patients), and negative predictive value of 94.3% (33 of 35 patients). We concluded that TCD was a highly sensitive method for detecting a right-left shunt. Therefore, the non-invasive TCD test is a method more effective than the anti-invasive TEE test in the cost and evaluation of the existence or nonexistence of right to left shunt in addition to the screening method of the cerebrovascular disorder. Considering these points, TCD test could be recommended for patients with cryptogenic ischemic stroke as a useful and convenient method for screening of the existence or nonexistence of a right to left shunt caused by PFO.

This paper represents a comparison the difference between existence and nonexistence of soundproof trees for road traffic noise. Also we suggested that the simple equation has been derived using a single regression analysis for predicting levels of $Leq_{th}$ at a given distance from a road in terms of the flow rate, the mean speed of the traffic, and the percentage of the type vehicles in the existence and nonexistence of soundproof trees. We classified a vehicle into four and analyzed contribution rate to traffic volume. As a result, the order showed as followed: light vehicle>medium vehicle>heavy vehicle>motorcycle. However, the results of analyzing contribution rate with between traffic volume and traffic noise by the each type showed as followed; Motorcycle>Light vehicle>Medium vehicle>Heavy vehicle. This study showed that the most a lof of traffic volumes of the three vehicles(light vehicle, medium vehicle and motorcycle) and heavy vehicle were existed in 67 km/h and 61 km/h of car speed, respectively. The total traffic noise to the mean car speed decreased because of the inflow a lot of traffic volumes between 2016 and 2388 in the range of 67 km/h of light vehicle speed, in traffic composition of 4.75% heavy vehicles, and 1.11% motorcycle. the final result for this study showed that statistical paired t-test for between existence and nonexistence of soundproof trees was significant(p<0.05) and the difference between daytime and night in the location of the nonexistence of plant communities with the independent sample T-test was significant(p<0.05). However, the independent sample T-test for analyzing the variance of traffic noise between daytime and night was not significant(p>0.05).

The purpose of this study is to find inelastic behavior and ductility capacity of reinforced concrete bridge columns under earthquake. Material nonlinearity is taken into account by comprising tensile, compressive and shear models of cracked concrete and a model of reinforcing steel. The smeared crack approach is incorporated. In boundary plane at which each member with different thickness is connected, due to the abrupt change in their stiffness local discontinuous deformation can be taken into account by introducing interface element. Also an analytical model is developed to express the confining effects of lateral tie which depend on the existence or nonexistence and the amounts of transverse confinement, etc. The proposed numerical method for inelastic behavior and ductility capacity of reinforced concrete bridge columns will be verified by comparison with reliable experimental results.
