Five elements motion and six kinds of natural factors influence not only human disease but also difference of medicine effect. Because the climate of summer is very hot, that is easy to increase the properties of hot medicines, a doctor must be careful to use it in summer. Also the climate of winter is very cold, that is easy to increase the properties of cold medicines, a doctor must be careful to use it in winter. But in the certain conditions to use diaphoretics or purgatives, in spite of that regulation a doctor can use them.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Recently as construction industry become large-sized and complex, construction type of the saving-energy is recommended. So, practical technology of high-flowabillity concrete to solve placabillity and workability is more attracted. This study is regarding the series of experiment carried out to identity effect on flowing and compressive strength due to super plasticizer and cement weathering. As a result of flow test to identify fluidity of cement, cement fluidity increase as the cement weathering increase. However, the fluidity after 1 hour was not measured in all cases except the cement paste using the polycarbonate. The results of compressive tests of concrete show that early compressive strength is extremely decreased with the cement weathering. Especially, strength loss of the 4th step of cement weathering is more then 65%, compared to the strength of concrete using the fresh cement. Polycarbonate produces higher 1 day compressive strength then others and Naphthalene sulphonate produces higher 38 day compressive strength then others.

Renal cell carcinoma can presents wide range of signs and symptoms, and commonly associated with paraneoplastic syndrome. Paraneoplastic manifestations are present in up to 20% of patients with renal cell carcinoma. There is convincing evidence that renal cell carcinoma tumor cells elaborate proteins that serve as mediators of endocrine (ex ; ectopic production of parathyroid hormone-related protein or erythropoietin) as well as nonendocrine paraneoplastic syndromes. A paraneoplastic syndrome may be the various clinical presentation of renal cell carcinoma in a significant number of patients, therefore mimicked other general disease. We report a case of renal cell carcinoma associated with paraneoplastic syndrome mimicking pyelonephritis.

Most engineering products contain more than one component. Failure occurs either at the connection itself or in the component at the point of attachment of the connection in many engineering structures. The allocation and design of connections such as bolts, spot-welds, adhesive etc. usually play an important role in the structure of multi-components. Topology optimization of connection component provides more practical solution in design of multi-component connection system. In this study, a topology optimization based on density distribution approach has been applied to optimal location of fasteners such as T-shape, L-shape and multi-component connection system. From the results, it was verified that the number of iteration was reduced, and the optimal topology was obtained very similarly comparing with ESO method. Therefore, it can be concluded that the density distribution method is very suitable for topology optimization of multi-component structures.

The test of three point bending and vickers hardness have been carried out to investigate mechanical characteristics of glass-ceramics for artificial dental crowns. In addition, thermal dilation test also carried out to examine bonding properties between dental glass-ceramics and metal base(Ni-Cr alloy). The result of bending test showed the maximum strength of about 80 MPa. Thermal expansion coefficient changed from 9.2 × 10^(-6)/℃ to 17.8 × 10^(-6)/℃ with increasing of leucite content(0-50wt%) in glass matrix. Bonding property is the best case between leucite : glass = 50 : 50 (%) with Ni-Cr alloy.

This paper deals with the design of an adaptive linear-quadratic Gaussian controller to achieve regulation and tracking for non-minimum phase systems represented by a discrete single input-output stochastic state equation including white noise with a Gaussian distribution function. The parallel adaptive structure proposed by Landau has been adopted and an identification algorithm is used to obtain an unbiased estimation of the parameters. Applicability of an adaptive linear-quadratic Gaussian controller and the influence of each of the constants needed in the adaptation algorithm have been investigated. It is shown that the adaptive linear-quadratic Gaussian controller can achieve the fast adaptive control, when the system has the reference signal with a short period and abruptly varing parameters. With respect to white noise, this paper can be considered an extents of adaptive linear-quadratic controller proposed by Samson.
