Objectives : Postpartum depression is a kind of serious problem which influences on the parturients, her family. In this case we tried psychotherapy to postpartum depression patient. Methods : We treated the patient with Oriental psychotherapy. And then we compared postpartum depression before treatment with on after treatment by Korean version of Edinburgh Postnatal Depression Scale(K-EPDS). Results : After treatments, the clinical symptoms were improved and K-EPDS was reduced 16 to 6. Conclusions : Oriental psychotherapy is effective on postpartum depression.

Residents of Qidong, Peoples Republic of China, are at high risk for development of hepatocellular carcinoma, in part due to consumption of foods contaminated with aflatoxins. Chlorophyllin, a mixture of semi-synthetic, water-soluble derivatives of chlorophyll that is used as a food colorant and over-the-counter medicine, has been shown to be an effective inhibitor of aflatoxin hepatocarcinogenesis in animal models.(omitted)

This work presents a novel facial descriptor, which is named as multiscale adaptive local directional texture pattern (MALDTP) and employed for expression recognition. We apply an adaptive threshold value to encode facial image in different scales, and concatenate a series of histograms based on the MALDTP to generate facial descriptor in term of Gabor filters. In addition, some dedicated experiments were conducted to evaluate the performance of the MALDTP method in a person-independent way. The experimental results demonstrate that our proposed method achieves higher recognition rate than local directional texture pattern (LDTP). Moreover, the MALDTP method has lower computational complexity, fewer storage space and higher classification accuracy than local Gabor binary pattern histogram sequence (LGBPHS) method. In a nutshell, the proposed MALDTP method can not only avoid choosing the threshold by experience but also contain much more structural and contrast information of facial image than LDTP.

Crude polysaccharides from rapeseed meal (PRM) were extracted with 0.3% NaOH aqueous solution, followed by further purifications and 2 fractions, namely PRM1 and PRM2, were separated with a DEAE-cellulose DE-52 column. Their primary compositions were analysed and antioxidant activity was determined, including scavenging activity toward superoxide anion radicals, hydroxyl radicals, and nitric oxide radicals, reducing power, and inhibitory effects against the microsomal lipid peroxidation, compared to that of L-ascorbic acid. The results indicated that PRM1 and PRM2 exhibited not only good reducing power and inhibitory effects on the microsomal lipid peroxidation, but also strong scavenging activity toward superoxide anion radicals, nitric oxide radicals, and hydroxyl radicals. In addition, positive correlations were also observed between the superoxide anion radical scavenging activity and the protein contents of the polysaccharides, and the reducing power and the sulfate contents. These findings thus clearly suggest the polysaccharides possess direct and potent antioxidant activity.

The full-bridge inverter, widely used for single-phase photovoltaic grid-connected applications, presents a leakage current issue. Therefore, an AC bypass branch is introduced to overcome this challenge. Nevertheless, existing modulation strategies entail drawbacks that should be addressed. One is the zero-crossing distortion (ZCD) of the AC current caused by neglecting the AC filter inductor voltage. Another is that the system cannot deliver reactive power because the AC bypass branch switches at the power frequency. To address these problems, this work proposes an optimized hybrid modulation strategy. To reduce ZCD, the phase angle of the inverter output voltage reference is shifted, thereby compensating for the neglected leading angle. To generate the reactive power, the interval of the negative power output is calculated using the power factor. In addition, the freewheeling switch is kept on when power is flowing into the grid and commutates at a high frequency when power is fed back to the DC side. In this manner, the dead-time insertion in the high-frequency switching area is minimized. Finally, the performances of the proposed modulation strategy and traditional strategies are compared on a universal prototype inverter. Experimental results validate the theoretical analysis.

Indoor air quality has attracted great attention in recent years and thus the importance of managing finishing materials in terms of pollutant source control is being emphasized. Managing the finishing material at the design stage maximizes the efficiency of IAQ control at the following construction stage. However, there are insufficient investigations on the application of a specific finishing material management process, a database management system or a finishing material management process network. As a result, the main purposes of this study comprise comprehensive evaluation of IAQ performance from the selected finishing materials and auxiliary materials, application of the material management system basing on the types and characteristics of toxic substances generated from the indoor finishing materials, investigation of IAQ evaluation standard, and the overall IAQ evaluation method for the design parts. The result of this study will be the basic data to construct DBMS for management of finishing materials with respect to IAQ.

1. Object of research Dongyi Soose Bowon Sasang Chobongyun and DongmuYugo were written by Lee je-ma befare Dongyi Soose Bowon. He explained in full detail Sasang Constitutional symtoms more than symtoms in Dongyi Soose Bowon. I tried to find his early medical views on Sasang Constitutional disease. 2. Method of research It was researched as contents with his writing surh as Dongyi Soose Bowon Sasang Chobongyun and DongmuYugo. 3. Results and conclusions (1) Dongmu was tried to explain the Sasang Constitutional physiological and pathological symtoms with ordinary symtoms. It is a his own implementation that he made an analysis of Sasang Constitutional symtoms. (2) We can take advantage of the contents clinically which has full of expression that there is a difference between the constitutional symtoms. (3) It is a guide post that can be expected the appearance of disease even if it were not in poor health

While Korean construction companies are adapting themselves to rapidly changing business landscape at home and abroad, intensifying competition among competitors in local as well as global market deteriorates the profitability of construction industry, which leads to another problem. In response to such challenges, many construction companies continue to innovate their business portfolio and organization structure, with strong commitment to business process innovation. Furthermore, they need to analyze the productivity of project site management manpower overhauling business processes systematically and develop effective alternative strategies. This research aims to analyze the productivity of project site management manpower. Current operational practices of construction site organizations have been analyzed with focus on large construction companies in Korea and data gathered from project sites have been analyzed from a wide range of perspectives, In so doing, this research is expected to provide basic inputs for any subsequent attempt to estimate proper resource requirement for site management tasks in construction projects and analyze the management productivity of such resources by enabling construction companies to better understand the current operational status of site organization.

In this study, we structuralized the diagnostic indices used for pattern identification (PI) of stroke, and suggested an AHP method to obtain the weights of PI indices. AHP of the subjects under consistency ratio 0.1 showed that the critical indices for stroke PI consists of 9 for Qi-deficiency, 13 for Phlegm/dampness, 7 for blood stagnation, 12 for Yin-deficiency and 16 for Fire/heat. Furthermore, AHP analysis rendered the weights of indices of each PI that will be useful for oriental medical experts to perform objective PI.
