The aim of this thesis is to examine the effect of the diuretics in the Sasang constitutional medicine those are not categorized to the diuretic in the established herbal medicine by the way of measuring the change of body edema and the quantity of body moisture through the inbody test, along with the urine volume taken for 24 hours 1. We medicated the diuretic suggested by the DongyiSuseBowon東醫壽世保元 into the tested group and measured the change of the urine volume, the quantity of body moisture and the degree of body edema. The results are the followings below. 1) Soeumin The change in the urine volume and body moisture showed no responsibility, but the degree of body edema decreased with the responsibility. 2) Soyangin All of the degree of body edema and the urine volume, and body moisture showed decrease. 3) Taeumin The urine volume and body moisture increased but showed no responsibility. Also the degree of body edema decreased within the normal limit which can not be accepted. 4) The medicine of the Sasang Constitutional Medicine can not be simply thought to be the diuretic, but it has the function that excretes the moisture which functions negatively in the body and causes edema, as well as the function of the adjustment of metabolism that preserves the normal amount of moisture. This is the good example which is the concept of the adjustment therapy suggested by The Sasang Constitutional Medicine 2. Through the results above, we can find that the diuretic suggested by The Sasang Constitutional Medicine functions in the way that is differently explained by the herbal medicine.

Objectives : The purpose of this study is to perform quantity and quality assessment of randomized controlled trials(RCTs) in the journal of oriental rehabilitation medicine(JORM). Methods : Upon extracting randomized controlled trial from all the articles published in the JORM from 1991 to 2009, assessments were made on the adequacy of the consolidated standards of reporting trials(CONSORT) checklist. The assessment were performed independently by two researchers, and adjustment of the differences were done by discussions. Results : Among the 824 articles from 1981 to 1999, 33 RCTs were selected. 4 RCTs were published from 1991 to 2002, and 29 RCTs were published from 2003 to 2009. Adequacy of the CONSORT checklist was 29.4%(27.3% from 1999 to 2005, 31.6% from 2006 to 2009). Conclusions : RCTs of the JORM consistently increased in quantity and quality. But researchers should make an effort to reporting more accurate.

This study investigate the impact of supply chain contracts on supply chain performance. This study employed Price adjustment contract(PAC) and Quantity adjustment contract(QAC) as two main types of a vertical coordination mechanism. We simulate different types of coordination mechanisms with various degrees of demand uncertainties and several capacity tightness scenarios. This study shows that PAC and QAC significantly enhance the supply chain profits and fill rates suggesting that supply chain performance can be improved by implementing a proper coordination mechanism depends on the level of a capacity tightness and demand uncertainty.

It has been repeatedly reported that the quality and quantity of relationships with other people moderate responses to stress and influence health and adjustment. This evidence has stimulated research on the characteristics of social support. In this review, the definition of social support for parents will be discussed. This study also will connect the concept of social support with family theories such as the human ecology theory and the developmental contextualism. The findings from previous studies will be summarized to examine the effects of social support on parenting and to understand the social support within a cultural context.

Machines and facilities are physically or chemically degenerated by continuous usage. One of the results of this degeneration is the process mean shift. The representative type of the degeneration is wear of tool or machine. According to the increasing wear level, non-conforming products cost and quality loss cost are increasing simultaneously. Therefore a periodic preventive resetting the process is necessary. The total cost consists of three items: adjustment cost (or replacement cost), non-conforming cost due to product out of upper or lower limit specification, and quality loss cost due to difference from the process target value and the product characteristic value among the conforming products. In this case, the problem of determining the adjustment period or wear limit that minimizes the total cost is called the 'process mean shift' problem. It is assumed that both specifications are set and the wear level can be observed directly. In this study, we propose a new model integrating the quality loss cost, process variance, and production volume, which has been conducted in different fields in previous studies. In particular, for the change in production volume according to the increasing in wear level, we propose a generalized production quantity function g(w). This function can be applied to most processes and we fitted the g(w) to the model. The objective equation of this model is the total cost per unit wear, and the determining variables are the wear limit and initial process setting position that minimize the objective equation.

Tail-grouting is an effective measure in shield engineering for filling the gap at the shield tail to reduce ground deformation. However, the gap-filling ratio affects the value of the gap parameters, leading to different surface settlements. It is impossible to adjust the fill ratio indiscriminately to study its effect, because the allowable adjustment range of the grouting quantity is limited to ensure construction site safety. In this study, taking the shield tunnel section between Chaoyanggang Station and Shilihe Station of Beijing Metro Line 17 as an example, the correlation between the tail-grouting parameter and the surface settlement is investigated and the optimal grouting quantity is evaluated. This site is suitable for conducting field tests to reduce the tail-grouting quantity of shield tunneling over a large range. In addition, the shield tunneling under different grouting parameters was simulated. Furthermore, we analyzed the evolution law of the surface settlement under different grouting parameters and obtained the difference in the settlement parameters for each construction stage. The results obtained indicate that the characteristics of the grout affect the development of the surface settlement. Therefore, reducing the setting time or increasing the initial strength of the grout could effectively suppress the development of surface subsidence. As the fill ratio decreases, the loose zone of the soil above the tunnel expands, and the soil deformation is easily transmitted to the surface. Meanwhile, owing to insufficient grout support, the lateral pressure on the tunnel segments is significantly reduced, and the segment moves considerably after being removed from the shield tail.

The purpose of this paper is to model price formation and analyze demand structures for fishes under the restriction of Korean fisheries regulations. This study suggests the model that the price of fish is formed by its quantity, expenditure, and habit persistence. In economic literature, such a fishery market demand is called the inverse demand with dynamic habit persistence. Based upon a static differential price formation model, the paper has generalized it dynamically incorporating habit persistence effects. The empirical results show that all the species have values less than one and (-) sign of price flexibilities, thus being price inflexible. The estimated habit adjustment coefficients are significant at the level of 1%. Especially, TAC species have the smaller values of them than those of other main fish species. The contribution and results are summarized as follows. First, the fishery market demand has a strong dynamic effects from habit persistence. Second, the fishery market demand structure could be analyzed in a way different from the ordinary demand analysis, which is based upon price flexibility, scale flexibility, and cross adjustment flexibility. Third, the limitation of this paper is that it ignores the increasing stock effects by catching restrictions, thus raising consumers' benefit in the future.
