In this paper, we study the boundedness of the commutator H^b_Ω formed by the rough Hardy operator H_Ω and a locally integrable function b from homogeneous Herz spaces to homogeneous weak Herz spaces. In addition, the weak boundedness of H^b_Ω on central Morrey spaces is also established.

Purpose: The purpose of this study is to classify space types according to the operating system of health examination centers and compare and analyze their sizes. Methods: Seven examination centers under the K Medical Research Institute with the same operating system and similar examination types and functional spaces are the subject of the investigation. Research is conducted through field investigation, user surveys, and drawing analysis. Results: The operating method of the health examination center can be largely divided into the function dispersed type and the function central type. The function dispersed type was planned as a vertical type, and the function central type was planned as a horizontal type. In the case of the function dispersed type, since the examinees move vertically to use the endoscope center and special examination center, the efficiency of the vertical movement must be considered when planning the function dispersed type of facility. The function dispersed type plans to increase work and manpower efficiency by arranging the areas used at the start and end of the examination. Because the function central type horizontally arranges related functions by area, it should be planned in a structure that makes it easy for examinees to find their way. Implications: Through this study, it is judged that it is possible to suggest architectural planning considerations that vary depending on the operation system of the examination center.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time($1905{\sim}1919$), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

We show the cumulants of a minimal sufficient statistics in k parameter natural exponential family by parameter function and partial parameter function. We nd the cumulants have some merits of central moments and general cumulants both. The first three cumulants are the central moments themselves and the fourth cumulant has the form related with kurtosis.

5-Hydroxytryptamine(5-HT)를 가토뇌실내로 투여 (icv)하면 이뇨와 Na배설증가가 초래되며, 이러한 작용은 $5-HT_1$ 수용체길항제인 methysergide에 의하여 차단되므로 중추성 신장기능조절에 있어 중추 tryptamine계의 관련이 시사된 바 있다. 본 연구에서는 $5-HT_2$ 길항제로 알려진 ketanserin (KET)를 이용하여 $5-HT_2$ 수용체의 역할을 구명하고자 하였다. KET $120\;{\mu}g(=0.3{\mu}moles)/kg$ icv는 신혈류역학에는 아무런 변동을 일으키지않으나 유의한 Na배설증가를 초래하여, 세뇨관에서의 Na 재흡수 감소가 시사되었다. 전신혈압은 약간 감소하였다. 정맥내 투여시에는 유의한 기능변동을 볼 수 없었다. 5-HT $200{\mu}g/kg$ icv는 경미하나 유의한 Na배설증가 및 이뇨작용을 나타냈다. 그러나 신장기능에 그다지 큰 영향을 미치지 않는 양인 $40{\mu}g/kg$의 KET icv후에는 5-HT의 작용이 크게 강화되어, Na배설분획이 9.3%에 달하였다. Norepinephrine, dopamine, histamine과 같은 다른 생체아민의 신장작용은 KET전처치에 의하여 영향받지 아니하였다. 본 연구는 중추 $5-HT_1$ 수용체와는 반대로 중추 $5-HT_2$ 수용체는 항이뇨 및 Na배설감소를 매개하고 있으며, 중추 tryptamine계는 신장기능을 이중적으로 조절하고 있음을 시사하였다.

The simultaneous suppression of sidelobes and the sharpening of the central peak in the process of diffraction pattern detection based on asymmetric apodization have been investigated. Asymmetric apodization is applied to a semicircular array of two-dimensional (2D) aperture functions, which is a series of 'coded-phase arrays of semicircular rings randomly distributed over the central circular region of a pupil function' and is similar to that used in the field of diffractive optics. The point spread function (PSF) of an imaging system with asymmetric apodization of the discrete type has been found to possess a good side with suppressed sidelobes, whereas its bad side contains enhanced sidelobes. Further, the diffracted field characteristics are obtained in the presence of these aperture functions. Asymmetric apodization is helpful in improving the performance of the optical gratings or 2D arrays used in real-time imaging techniques.

Presently, rapidly changing and unstable global economic environments demand engineers. Products should be designed to increase profits by lowering costs and provide distinguished performance compared with competitors. This study aims to optimize the design of the power-transmission drive shaft. The mass is reduced as an objective function, and the stress is constrained under a constant value. To reduce the number of experiments, CCD (central composite design) and D-Optimal are used for the experimental design. RSM (response surface methodology) is employed to construct a regression model for the objective functions and constraint function. In this problem, there is only one objective function for the mass. The other objective function gives 1; thus, NSGA-II is used.

This paper describes novel methods to construct fuzzy inference rules with gradient descent. The present methods have a constructive mechanism of the rule unit that is applicable in two parameters: the central value and the width of the membership function in the antecedent part. The first approach is to create the rule unit at the nearest position from the input space, for the central value of the membership function in the antecedent part. The second is to create the rule unit which has the minimum width, for the width of the membership function in the antecedent part. Experimental results are presented in order to show that the proposed methods are effective in difference on the inference error and the number of learning iterations.
