Seowon(書院) is a representing institution in Choseon Dynasty not only educationally but also politically and economically. Due to the artificial crackdown by Daewon-gun in 1871 and destruction by wars, it is difficult to restore and interpret the Seowon accurately at present. It is well known that the 'Basic Form' of the Seowon consists of an inner court, enclosed by the rear gangdang (lecture hall), dongseo-jae (east and west dormitory), and the front munlu (gate pavilion or upper story bower for relaxation), represented by so called 'front-dormitory rear-lecture-hall type', that is, 'jeonjae hudang(前齋後堂) type'. However, it is overlooked that this Basic Form is a product of Youngnam School located only in Youngnam area. A different form, of 'front-lecture-hall rear-dormitory type', or 'jeonndang hujae(前堂後齋) type' is located only in Gyeonggi, Hoseo and Honam area. It has been wrongly analyzed that the type is a result of the later period, emphasizing the memorial service rather than the lecture itself, and worshipping loyalists than Confucian scholars. Analysis encompassing each Seowon architecture has been mistakenly made by historians as "deterioration" of the original educational purpose of the Seowon from the early period to the later period. This paper raises the fact that the form of jeondang hujae type has been established since the early period of Seowon in the 16th Century. It has a unique order of space itself. Here, the lecture hall faces toward sadang (shrine). The inner court, enclosed by east and west jae and the lecture hall, becomes the outer yard of the shrine, and as a result two main spaces of the shrine and lecture area is merged into one. While the munlu of the basic type encloses the inner court of the main area, the munlu of jeondang hujae type is located at the vicinity area. This paper reinterprets the jeondang hujae type not as a form coming out of degenerated period but as a type that belongs to a different Confucian school, the area of Kiho, and concludes that the Seowon is a product of political struggles between the two schools and of the local economical situation. Each school has maintained his own type of form, therefore the remaining Kiho Seowon architecture can be reevaluated.

The purpose of this research is to lay the foundation that middle aged woman takes care of more healthy, beautiful, attractive external features and prepares successful ageing on studying a difference of recognition between an actual somatotype and an ideal somatotype after we examine an actual somatotype and an ideal somatotype in the object of about $40{\sim}50$ middle-aged woman, dwells in Seoul, is the main group of a home consumption socially. The result of comparing a difference between an actual somatotype and an ideal somatotype was showing that in case of a facial form, the group which their faces are an egg-shaped prefers an egg-shaped and the group which their faces are a round-shaped prefers a round-shaped. In case of a silhouette, all groups prefers a normal type most. In case of a shoulder's type, all groups prefer a normal type most. In case of a shoulder-waist line, all groups prefers a Y line most. In case of a breast's form, all groups prefer a normal type most. In case of a back's form, all groups prefer a normal type most. In case of a buttocks' form, all groups prefers a normal type most. In case of a leg's form, all groups prefers a normal type most. On putting together research result as yet, middle aged women wish a similar somatotype irrespective of an age, an obesity measurement and this means a recognition of making an effort to be beautiful is alike. Therefore, it is necessary to recognize a somatotype of middle aged women uprightly and it must be accomplished a continuous, systematic consultation and education about a weight-control on exercising and not to mention of making a desirable eating habit.

The purpose of this study is to find the influence of Chinese falling-rising tone on the pitch pattern of corresponding partly-different-form-same-meaning Sino-Korean words delivered by Chinese learners of Korean and to examine how the falling-rising tone of corresponding Chinese words affects the pitch patterns of Sino-Korean words. The scope of this research is limited to Chinese learners of Korean, especially on two groups of Sino-Korean words - AB:CB type and AB:AC type that the are second-most frequently occuring different-form-same-meaning Sino-Korean words. In this study, Chinese learners pronounced both Chinese words and corresponding Sino-Korean words. Learners' pitch patterns were recorded and analyzed using software and compared with the tone of corresponding Chinese words. Experimental results showed that AB:CB type Sino-Korean words were not affected by Chinese 'falling-rising tone - high and level tone'. As well as AB:CB type, experimental results showed there were no significant influence on the pitch pattern of AB:AC type Sino-Korean words by Chinese falling-rising tone. But it was clear that Chinese learners' made pitch errors on both AB:CB type and AB:AC type Sino-Korean words. In conclusion, the Chinese learners' pitch patterns of partly-different-form-same-meaning Sino-Korean words are different from Korean native speakers', but their pitch errors cannot be attributed to Chinese falling-rising tone.

In this work, a new 3-PSP type spatial 3-degree-of-freedom parallel mechanism is proposed. And a 6 DOF hybrid manipulator which consists of a 3-PPR type planar 3 DOF parallel mechanism and a new 3-PSP type spatial 3-degree-of-freedom parallel mechanism is proposed. Both 3 DOF mechanism modules have closed-form forward position solutions and particularly, 3-PSP spatial module has unique forward position solution. Firstly, the closed-form position analysis and first-order kinematic analysis for the proposed 3-PSP type module are carried out, and the first-order kinematic characteristics are examined via maximum singular value and the isotropic index of the mechanism. It is shown through these analyses that the mechanism has excellent isotrpic property throughout the workspace. Secondly, position and kinematic analysis of the 3-PPR planar module are briefly described. Thirdly, the forward position analysis for the 3-PPR 3-PSP type 6 degree-of-freedom hybrid mechanism consisting of a 3-PPR planar module and a 3-PSP spatial module is performed along with the analysis of the workspace size and first-order kinematic characteristics. The kinematic characteristics of the proposed hybrid manipulator are compared to those of geometrically similar Stewart manipulator.

In this paper, a new form of poly-Genocchi polynomials is defined by means of polylogarithm, namely, the Apostol-type poly-Genocchi polynomials of higher order with parameters a, b and c. Several properties of these polynomials are established including some recurrence relations and explicit formulas, which are used to express these higher order Apostol-type poly-Genocchi polynomials in terms of Stirling numbers of the second kind, Apostol-type Bernoulli and Frobenius polynomials of higher order. Moreover, certain differential identity is obtained that leads this new form of poly-Genocchi polynomials to be classified as Appell polynomials and, consequently, draw more properties using some theorems on Appell polynomials. Furthermore, a symmetrized generalization of this new form of poly-Genocchi polynomials that possesses a double generating function is introduced. Finally, the type 2 Apostolpoly-Genocchi polynomials with parameters a, b and c are defined using the concept of polyexponential function and several identities are derived, two of which show the connections of these polynomials with Stirling numbers of the first kind and the type 2 Apostol-type poly-Bernoulli polynomials.

In this paper, the superposition of ultrasonic signals which were generated by multi-source in a transformer was presented. For analysis of ultrasonic superposition, V$_{peak-peak}$ and pulse number of ultra-sonic signal were used. As a result, the wave form of ultrasonic superposition was classified into three types ; First type was the wave form whose V$_{peak-peak}$ was increased by the superposition of each signal's V$_{peak-peak}$. Second type was wave form whose V$_{peak-peak}$ was decreased by the superposition of each signal's V$_{peak-peak}$. And the other type was wave form whose peals were two or mere. And V$_{peak-peak}$ of superposed ultrasonic wave wads mostlv increased or decreased and pulse number of supe게osed u1trasonic wave was mostly increased.y increased.

The anionic exchange resins with the Dowex-1 and Amberlite CG-400 form were transformed into resin of sulfate and acetate acid form, respectively. The uranyl complex ions with SO$_{4}$$^{2-}$ and CH$_{3}$COO$^{-}$ were adsorbed on the anion exchange resion mentioned above, and these complex ions were eluted as mixture eluents of 0.7M HNO$_{3}$ - 0.5M NH$_{4}$NO$_{3}$ by anion exchange chromatography. The optimum adsorption conditions of uranyl anion complex ions adsorbed on the upper of the resin colmun were 1.5-2.0 ml/min of flow rates at pH 2.0 and adsorptive power of uranyl complex ion of sulfuric acid type were nearly consistent with the Caussion normal distribution curve, whereas the elution state of UO$_{2}$(Ac)$_{2}$$^{4-}$ with acetic acid type was departed. The weighing form obtained from resin of sulfuric acid and aceric acid type was U$_{3}$O$_{8}$ whose recovery was 91.7%. The possibility of recovering uranium from the monazite sulfate solution using a strong base anion resin, Amberlite CG-400(sulfate form), was successfully recovered more than 90%.
