With a rapid expansion of the elderly population, there is a greater demand for the construction of senior complexes. However, due to a land price increase and insufficient financial resources, accommodating such a demand is challenging. Also, as aging progresses, many elderlies tend to be isolated from local community, because of deteriorating health. As a result, constructing senior complexes is becoming an important community project. The construction of senior complexes in Korea has been started since early 2000, so it is still in the beginning stage in Korea. However, in the case of Japan, they have more experience in building such buildings. Therefore, in this study, 49 senior complexes in Japan were analysed, and the following spatial characteristics were derived. 1. By classifying senior complexes largely into a complex type with similar facilities and a complex type with different facilities, 12 types were derived. Depending on the types of facilities, basic sharing rooms and selectively sharing rooms by need are suggested. 2. Depending on 4 characteristics, such as spatial composition, entrance type, circulation form, and complex facility type, 17 types of senior complexes were derived, and the characteristics of each type are presented.

This paper proposes a new IFFT(Inverse Fast Fourier Transform) algorithm, which is proper for IMDCT(Inverse Modified Discrete Cosine Transform) of MPEG-2 AAC(Advanced Audio Coding) decoder. The $2^n$(N-point) type IMDCT is the most powerful among many IMDCT algorithms, however it includes IFFT that requires many calculation cycles. The IFFT used in $2^n$(N-point) type IMDCT employ the bit-reverse data arrangement of inputs and N/4-point complex IFFT to reduce the calculation cycles. We devised a new data arrangement method of IFFT input and $N/4^{n+1}$-type IFFT and thus we can reduce multiplication cycles, addition cycles, and ROM size.

The aim of this study was to investigate the effect of complex Korean medicine treatment especially Buja-tang and Aconitum ciliare decaisne pharmacopuncture on patients with type 1 complex regional pain syndrome caused after a traffic accident. The patients was treated with Buja-tang, Aconitum ciliare decaisne pharmacupuncture, acupuncture and physical therapy during 20 days of hospitalization. Numerical rating scale (NRS), short form McGill pain questionnaire (SF-MPQ), body temperature measurement of the foot, manual muscle test (MMT) were used for assessment. After treatments, NRS of burning pain in the left ankle decreased from 8 to 4-5 and NRS of burning pain in the right ankle decreased from 7 to 4-5. Also, SF-MPQ results, foot temperature measurement and MMT showed improvement during hospitalization. This study shows that complex Korean medicine treatment especially Buja-tang and Aconitum ciliare decaisne pharmacopuncture are effective in alleviating symptoms in patients with type 1 complex regional pain syndrome.

This study was carried out to present the measures for the stable environment-friendly rice's production, farm income increase and consumption revitalization and so on by analyzing economic effects of the environment-friendly rice's production complex by certification type, cultivation type and distribution type. Data were collected from the environment-friendly rice's production complex in Kyunggi, Kangwon, Chungnam and Chunnam provinces. Survey was conducted with sorted by organic and no-pesticide farming. Of the samples 5 types of organic farming and 4 types of no-pesticide farming were surveyed in 17 and 18 complex, respectively. The farmers income of organic and no-pesticide farming per 10a were individually about $29{\sim}68%$ and 50% higher than the conventional farming. Base on the above results, the reasonable measures fur the stable environment-friendly rice's production and distribution and consumption revitalization were to secure partnership among business, universities, government and research institutes sectors, to organize farmers group and production complex, to establish RPC for environment-friendly rice and to introduce certification system for the distribution dealers.

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%.

Let M be a real hypersurface of a complex space form with almost contact metric structure (${\phi}$, ${\xi}$, ${\eta}$, g). In this paper, we study real hypersurfaces in a complex space form whose structure Jacobi operator $R_{\xi}=R({\cdot},\;{\xi}){\xi}$ is ${\xi}$-parallel. In particular, we prove that the condition ${\nabla}_{\xi}R_{\xi}=0$ characterizes the homogeneous real hypersurfaces of type A in a complex projective space or a complex hyperbolic space when $R_{\xi}{\phi}S=R_{\xi}S{\phi}$ holds on M, where S denotes the Ricci tensor of type (1,1) on M.

This study aims to investigate the energy performance of apartment in respect of complex design, building type and generation house layout and finally to produce the guide line for energy saving design. To grasp the present condition and problem about this subject, apartment building types were examined and representative types were extracted. Considering azimuth angle, private area, and generation number, building type of the subject apartment was classified in detail, energy simulation was conducted, and the effect to energy cost was compared. In the research, using VE energy simulation program, the heating and cooling load were calculated and converted to energy cost. It is expected that this analysed results will be basic data for the more integrated study. Research consequence can be summarized as follow: 1) Energy cost is compared according to several azimuth in plank '一' type apartment. As the results, calculated gas cost is the best in $49^{\circ}$, but total cost is in $-31^{\circ}$. 2) Apartment buildings of tower types are compared, it is resulted that 'Y' type (azimuth $-7^{\circ}$, $-20^{\circ}$) is the best in gas cost, but the total cost is worst because of high cooling load.
