Objective : I tried to turn out the fact that acupuncture treatment was originated from the sentences in "Yihapjinsaron of Somun(素問 離合眞邪論)". Method : I analyze the sentences in "Yihapjinsaron of Somun(素問 離合眞邪論)" by comparing the ponies on it and acupuncture books, Yi Ceon(李梴)'s "Medical beginner's book(醫學入門)". Conclusion : Making this research, I discovered Du Taesa(竇太師) primarily called it '14 finger strengthing-eliminating treatment methods(手指補瀉法)' in his book, "Acupuncture Guidance(鍼灸指南)" and he made full use of it in acupuncture clinic. Seo Bong(徐鳳) & Go Mu(高武) cited the 14 methods in their works, "Acupuncture Completement(鍼灸大全)" & "Acupuncture Essence(鍼灸節要聚英)", but they did not state their own views that this 14 methods ware derived from "Somun(素問)". Conclusion : I knew great acupuncture specialists and Yi Ceon(李梴) finally regarded the sentences in "Somun(素問)" as basic & complementary acupuncture techniques of "Acupuncture Guidance(鍼灸指南)" in their works. They hoped to let many acupuncture clinicians use the finger strengthing-eliminating treatment methods more often.

Aluminium and aluminium alloys have the high electrical and heat conductivity. It gives rise to difficulties for a choice of electrodes material for their contact electric welding. This paper describes the investigations performed to solve the above problem. The purpose of this investigation was to obtain dispersion-hardening alloys by the internal oxidation method, to optimize their contents and treatment modes, to produce electrodes of these alloys and to test them. The strengthing effect of alloys with oxide particles depends on their size stability at high temperatures. Despite of the fact, that oxides are the most stable of all the non-metallic phases their coagulation takes place. Based on the early results, we chose two types of alloys, first No. 1 Cu - 0,4%Al and second No. 2 Cu - 0,2%Be for production of electrodes. These alloys had not additional alloying elements. These alloys were prepared as 1 mm plates and flake-formed 200 m thick, and also No. 1 as a powder of size 100 mkm (received from Korea). The large samples for electrodes were produced by three methods : explosive welding method, dynamic one including the explosion compression of electrode blank and the quasi-dynamic method including the high-speed compression of dense briquest and the further hot extrusion of a rod.

This study investigates the bending behavior of a composite concrete slab roof with different methods of externally strengthing using steel plates and carbon fiber reinforced polymer (CFRP) strips. First, the concrete slab model which was reinforced with CFRP strips on the bottom surface of it is validated using experimental data, and then, using numerical modeling, 7 different models of square-shaped composite slab roofs are developed in ABAQUS software using the finite element modeling. Developed models include steel rebar reinforced concrete slab with variable thickness of CFRP and steel plates. Considering the control sample which has no external reinforcement, a set of 8 different reinforcement states has been investigated. Each of these 8 states is examined with 6 different uncertainties in terms of the properties of the materials in the construction of concrete slabs, which make 48 numerical models. In all models loading process is continued until complete failure occurs. The results from numerical investigations showed using the steel plates as an executive method for strengthening, the bending capacity of reinforced concrete slabs is increased in the ultimate bearing capacity of the slab by about 1.69 to 2.48 times. Also using CFRP strips, the increases in ultimate bearing capacity of the slab were about 1.61 to 2.36 times in different models with different material uncertainties.

This paper performs an experimental study on the flexural behavior of preloaded reinforced self-compacted concrete beams strengthened with carbon fiber reinforced polymers CFRP. A group of six preloaded strengthened beams was investigated along with one unstrengthened beam used as a reference beam RB. All beams have the same dimensions and reinforcement details: three beams are strengthened with CFRP laminates against flexural failure and three beams are strengthened with CFRP sheets. For simulating actual conditions, the beams are loaded before strengthening. Then, after strengthening, the beams are tested for flexural strength using 4-point loads where cracked and ultimate load and failure mode, along with load-deflection relation are recorded. To study the different configurations of strengthening, one layer, two layers, and U-wrap formation of laminates and sheets are considered. The results show that strengthing the RC beams using CFRP is an effective method to increase the beam's capacity by 47% up to 153% where deflection is reduced by 5%-80%. So, the beams strengthened with CFRP laminates have higher load capacity and lower ductility in comparison with the beams strengthened with CFRP sheets.

Obejective : Based on ${\ll}$sixty-ninth Nan${\gg}$ (${\ll}$難經${\cdot}$六十九難${\gg}$) the interpromoting of the five element's balance method to discuss following 'when deficiency than should strengthen mother and when excessive than eliminate son' theories. Method : This strengthening and eliminating method is based on Jang-bu organ's balance method when 'east is excessive (liver excessive (肝實 )) and west is deficiency (lung deficiency (肺虛))' then 'eliminate the south and strengthen the north's method. Results : The seventy-fifth Nan (${\ll}$難經${\cdot}$七十五難${\gg}$) explains' son effects mother's excessive and mother effects son's deficiency' theory where it balance method of the inter-overacting five elements controlling Jang-bu organ's differentiations. The eighty-first Nan (${\ll}$難經${\cdot}$八十一難${\gg}$) explains strengthening-eliminating method of 'lung excessive and liver deficiency.' Since there are two different perspective of seventy-fifth and eighty-first Nan, we must compare and discuss to make right point of view. Conclusion : the treatment method in ${\ll}$Nan kyoung sixty ninth nan${\gg}$ could be understood as a view of five element constitutional theory (五行體質理論), the treatment method in ${\ll}$Nan kyoung seventyty-fifth nan${\gg}$ of eleminating fire and strengthning water in case of liver excess and lung defficiency and the treatment method in ${\ll}$Nan kyoung eighty-first nan${\gg}$ of strengthning liver and eleminating lung in case of lung excess and liver defficiency could be understood as a view of the yin-yan constitutional theory (陰陽體質理論).

Carbon fiber reinforced polymer (CRFP) materials are well suited to the rehabilitation of civil engineering structures due to their corrosion resistance, high strength to weight ratio and high stiffness to weight ratio. Their application in the field of the rehabilitation of concrete structures is increased due to the vast number of bridges and buildings in need of strengthening. However, RC members, strengthened with externally bonded CFRP plates, happened to collapse before reaching the expected design failure load. Therefore, it is necessary to develop the new strengthening method to overcome the problems of previous bonded strengthening method. This problems can be solved by prestressing the CFRP plate before bonding to the concrete. In this study, a total of 21 specimens of 3.3 m length were tested by the four point bending method after strengthening them with externally bonded CFRP plates. The CFRP plates were bonded without prestress and with various prestress levels ranging from 0.4% to 0.8% of CFRP plate strain. All specimen with end anchorage failed by a plate fracture regardless of the prestress levels while the specimen without end anchorage failed by the separation of the plate from the beam due to premature debonding. The cracking loads was proportionally related to the prestress levels, but the maximum loads of specimens strengthened with prestressed CFRP plates were insignificantly affected by the prestress levels.
