Ijema's four constitution theory is the result of creative succession which is originated from the "Hwangjenaegyeong(黃帝內經)", and shaped up as "Sanghanron(傷寒論)", the key of Ijema's theory would be the re-explnation of the Sameum-Samyang pattern identification. therefore, we should recognize that the four constitution theory is related to the Sameum-Samyang identification of "Sanghanron(傷寒論)". And is even on the mutual supporting relation. from this point of view, the "Dong-uisusebowon(東醫壽世保元)" could be valuated as a commentary of "Sanghanron(傷寒論)" which shows us that how to review the Sameum-Samyang identification as the point of characteristic of four constitution theory.

This study was conducted to grasp the effect of afforestation of cut slope using coir blocks on the improvement of scenery and the management of non point pollution source. Total four experimental tanks such as general soil slope, coir blocks, installation slope, slope refilling the inside of coir blocks slope with pebble, slope refilling the inside of coir blocks with soil and plant were installed, pollution source water was supplied and the possibility of reduction management of non point pollution source was analyzed at four items of COD, SS, T-N, T-P and main results drawn from this study are as follows. In conclusion, biodegradable materials like coir blocks and soil and plant layers are judged to be helpful in reduction management of non point pollution source inflowing to water space from land area. Thus, the reduction of non point pollution source occurring at land area is thought to be fully controlled at the cut slope, the space prior to inflowing to water ecological space like a stream or a swamp area.

Objective: The purpose of the study was to examine the effects of a five-week auricular acupressure (AA) program on smoking cessation for male high school students.Methods: From May 27 2015 to November 18 2015, this study investigated 66 high school students who had been smoking. More than four sessions of AA were given to participants, and surveys were conducted before each treatment. Once a week, the AA was administered at the endocrine point, lung point, throat point, nasal fossae point, bronchial tube point, and mouth point.Result: Thirty-four (51.5%) students reduced their number of cigarettes smoked per day, while 17 (25.7%) students complained of side effects.Conclusions: Results show that AA is generally effective, and side effects occur less often than with anti-smoking acupuncture. So AA could be preferred on smoking cessation for students.

In this paper we prove common fixed point theorems for four mappings, under the condition of weakly compatible mappings in Menger spaces, without taking any function continuous. We improve results of [A common fixed point theorem for three mappings on Menger spaces. Math. Japan. 34 (1989), no. 6, 919-923], [On common fixed point theorems of compatible mappings in Menger spaces. Demonstratio Math. 31 (1998), no. 3, 537-546].

PURPOSE. To evaluate the effects of different surface treatments on the bond strength of novel CAD/CAM restorative materials to resin cement by four point bending test. MATERIALS AND METHODS. The CAD/CAM materials under investigation were e.max CAD, Mark II, Lava Ultimate, and Enamic. A total of 400 bar specimens ($4{\times}1.2{\times}12mm$) (n=10) milled from the CAD/CAM blocks underwent various pretreatments (no pretreatment (C), hydrofluoric acid (A), hydrofluoric acid + universal adhesive (Scotchbond) (AS), sandblasting (Sb), and sandblasting + universal adhesive (SbS)). The bars were luted end-to-end on the prepared surfaces with a dual curing adhesive resin cement (Variolink N, Ivoclar Vivadent) on the custom-made stainless steel mold. Ten test specimens for each treatment and material combination were performed with four point bending test method. Data were analyzed using ANOVA and Tukey's test. RESULTS. The surface treatment and type of CAD/CAM restorative material showed a significant effect on the four point bending strength (FPBS) (P<.001). For LDC, AS surface treatment showed the highest FPBS results ($100.31{\pm}10.7MPa$) and the lowest values were obtained in RNC ($23.63{\pm}9.0MPa$) for control group. SEM analyses showed that the surface topography of CAD/CAM restorative materials was modified after treatments. CONCLUSION. The surface treatment of sandblasting or HF acid etching in combination with a universal adhesive containing MDP can be suggested for the adhesive cementation of the novel CAD/CAM restorative materials.

본 논문은 높은 데이터 처리율을 요하는 MIMO-OFDM 시스템을 위하여 고속의 낮은 하드웨어 복잡도를 가진 128/64-point $radix-2^4$ FFT/IFFT 프로세서 설계에 대해 제안한다. 높은 Radix 다중경로 지연 피드백 (MDF) FFT구조는 고속의 데이터 처리율과 낮은 하드웨어 복잡도를 제공한다. 제안하는 프로세서는 128-point와 64 Point FFT/IFFT의 동작을 지원할 뿐만 아니라 4-병렬 데이터 경로를 사용함으로써 높은 데이터 처리율을 지원한다. 또한, 제안하는 프로세서는 기존의 128/64-point FFT/IFFT 프로세서에 비해 낮은 하드웨어 복잡도를 지닌다. 제안된 FFT/IFFT 프로세서는 IEEE 802.11n 표준의 요구사항을 만족시키며 140MHz 클락 속도에서 560MSample/s의 높은 데이터 처리율을 가진다.

We establish a coincidence and a common fixed point result for four mappings involving a (${\psi}$, ${\varphi}$)-weak contractive condition type on a complete metric space. We take on ${\psi}$ and ${\varphi}$ the same conditions given by Popescu [Fixed points for (${\psi}$, ${\varphi}$)-weak contractions, Appl. Math. Lett. 24 (2011), 1-4].

In this paper, we establish common fixed point theorem for type(${\beta}$) compatible four mappings with implicit relations defined on an intuitionistic fuzzy metric space. Also, we present the example of common fixed point satisfying the conditions of main theorem in an intuitionistic fuzzy metric space.

We developed a robot that has four limbs, each of which has the same kinematic structure and has 6 degrees of freedom. The robot is 600mm high and weighs 4.3kg. The robot can perform walking and manipulating task by using the four limbs selectively. The robot has three walking patterns. The first one is biped walking, which uses two rear limbs as legs and two front limbs as arms. The second one is biped walking with supporting arms, which is basically biped walking but uses two arms as supporting legs for increasing stability of the robot. The last one is quadruped walking, which uses all the four limbs as legs. When a task for the robot is given, the robot approaches the task point by selecting an appropriate walking pattern among three walking patterns and performs the task. The robot has many degrees of freedom and is a redundant system for a three dimensional task. We propose a redundancy resolution method, in which the robot’s translational move to the task point is modeled as a prismatic joint and optimal solutions are obtained by optimizing some performance criteria. Several simulations are performed for the validity of the proposed method.
