A measure for good products manufactured by grinding process is the surface roughness that is affected by a lot of operating parameters such as types of abrasive, grain size, bond material, wheel speed, table speed, depth of cut, hardness of workpiece and stiffness of grinding machine. In this study, an application of the design of experiments was tried for evaluating the effect of operating parameters on the surface roughness. The workpiece was a high speed tool steel(SKH5I) and the surface grinding was conducted. In order to obtain the best surface roughness within constraints of the working range, the optimal grinding conditions were selected. The usefulness of this method was evaluated by the statistical strategy.
TRANSITIVE SETS WITH DOMINATED SPLITTING
Man seob Lee 충청수학회 2010 충청수학회지 Vol.23 No.1
Let be a transitive set for f. In this paper, we show that if a f-invariant set has the C1-stably shadowing property, then admits a dominated splitting.
C<sup>2</sup> DIFFEOMORPHISMS WITH THE INVERSE SHADOWING PROPERTY
Lee, Man-Seob Korean Mathematical Society 2010 대한수학회논문집 Vol.25 No.2
Let f be a $C^2$-diffeomorphism on a closed surface which satisfies the Axiom A. Then f is in the $C^2$-interior of the set of all diffeomorphisms having the inverse shadowing property with respect to the class of the continuous methods if and only if f satisfies the strong transversality condition.
C<sup>1</sup>-STABLE INVERSE SHADOWING CHAIN COMPONENTS FOR GENERIC DIFFEOMORPHISMS
Lee, Man-Seob Korean Mathematical Society 2009 대한수학회논문집 Vol.24 No.1
Let f be a diffeomorphism of a compact $C^{\infty}$ manifold, and let p be a hyperbolic periodic point of f. In this paper we introduce the notion of $C^1$-stable inverse shadowing for a closed f-invariant set, and prove that (i) the chain recurrent set $\cal{R}(f)$ of f has $C^1$-stable inverse shadowing property if and only if f satisfies both Axiom A and no-cycle condition, (ii) $C^1$-generically, the chain component $C_f(p)$ of f associated to p is hyperbolic if and only if $C_f(p)$ has the $C^1$-stable inverse shadowing property.
TAME DIFFEOMORPHISMS WITH C1-STABLE PROPERTIES
Man seob Lee 충청수학회 2008 충청수학회지 Vol.21 No.4
Let f be a di??eomorphisms of a compact C1 manifold, and let p be a hyperbolic periodic point of f. In this paper, we prove that if generically, f is tame di??eomor- phims then the following conditions are equivalent: (i) f is-stable, (ii)f has the C1-stable shadowing property (iii) f has the C1-stable inverse shadowing property.
DIFFEOMORPHISMS WITH THE STABLY ASYMPTOTIC AVERAGE SHADOWING PROPERTY
Man seob Lee 충청수학회 2010 충청수학회지 Vol.23 No.4
Let p be a hyperbolic periodic point of f; and let ¤(p) be a closed set which containing p: In this paper, we show that C1- generically, if fj¤(p) has the C1-stably asymptotic average shadow- ing property, then it admits a dominated splitting.
LIMIT WEAK SHADOWABLE TRANSITIVE SETS OF C<sup>1</sup>-GENERIC DIFFEOMORPHISMS
Lee, Man-Seob,Lu, Gang Korean Mathematical Society 2012 대한수학회논문집 Vol.27 No.3
In this paper, we prove that locally maximal transitive set of a $C^1$-generic diffeomorphism is hyperbolic if and only if it is limit weak shadowable.

Allergic rhinitis comes within snuffle in Chinese medicine. For generations, physicians have believed that the internal factors that cause this disease are pulmonary tuberculosis, splenic hypofunction and loss of virility, and its external factors are a cold, an uncommon atmosphere and an uncommon flavor. From the viewpoint of Chinese medicine, this symptom was fundamentally cured by "abidance by individuality, locality and seasons", on the basis of demonstration. In result, visceral function was recovered. In Chinese medicine, a disease is etiologically cured by the principles of Wholism and by discriminating among symptoms. In particular, "method for replenishing Qi and securing Exterior" has been widely used among the foregoing therapeutics. According to modern pharmacology, Astragli Radix, Atractylodis Macrocephalae Rhizoma and Ledebouriellae Radix all have antihistaminic effects and strengthen of the masticating and swallowing function of the recticuloendothelial system. This disease can be cured by controlling immunity and allergic reactions. Besides, it is necessary to take moderate exercise, to strengthen constitution, to avoid causative substances, to control ingesting flesh, meat and shrimps, to eat little, and to avoid what is cold and raw.
A review of atopic dermatitis in traditional Chinese medicine
Lee, Sang-Chang,Lee, Young-Seob,Seong, Man-Jun,Choi, Mi-Sun,Kang, Suk-Hoon,Lee, Sheng-Ho,Kim, Jong-Hak,Kim, Min-San,Kwon, Dong-Yeul 대한한약학회 2008 Journal of oriental pharmacy Vol.1 No.2
Herbal medicines have an accurate effect on atopic dermatitis, and at the same time, they hardly have adverse reactions. However, herbal medicines are difficult to be quantitatively analyzed due to low-quality preparation and types. In addition, herbal medicines have raised many problems as they have not been standardized and their active components have not been analyzed. Patients with atopic dermatitis began to recognize the effectivity and safety of herbal medicines. Accordingly, standardization, biological analyses, animal experiments and clinical trials should be generally performed in order that herbal medicines may be recognized all over the world. A standard, which is to objectively judge the curative effect of atopic dermatitis, should be established as soon as possible. Case studies and RCTs (Randomized Controlled Trials) should be actively performed on the basis of rigid clinical trial design to the end that the curative effect of herbal medicines is recognized all the world over.
