김영준,박태열,최규환 東亞大學校附設스포츠科學硏究所 1999 스포츠科學硏究論文集 Vol.17 No.-

The purpose of this study was to investigate the distribution of the physical girth, muscular strength, Oxygen Consumption and pulmonary capacity by resistance Training. The subjects of this study were consisted with 10 adult males. The circuit of 10stations performed on 3 circuits, 3day/week. The subjects exercised at 60-70% of 1-RM, executing as many repetition as possible in 30sec, followed by 15sec rest as the subject moved to the rest station the training program. The result were as follow: 1. After resistance training was increases significantly in girth of upper arm, thigh, lower thigh. 2. After resistance training was increased significantly in grip strength, back strength, arm strength, leg strength. 3. After resistance training was increased significantly in HRmax, VEmax, but non-significantly VO₂max. It was concluded that resistance training are a good general conditioning activity, attends to more than one component of fitness.

정인원,김헌,홍주봉,지경환,이규영 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.6

연구목적 : 알코올 대사와 중추신경계내의 알코올 작용부위와 관련한 일부 후보유전자들이 알코올 의존과 관련이 있는지를 확인하고자 하였다. 방 법 : DSM-IV로 진단된 알코올 의존 환자 128명과 정상 대조군 128명을 대상으로 후보 유전자들의 다형성을 중합효소 연쇄반응과 제한효소처리법을 이용하여 동정하였다. 여기서 분리된 대립유전자와 유전자형에 따른 빈도의 차이를 유전자별로 각각 비교하였으며, 알코올 의존에 작용하는 서로 다른 유전자들에 의한 영향력을 배제하기 위하여 logistic regression 분석을 적용하였다. 결 과 : 알코올 의존군에서는 ALDH_2 유전자의 NN(wild type)형이 정상대조군에 비하여 유의하게 많았다(chi-square test, p<0.001). logistic regression analysis를 통하여 다른 유전자들에 의한 영향을 보정한 상태에서 ALDH_2가 NN(wild type)인 경우 다른 아형에 비하여 알코올 의존에 대한 odds ratio는 130.312이며 그 신뢰구간은 (17.22, 986.43)이었다. 한편, ASA는 N-glycosylation 부위에 변이형 대립유전자를 갖고 있는 경우(AG or GG)는 wild type에 비하여 알코올 의존에 대한 위험도는 2.344배이며 그 95% 신뢰구간은 (1.128, 4.871)이었다. 결 론 : 알코올 의존과 ALDH_2 유전자간에는 밀접한 연관성이 확인되었다. 또한 다른 유전자들은 개별 연관분석에서 의미있는 연관성이 관찰되지는 않았지만 logistic regression analysis를 통하여 N-glycosylation 부위에 다형성이 있는 ASA 유전자가 알코올 의존과 관련이 있음을 시사하였다. Objectives : This study was to explore the association between alcohol dependence and five candidate genes related to the metabolism of alcohol and the enzymes of the suspected sites in CNS. Methods : The genotype and allele frequencies of five candidate genes in 128 male hospitalized patients who met DSM-IV criteria for alcohol dependence were compared with 128 age-matched healthy male control subjects using polymerase chain reaction and restriction fragment length polymorphism. A logistic regression analysis was applied in order to exclude the reciprocal interactions among five candidate genes. Results : The NN genotype frequency of the ALDH_2 gene was significantly higher in alcoholic patients than in control subjects(chi-square test, p<0.001). No difference in frequency was found in the other four genes. In a logistic regression analysis, the odds ratio for alcohol dependence in the NN genotype of the ALDH_2 gene and AG or GG genotypes of the N glycosylation site on the ASA gene were 130.312(95% confidence interval, 17.22-986.43) and 2.344(95% confidence interval. 1.128-4.871), respectively. Conclusion : The result reiterates the association of the ALDH_2 gene polyporphism and the alcohol dependence. Logistic regression analysis additionally suggested that the N-glycosylation site on the ASA gene was associated with alcohol dependence.

Let D be an integral domain, X be an indeterminateover D, and D[X] be the polynomial ring over D.

Compactness of A Subspace of the Zariski Topology on SPEC(D)

( Gyu Whan Chang ) 호남수학회 2011 호남수학학술지 Vol.33 No.3

Let D be an integral domain, Spec(D) the set of prime ideals of D, and X a subspace of the Zariski topology on Spec(D). We show that X is compact if and only if given any ideal I of D with I □ P for all P ∈ X, there exists a finitely generated ideal J ⊆ I such that J □ P for all P ∈ X. We also prove that if D = ∩P∈X DP and if * is the star-operation on D induced by X, then X is compact if and only if *f-Max(D) ⊆ X. As a corollary, we have that t-Max(D) is compact and that P(D) = {P ∈ Spec(D)|P is minimal over (a : b) for some a,b in D} is compact if and only if t-Max(D) is contained ⊆ P(D).

We also prove that if D = ${\cap}_{P{\in}X}D_P$ and if * is the star-operation on D induced by X, then X is compact if and only if * $_f$-Max(D) ${\subseteq}$X. As a corollary, we have that t-Max(D) is compact and that ${\mathcal{P}}$(D) = {P${\in}$ Spec(D)$|$P is minimal over (a : b) for some a, b${\in}$D} is compact if and only if t-Max(D) ${\subseteq}\;{\mathcal{P}}$(D).

INTEGRAL DOMAINS WITH FINITELY MANY STAR OPERATIONS OF FINITE TYPE

Chang, Gyu Whan The Kangwon-Kyungki Mathematical Society 2012 한국수학논문집 Vol.20 No.2

Let D be an integral domain and SF(D) be the set of star operations of finite type on D. We show that if ${\mid}SF(D){\mid}$ < ${\infty}$, then every maximal ideal of D is a $t$-ideal. We give an example of integrally closed quasi-local domains D in which the maximal ideal is divisorial (so a $t$-ideal) but ${\mid}SF(D){\mid}={\infty}$. We also study the integrally closed domains D with ${\mid}SF(D){\mid}{\leq}2$.

THE IDEAL CLASS GROUP OF POLYNOMIAL OVERRINGS OF THE RING OF INTEGERS

Chang, Gyu Whan Korean Mathematical Society 2022 대한수학회지 Vol.59 No.3

Let D be an integral domain with quotient field K, Pic(D) be the ideal class group of D, and X be an indeterminate. A polynomial overring of D means a subring of K[X] containing D[X]. In this paper, we study almost Dedekind domains which are polynomial overrings of a principal ideal domain D, defined by the intersection of K[X] and rank-one discrete valuation rings with quotient field K(X), and their ideal class groups. Next, let ℤ be the ring of integers, ℚ be the field of rational numbers, and 𝔊_f be the set of finitely generated abelian groups (up to isomorphism). As an application, among other things, we show that there exists an overring R of ℤ[X] such that (i) R is a Bezout domain, (ii) R∩ℚ[X] is an almost Dedekind domain, (iii) Pic(R∩ℚ[X]) = $\oplus_{G{\in}G_{f}}$ G, (iv) for each G ∈ 𝔊_f, there is a multiplicative subset S of ℤ such that R_S ∩ ℚ[X] is a Dedekind domain with Pic(R_S ∩ ℚ[X]) = G, and (v) every invertible integral ideal I of R ∩ ℚ[X] can be written uniquely as I = XⁿQ^e₁₁···Q^e_k_k for some integer n ≥ 0, maximal ideals Q_i of R∩ℚ[X], and integers e_i ≠ 0. We also completely characterize the almost Dedekind polynomial overrings of ℤ containing Int(ℤ).

t-SPLITTING SETS S OF AN INTEGRAL DOMAIN D SUCH THAT D_S IS A FACTORIAL DOMAIN

Chang, Gyu Whan The Kangwon-Kyungki Mathematical Society 2013 한국수학논문집 Vol.21 No.4

Let D be an integral domain, S be a saturated multi-plicative subset of D such that $D_S$ is a factorial domain, $\{X_{\alpha}\}$ be a nonempty set of indeterminates, and $D[\{X_{\alpha}\}]$ be the polynomial ring over D. We show that S is a splitting (resp., almost splitting, t-splitting) set in D if and only if every nonzero prime t-ideal of D disjoint from S is principal (resp., contains a primary element, is t-invertible). We use this result to show that $D{\backslash}\{0\}$ is a splitting (resp., almost splitting, t-splitting) set in $D[\{X_{\alpha}\}]$ if and only if D is a GCD-domain (resp., UMT-domain with $Cl(D[\{X_{\alpha}\}]$ torsion UMT-domain).
