본 연구는 역대 대통령경호실장을 구분해 그들의 전문성과 권력성을 유형화하여 살펴봄으로써 성공한 대통령경호실장과 실패한 대통령경호실장의 원인을 알아보고, 미래의 대통령이 성공적으로 국정을 운영할 수 있도록 방향을 제공하여 주는데 그 목적이 있다. 역대 대통령경호실장을 유형화하기 위하여 경호업무에 오랜 기간 근무한 경호전문가 그룹을 대상으로 전문가회의를 통한 양적연구를 진행하였다. 이와 같은 연구 목적과 방법에 의한 연구결과는 다음과 같다. 첫째, 권력형/전문형은 제2대 박종규 대통령경호실장, 제5대 장세동 대통령경호실장, 제7대 이현우 대통령경호실장, 제8대 최석립 대통령경호실장 등 4명이 해당되었다. 둘째, 권력형/비전문형은 제1대 홍종철 대통령경호실장, 제3대 차지철 대통령경호실장, 제6대 안현태 대통령경호실장, 제14대 김인종 대통령실 경호처장 등 4명이 해당되었다. 셋째, 비권력형/전문형은 제4대 정동호 대통령경호실장, 제9대 박상범 대통령경호실장, 제13대 염상국 대통령경호실장 등 3명이 해당되었다. 넷째, 비권력형/비전문형은 제10대 김광석 대통령경호실장, 제11대 안주섭 대통령경호실장, 제12대 김세옥 대통령경호실장 등 3명이 해당되었다. 대통령경호실장의 유형화 연구는 앞으로 우리나라 대통령이 자신의 안전을 담당할 기관의 책임자를 임명할 때 성공하기 위한 준비된 대통령으로서 국가안보를 생각하고 전문성을 감안하여 국익을 위한 대통령경호실장을 임명해야 할 것을 시사하고 있다.

5종류의 수송배지를 흡수 및 배출 능력, 생존 효율, 회수율을 CLSI (Clinical and Laboratory Standards Institute) M40-A2의 Swab elution method (Quantitative) 기준으로 평가하였다. 액체배지가 반유동 배지보다 3가지 평가에서 대부분 우수한 결과값을 보여주었다. Flocked swab이 standard swab 형태보다 균의 흡수 및 배출의 능력 또한 우수하였다. 생존 효율에 대한 평가 결과는 액체배지(S4)가 가장 우수한 결과값을 보였다. 성장이 좋지 않은 S. pneumoniae는 액체배지(S4, S5)에서 생존효율과 회수율이 높았다. 균 회수율 평가 결과는 S. pyogenes는 모든 배지에서 CLSI 기준에 적합하였다. S. pneumoniae는 반유동 배지(S2, S3)에서 부적합하였고, 나머지 배지는 모두 기준에 적합하였다. H. influenzae는 반유동 배지(S1, S3)에서 부적합하였고, 반유동 배지(S2), 액체배지(S4, S5)에서 기준에 적합하였다. 호흡기 질환을 유발하는 S. pneumonia, H. influenzae의 생존 능력은 대부분의 배지에서 좋지 않았다. P. aeruginosa는 실온에서 과성장이 관찰되었다. 액체배지와 flocked swab의 조합이 3가지 평가 방법에서 가장 뛰어난 결과를 평가를 통해 확인하였다.

In this paper, we introduce the notions of fuzzy strongly (r, s)-preopen and preclosed mappings on intuitionistic fuzzy topological spaces in $\check{S}$ostak's sense. The relationships among fuzzy (r, s)-open, fuzzy strongly (r, s)-semiopen, fuzzy (r, s)-preopen, and fuzzy strongly (r, s)-preopen mappings are discussed. The characterizations for the fuzzy strongly (r, s)-preopen and preclosed mappings are obtained.

Let R be a commutative ring with identity and S a multiplicative subset of R. First, we introduce and study the u-S-projective dimension and u-S-injective dimension of an R-module, and then explore the u-S-global dimension u-S-gl.dim(R) of a commutative ring R, i.e., the supremum of u-S-projective dimensions of all R-modules. Finally, we investigate u-S-global dimensions of factor rings and polynomial rings.

Let A be a commutative integral domain with identity element and S a multiplicatively closed subset of A. In this paper, we introduce the concept of S-valuation domains as follows. The ring A is said to be an S-valuation domain if for every two ideals I and J of A, there exists s ∈ S such that either sI ⊆ J or sJ ⊆ I. We investigate some basic properties of S-valuation domains. Many examples and counterexamples are provided.

The purpose of this study was to examine: (1) how mothers generally react to children's negative emotions; (2) whether there were relationships between children's temperament and mothers' reactions to children's negative emotions; (3) whether there were relationships between mothers' depression and parenting stress, and their reactions to children's negative emotions; (4) whether there were relationships between mothers' reactions to children's negative emotions and children's behavior problems; and (5) whether there were relationships between mothers' reactions to children's negative emotions and children's social competence. The subjects were 246 preschoolers and their mothers. It was found that emotion-focused socialization and problem-focused socialization were the most frequently used reactions by mothers to cope with children's negative emotions. Relationships between children's temperament and mothers' reactions to children's negative emotions, those between mothers' depression and parenting stress and their reactions to children's negative emotions, those between mothers' reactions to children's negative emotions and children's behavior problems, and those between mothers' reactions to children's negative emotions and children's social competency were all partially significant. Sex differences were found in some of the relationships found significant.

Objective: The goal of this study was to clarify the differences in children's child care center adjustment depending on child-mother's goodness of fit. Methods: A total of 478 subjects, 239 dyads of 3 and 4 year old children and their mothers and 16 teachers participated in this study. The instruments used in this study were the DOTS-R, EAS Scale and PAQ. The collected data were analyzed using a t-test, Anova, and regression with the SPSS. Results: First, mother's demand was significantly different only with regard to the income level. Second, mother's temperament and mother's demand were positively correlated and the mother's demand was influenced by the mother's temperament. Third, mother's demand according to children's gender was indicated to differ significantly. Fourth, children's temperament and mother's demand were positively correlated and mother's demand was influenced by children's temperament. Finally, ego strength according to active and adoptive temperaments in child-mother's goodness of fit had significant differences. In addition, prosocial behavior according to regular temperament of child-mother's goodness of fit was indicated to have a significant difference. Conclusion/Implications: This study suggests that it is important for mothers to understand and appropriately demand the temperament of the children in the adaptation of the child care center.

The purposes of this study were to understand the buying patterns of adult women according to impulse shopping, benefits sought, and selecting information sources. This subjects of this study were 509 adult women from the age 20's to the age of 40's. This data were analyzed by using factor analysis multi regression analysis, analysis of variance, Scheffe' test. The results of this study were outlined as follow: 1. Differences among ages (the 20's, the 30's, and the 40's) in impulse shopping were as follow: The 30's bought more cosmetics to change their mood compared to the 20's or the 40's, and the 20's and the 30's bought more cosmetics matching to their images compared to the 40's. 2. From the aspects of benefits sought, the 20's and the 30's were more seriously consider the fame of brands compared to the 40's, showing they were different from the 40's. 3. From the aspects of selecting information sources about cosmetics, the 20's were more actively utilizing both human information sources and non-human information sources compared to the 30's and the 40's.

In [1], the authors generalize the concept of the class group of an integral domain $D(Cl_t(D))$ by introducing the notion of the S-class group of an integral domain where S is a multiplicative subset of D. The S-class group of D, $S-Cl_t(D)$, is the group of fractional t-invertible t-ideals of D under the t-multiplication modulo its subgroup of S-principal t-invertible t-ideals of D. In this paper we study when $S-Cl_t(D){\simeq}S-Cl_t(D_T)$, where T is a multiplicative subset generated by prime elements of D. We show that if D is a Mori domain, T a multiplicative subset generated by prime elements of D and S a multiplicative subset of D, then the natural homomorphism $S-Cl_t(D){\rightarrow}S-Cl_t(D_T)$ is an isomorphism. In particular, we give an S-version of Nagata's Theorem [13]: Let D be a Krull domain, T a multiplicative subset generated by prime elements of D and S another multiplicative subset of D. If $D_T$ is an S-factorial domain, then D is an S-factorial domain.
