The purpose of this study was 1) to understand the job transfer in education & training(E&T) programs & organizational situational characteristics, and 2) to analyze the effects of the E&T programs & organizational situational characteristic groups on each of the levels of job transfer. There is intimate relationship between E&T programs characteristics & organizational situational characteristics and job transfer, so we can't think of them separately. With this point of view the most frequently discussed problem is how to apply the theory in actual job, but in reality it's true that the improvement of job transfer can't reach the expectations of the E&T programs. In literature view study, the concepts of job transfer in E&T, the general theory on E&T, and the actual condition and points at issue of the existing E&T practices in the medium and small-sized hospitals were defined. As the results from empirical analysis, we could find followings: First, in evaluation of the job transfer, demographic characteristics (seniority, occupational category, position) variables have a significant different. Second, in degree of the job transfer, E&T programs characteristics(contents of E&T, design of E&T, conditions of E&T, teaching ability of lecturer, methods of E&T) variables have a different influence upon each of the evaluation levels of E&T. Third, support of CEO variables have a different influence on the job transfer according to contents, design, conditions of the E&T programs. Fourth, support of co-works variables have a different influence on the job transfer according to design, conditions, method of the E&T programs. Fifty, support of organizational atmosphere variables have a different influence on the job transfer according to contents, design, conditions of the E&T programs.

HPV-16형의 염기배열 변이는 지역적, 인종적으로 특징적인 차이가 있으며 특히 HPV-16형 E6/E7 유전자의 특정 염기 서열변이는 자궁경부암 및 자궁상피내 신생종양물의 발생을 일으키는 고위험 요인으로 알려져 있다. 본 연구는 2007년 부산지역 유흥업소 종사여성으로 분리된 HPV-16형 19건을 대상으로 E6/E7 유전자 영역(nt 34-880)을 표적으로 지역적 염기 서열 변이를 조사하였다. nucleotide 수준에서 HPV16형 E6 유전자는 T178G (n=11), T178A (n=1), T350G (n=4), A442C (n=2), A104T, A111G, C116T, G145T, T183G, C335T, G522C 등 11종의 변이주가 발견되었고, E7 유전자는 A647G (n=12), A645C, A777C, G663A, T732C, T760C, A775T, T789C, T795G 등 9종의 변이주가 발견되었다. 아미노산 수준에서는 HPV-16형 E6 단백질의 경우 D25E (n=12), L83V (n=4), E113D (n=2), MIL, Q3R, P5S, Q14H, D25N, 127R, H78Y, C140S 등 11종의 변이주를, HPV16형 E7 단백질의 경우 N29S (n=12), L28F, T72S 등 3종의 변이주를 관찰할 수 있었다. 본 연구 결과, 부산지역의 HPV-16형 E6/E7 우점 돌연변이주는 E6 D25E (75%), E7 N29S (78%)로 각각 나타났다. 앞으로 자궁경부암 환자 및 일반여성을 포함한 더 많은 모집 단을 대상으로 HPV-16형 E6/E7의 intratypic variants를 비교 조사하여 실제 HPV-16형 E6/E7 어떤 변이주가 자궁경부암 유발 위험성과의 관련성은 더 많이 연구되어져야 할 것으로 사료된다.

Let ($X, \Beta, \mu$) be a measure space with the $\sigma$-algebra $\Beta$ and the probability measure $\mu$. Throughouth this article set equalities and inclusions are understood as being so modulo measure zero sets. A transformation T defined on a probability space X is said to be measure preserving if $\mu(T^{-1}E) = \mu(E)$ for $E \in B$. It is said to be ergodic if $\mu(E) = 0$ or i whenever $T^{-1}E = E$ for $E \in B$. Consider the sequence ${x, Tx, T^2x,...}$ for $x \in X$. One may ask the following questions: What is the relative frequency of the points $T^nx$ which visit the set E\ulcorner Birkhoff Ergodic Theorem states that for an ergodic transformation T the time average $lim_{n \to \infty}(1/N)\sum^{N-1}_{n=0}{f(T^nx)}$ equals for almost every x the space average $(1/\mu(X)) \int_X f(x)d\mu(x)$. In the special case when f is the characteristic function $\chi E$ of a set E and T is ergodic we have the following formula for the frequency of visits of T-iterates to E : $$ lim_{N \to \infty} \frac{$\mid${n : T^n x \in E, 0 \leq n $\mid$}{N} = \mu(E) $$ for almost all $x \in X$ where $$\mid$\cdot$\mid$$ denotes cardinality of a set. For the details, see [8], [10].

Let C[0, T] denote a generalized analogue of Wiener space, the space of real-valued continuous functions on the interval [0, T]. Define $Z_{\vec{e},n}$ : C[0, T] → ℝⁿ⁺¹ by $$Z_{\vec{e},n}(x)=\(x(0),\;{\int}_0^T\;e_1(t)dx(t),{\cdots},\;{\int}_0^T\;e_n(t)dx(t)\)$$, where e₁,…, e_n are of bounded variations on [0, T]. In this paper we derive a simple evaluation formula for Radon-Nikodym derivatives similar to the conditional expectations of functions on C[0, T] with the conditioning function $Z_{\vec{e},n}$ which has an initial weight and a kind of drift. As applications of the formula, we evaluate the Radon-Nikodym derivatives of various functions on C[0, T] which are of interested in Feynman integration theory and quantum mechanics. This work generalizes and simplifies the existing results, that is, the simple formulas with the conditioning functions related to the partitions of time interval [0, T].

최근 학제 간 융합이 관심을 받고 있다. 특히 예술과 기술의 학제 간 연구는 매우 흥미로운 주제이다. E.A.T.는 1966년 뉴욕에서 예술가와 공학자에 의해 설립되었다. 본 연구는 E.A.T. 사례를 중심으로 예술과 기술이 융합될 수 있었던 시대적 배경과 E.A.T.의 작품 특성을 분석하였다. 시대적 배경에 대한 분석결과 5가지 요인들이 E.A.T.가 조직되고 발전되는 데 있어 영향을 미쳤음을 발견하였다. 경제적 요인, 예술적 요인, 기술적 요인, 교육적 요인, 그리고 후원 문화적 요인이 예술과 기술의 융합에 영향을 미쳤다. 예술가와 공학자가 협업한 E.A.T. 작품은 일반적으로 세 가지 특성을 가지고 있었다. 다양한 분야를 아우르는 융합성, 여러 가지 감각을 활용하는 다감각성, 그리고 환경과 인간에 대한 상호작용성이 E.A.T. 작품에 나타났다. 본 연구는 예술적 표현의 한계를 극복하고 새로운 기술을 개발하고자 하는 예술가와 공학자 모두에게 의미 있는 함의를 제공한다.

For n ≥ 2 and a real Banach space E, 𝓛(ⁿE : E) denotes the space of all continuous n-linear mappings from E to itself. Let Π (E) = {[x^*, (x₁, . . . , x_n)] : x^*(x_j) = ||x^*|| = ||x_j|| = 1 for j = 1, . . . , n }. An element [x^*, (x₁, . . . , x_n)] ∈ Π(E) is called a numerical radius point of T ∈ 𝓛(ⁿE : E) if |x^*(T(x₁, . . . , x_n))| = v(T), where the numerical radius v(T) = sup_{[y^*,y1,...,yn]∈Π(E)}|y^*(T(y₁, . . . , y_n))|. For T ∈ 𝓛(ⁿE : E), we define Nradius(T) = {[x^*, (x₁, . . . , x_n)] ∈ Π(E) : [x^*, (x₁, . . . , x_n)] is a numerical radius point of T}. T is called a numerical radius peak n-linear mapping if there is a unique [x^*, (x₁, . . . , x_n)] ∈ Π(E) such that Nradius(T) = {±[x^*, (x₁, . . . , x_n)]}. In this paper we present explicit formulae for the numerical radius of T for every T ∈ 𝓛(ⁿE : E) for E = c₀ or l_∞. Using these formulae we show that there are no numerical radius peak mappings of 𝓛(ⁿc₀ : c₀).

Growth curves in Hanwoo steers were estimated by Gompertz, Von Bertalanffy, Logistic, and Brody nonlinear models using growth data collected by the Hanwoo Improvement Center from a total of 6,973 Hanwoo (Bos taurus coreanae) steers 6 to 24 months old that were born between 1996 and 2015. The data included three parameters: A, mature size of body measurement; b, growth ratio; and, k, intrinsic growth rate. Nonlinear regression equations for wither height according to Gompertz, Von Bertalanffy, Logistic, and Brody models were $Y_t=144.7e^{-0.5869e^{-0.00301t}}$, $Y_t=145.3(1-0.1816e^{-0.00284t})^3$, $Y_t=143.1(1+0.7356e^{-0.00352t})^{-1}$, and $Y_t=146.8(1+0.4700e^{-0.00249t})^1$, respectively, while those for hip height were $Y_t=144.5e^{-0.5549e^{-0.00312t}}$, $Y_t=145.0(1-0.1724e^{-0.00295t})^3$, $Y_t=143.1(1+0.6863e^{-0.00360t})^{-1}$, and $Y_t=146.2(1+0.4501e^{-0.00263t})^1$, respectively. Equations for body length $Y_t=174.1e^{-0.8342e^{-0.00289t}}$, $Y_t=175.8(1-0.2500e^{-0.00265t})^3$, $Y_t=170.0(1+1.1548e^{-0.00363t})^{-1}$, and $Y_t=180.3(1+0.6077e^{-0.00215t})^1$, respectively, for the same models. Among the four models, the Brody model resulted in the lowest mean square error, with mean square errors of 31.79, 30.57, and 42.13, respectively, for wither height, hip height, and body length. Also, an estimated birth wither height, birth hip height, and birth body length (77.98, 80.57, and 70.97 cm, respectively) were lower in the Brody model than in other models. An inflection point was not observed during the growth phase of Hanwoo steer according to the growth curves calculated using Gompertz, Von Bertalanffy, and Logistic models. Based on the results, we concluded that the regression equation using the Brody model was the most appropriate among the four growth models. To obtain more accurate parameters, however, using data from a wider production period (from birth to shipping) would be required, and the development of a suitable model for body conformation traits would be needed.
