Product involvement is an important factor in consumer evaluation of co-branding. However, academic discussions over this factor have largely been neglected. This paper bridges this gap and investigates how product involvement moderates the strength of the reciprocal effect on each brand partner. We validate two theory-driven propositions by using a theoretical modeling approach. Proposition 1 explains that the negative reciprocal effect on partnering brands is stronger in the scenario of higher-involved categories than in lower-involved categories. Proposition 2 argues that the positive reciprocal effect on partnering brands can be more significant in the case of lower-involved categories than in higher-involved categories. To the best of our knowledge, we are the first to explore the influence of product involvement on reciprocal effects in the scenario of a moderately-incongruent co-branding alliance.

Purpose: This study was to find a correlation between the bilateral reciprocal leg press test and a the balance in chronic stroke patients. Methods: Eighteen patients performed an isokinetic leg press test consisting of a bilateral reciprocal and unilateral mode. Following the isokinetic leg press testing, subjects performed the balance test: Berg Balance Scale (BBS), Timed Up & Go (TUG) test, and stability limit. Pearson product moment correlation coefficients were used to determine the correlation between the mean score of the isokinetic leg press test, balance test in both affected and non-affected side. Results: This study indicated a significant correlation between the bilateral reciprocal leg press test and stability limit. There were significant correlation between non-affected side bilateral leg press(NBL) and BBS (r=0.501), affected side bilateral leg press (ABL) and non-affected side stability limit(NS) (r=0.614), ABL and total stability limit (TS) (r=0.493), NBL and affected side stability limit(AS) (r=0.480), NBL and NS (r=0.560), NBL and TS (r=0.563), among the patients. Conclusion: Measurement of the lower extremity strength using the bilateral reciprocal leg press test can be used as an evaluating tool of the balance test.

본 연구에서는 추격 브랜드확장 상황에서 선행 브랜드확장과 추격 브랜드확장의 시장성과가 추격확장제품의 모브랜드에 미치는 반향효과에 대해 살펴보았다. 이를 위해 2(선행 브랜드확장의 시장성과: 성공/실패)${\times}$2(추격 브랜드확장의 시장성과: 성공/실패) 집단간 실험설계를 적용하였다. 가설검증은 이원분산분석(2-Way ANOVA)을 통해 이루어졌다. 그 결과, 추격 브랜드확장이 성공했을 경우 추격확장제품의 모브랜드에 대한 평가는 선행 브랜드확장이 실패했을 때 더 긍정적이었다. 하지만 추격 브랜드확장이 실패했을 경우 추격확장제품의 모브랜드에 대한 평가는 선행 브랜드확장이 성공했을 때 더 부정적인 것으로 나타났다.

The efficiency of photosensitization of methyl linoleate (ML) oxidation by N-acetyl-L-trypophan(NAT) and 3-methyl indole(scatole) was markedly enhanced by increased concentration of ML in ethanol solution. The fluorescence intensities of sensitizers were observed to be quenched by ML, indicating that ML interacts with the indole excited singlet state. The inhibition of photosensitization by azide demonstrated a possible role of singlet oxygen in the photosensitization. The steady state kinetic treatment of azide inhibition of photosensitization was expected to show linear increase of reciprocal yield of ML oxidation product vs. reciprocal ML concentration at constant azide concentration, but the actual slope was nonlinear. This indicates another competing reaction involved in the photosensitization, As a possible competing reaction, electron transfer from ML to the excited sensitizer was proposed, since the measured fluorescence quenching rate constant closely resembled electron transfer rate constant determined from ML concentration dependence of oxidation product formation.

분수 나눗셈의 여러 맥락 중 등분제와 카테시안 곱의 역 맥락에서는 제수의 역수 곱하기 알고리즘이 자연스럽게 유도된다. 그러므로 제수의 역수 곱하기 알고리즘을 분수 나눗셈의 통합 알고리즘으로 지도하고자 할 때 특히 이슈가 되는 것은 포함제 맥락이다. 이 논문에서는 포함제 맥락에서 $1{\div}$(제수)를 매개로 하는 방법이 지닌 잠재력 및 그 기반을 분석하고, 이 방법을 제수의 역수 곱하기 알고리즘을 분수 나눗셈의 통합 알고리즘으로 지도하려 할 때 고려할 수 있는 한 대안으로 제안한다. 포함제 맥락에서 $1{\div}$(제수)를 매개로 하여 제수의 역수 곱하기 알고리즘을 유도하는 방법은 다음과 같은 특징을 지니고 있다. 첫째, 포함제 맥락에서 맥락과의 연결성을 유지한 채로 제수의 역수 곱하기 알고리즘을 유도할 수 있다. 둘째, 다른 맥락들에서와 마찬가지로, 제수와 1의 곱셈적 관계에 주목한다. 셋째, 다른 맥락들에서와 마찬가지로, 제수와 1의 곱셈적 관계를 1/제수의 분모을 징검다리로 삼는 추론과 제수의 분자를 징검다리로 삼는 두 가지 추론으로 파악한다. 이러한 특징은 이 방법이 제수의 역수 곱하기 알고리즘을 분수 나눗셈의 공통 구조를 담고 있는 통합 알고리즘으로 다루는 데 기여할 수 있음을 시사한다. 한편, 이 방법은 양분수의 이중적 의미와 배의 합성을 그 기반으로 한다. 분수 나눗셈의 통합적 이해를 지향하는 교재 개발 및 수업 연구에서는 이 기반의 형성에 유의할 필요가 있다.

This paper describes a comprehensive approach to examine how technological innovation contributes to the renewal of the firm's competences through its dynamic and reciprocal relationship with R&D and product commercialization. Three theories of technology and innovation (R&D and technological knowledge concept, product-process concept, technological interdependence concept) are used to relate technology and innovation to strategic management. Based on those theories, this paper attempts to identify dynamic relationship between product innovation and process innovation by system dynamics, by investigating the aspect of the dynamic changes of the closed feedback circulation structure in which R&D investments drive technological knowledge accumulation, and such knowledge accumulation actualizes product innovation and process innovation, subsequently resulting in the increase of productivity, customer satisfaction, profit generation, and re-investment on R&D from the created profits. This provides the ability to assess the advantages and disadvantages of different technological innovation strategies and commitments, and the opportunity to explore equilibrium point and suggest a generalized technological innovation model under different industry environment parameters and time-strategies.

For each real number $n$ > 6, we prove that there is a sequence $\{pk(n,z)\}^{\infty}_{k=1}$ of fourth degree self-reciprocal polynomials such that the zeros of $p_k(n,z)$ are all simple and real, and every $p_{k+1}(n,z)$ has the largest (in modulus) zero ${\alpha}{\beta}$ where ${\alpha}$ and ${\beta}$ are the first and the second largest (in modulus) zeros of $p_k(n,z)$, respectively. One such sequence is given by $p_k(n,z)$ so that $$p_k(n,z)=z^4-q_{k-1}(n)z^3+(q_k(n)+2)z^2-q_{k-1}(n)z+1$$, where $q_0(n)=1$ and other $q_k(n)^{\prime}s$ are polynomials in n defined by the severely nonlinear recurrence $$4q_{2m-1}(n)=q^2_{2m-2}(n)-(4n+1)\prod_{j=0}^{m-2}\;q^2_{2j}(n),\\4q_{2m}(n)=q^2_{2m-1}(n)-(n-2)(n-6)\prod_{j=0}^{m-2}\;q^2_{2j+1}(n)$$ for $m{\geq}1$, with the usual empty product conventions, i.e., ${\prod}_{j=0}^{-1}\;b_j=1$.

Methods of delivering products to consumers do not act as less important factor than creative activities to create new product designs. Mobilizing various psychological elements based on human instinct and desire, fashion industry presents a product as an object of envy, gaining viewers' attention. Here, the viewer does not simply take the product as an object to view, but also imagine transformation it will bring. The study of the cause and effects of the interaction, which is found in the relationship between "the viewer" and "what is viewed" is an important factor that needs to be identified in the phase of creation as well as in the aspect of delivery. The relationship between the perceiver and what is perceived features in designs, product advertisements, related articles, and fashion shows in modern fashion, serving as a medium that enables the humans, who must inevitably exist between the two poles such as mind and body, the subject and the object, the ego and non-ego, and the reality and an ideal, to communicate between the poles. Humans cannot do arbitrary acts or make arbitrary selections only as they access to foreign things through instinct, desire, or experienced perception, and they are sometimes positioned passive by things. In the background, as there are human dual characteristics in which they are expressed as the ego and another ego who exists inside of the ego, they not only view an object, but also become an object to be viewed. Many products in modern fashion, as the objects of reciprocal transposition, grow giving illusions to humans. Having a desire for such objects is human's instinct and normal act to keep the life balanced between the reality and an ideal, which is based on the activation of reality function. Furthermore, freely acting rather than ignoring or overcoming the desire may be the act of retrieving one's ownership to the ego.
