In this paper, we exhibit the equivalence between different notions of unique range sets, namely, unique range sets, weighted unique range sets and weak-weighted unique range sets under certain conditions. Also, we present some uniqueness theorems which show how two meromorphic functions are uniquely determined by their two finite shared sets. Moreover, in the last section, we make some observations that help us to construct other new classes of unique range sets.

With increasing interest in sustainability, several fashion and beauty brands have developed and offered unique types of sustainable packaging in their stores (e.g., 'knot-wrap,' 'seaweed-based' packaging). The purpose of this study was to investigate the perceived value (i.e., green, aesthetic, functional, emotional, social, self-expression) of unique types of sustainable packaging and its impact on consumers' packaging evaluation, store evaluation, and store patronage intentions in the context of a fashion retail store. This study also assessed the moderating effects of consumer innovativeness and environmental concern. Data were collected from 210 US consumers aged 18 to 26 years through Amazon MTurk. The results of structural equation modeling revealed that green, emotional, self-expression, functional, and aesthetic values perceived from unique types of sustainable packaging had significant positive impacts on packaging evaluation. Packaging evaluation, in turn, positively impacted store evaluation, subsequently influencing store patronage intentions. Consumer innovativeness and environmental concern moderated several paths between the variables. This study adds to the existing literature on sustainable packaging by investigating consumer responses to sustainable packaging that incorporates the 'uniqueness' aspect. Managerial implications regarding the importance of developing and offering unique types of sustainable packaging for fashion brands in their retail stores are discussed.

In this paper, a model for an inventory whose stock decreases with time is considered. When a deliveryman arrives, if the level of the inventory exceeds a threshold $\alpha$, no stock is delivered, otherwise a delivery is made. It is assumed that the size of a delivery is a random variable Y which is exponentially distributed. After assigning various costs to the model, we calculate the long-run average cost and show that there exist unique value of arrival rate of deliveryman $\alpha$, unique value of threshold $\alpha$ and unique value of average delivery m which minimize the long-run average cost.

Due to the potential growing capability that reflects future value, the market value of internet business companies (IB) are still evaluated high although major players like Amazon continuously suffer losses. Then, how do investors valuate the potential growing capabilities given that traditional financial/accounting based valuation approaches seem to be inappropriate for IB. This study attempts to provide an answer to this issue. We, therefore, analyzed the predictability of various accounting and non-accounting variables for IB value. These include book value, net income, unique visitors, page view, reach rate, public float and institutional holdings. Because of being in infant stage and difficulties in obtaining necessary web traffic data, sample of 20 pure IB were selected from Korea Stock Exchange Market, KOSDAQ, and informal market. The results of this study showed that web traffic date had the strongest relationship with IB value. In particular, unique visitors and reach rate were found to be best predictors for IB value while page view was reasonable indicator. Interestingly, net income was not found to related to IB value. This calls for an attention to the typical characteristics of IB that my hinder the usage of traditional valuation approaches for IB. Another results revealed that none of both public float and institutional holdings was significantly associated with IB value, indicating market’s supply-demand factors were less important than traffic information.

The unique colors of paper, that is, blue, green, red, and yellow were used in the estimation of color from the subjective feeling. The monochrome with unique color or the unique color surrounded with the background color was presented. subject gazed the monochrome or the unique color, which was tailed target rotor. The target and background color were the complementary color each other. The various ratios of the area of gazed color and background were taken. Subject answered the level of subjective feeling consisted of pair of adjective items for unique color presented. With the use of the subjective feeling for the target color presented, the estimation of the unique color was cai\ulcornerlied out due to Fuzzy theory and neural networks. The results of color difference between unique color presented and the estimated color gave very small value for the case without background, while the results of the case with background color depended on the ratio of area of presented color and background color till the ration of 2:1, The relation showed the Kirschman's law, The color difference saturated In the increase of area of background with the ratio more than 2:1.

The unique colors of paper, that is, blue, green, red, and yellow were used in the estimation of color from the subjective feeling. The monochrome with unique color or the unique color surrounded with the background color was presented. Subject gazed the monochrome or the unique color, which was called target color. The target and background color were the complementary color each other. The various ratios of the area of gazed color and background were taken. Subject answered the level of subjective feeling consisted of pair of adjective items for unique color presented. With the use of the subjective feeling fer the target color presented, the estimation of the unique color was carried out due to Fuzzy theory and neural networks. The results of color difference between unique color presented and the estimated color gave very small value for the case without background, while the results of the case with background color depended on the ratio of area of presented color and background color till the ration of 2:1, The relation showed the Kirschman's law. The color difference saturated in the increase of area of background with the ratio more than 2:1.

A theoretical investigation to find thermodynamically optimum design conditions of conduction-cooled Peltier current leads is performed. A Peltier current lead (PCL) is composed of a thermoelectric element (TE), a metallic lead and a high temperature superconductor (HTS) lead in the order of decreasing temperature. Mathematical expressions for the minimum heat flow per unit current crossing the TE-metal interface and the minimum heat flow per unit current from the metal lead to the joint of the metal and the HTS leads are obtained. It is shown that the temperature at the TE -metal interface possesses a unique optimal value that minimizes the heat flow to the joint and that this optimal value depends on the material properties of the TE and the metallic lead but not the joint temperature nor electric current. It is also shown that there exists a unique optimal value for the joint temperature between the metal and the HTS leads that minimizes the sum of the power dissipated by ohmic heating in the current leads and the refrigerator power consumed to cool the lead, for a given length of the HTS.

Among the diverse apartment brand TV Ads, KCC Switzen uses a unique advertising strategy. Unlike their competitors, KCC Switzen uses a strategy without fancy rhetoric such as luxury, premium or high-tech to enhance the value of their housing. In order to define the value of contemporary housing this paper analyses the socio-cultural messaging of KCC Switzen's television advertisements using Qualitative content analysis and Floch's Semiotic Square of Consumption Values method. As a result of this analysis, KCC Switzen's advertisements are shown to contain both intrinsic values of housing and cultural humanism by asking ablout the daily lives of real families and their relationships with neighbors. This directly contrasts with the standard advertisements that focus on the investment value of residential housing. The unique KCC Switzen advertising strategies are expected to change the paradigm of residential housing.

Contemporary Chinese "micro-perspective" painting is an artistic phenomenon that we cannot ignore. It is the young artists who focus on themselves and their communities, record their stories and emotions in their life fragments into the coming history, and diary paintings as "micro-perspective" paintings allow "marginal people" to find their place. Based on the analysis of the aesthetic form and aesthetic characteristics of Chinese contemporary art, this paper explores the three aesthetic dimensions and their inherent aesthetic value, and explains its significance from the perspective of "micro-view" aesthetics. In the contemporary context, "micro-perspective" painting has become a unique cultural phenomenon, a consciousness situation. However, this phenomenon has a very unique artistic value and cultural value for the youth art group and even the formation of aesthetic culture and zeitgeist in China's current society.
