On page 366 of his lost notebook [15], Ramanujan recorded a cubic continued fraction and several theorems analogous to Rogers-Ramanujan's continued fractions. In this paper, we derive several general formulas for explicit evaluations of Ramanujan's cubic continued fraction, several reciprocity theorems, two formulas connecting V (q) and V ($q^3$) and also establish some explicit evaluations using the values of remarkable product of theta-function.

Animal testing was used traditionally in the cosmetics industry to confirm product safety, but has begun to be banned; alternative methods to replace animal experiments are either in development, or are being validated, worldwide. Research data related to test substances are critical for developing novel alternative tests. Moreover, safety information on cosmetic materials has neither been collected in a database nor shared among researchers. Therefore, it is imperative to build and share a database of safety information on toxicological mechanisms and pathways collected through in vivo, in vitro, and in silico methods. We developed the CAMSEC database (named after the research team; the Consortium of Alternative Methods for Safety Evaluation of Cosmetics) to fulfill this purpose. On the same website, our aim is to provide updates on current alternative research methods in Korea. The database will not be used directly to conduct safety evaluations, but researchers or regulatory individuals can use it to facilitate their work in formulating safety evaluations for cosmetic materials. We hope this database will help establish new alternative research methods to conduct efficient safety evaluations of cosmetic materials.

Decades of psychological research have shown that emotion brings users various kinds of physical and psychological advantages and disadvantages. Moreover, this also impacts human decision-making. However, in spite of the weight of emotion, combined with HCI, relevant research is still insufficient. We hypothesized that the user's temporal emotion could influence the product evaluation, especially in terms of product usability. Two studies were carried out to investigate the effect of induced priming on user evaluations. In exp1, we manipulated participants' temporal emotions using positive and negative images from IAPS. In our results, we saw image priming had a statistically significant effect, with the positive condition group giving the product high ratings for usability. In exp2, emotional image manipulation was conducted with valence and arousal. As a result, we found that the variables of valence and arousal had some interaction effects. These studies have demonstrated that temporally induced emotion could affect users' emotion in different ways, in addition to influencing product evaluations.

The purpose of this study was to examine the effects of brand-related and corporate-realted knowledge on brand-name extension and corporate-name extension, respectively in fashion market. Here, it is designed into three types of brand and corporate awareness; 1) Higher brand awareness and corporate awareness, 2) higher brand awareness and lower corporate awareness, and 3) lower brand awareness and higher corporate awareness. For this study, questionnaires were administered to 700 single women in twenties. The questionnaires were designed to measure evaluations of brand-name extension and corporate-name extension and brand-related and corporate-related knowledge in terms of familiarity, use experience, self-assessed knowledge, evaluation of attributes and attitude. Employing a sample of 621 women, data were analyzed by Multi-Regression analysis. Major findings of this study are summarized as follows; 1) In level of higher brand and corporate awareness, the evaluations of brand-name extension were influenced by corporate-related knowledge such as brand use experience, evaluation of brand attributes and brand attitude. Also, the evaluations of corporate-name extension were influenced by both brand-related knowledge such as brand attitude and corporate-related knowledge such as use experience of product awareness and lower corporate awareness, brand-related knowledge such as evaluation of brand attributes and brand attitude was identified as the important factor in the evaluations of brand-name extension. 3) In level of lower brand awareness and higher corporate awareness, corporate-related knowledge such as attitude toward corporate was identified as the important factor in the evaluations of corporate-name extension.

Consumers have more choices for apparel products as e-shopping grows. This study examines the importance of apparel product attributes and classifies online apparel buyers into groups based on product attribute evaluation in various choice sets. For the empirical research, the online survey was conducted and Latent Gold Choice 4.0 was used for the choice-based conjoint analysis. Five consumer segments are found based on the choice selection of product attributes. The importance of product attributes (online shopping mall, brand, price, and style) and the preference of each product attribute level were different across segments. This research improves the knowledge of the purchasing behavior of online apparel buyers and provides proper attribute combinations of apparel e-shopping for each consumer segment.

Sentiment analysis incorporates natural language processing and artificial intelligence and has evolved as an important research area. Sentiment analysis on product reviews has been used in widespread applications to improve customer retention and business processes. In this paper, we propose a method for performing an intensified sentiment analysis on customer product reviews. The method involves the extraction of two feature sets from each of the given customer product reviews, a set of acoustic features (representing emotions) and a set of lexical features (representing sentiments). These sets are then combined and used in a supervised classifier to predict the sentiments of customers. We use an audio speech dataset prepared from Amazon product reviews and downloaded from the YouTube portal for the purposes of our experimental evaluations.

Today, rapid development and timeliness of introducing a new product be- comes a more influencing factor of determing its competitive power due to a shortened product cycle, while rapid improvement of manufacturing technology makes product design and manufacturing fuse together. This implies that prod- uct usability evaluation and improvement starts right from its design phase, resulting in less development time and cost. To make this possible, proper as- sessment of human reach is one of essential functions for ergonomic product us- ability evaluation, specifically in the platform of computer-aided ergonomic evaluation models or any CAD system with a built-in man model. In this study, an analytic reach prediction algorithm ensuring the posture that human naturally takes, is presented by employing the methods developed for robot kinematics. Among robot kinematic methods for solving the multi-link system, the resolved motion method was found to be effective to solve human reach as a redundant manipulator model. Also, the joint range availability was used as a performance fonction to guarantee human naturalness. The result is expected to be directly applicable to product usability evaluations.

Today's world has been changing form post-industrial society to information society, and criteria of human value, also, has been changing from physical to intellectual and sensible. Based on this trend, intellectual and sensible value of a product is becoming more important in comsumer's market than physical value. The environment of product design has been rapidly changing. Users and consumers pursuit sensible satisfaction through their lives based on images of products. As the environment in which a product is used has been more important, companies have placed more emphasis on consumers and users, and are trying to satisfy their consumers by developing products with emphasis on their design, as well as to develop human technology. In ever-changing environment, a question is if sensible design can be developed in product design. Companies could upgrade their competitive power and brand image only if they could develope designs which could satisfy consumers through sensible design approach with a base on systematic research on h~man sensibility. In this context, the purpose of this study was to: investigate consumer's evaluations on and preferences for formative images of products according to the types of human sensibility. This research study placed emphasis on quantitative analysis of consumers' emotional needs to find out consumer's evaluations on and preferences for formative images of products. The researcher reviewed related literature on human sensibility and design, as well as G-Kansei and product design. Data were collected through a questionnaire and analyzed through a statistical program, and highly effective design strategy was investigated through analysis of data and interpretation of the results.
