Purpose: This study explored factors affecting the purchase of fair trade hand-made products. We focused on the difference between the mediating effect of purchase intention and purchase purpose, and verified the additional effectiveness of premium prices. Research design, data and methodology: The data was collected through an online survey. The reliability and validity of each variable used in the questionnaire were verified. Then, each hypothesis was analyzed through multiple regression analysis. Results: First, individual social responsibility and purchasing experience of general fair trade products have a definitive effect on the intention of purchasing fair trade hand-made products. Second, the willingness to pay premium prices varies depending on whether it is an individual's consumption or consumption for others. Third, the higher the individual's social responsibility and experience in purchasing fair trade products, the more willing he is to pay premium prices. Fourth, the purchase intention of fair trade hand-made products is to have the effect of partial mediation. Fifth, when choosing a gift for an adult, it was determined that the consumer was willing to pay premium prices the highest amount. Conclusions: In terms of factors affecting the purchase of fair trade hand-made products at premium prices, it was confirmed that individuals' social responsibilities and purchases of fair trade general products had an impact.

International book fairs are business enterprise to promote and facilitate international trade of copyright. National reading improvement policies, on the other hand, are supposed to be made to maximize the role of national and regional libraries, not just to boost publication industry. However, Korean government authorities of the reading improvement policies and the Organizing Committee of the Seoul International Book Fair have mapped out and, in effect, carried out their plans as if reading improvement policies are closely related to hosting international book fairs. It is important to realize that hosting book fair has pecuniary motives while making policies for reading improvement must be feared toward the betterment of the general public by reading. In this respect, this study has attempted to point out the problems of the Seoul International Book Fair that are regarded as to relate to reading improvement.

Along with the development of Information Technology, online transactions through Internet have become more popular for the reasons of convenience and efficiency. In order to provide secure and reliable online transactions, an effective electronic payment protocol is crucial. In this paper, we propose a novel electronic payment protocol for digital product transactions with an offline arbiter to achieve fair exchange, automated dispute resolution, customer anonymity, and customer unlinkability. In our protocol a product token is adopted to eliminate the need of key management for digital product decryption in the offline arbiter. In addition, Elliptic Curve Cryptography (ECC)-based self-certified public key is utilized to further reduce computing overheads. According to our analysis, the efficiency of our protocol can be greatly increased in comparison with previous literatures.

We investigated the safety and efficacy of pemetrexed monotherapy in patients with lung adenocarcinoma and various renal conditions, including chronic kidney disease. We also analyzed whether baseline renal function affected progression-free survival (PFS). We retrospectively analyzed 71 patients who received maintenance-and second-line pemetrexed monotherapy. Patients were divided into two groups according to estimated glomerular filtration rate (eGFR): fair eGFR (>60 mL/min/1.73 m²) and lower eGFR (59 mL/min/1.73 m² or less). The safety and efficacy were evaluated for each group. Median ages were 73.2 years in the lower eGFR group (n=28) and 64.5 years in the fair eGFR group (n=43). Patients with a lower eGFR achieved a median PFS of 4.7 months, while the median PFS for patients with a fair eGFR was 2.7 months. The difference between the two groups was not statistically significant (P=0.075). Both groups showed treatment-related low-grade hematological and non-hematological adverse events. Pemetrexed monotherapy is safe and effective in patients with lung adenocarcinoma with a lower eGFR.

The purpose of this study is to analyze the field of Earth science at a science fair. For this purpose, 566 pieces of data spanning 21 years (2000 to 2020), acquired from entries in the Earth Science section on the science fair website, were analyzed using the semantic network method. As a result, geoscience topics have been actively explored in works submitted for the Earth Science section of the science fair. Fossils from the Cretaceous period of the Mesozoic Era were particularly predominant. Together with these, keywords corresponding to astronomy, space science, and atmospheric science formed a small-scale network. Astronomy and space science mainly dealt with the dynamic characteristics of asteroids, Venus, and Jupiter. Other subjects included the solar system, sunspots, and lunar phases. Atmospheric science has focused on atmospheric physics, atmospheric observation and analysis technology, atmospheric dynamics, air quality monitoring, while marine science has been limited to physical oceanography and geologic oceanography. This study, is expected to help select Earth Science topics and conduct inquiry activities in schools.

In this study, the notion of payment intention price was introduced and examined in relation with self-image congruence, clothing preference and two types of reference price: expected price and fair price. One hundred samples of female collegiate students participated in the group survey and responded to the instrument including variables of clothing image evaluation, clothing preference, reference price, payment intention price toward a one-piece dress as the stimulus, and ideal self-image perception. Descriptive statistics, correlations, and regressions were applied on data analysis. The results were as follow. Payment intention price was determined by clothing preference and fair price, and the explaining power of fair price was greater than clothing preference. One confirmatory path was observed that self-image congruence effects clothing preference, and then clothing preference effects payment intention price. The other confirmatory path was from expected price to fair price and fair price to payment intention price.

The purpose of this study was to explore the consumer responses such as willingness to pay premium and purchasing cost for fair trade coffee as an ethical product while considering the treatment effect of consumer knowledge. First, the levels of consumer knowledge, willingness to pay premium and purchasing cost were presented. Then, the influencing factors on willingness to pay premium and purchasing cost of fair trade coffee were analyzed by applying the treatment effect model. From the results, first, the level of willingness to pay premium was high and consumers having purchasing experience of fair trade coffee spent 9,923 won at once, while less than half of the consumers knew the fair trade coffee. Second, consumer knowledge, ethical judgement, perception of price value, education level and pocket money significantly influenced to willingness to pay premium, while consumer knowledge, information evaluation, importance of fair trade criteria and level of education significantly influenced to purchasing cost for fair trade coffee. Especially, consumer knowledge of fair trade coffee was an important influencing factor for willingness to pay premium and purchasing cost indirectly as well as directly. Thus, this study might provide some useful information for consumers to choose the ethical behavior and the related companies to create effective promoting strategies for ethical products.

The purpose of this study is to understand the elementary student's growth and its implications from the students' experience participating in the science fair by phenomenological study. The results are as follows. First, the students have various experiences. They acquire scientific knowledge and inquiry skills by conducting in-depth experiments, visiting several places, and interviewing experts. They have some experience in writing experiment journals to record the inquiry process in their own language, and presenting their results in public. Second, the students suffer several difficulties while preparing for the science fair. They have some difficulties when the results were not consistent with the hypothesis, or they had to repeat the experiment over and over. They feel burdened in writing the experiment journal. They had a few time to meet friends or for hobbies. Third, the students improve scientific attitude through the science fair, and they receive a positive effect on the affective side. They developed scientific interest, curiosity, cooperation, etc. And they also gained a sense of accomplishment, confidence, friendship, good relationship with teachers, career interest, etc. This study finds out that students participating in the science fair have a lot of experience that cannot be done easily in a normal science class. Even though students confront some difficulties in the inquiry process, they make good progression and feel accomplished. So the science fair is valuable experience for them.

In this paper we propose a fair and secure e-commerce model for P2P network, in which communication entities can buy and sell products by P2P contract. In particular, we focus on a fair transaction protocol that is based on a collaboration with distributed communication entities. This feature makes our model very attractive in P2P networking environment which does not depend on any central trusted authority for managing communication entities.

In this paper, we use the ECMA-392 standard, the first cognitive radio networks to meet the demand for IT services in the ship. First, we learn about ECMA-392-based network and examine the consideration and the problems for assigning channels to the device. And, we propose a fair channel resource allocation to ensure efficiently channel required by device groups in ECMA-392 MAC protocol. This is a method to reallocate the channels fairly with considering the channel assignment parameters to a new device group and existing device groups. The simulation results show that the proposed scheme improves throughputs compared to the existing one.
