In this study, we examined the motivations of using Kakaotalk's gift that is one of services provided by Kakaotalk, the most popular mobile-based messenger. We also investigated possible effects of these motivations on the satisfaction of the Kakaotalk's service and a potential association of these motivations with the frequency of purchasing gifts using the service. In order to answer the research questions, we conducted a survey that recruited 220 users ranging from teenagers to in forties. As the main results of analysis, we identified four different types of user's motivations for Kakaotalk's gift: beneficial motivation, convenient motivation, improvised buying motivation, and entertaining motivation. Both the beneficial motivation and the entertaining motivation were significantly associated with the gratification of using Kakaotalk's gift, which was in turn significantly associated with the frequency of purchasing gifts through the service.

Since a smart phone has been popular, 91% of the internet users are utilizing the technology in all places for chatting and messenger which overtake share of voice and visual call utilization. The phenomenon is remarkable to young generations between teenager and thirties, which leads to mobile messenger shopping such as mobile digital voucher and coupon buy. In this research, we clarify whether traditional gift-giving motivations works on digital coupon gift-giving, and two technology acceptance model factors: perceived usefulness and ease of use affects between motivations and intention to gift-giving. The result shows three traditional gift-giving motivations: experiential, obligated and practical attitude affects intention to digital mobile coupon gift-giving and ease of use of the digital mobile coupon works parameter of the relation rather than usefulness. In other words, gift-giving purpose digital coupon users give a gift with traditional gift-giving motivation but has the stronger intetnion to gift-giving by technology ease of use.

Consumers purchase gifts for themselves and for others. This research examined whether one's preferred purchase type (material or experiential) would depend on the gift recipient (self or others). A total of 200 participants took part in online studies via Amazon Mechanical-Turk. Based on the construal-level theory, people will focus on concrete product attributes for psychologically close objects; however, for psychologically distant objects, people will concentrate on abstract product attributes. Study 1 demonstrated that participants preferred material over experiential purchases in self-gifting situations, while they preferred experiential compared to material gifts for others. In Study 2, it was found that individual differences in emotional disconnection moderated the effect of gift recipient on preferred gift type. Specifically, the differences in preferred gift type increased as one's emotional disconnection level increased. The results of this research have theoretical implications in terms of extending construal-level theory to gift-purchasing behaviors. Furthermore, this research has practical implications for marketers and advertisers. Limitations and possible future research directions were also discussed.

The purpose of this article is to show profit margin hedging can be an optimal strategy in crude oil purchasing. This study theoretically analyzes profit margin hedging strategy is optimal in crude oil purchasing using expected target utility function and conducts simulations to show if the profit margin hedging is profitable. In addition, this study tests existence of mean reversion of crude oil futures prices to confirm the theory that profit margin hedging is more profitable than other strategies, such as always hedging or buying at expiration with spot price, if futures prices are mean reverting. The simulation results show that the expected utility of profit margin hedging higher than other strategies. Although we cannot find any evidence that crude oil futures prices follow mean reverting process, we can conclude that profit margin hedging can be optimal strategy in crude oil purchasing based on theoretical proof and simulation results.

The purpose of this study is to examine the relationship between gender, gift recipient, and group identity by product category of Korean consumers. 672 usable questionnaires from South Korea completed a self- administered survey with a five-point Likert scale. This questionnaire evaluated the perceived importance of group identity when buying apparel and electronics as a gift for kin, nonkin, and co-workers. The interaction between gender, gift recipient, and group identity were statistically significant. The results suggest that the importance of group identity may vary when gender and gift recipient differ by product category. Recommendations for future research are discussed.

본 연구는 두 가지 선물상황(생일, 크리스마스)과 선물수용자(가족, 친구)에서 성별에 따라 선물 속성지각에 차이가 있는지를 밝히고자 하였다. 질문지를 이용하여 미국 남녀 비자 97명을 대상으로 자료수집 하였으며, 자료분석을 위해 MANOVA(Multivariate Analysis of Variable)를 실행하였다. 분석결과, 가족과 친구를 위한 생일선물상황에서 성에 따라 쾌락적 속성(독특한, 유행하는, 재미있는)의 중요성 지각에 차이를 보여 여성이 남성보다 선물의 쾌락적 속성을 더 중요하게 지각하였다. 또한 가족과 친구를 위한 크리스마스 선물상황에서도 성별에 따라 쾌락적 속성에 차이를 보여 여성이 남성보다 가족을 위한 선물로써 독특한, 유행하는 속성을 더 중요하게 지각하고, 친구를 위한 선물은 독특한, 재미있는 속성이 더 중요하게 지각되었다. 그러나 실용적 속성(내구성있는, 실용적인, 비싸지 않은)에서는 두 가지 상황의 가족과 친구를 위한 선물지각에 대해 성별에 따라 유의한 차이를 보이지 않았다. 따라서 본 연구결과. 소비자들은 선물구매상황에서 일반제품과 달리 쾌락적 가치를 더욱 중요하게 인식하고 있으며, 성별에 따라 선물 상황과 수용자에 대한 선물의 쾌락적 속성지각에 차이를 나타냄으로써 성별에 따른 차별화된 선물상품개발 및 이미지 포지셔닝 전략을 통해 효과적 마케팅 관리가 이루어져야 할 것이다.

As the production of new and renewable energy such as solar and wind power has diversified, microgrid systems that can simultaneously produce and consume have been introduced. In general, a decrease in electricity prices through solar power is expected in summer, so producer protection is required. In this paper, we propose a transparent and safe gift power transaction system between users using blockchain in a microgrid environment. A futures is simply a contract in which the buyer is obligated to buy electricity or the seller is obliged to sell electricity at a fixed price and a predetermined futures price. This system proposes a futures trading algorithm that searches for futures prices and concludes power transactions with automated operations without user intervention by using a smart contract, a reliable executable code within the blockchain network. If a power producer thinks that the price during the peak production period is likely to decrease during production planning, it sells futures first in the futures market and buys back futures during the peak production period to make a profit in the spot market. losses can be compensated. In addition, if there is a risk that the price of electricity will rise when a sales contract is concluded, a broker can compensate for a loss in the spot market by first buying futures in the futures market and liquidating futures when the sales contract is fulfilled.

In addition, if there is a risk that the price of electricity will rise when a sales contract is concluded, a broker can compensate for a loss in the spot market by first buying futures in the futures market and liquidating futures when the sales contract is fulfilled.

This study aims to suggest basic data for developing forest product in Jeongeup City by surveying and analyzing consumer awareness and purchasing behavior. A survey was conducted focusing on local tourist attractions in Jeongeup City, and the analysis was conducted on 234 people. Among the local specialty processed products that the survey participants had experience in purchasing, food was mainly tea, concentrate solution, liquor, snacks and fruit syrup/enzyme. The therapy was shown in order of soap, aroma oil, and lotion. It was found that the purchase cost was more than 10,000 won and less than 30,000 won. Major purchase uses were for direct use and gifts, and 56.8% of the customers were satisfied with the satisfaction of the products, which were found to be purchased because of their good quality, good gift, and good health functions. In the question of 11 kinds of forest products, the subjects were aware of bokbunja, balloon flower, wild flower, deodeok, bracken, durum, and mal, among which bokbunja and wild flower were recognized as the representative forest products of Jeongeup. A cluster of food and therapy product selection attributes was analyzed to find target consumers. As the group that is interested in forest products and values the safety and quality of products is highly recognized, the value of forest products should be increased in consideration of the quality and safety of forest products when developing products in the future.

본 연구의 목적은 해외여행 동기에 따라 여행자들의 집단을 나누고 각 집단별로 해외여행시 구매하는 상품이나 이용 매장의 특성을 비교하는데 있다. 문헌연구를 통해 여행동기와 구매상품의 종류와 속성, 쇼핑장소의 유형과 속성에 대한 주요 문항들을 추출하였다. 20-50대 해외여행 경험자 431명을 대상으로 설문조사를 실시하였고 K-평균 군집분석을 통해, 적극적 집단, 소극적 집단, 자연 쾌락추구 집단, 가족 발견추구 집단의 4개의 군집이 확인되었다. 적극적인 여행자들은 해외에서 구매하는 모든 상품종류에 대해 가장 높은 관심을 보였으며 다른 세 집단보다 유의하게 차이가 있었다. 특히 소극적인 여행자나 자연 쾌락추구 여행자들보다 패션 사치품이나 기념품 구매를 중요하게 생각하는 것으로 나타났다. 또한 상품 속성에서 디자인과 명성, 실용성, 가격과 품질 등의 요인들을 중요하게 고려하였다. 구매 장소 측면에서는 적극적 집단은 지역 시장, 패션매장, 선물매장 순으로 선호하였으며 소극적인 여행자들은 패션매장을 더 선호하는 것으로 나타났다. 구매장소 속성의 중요도는 편의성, 디스플레이, 매장위치 및 판촉활동 순으로 중요시되었으며 적극적인 여행자들은 다른 세 집단 여행자들보다 매장 편의성에 대한 관심이 유의하게 높았다. 가족 발견중심 여행자와 자연 쾌락추구 여행자 집단은 쇼핑행동이 비슷하거나 일부 요인에서만 차이가 있었다. 소극적 여행자들은 나머지 세 집단과 구별되게 모든 쇼핑행동에 대한 관심이 낮았다. 여행동기에 근거한 시장세분화는 서로 다른 쇼핑행동을 예측할 수 있는 변별력이 있음을 보여주었다.
