        In this paper, we propose a method for diagnosing overload and working load of collaborative robots through performance analysis of machine learning algorithms. To this end, an experiment was conducted to perform pick & place operation while changing the payload weight of a cooperative robot with a payload capacity of 10 kg. In this experiment, motor torque, position, and speed data generated from the robot controller were collected, and as a result of t-test and f-test, different characteristics were found for each weight based on a payload of 10 kg. In addition, to predict overload and working load from the collected data, machine learning algorithms such as Neural Network, Decision Tree, Random Forest, and Gradient Boosting models were used for experiments. As a result of the experiment, the neural network with more than 99.6% of explanatory power showed the best performance in prediction and classification. The practical contribution of the proposed study is that it suggests a method to collect data required for analysis from the robot without attaching additional sensors to the collaborative robot and the usefulness of a machine learning algorithm for diagnosing robot overload and working load.

        This paper investigates the impact of the scarcity information (Lynn, 1991) of a brand in its originating market on the pre- and post-taste evaluations of an imported food brand. We expect a positive effect of scarcity information on food brand evaluations, mainly based on naïve economic theory and the ‘scarce product is good’ heuristic. Four experimental studies confirmed this expectation. Study 1 shows that pre-taste evaluations and price judgment are higher when a new food brand is scarce (vs. when it is not) in its originating foreign market. Study 2 finds that both pre- and post-taste evaluations are higher in the scarce (vs. non-scarce) information condition. Study 3 supports the effect of the scarcity effect (vs. the popularity effect) and supports the mediating role of perceived scarcity. Study 4 replicated study 3 using a different sample and target food. Finally, a single-paper meta-analysis confirmed the strong effect of scarcity information on the evaluation of a food product. This research has several theoretical and practical implications. First, it can extend our understanding of how a nonfood- related characteristic determines food evaluation and preference (Wansink, 2004). Second, we separate the impact of scarcity information from popularity information on food evaluations. Finally, we extend the role of scarcity information to taste evaluation and suggest that the type of information can differentially influence pre- and post-taste evaluations.

        ‘반려동물 가구 1천만 시대’, ‘4가구 중 1가구가 반려동물 가구’. 이제 반려동물과 함께 사는 사람을 보는 것이 흔한 일이 되었다. 반려동물 가구가 전폭적으로 증가하고 있는 추세임에도 불구하고 반려문화의 발전 속도가 현저히 뒤쳐져 위와 같이 반려견의 공공장소 이용에 대한 반려인과 비반려인 간의 갈등이 심화되고 있다. 때문에 반려인과 비반려인간의 갈등을 해소하여야 할 필요성을 느껴 이를 위해 국내 반려견 공공장소 이용에 대한 비반려인의 인식을 조사하고자 하였다. 본 논문은 설문조사를 통해 진행되었으며, 공공장소 중 반려인과 비반려인의 접촉이 가장 빈번한 공원, 인도, 내부 공공장소, 공동주택, 대 중교통을 선정하여 각 장소에 따른 인식을 조사하였다. 설문조사 결과 각 장소마다 비반려인이 반려인과 반려견에 대해 가지고 있는 인식과 요구사항이 다르다는 것을 알 수 있었다. 예상 외로 반려견 자체에 대하여 부정적으로 보는 사람보다 긍정적으로 보는 사람이 다수였다. 반려견의 공공장소 이용을 부정적으로 보는 사람 중에서는 반려견에 대한 인식부족으로 인한 편견을 이유로 드는 한편 반려인의 펫티켓 부족, 반려견 관리 미흡을 이유로 들기도 했다. 이를 개선하기 위해 각 지방자치단체에 동물보호과가 신설 및 증설을 통해 처벌뿐만 아니라 목줄 미착용과 같은 동물보호법 위법행위에 대한 감시 감독 또한 강화해야 한다. 더불어 국가적 차원에서 국민을 대상으로 인간과 동물의 공존을 위한 교육이 시행되어야 한다. 동시에 반려인을 대상으로 한 올바른 펫티켓을 비롯한 반려동물 관리에 대한 교육이 필요하다.

        최근 한국 사회는 반려견을 키우는 인구가 빠르게 증가하고 있다. 한국 사회의 주거환경 특성상 소형 견종을 반려하는 가정이 많은데, 시츄, 말티즈, 푸들 등이 이에 해당한다. 이들 견종은 흐르는 눈물 과다로 인한 문제를 겪는 대표적인 견종이다. 이를 개선하기 위하여 현재 시중에는 이미 다양한 제품이 나와 있으나 그중 몇 가지 제품에서 타일로신이 발견되어 논란이 되었다. 타일로신은 설사 위장장애 등의 부작용을 야기하여 수의사의 처방이 필요한 항생제이다. 이 때문에 한약재(Compound A, Compound B)을 활용하여 부작용이 없는 안전한 보조제를 개발하고자 한다. 실험에 참여하는 반려견의 몸무게에 비례하여 2주간 보조제를 복용하고 눈물검사키트를 사용하여 전과 후를 비교하고 육안으로 확인되는 변화를 관찰한다. 실험 결과 전체적으로 흐르는 눈물의 양이 감소하였고, 부가적으로 발견한 효과로 눈물양이 부족하거나 과다한 반려견의 눈물양이 정상화된 것을 발견할 수 있었다.

        Past research has shown that the self-congruity effect (Sirgy, 1982) is an important key predictor for consumers’ responses (e.g., attitude, purchase intention, choice, satisfaction, and loyalty) toward various marketing stimuli such as brand, store, and product (Barone, Shimp, and Sprott, 1999; Sirgy, Grewal, & Mangleburg, 2000). The self-congruity effect refers to the match between consumers’ actual self-concept and the image of objects compared, such as brand image, product image, store image, and advertising materials (Choi & Rifon, 2012; Sirgy, Grewal, & Mangleburg, 2000). These relationships, however, have not been tested in the context of luxury brand products (Sirgy, 1982). Our purpose is to address this knowledge gap by investigating the relevancy of self-congruity theory to the purchase of luxury brands. In contrast to the long-standing self-congruity effect, we propose that actual self-incongruity and ideal self-congruity effects will work when consumers evaluate luxury fashion brands. A survey method was used to gather data. Data were collected through an online panel provided by E-rewards, a marketing research company located in the United States. A stratified sampling method was employed to obtain an evenly distributed number of participants from different income classes. The strata was identified by income. Three strata were developed: (1) more than $100,000; (2) $55,000 to less than $100,000; and (3) less than $55,000. The sample (n = 502, average age = 41) represented most demographic categories. We tested the influence of actual self-incongruity and ideal self-congruity on brand attitude, purchase intention, and perceived quality for 3 brands. Actual self-incongruity had a significant positive effect on brand attitude, whereas ideal self-congruity had a significant positive effect on brand attitude, purchase intention, perceived quality. Overall, the results supported our main hypothesis. We conducted an additional analysis to examine the moderating role of income. Specifically, for brand attitude, the influence of actual self-incongruity was significantly positive only for the low-income group. The influence of ideal self-congruity was significantly positive only for the low- and middle-income groups. For purchase intention, the influence of ideal self-incongruity was significantly negative only for the low-income group, whereas the influence of ideal self-congruity was not significant for the middle- or high-income groups. Finally, for perceived quality, the influence of actual self- and ideal self-incongruity was significant only for the middle-income group, whereas that influence was not significant for the high-income group. This research contributes to the self-congruity effect in the context of luxury brands. Our results show the positive influence of ideal self-congruity and actual self-incongruity on the evaluation of luxury brand products. This is the first study identifying that actual self-congruity has a negative influence on the evaluation of brands in a luxury market context, as opposed to previous findings. Our results provide important implications to practitioners in planning their marketing communication strategies or consumer relationship management for luxury brand consumers.

        To decide on the designation of a tidal-flat Provincial Park, a study area was defined in line with domestic and international case studies of Provincial Parks. A survey on landscape, geology, biota, and cultural resources was conducted in four tidal-flat areas including Bigeum-myeon and Docho-myeon, which are part of the UNESCO Biosphere Reserve in Shinan, Jeollanam-do. To identify areas most suitable to be designated as Provincial Park, a PSR evaluation process was adopted. This has resulted in the selection of the ‘Palgupo’ area surrounding Bigeum, Docho, Haui, Shinui, Jaeun, Amtae, Palgeum, Anjwa and Jangsan. Also the tidal-flat areas at Aphae-myeon, which are ecologically linked with the Jeungdo Tidal-flat Provincial Park, were included. The selected areas resulting from this study will meet various characteristics of tidal-flat ecosystems including naturalness, ecological network, rarity and eco-cultural diversity. After the tidal-flat Provincial Park has been specified, there is a need to perform a long-term sustainable management plan.

        This study was undertaken to determine how different harvesting times affected the nutritional compositions in two forage rice varieties(Nokyangbyeo, Dasanbyeo). The contents of crude protein in leaf and stem decreased, with time, after heading in Nokyangbyeo, Dasanbyeo, but there was not so changed in that of spikes. Contents of Neutral Detergent Fiber(NDF) and Acid Detergent Fiber(ADF) in leaf and stem increased slightly but decreased rapidly in these of spikes. Contents of Total Digestive Nutrient(TDN) in spikes was the highest compared to that of the other parts of plants. Contents of Total Digestive Nutrient(TDN) in plants was the highest at 40 days after heading in Nokyangbyeo and was the highest at 50 days after heading in Dasanbyeo.

        The growth period of corn is so shorter than that of any other crops. So, corn is the most promising crop in upland cropping systems. However, there was not so much in basic informations related to cultivation method including seeding period. This study was undertaken to investigate how different seeding date affected the growth characteristics and yield in corn. Two corn varieties(Chalok 4, Ilmichal) were planted on 6 different seeding date(from April 11 to July 10) in upland and paddy field. The total growth period was the longest(105 days) on the seeding date of April 11 regardless of testing varieties and cultivation condition. The total growth period was ranged from 77 days to 86 days in other seeding dates. The commercial yield of corn was higher in paddy field than that of upland field. In consideration of economic productivity, it was concluded that seeding date can be possible from early in April to middle of July in middle and south plain regions.

        This study was undertaken to determine how different seeding methods and harvesting times affected the biomass partitioning of forage rice. Two rice varieties(Nokyangbyeo, Dasanbyeo) were planted by 4 different seeding method(rice transplanting, direct seeding on dry paddy, water hill seeding, water seeding). The heading date was delayed more than 10 days in water seeding and water hill seeding compared to that of rice transplanting method. The biomass production by harvesting times was the highest at 50 days after heading in two rice varieties and was high in order of direct seeding on dry paddy〉water hill seeding〉rice transplanting〉water seeding in seeding methods. The ratios of spikes dry weight to total dry weight increased, with time, after heading. But the ratio of leaf and stem dry weight to total dry weight decreased, with time, after heading.
