빠르게 변화하는 해외 시장 환경 및 소비자 니즈의 변화에 발맞춰, 기업의 혁신 전략의 중요성이 강조되고 있음에도 불구하고, 경쟁전략과 신제품개발속의 관계에 관한 연구가 많이 이루어지지 않 은 실정이다. 특히, 대기업에 비해 유무형 자원의 부족에 한계를 가지고 있는 중소기업에게 있어, 해외 시장 환경의 변화에 대처하는 경쟁전략의 선택은 중요한 의사결정 요소이며, 이러한 경쟁전략 은 신제품개발속도에 영향을 미치는 주요한 전략적 요인으로 작용한다. 이에 본 연구는, 차별화전 략과 비용우위전략이 신제품개발속도에 미치는 영향을 알아보고, 시장역동성이 이러한 관계에 어 떠한 조절효과를 미치는지 살펴보고자 한다. 이를 위해 한국 중소수출업체를 대상으로 설문을 진행 하였으며, 차별화전략과 비용우위전략이 신제품개발속도에 긍정적인 영향을 미치는 것을 확인하였 다. 나아가, 시장역동성이 높을수록, 차별화전략이 신제품개발속도에 미치는 긍정적인 영향은 커지 지만, 비용우위전략이 신제품개발속도에 미치는 긍정적인 영향은 약해지는 것을 확인하였다. 본 연 구는, 경쟁전략이 신제품개발속도에 미치는 영향을 제안하고 검증하였으며, 시장이 빠르게 변화할 경우, 경쟁전략의 긍정적인 효과가 달라질 수 있음을 확인하였다는 점에서 학문적 및 실무적 시사 점이 있을 것으로 기대된다.

이 글은 남한 동해안에 유입된 북한 생활쓰레기로부터 시작된다. 그동안 북한 쓰레기가 남한에 유입된다는 사실은 해양쓰레기 실태조사 관련 연구 에서 주로 이루어졌다. 환동해권 해양쓰레기 유입 등에 관한 연구에서도 주로 한국과 일본, 극동러시아 등의 유입 현황에 관한 연구는 있지만, 북 한은 논의의 대상에서 제외되었다. 본 연구는 기존의 해양학 관점이 아닌 북한학 관점에서 남한 해안에 유입된 북한 쓰레기 문제를 다루었다. 북한 생활쓰레기 중 상품포장지는 직접적으로 북한 상품 생산 현황과 브랜드 등을 알 수 있으며, 간접적으로는 북한 내 경제 상황과 상품 유통 지역망 등을 알 수 있기 때문이다. 동해안 지역에서 수거한 북한제품 포장지를 살 펴보면 대부분 생산공장은 평양으로 표기되었다. 이를 통해 평양에서 생산 한 제품이 동해안 지역으로 유통됨을 알 수 있다. 또한 동해안 지역은 북 한을 대표하는 대도시인 원산, 청진, 함흥, 라선 등이 있는데, 실제로 상품 포장지에는 이 지역 생산공장이 표기되는 사례도 있었다. 김정은 집권 이 후 매년 국가적 차원에서 국가디자인전시회를 개최할 만큼 산업미술을 강 조하는데, 특히 상품의 고유한 특징을 표현하는 상표도안을 강조한다. 본 연구에서는 동해안 주요 도시에서 생산한 제품을 중심으로 같은 품목이지 만 공장별로 어떻게 상표도안이 다른지 살펴봤다. 북한 쓰레기에 대한 북 한학적 시각과 해양학적 시각의 학제간 연구를 통해 남한에 유입되는 북 한 생활쓰레기에 대한 연구의 폭을 넓혀갈 필요가 있다.

본 연구는 코로나 19로 인해 불안, 우울 등의 심리적 어려움을 겪는 사람들이 많아지면서 사회 구성원 간의 갈등을 해결하려는 방안의 하나 로 ‘관광’을 치유의 수단으로 활용하여 ‘치유관광상품’을 개발하는 것을 목적으로 한다. 그 결과, 첫째, 규칙적인 둘레길 산책 프로그램이나 도보 여행 관련 상품 개발, 둘째, 스트레스 해소를 위한 야외 관광 활동 관련 상품 개발, 셋째, 친구, 친지, 가족과 동행하는 관광상품 개발, 넷째, 하 던 일과 생각을 잠시 멈추는 등의 넋 놓기 관광상품 개발 등을 제시하였 다. 이는 코로나 19 장기화에 따른 우울증 ‘코로나 블루(Corona Blue)’ 가 일상생활의 어려움을 넘어 분노까지 느끼는 ‘코로나 레드(Corona Red)’를 호소하는 사람이 많아지면서 위험사회가 되어가고 있다는 관점 에서 이를 극복하기 위한 정책 대응방안을 요구받는 시점에서 제시한 것 이다. 본 연구는 전 국민적 심리 상담이 필요한 시점에서 관광을 기반으 로 치유하는 ‘치유관광상품’ 개발이 갈수록 위험사회로 치닫고 있는 우리 사회의 문제점을 조금이나마 해결할 수 있기를 바란다.

To determine the acceptability of Grain Utilization Value Added (GUVA) Japonica rice variety developed by the International Rice Research Institute (IRRI) and South Korea’s Rural Development Authority (RDA), home use tests were conducted in n=69 businesses that were using Japonica rice. In general, they were satisfied with the Japonica brands, because they provided them with the particulars needed in their Japanese and Korean dishes. According to them, the value and quality of the Japonica rice justify the price. However, the GUVA Japonica Rice variety’s positive ratings were significantly lower compared to the brands they were used to. This applied to both their overall and attributespecific evaluations. Among the attributes, size, shape, aroma, and stickiness received significantly lower ratings compared to the other Japonica varieties. For them, it was too small, too round, less aromatic, and less sticky which may lead to challenges in preparation consequently affecting the commercial acceptability of the dishes they offer. Even with this experience and perception, they were still willing to consider the GUVA Japonica Rice when it was available in the market. Using the Van Westendorp pricing model, GUVA Japonica yielded a price of PHP 51.00 (1.01 USD) which was competitive. These findings provide recommendations for measures that should be put in place so that value chain players can preserve and maintain quality until the rice reach the business market.

In this study, text mining was conducted on the product names of skirts, pants, shirts/ blouses, and dresses to analyze the characteristics of keywords appearing in online shopping product names. As a result of frequency analysis, the number of keywords that appeared 0.5% or more for each item was around 30, and the number of keywords that appeared 0.1% or more was around 150. The cumulative distribution rate of 150 terms was around 80%. Accordingly, information on 150 key terms was analyzed, from which item, clothing composition, and material information were the found to be the most important types of information (ranking in the top five of all items). In addition, fit and style information for skirts and pants and length information for skirts and dresses were also considered important information. Keywords representing clothing composition information were: banding, high waist, and split for skirts and pants; and V-neck, tie, long sleeves, and puff for shirts/blouses and dresses. It was possible to identify the current design characteristics preferred by consumers from this information. However, there were also problems with terminology that hindered the connection between sellers and consumers. The most common problems were the use of various terms with the same meaning and irregular use of Korean and English terms. However, as a result of using co-appearance frequency analysis, it can be interpreted that there is little intention for product exposure, so it is recommended to avoid it.

In this study, We designated the injection molded plug housing for charging electric vehicles as a research subject. And we analyzed the effect of Rib design on the quality of injection molded products. First, we used the Taguchi method to derive optimal conditions for rib design. The factors were set as the Thickness of the rib, the Height of the rib, and the Radius of the rib. Each factor consisted of 5 levels and generated conditions for a total of 125. We performed an injection molding analysis and confirmed significant factors affecting the deformation of injection molded products through ANOVA. Based on this, the 25th design detail was selected as the optimal condition. In addition, We compared the results of the molding analysis with the molded products that did not design ribs. We confirmed that the molded product designed with ribs under optimal design detail improved the deformation amount by 22.22% and the residual stress by 8.35%, compared to the molded product not designed with ribs.

The purpose of this study was to investigate the effect of Cheonggukjang pills with aronia and blueberries on dextran sulfate sodium (DSS)-induced colitis in mice. There have been several reports that Cheonggukjang is effective for intestinal health, but the efficacy of Cheonggukjang containing fruits has not yet been reported. In this study, we showed the effect of cheonggukjang pills with blueberries and aronia (CPBA) on DSS-induced colitis in BALB/c mice. CPBA was obtained from Soonchang Moonokae foods and orally administered once a day for 2 weeks before DSS treatment. Colitis was induced in mice by feeding 5% (w/v) DSS drinking water for 7 days. The results showed that CPBA treatment significantly alleviated DSS-induced disease activity index associated with a decrease in colon length. CPBA improved DSS-induced histological changes and intestinal epithelial barrier integrity in mice colon. In addition, CPBA administration significantly reduced the levels of DSS-mediated interferon-γ and interleukin-6 in serum and tumor necrosis factor-α in colon tissue. Moreover, the gene expression of COX-2 and iNOS, which are factors involved in inflammatory signaling, was significantly reduced by CPBA treatment. These results suggest that CPBA have a protective effect against DSS-induced mice colitis and may be a candidate for colitis treatment.

This laboratory study was conducted to evaluate the effects of oyster shell by-product (OSB) on the characteristics of Hanwoo cow manure and emitted gases. For the treated groups, 0.5% and 1% OSB were applied to 200 g of Hanwoo cow manure in a container box with three replications each per group with a group without OSB (0%) as a control group. All samples were stored at room temperature to analyze pH, volatile basic nitrogen (VBN), volatile fatty acid (VFA), and gas emissions (NH3 and H2S) from Hanwoo manure on 0, 2, 4, and 8 days. No group exhibited a significant (p>0.05) effect on VBN, acetate, and propionate values during the 8 days. On day 0, pH increased by 1% OSB application, but no effects on the other days. Iso-butyrate concentration increased (p<0.05) on day 0 by OSB application, but deceased (p<0.05) on day 8. The NH3 gas emission on day 2 decreased (p<0.05) in all treatments applied OSB. However, either NH3 or H2S gases in all treatments were below 0.25 ppm on days 4 and 8, which were no differences (p>0.05) among treatments. Thus, this lab study indicated that the inclusion of OSB application in Hanwoo cow manure had a beneficial effect on NH3 gas emission, but no longer than for 2 days.

This study was performed to investigate the quality characteristics and antioxidant activity of black soybean Sunsik product with functional food ingredients and functional labeling system. We prepared black soybean Sunsik (BS) containing black beans, cereals, and vegetables. Black soybean Sunsik with nondigestible maltodextrin and calcium lactate (BSN) was prepared by adding non-digestible maltodextrin and calcium lactate to the base recipe to apply a functional labeling system. The particle size in BS was 118.00 μm, whereas BSN was 127.00 μm. The respective L, a, and b color values of BS were 73.25, 2.36, and 14.21. The respective L, a, and b values of BSN were 73.21, 2.36, and 14.31. The respective water retention capacities of BS and BSN were 241.67% and 216.33%. No significant difference was observed between BS and BSN in the three physicochemical properties described above. However, the pH of BSN was 5.45, which was significantly lower than that of BS. The total respective phenolic contents of BS and BSN were 1.75 mg GAE/g and 1.61 mg GAE/g, and total respective flavonoid contents of BS and BSN were 6.36 mg RE/g and 5.95 mg RE/g. The antioxidant capacities of BS and BSN were compared via assays of DPPH and ABTS radical scavenging activities, FRAP, and reducing power. The antioxidant activities of BS and BSN increased in a dose-dependant manner. No significant difference between BS and BSN was observed in any measure of antioxidant capacity. These results suggested that the addition of functional food ingredients (non-digestible maltodextrin and calcium lactate) did not affect the quality characteristics and antioxidant activity of black soybean Sunsik.
