Inventory inspection is an important task to eliminate the inconsistency between real assets and inventory management systems, and it is performed periodically at the site. In the case of a large-sized property, it is mainly managed in an outdoor workshop or a warehouse. However, due to the large area of the outdoor area, it is relatively difficult to identify the quantity and location of the property and is also vulnerable to theft. To solve this problem, we proposed a method and system for performing a warehouse inventory inspection using an unmanned aerial vehicle (UAV) and Bluetooth low energy (BLE) beacons. The proposed method has the following advantages. First of all, if we carry out inventory inspection by utilizing UAV, we can minimize user’s effort compared to existing methods. The method of recognizing the asset by attaching the BLE beacon is more costly than using the existing RFID technology, but it is advantageous because the recognition distance is increased and the battery life of the tag is drastically increased. We also designed a BLE beacon reader for the system and implemented a prototype to show the feasibility of the proposed system. The prototype is based on Genuino 101, which is a kind of arduino, and adds HM-10 and Neo-6m modules to provide Bluetooth and GPS functions. The BLE beacon reader was tested in outdoor, and attached in drone. We also developed an inventory checking system based on the web to display results of inventory checking. The proposed approach enables the users to automate the operation of inventory checking on an outdoor warehouse.

인터넷에서 매 순간 발생하는 데이터의 홍수는 사용자가 필요로 하는 유용한 정보를 검색하는데 어려움을 초래한다. 그래서 많은 사용자들이 자신이 원하는 정보를 쉽게 찾기 위한 기법을 고안하고 이를 지원하는 도구를 개발하게 되었다. 이런 유용한 도구 중 하나인 추천시스템은 기존의 사용자 정보를 분석하여 사용자가 원하는 제품이나 정보를 추천하는 것이다. 본 논문에서는 추천시스템을 활용하여 원하는 정보를 제안하는데 인구통계학적인 기법을 사용한다. 인구통계학 기반 추천시스템은 나이, 성별과 같은 인구통계학적인 특성을 사용하여 유용한 정보를 추출한다. 본 연구는 영화 선택 시 중요한 요소인 사용자 평점을 분석하고 이를 활용할 수 있는 방법을 제시하였다. 이를 위해 Internet Movie Database(IMDB) 웹 사이트에 있는 영화의 사용자 평점을 인구통계학적 요인으로 분석하였다. 본 논문에서는 인구통계학적 분석을 위해 사용자를 성별과 연령대로 분류하였고, 각 영화를 22개 장르로 나눈 IMDB 기준에 따라 사용자 평점을 분석하였다. 각 장르별 영화에 대해 사용자 그룹의 평균 평점을 F-테스트와 T-테스트를 수행하여 그 장르 영화 평점과 동일한 결과를 나타내는 대표 그룹을 찾아내었다. 인구통계학적 분석 결과인 대표 그룹은 새로운 영화가 개봉될 때 대표 그룹에 대한 프로모션과 추천을 통해 영화 홍보를 할 수 있는 대상을 찾아내는데 유용하다. Nowadays, overflowing data produced every second from the internet make people to be difficult to search for the useful information. That’s why people have invented and developed unique tools that they get some relevant information. In this paper, the recommender system, one of the effective tools, is used and it helps us to get the useful information that we want by using demographic information to predict new items of interest. The demographic recommender system in this paper computes users’ similarity using demographic information, age and gender. So we performed demographic analysis on movie ratings on Internet Movie Database (IMDB) web site that movies are rated by thousands of people, where users submitted a movie rating after they watched a recent popular film. Meanwhile, we can understand that user’s ratings, among various determinants of box office, is very essential factor in the study on recommendation of movie. This paper is aimed at analyzing movie average ratings directly given by film viewers, categorizing them into groups by sex and age, investigating the entire group and finding the representative group by examining it with F-test and T-test. This result is used to promote and recommend for the target group only. Therefore, this study is considerably significant as presenting utilization for movie business as well as showing how to analyze demographic information on movie ratings on the web.

배성문(Sung-Moon Bae),김정한(Jeong-Han Kim),조철우(Cheol-Woo Cho),정태준(Tae-Joon Jeong),하정욱(Jung-Uk Ha),이승철(Seung-Cheol Lee) 한국식품영양과학회 2001 한국식품영양과학회지 Vol.30 No.6

Microwave 처리가 쌀가공 부산물로 발생하는 왕겨와 미강의 항산화능에 미치는 영향을 조사하였다. 100 W, 200 W, 440 W의 출력으로 microwave를 처리하였을 때, 출력과 처리시간에 비례하여 갈변을 나타내는 색도의 변화가 관찰되었다. 그러나, 왕겨와 미강의 전자공여능은 조사된 범위 내에서 microwave 처리에 대해 큰 변화를 보이지 않았다. 활성산소종(H₂O₂, O₂^-,ㆍOH)을 발생시켜 어유의 과산화에 대한 왕겨와 미강의 과산화 억제력을 조사한 결과, 전반적으로 왕겨가 미강보다 microwave 처리에 안정함을 보였다. 특히, H₂O₂에 대한 왕겨의 과산화 억제력은 미강에 비하여 매우 높게 측정되었다. 이상의 결과로 왕겨가 미강보다 항산화 물질을 많이 함유함으로써 미강보다 높고 안정한 항산화능을 나타내고, 또한 microwave 처리로 인하여 항산화 물질이 일부 파괴되지만 항산화력을 가지는 갈변 반응 생성물이 생성되어 왕겨의 경우에는 microwave 처리에 대해 영향을 거의 받지 않음을 알 수 있었다. 따라서, microwave 처리 공정은 왕겨나 미강의 항산화능을 이용한 가공 방법에 이용될 수 있음을 의미한다. Microwave treatment was studied to investigate the antioxidant ability of rice hull and rice bran. The color changes were related to the intensity of microwave and to the treated time on rice bran. However, the electron donating abilities of rice hull and rice bran extract were not much affected by microwave intensity. Rice hull extract treated with a 100 W microwave showed 80% inhibition of lipid peroxidation when fish oil was treated with H₂O₂. Also inhibition activity against lipid peroxidation in rice hull is more stable than that of rice bran when treated with microwave. Overall, rice hull extract showed better antioxidant activity than rice bran. It seems that rice hull contains higher antioxidant components as well as the browning reaction products having anti-oxidant activity during microwave treatment.

Effect of microwave treatment to barley bran was tested on antioxidative ability. Treatments of microwave at 100 W and 200 W, changed color of barley bran to brown, but carbonation was happening at 440 W. The electron donating abilities of barley bran was not reduced when treated with 100 W and 200 W microwave treatment for 10 minute. According to TBARS, the barley bran extract treated with 100 W and 200 W intensity of microwave for 10 min maintained the inhibition of lipid peroxidation, while the extract from 440 W microwave treatment for 5 min did not. Total phenolic contents were reduced with increased intensity of microwave treatment. The antioxidant activity of barley bran was not affected by microwave treatment at 100 W and 200 W, while the 440W microwave treatment reduced the activity due to carbonation of barley bran and decreased phenolic compounds.

감마선 조사에 의한 왕겨, 미강, 맥강의 항산화능의 변화

배성문(Sung-Moon Bae),김정한(Jeong-Han Kim),조철우(Cheol-Woo Cho),정태준(Tae-Joon Jeong),육홍선(Hong-Sun Yook),변명우(Myung-Woo Byun),이승철(Seung-Cheol Lee) 한국식품영양과학회 2002 한국식품영양과학회지 Vol.31 No.2

감마선 조사가 왕겨, 미강, 맥강의 항산화능에 미치는 영향을 조사하기 위하여 4.2 kGy/h의 속도로 각각 5, 10, 15, 20kGy를 조사한 후, 메탄올 추출물을 제조하여 항산화능의 변화를 측정하였다. 감마선을 조사하지 않은 시료의 총 페놀함량을 측정한 결과, 왕겨가 0.873 mM, 미강이 0.643 mM, 맥강이 0.377 mM로 측정되었으며, 감마선 조사에 따른 총 페놀 함량은 조사선량에 상관없이 일정하게 유지되었다. 전자공 여능의 측정결과 감마선을 조사하지 않은 왕겨, 미강, 맥강에서 모두 비슷한 활성을 보였으며, 감마선을 조사한 경우에도 모든 시료에서 조사선량에 따른 유의적인 변화를 나타내지 않았다. TBARS분석에서는 감마선을 조사하지 않은 왕겨와 미강 추출물이 맥강 추출물보다 지질 과산화 억제력이 높았으며, 감마선 조사시에도 왕겨와 미강은 활성이 유지 또는 보유되었으나 맥강은 조사선량이 높을수록 지질의 산화 억제력이 상당히 감소되었다. 따라서 왕겨, 미강, 맥강의 페놀성분과 전자공여능에 관여하는 성분이 감마선에 매우 안정하며, 지질 과산화 억제능에 관여하는 성분은 왕겨와 미강의 경우에는 감마선에 안정하지만 맥강의 경우 불안정하였다. Effect of γ-irradiation to cereal processed by-products was examined for antioxidative ability. Rice hull (RH), rice bran (RB) and barley bran (BB) were irradiated with 5, 10, 15 and 20 kGy of γ-ray at 4.2 kGy/h. The amount of total phenol compounds of unirradiated RH, RB, and BB were 0.873 mM, 0.643 mM, and 0.377 mM, respectively. Irradiation up to 20 kGy did not show noticeable effect to the amount of total phenol compounds in RH, RB and BB. Electron donating abilities of RH, RB and BB were very similar, and they were not affected by irradiation. According to TBARS analyses, the inhibition abilities of lipid peroxidation of RH and RB were not affected by γ-irradiation, while those of BB were decreased with irradiation. These results indicate that BB is more sensitive to γ-irradiation than other rice processed by-products.

Cost reduction, time to market, and quality improvement of software product are critical issues to the software companies which try to survive in recent competitive market environments. Software Product Line Engineering (SPLE) is one of the approaches to address these issues. The goal of software product line is to maximize the software reuse and achieve the best productivity with the minimum cost. In software product line, software components are classified into the common and variable modules for composition work. In this paper, we proposed a dynamic composition process based on aspect-oriented programming methodology in which software requirements are classified into the core-concerns and cross-cutting concerns, and then assembled into the final software product. It enables developers to concentrate on the core logics of given problem, not the side-issues of software product such as transactions and logging. We also proposed useful composition patterns based on aspect oriented programming paradigm. Finally, we implemented a prototype of the proposed process using Java and Aspect to show the proposed approach's feasibility. The scenario of the prototype is based on the embedded analysis software of telecommunication devices.

The engineering knowledge and technology is core driving forces of continuous growth in knowledge based society. Companies, the government, and universities are the subjects of an innovation and the cooperation between them is very important. Nowadays, the main purpose of industry-university cooperation moves to train experts and develop a new product. A shift of the paradigm came from the change of recognition that the final consumers of the program are companies and the universities are supporters of the program. In this paper, we investigate the purpose, participation and satisfaction of companies to industry-academy technology cooperation through empirical studies. The need to expert training, product development and process development makes companies participate industry-academy technology cooperation and companies have different purpose of participation by the business type. Companies often feel that expert training, subsidiary purpose of industry-academy technology cooperation, is more important than product development or process development. This result is caused by the real world environment of small and mid-size companies, lacking of technology experts. The participation of companies to each technology cooperation program (technology transfer, joint technology development, consigned technology development, technology consulting, co-op. lab.) is also different by business type. The companies’ satisfaction with the purpose of process development is relatively higher than that with the purpose of product development and companies show also different satisfaction value by business type and participating program. The results of this study can give a contribution to the design of demand oriented industry-academy technology cooperation model. 1)

이상천(Sang Cheon Lee),배성문(Sung Moon Bae),고봉상(Bong Sang Go) 한국전자거래학회 2008 한국전자거래학회지 Vol.13 No.4

본 연구는 국내 벤처기업의 경영성과를 결정하는 요인들을 통합된 연구 틀 안에서 규명해보고자 하는 목적으로 실시되었다. 이를 위하여 창업자/팀, 조직/자원, 전략/창업과정, 산업환경, 지원시스템을 경영성과 영향요인으로 정의하였으며 영역별 측정변수를 독립변수로, 경영성과를 종속변수로 하는 벤처 경영성과 통합 모형을 구축하고, 우수벤처와 열등벤처의 경영성과 영향요인을 실증적으로 검증하였다. 분석 결과, 우수기업의 경우 창업자 자신의 산업전문능력과 시장규모의 확대가 경영성과에 더 민감한 요인으로 작용하고 있으며, 열등기업의 경우 자원조달능력 및 경영 전략 역량이 민감한 요인으로 나타났다. 또한 우수기업과 열등기업을 나누는 핵심요인은 창업자의 능력 및 정부정책의 일치성으로 나타났다. 본 연구 결과는 표본수의 부족, 측정 척도의 미비 등 실증 연구의 한계를 가지고 있지만 통합된 연구 틀 안에서 우수 벤처기업의 핵심 성공 요인을 제시하는데 그 의미가 있다. The purpose of this study is to identify the determinants of new venture performance in the view of integrated research framework and to investigate key determinants of superior and inferior ventures. We propose the integrated new ventures performance model which is composed of entrepreneur, organization/resources, industrial environment, strategy/foundation process and availability of supporting systems as corresponding variables to new ventures performance. The superior venture performance is affected mainly by entrepreneur’s managerial ability and industry expertise, but the inferior by resources and management strategy. Though this study has limitation of small sample, limited questionnaire and performance measure, it has contribution of identifying key determinants of new venture performance with the integrated frame of study.
