Purpose: This study discusses the phenomenon of the uncertain sustainability of SMEs in developing countries. SMEs face various challenges in the dynamics of a competitive environment, which threaten their growth and sustainability. This study aims to address a research gap between company's internal resources, in the form of absorptive capacity, and its business performance. By using product quality as a mediator, which has never been studied before, this research presents a novelty to answer the existing research gap using the Resource Based Theory (RBT) perspective. Research design, data and methodology: Using quantitative method, data are collected from 164 respondents, who are owners or managers of furniture manufacturing SMEs in Gerbangkertosusila Area, East Java, Indonesia. The data are analyzed using Partial Least Square (PLS) - Structural Equation Modeling (SEM). Results: The findings show that absorptive capacity has a direct and significant effect on business performance and indirectly through product quality. Conclusion: Furniture manufacturing SMEs are advised to focus on developing absorptive capacity reflected in good product quality, in order to improve their business performance. This is especially important to survive the crisis caused by the Covid-19 pandemic. Thus, the results of this study contribute to the development of RBT, and there are several suggestions for further research.

A seroprevalence study of small ruminant brucellosis was conducted in sheep and goat rearing selected areas of Mymensingh district and Dhaka district, Bangladesh, from March, 2005 to May, 2006. Sera from 62 sheep and 300 goats were tested by rose bengal plate test (RBPT), plate agglutination test (PAT), tube agglutination test (TAT) and mercaptoethanol test (MET). Out of the 62 sera tested 3.25% (n = 2) were positive to RBT, PAT and TAT and 4.84% (n = 3) were positive MET. In case of 300 goats, 1.67% (n = 5) were positive to RBT and PAT, 2% (n = 6) were positive to TAT and 2.33% (n = 7) were positive to MET. This investigation is the first of its type to be performed in small ruminants in Bangladesh. Higher prevalence rate (8.0 %) was found in BAU nutrition farm in case of sheep and 10 % in Bangladesh Agricultural University (BAU) Veterinary Clinic in case of goat while lower prevalence (0.0 %) was recorded in Pharmacology project and BAU adjacent villages in case of sheep and (0.0 %) in Dhamrai upazila in case of goats respectively. Brucella antibodies were more prevalent in sheep (8.84 %) than in goat (2.33 %).

A study on the relation between some husbandry practices and brucellosis in goats in Bangladesh was conducted at selected areas of Mymensingh and Dhaka district, Bangladesh, from March 2005 to May 2006. Sera from 300 goats were tested by Rose bengal test (RBT), plate agglutination test (PAT), tube agglutination test (TAT) and mercaptoethanol test (MET). Out of the 300 goats, 1.670% (n=5) were positive to RBT and PAT respectively, and 2.0% (n=6) were positive to TAT and 2.33% (n=7) were positive to MET. The prevalence of brucellosis was bigger in goats reared collectively (n=2, 4%) than reared individually (n=5, 2%), and bigger in goats housed with concrete floor (n=2, 4%) than that of bare floor (n=5, 2%). The rate of brucellosis was higher in goats keep separately (n=6, 2.61%) than that of kept with other animals (n=1, 1.43%) especially with cattle. Out of 290 goats from free grazing, 7 were positive but no positive reactor(n=10) was found in non grazing goats. In conclusion, however, seroprevalence of brucellosis had no statistically significant association with rearing type, housing type and grazing or not.

This study was carried out to develope enzyme-linked immunosorbent assay (ELISA) for detection of canine brucellosis in dogs experimentally inoculated with Brucella abortus 1119-3 and B. canis RM666. Groups A, B and C of dogs (each group consisting of three dogs) were orally inoculated with approximately $5{\times}10^9$ colony-forming units of B. abortus and B. canis, and with sterile pyrogen-free PBS, respectively. The animals were monitored at regular intervals upto the 12th week post inoculation (PI) by standard tube agglutination test (STAT), plate agglutination test (PAT), Rose Bengal test (RBT), 2-mercaptoethanol rapid slide agglutination test (2ME-RSAT) and ELISA. The induced antibody titers in group A dogs were detected from the first week PI to the eighth week PI in STAT, PAT and RBT using the inactivated whole cells of B. abortus 1119-3 as antigens, while no sera in groups B and C dogs reacted with the antigens. In 2ME-RSAT using whole cells of B. canis M-strain as antigens, the induced antibody titers in group B dogs were observed at the second week PI and persisted for the 12th week PI, while sera of groups A and C dogs did not react with the whole cells. In ELISA using cytoplasmic fractions antigen of B. abortus 1119-3, the mean optical density of antibodies in groups A and B was detected from the first and second weeks PI, respectively, and persisted for 12th week PI, while sera of group C did not cross-react with the fractions antigen. However, in ELISA using the hot saline extracts of B. canis M- as an antigen, the induced antibody titers in only group B dogs were detected from second week PI and persisted for until the end of this study. These results indicate that the ELISA using B. abortus 1119-3 cytoplasmic fractions as antigens can be a good candidate for detection of brucellosis by B. abortus as well as B. canis in dogs.

임베디드 시스템에 대한 RBT(Requirement-Based Testing)를 수행하기 위하여 정확한 요구사항 명세서가 존재해야 한다. 그러나 고객이 자연어로 작성하는 요구사항은 모호성, 부정확성, 불일치성을 가지고 있다. 이를 해결하기 위해서 UML, Simulink등의 모델링 언어를 이용하여 요구사항을 다시 모델링 하지만, 이 과정에서 요구사항을 use-case단위로 조합하고 재해석하는 단점이 생겨나게 되었다. 본 논문에서는 임베디드 시스템에 대한 고객의 요구사항을 use-case단위의 조합이나 재해석이 필요 없이 곧바로 모델로 표현할 수 있는 그래픽 언어를 이용한 1:1 요구사항 모델링 기법을 소개한다. 제안한 방법은 1) 임베디드 시스템의 요구사항을 자연어가 아닌 의미가 분명한 그래픽 언어를 이용하여 표현하고, 2) 하나의 요구사항을 하나의 그래픽 모델로 표현한다. 또한 제안한 방법은 시스템의 입출력을 기반으로 "what-to-do"만을 기술하기 때문에 상위레벨의 요구사항이나 하위레벨의 요구사항 모두에 적용할 수 있는 기법이다. 이 기법이 적용된 REED라는 도구를 통하여 실제 프로젝트에 적용한 예를 살펴본다.

본 연구는 OTT 경쟁이 치열하게 펼쳐지는 국내시장에서 토종 사업자인 '티빙(TVING)'의 경쟁력을 살펴보는 것을 목적으로 한다. 이를 위해 본 연구는 자원준거이론에 따라 티빙의 핵심 경영자원들을 살펴보고, VRIO 분석 모형에 따라 이러한 자원들의 경쟁력을 검토하였다. 분석 결과, 티빙의 유형 자원은 기술(추천, 압축), 콘텐츠(오리지널, 독점, 차별적 비독점), 제작 스튜디오, 유료가입자수로 분류되었다. 무형자원은 기획력(IP 개발·활용), 콘텐츠 유통채널(국내, 글로벌), 마케팅(프로모션·홍보, 세일즈), 브랜드로 파악되었고, 인적 자원은 IP 전문성으로 확인되었다. 또한 VRIO 분석틀에 적용했을 때, 차별적 비독점 콘텐츠와 제작 스튜디오, 국내 유통채널은 '지속적 경쟁우위'를 발생시키는 티빙의 강력한 경영자원이었으며, 기술 자원과 오리지널 콘텐츠, 콘텐츠 기획력 및 IT 전문성은 '일시적으로 경쟁우위'를 갖는 자원으로 확인되었다. 독점 콘텐츠와 유료가입자수, 글로벌 유통 채널, 프로모션·홍보 부분은 '경쟁등위' 자원이었으며, 세일즈 분야는 통신사 제휴와 합병을 통해 잠재고객을 확보했음에도 불구하고 아직 조직적으로 활용하지 못하는 '비활용 경쟁우위' 자원으로 나타났다. 본 연구는 경영전략 관점에서 국내 OTT 사업자의 개별 자원을 살펴보고 이를 통해 경쟁력 강화 방안을 제안하는 초기 연구로서 의의를 지닌다.
