  • 소프트웨어 개발 프로젝트는 성공률이 30% 밖에 되지 않는 어려운 과제이다. 소프트웨어 개발 프로젝트가 실패하는 이유는 여러 가지가 있을 수 있으나, 체계적인 관리 소홀이 큰 비중을 차지하고 있다. 특히, 완성도가 떨어지는 산출물을 다음 단계로 진행시키는 것은 많은 시간과 노력을 허비하여 프로젝트를 실패로 이끌 수 있다. 이를 방지하기 위해 채택되고 있는 방식은 동료 검토(Peer Review) 또는 인스펙션(Inspection) 등과 같은 산출물들에 대한 검토활동이다. 문제가 발견된 산출물들은 다시 개발자에게 돌아가서 수정하게 되는데, 이 과정을 재작업 (Rework)이라고 한다. 프로젝트 관리자가 완성도가 떨어지는 산출물들을 다음 단계로 넘겨서 오류에 대한 막대한 비용을 지출하고 기간을 지연시키는 등의 사고를 막기 위하여, 본 연구에서는 재작업의 충실도를 높일 수 있는 방법을 연구하였다. 즉 프로젝트의 재작업 시에 작업분석을 시행함으로써 재작업된 결과의 검토 수준을 달리하는 재작업지표를 개발하였고, 이에 대한 검증을 위해 4개의 프로젝트를 선택하여 개발된 지표의 적용 여부를 관찰하고 그 효율성을 입증하였다.

  • 고점성을 갖는 미생물 생물 고분자에 대한 발효공정 분석 및 조절 연구의 일환으로 알카리 내성 Ba cillus sp.를 사용한 생물고분자의 발효 중 배양액의 유변학적 성질에 대한 경시변화를 조사하였으며, 균 체생육 및 생물 고분자의 생산과 유변학 특성 변화와의 상관관계를 검토하였다. 배양액의 유변학은 배양시간 경과에 따라 현저하 게 변화하여 더욱 점성이 있고, 또 의가소성이 증대 하면서 비뉴우톤 유체로서 거동하였다. 발효 중 유 통지수, 점조도지수, 항복융력 빛 겉보기 점도 등 유 변학 특성값은 균체증식에는 거의 영향을 받지 않고, biopolymer의 합성과 밀접한 상관성을 보였다. 또 유변학적 특성값의 변화는 생물고분자 농도만의 함수가 아니고 발효진행과 상관성을 보였고, 생물고 분자의 생성이나 기질 소비의 완료 직전에 최대값을 나타내었다. 따라서 이들 변화의 특성화는 발효경과 또는 완료에 대한 양호한 지표를 공급할 수 있음을 시사하였다.

  • Left atrial enlargement (LAE) is an important diagnostic factor in dogs with myxomatous mitral valve disease (MMVD). It is associated with the onset of congestive heart failure (CHF). Recently, a new radiographic left atrial measurement called vertebral left atrial size (VLAS) was introduced. This can be considered as a left atrial enlargement above 2.3. It appears to be related to the severity of MMVD. However, serial changes in VLAS in relation to disease progression and improvement in patients have yet to be studied. This study aims to assess the value of VLAS as a left atrial size monitoring indicator by examining correlations with VHS, LA/Ao ratio and LVIDDN, and comparing serial changes in dogs. A total of 126 dogs were studied with their owners' consent. The dogs were classified into four MMVD groups (Control, B1, B2, C-D) following the ACVIM Guideline by performing a physical examination, radiography and echocardiography. Besides, 24 and 17 dogs were reevaluated to compare values in relation to the progression and improvement of MMVD. VLAS showed significant increase according to the progress of the MMVD stage. This was the same in the Maltese breed group. A strong positive correlation was found between LVIDDN, VHS, LA/Ao ratio, and VLAS. The results of this study found VLAS to be significantly different according to left atrium size, and there was a correlation between disease progression and VLAS levels in each dog. Therefore, VLAS may be used to detect changes in left atrium size as an additional monitoring index of MMVD.

  • The relevance of the research involves outlining the need for modern professionals to acquire new competencies. In the conditions of rapid civilizational progress, in order to meet the requirements of the labor market in the knowledge society, there is a readiness for continuous training as an indicator of professional success. The purpose of the research is to identify the impact of various forms of application of information technologies for lifelong learning in order to provide the continuous self-development of each person without cultural or age restrictions and on the basis of rapid digital progress. A high level (96%) of need of the adult population in continuing education with the use of digital technologies has been established. The most effective ways to implement the concept of "lifelong learning" have been identified (educational camps, lifelong learning, mass open online courses, Makerspace activities, portfolio use, use of emoji, casual game, scientific research with iVR game, implementation of digital games, work in scientific cafes). 2 basic objectives of continuing professional education for adults have been outlined (continuous improvement of qualifications and obtaining new qualifications). The features of ICT application in adult education have been investigated by using the following methods, namely: flexibility in terms of easy access to ideas, solving various problems, orientation approach, functional learning, group or individual learning, integration of leisure, personal and professional activities, gamification. The advantages of application of information technologies for continuous education (economic, time, and adaptive) have been revealed. The concept of continuous adult learning in the context of digitalization has been concluded. The research provides a description of the structural principles of the concept of additional education; a system of information requests of the applicant, as well as basic technologies for lifelong learning. The research indicates the lack of comprehensive research in the relevant field. The practical significance of the research results lies in the possibility of using the obtained results for a wider acquaintance of the adult population with the importance of the application of lifelong learning for professional activities and the introduction of methods for its implementation in the educational policy of the state.

  • 기존 도로포장 시방서는 계약자에게 포장 수명에 상관없이 재료 및 시공 상의 주어진 조건만을 만족하면 되도록 요구하고 있다. 이와 같은 시방 기준으로는 도로포장 기술 개발에 한계가 있으며 포장파손 발생 시 발주자와 계약자 간에 분쟁이 발생할 소지가 있다. 이러한 문제점을 개선하기 위하여 성능보증 계약제도를 도입하려는 연구가 도로포장 분야에서 진행되고 있다. 성능보증 계약제도는 계약자에게 재료와 공법을 마음대로 선정할 수 있는 기회를 부여하고 주어진 기간 동안 일정 수준 이상의 성능을 유지하도록 하는 제도이다. 성능보증 계약제도의 성공적인 도입을 위해서는 성능보증 시방서의 주요 요소인 포장의 성능인자와 임계한도가 먼저 정의되어야 한다. 본 연구에서는 미국 몇 개 주에서 사용되는 성능보증 계약제도에 관한 문헌을 검토하여 아스팔트 포장의 성능인자, 임계한도, 그리고 성능보증 기간에 관한 조사를 실시하였다. 또한 국내 고속국도 중 24개 노선과 16개 지역의 일반국도 노선에서 아스팔트 포장의 성능에 영향을 미치는 주요 파손을 조사하고 분석하여 미국의 사례와 비교하였다. 본 연구결과를 근거로 국내 아스팔트 포장에 대한 합리적인 성능보증 시방이 개발될 것으로 예상된다.

  • This Study was carried out to investigate yeast and mold contamination in fermented milk products produced by 9 different domestic manufacturers from October 20. to December 5. 1980 The results obtained in the study were as follows 1) pH values of the products were ranged from pH 3.14 to pH 4.20 and average of sour milk drinks was pH $3.66\pm 0.19$ and fermented milks pH $3.74\pm 0.11$. Therefore the difference of pH average among sour milk drinks and fermented milks was statistically significant. (p<0.01) 2) In case of yeast contamination, yeast was found on all the four producted at the same date. From this result, it seemed that yeast contamination occured during the manufacturing progress. 3) Degree of contamination by the indicator organisms was E. coli positive, 3.7%: over 1,000 yeasts/ml, 14.8% over 10 molds/ml, 0.9%. 4) In the range of over 1,000 yeasts/ml, degree of contamination by yeast was 8.4% in fermented milk and 16.7% in sour milk drink. 5) Yeasts in product C increased to the spoilage number within 5 days and in H increased within 10 days at 5C. At 15$\circ$C, yeast increased to the spoilage number within 15 days in product A.D. 6) It seems that the yeast number of initial contamination should be important than the increase rate as criteria on the fermented Milk products.

  • Freesia, a member of the Iridaceae family, has fragant, tubular shaped flowers and is very popular ornamental plants in the world. Diseased freesia plants showing systemic leaf streak mosaic symptoms were collected from a cultivated farm in Kyonggi province, Korea in 2003, and its causal agents were investigated. Two viruses, Cucumber mosaic virus (Fr-CMV) and a potyvirus, were identified from the leaf tissues of the diseased freesia based on sequence analysis and host range tests. CMV-Fr could infect systemically on Chenopodium quinoa, C. amaranticolor, N. glutinosa, and N. benthamiana, and this biological property is distinguishable from ordinary strains of CMV. A filamentous potyvirus-shaped virus could not infect general indicator plants by mechanical inoculation. Single RT-PCR products was successfully amplified with a set of degenerate primers specific to the Potyvirus genus and total nucleic acids from the infected tissues, and was cloned into the pGEMT-Easy vector. Nucleotide sequences confirmed it belongs to the Potyvirus genus with either a new species or an isolate of Freesia mosaic virus (no information is available for the FrMV). This is the first report of FrMV in Korea and more characterizations of the two viruses are in progress.

  • As the usage of smart phones continues to increase, the control UI, which users have to continue to use, sometimes finds a heavy burden on users. Therefore, in this study, we have studied the control user interface structure along with the theoretical background of the control user interface, and we have studied the role and usage of the control component based on it. Typical commonly used controls are button controls for transmission, selection controls for various selections, link controls for navigation, text controls for inputting characters, indicator controls for feedback on progress, A message control that displays information about warnings and errors, and a window control such as a dialog box. The structure of the control should be designed according to the use of the separated control to help the user efficiently use the control user interface. Based on the analysis of the theoretical usage of representative components belonging to the separated controls, we presented a new and correct way to use the control to improve the user experience. The use of improved control components will help to design the control structure efficiently and to improve the user experience.
