  • 전기설계업체들은 현재 설계사마다 혹은 프로젝트마다 새로운 라이브러리를 구축하고 이러한 라이브러리를 업체 고유 노하우라고 하여 공개하지 않아 업체별 중복 제작에 따른 경제적 낭비가 발생하고 있다. 또한, 일부 공개된 라이브러리는 주관적인 관점에서 작성되어 지거나 전기 분야의 전문지식이 없는 소프트웨어 공급 업체들이 만들어 배포하다보니 전기설계 품질확보에 많은 문제가 되고 있다. 이러한 문제의 해결을 위해서는 전문성을 갖춘 전문가가 전기분야의 BIM라이브러리를 구축하고 활용할 수 있도록 표준화를 시킬 필요가 있다.

  • 심부전증(Heart failure)이란 심장이 조직에서 필요로 하는 산소나 영양분을 제대로 공급하지 못하는 상태로 심장 자체의 구조적 결함이외에도 혈역학(hemodynamics)에 영향을 주는 신장 질환이나 고혈압등에 의해서도 발생한다. 심장은 커다란 펌프로 혈역학적 변화에 능동적으로 대처할 능력을 가지고 있다. 하지만 이러한 혈역학의 변화를 유발하는 원인을 제거하지 않은채 장기적으로 원인이 지속할 경우, 심장, 특히 심실은 재구성(remodeling)이 일어나게되고(좌심실의 벽이 비후되고 우심실의 벽이 얇아지는 변화) 이로인하여 심장의 혈역학 변화에 따른 보상 반응은 점차 무력화 되게된다. 이로인하여, 혈액 정체에 따른 폐부종이나 복수증 및 산소 부족에 의한 허혈성 손상이 여러 장기에 나타나게 된다. 심장 질환은 불량한 예후와 치료의 제한성때문에 그동안 수의 분야에서 간과되어왔지만, 우리나라도 애완동물의 노령화가 시작되고 있고 고급 진료에 대한 축주들의 요구가 증가하고 있어서 점파 심장 질환의 진료가 늘어갈 것으로 사료된다. 따라서 본 종설에서는 심부전증에 대한 여러 가지 병리 기전과 이에 따른 치료 방법에 대해 기술하고자한다.

  • 미상무성이 2021년에 발표한 미국의 전체 무역량 중 한국의 비중은 3.4%로 미국의 수입국중 7위를 기록하고 있다. 그중 전자부품이 차지하는 비율은 26.7%로 미국 내에서도 주요 수입품목으로 분류된다. KOTRA는 미국의 디지털화에 따른 5G, 6G, 클라우드 컴퓨팅, 인공지능(AI) 등의 산업 시장 확대와 더불어 소재부품의 수요도 증가할 것으로 전망하고 있다[1]. 한국의 부품산업이 미국 시장에 보다 효과적으로 진출하기 위한 전략 수립을 위해 마이클 포터의 5 Forces Model을 미국의 산업 환경에 적용하였다. 한국의 부품기업들이 미국시장진출을위해서는 국가 내부적으로는 원천 기술력을 최대한 확보하고, 원자재 공급망을 안정화시켜 외부의 위협을 견제함과 동시에, 미국 시장에서는 한국 전자부품의 차별성을 인증받아 소비재 개발의 초기단계에 파트너사로 진입 산업 내 경쟁우위를 선점하는 것이 중요하다.

  • There have been growing concerns that Korea's products keep losing their international competitiveness. It is necessary to restore strong muscles of manufacturing sectors. Together, efforts must be made to strengthen the competitiveness of service sector. While wide consensus has been reached on the necessity that Korea's service sector needs overhaul for stronger global competitiveness, it is rather difficult to witness any remarkable improvements. Insufficient performances might result from the protection of the captive markets by the interested parties. The research starts from the proposition that the introduction of MDP will bring down the barriers between the segmented services and promote competition. We provide theoretical analyses and report better performances of major countries which introduced MDP in their soils. Considering the reality, we propose that in the foreseeable future, a MDP in the areas of tax, law and accounting be introduced in Korea because these areas seem to create least conflicts of disciplinary duties due to public purposes. Broader MDPs in other areas may take some more time. There exist, however, some limitations. As MDP has not been officially introduced in Korea, it is almost impossible to directly compare the performances between the pre- and post-MDP in Korea. Data scarcity of business performances of companies also limits the study.

  • Profitability of upland crops is better than paddy crops and proportion of upland is increasing. However, there is a lack of infrastructures for upland irrigation. The object of this study were to develop water supply scenarios using individual and collective agricultural wells to evaluate economic feasibility to consider geographical analysis of upland farms and water supply facilities. Cheongyang, Dangjin, Yesan, and Goesan were selected as study areas where four different crops of red pepper, chinese cabbage, apple, and bean, respectively, were mainly produced in Chungcheong province. As a result, B/C ratio was estimated as 1.49, 1.36, 1.90, and 0.71 in using individual wells scenario, and 1.45, 1.20, 1.91, and 0.65 in using collective wells scenario for red pepper, chinese cabbage, apple, and bean. It turned out that change of price effected on economic feasibility a lot for crops with low production income. As a result of evaluating economic feasibility by number of plots for developing collective well, there was no effect of economy of scale for red pepper and chinese cabbage. In case of collectivizating more than 20 upland plots, effect of economy of scale appeared for apple and bean. In conclusion, development of water using high value crops including red pepper and apple, and effect of collective well requires additory analysis of .spatial distribution of farms.

  • Today, in the cultural properties research, there are several methods for knowing the culture of the past through a lot of information that remains and relics contain. Especially, statistical method like presumption of producing center were introduced from computer development at the early 20th century. This study showed the characteristic about firing historic sites presumed as a tile-kiln in the remains of Cheonwang temple sites, Hanam, Gyeonggi province. Also, I used nature scientific methods for correlation between tiles excavated at historic sites and circumference building and obtained there results as follows. First, soft tile parts showed similar water suction ratio(over 10%) like another tiles, except hard tile parts. Second, identification about mineral crystallization in a sample showing low water suction ratio confirmed a result that Mullite, Tridymite, Cristobalite as high temperature crystal form were presented. I know that firing temperature was higher than the other tile parts from this result. Third, statistical analysis from micro-component resulted that tiles excavated at firing historic sites and Cheonwang temple sites were closely connected. As the results, I knew that the tiles got a supply after the establishment of tile-kiln, not at a long distance at the period of Cheonwang temple construction.

  • The service industry, as a new growth engine, has become more important in response to changes in the global economy and the industrial environment. Developed countries have promoted the competitiveness of the service industry and have enhanced economic added value. Developing new services requires extensive resources. Therefore, cooperation and network building capabilities with customers, suppliers, and various knowledge creation agencies are critical sources of competitiveness. This study classified the Korean service industry by industrial type in order to enhance innovation competence.The Korean service industry lags behind that of developed countries, and this study analyzed the differences of innovation results according to collaboration partners by the classified industry. By adopting a method that applies industrial classification by Dialogic's innovation pattern, this study showed external cooperation results were different by industrial type. Analysis results revealed that companies cooperate with customers and competitors in many cases; however, product innovation was higher for companies that collaborated with private service companies. In the 'Innovation in services' industry, industry cooperation with universities showed organizational innovation achievements. In the 'Innovation through services' industry, cooperation with customers positively affected marketing innovation achievements. Consequently, the need to foster consulting firms and universities that can professionally collaborate with companies is implied in order to enhance the Korean service industry.

  • Suspended sediment concentration (SSC) is a crucial riverine parameter in terms that it can be utilized for analyzing sediment transport, stability assessment of river and structure and so on. However, in case of domestic, sediment discharge data are not enough because of using conventional sediment samplers. This study aimed at developing a practical technique for estimating suspended sediment concentration in high spatial and temporal resolution by building relationship between acoustic backscatter (or SNR) from H-ADCP with actually observed data using LISST-100X. In this regard, a dedicated correction algorithm was proposed particularly for the adapted H-ADCP (SonTek SL-3000). Then, a SNR-SSC relation was built based upon a real-scale field experiment, where both H-ADCP and LISST-100X were concurrently operated to observe SNR and SSC, respectively. The coefficient of determination for the developed regression equation of SNR-SSC relation was around 0.85~0.88, thereby the relation could be evaluated to be highly correlated. The result of this study might be potentially applied for real-time and simultaneous observation of SSC when H-ADCP could be applied.
