The domestic gaming industry is a globally competitive field, but growth has recently slowed and competition in overseas markets is intensifying. Accordingly, it is important to analyze the investment status of the domestic gaming industry and study ways to revitalize it. The game industry is a labor-intensive, high-value-added industry that occupies an important position in the domestic content industry. However, the number of businesses and employees has been steadily decreasing for several years, and polarization within the industry is worsening. This is the effect of a decrease in investment in an industrial structure in which labor costs are the majority of production costs. Accordingly, we analyze the current status of the domestic gaming industry, and also analyze the investment status of the gaming industry and the investment structure of domestic venture capital to study the scale and required period of investment and investment projects needed to promote the industry. In this study, "the investment status of the domestic gaming industry and proposed revitalization measures. We study cooperation between the government, businesses, and academia to solve the problem of declining investment and slowing growth." We expect to strengthen competitiveness and continue to grow as we pursue revitalization plans.

목 적 : 최근 신생아학의 발달과 신생아 집중 치료의 발달로 기관내 삽관 후 인공 환기요법 치료가 빈번하게 이루어져 호흡곤란증이 있는 신생아의 사망률은 감소된 반면 이에 따른 여러 합병증이 병발할 가능성이 높아지게 되었다. 이에 저자들은 인공 환기요법을 사용한 신생아에서 VAP의 발생빈도와 위험요인 및 주된 균주에 대해 알아보았다. 방 법 : 2000년 1월 1일부터 2003년 6월 30일까지 한림대학교 강남성심병원 신생아 집중치료실에 입원하여 인공 환기요법을 사용한 신생아 50명을 대상으로 하여 입원 기록지를 후향적으로 분석하였다. VAP의 진단은 기관내 삽관 당시에는 폐렴이 보이지 않으나 기관내 삽관 후 최소 48시간 경과 후 흉부 방사선상 새롭게 침윤이 발생한 경우로 정의하였다. 상기 조건에 만족하는 환아 13명을 VAP군으로, 만족하지 않는 환아 37명을 대조군으로 분류하였다. 결 과 : 인공 환기요법을 사용했던 환아 50명 중 VAP의 발생빈도는 26.0%(13명)였다. 동맥관 개존증과 뇌실내 출혈이 VAP 발생과 연관이 있었고 재태연령, 출생체중, 1분 및 5분 Apgar 점수 및 호흡곤란 증후군, 기관지폐 이형성증, 미숙아 망막증, 패혈증, 급성 신부전, 폐출혈, 공기 누출 증후군 등과는 연관이 없었다. 본 연구에서는 총 12균주가 동정되었는데 MR-CNS 4례(33.3%), E. cloacae 3례(25.0%), P. aeruginosa 2례(16.7%), MRSA 1례(8.3%), Acinetobacter baumanii 1례(8.3%), K. pneumoniae 1례(8.3%)로 MR-CNS가 가장 많았다. 결 론 : 본원 신생아 집중치료실에서 인공 환기요법 치료 후 발생한 폐렴의 빈도는 26.0%이며 MR-CNS가 가장 많이 배양되였다. 기관삽관 말단의 배양은 VAP의 정확한 진단을 위해서는 적절치 않을 수 있으나 신생아에게 필요한 침습적이지 않고 정확한 방법에 대한 연구가 필요하다고 생각된다.

본 연구는 P. nana의 집약적인 대량배양을 위한 최적 배양밀도를 규명하기 위한 것으로 nauplius 생산과 성체생산의 두 가지 측면에서 조사되었다. 2 ml 배양규모에서 성체 암컷 밀도에 따른 성체 암컷의 nauplius 생산력은 성체 암컷의 밀도가 증가함에 따라 감소하는 경향을 보였지만 copepodid와 nauplius의 밀도는 성체 암컷의 생산력에 영향을 미치지 않는 깃으로 나타났다 8 L배양 용량에서 일주일 동안 암컷의 일일 평균 생산량은 1, 3, 5, 7개체/ml실험구에서 각각 0.6, 1.1, 17, $2.3{\times}10^5$ 개체로 배양밀도가 증가할수록 생산량이 증가하였으나 10 개체 /ml로 배양한 실험구는 $1.3\times10^5$개체로 7 개체/ml로 배양한 실험구보다 낮은 생산량을 보였다. 5 L배양용기에서 15일 동안 P. nana nauplius의 접종 밀도에 따른 생존개체는 모든 실험구가 시간이 경과함에 따라 감소하는 경향을 보였으며, 15일째, C4-성체까지의 생존율은 50, 100, 150및 200개체/ml 실험구에서 각각 32.7, 307, 28.9 및 $23.0\%$로 배양밀도가 증가함에 따라 감소하는 경향을 보였으나 유의적인 차이는 없는 것으로 나타났다. 그러나 250 개체/ml와 300 개체/ml 로 배양한 실험구는 각각 $19.7\%$와 $18.4\%$로 50, 100, 150 개체/ml 실험구보다 낮은 생존율을 보였다. P. nana성체의 nauplius에 대한 공식은 있는 것으로 나타났으며 먹이의 공급 시 공식이 줄어드는 것으로 판단된다. 결과적으로 P. nann는 성체 생산을 위한 nauplius의 최대 접종밀도가 200개체/ml인 점을 고려해 볼 때, 비교적 고밀도로 배양이 가능하며 어류 종묘생산장에서 먹이 생물로 사용이 가능할 것으로 보인다.

Food production is a major role of agriculture. It has been projected that the world population continues to increase by the middle of the 21st century, and the population growth results in raising a serious problem of food shortage. Thus we have to increase food as possible. A considerable amount of crops have been abandoned due to short-life after postharvest. Ethylene is a factor responsible for the postharvest loss in crops, especially horticultural crops. If we can reduce ethylene production or sensitivity by genetic engineering, we can develop, so called,“long-life crop”conferring long postharvest lives. During last two decades, intensive research for molecular dissection of ethylene biosynthesis has been carried out, and the researchers have succeeded in engineering ethylene productivity in some crops. On the other hand, after the successful isolation of Arabidopsis ethylene receptor gene ETR1, the homolog genes have been isolated in various plant species. Currently the characterization of these genes and alteration of ethylene sensitivity using the genes are in progress. This review summarizes current progress in the analysis of these genes, and discusses genetic engineering of ethylene sensitivity using these genes.

The process of biological treatment of organic wastewater is principally associated with those of self-purification in the natural water environment. The treatment system has e intensive function of stabilizing wastewater more effectively than in natural water, which is like natural water concentrated in a small space. Biological treatment of wastewater involves activated sludge and various modified process, trickling filter, rotating disk, oxidation ditch, etc. for aerobic decomposition and anaerobic processes such as anaerobic decomposition and methane fermentation. The basic characteristic of these processes is the use of mixed culture for the conversion of pollutants. This review forcuses on the various kinds of microorganisms related to each treatment processes. Kinetic analysis of the activated sludge process is discussed in order to understand the basis of control and maintenance of the biological treatment process.
