식량위기 재발가능성에 대한 소고

이원근 대구대학교 경제경영연구소 2011 경제경영연구 Vol.7 No.1

2008년에는 국제곡물시장은 격동이라고 할 수 있을 정도의 격한 움직임을 보였으며 곡물시세가 급등하면서 많은 곡물생산국이 수출규제를 강화하였고 식량의 상당부분을 해외에 의존하는 우리나라는 여러 가지 측면에서 어려움을 겪었다. 최근 곡물가격은 안정세를 유지하고 있음에도 불구하고 국제적인 기상악화나 원유가격의 상승에 따른 대체에너지개발에 일부의 농산물이 이용되면서 식량위기 재발의 가능성을 우려하는 목소리가 높아지고 있다. 식량위기 재발 가능성에 대한 긍정적인 측면으로 제시되고 있는 주된 논거로는 첫째 수자원 부족현상의 심화 둘째, 세계인구 증가의 가속화 셋째 국제원유가격의 상승과 세계 에탄올 수급의 증대 등을 들 수 있고, 부정적인 측면으로는 첫째 원유가격의 안정과 바이오연료 증산정책, 둘째 단수(單收)의 둔화에 대한 농업투자 및 증산형 기술개발의 확대 셋째 신흥공업국의 식량소비패턴 등이 제기되고 있다. 이외에도 논의되어야 할 주요한 논점으로 첫째 곡물을 포함한 모든 자원의 패러다임이 변화, 둘째 식량 수출규제의 움직임 셋째 BRIC's를 포함한 신흥국의 경제성장이 세계식료수급의 변화 등이 주요한 변수로 작용할 것으로 예측되고 있다 This paper aims to study recurrence possibility of global food crisis in the future. Cheap food has been taken for granted for almost 30 years. From their peak in the 1970s crisis, real food prices steadily declined in the 1980s and 1990s and eventually reached an all-time low in the early 2000s. Rich and poor governments alike therefore saw little need to invest in agricultural production, and reliance on food imports appeared to be a relatively safe and efficient means of achieving national food security. However, as the international prices of major food cereals surged upward from 2006 to 2008 these perceptions quickly collapsed. Furthermore, although food prices are now lower than their 2008 peak, real prices have remained significantly higher in 2009 and 2010 than they were prior to the crisis, and various simulation models predict that real food prices will remain high until at least the end of the next decade.

Sudden onset vertigo is a common complaint in patients who are referred for neurological evaluation. But the entire physical examination and other diagnostic tests may be normal in these patients. Therefore we need more accurate diagnostic tools in the differential diagnosis between the peripheral and the contral vertigo. To evaluate diagnostic effectiveness, we performed Brainstem Auditory Evoked Potentials(BAEP) in the patients with 19 brainstem infarction, 23 peripheral vertigo, 20 vertebrobasilar transient ischemic attack(VB TIA) and analyzed the absolute latency of wave Ⅰ, Ⅲ, Ⅴ and interpeak latency of wave Ⅰ-Ⅲ, Ⅲ-Ⅴ,Ⅰ-Ⅴ compared to normal control data. The results were summerized as follows : 1. There was no significant differences in absolute and interpeak latencies of each BAEP waves between the group of normal control and the group of peripheral vertigo. 2. Among 19 VB TIA patients, prolonged absolute and interpeak latencies of BAEP waves were detected in eleven patients(57.9%) and in nine patients(47.3%), respectively. The abnormal findings were bilaterally in five patients(26.3%) 3. Among 20 brainstem infarction patients, ten patients(50%) showed abnormal BAEP findings, including prolonged interpeak latencies(in three, 15%) and absence of waveform(in seven, 35%). Therefore it is concluded that BAEP could be helpful in differential diagnosis of pathints with peripheral vertigo, V-B TlA, brainstem infarction and other disease of similiar symtomatology.

Objective : This study investigated the relationships of handwriting legibility and perceptual-motor skills, and handwriting speed and perceptual-motor skills. And identified the predictors that most affect the handwriting of preschool children. Methods : Twenty-three typically developing preschool aged children (mean age: 68.61 months, SD=2.04) were selected through the Korean-Denver Developmental Screening Test-2(K-DDST-2). The children were tested with regard to handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Results : First, a significant relationship was not found among handwriting legibility, visual perception, visualmotor integration and fine-motor coordination. Second, a significant relationship was found among handwriting speed, visual perception and fine-motor coordination. Third, stepwise multiple regression analyses showed that general visual perception were significant predictors for handwriting speed. Conclusion : Occupational therapists should evaluate children's visual perception levels utilizing a standardized test, and focus on general visual perception in order to improve handwriting skill(speed). Also, occupational therapists are expected to play an important role in the management and treatment of children's handwriting skills.

In Korea, the industrial structure is, in major, based on the vertical relation between big companies and Small and Medium Enterprises ('SMEs'). Due to this kind of tight relation in supply chain management, the managerial difficulties of the SMEs could not separate from the major strategies of the big companies. In order to stabilize the vertical relation in production, therefore, the more foreseeable and transparent managerial innovation in the big companies side is much more required. In fact, SMEs are critically important in the national economy in that they took the 74.4% of the total labor force and have expanded their role in the national production and value-added activities. However, SMEs face too many difficulties to survive in the big company-oriented structure. Among these difficulties in SMEs, lack of enough fund for the investment and the bottleneck in labor supply require the most outstanding remedies right away. SMEs could not allow enough salary like big companies and thus, could not get the supply of the productive labor force. The problem may lie in the short of the information and poor marketing activities. Among the difficulties faced by the SMEs, the most important factor is the structural discrepancies in the labor market between the demand and supply and thus, this paper is aimed to solve this discrepancies in labor supply.

본 실험은 일반 가정의 식탁에서 흔히 볼 수 있는 산채류 20종에 대해 3주의 gram 양성균(Bacillus subtilis, Lactobacillus casei, Staphylococcus aureus)및 2주의 gram음성균(Klebsie-lla pneumoniae, Shigella sp.)의 성장에 미치는 영향을 조사하였다. 본 실험에 사용한 대부분의 산채류 추출액은 공시균의 성장을 다소 증가시켰다. 특히 표고버섯과 고사리는 그람양성균인 B.subtilis, L.casei, S.aureus균의 취, 더덕과 토란은 B.subtilis, S. aureus균의 성장을 대조군에 비해 2~6배로 크게 증가시켰다. 그러나 그람음성균인 K.pneumoniae와 Shigella sp.에 대해서는 성장을 크게 증가시키는 시료는 없었다. 한편, 죽순은 B.subtilis의, 부지깽이와 민들레는 L.casei의, 팽이버섯과 돌나물 및 두릅은 S. aureus의, 산초, 다래순, 두릅 및 마는 K. pneumoniae의, 죽순, 두릅 및 마는 Shigella sp.의 생육을 다소 저해하는 것으로 나타났으나 항균력은 인정할 수 없었다. This study was carried out to investigate how to influence mountainvegetables, which are commonly available in high mountains in Korea, on bacte-rial growth. Total 20 kinds of mountain vegetables and mushrooms were sampledand after boiling them in water, put water extracts of them into the media prepa-red for the smear of test strains, which were included three of Gram positivestrains (Bacillus subtilis, Lactobacillus casei and Staphylococcus aureus) andtwo of Gram negative strains(Klebsiella pneumoniae and Shigella sp.). The gro-wth of all strains were more or less increased in the media injected with waterextracted samples than that of the control. Especially the growth of B. subtilis,L. casei and S. aureus were increased by the water extracts of Pyogo mushroomand Bracke and the samples from Aster, Deodeok(Codonopsis lanceolata) andTaro were appeared with the increase in growth of B, subtilis and S. aureusby two to six times increase rate than that of control. However, the more growthincrease of K. pneumoniae and Shigella sp. were not found than that of control.There were also observed some of water extracted samples have slight inhibi-tions to the bacterial growth. The growth of strains inhibited by the sampleswere as follows .B. subtilis by water extracts of Bamboo shoot, L. casei bythem of Busiggaengi(Erysimum aurantiacum) and Dandelion, S. aureus by themof Pengi mushroom, Sedum and Fatsia, K. pneumoniae by of them of Chinesepepper, Darae(Actinidia arguta) , Fatsia and Yam and Shigella sp. by of themof Bamboo shoot. Fatsia and Yam. However. these antibiotic effects were soweak that scarecely proved their effects.

신부전이 동반된 당뇨병 환자에서 발생된 침습성 모균증 : 수술과 Liposomal amphotericin B 및 GM-CSF 병합 요법에 의한 성공적인 치험 1예

이원영,오기원,임국희,장재혁,이동건,최정현,강무일,신완식,차봉연,이광우,손호영,강성구 대한화학요법학회 1999 대한화학요법학회지 Vol.17 No.4

저자들은 신부전이 동반된 당뇨병 환자에서 발생된 부비동형 모균증에 대하여 수술과 함께 liposomal amphotericin B 및 GM-CSF의 복합치료를 하여 성공적으로 치료한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Mucormycosis (zygomycosis) primarily affects diabetic or immunocompromised patients and typically progresses rapidly, necessitating surgical excision and antifungal therapy with amphotericin B. Large doses of amphotericin B are needed for cure, but it has the risk of causing significant renal toxicity. The recent development of liposomal amphotericin B allows antifungal therapy to be administered with potentially improved efficacy and reduced nephrotoxicity. We have experienced a case of paranasal mucormycosis successfully treated with surgery, liposomal amphotericin B and GM-CSF. A 59-year-old male suffering from diabetes mellitus for 6 years was admitted with pain at left maxillary area. He was diagnosed as mucormycosis after cytologic exam on the necrotic nasal mucosa, which showed typical hyphae. He have had diabetic nephropathy with macroproteinuria and had rapidly rising serum creatinine levels with the amphotericin B treatment: creatinine levels reverted to basal level with the use of liposomal amphotericin B. Despite surgical excision and continued antifungal therapy, his infection was not effectively controlled. Therefore, GM-CSF was administered additionally to improve phagocytic activity of leukocytes. He was finally cured after receiving a combination of aggressive surgery, liposomal amphotericin B and GM-CSF. To our knowledge, this is the first detailed clinical description of the treatment of mucormycosis with liposomal amphotericin B in Korea.

안원근,주우홍 國立昌原大學校 基礎科學硏究所 1993 基礎科學硏究所論文集 Vol.4 No.-

The DNA base composition of Leucosporidium scottii IFO 9474, L.fellii CBS 7287 and L.lari-marini CBS 7420 was known to be 38.4, 53.2 and 59.6 mol% GC, respectively. The degree of intraspecific relative binding of DNA between L.scottii IFO 9474 and L.scottii type strain CBS 5930 was less than 10%. The degrees of intergeneric relative binding of DNA among L.scottii IFO 9474, Rhodosporidium toruloides, and Mrakia frigida were also less than 10%. Therefore, L.scottii IFO 9474 was genetically different from Rhodosporidium, Leucosporidium and Mrakia.
