  • 근년에 이르러 waste oil의 문제는 그 어느 때보다도 양이나 종류에 있어서 과거에 볼 수 없었던 만큼 심각한 양상을 나타내고 있다. 1992년도 한해동안 세계적으로 발생된 바 있는 폐윤활유의 양은 약 23,200 mega liter로 추정되고 있으며, 재정제에 의하여 recycle된 oil은 각국에 따라 차이점은 있으나 대략 수요량의 2~3%로서 이들의 합계량은 약 1,890 mega liter로 추정되고 있다. 한편 우리나라 waste oil의 발생량인 경우, 통계가 명확하지는 않지만 1993년도 한해동안 약 75만톤에 이를 것으로 추정되고 있는가 하면, 이 중 특정폐기물로 분류되고 있는 자동차용 폐윤활유에 있어서는 약 18만톤이 발생된 바 있다. 본 기고에서는 각종 폐유 중 특정폐기물인 폐윤활유를 중심으로한 제목건에 대하여 간략하게 기술하기로 하겠다.

  • 제주도는 신생대 제 3기~4기에 형성된 화산섬으로서 수십 차례에 걸친 화산분출에 의해 형성되어 지리적으로 한반도의 최남단에 위치하고 있으며, 우리나라에서 가장 큰 섬이다. 섬 중앙의 한라산을 중심으로 쉴드 화산체를 이루고 있는 제주도는 동서의 길이가 약 74km, 남북의 길이가 약 34km되며 섬 전체 면적이 1,825$\textrm{km}^2$인 타원형의 모양을 하고 있다. 제주도의 중앙부에는 수 차례의 화산활동에 의해 형성된 약 1,950m 높이의 한라산 정상에는 지름이 약 575$\times$400m, 깊이가 100m에 이르는 분화구가 있으며, 돔상의 조면암이 분화구 주변에 관입 되어 있다.(중략)

  • 매년 감귤 가공량은 감귤 생산량의 20%인 약 12만톤을 차지하고 있으며, 이중 가공부산물이 5~7만톤으로 총 가공량의 약 50%가 발생하고 있다. 부산물 중 약 70%는 사료와 한약재로 재이용되고 있으나, 지난해까지 약 30%가 20억원의 처리비용을 들여 바다에 매립 처리되었다. 그러나 올해부터 런던 협약에 의해 해양투기가 금지되었고 2014년 이후에는 육상폐기물의 해양투기가 전면 금지됨에 따라 시급한 대책이 필요한 실정이다. 이에 국립원예특작과학원에서는 감귤가공부산물을 이용해 기능성 식음료, 바이오겔 등 다양한 제품을 개발했다.

  • Research situation and recent research activities of the RDA of Korea were reviewed and summarized for rice nurserybed. Sixty five percent of total 784 weed research items were carried out as rice research while only 6 percent was belonged to nurserybed within rice research. The floristic composition based on the degree of dominance significantly affected by herbicide properties, type of nurserybed and seeding itself. Herbicidal phytotoxicity of currently used several herbicides was greatly dependent upon the covering, absorption, germination, and irrigation regimes. The new safening agent "CGA 123 407" (4,6-dichloro-2-phenyl-pyrimidine) permited the safe application of pretilachlor (2-chloro-2',6-diethyl-N-(2-propoxyethyl) acetanilide) as a pre-emergence herbicide without reducing herbicidal efficacy. Several new herbicides, pyrazolate (4-(2,4-dichlorobenzoyl)-1,3-dimethylpyrazol-5-yl-p-toluenesulphonate), SL-49 (1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-phenacyloxy-pyrazole) MY-93 (S(1-methyl-1-phenethyl)-piperidine-1-carbathioate) and DPX-84 ((methyl 2- ((4,6-dimethoxypyrimidin-2-yl) amino-carbonyl) aminosulfonylmethyl)) benzolate)) performed satisfactorily in terms of safety and herbicidal efficacy for both surface covered and surface pressed nurserybed after herbicide application and thus expected very significant contributions not only for all kind of nurserybeds but also for direct seeding.

  • Objectives: This study was conducted to investigate the treatment status and its related factors of the rural hypertensives. Methods: A questionnaire survey was performed to 618 rural hypertensives during September, 2002. Results: The proportion of those who were compliant to the antihypertensive medication was 68.9%. The compliance rate to the antihypertensive medication was significantly related with sex and economic status(p<0.05). That is, if they were female, higher economic level, the regular antihypertensive medication rate was higher. The regular antihypertensive medication rate was higher when they had higher knowledge for hypertension, higher severity for hypertension of him or her(p<0.01). And the compliance rate to the antihypertensive medication was significantly related with hypertensives' own explanatory model for hypertension(p<0.01). The rate of drug use except antihypertensives was 12.5%. The rate of drug use except antihypertensives was higher when they experienced side effects of antihypertensive drug and when they had irregular medication for antihypertensive drug(p<0.01). The rate of medical equipment use was 18.9%. The utilization rate of medical equipment such as jade mat, germanium material was significantly related with age, experience of side effects of antihypertensive drug, medication status for antihypertensive drug(p<0.05). The rate of folk therapy use was 16.2%. The rate of folk therapy use was higher when they had no family, when they had knowledge about hypertension on the average, when they had hypertension over 10 years(p<0.05), and when they experienced side effects of antihypertensive drug and when they had irregular medication for antihypertensive drug(p<0.01). The rates of drug use except antihypertensives, medical equipment use, and folk therapy were significantly related with hypertensives' own explanatory model for hypertension(p<0.05). Conclusions: On consideration of above findings, it would be essential to provide knowledge about hypertension and its treatment, and severity of hypertension complications through health education.

  • A study was done to investigate characteristics of the land and sea breeze over Cheju island on the basis of surface meteorological data collected from 1977 to 1986. The results are summarized as follows: The frequency of the land and sea breze was highest in August followed by September, October, May and November in descending order. This indicates that the frequency of the land and sea breeze is higher in fall than in spring, and lowest in winter. The sea breeze began much earlier than any other regions of Korea all the year round, and it began about 30 minutes earlier and ended one hour later in the northern coast than in the southern coast of Cheju island. Meanwhile, the land breeze began about one hour earlier in the southern coast than in the northern coast and ended almost at the same time in both coasts. The annual mean duration of the sea breeze was about one hour longer in the northern coast than in the southern coast, but the land breeze showed an opposite trend. The duration of the sea breeze was longer in summer than in winter and again the land breeze was opposite. Transition period from the sea to the land breeze was relatively long in summer and shout in winter, but transition period from the land to the sea breeze was not different between seasons. The time for a maximum velocity of the sea breeze came earlier in the southern coast than in the northern coast, but that of the land breeze came almost at the same time in both coasts with no seasonal variations. Monthly mean maximum velocity of the sea breeze was greater than that of the land breeze.

  • We simulated the current limiting characteristics of resistive and inductive SFCLs with 100 ${\omega}$ of impedances for a single and double line-to-ground faults in the 154 kV grid between two substations nearby Seoul. The transient current at the faults includes not. only high AC current up to 44 kA but also significant DC component as high as 4 kA. The DC current is greater and lasts longer for the double line-to-ground fault than for the single line-to-ground fault. The inductive SFCL limited the fault current more effectively than the resistive one. The DC component, however, was greater and diminishes slower for the inductive SFCL than for the resistive one.

  • The experiments were conducted to evaluate safening effect of fenclorim (CGA 123'407, 4,6-dichloro-2-phenyl pyrimidine) against injuries of pretilachlor, butachlor, and benthiocarb in direct-seeded rice under flooded conditions. Pretilachlor and butachlor and benthiocarb reduced crop standing and inhibited growth of rice plants. However, premixture application of pretilachlor, butachlor or benthiocarb with fenclorim at 10-30 g ai/10a greatly reduced rice injury caused by the application of each herbicide alone and thus increased crop standing plant height and dry weight of rice plants compared to herbicide treatments alone.

  • The experiment was crried out to evaluated the herbicidal properties of bensulfuron methyl [methyl 2-[[[[[(4, 6-dimethoxy pyrimidine-2yl) amino] carbonyl] amino] sulfonyl] methyl] benzoate]. No phytotoxicity was observed when bensulfuron methyl was applied at 3 and 6 g a.i./ 10a while the application rate 12 g a.i./10a slightly retared the growth of rice. The phytotoxicity decreased as the application time was delayed. The effect of application rate, leaching grade, transplanting depth, soil type and temperature on crop injury was little. Japonica variety (Dong-Jin) was more sensitive to bensulfuron methyl than indica X japonica variety (Sam-Kang). Bensulfuron methyl controlled effectively perennial weeds such as Sagittaria pygmaea Miq., Potamogeton diatinctus A. Benn., Cyperus serotinus Rottb., Sagittaria trifolia L., Eleocharis kuroguwai Ohwi. including most annual weeds except Echinochloa crus galli P. Beauv. The effect slightly decreased with lowering the temperature increasing the leaching grade. Application time and soil type employed did not affect the weeding effect.
