위생적인 수확후처리를 통하여 안전한 농산물 생산을 유도하기 위하여 영양부추를 대상으로 수확후 처리시설 모델을 개발하였으며 개발된 수확후 처리시설 설치와 위생교육이 미생물 안전에 미치는 효과를 검증하고자 본 연구를 수행하였다. 이를 위하여 양주지역 영양부추 생산 농가의 수확 후 처리시설 환경과 영양부추에서 위생지표세균(일반세균수, 대장균군, E. coli)과 병원성미생물(Escherichia coli O157:H7, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus)을 조사하였다. 그 결과, 빗, 칼, 도마 등 수확후 처리시설에서 사용하는 작업도구의 일반세균수 오염수준은 수확후 처리시설 설치농가(A, B)에서 수확후 처리시설 비설치농가(C) 보다 1.44~2.33 log CFU / 100$100cm^2$ 정도 낮았다. 특히 도마의 경우 A농가에서 1.00 log CFU / 100$100cm^2$이하, B 농가에서 2.23 log CFU / $100cm^2$인데 반해 C 농가에서는 6.03 log CFU / $100cm^2$로 농가간의 위생 상태에 따라 B. cereus의 오염수준이 차이가 크게 나타났다. 또한 지하수에 침지 한 영양부추에서 침지 전 보다 대장균군이 0.57~1.89 log CFU/g이 증가하였다. E. coli는 영양부추, 침지한 후 지하수, 토양에서 검출되었으며, E. coli O157:H7, Salmonella spp., L. monocytogenes는 검출되지 않았다. 따라서 본 연구의 결과를 통하여 소규모 수확 후 처리시설 설치와 위생교육을 통하여 농가 내 수확후처리 환경의 위생을 개선하는데 효과적이라 판단된다. 이와 더불어 유해미생물에 의한 식중독사고를 사전에 예방하기 위해서는 수확 후에 오염된 유해미생물을 저감화 할 수 있는 세척, 소독 기술의 개발과 도입이 필요할 것으로 사료된다.

This study was performed to investigate the effect of mordants on the dyeability colorfastness to light and to laundering and biological properties of mordanted and natural-dyed cotton and silk substrates. Natural red dyes were extracted from Caesalpinia Sappan L. (Sappan wood) and Rubia Akane Nakai (Madder) by boil water Five different compounds of Al, Cr, Cu, Fe and Sn were used as mordanting agents. The result of this study are sumarized as follows ; 1. In the of the fabrics mordanted and dyed with sappan wood K/S value increases and λmax shifts to the longer wavelength as mordant concentration increases. Color of the fabrics dyed with sappan wood and madder change to redder bluer and lighter after mordanting. 2. As the number of repetition of dyeing-mordnating process increase the color of the dyed fabrics tend to be redder bluer and darker. Mordanted dyes with Al and Sn make chroma increase. The quantity of mordant absorbed in the silk fabric increase as mordant concentration increase. More Fe is absorbed in silk than Cr is. 3. After being exposed to light the fabrics dyed with sappan wood and madder change to less red Fe and Cu mordanting yeild better colorfastness to light than others does. Natural-dyed fabrics exposed to light tend to be faded and whitened in CIELAB chromaticity co-ordinates. So we might trace back the original color of ancient faded fabrics by changes in color of natural dyes. 4. After washing the colors of natural dyes change to more blue, Fe and Cu mordanting give better colorfastness to wash than others do. 5. The soil-burial cotton is more susceptible to mildew and rot than the silk is. Antimicrobial activity of the natural-dyed cotton can be enhanced by Cu and silk can be enhanced by Cu and Cr mordanting respectively.

Objectives: This study was undertaken to analyze Staphylococcus aureus from cultivation environments for agricultural products and to confirm antibiotic resistance and enterotoxin genes for the isolated S. aureus. Methods: A total of 648 samples were collected from apple, peach, ginseng and balloon flower farms. S. aureus was isolated from soil, agricultural water, personal hygiene elements (hands, gloves and clothes) and work utensils (boxes). Results: S. aureus was detected in a total of 25 samples and 72 strains were isolated. The resistance rate of the isolated S. aureus strains was confirmed at 33.3%, with 24 resistant strains among the total of 72. Fourteen different patterns types were found, and three pattern types (NV, OX, VA) were confirmed most frequently. As result of the detection of enterotoxin gene type, four gene types (sea: 1, sed: 4, seg: all isolated S. aureus, sei: all isolated S. aureus) were analyzed among a total of nine types. Conclusions: This study demonstrates that personal hygiene techniques should be properly managed, such as washing and sterilization before or after work, because agricultural contamination by S. aureus frequently developed through improper management.

The purpose of this study was to investigate the rural housewives' recognition and practice on environmental preservation. The subjects of this study were 300 rural housewives living in Chung-buk province. Questionaires were distributed to them during a week from August $25^{th}$ to August $31^{th}$ in 1995. Major findings were as follows: 1. The saved water quite well in washing their faces and the dishes compared with urban housewives, but they did not save water so well in using the lavatory. They used synthetic detergent, one of water pollutants, more often than natural soaps in shampooing and laundering. In addition, they did not use a measuring cup. It resulted in the waste of detergent and aggravation of water pollution. 2. Food waste was disposed of properly, but used batteries were not collected separately. A disposable vinyl bag was more commonly used than a reusable shopping basket. The reason for not using a shopping basket was bothering or uncustomary. Since most of them did not know refillable products of goods with environmental mark, they did not use those. Therefore, housewives should be educated in order to prevent soil pollution. 3. The use of spry-type pesticide and hair treatment, one of air pollutants, was wide-spread among them. They hardly recognized and practiced saving of electric power when they used household electric appliances. 4. The major source of environmental knowledge was mass media like TV of radio. Many of them did not know the practical ways to solve the environmental education program. In conclusion, low level of recognition and practice of rural housewives on environmental preservation indicated that a systematic environmental education program should be developed and implemented.

수확후 시일이 오래 경과되지 않은 금잔디종자의 발아촉진에 관하여 실험한 결과를 요약하면 다음과 같다. (1) 종자를 흡수시켜서 0~$2^{\circ}C$에 2~30일 냉장하는 것은 발아조장효과가 가장 현저하였다. (2) 종자를 농유산에 넣고 유리막대로 잘 교반하며 1분 30쯤 경과한 다음 수세 파종하는것도 발아조장의 효과가 컸다. 그러나 처리가 지나쳐서 종자가 흑별할 저오닥 되면 도리어 해롭다. (3) 잔디종자의 발아는 광선이 투입될 경우에 조장되며 복토는 발아를 감퇴시킨다. (4) 혼사종피마상 및 선부절제도 약간의 발아조장효과가 있는 것 같다. (5) 지벨레린, $NH_4$ $NO_3$, NAA 등의 처리는 발아조장효과가 거의 인정되지 않았다.

회동저수지 집수분지 내 주요 도로변 퇴적물의 중금속 함량은 토양오염 우려기준보다 낮게 나타났다 중금속함량이 높은 지역은 대부분 교통량이 많은 7번 국도이며 , 특히, 커브지점, 우수관, 과속단속 지점, 횡단보도 등에서 높은 함량을 보인다. 도로변 퇴적물 내 입도별 중금속 함량은 세립 입도($63{\mu}m$이하)일수록 높은 값을 보여주고 있으나, 총 함량은 조립 입도의 퇴적물($100{\mu}m$이상)에 의해 결정된다. 이는 우기 시에 유출수에 의해 세립 퇴적물이 주변 수계로 이동된 결과로 해석되며 수영강 및 회동저수지의 수질에 악영향을 미칠 수 있다. 따라서 교통량이 많은 7번 국도와 퇴적물이 쉽게 주변 수계로 유입될 수 있는 한물교와 같은 교량에서 퇴적물의 이동을 조절할 수 있는 적절한 처리시설이 요구된다.

오염물질을 세탁하는 과정에 있어서 보다 효과적으로 오염물질을 제거하고 표백효과를 부여하기 위해서는 기존의 계면활성제만으로는 한계가 있어 추가적으로 표백과정을 거친다. 본 논문에서는 가장 일반적으로 사용되는 표백활성화제인 TAED (tetraacetylethylenediamine)와 신규로 합성한 표백활성화제(OBA, organic bleach activator, decanoyloxyethoxycarbonyloxybenzenesulfonate)를 비교 평가하였다. 합성한 OBA의 안정성을 개선하고자 제오라이트와 폴리옥시에틸렌 글리콜을 사용하여 코팅처리 한 결과 우수한 안정성을 보였다. OBA는 저온($20^{\circ}C$)에서도 우수한 표백효과를 나타냈으며 TAED에 비하여 미생물 분해율이 88%인 물질로 OECD기준(60%) 대비 쉽게 생분해되었다. 세탁과정 중에서 무좀균이나 황색포도상구균에 대해서도 우수한 살균력을 나타내었다.

Objectives : The purpose of this study was to demonstrate the effectiveness and availability of salt pharmacopuncture of Korean sun-dried salt and processing salt on the basis of bibliographical review. Methods : This study was done through a narrative review of related bibliography including medical books, journals, general bibliography, and web sites. Results : 1. Korean sun-dried salt is produced in the ground with soil, tiles, and pottery. Sun-dried, traditional, granulated, bamboo, and grilled salts are all appropriate for medical use. They are composed of a lower level of NaCl and unnecessary substances, and have a higher water and mineral content. 2. The 9~30 g of NaCl included in the physiological saline matches the ratio of a normal human body. However, if the saline is used for water supply, it should be improved because the recommended amount is much lower. 3. Medicine that includes NaCl is applied for lessening the congestion of the nasal cavity, alleviating cornea swelling, or for a lack of water. NaCl can also be used for washing contact lenses as well as cleaning the mucous membrane of the eyes and nose. 4. Salt relieves anger, detoxifies, induces vomiting, builds strong muscles and bones, gives energy, slows aging, and ultimately improves health. 5. Salt treats many diseases including: cardiovascular, hematosis, respirometer, obstetric, musculoskeletal, mineral supplement, eye, teeth and skin issues, etc.. However, salt is not used for treating asthma, cough, or other ailments mainly affecting the vascular system. 6. While NaCl in salt absorbs water and the vascular constriction results in higher blood pressure, the pressure induced from salt is actually a physiologically temporary rise. Rather, salt helps remove oil from the body and its potassium lowers blood pressure. Conclusions : It was suggested that salt pharmacopuncture of Korean sun-dried salt and processing salt should be made available for adjusting the physiological salt concentration and control of the Na side effects, therefore it would be useful in the treatment of diseases.

Based on the results from investigation of behaviour of pulverized fly ashes (PFA) at laboratory and field, the way how to reduce the environmental impacts to geotechnical practices Is considered and described. In order to reduce discharged industrial by-products, it should primarily be emphasized that an effort are made as much as possible not to put into homing. Secondarily, an effort must be made to increase amount of utilization to geotechnical engineering practices. In addition, from an environmental point of view, we should challenge to create innovative materials which are eligible for controlling other wastes and remedying contamination m soils by using industrial byproducts which belong to wastes This Is a new concept in which the polluting materials can be eliminated by making use of wastes. Based on the above-stated concept, the previous and possible utilization of PFA is classified into: (1 ) reclamation, embankment or backfill material, (2) light weight geo-material, (8) soil stabilization/improvement, and (4) environmental material. The reason why PFA, in particular, slurry PFA has been used and will possibly be used more widely is due to the fact that PFA has the advantages : (i) low specific gravity leading to a light weight geomaterial, (ii) high pozzolanic activity enhancing strength, especially due to cement addition, and (iii) spherical shape of particles producing isotropy and then pumpability. As well as the concept of reducing geo-environmental impacts, the present text mainly describes the successful results at laboratory and field which have been obtained by the authors. The most important issue hi application of byproducts including PFA for geotechnical practices is to prevent leakage of polluted substances from sedimentary deposits, ground and earth structures. As one of possible techniques far achieving this purpose, a method of washing off the polluted substances by hot water is described.
