21세기 초, 기침환자를 맞은 의사는 먼저 환자의 목구멍에 면봉을 넣은 다음 면봉에 묻은 무수한 미생물의 유전자를 바이오칩으로 점검한다. 5~6분 뒤 바이오칩은 기침의 '범인'을 밝히고 이 미생물이 특정한 항생제에 저항하는 유전자를 갖고 있는가의 여부도 가려낸다. 그래서 의사는 환자 개개인에게 정확하게 들어맞는 약을 처방할 수 있다.

Purpose: The present study was conducted to investigate whether the elution of the dyes from the circle contact lenses existed or not when rubbed with cotton swab. Methods: The change of lens surface was observed by scanning electron microscope when a total of seven kinds of circle contact lens were rubbed with cotton swab, and the dye elution was further compared when the lenses were soaked in multi-purpose solution in $20^{\circ}C$ and $36.5^{\circ}C$ for a week. Results: Five of a total of 7 circle contact lenses showed the dye elution from the front or the back surface of the lens when rubbed with cotton swabs, and existence of dye elution was varied depending on the type of contact lenses and different at the front and back surface even in the same lens. The tear-off of the pigmented portion by the rubbing was found through scanning electron microscopic observation when the dye elution existed. However, the dye was not eluted when the circle contact lenses was soaked in a multi-purpose solution in $20^{\circ}C$ or $36.5^{\circ}C$ for a week. Ingredient of colorant was not provided by the manufacturers in more than 50% of the circle contact lenses investigated for this study and the basic information such as the pigmentation method was provided inappropriately. Conclusions: In this study, the result was the dye elution from circle contact lenses was obtained when a physical force is applied thus, it may appear to contribute the development of circle contact lenses and safety of lens wear.

The face of the Seated Stone Buddha ^{Korean Treasure No.84} of Sinboksa Templesite in Gangneung was contaminated with a glossy resin, spoiling its beauty. The contaminants covered the face, the forehead of the urna, to the bottom of the jaw. FT-IR analysis on a sample of the contaminants identified the substance as cyanoacrylate instant adhesive, which can normally be melted with acetone and removed with a swab. However, given that the surface of the statue was severely weathered from prolonged open-air exposure, alternative removal procedures were considered, to minimize the possibility of physical damage. After research, two removal procedures were utilized: one procedure involving poultices, which had been used to remove graffiti from the Samjeondobi Stele, and one procedure involving steam sterilization, which has been used to remove resin from pottery and porcelain. When both the poultices and steam sterilization were applied together, the resin was removed within twenty-four hours, without physical work using a swab.

This study investigated the effects of using a pollen suspension for artificial pollination on the labor costs, fruit set, and fruit quality attributes of 'Fuji' apples. The pollen germination rate was 20% in a 20% fructose solution after 6 hours, and the pollen remained stable for 6 hours in the same solution. The king fruit per flower cluster exhibited a normal fruit set, regardless of the treatment. Plus, none of the artificial pollination applications affected the fruit length/diameter ratio, flesh firmness, soluble solids concentration, or titratable acidity in the harvested 'Fuji' apple fruits. However, the labor savings were significantly higher with the pollen suspension treatment when compared with the cotton swab or love-touch. Therefore, the labor cost was four-fold less in use of pollen suspension than in use of cotton swab for artificial pollination.

Swabs are useful and common sampling tools in various research fields, such as medicine, ecology, biotechnology, forensic medicine, and pollutant monitoring systems. Collection reagents are one of the essential components in sampling. It is important to develop a sample collection kit and designate an appropriate storage temperature because samples need to be stored for a long time. The purpose of this study was to identify the effects of three collection reagents and three storage temperatures on the recovery of living bacteria without media. We selected Escherichia coli and Staphylococcus aureus as representative environmental bacteria. Distilled water (DW), phosphate buffered saline (PBS), and Tris-EDTA (TE) buffer were used as collection reagents and stored at 22℃, 4℃, and -70℃ after sampling. The results of using each collection reagent and storage temperature on the bacteria were compared using relative light units (RLU) and the number of colony forming units (CFU). When using -70℃ storage temperature and the TE buffer, the number of living bacteria and the RLU values remained constant. It is therefore recommended that the sample be stored at -70℃ immediately after collection and a TE buffer solution be used as the collection reagent.

일반적인 치료에 반응을 나타내지 않는 호흡곤란증에 걸린 4년령의 Shepherd개에서 피부, 눈, 림프절의 병변을 동반한 치명적인 파종성 크립토콕스병이 진단되었다. 세포학적검사에 의해 난원형 내지 구형이고, 두꺼운 협막을 갖고 있는, 형태학적으로 Cryptococcus neoformans와 일치하는 효모균이 증명되었다. 이 병원체는 혈액, 오줌, 콧물, 견갑전림프절 흡인물, 피부생검 시료, 피부 면봉 시료 등을 25$\circ $C의 Pal씨 배지에 접종하여 용이하게 분리되었다 배양물을 PHOL염색액으로 염색하여 현미경으로 검사한 결과 얇은 막에 싸인 발아를 나타내거나. 나타내지 않는 구형 내지 난원형의 효모균이 증명되었다. 이 개는 ketaconazole 로 치료를 시작 한 후 6일만에 폐사하였다. 공기, 흙, 비둘기 배설물, 톱밥 등을 Pal씨 배지에 접종하여 C.neoformans가 배양됨으로써 역학적으로 환경이 병원소 역할을 한 것으로 판단되었다. 환축과 환경으로부터 분리된 균주는 세밀한 동정결과 neoformans (serotype AD)에 속하며, Filobasidiella neoformans "alpha" mating type을 나타내었다. 이 연구결과, Pal씨 배지가 크립토콕스병의 조기진단과 역학적 조사에 훌륭한 감별배지라는 것이 입증되었다. 개량된 Pal씨 배지는 C. neoformans의 genetic crossing을 판단하는데 성공적으로 사용할 수 있었다.

Purpose: The purpose of this study was to evaluate the transmission of candida in denture by dental polishing lathe. Materials and Methods: Maxillary complete dentures made from the same model were infected with Candida albicans. Polishing wheels were keep in various chlorhexidine solution and distilled water for an hour. The infected dentures were polished by prepared dental polishing lathe with sterile pumice and distilled water. And then sterile maxillary complete dentures were polished with same method. Polishing surface was wiped with a cotton swab and the sample was regrown for checking Candida albicans. Results: All polishing wheel with chlorhexidine resist fungal infection. But the polishing wheel with distilled water is infected with Candida albicans. Conclusion: A chlorhexidine is highly efficient in fungal infection prevention on dental polishing lathe.

The gross alpha analysis of nasal smear samples for the radiation emergency and the additional follow-up steps were established. Cotton swab sticks using in local hospitals for nasal smear in Korea were used for the verification. The measurement results of standard samples spiked with certified reference source were well agreed within ${\pm}20%$ compared with reference values. The clearance ratio of smear samples conducted with wet smear condition showed higher value. To eliminate the quenching effect of liquid scintillation samples, dry of smear samples should be followed up before counting samples. Based on the measurement results, medical decision levels and internal dose assessment were established for the victims in the beginning of radiation emergency.

This study, by selecting 3 kinds(Polish T, H, C) of metal polish being frequently used for silver archival objects treatment at present, a polish having excellent conservative property that minimizes damage of silver surface while effectively removing its yellow discolored layer by each using tool was intended to be discovered by comparing performance of tarnish inhibitor, corrosion inhibitor contained in each polish. As a result of analysis, it was confirmed that specimen that was cleaned with cotton swab and lint-free wipe by using Polish C provides not only uniformed surface expression and minimum damage but also removal function of corrosion layer. In addition, even though tarnish inhibition film should be formed after polish treatment, discolored phenomenon is unable to be prevented but among those polishes, Polish C was represented to be most stable against UV and yellowing and it showed relatively better features than that of Polish H and T in terms of hydrophobic, dispersive property. Through this, it is confirmed that Polish C would show the most excellent performance among polishes being used for conserving silver archival objects.
