Background : The purpose of this study was to determine whether cleansing the perineum and urethral meatus and using midstream urine affect the rate of bacterial contamination of urine specimens, and to determine the optimum urine collection method. We studied 41 asymptomatic healthy nursing school students. Women who were menstruating were not excluded from this study. Method : The first and midstream urine samples were collected during consecutive urinationsby each woman. The first sample was not a clean-catch specimen, and the second one was a clean-catch specimen. Both specimens were studied by urinalysis and bacterial culture with standard methods. Results : 41 women met the study criteria and 39 successfully completed the study. None of the urine cultures were positive. 68.3% of the non clean-catch first urine cultures, 53.7% of the non clean-catch midstream cultures, 33.3% of the first clean-catch urine culteres and 30.8% of the midstream clean-catch urine were found to be contaminated. There was a significant difference in the bacterial contamination rates between the first and midstream urine, and the clean-catch and non clean-catch urine(p=0.035, p =0.001 respectively). On urinalysis, 7.3% of the non clean-catch first urine, 7.3% of the non clean-catch midstream urine, 2.6% of the clean-catch first urine and 2.6% of clean-catch midstream urine were found to be above grade 2. Conclusions : According to our results, the bacterial contamination rate was the lowest in midstream and clean catch urine specimens. Threrfore it is recommended that the midstream clean-catch technique is the standard practice for collecting urine specimens for bacterial culture in women.

A systematic mosquito taxonomic study in Korea was established by Lee in 1971. Since then, many species have been recorded as new to Korea. However, much of this taxonomic information has been distributed in a number of scientific publications. This fork attempts to combine this information into a single document, as well as to synthesize revised taxonomic synonyms of species cccurring in Korea. Four species, Culex vora.x, Culex kangi, Aedes kobayashii and Culiseta kanayamensis listed in our previous paper, are synonyms of Culex kalifaxii, Cutex jackseni, Aedes alehtorowi and Culiseta bergrothi, respectively. Culex annulus is a misidentified species of Culex pseudovishnui. The subspecies Cutes pipiens quinquefassiatus and subgenus Manscnia (Ccquillettidia) were treated as full species and genus respectively in a catalog of the mosquitoes of the world. However, not all current authors agree to those specific and generic treatment. Based on available publications the total number of mosquito species recorded in Korea is now 52 representing 9 genera. Forty-five of these 52 are confirmed species with preserved specimen representation. As collection of specimen continues, there is a possibility that representative of 7 unconfirmed species will be found. 1 hope this paper will provide useful information for entomology workers who are interested in mosquito taxonomy in Korea.

Background: The coronavirus disease 2019 pandemic has been challenging the healthcare service, i.e., the vitalization of the point of care accompanying self-testing in vitro diagnostic medical devices (IVDs). This study aims to suggest priority criteria to classify self-testing IVDs using the analytic hierarchy process technique. Methods: Two dimensions of the characteristics embedded in the IVDs and the diseases to be diagnosed with self-testing IVDs were parallelly considered and independently investigated. In addition, three expert panels consisting of laboratory medical doctors (n=11), clinicians (n=10), and citizens (n=11) who have an interest in the selection of self-testing IVDs were asked to answer to questionnaires. Priorities were derived and compared among each expert panel. Results: First of all, ease of specimen collection (0.241), urgency of the situation (0.224), and simplicity of device operation (0.214) were found to be the most important criteria in light of the functional characteristics of self-testing IVDs. Medical doctors valued the ease of specimen collection, but the citizen's panel valued self-management of the disease more. Second, considering the characteristics of the diseases, the priority criteria were shown in the order of prevalence of diseases (0.421), fatality of disease (0.378), and disease with stigma (0.201). Third, medical doctors responded that self-testing IVDs were more than twice as suitable for non-communicable diseases as compared to communicable diseases (0.688 vs. 0.312), but the citizen's group responded that self-testing IVDs were slightly more suitable for infectious diseases (0.511 vs. 0.489). Conclusion: Our findings suggested that self-testing IVDs could be primarily classified as the items for diagnosis of non-communicable diseases for the purpose of self-management with easy specimen collection and simple operation of devices, taking into account the urgency of the situation as well as prevalence and fatality of the disease.

Successful diagnosis of a disease in food-producing animals depends in many times on proper collection and handling of specimens, as well as careful clinical observation and evaluation of the diseased animals. During the period required to complete the appropriate laboratory tests, an awareness of the potential problems of disease spread to animals at risk and the available palliative treatments is essential. Because most microbial-induced diseases in herds or flocks cannot be effectively treated once the problem is established, management through prevention and control of the disease must be instituted to offer the maximum protection to animals at risk. Thus, the course of disease management for infectious diseases is oftentimes a difficult judgment decision. This paper presents a brief general guide to specimen collection and laboratory methods used for diagnosis of diseases in production animals. (omitted)

An innovative partially precast partially encased composite beam (PPECB) is put forward based on the existing research. In order to study the flexural performance of the new composite beam which has precast part and cast-in-place part, six prefabricated specimens and one cast-in-place specimen are designed with considering the influence of the production method, the steel flange thickness, the concrete strength grade and the stirrup process on the behavior of the composite beam. Through four points loading and test data collection and analysis, the behavior of partially prefabricated specimen is similar to that of cast-in-place specimen, and the casting method, the thickness of the steel flange, the concrete strength grade and the stirrup process have different influence on the crack, yield and peak load bearing capacity of the component. Finally, the calculation theory of plastic bending of partially precast partially encased concrete composite beams is given. The calculation results are in good agreement with the experimental results, which can be used for practical engineering theory guidance. This paper can provide reference value for further research and engineering application.

Purpose: As the medical laboratories in general hospitals have made an efforts on quality management and employee health, they recognized the need of design guideline for clinical laboratory. As laboratories are prohibited to patients, their environments are becoming more congested and deteriorated as time goes by. So, this study investigates the current status of facility and equipment of laboratory medicine focusing on less than three hundred patient bed hospitals, and searches the improving matters. Methods: Questionnaires to technologist captains and field surveys to medical laboratories in korean hospitals have been conducted for the data collection. 18 answers have been analysed statistically by MS Excel program. Results: The result of this study can be summarized into followings. Clinical laboratory functions are all hematology, clinical chemistry, immunology, transfusion and urine microscopy, and except for three including microbiology for infection and bio safety level. Average man power of lab are 12.3 man including lab director and captain. Patient bed number, space area and total specimen numbers are not correlated with each other, but specimen numbers and employee number are correlated with. Work space distances are usually good, but exit distances are not adequate for escape owing to obstacles. Specimen delivery system by courier, test method by automatic analyzer, access floor for exposed plumbing and electricities are more practical. Open lab layed out in the center and lab support layed peripheral in space diagram. Lab space configuration by SD method showed that lab support area and employee support area are dissatisfied. Implications: Specialized hospital and yearly total specimen numbers are related to the space area and organization for laboratory planning and design.

T. Nakai는 1911년 Flora Koreana vol. II에 러시아 식물분류학자인 V. L. Komarov의 1897년 북한 채집 표본을 120여점 인용하였다. Nakai가 언급한 북한의 지명은 약 65개로서 Komarov의 채집지명의 상당 부분에 해당된다. Nakai가 언급한 지명은 러시아발음에 근간을 두고 로마자로 표기하였는데 최근 혹은 과거 지도에서 정확한 채집지명을 확인하기가 매우 어렵다. 본 연구는 Flora Koreana II에 기재된 채집지명을 과거 발표된 러시아와 일본 번역서인 만주식물지와 표본레이블 등의 자료를 근간으로 Nakai가 언급한 원명과, 한자 지명, 현재 지명의 로마자표기, 위도와 경도, 출처의 페이지 등을 도표로 제시하여 정리하였다.

Prevalence rates reported for malaria in pregnancy in Nigeria vary considerably. The accuracy of results of malaria diagnosis is dependent on training, experience, and motivation of the microscopist as well as the laboratory facility available. Results of training programmes on malaria microscopy have shown low levels of sensitivity and specificity of those involved in malaria diagnosis routinely and for research. This study was done to ascertain the true prevalence of malaria in pregnancy in Lagos, South-West Nigeria. A total of 1,084 pregnant women were recruited into this study. Blood smears stained with Giemsa were used for malaria diagnosis by light microscopy. Malaria infection during pregnancy presents mostly as asymptomatic infection. The prevalence of malaria in this population was 7.7% (95% confidence interval; 6.2-9.4%). Factors identified to increase the risk of malaria infection include young maternal age (<20 years), and gravidity (primigravida). In conclusion, this study exposes the over-diagnosis of malaria in pregnancy and the need for training and retraining of laboratory staffs as well as establishing the malaria diagnosis quality assurance programme to ensure the accuracy of malaria microscopy results at all levels.
