요검사는 물리적 성상 검사, 화학적 검사, 현미경 검사 세 가지가 있다. 이 중에서 화학적 요검사는 일반인이 쉽게 접근하는 방법으로 요검사지의 화학반응을 눈으로 표준비색표와 비교하거나 휴대용 요검사기를 별도로 구매하여 검사를 진행한다. 현재는 스마트폰의 보급이 대중화되어 스마트폰을 활용한 요검사 서비스 연구가 높아지고 있다. 요검사 스크리닝 애플리케이션은 스마트폰을 활용한 요검사 서비스 중 하나이다. 그러나 요검사 스크리닝 애플리케이션으로 촬영한 요검사 패드 RGB 값은 조명영향으로 인해 큰 편차가 발생한다. 요검사 패드 RGB 값의 편차는 요검사 판별의 정확도를 떨어뜨린다. 따라서 본 논문에서는 스마트폰 기반 요검사 스크리닝 애플리케이션으로 촬영한 요검사지를 검사 항목별 요검사 패드로 분류한 후 CNN을 통해 요검사 패드 이미지 판별의 정확도를 높인다. 요검사지는 다양한 배경에서 촬영하여 CNN 이미지를 생성하였으며 ResNet-50 CNN 모델을 사용하여 요검사 판별을 분석하였다.

Routine urinalysis is a simple, economical, and useful test that facilitates the detection of urinary system diseases and monitoring of renal disease progression. It consists of 4 parts of specimen evaluation, gross examination, a dipstick urinalysis, and a sediment microscopic urinalysis. Urine specimens should first be evaluated in terms of acceptability, and thereafter, the gross appearance is examined for color, turbidity, and odor. In particular, a dipstick urinalysis is an easy and rapid test that provides information on the multiple physicochemical properties of the urine sample. Moreover, although a sediment microscopic urinalysis is time-consuming, it provides information on the cells, microorganisms, casts, and crystals. In the present report, the clinical significance of the routine urinalysis and the problems concerning interpretation are summarized.

This study focuses on the contents about the Urinalysis which is the most representative one of the Tibetan medicine. Also, this study compares it with the Urinalysis of Traditional Korean medicine. This study focuses on the simple history, the theoretical system, the diagnosis and the urinalysis mainly based on the documents related to the Tibetan medicine. Also, through the comparison with the contents of textbook of Traditional Korean Medicine and the urinalysis shown in the Dongeuibogam(東醫寶鑑) which is the representative Korean medical book, the difference between Tibetan Medicine and Traditional Korean Medicine will be observed. The contents related about the urinalysis of the Tibetan medicine are more specific than those of Traditional Korean Medicine. By observing the color, scent, vapor and sediment of one's urine together with periodic changes more thoroughly, it is possible to find out the cause of a certain disease. However, Traditional Korean Medicine examines the medical conditions mainly based on the state of discharge and fever, showing a clear difference. The Tibetan medicine has an extremely specific type of urinalysis in comparison with that of Traditional Korean Medicine. It is the only characteristic of the Tibet medicine, which cannot be found in any other traditional medicine. By applying the viewpoint of the doctor who diagnoses the patient by measuring his or her pulse, it is possible to make the diagnosing process more specific and accurate. It is expected that the follow-up study will be continuously executed with the introduction of the system for the urinalysis of the Tibetan medicine to Traditional Korean medicine.

Urethral obstruction is a life-threatening feline lower urinary tract disease (FLUTD). The rate of recurring urethral obstruction was 14.8-58.1% after the first occurrence. Ultrasonographic findings associated with reobstruction had been rarely reported although ultrasonography was a valuable technique for diagnosing urinary bladder calculi and distinguishing different FLUTD causes. This retrospective study aims to describe the ultrasonographic findings, urinalysis, and serum chemistry profile in cats with FLUTD and determine the associations of reobstruction with ultrasonographic findings, urinalysis, and serum chemistry profile. The present study included 141 cats that were followed up for more than 1 year. The ultrasonographic criteria included the presence of cystolithiasis, urine echogenicity, sediment, suspended linear strand, pericystic effusion, hyperechoic pericystic fat, ureteral dilation, pyelectasia, and perirenal effusion. The urinalysis criteria included hematuria, urine-specific gravity, pH, sediment, and proteinuria. The most common ultrasonographic findings in cats with FLUTD were echogenic urine and sediment. However, this study did not find an association between reobstruction and ultrasonographic findings, urinalysis, and serum chemistry profiles. Thus, an ultrasonographic examination may be insufficient to predict the risk of reobstruction although it is a useful modality for diagnosing FLUTD and making treatment direction.

Improving validity and reliability is the important components of clinical laboratory tests. And the quality control of the test should be started with the accurate collection of specimen. Urinalysis is one of the useful and common tests in diseases diagnosis and determining the process of medical treatment. Since urinalysis is requested routinely in hospital setting, the importance of the quality control for urine specimen is often ignored. To improve the validity of urinalysis, a clinical trial was done on the method of collecting urine specimen. The result was as follows : 1. The rate of presumtive UTI(urinary tract infection) was decreased in 21.6% with experiment method for collecting urine specimen. 2. The rate of presumtive UTI in female patients was decreased in 43.2% with the experiment method. 3. The rate of negative urine culture was decreased in 6.6% with the experiment method.

The spectroscopic characteristic of 9 items in the urinalysis strip are measured to develop the urine analysis system. From experimental results, we determined the wavelength range which could accurately distinguish the degrees of 9 test items. Simulation is performed to distinguish the primary color reaction in the urinalysis strips using reflectance of urine strips, luminous intensity of LEDs, and spectral sensitivity of photodiodes. The simulation results agree well with experimental results by using UV-Visible spectrophotometer.

To evaluate the effects on health by exposure to mixed organic solvents, the author analyzed some labortory findings of blood (hemoglobin, hematocrit RBC, WBC, SGOT, SGPT) and urine (protein, blood, sugar) that were obtained from 722 workers (male:446, female:276) who worked in plywood, painting and shoes factories in Pusan area from January to December, 1990. The result were as follows ; 1. The mean values of each hematologic findings were all within normal limit but there were significant differences at hematocrit, RBC, WBC, SGOT in male and at WBC, SGPT in female at the comparison of the mean values and the distribution according to the normal criteria by type of work. 2. There were no differences in urinalysis(protein, blood, sugar) by type of work. 3. In stepwise multiple regression, analysis of hematologic findings on age, working duration and type of work, regression coefficients on age and type of work were relatively high in male and female sub1, respectively. As a result of this study, it is considered that the measurement of WBC with morphology is significant in hematologic findings and instead of spot urine and urinstix, 24 hours urine and quantitative analysis is required in urinalysis in screening test for healthy status of workers who deal with the organic solvents.

The purpose of this study is to find out the difference in circadian rhythm and level of fatigue between ER and General Ward Nurse. This study was done through analyzing body temperature, heart rate and major electrolytes such as $Na^+$ and $K^+$ concentration on urinalysis, which are related to factors of circadian rhythm and level of fatigue. The subjects, 17 nurses from Emergency Room and 25 nurses from general ward, were selected from a General Hospital in Taegu City on August 8 to 23, 1998. And the data were analyzed by proportion, t-test, chi-square and Pearson's Correlation, ANCOVA, using SAS program. The results of this study were shown as follows: First, The difference of Maximal and minimal heart rate was significant between ER group and general ward group. However, body temperature difference wasn't notable. Second, Urine $Na^+$ concentration on urinalysis was lower and $K^+$ concentration on urinalysis was higher in ER group than general ward group significantly. Third, Fatigue level was higher in ER group than general ward group significantly. Fourth, through urine concentration, significant relations in circadian rhythm of ER nurse group and general ward group and their fatigue level were found. Urine $Na^+$ concentration on urinalysis of ER nurse was significant related with their fatigue level. In conclusion, the effect of fatigue on circadian rhythm is greater in ER group than general ward group during night shift. This study could be a help in improvement of nurse's health and understanding the effect of fatigue on health.
