Swallowing disorders that can affect nutrient intakes and quality of life are commonly shown among the elderly as well as patients with neurogenic disorder. This study verifies the reliability and validity of the Swallowing Disturbance Questionnaire (SDQ), a subjective swallowing disability assessment tool, modified for Koreans' eating habit and cultural sentiment, against 105 stroke patients, in order to help identify early swallowing problems of the elderly. Reliability of internal consistency in the Korean version of SDQ is .601, test-retest reliability is .97, and concurrent validity is .956. Based on 8 points of cut-off score, 46.8% of sensitivity and 81.6% of specificity. Comparing the results of video fluoroscopic study (VFSS), an objective swallowing disorder test with those of Korean version of SDQ, negative predictive value (NPV) and positive predictive value (PPV) was shown as 81% and 53%. The Korean version of SDQ is expected to be a useful testing tool to discriminate swallowing disorders in stroke patients. It has great clinical significance in that swallowing difficulties shown by subjects can be sorted out to request a diagnostic assessment before clinical evaluation by a rehabilitation therapist or ruling out unnecessary exposure to additional tests by accurately identifying stroke patients without swallowing problems.

복무적합도 검사는 정신질환이나 사고가능성이 있는 병사를 감별하고, 입대 후 적응문제로 조기 전역할 수 있는 집단을 예측하는 신인성검사 중 하나로, 현재 군에서 징병 및 입영단계에 실시하는 인성검사이다. 이는 전체 검사대상자를 상대로 정신과적 문제 식별을 위한 개별면담이 불가능하기 때문에 위 검사를 통해 대상자를 효율적으로 선별하기 위함이다. 본 연구는 데이터 마이닝을 통해 복무적합도 검사의 판정을 예측 할 수 있을지 확인하고자 하였다. 이를 위해 데이터 마이닝의 기법 중 회귀분석의 로지스틱 회귀분석 기법이 복무적합도검사 판정에 우수한 성능을 보임을 확인하였고, 로지스틱 회귀분석의 추정된 회귀계수를 이용하여 만든 반응확률에 대한 예측 모형식은 높은 정분류율을 보였고 평가 결과 통계적으로 의미가 있음을 증명하였다. 따라서 본 연구 결과를 활용하면 소수의 문항으로 복무적합도 검사 이전의 선별용 검사 개발이나 자가 진단용 검사 개발로 활용이 가능 할 것으로 기대한다.

In this study, an online seed potato sorting system using a visible and near infrared (40 1100 nm) transmittance spectral technique and statistical model was evaluated for the nondestructive determination of infected and sound seed potatoes. Seed potatoes that had been artificially infected with Pectobacterium atrosepticum, which is known to cause a soil borne disease infection, were prepared for the experiments. After acquiring transmittance spectra from sound and infected seed potatoes, a determination algorithm for detecting infected seed potatoes was developed using the partial least square discriminant analysis method. The coefficient of determination($R^2_p$) of the prediction model was 0.943, and the classification accuracy was above 99% (n = 80) for discriminating diseased seed potatoes from sound ones. This online sorting system has good potential for developing a technique to detect agricultural products that are infected and contaminated by pathogens.

Purpose : To evaluate the diagnostic value of dipstick urinalysis($Multistix^{(R)}$) as a screening test for urinary tract infection(UTI) in acute febrile children. Methods : We compared dipstick uinalysis (leukocyte estease(LE) and nitrite) with microscopic urinalysis (WBC and bacteria) and urine culture in 80 children with UTI and 605 children without UTI, who were admitted due to acute fever at EWHA Womans University Hospital between Oct. 1994 and Feb. 1996. Results : 1) In dipstick urinalysis, LE and nitrite were positive in 38.7%, and 13.8% of 80 children with UTI and in 2.1%. and 1.2% of 605 children without UTI. 2) In microscopic urinalysis, WBC and bacteria were positive in 31.2%, and 17.5% of 80 children with UTI and in 4.1%, and 0.6% of 605 children without UTI. 3) Positive rate of LE on dipstick urinalysis was 38.7%, which was significantly higher than 31.5% of WBC on microscopic urinalysis (P<0.05). Positive rate of nitrite was not significantly different to that of bacteria. 4) Sensitivity, specificity, positive predictive value, negative predictive value of dipstick urinalysis were 43.7%, 98.3%, 63.6%, 92.9% which were not significant different to 40.0%, 99.0%, 54.0%, 92.3% of microscopic urinalysis. The sensitivity of combined dipstick and microscopic urinalysis were still low(50%). 5) Additional positive rate of microscopic urinalysis to negative dipstick urinalysis was 6.3%(5/80) in 80 children with UTI. Conclusion : The sensitivity of dipstick urinalysis was low and additional value of microscopic urinalysis was minimal in febrile UTI. So urine culture is mandatory in acute febrile children even though dipstick and microscopic urinalysis are negative.

Objective : The purpose of this study was to develop a Yonsei dual task cognitive screening test (Y-DuCog) for the elderly. Methods : The reliability and validity test of Y-DuCog (Yonsei Dual Task Cognitive Screening Test) was developed by 229 elderly people aged over 60 years from community organizations at Gyeonggi-do and Chungcheong-do from May 2019 to August 2019. In addition, the criteria for classifying elderly with cognitive impairment were presented. Results : The correlation analysis between MMSE-K, MoCA-K and Y-DuCog were a correlation between the DTE and CRR of Y-DuCog. As a result of internal consistency, Cronbach's-α values of DTE and CRR showed .848 (p<.01) and .916 (p<.01), respectively. The test-retest reliability was high. The screening point showed 88.7% sensitivity and 83.5% specificity at 31.76 seconds in total DTE, and 84.5% sensitivity and 76.6% specificity at 0.38 in total dual-task CRR. Conclusion : This study verified the reliability and validity of Y-DuCog. It was found that the level of education was not a barrier to the undertaking of this test. Furthermore, the test could be performed easily and quickly. It is also expected to be used to evaluate the effectiveness of cognitive function assessment and intervention methods in the elderly.

Cytotechnologists evaluate and analyze disorders of cells that constitute the human body, and are involved in the primary assessment of diverse diseases, including cancer. However, the employment conditions and workload of cytotechnologists are poorly understood. This study was undertaken to provide basic data for establishing the criteria for quality control certification factors based on the scope of effective task performance of cytotechnologists, and to provide results of their workload analysis according to the type of medical institution. The study was conducted by enrolling certified cytotechnologists working at various nationwide medical institutions. Our analysis revealed that 178 personnel (72.7%) were involved in primary screening of samples. On an average, the daily number of primary screening of samples performed per cytotechnologist (76 respondents) was determined to be 75.4 chapters (16.8 chapters/hours) at the university hospital level, 72.4 chapters (18.6 chapters/hours) at the general hospital level, and 231 chapters (32.6 chapters/hours) at professional trust institutions. Our results indicate the necessity to establish a consultant with the Korean Cell Pathology Association, to enable finding solutions to solve existing issues by establishing accurate standard guidelines for assessing cell screening.

COVID-19, which occurred in 2019, has a strong contagious power, has serious symptoms of infection and after-effects, and death in severe cases depending on the underlying disease and symptoms. As COVID-19 is highly contagious, in Korea, screening clinics have been set up across the country to determine whether or not to be positive for COVID-19 and isolate the infected to prevent the spread of COVID-19. However, there are cases where COVID-19 test applicants flock to screening clinics and cannot receive tests due to longer waiting times, and there is a risk that secondary infections may occur in the atmosphere. In this study, the reservation and notification system can be applied from the existing screening care system to solve spatial constraints, reducing waiting time with screening appointments, and solving population bottlenecks to screening clinics. Taking the COVID-19 pandemic as an experience, we propose a system that can present directions in future pandemic situations. To process real-time data, we use Google's Firebase to use Realtime Database in the cloud environment. Because a real-time database is used, users can check the status of screening clinics in real time through the app, make reservations, and receive notifications about test reservations.

Lutheran a antigen ($Lu^a$) is detected in 6 to 8% of Caucasians and Africans. In Korean and other Asian populations, it is very rare or nearly absent. Therefore, although $Lu^a$ has a considerable immunizing capacity, sensitization to $Lu^a$ is a rare event. Here we report on a rare case of anti-$Lu^a$ in a 70 year-old female patient with Lu (a-/b+) phenotype and review the relevant literature. Due to the paucity of $Lu^a$ positive panel cells in antibody screening and identification tests, detection of this rare antibody to $Lu^a$ antigen is not feasible. Therefore, we should keep in mind the possibility of the misleading false negative result in detection of antibody to this low incidence antigen.

Patients with type 2 diabetes mellitus can complain of abnormal sensation and pain which derived from the peripheral nerve damage. Various words used to be describe abnormal sense and pain, such as sharp, hot, dull, cold, sensitive, and itch. To diagnose diabetic peripheral neuropathy, several screening instruments (Neuropathic Pain Scale, NPS; Michigan Neuropathy Screening Instruments, MNSI) and electrophysiological study can be used. In this study, we aim to analyze and compare the clinical and electrophysiological characteristics of 11 patients with diabetes mellitus and abnormal sense/pain (Disease Group, DG) and 10 patients with diabetes mellitus and normal sense (Control Group, CG). In addition, we aim to reveal correlation between NPS subscore and electrophysiological parameters. As a result, the scores of NPS and MNSI in DG were significantly higher. In nerve conduction study, median motor nerve and peroneal nerve showed significant functional change. Also, median motor nerve, posterior tibial nerve and sural nerve showed negative correlation as NPS subscore increased. These results mean increased pain can be associated with abnormal nerve function. It needs to be further explored for larger size of subjects to get confirmative results.
