Deglutition inspection has been the gold standard for inspection of dysphagia using a penetration device of the division of radiology to date. However, inspection using an endoscope has facilitated diagnosis of dysphagia in recent days. In this study, we compared the results of VFSS alone with those of VFSS combined with FEES to determine if the detection rate of penetration, aspiration, and pharyngeal residue increased. This study evaluated at 130 persons who underwent both VFSS and FEES from December 2013 through March 2014, and used VFSS (FELAVISION, SHIMADZU) and FESS (EVIU LUCERA CV-260SL, OLYMPUS) as devices. After preparing barium diluted solution, yogurt that diluted barium and rice that diluted barium in 2.5 ml, 5 ml, 10 ml by modifying Logemann's protocol in part, and having subjects take the solution, this study confirmed pharyngeal residue, penetration, aspiration etc. VFFS and FEES using full HD video revealed aspiration in 36 of the 130 patients in both inspections. Additionally, aspiration was discovered in 36 patients upon VFFS, but in 41 upon FESS. Although FEES was more sensitive at diagnosing dysphagia, the two inspection methods are complementary, so diagnostic value will be greatly improved when the endoscope operating method and accurate fluoroscopic inspection are combined.

We did the comparison research about three different methods of measuring horizontal phoria and vertical phoria which are Von Graefe test, Maddox Rod test and polarizing lens test. The inspection was don with the subjective method of refraction about normal 63 subjects aged from 20 to 28 years old. The analysis of date resulted in as follows : 1. Using Von Graefe Horizontal phoria Measurement, they were measured 5% for orthpharia, 51% for exophoria and 44% for esophoria. 2. Using Von Graefe vertical phoria Measurement, they were measured 68% for orthphoria, 20% for left hypophoria against the right and 12% for left hyperphoria against the right. 3. Using Maddox Rod Horizontal phoria Measurement, they were measured 7% for orthphoria, 49% for exophoria and 44% for esophoria. 4. Using Maddox Rod vertical phoria Measurement, they were measured 70% for orthphoria, 19% for left hypophoria against the right and 11% for left hyperphoria against the right. 5. Using Polarizing Horizontal phoria Measurement, they were measured 10% for orthphoria, 49% for exophoria and 41% for esophoria. 6. Using Polarizing vertical phoria Measurement, they were measured 92% for orthpharia, 5% for left hypophoria against the right and 3% for left hyperphoria against the right.

에이즈 검사는 크게 항원 검사와 항체 검사로 나눌 수 있다. 에이즈 바이러스(HIV)가 항원이며 이것이 우리 몸에 침입하였을 때 이 항원의 모양에 맞게 항체가 형성된다. 항원검사는 보조검사이고 항체검사가 확진검사로 사용되고 있으나 이번 호에서는 에이즈의 전반적인 검사를 모두 실어 이해를 돕고자 한다.

The Ship Safety Act prescribes matters necessary for the maintenance of seaworthiness and safe navigation of ships. In this regard, Article 10 of this Act requires shipowner to undergo occasional survey if he/she wants to temporarily change intends to modify the details entered in a ship survey certificate. Such measures are in accordance with the maintenance of the state of the ship after the ship inspection under Article 15 of this Act, and this Act includes "harbor construction work ship" under Article 39 Paragraph (1) of the Harbor Act. However, although the harbor construction work ship originally showed the same operating system as the barge, it was not applied to the Ship Safety Act and was registered and surveyed under the Construction Machinery Management Act. Then "Seokjeong No. 36" sinking accident in Ulsan on December 14, 2012, led to the amendment of the Harbor Act in 2016, and considering the fact that it was added to the Ship Safety Act and applied, there is a realistic limit to applying all the regulations stipulated in the Ship Safety Act to the harbor construction work ship. Accordingly, this study discusses the work characteristics through concept, registration, work area, survey regulations, application case of temporary alteration etc. of harbor construction work ships and controversial issues related to the scope of application of the Ship Safety Act of actual harbor construction work ships, and also the appropriate scope of "temporary alteration" among temporary inspections prescribed in Article 10 of the Ship Safety Act in consideration of the legislative purpose of incorporating harbor construction work ships into the survey subject to the Ship Safety Act in accordance with the revision of the Harbor Act.

Purpose: Several studies report that detection of thyroglobulin (Tg) in fine-needle aspiration (FNA) biopsy washout fluid from lymph nodes identifies recurrences or metastases of differentiated papillary thyroid cancer (DPTC) in the neck with higher sensitivity and specificity than fine-needle aspiration cytology (FNAC). We evaluate the diagnostic efficacy and usefulness of Tg measurement in FNA washout fluid (FNA-Tg) and compare with FNAC. Materials and Methods: Forty-eight FNA samples of 37 patients who undergone ultrasonography to detect cervical lymph node metastasis of DPTC, were included for this study. Lymph node metastasis was confirmed by histopathologic examination or long-term imaging follow-up. Sensitivity, specificity and accuracy of FNA-Tg and FNAC were calculated. In 34 patients, we evaluated diagnostic accuracy of FNA-Tg according to the presence or absence of Tg antibody. Results: Sensitivity, specificity and accuracy of FNAC were 75.0%, 97.2% and 91.7%, respectively, and those of FNA-Tg were 100%, 88.9% and 91.7%, respectively. The presence of Tg antibody was not relevant to the diagnostic accuracy of FNA-Tg. Conclusion: FNA-Tg is a as accurate as FNAC with higher sensitivity. FNA-Tg and FNAC are complement techniques for diagnosing lymph node metastasis of DTPC.

Purpose: This study compared the quantity of phoria for distance by new method with that by existing methods. Methods: For this study, it was selected to two existing phoria measurements, von Graefe and Maddox rod. And new method named "3D polarizing phoria measurement" was designed to measure the quantity of phoria using polarizing glasses and 3D display. Unlike existing measurement using polarized lens, newly considered method measured the quantity of phoria in condition removed perfect binocular fusion using field stop on apparatus and polarized lens. For using new method for distance, it was developed a phoria test chart. It supports three kinds of phoria measurements. Subjects were 12 (male 6, female 6). They had three phoria tests (1 sets) including new method. It was considered the effect of experimental order, so we tested all cases about experimental order. The number of cases was 6 sets, and the sample size in this experiment was 72 sets. For removing binocular fusion, lighting of the laboratory that was below 10 lx and the background color of phoria test chart was dark, RGB=(20, 20, 20). Results: Subjects were sorted into three groups. Samples with exophoria and orthophoria were 30 sets each, and those with esophoria were 12 sets. The quantity of phoria measured three tests differ from each other like "newmethod < von Graefe < Maddox rod", and there were statistically significant difference each other. Conclusions: This study has great significance in the sense that new method was the measurement with naturally removing binocular fusion without dizziness during the tests.

개의 전립선에서 경직장 초음파상에 나타나는 미만성 저에코영역의 성상과 경직장 초음파 검사법의 유용성을 알아보기 위해 히스토그람 분석방법과 color doppler 초음파를 이용하여 전립선 맛사지에 따른 전립선 실질의 에코변화를 비교하였다. 전립선 맛사지 후 히스토그람상의 휘도치는 전립선 요도부 기준 상부측 실질내에서 유의성(p<0.01) 있게 고에코로 변화되어 나타났으며, 전립선내에 분포하는 혈관은 저에코영역에서 보다 고에코영역에서 발견되었다. 이상의 결과로 보아 경직장 초음파 검사법은 전립선의 미세한 변화에 대해 보다 상세한 실질내의 정보를 제공할 수 있는 효과적인 검사 방법이며, 맛사지에 따른 휘도치의 변화는 전립선의 물리적 자극에 대한 전립선액의 분비에 따른 결과로 사료되고, 저에코영역은 혈관보다는 전립선액이 점유하고 있는 것으로 생각된다.

적청 색필터와 새로운 시표를 이용한 교대가림법(Twinkle R/B법)이 임상적으로 새로운 사위검사법으로 사용될 수 있는지 그 가능성을 평가하였다. 대학생 109명(남 73명, 여 36명)을 대상으로 Twinkle R/B법, Modified Thorington법, Howell법, 그리고 Von Graefe법으로 40cm 거리에서 사위검사를 실시하였다. 사위검사는 검사자별로 반복 측정을 실시하여 검사방법에 따른 신뢰도를 평가하였다. 실험 결과, 검사자의 반복측정에 따른 신뢰도는 Twinkle R/B법이 가장 높았다. 결과적으로 Twinkle R/B법은 신뢰도가 높은 사위검사법으로서 임상에서 충분히 사용 가능한 것으로 나타났다.
