        Diagnostic Benefit of Thyroglobulin Measurement in Fine-Needle Aspiration for Diagnosing Metastatic Cervical Lymph Nodes from Papillary Thyroid Cancer: Correlations with US Features

        전세,김은희,박정선,백정환,김윤숙,박도준,나동규,조보연,손규리 대한영상의학회 2009 Korean Journal of Radiology Vol.10 No.2

        Objective: Our goals were to determine the added value of fine-needle aspiration biopsy (FNAB)-thyroglobulin (Tg) measurements over FNAB-cytology alone for diagnosing metastatic nodes, and to determine whether the ultrasound features of lymph nodes can be used to identify lymph nodes that may benefit from FNAB-Tg measurement in patients with papillary thyroid cancer. Materials and Methods: We retrospectively evaluated 76 surgically proven cervical lymph nodes. Twenty-nine patients were awaiting surgery and 18 patients had undergone thyroid surgery for papillary thyroid cancer. Ultrasoundguided FNAB and Tg measurements were performed and the ultrasound features were evaluated. Results: The accuracies, sensitivities, and specificities of FNAB-cytology, FNAB-Tg, and combined FNAB-Tg/cytology were 90%, 80%, and 100%; 92%, 95%, and 90%; and 93%, 96%, and 90%, respectively. The diagnostic sensitivity of FNAB-Tg for metastatic nodes was significantly higher than that of FNAB-cytology (p = 0.011). Furthermore, combined FNAB-Tg/cytology significantly increased sensitivity (p = 0.002) and accuracy (p = 0.03) as compared with FNAB-cytology. Conclusion: Combined FNAB-Tg/cytology is significantly more sensitive and accurate at detecting metastatic nodes than FNAB-cytology alone. FNAB-Tg was better at diagnosing metastases in small lymph nodes.

        Comparative Clinical Results of Vertebroplasty Using JamshidiⓇ Needle and Bone Void Filler for Acute Vertebral Compression Fractures

        전세,최일승,권영섭,서대희,이규창,박성춘 대한척추신경외과학회 2012 Neurospine Vol.9 No.3

        Objective: Percutaneous vertebroplasty (PVP) is an effective treatment modality for management of osteoporotic compression fracture. However physicians sometimes have problems of high pressure in cement delivery and cement leakage when using JamshidiⓇ needle (JN). Bone void filler (BVF) has larger lumen which may possibly diminish these problems. This study aims to compare the radiologic and clinical outcome of JN and BVF for PVP. Methods: One hundred twenty-eight patients were treated with PVP for osteoporotic vertebral compression fracture (VCF) where 46 patients underwent PVP with JN needle and 82 patients with BVF. Radiologic outcome such as kyphotic angle and vertebral body height (VBH) and clinical outcome such as visual analog scale (VAS) scores were measured after treatment in both groups. Results: In JN PVP group, mean of 3.26 cc of polymethylmethacrylate (PMMA) were injected and 4.07 cc in BVF PVP group(p<0.001). For radiologic outcome, no significant difference in kyphotic angle reduction was observed between two groups. Cement leakage developed in 6 patients using JN PVP group and 2 patients using BVF group (p=0.025). No significant difference in improvement of VAS score was observed between JN and BVF PVP groups (p=0.43). Conclusion: For the treatment of osteoporotic VCF, usage of BVF for PVP may increase injected volume of cement, easily control the depth and direction of PMMA which may reduce cement leakage. However, improvement of VAS score did not show difference between two groups. Usage of BVF for PVP may be an alternative to JN PVP in selected cases.

        부산항 컨테이너터미널 하역시장의 안정화요인과 요율인가제의 조절효과에 관한 연구

        전세표(Seh-pyo Jun),안기명(Ki-myung Ahn),윤정희(Jung-hee Yoon) 한국항만경제학회 2016 韓國港灣經濟學會誌 Vol.32 No.4

        북항터미널과 신항터미널간의 심각한 출혈경쟁이 부산항의 경쟁력을 약화시키는 것은 부산항 컨테이너 하역시장의 중대한 문제점이다. 이러한 심각한 출혈경쟁을 방지하기 위해, 부산항만공사는 작년에 하역요율 인가제를 실시하였다. 그러나, 부산항 컨테이너 터미널 운영사들이 이를 수용하지 않으면 그 효과는 미흡할 것이다. 따라서, 본 연구의 목적은 부산항 컨테이너 하역시장에서 이러한 하역요율 인가제 실시의 효과를 검정하는 것이다. 이러한 연구목적을 달성하기 위해, 현재의 부산항 운영현황을 분석하고 선행연구를 검토하여 하역시장 안정화 요인을 추출하고 이 요인들과 인가제간의 조절효과를 검증하였다. 연구결과에 의하면, 첫째로, 세 가지 하역시장 안정화 요인(시장구조, 시장행동 그리고 부산항만공사 요인)은 안정화 효과와 매우 강한 정의 관계를 보여주고 있지만 운영사 요인은 그렇지 못한 것으로 나타나고 있다. 특히, 하역요율 덤핑규제와 같은 시장행동요인은 하역시장 안정화에 기여하는 것으로 나타나고 있다. 둘째로, 인가제 자체뿐만 아니라 하역시장 안정화 요인과 인가제간의 조절효과(상호작용효과)도 하역시장 안정화에 강한 영향을 미치는 것으로 나타나고 있다. 이러한 연구결과는 인가제 시행이 부산항 컨테이너 하역시장에 매우 중요한 정책임을 시사하는 것으로 볼 수 있다. 하역시장을 안정화하는 것이 부산항의 이미지 개선과 글로벌 선사와의 협상력을 증진시키는 데 기여할 것이다. It is a critical problem of the Busan container cargo market that serious competition between the north port terminal and the new port terminal is weakening port of Busan’s competitiveness. To avoid this serious competition, Busan Port Authority(BPA) has executed a cargo-rate approval system from last year. However if Busan’s container terminal operators do not accept this system, the execution performance will be insufficient. Therefore, the purpose of this study is to test the effect of cargo-rate approval in the Busan container cargo market. To attain this research purpose, the current situation was analyzed and the existing papers were investigated. Therefore, cargo-stabilizing factors were extracted and the moderated effect between these factors and cargo-rate approval was tested. The results are as follows. First, three cargo stabilizing factors-(market structure, market behavior, and BPA)-appear to have a strong positive impact on the stabilizing effect; however, the factors that are handled by the operators can not influence the stabilizing effect. In particular, market behavior factors, such as cargo-rate dumping restriction, contributed to stabilizing cargo market. Second, The results appear to have a strong positive impact on the moderated effect as well as the cargo-rate approval. These research results show that the execution of cargo-rate approval is important in stabilizing the cargo market. Therefore, stabilizing the cargo market will contrubute to improving the image and bargaining power of the Port of Busan.

      • 光州地域 一部 中·高等學生들의 試驗不安에 대한 硏究

        전세,정영,박상학 朝鮮大學校 附設 醫學硏究所 1997 The Medical Journal of Chosun University Vol.22 No.1

        The main purpose of this study was to investigated the relationship between test anxiety and several variables (sex, grade of school, parent's school year, academic performance, parent's occupation, religions, blood type, personality trend, etc) in middle and high school students in Kwangju City (total numbers = 1060). Test Anxiety was assessed by the TAI-K(Kim Moon Joo, 1990). The data were processed by student t-test and ANOVA . The results were as follows , 1. Female students showed significantly higher level of test anxiety scores than males (especially worry factors were more prominent than emotionality factors) 2. In the area of grade difference in test anxiety, 2nd grade students were the highest group, 3rd grade were the lowest group in high school, In middle school, 1st grade were the highest and 3rd grade were appeared the lowest score of test anxiety. 3. In the area of mothers school graduate, female student with high school graduated mother group were appeared significantly higher test anxiety scores than other groups. 4. School performance and test anxiety was correlated negatively and significantly. 5. If student dislikes Korean, Mathematics and English subjects, they experienced higher test anxiety significantly than other groups. 6. Test anxiety scores were significantly higher in groups of live with their brothers or sisters than have no brothers and sisters group. 7. In male students, one of parent was not employed group had higher test anxiety scores than employed all. 8. In female students with religion, test anxiety scores were higher than had no religion group.
