정찬권 국가안보전략연구원 2014 신안보연구 Vol.- No.182

The purpose of this study is to improve the current National crisis Management System. We have been threaten the national security and people's safety life caused by The North Korea's an armed advocation, disaster, climate crisis, and critical infrastructure crisis etc. So we need to establish the integrated and unified response organization. but There are some difficulty and other obstacles for the successful National Crisis Management System ; ambiguity of Control tower role, weakness of law's hierarchy, lack of speciality of man power, unsustainable Political leadership, and so on. In order to improve the ability of National crisis management system, I suggest the following steps be followed. First, We must to restructure operating system of the National Crisis management Control tower. Second, we need to establish tentative name "the Ministry of National Crisis Management" as directly belonging to the President. Third, relevant laws and regulation should be revised or establish a National crisis management Act as soon as possible. Forth, the government need to establish teaching institutions by which administrators can learn the theories and real fields about the crisis management. Lastly, for more effective crisis management, we need to construct the governance system because of crisis response environment changed. Accordingly, the government should cooperate with other sectors, such NGOs, volunteers and corporations. In conclusion, the government has to redesign their weak crisis management system. Successful national crisis management system depend on governmental strong will and execution for the sake of national security and safety. 본 연구에서는 21세기 포괄적 안보위협을 효율적으로 대응하기 위해 무력도발, 정치·외교, 재난, 국가핵심기반 등 주요 국가위기 사례를 분석하여 차후 국가위기관리체계의 발전방향을 제시하였다. 주요 내용으로는 첫째, 국가차원의 위기관리 컨트롤 타워 운영체계를 보완해야 한다. 둘째, 민방위·비상대비·재난 등을 하나로 묶어 가칭 “국가위기관리부”를 신설해야 한다. 만약 제한될 경우 민방위·비상대비를 통합하여 가칭 “비상민방위처”를, 그리고 안전행정부와 소방방재청의 재난기능을 묶어 가칭 “재난관리청”을 신설해야 한다. 셋째, 지방자치단체의 위기관리체계를 전면적으로 보완·강화해야 한다. 넷째, 가칭“국가위기관리기본법”을 제정하여 국가위기관리체계구축과 운영을 뒷받침해야 한다. 다섯째, 민관협력(Governance)체제를 구축해야 한다. 마지막으로 종합상황실의 단일화 운영, 재난전문대응군 창설 그리고 지방자치경찰제 도입 등도 적극 검토하여 개선해야 한다. 실효적인 국가위기관리체계구축과 운영은 정부의 의지와 실행에 달려있다고 본다.

The cytologic diagnosis of the follicular variant of papillary thyroid carcinoma (FVPTC) has become one of the common causes of false negative diagnoses when performing fine needle aspiration cytology (FNAC) of the thyroid gland. We retrospectively reviewed all the aspirates for which a diagnosis of FVPTC had been made based on the surgically excised specimens, regardless of the cytologic diagnosis. 145 FNACs was performed in 135 patients. The cytologic diagnoses were categorized as 2 unsatisfactory specimens (1.4%), 16 benign (11.0%), 49 atypical (33.8%) and 78 malignant lesions (53.8%). The tumor cells consistently showed significant nuclear overlapping, irregular nuclei and fine chromatin in all cases; however, nuclear grooves and inclusions were scarce. Galectin-3 immunostaining was performed on the cell blocks of 65 cases and this was positive for 45 cases (69.2%). The results of our study demonstrate that the determination of minimal cytologic criteria is needed to raise the sensitivity of detecting FVPTC by FNAC, and galectin-3 immunostaining is useful to make decisions on the surgical treatment of cytologically atypical thyroid nodules.

FSCEC 광필터에 관한 연구

The capacity of telecommunication networks has been increased substantially to meet the request for tremendous rate of information traffic growth due to the demands for multimedia services. As a result, DWDM technologies are emerging to be a prevailing solution of increasing capacity and to enable optical methods of implementing network functions. With the recent movement toward 50-GHz (0.4 nm) channel spacing in DWDM systems, the need for improved components has spawned several new technologies. One such filter technology is the fiber/slab evanescent coupler. The features of the individual isolated waveguides(i.e. the fiber and the slab) play an important role in the performance of the composite structure(e.g. resonance points, FWHM, tunability). For instance, the ACP's approximately determine the resonance points fo the coupler, and the FWHM si inversely proportional to th difference in the dispersion slope of the individual isolated waveguides. For a practical design, study on the features of the DMS will be a good start, because the performance of the coupler is less sensitive to the fiber parameters than to those the external DMS.

With the recent development of the ultrahigh-speed optical time division multiplexed system, high-repetition rate optical-pulse stream generation is necessary. This is different from conventional approaches, which use fiber or integrated waveguide delay line circuits. The high-repetition-rate optical-pulse multiplication phenomenon occurs when the optical pulse's spectral width is greater than the transfer bandwidth of the coupler used. From the analysis, the output repetition rate can be controlled by using fiber couplers with different equivalent transfer bandwidths. The pulse seperation spacing is controlled by number of cascaded coupler in optical loop mirror coupler scheme.

Ultrasound-guided fine-needle aspiration (FNA) cytology is the most widely used screening and diagnostic method for thyroid nodules. Although Western guidelines for managing thyroid nodules and the Bethesda System for Reporting Thyroid Cytopathology are widely available throughout Asia, the clinical practices in Asia vary from those of Western countries. Accordingly, the Working Group of Asian Thyroid FNA Cytology encouraged group members to publish their works jointly with the same topic. The articles in this special issue focused on the history of thyroid FNA, FNA performers and interpreters, training programs of cytopathologists and cytotechnicians, staining methods, the reporting system of thyroid FNA, quality assurance programs, ancillary testing, and literature review of their own country’s products. Herein, we provide a brief overview of thyroid FNA practices in China, India, Japan, Korea, the Philippines, Taiwan, and Thailand.

Primary small cell carcinoma of the salivary gland is a rare neoplasm that accounts for approximately 1.8% of all primary major salivary gland malignancies. Because of its rarify, it is difficult to diagnose small cell carcinoma of the parotid gland by fine needle aspiration cytology(FNAC). We experienced a case of primary small cell carcinoma of the parotid gland in a 72-year-old woman who presented with two palpable masses of the left infraauricular and ocular legions of two to three month's duration, respectively. Aspirate smears from the left infraauricular area were highly cellular on necrotic and lymphocytic background and showed individually dispersed cells or three-dimensional clusters of small cells. The tumor cells were round to oval with a very high nucleocytoplasmic ratio. Nuclei were about two times the size of lymphocytes and had uniformly dispersed but hyperchromatic to pyknotic chromatin. Nucleoli were occasionally visible but were generally inconspicuous. Numerous mitotic figures were detected. The clusters of these small tumor cells exhibited angular nuclear molding, irregular nuclear outlines, and occasionally rosette like arrangement. The tumor was confirmed by histology and immunohistochemistry.

Background : Mucin phenotypic markers and CDX2 are widely expressed in gastric carcinomas, however, recent studies have produced conflicting results regarding whether the expression patterns of these markers have clinicopathologic significance. Methods : We examined samples from 217 gastric carcinoma patients immunohistochemically to determine if the expression of mucin phenotypic markers and CDX2 was correlated with postoperative survival and other clinicopathologic factors. Results : All tumors were phenotypically classified as gastric (type G, 81 cases), gastric and intestinal mixed (type GI, 55 cases), intestinal (type I, 43 cases), or unclassified (type U, 38 cases). The occurrence of type G and GI tumors was positively correlated with tumor progression whereas that of type U tumors was negatively correlated with tumor progression. CDX2 expression was correlated with type I tumors. Tumors that expressed MUC5AC or MUC6 had a better prognosis than those that did not. When the relationship between phenotype and prognosis was considered, type GI had the best prognosis, followed by type G, then type U. Conclusions : The mucin phenotypic markers may be useful for predicting tumor progression and survival in patients with gastric carcinomas. Additionally, CDX2 may play an important role in gastric carcinogenesis of type I tumors.
