2017년 10월 31일, 미국 맨해튼에서 ISIS를 추종하는 사이포브가 트럭으로 강변 자전거 도로에 난입하여 8명이 사망하고 20여명이 부상하는 테러 발생, 2017년 6월 5일, 이슬람 극단주의자 야쿱 카이리는 호주 멜버른 교회지역에서 여성을 납치하여 인질극을 벌이다 경찰에 사살되는 등 영국, 프랑스, 독일 등 세계 각 지역에서 테러와의 전쟁이 벌어지고 있다. 수법은 정부 요인 등 주요 하드타겟(Hard target)에서 불특정다수의 소프트타겟(Soft target)으로 바뀌면서 국민들의 공포감을 키웠고, 국가나 조직이 주도를 하던 방식에서 ISIS 등 추종세력이 독단으로 테러를 시도하는 자생테러로 바뀌었다. 또한, 일상생활에서 쉽게 구할 수 있는 차량, 압력 밥솥 등을 테러에 이용하면서 이에 대한 경찰의 대비도 어렵게 되었다. 한편, 일부 테러관련 학자들은 2001년 9월 11일 미국 세계무역센터 테러나 2016년 7월 14일 프랑스 니스 트럭 테러 같이 경찰에게 시간적 여유를 주지 않고 테러를 저지르는 사례들을 예로 들면서 이제는 경찰의 대화기법(협상)이 무용지물이며 전술적인 진압방법을 발전 시켜야 한다는 주장을 펼치기도 한다. 이와 관련, 본 연구에서는 경찰의 협상기법이 테러뿐만 아니라 지구대 파출소에서 만날 수 있는 주취자 등 경찰의 업무 전반에 필요한 부분임을 강조하면서 경찰기관의 대화법의 활성화 방향에 대한 대책을 제시하고자 한다.

Purpose: This study compared the diagnostic accuracy of cone-beam computed tomography (CBCT) scans obtained with 2 CBCT systems with high- and low-resolution modes for the detection of root perforations in endodontically treated mandibular molars. Materials and Methods: The root canals of 72 mandibular molars were cleaned and shaped. Perforations measuring 0.2, 0.3, and 0.4 mm in diameter were created at the furcation area of 48 roots, simulating strip perforations, or on the external surfaces of 48 roots, simulating root perforations. Forty-eight roots remained intact(control group). The roots were filled using gutta-percha (Gapadent, Tianjin, China) and AH26 sealer (Dentsply Maillefer, Ballaigues, Switzerland). The CBCT scans were obtained using the NewTom 3G (QR srl, Verona, Italy) and Cranex 3D (Soredex, Helsinki, Finland) CBCT systems in high- and low-resolution modes, and were evaluated by 2 observers. The chi-square test was used to assess the nominal variables. Results: In strip perforations, the accuracies of low- and high-resolution modes were 75% and 83% for NewTom 3G and 67% and 69% for Cranex 3D. In root perforations, the accuracies of low- and high-resolution modes were 79% and 83% for NewTom 3G and was 56% and 73% for Cranex 3D. Conclusion: The accuracy of the 2 CBCT systems was different for the detection of strip and root perforations. The Cranex 3D had non-significantly higher accuracy than the NewTom 3G. In both scanners, the high-resolution mode yielded significantly higher accuracy than the low-resolution mode. The diagnostic accuracy of CBCT scans was not affected by the perforation diameter.

Background: The aim of this work was the comparison between the carcass and the meat ewes of the regional Traditional market and the Islamic religious (Halal) market. Methods: Thirty and 20 at the end of career traditional market and Halal market ewes were slaughtered following the EC (European Council, 2009) animal welfare guidelines. Live weight of ewes was taken and dressing percentage of carcasses was calculated. On every carcass zoometric measurement and the evaluation trough the EU grid rules were performed. On the Musculus longissimus thoracis of 12 Traditional market carcasses and 11 Halal market carcasses the physical-chemical and nutritional analysis were performed. Consumer tests for liking meat ewe were performed in order to find consumer's preference level for Traditional and Halal markets ewe meat. Considering as fixed factor the ewe meat market (Traditional and Halal), results were submitted to oneway Analysis of Variance (ANOVA) and to Principal Component Analysis (PCA). Results: The Halal market ewes have shown lower dressing percentages ($42.91{\pm}0.82$ vs $46.42{\pm}0.69$) and lower conformation score ($4.5{\pm}0.5$ vs $7.8{\pm}0.4$). The Halal market meat showed higher cooking loss in oven ($37.83{\pm}1.20$ vs $32.03{\pm}1.15%$), lesser Chroma value ($18.63{\pm}0.70$ vs $21.84{\pm}0.67$), and lesser Hue angle value ($0.26{\pm}0.02$ vs $0.34{\pm}0.02$). This product had also lower fat percentage ($4.2{\pm}0.4$ vs $7.09{\pm}0.4$). The traditional market meat had higher percentage in monounsatured fatty acids (MUFA) ($43.84{\pm}1.05$ vs $38.22{\pm}1.10$), while the Halal market meat had higher percentage in ${\omega}3$ poliunsatured fatty acids (PUFA) ($5.04{\pm}0.42$ vs $3.60{\pm}0.40$). The consumer test showed as the ewe meat was appreciate by the consumers. Conclusions: Both meat typologies have shown good nutritional characteristics. The traditional market meat had higher MUFA composition, and a better MUFA/satured fatty acids (SFA) ratio, while the Halal market meat had higher PUFA composition. These results were also supported by the PCA. The consumers preferred the traditional market meat.

Inelastic static pushover analysis has been used in the academic-research widely for seismic analysis of structures. Nowadays, the variety pushover analysis methods have been developed, including Modal pushover, Adaptive pushover, and Cyclic pushover, in which some weaknesses of the conventional pushover method have been rectified. In the conventional pushover analysis method, the effects of cumulative growth of cracks are not considered on the reduction of strength and stiffness of RC members that occur during earthquake or cyclic loading. Therefore, the Cyclic Pushover Analysis Method (CPA) has been proposed. This method is a powerful technique for seismic evaluation of regular reinforced concrete buildings in which the first mode of them is dominant. Since the bridges have different structures than buildings, their results cannot necessarily be attributed to bridges, and more research is needed. In this study, a cyclic pushover analysis with four loading protocols (suggested by valid references) by the Opensees software was conducted for seismic evaluation of two regular reinforce concrete bridges. The modeling method was validated with the comparison of the analytical and experimental results under both cyclic and dynamic loading. The failure mode of the piers was considered in two-mode of flexural failure and also a flexural-shear failure. Along with the cyclic analysis, conventional analysis has been studied. Also, the nonlinear incremental dynamic analysis (IDA) method has been used to examine and compare the results of pushover analyses. The time history of 20 far-field earthquake records was used to conduct IDA. After analysis, the base shear vs. displacement in the middle of the deck was drawn. The obtained results show that the cyclic pushover analysis method is able to evaluate an accurate seismic behavior of the reinforced concrete piers of the bridges. Based on the results, the cyclic pushover has proper convergence with IDA. Its accuracy was much higher than the conventional pushover, in which the bridge piers failed in flexural-shear mode. But, in the flexural failure mode, the results of each two pushover methods were close approximately. Besides, the cyclic pushover method with ACI loading protocol, and ATC-24 loading protocol, can provided more accurate results for evaluating the seismic investigation of the bridges, specially if the bridge piers are failed in flexural-shear failure mode.

본 연구는 고대 근동 및 그리스·로마의 기록관과 연계한 도서관 명칭의 기원과 변용을 추적하였다. 첫째, 도서관이란 말의 기원은 두 갈래다. 하나는 고대 그리스어 βιβλιοθήκη에서 라틴어 bibliothēkē가 파생되었고 최초 흔적은 2세기 후반 폴룩스의 「Onomasticon」이고, 문헌 텍스트 집합으로 간주하면 1602년 립시우스의 「De Bibliothecis Syntagma」다. 다른 하나는 라틴어 libraria가 고대 프랑스어 librairie로 변용된 후 14세기 초 library로 정착되었다. 영어 library는 1374년 초서가 조어하였다. 둘째, 고대 근동의 점토판 보존소는 기록관에 가깝지만 공식 명칭은 알 수 없다. 그러나 아슈르바니팔 점토판 보존소는 기록학계의 원질서 존중 및 출처주의 원칙과 거리가 멀기 때문에 왕실기록관이 아닌 왕립도서관의 원형이다. 알렉산드리아도서관의 공식 명칭은 'Βιβλιοθήκη της Αλεξάνδρειας'이었고 'ALEXANDRINA BYBLIOTHECE'로 변용되었다. 셋째, 고대 그리스·로마에서는 기록관과 도서관이 분리되었다. 그리스 도서관은 체육관 부설 도서실 수준이었고, 독립된 명칭은 거의 없었다. 목욕탕에 많이 부설된 로마 도서관의 명칭은 βιβλιοθήκη과 Bibliotheca이 혼용되었다. 마지막으로 고대 도서관은 중세 수도원 도서관으로 계승되었고, 이슬람제국에서는 '바이트 알-히크마'로 변용되었다. 한중일에서는 19세기말 화제한어 도서관이 수용되었으나 쟁점이 많아 후속연구가 필요하다.

Objective: The objective was to evaluate the influence of different dietary crude protein (CP) levels during the growth phase on reproductive characteristics and reproductive efficiency as well as the body development of adult male Japanese quail. Methods: Three hundred one-day-old male quails were distributed into five treatments with diets containing different CP levels (18%, 20%, 22%, 24%, and 26%) in a completely randomized design, with six replicates of ten birds each. The CP diets were applied only during the growth phase (1 to 35 days). At 36 days of age, the birds were transferred to 30 laying cages with three males and nine females each, and all birds received the same diet formulated to meet production-phase requirements until 96 days of age. Results: The growth rate of the birds increased linearly (p<0.01) with increasing dietary CP, but the age of maximum growth decreased (p<0.05). At growth maturity, all birds had the same body weight (p>0.05). At 35 days of age, higher weight gain was obtained (p<0.05) with diets containing 22% CP or higher. No effects on feed conversion were observed in this phase. The increase in dietary CP enhanced (p<0.01) nitrogen intake and nitrogen excretion but did not affect (p>0.05) nitrogen retention. Testis size, seminiferous tubular area, number of spermatogonia, and germinal epithelial height at 35 days of age increased linearly (p<0.05) with dietary CP, while the number of Leydig cells decreased (p<0.01). The Sertoli cell number at 60 days of age increased linearly (p<0.01) with dietary CP. Dietary CP levels did not affect cloacal gland size, foam weight, foam protein concentration, semen volume, or flock fertility at 90 days of age. Conclusion: Dietary CP concentration affected body and testicular development in male Japanese quails but did not affect reproductive efficiency.

Objectives: Asthma is a chronic disease, and the demand for herbal medicines in this field has increased in recent years. The new findings highlight the role of the gut-lung axis in the pathophysiology of asthma. Hence, this study will evaluate the safety and efficacy of Glasthma syrup, an herbal formula based on Persian medicine, in improving asthma and regulating intestinal permeability. The formula consists of five herbal ingredients that have anti-inflammatory effects on the respiratory tract, also known as gut tonics. Methods: The study will be conducted as a placebo-controlled, triple-blind, randomized trial. It will consist of a 4-week intervention followed by a 4-week follow-up period. The target sample size is 20 patients with moderate asthma aged 18 to 60 years. Eligible participants will be randomly assigned to either the experimental group or the control group in equal numbers. Patients in the experimental group will take Glasthma syrup (7.5 mL, twice a day), while patients in the control group will take a matching placebo. Both groups will receive a 4-week combination of a long-acting beta2 agonist and a leukotriene modulator as standard of care. Inhaled corticosteroids can be used as rescue medication as needed. Results: The primary outcomes are asthma symptom scale, lung function, and intestinal permeability. Secondary outcomes include quality of life, symptom recurrence rates, and blood tests. A safety assessment will also be conducted during the trial. Conclusion: In this trial, the effects of Glasthma syrup in patients with moderate asthma will be examined. The study will also assess the effects of the formulation on the gut-lung axis by simultaneously monitoring the gut permeability index, asthma symptoms, and lung function.

Background and Objectives: Autosomal recessive non-syndromic hearing loss (ARNSHL) with genetic origin is common (1/2000 births). ARNSHL can be associated with mutations in gap junction protein beta 2 (GJB2). To this end, this cohort investigation aimed to find the contribution of GJB2 gene mutations with the genotype-phenotype correlations in 45 ARNSHL cases in the Kurdish population. Subjects and Methods: Genomic DNA was extracted from a total of 45 ARNSHL families. The linkage analysis with 3 short tandem repeat markers linked to GJB2 was performed on 45 ARNSHL families. Only 9 of these families were linked to the DFNB1 locus. All the 45 families who took part were sequenced for confirmation linkage analysis (to perform a large project). Results: A total of three different mutations were determined. Two of which [c.35delG and c.-23+1G>A (IVS1+1G>A)] were previously reported but (c.299-300delAT) mutation was novel in the Kurdish population. The homozygous pathogenic mutations of GJB2 gene was observed in nine out of the 45 families (20%), also heterozygous genotype (c.35delG/N)+(c.-23+1G>A/c.-23+1G>A) were observed in 4/45 families (8.8%). The degree of hearing loss (HL) in patients with other mutations was less severe than patients with c.35delG homozygous mutation (p<0.001). Conclusions: Our data suggest that GJB2 mutations constitute 20% of the etiology of ARNSHL in Iran; moreover, the c.35delG mutation is the most common HL cause in the Kurdish population. Therefore, these mutations should be included in the molecular testing of HL in this population.

키르기스스탄은 다자간 안보시스템에 의존한 군사안보 확보와 등거리 외교를 통한 국가안보를 국가정책의 주요 목표로 두고 추진하고 있다. 부연하자면, 중앙아시아의 소국으로서 자주권의 확립과 국가발전이라는 과제를 추진하기 위하여 나름의 군사안보정책을 통하여 해결점을 찾으려 한다는 것이다. 그러나 한 국가가 단순히 외교와 외부의 안보시스템에 의존하여 국가의 자주성과 발전을 담보할 수는 없을 것이다. 이 논문에서는 키르기스스탄의 국방력과 군사력을 해부해 봄으로써 키르기스스탄이 최소한의 자위적 차원의 국방력을 가지고 있는가를 살펴보는 것과 국방력 증강에 대한 가능성을 살펴보는 것이 중요하다고 본다. 해양세력과 대륙세력, 그 양대 세력의 신-그레이트 게임속에서 등거리외교와 다자간 안보협력기구를 통하여 국가자주성을 확보해 나가는 균형 외교전략의 한계와 미래를 살펴봄으로서 앞으로의 키르기스스탄 독립과 자주 문제를 파악, 예측 해 보는 것이 본 논문의 목적이다.
