근대 이후 국민국가의 출현으로 국가 시민성이 강조되어 온 것이 사실이다. 그러나 최근 세계화의 물결 속에서 경계화된 영역을 통해 담보되고 공고히 되는 국가 시민성의 영향력은 갈수록 줄어들고 있다. 세계화는 한 국가의 시민들로 하여금 밖으로는 지구촌 사회에 걸맞는 글로벌 시민성을, 안으로는 다문화 사회에 적합한 문화적 시민성을 요구하고 있다. 이러한 경향은 시민성에 대한 지리적 초점이 정치적 영역에서 점차 사회적 문화적 영역으로 이동 확장하고 있음을 보여주는 것이다. 뿐만 아니라 개인의 일상적인 측면 역시 강조되면서, 시민성은 서구적 관점에서 표준화된 개인에서 젠더, 연령, 계층, 민족 등의 사회적 차이에 근거한 비서구적 관점, 즉 미시적인 일상적 공간에서의 포섭과 배제로 확장되고 있다. 이처럼 개인의 충성과 의무를 강조하는 국가 시민성 일변도에서 벗어나 개인의 권리와 차이를 강조하는 문화적 시민성과 일상적 시민성이라는 새로운 시민성의 공간이 도래하고 있는 것이다. 이는 한 국가가 공통적인 국가 시민성을 구축해야 하는 과제와 함께, 개인 또는 시민의 다양성 역시 인정해야 하는 도전에 직면하고 있음을 말해 준다.

Background: Primary hepatic neuroendocrine carcinoma (PHNEC) is rarer than extrahepatic gastrointestinal neuroendocrine carcinoma (NEC). It is difficult to make a correct diagnosis and poses a challenge for management. Materials and Methods: Ten PHNEC patients were admitted to our hospital from June 2006 to June 2011. Laboratory tests and imaging scans were performed for diagnosis and exclusion of extrahepatic NEC. All patients were AFP - and CA199-. Seven patients had solid tumors with cystic changes on ultrasonography, CT and/or MRI. For the initial treatment, four patients received combined-therapy and six monotherapy. Considering overall treatment, six patients received combined-therapy and four patients monotherapy. Staging criteria of primary hepatocellular carcinoma (PHC, AJCC 7th edition) were used to differentiate the stage of all patients: 3 patients were stage I, 2 stageII, 4 patients stageIII and 1 stageIV. All patients were followed up and clinical data were gathered. Results: The median follow-up duration was 38.5 months. The 1-year, 2-year, 3-year and 6-year disease-free survival was 80.0%, 46.2% and 46.2% and 0% respectively. The overall survival rates were 100%, 67.1%, 67.1% and 33.6% respectively. Patients in early-stages (I/II) had similar disease-free and overall survival as those in advanced-stages (III/IV). Patients with monotherapy had significant shorter disease-free and overall survival than the patients with combination-therapy. Conclusions: PHNEC has a unique specificity during its occurrence and development. The staging criteria of PHC might not be suitable for the PHENT. More convenient and effective features need to be found in imaging and laboratory detection. Surgical resection, TACE, chemotherapy and radiofrequency ablation should be performed in combination and actively for patients with PHNEC or recurrence to get the best effectiveness; they might extend the disease-free and overall survival.

Objective : Craniovertebral junctional anomalies constitute a technical challenge. Surgical opening of atlantoaxial joint region is a complex procedure especially in patients with nuchal deformity like basilar invagination. This region has actually very complicated anatomical and functional characteristics, including multiple joints providing extension, flexion, and wide rotation. In fact, it is also a bottleneck region where bones, neural structures, and blood vessels are located. Stabilization surgery regarding this region should consider the fact that the area exposes excessive and life-long stress due to complex movements and human posture. Therefore, all options should be considered for surgical stabilization, and they could be interchanged during the surgery, if required. Methods : A 53-year-old male patient applied to outpatients' clinic with complaints of head and neck pain persisting for a long time. Physical examination was normal except increased deep tendon reflexes. The patient was on long-term corticosteroid due to an allergic disease. Magnetic resonance imaging and computed tomography findings indicated basilar invagination and atlantoaxial dislocation.The patient underwent C0-C3-C4 (lateral mass) and additional C0-C2 (translaminar) stabilization surgery. Results : In routine practice, the sites where rods are bound to occipital plates were placed as paramedian. Instead, we inserted lateral mass screw to the sites where occipital screws were inserted on the occipital plate, thereby creating a site where extra rod could be bound.When C2 translaminar screw is inserted, screw caps remain on the median plane, which makes them difficult to bind to contralateral system. These bind directly to occipital plate without any connection from this region to the contralateral system.Advantages of this technique include easy insertion of C2 translaminar screws, presence of increased screw sizes, and exclusion of pullout forces onto the screw from neck movements. Another advantage of the technique is the median placement of the rod; i.e., thick part of the occipital bone is in alignment with axial loading. Conclusion : We believe that this technique, which could be easily performed as adjuvant to classical stabilization surgery with no need for special screw and rod, may improve distraction force in patients with low bone density.

In an effort to expand working opportunities for women and encourage childbirth, the government of Korea introduced the free infant care policy in 2013. This policy, however, was controversial with regard to issues, such as budget shortages and dissatisfaction based on socioeconomic status. In addition, the lack of evidence-based data regarding adequate age criteria for the entry of children into childcare facilities was noted as a challenge. As child development professionals who are concerned with mental health issues, we investigated the influence and challenges of the free infant care policy with regard to infant mental health. In this review, we examined the policies enacted by developed countries, such as the United Kingdom (UK), and compared them with those in Korea. The childcare systems in Korea and the UK differ historically and socially, but show some similarities, such as maternal responsibility for parenting and household issues. Like Korea, the need for UK childcare facilities increased in the 1990's in response to market recovery and associated increase in female employment. Among the new policies in the UK, the Sure Start program has begun to provide integrated services for infants, particularly to those 0-4 years of age, who are vulnerable to social exclusion. Similar to the Dream Start program in Korea, it has been successful in providing family-related services, resulting in improvements in problematic behaviors of children, enhanced parenting skills, and decreased rates of severely injured children.

휘발성 유기 화합물 기반의 접착제를 대체하고자 천연 재료에 대한 수요가 늘고 있지만, 제조 및 생산의 전 과정에서 휘발성 유기화합물 사용을 일절 배제할 경우, 제조의 곤란, 생산성 및 보존성의 저하 등의 단점이 나타났다. 본 연구에서는 해조류의 카라기난 성분을 이용해 천연바이오 접착제를 제조하고 종이 접착제로서의 가능성을 확인해보고자 하였다. 카라기난을 이용한 액상형 바이오 종이 접착제의 제조에서 carrageenan의 겔화는 접착제의 제조과정, 발림성, 균일성, 접착 강도의 문제를 나타내게 된다. 이를 위하여 추출된 전체 carrageenan 중에서 λ-carrageenan만을 분리하여 사용하였으며 이로 인하여 매우 안정된 종이 접착제의 제조가 가능하였다. 최종 조성은 λ-carrageenan 52.0 ± 1.0%, polyvinylpyrrolidone 30.5 ± 0.5%, ethylhexylglycerin 1.0 ± 0.05%, glycerin 1.5 ± 0.05%, dextrine 13.5 ± 0.5%, 식품용 소포제 FD330A 0.6 ± 0.05%의 조성이었다. 이들이 나타내는 점도는 1.13 ± 0.07 × 10⁵ cPs (25℃), pH 6.22, 건조속도 15 min, △b^* -10.79, △E^*ab 8.18의 자외선 열화 결과를 나타내고 있었으며 44.63 kgf/cm²의 매우 우수한 접착 강도를 나타내고 있었다. 이 접착제는 TVOC, HCHO 및 중금속 모두에서 불검출 결과를 나타내었으며 총호기성생균수 측정과 ASTM G 21-15 시험법에 의하여 곰팡이 challenge test에서도 곰팡이에 대한 우수한 저항성 결과를 나타내고 있어서 접착제의 항속성에서도 우수한 결과를 나타내고 있는 것으로 보인다.
