In this study, the variation of indoor and soil radon concentrations were measured at a test bed (detached house), and correlation analysis was performed using linear regression. The results showed that the average concentration of indoor radon was increased by about 20% when the heater was operated in the house, but it was decreased by 15% when the ventilation system was on. In the changes of seasonal radon concentrations, soil and indoor radon concentrations in winter were higher than in summer. Statistical analysis showed a weak correlation between the soil radon and indoor radon, but the correlation (R=0.852, $R^2=0.726$) was relatively high at exhaust condition in the winter. It is difficult to extrapolate the results of the study to the general cases because radon distribution is highly site-specific, but the result of this study could be used as a reference for radon management and reduction of detached house in the future investigations.

This paper reports the fabrication and characterization of $5\;\times\;5$ thermal cantilever array for nano-scaled memory device application. The $5\;\times\;5$ thermal cantilever array with integrated tip heater has been fabricated with MEMS technology on SOI wafer using 7 photo masking steps. All single-level cantilevers have a diode in order to eliminate any electrical cross-talk between adjacent tips. Electrical measurements of fabricated thermal cantilever away show its own thermal heating mechanism. Thermal heating is demonstrated by the reflow of coated photoresist on the cantilever array surface.

Zn wires have been electrically exploded in methanol or distilled water using the pulsed power technologies. The nanopowders produced by the explosions have been observed by using SEM and TEM, and analyzed its phase by using EDS and XRD. The nanopowders produced in distilled water showed ZnO phase only. On the other hands, the nanopowder produced in methanol showed mixed phases with Zn and ZnO. The HR-TEM images of the nanopowders produced in methanol showed that the some particles have been coated with carbon like materials. It is considered that the carbon coatings could be depended on the positions of the particles during the plasma state formed by explosion.

Purpose: Thyroglossal duct cyst (TGDC) is known to be the most common midline neck mass in children, but the adult population still has this abnormality. The most common symptom of TGDC is a simple neck mass, and differential diagnosis among other abnormalities is important. The aim of this study is to perform a retrospective view of TGDC in order to describe any differences in clinical features, diagnostic tools, treatment, and outcomes in children and adults who underwent surgery in a single institution, and to determine its clinical implications. Methods: We performed a retrospective chart review on 75 pathologically diagnosed TGDC patients from 1995 to 2013 who were divided into two groups: children (≤18 years) and adults. Comparison analysis was performed for age, sex, site and location of cyst, size, diagnostic tool, surgical method, and postoperative outcome. Results: Our study showed frequent occurrence of TGDC in adults. There was no significant sex, site, or location difference in the occurrence of TGDC in children and adults, however, the size of cyst in adults was larger than that in children (mean, 2.80 cm vs 2.15 cm) (P< 0.001). Four patients (5.3%) had postoperative recurrence of TGDC, and Sistrunk operation showed lower recurrence rate than excision (3.1% vs 18.2%) (P<0.040). Two malignancy cases were identified postoperatively in adults. Conclusion: Particularly in adults, the possibility of carcinoma would make it important to perform fine-needle aspiration for differential diagnosis. Sistrunk procedure will remain the treatment of choice for most TGDC patients considering recurrence risk.

Nickel wires of 0.8 mm in diameter and 80 mm in length were electrically exploded in liquid media such as water, ethyl alcohol. The distribution of particle sizes was broad from a few micrometers to tens of nanometer. It was identified that the particles could be classified according to its sizes by using centrifugal separator. The powder prepared in distilled water showed mainly pure metallic Ni phase although a little oxide phase was observed. The powders prepared in ethyl alcohol showed complicated unknown phases, which is attributed to the compound of carbon in the organic liquid. This unknown phase was turned to pure metallic Ni phase after heat treatment.

특집 논문 : 시민사회와 공공성 ; 지구화, 텅 빈 생명, 페미니즘: 공공성의 변화와 여성운동의 대응

조주현 ( Joo Hyun Cho ) 한양대학교 제3섹터연구소 2007 시민사회와 NGO Vol.5 No.1

이 글은 공공성의 변화를 페미니스트 관점에서 다음 두 측면을 중심으로 논의한다. 첫째, 지구화의 영향으로 국민국가 단위의 근대적 공사 구분이 무의미해지게 되고 국가, 인종, 계급, 성별이 상호교차하는 상황에서 계급정체성을 형성하기는 더욱 어려워진 반면, 여성 비정규직화와 노동 유연화의 결과로 여성경제활동은 증가하고 남성 중산층은 몰락함에 따라 결혼, 가족, 성별 관계에 있어 전지구적 변화가 예상되며 이에 따라 여성운동은 새로운 틀을 모색할 것과 시민 운동에서 주도적인 역할을 할 것을 기대 받는다. 둘째, 정치적으로 국가권력은 국가의 통치권이 적용되지 않는 배제의 공간을 확장시킴으로써 배제의 공간을 지배하는 생명정치를 확산시킨다. 공공성이 작동하는 공적 영역 너머의 배제의 공간에 존재하는 개인은 시민권이 박탈된 ``텅 빈 생명``으로 환원되어 국가폭력의 대상으로 부상한다. 여성운동은 여성들의 삶의 방식을 반영하는 공공성의 새로운 기준을 주장하는 동시에, 공공성의 영역을 잠식하는 배제의 공간이 확장되는 것을 막을 수 있는 새로운 패러다임을 구성하기 위해 문화번역자로서의 위치에 대한 성찰이 필요함을 주장한다. In this work, the transformation of publicness that has been going on recently is discussed from the feminist standpoint, focusing on the following two aspects. First, while the globalization rendered the modern public/private distinction at the level of nation-state meaningless and forming the class identity in the context of intersecting nation, race, and gender became a more difficult task, increasing women`s economic activity and dwindling male middle class due to the transformation of women workers into non-regular workers and accompanying increase of labor flexibility are expected to cause global restructuring of marriage, family, gender relations, forcing women`s movement to search for a new framework and to take over a leading role in civil movements. Second, politically the state power expands the space of exclusion where the sovereign power of state cannot be exercised, thereby proliferating the bio-power that dominates this space of exclusion. The individual that resides in the space of exclusion existing beyond the horizon of public space where publicness operates is reduced to homo sacer deprived of citizenship, hence emerges as an object subjected to violence of nation-state. Women`s movement should subject itself under careful scrutinization of its role as an cultural translator/interpreter that should not only propose a new criterion of publicness that properly reflects women`s way of life, but develop a new paradigm that could spoil the expansion of space of exclusion that is encroaching the space of publicness.

A uniform systematic and administrative support is needed for these facilities to function properly. Therefore, the purpose of this study was to review the current situations of the daycare facilities for infants and preschoolers with disabilities and to propose the possible measures for their improvements to be vitalized. The followings are the improvement measures proposed on the basis of the results of this study. Firstly, infants and preschoolers with disabilities should have the priority when admitted newly for the daycare centers and the concrete admission requirements should be specified based on the types and the severities of their disabilities. Also, national, public or corporate daycare facilities should be obligated to share 10% of their total admissions to infants and preschoolers with disabilities. Secondly, the daycare for infants and preschoolers should be the top priority for the daycare policies. The daycare facilities for infants and preschoolers with disabilities should be provide specialized education and various medical treatment services and integrated daycare facilities to provide part-time care services. Also, various early intervention service model should be developed and applied. However, infants and preschoolers for the after-school cares should be transferred to children"s welfare institutes in the future. Thirdly, the special provisions for the daycare of infants and preschoolers should be established in Mothers" and Children"s Health Act, Handicapped Persons" Welfare Act, Specialized Education Promotion Act and Infants" and Kids" Daycare Act, for the establishment of early diagnosis system for disabilities. The special rules of the daycare for infants and preschoolers with disabilities should include the following provisions for them; assessment and identification, placement and treatment, individualized education, educational support, and integrated facilities in national and public organizations. Also, infants and preschoolers should be provided with prioritized assessments, special admission requirements in accordance with the types and the severities of their disabilities, and part-time cares. The central administrative organizations should be interconnected for cooperation in order to provide inclusive welfare services for infants and preschoolers with disabilities.
