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.

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.

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.

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.

The daycare facilities for infants and Preschoolers with Disabilities can function the role of early intervention and social integration within a natural environment. 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.

난자 : 생명기술의 시선과 여성 몸 체험의 정치성

조주현(Cho Joo-hyun) 한국여성학회 2006 한국여성학 Vol.22 No.2

이 글은 황우석 교수팀의 줄기세포기술의 연결망에 “난자”가 어떻게 개입되는지, 그물적, 담론적, 사회적 요소들을 규명해보는 것을 통해, 궁극적으로 복제줄기세포기술이 여성에게 어떤 영향을 끼칠지를 논의해보려는 시도이다. 연구자는 여성이 복제줄기세포 연구에서 행위성을 확보하기 위해 모성의 책임에 기반한 여성의 인권개념이 작동할 수 있는 공간을 창출해야 함을 제안하였다. 이를 다음 세 가지 논점들을 중심으로 진행하였다. 첫째, 여성의 몸에서부터 아기, 태아, 배아, 난자의 순서로 개체화 시킨 후, 개체 간의 분리와 대립을 정당화시키는 생명기술의 시선이 난자, 배아, 태아, 아기와 유기적으로 통합된 것으로 인식하는 여성 몸의 체험과 충돌하고 있다. 둘째, 배아줄기세포 기술에서 새롭게 획득된 개체적 존재로서의 “난자”의 의미는 6,70년대 근대화 과정에서의 국가의 여성출산력 조절 정책, 80년대 국가의 출산력조절, 가부장제가족의 유지, 그리고 신출산기술의 상호규정의 결과로 나타난 성감별 후 여아낙태 현상, 90년대 시험관 아기시술을 통해 구현된 도구적 모성의 연장선상에 있다. 셋째, 여성의 재생산권을 인권의 맥락에서 공식화하고, 인권을 존중하는 국가주의의 실천이 이루어져야 한다. 이와 함께 권리 개념에 반영되지 않은 여성의 모성 경험을 사회적 현실로 언어화하고 궁극적으로 권리 개념으로 번역하는 작업의 병행이 요구된다는 점을 지적했다. This work attempts to analyse the way “egg” is inserted into the network of Professor Hwang Woo Suk's research in SCNT biotechnology by identifying its material, semiotic, and social elements and to examine the eventual implications that SCNT biotechnology has on woman. To secure woman's agency in SCNT biotechnology, the author proposes to create the space in which women's human rights based on the responsibility of motherhood can operate properly. The main part of this work can be roughly summarized by the following three arguments. First, it is emphasized that the semiotic visual biotechnology that, after individuating child, fetus, embryo, and egg in that order from woman's body, justifies separation and opposition among these objects directly runs into conflict with the women's embodied experience that recognizes child, fetus, embryo, and egg as an organically integrated whole. Second, it is argued that the concept of “egg” as an individuated being, that has been newly generated by SCNT biotechnology, is a natural offspring of those utilized by the nation-state policy to control women's fertility during 60's and 70's modernization process, the phenomenon of abortion of female fetus that occurred as a result of interaction among fertility control by the nation-state, maintenance of patriarchal family, and new reproductive technology in 80's, and the instrumental motherhood realized through IVF technology of 90's. Third, it is urged that nationalism that incorporates and reformulates woman's reproductive rights in human rights vocabulary and respects human rights thus reformulated be practised. Along with it, it is pointed out, parallel efforts to codify mothering experience, that has not been properly incorporated in the framework of human rights, into discourses as socially existing substance and, eventually, to translate into the language of human rights are needed.

철인 통치의 정당성에 관한 변론

조주현 ( Joo Hyun Cho ) 한국윤리학회 2013 倫理硏究 Vol.91 No.1

Plato has two empirical sorts of reasons for his claims about the political importance of philosophic understanding in the ‘Republic’. First, there is a motivational claim. If those who are to govern are lovers of ruling, they will not seek the good of the whole city, but will pursue political office simply for their own benefits and interests. Second, the question of who should rule notoriously creates bitter, intractable conflicts between elites and the masses. Rule by philosophers can put an end to such controversy. However, Plato`s best known justification for the rule of philosophers is epistemic. It is that philosophers alone have knowledge of what really is, e.g., just, good, and fine, and this makes them better at ruling. For Plato, what is of central importance in justifying the need for philosophers to rule is the philosophers`s knowledge of virtue. This is necessary not because such knowledge is the only way of getting right the evaluation of particular actions or laws. Rather, it is necessary because it involves a correct grasp of the central element of happiness(eudaimonia), that is, of what is the best kind of character for humans to have. That is a correct grasp of the nature and value of philosophic understanding, and such a grasp requires philosophic knowledge itself.
