A new technology of fashion show is opening the digital era and an imaginary fashion show is now arising as a new form of fashion show which allows one to enjoy a collection through the monitor without holding a real fashion show. Digital fashion show allows designer to create infinite ideas by articulating the designer's concept through not only garments but also other factors. In this research, We will analyze cases which are mixtures of digital technology and fashion show and will suggest a new paradigm of fashion show by producing an imaginary fashion show which cannot be easily articulated in an ordinary real fashion show, articulated by garments created by digital technology and graphic effects. The program used for this study is 'DC Suite 2.0' developed by Physan and Digital Clothing Center of Seoul National University, available for 2D pattern production and 3D simulation. In addition, in order to enhance representation of the visual effects, Maya's Qualoth and V-ray program which could be compatible with 'DC Suite' were used to make 3D digital fashion show.

본 논문은 마야인의 성서라고 일컬어지는 "포폴 부"를 심층생태학(Deep ecology)적 관점에서 살펴보는 작업으로 준비되었다. 기존의 "포폴 부" 연구가 신화 연구 중심으로 이루어져왔고 무엇보다 마야의 창조 신화에 대한 우화적 요소를 소개하는 형태로 전개되어온 만큼 "포폴 부"에 대한 다양한 방식의 접근이 필요하다. 따라서 본 연구는 기존 연구에서 찾기 어려운 생태학점 관점에서 마야-키체의 경전을 다시 살펴보고자 한다. 이는 신화에 가려진 포폴 부의 민낯을 찾아가는 궤적이 될 것이다. 생태학 혹은 심층 생태학적으로 작품을 고찰하고자 한 것은 무엇 보다 "포폴 부"가 다른 문화권의 창조 신화와는 층위가 다른 생태인식을 배태하고 있기 때문이다. 주지하다시피 심층생태학은 기존의 환경운동을 표층생태학이라고 비판하면서 태동한 개념으로, 자연을 대하는 인간 자신의 도덕적, 윤리적 변화를 촉구하는데, 이 때문에 필연적으로 '형이상학적' 차원의 성격을 띠게 된다. 이렇듯 심층 생태학은 무엇보다 근대 이후의 인간중심주의, 이분법적 사고, 이성중심주의를 탈피할 것을 주창한다. 마야의 "포폴 부"도 이러한 인식을 담아낸 텍스트로 심층생태학적 분석을 통해 이 작품에 내재한 유토피아적 세계관을 살펴보았다.

The purpose of this study is to analyze the relationship and effects of variables both directly and indirectly (e.g., investment (INV), government expenditure (GE), unemployment rate (UR), economic growth (EG), and income inequality). The analytical phases consist, first, to transform the data using the Log Natural (Ln) method. Second, to check normality and multicollinearity of data. Third, to test direct effects of variables (government expenditure and investment effect on the unemployment rate and economic growth; investment on government expenditure; economic growth on unemployment rate; economic growth and unemployment rate on income inequality). Fourth, to test indirect effects using Sobel test, which involves UR and EG as intervening variable. Fifth, to test hypotheses with p-value < 0.05. The results of the study reveal that, of the 12 relationships, statistics show that 11 variations of the association have significant positive and negative effects. Theoretically, the different characters and goals of GE and INV in each country will have a different impact on EG and UR goals. The study provides an input, especially for the government. To create optimal EG through GE and INV, it is necessary to allocate budgets to industrial sectors that can absorb a massive labor force and to new economic growth sectors.

Objective: To analyze the microimplant (MI) displacement pattern on treatment with a maxillary skeletal expander (MSE) using cone-beam computed tomography (CBCT). Methods: Thirty-nine participants (12 males and 27 females; mean age, 18.2 ± 4.2 years) were treated successfully with the MSE II appliance. Their pre- and post-expansion CBCT data were superimposed. The pre- and post-expansion anterior and posterior inter-MI angles, neck and apical inter-MI distance, plate angle, palatal bone thickness at the MI positions, and suture opening at the MI positions were measured and compared. Results: The jackscrew plate was slightly bent in both anterior and posterior areas. There was no significant difference in the extent of suture opening between the anterior and posterior MIs (P > 0.05). The posterior MI to hemiplate line was greater than that anteriorly (P < 0.05). The apical distance between the posterior MIs was greater than that anteriorly (P < 0.05). The palatal thickness at the anterior MIs was significantly greater than that posteriorly (P > 0.01). Conclusions: In the coronal plane, the angulation between the anterior MIs in relation to the jackscrew plate was greater than that between the posterior MIs owing to the differential palatal bone thickness.

Background: The role of the sympathetic nervous system appears to be central in causing pain in complex regional pain syndrome (CRPS). The stellate ganglion block (SGB) using additives with local anesthetics is an established treatment modality. However, literature is sparse in support of selective benefits of different additives for SGB. Hence, the authors aimed to compare the efficacy and safety of clonidine with methylprednisolone as additives to ropivacaine in the SGB for treatment of CRPS. Methods: A prospective randomized single blinded study (the investigator blinded to the study groups) was conducted among patients with CRPS-I of the upper limb, aged 18-70 years with American Society of Anaesthesiologists physical status I-III. Clonidine (15 ㎍) and methylprednisolone (40 mg) were compared as additives to 0.25% ropivacaine (5 mL) for SGB. After medical treatment for two weeks, patients in each of the two groups were given seven ultrasound guided SGBs on alternate days. Results: There was no significant difference between the two groups with respect to visual analogue scale score, edema, or overall patient satisfaction. After 1.5 months follow-up, however, the group that received methylprednisolone had better improvement in range of motion. No significant side effects were seen with either drug. Conclusions: The use of additives, both methylprednisolone and clonidine, is safe and effective for the SGB in CRPS. The significantly better improvement in joint mobility with methylprednisolone suggests that it should be considered promising as an additive to local anaesthetics when joint mobility is the concern.

현재 미국, 호주, 북유럽 등지의 해외 조경실무에서 BIM의 필요성에 대한 자각과 함께 전문적 연구가 수행되고 있으며, 관련 단체에서도 조직적 활동을 펼침으로써 BIM을 활용한 조경 프로젝트들이 증가하는 추세다. 그러나 아직 국내 조경분야에서는 BIM 도입이 이루어지지 않고 있으므로, 본 연구에서는 BIM을 활용한 조경 프로젝트 사례를 조사, 분석하여 BIM 도입에 따른 효과와 활용방법을 논하고자 했다. 이를 위해 세 가지 BIM 도입효과인 설계업무의 효율성 향상, 협업 환경의 마련, 지형설계의 형태 구현을 보여주는 조경 프로젝트들을 선정하고, 이들을 대상으로 조경정보 구축, 3D 모델링 제작, 상호운용성 확보, BIM 모델의 시각적 활용이라는 네 가지 측면에서 BIM의 활용방법을 살펴보았다. 첫째, 조경정보 구축의 측면에서 사례들을 살펴본 결과, 시설물과 수목 등 상세한 조경요소들로부터 기반시설 등 광범위한 건설정보들이 3D 라이브러리나 2D CAD 형식으로 구축되었다. 둘째, 3D 모델링 제작을 살펴보면 간단한 지형과 수목을 포함한 조경공간을 Revit으로 모델링하거나, 정교하고 복잡한 지형을 Maya와 같은 전문적 3D 모델링 도구로 모델링했다. 그리고 통합모델은 분야별 모델을 제작하여 주기적으로 교환, 검토하고, 최종적으로 이들을 통합하는 방식으로 제작되었다. 셋째, 분야간 데이터의 상호운용성은 파일 포맷의 단일화, 상이한 포맷의 변환, 또는 정보 표준의 준수를 통해 이루어졌고, 이를 토대로 건설정보를 공유하여 협업을 도모했다. 넷째, 3D 모델을 시각화함으로써 참여자들간의 의견조율, 설계안의 인허가, 대중 홍보가 이루어졌다. 사례분석을 통해 BIM은 디자인 도구라기보다 설계업무의 효율성을 높이고, 분야간 협업을 도모하는 프로세스임을 알 수 있었고, 특히 조경가들이 BIM을 활용한 통합 프로젝트에서 중요한 역할을 수행하고 있음을 확인했다. 따라서 그간 건설분야에서 BIM으로의 전환을 통해 많은 이익과 기회를 누렸듯이 조경분야에서도 적극적으로 BIM을 도입해야 할 것이다.

Objective: Extrauterine formation of decidua of stromal cells has been well described, particularly in the cervix and ovary. The apparent hormonal mechanisn of this phenomenon suggestes a relationship to endometriosis. Whether formation of ectopic decidua represents a marked progestational response of endometriosis or an independent peritoneal-stromal reaction to pregnancy is unclear. This study was designed to determine the prevalence of deciduosis in the patients whose fertility were proven. Design: Prospective study of patients who had undergone cesarean delivery without history of endometriosis. Materials and Methods: The study was performed in 179 full tenn pregnant women. During the cesarean section, the pelvic organs were thoroughly investigated and the biopsies were collected at the lesions suspicious endometriosis. And then microscopic examination of removed tissues were done. Results: Of the 179 patients who underwent cesarean delivery, 48 women (26.8%) had the lesions suspicious endometriosis such as adhesion, pigmented spots. The ovary was the most frequently ocurred site (79.2%). Microscopically, decidual cells were observed in 34 cases (70.8%) of 48 biopsed patients. Conclusion: Endometriosis has been known to be associated with subfertility. Our observations found the prevalence of deciduosis was 19.0% (34/179) in tenn pregnant women whose fertilites were proven. We suggests that the deciduosis maya manifestation of endometriosis during pregnancy. However, further follow up study should be done to confirm this clinicopathologic process.

목 적：본 연구의 목적은 주요우울장애환자를 대상으로 Heart Rate Variability(HRV) 검사를 이용하여 비침습적으로 자율신경계의 기능, 심혈관조절체계 및 항상성을 측정하여 정상대조군과 비교해보고 생리학적, 임상적 의미를 고찰해보는 것이다. 방 법：DSM-Ⅳ의 진단기준에 의하여 주요우울장애로 진단받은 환자 30명과 정상대조군 30명을 대상으로 하였다. 검사는 SA-2000E 기기를 사용하여 HRV parameter를 측정한 후 시(time) 영역과 주파수(frequency)영역별로 분석하였다. 결 과：Heart rate(HR)는 환자군에서 유의하게 증가된 소견을 나타내었으며 the standard deviation of the NN interval(SDNN), the root square of successive differences(RMSSD)도 환자군에서 유의하게 낮은 소견을 보였다. Total power(TP) band, very low frequency(VLF：$0.003{\sim}0.04\;Hz$) band, low frequency(LF：$0.04{\sim}0.15\;Hz$) band, high frequency(HF：$0.15{\sim}0.4\;Hz$) band는 환자군에서 유의하게 낮은 수치를 보였고, LF/HF의 비는 유의한 차이를 나타내지 않았다. 결 론：우울증 환자는 심박수의 증가와 HRV의 감소를 보였으며, 교감 신경과 미주 신경의 불균형이 높은 심혈관계 사망률과 부분적으로 연관이 있는 것 같다. 우울증 환자들은 심장에서 자율신경기능의 이상을 나타내며 이렇게 교감/부교감 신경활성 조절능력이 저하되어 균형이 깨짐으로써 높은 심혈관계 사망률을 보인다고 할 수 있다.
