The purpose of this study is to analyze protection functionality of supermodern fashion which is shown by responding to supermodern environment, where non-spaces increases in the 21st modern city. The theoretical background is drawn for supermodern environment theory. For the study, he researcher used existing study and specialized book and analyzed photograph materials by selecting them in specialized fashion book, internet site and designer's collection. The works from 1995 S/S collection to 2008 S/S collection are analyzed. The result of this study is as follow. First, supermodern design is adopting the shape of high-functional element, electronic device, protective device to protect wearer in non-space. Second, in order to mentally protect individual anonymous leadership of interaction is granted by adopting hood, veil or mask. Third, supermodern design is creating independent and user-based space by shape transformation in change of urban environment. Fourth, in order to protect wearer through camouflage or concealment, camouflage pattern or neutral color are used.

To establish a monthly data collection planning for the Ocean Scanning Multispectral Imager (OSMI), we have examined the global patterns of three impacting factors: pigment concentration, cloud cover, and sun glint. Other than satellite mission constraints (e.g., duty cycle), these three factors are considered critical for the OSMI data collection. The Nimbus-7 Coastal Zone Color Scanner (CZCS) monthly mean products and the International Satellite Cloud Climatology Project (ISCCP) monthly mean products (C2) were used for the analysis of pigment concentration and cloud cover distributions, respectively. And the monthly simulated patterns of sun glint were produced by performing the OSMI orbit prediction and the calculation of sun glint radiances at the top-of-atmosphere (TOA). Using monthly statistics (mean and/or standard deviation) of each factor in the above for a given 10$^{\circ}$ latitude by 10$^{\circ}$ longitude grid, we generated the priority map for each month. The priority maps of three factors for each month were subsequently superimposed to visualize the impact of three factors in all. The initial results illustrated that a large part of oceans in the summer hemisphere was classified into the low priority regions because of seasonal changes of clouds and sun illumination. Sensitivity tests were performed to see how cloud cover and sun glint affect the priority determined by pigment concentration distributions, and consequently to minimize their seasonal effects upon the data collection planning.

The objective of this study was to evaluate particle collection performance of electrostatic precipitator (ESP) integrated with double skin façade in naturally ventilated residential buildings using numerical method. To evaluate the efficiency, computational fluid dynamics (CFD) simulation based on electric potential and Lagrangian method was applied. The CFD model was validated by comparing the simulated results with the experimental data including thermal characteristic of double skin façade (DSF) and particle removal characteristic of electrostatic precipitator. The validation results showed that the root mean square error (RMSE) between predicted values and measured values of velocity and temperature in intermediate space of DSF was 1.2%. The adequacy of ion space charge density and turbulent model were determined. The RMSE between predicted values and measured values of collection efficiency of ESP was 9.2%. In addition, the case study was performed to present the application of the numerical method based on validation results of ESP integrated with façade.

The author devotes this paper to defining a new class of generalized soft open sets, namely soft somewhere dense sets and to investigating its main features. With the help of examples, we illustrate the relationships between soft somewhere dense sets and some celebrated generalizations of soft open sets, and point out that the soft somewhere dense subsets of a soft hyperconnected space coincide with the non-null soft ${\beta}$-open sets. Also, we give an equivalent condition for the soft csdense sets and verify that every soft set is soft somewhere dense or soft cs-dense. We show that a collection of all soft somewhere dense subsets of a strongly soft hyperconnected space forms a soft filter on the universe set, and this collection with a non-null soft set form a soft topology on the universe set as well. Moreover, we derive some important results such as the property of being a soft somewhere dense set is a soft topological property and the finite product of soft somewhere dense sets is soft somewhere dense. In the end, we point out that the number of soft somewhere dense subsets of infinite soft topological space is infinite, and we present some results which associate soft somewhere dense sets with some soft topological concepts such as soft compact spaces and soft subspaces.

액체질소 보존법은 동결 건조 보존이 불가능한 것을 포함한 곰팡이를 가장 효과적으로 보존할 수 있는 방법 중의 하나로서, 유전적인 변화와 오염을 방지하고 장기보존이 가능한 이점을 가진다. 크료튜브 대신 액체질소 보존에 사용할 수 있는 폴리프로필렌 스트로는 경제성, 안전성, 편리성 그리고 공간 이용성 등의 이점을 가진다. 이에 한국농업미생물자원센터(KACC)에서는 폴리프로필렌 스트로를 이용한 곰팡이의 액체질소 보존법을 정립하였으며, 이를 상세하게 소개하였다.

서울특별시 자치구의 공공도서관 확충은 2004년 4개관에서 2009년 15개관으로 해를 거듭 할수록 지속적인 증가 추세를 보여주고 있다. 이와 반대로 신규로 확충되는 구립 공공도서관의 규모는 점차적으로 작아지는 경향을 보여주고 있다. 이러한 현상으로 구립 공공도서관들은 개관 후 수년이 지나면 증가하는 장서 규모를 수용하지 못하고 서가 공간 부족으로 인해 장서를 폐기하는 새로운 행태를 보이고 있다. 본 연구는 서울특별시 자치구에서 운영하고 있는 공공도서관의 장서 폐기 실태 조사를 통하여 장서 폐기 기준과 현황, 처리 방안을 기반으로 장서 폐기에 대한 개선 방안을 제언하였다.

Objective : Postoperative subgaleal cerebrospinal fluid (CSF) collection is considered as one of the common minor surgical complication which can lead to prolonged hospitalization. We introduce "galeal tack-up suture" to prevent postoperative subgaleal CSF collection. Methods : Galeal tack-up suture consists of various surgical techniques which aim to fix galea to cranium in order to prevent CSF pooling in subgaleal space. A total of 87 patients who underwent craniotomy were divided into two groups while closing the wound : group A with galeal tack-up suture and group B with routine wound closure without galeal tack-up suture. The patients were observed for postoperative subgaleal CSF collection. Results : Among 87 cranitomy cases, galeal tack-up suture was performed in 32 cases and routine wound closure was done in 55 cases. Postoperative subgaleal CSF collection occurred in 13 cases (15%) in which 12 cases occurred in group B patients and 1 case occurred in group A patients (p=0.026). Conclusion : Galeal tack-up suture is an easy and effective technique in wound closure to prevent postoperative CSF collection.

임베디드 시스템이 모놀리식(monolithic) 커널을 사용하면서, NAND 플래시 메모리는 가상 메모리 시스템의 스왑(swap) 공간을 위해 사용되고 있다. 플래시 메모리는 저전력 소비, 충격 내구성, 비 휘발성의 장점을 가지지만, '쓰기 전 삭제'의 특징 때문에 가비지 컬렉션(GC) 작업이 필요하다. GC 기법의 효율성은 플래시 메모리 성능에 큰 영향을 미친다. 본 논문에서는 플래시 메모리를 기반으로 하는 가상 메모리 시스템에서 메인 메모리와 플래시 메모리 사이에 중복된 데이터를 활용한 새로운 GC 기법을 제안한다. 제안된 기법은 GC 부하를 최소화하기 위해 데이터의 지역성을 고려한다. 실험 결과는 제안된 GC 기법이 이전의 기법과 비교하여 평균적으로 37%의 성능을 향상시킴을 보여준다.
