Purpose: This paper is a review of interventions designed to promote self-awareness in the nursing area. The specific purpose was to analyze the general characteristics of self-awareness intervention studies, intervention contents, and the effects of the studies in order to present basic information for developing self-awareness interventions in the nursing area. Methods: Using "nurse/nursing" and "self-awareness" as key words, the researchers searched six electronic databases. The method proposed by Whittemore and Knafl was used. Results: Seventeen studies met the inclusion criteria. The most common research design was quasi-experimental. Nine quasi-experimental studies (52.9%), 7 qualitative studies (41.2%), and 1 mixed methodology study (5.9%) were analyzed. Most studies used group intervention and student nurses as participants. The interventions were revealed to be effective in enhancing participants' self-awareness. The reflection method was used in most intervention approaches. Conclusion: To provide therapeutic nursing care, having self-awareness is important. Future research with well-designed clinical trials applying self-awareness intervention needs to be conducted to enhance self-awareness in the nursing area.

The 21st century is currently undergoing an era of urban regeneration. The purpose of this research is to secure and expand the green infrastructure with zoning regulation in the context of urban regeneration. This objective also seeks a way of urban regeneration through the use of existing large parks by employing park-based mixed use districts around the periphery of large urban parks and green spaces. This research examines the limits, problems of existing single- and mixed-use zoning districts for securing of green infrastructure by book review. This research finally advocates introducing a another type of urban mixed-use districts, namely park-based mixed use district and its characteristics and functions, by using landscape ecology and landscape urbanism as a theoretical basis. The results of this research suggested that large parks and green spaces should be considered as one of patch in landscape ecology. This research also discusses the possibility that, as patches have ecotones with greater biodiversity in the peripheral areas of it, the green infrastructure can be constructed around the periphery of large urban large parks and green spaces by introducing cultural ecotone of nature's convergence with the city. As a result, the green infrastructure and high density of land use and using behaviour can be increased. Park-based mixed use districts encourage the convergence of parks and the city, with the park being used as the main function; residential, commercial, business and cultural uses etc. are partial functions. In order for the park-based mixed use districts to be designated, the size of large urban parks and green spaces, as well as location, city function and condition of the peripheral areas all need to be considered. The necessity to examine the designated width of the park-based mixed use districts and the form of the peripheral area was also discussed. This research, which is based on investigative research results, suggests that further in-depth and comprehensive analysis of the actual condition of urban large parks and peripheral areas needs to be completed. Specialists and other interested parties, analysis and investigation on related plans and designs are also needed for the institutional practice.

장기간 시행된 새만금 건설단계별 환경변화 분석을 위해 3차원 무작위 행보에 의한 입자추적 기법을 이용한 해석이 시도되었다. 방조제 공사로 만경 동진강 및 금강 하구역의 운동 양상이 크게 변화되었다. 변산반도 외해 부근 운동 감소와 호 내 북측구간의 흐름 정체가 특이하다. 조류 이동거리를 건설단계별로 평가한 결과도 유사한 결과를 보인다. 연직혼합형태의 변화 분석을 위해 수온, 염분을 고려한 밀도성층을 재현한 결과 방조제 착공 전 잘 혼합된 연직구조 형태는 공사 중 개방구간 존재 시 부분적으로 혼합된 구조로 변화되고, 완공 후에는 만경 동진강 하구 입구부에 염분쐐기 구역과 호소 측에는 강한 밀도성층이 발생한다. 해석결과 수평방향의 확산과 연직 방향의 혼합능력 감소로 새만금 내외측 수질환경에 부정적 영향으로 작용할 수 있음이 추론된다.

천수만 황도 갯벌의 IKONOS 영상을 이용한 표층 퇴적상 분류를 위하여 광학 반사도를 입도, 조류로의 형태, 지잔존수 (surface remnant water)의 면적비와 같은 다양한 퇴적환경 요소들과 비교하였다. IKONOS 영상과 갯벌 내의 소지형별 퇴적환경 사이의 관계를 분석하기 위하여 Echo-sounder를 이용하여 갯벌 Digital Elevation Model (DEM)을 만들었다. 펄-혼합 퇴적상과 모래 퇴적상의 경계에서 광학 반사도의 차이가 뚜렷하게 나타났으며 사주의 구분도 가능하였다. 펄-혼합 퇴적상 지역은 조류로가 매우 복잡하게 발달하고 있으며 지형이 상대적으로 높은 곳에 위치하고 있었다. 펄과 혼합 퇴적의 경계에서 지표수의 존재 유무가 다르게 나타났으나 광학 반사도의 차이가 뚜렷하지 않았다. 모래 퇴적상의 경우 조류로가 단순하게 직선형으로 발달했으며 지형도 상대적으로 낮은 지역에 분포하였으며 지표잔존수가 거의 전 지역을 덮고 있어 광학 반사도가 낮게 나타났다. 최대우도 분류법을 이용한 표층 퇴적상 분류정밀도는 86.2 %로 나타났다. 이 결과로부터 IKONOS와 같은 고해상도 영상에 대해 지표잔존수, 조류로 분포와 지형 등의 갯벌 퇴적학적 특성을 고려한다면 펄, 혼합 그리고 모래 퇴적상 구분은 가능하다는 것을 알 수 있다.

In the thin film alloy formation of the transition metals ion-beam-mixing technique forms a metastable structure which cannot be found in the arc-melted metal alloys. Sppecifically it is well known that the studies about the electronic structure of ion-beam-mixed alloys pprovide the useful information in understanding the metastable structures in the metal alloy. We studied the electronic change in the ion-beam-mixed ppt-Ct alloys by XppS and XANES. These analysis tools pprovide us information about the charge transfer in the valence band of intermetallic bonding. The multi-layered films were depposited on the SiO2 substrate by the sequential electron beam evapporation at a ppressure of less than 5$\times$10-7 Torr. These compprise of 4 ppairs of ppt and Cu layers where thicknesses of each layer were varied in order to change the alloy compposition. Ion-beam-mixing pprocess was carried out with 80 keV Ae+ ions with a dose of $1.5\times$ 1016 Ar+/cm2 at room tempperature. The core and valence level energy shift in these system were investigated by x-ray pphotoelectron sppectroscoppy(XppS) pphotoelectrons were excited by monochromatized Al K ａ(1486.6 eV) The ppass energy of the hemisppherical analyzer was 23.5 eV. Core-level binding energies were calibrated with the Fermi level edge. ppt L3-edge and Cu K-edge XANES sppectra were measured with the flourescence mode detector at the 3C1 beam line of the ppLS (ppohang light source). By using the change of White line(WL) area of the each metal sites and the core level shift we can obtain the information about the electrons pparticippating in the intermetallic bonding of the ion-beam-mixed alloys.

Contemporary shops play an important role as a place to experience contemporary culture as well as sales and display techniques. This study is to suggest one of the prototypes of character streets consisting of characteristic shops through the analysis of the stores in the SoHo area in New York City. The study found that there are three kinds of characteristic shops preserving the cast-iron architectural environment in the SoHo area. In the first case, the interiors of the shops are partially renovated original lofts keeping decorative columns, white plaster walls and wooden floors. In the second case, the interiors are totally renovated leaving no old traces. This is achieved through wrapping columns and replacing old materials with new ones. In the third case, the interiors are renovated with the different approaches using mixed ideas and materials. The original columns exist but are transformed in this case. In the third case, shops tend to be extra large and complicated. The Prada shop in SoHo by Rem Koolaas is the best example of this case. This shop is the conceptual city, theater and avant-garde museum itself, that is, the place of experiencing contemporary culture.

Two unidentified methanotrophic strains (MM-white and MM-red) secreting soluble methane monooxygenase (sMMO) involved in thrichloroethylene biodegradation have been isolated from mixed methanotrophic consortium (MM) around Taejon area. Subsequently four methanotrophic strains were isolated from MM and named according to their color; white (MS-white), yellow (MS-yellow), pink (MS-pink) and reddish brown (MS-rbrown). All strains except MS-yellow which can take glucose as well as methane, metabolized methane as a sole carbon source. They all showed symbiotic behavior when methane was used as the sole carbon source. Optimum conditions of cell growth for MM were pH of 6.8 - 7.2, temperature of 29 - 32$^{\circ}C$, and gas flow rate of 6 (for methane), 40 (for air), and 4 ml/min (for carbon dioxide). The sMMO activity was expressed as naphthalene oxidation rate (${\mu}$mol/ mg protein/ hr). The sMMO activity for MM grown in flask culture with 1 ${\mu}$M of CuSO4 was 36, while it was 61 without copper. The activity for MM grown in the fermentor without CuSO4 was 1077, but is was 197 after reaction with 5 ppm of TCE. The methanotrophs showed significantly high sMMO activity despite the presence of 1 ${\mu}$M of CuSO4, although most of other strains already known could not express sMMO activity under this condition.

Heavy rainfall events are occurred exceedingly various forms by a complex interaction between synoptic, dynamic and atmospheric stability. As the results, quantitative precipitation forecast is extraordinary difficult because it happens locally in a short time and has a strong spatial and temporal variations. GOES-9 imagery data provides continuous observations of the clouds in time and space at the right resolution. In this study, an power-law type algorithm(KAE: Korea auto estimator) for estimating rainfall based on the rainfall type was developed using geostationary meteorological satellite data. GOES-9 imagery and automatic weather station(AWS) measurements data were used for the classification of rainfall types and the development of estimation algorithm. Subjective and objective classification of rainfall types using GOES-9 imagery data and AWS measurements data showed that most of heavy rainfalls are occurred by the convective and mired type. Statistical analysis between AWS rainfall and GOES-IR data according to the rainfall types showed that estimation of rainfall amount using satellite data could be possible only for the convective and mixed type rainfall. The quality of KAE in estimating the rainfall amount and rainfall area is similar or slightly superior to the National Environmental Satellite Data and Information Service's auto-estimator(NESDIS AE), especially for the multi cell convective and mixed type heavy rainfalls. Also the high estimated level is denoted on the mature stage as well as decaying stages of rainfall system.

Zoysiagrass has been used in Korea as a native grass. Informations on distributions, classifications, breeding efforts and outputs, current production and uses of zoysiagrasses in Korea are summarized. During past a few decades, collection of naturally growing zoysiagrass ecotypes has been continued, followed by evaluation, selection and cross-pollination. Classification efforts using important morphological, biochemical traits and DNA polymorphisms resulted in the several suggestions of grouping zoysiagrass species and varieties. Zoysia japonica consistently form separate group, while Zoysia sinica and Zoysia macrostackya have been separately or inter-mixed. Z. matrella with some variations frequently grouped separately but with some similarity with Z. tenuifolia, which was recently renamed as Z. pacifica. Hybrid types of zoysiagrasses were frequently found in Korea. New varieties such as 'Kunhee' and 'Green Ever' etc. were bred by ecotype selections, while 'Senock', 'Semil', 'Millock' were bred through pollination. Molecular approaches were also used to introduce beneficial genes into zoysiagrasses with no practical outputs by legal regulations. Currently popular varieties are inter-specific hybrid types such as 'Anyang' and other local zoysiagrasses as well as common zoysiagrass (Zoysia japonica) Production area in Korea was estimated as 2,947 ha with increasing problems of mixed or contaminated species and varieties.
