Purpose: Nipple reconstruction is an important step in breast reconstruction after mastectomy. There are considerable number of reconstructive methods developed over the past years. Each of these has not only its own special advantages, but also limitations. Therefore, no single method has become the overwhelming favorite. Sometimes it seems to be compromised when the nipple must be located directly over a linear scar. Methods: A 48-year-old female patient received a central lumpectomy with circumareolar resection of the nipple areolar complex 4 months ago. The newly designed nipple must be positioned directly astride a scar. We drew two equal-sized rectangular flaps sharing a common limb on a transverse scar and the result was two opposing plow form. Each flap size was about 1.3 cm wide and 2.5 cm long. First we elevated the flap from the distal part at a deep dermal plane, then deepened the level of dissection to raise the dermal-fat flaps. The donor site could be closed directly without any dog-ear deformity. Then we folded down the elevated flaps and loosely sutured skin with nonabsorbable materials. Each flap inner side was approximated side by side. Finally we made new natural nipple with 6 mm projection. We applied tattooing in the areola area with micropigmentation device after three months. Results: After ten months of follow-up periods, the nipple projection was stable and symmetric. The nipple projection was 3.1 mm, compared with 2.8 mm for the opposite nipple. Conclusion: Our experiences shows that this double opposing plow flap is a particularly useful and simple technique when there is a traverse scar crossing the center of the proposed nipple area.

The analysis of outdoor and indoor spatial composition with natural elements is required for the creation of healing environment in healthcare facility to provide basic data for the planning of hospital architecture. Literature review of healing environment and investigation on characteristics of spatial composition in architectural works and healthcare facilities have been conducted. The spatial composition of outdoor space for refuge and prospect from indoor space of Seoul National University Hospital have been analyzed. The result of this research can be summarized as followed. First of all, the main natural elements for healing environment are consisted with refuge in outdoor space and prospect from indoor space. The second one is that natural elements in Seoul National University Hospital are located in central, posterior, and lateral area of main hospital and connectivity, integration, and ERAM(3) which the characteristics of outdoor spatial composition with space syntax are focused on the museum of medicine and landscape area in the center of hospital. The third one is that the outdoor refuge and prospect from indoor space in Seoul National University Hospital can be replaced with cultural heritage like the site of Kyungmogungji and Changgyeonggung palace in and next to the hospital. In addition to the outdoor and indoor spatial composition, it is necessary to analyze the relationship between elements to develop the healing environment of hospital architecture.

The study was performed to compare the dissolution, diffusion and absorption characteristics using Sartorius dissolution and absorption simulator and in vivo bioavailability of commercially available rifampicin capsules. Both brands C and F showed similar dissolution patterns and absorption properties through artificial gastric barrier in Sartorius simulator. Diffusion rate constants through the membrane of brands C and F were $3.04\;{\times}40^{-3}$ and $2.88\;{\times}\;10^{-3}cm/min$, respectively. Rifampicin capsules were administered orally to six fasted healthy volunteers according to cross-over design. The pharmacokinetic parameters between brands C and F, maximum plasma drug concentration$(C_{max})$, the time to reach $C_{max}$, absorption rate constant and area under the curve $(AUC_{0-24hr})$, elimination rate constant, and amount of drug excreted in urine were 6.11 and $7.27\;{\mu}g/ml$, 2.71 and 1.52 hr, 0.6371 and $1.6456 hr^{-1}$, 57.84 and $57.28\;{\mu}g\;{\cdot}\;hr/ml$, 0.1891 and $0.1734 hr^{-l}$, 119.98 and 119.93 mg, respectively. On the basis of experimental results, it was concluded that the bioavailability of brand C rifampicin capsules was almost the same as that of brand F rifampicin capsules.

This study is to enhance the provincial leisure plans through various programs and infrastructure facilities and to establish a network of natural leisure areas in Gyeonggi-do. According to the result, first, in terms of analyzing the locations of natural leisure areas by types, the rest of urban parks is formed in the Capital area outside Seoul as centering around the central area. Moreover, with regard to the rest of forest and the rest of natural ecology learning, the area of the detention exceeds the total area of Gyeonggi-do. The rest of valleys and swamps showed a dotted pattern of the detention area while the rest of tideland and fishing village experience indicated a distribution of the detention area along the West Coast as an axis. Second, according to result of analyzing the accessibility of natural leisure areas by types, the rest of valleys and swamps showed the highest accessibility among the natural leisure areas : the rest of natural ecology learning had the medium level of accessibility; the rest of forest indicated the lowest accessibility. Therefore, it is necessary to create more leisure areas concerning the futures demands. In addition, they should be constructed in the places adjacent to the urban district area exhibiting higher usability and accessibility. In the places where there are many natural leisure area with higher utility, management plans should be deliberated as well. Based on the result of analyzing the rest of valleys and swamps and the rest of tideland and fishing village experience, it was found that the natural leisure area should improve the quality of water intensively and hydrophile property and create hydrophilic spaces. The development of natural leisure areas need to be carried out under the principle of environmental protection while considering historic sites and nearby rivers and lakes. Moreover, water leisure programs should be developed actively as well with further utilization of water resources in order to enhance the usability of natural leisure.

본 연구는 한국 온대중부지역 소나무림 군락식재 모델을 제시하기 위해 충청남도 당진군 일대 소나무림을 대상으로 다양한 경급의 소나무림을 조사하였다. 유령림부터 장령림까지 총 $10{\times}10m(100m^2)$의 방형구 92개소를 설치하고, 출현개체별 규격을 모두 조사하였으며, 개체간 생육거리 분석을 위해 44개 조사구에 대해서는 1/100 scale로 교목층과 아교목층 수목의 위치를 조사하였다. 분석결과, 모든 조사구의 교목층은 양호하게 발달해 있었으나, 아교목층의 흉고단면적이 교목층의 10%에 미치지 못하고 있었으며, 관목층의 경우 일정한 피복율을 보이지 않고 조사구마다 매우 다양하였다. 이에 소나무 군락식재는 교목층과 관목층의 구조로 조성하는 것이 바람직한 것으로 판단되었으며, 관목층의 경우에는 특정 경향이 없어 식재하려는 인접 지역의 소나무림을 별도로 조사하여 적용하는 것이 바람직한 것으로 판단되었다. 군락식재 모델을 위한 소나무 교목층 흉고직경급별 단위면적당 생육개체수 및 단위면적당 생육개체수와 생육수목간 최단거리와의 회귀식은 높은 설명력을 보였다.

Elemental dry deposition fluxes were measured using dry deposition plates from March to June 1998 in Seoul, Korea. During this spring sampling period several yellow sand events characterized by long-range transport from China and Mongolia impacted the area. Understanding the impact of yellow-sand events on atmospheric dry deposition is critical to managing the heavy metal levels in the environment in Korea. In this study, the measured flux of a primarily crustal metal, Al and an anthropogenic metal, Pb was used with two hybrid receptor models, potential source contribution function (PSCF) and residence time weighted concentration (RTWC) for locating sources of heavy metals associated with atmospheric dry deposition fluxes during the yellow-sand events in Seoul, Korea. The PSCF using a criterion value of the 75th percentile of the measured dry deposition fluxes and RTWC results using the measured elemental dry deposition fluxes agreed well and consistently showed that there were large potential source areas in the Gobi Desert in China and Mongolia and industrial areas near Tianjin, Tangshan, and Shenyang in China. Major industrial areas of Shenyang, Fushun, and Anshan, the Central China loess plateau, the Gobi Desert, and the Alaskan semi-desert in China were identified to be major source areas for the measured Pb flux in Seoul, Korea. For Al, the main industrial areas of Tangshan, Tianjin and Beijing, the Gobi Desert, the Alashan semi-desert, and the Central China loess plateau were found to be the major source areas. These results indicate that both anthropogenic sources such as industrial areas and natural sources such as deserts contribute to the high dry deposition fluxes of both Pb and Al in Seoul, Korea during yellow-sand events. RTWC resolved several high potential source areas. Modeling results indicated that the long-range transport of Al and Pb from China during yellow-sand events as well as non yellow-sand spring daytimes increased atmospheric dry deposition of heavy metals in Korea.

On the basis of 2017, the cremation rate in capital area was 89.0% which was much higher than the national average cremation rate(84.6%). Due to the short supply of cremation facilities in accordance with the increased number of cremation cases every year, the demand for cremation from the residents outside of the jurisdiction area with no cremation facilities was increased, so that the residents in the jurisdiction area had difficulties in using the Online Cremation Reservation Service in Funeral Information System. Thus, this study aims to make suggestions for policies as follows.First, on the basis of 2017, the demand-supply rate of cremation facilities in Gyeonggi-do was 139.4%, which means that the demand for cremation largely exceeds the ability to supply cremation. Therefore, first, in the level of Gyeonggi-do, the expanded supply of cremation facilities should be induced by carrying forward policies such as financial support to the basic local governments installing cremation facilities and expansion of incentives support to the residents of regions attracting cremation facilities. Second, it would be necessary for the central government to expansively conduct the support standard price and government subsidy rate(70%) for the new construction of cremation facilities and the establishment of cremation furnaces. Third, there should be some policies to decrease the inflow of residents outside of the jurisdiction area by raising the fee for using cremation facilities outside of the jurisdiction area of Seoul Metropolitan City and also expanding the application of a sliding scale of cremation hours.

Yongsan ward is located at central place connecting south and north ecology axis of seoul. Various environment-friendly Yongsan development could pose positive effects on NPS(non pollutant source) pollutant reductions and water quality improvement at Han-rive because BOD, T-N, and T-P NPS discharges took 90% of total pollutant from this area. In this study, direct runoff and NPS pollutant loads were evaluated before and after development using spatio-tamporal change in CN(curve number) and EMC(event mean concentration) data. It was found that direct runoff value is $23,584,724m^3$, and BOD, T-N and T-P loads are 104,456 kg/year, 111,483 kg/year and 7,500 kg/year under pre-development condition, respectively. Annual runoff, BOD, T-N and T-P reducing rate were 12.9%, 33.3%, 35.6% and 40.7% under integrated post-development condition, respectively. Based on the results obtained in this study, environment-friendly urban development could be achieved at Yongsan area.

본 논문은 지속적인 서울시의 성장이 그 주변지역의 성장을 수반하면서 서울대도시 권화되어가는 과정을 밝히고 서울대도시권역을 설정한 후, 서울대도시권역 내에서 기능적 특성에 따라 지역을 분류하려는 것이 그 목적이었다. 1990년 시점에서의 서울대도시권역의 경계가 어느 정도 확대되었는가를 측정하기 위하여 도시화 정도를 측정하는 지표와 서울과 의 기능적 연계성을 측정하는 지표를 토대로 하여 그 권역을 설정하였다. 그 결과 서울대도 시권역은 수도권의 거의 전 지역을 포함하고 있는 것으로 나타났다. 또한 서울대도시권역에 포함된 지역들은 서울이 갖고 있는 기능을 일부 분담하면서 기능적인 면에서 특화되거나 전 문화되어 기능적 특성에 따라서 신종주거기능 탁월지역, 제조업기능 탁월지역, 서비스기능 탁월지역, 잠재적 개발가능지역의 4개 그룹으로 지역을 분류할 수 있었다.
