As activities and convenience of residents in outdoor spaces in apartment houses have been considered important, strategies for making outdoor spaces in apartment houses healing spaces have emerged as a major interest. The purpose of this study is to draw elements for planning healing to create healing spaces in collective housing areas and to present design guidelines. The findings of this study are as follows. Functional elements of a healing environment were classified into safe environment, therapeutic environment, ancillary environment, orientation-reinforcing environment, amenities, and social environment. Outdoor spaces in collective housing areas were divided into collective housing entrance areas, internal and external spread areas, outdoor activity areas, and areas by theme. First, collective housing entrance areas should be planned in such a manner that residents can feel the area is private and easy to recognize. Second, internal and external spread areas should be planned in such a manner that they are easy to access and communicate with neighbors. Third, outdoor activity areas should be divided into an open space, resting space, playing space, and sports space. Open spaces should be planned in such a manner that they can command a fine view and respect the privacy of nearby residents. Resting spaces should be equipped with a shelter that protects users from direct sunlight, rain, and snow as well as include a movable bench. Playing spaces should be built considering development of children's curiosity, adventurous spirit, character, stimulation, and physical health. Playing spaces should be designed in such a manner that roadways and sidewalks can be separated for safe traffic. Sport spaces should be planned in such a manner that they can be associated with a pavilion and trail that provide residents with an opportunity to communicate with each other and rest. Fourth, spaces by theme are classified into sense garden, therapeutic garden, experiential garden, and learning garden. Sense gardens are a small garden based on the five senses. Sense gardens should be designed in such a manner that they can improve users' mental and physical health through programs that stimulate the sense of sight, auditory sense, and olfactory sense. Therapeutic gardens should be designed in such a manner that they can provide a comfortable and relaxing space by minimizing noise. It is advisable for therapeutic gardens to be equipped with a medicinal herb garden, meditation garden, and sense garden. Experiential and learning gardens should be designed in such a manner that they can provide users with a space in which they can enjoy nature and leisure activities. It is advisable for experiential and learning gardens to be equipped with a tea garden, vegetable garden, and camping garden. Healing programs should be designed in such a manner that users can feel relaxed by providing a healing environment, making the most of the natural environment. Further research on evaluating whether the findings of this study are effective in healing in a qualitative and quantitative manner is needed. 본 연구는 공동주택단지를 대상으로 하여 외부의 조경공간을 통해 치유환경을 제공하여 치유기능을 높이기 위한 조경계획방안을 제시하고자 한다. 본 연구를 통해 지속적으로 늘어나고 있는 집합주거공간의 외부공간 조성에 있어 거주민들에게 생활환경을 높일 수 있는 기회와 함께 조경설계기법의 대안적인 기준을 마련한다는 점에서, 정형화되어 있지 못하고 있는 조경설계 분야의 새로운 가이드라인을 제공하는데 그 의미가 있다. 연구 방법으로는 기존 학자들의 치유정원에 관한 특성을 분석하여 공통적인 환경특성 요소들을 도출하고, 이를 바탕으로 기존 국내 외 문헌을 통하여 세부항목을 설정하며, 선행연구와 사례조사, 설문분석을 통해 치유조경계획 요소를 도출하였다. 치유환경의 기능적 계획요소 6가지 항목을 설정하였다. 안전한 환경, 치료적 환경, 보조적 환경, 지남력 강화환경, 쾌적성, 사회적 환경으로 구분하였고, 공간계획요소는 국내 외 사례고찰로 병원, 요양원, 숲 등을 대상으로 하여 육체적, 정신적 안정에 도움을 주기 위한 공간 및 시설을 도입하고 있는 것을 알 수 있었다. 계획요소로 공간계획, 동선계획, 포장계획, 수경계획, 식재계획, 시설계획, 프로그램으로 구분하여 계획요소를 도출하였다. 도출된 항목을 외부공간의 단지출입 영역, 내 외부 전이영역, 외부활동 영역, 테마별 공간영역으로 구분하고, 계획 요소로 공간계획에는 자연속 산책이 가능하고, 범죄로부터 안전, 다양한 휴게시설이 있도록 계획한다. 식재계획으로는 계절감을 느낄 수 있는 수목 식재, 촉각 미각, 후각을 자극하는 식물 식재, 풍부하고 다양한 식물 식재로 계획한다. 동선계획은 외부로부터 동선을 분리하고, 건강증진을 위한 산책, 지압로, 흙길 등 자연감상이 가능한 동선으로 계획한다. 포장계획은 위험에 쉽게 인식할 수 있고, 인공재료보다는 자연형 재료로 계획한다. 시설물계획은 취약계층을 위한 안내표, 강설시에도 이용할 수 있도록 쉘터 및 이동 가능한 벤치를 계획한다. 수 공간계획은 잔잔한 물 공간을 조망하는 사색 가능한 물시설과 분수 등 깔끔하고 도식적인 물시설로 계획한다. 치유프로그램으로는 휴식 명상을 취할 수 있으며, 요가, 산책 등 가벼운 운동을 위한 프로그램을 계획한다. 치유조경계획 요소를 도출하여 가이드라인을 제시하였으나, 계획요소와 계획내용들이 치유기능을 향상시키는데 효과가 있을지에 대한 정성적, 정량적 평가가 제한되어 이에 대한 연구가 추후 이루어질 필요가 있다.

Resolvin D5, a Lipid Mediator, Inhibits Production of Interleukin-6 and CCL5 Via the ERK-NF-κB Signaling Pathway in Lipopolysaccharide- Stimulated THP-1 Cells

One of the omega-3 essential fatty acids, docosahexaenoic acid (DHA), is a significant constituent of the cell membrane and the precursor of several potent lipid mediators. These mediators are considered to be important in preventing or treating several diseases. Resolvin D5, an oxidized lipid mediator derived from DHA, has been known to exert anti-inflammatory effects. However, the detailed mechanism underlying these effects has not yet been elucidated in human monocytic THP-1 cells. In the present study, we investigated the effects of resolvin D5 on inflammation-related signaling pathways, including the extracellular signal-regulated kinase (ERK)-nuclear factor (NF)-κB signaling pathway. Resolvin D5 downregulated the production of interleukin (IL)-6 and chemokine (C-C motif) ligand 5 (CCL5). Additionally, these inhibitory effects were found to be modulated by mitogen-activated protein kinase (MAPK) and NF-κB in lipopolysaccharide (LPS)-treated THP-1 cells. Resolvin D5 inhibited the LPS-stimulated phosphorylation of ERK and translocation of p65 and p50 into the nucleus, resulting in the inhibition of IL-6 and CCL5 production. These results revealed that resolvin D5 exerts anti-inflammatory effects in LPS-treated THP-1 cells by regulating the phosphorylation of ERK and nuclear translocation of NF-κB.

This study is aimed to find ways to analyze the current nighttime use of mountainside Mt.Bomunsan Park and thereby, to increase the efficiency of mountainside parks situated in urban areas, by case-studying other similar parks whose nighttime use has been facilitated. Also, the study focused on identifying diverse leisure activities for urban citizens to enjoy at night at such parks. First, the Mt.Boumunsan Park area was analyzed in its current nighttime use, space by space, to learn how the park is used by the public at night. Second, other parks whose physical environment is similar to that of Mt.Boumunsan Park were case-studied so that the result could be reflected on the operation of Mt.Boumunsan Park. Third, revitalization suggestions were made for the visit to Mt.Boumunsan Park during nighttime so that they can be referred to as basic data when planning and designing a park in the future for more efficient spacing. It is anticipated that when planning and designing is under consideration to improve Mt.Boumunsan Park, it is better to devise, after taking into account the local government's financial status and the public opinions, a short-and mid-term plan will better serve citizens than a non-feasible long-term master plan.

윤태일,천현우,김창우,최효섭 대한산업공학회 2021 대한산업공학회 추계학술대회논문집 Vol.2021 No.11

데이터 수집 시스템은 데이터 수집뿐만 아니라 수집된 데이터를 가공하고 데이터를 저장하는 과정, 추가적으로 수집된 데이터가 잘 처리되고 있는지 확인할 수 있는 모니터링 시스템을 포함한다. 이러한 데이터 수집 시스템을 설계하기 위해서는 구체적인 데이터 흐름의 파악과 전반적인 아키텍처 설계를 알고 있어야 하는 단점이 있기에 본 논문에서는 산업통신분야에서 일반적으로 사용되는 통신프로토콜인 Modbus TCP로 태양광 ESS 시스템에서 데이터 수집 시스템을 설계하는 것에 목적을 두었다.

Kanakugiol, a Compound Isolated from Lindera erythrocarpa, Promotes Cell Death by Inducing Mitotic Catastrophe after Cell Cycle Arrest

A novel compound named ‘kanakugiol’ was recently isolated from Lindera erythrocarpa and showed free radical-scavenging and antifungal activities. However, the details of the anticancer effect of kanakugiol on breast cancer cells remain unclear. We investigated the effect of kanakugiol on the growth of MCF-7 human breast cancer cells. Kanakugiol affected cell cycle progression, and decreased cell viability in MCF-7 cells in a dose-dependent manner. It also enhanced PARP cleavage (50 kDa), whereas DNA laddering was not induced. FACS analysis with annexin V-FITC/PI staining showed necrosis induction in kanakugiol-treated cells. Caspase-9 cleavage was also induced. Expression of death receptors was not altered. However, Bcl-2 expression was suppressed, and mitochondrial membrane potential collapsed, indicating limited apoptosis induction by kanakugiol. Immunofluorescence analysis using α- tubulin staining revealed mitotic exit without cytokinesis (4N cells with two nuclei) due to kanakugiol treatment, suggesting that mitotic catastrophe may have been induced via microtubule destabilization. Furthermore, cell cycle analysis results also indicated mitotic catastrophe after cell cycle arrest in MCF-7 cells due to kanakugiol treatment. These findings suggest that kanakugiol inhibits cell proliferation and promotes cell death by inducing mitotic catastrophe after cell cycle arrest. Thus, kanakugiol shows potential for use as a drug in the treatment of human breast cancer.
