  • The aim of this study was to review previous literature to determine the effects of nature-based program for workers. This systematic review was conducted in accordance with National Evidence-based Healthcare Collaborating Agency's guidance for undertaking systematic reviews for intervention. Literature search was performed using National Assembly Digital Library, Korean Studies Information Service System, and Korea Education & Research Information Service for literature published until March 2019. The participants were full-time workers, and intervention of nature-based programs was conducted in the outdoor, indoor, and indirect nature contact exposures, with comparators in the control group who did not receive the treatment. The results showed that the programs were effective in physical, psychological, and social health. The methodological quality of randomized controlled trials (RCT) was assessed using the Cochrane Risk of Bias(RoB) tool, while non-randomized controlled trials (N-RCT) were assessed using the Cochrane Risk of bias assessment tool for non-randomized studuies (RoBANS). A total of 16 studies were selected for assessment: two RCTs, 10 N-RCTs, and four one-group pretest-posttest designs. Most interventions were provided at the workplace and in the community. There were many kinds of nature-based interventions, and forest therapy and horticultural therapy programs were most common. Various interventions for workers effectively improved job stress, depression, serum cortisol and stress-response. However, the included studies lacked methodological rigor. Future research is needed to evaluate the long-term effectiveness of nature-based programs for workers using rigorous research designs.

  • 현재 우리나라에 설치된 어도의 90% 이상이 콘크리트 인공 어도로 되어있으나, 최근 자연적인 재료를 이용하여 소하천의 형태로 설치하는 자연형 어도가 많이 설치되고 있다. 이에 따라 국내 정부산하 공기업과 대학에서는 자연형 어도에 대한 설계 기준에 등록할 목적으로 '자연형 어도 표준모형 형식(안)'을 제안하였다. 본 연구에서는 기존에 제안된 형식안을 검토해보고 보완, 개선되어야 할 사항을 제시해보았다. 연구 결과, 지금까지 국내에서 어도 설계와 관련하여 진행되었던 연구가 매우 부족해 적절한 기준을 마련하는데 한계가 있었던 것으로 판단된다. 특히 우회수로형 자연형 어도에서의 구조 유지 방안이나 내부 돌 설치 방법, 또는 자연 재료에 대한 연구가 부족한 것으로 판단되었는데, 이는 해외에서 진행되었던 연구사례에 비춰볼 때 국내에서도 국내 상황에 맞는 설계 연구가 보다 적극적으로 진행되어야 할 것으로 보인다. 또한 경사도와 폭에 대한 설계기준 역시 주로 이미 설치되어 있는 국내의 자연형 어도들을 근거로 제시되고 있는데, 이는 어종 특성은 물론 어도에 대한 수리학적, 생물학적 연구를 바탕으로 각 지역 조건에 맞는 설계기준이 새롭게 마련되어야 할 것으로 판단된다.

  • The strength of material is scattered owing to the inhomogenity of microstructure, in spite of the same material. Therefore, in order to design the mechanical structure with the reliability engineering, it is important to grasp the statistic nature of material strength. In this paper, effects of grain sizes for the statistical nature of the fatigue crack growth was discussed. And the statistical of mechanical properties was compared with statistical nature of the fatigue crack growth rate.

  • Studying the environments in which core-collapse supernovae (SNe) explode and evolve is essential to establish the nature of the mass loss and the explosion of the progenitor star. The spatial structure of the outer shock in young core-collapse SNR provides an excellent opportunity to study the nature of the medium into which the remnant has been expanding. I will review studies of the outer shocks in young Galactic SNRs using Chandra X-ray observations and discuss the nature of the winds and the progenitor stars.

  • This study aimed to develop strategies to re-establish the Park Nature Conservation Area in Bukhansan National Park, reflecting landscape ecological value by using the zonation program Marxan with Zones. Planning unit was set by watershed, and the basic data were mapped, considering topographical and ecological values. Mapped indicators were analyzed with the application framework of Marxan with Zones by indexing some indicators. The zones divided into Park Nature Conservation Area (Zone A), Park Nature Environment Area I(Zone B) which is reflected on the concept of Potential Park Nature Conservation Area and Park Nature Environment Area II(Zone C). The best solution for each of the scenarios was fixed through the sensitiveness analysis. From these, the final solution was selected considering five criteria including area ratio of conservation area and grouping. Lastly, the final solution was verified in the overlapped analysis with recent zonation. According to the results, the number of watersheds was 77, with an average area of $1,007,481m^2$. In terms of basic mapping and indexation, the slope index and number of landscape resources for topographical property were average 0.22 and 38 places, respectively. Biotope index was average 0.69 and legally protected species was 14 species, reflecting ecological values. As the social and economic indicators, trail index was average 0.04, and the number of tour and management facilities was 43 places. Through the framework of Marxan with Zones, the best solution for scenario 1 which was set by the highest conservation criteria was selected as the final solution, and the area ratio of Park Nature Conservation Area and grouping was excellent. As the result of overlapped analysis, suggested zonation of the Park Nature Conservation was better than the recent zonation in the area raito (28.3%), biotope grade I(15.4%) and the distribution points (10 places) of legally protected species with verification of proper distribution of conservation features according to the zone.

  • Contemporary society is lately going through various changes in social, economic, and cultural aspects due to rapid growth of information and computer technology. The digital revolution generated from the development of network reflects the decentralizing characteristic that connects local and personal interconnections. The following paper is designed to develop a basic understanding of digital architecture and show that digital virtual reality is not accidental phenomenon but it is actually evolved from nature and recreated in cyber space. The relationship between nature and digital architecture will be explained through the background research of how digital architecture was born and how it has been transformed. Also, it is designed to find out modern trends of digital architecture through diagrams and virtual space of hyper architecture and follow up the new phenomena appearing in the field of architecture. It is said that digital architecture is a new trend of architecture created from computer bit but all architecture that has form and shape cannot be independent of nature. Nature is the root of everything and even mechanical abstraction such as 'digital' can find its form in the immanence melted in the pure essence of nature. The research found that the nature approach of digital architecture also needs no more than 5 sequential references to find its genuine sketch as the hypertext theory shows we need only 5 sequential references to prove we are all related. Additionally, the cyber space that is become a general living space and a indispensable factor of digital architecture is a space that has obscurity and more open culture. It represents the characteristics of contemporaries in various aspects of society.

  • Contemporary Architecture is showing many aspects on the ground of ecological paradigm, while, searching for a new architectural direction to make importance of environment that has been still little accounted of a subject of discussion. And 'sustainability'will become a central concept of a Contemporary architectural topic, continuously. With a demand of the time, ecological inclinations have been started to develop a collective low-rise housing project. It is going to expands several fields, but for reasons of social economic activity for human fundamental being, potentialities of basic problem solution are enough for ecologyㆍenvironment, but distinct direction and measures are still not obvious conditions. This study is for healing restoration in global environment, with architectural approach, through analyzing relation between ecological architectural space and nature, and abstracts various inter-relational aspect's specific character. the purpose of this study is another approach of intimate relation of ecological architecture and nature. Therefore, this study is significant to be on the search for a start to suggest a new point of view to ecological architectural space.

  • Purpose: This paper is an attempt to explicate the principle of space and form-making in Le Corbusier's architecture from the viewpoint of integrating and relating architecture with the natural landscape. It shows thereby how the geometrical element of architecture and the non-geometrical element of the nature coexist in terms of form. It also explains how space is deployed for the construction of cognitive system between natural landscape and architectural scenery in terms of space, hoping to make a contribution to design method of contemporary house as an elementary datum. Method: Three issues are studied, focusing on the designs around nineteenth thirties in the earliest phase of Le Corbusier: How architectural form and nature is related, how natural greens is introduced into urbanism, and how natural landscape is introduced to house design. 1) it is studied how the relation between the nature and the formal elements of purism in Le Corbusier's architecture is formed. 2) it is studied how the relation between the nature and architecture proposed in Le Corbusier's urbanism is formed. 3) Le Corbusier's "four compositions" is analyzed in terms of relation-formation between architectural space and the nature. 4) it is studied how the natural landscape is introduced to Le Corbusier's house-design in the form of architectural promenade. Result: It has been found out that the natural landscape in Le Corbusier's architecture is not just a simple background, but a necessary element for the consummation of form and space in his architecture, and that architectural inspiration is maximized with coexistence with nature.

  • 1. Objectives: This research aims to study the general overview of the theories on the covetous desire and the relevant theories on cultivation mentioned in "Donguisusebowon (東醫壽世保元): Theories on Nature and Conduct (性命論)". 2. Methods: The theories concerning the covetous desire introduced in Dong-Mu's manuscripts, including "Gyukchigo 格致藁)", "Yougocho (遺稿抄)", "Dongmuyougo (東武遺稿)" and "Jaejungsinpyun (濟衆新編)", were comprehensively reviewed. Furthermore, the significance of the theories on the covetous desire and the relevant theories on self-cultivation were studied within the context of "Donguisusebowon(東醫壽世保元): Theories on Nature and Conduct (性命論)". 3. Results and Conclusions: 1) Among the four covetous desires (selfishness (私心), indiscretion (放心), indolence(逸心), acquisitiveness (慾心)), selfishness and acquisitiveness are the interpersonal components that deal with the relationship between individuals, whereas indiscretion and indolence are the intra-personal or self-concerned components that deal with the internal desires within the individual. 2) In the early concepts on the quaternity explaining the perspective on the human being as introduced in Dongmu's earlier manuscripts, the four covetous desires are thought of as the most important etiological components, that are also intimately related to the theories of self-cultivation. 3) Among the concepts introduced in "Donguisusebowon (東醫壽世保元): Theories on Nature and Conduct (性命論)", viciousness (邪心) and negligence (怠心) are primary, intra-personal (self-concerned) desires that are henceforth matched to indiscretion and indolence, respectively, while selfishness (arrogance, assertiveness, indiscrimination and exaggeration (驕矜伐夸)) and acquisitiveness (violation, extravagance, slothfulness and stealthiness(奪侈懶竊)) are secondary, interpersonal desires. 4) 'Preserving the mind (存其心)' and 'rectifying the body (修其身)' are Methods of overcoming viciousness (indiscretion) and negligence (indolence), the intrapersonal desires, while 'nurturing the nature (養其性)' and 'propping the course (立其命)' are Methods of eliminating selfishness and acquisitiveness, the interpersonal desires, which ultimately each leads to the completion of Nature (性) and Conduct/Course (命).
