Breast cancer is the most prevalent oncological disease among women. Various psychosocial distress is common at the diagnosis, treatment, and posttreatment phase of breast cancer. For the treatment of breast cancer, not only medical treatment but also psychosomatic integrative care will be needed. Patients with breast cancer may lead to increased vulnerability to stress, adjustment disorder, anxiety disorder, and depressive disorder, and these psychiatric diseases and conditions are associated with recurrence or exacerbation of breast cancer. Psychosocial treatment of anxiety and depression could increase the quality of life of patients and decrease the recurrence and progression of breast cancer. In this article, we reviewed 5 clinical breast cancer survivorship guidelines focused on psychosomatic integrative care including psychosocial treatment and alternative treatment for psychosocial distress. Because 5 treatment guidelines were using various definitions of evidence, we confirmed evidence of various psychosocial treatments for patients with breast cancer based on the definition of evidence by the US Preventive Service Task Force (USPSTF) guideline. We also reviewed the effect size of psychosocial treatment for anxiety, depression, mood, and quality of life in patients with breast cancer. This article discusses the barrier to the delivery of psychosomatic integrative care and suggests integrative care planning for breast cancer. Multi-disciplinary teams, patient's needs assessment, information technology support, patient and caregiver engagement, planned periodic monitoring of psychosocial distress by a psychosomatic specialist or consultation-liaison psychiatrist are recommended as key features of a psychosomatic integrated care plan.

Urban land use changes by human activities affect spatial configuration of urban areas and their surrounding ecosystems. Although it is necessary to identify patterns of urban land use changes and to simulate future changes for sustainable urban management, simulation of land use changes is still challenging due to their uncertainty and complexity. Cellular automata model is widely used to simulate urban land use changes based on cell-based approaches. However, cell-based models can not reflect features of actual land use changes and tend to simulate fragmented patterns. To solve these problems, object-based cellular automata models are developed, which simulate land use changes by land patches. This study simulate future land use changes in Hanam city using an object-based cellular automata model. Figure of merit of the model is 24.1%, which assess accuracy of the simulation results. When a baseline scenario was applied, urban decreased by 16.4% while agriculture land increased by 9.0% and grass increased by 19.3% in a simulation result of 2038 years. In an urban development scenario, urban increased by 22.4% and agriculture land decreased by 26.1% while forest and grass did not have significant changes. In a natural conservation scenario, urban decreased by 29.5% and agriculture land decreased by 8.8% while each forest and grass increased by 6% and 42.8%. The model can be useful to simulate realistic urban land use change effectively, and then, applied as a decision support tool for spatial planning.

The paleogenetic analysis has become an increasingly important subject of archaeological, anthropological, biological as well as public interest. Recently, scientific research for human skeletal remains was more activated because of increasing awareness of the valuable archaeological information by the ancient DNA analysis. State of preservation of organic remains vary in different soil and burying environmental condition. Almost all available tissue disappear to analysis ancient DNA of bone in acidic soil caused by climate and geological features in Korea. Many preserved human remains excavated in the 'Heogwakmyo'(limelayered tomb of Chosun Dynasty Period) is able to explain through the relationship between burial conditions and bone survival form the burial method and ceremony. Ancient DNA analysis of excavated human bone form ancient tomb requires to remove contaminants such as microorganism's DNA and soil components that affect authentic results. Particularly, contamination control of contemporary human DNA is major serious problem and should verified by criteria of authenticity. In order to understand migration and culture of ancient population, when possible, ancient DNA studies needs to go abreast both radiocarbon and stable isotope studies because the dietary inferences will suggest ancient subsistence and settlement patterns. Also when the paleogenetic research supported with the arts and humanities research such as physical anthropology and archaeology, more valuable ancient genetic information is providing a unique results about evolutionary and population genetics studies to reconstruct the past.

In this study, we investigated the spatial variation in land use and topographic effects on water quality at the Geum river watershed in South Korea, using the ordinary least squares(OLS) and geographically weighted regression (GWR) models. Understanding the complex interactions between land use, slope, elevation, and water quality is essential for water pollution control and watershed management. We monitored four water quality indicators -total phosphorus, total nitrogen, biochemical oxygen demand, and dissolved oxygen levels - across three land use types (urban, agricultural, and forested) and two topographic features (elevation and mean slope). Results from GWR modeling revealed that land use and topography did not affect water quality consistently through space, but instead exhibited substantial spatial non-stationarity. The GWR model performed better than the OLS model as it produced a higher adjusted $R^2$ value. Spatial variation in interactions among variables could be visualized by mapping $R^2$ values from the GWR model at fine spatial resolution. Using the GWR model, we were able to identify local pollution sources, determine habitat status, and recommend appropriate land-use planning policies for watershed management.

A Collection Policy provides a direction to an archive, but also provides a foundation for developing practical measures of planning and collecting process. In terms of a Collection Policy, it enables detail collection as regulations or codes cannot be as defined as the level of collection, thus, it allows systematic and strategic approaches in collecting former presidents' records. In the case of United States, where the same presidential system exists as South Korea, although the individual Presidential Libraries and Museums have different periods of collections, the Collection Policy was implement a half century ago that is used as a foundation data for record collection. However, the Presidential Archives in South Korea do not have a Collection Policy implemented that the collection is based on 'collection regulations' and 'collection plans.' In the comparison of the Collection Policy at the Presidential Libraries and Museums in the United States and the "collection regulation" and "collection plan" at the Presidential Archives in South Korea, it shows that while the Presidential Libraries and Museums' Collection Policy applies the characteristics of individual presidents that the collection comprises the records from more than the appointed period that it includes various personal records of relating figures, events, regions, and even personal interest; the records are written in detail to the detailed scale and procedure. On the other hand, the Presidential Archives in South Korea, the records collected based on 'collection regulations' and 'collection plans' do not sufficiently apply the individual features of the former presidents that the collections remain as general and unclear. This is due to the absence of a Collection Policy that systemizes and sustains professionalism and consistency of collection plans and procedures. Hence, this study is conducted to propose collection policy implementation measures by analyzing the Collection Policy of the Presidential Libraries and Museums in the United States and identifying implications for applying individual president characteristics.

The interest in underwater acoustic sensor networks (UWASNs), along with the rapid development of underwater industries, has increased. To operate UWASNs efficiently, it is important to adopt well-designed medium access control (MAC) protocols that prevent collisions and allow the sharing of resources between nodes efficiently. On the other hand, underwater channels suffer from a narrow bandwidth, long propagation delay, and low data rate, so existing terrestrial node pairing schemes for non orthogonal multiple access (NOMA) cannot be applied directly to underwater environments. Therefore, a multi-dimensional node pairing scheme is proposed to consider the unique underwater channel in UWASNs. Conventional NOMA schemes have considered the channel quality only in node pairing. Unlike previous schemes, the proposed scheme considers the channel gain and many other features, such as node fairness, traffic load, and the age of data packets to find the best node-pair. In addition, the sender employs a list of candidates for node-pairs rather than path loss to reduce the computational complexity. The simulation results showed that the proposed scheme outperforms the conventional scheme by considering the fairness factor with 23.8% increases in throughput, 28% decreases in latency, and 5.7% improvements in fairness at best.

The purpose of this study is to explore the methods to activate and functional changes of rural centers to improve residents' quality of life and secure sustainability in rural areas. The existing policy for activating rural centers lacks for placeness because walking-focused features of a Myeon seat have been changed due to the improvement of physical environment for easy car accessibility. They also wanted to solve abandoned houses and secure parking lots in the landscape plan. Based on analysis results, design guidelines were suggested. Long-stay tourism programs for outside visitors should be developed through the rural center activation project. They should be linked with projects for preserving the history of Byeongyeong Fortress and developing Hamel Village. Mountain trails and waterfront should be created to enhance accessibility and linkage methods with other resources should be prepared. As Byeongyeong-myeon has various tourism resources, design guidelines for each element should be made for a macroscopic direction and systematic landscape management.

Special theaters were created to provide a sense of immersion and spectacles due to differentiated screens, sound, seating facilities, and advanced services, and also expanded screens. The purpose of this study is to perform comparative analysis of the technical characteristics formats shown in special theaters(3D film, 4DX, IMAX, ScreenX, and VR) in order to identify and find ways to overcome the technological limitations in production. The various formats show differences in field of view depending on the exhibition technology and these differences affect the mise-en-scene, narrative, and editing of the film and consequently result in changes in the production environment and process. Therefore, directors and creators must understand the technological features and limitations of the new formats before making their approach. However, a new format encounters limitations on production sets due to the decline of technical education and succession. In situations where shooting with a special camera is essential, the particular characteristics of each format should be carefully considered from the planning stage but financial problems arise due to increase in production period and cost. To overcome these various obstacles, it is essential to first identify problems and present alternatives through in-depth research on the production set of each format. Finally, this research aims to explore the prototype of each format and analyze the current state of production technology with formats that have not been adapted to the market trends by combining with the other formats and showing that they can survive in new ways.

Housing issues such as mushrooming slums remain as chronic in most developing countries. Due to the state's restrained capacity, the housing-vulnerable's self-help approaches have been increasingly inevitable and vital for addressing the housing issues. However, there are still two challenges: securing good quality with economic efficiency, and climate change mitigation and adaptation. This study aims at doing an architectural experiment by developing and educating the production of eco-friendly interlocking stabilized soil bricks (ISSB) by employing vernacular materials and technologies for housing-vulnerable communities in Indonesia. In collaboration with a local architectural NGO, the study features a co-creation workshop in which 40 evicted households participate in the whole process. Soil analysis, mixed design, compression tests, and economic analysis are carried out. This paper illustrates that ISSB also has a high potential as an alternative to a burned brick or a cement block. The application of ISSB to self-help housing is expected to have socioeconomic and environmental effects, thereby facilitating the housing-vulnerable's self-help approaches and contributing to addressing the housing challenges in Indonesia.

The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land ransportation systems. In a preliminary feasibility study stage and selection of optimal railway route, the energy efficiency and problems related to environment are usually considered. For the selection of optimal railway route, geographical features and facility of management are generally considered. Environment effect factors for the selection of environment-friendly railway router are focused and studied in this paper. In this study, various analysis of opinion of specialists (railway, environment, transport, urban planning, survey) and the guideline for construction of environment-friendly railway were accomplished. From these results of various analysis, 7 major categories (topography/geology, flora and fauna, Nature Property, air quality, water quality, noise/vibration, visual impact/cultural assets) were extracted. To select environment friendly railway route, many alternatives should be compared optimal route must be selected by a comprehensive assessment considering these 7 categories. To solve this problem, the selected method was AHP which simplifies the complex problems utilizing hierarchy, quantifying qualitative problems through 1:1 comparison, and extracting objective conclusions by maintaining consistency. As a result, a GUIbased program was developed which provides basic values of weighted parameters of each category defined by specialists, and a quantification of detailed assessment guidelines to ensures consistency.
