Purpose: Sharing genetic information with family members is important for cancer awareness and prevention. The purpose of this study is to examine disclosure patterns of positive BRCA genetic test results to patients' relatives. Materials and Methods: A total of 106 probands who had positive BRCA genetic test results from the Korean Hereditary Breast Cancer Study participated in our study. Subjects were asked whether they had disclosed their genetic test results to first-, second-, and third-degree relatives. Univariate and multivariate analyses were used to identify factors associated with positive result sharing with close and distant relatives. Results: In total, 99 respondents (93.4%) informed at least one at-risk relative of the test result, and they all reported that they had disclosed their genetic test result to a first-degree relative. Communication of test results to other relatives occurred significantly less often, with only 31 of 99 subjects (31.3%) sharing their results with second- or third-degree relatives. In the results of univariate analyses, disclosure of genetic test results to more distant relatives was associated with marital status and months since post-test counseling. The reasons for communication were to provide information about the BRCArelated cancer risk and to recommend the genetic test. Conclusion: Most individuals with the BRCA mutation share their test results with first-degree family members; however, these results reach more distant relatives significantly less often. Therefore, it is necessary to encourage patients' communication with extended family members through systematic genetic counseling.

Implantable flexible sensor using polymer/metal multilayer processing technique for telemetrical real-time blood pressure monitoring is presented. The realized sensor is mechanically flexible, which can be less invasively implanted and attached on the outside of blood vessel to monitor the variation of blood pressure. Therefore, unlike conventional detecting methods which install sensor on the inside of vessel, the suggested monitoring method can monitor the relative blood pressure without injuring blood vessel. The major factor of sudden death of adults is a disease of artery like angina pectoris and myocardial infarction. A disease of circulatory system resulted from vessel occlusion by plaque can be preventable and treatable early through continuous blood pressure monitoring. The procedure of suggested new method for monitoring variation of blood pressure is as follows. First, integrated sensor is attached to the outer wall of blood vessel. Second, it detects mechanical contraction and expansion of blood vessel. And then, reader antenna recognizes it using telemetrical method as the relative variation of blood pressure. There are not any active devices in the sensor system; therefore, the transmission of energy and signal depends on the principle of mutual inductance between internal antenna of LC resonator and external antenna of reader. To confirm the feasibility of the sensing mechanism, in vitro experiment using silicone rubber tubing and blood is practiced. First of all, pressure is applied to the silicone tubing which is filled by blood. Then the shift of resonant frequency with the change of applied pressure is measured. The frequency of 2.4 MHz is varied while the applied pressure is changed from 0 to 213.3 kPa. Therefore, the sensitivity of implantable blood pressure is 11.25 kHz/kPa.

This paper analyses from the perspective of distributive justice the legal mechanisms for international allocation of orbital slots, which are of co-owned nature and thereby limited natural resources in outer space. The allocative function is delegated to the International Telecommunication Union. The Radio Regulation, amongst such other legal instruments as the Constitution and Convention, by which the ITU and contracting States thereof abides, dictates how the orbital positions are distributed. Thus, the RR is thoroughly reviewed in the essay. The mechanisms are in a broad sense categorized into two systems: 'a posteriori system' where the 'first come, first served' principle prevails; and 'a priori system' designed to foster the utilisation of the slots by those who lack space resources and are, in especial, likely to be marginalised under the former system. The argument proceeds on the premise that a posteriori system places the under-resourced States in unfavourable positions in the securement of the slots. In contrast with this notion, seven factors were instantiated for an assertion that the degradation of the distributive justice derived from the 'first come, first served' rule, which lays the foundation for the system, could be either mitigated or counterbalanced by the alleged exceptions to the rule. However, the author of this essay argues for counterevidences against the factors and thereby demonstrating that the principle still remains as an overwhelming doctrine, posing a threat to the pursuit of fair allocation. The elements he set forth are as in the following: 1) that the 'first come, first served' principle only applies to assignments capable of causing harmful interferences; 2) the interoperability of the principle with the 'rule of conformity' with the all the ITU instruments; 3) the viability of alternative registrations, as an exception of the application of the principle, on the condition of provisional and informational purposes; 4) another reference that matters in deciding the priority: the types of services in the TFA; 5) the Rule of Procedure H40 proclaiming a ban on taking advantage of coming first to the Register; 6) the technical factors and equity-oriented norms under international and municipal laws along with; 7) the changes of 'basic characteristics' of registered assignments. The second half of this essay illustrates by examining the relevant Annexes to the Regulation that the planned allocation, i.e., a priori system, bear the structured flaws that hinder the fulfillment of the original purpose of the system. The Broadcasting and Fixed Satellite Systems are the reviewed Plans in which the 'first come, first served' principle re-emerges in the end as a determining factor to grant the 'right to international recognition' to administrations including those who has not the allotted portions in the Plan.

In the era of the fourth industrial revolution, maker education is drawing attention as a method of student-led education. At a time when interest in maker education is also growing in technology education, figuring out what stage of concern(SoC) a middle school technology teacher is critical to effective implementation. This study analyzed SoC in maker education by layer sampling among 400 middle school technology teachers using Concerns-based adoption model. SoC was then obtained by measuring the origin using the SoCQ and then presenting it as a SOCQ profile. Gender, training experience with two lower variables were analyzed using t verification, working cities, teaching experience with more than three lower variables were analyzed using one-way ANOVA. Studies showed that SoC in maker education of middle school technology teachers showed the most similar characteristics to that of non-users. The difference in concern depending on gender was that male teachers were more concerned in maker education than female teachers. The difference in concern depending on the working city was that teachers working in the township were more concerned in the maker education than teachers working in the large city, and the difference in concern depending on the teaching career was higher among teachers with middle experience than those with low and high experience. There was also a higher stage of concern in maker education than in teachers without training experience. Therefore, it is necessary to provide middle school technology teachers with an introduction to the maker education and various information, teaching, learning and evaluation data to enhance overall concern and to support the use and evaluation of the maker education in the classroom by providing various teacher training and consulting on the maker education in the future. Further, through further study, we should conduct study that analyzes both Stage of Concern, Level of Use and Innovation Configuration, to put in the effort for effective settlement of maker education.

The purpose of this study was to propose management strategies through aesthetic landscape assessments for landscape units in the Han River riparian(HRR) area. First, this research reclassified the HRR into "natural," "artificial," "agricultural," and mixed landscape types and selected 37 representative case areas(about $1km{\times}1km$). This study found 71 landscape units in consideration of topography and land surface classification. Landscape assessment consisted of landscape quality and landscape integration assessment. The criteria for assessing landscape quality were "naturalness," "interest," "uniqueness," and "landscape function." "Landscape quality" was ranked into five grades using a matrix. The landscape integration assessment consisted of an inner integration assessment in each landscape unit and outer integration assessment among landscape units. As a result of the field study, case sites were found to have 4,288 landscape units and an area of $42.8km^2$. The forest area was found to have the most space with $11,580,905m^2$(27.1%), while the wet lands had just $52,348m^2$(0.1%). In the landscape quality assessment, about 30.5% of the total area consisted of landscape units that scored highest in "naturalness". In the landscape integration assessment, about 39.3% of the total area consisted of landscape units which scored highest in "integration", denoting visual interrelation and harmony. The existence of disparities in landscape quality in accordance with the form of the landscaping was determined using a Oneway ANOVA, with "naturalistic" landscaping scoring the highest and "artificial" landscaping scoring lowest. This study may contribute to making the HRR area a more ecologically sound and visually attractive landscape space. It is recommended that the aesthetical and ecological value of the landscape unit should be assessed simultaneously in the future.

Recently parks and green spaces contribute not only as a place of leisure but also for environmental welfare, social education, new jobs and $CO_2$ Emissions Reduction. Parks and green spaces are understood as urban infrastructures like roads and rivers. They are also included in social infrastructures like education, culture, and welfare facilities. These changes are applied to policies for parks and green spaces, many governments and local authorities make investments on them. The modification of policies for parks and green spaces in England is a good example about this trend From this view point, this study now deals with the changing process of policies, results, and evaluation. Some implications have been deducted. The first is the inducement in participation in policies and implementation of practices through policy papers. They are more practical than written laws which are composed of abstract sentences and generalizations. Secondly, the status of parks and green spaces is highly raised with the establishment of CABE Space and so on. This organization controls many different policies and programs related to parks and green spaces. Third is the funding for the improvement of parks and green spaces. Fourth, are the short-term measures, such as funding and management, and the long-term measures such as pursuing building of partnership and training. Fifth, the government strives to establish its partnership with the local authorities and communities through a spectrum of support in terms of information, monitoring, and developing good practices among networks. Finally, parks and green spaces are being addressed from multiple directions through the participation of numerous agents like voluntary groups, development companies, communities and so on. Recently, in Korea, the influences of the Sunset Law for Park Site, Landscape Architecture Law, Urban Forest Law, and other related ordinances have encouraged the review on the policies on parks and green spaces needed. However, there are not many studies about them. Owing to these reasons, the cases of England will he helpful.

Gardeners have a desire to not only enjoy a garden but to create the garden themselves and play the role of garden designer. However, they express a great difficulty in gardening activities such as planting and managing plants, the main materials of the garden, due to lack of expertise. Therefore, in order to encourage hobby gardening activities, it is necessary to understand the preferences of the gardeners so that they can easily experience and create a garden, and to provide information on gardening know-how and preferred plants according to places given high preference. This study analyzed the preference for places and plants characteristics according to the purpose of creating a garden. To this end, a questionnaire survey was conducted with visitors to the Korea Landscape and Garden Expo, expected to have been attended primarily by gardening enthusiasts. As a result, gardeners were divided into three groups: appraisal - purposed type, multifunctional type, and participation - purposed type. The group of appraisal purposed type preferred porches and terraces, and private home front yards as well as favored indoor places rather than outdoor places compared with other types. In selecting plants, they prefer plants that can be easily managed in an indoor environment and appreciate natural colors through the colors of flowers and leaves. The multifunctional type group preferred a private home front yard as a garden creation space. Compared with the other types, it showed a high preference for 'unoccupied land in urban housing' and 'community garden' and was analyzed as a group having a high understanding of garden activities. In selecting plants, this group preferred fruit trees or productive plants such as homegrown crops. The participation purposed type group preferred porches and terraces as well as private home front yards as a gardening space. For plants, they preferred plants that are easy to manage. It is meaningful that this study provided preferences for places and plant characteristics according to the creative purpose of the gardener and provided basic data for selecting the place and the plant characteristics of the garden according to the gardener's type.

The Urban Heat Island (UHI) Effect has intensified due to urbanization and heat management at the urban level is treated as an important issue. Green space improvement projects and environmental policies are being implemented as a way to alleviate Urban Heat Islands. Several studies have been conducted to analyze the correlation between urban green areas and heat with linear regression models. However, linear regression models have limitations explaining the correlation between heat and the multitude of variables as heat is a result of a combination of non-linear factors. This study evaluated the Heat Island alleviating effects in Seoul during the summer by using a deep neural network model methodology, which has strengths in areas where it is difficult to analyze data with existing statistical analysis methods due to variable factors and a large amount of data. Wide-area data was acquired using Landsat 8. Seoul was divided into a grid (30m × 30m) and the heat island reduction variables were enter in each grid space to create a data structure that is needed for the construction of a deep neural network using ArcGIS 10.7 and Python3.7 with Keras. This deep neural network was used to analyze the correlation between land surface temperature and the variables. We confirmed that the deep neural network model has high explanatory accuracy. It was found that the cooling effect by NDVI was the greatest, and cooling effects due to the park size and green space proximity were also shown. Previous studies showed that the cooling effects related to park size was 2℃-3℃, and the proximity effect was found to lower the temperature 0.3℃-2.3℃. There is a possibility of overestimation of the results of previous studies. The results of this study can provide objective information for the justification and more effective formation of new urban green areas to alleviate the Urban Heat Island phenomenon in the future.
