In Korea, the concept of publicness, although conceptually unclear, is being used as a medium between religious groups and other areas of society. In this situation, it is necessary to discuss the concept and agenda of publicness related to religions. For this purpose, we reviewed the relationship and agenda between publicness and faith, and then analyzed the cases of creating sacred objects and holy sites in connection with the concept of publicness. Specifically, according to Chapter II, Publicness and Faith, theologians and sociologists interested in publicness generally presuppose or aim for social participation and change. In this context, the agenda related to religious publicness can include the ground of non-Christian publicness, interreligious equality in the public spheres, the status of religious bodies, and the participation of researchers in the public spheres. In Chapter III, Sacred Objects and Publicness, we divided religious publicness into 'publicness within religion' and 'publicness outside of religion.' According to this classification, rituals are a key factor in creating publicness within religion. Publicness outside of religion is not intrinsic, but is constructed through various external debates. In Chapter IV, Sacred Holy Sites and Publicness, we reviewed cases of the construction of Catholic holy sites and analyzed oppositional logic provided by other religious groups in relation to the publicness outside of religion. Those cases internally created publicness within religion but lead to evaluation and debate about publicness outside of religion in public spheres in which various religions participate. Those who opposed the creation of Catholic holy sites used the logic that Catholicism was eliminating the heritage and values of other religions, and responded by expanding this to include the logic that the Catholics were weakening publicness or creating religious bias.

Recently, with the development of autonomous vehicle technology, the importance of precise road maps is increasing. A precise road map is a digital map with lane information, regulations, safety information, and various road facilities. Conventional precise road maps have been tested and developed based on the mobile mapping system (MMS). But they have not been activated due to high introduction costs. However, in the case of unmanned aerial vehicles (UAVs), the application field is continuously increasing. This study tries to extract information through classification of high-resolution UAV images for autonomous driving. Autonomous vehicle test roads were selected as study sites, and high-resolution orthoimages were produced using UAVs. In addition, the utilization of high-resolution orthoimages has been proposed by effectively extracting data for precise road map construction, such as road lines, guards, and machines through image classification. If additional experimentation and verification are performed, the field of UAV image use will be expanded, providing the data to automobile manufacturers and related public and private organizations, and venture companies will contribute to the development of domestic autonomous vehicle technology.

This study focuses on the proposition that the qualities and environmental conditions required for exploring entrepreneurial opportunities and realizing entrepreneurial opportunities depend on the types of entrepreneurial opportunities. In particular, this study aims to identify the type of entrepreneurial opportunities for laboratory start-ups, which have recently been gaining policy level attention. If the type of entrepreneurial opportunities for laboratory start-ups is identified as discriminative, appropriate start-up support policies and training programs can be established. For this study, eight major papers were identified among the papers of last 30 years related to the types of entrepreneurial opportunities. After, the classification attributes for each opportunity type were derived. Then, the existing theories of recognition, discovery and creative opportunities were organized, critically reviewed and reorganized. In addition, the substance of laboratory start-ups was verified according to the standardized classification attributes of the revised and reorganized opportunity types and newly classified as 'creative opportunity'. This study also presents networking capabilities and market orientation as examples of the capabilities needed for entrepreneurs of creative opportunity type. The implication of this study is that it makes it easy to discriminate ontological typology of entrepreneurial opportunity, derives important classification attributes, and that it organizes them conceptually. In addition, it critically reconstructs the problems of confusion in the existing typology, and based on this, the type of entrepreneurial opportunities for laboratory start-ups is determined as creative opportunity. These achievements can contribute to the improvement of start-up policies and start-up training programs according to the types of entrepreneurial opportunity and laboratory start-ups in the future, resulting in realization of actual results at the start-up sites.

Several studies showed that the survival rate of stage IIIB disease with malignant pleural effusion is worse than stage IIIB disease without malignant effusion. But, malignant pleural effusion was considered T4. To analyze changes the survival time for malignant pleural effusion, in the seventh revision of TNM classification for lung cancer. The records of all patients had to have either a histological or cytological diagnosis of non-small cell lung cancer (NSCLC), who were admitted to Wonkwang university hospital between January 2004 and December 2006 were reviewed retrospectively. We evaluated the survival time of 187 patients with advanced lung cancer with and without malignant pleural effusion. This included the pleural effusion or nodule M1 a (pleural dissemination, currently classified as T4), nodule(s) in the other lung M1 a (contralateral lung nodule, currently classified as M1), nodule(s) with the same lobe as the primary tumor T3 (currently classified as T4), other T4 factors T4 (T4 MO anyN), and extrathoracic sites of disease M1b (distant metastasis, currently classified M1). Among the 187 patients, T4anyNMO was 57 patients in the current TNM classification. In the next edition of the TNM classification, T4MOanyN-T4 (excluding same lobe nodules) was 12 patients, pleural dissemiantion-M1a was 45 patients, contralateral lung nodule(s)-M1a was 7 patients, and metastatic disease-M1b was 55 patients. We compared the survival time for these groups. Survival time was 11 months, 8 months, 11 months, and 4 months. The survival time of malignant pleural effusion was shorter than other T4 factors without pleural effusion. But, there was no remarkable difference in statistics due to small cases (p=0.23). We strongly suggest that malignant pleural effusion in advanced NSCLC will be categorized with metastatic disease.

For classifying fire damaged areas and analyzing burn severity of two large-fire areas damaged over 100 ha in 2011, three methods were employed utilized supervised classification, unsupervised classification and Normalized Difference Vegetation Index (NDVI). In this paper, the post-fire imageries of SPOT were used to compute the Maximum Likelihood (MLC), Minimum Distance (MIN), ISODATA, K-means, NDVI and to evaluate large-scale patterns of burn severity from 1 m to 5 m spatial resolutions. The result of the accuracy verification on burn severity from satellite images showed that average overall accuracy was 88.38 % and the Kappa coefficient was 0.8147. To compare the accuracy between burn severity and field survey at Uljin and Youngduk, two large fire sites were selected as study areas, and forty-four sampling plots were assigned in each study area for field survey. The burn severities of the study areas were estimated by analyzing burn severity (BS) classes from SPOT images taken one month after the occurrence of the fire. The applicability of composite burn index (CBI) was validated with a correlation analysis between field survey data and burn severity classified by SPOT5, and by their confusion matrix. The result showed that correlation between field survey data and BS by SPOT5 were closely correlated in both Uljin (r = -0.544 and p<0.01) and Youngduk (r = -0.616 and p<0.01). Thus, this result supported that the proposed burn severity analysis is an adequate method to measure burn severity of large fire areas in Korea.

From PC communication to the development of the internet, a new term has been coined on the social media, and the social media culture has been formed due to the spread of smart phones, and the newly coined word is becoming a culture. With the advent of social networking sites and smart phones serving as a bridge, the number of data has increased in real time. The use of new words can have many advantages, including the use of short sentences to solve the problems of various letter-limited messengers and reduce data. However, new words do not have a dictionary meaning and there are limitations and degradation of algorithms such as data mining. Therefore, in this paper, the opinion of the document is confirmed by collecting data through web crawling and extracting new words contained within the text data and establishing an emotional classification. The progress of the experiment is divided into three categories. First, a word collected by collecting a new word on the social media is subjected to learned of affirmative and negative. Next, to derive and verify emotional values using standard documents, TF-IDF is used to score noun sensibilities to enter the emotional values of the data. As with the new words, the classified emotional values are applied to verify that the emotions are classified in standard language documents. Finally, a combination of the newly coined words and standard emotional values is used to perform a comparative analysis of the technology of the instrument.

The soils used as trackbed in Korea are selected using USCS utilizing basic soil properties such as Grain Size Distribution(GSD), % passing of #200 sieve ($P_{200}$), % passing of #4 sieve ($P_4$), Coefficient of uniformity ($C_u$), and Coefficient of curvature ($C_c$). Degree of compaction of the soils adapted in the code by KR should be evaluated by maximum dry density (${\gamma}_{d-max}$) and deformation modulus $E_{v2}$. The most important influencing factor that is critical to stability and deformation of the compacted soils used as trackbed is stiffness. Thus, it is necessary to construct a correlation between the modulus and the basic soil properties of trackbed soil in order to redefine a new soil classification system adaptable only to railway construction. To construct the relationship, basic soil test data is collected as a database, including GSD, maximum dry unit weight (${\gamma}_{d-max}$), OMC, $P_{200}$, $P_4$, $C_u$, $C_c$, etc.; deformation modulus $E_{v2}$ and $E_{vd}$ are obtained independently by performing a Repeated Plated Bearing Test (RPBT) and Light Weight Deflectometer Test (LWDT) for ten different railway construction sites. A linear regression analysis is performed using SPSS to obtain the relationship between the basic soil properties and the deformation modulus $E_{v2}$ and $E_v$. Based on the constructed relationship and the various obtained mechanical test data, a new soil classification system will be proposed later as a guideline for the design and construction of trackbed foundation in Korea.
