This study was conducted to identify the influence of the discrimination experienced in daily life and social isolation on depression among older adults living in the community. This study was a secondary analysis of the data of 2017 Living Profiles of Older Adults Survey. The participants was a representative sample among the older adults 65 years and older. Data from 10,041 older adults were analyzed for this study. Hierarchical logistic regression analyses were used. When the discrimination experiences was added in model 1, the likelihood of being depressed was 1.95(1.60-2.36) times higher for those who experienced discrimination comparing with those who didn't experienced discrimination. When the social isolation was added in model 2, the likelihood of being depressed was 1.89(1.55-2.30) times higher in those who experienced discrimination. In addition, as the number of close friends, neighbors, and acquaintances decreased by one, the likelihood of being depressed increased by 1.14 times. Those who were isolated from family, friends, neighbors and acquaintances were 3.90 times more likely to be depressed. Therefore, social efforts are needed to reduce the experience of discrimination. Maintaining a social network or creating a new network will contribute to lowering the level of depression in older adults who have experienced discrimination.

In general, the stress is concentrated on the pillar of very near parallel tunnel (VNPT), and the pillar has been reinforced by using steel-wires to maintain the stability of the tunnel. However, since the strength of the pillar decreases in the soil layer, the reinforcing pillar with the steel-wires is insufficient for tunnel stability. In this study, the laboratory tunnel experiment was conducted to examine the reinforcement effect for a new method, of which the pillar of VNPT is strengthened by using steel-pipes. As a result, against overburden stress, the bearing capacity of the steel-pipe reinforcement was 22% greater than that of the steel-wire reinforcement. In using the Particle Image Velocimetry method, the analysis shows that the steel-pipe reinforcement forms a more favorable condition of which uniformly the overburden load acts on the VNPT and the pillar than the steel-wire reinforcement. Based on the results, the steel-pipe reinforcement is expected to bring a more positive effect on tunnel stability than the steel-wire reinforcement.

Start-up accelerators are a new type of investor that provide mentoring, education and seed capital to start-ups for a fixed duration and receive a certain stake in them in return. They help start-ups achieve successful commercialization. With increase in performance visibility, the number of private and public sector accelerators rose across domestic and international markets. Private sector accelerators are established and operated by private entities while public sector accelerators are established and operated by the government. Both play complementary roles that are becoming increasingly important to start-ups. Therefore, this study aims to examine the differences in major operational goals and investment determinants between private and public sectors and to understand their implications. The results show that the private sector prioritizes profit generation through the investment, while the public sector aims to contribute to the development of high-growth start-ups, and create region-specific and technology-specific start-up ecosystems. Additionally, both groups consider customer needs the most important determinant. Public groups are more conservative in investments and tend to place importance on objective indicators such as patents, partners, mentors, and co-founders. Conversely, private groups value the capabilities of founders and their ease of collaboration with accelerators. These findings can help start-ups get support from public or private accelerators more easily. It will also help public and private accelerators refine the criteria for selecting start-ups.

Chinese youth films fall into the dilemma of continuous development after experiencing rapid development from 2013 to 2017. How to update the creative ideas and methods of the films, arouse the audience's interest in watching and stimulate a new aesthetic experience has become a focal point for the creators who concern about the Chinese film market. "Us and Them" is a successful youth film in 2018. Its creative practice proves that defamiliarization can provide theoretical and methodological basis for the creation of Chinese youth films. Therefore, taking the current situation of Chinese youth film as the research background, treating "Us and Them" as the research object, the defamiliarization of narrative discourse and narrative content used in the film are analyzed. First, the defamiliarization of narrative discourse composed of scenes, characters and plots makes the film "stand out" from the real world. Second, the defamiliarization of narrative content composed of metropolis adoration, self-identity and hometown affection makes the film "stand out" from the existing context. These methods of creation not only meet the needs of the contemporary, but also provide an effective reference for the creation of other youth films. Research will be needed to utilize the elements of defamiliarization through the analysis of the successful case in spite of the time change.

Whenever a mineshaft accidentally collapses, speedy risk assessment is both required and crucial. But onsite safety diagnosis by humans is reportedly difficult considering the additional risk of collapse of the unstable mineshaft. Generally, drones equipped with high-speed lidar sensors can be used for such inspection. However, the drone technology is restrictively applicable at very shallow depth, failing in mineshafts with depths of hundreds of meters because of the limit of wireless communication and turbulence inside the mineshaft. In previous study, a three-dimensional (3D) scanning system with a single channel lidar was fabricated and operated using towed cable in a mineshaft to a depth of 200 m. The rotation and pendulum movement errors of the measuring unit were compensated for by applying the data of inertial measuring unit and comparing the similarity between the scan data of the adjacent depths (Kim et al., 2020). However, the errors grew with scan depth. In this paper, a multi-channel lidar sensor to obtain a continuous cross-sectional image of the mineshaft from a winch system pulled from bottom upward. In this new approach, within overlapped region viewed by the multi-channel lidar, rotation error was compensated for by comparing the similarity between the scan data at the same depth. The fabricated system was applied to scan 0-165 m depth of the mineshaft with 180 m depth. The reconstructed image was depicted in a 3D graph for interpretation.

It is not easy to predict the future society in the rapidly changing present, but it is said that a new social environment of sensibility and virtuality will come, and we should pay attention to the fact that women have entered this as the subject. This study is a literature review study on gender roles. Through the study, it was found that gender stereotypes that exist in our society allow men to enjoy a lot of vested rights just by being male, and that women have to endure pain because they are women is accepted as a matter of course. Living in the 21st century, we were able to know the reality that we could not escape the pre-modern patriarchal ideology and still worshiped the idea of preferring boys. Through this study, unlike other elderly groups, elderly people who live alone are likely to be cut off from society and lead a limited life in their own world. However, through the efforts of the government, local organizations, and individuals, the goal of welfare for the elderly is to increase the satisfaction of life for the elderly living alone so that they can enjoy a successful old age. From this point of view, the support measures for the elderly living alone will be effective only when systematic and complementary in various dimensions such as family structure, physical, economic, and social aspects.

In order to foster creative convergence talents in the era of the 4th industrial revolution, universities are changing from knowledge-oriented education to competency-oriented education, and the maker education program is attracting attention as a new educational method. Through maker program education, we tried to find out the level of convergence, creativity, caring, and communication competencies. A survey was conducted from May 2nd to May 13th, 2022 for 2nd and 3rd grade students in the Department of Radiology and Sports and Leisure who participated in the Maker Education Program at S University in Daegu City. Research results Convergence competency is 3.35 ± 0.78 points before maker program education, 4.37 ± 0.61 points after education, creative competency is 3.28 ± 0.78 points before maker program education, 4.07 ± 0.69 points after education, and caring competency is 3.71 ± 0.80 points before maker program education Points, 4.25 ± 0.64 points after training, and communication competency were 3.61 ± 0.70 points before maker program training and 4.16 ± 0.63 points after training. There was a statistically significant level difference in all four competencies compared with before training, and the level after training was improved (p<0.05). Through the operation of the maker education program, it was possible to see the effect of cultivating convergence, creativity, caring, and communication competencies. The maker education program can be seen as education for nurturing creative convergence talents in the era of the 4th industrial revolution, and I think that various maker education programs should be operated for more university students.

SRFC (Sub-Regional Fisheries Commission) requested to the ITLOS (International Tribunal for the Law of the Sea) an advisory opinion relating to the IUU (Illegl, Unreported, and Unregulated) fishing (Case No-21 of the ITLOS). Since, in the UNCLOS, there is no article authorizing the jurisdiction of the ITLOS full court's Advisory opinion, so various scholarly opinion wad divided. But ITLOS delivered its Advisory opinion confirming its jurisdictional competence over the Advisory proceedings with its legal opinion about the IUU issues. It opens new possibility of the alternative dispute settlement mechanism of the ITLOS through the advisory procedures. In reality, there has been a view that ICJ (International Court of Justice) could take the part of a kind of dispute settlement through its Advisory procedures. But the advisory procedures of the ITLOS, with no definite clause in UNCLOS about the advisory procedures, which provides more allowances for the function of advisory opinion as the alternative dispute settlement mechanism. ITLOS accepted the requests of the advisory opinion by the State parties through international organization or themselves directly. And the advisory opinion of the ITLOS aims the interpretation and application into the special issues-specially IUU fishing in Case No. 21 of the ITLOS-. Those factors could enable more enhanced role of the ITLOS as an alternative dispute settlement mechanism. But those possibility has contain risk of excessive and unlimited advisory role of the ITLOS. So it is important to focus on the restriction on the role of the State parties in the request of the advisory opinion to the ITLOS. In this regard it is meaningful that the ITLOS has suggested a kind of legal standing in the advisory procedures in that only coastal States could request the Advisory opinion about the IUU in their EEZ. Furthermore the discretionary power of the ITLOS in the Article 138 of the Rules of the Tribunal could curtail the abuse of the Advisory opinion initiated by the States parties of the UNCLOS. Under this framework, Advisory opinion could broaden more alternative option to the disputes between State parties of the UNCLOS in that after being delivered detailed interpretation of the UNCLOS about the specific issues, States parties could devote themselves to searching for flexible solution for the disputes between State parties. It could obtain legal explanation about the dispute under the Article 297 and Article 298 by detouring the jurisdiction limits through advisory procedures.

The pandemic of COVID-19 also affected performing arts business and stimulated 'Untact' performances, which means online streaming of the shows including real-time streaming. This study sought to examine factors to the consumers' acceptance. The research framework was based on the VAM, a revised model of TAM for the ICT products and services. For the research, consumer survey was conducted, where ndependent variables are perceived usefulness, pleasure, technicalty and innovation resistance, and dependent variables are percieved value and acceptance. Smart PLS was used to test the hypothesis. The result shows that the significant factors were percieved usefulness(+), pleasure(+) and innovation resistance(-). The percieved technicalty was not significant, the major reason would be that the digital devices and the internet technology are percieved a commodity these days in Korea. Percieved value was significant factor to acceptance. This study is meaningful because it is about the new phenomenon of 'untact' performance through the VAM methodology and it examined the significant factors to the attitude from the perspective of benefits and costs. There is limit that this study didn't consider old peoples' attitude. It is the reason that the continuous researches are necessary.
