There often is information asymmetry between start-ups and the investors, which is because start-up companies in the early stages do not have track records. Meanwhile, since the government grants programs go through a fair and the intense competition process, the government grants can provide a more objective information for start-ups in the early stages and perform a signal function that guarantees a company's capabilities and potential. This study confirms the quantitative relationship between government grants and investment attraction by using the hurdler model. We found that, although there is the proportionate relationship between the scale of government grants and that of external funds, more than a certain amount of government grants is required for technology-based start-ups to exceed the stage of attracting their first external funds. Our findings suggest that it is necessary to consider the hurdles structure in the study of signaling theory perspective, as the mechanisms for determining whether or not to attract external funds are different from determining the level of external funds. In addition, differentiated policy support is needed to help early-stage technology start-ups go beyond the threshold of investment attraction-the creation of a 'threshold effect'.
This paper summarizes the concept of ludonarrative dissonance that occurred in the realm of full-scale game criticism, and materializes it with the latest work . In the process, it is examined that this game actively utilizes the ludonarrative dissonance to deliver cognitive experiences to players that go beyond the definition of gameness. Along with the all-round development of AAA-class games, the ludonarrative dissonance is emerging as an important task that each game must overcome. On the contrary, however, it should be noted that has a different effect than expected by revealing rather than overcoming the ludonarrative dissonance. The ludonarrative dissonance conveyed by has the effects of ironic interpretative possibilities. This paper looks at dissonance in two dimensions, and the first is the dissonance between the play-narrative structure inside the game. induces the player to recognize the dissonance and actively reconstruct the meaning of the whole game by reminding the player of the dissonance that occurs between the two structures. Second, it stimulates the cognitive dissonance that exists inside the player playing the game beyond the internal structure of the game. That is, by expanding the concept of gameness, it evokes the possibility that games can function more than a tool for convenient self-efficacy. As such, the ludonnarrative dissonance can be a more fundamental redefinition of game nature and an expression of a problem consciousness about the possibility of change.
In Korea, the cities continue to deteriorate, while the vacant houses in the small local towns emerge as a serious social problem. Despite the vacant houses emerge as a serious social problem in the small local towns as well as in the large cities, the basic researches into them are yet to be conducted on a full scale. Thus, in order to know about the spatial distribution of the vacant houses, this study conducted the square analysis and the kernel density analysis. As a result, it was confirmed that the vacant houses in Okcheon-gun had certain crowding forms and characteristics at the level of statistical significance. Next, in order to examine the distribution of the vacant houses in terms of the accessibility to the living SOC facilities, the GIS network analysis was performed, focusing on the major facilities and road networks. As a result, it was found that the better the accessibility to the living SOC facilities such as medical and well-being was, the ratio of the vacant houses was lower. In contrast, it was found that the accessibility to the obligatory facilities such as public administration and educational facilities did not have any important effects on the distribution of the vacant houses. All in all, through this study, the spatial distribution of the vacant houses in the small local town and their accessibility to the major SOC facilities could be analyzed.
The purpose of this study was to investigate the current status of practical course operation in a non-face-to-face online environment, learning effects, and students' experiences and perceptions for radiology major students using a survey. The questionnaire consisted of a total of 34 items in 5 areas: general characteristics of subjects, current learning participation in non-face-to-face environments, learning satisfaction, learning outcomes, improvement and requirements. For the analysis of the questionnaire responses, frequency analysis was performed on the response frequency, ratio, and scale for each item. Based on the general characteristics of the survey respondents, cross-analysis was performed using the chi-square test for participation in non-face-to-face learning, learning performance, and learning satisfaction. implemented. Improvements and requirements were qualitatively analyzed for the repetition frequency of words with the same meaning. Through the results of analyzing the responses of a total of 397 questionnaires, the direction of design and development of practical classes in a non-face-to-face environment in the future and basic information and implications for efficient operation were confirmed. Based on this, it is necessary to continue to think and make efforts for the efficient operation of non-face-to-face practice classes in the post-corona era.

Public consent is essential to proceed with large-scale projects such as dam and hydroelectric power plant in the Carbon Neutral Era. In general, when designing facilities such as dams and river facilities, the impact due to constructing them is analyzed through numerical simulation in advance. Those facilities are built to cope with floods and usually HEC-RAS is used for numerical simulation in this process. The numerical simulation provides accurate data, but it is very difficult to persuade the public only with the data. Therefore, this study intends to consider the utilization of metaverse in the field of urban flooding and flood response. The applicability of metaverse was confirmed by emphasizing visual effects and providing easy-to-see data, using a kind of metaverse platform called Cities: Skylines. The functions and limitations of this platform were reviewed. A virtual flood scenario was applied after implementing real cities on a metaverse. The hazard map established in Korea and the results of applying the scenario of metaverse platform were compared. On the metaverse, not only the disaster situation caused by realizing the city and society as it is, but also the spread of social disasters after the disaster can be confirmed. Through this, countermeasures can be virtually implemented. If these social and humanistic data are also verified in the future, it is expected that the overall process for responding to urban flooding can be modeled.
Purpose: This study proposes a concert oriented music therapy (COMT) program which takes into account the personal and social factors of depression, and its clinical effects were validated on elderly persons with visual impairments who were susceptible to depression. The experiment was conducted on 34 elderly persons with visual impairments, randomly allocated to either the experimental group (n = 15) or the control group (n = 19). The COMT program was applied 20 times in total to the experimental group for 110 minutes every other week, for a duration of 10 months. The depression level was evaluated using the Korean form of the Geriatric Depression Scale (KGDS). The experimental results showed that the average KGDS score in the experimental group decreased by 4.1 points (19.4%), from 21.0 to 16.9, whereas it increased by 1.16 points (5.8%), from 19.95 to 21.11, in the control group. The reduction in the depression level was significant for the following 4 depression factors : decreased social interest (40%), negative thinking and the unhappiness feeling (20%), emotional discomfort (16.3%), and cognitive dysfunction (7.6%), whereas it was negligible in the factors of physical weakening and decreased vitality. The COMT program reduced the KGDS scores of the experimental group regardless of their experience in musical performance. In conclusion, the proposed COMT program proved to be efficacious in alleviating depression in elderly persons with visual impairments. In particular, it proved highly effective in helping with decreased social interest, namely, the social factor of depression which is not properly considered in existing music therapy methods.

As the development of renewable energy expands internationally to cope with global warming and climate change, the share of wind power generation has been gradually increasing. Although wind farms can produce electric power for 24 h a day compared to solar power plants, Their interfere with the operation of nearby radars or communication equipment must be analyzed because large-scale wind power turbines are installed. This study analyzed whether a land radio station can receive sufficient signals when a ship sailing outside the offshore wind farm transmits distress signals on the VHF band. Based on the geographic information system digital map around the target area, wind turbine CAD model, and wind farm layout, the area of interest and wind farm were modeled to enable numerical analysis. Among the high frequency analysis techniques suitable for radio wave analysis in a wide area, a dedicated program applying physical optics (PO) and shooting and bouncing ray (SBR) techniques were used. Consequently, the land radio station could receive the electromagnetic field above the threshold of the VHF receiver when a ship outside the offshore wind farm transmitted a distress communication signal. When the line of sight between the ships and the land station are completely blocked, the strength of the received field decreases, but it is still above the threshold. Hence, although a wind farm is a huge complex, a land station can receive the electromagnetic field from the ship's VHF transmitter because the wave length of the VHF band is sufficiently long to have effects such as diffraction or reflection.

This study aimed to evaluate the effectiveness of Korean rehabilitation treatement for patients with post-TKR. The medical records of inpatients undergoing Korean rehabilitation treatment after TKR from 2016.01.01. to 2021.12.31. during the admission, were analyzed retrospectively. The effect of treatment was evaluated by using a numeric rating scale(NRS) and range of motion(ROM) of knee. Statistical analysis was done using the IBM SPSS statistics 26 program. If the period of hospitalization was within 7 days or change of NRS and ROM was not recorded properly, the case was excluded. All inpatients received acupuncture treatment, Electro-acupuncture. Soyeom pharmaco-acupuncture were used at a high rate. Blood letting cupping therapy, dry cupping therapy, Interferential Current Therapy(ICT) continuous passive motion(CPM), cryotherapy were used at a high rate. A significant improvement was noted when comparing the NRS and knee ROM results at the time of admission and discharge. Korean medical rehabilitation can be effectively used for patients who have undergone TKR, to relieve pain and enable returning to daily activities. It is expected to be helpful in future studies of post-TKR in Korean Medicine. Also It can be used for medical treatment of post-TKR in Korean Medicine Hospital and clinic. However, further research with a high level of evidence is necessary to support this finding.
Objectives: This study examined the effectiveness of Korean medical treatment for two patients complaining of discomfort after receiving Pfizer COVID-19 vaccine. Methods: The patients were hospitalized for 50 days and 12 days, respectively. They were treated with herbal medicine, acupuncture, electroacupuncture, and moxibustion. We used the Numerical Rating Scale (NRS) on numbness in extremities and headache, Manual Muscle Testing Grading System (MMT), Criteria for Sweating Categorization, and 36-Item Short Form Health Survey (SF-36) to evaluate the clinical effects of the treatment. Results: In Case 1, headache improved from peak NRS 9 and average NRS 7 on admission day to both NRS 3 on discharge. The SF-36 score was also increased, suggesting that the quality of life was improved. In Case 2, numbness in the extremities improved from NRS 8 on the day before admission to NRS 2 on discharge, and general condition also improved. Conclusions: This study suggests that Korean medicine can be an effective treatment for patients who experience long-lasting discomfort after being vaccinated with COVID-19, but with no abnormal findings in the examination.
Purpose: The purpose of this study was to investigate the effect of McConnell taping and Kinesio taping on pain and lower extremity joint angles when patients with patellofemoral pain syndrome (PFPS) ascend stairs. Methods: Fifty young adults who were experiencing anterior knee pain due to PFPS were selected as participants. Then, 25 patients were randomly assigned to the McConnell taping group and 25 to the Kinesio taping group. Pain and lower extremity joint angle were measured while ascending stairs before and after the intervention. A paired t-test was performed to evaluate the amount of change in the parameter values after the intervention within the groups, and an independent t-test was used to compare the results of the groups. Results: In the within-group comparisons, a statistically significant difference was found in both groups between the anterior knee pain scale scores recorded before and after the intervention (p < 0.05). A statistically significant difference was also found between the groups (p < 0.05). Comparison of the lower extremity joint angles at initial contact, loading response, terminal stance, and pre-swing within the groups showed that there were statistically significant differences in the hip, knee flexion, abduction, lateral rotation, and dorsiflexion angles in both the McConnell and Kinesio taping groups (p < 0.05). There was also a statistically significant difference in all angles between the groups during the following events (p < 0.05): (1) at initial contact, (2) at loading response (except hip flexion angle), (3) at terminal stance (except hip flexion and lateral rotation angles), and (4) at pre-swing (except hip, knee abduction, and inversion angles). Conclusion: McConnell taping and Kinesio taping both effectively improved the occurrence of knee pain and the lower extremity joint angles during stair ascent in patients with PFPS. However, McConnell taping had a significant impact on pain reduction and lower extremity joint angles compared to Kinesio taping.
