The global elderly population, aged 65 and over, reached approximately 10% in 2020, and this proportion is expected to continue rising. Therefore, the prevalence of neurodegenerative diseases such as Parkinson's disease (PD), which are characterized by declining memory capabilities, is anticipated to increase. In a previous study, we successfully restored the diminished memory capabilities in a fruit fly model of PD by administering an omija extract. To identify functional ingredients that can enhance memory akin to the effects of the omija extract, we conducted screenings by administering halophyte extracts to the PD model. Halophytes are plants that thrive in high-salt environments, and given Korea's geographic proximity to the sea on three sides, it serves as an optimal hub for the utilization of these plants. Upon examining the effects of the oral administration of 12 halophyte extracts, Salicornia herbacea and Calystegia soldanella emerged as potential candidates for ameliorating memory loss in PD model flies. Moreover, our findings suggested that C. soldanella, but not S. herbacea, can mitigate oxidative stress in DJ-1β mutants.

After conducting a hydrogen bomb test and launching an intercontinental ballistic missile (ICBM) in 2017, The Democratic People's Republic of Korea (North Korea, D.P.R.K.) declared the completion of its national nuclear capabilities. Currently, North Korea is refusing all nuclear inspections, but the possibility of nuclear inspections and the denuclearization process on the Korean Peninsula still exists. The Republic of Korea (South Korea, Rep. of Korea) has numerous reasons as a neighboring country to participate in North Korea's nuclear inspections and denuclearization, including technological capabilities, geographical proximity, and linguistic benefits. This study assumes nuclear inspections and verification within North Korea and aims to propose scenarios for the transportation and operation of personnel and equipment. The data and results compiled through this research are anticipated to serve as foundational information for future inspections and verifications on the Korean Peninsula. Furthermore, it is assessed that they could contribute to the development of strategies in preparation for participation in denuclearization efforts.

A firm's competitive capabilities become greater when the firm has a specific knowledge. There are many studies have been examined how to accumulate the firm specific knowledge and to get the competitive capability on the various perspectives. This study suggest that the conceptual framework on the absorptive capability through reviews on the knowledge management theory. And it also suggests that the proposition about the technological capability building process through the in depth case study on a small and medium sized company in a LCD industry. This study found the following major characteristics about the absorptive capability building and knowledge creating process. First, it is required to building an absorptive capability rapidly that the harmony of local capabilities, integrative capabilities, and intensity of effort. And the most important factor is the intensity of effort in a small and medium sized firm with a weak knowledge base. Second, it is required to develop an innovative new product that the utilization of expeditious learning mechanism based on the exploration and exploitation process. Finally, complementary assets are needed to proactive exploration and exploitation. Based on the findings, the theoretical and managerial implications are derives and the further research directions are proposed.

In the event of a disaster (or accident), first of all, the ability to respond to an immediate disaster is important. This study investigated the disaster response capacity and the effects of disaster response exercise personnel. A questionnaire consisting of 28 items was used to assess disaster response capabilities. The questionnaire consists of contrast, preparedness initial response, warning, and response steps. Survey participants are self-service fire-fighters of small and medium-sized manufacturing companies participating in exercise. The effectiveness of the exercise. was measured by dividing the subjects before and after the exercise. Analyzing the difference between before and after exercise, it was confirmed that disaster response exercise. had significant effects on improving disaster response capacity. This study suggests that the disaster response exercise. has the effect on the disaster response capacity of the members and the necessity of disaster response exercise. As in the case study, if a company or organization regularly conducts disaster response exercise., its disaster response capabilities will improve. In addition, it is anticipated that in the event of a disaster (or accident), it will be possible to prevent or reduce property damage as well as property damage.

The numbers of occurrences and the amount of spills of marine oil pollution have increased, and accordingly, it is necessary to secure additional control capabilities. Therefore, it was intended to present an empirical basis for improving the overall idle capacity through the relocation of control ships existing in each region. First, the marine pollution index was derived and the control capability compared to the marine pollution index of each region was compared to examine the appropriateness of the deployment of control ships. The marine oil pollution risk index was derived by multiplying the nine items that cause marine pollution by the weight derived by experts. We checked the control capacity (A) compared to the marine pollution risk index (F) for each sea area. Mokpo (F:13.4, A:1.9), Busan (F:14.3, A:6.4), and Yeosu (F:21.5, A:16.6) are the areas that lack control capabilities compared to the marine pollution risk index. On the other hand, the areas that have room for control compared to the marine pollution risk index for each sea area are Masan (F: 5.9, A:13.3), Gunsan (F:1.7, A:8.3), and Jeju (F:2.7, A:6.9). Therefore, for improving the standardized control capacity proportional to the risk of marine pollution nationwide, it is suggested that the control ships of Masan, Gunsan, and Jeju should be relocated to Mokpo, Busan, and Yeosu, which lack control capacity.

This study analyzed the relationship between the level of the venture environment, the benefits of the venture business verification system, internal capabilities, and management performance through the actual data of domestic venture companies collected in the Venture Business Precision Survey. As a result of the empirical analysis, the level of venture infrastructure did not affect the company's capabilities, but it was found that the venture company confirmation system had a positive effect. In the case of corporate competency, it was found that it had a positive effect on technological performance, but had no effect on sales performance. However, the research results confirmed that internal competency mediates the relationship between the venture environment level and the benefits of the venture business confirmation system and business performance. This study has the implications of confirming a series of processes leading to competency and performance in the environment using data from actual venture companies, and confirming the importance of corporate competency. In addition, since we confirmed the effect of the environmental factors of the venture environment level and the venture business confirmation system on the internal performance, if the process is introduced in the later reorganized venture business confirmation system, we will examine the factors that can enhance the performance of venture businesses. A more precise check is expected.
