Hydrogen is expected to be widely applied in most sectors within the current energy system, such as transportation and logistics, and is expected to be economically and technologically utilized as a power source to achieve vehiclebon emission reduction. In particular, the construction of hydrogen charging station infrastructure will not only support the distribution of hydrogen electric vehicles, but also play an important role in building a hydrogen logistics system. Therefore, This paper suggest additional charging infrastructure areas in Seoul with a focus on supply according to the annual average growth rate (CAGR), centering on Seoul, where hydrogen vehicles are most widely distributed. As of February 2022, hydrogen charging infrastructures were installed in Gangseo-gu, Gangdong-gu, Mapo-gu, Jung-gu, and Seocho-gu in downtown Seoul. Next, looking at the number of hydrogen vehicles by administrative dong in Seoul from 2018 to 2022, Seocho-gu has the most with 246 as of 2022, and Dongjak-gu has the highest average growth rate of 215.4% with a CAGR of 215.4%. Therefore, as a result of CAGR analysis, Dongjak-gu is expected to supply the most hydrogen vehicles in the future, and Seocho-gu currently has the most hydrogen vehicles, so it is likely that additional hydrogen charging infrastructure will be needed between Dongjak-gu and Seocho-gu.

Purpose: DNA damage and repair responses are induced by metabolic diseases and environmental stress. The balance of DNA repair response and the antioxidant system play a role in modulating the entire body's health. This study uses a high-fat and high-calorie (HFC) drink to examine the new roles of a plant-based multivitamin/mineral supplement with phytonutrients (PMP) for regulating the antioxidant system and cellular DNA repair signaling in the body resulting from metabolic stress. Methods: In a double-blind, randomized, parallel-arm, and placebo-controlled trial, healthy adults received a capsule containing either a PMP supplement (n = 12) or a placebo control (n = 12) for 8 weeks. Fasting blood samples were collected at 0, 1, and 3 hours after consuming a HFC drink (900 kcal). The blood samples were analyzed for the following oxidative stress makers: areas under the curve reactive oxygen species (ROS) levels, plasma malondialdehyde (MDA), erythrocytes MDA, urinary MDA, oxidized low-density lipoprotein, and the glutathione:oxidized glutathione ratio at the time points. We further examined the related protein levels of DNA repair signaling (pCHK1 (Serine 345), p-P53 (Serine 15), and 𝛄H2AX expression) in the plasma of subjects to evaluate the time-dependent effects of a HFC drink. Results: In a previous study, we showed that PMP supplementation for eight weeks reduces the ROS and endogenous DNA damage in human blood plasma. Results of the current study further show that PMP supplementation is significantly correlated with antioxidant defense. Compared to the placebo samples, the blood plasma obtained after PMP supplementation showed enhanced DNA damage response genes such as pCHK1(Serine 345) (a transducer of DNA response) and 𝛄H2AX (a hallmark of DNA damage) during the 8 weeks trial on metabolic challenges. Conclusion: Our results indicate that PMP supplementation for 8 weeks enhances the antioxidant system against oxidative stress and prevents DNA damage signaling in humans.

It is not an exaggeration to say that our society is already one of disputes. Since circa 2010, the average number of lawsuits filed every year is upwards of six million cases, and resolving disputes through trials is already fully saturated. The functional roles of the court reflect that there are many lacking areas such as systems, tools, and procedures related to social integration. In addition, ADR, which is carried out in advanced capitalist nations to supplement the judicial functions, has also been implemented in our society for the past 60 years. However, for the reason why the usage rate of ADR did not increase for legal consumers, we cannot overlook government activities that did not make sufficient promotions related to the lack of awareness. In Korea, ADR is mainly composed of government-initiated types, and in particular, there is no ADR framework act that can play an integrated role. Furthermore, for the conciliation system of the court, over 80%of conciliation are conducted focusing on court of lawsuits, and legal basis and procedures between institutes are different for administrative ADR, and communication does not go smoothly, thus making it inefficient. Such examples cannot avoid being a background for criticism when considering the fundamental ideologies and beliefs of ADR. The Vinaya Pitaka of sangha related to ADR is a separate method for operating communities. This is the BDR (Buddhist Dispute Resolution) method that encompasses personal ethics, organizational ethics, harmony through various community gatherings, and adhikaranasamatha on the four issues that could occur in legal review procedures. This has become the sufficient background for succession and development for parisa sangha and gana sangha among individuals.

The purpose of this study was to develop the psychology-based naturalistic competency curriculum so that forest-related experts could fully play the role of a mediator between nature(forest) and human(visitors). The curriculum was designed in three parts: a pleasant life, a wise life, and a meaningful life. Contents were focused on recognizing and naming one's senses and emotions in nature, discovering nature-related memories and Naturalistic Intelligence, experiencing the flow in nature and activating the Default Mode Network. The curriculum supplemented by expert's advice was implemented as job training for forest-related experts, and the curriculum was finally revised by examining the understanding and utilization of the participants. As a result, the curriculum in three areas of emotion, cognition, and practice was completed. It is expected that this curriculum will be upgraded through evaluation in the future so that forest-related experts can provide more qualitative service by strengthening their naturalistic competency.

Objectives: The aim of this qualitative study was to investigate how members of the general public in Korea interpret the concept of health, and which dimensions of health are most important to them. We also explored their perceptions of the EuroQoL 5-Dimension (EQ-5D), including the EuroQoL visual analogue scale (EQ-VAS). Methods: We conducted face-to-face, in-depth interviews with 20 individuals from the general population, using a semi-structured interview guide. Content analysis was performed with verbatim transcripts and field notes to identify codes and categorize them according to their similarities and associations. Results: In total, 734 different codes were derived and classified into 4 categories. Participants cited the importance of both the mental and physical aspects of health, although they emphasized that the physical aspects appeared to play a larger role in their conceptualization of health. Participants noted that the EQ-5D has the advantage of being composed of 5 dimensions that are simple and contain both physical and mental areas necessary to describe health. However, some of them mentioned the need to add more dimensions of mental health and social health. Participants showed great satisfaction with the visually well-presented EQ-VAS. However, participants opined that the EQ-VAS scores might not be comparable across respondents because of different ways of responding to the scale. Conclusions: While physical health is a fundamental aspect of health, mental and social aspects are also important to Koreans. The content of the EQ-5D broadly matched the attributes of health considered important by Koreans.

The purpose of this study is to examine the extent to which smart contracts can be applied to the software export business and to find out the legislative issues to activate smart contracts. A smart contract is a computer program that automatically executes a contract when conditions are fulfilled. Smart contracts can play a pivotal role in the field that requires immediate execution of contract or in a highly standardized field with multiple parties involved. In the software export business, it is desirable to apply the smart contract partially rather than applying the smart contract to the entire process because various parties are involved and the process is very complicated. The business model of exporting packaged software, a completed software that is mainly licensed for use, rather than the business model of exporting customized software is suitable for using smart contracts because the project for implementing customized software is mainly focused in the development stage. When smart contracts are used in processes such as contract signing, payment, and project management, work efficiency can be increased. In addition, smart contracts can be used when conditions can be quantified, such as error penalties, in areas that previously required contracts with third parties such as banks, guarantors. In order for smart contracts to be actively used in practice, legal reviews on various issues are necessary including the legality of a smart contract and the validity as an electronic document of NFT (non-fungible token) certificate. Also, for the system stability preventing hacking, etc, the periodic verification or inspection by a third party is essential. To activate smart contracts in international transactions the international treaty regarding smart contracts is also necessary.

The public safety management guidelines were introduced in 2019 and continue to be dedicated to advancing comprehensive measures for public safety management, with a primary focus on prioritizing the safety and well-being of the public within governmental institutions. To achieve this goal, our previous study developed a establishment procedure of risk assessment-based safety inspection system for public institutions that order construction projects and applied it to highway construction projects to evaluate its effectiveness. To enhance the practicality of the establishment procedure, it is essential to collect and analyze feedback from stakeholders regarding its performance and suitability. This study conducted a survey involving 200 participants who had experience with the establishment procedure, and performed statistical analyses to evaluate its performance and applicability. The survey results indicated that the participants reported a high level of satisfaction (scoring 4 and above on a 5-point Likert scale) in several areas: specialization of safety inspection items for different types of work (with a satisfaction rate of 65%), the evaluation process for safety ratings (64.5%), and their willingness to recommend the procedure to other institutions (75.5%). In the factor analysis with Varimax rotation, two factors emerged: (1) a specialization factor related to safety inspection items, and (2) a grading factor associated with safety evaluation results. Regression analyses of these factors unveiled significant positive relationships with improvements in safety and health performance, including the prevention of fatal accidents, heightened safety responsibility, and raised safety inspection standards. The establishment procedure of safety inspection system developed in our previous study can play a crucial role in reducing accidents resulting in fatalities and injuries at construction sites, ultimately contributing to a safer working environment for all involved parties.

When situated in green landscapes, water bodies play a crucial role in positively influencing mood and mental health, yet research on the cognitive mechanisms underlying these therapeutic effects is lacking. This study is intended to examine differences in brain function among adult males exposed to forest landscapes with or without water bodies. The wooded landscapes included views of a waterfall, a valley, and a forest without water. The control group was exposed to a local urban landscape. Twelve adult males participated in a field experiment in which prefrontal cortex (PFC) activity was measured using near-infrared spectroscopy (NIRS). In the experiment, participants engaged in low-intensity walking in three forested areas with similar vegetation and climatic conditions. Participants showed significant differences in left PFC activity depending on whether they were in the three forested landscapes or in the control landscape (P < 0.01). An analysis of variance (ANOVA) confirmed that significantly lower left PFC activity was recorded in the wooded landscape containing a water view . Notably, the lowest PFC values recorded in the landscape with a waterfall view suggest that landscapes with dynamic water flow may be associated with greater therapeutic benefits in terms of PFC activity than static landscapes. Our results underscore that water is a critical aspect of a landscape due to its therapeutic benefits and should be incorporated in the planning and design of green spaces for health promotion.

Objective : This study was aimed to reassess the scope of practice for medical personnel based on laws. Method : The law specifying the scope of practice for medical personnel has been selected searching Korean Law Information Center(https://www.law.gov.kr). The result was categorized as 'examination, diagnosis, treatment, procedure, prescription, and others'. Results : The laws related to medical procedures were divided into three categories: diagnosis, treatments, and public health and others. In the field of diagnosis, traditional Korean medicine practitioners are generally allowed to play a role. However, some laws specify that only medical doctors can be the primary authorities for diagnosing infectious diseases. In the area of treatments, particularly in emergency medical situations, only medical doctors or nurses are typically mentioned. There are debates in the field of public health and other areas concerning issues such as vaccination, disability diagnosis, and the qualifications for health center directors. A reevaluation is also needed for the Occupational Safety and Health Act, where only medical doctors are set as the personnel standard for workers' health examinations. Conclusion : To safeguard and promote the health of the citizens, there is a need for a clear definition of the licensure and scope of practice for healthcare professionals. Consistent interpretation of conflicting provisions among various laws and clear criteria for the term 'physician' in legal contexts are essential.

Purpose: The planning of medical facilities involves formulating a comprehensive medical basic plan, translating it into spatial dimensions through a space program. Feasibility assessment often relies on empirical methods like floor area per bed. However, with the shift towards specialized medical concepts, proportional scaling to bed numbers is challenging. This study proposes scale planning improvements during the feasibility assessment stage for comprehensive hospitals, analyzing cases using area determination factors and standard areas based on medical resources. Methods: The Korean Development Institute's Public Investment Management Center (KDI) identified issues in the scale determination of medical facilities in the Preliminary Feasibility Study Guidelines and investigated alternative approaches for determining the scale of a case that passed the preliminary feasibility study in 2019. The study assessed the feasibility of applying individual factors to determine not only the number of beds but also the scale at the sector and department levels. Additionally, a statistical analysis was conducted to examine the correlation between the total number of beds and various area determination factors. Results: Results suggest a strong correlation between total beds and major equipment needs, but in hospitals with <500 beds, this correlation weakens. Ward section scale is better calculated per ward type, not just total beds. Outpatient department scale depends on specialists, influencing treatment room numbers. Medical personnel play a crucial role in determining the scale of sections like rehabilitation therapy rooms, operating rooms, dialysis rooms, and overall facility scale.
