This is about studying on the environmental ethics of Taoism mainly based on Taoism's Bioautonomous. Taoism is the most comprehensive thought in the traditional thoughts of East Asia. According to Taoism, every individual bio has its own intrinsic value having nothing to do with the value estimated by human beings since it has Daoxing. Human beings, however, have their own bioautonomous which is different from other individual bio. In Taoism human beings are independent for their lives. They do not depend on nature, but they can control themselves. That is to say, their lives depend not on god but on their own wills. The human beings' bioautonomous includes two different meanings: one is that human beings can use other individual bio as a tool for their eternal youth, and the other is that human beings are the main character of realizing the intrinsic value of universal bio and bringing harmony into each individual bio. In Taoism the harmony of universal bio is considered as the top value. Realizing the value of human beings is based on keeping harmonious order of universal bio and realizing the value of other individual bio. the environmental ethics of Taoism is not Biocentrism. Biocentrism argues that each individual bio has teleological center of life, which pursues its own good in its own way, and possesses equal members of Earth's community. As a result, human beings role and responsibility was reduced. But Taoism insists on human beings' bioautonomous. And human beings should be responsible for universal bio's harmony. Therefore the environmental ethics of Taoism is not Biocentrism but Bioautonomous. Bioautonomous environmental ethics of Taoism insists on human beings should be responsible being in relation with other living beings. Because of this point, it can be a theory of biorecovery.

These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

Today, changes in the environments surrounding companies are so uncertain that corporate entrepreneurship should be activated to enhance the competitiveness of firms and to improve their profitability. In particular, The practice of entrepreneurship by small and medium sized enterprises (hereafter SMEs) is suggested as an important factor for the enhancement of competitiveness of firms. In this context, this study examined the effects of the organizational climates on the entrepreneurship activities of SMEs in Korea and China. The data obtained from 300 SMEs in Korea and China through questionnaire surveys were analyzed. The results demonstrate that the organizational climates have significant positive effects on SMEs in the countries belonging to emerging markets such as Korea and China. However, the practice of corporate entrepreneurship could be manifested in diverse forms, such as innovation or strategic renewal, and the effects of organizational climates were shown to sightly different effects on the corporate entrepreneurship activities. In addition, SMEs in Korea and China, which belong to common cultural areas, did not show any statistically significant difference in organizational climates in general. Furthermore, the effects of these factors did not show significant differences in general. However, SMEs in Korea with more flexible organizational structures and higher job autonomy were shown to be more advantageous in practicing corporate entrepreneurship than those in China. The results of the study provide meaningful implications for SMEs in Korea in terms of the efforts that should be made to enhance their competitiveness, implement innovation, and achieve comparative advantages over China.

After being kept in bonded areas and bonded logistics warehouses, the level of information sharing and progress confirmation on the process until the cargo is released is insufficient, resulting in disputes and legal disputes related to unauthorized and illegal delivery of cargo. This study attempted to present the introduction of standard electronic documents as a way to solve problems such as delivery practices raised in the delivery of existing imported cargo and legal disputes related to unauthorized illegal delivery among import-related entities. The service provider who manages the bonded warehouse/logistics center in the hinterland of Busan New Port and the shipper service user who use the service were classified into two groups, and a survey was conducted to analyze the difference in perception between the two groups. As a result of the analysis, both groups judged that the introduction of standard electronic documents was necessary, and showed high expected effects in preventing and reducing erroneous shipments and preventing and improving unauthorized and illegal shipments. Discussions between related organizations, related parties, and subjects are needed first to introduce standard electronic documents of the entry and warehouse management system, and the actual participation of related entities such as service providers and service users will play a very important role in establishing the system.

In some cases of head and neck cancers (HNC), surgical interventions may result in the loss of organs and/or changes to their functions, thereby significantly affecting the patient's quality of life. As a result, the surgical treatment of HNC patients is often limited to specific cases, and alternative treatment modalities, such as chemotherapy, are considered. However, serious adverse effects caused by chemotherapy, such as severe nausea and vomiting, necessitate the need for the development of adjunctive methods to minimize patient suffering. Chuanxiong, Ligusticum chuanxiong (L. chuanxiong), is a natural herb used in Eastern medicine to treat cerebrovascular disorders and headaches. This study aimed to predict the effect and potential of L. chuanxiong as an auxiliary anticancer drug through network-based pharmacology and molecular docking analysis. The study results showed that 40 out of 41 genes of L. chuanxiong shared common targets of HNC and their proteins could be used to target HNC cells to prevent cancer progression. The results of the functional enrichment analysis confirmed that L. chuanxiong is associated with the neuroactive-ligand metabolism and neurotransmitter pathways, indicating its potential medicinal value as an adjuvant in HNC treatment. Lastly, our findings demonstrated that the active ingredient of L. chuanxiong, (Z)-Ligustilide, has the ATP binding site of heat shock protein 90, a protein known to promote the activation of cancer cells. These results suggest that L. chuanxiong is a promising candidate for developing auxiliary anticancer drugs, and further research could potentially lead to the discovery of newer and safer anti-cancer agents.

Generative AI services, including ChatGPT, were becoming increasingly active. This study aimed to empirically analyze the factors that promoted and hindered the diffusion of such services from a consumer perspective. Accordingly, a research model was developed based on the Value-based Adoption Model (VAM) framework, addressing both benefit and sacrifice factors. Benefits identified included usefulness and enjoyment, while sacrifices were security and hallucination. The study analyzed how these factors affected the intention to use generative AI services. A survey was conducted among college students for empirical analysis, and 200 valid responses were analyzed. The analysis utilized structural equation modeling with AMOS 24. The empirical results showed that usefulness and enjoyment had a significant positive impact on perceived value, while security and hallucination had a significant negative impact. The order of influence on perceived value was usefulness, hallucination, security, and then enjoyment. Perceived value had a significant positive impact on usage intention. Moreover, perceived value was found to mediate the relationship between usefulness, enjoyment, security, hallucination, and the intention to use generative AI services. These findings expanded the research horizon academically by validating the effectiveness of generative AI services based on existing models and demonstrated the continued importance of usefulness in a practical context.

Nuclear power plants (NPPs) consider possible external events, including natural hazards, during the design phase to ensure safe operation. However, in recent years, due to the increasing probability of natural hazards exceeding the design, a careful review of extreme natural hazards and unforeseen external events during the design phase has become necessary. In this study, the objective was to screen potential extreme natural hazards at NPP sites in Korea. Initially, we investigated and analyzed the characteristics of NPP sites and the events caused by external hazards. Furthermore, we analyzed existing literature and research data to establish screening procedures and criteria that suit the actual conditions of domestic NPPs. Based on these criteria and data, we conducted qualitative screening for each NPP site and identified potential extreme natural hazards through quantitative screening and walkdown. As a result of the screening, in addition to internal flooding caused by heavy rain, wind pressure and extreme air pressure caused by extreme winds were screened as potential extreme natural hazards common to all sites. Additionally, at the Kori site, storm surge was selected as the most significant potential extreme natural hazard.

In this study, a total of 326 data on a variety of geometric parameters of pick cutters and the corresponding cuttable rock conditions were collected and built as a database. Statistical analysis of the database showed that there is a significant positive correlation between the parameters that define the geometry of a pick cutter, especially between the parameters related to the length of a pick cutter and the geometry of a tungsten carbide insert. The diameter of a pick cutter shaft was also strongly correlated with the geometry of the inserts. On the other hand, it was difficult to find a clear correlation between the parameters for the rock conditions defined by the four conditions and the geometric parameters of pick cutters, which may be due to the uncertainty of the rock mass and the fact that the application of a pick cutter is presented as a range rather than a numerical single value. However, the mean values of geometric parameters of pick cutters tend to increase as a rock mass becomes harder. However, the pick length parameters are found to decrease as a rock mass becomes harder, which may be a way to reduce the moments that can occur when using long pick cutters in a hard rock condition.

Recently, research on predicting ground classification using machine learning techniques, TBM excavation data, and ground data is increasing. In this study, a multi-classification prediction study for uniaxial compressive strength (UCS) was conducted by applying random forest model based on a decision tree among machine learning techniques widely used in various fields to machine data and ground data acquired at three slurry shield TBM sites. For the classification prediction, the training and test data were divided into 7:3, and a grid search including 5-fold cross-validation was used to select the optimal parameter. As a result of classification learning for UCS using a random forest, the accuracy of the multi-classification prediction model was found to be high at both 0.983 and 0.982 in the training set and the test set, respectively. However, due to the imbalance in data distribution between classes, the recall was evaluated low in class 4. It is judged that additional research is needed to increase the amount of measured data of UCS acquired in various sites.

In this study, the linear cutting tests of pick cutters were carried out on a granitic rock with the average compressive strength over 100 MPa. From the tests, the correlation between the cutter acting force and the temperature measured by infrared thermal imaging camera during rock cutting was analyzed. In every experimental condition, the maximum temperature was measured at the rock surface where the chipping occurred, and the temperature generated in the rock was closely correlated with the cutter acting force. On the other hand, the temperature of a pick cutter increased up to only 36℃ above the ambient temperature, and the correlation with the cutter force was not obvious. This can be attributed to the short cutting distance under laboratory conditions and the high thermal conductivity of the tungsten carbide inserts. However, the relatively high temperature of the tungsten carbide inserts was found to be maintained. Therefore, it is recommended that a reinforcement between the insert and the head of a pick cutter or the quality improvement of silvering brazing in the production of a cutter is necessary to maintain the high cutting performance of a pick cutter.
