Purpose: This study was performed to identify levels of clinical practice stress and coping strategies according to the personality/behavior types of nursing students. Methods: The subjects of this study were 143 third- and fourth-grade nursing students in 14 nursing colleges who had experienced clinical practice. The questionnaire consisted of instruments to identify Dominance, Influence, Steadiness, and Conscientiousness (DISC) personality/behavior types, clinical stress, and stress coping strategies. The data were analyzed using Cronbach's ${\alpha}$, descriptive statistics, and ANOVA, using the SPSS 24.0 program. Results: The DISC pattern showed high priority in Steadiness (48.3%), followed by Conscientiousness (21.0%), Influence (16.1%), and Dominance (14.7%), in that order. The steadiness type showed the lowest level of stress among four patterns. Conclusion: This study found that the personality/behavior types of nursing students differ. Additionally, different personality/behavior types can be attributed to stress levels and stress coping behaviors. Based on these results, different personality and behavior types of nursing students should be considered to manage their stress levels related to the clinical practicum experience.

Background: The Korea Risk Information Surveillance System (K-RISS) was developed to enable the early detection of food and drug safety-related issues. Its goal is to deliver real-time risk indicators generated from ongoing food and drug risk monitoring. However, the existing K-RISS system suffers under several limitations. Objectives: This study aims to augment K-RISS with more detailed indicators and establish a severity standard that takes into account structural changes in the daily time series of K-RISS values. Methods: First, a Delphi survey was conducted to derive the required weights. Second, a control chart, commonly used in statistical process controls, was utilized to detect outliers and establish caution, attention, and serious levels for K-RISS values. Furthermore, Bai and Perron's method was employed to determine structural changes in K-RISS time series. Results: The study incorporated 'closeness to life' and 'sustainability' indicators into K-RISS. It obtained the necessary weights through a survey of experts for integrating variables, combining indicators by data source, and aggregating sub K-RISS values. We defined caution, attention, and serious levels for both average and maximum values of daily K-RISS. Furthermore, when structural changes were detected, leading to significant variations in daily K-RISS values according to different periods, the study systematically verified these changes and derived respective severity levels for each period. Conclusions: This study enhances the existing K-RISS system and introduces more advanced indicators. K-RISS is now more comprehensively equipped to serve as a risk warning index. The study has paved the way for an objective determination of whether the food safety risk index surpasses predefined thresholds through the application of severity levels.

A framework of multi layered database is proposed for the integrated operation of civil infrastructure information in this study. The multi-layered database is a logically integrated database composed of standardized information layers. The framework of multi-layered database is defined by three axes, national assets, lifetime, and data levels. The axis of national assets indicates civil infrastructures such as bridges, dams, tunnels and power plants that can be considered as national key structures. The axes of lifetime and data levels indicate the standardized information layers generated from the life-phase of civil infrastructure and the priority of data in the information layers, respectively. The standardized information layers are basically composed of reusable data sets defined by information models. A prototype of standard database for steel bridges is constructed based on the framework as a proof of concept. Demonstration examples such as data consistency check and automatic generation of a FEA model show that the proposed concept can assure the sustainable interoperability of civil infrastructure information as well as design information of steel bridges.

China's proposal of the CAFTA (China-ASEAN Free Trade Area) in 2001 prompted a great debate about whether China was a trade competitor of ASEAN, given their similarity in economic development levels and trade/export structures. That Beijing shifted its focus on economic cooperation from the international level to the regional level led to its proposal of the CAFTA. As the Framework Agreement (Framework Agreement on Comprehensive Economic Cooperation between China and ASEAN) showed, Beijing's careful consideration for four newer ASEAN members (Cambodia, Laos, Myanmar and Vietnam) intended not only to help all ASEAN members develop economically, but also to narrow the economic gap existing between them and the six old ASEAN members; in return, China was recognized as a full market economy, which it is not currently recognized within the framework of the WTO. The substantial rise in bilateral trade and the structural changes of the trade in goods between China and ASEAN member nations after 2001 proves that ASEAN benefited more from the CAFTA, particularly when the areas where ASEAN had the comparative advantages were designated as the priority cooperation areas between China and ASEAN. In sum, similarities existing in economic development levels and industrial structures between China and ASEAN made them natural economic competitors. However, closer studies of trade in goods of S1-7, S1-6 and S1-0 reveal that China acted as an increasingly complementary trade partner of ASEAN after 2001.

The surface sediments inside Hallim Harbor, one of the major harbors of Jeju Island, were sampled three times (June, September and December, 2001) and analyzed for 16 polycyclic aromatic hydrocarbons (PAHs), recommended by US-EPA as priority pollutants, to assess their distribution levels and to suggest their possible origins. The concentrations of PAHs ranged from 19 to 496 ng/g on a dry weight basis with a mean value of 245 ng/g, and the levels were low to moderate in comparison with other areas in the world. Based on comparisons of individual and total PAH concentrations with effects-based and equilibrium partitioning-based on sediment quality guidelines, the potential for the biological effects were expected to be low. The sedimentary PAHs may be correlated with organic carbon and mud contents to some extent. From the examinations of the four PAH origin indices, such as LMW/HMW (low molecular weight 2-3 ring PAHs over high molecular weight 4-6 ring PAHs), phenanthrene/anthracene ratio, fluoranthene/pyrene ratio, chrysene/benzo〔a〕anthracene ratio, it can be concluded that the sediment PAH contaminations were ascribed to both pyrolytic and petrogenic origins.

The 16 priority PAHs (Polycyclic Aromatic Hydrocarbons) designated by US Environmental Protection Agency were analyzed for some digested sludges from wastewater treatment plants in Korea. PAHs are an important group of organic contaminants present in sewage sludge due to their persistence and toxic potential. PAHs were extracted from freeze-dried sludges using a methylene chloride-methanol (2:1) mixture in a soxhlet extractor. The extracts were cleaned-up by silica gel/alumina combination column and subsequently fed into gas chromatograph/mass spectrometer (GC/MS) for determining PAH contents. The sum of the 16 PAHs in the sewage sludge varied from 534.8 to $5754.5 {\cal}ug/{\cal}kg$, dry wt.. In the sewage sludge, phenanthrene appears as the most abundant PAHs, followed by naphthalene, pyrene, fluoranthene. Source of the investigated sewage sludges relatively predominated pyrogenic. PAHs levels of sewage sludges in Korea appeared to be lower than those in other countries.

Purpose: This study examined medical college students' perception of euthanasia and analyzed whether there were significant differences in their perceptions based on their grade, religion, and economic situation. Methods: A questionnaire comprising items relating to students' knowledge about euthanasia, their economic situation relationships with patients, and the extent to which euthanasia would be allowed depending on the patient's condition. Results: Results by age and school year revealed there were no statistically significant differences concerning permissible levels of euthanasia. However, differences were found in the permissible levels of euthanasia according to changes in the patients' condition. Conclusion: It can be interpreted that students' personal values and religion had a great effect on the perception of euthanasia than the process of acquiring medical knowledge. The religion or values they have in your life affect your perception of euthanasia more than the process of acquiring and learning medical knowledge. The suffering of patients is the most important priority and it supports euthanasia on the grounds of relieving psychological distress for patients' families and the right of every patient to die gracefully. Nevertheless, considering the possibility of patient survival and euthanasia being used for murder, it is necessary to legislate the use of euthanasia and have the appropriate qualifications for its administration on patients.

Background and objective: This study seeks to investigate domestic agro-healing farm resources so that preliminary data can be obtained on the systematic provisions for agro-healing programs in order to improve service quality and to identify the quality of agro-healing policy services. Methods: For this study, owners of agro-healing facilities were asked 24 questions via an online survey. An importance-performance analysis (IPA) was conducted to identify service quality for each policy sector. Results: Respondents' satisfaction levels were low when compared to agro-healing farm owners' perceptions of the above-average importance of each sector. The results from the resource analysis of domestic agro-healing farms indicated that the main operational purposes of farms were, in descending order, experience (90.0%), healing (86.7%), and education (84.0%). With respect to the type of program that was operated, cultivating crops (horticultural therapy) was identified most frequently at 83.3%. Conclusion: As a result of this study, the resources possessed by agro-healing farms were identified. In addition, the results of the IPA analysis in terms of service quality are not as good as expected, and performance levels should be increased to improve this. The results of this study are expected to provide useful information not only to improve the quality of agro-healing services, but also to revitalize the agro-healing industry while developing a systematic agro-healing program.

Various carbon upcycling technologies have been proposed and are under development to achieve Korea's carbon neutrality target. Many chemical reactions are under development through various chemical reaction pathways, and different technological maturity levels are shown for each country and company. In this situation, it is essential to establish investment decisions such as research funds and human resources allocation through technological and economic analysis for close commercialization technologies and basic technologies with low technology readiness levels (TRL). Therefore, in this study, the technology development priority for developing carbon upcycling items was selected according to the domestic Carbon Capture & Utilization (CCU) technology roadmap using the stakeholder selection tool released by EU CarbonNext. As a result of the analysis, the TRL level of Korea's major carbon upcycling technologies was analyzed to be lower than that of other carbon resource technologies, and it was considered desirable to invest in mineral carbonization technologies among various candidate technologies.
