This study attempted to confirm the effects of a course on health and medical laws and regulations on ethical values, social responsibility, and political efficacy before and after the class. The participants were 59 fourth-year nursing students from a single university, and data were collected through a pre-post experimental design from September to December 2022. Data analysis was conducted using SPSS 27.0, including frequency analysis, means and standard deviations, and paired t-tests. The results of the study showed significant differences in students' ethical values(t=-6.728, p<.001), social responsibility(t=-5.842, p<.001), and political efficacy(t=-6.378, p<.001) after the course on health and medical laws and regulations. It appears that the development of programs and teaching methods that actively engage students in the health and medical laws and regulations course is necessary.

Southeast Asian cities like Manila, the Philippines, and Singapore have witnessed economic, political, and cultural changes over the years, especially after periods of colonization. States control their urban fabric-that is, its organization, planning, and design of cities-and thus dictate the flow of capital and forces of labor. Urban poor settlements, an offshoot of capital accumulation, are (re)moved around these cities in accordance with governing visions of development. For populations that are forced into changes brought about by urban development, practices of remembering are also controlled by dominant powers. These "monuments" are established in/as spaces to oblige an image of membership into a society ruled by such powers. Nevertheless, alternate sites of remembering counter these monumental spaces. This paper takes an interest in two novels that feature such places. Liwayway Arceo's Canal de la Reina (1972) and Suchen Christine Lim's The River's Song (2013) both figure rivers in Manila and Singapore, respectively. The eponymous river is the central axis of Canal de la Reina, entangled in class conflict and swift urban change in post-Commonwealth Manila. In The River's Song, the famous Singapore River provides a refuge for reminiscing about Singapore before the city-state's independence. Comparing these novels to what Filipino comparatist Ruth Jordana Pison calls fictional "counter-memory," we argue that their rivers remember personal and embodied experiences eliminated from hegemonic accounts of the city. Thus, they function as what we call "counter-monuments" for the urban poor marginalized in the history of the Philippines and Singapore.

The purpose of this study is a systematic literature review to investigate the effect of clinical judgment after simulation practice in nursing students in Korea. The research subjects were papers published from 2011 to February 2021, and the Korean database, KmBase, Korea Research Information (KISS), and Science and Technology Information (NDSL) were searched. ','Nursing debriefing' was searched. Out of a total of 279 studies, the final 3 literatures were selected. All three studies were non-randomized quasi-experimental studies, and the quality of the literature was confirmed. As a result of the study, it was confirmed that the debriefing after the simulation-based class showed statistically significant results for clinical judgment. In order to see the effect of simulation-based education, it is necessary to design a systematic interventional study in the future, and it can be suggested that field practice and a comparative study of simulation are necessary.

Most agricultural reservoirs were built between the 1940s and 1970s. Therefore, it is necessary to evaluate the current water supply safety, considering changes in water capacity, the water management, and environment in relation to the passage of time.. The design frequency of drought, the number of years areservoir needs to be able to withstand a drought phenomenon, foragricultural water resources in Korea is the 10-year drought. As the water supply system and water supply patterns change, it is necessary to establish a concept of water supply reliability, which refers to the stability of water supply. This study evaluated the water supply reliability of agricultural reservoirs based on the designed frequency. The previously designed frequency and water balance analysis were used to calculate and analyze reservoir storage capacity, water supply turnover, water supply amount, water supply potential, water utilization safety, and water supply reliability. As a result, Yongmyeon Reservoir was found to be stable in terms of water supply reliability, whereas Seongho and Yongpung Reservoirs were found to be unstable using all methods. In particular, when converting the water utilization safety and the water supply reliability to the frequency of drought, Seongho and Yongpung Reservoir were in the lowest class, with a frequency of drought less than four years. Thus, we recommend that the consideration of water supply reliability be included in the preparation of adaptive measures and water supply strategies as changes in environmental conditions continue to develop.

This thesis analyzes the formal characteristics of Dutch flower still life from the 17th century to the early 18th century and looks into the relevance with the Dutch art market from a macro perspective. The 17th Flower Still Life is to represent social hierarchy in that as the imported exotic, recherch items, the flowers were classified in the terms of their rarity and expensiveness. For this intriguing research, the subject is circumscribed to a vase of flowers, which is the quintessence of In the form of various Dutch Flower Still Life. Dutch society in the early 17th century was centered on the civilian class engaged in trade and commerce, which allowed them to purchase art works to show off their wealth, economic benefits and satisfaction of aesthetic tastes. Among them, the popularity of flower still life was related to the concentrated demand for rare flowers from the new continent. Accordingly, exact depiction and sense of the three dimensional manner were highly regarded in the early flower still life. For the tastes of the wealthy citizens who succeeded in business, the identity of flowers and the actual screen were considered as important. However, after the mid 17th century, economic growth in the Netherlands put an end, and the art market was also on a downward path. The demand class of flower still life has gotten farther away from the spirit of businessmen and has changed into city aristocrats who were stable rentiers. Their tastes laid emphasis on subjective sensibility, which meant that aristocratic, asymmetric, and dramatic chiaroscuro were preferred rather than being realistic. Furthermore, in the 18th century illusionistic realism was abandoned as an expression method of the planar characteristics and a new era in the floral still life was ushered with the reinforcement of decorative effect. From this perspective, it is not an exaggeration to say that romanticism, which is thought of as the beginning of Contemporary Art, originated from the aesthetic taste of Dutch civic culture.

In order to apply Interior Permanet Magnet Synchronous Motor(IPMSM) to the propulsion system of the railway transit, 110kW class IPMSMs with high-power density are designed as a concentrated winding model and a distributed winding model in this study. The concentrated winding model designed in this study is 6 poles/9 slots and the distributed winding model is 6 poles/36 slots. In general, the eddy current losses in the permanent magnets of IPMSM are caused by the slot harmonics. The thermal demagnetization of the magnet by the eddy current losses at high rotational speed often becomes one of the major problems in the IPMSM with a concentrated windings especially. A design to reduce eddy current losses in permanent magnet design is important in IPMSM for the railway vehicle propulsion system which requires high-speed operation. Therefore, a method to devide the permanent magnet is proposed to reduce the eddy current losses in permanent magnet in this study. Authors analyze the variation characteristics of the eddy current losses generated in permanent magnet of the concentrated winding model by changing the number of the division of the permanent magnets.
