The purpose of this study is to evaluate on the applicability of Load Duration Curve (LDC) method using Maintenance of Variance Extension types 2 method and sampling data for efficient total maximum daily loads at the Nakbon-A unit watershed in Korea. The LDC method allows for characterizing water quality data such as BOD, TOC, T-N and T-P in this study at different flow regimes(or quarters). BOD usually exceeded the standard value (exceedance probability 50%) at low flow zone. On the other hand, TOC, T-N, T-P usually exceeded the standard value at dry and low flow zone. Seasonally all water quality variables usually exceeded the standard value at Q1(Jan-Mar) and Q2(Apr-Jun) zones. Improvement of effluent control from wastewater treatment plants are effective to improve BOD and T-P.

Residential environment is not only the physical aspects affected by the unique characteristics of the residents, social, economic, cultural, etc. are closely related to many environmental factors. This research is based on choice attribute theory that substantially explains how housing choice attributes affect loyalty via image, perceived value in Secho. This paper investigate empirically relationship between selection properties of residential environment and loyalty, moderating effect of image and perceived value. Results were computed using SPSS 20.0 statistical analysis programs. The results are summarized as follows. First, The elements of choice attribute are divided into six factor, such as regional reputation, green environment, convenience, property value, safety, housing status. In the results of the analyses, housing choice properties gives a positive influence to the loyalty. Second, testing its mediating role, I use the three regression equation models by Baron and Kenny. When the mediator effect of image, perceived value was represented, the effect of image and perceived value was statistically significant. Thus, the mediating role of image and perceived value was supported. It means the higher image and perceived value can enhance loyalty of Secho.

The value of rice-fields is being graded down in Korea because it has been estimated only from the size. The purpose of this study is to suggest a management plan in which the location and the size of valuable rice-fields for conservation are based on the results of appraising the worth of ecosystem services of rice-fields in Chungcheongnam-do region. The study is as follows; (1)selecting the indicators for evaluating the ecosystem services of rice-fields considering both general functions and special functions in the regional environment conditions, (2)classifying the grades of rice-fields in ecosystem service values, (3)suggesting the location and the size of valuable rice-fields for conservation, (4)calculating the total economic value of the ecosystem services of rice-fields. The results of this study are that the valuable rice-fields' locations for conservation are the grade I rice-fields and their total area is 100,000ha. Also, the value of the ecosystem services of rice-fields in Chungcheongnam-do region was equivalent to 32.8 trillion won. This amount is over 18 trillion won more than the amount obtained if the total rice-fields in Chungcheongnam-do region were to be transformed to other land-use types. The value of ecosystem services should be considered in the future when appraising the worth of rice-fields, and methods of estimating the ecosystem services of rice-fields need to be developed with a more objective and suitable index.

Purpose : This study aims to assess the extent of work value, psychological ownership, the nursing work environment, and retention intention, examine the correlation between these variables, and identify the factors that influence retention intention. The goal is to provide foundational data to enhance retention intention. Method : The study involved 159 nurses employed at a tertiary general hospital and a general hospital. Data were gathered through structured questionnaires and analyzed using an independent t-test, one-way ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression analysis with a simultaneous stepwise method, all conducted using the SPSS 26.0 software. Results : The intention to remain in the profession was found to have a positive correlation with work value (r = .45, p < .001), psychological ownership (r = .37, p < .001), and the nursing work environment (r = .27, p = .001). Significant factors influencing the intention to stay included total clinical career (𝛽 = .17, p = .016), work value (𝛽 = .38, p < .001), and psychological ownership (𝛽 = .19, p = .020). These variables accounted for 24.1% of the variance in the intention to remain in the profession (F = 17.71, p < .001). Conclusion: To enhance the intention of hospital staff to remain in their positions, it is crucial to identify and bolster positive psychological competencies, such as a sense of work value and psychological ownership.

Damage to the natural environment is becoming increasingly complex in modern society, expanding to impact not only the environment but also society and the economy. Various systems and policies based on sustainability have been promoted internationally. Legal systems and policies based on evaluation systems such as land environment assessment and urban ecological status maps, have been implemented in Korea. However, most of Korea institutions and policies related to the natural environment have been directed toward the conservation of the natural environment, and restricted to in simple theoretical frameworks with various limitations. Therefore, this study analyzed the definition and value of the natural environment for a fundamental conceptual approach to the valuation of the natural environment. Based on this, we modeled the policy process for a flexible evaluation system suitable for the actual situation of Korea natural environment through a review of the integration of environmental policy proposed in Europe.

It is desirable for autonomous robot systems to possess the ability to behave in a smooth and continuous fashion when interacting with an unknown environment. Although Q-learning requires a lot of memory and time to optimize a series of actions in a continuous state space, it may not be easy to apply the method to such a real environment. In this paper, for continuous state space applications, to solve problem and a triangular type Q-value model\ulcorner This sounds very ackward. What is it you want to solve about the Q-value model. Our learning method can estimate a current Q-value by its relationship with the neighboring states and has the ability to learn its actions similar to that of Q-learning. Thus, our method can enable robots to move smoothly in a real environment. To show the validity of our method, navigation comparison with Q-learning are given and visual tracking simulation results involving an 2-DOF SCARA robot are also presented.
