  • During December 2022, the northeast monsoon, which dominates the south and the Gulf of Thailand, had significant rainfall that impacted the lower southern region, causing flash floods, landslides, blustery winds, and the river exceeding its bank. The Golok River, located in Narathiwat, divides the border between Thailand and Malaysia was also affected by rainfall. In flood management, instruments for measuring precipitation and water level have become important for assessing and forecasting the trend of situations and areas of risk. However, such regions are international borders, so the installed measuring telemetry system cannot measure the rainfall and water level of the entire area. This study aims to predict 72 hours of water level and evaluate the situation as information to support the government in making water management decisions, publicizing them to relevant agencies, and warning citizens during crisis events. This research is applied to machine learning (ML) for water level prediction of the Golok River, Lan Tu Bridge area, Sungai Golok Subdistrict, Su-ngai Golok District, Narathiwat Province, which is one of the major monitored rivers. The eXtreme Gradient Boosting (XGBoost) algorithm, a tree-based ensemble machine learning algorithm, was exploited to predict hourly water levels through the R programming language. Model training and testing were carried out utilizing observed hourly rainfall from the STH010 station and hourly water level data from the X.119A station between 2020 and 2022 as main prediction inputs. Furthermore, this model applies hourly spatial rainfall forecasting data from Weather Research and Forecasting and Regional Ocean Model System models (WRF-ROMs) provided by Hydro-Informatics Institute (HII) as input, allowing the model to predict the hourly water level in the Golok River. The evaluation of the predicted performances using the statistical performance metrics, delivering an R-square of 0.96 can validate the results as robust forecasting outcomes. The result shows that the predicted water level at the X.119A telemetry station (Golok River) is in a steady decline, which relates to the input data of predicted 72-hour rainfall from WRF-ROMs having decreased. In short, the relationship between input and result can be used to evaluate flood situations. Here, the data is contributed to the Operational support to the Special Water Resources Management Operation Center in Southern Thailand for flood preparedness and response to make intelligent decisions on water management during crisis occurrences, as well as to be prepared and prevent loss and harm to citizens.

  • Buildings that are more than 10 years old generally have considerable repair and replacement costs due to the rapid deterioration of their systems. For public buildings in particular, which have national and social significance, considerable effort is required not only to ensure a long life cycle and safety but also to minimize the overall public expense. Along with increasing repair and replacement requirements, however, there have been problems related to the establishment of an accurate facility management budget. To address these concerns, a repair and replacement cost management system was constructed. This system manages both invested maintenance and forecast costs to establish a reasonable repair and replacement planning process and budget. The effectiveness of the system was verified through a pilot test targeting one of public Corporation (K).

  • This paper introduces the public-oriented e-Hub construction for strategic alliances in the B2B virtual community. The public-oriented e-Hub can link with all participating Internet firms on the basis of their business models, and consequently help them share their core competence, management resources, and so on. Based upon this perspective, this paper presents the procedures corresponding with social network analysis for strategic alliances of small and medium internet firms. In addition, this paper tries to analyze the relationships among degree of competition, potential of strategic alliance, and financial performance. The results show that the firms with more easily accepting various strategic alliances make higher financial performance under more competitive environment. This suggests that strategic alliances through the public-oriented e-Hub in the B2B virtual community provide the internet firms with various opportunities.

  • In recent years, many studies on the public library services for individual vulnerable groups have been performed in Korea. From the standpoint of public libraries with limited human and physical resources, however, all proposed alternatives are difficult to accommodate due to overload and in an integrated perspective, the several alternatives have a logical contradiction and possibility of realistic conflicts. Focusing on these facts, this study proposed an integrated direction and strategic plan to strengthen knowledge and information services of public libraries for five vulnerable classes, ie., the disabled persons, multi-cultural families, the elderly, rural residents, basic living subsidies.

  • The energy used in Korea is strongly dependent on that produced by foreign countries. Accordingly, saving energy is more important than ever, because of the rise of international oil prices and depletion of oil resources. The development of energy efficient buildings is required especially for public buildings in Korea. In this study, the energy use of public buildings is identified. Then, the analysis of energy usage through regional offices in Busan City offers energy saving measures for public buildings.

  • Mankind has made traditional use of various ocean resources in such several forms as fish, plants food, means of transportation, and military purpose, followed by the recent exploitation of offshore subsoil or sea-bed minerals, energies, and utilization of ocean space. These available ocean resources come from the marine natural environment which has a distinct feature in view of the relationship between human wants and their capacity to meet them. Though these socially basic resources however bring forth the so-called scarcity or differential rent, their communal nature of ownership dissipates free gifts of nature endowed to society as a whole. Thus to maximize these rents and social welfare thereof, rents should be secured and preserved through a well-defined arrangements of property-ownership as well as appropriate comparison of competing uses of marine resources, taking full cognizance of their irreversible adverse effects of a specific choice on the alternatives. Here I showed the sources of rent yielded from the multiple uses of navigation, fishery, mariculture, minerals, and recreation site, and also summarized the presently widely-known analytic tool to measure these rents with emphasis on due care of the telescopic faulty of the appraiser in charge, viewed from the communal point, Finally, as communal property is in strict sense owned by the public at large, notwithstanding the restricted communal ownership at government or local governments control, effectiveness of competition I expect should be kept while transferring claims of these resources from the legal owner to private enterprise as well as while extracting their rent by her. In particular, various national or social objectives look forward to tile maximization of social efficiency. Discretionary system in noncompetitive method thus, is exceptionally suggested because of probable suspicion from the public whether these resources are transferred as a give away or not in discretion. And these realized rent payments, I propose, should be wisely taken advantage of in advancement of scientific research in marine nature to bring an incremental rent therefrom successively.

  • This study aims to examine the effect of a change of leadership on internal environment and organization effectiveness and suggest measures on effective organizational management by analyzing a change of leadership before and after 2nd generation management. There was analysis of a difference of leadership type, organizational structure, organizational culture, management resources, job satisfaction, and organizational commitment between the period of the founders and the period of 2nd generation successors by collecting data from employees of 6 hospitals in Seoul. Also there was analysis of the effect of a change of leadership on internal environment and organizational effectiveness. According to the analysis, it was demonstrated that the factor affecting job satisfaction during the period of the founder was complexity of organizational structure, and there were no factors affecting organizational commitment. In contrast, during the period of the 2nd generation successors, it was revealed that transformational leadership, centralism of organizational structure, and human resources of management resources affect job satisfaction, and transformational leadership, complexity of organizational structure, hierarchical culture of organizational culture, and human resources of management resources affect organizational commitment. Further, after the succession from the founders to 2nd generation successors, as transformational leadership increased, job satisfaction rose, and as developmental culture was reinforced and human resources increased, organizational commitment was heightened. Furthermore, as transformational leadership increased and developmental culture was reinforced, organizational commitment was heightened. Namely, as transformational leadership was reinforced resulting from the succession to 2nd generation, employees' job satisfaction and organizational commitment increased, with circumstances aiming for the actual change.

  • The experience of many countries strongly suggests that bad governments and institutions have been a serious, if not the most serious, obstacle to economic growth and industry-structural adjustments. All public sectors pursue a mix of both predatory and productive activities-bad governments emphasizing the former, while good governments finding a way of promoting the later. In fishery public policy studies, much confusion exists about the roles of policy illustration and prescription. In general fishery public sectors involve collective actions by numerous individuals under conditions of uncertainty, complexity, bounded rationality, and imperfect information structure. All collective fisheries action organizations consist of a center(e.g., government), which leads fishery group actions, and peripheral participants(e.g., fishermen), which are controlled by the government. A paradigm is developed that gives both theoretical and empirical meaning to the constitutional determination of fisheries political preference function or fishery public sector governance structures. Three relevant spaces are specified: policy instrument, results, and constitutional. The collective-choice rules of the constitutional space structure the tradeoff between public and special fishery interest groups. Fishery public sectors seeking sustainable reductions in wasteful rent-seeking fishing activities should select constitutional principles and institutional structures that tend to promote resource sustainability. In particular, the effects of internal and external events on fisheries may result in a greater or lesser concentration of interest group power. Thus, the structure of the fishereis political power must be assessed in any prescriptive evaluation of alternative fishery governance weights.
