This case report is a unique case of solar retinopathy following antidepressant-induced mydriasis and highlights the need for comprehensive ophthalmic evaluation in patients treated with medications having mydriatic effects. A 49-year-old female patient who had received long-term antidepressant therapy presented with bilateral visual impairment after prolonged sun exposure. Fundoscopy confirmed solar retinopathy, which was attributed to drug-induced mydriasis. Medication adjustments and sun protection strategies led to full visual recovery, underscoring the importance of interdisciplinary awareness. This case emphasizes the challenges associated with the simultaneous management of psychiatric and ophthalmic conditions and highlights the need for routine ophthalmic evaluation of patients prescribed antidepressants with reported ocular side effects.

This study aimed to develop a digital thesaurus dedicated to cataloging the traditional common culture of the Greater Mekong Subregion. The process followed a meticulous seven-step methodology, including scoping, vocabulary collection, knowledge structure analysis, relationship delineation, related word adjustments, list validation, and evaluation. Leveraging principles from knowledge organization, thesaurus construction, and digital platform development, the TemaTres web application emerged as the primary tool for constructing this thesaurus. The study's results showed that 2,042 principal words related to the traditional common culture of the Greater Mekong Subregion were compiled and classified into terms for each of the seven deep levels. Each term was accompanied by essential metadata, including broader and narrower terms, related terms, cross-references, and scope notes. This rich dataset empowered semantic search capabilities across diverse applications and web services, providing access to knowledge pertaining to the traditional common culture of the Greater Mekong Subregion and contributing to a deeper understanding of this cultural domain.

This paper attempts to identify key determinants of long run movements of real M2 by using the Johansen procedure for estimating and testing cointegration relations. It turns out that the real M2 equation has been stable over the long run despite rapid changes in financial structure since 1975. Moreover, the real M2 equation can be reduced to a velocity equation with the opportunity cost variable, expected inflation less the weighted average rate paid on M2 deposits, being the key determinant. However, it does not work to use a market interest rate such as the yield on corporate bonds in place of expected inflation for calculation of the opportunity cost. In the U.S., a market interest rate can be used, but not in Korea. Presumably, two somewhat different reasonings can be used to explain this result. One is that the yield on corporate bonds may not adequately reflect the inflationary expectations due to regulations on movements in interest rates. The other is that M2 deposits are not readily substitutable with such assets as corporate bonds because of market segmentations, regulations, and so on. From the policymaker's point of view, this implies that the inflation rate is an important indicator of a policy response. On the other hand, policymakers do not regard movements of the yield on corporate bonds as an important policy indicator. Altogether, the role of interest rates has been quite limited in Korea because of incomplete interest rate liberalization, an underdeveloped financial system, implementation procedures of policy measures, and so on. The result that M2 velocity has a positive cointegration relation with expected inflation minus the average rate on M2 implies that frequent adjustments of the regulated rates on M2 will be necessary as market conditions change. As the expected inflation gets higher, M2 velocity will eventually increase, given that the rates on M2 do not change. This will cause higher inflation. If interest rates are liberalized, then increases in market interest rates will result in lagged increases in deposits rates on M2. However, in Korea a substantial portion of deposit rates are regulated and will not change without the authority's initiatives. A tight monetary policy will cause increases in a few market interest rates. But the market mechanism, upward pressure for interest rate adjustments, never reaches regulated deposit rates. Hence the overall effects of tight monetary policy diminish considerably, only causing distortions in the flow of funds. Therefore, frequent adjustments of deposit rates are necessary as market conditions such as inflationary expectations change. Then it becomes important for the policymaker to actively engage in adjusting regulated deposit rates, because the financial sector in Korea is not fully developed.

The research was performed responding to the growing needs of Korean foster care programs. It deals specifically with the people who voluntarily provide foster care despite the lack of Government support. The research has also made an effort to understand how the foster parents perceive their parent roles for the foster children. According to the research results based on the parents from the H foster care center, it showed that foster parents generally come from higher educational backgrounds compared to their equivalent age group and also similar or even higher income levels than the average family residing in an urban area. Conclusively, their traits in socio-demographic factors is said to be homogeneous. The research also focused on examining the role perceptions of Korean foster parents. The foster parents were well aware and educated on the significance of the children's psychological adjustments. However, the research recognized some role responsibilities that the parents failed to understand. Hopefully the foster care centers will take on such responsibilities and contribute in helping the parents realize their insufficiencies. Based on the results of the research, the researcher was able to recognize the important issues involved in the recruitment, selection, and education process for the foster parents. Additionally, new role adjustments are necessary among both foster parents and foster centers.

Main cable of a suspension bridge is the important member which shows the overall structure integrity at bridge completion. Configuration of main cable is a free hanging state at cable erection completion and is different from that at bridge completion supporting the dead loads such as hanger, girder, and so on. Accordingly, the configuration control under cable erection is considerably significant because the configuration at cable erection completion has direct influence on that at bridge completion. That is performed by sag adjustments at center, side span and tension adjustments at anchor span. The former needs the sag sensitivity which represents the control quantity of strand length corresponding to that of sag. The latter requires the tension sensitivity which shows the change of strand tension according to that of strand temperature. In this study, the fundamental equations of cable were derived with the assumption of either catenary or parabola shape, the differential-related equations using chain rule on horizontal tension were drawn from those and finally the estimation methods of the sag / tension sensitivity were proposed from both those. The nonlinear numerical analysis flow charts of sag sensitivity based on the catenary equations were proposed and the sag sensitivities grounded on the differential-related equations were compared with the results using them for various parameters of sag change. Also, considering the combinations of sag change parameters, the calculation method of the final variation for the cable sag was suggested. For the real suspension bridge under construction with PPWS method, the sag/tension sensitivity were estimated considering the construction conditions like the change of PPWS length, PPWS temperature, bridge span, etc.. We hope that this study will be a systematic guideline for the configuration control under main cable erection and improved highly by field verification in the real bridge site.

Objectives: This study aims at analyzing relationships between college life adoption, self-efficacy, and self-esteem in undergraduates majored in dental hygiene to explore the ways to prevent college dropouts and promote and support college life adaptation. Methods: This study was made with the use of a self-completion questionnaire with 200 undergraduate students, aged 19 or older, majored in dental hygiene in three colleges situated in Gyeonggi-do, from September 02 to 11, 2019. The results were analyzed using the SPSS Program Version 22.0. Results: First, the degree of college life adaptation in undergraduates majored in dental hygiene was found to be the highest, in those who were under 20 years old and first grade, decided to major in dental hygiene because of 'its aptitude and future career', and graduated from general high school and with a high economic level. Second, the degree of college life adoption was found to be the highest in the third grade in terms of social adaptation, and of the first grade was higher than the second grade. Third, as for the degree of attachment to college, it was revealed to be the highest in those decided to major in dental hygiene because of 'its aptitude and future career', and the degrees of academic adaptation, emotional adaptation, and attachment to college were found to be higher in general high school graduates than specialized high school graduates. Fourth, the factor having the most significant influence on college life adaptation in undergraduates majored in dental hygiene was found to be self-efficacy, followed by self-esteem and economic level. Conclusion: From these results, it is possible to assume that when developing programs to prevent college dropouts in undergraduates majored in dental hygiene, it should consider their high schools, school grades, and motivations to decide to major in dental hygiene. In addition, in order to take an educational approach to raise self-esteem and self-efficacy in career decision making to raise the degree of college life adaptation.

This paper presents a procedure to recover sea surface heights (SSH) and free-air (FA) gravity anomalies from dense satellite altimeter SSH data with enhanced accuracies over the full spectrum of the gravity field. A wavenumber correlation filtering (WCF) of co-linear SSH tracks is developed for the coherent signals of sub-surface geological masses. Orbital cross-over adjustments with bias parameters are applied to the filtered SSH data, which are then separated into two groups of ascending and descending tracks and gridded with tensioned splines. A directional sensitive filter (DSF) is developed to reduce residual errors in the orbital adjustments that appear as track patterned SSH. Finally, FA gravity anomalies can be obtained by the application of a gradient filter on a high resolution estimate of geoid undulations after subtracting dynamic sea surface topography (DSST) from the SSH. These procedures are applied to the Geosat Geodetic Mission (GM) data of the southern oceans in a test area of ca. $900km\;\times{1,200}\;km$ to resolve geoid undulations and FA gravity anomalies to wavelengths of-10 km and larger. Comparisons with gravity data from ship surveys, predictions by least squares collocation (LSC), and 2 versions of NOAA's predictions using vertical deflections illustrate the performance of this procedure for recovering all elements of the gravity spectrum. Statistics on differences between precise ship data and predicted FA gravity anomalies show a mean of 0.1 mgal, an RMS of 3.5 mgal, maximum differences of 10. 2 mgal and -18.6 mgal, and a correlation coefficient of 0.993 over four straight ship tracks of ca. 1,600 km where gravity changes over 150 mgals.

This paper proposes a new design method of neuro-FLC by the Lamarckian co-adaptation scheme that incorporates the backpropagation learning into the GA evolution in an attempt to find optimal design parameters (fuzzy rule base and membership functions) of application-specific FLC. The design parameters are determined by evolution and learning in a way that the evolution performs the global search and makes inter-FLC parameter adjustments in order to obtain both the optimal rule base having high covering value and small number of useful fuzzy rules and the optimal membership functions having small approximation error and good control performance while the learning performs the local search and makes intra-FLC parameter adjustments by interacting each FLC with its environment. The proposed co-adaptive design method produces better approximation ability because it includes the backpropagation learning in every generation of GA evolution, shows better control performance because the used COG defuzzifier computes the crisp value accurately, and requires small workspace because the optimization procedure of fuzzy rule base and membership functions is performed concurrently by an integrated fitness function on the same fuzzy partition. Simulation results show that the Lamarckian co-adapted FLC produces the most superior one among the differently generated FLCs in all aspects such as the number of fuzzy rules, the approximation ability, and the control performance.

First, during Jin and Sui dynasty, It is possible that the theory of the contraindications of needling according to whereabouts of the self-guarding energy and demon, affected considerably to the practise of acupuncture and moxibustion, but the detailed situations are unknown. Only, there are some records of the process about circulation of the self-guarding energy and demon by a periodicity of 30 days in the "The prescriptions of Fan-Wang" by Fan-Wang in Jin dynasty and "Hua Tuo Fa" by a nameless person. But the theory differs form the theory of "Huang Di Xia Mo Jing" in some respect. Also, there is the contraindications of needling to abscesses according to whereabouts of the self-guarding energy and demon by every year in the "Liu Juan Zi Gui Yi Fang". but the book has no specific rule in use. Second, during Tang dynasty there were a vasty development on the contraindications of needling according to whereabouts of the self-guarding energy and demon. In the medical works in Tang dynasty, the contents of the contraindications of needling are included in various periodicities and directions such as 12 regions according to the year, 9 regions according to the year, 9 palaces in the body according to the year, whereabouts of the self-guarding energy and demon according the four seasons, every 10 days, every 12 days, every 30 days, and every dozen hours. Also, during Tang dynasty period, the contraindications of needling according to whereabouts of the self-guarding energy and demon were formulated through several adjustments and modifications by many medical scholars. Third, the period between Jin and Tang dynasty, because of historical situations, the documentary data are insufficient in the study of the recommendations and contraindications on the acupuncture, moxibution, and herb medicine according to the specific days and times. And the detailed informations are unknown. Only but once in Tang dynasty the considerable and theoretical adjustments were performed in the "Qian Jin Yao Fang". In Song dynasty, there were also much theoretical fluctuations in the study of the choice of the favorable or the injurious days and times or directions in the acupuncture, moxibustion and the prescription and processing of herbs. Fourth, contraindications on the acupuncture, moxibution, and herb medicine did not include acute and serious disease among the effect province, only include chronic and not serious disease. If the doctors had treated a surgical patients and abscess patients with deeply attached contraindications on the acupuncture, moxibution, and herb medicine, the patients would have became more serious. So the theory was not used for treatment by doctor.

The article identifies the problem of monitoring the quality of higher education in three main areas, which are comparative pedagogical systems of education. The first direction is determined by dissertation works, the second - monographs and textbooks, and the third reveals scientific periodicals. According to its internal structure, monitoring the quality of education combines important management components identified in the article (analysis, evaluation and forecasting of processes in education; a set of methods for tracking processes in education; collecting and processing information to prepare recommendations for research processes and make necessary adjustments). Depending on the objectives, three areas of monitoring are identified: informational (involves the accumulation, structuring and dissemination of information), basic (aimed at identifying new problems and threats before they are realized at the management level), problematic (clarification of patterns, processes, hazards, those problems that are known and significant from the point of view of management). According to its internal structure, monitoring the quality of education combines the following important management components: analysis, evaluation and forecasting of processes in education; a set of techniques for tracking processes in education; collection and processing of information in order to prepare recommendations for the development of the studied processes and make the necessary adjustments. One of the priorities of the higher education modernization program during the COVID-19 pandemic is distance learning, which is possible due to the existence of information and educational technologies and communication systems, especially for effective education and its monitoring in higher education. The conditions under which the effectiveness of pedagogical support of monitoring activities in the process of distance learning is achieved are highlighted. According to the results of the survey, the problems faced by higher education seekers are revealed. A survey of students was conducted, which had a certain level of subjectivity in personal assessments, but the sample was quite representative.
