  • This study aimed to assess the causality of different climate variables on the production of whole crop maize (Zea mays L.; WCM) in the central inland region of the Korea. Furthermore, the effect of these climate variables was also determined by looking at direct and indirect pathways during the stages before and after silking. The WCM metadata (n = 640) were collected from the Rural Development Administration's reports of new variety adaptability from 1985-2011 (27 years). The climate data was collected based on year and location from the Korean Meteorology Administration's weather information system. Causality, in this study, was defined by various cause-and-effect relationships between climatic factors, such as temperature, rainfall amount, sunshine duration, wind speed and relative humidity in the seeding to silking stage and the silking to harvesting stage. All climate variables except wind speed were different before and after the silking stage, which indicates the silking occurred during the period when the Korean season changed from spring to summer. Therefore, the structure of causality was constructed by taking account of the climate variables that were divided by the silking stage. In particular, the indirect effect of rainfall through the appropriate temperature range was different before and after the silking stage. The damage caused by heat-humidity was having effect before the silking stage while the damage caused by night-heat was not affecting WCM production. There was a large variation in soil surface temperature and rainfall before and after the silking stage. Over 350 mm of rainfall affected dry matter yield (DMY) when soil surface temperatures were less than 22℃ before the silking stage. Over 900 mm of rainfall also affected DMY when soil surface temperatures were over 27℃ after the silking stage. For the longitudinal effects of soil surface temperature and rainfall amount, less than 22℃ soil surface temperature and over 300 mm of rainfall before the silking stage affected yield through over 26℃ soil surface temperature and less than 900 mm rainfall after the silking stage, respectively.

  • The Korea Environmental Impact Assessment (EIA) system was introduced in 1977 through the Environmental Conservation Act. It has progressed through many laws and regulations promoting the balance between development and conservation, and functioning as a Preventitive environmental policy. Despite the efforts to minimize environmental damage from development and to uplift social awareness of environmental preservation, deficient impartiality and objectivity in completing and investigating environmental assessments, there have continously existed conflicts among related stakeholder, neglecting arrangements and ineffectiveness of public participation. This research present EIA obstacles and analyzes the overall status of the EIA through surveys from related experts. On the basis of this research, the actual complications regarding the developer, public participation, examiner and consultant are brought about. Also, remedies are proposed to ensure effective EIAs and restore confidence in them.

  • The main purposes of this study are to find the causality among residents' loyalty to an environmental festival and its influential factors and, based upon the findings, to explore environmental festivals' developmental vision with special reference to Hampyung Butterfly Festival. Under these aims, this study applies structural equation modeling(SEM). The structural model for SEM analysis is composed of four independent variables which consist of residents' attachment(RA) to their region where its own environmental festival is provided, residents' participational intention(RP) to the festival, the economic effects(EE) of the festival, and the communication(CM) between the residents and the festival providers, one intermediate variable, residents' satisfaction(RS) from the festival, and one final dependent variable, residents' loyalty(RL) to the festival. The causality among these variables is hypothesized as follows; Among the independent variables, RP, EE, and CM have effects only on RS and RA has an effect on both RS and RL. And RS has an effect on RL. The facts found from the SEM are summed up as follows; First, (1) RP and CM turn out to have statistically significant effects on RS, (2) RA is confirmed to have a statistically very significant effect on both RS and RL, and (3) RS is also proved to show a statistically very significant effect on RL. Second, the total effects on RL of independent variables are stronger in the order of RA, CM, and RP. Third, EE seems to have no effect on RS, consequently no effect on RL, either. The reason why EE has no effect looks like to be due to environmental festivals' peculiar features. These findings offer the following suggestions for the future of environmental festivals in the part of festival providers. Firstly, to be successful in the festival, they have to provoke RL above all. Second, to do so, they need to encourage RA, CM, and RP in the mentioned order in the long run. Third, but for a short period, they had better concentrate upon promoting RS.

  • The purpose of this study is to investigate the causality between life satisfaction and domain satisfactions. For this study, data were collected from 207 respondents. They completed World Health Organization Quality of Life Assessment Instrument - Brief (WHOQOL-BREF) which is self-report questionnaire asking about life satisfaction and domain satisfactions. For data analysis, the verification procedure by autoregressive crosslagged modeling of structural equation was used. The analysis results of measures showed the causal relation between the two variables, that is, domain satisfactions acted as cause of life satisfaction. There were discussions on the issues about the analysis method of the autoregressive crosslagged modeling, the implications of the results, and the limits of the research. This study ascertained the intervention direction between life satisfaction and domain satisfactions to promote life satisfaction.

  • Three cases of simple exanthematous eruption were suspected during Sumsu (Bufonis Venenum) pharmacopuncture (SP) topical anesthesia for acupotomy. Patients had skin rash with pruritus on both ankle, posterior neck, and left shoulder after 11, 12, and 7 times of SP treatment, respectively. There were no cases of systemic manifestations or changes in vital signs. As a result of using the World Health Organization-Uppsala Monitoring Centre (WHO-UMC) causality assessment, all the cases were evaluated as 'unlikely'. However, the results of using the Korean algorithm for assessing the causality of drug adverse reactions version 2.0 were evaluated as 'possible'. This report is the first case report on adverse events suspected of occurring after SP treatment. Although the causal relationship between suspected intervention and the adverse event is not clear, there was a difficulty in completely excluding the possibility. Additional safety studies will be required to make SP more widely available.

  • Purpose: In the current era of rapid development of the information and communication technologies (ICT) sector, the formation of an effective regulatory approach is important. There are some methodological shortcomings and difficulties in the approach system of international organizations that assesses the level of application of ICT in various areas in terms of quantity and quality. The basic element of economic growth differs according to the economic conditions prevailing in the period and the country. While the agricultural sector plays an active role in economic growth or development in an underdeveloped country, in a developed country, capital-intensive and even technology-intensive production is the main element of economic growth. From this point of view, the contribution of information and communication technologies (ICT) to Azerbaijan's socio-economy for the period between 2010-2020 will be examined. Research design and methodology: The unit root test and Granger causality test were applied by taking the CDPPC per Capita, Employment, and Unemployment Rate from the social-o-economic data as the dependent variable, fixed and mobile phone usage and internet usage as the independent variables. The principal results: According to the results obtained; It has been determined that the use of ICT positively affects the socio-economic economic situation.

  • Adverse drug reactions (ADR) may result in increased hospital admissions, morbidity and mortality, adding extra cost to healthcare expenditures. Thus, it is critical to activate ADR monitoring and reporting program in tertiary hospitals in developing countries such as Korea. This study was performed to identify the types of ADR being reported in a tertiary hospital, Samsung Medical Center, and to find out the ways to improve current ADR monitoring system. Of 464 ADR reports submitted to the pharmacy department during the 6-month survey period, $97.8\%$ of the reports were from out patient and $48.5\%$ were from patients aged between 50 and 60. The medical department with the highest frequency in ADR reporting was Internal Medicines $(35.6\%)$. The most common ADR manifestations were gastrointestinal complaints $(43.4\%)\;and\;75\%$ of the reported cases were mild in their severity. The most common drugs suspected of causing ADR were CNS drugs which accounted for $32.8\%$. In terms of causality assessment, $85.1\%$ of the reports were probable cases by WHO causality assessment criteria. In regards to sources of report, $75.6\%$ of ADR were reported by physicians and $24.4\%$ by nurses. There were no ADR reported by pharmacists. In conclusion, there is an urgent need to improve ADR monitoring system for inpatient and to motivate pharmacist involvement in ADR monitoring and reporting in Korea.

  • In the course of insurance claim administration, medical experts' opinions are called medical claim reviews. They are classified into two main categories: medical verification and counsel for claim staff. Medical verification compare between product coverage and the insured's physical condition. Medical counsel for claim staff is advice for claim staff when they have a question about medical knowledge to make a claim decision. A common example of medical verification is insurance coding of pituitary apoplexy. Some clinicians have insisted that the ICD coding of pituitary apoplexy is l63 of cerebral infarction, but the exclusion criteria of I code show that neoplasm is coded as C00 to D48. Thus, pituitary apoplexy must be coded as D33. An example of medical counsel for claim staff is interpretation of some medical conditions. It is divided into UCR(usual, customary, and reasonable) assessment, assessment of causality, and so on. Disability evaluation is another subject of medical counsel for claim staff. The final claim decision must be made by claim staff because only the claim staff have the authority of claim decision. Medical claims review is only an expert's opinion.

  • Objective: To compare adverse event reporting patterns between ethical-the-counter and over-the-counter drugs from community pharmacies and outpatient settings. Methods: We conducted a descriptive study using the adverse event reporting database, wherein data were collected from the regional pharmacovigilance centers of the Korean Pharmaceutical Association between January 1, 2016 and December 31, 2016. The reported drugs were classified into either ethical-the-counter or over-the-counter drugs, and we compared the distribution of patient age and gender, frequent adverse events and medications, serious adverse events, and causality assessment results, where causality assessments were performed according to the World Health Organization-The Uppsala Monitoring Centre's system. Results: We included 17,570 reports (75,451 drug-adverse event pairs). Ethical-the-counter and over-the-counter drugs accounted for 81.4% and 18.6% of the total adverse event reports, respectively. The use of over-the-counter drugs was higher in females and patients aged <18 years, whereas the use of ethical-the-counter drugs was higher in those aged >65 years. Alimentary tract and metabolism drugs, and respiratory system drugs were the most frequent ethical-the-counter and over-the-counter drugs, respectively. From causality assessment results, "possible" (75.4%) was the most commonly assigned category for ethical-the-counter drugs, while "possible" (44.0%) and "unlikely" (47.7%) were the most common categories for over-the-counter drugs. The distribution of serious adverse events were similar for both ethical-the-counter and over-the-counter drugs. Conclusion: Differences were observed in age, gender, reported medications, and symptoms for both ethical-the-counter and over-the-counter drugs. Further pharmacovigilance activities considering the adverse event characteristics of over-the-counter drugs, which are comparable to ethical-the-counter drugs, should be performed.

  • Objectives: The objective of this study is to evaluate weight change and analyze adverse events in overweight and obese women with polycystic ovary syndrome (PCOS) who were prescribed with Gamitaeeumjowee-tang. Methods: A retrospective chart review was conducted for medical records of patients with PCOS, who were administered with Gamitaeeumjowee-tang for a period of 12 weeks between January 2019 and December 2021. Outcomes were total weight loss/weight loss rate, the percentage of patients who lost more than 5% and 10% of their baseline weight. Adverse events (AEs) reported by patients were evaluated by severity, causality and system-organ classes. Results: A total of sixty-seven patients were included (mean±standard deviation, Age 28.78±5.25 years, weight 76.78±12.84 kg, body mass index 29.2±4.26 kg/m2). The average total weight loss in PCOS patients was 6.57±3.07 kg and the average weight loss rate was 8.55±3.65%. The percentage of patients with more than 5% and 10% weight loss compared to their baseline weight was 86.56% and 25.37% respectively. The analysis of adverse events are as follows: Causality assessment with World Health Organization-Uppsala Monitoring Centre of AEs showed 'Unlikely' was the most common (71.7%) and severity evaluations with Common Terminology Criteria for Adverse Events showed almost all symptoms were mild (98.9%). Conclusions: Gamitaeeumjowee-tang helps to lose weight of PCOS patients, which is overweight or obese, and no serious adverse events have occurred. Additional well-designed clinical studies are recommended.
