Objectives: The purpose of this study was to evaluate the quality of reporting for case reports published in Journal of Oriental Neuropsychiatry from year 2018 to 2021 compared with year 2013 to 2017 in order to recommend ways to improve the quality of case reports published in the future. Methods: To evaluate the quality of case reports identified by electronic searching in Oriental medicine Advanced Searching Integrated System (OASIS) and by hand searching from archives on peer review system of Journal of Oriental Neuropsychiatry using CAse REport (CARE) guideline. The researcher assessed the quality of reporting based on the CARE guideline as 'Sufficient', 'Not-Sufficient', 'Not-Applicable', and 'Not-Reported' for case reports published from 2018 to 2021 in Journal of Oriental Neuropsychiatry. In addition, it was compared with previous case reports published from 2013 to 2017. Results: Finally, 17 case reports were included for the assessment. General quality of reporting for case reports published from year 2018 to 2021 was improved compared with that of previous case reports published in 2018. The maximum value (46.4%→60.7%, 14.3% increase), the minimum value (22.2%→32.1%, 9.9% increase), and the median value (39.3%→50.0%, 10.7% increase) of the report rate evaluated as 'Sufficient' were generally improved. The maximum value (53.6%→50.0%, 3.6% decrease), minimum value (25.9%→21.4%, 4.5% decrease), and median value (35.7%→32.1%, 3.6% decrease) of the report rate evaluated as 'Not-Sufficient', the maximum value of the report rate evaluated as 'Not-reported' (40.7%→25.9%, 14.8% decrease), the minimum value (14.7%→10.7% decrease), and the intermediate value (14.7% decrease) were also generally improved. Four items (8b, 8d, 10c, and 13) were evaluated as 'Not-Reported'. These items seem to be items that need urgent improvement along with 8c, which showed a significant decrease in reporting rate. Conclusions: There are needs to improve the quality of case reports in Journal of Oriental Neuropsychiatry by comparing case reports published from year 2013 to 2017 with case reports published from year 2018 to 2021. To improve the quality of case reporting, sufficient education at the academic level should be provided on thesis preparation methods. It is also necessary to develop a tool for evaluating the quality of case reporting that reflects characteristics of Korean Medicine.

For 2007 Korea presidential election, most polls by telephone surveys indicated Lee Myung-Bak led the second runner-up Jung Dong-Young by certain margin. The margin between two candidates can be estimated accurately by averaging individual poll results, provided there exists no systematic bias in telephone surveys. Most Korean telephone surveys via telephone directory are based on quota samples, with the region, the gender and the age-band as quota variables. Thus the surveys may result in certain systematic bias due to unbalanced factors inherent in quota sampling. The aim of this study is to answer the following questions by the analytic methods adopted in Huh et al. (2004): Question 1. Wasn't there systematic bias in estimates of support rates. Question 2. If yes, what was the source of the bias? To answer the questions, we collected eighteen surveys administered during the election campaign period and applied the iterated proportional weighting (the rim weighting) to the last eleven surveys to obtain the balance in five factors - region, gender, age, occupation and education level. We found that the support rate of Lee Myung-Bak was over-estimated consistently by 1.4%P and that of Jung Dong-Young was underestimated by 0.6%P, resulting in the over-estimation of the margin by 2.0%P. By investigating the Lee Myung-Bak bias with logistic regression models, we conclude that it originated from the under-representation of less educated class and/or the over-representation of house wives in telephone samples.

Background: The disclosure of a diagnosis of cancer is complex, particularly in older patients. The aim of this study was to investigate the association between age and not knowing the diagnosis, and its impact on mood. Materials and Methods: The study included 70 patients with various types of solid and hematologic cancer in early stages, which were followed up in an outpatient oncology/hematology clinic in Turkey between January, 2014 and June, 2014. Initially the caregivers of patients were asked whether the patients knew their diagnosis or not. A questionnaire for the Geriatric Depression Scale was then administered to the patients. Patient age, gender, marital status and education level were noted and analyzed with respect to knowing the diagnosis and depression. Results: Of the 70 patients, 40% of them were female. The mean age was $68.2{\pm}8.9$. The rate of the patients who does not know their diagnosis was 37.1% (n=26). The overall depression rate with GDS was found 37.1% (n=26) among the participants. There was no association with knowing the diagnosis (p=0.208) although the association between not knowing the diagnosis and age was significant (p=0.01). Conclusions: In this study we revealed no association between not knowing the diagnosis and depression in elderly patients. Contrary to what some has thought, the patient is not protected from psychological distress by not being informed about the diagnosis. We believe this study and similar ones will help to discuss and further explore patient autonomy, the principle of respect to self-determination and end of life issues in different cultures.

This thesis assumes that the teaching objective of the Probability unit of the 8th grade textbook under the 7th National Curriculum is to enhance the ability to analyze and utilize informations. And we examine them if this point of view is fully reflected. Based on the analysis of the textbook analysis, followings are found. 1) It is necessary to emphasize more enumerating all possible cases and to induce formulae counting the number of possible cases through organizing them 2) The probability is to be decribed more clearly as a likelihood of events and to be introduced and followed through various students' experiences and the relative frequencies. Less emphasis on probability computations, while more emphasis on probability comparisons of events are recommended. 3) The term "influential events"(a kind of stochastic correlation) is ambiguous. It is necessary to make clear what it means at tile level of the 8th grade or to discard it for it is to be learned at the 10th grade again. Especially, contingency table has been introduced at the 9th grade under the 7th National Curriculum. 4) Uses of the likelihood principle in making a decision and in learning the reliability of it should be encouraged. And students are to team the hazard of transitive inferences in probability comparisons. As a consequence of above, we feel that textbook authors and related stakeholder are to be more serious about the behavioral changes of students that may come along with the didactics of specific contents of school mathematics.

The International Labor Organization (ILO) selected fishing as the most dangerous group of jobs in the world, and it is well known in Korea as a 4D industry. Offshore large purse seine accounts for the largest portion of the fishing industry in the coastal region with high death rate and the accident rate. The repeated disaster rate survey by the Korea Maritime Institute (KMI) shows offshore large purse seiner is the highest at 22.3 percent and coastal gill nets and offshore stow net are following at 12.4 percent and 11.9 percent in order. Therefore, risk factors occurring in offshore large purse seiners were analyzed based on data from the National Federation of Fisheries Cooperatives (NFFC) for three years from 2015 to 2017 and 4M (Man, Machine, Media, Management) 3E (Engineering, Education, Enforcement) techniques were used to provide a safe fishing environment. The number of accidents on offshore large purse seiners each year was more than 150, and the number of accidents on every fishing boats was as high as 17 percent in 2015. If the accident rate and the risk level were divided by insurance, the accident resulting from contact with machinery was the highest, and the risk of a contact with gear was low but frequently occurring. This was caused by collisions and contact with gear in situations where death and disappearance risk are not high, and accident types in situations where death and loss risk are considered to be contact with machinery, falls or other accidents. Through these analysis techniques, the frequency and risk of each type of accident on a offshore large purse seiners can be demonstrated, and it is expected to raise awareness of a safer fishing environment and contribute to the reduction of accidents.

We compared and analyzed the factors affecting the lecture evaluation of IT subjects, which are mandatory for all students of H University. The purpose of this study is to determine whether lecture satisfaction has a significant correlation with academic achievement, attendance rate, and categories of courses. In this study, we check whether the lecture satisfaction of IT liberal arts subjects that require a lot of computer-based practice differs from that of other liberal arts subjects. We used the 2,149 evaluation data of 12 lectures submitted by 2,322 students in the first and second semesters of year 2019 at University H. As for the lecture evaluation results, in addition to the evaluation scores of the multiple choice questions, the subjective questions were also quantified by classifying the statements submitted by the students into positive and negative types to make the results of the lecture evaluation objective. Our research results show that student group who have the higher attendance rates and academic achievements have higher level of lecture satisfaction and they also use more positive words than negative words in subjective evaluation questions. Students with the lower score use the more negative words, but the ratio between positive and negative words does not differ between groups. Higher attendance rates groups in the basic programming courses and software applications courses have higher lecture satisfaction ratio. But in the intermediate programming courses, the higher attendances rate and the lecture satisfaction do not have any significant relationship. Also students in the intermediate programming courses use more negative words than those in the basic programming courses.

The research was based on long-term studies on the major physico-chemical and hydrological factors and zooplankton community dynamics in the Hwang River. We had 341 times survey and collected zooplankton samples in the Hwang River of mid-Nakdong River from 1995 to 2013. We identified 97 zooplankton species, including 77 rotifers, 16 cladocerans, and 4 copepods. The total zooplankton abundance and species diversity were shown distinctive temporal variation (ANOVA, p<0.001). Annual average of zooplankton population density was 58.4±3.2 ind L^-1 (n=341) and the lowest was 17.0±3.8 ind L^-1 (1996, n=20), while the highest was 151.5±32.3 ind L^-1 (2010, n=22). For zooplankton, small rotifer groups(e.g., Keratella sp., Brachionus sp., Trichotria sp.) dominated the study site for 19 years survey. Statistical analysis revealed that there were positive relationships with SiO₂ (p=0.002) and water level (p<0.001) for the high abundance of rotifer community. There were considerable variations both the total cladocerans population and the number of cladocerans' species concerning annual precipitation. Despite the appearance of various zooplankton in the Hwang River, the mean population density remained low. Due to the lateral structures in the Nakdong River, the downstream basin of the Hwang River is inevitably affected. The zooplankton community in our study site is considered to be mainly influenced by external factors that can stably increase and maintain the volume of the water body and internal factors that induce an increase in food sources through the inflow of nutrients into the water body.

Occupational ethical awareness is a system of norms and standards of behavior and an important component of professionalism that affects organizational performance and commitment. The purpose of this study is to examine the mediating effect of professionalism on the relationship between job ethics and organizational commitment of civil servants. A survey was conducted on 300 central government officials with more than one year of employment. 261 copies were used for the final analysis. The results are as follows. First, the vocational ethics of civil servants had a significant effect on professionalism. The higher the years of service, the higher the level of ethics. Second, the work ethic of public officials had a significant effect on organizational commitment. These results can be interpreted as the internal commitment of civil servants to the state of work ethic. Third, the mediating effect of professionalism was verified in the relationship between public morality and organizational commitment. Based on these results, the public ethics of public servants are the basis for accepting public values and goals. Vocational expertise with embedded codes of conduct and value systems influences organizational commitment. As a practical implication for improving the ethical ethics of public officials, education programs for improving ethical consciousness according to job titles and duties were provided, and the ethical ethical competence was presented.

This study was performed to identify the importance and performance of hospice volunteer's activities perceived by hospice volunteers. Methods: The subjects were 259 hospice volunteers from six hospitals in Daegu and Gyeongsangbukdo areas. A list of hospice volunteer's activities was developed by authors, based on literature, and interviews with the hospice volunteers were used to measure the perception on the importance and performance of their activities. Data were analyzed by using Descriptive statistics, t-test, One-way ANOVA with Scheffe test, and Pearson's product-moment correlation in SPSS Win 12.0. Results: The average of the importance of hospice volunteer's activities was 3.09 and the performance was 2.31, which was lower than the importance. There was a significant correlation between the importance and the performance (r=.487, P=.000). There were significant differences in total score of the importance, depending on religion, education, and period of hospice volunteer activity of subjects. There were significant differences in total score of the performance, depending on age, religion, and period of hospice volunteer activity of subjects. Conclusion: The importance of hospice volunteer's activities, perceived by hospice volunteers, was relatively high, however their performance didn't reach the level of the importance. Some characteristics of the volunteers influenced the perception of the importance and performance of the hospice volunteer's activities. The findings of this study are expected to provide useful information for the development of educational and management programs the hospice volunteers.

In the TIMSS assessment goal and open TIMSS 2007, Singapore recorded a lower overall achievement level compared with Korea; however, the excellent results shown by Singapore furnished an opportunity for various countries to research into the education in Singapore. This paper conducted a comparative analysis of the "Proportion, Proportional Expression, and Percentile" area out of the three topics involving "Fractions and Decimals", "Proportion, Proportional expression, and Percentile", and "Measurement", in all of which Singapore exhibited a higher percentage of correct answers than Korea. The paper was able to discover the following differences through a comparative analysis of how Korean and Singaporean textbooks deal with the open questions of TIMSS 2007 after looking into them according to four assessment goals. First, the Singaporean textbook introduced the concept of proportion one year ahead of the Korean textbook. Second, the Singaporean textbook repeatedly coped with the topic of "Proportion, Proportional Expression, and Percentile" in depth and by academic year, and its volume was larger than that of the Korean textbook. Third, there was a difference in the introduction and definition of the concept of proportion. Fourth, the way of introducing a proportional expression was also different, and the Singaporean textbook proposed many more questions that utilize this expression in ordinary life. Based on these differences, the paper suggested implications that could be applied to the Korean curriculum and textbook.
