This study used an in-house beta version code, developed on the Microsoft® Excel platform and based on the Regulatory Guide 1.109 model, for radiation dose calculations. The results were compared with those of NRCDose3 Code Version 1.1.4. Although most results were compatible, five significant discrepancies were identified. First, potential errors in the effective dose for 3H inhalation and ingestion were due to inadequate incorporation of dose coefficients based on chemical forms or absorption types in the GASPAR module. Second, potential errors in 14C effective doses resulted from incorrect application of age-specific consumption values and dose coefficients. Third, potential errors for 131I inhalation doses occurred due to inadequate consideration of dose coefficients for chemical form or absorption type in the GASPAR. Fourth, potential errors in equivalent dose for radionuclides (e.g., 60Co and 131I) were caused by inconsistencies in the ordering of organs or tissues in dose coefficients and output files. Fifth, in the LADTAP module, when “Salt water” was selected and the International Commission on Radiological Protection Publication 72 was applied, liquid effluent doses were incorrectly output for only three age groups instead of six. This study analyzes these errors and proposes interim corrective measures to ensure accuracy pending software revisions.

According to the ROK-IAEA Comprehensive Safeguards Agreement (CSA), the ROK submits inventory change reports (ICRs), physical inventory lists (PILs), and material balance reports (MBRs). Suppose inventory changes occur in each material balance area (MBA). In that case, the facility operators prepare ICRs monthly, conduct physical inventory taking (PIT) every 12 to 18 months, and submit PILs and MBRs to KINAC. KINAC reviews ICR presented by the facility operators, submits it to the IAEA, and reports it to the Nuclear Safety and Security Commission (NSSC). Various methods have been prepared and implemented to minimize errors in reviewing the accounting reports submitted by the facility operators. Accordingly, this paper analyzes the mistakes in the accounting reports that occurred over the past two years and proposed methods to improve them. The basis for carrying out the accounting reports is stipulated mainly in the CSA and the Nuclear Safety Act. First, Article 63 of the CSA describes the rationale for submitting the accounting reports, and the details are described in detail in the subsidiary arrangement. Article 98 of the Nuclear Safety Act stipulates information related to accounting reports, and details are described in the regulations on reporting internationally regulated materials, etc., of the NSSC Notice No. 2017-84. Among the accounting reports submitted in 2021, a total of 36 errors were confirmed. There were ten errors related to inventory changes, followed by six errors in the material balance period (MBP) in the header information. There were four cases of spacing, weight mismatch, and overdue errors, and the rest were related to grammar errors. There were a total of 30 errors in the accounting reports identified in 2022. MBP errors of header information, which occurred the second most in 2021, was the highest with nine, followed by six inventory change errors and five weight mismatch and overdue errors, respectively. Compared to 2021, the total number of errors has decreased by about six, which is interpreted as the result of outreach activities through accounting reporting workshops and nuclear control education conducted by KINAC. Accounting reporting is the most critical part of the Nuclear Material Accounting and Control (NMAC) system. Efforts to check errors in accounting reports and improve report quality through outreach activities could be confirmed by the statistics of the two years analyzed earlier. In the future, if the reporting program used by the facility operators is improved to minimize errors and manage the accounting reporting system through continuous maintenance work, the quality of the accounting reports will be upgraded to the next level.

이 연구는 Skype를 활용하여 일본인 고급 학습자의 구어 오류 양상을 분석하고 교육적 의의를 제시하는 것을 목적으로 한다. 학습자 발 화 2,947어절을 대상으로 오류 양상을 분석하였다. 그 결과 문법 오류가 34건으로 가장 많았으며 어휘(26건), 발음(22건), 담화(4건) 오류 순으로 나타났다. 이로써 알 수 있는 것은 첫째, 고급 학습자임에도 불구하고 모국 어 간섭의 영향을 여전히 받고 있다는 점. 둘째, 어휘 오류에서는 학습 어휘량이 많아지면서 유사 어휘에 의한 오류가 많이 나타난 점. 셋째, 두 언어의 문법 체계가 비슷하다고는 하지만 그럼에도 문법 오류가 가장 많이 발생했다는 점이다. 향후 일본인 학습자를 대상으로 교수를 할 때 이런한 점을 고려하여 이루어져야할 것이다.

The knowledge of spelling cannot be earned by learning the relations between the sounds and graphemes. However, this study shows that the learners' knowledge is not a mere result of simple memorization. The current study found that the learners’ spelling knowledge is interwoven with their established phonemic inventory and their imperfect knowledge of the target language spelling. Using a learner corpus (KNU English Learner Corpus) constructed from young learners, primary school grades from 4 to 6, enrolled in a gifted English program, we extracted and examined 125 erroneously spelled words each from the basic level and the advanced level subcorpus. Building on Justicia et al. (1999), the error data were classified into six categories and an additional category of morpheme error (MOR) with substitution and omission errors accounting for 76.3% of the total errors. Conducting further analysis, we were able to identify typical cases of the errors and the underlying causes inducing the errors. Generally speaking, the substitution error is found to be due to the variability between grapheme and sound whereas the omission error is often caused by the learners’ tendency to prefer simpler graphemephoneme relations. There also exists considerable intervention of the learners' Korean phonemic inventory, particularly in lower level learners. The findings from this study can be used to provide various specific guides for effective spelling instruction and help learners become more confident about their writing.

Purpose: This study investigated the effects of valuation errors on the capital market through the earnings forecasting errors of financial analysts. As a follow-up to Jensen (2005)'s study, which argued of agency cost of overvaluation, it was intended to analyze the effect of valuation errors on the earnings forecasting behavior of financial analysts. We hypothesized that if the manager tried to explain to the market that their firms are overvalued, the analysts’ earnings forecasting errors would decrease. Research design, data and methodology: To this end, the analysis period was set from 2011 to 2018 of KOSPI and KOSDAQ-listed markets. For overvaluation, the study methodology of Rhodes-Kropf, Robinson, and Viswanathan (2005) was measured. The earnings forecasting errors of the financial analyst was measured by the accuracy and bias. Results: Empirical analysis shows that the accuracy and bias of analysts' forecasting errors decrease as overvaluation increase. Second, the negative relationship showed no difference, depending on the size of the auditor. Third, the results have not changed sensitively according to the listed market. Conclusions: Our results indicated that the valuation error lowered the financial analyst earnings forecasting errors. Considering that the greater overvaluation, the higher the compensation and reputation of the manager, it can be interpreted that an active explanation of the market can promote the accuracy of the financial analyst's earnings forecasts. This study has the following contributions when compared to prior research. First, the impact of valuation errors on the capital market was analyzed for the domestic capital market. Second, while there has been no research between valuation error and earnings forecasting by financial analysts, the results of the study suggested that valuation errors reduce financial analyst's earnings forecasting errors. Third, valuation error induced lower the earnings forecasting error of the financial analyst. The greater the valuation error, the greater the management's effort to explain the market more actively. Considering that the greater the error in valuation, the higher the compensation and reputation of the manager, it can be interpreted that an active explanation of the market can promote the accuracy of the financial analyst's earnings forecasts.

The paper aims to investigate the performance of domestic Saudi Arabian ETFs. ETFs are investment vehicles in vogue. These instruments were the first levers for investors allowing them to enter some markets that have been highly protected or out of reach. Saudi Arabia, which has been promoted as an emerging country by MSCI, seeks to attract more foreign investors. The first ETFs were launched in the years 2010-2011. Even though their number has not increased since then, there is a desire to attract a large number of investors. We use premiums/discounts analysis, standard risk-return models, and tracking errors measurements to assess how closely their replicate the underlying benchmark based on monthly data. The results indicate that out of the three funds investigated two are slightly traded at premium, while the latter exhibit a price discount. However, tracking errors are at minimum for all funds suggesting that they track well the benchmark index. Further, the Jensen’s model shows that alphas are negative or null, and betas capture largely the systematic risk which is consistent with index investing strategies. Finally, traditional risk-adjusted measures of performance are used to compare ETFs, and results exhibit negative ratios showing that portfolios achieve lower return than the risk-free rate.

Recently, because of the increased needs for isolation device structure, a lot of buildings equipped with isolation systems are designed. In this paper, we provide the information about the seismic isolation effects due to the stiffness variation of isolation devices due to the manufacturing errors for middle layer seismic isolation.

Formal Safety Assessment (FSA) has been mostly implemented on the hardware aspects of vessels. Although there are guidelines regarding human error FSAs, there have not been many assessments in such areas. To this end, this study seeks to use precedent studies for the safe operation of DP vessels, conducting an FSA regarding human error of DP LOP (Loss of Position) incidents. For this, the study referred to precedent studies for the frequency of DP LOP incidents caused by human errors, adding the severity of LOP incidents, and then applying them to the Bayesian network. As a result, the study was able to confirm that among DP LOP incidents caused by human errors, the drive-off from skill-based errors was 74.3% and the drive-off from unsafe supervision was 50.5%. Based on such results, RCOs (Risk Control Options) were devised through a brainstorming session with experts coming up with proposals including providing mandatory DPO training, installing DP simulator on the vessels, drawing up measures to understanding the procedures for safe operation of DP vessels. Moreover, it was found that mandatory DPO training is reasonable in terms of cost benefits and that while installing a DP simulator is not suitable in terms of cost benefits, it can significantly reduce risks when operating DP vessels.

It is highly likely that Korean college students often commit inadvertant speech errors of replacing /t/ or /d/ with palatoalveolar /ʧ/ and /ʤ/ in the consonant clusters of /tr/ and /dr/. The writers presume that this is due to their confusion about the place of articulation of /t/ and /d/ with /ʧ/ and /ʤ/ /in /tr/ or /dr/ sequence, their lip-rounding difference from that of /ʧ/ and /ʤ/, and finally students’ inaccurate knowledge about the phonetic constraint of */ʧr/ and */ʤr/ in English syllable structure. Under such hypotheses this study analyzes the responses from an experiment group of fifteen Korean college students based on phonetic theories and probes into possible background reasons for this over-production as a form of speech errors.

This paper is to develop the position error equations including the attitude errors, the errors of nadir and ship's heading, and the errors of ship's position in the free-gyro positioning and directional system. In doing so, the determination of ship's position by two free gyro vectors was discussed and the algorithmic design of the free-gyro positioning and directional system was introduced briefly. Next, the errors of transformation matrices of the gyro and body frames, i.e. attitude errors, were examined and the attitude equations were also derived. The perturbations of the errors of the nadir angle including ship's heading were investigated in each stage from the sensor of rate of motion of the spin axis to the nadir angle obtained. Finally, the perturbation error equations of ship's position used the nadir angles were derived in the form of a linear error model and the concept of FDOP was also suggested by using covariance of position error.

본 연구는 한국어와 아랍어의 모음의 (구어체 표준아랍어인 이집트 방언을 대조군으로 설정했다.) 대조를 바탕으로 학습자의 모음오류 원인과 유형을 분석하였다. 21개의 모음을 가진 한국어와 10개의 모음만을 표준발음을 인정하는 구어체 아랍어는 완벽한 대응 쌍을 이루기 어려웠다. 이런 이유로 인한 오류는 다음과 같이 나타났다. 모음 발음 중 /ㅓ/, /ㅜ/, /ㅗ/를 발음 하는데 정확한 구분을 두지 못했으며 이중모음이 없는 구어체 표준아랍어(이집트 방언)의 특성상 이중모음을 2개의 단모음으로 연이어 발음하는 오류가 나타남을 알 수 있었다.

시드마이어에 의하면 게임은 일련의 흥미로운 선택들이라고 하였다. 이는 흥미로운 선택들이 게임을 재미있게 만드는 주요 요인이란 의미이다. 본 논문에서는 게임에서 존재하는 흥미롭지 않는 선택대안을 게임플레이의 전략적 오류라 정의하고 이들 오류를 검출하는 방법을 제안하였다. 제안하는 방법은 게임이론에서 게임을 표현할 때 사용하는 보수행렬들을 검사하여, 게임플레이의 전략적 오류를 검출하는 방법이다. 이 방법은, 게임의 보수행렬들만 검사하는 경우에는, 적절한 대응전략이 없는 선택, 절대 우위 선택, 절대 열등 선택, 그리고 비슷한 보상이 이루어지는 선택들의 오류들을 검출할 수 있다. 그리고 게임의 보수행렬들과 대응하는 사용빈도율들을 함께 사용하는 경우에는, 추가적으로, 기대 보수가 매우 낮은 선택, 기대 보수가 매우 높은 선택, 사용확률이 매우 낮은 선택 그리고 사용확률이 매우 높은 선택들의 오류들을 검출할 수 있다.
