The International Electrotechnical Commission(IEC) 61000-4-15 is a standard proposing techniques for a flicker meter test and measurement method. The IEC61000-4-15 ed1 announced in 1997 was not include tests for accurate verification. Also it was not explained flicker meter algorithm that can be directly applied to the other power systems. But the new edition of IEC61000-4-15 ed2 prescribes a variety of tests for verify flicker meter algorithm and it explains 'correction factor' used for measuring flicker in other power systems. It can measure flicker severity in 220V system by multiplying correction factor to the measured values with the 230V algorithm. This paper compared the method of measuring flicker severity in korea power system using the correction factor and the modified weighting filter, after verifying of digital flicker meter algorithm created by using matlab based on IEC61000-4-15 ed2.

DDC, LCC, and CC can be said as the major schemes for mordern general library classification. Among these, DDC, since its publication in 1876, has been continuously studies and revised by many scholars and practitioners to publish 20th edition in 1989: LCC also has been studied and revised by the specialists in each subject, since 1904; and CC(first edition 1933) is now on the stage of 7th edition(1987). Even though studied, revised and developed by many classificationists, all these schemes maintain the general framework of the beginning, only with the partial revision and expansion to reflect the developments of the subjects. and antioipated tremendous amount of works resulted from reclassification also can be a reason that disturbs the full innovative revision of the scheme, because these are used in many libraries as a basic tools for the classification. But all these schemes mainly based on the state of the discipline at the time of their creation, the beginning of 20the century, and so in some aspect it is natural for them to have many problems. This study aims to investigate the problems in these major schemes, to find some ways to solve the problems, and to suggest the ideas for the basic design of a new modern library classification scheme. This plan is prepared to be applied to the situation of all countries equally without any revision. And in its notation, it uses two digits of Arabic numerals as centesimal, and so it is named provisionally to Plan for Centesimal Classification (PCC).

The popular edition of "Hwangjenaegyeong somun(黄帝内經 素問)" was established by Wangbing(王冰)'s revising and annexing notes in the Dang(唐) Period. He revised "Jeonwongibon(全元起本)" which became the edition we currently know widely. To know how "Somun(素問)" had been handed down from the Su(隋) Period to the Dang(唐) Period before the establishment of Wangbing(王冰) 's edition, we reviewed the citation of "Somun" in the four books: "Ohaengdaeui(五行大義)", "Jebyeongwonhuron(諸病源候論)", "Sagijeong-ui(史記正義)", and "Oedaebiyobang(外臺秘要方)". As a result, it has been discovered that even if the reference was written as "Hwangjesomun(黄帝素問)" or "Somun(素問)", they did not correspond with the currently established "Somun(素問)" in many cases. On the other hand, there were identical sentences to the current "Somun(素問)" among the cited parts; whereas "Yeolron(熱論)" and "Jahakron(刺瘧論)" were often cited in the medical books such as "Jebyeongwonhuron(諸病源候論)" and "Oedaebiyobang(外臺秘要方)", "Yeolron(熱論)" and "Jahakron(刺瘧論)" were often cited. Thus, we can suggest that the relevant content of "Somun(素問)" should be considered important in the period in question and further that the concept of disease symptom might have changed in those days.

이 논문은 조선조 활자본계의 묘법연화경 판본에 관한 연구를 위해 묘법연화경의 동전과 유통 활자본계의 묘법연화경 판본의 유통, 각 판본들의 서지적 성격을 고찰하였다. 묘법연화경은 유통본의 종류가 많아서 그 계열을 가름하여 그 가치를 제고하는 것은 중요하다. 활자본은 초주갑인자본과 을해자본으로 세종.세조조에 찍어 유통시켰고 이들의 번각 본이 성종부터 영조조까지 유통되었다. 이들 판본에 나타나는 서지적인 성격은 사찰, 서체, 변상도, 경판간행질에 있어 다양하고 독특한 내용을 담고 있다.

Objectives: This study aimed to compare the utility of the Psychoeducational Profile-Revised (PEP-R), Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (K-WPPSI-IV), and Vineland Adaptive Behavior Scale, Second Edition (VABS-II) for evaluating developmental disabilities (DD) in preschool children. Additionally, we examined the correlations between the PEP-R, K-WPPSI-IV, and VABS-II. Methods: A total of 164 children aged 37-84 months were assessed. Children's development was evaluated using the PEP-R, K-WPPSI-IV, VABS-II, Preschool Receptive-Expressive Language Scale, and Korean Childhood Autism Rating Scale, Second Edition. Results: Of the 164 children, 103 had typical development (TD) and 61 had DD. The mean of the PEP-R Developmental Quotient (DQ), K-WPPSI-IV Full-Scale Intelligence Quotient (FSIQ), and VABS-II Adaptive Behavior Composite (ABC) scores were significantly higher in the TD group than in the DD group (p<0.001). The estimated area under the curve of the PEP-R DQ, K-WPPSI-IV FSIQ, and VABS-II ABC scores was 0.953 (95% confidence interval [CI]=0.915-0.992), 0.955 (95% CI=0.914-0.996), and 0.961 (95% CI=0.932-0.991), respectively, which did not indicate a statistically significant difference. The PEP-R DQ scores were positively correlated with the K-WPPSI-IV FSIQ (r=0.90, p<0.001) and VABS-II ABC scores (r=0.84, p<0.001). A strong correlation was observed between the K-WPPSI-IV FSIQ and VABS-II ABC scores (r=0.89, p<0.001). Conclusion: This study found that the PEP-R, K-WPPSI-IV, and VABS-II effectively distinguished DD from TD in preschool children, and no significant differences in utility were observed between them.

Stomach cancer is the fifth most common malignancy in the world. The incidence of stomach cancer is declining worldwide, however, gastric cancer still remains the third most common cause of cancer death. The tumor, node, and metastasis (TNM) staging system has been frequently used as a method for cancer staging system and the most important reference in cancer treatment. In 2016, the classification of gastric cancer TNM staging was revised in the 8^th American Joint Committee on Cancer (AJCC) edition. There are several modifications in stomach cancer staging in this edition compared to the 7^th edition. First, the anatomical boundary between esophagus and stomach has been revised, therefore the definition of stomach cancer and esophageal cancer has refined. Second, N3 is separated into N3a and N3b in pathological classification. Patients with N3a and N3b revealed distinct prognosis in stomach cancer, and these results brought changes in pathological staging. Several large retrospective studies were conducted to compare staging between the 7^th and 8^th AJCC editions including prognostic value, stage grouping homogeneity, discriminatory ability, and monotonicity of gradients globally. The main objective of this review is to evaluate the clinical and pathological implications of AJCC 8^th staging classification in the stomach cancer.
