Manufacturing information systems including ERP, MES, PLM, SCM, and Control System are highly are interconnected horizontally and vertically among them. So it is imperative that those systems keep and share the common/related data in the appropriate way. The various types of BOMs are the most important data sets for designing, developing and producing product in recent manufacturing environment. In particular, the discrepancy and inconsistency between EBOM and MBOM information would worse a production and customer service level, and lower a productivity in R&D. In this paper, the data issues about transforming from EBOM to MBOM are presented. And then, we propose the methods for preserving the BOM information consistently. Finally, we implement the prototype by using SOA to show the possibility for developing a real system.

내암의 하학전통 계승과 정치사상의 특징

송치욱 ( Song Chi-wook ) 남명학연구원 2019 南冥學硏究論叢 Vol.24 No.-

이 논문의 목적은 남명이 강조한 ‘하학’이 유학의 본령을 담고 있는 전통이며, 이러한 남명의 하학 전통을 내암의 정치사상에 어떻게 이어지고 있는지를 밝히는 것이다. 내암은 남명의 고제高弟로서 ‘하학下學’을 강조하는 남명의 학풍을 계승하였다. 남명은 퇴계와 갈등하면서까지 하학을 강조하고, 하학을 실천하지도 못하면서 천리天理를 입에 담는다며 당대의 학자들을 비판했다. 남명에게 있어 하학은 상달의 공부를 위한 단순한 입문적인 것이 아니었으며, 오히려 유학의 본령을 담고있는, 떠나서는 안되는 것이었다. 송유宋儒는 물론이고 내암 또한 지적하듯 ‘하학’은 불교나 노장으로부터 유학을 구별하게 하는 주요한 정체성을 담고 있는 것이다. 이 글에서는 이러한 유학에서 하학이 차지하고 있는 중요성을 강조하고, 이러한 하학을 강조한 남명의 사상은 내암으로 이어져, 그의 출처관, 시대인식에 영향을 미쳤다는 점을 밝히고자 하였다. 내암은 스승인 남명의 행장을 찬술하면서 ‘하학’을 강조하는 모습을 강조하고 있으며, 남명의 출처에 대한 퇴계의 비판에도 ‘하학’의 기준에서 반박하고 변호하였다. 그리고 현실을 강조하는 하학을 기반으로 당대의 주요한 문제를 ‘허위虛僞’라 인식하고, ‘실實’을 통해 극복하고자 하였다. 그의 ‘실實의 정치사상’은 시의時宜와 현장성, 직접성, 적실성을 추구하는 것이었으며, 고원한 것보다는 비근한 것을 추구하며, 일상에서의 실천을 강조하는 하학의 전통이 기반된 것이었다. 그리고 이는 유학의 민본사상과도 이어지는 것이었으며, 내암에겐 보민保民사상으로 나타나고 있다. The purpose of this paper is clarify that the ‘Ha-hak’ emphasized by Nam-Myeong was the tradition containing the main principle of Confucianism, and how the Ha-Hak tradition was connected to Nae-Am’s political thought. As an eminent disciple, Nae-Am succeeded to Nam-Myeong’s academic tradition of emphasizing 'Ha-hak'. Nam-Myeong emphasized ‘Ha-hak’ even when he was at odds with Toe-Gye, and criticized scholars of the day, who talked Natural Law(天理) but did not practice Ha-hak. For Nam-Myeong, ‘Ha-hak’ was not a simple introductory course for the study of Shang-dal(上達), but it should not be left with the main purpose of Confucianism. As both Confucian scholar of Song Dynasty(宋儒) and Nae-Am stated, ‘Ha-hak’ contains a major identity that distinguishes Confucianism from Buddhism and Taoism. In this article, I intended to emphasize the importance of the 'Ha-hak’ study in the Confucianism and to clarify that Nam-Myeong’s ideology emphasizing Ha-hak succeeded to Nae-Am, and effected his view of Chulcheo(出處, working for state or living in seclusion) and awareness of time accordingly. Nae-Am stressed the point of the emphasis on "Ha-hak", while praising the master of the teacher, Nam-Myeong. Despite of Toegye's criticism about Nam-Myeong’s Chulcheo(出處), he refuted and defended it under the Ha-hak standard. Based on Ha-hak that emphasizes the reality, he recognized the main problem of the time as ‘falsehood(虛僞)' and tried to overcome it through Practicality(實)'. His practical political thought was to pursue appropriate time(時宜), realism, directness and appropriateness, and it was based on the tradition of Ha-hak, which emphasized the daily practice, pursuing something rather than a lofty one. This was followed by ‘People-oriented thought(民本思想)’ of Confucianism. For Nae-Am, it was eventually developed into ‘Thought for the people(保民思想)’.

아칼라지아 치료에서 풍선확장술과 보툴리늄 독소 주사요법의 비교연구

N/A Background/Aims: Preliminary studies have suggested that intrasphincteric injection of the lower esophageal sphincter(LES) with botulinum toxin(BoTx) is a safe and effective alternative to pneumatic balloon dilation(BD) in the treatment of achalasia. We have compared the efficacy between BoTx and BD in an ongoing prospective study. Methods: In a randomized trial, 16 patients with achalasia received either intrasphincteric injection of BoTx(100 units) or BD(Rigiflex 3.0 cm in diameter). Among 8 patients treated with BoTx, 3 to them had been treated unsuccessfu]- ly beforehand with BD. After one month and after three months, Treatment responses were assessed on the basis of changes in the symptom scores and parameters of esophageal manometric study. Results: Both BoTx without prior BD(n=5) and BD group(n=8) showed a decreased symptom score, LES pressure and gastroesophageal pressure gradient(GEPG) at 1 month also decreased. LES pressure at 3 months increased in the BoTx group. No patient treated within the BD group failed at 3 months, but 1(20%)patient in the BoTx without previous BD did fail. The failed BoTx group with prior BD didnt show a decreased symptom score. LES pressure and GEPG also didnt decrease and 2(66.7%) patients failed at 3 months after treatment. No significant complications were seen in both the BoTx and the BD group. Conclusions: Both BoTx injection and BD were effective treatments for achalasia. BD may provide a more effective long term treatment, as compared to BoTx, for achalasia. However BoTx injection in patients who failed prior BD showed a poor response and a high failure rate. Long term evaluation of safety and efficacy will be required to fully understand the utility of BoTx injection vs BD for achalasia. (Korean J Gastroenterol 1997;29:423-429)

Purpose It is a major goal to improve the product yields during production operations in the manufacturing industry. Therefore, factory is trying to keep the good quality materials and proper production resources, also find the proper condition of facilities and manufacturing environment for yields improvement. Design/methodology/approach We propose the hybrid framework to analyze to dataset extracted from MES. Those data is about the alarm information generated from equipment, both measurement and equipment process value from production and cycle/pitch time measured from production data these covered products during production. We adapt a data warehousing techniques for organizing dataset, a logistic regression for finding out the significant factors, and a association analysis for drawing the rules which affect the product yields. And then we validate the framework by applying the real data generated from the discrete process in secondary cell battery manufacturing. Findings This paper deals with challenges to apply the full potential of modeling and simulation within CPPS(Cyber-Physical Production System) and Smart Factory implementation. The framework is being applied in one of the most advanced and complex industrial sectors like semiconductor, display, and automotive industry.

N/A Background/Aims: Recently the esophagus is considered a major source of recurrent noncardiac chest pain to patients in whom exercise stress test and/or cardiac catheterization have excluded a cardiac etiology. To investigate the esophageal origin of noncardiac chest pain, esophageal motility tests including manometry, provocation test, and radioisotope esophahgeal transit study(RETS) were studied in patients with noncardiac chest pain. Methods: A total of l26 patients with noncardiac chest pain were assessed;they included 41 patients with normal coronary angiogram and 85 patients with normal noninvasive cardiac tests such as echocardiogram and exercise stress test done in Korea University Hospital from Feb. l993 to Aug. 1994. Results: 56 out of 126 patients(44.4%) with noncardiac chest pain had abnormal manometric findings which included 20(35.7%) nonspecific esophageal motility disorder, 17(30.4%) hypertensive lower esophageal sphincter, 9(16.1%) hypo- tensive lower esophageal sphincter, and 2(3.6%) nutcracker esophagus. Thirty eight out of 126(30.1 %) patients had abnormal manometric findings but no reproducible chest pain by provocation test and were considered to have a probable esophageal chest pain. When patients having positives for both provocation tests are counted as a single positive, 39 out of l26(3l /o) patients had their chest pain reproduced and were considered to have a defini(e esophageal chest pain. The combination of patients with definite esophageal chest pain(31%) and probable(30.17c) gave an overall diagnostic yield of 61.1% for our esophageal laboratory. There was no significant difference between invasive cardiac test group and noninvasive cardiac test group in the results of esophageal motility tests. RETS merely reflected the peristaltic abnonnalities with no more informations for esophageal chest pain. Conclusions: These results reveal that esophagus is considered a source of noncardiac chest pain in 61.1%. Provocation test complements esophageal manometry alone and increases diagnostic yield. RETS can be used in diagnosis of noncardiac chest pain accompanied by peristaltic abnormality of the esophagus. (Korean J Gastroenterol 1995;27:381-387)

N/A Objectives: Although esophageal manometry is widely used in clinical practice, there are little reliable reports concerning the normal values for esophageal manometry in Korea. Methods: 70 healthy volunteers (mean age: 42 years; range 18~68 years) were studided with a low compliance infusion system and ESR3 HR catheter. All subjects were given more than 10 wet swallows (5 cc Water). Results: 1) Mean LES pressure measured by RPT is 28.5±5.1 mmHg. Mean LES pressure measured by SPT is 24.1± 7.5 mmHg at midrespiration. Age had no effect on LES pressures whereas female subjects showed higher LES pressure (RPT) than male (p<0.05). 2) Mean amplitude and duration of peristaltic contractions in proximal esophagus were 62.4±21.6 mmHg, 2.8+-0.6 sec and in distal esopahgus 92.4±32.6 mmHg, 3. 2±0.8 sec, respectively. The prevalence of peristalsis, velocity of peristalsis, number of abnormal contractions were 98.5±5.2%, 3.5±0.9cm/sec, 0.0±0.1 respectively. Age and sex had no effect on amplitude, duration, velocity of peristaltic contractions. Conclusions: Our study of 70 healthy Koreans, ranging in age from 18 to 68 years, should help to establish standards for normal manometric findings and provide a guide line for the diagnosis of esophageal motility disorders.

N/A Background/Aims: Pneumatic balloon dilation(BD) is considered to be the first line of treatment in patients with achalasia. However there have been little reports about whether the parameters of esophageal manometry and scintigraphy predict the long-term results after BD. The aims of this study were to determine the relationship between changes in symptom improvetnent and esophageal motor function in response to BD. Methods: 21 patients with primary achalasia treated by BD were included. We used a balloon dilator(Rigiflex, 3.0 cm in diameter) and dilated twice for 1 minute each at a pressure of 7-15 psi, at a 5 minute interval. A comprehensive assessment of their symptoms and esophageal manometry and scintigraphy was performed before, 1 month after wards and again 1 year after BD. Results: 1) One year after BD, four people had recurrence of symptoms and the remaining 17 patients(81%) had been successfully treated. 2) There was no relationship between patients age, sex, duration of symptoms and the symptom improvement scores of a year later. 3) Significant correlation was detected between changes in the symptom score of a year later and parameters of esophageal motor function such as reduction of lower esophageal sphincter pressure, normalized reversed gastroesophageal pressure gradient, and different configuration of simultaneous contractions after BD. Conclusions: We conclude that the changes in objective responses such as lower esophageal sphincter pressure, gastroesophageal pressure gradient and configuration of simultaneous contractions are reliable predictors of symptom irnprovernent and recurrence in patients with achalasia treated by BD.
