N/A In this study, to gain the semi-solid alloy we employed the electromagnetic rotation by a induction motor of 3-phases and 2-poles for Al-7wt%Si alloy and observed the size of primary solid particle, distribution state of primary solid particle, the degree of sphericity, and fraction of primary solid for the evaluation of its results. The size of primary solid particle increases from 98㎛ to 118㎛ as solid fraction increases from 0.2 to 0.5. The degree of sphericity increased as the solid fraction increased. Solid particles obtained from the microstructures of isothermally held sample were coarsened and the degree of sphericity was enhanced as isothermal holding time increased. However, when the sample was stirred for more than 40min, solid particles merged together and liquid phase was entrapped within the cluster of solid particles. The size of primary solid particle was not changed significantly with the variation of input voltages by 160V over which solid particles began to merge together to be a large cluster of about 170㎛ at 180V. The standard deviation and the degree of sphericity were not changed significantly with the variation of input voltage.

N/A To gain a semi-solid alloy the electromagnetic stirring by an induction motor of 3 phase and 2-poles was used. And it was also observed that the change of primary particle size, distribution and degree of sphericity by addition of a refiner, Al5Ti1B. The effect of refiner on the distribution and dimensions of primary particles prior to that electromagnetic refining on those was examined. In case of electromagnetic stirring with the refiner Al5Ti1B, the average size of primary solid particles increased as the fraction of solid increased. However it decreased as the amount of Al5Ti1B addition increased to 0.5% and then it was increased again as the addition amount of Al5Ti1B increased above 1.0%. The average size of primary solid particles was 31㎛ in case of melt temperature 600℃ when the fraction of solid was 0.3, input voltage 140V, cooling rate 2.5℃/s, and 0.5% Al5Ti1B. To use the electromagnetic stirring with the addition of a refiner was able to obtain more small primary solid particles than to use the electromagnetic stirring only.

전자교반에 의한 Al 합금의 초정입자 미세화에 관한 연구

N/A The change of microstructure of Al-7wt%Si alloy was examined by using a induction motor of 3-phases and 2-poles in semi-solid electromagnectically stirring process. The size and degree of sphericity of primary solid particles were observed by means of change of cooling rate. At a certain cooling rate, the size of primary solid particles increased and the sphericity became perfect, as the fraction of solid increased. The average size of primary solid particles was 43㎛ when the fraction of solid was 0.3 and at 600℃, input voltage 140V, cooling rate 2.5℃/s. It was shown that the size of primary solid particles was proportional to local solidification time.

Clear ceil sarcoma(CCS) is an uncommon soft tissue sarcoma that occurs in tendons and aponeuroses, usually of the lower extremities and is believed to be of neural crest origin that have a capability to produce melanin. These tumors commonly metastasize and have a very poor prognosis. The fine needle aspiration cytologic finding of CCS is not well documented. We recently experienced a case of CCS. The patient was a 54-year-old male with painful swelling of the right inguinal area. Fine needle aspiration cytology revealed polygonal or fusiform tumor cells with clear or granular cytoplasm and vesicular nuclei containing one or two nucleoli. Immunohistochemical staining for S-100 protein and HMB-45 revealed strong positivity and variable developing stages of premelanosomes were observed by electron microscopy in the excised specimen.

우리나라가 체결한 FTA에서의 무역원활화 규정에 관한 고찰: 상품무역을 중심으로

임성철(Sung-Chul Lim) 한국무역연구원 2016 무역연구 Vol.12 No.5

Trade facilitation refers to all measures which expand international trade by increasing efficiency and reducing transaction costs by simplification or elimination of unnecessary and complicated procedures, practices, and associated infrastructure. This paper examines insufficient points of provisions of Trade Facilitation in FTAs concluded by Korea when compared to the provisions of trade facilitations defined by international organizations or FTAs of other countries. Currently, South Korea has FTAs with 15 countries already in force. Among the provisions in 11 of these FTAs is chapter on trade facilitation. A Korea FTA does not regulate measures of trade facilitation such as prohibition of consular transaction requirements, optional electronic payment, separation of release from final determination of customs duty, taxes, fees and charges, establishment and publication of average release times, movement of goods intended for import under customs control, prohibition of mandatory use of customs brokers, common border procedures and uniform documentation requirements, return of the rejected goods, temporary admission of goods and inward and outward processing, perishable goods, single window and freedom of transit. In future FTA negotiations it is suggested that it is necessary to negotiate the above-mentioned trade facilitation measures which have not yet been discussed.

So far several attempts have been made to digitalizing sea transport documents. Three notable examples are SeaDocs, Bolero, e-B/L Korea and Ess-Databridge. Ess-Databridge was established in 2003, with the aim of promoting the use of electronic alternative to shipping documents. The ESS-Databridge system was piloted from 2005 and went live in January 2010. The ESS-Databridge operates under a private legal outline, the Databridge Services and Users Agreement (DSUA). In the Ess-Databridge system, only the user who is in control of the original bill of lading will be able to indorse it on to another user. Once the indorsement is effected and unless the indorsee decide store turn the documents, the indorser loses control and retains access only to an electronic document marked 'copy' for its records. A feature that appears to have been crucial to the success of the CargoDocs service is that visually, e-B/Ls produced using ESS-Databridge appear identical to the paper documents. The ESS-Databridge may be even more successful if the legislators take certain steps that will increase uniformity and certainty in electronic transport documentation.

임성철 ( Sung Chul Lim ),정문진 ( Moon Jin Jeong ),김세은 ( Se Eun Kim ),김승현 ( Seung Hyun Kim ),김삼철 ( Sam Cheol Kim ),서승용 ( Seung Yong Seo ),김탁 ( Tak Kim ),강성수 ( Seong Soo Kang ),배춘식 ( Chun Sik Bae ) 대한산부인과학회 2011 Obstetrics & Gynecology Science Vol.54 No.6

목적: 다낭성난소증후군(polycystic ovary syndrome, PCOS)을 estradiol valerate (EV)와 letrozole (LE)로 유발할 수 있는데 인간의 다낭성난소증후군과 가장 유사한 질환동물 모델이 무엇인가를 알아보고자 하였다. 연구방법: EV와 LE를 각각 랫드에 처리하여 PCOS를 유발시킨 후 희생시켜 난소를 적출하였다. 난소를 조직학적으로 관찰하여 다낭성 난소 변화 유발유무, 난소의 크기, 난포낭의 크기 및 수를 측정하고 난포 및 간질세포의 황체화 등을 비교 관찰하였다. 결과: LE처리군은 EV처리군에 비하여 난소의 크기 및 난포낭의 수가 유의하게 증가하고 난포막세포의 황체화가 뚜렷하여 인간의 PCOS와 더유사한 소견을 보였다. 결론: 랫드에서 LE처리에 의한 PCOS는 PCOS질환유발 동물 모델로 더 적합한 것으로 평가된다. Objective: To compare ovarian morphology of the estradiol valerate (EV)-and the letrozole (LE)-induced polycystic ovary syndrome (PCOS) in rat models. Methods: EV were injected (IM) to 10 Sprague-Dawley rats and LE were administered (PO) to the other 10 Sprague-Dawley rats for 21 days. Sixty days after single injection of EV and 21 days after LE administration, the animals were sacrifi ced and the ovaries were sectioned, measured and analyzed histopathologically. Results: LE-treated group showed larger ovary bearing more abundant cystic follicles with luteinized theca cells. These fi ndings were more similar to human PCOS ovarian morphology. Conclusion: LE-induced PCOS model is recommended to conduct PCOS-related animal experiments.

UNCITRAL 전자양도성기록 모델법의 전자선하증권 적용에 관한 소고

임성철(Sung-Chul LIM) 한국무역상무학회 2018 貿易商務硏究 Vol.79 No.-

A primary reason that e-trade has not been prevalent is because there is no international consensus on how to recognize the electrical transfer of bill of lading. UNCITRAL enacted the Model Law on Electronic Transferable Records to promote the international transfer of electronic document or instrument such as electronic bill of lading and to ensure legal stability. The model law was enacted based on the principle of non-interference the substantive law, technological neutrality, and functional equivalence. The model law introduced the concept of ‘control’ in order to prevent the unauthorized duplication of electronic transferable records in electronic environments as infinite replication is possible and to apply the concept of possession, which is equivalent to paper-based transferable document or instrument or the factual dominance of transferable document or instrument, into electronic environments. The analysis of the possibility of collision between the electronic bill of lading of Bolero, essDOCS, e-B/L KOREA and the model law suggested that the majority of the model law did not conflict with or contradict the currently commercialized electronic bill of lading service. This is because the lawreferred to the existing electronic bill of lading in process and observed the technology-neutral principle during enactment. Replacement of a transferable document or instrument with an electronic transferable record needs to be improved for the exiting electronic bill of lading service. The model law is significant in that it not only gained international attention for the transfer of electronic bill of lading, but also has become the benchmark for enacting legislations on electronic document or instrument in each country. However, the model law is limited to a simple recommendation as we have seen from cases about UNCITRAL Model Law on Electronic Commerce and Model Law on Electronic Signatures. In order for electronic bill of lading to be as internationally prevalent as the paper ones, there needs the convention, something that goes beyond the model law. The prevalence of electronic bill of lading would be quicken if organizations that are influential in international trade such as UNCITRAL, International Maritime Organization (IMO), World Customs Organization (WCO), International Chamber of Commerce (ICC) should take initiatives towards the convention or agreement. An alternative could be mutually recognizing the use of electronic bill of lading among the FTA countries by adding the relevant clauses in their agreements.
