Objectives : The purpose of our study was to discuss about the scholarship value and contents of the transcription of Correction of the Classic of Materia Medica that was obtained recently. Methods : We analysed the transcription of Correction of the Classic of Materia Medica itself and compared form and matter with Shennong's Classic of Materia Medica[神農本草經], Compendium of Materia Medica[本草綱目]. Results : 1. It is obvious that the transcription of Correction of the Classic of Materia Medica is one of the book works of Lee Gyujun. 2. The transcription of Correction of the Classic of Materia Medica was written to recover the original figure of Shennong's Classic of Materia Medica standing on Compendium of Materia Medica. Lee Gyujun corrected qi, flavor and main effects of herbs according to his medical sight, and classified herbs into three grade. Conclusions : The transcription of Correction of the Classic of Materia Medica is not an original book but an interim book on working process. But it reflects the medical sight of Lee Gyujun and the medical level of those days sufficiently. Also it is the only study of Shennong's Classic of Materia Medica in Chosun dynasty.

MIFARE Classic is the most popular contactless smart card, which is primarily used in the management of access control and public transport payment systems. It has several security features such as the proprietary stream cipher Crypto 1, a challenge-response mutual authentication protocol, and a random number generator. Unfortunately, multiple studies have reported structural flaws in its security features. Furthermore, various attack methods that target genuine MIFARE Classic cards or readers have been proposed to crack the card. From a practical perspective, these attacks can be partitioned according to the attacker's ability. However, this measure is insufficient to determine the optimal attack flow due to the refined random number generator. Most card-only attack methods assume a predicted or fixed random number, whereas several commercial cards use unpredictable and unfixable random numbers. In this paper, we propose optimal MIFARE Classic attack procedures with regards to the type of random number generator, as well as an adversary's ability. In addition, we show actual attack results from our portable experimental setup, which is comprised of a commercially developed attack device, a smartphone, and our own application retrieving secret data and sector key.
Objectives : The acupoint-meridian relationship of an acupoint is one of important features of the acupoint. It has also shown evolutionary development over the history of medicine. This study analyzed the prototype kind of information on acupoint-meridian relationships in the A-B Classic of Acupuncture and Moxibustion(the Classic) of 2c BCE. Methods : The acupoint-meridian relationship of all the acupoints listed in the Classic was counted and reviewed in comparison with the information in the contemporary standard texts. Results : In comparison with the contemporary standard of 361 meridian points, the Classic listed 349(97%) acupoints. Of contemporary standard 361 points, 287(81%) acupoints still maintain the same acupoint-meridian relationship as in the Classic. Conclusions : Acupoint-meridian relationship in the Classic has largely been maintained throughout the history and still comprises a major proportion of the contemporary body of knowledge on acupoint-meridian relationship.

This paper discusses this seminar's theme, 'Classic Literature Enjoyment Methods and Education,' with a focus on the genre of classic poems. However it does not focus on any individual method by discussing a specific genre or enjoyment method but focuses on a fundamental discussion. The importance of a functional relationship between the classic poetry genre and its enjoyment method is raised avoiding a generalized discussion. There are things that researchers often forget about classic poems. They forget that most classic poems are not ordinary poems but songs that are to be sung, and thus they should, in principle, be expressed in Korean language. These two facts about classic poems, indicate that their enjoyment method should be given importance. Compared to modern poems, Chinese classic poems, folk songs, and other forms of verse, only classic poems have the aforementioned conditions unique to them. In addition, classic poems include several types of poems, Japga (literally, miscellaneous songs), and Siga (literally, poem-song) genres representing each era, so it is important to discuss the characteristics of such poems with respect to their times periods and genres. Even based on such characteristics, the enjoyment situation where works are created and sung in the genre of classic poems is very important, and thus the enjoyment method issue should be closely linked with the study of works and genres. This study examines how the topics of enjoyment methods for classic poems is reflected in the current middle education curriculum. To improve the current situation, it outlines the issues that arise when enjoyment methods for classic poems are applied to textbooks or classes, set as textbook unit goals or criteria for achievement, and presented as measures designed to plan the composition of works and learning activities. Future studies on literary educational methodologies are expected to further examine the enjoyment methods for poems in class discussed herein.
Objective : I refered to oriental medical records to study on the use Ohaeng-acupuncture through compared ${\ll}$Classic on Difficulty${\gg}$ with . Methods : The original text about ${\ll}$Classic on Difficulty${\gg}$ was used ${\ll}$Nan Jing Ben YI${\gg}$, annotations were excerpted and record that were necessary for this study. The structural formula was composed together to compare ${\ll}$Classic on Difficulty${\gg}$ with . Results : ${\ll}$Classic on Difficulty${\gg}$ deals with fundamental medical theories and gives differentiation of syndromes of some diseases in the form of questions and answers. ${\ll}$The Sixty nineth Difficulty, Classic on Difficulty${\gg}$ 'Xu Ze Bu Qi Mu(虛者補其母), Shi Ze Xie Qi Zi (實者瀉其子)' that united ${\ll}$Ling Shu(靈樞) - Jing Mai(經脈篇)${\gg}$ 'Sheng Ze Xie Zhi(盛則瀉之) Xu Ze Bu Zhi(虛則補之)' with Ohaeng-xiangsheng theory is the base of the 'Bu Xie (補瀉)'. ${\ll}$The seventy fifth Difficulty, Classic on Difficulty${\gg}$ 'Xie Nan Huo (瀉南方火) Bu Bei Shui (補北方火)' that based Ohaeng-xiangke theory and the 'Qu Xue(取穴)' takes the form of the 'Bu Mu Xie Zi (補母瀉子)' in standard of internal organs which are etiologic al cause named 'Shi(實)'.
Objectives: The objectives of this study are to determine both what information Korean Medicine(KM) doctors want from medical classics and how classic KM knowledge should be structured. Methods: KM doctor survey was conducted in October 2012 via E-mail to determine what information Korean Medicine doctors want to collect from a larger volume of existing classics. Specialist survey was made in October 2012 through questionnaire and 8 workshops were held between April 2012 ~ February 2013 to discuss how to reorganize classic KM knowledge. Results: With two surveys and 8 workshops, we built a conceptualization of the classic KM knowledge system for KM practice. KM doctors wanted to engage with the design of KM knowledge system informed by authentic medical classics, and hoped that more information on common disorders would be added to the table of contents of classic KM books than now. A comprehensive knowledge system was also required to maximize information sharing. Conclusions: Future KM knowledge systems need to be more comprehensive and include more information about disorders with which patients commonly consult KM doctors.
The purpose of this study is twofold: it suggests appropriate sizes in menswear slim-fit jackets according to brand zones and number of buttons, as well as jacket patternmaking methods according to jacket styles by surveying and comparing the overall present status of patternmaking and production for both men's slim-fit and classic-fit jackets. The researcher conducted interviews with patternmakers of sixteen brands with prepared questionnaires. Data were analyzed by descriptive statistics using SPSS 12.0. The results of this study are as follows: first, for the production ratios of jacket style, the jacket styles' respective proportions differ distinctly according to brand zone. Second, for a jacket with the same number of buttons according to brand zone, the size in character-casual brand zone (character casual can be defined as high quality brands producing designer style clothes) is slightly bigger than the men's formal suit. As the number of buttons increases, there are increases in the chest, waist and hip circumference; on the other hand, the front neck width and the distance from the shoulder neck point to the bottom of the lapel both decrease. Furthermore, the amount of wearing ease in the chest, waist, upper arm circumference, and sleeve curve is less in slim-fit jacket styles than in classic-fit jacket styles. Fusible interfacing alone is used in slim-fit jackets, while sew-in interfacing is used in combination with fusible interfacing in classic-fit jackets. This research concludes that when slim-fit men's jackets are manufactured, appropriate patternmaking and manufacturing methods should be considered.
Objectives : Wrist ganglion is one of the most common diseases on the wrist joint. So far acupuncture, medication, drainage and local anesthetic excision therapy have been used for this disease, but the development of more effective treatment method is being expected because of frequent recurrence and side effect. Considered that most ganglion is polycystic, on the basis of classic centro-square acupuncture, newly transformed centro-square acupuncture was applied to this report. Methods : All the patients with wrist ganglion was divided into two groups. Newly transformed centro-square acupuncture was app(ied to one group composed of 11 patients and classic centro-square acupuncture to the other group with 19 patients. Classic centro-square acupuncture is made up of slanting and straight insertion. the former is a method that tips of 4 needles are inserted from the outersurface of wrist ganglion oriented to the center of the ganglion, the latter is that tip of one needle is inserted on the center of the ganglion straightly. In the newly transformed centro-square acupuncture, straight insertion of dry needle was taken place of by syringe needle in order to drain phlegm. In this report, classic and newly transformed centro-square acupuncture were used somewhat differently from original ones. Moxibustion was applied after removing all the needles. In newly transformed centro-square acupuncture, moxibustion was also applied after drainage of phlegm and slanting insertion. Results : 1. Wrist ganglion was frequently developed around the acupoint of Tae-Yeon(Tai Yuan, LU9) and Yang-Ji(Yang Chi, TE4) and the difference between occurrence of development on the left and right hand had no significancy. 2. The mean number of treatment for recovery : The newly transformed centro-square acupuncture had fewer treatment than classic one. 3. The newly transformed centro-square acupuncture was more effective than classic one. 4. As a result of following up 6 to 72 months after wrist ganglion had been eliminated, there was no recurrence. Conclusion : In the treatment of wrist ganglion, newly transformed centro-square acupuncture can be regarded as more useful method in the clinical practice, because it has comparatiely shorter duration of treatment and is more effective.
Background: Mantle-cell lymphoma (MCL) is a unique entity of peripheral B-cell lymphoma that has a discrete morphologic, immunologic, and genetic phenotype, with more common 'classic' and less frequent 'blastoid' and 'pleomorphic' variants, associated with an aggressive clinical course. The aim of this study was to analyze proliferation (Ki-67) indices of 'classic' (c-MCL) and 'blastoid' (b-MCL) variants of a cohort of MCL and to suggest cut off values for the Ki-67 proliferation index in these two subsets. Materials and Methods: MCL cases diagnosed over $4{\frac{1}{2}}$ years at Section of Histopathology, Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi were retrieved and reviewed. Ki-67 labelling was scored and analysed. Results: A total of 90 of cases of MCL were scrutinized. Mean age ${\pm}SD$ was $60.2{\pm}12.5$ years and the male to female ratio was 4:1, with 67 (75%) cases of c-MCL and 23 (25%) cases of b-MCL. Most samples were lymph node biopsies (n=68), whereas the remainder were from various extranodal sites The mean Ki-67 proliferation index was $29.5%{\pm}14.4%$ in classic variants and $64.4{\pm}15.2%$ for the blastoid variant, the difference being statistically significant (p = 0.029). Conclusions: It was concluded that differential cut-off values of Ki-67 labeling may be used in more objective way to reliably classify MCL into classic or blastoid variants by diagnostic pathologists. We propose a < 40 proliferative index to be suggestive of c-MCL and one of > 50 for the blastoid variant.

Purpose: There is little controversy that a classic indication such as hemodynamic instability or any sign of peritoneal irritation requires an immediate laparotomy in the management of abdominal stab wounds. However, omental herniation or bowel evisceration as an indication for an immediate laparotomy is controversial. The purpose of this study was to evaluate the significance of these factors as indications for an immediate laparotomy. Methods: The medical records of 98 consecutive abdominal stab wounds patients admitted to the Emergency Center of Masan Samsung Hospital from January 2000 to December 2006 were carefully examined retrospectively. Using multivariate logistic regression analysis, thirty-nine factors, including the classic indication and intraabdominal organ evisceration, were evaluated and were found to be associated with a need for a laparotomy. Also, the classic indication was compared with a new indication consisting of components of the classic indication and intra-abdominal organ evisceration by constructing a contingency table according to the need for a laparotomy. Results: Multivariate logistic regression analysis revealed any sign of peritoneal irritation, base deficit, and age to be significant factors associated with the need for a laparotomy (p<0.05). The sensitivity, specificity, and accuracy rates of the classic indication were 98.6%, 72.0%, and 91.8%, respectively, and those of the new indication were 93.2%, 84.0%, and 90.8%, respectively. The differences in those rates between the above two indications were not significant. Conclusion: Intra-abdominal organ evisceration was not a significant factor for an immediate laparotomy. Moreover, the new indication including intra-abdominal organ evisceration was not superior to the classic indication. Therefore, in the management of abdominal stab wounds, the authors suggest that an immediate laparotomy should be performed on patients with hemodynamic instability or with any sign of peritoneal irritation.
