This book was completed in the 33rd year of Gang-hui-gapsul(康熙 甲戌) in the Cheong(淸) dynasty(1694), and was first inscribed in the 55th year of Geonryung(乾隆). In this first edition named 'Daechudangbon(大雅堂本)', his descendant Jinbonghui(陳鳳輝) wrote the postscript. There are also other editions such as 'Ga-gyeong-ganchwihyeondangbon(嘉慶間聚賢堂本)', 'Wimundanggeonsangbon(緯文堂巾箱本)' and 'Guangseo-ganseonseongdangbon(光緒間善成堂本)' Second, this book was called "Oe-gwabirok(外科秘錄)" and used the pen name 'Gibaekchunsasojeon(岐伯天師所傳)'. There are 16 volumes in total. The beginning of volume one, is a drawing of the 14 meridians. Volumes 1$\sim$4 are on the symptoms and treatment of abscesses and sores and ulcers[癰疽瘡瘍]. Volumes 5$\sim$13 are on surgery, dermatology and 156 diseases such as wounds by contusion, sharp objects and insects and beasts[跌撲, 金刃, 蟲獸傷]. Volumes 14$\sim$16 list the internal treatments, external medicine, acupuncture and moxibustion and surgery of sores and ulcers. Third, the book stressed early detection and treatment of diseases, emphasized inner resolving[內消] being cautious about using medicine, and further deepened the syndrome differentiation and treatment[辨證施治] of sores and ulcers[瘡瘍] by dividing fire toxin(火毒) into Eumhwa and Yanghwa(陰火/陽火). Also, it established the cause of sores and ulcers development as the deficiency of Gi(氣) and blood[血] and focused especially on the liver and kidney's involvement in the process. It also asserted that the pathogen[邪] is the tip[標], so one should eliminate and reinforce[攻補] to balance it out. The sore and ulcer surgery[瘡瘍外科] part is mostly based on detoxifying[解毒] and resolving[消散]. Although the meridians were mentioned, they were not emphasized, while moxibustion treatment of sores and ulcers[瘡瘍] were thoroughly analyzed. Also, of all 550 formulas in this book, 90% are experience-based which frequently use Geum-eunhwa(金銀花), Pogong-yeong(蒲公英) and Jahwajijeong(紫花地丁). The usages are unique, and the formulas have good adaptability. The symptoms of the diseases are explained first, followed by according main and sub treatments.

There was a large scale of DDoS(Distributed Denial of Service) attacks mostly targeted at Korean government web sites and cooperations's on March 4, 2010(3.4 DDoS attack) after 7.7 DDoS on July 7, 2009. In these days, anyone can create zombie PCs to attack someone's website with malware development toolkits and farther more improve their knowledge of hacking skills as well as toolkits because it has become easier to obtain these toolkits on line, For that trend, it has been difficult for computer security specialists to counteract DDoS attacks. In this paper, we will introduce an essential control list to prevent malware infection with live forensics techniques after analysis of monitoring network systems and PCs. Hopefully our suggestion of how to coordinate a security monitoring system in this paper will give a good guideline for cooperations who try to build their new systems or to secure their existing systems.

This paper suggests techniques to enhance coding time which is a problem in traditional fractal compression and to improve fidelity of reconstructed images by determining fractal coefficient through adaptive selection of block approximation formula. First, to reduce coding time, we construct a linear list of domain blocks of which characteristics is given by their luminance and variance and then we control block searching time according to the first permissible threshold value. Next, when employing three-level block partition, if a range block of minimum partition level cannot find a domain block which has a satisfying approximation error, There applied to 24-bpp color image compression and image techniques. The result did not occur a loss in the image quality of the image when using the encoding method, such as almost to the color in the RGB image compression rate and image quality, such as gray-level images and showed good.

This study investigated the preference and intake frequency of a list of 15 commonly available high sodium Malaysian foods/dishes, dis cretionary salt use, and their possible association with demographics, blood pressures and anthropometric measurements among 300 Malaysian university students (114 males, 186 females; 259 ethnic Chinese, 41 Indians; 220 lean, 80 overweight). French fries and instant soup noodle were found to be the most preferred and most frequently consumed salty food, respectively, while salted fish was least preferred and least frequently consumed. Males had a significantly higher intake frequency of at least 6 of the salty foods, but the preference of most salty foods was not significantly different between genders. Ethnic Chinese significantly preferred more and took more frequently traditional and conventional Malaysian foods like asam laksa (a Malaysian salty-sour-spicy noodle in fish stock), salted biscuits and salted vegetable, while Indians have more affinity and frequency towards eating salty Western foods. Body Mass Index was significantly negatively correlated with the intake frequency of canned/packet soup and salted fish while waist circumference was significantly positively correlated with the preference of instant noodle. Also, an increased preference of potato chips and intake frequency of salted biscuits seemed to lead to a decreased WHR. Other than these, all the other overweight/obesity indicators did not seem to fully correlate with the salty food preference and intake frequency. Nevertheless, the preference and intake frequency of asam laksa seemed to be significant negative predictors for blood pressures. Finally, increased preference and intake frequency of high sodium shrimp paste (belacan)-based foods like asam laksa and belacan fried rice seemed to discourage discretionary salt use. In conclusion, the preference and intake frequency of the high sodium belacan-based dish asam laksa seems to be a good predictor for ethnic difference, discretionary salt use and blood pressures.

In the postprocessing of Hangul recognition system, the storage structure of contextual information is an important matter for the recognition rate and speed of the entire system. Trie in general is used to represent the context as word dictionary, but the memory space efficiency of the structure is low. Therefore we propose a new structure for word dictionary that has better space efficiency and the equivalent merits of trie. Because Hangul is a compound language, the language can be represented by phonemes or by characters. In the representation by phonemes(P-mode) the retrieval is fast, but the space efficiency is low. In the representation by characters(C-mode) the space efficiency is high, but the retrieval is slow. In this paper the two representation methods are combined to form a hybrid representation(H-mode). At first an optimal level for the combination is selected by two characteristic curves of node utilization and dispersion. Then the input words are represented with trie structure by P-mode from the first to the optimal level, and the rest are represented with sequentially linked list structure by C-mode. The experimental results for the six kinds of word set show that the proposed structure is more efficient. This result is based on the fact that the retrieval for H-mode is as fast as P-mode and the space efficiency is as good as C-mode.

The EFDC model has been simplified to enhance the computing performance in hydrodynamic modeling. Water quality module and unnecessary conditional statements were deleted in subroutine list and memory allocation. The performance of the enhanced model (EFDC-E) was checked by applying EFDC and EFDC-E models to simulating the tidal flow in Mokpo coastal zone. Both two-dimensional models and threedimensional models have been applied and compared. Three-dimensional models showed better simulation results agreeing with observed currents than two-dimensional models. The simulation results of EFDC-E model gave good results agreeing with the simulation results of EFDC model and the observed data. The computing speed of EFDC-E model is improved 3 times faster than that of EFDC model in modeling hydrodynamic flow for real time of 3 days in both 2-dimensional modeling and 3-dimensional modeling. The EFDC-E model can be used widely for hydrodynamic modeling because of improved simulation speed.

Hydrogen cyanide (HCN) is present in both the particulate and vapor phase of cigarette mainstream smoke. It is one of the 44 harmful substances on Hoffmann's list and is known to be a major ciliatoxic agent in cigarette mainstream smoke. Typically the determination of HCN in cigarette mainstream smoke has been done through colorimetric and electrochemical techniques, such as UV-spectrophotometry (UV), continuous flow analyzer (CFA), ion chromatography (IC) and capillary GC-ECD. In particular, CFA commonly has been using analysis hydrogen cyanide in cigarette smoke and the basic principle is pyridine-pyrazolone reaction. In this study, the more optimized analytical method is suggested isonicotinic acid-pyrazolone reaction method than previous pyridine-pyrazolone reaction method, a commonly used method for the determination of cyanide in water and air, by CFA. Sample collection was optimized by trapping particulate and vapor phase of smoke separately. The optimum NaOH concentration of the trapping solution was shown to be 0.2 M. HCN was stable up to 6 hours in this concentration but only 3 hours in 0.1 M solution. The sensitivity of this method was fairly good and it might be used in analysis of HCN in cigarette mainstream smoke.

In this paper the author proposes a case study of a freshmen introduction to engineering design course ing LEGO Mindstorm NXT and analyzes the survey results of the course. The diffilculties are that this course should provide various aspects of design experiences to the students while not requiring the major knowledge and skills and it should attract the students to the engineering major. According to our case study LEGO mindstorm can be a good solution to this problem. The design experience with LEGO Mindstorm NXT provides students with various aspects of design experiences including defining problem, finding constraints and functions, exploring design space, and performing preliminary design, as well as fun. This paper also provides a project list that can be used for freshmen design experience including soccer game robots, line tracer, and vacuum cleaner etc.

This is the research on the observing annual customs, the annual custom foods and the application of the annual custom foods to the school foodservice. We sample 419 housewives live in Kyungnam area and 174 dieticians work at the primary and secondary schools. Annual customs the housewives and dieticians observe at high degree are Chuseok, Seolral, Jeongwoldaeboreum, Dongji, Chopail, Sambok etc. The housewives observe more Seolral, Chuseok and Dongji than the dieticians and the dieticians observe more Sambok than the housewives.(P<.001) When they provide school foodservice, the dieticians observe Dongji at the highest degree. In Kyungnam they eat most the gakjongnamul as annual custom foods on Chuseok and Seolral. They eat most ogokbap and mugeunnamul on Jeongwoldaeboreum, minarinamul on Chopail, and samgyetang on Sambok and patjuk on Dongji as the annual custom foods. Most of dieticians (94.3%) answer that it is good to provide annual custom foods as the school foodservice on annual customs. However, they indicate some practical problems to do such as inadequacy of the school cooking facilities, its not suiting students' tastes, etc. The rate of housewives' answers that we have to transmit annual customs is higher than that of dieticians.(P<.001) Seolral topped the list of annual customs both housewives and dieticians answer must be transmitted, followed by Chuseok, Jeongwoldaeboreum, Dongji. Dongji is followed by Chopail(P<.001) in the housewives' answers while Sambok(P<.001) in the dieticians' answers. Though most of the respondents know the origins, dates and details of annual customs they think must be transmitted, they don't know well those of the other ones. By their mothers both housewives and dieticians have come to know about annual customs and mostly affected. Secondly housewives affected by their mothers-in-law while dieticians by their school education.(P<.001)
