Background and purpose: Giu Ga Chu Yo(診家樞要) was written in the year 1359 by Hwal Su(滑壽) who was a famous oriental doctor between Won(元) and Myeong(明) dynasty. As specialized in sphygmology (脈學), this book was brought together most things about sphygmology(脈擧) before Won(元) dynasty by e author. Moreover he added the self-realized things to this book. Methods: In this book, besides a author's preface, there are all 20 chapters which are Chu Yo Hyeon Eon(權要玄言), Jwa U Su Bae Jang Bu Bu Wi(左右手配臟腑部位), O Jang(五臟), Sa Si Peong Maek(四時平脈), Nae Gyeong Sam Bu Maek Beop(內經三部脈法), Ho Heup Chim Bu Jeong O Jang Beop(呼吸沈浮定五臟法), In Ji Ha Gyeong Jung I Jeing O Jang Beop(因指下重以定五腑法), Sam Bu So Ju(三部所主), Ji Maek Su Beop(持脈手法), Maek Gwi Yu Sin(脈貴有神), Maek Eum Yang Yu Seong(脈陰陽類成), Gyeom Hyeon Maek Ryu(兼見脈類), Je Maek Ui Gi Ryu(諾脈宜忌類), Heom Je Sa Jeung Ryu(驗諸死症類), Sa Jeol Maek Ryu(死絶脈類), O Jang Dong Ji Maek(五藏動止脈), Bu In Maek Beop(婦人脈法), So A Mrek Beop(小兒脈法), Maek Sang Tong Hoe(脈象統會), Maek Sang Ga(脈象歌) and an epilogue in the end. Result and Conclusion: Looking into this book, we can know that it is very detail in analyzing item by item, bright and simple in explaining and it is very useful in studying pulse evaluation(脈診). In his preface, Hwal Su(辨壽) expresses his opinion with firm confidence that 'Do(道) of the World scattered in several scholarships and books of method and technique(術). Nothing of method and technique(力術) is more important than medicine. Nothing of medicine goes before pulse evaluation(脈診).' With such good reasons, as a student of sphygmology(脈學), I think this book is very valuable in studying pulse evaluation.' So I add Hangul suffixes(吐) to a part of this book and translate it into Korean.

Objectives : To research the needed Buddhistic ethical beliefs and psychotherapy from representative medical records of oriental medicine. Methods : The baseline data this research used is Myeong-Ui-Lyu-An, Sok-Myeong-Ui-Lyu-An, Ui-Bu-Jeol-Lok and from the variety of medical records; we extracted 22 medical records that refer to Buddhist thoughts. The sequence of medical records is determined by analyzing the contents of all medical records and grouping them by their categories. Results : The representative ethical mind that a doctor needs is the 'mercy thought' from Buddhism. This way, the doctor has 'pity' on patients and expects no reward for what he had done. 'Spells and religious beliefs developed into medical treatment procedures by Buddhism and oriental medicine psychotherapy. Using the belief that everything is made of the mind, which is the point of the 'Hwa-Eum' theory and the realization that the psychotic factors have a big role in the occurrence and progress of sicknesses, we emphasized supportive psychotherapy or more specifically, the suggestive therapy. 'Anguish' is an important point in the occurrence and progress of illnesses. To solve this, we used 'Zen family's 'Zen self-discipline' and ascetic life from Buddhism. According to Buddhism, a human's metal conflict and love or malingering from obsession is the cause of all mind illnesses. To heal these, a doctor must have an insight of the patient's mind more than the symptoms. Conclusions : Buddhistic thoughts suggested clearly the mentality necessary for oriental medical psychotherapist and medical ethics for a doctor.

The purpose of this study was to investigate the effect of various metal surface treatments and adhesive systems on the flexural bond strength of composite resin to Au-Ag-Cu-Pd alloy. The specimens were divided into nine groups by the combinations of surface treatment methods and adhesive systems. The types of surface treatment in this study were alumina blasting only, alumina blasting-Sn plating, alumina blasting-heating and three kinds of adhesive system used in this study were Silicoater system(Heraeus Kulzer GmbH,Germany), Superbond C & B(Sun Medical Co.,Ltd.,Japan) and Cesead opaque primer(Kurary Co.,Ltd.,Japan). After surface treatments and adhesive systems were applied, each specimen was built up with Dentacolor composite resin (Heraeus Kulzer GmbH,Germany). Four-point flexural bond strength was measured by Instron universal testing machine (Model 4301,U.S.A.) and modes of failure were observed by SEM(JEOL,SSM-840A,Japan). The obtained results were as follows: 1. The group that was bonded with Superbond C & B after alumina blasting-heating shelved the highest bond strength with significant difference among the groups, except the group with Cesead opaque primer after alumina blasting-Sn plating(P<0.05). 2. In the groups bonded with Cesead opaque primer, there was significant difference only in the bond strength between the alumina blasting-Sn plating group and alumina blasting group, where the former showed a higher bond strength(P<0.05). 3. In the groups bonded with Silicoater system, there were no significant differences in bond strength regardless of the surface treatment method(P<0.05). 4. In SEM evaluation, the groups of high bond strength, especially bonded with Superbond C & B after alumina blasting-heating and Cesead opaque primer after alumina blasting-Sn plating, revealed mainly cohesive-adhesive failure, whereas the others showed the tendency of adhesive failure.

In order to observe the anticellulolytic localization in the epithelia of the digestive tract such as esophagus, crop, and intestine of a Korean land snail N. samarangae, a cytochemical method and a immunogold labelling method were applied. For the cytochemical study on the cellulase activity, Benedict reaction method applied. And for the immunocytochemical study, the rabbit serum immunoglobuins (IgG) was obtained from the rabbits injected with cellulase which was extracted from body fluid of the snail. The digestive tract tissues of N. samarangae were fixed with 4% paraformaldehyde and 2% OsO4 and embedded in Lowicryl K4M at -40$^{\circ}C$ under UV light (360 nm). The thin sections were loaded on the nickel grids and stained with the serum IgG and protein A-gold complex (particle size: 10 nm). Observations were undertaken with transmission electron microscope (Jeol, JEM-1010). The epithelium of the digestive tract was consisted of five types of cells. In the cytochemical study, the reaction products were found along the periphery of the vacuoles derived from the Bebedict reaction. In the immunocytochemical study, the protein-A gold particles were selectively labelled in Type 1, Type 3 and Type 4 cells in intestinal tissue. membranes of rER, in the surrounding cytoplasm of the rER and secretory granules, and in the apical cytoplasm of the cells. On the material being secreted from the apical cytoplasm was also labelled with the immunogold particles. The all results obtained throughtout present study suggest that the intestinal epithelium of the snail N. samarangae seretes cellulase as one of digestive enzymes.

Recently, systems based on speech recognition interface such as telematics terminals are being developed. However, many errors still exist in speech recognition and then studies about error correction are actively conducting. This paper proposes an error correction in post-processing of the speech recognition based on features of Korean phoneme. To support this algorithm, we used the phoneme similarity considering features of Korean phoneme. The phoneme similarity, which is utilized in this paper, rams data by mono-phoneme, and uses MFCC and LPC to extract feature in each Korean phoneme. In addition, the phoneme similarity uses a Bhattacharrya distance measure to get the similarity between one phoneme and the other. By using the phoneme similarity, the error of eo-jeol that may not be morphologically analyzed could be corrected. Also, the syllable recovery and morphological analysis are performed again. The results of the experiment show the improvement of 7.5% and 5.3% for each of MFCC and LPC.

There would be a long-waited launch of a Korean space launch vehicle(KSLV-I) in NARO Space Center which is located in Goheung, Jeol La Nam Do in Korea. Korea would be the nineth country in the world which could launch space launch vehicle itself. The launch of the 2nd technology satellite of 100kg with KSLV-I would give Korean hope and dream. In addition to the traditional space activities of U.S.A. and Russia, Japan launched the lunar satellite, Kaguya in 2007, China launched the lunar satellite, Change and succeeded in space walk and India launched the lunar satellite Chandrayaan in October, 2008. In this paper we study on the trend of domestic and international development of space launch vehicle considering all these space development activities.

A FOV (field-of-view) of the HV-MSC (high voltage multi-scan CCD, $1024{\times}1024$ pixels) camera mounted in the post-column HV-GIF (high voltage gatan image filter) has been drastically enlarged by the projection lens current adjustment. An imaging area of the HV-MSC camera obtained at the lowest magnification (2,000x) is $112{\mu}m^2$ which corresponds to the recording area of the film at the magnification of 8,800x, while the achievable recording area is only $0.43{\mu}m^2$ at the same magnification without this technique. Ignoring the image distortion of less than 5%, we have designed an on-site reference graph to estimate projection lens currents for microscope magnifications above 8,800x, where the recording area on the HVMSC is same as that on the film.

There are two problems which will be processed to graft a continuous speech recognition results into natural language processing technique. First, the speaking's unit isn't consistent with text's spacing unit. Second, when it is to be pronounced the phonological alternation phenomena occur inside morphemes or among morphemes. In this paper, we implement the postprocessing system of a continuous speech recognition that above all, solve two problems using the eo-jeol generator and syllable recoveror and morphologically analyze the generated results and then correct the failed results through the corrector. Our system experiments with two kinds of speech corpus, i.e., a primary school text book and editorial corpus. The successful percentage of the former is 93.72%, that of the latter is 92.26%. As results of experiment, we verified that our system is stable regardless the sorts of corpus.

Objectives: Persistent organic pollutants (POPs) are known to be the detrimental chemicals in the body, even at low levels, and are stored in adipose tissue. Recently, POPs have been reported to be associated with chronic diseases, including cancer and cardiovascular disease, and aging and obesity are reported as common factors in chronic disease. However, there have been only a few studies on the associations of POPs with age and body mass index (BMI) in Korea. Therefore, we analyzed the associations of serum POPs levels with age and BMI in Korea. Methods: This cross-sectional study includes 444 subjects (253 men and 191 women) from the Korean Cancer Prevention Study-II (2004-2011). Serum levels of 33 polychlorinated biphenyls (PCBs) and 19 organochlorine pesticides (OCPs) were measured by a gas chromatographer (Agilent 6890) coupled to high resolution mass spectrometer (JEOL JMS-800D). Results: Concentrations of PCB 153 (men: 12.26 ng/g lipid, women: 10.50 ng/g lipid) and p,p'-DDE (men: 94.66 ng/g lipid, women: 96.66 ng/g lipid) were the highest among serum PCBs and OCPs, respectively. PCBs and OCPs were significantly positively correlated with age in both sexes. After adjustment for age, non-dioxin like PCBs were significantly negatively correlated with body mass in women. However, cis-heptachlor epoxide was significantly positively correlated with body mass index in both sexes. When analyzed by sex, stronger associations were shown between POPs and age in men and POPs and BMI in women. Conclusion: These results may provide baseline data for the study of POPs and for the health management field in Korea.

This study was done to evaluate the changes of enamel surface by interproximal stripping and recovery of it by polishing. The number of 34 1st premolars which had extracted for orthodontic treatment were selected as samples. Interproximal stripping was performed by hand with metal strip and strip placer (Dentaurum Co., Germany) and low speed handpiece with diamond disk (Superdiaflex, Germany). Polishing was performed by hand with plastic strip (3M Col) and low speed handpiece with whip-mix, DCPA (Dicalcium Phosphate, Anhydrous, $CaHPO_4$) powder and Sof-lex (3M Co. U.S.A.) polishing kit. Each groups were examined under the scanning electron microscope (JEOL Co., JSM-840A, Japan) and the following results were obtained: 1. The stripped group performed by metal strip and diamond disk altogether showed deep furrow on the enamel surface as wide as about $10{{\mu}m}$. 2. There could be seen more irregular scratched line in the group stripped by metal strip than that by diamond disk. 3. The polished group performed by plastic strip and DCPA powder showed slight smoothening of the edge of stripped furrow on the enamel surface without relation to the stripping method. 4. The polished group performed by Sof-lex progressive polishing kit could not avoid the formation of the furrows on the enamel surface according to the particle size without relation to the stripping method. 5. The polished group performed by the superfine polishing wheel, the final stage of Sof-lex polishing method showed shallow scratched line as wide as within about $2{{\mu}m}$ on the enamel surface without relation to the stripping method. 6. The interproximal stripped enamel surface could not recover its original surface texture by any kind of polishing methods.
