Various statistical classification methods have been used to establish prediction model of underground cultural assets in our country. Among them, linear discriminant analysis, logistic regression, decision tree, neural network, and support vector machines are used in this paper. We introduced the basic concepts of above-mentioned classification methods and applied these to the analyses of real data of I city. As a results, five different prediction models are suggested. And also model comparisons are executed by suggesting correct classification rates of the fitted models. To see the applicability of the suggested models for a new data set, simulations are carried out. R packages and programs are used in real data analyses and simulations. Especially, the detailed executing processes by R are provided for the other analyser of related area.

Korea is currently an aging society with a population of about 15 percent over the age of 65. Accordingly, the government is currently working on a number of measures. However, the problem that is rapidly increasing rather than decreasing is the traffic accident of the elderly. It has increased so much that we can check it out in multiple media right away. An average of 110 elderly people die or are injured in traffic accidents a day, or about 40,000 a year. The National Police Agency reported a 25 percent increase in elderly traffic accidents from five years ago. This paper analyzes traffic accidents of senior citizens through the Big Data analysis and R programming language to present the main causes of traffic accidents of senior citizens and areas where measures are needed to prevent them.

In previous research, we suggested a business process structured query language(BPSQL) for information extraction and retrieval in the business process framework, and used an existing query language with the tablization for each layer within the framework, but still had a problem to manually build with the specification of each layer information of BFP. To solve this problem, we suggest automatically to build the schema based business process model with model-to-text conversion technique. This procedure consists of 1) defining each meta-model of the entire structure and of database schema, and 2) also defining model transformation rules for it. With this procedure, we can automatically transform from defining through meta-modeling of an integrated information system designed to the schema based model information table specification defined of the entire layer each layer specification with model-to-text conversion techniques. It is possible to develop the efficiently integrated information system.

Background and Objectives : The purpose of this study was to examine objectively pre and post operative voice quality evaluation and intelligibility of alaryngeal voice using speech recognition program, HUVOIS. Materials and Methods : 2 laryngologists and 1 speech pathologist were evaluated 'G', 'R', 'B' in the GRBAS sclae and speech intelligibility using NTID rating scale from standard paragraph. And also acoustic estimates such as jitter, shimmer, HNR were obtained from Lx Speech Studio. Results : Speech recognition rate was not significantly different between pre and post operation for pathological vocie samples though voice quality(G, B) and acoustic values(Jitter, HNR) were significantly improved after post operation. In Alaryngeal voices, reed type electrolarynx 'Moksori' was the highest both speech intelligibility and speech recognition rate, whereas esophageal speech was the lowest. Coefficient correlation of speech intelligibility and speech recognition rate was found in alaryngeal voices, but not in pathological voices. Conclusion : Current study was not proved speech recognition program, HUVOIS during telephone program was not objective and efficient method for assisting subjective GRBAS scale.

Background and Objectives : Accent method is one of holistic approaches for behavior readjustment of voice therapy The aim of this study is to evaluate the efficacy of the accent method of voice therapy for the patients who have no improvement after LMS. Materials and Methods : Of the patients who had been undergone LMS during the period from Jan. 1999 to Dec. 1999, medical records of 38 patients who had not been improved were studied retrospectively. 19 patients(treatment group) were applied accent method and the other 19 patients(control group) refused voice therapy. The voice of all the patients of both group were analysed with CSL and Aerophone II programs in pre- and post operative period. The voice of treatment group were analysed with Visi-Pitch II program before the application of accent method and after the completion of accent method. Then, the results were compared using paired t-test. Results : The results of voice analysis were not different statistically between pre- and postoperative examination in both group. After application of accent method in the treatment group, fundamental frequency(F$_{0}$) of male, relative average pertubation, and shimmer were revealed significant differences(p＜0.01), and decrease in grade(G) scale and roughness(R) scale were statistically Important in perceptual analysis using GRBAS criteria(p＜0.01). But $F_0$ of female, maximal phonation time and S to Z ratio were not revealed significant differences. Conclusions : Accent method of voice therapy may be as a supplement- ary therapy in the patients who were not improved after surgery.

Elegie und Iambos gehoren zu den altesten Genre der griechischen Lyrik. Erst in diesen Gedichten aus den 7. Jh. v. Chr. beginnt der Dichter als pers nliches Subjekt seine eigenen Erfahrungen auszusprechen, w hrend or im Epos objektiv und leidenschaftslos hinter seinem Stoff zur ckblieb. So behauptet man, dass in den Gedichten der beiden Genre 'das Erwachen der Personlichkeit' (B. Snell) erfolge. Doch dieser pers nliche Charakter der fruhgriechischen Dichtung darf nicht im Sinne der Subjektivit t verstanden werden, wie man sie in der modernen Lyrik findet. Dem subjektiven Gef hl, das in den uns tradierten Fragmenten aus der fr hgriechischen Dichtung zum Ausdruck kommt, kann man n mlich ein gemeinsames Pathos ablesen, das die Elegiker und Iambographen in der Zeit des politischen Umwandels angesichts der conditio humana empfunden batten, das Pathos n mlich, das sich wohl unter dem Begriff amechanie am besten zusammenfassen lasst. In solchen Grenzsituationen, wie Krieg, Ungluck, Altern, sprechen sich die Dichter vollig hilflos aus und beklagen sich uber die menschliche Unwissenheit uber das erh ngte Schicksal. Bezeichnend f r ihre Begegnung mil der Hilflosigkeit des menschlichen Daseins ist jedoch der Realit tssinn, den sie aus ihren Erfahrungen der conditio humara bzw. amechanie gewonnen haben: Sie wollen sich weder durch einen heroischen Gedanken uber den Nachruhm noch durch einen religiosen Glauben an das Jenseits tauschen lassen. Sie wollen vielmehr hic et nunc einen Weg finden, sich mit der amechanie abzufinden. Und dabei werden zwei verschiedene Lebenswege eingeschlagen, der Weg des erotischen Hedonismus (Mimnermos und Semonides) und der des 'sardonischen' Realismus (Archilochos). Damit weisen uns die fruhgriechische Lyrik auf zwei typische Lebensrichtungen hin, die sich spater in der griechischen Ethik einb rgern sollen.

The present study was performed to investigate the voice onset time(VOT) of Korean stop consonants as the expanded research of Pyo and Choi(1996) : the intensity, and the air flow rate of Korean stops as the preliminary study f3r the classical singing training. Nine Korean stops(/P, P', $P^{h}$/, /t, t', $t^{h}$/, /k, k', $k^{h}$/) and a vowel /a/ were used as speech materials. CV and VCV syllable patterns were used for VOT measurement, and CV pattern was used for intensity and air flow rate measurement. Five males and five females pronounced the speech tasks with comfortable pitch and intensity : VOT, intensity, and air flow rate were measured. As results, the prevocalic stop consonants showed bilabials, the shortest VOT and velars, the longest one, except the unaspirated stops which showed the shortest was velar /k'/, and the alveolar /t'/ was the longest. Considering the tensity, heavily aspirated stops showed the longest, and the unaspirated, the shortest. Also the intervocalic stops showed similar results with the prevocalic stops, except the slightly aspirated stops which showed alveolar sound was the longest, and the bilabials, which showed the shortest was the slightly aspirated /p/, unlike the prevocalic stops, the unaspirated /p'/ the shortest. All of prevocalic stops showed the highest air flow rate in heavily aspirated stops, the second, thee slightly aspirated ones, and the lowest was the unaspirated stops. And as a whole, bilabials were the highest, and velars, the lowest, except in the heavily aspirated stops, which was the alveolar sound, the lowest. In the dimension of intensity, the unaspirated and bilabials were the highest, and the heavily aspirated and velars were e lowest, except the slightly aspirated stops, which were the bilabials the lowest, and the alveolars the highest.

Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16 MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with two complete blood count analyzers (Sysmex WE-8000 and Coulter STKS) for unidirectional data transmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology.

Background and Objectives The Voice Perceived Present Control scale (VPPC) has been developed to provide better insight into patients' perceived control over their thoughts or behaviors related to voice disorders. The objective of the present study was to validate the Korean VPPC (K-VPPC) by evaluating its internal consistency and reliability. Materials and Method All items of the English VPPC were translated into Korean. Content validity was analyzed through three Delphi survey rounds by an expert panel (n=44) with active clinical and research experience in treating dysphonic patients. Twenty-three patients with a heterogeneous diagnosis of dysphonia and twenty-three gender-matched vocally normal controls (total n=46) were asked to complete the K-VPPC and the Korean Voice Handicap Index-10 (KVHI-10). Psychometric properties including internal consistency and reliability were evaluated to examine the appropriateness of cross-cultural use of K-VPPC. Results Cronbach's alpha coefficient of K-VPPC was 0.89 for dysphonic patients, indicating good internal consistency in clinical samples. Furthermore, patients with dysphonia scored significantly lower on the total score of K-VPPC and higher on voice handicap than the vocally normal controls. Spearman's correlation coefficients indicated an inverse and moderate association between the K-VPPC and all domains of KVHI-10 (Spearman's r=-0.44- -0.68). Conclusion The findings of the current study indicated that the K-VPPC is a valid and reliable tool for the assessment of perceived control in Korean patients with dysphonia. Therefore, the K-VPPC could be a useful and complementary tool for the comprehensive evaluation of dysphonia, thereby improving care in Korean patients with voice disorders.
