Among the various dysarthric subtypes, diagnosis of ataxic dysarthria is rendered when the speech characteristics include imprecise and irregular articulatory breakdowns, marked degree of speech rate impairment, overall monopitch and monoloudness, and respiratory-articulatory incoordination. Traditionally, speech pathologists have relied only upon their ‘ears’ to describe and evaluate the dysarthric speech. A statement of percentage of correct words identified by a listener do not provide so much more than an index of severity. Within the same perceptual dimension, a carefully constructed speech intelligibility test can specify patterns of errors. The patterns can contain a diagnostic value as well as Provide strategies for remediation. The phonetically transcribed texts on single words and a standard passage, 'kail' produced by an ataxic dysarthria are presented in this report, with an emphasis of the articulatory error analysis. Furthermore,, acoustic tools [e.g., spectrography to measure formant transitions, segment durations, consonant spectra, etc.] are utilized to serve as basic measures that objectively document patients' speech intelligibility, Finally, the treatment methods [e.g., spectrography as a visual feedback, gestural reorganization using pacing method, DAF (Delayed Auditory Feedback)] to modify the dysarthric behaviors are presented.

This study attempts to reorganize the knowledge classification system for the research fields and majors in education by designing a new classification schedule. Content analysis of the majors and curriculums in the universities and major areas of the academic professors in Korea, and the comparison with the various headings in several classification systems for research fields were carried out. Based upon the comparison with library classification systems and reviews and opinions of subject specialists in major disciplines, finally, a knowledge classification system composed of three parts - schedules, tables and a relative index - was presented. The proposed classification scheme was tested for classifying the research projects listed in the 1998 catalog of the academic research funded by Korea Research Foundation. Also, several ways for developing a more useful knowledge classification scheme to organize disciplinary information effectively and to encourage interdisciplinary research were suggested.

Identity authentication is a crucial line of defense for network security, and passwords are still the mainstream of identity authentication. So far trawling password attacking has been extensively studied, but the research related with personal information is always sporadic. Probabilistic context-free grammar (PCFG) and Markov chain-based models perform greatly well in trawling guessing. In this paper we propose a systematic targeted attacking model based on structure partition and string reorganization by migrating the above two models to targeted attacking, denoted as TG-SPSR. In structure partition phase, besides dividing passwords to basic structure similar to PCFG, we additionally define a trajectory-based keyboard pattern in the basic grammar and introduce index bits to accurately characterize the position of special characters. Moreover, we also construct a BiLSTM recurrent neural network classifier to characterize the behavior of password reuse and modification after defining nine kinds of modification rules. Extensive experimental results indicate that in online attacking, TG-SPSR outperforms traditional trawling attacking algorithms by average about 275%, and respectively outperforms its foremost counterparts, Personal-PCFG, TarGuess-I, by about 70% and 19%; In offline attacking, TG-SPSR outperforms traditional trawling attacking algorithms by average about 90%, outperforms Personal-PCFG and TarGuess-I by 85% and 30%, respectively.

The TPR-tree exploits bounding rectangles based on the function of time in order to index moving objects. As time passes on, each edge of a BR expands with the fastest velocity vector. Since the expansion of the BR results in a serious overlaps between neighboring nodes, the performance of range query is getting worse. In this paper, we propose schemes to reorganize bounding rectangles of nodes. When inserting a moving object, we exploit a forced merging scheme to merge two overlapped nodes and re-split it. When deleting a moving object, we used forced reinsertion schemes to reinsert other objects of a node into a tree. The forced reinsertion schemes are classified into a deleted node reinsertion scheme and an overlapped nodes reinsertion scheme. The overlapped nodes reinsertion scheme outperforms the forced merging scheme and the deleted node reinsertion scheme in all experiments.

This study analyses the current status of trade in Korean fisheries and competitive power in export to China in the era of actual open-door policy, aiming to figure out problems in distribution Structure of fisheries and suggest directions for further development in this area. Political efforts have been consistently made to change distribution system of our fisheries into low-cost and high-efficiency system, but continuous contradictions occur in actual distribution. In this reality, we need a new perspective to reorganize distribution markets according to real conditions. To improve distribution Structures for fisheries, political focus should be given on reorganization of the entire structure. And to develop political directions for fisheries, we should evaluate its competitive powers and based on the results, we should develop efficient measures to use limited political resources.

PET-CT and PET-MRI which integrates CT using ionized radiation and MRI using phenomena of magnetic resonance are determined to have the limitation to apply the semi-quantitative index, standardized uptake value (SUV), with the same level due to the fundamental differences of image capturing principle and reorganization, hence, their correlations were analyzed to provide their clinical information. To 30 study subjects maintaining pre-treatment, $^{18}F-FDG$ (5.18 MBq/㎏) was injected and they were scanned continuously without delaying time using $Biograph^{TM}$ mMR 3T (Siemens, Munich) and Biograph mCT 64 (Siemens, Germany), which is an integral type, under the optimized condition except the structural differences of both scanners. Upon the measurement results of $SUV_{max}$ setting volume region of interest with evenly distributed radioactive pharmaceuticals by captured images, $SUV_{max}$ mean values of PET-CT and PET-MRI were $2.94{\pm}0.55$ and $2.45{\pm}0.52$, respectively, and the value of PET-MRI was measured lower by $-20.85{\pm}7.26%$ than that of PET-CT. Also, there was a statistically significant difference in SUVs between two scanners (P<0.001), hence, SUV of PET-CT and PET-MRI cannot express the clinical meanings in the same level. Therefore, in case of the patients who undergo cross follow-up tests with PET-CT and PET-MRI, diagnostic information should be analyzed considering the conditions of SUV differences in both scanners.

The Cultural Revolution(wenhuadageming) is one of the most important political movement in the modem China. The studies on the movement done in recent years concentrated on the political conspiracy or the struggle over political line, so they did not pay attention to the political geographical dimension of the movement. This paper proposes that the Cultural Revolution practised in the area of minority nationalities at least is well understood through the political geographical perspective. Through the discussion on the Cultural Revolution practised in the Inner Mongolia autonomous district and the Oroqen minority nationality autonomous banner, this paper suggest that the socialist Chinese leader group considers the frontier area(bianjiang) or the minority nationality regions(xiaoshuminzudiqu) important as 'region' or 'space' not as 'the area of minority nationalities (minzu)'. Especially, in the period of the movement, the leader group of the revolution manipulated the space by using the index of nationality or manipulated the nationality by using the index of space. Therefore this paper assert that the Cultural Revolution in the area of minority nationality autonomous region was a integration process of the people and national territory through the reorganization of the nationalities into classes and of autonomous region into region in general meaning.

The purpose of this study was to understand clothing condition of elderly men focusing on somatotype variation and satisfaction with ready-to-wear and to provide basic data in designing ready-to-wrar for the elderly men. The questionnaire method was used and one-to-one interviews were held for the elderly residents in Seoul, Deajon, Jonju, and Yeosu areas. The total of 275 questionnaires (from 148 elderly men in the 60's, 99 in the 70's and 28 in the 80's) were collected and used for statistics. SAS package was used for the statistics and the statistics were based on frequency, X2-test, ANOVA, Duncan's multifle range test. The results of the study were as follows; 1) Height (p< .05), weight (p< .001) and Rohrer index (p< .05) decreased significantly with ageing 2) The somatotypes of 75.6% were changed and the 70's 8t the 80's showed significantly (p< .05) higher changing rate compared to the 60's and more changes took place significantly (p< .001) with ageing. 3) The most preferred out wear was suit & tie and next was jumper or shirt. 4) For the mode of getting suit, the highest number 55.3%) purchased ready-to-wear, next (32.0%) was tailored and the least (12.7%) neither purchased nor tailored. The percentage of buying ready-to-wear significantly (p< .01) decreased with ageing. The main reason for getting tailor-made was not well fitting of ready-to-wear (20.7% out of 32.0%). And for the mode of getting suit, there was significant differance with income (p< .001) and pocket money (p< .01). 5) The most important factors in suit and shirt werefirst, size (fitness) and second, comfort in movement. 6) For the wearing feeling of suit, 55.3% showed discomfort. There was significant difference according to the age (p< .05) and pocket money (p< .05). The Discomfort increased with ageing and less pocket money. 7) 62.4% answered it uneasy to Pick out well fitting If comfortable suit. This showed their dissatisfaction with ready-to-wear. 8) As for the items of not well fitting, 64.4% answered in jacket, 60.8% in trousers, 46.0% in shirt. The above result shows that elderly men's somatotype changes as they age, suit is found uncomfortable and it's not easy for elders to pick out comfortable ready-to-wear. So, they seem to have a certain dissatisfaction in ready to wear. Therefore, there is a need for reorganization of size and developing pattern design according to measurement of elderly men.

To train the manpower to meet the requirements of the industrial field, the introduction of the National Qualification Frameworks(hereinafter referred to as NQF) was determined in 2001 by National Competency Standards(hereinafter referred to as NCS) centrally of the Office for Government Policy Coordination. Also, for landscape architecture in the construction field, the "NCS -Landscape Architecture" pilot was developed in 2008 to be test operated for 3 years starting in 2009. Especially, as the 'realization of a competence-based society, not by educational background' was adopted as one of the major government projects in the Park Geun-Hye government(inaugurated in 2013) the NCS system was constructed on a nationwide scale as a detailed method for practicing this. However, in the case of the NCS developed by the nation, the ideal job performing abilities are specified, therefore there are weaknesses of not being able to reflect the actual operational problem differences in the student level between universities, problems of securing equipment and professors, and problems in the number of current curricula. For soft landing to practical curriculum, the process of clearly analyzing the gap between the current curriculum and the NCS must be preceded. Gap analysis is the initial stage methodology to reorganize the existing curriculum into NCS based curriculum, and based on the ability unit elements and performance standards for each NCS ability unit, the discrepancy between the existing curriculum within the department or the level of coincidence used a Likert scale of 1 to 5 to fill in and analyze. Thus, the universities wishing to operate NCS in the future measuring the level of coincidence and the gap between the current university curriculum and NCS can secure the basic tool to verify the applicability of NCS and the effectiveness of further development and operation. The advantages of reorganizing the curriculum through gap analysis are, first, that the government financial support project can be connected to provide quantitative index of the NCS adoption rate for each qualitative department, and, second, an objective standard is provided on the insufficiency or sufficiency when reorganizing to NCS based curriculum. In other words, when introducing in the subdivisions of the relevant NCS, the insufficient ability units and the ability unit elements can be extracted, and the supplementary matters for each ability unit element per existing subject can be extracted at the same time. There is an advantage providing directions for detailed class program and basic subject opening. The Ministry of Education and the Ministry of Employment and Labor must gather people from the industry to actively develop and supply the NCS standard a practical level to systematically reflect the requirements of the industrial field the educational training and qualification, and the universities wishing to apply NCS must reorganize the curriculum connecting work and qualification based on NCS. To enable this, the universities must consider the relevant industrial prospect and the relation between the faculty resources within the university and the local industry to clearly select the NCS subdivision to be applied. Afterwards, gap analysis must be used for the NCS based curriculum reorganization to establish the direction of the reorganization more objectively and rationally in order to participate in the process evaluation type qualification system efficiently.
