For the purpose of better understanding of RAD children, comparisons were performed about the developmental and psychopathological characteristics between RAD and PDD children. Study subjects were the children between the ages 2 and 6. who visitied SNUCH Child and Adolescent Psychiatry OPD or treated in Day Treatment Center during May, 1989 and Sep., 1991, diagnosed by the child psychiatrist as RAD or PDD according to DSM-III-R diagnostic criteria. A total of 40 children were included in the study. 20 were RAD(18 boys, 2 girls). 20 were PDD(20 boys). PEP was performed to all study subjects, by the raters blind to psychiatric diagnosis of each. And analysis was done about the level of developmental functioning score and psychopathological scores between RAD and PDD children. The results are as follows 'There were retardation on the general developmental functioning in RAD children, and the severity of retardation were lined up as perceptual ability>imitation>gross motor>cogitive language>eye-hand coordination>fine motor. Characteristics of psychopathology in RAD children were lined up by severity as language>play>relationship>affection >sensory. Group differences of the two shows on PDD group rejection score was significantly higher on the perception item. while RAD was superior on the perception emerging response. Differences of the psychopathology between two groups were on such areas as ; Affection, which was significantly higher on 'Absent' in RAD, while significantly higher on 'severe' in PDD children. On the interest for the play and materials. sensory and language areas, RAD children were significantly higher ratings on 'Absent' than PDD children.

UP Link is One of the commercial product which converts HTML to HDML convertor in order to show the internet www contents in the mobile environments. When UP browser accesses HTML pages, the agent in the UP Link controls the converter to change the HTML to the HDML, I-Mode, which is developed by NTT-Docomo of Japan, has many contents through the long and stable commercial service. Micro Explorer, which is developed by Stinger project, also has many additional function. In this paper, we designed and implemented WAP convertor which can accept C-HTML contents and mHTML contents. C-HTML format by I-Mode is a subset of HTML format, mHTML format by ME is similar to C-HTML, So the content provides can easily develop C-HTML contents compared with WAP and the other case. Since C-HTML, mHTML and WML are used under the mobile environment, the limited transmission capacity of one page is also similar. In order to make a match table. After that, we apply conversion algorithm on it. If we can not find matched element, we arrange some tags which only can be supported by WML to display in the best shape. By the result, we can convert over 90% contents.

This study identifies the terms frequently used together with energy in online science news articles and topics of the news reports to find out how the term energy is used in everyday life and to draw implications for science curriculum and instruction about energy. A total of 2,171 online news articles in science category published by 11 major newspaper companies in Korea for one year from March 1, 2018 were selected by using energy as a search term. As a result of natural language processing, a total of 51,224 sentences consisting of 507,901 words were compiled for analysis. Using the R program, term frequency analysis, semantic network analysis, and structural topic modeling were performed. The results show that the terms with exceptionally high frequencies were technology, research, and development, which reflected the characteristics of news articles that report new findings. On the other hand, terms used more than once per two articles were industry-related terms (industry, product, system, production, market) and terms that were sufficiently expected as energy-related terms such as 'electricity' and 'environment.' Meanwhile, 'sun', 'heat', 'temperature', and 'power generation', which are frequently used in energy-related science classes, also appeared as terms belonging to the highest frequency. From a network analysis, two clusters were found including terms related to industry and technology and terms related to basic science and research. From the analysis of terms paired with energy, it was also found that terms related to the use of energy such as 'energy efficiency,' 'energy saving,' and 'energy consumption' were the most frequently used. Out of 16 topics found, four contexts of energy were drawn including 'high-tech industry,' 'industry,' 'basic science,' and 'environment and health.' The results suggest that the introduction of the concept of energy degradation as a starting point for energy classes can be effective. It also shows the need to introduce high-tech industries or the context of environment and health into energy learning.

This study was performed for 7th grade students to analyze by leader style, the verbal interactions between students in a small group in an MBL(Microcomputer-Based Laboratory) experiment class. The study was performed after arranging the students into four kinds of groups, including groups with leaders of inclusive, persuasive, and alienating styles and a group with no clear leader. The analysis of total frequencies of verbal interaction revealed that the group with an inclusive leader showed the highest frequency of verbal interaction, followed by the group with a persuasive leader, an alienating leader and lastly, the group with no clear leader. The group with an inclusive leader showed the highest frequency of interaction from a cognitive aspect related to question(Q), response(R), making suggestion(MS), and receiving opinions(RO), while interactions from an affective aspect related to behavioral participation(BP) and students' attitudes(SA) were observed more often in a group including an alienating leader than in any other group. An analysis of characteristics of verbal interaction according to leader style showed that a group with an inclusive leader had a permissive atmosphere. It also showed that all members of the group actively participated in discussion and they had a sense of belonging and self-pride with their group. In a group with a persuasive leader, the leader took the lead of most experimental and discussion activities and he was rarely challenged by other students in the group. Rather, other group members showed a tendency to depend on their leader. In a group with an alienating leader, the relationship between leader and members of the group was not harmonious and unfiltered expressions of dissatisfaction and ignorance often took place. The leader's lack of concern about members' low achievement became an obstacle in active discussion. In a group with no clear leader, most interactions during discussion were short and simple. Many answers to the question given by their members were not clear and the interactions were sometimes interrupted for a short while.

In der vorliegenden Arbeit wurde versucht, eine $ad\"{a}quate\;Basis\;f\"{u}r$ die Untersuchung der indirekten Sprachhandlung dadurch zu schaffen, die das $Indirektheitsph\"{a}nomen$ konstituierenden sozial-kommunikativen Faktoren ans Licht zu bringen. Dazu $mu{\ss}ten\;zun\"{a}chst$ einige Unstimmigkeiten der Searleschen Theorie der indirekten Sprechakte, die lange Zeit in der linguistischen Pragmatik dominierte, auf ihre $Erkl\"{a}rungskraft$ sowie ihre Haltbarkeit hin $\"{u}berpr\"{u}ft$ werden. In dieser Theorie wird davon ausgegangen, mit einer indirekten $\"{A}u{\ss}erung\;w\"{u}rden zwei\;illokution\"{a}re$ Akte gleichzeitig realisiert. Diese Annahme beruht ihrerseits auf der Auffassung, dem Satz wohne eine $illokution\"{a}re$ Rolle inne, wie z.B. dem Interrogativsatz die Rolle der FRAGE. So ist die bei Tisch oft verwendete $\"{A}u{\ss}$erung 'Kannst du mir das Salz reichen?' einerseits aufgrund des Fragesatztyps FRAGE und andererseits aufgrund der ihr konventionell zuzuordnenden Funktion eine BITTE. Die Frage ist, ob dem sog. $sekund\"{a}r\;illokution\"{a}ren$ Akt, also in diesem Fall der FRAGE, der Handlungscharakter verliehen werden kann. Denn die Handlungsintention des Sprechers liegt eindeutig darin, vom $H\"{o}rer$ das Salz $\"{u}berreicht$ zu bekommen, und nicht darin, sich vom $H\"{o}rer$ etwa uber seine $F\"{a}higkeit$ zum Salzreichen zu informieren. Die schwerwiegendsten $M\"{a}ngel$ der Searleschen Analyse der Indirektheit liegen z.T. darin, bei der Bestimmung des kommunikativen Zwecks einer $\"{A}u{\ss}erung$ von den sprachlichen Eigenschaften des Satzes ausgegangen zu sein und nicht von dem $Proze{\ss}$ der gemeinsamen Sinnkonstituierung durch die Kommunikationsteilnehmer, wie etwa durch die gegenseitige Annahme und die reflexive Intention. In diesem Zusammenhang erweisen sich die-von Grice so genannten­partikularisierten konversationellen Implikaturen als das Musterbeispiel $f\"{u}r$ die Entstehung und Interpretation der indirekten $\"{A}u{\ss}erung$. Hier wird man vor allem - wenigstens auf der abstraktiven Ebene der Gegenstandsanalyse - der kommunikativen $Realit\"{a}t$ gerecht. Die kommunikative Indirektheit in der Alltagskommunikation, so $hei{\ss}t$ der allgemeinere Begriff als etwa die Indirektheit auf der $illokution\"{a}ren$ Ebene, zeichnet sich dadurch aus, $da{\ss}$ sie eine in besonderem $Ma{\ss}e$ partnerorientierte, kooperative und auf die $Intersubjektivit\"{a}t$ unter den Kommunikationsteilnehmem abzielende Handlungsweise darstellt.

An image processing system was built to evaluate the color properties of apple and meat. The system consisted of video camera, video card, 32 bit microcomputer and an optical illuminator. The operating software was developed to carry out capturing, analyzing, displaying and storing of the 8 bit digitized images of food. The images of apples at various maturing stages were investigated to obtain the color histogram of R, G, B and Hunter value. RGB histogram showed a major difference in G value, 35.01, the minor change in R value, 6.16, and the negligible difference in B value. The image of beef cut was separated into two parts, fat and lean tissue, by applying threshold value method based on the digital value of color. The threshold value for fat was over 240 and for lean under 230 in R value, respectively. The resulting non fat image showed 2% decreased color difference value, ${\Delta}E$, than whole meat cut.

The increased demand on the transport of both passengers and goods through rail systems implies higher traffic intensity and congestion on the railways, resulting in greater likelihood of accidents and also degraded passenger services. To cope with the issues, development of an integrated communication network for rails has attracted great deal of attention lately. GSM-R is such an example developed in Europe, which seems to have restrictions in providing various communication services due to network speed limit. For the reason, an LTE-based approach is under study in Korea. After the network development, operation management of the network is necessary. Design of operation management systems has been studied little and thus is the objective of this paper. To do so, a conceptual design has been carried out based on model-based approach. Specifically, a context model has first been created using the use case diagram. Then, SysML models of operational scenarios were developed for the management system. The SysML models have alternatively been expressed as EFFBD models to simulate and verify them. Consequently, the result of the conceptual system design for the operation management of the integrated wireless network is expected to be used as a basis for the detailed design later.

The present study aims to investigates the effects of the physical sound clarity (D50, STI) on the subjective speech intelligibility of the both Korean and Chinese languages which can be caused by increase of the sound absorption in classroom. In order to this, sound measurements were undertaken at a classroom with and without absorption materials. Also, speech intelligibility tests were conducted by Korean and Chinese students using their native languages. As the results, it was found that both sound clarity and speech intelligibility were improved with increasing sound absorption. Also, it was revealed that Chinese speech intelligibility was more improved than Korean with same impose of sound absorption. It was considered by the difference of phonetic characteristics of two languages. Analysing correlation of physical sound clarity and subjective speech intelligibility, it was shown that D50 is highly correlated with Korean (0.696) and Chinese (0.707) respectively. Also, STI was highly correlated with Korean (0.651) and Chinese (0.665). Thus, it can be concluded that D50 and STI have significant correlations with the speech intelligibility.

Background and Objectives : The effect of palliative injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients on voice and swallowing function is uncertain and there are few previous studies of its suitability, benefits as a palliative treatment option. The purpose of this study is to confirm the objective results of voice and swallowing function after palliative office-based hyaluronic acid injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients. Materials and Method : 36 patients who had unilateral vocal cord paralysis from non-thyroidal, extralaryngeal neoplasms were included in this study. To evaluate the clinical outcome, we analyzed perceptual GRBAS grading, acoustic analysis, aerodynamic study, Electroglottography (EGG), Voice Handicap Index (VHI-30) about voice function and disability rating scale (DRS), gastric tube dependency, aspiration pneumonia about swallowing function and 36-Item Short Form Survey version 2 (SF-36v2) about quality of life. Results : In GRBAS scale, G (p<0.001), R (p=0.004), B (p=0.001), A (p=0.011), and S (p=0.007) showed significant improvement. Jitter, shimmer, speaking fundamental frequency, maximal phonation time, VHI-30, DRS score, gastric tube dependency, aspiration pneumonia, and SF-36v2 were significantly improved after injection (p=0.016, p=0.011, p=0.045, p=0.005, p<0.001, p<0.001 p=0.003, p<0.001, and p<0.001 respectively). Conclusion : From this study we concluded office-based hyaluronic acid injection can be used as a useful palliative treatment option in cancer-related ill patients with unilateral vocal cord paralysis. Palliative hyaluronic acid injection laryngoplasty avoids the need for tube feeding, thus reducing the risk of aspiration pneumonia. These outcomes are accompanied by significant improvement in voice quality.
