Die vorliegende Arbeit setzt sich zur Aufgabe, nach einer Möglichkeit zu suchen, im DaF-Unterricht das Internet einzusetzen. Sie betrachtet drei Untersuchungsgegenstände hauptsächlich methodologisch, teilweise didaktisch. Mit der Entwicklung der Informations- und Kommunikationstechnologien eröffnen WWW-basierte/-unterstützte Lehren und Lernen neue Möglichkeiten für Fremdsprachenunterricht. Tendenziell spielt das Internet als neues und ergänzendes Kommunikationsmedium und Informationsquelle eine immer wichtigere Rolle. Das Internet als neues Medium bietet die Chance der Interaktivität im DaF-Unterricht, d.h., das Internet kann den Studentinnen und Studenten vor allem große Interessen und große Motivation für die deutsche Sprache bieten. In der Internetzeit kann der Lehrer nun nicht mehr der allwissenden Experte und Instruktor sein. Wichtiger werden das Beraten, das Anbieten von Hinweisen und Hilfestellungen. Das Internet stellt eine fast unbegrenzte Auswahl an aktuellen authentischen Texten mit Informationen über die deutschsprachige Länder zur Verfügung. Mit Hilfe der Webangebote können Lernende aktuelle Informationen über z.B. deutschsprachige Städte, Essen, Kultur und Alltagsleben usw. erhalten. Das Internet ist aber keine ganz perfekte Einsatzmöglichkeit im DaF-Unterricht. Trotzdem müssen Deutsch-Lehrende das Medium positiv im Unterricht einsetzen. Denn das Medium hat große Vorteile und verschiedene Möglichkeiten für den DaF-Unterricht. Daher müssen Deutsch- Lehrende das Internet als Lernmaterialsquelle für den Deutsch- unterricht benutzen und didaktisieren. Man kann die Radio-Sendungen ‘Deutsche Welle(DW)’ und ‘Westdeutscher Rundfunk(WDR)’ über Real Player hören. Man kann die Nachrichtentexte der DW abonnieren und erhält sie dann kostenlos per E-Mail zugesendet. Für Deutsch-Lehrende und Deutsch-Lernende bietet DW die “langsam-gesprochenen” Sendungen(unter dem Stichwort “Deutsch lernen mit Nachrichten”) mit Manuskripten und mp3-Dateien an. Man kann von Montag bis Freitag eine Spezial-Ausgabe der Nachrichten als Text und als Audio-on-Demand abrufen und herunterladen. Als Audio-Format bietet DW Real-G2 und MPEG an. Zum Offlinehören der mp3-Dateien kann man den mp3-Player “Winamp” herunterladen. Auf der Homepage der Deutschen Welle(http://www.dwelle.de/, seit kurzem http://dw-world.de/) werden die aktuellen Nachrichten direkt als RealVideo/RealAudio und Text angeboten. Auf der Homepage der Westdeutschen Rundfunks(http://www.wdr.de/) werden die aktuellen Nachrichten direkt als RealAudio und Text angeboten. Die Sendungen des WDR kann man beispielsweise mit Hilfe der Software ‘X-FileGet’ auf der Festplatte speichern. Allerding ist die Software ‘Total Recorder’(http://www.highcriteria.com/) stark empfehlenswert. Man sollte eventuell die aktuellen Meldungen des Tages auf der Festplatte speichern, um wiederholt anzuhören, d.h., um Hörverstehen der Deutsch-Lernende zu verbessern. Dazu sind einige Softwares für PC-Sound-Recording(z.B. Total Recorder, Sound Forge, X-FileGet etc.) erforderlich. Für Deutsch-Lernende sind die didaktisierten Radio-Nachrichten zusammen mit Text auf der Homepage wiederzugeben, um den DaF-Unterricht mit Hilfe des Internets zu geben. Deutsch-Lernende können im Unterricht mit Liedern sehr leicht und lustig durch die Lieder Deutsch lernen. Der Unterricht mit Liedern ist so besonders erfolgreich, weil Deutsch-Lernende Lieder überhaupt sehr gern haben, und auch weil sie beim Deutsch-Lernen durch Lieder besonders intensiv deutsche Landeskunde und deutsche Kultur kennenlernen können. Mit Einführung der DVD, der “Digital Versatile Disk” in den Bereich der Bildungsmedien wird Lehrenden und Lernenden eine bisher nicht gekannte Möglichkeit des Medieneinsatzes im Unterricht angeboten. Die DVD ist das Speichermedium der Zukunft. Sie ist so einfach zu handhaben wie eine herkommliche CD, verfügt über eine beeindruckende Speicherkapazitität und profitiert von einer hohen Datensicherheit. Ob als Träger fur Videos oder Musik in beachtlicher Qualität, als Backup- und Archivmedium oder zur Darbietung interaktiver Multimedia-Inhalte - kaum ein Medium erscheint dazu besser geeignet als die DVD. Das neue Medium DVD bietet neue Chancen für den Unterricht aller Fächer. Echte Interaktivität, das Zusammenführen von Video- und Tonsequenzen sowie Texten, Grafiken und Software machen die DVD zu einem didaktischen Medium. Ein guter, interessanter und abwechslungsreicher Unterricht, in dem die Lernende dem Lehrenden ihre Aufmerksamkeit widmen, ist heute von enormer Bedeutung. Nichts ist schlimmer als ein langweiliger, unvorbereiteter und monotoner Unterricht, der keiner der beiden Seiten einen Fortschritt bringt. Ein Unterricht ohne jeglichen Medieneinsatz ist heute nicht mehr vorstellbar.

( Soonam Yoo ),( Changhoon Lee ),( Beom Seob Lee ),( Young Tae Yun ) 한국농업기계학회 2018 바이오시스템공학 Vol.43 No.4

Purpose: The aim of this study was to investigate the harvesting performance of a prototype small combine for buckwheat and adlay. Methods: The prototype small combine was designed and constructed. Its ratio of grain loss, ratio of output components in the grain outlet, and field capacity for harvesting buckwheat and adlay were analyzed through field tests. Results: The prototype small combine required a working width of about 0.6 to 0.7 m to harvest buckwheat. The maximum travel speed was about 0.36 m/. The total ratio of grain loss was about 21.6%, which consisted of 8.8% at the header and 12.8% at the dust outlet. The grain and the material other than grain (MOG) ratios at the grain outlet were 94.1% and 5.9% respectively. In the case of adlay harvest, the maximum working width was about 1.2 m, that is, two rows. The range of maximum travel speed was about 0.45 to 0.46 m/s. When adlay was harvested in one row, the total ratio of grain loss ranged from 36.3 to 42.8% according to the cutting height. The cutting height of 30 cm resulted in a higher total ratio of grain loss than 60 cm and 90 cm. When the cutting height was 60 cm, there was no significant change in the total ratio of grain loss according to the number of working rows and the stage of the primary transmission shift. The total ratio of grain loss ranged from 35.2 to 37.7%. The grain and the MOG ratios at the grain outlet ranged from 93.1 to 95.8% and from 4.2 to 6.9%, respectively. No significant difference was observed in relation to cutting height, number of working rows, and the stage of the primary transmission shift. Conclusions: The prototype small combine for harvesting miscellaneous cereal crops showed good potential for the efficient harvesting of buckwheat and adlay. However, to improve the harvesting performance, there seems to be a need to develop new crop varieties suitable for machine-based harvesting and improve the transmissions, reels, separation/cleaning systems.

An Adaptive Threshold Technique for Fast PN Code Acquisition in DS-SS Systems

Soonam Yeom,Yunho Jung,Seongjoo Lee IEEE 2011 IEEE Transactions on Vehicular Technology VT Vol.60 No.6

<P>This paper presents an efficient technique to considerably reduce pseudonoise (PN) code acquisition time by adjusting threshold values, depending on the pre-estimated correlation energy in direct-sequence spread spectrum (DS-SS) systems. The proposed technique utilizing a threshold generation mode (TM) prior to a search mode is employed to a conventional double-dwell serial-search algorithm, and the TM determines the threshold values of both search and verification modes, depending on its correlation energy. We present a mathematical model of the proposed scheme to analyze it with respect to the mean code acquisition time in synchronous code-division multiple-access (CDMA) systems such as Third-Generation Partnership Project 2 (3GPP2) under a Rayleigh-fading channel. Numerical results show that the proposed method can reduce the mean code acquisition time by more than 60% and compensate for the performance degradation in high signal-to-noise ratios (SNRs) with no increase in hardware costs, compared with the conventional algorithm that adopts a soft-decision technique.</P>

염수남(Soonam Yeom),이성주(Seongjoo Lee) 大韓電子工學會 2011 電子工學會論文誌-TC (Telecommunications) Vol.48 No.6

본 논문은 직접 대역 확산(Direct sequence spread spectrum : DS-SS) 시스템에서 적응형 임계값을 적용하여 초기 동기 성능을 향상 시키는 알고리즘을 제안한다. 제안된 알고리즘은 탐색 모드(search mode) 이전에 프리덤프 모드(pre-dump mode)를 추가하고, 상관 에너지를 이용해 탐색 모드와 확인 모드(verification mode)의 임계값을 결정한다. 이를 통해 확인 모드뿐만 아니라 탐색 모드에서까지 거부 성능(rejection performance)을 향상시킬 수 있다. 제안된 방법은 기존 기술과 비교할 때 하드웨어 증가 없이 평균 코드 획득 시간(mean code acquisition time)을 약 40% 단축시킬 수 있다. This paper presents an efficient technique to reduce PN code acquisition time considerably by adjusting threshold values in direct sequence spread spectrum (DS-SS) systems. The proposed algorithm employs a pre-dump mode prior to a search mode, and the pre-dump mode determines threshold values of both search and verification modes depending on its correlation energy, which can improve not only the rejection performance of false code phases in the search mode but also that in the verification mode. The proposed method can reduce the mean code acquisition time by about 40% without increase of hardware costs compared with the conventional technique.

미혼남성의 라이프스타일 유형이 뷰티행동인식에 미치는 영향

홍수남 ( Soonam Hong ) 한국기초조형학회 2013 기초조형학연구 Vol.14 No.6

현대사회는 산업발달로 인한 경제적인 질적 향상, 결혼형태와 주거형태의 변화에 따라 다양한 라이프스타일을 지향하고 있다. 라이프스타일은 일반적인 인간 행동의 본질을 묘사로 하는 중요한 사회적 지표로 사용되는 용어로서 개인적인 시간의 활용, 주위환경의 중요성, 자신과 주위환경과의 관계에 대해서 인지하는 총체적인 삶의 방식을 의미한다. 최근 남성의 외모 가꾸기에 대한 인식이 보편화·다양화되면서 남성외모관리 유형을라이프스타일과 접목하여 연구를 진행하였고, 연구결과는 다음과 같다. 라이프스타일 유형은 자기계발, 경제실용, 과시소비, 외모지향의 4가지 요인으로 분류하였고, 뷰티행동인식은 메이크업과 헤어, 미용성형, 피부체형관리의 3가지로 구분하였다. 뷰티행동인식과 라이프스타일과의 상관관계를 알아본 결과 모든 뷰티행동인식은 라이프스타일과 정의 상관을 나타냈고, 라이프스타일의 모든 요인도 뷰티행동인식의 모든 요인과 정의 상관을 나타내어 뷰티행동인식은 라이프스타일과 밀접한 관계가 있음을 의미한다. 또한 라이프스타일 유형이 뷰티행동인식에 미치는 영향에 대해서 알아본 결과 경제실용, 과시소비, 외모지향의 순으로 나타났다. 이는 남성외모관리 및 뷰티행동인식은 아직까지는 여성보다 보편화·객관화 되지 않았으며, 이는 조사대상자의 인구통계학적인 차이도 있을 것이라고 보여진다. 결론적으로 본 연구의 미혼남성의 라이프스타일 유형이 뷰티행동인식에 미치는 영향을 알아본 결과 유행추구와 과시소비보다는 경제실용을 지향한다는 것을 알 수 있었으며, 이는 인구통계학적인 특성의 차이와 경제적 질적 향상과 패션·뷰티의 트렌드가 변화됨에 따라 달라질 수 있음을 의미한다. Considering that in modern days the perspective of men grooming their appearance is becoming prevalent, the beauty behavior consciousness according to men lifestyle was analyzed. This study`s result is as follows:First, lifestyle was categorized into four variables ?self-development, practical economy, ostentation consumption, and appearance orientation. Beauty behavior consciousness was categorized into three variables ? makeup and hair, cosmetic surgery, and skin/body care. Second, self-development`s average number was 3.04, with lifestyle the highest score, while for the beauty behavior consciousness had skin/body care as the highest, with the average of 3.07. Third, beauty behavior consciousness had well defined correlation with all lifestyle sub factors, while all the sub factors of beauty behavior consciousness had well defined correlation with lifestyle also. Fourth, the analysis of the effect of lifestyle category on the beauty behavior consciousness resulted in the order of practical economy, ostentation consumption, and appearance orientation. Thus we could see that the beauty behavior consciousness is positively proportional to practical economy, ostentation consumption, and appearance orientation.

Prediction of Labor Requirement and Cost of Pick-up Type Pulse Crop Harvester for Soybean and Red Bean Harvesting

Yoo, Soonam,Chang, Heesoo Korean Society for Agricultural Machinery 2014 바이오시스템공학 Vol.39 No.4

Purpose: This study was carried out to evaluate the labor requirement and the cost-reducing effects of the pick-up type pulse crop harvester compared with those of conventional harvesting for soybeans and red beans. Methods: The labor requirement and the cost to gather, thresh, and clean for conventional harvesting operations were surveyed; those for the pick-up type pulse crop harvester were estimated for soybeans and red beans. The annual capacity of the harvester and the break-even area of the two harvesting methods were also estimated. Results: For soybean harvesting, the labor requirement of 0.57 hour-persons/10 a for the pick-up type pulse crop harvester reflects a 91.9% reduction in the labor requirement of 7.00 hour-persons/10 a for conventional harvesting. Machinery costs of 51,300 won/10 a for the harvester were estimated for an annual harvesting area of 52.5 ha/year, representing a reduction of 33.3% from the 78,700 won/10 a cost of conventional harvesting. A break-even area of 28.4 ha was estimated for the two harvestings. For red bean harvesting, the labor requirement of 0.57 hour-persons/10 a for the harvester reflects a 92.6% reduction in the labor requirement of 7.66 hour-persons/10 a for conventional harvesting. For an annual harvesting area of 52.5 ha/year, annual capacity of 52.5 ha/year and machinery costs of 51,700 won/10 a were estimated for the harvester, reflecting a reduction of 44.7% in the cost of 93,500 won/10 a for conventional harvesting. A break-even area of 23.1 ha was estimated for the two harvestings. A governmental subsidy for purchasing the harvester could contribute to reducing the break-even area and harvesting costs. Conclusions: The pick-up type pulse crop harvester for soybean and red bean harvesting could reduce the labor requirement and costs of conventional harvesting, and a governmental subsidy for purchasing the harvester will improve the economics of the harvester for efficient mechanical harvesting.

GFSK 시스템에서 심볼 타이밍 추적 회로 설계

염수남(SooNam Yeom),이성주(Seongjoo Lee) 대한전기학회 2010 대한전기학회 학술대회 논문집 Vol.2010 No.7

가우시안 주파수 편이 통신에 있어서, 주파수 오차와 샘플링 오차에 따른 채널 영향으로 심볼 주기가 샘플 수와 일치되지 않는다. 샘플링 오차는 시간이 지날수록 심해져서 심볼에 대한 복조 오류를 불러일으킨다. 따라서 본 논문에서는 심볼 타이밍 추적 회로를 통해 샘플링 오차에 대한 문제를 해결할 수 있는 알고리즘을 제안하고, 이를 통해 BER 성능을 크게 향상시켰다. 본 논문의 알고리즘은 FPGA 보드에서 SPI통신 방법으로 소프트웨어와 연동해 검증되었고, 현재 Silterra 0.18㎛ 공정에서 아날로그 SoC로 구현되어 칩 레벨에서 검증을 진행하고 있다.
