  • In this paper, we study a FDS(fishery detection system) for protection of an aquaculture farm. The FDS will identify a robbing vessel with real time and detect variance of the position of aquaculture farm. We also propose a F-AIS(Fishery- Automatic Identification System), which can detect the object approaching to aquaculture farm and distinguish fishing boats from thief vessel The F-AIS with low price and wideband responsibility will be adopted to the FDS.

  • Das Ziel dieser Arbeit ist es, als eine methodische Grundlage zur Erstellung des koreanisch-deutschen WordNets das Grundwissen $\"{u}ber$ das WordNet und einige bisherige Untersuchungen des WordNets darzulegen. Ais erster Schritt wurde einige grundlegende Punkte $f\"{u}r$ das WordNet im Rahmen des WordNets fur Englisch in Betracht gebracht. Dabei ging es um lexikalische Hierarchie, und um semantische Relationen zwischen den Synsets(Zusammensetzen der synonymen $W\"{o}rter$) wie Synonymy, Antonymy, Hyponymy, Mronymy, Troponomy und Entailment. $Anschlie{\ss}end$ wurden EuroNet und GermaNet in kurzer Form vorgestellt, die auf dem Princeton WordNet basierten. EuroNet ist eine multilinguale Datenbasis mit WordNets $f\"{u}r$ einige europaische Sprachen (hollandisch, italienisch, spanisch, deutsch, franzasisch, tschechisch und estnisch). Dieses auf das Deutsch bezogenen WordNet kann wichtige Hinweise $f\"{u}r$ die Erstellung des koreanisch-deutschen WordNets geben. In Korea wurden auch verschiedene Untersuchungen uber das WordNet $f\"{u}r$ Koreanisch unternommen. Darunter kann insbesondere KORTERM WordNet $f\"f{u}r$ Koreanisch als ein umfassendes System $erw\"{a}hnt$ werden, in dem Nomen, Verben, Adjektive und Adverbien miteinander interagieren. KORTERM WordNet fur Koreanisch ist eine multilinguale Datenbasis mit WordNets $f\"{u}r$ einige asiatische Sprachen (koreanisch, japanisch und chinesisch) und versucht noch die weiteren Sprachen in diese multilinguale Datenbasis hineinzubringen. Nach diesem WordNet wird das koreanisch-deutsche WordNet erstellt.

  • Objective: To investigate the relationship between 18F-FDG PET/CT semi-quantitative parameters and the International Association for the Study of Lung Cancer, American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) histopathologic classification, including histological subtypes, proliferation activity, and somatic mutations. Materials and Methods: This retrospective study included 419 patients (150 males, 269 females; median age, 59.0 years; age range, 23.0-84.0 years) who had undergone surgical removal of stage IA-IIIA lung adenocarcinoma and had preoperative PET/CT data of lung tumors. The maximum standardized uptake values (SUVmax), background-subtracted volume (BSV), and background-subtracted lesion activity (BSL) derived from PET/CT were measured. The IASLC/ATS/ERS subtypes, Ki67 score, and epidermal growth factor/anaplastic lymphoma kinase (EGFR/ALK) mutation status were evaluated. The PET/CT semi-quantitative parameters were compared between the tumor subtypes using the Mann-Whitney U test or the Kruskal-Wallis test. The optimum cutoff values of the PET/CT semi-quantitative parameters for distinguishing the IASLC/ATS/ERS subtypes were calculated using receiver operating characteristic curve analysis. The correlation between the PET/CT semi-quantitative parameters and pathological parameters was analyzed using Spearman's correlation. Statistical significance was set at p < 0.05. Results: SUVmax, BSV, and BSL values were significantly higher in invasive adenocarcinoma (IA) than in minimally IA (MIA), and the values were higher in MIA than in adenocarcinoma in situ (AIS) (all p < 0.05). Remarkably, an SUVmax of 0.90 and a BSL of 3.62 were shown to be the optimal cutoff values for differentiating MIA from AIS, manifesting as pure ground-glass nodules with 100% sensitivity and specificity. Metabolic-volumetric parameters (BSV and BSL) were better potential independent factors than metabolic parameters (SUVmax) in differentiating growth patterns. SUVmax and BSL, rather than BSV, were strongly or moderately correlated with Ki67 in most subtypes, except for the micropapillary and solid predominant groups. PET/CT parameters were not correlated with EGFR/ALK mutation status. Conclusion: As noninvasive surrogates, preoperative PET/CT semi-quantitative parameters could imply IASLC/ATS/ERS subtypes and Ki67 index and thus may contribute to improved management of precise surgery and postoperative adjuvant therapy.

  • Die $W\"{o}rterb\"{u}cher$ spielen beim Erwerb einer Sprache eine wesentliche Rolle. Es gibt inzwischen mehrere Deutsch-Koreanische $W\"{o}rterb\"{u}cher$. Die Lage $f\"{u}r$ die Koreanisch-Deutschen $W\"{o}rterb\"{u}cher$ ist aber verbesserungs- $bed\"{u}rftig$. Stellvertretend $f\"{u}r$ das Koreanisch/Deutsche $W\"{o}rterbuch$ steht das 1981 von der Koreanischen Gesellschaft $f\"{u}r$ Germanistik nach $zehnj\"{a}hriger$ Arbeit fertiggestellte Essence Koreanisch-Deutsche $W\"{o}rterb\"{u}ch$ (Minjung seorim 1982). Dieses $W\"{o}rterb\"{u}ch$ weist aber einige Nachteilen auf. Es fehlen jegliche Angaben zum Korpus. Man $st\"{o}{\ss}t$ beispielsweise oft auf selten gebrauchte $W\"{o}rter$, die Grundbedeutungen sind nicht erkennbar, die Erklarungen sind ungenau, manchmal sogar $irref\"{u}hrend\;und\;schlie{\ss}lich$ mitunter stilistisch falsch. Diese negativen Punkte wirken sich $ung\"{u}nstig$ auf den gesamten Lemprozess bis hin zur Lemmotivation aus. Aus diesen Gegebenheiten $erw\"{a}chst$ die Notwendigkeit der Erstellung eines neuen $W\"{o}rterb\"{u}ch$s, das auf die Situation von Sprachlemem abgestimmt ist, die zur Benutzung einsprachiger $W\"{o}rterbticher$ noch nicht imstande sind. Zweck des $W\"{o}rterb\"{u}chs$ ist der Einsatz im Fremdsprachenunterricht, woraus sich ein zweisprachiges $W\"{o}rterb\"{u}ch$ ergibt. Als Benutzerkreis werden insbesondere $Sprachlemanf\"{a}nger$ des Koreanischen und Deutschen ins Auge gefasst. Ihnen soll ein Nachschlagewerk an die Hand gegeben werden, das den koreanischen und deutschen Wortschatz anhand einer Systematik und eines alphabetischen Indexes der jeweiligen Sprache $erschlie{\ss}t$. Ais Zahl der Lemmata wird $f\"{u}r$ jede Sprache ca. 10,000 festgelegt. Ein Grundwortschatz, der die 3000 $h\"{a}ufigsten\;W\"{o}rter$ umfasst wird extra markiert. $Dar\"{u}ber$ hinaus bietet das $W\"{o}rterb\"{u}ch$ den darauf aufbauende Wortschatz von weiteren 7000 $W\"{o}rtern$. Die Teamarbeit der beiden Gruppen von Muttersprachlern steht in allen Arbeitsschritten im Vordergrund. Der damit verbundene Zweck ist die Erzielung der maximalen Genauigkeit der $Lemmaerkl\"{a}rungen$. Da dieses $W\"{o}rterb\"{u}ch$ ein $W\"{o}rterb\"{u}ch$ nach Sachgruppen ist, die Erstellung einer Systematik von $gro{\ss}er$ Bedeutung. $F\"{u}r$ das vorliegende Projekt gait daher eine Systematik zu finden, die nicht nur leicht nachvollziehbar, also praktikabel ist, sondern insbesondere von Benutzern aus zwei Kulturkreisen akzeptiert werden kann. Als $grunds\"{a}tzliche$, allerdings nicht in allen Bereichen $gleicherma{\ss}en$ anwendbare Ordnungsprinzipien gelten: Vom Oberbegriff zum Unterbegriff, vom allgemein zum speziell, vom Einfach zum Komplexen, von $au{\ss}en$ nach innen, Darin spiegelt sich das Prinzip der 'notwendigen Bedingung' wider.
