In dieser Abhandlung wurde im Bereich der $Temporalit\"{a}t$ anhand des konzeptorientierten Ansatzes das $Verh\"{a}ltnis$ yon konzeptueller und sprachlicher $Repr\"{a}sentation$ betrachtet. Die $Temporalit\"{a}t$ ist ein abgeleiteter Begriff, den das menschliche$Bewu{\ss}tsein$ im Rahmen seiner kognitiven Entwicklung als $Ma{\ss}stab$ der qualitativen $Ver\"{a}nderung$ und Bewegung von Materie warhnimmt und systematisch konzeptualisiert. Ihre Subkategorien unterscheiden sich in den Sprachen, da bei den $Konzeptualisierungsvorg\"{a}ngen$ durch die Muttersprache bestimmte begriffliche Kategorien eine steuernde Rolle spielen. In diesem theoretischen Hintergrund betrachteten wir, inwieweit die beiden Sprachen, das Deutsche und das Koreanische, im Bereich des Zeitkonzepts auf der konzeptuellen Ebene und auf der Ausdrucksebene verschieden und gemeinsam sind, und wie das $Verh\"{a}ltnis$ zwischen den temporalen Konzepten und den $Ausdrucksm\"{o}glichkeiten$ ist. Die $Temporalit\"{a}t$ des Koreanischen ist in Bezug auf die Basiskategorien der $Temporalit\"{a}t$ mit dem Deutschen mehr oder weniger identisch. Zum Ausdruck der Zeitreferenz haben die beiden Sprachen gemeinsam zwei explizite grammatische und lexikalische $Ausdrucksm\"{o}glichkeiten$, aber die Art und Weise, wie sie zum Ausdruck der Subkategorien der $Temporalit\"{a}t$ eingesetzt werden, sind verschieden. In diesem Zusammenhang kann man sagen, $\dabeta$ es zum Verstandnis der $\dabeta$ in der Sprache nicht reicht, die sprachliche Formen zu betrachten: man $mu\ss$ die Konzepte berucksichten, die durch die sprachlichen Formen $ausgedr\"{u}ckt$ werden.

Bioassay data analysis software (BiDAS-2007) has been developed by KAERI, which adds several new functions to its previous version. New functions of the BiDAS-2007 computer code enable the user not only to do a simultaneous analysis by using two or more types of bioassay for the best internal dose evaluation, but also to do a continual internal dose evaluation from a change of the internal exposure conditions such as an intake type (acute, chronic), an intake pathway (inhalation, ingestion), an absorption type (Type F, M, S), and a particle size (AMAD, activity median aerodynamic diameter), and also to estimate the intakes in various conditions of an internal exposure at a time. The values calculated by the BiDAS-2007 code are consistent and in good agreement with those values by IMIE-2004 code by Berkovski and IMBA code by Birchall. The BiDAS-2007 computer code is very useful and user-friendly to estimate the radionuclide intakes and committed effective doses of a radiation worker.

This study presents a novel monitoring technique for underwater high-voltage direct current (HVDC) cables based on the Distributed Acoustic Sensor (DAS). The proposed technique utilizes vibration and acoustic signals generated on HVDC cables to monitor their condition and detect events such as earthquakes, shipments, tidal currents, and construction activities. To implement the monitoring system, a DAS based on phase-sensitive optical time-domain reflectometry (Φ-OTDR) system was designed, fabricated, and validated for performance. For the HVDC cable monitoring experiments, a testbed was constructed on land, mimicking the cable burial method and protective equipment used underwater. Defined various scenarios that could cause cable damage and conducted experiments accordingly. The developed DAS system achieved a maximum measurement distance of 50 km, a distance measurement interval of 2 m, and a measurement repetition rate of 1 kHz. Extensive experiments conducted on HVDC cables and protective facilities demonstrated the practical potential of the DAS system for monitoring underwater and underground areas.

The aim of this study was to investigate the amounts of glucosinolates (GSL) in kale at various development stages. Kale varieties 'Manchoo Collard' and 'TBC' were cultivated from 20 February 2012 to 3 July 2013 in the greenhouse at Chungnam National University. During the cultivation periods, samples were harvested at 35, 63, 91, 105, 119, and 133 days after sowing (DAS) and the amount of GSL quantified by HPLC. Ten types of GSL (progoitrin, sinigrin, glucoalyssin, gluconapin, glucoiberverin, 4-hydroxyglucobrassicin, glucobrassicin, 4-methoxyglucobrassicin, gluconasturtiin, and neoglucobrassicin) were observed in 'TBC', whereas nine types of GSL (the same as above, except glucoiberverin) were identified in 'Manchoo Collard'. The amount of total GSL in 'Manchoo Collard' was comparatively higher at 133 DAS (mean $8.64{\mu}mol{\cdot}g^{-1}$) and lower at 35 DAS ($1.16{\mu}mol{\cdot}g^{-1}$ dry weight, DW) of cultivation. In the case of 'TBC', the amount of GSL was higher at 91 DAS (mean $13.41{\mu}mol{\cdot}g^{-1}$) and lower at 35 DAS ($0.31{\mu}mol{\cdot}g^{-1}$ dry weight, DW). Sinigrin was the most abundant GSL (57% of total GSL) in 'Manchoo Collard' at 133 DAS and was also highest (44%) in 'TBC' at 91 DAS. Together, progoitrin, sinigrin, glucobrassicin, and gluconasturtiin, the precursor of crambene, allylisothiocyanate, indol-3-cabinol, and phenethylisothiocyanate accounted for 94 and 78% of GSL in 'Manchoo Collard' and 'TBC', respectively. Our results demonstrate that the amounts of GSL, which have potential anti-carcinogenic activity, change during development in kale.

In Response Surface Methodology (RSM), rotatability is a natural and highly desirable property. For second order general correlated regression model, the concept of robust rotatability was introduced by Das (1997). In this paper a new measure of robust rotatability for second order response surface designs with correlated errors is developed and illustrated with an example. A comparison is made between the newly developed measure with the previously suggested measure by Das (1999).

DAS(Distribution Automation System) is equipped with several software applications such as service restoration, loss minimization, and protective relay coordination. The software applications of DAS are very sensitive to the amount of section load being carried by a particular section of distribution lines. Moreover, each software application requires a different parameter of the section load according to its purpose. Therefore, This paper proposes a new section load management method using real-time measurement data of the distribution lines. In order to provide accurate data to DAS applications, this method considers section loads in terms of the relationship of power versus time. In order to establish that the proposed method is feasible, a performance-testing simulator was developed, and case studies were conducted for a modified real distribution network.
