Modalpartikeln, die auch $Abt\"{o}nungspartikeln,\;W\"{u}rzw\"{o}rter,\;F\"{a}rbew\"{o}rter$ usw. genannt werden, galten eine Zeitlang als $\"{U}berfl\"{u}ssiges$. Aber mit der 'kommunikativ­pragrnatischen Wende' hat die Partikelforschung einen enormen Aufschwung genommen. Auch im Femdsprachenunterricht waren Partikeln als etwas Unwichtiges oder in anderen Worten etwas schwer zu Behandelndes geblieben und wurden deshalb zur Seite geschoben. Mit Hilfe der Aufschwung der Partikelforschung in Deutschland untersuchte ich koreanische $\"{U}bersetzungsm\"{o}glichkeiten$ von Modalparikeln. Ich $\"{u}bernahm$ Diewaldische Methode. Sie $schl\"{a}gt$ ein Beschreibungsschema vor: Modalpartikeln haben verweisende und $verkn\"{u}fende$ Funktion. Sie weisen $n\"{a}hmlich$ auf den pragmatischen $Pr\"{a}text\;zur\"{u}ck$ und bringen ihn in relevanter Situation mit der Modalpartikel enthaltenden $\"{A}u{\ss}erung$ in Beziehung. Da braucht man also drei Ebenen: pragmatischer $Pr\"{a}text$, relevante Situation und partikelhaltige $Au{\ss}erung$. Die Schwierigkeit der $\"{U}bersetzungsm\"{o}glichkeiten$ von Modalkartikeln besteht darin, jeweiligen $Pr\"{a}text$ und jeweilige relevante Situation wiederherzustellen und auszudrticken. In diesem Aufsatz geht es nur um 'doch'. 'doch' ist eine der $h\"{a}ufigsten$ Modalpartikeln und tritt in vielen verschidenen Satzarten. 'doch' tritt in Aussage-, Imperativ-, Ausrufe­und Wunschsatzen auf. $Au{\ss}erdem$ tritt 'doch' in $Erg\"{a}nzungsfragen$ und Entscheidungsfragen mit Intonation auf und ist aber nur bei 'echten' Fragen ausgeschlossen. Aus der diachronischen Bedeutungsentwicklung und dem Bedeutungsvergleich zu ihren Homonymen stellten sich die semantischen Merkmale von 'doch' als $Adversativit\"{a}t\;und\;Konzessivit\"{a}t$. Aber diese semantischen Komponenten werden bei dem Modalpartikel $abgeschw\"{a}cht$ und pragmatische Faktoren werden in verschiedenen $Verwendungsm\"{o}glichkeiten$ verstarkt. Unter $Ber\"{u}cksichtigung\;jeweiligen\;Pr\"{a}textes$ und relevanter Situation schlug ich koreanische $\"{U}bersetzungsm\"{o}glichkeiten$ von 'doch' je nach der Satzart und nach der $Verwendungsm\"{o}glichkeit$ vor.

The general pharmacological properties of EPO were investigated in various animals administering intravenously and in vitro system. The results were as follows. 1. Central nervous system: EPO at doses of 70, 700, 7000 U/kg showed no effect In mice on general behavior, on strychnine- and pentetrazol-induced convulsion and on acetic acid-induced writhing syndrome. The hexobarbital-induced sleeping time in mice was slightly reduced by EPO at a dose of 7000 U/kg but did not change at doses of 70, 700 U/kg. The body temperature in rats was slightly decreased by EPO at doses of 700, 7,000 U/kg but the change was in normal physiological range. 2. Respiratory and cardiovascular system: EPO showed no effect on respiratory rate, blood pressure, heart rate, femoral blood flow, and electrocardiogram in anesthetized dogs at doses of 70, 700, 7000 U/kg. 3. Smooth muscle: EPO at concentrations of 70, 700 U/ml had no effect on the contractile response of isolated guinea pig ileum to histamine and acetylcholine. 4. Water and electrolytes excretion: EPO at dose above 700 U/kg increased urine volume in rats but did not affect the concentrations of $Na^{+},\;K^{+},\;Cl^{-}$ in urine. 5. Gastrointestinal system: EPO(70, 700, 7000 U/kg) had no effect on the intestinal charcoal meal propulsion 6. Blood coagulation system: The administration of EPO(70, 700, 7000 U/kg) had no effect on the plasma prothrombin time(PT) and activated partial thromboplastin time(APTT) in mice. Platelet aggregation induced by ADP and collagen was not influenced by EPO(70 U/ml, 700 U/ml). The overall results obtained indicated that EPO exerts almost no serious pharmacological effect even at a 100-fold clinical dose(7000 U/kg).

A large scale field test of prefabricated vertical drains is performed to analyze the effect of parameters of the very soft clay at a test site. Compression index and the coefficient of horizontal consolidation obtained by back-analysis from the settlement data were compared with those obtained by means of laboratory tests. The Hyperbolic, Asaoka's and The Curve fitting methods are used to estimate final settlements and coefficients of consolidation. 1. Final settlement predicted with the Hyperbolic method was the largest, and the settlements predicted with the Asaoka's and the Curve fitting methods were nearly the same range, and it was concluded that smear effect has to be considered on design in the case that spacing of drains is small 2. The relationships of the measured consolidation ratio (Urn) and the designed consolidation ratio($U_t$) were showed as $U_m$ = (1.13~1.17)$U_t$, $U_m$ = (1.07~1.20)$U_t$, $U_m$ = (1.13~1.17)$U_t$ on the Hyperbolic, Asaoka's and the Curve fitting methods, respectively. The relations on the Asaoka's and the Curve fitting methods were nearly the same range. 3. The relationships of the field compression index($C_{cfield}$) and virgin compression index($V_{cclab}$) were showed as $C_{cfield}$ = (1.26~1.45)$V_{cclab}$, $C_{cfield}$ = (1.08~1.15) $V_{cclab}$, $C_{cfield}$ = (1.04~1.21)$V_{cclab}$, on the Hyperbolic, Asaoka's and the Curve fitting methods, respectively. 4. The ratio ($C_h/C_v$) of the coefficient of vertical consolidation and the coefficient of horizontal consolidation that is obtained by back-analysis from the settlement data was $C_h$=(0.7~0.9)$C_v$, $C_h$=(0.9~1.5)$C_v$, $C_h$=(2.4~3.0)$C_v$ on the Hyperbolic, Asaoka's and the Curve fitting methods, respectively. 5. It was concluded that the exact consolidation coefficient must be determined after the final settlement is predicted again when the consolidation is finished, because the field consolidation coefficient is decreased as the time allowed to be alone is increased.

Background: Radioactive iodine (RAI) therapy and whole-body scanning are the fundamentals of treatment and follow-up of patients with differentiated thyroid cancer. It is generally accepted that a Thyroid-Stimulating Hormone (TSH) level of at least 30 ${\mu}U/ml$ is a prerequisite for the effective use of RAI, and that it requires 4-6 weeks of off-thyroxine to attain these levels. Because thyroxine withdrawal and the consequent hypothyroidism are often poorly tolerated, and occasionally might be hazardous, it is important to be certain that these assumptions are correct. We have measured serial changes in serum TSH after total thyroidectomy or withdrawl of thyroxine in patients with thyroid cancer. Subjects and Methods: Serum TSH levels were measured weekly after thyroidectomy in 10 patients (group A) and after the discontinuation of thyroxine in 12 patients (group B). Symptoms and signs of hypothyroidism were also evaluated weekly by modified Billewicz diagnostic index. Results: By the second week, 78% of group A patients and 17% of group B patients had serum TSH levels ${\geq}30{\mu}U/ml$. By the third week, 89% of group A patients and 90% of group B patients had serum TSH levels ${\geq}30{\mu}U/ml$. By the fourth week, all patients in two groups achieved target TSH levels and there were no overt hypothyroidism. Conclusion: in all patients, serum TSH elevated to the target concentration (${\geq}30{\mu}U/ml$) within 4 weeks without significant manifestation of hypothyroidism. The schedule of RAI administration could be adjusted to fit the needs and circumstances of individual patients with a shorter preparation period than the conventional.

A recent major development in computer technology is the advent of the wearable computer system that is based on human-centric interface technology trends and ubiquitous computing environments. Wearable computer systems can use the wireless universal serial bus (WUSB) that refers to USB technology that is merged with WiMedia PHY/MAC technical specifications. In this paper, we focus on an integrated system of the wireless USB over the IEEE 802.15.6 wireless body area networks (WBAN) for wireless wearable computer systems supporting U-health services. And a communication structure that can differentiate QoS of U-health WBAN and WUSB traffic with different priorities is proposed for WUSB over IEEE 802.15.6 hierarchical protocol. In our proposal and performance evaluation, throughputs of U-health WBAN and WUSB traffic are analyzed under single and multiple QoS classes to evaluate the effectiveness of proposed QoS differentiating structure in WUSB over IEEE 802.15.6.

The purpose of this research is to design and develop an evaluation system with a view to improving teaching skills in the u-Campus environment. To achieve the purpose, this research analyzed various theories on the effectiveness of teaching and teaching evaluation system, extracting several evaluation factors which are to be included in the system. Based on these evaluation factors, this research developed a prototype by reflecting teaching assessment, coaching, self-reflection, portfolio, supervisor selection, user authority in sharing the portfolio and ubiquitous technology. This prototype differs from the existing evaluation methods in that it can enlarge the extent of supervisors other than professors according to their own selecting and can reduce the burden of assessment task, thus improve their teaching skills. This teaching evaluation system using portfolio and ubiquitous technology will be an innovative alternative to conventional assessment methods and will be of great help to qualitative progress in higher level education.

This is a follow-up study on Han and Kang (2013) which argued that the Euclidean distances between /o/ and /u/ in Seoul Korean decreased in the first syllable position as speakers were among younger female speakers but not for male speakers, whereas in the second syllable position both gender groups showed a cross-generational decreasing effect of the Euclidean distance between /o/ and /u/. This study normalized the same data in Han and Kang (2013) which measured 12 speakers (six males and six females) for each Age group and investigated the spectral changes vowels /o/ and /u/ between age and gender, using the log-mean normalized statistical results. This study also examined overlap fraction values generated in SOAM 2D ($F1{\times}F2$) (cf. Wassink, 2006), which may also indicate the proximity of two vowels in question. The results showed that /o/ and /u/ vowels were making closer with /o/ raising for female speakers in $V_1$ and $V_2$ positions but only in the $V_2$ position for male speakers. That is, females led the upward movement of peripheral /o/ vowel, just like the raising of 'e' and 'o' in New York City (Labov, 1991). The results also showed that younger speakers used a rather narrow vowel space for the vowels. This also contributed to the proximity of the vowels /o/ and /u/, resulting in rather large overlap fraction values for younger speakers between these two vowels.

Objectives : We are aimed to identify anti-tumor effects of realgar on some kinds of cancer cells through molecular biologic methods. Materials & Methods : We used 5 kinds of cancer cell lines: lung cancer cells(A549). stomach cancer cells(KATO) and neuroglioma cells(SUN-1118. U-87MG, U-373MG). We injected the boiled extracts of realgar $50{\mu}g$. $100{\mu}g$ to cultural media( ml )for 24 hours. We measured the killing effects on 5 kinds of cancer cells through inverted and fluorescence microscope, the suppressive effects on viability of those cells via XTT assay and the effects on the revelation of Bax and Bcl-2 proteins related to apoptosis by western blotting. Results : In the changes of morphology, the extracts of realgar showed more significant killing effects on all cancer cells. especially KATO, SNU-1118, U-87MG, U-373MG, than the control group with dose dependence, which was statistically significant. In XTT assay, the extracts of realgar showed more suppressive effects on viability of all cancer cells, especially KATO and U-373MG, than the control group with dose dependence, which was statistically significant. In the revelation of proteins related to apoptosis, the extracts of realgar increased the level of Bax and decreased that of Bcl-2 in all cancer cells with dose dependence. Conclusions : We identified that realgar had more anti-tumor effects on stomach cancer and neuroglioma than on lung cancer in the experiments above. However, these basic experiments were performed in vitro. We hope the anti-tumor effects of realgar will be practically identified through more progressive research.
