The purpose of this study is to examine the implications of religious activities to longevity in a perspective of religious people in the ancient near east. The major sources of the study are the records of Adad-Guppi in the Neo-Babylonian Empire, prayers of Daniel in the Old Testament and records of Anna in the New Testament. The research method is a synchronic method based on final forms of the texts. Adad-Guppi lived for 104 years with temple-centered lives, fasting-like dedication, prayer and mission for the nation. Daniel fasted and prayed for the return of Jewish nation, and restoration of the city and the temple in Jerusalem, resulting in longevity of late eighties in the court of Babylon. Anna lived for more than 100 years old with her life mission for the messiah in spite of limitations of her times as an old widow. The implications of religious activities with temple-centered lives, fasting, prayer, and mission for the ages are understood to be beneficial to longevity in a perspective of the ancient near east.

The balance of power in conventional forces between the two Koreas works in favor of the South Korea in the Korea peninsula. But, the balancing mechanism between the two Koreas in asymmetric forces like nuclear and missile forces works absolutely in favor of the North Korea. That's why it should be timely for the ROK military to review existing strategy and revise a new counter strategy against the threat posed by the North Korea's nuclear and missile forces. The ROK military is now developing 4D, KAMD, KILL Chain strategies as means to cope with the North Korea's nuclear and missile threats. Considering efforts and resources invested now, the strategies are expected to be in place in next five or more years. However, approaches to those strategies seem to be rather fragmentary and conceptual than comprehensive and pragmatic. The types of strategies against the North Korea's military threats need to be a deterrence in peace time and a fighting and winning in war time in the Korean theater. But, the most important element in the deterrence strategy is the credibility. This study concludes with an new strategic concept titled "ADAD(Assured Defense, Assured Destruction)" as an alternative to existing strategies to deal with the North Korea's nuclear and missile threats.

A series of terpolymers based on stearyl methacrylate (SMA), n-methyol acrylamide (n-MAM), and 2-(perfluorooctyl) ethyl acrylate (PFOEA) were synthesized by changing PFOEA contents up to 8 wt% in order to obtain optimal water-repellent properties. In addition, various contents of m-isopropenyl-${\alpha}$,${\alpha}^{\prime}$-dimethylbenzyl isocyanate (TMI) from 1 to 4 wt% were added to the above terpolymers with 4 wt% of PFOEA content. The emulsion polymerization was carried out using tridecyl alcohol (EO)7 (TDA-7) as a nonionic surfactant, alkyl dimethyl amine derivatives (ADAD) as a cationic surfactant, and 2,2'-azobis(2-amidinopropane dihydrochoride) (AAPDL) as an initiator. The synthesized copolymers were characterized by FT-IR spectroscopies, contact angle, surface energy, and water-repellency. Surface and thermal properties were analyzed by SEM, TGA, and DSC. It was found that water repellency increased with increasing the contents of PFOEA and TMI.

To investigate the physical properties of sea tangle (Laminaria japonica) alginates, extracted by the Mexican process, the effects of extracting time and drying methods on intrinsic viscosities, MWs and DPs of alginates were examined. The MWs of alginates before and after dialysis decreased with increase of extracting time. The MW s before dialysis were lower than those after dialysis. The ash contents before dialysis decreased with increase of extracting time. After dialysis the ash contents of the alginates showed 10.4-10.9% of those, which were little affected by extracting time. In the ash composition after dialysis, the sodium content was 4.4 g/100 g, $90\%$ of total ash content. The ash contents, the intrinsic viscosities, the average molecular weight and the DPs of the alginates dried by AD before dialysis were higher than those by VF. The ash and uronic acid contents of alginates after dialysis showed $10.6-10.9\%\;and\l88.1-88.9\%$, respectively. But the intrinsic viscosities, the MWs and DPs of the alginates after dialysis gradually decreased by following dry methods. The decreased order was ADAD, ADVF, VFAD, VFVF. The coefficient of determination between MWs and DPs in the alginates having more than 300 kDa was 0.999.

The objective of this study was to investigate their physicochemical properties and antioxidant activities of white radish teas such as pH, color value, total polyphenol contents, total flavonoids, DPPH radical scavenging activity, reducing power and sensory evaluation. They were processed by drying(AD), drying and roasting(ADR), steaming and drying(SAD), and steaming, drying, and roasting(SADR). As a result, the pH of ADR, and SADR tended to be significantly lowered and SADR was the lowest at $5.48{\pm}0.14$(p<0.001). Additionally, ADR and SADR were significantly different in color and browning value, compared to AD and SAD. There was no significant difference in reducing sugar content depending on processing methods. The total polyphenol content and total flavonoid content of the teas were significantly increase after roasting. DPPH radical scavenging activity was significantly higher in ADR and SDAR than in AD or SAD by 1.1~1.5 times(p<0.05). Compared with ADR and SADR after roasting, the sensory characteristics of AD and SAD were significantly lower than those of roasted ADAD and SAD, respectively. From the above results, it was concluded that the roasting process is a major process that affects the physicochemical quality characteristics and antioxidant activities.
