미래전은 과학기술의 발달로 네트워크 기반의 정보작전이 중심이 되는 형태로 발전하게 되며, 정보작전에 운용되는 시스템을 무력화시키기 위한 방편으로 전자전 형태의 항법전이 더욱 대두 될 것으로 판단된다. 따라서 향후 미래전에 대비하기 위해 강대국들이 독자적인 GNSS 첨단위성항법시스템 구축을 위한 경쟁을 하고 있는 시점에서 최신 추진 동향을 분석하고, 현 구축단계를 점검함으로써 향후 우리의 나아가야 할 방향을 제시하고자 한다.

철강 플랜트 주요 설비인 전로를 지지하는 장치의 접합부 강도설계를 위해 작용하중은 해석적인 방법으로 신뢰성 있게 계산하였고, 정적하중에 의한 응력은 ASME 규정에 따른 허용응력으로 평가하였다. 한편 피로설계 측면에서는 전로와 같은 대형 용접구조물은 강도상 취약부인 용접부에서 다양한 용접비드 형상에 따라 국부응력이 크게 달라지므로 설계단계에서 피로수명 평가에 어려움이 있었다. 따라서 전로 지지장치 접합부 피로설계는 설계단계에서 피로수명을 평가하는 실용적이고 안전측 방법으로 알려진 Hot Spot 응력을 사용하고 공신력을 갖는 설계규정인 ASME와 영국 PD 5500 절차에 의해 평가하였다. 평가결과 두 규정 모두 안전측에서 평가되는 것을 확인할 수 있었고 이 방법은 피로하중이 지배적인 대형구조물의 설계단계에서 유용한 방법으로 활용할 수 있으리라 판단된다.

This research conducted a positive research to raise the effect of contest exhibitions as PR mechanism, considering the present condition increase in number of consumer participating in contest exhibitions and increase in organizations hosting such exhibitions. This research investigated whether there are differences in corporate image and behavior intention before and after the exhibition. Furthermore, it verified whether there are differences in behavior intention depending on level of satisfaction after exhibition. For the research, 139 university students from 7 universities nationwide who participated in exhibition hosted by public organizations were selected for analysis. The result shows that there are changes in corporate image and behavior intention before and after exhibitions. The corporate image depending on satisfaction level after exhibition shows that there are significant changes in professional image and trust image, but not in social contribution image. Based on the research result, we verified the value and effect of contest exhibitions.

This study is descriptive research to identify the effect of COVID-19 stress on premenstrual syndrome in female college students and the mediating effect of depression and coping with premenstrual syndrome. The data were collected through an on-line survey for 20 days from November 11 to November 30, 2021, targeting female college students attending C College located in S city. As a result of analyzing a total of 161 data, COVID-19 stress was positively correlated with premenstrual syndrome(r=.383, p<.001) and depression(r=.436, p<.001), and coping with premenstrual syndrome had a positive correlation only in premenstrual syndrome(r=.190, p=.016). As a result of verifying the mediating effect of depression and coping with premenstrual syndrome between COVID-19 stress and premenstrual syndrome, COVID-19 stress had a significant direct effect on premenstrual syndrome(β=4.907, p=.002), and depression(β=6.780, p<.001), and depression had a significant direct effect on premenstrual syndrome(β=.383, p=<.001), coping with premenstrual syndrome had a direct effect on premenstrual syndrome(β=4.292, p=.030) respectively. The indirect effect of verifying the mediating effect in the relationship between COVID-19 stress and premenstrual syndrome confirmed that there was a statistically significant effect only in the path via depression(95% CI, 1.282 to 4.140). Therefore, it is necessary to develop an intervention strategy to reduce depression and alleviate premenstrual syndrome symptoms by controlling related stress, such as COVID-19 stress, in preparation for the outbreak of new infectious diseases and pandemic situations such as COVID-19.

This research suggests a method to contribute to the perfect execution of duty in prospective information warfare by inspecting network-based warfare, in which its basic concepts and efficient management plans are provided; it is especially important, due to growing focus on information warfare caused by sudden improvements on information technology which affects not only civil matters but international military affairs as well. For this purpose, this research scrutinizes on the chronological organization of warfare traits during the information age, and information-warfare execution, as well as its effects, thereby providing proper management plans for network-based warfare.

As a new facet of international security realm in 21C, Information Warfare(IW) has rised new way of warfare and demostrated its efficiency in battelfield. With the rapid development of information technology, indeed, it is difficult to estimate the future of IW. While there are a lot of discussion on the clear concep of IW, it is clear that IW has the factor of psychological warfare, so-called cyber psychological warfare. Considering the security environment of Republic of Korea(ROK), the cyber psychological warfare has the significant importance for national security. While it has to deal with the cyber psychological warfare of North Korea, it also try to cope with the various threaten of international conflicts to protect Korean people and national interest.

This study investigated the quality characteristics of Chun-dubu(whole soybean curd) to which ginseng powder was added. The overall composition of the material was moisture $80.11{\pm}0.32%$, crude protein $6.04{\pm}0.007%$, crude fat $5.85{\pm}0.007%$, and crude ash $1.06{\pm}0.014%$(all w/w). The total microorganism count was 3.57 log CFU/g, whereas that of control Chun-dubu was 4.82 log CFU/g after 15 days of storage at $5^{\circ}C$. No coliforms were detected in Chun-dubu with added ginseng powder, whereas the control Chun-dubu coliform count was 3.52 log CFU/g after 15 days of storage at $5^{\circ}C$. When textural properties were considered, all of hardness, springiness, and chewiness rose during storage at $5^{\circ}C$. The sensory characteristics of Chun-dubu with added ginseng powder rated higher(from 5.80 to 6.10) than those of control Chun-dubu.

공개전 대규모 무상증자에 대한 시각은 기업가들이 공개전에 물타기증자를 하여 상장함으로써 과대한 자본이득을 취한다는 것이다. 본 연구는 1988년부터 1990년까지 공개한 282개 기업을 대상으로 공개전 무상증자를 실시한 기업의 특성과 영향을 분석하였다. 공개전 대규모 무상증자를 실시한 기업들의 공개전 주당순이익은 무상증자를 전혀 실시하지 않은 기업의 주당순이익의 3.3배로 높아, 주당순이익을 같은 시기에 공개하는 기업의 수준으로 낮추기 위하여 무상증자를 실시하는 것으로 사료된다. 또한 무상증자비율은 초과수익률과 유의적인 관계를 갖지 않으며, 내부자거래자료를 분석한 결과 특별한 사항을 발견할 수 없었다. 공개후 장기초과수익률 분석에서 발견된 장기 저성과 현상은 금융기관을 제외한 모든 제조업 공개기업에 공통된 현상으로 장기 저성과와 무상증자비율은 유의적인 관계를 갖지 않으며, 장기 저성과 현상은 공개기업들이 영업성과가 최정점에 있을 때 기업을 공개하고 이후 영업실적이 악화됨에 따라 천천히 주가에 반영되는 것으로 이해된다. 본 연구는 대규모 무상증자를 실시한 이유를 제시하고 있으며, 대규모 무상종자가 상장후의 주가에 전혀 영향을 주지 않는다는 것을 발견하였다. 따라서 공개전 무상증자를 결코 나쁜 시각으로만 볼 수 없다고 사료된다.
