The purpose of this study is to analyze the compositions and characteristics in cultural programs of the 1988 Seoul Olympics and the 2018 PyeongChang Winter Olympic Games. A research method was considered the developmental aspects of Cultural Olympics in all-time Olympic Games and the cases of Cultural Olympics in a host country through a documentary research method. The compositions and characteristics in cultural programs of the 1988 Seoul Olympics and the 2018 PyeongChang Winter Olympic Games were diversely analyzed. The results are as follows. First, a concept of a cultural program was deepened and developed at the 1992 Barcelona Olympics. In the wake of the 2010 Vancouver Olympics, IOC published the Cultural Olympic Guide. Through the 2012 London Olympics, the Cultural Olympic Guide was revised. Second, the cultural programs of the 1988 Seoul Olympics and the 2018 PyeongChang Winter Olympic Games showed the characteristics of image change & status and of the international exchange strengthening in a host country and a holding city. Third, in terms of cultural programs, the 1988 Seoul Olympics comprised the celebrations, performances & exhibitions amid the Culture and Arts Festival, and the International Academic Conference. The 2018 PyeongChang Winter Olympic Games were composed of performances, exhibitions, festivals, humanities & experience, and educational events. Fourth, the 1988 Seoul Olympics included the key element of forming a program that equally has the characteristics with the harmony between tradition and modernity, with the promotion of the excellence in Korean traditional culture & the spread in a bond of sympathy, and with various cultures and arts in each region. Also, the 2018 PyeongChang Winter Olympic Games pushed ahead with the strategy dubbed 'The Olympics in which there is culture day after day, in which provincial residents participate, and in which the cultural heritage is left' in order to systematically expedite the cultural Olympics.

The wearing slider of the rail motor car's pantograph is considerable changed by the type and the material properties. Especially, precipitation and arc influences are main factors decided to life time of wearing slider and contact wire. This study is wearing phenomenon analysis of Cu-type wearing slider with high electric conductivity and resistance arc through experiment by running train. Author observed that wearing phenomenon of Cu-type wearing slider with normal and abnormal wearing characteristics and comparatively analysis precipitation, mileage and weight influences of exchanged Cutype and Fe-type wearing sliders. In this paper result showed that necessity for the application which is the Fe-type of wearing slider had superior wear resisting capacity etc., through tribology approach.

This study compared the sea surface wind pattern between model results from KMA operational model (RDAPS) and observational results from QuikSCAT in the 2005-2006 year. The mean spatial distributions of sea surface wind show the prominent seasonal patterns of summer and winter season adjacent to Korean Peninsular. The statistical analysis also shows well seasonal variation of sea surface wind patterns between model and observation results. The BIAS value represents less than -0.5 m/s and -1 m/s in summer and winter seasons, respectively. The spatially averaged correlation coefficient shows larger than 0.7 and 0.8 in summer and winter seasons, respectively. The correlation coefficient of winter season shows higher value than that of summer season in the comparison between model and observation. This results show that the RDAPS model simulate well strong sea surface wind in winter season rather than weak sea surface wind in summer season.

Until recently, academic consensus held that Zhou Dunyi's Taijitu (Taiji Diagram) originated from Cantongqi. However, a new debate has arisen wherein some scholars question that theory and related theories. They criticize these previous theories because the books and charts used as evidence in those theories were published after the lifetime of Zhou Dunyi, and this disqualifies their influence on his thought. However, identifying certain authors as being of a slightly later period than Zhou Dunyi does not definitively answer whether or not Zhou Dunyi's diagram was based on Cantongqi. I approached this problem from a different perspective. Zhou Dunyi's Taijitu is based on the system of taiji (Taiyi), yin-yang, and the five movements. Consequently, the formation of this system should be traced back historically. In the process of tracing it back, I intended to explain that the main character of Cantongqi is closely related to the formation of the system of taiji (Taiyi), yin-yang, and the five movements. The system of taiji (Taiyi), yin-yang, and the five movements was first established as a religious theological system in the Han Dynasty. In this process, yin-yang and the five movements were combined by Dong Zhongshu, and the five movements were introduced by Han Dynasty scholars as a method of interpreting the I-ching. However, Han Dynasty scholars did not form this system. In the late Han Dynasty, Cantongqi adopted the theological system of yin-yang and the five movements to theoretically form the system of taiji (Taiyi), yin-yang, and the five movements. Cantongqi was able to form this system because of the logic that yin-yang is the essence of the I-ching. Cantongqi does not have the same schematic as Taijitu. However, the system of taiji (Taiyi), yin-yang, and the five movements appears and extracts the components that make up Taijitu. Therefore, I do not think we should hastily agree with the recent claims made by scholars.

시설원예라 함은 프라스틱하우스, 유리온실과 같은 시설안에서 작물을 주위의 불량한 환경조건에서 보호하는 동시에 생력화할 수 있는 장치를 도입하여 자본집약적으로 원예작물을 재배하고 비수기에 생산물을 공급하여 농가소득을 향상하고 국민식생활 개선에 기여할 수 있는 재배형식이다. 우리나라는 북반구에 위치하여 4계절이 뚜렷하고 동계에는 기온이 매우 낮아 적당한 보호조치 없이는 작물을 재배할 수 없다. 즉 시설원예는 동계 저온기의 작물생산이 주가되므로 보온 및 기온이 중요하고 또 동계에는 일조시간이 짧고 광도가 낮아 일사량이 부족하며 시설내에서는 더욱더 부족하게 되므로 광선관리에 신경을 쓰지 않으면 안된다. 그리고 고정된 하우스내에서 작부회수를 증가시키고 재식밀도를 높이게 되면 자연 다비재배를 해야하므로 염류농도의 장해와 가스 피해가 우려된다. 또한 환기불량으로 인한 탄산깨스의 부족과 다습으로 인한 병해의 발생이 심한 점이 있으므로 적절한 준비와 관리대책을 세우지 않으면 안된다.

미래에 예측되는 수요를 보다 바람직한 방향으로 개선하고자 시행하는 제반활동을 의미하는 전력수요관리는 고유가와 온실가스 문제가 큰 현안이 된 지금의 상황에 비추어 볼 때 그 중요성이 날로 커지고 있다고 할 수 있다. 그러나 현재의 수요관리 시스템은 하계의 수급문제 해결에 그 초점이 맞춰져 있으며, 현재 문제가 되고 있는 동계 전력수급문제에 대해서는 특별한 관리 대책이 없는 상황이다 따라서 동계 수요관리를 위한 수요관리자원 발굴 작업이 시급하며, 그 대책중의 하나로 PV(Photovoltaics) DSM(Demand Side Management)를 제안하고, 실제 건물에 적용 시 그 효과에 대하여 알아보았다.

한국산 야생 생쥐(Mus muscurus subspecies)와 동계교배 계통인 BALB/c의 정모세포에서 감수분열에 따른 염색체의 chiasma 말단화 여부와 chiasma 빈도, X-Y 염색체의 조기 분리 빈도 등을 조사하였다 한국산 야생 생쥐에서는 chiasma 말단화가 일어나지 않는 것으로 나타나 말단 chiasma는 말단 부위에 특이적으로 생긴 chiasma로 생각되며, chiasma 빈도의 감소와 univalent 빈도의 증가에 관한 ageing의 영향도 관찰되지 않았다. 불임개체에서 X-Y 염색체 조기 분리가 낮은 빈도로 나타나 동계교배 계통과는 다소 상반된 결과를 보였고, chiasma 빈도는 한국산 야생 생쥐가 동계교배 계통에 비해 다소 높게 나타났으며 복사기, 이동기 및 중기 1을 거치는 동안 거의 일정한 수준을 보여주었다. 또한 한국산 야생 생쥐에서 특징적으로 개재 chiasma 빈도 보다 말단 chiasma 빈도가 높게 나타났으며 이에 대해서는 부가적인 연구가 뒤따라야 할 것으로 사료된다.

Among the biodegradable liquid waste treatment and disposal methods, ocean dumping is a cost-effective and productive manner considering reuse point of view However, when biodegradable liquid waste is dumped in the ocean, oxygen consumption by the decomposition of organic matter must be considered. The purpose of this study is to determine the maximum allowable concentration and dumping rate in the southern waters of the East Sea based on dissolved oxygen level. Streeter and Phelps' model has been used to determine the maximum allowable concentration. Factors in this model, deoxygenation constants and reaeration coefficients, have been determined by appling oxygen consumption method and closed system model. Deoxygenation constants and reaeration coefficients from surface to each standard depth are $0.24\~0.29/day\;and\;0.03\~0.39/day$ in summer, $0.17\~0.20/day\;and\;0.04\~0.56/day$ in winter, respectively. The allowable organic matter concentration($mgBOD/\iota$) to the dissolved oxy-gen sag value of $5mg/{\iota}$ is represented $17.23\times(H)^{-0.37}$ in summer, and $64.96\times(H)^{-0.52}$ in winter by mixing depth(H, m). Csanady's experiment has been applied to estimate the optimum dumping rate. The optimum dumping rate($R,\;m^3/sec$) can be written as a product of the beam(b, m) and the draft(h, m) of vessel, and biochemical oxygen demand of waste($L_n,\;mg/{\iota}$) $R=275{\times}bh^{0.63}L_n^{-1}$ in summer $=745{\times}bh^{0.48}L_n^{-1}$ in winter. The difference of dumping rate between in summer and winter is due to the oxygen distribution.
