Narcissism is a pathological phenomenon and narcissistic subject always needs to put itself on the top and has interest in nothing but its own determination. The protagonist of Adversary by ?mmanuel Carr?re does pay careful attention to what others are thinking of him while he does not distinguish difference between object of love and himself. So he can be allegedly narcissistic subject. And it can be said that the behaviors of Mary in the movie Under the sand by Ozon are included in narcissism in that narcissistic subject has the characteristics that idealizes the object of libido. However, in this study, the heroine is examined based on such a point that the object of love and extreme idealization incline toward others. We call this case reverse-narcissism. In Part 2, it is investigated what relation narcissism as an unconscious psychological tool has with Oedipus complex, which plays an important role in forming human psyche. For instance, disappointment caused by prohibition at the oedipal stage is too severe, which creates superego and its idealization to protect in such a way that narcissistic regression can not be done. Cases of extremely big gap between ego and ideal type are perversion, impostor, mania, paranoia, etc, where narcissistic and oedipal elements are combined to affect.

The goal of cell stem cell technology is to produce a viable and genetically normal animal. To achieve this goal various laboratories have followed 2 different pathways beginning with either the culture of 1) single or pooled ICMs grown with or without a feeder layer or 2) single or pooled 16-20 cell stage embryos grown with a feeder layer. Also, thus far embryonic cell cultures or lines have been established by several methods including loose suspension culture for short-term cultures and more commonly murine or bovine fibroblast feeder layers for long-term culture. Pluripotent lines have been derived from 16-cell through blastocyst inner cell mass stages. The efficiency of establishing cell lines and cell proliferation apper to be affected by the number of cells or embryos starting the line. Most attempts to produce offspring from long term STO cell feeder layer cultured ICM or morulae derived ES cells have resulted in pregnancy failure in the first trimester when ES cells were used in cuclear transfer or have failed to retain ES cells in the progeny produced by chimerization. The exception is 1 chimeric fetus from use of morula ES cells in the chimerization with early embryonic cells. There is much to be learned yet about ES cell culture requirements for maintenance of totipotency. If bovine ES cell lines loose imprinting pattern and totipotency with long-term culture and passage as suggested for mouse ES cells, we may be limited to the use of short-term cultures for multiplication of embryos and efficient production of transgenic animals. No bovine ES cell system has yet met all of the criteria indicated for a totipotent ES cell line.

복합수력학문제를 효과적으로 해결하는 방법중의 하나로써 단위크기 무차원화를 통한 연역적 해석방법을 2가지 실례를 들어 서술하였다. 이와같은 해석방법은 결코 모든 문제에 있어서 전능의 절대확실한 방법은 아니다. 그러나 이 해석방법은 적어도 주어진 문제의 해결에 자명한 접근방법을 제공하며 또한 그와같은 해석을 통한 결과가 실제 어떤 조건하에서 이용될 수 있는가를 명백히 밝혀준다. 따라서 복합수력학 문제에서뿐 아니라 다른 영역의 난해하고 새로운 현상의 문제에 있어서도 단위크기 무차원화를 통한 연역적 해석방법이 의미있고 유용한 결과를 가져다 줄 수 있을 것으로 생각된다.

본 논문에서는 OFDM 변조와 단축블록터보코드를 사용하는 시스템에서 단축블록터보코드를 반복 복호하는 과정에서 채널상태정보(Channel State Information : CSI)값을 적용한 방법을 새롭게 제안하였다. 새롭게 제안된 시스템의 경우 1회의 같은 반복 횟수를 가지는 경우에 BER 성능이 신호의 변조방식에 따라 4.5[dB] $\sim$ 10.0[dB] 정도의 뛰어난 전능 향상을 보였다. 또한 CSI값을 적용하고 1회 반복 복호한 시스템이 CSI값을 적용하지 않은 기존의 복호 시스템의 4회 반복 복호한 경우보다도 1[dB] $\sim$ 7.0[dB]의 성능 향상을 보임으로써 반복 복호의 시간을 70[%] 이상 감소시킬 수 있다. 따라서 단축블록터보코드를 반복 복호하는 경우에 CSI값을 적용한 시스템이 뛰어난 성능 향상과 더불어 반복 복호 시간을 줄임을 알 수 있었다.

21세기 신기술은 나노기술(Nano Technology,NT)을 통해서 이뤄질 것으로 보인다. 로마를 통하지 않으면 어디로도 갈 수 없었던 것처럼 작게 생각하지 않으면 첨단기술에 접근할 수 없는 상황이 펼쳐지고 있다. 이전에 재료공학자ㆍ기계공학자 불리던 연구자들이 미지 세계 개척자로서 작은 것들을 새롭게 창조하는 '나노의 방주'에 서둘러 들어서고 있다. 나노의 방주에는 화학뿐만 아니라 물리ㆍ건축ㆍ공학 등이 자유롭게 넘나든다. 이들은 혜성처럼 등장한 나노라는 화두를 중심에 놓고 서로 영향을 주고받으며 기술의 향방을 결정하고 있다. 나노기술이 열려라 참깨식의 마술적 주문으로 작용하는 셈이다. 전능의 신 노릇을 하는 나노는 새로운 것을 만들어낼 뿐 아니라 다른 기술에 놀라운 능력을 부여하기도 한다. 종교인들이 신을 통해 새롭게 태어나듯 일상적 기술이 나노를 통하면 황금알을 낳는 신기술로 거듭나는 것이다. 그 이름에서도 알 수 있듯이 한국나노의료기는 현실보다는 미래지향적인 전략적 기업으로 발전을 거듭하고 있었다

Naringin, major citrus flavonoids, has been identified to exert antioxidative, antidiabetic, and lipid lowering effects. In this study, we examined the effect of 0.2 g/kg, 0.5 g/kg naringin supplementation for 3 times/week for 5 weeks on lipid metabolism and antithrombotic capacity in rat. Eighteen five week-old Sprague Dawley(SD) female rats, which had initial body weights of $246{\pm}9g$, were randomly divided into three groups: Control (non naringin group); Low (0.2 g/kg naringin-supplemented group); High (0.5 g/kg naringin-supplemented group). Three groups of rats were supplemented with three experimental diets for 5 weeks and we investigated antithrombotic capacity before sacrifice. Naringin did not significantly alter the body weight gain, relative organ weight. However, the level of serum triglyceride, serum free fatty acid, serum total lipid and serum glucose levels were significantly lowered compared to those of control. The high group (0.5 g/kg naringin-supplemented group) was showed significantly increased bleeding time compared to control group. These results suggest that naringin supplemental diets reduces the level of hypertension, glycosuria and fatness on the female SD rats, when orally administered below the dosage 0.5 g/kg for 5 weeks.

This study was performed to investigate the effect of dried powder of chestnut on lipid metabolism, anti-thrombotic effect in rats. Thirty 5-week-old male Sprague Dawley (SD) rats were randomly allocated into five groups and used for experiment. We examined the lipid metabolism and antithrombotic capacity of SD rats administered for 5 weeks with 0.16 g/kg, 0.5 g/kg chestnut flesh powder and 0.16 g/kg, 0.5 g/kg chestnut inner shell and flesh powder mixture, respectively. Food intake, body weight gain and food efficiency ratio were also checked. The levels of serum triglyceride and tree fatty acid were not statistically significant between the all experimental groups. However, the antithrombotic capacity and total lipid levels of the treatment groups were significantly lower than those of the negative control group. These results suggest that the supplementation of chestnut on diet lower the total lipid level in SD rats.

Ursolic acid (UA) a bio-active ingredient found in a variety of fruits and vegetables, and it has potent antioxidant activity. However, the role of UA in mouse embryonic stem (ES) cells is poorly understood. This study investigated the functional role of UA in regulating the development of mouse ES cells under hypoxia. Hypoxia did not exert a significant effect on the undifferentiated state of mouse ES cells. However, it induced reactive oxygen species (ROS) generation and increased the level of lactate dehydrogenase (LDH) production at 48 h of hypoxic exposure. Conversely, oxidative stress induced by hypoxia was significantly inhibited by UA ($30{\mu}M$) pretreatment. Hypoxia significantly decreased cell survival and the level of [$^3H$] thymidine incorporation, both of which recovered following pretreatment of UA. In addition, UA decreased the apoptotic effect of hypoxia by attenuating caspase-3 cleavage or by recovering cellular inhibition of the apoptotic protein (cIAP)-2 and Bcl-2 expression. We further found that UA decreased senescence-associated beta-galactosidase activity. We suggest that UA is a natural antioxidant and one of the functional modulators of hypoxia-induced survival, apoptosis, proliferation, and aging in mouse ES cells.
