The goal of this paper is that we know the usefulness of echo-planar imaging(EPI) for discriminate between hepatocellular carcinoma(HCC) and hemangioma. We get a time signal intensity curve for liver diseases from the dynamic contrast enhancement images and compared and analyze both the contrast ratio(CR) and the contrast to noise ratio(CNR) using echo planar imaging. The obtained results are follows : 1. Hepatocellular carcinoma was shown the best contrast after about 20 seconds when Is the earlist time in the main artery, and then reduced. The center where is disease was shown the characteristic that the best contrast is appeared after about 35-45 seconds and then slowly reduced. Liver parenchyma was shown the best contrast and reduced after 60 seconds. 2. The peripheral nodular of hemangioma was shown the better contrast soon. On the other hend, the contrast of center where is disease started to increase after 60 seconds and was equal to that of liver parenchyma. Increasing of the contrast continued after. 3. Turbo SE technic was used, the average of CR for hepatocellular carcinoma was $36.7{\pm}1.2$ and the average of CNR was $2.4{\pm}3.2$, while the average of CNR for hemangioma was $54.9{\pm}1.0$ and the average of CNR was $9.7{\pm}1.3$. 4. EPI technic was used, the average of CR for hepatocellular carcinoma was $47.8{\pm}1.2$ and the average of CNR was $3.4{\pm}2.1$, while the average of CNR for hemangioma was $75.7{\pm}2.2$ and the average of CNR was $9.5{\pm}1.1$. According to above we can find that hemangioma is more bright than hepatocellular carcinoma and the difference of brightness between hepatocellular carcinoma and hemangioma is useful sequence.

This study is intended to empirically investigate determinants of the degree of standardization vs. adaptation in global marketing programs for Korea firms. Our study has two main focuses. First, our study takes a global perspective instead of a binational, i. e., home vs. foreign perspective. Second, we accommodated two conflicting veiws - contingency and resource-based views in explaining determinants of global marketing strategy. As such determinants, we considered global market dynamism and complexity from a contingency view and global marketing assets from a resource-based view. Surveys were conducted with 128 Korean firms engaged in global marketing. Our study found that Korean firms with global assets tend to engage in highly standardized global marketing programs. On the other hand, global market dynamism and complexity did not show statistically significant relationships with the degree of standardization vs. adaptation. The findings suggest that a resource-based view may be more powerful than a contingency view in explaining global marketing strategies of Korean firms.

To understand 'Moving up the charts' as a dynamic phenomenon in the K-pop entertainment industry, this study specifically analyzed the 'Moving up the charts' of 「Rollin'」 sung by 'Brave Girls'. First, the context and process related to 「Rollin'」 were described in detail, and the performance as a sound source and business were described. Subsequently, six factors were analyzed and presented as causes for 'Moving up the charts': 'Existence of specific possible triggers', 'Attractions of content itself', 'Inflow of new male fans', 'Turning weaknesses into strengths as idol', 'Psychological empathy with stories of real group' and 'Fast response and communication of agency'. Due to the influence of 'Moving up the charts', two changes were presented: 'Expansion of popularity and interest and expansion beyond songs' and 'Forming a consumer group with high purchasing power'. Through this, this study discussed the meaning, role, and possibility of 'Moving up the charts' in the K-pop entertainment industry. In the future, it will be necessary to recognize 'Moving up the charts' in the music market as a remarkable phenomenon, and to understand the importance of new idol consumer class as well as the use of related media such as YouTube.

The purpose of this study was to criticize the sport culture of babyboom generation women in Korea society. In the traditional society with Confucianism dominating, women were told to walk in small strides with modesty, keep footsteps narrower than the size of foot and never run frivolously. But in the modern society, many middle aged women-babyboom generation who was born in 1955-1963 and the first generation was served high level education engaged to enjoy various physical activities. For this study, there is a important method to analysis through three oral history interviews. It can be seen the cultural context in the result of sport as a play, restricted P·E class, forced motive-a good motherhood, survival fitness and ready for later life. These results will can be founded as a reality of dynamic relations and provided implications about founding the important of women voice and creating important data for people who want to be engaged in sports as a physical activities.

문화정체성은 실로 구성적 성격을 지닌 개념으로, 문화정체성의 구성은 상황 (그리고 역사)과 상념 사이에서 발생하는 역동적인 상호작용의 결과에서 비롯된다. "다약인"이라는 개념의 형성 및 구성에 있어서도 서로 다른 다양한 힘이 작용해왔다. 식민 지배기에 탐험가들과 학자들은 서구적 방식으로 "다약인"의 구성을 구체화시켰고, 이것은 해방 이후 인도네시아 국가의 향방에 순차적으로 영향을 끼쳤다. 다약인 정체성의 구성과 그 동인에 관한 논의는 머리사냥, 긴 형태의 가옥들, 종교 등과 같이 다약인을 그려내는 특정한 이미지에 다만 집중하고, 다약을 그려내는 이러한 이미지들이 오늘날 다약인 정체성과 어떠한 연관성을 지니는가에 관한 논의이다. 과거 머리사냥 풍습에 관해서도 다약인에게 있어서 머리사냥의 의미와 관례를 충분히 설명할 수 있는 분석이 현재 전무하다. 다약인 사회의 또 다른 주요 특징은 독특한 주거양식에서 찾을 수 있다. 주거양식은 대부분의 문헌에서 추정해온 것처럼 독특한 것이 아니라 오늘날에 이르기까지 다약인은 껜야인처럼 종종 연립가옥(라민)을 그들의 중심문화로 여긴다. 깔리만딴 동부에 위치한 롱메카에서 문화와 청년축제가 개최되었는데 이 축제의 전체 진행은 자문화의 재건과 밀접하게 연관되어있다. 2006년에 끄라얀에서 개최된 이와 유사한 한 문화축제는 페뭉 에라우 펜제라니(Pemung Erau Pengerani)라고 불린다. 종교 역시 다약인의 인류학적 설명에 있어서 주요 특징으로, 다약인은 보르네오에 거주하는 비(非)무슬림교도들로 정의된다. 과거에는 거의 대부분의 사람들이 정령신앙을 숭배했으나, 다약인들 사이에서 기독교로의 대규모 개종이 일어나면서 다약인은 기독교도와 일반적으로 동일시되었다. 깔리만딴 지역의 무슬림은 다약인이 될 수 없다는 게 일반적인 생각이다. 실로 다약인이 된다는 것은 수많은 힘들의 집합체로부터 그 구성이 이루어진다는 것을 의미한다.

The percentage of divorce has increased rapidly even in Korea where traditionally attaches great importance to a family. However most counselors apply counseling theories and approaches developed in the West when they do counseling for Korean couple. In fact, the culture of Korea carries characteristics of relationism under the Oriental religion like Shamanism, Buddhism, and Confucianism. Therefore it is not easy to gain sufficient counseling effect in Korea with such major counseling approaches. The Korean takes a serious view of family relations between father and son, Therefore the Koran society carries on a family line, devotes their lives to the cause of education, gies precedence to the elder. In such a cultural area, it would be quite helpful for counselors to focus their attention on various roles of each rather than focus on their conflict of intimacy itself.

Diffusion-weighted magnetic resonance imaging (DW MRI) is a fast unenhanced technique that shows promise as a stand-alone modality for cancer screening and characterization. Currently, DW MRI may have lower sensitivity than that of dynamic contrast-enhanced MRI as a standalone modality for breast cancer detection but superior to that of mammography, which may provide a useful alternative for supplemental screening. Standardized acquisition and interpretation of DW MRI can improve the image quality and reduce the variability of the results. Furthermore, high-resolution DW MRI, with advanced techniques and postprocessing, will facilitate better detection and characterization of subcentimeter cancers and reduce false-negatives and false-positives. Future results from ongoing prospective multicenter clinical trials using standardized and optimized protocols will facilitate the use of DW MRI as a stand-alone modality.

The psychology of Carl G. Jung is often called an "ancilla religionis"(servant of religion, James Heisig), by which Jung's understanding of the unconsciousness of human being as the religious one is well expressed. According to Jung the dichotomy between the consciousness and the unconsciousness of men is reconciled in the various religious symbols of the world religions. He also asserted that the religious symbols must be understood and interpreted by a symbolical way. When the religious symbols are understood literally and dogmatically, they lost their dynamic power to bring salvation to men. In this paper I try to understand the essence of the symbolical and intuitional understanding of the exclusiveness of Jesus Christ. The confession of the Christianity that only Christ, once for all, could bring the salvation to the whole humankind is to be interpreted by a symbolical and intuitional way. That means, Christ is to be understood as a always new being at every time when he is confessed as a salvator. Christ as a symbol could never be a historical past. I mentioned about the understanding of Buddha by Muneyoshi Yanagi, a Japanese Shinto Buddhist, in order to show how such a symbolical and intuitional understanding of the Christ could be possible.

Purpose : To compare dynamic susceptibility contrast imaging, diffusion-weighted imaging, and susceptibility-weighted imaging (SWI) for the differentiation of tumor recurrence and delayed radiation therapy (RT)-related changes in patients treated with RT for primary brain tumors. Materials and Methods: We enrolled 24 patients treated with RT for various primary brain tumors, who showed newly appearing enhancing lesions more than one year after completion of RT on follow-up MRI. The enhancing-lesions were confirmed as recurrences (n=14) or RT-changes (n=10). We calculated the mean values of normalized cerebral blood volume (nCBV), apparent diffusion coefficient (ADC), and proportion of dark signal intensity on SWI (proSWI) for the enhancing-lesions. All the values between the two groups were compared using t-test. A multivariable logistic regression model was used to determine the best predictor of differential diagnosis. The cutoff value of the best predictor obtained from receiver-operating characteristic curve analysis was applied to calculate the sensitivity, specificity, and accuracy for the diagnosis. Results: The mean nCBV value was significantly higher in the recurrence group than in the RT-change group (P=.004), and the mean proSWI was significantly lower in the recurrence group (P<.001). However, no significant difference was observed in the mean ADC values between the two groups. A multivariable logistic regression analysis showed that proSWI was the only independent variable for the differentiation; the sensitivity, specificity, and accuracy were 78.6% (11 of 14), 100% (10 of 10), and 87.5% (21 of 24), respectively. Conclusion: The proSWI was the most promising parameter for the differentiation of newly developed enhancing-lesions more than one year after RT completion in brain tumor patients.
