Tumor lysis syndrome is rare in hepatocellular carcinoma (HCC), but it has been reported more frequently recently in response to treatments such as transcatheter arterial chemoembolization (TACE), radiofrequency thermal ablation (RFTA), and sorafenib. Tumor lysis syndrome induced by low-dose steroid appears to be very unusual in HCC. We report a patient with hepatitis-C-related liver cirrhosis and HCC in whom tumor lysis syndrome occurred due to low-dose steroid (10 mg of prednisolone). The patient was a 90-year-old male who presented at the emergency room of our hospital with general weakness and poor oral intake. He had started to take prednisolone to treat adrenal insufficiency 2 days previously. Laboratory results revealed hyperuricemia, hyperphosphatemia, and increased creatinine. These abnormalities fulfilled the criteria in the Cairo-Bishop definition of tumor lysis syndrome. Although the patient received adequate hydration, severe metabolic acidosis and acute kidney injury progressed unabated. He finally developed multiple organ failure, and died 3 days after admission. This was a case of tumor lysis syndrome caused by administration of low-dose steroid in a patient with HCC. (Clin Mol Hepatol 2015;21:85-88)

1980年代의 韓國의 實質換率 : 충격의 상대적 중요성 the realative importance of the structural shock

金鎭玉 제주대학교 1994 논문집 Vol.39 No.1

The main purpose of this paper is to identify the sourses of U.S./Korean real exchange rate fluctuations under managed floating exchange rate(1980-1990). Using unit root test, we found that there was little evidence supporting the stationarity of the real exchange rate. The real exchange rate was a random walk, which says that there was a nonstationary real shock in the economy. Furtheremore coinegration test between nominal and real exchange rate failed, which implies that there was a nonstationary nominal shock. Equilibrium approach〔Stockman(1987)〕 argued that given price flexibility nominal shocks can not induce changes in the real exchange rate even in the short run. On the other hand, real shocks such as real disrurbances to supplies and demands for goods can cause changes in the real exchange rate. By contrast, disequilibrium view〔Dornbush(1976)〕 suggests that given short-run price rigidity, nomianl shocks may cause the real exchange rate depreciations. Even if money is not neutral in the short run, long-run neutrality of money guarantees that nomianl shocks of any varity have no permanent effects on the real exchange rate. these two approaches have a common view that (1) nomial shock can not affect the real exchange rate in the long run, (2) real shocks do matter in the movement of the real exchange rate. Given the long-run neutrality of money and the long-run exogeneity of the relative output level, we employed the Structural Vector Autoregression(SVAR) framework pioneered by Blanchad and Quah. Using SVAR, we showed that demand shocks such as the change in government spending was the most important in explaining the movements in the real exchange rate. Also we found that the nominal shock such as monetary shock was slightly important relative to supply shock.

Oxygen therapy is clear benefit in the treatment of tissue hypoxia, but high concentrations and long term exposures of oxygen carry the risks of detrimental physiologic changes and tissue damages. Tissue damages involve decreased surfactant production,alveolar edema, and alveolar hemorrhage. In spite of these damage, diagnosis of oxygen toxicity is difficult in many clinical settings. In this study, we measured lung compliance to evaluate the oxygen toxicity in 60 white rat of 100-150 g body weight Rats were divided into 6 groups. Group I was control graup, exposed to room air, group II -group V were exposed to 100% oxygen, group II for 24 hours, group IlI for 48 hous, group IV for 72 hours, and group V for 96 hours. Group VI was exposed to oxygen in serial as 30% oxygen for 24 hours, 60% oxygen for 24 hours and then 100% oxygen for 96 hours. After oxygen exposure we obseved changes of lung compliance and pathologic findings, compliance of group V was 15.94 mL/cmH2O significantly lower than that of eontrol group (p$lt;0.05) and lung weight of group V was 2.16 g/100 g heavier than the other groups (p$lt;0.05). Although we found oxygen tolerance was developed in group V, we could not differentiate the degree of pathologic damage cauesd from oxygen toxicity by pathologic findings. We concluded that the measurement of lung compliance is valuable in diagnosis of oxygen toxicity and thus in reducing lung damages.

디킨즈의 『황폐한 집』: 에스더 인물과 모성의 중요성

김진옥 신영어영문학회 2001 신영어영문학 Vol.19 No.-

Dickens' critics have found Esther irritating and insipid; they evaluate Esther's narrative as no more than a comforting contrast to the third person omniscient narrative. However, I argue that Esther has ability to represent herself as a subject: As an agent, she is dependet on her status as a person who lost her mother. For Esther, a missing mother signifes anxiety and fear; as the figure of psychological origins. Esther's mother stands as the source of subjectivity and individual identity. The loss of her mother represents a crisis regarding the conditions of individual identity. However, the death of a mother in this novel brings about the birth of an authorial subject. Esther's narrative, which focuses on maternal absence and loss, leads Esther to be an authorial subject. Melanie Klein suggests the theories of gender and subjectivity: I argue that Klein challenges maternal marginalization through mother-contered theories of infant developments. As Klein's pattern focuses on the return of a mother, this novel emphasizes maternal loss, and eventually maternal return. In Dickens' Bleak House, Esther's autobiographical narrative demonstrates the function of maternal absence for the construction of a speaking subject. In this paper, I examined the influence of maternal absence in sociological aspects as well as in psychoanalytic aspects. Dickens indicates the social problems that orphans such as Esther, Jo, and Caddy go through. Critics have noted the ambivalence and rage which Dickens directs toward mothers. Children are the only true adults: Mrs. Pardiggle and Mrs. Jellyby are malign mothers. By using these maternal figures, Dickens deconstructs the traditional concept of Victorian women. Esther is surely the ideal homemaker; every aspects of her identity remains unfixed and unstable. In his location in Esther of an ideal of domesticity, Dickens deconstructs the traditional ethic of stability and constancy. Even though Esther suffers from her pain due to the loss of her mother, she becomes empowered as a narrator. The death of a mother announces to Ester the possibility of her own life and the formation of her identity. I would suggest that her narrative power is articulated over the loss of her mother. The novel concludes in a moment of rhetorical indeterminacy, in which Esther is effaced by the imposition of her text. Esther exists in the realm between death and subjectivity, between fiction and autobiography, and between the issues of her mother's body and the issue of Esther's own subjectivity. Thus, the loss of Esther's mother is clearly the cause, the formative condition and the personal crisis, which finally leads Esther into the formation of her own subjectivity.

This paper presents a lip print recognition by pattern kernels for a person identification. A lip print recognition has been developed less than the other human physical attributes of a fingerprint, a voice pattern, a retinal blood/vessel pattern, or a facial recognition. The merit of a lip print recognition by CCTV camera is linked with other recognition systems such as retinal/iris eye and face. A new method with multi-resolution architecture is proposed to recognize a lip print by the pattern kernels. A set of the pattern kernels is a function of some local lip print pattern masks. This function converts the information on a lip print into the digital data. The recognition in the multi-resolution system is more reliable than recognition in the single resolution system. The results show that the proposed algorithm by the multi-resolution architecture can be efficiently realized.

In network delivery of compressed video, packets may be lost if the channel is unreliable. Such losses tend to occur in burst. In this paper, a temporal and spatial error resilient video encoding approach is developed to facilitate the error concealment at the decoder against burst errors. Block interleaving scheme is introduced to isolate erroneous blocks caused by packet losses for spatial area of error concealment. Data hiding is applied to add protection parity bits for motion vectors between intra frames or continuous inter frames for temporal area of error concealment. Since bidirection interpolation for error concealment is adapted to error blocks at decoder, error occurred during the transmission are concealed fast and properly. In this study, data hiding is used to reduce a complexity of error concealment at the decoder. A set of feature are extracted at the encoder and embedded imperceptibly into the host media. If some part of the media data is damaged during transmission, the embedded features can be extracted and used for recovery of lost data. Experimental results suggest that our approach can achieve a reasonable quality for packet loss up to 30% over a wide range of video materials.

名目換率制度와 實質換率의 變動行態 : 韓國經濟를 主軸으로 the case study for korea

This paper examines the validity of two basic tenets of the international finance literature : (1) the real exchange rate is a random walk, and (2) the behavior of the real exchange rate over time essentially depends on the nominal exchange rate regime. According to the first thenet, the presence of a unit root in the real exchange rate can not be rejected under fixed and flexible exchange rate regime, which implies that purchasing power parity(ppp) can not be a long-run relation since deviations from ppp are permanent in nature. Furthemore cointegration test between the nominal exchange rate and the real exchange rate failed under the flexible exchange rate regime, which says that there is a nominal shock which affects the national price levels. To examine the second tenet, VAR(vector autoregression) analysis was employed to identify the shocks which affect the real exchange rate behavior in fixed and flexible exchange rate regime. For U.S. vs Korea VAR system, the nominal shocks measured by the relative money supply ratio do not affect the real exchange rate movement under the fixed and flexible exchange rate regime, on the other hand the real shocks measured by the relative industrial production ratio do affect the real exchange rate under the flexible exchange rate regime, which partially supports the nominal exchange rate regime neutraity hypothesis. For Japan vs Korea VAR system, we can not identify any shocks to affect the movement in the real exchange rate under fixed and flexible exchange rate regime.
