국내 HPi(high speed-portable internet) 표준인 와이브로(WiBro)는 고속 데이터 전송과 다종 접속을 웠해 OFDM에 근간을 둔 OFDMA (Orthogonal Frequency Division Multiple Access) 다중 접속방식을 사용하고 있다. OFDM방식은 다수의 직교성을 지닌 반송파에 정보를 지닌 신호를 실어 데이터를 전송하는 방식으로, 직교 반송파를 구현하기 위해 IFFT/FFT 변환을 사용하여 하드웨어로 간단히 구현할 수 있는 장점을 가지고 있다. 반면에 OFDM은 동기화 오차에 대해 근 민감성을 보이고 있는데, 이에 대해 wibro는 60km/h의 속도에 대헤 안정적인 데이터 전송을 요구하므로 도플러 효과에 의한 영향이 매우 크다고 할 수 있으며, 다중 경로로 생기는 왜곡과 함께 시스템의 시간 동기화의 성능을 감소시키는 결과를 가져오게 되었다. 이에 대헤 휴대 인터넷 단말기 모뎀에서는 채널 환경에 대해 강인성을 지니도록 설계되었고, 비교적 큰 시스템이 모뎀으로 구현되게 되어 휴대 인터넷 단말기의 효율적인 저전력 설계 및 고속 이동시 우수한 성능을 위해 최상의 알고리즘 구현 및 최적화된 하드웨어 구조가 필요하게 되었다. 따라서 본 논문에서는 휴대 인터넷 단말기의 효율적인 하드웨어 구조 설계 대해 알려주고 있으며, 전체 시스템의 채널 환경하에서의 성능을 평가하여 보여주고 있다.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

주의력결핍 ㆍ 과잉운동장애 아동과 정상 아동의 청각적 집중 과정의 차이를 비교하기 위해 13명의 남자 환자와 8명의 정상 남자아이에게 청각적 주의집중 과제를 제시하고 사건관련전위를 푸리에 변환과 웨이브렛 분석법으로 비교 조사하였다. 각 군 아동의 표준자극과 표적자극에 대한 사건관련전위 파형을 푸리에 변환을 통해 주파수 차원에서 서로 비교하였고, 각 군 안에서 표적자극과 표준자극을 주었을 때의 진폭을 비교하였다. 표준자극에 대해서는 거의 대부분의 주파수와 좌측 위치에서 주의력결핍 ㆍ 과잉운동장애 아동이 정상아동보다 의미 있게 높은 전압을 나타내었다. 반면 표적자극에 대해서는 주의력결핍 ㆍ 과잉운동장애 아동이 정상 아동보다 더 높은 전압은 보이는 경우가 의미 있게 감소하였고 정상 아동이 주의력결핍 ㆍ 과잉운동장애 아동보다 큰 진폭을 나타내는 경우는 의미 있게 증가하였나. 이런 결과는 주의집중을 반영하는 Nd파형의 푸리에 변환 결과에서도 나타났다. 즉 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 정상 아동보다 지나치게 강한 반응을 보이지만 정작 과제를 수행해야 하는 자극에 대해서는 정상 아동보다 더 약한반응을 보이는 경향을 보였다. 주의력결핍ㆍ 과잉운동장애 아동은 정상 아동 보다 표적자극에 의한 진폭 증가를 보인 전극과 주파수 영역이 적었을 뿐 아니라 일부 파형은 표준자극을 주었을 때보다 표적자극을 주었을때 오히려 진폭이 의리 있게 감소하여서 이들이 표적 자극에 대해 활성이 억제됨을 알 수 있었다. 정상 아동들은 표준자극보다 표적자극에 대해서 거의 모든 전극 위치와 주파수 대역에서 의미 있는 진폭의 증가를 보였으나 전전두엽과 전두엽의 전극에서는 주의력결핍 ㆍ 과잉운동장애 아동이 더 큰 진폭을 보이는 경우가 관찰되었다. 웨이브렛 분석 결과 표준자극에 대해서는 주의력곁핍 ㆍ 과잉운동장애 아동이 정상 아동보다 자극이 제시된 후 0∼300msec 사이에 일어나는 전위가 통계적으로 의미 있게 컸다. 이런 차이는 주로 전전두엽과 전두엽 앞쪽, 그리고 측두엽 일부와 후두엽에서 두드러졌다. 그러나 두정엽과 중앙 영역의 전극들은 특히 300∼370msec 이내에 일어나는 전위에서 정상 아동이 더 활발한 전기 활동을 나타내었다. 표적 자극에 대해서는 두 군 모두 표준자극보다 전기 활성이 더 증가한 양상이었다. 표적자극에 대해서 주의력결핍 ㆍ 과잉운동장애아동은 전전두엽과 전두엽 영역에서는 여전히 정상 아동보다 더 활발한 전기 활성을 보였으나 두정엽과 측두엽에서는 정상 아동이 더 큰 진폭을 나타내었다. 이로써 주의력결핍 ㆍ 과잉운동장애 아동은 무시해야 하는 자극에 대해서는 지나친 반응을 보이며 주의집중을 필요로 하는 자극에 대해서는 정상 아동보다 저하된 반응을 보이는 것이 확인되었다. 이와 함께 푸리에 변환 등 주파수 차원 분석법과 웨이브렛 분석 방법의 유용성을 알아보았다. 중심 단어 : 주의력결핍 ㆍ 과잉운동장애 ㆍ사건관련전위 ㆍ푸리에 변환 ㆍ 웨이브렛 분석. Using Fourier transformation and wavelet analysis, we compared the auditory event-related poten-tials of the patients with attention deficit-hyperactivity disorders (abbr. ADHD, 13 boys) and normal control children (8 boys) Amplitudes of the event-related potentials which were calculated via Fourier transformation were compared between the groups and between conditions (non-target versus target) in each group. To the non-target stimuli, the patients with ADHD showed significantly greater amplitudes across almost all of the electrode sites and frequencies. To the target stimuli, the incidents which ADHD patients showed much higher amplitudes than normal controls significantly decreased, while those of the reverse results increased significantly. These results were consistent with the comparison results about negative difference wave (abbr. Nd wave) using Fourier transformation. In summary, it was proved that non-target stimulus which should be ignored elicited more robust electrical response from the patients with ADHD than normal children, but the target stimulus which required active processing did much less electrical activity in the patients. For the patients, they showed much inhibited electrical response to the target stimuli in some electrodes and frequency ranges. Normal children were more strongly stimulated by the target stimuli in almost all electrodes and frequency ranges than the patients, but less in prefrontal leads and frontal leads. Wavelet analysis results proved that early responses (0-300msec) to the nontarget stimuli of the patients were significantly greater than the normal controls in prefrontal, anterior frontal, some parts of temporal, and occipital lobes and that late response (300-370msec) were significantly lesser than normal children in parietal and central electrodes. Target stimuli elicited significantly higher electrical activity in both group than non-target stimuli did. Prefrontal and frontal lobes showed stronger responses in the patients than normal children irrespective of stimulus condition, but parietal and temporal lobes did higher activities in normal children than the patients only to the target stimuli. In conclusion, the patients wish ADHD showed much greater responses to the stimuli which should be ignored, but failed to activated the necessary processes to the target stimuli. Also, we found that the frequency-dimension analysis and wavelet analysis were useful for the signal processing such as event-related potentials. KEY WORDS : Attention deficit hyperactivity disorder ㆍ Event related potentials ㆍ Fourier transformation ㆍ Wavelet analysis.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherpy seems a logical choice for cancer chemotherapy. The Mitomycin C(MMC) adsorbed by the activated charcoal particles(CH) is relatively released when the drug concentration surrounding the carbon particles becomes low in the peritoneum of the peritoneal cavity. For the intraperitoneal chemotherapy on the advanced gastric adenocarcnoma, mitomycin C adsorbed on activated carbon particles was administered in the peritoneal cavity just before abdominal wall closure. The closed drainage tubes were inserted in the peritoneal cavity and clamped for tuo hours after completion of operation. MMC concentrations were serially measured in peritoneal fluid, plasma and urine at 2hour, 48 hour, 72 hour and 168 hour following its administration in order to study the efficacy of the MMC-CH as a drug delivery system. There were minimal toxicities in born marrow, liver, and gastrointestinal system after intraperitoneal MMC-CH administration. The data of this study suggested that MMC-CH may have a somewhat more beneficial effect than surgery alone when administered in optimal dose and schedules, but the MMC concentration of the peritoneal fluid was not sufficient to eradicate remnant cancer cells, and effective duration of maintenance was only below 24 hours in the peritoneal fluid and plasma.
