The Characteristic Research of Multi-Phase Interleaving Buck-Converter for High Efficiency and Low Ripple for Green Car or Light System

고재수,조은석,이용근 한국전시산업융합연구원 2014 한국과학예술융합학회 Vol.18 No.-

A step-down non-isolated Buck converter is acommon and basic topology in the field. Weanalyzed the Characteristic of Multiphase InterleavedBuck Converter in DCM(Discontinuous CurrentMode) and CCM(Continuous Current Mode) for lawripple and high efficiency1). Multiphase buckconverter has more advantages than other topology. Input current of converter is divided into eachconverters because of the structure. it has featuresof decreasing input current ripple and increasingefficiency of converter. So we can reduce the sizeof Capacitor and Inductor2). It means that the sizeof system is also reduced3). The Time ReverseRecovery loss of diode was also affected4)5), theTRR loss was confirmed to be negligible in the120kHz 8 Phase case despite the CCM situation. Inthis study, the effects of the loss factors wereanalyzed on the efficiency of the multiphaseinterleaving buck converter in DCM and CCM, andit would be helpful to design a more efficientconverter by effectively controlling the factors ofeach loss. At least, we tested the performance ofthe analyzed system with PSpice.

성령의 증거

고재수 高神大學校 1986 論文集 Vol.14 No.-

성경에 대한 성령의 증거에 관해 웨스트민스터 신앙고백은 세가지를 언급하고 있다. 곧 교회의 증거, 성경 자체의 증거, 성령 증거이다. 이 중 교회의 증거는 도입적인 것이다. 대부분의 사람들은 교회의 인도를 받아 성경의 권위를 알게 된다. 교회의 증거의 결과로써 우리는 성경을 고귀하게 볼 수 있다는 것이다. 하지만 고귀함 그 자체는 성경을 하나님의 말씀으로 인정하는 것이 되지는 못한다. 또한 교회의 증거가 그러한 고귀함을 가져다 주는 일은, 가능하겠지만 그 결과까지 확실히 보장하지는 못한다. 성경 자체 증거로는 성경이 하나님의 말씀인 사실을 보여주기 위해 여러가지의 매우 무게있는 논증들을 제시하고 있음을 본다. 그러나 어떤 이유 때문에 그 자체 증거는 우리의 확신을 이루지 못한다. 성경이 하나님의 말씀이라는 확신은 성령의 증거만이 생기게 할 수 있다.

성령으로의 세례를 지적하는 본문들에 대한 주석적 고찰

고재수 高神大學校 1987 論文集 Vol.15 No.-

성령으로의 세례라는 문제는 20세기 이전에는 많이 토론된 문제가 아닌 것 같다. 그것은 성령론 자체가 무시되었다는 뜻이 아니다. 개혁신학에만 제한시켜 보더라도 칼빈은 기독교강요 네 권 중 셋째 권에서 성령론을 다루었고 그래서 성령의 신학자란 별명을 얻었다.

To study the differentiating cytomorphological features of Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) using fine needle aspiration cytology (FNAC), cytomorphological features of 16 patients with HL (n=8) or ALCL (n=8) were analyzed. In the initial cytological diagnosis prior to biopsy, HLs were properly diagnosed in 4 out of 8 cases (4 HL, 2 atypical, 2 benign), whereas all ALCL were diagnosed as malignancies. However, correct diagnosis of non-Hodgkin lymphoma (NHL) was made in only two ALCL patients (2 NHL, 1 HL, 1 sarcoma, 4 malignancy without specific type). Overall, the percentage of large abnormal cells ranged from 30% to 90% in ALCL except for one case, whereas it was less than 5% in all 8 HL. A spectrum of atypical cells was more characteristic of ALCL. In contrast, HL showed an sharp difference between reactive lymphoid cells and neoplastic ones (bimorphic pattern). Moreover, the emergence of kidney-shaped abnormal cells or wreath-like multinucleated cells was helpful in diagnosing ALCL. The combination of thesefeatures would be useful in differentiating HL and ALCL. Nevertheless, these two types of lymphomas cannot be definitely distinguished based on cytomorphological features alone. Therefore, the aim of FNAC would be to suggest a specific diagnosis and indicate the need for a biopsy.

다발성 골수종 1예의 체액 세포학적 소견

A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear melding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known. 저자들은 비교적 접할 기회가 흔치 않은 횡문근육종의 체액 세포학 3예를 경험하였기에 그 임상 소견과 함께 세포학적 소견을 간결히 기술하였다. 제 1예는 흉벽에 다형 횡문근육종이 있는 환자의 늑막 삼출액 소견으로서, 세포들은 느슨한 군집을 형성하거나 개별적으로 흩어져서 도말되었고 핵은 다형성이 심하였으며 다핵을 가지는 세포도 관찰되었고 과염색상을 보였다. 횡문근육종의 특이 소견인 가로무늬는 관찰되지 않았고 세포질은 미세 공포형이었다. 나머지 2예는 구강 원발성 및 원발 병소를 알수 없는 배형 횡문근육종으로서 이들의 늑막 삼출세포학적 소견은 서로 유사하였다. 군집을 형성하거나 개별적으로 흩어진 세포들은 작고 둥근 세포들로서 이들은 미미한 세포질과 과염색상의 핵을 가지고 있었으며 소 세포 암종에서 관찰되는 염주형 배열 또는 주물 현상은 인정되지 않았다. 육종의 체액 세포학은 원발 병소및 아형이 알려진 경우에 진단적이라고 여겨진다.

A total of 362 bile samples from 104 patients with evidence of biliary tract obstruction were submitted for diagnostic cytology from January, 1989 to April, 1991. The patients were classified based on the obstructive cause, and the cytologic results were reviewed. 298 of the specimens were from patients with intrabiliary malignant structure, and 17 were from patients with extrabiliary malignant compression or benign biliary obstruction. Bile cytology was positive for carcinoma in 42 samples from patients with intrabiliary malignant stricture, and the diagnostic sensitivity was 14%. There were no false positive cases. We concluded that the cause of low sensitivity was degenerative change of cell due to prolonged sampling time. What is noteworthy was the high prevalence of Clonorchis sinensis eggs, being detected in 25 patients with intrabiliary malignancy, supporting the association between clonorchiasis and biliary tree malignancy.

"Atypical Squamous Cells of Undetermined Significance"의 질적 분류와 조직 소견과의 비교

고재수,정진행,이승숙,조경자,Koh, Jae-Soo,Chung, Jin-Haeng,Lee, Seung-Sook,Cho, Kyung-Ja 대한세포병리학회 1999 대한세포병리학회지 Vol.10 No.1

To evaluate whether different qualifications of a cytologic diagnosis of "atypical squamous cells of undetermined significance(ASCUS)" predict a greater or lesser likelihood of tissue diagnosis of uterine cervix, we compared different cytologic qualifications of ASCUS with the tissue diagnosis. One hundred twenty-two consecutive Papanicolaou smears showing ASCUS in women who had undergone cervical biopsy within nearest 30 days were collected. The 122 smears were qualified as "favor reactive"(25%), "favor low grade squamous intraepithelial lesion (LSIL)"(24%), "favor squamous intraepithelial lesion(SIL)"(16%), "favor high grade squamous intraepithelial lesion(HSIL)"(16%), and "not otherwise specified"(19%). Squamous intraepithelial or invasive lesion was pathologically confirmed by cervical biopsy in 13%, of the "favor reactive", 27% in "favor LSIL", 70% in "favor SIL", 75%, in "favor HSIL", and 35% in "not otherwise specified" smears. There were significant associations between the favor reactive smear and the benign biopsy finding and between the favor SIL smear and the biopsy shewing a squamous intraepithelial or more severe lesion. Nevertheless, most of favor LSIL smears exhibit reactive process in tissue biopsy. Conclusively, qualified ASCUS stratifies women Into different risk groups for SIL. The cytopathologist should make the cytologic diagnosis of "ASCUS, favor LSIL" circumspectly.
