Obstructive sleep apnea syndrome(OSAS) is a complex sleep disorder characterized by intermittent apnea secondary to sleep-induced obstruction of the upper airway. It occurs because of an airway obstruction anywhere between the trachea and the oronasal apparatus. The hallmark of OSAS is snoring, which is caused by vibration of the tissues of the pharynx as the airway narrows. The consequences of OSAS have focused on excessive daytime sleepiness resulting from sleep fragmentation and the cardiovascular derangements producing hypertension and arrhythmias. The primary method of controlling OSAS has been surgery. The current surgical procedures used for OSAS are tracheostomy, tonsillectomy, nasal septoplasty, uvulopalatopharyngoplasty, anterior mandibular osteotomy with hyoid myotomy and suspension, and maxillary, mandibular and hyoid advancement. We report a case of OSAS that was improved by genial advancement with infrahyoid myotomy and suspension. The patient was objectively documented by polysomnography, cephalometric analysis, and physical examination before the surgical procedure. The patient underwent genial advancement with infrahyoid myotomy and suspension. Patient had a good response from surgery.

김재진,Kim, Jaejin 디지털산업정보학회 2016 디지털산업정보학회논문지 Vol.12 No.2

In this paper presents a low power algorithm using a feasible cluster generation method considered glitch. The proposed algorithm is a method for reducing power consumption of a given circuit. The algorithm consists of a feasible cluster generation process and glitches removal process. So that glitches are not generated for the node to which the switching operation occurs most frequently in order to reduce the power consumption is a method for generating a feasible cluster. A feasible cluster generation process consisted of a node value set, dividing the node, the node aligned with the feasible cluster generation. A feasible cluster generation procedure is produced from the highest number of nodes in the output. When exceeding the number of OR-terms of the inputs of the selected node CLB prevents the signal path is varied by the evenly divided. If there are nodes with the same number of outputs selected by the first highest number of nodes in the input produces a feasible cluster. Glitch removal process removes glitches through the path balancing in the same manner as [5]. Experimental results were compared with the proposed algorithm [5]. Number of blocks has been increased by 5%, the power consumption was reduced by 3%.

시간 제약 조건하에서 면적을 고려한 효율적인 CPLD 기술 매핑

김재진,김희석,Kim, Jae-Jin,Kim, Hui-Seok 대한전자공학회 2001 電子工學會論文誌-SD (Semiconductor and devices) Vol.38 No.1

본 논문에서는 시간제약 조건하에서 면적을 고려한 CPLD 기술매핑 알고리즘을 제안한다. 본 기술매핑 알고리즘은 주어진 EDIF나 부울식의 불린 네트워크에서 궤환을 검출한 후 궤환이 있는 변수를 임시 입력변수로 분리하여 조합논리회로로 구성한다. 구성된 회로는 DAG 형식으로 표현한다. DAG에서 각 노드를 검색한 후, 출력 에지의 수가 2이상인 노드는 분할하지 않고 노드만을 복제(replication)하여 팬 아웃 프리트리로 재구성한다. 이러한 구성 방법은 주어진 시간 조건 안에서 기존의 CPLD 기술 매핑 알고리즘으로 제안된 TEMPLA보다 적은 면적으로 회로를 구현하고, TMCPLD의 단점인 전체 수행 시간을 개선하기 위한 것이다. 시간제약 조건과 소자의 지연시간을 이용하여 그래프 분할이 가능한 다단의 수를 결정한다. 각 노드가 가지고 있는 OR 텀수를 비용으로 하는 초기비용과 노드 병합 후 생성될 OR 텀수인 전체비용을 계산하여 CPLD를 구성하고 있는 CLB의 OR텀수보다 비용이 초과되지 않는 노드를 병합하여 매핑 가능한 클러스터를 구성한다. 매핑 가능 클러스터들 중에서 가장 짧은 다단의 수를 갖는 클러스터들을 선택하여 그래프 분할을 수행한다. 분할된 클러스터들은 콜랍싱(collapsing)을 통해 노드들을 병합하고, 주어진 소자의 CLB안에 있는 OR텀 개수에 맞게 빈 패킹(Bin packing)을 수행하였다. 본 논문에서 제안한 기술매핑 알고리즘을 MCNC 논리합성 벤치마크 회로들에 적용하여 실험한 결과 DDMAP에 비해 62.6%의 논리블록의 수가 감소되었고, TEMPLA에 비해 17.6% 감소되었다. TMCPLD와의 결과 비교는 조합논리 회로의 5개 회로만을 비교한 결과 4.7% 감소되었다. 이와같은 실험결과는 CPLD를 이용한 기술매핑에 상당한 효율성을 제공할 것으로 기대된다. In this paper, we propose a new technology mapping algorithm for CPLD consider area under time constraint(TMFCPLD). This technology mapping algorithm detect feedbacks from boolean networks, then variables that have feedback are replaced to temporary variables. Creating the temporary variables transform sequential circuit to combinational circuit. The transformed circuits are represented to DAG. After traversing all nodes in DAG, the nodes that have output edges more than two are replicated and reconstructed to fanout free tree. This method is for reason to reduce area and improve total run time of circuits by TEMPLA proposed previously. Using time constraints and delay time of device, the number of graph partitionable multi-level is decided. Initial cost of each node are the number of OR-terms that it have. Among mappable clusters, clusters of which the number of multi-level is least is selected, and the graph is partitioned. Several nodes in partitioned clusters are merged by collapsing, and are fitted to the number of OR-terms in a given CLB by bin packing. Proposed algorithm have been applied to MCNC logic synthesis benchmark circuits, and have reduced the number of CLBs by 62.2% than those of DDMAP. And reduced the number of CLBs by 17.6% than those of TEMPLA, and reduced the number of CLBs by 4.7% than those of TMCPLD. This results will give much efficiency to technology mapping for CPLDs.

This study was carried out to determine the lethal water temperature and lethal concentrations of phnol and lead on Anodonta woodiana collected from Bam islet in Han river, Seoul, Korea. Lethal temperature$(LT_{48,50})$ on a woodiana was $37-38^{\circ}C$, and lethal concentrations$(LC_{50})$ of phenol and lead nitate were 1200 ppm and 220 ppm, respectively.

Organized Hematoma in the Maxillary Sinus

김재진,Kim, Jae-Jin Korean Association of Maxillofacial Plastic and Re 2010 Maxillofacial Plastic Reconstructive Surgery Vol.32 No.5

Organized hematoma of the maxillary sinus is a rare, nonneoplastic benign lesion with locally destructive behavior that may mimic a malignancy. Clinically, symptoms do not usually occur while the lesion remains localized to the maxillary sinus. Because there is gradual enlargement of the lesion causing erosion and displacement of the adjacent bony structures, symptoms such as epistaxis, cheek swelling, nasal obstruc-tion, headache, and exophthalmos become manifest. Radiologically, unilateral cases are much more fre-quent than bilateral, and Waters' view shows complete opacity of the expanded maxillary sinus and some masses. CT scan shows a large heterogeneous enhancing mass causing considerable expansion of the max-illary sinus with bony erosion. On MR imaging, the mass usually has a variable signal intensity on T1- and T2- weighted images, ranging from low to high. After contrast administration, discrete areas of enhance-ment are present within the mass. Although the disease is essentially benign and nonneoplastic, differen-tial diagnosis from neoplastic disease including malignancy both clinically and radiologically has been always problematic. Accurate preoperative diagnosis of organized hematoma of the maxillary sinus is important to avoid unnecessary extensive surgery, because this condition is curative with a simple, conservative surgical approach and rarely recur. Organized hematoma of the maxillary sinus should be included in the differential diagnosis when patients have recurrent epistaxis, slow-growing mass of the cheek, nasal obstruction, and expansile mass in the maxillary sinus. A 33-year-old man was referred to the department of oral and maxillofacial surgery with a three-month history of slowly growing painful swelling of the left cheek. The mass of the maxillary sinus was resected by a Caldwell-Luc approach. Histopahtoly showed only a fibous encapsulated organized hematoma. To our knowledge, organized hematoma of the maxillary sinus has not been previously described in the Korean literature of the oral and maxillofacial surgery. We report a case of organized hematoma of the maxillary sinus presenting with an enlarging maxillary sinus mass.

김재진,윤충모,Kim, Jae-Jin,Yun, Choong-Mo 한국정보통신학회 2006 한국정보통신학회논문지 Vol.10 No.12

본 논문에서는 CPLD 조건식에 위 한 RTL 바인딩을 제안하였다. HDL로 기술된 회로에 대해 스케줄링을 수행한 후 모듈 연산 간격을 고려하여 합당한 모듈을 선택하여 할당을 수행한다. 할당을 수행한 후 주어진 조건식에 맞도록 CPLD를 선정한다. 할당된 결과의 모듈을 CPLD 내부의 CLB의 맞도록 부울식을 분할하고, 최적의 CLB를 사용하여 회로를 구현할 수 있는 바인딩 알고리즘을 제안하였다. 16 비트 FIR 필터로 실험한 결과 알고리즘을 적용하기 전보다 작은 크기의 CPLD로 회로 구현이 가능하였으며, 가산기의 경우 알고리즘을 적용하지 않았을 때 내부 사용율은 8.45%이었으나 알고리즘 적용한 결과 61.88%로 내부 사용율이 증가되는 결과를 나타내었다. In this paper, a RTL binding technique for CPLD constraint is proposed. Allocation processing selected module consider the module calculation after scheduling process for circuit by HDL. Select CPLD for constrain after allocation. A Boolean equation is partitioned for CLB by allocated modules. The proposed binding algorithm is description using optimum CLB within a CPLD. The proposed algorithm is examined by using 16 bit FIR filter. In the case that applicate the algorithm, the experiments results show reduction in used CLB.

Bithyniidae과 패류 치설의 미세구조에 관한 연구

김재진,최임순,임승섭,한규웅,Kim, Jae-Jin,Choe, Rim-Soon,Lim, Seung-Sub,Hahn, Kyu-Woong,Claus, Meier Brook 한국현미경학회 1988 Applied microscopy Vol.18 No.2

The radulae of six species of bithyniid snails, Bithynia striatula, B. tentaculate, B. siamensis, B. leachi, Gabbia misella and G. australis, were observed by SEM. The radular formula of all the bithyniids studied was 2 : 1 : 1 : 1 : 2. The all teeth were multicuspid and the central teeth had numerous basal denticles. The mesocones of the central and lateral teeth were spade or arrow-head shape. The mesocones of the central teeth and the lateral teeth of B. leachi, G. misella and G. australis were slightly larger than the other cusps in contrast of those of the other species. Number of cusp was varied by the specimen and the species.

BIPV에서 Flexible PV의 각도 조절을 이용한 MPPT 추적 알고리즘 연구

김재진,Kim, Jaejin 디지털산업정보학회 2017 디지털산업정보학회논문지 Vol.13 No.3

In this paper presents the MPPT tracking algorithm using angle control of flexible PV in BIPV. The proposed algorithm is based on MPPT tracking algorithm for curtain wall using flexible PV. It is an algorithm to find optimal power generation condition by controlling the angle of flexible PV using the air layer of window. The angle of flexible PV tests the power generation by separating the center of flexible PV into the interior angle in the interior direction and the external angle in the center of flexible PV. When the angle of flexible PV was used as interior angle, the generation amount was increased by 15.79% and increased by 8.45% compared with the external angle. MPPT tracking is performed on the generation amount of the interior angle which has the most power after comparing the generation amount according to the bending shape of the flexible PV. This algorithm can be the most efficient method for the curtain wall using flexible PV because the bending pattern with the greatest amount of power generation may be different because the environment of the building applying the curtain wall is different.

김재진,Kim, Jae-Jin 배재대학교 자연과학연구소 1998 自然科學論文集 Vol.10 No.1

1995년 10월부터 1996년 9월까지 인천 화수 부두 주변 해역의 저서생물상을 조사하였다. 다모류가 모든 정점에서 4계절 모두 우점하였다. 그 다음으로 연체동물과 갑각류가 많이 출현하였으며 극피동물은 닻해삼 1종(Protankyra bidentata)만이 출현하였다. 정점 1에서는 오염지표종으로 알려진 Capitella capitata가 적은 수나마 출현하여 다른 정점에 비하여 오염이 다소 진행된 것으로 생각되며, 정점2와 3에서는 Heteromastus sp.가 다량 출현하여, 유기물 유입이 많은 곳으로 추정된다. The survey of the macrobenthic animals near Hwasoo wharf, Inchon, Korea was carried out during October, 1995 through September, 1996. Polychaeta was the most dominant taxons were Mollusca and Crustacea. Only one species of Echinomermata, Protankyra bidentata, was collected. Capitella capitata collected from site 1 indicates that the site was more polluted, and Heteromasmus sp. collected from sites 2 and 3 suggests that these sites were polluted with organic materials.
