자외선 조사경화법에 의해 양이온화된 양모/면(55/45) 혼방직물의 반응성 염료에 의한 일욕 균염 염색

In order to achieve single-bath level dyeing of wool/cotton blend fabric, the blend fabric was cationized by photografting of cationic monomers before dyeing. Low water content of the fabric was beneficial in terms of the grafting yield of cationic agent onto cotton. Cationization effect resulted from the grafting of the cotton component rather than the wool due to the low grafting yield of the wool. Level dyeing was accomplished by dyeing cationized blend fabric using a simple dyebath of either cotton reactive dye or wool reactive dye. The degree of level dyeing of the blend was assessed by P% which was calculated from the K/S values after soaping of the pure wool and cotton.

[3-(Methacryloylamino)propyl]trimethylammonium chloride의 연속식 광그라프트에 의한 PET 직물의 양이온화

장진호,손정아,Jang, Jin-Ho,Son, Jung-A 한국섬유공학회 2007 한국섬유공학회지 Vol.44 No.6

PET fabrics were photografted under continuous UV irradiation with [3-(methacryloylarnino)propyl]trimethylammonium chloride (MAPTA) and 4-benzoylbenzyltrimethyl ammonium chloride (BTC) as a cationic monomer and a photoiniotiator, respectively. It was found that the optimal grafting was obtained when PET fabrics were irradiated with a D-bulb in a UV energy of $35\;J/cm^2$, on which were padded with an aqueous formulation of 3% photoinitiator concentration in advance. The surface of the grafted PET was characterized using FT-IR (ATR), ESCA, zeta potential measurement, water retention value (WRV). ATR and ESCA analysis, indicating significant alterations on chemical structure and atomic composition of increasing nitrogen content with increasing grafting yield. The zeta potentials changed from -4.9 mV for the untreated PET up to +16.7 mV for the grafted sample. The photografted fabrics showed an higher water absorbancy as indicated by the increased water retention value compared to the untreated PET. SEM images showed that PET surface was covered with the grafted cationic polymer.

Superior Vena Cava Syndrome Due to Mediastinal Tuberculous Lymphadenitis

장진호,전두수,김윤성,조우현,여혜주 대한가정의학회 2017 Korean Journal of Family Medicine Vol.38 No.3

Superior vena cava (SVC) syndrome refers to a medical emergency resulting from compression of the SVC. It re-quires early diagnosis and treatment, and is usually caused by malignant tumors; rarely, mediastinal tuberculous lymphadenitis can cause SVC syndrome. Here, we present a case study of an immunocompetent 61-year-old wom-an who presented with acute onset SVC syndrome and was diagnosed with tuberculous lymphadenitis on thora-cotomy; the symptoms resolved with anti-tuberculosis therapy. This unusual case highlights the importance of the differential diagnosis in patients presenting with acute onset SVC syndrome; a timely diagnosis and appropriate treatment lead to complete recovery.

곰소만 조간대 퇴적물의 장기적 변화

장진호,류상옥,조영조 한국지구과학회 2007 韓國地球科學會誌 Vol.28 No.3

In Gomso Bay, on the west coast of Korea, the surface sediments sampled in 1991 and 2006 were analysed toidentify the long-term variations of tidal flat sediments. Silt and clay contents have decreased in the bay-mouth tidal flatsparticular, the clay contents of the tidal flats in 2006 were relatively low when compared to those of both tidal flatsadjacent to other semi-enclosed bays and those of the tidal flats in 1991. The variations of textural compositions in thetidal flat sediments have led to changes of the sedimentary facies. It indicates that the changes must have been made bythe changes of hydrodynamic conditions impacted by human activities, such as the construction of sea-walls, landreclamation, structures of farms constructed compactly near the low water line, and the Saemangeum dyke constructed inthe northern part of the area where this research was conducted..........

근사 곡률을 이용한 3차원 치아 모델의 기하학적 특징 검출

장진호,유관희,Jang, Jin-Ho,Yoo, Kwan-Hee 한국정보처리학회 2003 정보처리학회논문지 A Vol.10 No.2

최근 몇 년간 의학 분야에서는 인체의 해부학적 구조를 컴퓨터 그래픽스 기술을 통해 컴퓨터로 재구성하려는 많은 시도가 있었다. 이러한 시도는 치의학 분야에서도 이루어져 왔으며, 여러 분야에 응용되고 있다. 예를 들어, 치과 자료의 3차원 가시화와 측정, 임플란트 식립 위치 찾기, 보철학에서 인공치아 재건을 위한 곡면 재구성과 교정학에서 치아의 재위치 등이 그 예이다. 본 논문에서는 이들 치의학 응용 분야에서 가장 중요하게 사용되고 있는 교두, 능선, 열구 및 피트와 같은 치아의 기하학적인 특징을 검출하기 위한 기법을 제시한다. 제안된 방법은 석고 모형의 3차원 입력으로 만들어진 3차원 치아 모델에서 계산된 근사 곡률에 기초한다. 제안된 방법을 사용하여 검출된 결과는 기하학적인 특징을 보여주며, 제안한 방법과 다른 기존의 방법의 가시적 비교를 통해, 제안한 방법이 좀더 정확한 기하학적인 특징을 검출하는데 유용하게 사용될 수 있음을 알았다. In the latest medical world, the attempt of reconstructing anatomical human body system using computer graphics technology awakes people's interests. Actually, this trial has been made in dentistry too. There are a lot of practicable technology fields using computer graphics in dentistry For example, 3D visualization and measurement of dental data, detection of implant location, surface reconstruction for restoring artificial teeth in prostheses and relocation of teeth in orthodontics can be applied. In this paper, we propose methods for definitely detecting the geometric features of teeth such as cusp, ridge, fissure and pit, which have been used as most important characteristics in dental applications. The proposed methods are based on the approximate curvatures that are measured on a 3D tooth model made by scanning an impression. We also give examples of the geometric features detected by using the proposed methods. Comparing to other traditional methods visually, the methods are very useful in detecting more accurate geometric features.

조간대 퇴적물의 계절적 집적양상과 보존: 한국 서해안의 곰소만

장진호,최진용,Chang, Jin-Ho,Choi, Jin-Yong 한국해양학회 1998 바다 Vol.3 No.3

우리나라서해안의 곰소만 조간대에서 조간대 퇴적층의 형성 및 보존과정을 규명하기 위해 지형, 퇴적물의 입도, 집적률 등의 계절적 변화를 조사하였다. 조간대를 횡단하는 측선에 대해 계절별로 수준측량한 결과, 겨울과 태풍 때 중부 조간대의 조간대사주(intertidal sand shoal)와 상부 조간대의 쉐니어(chenier)가 육지방향으로 크게 이동하였고, 특히 태풍 때에는 중 하부 조간대가 광범위하게 침식되었다. 그러나 여름에는 조간대사주와 쉐니어의 이동이 제한되었고, 중부 조간대의 상부역과 상부 조간대에 펄이 퇴적되었다. 퇴적물의 계절적 입도변화는 주로 중부 조간대의 상부역에서 크게 나타났으며, 대체로 5.5 ${\phi}$에서 모드를 갖는 펄질 퇴적물의 집적(여름)과 침식(겨울, 태풍)에 의해 야기되었다. 해저면에서 기준면까지의 깊이를 2 개월 간격으로 측정한 결과, 상부 조간대에서는 연중 지속적으로 퇴적이 이루어지고 겨울보다 여름에 집적률이 높은 반면, 중부 조간대에서는 여름보다 겨울에 퇴적이 우세하고 태풍 때 간헐적으로 침식되는 특징을 보였다. 그리고 하부 조간대는 주로 겨울에 퇴적되었고 여름과 태풍 때 침식되었다. 캔코아를 통해 퇴적층의 보존모습을 분석한 결과, 위의 계절변화 양상이 대체로 코아의 상부층에만 제한적으로 보존되었고, 하부층으로 갈수록 폭풍 퇴적층의 출현빈도가 증가하였다. 이상의 결과들에 기초하여 볼 때, 곰소만 조간대층의 많은 부분이 겨울 폭풍 또는 간헐적 태풍에 의해 재구성된 폭풍 퇴적층일 가능성이 높은 것으로 판단된다. Seasonal changes of topography, sediment grain size and accumulation rate in the Gomso-Bay tidal flat, west coast of Korea, have been studied in order to understand the seasonal accumulation pattern and preservation potential of the tidal-flat sediments. Seasonal levelings across the tidal flat show that the landward movement of both intertidal sand shoals and cheniers accelerates during the winter and typhoon periods, but it almost stops in summer when mud deposition is instead predominant at the middle and upper tidal flats. Seasonal variations of mean grain size were largest on the upper part of middle tidal flat where summer mud layers were eroded during the winter and typhoon periods. Measurements of accumulation depths from sea floor to basal plate reveal that accumulation rates were seasonally controlled according to the elevation of tidal-flat surface. The upper tidal flat where the accumulation rate of summer was generally higher than that of winter was characterized by a continuous deposition throughout the entire year, whereas in the middle tidal flat, sediment accumulations were concentrated in winter relative to summer and were intermittently eroded by typhoons. The lower tidal flat were deposited mostly in winter and eroded during summer typhoons. Can cores taken across the tidal flat reveal that sand-mud interlayers resulting from such seasonal changes of energy regime are preserved only in the upper part of the deposits and generally replaced by storm layers downcore. Based on above results, it is suggested that the storm deposits by winter storms and typhoons would consist of the major part of the Gomso-Bay sediments.

Four kinds of polarizing film were prepared by two coloration methods of dipping and dyeing using either iodine or dye as a dichroic colorant. The optical properties of the polarizing films were compared at various concentrations of dichroic colorants and draw ratios. While iodine of low substantivity to PVA film showed little dependence of colorant content on the coloration methods, in the dye-type polarizing film dyeing method caused higher surface and bulk colorant contents than dipping method due to higher substantivity of the dichroic direct dye. However surface dichroic colorants on the film exhibited higher effectiveness in terms of observed optical properties compared with bulk dichroic colorants in the PVA film. While dye-type polarizing film showed excellent resistance to heat and humidity compared to iodine-type, coloration method did not influence significantly the optical durability of dye-type polarizing film under hot and humid condition.
