WO₃계 NO_(x)센서의 검지 특성과 바인더 첨가 효과
양종인,한상도,김일진,손영목,임한조 경북대학교 센서기술연구소 1997 센서技術學術大會論文集 Vol.8 No.1
The effects of various binderssuch as PVA, silica sol and alumina on the sensing characteristics of TiO_(2) (4 wt. %)-doped WO_(3)-based NO_(x). sensors were investigated. The sensor with PVA (polyvinyl alcohol) binder showed an improved sensitivity (R_(gas)/R_(air)- in NO_(x) 15 ppm = 375), response time and cross-sensitivity (selectivity) for interference gases (CO, SO_(2), CH_(4), C_(3)H_(8)). It could also be operated at a lower consumption power (about 1.6W at 180℃). The sensors with silica sol and alumina binders showed a decreased sensitivity (R_(gas)/R_(air) in NO_(x) 15 ppm = 63 and 31, respectively) for NO_(x) gas sensing, but they showed an improved cross-sensitivity, response and recovery time (1 -2 min. and 1 min., respectively) than the sensor fabricated without binder.

Objective : Our purpose of this study is to evaluate the effectiveness of the transcatheter arterial embolization for the management of abnormal uterine bleeding. Materials and Methods : 14 patients with massive or recurrent uterine bleeding underwent percutaneous transcatheter arterial embolization between February 2003 and September 2004. We reviewed 14 cases of uterine artery or internal iliac artery embolization using gelfoam or PVA particles. Results : Good management of uterine bleeding was achieved in 13 of 14(93%) cases. The cause of abnormal uterine bleeding was myoma(5 case), post D & E bleeding(3), acquired vascular malformation(3), pseudoaneurysm(1), adenomyosis(1), and endometrial hyperplasia(1). Conclusion : Transcatheter artery embolization is an effective and life-saving procedure in massive or recurrent uterine bleeding. Early diagnosis and prompt transcatheter arterial embolization is a useful mangement of uterine bleeding.

This study was performed to investigate: The ecological difference of two ecotypes "Seushan (northern) and "Cheju(southern)" The effect of temperature (low. high. alternative) and long day treatments on the growth and bulb formation in two ecotypes Translocation of growth regulators and contents of total sugars in garlic plants Identification of isozyme existing in garlic plants by the electrophoretic method. The results are summarized as follows: 1. The experiment of temperature and long day treatments. Sprouting and early growth of the southern type were accelerated by low iemperature treatment but those of long day treatment were not affected. In plant height and leaf sheath length. the southern type was increased more than the northern type until March 20 and the plants that were treated with low temperature were increased considerably as compared with the control There was no difference in the total leaf numbers between two ecotypes but low temperature treatment romoted those as compared to the control. 2. Ecological experiment of two regions The plant height of the southern type was accelerated until March 25 i n Cheju and March 10 in Suweon. but the plant height of the northern type was promoted after April 20. The growth of leaf length and leaf sheath lentth showed no dlfference durting winter. but after March 10 the southern type was increased in Suweon and Cheju. there was no difference in clove number and bulb weight within the regions and seeding time. but those of the southern type were increased as compared with the northern type 3 Analysis of sugar Low temperature treatment tended to increase concetrations of sugar as compard with control and the difference between cultivats was clear Friictosan was increased as the plants grew. especially at the later period of the whole growth with ever): treatment 4 Bioassay at growth regulators Af Rf 0.5-0.6 and Rf 0.4-0.5 Glbgberellin-like substances were detected from the leaf and leaf sheath of northern type and inhibitors were detected at Rf 0.7-0.9 While 5. The change of Isozyme patterns It was noted that the isozyme patterns were similar between two ecotypes in peroxidase. There was no difference at the bands which means acid phosphatase in two types. There were three or four bands which showed Malate dehydrogenase. but also showed the similar tendency according to the cultivars and every parts.

In the most cases we analyze a single time series without explicitly using information contained in the related time series In many forecasting situations, other events will systematically influence the series to be forecasted(the dependent variables), and therefore, there is need to go beyond a univariate forecasting model. Thus, we must build a forecasting model that incorporates more than one time series and introduces explicitly the dynamic characteristics of the system. Such a model in called a multiple time series model or transfer function model. The purpose of this study is to develop the stochastic stream water quality model of Puyea station in Keum river system. The performance of the multiplicative ARIMA model and the multiple input-single output transfer function model were examined through comparisons between the historical and generated monthly dissolved oxygen series. The result reveal that the multiple input-single output model lead to teh improved accuracy.

Fe-Mn-Si계 합금의 형상기억능에 미치는 변형온도 및 training 효과
강후원,한재익,장우양,강조원 조선대학교 생명과학연구소 2000 生産技術硏究 Vol.22 No.1
The shape memory effect is resulted from the reverse motion of Shockley partial dislocations which change εmartensite back to austenite. In Fe-Mn-Si alloys, the shape memory effect is obtained by the reverse transformation of stress-induced E martensite during heating. The reversibility of the motion of partial dislocations will not lead to a complete recovery. There are many factors influencing the shape memory effect like as alloy composition, Neel temperature, transformation temperature, applied stress and strain, annealing and quenching temperature, deformation and recovery annealing temperature etc. In this paper, shape memory effect by training treatment(cold working- annealing) and deformation temperature between -20℃ and 200℃ with amount of strain was improved in Fe-l5Mn-5Cr-10Co-3Si alloys Training treatment suppresses slip deformation and lower the stress for induced εmartensite transformation through introducing the stacking faults which can act as nucleation embryo for εmartensite.

Anisakiasis refers to parasitic infestation by nematode larvae that belongs to the subfamily Anisakinae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish. While gastric anisakiasis is commonly diagnosed by endoscopic technique, intestinal anisakiasis is rare because it is less common and the clinical and radiologic features are poorly understood. The authors report a case of human anisakiasis involving the ileocecal valve in 62-year-old man who had the history of eating raw cuttlefish.

Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

Rice Stickiness Measurements with Consideration of Contact Area
Han Jo Park,Jung Hwa Yang,Han Dong Jang,Seung Ju Lee 한국산업식품공학회 2017 학술대회 및 심포지엄 Vol.2017 No.04
Cooked rice stickiness is one of the critical quality factors. A new data processing method from a simple experiment detaching after compressing cooked rice on a platform of texture analyzer was developed to create a new instrumental parameter which represents a true stickiness from sensory evaluation. The proposed idea was that the contact area produced by compressing with a fixed magnitude of force should vary with the sample’s consistency, ending up distorting the stickiness simply measured as the detaching force. Therefore, a corrected stickiness was defined by considering the contact area and converting to a stress (force/area) from just a force. The contact area could be estimated from the volume, density and thickness of samples. Even the compression force was converted to a corrected compression force by dividing by the contact area. The new corrected parameters turned out well to show a much better agreement with the sensorial stickiness than the uncorrected stickiness.
