비활성 기체 Ar, Kr 및 Xe의 in-registry??out-of-registry의 구조 상전이 현상으로부터 흡착제 표면에서의 분자간 상호작용을 고찰하였다. 단분자층 완성 영역인 Knee band 부근에서의 제2분자층의 기여를 구하였다. 제1분자층은 lattice gas로 보고 quasi-chemical theory를, 제2분자층은 2차원 기체로 보고 virial 상태방정식을 적용하였다. 이 결과로부터 제2분자층의 기여와 단분자층 용량을 구하였다. 이 단분자층 용량에 분자 단면적을 곱하여 흡착제 표면적을 구하였다. In this work, intermolecular interaction on surface of adsorbent have been theoretically studied as considering the phenomenon of in-registry??out-of-registry structual phase transition. The contributions of the 2nd layer in knee band region of completing monolayer have been calculated. For the 1st layer assumed as a lattice gas, quasi-chemical theory and for the 2nd layer assumed as a two-dimensional gas, virial equation of state are applied. The isotherm which combines two isotherms, the 1st layer and the 2nd layer isotherm, is calculated and is compared with experimental isotherm. And then the contribution of the 2nd layer and monolayer capacity are calculated. The surface area of adsorbent is calculated using calculated monolayer capacity and cross sectional area of an adsorbed molecule.

Die-upset Nd_(15)Fe_(77)B_8 자석의 자기적 특성에 미치는 제조조건 및 Ga 첨가의 영향

이경섭,김용성,박현순,서수정 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.1

The effects of process parameters and Ga addition on the magnetic properties of die-upset Nd_15Fe_77B_6 magnets were studied. The intrinsic coercivity (_iH_C) was decreased because of grain coarsening by die-upset process. The Remanence (4πM_r) was varied by the extend of crystalline anisotropy. The alignment of c axis depend on the temperature and speed of die-upset process. The coercivity loss by die upsetting was reduced with Ga addition.

Many studies have been published on the human health effects of carbosulfan toxicity. Carbosulfan used as an insecticide can produce an irritating and allergenic effect when acting on the skin. In this study, a sensitization test on albino guinea pigs and intradermal reactivity and occular irritation test on albino rabbits were carried out with carbosulfan. Signs of acute skin inflammation appeared along with the clinical symptom of chronic dermatosis caused by the solution irritating characteristics. Moreover, carbosulfan showed severe eye irritation with conjuctival redness and severe opacity on cornea. Preventive measures should involve workers' obligatory instructions on the noxious impact on human skin and strict observance of industrial safety rules.

Ozone is an important atmospheric pollutant that is occurred in tropospheric chemical process and it also affects the human health and plants. For a correct application of abatement strategies for ozone, it is necessary to understand the factors that control atmospheric ozone removal by dry deposition processes. The present study investigates the numerical simulation of the dry deposition velocity(V_(d)) obtained from PNU/DEM(Pusan National University Deposition Model). PNU/DEM includes seasonal categories, meteorological factors, surface properties and land-use types and proposes for and accurate numerical computation. And, this study examines the ability of the PNU/DEM to compute V_(d) of ozone over water surfaces and evaluates PNU/DEM by comparing its estimated V_(d) to past observed V_(d) over water. The parametrization was found to yield V_(d) values generally in good agreement with the observations for the deciduous forest and the coniferous forest. Ozone is removed slowly at wet surface of water due to its low water solubility. Therefore V_(d) values over water were lower than V_(d) values over the other surfaces. Comparison of PNU/DEM simulated V_(d) values to observations of ozone V_(d) that have been reported in the literature implies that PNU/DEM produces realistic results.

Background: The sigmoid septum described an anatomical variation in the contour of the left ventricular outlet. It is related to degenerative change with aging. We observed clinical significance of sigmoid septum in Korean. Methods: Echocardiographic examination was performed in 434 patients. Sigmoid septum is defined as discrete bulging of the proximal interventricular septum with that thickness is greater than 1.3cm or the thickness is grater 1.5 times than adjacent mid interventricular septum in apical 3 chamber view. Result: The incidence of patient with sigmoid septum(septum patient) is 24.8% (male 8.4%, female 16.3%) . The incidence increases with age and is more common in women. The patients with sigmoid septum were compared with targeted groups, there was no significant difference in blood pressure between them, but in height and weight, the former were lower. (p<001, p<03). In the patients with sigmoid septum, weight and the surface area of a body have an opposite correlation with increase of age (p<03, r=-0.34) (p<04, r=-0.31) , but no decrease of height was found according to age increase (p=0.47, r=-0.11) The main reason patients with sigmoid septum ask echocardiolography and its clinical symptoms were abnormal results of previous electrocardiography and/or usual chest pain. Compared with control group, interventricular septal thickness is larger in septum patients (p<001). The thickness of interventricular septum located in subaortic left ventricular outflow tract is 1.6±0.3cm. There is another web like structure that continued from interventricualr septum to anterior free wall of left ventricle and the width is 1.6±0.4cm. A sign of insignificant obstruction due to left ventricular outflow was observed from three sigmoid septum patients. Conculusion: Septum patient is largely found in older age group and the body weight and body surface area are lower than control group. The body weight and body surface area are opposite correlation with age. So sigmoid septum is considered as structural change by weight reduction with aging. It is assumed that septum patients are related with asymptomatic ischemia because they have more abnormal ECG finding such as T wave inversion on precordial leads or standard leads, nonspecific ST-T change, LBBB etc. Sigmoid septum is not only proximal interventricular septal bludging but also another web like structure continuing to anterior wall of left ventricle.

이경섭,박현순,서수정 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.2

The effects of Al additions and heat treatment on the magnetic properties of Nd-Fe-B sintered magnets were studied. As the Al content was increased, remanence was reduced and coercivity was increased. Also, as these sintered mangets were heat treated at 600℃, remanence(B_r) and intrinsic coercivity(_iH_c) were increased. In spite of coercivity was increased by the Al addition, maximum energy product(BH)_max was reduced. the highest energy product of 27.9MGOe was obtained in the Nd_15Fe_77B_8 magnet which was heat treated at 600℃.

A catalog system is defined as an electronic commerce entity that provides a common web-based storefront to a group of merchants. Customers access the "catalog system" web site to browse catalogs of merchant companies that deliver goods and services. This enables customers to search for goods, compare prices at a central location instead of visiting multiple dislocated web sites. The catalog system model is attractive to small business for which the benefits of maintaining an individual web site may never justify the overhead. The catalog system maintains a database containing catalog information for each merchant. A existing catalog system don's have a standard catalog system. This paper presents an implementation model, that uses Extensible Markup Language(XML) and JAVA to overcome the standard problem. We propose goods catalog system with XML, and JAVA.
