Liquid-phase methanol synthesis via methyl formate using coal-derived syngas was carried out in a bench-scale(diameter 173 mm and dispersion height 1200 mm) slurry bubble column reactor(SBCR) Under the condition of 180˚. 61 atm, 30 L/min, H2/CO=2 and a slurry mixture of 2 kg of copper chromite and 0.5 kg of KOCH3 suspended in 14 L of methanol, the per pass conversions of syngas is 6 %, maximum concentration of methyl formate 3.088 mol% and maximum synthesis, rate of methanol 0.8 gmole/kg · hr. It is a significant evidence that copper chromite powder as heterogeneous catalyst didn't active for the hydrogenolysis of methyl formate to methanol, resulting copper chromite powder was not efficiently suspended in a slurry mixture. To enhance the hydrogenolysis of methyl formate in liquid-phase methanol synthesis process, the designed SBCR have need to use the higher specific gravity solvent and/or decrease the catalyst particle size.
In this report, we provide the focus on suggesting a method of estimating and measurement of CBM(Customer Behavior Model). Through the use of internet, a new trend of business for e-CRM on B2C Web Site known as EC has emerged. The purpose of this study is to identify the relationship between the customers of a shopping mall and CBM characteristics. It can be used to gain a better understanding of customers. from this we can determine trends, and so refine business toward customer's needs and target new products to particular customer groups. Result shows that there is a significant relationship between the customers pattern of shopping mall and CBM, CVM(Customer Visit Model).
Allergic rhinitis is characterized by rhinorrhea, sneezing and nasal obstruction. Allergic rhinitis increases because of developments of diagnostic techniqhe, environmental change, especially industrialization. Recently people have studied on allergic rhinitis. We studied 107 allergic rhinitis patients with SBJ from June. 2002 to December, 2002. There was a significant effect of SBJ on allergic rhinitis. So, we suggested the clinical effect of SBJ on allergic rhinitis.
Recently there have been growing disputes between neighboring local governments over jurisdictional rights or property rights of ocean resources in Korean coastal waters. The reasons for the disputes come mainly from the increasing interests by local governments that begin to see the oceans as the source of resources and wealth. The maritime dispute is more complicated and sticky than the inland ones, and requires not only socio-economical but political approach, therefore sometimes demanding a plenty of time and endeavor. Also coastal states that have suffered from maritime boundary problems have different issues under the different environment and historical background. For Korea, as the maritime boundary issue has very recently soared to the surface, though it was latent for the period as long as 20 years, we have just taken steps toward an institutional approach on it, seemingly more to go to reach an agreeable resolutions to the disputes. This paper highlighted the issues surrounding the maritime boundary on the sea surrounding Korean peninsular after addressing the current situation of the boundary disputes. It will help explore and assess the possible solutions to the boundary conflicts over the lateral boundary between local governments.
The quantitative evaluation method of the safety management cost was suggested to prevent a gas accident as a major industrial accident. In a gas governor station, process risk assessments such as the fault tree analysis(FTA) and the consequence analysis were performed. Based on process risk assessments, potential accident costs were estimated and the cost-benefit analysis(CBA) was performed. From the cost-benefit analysis for five classification items of safety management cost, the order of the cost/benefit ratio was estimated.
A study on the Byungtae Ron(病能論) of the So Moon(素問), one of the classic book of oriental medicine, was carried out analytically for the right comments. The principal ideas obtained summarized as follows; Neng(能) is similar to tae(態) in the pronunciation and the meaning of a chinese character. Byungtae(病能) means the state of the symptoms and the pulse condition of the diseases, etc. It deals with ethological factor, mechanism of disease, the condition of an illness, method of diagnosis, rule of treatment, technique of treatment of seven diseases and taking this seven diseases as a example, mainly discuss the technique and significance of clinical observation and the pathogenesis and condition of an illness, so It named Byungtaeron(病能論) In this chapter it shows we can grasp condition of illness well only if we classify the pathogenesis and condition of an illness in details. this viewpoint provides the foundation of development in oriental diagnostics. It places emphasis on pulse feeling in this chapter, so it describes pulse condition of various kinds of diseases in details. It also presents how to compare pulse feeling like comparison between Inyoungmaek(人迎脈, arterial carotid communes, the pulsation of which is easily felt beside Adam's apple) and Ch'onkumaek(寸口脈, the radial artery on the wrist where the pulse is routinely taken for diagnosis), between right and left Ch'onkumaek(寸口脈), between Yangmyungsangdong (陽明常動) and Taeyangbudong(太陽不動), Soyangbudong(少陽不動), etc. In this chapter it explains pulse feeling occupies a high position in the diagnosis of diseases in Huangdi's internal Classic(黃帝內經) period and the technique of pulse feeling is already plentiful and minute. In this chapter it presents Tongbyungyichi(同病異治, to apply different methods of treatment to the same kind of disease) theory, taking tangible syndromes as examples. this is prominent viewpoint of determination of treatment based on the differentiation of symptoms and signs and much influence development of later ages' medicine. On the ground of oriental medical theory, it may bring about different symptoms in the same disease according to stage of disease, the seasons, the regions, the constitution of patient, therefore surely adopt different technique of treatment. this differentiation of symptoms and signs is an important character in oriental medicine.
Iridology, developed more than 100 years ago, is the diagnosis of medical conditions through noting irregularities of the pigmentation in the iris The purpose of this study is to compare interrelation between CVA, hypertension family history and cardio-renal connective tissue in Iris Constitution through iris constitution examination. The subjects consist of 114 patients who were examined in Iris Constitution at Chonju Oriental Medicine Hospital attached to Wonkwang Univ. from September. 1st. 2000 to August. 31th. 2002. 1. In the distribution of Iris Constitution, among of 79cases, There are neurogenic type 13cases, abdominal connective tissue weakness constitution 31 cases, cardio-renal connective tissue weakness constitution 6 cases, cholesterol 7 cases and others 22 case in control group. 2. There are familial history of CVA and hypertention 32 cases, no familial history of CVA and hypertention1 3 cases, in 35cases of experimental group. These results imply that there is meaningfulness of interrelation between cardio-renal connective tissue weakness constitution and CVA, hypertention.
Most of process data control have been designed under the assumption that there are independence between observed data. However, it has been difficult to apply the traditional method to real-time data because they are autocorrelated, and they are not norm
