Objective: The purpose of this study was to evaluate clinical efficacy of fetal fibronectin as a marker to predictor of preterm labor. Materials & Methods: The study group consisted of sixty-eight healthy pregnant women, at gestational age between 24 and 36 weeks, who visited our department with vaginal discharge from April, 1995 to December, 1997. For comparison, we divided all of the pregnant women into two groups by the result of ROM-Check^®, positive groups(N=21) and negative groups(N=47). When preterm labor appeared, 50mg of ritodrine hydrochloride(Yutopar^®) mixed I liter of 5% dextrose solution was administered slowly intravenously. Results: 1) The gestational age at delivery and the interval time from admission to delivery in the positive groups were significantly shorter than those of the negative groups(p<0.05). 2) The positive groups had significantly lower birth weight and Apgar scores than the negative groups(p<0.05). 3) Among the negative groups, in case of tocolytics administration, the interval time from admission to delivery significantly delayed more than that time in case of no tocolytics administration(p<0.05). Conclusions: The detection of the fetal fibronectin in vaginal discharge had a useful method as a predictor of preterm labor. Tocolytics was more effective in the negative groups than in the positive groups.

The Object of Study is to look for the Relationship Types between Advertiser and Advertising-Agency in Korea advertising Industry. This study show how the Relationship Types between Advertiser and Advertising Agency are classfied, and what is the highest continuous intention and satisfaction among those Types. And this shows that what is different from search step to evalution step and that what are the characters according to types? And that the Relationship Types between them in advertising industry are as followings according to Bradach and Eccels(1989), and powell's studies. On the first phase of th Relationship Types, when Relationship Types among companies adopt to advertising industry, Hierarachical Relationship Types is the same as the In-house Agency Type. And transactional Type and embedded type are the same the independent type. On second phase of the relationship-involving process, except contents apart from korea advertising industry's, in the search step, the Michell model(1995) was adopted except business environment. Relationship-Involving process has three steps. First step is search step, second me is relationship-making step, third one is evaluation step. The analysis results have the implicatoins like below table. First in the search step between advertiser and AD-Agency, places emphasis on the cooperation with the agent which has similar size and fame, in the case of In-house agency relationship type, policy and team work development is place emphasis on sharing professtional value and criteria. Second, in the relation-making level at in-house agency relationship pride in the team outcomes and understanding on the work dependence are very important, while at the independent agency relationship periodic review system, mutual strong leadership are important. Third, in relation-making level at in independent agent relationship agent's control ability. creative standard, marketing advice suggestion, advertising effect and sales performance are critical points, while, at service level, most are low. Therefore, to keep continuous long-term trust and improve the degree of satisfaction between advertiser and advertising agency in korea advertising industry, advertiser should change from hierachical relationship to their parterners relationship about AD-Agency in the past time. Accordingly, from now on AD-Agency should play major roles on the creative standard, marketing advice to the adveriser. the marketing specialist employment, advertising effect and sales performance. which has been dependent on the advertiger until now.

Recently, the need for supporting time varying information in databases has been recognized for quite some time.Thus, attention has been focused on Temporal Databases, representing an enterprise over time.Many authors have proposed numerous schemes to satisfy this need by incorporating one or two time attributes in the database. In this paper, We have introduced to this field, and surveyed a taxonomy of time and implementation issues which are the versioning methods, storage structures, and it's performance evaluation, and suggested the versioning method, storage structure, and approach to the development of a model for DBMS with time and revision-history supporting. And we'll expend this paper to design and develop the relational DBMS with time and revision history supporting.

The vapor-liquid equilibria at high pressure are predicted by using Peng-Robinson's equation of state. The interaction and size parameters included in the equation of state are obtained by optimization based on the principle of maximum likelihood. The optimal size parameter ηij is nearly equal to unity for 100 binary systems composed of carbon dioxide-hydrocarbon, methane-hydrocarbon and hydrocarbon-hydrocarbon, which are extremely unsymmetric systems. This fact means that it is not necessary to introduce the size parameter(ηij) into the equation of state. The interaction parameter ηij depends irregularly on temperature for all the binary systems and it is more sensible to the error of experimental variables than the temperature of system. More accurate observed date are, therefore, needed to investigate the temperature dependence on the interaction parameter.

This investigation was operated by the author when he was staying as a visiting scholar at UCLA from Apr. to Jun. 2002. The subject of this investigation is the university students of Korean Language courses of UCLA and USC, High school students of Korean schools in LA area, the parents of them and the teachers of Korean schools. The total amount of investigated is 813 people, the type of investigation is questionnaire. Almost of young Korean heritage generation think about Korean people, Korean language and Korean society very affirmatively and almost of the parents think that Korean education for their sons and daughters is very necessary. By this investigation, 58.8% of Korean heritage high school and university students answered that Korean language is important language in the USA, More than 80% of respondent answered that Korean society and Korean education in the USA are developing. The average age of starting Korean language learning of these students are 2.1 - 4.2. The first place of their learning Korean is their home(68.1%), the Korean school (21.4%). The mose important reason of university students who are learning Korean is 'for communicating with family(27.2%) and that of high school students are 'as a matter of course because I'm Korean'(29.4%). Almost of Korean heritage parents think that their children must be educated with Korean Language. And they are spending less than 100 dollars for their children's Korean language learning per month. 90% of Korean language teachers of Korean school in LA was engaged as a teacher without any examination. It was pointed out that the qualifications for Korean language teaching, i.e. newspaper, internet, PCs, must be improved is urgent.

Orostachys malacophyllus Fischer is a plant to grow on the tiled roof of the old house, and on the rock in the mountain. And the chemical compositions of the plant have not known yet. But it has transmitted to this day as a kind of medical plant from remote antiquity. Sometimes, it is used in the folk remedies for the treatment of the malignant diseases. This study was attempted to investigate the effects of water extract or water fraction on the Na-K-ATPase activity, on the renal functions, and on the contractility of the cardiac and intestinal muscles. The results obtained were summarized as follows: 1. The activity of Na-K-ATPase purified from the outer medulla of pig was increased at 0. 01%, and was decreased at 0.1% of the water extract. 2. In the study of the renal functions of rabbits, urine volume, glomerular filtration rate (GFR), and renal plasmaflow (RPF) were decreased by water extract, and their decreased phenomena were continued after infusion of physiological saline 3. The free water clearance of rabbit kidneys was decreased significantly by water extract. 4. The contractilities of the isolated ventricular muscles of turtles were increased, and of muscle strips of mice intestine were decreased by the addition of water extract. 5. The contractilities of the isolated ventricular muscles of turtles were decreased, and of the muscle strips of mice intestine were increased by the addition of water fraction from alcohol extract. 6. The increased contractility of the cardiac or intestinal muscle was inhibited significantly by the addition of the mixed solution with verapamil.
