In this note, we show that the ${\omega}$-limit mapping is continuous and the Lipschitz constants vary continuously if the flow (x, ${\pi}$) is Lipschitz stable. Moreover we analyse the ${\omega}$-limit sets under the generalized locally Lipschitz stable flows.

Let X,Y be connected, locally connected, semilocally simply connected and $f,g : X \to Y$ be a pair of maps. We find an upper bound of the Reidemeister number R(f,g) by using the regular coverig spaces.

The studyies on physico-chemical factors and phytoplankton at the 3 rivers in the Taejon city were conducted from November 1997 to May 1998. The Results were as floows; In the water quality, the down streams were generally worse than the upper streams. Water temperature was varied from 2.4$^{\circ}C$ to 23.$0^{\circ}C$; DO from 1.80mg/$\ell$ to 17.6mg/$\ell$ ; pH from 4.7 to 10.4 ; BOD from 0.78mg/$\ell$ to 8.80mg/$\ell$ ; COD from 0.32mg/$\ell$ to 8.26mg/$\ell$ ; SS from 2.0mg/$\ell$ to 43.0mg/$\ell$ ; total phosphate was from 0.001mg/$\ell$ to 0.709mg/$\ell$ ; total nitrogen 0.01mg/$\ell$ to 11.69mg/$\ell$. In phytoplankton species, they were identified as total 191 taxa composed of 8 classes, 18 orders, 35 families, 74 genera, 152 species, 35 varieties and 4 forms. The dominant species were Synedra ulna in Taejon-chon, Diatomavulgare in Yudong-chon, Oscillatioria princeps, Scenedesmus qadricauda, Synedra ulna, and Diatom vulgare in Gap-chon. Standing crops of phytoplankton were from 2,076 cells/$m\ell$ to 97,356 cells/$m\ell$

The survey was conducted to investigate the consumption aspects of commercial kimchi and the future pattern of kimchi consumption. The college students(473) were randomly selected from six universities in Taejon. Ninety seven percent of students had taken the commercial kimchi. They chose kimchi manufactured by the famous company(62.4%), merchant in market(16.9%), and agricultural corporation(14.4%). In purchasing the commercial kimchi, qualty(76.0%) was considered as the most important factor and then price(13.1%), brand name(5.1%). The main reason for disliking commercial kimchi was indicated as 'different taste from home-made' by the male and 'additives added in kimchi' by the female(p<0.01). The maintenance of aging condition was believed the most essential factor to increase the consumption of commercial kimchi. Two thirds of the subjects anticipated to take home-made kimchi after marriage. Half of them replied to want to take kimchi made by traditional method, even though to buy the sauce for kimchi-making sold in market. More female students were willing to purcase the sauce for kimchi-making than the male(p<0.01).
