Using the Duff and Noland`s method, the annual ring growth patterns of the red pine in the natural stands were examined at two locations; Seocheon, Chungnam-do where the stand had been infested with the pine needle gall midge, Thecodiplosis japonensis, during the years from 1975 to 1978, and Hongsong, Chungnam-do where had been no incidence of the insect damage. The results obtained are as follows: 1) With the normal red pine of 13 year old, the growth pattern in the oblique sequence indicates that the annual growth rates are maximum at the few terminal internodes, and decrease gradually with the downward internodes. Such characteristic of the growth pattern is not clear in the horizontal sequence of annual rings. 2) The indications of the radial growth reduction of the pine tree due to the pine gall midge infestation could be examined with any of three series at the crown level internodes; horizontal, vertical and oblique series. For the basal internodes, however, the horizontal series appeared to be inadequate for the analysis of the damage impact because it seemed to be masked by various factors other than direct effects of the damage. 3) Of the three ways of radial growth analyses, oblique sequence seems to be the most usefull, especially for the detection of the impact on growth caused by incipient or light infestation.

Some aspects of the change in the rate of gall formation on the red pine, Pinus densiflora Siebold et Zuccarini, by the pine needle gall midge, Thecodiplosis japonensis Uchida et Inouye, were investigated at the coastal area in Chung Nam-Do from 1977 to 1982, and were analyzed with the nationwide survey data for 2 years from 1980 to 1981. The results obtained were as follows; the gall formation rate in several areas was compared between two consecutive generations. Four regression equations were established, with X as the gall formation rate in N year and Y as that in (N+1) year: 1) Y=11.2+1.15X (r=0.833) for the stands facing north on the phase of insect population increase, 2) Y=14.3+0.82X (r=0.739) for the stands facing south on the phase of population increase, 3) Y=7.3+0.46X (r=0.478) for stands facing north on the phase of population decrease and 4) Y=11.4+0.19X (r=0.086) for stands facing south on the phase of population decrease. After invasion of the pine needle gall midge into a red pine forest, gall formation rate increased for 6 consecutive generations and then decreased to low level within a period of another 6 years.

The biological magnification and the uptake patterns of lead, copper and zinc in Persicaria thunbergii naturally grown at the areas of the rivers were investigated. The biological magnification values of lead, copper and zinc in the plant were 82.4∼254.6㎍g^1, 284.6∼688.4㎍g^1 and 635.5∼1979.4㎍g^1 individually. The tendency of the biological magnification in the each organ of the plant was as follows : Pb an Zn were increased of stem<leaf<root but Cu was leaf<stem<root. The amount of heavy metals in the plant were in the order of Pb<Cu<Zn. The magnification force of heavy metals in the plant were 13.2 times in Pb, 73.2 times in Cu and 58.7 times in Zn to compare with the content of heavy metals in the habitat soil and have a tendency to follow the content of those in the habitat soil but not proportional. In the mixture medium applied heavy metals, Cu induced the Zn depiciency in the plant. Concludly, the P. thunbergii was the excellent plant which removed the heavy metals from the soil and water of the habitat.

The effects of the pine needle gall midge, Thecodiplosis japonensis, on the growth of the Korean red pine, Pinus densiflora, were examined for the natural forest stands at nine locations: Seocheon-gun, Boryong-gun, and Hongseong-gun in Chooncheongnam-do, where consequence of the infestation had been different. To estimate the economic threshold level of the pine needle gall midge, the growth impacts due to the insect were examined with terminal shoot growth, and cambial growth by analyzing the growth horizontally and vertically. The results obtained are as follows: 1) In general, the growth impacts of the red pine trees were significant for the five consecutive years since damage had occurred, and its maximum retardation was shown in the second and the third years. 2) Simultaneous retardation occurred in both terminal and cambial growth of the tree, probably due to cumulative characteristics of the feeding behaviour. 3) Strong correlation was found between terminal and cambial growth of Korean red pine and this was true for the trees infested by pine needle gall midge, Thus retardation in cambial growth due to the insect may be estimated with that in terminal growth. 4) Infestation was greater on slope facing north than south even though the history of the infestation had been similar. 5) The stem volume of 13-year-old, infested Korean red pine was reduced by more than 75-85%, compared to same aged, uninfected pine in yield table. Thus, much longer period is required to recover the normal growth.

The exhibition and convention industries, which are recognized as industrial hub linked with many relational industries. It is important to prevent a excessive competition for convention centers among districts and to gain some benefit fairly. Each convention center needs a lot of convention to held in it`s district. In order to obtain many conventions to held in Korea for many convention center, convention bureau has to manage the processes to attract convention with many collaborators using the convention hub-network system. We should, therefore, pay attention to construction of the convention Hub-Network system to activate the convention industries in the district. We lay out the critical design for three functions of the convention Hub-Network system using UML. Finally we show the demonstrative web pages that explain critical three functions.

We suggested new extended Technology Acceptance Model(TAM) and test various theoretical research hypotheses relating to mobile application. This study examined the acceptance factors of mobile applications focused on external variables such as the perceived risk and two-side network effects, the characteristics of mobile media, user innovation and social influence. The proposed model was empirically tested using data collected from a survey of mobile application users. The results of hypothesis testing are as follows. First, the characteristics of mobile media positively influence perceived ease of use and usefulness of mobile application users. Second, perceived risk negatively influences on perceived usefulness and value attitude of mobile application users. Third, two-sided network effects negatively influence on perceived purchase risk. Fourth, perceived purchase risk was negatively influenced by social influence. The results of study will provide practical implications on the mobile application
