Cette $\acute{e}$tude a pour objectif de d$\acute{e}$velopper le g$\acute{e}$otourisme des $\hat{i}$les de Geomun et de Baek dans le Parc Marin National de Dadohae pour conna$\hat{i}$tre les caract$\acute{e}$ristiques de cette r$\acute{e}$gion du point de vue $\acute{e}$cologique, historique et culturel $\grave{a}$ partir de ses ressources g$\acute{e}$omorphiques et g$\acute{e}$ologiques qui ont la haute de valeur $prot{\acute{e}}g{\acute{e}}e$. Il y a plusieurs ressources g$\acute{e}$omorphiques et g$\acute{e}$ologiques sur l'$\hat{i}$le de Baek: falaise; caverne marine; tafoni; le relief li$\acute{e}$ $\grave{a}$ les roches volcaniques. Il y a aussi plusieurs ressources historiques et culturels sur les $\hat{i}$les de Go et d'Est: le cimeti$\grave{a}$r d'arm$\acute{e}$e anglaise li$\acute{e}$e $\grave{a}$ l'occupation ill$\acute{e}$gale de l'$\hat{i}$le de Geomun en 1885; le site historique de Kim Ryu(金劉) qui a enseign$\acute{e}$ les disciples de confucianisme et qui a $succ{\acute{e}}d{\acute{e}}$ au Confucius; la for$\hat{e}$t de feuillus de zone $temp{\acute{e}}r{\acute{e}}e$ sur l'$\hat{i}$le d'Ouest et la ceinture de falaise sur l'$\hat{i}$le de Baek. Une route g$\acute{e}$otouristique part de l'$\hat{i}$le d'Ouest et continue $\grave{a}$ l'$\hat{i}$le d'Est: c'est la route $\acute{e}$cologique, historique et culturel sur l'$\hat{i}$le de Geomun. L'autre route continue de la c$\hat{o}$te de l'$\hat{i}$le de Baek: c'est la route de paysages g$\acute{e}$omorphiques et g$\acute{e}$ologiques. Nous proposons des plusieurs exemples pour d$\acute{e}$velopper le g$\acute{e}$otourisme des $\hat{i}$les de Geomun et de Baek: installation de centre visiteur et de panneaux d'explication g$\acute{e}$otouristique sur le g$\acute{e}$osite central ; monitoring environmental.

In order to investigate the composition of dried layer, Porphyra yezoensis cultured at the south coast of Korea, the dried laver was analyzed separately for extractive nitrogen, free and combined amino acids, ATP and related compounds and quaternary ammonium basis using specimens collected monthly from January to April 1998. The extractive nitrogen contents of dried layer extracts were $976\~1,196\;mg/100\;g$ (on dry basis). Twenty-eight to thirty-one kinds of free amino acids were found in the dried laver extracts and their total amounts were 5,648-6,845 mg/100 g (on dry basis). The extracts were rich in free amino acids such as alanine, glutamic acid, taurine, phosphoserine and aspartic acid. Eighteen to twenty-two kinds of combined amino acids from oligopeptides were found in the extracts and their total amounts were $1,194\~1,406\;mg/100\;g$ (on dry basis). The amounts of ATP and related compounds were $111.6\~195.5\;mg/100\;g\;(3.30\~6.00{\mu}mol/g$ on dry basis). Homarine was detected in all samples but glycinebetaine, $\beta$-alaninebetaine and $\gamma$-butyrobetaine disappeared during processing, TMAO was detected in all samples but low TMA was found in some. During processing of dried layer, P. yezoensis, free amino acids, ATP and its related compounds were increased but the other constituents such as combined amino acids, TMAO and TMA and betaines were decreased in all specimens.

In order to investigate the composition of dried layer, Porphyra dentata cultured at the south coast of Korea, the dried layer was analyzed for extractive nitrogen, free amino acids, combined amino acids, ATP and its related compounds and quaternary ammonium basis, The extractive nitrogen contents of dried laver extracts were 670-1,304 mg/100 g (on dry basis). From twenty-eight to twenty-nine kinds of free amino acids were found in the dried laver extracts and their total amounts were $2,796\~6,277\;mg/100\;g$ (on dry basis). The extracts were rich in free amino acids such as alanine, taurine, glutamic acid, glutamine and phosphoserine, From eighteen to twenty-one kinds of combined amino acids were found in the extracts and their total amounts were $1,406\~2,142\;mg/100\;g$ (on dry basis). The amounts of ATP and its related compounds were $65.7\~124,7\;mg/100\;g(2.13\sim3.68{\mu}mol/g$ on dry basis), Homarine was detected in all samples but $\beta$-alaninebetaine, $\gamma$-bufobetaine and trigonelline disappeared during processing. TMAO and TMA were detected in all samples. During processing of dried layer, free amino acids, TMAO and TMA were increased but the other constituents such as combined amino acids, ATP and its related compounds and betaines were decreased in all specimens.

In order to investigate the composition and monthly variation of extractive nitrogenous components in the laver Porphyra dentata cultured at the south coast of Korea, the fresh laver was analyzed separately for the amounts of free amino acids, combined amino acids, ATP and its related compounds, and quaternary ammonium basis in fresh laver were measured. The extractive nitrogen contents of fresh laver extracts were 760~870 mg/100g (dry basis). Twenty-seven to thirty-one kinds of free amino acids were detected in the laver extracts and their total amounts were 2,404~3,966 mg/100g (on dry basis). The laver extracts showed rich in free amino acids such as alanine, taurine, glutamic acid, glutamine and aspartic acid. Sixteen to twenty-three kinds of combined amino acids were detected in the extracts and their total amounts were 1,429~2,692 mg/100g (on dry basis). Proline, glutamic acid, glycine, phosphoserine, serine were the amin combined amino acids in the extracts. The amounts of ATP and related compounds were 73.3~94.4 mg/100 g (2.04~4.43 $\mu$mol/g, on dry basis). Homarine and trigonelline were detected in all specimens but $\beta$-alaninebetaine, ${\gamma}$-butyrobetaine were found in some. Small amounts of trimethylamine were detected in all samples. Free and combined amino acids were occupying almost 90% of extractive nitrogen. Most of free and combined amino acids showed a marked monthly variation with a maximum in January and March, and a minimum in February and April. The fresh laver P. dentata did not differ much from the fresh laver P. yezoensis in qualitative com-position of extractive components, but their contents were generally low level.
