An objective of this paper is to discuss the didactical contracts which have been conceptualized by Brousseau. He modelled mathematics instruction as a game. In such game, didactical contracts existed as its own hidden rules which teacher and student should obey Brousseau introduced it to reveal certain hidden rules which regulates mathematics instruction. Those rules are implicit and reciprocal. In particular, it is not revealed until students break. He defined didactical contracts as teacher's behaviour and corresponding students 'behaviour in order to define it operationally. He he did not define it in psychological and epistemological dimension. But it is necessary to discuss teacher's belief system and epistemology, since teacher's behaviour in instruction is affected by them. He also did not discuss fully teacher's breaking of didactical contracts.

An increase in the number of retiring experienced pilots as well as drastic graying of new pilots will raise the problems on deepening imbalance of supply and demand of pilots over the next 7 years, which could entail fatal problems for the safety of harbour pilotage. In this study, the improvement plan of legal system to ease imbalance between supply and demand of pilots and help secure more experienced pilots has been proposed. A current state survey and analysis, statistical analysis, questionnaire survey on foreign countries, in-depth consultation with experts, etc., were all carried out to support this research. The conclusions of this study are, firstly, to propose an amendment that the minimum requirement of 5 years of seagoing service as a master to sit for the pilot exam should be relaxed to 2 years(which must include at least 1 year of master's seagoing service within the most recent 5 years) but the minimum requirement of 1 year of pilotage service should be reinforced to 1 year and 6 months to obtain a higher class of pilot certificate. Secondly, it is proposed that an amendment offering an additional 1 point per year over the minimum period of 2 years of seagoing service as a master should be added, with a maximum of 10 points in order to rationalize the additional incentive point system. In order to secure experienced pilots and resolve the legal conflict between the certificate revalidation system and the retirement system, it is also proposed that an amendment be passed revoking the retirement system and limiting the validity of any new certificates only to 68 years of age when issuing or revalidating a certificate, if an applicant is over a certain age. Promotional work, such as collecting opinions from interested parties and generating positive public awareness, should be carried out in the future. It will also be necessary to conduct a study on the training pilot exam system.

I. Identity of Yeonsegeuk as total arts. The purpose of the thesis is to arrange the identy of Yeonsegeuk(Kino-Drama) which is theatre or film. The process of study is tried to discuss on the aethetic of Yeonsegeuk. II. Appearance of Yeonsegeuk and negative disputation of yeonsegeuk The first imported Yeonsegeuk from Japanese in Korea is made by the group of Mizuno Ganggetsu(水野觀月) on Oct. 16. 1915 at Pusan and also to run in Seoul at Hwanggeumgwan. The first of Korean Yeonsegeuk is by Kim, Dosan, a leader of Singeukjwa(theare group) on Oct. 27. 1919 at Danseongsa. Before the liberation of Korea from Japan all made korean Yeonsegeuk are 28 works. III. Dramatic form of Yeonsegeuk I study on the relation between Yeonsegeuik and Sinpageuik(new theatre of modern drama in 1920's). I find that Yeonsegeuik admitted the thechnics of the Sinpageuik and the contents. If We think that the theatre is synthetic art which genealize all arts, we can insist that the Yeonsegeuk is valued the total art as new performance to comply with film art to theatre. Conclusionly Yeonsegeuk is called 'Expanded Theatre' as the new performance which must be dicussed in the view of total art. VI. Discussion on the the aethetic of Yeonsegeuk When we compare the structure of film with the structure of theatre, we can't find a diffrent element between the structure of two art in art semiotic. But we find a fact that film art has special elements in mechanics character which are camera working and motage. These technics influence on the audience's mind. It is different point between Japan and Korean's Kino-drama and Germany's that is to admit the aethetic of total art or not. V. Yeonsegeuk as new performance During Korean modern times Kino-drama was first a kind of total art with stage and screen. But it is regretable that Kino-drama didn't have the background of theory which discourse on the comprehension of total art. As the result Kino-drama bring the confusion of argument that Kino-drama is total art or expanded theatre. This confusion will be disputed on film art as performing arts or future art as expanded film and total art.
