The purpose of the study is to enhance the teaching competence for pre-service elementary teacher by using DGE in order to enhance SMK and PCK for them. To do this, we investigated the initial SMK and PCK for 23 pre-service elementary teachers, the reality of implementation activity of DGE and the change of SMK and PCK after quest activity by DGE. As results, 3 pre-service elementary teachers made errors which are misunderstanding a general angle as special angle, an excessive jump of logic and a circulation logic in the aspect of an initial SMK. In the aspect of contents of PCK, most of pre-service elementary teachers proposed teaching focused on the character using in the problem solving. And most of pre-service elementary teachers proposed teaching methods which are based on explanation, measurement and material manipulation. The reality of implementation activity of DGE was classified 4 cases which are a difficulty in understanding the concept of dynamics and embodying in DGE, an obsession about construction of $75^{\circ}$ and generalization, a difficulty in interpreting 'folding activity' mathematically and a good implementation activity. After quest activity by DGE, the case which is misunderstanding a general angle as special angle could be improved, but the others are not. And after quest activity by DGE, most of pre-service elementary teachers still proposed teaching focused on the character using in the problem solving in the aspect of contents of PCK, and some of pre-service elementary teachers added only teaching methods which are involving visual confirmation by GSP. From these results, we could extract some pedagogical implications helping pre-service teachers to reinforce SMK and PCK by DGE.

Despite the importance of sexual life of the aged, it is almost disregarded due to the Confucius value system and bias. The common people's view on the sex of the aged was clearly demonstrated by their attitude toward a movie entitled "I love it though I might die" which was determined "18 Age over"being awareness of its explicit sexual intercourse and several lied on the discussion. For this reason, the sex of the aged is clandestinely revealed and uses to receive publicity for sexual assault for children, sexual crime, and illegal prostitution in parks. And social atmosphere that prevents open discussion of the sexof the aged increases in the number of suffering aged in reality, and it causes the decrease of life quality of them. In this circumstance, cartoon contents can be perfectly used for sex education for them. Entertainment character and genre character of cartoon contents can deliver the understanding of sex rather voluntarily and easily to the aged and it can be used as a tool to motivate by indirect experience and to enhance efficient understanding.

Alternaria sesami, A. sesamicola, A. tenuis, A. longissima, Cercospora sesami, Cephalosporium sp., Corynespora cassiicola, Fusarium equiseti, F. moniliforme, F. oxysporum, F. semitectum, Macrophomina phaseolina and Myrothecium roridum were detected from 40 seed samples of sesame. A sesami, A. sesamicola, A. tenuis and C. cassiicola were the predominant fungi. Except C. cassiicola, all fungi were almost completly reduced and wiped out the infection by pretreatment with chlorine. Plating components also indicate that C. cassiicola was well-established infections. Seedborne infection of C. cussiicola caused heavy seed rot and seedling mortality. Detailed description has been given on the habit character of C. cassiicola under stereoscopic microscope and the variation in colony character and spore morphology have been taken into account. In inoculation experiments, C. cassiicola produced severe leaf and stem spots and blights on sesame plants resulted in ultimate death of the plants. A. sesami, A. sesamicola A. longissima and C. sesami also produced mild to severe leaf spotting and leaf blight when suspension of their conidia were sprayed on to plants. In soil inoculation experiments, F. oxysporum and M. phaseolina were the most pathogenic causing seed rot and seedling blight.

This study gives information for the enterprise to map out a positive marketing strategy and facilitate a new product development by researching and analyzing the specific character of the high income woman-brackets. In order to do that, based upon the materials of the National Statistical office, I made a selection of the high income brackets, subdividing their scholastic ability into four serfs. The subject of the study was the women from twenties to sixties among customers of a high class dress shop in Taejeon. I made up 600 questionnaires for them. using 441 of these for the statistical analysis and making available the correlation analysis, the primary factor analysis, and $X^2$-test. This study is classified into the type of women customers purchasing clothes who are the high-income brackets. Intended to study a special quality of purchasing according to income. 1. The purchasing manner of the high-income brackets customers is exposed the luxurious vain purchasing manner, the rational reasonable manner, and idiosyncrasy individual manner in order 1) The consumer of the high-income brackets in general prefer to a high class clothes. In the contrast, low-income brackets prefer to rational reasonable consumption in spending money on clothes. 2) The favorite consumption manner of the high income brackets is the luxurious vain purchasing manner. This consumption values the more symbolic means the things show than owing the goods. 2. The higher standard of education and younger tends to be high in the luxurious, vain purchasing. 3. The unreasonable purchasing show an high irrelation at the impulse buying arid self-satisfaction. 4. Self-satisfaction shows the highest interrelation than any other variations in the concern of clothes. 5. The symbolic images which exerts an influence upon purchasing manner are the notable elements of constituting as growing older. 6. The high standard of education prefers to the rational resonable purchasing, but on the other hand shows a high rate at the unreasonable individual purchasing manner.

This paper treated what are congressional records which are one of core fields of national records and what kind of significant records they have. The characteristics of "substantive records" of the institution among public records are as follows: firstly, their contents depend on the inherent function of the institution; secondly, their types differ by the character of basic unit(member); thirdly, their sources are determined by the character of institution. Starting from the above points of view, the contents, characteristics, main sources, and types by sources of congressional records were presented. They are summarized as follows. In Chapter 2, the substantial records, which document the intrinsic function of congress on the basis of analyses of inherent function and structural uniqueness of congress have natures of which the contents are "legislative records", "oversight records", and "political activity records" starting from the inherency of congress as the people's representation. The typical natures of congress records are related with the specialty that the basic unit of congress structure is an individual congressman as an indepent national institution and congress is a council of these congressmen. Firstly, the records of congressmen as basic member of congress are the national records with the type of personal records. Secondly, "council records" produced by the council (commettee and main conference), which have evidencial and informative value for decision making through the process of investigating, discussing and voting bill and policy (item) of the basis for national management, are very special kind of records, such as item records, decision records, journal records, and congress assistant records. Because congressmen and councils composing congress have an equal inter-relationship in the structure of congress, the main sources of congress records are an individual congressman and all the councils. In chapter 3, the contents and sorts of main records are discribed, centering around congressmen and councils as the main sources of congress records. In chapter 4, the management of records of congressmen is issued as an urgent subject for the management of congress records, instead of conclusions.

The purpose of this study is to clarify the meaning and characteristics of re-organized shortform contents, which is centered on media companies to edit and service existing broadcast content. For this, KBS, MBC, SBS, JTBC, and tvN's entire drama videos and representative entertainment programs opened on the Naver TV platform from 2014 to 2021 were selected for analysis and a synchronic and diachronic approach was conducted at the same time. As a result of the analysis, quantitative and qualitative expansion was made, with the number and form of videos provided by both dramas and entertainment programs diversifying from a synchronic approach. In particular, in the case of special videos, the meaning as independent content was also strengthened, such as sequencing centered on characters, themes, and materials. It was confirmed that thumbnails and titles were also formalized as tags as paratexts that act as curation for searches. From a diachronic point of view, it was found that re-organized shortform contents is considered to be character-oriented contents and independent viewing context through comparison with real-time views and original videos. This study is significant as an attempt to capture the meaning and phase change of shortform contents, which was considered incidental.
