Reinforced concrete structures are damaged by material, environmental, and physical factors during service period. Also, when we designed, the stiffness of member should be increased because of unexpected overloads and decreased durability. So, recently, repair and strengthening are became a concern on reinforced concrete structure. On this study, damaged reinforced concrete member are reinforced using carbon fiber grid, new multi cumulated material. And effect of reinforcement is experimentally analyzed. First of all, material properties of carbon fiber grid, uncontracted polymer mortar, and rapidly hardening mortar are experimentally researched. And then, application is verified by shear test and attachment test with two kinds test specimen, respectively. Using five actual size RC beam (width 40cm, height 50cm, length 650cm), yield strength test and bending test are carried out. Finally, yielded five specimens are reinforced with each other methods and fracture strength test is carried out. That results are compared and analyzed to confirm the reinforcement effect.

In order to manage our house keeping and home life more scientifically and reasonably, it is certainly required to handle and manage our house ware utensils wisely. Therefore, I attempted to investigate the present condition of house ware utensils management in our country. As a result of this research I am sure we can get the approved materials about mechinized house work labor and working space research for saving house work labor, and energy consumption required in house work labor. Consequently, it can contribute to the improvement and enlightenment of our home life by showing the adequate measure against fatigue, and also the utilization of leisure time most usefully. Moreover, it may further indicate the manufacturing order of the house ware utensils according to its degree in necessity demanding at our homes. I tried hard to investigate this subject by classifying according to some different regions, such as Seoul Region, Middle Part Region, Yeungnam Region, Honam Region and Island Region. I selected in Seoul Region, Sajik-dong where most Korean old-fashioned traditional homes still remained with its own way of life. And also I selected some modern newly set up regions, such as Tongkyo-dong, Seukyo-dong, and Daekwang. Anam Mansion Apartment as a collective residential region in Seoul. In the Middle Part Region, I selected Koyang-gun and Chooncheun city and Cheungjoo city. In Yeungnam Region I selected Andong city, and Masan city. In Honam Region I selected several farm houses in Jeungup-gun and Kwangyang-gun. In Island Region I selected Jejoo city in Jejoo Island respectively. The method of my research was to select 100 homes in each region selected, and to make some questions to those people to get their direct and honest frank answers. The contents of the research were as follows: (1) Condition of Managing Kitchen Unit and Kitchen Ware Utensils (2) Condition of Managing Icebox (3) Condition of Furnishing Cooking Tools (4) Condition of Managing Measuring Utensils (5) Condition of Managing Dining Bowls and Dishes (6) Condition of Utilizing Sewing Machine (7) Condition of Furnishing Time-spending Equipments & Their Utilization (T. V., Stereo, Radio, Tape-recorder, etc.) (8) As to the Research on The Order of Degree in Its Demanding for Necessary Utensils to be Furnished in the Future Time Usage, I asked some questions making 20 different items in order of their frequency of usage. The conclusion made from the analysis is as follows: (1) As of the condition of basic kitchen facilities, both in urban and rural regions are not sufficiently furnished with the proper facilities demanding greatly of improvement in sanitary aspect. (2) It is very good to have a deep concern about the working space on the ground, however, it is desirable to study more about the utilization of the empty space as a whole virtically, too. (3) Measuring the things at their cooking time they use measuring cup and spoon in the urban homes, but in the farm village homes, only under 10% of it being used showing that there is a big difference between urban and rural life in our country. However, we must first of all maintain the scientification of kitchen life as fast as possible. (4) As of time-spending equipments, radio is the first place, and T.V. is also comparatively well prevailed all over the country now-a-days. So the most of their leisure time is being used by watching T.V. at their homes. (5) I examined about the order of degree in its necessity demanding for the necessary tools and utensils to be furnished in the future time usage carefully, and I got the following result: In Seukyodong and Anam Mansion Apartment where the house ware utensils are comparatively well furnished already, the big utensils such as electric washing machines and air conditioners are greatly demanded while in rural village homes, the cooking tools such as iceboxes and electric ricekettles and mixers are much wanted.

Due to limitations of budget and personal, the sampling was limited to the Seoul area. The research methodology involved in this survey consisted of field survey analysis of actual space, calculation of adequate storage volume, and design of layout for each type of storage. The housing survey was conducted from October 1973, to April 1974. Ninety six households in Seoul city were randomely selected according to the financial status, and dwelling types. Financial levels were classified as upper, middle and lower classes according to monthly average income of subjects. The findings are as follows : 1. The house and storage volumes were directly related to the number in the family, and their income, and dwelling type. In the case of indepenedent housing, it was found that upper class families has a monthly average income of 428,000 won, with 74.3 pyung of average dwelling area middle class, 168,000 won, with 26.5 pyung; and 2ower class, 53,000 won, with 10.3 pyung. In the case of apartment dwellings, upper class, 368,000 won with 35.4 pyung; middle class, 168,000 won with 21.6 pyung; lower class 60,000 won, with 10.2 pyung. 2. The average number of persons in the ninety six households surveyed was 6 persons at independent houses, and 4.8 persons at apartments. The rate of complex and nuclear famities in the households surveyed was tabulated 36.5 : 63.5; and the difference in the number in the family due to the levels of income and dwelling type was found to be from 0.4 to 2.4 persons. 3. The actual average storage volume per person ranged from 2.1 to 7m3 for the individual house and from 2;1 to 6.4㎥ for the apartment houses and was related to the classification of financial status which indicates almost three times difference between higher and lower classes, for storage volume. 4. The actual storage volume was from of the total dwelling volume was from 8.8 to 13.4 percent. The average storage furniture volume (chests, cabinets, etc. ) in the houses, compared with total average dwelling volume was from 9.9 to 14.7 percent. The use was 112% (overflow) at lower class dwellings while approximately 90% at others. The storage of clothing and garments required from 33.1 to 50. l% of the total volume of storage. 5. Each cycle o( clothing management (purchasing, discarding or remodeling of clothes) required 2.6 years. During longer cycles, such as up to 8 cycles (20.8 years) for general handling, the increased storage volume of clothes and graments is calculated at no more than 150% of the normal middle class starting outfit. The conclusion as follows; According to Korean life habits, the author has indicated the required quantities of clothing, bedding quilts and dinnerware for an independent middle class home. The decreasing amount of main storage volume resulting from the development of social economy and culture will come to 28% : needed clothing storage space will decrease by 10 percent, bedding by 55% and dinnerware by 23 percent in the next 10 to 20 years. Thus 285 additional space will become available for other use. The author proposes the following as adequate middle class independent house storage space: living room 1.15∼3.2㎥ per household; clothing & garments, 1.51㎥ per person, bedding, 0.9㎥ per person; kitchen Cabinet, 1.7㎥ per household; midcelloneous storage 5.7㎥ per household; food storage, 5.7㎥ per household. On this basis, the author sketches proposals for each storage unit and, finally, has prepared some sample middle class housing plans to illustrate the actual utilization of this study.
