竹材의 合板製造에 關한 硏究 : 第2報 竹單板 乾燥 및 接着力에 對하여 Ⅱ. On the Adhesion and Drying of Bamboo Veneer
李敬允,洪秉和 慶尙大學校 1976 論文集 Vol.15 No.-
竹材 合板 開發을 目的으로 竹單板 乾燥 및 接着力을 究明하기 爲하여 試驗하여 얻은 結果를 要約하면 다음과 같다. 1. 竹單板 乾燥조건 (1) 溫度에 따른 乾燥時間은 乾燥溫度 100-140˚C下에서 含水率 90%일 때는 3分, 含水率 30%일때는 1分이 소요되었다. (2) 單板 두께別, 含水率別, 適正乾燥條件은 單板두께 0.3, 0.6mm의 경우 含水率 70, 50, 30%時의 乾燥溫度는 100℃에서 風速은 1m/sec가, 1mm 單板은 乾燥溫度 70%時는 100℃에서, 30%時는 100-140℃에서 1m/sec의 風速이 適當하였다. 2. 單板接着條件 (1) 接着濟 種類別 接着力은 索소指接着劑와 메라민 索소指接着劑別 대나무 單板 接着力은 常態接着力이 40kg/㎠, 接着力은 17kg/㎠ 그리고 溫冷水浸적 接着力은 26kg/㎠로서 基準店着强度보다 2~5倍의 優秀한 接着力을 보였다. (2)接着劑 ?布量別이 있어서는 常態試驗에서 25gr/sg·ft, 溫冷水試驗에서는 35gr/sg·ft로서 가장 높은 값이나 適正芬布量은 30gr/sg·ft임을 알 수 있었다. (3) ???力別 接着力은 常態試驗에서 15kg/㎠,耐水試驗에서 10kg/㎠일때가 가장 높에서 대나무 單板의 경우 열??力은 10kg/㎠以上이 要求되었다. This experiment was carried out to find the suitable dry condition and abhesive strength of bamboo veneer for the impnovement of plybamboo technique. The results are summarized as follows: Ⅰ. Suitable dry condition shown by moisture content and veneer thickness. 1. When the veneer of 70, 50, and 30% of moisture contents were used, the optimum drying periods were estimeted as three, two and one minute respectively. 2. Adequate temperatures and air velocity for each thickness and moisture content of bamboo veneer were determined as follows: Ⅱ. Adhesive subatancer and adhesive strength. 1. When urea resin glue and melamine ruea resin glue were used as adhesive substances, the adhesive strength were estimated as 40kg/cm²under the boiling test. And above estimates were seemed to be 2-3 times highter than that of standard adhesives. 2. The maximum adhesive strength were exhibited when 25gr/sq.ft of adhesive were used under the normal test, and 35gr/sq.ft under the hot and cold soaking test. Consequently, the adequate amount of adhesivs substancer was estimated as 30gr/sq.ft. 3. The maximum adhesion strength shown by hot pressure of gluting was estimated as 15kg/cm²under the normal test, and 10kg/cm² under the water proof test. These adhesive strength would be enough for the practical use in plybamboo technique, for the appropriate strength for this technique is supposed to be 10kg/cm²

This paper is a study on the system of the local legislature which has not attrached much attention so far. The objectives of my study on the local legislaturem are as follows; first to locate problems of local legislature of Korea in 1950s and to find desirable direction for institutionalization of local legislative system. Second, to find the characteristics of the local legislative system by analyzing the interaction between leading variables and environmental variables, in connection with the contents of legislation. The scope of this study is confined to the local council of Korea from 1952 to 1960. And the methodology I employed are ecological approach, judicial-institutional approach and system-functional approach which are useful for analyzing the interaction among various variables. But the lack of materials did not allowed a case study and a sophisticated analysis of the local legislative process in 1950s. The major contents of this paper are as fllows; first, the local legislative system is composed of leading actors, environment and istitution of local council. Second, the different characteristics and the process between national legislation and local legislation are analyzed. Third, the Korean local legislation are different from foreign local legislature in various ways are also analyzed. Finally, on the ground of the findings of the analysis the necessity of strengthening the role and function of the local councils is suggested to accomplish much a purpose fellowing measure are desirable. 1) Democratic procedures in the local politics are required to counteract the intervening of the central political power as an environmental variable. Because the analysis of central-local politics and local legislative system showed that the change of central political power had been more influential than local council which is self-government through elected representatives. 2) To secure a productive coordination between the central government and the local government decentralization should be institutionalized. 3) To vitalize local Democracy, the power and activities of local councils of which functions are to promote political participation of the people should be guranteed and freely exercised.

The objective of this study is to find the factors which have brought about the lack of political participation and power held by women. This study is divided into three parts according to the approach. 1. Theoretical approach : I analyzed Korean women's political participation in a conceptual framework of the sex role differences and described the feminism theories which are connected with the political participation. And then I could find that the lack of women's active political participation results from the sex role differences of the patriarchal system and the capitalism system. 2. Empirical approach : I summarized the history of the Korean Women's political participation movement and researched the political behavior of ,the elite women who participated in political reality in the past. And ,then I described most of Korean women's political consciousness. As a result I could find the fact that Korean women's political consciousness is considerably advanced. So their political ambitions are getting greater. Nevertheless, they have a passive orientation to the political participation. 3. Analytical approach : The passive political orientation is originated by three factors : Korean family system with the sex role differences, capitalism of class conflicts, and authoritarian political regime deriving from the divided situation of Korea. In order to induce women's active political participations, I suggest a few important points as follows. 1. The direction of the feminism ideology must accord with political target in Korea, because it is a essential part of the women's political participation. 2. Korean women have to systemize their political power through labor and feminism movement, because it is an embodiment of tactics in the active political participation. 3. It needs to develop the women's political education for the reformation of patriachal system, because it is a necessary condition of the active political participation.
