A survey was made to ascertain the indigenous folkcrafts preserved in "Hwajeon" farms in deep mountain areas with the following findings: The folkcrafts which had been handed down from generation to generation of "Hwajeon" farms were very scarce presumably because of the dwellers' frequent moves from place to place owing to their insecure liveli-hood. Moreover, the surges of modern civilization and especially the recent New-community Movement could not have by-passed the "Hwajeon" areas; nowadays, the modernization surge has all but extinguished the folkcrafts that had come down from their forefathers. The recent government policy of farm community electricalization has further helped to transform these "Hwajeon" hamlets into the modernized communities. However, in the isolated hamlets rooted deep in the trackless mountains, we can still, though very rarely, find the folklore and folkcrafts closely associated with the inhabitants' livelihood, through which we can deepen our understanding about their versatile adaptability to the desolate environment.

The reclaimed waste layer in a completed refuse small landfill site was stabilized by JSP(Jumbo Special Pattern System) method. There were some variations of landfill gases(LFGs) after the stabilization. This study investigated the landfill gases emitted from a open dumping landfill site. We measured concentration of landfill gases before and after the construction, and 28 months later. As a result, the concentrations of $H_2S$ and $NH_3$ gases before the construction were 123.51ppm and 171.54ppm, respectively. These values were higher than TWA(Time Weighted Average) values. But the concentrations of $H_2S$ and $NH_3$ gases after the construction were 55.59ppm and 20.51ppm, and they also decreased 9.04ppm and 11.82ppm in 28 months. $CH_4$ and other landfill gases after the construction were little or a little detected in the landfill site. Hence we found out that concentrations or classes of landfill gases causing some problems extremely decreased by way of the stabilization.

This study analyzed the use of scriptwriting and hologram technology for storytelling in the production of locally-centered cultural and artistic content. The musical <WolhwaJeon>, produced in the Gangneung area, was examined as a case study. The process of creating the script for the performance was used to establish the self-identity of the character "carp" and the stage visualization of the folktale "Yeonhwa." Furthermore, the use of hologram technology to actualize the inner expressions of the characters, deliver information, enhance spatiality, and visualize fantasy elements was examined. Through this approach, educational information about local folktales was provided to the local residents, and their pride in their region was heightened. This locally-centered content requires continuous development in a modern society that pursues cultural diversity, and future research is needed to produce and develop traditional and cultural content in other regions.

Total amount of Calories and protein intakes of fishing villagers show higher level than those of farming and mountain villagers, however, the proportion of animal protein (meat protein) in total amount of protein intakes of mountain villagers is much lesser than those of other two villagers. Blood specific gravity, serum protein content and serum tryptophan content were low in inhabitants of mountainous area than those of other two villagers, and in the serum protein fractions, the Albumin Globulin ratio (A/G ratio) show also lower value in inhabitants of mountainous area than those of other two villagers. It is interesting result that serum tryptophan content (serum protein tryptophan) presented a significant positive correlation with that of serum gamma globulin and a significant negative correlation with that of serum albumin. The fact of farming villagers under twenty year old female showing plasma vitamine deficiency phenomenon, however, the plasma carotene value show higher level indicates that the most of the plasma carotene being hardly transfered to the plasma vitamine A in blood. The thiamine value in urine of mountain villagers show higher level than others, it indicates that there is correlation between their poor protein intakes and amount of thiamine ia urine. And the data obtained in the present study could be established by the result of animal experiment reported by Koyanagi et al. and the result of previous paper of auther.

This study investigated the effect of nanocellulose, such as microfibrillated cellulose (MFC) and cellulose nanocrystal (CNC), and aminated starch on tensile property and thermal stability of plasticized starch film. Glycerol (23 wt%) was used as a plasticizer and nanocelluloses of 1-30 parts per hundred parts of resin (phr) in the basis of plasticized starch were added. Tensile strength and elastic modulus increased with increasing nanocellulose addition amount, whereas elongation at break decreased. Tensile properties of MFC-reinforced starch film were higher than those of CNC-reinforced film. Optimum addition amount of aminated starch, which is commonly used for paper sizing, to improve tensile property of film, was found to be 5%. And 1% addition of aminated starch showed the best effect in the improvement of tensile property of the film. Thermal stability was improved with the addition of MFC to plasticized starch film with and without aminated starch.

The rate constants for solvated electrons with benzene in the binary mixture (tetrahydrofuran-water) were measured at a various temperatures$(-18{\circ}C{\sim}+51{\circ}C)$ by photolysis. From Arrhenius plots of rate constants it was observed that the activation energies were decreased with increasing tetrahydrofuran(THF) content. Decreasing the viscosity of solvent mixtures by adding water, the rate constants were also decreased. It indicates that the reaction of solvated electrons are not controlled by diffusion. The change of activation enthalpy in kcal $M^{-1}$ and the rate constants in$ M^{-1}sec^{-1}$ were 4.90 and $8.80{\times}10^8$ for 30M% of THF, 2.80 and $5.14{\times}10^8$ for 49M% of THF, and -0.30 and %1.43{\times}10^8$ for 75M% of THF, respectively. The slope of the linear plot of activation enthalpies against activation entropies was $244{\circ}K$, which supports the reaction parameter is the change of activation entropy in the range of the experimental temperature. From the solvent effect on the activation energy, it was found that the step of the reaction, ${e_s}^-+B{\rightleftharpoons}B^-$ shifted to the exothermic reaction with increasing THF content.

The purposes of this treatise are to compare theories of theatre in 'Kwandaega' with theories of theatre in 'Poongjahwajun', to recognize differences of theories between the former and the latter, and to find out the comparative characteristics of theories of Korean theatre. There are four differences between the former and the latter. These are as follows; Firstly, in the aspect of contents, the former is consisted of discussions about nature of theatre, discussions about acting, discussions about staging, and the latter is consisted of discussions about nature of theatre, discussions about acting, discussions about staging, discussions about origin, and discussions about dramaturgy. Secondly, in the aspect of nature, the nature of theatre in the former is recognition and practice as 'homo performans', the nature of theatre in the latter is realization of 'flower[花]'. Thirdly, in the aspect of acting, discussions about acting of the former are consisted of 'Sachae' theory'(Inmulchirae, Sasulchirae, Dekm, Nerumsae), discussions about acting of the latter are consisted of method of training per ages, method of training per role playings, trainings in everyday life. Fourthly, in the aspect of staging, the focus of staging in the former is realization of an endless series of changes[千變萬化], the focus of staging in the latter is realization of 'flower[花]'. There are four characteritics in the theories of Kwangdaega. These are as follows; Firstly, the contents of kwangdaega are consisted of discussions about nature of theatre, discussions about acting, discussions about staging. This theory is theory centered on actor/actress. Secondly, the nature of thestre in Kwangdaega is recognition and practice as 'homo performans', supporting of self-generational values, supporting of folk, new interpretation about secularism. Thirdly, the discussions about acting are consist of 'Sachae Theory'. Fourthly, the discussions about staging are consisted of realizations of an endless series of changes[千變萬化]

베타선 흡수선량의 정밀측정에 사용되는 평판형전리함의 일종인 외삽형전리함(Extrapolation Chamber)으로 베타선 이온화전류의 정확한 측정을 위하여는 이온수집 단면적의 정화한 평가가 필요하다. 이를 위하여 표준 폴리축전기와 표준전압원을 이용한 충전용량 측정법으로 실제 유효 단면적을 구하였으며 측정결과는 기계적 측정치와 약 10.5%의 차이가 있음이 밝혀졌다.
