The purpose of this study is to clarify that 'Kanghosasiga' is the Ynsijo which has general unification of the content and having general unification is based. on the using one definite frame. although 'Kanghosasiga' used different subject matters that have characteristics of four season in forming one theme. The definite frame is divided into two frames, inner frame and outer frame. Outer frame is common in four works, and it represents the place in which the speaker lives(강호), speaker (이몸), relationship between speaker and the king(군은), the condition of 'kangho' and speaker. And in this paper, the generative condition of phrases is so analyzed that the compression and the simplicity of expression are explained, and the purpose of generative phrases is so analyzed that satisfaction at life is represented. It is considered if it is possible to extended to '태평성대(the happy era)' in the social view. Inner frame is the detail structure of content of the work. Each of the first, second, third of the verses of four works have common structure. After analyzing each content, the characteristic of 'Kanghosasiga' was explained. The first of verses of 'Kanghosasiga' represent gusto of the four season. The second is constructed with 'the clause that functions as instruction' because 'speaker' that is the words that functions as index, and represents in detail gusto of the first. The third is connotative expression connected with the second. The third implies purpose that the writer try to gain private living with formal viewpoint. The structure of the inner frame of 'Kanghosasiga' shows a process; 'introducing season' $\to$ 'gusto about season' $\to$ 'enjoying with season' $\to$ 'peace in mind'. The first of verses of 'Kanghosasiga' is the clue of the second. The second is the reaction of the first. The third has character as estimation of the forepart. The structure of the outer frame can be shown if the structure of the inner frame has '감군은‘(being grateful to king's grace). ultimate purpose of the writer is to praise king's administration.

The Younsijo is a stream of Korean poem. not simply an aggregate of stanzas, but an organic structure. Younsijo was an appeared in the 16th century. The 16th century was focused on the literature of Sadaebu (noble family, 사대부). And the make an appearance is Danhyungsijo (simply-sijo, 단형시조), Yonsijo and Kasa(가사). In that case, a social stratum is why does singing each other form. The 16th century set metaphysics(성리학) as the national ideology. Metaphysics became most prevalent at the end of the 16th century. Yonsijo also appreared during the 16th century and was closeiy related to the idea of metaphysics. Both Younsijo and metaphysics were formulated by noble family, The Yonsijo was Formed in 16th century. And the 17th century was succession. The Yonsijo in 16th century is devide to Kanghosijo (강호시조) and Hunminsijo (훈민시조). Also, Kanghosijo is devide to Youkgaline Younsijo (육가계 연시조) and Sasigaline Yonsijo (사시가계 연시조). Hunminsijo used an expressive on the order of Oryoun(오륜). Therefore, this study is forced on , , and . These things, all of the end of the utility. This paper deals with Danhyungsijo and Kasa with main emphasis on works of Songgang(송강) Jungcheol(정철). The reason for dealing one writer's works is the discussion needs consistent standard. In analyzing Songgang's Danhyungsijo, Younsijoand and Kasa, one would discern the differences among three. As a result, one could conclude that both Danhyungsijo and Kasa mainly projects individual's emotional esthetic feeling, particularly, Danhyungsijo for emotional implication, and for in-depth emotional revealing. Younsijo were chosen as it supplements the shortcoming of Sijo(as it consists of three-line only) to effectively contain the ideas of metaphysics.

This study was carried out to define the effect of electron beam irradiation on the physico-chemical characteristics of sewage sludges. The experimental evidence showed that both pH and alkalinity of irradiated sludge were generally increased as the dose of irradiation increased. It was found that the soluble protein concentration (SPC) and soluble chemical oxygen demand (SCOD) from the sludge right after electron beam irradiation at 3kGy(kilo-joule/kg) increased 2.2 times and 10 times respectively more than those sludges without electron beam treatment. This highly solubilized organics could be resulted in a good soluble substrate for the subsequent anaerobic digestion process. The specific resistance of filtration (SRF) tests showed that sludge dewaterability under electron beam irradiation at 6kGy was found to be 8.8 times higher than that of unirradiated sludge. The sludge dewaterability seemed to be directly related to the dosage of electron beam irradiation up to 10kGy. However, the efficiency of sludge dewaterability tended to be smaller with higher applied irradiation dose. In comparing treatments by different inorganic chemical conditioner with irradiated and unirradiated sludges, it appeared that the dewaterability with irradiated sludge was approximately 4-10 times better that that of unirradiated sludge. Even electron beam treatment itself could replace the result from the sludge conditioned with inorganic chemical coagulants.
