We characterize the fuzzy ideal generated by a fuzzy subset in a semigroup and the fuzzy interior ideal generated by a fuzzy subset in a semigroup. Our work generalizes the characterizations ([8]) of those fuzzy ideals generated by fuzzy subsets in semigroups with an identity element.

In "Maekyojeongmiron(脈要精微論)", Jangbu(臟腑) is assigned to Chon.Gwan.Cheok(寸關尺) in according to the position. Kidney[腎] is assigned to the backward area of Cheok. Abdominal cavity[腹中] is assigned to the middle area of Cheok. Hypochondrium[季脇] is assigned to the forward area of Cheok. Liver[肝] is assigned to the backward area of left Gwan. Diaphragm[鬲] is assigned to the forward area of left Gwan. Stomach[胃] is assigned to the backward area of right Gwan. Spleen[脾] is assigned to the forward area of right Gwan. Heart[心] is assigned to the backward area of left Chon. Central part of the chest[膻中] is assigned to the forward area of left Chon. Lung[肺] is assigned to the backward area of right Chon. Thoracic cavity[胸中] is assigned to the forward area of right Chon. This method of assignment is simple and useful in clinic.

Objectives: The purpose of this study is to report the effect of Korean medicine treatments on Postoperative symptoms. Methods: The patient was treated with herbal medicine, acupuncture and electronic moxibustion. The efficacy of treatment was evaluated with visual analogue scale (VAS), the degree of symptom relief and presence or absence of symptoms. Results: After hospital care with korean medicine treatments, symptoms such as fatigue, lower abdominal pain, thirst, hot flush, cold hypersensitivity of hands and feet and tinnitus were disappeared. Conclusions: To promote physical strength and reduction of fatigue, intensive hospital care with korean medicine treatment seems to be effective. After discharge, continued outpatient treatment for complications of surgery and menopausal disorder seems to contribute to quality of life and satisfaction for patient who undergoing hysterectomy.

Fault of under ground power cable occurs usually from the water tree such as the vented tree, the bow tree and the water-rich halo. The water tree penetrates to the polyethylene cable insulations. Sometimes, the water tree also diffuses to mother cable in the substation. In this paper, instead of replacement of the faulty cable, we tried to cure an electrical power cable degraded by the water trees with silicon injection method. And measured the results with the isothermal relaxation current analysis method. After cable cure, Chonil line was improved from 2.27 to 1.96 in a phase, from 2.148 to 2.020 in b phase, and from badness to 2.192 in c phase. And Keumam line was also improved from 2.419 to 1.920 in a phase, from 2.301 to 2.000 in b phase, and from badness to 1.957 in c phase.

This study aims at what is required knowledge and ability to pre-service math teachers in teacher certificate examination. First, the items are analyzed and among questions of discipline of mathematics education in the last five years are analyzed and classified. Second, an analytical framework suitable for item analysis is examined and the items are analysed by the analytical framework. Finally, helpful implications for discipline of mathematics education assessment can be drawn from this study. It is found that the discipline of mathematics education assessment has the following characteristics: 1) It assesses specific content of the assessment component; 2) It assesses a teacher's theoretical knowledge, practical knowledge and creative knowledge in terms of teaching ability; 3) There are six cognitive assessments; 4) There is an item for difficulty adjustment.

Chemical composition and condition of acid hydrolysis of waste composts during the cultivation of oyster mushroom (Pleurotus ostreatus) were determined. Ash content of composts increased while organic matter content decreased as the cultivation progressed. More than 90% of mushroom was produced from the first and second cropping period. An optimum condition for acid hydrolysis was at 2.0% $H_{2}SO_{4},\;1.5kg/cm^{2}$ vapor pressure for 30min and 20times (acid/compost). Formation of furfural in acid hydrolysis increased remarkably as acid concentration increased.
