MoO_3 : Co 박막의 광학적 Energy Gap Co Thin Film
이현순 圓光大學校 基礎自然科學硏究所 1987 基礎科學硏究誌 Vol.6 No.2
Molybdenum oxide thin films were prepared by spray pyrolysis method. Methyl alchol solution of molybdenum acetylacetonate doped with 0.01M cobalt acetylacetonate was sprayed on glass substrates at 83℃. The films were annealed in air at 300℃, 350℃, 400℃, 450℃ and 500℃ for one hour. The optical energy gaps for these films at 295K were given as 2.56ev for MoO_3:C_o and 3.18ev for Mo_9O_26:Co.

We analysed the demographic data, clinical course and forms of renal replacement therapy of 149 children with chronic renal failure observed between 1985 and 1995. The most frequent cause of CRF is chronic primary glomerulonephritis(35%of the total) followed by chronic pyelonephritis(23%), Induding obstructive uropathy and reflux nephropathy. Reflux nephropathy (1996) was the most common cause of CRF as a single disease entity. In children under five years of age chronic pyelonephritis(42%) predorninates chronic primary glomerulonephritis(12%). Most patients with end-stage renal disease received renal transplant from living related donor after some period of maintenance of dialysis. The cardiovascular disorders were the main cause of death(4 patients). Survival of patients with CRF improved markedly from 22% in 1980-1985 to 88% in 1985-1990; this might be due in part to the improvement of dialysis and transplantation techniques and that of socioeconomic status.

SnS_2 : Co 單結晶의 光學的 特性에 관한 硏究 Co Single Crystals
李絃順 圓光大學校 基礎自然科學硏究所 1991 基礎科學硏究誌 Vol.10 No.1
The SnS_2 : Co single crystals was grown by the Chemical Vapour Transport Method using iodine as a transporting agent The structure of SnS_2 : Co single crystal was hexagonal and the measured lattice constant a= 3.638 A, C= 11.832 A. The Optical energy gap was measured to be 2.060 eV for SnS_2 : Co single crystal and 2.265 eV for SnS_2 single crystal at room temperature. The photoconductivity peak appeared at 575nm in the photoconductivity spectrum of SnS_2 : Co single crystals. I observed two PL peak at 549㎚, 881㎚ in the photoluminescence spectra of SnS_2 : Co single crystals

Molybdenum oxide thin films were prepared by spray technique. Methyl alchol solution of molybdenum acetylacetonate was sprayed onto glass substrates at 83℃. Heat treatment of films in air at 250℃, 300℃, 350℃, 400℃ and 450℃ for one hour transformed them into amorphous (at 250℃), crystalline M_0O_0(at 300℃, 350℃) and crystalline M_09O_26(at 400℃) respectively. Films have the optical band gap of 2.7eV(at 300℃), 2.64eV(at 300℃), 2.3eV(at 400℃) respectively. The grain size of these films were 685nm(at 350℃) 853nm(at 450℃).

1. The numbers of general bacteria, total coliforms bacteria, feal coliforms and fecal streptococci was greater in June and October than in Aprial and March. 2. There was a difference in bacterial population according to location. Data demonstrated that in the Chon-Chon reservoir and the Ui-Am reservoir fecal streptococci were present in greater numbers than fecal coliforms bacteria were, but that fecal Coliforms bacteria were present in greater numbers in Pal-Dang, Won-Ju(Moom-Mak) and Yo-ju.

풀라터너스의 기공의 分布는 평균㎟ 150개정도로 高等植物의 ㎟당 100∼300개에비해 중간정도이고 氣孔의 크기도 비교적 적다고 보고 청계천의 것과 校內의 것을 비교했을 때 청계천의것이 기공의 크기가 약간적으나 碌黃含量은 많은 것으로 보아 기공의 크기와 SO_2까스吸收와 직접적인 관계는 없다고본다 청계천의 것에 있어서 chlorophyll 감소가 校內보다 빠르고 Phaeophytin이 많이 생긴 것은 역시 公害와 관계된다고 생각된다. A comparison has been made of the effects of pollution on platanus by observing two separate areas where it grews. One area is along Chongge-chon and that is highly polluted with SO_2 from automobiles. The other is on the campus of Sung-Kyun-Kwan university which is less polluted. The comparison includes size and number of stomates and the chlorophyll content. Generally Platanus leaves contain 150 stomates per ㎟ and the stomate size is small. The trees along Chongge-chon exhibit ever smaller sized stomates and a higher sulfur content than can be formed in SKKU area. So it can not be said that small stomate size is parallel to less absorption of SO_2. However we can consider that because of the smaller stomate size plants with small stomates have more resistance to SO_2 gas than other plants with larger stomates. The chlorphyll a,b ratio is 1.5, because of the small content of chlorophyll a. It is also to be noticed that the phaeophytin in the platanus along Chongge-chon has more than 10 times the amount than in the platanus at SKKU, and that it disappered according to decrease of chlorophyll a.

Chemical Composition and Anti-Stress Effects of Yeast Hydrolysate
이현순,정은영,서형주 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.6
In the present study, the anti-stress effects of yeast hydrolysate (YH) were investigated. The YH consisted of crude carbohydrate (23.6%) and crude protein (68.3%) with low contents of crude ash (3.1%) and crude fat (0.3%). Also, acidic amino acids (glutamic acid+aspartic acid) were present in large quantities (14.2 and 5.0mol%, respectively). Pronase digestion had little effect on the affinity of the YH on 5-hydroxytryptamine (serotonin) and norepinephrine transporters, whereas NaIO4 oxidation of the hydrolysate decreased the affinity by about 10% at 1,000μg/mL, indicating that the periodate-labile carbohydrate moiety played a leading role in the affinity effects of the carbohydrate in YH. As a result of brain mapping after the administration of the YH for 3 days in human subjects, a symmetrical distribution of theta and alpha waves in the central and parietal lobes was observed. This brain mapping pattern of theta and alpha wave distribution appears in a psychologically stable state. The YH groups showed improvements in Beck Depression Inventory and Beck Anxiety Inventory scores after YH administration for 2 weeks. Treatment also seemed to have a more significant (P<.05) impact on the somatic manifestations of anxiety as indexed by the Beck Anxiety Inventory scores. Food materials used as a source of YH have been found to be associated with increases in alertness and adaptation to stress.
