This study was carried out to study the characteristics of 6 different Sikhaes and the activity of malt. The Sikhae, a kind of the traditional Korean beverages, is made from rice and malt. The result were summarized as follows. 1. Though it takes longer when malt is manufactured at the 15℃ than at the 25℃, more excellent malt can be obtained at the 15℃ because the activity of amylase is much higher. 2. The length of the whole malt is between 3 and 4㎝ when the activity of amylase is highest. When sprout grows longer than this, the activity of anzyme falls low remarkably and the worth of malt is decreased. 3. Among the material grain to make Sikhae, the saccharifying of glutinous rice was best and the saccharifying of barleys was not so good. 4. The Sikhaes from rice and glutinous rice are not easily swollen, but the Sikhae from the barly is easily swollen and turbid. 5. The result by the sensory evaluation to determine the ranking is in the following order; Glutinous rice, Tongil glutinous rice, Nonglutinous rice, Tongil rice, Hulled barley, Naked barley.

The structural, optical, and electrical properties of ZnO thin films grown on glass by radio-frequency (rf) magnetron sputtering were investigated. The mixture flow ratio of $O_2$ to Ar, which was operated with sputtering gas, was chosen as a parameter for growing high-qualify ZnO thin films. The structural properties and surface morphologies of the thin films were characterized by the X-ray diffraction and the atomic force microscope, respectively. As for the optical properties of the films, the optical absorbance was measured in the wavelength range of 300-1100 nm by using UV-VIS spectrophotometer. The optical transmittance, absorption coefficient, and optical bandgap energy of ZnO thin films were calculated from the measured data. The crystallinity of the films was improved and the bandgap energy was increased from 3.08 eV to 3.23 eV as the oxygen flow ratio was increased from 0 % to 50 %. Furthermore, The ultraviolet and violet luminescences were observed by using photoluminescence spectroscopy. The hall mobility was decreased with the increase of oxygen flow ratio.

This study was considered and analyzed "Jun-Kwa" Korean traditional sweets. I chearly mentioned about all the remains of Junkwas, their frequency, the ingredients the changes of cooking method. Junkwa were 51 Kinds in number. The material of Junkwa consists of roots or branches of plants and fruits which can be obtained easily. Boiled or raw materials mixed with honey or sugar are boiled down. The dried Junkwa means that processed Junkwa with dry sugar was dried by sun shine for reservation. A dish with many kinds of Junkwa was called KaKsak Junkwa. Sangsil Kwa was used to decorate Suksilkwa.
자발 형성된 인듐비소 양자점의 광여기 발광에 미치는 열처리 효과
조신호 가톨릭대학교 자연과학연구소 2001 自然科學論文集 Vol.9 No.-
We present the effects of thermal annealing on the photoluminescence (PL) properties of self-assembled InAs quantum dot structures grown on GaAs substrates by molecular beam epitaxy (MBE). The PL measurements as a function of temperature are performed in a closed-cycle refrigerator in a temperature range of 17 to 280 K. Annealing at higher temperature results in an increase in island size, a corresponding decrease in the density of islands, and a redshift in the PL emission from the islands. The different values of thermal quenching activation energies for the unannealed and annealed samples indicate a variation of the quantum dot confining potential.
급속 열처리 온도에 따른 자발 형성된 InAs 양자점의 구조 및 광학 특성

We present the effects of rapid thermal annealing (RTA) temperature on the structural and optical properties of self-assembled InAs quantum dot (QD) structures grown on GaAs substrates by molecular beam epitaxy (MBE). The photoluminescence (PL) measurements are performed in a closed-cycle refrigerator as a function of temperature for the unannealed and annealed samples. RTA at higher temperature results in the increase in island size, the corresponding decrease in the density of islands, and the redshift in the PL emission from the islands. The temperature dependence of the PL peak energy for the InAs QDs is well expressed by the Varshni equation. The thermal quenching activation energies for the samples unannealed and annealed at $600^{\circ}C$ are found to be $25{\pm}5meV$ and $47{\pm}5$ meV, respectively.
