위암환자의 위액단백과 Amylase의 분리와 성상에 관한 연구

정부근,고재경,노연희 한양대학교 의과대학 1992 한양의대 학술지 Vol.12 No.1

Amylase activity was measure din gastric juice and cancer tissue of patients with stomach cancer to find out the possible use of the enzyme as a biochemical marker for stomach cancer. Amylase and proteins in gastric juice from patients with stomach cancer were separated by a DEAE-cellulose column chromatography to investigate the enzyme and proteins specific to the stomach cancer. (1)Protein content and amylase activity were not changed in gastric juice of patients with gastritis and duodenal ulcer, but significantly increased in gastric juice of patients with stomach cancer. The positive rate of protein content and the enzyme activity in the gastric juice as a marker for stomach cancer was relatively high. (2)Protein content in the stomach cancer tissue was significantly increased and amylase activity was greatly increased in 3 cases out of 12 cases of the stomach cancer tissues studied. (3)Substrate specificity and effect of halogen ions on amylase in gastric juice of patient with the stomach cancer was similar to those on the enzyme in the stomach cancer tissue. (4)DEAE-cellulose columkn chromatography revealed that proteins in gastric juice were separated into 8 peaks in the stomach cancer and into 6 peaks in the control. Amylase in the gastric juice was separated by the chromatography into 2 isozymes in the stomach cancer, but not in the control. Substrate specificity for the two gastric juice amylase isozymes was observed to be different. These results indicate that protein content and amylase activity in the gastric juice could be used as a biochemical marker for the stomach cancer and that amylases specific to the stomach cancer appear to be released from the stomach cancer tissue.

The object of this stucy is to rational and estimate for strean water quality of Sa-Song industrial Complex it is hazard to piecemal assess the stream water quality, brcause the water quality is Very diverse with time and each procese and so we need to qverall estimate for the assese. The results of interpretation by the statistical technigece, using the analyzed dates from each sampling point of Eum-Gung and Hah-Jang Chaon, are as fallows : 1. The Variances of Original date cam be describe implicity by the first two pricncipal components. 2. Each principal compoment daes not alwags represent the Same factor to other strean and characteristics. 3. The pattern of waste water discharge can be predicted by periodie function of time - Variable.

演繹과 歸納에 關한 考察

李忠杰,金富允,金東華 釜山大學校 師範大學 1988 교사교육연구 Vol.17 No.-

In this paper, we point out that the knowledge of deduction method being suitable for persuading someone to approve a statement is unsuitable for necessity of deductive reasoning. For such knowledge, the recognition of difference between inductive reasoning and deductive reasoning is required. Such a knowledge is acquired some empirical components and some social components. David Bloor says, theoretical components of knowledge is one aspect of such social components. The atmosphere of classroom, attitude of teacher, attitude of other students are variables of such social components. Students in classroom study the knowledge of inductive method and deductive method with some social components, after this, students recognize the difference between inductive method and deductive method, after all, students recognize the necessity of deductive method for proving a statement.

Polyvinylidene fluoride의 ^(60)Co 감마선 조사에 의한 구조 변화

이청,김기엽,류부형 한국안전학회 2004 한국안전학회지 Vol.19 No.3

The radiation-induced changes taking place in poly(vinylidene fluoride) (PVDF) exposed to ^(60)Co γ-ray irradiation were investigated in correlation with the applied doses. Samples were irradiated in air at room temperature by ^(60)Co γ-ray to doses in the range of 200 to 1000kGy. Various properties of the irradiated PVDF were studied using MF, differential scanning calorimetry (DSC), gel fraction and elongation. ^(60)Co γ-ray irradiation was found to induce changes in chemical, thermal, mechanical and structural properties of PVDF and such changes vary depending on the radiation dose.

이중면 불연속 구형 도파관의 특성 해석

Double-plane steps discontinuity in rectangular waveguide is investigated with TE^(x)_(mn) mode analysis. This method accounts for the influence of evanescent fields and power transmission due to higher order modes. For these discontinuites the electromagnetic fields are derived and the scattering matrix is derived by applying the continuous condition in discontinuity. The scattering coefficients of a X-band to Ku-band waveguide transition as well as of resonant iris with finite thickness (t=2.0mm) are calculated and compared with Patzelt's result. The scattering coefficients of the resonant iris (a= 7.112mm, b= 3.556mm, a_(1) = 4.0mm, b_(1) =1.0mm, t=0.5mm) are calculated and compared with Bornemann's results.

포유동물에 있어서의 시간생물학(chronobiology)

곤충류는 지구상의 육상동물중 개체의 생존에의 필수의 방어능력, 유지에 해당되는 가장 잘 조화된 행동반응(behavioral periodicity)으로 오늘날에 이르고 있는 것으로 알려져 있어 이들의 기본적인 반응(Circadian 리듬등)에 대하여 소개하였다. 이와같은 현상은 사람이나 마우스의 혈액세포 또는 비장세포에서도 circadian 리듬이 있음이 밝혀졌다. 이와같은 기초연구를 바탕으로 하여 똑같은 조건하에서 수술시간대만을 달리 설정하여 쥐에서 신장이식 수술을 실시한 결과 수술시간대별에 따라서 생존율에 크게 차이가 있음(circadian 리듬)이 알려졌다. Many of activities of insects(locomotion, feeding, mating, oviposition, eclosion, etc.) also occur at regular intervals. The patterns of recurrence of particular activities may be every 24 hours, monthly, annually, in coordination with thee lunar cycle(rhythm), and so on Periodicity in behavior involves both endogenous and exogenous components. Endogenous components are related to its heredity. These include, in particular, rhythms, but the stage in a given physiological-behavioral cycle, developmental stage, and other endogenous factors may also play a role. Exogenous components arise from the external environment Rhythms are processes that are controlled by an biological clock gene. They characteristically continue even when external conditions(temperature, light, etc.) are kept constant. Most rhythms that have been identified have a period of approximately 24 hours and are referred to as circadian(about a day) rhythms. Several examples of circadian rhythms have been identified in mammals. A variation of the immune response are studied by performing kidney allografts across a strong genetic barrier at different time points of the day in rats standardized in light from 06^(00) to 18^(00), alternation with darkness. Transplantations were done at each of the following midpoints : 00^(00), 04^(00), 08^(00), 12^(00), 16^(00), and 20^(00). A mode in mortality is found in this histocompatible combination at approximately seven days after kidney transplantation. At 21 days the survival rate is 50 percent for the allografts performed at 20^(00). Rhythme characterizing the surgeon, as well as the donor and the recipient, probably are involved in transplantation. The interaction of such rhythms is revealed by the bioperiocity of postoperative survival times.

Received field strength in land mobile-radio communication must consider characteristics besides. This paper analysis propagation chracterics to multipath and then compute theoretical value of field strength which vectorial compose and compared with measured value. Seorm base station is to unity south area of Cheju by single propagation area. But Gunwelak base station cause a weak and impossible received field area to increase obstruction. In order to replace it, we necessary technique study of new mobile communication propagation environment. For take a accuracy received field strength, the first thing field strength of a point must measure many times and calculate mean value of it. The second we must suggest and analytical modeling to compose to these measured values.
