곡물 bin을 이용한 벼의 건조실험을 수행하여 상온통풍건조 시스템과 태양열 건조 시스템의 건조 특성을 비교하여 분석하였다. 태양열 건조의 시뮬레이션 모형에 대한 컴퓨터 프로그램을 개발하였으며 시뮬레이션 모형에 의한 함수율의 예측치는 실측치와 전체적으로 일치하였다.<br/> 또한, inverter를 사용하여 벼의 건조 상태에 따라 송풍량을 적절하게 제어하는 송풍량 제어 시스템을 개발하였으며, 개발된 송풍량 제어 시스템을 통하여 에너지 절약 효과를 얻을 수 있었다. In-bin grain drying experiments were performed to investigate the drying characteristics between natural air and solar heated-air drying system of rough rice. A computer simulation model for solar drying system of rough rice resulted in a good agreement between the experimental and predicted moisture content.<br/> In order to save the electric energy consumption of fan, airflow rates control system using inverter was developed and resulted in the effect of energy saving.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherpy seems a logical choice for cancer chemotherapy. The Mitomycin C(MMC) adsorbed by the activated charcoal particles(CH) is relatively released when the drug concentration surrounding the carbon particles becomes low in the peritoneum of the peritoneal cavity. For the intraperitoneal chemotherapy on the advanced gastric adenocarcnoma, mitomycin C adsorbed on activated carbon particles was administered in the peritoneal cavity just before abdominal wall closure. The closed drainage tubes were inserted in the peritoneal cavity and clamped for tuo hours after completion of operation. MMC concentrations were serially measured in peritoneal fluid, plasma and urine at 2hour, 48 hour, 72 hour and 168 hour following its administration in order to study the efficacy of the MMC-CH as a drug delivery system. There were minimal toxicities in born marrow, liver, and gastrointestinal system after intraperitoneal MMC-CH administration. The data of this study suggested that MMC-CH may have a somewhat more beneficial effect than surgery alone when administered in optimal dose and schedules, but the MMC concentration of the peritoneal fluid was not sufficient to eradicate remnant cancer cells, and effective duration of maintenance was only below 24 hours in the peritoneal fluid and plasma.

In addition to the development of functional cosmetics, technology to increase percutaneous absorption rate when applied to the skin is an important task. In this experiment, oleic acid was used as a skin absorption promoter, and its effect on transdermal permeability of adenosine was studied and analyzed using a skin-like membrane. As a result of the experiment, it was investigated that the permeability coefficient and concentration of adenosine are proportional to the content of oleic acid. This indicates that a high proportion of oleic acid is effective as a skin absorption promoter.

In this dissertation, we have studied on the fabrication of Sr ferrite plastic magnet with additional Nd. First, we selected SrO5.9F₂O₃of nonstoichimatric composition as the basic composition of specimen ferrite since its magnetic property was excellent. Then, we added Nd to the specimen. In order to control the properties of the particles on fabrication of magnetic powder, 0.3wt% CaCO₃, 0.2wt% SiO₂, 0.twt% Al₂O₃and 0.5wt% Na₂SiO₃were added. For carbon coating ont he compound specimen, 5wt% polyvinylalchohol was added and then the compound specimen was calcinated under N₂environment at 1,225 ℃. After performaing grinding process for 18 hours, we obtained 1.0~1.2㎛ size of single domain magnetic powder. We added 1 wt% silane coupling and 1 wt% calcium stearate to the Sr ferrite powder with additional Nd, and then mixed them well. Next, we pelleted them after kneading them, using polyamide12 as a binder. The pelleted specimen was injection-moulded using anisotropic mould under magnetic field of 12kOe. As the results of property tests for the fabricated specimen magnet, we find that the fabricated magnet has the following excellent peroperties at Nd 12.5wt%: bHc=2.84kOe, Br=3.23kG and (BH)max=2.49MGOe.

Two quadruplex PCR reactions were designed for 7 tetrameric (D3S2406, D4S2368, D5S818, D7S821, D9S925, D13S317, D19S253) and one trimeric (D6S1043) short tandem repeats loci to study the allele frequency and the applicability of genetic variation in these loci in forensic case works. For 310 unrelated Koreans DNA was isolated from peripheral blood using phenol/chloroform method. Quadruplex I was consisted of D4S2368, D6S1043, D7S821, D9S925 and quadruplex II D3S2406, D5S818, D13S317, D19S253. The amplified products were analyzed by 5% polyacrylamide gel electrophoresis followed by silver staining. The heterozygosity in each loci ranged 92.91-66.13%, and PD(Power of Discrimination) was above 085 in each loci. Every loci except D6S1043 followed hardy-Weinberg expectation. The cumulative PI was low as 1.65×10-10. Two mutations were noted, one in D19S253 and the other in D9S925 among 234 gametes. With these results above eight STR loci studied here preyed to be highly polymorphic enough to be used in forensic field. This study provides valuable population data in these loci for Korean.

Thin amorphous carbon films were deposited by a Q-switched Nd;YAG 532nm with beam power density of ?? on the high purity graphite (99.7%). The pressure of vacuum chamber was ?? Torr. In order to estimate the quality of the Pulsed Laser Deposition films one of the most important optical properties, bandgap energy, was characterized by transmission and reflection in the range of the visible, and an optical direct bandgap energy of 2.45eV and indirect bandgap energy 0.36eV were obtained. Surface morphology of amorphous film was investigated by AFM (Atomic Force Microscopy). Its surface roughness is 70nm. Comparing our results with the published values in the literature we have confidence that our films show the good quality for optical properties.

The variables of psychological maturity according to triathlon participation experience The purpose of this essay was to make an inductive analysis through an open type questionnaire in order to compare the psychological. Thus to achieve the above goal, following research problems were set. First, is there any difference in the variables of psychological maturity according to triathl on participation experience? The quantitative research to solve the above problems was conducted to total 600 participants and non-participants, and the qualitative one was to 50 persons concerned. The collected data was statistically processed using frequency analysis, t-verification. The findings presented through the data analysis are as follows. First, there was difference in the variables of psychological maturity according to triathlon participation experience. The participants were shown to be higher in all variables of psychological maturity then the non-participants, and most participants were relatively higher in the factor analysis of participation experience by age and gender than the non-participants, but the age class under 20 showed no statistically significant difference in the sub-factor of psychological maturity, emotional stability, and that in their 40s showed no statistically significant difference in the positive thinking and psychological self-effectuation.
