Background and Objectives : Epidermal growth factor receptor (EGFR), a 170-kDa transmembrane glycoprotein, appears to mediate epidermal growth factor (EGF) activity. Transforming growth factor-α and EGF produce their biological effects in numerous systems by stimulating the EGFR In this study, we examine the postnatal development of EGFR immunoreactivity in the different regions of the thalamus of the rat Materials and Methods : The present study is based on 28 postnatal cases of rat thalamus ranging from the day of birth, postnatal day 0 (P0) to 30 days (P3, P5, P10, P15, P20, P30), and these cases were compared with adult rat thalamus. Cryostat sections were processed free-floating with monoclonal antibody by immunohistochemistry Results : EGFR immunoreactivity in the thalamus of the rat showed very different patterns according to postnatal ages and thalamic areas. EGFR-immunoreactive cells appeared in the first two postnatal weeks, except the ventral posterior thalamic nuclei. In the early postnatal days, EGFR-immunoreactive cells appeared thalamic midline structures, increased progressively in the first two postnatal weeks, and followed mediolateral gradient. The mature patterns of EGFR-immunoreactive cells were achieved at P20 Conclusion : These data indicate that the maturation of EGFR-immunoreactive cells requires a relatively prolonged period of time to achieve an adult configuration. Many growth factors probably play protective or neurotrophic roles at EGFR-immunoreactive neurons of thalamus both young and adult rats In addition to difference in time of appearance in thalamic nuclei and developing pattern with mediolateral gradient suggest that EGFR-immunoreactivities are correlated with the appearance of the related functional.

Equatorial-Skew형[Co(TRDTRA)(OH₂)]착물과 ??,?? 그리고 ?? 이온 간의 치환반응결과 생성된 차물의 치환반응성 및 구조를 전자흡수 스펙트럼과 Yamatera 이론에 따라 조사하였다. 속도론적 자료로부터 착물과 ??,?? 그리고 ?? 이온의 반응차수는 각각 1차이며 총괄 반응차수는 2차임을 알 수 있었다. ?? 및 ?? 이온에서 생성된 착물의 구조는 이성질화 반응이 동반된 Polar-Chair 형이며, ?? 이온의 경우에는 이성질화 반응이 동반되지 않은 Equatorial-Skew 형임을 알 수 있었다. The substitution reaction and structrue of products obtained from the reaction of Equatorial-Skew-[Co(TRDTRA)(OH??)](TRDTRA=trimethylenediaminetriacetate) with ??,??, and NCS ions have been investigated by means of electronic absorption spectroscopy and theoretical calculation based on the Yamatera`s theory. According to kinetic data, the substitution reaction order for the complexes such as ??,?? and ?? was the first order, respectively, and overall reaction order was second order. It has been determined that the structure of products having ?? and ?? ions was Polar-Chair type complexes which were accompanying with isomerization and having ?? ion was Equatorial-Skew type complex which was not accompanying with isomerization.

Physical properties of waterborne soft feel coatings for instrument panel were investigated. Soft feel coatings give warm and velvet touch for cold and hard plastic materials. Waterborne soft feel coating is composed with two parts. Part A contains polyester polyurethane dispersion (PE-PUD), OH-functional water dispersible polyurethane resin (PC-PUD) and OH-functional water dispersible alkyd resin (OH-PA). Part B contains hydrophilic hexamethylene diisocyanate trimer (HHDI). Soft feeling of coated panel was related with the amounts of PC-PUD and OH-PA. The physical properties of coated panel could be controlled by the NCO/OH ratio from Part A and Part B. Soft feeling was enhanced with relevant to PE-PUD content but the content of PE-PUD was limited because of weakening of coated film strength. For excellent touch and good property, the optimum composition of soft feel coat was PC-PUD(30%) and PE-PUD(20%). The results from all reliability tests satisfied soft feeling, scratch, chemical resistance and fogging.

The objective of this study is to integrate reliability analysis into shape optimization problem using the evolutionary structural optimization (ESO) in the application example. Reliability-based shape optimization is formulated as volume minimization problem with probabilistic stress constraint under minimization max. von Mises stress and allow stress. Young's modulus, external load and thickness are considered as uncertain variables. In order to compute reliability index, four methods, i.e., reliability index approach (RIA), performance measure approach (PMA), single-loop singlevector (SLSV) and adaptive-loop (ADL), are used. Reliability-based shape optimization design process is conducted to obtain optimal shape satisfying max. von Mises stress and reliability index constraints with the above four methods, and then each result is compared with respect to numerical stability and computing time.

As the aging population of the world grows, senior-friendly foods are becoming increasingly popular. In this study, the quality characteristics of domestic commercial senior-friendly foods were investigated and compared to the standard specifications of the Food Code and KS H4897. Herein, 18 samples of domestic commercial senior-friendly foods were utilized to analyze their appearance, physical properties (hardness and viscosity), nutritional value (protein, vitamin, mineral and dietary fiber), digestion rate, and hygiene indicator bacteria. When compared to the hardness standards of the Food Code all 18 samples were found to be satisfactory; however, when compared to the nutritional standard (at least three types of nutrients must be above the minimum), only five products, HG-7, DW-1, PS-1, OH-1 and OH-2, were found to be satisfactory. In addition, when the 18 samples were compared to the Korean Industrial Standard (2020), all 18 products were found to be satisfactory for physical properties and hygiene standards; furthermore, all samples, excluding HB-2, were suitable for nutritional standards (at least one type of nutrient must be above the standard).

The aims of this study are the characterization of runoff from nonpoint source, the analysis of the pollutant loads and an establishment of a management plan for nonpoint source of Okcheon. For this purpose the basin of the stream So-okcheon was selected to the investigated. During the period from May 29 to July 21 in 2003, the water automatic sampler system has been installed in Okkagkyo and parameters such as SS, COD, TOC, TP and TN were analyzed. The pollutants of nonpoint source seem to be washed out along the stream water in the beginning of rainfall, remain in water and cause the stream pollution. The runoffs during heavy rainfall, especially, much higher concentration of SS than those during dry period. With respect to the annual loading of pollutants of the nonpoint source, the COD was 124 ton/yr, TOC 396 ton/yr, TN 1,429 ton/yr and TP 4.2 ton/yr in the year 2002. With respect to the pollutants loading of the nonpoint source, the COD was 375 ton/yr(95% of the total COD loading of 394 ton/yr), TOC 844 ton/yr(96% of the tatal TOC loading of 876 ton/yr), TN 1,985 ton/yr(96% of the total TN loading of 2,062 ton/yr) and TP 37.1 ton/yr(92% of the total TP loading of 40.3 ton/yr) in the year 2003.
