Costumes of Song Dynasty developed after the patterns of the Tang. The rise of idealist philosophy in the Song Dynasty had a great impact on the life of the people, Under the influence of this ideology, people's views on aesthetics changed considerable. In architecture, for example, white washed walls and black tiles came into fashion. balustrades, pillars and roof beams were left unpainted so as to retain the true colour of he wood. In painting, also, simplicity and delicacy were valued, and the preferred medium was ink or light colours. The desire for simplicity was even more evidently reflected in clothing and related adornment, as public opinion was against excessive display in dress. Consequently, the clothing of the Song Dynasty was quite reserved and conservative, with fewer variations and quieter colours, thus conveying a feeling of simplicity and naturalness. Compared with the dress of Tang, the dress of the Song Dynasty had other variations. Therefore women's dress of Song was also reserved and conservative, with fewer variations and quieter colours, simplicity and naturaliness.

A series of monoazo disperse dyes based on 2-amino-4-phenylthiazole was prepared using various N,N-dialkvlaniline derivatives as the coupling component. The dyes were characterized by IR spectral studies, visible absorption spectroscopy and elemental analysis. The dyeing performance of these dyes was assessed on cellulose triacetate and nylon fibers. These dyes were found to give a wide range of colour shades varying from bright red to royal blue with very good depth, brightness and levelness on fibers. The dyed fibers showed good to very good light fastness and very good to excellent fastness to washing, perspiration, rubbing and sublimation. The dyebath exhaustion and fixation on the fibers were found to be very good.

In order to study the reproductive physiology of Sand ell(Hypoptichus dybowskii) catched at kangwon-do, Wooamjin Bay, spawning and egg development were investigated in April and May, 1996. The observed spawning period was from the middle of April to the end of May with the water temperature above $8^{\circ}$C. Body size and colouration were distinguished between male and female. The type of testicular structure is lobular, and the ovary is a pair of sac-sahaped covering with a fibromuscula capsule and comprising a mature egg of average 86. The unfertilzed egg are demersal and adhesive, and their diameter were 1.65-1.95 mm. the colour of yolk is light yellow and contained a lot of tiny oil globules. The average spawned egg was 62 in sargasso weeds. Hatching was observed in 12 days after fertilization with the water temperature of 14 ${\pm}1^{\circ}$C. The average size of larva after hatching was 6.85${\pm}$0.23mm in total length, and larva were containing yolk including globule.

The constraints of traditional fish drying in Bangladesh have been reviewed and an effective solar fish dryer was developed with the small-scale processors and fishermen using locally available cheaper materials in order to dry fish in coastal region. After successful field testing, new solar dryer was demonstrated within the community in 3 different locations of Cox's Bazar for several batches of operations in each location from late September to March and found very effective in terms of architectural suitability, operational feasibility, technical efficiency, out-put quality (good texture, colour, flavour and long storage time), user's acceptability, commercial viability and environmental adequacy. A simple cost-profit analysis was done with the community operated products, which indicates that the new solar fish dryers could be operated profitably in coastal regions where sun-light and air flows are abundant.

It is thought that the adsorption isotherms in dyeing of cellulose by the direct cotton dyes are consisted of combined type of Langmuir and Freundlich as the opinion of Fujino, et al;$[D]_F=ab[D]_S/(1+b[D]_S)+k[D]_S$where a,b,k; constants, $[D]_F$; dye adsorption on the fiber, $[D]_S$; dye concentration in the bath. This means that the dyes adsorbed in cellulose present in the state of partly mono molecular and partly aggregate; the characteristic fading order curve will be expressed as the combined system of uniform particle size distribution and assumed that the slope of the theoretical models of Baxter, et al., and assumed that the slope of curve will be changed near the point of a, the saturation value of Langmuir isotherms in the above equation. Firstly, the theoretical fading rate curve was treated with small colour difference as the one step of experimental of above consideration.

한국산 나자식물 6개과에서 대표적인 1종씩을 선정하여 수피의 특징을 형태 및 해부학적으로 조사하고 기재하였다. 수피를 인위적으로 조직단위로 간주할 경우 수피의 색, 두께, 내수피와 외수피의 두께, 확장조직의 유무 및 발달정도, 조피내 주피의 층우와 주피의 층수와 주피의 구성요소들의 두께, 2기 사부지역 각 구성요소들의 배열양상과 점유면적 비율 등은 종류에 따라 차이를 보였다. 또한 보강세포의 형태와 사세포의 사역 등도 앞으로 상세한 조사가 수행될 경우 비교형태학적 연구에 매우 가치있는 정보를 제공할 것으로 생각되었다.

본 연구에서는 포도송이를 절개하지 않고 광학적인 방법으로 당도를 측정하였다. 광원으로는 $615{\sim}635nm$ 파장 대역의 LED를 사용하였다. 포도의 당도는 안토시아닌의 분포량에 의해 결정되는데 적포도의 경우 적색이 강할수록 안토시아닌이 많이 분포되어있다. 측정 결과 적색을 많이 띠는 적포도의 경우 광 강도가 낮은 것을 확인하였다. 또한 광학적인 방법으로 측정된 광 강도와 당도계로 얻어진 당도를 비교 분석하였다. 그 결과 포도송이의 당도에 따른 상대적 광 강도를 확인하였다.

Anthracnose fungi associated with soybean (Glycine max), small red bean (Vigna angularis), and green bean (Phaseolus radiatus var. aurea) were compared with respect to cultural characteristics, morphological aspects, and pathogenicity. From the legumes, four different species of Colletotrichum were identified based on their morphological characters : C. truncatum, C. destructivum, C. trifolii and C. gloeosporioides. Colonies of Colletotrichum spp.on culture media varied in colour and growth habits depending upon the media and isolates. In general, formation of conidia, setae, and perithecia on water agar leaf medium was better than that on potato dextrose agar medium under near ultraviolet light. In cross inoculation tests, isolates of C. truncatum, c. destructivum, C. trifolii and C. gloeosporioides could infect soybean, small red bean, and green bean at different growth stages. There were some differences in pathogenicity or susceptibility depending on crops tested. C. truncatum was the most virulent and major pathogenic species among the four species.

This article reports improved corrosion resistance and adhesion of electro-paint (E-paint) with fluoride conversion coating (FCC) on AZ31 Mg alloy for the first time. These improvements were observed in comparison to chemically polished samples with no chemical conversion coating and samples with cerium conversion coatings (CeCC). FCCs were prepared in a hydrofluoric acid (HF) solution for four different times; 10, 30, 60, and 120 s. The colour of the samples changed from light gold to brown with increasing immersion time, indicating the formation of thicker FCC coatings with increasing immersion time. The adhesion of the E-paint on FCC-coated AZ31 Mg alloy was tested after 500 h of immersion in deionized (DI) water. Salt spray test (SST) results revealed delamination of E-paint on the chemically polished sample, severe blistering on the samples with CeCC, but no delamination and no blistering on the samples with FCC.

LED has received intensive research attention due to its long life, high efficacy, fast response and wide colour availability, and has secured extensive application areas. However, LED chips within the modules convert only fraction of electric energy into light, and majority of supplied energy needs to be dissipated as heat, which challenges in the performance and life of the LED modules. IEC 62717 specifies the performance requirements for LED modules together with the test methods and conditions. The present study examined the influence of different design parameters on performance temperature through series of experiments and numerical simulations. The economic means to change the module performance temperature during the measurement of mandatory markings were suggested based on predicted cooling performances.
