In multifiber all-optical networks, optical amplifiers are used for amplifying multiple optical signals with different wavelengths in fibers. An optical amplifier operates when any of lightpaths passes through it. Therefore, it should simultaneously amplify as many lightpaths as possible for efficiently utilizing its power. This paper proposes a dynamic lightpath establishment scheme considering the use efficiency of the optical amplifiers and the depletion of the wavelength resources in multifiber all-optical networks. The proposed scheme provides a routing and wavelength assignment strategy that reduces both the power consumption of the optical amplifiers and the blocking probability of the lightpath establishment. Through simulation experiments, we demonstrate the effectiveness of the proposed scheme.

The food life of Korean people during the establishment of Republic of Korea and the Korean war was reviewed. After liberation in 1945, the division of South and North Korea, the establishment of the governments, and the ensuing Korean War made Korean society extremely chaotic and transformed. Consequently, data on Korean dietary life during this period (1945-1960) are scarce and unreliable. The author tried to reveal the food situation and health and nutritional status of Koreans during this period by examining the data released by the US National Archives and other review books. Regarding the nascent period of the food industry after the Korean War, data from the recent 50-year history of the Korea Food Industry Association has been compiled.

With a purpose of finding out the effects of phosphatic fertilizer application at the grassland establishment and management on the dry matter yield and quality of grasses, a field experiment was arranged with four treatments as a randomized complcte block design and lasted from September, 19 89 to October, 1991 in hilly area near Suwon. The results obtained are summarized as follows: 1. As a early plant growth. winter hardiness. growth vigour and coverage of grasses of the plots with phosphatic fertilizer were better than those of the plots without $P_2O_5$. and the effect of application at the management was much better than that at the establishment of grassland. 2. The effect of phosphatic fertilizer on DM yield of legume was higher than of grass. Total DM yield with phosphatic fertilizer at the only establishment (5.688 kg/ha). at the only management (8.014 kg/ha) and at both the establishment and management of grassland (1 1,082 kg/ha) was much more increased by 38, 95 and 169% than that without phosphatic fertilizer (4.1 19 kg/ha), respectively. 3. The chemical component of crude protein and crude fat with phosphatic fertilizer was a little higher, on the other hand, content of NFE was lower than that without $P_2O_5$ fertilization, but the contents of crude fiber and crude ash did not tend to differentiate between treatments. 4. Production of encrgy(TDN, StE and NEL) with phosphatic fertilization at the establishment and the management of grassland was appeared to increase by 34 to 390h and 72 to 99% than that without $P_2O_5$, respectively. Production of curde protein with $P_2O_5$ tended to be similar to production of energy.

Vivienne Westwood could be placed in a unique position in the contemporary fashion design. She has never belonged in a core group of mainstream fashion designer but not been always in an outsider position. She got from mainstream fashion designer circles enormous appreciation, even established fashion industry was influenced by her fashion design. She began her fashion design with rebellious T-shirts like 'destroy' T-shirt, chicken-bone T-shirt, and nipple-zipper T-shirt, all of which revealed her disgust against establishment. All these T-shirts testify her total negation tendency in her youth. However, she did not continue to keep such a kind of total negation attitude against establishment In 1980s she changed her political attitude towards establishment, and this change also found a reflection in her fashion design. In her pirate-collection the dark image of her fashion in the 1970s changed into a totally different bright image with full of gold colour. Although this collection had radiated brightness, it contained still outsider character from mainstream fashion design. The following fashion design in 1980s and 1990s evolved further on the line of Pirate-collection, but they continued to contain certain outsider characteristics. Vivienne Westwood kept some kind of anti-establishment attitude, and this attitude more or little came to the surface of her design. She was always political and critical to the establishment. In 2005, in her 64, she designed a liberty T-shirt, which showed her political attitude and her engagement in social issues. Also it showed the change from the early total negation to the constructive critical affirmation. In this paper the relation between the fashion design of Vivienne Westwood and her political attitude and the influence of her political attitude to her fashion design is analyzed.

This study postulates a partial mediation model(study model I) and a whole mediation model(study model II) to examine the effect on endogenous rural development of local innovation capability strengthening in the local industry promotion project, the establishment of promotion system, and the revitalization of local economy. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0 and AMOS 5.0. The results showed that in the partial mediation model, the local innovation capability strengthening had a significantly positive effect on the establishment of promotion system, the establishment of promotion system had a significant effect on the revitalization of local economy, and the revitalization of local economy had a significant effect on the endogenous rural development, while the establishment of promotion system and local innovation capability strengthening didn't have effect on the endogenous rural development. In the whole mediation model, the local innovation capability strengthening had a significant effect on the revitalization of local economy, the establishment of promotion system on the revitalization of local economy, and the revitalization of local economy on the endogenous rural development. According to the verifications of study model I and II, the endogenous rural development is achieved after the revitalization of local economy through the establishment of promotion system and the local innovation capability strengthening. From these results, this study presents suggestions, limits of study and directions in the future study.

Due to limited supplies and expensive importing costs, it is a goal to replace overseas peat with local soil amendments in turf industry of Korea. The study was initiated to compare the performances of five domestic and imported organic soil amendments (OSAs) on establishment characteristics and to provide basic information for root zone composition on sports turf design and construction. The study was conducted in Kentucky bluegrass (Poa pratensis L., KB) under greenhouse conditions from March to June in 2008. A total of 25 treatments of OSA + sand were prepared. These amendments were Berger Peat (OMA), Eco-Peat (OMB), G1-Soil (OMC), Premier Peat (OMD), and Supersoil I (OME). Significant differences were observed in establishment vigor, seedling emergence, and top growth. Results varied depending upon the type of OSAs and their rates in rootzone mixtures. OMA reached over 70% in establishment vigor in 5 WAS (weeks after seeding). OMC produced a maximum vigor of approximately 60% in 6 WAS. The OME amendment, however, showed poor performance lower than 30% in establishing KB turf until 8 WAS. There were considerable variations of top growth, being 3.8 to 14.5 cm. Greater differences in top growth resulted from OME mixtures. Shoot growth orientation in KB is also influenced by OSAs. In general, optimum mixing rate was considered as 10 to 20% for establishment vigor and 20 to 40% for top growth. Considering overall responses to establishment vigor, seedling emergence, and shoot growth, both local OMC and overseas OMD are considered as the useful soil amendments applicable for sports turfs. Domestic OME amendment would be applied for a low maintenance turfs such as rough and utility areas due to greater shoot growth. Information on these amendments would be of practical use for sports turf design and construction. Repeated experiments and field performance test are required to evaluate these OSA effect on other major turfgrass species and also to determine local OSA as imported peat substitute.

In spite of simple and cheap cultivation method, water broadcast-seeded rice demonstrates uneven and unstable seedling establishment per unit land area and requires more herbicide and labor-input for weed control. Three experiments were conducted in a phytotron at 18$^{\circ}C$ to evaluate the adaptability of seed-mat mulching cultivation technologies in water seeded rice for the uniform seedling establishment and the inhibition of weed occurrence without herbicide application. Five different kinds of mat with different mesh sizes and fabric properties were tested. The emergence of rice was the highest in Lawn-mat treatment, being comparable with the control, in which seeds were sown without mat. The Lawn-mat also exhibited the lowest mat tension. Mat tension may influence the emergence of rice. And once it was soaked in water, it didn't maintain its original shape any more. The emergence rate of rice was the lowest in Safer-mat treatment. In Lawn-mat treatment, which was the most effective for rice emergence in the first study, the differences of emergence and seedling establishment of rice depending on the seeding position (upper, beneath, and between mats) treatments were negligible, while they were higher in dry seeds than in pre-germinated seeds treatment. The emergence as affected by the kinds of mat also showed the same trend when tested using barnyard grass. Depending on the kinds of mat, the inhibition effect of weeds was the greatest in Safer-mat and the poorest in Lawn-mat. These results strongly suggest the possibility that the uniform seedling establishment and weed management without chemical could be achieved simultaneously by seed-mat mulching through the combination of effective mat for the emergence of rice and another efficient mat for the inhibition of weed occurrence. This possibility was also tested in the field.
