The survey of silkworm disease occurrence in autumn rearing season, 1984, was carried out and the results are as follows. 1. The percentage of diseased larvae in the current season was about 17%. 2. Among silkworm diseases, grassarie was predominant, as it took 38.5% of total diseased larvae, followed by muscardine which took 20.3% and flacherie was taken by 11.9% 3. The infection of silkworm larvae with pathogens occurred more at grown larva stages than at young larva stages. 4. The loss of cocoon yield was mainly caused by unsuitable climate conditions and agricultural insecticides applied in the rice paddy fields and fruit gardens near mulberry fields. The cocoon production also was reduced by the failure of silkworm disease control due to the incomplete disinfection of rearing rooms and tools.

This article is to review the concepts of Confucian Utopia in Chosun Dynasty by looking into a sample of Daksil Village in Bongwha area. Here are some of the investigation. 1. The spatial composition entities of Daksil Village are both Confucian and Tao elements. 2. The whole views are made up by placing the Taoist View(gardens) into the Confucianist view(village and Seowon) and by placing the Confucianist view(summer house) into the Taoist view(Valley view of Seokcheonjeong). Two worlds are integrated into one by including each other. 3. According to the theory of geomancy(fang-shui), Daksil has the shape of ‘Geum-Gye-Po-Ran (Golden chicken embracing eggs)’, which is considered to be a land of fortune. Conclusively, Confucianists in Chosen Dynasty adopted fang-shui details when they built a residence, while they put much importance on Confucian and Tao elements. Moreover, it is found in the records that “It is a good place to start a village if there are mountains and water near the residence.” The fact that Daksil village is located at a day's distance from Seowon-Seokcheonjeongsa-Village-Jaesil-Grave proves that the residential village is set at an ideal place.

Roof greening recently emerged to be an important issue of environmental policies in a city. To cover roofs of buildings with green vegetation gives chances not only to improve urban environmental function but also provides the opportunities of environmental learning and convenience for users in the building. This study aimed to give directions for roof greening plan to designers by acknowledging the relationships between ecological and utilizational effectiveness. 10 sites and 15 variables were adopted to measure the relationships. As a result, no positive correlations was found between them. One of the results in correlation analysis among variables, however, showed that the roof gardens have high utilizational effectiveness only when a green roof was made by focusing on ecological functions in addition to the concepts that will guarantee user's convenience such as accessibility, entrance and exit, facilities for convenience and learning. The results implies that a green roof has to be designed considering multi-functional effects. Correlation between species of vegetation and the number of daily users, average staying hours, and attending level for environment educational programs were not significant. These findings imply that when a green roof has to be take high utilizational effectiveness, both plentiful vegetation species and design concepts for users' convenience are should be considered.

The purpose of this study is to establish design guidelines for waterscape facilities of healing gardens in psychiatric hospitals. Data were collected through simulation and interview. The subjects included schizophrenic (n=42) and alcoholic (n=41) inpatients as well as medical staff personnel (n=40) at Maeumsarang Hospital. The results of this study are as follows: It was revealed that for all three groups the first preference was a natural flowing waterscape, and the second preference was a natural descending waterscape. The schizophrenic subjects had a greater preference for a static artificial waterscape and a descending artificial multistory waterscape than the other two groups. The alcoholic subjects preferred an ascending natural multistory waterscape. The analysis on the preference towards an ascending type and a descending type from the perspective of naturalness and complexity. Complexity had a greater influence than naturalness in the ascending waterscapes, and naturalness had more influence than complexity in the descending style waterscapes. Therefore, these factors need to be taken into consideration when designing either ascending or descending waterscape facilities. In general, the subjects preferred natural, dynamic and descending waterscapes to the artificial, static and ascending variety.

Shade affects turf quality by reducing light for photosynthesis. The shade tolerance of the tropical grasses, Digitaria longiflora and Axonopus compressus were evaluated against Stenotaphrum secundatum (St. Augustinegrass). The grasses were established under shade structures that provide 0%, 50%, 75% or 90% shade level for 30 days. A suite of leaf traits, recorded from similar leaf developmental stage, displayed distinct responses to shade conditions. Leaf length, relative to control, increased in all three species as shade level increased. The mean leaf extension rate was lowest in St. Augustinegrass (80.42%) followed by A. compressus (84.62%) and D. longiflora (90.78%). The higher leaf extension rate in D. longiflora implied its poor shade tolerance. Specific leaf area (SLA) increased in all species with highest mean SLA increase in D. longiflora ($348.55cm^2mg^{-1}$)followed by A. compressus ($286.88cm^2mg^{-1}$) and St. Augustinegrass ($276.28cm^2mg^{-1}$). The highest SLA increase in D. longiflora suggested its lowest performance under shade. The percent green cover, as estimated by digital image analysis, was lowest in D. longiflora (53%) under 90% shade level compared to both species. The relative shade tolerance of the three turfgrasses could be ranked as St. Augustinegrass > A. compressus > D. longiflora.

It may be said that ancient wild Chinese garden had been founded during Qin dynasty and completed through Han, Sui and Tang dynasties. At first used as hunting areas for kings, the ancient resort forests began to take forms of garden. They dug a pond in the garden and made a simulated mountains with the soil that came from the excavations for the pond and suc pavilions has Gyong, Ru, Gak etc. were built around the pond. The ponds were different in size from those in Korea, being of the lake-like size. they made three island in the pond, which were the islands of Taoist hermits with supernatural powers, called Bong-lae, Young-ju and Band-jang respectively. the traditional of making those islands began in the Qin era and were completed in the Han era, being descended to posterity as a traditional garden structure of 'three islands in one pond' garden style. Such style was brought to Korea and first appeared as Kung-Nam-Ji in Back-jae kingdom and then brought to Japan, becoming the tradition of constructing ponds from early Heian era. Those lake-like huge Chinese ponds constituted the core of ancient garden where various feasts took place. Such ponds were also placed at the center of the gardens and played the roles of feasting garden ponds. Through the above-mentioned studies of the ancient Chines garden, the origin of them and the influence of the ancient Chinese ponded garden upon those of Korea and Japan were investigated.

Nagaya is one of the traditional Japanese housing types in which multiple houses are attached together. In Nagaya, walls are shared by several houses but entrances are privately owned by houses. Nagaya consists of many wooden houses for common people located in parallel with narrow alleys between them. Nagaya was one of the representative housing types in Japanese architectural history. This research is to study the background of the origination of Nagaya in Japan, the characteristics of space and land planning, the features and causes of the changes in the space and land planning. In this research, we observed and analyzed unit plans of a block of gate-type Nagayas in Hanan, Osaka. The results are as follows. First, as the inner alleys(Roji) are closed, the number of entrances to each housing lot decreased from two to one since one entrance that used to be open to inner alleys(Roji) are permanently closed. Second, walls between streets and housing lots which used to be one of the outstanding characteristics of gate-type Nagayas are disappearing. Third, as the bathrooms are added to houses, the front gardens are being degraded to empty spaces or sometimes totally removed. Fourth, the space in the first floor of houses become family spaces, and that in the second floor is divided into private rooms for individuals.

Significant findings concerning the cause of the gardening revolution of the eighteenth century in England, its landscape style and contribution to a new style are concluded as follows: 1. The English landscape garden is regarded as a great revolution in the history of landscape architecture, and it was in the eighteenth century, in England, that garden and landscape first came together. 2. For at no time in history has there been such general interest in gardens and in the total physical landscape, so much writing and criticism and open debate. 3. Garden design did not become a definite art form in England until the eighteenth century. During the period it can be seen that there were developing three distinct types of garden, that is, the picturesque garden, the 'poetic' garden and 'abstract' garden. 4. Also developing was a new appreciation for natural forms and natural landscape, expressed in painting, poetry and garden design, and the landscape gardeners tried bard to malce country scenery look as though man had not had a hand in it. Eventually these open spaces contributed to a new type of spatial form development of naturalistic landscape style which is today taken for granted as a normal component of the landscape architect's palette.
