The vocabulary of modern grand hotels' interior designs reflects western design patterns, showing its nostalgia for modern architecture. And it also contains the trace of past designs implanted by others then, expressing the hardships of Korean history. Like this, the past architectural style distorted under the Japanese imperialistic rule has continued to exist until now without any significant changes, because there has been little effort to figure out the history of modern interior designs. And also there has been the lack of data and aesthetic descriptions about the modern interior designs that contain the historical nature of society. Therefore, this study will review the interior design of modern buildings, which trace back to the fawning of the Korean Interior Design. And it aims to understand the hotel interior's expressive characteristics and historical meanings by paying a particular attention to its lost parts. And it also alms to have a significant meaning in taking the first step toward a clue of the history of Korean modern interiors by systematically putting in order the ever-disappearing materials of modern hotel interiors.

Soilborne diseases pose a serious problem for mulberry cultivation during nursery plantation and established gardens, which cause severe loss in revenue generation of mulberry growers as compared to foliar diseases. Various soilborne diseases affect mulberry. Among them, root knot and root rot affect the established plantation resulting in severe loss in leaf yield apart from deterioration in leaf quality, which is a pre-requisite in successful sericulture to get the good quality of cocoons. Besides, stem-canker, cutting rot, collar rot and die-back, affect the initial establishment and survivability of mulberry plantation in nursery. The problem is difficult to handle, due to the complex nature of the diseases and also involvement of various biotic and abiotic factors. This is compounded by the occurrence of disease complex (especially nematode ＋ soilborne pathogenic microbes) in established mulberry gardens, which facilitates quick spread of the disease and enhance the plant mortality, resulting substantial loss in leaf yield. Therefore, prevention and timely control measures need to be taken up to protect the mulberry plants from different soilborne plant pathogens. In this review article, symptomatology, epidemiology, disease cycle and control measures of soilborne diseases of mulberry are discussed.

The sensorless control of high efficiency air compressors using a permanent magnet type synchronous motor as an oil-free air compressor is quite common. However, due to the nature of the air compressor, it is difficult to install a position sensor. In order to control the permanent magnet type synchronous motor at variable speed, the inclusion of a position sensor to grasp the position of the rotor is essential. Therefore, in order to achieve sensorless control, it is essential to use a permanent magnet type synchronous motor in the compressor. The position estimation method based on the back electromotive force, which is widely used as the sensorless control method, has a limitation in that position errors occur due either to the phase delay caused by the use of a stationary coordinate system or to the estimated back electromotive force in the transient state caused by the use of a synchronous coordinate system. Therefore, in this paper, we propose a method of estimating the position and velocity using a rotation angle tracking observer and reducing the speed ripple through a disturbance observer. An experimental apparatus was constructed using Freescale's MPU and the feasibility of the proposed algorithm was examined. It was confirmed that even if a position error occurs at a certain point in time, the position correction value converges to the actual vector position when the position error value is found.

The purpose of this study is to figure out visitor's attitudes for trail facilities in Gayasan National Park in order to provide the basic information for effective installation and maintenance of trail facilities. The questionnaire survey on two trails were conducted to 227 visitors on the way back home after using the trails. The use characteristics of two trails were a little different from each other, and the conditions of two trails were rated relatively high both in quantity and quality. By the evaluation of 5 types of trail facilities in Haein trail and 4 types in Baegun trail, The responses were noticeably positive about wood deck, log steps with stones and wood steps in Haein trail and about deck-type wood steps and log fences in Baegun trail from the point of three aspects; harmony with nature, resources conservation and user convenience. On the other hand it seems necessary to replace the steel steps of both trails with eco-friendly materials. So, from now on it is necessary for introducing the trail facilities in National Parks to apply the eco-friendly materials extensively and to upgrade the design aspects comprehensively of harmony with nature, resources conservation and user convenience

Gwanghwamun was dismantled and displaced to the east side of the palace, at that time, the Chosun Government General Building was constructed in the Gyeongbokgung palace. After the Korea war, it remained as a stonework as a result of the fire. In 1968, The Gwanghwamun came back in front of the palace. Then, why it was rebuilt in the 3rd Republic period? What was the reason for selecting concrete? Since the May 16 coup, the military regime had been utilized palace and surrounding urban space to show a visible practice of modernization. Attempting the combination of modern technology in the 1960s and traditional cultural property and reconstructing a city as a pretext called Cultural Heritage conservation was a typical mechanism of the 1960s. In this study, I start by assume that reconstructing Gwanghwamun(1968) was a part of project to change the surrounding urban space of Gwanghwamun than to preserve cultural assets. Two main contributions of the study are following. First, I collect availabe data on the reconstructing surrounding urban space of the Gwanghwamun and re-organize them in chronological order to make them as fragments of a map. Second, I analysis and identify the nature and phase of the Gwanghwamun reconstruction.

A numerical simulation for 11 February 1996 has been done to grasp main mechanisms of the occurrence of strong downslope winds near Gangnung area. The simulation performed by using ARPS (Advanced Regional Prediction System) showed that enhanced surface winds were not related with a reflection of vertically propagating gravity waves. Froude numbers were about 1.0, 0.4 and 0.6 for the atmosphere above Daekwanryoung and above a place located 220km upstream, and above another place located 230km downstream from the Taebak mountains, respectively. This suggested that as a subcritical flow ascended the upslope side of the Taebak mountains, Froude numbers would tend to increase according to the increase in wind speed, and near the crest the flow would become supercritical and continue to accelerate as it went down the downslope side until it was adapted back to the ambient subcritical conditions in a turbulent hydraulic jump. Simulated Froude numbers corroborated the hydraulic jump nature of the strong downslope wind. In addition, the inversion was found near the mountain top height upstream of the mountains, and it was favorable for the occurrence of strong downslope winds.

Clinical trials are experimental studies with human subjects in which various limitations and variables exist by their nature. As a preparatory stage for designing clinical trials in Oriental medicine, this study considers a virtual protocol to show guideline regarding tasks necessary when writing a trials protocol. Clinical trials have many difficulties in planning, procedure, and interpretation of results, and these may be influenced by various biases that are difficult to predict and eliminate. To deal with these issues, clinical trials need a collaboration between medical experts and biostatisticians from the beginning, through the entire trial, until the final analysis. Therefore, the first stage of clinical trials is to write out a trial plan among the experts in each field to derive the best design for the trial.

The purpose of this paper is to show that a shape pro-duced by natural factors such as weather, environments, etc., can be introduced into the emotion of a design, and to make a design process by planning a Korean image and characterizing its concept. Human beings, nature, man-made objects, and society have their own functions in an environmental structure. When all their functions are kept in working order, human beings come to discover orderliness out of which they can absorb pleasure. They cannot look into their own inside but they can trace back in their memories a variety of panoramic experiences which have been embed-ded onto their identity during their lifetime interactions with an empirical world. Children first acquire a way of cognition in the space, a comprehensive premise, connecting a specific place and an object of cognition. Such subconsciousness forms sky-lines of mountains, seas, and trees under the sky, and produces axis lines and beehived domes under the influ-ence of natural, cultural, and social factors, forming a folk culture. A subconscious composition of existential space is extended. A subconscious composition of existential space is extended to the areas of environmental design, product design, and fashion design. The development of a concept of place and space as a system is a necessary condition for discovering an existential foothold.

This study aimed at creation of bench design to be placed in the public spaces for the citizen who live in Jungnang-Gu. In Jungnang-Gu surrounded by the excellent natural environment like Jungnang-stream, Mangwoo Mt., Bongwha Mt. and Youngma Mt., there are many public places where a citizen can take a rest. Among the public facilities being in such public places however, the benches especially were installed so unplanned and disordered, even that they look unbalanced with the natural environment, though they need to play a meaningful role in park and walking paths. Hereupon this study intends to investigate the geographical environment in Jungnang-Gu and furthermore to develop the bench-design on the basis of the investigation. The concept of design lies in modern style of a bench matched up with the nature well and also taking the functional aspect for rest, in consideration of the public places utilized by the abundant natural greens. The environment-friendly timber, marble and metal were used here and the design with and without the back of a bench & the dimension for Korean people's figure were considered.

Hipp8ie style was introduced in 1960s when young generation's movement against industrial society and mass culture was spread. Its value was to go back to "Real and Pure Nature". Hippie originated from "Human Be-in" which was on-violent revolution held in sanfrancisco. American Hippie style was represented through freedom and love based on drug and psychedelic culture which were created by the young generation who were against traditional esthetic value as well as the moral and material value. However, Hippie style was represented differently in France. The privilege classes such as artists who were interested in surrealism, art negro and primitive culture, the intelligentsia like Montparnass in Paris, accepted Hippie style faster than ordinary people did. therefor, Hippie style in france was represented as an esthetic mode not a symbol of anti-culture and anti-policy. The general public imitated the style of the privileged classes and coordinated their style according to their personality without any standard such as blue jeans, ethnic, psychedelic, mini, mods, beatnik, etc. Yves Saint Laurent who was influenced by hippies led the mode of Paris to introduce "Africa", "Saharienne", "Pathwork". therefore, in 1960's fashion in Paris, everything was possible because of too many changes in fashion and refusal of accepting vogue.
