This study was carried out to design, construct, and test a greenhouse monitoring system fur the environment and status of control devices in a greenhouse from a remote site using internet. The measuring items selected out of many environmental factors were temperature, humidity, solar radiation, CO$_2$, SOx, NOx concentration, EC, pH of nutrient solution, the state of control devices, and the image of greenhouse. The developed greenhouse monitoring system was composed of the network system and the measuring module. The network system consists of the three kinds of monitors named the Croup Monitor. the Client Monitor and the Server Monitor. The results of the study are summarized as follows. 1. The measuring module named the House Monitor. which is used to watch the state of the control device and the environment of the greenhouse, was developed to a embedded monitoring module using one chip microprocessor 2. For all measuring items. the House Monitor showed a satisfactory accuracy within the range of ${\pm}$0.3%FS. The House Monitors were connected to the Croup Monitor by communication method of RS-485 type and could operate under power and communication fault condition within 10 hours. The Croup Monitor was developed to receive and display measurement data received from the House Monitors and to control the greenhouse environmental devices. 3. The images of the plants inside greenhouse were captured by PC camera and sent to the Group Monitor. The greenhouse manager was able to monitor the growth state of plants inside greenhouse without visiting individual greenhouses. 4. Remote monitoring the greenhouse environment and status of control devices was implemented in a client/server environment. The client monitor of the greenhouse manager at a remote site or other greenhouse manager was able to monitor the greenhouse environment and the state of control devices from the Server Monitor using internet.

This study is for the Kyungduk-Dan(as a altar of Milsung-Daegun) and The Manun-Jae the characteristics(lay out and planning, window patterns, structure, materials) of the the Korean traditional house during the modern era. Before Manun-Jae was used for the house. The Kyungduck-Dan was constructed in August according to the Lunar Calender in 1927. The Manun-Jae(house for Ki-hun Kang, millionaire ) was completed in 1924. Modern Architectures brought to Korea with the bricks, the tiles, the flash doors, the plate grasses, the brass hardwares. These architectural material was used in positive. During the construction of Manun-Jae in 1924, it happened the architectural exchage among a korean, a chinese and a japanese constructor. Though using the air exhaust valve at the kitchen of Ukyung-Kak( old Anchae), it could be assume that the modern convenience and the improvement of residential environments was considered at that period during the construction of Manun-Jae. That construction was elected with the brick($222mm{\times}106mm{\times}50mm$), the chinese colored tile and plate glass such a modem materials. The new shape of the korean lattice window and the wooden flash-door with glass was used. In Ukyung-Kak, the Chan-Maru(service space) and the kitchen such as a service space or concise utility zone was organically connected. Especially, considered the domesitic activity and circulation, the western kitchen sink and the Chan-Maru(service space) was rationally placed. At the Manun-Jae and the Kyungduck-Dan, the architectural characteristic is that the new shape of windows was used. The lattice window at the Ondol room of Ukyung-Kak, was rgadually added the plate glass and the wood plate. The lattice window with the grid shape at kitchen of that building was adapted japanese grid lattice window in korea at that period. It is the sample that korean traditional house was typically influenced from the japanese resident culture. The Manun-Jae and the Kyungduck-Dan as the modern house kept the form of korean traditional architecture, and was partially adapted a modern characteristic space and modern architectural materials. During the japanese occupancy, these residence can be showed the transition in formally.

The purpose of this study is to clarify the spatial changes that have taken place in the main rooms (Anbang) and kitchens of traditional Utbangkkeokeum houses in Cheongju city, located on the central inland of Korea. These houses consist of a main house (Momchae) and a single-wing house (Nalgaechae), creating an ㄱ-shaped plan. The kitchen is in the front of the Nalgaechae, and the Anbang is at the rear. For the Momchae, the main hall (Daechung) is next to the Anbang, which is at the end of the Nalgaechae, and the room (Gunnunbang) is situated across from the Daechung. This study is based on the assumption that these houses have been conserved and altered from their original forms. As a result of alterations, many changes have occurred to the main room and kitchen spaces. The traditional main room is connected with two rooms (Utbang and Araebang), new standup kitchens are introduced, and floor heating systems are installed. The Anbang has maintained its sedentary lifestyle and the space for major daily activities such as sleeping and TV viewing. Also, TV viewing is a distinctive feature for residential purposes and the bedding is located in such a position that it is easy to observe any exterior movement for the elderly living alone. The layout of the standup kitchen has been altered to maintain the previous circulation, position and function of the entrance. Also, the kitchen and dining room were used together, and the size of these rooms has been partially increased from the original module in different ways for each case. The above findings suggest that Utbangkkeokeum houses of Cheongju city have been spatially changed while maintaining the previous lifestyle.

nZEH (net-Zero Energy House) is defined as a self-sufficient energy building where the sum of energy output generated from new & renewable energy system and annual energy consumption is zero. The electricity generated by new & renewable energy system with the form of distributed generation is preferentially supplied to electrical demand, and surplus electricity is transmitted back to grid. Due to the recent expansion of houses with photovoltaic system and the nZEH mandatory by 2025, the rapid increase of distributed generation is expected. Which means, we must prepare for an electricity-power accident and stable electricity supply. Also electricity charges have to be reduce and the grid-connected should be operated efficiently. The introduction of ESS is suggested as a solution, so the analysis of the load matching and grid interaction is required to optimize ESS design. This study analyzed the load matching and grid interaction by expected consumption behavior using actual data measured in one-minute intervals. The experiment was conducted in three nZEH with photovoltaic system, called all-electric houses. LCF (Load Cover Factor), SCF (Supply Cover Factor) and $f_{grid}$ (Grid Interaction Index) were evaluated as an analysis indicator. As a result, LCF, SCF and $f_{grid}$ of A house were 0.25, 0.23 and 0.27 respectively; That of B house were 0.23, 0.23, 0.19, and that of C were 0.20, 0.19, 0.27 respectively.

This article has an aim to study what kind of housing system our ancestors lived with during the Yi-Dynasty by analyzing the house-plan of upper-class society of that period since the house of lower-class was very insignificant as it has always been while the house of upper-class represented the period. With this study we can clearly see how we ought to go in the right direction toward the development of our Korean genuine housing by renovating and renewing those unreasonable points in our traditional housing system. It is firmly believed that we should-keep our own unique traditional lovely housing system for being destroyed by the whirl-wind of modernization and the demand of rationalism and efficiency-centered idea of the western mind. From this view point we think it is very urgent to see this matter correctly and find out the real way how we should do in order to keep our own good things for ourselves and make them preserved. This essay is divided into three parts as follows : 1. Thoughts on selecting the good housing area. 2. The aspect of housing reflected upon composing the house-plan. 3. The characteristic sentiments reflected upon the interior construction and decoration. We can find several characteristic points in the housing system of the Yi-Dynasty as follows : 1. In Korea, the thought of natural geography (Poongsu-seul), apart fro scientific view, which seems rather superstitious to us, modern young people, has been highly recommended by the people of our country from old days connected with the prosperity of our life. They also neglected about the social circumstances such as, market, transportation, and education, which are now considered as very important. They only put their concern on this natural environment which they called Poongsu. 2. In construction of house-plan, the house was not built for living with reasonable convenience, but for showing prestige of the upper-class people reflecting its social organization under the feudalism of the period. Furthermore, the most of the housework was done actually by those servants and maids of the house, and not the family themselves. The only concern for the upper-class people was to show off their authority, and so this sense of authority was revealed in the housing as well. 3. Both the outside appearance of the house and the interior decoration or the furniture are all very artistic and lovely. They were so refined and beautiful with their delicate taste which truly seem against our modern rationalism and uniformity.

The purposes of this study were to analyze the family life, farm wort and leisure satisfaction of rural wives in Chonnam district. 300 farmhouses were selected by stratified sampling from 20 Myon in Chonnam district, 283 wives were interviewed using questionnaire. The results are as follow : 1) The level of wives's value perception of agriculture was low. The level of satisfaction of family life was higher than farm and leisure life. The farm satisfaction is the lowest. 2) family environment variables(such as age, education, children number, yearly income, family type, the number of year of house built), variables connected with farm life(major type of agriculture, value perception of agriculture, underdeveloped cause, living period in farm), and variables connected with time use significantly influenced on the life satisfaction. To promote the satisfaction of rural wives various implications were discussed. (Korean J Human Ecology 1(1) : 66∼80, 1998)

Purpose: To evaluate the economic performance of grid-connected photovoltaic system in residential house, household electricity bill policy of Korea Electric Power Corporation (KEPCO) must be applied precisely, and market tendency and uncertainty of system also need to be considered. In this study, to evaluate the economic feasibility of PV system, we measured PV power generation and electricity consumption of six of Green home in Daejeon through web based remote monitoring system. Method: We applied Monte-Carlo simulation based on life cycle cost analysis, to reflect an uncertainty of main factor in economic feasibility evaluation of photovoltaic system. Result: First, with deterministic analysis, the difference of NPV of cumulative financial savings among households varied from -3,310 ~ 24,170 thousand won, portraying notably big range. Also the possibility of getting the same result was 50% when applying uncertainty. Second, the higher electricity consumption is, the more economic feasibility of photovoltaic system increases because KEPCO uses progressive taxation in household electricity bill policy. Third, The contribution to variance of electricity price increases in NPV varied from 98.5% to 99.9%. While the inflation rate and annual degradation contributed very little to none.

The networked home is connected to the external world using a high speed network. The devices inside the house are connected using a wired and wireless network. Acquiring the user data is an essential step for designing the user interface in user centered design. In networked home, the numbers of use cases are exponentially increased because connected use cases are considered. Because the user data for networked home are too complicated, they are acquired and analyzed by a structured methodology. We surveyed 40 people to acquire the context data home and analyzed by 5W1H (Who, Where, What, When, Why, How). We established a framework for the user data using tasks, user, time, space, objects and environment. The data for home context was structured by our framework. This framework makes simple the home context and is helpful for user interface design in home network.

Considering that rural village had evolved through a long-sustained effort of harmnization with nature, there should be the wisdom not only to reflect the level of rural resident's housing demand, but also to conserve the traditional characteristics of high-valuation in the modern rural housing. In Korea , standard design proposals of rural houses had been made public three times ; in 1972 , 1984 and 1995. so , firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through, the positive acceptance of residents' opinion living inthe houses built by standard design proposals in 1970 ~1980's, improved design principles and an alternative model were proposed , finally. The inner-space structed of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the " open system". In 1980s, the basic design principle changed to the 'closed system' in which the living room being the focus of indoor family life, and , in 1990s, progressively, therural housing developed to the high qualified type by the spatial enlargement and with increased equipements. However, this structural change of rural house brought about the problem of functional separatioon between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. conclusively in this study, newoly arranged "open system" was recommended , as a basic design principle for theinner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criterial was proposed as follows ; 1. The living room be directly linked to the front-yard and centrally placed, the addtional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The kitchen also be directly linked to side-yard and to livng room , for the convenience of farming activities and the shortening of path flow housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet and-bathroom , of which function would be for undressing of working clothes, quickwashing and ordinary working.nd ordinary working.

Julio Romano decorated the facade of his house in Mantua with a statue of Mercury to give expressions to his ideas on painting. Hereby the painter from Rome could show his home to the world as that of a painter. To be concrete, Mercury was the planet god to which visual artists belonged, and so was basically related to visual arts. In his role to deliver diverse features of art works Mercury could also convey concepts and emotions expressed in a picture to the viewer. The power of a painting to arouse certain emotions or move the mind of the viewer was further connected to the role of Mercury as the guide of the human soul. This function again related the Roman god to the characteristic of a portrait to present absent persons to the viewer. Above the statue of Mercury, a Lucian head of the god is seen, so that they together form the central axis of the facade. This seems to emphasize that the theme of the facade decoration was the powerful persuasive forces of eloquence. The two masks on the left could then refer to sources of eloquence, I.e. various beautiful expressions of a language and its generative process. On the other hand, the masks on the right could represent consequences of eloquence, for instance, prudence, evil effects which come about to imprudent listeners, and other influences on listeners. Finally, it would be useful to remind us of a line from On Architecture by Leon Battista Alberti. According to the humanist architect parts of a building which are seen from the outside, like a facade, should be appropriately designed, since the decoration of a house could play a significant role to enhance the fame and honor of the family and its fatherland. This theory of Alberti could have provided the foundation to the facade decoration of the Casa Pippi which proudly presented the profession of painting to the public in visual form.
