This study is proposed to research the rural clothing, dietary and housing style of living in order to adapt a basis which is supposed to improve the quality of rural life. The sample in this research comes from Daehang 1 Li, Bubuk Myun, Miryang Gun, Kyungnam, and the results are as following; Generally rural housewives are unconcerned with fashion or its information, instead, they care for the casual wear which represents economic and active life style. Because of their financial problems, inpurchasing, they spend only a small money without plan. When they launder Clothes, they use washing bat and pannel which is easy to break fabrics, and they ineffectively use to dry it by hands twisting. The total food intake per person in a day is 1170.6gram, and all nutrients intakes except fat and calcium exceed the recommended dietary allowances. But 90.3% of the food intakes are plant food, and the average food items taken per day per househod is 11.9items which are not so various, which represents the shortage of the nutrient quality. Both the nutrition knowledge score and the food habit score are very low. Therefore, in order to enhance the quality of clothing and diet in rural life, they need to learn clothing and nutrition management for their enlightment. The most comprehensive type of farmhouse site plan take the shape of ㄱ and ㄴ, and for the most part main building is the floor plan which includes 3-4 spans in front of the change from the type of traditional house, throught the revised one, to the type of newly built house. In main building of the farmhouse, kitchen, Kunbang and Chakunbang are extended to their real space, and both utility and the bathroom are added to build, and Malu is transformed into the living space.

The study analyzed the heat losses and the building energy efficiency grade by the energy simulation using the ENERGY# and ECO2 programs for the three types of Standard design of rural houses. It was calculated the energy efficiency rating by the ECO2 program for the rural housing standard design, and the energy demand and the energy consumption by each factor were compared and analyzed. And it analyzed energy consumption by element of each house by ENERGY # program. As a result, first in the evaluation of the energy efficiency grade of buildings by the ECO2 program, the rating for primary energy requirement for the housing newly built by the standard design of rural house is expected to range from 2 to 4 with 189.3 to $238.7kWh/m^2.a$. Second, the energy loss of each part of standard design of rural housing occurs in the order of ventilation 39%, window 33%, outer wall 14%, roof 9%, bottom 5%, and energy loss through ventilation and window occurs more than 70%. Third, the most beneficial effects on the energy efficiency grade is obtained the lowest grade of all three types by 2 when the lowering of the window and door heat transmission rate and the lowering of the light density, and the heat exchange ventilation device is not installed. Fourth, in the standard design of rural housing, the energy demand is occupied by heating > hot water > lighting order, and the order of the weight is changed in order of heating > lighting > ventilation > hot water. Fifth, building energy efficiency assessment system needs to establish policy for fixing rural housing energy as a practical device to ensure energy performance and quality.

The objective of this study is to find out the recent trends of hanok design based on 58 hanoks appeared in architecture magazines in the last 10 years. The cases are analyzed in terms of location, size, building form, spatial organization, material, roof form, and the ceiling form of living room. The consequences of this study is as follows; Most of the recent hanoks are built in rural area (91.4%), which shows the hanok is not accepted as an urban house type. Hanoks tend to be built in 2 stories whose 2nd floor is smaller than the 1st floor. (34.5%) The preferred size is total floor area of $99.2{\sim}165.2m^2$ (62.0%), 3 rooms (46.6%) with a traditional ondol room (60.3%). The buildings with ㄱ-shape (43.1%) and linear-shape (27.6%) are preferred, and the compact plan type similar with apartment house appears (13.8%). In the roof design that greatly influences the appearance of building, the traditional design factors such as half-hipped roof (55.2%), double eaves (27.6%), and eaves curve tend to be sustained. In terms of spatial organization, most of recent hanoks have double-layed plan (74.2%). The living room mostly has separately defined space. (82.8%) The indoor and outdoor tend to be connected by a narrow wooden veranda (39.7%), while some cases don't have any wooden floor space (48.3%). The entrance is adopted as an important spatial element in front part of building (75.9%), and it influences the appearance of building. The living room, the counterpart of the wooden floor hall in traditional hanok, and kitchen tend to be interiorized. In terms of material, the cement roof tile and red clay brick are preferred. Consequently, the walls of recent hanoks have the image of brick structure rather than the wooden frame structure of traditonal hanok.

Ham-ra is a village that belongs to Ham-yuel Ri, Ik-san city and also known as the village where 4 millionaire modem age rich farmer households are residing in the center of the village. Originally, central point of the village was Gaeksa and Hyanggyo that is in Suodong, but early 1900s, rich farmers found new Places beside Suodong and built large-scale houses and around it, houses of tenant and commercial places were formed and became the new center of the village. Therefore, Ham-ra village shows well about the changes of the traditional village in the end of Chosun Dynasty aspect that of existent village space according to rich farmer's growth. Especially, the large scaled Korean traditional houses which were built newly in the year between 1917 to 1939 shows main road and Natural stream surrounding the village which are not found in any other village. 3 rich farmers (Lee Bae-won, Jo Hae-young, Kim An-gyun house) and Lee Jib-cheon's houses built a large scaled Sarang-chae and An-chae to compete and to show off there wealth. This residing imitated High-classe house yet accommodated social changes and through a voluntary experiment, is expressing modernity of Han-ok very well. Similarity and creativity in residing form appears well in buildings similar time and village. This research analyzed space composition change of the village and characteristic of Architecture who appear at modern process of typical farmer houses which make a strong resolution to Ham-ra hereupon.

The present study was designed to examine the concentrations, emission rates, and source characteristics of a variety of volatile organic compounds (VOCs) in 30 newly-constructed apartment buildings by measuring indoor and outdoor VOC concentrations over a 2-year period. For comparison, seven villa-type houses were also surveyed for indoor and outdoor VOC concentrations over a 3-month period. Indoor and outdoor air samples were collected on Tenax-TA adsorbent and analyzed using a gas chromatograph (GC)/mass spectrometer system or a GC/flame ionization detector system coupled to a thermal desorption system. The long-term change in indoor VOC concentrations depended on the type of VOCs. Generally, aromatic (except for naphthalene), aliphatic, and terpene compounds exhibited a gradual deceasing trend over the 2-year follow-up period. However, the indoor concentrations of the six halogenated VOCs did not significantly vary with time changes. Similar to these halogenated VOCs, the indoor naphthalene concentrations did not vary significantly with time changes over the 2-year period. Unlike the halogenated VOCs, the indoor naphthalene concentrations were much higher than the outdoor concentrations. The indoor concentrations of aliphatic and aromatic compounds were higher for the villa-type houses when compared to those of apartment buildings. In addition, four source groups (floor coverings and interior painting, household products, wood paneling and furniture, moth repellents) and three source groups (floor coverings and interior painting, household products, and moth repellents) were considered as potential VOC sources inside apartment buildings for the first- and second-year post-occupancy stages, respectively.

본 연구에서는 간헐적으로 발생되는 고농도의 NO를 효율적으로 제거할 수 있는 혼합 공정으로 선택적촉매환원(Selective Catalytic Reduction, SCR)과 활성탄소섬유(Activated Carbon Fiber, ACF)흡착이 결합된 신 개념의 공정을 설계하고 특성을 고찰하였다. NO를 흡착한 ACF에 열과 진공을 동시에 가하여 재생 실험을 수행한 결과, $140^{\circ}C$에서 600 mmHg의 진공으로 탈착하였을 때 가장 높은 재생효율을 보였다. SCR공정에는 상용촉매를 사용하였으며, 반응온도 $300^{\circ}C$, $NO/NH_3$몰비 1.0인 조건에서 실험을 수행하였다. ACF 재생공정에서 발생한 NO를 SCR공정으로 처리하였을 경우 98%의 매우 우수한 제거효율을 보였다. 그러나 지속적으로 유입되는 300ppm의 NO와 ACF에서 탈착되는 NO를 기존의 SCR공정에서 동시에 처리하였을 때 약 1분간 고농도의 NO가 배출되었다. 따라서 ACF의 재생시 발생하는 고농도의 NO를 기존의 SCR공정에서 병행처리할 때는 탈착속도를 조절하거나 고농도로 배출되는 짧은 시간 동안 $NH_3$농도를 높여서 주입할 필요가 있으며, 소규모의 SCR공정을 추가로 설치하여야 한다. SCR과 ACF를 결합한 공정을 이용하여 NO를 처리하였을 때, 간헐적으로 2배의 농도를 가지는 NO가 유입되어도 80% 이상의 탈질 효율을 가지는 공정의 구현이 가능하였으며, 반복 사용에도 활성이 유지되어 안정적인 운전이 가능함을 입증하였다.

In this paper, the test results of the combustion for 2 IAFR lean fuel models are described. The need for the low emission combustor has been issued from the concern on the increase of green house and the destruction of ozone layer. To evaluate the flow and combustion performance of newly designed 21AFR lean modules, the hydraulic tests in stereolithographic airflows models, the low pressure combustion tests in three injectors model for weak extinction and ignition and the high pressure combustion tests in single sector for NOx, SAE and efficiency are performed. The low pressure tests reveal that the governing parameters in weak extinction and ignition at atmospheric condition are prefilmer length, swirl flow rotation direction, secondary swirl angle and flow split. As a result of combustion test at high pressure, the efficiency and smoke level are satisfied with performance targets, but EINOx of 17.8 is higher than target value of 13.1 The high pressure tests show that the main parameters influenced on NOx are primary swirl angle, swirl flow rotation direction, heatshield exit angle and liner mixing hole location.
