The case study looks into the case of the "extreme" market segmentation strategy of company L with its top luxury windows and door brand "Lonchel". Company L has long enjoyed a leading position in the Korean windows and doors mass market. However, it went against their already well-established flagship brand and created a completely new one called "Lonchel", pursuing an extreme market segmentation strategy focusing on the small niche market of highest-income customers exclusively. The strategy has turned out to be successful and the company has gained long-lasting competitive advantages. In this vein this study analyzes the market environment in which the top-tier brand "Lonchel" appeared, the concept of the extreme positioning and the smallest viable market, the characteristics of target customers, the company's analysis of and response to them, and the analysis of products to meet their needs. The brand operation plan and promotion will be also reviewed. Through this, we intend to draw implications related to the extreme positioning strategy that a company may pursue in a target market of small groups of people.

The purpose of this research is revise the value yield to compensate of measure the difference between computer simulation and the measurement value on the two methods which can calculates thermal performance. The way is need to understand about thermal performance, air tightness, simulations and comparisons of analysis to influence the value of each identified. The opening type of the windows and doors to be used at the analysis are T/T, L/S and SL Different condition of the windows and doors excluded except the opening type. Each of the four samples was selected by the way of opening. Result of the analysis of the difference between measurement and simulation are that T/T approach 5.3%, L/S approach 15.7%, SL approach 21% and the more air-tightness guarantees less difference of the numerical value. Each compensation value calculates by the correlation regression analysis and the air-tightness data. After the compensation of the resulting difference in T/T, L/S, SL indicate 5.4%, 2.5%, 1.0% respectively.

Up to now, most the fenestration industry is consisted of glazing and window frame in Korea. According to the Fenestration Energy Consumption Efficiency Rating System and Energy Saving Design Standards of Buildings, u-value of fenestration is defined as the value of calculation with glazing and frame. For this reason, when applying for a building permit, in most cases, the official approval test report of the set of windows and doors is used. Nevertheless, in windows construction progresses, most construction manager take delivery of the glazing and frame separately. For those reason, windows and doors are constructed regardless of the report of the Fenestration Energy Consumption Efficiency Rating System in most construction fields. From now on, the research of the connection method between reality of policy and reality of construction fields should be carried out.

본 논문에서는 모바일 환경에서 원격으로 창호시스템을 감시하고 제어하기 위한 새로운 관제시스템을 개발한다. 이를 위해 창호개폐기, 게이트웨이, 관제서버 시스템을 각각 설계 구현한다. 여기서 창호개폐기는 개폐를 위해 직류모터를 이용한 구동장치와 상태정보를 모니터링하고 개폐제어 정보를 전송하는 모션제어장치로 구성된다. 게이트웨이는 창호의 현재 상태정보와 제어정보를 전송하기 위한 유 무선 통신 인터페이스로 TCP/IP와 CDMA 프로토콜을 지원한다. 또한 관제서버는 창호 제어정보의 저장과 처리를 위한 프로그램, 다양한 상태메시지의 처리를 지원하기 위한 미들웨어, 그리고 개폐 상태를 감시하여 시스템을 원격제어하기 위한 DB로 구성된다. 특히 스마트폰과 같은 모바일환경을 지원하는 응용소프트웨어와 웹기반 사용자 인터페이스도 함께 개발되었다. PC 및 스마트폰 기반 개발된 창호 시스템의 시작품을 대상으로 동작성능, 환경영향, 구동 내구성, 그리고 동작오율 각각을 2개의 공인기관에서 시험한 결과, 우수한 성능이 있음을 확인하였다.

Nowdays the apartment is a main type of modernized residential buildings. According to the improvement of construction techniques and functions of windows and doors, recent apartments are enhanced air tightness of windows, doors and building envelopes. As Infiltration is decreased and natural ventilation is reduced, energy could be saved in winter. However, indoor air quality is bad. The air Infiltration of a building could be enlarged by physical actions, such as building designs, constructions and reduction of air tightness which is caused by aging. This research analyzes and measures with KNS-4000P (Sapporo air tightness measurement) the air tightness of the high rise apartments which is recently constructed and not occupied yet. With depressurization method, the KNS-4000 installed on the window and the indoor air-leakage was measured. At that time, Air come out from the edge of the windows and doors because of the pressure differences between indoor and outdoor. We measure the amount of the air as effective air leakage areas. This method of depressurization takes less time to measure than other methods and is less affected from other conditions. We measured infiltration of total 56 household, 29 households S apartment (total floor area : $64.42m^2$) in Balan and 29 households D apartment(total floor area : $78.21m^2$) in Chonan. As a result of the field measurements at October 2003, normalized leakage area of D apartment in Cheonan was $2.05cm^2/m^2{\sim}3.49cm^2/m^2$ (average: $2.77cm^2/m^2$) and normalized leakage area of S apartment in Balan is $1.23cm^2/m^2{\sim}1.68cm^2/m^2$ (average: $1.5cm^2/m^2$).

Seonjeong-jeon, the semi-great hall in Changdeok Palace, was constructed in a highly formal and conservative style and accommodated official ceremonies. However, the contemporary modification of the building has distorted or eliminated features including the two side doors on the front, the floor coverings, and the throne base (Jwa-tap) that consisted the most significant part of the throne. Seonjeong-jeon originally had three doors that stood between each pair of columns on the front side, respectively. The courtiers accessed the building through the side doors, while the central door was exclusively designated for the king. However, the renovation in 1999 ignored the political context of the architectural form of the building and changed the side doors into windows, damaging the traditional structure inherited from the early Joseon Dynasty. Although the building currently has traditional wooden floor structure (Woomul-maru), it was originally covered with square brick tiles (Bang-jeon) before the Japanese occupation, following the customs of early Joseon Dynasty. The throne was placed to the north of the central door and consisted of the throne base and a decorative roof (Dang-ga). A canvas (Jang-ja), which featured the royal symbolic painting of Sun, Moon, and Five Peaks, was also installed between the two columns that connected the base and the roof. Nevertheless, only the columns and the blank canvas remain nowadays after the removal of the base.

태초의 인간은 자연으로부터 정신적ㆍ물질적 만족을 얻으려 하였다. 그러나 인간은 자연에서 그러한 만족을 얻지 못하자 문명을 형성하게 되었고, 거기서 인간만의 독특한 환경을 발전시키며 자연성과 대립하여 왔다. 이러한 대립의 과정에서 인류는 생태적 위기문제를 끌어안게 되었다. 문제를 해결하기 위한 대안으로 많은 분야에서 생태학적 패러다임에 관심을 갖기 시작했으며 사람이 살아가기 위한 필수적 공간디자인의 영역으로 관심이 집중되고 있는 실정이다. 이 가운데 한국의 전통건축은 한국의 자연과 풍토에 적합한 생태적 특성을 지녀왔다. 특히 한국의 전통건축을 생태학적 패러다임에서 논의해 볼 때 그것은 서양의 건축물처럼 독립된 개체적 구조물이 아니라 인간과 함께 자연 생태계의 일부로 함께 존재하는 전체적 화합물이라는 인식으로 주요 연구대상이 되어왔었다. 그 가운데 특히 한국 전통의 창문은 자연을 수용하고 받아들임에 있어 생태적 본질을 가장 잘 유지한 예의 하나로서 생태학적 공간디자인의 연구대상으로 매우 중요한 의의를 가지고 있지만 실제로 오늘날의 한국현대 건축의 관심에서 밀려나 있음은 지극히 안타까운 일이 아닐수 없다. 본고는 이러한 점에 초점을 맞추어 한국 고유의 전통인 창과 문을 새로운 공간디자인의 연구대상으로 현대화시켜 그 영역을 확대시키는데 목적을 두었다.
