Recently, many study of the Kigong, but that is in the point of the view in Taoism and Ki itself. So, it thought that the study in comparison Kigong(Taoism) to Oriental Medicine is insufficient. I thought much of that there are many description of the movement and the effect in the the body in the old book written Taoism, Doinbub(Physical and breathing exercise), and that there are many relation the circulation of the Ki to 12 Jung-kyung(12 regular meridians). Then I give a report of the result that the study is compared in Taoism with in Oriental Medicine. The results were as follows, 1. In the training of Doinbub, the effect is regulating muscle and skeleton, promote wi(constructive) system and ki(superficial) system, promote the ki and blood, strengthen the body resistance and dispel the invading pathogenic factors and preventive treatment. 2. In the training of Doinbub, the movements were much related to 12 regular Meridians and Muscles along the 12 meridians. 3. In the training of Doinbub, the effects were much related to 12 regular Meridians and Muscles along the 12 meridians. 4. It is possible that we set pathological syndrome to Doinbub(Physical and breathing exercise).

정서와 생리반응 (자율신경계 반응) 간의 관계에 관하여 성인을 대상으로 최근가지 많은 연구가 행해져 왔다. 본 연구에서는 동일한 실험참여자를 대상으로 일정 기간 동안 여러 회의 반복실험을 통해 정서(기쁨, 슬픔, 분노, 공포, 혐오)에 따른 자율신경계의 반응의 일관성과 정서별 자율신경계 반응 패턴을 규명하고자 하였다. 본 실험에 앞서 저서를 유발하기 우한 도구인 정서유발자극세트와 정서에 대한 심리반응을 평가하기 위한 정서평가척도가 제작되었다. 정서유발자극세트는 2-4분 정도의 각 정서 장면이 포함된 총 5개의 동영상 장면들이다. 예비실험을 통해 70% 이상의 적합성 및 효과성을 가진 4개의 세트를 추출하여 본 실험에 사용하였다. 본 실험은 남녀 대학생 12명을 대상으로 4회 반복해서 실시되었다. 실험참여자들은 각 정서 장면을 시청 후, 유발된 정서에 대한 심리적인 평가를 하였다. 측정한 자율신경계 생리반응 변수는 ECG, PPG, EDA, SKT이었다. 연구 결과, 심리반응에서 정서유발자극세트는 75% 이상의 적합성 및 효과성을 보였다. 생리반응(ECG, EDA) 분석 결과, 정서에 따른 자율신경계 반응은 회기별로 일관적이었으며, 각 정서별로 특정적인 생리반응 패턴을 가지는 것으로 나타났다.

The demand for building remodeling is increasing because of its reduced waste, cost, and duration compared to reconstruction. As the predecessor of new construction in a remodeling project, selective demolition significantly affects the cost and duration of the overall project. However, the standard estimating system (SES) in Korea provides only limited items for selective demolition in remodeling projects. Hence, for many items that are not on the SES list, one has to adopt a similar item from the SES or employ another rule that may not be standardized. Focusing on ceilings, flooring, and walls, this study analyzes problems in the similar-item application for those missing items through comparison among SES, RSMeans, and real project data. It has been found that: the numbers of items in SES are far lower than those of RSMeans and real project data: the similar-item application has serious shortages because of production rate variance: and the production rates in SES are lower than those of RSMeans. In addition, arranging laborers in a team for a job is difficult for some works because of the laborers-per-unit work system that SES applies. In order to overcome these problems, the number of work items should be expanded with more practical production rates, and a new standard structure, such as daily output per team, should be introduced.

As one of measures to improve the environment in an automobile, Malodor caused by the automobile air conditioner evaporator was evaluated and analyzed using lab-scale test bench. The odor was simulated with an evaporator test bench equipped with an airflow controller, air temperature and relative humidity controller. To simulate the same characteristics of odor used to occur from automobiles, one used automobile air conditioner evaporator associated with unpleasant odors was selected. The odor was evaluated by trained panels and sampled with aluminium polyester bags. Samples were analyzed by thermal desorption into a cryotrap and subsequent gas chromatographic separation, followed by simultaneous olfactometry, flame ionization detector and identified by mass spectrometry. Because compounds are concentrated before thermal desorption, such sample as odor from evaporator was able to detect trace compounds participating in odor. Compounds such as aromatic hydrocarbons, alcohols, aldehydes, and organic acids were identified. GC/FID/Olfactometry combined sensory method with instrumental analysis was very effective for odor evaluation method in an automobile air conditioner evaporator.

Korea has experienced a fast economic growth during the 70s and the 80s, In the 90s, increased interest for better lifestyle has led to policy assistances in the field of culture and arts. Throughout the 80s and the 90s, there had been multilateral efforts to improve the poor cultural environment. Under this background, starting from 1983, central and each local government started to establish culture & arts centers to clear overemphasis of cultural facilities in the capital city and promote regional characteristics. Most culture & arts centers that were built over 20 years ago are not only deteriorated but have limited usage. The reverberation time for most of these buildings are as short as around 1.00 second. Therefore, most culture & arts centers are bringing economic loss by limits of cultural activity. Based on this information, many culture & arts centers are in need to be remodeled into multipurpose performance halls, and it is crucial to review the original plan when being remodeled. Also, when construction new buildings, the lack of specific methods for designing multipurpose performance halls lead to various changes in design after review. Therefore, this study will utilize a checklist for remodeling and constructing multipurpose performance halls to efficiently design quality multipurpose performance halls. This method is expected to reduce economic loss and will be time-wise efficient.

The purpose of this study is to present an alternative method for resolving environmental issue associated with multiple dwelling architectural structures in the Green Building Certification System. It can be said that developers, in their desire to receive superior ratings from the Green Building Certification System, have strayed away from the original intent of resolving environmental problems through evaluation and certification. Therefore, to minimize this problem, I propose to conduct a comparative study on the apartment planning factors and the Green Building Certification System evaluation and certification factors.

Construction method of remodeling can be classified into two ways: remodeling of inhabited condition and vacancy remodeling. The advantage of remodeling of inhabited condition is continuous revenue income during construction period. Considering high vacancy rate of current commercial buildings, it also has benefit of low risk of losing good tenants and attracting new tenants. There are a number of ways to execute the remodeling depending on the setting of the work area and the tenants’ area. Therefore, this study calculate the earnings from leasing on construction methods of remodeling. Revenue calculation scheme is divided into three sections: not implemented construction area of construction, construction completion of the construction zone, after completion of a construction zone. And This study analyze the profitability of those remodeling methods and suggest a selection method of construction.
