  • Particle deposition in human lungs was investigated theoretically by using asymmetric five-lobe lung model. The volumes of each of the five lobes were different, thereby forming an asymmetric lung structure. The tidal volume and flow rate of each lobe were scaled according to lobar volume. The total and regional deposition with various breathing patterns were calculated by means of tracking volume segments and accounting for particle loss during inhalation and exhalation. The deposition fractions were obtained for each airway generation and lung lobe, and dominant deposition mechanisms were investigated for different size particles. Results show that the tidal volume and flow rate have a characteristic influence on particle deposition. The total deposition fraction increases with an increase in tidal volume for all particle sizes. However, flow rate has dichotomous effects: a higher flow rate results in a sharp increase in deposition for large size particles, but decreases deposition for small size particles. Deposition distribution within the lung shifts proximally with higher flow rate whereas deposition peak shifts to the deeper lung region with larger tidal volume. Deposition fraction in each lobe was proportional to its volume. Among the three main deposition mechanisms, diffusion was dominant for particles < 0.5 ${\mu}{\textrm}{m}$ whereas sedimentation and impaction were most influential for larger size particles. Impaction was particularly dominant for particles> 8 ${\mu}{\textrm}{m}$. The results may prove to be useful for estimating deposition dose of inhaled pollutant particles at various breathing conditions.

  • 1월의 clo 값은 대체로 삼지연 지역이 가장 높게 나타나고, 장전 일대의 동해안 지역이 가장 낮게 나타난다. 또한 해안 지역보다 내륙 지역이, 동해안보다 서해안이 clo 값이 높게 나타난다. 이는 지형적 영향과 기온과 풍속의 지역적 차이에 기인한다. 8월에도 삼지연, 해산 일대, 개마고원 등이 높게 나타나는데, 이는 지형적 영향으로 기온 저하와 풍속의 증가로 나타나는 현상이다. 특히 8월에는 삼지연을 중심으로 북동-남서 내륙지역으로 등치선이 만곡하고, 이 축을 중심으로 한 이외의 지역이 비교적 낮은 분포를 보인다. 이러한 원인으로는 위도, 지형 및 장마 이후의 고온 다습한 북태평양 기단의 영향과 강한 일사에 의한 지면 복사열의 방출에 있다고 사료된다.

  • According to the rapid change in the era of Korea, there have been significant changes in the buildings and facilities in the rural area of the country, and thus in the landscape of the agricultural and fishing villages due to the painting of colors that are not in harmony with the surrounding natural environment. Recently, the value recognition on the rural landscape has greatly changed and studies are actively performed on rural colors. To keep up with this trend this study is intended to propose coloring plan of Byutgari and Eumpo area for their entire landscape including the facilities to harmonize with their natural and cultural characteristics and surrounding environments. This plan was related to the establishment of the landscape planning of the region in Taean-gun, Chungcheongnam-do, based on the already prepared rural environmental coloring guideline. This study has its significance in that it provided a coloring process that can be applied to the targeted are as well as other area, continuing the context of the precedent studies. It is greatly expected that the regional characteristics will be strengthened owing to the establishment of coloring guidelines.

  • The study background is that Mo-Jung happens as the produce of the agricultural society but it is not easy to find it beside Ho-nam area. Because of this, it results construction has. The study progress is to understand the happening time, and regional cause the Mo-Jung construction has. The study progress is to understand the happening time of Mo-Jung, constructional meaning, and the meaning of Mo-Jung with the investigation method of literature consideration of the village society, data of the existing study, survey investigation, interview, and question through the process of analyzing the characteristics of differentiation of the village and Dure organization. 1. Mo-Jung construction has the meaning of vernacular construction reflecting the meaning of village community intensively as an element comprising the village, and the territory of Mo-Jung space is revealed as the male space. 2. The economic wealth of the village community and the image reflecting the community sense are stood out. 3. It is the reason why Mo-Jung construction is limited to Ho-nam area and is explained as the life style difference each village community has, the regional characteristic difference Dae-dong play of Yong.Ho-nam areas have, etc. so to speak. 4. It is estimated that the happening time of Mo-Jung is after the 18th century when the agricultural As my suggestion, Mo-Jung construction is the construction phenomenon reflecting the phenomenon of social change directly and it is to suggest the possibility of approaching the regional housing construction as the life style difference the life community of each area has is reflected. production quantity was increased and Dure organization was activated.

  • In some port construction, a case of reclamation with dredged soil for land use can be found. Even though this is not a new technology, there are some problems on the test method and analysis. The design parameters are still remained to be solved to get accurate prediction. Sedimentation of particle and self-weight consolidation are the most important design parameters in reclamation by dredged soils. The design parameters are influenced by properties of the physical and sedimentation of dredged soils. This influencing factors can be determined depend on the history of long term sedimentation and particle characteristics. Thus, properties of the sedimentation and consolidation are varies depend on the regional geologic formation. In this paper, three different sites with different regional soil properties will be compared in design parameters of sedimentation and self-weight consolidation.

  • San-ja is one of the main members consisting of the roof of traditional wooden buildings in Korea. In this study, the regional characteristics of the materials used in San-ja and changes of the materials over time were examined. To this end, 123 documents on the repair of wooden architectural heritage recorded since the 1950s were reviewed. It was found that there was a difference in the San-ja material by region because of the diversity in the conditions of material supply. For instance, bamboo was the most frequently used material in Jeollanam-do province because it was readily available. However, with the development of transportation and vehicle, the regional characteristics have disappeared. As a result, the material has been unified with bamboo now. This is because bamboo is specified as a representative material in the specification or the convenience of construction is prioritized. In addition, the social and economic conditions at the time of repair had an influence on the selection of the San-ja materials.

  • A FCM with locational price and regional information between locations are proposed in this paper. Any point in a networked system has its own values indicating the physical characteristics of that networked system and regional information at the same time. The similarity measure used for FCM in this paper is defined through the system-wide characteristic values at each point. To avoid the grouping of geometrically distant locations with similar measures, the locational information are properly considered and incorporated in the proposed similarity measure. We have verified that the proposed measure has produced proper classification of a networked system, followed by an example of a networked electricity system.

  • A church architecture which has an important meaning as a place which is for worship God, relationship, education, evangelism, service and formative meaning that express as a specific form. It has been changed by age or changes of theology, also its structure and form has been changed so as to change of a rutual. the church architecture that has been authorized as a architecture which is a representation of the age does not represent the age and it has weaknesses for expression of unique identification church has. Also, because it is lacking thoughts about regional viewpoint, it loses the characteristic of regional "landmark" like the past. In addition, a place of worship has been changed materiality of space like auditorium or seats so as to change of consciousness of worship, and it is exposed problems of expression of identification. Therefore the church architecture of twenty first centry needs to holy and be able to deliver their new standards and needs that fit original purpose of church for users.
