The Korea South-East Power Co., Ltd.(KOSEP) held a design competition for Energy Theme Park at Yeong-Heung power plant in October, 2004. The site is located in 980-1 Oe-ri, Yeong-Heung myun, OngJin gun, Incheon City and has an area of $54,450m^2$. Design objectives of KOSEP were to make environmentally sustainable space, to build a symbolic and gathering place for community members and visitors, to make a tourist spot of Yeong-Heung Island linked with adjacent sight spots in OngJin gun, and to elevate an identity and status of the KOSEP by creating a landscape correspondent to the concept of the building design. The spatial concept of this project was developed by expressing a circular course of energy, named 'energy circle' and accounting for principles of energy generation. By interpreting 'energy circle' and principles of energy generation, and applying it to the site, the design met the various desires of the KOSEP. This design consists of seven theme spaces; the future energy plaza, the wind plaza, the light plaza, the thermal power plaza, a water strider dam, a ecological pond and the stratum plaza. These theme spaces are consecutively placed along the circular path which surrounds the public information building and to represent how power plants generate energy in each space and diverse design techniques and special effects are used.

수 세기에 걸쳐 대학이 성장함에 따라 이는 주변의 커뮤니티와 더욱 밀접한 관련을 지으며 발전하거나 변화하게 된다. 초기의 작은 도시는 19세기를 통해 산업화를 겪고 중심지로 발전하게 되며, 대부분의 도시들은 대학을 중심으로 산업과 연구의 기조를 형성하고 이는 문화적으로 다양한 인구의 밀집지를 이루는데 한 근간이 되어왔다. 대학을 중심으로 구성되어 있는 커뮤니티는 그 자체가 하나의 작은 도시구조의 모습을 띄며, 대학과 인근 지역은 협조, 혹은 마찰을 공유하며 성장하고 변화한다. 많은 미국의 대학들이 대학의 성장과 함께 필요한 건물과 시설을 확장하고 개발하면서, 이로 인해 빚어지는 교통량의 증대와 기존 오픈스페이스의 손실 등 성장관리에 귀추를 두고 기존 지역과의 융화를 꾀하며 발전을 추구하고 있다. 하버드 대학의 북쪽 캠퍼스 개발의 사례를 통해 지역개발의 한 단편으로서 캠퍼스 개발계획은 어떠한 의미가 있는지 살펴보고자 한다.

In 2004, the Incheon Urban Development Corporation held a design competition for the Song-Do apartment complex development. Several projects that won the prize in the recent design competitions were reviewed to look around the current design tendency, and current conditions of the site were surveyed. The authors tried to combine digital and environment-friendly factors, considering the site condition. Because the site is on reclaimed land and is located at the center of the information-technology industrial area, these two factors inform the main concept of this project. The site was divided into two different zones : the Ocean Zone and the Digital Zone. The 'community spaces'(community street, community plaza and so on) were designed for the various activities of the residents. The Patios, 'private' community spaces, included many facilities for play, appreciation, rest, exercise, refreshment and gathering. To avoid common landscape styles in the patios, simple and minimal forms were designed. The environmental sculptures were carefully planned, allocated and shaped with digital technology, based on the 'Present and Future of Song-Do'. The authors also tried to introduce environment-friendly factors, such as the green roof system, wall planting, and the water recycling system. This project is following the M.A. (Master Architect) process, and is still being modified to make the hi-tech and environment-friendly apartment complex.

Advancement toward aging society has presented the importance of house planning in consideration of the elderly, increasing the necessity of such planning. Therefore the importance of indoor design guideline for elderly houses has been stressed and the understanding of the aging in regard to this trend will create more mature spaces. In line with this trend the purpose of this study is to study the medical factors related with bathroom interior design guidelines of the existing elderly houses from the viewpoint of deteriorating physical functions due to aging process. In order to research the deterioration of physical functions due to aging literatures of medical and exercise physiology were used and concerning the existing bathroom design guidelines for the aged people, the guideline items of behavior facilitation, physiological maintenance and perceptual maintenance aspects out of Murtha & Lee's user benefit criteria(1976) related with physical functions were selected to research in relation with the knowledge about the deterioration phenomena of physical functions. Physical aging and deterioration aspects were classified from the viewpoint of musculoskeletal disorder, cardiovascular disorder, respiratory disorder, gastronomy disorder, urology disorder, somatosensory disorder, endocrine disorder, immune disorder, nervous disorder and skin diseases and these were utilized in interpreting total 100 items of bathroom design guideline. Because bathroom is the space where many physical movements are done, it had the closest relationship with the deterioration of musculoskeletal health in general and as bathroom is the space where people use water and feel the difference in temperature and moisture more than other spaces, deterioration of skin and somatosensory health had the next closest relationship. The result of this study revealed that regarding the deterioration of physical functions of the elderly people in aspect of their perceptibility as designers will design creatively and sincerely based on its relationship with nervous system in future, the result of this study will be used to develop better spatial designs efficiently to meet for the aging society.

Objectives: This study was conducted to prevent asphyxiation of firefighters during confined space rescue. The specific purpose was to identify the magnitude of the problem, identify the cause of the accidents, and suggest measures to ensure safety of confined space rescues. Methods: We collected data from National Fallen Firefighters Memorial, press releases, and other sources In order to identify the current situation of asphyxiation incidents among firefighters from 1945 to 2019. In addition, an incident investigation was conducted for each case, and the processes, causes, and control measures of the incidents were described as a narrative data entry. Results: Over the past 73 years, eight incidents involving firefighter in Korea have occurred. In these incidents, five firefighters were killed, and eight were injured. The confined spaces incidents occurred were water supply tanks, wastewater treatment tanks, pickling pits, septic tanks, and more. The causes were three cases of hydrogen sulfide poisoning, one of oxygen deficiency, one of carbon monoxide poisoning, and three unclassifiable asphyxiations. The people in need were all workers in various industries. Conclusions: The number of firefighters' deaths and injuries during rescues in confined spaces was severe and the risks have not been completely eliminated. By establishing and implementing a precise incident investigation system, according control measures should be initiatedin order to prevent a recurrence of the same type of disaster and reflected in the SOP. In particular, due to the high risk of occurrence at workplaces, cooperation between fire and rescue authority and relevant agencies such as the Ministry of Employment and Labor and the KOSHA should be strengthened.

This qualitative research was designed to explore the use of housing among Korean Chinese people in Harbin, China. Focusing on the use which based on the epistemology of housing adjustment, this was particularly designed to examine its cultural assimilation and acculturation on the way of life course, it employed the in-depth interview on the oral history of 5 interviewees in their 60s and 70s, individualized interviews were conducted from May 28 to 31 in 2010. Key findings were summarized as follows; 1. The free market reform in China resulted in privatization that allowed respondents to become homeowners, and the ownership was viewed as part of family asset centered upon a sense of solidarity. 2. Although homeowners in multi-story houses were responsible to decorate interior spaces, the common features in using interior spaces were found: entrance had no thresholds; kitchen was small, lack of storage cabinets, tile-flooring; washers were installed inside bathroom; and newly built apartment didn't have proper space to store Korean fermented foods. It was observed that housing adaptation outweighed housing adjustment. Those who used to live in Chinese houses with indoor-wearing-shoes or Russian houses with indoor-wearing-slippers were receptive to the use of dining table and bed, and the community heating system discouraged the use of individual electric water heater because of high electricity cost. 3. In daily life, eating habit wasn't much changed to the Chinese style, meals were shared, dish sterilizer was popular, and Kimchi fridge wasn't used. Because of the influence of the Chinese culture, such Korean traditions as ancestral rites and bedroom allocation tradition faded away, but traditional family values remained unchanged. In conclusion, Korean Chinese people experience normative housing deficits and adaptation selectively incurred. It's implied that residential design meets the needs resulting from the dual culture in terms of cultural assimilation and acculturation.

In order to increase the indoor air purification effect of plants, plants need to be placed on 5-10% of indoor spaces. To increase the density and utilization of plants in indoor spaces, studies on bio-wall, a vertical green wall system, have been recently conducted. The purpose of this study was to investigate the growth characteristics of 7 indoor plants introduced to the system and their rooting zones at different irrigation cycles. This study was conducted to investigate a proper irrigation cycle for the continuous maintenance of bio-wall systems. The conditions of their growth environment were maintained as follows: light intensity, 20-50 μmol·m^-2·s^-1 PPFD; and temperature, 20 - 25℃. For fertilization, Hyponex diluted with water at the ratio of 1:1,000 was supplied to plants. Irrigation was treated at intervals of 1, 3, 5, and 7 days for 1 hour at a time. As a result, there was no significant difference in the growth of plants between different irrigation cycles. Dieffenbachia 'Marianne' showed a significant decrease in the number of leaves at the irrigation cycle of 7 days. In addition, the chlorophyll content was relatively low at the irrigation cycle of 7 days. In terms of the color of leaves, a decrease in L value and b value and an increase in a value were observed, resulting in changes in brightness and color. Ardisia pusilla 'Variegata' showed a slightly higher photosynthetic activity and stomatal conductance when it was watered every day and once per 5 days, while Epipremnum aureum showed a relatively higher photosynthetic activity and stomatal conductance at the irrigation cycle of 3 days. In the case of root activity, it was found that the longer irrigation cycle, the higher root activity compared to daily irrigation. The development of roots of Peperomia clusiifolia was promoted by watering at long intervals. However, in the case of Aglaonema 'Siam-Aurora', the total number of roots decreased at the interval of 7 days. In conclusion, a proper irrigation cycle for the sustainable maintenance of vertical bio-wall systems seems to be 3 days.

Methods used for exploring marine resources and spaces include positioning a probe under water and then recalling it after a specified time. Hydro-acoustic Releasers are commonly used for positioning and retrieving of such exploration equipment. The most important factor in this kind of system is the reliability for recalling the instruments. The frequently used ultrasonic signal detection method can detect ultrasonic signals using a fixed comparator, but because of increased rates of errors due to outside interferences, information is repetitively acquired. This study presents an effective ultrasonic signal detection algorithm using the characteristics of a resonance and adaptive comparator Combined with the FSK+ASK modulator. As a result, approximately 8.8% of ultrasonic wave communication errors caused by background noise and transmission losses were reduced for effectively detecting ultrasonic waves. Furthermore, the resonance circuit's quality factor was enhanced (Q = 120 to 160). As such, the bias voltage of the transistor (Vb= 3.3 to 6.8V) was increased thereby enhancing the frequency's selectivity.
