LH has been using ultra high strength reinforcing bars (SD500 and SD600), since 2011. Such a change requires an adjustment of the old extra rates of bar splice to reflect use of ultra high strength reinforcing bars, as these rates had been set based on SD400 bars. It is particularly difficult to calculate precisely rebar lap-splice locations for large areas, such as those in apartment buildings. This research aims to adjust the extra rates of bar splice to reflect a reasonable rate; the rebar lap-splice length is not an exact estimation, but instead, an extra rates of bar splice is set and the rebar lap-splice length is increased by 2% (D 10) - 7% (025) depending on the bar size. The subjects of this study are LH apartments undergoing frame construction. We studied the quantity estimations from the design drawings, and analyzed the settlement quantities of construction field. The results of the study revealed that, when each of the quantities are analyzed, consider adjusting the extra rates of bar splice of some rebar to 1% - 3.5%. This was caused by an overuse of reinforcing bars in onsite construction and the use of supporting bars that have not been reflected in the documents, among other reasons. Based on the results of our study, an improvement plan for the current extra rates of bar splice seems to be necessary, cutting or raising the rate depending on the analysis of the data. Through this study, we expect to contribute to the calculation of reasonable construction costs, improvements in the quality of rebar work, and improvements in the capacity of design techniques for apartment buildings.

An intensive observing period (IOP) of heatwaves in the urban region of Seoul in the summer of 2023 was carried out to understand the changes in air temperature and road temperature induced by environmental conditions. The temperature observed at eight points with different urban environmental conditions was compared with the temperature by the KMA/AWS to analyze the characteristics of change in air temperature by height and the change in road temperature according to environmental conditions and road sprinkler. The comparison of the average temperature observed in different urban environmental conditions with the temperature observed at KMA/AWS showed that the air temperature in asphalt and open space sites was 0.7 to 2.3℃ higher and that the one in bus stops was 0.9 to 2.3℃ higher. In terms of temperature deviations depending on residential type, the temperature in highly populated areas was about 0.1 to 0.8℃ higher than that of apartment complexes. In addition, regardless of the size of a park, the temperature in the park was lower than the temperature in dense housing areas and apartment complexes. In asphalt and residential areas, the road temperature was higher than the temperature at a height of 150 cm, Conversely, road temperature was lower than air temperature in a shaded shelter and large park. In addition, after spraying a surface road, the road temperature immediately dropped by about 3 to 4℃; however, after about 20 minutes, it rose again to the previous road temperature. This change in road temperature appeared only for the temperature of 30 cm height.

As the standard of living has raised and the local self-governing body has enforced, cultural facilities have been increased in local areas. These cultural facilities should be designed to consider various users. However, most facilities were designed to focus on size or visual expressions. Therefore, this study was intended to evaluate common spaces of two cultural centers in local area from the universal design point of view. Two cultural centers located in large apartment complex were selected. The evaluating tool consisted of 46 elements related to universal design. The common space were pathway to entrance, parking lot, entrance, all over building, corridor, and restroom. Each 100 users of these two cultural centers evaluated them using by 5-point Likert scale. The results were as follows; The users rated them positively, but not highly. This means that some improvement were needed. Generally, the consideration for upgrading the quality of design such as material, pattern and color needed, and for various users including wheelchair users and seniors were needed. Also, when considering the users' behavior pattern and purposes, installing canopy over entrance, and providing seating places at corridor or pathway were needed.

This study attempts to explore the organization of domestic space in Belgium and then to compare them with those found in Korea. Data were collected by questionnaires mailed to 110 staff members, both academic an dadministrative, working at Vrije Universiteit Brussel in Belgium.The major findings of the study can be summarized as fllows: First, the most common pattern of Belgian LDK(living-room dining-room and kichen) layout is the LD type, which separates K from L and D by wall or door while linking L and D to each other. On the other hand, a large portions of Korean LDK layout is the DK type , which seperates L from D and H, but D and K are interconnected. As expected, the bigger the size of floor space, the more likely L-D-K type is to be, which places L, D, and f, separate each other. And the smaller the sire the more probable the DK type and/or the one room type would be, where L, D and K are merged into one room. Second, the enterance of domestic space in Belgium is normally found adjacent to public space. The Belgian entrance often forms a space independent from other parts of the house, or a space that leads directly to garage. These two patterns are rarely found in Korea. Third, Belgians tend to locate Kichen in the front of the house when they design apartment units, Whereas it is not the case in Korea where it is located in the rear.

본 연구는 부산시의 주택순환과정을 살펴보기 위해 가구의 생애주기에 따른 주거이동 특성을 분석하였는데, 설문조사는 부산시 거주 만 40세 이상의 성인들을 대상으로 결혼 이후 현재까지의 주거이동에 대한 주거경력을 조사하였다. 통계자료 분석의 결과와 설문조사 결과는 모든 항목에서 유사한 결과를 보였는데 이를 정리하면 다음과 같다. 설문대상자들이 현재 거주하고 있는 주택을 살펴보면, 주택유형은 아파트가 절대적으로 높은 비율을 차지하고 있으며, 주택의 점유형태는 자가소유이며, 주택규모는 30평형대, 거주기간은 6년 이상 10년 미만이다. 주택자금마련 방법은 저축과 은행대출이 대다수를 차지하고 있는데, 현재 가구의 소득만으로는 자가소유의 희망주택을 마련하는 것이 불가능함에도 불구하고 주택금융을 활용하여 내집마련을 하는 주거문화는 임대료를 지불하고 임차소유를 하는 외국과는 다소 다른 우리의 주거문화이다. 그러나 주거만족도의 측면에서 주거이동은 주택규모를 확장시키고 점유형태를 변화시켰기 때문에 주거이동으로 인해 대부분의 가구가 주거의 질이 향상되었다고 인식하고 있으며, 현재의 주거에 대해 매우 높은 만족감을 보인다.

This study aims to analyze the cases of storage space outside housing unit and propose the activation plan. The issue of storage in residential complex has continued to be reported. This is more salient due to the recent preference trend for small houses, the constant increase of living goods and the limitation of the available space inside housing unit. Although more apartment houses are trying to have individual storage in the exterior space to address these issues, there is still a paucity of the related studies and more studies are required. In this study, we conducted on-site investigation and user interview of each case to propose active usage of the storage space outside housing unit. Result of this study shows that the most crucial factor to improve is 'accessibility' in order to activate the storage space. Storage room should be located close to each household or the individual parking space. The second factor is the size and the structure of the storage room. The sufficient space for keeping and taking large objects out are required. The front of the storage room should have a clogged structure to insure privacy. The third is the provision of suitable support programs such as the system that occupants can check remotely what items are in their storage rooms, garage sale, laundry service, auto cleaning system and rental program. Those programs are required for efficient management and activation of space. Another requirement is to improve environmental factors which include maintenance of optimal temperature and humidity, automatic ventilation system, control of individual lights, and security enhancement. Based on the results of the survey, we provide basic data which can be used for practical space planning to activate exterior storage space of the housing unit. Further surveys are required to develop this study by obtaining more data for generalization.

Many of penthouse apartments began to be built and distributed in Korea from the 2000s. However, we have a transformed definition from the international concept of penthouse. It seems that the penthouse apartments in Korea have a confined definition as a luxury and privileged house-we often find it out from advertisements of newly built apartments. In this thesis, therefore, it needs to make a clear and substantial definition of penthouse. And on the base of this definition, this study is intended to analyze planes of penthouse apartments which are distributed recently. It is in order to find out positive aspects of penthouse apartments and to make practical application of this analysis. The process of this study for plane-planning is as follows. Firstly, it is investigated and analyzed that external factors that have an effect on plane-planning such as locations and types of penthouse apartments. Secondly, an interior of penthouse apartments are divided into a private, public and outward area. And properties of each area through this research show the way of division and arrangement of plane. Thirdly, methods of connection between spaces is analyzed on the base of results of research for the way of partition. Finally, specific characters of penthouse apartments planning is derived from synthesis of research. In conclusion, analysis of plane-planning of penthouse apartments is summarized as follows. The majority of penthouse apartments is arranged to small portions of households and on higher stories in apartment which is situated around Han River or public parks. These external factors influence the plane-planning in both the interior and exterior way. For the exterior planning in space, it becomes important to design bays as many as possible in contact with outside in order to satisfy demands for fine prospects. It is also important to plan extra places naturally such as a terrace in order to provide virtual grounding. In the interior planning, a large size of interior induces to develop space for linking between each area, such as corridors or extra rooms. This makes it possible that the private area is linked to each other, at the same time it has its own distinctiveness according to its usage.

본 연구는 심각해지는 토지문제를 해결하기 위해 최근에 시행되고 있는 여러가지 토지제도들이 효과적으로 운용되도록 지가를 정확히 산정하고자 하는 움직임에 대한 기초 연구로서, 다른 토지이용에 비해 월등 높은 지가를 보이고 중은 범위에서도 그 변동폭이 큰 상업지를 택하여, 상업지지가의 지역적 차이가 왜 발생하는지 알아보고자 하였다. $1989{\sim}1996$ 동안의 상업지역의 확산은 시 외곽에 빠르게 조성되고 있는 고밀도 아파트 단지를 배후지로 하여 주요 간선도로변을 따라 활발하게 이루어지고 있는 반면, 도심부는 영세한 부지규모 및 노후화한 건물들로 말미암아 급변하고 있는 상업환경의 변화에 능동적으로 대응하지 못하므로서 지가하락 현상을 보이고 있다. 상업지지가와 관련이 있으리라고 예상되는 6개 변수를 이용하여 중다희귀분석을 적용한 결과 보행자 통행량과 도심으로부터의 거리 등 두 변수가 상업지지가 변화량의 65% 정도를 설명해 주었다. 설명되지 않은 35%의 해명을 위해 잔차분석을 행한 결과 도심부의 과소예측, 시 외곽의 과대 예측을 읽을 수 있었는데 이는 광주시의 단핵구조적 특성의 반영일 뿐만 아니라 이 모델이 갖고 있는 한계이다.
