The objective of this paper is to investigate problems associated with Rural Housing Standard Plans for the Elderly based on the current status of 12 houses belonging to elderly people (60's and over) living in rural areas and engaged in farming activities, and to suggest improvements. The methods employed were a field survey with interviews and literature review. The results are as follows. First, the Plans were deemed inappropriate to prevent the possible accidents in entrance area such as slippiness and falls because the eaves are not long enough. Second, the area of foyer and the volume of foyer storage in the Plans are not enough to accommodate the subject's behaviors and their rural life. Third, rather than using the sink, many subjects preferred to wash simply in the shower while sitting, so the planning of a bathroom can't meet the subject's needs and behaviors. Fourth, the subjects prefer L + DK to LDK but the Plans were designed in the manner of LDK only. Fifth, the subjects have needs for bathrooms belong to the master bedrooms, but only one case of Plans satisfied their needs. Six, bedrooms with the exception of the master bedroom are used as storage in order to make up for a lack of storage space, but many storage space such as dressing rooms and pantries was not taken into consideration in the Plans. Lastly, the planning of storehouses does not meet the subjects' using behaviors for storehouses and the level of desirable capacity of goods.

본 논문에서는 FDD 방식 LTE 서비스의 핵심 대역으로 중요성이 부각되고 있는 1.8 GHz(3GPP 밴드 3)의 효율적 이용을 위한 주파수 재배치 방안을 제시하고, 이를 효과적으로 추진하는 데 있어 문제가 될 수 있는 전파 법령상의 조항 및 이를 개선하기 위한 방안을 논한다. 본 논문에서는 용도 간에 혼합적으로 이용되고 있는 1.8 GHz 대역을 유럽 국가들과 유사한 형태로 전체 대역을 이동 통신 용도로 특히 LTE 용도로 효과적으로 활용하기 위해서는 주파수의 인접성 요구 조건이 만족되도록 재배치시켜 광대역화 하는 것이 중요하며, 이를 가능하게 하는 방안으로 2가지의 대안을 예시적인 설명과 함께 제시한다. 그리고 각 대안을 정책사항으로 추진할 경우에 논란이 예상되는 전파 법령상의 여러 조항들을 식별하고, 이를 해소하기 위한 방안에 관하여 논한다.

Korean academic libraries are facing serious space shortage problems due to an inability to accommodate for the rapidly increasing number of printed materials. Despite the current situation, Korean academic libraries have largely focused on impractical applications of the new library paradigm, using technology or management programs to improve the quality of research and learning environments of the university. However, such improvements would be fruitless without first resolving the space shortage crisis. In order to make realistic improvements to the quality of academic libraries, this study used questionnaires to employ the opinions of librarians currently practicing at such Korean libraries. Survey questionnaires about types and causes of space shortage problems, library facility expansion plans, expected effects of expansion, frequency of and reasons for furniture relocation, and tight spaces needing improvement were distributed to selected 4-year college librarians through Google Drive. Analysis of survey responses indicated that library space shortage was largely responsible for the hindrance of research and learning environments. Furthermore, it reflected the urgency to secure book storage space.

The Qualitative improvements of outdoor spaces are unsatisfactory in comparison with that of indoor environment in existing apartments. Lately construction companies are differentiating the outdoor spaces of apartment complexes to meet needs of residents. However, high-rise buildings inherently have limitations on providing exposure to the outdoor settings and inappropriate lightings could have serious impacts on physical and psychological health of residents. Therefore, the purpose of this study is to provide useful information for the luminous environment of outdoor spaces through the analysis of current apartment complexes' lighting plans. Outdoor space of branded apartment complexes in Seoul, built after the year 2003, were researched. Through site visits, illumination level and lighting plans were investigated classified into entry area, passage area, plaza, rest area, exercise area, and play area. With the result, illumination level of apartment complexes researched was lower than KS illumination standard in all areas and the lighting plans were mostly shown in different condition of first intended lighting plan because of insufficiency of maintenance in lighting system. Therefore, it is need to provide better luminous environment to make outdoor space more lively and energetic at the night time.

Accelerated partial breast irradiation (APBI) is a new treatment delivery technique that decreases overall treatment time by using higher fractional doses than conventional fractionation. Here, a quantitative analysis study of CyberKnife-based APBI was performed on 10 patients with left-sided breast cancer who had already finished conventional treatment at the Inha University Hospital. Dosimetric parameters for four kinds of treatment plans (3D-CRT, IMRT, VMAT, and CyberKnife) were analyzed and compared with constraints in the NSABP B39/RTOG 0413 protocol and a published CyberKnife-based APBI study. For the 10 patients recruited in this study, all the dosimetric parameters, including target coverage and doses to normal structures, met the NSABP B39/RTOG 0413 protocol. Compared with other treatment plans, a more conformal dose to the target and better dose sparing of critical structures were observed in CyberKnife plans. Accelerated partial breast irradiation via CyberKnife is a suitable treatment delivery technique for partial breast irradiation and offers improvements over external beam APBI techniques.

As the use of advanced quality materials in constructions has been increasing since 1980 with the improvements in the quality of life and economic scale, there has been drastic increase in constructions using stones for the internal and external construction materials. However, the reality is where many problems rise due to improper construction and management of uncertified stones which shorten the expiry date of the stones and act as the factor causing defects in buildings. Such defects not only bring economic losses but also influence consumer choice and act as risk factors to demand expansion of stone market. Therefore, the object of this study lies on proposing plans to prevent personal and economical losses due to repetitive defects by deriving the types of defects generated by process in stone constructions and identify the causes. Also, proposing construction process management plans as the measure for defect prevention, analyzing problems of stone constructions followed by the whole proves of design, construction and maintenance of stones, and solving such problems through appropriate participation of professional consultants depending on situations.

This research investigated 162 residential unit plans which were located in Seoul and Gyonggi Province ranging from 58 to $118m^2$ unit net area recently. Through the investigation of unit plans, a matrix was developed based on the 5 criteria for space composition types. 5 criteria are building stock types, W/D ratio of units, unit net area, number of bay to the main orientation, and openness types. After review the matrix, 10 typical unit types were selected. At the same time, quantitative evaluation indicators were developed based on the 4 criteria such as efficiency, openness, flexibility, environmental sustainability. On each criterion, 3 indicators were developed, and measured on 162 residential unit plans. Firstly, correlation analysis were pursued on 5 criteria for space composition types and 12 quantitative evaluation indicators, and reviewed on each other. Finally, quantitative evaluation indicators of 10 typical unit types were displayed on radar charts in order to show the integrated evaluation on 4 criteria such as efficiency, openness, flexibility, environmental sustainability. From the reviews and radar chart analyses, advantages, disadvantages, and improvements on each typical unit type were presented as research results.

기존 철도교량은 과거로부터 각종 개량이 시행되고 있고 사회적·기술적인 요구 등으로 새로운 개량계획이 수립되고 있지만 해당 개소가 많고 소요비용이 막대하여 한정된 예산에서는 무엇보다도 효율적인 시행계획이 필요하다. 각종 개량계획을 체계화시키기 위해서는 시스템 차원의 문제로 간주하여 요소들을 정의하고 기술해야 하며 중요도, 상관관계 등은 평가기법을 이용하여 종합화가 이루어져야 한다. 이에 본 연구는 의사결정의 목적에 부합하도록 다양한 평가기준 하에서 대안들을 상호 평가하는 최적화 선정과정을 거쳐 각종 개량계획의 우선순위를 결정하고자 하였다. 체계화 설정과정과 선호도 평가를 위해 AHP 분석기법이 적용되었고 보다 적정한 개량계획의 요소를 도출 선정하고자 수행공학의 절차과정이 활용되었다.
