The first case of the Central Environmental Dispute Mediation Committee, which recently decided to repay the builder for damaging the solar power plant due to the obstruction of the sunshine of new buildings, came out. Even if the Respondent complies with the provisions of the Building Act, the decision of the Complainant can be considered to have been made in light of the fact that the applicant's power plant has suffered from sunlight damage. However, since the extent of the damage may differ depending on the weather, the decision is reserved, and there is room for additional disputes on a regular basis because the loss of power generation to be continuously generated is not reflected in the future. Therefore, in this study, we try to find the direction of dispute adjustment by summarizing the issues related to the generation of power generation due to the influence of shading through the analysis of the case of dispute related to sunlight related to the PV system.

The main goal of higher education institutions is to present a high level of quality education to its students. This study uses data mining techniques to extract educational data from cumulative databases and used them to make the right decisions. This paper also aims to find the factors affecting students' academic performance in Majmaah University, KSA, during 2010 - 2017 period. The study utilized a sample of 6,158 students enrolled from two colleges, males and females. The results showed a high percentage of stumbling and dismissed between graduate and regular students where more than 62.5% failed to follow the plan. Only 2% of students scored distinction during their study of all graduated since their grade point average, secondary level, was statistically significant, where p<0.05. Dismissed percentage was higher among males. These results promoted some recommendations in which decision-makers could take them in considerations for better improvement of academic achievements: including of specialized programs to follow-up in regards to stumbling and failure. Utilization of different communication tools are needed to activate academic advisory for dismiss and dropout evaluation.

As the number of aging bridges increases, more studies are being conducted on developing effective and reliable methods for the assessment and maintenance of bridges. With the advancement in new sensing systems and data learning techniques through AI technology, there is growing interests in how to evaluate bridges using these advanced techniques. This paper presents a CNN(Convolution Neural Network) deep learning based technique for evaluating the damage existence and for estimating the damage location in PSC bridges using static strain data. Simulation studies were conducted to investigate the proposed method with error analysis. Damage was simulated as the reduction in the stiffness of a finite element. A data learning model was constructed by applying the CNN technique as a type of deep learning. The damage status and its location were estimated using data set built through simulation. It was assumed that the strain gauges were installed in a regular interval under the PSC bridge girders. In order to increase the accuracy in evaluating damage, the squared error between the intact and measured strains are computed and applied for training the data model. Considering the damage occurring near the supports, the results of error analysis were compared according to whether strain data near the supports were included.

Jeju Special Self-Governing Province has implemented a self-governing environmental impact assessment system (Jeju-EIAS) in recognition of its autonomy. In this study, the institutional features of Jeju-EIAS were examined by analyzing the development projects whose consultation under Jeju-EIAS were completed from 1994 to 2019. The consultation procedure of Jeju-EIAS, such as the actual operation of Review Committee for Environmental Impact Assessment (EIA), the consent of the provincial council, and the regular follow-up activities for the implementation of EIA consultations, has been implemented differently from those of other metropolitan cities and provinces. Under Jeju-EIAS, types of development projects subject to consultation on EIA also take into account local conditions, and include the construction of aquarium basin and building. In addition, provisions concerning the scale of development projects is strengthened above the Korean Environmental Impact Assessment Act (EIA Act).

The software development life cycle (SDLC) is a procedure used to develop a software system that meets both the customer's needs and real-world requirements. The first phase of the SDLC involves creating a conceptual model that represents the involved domain in reality. In requirements engineering, building such a model is considered a bridge to the design and construction phases. However, this type of model can also serve as a basic model for identifying business processes and how these processes are interconnected to achieve the final result. This paper focuses on process modeling in organizations, per se, beyond its application in the SDLC when an organization needs further documentation to meet its growth needs and address regular changes over time. The resultant process documentation is created alongside the daily operations of the business process. The model provides visualization and documentation of processes to assist in defining work patterns, avoiding redundancy, or even designing new processes. In this paper, a proposed diagrammatic representation models each process using one diagram comprising five actions and two types of relations to build three levels of depiction. These levels consist of a static description, events, and the behavior of the modeled process. The viability of a thinging machine is demonstrated by re-modeling some examples from the literature.

The author recommends the creation of a nationwide career guidance program at the national level through the establishment of a long-term cohort, involving collaboration among medical schools nationwide. This cohort would be constructed for the purpose of analyzing correlations from admission to medical school to post-graduate education, facilitating the development of a career guidance program. This will aid in career development through students' self-analysis and competency building. Each medical school should operate a systematic career guidance program. Career guidance for post-graduate major selection should be included in the regular curriculum. Schools are advised to operate student counseling rooms for various career guidance services. For example, medical schools can operate 1:1 career counseling, academic counseling, career guidance surveys, psychological tests, and counseling. It is advisable to establish a mentor-professor system, connect mentor professors, and build a network of experts related to majors to provide immediate support according to students' needs. Professional mentor training should be provided to mentor professors. To provide opportunities for students to experience their career paths in advance, early clinical exposure, long-term integrated clinical practice, community-based clinical practice, participation in student research programs, career fairs, and student internship programs are recommended. In South Korea, it is necessary to systematically operate the internship system and make improvements to facilitate optical career choices. Additionally, considering the significant influence of social factors on students' career choices in South Korea, efforts should be made to identify and address the issues related to these social factors.

최근 들어 옥외광고물에 대한 행정적 규제나 방침이 적용되고 있고 광고물 자체의 디자인이 향상되고 있으나 건축물 유형과 관련한 현실적인 옥외광고물의 상관성 연구는 부족한 실정이다. 그러므로 양자간의 정량적 상관성 분석을 통하여 도심 가로변 복합상업건축물의 디자인 시 옥외광고물의 패턴과 량을 미리 고려하여 입면을 개선하는 방법을 제시해보고자 한다. 매스계획 시에는 첫째, 전면공지형이 바로인접형 보다 옥외광고물 밀도를 낮추는 수단이 된다. 둘째, 전면적이 유사하면 높이차이가 있어도 광고물 수에는 변화가 없는 것으로 밝혀져 4층 이상 건물의 가로형광고물도 허가 시 총량을 제어하는 방안이 도입될 필요성이 제기되었다. 셋째, 동일레벨보다 상승진입형으로 가로와 접하는 건물 옥외광고물의 밀도가 더 낮으므로 입면계획 시 이를 반영하되 가로특성별로 입면레벨 제어가 필요하다. 넷째, 스팬드럴이나 베란다 세장비를 옥외광고물 부착이 어려운 형태로 줄이고 매스 측면모서리에 돌출세로형광고물의 위치를 미리 배려하는 것이 유리하다. 다섯째, 중층부에는 세로형 돌출옥외광고물을, 중 고충부는 광고물이 작은 단위로 분산되지 않도록 큰 면적을 할애해야한다. 입면계획 시에는 첫째, 수직형보다 수평형 벽면과 횡연창이 많으므로 건물의 스팬드럴 위치와 폭을 일정하게 유지하면 이후 정렬된 광고물 설치를 기대할 수 있다. 둘째, 불규칙형 벽면형태가 단일주조형에 비해 오히려 광고물 총량 제어에 유리하다. 셋째, 횡연창이 광고물 총량을 가장 제어하기 힘들며, 복합창의 경우 횡연+종연창 복합형의 광고물이 격자+횡연창이나 격자+전면창에 비해 상대적으로 많으므로 이를 입면계획에 반영해야 한다. 넷째, 전면창복합형>격자창복합형>횡연창 복합형 순으로 광고물 제어에 유리하다. 그러므로 복합상업건축물 입면계획 시 일방적인 수평요소의 반복은 지양할 필요가 있다. 모서리계획 시에는, 첫째, 2개 이상의 가로와 접하는 건물의 경우 모서리부 광고 효과가 지배적이며 대부분 곡선돌출형이 사용되고 있었다. 그러므로 모서리 저층부를 필로티로 계획하여 보행흐름을 원활하게 하고 대신 입면을 투명하게 하여 간접광고(내부전시) 효과를 유도하는 것이 좋다. 특히 원형모서리는 건물 특화 성격이 강하므로 불가피할 경우 소형 액센트 광고 위치를 미리 벽면으로 할애하는 것이 경관 및 입면계획에 유리한 것으로 분석되었다.

본 연구는 자원의 재활용 측면에서 적용한 폐타이어 분말을 혼입한 모르타르에 난연제를 첨가하여 그 난연특성을 알아보고자 한다. 폐타이어 분말의 혼입으로 단열성능 향상은 이미 검증이 되었으나, 단열성과 결합력의 상반된 재료 특성으로 인해 화재에는 취약한 바. 이에 난연제를 첨가하여 인명안전에 만전을 기하고자 한다. 폐타이어 분말을 혼입한 모르타르의 난연제를 첨가하여 첨가 비율에 따른 그 특성을 알아보고자 한다. 화재 초기의 특성을 알 수 있는 재료의 가연성 여부를 실제 화재와 유사한 복사열에 의해 시험하고자 하였으며. 실험방법은 한국건자재 시험연구원에 의뢰하여 ISO 5657 절차에 의한 재료의 착화시간, 불꽃 발생여부, 시험체의 형태변화 등을 고찰하고자 한다. 폐타이어 분말이 혼입된 모르타르와 난연제(무기계)의 배합비율은 폐타이어 분말의 0%, 30%, 60%, 90% 비율로 수산화알루미늄을 첨가하며 조연제인 삼산화안티몬은 난연제의 10%를 첨가한다. 시험체를 수평설치하여 일정한 복사열($1{\sim}5W/cm^2$)을 시험체 상부표면에 노출시키면 열이 시험체 표면에서 내부로 전도되어 온도가 상승한다. 온도가 충분히 높다면 시험체는 열분해하면서 가연성가스를 발생시킨다. 이 때 점화원인 점화기구의 작은 불꽃은 시험체 중앙 위의 10mm 지점에 규칙적인 간격으로 접염하였을때의 재료의 지속적인 표면 착화특성(착화시간) 평가한다. 난연제 미첨가시에도 착화가 일어나지 않아 폐타이어분말이 혼입된 모르타르의 가연성은 적은 것으로 볼 수 있으며, 화재실내에 존재하는 가연물의 양을 평가하는 화재하중에 이를 반영할 수 있다. 폐타이어 분말에 무기계 난연제를 첨가함에 따라 흡열효과에 의해 불꽃은 발생하지 아니하고 폐타이어 분말입자의 분해속도도 지연되었음을 확인할 수 있다. 복사열로 인해 난연제인 수산화알루미늄이 열분해하여 모르타르내 수증기 분압이 증가하여, 폐타이어 분말의 불꽃이나 연소형태는 보이지 않았다.

최근 건설공사에 이슈가 되고 있는 건축정보모델링(BIM)은 건설경기 둔화와 수주물량 감소에 따라 위기위식이 팽배한 건설산업의 새로운 돌파구로 주목받고 있다. 이미 건축분야는 국내외적으로 BIM을 도입하기 위해 관련연구가 활발히 진행되고 있다. 하지만 토목공사의 경우 건축공사와 달리 작업체계가 비반복적, 수평적, 비정형적이며, 프로젝트 수행 범위가 넓어 발생하는 정보의 양도 방대하여 건설사나 설계사에서는 BIM 구축을 위한 초기 투자비용의 부담과 투자대비 효과에 대한 의문과 부담을 갖고 있다. 이에, 국내 토목분야에 BIM을 적용하기 위해 토목설계 전문가들을 대상으로 BIM 기술수준을 파악하고 과거대비 현재 토목분야의 BIM에 대한 인식변화 분석을 통해 토목분야 BIM 활성화 저해요인을 파악하고 이를 해결할 수 있는 방안을 제시하였다. 도출된 활성화 방안은 가이드 개발, 제도 개발, 납품성과 검증, 국제표준 상정 등 4가지 분야로 구성된다. 연구결과는 토목분야 BIM 적용을 위한 표준과 납품 성과품의 검수 및 검증체계 개발 연구과제의 연구방향 설정을 위한 기초자료로 활용될 수 있을 것이다.
