Support vector machine (SVM) active learning plays a key role in the interactive content-based image retrieval (CBIR) community. However, the regular SVM active learning is challenged by what we call "the small example problem" and "the asymmetric distribution problem." This paper attempts to integrate the merits of semi-supervised learning, ensemble learning, and active learning into the interactive CBIR. Concretely, unlabeled images are exploited to facilitate boosting by helping augment the diversity among base SVM classifiers, and then the learned ensemble model is used to identify the most informative images for active learning. In particular, a bias-weighting mechanism is developed to guide the ensemble model to pay more attention on positive images than negative images. Experiments on 5000 Corel images show that the proposed method yields better retrieval performance by an amount of 0.16 in mean average precision compared to regular SVM active learning, which is more effective than some existing improved variants of SVM active learning.

It is very important to pay careful attention to construction of earthwork/tunnel transition zone for railway. The transition zone of the railway is the section which roadbed stiffness is suddenly varied. Differences in stiffness have dynamic effects and these increase the forces in the track and the extent of deformation. In this study, performance of transition zone was investigated through the field tests. The wheel loads and sleeper settlement were measured after installing field testing sections.

This study seeks to examine how the West, particularly United States (US), influences the narratives about terrorism, radicalism, and combating violent extremism (CVE) in Muslim majority nations such as Malaysia. We contend that some local institutions and researchers in Malaysia may have assumed the Faustian bargain by agreeing with the Western narrative that Islam's teachings promote violence and extremism in order to meet the demands of survival, whether it be funding for everyday operations or meeting the demands of universities or research institutions to sustain themselves and meet their performance indicators. We conducted a systematic literature review (SLR) from 2001 to 2021 and used Foucauldian Critical Discourse Analysis (CDA) to understand the role of the US in purposefully supporting workshops and research activities of particular institutions with the intent to influence national discourse on securitization and prospective policy implications. More importantly, we wish to alert Malaysian policymakers to pay particular attention and scrutinize ongoing programs such as the "Building Community Resilience" as these may inadvertently foster Islamophobia.

Purpose: The purpose of this study was to investigate humanistic knowledge, emotional intelligence, and communication skills among nurses and to identify factors influencing the communication skills of nurses in five hospitals. Methods: Data were collected from 248 nurses in hospitals from August 25 to September 9, 2015. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlations and enter method regression analysis using the SPSS/Win 22.0 program. Results: There were significant differences in humanistic knowledge according to religion, education, work department, number of night duty, pay level satisfaction, job satisfaction, and job performance. There were significant differences in emotional intelligence according to all general characteristics. There were significant differences in communication skills according to education, position, number of night duty, and job performance. Communication skills showed positive correlations with humanistic knowledge and emotional intelligence. Emotional intelligence correlated positively with humanistic knowledge. Emotional intelligence was a significant predictor and accounted for 32% of variance in the communication skills.

While a performance type guarantee is required as a security for non-performance risk by a seller, a payment guarantee is used as a security for non-payment risk by a buyer(or a borrower in a loan agreement). A payment guarantee is a type of independent bank guarantee, bank guarantee, bond, demand guarantee, or standby letter of credit. A guarantor accepts a credit risk of a principal which is normally a buyer in a contract for sale of goods. A payment guarantee is independent of the underlying relationship between the applicant and the beneficiary. The guarantor is only empowered to examine the beneficiary's demand and determine the payment on its face to the terms of the guarantee. A payment guarantee is thus different from a suretyship. The principle of independence carries a significant advantages for a guarantor as well as for a beneficiary. While a documentary credit requires B/L, commercial invoice, packing list, inspection certificate, etc., a typical payment guarantee does not require any evidence for a seller's performance of the underlying contract other than written demand. In this respect payment guarnatee can be a more secured facility than a documentary credit. A payment guarantee normally comes into force from the issuing date and shall remain in effect until all sums guaranteed shall be paid in full by a buyer(or a borrower) or by a guarantor. Although a guarantor shall pay a demand made in accordance with the terms and conditions of the payment guarantee, a payment demand may be denied when it is determined to be abusive or unfair.

낭독공연이란 배우들이 희곡을 암기하지 않고 읽는 것을 통해 관객들에게 희곡의 의미를 전달하는 활동으로 알려져 있다. 이 용어는 오래전부터 사용하였지만, 우리 문화계에서 낭독공연을 주목하기 시작한 것은 2000년대 초라고 할 수 있다. 2015 개정 교육과정에서 연극교육을 강화하면서 '낭독공연'에 관한 관심도 커지고 있다. 이 글에서는 낭독공연을 교육의 장에서 풍부하게 활용할 수 있는 근거를 성인들의 낭독공연에서 찾아보고, 이를 어린이 교육의 장에서 활용하고자 분석하였다. 낭독공연에는 배우들이 무대 위에서 '희곡을 보면서 읽는 유형'과 '희곡을 암기하여 연기하는 유형' 및 '두 유형을 혼합한 유형'이 있다. 결국, 낭독공연의 형식에는 정해진 규칙이 없다는 것이 핵심이다. 희곡을 보거나 보지 않거나 문제 되지 않는다. 낭독공연의 주체가 처한 상황을 고려하여 적합한 형식의 공연을 하되 낭독공연은 꼭 이렇게 해야 한다는 고정관념을 가질 필요는 없다. 어린이와 청소년 또한 낭독희곡의 개념을 유연하게 이해하면 교육적으로 얻을 수 있는 효과가 더 커질 것이다. 이런 분석을 근거로 어린이를 위한 교육의 장에서 활용하기 위한 준거로 '낭독공연의 형식을 한 가지로 고집하지 않기', '여러 유형의 낭독공연 선택하기'를 제시하였다. 그리고 '여러 유형의 낭독공연 선택하기'에 필요한 하위 준거로는 '희곡의 내용 가운데 특정 장면 선택하기', '학생의 수준이나 상황을 고려하기', '새로운 유형의 낭독공연을 만드는 데 주저하지 않기'가 있음을 밝혔다. 이 글이 낭독공연에 관한 논의가 필요한 교육계에 활력을 넣고, 이론의 부재로 인해 교육적 설계가 미흡해지는 점을 해소하는 디딤돌이 되기를 기대한다.

An university dorm has significant implications in terms of providing residential, living, and learning spaces. With its supportive function, a dorm enables each university to provide higher level of education. The operation & maintenance(O&M) condition of the dorm has a decisive effect on the students' satisfaction. Accordingly, high levels of O&M services should be performed for students. However, Korean dorms are being operated and maintained by their own O&M guidelines without the consideration of spatial characteristics of dorm facilities and the comprehensive and systematic understanding on effective O&M processes. Given the fact that dorm facility can be a crucial factor in determining the entire quality of university and its O&M condition is closely related to the satisfaction of students, it is imperative that we need to pay more attention to the O&M condition and services. Therefore, the main objective of this research is to improve dorm students' satisfaction levels by applying different O&M method, preventive maintenance rather than reactive maintenance which has been performed so far. In ordering for doing it, 'Facility Management(FM) Standard' from KS, 'Facility Performance Indicator(FPI)' from APPA: Leadership in educational facilities and 'Building O&M Inspection Manual' from Korean Ministry of Land, Infrastructure and Transport were analyzed to come up with 15 significant O&M factors. After extracting O&M factors, the survey was conducted to determine importance rate and performance rate of each O&M factor. Using the Important-Performance Analysis(IPA), the priority of 15 O&M factors was established. The result of this research will be helpful for the efficient dorm facility O&M services and for facility managers to appropriately allocate the limited resources and human power.

The present paper analyzes performance of a variant of rate-of-return regulation called the ex-post adjustment regulation put in effect in the Korean petroleum refinery sector. Unlike the traditional rate-of-return regulation on a monopoly, the regulation is first for the oligopolistic industry as a whole and second of the ex post nature. Under the regulation, at the end of each year, each firm is responsible to pay a certain portion of the excess of the total realized profits in the industry over the allowed profits. It is shown that if the excess profits are completely collected(including the interests), the social optimum can be realized. When only a portion of the excess profits can be collected, the regulation generally increases consumer surplus by making the firms more competitive. Each individual firm's production under the regulation depends on whether the firm's output is regarded as a strategic substitute or complement of other firms'output.
