The public interventions to care work affect women's labor participation as well as quality of care jobs in the market. We identify five different patterns of ways in which care work has been socialized. Some ways of intervention tend to reinforce the commodification of care work through producing it in the market area. Other ways of intervention has a lot of hazard to return care work to women in the families, after all. We can call it re-familization. Whether care work is re-familized or not largely depends on the ways of public supports for care: cash benefit vs. in-kind benefit. Cash benefits for women's care work negatively affect on their labor market participation. The effects vary across family income levels. In other words, you may expect that cash benefits for care work may reduce female labor supply in lower income classes. The marketization of care service provision may worsen the quality of care jobs while the public provision tends to increase the wage level of care jobs.

The main issue of this study is to find ways to lengthen the lifetime of network mainly by reducing energy consumption. This paper proposes how to reduce the amount of data transmitted in each sensor and cluster head in order to lengthen the lifetime of sensor network. The most important factor of reducing the sensor's energy dissipation is to reduce the amount of messages transmitted. This study proposes cluster cohesion for the purposes. The method is to use the cluster cohesion and manage the number of clusters adaptively and reduce the amount of message transmitted in network topology. This method should be much more efficient and effective as it reduces the network traffic significantly and increases the network's lifetime.

This paper proposes a frame-level rate control algorithm for low delay video applications to reduce the fluctuations in the bitrate. The proposed algorithm minimizes the bitrate fluctuations in two ways with minimal coding loss. First, the proposed rate control applies R-Q model to all frames including the first frame of every group of pictures (GOP) except for the first one of a sequence. Conventional rate control algorithms do not use any R-Q models for the first frame of each GOP and do not estimate the generated-bit. An unexpected output rate result from the first frame affects the remainder of the pictures in the rate control. Second, a rate-distortion (R-D) cost is calculated regardless of the hierarchical coding structure for low bitrate fluctuations because the hierarchical coding structure controls the output bitrate in rate distortion optimization (RDO) process. The experimental results show that the average variance of per-frame bits with the proposed algorithm can reduce by approximately 33.8% with a delta peak signal-to-noise ratio (PSNR) degradation of 1.4dB for a "low-delay B" coding structure and by approximately 35.7% with a delta-PSNR degradation of 1.3dB for a "low-delay P" coding structure, compared to HM 8.0 rate control.

This study was developed to provide the basis for efficient bedside training by discovering and analyzing ways to reduce stress when students are in clinical practice. The present study was conducted using a 3-part questionnaire format and was based on 253 participants who were students completing clinical practice. The results showed that environmental factors were the most stressful for students in the department of radiology. According to the questionnaire, the highest factor relating to stress was 'standing for long durations' with a value of $3.27{\pm}1.04$, and values were respectively high in the sections on' disregard when students have a lack of knowledge' and 'repetition in simple tasks'. Students who had a good training atmosphere, good relationships with clinical radiological technologists and other students, and students who had high self-esteem showed low stress levels. The effect on BEPSI scale increased as interpersonal relationships and performance declined. Therefore, training institutions should consider relaxation areas for students, radiological technologists should not ignore the reality that students do not have substantial knowledge in clinical practice and comparisons made between students should not exist. In addition, there is the need to make an effort to reduce stress experienced by students in clinical practice through the use of positive communication and encouragement by assigning various training opportunities, providing areas to sit and initiating relaxation periods for students to reduce fatigue, as well as challenging students rather than restricting them to the simple and repetitive routines they encounter in clinical practice.

The gold standard method for diagnosis of tuberculosis is the isolation of Mycobacterium tuberculosis through culture, but there is a probability of cross-contamination in simultaneous cultures of samples causing false-positives. This can result in delayed treatment of the underlying disease and drug side effects. In this paper, we reviewed studies on false-positive cultures of M. tuberculosis. Rate of occurrence, effective factors, and extent of false-positives were analyzed. Ways to identify and reduce the false-positives and management of them are critical for all laboratories. In most cases, false-positive is occurring in cases with only one positive culture but negative direct smear. The three most crucial factors in this regard are inappropriate technician function, contamination of reagents, and aerosol production. Thus, to reduce false-positives, good laboratory practice, as well as use of whole-genome sequencing or genotyping of all positive culture samples with a robust, extra pure method and rapid response, are essential for minimizing the rate of false-positives. Indeed, molecular approaches and epidemiological surveillance can provide a valuable tool besides culture to identify possible false positives.

Many engineering professors are forced to execute ABEEK activities. Engineering professors are evaluated by their educational, research and service activities, but are mainly by their research papers published in professional journals. The gap between the duties and the evaluation criteria exists among engineering professors. This paper deals with the possible ways of including the ABEEK activities in the engineering professor evaluation system. Among the five ways suggested for a simple survey, tenured professors prefer to reduce the lecture time but junior professors prefer to reduce the research burden for the benefit from executing ABEEK activities. Based on logical reasoning and the preference among the surveyed professors, ABEEK related activities may be included in the educational part for the professor evaluation system before the ABEEK system is matured. However, ABEEK related activities have to be converted to the duties of engineering professors in the long run as in the US universities.

This study provides preliminary data to support the need for appropriate and thorough restoration of quarries through investigating both domestic and overseas cases of sites that were restored in environment-friendly ways to make them re-usable after extraction. In cases of areas where it is difficult to restore the cut slope, putting it to other uses such as engraving buddhist images would be helpful to reduce the restoration cost and enhance the utilization of the slope. Phased land use conversion after exploitation needs to be considered in advance; for example, the location and size of the quarry should be determined according to the pre-planned use or development of the site. Considering the circumstances in the country, serious consideration should be given to methods that allow the restoration or recovery of the damaged sites to be completed in short periods of time. Quarry restoration needs to be approached from the view of ecological restoration and if a site is deemed to be usable for another purpose, land use conversion should be considered to enhance the utilization.

'ISO 37001 - Anti-bribery Management Systems, one of the Business Ethics of Global Standards, is a new standard to help organizations fight bribery and promote an ethical business culture which was developed in 2016. ISO 37001 can provide the tools and systems to greatly reduce the risk and help organizations deal with it effectively if it does arise. After enforcing the Improper Solicitation and Graft Act, Korean government standardized ISO 37001 harmonizing International Standards into Korean Industrial Standards (KS) in 2017. It is meaningful in that Korean companies have localized regulation which applies to global standard anti-bribery management systems. About 100 organizations have adopted ISO 37001 as in the first half of 2019. So far many side effects of other ISO certifications have been recognized. Therefore, it is necessary to investigate the current status of ISO 37001 in Korea for effective operation and management. The primary purpose of this paper is to investigate the current status and problems of ISO 37001 in Korea. It can provide useful guidelines for improving ISO 37001 to manage bribe and corruption effectively.

This paper aims to compare open source software (OSS) with proprietary software (PS), and to propose a new business model for OSS. Generally speaking, PS has made negative impact on software industry in various ways. In contrast, OSS may reduce negative aspects of lock-in effect and transaction cost the ways in which software distribution has been utilized. In this regard, OSS makes it possible to create a new business model, which is software customization. Software customization is not to sell software license directly to end-users, but to create values by means of developing and capitalizing software-related industries where value chain is linked. In other words, the new business model of OSS is focusing on software market where the value created by OSS can be enhanced.
