Pavement cutting work frequently occurs in new building construction, reconstruction, and complex construction, and this work causes a lot of noise and dust. Eco-friendly pavement cutters are being developed to reduce noise and dust in this work, however the on-site cutting performance of the equipment under development has not been quantified. In this study, the eco-friendly pavement cutter was applied to four residential areas in Seoul and Gyeonggi-do, and its cutting performance was quantified. As a result of the analysis, the eco-friendly pavement cutter showed cutting performance of 20.1~46.9sec/m, and the average was 33.5sec/m. In the future, we plan to conduct additional cutting experiments with various mixing ratios, materials, and depths to confirm the performance of eco-friendly road cutters in more detail.

1. Library practice education in Korea is in the form of field experience, that is, Practicum, which is one type of field experience. 2. The practicum is a short-term work experience guided by the academic institutions. (2 to 6 weeks of full time employment in a library, or one to two semesters of approximately 10 to 12 hours weekly) 3. Field work is largely accepted as a required subject. 4. Field work is usually carried out during the first semester of senior year. (or of sophomore year in junior college) 5. Libraries in other universities (or in other institutions) can beused for a student's field work. But the current tendency is to use his or her own university's library. 6. Most universities give one credit for 2 weeks' field work. 7. The method of evaluation is strict: A or 'excellent' (above 90), B or 'good' (above 80), C or 'fair' (above 70), D or 'bad' (above 60). 8. The expense of field work is usually included in the tuition fees. However, some think that an additional fees should be collected in the case of special practice. 9. Respondents to my survey say that the field experience is necessary so that professional librarians can connect theory and practice. 10. They also indicate that there are some problems in library practice education: administrative difficulties in the department chairman's office, the burden on professors in the library being used, and the limited number of libraries in which the field work is practicable. 11. The Department of Library Science is responsible primarily for providing faculty supervision over the students, and secondarily for the preparation of evaluation cards and field work reports. 12. Most of the faculty respondents use evaluation cards for the field work, some of which serve as grade sheets, some as field work diaries, and some as field work reports.

Purpose: The purpose of this paper is to provide logical basis on enlargement of toilet floor space for the disabled by "ACT ON GUARANTEE OF PROMOTION OF CONVENIENCE OF PERSONS WITH DISABILITIES, THE AGED, PREGNANT WOMEN. ETC" Revised Enforcement regulation [Asterisk 1] (2018.2.10.) and to help with making plans, designs and establishing policies by conducting experimental study with the enhanced floor area regulations. Methods: We conduct Experimental study, field work and interview for this paper. In experimental study, verification of the effective floor area was proceeded by measuring activity space for people in manual wheelchair, electric wheel chair and electric scooter and also reviewed useable area with the space expanded 0.2m both width and depth. In filed work, conducted an observation what other things (ex. sanitary equipment, hand rail and so on) can also affect the active space as well as effective floor space. In the interview, other problems and requirements that were not revealed were experimental study and observation of field work. Results : it's expected to provide better access to toilets for the disabled with the law revision of effective floor area. But, with the usage increasement of enlarged wheel chair and electric wheel chair, expanding side areas of toilet is also highly likely to be required going forward. Implications : Additional research is required on locations of exists and internal arrangement that effect the usage of toilet. It should be led to Universal design by making additional investigation and verification of the users patterns.

Gondola is widely used as a construction facility to perform external finishing work without using scaffolding at a construction site. However, since 2000, there have been 17 deaths from now so these risks associated with work can not be ignored. Therefore, it is expected that it will contribute greatly to prevent related disasters if introducing necessary measures to prevent repeated related disasters and installing additional safety devices. In order to eliminate the risk factor according to the operation of the gondola, it is necessary for the operator to use it to use it while the examination of each product is completed, and to use the over load Dangerous arbitrary measures such as arbitrary operation of the prevention device, removal of the safety fence for convenience of work, installation of the wire rope installed in the air, falling out of the wire rope and falling to the ground Do not perform such sealing measures so that any operation of the overload prevention device can not be done so as not to take such arbitrary measures, or wire the power supply wire to the safety fence so as not to delete the safety fence. Then, when the safety fence is removed, so that it does not become a gondola operation, or when replacing the wire rope in the air, to prevent the wire rope from coming off, Additional measures such as installing falling down prevention device may be necessary.

Background: In contemporary China, most parents are dual-earner couples and there is only one child in the family. We aimed to examine the associations of parents' work stress with suicidal ideation among the corresponding adolescent. We further hypothesized that low parental support experienced by adolescents may mediate the associations. Methods: Cross-sectional data from school students and their working parents were used, with 907 families from Kunming City, China. Stress at work was measured by the effort-reward imbalance questionnaire. Perceived parental support was assessed by an item on parental empathy and their willingness to communicate with the adolescent. Suicidal ideation was considered positive if students reported thoughts about suicide every month or more frequently during the previous 6 months. Logistic regression was used to examine the associations. Results: We observed that parents' work stress was positively associated with low parental support, which was in turn associated with adolescent suicidal ideation. The odds ratio for parents' work stress and adolescent suicidal ideation was 2.91 (95% confidence interval: 1.53-5.53), and this association was markedly attenuated to 2.24 (95% confidence interval: 1.15-4.36) after additional adjustment for parental support. Notably, mothers' work stress levels exerted stronger effects on children's suicidal ideation than those of fathers. Conclusion: Parents' work stress (particularly mother's work stress) was strongly associated with adolescent's suicidal ideation, and the association was partially mediated by low parental support. These results need to be replicated and extended in prospective investigations within and beyond China, in order to explore potential causal pathways as a basis of preventive action.
