It is indispensable for child care centers to investigate and manage indoor air quality (IAQ) because they perform education and day care for children who usually have weak immunity. Nevertheless, there is insufficient research being done, given its importance. This study aims to investigate indoor pollutants' concentration and to seek the causes in order to improve the air quality conditions. Also it aims to secure data which can be used for further researches. Measurements were performed for air temperature, relative humidity, carbon dioxide, carbon monoxide, fine particle mass, formaldehyde and volatile organic compounds. Temperature, humidity, CO and CO2 were measured 30times(1min/time) and PM10 was measured 10times (3min/time). Formaldehyde and volatile organic compounds were measured and analyzed based on The Indoor Air Quality Official Test Method. The results show that the temperatures were within the comfort zone in over half of the centers. CO2 was found to be the main pollutants as its concentration exceeded the IAQ standard. The concentrations of TVOC and PM10 exceeded the standard, by 32% and 24% respectively, whereas those of HCHO and CO were under the standard. HCHO and CO concentrations were under the guideline. 24% of child care centers for education were found to exceed the standard in 2 or more of the pollutants. 82% of were found to exceed the standard by 1 or more. Therefor it is requested for IAQ to manage and improve in child care center for education.

This study aims to examine Japanese elementary school architecture in Meiji Era, in which Japanese modern education system was settled down and the school architecture flourished by mass construction of stereotyped school buildings. It is assumed that stereotyped school architecture is due to the influence of the standard drawings made by Japanese Ministry of Education, therefore standard drawings could be a key to understand the characteristics of the stereotyped school buildings in Meiji Era. In this perspective this study attempts to analyze 4 standard drawings and interpret it in relation to regulations and design guidelines for school architecture in that time. As results of this study the change and characteristics of stereotyped school architecture in Meiji Era are clarified in several categories. They are as follows : the deviation of classroom and corridor, the change of classroom size fixing to 4 kan(間) by 5 kan(間), the absolute use of north-lacing single corridor type block-plan, and the change of other space such as waiting room(控所), special instruction room, auditorium and gymnasium.

In order to prevent the maritime accident, all seafarers who work on fishing vessels over G/T 20 tons are required to undergo the basic safety training by the Seafarer's Act. 45% of domestic crews have boarded on the fishing vessels. However, the fishermen have been trained in accordance with the STCW(International convention on standards of training certification and watch-keeping for seafarers) Convention. But safety training courses for seaman do not reflect on the safety equipment and the limitation of the fishing vessel in the training contents which is organized in accordance with the merchant ship by STCW convention and code. Most of the fishing vessels are small fishing boat of less than G/T 80 tons. Small fishing vessels are operating with only a minimum of safety equipment that has been defined by the fishing vessel safety equipment standard. Due to the safety training that does not fit the situation of the fishing boat, the level of satisfaction by the crews onboard is low for the training. Furthermore, there is a difficulty in achieving the goal of safety education. In order to carry out the safety training that is suitable for fishermen, it is required to provide appropriate standards for the safety education of workers of small fishing boat, by understanding the current state of the domestic fishing vessels. The purpose of this study is to define the aforementioned problems and to provide the standard for the safety education of fishermen. In order to complete the purpose, the research team has conducted a analyzation for registered domestic fishing vessel and safety equipment standard.

Purpose: The purpose of this study was to apply alternative standard setting methods for the Korean Medical Licensing Examination (KMLE), a criterion-referenced written examination, and to compare them to the conventional cut score used on the KMLE. Methods: The process and results of criterion-referenced standard settings (i.e., the modified-Angoff and bookmark methods) were evaluated. The ratio of passing and failing examinees determined using these alternative standard setting methods was compared to the results of the conventional criteria. Additionally, the external, internal and procedural evaluation of these methods were reviewed. Results: The modified-Angoff method yielded the highest cut score, followed sequentially by the conventional method and the bookmark method. The classification agreement between the modified-Angoff and bookmark methods was 0.720 measured by Cohen's ${\kappa}$ coefficient. The intra-panelist classification consistency of modified-Angoff method was higher than bookmark method. However, the inter-panelist classification consistency was vice versa. The standard setting panelists' survey results showed that the procedures of both methods were satisfactory, but panelists had more confidence in the results of the modified-Angoff method. Conclusion: The modified-Angoff method showed results that were more similar to those of the conventional method. Both new methods showed very high concordance with the conventional method, as well as with each other. The modified-Angoff method was considered feasible for adoption on the KMLE. The standard setting panelists responded positively to the modified-Angoff method in terms of its practical applicability, despite certain advantages of the bookmark method.

The objective of this research is to investigate how the board of directors' characteristics influence sustainability disclosures with the mediating effect of corporate governance. The independent variables are the characteristics of the board of directors, which consist of the presence of women on the boards, presence of directors aged over 50 years old, education level, education field, board tenure, and compensation. The dependent variable is sustainability disclosures, which is measured by the GRI standard disclosure, whereas the mediator variable is the CG score. Research samples are 460 companies listed on the Stock Exchange of Thailand (SET). Path Analysis is used to examine the correlation between the board of directors' characteristics, CG score, and GRI standard disclosure. The research findings show that senior boards, the education field, and compensation motivation have an effect on sustainability disclosures, whereas corporate governance is a mediator of the effect of the education field of boards on sustainability disclosures. This finding should help shareholders to choose individuals with suitable characteristics to serve on the board of directors, and, as a result, shareholders should anticipate a profitable result to be generated, while the business of the company is conducted in a sustainable way.
