Title: Application of Google Earth Engine for Green Space Classification and Green Space Per Capita Ratio Analysis at the Sub-district Level, Mueang Phitsanulok District Authors: Paengwangthong, Napat; Paengwangthong, Wipop Abstract: This research aimed to evaluate the green space per capita status at the sub-district level of Mueang Phitsanulok District for the year 2024, utilizing Sentinel-2 satellite imagery and Google Earth Engine technology for green space classification. The analysis of green space and population data revealed a distinct variation in the green space per capita ratio across sub-districts, ranging from 99.95 sq.m/person in Phitsanulok City Municipality to 7,229.71 sq.m/person in Don Thong Subdistrict. The results, processed through Google Earth Engine, were presented as a thematic map categorizing the green space per capita ratio into three levels: low (<2,495.28 sq.m/person), medium (2,495.28-4,890.24 sq.m/person), and high (>4,890.24 sq.m/person). This highlights a clear disparity in green space accessibility, particularly in urban areas which have low ratios when compared to surrounding rural areas. Therefore, these findings provide essential data to support strategic planning, leading to sustainable development and improved urban livability

Title: A Study of design guideline for lighting temperature office meeting room to increase meeting efficiency at night. Authors: Hundanasevi, Suratchaya; Leeniva, Pasit; Rujibhong, Siriwan Abstract: Individuals of working age increasingly tend to engage in extended working hours, sometimes continuing into the nighttime, especially during prolonged on-site meetings. Under such conditions, artificial lighting becomes the primary source of illumination. Previous research has shown that lighting conditions can significantly affect human health, cognitive function, and emotional well-being. The objectives of this study include: 1) to investigate the effect of lighting color temperature as a contributing factor to meeting performance at night and 2) to recommend suitable lighting color temperature guidelines for office meeting room during nighttime hours. This experimental study involved 20 working-age participants, 10 males and 10 females, aged between 25 and 42 years. Data were collected in a standard office meeting room. Participants initially assessed their fatigue severity levels before starting three types of performance tests: complex thinking, concentration, and creative thinking. These tests were conducted under two lighting Scenarios: 4000K and 6500K, with each condition tested twice and short breaks between sessions. Results found that 4000K lighting enhances concentration and creativity, while 6500K lighting is more effective for complex thinking tasks. Further analysis revealed that 6500K lighting led to greater accuracy in concentration tasks, whereas 4000K lighting resulted in faster performance in those tasks. These findings provide practical implications for improving meeting effectiveness in office environments during nighttime hours.

Title: The satisfaction assessment towards the Legal Aid Center of the Attorney General by adopting a universal design concept Authors: Thongmak, Nitinun; Leeniva, Pasit; Rujibhong, Siriwan Abstract: This research aims to evaluates user satisfaction with the Legal Aid Center for the public of the Office of the Attorney General. The research objectives are divided into four parts as follows: (1) to study the physical characteristics and interior space of the Legal Aid Center, as well as the barriers to access and management issues, (2) to study a universal design concept and the design principles of legal aid centers, (3) to provide recommendations and guidelines for the future development and improvement of the area, and (4) to propose a model of the Legal Aid Center for the public based on a universal design concept. This study employed a qualitative research approach, using purposive sampling to select participants whose characteristics aligned with the research objectives. The study involved 15 participants. Data quality was ensured through triangulation of data sources and methodologies. Data were collected through in-depth interviews, behavioral observations, a Post Occupancy Evaluation (POE) approach and contextual site surveys conducted with measurement tools to record dimensions and equipment, along with a checklist of physical attributes. The data were then compared and validated to ensure accuracy and reliability. The research findings, organized according to the research objectives, revealed that accessibility barriers included details concerning facilities within the space that are part of the physical space. These included problems with usable space dimensions, circulation, signage, doors, furniture, and accessible toilets. These features were not conducive to wheelchair users. The study suggests that incorporating Universal Design principles into the space would allow users to access services independently, without physical constraints or the need for assistance. This approach enhances user confidence and comfort for everyone, reflecting a Legal Aid Center concept that equally responds to users' needs and promotes inclusive usage.

The Lao and Thai Handmade Textile Art

Title: The Lao and Thai Handmade Textile Art Authors: Jaidee, Thanaporn Abstract: This study undertakes a comparative analysis of two distinct and culturally significant textiles: the handwoven fabric of the Lao Khrang people and the Suwannawat cloth of Phetchaburi Province. The primary objective is to explore the textile heritage of Thailand and Laos by examining traditional weaving techniques passed down through generations, tracing their historical development, and uncovering the symbolic meanings embedded in their patterns and colors. This comparison is vital for promoting cultural preservation, understanding the intergenerational transmission of knowledge, and recognizing the role of textiles in fostering social cohesion. These two textiles were selected for their rich yet contrasting narratives and techniques. The Suwannawat cloth, inspired by the ornate pillars of Wat Yai Suwannaram, symbolizes wealth, sophistication, and provincial pride. In contrast, Lao Khrang fabrics incorporate labor-intensive vegetable dyeing processes and nature-inspired motifs that reflect stories of daily life, migration, and ancestral beliefs. Despite differing ering in origin and aesthetic, both traditions embody shared values of spiritual significance, knowledge transmission, and community identity. Through this comparison, the study reveals how weaving functions not only as a craft but as a living medium of cultural expression and social connection. The findings offer academic insights into Southeast Asian textile traditions and serve as practical guidance for efforts in cultural preservation, ensuring these luxurious weaving practices endure as vibrant representations of the diverse cultural landscapes of Thailand and Laos.
