Since the mid-1980s, Taiwan has experienced rapid urban development, marked by the emergence of new apartments in major cities like Taipei. In response to a housing rights movement in the late 1980s, the government announced the construction plan for Danhai New Town. As a result, Danhai New Town became one of Taiwan's most developed areas in the past decade, attracting numerous sandwich-Man due to increased housing advertising demand. The continued presence of sandwich-Man signifies the sustainability of urban development. However, existing research on sandwich-Man does not address their connection to urban development. This report focuses on Danhai New Town's sandwich-Man, aiming to reveal their subjectivity through an consideration of their labor situation and diverse bodily practice.

Atlases for educational purposes are created to suit the developmental stage of children and students, such as elementary education and secondary education, and are called ``School Atlas.'' School atlases from each country are very good at giving an overview of geography education in that country, and because the parts of that country are written in detail, they are very effective for understanding the topography and geography of that country. It is also meaningful as a research subject from these perspectives.

Coldness in summers in the northeastern Japan is a major factor which brought famines in the early modern period. In order to understand spatio-temporal structures of that condition, principal component analysis of sunshine duration at 45 stations in Japan in 1901-2020 is made. In the result of August, the 1st component corresponds to poor sunshine nation-wide with smaller amplitude in the northern Tohoku region, which appeared in 1902, 1905, 1980 and 1993. The 2nd component corresponds to poor sunshine in the northeast and rich sunshine in the southwest, which appeared in 1934.

Located in the Pearl River Delta in southern China, adjacent to Hong Kong, Shenzhen is an economic city whose construction began in 1980. Chinese Communist Party adopted a development policy of "reform and opening-up" and designated four "special economic zones" as experimental zones. As one of these, Shenzhen grew from a remote farming village to an export processing zone and then to a megacity with a population of 17 million. This presentation focuses on China's period of rapid economic growth from the mid-1990s to the mid-2010s, and aims to examine the socioeconomic changes in Shenzhen's urban history.

The Economic Census is pivotal in analyzing regional industries and providing comprehensive universe data. However, concerns arise about underreporting due to evolving internet dynamics and declining survey response rates. This study, focusing on Chiba City, creates a meticulously compiled dataset using legally binding procedure data to scrutinize the extent and biases of underreporting in Economic Census data. Results reveal approximately 40% underreporting compared to the reference dataset. Discrepancies vary across districts, emphasizing the need for detailed analyses. Despite the limitations, the Economic Census remains crucial, urging further cross-sectoral and regional investigations for effective utilization in regional analyses and policy considerations.

On the Musashino Upland in Kodaira City, Tokyo, there are depressions approximately 1 to 3 meters deep. In order to clarify the cause of the depression, microtremor measurements were taken inside and outside the depression to understand the underground S-wave velocity structure. As a result of comparison with the geological cross section, the boundary depth between the Tachikawa loam layer and the Musashino loam layer coincides with the depth at which the S wave velocity changes around 200 m/s. The depth at the top of the Musashino Gravel layer coincided with the depth at which the S-wave velocity changes significantly around 300 m/s. The elevation of the upper end of the Musashino gravel layer was not particularly deep, especially in the depression area. Therefore, the possibility that this depression was formed due to structural factors is considered to be small. On the other hand, the thickness of the Musashino loam layer inside the depression was significantly thinner than outside. Furthermore, there was no significant difference in the thickness of the Tachikawa loam layer between inside and outside the depression. Based on these results, we considered the following landform evolution. When the Musashino loam layer was deposited, there was spring water in the depression, which washed away the deposited loam layer, making the Musashino loam layer in the depression thinner than in the surrounding area. Later, when the Tachikawa loam was deposited, there was no spring water, so there was no major change in the thickness of the loam layer inside and outside the depression.

In Sagarmatha National Park, Nepal, tourism has rapidly developed as a center for mountaineering and trekking, which has influenced the livestock farming that Sherpas have been doing for many years. (Stevens 1993). In this study, we conducted a social survey to clarify current grazing patterns to examine the transformation of livestock farming centered on Sherpas due to external pressure from tourism development.

I Introduction
The Mogami River is a first-class river flowing through Yamagata Prefecture, with about 229 km length (7th in Japan) and about 7,040 km2 drainage basin (9th in Japan). This paper reports the results of a survey to clarify the river water quality in this catchment.
II Methods
Field surveys were conducted approximately once a month from March 2022 to July 2023. Samples taken in September 2022 were analysed for major dissolved constituents by ion chromatography.
III Results and Discussion
The survey results show that nitrate ions increase rapidly in the upper reaches of the Mogami River (Fig. 1). The nitrate concentration was 0.23 mg/L at m01, but increased significantly to 1.52 mg/L at m03. It then decreased to 0.72 mg/L at m06, with no significant change in concentration until m13, and increased again from m14, with a concentration of 1.83 mg/L at m17 at the downstream end. m01-m02 and m02-m03 showed high rates of increase (269.6% and 78.8% in that order), indicating that the nitrate influx in this area, i.e. the Yonezawa Basin The nitrate influx in this area, i.e. in the Yonezawa Basin, was observed. Nitrate ion is assumed to be of human activity origin based on its correlation with the percentage of land use in the basin.
On the other hand, sulphate ion showed a high value of 17.28 mg/L at m01 in the uppermost part of the basin, decreased with the flow down to m09 and increased again to 17.92 mg/L at m10. It then decreases again to 12.52 mg/L at the most downstream m17. Unlike nitrate, sulphate ion has a higher rate of increase between m09-m10, i.e. in the Yamagata Basin (89.6%). Dissolved constituent analysis showed that this sulphate ion is supplied from tributary t19 and that sulphate ions are supplied to t19 by t12 and t13, where sulphate ions predominate (Fig. 2). t12 and t13 sulphate ions are thought to be of sulphur mine or Zao Hot Springs origin and are inferred to be volcanic in origin.
Therefore, it is clear that in the Yonezawa Basin, there is a supply of nitrate ions of human activity origin, while in the Yamagata Basin, there is a supply of sulphate ions of volcanic origin in the mainstream.
IV Conclusion.
This study clarified river water quality in the Mogami River basin with a focus on nitrate and sulphate ions. It is hoped that further clarification of the factors that form the water quality of the river basin will be possible in the future.

Fill material flows created by land development earthworks are anthropogenic agents that generate massive energy use from their heavy loads. However, formal quantification of these flows has been neglected. We use Osaka Prefecture in Japan as a case study to quantify fill flows and associated CO2 emissions. We collected data on fill flows, including fill generation and acceptance. We mapped these publicly uncounted fill flows and calculated the CO2 emissions from the associated energy use. We also simulated a scenario in which optimized shortest-distance matching is achieved between fill generators and acceptors. We estimated the current fill flows based on distance and weight and broke down the total by type of site and activity. We compared our estimates of current fill flows with estimates from our matching simulation and found the simulation could achieve an 8448 km reduction in flow length and a 5724 t-CO2 reduction in emissions associated with transportation. We discussed the implications of flexible matching, especially in different construction sectors, and the importance of continuous, spatially geo-referenced monitoring of these fill flows toward further environmental impact mitigation. The approach presented here could apply to assessing environmental loads arising from landform changes in other cities and lead to development of a new regional- and global-scale fill material science in the Anthropocene.

This study used past and present dead leaves preserved at Dendro Senecio on Mt. Kenya in East Africa to estimate changes in soil moisture and desiccation stress associated with global warming. Radiometric dating of the dead leaves indicated that 160 cm from the top of the tree was dated to 1959, 221 cm to 1960, 280 cm to 1947, 290 cm to 1938, and 400 cm to 1889.
The δ13C of the dead leaf samples ranged between -22‰ and -29‰, with a decreasing trend as the distance from the tree tops became closer (more recent). These results suggest that soil moisture in this study area may have increased with recent global warming.

This study conducted multi-point soil surveys of planting bases in a coastal forest restoration area in Natori City, Miyagi Prefecture, Japan, to understand the spatial distribution of soil properties. The four plots set up all had very different physical and chemical properties in the soil, with the poorest growing areas having a pan layer, high moisture content, low pH, and high EC, an unsuitable environment for tree growth. Furthermore, the values of each soil environmental index varied widely within a few meters, suggesting that the soil environment of the planting base in the study area may be highly heterogeneous.
