Two pilot-scale studies were comparatively conducted under tropical conditions during December 1992 to September 1993. One study involved facultative ponds(FP) and the others water spinach ponds(SP). Four rectangular concrete ponds, 0.8 m × 2.4 m × 1.1 m (width × length × depth), were employed to treat the Chiang Mai University campus wastewater. Water spinach (Ipomoea aquatica) was planted in two of the ponds. The influent characteristics noted showed a low organic content, i.e. BOD 25.4-29.9 mg/l, with BOD:N ratio around 1:1. The investigations were conducted using the following hydraulic retention times (HRT): 1.6, 2, 2.7, 4, 8 and 16 d. The results showed that the BOD, COD and SS mass removal rates increased as the mass loading rates increased and the SP was significantly more effective in reducing the organic content than the FP. No relationship was found between TN mass removal and the loading rates. However, the TP mass removal rates in the SP and the FP were rather low and were considered to be insignificant. It was observed that SS accumulated in the water spinach root systems which tended to act as a strainer. This process led to plant growth inhibition and finally die-off. The average water spinach growth rates varied from 37 to 107 g wet wt./(m2.d) and no relationship was established between the growth rates and the HRT.

Major Shift

Social workers were involved in all aspects of the removal, incarceration, and resettlement of the Nikkei, a history that has been forgotten by social work. This study is an effort to address this lacuna. Social work equivocated. While it did not fully endorse mass removal and incarceration, neither did it protest, oppose, or explicitly critique government actions. The past should not be judged by today’s standards; the actions and motivations described here occurred in a period rife with fear and propaganda. Undergoing a major shift from its private charity roots into its public sector future, social work bounded with the rest of society into “a patriotic fervor.” While policies of a government at war, intractable bureaucratic structures, tangled political alliances, and complex professional obligations all may have mandated compliance, it is, nevertheless, difficult to deny that social work and social workers were also willing participants in the events, informed about and aware of the implications of that compliance. In social work’s unwillingness to take a resolute stand against removal and incarceration, the well-intentioned profession, doing its conscious best to do good, enforced the existing social order and did its level best to keep the Nikkei from disrupting it.

Trichobezoars are concretions formed by the accumulation of hair or fibers in the gastrointestinal tract, usually associated with underlying psychiatric disorders in females between 13 and 20 years old. Endoscopy, the gold standard for diagnosis, brings some additional advantages: sample taking, size reducing and, rarely, mass removal. This study shows that endoscopy can cause severe complications resulting in a surgical emergency.

Influence Of Water

Most of the prediction theories regarding dissolution of organic contaminants in the subsurface systems have been proposed based on the static water conditions; and the influence of water fluctuations on mass removal requires further investigations. In this study, it was intended to investigate the effects of water table fluctuations on biogeochemical properties of the contaminated soil at the smear zone between the vadose zone and the groundwater table. An automated 60 cm soil column system was developed and connected to a hydrostatic equilibrium reservoir to impose the water regime by using a multi-channel pump. Four homogenized hydrocarbon contaminated soil columns were constructed and two of them were fully saturated and remained under static water conditions while another two columns were operated under water table fluctuations between the soil surface and 40 cm below it. The experiments were run for 150 days and relevant geochemical indicators as well as dissolved phase concentrations were analyzed at 30 and 50 cm below the soil surface in all columns. The results indicated significant difference in terms of biodegradation effectiveness between the smear zones exposed to static and water table fluctuation conditions. This presentation will provide an overview of the experimental approach, mass removal efficiency, and key findings.

The Government

Social work equivocated. Social work organizations did not support mass removal, landing mostly on the stance that individual adjudication of loyalty rather than wholesale removal was the preferable course. But neither, on the whole, did they oppose wholesale removal, abdicating their right to and responsibility for contesting the wisdom of the government at war. Neither the disciplinary publications nor the archival records of workers in the field provide an unmitigated critique of the events. Even the YWCA, the best of social work in these events, followed the same racist schema that enabled the removal and incarceration. The history presented here is all the more disturbing because it is that of social workers doing what seemed to them to be more or less right and good.
