Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Hydrochlorofluorocarbon (HCFC) is an ozone-depleting substance that is subject to environmental regulations based on the Montreal Protocol, and in South Korea, which is regarded as a developing country, its use will be restricted in phase starting in 2013 until finally being prohibited in 2030. HCFC is regulated Based on the Tokyo Protocol, HCFC is a regulated construction material for carbon dioxide reduction with GWP of 1,700~2,400 times that of CO₂, with a GWP of 1. At present in South Korea, the foaming agent used for extruded polystyrene insulation consists of solely HCFC, whereas it has been replaced with eco-friendly foaming agents (carbon dioxide, hydrocarbons) by advanced countries such as European countries and Japan as a measure for environmental change. A review of the physical properties of insulation material utilizing CO₂ showed that the compressive strength, flexural failure load, thermal conductivity, combustibility and moisture permeance satisfied the standards of KS M 3808 foaming polystyrene by 4~60%, and it was determined that the foaming agent could be replaced with CO₂ by 30%. Also, it is thought that adding graphite will improve the thermal conductivity of the insulation material.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
