This research is concerned with the current state and uniqueness of Vietnam's Fair Trade through the case study of Fair Trade Organizations (hereafter FTOs) in Vietnam. Vietnam has emerged a successful developing country with rapid economic growth under the socialist regime, while the income gap between the rich and the poor is still growing. Especially the poverty is becoming a serious issue for ethnic minorities and smallholder farmers in the mountainous areas. Fair Trade in the early stage has been initiated, and still is led by the charities and international development agencies of the Global North. But Vietnam's Fair Trade has been introduced by local Vietnamese who have been motivated to solve their own problems voluntarily. This is different from other Fair Trade producing countries in the Global South. It's noticeable that Vietnam's FTOs are playing a significant role of adopting and applying Fair Trade practices. Concerning Fair Trade producing countries the researchers are mostly focusing on Africa and Latin America and the themes are mainly to do with the impact of Fair Trade producers. There are very few research outcomes on the analysis of producing countries' FTOs and their motives and developing processes. The research findings can contribute to understand not only Vietnam's challenges and issues, but also Fair Trade producing countries in general.

After membrane fouling factors in acrylic wastewater were minimized by pretreatment process accompanied with coagulation-filtration-neutralization, it was utilized in UF/RO process. After composing of ultrafiltration and reverse osmosis module set according to types and kinds of membrane, the separation characteristics were examined with the variation temperature and pressure using pretreated acrylic wastewater by membrane module sets. It was found that permeate flux of UF module in module set 4 was about two${\sim}$three times larger than that of UF module in module set 1. Final quantity of permeate from the module set 2 and module set 3 combined with tubular module was shown very good result. It was shown that the removal efficiency of TDS, T-N and COD was very low and was not dependent on the variation of temperature and pressure in all UF modules. The removal efficiency of TDS, T-N and COD was very excellent in RO module. Final water quality of acrylic wastewater was satisfied with effluent allowances limit and membrane module sets were ascertained to reuse wastewater.

건강지향의 식육, 육제품에 대한 사회적 요구에 부응하기 위해 기능성 첨가물 대체 연구로부터 원재료인 신선육과 가공공정 중 식육 단백질의 변성을 제어하고 최적화하기 위한 연구과제로써 온도체 가공/급속동결송풍냉각/저온 세절혼합 조합 기술(처리구)에 대한 유효성이 평가되었다. 그 결과 새로 제안된 조합 공정기술은 기존의 냉도체/수침냉각/세절혼합 조합(대조구)과 비교했을 때 단백질 변성 제어를 통한 기능성 단백질 추출성의 향상으로 인해 신선육의 품질향상뿐만 아니라 가열 처리 후 단백질 겔의 수율과 조직감 모두 증진되었으며, 특히 나트륨을 저감화한 조건($2%{\rightarrow}1%$)에서도 기존의 대조구와 유사한 특성을 보여 나트륨 저감화를 위한 기술로 제안될 수 있었다.

Submerged membrane bioreactor(SMBR) and reverse osmosis(R/O) systems treated dye wastewater for reusing of industrial water. The permeate fluxes of SMBR at 20-25 cmHg of lab. test and field test were 10 LMH($1/m^2$.hr) all test. Removal efficiencies of CODcr, $COD_{Mn}$ and T-N were 93%, 90% and 60% in the SMBR, respectively The advanced treatment of combined process(SMBR+R/0) was accomplished for increasing the removal efficiency of non-biodegradable materials and T-N. Therefore, the removal efficiency of T-N obtained in 80% above, then nitrogen concentration was under 15 mg/L. The combined process(SMBR+R/0) was suitable to reuse of the dye wastewater.

자유 단조는 고온에 가열한 강괴에 높은 압력을 가하여 원하는 형상의 제품을 만드는 공정으로 에너지 소모가 매우 크다. 여러 개의 강괴를 가열로에 장입하여 고온에 가열한 후 소재를 하나씩 꺼내어 프레스 공정을 수행한다. 가열로에 함께 장입되는 소재들의 조합에 따라 가열 시 소요 시간 및 에너지 사용량이 달라진다. 소재 조합에 따른 가열 비용 예측을 통해 최적의 소재 조합을 결정하여 에너지 효율을 높일 수 있다. 비용 예측 모형을 학습하기 위해서는 가열 소요 시간 및 에너지 사용량 데이터가 필요하다. 따라서 본 논문에서는 가열로의 온도 및 가스 사용량 데이터를 이용하여 가열로의 가동 상태 변경 지점을 감지하는 방안을 제안한다. 가열로의 온도 및 가스 사용량은 IoT 인프라를 기반으로 손 쉽게 획득할 수 있다. 가열로의 상태 별로 온도 및 가스 사용량에 나타나는 패턴을 이용하여 상태 변경 지점을 감지한다. 이를 통해 가열 공정 데이터를 획득할 수 있을 뿐만 아니라 가열로의 상태를 실시간에 모니터링이 가능함으로써 불필요하게 가열하는 것을 예방하여 에너지 효율을 높일 수 있다.
