The esterase gene Est8 from the thermophilic bacterium Bacillus sp. K91 was cloned and expressed in Escherichia coli. The monomeric enzyme exhibited a theoretical molecular mass of 24.5 kDa and an optimal activity around $50^{\circ}C$ at pH 9.0. A model of Est8 was constructed using a hypothetical YxiM precursor structure (2O14_A) from Bacillus subtilis as template. The structure showed an ${\alpha}/{\beta}$-hydrolase fold and indicated the presence of a typical catalytic triad consisting of Ser-11, Asp-182, and His-185, which were investigated by site-directed replacements coupled with kinetic characterization. Asp-182 and His-185 residues were more critical than the Ser-11 residue in the catalytic activity of Est8. A comparison of the amino acid sequence showed that Est8 could be grouped into the GDSL family and further classified as an SGNH hydrolase. Est8 is a new member of the SGNH hydrolase subfamily and may employ a different catalytic mechanism.

The purpose of this study is to understand what we have learnt thus far on the sustainable consumption of natural resources by household in Korea. We propose a two-wing model designating households as the main agent of sustainable living where both the production of human resources and the consumption of natural resources take place. In the current study, we focused on the sustainability of natural resource consumption. Undertaking an empirical study, we selected 10 major journals that represent each area of human ecological research and then, identified 120 relevant studies regarding sustainability published since 2000. First, we classified 381 keywords into three categories: production, consumption, and social environment, and the identified studies were then classified in one of the seven categories created by combinations of the abovementioned three categories: production (P), consumption (C), social environment (S), production-consumption (PC), production-social environment (PS), consumption-social environment (CS), and production-consumption-social environment (PCS). The results showed that the sustainability of natural resources has been mainly investigated in the fields of clothing & textiles and food & nutrition. Further, consumer science research has been conducted in the area of consumption-social environment and consumption-production. The current study indicates that the field of human ecology has created and accumulated knowledge to support sustainable living. In the future, we need to conduct more integrated research across disciplines and methods and promote research interest in the underdeveloped area of sustainability research in human ecology.

The harvesting season of lompa fish, Thryssa baelama, through sasi, indigenous knowledge in resources management, in Haruku Village has become a socio-cultural event that attracts many people. The sasi of lompa fish has been conducted for hundreds of years. Information on the bioecology aspect of lompa fish is limited, while this information is crucial for lompa fish sustainability through the sasi approach. This study aimed to investigate some population parameters of lompa fish, its sustainability status, and proposed a sustainable management strategy for the lompa fishery of Haruku Village. Fish population parameter covers length-weight relationship, growth pattern, size distribution, sex ratio, and the body condition index. The sustainability status was assessed following the Rapfish approach. Fisheries management strategy was performed using a conceptual model framework based on Driver Pressure State Impact Response. The research shows that the total length varies between 9.2-14.3 cm. A high relationship was found between total length and weight, and the growth pattern was an allometric negative. There was a difference in sex ratio between males and females, with females dominant. The body condition index varies over time, probably due to reproductive status. The overall sustainability status was at fair condition (61.60%), with the ecological domain having the highest sustainable status (71.07%) and considered sustain. In comparison, the technological domain had the lowest sustainability status (52.58%) and was considered fair sustain. There were seven management strategies proposed for sustainable management for the lompa fishery.

Despite international laws and government efforts, most of the world's fishery resources and ecosystems have continued to decline since the 1970s. In response, international non-governmental organizations have launched sustainable seafood movements and attempted various strategic approaches. These include the "boycott" strategy of the 1980s and 1990s, and the expansion of certified fisheries through Fishery Improvement Projects (FIPs) in the 2000s. According to data from the Marine Stewardship Council (MSC), currently there are 274 MSC-certified fisheries in 63 countries, covering 179 species, and 264 fisheries engaged in FIPs in 67 countries, covering 233 species. In Korea, the adoption of private fishery governance, which complements international and domestic fishery laws and government management, remains relatively low. Therefore, we examined private fishery governance with respect to its governance, interaction with laws, credibility, legitimacy, current status, and key considerations for its implementation. We emphasize the utilizing MSC fishery certification schemes as an audit approach to sustainability, implementating FIPs to address the fisheries sustainability gap, using councils for leadership, and securing government financing for fisheries with no market incentives.
