This study compares domestic and foreign research on renewable energy-based water electrolysis clean hydrogen. Domestic studies from 2010 to 2023 focused on technological efficiency, energy efficiency, and system efficiency, with few analyzing infrastructure and technology trends. Overseas research initially focused on technological efficiency and stability, but has since shifted to economic and environmental impact, policy effectiveness, industry-university-research cooperation, and sustainability. To improve water electrolysis technology production, this study suggests prioritizing technology stability over efficiency, resolving government regulations and resident acceptance issues, promoting industry-university-institute cooperation for rapid commercialization of research results, and developing a strategy for sustainable development of renewable energy-based water electrolysis technology.

The government has switched the purpose of housing policy, from the 'housing supply' to 'housing welfare', with the Housing Laws established in 2015 under evaluation that resident stability and resident standard were improved. But, as 'affordable' housing is gradually decreasing, residential environment has become more poor. Residential environment is a basic element for the child safety, health, and better education. This study explored that the poor resident environment had effect on the child, figured out the situation on housing poverty of domestic child and searched the situation of the residential policy of domestic and foreign child. The main results are as follows. First, the poor resident environment of childhood has a bad effect on the physical health, mental health, academic achievement and cognitive development. Second, 1.29 million children (11.9%) are living in condition of housing poverty below minimum resident standard and are concentrated in certain areas. Third, the policy on housing poverty of domestic child is almost absent and focuses on the elderly, young people. this study discussed political and practical solutions based on these research results. On the basis of these research results, as policy suggestions we proposed housing policy making based on the UN Convention on the Rights of the Child, evidence-based housing policy enforcement and, residential policy suggestions under the responsibility of central government, and as practical suggestions community working as the subject and related agency's solidarity from prevention activity of housing poverty and child advocacy point and we discussed way for issue and analyzed related laws, policies, commitments.

The Korean Housing Lease Act is special law of Civil Code and was enacted from March 5, 1981 as Law No. 3379 to guarantee the stability of residential life. And until January 6, 2015 there were 15 times revisions to protect the right of homeless people. However, it is true that many problems are exposed from enforcement. Because the processing without sufficient review of legislation. and it was enacted very quickly, so, at the part of opposing power that the Article 3 Paragraph 1 "if the housing tenant was delivered rental housing and finish the resident registration, from the day after even if the owner of the house was changed as third party tenant can resist with lease right". In addition, this provision made housing problems of the socially disadvantaged more seriously and the country did not made any way to protect this problems so many issues have been raised and a lot of disputes relating to Housing Lease. Therefore, in this paper derives a problem about opposing power of the Housing Lease Act for tenants of residential stability, and through the foreign legislation case, it propose the improvement to contribute to the residential stability realistically.

This is a basic study designed to discover the most comfortable thermal environment for Korean residences. The purpose of the research is to observe and measure the summer thermal environment in Korean urban detached single family houses and apartments by utilising proposed evaluation standards and methods. The technique used involves the measurement of environmental elements, such as indoor temperature, relative humidity and radiant temperature both in detached single family houses and apartments. Also, in order to understand the resident's thermal comfort response. ASHRAE' thermal sensation 9th level, indoor temperature 5th level, and thermal discomfort 4th level in the psycho-physical voting scale (1972) was used. In conclusion, among Korean urban residences, detached single family houses provided a more stable thermal environment than apartments, as shown by physical psychological evaluations. The possible reason for such stability in detached single family houses may be the usage of reinforced concrete structures which maintain consistent temperatures.

Few attempts have been made to discover the ecological function of coarse woody debris (CWD) despite its importance to small mammal population. Twenty-five pitfall traps and a hundred live traps were placed in three sites with high amounts of CWD and three sites with low amounts of CWD. Eleven species were caught, and Peromyscus maniculatus was the most abundant (45.6%, n=605). Among 11 speices, abundance of Tamias townsendii and Clethronomys gapperi were higher in sites with high amounts of CWD than in sites with low amounts of CWD. Home range size was larger in breeding season than in non-breeding season indicating mating search. Resident time of Peromyscus maniculatus was longer in sites with high amounts of CWD implying better stability in population. The increasing amount of coarse woody debris (CWD) enhanced the habitat use by small mammals, and animals in high amounts of CWD were more abundant and stable in population fluctuation. This study, therefore, concludes that CWD is a critical habitat element for small mammals in forest ecosystem.

The park in city, is more than just ecological function, contributes emotional refinement and psychological stability to citizens, and give satisfaction of social and recreational activities to the citizens. And it is the place of leisure and the place to raise up the quality of urban environment. Especially, the neighborhood park among urban parks occupies the most important position as a leisure space for local resident, but it can not perform its purpose and function as a leisure space, due to its too formal and insufficient facilities. This study, approaching from point of physical method, intends to make types through classifying each parks by built-type and installed facilities which affect human-beings, approaching from point of human-beings, intends to make the using-type analysis of park-users, and the questionnaire.By grasping of their requirements regarding to the characters and facilities what they want, willing to present the fundamental data for effective utility-activating method of small-scaled neighborhood park.

This experiment was performed to evaluate the effect of TSH (thyroid-stimulating) on the ERp29 (endoplasmic reticulum resident 29 kDa protein) gene expression in the rat thyrocytes of FRTL-5 cells. Although ERp29 mRNA was constantly expressed, its expression began to increase remarkably from 10-9 M TSH. and its maximum expression was at 5×10-9 M TSH (about 3.5 fold). On the other hand, the effect of TSH on the abundance of ERp29 mRNA started within 6 h, and peaked at 8 h (about 2.5 fold). Actinomycin D (transcription inhibitor) strongly blocked this effect while cycloheximide (translation inhibitor) did not. The half-life of ERp29 mRNA was about 4.5 h in the presence or absence of TSH that was not affected by the stability of ERp29 mRNA. The effect of TSH on the ERp29 gene expression was specific, while other growth factors (transfferin, insulin, and hydrocortisone) did not alter its expression. Our data indicate for the first time that the expression of ERp29 is regulated transcriptionally by TSH in the thyrocytes.

The Apartment resident's make-up of a family and residing preference are diversified by the change of lifestyle through the elevation of economy level and residing level. Accordingly, the remodeling and the early rebuilding for the satisfaction of a life cycle and a life style are increasing, and "Variability" that is the concept of Open Housing was emphasized as a central of residing plan in the apartment. Although apartments which select the space variability to the residing space are increasing gradually, the optimum composition structural system with space variability that satisfies the structure stability, the economical efficiency and the resident usability is not developed. The method of a study was progressed by a comparison and an analysis on each system with estimation elements through analyzing the development process and the special quality of existing composition structural system with space variability in the apartment. This paper offered the improvement direction on the current composition structural system with space variability for the development of modularizing system that is correct in domestic real condition.

This study aims to establish the measures required for strengthening the internal stability of and executing the systematic plan for Gangwon-do in relation to the "urban regeneration preliminary project" launched by the Ministry of Land, Infrastructure, and Transport. The results of this study are as follows. The unit project carried out via the Gangwon-do urban regeneration preliminary project presented the tendency for the standardization of the H/W and S/W projects such as the establishment of the community anchor space and the resident competency reinforcement project. Further, rather than focusing on the contents that could objectively measure the effects of the project, it concentrated more on the performance indicators that are required for verifying the execution of unit projects like the establishment of buildings and operating programs. It was found to be insufficient with regard to the practicality of the project, the correlation with the New Deal Project, and the validity of the project contents. To improve these aspects, Gangwon-do would be required to highlight its distinguishability from the other regions and increase its practicality by operating the field-centered urban regeneration educational program, inducing the participation of experts in each of the areas in case there is a need to execute a project plan and discover a project with placeness. It also needs to focus on strengthening its connection with the urban regeneration new deal project by discovering the resident leaders and professional manpower, and establishing the performance indicators needed for systematically monitoring the regional changes in accordance to the urban regeneration preliminary project.

During sporulation, Bacillus thuringiensis strains produce crystals consist of toxin proteins highly specific against insect pests. Their host specificities are desirable from a standpoint of environmental safety, but also limit market potential. Thus, development of improved Bacillus thuringiensis strains having broad host spectrum will contribute to increase its use. For the construction of Bacillus thuringiensis strain having broad host spectrum, we cloned cry1C gene encoding a toxin protein highly toxic against Spodoptera exigua from a B. thuringiensis isolate and constructed two recombinant plasmids, pUBClC and plC60. The plasmid PUBC1C has a replication origin of the natural plasmid pBC16 from B. cereus which is closely related species to B. thuringiensis, and the pBC16 was known to be replicated by rolling-circle mechanism. The plasmid pIC60 has a replication origin of a resident 60 MDa plasmid from B. thuringiensis subsp. kurstaki HD263, and it is believed that the pIC60 is replicated in a theta mode. The two plasmids were introduced into B. thuringiensis subsp. kurstaki cryB strain, and the transformed strains produced well-shaped bipyramidal crystals. We confirmed the expression of the cry1C gene by SDS-PAGE, and Western blotting. By investigating the segregational stability, it was found that the plasmid pIC60 is more stable than the pUBC1C.
